16 sequences. Patch by Nick Barnes and Victor Stinner.
17
Eric Smith9139cc62009-04-30 00:58:58 +000018- Issue #1588: Add complex.__format__. For example,
19 format(complex(1, 2./3), '.5') now produces a sensible result.
20
Mark Dickinson92fcc9c2009-04-29 20:41:00 +000021- Issue #5864: Fix empty format code formatting for floats so that it
22 never gives more than the requested number of significant digits.
23

32
Benjamin Peterson5083dc52009-04-25 00:41:22 +000033- Issue #5283: Setting __class__ in __del__ caused a segfault.
34
Mark Dickinson95bc9802009-04-24 12:46:53 +000035- Issue #5816: complex(repr(z)) now recovers z exactly, even when
36 z involves nans, infs or negative zeros.
37
Eric Smithaca19e62009-04-22 13:29:05 +000038- Implement PEP 378, Format Specifier for Thousands Separator, for
39 floats, ints, and longs.
40
41- Issue #5515: 'n' formatting for ints, longs, and floats handles
42 leading zero formatting poorly.
43
44- Issue #5772: For float.__format__, don't add a trailing ".0" if
45 we're using no type code and we have an exponent.
46
Mark Dickinson6736cf82009-04-20 21:13:33 +000047- Issue #3166: Make long -> float (and int -> float) conversions
48 correctly rounded.
49
Benjamin Petersond4d400c2009-04-18 20:12:47 +000050- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
51 some builtin types.
52
Mark Dickinson1bdf7e92009-04-18 14:59:42 +000053- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +000054 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +000055
Benjamin Peterson99d36f12009-04-15 21:26:36 +000056- Issue #5759: float() didn't call __float__ on str subclasses.

61 its clarity and its speed.
62
Antoine Pitrou789be0c2009-04-02 21:18:34 +000063- Issue #2396: the memoryview object was backported from Python 3.1.
64

69
Ronald Oussorene0154ed2009-03-30 23:10:35 +000070- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
71 the end sys.path, for compatibility with the system install of Python.
72
Antoine Pitrouf8387af2009-03-23 18:41:45 +000073- Issue #4688: Add a heuristic so that tuples and dicts containing only
74 untrackable objects are not tracked by the garbage collector. This can
75 reduce the size of collections and therefore the garbage collection overhead
76 on long-running programs, depending on their particular use of datatypes.
77
Mark Dickinson0b666bf2009-03-23 18:25:13 +000078- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
79 improve its performance. Long divisions and remainder operations
80 are now between 50% and 150% faster.
81
Mark Dickinsonefc82f72009-03-20 15:51:55 +000082- Issue #4258: Make it possible to use base 2**30 instead of base
83 2**15 for the internal representation of integers, for performance
84 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
85 --enable-big-digits option to configure, which overrides the
86 default. Add sys.long_info structseq to provide information about
87 the internal format.
88
Benjamin Peterson6ffe8522009-03-18 20:52:15 +000089- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
90 result traceback.__members__ no longer exists.)
91
Mark Dickinson6b265f12009-03-18 16:07:26 +000092- Issue #4474: PyUnicode_FromWideChar now converts characters outside
93 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
94 and sizeof(Py_UNICODE) == 2.
95
Eric Smith6f42edb2009-03-14 11:57:26 +000096- Issue #5237: Allow auto-numbered fields in str.format(). For
97 example: '{} {}'.format(1, 2) == '1 2'.
98
Brett Cannon6c4cff02009-03-11 04:51:06 +000099- Issue #3652: Make the 'line' argument for warnings.showwarning() a
100 requirement. Means the DeprecationWarning from Python 2.6 can go away.
101
Eric Smithe9fb6862009-02-20 14:02:36 +0000102- Issue #5247: Improve error message when unknown format codes are
103 used when using str.format() with str, unicode, long, int, and
104 float arguments.
105
Raymond Hettinger08259e82009-02-18 23:10:19 +0000106- Running Python with the -3 option now also warns about classic division
107 for ints and longs.
108
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000109- Issue #5260: Long integers now consume less memory: average
110 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
111 on a 64-bit system.
112
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000113- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
114 rotating the object pointer by 4 bits to the right.
115
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000116- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
117 it now forces its argument to double before testing for infinity.
118
Benjamin Petersone18ef192009-01-20 14:21:16 +0000119- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
120
Georg Brandl29c6a282009-04-05 20:23:13 +0000121- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000122 were suppressing all exceptions. These include list(), filter(), map(),
123 zip(), and bytearray().
124
Benjamin Peterson596d3062009-01-19 15:42:23 +0000125- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
126 functions.
127
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000128- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an
129 OSError.
130
Amaury Forgeot d'Arca18392a2009-01-13 23:19:08 +0000131- Issue #4807: Port the _winreg module to Windows CE.
132
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000133- Issue #4935: The overflow checking code in the expandtabs() method common
134 to str, bytes and bytearray could be optimized away by the compiler, letting
135 the interpreter segfault instead of raising an error.
136
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000137- Issue #3720: Fix a crash when an iterator modifies its class and removes its
138 __next__ method.
139
Martin v. Löwise3422fa2009-01-12 08:11:24 +0000140- Issue #4893: Use NT threading on CE.

143
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000144- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
145 collecting the oldest generation) so that allocating lots of objects without
146 destroying them does not show quadratic performance. Based on a proposal by
147 Martin von Löwis at
148 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
149
Martin v. Löwisb90304a2009-01-07 18:40:40 +0000150- Issue #4850: Change COUNT_ALLOCS variables to Py_ssize_t.
151
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000152- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
153 an existing .py counterpart, override the co_filename attributes of all
154 code objects if the original filename is obsolete (which can happen if the
155 file has been renamed, moved, or if it is accessed through different paths).
156 Patch by Ziga Seilnacht and Jean-Paul Calderone.
157
Martin v. Löwis5344c992009-01-02 20:32:55 +0000158- Issue #4075: Use OutputDebugStringW in Py_FatalError.
159
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000160- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
161 file with `str' filename on Windows.
162
Antoine Pitrouaa687902009-01-01 14:11:22 +0000163- Issue #3680: Reference cycles created through a dict, set or deque iterator
164 did not get collected.
165
Nick Coghlan180e4002008-12-30 01:18:48 +0000166- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
167 where the tp_hash and tp_dict slots are both NULL.
168
Benjamin Peterson7af65562008-12-29 17:56:58 +0000169- Issue #4764: With io.open, IOError.filename is set when trying to open a
170 directory on POSIX systems.
171
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000172- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
173 systems.
174

176 bytearray.translate(). It was always allowed for bytes.translate().
177
Skip Montanarof205c132008-12-23 03:30:15 +0000178- Added test case to ensure attempts to read from a file opened for writing
179 fail.
180
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000181- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
182 print elapsed times, not only when some objects are uncollectable /
183 unreachable. Original patch by Neil Schemenauer.
184
Mark Dickinson1a707982008-12-17 16:14:37 +0000185- Issue #3439: Add a bit_length method to int and long.
186

191 context manager returns a value that cannot be converted to a bool.
192
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000193- Issue #4597: Fixed several opcodes that weren't always propagating
194 exceptions.
195
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000196- Issue #4445: Replace "sizeof(PyStringObject)" with
197 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
198 str instances. On a typical machine this saves 3 bytes of memory
199 (on average) per string allocation.
200
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000201- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
202 interpreter to abort ("Fatal Python error: Could not reset the stack!")
203 instead of throwing a MemoryError.
204
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000205- Issue #3689: The list reversed iterator now supports __length_hint__

210
Vinay Sajip213faca2008-12-03 23:22:58 +0000211- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000212 method on file objects with closefd=False. The file descriptor is still
213 kept open but the file object behaves like a closed file. The ``FileIO``
214 object also got a new readonly attribute ``closefd``.
215
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000216- Issue #4348: Some bytearray methods returned that didn't cause any change to
217 the bytearray, returned the same bytearray instead of a copy.
218
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000219- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.

224
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000225- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
226 exec statement.
227
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000228- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
229 method does not return iterators for the 4th and 5th items.
230
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000231- Issue #4209: Enabling unicode_literals and the print_function in the same
232 __future__ import didn't work.
233
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000234- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000235 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000236
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000237- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
238 returned a path longer than MAX_PATH. (But It's doubtful this code path is
239 really executed because I cannot move to such directory on win2k)
240
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000241- Issue #4069: When set.remove(element) is used with a set element, the element
242 is temporarily replaced with an equivalent frozenset. But the eventual
243 KeyError would always report the empty frozenset([]) as the missing key. Now
244 it correctly refers to the initial element.
245
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000246- Issue #4509: Various issues surrounding resize of bytearray objects to
247 which there are buffer exports.
248

256 short file names.
257
Matthias Klose91a3b9e2009-04-05 21:19:13 +0000258- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
259 to avoid compiler warnings.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000261- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
262 returned them on 64bit platforms.
263
Walter Dörwalded960ac2009-05-03 22:36:33 +0000264- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
265 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
266 step. This avoids problems with counting UTF-8 bytes that ignores the effect
267 of using the replace error handler in PyUnicode_DecodeUTF8().

1054
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001055- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1056 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1057 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1058 ``printf`` function, whereas PyString_FromFormat has an independent
1059 implementation and uses "%zd" on all platforms for size_t values.
1060 This makes a difference on win64, where ``printf`` needs "%Id" to display
1061 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00001081 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1082 mechanism. In the process, fix a bug where isinstance() and issubclass(),

1084 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1085 type object.

1182
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001183- Issue #2975: When compiling several extension modules with Visual Studio 2008
1184 from the same python interpreter, some environment variables would grow
1185 without limit.
1186
Benjamin Peterson37346b22008-08-23 20:27:43 +00001187- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001224What's New in Python 2.6 beta 3?
1225================================
1226
Barry Warsaw07a4a382008-08-21 01:15:08 +00001227*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001228
1229Core and Builtins
1230-----------------
1231
Guido van Rossumf8402962008-08-20 15:01:50 +00001232- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1233 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1234 extensions do not automatically benefit from the class attribute
1235 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1236 to their tp_flags field if they care. This is a backwards
1237 compatibility feature; in 3.0, all types will use the cache by
1238 default.
1239
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001240- Keyword arguments can now follow starred arguments. (``f(a, *args,
1241 keyword=23)`` is now valid syntax.)
1242
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001243- ctypes function pointers that are COM methods have a boolean True
1244 value again.
1245
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001246- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1247 by denying s# to parse objects that have a releasebuffer procedure,
1248 and introducing s*.
1249
Georg Brandl1e13ea92008-08-11 09:07:59 +00001250- Issue #3537: Fix an assertion failure when an empty but presized dict
1251 object was stored in the freelist.
1252
Mark Dickinsonb6467572008-08-04 21:30:09 +00001253- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1254 ValueError consistently across platforms.
1255
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001256- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1257 (64bit Unix, for example), unichr() would truncate its argument and return
1258 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1259
Neal Norwitze7d8be82008-07-31 17:17:14 +00001260- Apply security patches from Apple.
1261
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001262- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1263 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1264
Antoine Pitrou92f82162008-07-25 22:22:08 +00001265- Issue #1819: function calls with several named parameters are now on
1266 average 35% faster (as measured by pybench).
1267
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001268- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1269 the python debugger steps into a class statement: the free variables (local
1270 variables defined in an outer scope) would be deleted from the outer scope.
1271
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001272- Issue #2620: Overflow checking when allocating or reallocating memory
1273 was not always being done properly in some python types and extension
1274 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1275 all been updated to perform better checks and places in the code that
1276 would previously leak memory on the error path when such an allocation
1277 failed have been fixed.
1278
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001279Library
1280-------
1281
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001282- Issue #3612: Added some missing basic types in ctypes.wintypes.
1283
Benjamin Petersone977ad42008-08-20 01:42:01 +00001284- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1285 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1286
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001287- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1288 version reported by these tools does not necessarily follow the python
1289 version numbering scheme, so the module is less strict when parsing it.
1290
Nick Coghlanf70385a2008-08-18 12:42:46 +00001291- Issue #2235: Added Py3k warnings for types which will become unhashable
1292 under the stricter __hash__ inheritance rules in 3.0. Several types
1293 which did not meet the rules for hash invariants and were already
1294 unhashable in 3.0 have now been explicitly flagged as unhashable in
1295 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1296 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1297
Brett Cannon88f801d2008-08-18 00:46:22 +00001298- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1299 imported into the module but exposed as part of the module's API.
1300
Brett Cannon7b96f072008-08-18 00:41:11 +00001301- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1302
Brett Cannon46225e72008-08-18 00:36:52 +00001303- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001305- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1306
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001307- Issue #3575: Incremental decoder's decode function now takes bytearray
1308 by using 's*' instead of 't#'.
1309
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001310- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001311 fails unicode conversion on 2nd parameter. (windows only)
1312
Facundo Batista94f243a2008-08-17 03:38:39 +00001313- Issue 2464. urllib2 now supports a malformation in the URL received
1314 in a redirect.
1315
Brett Cannonabe423e2008-08-16 21:47:07 +00001316- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001317 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001318
Facundo Batistaeb90b782008-08-16 14:44:07 +00001319- Issue #2776: fixed small issue when handling an URL with double slash
1320 after a 302 response in the case of not going through a proxy.
1321
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001322- Issue #2676: in the email package, content-type parsing was hanging on
1323 pathological input because of quadratic or exponential behaviour of a
1324 regular expression.
1325
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001326- Issue #3476: binary buffered reading through the new "io" library is now
1327 thread-safe.
1328
Brett Cannonbf3157b2008-08-14 05:00:03 +00001329- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1330 since mimetools itself is deprecated. Because modules are cached, all
1331 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1332
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001333- Issue #3134: shutil referenced undefined WindowsError symbol.
1334
Robert Schuppenies14646332008-08-10 11:01:53 +00001335- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1336 menu entries were not deleted.
1337
Brett Cannon83e81842008-08-09 23:30:55 +00001338- Copied the implementation of reduce() to _functools.reduce() to have a
1339 version that did not raise a DeprecationWarning under -3.
1340
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001341- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1342 a MemoryError rather than silently stop the iteration.
1343
Guido van Rossum59ce9012008-08-09 14:55:34 +00001344- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1345 to _sre.compile() will now be rejected. This should not affect anybody
1346 since the re.compile() function never generates invalid re-bytecode.
1347
Skip Montanaroa032bf42008-08-08 22:52:51 +00001348- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1349 upon first access it can be automatically initialized from the csv file if
1350 it wasn't initialized during instantiation.
1351
Brett Cannon3aa2a492008-08-06 22:28:09 +00001352- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1353 the reload() built-in has been removed.
1354
Brett Cannon7e30b672008-08-04 21:52:25 +00001355- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001356 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1359 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
1360 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1361 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.

1364 raised an AttributeError.
1365
Benjamin Peterson01a24322008-07-28 23:35:27 +00001366- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001367 asking for a specific length. This problem only affected files opened
1368 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001369
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001370- Issue #3449: Update decimal module to use most recent specification
1371 (v. 1.68) and tests (v. 2.58) from IBM.

1383 invalid arguments.
1384

1392
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001393- Issue #3394: zipfile.writestr sets external attributes when passed a
1394 file name rather than a ZipInfo instance, so files are extracted with
1395 mode 0600 rather than 000 under Unix.
1396
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001397- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1398 argument in python 2.5, this broke code that subclassed Popen to include its
1399 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001409- Issue #2235: the C API function PyObject_HashNotImplemented and its
1410 interaction with the tp_hash slot (added in 2.6b2) are now documented
1411
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001412- Issue #643841: The language reference now provides more detailed
1413 coverage of the lookup process for special methods. The disclaimers
1414 regarding lack of coverage of new-style classes have also been
1415 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001418What's New in Python 2.6 beta 2?
1419================================
1420
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001421*Release date: 17-Jul-2008*
1422
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001423Core and Builtins
1424-----------------
1425
Georg Brandl3e483f62008-07-16 22:57:41 +00001426- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1427 its methods now allow for items objects that can be converted to
1428 an integer using operator.index().
1429
Mark Dickinson64b7e502008-07-16 09:40:03 +00001430- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1431 produced a ValueError instead of giving the correct float.
1432
Eric Smitha5fa5a22008-07-16 00:11:49 +00001433- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1434 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1435
Mark Dickinson7103aa42008-07-15 19:08:33 +00001436- Issue #3008: the float type has a new instance method 'float.hex'
1437 and a new class method 'float.fromhex' to convert floating-point
1438 numbers to and from hexadecimal strings, respectively.
1439
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001440- Issue #2235: __hash__ is once again inherited by default. To allow
1441 collections.Hashable to remain meaningful in the presence of the
1442 default hash implementation (object.__hash__), it is now possible
1443 to explicit block inheritance of hash by setting __hash__=None at
1444 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1445 level.
1446
Nick Coghlanb028f502008-07-13 14:52:36 +00001447- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1448 the parent module cannot be found while performing an absolute import.
1449 This means that an incorrectly defined __package__ attribute will
1450 now only prevent relative imports in that module rather than causing
1451 all imports from that module to fail.
1452
Nick Coghlan14ff9942008-07-08 14:21:42 +00001453- Issue #2517: Allow unicode messages in Exceptions again by correctly
1454 bypassing the instance dictionary when looking up __unicode__ on
1455 new-style classes.
1456
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001457- Issue #3242: Fix a crash inside the print statement, if sys.stdout is

Georg Brandl5cc774e2008-06-11 20:28:06 +00001924 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001925

Georg Brandl3ee81df2008-05-17 18:14:43 +00001986- Issue #1631171: Re-implement the 'warnings' module in C (the
1987 original Python code has been kept as backup). This will allow for
1988 using the 'warning's machinery in such places as the parser where
1989 use of pure Python code is not possible. Both the ``showarning()``
1990 and ``formatwarning()`` gain an optional 'line' argument which is
1991 not called by default for backwards-compatibility reasons. Setting
1992 ``warnings.showwarning()`` to an implementation that lacks support
1993 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002056- Issue #2550: The approach used by client/server code for obtaining
2057 ports to listen on in network-oriented tests has been refined in an
2058 effort to facilitate running multiple instances of the entire
2059 regression test suite in parallel without issue.
2060 test_support.bind_port() has been fixed such that it will always
2061 return a unique port -- which wasn't always the case with the
2062 previous implementation, especially if socket options had been set
2063 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2064 new implementation of bind_port() will actually raise an exception
2065 if it is passed an AF_INET/SOCK_STREAM socket with either the
2066 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2067 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2068 the socket it's been passed. This currently only applies to
2069 Windows. This option prevents any other sockets from binding to the
2070 host/port we've bound to, thus removing the possibility of the
2071 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2072 when a second SOCK_STREAM socket binds and accepts to a host/port
2073 that's already been bound by another socket. The optional preferred
2074 port parameter to bind_port() has been removed. Under no
2075 circumstances should tests be hard coding ports!
2076
2077 test_support.find_unused_port() has also been introduced, which will
2078 pass a temporary socket object to bind_port() in order to obtain an
2079 unused port. The temporary socket object is then closed and
2080 deleted, and the port is returned. This method should only be used
2081 for obtaining an unused port in order to pass to an external program
2082 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2083 a parameter to a server-oriented class that doesn't give you direct
2084 access to the underlying socket used.
2085
2086 Finally, test_support.HOST has been introduced, which should be used
2087 for the host argument of any relevant socket calls (i.e. bind and
2088 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002089
2090 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002091 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002092 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2093 test_asynchat and test_socket_ssl.
2094
Georg Brandl3ee81df2008-05-17 18:14:43 +00002095 It is now possible for multiple instances of the regression test
2096 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002280 optional: it defaults to the traceback of the exception that is
2281 currently being handled (is mandatory to be in the middle of an
2282 exception, otherwise it raises ValueError).

2298 from 't' to '?'.
2299
Thomas Heller78b8f442008-03-05 14:53:39 +00002300- The bundled libffi copy is now in sync with the recently released
2301 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002302 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
2303 files are used. On all linux systems the --with-system-ffi
2304 configure option defaults to "yes".

2363-----------------
2364
Fred Drakea8ee94b2008-03-01 02:45:07 +00002365- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002366 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002367
Georg Brandlad61bc82008-02-23 15:11:18 +00002368- Issue #2067: file.__exit__() now calls subclasses' close() method.
2369
2370- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002371
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002372- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002373 issue 215555 for a discussion.
2374
Eric Smitha73fbe72008-02-23 03:09:44 +00002375- Added the future_builtins module, which contains hex() and oct().
2376 These are the PEP 3127 version of these functions, designed to be
2377 compatible with the hex() and oct() builtins from Python 3.0. They
2378 differ slightly in their output formats from the existing, unchanged
2379 Python 2.6 builtins. The expected usage of the future_builtins
2380 module is:
2381 from future_builtins import hex, oct
2382
Eric Smith7ef40bf2008-02-20 23:34:22 +00002383- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2384 exponents for exponents with absolute value < 100. Follows C99
2385 standard. This is a change on Windows, which would use 3 digits.
2386 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2387 so that any alterations it does to the resulting string will be
2388 available in stringlib/formatter.h (for float.__format__).
2389
Eric Smith5a3c1352008-02-19 13:21:56 +00002390- Implemented PEP 3101, Advanced String Formatting. This adds a new
2391 builtin format(); a format() method for str and unicode; a
2392 __format__() method to object, str, unicode, int, long, float, and
2393 datetime; the class string.Formatter; and the C API
2394 PyObject_Format().
2395
Georg Brandl3ee81df2008-05-17 18:14:43 +00002396- Fixed several potential crashes, all caused by specially crafted
2397 __del__ methods exploiting objects in temporarily inconsistent
2398 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002399
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002400- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002401 prevent a possible crash: an Abstract Base Class would try to access
2402 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002403
Georg Brandl3ee81df2008-05-17 18:14:43 +00002404- Fixed repr() and str() of complex numbers with infinity or nan as
2405 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002406
Georg Brandl3ee81df2008-05-17 18:14:43 +00002407- Clear all free lists during a gc.collect() of the highest generation
2408 in order to allow pymalloc to free more arenas. Python may give back
2409 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002410
Georg Brandl3ee81df2008-05-17 18:14:43 +00002411- Issue #2045: Fix an infinite recursion triggered when printing a
2412 subclass of collections.defaultdict, if its default_factory is set
2413 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002414
Christian Heimesf75dbef2008-02-08 00:11:31 +00002415- Fixed a minor memory leak in dictobject.c. The content of the free
2416 list was not freed on interpreter shutdown.
2417
Georg Brandl3ee81df2008-05-17 18:14:43 +00002418- Limit free list of method and builtin function objects to 256
2419 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002420
Georg Brandl3ee81df2008-05-17 18:14:43 +00002421- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2422 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002423 to compact the internal free lists of pre-allocted ints and floats.
2424
Georg Brandl3ee81df2008-05-17 18:14:43 +00002425- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2426 calls. Python expected the return type int but the fork familie
2427 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002428
Georg Brandl3ee81df2008-05-17 18:14:43 +00002429- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2430 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002431
Georg Brandl3ee81df2008-05-17 18:14:43 +00002432- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2433 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002434
Georg Brandl3ee81df2008-05-17 18:14:43 +00002435- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2436 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002437
Georg Brandl3ee81df2008-05-17 18:14:43 +00002438- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2439 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002440
Georg Brandl3ee81df2008-05-17 18:14:43 +00002441- Patch #1473257: generator objects gain a gi_code attribute. This is
2442 the same object as the func_code attribute of the function that
2443 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002444
Georg Brandl3ee81df2008-05-17 18:14:43 +00002445- Issue #1920: "while 0" statements were completely removed by the
2446 compiler, even in the presence of an "else" clause, which is
2447 supposed to be run when the condition is false. Now the compiler
2448 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002449
Guido van Rossumeead05f2008-01-24 18:21:02 +00002450- A few crashers fixed: weakref_in_del.py (issue #1377858);
2451 loosing_dict_ref.py (issue #1303614, test67.py);
2452 borrowed_ref_[34].py (not in tracker).
2453
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002454- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002455 suppressed while an extension is loaded by calling SetErrorMode in
2456 dynload_win.c. The error is still reported properly.
2457
Georg Brandl3ee81df2008-05-17 18:14:43 +00002458- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002459 several extension methods and modules do not work without unicode
2460 support.
2461
Georg Brandl26543b12008-01-21 18:36:51 +00002462- Issue #1882: when compiling code from a string, encoding cookies in the
2463 second line of code were not always recognized correctly.
2464
Georg Brandl14404b62008-01-19 19:27:05 +00002465- Issue #1679: "0x" was taken as a valid integer literal.
2466
Georg Brandl6caad7d2008-01-26 14:19:22 +00002467- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002468 added.
2469
Christian Heimesc94e2b52008-01-14 04:13:37 +00002470- sys.float_info / PyFloat_GetInfo: The floating point information
2471 object was converted from a dict to a specialized structseq object.
2472
Georg Brandl3ee81df2008-05-17 18:14:43 +00002473- Patch #1816: Added sys.flags structseq. It exposes the status of
2474 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002475
Georg Brandl3ee81df2008-05-17 18:14:43 +00002476- Objects/structseq.c: Implemented new structseq representation. The
2477 patch makes structseqs (e.g. the return value of os.stat) more
2478 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002479
Georg Brandl3ee81df2008-05-17 18:14:43 +00002480- Patch #1700288: added a type attribute cache that caches method
2481 accesses, resulting in speedups in heavily object-oriented code.

2489 envvar and sys.dont_write_bytecode attribute. All these can be set
2490 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002491
Georg Brandl3ee81df2008-05-17 18:14:43 +00002492- Improve some exception messages when Windows fails to load an
2493 extension module. Now we get for example '%1 is not a valid Win32
2494 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002495

2499 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002500
Christian Heimes0a8143f2007-12-18 23:22:54 +00002501- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002502 and INF. float("nan"), float("inf") and float("-inf") now work on
2503 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002504
Georg Brandl3ee81df2008-05-17 18:14:43 +00002505- Compiler now generates simpler and faster code for dictionary
2506 literals. The oparg for BUILD_MAP now indicates an estimated
2507 dictionary size. There is a new opcode, STORE_MAP, for adding
2508 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002537- Patch #1739468: Directories and zipfiles containing a __main__.py
2538 file can now be directly executed by passing their name to the
2539 interpreter. The directory/zipfile is automatically inserted as the
2540 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002542- Issue #1265: Fix a problem with sys.settrace, if the tracing
2543 function uses a generator expression when at the same time the
2544 executed code is closing a paused generator.

2551
Georg Brandl3ee81df2008-05-17 18:14:43 +00002552- The enumerate() builtin function is no longer bounded to sequences
2553 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2554 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002555
Georg Brandl3ee81df2008-05-17 18:14:43 +00002556- Issue #1686386: Tuple's tp_repr did not take into account the
2557 possibility of having a self-referential tuple, which is possible
2558 from C code. Nor did object's tp_str consider that a type's tp_str
2559 could do something that could lead to an inifinite recursion.
2560 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2561 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002562
Georg Brandl3ee81df2008-05-17 18:14:43 +00002563- Issue #1164: It was possible to trigger deadlock when using the
2564 'print' statement to write to a file since the GIL was not released
2565 as needed. Now PyObject_Print() does the right thing along with
2566 various tp_print implementations of the built-in types and those in
2567 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002569- Issue #1147: Exceptions were directly allowing string exceptions in
2570 their throw() method even though string exceptions no longer
2571 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00002575
Brett Cannon1e534b52007-09-07 04:18:30 +00002576- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002577 PyObject_Call() never calling back out to Python code to trigger
2578 recursion depth updates/checks. Required the creation of a static
2579 RuntimeError instance in case normalizing an exception put the
2580 recursion check value past its limit. Fixes crashers
2581 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00002596- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002597 __*__ attributes. (Some already existed, e.g., __doc__ and
2598 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002599
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002600- Add -3 option to the interpreter to warn about features that are
2601 deprecated and will be changed/removed in Python 3.0.
2602
Georg Brandl2134e752007-05-21 20:34:16 +00002603- Patch #1686487: you can now pass any mapping after '**' in function
2604 calls.
2605
Collin Winter62903052007-05-18 23:11:24 +00002606- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002607 "except E as target:". This is to provide forwards compatibility
2608 with Python 3.0.

2614
Vinay Sajip8549ce32007-05-06 17:53:37 +00002615- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002616 setting a plain string, ie don't expand to single letter identifiers.
2617
Raymond Hettinger13936692007-04-11 18:40:58 +00002618- Request #1191699: Slices can now be pickled.
2619
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002620- Request #1193128: str.translate() now allows a None argument for
2621 translations that only remove characters without re-mapping the
2622 remaining characters.
2623
Georg Brandl5cb76c12007-03-21 09:00:39 +00002624- Patch #1682205: a TypeError while unpacking an iterable is no longer

2626
Neal Norwitzaa754b72007-03-21 06:39:48 +00002627- Remove unused file Python/fmod.c.
2628
Guido van Rossum143b5642007-03-23 04:58:42 +00002629- Bug #1683368: The object.__init__() and object.__new__() methods are
2630 now stricter in rejecting excess arguments. The only time when
2631 either allows excess arguments is when it is not overridden and the
2632 other one is. For backwards compatibility, when both are
2633 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002634 warning later). Also, type.__init__() insists on the same signature
2635 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002636
Georg Brandl3ee81df2008-05-17 18:14:43 +00002637- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2638 object to complex using its __complex__() method before falling back
2639 to the __float__() method. Therefore, the functions in the cmath
2640 module now can operate on objects that define a __complex__()
2641 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002642
Georg Brandl3ee81df2008-05-17 18:14:43 +00002643- Patch #1623563: allow __class__ assignment for classes with
2644 __slots__. The old and the new class are still required to have the
2645 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002646

2651 ``object.__reduce_ex__()`` is called with an object that is faking
2652 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002653
Georg Brandl3ee81df2008-05-17 18:14:43 +00002654- Patch #1680015: Don't modify __slots__ tuple if it contains an

2658
Georg Brandl7b9c5552007-03-12 14:30:05 +00002659- Bug #1678647: write a newline after printing an exception in any
2660 case, even when converting the value to a string failed.
2661
Georg Brandl871f1bc2007-03-12 13:17:36 +00002662- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002663 its argument, if it exists. If not, it will work like before. This
2664 allows customizing the output of dir() in the presence of a
2665 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002666
Collin Winter276887b2007-03-12 16:11:39 +00002667- Patch #922167: Python no longer segfaults when faced with infinitely
2668 self-recursive reload() calls (as reported by bug #742342).
2669
Georg Brandl3ee81df2008-05-17 18:14:43 +00002670- Patch #1675981: remove unreachable code from ``type.__new__()``
2671 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002673- Patch #1491866: change the complex() constructor to allow
2674 parthensized forms. This means complex(repr(x)) now works instead of
2675 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002676
Georg Brandlaa2321b2007-03-07 00:40:28 +00002677- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002678 makes the filenames the warning module prints much more sensible
2679 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002680

2682 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002683 variable is given, but break into the interactive interpreter just
2684 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00002691
Georg Brandl0fca97a2007-03-05 22:28:08 +00002692- Patch #1674228: when assigning a slice (old-style), check for the
2693 sq_ass_slice instead of the sq_slice slot.
2694
Georg Brandl3ee81df2008-05-17 18:14:43 +00002695- When printing an unraisable error, don't print exceptions. before
2696 the name. This duplicates the behavior whening normally printing
2697 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00002698
Georg Brandl3ee81df2008-05-17 18:14:43 +00002699- Bug #1653736: Properly discard third argument to

2754
Armin Rigo7ccbca92006-10-04 12:17:45 +00002755- A number of places, including integer negation and absolute value,

Georg Brandl3ee81df2008-05-17 18:14:43 +00003265 are set for invalid interpolation sequences that would lead to

3322 TestCase and TestSuite subclasses (not instances) are no longer
3323 accepted in TestSuite.addTest(). This should cause no
3324 incompatibility since it never made sense with ordinary subclasses
3325 -- the failure just occurred later, with a more cumbersome
3326 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003607- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3608 with RFC 3207 and forgets any knowledge obtained from the server not
3609 obtained from the TLS negotiation itself. Patch contributed by Bill
3610 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003611
Georg Brandl3ee81df2008-05-17 18:14:43 +00003612- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003613 that the SMTP.starttls() caller no longer needs to call ehlo()
3614 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003615 does not claim to support starttls. Adds the
3616 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3697 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3698 silently miscode subclasses of those types. Now, it raises a
3699 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003700

Georg Brandl3ee81df2008-05-17 18:14:43 +00003715 time so that opening a database previously created with the DB_DUP
3716 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3717 opens. Specifically: dictionary assignment to a DB object will
3718 replace all values for a given key when the database allows
3719 duplicate values. DB users should use DB.put(k, v) when they want
3720 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003721

3727 characters with ASCII value less than 32. Also, it correctly quotes
3728 dots only if they occur on a single line, as opposed to the previous
3729 behavior of quoting dots if they are the second character of any
3730 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003731

Georg Brandl3ee81df2008-05-17 18:14:43 +00004000 periodic threadstate and signal checking in tight loops. By
4001 default, this option is turned-off. It should only be enabled in
4002 debugged, performance critical applications.

4054
Georg Brandl3ee81df2008-05-17 18:14:43 +00004055- Unified naming convention for free lists and their limits. All free
4056 lists in Object/ are named ``free_list``, the counter ``numfree``

4058 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004059
Georg Brandl3ee81df2008-05-17 18:14:43 +00004060- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4061 to ``PyTuple_SetItem``, it can be used to populate a brand new

4074
Georg Brandl3ee81df2008-05-17 18:14:43 +00004075- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4076 of w# format code incorrectly truncated the length to an int, even
4077 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4078 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004079
Georg Brandl3ee81df2008-05-17 18:14:43 +00004080- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4102 outside of pystate.c and should not be necessary.
4103
Georg Brandl3ee81df2008-05-17 18:14:43 +00004104- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4105 absolute imports. In earlier versions they might have used relative
4106 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004107
Georg Brandl3ee81df2008-05-17 18:14:43 +00004108- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4109 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004110
Georg Brandl3ee81df2008-05-17 18:14:43 +00004111- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004136- Removed the macfs module. It had been deprecated since Python 2.5.
4137 This lead to the deprecation of macostools.touched() as it relied
4138 solely on macfs and was a no-op under OS X.
