Anthony Baxter51bcb682006-04-05 14:51:42 +00008=================================

Nick Coghlanc649ec52006-05-29 12:43:05 +000010*Release date: XX-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +000011
12Core and builtins
13-----------------
14
Brett Cannonea3912b2006-06-13 21:46:41 +000015- Bug #992017: A classic class that defined a __coerce__() method that returned
16 its arguments swapped would infinitely recurse and segfault the interpreter.
17
Neal Norwitz909eb122006-06-12 02:13:21 +000018- Fix the socket tests so they can be run concurrently.
19
Neal Norwitzb9845e72006-06-12 02:11:18 +000020- Removed 5 integers from C frame objects (PyFrameObject).
21 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
22
Brett Cannon22565aa2006-06-09 22:31:23 +000023- Bug #532646: object.__call__() will continue looking for the __call__
24 attribute on objects until one without one is found. This leads to recursion
25 when you take a class and set its __call__ attribute to an instance of the
26 class. Originally fixed for classic classes, but this fix is for new-style.
27 Removes the infinite_rec_3 crasher.
28
Georg Brandl24250812006-06-09 18:45:48 +000029- The string and unicode methods startswith() and endswith() now accept
30 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
31
Brett Cannonde3b0522006-06-08 17:00:45 +000032- Buffer objects, at the C level, never used the char buffer
33 implementation even when the char buffer for the wrapped object was
34 explicitly requested (originally returned the read or write buffer).
35 Now a TypeError is raised if the char buffer is not present but is
36 requested.
37
Georg Brandlddbaa662006-06-04 21:56:52 +000038- Patch #1346214: Statements like "if 0: suite" are now again optimized
39 away like they were in Python 2.4.
40
Georg Brandlb7c8f542006-05-27 12:30:25 +000041- Builtin exceptions are now full-blown new-style classes instead of
42 instances pretending to be classes, which speeds up exception handling
43 by about 80% in comparison to 2.5a2.
44
Martin v. Löwisd004fc82006-05-27 08:36:52 +000045- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
46 Unicode 4.1.
47
Georg Brandlf4ef1162006-05-26 18:03:31 +000048- Patch #921466: sys.path_importer_cache is now used to cache valid and
49 invalid file paths for the built-in import machinery which leads to
50 fewer open calls on startup.
51
Tim Peters696cf432006-05-24 21:10:40 +000052- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
53 of-2 bases. The largest speedup is for inputs with about 1000 decimal
54 digits. Conversion from non-power-of-2 bases remains quadratic-time in
55 the number of input digits (it was and remains linear-time for bases
56 2, 4, 8, 16 and 32).
57
Tim Petersb713ec22006-05-23 18:45:30 +000058- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
59 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
60 an integer close to ``sys.maxint``. This was repaired by patch
61 #1335972, which also gives a nice speedup.
62
Richard Jonescebbefc2006-05-23 18:28:17 +000063- Patch #1337051: reduced size of frame objects.
64
65- PyErr_NewException now accepts a tuple of base classes as its
66 "base" parameter.
67
Richard Jones7c88dcc2006-05-23 10:37:38 +000068- Patch #876206: function call speedup by retaining allocated frame
69 objects.
70
Georg Brandl7b90e162006-05-18 07:01:27 +000071- Bug #1462152: file() now checks more thoroughly for invalid mode
72 strings and removes a possible "U" before passing the mode to the
73 C library function.
74
Neal Norwitz1004a532006-05-15 07:17:23 +000075- Patch #1488312, Fix memory alignment problem on SPARC in unicode
76
Neal Norwitz373f0a72006-05-15 07:04:36 +000077- Bug #1487966: Fix SystemError with conditional expression in assignment
78
Martin v. Löwis879768d2006-05-11 13:28:43 +000079- WindowsError now has two error code attributes: errno, which carries
80 the error values from errno.h, and winerror, which carries the error
81 values from winerror.h. Previous versions put the winerror.h values
82 (from GetLastError()) into the errno attribute.
83
Martin v. Löwis77736712006-05-04 05:51:03 +000084- Patch #1475845: Raise IndentationError for unexpected indent.
85
Neal Norwitzc4edb0e2006-05-02 04:43:14 +000086- Patch #1479181: split open() and file() from being aliases for each other.
87
Tim Peters44bd9862006-06-01 13:49:23 +000088- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
89 methods were always silently ignored by dictionaries when comparing keys.
90 They are now passed through (except when using the C API function
91 ``PyDict_GetItem()``, whose semantics did not change).
92
93- Bug #1456209: In some obscure cases it was possible for a class with a
94 custom ``__eq__()`` method to confuse dict internals when class instances
95 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
96 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +000098Extension Modules
99-----------------
100
Brett Cannon6ee7d012006-06-08 16:23:04 +0000101- Change binascii.hexlify to accept a read-only buffer instead of only a char
102 buffer and actually follow its documentation.
103
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000104- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
105
Nick Coghlanc649ec52006-05-29 12:43:05 +0000106- Patch #1478788 (modified version): The functional extension module has
107 been renamed to _functools and a functools Python wrapper module added.
108 This provides a home for additional function related utilities that are
109 not specifically about functional programming. See PEP 309.
110
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000111- Patch #1493701: performance enhancements for struct module.
112
Georg Brandl378d5922006-05-17 14:26:50 +0000113- Patch #1490224: time.altzone is now set correctly on Cygwin.
114
Georg Brandl8d3342b2006-05-16 07:38:27 +0000115- Patch #1435422: zlib's compress and decompress objects now have a
116 copy() method.
117
Andrew MacIntyre92913322006-06-13 15:04:24 +0000118- Patch #1454481: thread stack size is now tunable at runtime for thread
119 enabled builds on Windows and systems with Posix threads support.
120
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000121- On Win32, os.listdir now supports arbitrarily-long Unicode path names
122 (up to the system limit of 32K characters).
123
124- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
125 As a result, these functions now raise WindowsError instead of OSError.
126
Tim Peters7a822da2006-05-25 21:50:17 +0000127- ``time.clock()`` on Win64 should use the high-performance Windows
128 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
129 Windows platforms).
130
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000131- Calling Tk_Init twice is refused if the first call failed as that
132 may deadlock.
133
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000134- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
135 accept it without potentially using an uninitialized pointer.
136
137- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
138 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
139 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000140
Gregory P. Smith372b5832006-06-05 18:48:21 +0000141- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000142 [pybsddb project SF patch number 1466734]
143
Gregory P. Smith372b5832006-06-05 18:48:21 +0000144- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
145 parameter is supplied. [SF pybsddb bug #1477863]
146
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000147- bsddb: the __len__ method of a DB object has been fixed to return correct
148 results. It could previously incorrectly return 0 in some cases.
149 Fixes SF bug 1493322 (pybsddb bug 1184012).
150
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000151- bsddb: the bsddb.dbtables Modify method now raises the proper error and
152 aborts the db transaction safely when a modifier callback fails.
153 Fixes SF python patch/bug #1408584.
154
Gregory P. Smith372b5832006-06-05 18:48:21 +0000155
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000156Library
157-------
158
Georg Brandl83cc0d02006-06-14 08:50:03 +0000159- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
160 mime.types file for determining MIME types.
161
Georg Brandl2605ca82006-06-14 06:08:31 +0000162- Bug #1339007: Shelf objects now don't raise an exception in their
163 __del__ method when initialization failed.
164
Martin v. Löwisd8251432006-06-14 05:21:04 +0000165- Patch #1455898: The MBCS codec now supports the incremental mode for
166 double-byte encodings.
167
Tim Peters43898b42006-06-14 04:09:25 +0000168- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
169 guarantee that adjacent triples in the return list always describe
170 non-adjacent blocks. Previously, a pair of matching blocks could end
171 up being described by multiple adjacent triples that formed a partition
172 of the matching pair.
173
Greg Ward0e0c9f42006-06-11 16:24:11 +0000174- Bug #1498146: fix optparse to handle Unicode strings in option help,
175 description, and epilog.
176
Greg Wardd1c797e2006-06-11 14:42:41 +0000177- Bug #1366250: minor optparse documentation error.
178
Greg Ward7f547402006-06-11 00:40:49 +0000179- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
180 clarify docs.
181
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000182- The wsgiref package has been added to the standard library.
183
Nick Coghlan676725d2006-06-08 13:54:49 +0000184- The functions update_wrapper() and wraps() have been added to the functools
185 module. These make it easier to copy relevant metadata from the original
186 function when writing wrapper functions.
187
Tim Petersd6a9eef2006-06-05 01:48:21 +0000188- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
189 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000190
Martin v. Löwis3f767792006-06-04 19:36:28 +0000191- Patch #1359618: Speed up charmap encoder by using a trie structure
192 for lookup.
193
Tim Petersd609b1a2006-06-02 23:22:51 +0000194- The functions in the ``pprint`` module now sort dictionaries by key
195 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
196 if and only if its display required more than one line, although that
197 wasn't documented. The new behavior increases predictability; e.g.,
198 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
199
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000200- Patch #1497027: try HTTP digest auth before basic auth in urllib2
201 (thanks for J. J. Lee).
202
Georg Brandl2b330372006-05-28 20:23:12 +0000203- Patch #1496206: improve urllib2 handling of passwords with respect to
204 default HTTP and HTTPS ports.
205
George Yoshidaf3c65de2006-05-28 16:39:09 +0000206- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
207
Bob Ippolito7298f272006-05-23 18:43:47 +0000208- Patch #1281707: speed up gzip.readline.
209
Georg Brandlb89316f2006-05-17 15:51:16 +0000210- Patch #1180296: Two new functions were added to the locale module:
211 format_string() to get the effect of "format % items" but locale-aware,
212 and currency() to format a monetary number with currency sign.
213
Georg Brandle3a25832006-05-17 14:56:04 +0000214- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
215 and several features added, such as speed and geometry control.
216
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000217- Patch #1488881: add support for external file objects in bz2 compressed
218 tarfiles.
219
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000220- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
221 stdout arguments, making it possible to redirect input and output
222 for remote debugging.
223
224- Patch #1484695: Update the tarfile module to version 0.8. This fixes
225 a couple of issues, notably handling of long file names using the
226 GNU LONGNAME extension.
227
228- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
229 new flag when ``name`` is already the name of an option flag.
230
231- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
232 package.
233
234- Patch #1472854: make the rlcompleter.Completer class usable on non-
235 UNIX platforms.
236
237- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
238
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000239- Bug #1472827: correctly escape newlines and tabs in attribute values in
240 the saxutils.XMLGenerator class.

Georg Brandl66a0dbb2006-06-08 12:54:13 +0000246- Bug #1502728: Correctly link against librt library on HP-UX.
247
Martin v. Löwis222c5152006-06-03 07:37:13 +0000248- OpenBSD 3.9 is supported now.
249
Martin v. Löwisa43190b2006-05-22 09:15:18 +0000250- Patch #1492356: Port to Windows CE.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000270What's New in Python 2.5 alpha 2?
271=================================
272
273*Release date: 27-APR-2006*
274
275Core and builtins
276-----------------
277
Thomas Heller1b046642006-04-18 18:51:06 +0000278- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
279 by converting these apis from macros into exported functions again:
280
281 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
282 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
283 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
284 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
285 PyRun_String Py_CompileString
286
Martin v. Löwis45294a92006-04-18 06:24:08 +0000287- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
288
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000289- All uses of PyStructSequence_InitType have been changed to initialize
290 the type objects only once, even if the interpreter is initialized
291 multiple times.
292
Neal Norwitz61546162006-04-14 05:20:28 +0000293- Bug #1454485, array.array('u') could crash the interpreter. This was
294 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
295 to unicode when it didn't make sense. 'u#' now requires a unicode string.
296
297- Py_UNICODE is unsigned. It was always documented as unsigned, but
298 due to a bug had a signed value in previous versions.
299
Tim Peters3a5e8b12006-04-11 01:44:07 +0000300- Patch #837242: ``id()`` of any Python object always gives a positive
301 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
302 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000303 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000304 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000305
Tim Peters3a5e8b12006-04-11 01:44:07 +0000306 def __hash__(self):
307 return id(self) # WRONG
308
309 because a hash result must be a (short) Python int but it was always
310 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000311 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000312 was always usable as a hash value before this patch. That's no longer
313 necessarily so.
314
315- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000316 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000317 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000318 #1454844)
319
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000320- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
321 involving generators that have paused outside of any ``try`` or ``with``
322 blocks. (In 2.5a1, a paused generator that was part of a reference
323 cycle could not be garbage collected, regardless of whether it was
324 paused in a ``try`` or ``with`` block.)

333 fails with an error condition.
334
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000335- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.

341 a temporary db (file=None) with the 'n' flag to truncate on open.
342
343- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
344 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000345
Armin Rigoa9017c32006-04-19 11:50:27 +0000346- Patch #1062014: AF_UNIX sockets under Linux have a special
347 abstract namespace that is now fully supported.
348
Anthony Baxter51bcb682006-04-05 14:51:42 +0000349Library
350-------
351
Tim Peters711bf302006-04-25 03:31:36 +0000352- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
353 a doctest to be skipped (the code is not run, and the expected output
354 or exception is ignored).
355
Nick Coghlanda2268f2006-04-24 04:37:15 +0000356- Fixed contextlib.nested to cope with exceptions being raised and
357 caught inside exit handlers.
358
Greg Wardab05edc2006-04-23 03:47:58 +0000359- Updated optparse module to Optik 1.5.1 (allow numeric constants in
360 hex, octal, or binary; add ``append_const`` action; keep going if
361 gettext cannot be imported; added ``OptionParser.destroy()`` method;
362 added ``epilog`` for better help generation).
363
Tim Peters21fbd572006-04-21 21:18:10 +0000364- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
365 called from a thread spawned as a side effect of importing a module.
366
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000367- The pydoc module now supports documenting packages contained in
368 .zip or .egg files.
369
370- The pkgutil module now has several new utility functions, such
371 as ``walk_packages()`` to support working with packages that are either
372 in the filesystem or zip files.
373
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000374- The mailbox module can now modify and delete messages from
375 mailboxes, in addition to simply reading them. Thanks to Gregory

Anthony Baxtere29002c2006-04-12 12:07:31 +0000388- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
389 Windows. Bug #1469163.
390
Phillip J. Eby47032112006-04-11 01:07:43 +0000391- The warnings, linecache, inspect, traceback, site, and doctest modules
392 were updated to work correctly with modules imported from zipfiles or
393 via other PEP 302 __loader__ objects.
394
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000395- Patch #1467770: Reduce usage of subprocess._active to processes which
396 the application hasn't waited on.
397
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000398- Patch #1462222: Fix Tix.Grid.

401
Skip Montanaro262fb922006-04-21 02:31:07 +0000402- The pstats.Stats class accepts an optional stream keyword argument to
403 direct output to an alternate file-like object.
404
Anthony Baxter51bcb682006-04-05 14:51:42 +0000405Build
406-----
407
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000408- The Makefile now has a reindent target, which runs reindent.py on
409 the library.
410
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000411- Patch #1470875: Building Python with MS Free Compiler
412
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000413- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000414
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000415- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
416 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000417 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000418 CXX from --with-cxx-main, see description in README.
419
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000420- Patch #1429775: Link extension modules with the shared libpython.
421
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000422- Fixed a libffi build problem on MIPS systems.
423
Tim Peters8931ff12006-05-13 23:28:20 +0000424- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
425 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
426 and "%zu" for unsigned integers of type ``size_t``.
427
Anthony Baxter51bcb682006-04-05 14:51:42 +0000428Tests
429-----
430
Nick Coghlanda2268f2006-04-24 04:37:15 +0000431- test_contextlib now checks contextlib.nested can cope with exceptions
432 being raised and caught inside exit handlers.
433
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000434- test_cmd_line now checks operation of the -m and -c command switches
435
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000436- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
437 it separately and by hand. It also wasn't cleaning up its changes to
438 the current Decimal context.
439
Thomas Woutersabd08882006-04-26 15:53:30 +0000440- regrtest.py now has a -M option to run tests that test the new limits of
441 containers, on 64-bit architectures. Running these tests is only sensible
442 on 64-bit machines with more than two gigabytes of memory. The argument
443 passed is the maximum amount of memory for the tests to use.
444
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +0000445Tools
446-----
447
448- Added the Python benchmark suite pybench to the Tools/ directory;
449 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000451Documentation
452-------------
453
Tim Petersb06d28c2006-05-12 01:57:59 +0000454- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
455
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000456- PEP 343: Added Context Types section to the library reference
457 and attempted to bring other PEP 343 related documentation into
458 line with the implementation and/or python-dev discussions.
459
Tim Peters8dc73d22006-04-24 02:03:16 +0000460- Bug #1337990: clarified that ``doctest`` does not support examples
461 requiring both expected output and an exception.
Anthony Baxter51bcb682006-04-05 14:51:42 +0000462

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000464What's New in Python 2.5 alpha 1?
465=================================
466
Anthony Baxterebed3f62006-04-03 15:03:44 +0000467*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000468
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000469Core and builtins
470-----------------
471
Nick Coghlan43832302006-04-23 17:04:07 +0000472- PEP 338: -m command line switch now delegates to runpy.run_module
473 allowing it to support modules in packages and zipfiles
474
Martin v. Löwisc661b882006-04-20 04:54:23 +0000475- On Windows, .DLL is not an accepted file name extension for
476 extension modules anymore; extensions are only found if they
477 end in .PYD.
478
Martin v. Löwisea62d252006-04-03 10:56:49 +0000479- Bug #1421664: sys.stderr.encoding is now set to the same value as
480 sys.stdout.encoding.
481
Neal Norwitz92e212f2006-04-03 04:48:37 +0000482- __import__ accepts keyword arguments.
483
Georg Brandlccadf842006-03-31 18:54:53 +0000484- Patch #1460496: round() now accepts keyword arguments.
485
Anthony Baxter262c00a2006-03-30 10:53:17 +0000486- Fixed bug #1459029 - unicode reprs were double-escaped.
487
Hye-Shik Changd478f342006-03-23 12:32:36 +0000488- Patch #1396919: The system scope threads are reenabled on FreeBSD
489 5.4 and later versions.
490
Neal Norwitze98ccf62006-03-23 05:39:47 +0000491- Bug #1115379: Compiling a Unicode string with an encoding declaration
492 now gives a SyntaxError.
493
Georg Brandlabd1ff82006-03-18 07:59:59 +0000494- Previously, Python code had no easy way to access the contents of a
495 cell object. Now, a ``cell_contents`` attribute has been added
496 (closes patch #1170323).
497
Tim Peterscf79aac2006-03-16 01:14:46 +0000498- Patch #1123430: Python's small-object allocator now returns an arena to
499 the system ``free()`` when all memory within an arena becomes unused
500 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
501 freed. Some applications will see a drop in virtual memory size now,
502 especially long-running applications that, from time to time, temporarily
503 use a large number of small objects. Note that when Python returns an
504 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000505 platform C library will in turn return that memory to the operating system.
506 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000507 appears to be effective at least on Microsoft C and gcc-based systems.
508 Thanks to Evan Jones for hard work and patience.
509
Georg Brandl533ff6f2006-03-08 18:09:27 +0000510- Patch #1434038: property() now uses the getter's docstring if there is
511 no "doc" argument given. This makes it possible to legitimately use
512 property() as a decorator to produce a read-only property.
513
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000514- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
515 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
516 of requiring an int or long in slicing and a few other contexts, enabling
517 other objects (e.g. Numeric Python's integers) to be used as slice indices.
518
Neal Norwitz995acdf2006-03-07 05:01:00 +0000519- Fixed various bugs reported by Coverity's Prevent tool.
520
Brett Cannonbf364092006-03-01 04:25:17 +0000521- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
522 new exception base class, BaseException, which has a new message attribute.
523 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
524 Raising a string exception now raises a DeprecationWarning.
525
Thomas Woutersfb609f42006-02-28 16:37:25 +0000526- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
527 explicitly relative, using 'from .module import name' to mean 'from the same
528 package as this module is in. Imports without dots still default to the
529 old relative-then-absolute, unless 'from __future__ import
530 absolute_import' is used.
531
Brett Cannona7446e32006-02-27 23:39:10 +0000532- Properly check if 'warnings' raises an exception (usually when a filter set
533 to "error" is triggered) when raising a warning for raising string
534 exceptions.
535
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000536- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000537 The name was removed from Include/code.h.
538
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000539- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000540
Guido van Rossum1968ad32006-02-25 22:38:04 +0000541- Patch 1433928:
542 - The copy module now "copies" function objects (as atomic objects).
543 - dict.__getitem__ now looks for a __missing__ hook before raising
544 KeyError.
545
Tim Peters84ef21c2006-02-28 20:39:06 +0000546- PEP 343: with statement implemented. Needs ``from __future__ import
547 with_statement``. Use of 'with' as a variable will generate a warning.
548 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000549 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000550 The following objects have __context__ methods:
551 - The built-in file type.
552 - The thread.LockType type.
553 - The following types defined by the threading module:
554 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
555 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000556
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000557- Fix the encodings package codec search function to only search
558 inside its own package. Fixes problem reported in patch #1433198.
559
560 Note: Codec packages should implement and register their own
561 codec search function. PEP 100 has the details.
562
Tim Peters9ea89d22006-06-04 03:26:02 +0000563- PEP 353: Using ``Py_ssize_t`` as the index type.
564
565- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
566 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
567 now allow Python to make use of memory blocks exceeding 2**32 bytes for
568 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
569 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000570
Neal Norwitzfc76d632006-01-10 06:03:13 +0000571- Patch #1400181, fix unicode string formatting to not use the locale.
572 This is how string objects work. u'%f' could use , instead of .
573 for the decimal point. Now both strings and unicode always use periods.
574
Neal Norwitz671b9e32006-01-09 07:07:12 +0000575- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
576 configure would break checking curses.h.
577
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000578- Bug #959576: The pwd module is now builtin. This allows Python to be
579 built on UNIX platforms without $HOME set.
580
Neal Norwitzc10978f2005-12-19 06:07:16 +0000581- Bug #1072182, fix some potential problems if characters are signed.
582
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000583- Bug #889500, fix line number on SyntaxWarning for global declarations.
584
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000585- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
586
Neal Norwitze7214a12005-12-18 05:03:17 +0000587- Support for converting hex strings to floats no longer works.
588 This was not portable. float('0x3') now raises a ValueError.
589
Barry Warsaw2a38a862005-12-18 01:27:35 +0000590- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000591 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000592 is now displayed in interactive prompt banner.
593
Georg Brandlfa166682005-12-17 21:45:17 +0000594- Implementation of PEP 341 - Unification of try/except and try/finally.
595 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000596 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000597
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000598- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
599 now encodes backslash correctly.
600
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000601- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
602
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000603- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000604 and long longs.
605
Neal Norwitz67715f02005-11-09 06:59:35 +0000606- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000607 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000608 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000609
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000610- Replaced most Unicode charmap codecs with new ones using the
611 new Unicode translate string feature in the builtin charmap
612 codec; the codecs were created from the mapping tables available
613 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
614 encodings now include a mapping for the Apple logo)
615
Tim Peterse3547fd2005-12-16 23:13:57 +0000616- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000617
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000618- Sped up some Unicode operations.

Martin v. Löwisbd260da2006-02-26 19:42:26 +0000620- A new AST parser implementation was completed. The abstract
621 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000622 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000623
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000624- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000625 The following code now raises a SyntaxError: foo(a = i for i in range(10))
626
Neal Norwitz708e51a2005-10-03 04:48:15 +0000627- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
628
Neal Norwitz11bd1192005-10-03 00:54:56 +0000629- SF Bug #887946: fix segfault when redirecting stdin from a directory.
630 Provide a warning when a directory is passed on the command line.
631
Neal Norwitz40d37812005-10-02 01:48:49 +0000632- Fix segfault with invalid coding.
633
634- SF bug #772896: unknown encoding results in MemoryError.
635
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000636- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000637 supported a __len__() method which evaluated to False when the iterator
638 was empty.
639
Guido van Rossum630db602005-09-20 18:49:54 +0000640- On 64-bit platforms, when __len__() returns a value that cannot be
641 represented as a C int, raise OverflowError.
642
Skip Montanarof8948ca2005-09-19 03:54:46 +0000643- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000644 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000645
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000646- SF bug #893549: parsing keyword arguments was broken with a few format
647 codes.
648
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000649- Changes donated by Elemental Security to make it work on AIX 5.3
650 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
651 bug #105470: test_pwd fails on 64bit system (Opteron).
652
Guido van Rossum539c6622005-09-14 17:49:54 +0000653- Changes donated by Elemental Security to make it work on HP-UX 11 on
654 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
655
Georg Brandl4550b8d2005-08-26 06:43:52 +0000656- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000657 (fixes bug #1119418).
658
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000659- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
660
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000661- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
662 exceptions that cause a function to exit.
663
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000664- The implementation of set() and frozenset() was revised to use its
665 own internal data structure. Memory consumption is reduced by 1/3
666 and there are modest speed-ups as well. The API is unchanged.
667
Tim Petersde7990b2005-07-17 23:45:23 +0000668- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
669
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000670- SF bug #1229429: PyObject_CallMethod failed to decrement some
671 reference counts in some error exit cases.
672
Tim Petersecc6e6a2005-07-10 22:30:55 +0000673- SF bug #1185883: Python's small-object memory allocator took over
674 a block managed by the platform C library whenever a realloc specified
675 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000676 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000677 portable way to copy data from the C-managed block into Python's
678 small-object space without risking a memory fault. Python's small-object
679 realloc now leaves such blocks under the control of the platform C
680 realloc.
681
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000682- SF bug #1232517: An overflow error was not detected properly when
683 attempting to convert a large float to an int in os.utime().
684
Raymond Hettinger3296e692005-06-29 23:29:56 +0000685- SF bug #1224347: hex longs now print with lowercase letters just
686 like their int counterparts.
687
Michael W. Hudson188d4362005-06-20 16:52:57 +0000688- SF bug #1163563: the original fix for bug #1010677 ("thread Module
689 Breaks PyGILState_Ensure()") broke badly in the case of multiple
690 interpreter states; back out that fix and do a better job (see
691 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
692 for a longer write-up of the problem).
693
Michael W. Hudsondf888462005-06-03 14:41:55 +0000694- SF patch #1180995: marshal now uses a binary format by default when
695 serializing floats.
696
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000697- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
698 the routines that promise to produce IEEE 754 binary representations
699 of floats now simply copy bytes around.
700
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000701- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
702 278.
703
Brett Cannonc3647ac2005-04-26 03:45:26 +0000704- patch #1109424: int, long, float, complex, and unicode now check for the
705 proper magic slot for type conversions when subclassed. Previously the
706 magic slot was ignored during conversion. Semantics now match the way
707 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000708 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000709 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000710 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000711
Barry Warsawc8d907c2005-04-19 23:43:40 +0000712- Descriptors defined in C with a PyGetSetDef structure, where the setter is
713 NULL, now raise an AttributeError when attempting to set or delete the
714 attribute. Previously a TypeError was raised, but this was inconsistent
715 with the equivalent pure-Python implementation.
716
Michael W. Hudson774479c2005-04-18 08:46:17 +0000717- It is now safe to call PyGILState_Release() before
718 PyEval_InitThreads() (note that if there is reason to believe there
719 are multiple threads around you still must call PyEval_InitThreads()
720 before using the Python API; this fix is for extension modules that
721 have no way of knowing if Python is multi-threaded yet).
722
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000723- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
724 disabled caused a crash.
725
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000726- Bug #1165306: instancemethod_new allowed the creation of a method
727 with im_class == im_self == NULL, which caused a crash when called.
728
Tim Petersecc6e6a2005-07-10 22:30:55 +0000729- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000730 fixes the crash seen in bug #1165761
731
Raymond Hettinger96229b12005-03-11 06:49:40 +0000732- Added two new builtins, any() and all().
733
Brett Cannon409d8f22005-03-05 06:47:57 +0000734- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000735 (e.g., ``class C(): pass`` is no longer a syntax error).
736 Patch #1176012 added support to the 'parser' module and 'compiler' package
737 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000738
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000739- Patch #1115086: Support PY_LONGLONG in structmember.
740
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000741- Bug #1155938: new style classes did not check that __init__() was
742 returning None.
743
Tim Petersecc6e6a2005-07-10 22:30:55 +0000744- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000745 ('\') with a specific error message.
746
Martin v. Löwisff232d72005-03-03 09:24:38 +0000747- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
748
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000749- Bug #1124295: the __name__ attribute of file objects was
750 inadvertently made inaccessible in restricted mode.
751
Tim Petersecc6e6a2005-07-10 22:30:55 +0000752- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000753 an ferror() call.
754
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000755- min() and max() now support key= arguments with the same meaning as in
756 list.sort().
757
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000758- The peephole optimizer now performs simple constant folding in expressions:
759 (2+3) --> (5).
760
Raymond Hettingera422c342005-01-11 03:03:27 +0000761- set and frozenset objects can now be marshalled. SF #1098985.
762
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000763- Bug #1077106: Poor argument checking could cause memory corruption
764 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000765
Jeremy Hyltonab630502005-02-04 18:44:06 +0000766- The parser did not complain about future statements in illegal
767 positions. It once again reports a syntax error if a future
768 statement occurs after anything other than a doc string.
769
Neil Schemenauercf52c072005-08-12 17:34:58 +0000770- Change the %s format specifier for str objects so that it returns a
771 unicode instance if the argument is not an instance of basestring and
772 calling __str__ on the argument returns a unicode instance.
773
Tim Petersf4e69282006-02-27 17:15:31 +0000774- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
775 current thread state when the auto-GIL-state machinery knows about
776 it (since the thread state is being deleted, continuing to remember it
777 can't help, but can hurt if another thread happens to get created with
778 the same thread id).
779
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000780Extension Modules
781-----------------
782

797
798- The following modules were removed: regsub, reconvert, regex, regex_syntax.
799
800- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +0000801 is deprecated. The undocumented re.engine variable no longer exists.
802

804 SS2 (single-shift 2) escape sequences correctly.
805
Martin v. Löwis480f1bb2006-03-09 23:38:20 +0000806- The unicodedata module was updated to the 4.1 version of the Unicode
807 database. The 3.2 version is still available as unicodedata.db_3_2_0
808 for applications that require this specific version (such as IDNA).
809
Neal Norwitzb62c4332006-03-04 18:35:47 +0000810- The timing module is no longer built by default. It was deprecated
811 in PEP 4 in Python 2.0 or earlier.
812
Guido van Rossum1968ad32006-02-25 22:38:04 +0000813- Patch 1433928: Added a new type, defaultdict, to the collections module.
814 This uses the new __missing__ hook behavior added to dict (see above).
815
Georg Brandldbd83392006-02-20 09:42:33 +0000816- Bug #854823: socketmodule now builds on Sun platforms even when
817 INET_ADDRSTRLEN is not defined.
818
Georg Brandlf4f44152006-02-18 22:29:33 +0000819- Patch #1393157: os.startfile() now has an optional argument to specify
820 a "command verb" to invoke on the file.
821
Neal Norwitz082b2df2006-02-07 07:04:46 +0000822- Bug #876637, prevent stack corruption when socket descriptor
823 is larger than FD_SETSIZE.
824
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +0000825- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
826 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
827 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
828
Martin v. Löwis57a34e82006-02-04 19:12:37 +0000829- Patch #1422385: The nis module now supports access to domains other
830 than the system default domain.
831
Martin v. Löwis14694662006-02-03 12:54:16 +0000832- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
833 are reported, the limit on path name lengths is removed, and stat reports
834 WindowsError now (instead of OSError).
835

911 the request code argument, which results in more C-like behaviour
912 for large or negative values.
913
Tim Petersecc6e6a2005-07-10 22:30:55 +0000914- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

968-------
969
Nick Coghlan43832302006-04-23 17:04:07 +0000970- PEP 338: new module runpy defines a run_module function to support
971 executing modules which provide access to source code or a code object
972 via the PEP 302 import mechanisms.

982 in attribute values.
983
Anthony Baxterc51ee692006-04-01 00:57:31 +0000984- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000985 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000986 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000987 module will not be built.
988
Tim Petersc17976e2006-04-01 00:26:53 +0000989- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
990 aren't officially supported here, and trying to use them will probably
991 raise an exception some day. But dicts have been allowed, and "mostly
992 worked", so support for them won't go away without warning.
993
Georg Brandl338ef7d2006-03-31 18:42:16 +0000994- Bug #1445068: getpass.getpass() can now be given an explicit stream

1012
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001013- email 4.0 package now integrated. This is largely the same as the email 3.0
1014 package that was included in Python 2.3, except that PEP 8 module names are
1015 now used (e.g. mail.message instead of email.Message). The MIME classes
1016 have been moved to a subpackage (e.g. email.mime.text instead of
1017 email.MIMEText). The old names are still supported for now. Several
1018 deprecated Message methods have been removed and lots of bugs have been
1019 fixed. More details can be found in the email package documentation.
1020
Walter Dörwald40108c92006-03-27 08:15:44 +00001021- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1022 (a subclass of tuple) that provides incremental decoders and encoders
1023 (a way to use stateful codecs without the stream API). Python functions
1024 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1025 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1026 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001027
Walter Dörwald067db482006-03-15 22:17:27 +00001028- Patch #1359365: Calling next() on a closed StringIO.String object raises
1029 a ValueError instead of a StopIteration now (like file and cString.String do).
1030 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1031 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001032

Tim Peterse3547fd2005-12-16 23:13:57 +00001105 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1106 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1107 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1108 Ronald L. Rivest offered this advice for Python:
1109
1110 "The consensus of researchers in this area (at least as
1111 expressed at the NIST Hash Function Workshop 10/31/05),
1112 is that SHA-256 is a good choice for the time being, but
1113 that research should continue, and other alternatives may
1114 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001115
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001116- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandlb9256022005-08-24 18:46:39 +00001162- Patch #1062060: urllib.urlretrieve() now raises a new exception, named
1163 ContentTooShortException, when the actually downloaded size does not
1164 match the Content-Length header.
1165
Martin v. Löwis0a5d4a22005-08-24 14:55:22 +00001166- Bug #1121494: distutils.dir_utils.mkpath now accepts Unicode strings.
1167
Martin v. Löwis56066d22005-08-24 07:38:12 +00001168- Bug #1178484: Return complete lines from codec stream readers
1169 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001170 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00001171

1177 to ntpath, macpath, os2emxpath and riscospath.
1178
Guido van Rossum755149f2005-07-27 00:00:44 +00001179- Fix a problem in Tkinter introduced by SF patch #869468: delete bogus
1180 __hasattr__ and __delattr__ methods on class Tk that were breaking
1181 Tkdnd.
1182
Georg Brandl5dbda752005-07-17 20:27:41 +00001183- Bug #1015140: disambiguated the term "article id" in nntplib docs and
1184 docstrings to either "article number" or "message id".
1185
Georg Brandla4a8b822005-07-15 09:13:21 +00001186- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
1187 parameter, but uses the usual "kwargs=None".
1188
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001189- textwrap now processes text chunks at O(n) speed instead of O(n**2).
Raymond Hettinger8bfa8932005-07-15 06:53:35 +00001190 Patch #1209527 (Contributed by Connelly).
1191
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00001192- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
1193 to W3C name (404 -> 'Not Found'). RFE #1216944.
1194
Georg Brandl9e43acf2005-07-04 17:16:07 +00001195- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1196 as this can cause problems with apps closing all file descriptors.
1197
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001198- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001199 it can be missing in embedded interpreters
Georg Brandl5284b532005-06-26 22:54:58 +00001200
Georg Brandl2f210b62005-06-26 22:09:06 +00001201- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
1202
Georg Brandlfbff1bc2005-06-26 21:36:25 +00001203- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
1204 error messages.
1205
Georg Brandl379f99d2005-06-26 21:09:38 +00001206- Bug #1108948: Cookie.py produced invalid JavaScript code.
1207
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00001208- The tokenize module now detects and reports indentation errors.
1209 Bug #1224621.
1210
Raymond Hettinger68c04532005-06-10 11:05:19 +00001211- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001212 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001213 the generate_tokens() function now accepts a callable argument that
1214 terminates by raising StopIteration.
1215
Georg Brandl9166e1a2005-06-04 09:20:03 +00001216- Bug #1196315: fix weakref.WeakValueDictionary constructor.
1217
Georg Brandl268e61c2005-06-03 14:28:50 +00001218- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
1219 component of the path.
1220
Skip Montanaro174dd222005-05-14 20:54:16 +00001221- Patch #1120353: The xmlrpclib module provides better, more transparent,
1222 support for datetime.{datetime,date,time} objects. With use_datetime set
1223 to True, applications shouldn't have to fiddle with the DateTime wrapper
1224 class at all.
1225
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001226- distutils.commands.upload was added to support uploading distribution
1227 files to PyPI.
1228
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001229- distutils.commands.register now encodes the data as UTF-8 before posting
1230 them to PyPI.
1231
Raymond Hettinger267b8682005-03-27 10:47:39 +00001232- decimal operator and comparison methods now return NotImplemented
1233 instead of raising a TypeError when interacting with other types. This
1234 allows other classes to implement __radd__ style methods and have them
1235 work as expected.
1236
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001237- Bug #1163325: Decimal infinities failed to hash. Attempting to
1238 hash a NaN raised an InvalidOperation instead of a TypeError.
1239
Tim Petersecc6e6a2005-07-10 22:30:55 +00001240- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001241 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1242
Martin v. Löwis00a73e72005-03-04 19:40:34 +00001243- Patch #1043890: Add extractall method to tarfile.

1246 to build.
1247
Martin v. Löwis637431b2005-03-03 23:12:42 +00001248- Patch #1103407: Properly deal with tarfile iterators when untarring

Martin v. Löwisa4dac402005-03-03 11:39:45 +00001252 profile.py if available.
1253
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00001254- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
1255

1270
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00001271- Patch #1049151: xdrlib now unpacks booleans as True or False.
1272
Raymond Hettingerbab41432005-02-05 01:31:19 +00001273- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1274
Guido van Rossumd0641422005-02-03 15:01:24 +00001275- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1276 disables recursive traversal through instance attributes, which can
1277 be exploited in various ways.
1278
Tim Peterse3547fd2005-12-16 23:13:57 +00001279- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001280 flags on the HTTP listening socket.
1281
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001282- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1283 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1284
Tim Peterse3547fd2005-12-16 23:13:57 +00001285- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001286 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1287
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001288- Bug #1110478: Revert os.environ.update to do putenv again.
1289
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001290- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1291
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001292- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1293
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001294- Enhancements to the csv module:
1295
1296 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001297 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001298 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001299 + Dialect parameter parsing has been re-implemented to improve error
1300 reporting.
1301 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1302 dictates.
1303 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001304 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001305 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001306 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1307 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001308 + reader now allows \r characters to be quoted (previously it only allowed
1309 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001310 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001311 + Dialect classes passed to the module are no longer instantiated by
1312 the module before being parsed (the former validation scheme required
1313 this, but the mechanism was unreliable).
1314 + The dialect registry now contains instances of the internal
1315 C-coded dialect type, rather than references to python objects.
1316 + the internal c-coded dialect type is now immutable.
1317 + register_dialect now accepts the same keyword dialect specifications
1318 as the reader and writer, allowing the user to register dialects
1319 without first creating a dialect class.
1320 + a configurable limit to the size of parsed fields has been added -
1321 previously, an unmatched quote character could result in the entire
1322 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001323 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001324 the parser field size limit (returning the former limit). The initial
1325 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001326 + A line_num attribute has been added to the reader object, which tracks
1327 the number of lines read from the source iterator. This is not
1328 the same as the number of records returned, as records can span
1329 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001330 + reader and writer objects were not being registered with the cyclic-GC.
1331 This has been fixed.
1332
Brett Cannone6539c42005-01-08 02:43:53 +00001333- _DummyThread objects in the threading module now delete self.__block that is
1334 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1335 lock primitives tend to be limited in number and thus should not be wasted on
1336 a _DummyThread object. Fixes bug #1089632.
1337
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001338- The imghdr module now detects Exif files.
1339
Raymond Hettinger6065d322004-12-20 23:51:53 +00001340- StringIO.truncate() now correctly adjusts the size attribute.
1341 (Bug #951915).
1342
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001343- locale.py now uses an updated locale alias table (built using
1344 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1345 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001346 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001347
Raymond Hettinger3557f422004-12-07 12:02:02 +00001348- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1349
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001350- the pickle module no longer accepts the deprecated None option in the
1351 args tuple returned by __reduce__().
1352
Brett Cannon84667c02004-12-07 03:25:18 +00001353- optparse now optionally imports gettext. This allows its use in setup.py.
1354
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001355- the pickle module no longer uses the deprecated bin parameter.
1356
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001357- the shelve module no longer uses the deprecated binary parameter.
1358
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001359- the pstats module no longer uses the deprecated ignore() method.
1360
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001361- the filecmp module no longer uses the deprecated use_statcache argument.
1362
Raymond Hettinger664347b2004-12-04 21:21:53 +00001363- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1364 extended or overridden by subclasses. Formerly, the subclassed method would
1365 be ignored by the rest of the module. (Bug #1078905).
1366
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001367- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001368 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001369
Walter Dörwald36733692004-12-22 12:50:50 +00001370- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1371 once when a size argument is given. This prevents a buffer overflow in the
1372 tokenizer with very long source lines.
1373
Barry Warsaw538561e2006-01-01 21:48:54 +00001374- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1375 immediately after creating the object, without any intervening
1376 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001377
Skip Montanaro05885812005-01-16 20:48:27 +00001378- The reconvert.quote function can now emit triple-quoted strings. The
1379 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001380
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001381- ``UserString.MutableString`` now supports negative indices in
1382 ``__setitem__`` and ``__delitem__``
1383
Greg Ward40407942005-03-05 02:53:17 +00001384- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1385 correctly.
1386
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001387- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1388 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1389 character even if the user has passed a size parameter to get a proper
1390 line ending. Remove the special handling of a "\r\n" that has been split
1391 between two lines.
1392
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001393- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1394 about illegal code points. The codec now supports PEP 293 style error
1395 handlers.
1396
Walter Dörwald78a78b02005-09-01 12:04:29 +00001397- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001398 from the input stream, so that the output is a byte string in the correct
1399 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001400
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001401- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1402 considering it exactly like a '*'.
1403
Walter Dörwald007f8df2005-10-09 19:42:27 +00001404- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1405 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001406
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001407- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1408
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001409- Patch #1413711: Certain patterns of differences were making difflib
1410 touch the recursion limit.
1411
Walter Dörwald58917a62006-03-31 15:26:22 +00001412- Bug #947906: An object oriented interface has been added to the calendar
1413 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001414 called as a script (e.g. via ``python -mcalendar``). Localized month and
1415 weekday names can be ouput (even if an exotic encoding is used) using

1419-----
1420
Neal Norwitz602d3392006-03-31 08:21:40 +00001421- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1422 by using -mieee gcc option.
1423

1425
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001426- Build support for Win64-AMD64 was added.
1427
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001428- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1429
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001430- Patch #881820: look for openpty and forkpty also in libbsd.
1431
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001432- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1433 The zlib module is now builtin on Windows.
1434
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001435- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1436
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001437- Bug #1189330: configure did not correctly determine the necessary
1438 value of LINKCC if python was built with GCC 4.0.
1439
Trent Mick8321b422005-07-26 02:29:21 +00001440- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1441 vulnerability in zlib 1.2.1 and 1.2.2.
1442
Brett Cannon08cd5982005-04-24 22:26:38 +00001443- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1444 flags that change binary compatibility. Changes were also made to
1445 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001446 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001447
Bob Ippolitoed233462005-03-29 13:47:59 +00001448- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1449 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1450 no longer exists). This configure patch makes things right.
1451
Martin v. Löwise2713be2005-03-08 15:03:08 +00001452- Bug #1158607: Build with --disable-unicode again.
1453
Brett Cannon46d96232005-02-16 00:07:19 +00001454- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1455 defined. Discovered as a result of not being able to build on OS X.
1456
Brett Cannon516592f2004-12-07 00:42:59 +00001457- setup.py now uses the directories specified in LDFLAGS using the -L option
1458 and in CPPFLAGS using the -I option for adding library and include
1459 directories, respectively, for compiling extension modules against. This has
1460 led to the core being compiled using the values in CPPFLAGS. It also removes
1461 the need for the special-casing of both DarwinPorts and Fink for darwin since
1462 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1463 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1464 Fink, ``-I/opt/local/include`` for DarwinPorts).
1465
Brett Cannon43802422005-02-10 20:48:03 +00001466- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1467 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1468 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1469 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001471C API
1472-----
1473
Tim Petersc9d78aa2006-03-26 23:27:58 +00001474- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1475 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1476 is obtained via the ``PyObject_`` family, it must be released via the
1477 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1478 always been officially true, but when Python's small-object allocator was
1479 introduced, an attempt was made to cater to a few extension modules
1480 discovered at the time that obtained memory via ``PyObject_New`` but
1481 released it via ``PyMem_DEL``. It's years later, and if such code still
1482 exists it will fail now (probably with segfaults, but calling wrong
1483 low-level memory management functions can yield many symptoms).
1484
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001485- Added a C API for set and frozenset objects.
1486
Raymond Hettinger66517482004-12-03 11:45:13 +00001487- Removed PyRange_New().
1488
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001489- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1490 mapping argument now. This string is used as a mapping table. Byte values
1491 greater than the length of the string and 0xFFFE are treated as undefined
1492 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00001498- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001499
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001500- Patch #1276356: New resource "urlfetch" is implemented. This enables
1501 even impatient people to run tests that require remote files.
