Hye-Shik Change6a1cb92006-06-23 21:16:18 +000015- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
16 omit a default "error" argument for NULL pointer. This allows
17 the parser to take a codec from cjkcodecs again.

20-------
21
Thomas Hellerbde08132006-06-29 18:34:15 +000022- The '_ctypes' extension module now works when Python is configured
23 with the --without-threads option.
24
Fred Drake10497c82006-06-29 02:57:48 +000025- Bug #1504333: Make sgmllib support angle brackets in quoted
26 attribute values.
27
28- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
29 sgmllib ('[' and ']' were not accepted).
30
Georg Brandl1be63af2006-06-28 20:23:25 +000031- Fix a bug in the turtle module's end_fill function.
32
Brett Cannon53ab5b72006-06-22 16:49:14 +000033- Bug #1510580: The 'warnings' module improperly required that a Warning
34 category be either a types.ClassType and a subclass of Warning. The proper
35 check is just that it is a subclass with Warning as the documentation states.
36
Georg Brandlad29e632006-06-21 17:45:17 +000037- The compiler module now correctly compiles the new try-except-finally
38 statement (bug #1509132).
39
Neal Norwitz60373cd2006-06-22 06:30:50 +000040- The wsgiref package is now installed properly on Unix.

71Core and builtins
72-----------------
73
Georg Brandla56b9152006-06-19 06:35:54 +000074- Patch #1507676: Error messages returned by invalid abstract object operations
75 (such as iterating over an integer) have been improved and now include the
76 type of the offending object to help with debugging.
77
Brett Cannonea3912b2006-06-13 21:46:41 +000078- Bug #992017: A classic class that defined a __coerce__() method that returned
79 its arguments swapped would infinitely recurse and segfault the interpreter.
80
Neal Norwitz909eb122006-06-12 02:13:21 +000081- Fix the socket tests so they can be run concurrently.
82
Neal Norwitzb9845e72006-06-12 02:11:18 +000083- Removed 5 integers from C frame objects (PyFrameObject).
84 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
85
Brett Cannon22565aa2006-06-09 22:31:23 +000086- Bug #532646: object.__call__() will continue looking for the __call__
87 attribute on objects until one without one is found. This leads to recursion
88 when you take a class and set its __call__ attribute to an instance of the
89 class. Originally fixed for classic classes, but this fix is for new-style.
90 Removes the infinite_rec_3 crasher.
91
Georg Brandl24250812006-06-09 18:45:48 +000092- The string and unicode methods startswith() and endswith() now accept
93 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
94
Brett Cannonde3b0522006-06-08 17:00:45 +000095- Buffer objects, at the C level, never used the char buffer
96 implementation even when the char buffer for the wrapped object was
97 explicitly requested (originally returned the read or write buffer).
98 Now a TypeError is raised if the char buffer is not present but is
99 requested.
100
Georg Brandlddbaa662006-06-04 21:56:52 +0000101- Patch #1346214: Statements like "if 0: suite" are now again optimized
102 away like they were in Python 2.4.
103
Georg Brandlb7c8f542006-05-27 12:30:25 +0000104- Builtin exceptions are now full-blown new-style classes instead of
105 instances pretending to be classes, which speeds up exception handling
106 by about 80% in comparison to 2.5a2.
107
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000108- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
109 Unicode 4.1.
110
Georg Brandlf4ef1162006-05-26 18:03:31 +0000111- Patch #921466: sys.path_importer_cache is now used to cache valid and
112 invalid file paths for the built-in import machinery which leads to
113 fewer open calls on startup.
114
Tim Peters696cf432006-05-24 21:10:40 +0000115- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
116 of-2 bases. The largest speedup is for inputs with about 1000 decimal
117 digits. Conversion from non-power-of-2 bases remains quadratic-time in
118 the number of input digits (it was and remains linear-time for bases
119 2, 4, 8, 16 and 32).
120
Tim Petersb713ec22006-05-23 18:45:30 +0000121- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
122 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
123 an integer close to ``sys.maxint``. This was repaired by patch
124 #1335972, which also gives a nice speedup.
125
Richard Jonescebbefc2006-05-23 18:28:17 +0000126- Patch #1337051: reduced size of frame objects.
127
128- PyErr_NewException now accepts a tuple of base classes as its
129 "base" parameter.
130
Richard Jones7c88dcc2006-05-23 10:37:38 +0000131- Patch #876206: function call speedup by retaining allocated frame
132 objects.
133
Georg Brandl7b90e162006-05-18 07:01:27 +0000134- Bug #1462152: file() now checks more thoroughly for invalid mode
135 strings and removes a possible "U" before passing the mode to the
136 C library function.
137
Neal Norwitz1004a532006-05-15 07:17:23 +0000138- Patch #1488312, Fix memory alignment problem on SPARC in unicode
139
Neal Norwitz373f0a72006-05-15 07:04:36 +0000140- Bug #1487966: Fix SystemError with conditional expression in assignment
141
Martin v. Löwis879768d2006-05-11 13:28:43 +0000142- WindowsError now has two error code attributes: errno, which carries
143 the error values from errno.h, and winerror, which carries the error
144 values from winerror.h. Previous versions put the winerror.h values
145 (from GetLastError()) into the errno attribute.
146
Martin v. Löwis77736712006-05-04 05:51:03 +0000147- Patch #1475845: Raise IndentationError for unexpected indent.
148
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000149- Patch #1479181: split open() and file() from being aliases for each other.
150
Tim Peters44bd9862006-06-01 13:49:23 +0000151- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
152 methods were always silently ignored by dictionaries when comparing keys.
153 They are now passed through (except when using the C API function
154 ``PyDict_GetItem()``, whose semantics did not change).
155
156- Bug #1456209: In some obscure cases it was possible for a class with a
157 custom ``__eq__()`` method to confuse dict internals when class instances
158 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
159 No, you don't have any code that did this ;-)

Trent Mick960a3f82006-06-28 20:30:41 +0000164- Bug #1295808: expat symbols should be namespaced in pyexpat
165
166- Patch #1462338: Upgrade pyexpat to expat 2.0.0
167
Brett Cannon6ee7d012006-06-08 16:23:04 +0000168- Change binascii.hexlify to accept a read-only buffer instead of only a char
169 buffer and actually follow its documentation.
170
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +0000171- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
172
Nick Coghlanc649ec52006-05-29 12:43:05 +0000173- Patch #1478788 (modified version): The functional extension module has
174 been renamed to _functools and a functools Python wrapper module added.
175 This provides a home for additional function related utilities that are
176 not specifically about functional programming. See PEP 309.
177
Bob Ippolito7ccc95a2006-05-23 19:11:34 +0000178- Patch #1493701: performance enhancements for struct module.
179
Georg Brandl378d5922006-05-17 14:26:50 +0000180- Patch #1490224: time.altzone is now set correctly on Cygwin.
181
Georg Brandl8d3342b2006-05-16 07:38:27 +0000182- Patch #1435422: zlib's compress and decompress objects now have a
183 copy() method.
184
Andrew MacIntyre92913322006-06-13 15:04:24 +0000185- Patch #1454481: thread stack size is now tunable at runtime for thread
186 enabled builds on Windows and systems with Posix threads support.
187
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000188- On Win32, os.listdir now supports arbitrarily-long Unicode path names
189 (up to the system limit of 32K characters).
190
191- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
192 As a result, these functions now raise WindowsError instead of OSError.
193
Tim Peters7a822da2006-05-25 21:50:17 +0000194- ``time.clock()`` on Win64 should use the high-performance Windows
195 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
196 Windows platforms).
197
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000198- Calling Tk_Init twice is refused if the first call failed as that
199 may deadlock.
200
Gregory P. Smith0459e4d2006-06-05 02:02:25 +0000201- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
202 accept it without potentially using an uninitialized pointer.
203
204- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
205 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
206 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +0000207
Gregory P. Smith372b5832006-06-05 18:48:21 +0000208- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +0000209 [pybsddb project SF patch number 1466734]
210
Gregory P. Smith372b5832006-06-05 18:48:21 +0000211- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
212 parameter is supplied. [SF pybsddb bug #1477863]
213
Gregory P. Smith3c228b12006-06-05 23:59:37 +0000214- bsddb: the __len__ method of a DB object has been fixed to return correct
215 results. It could previously incorrectly return 0 in some cases.
216 Fixes SF bug 1493322 (pybsddb bug 1184012).
217
Gregory P. Smithff7d9912006-06-08 05:17:08 +0000218- bsddb: the bsddb.dbtables Modify method now raises the proper error and
219 aborts the db transaction safely when a modifier callback fails.
220 Fixes SF python patch/bug #1408584.
221
Gregory P. Smith506f7b52006-06-15 08:52:32 +0000222- bsddb: multithreaded DB access using the simple bsddb module interface
223 now works reliably. It has been updated to use automatic BerkeleyDB
224 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
225 database calls that would previously deadlock. [SF python bug #775414]
226
Ronald Oussoren143cefb2006-06-15 08:14:18 +0000227- Patch #1446489: add support for the ZIP64 extensions to zipfile.

Martin v. Löwis6fb20aa2006-06-17 19:03:26 +0000235- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
236 functions.
237
Martin v. Löwis3798da02006-06-17 18:44:27 +0000238- Patch #812986: Update turtle output even if not tracing.
239
Martin v. Löwis92733be2006-06-17 09:25:15 +0000240- Patch #1494750: Destroy master after deleting children in
241 Tkinter.BaseWidget.
242
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +0000243- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
244
Martin v. Löwis337487e2006-06-17 09:15:14 +0000245- Patch #763580: Add name and value arguments to Tkinter variable
246 classes.
247
Georg Brandl83cc0d02006-06-14 08:50:03 +0000248- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
249 mime.types file for determining MIME types.
250
Georg Brandl2605ca82006-06-14 06:08:31 +0000251- Bug #1339007: Shelf objects now don't raise an exception in their
252 __del__ method when initialization failed.
253
Martin v. Löwisd8251432006-06-14 05:21:04 +0000254- Patch #1455898: The MBCS codec now supports the incremental mode for
255 double-byte encodings.
256
Tim Peters43898b42006-06-14 04:09:25 +0000257- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
258 guarantee that adjacent triples in the return list always describe
259 non-adjacent blocks. Previously, a pair of matching blocks could end
260 up being described by multiple adjacent triples that formed a partition
261 of the matching pair.
262
Greg Ward0e0c9f42006-06-11 16:24:11 +0000263- Bug #1498146: fix optparse to handle Unicode strings in option help,
264 description, and epilog.
265
Greg Wardd1c797e2006-06-11 14:42:41 +0000266- Bug #1366250: minor optparse documentation error.
267
Greg Ward7f547402006-06-11 00:40:49 +0000268- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
269 clarify docs.
270
Andrew M. Kuchling0873b112006-06-09 16:46:51 +0000271- The wsgiref package has been added to the standard library.
272
Nick Coghlan676725d2006-06-08 13:54:49 +0000273- The functions update_wrapper() and wraps() have been added to the functools
274 module. These make it easier to copy relevant metadata from the original
275 function when writing wrapper functions.
276
Tim Petersd6a9eef2006-06-05 01:48:21 +0000277- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
278 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +0000279
Martin v. Löwis3f767792006-06-04 19:36:28 +0000280- Patch #1359618: Speed up charmap encoder by using a trie structure
281 for lookup.
282
Tim Petersd609b1a2006-06-02 23:22:51 +0000283- The functions in the ``pprint`` module now sort dictionaries by key
284 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
285 if and only if its display required more than one line, although that
286 wasn't documented. The new behavior increases predictability; e.g.,
287 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
288
Georg Brandlfd9a4b12006-05-29 20:57:01 +0000289- Patch #1497027: try HTTP digest auth before basic auth in urllib2
290 (thanks for J. J. Lee).
291
Georg Brandl2b330372006-05-28 20:23:12 +0000292- Patch #1496206: improve urllib2 handling of passwords with respect to
293 default HTTP and HTTPS ports.
294
George Yoshidaf3c65de2006-05-28 16:39:09 +0000295- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
296
Bob Ippolito7298f272006-05-23 18:43:47 +0000297- Patch #1281707: speed up gzip.readline.
298
Georg Brandlb89316f2006-05-17 15:51:16 +0000299- Patch #1180296: Two new functions were added to the locale module:
300 format_string() to get the effect of "format % items" but locale-aware,
301 and currency() to format a monetary number with currency sign.
302
Georg Brandle3a25832006-05-17 14:56:04 +0000303- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
304 and several features added, such as speed and geometry control.
305
Georg Brandl49c8f4c2006-05-15 19:30:35 +0000306- Patch #1488881: add support for external file objects in bz2 compressed
307 tarfiles.
308
Neal Norwitz7a5fc282006-05-15 06:48:14 +0000309- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
310 stdout arguments, making it possible to redirect input and output
311 for remote debugging.
312
313- Patch #1484695: Update the tarfile module to version 0.8. This fixes
314 a couple of issues, notably handling of long file names using the
315 GNU LONGNAME extension.
316
317- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
318 new flag when ``name`` is already the name of an option flag.
319
320- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000359What's New in Python 2.5 alpha 2?
360=================================
361
362*Release date: 27-APR-2006*
363
364Core and builtins
365-----------------
366
Thomas Heller1b046642006-04-18 18:51:06 +0000367- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
368 by converting these apis from macros into exported functions again:
369
370 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
371 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
372 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
373 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
374 PyRun_String Py_CompileString
375
Martin v. Löwis45294a92006-04-18 06:24:08 +0000376- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
377
Martin v. Löwis19ab6c92006-04-16 18:55:50 +0000378- All uses of PyStructSequence_InitType have been changed to initialize
379 the type objects only once, even if the interpreter is initialized
380 multiple times.
381
Neal Norwitz61546162006-04-14 05:20:28 +0000382- Bug #1454485, array.array('u') could crash the interpreter. This was
383 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
384 to unicode when it didn't make sense. 'u#' now requires a unicode string.
385
386- Py_UNICODE is unsigned. It was always documented as unsigned, but
387 due to a bug had a signed value in previous versions.
388
Tim Peters3a5e8b12006-04-11 01:44:07 +0000389- Patch #837242: ``id()`` of any Python object always gives a positive
390 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
391 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +0000392 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +0000393 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +0000394
Tim Peters3a5e8b12006-04-11 01:44:07 +0000395 def __hash__(self):
396 return id(self) # WRONG
397
398 because a hash result must be a (short) Python int but it was always
399 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +0000400 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +0000401 was always usable as a hash value before this patch. That's no longer
402 necessarily so.
403
404- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +0000405 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +0000406 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +0000407 #1454844)
408
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000409- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
410 involving generators that have paused outside of any ``try`` or ``with``
411 blocks. (In 2.5a1, a paused generator that was part of a reference
412 cycle could not be garbage collected, regardless of whether it was
413 paused in a ``try`` or ``with`` block.)

Anthony Baxter51bcb682006-04-05 14:51:42 +0000415Extension Modules
416-----------------
417
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +0000418- Patch #1191065: Fix preprocessor problems on systems where recvfrom
419 is a macro.
420
Georg Brandlbbfe4fa2006-04-11 06:47:43 +0000421- Bug #1467952: os.listdir() now correctly raises an error if readdir()
422 fails with an error condition.
423
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +0000424- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
425
426- Bug #1117761: bsddb.*open() no longer raises an exception when using
427 the cachesize parameter.
428
429- Bug #1149413: bsddb.*open() no longer raises an exception when using
430 a temporary db (file=None) with the 'n' flag to truncate on open.
431
432- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
433 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +0000434
Armin Rigoa9017c32006-04-19 11:50:27 +0000435- Patch #1062014: AF_UNIX sockets under Linux have a special
436 abstract namespace that is now fully supported.
437
Anthony Baxter51bcb682006-04-05 14:51:42 +0000438Library
439-------
440
Tim Peters711bf302006-04-25 03:31:36 +0000441- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
442 a doctest to be skipped (the code is not run, and the expected output
443 or exception is ignored).
444
Nick Coghlanda2268f2006-04-24 04:37:15 +0000445- Fixed contextlib.nested to cope with exceptions being raised and
446 caught inside exit handlers.
447
Greg Wardab05edc2006-04-23 03:47:58 +0000448- Updated optparse module to Optik 1.5.1 (allow numeric constants in
449 hex, octal, or binary; add ``append_const`` action; keep going if
450 gettext cannot be imported; added ``OptionParser.destroy()`` method;
451 added ``epilog`` for better help generation).
452
Tim Peters21fbd572006-04-21 21:18:10 +0000453- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
454 called from a thread spawned as a side effect of importing a module.
455
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000456- The pydoc module now supports documenting packages contained in
457 .zip or .egg files.
458
459- The pkgutil module now has several new utility functions, such
460 as ``walk_packages()`` to support working with packages that are either
461 in the filesystem or zip files.
462
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000463- The mailbox module can now modify and delete messages from
464 mailboxes, in addition to simply reading them. Thanks to Gregory
465 K. Johnson for writing the code, and to the 2005 Google Summer of
466 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +0000467
Tim Petersc7605f22006-04-17 21:12:33 +0000468- The ``__del__`` method of class ``local`` in module ``_threading_local``
469 returned before accomplishing any of its intended cleanup.
470
Martin v. Löwisbd30f522006-04-17 17:08:37 +0000471- Patch #790710: Add breakpoint command lists in pdb.
472
Martin v. Löwis0db2a982006-04-16 20:55:38 +0000473- Patch #1063914: Add Tkinter.Misc.clipboard_get().
474
Martin v. Löwis4b501e62006-04-15 08:41:11 +0000475- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
476
Anthony Baxtere29002c2006-04-12 12:07:31 +0000477- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
478 Windows. Bug #1469163.
479
Phillip J. Eby47032112006-04-11 01:07:43 +0000480- The warnings, linecache, inspect, traceback, site, and doctest modules
481 were updated to work correctly with modules imported from zipfiles or
482 via other PEP 302 __loader__ objects.
483
Martin v. Löwis17de8ff2006-04-10 15:55:37 +0000484- Patch #1467770: Reduce usage of subprocess._active to processes which
485 the application hasn't waited on.
486
Martin v. Löwisb04dee92006-04-10 08:34:21 +0000487- Patch #1462222: Fix Tix.Grid.
488
Neal Norwitza31bf182006-04-09 03:35:43 +0000489- Fix exception when doing glob.glob('anything*/')
490
Skip Montanaro262fb922006-04-21 02:31:07 +0000491- The pstats.Stats class accepts an optional stream keyword argument to
492 direct output to an alternate file-like object.
493
Anthony Baxter51bcb682006-04-05 14:51:42 +0000494Build
495-----
496
Martin v. Löwis4be4e652006-04-17 19:25:49 +0000497- The Makefile now has a reindent target, which runs reindent.py on
498 the library.
499
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000500- Patch #1470875: Building Python with MS Free Compiler
501
Martin v. Löwisc90b17e2006-04-15 08:13:05 +0000502- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +0000503
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000504- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
505 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +0000506 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +0000507 CXX from --with-cxx-main, see description in README.
508
Martin v. Löwis10acfd02006-04-10 12:39:36 +0000509- Patch #1429775: Link extension modules with the shared libpython.
510
Hye-Shik Changf4795c82006-04-26 19:20:26 +0000511- Fixed a libffi build problem on MIPS systems.
512
Tim Peters8931ff12006-05-13 23:28:20 +0000513- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
514 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
515 and "%zu" for unsigned integers of type ``size_t``.
516
Anthony Baxter51bcb682006-04-05 14:51:42 +0000517Tests
518-----
519
Nick Coghlanda2268f2006-04-24 04:37:15 +0000520- test_contextlib now checks contextlib.nested can cope with exceptions
521 being raised and caught inside exit handlers.
522
Nick Coghlan27ec1a72006-04-24 04:32:47 +0000523- test_cmd_line now checks operation of the -m and -c command switches
524
Phillip J. Eby51dd7d92006-04-11 01:21:31 +0000525- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
526 it separately and by hand. It also wasn't cleaning up its changes to
527 the current Decimal context.
528
Thomas Woutersabd08882006-04-26 15:53:30 +0000529- regrtest.py now has a -M option to run tests that test the new limits of
530 containers, on 64-bit architectures. Running these tests is only sensible
531 on 64-bit machines with more than two gigabytes of memory. The argument
532 passed is the maximum amount of memory for the tests to use.

541-------------
542
Tim Petersb06d28c2006-05-12 01:57:59 +0000543- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
544
Nick Coghlanc195d8a2006-04-24 03:04:43 +0000545- PEP 343: Added Context Types section to the library reference
546 and attempted to bring other PEP 343 related documentation into
547 line with the implementation and/or python-dev discussions.
548
Tim Peters8dc73d22006-04-24 02:03:16 +0000549- Bug #1337990: clarified that ``doctest`` does not support examples
550 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000553What's New in Python 2.5 alpha 1?
554=================================
555
Anthony Baxterebed3f62006-04-03 15:03:44 +0000556*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000557
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000558Core and builtins
559-----------------
560
Nick Coghlan43832302006-04-23 17:04:07 +0000561- PEP 338: -m command line switch now delegates to runpy.run_module
562 allowing it to support modules in packages and zipfiles
563
Martin v. Löwisc661b882006-04-20 04:54:23 +0000564- On Windows, .DLL is not an accepted file name extension for
565 extension modules anymore; extensions are only found if they
566 end in .PYD.
567
Martin v. Löwisea62d252006-04-03 10:56:49 +0000568- Bug #1421664: sys.stderr.encoding is now set to the same value as
569 sys.stdout.encoding.
570
Neal Norwitz92e212f2006-04-03 04:48:37 +0000571- __import__ accepts keyword arguments.
572
Georg Brandlccadf842006-03-31 18:54:53 +0000573- Patch #1460496: round() now accepts keyword arguments.
574
Anthony Baxter262c00a2006-03-30 10:53:17 +0000575- Fixed bug #1459029 - unicode reprs were double-escaped.
576
Hye-Shik Changd478f342006-03-23 12:32:36 +0000577- Patch #1396919: The system scope threads are reenabled on FreeBSD
578 5.4 and later versions.
579
Neal Norwitze98ccf62006-03-23 05:39:47 +0000580- Bug #1115379: Compiling a Unicode string with an encoding declaration
581 now gives a SyntaxError.
582
Georg Brandlabd1ff82006-03-18 07:59:59 +0000583- Previously, Python code had no easy way to access the contents of a
584 cell object. Now, a ``cell_contents`` attribute has been added
585 (closes patch #1170323).
586
Tim Peterscf79aac2006-03-16 01:14:46 +0000587- Patch #1123430: Python's small-object allocator now returns an arena to
588 the system ``free()`` when all memory within an arena becomes unused
589 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
590 freed. Some applications will see a drop in virtual memory size now,
591 especially long-running applications that, from time to time, temporarily
592 use a large number of small objects. Note that when Python returns an
593 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +0000594 platform C library will in turn return that memory to the operating system.
595 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +0000596 appears to be effective at least on Microsoft C and gcc-based systems.
597 Thanks to Evan Jones for hard work and patience.
598
Georg Brandl533ff6f2006-03-08 18:09:27 +0000599- Patch #1434038: property() now uses the getter's docstring if there is
600 no "doc" argument given. This makes it possible to legitimately use
601 property() as a decorator to produce a read-only property.
602
Guido van Rossum9aa37ab2006-03-07 18:54:08 +0000603- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
604 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
605 of requiring an int or long in slicing and a few other contexts, enabling
606 other objects (e.g. Numeric Python's integers) to be used as slice indices.
607
Neal Norwitz995acdf2006-03-07 05:01:00 +0000608- Fixed various bugs reported by Coverity's Prevent tool.
609
Brett Cannonbf364092006-03-01 04:25:17 +0000610- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
611 new exception base class, BaseException, which has a new message attribute.
612 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
613 Raising a string exception now raises a DeprecationWarning.
614
Thomas Woutersfb609f42006-02-28 16:37:25 +0000615- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
616 explicitly relative, using 'from .module import name' to mean 'from the same
617 package as this module is in. Imports without dots still default to the
618 old relative-then-absolute, unless 'from __future__ import
619 absolute_import' is used.
620
Brett Cannona7446e32006-02-27 23:39:10 +0000621- Properly check if 'warnings' raises an exception (usually when a filter set
622 to "error" is triggered) when raising a warning for raising string
623 exceptions.
624
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000625- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +0000626 The name was removed from Include/code.h.
627
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000628- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +0000629
Guido van Rossum1968ad32006-02-25 22:38:04 +0000630- Patch 1433928:
631 - The copy module now "copies" function objects (as atomic objects).
632 - dict.__getitem__ now looks for a __missing__ hook before raising
633 KeyError.
634
Tim Peters84ef21c2006-02-28 20:39:06 +0000635- PEP 343: with statement implemented. Needs ``from __future__ import
636 with_statement``. Use of 'with' as a variable will generate a warning.
637 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +0000638 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +0000639 The following objects have __context__ methods:
640 - The built-in file type.
641 - The thread.LockType type.
642 - The following types defined by the threading module:
643 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
644 - The decimal.Context class.

Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +0000646- Fix the encodings package codec search function to only search
647 inside its own package. Fixes problem reported in patch #1433198.
648
649 Note: Codec packages should implement and register their own
650 codec search function. PEP 100 has the details.
651
Tim Peters9ea89d22006-06-04 03:26:02 +0000652- PEP 353: Using ``Py_ssize_t`` as the index type.
653
654- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
655 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
656 now allow Python to make use of memory blocks exceeding 2**32 bytes for
657 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
658 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +0000659
Neal Norwitzfc76d632006-01-10 06:03:13 +0000660- Patch #1400181, fix unicode string formatting to not use the locale.
661 This is how string objects work. u'%f' could use , instead of .
662 for the decimal point. Now both strings and unicode always use periods.
663
Neal Norwitz671b9e32006-01-09 07:07:12 +0000664- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
665 configure would break checking curses.h.
666
Georg Brandlcd4d1e82005-12-27 17:37:07 +0000667- Bug #959576: The pwd module is now builtin. This allows Python to be
668 built on UNIX platforms without $HOME set.
669
Neal Norwitzc10978f2005-12-19 06:07:16 +0000670- Bug #1072182, fix some potential problems if characters are signed.
671
Neal Norwitz5d0ad502005-12-19 04:27:42 +0000672- Bug #889500, fix line number on SyntaxWarning for global declarations.
673
Neal Norwitzdb83eb32005-12-18 05:29:30 +0000674- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
675
Neal Norwitze7214a12005-12-18 05:03:17 +0000676- Support for converting hex strings to floats no longer works.
677 This was not portable. float('0x3') now raises a ValueError.
678
Barry Warsaw2a38a862005-12-18 01:27:35 +0000679- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +0000680 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +0000681 is now displayed in interactive prompt banner.
682
Georg Brandlfa166682005-12-17 21:45:17 +0000683- Implementation of PEP 341 - Unification of try/except and try/finally.
684 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +0000685 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +0000686
Hye-Shik Chang835b2432005-12-17 04:38:31 +0000687- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
688 now encodes backslash correctly.
689
Martin v. Löwisb45b3152005-11-28 17:34:23 +0000690- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
691
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000692- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +0000693 and long longs.
694
Neal Norwitz67715f02005-11-09 06:59:35 +0000695- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +0000696 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000697 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +0000698
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000699- Replaced most Unicode charmap codecs with new ones using the
700 new Unicode translate string feature in the builtin charmap
701 codec; the codecs were created from the mapping tables available
702 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
703 encodings now include a mapping for the Apple logo)
704
Tim Peterse3547fd2005-12-16 23:13:57 +0000705- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +0000706
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000707- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000708
Martin v. Löwisbd260da2006-02-26 19:42:26 +0000709- A new AST parser implementation was completed. The abstract
710 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +0000711 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +0000712
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000713- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +0000714 The following code now raises a SyntaxError: foo(a = i for i in range(10))
715
Neal Norwitz708e51a2005-10-03 04:48:15 +0000716- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
717
Neal Norwitz11bd1192005-10-03 00:54:56 +0000718- SF Bug #887946: fix segfault when redirecting stdin from a directory.
719 Provide a warning when a directory is passed on the command line.
720
Neal Norwitz40d37812005-10-02 01:48:49 +0000721- Fix segfault with invalid coding.
722
723- SF bug #772896: unknown encoding results in MemoryError.
724
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000725- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +0000726 supported a __len__() method which evaluated to False when the iterator
727 was empty.
728
Guido van Rossum630db602005-09-20 18:49:54 +0000729- On 64-bit platforms, when __len__() returns a value that cannot be
730 represented as a C int, raise OverflowError.
731
Skip Montanarof8948ca2005-09-19 03:54:46 +0000732- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +0000733 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +0000734
Georg Brandl80bbf3f2005-09-14 19:38:29 +0000735- SF bug #893549: parsing keyword arguments was broken with a few format
736 codes.
737
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +0000738- Changes donated by Elemental Security to make it work on AIX 5.3
739 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
740 bug #105470: test_pwd fails on 64bit system (Opteron).
741
Guido van Rossum539c6622005-09-14 17:49:54 +0000742- Changes donated by Elemental Security to make it work on HP-UX 11 on
743 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
744
Georg Brandl4550b8d2005-08-26 06:43:52 +0000745- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +0000746 (fixes bug #1119418).
747
Martin v. Löwisd35edda2005-08-24 08:39:24 +0000748- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
749
Barry Warsawe2eca0b2005-08-15 18:14:19 +0000750- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
751 exceptions that cause a function to exit.
752
Raymond Hettinger9f1a6792005-07-31 01:16:36 +0000753- The implementation of set() and frozenset() was revised to use its
754 own internal data structure. Memory consumption is reduced by 1/3
755 and there are modest speed-ups as well. The API is unchanged.
756
Tim Petersde7990b2005-07-17 23:45:23 +0000757- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
758
Michael W. Hudson0edc7a02005-07-12 10:21:19 +0000759- SF bug #1229429: PyObject_CallMethod failed to decrement some
760 reference counts in some error exit cases.
761
Tim Petersecc6e6a2005-07-10 22:30:55 +0000762- SF bug #1185883: Python's small-object memory allocator took over
763 a block managed by the platform C library whenever a realloc specified
764 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +0000765 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +0000766 portable way to copy data from the C-managed block into Python's
767 small-object space without risking a memory fault. Python's small-object
768 realloc now leaves such blocks under the control of the platform C
769 realloc.
770
Michael W. Hudsonb8963812005-07-05 15:21:58 +0000771- SF bug #1232517: An overflow error was not detected properly when
772 attempting to convert a large float to an int in os.utime().
773
Raymond Hettinger3296e692005-06-29 23:29:56 +0000774- SF bug #1224347: hex longs now print with lowercase letters just
775 like their int counterparts.
776
Michael W. Hudson188d4362005-06-20 16:52:57 +0000777- SF bug #1163563: the original fix for bug #1010677 ("thread Module
778 Breaks PyGILState_Ensure()") broke badly in the case of multiple
779 interpreter states; back out that fix and do a better job (see
780 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
781 for a longer write-up of the problem).
782
Michael W. Hudsondf888462005-06-03 14:41:55 +0000783- SF patch #1180995: marshal now uses a binary format by default when
784 serializing floats.
785
Michael W. Hudsonda85a902005-06-01 11:34:22 +0000786- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
787 the routines that promise to produce IEEE 754 binary representations
788 of floats now simply copy bytes around.
789
Skip Montanarobbf12ba2005-05-20 03:07:06 +0000790- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
791 278.
792
Brett Cannonc3647ac2005-04-26 03:45:26 +0000793- patch #1109424: int, long, float, complex, and unicode now check for the
794 proper magic slot for type conversions when subclassed. Previously the
795 magic slot was ignored during conversion. Semantics now match the way
796 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +0000797 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +0000798 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +0000799 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +0000800
Barry Warsawc8d907c2005-04-19 23:43:40 +0000801- Descriptors defined in C with a PyGetSetDef structure, where the setter is
802 NULL, now raise an AttributeError when attempting to set or delete the
803 attribute. Previously a TypeError was raised, but this was inconsistent
804 with the equivalent pure-Python implementation.
805
Michael W. Hudson774479c2005-04-18 08:46:17 +0000806- It is now safe to call PyGILState_Release() before
807 PyEval_InitThreads() (note that if there is reason to believe there
808 are multiple threads around you still must call PyEval_InitThreads()
809 before using the Python API; this fix is for extension modules that
810 have no way of knowing if Python is multi-threaded yet).
811
Michael W. Hudsone3afc592005-04-07 10:11:19 +0000812- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
813 disabled caused a crash.
814
Michael W. Hudsonb330adf2005-03-31 09:35:44 +0000815- Bug #1165306: instancemethod_new allowed the creation of a method
816 with im_class == im_self == NULL, which caused a crash when called.
817
Tim Petersecc6e6a2005-07-10 22:30:55 +0000818- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +0000819 fixes the crash seen in bug #1165761
820
Raymond Hettinger96229b12005-03-11 06:49:40 +0000821- Added two new builtins, any() and all().
822
Brett Cannon409d8f22005-03-05 06:47:57 +0000823- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +0000824 (e.g., ``class C(): pass`` is no longer a syntax error).
825 Patch #1176012 added support to the 'parser' module and 'compiler' package
826 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +0000827
Martin v. Löwis96d743e2005-03-03 23:00:26 +0000828- Patch #1115086: Support PY_LONGLONG in structmember.
829
Raymond Hettingerb67cc802005-03-03 16:45:19 +0000830- Bug #1155938: new style classes did not check that __init__() was
831 returning None.
832
Tim Petersecc6e6a2005-07-10 22:30:55 +0000833- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +0000834 ('\') with a specific error message.
835
Martin v. Löwisff232d72005-03-03 09:24:38 +0000836- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
837
Michael W. Hudson8e1afab2005-02-17 14:55:21 +0000838- Bug #1124295: the __name__ attribute of file objects was
839 inadvertently made inaccessible in restricted mode.
840
Tim Petersecc6e6a2005-07-10 22:30:55 +0000841- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +0000842 an ferror() call.
843
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +0000844- min() and max() now support key= arguments with the same meaning as in
845 list.sort().
846
Raymond Hettingerc34f8672005-01-02 06:17:33 +0000847- The peephole optimizer now performs simple constant folding in expressions:
848 (2+3) --> (5).
849
Raymond Hettingera422c342005-01-11 03:03:27 +0000850- set and frozenset objects can now be marshalled. SF #1098985.
851
Michael W. Hudsonfaa76482005-01-31 17:09:25 +0000852- Bug #1077106: Poor argument checking could cause memory corruption
853 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000854
Jeremy Hyltonab630502005-02-04 18:44:06 +0000855- The parser did not complain about future statements in illegal
856 positions. It once again reports a syntax error if a future
857 statement occurs after anything other than a doc string.
858
Neil Schemenauercf52c072005-08-12 17:34:58 +0000859- Change the %s format specifier for str objects so that it returns a
860 unicode instance if the argument is not an instance of basestring and
861 calling __str__ on the argument returns a unicode instance.
862
Tim Petersf4e69282006-02-27 17:15:31 +0000863- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
864 current thread state when the auto-GIL-state machinery knows about
865 it (since the thread state is being deleted, continuing to remember it
866 can't help, but can hurt if another thread happens to get created with
867 the same thread id).
868
Raymond Hettinger4901a1f2004-12-02 08:59:14 +0000869Extension Modules
870-----------------
871
Georg Brandl43f08a82006-03-31 18:01:16 +0000872- Patch #1380952: fix SSL objects timing out on consecutive read()s
873
Neal Norwitz05a45592006-03-20 06:30:08 +0000874- Patch #1309579: wait3 and wait4 were added to the posix module.
875
Anthony Baxterfa869072006-03-20 05:21:58 +0000876- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
877 In addition, the existing ulaw code was updated.
878
Georg Brandlbc45a3f2006-03-17 19:17:34 +0000879- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +0000880 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +0000881
Neal Norwitz10be10c2006-03-16 06:50:13 +0000882- Everything under lib-old was removed. This includes the following modules:
883 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +0000884 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +0000885 util, whatsound, whrandom, zmod
886
887- The following modules were removed: regsub, reconvert, regex, regex_syntax.
888
889- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +0000890 is deprecated. The undocumented re.engine variable no longer exists.
891
Hye-Shik Changabb903f2006-03-13 10:20:08 +0000892- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
893 SS2 (single-shift 2) escape sequences correctly.
894
Martin v. Löwis480f1bb2006-03-09 23:38:20 +0000895- The unicodedata module was updated to the 4.1 version of the Unicode
896 database. The 3.2 version is still available as unicodedata.db_3_2_0
897 for applications that require this specific version (such as IDNA).
898
Neal Norwitzb62c4332006-03-04 18:35:47 +0000899- The timing module is no longer built by default. It was deprecated
900 in PEP 4 in Python 2.0 or earlier.
901
Guido van Rossum1968ad32006-02-25 22:38:04 +0000902- Patch 1433928: Added a new type, defaultdict, to the collections module.
903 This uses the new __missing__ hook behavior added to dict (see above).
904
Georg Brandldbd83392006-02-20 09:42:33 +0000905- Bug #854823: socketmodule now builds on Sun platforms even when
906 INET_ADDRSTRLEN is not defined.
907
Georg Brandlf4f44152006-02-18 22:29:33 +0000908- Patch #1393157: os.startfile() now has an optional argument to specify

1057-------
1058
Nick Coghlan43832302006-04-23 17:04:07 +00001059- PEP 338: new module runpy defines a run_module function to support
1060 executing modules which provide access to source code or a code object
1061 via the PEP 302 import mechanisms.
1062

1071 in attribute values.
1072
Anthony Baxterc51ee692006-04-01 00:57:31 +00001073- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001074 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001075 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001076 module will not be built.
1077
Tim Petersc17976e2006-04-01 00:26:53 +00001078- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1079 aren't officially supported here, and trying to use them will probably
1080 raise an exception some day. But dicts have been allowed, and "mostly
1081 worked", so support for them won't go away without warning.
1082
Georg Brandl338ef7d2006-03-31 18:42:16 +00001083- Bug #1445068: getpass.getpass() can now be given an explicit stream

1101
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001102- email 4.0 package now integrated. This is largely the same as the email 3.0
1103 package that was included in Python 2.3, except that PEP 8 module names are
1104 now used (e.g. mail.message instead of email.Message). The MIME classes
1105 have been moved to a subpackage (e.g. email.mime.text instead of
1106 email.MIMEText). The old names are still supported for now. Several
1107 deprecated Message methods have been removed and lots of bugs have been
1108 fixed. More details can be found in the email package documentation.
1109
Walter Dörwald40108c92006-03-27 08:15:44 +00001110- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1111 (a subclass of tuple) that provides incremental decoders and encoders
1112 (a way to use stateful codecs without the stream API). Python functions
1113 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1114 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1115 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00001116
Walter Dörwald067db482006-03-15 22:17:27 +00001117- Patch #1359365: Calling next() on a closed StringIO.String object raises
1118 a ValueError instead of a StopIteration now (like file and cString.String do).
1119 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1120 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00001121
Martin v. Löwis04824ce2006-03-10 21:26:16 +00001122- A regrtest option -w was added to re-run failed tests in verbose mode.

Georg Brandl4edd9892006-01-13 16:59:46 +00001182- Bug #1403410: The warnings module now doesn't get confused
1183 when it can't find out the module name it generates a warning for.
Georg Brandlb709c2c2006-01-20 09:07:35 +00001184
Martin v. Löwis412ed3b2006-01-08 10:45:39 +00001185- Patch #1177307: Added a new codec utf_8_sig for UTF-8 with a BOM signature.
1186

1188
Neal Norwitz338e7862005-12-23 21:27:46 +00001189- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
1190 LoadError as documented, instead of IOError. For compatibility,
1191 LoadError subclasses IOError.
1192
Brett Cannon3cbd0382005-12-16 22:49:23 +00001193- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00001194 SHA1, 224, 256, 384, and 512. Note that recent developments make the
1195 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
1196 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
1197 Ronald L. Rivest offered this advice for Python:
1198
1199 "The consensus of researchers in this area (at least as
1200 expressed at the NIST Hash Function Workshop 10/31/05),
1201 is that SHA-256 is a good choice for the time being, but
1202 that research should continue, and other alternatives may
1203 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00001204
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00001205- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandlb9256022005-08-24 18:46:39 +00001251- Patch #1062060: urllib.urlretrieve() now raises a new exception, named
1252 ContentTooShortException, when the actually downloaded size does not
1253 match the Content-Length header.
1254

1258 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00001259 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00001260

1282 to W3C name (404 -> 'Not Found'). RFE #1216944.
1283
Georg Brandl9e43acf2005-07-04 17:16:07 +00001284- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
1285 as this can cause problems with apps closing all file descriptors.

Raymond Hettingerda99d1c2005-06-21 07:43:58 +00001297- The tokenize module now detects and reports indentation errors.
1298 Bug #1224621.
1299
Raymond Hettinger68c04532005-06-10 11:05:19 +00001300- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001301 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00001302 the generate_tokens() function now accepts a callable argument that
1303 terminates by raising StopIteration.
1304
Georg Brandl9166e1a2005-06-04 09:20:03 +00001305- Bug #1196315: fix weakref.WeakValueDictionary constructor.

1309
Skip Montanaro174dd222005-05-14 20:54:16 +00001310- Patch #1120353: The xmlrpclib module provides better, more transparent,
1311 support for datetime.{datetime,date,time} objects. With use_datetime set
1312 to True, applications shouldn't have to fiddle with the DateTime wrapper
1313 class at all.
1314
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00001315- distutils.commands.upload was added to support uploading distribution

1319 them to PyPI.
1320
Raymond Hettinger267b8682005-03-27 10:47:39 +00001321- decimal operator and comparison methods now return NotImplemented
1322 instead of raising a TypeError when interacting with other types. This
1323 allows other classes to implement __radd__ style methods and have them
1324 work as expected.
1325
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00001326- Bug #1163325: Decimal infinities failed to hash. Attempting to
1327 hash a NaN raised an InvalidOperation instead of a TypeError.
1328
Tim Petersecc6e6a2005-07-10 22:30:55 +00001329- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00001330 stream compression; add, for symmetry reasons, r:* as a synonym of r.
1331

1342
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00001343- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
1344

1363
Guido van Rossumd0641422005-02-03 15:01:24 +00001364- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
1365 disables recursive traversal through instance attributes, which can
1366 be exploited in various ways.
1367
Tim Peterse3547fd2005-12-16 23:13:57 +00001368- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00001369 flags on the HTTP listening socket.
1370
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00001371- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
1372 Fixed by reading the HTTP body in chunks instead of one big socket.read().
1373
Tim Peterse3547fd2005-12-16 23:13:57 +00001374- Patches #893642, #1039083: add allow_none, encoding arguments to constructors of
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00001375 SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
1376
Martin v. Löwis1d11de62005-01-29 13:29:23 +00001377- Bug #1110478: Revert os.environ.update to do putenv again.
1378
Thomas Hellerd6c6e222005-01-20 19:20:16 +00001379- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
1380
Martin v. Löwis22b457e2005-01-16 08:40:58 +00001381- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
1382
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001383- Enhancements to the csv module:
1384
1385 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00001386 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00001387 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001388 + Dialect parameter parsing has been re-implemented to improve error
1389 reporting.
1390 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
1391 dictates.
1392 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001393 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00001394 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00001395 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
1396 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00001397 + reader now allows \r characters to be quoted (previously it only allowed
1398 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00001399 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001400 + Dialect classes passed to the module are no longer instantiated by
1401 the module before being parsed (the former validation scheme required
1402 this, but the mechanism was unreliable).
1403 + The dialect registry now contains instances of the internal
1404 C-coded dialect type, rather than references to python objects.
1405 + the internal c-coded dialect type is now immutable.
1406 + register_dialect now accepts the same keyword dialect specifications
1407 as the reader and writer, allowing the user to register dialects
1408 without first creating a dialect class.
1409 + a configurable limit to the size of parsed fields has been added -
1410 previously, an unmatched quote character could result in the entire
1411 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00001412 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001413 the parser field size limit (returning the former limit). The initial
1414 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00001415 + A line_num attribute has been added to the reader object, which tracks
1416 the number of lines read from the source iterator. This is not
1417 the same as the number of records returned, as records can span
1418 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00001419 + reader and writer objects were not being registered with the cyclic-GC.
1420 This has been fixed.
1421
Brett Cannone6539c42005-01-08 02:43:53 +00001422- _DummyThread objects in the threading module now delete self.__block that is
1423 inherited from _Thread since it uses up a lock allocated by 'thread'. The
1424 lock primitives tend to be limited in number and thus should not be wasted on
1425 a _DummyThread object. Fixes bug #1089632.
1426
Raymond Hettinger97db05d2005-01-07 08:15:41 +00001427- The imghdr module now detects Exif files.
1428
Raymond Hettinger6065d322004-12-20 23:51:53 +00001429- StringIO.truncate() now correctly adjusts the size attribute.
1430 (Bug #951915).
1431
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001432- locale.py now uses an updated locale alias table (built using
1433 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
1434 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00001435 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00001436
Raymond Hettinger3557f422004-12-07 12:02:02 +00001437- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
1438
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00001439- the pickle module no longer accepts the deprecated None option in the
1440 args tuple returned by __reduce__().
1441
Brett Cannon84667c02004-12-07 03:25:18 +00001442- optparse now optionally imports gettext. This allows its use in setup.py.
1443
Raymond Hettinger3489cad2004-12-05 05:20:42 +00001444- the pickle module no longer uses the deprecated bin parameter.
1445
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00001446- the shelve module no longer uses the deprecated binary parameter.
1447
Raymond Hettinger6c92d762004-12-05 03:28:00 +00001448- the pstats module no longer uses the deprecated ignore() method.
1449
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00001450- the filecmp module no longer uses the deprecated use_statcache argument.
1451
Raymond Hettinger664347b2004-12-04 21:21:53 +00001452- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
1453 extended or overridden by subclasses. Formerly, the subclassed method would
1454 be ignored by the rest of the module. (Bug #1078905).
1455
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001456- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001457 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001458
Walter Dörwald36733692004-12-22 12:50:50 +00001459- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
1460 once when a size argument is given. This prevents a buffer overflow in the
1461 tokenizer with very long source lines.
1462
Barry Warsaw538561e2006-01-01 21:48:54 +00001463- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
1464 immediately after creating the object, without any intervening
1465 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00001466
Skip Montanaro05885812005-01-16 20:48:27 +00001467- The reconvert.quote function can now emit triple-quoted strings. The
1468 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001469
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00001470- ``UserString.MutableString`` now supports negative indices in
1471 ``__setitem__`` and ``__delitem__``
1472
Greg Ward40407942005-03-05 02:53:17 +00001473- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
1474 correctly.
1475
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00001476- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
1477 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
1478 character even if the user has passed a size parameter to get a proper
1479 line ending. Remove the special handling of a "\r\n" that has been split
1480 between two lines.
1481
Walter Dörwalda47d1c02005-08-30 10:23:14 +00001482- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
1483 about illegal code points. The codec now supports PEP 293 style error
1484 handlers.
1485
Walter Dörwald78a78b02005-09-01 12:04:29 +00001486- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00001487 from the input stream, so that the output is a byte string in the correct
1488 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00001489
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001490- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
1491 considering it exactly like a '*'.
1492
Walter Dörwald007f8df2005-10-09 19:42:27 +00001493- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
1494 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00001495
Walter Dörwald09f0dd52005-11-21 19:10:07 +00001496- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
1497
Gustavo Niemeyer548148812006-01-31 18:34:13 +00001498- Patch #1413711: Certain patterns of differences were making difflib
1499 touch the recursion limit.
1500
Walter Dörwald58917a62006-03-31 15:26:22 +00001501- Bug #947906: An object oriented interface has been added to the calendar
1502 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00001503 called as a script (e.g. via ``python -mcalendar``). Localized month and
1504 weekday names can be ouput (even if an exotic encoding is used) using
1505 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00001506
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001507Build
1508-----
1509
Neal Norwitz602d3392006-03-31 08:21:40 +00001510- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
1511 by using -mieee gcc option.
1512
Martin v. Löwis86d66262006-02-17 08:40:11 +00001513- Patch #1432345: Make python compile on DragonFly.
1514
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00001515- Build support for Win64-AMD64 was added.
1516
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00001517- Patch #1428494: Prefer linking against ncursesw over ncurses library.
1518
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00001519- Patch #881820: look for openpty and forkpty also in libbsd.
1520
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00001521- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
1522 The zlib module is now builtin on Windows.
1523
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00001524- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
1525
Martin v. Löwis147fbe52005-08-07 21:09:30 +00001526- Bug #1189330: configure did not correctly determine the necessary
1527 value of LINKCC if python was built with GCC 4.0.
1528
Trent Mick8321b422005-07-26 02:29:21 +00001529- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
1530 vulnerability in zlib 1.2.1 and 1.2.2.
1531
Brett Cannon08cd5982005-04-24 22:26:38 +00001532- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
1533 flags that change binary compatibility. Changes were also made to
1534 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00001535 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00001536
Bob Ippolitoed233462005-03-29 13:47:59 +00001537- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
1538 and linking has changed (prebinding is now deprecated, and libcc_dynamic
1539 no longer exists). This configure patch makes things right.
1540
Martin v. Löwise2713be2005-03-08 15:03:08 +00001541- Bug #1158607: Build with --disable-unicode again.
1542
Brett Cannon46d96232005-02-16 00:07:19 +00001543- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
1544 defined. Discovered as a result of not being able to build on OS X.
1545
Brett Cannon516592f2004-12-07 00:42:59 +00001546- setup.py now uses the directories specified in LDFLAGS using the -L option
1547 and in CPPFLAGS using the -I option for adding library and include
1548 directories, respectively, for compiling extension modules against. This has
1549 led to the core being compiled using the values in CPPFLAGS. It also removes
1550 the need for the special-casing of both DarwinPorts and Fink for darwin since
1551 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
1552 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
1553 Fink, ``-I/opt/local/include`` for DarwinPorts).
1554
Brett Cannon43802422005-02-10 20:48:03 +00001555- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
1556 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
1557 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
1558 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001560C API
1561-----
1562
Tim Petersc9d78aa2006-03-26 23:27:58 +00001563- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
1564 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
1565 is obtained via the ``PyObject_`` family, it must be released via the
1566 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
1567 always been officially true, but when Python's small-object allocator was
1568 introduced, an attempt was made to cater to a few extension modules
1569 discovered at the time that obtained memory via ``PyObject_New`` but
1570 released it via ``PyMem_DEL``. It's years later, and if such code still
1571 exists it will fail now (probably with segfaults, but calling wrong
1572 low-level memory management functions can yield many symptoms).
1573
Raymond Hettingerbeb31012005-08-16 03:47:52 +00001574- Added a C API for set and frozenset objects.
1575
Raymond Hettinger66517482004-12-03 11:45:13 +00001576- Removed PyRange_New().
1577
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00001578- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
1579 mapping argument now. This string is used as a mapping table. Byte values
1580 greater than the length of the string and 0xFFFE are treated as undefined
1581 mappings.

1586
Martin v. Löwis4d394df2005-01-23 09:19:22 +00001587- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001588
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00001589- Patch #1276356: New resource "urlfetch" is implemented. This enables
1590 even impatient people to run tests that require remote files.
