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 Cannon22565aa2006-06-09 22:31:23 +000015- Bug #532646: object.__call__() will continue looking for the __call__
16 attribute on objects until one without one is found. This leads to recursion
17 when you take a class and set its __call__ attribute to an instance of the
18 class. Originally fixed for classic classes, but this fix is for new-style.
19 Removes the infinite_rec_3 crasher.
20
Georg Brandl24250812006-06-09 18:45:48 +000021- The string and unicode methods startswith() and endswith() now accept
22 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
23
Brett Cannonde3b0522006-06-08 17:00:45 +000024- Buffer objects, at the C level, never used the char buffer
25 implementation even when the char buffer for the wrapped object was
26 explicitly requested (originally returned the read or write buffer).
27 Now a TypeError is raised if the char buffer is not present but is
28 requested.
29
Georg Brandlddbaa662006-06-04 21:56:52 +000030- Patch #1346214: Statements like "if 0: suite" are now again optimized
31 away like they were in Python 2.4.
32
Georg Brandlb7c8f542006-05-27 12:30:25 +000033- Builtin exceptions are now full-blown new-style classes instead of
34 instances pretending to be classes, which speeds up exception handling
35 by about 80% in comparison to 2.5a2.
36
Martin v. Löwisd004fc82006-05-27 08:36:52 +000037- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
38 Unicode 4.1.
39
Georg Brandlf4ef1162006-05-26 18:03:31 +000040- Patch #921466: sys.path_importer_cache is now used to cache valid and
41 invalid file paths for the built-in import machinery which leads to
42 fewer open calls on startup.
43
Tim Peters696cf432006-05-24 21:10:40 +000044- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
45 of-2 bases. The largest speedup is for inputs with about 1000 decimal
46 digits. Conversion from non-power-of-2 bases remains quadratic-time in
47 the number of input digits (it was and remains linear-time for bases
48 2, 4, 8, 16 and 32).
49
Tim Petersb713ec22006-05-23 18:45:30 +000050- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
51 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
52 an integer close to ``sys.maxint``. This was repaired by patch
53 #1335972, which also gives a nice speedup.
54
Richard Jonescebbefc2006-05-23 18:28:17 +000055- Patch #1337051: reduced size of frame objects.
56
57- PyErr_NewException now accepts a tuple of base classes as its
58 "base" parameter.
59
Richard Jones7c88dcc2006-05-23 10:37:38 +000060- Patch #876206: function call speedup by retaining allocated frame
61 objects.
62
Georg Brandl7b90e162006-05-18 07:01:27 +000063- Bug #1462152: file() now checks more thoroughly for invalid mode
64 strings and removes a possible "U" before passing the mode to the
65 C library function.
66
Neal Norwitz1004a532006-05-15 07:17:23 +000067- Patch #1488312, Fix memory alignment problem on SPARC in unicode
68
Neal Norwitz373f0a72006-05-15 07:04:36 +000069- Bug #1487966: Fix SystemError with conditional expression in assignment
70
Martin v. Löwis879768d2006-05-11 13:28:43 +000071- WindowsError now has two error code attributes: errno, which carries
72 the error values from errno.h, and winerror, which carries the error
73 values from winerror.h. Previous versions put the winerror.h values
74 (from GetLastError()) into the errno attribute.
75
Martin v. Löwis77736712006-05-04 05:51:03 +000076- Patch #1475845: Raise IndentationError for unexpected indent.
77
Neal Norwitzc4edb0e2006-05-02 04:43:14 +000078- Patch #1479181: split open() and file() from being aliases for each other.
79
Tim Peters44bd9862006-06-01 13:49:23 +000080- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
81 methods were always silently ignored by dictionaries when comparing keys.
82 They are now passed through (except when using the C API function
83 ``PyDict_GetItem()``, whose semantics did not change).
84
85- Bug #1456209: In some obscure cases it was possible for a class with a
86 custom ``__eq__()`` method to confuse dict internals when class instances
87 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
88 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +000090Extension Modules
91-----------------
92
Brett Cannon6ee7d012006-06-08 16:23:04 +000093- Change binascii.hexlify to accept a read-only buffer instead of only a char
94 buffer and actually follow its documentation.
95
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +000096- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
97
Nick Coghlanc649ec52006-05-29 12:43:05 +000098- Patch #1478788 (modified version): The functional extension module has
99 been renamed to _functools and a functools Python wrapper module added.
100 This provides a home for additional function related utilities that are
101 not specifically about functional programming. See PEP 309.
102
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000103- Patch #1493701: performance enhancements for struct module.
104
Georg Brandl378d5922006-05-17 14:26:50 +0000105- Patch #1490224: time.altzone is now set correctly on Cygwin.
106
Georg Brandl8d3342b2006-05-16 07:38:27 +0000107- Patch #1435422: zlib's compress and decompress objects now have a
108 copy() method.
109
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000110- On Win32, os.listdir now supports arbitrarily-long Unicode path names
111 (up to the system limit of 32K characters).
112
113- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
114 As a result, these functions now raise WindowsError instead of OSError.
115
Tim Peters7a822da2006-05-25 21:50:17 +0000116- ``time.clock()`` on Win64 should use the high-performance Windows
117 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
118 Windows platforms).
119
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000120- Calling Tk_Init twice is refused if the first call failed as that
121 may deadlock.
122
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000123- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
124 accept it without potentially using an uninitialized pointer.
125
126- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
127 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
128 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000129
Gregory P. Smith372b5832006-06-05 18:48:21 +0000130- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000131 [pybsddb project SF patch number 1466734]
132
Gregory P. Smith372b5832006-06-05 18:48:21 +0000133- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
134 parameter is supplied. [SF pybsddb bug #1477863]
135
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000136- bsddb: the __len__ method of a DB object has been fixed to return correct
137 results. It could previously incorrectly return 0 in some cases.
138 Fixes SF bug 1493322 (pybsddb bug 1184012).
139
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000140- bsddb: the bsddb.dbtables Modify method now raises the proper error and
141 aborts the db transaction safely when a modifier callback fails.
142 Fixes SF python patch/bug #1408584.
143
Gregory P. Smith372b5832006-06-05 18:48:21 +0000144
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000145Library
146-------
147
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000148- The wsgiref package has been added to the standard library.
149
Nick Coghlan676725d2006-06-08 13:54:49 +0000150- The functions update_wrapper() and wraps() have been added to the functools
151 module. These make it easier to copy relevant metadata from the original
152 function when writing wrapper functions.
153
Tim Petersd6a9eef2006-06-05 01:48:21 +0000154- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
155 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000156
Martin v. Löwis3f767792006-06-04 19:36:28 +0000157- Patch #1359618: Speed up charmap encoder by using a trie structure
158 for lookup.
159
Tim Petersd609b1a2006-06-02 23:22:51 +0000160- The functions in the ``pprint`` module now sort dictionaries by key
161 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
162 if and only if its display required more than one line, although that
163 wasn't documented. The new behavior increases predictability; e.g.,
164 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
165
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000166- Patch #1497027: try HTTP digest auth before basic auth in urllib2
167 (thanks for J. J. Lee).
168
Georg Brandl2b330372006-05-28 20:23:12 +0000169- Patch #1496206: improve urllib2 handling of passwords with respect to
170 default HTTP and HTTPS ports.
171
George Yoshidaf3c65de2006-05-28 16:39:09 +0000172- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
173
Bob Ippolito7298f272006-05-23 18:43:47 +0000174- Patch #1281707: speed up gzip.readline.
175
Georg Brandlb89316f2006-05-17 15:51:16 +0000176- Patch #1180296: Two new functions were added to the locale module:
177 format_string() to get the effect of "format % items" but locale-aware,
178 and currency() to format a monetary number with currency sign.
179
Georg Brandle3a25832006-05-17 14:56:04 +0000180- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
181 and several features added, such as speed and geometry control.
182
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000183- Patch #1488881: add support for external file objects in bz2 compressed
184 tarfiles.
185
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000186- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
187 stdout arguments, making it possible to redirect input and output
188 for remote debugging.
189
190- Patch #1484695: Update the tarfile module to version 0.8. This fixes
191 a couple of issues, notably handling of long file names using the
192 GNU LONGNAME extension.
193
194- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
195 new flag when ``name`` is already the name of an option flag.
196
197- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
198 package.
199
200- Patch #1472854: make the rlcompleter.Completer class usable on non-
201 UNIX platforms.
202
203- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
204
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000205- Bug #1472827: correctly escape newlines and tabs in attribute values in
206 the saxutils.XMLGenerator class.
207

210-----
211
Georg Brandl66a0dbb2006-06-08 12:54:13 +0000212- Bug #1502728: Correctly link against librt library on HP-UX.
213
Martin v. Löwis222c5152006-06-03 07:37:13 +0000214- OpenBSD 3.9 is supported now.
215
Martin v. Löwisa43190b2006-05-22 09:15:18 +0000216- Patch #1492356: Port to Windows CE.
217
Neal Norwitz58e28882006-05-19 07:00:58 +0000218- Bug/Patch #1481770: Use .so extension for shared libraries on HP-UX for ia64.
219
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000220- Patch #1471883: Add --enable-universalsdk.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000236What's New in Python 2.5 alpha 2?
237=================================
238
239*Release date: 27-APR-2006*
240
241Core and builtins
242-----------------
243
Thomas Heller1b046642006-04-18 18:51:06 +0000244- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
245 by converting these apis from macros into exported functions again:
246
247 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
248 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
249 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
250 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
251 PyRun_String Py_CompileString
252
Martin v. Löwis45294a92006-04-18 06:24:08 +0000253- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
254
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000255- All uses of PyStructSequence_InitType have been changed to initialize
256 the type objects only once, even if the interpreter is initialized
257 multiple times.
258
Neal Norwitz61546162006-04-14 05:20:28 +0000259- Bug #1454485, array.array('u') could crash the interpreter. This was
260 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
261 to unicode when it didn't make sense. 'u#' now requires a unicode string.
262
263- Py_UNICODE is unsigned. It was always documented as unsigned, but
264 due to a bug had a signed value in previous versions.
265
Tim Peters3a5e8b12006-04-11 01:44:07 +0000266- Patch #837242: ``id()`` of any Python object always gives a positive
267 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
268 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000269 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000270 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000271
Tim Peters3a5e8b12006-04-11 01:44:07 +0000272 def __hash__(self):
273 return id(self) # WRONG
274
275 because a hash result must be a (short) Python int but it was always
276 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000277 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000278 was always usable as a hash value before this patch. That's no longer
279 necessarily so.
280
281- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000282 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000283 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000284 #1454844)
285
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000286- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
287 involving generators that have paused outside of any ``try`` or ``with``
288 blocks. (In 2.5a1, a paused generator that was part of a reference
289 cycle could not be garbage collected, regardless of whether it was
290 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000292Extension Modules
293-----------------
294
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000295- Patch #1191065: Fix preprocessor problems on systems where recvfrom
296 is a macro.
297
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000298- Bug #1467952: os.listdir() now correctly raises an error if readdir()
299 fails with an error condition.
300
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000301- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
302
303- Bug #1117761: bsddb.*open() no longer raises an exception when using
304 the cachesize parameter.
305
306- Bug #1149413: bsddb.*open() no longer raises an exception when using
307 a temporary db (file=None) with the 'n' flag to truncate on open.
308
309- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
310 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000311
Armin Rigoa9017c32006-04-19 11:50:27 +0000312- Patch #1062014: AF_UNIX sockets under Linux have a special
313 abstract namespace that is now fully supported.
314
Anthony Baxter51bcb682006-04-05 14:51:42 +0000315Library
316-------
317
Tim Peters711bf302006-04-25 03:31:36 +0000318- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
319 a doctest to be skipped (the code is not run, and the expected output
320 or exception is ignored).
321
Nick Coghlanda2268f2006-04-24 04:37:15 +0000322- Fixed contextlib.nested to cope with exceptions being raised and
323 caught inside exit handlers.
324
Greg Wardab05edc2006-04-23 03:47:58 +0000325- Updated optparse module to Optik 1.5.1 (allow numeric constants in
326 hex, octal, or binary; add ``append_const`` action; keep going if
327 gettext cannot be imported; added ``OptionParser.destroy()`` method;
328 added ``epilog`` for better help generation).

Tim Peters21fbd572006-04-21 21:18:10 +0000330- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
331 called from a thread spawned as a side effect of importing a module.
332
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000333- The pydoc module now supports documenting packages contained in
334 .zip or .egg files.
335
336- The pkgutil module now has several new utility functions, such
337 as ``walk_packages()`` to support working with packages that are either
338 in the filesystem or zip files.
339
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000340- The mailbox module can now modify and delete messages from
341 mailboxes, in addition to simply reading them. Thanks to Gregory
342 K. Johnson for writing the code, and to the 2005 Google Summer of
343 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000344
Tim Petersc7605f22006-04-17 21:12:33 +0000345- The ``__del__`` method of class ``local`` in module ``_threading_local``
346 returned before accomplishing any of its intended cleanup.

353
Anthony Baxtere29002c2006-04-12 12:07:31 +0000354- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
355 Windows. Bug #1469163.
356
Phillip J. Eby47032112006-04-11 01:07:43 +0000357- The warnings, linecache, inspect, traceback, site, and doctest modules
358 were updated to work correctly with modules imported from zipfiles or
359 via other PEP 302 __loader__ objects.
360
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000361- Patch #1467770: Reduce usage of subprocess._active to processes which
362 the application hasn't waited on.
363
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000364- Patch #1462222: Fix Tix.Grid.
365
Neal Norwitza31bf182006-04-09 03:35:43 +0000366- Fix exception when doing glob.glob('anything*/')
367
Skip Montanaro262fb922006-04-21 02:31:07 +0000368- The pstats.Stats class accepts an optional stream keyword argument to
369 direct output to an alternate file-like object.
370
Anthony Baxter51bcb682006-04-05 14:51:42 +0000371Build
372-----
373
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000374- The Makefile now has a reindent target, which runs reindent.py on
375 the library.
376
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000377- Patch #1470875: Building Python with MS Free Compiler
378
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000379- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000380
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000381- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
382 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000383 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000384 CXX from --with-cxx-main, see description in README.
385
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000386- Patch #1429775: Link extension modules with the shared libpython.
387
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000388- Fixed a libffi build problem on MIPS systems.
389
Tim Peters8931ff12006-05-13 23:28:20 +0000390- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
391 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
392 and "%zu" for unsigned integers of type ``size_t``.
393
Anthony Baxter51bcb682006-04-05 14:51:42 +0000394Tests
395-----
396
Nick Coghlanda2268f2006-04-24 04:37:15 +0000397- test_contextlib now checks contextlib.nested can cope with exceptions
398 being raised and caught inside exit handlers.
399
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000400- test_cmd_line now checks operation of the -m and -c command switches
401
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000402- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
403 it separately and by hand. It also wasn't cleaning up its changes to
404 the current Decimal context.
405
Thomas Woutersabd08882006-04-26 15:53:30 +0000406- regrtest.py now has a -M option to run tests that test the new limits of
407 containers, on 64-bit architectures. Running these tests is only sensible
408 on 64-bit machines with more than two gigabytes of memory. The argument
409 passed is the maximum amount of memory for the tests to use.

418-------------
419
Tim Petersb06d28c2006-05-12 01:57:59 +0000420- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
421
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000422- PEP 343: Added Context Types section to the library reference
423 and attempted to bring other PEP 343 related documentation into
424 line with the implementation and/or python-dev discussions.
425
Tim Peters8dc73d22006-04-24 02:03:16 +0000426- Bug #1337990: clarified that ``doctest`` does not support examples
427 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000430What's New in Python 2.5 alpha 1?
431=================================
432
Anthony Baxterebed3f62006-04-03 15:03:44 +0000433*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000434
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000435Core and builtins
436-----------------
437
Nick Coghlan43832302006-04-23 17:04:07 +0000438- PEP 338: -m command line switch now delegates to runpy.run_module
439 allowing it to support modules in packages and zipfiles
440
Martin v. Löwisc661b882006-04-20 04:54:23 +0000441- On Windows, .DLL is not an accepted file name extension for
442 extension modules anymore; extensions are only found if they
443 end in .PYD.
444
Martin v. Löwisea62d252006-04-03 10:56:49 +0000445- Bug #1421664: sys.stderr.encoding is now set to the same value as
446 sys.stdout.encoding.
447
Neal Norwitz92e212f2006-04-03 04:48:37 +0000448- __import__ accepts keyword arguments.
449
Georg Brandlccadf842006-03-31 18:54:53 +0000450- Patch #1460496: round() now accepts keyword arguments.
451
Anthony Baxter262c00a2006-03-30 10:53:17 +0000452- Fixed bug #1459029 - unicode reprs were double-escaped.
453
Hye-Shik Changd478f342006-03-23 12:32:36 +0000454- Patch #1396919: The system scope threads are reenabled on FreeBSD
455 5.4 and later versions.
456
Neal Norwitze98ccf62006-03-23 05:39:47 +0000457- Bug #1115379: Compiling a Unicode string with an encoding declaration
458 now gives a SyntaxError.
459
Georg Brandlabd1ff82006-03-18 07:59:59 +0000460- Previously, Python code had no easy way to access the contents of a
461 cell object. Now, a ``cell_contents`` attribute has been added
462 (closes patch #1170323).
463
Tim Peterscf79aac2006-03-16 01:14:46 +0000464- Patch #1123430: Python's small-object allocator now returns an arena to
465 the system ``free()`` when all memory within an arena becomes unused
466 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
467 freed. Some applications will see a drop in virtual memory size now,
468 especially long-running applications that, from time to time, temporarily
469 use a large number of small objects. Note that when Python returns an
470 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000471 platform C library will in turn return that memory to the operating system.
472 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000473 appears to be effective at least on Microsoft C and gcc-based systems.
474 Thanks to Evan Jones for hard work and patience.
475
Georg Brandl533ff6f2006-03-08 18:09:27 +0000476- Patch #1434038: property() now uses the getter's docstring if there is
477 no "doc" argument given. This makes it possible to legitimately use
478 property() as a decorator to produce a read-only property.
479
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000480- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
481 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
482 of requiring an int or long in slicing and a few other contexts, enabling
483 other objects (e.g. Numeric Python's integers) to be used as slice indices.
484
Neal Norwitz995acdf2006-03-07 05:01:00 +0000485- Fixed various bugs reported by Coverity's Prevent tool.
486
Brett Cannonbf364092006-03-01 04:25:17 +0000487- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
488 new exception base class, BaseException, which has a new message attribute.
489 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
490 Raising a string exception now raises a DeprecationWarning.
491
Thomas Woutersfb609f42006-02-28 16:37:25 +0000492- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
493 explicitly relative, using 'from .module import name' to mean 'from the same
494 package as this module is in. Imports without dots still default to the
495 old relative-then-absolute, unless 'from __future__ import
496 absolute_import' is used.
497
Brett Cannona7446e32006-02-27 23:39:10 +0000498- Properly check if 'warnings' raises an exception (usually when a filter set
499 to "error" is triggered) when raising a warning for raising string
500 exceptions.
501
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000502- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000503 The name was removed from Include/code.h.
504
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000505- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000506
Guido van Rossum1968ad32006-02-25 22:38:04 +0000507- Patch 1433928:
508 - The copy module now "copies" function objects (as atomic objects).
509 - dict.__getitem__ now looks for a __missing__ hook before raising
510 KeyError.
511
Tim Peters84ef21c2006-02-28 20:39:06 +0000512- PEP 343: with statement implemented. Needs ``from __future__ import
513 with_statement``. Use of 'with' as a variable will generate a warning.
514 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000515 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000516 The following objects have __context__ methods:
517 - The built-in file type.
518 - The thread.LockType type.
519 - The following types defined by the threading module:
520 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
521 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000522
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000523- Fix the encodings package codec search function to only search
524 inside its own package. Fixes problem reported in patch #1433198.
525
526 Note: Codec packages should implement and register their own
527 codec search function. PEP 100 has the details.
528
Tim Peters9ea89d22006-06-04 03:26:02 +0000529- PEP 353: Using ``Py_ssize_t`` as the index type.
530
531- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
532 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
533 now allow Python to make use of memory blocks exceeding 2**32 bytes for
534 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
535 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000536
Neal Norwitzfc76d632006-01-10 06:03:13 +0000537- Patch #1400181, fix unicode string formatting to not use the locale.
538 This is how string objects work. u'%f' could use , instead of .
539 for the decimal point. Now both strings and unicode always use periods.
540
Neal Norwitz671b9e32006-01-09 07:07:12 +0000541- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
542 configure would break checking curses.h.
543
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000544- Bug #959576: The pwd module is now builtin. This allows Python to be
545 built on UNIX platforms without $HOME set.
546
Neal Norwitzc10978f2005-12-19 06:07:16 +0000547- Bug #1072182, fix some potential problems if characters are signed.
548
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000549- Bug #889500, fix line number on SyntaxWarning for global declarations.
550
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000551- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
552
Neal Norwitze7214a12005-12-18 05:03:17 +0000553- Support for converting hex strings to floats no longer works.
554 This was not portable. float('0x3') now raises a ValueError.
555
Barry Warsaw2a38a862005-12-18 01:27:35 +0000556- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000557 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000558 is now displayed in interactive prompt banner.
559
Georg Brandlfa166682005-12-17 21:45:17 +0000560- Implementation of PEP 341 - Unification of try/except and try/finally.
561 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000562 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000563
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000564- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
565 now encodes backslash correctly.
566
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000567- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
568
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000569- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000570 and long longs.
571
Neal Norwitz67715f02005-11-09 06:59:35 +0000572- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000573 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000574 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000575
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000576- Replaced most Unicode charmap codecs with new ones using the
577 new Unicode translate string feature in the builtin charmap
578 codec; the codecs were created from the mapping tables available
579 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
580 encodings now include a mapping for the Apple logo)
581
Tim Peterse3547fd2005-12-16 23:13:57 +0000582- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000583
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000584- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000585
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000586- A new AST parser implementation was completed. The abstract
587 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000588 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000589
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000590- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000591 The following code now raises a SyntaxError: foo(a = i for i in range(10))
592
Neal Norwitz708e51a2005-10-03 04:48:15 +0000593- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
594
Neal Norwitz11bd1192005-10-03 00:54:56 +0000595- SF Bug #887946: fix segfault when redirecting stdin from a directory.
596 Provide a warning when a directory is passed on the command line.
597
Neal Norwitz40d37812005-10-02 01:48:49 +0000598- Fix segfault with invalid coding.
599
600- SF bug #772896: unknown encoding results in MemoryError.
601
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000602- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000603 supported a __len__() method which evaluated to False when the iterator
604 was empty.
605
Guido van Rossum630db602005-09-20 18:49:54 +0000606- On 64-bit platforms, when __len__() returns a value that cannot be
607 represented as a C int, raise OverflowError.
608
Skip Montanarof8948ca2005-09-19 03:54:46 +0000609- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000610 present).

Georg Brandl80bbf3f2005-09-14 19:38:29 +0000612- SF bug #893549: parsing keyword arguments was broken with a few format
613 codes.
614
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000615- Changes donated by Elemental Security to make it work on AIX 5.3
616 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
617 bug #105470: test_pwd fails on 64bit system (Opteron).
618
Guido van Rossum539c6622005-09-14 17:49:54 +0000619- Changes donated by Elemental Security to make it work on HP-UX 11 on
620 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
621
Georg Brandl4550b8d2005-08-26 06:43:52 +0000622- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000623 (fixes bug #1119418).
624
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000625- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
626
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000627- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
628 exceptions that cause a function to exit.
629
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000630- The implementation of set() and frozenset() was revised to use its
631 own internal data structure. Memory consumption is reduced by 1/3
632 and there are modest speed-ups as well. The API is unchanged.
633
Tim Petersde7990b2005-07-17 23:45:23 +0000634- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
635
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000636- SF bug #1229429: PyObject_CallMethod failed to decrement some
637 reference counts in some error exit cases.
638
Tim Petersecc6e6a2005-07-10 22:30:55 +0000639- SF bug #1185883: Python's small-object memory allocator took over
640 a block managed by the platform C library whenever a realloc specified
641 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000642 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000643 portable way to copy data from the C-managed block into Python's
644 small-object space without risking a memory fault. Python's small-object
645 realloc now leaves such blocks under the control of the platform C
646 realloc.
647
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000648- SF bug #1232517: An overflow error was not detected properly when
649 attempting to convert a large float to an int in os.utime().
650
Raymond Hettinger3296e692005-06-29 23:29:56 +0000651- SF bug #1224347: hex longs now print with lowercase letters just
652 like their int counterparts.
653
Michael W. Hudson188d4362005-06-20 16:52:57 +0000654- SF bug #1163563: the original fix for bug #1010677 ("thread Module
655 Breaks PyGILState_Ensure()") broke badly in the case of multiple
656 interpreter states; back out that fix and do a better job (see
657 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
658 for a longer write-up of the problem).
659
Michael W. Hudsondf888462005-06-03 14:41:55 +0000660- SF patch #1180995: marshal now uses a binary format by default when
661 serializing floats.
662
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000663- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
664 the routines that promise to produce IEEE 754 binary representations
665 of floats now simply copy bytes around.
666
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000667- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
668 278.
669
Brett Cannonc3647ac2005-04-26 03:45:26 +0000670- patch #1109424: int, long, float, complex, and unicode now check for the
671 proper magic slot for type conversions when subclassed. Previously the
672 magic slot was ignored during conversion. Semantics now match the way
673 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000674 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000675 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000676 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000677
Barry Warsawc8d907c2005-04-19 23:43:40 +0000678- Descriptors defined in C with a PyGetSetDef structure, where the setter is
679 NULL, now raise an AttributeError when attempting to set or delete the
680 attribute. Previously a TypeError was raised, but this was inconsistent
681 with the equivalent pure-Python implementation.
682
Michael W. Hudson774479c2005-04-18 08:46:17 +0000683- It is now safe to call PyGILState_Release() before
684 PyEval_InitThreads() (note that if there is reason to believe there
685 are multiple threads around you still must call PyEval_InitThreads()
686 before using the Python API; this fix is for extension modules that
687 have no way of knowing if Python is multi-threaded yet).
688
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000689- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
690 disabled caused a crash.
691
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000692- Bug #1165306: instancemethod_new allowed the creation of a method
693 with im_class == im_self == NULL, which caused a crash when called.
694
Tim Petersecc6e6a2005-07-10 22:30:55 +0000695- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000696 fixes the crash seen in bug #1165761
697
Raymond Hettinger96229b12005-03-11 06:49:40 +0000698- Added two new builtins, any() and all().
699
Brett Cannon409d8f22005-03-05 06:47:57 +0000700- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000701 (e.g., ``class C(): pass`` is no longer a syntax error).
702 Patch #1176012 added support to the 'parser' module and 'compiler' package
703 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000704
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000705- Patch #1115086: Support PY_LONGLONG in structmember.
706
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000707- Bug #1155938: new style classes did not check that __init__() was
708 returning None.
709
Tim Petersecc6e6a2005-07-10 22:30:55 +0000710- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000711 ('\') with a specific error message.
712
Martin v. Löwisff232d72005-03-03 09:24:38 +0000713- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
714
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000715- Bug #1124295: the __name__ attribute of file objects was
716 inadvertently made inaccessible in restricted mode.
717
Tim Petersecc6e6a2005-07-10 22:30:55 +0000718- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000719 an ferror() call.
720
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000721- min() and max() now support key= arguments with the same meaning as in
722 list.sort().
723
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000724- The peephole optimizer now performs simple constant folding in expressions:
725 (2+3) --> (5).
726
Raymond Hettingera422c342005-01-11 03:03:27 +0000727- set and frozenset objects can now be marshalled. SF #1098985.
728
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000729- Bug #1077106: Poor argument checking could cause memory corruption
730 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000731
Jeremy Hyltonab630502005-02-04 18:44:06 +0000732- The parser did not complain about future statements in illegal
733 positions. It once again reports a syntax error if a future
734 statement occurs after anything other than a doc string.
735
Neil Schemenauercf52c072005-08-12 17:34:58 +0000736- Change the %s format specifier for str objects so that it returns a
737 unicode instance if the argument is not an instance of basestring and
738 calling __str__ on the argument returns a unicode instance.
739
Tim Petersf4e69282006-02-27 17:15:31 +0000740- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
741 current thread state when the auto-GIL-state machinery knows about
742 it (since the thread state is being deleted, continuing to remember it
743 can't help, but can hurt if another thread happens to get created with
744 the same thread id).
745
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000746Extension Modules

763
764- The following modules were removed: regsub, reconvert, regex, regex_syntax.
765
766- re and sre were swapped, so help(re) provides full help. importing sre

770 SS2 (single-shift 2) escape sequences correctly.
771
Martin v. Löwis480f1bb2006-03-09 23:38:20 +0000772- The unicodedata module was updated to the 4.1 version of the Unicode
773 database. The 3.2 version is still available as unicodedata.db_3_2_0
774 for applications that require this specific version (such as IDNA).
775
Neal Norwitzb62c4332006-03-04 18:35:47 +0000776- The timing module is no longer built by default. It was deprecated
777 in PEP 4 in Python 2.0 or earlier.
778
Guido van Rossum1968ad32006-02-25 22:38:04 +0000779- Patch 1433928: Added a new type, defaultdict, to the collections module.
780 This uses the new __missing__ hook behavior added to dict (see above).
781
Georg Brandldbd83392006-02-20 09:42:33 +0000782- Bug #854823: socketmodule now builds on Sun platforms even when

784
Georg Brandlf4f44152006-02-18 22:29:33 +0000785- Patch #1393157: os.startfile() now has an optional argument to specify
786 a "command verb" to invoke on the file.
787
Neal Norwitz082b2df2006-02-07 07:04:46 +0000788- Bug #876637, prevent stack corruption when socket descriptor

792 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
793 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
794
Martin v. Löwis57a34e82006-02-04 19:12:37 +0000795- Patch #1422385: The nis module now supports access to domains other
796 than the system default domain.
797
Martin v. Löwis14694662006-02-03 12:54:16 +0000798- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
799 are reported, the limit on path name lengths is removed, and stat reports
800 WindowsError now (instead of OSError).
801

932
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000933Library
934-------
935
Nick Coghlan43832302006-04-23 17:04:07 +0000936- PEP 338: new module runpy defines a run_module function to support
937 executing modules which provide access to source code or a code object
938 via the PEP 302 import mechanisms.
939
Anthony Baxter93f5b932006-04-03 08:05:07 +0000940- The email module's parsedate_tz function now sets the daylight savings

948 in attribute values.
949
Anthony Baxterc51ee692006-04-01 00:57:31 +0000950- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +0000951 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +0000952 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +0000953 module will not be built.
954
Tim Petersc17976e2006-04-01 00:26:53 +0000955- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
956 aren't officially supported here, and trying to use them will probably
957 raise an exception some day. But dicts have been allowed, and "mostly
958 worked", so support for them won't go away without warning.
959
Georg Brandl338ef7d2006-03-31 18:42:16 +0000960- Bug #1445068: getpass.getpass() can now be given an explicit stream
961 argument to specify where to write the prompt.
962
Georg Brandl22ec80b2006-03-31 18:25:44 +0000963- Patch #1462313, bug #1443328: the pickle modules now can handle classes

978
Barry Warsaw4d90bbd2006-03-22 02:45:50 +0000979- email 4.0 package now integrated. This is largely the same as the email 3.0
980 package that was included in Python 2.3, except that PEP 8 module names are
981 now used (e.g. mail.message instead of email.Message). The MIME classes
982 have been moved to a subpackage (e.g. email.mime.text instead of
983 email.MIMEText). The old names are still supported for now. Several
984 deprecated Message methods have been removed and lots of bugs have been
985 fixed. More details can be found in the email package documentation.
986
Walter Dörwald40108c92006-03-27 08:15:44 +0000987- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
988 (a subclass of tuple) that provides incremental decoders and encoders
989 (a way to use stateful codecs without the stream API). Python functions
990 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
991 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
992 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +0000993
Walter Dörwald067db482006-03-15 22:17:27 +0000994- Patch #1359365: Calling next() on a closed StringIO.String object raises
995 a ValueError instead of a StopIteration now (like file and cString.String do).
996 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
997 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +0000998
Martin v. Löwis04824ce2006-03-10 21:26:16 +0000999- A regrtest option -w was added to re-run failed tests in verbose mode.

1072 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1073 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1074 Ronald L. Rivest offered this advice for Python:
1075
1076 "The consensus of researchers in this area (at least as
1077 expressed at the NIST Hash Function Workshop 10/31/05),
1078 is that SHA-256 is a good choice for the time being, but
1079 that research should continue, and other alternatives may
1080 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001081
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001082- Added a subset of Fredrik Lundh's ElementTree package. Available

1157
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00001158- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
1159 to W3C name (404 -> 'Not Found'). RFE #1216944.
1160
Georg Brandl9e43acf2005-07-04 17:16:07 +00001161- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1162 as this can cause problems with apps closing all file descriptors.
1163
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001164- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001165 it can be missing in embedded interpreters
Georg Brandl5284b532005-06-26 22:54:58 +00001166
Georg Brandl2f210b62005-06-26 22:09:06 +00001167- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
1168
Georg Brandlfbff1bc2005-06-26 21:36:25 +00001169- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
1170 error messages.
1171
Georg Brandl379f99d2005-06-26 21:09:38 +00001172- Bug #1108948: Cookie.py produced invalid JavaScript code.
1173
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00001174- The tokenize module now detects and reports indentation errors.
1175 Bug #1224621.
1176
Raymond Hettinger68c04532005-06-10 11:05:19 +00001177- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001178 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001179 the generate_tokens() function now accepts a callable argument that
1180 terminates by raising StopIteration.
1181
Georg Brandl9166e1a2005-06-04 09:20:03 +00001182- Bug #1196315: fix weakref.WeakValueDictionary constructor.
1183
Georg Brandl268e61c2005-06-03 14:28:50 +00001184- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
1185 component of the path.
1186
Skip Montanaro174dd222005-05-14 20:54:16 +00001187- Patch #1120353: The xmlrpclib module provides better, more transparent,
1188 support for datetime.{datetime,date,time} objects. With use_datetime set
1189 to True, applications shouldn't have to fiddle with the DateTime wrapper
1190 class at all.
1191
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001192- distutils.commands.upload was added to support uploading distribution
1193 files to PyPI.
1194
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001195- distutils.commands.register now encodes the data as UTF-8 before posting
1196 them to PyPI.
1197
Raymond Hettinger267b8682005-03-27 10:47:39 +00001198- decimal operator and comparison methods now return NotImplemented
1199 instead of raising a TypeError when interacting with other types. This
1200 allows other classes to implement __radd__ style methods and have them
1201 work as expected.
1202
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001203- Bug #1163325: Decimal infinities failed to hash. Attempting to
1204 hash a NaN raised an InvalidOperation instead of a TypeError.
1205
Tim Petersecc6e6a2005-07-10 22:30:55 +00001206- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001207 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1208
Martin v. Löwis00a73e72005-03-04 19:40:34 +00001209- Patch #1043890: Add extractall method to tarfile.

1240
Guido van Rossumd0641422005-02-03 15:01:24 +00001241- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1242 disables recursive traversal through instance attributes, which can
1243 be exploited in various ways.
1244
Tim Peterse3547fd2005-12-16 23:13:57 +00001245- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001246 flags on the HTTP listening socket.
1247
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001248- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1249 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1250
Tim Peterse3547fd2005-12-16 23:13:57 +00001251- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001252 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1253
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001254- Bug #1110478: Revert os.environ.update to do putenv again.
1255
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001256- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1257
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001258- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1259
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001260- Enhancements to the csv module:
1261
1262 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001263 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001264 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001265 + Dialect parameter parsing has been re-implemented to improve error
1266 reporting.
1267 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1268 dictates.
1269 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001270 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001271 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001272 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1273 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001274 + reader now allows \r characters to be quoted (previously it only allowed
1275 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001276 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001277 + Dialect classes passed to the module are no longer instantiated by
1278 the module before being parsed (the former validation scheme required
1279 this, but the mechanism was unreliable).
1280 + The dialect registry now contains instances of the internal
1281 C-coded dialect type, rather than references to python objects.
1282 + the internal c-coded dialect type is now immutable.
1283 + register_dialect now accepts the same keyword dialect specifications
1284 as the reader and writer, allowing the user to register dialects
1285 without first creating a dialect class.
1286 + a configurable limit to the size of parsed fields has been added -
1287 previously, an unmatched quote character could result in the entire
1288 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001289 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001290 the parser field size limit (returning the former limit). The initial
1291 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001292 + A line_num attribute has been added to the reader object, which tracks
1293 the number of lines read from the source iterator. This is not
1294 the same as the number of records returned, as records can span
1295 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001296 + reader and writer objects were not being registered with the cyclic-GC.
1297 This has been fixed.
1298
Brett Cannone6539c42005-01-08 02:43:53 +00001299- _DummyThread objects in the threading module now delete self.__block that is
1300 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1301 lock primitives tend to be limited in number and thus should not be wasted on
1302 a _DummyThread object. Fixes bug #1089632.
1303
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001304- The imghdr module now detects Exif files.
1305
Raymond Hettinger6065d322004-12-20 23:51:53 +00001306- StringIO.truncate() now correctly adjusts the size attribute.
1307 (Bug #951915).
1308
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001309- locale.py now uses an updated locale alias table (built using
1310 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1311 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001312 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001313
Raymond Hettinger3557f422004-12-07 12:02:02 +00001314- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1315
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001316- the pickle module no longer accepts the deprecated None option in the
1317 args tuple returned by __reduce__().
1318
Brett Cannon84667c02004-12-07 03:25:18 +00001319- optparse now optionally imports gettext. This allows its use in setup.py.
1320
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001321- the pickle module no longer uses the deprecated bin parameter.
1322
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001323- the shelve module no longer uses the deprecated binary parameter.
1324
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001325- the pstats module no longer uses the deprecated ignore() method.
1326
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001327- the filecmp module no longer uses the deprecated use_statcache argument.
1328
Raymond Hettinger664347b2004-12-04 21:21:53 +00001329- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1330 extended or overridden by subclasses. Formerly, the subclassed method would
1331 be ignored by the rest of the module. (Bug #1078905).
1332
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001333- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001334 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001335
Walter Dörwald36733692004-12-22 12:50:50 +00001336- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1337 once when a size argument is given. This prevents a buffer overflow in the
1338 tokenizer with very long source lines.
1339
Barry Warsaw538561e2006-01-01 21:48:54 +00001340- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1341 immediately after creating the object, without any intervening
1342 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001343
Skip Montanaro05885812005-01-16 20:48:27 +00001344- The reconvert.quote function can now emit triple-quoted strings. The
1345 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001346
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001347- ``UserString.MutableString`` now supports negative indices in
1348 ``__setitem__`` and ``__delitem__``
1349
Greg Ward40407942005-03-05 02:53:17 +00001350- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1351 correctly.
1352
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001353- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1354 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1355 character even if the user has passed a size parameter to get a proper
1356 line ending. Remove the special handling of a "\r\n" that has been split
1357 between two lines.
1358
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001359- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1360 about illegal code points. The codec now supports PEP 293 style error
1361 handlers.
1362
Walter Dörwald78a78b02005-09-01 12:04:29 +00001363- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001364 from the input stream, so that the output is a byte string in the correct
1365 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001366
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001367- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1368 considering it exactly like a '*'.
1369
Walter Dörwald007f8df2005-10-09 19:42:27 +00001370- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1371 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001372
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001373- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1374
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001375- Patch #1413711: Certain patterns of differences were making difflib
1376 touch the recursion limit.
1377
Walter Dörwald58917a62006-03-31 15:26:22 +00001378- Bug #947906: An object oriented interface has been added to the calendar
1379 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001380 called as a script (e.g. via ``python -mcalendar``). Localized month and
1381 weekday names can be ouput (even if an exotic encoding is used) using
1382 special classes that use unicode.

1407 vulnerability in zlib 1.2.1 and 1.2.2.
1408
Brett Cannon08cd5982005-04-24 22:26:38 +00001409- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1410 flags that change binary compatibility. Changes were also made to
1411 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001412 compilation of the interpreter and of C extensions through distutils.

Bob Ippolitoed233462005-03-29 13:47:59 +00001414- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1415 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1416 no longer exists). This configure patch makes things right.
1417
Martin v. Löwise2713be2005-03-08 15:03:08 +00001418- Bug #1158607: Build with --disable-unicode again.
1419
Brett Cannon46d96232005-02-16 00:07:19 +00001420- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1421 defined. Discovered as a result of not being able to build on OS X.
1422
Brett Cannon516592f2004-12-07 00:42:59 +00001423- setup.py now uses the directories specified in LDFLAGS using the -L option
1424 and in CPPFLAGS using the -I option for adding library and include
1425 directories, respectively, for compiling extension modules against. This has
1426 led to the core being compiled using the values in CPPFLAGS. It also removes
1427 the need for the special-casing of both DarwinPorts and Fink for darwin since
1428 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1429 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1430 Fink, ``-I/opt/local/include`` for DarwinPorts).
1431
Brett Cannon43802422005-02-10 20:48:03 +00001432- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1433 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1434 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1435 Closes bug #1096244. Thanks Gregory Bond.

1438-----
1439
Tim Petersc9d78aa2006-03-26 23:27:58 +00001440- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1441 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1442 is obtained via the ``PyObject_`` family, it must be released via the
1443 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1444 always been officially true, but when Python's small-object allocator was
1445 introduced, an attempt was made to cater to a few extension modules
1446 discovered at the time that obtained memory via ``PyObject_New`` but
1447 released it via ``PyMem_DEL``. It's years later, and if such code still
1448 exists it will fail now (probably with segfaults, but calling wrong
1449 low-level memory management functions can yield many symptoms).
1450
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001451- Added a C API for set and frozenset objects.
1452
Raymond Hettinger66517482004-12-03 11:45:13 +00001453- Removed PyRange_New().
1454
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001455- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1456 mapping argument now. This string is used as a mapping table. Byte values
1457 greater than the length of the string and 0xFFFE are treated as undefined
1458 mappings.

Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001466- Patch #1276356: New resource "urlfetch" is implemented. This enables
1467 even impatient people to run tests that require remote files.
