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. Löwis6fb20aa2006-06-17 19:03:26 +0000166- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
167 functions.
168
Martin v. Löwis3798da02006-06-17 18:44:27 +0000169- Patch #812986: Update turtle output even if not tracing.
170
Martin v. Löwis92733be2006-06-17 09:25:15 +0000171- Patch #1494750: Destroy master after deleting children in
172 Tkinter.BaseWidget.
173
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000174- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
175
Martin v. Löwis337487e2006-06-17 09:15:14 +0000176- Patch #763580: Add name and value arguments to Tkinter variable
177 classes.
178
Georg Brandl83cc0d02006-06-14 08:50:03 +0000179- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
180 mime.types file for determining MIME types.
181
Georg Brandl2605ca82006-06-14 06:08:31 +0000182- Bug #1339007: Shelf objects now don't raise an exception in their
183 __del__ method when initialization failed.
184
Martin v. Löwisd8251432006-06-14 05:21:04 +0000185- Patch #1455898: The MBCS codec now supports the incremental mode for
186 double-byte encodings.
187
Tim Peters43898b42006-06-14 04:09:25 +0000188- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
189 guarantee that adjacent triples in the return list always describe
190 non-adjacent blocks. Previously, a pair of matching blocks could end
191 up being described by multiple adjacent triples that formed a partition
192 of the matching pair.
193
Greg Ward0e0c9f42006-06-11 16:24:11 +0000194- Bug #1498146: fix optparse to handle Unicode strings in option help,
195 description, and epilog.
196
Greg Wardd1c797e2006-06-11 14:42:41 +0000197- Bug #1366250: minor optparse documentation error.
198
Greg Ward7f547402006-06-11 00:40:49 +0000199- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
200 clarify docs.
201
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000202- The wsgiref package has been added to the standard library.
203
Nick Coghlan676725d2006-06-08 13:54:49 +0000204- The functions update_wrapper() and wraps() have been added to the functools
205 module. These make it easier to copy relevant metadata from the original
206 function when writing wrapper functions.
207
Tim Petersd6a9eef2006-06-05 01:48:21 +0000208- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
209 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000210
Martin v. Löwis3f767792006-06-04 19:36:28 +0000211- Patch #1359618: Speed up charmap encoder by using a trie structure
212 for lookup.
213
Tim Petersd609b1a2006-06-02 23:22:51 +0000214- The functions in the ``pprint`` module now sort dictionaries by key
215 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
216 if and only if its display required more than one line, although that
217 wasn't documented. The new behavior increases predictability; e.g.,
218 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
219
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000220- Patch #1497027: try HTTP digest auth before basic auth in urllib2
221 (thanks for J. J. Lee).
222
Georg Brandl2b330372006-05-28 20:23:12 +0000223- Patch #1496206: improve urllib2 handling of passwords with respect to
224 default HTTP and HTTPS ports.
225
George Yoshidaf3c65de2006-05-28 16:39:09 +0000226- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
227
Bob Ippolito7298f272006-05-23 18:43:47 +0000228- Patch #1281707: speed up gzip.readline.
229
Georg Brandlb89316f2006-05-17 15:51:16 +0000230- Patch #1180296: Two new functions were added to the locale module:
231 format_string() to get the effect of "format % items" but locale-aware,
232 and currency() to format a monetary number with currency sign.
233
Georg Brandle3a25832006-05-17 14:56:04 +0000234- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
235 and several features added, such as speed and geometry control.
236
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000237- Patch #1488881: add support for external file objects in bz2 compressed
238 tarfiles.
239
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000240- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
241 stdout arguments, making it possible to redirect input and output
242 for remote debugging.
243
244- Patch #1484695: Update the tarfile module to version 0.8. This fixes
245 a couple of issues, notably handling of long file names using the
246 GNU LONGNAME extension.
247
248- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
249 new flag when ``name`` is already the name of an option flag.
250
251- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
252 package.
253
254- Patch #1472854: make the rlcompleter.Completer class usable on non-
255 UNIX platforms.
256
257- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
258
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000259- Bug #1472827: correctly escape newlines and tabs in attribute values in
260 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000290What's New in Python 2.5 alpha 2?
291=================================
292
293*Release date: 27-APR-2006*
294
295Core and builtins
296-----------------
297
Thomas Heller1b046642006-04-18 18:51:06 +0000298- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
299 by converting these apis from macros into exported functions again:
300
301 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
302 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
303 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
304 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
305 PyRun_String Py_CompileString
306
Martin v. Löwis45294a92006-04-18 06:24:08 +0000307- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
308
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000309- All uses of PyStructSequence_InitType have been changed to initialize
310 the type objects only once, even if the interpreter is initialized
311 multiple times.
312
Neal Norwitz61546162006-04-14 05:20:28 +0000313- Bug #1454485, array.array('u') could crash the interpreter. This was
314 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
315 to unicode when it didn't make sense. 'u#' now requires a unicode string.
316
317- Py_UNICODE is unsigned. It was always documented as unsigned, but
318 due to a bug had a signed value in previous versions.
319
Tim Peters3a5e8b12006-04-11 01:44:07 +0000320- Patch #837242: ``id()`` of any Python object always gives a positive
321 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
322 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000323 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000324 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000325
Tim Peters3a5e8b12006-04-11 01:44:07 +0000326 def __hash__(self):
327 return id(self) # WRONG
328
329 because a hash result must be a (short) Python int but it was always
330 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000331 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000332 was always usable as a hash value before this patch. That's no longer
333 necessarily so.
334
335- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000336 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000337 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000338 #1454844)
339
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000340- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
341 involving generators that have paused outside of any ``try`` or ``with``
342 blocks. (In 2.5a1, a paused generator that was part of a reference
343 cycle could not be garbage collected, regardless of whether it was
344 paused in a ``try`` or ``with`` block.)

353 fails with an error condition.
354
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000355- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
356
357- Bug #1117761: bsddb.*open() no longer raises an exception when using
358 the cachesize parameter.
359
360- Bug #1149413: bsddb.*open() no longer raises an exception when using
361 a temporary db (file=None) with the 'n' flag to truncate on open.
362
363- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
364 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000365
Armin Rigoa9017c32006-04-19 11:50:27 +0000366- Patch #1062014: AF_UNIX sockets under Linux have a special
367 abstract namespace that is now fully supported.
368
Anthony Baxter51bcb682006-04-05 14:51:42 +0000369Library
370-------
371
Tim Peters711bf302006-04-25 03:31:36 +0000372- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
373 a doctest to be skipped (the code is not run, and the expected output
374 or exception is ignored).
375
Nick Coghlanda2268f2006-04-24 04:37:15 +0000376- Fixed contextlib.nested to cope with exceptions being raised and
377 caught inside exit handlers.
378
Greg Wardab05edc2006-04-23 03:47:58 +0000379- Updated optparse module to Optik 1.5.1 (allow numeric constants in
380 hex, octal, or binary; add ``append_const`` action; keep going if
381 gettext cannot be imported; added ``OptionParser.destroy()`` method;
382 added ``epilog`` for better help generation).
383
Tim Peters21fbd572006-04-21 21:18:10 +0000384- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
385 called from a thread spawned as a side effect of importing a module.
386
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000387- The pydoc module now supports documenting packages contained in
388 .zip or .egg files.
389
390- The pkgutil module now has several new utility functions, such
391 as ``walk_packages()`` to support working with packages that are either
392 in the filesystem or zip files.
393
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000394- The mailbox module can now modify and delete messages from
395 mailboxes, in addition to simply reading them. Thanks to Gregory

Anthony Baxtere29002c2006-04-12 12:07:31 +0000408- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
409 Windows. Bug #1469163.
410
Phillip J. Eby47032112006-04-11 01:07:43 +0000411- The warnings, linecache, inspect, traceback, site, and doctest modules
412 were updated to work correctly with modules imported from zipfiles or
413 via other PEP 302 __loader__ objects.

423 direct output to an alternate file-like object.
424
Anthony Baxter51bcb682006-04-05 14:51:42 +0000425Build
426-----
427
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000428- The Makefile now has a reindent target, which runs reindent.py on
429 the library.
430
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000431- Patch #1470875: Building Python with MS Free Compiler
432
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000433- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000434
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000435- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
436 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000437 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000438 CXX from --with-cxx-main, see description in README.
439
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000440- Patch #1429775: Link extension modules with the shared libpython.
441
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000442- Fixed a libffi build problem on MIPS systems.
443
Tim Peters8931ff12006-05-13 23:28:20 +0000444- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
445 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
446 and "%zu" for unsigned integers of type ``size_t``.
447
Anthony Baxter51bcb682006-04-05 14:51:42 +0000448Tests
449-----
450
Nick Coghlanda2268f2006-04-24 04:37:15 +0000451- test_contextlib now checks contextlib.nested can cope with exceptions
452 being raised and caught inside exit handlers.
453
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000454- test_cmd_line now checks operation of the -m and -c command switches
455
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000456- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
457 it separately and by hand. It also wasn't cleaning up its changes to
458 the current Decimal context.
459
Thomas Woutersabd08882006-04-26 15:53:30 +0000460- regrtest.py now has a -M option to run tests that test the new limits of
461 containers, on 64-bit architectures. Running these tests is only sensible
462 on 64-bit machines with more than two gigabytes of memory. The argument
463 passed is the maximum amount of memory for the tests to use.

472-------------
473
Tim Petersb06d28c2006-05-12 01:57:59 +0000474- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
475
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000476- PEP 343: Added Context Types section to the library reference
477 and attempted to bring other PEP 343 related documentation into
478 line with the implementation and/or python-dev discussions.
479
Tim Peters8dc73d22006-04-24 02:03:16 +0000480- Bug #1337990: clarified that ``doctest`` does not support examples
481 requiring both expected output and an exception.

Anthony Baxterebed3f62006-04-03 15:03:44 +0000487*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000488
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000489Core and builtins
490-----------------
491
Nick Coghlan43832302006-04-23 17:04:07 +0000492- PEP 338: -m command line switch now delegates to runpy.run_module
493 allowing it to support modules in packages and zipfiles
494
Martin v. Löwisc661b882006-04-20 04:54:23 +0000495- On Windows, .DLL is not an accepted file name extension for
496 extension modules anymore; extensions are only found if they
497 end in .PYD.
498
Martin v. Löwisea62d252006-04-03 10:56:49 +0000499- Bug #1421664: sys.stderr.encoding is now set to the same value as
500 sys.stdout.encoding.
501
Neal Norwitz92e212f2006-04-03 04:48:37 +0000502- __import__ accepts keyword arguments.
503
Georg Brandlccadf842006-03-31 18:54:53 +0000504- Patch #1460496: round() now accepts keyword arguments.
505
Anthony Baxter262c00a2006-03-30 10:53:17 +0000506- Fixed bug #1459029 - unicode reprs were double-escaped.
507
Hye-Shik Changd478f342006-03-23 12:32:36 +0000508- Patch #1396919: The system scope threads are reenabled on FreeBSD
509 5.4 and later versions.
510
Neal Norwitze98ccf62006-03-23 05:39:47 +0000511- Bug #1115379: Compiling a Unicode string with an encoding declaration
512 now gives a SyntaxError.
513
Georg Brandlabd1ff82006-03-18 07:59:59 +0000514- Previously, Python code had no easy way to access the contents of a
515 cell object. Now, a ``cell_contents`` attribute has been added
516 (closes patch #1170323).
517
Tim Peterscf79aac2006-03-16 01:14:46 +0000518- Patch #1123430: Python's small-object allocator now returns an arena to
519 the system ``free()`` when all memory within an arena becomes unused
520 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
521 freed. Some applications will see a drop in virtual memory size now,
522 especially long-running applications that, from time to time, temporarily
523 use a large number of small objects. Note that when Python returns an
524 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000525 platform C library will in turn return that memory to the operating system.
526 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000527 appears to be effective at least on Microsoft C and gcc-based systems.
528 Thanks to Evan Jones for hard work and patience.
529
Georg Brandl533ff6f2006-03-08 18:09:27 +0000530- Patch #1434038: property() now uses the getter's docstring if there is
531 no "doc" argument given. This makes it possible to legitimately use
532 property() as a decorator to produce a read-only property.
533
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000534- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
535 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
536 of requiring an int or long in slicing and a few other contexts, enabling
537 other objects (e.g. Numeric Python's integers) to be used as slice indices.
538
Neal Norwitz995acdf2006-03-07 05:01:00 +0000539- Fixed various bugs reported by Coverity's Prevent tool.
540
Brett Cannonbf364092006-03-01 04:25:17 +0000541- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
542 new exception base class, BaseException, which has a new message attribute.
543 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
544 Raising a string exception now raises a DeprecationWarning.
545
Thomas Woutersfb609f42006-02-28 16:37:25 +0000546- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
547 explicitly relative, using 'from .module import name' to mean 'from the same
548 package as this module is in. Imports without dots still default to the
549 old relative-then-absolute, unless 'from __future__ import
550 absolute_import' is used.
551
Brett Cannona7446e32006-02-27 23:39:10 +0000552- Properly check if 'warnings' raises an exception (usually when a filter set
553 to "error" is triggered) when raising a warning for raising string
554 exceptions.
555
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000556- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000557 The name was removed from Include/code.h.
558
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000559- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000560
Guido van Rossum1968ad32006-02-25 22:38:04 +0000561- Patch 1433928:
562 - The copy module now "copies" function objects (as atomic objects).
563 - dict.__getitem__ now looks for a __missing__ hook before raising
564 KeyError.
565
Tim Peters84ef21c2006-02-28 20:39:06 +0000566- PEP 343: with statement implemented. Needs ``from __future__ import
567 with_statement``. Use of 'with' as a variable will generate a warning.
568 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000569 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000570 The following objects have __context__ methods:
571 - The built-in file type.
572 - The thread.LockType type.
573 - The following types defined by the threading module:
574 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
575 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000576
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000577- Fix the encodings package codec search function to only search
578 inside its own package. Fixes problem reported in patch #1433198.
579
580 Note: Codec packages should implement and register their own
581 codec search function. PEP 100 has the details.
582
Tim Peters9ea89d22006-06-04 03:26:02 +0000583- PEP 353: Using ``Py_ssize_t`` as the index type.
584
585- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
586 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
587 now allow Python to make use of memory blocks exceeding 2**32 bytes for
588 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
589 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000590
Neal Norwitzfc76d632006-01-10 06:03:13 +0000591- Patch #1400181, fix unicode string formatting to not use the locale.
592 This is how string objects work. u'%f' could use , instead of .
593 for the decimal point. Now both strings and unicode always use periods.
594
Neal Norwitz671b9e32006-01-09 07:07:12 +0000595- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
596 configure would break checking curses.h.
597
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000598- Bug #959576: The pwd module is now builtin. This allows Python to be
599 built on UNIX platforms without $HOME set.
600
Neal Norwitzc10978f2005-12-19 06:07:16 +0000601- Bug #1072182, fix some potential problems if characters are signed.
602
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000603- Bug #889500, fix line number on SyntaxWarning for global declarations.
604
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000605- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
606
Neal Norwitze7214a12005-12-18 05:03:17 +0000607- Support for converting hex strings to floats no longer works.
608 This was not portable. float('0x3') now raises a ValueError.
609
Barry Warsaw2a38a862005-12-18 01:27:35 +0000610- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000611 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000612 is now displayed in interactive prompt banner.
613
Georg Brandlfa166682005-12-17 21:45:17 +0000614- Implementation of PEP 341 - Unification of try/except and try/finally.
615 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000616 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000617
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000618- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
619 now encodes backslash correctly.
620
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000621- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
622
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000623- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000624 and long longs.
625
Neal Norwitz67715f02005-11-09 06:59:35 +0000626- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000627 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000628 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000629
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000630- Replaced most Unicode charmap codecs with new ones using the
631 new Unicode translate string feature in the builtin charmap
632 codec; the codecs were created from the mapping tables available
633 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
634 encodings now include a mapping for the Apple logo)
635
Tim Peterse3547fd2005-12-16 23:13:57 +0000636- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000637
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000638- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000639
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000640- A new AST parser implementation was completed. The abstract
641 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000642 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000643
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000644- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000645 The following code now raises a SyntaxError: foo(a = i for i in range(10))
646
Neal Norwitz708e51a2005-10-03 04:48:15 +0000647- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
648
Neal Norwitz11bd1192005-10-03 00:54:56 +0000649- SF Bug #887946: fix segfault when redirecting stdin from a directory.
650 Provide a warning when a directory is passed on the command line.
651
Neal Norwitz40d37812005-10-02 01:48:49 +0000652- Fix segfault with invalid coding.
653
654- SF bug #772896: unknown encoding results in MemoryError.
655
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000656- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000657 supported a __len__() method which evaluated to False when the iterator
658 was empty.
659
Guido van Rossum630db602005-09-20 18:49:54 +0000660- On 64-bit platforms, when __len__() returns a value that cannot be
661 represented as a C int, raise OverflowError.
662
Skip Montanarof8948ca2005-09-19 03:54:46 +0000663- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000664 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000665
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000666- SF bug #893549: parsing keyword arguments was broken with a few format
667 codes.
668
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000669- Changes donated by Elemental Security to make it work on AIX 5.3
670 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
671 bug #105470: test_pwd fails on 64bit system (Opteron).
672
Guido van Rossum539c6622005-09-14 17:49:54 +0000673- Changes donated by Elemental Security to make it work on HP-UX 11 on
674 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
675
Georg Brandl4550b8d2005-08-26 06:43:52 +0000676- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000677 (fixes bug #1119418).
678
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000679- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
680
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000681- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
682 exceptions that cause a function to exit.
683
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000684- The implementation of set() and frozenset() was revised to use its
685 own internal data structure. Memory consumption is reduced by 1/3
686 and there are modest speed-ups as well. The API is unchanged.
687
Tim Petersde7990b2005-07-17 23:45:23 +0000688- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
689
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000690- SF bug #1229429: PyObject_CallMethod failed to decrement some
691 reference counts in some error exit cases.
692
Tim Petersecc6e6a2005-07-10 22:30:55 +0000693- SF bug #1185883: Python's small-object memory allocator took over
694 a block managed by the platform C library whenever a realloc specified
695 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000696 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000697 portable way to copy data from the C-managed block into Python's
698 small-object space without risking a memory fault. Python's small-object
699 realloc now leaves such blocks under the control of the platform C
700 realloc.
701
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000702- SF bug #1232517: An overflow error was not detected properly when
703 attempting to convert a large float to an int in os.utime().
704
Raymond Hettinger3296e692005-06-29 23:29:56 +0000705- SF bug #1224347: hex longs now print with lowercase letters just
706 like their int counterparts.
707
Michael W. Hudson188d4362005-06-20 16:52:57 +0000708- SF bug #1163563: the original fix for bug #1010677 ("thread Module
709 Breaks PyGILState_Ensure()") broke badly in the case of multiple
710 interpreter states; back out that fix and do a better job (see
711 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
712 for a longer write-up of the problem).
713
Michael W. Hudsondf888462005-06-03 14:41:55 +0000714- SF patch #1180995: marshal now uses a binary format by default when
715 serializing floats.
716
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000717- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
718 the routines that promise to produce IEEE 754 binary representations
719 of floats now simply copy bytes around.
720
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000721- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
722 278.
723
Brett Cannonc3647ac2005-04-26 03:45:26 +0000724- patch #1109424: int, long, float, complex, and unicode now check for the
725 proper magic slot for type conversions when subclassed. Previously the
726 magic slot was ignored during conversion. Semantics now match the way
727 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000728 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000729 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000730 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000731
Barry Warsawc8d907c2005-04-19 23:43:40 +0000732- Descriptors defined in C with a PyGetSetDef structure, where the setter is
733 NULL, now raise an AttributeError when attempting to set or delete the
734 attribute. Previously a TypeError was raised, but this was inconsistent
735 with the equivalent pure-Python implementation.
736
Michael W. Hudson774479c2005-04-18 08:46:17 +0000737- It is now safe to call PyGILState_Release() before
738 PyEval_InitThreads() (note that if there is reason to believe there
739 are multiple threads around you still must call PyEval_InitThreads()
740 before using the Python API; this fix is for extension modules that
741 have no way of knowing if Python is multi-threaded yet).
742
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000743- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
744 disabled caused a crash.
745
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000746- Bug #1165306: instancemethod_new allowed the creation of a method
747 with im_class == im_self == NULL, which caused a crash when called.
748
Tim Petersecc6e6a2005-07-10 22:30:55 +0000749- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000750 fixes the crash seen in bug #1165761
751
Raymond Hettinger96229b12005-03-11 06:49:40 +0000752- Added two new builtins, any() and all().
753
Brett Cannon409d8f22005-03-05 06:47:57 +0000754- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000755 (e.g., ``class C(): pass`` is no longer a syntax error).
756 Patch #1176012 added support to the 'parser' module and 'compiler' package
757 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000758
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000759- Patch #1115086: Support PY_LONGLONG in structmember.
760
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000761- Bug #1155938: new style classes did not check that __init__() was
762 returning None.
763
Tim Petersecc6e6a2005-07-10 22:30:55 +0000764- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000765 ('\') with a specific error message.
766
Martin v. Löwisff232d72005-03-03 09:24:38 +0000767- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
768
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000769- Bug #1124295: the __name__ attribute of file objects was
770 inadvertently made inaccessible in restricted mode.
771
Tim Petersecc6e6a2005-07-10 22:30:55 +0000772- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000773 an ferror() call.
774
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000775- min() and max() now support key= arguments with the same meaning as in
776 list.sort().
777
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000778- The peephole optimizer now performs simple constant folding in expressions:
779 (2+3) --> (5).
780
Raymond Hettingera422c342005-01-11 03:03:27 +0000781- set and frozenset objects can now be marshalled. SF #1098985.
782
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000783- Bug #1077106: Poor argument checking could cause memory corruption
784 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000785
Jeremy Hyltonab630502005-02-04 18:44:06 +0000786- The parser did not complain about future statements in illegal
787 positions. It once again reports a syntax error if a future
788 statement occurs after anything other than a doc string.
789
Neil Schemenauercf52c072005-08-12 17:34:58 +0000790- Change the %s format specifier for str objects so that it returns a
791 unicode instance if the argument is not an instance of basestring and
792 calling __str__ on the argument returns a unicode instance.
793
Tim Petersf4e69282006-02-27 17:15:31 +0000794- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
795 current thread state when the auto-GIL-state machinery knows about
796 it (since the thread state is being deleted, continuing to remember it
797 can't help, but can hurt if another thread happens to get created with
798 the same thread id).
799
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000800Extension Modules
801-----------------
802
Georg Brandl43f08a82006-03-31 18:01:16 +0000803- Patch #1380952: fix SSL objects timing out on consecutive read()s

817
818- The following modules were removed: regsub, reconvert, regex, regex_syntax.
819
820- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +0000821 is deprecated. The undocumented re.engine variable no longer exists.
822
Hye-Shik Changabb903f2006-03-13 10:20:08 +0000823- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
824 SS2 (single-shift 2) escape sequences correctly.
825
Martin v. Löwis480f1bb2006-03-09 23:38:20 +0000826- The unicodedata module was updated to the 4.1 version of the Unicode
827 database. The 3.2 version is still available as unicodedata.db_3_2_0
828 for applications that require this specific version (such as IDNA).
829
Neal Norwitzb62c4332006-03-04 18:35:47 +0000830- The timing module is no longer built by default. It was deprecated
831 in PEP 4 in Python 2.0 or earlier.
832
Guido van Rossum1968ad32006-02-25 22:38:04 +0000833- Patch 1433928: Added a new type, defaultdict, to the collections module.
834 This uses the new __missing__ hook behavior added to dict (see above).
835
Georg Brandldbd83392006-02-20 09:42:33 +0000836- Bug #854823: socketmodule now builds on Sun platforms even when
837 INET_ADDRSTRLEN is not defined.
838
Georg Brandlf4f44152006-02-18 22:29:33 +0000839- Patch #1393157: os.startfile() now has an optional argument to specify
840 a "command verb" to invoke on the file.
841
Neal Norwitz082b2df2006-02-07 07:04:46 +0000842- Bug #876637, prevent stack corruption when socket descriptor
843 is larger than FD_SETSIZE.
844
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +0000845- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
846 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
847 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
848
Martin v. Löwis57a34e82006-02-04 19:12:37 +0000849- Patch #1422385: The nis module now supports access to domains other
850 than the system default domain.
851
Martin v. Löwis14694662006-02-03 12:54:16 +0000852- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
853 are reported, the limit on path name lengths is removed, and stat reports
854 WindowsError now (instead of OSError).
855
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +0000856- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

932 for large or negative values.
933
Tim Petersecc6e6a2005-07-10 22:30:55 +0000934- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000987Library
988-------
989
Nick Coghlan43832302006-04-23 17:04:07 +0000990- PEP 338: new module runpy defines a run_module function to support
991 executing modules which provide access to source code or a code object
992 via the PEP 302 import mechanisms.
993
Anthony Baxter93f5b932006-04-03 08:05:07 +0000994- The email module's parsedate_tz function now sets the daylight savings

1002 in attribute values.
1003
Anthony Baxterc51ee692006-04-01 00:57:31 +00001004- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001005 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001006 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001007 module will not be built.
1008
Tim Petersc17976e2006-04-01 00:26:53 +00001009- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1010 aren't officially supported here, and trying to use them will probably
1011 raise an exception some day. But dicts have been allowed, and "mostly
1012 worked", so support for them won't go away without warning.
1013
Georg Brandl338ef7d2006-03-31 18:42:16 +00001014- Bug #1445068: getpass.getpass() can now be given an explicit stream
1015 argument to specify where to write the prompt.
1016
Georg Brandl22ec80b2006-03-31 18:25:44 +00001017- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1024
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00001025- Queue.Queue objects now support .task_done() and .join() methods
1026 to make it easier to monitor when daemon threads have completed
1027 processing all enqueued tasks. Patch #1455676.
1028
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001029- popen2.Popen objects now preserve the command in a .cmd attribute.

1032
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001033- email 4.0 package now integrated. This is largely the same as the email 3.0
1034 package that was included in Python 2.3, except that PEP 8 module names are
1035 now used (e.g. mail.message instead of email.Message). The MIME classes
1036 have been moved to a subpackage (e.g. email.mime.text instead of
1037 email.MIMEText). The old names are still supported for now. Several
1038 deprecated Message methods have been removed and lots of bugs have been
1039 fixed. More details can be found in the email package documentation.
1040
Walter Dörwald40108c92006-03-27 08:15:44 +00001041- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1042 (a subclass of tuple) that provides incremental decoders and encoders
1043 (a way to use stateful codecs without the stream API). Python functions
1044 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1045 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1046 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001047
Walter Dörwald067db482006-03-15 22:17:27 +00001048- Patch #1359365: Calling next() on a closed StringIO.String object raises
1049 a ValueError instead of a StopIteration now (like file and cString.String do).
1050 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1051 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001052
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001053- A regrtest option -w was added to re-run failed tests in verbose mode.

1063
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001064- PEP 343: new module contextlib.py defines decorator @contextmanager
1065 and helpful context managers nested() and closing().
1066
Martin v. Löwis415ed932006-02-27 19:56:30 +00001067- The compiler package now supports future imports after the module docstring.

Martin v. Löwis3e865952006-01-24 15:51:21 +00001101 specifications, raises IOErrors when proxies for unsupported protocols
1102 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00001125 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1126 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1127 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1128 Ronald L. Rivest offered this advice for Python:
1129
1130 "The consensus of researchers in this area (at least as
1131 expressed at the NIST Hash Function Workshop 10/31/05),
1132 is that SHA-256 is a good choice for the time being, but
1133 that research should continue, and other alternatives may
1134 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001135
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001136- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandlb9256022005-08-24 18:46:39 +00001182- Patch #1062060: urllib.urlretrieve() now raises a new exception, named
1183 ContentTooShortException, when the actually downloaded size does not
1184 match the Content-Length header.
1185
Martin v. Löwis0a5d4a22005-08-24 14:55:22 +00001186- Bug #1121494: distutils.dir_utils.mkpath now accepts Unicode strings.
1187
Martin v. Löwis56066d22005-08-24 07:38:12 +00001188- Bug #1178484: Return complete lines from codec stream readers
1189 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001190 correct line numbers for decoding errors in source code.

1213 to W3C name (404 -> 'Not Found'). RFE #1216944.
1214
Georg Brandl9e43acf2005-07-04 17:16:07 +00001215- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1216 as this can cause problems with apps closing all file descriptors.
1217
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001218- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001219 it can be missing in embedded interpreters

1227
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00001228- The tokenize module now detects and reports indentation errors.
1229 Bug #1224621.
1230
Raymond Hettinger68c04532005-06-10 11:05:19 +00001231- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001232 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001233 the generate_tokens() function now accepts a callable argument that
1234 terminates by raising StopIteration.
1235
Georg Brandl9166e1a2005-06-04 09:20:03 +00001236- Bug #1196315: fix weakref.WeakValueDictionary constructor.
1237
Georg Brandl268e61c2005-06-03 14:28:50 +00001238- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first

1240
Skip Montanaro174dd222005-05-14 20:54:16 +00001241- Patch #1120353: The xmlrpclib module provides better, more transparent,
1242 support for datetime.{datetime,date,time} objects. With use_datetime set
1243 to True, applications shouldn't have to fiddle with the DateTime wrapper
1244 class at all.
1245
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001246- distutils.commands.upload was added to support uploading distribution
1247 files to PyPI.
1248
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001249- distutils.commands.register now encodes the data as UTF-8 before posting
1250 them to PyPI.
1251
Raymond Hettinger267b8682005-03-27 10:47:39 +00001252- decimal operator and comparison methods now return NotImplemented
1253 instead of raising a TypeError when interacting with other types. This
1254 allows other classes to implement __radd__ style methods and have them
1255 work as expected.
1256
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001257- Bug #1163325: Decimal infinities failed to hash. Attempting to
1258 hash a NaN raised an InvalidOperation instead of a TypeError.
1259
Tim Petersecc6e6a2005-07-10 22:30:55 +00001260- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001261 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1262

Raymond Hettingerbab41432005-02-05 01:31:19 +00001293- Fixed bug in a NameError bug in cookielib. Patch #1116583.
1294
Guido van Rossumd0641422005-02-03 15:01:24 +00001295- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1296 disables recursive traversal through instance attributes, which can
1297 be exploited in various ways.
1298
Tim Peterse3547fd2005-12-16 23:13:57 +00001299- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001300 flags on the HTTP listening socket.
1301
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001302- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1303 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1304
Tim Peterse3547fd2005-12-16 23:13:57 +00001305- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001306 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1307
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001308- Bug #1110478: Revert os.environ.update to do putenv again.
1309
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001310- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1311
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001312- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1313
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001314- Enhancements to the csv module:
1315
1316 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001317 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001318 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001319 + Dialect parameter parsing has been re-implemented to improve error
1320 reporting.
1321 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1322 dictates.
1323 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001324 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001325 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001326 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1327 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001328 + reader now allows \r characters to be quoted (previously it only allowed
1329 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001330 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001331 + Dialect classes passed to the module are no longer instantiated by
1332 the module before being parsed (the former validation scheme required
1333 this, but the mechanism was unreliable).
1334 + The dialect registry now contains instances of the internal
1335 C-coded dialect type, rather than references to python objects.
1336 + the internal c-coded dialect type is now immutable.
1337 + register_dialect now accepts the same keyword dialect specifications
1338 as the reader and writer, allowing the user to register dialects
1339 without first creating a dialect class.
1340 + a configurable limit to the size of parsed fields has been added -
1341 previously, an unmatched quote character could result in the entire
1342 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001343 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001344 the parser field size limit (returning the former limit). The initial
1345 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001346 + A line_num attribute has been added to the reader object, which tracks
1347 the number of lines read from the source iterator. This is not
1348 the same as the number of records returned, as records can span
1349 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001350 + reader and writer objects were not being registered with the cyclic-GC.
1351 This has been fixed.
1352
Brett Cannone6539c42005-01-08 02:43:53 +00001353- _DummyThread objects in the threading module now delete self.__block that is
1354 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1355 lock primitives tend to be limited in number and thus should not be wasted on
1356 a _DummyThread object. Fixes bug #1089632.
1357
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001358- The imghdr module now detects Exif files.
1359
Raymond Hettinger6065d322004-12-20 23:51:53 +00001360- StringIO.truncate() now correctly adjusts the size attribute.
1361 (Bug #951915).
1362
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001363- locale.py now uses an updated locale alias table (built using
1364 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1365 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001366 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001367
Raymond Hettinger3557f422004-12-07 12:02:02 +00001368- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1369
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001370- the pickle module no longer accepts the deprecated None option in the
1371 args tuple returned by __reduce__().
1372
Brett Cannon84667c02004-12-07 03:25:18 +00001373- optparse now optionally imports gettext. This allows its use in setup.py.
1374
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001375- the pickle module no longer uses the deprecated bin parameter.
1376
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001377- the shelve module no longer uses the deprecated binary parameter.
1378
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001379- the pstats module no longer uses the deprecated ignore() method.
1380
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001381- the filecmp module no longer uses the deprecated use_statcache argument.
1382
Raymond Hettinger664347b2004-12-04 21:21:53 +00001383- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1384 extended or overridden by subclasses. Formerly, the subclassed method would
1385 be ignored by the rest of the module. (Bug #1078905).
1386
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001387- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001388 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001389
Walter Dörwald36733692004-12-22 12:50:50 +00001390- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1391 once when a size argument is given. This prevents a buffer overflow in the
1392 tokenizer with very long source lines.
1393
Barry Warsaw538561e2006-01-01 21:48:54 +00001394- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1395 immediately after creating the object, without any intervening
1396 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001397
Skip Montanaro05885812005-01-16 20:48:27 +00001398- The reconvert.quote function can now emit triple-quoted strings. The
1399 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001400
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001401- ``UserString.MutableString`` now supports negative indices in
1402 ``__setitem__`` and ``__delitem__``
1403
Greg Ward40407942005-03-05 02:53:17 +00001404- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1405 correctly.
1406
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001407- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1408 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1409 character even if the user has passed a size parameter to get a proper
1410 line ending. Remove the special handling of a "\r\n" that has been split
1411 between two lines.
1412
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001413- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1414 about illegal code points. The codec now supports PEP 293 style error
1415 handlers.
1416
Walter Dörwald78a78b02005-09-01 12:04:29 +00001417- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001418 from the input stream, so that the output is a byte string in the correct
1419 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001420
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001421- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1422 considering it exactly like a '*'.
1423
Walter Dörwald007f8df2005-10-09 19:42:27 +00001424- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1425 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001426
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001427- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1428
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001429- Patch #1413711: Certain patterns of differences were making difflib
1430 touch the recursion limit.
1431
Walter Dörwald58917a62006-03-31 15:26:22 +00001432- Bug #947906: An object oriented interface has been added to the calendar
1433 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001434 called as a script (e.g. via ``python -mcalendar``). Localized month and
1435 weekday names can be ouput (even if an exotic encoding is used) using
1436 special classes that use unicode.

1439-----
1440
Neal Norwitz602d3392006-03-31 08:21:40 +00001441- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1442 by using -mieee gcc option.
1443

1445
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001446- Build support for Win64-AMD64 was added.
1447
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001448- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1449
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001450- Patch #881820: look for openpty and forkpty also in libbsd.
1451
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001452- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1453 The zlib module is now builtin on Windows.
1454
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001455- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1456
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001457- Bug #1189330: configure did not correctly determine the necessary
1458 value of LINKCC if python was built with GCC 4.0.
1459
Trent Mick8321b422005-07-26 02:29:21 +00001460- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1461 vulnerability in zlib 1.2.1 and 1.2.2.
1462
Brett Cannon08cd5982005-04-24 22:26:38 +00001463- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1464 flags that change binary compatibility. Changes were also made to
1465 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001466 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001467
Bob Ippolitoed233462005-03-29 13:47:59 +00001468- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1469 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1470 no longer exists). This configure patch makes things right.
1471
Martin v. Löwise2713be2005-03-08 15:03:08 +00001472- Bug #1158607: Build with --disable-unicode again.
1473
Brett Cannon46d96232005-02-16 00:07:19 +00001474- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1475 defined. Discovered as a result of not being able to build on OS X.
1476
Brett Cannon516592f2004-12-07 00:42:59 +00001477- setup.py now uses the directories specified in LDFLAGS using the -L option
1478 and in CPPFLAGS using the -I option for adding library and include
1479 directories, respectively, for compiling extension modules against. This has
1480 led to the core being compiled using the values in CPPFLAGS. It also removes
1481 the need for the special-casing of both DarwinPorts and Fink for darwin since
1482 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1483 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1484 Fink, ``-I/opt/local/include`` for DarwinPorts).
1485
Brett Cannon43802422005-02-10 20:48:03 +00001486- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1487 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1488 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1489 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001491C API
1492-----
1493
Tim Petersc9d78aa2006-03-26 23:27:58 +00001494- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1495 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1496 is obtained via the ``PyObject_`` family, it must be released via the
1497 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1498 always been officially true, but when Python's small-object allocator was
1499 introduced, an attempt was made to cater to a few extension modules
1500 discovered at the time that obtained memory via ``PyObject_New`` but
1501 released it via ``PyMem_DEL``. It's years later, and if such code still
1502 exists it will fail now (probably with segfaults, but calling wrong
1503 low-level memory management functions can yield many symptoms).
1504
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001505- Added a C API for set and frozenset objects.
1506

1508
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001509- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1510 mapping argument now. This string is used as a mapping table. Byte values
1511 greater than the length of the string and 0xFFFE are treated as undefined
1512 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00001518- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001519
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001520- Patch #1276356: New resource "urlfetch" is implemented. This enables
1521 even impatient people to run tests that require remote files.
