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
Georg Brandla56b9152006-06-19 06:35:54 +000015- Patch #1507676: Error messages returned by invalid abstract object operations
16 (such as iterating over an integer) have been improved and now include the
17 type of the offending object to help with debugging.
18
Brett Cannonea3912b2006-06-13 21:46:41 +000019- Bug #992017: A classic class that defined a __coerce__() method that returned
20 its arguments swapped would infinitely recurse and segfault the interpreter.
21
Neal Norwitz909eb122006-06-12 02:13:21 +000022- Fix the socket tests so they can be run concurrently.
23
Neal Norwitzb9845e72006-06-12 02:11:18 +000024- Removed 5 integers from C frame objects (PyFrameObject).
25 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
26
Brett Cannon22565aa2006-06-09 22:31:23 +000027- Bug #532646: object.__call__() will continue looking for the __call__
28 attribute on objects until one without one is found. This leads to recursion
29 when you take a class and set its __call__ attribute to an instance of the
30 class. Originally fixed for classic classes, but this fix is for new-style.
31 Removes the infinite_rec_3 crasher.
32
Georg Brandl24250812006-06-09 18:45:48 +000033- The string and unicode methods startswith() and endswith() now accept
34 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
35
Brett Cannonde3b0522006-06-08 17:00:45 +000036- Buffer objects, at the C level, never used the char buffer
37 implementation even when the char buffer for the wrapped object was
38 explicitly requested (originally returned the read or write buffer).
39 Now a TypeError is raised if the char buffer is not present but is
40 requested.
41
Georg Brandlddbaa662006-06-04 21:56:52 +000042- Patch #1346214: Statements like "if 0: suite" are now again optimized
43 away like they were in Python 2.4.
44
Georg Brandlb7c8f542006-05-27 12:30:25 +000045- Builtin exceptions are now full-blown new-style classes instead of
46 instances pretending to be classes, which speeds up exception handling
47 by about 80% in comparison to 2.5a2.
48
Martin v. Löwisd004fc82006-05-27 08:36:52 +000049- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
50 Unicode 4.1.
51
Georg Brandlf4ef1162006-05-26 18:03:31 +000052- Patch #921466: sys.path_importer_cache is now used to cache valid and
53 invalid file paths for the built-in import machinery which leads to
54 fewer open calls on startup.
55
Tim Peters696cf432006-05-24 21:10:40 +000056- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
57 of-2 bases. The largest speedup is for inputs with about 1000 decimal
58 digits. Conversion from non-power-of-2 bases remains quadratic-time in
59 the number of input digits (it was and remains linear-time for bases
60 2, 4, 8, 16 and 32).
61
Tim Petersb713ec22006-05-23 18:45:30 +000062- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
63 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
64 an integer close to ``sys.maxint``. This was repaired by patch
65 #1335972, which also gives a nice speedup.
66
Richard Jonescebbefc2006-05-23 18:28:17 +000067- Patch #1337051: reduced size of frame objects.
68
69- PyErr_NewException now accepts a tuple of base classes as its
70 "base" parameter.
71
Richard Jones7c88dcc2006-05-23 10:37:38 +000072- Patch #876206: function call speedup by retaining allocated frame
73 objects.
74
Georg Brandl7b90e162006-05-18 07:01:27 +000075- Bug #1462152: file() now checks more thoroughly for invalid mode
76 strings and removes a possible "U" before passing the mode to the
77 C library function.
78
Neal Norwitz1004a532006-05-15 07:17:23 +000079- Patch #1488312, Fix memory alignment problem on SPARC in unicode
80
Neal Norwitz373f0a72006-05-15 07:04:36 +000081- Bug #1487966: Fix SystemError with conditional expression in assignment
82
Martin v. Löwis879768d2006-05-11 13:28:43 +000083- WindowsError now has two error code attributes: errno, which carries
84 the error values from errno.h, and winerror, which carries the error
85 values from winerror.h. Previous versions put the winerror.h values
86 (from GetLastError()) into the errno attribute.
87
Martin v. Löwis77736712006-05-04 05:51:03 +000088- Patch #1475845: Raise IndentationError for unexpected indent.
89
Neal Norwitzc4edb0e2006-05-02 04:43:14 +000090- Patch #1479181: split open() and file() from being aliases for each other.
91
Tim Peters44bd9862006-06-01 13:49:23 +000092- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
93 methods were always silently ignored by dictionaries when comparing keys.
94 They are now passed through (except when using the C API function
95 ``PyDict_GetItem()``, whose semantics did not change).
96
97- Bug #1456209: In some obscure cases it was possible for a class with a
98 custom ``__eq__()`` method to confuse dict internals when class instances
99 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
100 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000102Extension Modules
103-----------------
104
Brett Cannon6ee7d012006-06-08 16:23:04 +0000105- Change binascii.hexlify to accept a read-only buffer instead of only a char
106 buffer and actually follow its documentation.
107
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000108- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
109
Nick Coghlanc649ec52006-05-29 12:43:05 +0000110- Patch #1478788 (modified version): The functional extension module has
111 been renamed to _functools and a functools Python wrapper module added.
112 This provides a home for additional function related utilities that are
113 not specifically about functional programming. See PEP 309.
114
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000115- Patch #1493701: performance enhancements for struct module.
116
Georg Brandl378d5922006-05-17 14:26:50 +0000117- Patch #1490224: time.altzone is now set correctly on Cygwin.
118
Georg Brandl8d3342b2006-05-16 07:38:27 +0000119- Patch #1435422: zlib's compress and decompress objects now have a
120 copy() method.
121
Andrew MacIntyre92913322006-06-13 15:04:24 +0000122- Patch #1454481: thread stack size is now tunable at runtime for thread
123 enabled builds on Windows and systems with Posix threads support.
124
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000125- On Win32, os.listdir now supports arbitrarily-long Unicode path names
126 (up to the system limit of 32K characters).
127
128- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
129 As a result, these functions now raise WindowsError instead of OSError.
130
Tim Peters7a822da2006-05-25 21:50:17 +0000131- ``time.clock()`` on Win64 should use the high-performance Windows
132 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
133 Windows platforms).
134
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000135- Calling Tk_Init twice is refused if the first call failed as that
136 may deadlock.
137
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000138- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
139 accept it without potentially using an uninitialized pointer.
140
141- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
142 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
143 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000144
Gregory P. Smith372b5832006-06-05 18:48:21 +0000145- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000146 [pybsddb project SF patch number 1466734]
147
Gregory P. Smith372b5832006-06-05 18:48:21 +0000148- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
149 parameter is supplied. [SF pybsddb bug #1477863]
150
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000151- bsddb: the __len__ method of a DB object has been fixed to return correct
152 results. It could previously incorrectly return 0 in some cases.
153 Fixes SF bug 1493322 (pybsddb bug 1184012).
154
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000155- bsddb: the bsddb.dbtables Modify method now raises the proper error and
156 aborts the db transaction safely when a modifier callback fails.
157 Fixes SF python patch/bug #1408584.
158
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000159- bsddb: multithreaded DB access using the simple bsddb module interface
160 now works reliably. It has been updated to use automatic BerkeleyDB
161 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
162 database calls that would previously deadlock. [SF python bug #775414]
163
Ronald Oussoren143cefb2006-06-15 08:14:18 +0000164- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +0000165
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000166

168-------
169
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000170- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
171 functions.
172
Martin v. Löwis3798da02006-06-17 18:44:27 +0000173- Patch #812986: Update turtle output even if not tracing.
174
Martin v. Löwis92733be2006-06-17 09:25:15 +0000175- Patch #1494750: Destroy master after deleting children in
176 Tkinter.BaseWidget.
177
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000178- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
179
Martin v. Löwis337487e2006-06-17 09:15:14 +0000180- Patch #763580: Add name and value arguments to Tkinter variable
181 classes.
182
Georg Brandl83cc0d02006-06-14 08:50:03 +0000183- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
184 mime.types file for determining MIME types.
185
Georg Brandl2605ca82006-06-14 06:08:31 +0000186- Bug #1339007: Shelf objects now don't raise an exception in their
187 __del__ method when initialization failed.
188
Martin v. Löwisd8251432006-06-14 05:21:04 +0000189- Patch #1455898: The MBCS codec now supports the incremental mode for
190 double-byte encodings.
191
Tim Peters43898b42006-06-14 04:09:25 +0000192- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
193 guarantee that adjacent triples in the return list always describe
194 non-adjacent blocks. Previously, a pair of matching blocks could end
195 up being described by multiple adjacent triples that formed a partition
196 of the matching pair.
197
Greg Ward0e0c9f42006-06-11 16:24:11 +0000198- Bug #1498146: fix optparse to handle Unicode strings in option help,
199 description, and epilog.
200
Greg Wardd1c797e2006-06-11 14:42:41 +0000201- Bug #1366250: minor optparse documentation error.
202
Greg Ward7f547402006-06-11 00:40:49 +0000203- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
204 clarify docs.
205
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000206- The wsgiref package has been added to the standard library.
207
Nick Coghlan676725d2006-06-08 13:54:49 +0000208- The functions update_wrapper() and wraps() have been added to the functools
209 module. These make it easier to copy relevant metadata from the original
210 function when writing wrapper functions.
211
Tim Petersd6a9eef2006-06-05 01:48:21 +0000212- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
213 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000214
Martin v. Löwis3f767792006-06-04 19:36:28 +0000215- Patch #1359618: Speed up charmap encoder by using a trie structure
216 for lookup.
217
Tim Petersd609b1a2006-06-02 23:22:51 +0000218- The functions in the ``pprint`` module now sort dictionaries by key
219 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
220 if and only if its display required more than one line, although that
221 wasn't documented. The new behavior increases predictability; e.g.,
222 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
223
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000224- Patch #1497027: try HTTP digest auth before basic auth in urllib2
225 (thanks for J. J. Lee).
226
Georg Brandl2b330372006-05-28 20:23:12 +0000227- Patch #1496206: improve urllib2 handling of passwords with respect to
228 default HTTP and HTTPS ports.
229
George Yoshidaf3c65de2006-05-28 16:39:09 +0000230- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
231
Bob Ippolito7298f272006-05-23 18:43:47 +0000232- Patch #1281707: speed up gzip.readline.
233
Georg Brandlb89316f2006-05-17 15:51:16 +0000234- Patch #1180296: Two new functions were added to the locale module:
235 format_string() to get the effect of "format % items" but locale-aware,
236 and currency() to format a monetary number with currency sign.
237
Georg Brandle3a25832006-05-17 14:56:04 +0000238- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
239 and several features added, such as speed and geometry control.
240
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000241- Patch #1488881: add support for external file objects in bz2 compressed
242 tarfiles.
243
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000244- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
245 stdout arguments, making it possible to redirect input and output
246 for remote debugging.
247
248- Patch #1484695: Update the tarfile module to version 0.8. This fixes
249 a couple of issues, notably handling of long file names using the
250 GNU LONGNAME extension.
251
252- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
253 new flag when ``name`` is already the name of an option flag.
254
255- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
256 package.
257
258- Patch #1472854: make the rlcompleter.Completer class usable on non-
259 UNIX platforms.
260
261- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
262
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +0000263- Bug #1472827: correctly escape newlines and tabs in attribute values in
264 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000294What's New in Python 2.5 alpha 2?
295=================================
296
297*Release date: 27-APR-2006*
298
299Core and builtins
300-----------------
301
Thomas Heller1b046642006-04-18 18:51:06 +0000302- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
303 by converting these apis from macros into exported functions again:
304
305 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
306 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
307 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
308 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
309 PyRun_String Py_CompileString
310
Martin v. Löwis45294a92006-04-18 06:24:08 +0000311- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
312
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000313- All uses of PyStructSequence_InitType have been changed to initialize
314 the type objects only once, even if the interpreter is initialized
315 multiple times.
316
Neal Norwitz61546162006-04-14 05:20:28 +0000317- Bug #1454485, array.array('u') could crash the interpreter. This was
318 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
319 to unicode when it didn't make sense. 'u#' now requires a unicode string.
320
321- Py_UNICODE is unsigned. It was always documented as unsigned, but
322 due to a bug had a signed value in previous versions.
323
Tim Peters3a5e8b12006-04-11 01:44:07 +0000324- Patch #837242: ``id()`` of any Python object always gives a positive
325 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
326 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000327 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000328 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000329
Tim Peters3a5e8b12006-04-11 01:44:07 +0000330 def __hash__(self):
331 return id(self) # WRONG
332
333 because a hash result must be a (short) Python int but it was always
334 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000335 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000336 was always usable as a hash value before this patch. That's no longer
337 necessarily so.
338
339- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000340 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000341 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000342 #1454844)
343
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000344- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
345 involving generators that have paused outside of any ``try`` or ``with``
346 blocks. (In 2.5a1, a paused generator that was part of a reference
347 cycle could not be garbage collected, regardless of whether it was
348 paused in a ``try`` or ``with`` block.)

365 a temporary db (file=None) with the 'n' flag to truncate on open.
366
367- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
368 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000369
Armin Rigoa9017c32006-04-19 11:50:27 +0000370- Patch #1062014: AF_UNIX sockets under Linux have a special

379
Nick Coghlanda2268f2006-04-24 04:37:15 +0000380- Fixed contextlib.nested to cope with exceptions being raised and
381 caught inside exit handlers.
382
Greg Wardab05edc2006-04-23 03:47:58 +0000383- Updated optparse module to Optik 1.5.1 (allow numeric constants in
384 hex, octal, or binary; add ``append_const`` action; keep going if
385 gettext cannot be imported; added ``OptionParser.destroy()`` method;
386 added ``epilog`` for better help generation).
387
Tim Peters21fbd572006-04-21 21:18:10 +0000388- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
389 called from a thread spawned as a side effect of importing a module.
390
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000391- The pydoc module now supports documenting packages contained in
392 .zip or .egg files.
393
394- The pkgutil module now has several new utility functions, such
395 as ``walk_packages()`` to support working with packages that are either
396 in the filesystem or zip files.
397
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000398- The mailbox module can now modify and delete messages from

430-----
431
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000432- The Makefile now has a reindent target, which runs reindent.py on
433 the library.
434
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000435- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis0f48d982006-04-14 14:34:26 +0000439- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
440 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000441 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000442 CXX from --with-cxx-main, see description in README.
443
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000444- Patch #1429775: Link extension modules with the shared libpython.
445
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000446- Fixed a libffi build problem on MIPS systems.
447
Tim Peters8931ff12006-05-13 23:28:20 +0000448- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
449 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
450 and "%zu" for unsigned integers of type ``size_t``.
451

453-----
454
Nick Coghlanda2268f2006-04-24 04:37:15 +0000455- test_contextlib now checks contextlib.nested can cope with exceptions
456 being raised and caught inside exit handlers.
457
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000458- test_cmd_line now checks operation of the -m and -c command switches
459
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000460- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
461 it separately and by hand. It also wasn't cleaning up its changes to
462 the current Decimal context.
463
Thomas Woutersabd08882006-04-26 15:53:30 +0000464- regrtest.py now has a -M option to run tests that test the new limits of
465 containers, on 64-bit architectures. Running these tests is only sensible
466 on 64-bit machines with more than two gigabytes of memory. The argument
467 passed is the maximum amount of memory for the tests to use.

476-------------
477
Tim Petersb06d28c2006-05-12 01:57:59 +0000478- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
479
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000480- PEP 343: Added Context Types section to the library reference
481 and attempted to bring other PEP 343 related documentation into
482 line with the implementation and/or python-dev discussions.
483
Tim Peters8dc73d22006-04-24 02:03:16 +0000484- Bug #1337990: clarified that ``doctest`` does not support examples
485 requiring both expected output and an exception.

Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000492
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000493Core and builtins
494-----------------
495
Nick Coghlan43832302006-04-23 17:04:07 +0000496- PEP 338: -m command line switch now delegates to runpy.run_module
497 allowing it to support modules in packages and zipfiles
498
Martin v. Löwisc661b882006-04-20 04:54:23 +0000499- On Windows, .DLL is not an accepted file name extension for
500 extension modules anymore; extensions are only found if they
501 end in .PYD.
502
Martin v. Löwisea62d252006-04-03 10:56:49 +0000503- Bug #1421664: sys.stderr.encoding is now set to the same value as
504 sys.stdout.encoding.
505
Neal Norwitz92e212f2006-04-03 04:48:37 +0000506- __import__ accepts keyword arguments.
507
Georg Brandlccadf842006-03-31 18:54:53 +0000508- Patch #1460496: round() now accepts keyword arguments.
509
Anthony Baxter262c00a2006-03-30 10:53:17 +0000510- Fixed bug #1459029 - unicode reprs were double-escaped.
511
Hye-Shik Changd478f342006-03-23 12:32:36 +0000512- Patch #1396919: The system scope threads are reenabled on FreeBSD
513 5.4 and later versions.
514
Neal Norwitze98ccf62006-03-23 05:39:47 +0000515- Bug #1115379: Compiling a Unicode string with an encoding declaration
516 now gives a SyntaxError.
517
Georg Brandlabd1ff82006-03-18 07:59:59 +0000518- Previously, Python code had no easy way to access the contents of a
519 cell object. Now, a ``cell_contents`` attribute has been added
520 (closes patch #1170323).
521
Tim Peterscf79aac2006-03-16 01:14:46 +0000522- Patch #1123430: Python's small-object allocator now returns an arena to
523 the system ``free()`` when all memory within an arena becomes unused
524 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
525 freed. Some applications will see a drop in virtual memory size now,
526 especially long-running applications that, from time to time, temporarily
527 use a large number of small objects. Note that when Python returns an
528 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000529 platform C library will in turn return that memory to the operating system.
530 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000531 appears to be effective at least on Microsoft C and gcc-based systems.
532 Thanks to Evan Jones for hard work and patience.
533
Georg Brandl533ff6f2006-03-08 18:09:27 +0000534- Patch #1434038: property() now uses the getter's docstring if there is
535 no "doc" argument given. This makes it possible to legitimately use
536 property() as a decorator to produce a read-only property.
537
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000538- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
539 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
540 of requiring an int or long in slicing and a few other contexts, enabling
541 other objects (e.g. Numeric Python's integers) to be used as slice indices.
542
Neal Norwitz995acdf2006-03-07 05:01:00 +0000543- Fixed various bugs reported by Coverity's Prevent tool.
544
Brett Cannonbf364092006-03-01 04:25:17 +0000545- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
546 new exception base class, BaseException, which has a new message attribute.
547 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
548 Raising a string exception now raises a DeprecationWarning.
549
Thomas Woutersfb609f42006-02-28 16:37:25 +0000550- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
551 explicitly relative, using 'from .module import name' to mean 'from the same
552 package as this module is in. Imports without dots still default to the
553 old relative-then-absolute, unless 'from __future__ import
554 absolute_import' is used.
555
Brett Cannona7446e32006-02-27 23:39:10 +0000556- Properly check if 'warnings' raises an exception (usually when a filter set
557 to "error" is triggered) when raising a warning for raising string
558 exceptions.
559
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000560- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000561 The name was removed from Include/code.h.
562
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000563- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000564
Guido van Rossum1968ad32006-02-25 22:38:04 +0000565- Patch 1433928:
566 - The copy module now "copies" function objects (as atomic objects).
567 - dict.__getitem__ now looks for a __missing__ hook before raising
568 KeyError.
569
Tim Peters84ef21c2006-02-28 20:39:06 +0000570- PEP 343: with statement implemented. Needs ``from __future__ import
571 with_statement``. Use of 'with' as a variable will generate a warning.
572 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000573 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000574 The following objects have __context__ methods:
575 - The built-in file type.
576 - The thread.LockType type.
577 - The following types defined by the threading module:
578 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
579 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +0000580
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000581- Fix the encodings package codec search function to only search
582 inside its own package. Fixes problem reported in patch #1433198.
583
584 Note: Codec packages should implement and register their own
585 codec search function. PEP 100 has the details.
586
Tim Peters9ea89d22006-06-04 03:26:02 +0000587- PEP 353: Using ``Py_ssize_t`` as the index type.
588
589- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
590 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
591 now allow Python to make use of memory blocks exceeding 2**32 bytes for
592 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
593 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000594
Neal Norwitzfc76d632006-01-10 06:03:13 +0000595- Patch #1400181, fix unicode string formatting to not use the locale.
596 This is how string objects work. u'%f' could use , instead of .
597 for the decimal point. Now both strings and unicode always use periods.
598
Neal Norwitz671b9e32006-01-09 07:07:12 +0000599- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
600 configure would break checking curses.h.
601
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000602- Bug #959576: The pwd module is now builtin. This allows Python to be
603 built on UNIX platforms without $HOME set.
604
Neal Norwitzc10978f2005-12-19 06:07:16 +0000605- Bug #1072182, fix some potential problems if characters are signed.
606
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000607- Bug #889500, fix line number on SyntaxWarning for global declarations.
608
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000609- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
610
Neal Norwitze7214a12005-12-18 05:03:17 +0000611- Support for converting hex strings to floats no longer works.
612 This was not portable. float('0x3') now raises a ValueError.
613
Barry Warsaw2a38a862005-12-18 01:27:35 +0000614- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000615 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000616 is now displayed in interactive prompt banner.
617
Georg Brandlfa166682005-12-17 21:45:17 +0000618- Implementation of PEP 341 - Unification of try/except and try/finally.
619 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000620 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000621
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000622- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
623 now encodes backslash correctly.
624
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000625- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
626
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000627- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000628 and long longs.
629
Neal Norwitz67715f02005-11-09 06:59:35 +0000630- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000631 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000632 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000633
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000634- Replaced most Unicode charmap codecs with new ones using the
635 new Unicode translate string feature in the builtin charmap
636 codec; the codecs were created from the mapping tables available
637 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
638 encodings now include a mapping for the Apple logo)
639
Tim Peterse3547fd2005-12-16 23:13:57 +0000640- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000641
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000642- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000643
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000644- A new AST parser implementation was completed. The abstract
645 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000646 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000647
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000648- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000649 The following code now raises a SyntaxError: foo(a = i for i in range(10))
650
Neal Norwitz708e51a2005-10-03 04:48:15 +0000651- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
652
Neal Norwitz11bd1192005-10-03 00:54:56 +0000653- SF Bug #887946: fix segfault when redirecting stdin from a directory.
654 Provide a warning when a directory is passed on the command line.
655
Neal Norwitz40d37812005-10-02 01:48:49 +0000656- Fix segfault with invalid coding.
657
658- SF bug #772896: unknown encoding results in MemoryError.
659
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000660- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000661 supported a __len__() method which evaluated to False when the iterator
662 was empty.
663
Guido van Rossum630db602005-09-20 18:49:54 +0000664- On 64-bit platforms, when __len__() returns a value that cannot be
665 represented as a C int, raise OverflowError.
666
Skip Montanarof8948ca2005-09-19 03:54:46 +0000667- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000668 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000669
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000670- SF bug #893549: parsing keyword arguments was broken with a few format
671 codes.
672
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000673- Changes donated by Elemental Security to make it work on AIX 5.3
674 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
675 bug #105470: test_pwd fails on 64bit system (Opteron).
676
Guido van Rossum539c6622005-09-14 17:49:54 +0000677- Changes donated by Elemental Security to make it work on HP-UX 11 on
678 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
679
Georg Brandl4550b8d2005-08-26 06:43:52 +0000680- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000681 (fixes bug #1119418).
682
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000683- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
684
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000685- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
686 exceptions that cause a function to exit.
687
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000688- The implementation of set() and frozenset() was revised to use its
689 own internal data structure. Memory consumption is reduced by 1/3
690 and there are modest speed-ups as well. The API is unchanged.
691
Tim Petersde7990b2005-07-17 23:45:23 +0000692- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
693
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000694- SF bug #1229429: PyObject_CallMethod failed to decrement some
695 reference counts in some error exit cases.
696
Tim Petersecc6e6a2005-07-10 22:30:55 +0000697- SF bug #1185883: Python's small-object memory allocator took over
698 a block managed by the platform C library whenever a realloc specified
699 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000700 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000701 portable way to copy data from the C-managed block into Python's
702 small-object space without risking a memory fault. Python's small-object
703 realloc now leaves such blocks under the control of the platform C
704 realloc.
705
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000706- SF bug #1232517: An overflow error was not detected properly when
707 attempting to convert a large float to an int in os.utime().
708
Raymond Hettinger3296e692005-06-29 23:29:56 +0000709- SF bug #1224347: hex longs now print with lowercase letters just
710 like their int counterparts.
711
Michael W. Hudson188d4362005-06-20 16:52:57 +0000712- SF bug #1163563: the original fix for bug #1010677 ("thread Module
713 Breaks PyGILState_Ensure()") broke badly in the case of multiple
714 interpreter states; back out that fix and do a better job (see
715 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
716 for a longer write-up of the problem).
717
Michael W. Hudsondf888462005-06-03 14:41:55 +0000718- SF patch #1180995: marshal now uses a binary format by default when
719 serializing floats.
720
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000721- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
722 the routines that promise to produce IEEE 754 binary representations
723 of floats now simply copy bytes around.
724
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000725- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
726 278.
727
Brett Cannonc3647ac2005-04-26 03:45:26 +0000728- patch #1109424: int, long, float, complex, and unicode now check for the
729 proper magic slot for type conversions when subclassed. Previously the
730 magic slot was ignored during conversion. Semantics now match the way
731 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000732 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000733 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000734 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000735
Barry Warsawc8d907c2005-04-19 23:43:40 +0000736- Descriptors defined in C with a PyGetSetDef structure, where the setter is
737 NULL, now raise an AttributeError when attempting to set or delete the
738 attribute. Previously a TypeError was raised, but this was inconsistent
739 with the equivalent pure-Python implementation.
740
Michael W. Hudson774479c2005-04-18 08:46:17 +0000741- It is now safe to call PyGILState_Release() before
742 PyEval_InitThreads() (note that if there is reason to believe there
743 are multiple threads around you still must call PyEval_InitThreads()
744 before using the Python API; this fix is for extension modules that
745 have no way of knowing if Python is multi-threaded yet).
746
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000747- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
748 disabled caused a crash.
749
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000750- Bug #1165306: instancemethod_new allowed the creation of a method
751 with im_class == im_self == NULL, which caused a crash when called.
752
Tim Petersecc6e6a2005-07-10 22:30:55 +0000753- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000754 fixes the crash seen in bug #1165761
755
Raymond Hettinger96229b12005-03-11 06:49:40 +0000756- Added two new builtins, any() and all().
757
Brett Cannon409d8f22005-03-05 06:47:57 +0000758- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000759 (e.g., ``class C(): pass`` is no longer a syntax error).
760 Patch #1176012 added support to the 'parser' module and 'compiler' package
761 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000762
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000763- Patch #1115086: Support PY_LONGLONG in structmember.
764
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000765- Bug #1155938: new style classes did not check that __init__() was
766 returning None.
767
Tim Petersecc6e6a2005-07-10 22:30:55 +0000768- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000769 ('\') with a specific error message.
770
Martin v. Löwisff232d72005-03-03 09:24:38 +0000771- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
772
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000773- Bug #1124295: the __name__ attribute of file objects was
774 inadvertently made inaccessible in restricted mode.
775
Tim Petersecc6e6a2005-07-10 22:30:55 +0000776- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000777 an ferror() call.
778
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000779- min() and max() now support key= arguments with the same meaning as in
780 list.sort().
781
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000782- The peephole optimizer now performs simple constant folding in expressions:
783 (2+3) --> (5).
784
Raymond Hettingera422c342005-01-11 03:03:27 +0000785- set and frozenset objects can now be marshalled. SF #1098985.
786
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000787- Bug #1077106: Poor argument checking could cause memory corruption
788 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000789
Jeremy Hyltonab630502005-02-04 18:44:06 +0000790- The parser did not complain about future statements in illegal
791 positions. It once again reports a syntax error if a future
792 statement occurs after anything other than a doc string.
793
Neil Schemenauercf52c072005-08-12 17:34:58 +0000794- Change the %s format specifier for str objects so that it returns a
795 unicode instance if the argument is not an instance of basestring and
796 calling __str__ on the argument returns a unicode instance.
797
Tim Petersf4e69282006-02-27 17:15:31 +0000798- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
799 current thread state when the auto-GIL-state machinery knows about
800 it (since the thread state is being deleted, continuing to remember it
801 can't help, but can hurt if another thread happens to get created with
802 the same thread id).
803
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000804Extension Modules
805-----------------
806
Georg Brandl43f08a82006-03-31 18:01:16 +0000807- Patch #1380952: fix SSL objects timing out on consecutive read()s

Georg Brandlbc45a3f2006-03-17 19:17:34 +0000816
Neal Norwitz10be10c2006-03-16 06:50:13 +0000817- Everything under lib-old was removed. This includes the following modules:
818 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +0000819 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +0000820 util, whatsound, whrandom, zmod
821
822- The following modules were removed: regsub, reconvert, regex, regex_syntax.
823
824- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +0000825 is deprecated. The undocumented re.engine variable no longer exists.
826
Hye-Shik Changabb903f2006-03-13 10:20:08 +0000827- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
828 SS2 (single-shift 2) escape sequences correctly.
829
Martin v. Löwis480f1bb2006-03-09 23:38:20 +0000830- The unicodedata module was updated to the 4.1 version of the Unicode
831 database. The 3.2 version is still available as unicodedata.db_3_2_0
832 for applications that require this specific version (such as IDNA).
833
Neal Norwitzb62c4332006-03-04 18:35:47 +0000834- The timing module is no longer built by default. It was deprecated
835 in PEP 4 in Python 2.0 or earlier.
836
Guido van Rossum1968ad32006-02-25 22:38:04 +0000837- Patch 1433928: Added a new type, defaultdict, to the collections module.
838 This uses the new __missing__ hook behavior added to dict (see above).
839
Georg Brandldbd83392006-02-20 09:42:33 +0000840- Bug #854823: socketmodule now builds on Sun platforms even when
841 INET_ADDRSTRLEN is not defined.
842
Georg Brandlf4f44152006-02-18 22:29:33 +0000843- Patch #1393157: os.startfile() now has an optional argument to specify
844 a "command verb" to invoke on the file.
845
Neal Norwitz082b2df2006-02-07 07:04:46 +0000846- Bug #876637, prevent stack corruption when socket descriptor
847 is larger than FD_SETSIZE.
848
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +0000849- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
850 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
851 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
852
Martin v. Löwis57a34e82006-02-04 19:12:37 +0000853- Patch #1422385: The nis module now supports access to domains other
854 than the system default domain.
855
Martin v. Löwis14694662006-02-03 12:54:16 +0000856- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
857 are reported, the limit on path name lengths is removed, and stat reports
858 WindowsError now (instead of OSError).
859
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +0000860- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

936 for large or negative values.
937
Tim Petersecc6e6a2005-07-10 22:30:55 +0000938- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000991Library
992-------
993
Nick Coghlan43832302006-04-23 17:04:07 +0000994- PEP 338: new module runpy defines a run_module function to support
995 executing modules which provide access to source code or a code object
996 via the PEP 302 import mechanisms.
997

1006 in attribute values.
1007

Georg Brandl828fdef2006-04-01 08:59:03 +00001009 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001010 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001011 module will not be built.
1012
Tim Petersc17976e2006-04-01 00:26:53 +00001013- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1014 aren't officially supported here, and trying to use them will probably
1015 raise an exception some day. But dicts have been allowed, and "mostly
1016 worked", so support for them won't go away without warning.
1017
Georg Brandl338ef7d2006-03-31 18:42:16 +00001018- Bug #1445068: getpass.getpass() can now be given an explicit stream
1019 argument to specify where to write the prompt.
1020
Georg Brandl22ec80b2006-03-31 18:25:44 +00001021- Patch #1462313, bug #1443328: the pickle modules now can handle classes

1027 key to be used for signing the uploaded code.
1028
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00001029- Queue.Queue objects now support .task_done() and .join() methods
1030 to make it easier to monitor when daemon threads have completed
1031 processing all enqueued tasks. Patch #1455676.
1032
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00001033- popen2.Popen objects now preserve the command in a .cmd attribute.

1036
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001037- email 4.0 package now integrated. This is largely the same as the email 3.0
1038 package that was included in Python 2.3, except that PEP 8 module names are
1039 now used (e.g. mail.message instead of email.Message). The MIME classes
1040 have been moved to a subpackage (e.g. email.mime.text instead of
1041 email.MIMEText). The old names are still supported for now. Several
1042 deprecated Message methods have been removed and lots of bugs have been
1043 fixed. More details can be found in the email package documentation.
1044
Walter Dörwald40108c92006-03-27 08:15:44 +00001045- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1046 (a subclass of tuple) that provides incremental decoders and encoders
1047 (a way to use stateful codecs without the stream API). Python functions
1048 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1049 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1050 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001051
Walter Dörwald067db482006-03-15 22:17:27 +00001052- Patch #1359365: Calling next() on a closed StringIO.String object raises
1053 a ValueError instead of a StopIteration now (like file and cString.String do).
1054 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1055 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001056
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001057- A regrtest option -w was added to re-run failed tests in verbose mode.

1060 interpreter to exit.
1061
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001062- The function get_count() has been added to the gc module, and gc.collect()
1063 grew an optional 'generation' argument.
1064
Martin v. Löwisfbab90e2006-03-05 13:36:04 +00001065- A library msilib to generate Windows Installer files, and a distutils

1067
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001068- PEP 343: new module contextlib.py defines decorator @contextmanager
1069 and helpful context managers nested() and closing().
1070
Martin v. Löwis415ed932006-02-27 19:56:30 +00001071- The compiler package now supports future imports after the module docstring.
1072

Martin v. Löwis3e865952006-01-24 15:51:21 +00001105 specifications, raises IOErrors when proxies for unsupported protocols
1106 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00001129 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1130 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1131 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1132 Ronald L. Rivest offered this advice for Python:
1133
1134 "The consensus of researchers in this area (at least as
1135 expressed at the NIST Hash Function Workshop 10/31/05),
1136 is that SHA-256 is a good choice for the time being, but
1137 that research should continue, and other alternatives may
1138 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001139
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001140- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandlb9256022005-08-24 18:46:39 +00001186- Patch #1062060: urllib.urlretrieve() now raises a new exception, named
1187 ContentTooShortException, when the actually downloaded size does not
1188 match the Content-Length header.
1189
Martin v. Löwis0a5d4a22005-08-24 14:55:22 +00001190- Bug #1121494: distutils.dir_utils.mkpath now accepts Unicode strings.
1191

1193 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001194 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00001195

1217 to W3C name (404 -> 'Not Found'). RFE #1216944.
1218
Georg Brandl9e43acf2005-07-04 17:16:07 +00001219- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1220 as this can cause problems with apps closing all file descriptors.

Raymond Hettingerda99d1c2005-06-21 07:43:58 +00001232- The tokenize module now detects and reports indentation errors.
1233 Bug #1224621.
1234
Raymond Hettinger68c04532005-06-10 11:05:19 +00001235- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001236 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001237 the generate_tokens() function now accepts a callable argument that
1238 terminates by raising StopIteration.
1239
Georg Brandl9166e1a2005-06-04 09:20:03 +00001240- Bug #1196315: fix weakref.WeakValueDictionary constructor.
1241

1247 to True, applications shouldn't have to fiddle with the DateTime wrapper
1248 class at all.
1249
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001250- distutils.commands.upload was added to support uploading distribution
1251 files to PyPI.
1252
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00001253- distutils.commands.register now encodes the data as UTF-8 before posting
1254 them to PyPI.
1255
Raymond Hettinger267b8682005-03-27 10:47:39 +00001256- decimal operator and comparison methods now return NotImplemented
1257 instead of raising a TypeError when interacting with other types. This
1258 allows other classes to implement __radd__ style methods and have them
1259 work as expected.
1260
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001261- Bug #1163325: Decimal infinities failed to hash. Attempting to
1262 hash a NaN raised an InvalidOperation instead of a TypeError.
1263
Tim Petersecc6e6a2005-07-10 22:30:55 +00001264- Patch #918101: Add tarfile open mode r|* for auto-detection of the

1298
Guido van Rossumd0641422005-02-03 15:01:24 +00001299- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1300 disables recursive traversal through instance attributes, which can
1301 be exploited in various ways.
1302
Tim Peterse3547fd2005-12-16 23:13:57 +00001303- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001304 flags on the HTTP listening socket.
1305
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001306- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1307 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1308
Tim Peterse3547fd2005-12-16 23:13:57 +00001309- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001310 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1311
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001312- Bug #1110478: Revert os.environ.update to do putenv again.
1313
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001314- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1315
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001316- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1317
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001318- Enhancements to the csv module:
1319
1320 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001321 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001322 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001323 + Dialect parameter parsing has been re-implemented to improve error
1324 reporting.
1325 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1326 dictates.
1327 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001328 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001329 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001330 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1331 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001332 + reader now allows \r characters to be quoted (previously it only allowed
1333 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001334 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001335 + Dialect classes passed to the module are no longer instantiated by
1336 the module before being parsed (the former validation scheme required
1337 this, but the mechanism was unreliable).
1338 + The dialect registry now contains instances of the internal
1339 C-coded dialect type, rather than references to python objects.
1340 + the internal c-coded dialect type is now immutable.
1341 + register_dialect now accepts the same keyword dialect specifications
1342 as the reader and writer, allowing the user to register dialects
1343 without first creating a dialect class.
1344 + a configurable limit to the size of parsed fields has been added -
1345 previously, an unmatched quote character could result in the entire
1346 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001347 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001348 the parser field size limit (returning the former limit). The initial
1349 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001350 + A line_num attribute has been added to the reader object, which tracks
1351 the number of lines read from the source iterator. This is not
1352 the same as the number of records returned, as records can span
1353 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001354 + reader and writer objects were not being registered with the cyclic-GC.
1355 This has been fixed.
1356
Brett Cannone6539c42005-01-08 02:43:53 +00001357- _DummyThread objects in the threading module now delete self.__block that is
1358 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1359 lock primitives tend to be limited in number and thus should not be wasted on
1360 a _DummyThread object. Fixes bug #1089632.
1361
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001362- The imghdr module now detects Exif files.
1363
Raymond Hettinger6065d322004-12-20 23:51:53 +00001364- StringIO.truncate() now correctly adjusts the size attribute.
1365 (Bug #951915).
1366
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001367- locale.py now uses an updated locale alias table (built using
1368 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1369 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001370 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001371
Raymond Hettinger3557f422004-12-07 12:02:02 +00001372- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1373
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001374- the pickle module no longer accepts the deprecated None option in the
1375 args tuple returned by __reduce__().
1376
Brett Cannon84667c02004-12-07 03:25:18 +00001377- optparse now optionally imports gettext. This allows its use in setup.py.
1378
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001379- the pickle module no longer uses the deprecated bin parameter.
1380
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001381- the shelve module no longer uses the deprecated binary parameter.
1382
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001383- the pstats module no longer uses the deprecated ignore() method.
1384
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001385- the filecmp module no longer uses the deprecated use_statcache argument.
1386
Raymond Hettinger664347b2004-12-04 21:21:53 +00001387- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1388 extended or overridden by subclasses. Formerly, the subclassed method would
1389 be ignored by the rest of the module. (Bug #1078905).
1390
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001391- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001392 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001393
Walter Dörwald36733692004-12-22 12:50:50 +00001394- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1395 once when a size argument is given. This prevents a buffer overflow in the
1396 tokenizer with very long source lines.
1397
Barry Warsaw538561e2006-01-01 21:48:54 +00001398- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1399 immediately after creating the object, without any intervening
1400 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001401
Skip Montanaro05885812005-01-16 20:48:27 +00001402- The reconvert.quote function can now emit triple-quoted strings. The
1403 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001404
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001405- ``UserString.MutableString`` now supports negative indices in
1406 ``__setitem__`` and ``__delitem__``
1407
Greg Ward40407942005-03-05 02:53:17 +00001408- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1409 correctly.
1410
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001411- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1412 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1413 character even if the user has passed a size parameter to get a proper
1414 line ending. Remove the special handling of a "\r\n" that has been split
1415 between two lines.
1416
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001417- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1418 about illegal code points. The codec now supports PEP 293 style error
1419 handlers.

Walter Dörwald78a78b02005-09-01 12:04:29 +00001421- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001422 from the input stream, so that the output is a byte string in the correct
1423 encoding instead of a unicode string.

Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001425- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1426 considering it exactly like a '*'.
1427
Walter Dörwald007f8df2005-10-09 19:42:27 +00001428- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1429 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001430
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001431- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1432
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001433- Patch #1413711: Certain patterns of differences were making difflib
1434 touch the recursion limit.
1435
Walter Dörwald58917a62006-03-31 15:26:22 +00001436- Bug #947906: An object oriented interface has been added to the calendar
1437 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001438 called as a script (e.g. via ``python -mcalendar``). Localized month and
1439 weekday names can be ouput (even if an exotic encoding is used) using
1440 special classes that use unicode.

1444
Neal Norwitz602d3392006-03-31 08:21:40 +00001445- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1446 by using -mieee gcc option.
1447

1449
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001450- Build support for Win64-AMD64 was added.
1451
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001452- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1453
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001454- Patch #881820: look for openpty and forkpty also in libbsd.
1455
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001456- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1457 The zlib module is now builtin on Windows.
1458
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001459- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1460
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001461- Bug #1189330: configure did not correctly determine the necessary
1462 value of LINKCC if python was built with GCC 4.0.
1463
Trent Mick8321b422005-07-26 02:29:21 +00001464- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1465 vulnerability in zlib 1.2.1 and 1.2.2.
1466
Brett Cannon08cd5982005-04-24 22:26:38 +00001467- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1468 flags that change binary compatibility. Changes were also made to
1469 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001470 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001471
Bob Ippolitoed233462005-03-29 13:47:59 +00001472- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1473 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1474 no longer exists). This configure patch makes things right.
1475
Martin v. Löwise2713be2005-03-08 15:03:08 +00001476- Bug #1158607: Build with --disable-unicode again.
1477
Brett Cannon46d96232005-02-16 00:07:19 +00001478- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1479 defined. Discovered as a result of not being able to build on OS X.
1480
Brett Cannon516592f2004-12-07 00:42:59 +00001481- setup.py now uses the directories specified in LDFLAGS using the -L option
1482 and in CPPFLAGS using the -I option for adding library and include
1483 directories, respectively, for compiling extension modules against. This has
1484 led to the core being compiled using the values in CPPFLAGS. It also removes
1485 the need for the special-casing of both DarwinPorts and Fink for darwin since
1486 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1487 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1488 Fink, ``-I/opt/local/include`` for DarwinPorts).
1489
Brett Cannon43802422005-02-10 20:48:03 +00001490- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1491 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1492 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1493 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001495C API
1496-----
1497
Tim Petersc9d78aa2006-03-26 23:27:58 +00001498- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1499 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1500 is obtained via the ``PyObject_`` family, it must be released via the
1501 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1502 always been officially true, but when Python's small-object allocator was
1503 introduced, an attempt was made to cater to a few extension modules
1504 discovered at the time that obtained memory via ``PyObject_New`` but
1505 released it via ``PyMem_DEL``. It's years later, and if such code still
1506 exists it will fail now (probably with segfaults, but calling wrong
1507 low-level memory management functions can yield many symptoms).
1508
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001509- Added a C API for set and frozenset objects.
1510
Raymond Hettinger66517482004-12-03 11:45:13 +00001511- Removed PyRange_New().
1512
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001513- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1514 mapping argument now. This string is used as a mapping table. Byte values
1515 greater than the length of the string and 0xFFFE are treated as undefined
1516 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00001522- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001523
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001524- Patch #1276356: New resource "urlfetch" is implemented. This enables
1525 even impatient people to run tests that require remote files.
