19
Amaury Forgeot d'Arc14fc6732009-06-23 21:09:09 +000020- Removed the ipaddr module.
21
Raymond Hettinger62641e92009-06-23 20:59:43 +000022- Issue #6329: Fixed iteration for memoryview objects (it was being blocked
23 because it wasn't recognized as a sequence).
24
Benjamin Peterson08a0bbc2009-06-16 00:29:31 +000025- Issue #6289: Encoding errors from compile() were being masked.
26
Benjamin Petersona72be3b2009-06-13 20:23:33 +000027- When no module is given in a relative import, the module field of the
28 ImportFrom AST node is now None instead of an empty string.
29
Benjamin Peterson565e1b62009-06-13 03:46:30 +000030- Assignment to None using import statements now raises a SyntaxError.
31
Benjamin Peterson4afbba32009-06-13 01:40:00 +000032- In the slice AST type, the step field will always be None if a step expression
33 is not specified.
34
Amaury Forgeot d'Arcb02ceda2009-06-01 20:53:18 +000035- Issue #4547: When debugging a very large function, it was not always
36 possible to update the lineno attribute of the current frame.
37
Antoine Pitrou46dbe272009-05-30 21:27:00 +000038- Issue #5330: C functions called with keyword arguments were not reported by
39 the various profiling modules (profile, cProfile). Patch by Hagen Fürstenau.

45 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl944f6842009-05-25 21:02:56 +000046
Benjamin Peterson1880d8b2009-05-25 13:13:44 +000047- Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with

49
Mark Dickinsona4e0efa2009-05-20 18:43:07 +000050- Issue #5829: complex("1e500") no longer raises OverflowError. This
51 makes it consistent with float("1e500") and interpretation of real
52 and imaginary literals.

60
Mark Dickinsonb1d45852009-05-11 15:33:08 +000061- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
62 (1) inf and nan strings with trailing whitespace were incorrectly
63 rejected; (2) parsing of strings representing infinities and nans
64 was locale aware; and (3) the interpretation of fromhex('-nan')
65 didn't match that of float('-nan').
66
Eric Smitha985a3a2009-05-05 18:26:08 +000067- Issue #5920: For float.__format__, change the behavior with the
68 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
69 to be like 'g' but with at least one decimal point and with a
70 default precision of 12. Previously, the behavior the same but with
71 a default precision of 6. This more closely matches str(), and
72 reduces surprises when adding alignment flags to the empty
73 presentation type. This also affects the new complex.__format__ in
74 the same way.
75
R. David Murray7ba8e1c2009-05-04 22:16:24 +000076- Issue #5890: in subclasses of 'property' the __doc__ attribute was
77 shadowed by classtype's, even if it was None. property now
78 inserts the __doc__ into the subclass instance __dict__.
79
Antoine Pitrou653dece2009-05-04 18:32:32 +000080- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
81 sequences. Patch by Nick Barnes and Victor Stinner.
82
Vinay Sajipf9b01fe2009-05-09 12:07:17 +000083- Issue #1588: Add complex.__format__. For example,
Eric Smith9139cc62009-04-30 00:58:58 +000084 format(complex(1, 2./3), '.5') now produces a sensible result.
85
Mark Dickinson92fcc9c2009-04-29 20:41:00 +000086- Issue #5864: Fix empty format code formatting for floats so that it
87 never gives more than the requested number of significant digits.
88
Eric Smithcac7af62009-04-27 19:04:37 +000089- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
90 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
91
Martin v. Löwis99f27792009-04-26 00:53:18 +000092- Issue #4971: Fix titlecase for characters that are their own
93 titlecase, but not their own uppercase.
94
Eric Smith068f0652009-04-25 21:40:15 +000095- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
96 _PyOS_double_to_string or PyOS_double_to_string.
97
Benjamin Peterson5083dc52009-04-25 00:41:22 +000098- Issue #5283: Setting __class__ in __del__ caused a segfault.
99
Mark Dickinson95bc9802009-04-24 12:46:53 +0000100- Issue #5816: complex(repr(z)) now recovers z exactly, even when
101 z involves nans, infs or negative zeros.
102
Eric Smithaca19e62009-04-22 13:29:05 +0000103- Implement PEP 378, Format Specifier for Thousands Separator, for
104 floats, ints, and longs.
105
106- Issue #5515: 'n' formatting for ints, longs, and floats handles
107 leading zero formatting poorly.
108
109- Issue #5772: For float.__format__, don't add a trailing ".0" if
110 we're using no type code and we have an exponent.
111
Mark Dickinson6736cf82009-04-20 21:13:33 +0000112- Issue #3166: Make long -> float (and int -> float) conversions
113 correctly rounded.
114
Benjamin Petersond4d400c2009-04-18 20:12:47 +0000115- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
116 some builtin types.
117
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000118- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000119 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000120
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000121- Issue #5759: float() didn't call __float__ on str subclasses.
122
Georg Brandl3c4a5462009-04-12 12:08:12 +0000123- Issue #5704: the "-3" command-line option now implies "-t".
124
R. David Murray0374a822009-04-09 21:54:50 +0000125- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
126 its clarity and its speed.
127

134
Ronald Oussorene0154ed2009-03-30 23:10:35 +0000135- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
136 the end sys.path, for compatibility with the system install of Python.
137
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000138- Issue #4688: Add a heuristic so that tuples and dicts containing only
139 untrackable objects are not tracked by the garbage collector. This can
140 reduce the size of collections and therefore the garbage collection overhead
141 on long-running programs, depending on their particular use of datatypes.
142
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000143- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
144 improve its performance. Long divisions and remainder operations
145 are now between 50% and 150% faster.
146
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000147- Issue #4258: Make it possible to use base 2**30 instead of base
148 2**15 for the internal representation of integers, for performance
149 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
150 --enable-big-digits option to configure, which overrides the
151 default. Add sys.long_info structseq to provide information about
152 the internal format.
153
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000154- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
155 result traceback.__members__ no longer exists.)
156
Mark Dickinson6b265f12009-03-18 16:07:26 +0000157- Issue #4474: PyUnicode_FromWideChar now converts characters outside
158 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
159 and sizeof(Py_UNICODE) == 2.
160
Eric Smith6f42edb2009-03-14 11:57:26 +0000161- Issue #5237: Allow auto-numbered fields in str.format(). For
162 example: '{} {}'.format(1, 2) == '1 2'.
163
Brett Cannon6c4cff02009-03-11 04:51:06 +0000164- Issue #3652: Make the 'line' argument for warnings.showwarning() a
165 requirement. Means the DeprecationWarning from Python 2.6 can go away.
166
Eric Smithe9fb6862009-02-20 14:02:36 +0000167- Issue #5247: Improve error message when unknown format codes are
168 used when using str.format() with str, unicode, long, int, and
169 float arguments.
170
Raymond Hettinger08259e82009-02-18 23:10:19 +0000171- Running Python with the -3 option now also warns about classic division
172 for ints and longs.
173
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000174- Issue #5260: Long integers now consume less memory: average
175 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
176 on a 64-bit system.
177
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000178- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
179 rotating the object pointer by 4 bits to the right.
180
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000181- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
182 it now forces its argument to double before testing for infinity.
183
Benjamin Petersone18ef192009-01-20 14:21:16 +0000184- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
185
Georg Brandl29c6a282009-04-05 20:23:13 +0000186- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000187 were suppressing all exceptions. These include list(), filter(), map(),
188 zip(), and bytearray().
189
Benjamin Peterson596d3062009-01-19 15:42:23 +0000190- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
191 functions.
192
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000193- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

197
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000198- Issue #4935: The overflow checking code in the expandtabs() method common
199 to str, bytes and bytearray could be optimized away by the compiler, letting
200 the interpreter segfault instead of raising an error.
201
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000202- Issue #3720: Fix a crash when an iterator modifies its class and removes its

208
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000209- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
210 collecting the oldest generation) so that allocating lots of objects without
211 destroying them does not show quadratic performance. Based on a proposal by
212 Martin von Löwis at
213 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
214
Martin v. Löwisb90304a2009-01-07 18:40:40 +0000215- Issue #4850: Change COUNT_ALLOCS variables to Py_ssize_t.
216
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000217- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
218 an existing .py counterpart, override the co_filename attributes of all
219 code objects if the original filename is obsolete (which can happen if the
220 file has been renamed, moved, or if it is accessed through different paths).
221 Patch by Ziga Seilnacht and Jean-Paul Calderone.
222
Martin v. Löwis5344c992009-01-02 20:32:55 +0000223- Issue #4075: Use OutputDebugStringW in Py_FatalError.

232 where the tp_hash and tp_dict slots are both NULL.
233
Benjamin Peterson7af65562008-12-29 17:56:58 +0000234- Issue #4764: With io.open, IOError.filename is set when trying to open a
235 directory on POSIX systems.

244 fail.
245
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000246- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
247 print elapsed times, not only when some objects are uncollectable /
248 unreachable. Original patch by Neil Schemenauer.
249
Mark Dickinson1a707982008-12-17 16:14:37 +0000250- Issue #3439: Add a bit_length method to int and long.

260
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000261- Issue #4445: Replace "sizeof(PyStringObject)" with
262 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
263 str instances. On a typical machine this saves 3 bytes of memory
264 (on average) per string allocation.
265
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000266- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

275
Vinay Sajip213faca2008-12-03 23:22:58 +0000276- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000277 method on file objects with closefd=False. The file descriptor is still
278 kept open but the file object behaves like a closed file. The ``FileIO``
279 object also got a new readonly attribute ``closefd``.
280
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000281- Issue #4348: Some bytearray methods returned that didn't cause any change to

291 exec statement.
292
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000293- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
294 method does not return iterators for the 4th and 5th items.
295
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000296- Issue #4209: Enabling unicode_literals and the print_function in the same
297 __future__ import didn't work.
298

Georg Brandl7fb00ad2008-10-25 07:00:52 +0000300 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000301

307 is temporarily replaced with an equivalent frozenset. But the eventual
308 KeyError would always report the empty frozenset([]) as the missing key. Now
309 it correctly refers to the initial element.

332 of using the replace error handler in PyUnicode_DecodeUTF8().

Michael Foord07ef4872009-05-02 22:43:34 +0000580- Issue #5679: The methods unittest.TestCase.addCleanup and doCleanups were added.
581 addCleanup allows you to add cleanup functions that will be called
582 unconditionally (after setUp if setUp fails, otherwise after tearDown). This
583 allows for much simpler resource allocation and deallocation during tests.
584
585- Issue #3379: unittest.main now takes an optional exit argument. If False main
586 doesn't call sys.exit allowing it to be used from the interactive interpreter.

599 This defaults to False, but if set to True useful error messages are shown in
600 addition to explicit messages passed to assert methods.

649
Gregory P. Smith28399852009-03-31 16:54:10 +0000650- The unittest.TestCase.assertRaises() method now returns a context manager when
651 not given a callable so that code to be tested can be written inline using
652 a with statement.
653
654- The unittest.TestCase.assertEqual() now displays the differences in lists,
655 tuples, dicts and sets on failure. Many new handy type and comparison

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001296- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1297
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001298- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1299 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1300 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1301 ``printf`` function, whereas PyString_FromFormat has an independent
1302 implementation and uses "%zd" on all platforms for size_t values.
1303 This makes a difference on win64, where ``printf`` needs "%Id" to display
1304 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001306- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1310 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001321 was correctly parsed but parsing of subsequent arguments failed.
1322
Vinay Sajip35e3b032008-09-01 14:33:59 +00001323- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001324 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1325 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1326 when given a tuple of classes as second argument, were looking up
1327 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1328 type object.
1329
Neal Norwitz18aa3882008-08-24 05:04:52 +00001330- Fix crashes on memory allocation failure found with failmalloc.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001467What's New in Python 2.6 beta 3?
1468================================
1469
Barry Warsaw07a4a382008-08-21 01:15:08 +00001470*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001471
1472Core and Builtins
1473-----------------
1474
Guido van Rossumf8402962008-08-20 15:01:50 +00001475- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1476 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1477 extensions do not automatically benefit from the class attribute
1478 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1479 to their tp_flags field if they care. This is a backwards
1480 compatibility feature; in 3.0, all types will use the cache by
1481 default.
1482
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001483- Keyword arguments can now follow starred arguments. (``f(a, *args,
1484 keyword=23)`` is now valid syntax.)
1485
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001486- ctypes function pointers that are COM methods have a boolean True
1487 value again.
1488
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001489- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1490 by denying s# to parse objects that have a releasebuffer procedure,
1491 and introducing s*.
1492
Georg Brandl1e13ea92008-08-11 09:07:59 +00001493- Issue #3537: Fix an assertion failure when an empty but presized dict
1494 object was stored in the freelist.
1495
Mark Dickinsonb6467572008-08-04 21:30:09 +00001496- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1497 ValueError consistently across platforms.
1498
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001499- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1500 (64bit Unix, for example), unichr() would truncate its argument and return
1501 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1502
Neal Norwitze7d8be82008-07-31 17:17:14 +00001503- Apply security patches from Apple.
1504
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001505- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1506 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1507
Antoine Pitrou92f82162008-07-25 22:22:08 +00001508- Issue #1819: function calls with several named parameters are now on
1509 average 35% faster (as measured by pybench).
1510
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001511- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1512 the python debugger steps into a class statement: the free variables (local
1513 variables defined in an outer scope) would be deleted from the outer scope.
1514
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001515- Issue #2620: Overflow checking when allocating or reallocating memory
1516 was not always being done properly in some python types and extension
1517 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1518 all been updated to perform better checks and places in the code that
1519 would previously leak memory on the error path when such an allocation
1520 failed have been fixed.
1521
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001522Library
1523-------
1524
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001525- Issue #3612: Added some missing basic types in ctypes.wintypes.
1526
Benjamin Petersone977ad42008-08-20 01:42:01 +00001527- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1528 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1529
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001530- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1531 version reported by these tools does not necessarily follow the python
1532 version numbering scheme, so the module is less strict when parsing it.
1533
Nick Coghlanf70385a2008-08-18 12:42:46 +00001534- Issue #2235: Added Py3k warnings for types which will become unhashable
1535 under the stricter __hash__ inheritance rules in 3.0. Several types
1536 which did not meet the rules for hash invariants and were already
1537 unhashable in 3.0 have now been explicitly flagged as unhashable in
1538 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1539 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1540
Brett Cannon88f801d2008-08-18 00:46:22 +00001541- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1542 imported into the module but exposed as part of the module's API.
1543
Brett Cannon7b96f072008-08-18 00:41:11 +00001544- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1545
Brett Cannon46225e72008-08-18 00:36:52 +00001546- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1547
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001548- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1549
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001550- Issue #3575: Incremental decoder's decode function now takes bytearray
1551 by using 's*' instead of 't#'.
1552
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001553- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001554 fails unicode conversion on 2nd parameter. (windows only)
1555
Facundo Batista94f243a2008-08-17 03:38:39 +00001556- Issue 2464. urllib2 now supports a malformation in the URL received
1557 in a redirect.
1558
Brett Cannonabe423e2008-08-16 21:47:07 +00001559- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001560 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001561
Facundo Batistaeb90b782008-08-16 14:44:07 +00001562- Issue #2776: fixed small issue when handling an URL with double slash
1563 after a 302 response in the case of not going through a proxy.
1564
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001565- Issue #2676: in the email package, content-type parsing was hanging on
1566 pathological input because of quadratic or exponential behaviour of a
1567 regular expression.
1568
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001569- Issue #3476: binary buffered reading through the new "io" library is now
1570 thread-safe.
1571
Brett Cannonbf3157b2008-08-14 05:00:03 +00001572- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1573 since mimetools itself is deprecated. Because modules are cached, all
1574 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1575
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001576- Issue #3134: shutil referenced undefined WindowsError symbol.
1577
Robert Schuppenies14646332008-08-10 11:01:53 +00001578- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1579 menu entries were not deleted.
1580
Brett Cannon83e81842008-08-09 23:30:55 +00001581- Copied the implementation of reduce() to _functools.reduce() to have a
1582 version that did not raise a DeprecationWarning under -3.
1583
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001584- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1585 a MemoryError rather than silently stop the iteration.
1586
Guido van Rossum59ce9012008-08-09 14:55:34 +00001587- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1588 to _sre.compile() will now be rejected. This should not affect anybody
1589 since the re.compile() function never generates invalid re-bytecode.
1590
Skip Montanaroa032bf42008-08-08 22:52:51 +00001591- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1592 upon first access it can be automatically initialized from the csv file if
1593 it wasn't initialized during instantiation.
1594
Brett Cannon3aa2a492008-08-06 22:28:09 +00001595- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1596 the reload() built-in has been removed.
1597
Brett Cannon7e30b672008-08-04 21:52:25 +00001598- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001599 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1603 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1604 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.

1607 raised an AttributeError.
1608
Benjamin Peterson01a24322008-07-28 23:35:27 +00001609- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001610 asking for a specific length. This problem only affected files opened
1611 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001612
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001613- Issue #3449: Update decimal module to use most recent specification
1614 (v. 1.68) and tests (v. 2.58) from IBM.
1615
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001616- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
1617

1624
1625- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1626 invalid arguments.
1627
1628- Issue #3302: Fix several crashes when calling locale's gettext functions
1629 with None arguments.
1630
1631- Issue #3389: Allow resolving dotted names for handlers in logging
1632 configuration files.
1633
1634- Deprecate the sunaudio module for removal in Python 3.0.
1635
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001636- Issue #3394: zipfile.writestr sets external attributes when passed a
1637 file name rather than a ZipInfo instance, so files are extracted with
1638 mode 0600 rather than 000 under Unix.
1639
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001640- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1641 argument in python 2.5, this broke code that subclassed Popen to include its
1642 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001652- Issue #2235: the C API function PyObject_HashNotImplemented and its
1653 interaction with the tp_hash slot (added in 2.6b2) are now documented
1654
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001655- Issue #643841: The language reference now provides more detailed
1656 coverage of the lookup process for special methods. The disclaimers
1657 regarding lack of coverage of new-style classes have also been
1658 removed, since the coverage is now fairly reasonable.

1663
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001664*Release date: 17-Jul-2008*

1667-----------------
1668
Georg Brandl3e483f62008-07-16 22:57:41 +00001669- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1670 its methods now allow for items objects that can be converted to
1671 an integer using operator.index().
1672
Mark Dickinson64b7e502008-07-16 09:40:03 +00001673- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1674 produced a ValueError instead of giving the correct float.
1675
Eric Smitha5fa5a22008-07-16 00:11:49 +00001676- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1677 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1678
Mark Dickinson7103aa42008-07-15 19:08:33 +00001679- Issue #3008: the float type has a new instance method 'float.hex'
1680 and a new class method 'float.fromhex' to convert floating-point
1681 numbers to and from hexadecimal strings, respectively.
1682
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001683- Issue #2235: __hash__ is once again inherited by default. To allow
1684 collections.Hashable to remain meaningful in the presence of the
1685 default hash implementation (object.__hash__), it is now possible
1686 to explicit block inheritance of hash by setting __hash__=None at
1687 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1688 level.
1689
Nick Coghlanb028f502008-07-13 14:52:36 +00001690- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1691 the parent module cannot be found while performing an absolute import.
1692 This means that an incorrectly defined __package__ attribute will
1693 now only prevent relative imports in that module rather than causing
1694 all imports from that module to fail.
1695
Nick Coghlan14ff9942008-07-08 14:21:42 +00001696- Issue #2517: Allow unicode messages in Exceptions again by correctly
1697 bypassing the instance dictionary when looking up __unicode__ on
1698 new-style classes.
1699
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001700- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1701 set to a custom object whose write() method happens to install
1702 another file in sys.stdout.

1706 another thread's dictionary.
1707
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001708- Issue #3004: Minor change to slice.indices(): the start and stop
1709 arguments are now treated identically, making the behaviour easier
1710 to describe and understand. For example, slice(None, -10,
1711 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1712 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1713 10, -1).
1714
Georg Brandl278fc502008-07-19 12:46:12 +00001715- Issue #3219: Calling a function with repeated keyword arguments,

Georg Brandl5cc774e2008-06-11 20:28:06 +00002167 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002168
2169 This is controlled by the configure argument ``--with-universal-archs``:
2170
2171 - ``--with-universal-archs=all``: install 4-way universal
2172
2173 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2174
2175 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2176
2177 This option should be used in combination with ``--enable-universalsdk=``.

2216 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002229- Issue #1631171: Re-implement the 'warnings' module in C (the
2230 original Python code has been kept as backup). This will allow for
2231 using the 'warning's machinery in such places as the parser where
2232 use of pure Python code is not possible. Both the ``showarning()``
2233 and ``formatwarning()`` gain an optional 'line' argument which is
2234 not called by default for backwards-compatibility reasons. Setting
2235 ``warnings.showwarning()`` to an implementation that lacks support
2236 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002261- The getpass module has been improved on Unix. It now uses /dev/tty

Georg Brandl3ee81df2008-05-17 18:14:43 +00002291- Issue #2385: distutils.core.run_script() makes __file__ available,
2292 so the controlled environment will more closely mirror the typical
2293 script environment. This supports setup.py scripts that refer to
2294 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002299- Issue #2550: The approach used by client/server code for obtaining
2300 ports to listen on in network-oriented tests has been refined in an
2301 effort to facilitate running multiple instances of the entire
2302 regression test suite in parallel without issue.
2303 test_support.bind_port() has been fixed such that it will always
2304 return a unique port -- which wasn't always the case with the
2305 previous implementation, especially if socket options had been set
2306 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2307 new implementation of bind_port() will actually raise an exception
2308 if it is passed an AF_INET/SOCK_STREAM socket with either the
2309 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2310 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2311 the socket it's been passed. This currently only applies to
2312 Windows. This option prevents any other sockets from binding to the
2313 host/port we've bound to, thus removing the possibility of the
2314 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2315 when a second SOCK_STREAM socket binds and accepts to a host/port
2316 that's already been bound by another socket. The optional preferred
2317 port parameter to bind_port() has been removed. Under no
2318 circumstances should tests be hard coding ports!
2319
2320 test_support.find_unused_port() has also been introduced, which will
2321 pass a temporary socket object to bind_port() in order to obtain an
2322 unused port. The temporary socket object is then closed and
2323 deleted, and the port is returned. This method should only be used
2324 for obtaining an unused port in order to pass to an external program
2325 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2326 a parameter to a server-oriented class that doesn't give you direct
2327 access to the underlying socket used.
2328
2329 Finally, test_support.HOST has been introduced, which should be used
2330 for the host argument of any relevant socket calls (i.e. bind and
2331 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002332
2333 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002334 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002335 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2336 test_asynchat and test_socket_ssl.
2337
Georg Brandl3ee81df2008-05-17 18:14:43 +00002338 It is now possible for multiple instances of the regression test
2339 suite to run in parallel without issue.

Thomas Heller78b8f442008-03-05 14:53:39 +00002543- The bundled libffi copy is now in sync with the recently released
2544 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002545 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
2546 files are used. On all linux systems the --with-system-ffi
2547 configure option defaults to "yes".

2606-----------------
2607
Fred Drakea8ee94b2008-03-01 02:45:07 +00002608- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002609 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002610
Georg Brandlad61bc82008-02-23 15:11:18 +00002611- Issue #2067: file.__exit__() now calls subclasses' close() method.
2612
2613- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002614
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002615- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002616 issue 215555 for a discussion.
2617
Eric Smitha73fbe72008-02-23 03:09:44 +00002618- Added the future_builtins module, which contains hex() and oct().
2619 These are the PEP 3127 version of these functions, designed to be
2620 compatible with the hex() and oct() builtins from Python 3.0. They
2621 differ slightly in their output formats from the existing, unchanged
2622 Python 2.6 builtins. The expected usage of the future_builtins
2623 module is:
2624 from future_builtins import hex, oct
2625
Eric Smith7ef40bf2008-02-20 23:34:22 +00002626- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2627 exponents for exponents with absolute value < 100. Follows C99
2628 standard. This is a change on Windows, which would use 3 digits.
2629 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2630 so that any alterations it does to the resulting string will be
2631 available in stringlib/formatter.h (for float.__format__).
2632
Eric Smith5a3c1352008-02-19 13:21:56 +00002633- Implemented PEP 3101, Advanced String Formatting. This adds a new
2634 builtin format(); a format() method for str and unicode; a
2635 __format__() method to object, str, unicode, int, long, float, and
2636 datetime; the class string.Formatter; and the C API
2637 PyObject_Format().
2638
Georg Brandl3ee81df2008-05-17 18:14:43 +00002639- Fixed several potential crashes, all caused by specially crafted
2640 __del__ methods exploiting objects in temporarily inconsistent
2641 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002642
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002643- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002644 prevent a possible crash: an Abstract Base Class would try to access
2645 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002646
Georg Brandl3ee81df2008-05-17 18:14:43 +00002647- Fixed repr() and str() of complex numbers with infinity or nan as
2648 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002649
Georg Brandl3ee81df2008-05-17 18:14:43 +00002650- Clear all free lists during a gc.collect() of the highest generation
2651 in order to allow pymalloc to free more arenas. Python may give back
2652 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002653
Georg Brandl3ee81df2008-05-17 18:14:43 +00002654- Issue #2045: Fix an infinite recursion triggered when printing a
2655 subclass of collections.defaultdict, if its default_factory is set
2656 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002657
Christian Heimesf75dbef2008-02-08 00:11:31 +00002658- Fixed a minor memory leak in dictobject.c. The content of the free
2659 list was not freed on interpreter shutdown.
2660
Georg Brandl3ee81df2008-05-17 18:14:43 +00002661- Limit free list of method and builtin function objects to 256
2662 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002663
Georg Brandl3ee81df2008-05-17 18:14:43 +00002664- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2665 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002666 to compact the internal free lists of pre-allocted ints and floats.
2667
Georg Brandl3ee81df2008-05-17 18:14:43 +00002668- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2669 calls. Python expected the return type int but the fork familie
2670 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002671
Georg Brandl3ee81df2008-05-17 18:14:43 +00002672- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2673 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002674
Georg Brandl3ee81df2008-05-17 18:14:43 +00002675- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2676 with the collections.Sequence API.

2682 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002683
Georg Brandl3ee81df2008-05-17 18:14:43 +00002684- Patch #1473257: generator objects gain a gi_code attribute. This is
2685 the same object as the func_code attribute of the function that
2686 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002687
Georg Brandl3ee81df2008-05-17 18:14:43 +00002688- Issue #1920: "while 0" statements were completely removed by the
2689 compiler, even in the presence of an "else" clause, which is
2690 supposed to be run when the condition is false. Now the compiler
2691 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002692
Guido van Rossumeead05f2008-01-24 18:21:02 +00002693- A few crashers fixed: weakref_in_del.py (issue #1377858);
2694 loosing_dict_ref.py (issue #1303614, test67.py);
2695 borrowed_ref_[34].py (not in tracker).
2696
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002697- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002698 suppressed while an extension is loaded by calling SetErrorMode in
2699 dynload_win.c. The error is still reported properly.
2700
Georg Brandl3ee81df2008-05-17 18:14:43 +00002701- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002702 several extension methods and modules do not work without unicode
2703 support.
2704
Georg Brandl26543b12008-01-21 18:36:51 +00002705- Issue #1882: when compiling code from a string, encoding cookies in the
2706 second line of code were not always recognized correctly.
2707
Georg Brandl14404b62008-01-19 19:27:05 +00002708- Issue #1679: "0x" was taken as a valid integer literal.
2709
Georg Brandl6caad7d2008-01-26 14:19:22 +00002710- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002711 added.
2712
Christian Heimesc94e2b52008-01-14 04:13:37 +00002713- sys.float_info / PyFloat_GetInfo: The floating point information
2714 object was converted from a dict to a specialized structseq object.
2715
Georg Brandl3ee81df2008-05-17 18:14:43 +00002716- Patch #1816: Added sys.flags structseq. It exposes the status of
2717 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002718
Georg Brandl3ee81df2008-05-17 18:14:43 +00002719- Objects/structseq.c: Implemented new structseq representation. The
2720 patch makes structseqs (e.g. the return value of os.stat) more
2721 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002722
Georg Brandl3ee81df2008-05-17 18:14:43 +00002723- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00002745 and INF. float("nan"), float("inf") and float("-inf") now work on
2746 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002747
Georg Brandl3ee81df2008-05-17 18:14:43 +00002748- Compiler now generates simpler and faster code for dictionary
2749 literals. The oparg for BUILD_MAP now indicates an estimated
2750 dictionary size. There is a new opcode, STORE_MAP, for adding
2751 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002785- Issue #1265: Fix a problem with sys.settrace, if the tracing
2786 function uses a generator expression when at the same time the
2787 executed code is closing a paused generator.

2792
Neal Norwitz44f326e2007-10-05 05:29:17 +00002793- Fix warnings found by the new version of the Coverity checker.
2794
Georg Brandl3ee81df2008-05-17 18:14:43 +00002795- The enumerate() builtin function is no longer bounded to sequences
2796 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2797 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002798
Georg Brandl3ee81df2008-05-17 18:14:43 +00002799- Issue #1686386: Tuple's tp_repr did not take into account the
2800 possibility of having a self-referential tuple, which is possible
2801 from C code. Nor did object's tp_str consider that a type's tp_str
2802 could do something that could lead to an inifinite recursion.
2803 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2804 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002805
Georg Brandl3ee81df2008-05-17 18:14:43 +00002806- Issue #1164: It was possible to trigger deadlock when using the
2807 'print' statement to write to a file since the GIL was not released
2808 as needed. Now PyObject_Print() does the right thing along with
2809 various tp_print implementations of the built-in types and those in
2810 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002811
Georg Brandl3ee81df2008-05-17 18:14:43 +00002812- Issue #1147: Exceptions were directly allowing string exceptions in
2813 their throw() method even though string exceptions no longer
2814 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002815
Georg Brandl3ee81df2008-05-17 18:14:43 +00002816- Issue #1096: Prevent a segfault from getting the repr of a very
2817 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002818
Brett Cannon1e534b52007-09-07 04:18:30 +00002819- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002820 PyObject_Call() never calling back out to Python code to trigger
2821 recursion depth updates/checks. Required the creation of a static
2822 RuntimeError instance in case normalizing an exception put the
2823 recursion check value past its limit. Fixes crashers
2824 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002825

Neal Norwitz0ac60192007-05-27 04:08:54 +00002839- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002840 __*__ attributes. (Some already existed, e.g., __doc__ and
2841 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002842
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002843- Add -3 option to the interpreter to warn about features that are
2844 deprecated and will be changed/removed in Python 3.0.
2845
Georg Brandl2134e752007-05-21 20:34:16 +00002846- Patch #1686487: you can now pass any mapping after '**' in function
2847 calls.
2848
Collin Winter62903052007-05-18 23:11:24 +00002849- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002850 "except E as target:". This is to provide forwards compatibility
2851 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002852
Brett Cannon229cee22007-05-05 01:34:02 +00002853- Deprecate BaseException.message as per PEP 352.
2854
Georg Brandl3ee81df2008-05-17 18:14:43 +00002855- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002856 inherited from a builtin base.
2857
Vinay Sajip8549ce32007-05-06 17:53:37 +00002858- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002859 setting a plain string, ie don't expand to single letter identifiers.
2860
Raymond Hettinger13936692007-04-11 18:40:58 +00002861- Request #1191699: Slices can now be pickled.
2862
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002863- Request #1193128: str.translate() now allows a None argument for
2864 translations that only remove characters without re-mapping the
2865 remaining characters.
2866
Georg Brandl5cb76c12007-03-21 09:00:39 +00002867- Patch #1682205: a TypeError while unpacking an iterable is no longer
2868 masked by a generic one with the message "unpack non-sequence".
2869
Neal Norwitzaa754b72007-03-21 06:39:48 +00002870- Remove unused file Python/fmod.c.
2871
Guido van Rossum143b5642007-03-23 04:58:42 +00002872- Bug #1683368: The object.__init__() and object.__new__() methods are
2873 now stricter in rejecting excess arguments. The only time when
2874 either allows excess arguments is when it is not overridden and the
2875 other one is. For backwards compatibility, when both are
2876 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002877 warning later). Also, type.__init__() insists on the same signature
2878 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002879
Georg Brandl3ee81df2008-05-17 18:14:43 +00002880- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2881 object to complex using its __complex__() method before falling back
2882 to the __float__() method. Therefore, the functions in the cmath
2883 module now can operate on objects that define a __complex__()
2884 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002885
Georg Brandl3ee81df2008-05-17 18:14:43 +00002886- Patch #1623563: allow __class__ assignment for classes with
2887 __slots__. The old and the new class are still required to have the
2888 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002889

2894 ``object.__reduce_ex__()`` is called with an object that is faking
2895 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002896
Georg Brandl3ee81df2008-05-17 18:14:43 +00002897- Patch #1680015: Don't modify __slots__ tuple if it contains an

2901
Georg Brandl7b9c5552007-03-12 14:30:05 +00002902- Bug #1678647: write a newline after printing an exception in any
2903 case, even when converting the value to a string failed.
2904
Georg Brandl871f1bc2007-03-12 13:17:36 +00002905- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002906 its argument, if it exists. If not, it will work like before. This
2907 allows customizing the output of dir() in the presence of a
2908 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002909
Collin Winter276887b2007-03-12 16:11:39 +00002910- Patch #922167: Python no longer segfaults when faced with infinitely
2911 self-recursive reload() calls (as reported by bug #742342).
2912

Georg Brandl3ee81df2008-05-17 18:14:43 +00002916- Patch #1491866: change the complex() constructor to allow
2917 parthensized forms. This means complex(repr(x)) now works instead of
2918 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002919
Georg Brandlaa2321b2007-03-07 00:40:28 +00002920- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002921 makes the filenames the warning module prints much more sensible
2922 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002923
Georg Brandl49aafc92007-03-07 00:34:46 +00002924- Variant of patch #697613: don't exit the interpreter on a SystemExit
2925 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002926 variable is given, but break into the interactive interpreter just
2927 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00002935- Patch #1674228: when assigning a slice (old-style), check for the
2936 sq_ass_slice instead of the sq_slice slot.
2937
Georg Brandl3ee81df2008-05-17 18:14:43 +00002938- When printing an unraisable error, don't print exceptions. before
2939 the name. This duplicates the behavior whening normally printing
2940 exceptions.

2997
Armin Rigo7ccbca92006-10-04 12:17:45 +00002998- A number of places, including integer negation and absolute value,

3568 -- the failure just occurred later, with a more cumbersome
3569 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003850- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3851 with RFC 3207 and forgets any knowledge obtained from the server not
3852 obtained from the TLS negotiation itself. Patch contributed by Bill
3853 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003854
Georg Brandl3ee81df2008-05-17 18:14:43 +00003855- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003856 that the SMTP.starttls() caller no longer needs to call ehlo()
3857 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003858 does not claim to support starttls. Adds the
3859 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
3860 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003902- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00003903 works as expected. ``mmap.find`` also takes an optional ``end``

Georg Brandl3ee81df2008-05-17 18:14:43 +00003914- itertools.chain() now has an alternate constructor,

3940 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3941 silently miscode subclasses of those types. Now, it raises a
3942 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003943

Georg Brandl3ee81df2008-05-17 18:14:43 +00003958 time so that opening a database previously created with the DB_DUP
3959 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3960 opens. Specifically: dictionary assignment to a DB object will
3961 replace all values for a given key when the database allows
3962 duplicate values. DB users should use DB.put(k, v) when they want
3963 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003964

3970 characters with ASCII value less than 32. Also, it correctly quotes
3971 dots only if they occur on a single line, as opposed to the previous
3972 behavior of quoting dots if they are the second character of any
3973 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003974

4296-----
4297
Georg Brandl3ee81df2008-05-17 18:14:43 +00004298- Unified naming convention for free lists and their limits. All free
4299 lists in Object/ are named ``free_list``, the counter ``numfree``
4300 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4301 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004302
Georg Brandl3ee81df2008-05-17 18:14:43 +00004303- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4304 to ``PyTuple_SetItem``, it can be used to populate a brand new
4305 frozenset; but it does not steal a reference to the added item.

4310 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4311 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004312
4313- Patch #1720595: add T_BOOL to the range of structmember types.
4314
4315- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4316 ``PyFloat_GetInfo()`` to the float API.
4317
Georg Brandl3ee81df2008-05-17 18:14:43 +00004318- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4319 of w# format code incorrectly truncated the length to an int, even
4320 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4321 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004322
Georg Brandl3ee81df2008-05-17 18:14:43 +00004323- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4324 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004326- PEP 3123: Provide forward compatibility with Python 3.0, while
4327 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4328 and PyVarObject_HEAD_INIT.

4340
4341- Fix some leftovers from the conversion from int to Py_ssize_t
4342 (relevant to strings and sequences of more than 2**31 items).
4343
4344- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4345 outside of pystate.c and should not be necessary.
4346
Georg Brandl3ee81df2008-05-17 18:14:43 +00004347- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4348 absolute imports. In earlier versions they might have used relative
4349 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004350
Georg Brandl3ee81df2008-05-17 18:14:43 +00004351- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4352 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004353
Georg Brandl3ee81df2008-05-17 18:14:43 +00004354- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004361- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4362 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4363 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4364 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004365

Georg Brandl3ee81df2008-05-17 18:14:43 +00004379- Removed the macfs module. It had been deprecated since Python 2.5.
4380 This lead to the deprecation of macostools.touched() as it relied
4381 solely on macfs and was a no-op under OS X.
