16 from the .py file to the .pyc file if it is set. Patch by Marco N.
17
Benjamin Peterson753d1622009-07-02 18:16:45 +000018- Issue #4618: When unicode arguments are passed to print(), the default
19 separator and end should be unicode also.
20

Mark Dickinson2f865b92009-06-30 15:32:30 +000024- Issue #6347: Include inttypes.h as well as stdint.h in pyport.h.
25 This fixes a build failure on HP-UX: int32_t and uint32_t are
26 defined in inttypes.h instead of stdint.h on that platform.
27
Hirokazu Yamamotoa3c56092009-06-28 10:23:00 +000028- Issue #4856: Remove checks for win NT.
29
Amaury Forgeot d'Arc595f7a52009-06-25 22:29:29 +000030- Issue #2016: Fixed a crash in a corner case where the dictionary of keyword
31 arguments could be modified during the function call setup.
32
Amaury Forgeot d'Arc14fc6732009-06-23 21:09:09 +000033- Removed the ipaddr module.
34
Raymond Hettinger62641e92009-06-23 20:59:43 +000035- Issue #6329: Fixed iteration for memoryview objects (it was being blocked
36 because it wasn't recognized as a sequence).
37
Benjamin Peterson08a0bbc2009-06-16 00:29:31 +000038- Issue #6289: Encoding errors from compile() were being masked.
39
Benjamin Petersona72be3b2009-06-13 20:23:33 +000040- When no module is given in a relative import, the module field of the
41 ImportFrom AST node is now None instead of an empty string.
42
Benjamin Peterson565e1b62009-06-13 03:46:30 +000043- Assignment to None using import statements now raises a SyntaxError.
44
Benjamin Peterson4afbba32009-06-13 01:40:00 +000045- In the slice AST type, the step field will always be None if a step expression
46 is not specified.
47
Amaury Forgeot d'Arcb02ceda2009-06-01 20:53:18 +000048- Issue #4547: When debugging a very large function, it was not always
49 possible to update the lineno attribute of the current frame.
50
Antoine Pitrou46dbe272009-05-30 21:27:00 +000051- Issue #5330: C functions called with keyword arguments were not reported by

55 function with __func__.
56
Raymond Hettinger822b87f2009-05-29 01:46:48 +000057- Added support for multiple context managers in the same with-statement.
58 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl944f6842009-05-25 21:02:56 +000059
Benjamin Peterson1880d8b2009-05-25 13:13:44 +000060- Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with
61 statement and correctly lookup the __enter__ and __exit__ special methods.
62
Mark Dickinsona4e0efa2009-05-20 18:43:07 +000063- Issue #5829: complex("1e500") no longer raises OverflowError. This
64 makes it consistent with float("1e500") and interpretation of real
65 and imaginary literals.
66
Hirokazu Yamamotoa4f90182009-05-17 02:58:36 +000067- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
68
Benjamin Peterson0c3b4c62009-05-16 23:34:19 +000069- __instancecheck__ and __subclasscheck__ are now completely ignored on classic
70 classes and instances.
Benjamin Petersoneb9fb2c2009-05-16 22:46:11 +000071

73
Mark Dickinsonb1d45852009-05-11 15:33:08 +000074- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
75 (1) inf and nan strings with trailing whitespace were incorrectly
76 rejected; (2) parsing of strings representing infinities and nans
77 was locale aware; and (3) the interpretation of fromhex('-nan')
78 didn't match that of float('-nan').
79
Eric Smitha985a3a2009-05-05 18:26:08 +000080- Issue #5920: For float.__format__, change the behavior with the
81 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
82 to be like 'g' but with at least one decimal point and with a
83 default precision of 12. Previously, the behavior the same but with
84 a default precision of 6. This more closely matches str(), and
85 reduces surprises when adding alignment flags to the empty
86 presentation type. This also affects the new complex.__format__ in
87 the same way.
88
R. David Murray7ba8e1c2009-05-04 22:16:24 +000089- Issue #5890: in subclasses of 'property' the __doc__ attribute was
90 shadowed by classtype's, even if it was None. property now
91 inserts the __doc__ into the subclass instance __dict__.
92
Antoine Pitrou653dece2009-05-04 18:32:32 +000093- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
94 sequences. Patch by Nick Barnes and Victor Stinner.
95
Vinay Sajipf9b01fe2009-05-09 12:07:17 +000096- Issue #1588: Add complex.__format__. For example,
Eric Smith9139cc62009-04-30 00:58:58 +000097 format(complex(1, 2./3), '.5') now produces a sensible result.
98
Mark Dickinson92fcc9c2009-04-29 20:41:00 +000099- Issue #5864: Fix empty format code formatting for floats so that it
100 never gives more than the requested number of significant digits.
101
Eric Smithcac7af62009-04-27 19:04:37 +0000102- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
103 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
104
Martin v. Löwis99f27792009-04-26 00:53:18 +0000105- Issue #4971: Fix titlecase for characters that are their own
106 titlecase, but not their own uppercase.
107
Eric Smith068f0652009-04-25 21:40:15 +0000108- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
109 _PyOS_double_to_string or PyOS_double_to_string.
110
Benjamin Peterson5083dc52009-04-25 00:41:22 +0000111- Issue #5283: Setting __class__ in __del__ caused a segfault.
112
Mark Dickinson95bc9802009-04-24 12:46:53 +0000113- Issue #5816: complex(repr(z)) now recovers z exactly, even when
114 z involves nans, infs or negative zeros.
115
Eric Smithaca19e62009-04-22 13:29:05 +0000116- Implement PEP 378, Format Specifier for Thousands Separator, for
117 floats, ints, and longs.
118
119- Issue #5515: 'n' formatting for ints, longs, and floats handles
120 leading zero formatting poorly.
121
122- Issue #5772: For float.__format__, don't add a trailing ".0" if
123 we're using no type code and we have an exponent.
124
Mark Dickinson6736cf82009-04-20 21:13:33 +0000125- Issue #3166: Make long -> float (and int -> float) conversions
126 correctly rounded.
127
Benjamin Petersond4d400c2009-04-18 20:12:47 +0000128- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
129 some builtin types.
130
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000131- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000132 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000133
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000134- Issue #5759: float() didn't call __float__ on str subclasses.
135
Georg Brandl3c4a5462009-04-12 12:08:12 +0000136- Issue #5704: the "-3" command-line option now implies "-t".
137
R. David Murray0374a822009-04-09 21:54:50 +0000138- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
139 its clarity and its speed.

147
Ronald Oussorene0154ed2009-03-30 23:10:35 +0000148- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
149 the end sys.path, for compatibility with the system install of Python.
150
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000151- Issue #4688: Add a heuristic so that tuples and dicts containing only
152 untrackable objects are not tracked by the garbage collector. This can
153 reduce the size of collections and therefore the garbage collection overhead
154 on long-running programs, depending on their particular use of datatypes.
155
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000156- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
157 improve its performance. Long divisions and remainder operations
158 are now between 50% and 150% faster.
159
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000160- Issue #4258: Make it possible to use base 2**30 instead of base
161 2**15 for the internal representation of integers, for performance
162 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
163 --enable-big-digits option to configure, which overrides the
164 default. Add sys.long_info structseq to provide information about
165 the internal format.
166
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000167- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
168 result traceback.__members__ no longer exists.)
169
Mark Dickinson6b265f12009-03-18 16:07:26 +0000170- Issue #4474: PyUnicode_FromWideChar now converts characters outside
171 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
172 and sizeof(Py_UNICODE) == 2.
173
Eric Smith6f42edb2009-03-14 11:57:26 +0000174- Issue #5237: Allow auto-numbered fields in str.format(). For
175 example: '{} {}'.format(1, 2) == '1 2'.
176
Brett Cannon6c4cff02009-03-11 04:51:06 +0000177- Issue #3652: Make the 'line' argument for warnings.showwarning() a
178 requirement. Means the DeprecationWarning from Python 2.6 can go away.
179
Eric Smithe9fb6862009-02-20 14:02:36 +0000180- Issue #5247: Improve error message when unknown format codes are
181 used when using str.format() with str, unicode, long, int, and
182 float arguments.
183
Raymond Hettinger08259e82009-02-18 23:10:19 +0000184- Running Python with the -3 option now also warns about classic division
185 for ints and longs.
186
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000187- Issue #5260: Long integers now consume less memory: average
188 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
189 on a 64-bit system.
190
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000191- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
192 rotating the object pointer by 4 bits to the right.
193
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000194- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
195 it now forces its argument to double before testing for infinity.
196
Benjamin Petersone18ef192009-01-20 14:21:16 +0000197- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
198
Georg Brandl29c6a282009-04-05 20:23:13 +0000199- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000200 were suppressing all exceptions. These include list(), filter(), map(),
201 zip(), and bytearray().
202
Benjamin Peterson596d3062009-01-19 15:42:23 +0000203- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
204 functions.
205
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000206- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

210
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000211- Issue #4935: The overflow checking code in the expandtabs() method common
212 to str, bytes and bytearray could be optimized away by the compiler, letting
213 the interpreter segfault instead of raising an error.
214
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000215- Issue #3720: Fix a crash when an iterator modifies its class and removes its
216 __next__ method.

221
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000222- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
223 collecting the oldest generation) so that allocating lots of objects without
224 destroying them does not show quadratic performance. Based on a proposal by
225 Martin von Löwis at
226 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
227
Martin v. Löwisb90304a2009-01-07 18:40:40 +0000228- Issue #4850: Change COUNT_ALLOCS variables to Py_ssize_t.
229
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000230- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
231 an existing .py counterpart, override the co_filename attributes of all
232 code objects if the original filename is obsolete (which can happen if the
233 file has been renamed, moved, or if it is accessed through different paths).
234 Patch by Ziga Seilnacht and Jean-Paul Calderone.
235
Martin v. Löwis5344c992009-01-02 20:32:55 +0000236- Issue #4075: Use OutputDebugStringW in Py_FatalError.
237
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000238- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open

245 where the tp_hash and tp_dict slots are both NULL.
246
Benjamin Peterson7af65562008-12-29 17:56:58 +0000247- Issue #4764: With io.open, IOError.filename is set when trying to open a
248 directory on POSIX systems.
249
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000250- Issue #4764: IOError.filename is set when trying to open a directory on POSIX

257 fail.
258
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000259- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
260 print elapsed times, not only when some objects are uncollectable /
261 unreachable. Original patch by Neil Schemenauer.
262
Mark Dickinson1a707982008-12-17 16:14:37 +0000263- Issue #3439: Add a bit_length method to int and long.

272 exceptions.
273
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000274- Issue #4445: Replace "sizeof(PyStringObject)" with
275 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
276 str instances. On a typical machine this saves 3 bytes of memory
277 (on average) per string allocation.
278
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000279- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
280 interpreter to abort ("Fatal Python error: Could not reset the stack!")
281 instead of throwing a MemoryError.
282
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000283- Issue #3689: The list reversed iterator now supports __length_hint__
284 instead of __len__. Behavior now matches other reversed iterators.
285
Benjamin Petersonc078f922008-11-21 22:27:24 +0000286- Issue #4367: Python would segfault during compiling when the unicodedata
287 module couldn't be imported and \N escapes were present.
288
Vinay Sajip213faca2008-12-03 23:22:58 +0000289- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000290 method on file objects with closefd=False. The file descriptor is still
291 kept open but the file object behaves like a closed file. The ``FileIO``
292 object also got a new readonly attribute ``closefd``.
293
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000294- Issue #4348: Some bytearray methods returned that didn't cause any change to
295 the bytearray, returned the same bytearray instead of a copy.
296

1177 for the integer formats ('bBhHiIlLqQ'). In the following, '*'
1178 represents any of '=', '<', '>'.
1179
1180 - Packing a float now always gives a Deprecation Warning.
1181 Previously it only warned for 'I', 'L', '*B', '*H', '*I', '*L'.
1182
1183 - If x is not an int, long or float, then packing x will always
1184 result in struct.error. Previously an x with an __int__ method
1185 could be packed by 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h'
1186 ,'*i', '*l', and an x with a __long__ method could be packed by
1187 'q', 'Q', '*q', '*Q'; for x with neither __int__ nor __long__,

1339
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001340- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1341 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1342 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1343 ``printf`` function, whereas PyString_FromFormat has an independent
1344 implementation and uses "%zd" on all platforms for size_t values.
1345 This makes a difference on win64, where ``printf`` needs "%Id" to display
1346 64bit values.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001363 was correctly parsed but parsing of subsequent arguments failed.
1364
Vinay Sajip35e3b032008-09-01 14:33:59 +00001365- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001366 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1367 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1368 when given a tuple of classes as second argument, were looking up
1369 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1370 type object.

1441 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1442 for catch_warnings() also led to an improvement in the raising of a
1443 DeprecationWarning related to warnings.warn_explicit().
1444
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001445- The deprecation warnings for the old camelCase threading API were removed.

1467
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001468- Issue #2975: When compiling several extension modules with Visual Studio 2008
1469 from the same python interpreter, some environment variables would grow
1470 without limit.
1471
Benjamin Peterson37346b22008-08-23 20:27:43 +00001472- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

1479
Gerhard Häringe6872eb2008-09-12 22:33:22 +00001480- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001509What's New in Python 2.6 beta 3?
1510================================
1511
Barry Warsaw07a4a382008-08-21 01:15:08 +00001512*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001513
1514Core and Builtins
1515-----------------
1516
Guido van Rossumf8402962008-08-20 15:01:50 +00001517- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1518 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1519 extensions do not automatically benefit from the class attribute
1520 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1521 to their tp_flags field if they care. This is a backwards
1522 compatibility feature; in 3.0, all types will use the cache by
1523 default.
1524
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001525- Keyword arguments can now follow starred arguments. (``f(a, *args,
1526 keyword=23)`` is now valid syntax.)
1527
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001528- ctypes function pointers that are COM methods have a boolean True
1529 value again.
1530
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001531- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1532 by denying s# to parse objects that have a releasebuffer procedure,
1533 and introducing s*.
1534
Georg Brandl1e13ea92008-08-11 09:07:59 +00001535- Issue #3537: Fix an assertion failure when an empty but presized dict
1536 object was stored in the freelist.
1537
Mark Dickinsonb6467572008-08-04 21:30:09 +00001538- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1539 ValueError consistently across platforms.
1540
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001541- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1542 (64bit Unix, for example), unichr() would truncate its argument and return
1543 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1544
Neal Norwitze7d8be82008-07-31 17:17:14 +00001545- Apply security patches from Apple.
1546
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001547- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1548 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1549
Antoine Pitrou92f82162008-07-25 22:22:08 +00001550- Issue #1819: function calls with several named parameters are now on
1551 average 35% faster (as measured by pybench).
1552
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001553- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1554 the python debugger steps into a class statement: the free variables (local
1555 variables defined in an outer scope) would be deleted from the outer scope.
1556
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001557- Issue #2620: Overflow checking when allocating or reallocating memory
1558 was not always being done properly in some python types and extension
1559 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1560 all been updated to perform better checks and places in the code that
1561 would previously leak memory on the error path when such an allocation
1562 failed have been fixed.
1563
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001564Library
1565-------
1566
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001567- Issue #3612: Added some missing basic types in ctypes.wintypes.
1568
Benjamin Petersone977ad42008-08-20 01:42:01 +00001569- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1570 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1571
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001572- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1573 version reported by these tools does not necessarily follow the python
1574 version numbering scheme, so the module is less strict when parsing it.
1575
Nick Coghlanf70385a2008-08-18 12:42:46 +00001576- Issue #2235: Added Py3k warnings for types which will become unhashable
1577 under the stricter __hash__ inheritance rules in 3.0. Several types
1578 which did not meet the rules for hash invariants and were already
1579 unhashable in 3.0 have now been explicitly flagged as unhashable in
1580 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1581 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1582
Brett Cannon88f801d2008-08-18 00:46:22 +00001583- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1584 imported into the module but exposed as part of the module's API.

1587
Brett Cannon46225e72008-08-18 00:36:52 +00001588- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001590- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1591
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001592- Issue #3575: Incremental decoder's decode function now takes bytearray
1593 by using 's*' instead of 't#'.
1594
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001595- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001596 fails unicode conversion on 2nd parameter. (windows only)
1597
Facundo Batista94f243a2008-08-17 03:38:39 +00001598- Issue 2464. urllib2 now supports a malformation in the URL received
1599 in a redirect.
1600
Brett Cannonabe423e2008-08-16 21:47:07 +00001601- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001602 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001603
Facundo Batistaeb90b782008-08-16 14:44:07 +00001604- Issue #2776: fixed small issue when handling an URL with double slash
1605 after a 302 response in the case of not going through a proxy.
1606
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001607- Issue #2676: in the email package, content-type parsing was hanging on
1608 pathological input because of quadratic or exponential behaviour of a
1609 regular expression.
1610
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001611- Issue #3476: binary buffered reading through the new "io" library is now
1612 thread-safe.
1613
Brett Cannonbf3157b2008-08-14 05:00:03 +00001614- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1615 since mimetools itself is deprecated. Because modules are cached, all
1616 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1617
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001618- Issue #3134: shutil referenced undefined WindowsError symbol.
1619
Robert Schuppenies14646332008-08-10 11:01:53 +00001620- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1621 menu entries were not deleted.
1622
Brett Cannon83e81842008-08-09 23:30:55 +00001623- Copied the implementation of reduce() to _functools.reduce() to have a
1624 version that did not raise a DeprecationWarning under -3.
1625
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001626- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1627 a MemoryError rather than silently stop the iteration.
1628
Guido van Rossum59ce9012008-08-09 14:55:34 +00001629- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1630 to _sre.compile() will now be rejected. This should not affect anybody
1631 since the re.compile() function never generates invalid re-bytecode.
1632
Skip Montanaroa032bf42008-08-08 22:52:51 +00001633- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1634 upon first access it can be automatically initialized from the csv file if
1635 it wasn't initialized during instantiation.
1636
Brett Cannon3aa2a492008-08-06 22:28:09 +00001637- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1638 the reload() built-in has been removed.
1639
Brett Cannon7e30b672008-08-04 21:52:25 +00001640- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001641 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001652 asking for a specific length. This problem only affected files opened
1653 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001654

1679 file name rather than a ZipInfo instance, so files are extracted with
1680 mode 0600 rather than 000 under Unix.
1681
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001682- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

1698 coverage of the lookup process for special methods. The disclaimers
1699 regarding lack of coverage of new-style classes have also been
1700 removed, since the coverage is now fairly reasonable.

1710
Georg Brandl3e483f62008-07-16 22:57:41 +00001711- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1712 its methods now allow for items objects that can be converted to
1713 an integer using operator.index().
1714
Mark Dickinson64b7e502008-07-16 09:40:03 +00001715- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1716 produced a ValueError instead of giving the correct float.
1717
Eric Smitha5fa5a22008-07-16 00:11:49 +00001718- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1719 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1720
Mark Dickinson7103aa42008-07-15 19:08:33 +00001721- Issue #3008: the float type has a new instance method 'float.hex'

1723 numbers to and from hexadecimal strings, respectively.
1724
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001725- Issue #2235: __hash__ is once again inherited by default. To allow
1726 collections.Hashable to remain meaningful in the presence of the

Nick Coghlanb028f502008-07-13 14:52:36 +00001732- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1733 the parent module cannot be found while performing an absolute import.
1734 This means that an incorrectly defined __package__ attribute will
1735 now only prevent relative imports in that module rather than causing
1736 all imports from that module to fail.

Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001750- Issue #3004: Minor change to slice.indices(): the start and stop
1751 arguments are now treated identically, making the behaviour easier
1752 to describe and understand. For example, slice(None, -10,
1753 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1754 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1755 10, -1).

2258 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002271- Issue #1631171: Re-implement the 'warnings' module in C (the
2272 original Python code has been kept as backup). This will allow for
2273 using the 'warning's machinery in such places as the parser where
2274 use of pure Python code is not possible. Both the ``showarning()``
2275 and ``formatwarning()`` gain an optional 'line' argument which is
2276 not called by default for backwards-compatibility reasons. Setting
2277 ``warnings.showwarning()`` to an implementation that lacks support
2278 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002341- Issue #2550: The approach used by client/server code for obtaining
2342 ports to listen on in network-oriented tests has been refined in an
2343 effort to facilitate running multiple instances of the entire
2344 regression test suite in parallel without issue.
2345 test_support.bind_port() has been fixed such that it will always
2346 return a unique port -- which wasn't always the case with the
2347 previous implementation, especially if socket options had been set
2348 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2349 new implementation of bind_port() will actually raise an exception
2350 if it is passed an AF_INET/SOCK_STREAM socket with either the
2351 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2352 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2353 the socket it's been passed. This currently only applies to
2354 Windows. This option prevents any other sockets from binding to the
2355 host/port we've bound to, thus removing the possibility of the
2356 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2357 when a second SOCK_STREAM socket binds and accepts to a host/port
2358 that's already been bound by another socket. The optional preferred
2359 port parameter to bind_port() has been removed. Under no
2360 circumstances should tests be hard coding ports!
2361
2362 test_support.find_unused_port() has also been introduced, which will
2363 pass a temporary socket object to bind_port() in order to obtain an
2364 unused port. The temporary socket object is then closed and
2365 deleted, and the port is returned. This method should only be used
2366 for obtaining an unused port in order to pass to an external program
2367 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2368 a parameter to a server-oriented class that doesn't give you direct
2369 access to the underlying socket used.
2370
2371 Finally, test_support.HOST has been introduced, which should be used
2372 for the host argument of any relevant socket calls (i.e. bind and
2373 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002374
2375 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002376 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002377 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2378 test_asynchat and test_socket_ssl.
2379
Georg Brandl3ee81df2008-05-17 18:14:43 +00002380 It is now possible for multiple instances of the regression test
2381 suite to run in parallel without issue.

2648-----------------
2649
Fred Drakea8ee94b2008-03-01 02:45:07 +00002650- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002651 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002652
Georg Brandlad61bc82008-02-23 15:11:18 +00002653- Issue #2067: file.__exit__() now calls subclasses' close() method.
2654
2655- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002656
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002657- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002658 issue 215555 for a discussion.
2659
Eric Smitha73fbe72008-02-23 03:09:44 +00002660- Added the future_builtins module, which contains hex() and oct().
2661 These are the PEP 3127 version of these functions, designed to be
2662 compatible with the hex() and oct() builtins from Python 3.0. They
2663 differ slightly in their output formats from the existing, unchanged
2664 Python 2.6 builtins. The expected usage of the future_builtins
2665 module is:
2666 from future_builtins import hex, oct
2667
Eric Smith7ef40bf2008-02-20 23:34:22 +00002668- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2669 exponents for exponents with absolute value < 100. Follows C99
2670 standard. This is a change on Windows, which would use 3 digits.
2671 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2672 so that any alterations it does to the resulting string will be
2673 available in stringlib/formatter.h (for float.__format__).
2674
Eric Smith5a3c1352008-02-19 13:21:56 +00002675- Implemented PEP 3101, Advanced String Formatting. This adds a new
2676 builtin format(); a format() method for str and unicode; a
2677 __format__() method to object, str, unicode, int, long, float, and
2678 datetime; the class string.Formatter; and the C API
2679 PyObject_Format().
2680
Georg Brandl3ee81df2008-05-17 18:14:43 +00002681- Fixed several potential crashes, all caused by specially crafted
2682 __del__ methods exploiting objects in temporarily inconsistent
2683 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002684
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002685- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002686 prevent a possible crash: an Abstract Base Class would try to access
2687 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002688
Georg Brandl3ee81df2008-05-17 18:14:43 +00002689- Fixed repr() and str() of complex numbers with infinity or nan as
2690 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002691
Georg Brandl3ee81df2008-05-17 18:14:43 +00002692- Clear all free lists during a gc.collect() of the highest generation
2693 in order to allow pymalloc to free more arenas. Python may give back
2694 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002695
Georg Brandl3ee81df2008-05-17 18:14:43 +00002696- Issue #2045: Fix an infinite recursion triggered when printing a
2697 subclass of collections.defaultdict, if its default_factory is set
2698 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002699
Christian Heimesf75dbef2008-02-08 00:11:31 +00002700- Fixed a minor memory leak in dictobject.c. The content of the free
2701 list was not freed on interpreter shutdown.
2702
Georg Brandl3ee81df2008-05-17 18:14:43 +00002703- Limit free list of method and builtin function objects to 256
2704 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002705
Georg Brandl3ee81df2008-05-17 18:14:43 +00002706- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2707 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002708 to compact the internal free lists of pre-allocted ints and floats.
2709
Georg Brandl3ee81df2008-05-17 18:14:43 +00002710- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2711 calls. Python expected the return type int but the fork familie
2712 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002713
Georg Brandl3ee81df2008-05-17 18:14:43 +00002714- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2715 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002716
Georg Brandl3ee81df2008-05-17 18:14:43 +00002717- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2718 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002719

Georg Brandl3ee81df2008-05-17 18:14:43 +00002723- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2724 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002725
Georg Brandl3ee81df2008-05-17 18:14:43 +00002726- Patch #1473257: generator objects gain a gi_code attribute. This is
2727 the same object as the func_code attribute of the function that
2728 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002729
Georg Brandl3ee81df2008-05-17 18:14:43 +00002730- Issue #1920: "while 0" statements were completely removed by the
2731 compiler, even in the presence of an "else" clause, which is
2732 supposed to be run when the condition is false. Now the compiler
2733 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002734
Guido van Rossumeead05f2008-01-24 18:21:02 +00002735- A few crashers fixed: weakref_in_del.py (issue #1377858);
2736 loosing_dict_ref.py (issue #1303614, test67.py);
2737 borrowed_ref_[34].py (not in tracker).
2738
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002739- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002740 suppressed while an extension is loaded by calling SetErrorMode in
2741 dynload_win.c. The error is still reported properly.
2742
Georg Brandl3ee81df2008-05-17 18:14:43 +00002743- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002744 several extension methods and modules do not work without unicode
2745 support.
2746
Georg Brandl26543b12008-01-21 18:36:51 +00002747- Issue #1882: when compiling code from a string, encoding cookies in the
2748 second line of code were not always recognized correctly.
2749
Georg Brandl14404b62008-01-19 19:27:05 +00002750- Issue #1679: "0x" was taken as a valid integer literal.
2751
Georg Brandl6caad7d2008-01-26 14:19:22 +00002752- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002753 added.
2754
Christian Heimesc94e2b52008-01-14 04:13:37 +00002755- sys.float_info / PyFloat_GetInfo: The floating point information
2756 object was converted from a dict to a specialized structseq object.
2757
Georg Brandl3ee81df2008-05-17 18:14:43 +00002758- Patch #1816: Added sys.flags structseq. It exposes the status of
2759 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002760
Georg Brandl3ee81df2008-05-17 18:14:43 +00002761- Objects/structseq.c: Implemented new structseq representation. The
2762 patch makes structseqs (e.g. the return value of os.stat) more
2763 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002764
Georg Brandl3ee81df2008-05-17 18:14:43 +00002765- Patch #1700288: added a type attribute cache that caches method

2774 envvar and sys.dont_write_bytecode attribute. All these can be set
2775 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002776
Georg Brandl3ee81df2008-05-17 18:14:43 +00002777- Improve some exception messages when Windows fails to load an
2778 extension module. Now we get for example '%1 is not a valid Win32
2779 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002780

Christian Heimes0a8143f2007-12-18 23:22:54 +00002786- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002787 and INF. float("nan"), float("inf") and float("-inf") now work on
2788 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002789
Georg Brandl3ee81df2008-05-17 18:14:43 +00002790- Compiler now generates simpler and faster code for dictionary
2791 literals. The oparg for BUILD_MAP now indicates an estimated
2792 dictionary size. There is a new opcode, STORE_MAP, for adding
2793 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002822- Patch #1739468: Directories and zipfiles containing a __main__.py
2823 file can now be directly executed by passing their name to the
2824 interpreter. The directory/zipfile is automatically inserted as the
2825 first entry in sys.path.

2836
Georg Brandl3ee81df2008-05-17 18:14:43 +00002837- The enumerate() builtin function is no longer bounded to sequences
2838 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2839 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002840
Georg Brandl3ee81df2008-05-17 18:14:43 +00002841- Issue #1686386: Tuple's tp_repr did not take into account the
2842 possibility of having a self-referential tuple, which is possible
2843 from C code. Nor did object's tp_str consider that a type's tp_str
2844 could do something that could lead to an inifinite recursion.
2845 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2846 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002847
Georg Brandl3ee81df2008-05-17 18:14:43 +00002848- Issue #1164: It was possible to trigger deadlock when using the
2849 'print' statement to write to a file since the GIL was not released
2850 as needed. Now PyObject_Print() does the right thing along with
2851 various tp_print implementations of the built-in types and those in
2852 the collections module.

2856 allowed.

Brett Cannon1e534b52007-09-07 04:18:30 +00002861- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002862 PyObject_Call() never calling back out to Python code to trigger
2863 recursion depth updates/checks. Required the creation of a static
2864 RuntimeError instance in case normalizing an exception put the
2865 recursion check value past its limit. Fixes crashers
2866 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00002881- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002882 __*__ attributes. (Some already existed, e.g., __doc__ and
2883 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002884
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002885- Add -3 option to the interpreter to warn about features that are
2886 deprecated and will be changed/removed in Python 3.0.
2887
Georg Brandl2134e752007-05-21 20:34:16 +00002888- Patch #1686487: you can now pass any mapping after '**' in function
2889 calls.
2890
Collin Winter62903052007-05-18 23:11:24 +00002891- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002892 "except E as target:". This is to provide forwards compatibility
2893 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002894
Brett Cannon229cee22007-05-05 01:34:02 +00002895- Deprecate BaseException.message as per PEP 352.
2896
Georg Brandl3ee81df2008-05-17 18:14:43 +00002897- Issue #1303614: don't expose object's __dict__ when the dict is

2899
Vinay Sajip8549ce32007-05-06 17:53:37 +00002900- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002901 setting a plain string, ie don't expand to single letter identifiers.
2902
Raymond Hettinger13936692007-04-11 18:40:58 +00002903- Request #1191699: Slices can now be pickled.
2904
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002905- Request #1193128: str.translate() now allows a None argument for
2906 translations that only remove characters without re-mapping the
2907 remaining characters.
2908
Georg Brandl5cb76c12007-03-21 09:00:39 +00002909- Patch #1682205: a TypeError while unpacking an iterable is no longer
2910 masked by a generic one with the message "unpack non-sequence".
2911
Neal Norwitzaa754b72007-03-21 06:39:48 +00002912- Remove unused file Python/fmod.c.
2913
Guido van Rossum143b5642007-03-23 04:58:42 +00002914- Bug #1683368: The object.__init__() and object.__new__() methods are
2915 now stricter in rejecting excess arguments. The only time when
2916 either allows excess arguments is when it is not overridden and the
2917 other one is. For backwards compatibility, when both are
2918 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002919 warning later). Also, type.__init__() insists on the same signature
2920 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002921
Georg Brandl3ee81df2008-05-17 18:14:43 +00002922- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2923 object to complex using its __complex__() method before falling back
2924 to the __float__() method. Therefore, the functions in the cmath
2925 module now can operate on objects that define a __complex__()
2926 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002927
Georg Brandl3ee81df2008-05-17 18:14:43 +00002928- Patch #1623563: allow __class__ assignment for classes with
2929 __slots__. The old and the new class are still required to have the
2930 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002931

2936 ``object.__reduce_ex__()`` is called with an object that is faking
2937 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002938
Georg Brandl3ee81df2008-05-17 18:14:43 +00002939- Patch #1680015: Don't modify __slots__ tuple if it contains an

2943
Georg Brandl7b9c5552007-03-12 14:30:05 +00002944- Bug #1678647: write a newline after printing an exception in any
2945 case, even when converting the value to a string failed.
2946
Georg Brandl871f1bc2007-03-12 13:17:36 +00002947- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002948 its argument, if it exists. If not, it will work like before. This
2949 allows customizing the output of dir() in the presence of a
2950 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002951
Collin Winter276887b2007-03-12 16:11:39 +00002952- Patch #922167: Python no longer segfaults when faced with infinitely
2953 self-recursive reload() calls (as reported by bug #742342).
2954
Georg Brandl3ee81df2008-05-17 18:14:43 +00002955- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00002958- Patch #1491866: change the complex() constructor to allow
2959 parthensized forms. This means complex(repr(x)) now works instead of
2960 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002961
Georg Brandlaa2321b2007-03-07 00:40:28 +00002962- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002963 makes the filenames the warning module prints much more sensible
2964 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002965
Georg Brandl49aafc92007-03-07 00:34:46 +00002966- Variant of patch #697613: don't exit the interpreter on a SystemExit
2967 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002968 variable is given, but break into the interactive interpreter just
2969 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00002976
Georg Brandl0fca97a2007-03-05 22:28:08 +00002977- Patch #1674228: when assigning a slice (old-style), check for the
2978 sq_ass_slice instead of the sq_slice slot.
2979
Georg Brandl3ee81df2008-05-17 18:14:43 +00002980- When printing an unraisable error, don't print exceptions. before
2981 the name. This duplicates the behavior whening normally printing
2982 exceptions.

Georg Brandl92a6bae2007-03-13 17:43:32 +00003549- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003550 are set for invalid interpolation sequences that would lead to

3610 -- the failure just occurred later, with a more cumbersome
3611 exception.

3895 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003896
Georg Brandl3ee81df2008-05-17 18:14:43 +00003897- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003898 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00003900 does not claim to support starttls. Adds the
3901 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00004000 time so that opening a database previously created with the DB_DUP
4001 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4002 opens. Specifically: dictionary assignment to a DB object will
4003 replace all values for a given key when the database allows
4004 duplicate values. DB users should use DB.put(k, v) when they want
4005 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004006

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004284- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00004285 periodic threadstate and signal checking in tight loops. By
4286 default, this option is turned-off. It should only be enabled in
4287 debugged, performance critical applications.

4338-----
4339
Georg Brandl3ee81df2008-05-17 18:14:43 +00004340- Unified naming convention for free lists and their limits. All free
4341 lists in Object/ are named ``free_list``, the counter ``numfree``
4342 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4343 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004344
Georg Brandl3ee81df2008-05-17 18:14:43 +00004345- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4346 to ``PyTuple_SetItem``, it can be used to populate a brand new
4347 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004348

4358 ``PyFloat_GetInfo()`` to the float API.
4359
Georg Brandl3ee81df2008-05-17 18:14:43 +00004360- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4361 of w# format code incorrectly truncated the length to an int, even
4362 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4363 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004364
Georg Brandl3ee81df2008-05-17 18:14:43 +00004365- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4383- Fix some leftovers from the conversion from int to Py_ssize_t
4384 (relevant to strings and sequences of more than 2**31 items).
4385
4386- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4387 outside of pystate.c and should not be necessary.
4388
Georg Brandl3ee81df2008-05-17 18:14:43 +00004389- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4390 absolute imports. In earlier versions they might have used relative
4391 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004392
Georg Brandl3ee81df2008-05-17 18:14:43 +00004393- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4394 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004395
Georg Brandl3ee81df2008-05-17 18:14:43 +00004396- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004421- Removed the macfs module. It had been deprecated since Python 2.5.
4422 This lead to the deprecation of macostools.touched() as it relied
4423 solely on macfs and was a no-op under OS X.
