12Core and Builtins
13-----------------
14
Benjamin Peterson753d1622009-07-02 18:16:45 +000015- Issue #4618: When unicode arguments are passed to print(), the default
16 separator and end should be unicode also.
17
Benjamin Peterson1bf47652009-07-02 17:06:17 +000018- Issue #6119: Fixed a incorrect Py3k warning about order comparisons of builtin
19 functions and methods.
20
Mark Dickinson2f865b92009-06-30 15:32:30 +000021- Issue #6347: Include inttypes.h as well as stdint.h in pyport.h.
22 This fixes a build failure on HP-UX: int32_t and uint32_t are
23 defined in inttypes.h instead of stdint.h on that platform.
24
Hirokazu Yamamotoa3c56092009-06-28 10:23:00 +000025- Issue #4856: Remove checks for win NT.
26
Amaury Forgeot d'Arc595f7a52009-06-25 22:29:29 +000027- Issue #2016: Fixed a crash in a corner case where the dictionary of keyword
28 arguments could be modified during the function call setup.
29
Amaury Forgeot d'Arc14fc6732009-06-23 21:09:09 +000030- Removed the ipaddr module.
31
Raymond Hettinger62641e92009-06-23 20:59:43 +000032- Issue #6329: Fixed iteration for memoryview objects (it was being blocked
33 because it wasn't recognized as a sequence).
34
Benjamin Peterson08a0bbc2009-06-16 00:29:31 +000035- Issue #6289: Encoding errors from compile() were being masked.
36
Benjamin Petersona72be3b2009-06-13 20:23:33 +000037- When no module is given in a relative import, the module field of the
38 ImportFrom AST node is now None instead of an empty string.
39
Benjamin Peterson565e1b62009-06-13 03:46:30 +000040- Assignment to None using import statements now raises a SyntaxError.
41
Benjamin Peterson4afbba32009-06-13 01:40:00 +000042- In the slice AST type, the step field will always be None if a step expression
43 is not specified.
44
Amaury Forgeot d'Arcb02ceda2009-06-01 20:53:18 +000045- Issue #4547: When debugging a very large function, it was not always
46 possible to update the lineno attribute of the current frame.
47
Antoine Pitrou46dbe272009-05-30 21:27:00 +000048- Issue #5330: C functions called with keyword arguments were not reported by
49 the various profiling modules (profile, cProfile). Patch by Hagen Fürstenau.

Raymond Hettinger578a2282009-05-29 04:58:52 +000051- Issue #5982: staticmethod and classmethod now expose the wrapped
52 function with __func__.
53
Raymond Hettinger822b87f2009-05-29 01:46:48 +000054- Added support for multiple context managers in the same with-statement.
55 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl944f6842009-05-25 21:02:56 +000056
Benjamin Peterson1880d8b2009-05-25 13:13:44 +000057- Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with
58 statement and correctly lookup the __enter__ and __exit__ special methods.
59
Mark Dickinsona4e0efa2009-05-20 18:43:07 +000060- Issue #5829: complex("1e500") no longer raises OverflowError. This
61 makes it consistent with float("1e500") and interpretation of real
62 and imaginary literals.
63
Hirokazu Yamamotoa4f90182009-05-17 02:58:36 +000064- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
65
Benjamin Peterson0c3b4c62009-05-16 23:34:19 +000066- __instancecheck__ and __subclasscheck__ are now completely ignored on classic
67 classes and instances.
Benjamin Petersoneb9fb2c2009-05-16 22:46:11 +000068
R. David Murray525cffc2009-05-13 13:07:14 +000069- Issue #5994: the marshal module now has docstrings.
70
Mark Dickinsonb1d45852009-05-11 15:33:08 +000071- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
72 (1) inf and nan strings with trailing whitespace were incorrectly
73 rejected; (2) parsing of strings representing infinities and nans
74 was locale aware; and (3) the interpretation of fromhex('-nan')
75 didn't match that of float('-nan').
76
Eric Smitha985a3a2009-05-05 18:26:08 +000077- Issue #5920: For float.__format__, change the behavior with the
78 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
79 to be like 'g' but with at least one decimal point and with a
80 default precision of 12. Previously, the behavior the same but with
81 a default precision of 6. This more closely matches str(), and
82 reduces surprises when adding alignment flags to the empty
83 presentation type. This also affects the new complex.__format__ in
84 the same way.
85
R. David Murray7ba8e1c2009-05-04 22:16:24 +000086- Issue #5890: in subclasses of 'property' the __doc__ attribute was
87 shadowed by classtype's, even if it was None. property now
88 inserts the __doc__ into the subclass instance __dict__.
89
Antoine Pitrou653dece2009-05-04 18:32:32 +000090- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
91 sequences. Patch by Nick Barnes and Victor Stinner.
92
Vinay Sajipf9b01fe2009-05-09 12:07:17 +000093- Issue #1588: Add complex.__format__. For example,
Eric Smith9139cc62009-04-30 00:58:58 +000094 format(complex(1, 2./3), '.5') now produces a sensible result.
95
Mark Dickinson92fcc9c2009-04-29 20:41:00 +000096- Issue #5864: Fix empty format code formatting for floats so that it
97 never gives more than the requested number of significant digits.
98
Eric Smithcac7af62009-04-27 19:04:37 +000099- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
100 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
101
Martin v. Löwis99f27792009-04-26 00:53:18 +0000102- Issue #4971: Fix titlecase for characters that are their own
103 titlecase, but not their own uppercase.
104
Eric Smith068f0652009-04-25 21:40:15 +0000105- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
106 _PyOS_double_to_string or PyOS_double_to_string.
107
Benjamin Peterson5083dc52009-04-25 00:41:22 +0000108- Issue #5283: Setting __class__ in __del__ caused a segfault.
109
Mark Dickinson95bc9802009-04-24 12:46:53 +0000110- Issue #5816: complex(repr(z)) now recovers z exactly, even when
111 z involves nans, infs or negative zeros.
112
Eric Smithaca19e62009-04-22 13:29:05 +0000113- Implement PEP 378, Format Specifier for Thousands Separator, for
114 floats, ints, and longs.
115
116- Issue #5515: 'n' formatting for ints, longs, and floats handles
117 leading zero formatting poorly.
118
119- Issue #5772: For float.__format__, don't add a trailing ".0" if
120 we're using no type code and we have an exponent.
121
Mark Dickinson6736cf82009-04-20 21:13:33 +0000122- Issue #3166: Make long -> float (and int -> float) conversions
123 correctly rounded.
124
Benjamin Petersond4d400c2009-04-18 20:12:47 +0000125- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
126 some builtin types.
127
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000128- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000129 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000130
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000131- Issue #5759: float() didn't call __float__ on str subclasses.
132
Georg Brandl3c4a5462009-04-12 12:08:12 +0000133- Issue #5704: the "-3" command-line option now implies "-t".
134
R. David Murray0374a822009-04-09 21:54:50 +0000135- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
136 its clarity and its speed.
137
Antoine Pitrou789be0c2009-04-02 21:18:34 +0000138- Issue #2396: the memoryview object was backported from Python 3.1.

144
Ronald Oussorene0154ed2009-03-30 23:10:35 +0000145- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
146 the end sys.path, for compatibility with the system install of Python.
147
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000148- Issue #4688: Add a heuristic so that tuples and dicts containing only
149 untrackable objects are not tracked by the garbage collector. This can
150 reduce the size of collections and therefore the garbage collection overhead
151 on long-running programs, depending on their particular use of datatypes.
152
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000153- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
154 improve its performance. Long divisions and remainder operations
155 are now between 50% and 150% faster.
156
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000157- Issue #4258: Make it possible to use base 2**30 instead of base
158 2**15 for the internal representation of integers, for performance
159 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
160 --enable-big-digits option to configure, which overrides the
161 default. Add sys.long_info structseq to provide information about
162 the internal format.
163
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000164- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
165 result traceback.__members__ no longer exists.)
166
Mark Dickinson6b265f12009-03-18 16:07:26 +0000167- Issue #4474: PyUnicode_FromWideChar now converts characters outside
168 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
169 and sizeof(Py_UNICODE) == 2.
170
Eric Smith6f42edb2009-03-14 11:57:26 +0000171- Issue #5237: Allow auto-numbered fields in str.format(). For
172 example: '{} {}'.format(1, 2) == '1 2'.
173
Brett Cannon6c4cff02009-03-11 04:51:06 +0000174- Issue #3652: Make the 'line' argument for warnings.showwarning() a
175 requirement. Means the DeprecationWarning from Python 2.6 can go away.
176
Eric Smithe9fb6862009-02-20 14:02:36 +0000177- Issue #5247: Improve error message when unknown format codes are
178 used when using str.format() with str, unicode, long, int, and
179 float arguments.
180
Raymond Hettinger08259e82009-02-18 23:10:19 +0000181- Running Python with the -3 option now also warns about classic division
182 for ints and longs.
183
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000184- Issue #5260: Long integers now consume less memory: average
185 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
186 on a 64-bit system.
187
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000188- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
189 rotating the object pointer by 4 bits to the right.
190
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000191- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
192 it now forces its argument to double before testing for infinity.
193
Benjamin Petersone18ef192009-01-20 14:21:16 +0000194- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
195
Georg Brandl29c6a282009-04-05 20:23:13 +0000196- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000197 were suppressing all exceptions. These include list(), filter(), map(),
198 zip(), and bytearray().
199
Benjamin Peterson596d3062009-01-19 15:42:23 +0000200- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

207
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000208- Issue #4935: The overflow checking code in the expandtabs() method common
209 to str, bytes and bytearray could be optimized away by the compiler, letting
210 the interpreter segfault instead of raising an error.
211
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000212- Issue #3720: Fix a crash when an iterator modifies its class and removes its
213 __next__ method.

218
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000219- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
220 collecting the oldest generation) so that allocating lots of objects without
221 destroying them does not show quadratic performance. Based on a proposal by
222 Martin von Löwis at
223 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
224
Martin v. Löwisb90304a2009-01-07 18:40:40 +0000225- Issue #4850: Change COUNT_ALLOCS variables to Py_ssize_t.
226
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000227- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
228 an existing .py counterpart, override the co_filename attributes of all
229 code objects if the original filename is obsolete (which can happen if the
230 file has been renamed, moved, or if it is accessed through different paths).
231 Patch by Ziga Seilnacht and Jean-Paul Calderone.
232
Martin v. Löwis5344c992009-01-02 20:32:55 +0000233- Issue #4075: Use OutputDebugStringW in Py_FatalError.
234
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000235- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open

242 where the tp_hash and tp_dict slots are both NULL.
243
Benjamin Peterson7af65562008-12-29 17:56:58 +0000244- Issue #4764: With io.open, IOError.filename is set when trying to open a
245 directory on POSIX systems.

254 fail.
255
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000256- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
257 print elapsed times, not only when some objects are uncollectable /
258 unreachable. Original patch by Neil Schemenauer.
259
Mark Dickinson1a707982008-12-17 16:14:37 +0000260- Issue #3439: Add a bit_length method to int and long.

269 exceptions.
270
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000271- Issue #4445: Replace "sizeof(PyStringObject)" with
272 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
273 str instances. On a typical machine this saves 3 bytes of memory
274 (on average) per string allocation.
275
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000276- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

285
Vinay Sajip213faca2008-12-03 23:22:58 +0000286- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000287 method on file objects with closefd=False. The file descriptor is still
288 kept open but the file object behaves like a closed file. The ``FileIO``
289 object also got a new readonly attribute ``closefd``.
290
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000291- Issue #4348: Some bytearray methods returned that didn't cause any change to

301 exec statement.
302
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000303- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``

1174 for the integer formats ('bBhHiIlLqQ'). In the following, '*'
1175 represents any of '=', '<', '>'.
1176
1177 - Packing a float now always gives a Deprecation Warning.
1178 Previously it only warned for 'I', 'L', '*B', '*H', '*I', '*L'.
1179
1180 - If x is not an int, long or float, then packing x will always
1181 result in struct.error. Previously an x with an __int__ method
1182 could be packed by 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h'
1183 ,'*i', '*l', and an x with a __long__ method could be packed by
1184 'q', 'Q', '*q', '*Q'; for x with neither __int__ nor __long__,

1336
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001337- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1338 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1339 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1340 ``printf`` function, whereas PyString_FromFormat has an independent
1341 implementation and uses "%zd" on all platforms for size_t values.
1342 This makes a difference on win64, where ``printf`` needs "%Id" to display
1343 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001345- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001360 was correctly parsed but parsing of subsequent arguments failed.
1361
Vinay Sajip35e3b032008-09-01 14:33:59 +00001362- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001363 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1364 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1365 when given a tuple of classes as second argument, were looking up
1366 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1367 type object.
1368
Neal Norwitz18aa3882008-08-24 05:04:52 +00001369- Fix crashes on memory allocation failure found with failmalloc.

1435 path to the Python binary.
1436
Brett Cannon1eaf0742008-09-02 01:25:16 +00001437- Issue 3602: Moved test.test_support.catch_warning() to
1438 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1439 for catch_warnings() also led to an improvement in the raising of a
1440 DeprecationWarning related to warnings.warn_explicit().
1441
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001442- The deprecation warnings for the old camelCase threading API were removed.

1463 _check_logger_class from multiprocessing.
1464
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001465- Issue #2975: When compiling several extension modules with Visual Studio 2008
1466 from the same python interpreter, some environment variables would grow
1467 without limit.
1468
Benjamin Peterson37346b22008-08-23 20:27:43 +00001469- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

1476
Gerhard Häringe6872eb2008-09-12 22:33:22 +00001477- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

1485 wrapper for warnings.catch_warnings() that makes it easier to check
1486 that expected warning messages are being reported.
1487

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001506What's New in Python 2.6 beta 3?
1507================================
1508
Barry Warsaw07a4a382008-08-21 01:15:08 +00001509*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001510
1511Core and Builtins
1512-----------------
1513
Guido van Rossumf8402962008-08-20 15:01:50 +00001514- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1515 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1516 extensions do not automatically benefit from the class attribute
1517 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1518 to their tp_flags field if they care. This is a backwards
1519 compatibility feature; in 3.0, all types will use the cache by
1520 default.
1521
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001522- Keyword arguments can now follow starred arguments. (``f(a, *args,
1523 keyword=23)`` is now valid syntax.)
1524
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001525- ctypes function pointers that are COM methods have a boolean True
1526 value again.
1527
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001528- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1529 by denying s# to parse objects that have a releasebuffer procedure,
1530 and introducing s*.
1531
Georg Brandl1e13ea92008-08-11 09:07:59 +00001532- Issue #3537: Fix an assertion failure when an empty but presized dict
1533 object was stored in the freelist.
1534
Mark Dickinsonb6467572008-08-04 21:30:09 +00001535- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1536 ValueError consistently across platforms.
1537
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001538- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1539 (64bit Unix, for example), unichr() would truncate its argument and return
1540 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1541
Neal Norwitze7d8be82008-07-31 17:17:14 +00001542- Apply security patches from Apple.
1543
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001544- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1545 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1546
Antoine Pitrou92f82162008-07-25 22:22:08 +00001547- Issue #1819: function calls with several named parameters are now on
1548 average 35% faster (as measured by pybench).
1549
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001550- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1551 the python debugger steps into a class statement: the free variables (local
1552 variables defined in an outer scope) would be deleted from the outer scope.
1553
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001554- Issue #2620: Overflow checking when allocating or reallocating memory
1555 was not always being done properly in some python types and extension
1556 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1557 all been updated to perform better checks and places in the code that
1558 would previously leak memory on the error path when such an allocation
1559 failed have been fixed.
1560
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001561Library
1562-------
1563
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001564- Issue #3612: Added some missing basic types in ctypes.wintypes.
1565
Benjamin Petersone977ad42008-08-20 01:42:01 +00001566- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1567 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1568
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001569- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1570 version reported by these tools does not necessarily follow the python
1571 version numbering scheme, so the module is less strict when parsing it.
1572
Nick Coghlanf70385a2008-08-18 12:42:46 +00001573- Issue #2235: Added Py3k warnings for types which will become unhashable
1574 under the stricter __hash__ inheritance rules in 3.0. Several types
1575 which did not meet the rules for hash invariants and were already
1576 unhashable in 3.0 have now been explicitly flagged as unhashable in
1577 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1578 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1579
Brett Cannon88f801d2008-08-18 00:46:22 +00001580- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

1584
Brett Cannon46225e72008-08-18 00:36:52 +00001585- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001587- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1588
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001589- Issue #3575: Incremental decoder's decode function now takes bytearray
1590 by using 's*' instead of 't#'.
1591
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001592- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001593 fails unicode conversion on 2nd parameter. (windows only)
1594
Facundo Batista94f243a2008-08-17 03:38:39 +00001595- Issue 2464. urllib2 now supports a malformation in the URL received
1596 in a redirect.
1597
Brett Cannonabe423e2008-08-16 21:47:07 +00001598- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001599 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001600
Facundo Batistaeb90b782008-08-16 14:44:07 +00001601- Issue #2776: fixed small issue when handling an URL with double slash
1602 after a 302 response in the case of not going through a proxy.
1603
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001604- Issue #2676: in the email package, content-type parsing was hanging on
1605 pathological input because of quadratic or exponential behaviour of a
1606 regular expression.
1607
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001608- Issue #3476: binary buffered reading through the new "io" library is now
1609 thread-safe.
1610
Brett Cannonbf3157b2008-08-14 05:00:03 +00001611- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1612 since mimetools itself is deprecated. Because modules are cached, all
1613 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1614
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001615- Issue #3134: shutil referenced undefined WindowsError symbol.
1616
Robert Schuppenies14646332008-08-10 11:01:53 +00001617- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1618 menu entries were not deleted.
1619
Brett Cannon83e81842008-08-09 23:30:55 +00001620- Copied the implementation of reduce() to _functools.reduce() to have a
1621 version that did not raise a DeprecationWarning under -3.
1622
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001623- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1624 a MemoryError rather than silently stop the iteration.
1625
Guido van Rossum59ce9012008-08-09 14:55:34 +00001626- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1627 to _sre.compile() will now be rejected. This should not affect anybody
1628 since the re.compile() function never generates invalid re-bytecode.
1629
Skip Montanaroa032bf42008-08-08 22:52:51 +00001630- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1631 upon first access it can be automatically initialized from the csv file if
1632 it wasn't initialized during instantiation.
1633
Brett Cannon3aa2a492008-08-06 22:28:09 +00001634- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1635 the reload() built-in has been removed.
1636
Brett Cannon7e30b672008-08-04 21:52:25 +00001637- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001638 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001649 asking for a specific length. This problem only affected files opened
1650 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001651

1676 file name rather than a ZipInfo instance, so files are extracted with
1677 mode 0600 rather than 000 under Unix.
1678
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001679- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

1695 coverage of the lookup process for special methods. The disclaimers
1696 regarding lack of coverage of new-style classes have also been
1697 removed, since the coverage is now fairly reasonable.

1707
Georg Brandl3e483f62008-07-16 22:57:41 +00001708- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1709 its methods now allow for items objects that can be converted to
1710 an integer using operator.index().
1711
Mark Dickinson64b7e502008-07-16 09:40:03 +00001712- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1713 produced a ValueError instead of giving the correct float.
1714
Eric Smitha5fa5a22008-07-16 00:11:49 +00001715- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1716 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1717
Mark Dickinson7103aa42008-07-15 19:08:33 +00001718- Issue #3008: the float type has a new instance method 'float.hex'

1720 numbers to and from hexadecimal strings, respectively.
1721
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001722- Issue #2235: __hash__ is once again inherited by default. To allow
1723 collections.Hashable to remain meaningful in the presence of the

Nick Coghlanb028f502008-07-13 14:52:36 +00001729- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1730 the parent module cannot be found while performing an absolute import.
1731 This means that an incorrectly defined __package__ attribute will
1732 now only prevent relative imports in that module rather than causing
1733 all imports from that module to fail.

Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001747- Issue #3004: Minor change to slice.indices(): the start and stop
1748 arguments are now treated identically, making the behaviour easier
1749 to describe and understand. For example, slice(None, -10,
1750 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1751 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1752 10, -1).

2255 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002268- Issue #1631171: Re-implement the 'warnings' module in C (the
2269 original Python code has been kept as backup). This will allow for
2270 using the 'warning's machinery in such places as the parser where
2271 use of pure Python code is not possible. Both the ``showarning()``
2272 and ``formatwarning()`` gain an optional 'line' argument which is
2273 not called by default for backwards-compatibility reasons. Setting
2274 ``warnings.showwarning()`` to an implementation that lacks support
2275 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002338- Issue #2550: The approach used by client/server code for obtaining
2339 ports to listen on in network-oriented tests has been refined in an
2340 effort to facilitate running multiple instances of the entire
2341 regression test suite in parallel without issue.
2342 test_support.bind_port() has been fixed such that it will always
2343 return a unique port -- which wasn't always the case with the
2344 previous implementation, especially if socket options had been set
2345 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2346 new implementation of bind_port() will actually raise an exception
2347 if it is passed an AF_INET/SOCK_STREAM socket with either the
2348 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2349 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2350 the socket it's been passed. This currently only applies to
2351 Windows. This option prevents any other sockets from binding to the
2352 host/port we've bound to, thus removing the possibility of the
2353 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2354 when a second SOCK_STREAM socket binds and accepts to a host/port
2355 that's already been bound by another socket. The optional preferred
2356 port parameter to bind_port() has been removed. Under no
2357 circumstances should tests be hard coding ports!
2358
2359 test_support.find_unused_port() has also been introduced, which will
2360 pass a temporary socket object to bind_port() in order to obtain an
2361 unused port. The temporary socket object is then closed and
2362 deleted, and the port is returned. This method should only be used
2363 for obtaining an unused port in order to pass to an external program
2364 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2365 a parameter to a server-oriented class that doesn't give you direct
2366 access to the underlying socket used.
2367
2368 Finally, test_support.HOST has been introduced, which should be used
2369 for the host argument of any relevant socket calls (i.e. bind and
2370 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002371
2372 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002373 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002374 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2375 test_asynchat and test_socket_ssl.
2376
Georg Brandl3ee81df2008-05-17 18:14:43 +00002377 It is now possible for multiple instances of the regression test
2378 suite to run in parallel without issue.

2645-----------------
2646
Fred Drakea8ee94b2008-03-01 02:45:07 +00002647- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002648 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002649
Georg Brandlad61bc82008-02-23 15:11:18 +00002650- Issue #2067: file.__exit__() now calls subclasses' close() method.
2651
2652- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002653
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002654- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002655 issue 215555 for a discussion.
2656
Eric Smitha73fbe72008-02-23 03:09:44 +00002657- Added the future_builtins module, which contains hex() and oct().
2658 These are the PEP 3127 version of these functions, designed to be
2659 compatible with the hex() and oct() builtins from Python 3.0. They
2660 differ slightly in their output formats from the existing, unchanged
2661 Python 2.6 builtins. The expected usage of the future_builtins
2662 module is:
2663 from future_builtins import hex, oct
2664
Eric Smith7ef40bf2008-02-20 23:34:22 +00002665- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2666 exponents for exponents with absolute value < 100. Follows C99
2667 standard. This is a change on Windows, which would use 3 digits.
2668 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2669 so that any alterations it does to the resulting string will be
2670 available in stringlib/formatter.h (for float.__format__).
2671
Eric Smith5a3c1352008-02-19 13:21:56 +00002672- Implemented PEP 3101, Advanced String Formatting. This adds a new
2673 builtin format(); a format() method for str and unicode; a
2674 __format__() method to object, str, unicode, int, long, float, and
2675 datetime; the class string.Formatter; and the C API
2676 PyObject_Format().
2677
Georg Brandl3ee81df2008-05-17 18:14:43 +00002678- Fixed several potential crashes, all caused by specially crafted
2679 __del__ methods exploiting objects in temporarily inconsistent
2680 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002681
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002682- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002683 prevent a possible crash: an Abstract Base Class would try to access
2684 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002685
Georg Brandl3ee81df2008-05-17 18:14:43 +00002686- Fixed repr() and str() of complex numbers with infinity or nan as
2687 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002688
Georg Brandl3ee81df2008-05-17 18:14:43 +00002689- Clear all free lists during a gc.collect() of the highest generation
2690 in order to allow pymalloc to free more arenas. Python may give back
2691 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002692
Georg Brandl3ee81df2008-05-17 18:14:43 +00002693- Issue #2045: Fix an infinite recursion triggered when printing a
2694 subclass of collections.defaultdict, if its default_factory is set
2695 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002696
Christian Heimesf75dbef2008-02-08 00:11:31 +00002697- Fixed a minor memory leak in dictobject.c. The content of the free
2698 list was not freed on interpreter shutdown.
2699
Georg Brandl3ee81df2008-05-17 18:14:43 +00002700- Limit free list of method and builtin function objects to 256
2701 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002702
Georg Brandl3ee81df2008-05-17 18:14:43 +00002703- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2704 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002705 to compact the internal free lists of pre-allocted ints and floats.
2706
Georg Brandl3ee81df2008-05-17 18:14:43 +00002707- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2708 calls. Python expected the return type int but the fork familie
2709 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002710
Georg Brandl3ee81df2008-05-17 18:14:43 +00002711- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2712 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002713
Georg Brandl3ee81df2008-05-17 18:14:43 +00002714- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2715 with the collections.Sequence API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002720- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2721 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002722
Georg Brandl3ee81df2008-05-17 18:14:43 +00002723- Patch #1473257: generator objects gain a gi_code attribute. This is
2724 the same object as the func_code attribute of the function that
2725 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002726
Georg Brandl3ee81df2008-05-17 18:14:43 +00002727- Issue #1920: "while 0" statements were completely removed by the
2728 compiler, even in the presence of an "else" clause, which is
2729 supposed to be run when the condition is false. Now the compiler
2730 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002731
Guido van Rossumeead05f2008-01-24 18:21:02 +00002732- A few crashers fixed: weakref_in_del.py (issue #1377858);
2733 loosing_dict_ref.py (issue #1303614, test67.py);
2734 borrowed_ref_[34].py (not in tracker).
2735
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002736- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002737 suppressed while an extension is loaded by calling SetErrorMode in
2738 dynload_win.c. The error is still reported properly.
2739
Georg Brandl3ee81df2008-05-17 18:14:43 +00002740- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002741 several extension methods and modules do not work without unicode
2742 support.
2743
Georg Brandl26543b12008-01-21 18:36:51 +00002744- Issue #1882: when compiling code from a string, encoding cookies in the
2745 second line of code were not always recognized correctly.
2746
Georg Brandl14404b62008-01-19 19:27:05 +00002747- Issue #1679: "0x" was taken as a valid integer literal.
2748
Georg Brandl6caad7d2008-01-26 14:19:22 +00002749- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002750 added.
2751
Christian Heimesc94e2b52008-01-14 04:13:37 +00002752- sys.float_info / PyFloat_GetInfo: The floating point information
2753 object was converted from a dict to a specialized structseq object.
2754
Georg Brandl3ee81df2008-05-17 18:14:43 +00002755- Patch #1816: Added sys.flags structseq. It exposes the status of
2756 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002757
Georg Brandl3ee81df2008-05-17 18:14:43 +00002758- Objects/structseq.c: Implemented new structseq representation. The
2759 patch makes structseqs (e.g. the return value of os.stat) more
2760 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002761
Georg Brandl3ee81df2008-05-17 18:14:43 +00002762- Patch #1700288: added a type attribute cache that caches method

2771 envvar and sys.dont_write_bytecode attribute. All these can be set
2772 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002773
Georg Brandl3ee81df2008-05-17 18:14:43 +00002774- Improve some exception messages when Windows fails to load an
2775 extension module. Now we get for example '%1 is not a valid Win32
2776 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002777

Christian Heimes0a8143f2007-12-18 23:22:54 +00002783- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002784 and INF. float("nan"), float("inf") and float("-inf") now work on
2785 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002786
Georg Brandl3ee81df2008-05-17 18:14:43 +00002787- Compiler now generates simpler and faster code for dictionary
2788 literals. The oparg for BUILD_MAP now indicates an estimated
2789 dictionary size. There is a new opcode, STORE_MAP, for adding
2790 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002819- Patch #1739468: Directories and zipfiles containing a __main__.py
2820 file can now be directly executed by passing their name to the
2821 interpreter. The directory/zipfile is automatically inserted as the
2822 first entry in sys.path.

2833
Georg Brandl3ee81df2008-05-17 18:14:43 +00002834- The enumerate() builtin function is no longer bounded to sequences
2835 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2836 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002837
Georg Brandl3ee81df2008-05-17 18:14:43 +00002838- Issue #1686386: Tuple's tp_repr did not take into account the
2839 possibility of having a self-referential tuple, which is possible
2840 from C code. Nor did object's tp_str consider that a type's tp_str
2841 could do something that could lead to an inifinite recursion.
2842 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2843 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002844
Georg Brandl3ee81df2008-05-17 18:14:43 +00002845- Issue #1164: It was possible to trigger deadlock when using the
2846 'print' statement to write to a file since the GIL was not released
2847 as needed. Now PyObject_Print() does the right thing along with
2848 various tp_print implementations of the built-in types and those in
2849 the collections module.

2853 allowed.

Brett Cannon1e534b52007-09-07 04:18:30 +00002858- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002859 PyObject_Call() never calling back out to Python code to trigger
2860 recursion depth updates/checks. Required the creation of a static
2861 RuntimeError instance in case normalizing an exception put the
2862 recursion check value past its limit. Fixes crashers
2863 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00002878- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002879 __*__ attributes. (Some already existed, e.g., __doc__ and
2880 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002881
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002882- Add -3 option to the interpreter to warn about features that are
2883 deprecated and will be changed/removed in Python 3.0.
2884

2886 calls.
2887
Collin Winter62903052007-05-18 23:11:24 +00002888- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002889 "except E as target:". This is to provide forwards compatibility
2890 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002891
Brett Cannon229cee22007-05-05 01:34:02 +00002892- Deprecate BaseException.message as per PEP 352.
2893
Georg Brandl3ee81df2008-05-17 18:14:43 +00002894- Issue #1303614: don't expose object's __dict__ when the dict is

2896
Vinay Sajip8549ce32007-05-06 17:53:37 +00002897- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002898 setting a plain string, ie don't expand to single letter identifiers.
2899
Raymond Hettinger13936692007-04-11 18:40:58 +00002900- Request #1191699: Slices can now be pickled.
2901
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002902- Request #1193128: str.translate() now allows a None argument for
2903 translations that only remove characters without re-mapping the
2904 remaining characters.
2905
Georg Brandl5cb76c12007-03-21 09:00:39 +00002906- Patch #1682205: a TypeError while unpacking an iterable is no longer
2907 masked by a generic one with the message "unpack non-sequence".
2908
Neal Norwitzaa754b72007-03-21 06:39:48 +00002909- Remove unused file Python/fmod.c.
2910
Guido van Rossum143b5642007-03-23 04:58:42 +00002911- Bug #1683368: The object.__init__() and object.__new__() methods are
2912 now stricter in rejecting excess arguments. The only time when
2913 either allows excess arguments is when it is not overridden and the
2914 other one is. For backwards compatibility, when both are
2915 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002916 warning later). Also, type.__init__() insists on the same signature
2917 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002918
Georg Brandl3ee81df2008-05-17 18:14:43 +00002919- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2920 object to complex using its __complex__() method before falling back
2921 to the __float__() method. Therefore, the functions in the cmath
2922 module now can operate on objects that define a __complex__()
2923 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002924
Georg Brandl3ee81df2008-05-17 18:14:43 +00002925- Patch #1623563: allow __class__ assignment for classes with
2926 __slots__. The old and the new class are still required to have the
2927 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002928

2933 ``object.__reduce_ex__()`` is called with an object that is faking
2934 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002935
Georg Brandl3ee81df2008-05-17 18:14:43 +00002936- Patch #1680015: Don't modify __slots__ tuple if it contains an

2940
Georg Brandl7b9c5552007-03-12 14:30:05 +00002941- Bug #1678647: write a newline after printing an exception in any
2942 case, even when converting the value to a string failed.
2943
Georg Brandl871f1bc2007-03-12 13:17:36 +00002944- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002945 its argument, if it exists. If not, it will work like before. This
2946 allows customizing the output of dir() in the presence of a
2947 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002948
Collin Winter276887b2007-03-12 16:11:39 +00002949- Patch #922167: Python no longer segfaults when faced with infinitely
2950 self-recursive reload() calls (as reported by bug #742342).
2951
Georg Brandl3ee81df2008-05-17 18:14:43 +00002952- Patch #1675981: remove unreachable code from ``type.__new__()``
2953 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002955- Patch #1491866: change the complex() constructor to allow
2956 parthensized forms. This means complex(repr(x)) now works instead of
2957 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002958
Georg Brandlaa2321b2007-03-07 00:40:28 +00002959- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002960 makes the filenames the warning module prints much more sensible
2961 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002962
Georg Brandl49aafc92007-03-07 00:34:46 +00002963- Variant of patch #697613: don't exit the interpreter on a SystemExit
2964 exception if the -i command line option or PYTHONINSPECT environment

Georg Brandl0fca97a2007-03-05 22:28:08 +00002974- Patch #1674228: when assigning a slice (old-style), check for the
2975 sq_ass_slice instead of the sq_slice slot.
2976
Georg Brandl3ee81df2008-05-17 18:14:43 +00002977- When printing an unraisable error, don't print exceptions. before
2978 the name. This duplicates the behavior whening normally printing
2979 exceptions.

Georg Brandl92a6bae2007-03-13 17:43:32 +00003546- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003547 are set for invalid interpolation sequences that would lead to

3607 -- the failure just occurred later, with a more cumbersome
3608 exception.

3891 obtained from the TLS negotiation itself. Patch contributed by Bill
3892 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003893
Georg Brandl3ee81df2008-05-17 18:14:43 +00003894- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003895 that the SMTP.starttls() caller no longer needs to call ehlo()
3896 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003897 does not claim to support starttls. Adds the
3898 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Raymond Hettinger12e94202007-11-07 01:13:09 +00003982

Georg Brandl3ee81df2008-05-17 18:14:43 +00003997 time so that opening a database previously created with the DB_DUP
3998 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3999 opens. Specifically: dictionary assignment to a DB object will
4000 replace all values for a given key when the database allows
4001 duplicate values. DB users should use DB.put(k, v) when they want
4002 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004003

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004281- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00004282 periodic threadstate and signal checking in tight loops. By
4283 default, this option is turned-off. It should only be enabled in
4284 debugged, performance critical applications.
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004285

4335-----
4336
Georg Brandl3ee81df2008-05-17 18:14:43 +00004337- Unified naming convention for free lists and their limits. All free
4338 lists in Object/ are named ``free_list``, the counter ``numfree``
4339 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4340 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004341
Georg Brandl3ee81df2008-05-17 18:14:43 +00004342- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4343 to ``PyTuple_SetItem``, it can be used to populate a brand new
4344 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004345

4353
4354- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4355 ``PyFloat_GetInfo()`` to the float API.
4356
Georg Brandl3ee81df2008-05-17 18:14:43 +00004357- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4358 of w# format code incorrectly truncated the length to an int, even
4359 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4360 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004361
Georg Brandl3ee81df2008-05-17 18:14:43 +00004362- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4380- Fix some leftovers from the conversion from int to Py_ssize_t
4381 (relevant to strings and sequences of more than 2**31 items).
4382
4383- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4384 outside of pystate.c and should not be necessary.
4385
Georg Brandl3ee81df2008-05-17 18:14:43 +00004386- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4387 absolute imports. In earlier versions they might have used relative
4388 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004389
Georg Brandl3ee81df2008-05-17 18:14:43 +00004390- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4391 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004392
Georg Brandl3ee81df2008-05-17 18:14:43 +00004393- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004418- Removed the macfs module. It had been deprecated since Python 2.5.
4419 This lead to the deprecation of macostools.touched() as it relied
4420 solely on macfs and was a no-op under OS X.
