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. Smith506f7b52006-06-15 08:52:32 +0000155- bsddb: multithreaded DB access using the simple bsddb module interface
156 now works reliably. It has been updated to use automatic BerkeleyDB
157 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
158 database calls that would previously deadlock. [SF python bug #775414]
159
Ronald Oussoren143cefb2006-06-15 08:14:18 +0000160- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +0000161
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000162
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000163Library
164-------
165
Martin v. Löwis3798da02006-06-17 18:44:27 +0000166- Patch #812986: Update turtle output even if not tracing.
167
Martin v. Löwis92733be2006-06-17 09:25:15 +0000168- Patch #1494750: Destroy master after deleting children in
169 Tkinter.BaseWidget.
170
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000171- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
172
Martin v. Löwis337487e2006-06-17 09:15:14 +0000173- Patch #763580: Add name and value arguments to Tkinter variable
174 classes.
175
Georg Brandl83cc0d02006-06-14 08:50:03 +0000176- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
177 mime.types file for determining MIME types.
178
Georg Brandl2605ca82006-06-14 06:08:31 +0000179- Bug #1339007: Shelf objects now don't raise an exception in their
180 __del__ method when initialization failed.
181
Martin v. Löwisd8251432006-06-14 05:21:04 +0000182- Patch #1455898: The MBCS codec now supports the incremental mode for
183 double-byte encodings.
184
Tim Peters43898b42006-06-14 04:09:25 +0000185- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
186 guarantee that adjacent triples in the return list always describe
187 non-adjacent blocks. Previously, a pair of matching blocks could end
188 up being described by multiple adjacent triples that formed a partition
189 of the matching pair.
190
Greg Ward0e0c9f42006-06-11 16:24:11 +0000191- Bug #1498146: fix optparse to handle Unicode strings in option help,
192 description, and epilog.
193
Greg Wardd1c797e2006-06-11 14:42:41 +0000194- Bug #1366250: minor optparse documentation error.
195
Greg Ward7f547402006-06-11 00:40:49 +0000196- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
197 clarify docs.
198
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000199- The wsgiref package has been added to the standard library.
200
Nick Coghlan676725d2006-06-08 13:54:49 +0000201- The functions update_wrapper() and wraps() have been added to the functools
202 module. These make it easier to copy relevant metadata from the original
203 function when writing wrapper functions.
204
Tim Petersd6a9eef2006-06-05 01:48:21 +0000205- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
206 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000207
Martin v. Löwis3f767792006-06-04 19:36:28 +0000208- Patch #1359618: Speed up charmap encoder by using a trie structure
209 for lookup.
210
Tim Petersd609b1a2006-06-02 23:22:51 +0000211- The functions in the ``pprint`` module now sort dictionaries by key
212 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
213 if and only if its display required more than one line, although that
214 wasn't documented. The new behavior increases predictability; e.g.,
215 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
216
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000217- Patch #1497027: try HTTP digest auth before basic auth in urllib2
218 (thanks for J. J. Lee).
219
Georg Brandl2b330372006-05-28 20:23:12 +0000220- Patch #1496206: improve urllib2 handling of passwords with respect to
221 default HTTP and HTTPS ports.
222
George Yoshidaf3c65de2006-05-28 16:39:09 +0000223- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
224
Bob Ippolito7298f272006-05-23 18:43:47 +0000225- Patch #1281707: speed up gzip.readline.
226
Georg Brandlb89316f2006-05-17 15:51:16 +0000227- Patch #1180296: Two new functions were added to the locale module:
228 format_string() to get the effect of "format % items" but locale-aware,
229 and currency() to format a monetary number with currency sign.
230
Georg Brandle3a25832006-05-17 14:56:04 +0000231- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
232 and several features added, such as speed and geometry control.
233
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000234- Patch #1488881: add support for external file objects in bz2 compressed
235 tarfiles.
236
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000237- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
238 stdout arguments, making it possible to redirect input and output
239 for remote debugging.
240
241- Patch #1484695: Update the tarfile module to version 0.8. This fixes
242 a couple of issues, notably handling of long file names using the
243 GNU LONGNAME extension.
244
245- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
246 new flag when ``name`` is already the name of an option flag.
247
248- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
249 package.
250
251- Patch #1472854: make the rlcompleter.Completer class usable on non-
252 UNIX platforms.
253
254- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
255
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000256- Bug #1472827: correctly escape newlines and tabs in attribute values in
257 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000287What's New in Python 2.5 alpha 2?
288=================================
289
290*Release date: 27-APR-2006*
291
292Core and builtins
293-----------------
294
Thomas Heller1b046642006-04-18 18:51:06 +0000295- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
296 by converting these apis from macros into exported functions again:
297
298 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
299 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
300 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
301 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
302 PyRun_String Py_CompileString
303
Martin v. Löwis45294a92006-04-18 06:24:08 +0000304- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
305
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000306- All uses of PyStructSequence_InitType have been changed to initialize
307 the type objects only once, even if the interpreter is initialized
308 multiple times.
309
Neal Norwitz61546162006-04-14 05:20:28 +0000310- Bug #1454485, array.array('u') could crash the interpreter. This was
311 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
312 to unicode when it didn't make sense. 'u#' now requires a unicode string.
313
314- Py_UNICODE is unsigned. It was always documented as unsigned, but
315 due to a bug had a signed value in previous versions.
316
Tim Peters3a5e8b12006-04-11 01:44:07 +0000317- Patch #837242: ``id()`` of any Python object always gives a positive
318 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
319 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000320 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000321 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000322
Tim Peters3a5e8b12006-04-11 01:44:07 +0000323 def __hash__(self):
324 return id(self) # WRONG
325
326 because a hash result must be a (short) Python int but it was always
327 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000328 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000329 was always usable as a hash value before this patch. That's no longer
330 necessarily so.
331
332- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000333 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000334 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000335 #1454844)
336
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000337- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
338 involving generators that have paused outside of any ``try`` or ``with``
339 blocks. (In 2.5a1, a paused generator that was part of a reference
340 cycle could not be garbage collected, regardless of whether it was
341 paused in a ``try`` or ``with`` block.)

350 fails with an error condition.
351
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000352- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
353
354- Bug #1117761: bsddb.*open() no longer raises an exception when using
355 the cachesize parameter.
356
357- Bug #1149413: bsddb.*open() no longer raises an exception when using
358 a temporary db (file=None) with the 'n' flag to truncate on open.
359
360- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
361 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000362
Armin Rigoa9017c32006-04-19 11:50:27 +0000363- Patch #1062014: AF_UNIX sockets under Linux have a special
364 abstract namespace that is now fully supported.
365
Anthony Baxter51bcb682006-04-05 14:51:42 +0000366Library
367-------
368
Tim Peters711bf302006-04-25 03:31:36 +0000369- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
370 a doctest to be skipped (the code is not run, and the expected output
371 or exception is ignored).
372
Nick Coghlanda2268f2006-04-24 04:37:15 +0000373- Fixed contextlib.nested to cope with exceptions being raised and
374 caught inside exit handlers.
375
Greg Wardab05edc2006-04-23 03:47:58 +0000376- Updated optparse module to Optik 1.5.1 (allow numeric constants in
377 hex, octal, or binary; add ``append_const`` action; keep going if
378 gettext cannot be imported; added ``OptionParser.destroy()`` method;
379 added ``epilog`` for better help generation).
380
Tim Peters21fbd572006-04-21 21:18:10 +0000381- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
382 called from a thread spawned as a side effect of importing a module.
383
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000384- The pydoc module now supports documenting packages contained in
385 .zip or .egg files.
386
387- The pkgutil module now has several new utility functions, such
388 as ``walk_packages()`` to support working with packages that are either
389 in the filesystem or zip files.
390
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000391- The mailbox module can now modify and delete messages from
392 mailboxes, in addition to simply reading them. Thanks to Gregory
393 K. Johnson for writing the code, and to the 2005 Google Summer of
394 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000395
Tim Petersc7605f22006-04-17 21:12:33 +0000396- The ``__del__`` method of class ``local`` in module ``_threading_local``
397 returned before accomplishing any of its intended cleanup.
398

Anthony Baxtere29002c2006-04-12 12:07:31 +0000405- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
406 Windows. Bug #1469163.
407
Phillip J. Eby47032112006-04-11 01:07:43 +0000408- The warnings, linecache, inspect, traceback, site, and doctest modules
409 were updated to work correctly with modules imported from zipfiles or
410 via other PEP 302 __loader__ objects.
411
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000412- Patch #1467770: Reduce usage of subprocess._active to processes which
413 the application hasn't waited on.
414

418
Skip Montanaro262fb922006-04-21 02:31:07 +0000419- The pstats.Stats class accepts an optional stream keyword argument to
420 direct output to an alternate file-like object.
421
Anthony Baxter51bcb682006-04-05 14:51:42 +0000422Build
423-----
424
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000425- The Makefile now has a reindent target, which runs reindent.py on
426 the library.
427
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000428- Patch #1470875: Building Python with MS Free Compiler
429
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000430- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000431
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000432- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
433 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000434 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000435 CXX from --with-cxx-main, see description in README.
436
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000437- Patch #1429775: Link extension modules with the shared libpython.
438
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000439- Fixed a libffi build problem on MIPS systems.
440
Tim Peters8931ff12006-05-13 23:28:20 +0000441- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
442 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
443 and "%zu" for unsigned integers of type ``size_t``.
444
Anthony Baxter51bcb682006-04-05 14:51:42 +0000445Tests
446-----
447
Nick Coghlanda2268f2006-04-24 04:37:15 +0000448- test_contextlib now checks contextlib.nested can cope with exceptions
449 being raised and caught inside exit handlers.
450
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000451- test_cmd_line now checks operation of the -m and -c command switches
452
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000453- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
454 it separately and by hand. It also wasn't cleaning up its changes to
455 the current Decimal context.
456
Thomas Woutersabd08882006-04-26 15:53:30 +0000457- regrtest.py now has a -M option to run tests that test the new limits of
458 containers, on 64-bit architectures. Running these tests is only sensible
459 on 64-bit machines with more than two gigabytes of memory. The argument
460 passed is the maximum amount of memory for the tests to use.

469-------------
470
Tim Petersb06d28c2006-05-12 01:57:59 +0000471- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
472
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000473- PEP 343: Added Context Types section to the library reference
474 and attempted to bring other PEP 343 related documentation into
475 line with the implementation and/or python-dev discussions.
476
Tim Peters8dc73d22006-04-24 02:03:16 +0000477- Bug #1337990: clarified that ``doctest`` does not support examples
478 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000481What's New in Python 2.5 alpha 1?
482=================================
483
Anthony Baxterebed3f62006-04-03 15:03:44 +0000484*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000485
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000486Core and builtins
487-----------------
488
Nick Coghlan43832302006-04-23 17:04:07 +0000489- PEP 338: -m command line switch now delegates to runpy.run_module
490 allowing it to support modules in packages and zipfiles
491
Martin v. Löwisc661b882006-04-20 04:54:23 +0000492- On Windows, .DLL is not an accepted file name extension for
493 extension modules anymore; extensions are only found if they
494 end in .PYD.
495
Martin v. Löwisea62d252006-04-03 10:56:49 +0000496- Bug #1421664: sys.stderr.encoding is now set to the same value as
497 sys.stdout.encoding.
498
Neal Norwitz92e212f2006-04-03 04:48:37 +0000499- __import__ accepts keyword arguments.
500
Georg Brandlccadf842006-03-31 18:54:53 +0000501- Patch #1460496: round() now accepts keyword arguments.
502
Anthony Baxter262c00a2006-03-30 10:53:17 +0000503- Fixed bug #1459029 - unicode reprs were double-escaped.
504
Hye-Shik Changd478f342006-03-23 12:32:36 +0000505- Patch #1396919: The system scope threads are reenabled on FreeBSD
506 5.4 and later versions.
507
Neal Norwitze98ccf62006-03-23 05:39:47 +0000508- Bug #1115379: Compiling a Unicode string with an encoding declaration
509 now gives a SyntaxError.
510
Georg Brandlabd1ff82006-03-18 07:59:59 +0000511- Previously, Python code had no easy way to access the contents of a
512 cell object. Now, a ``cell_contents`` attribute has been added
513 (closes patch #1170323).
514
Tim Peterscf79aac2006-03-16 01:14:46 +0000515- Patch #1123430: Python's small-object allocator now returns an arena to
516 the system ``free()`` when all memory within an arena becomes unused
517 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
518 freed. Some applications will see a drop in virtual memory size now,
519 especially long-running applications that, from time to time, temporarily
520 use a large number of small objects. Note that when Python returns an
521 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000522 platform C library will in turn return that memory to the operating system.
523 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000524 appears to be effective at least on Microsoft C and gcc-based systems.
525 Thanks to Evan Jones for hard work and patience.
526
Georg Brandl533ff6f2006-03-08 18:09:27 +0000527- Patch #1434038: property() now uses the getter's docstring if there is
528 no "doc" argument given. This makes it possible to legitimately use
529 property() as a decorator to produce a read-only property.
530
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000531- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
532 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
533 of requiring an int or long in slicing and a few other contexts, enabling
534 other objects (e.g. Numeric Python's integers) to be used as slice indices.
535
Neal Norwitz995acdf2006-03-07 05:01:00 +0000536- Fixed various bugs reported by Coverity's Prevent tool.
537
Brett Cannonbf364092006-03-01 04:25:17 +0000538- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
539 new exception base class, BaseException, which has a new message attribute.
540 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
541 Raising a string exception now raises a DeprecationWarning.
542
Thomas Woutersfb609f42006-02-28 16:37:25 +0000543- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
544 explicitly relative, using 'from .module import name' to mean 'from the same
545 package as this module is in. Imports without dots still default to the
546 old relative-then-absolute, unless 'from __future__ import
547 absolute_import' is used.
548
Brett Cannona7446e32006-02-27 23:39:10 +0000549- Properly check if 'warnings' raises an exception (usually when a filter set
550 to "error" is triggered) when raising a warning for raising string
551 exceptions.
552
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000553- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000554 The name was removed from Include/code.h.
555
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000556- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000557
Guido van Rossum1968ad32006-02-25 22:38:04 +0000558- Patch 1433928:
559 - The copy module now "copies" function objects (as atomic objects).
560 - dict.__getitem__ now looks for a __missing__ hook before raising
561 KeyError.
562
Tim Peters84ef21c2006-02-28 20:39:06 +0000563- PEP 343: with statement implemented. Needs ``from __future__ import
564 with_statement``. Use of 'with' as a variable will generate a warning.
565 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000566 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000567 The following objects have __context__ methods:
568 - The built-in file type.
569 - The thread.LockType type.
570 - The following types defined by the threading module:
571 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
572 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000573
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000574- Fix the encodings package codec search function to only search
575 inside its own package. Fixes problem reported in patch #1433198.
576
577 Note: Codec packages should implement and register their own
578 codec search function. PEP 100 has the details.
579
Tim Peters9ea89d22006-06-04 03:26:02 +0000580- PEP 353: Using ``Py_ssize_t`` as the index type.
581
582- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
583 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
584 now allow Python to make use of memory blocks exceeding 2**32 bytes for
585 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
586 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000587
Neal Norwitzfc76d632006-01-10 06:03:13 +0000588- Patch #1400181, fix unicode string formatting to not use the locale.
589 This is how string objects work. u'%f' could use , instead of .
590 for the decimal point. Now both strings and unicode always use periods.
591
Neal Norwitz671b9e32006-01-09 07:07:12 +0000592- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
593 configure would break checking curses.h.
594
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000595- Bug #959576: The pwd module is now builtin. This allows Python to be
596 built on UNIX platforms without $HOME set.
597
Neal Norwitzc10978f2005-12-19 06:07:16 +0000598- Bug #1072182, fix some potential problems if characters are signed.
599
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000600- Bug #889500, fix line number on SyntaxWarning for global declarations.
601
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000602- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
603
Neal Norwitze7214a12005-12-18 05:03:17 +0000604- Support for converting hex strings to floats no longer works.
605 This was not portable. float('0x3') now raises a ValueError.
606
Barry Warsaw2a38a862005-12-18 01:27:35 +0000607- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000608 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000609 is now displayed in interactive prompt banner.
610
Georg Brandlfa166682005-12-17 21:45:17 +0000611- Implementation of PEP 341 - Unification of try/except and try/finally.
612 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000613 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000614
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000615- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
616 now encodes backslash correctly.
617
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000618- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
619
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000620- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs

Neal Norwitz67715f02005-11-09 06:59:35 +0000623- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000624 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000625 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000626
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000627- Replaced most Unicode charmap codecs with new ones using the
628 new Unicode translate string feature in the builtin charmap
629 codec; the codecs were created from the mapping tables available
630 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
631 encodings now include a mapping for the Apple logo)
632
Tim Peterse3547fd2005-12-16 23:13:57 +0000633- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000634
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000635- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000636
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000637- A new AST parser implementation was completed. The abstract
638 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000639 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000640
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000641- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000642 The following code now raises a SyntaxError: foo(a = i for i in range(10))
643
Neal Norwitz708e51a2005-10-03 04:48:15 +0000644- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
645
Neal Norwitz11bd1192005-10-03 00:54:56 +0000646- SF Bug #887946: fix segfault when redirecting stdin from a directory.
647 Provide a warning when a directory is passed on the command line.
648
Neal Norwitz40d37812005-10-02 01:48:49 +0000649- Fix segfault with invalid coding.
650
651- SF bug #772896: unknown encoding results in MemoryError.
652
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000653- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000654 supported a __len__() method which evaluated to False when the iterator
655 was empty.
656
Guido van Rossum630db602005-09-20 18:49:54 +0000657- On 64-bit platforms, when __len__() returns a value that cannot be
658 represented as a C int, raise OverflowError.
659
Skip Montanarof8948ca2005-09-19 03:54:46 +0000660- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000661 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000662
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000663- SF bug #893549: parsing keyword arguments was broken with a few format
664 codes.
665
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000666- Changes donated by Elemental Security to make it work on AIX 5.3
667 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
668 bug #105470: test_pwd fails on 64bit system (Opteron).
669
Guido van Rossum539c6622005-09-14 17:49:54 +0000670- Changes donated by Elemental Security to make it work on HP-UX 11 on
671 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
672
Georg Brandl4550b8d2005-08-26 06:43:52 +0000673- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000674 (fixes bug #1119418).
675
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000676- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
677
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000678- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
679 exceptions that cause a function to exit.
680
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000681- The implementation of set() and frozenset() was revised to use its
682 own internal data structure. Memory consumption is reduced by 1/3
683 and there are modest speed-ups as well. The API is unchanged.
684
Tim Petersde7990b2005-07-17 23:45:23 +0000685- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
686
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000687- SF bug #1229429: PyObject_CallMethod failed to decrement some
688 reference counts in some error exit cases.
689
Tim Petersecc6e6a2005-07-10 22:30:55 +0000690- SF bug #1185883: Python's small-object memory allocator took over
691 a block managed by the platform C library whenever a realloc specified
692 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000693 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000694 portable way to copy data from the C-managed block into Python's
695 small-object space without risking a memory fault. Python's small-object
696 realloc now leaves such blocks under the control of the platform C
697 realloc.
698
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000699- SF bug #1232517: An overflow error was not detected properly when
700 attempting to convert a large float to an int in os.utime().
701
Raymond Hettinger3296e692005-06-29 23:29:56 +0000702- SF bug #1224347: hex longs now print with lowercase letters just
703 like their int counterparts.
704
Michael W. Hudson188d4362005-06-20 16:52:57 +0000705- SF bug #1163563: the original fix for bug #1010677 ("thread Module
706 Breaks PyGILState_Ensure()") broke badly in the case of multiple
707 interpreter states; back out that fix and do a better job (see
708 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
709 for a longer write-up of the problem).
710
Michael W. Hudsondf888462005-06-03 14:41:55 +0000711- SF patch #1180995: marshal now uses a binary format by default when
712 serializing floats.
713
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000714- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
715 the routines that promise to produce IEEE 754 binary representations
716 of floats now simply copy bytes around.
717
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000718- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
719 278.
720
Brett Cannonc3647ac2005-04-26 03:45:26 +0000721- patch #1109424: int, long, float, complex, and unicode now check for the
722 proper magic slot for type conversions when subclassed. Previously the
723 magic slot was ignored during conversion. Semantics now match the way
724 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000725 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000726 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000727 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000728
Barry Warsawc8d907c2005-04-19 23:43:40 +0000729- Descriptors defined in C with a PyGetSetDef structure, where the setter is
730 NULL, now raise an AttributeError when attempting to set or delete the
731 attribute. Previously a TypeError was raised, but this was inconsistent
732 with the equivalent pure-Python implementation.
733
Michael W. Hudson774479c2005-04-18 08:46:17 +0000734- It is now safe to call PyGILState_Release() before
735 PyEval_InitThreads() (note that if there is reason to believe there
736 are multiple threads around you still must call PyEval_InitThreads()
737 before using the Python API; this fix is for extension modules that
738 have no way of knowing if Python is multi-threaded yet).
739
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000740- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
741 disabled caused a crash.
742
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000743- Bug #1165306: instancemethod_new allowed the creation of a method
744 with im_class == im_self == NULL, which caused a crash when called.
745
Tim Petersecc6e6a2005-07-10 22:30:55 +0000746- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000747 fixes the crash seen in bug #1165761
748
Raymond Hettinger96229b12005-03-11 06:49:40 +0000749- Added two new builtins, any() and all().
750
Brett Cannon409d8f22005-03-05 06:47:57 +0000751- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000752 (e.g., ``class C(): pass`` is no longer a syntax error).
753 Patch #1176012 added support to the 'parser' module and 'compiler' package
754 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000755
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000756- Patch #1115086: Support PY_LONGLONG in structmember.
757
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000758- Bug #1155938: new style classes did not check that __init__() was
759 returning None.
760
Tim Petersecc6e6a2005-07-10 22:30:55 +0000761- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000762 ('\') with a specific error message.
763
Martin v. Löwisff232d72005-03-03 09:24:38 +0000764- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
765
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000766- Bug #1124295: the __name__ attribute of file objects was
767 inadvertently made inaccessible in restricted mode.
768
Tim Petersecc6e6a2005-07-10 22:30:55 +0000769- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000770 an ferror() call.
771
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000772- min() and max() now support key= arguments with the same meaning as in
773 list.sort().
774
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000775- The peephole optimizer now performs simple constant folding in expressions:
776 (2+3) --> (5).
777
Raymond Hettingera422c342005-01-11 03:03:27 +0000778- set and frozenset objects can now be marshalled. SF #1098985.
779
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000780- Bug #1077106: Poor argument checking could cause memory corruption
781 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000782
Jeremy Hyltonab630502005-02-04 18:44:06 +0000783- The parser did not complain about future statements in illegal
784 positions. It once again reports a syntax error if a future
785 statement occurs after anything other than a doc string.
786
Neil Schemenauercf52c072005-08-12 17:34:58 +0000787- Change the %s format specifier for str objects so that it returns a
788 unicode instance if the argument is not an instance of basestring and
789 calling __str__ on the argument returns a unicode instance.
790
Tim Petersf4e69282006-02-27 17:15:31 +0000791- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
792 current thread state when the auto-GIL-state machinery knows about
793 it (since the thread state is being deleted, continuing to remember it
794 can't help, but can hurt if another thread happens to get created with
795 the same thread id).
796
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000797Extension Modules
798-----------------
799
Georg Brandl43f08a82006-03-31 18:01:16 +0000800- Patch #1380952: fix SSL objects timing out on consecutive read()s

814
815- The following modules were removed: regsub, reconvert, regex, regex_syntax.
816
817- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +0000818 is deprecated. The undocumented re.engine variable no longer exists.
819
Hye-Shik Changabb903f2006-03-13 10:20:08 +0000820- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
821 SS2 (single-shift 2) escape sequences correctly.
822
Martin v. Löwis480f1bb2006-03-09 23:38:20 +0000823- The unicodedata module was updated to the 4.1 version of the Unicode
824 database. The 3.2 version is still available as unicodedata.db_3_2_0
825 for applications that require this specific version (such as IDNA).
826
Neal Norwitzb62c4332006-03-04 18:35:47 +0000827- The timing module is no longer built by default. It was deprecated
828 in PEP 4 in Python 2.0 or earlier.
829
Guido van Rossum1968ad32006-02-25 22:38:04 +0000830- Patch 1433928: Added a new type, defaultdict, to the collections module.
831 This uses the new __missing__ hook behavior added to dict (see above).
832
Georg Brandldbd83392006-02-20 09:42:33 +0000833- Bug #854823: socketmodule now builds on Sun platforms even when
834 INET_ADDRSTRLEN is not defined.
835
Georg Brandlf4f44152006-02-18 22:29:33 +0000836- Patch #1393157: os.startfile() now has an optional argument to specify
837 a "command verb" to invoke on the file.
838
Neal Norwitz082b2df2006-02-07 07:04:46 +0000839- Bug #876637, prevent stack corruption when socket descriptor
840 is larger than FD_SETSIZE.
841
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +0000842- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
843 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
844 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
845
Martin v. Löwis57a34e82006-02-04 19:12:37 +0000846- Patch #1422385: The nis module now supports access to domains other
847 than the system default domain.
848
Martin v. Löwis14694662006-02-03 12:54:16 +0000849- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
850 are reported, the limit on path name lengths is removed, and stat reports
851 WindowsError now (instead of OSError).
852
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +0000853- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

Michael W. Hudson8137bea2005-07-27 20:24:40 +0000927- Patch #1231069: The fcntl.ioctl function now uses the 'I' code for
928 the request code argument, which results in more C-like behaviour
929 for large or negative values.
930
Tim Petersecc6e6a2005-07-10 22:30:55 +0000931- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

983
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000984Library
985-------
986
Nick Coghlan43832302006-04-23 17:04:07 +0000987- PEP 338: new module runpy defines a run_module function to support
988 executing modules which provide access to source code or a code object
989 via the PEP 302 import mechanisms.
990
Anthony Baxter93f5b932006-04-03 08:05:07 +0000991- The email module's parsedate_tz function now sets the daylight savings

999 in attribute values.
1000
Anthony Baxterc51ee692006-04-01 00:57:31 +00001001- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001002 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001003 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001004 module will not be built.
1005
Tim Petersc17976e2006-04-01 00:26:53 +00001006- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1007 aren't officially supported here, and trying to use them will probably
1008 raise an exception some day. But dicts have been allowed, and "mostly
1009 worked", so support for them won't go away without warning.
1010
Georg Brandl338ef7d2006-03-31 18:42:16 +00001011- Bug #1445068: getpass.getpass() can now be given an explicit stream
1012 argument to specify where to write the prompt.
1013
Georg Brandl22ec80b2006-03-31 18:25:44 +00001014- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1021
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00001022- Queue.Queue objects now support .task_done() and .join() methods
1023 to make it easier to monitor when daemon threads have completed
1024 processing all enqueued tasks. Patch #1455676.
1025
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001026- popen2.Popen objects now preserve the command in a .cmd attribute.

1029
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001030- email 4.0 package now integrated. This is largely the same as the email 3.0
1031 package that was included in Python 2.3, except that PEP 8 module names are
1032 now used (e.g. mail.message instead of email.Message). The MIME classes
1033 have been moved to a subpackage (e.g. email.mime.text instead of
1034 email.MIMEText). The old names are still supported for now. Several
1035 deprecated Message methods have been removed and lots of bugs have been
1036 fixed. More details can be found in the email package documentation.
1037
Walter Dörwald40108c92006-03-27 08:15:44 +00001038- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1039 (a subclass of tuple) that provides incremental decoders and encoders
1040 (a way to use stateful codecs without the stream API). Python functions
1041 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1042 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1043 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001044
Walter Dörwald067db482006-03-15 22:17:27 +00001045- Patch #1359365: Calling next() on a closed StringIO.String object raises
1046 a ValueError instead of a StopIteration now (like file and cString.String do).
1047 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1048 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001049
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001050- A regrtest option -w was added to re-run failed tests in verbose mode.

1062 and helpful context managers nested() and closing().
1063
Martin v. Löwis415ed932006-02-27 19:56:30 +00001064- The compiler package now supports future imports after the module docstring.
1065

Martin v. Löwis3e865952006-01-24 15:51:21 +00001098 specifications, raises IOErrors when proxies for unsupported protocols
1099 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00001122 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1123 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1124 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1125 Ronald L. Rivest offered this advice for Python:
1126
1127 "The consensus of researchers in this area (at least as
1128 expressed at the NIST Hash Function Workshop 10/31/05),
1129 is that SHA-256 is a good choice for the time being, but
1130 that research should continue, and other alternatives may
1131 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001132
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001133- Added a subset of Fredrik Lundh's ElementTree package. Available

1211
Georg Brandl9e43acf2005-07-04 17:16:07 +00001212- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1213 as this can cause problems with apps closing all file descriptors.

1226 Bug #1224621.
1227
Raymond Hettinger68c04532005-06-10 11:05:19 +00001228- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001229 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001230 the generate_tokens() function now accepts a callable argument that
1231 terminates by raising StopIteration.
1232
Georg Brandl9166e1a2005-06-04 09:20:03 +00001233- Bug #1196315: fix weakref.WeakValueDictionary constructor.

1241 class at all.
1242
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001243- distutils.commands.upload was added to support uploading distribution
1244 files to PyPI.
1245
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001246- distutils.commands.register now encodes the data as UTF-8 before posting
1247 them to PyPI.
1248
Raymond Hettinger267b8682005-03-27 10:47:39 +00001249- decimal operator and comparison methods now return NotImplemented
1250 instead of raising a TypeError when interacting with other types. This
1251 allows other classes to implement __radd__ style methods and have them
1252 work as expected.
1253
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001254- Bug #1163325: Decimal infinities failed to hash. Attempting to
1255 hash a NaN raised an InvalidOperation instead of a TypeError.
1256
Tim Petersecc6e6a2005-07-10 22:30:55 +00001257- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001258 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1259

1291
Guido van Rossumd0641422005-02-03 15:01:24 +00001292- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1293 disables recursive traversal through instance attributes, which can
1294 be exploited in various ways.
1295
Tim Peterse3547fd2005-12-16 23:13:57 +00001296- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001297 flags on the HTTP listening socket.
1298
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001299- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1300 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1301
Tim Peterse3547fd2005-12-16 23:13:57 +00001302- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001303 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1304
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001305- Bug #1110478: Revert os.environ.update to do putenv again.
1306
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001307- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1308
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001309- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1310
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001311- Enhancements to the csv module:
1312
1313 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001314 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001315 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001316 + Dialect parameter parsing has been re-implemented to improve error
1317 reporting.
1318 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1319 dictates.
1320 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001321 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001322 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001323 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1324 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001325 + reader now allows \r characters to be quoted (previously it only allowed
1326 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001327 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001328 + Dialect classes passed to the module are no longer instantiated by
1329 the module before being parsed (the former validation scheme required
1330 this, but the mechanism was unreliable).
1331 + The dialect registry now contains instances of the internal
1332 C-coded dialect type, rather than references to python objects.
1333 + the internal c-coded dialect type is now immutable.
1334 + register_dialect now accepts the same keyword dialect specifications
1335 as the reader and writer, allowing the user to register dialects
1336 without first creating a dialect class.
1337 + a configurable limit to the size of parsed fields has been added -
1338 previously, an unmatched quote character could result in the entire
1339 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001340 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001341 the parser field size limit (returning the former limit). The initial
1342 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001343 + A line_num attribute has been added to the reader object, which tracks
1344 the number of lines read from the source iterator. This is not
1345 the same as the number of records returned, as records can span
1346 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001347 + reader and writer objects were not being registered with the cyclic-GC.
1348 This has been fixed.
1349
Brett Cannone6539c42005-01-08 02:43:53 +00001350- _DummyThread objects in the threading module now delete self.__block that is
1351 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1352 lock primitives tend to be limited in number and thus should not be wasted on
1353 a _DummyThread object. Fixes bug #1089632.
1354
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001355- The imghdr module now detects Exif files.
1356
Raymond Hettinger6065d322004-12-20 23:51:53 +00001357- StringIO.truncate() now correctly adjusts the size attribute.
1358 (Bug #951915).
1359
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001360- locale.py now uses an updated locale alias table (built using
1361 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1362 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001363 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001364
Raymond Hettinger3557f422004-12-07 12:02:02 +00001365- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1366
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001367- the pickle module no longer accepts the deprecated None option in the
1368 args tuple returned by __reduce__().
1369
Brett Cannon84667c02004-12-07 03:25:18 +00001370- optparse now optionally imports gettext. This allows its use in setup.py.
1371
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001372- the pickle module no longer uses the deprecated bin parameter.
1373
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001374- the shelve module no longer uses the deprecated binary parameter.
1375
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001376- the pstats module no longer uses the deprecated ignore() method.
1377
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001378- the filecmp module no longer uses the deprecated use_statcache argument.
1379
Raymond Hettinger664347b2004-12-04 21:21:53 +00001380- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1381 extended or overridden by subclasses. Formerly, the subclassed method would
1382 be ignored by the rest of the module. (Bug #1078905).
1383
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001384- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001385 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001386
Walter Dörwald36733692004-12-22 12:50:50 +00001387- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1388 once when a size argument is given. This prevents a buffer overflow in the
1389 tokenizer with very long source lines.
1390
Barry Warsaw538561e2006-01-01 21:48:54 +00001391- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1392 immediately after creating the object, without any intervening
1393 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001394
Skip Montanaro05885812005-01-16 20:48:27 +00001395- The reconvert.quote function can now emit triple-quoted strings. The
1396 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001397
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001398- ``UserString.MutableString`` now supports negative indices in
1399 ``__setitem__`` and ``__delitem__``
1400
Greg Ward40407942005-03-05 02:53:17 +00001401- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1402 correctly.
1403
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001404- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1405 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1406 character even if the user has passed a size parameter to get a proper
1407 line ending. Remove the special handling of a "\r\n" that has been split
1408 between two lines.
1409
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001410- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1411 about illegal code points. The codec now supports PEP 293 style error
1412 handlers.
1413
Walter Dörwald78a78b02005-09-01 12:04:29 +00001414- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001415 from the input stream, so that the output is a byte string in the correct
1416 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001417
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001418- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1419 considering it exactly like a '*'.

Walter Dörwald007f8df2005-10-09 19:42:27 +00001421- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1422 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001423
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001424- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1425
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001426- Patch #1413711: Certain patterns of differences were making difflib
1427 touch the recursion limit.
1428
Walter Dörwald58917a62006-03-31 15:26:22 +00001429- Bug #947906: An object oriented interface has been added to the calendar
1430 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001431 called as a script (e.g. via ``python -mcalendar``). Localized month and
1432 weekday names can be ouput (even if an exotic encoding is used) using
1433 special classes that use unicode.

1437
Neal Norwitz602d3392006-03-31 08:21:40 +00001438- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1439 by using -mieee gcc option.
1440

1442
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001443- Build support for Win64-AMD64 was added.
1444
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001445- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1446
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001447- Patch #881820: look for openpty and forkpty also in libbsd.
1448
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001449- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1450 The zlib module is now builtin on Windows.
1451
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001452- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1453
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001454- Bug #1189330: configure did not correctly determine the necessary
1455 value of LINKCC if python was built with GCC 4.0.
1456
Trent Mick8321b422005-07-26 02:29:21 +00001457- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1458 vulnerability in zlib 1.2.1 and 1.2.2.
1459
Brett Cannon08cd5982005-04-24 22:26:38 +00001460- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1461 flags that change binary compatibility. Changes were also made to
1462 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001463 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001464
Bob Ippolitoed233462005-03-29 13:47:59 +00001465- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1466 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1467 no longer exists). This configure patch makes things right.
1468
Martin v. Löwise2713be2005-03-08 15:03:08 +00001469- Bug #1158607: Build with --disable-unicode again.
1470
Brett Cannon46d96232005-02-16 00:07:19 +00001471- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1472 defined. Discovered as a result of not being able to build on OS X.
1473
Brett Cannon516592f2004-12-07 00:42:59 +00001474- setup.py now uses the directories specified in LDFLAGS using the -L option
1475 and in CPPFLAGS using the -I option for adding library and include
1476 directories, respectively, for compiling extension modules against. This has
1477 led to the core being compiled using the values in CPPFLAGS. It also removes
1478 the need for the special-casing of both DarwinPorts and Fink for darwin since
1479 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1480 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1481 Fink, ``-I/opt/local/include`` for DarwinPorts).
1482
Brett Cannon43802422005-02-10 20:48:03 +00001483- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1484 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1485 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1486 Closes bug #1096244. Thanks Gregory Bond.

1489-----
1490
Tim Petersc9d78aa2006-03-26 23:27:58 +00001491- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1492 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1493 is obtained via the ``PyObject_`` family, it must be released via the
1494 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1495 always been officially true, but when Python's small-object allocator was
1496 introduced, an attempt was made to cater to a few extension modules
1497 discovered at the time that obtained memory via ``PyObject_New`` but
1498 released it via ``PyMem_DEL``. It's years later, and if such code still
1499 exists it will fail now (probably with segfaults, but calling wrong
1500 low-level memory management functions can yield many symptoms).
1501
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001502- Added a C API for set and frozenset objects.
1503
Raymond Hettinger66517482004-12-03 11:45:13 +00001504- Removed PyRange_New().
1505
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001506- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1507 mapping argument now. This string is used as a mapping table. Byte values
1508 greater than the length of the string and 0xFFFE are treated as undefined
1509 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00001515- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001516
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001517- Patch #1276356: New resource "urlfetch" is implemented. This enables
1518 even impatient people to run tests that require remote files.
