583 the IndexError caused by passing in an invalid breakpoint number.
584

586 be equal to calling getsockname() on the server's socket. Fixed by patch
587 #1545011.
588
Thomas Heller8bf469d2007-03-09 20:48:57 +0000589- Bug #1651235: When a tuple was passed to a ctypes function call,
590 Python would crash instead of raising an error.
Georg Brandl1f215782006-09-24 10:36:08 +0000591

598
Georg Brandld59ea472007-03-08 18:37:35 +0000599- unittest now verifies more of its assumptions. In particular, TestCase
600 and TestSuite subclasses (not instances) are no longer accepted in
601 TestSuite.addTest(). This should cause no incompatibility since it
602 never made sense with ordinary subclasses -- the failure just occurred
603 later, with a more cumbersome exception.

954=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000955
Anthony Baxterb4096662006-08-16 03:42:26 +0000956*Release date: 17-AUG-2006*
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000957
958Core and builtins
959-----------------
960
Neal Norwitz24b6f202006-09-05 04:43:56 +0000961- Fix infinite recursion when subclassing long and overriding __hash__.
962
963- Fix concatenation (+=) of long strings.
964
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000965- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000966 compared equal or unequal to a string and a UnicodeDecodeError
967 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000968
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000969 Instead, the equal (==) and unequal (!=) comparison operators will
970 now issue a UnicodeWarning and interpret the two objects as
971 unequal. The UnicodeWarning can be filtered as desired using
972 the warning framework, e.g. silenced completely, turned into an
973 exception, logged, etc.
974
975 Note that compare operators other than equal and unequal will still
976 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000977
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000978- Fix segfault when doing string formatting on subclasses of long.
979
980- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
981 with new-style classes.
982
983- Fix bug related to __len__ functions returning negative values with
984 classic classes.
985
986- Patch #1538606, Fix __index__() clipping. There were some problems
987 discovered with the API and how integers that didn't fit into Py_ssize_t
988 were handled. This patch attempts to provide enough alternatives
989 to effectively use __index__.
990
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000991- Bug #1536021: __hash__ may now return long int; the final hash
992 value is obtained by invoking hash on the long int.
993
Thomas Hellerab1049c2006-08-08 17:37:00 +0000994- Bug #1536786: buffer comparison could emit a RuntimeWarning.
995
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000996- Bug #1535165: fixed a segfault in input() and raw_input() when
997 sys.stdin is closed.
998
Thomas Heller74d36f02006-08-04 18:17:40 +0000999- On Windows, the PyErr_Warn function is now exported from
1000 the Python dll again.
1001
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001002- Bug #1191458: tracing over for loops now produces a line event
1003 on each iteration. Fixing this problem required changing the .pyc
1004 magic number. This means that .pyc files generated before 2.5c1
1005 will be regenerated.
1006
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001007- Bug #1333982: string/number constants were inappropriately stored
1008 in the byte code and co_consts even if they were not used, ie
1009 immediately popped off the stack.
1010
Georg Brandle9462c72006-08-04 18:03:37 +00001011- Fixed a reference-counting problem in property().
1012

1014Library
1015-------
1016
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001017- Fix a bug in the ``compiler`` package that caused invalid code to be
1018 generated for generator expressions.
1019
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001020- The distutils version has been changed to 2.5.0. The change to
1021 keep it programmatically in sync with the Python version running
1022 the code (introduced in 2.5b3) has been reverted. It will continue
1023 to be maintained manually as static string literal.
1024
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001025- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001026 and this cannot be converted to the required C type, an exception is
1027 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001028 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001029
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001030- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001031 an exception.
1032
Tim Peterscbdd3502006-09-05 01:47:53 +00001033- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001034 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001035 workarounds for clocks with low resolution, to stop the code yielding
1036 duplicate UUIDs.
1037
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001038- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1039 before raising SystemExit, allowing IDLE to honor quit() and exit().
1040
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001041- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1042
Georg Brandl7a1af772006-08-14 21:55:28 +00001043- Patch #1536071: trace.py should now find the full module name of a
1044 file correctly even on Windows.
1045
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001046- logging's atexit hook now runs even if the rest of the module has
1047 already been cleaned up.
1048
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001049- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001050
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001051- Bug #1531405, format_exception no longer raises an exception if
1052 str(exception) raised an exception.
1053
Neil Schemenauer06ded092006-08-04 16:20:30 +00001054- Fix a bug in the ``compiler`` package that caused invalid code to be
1055 generated for nested functions.

1066 raises the correct exceptions.
1067
Thomas Heller1ce433e2006-08-14 16:20:04 +00001068- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1069 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1070
Thomas Heller86720042006-08-14 11:17:48 +00001071- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1072 uses the _as_parameter_ attribute when objects are passed to foreign
1073 function calls. The ctypes version number was changed to 1.0.1.
1074
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001075- Bug #1530559, struct.pack raises TypeError where it used to convert.
1076 Passing float arguments to struct.pack when integers are expected
1077 now triggers a DeprecationWarning.
1078

Fred Drake53912162006-07-29 13:22:49 +00001122What's New in Python 2.5 beta 3?
1123================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001124
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001125*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001126
1127Core and builtins
1128-----------------
1129
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001130- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001131 returned a long (see PEP 353).
1132
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001133- Bug #1515471: string.replace() accepts character buffers again.
1134
Neal Norwitz07aadb12006-07-30 06:55:48 +00001135- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1136 This provides the proper warning for struct.pack().
1137 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1138
Neal Norwitz0d62a062006-07-30 06:53:31 +00001139- Patch #1531113: Fix augmented assignment with yield expressions.
1140 Also fix a SystemError when trying to assign to yield expressions.
1141
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001142- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1143 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1144 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1145 excessive filesystem operations during imports.
1146
Tim Petersbc24eee2006-07-27 01:14:53 +00001147- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1148 operations on signed longs that are formally undefined by C.
1149 Unfortunately, at least one compiler now cares about that, so complicated
1150 the code to make that compiler happy again.
1151
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001152- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1153
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001154- Patch #1232023: Stop including current directory in search
1155 path on Windows.
1156
Neal Norwitze1fdb322006-07-21 05:32:28 +00001157- Fix some potential crashes found with failmalloc.
1158
Neal Norwitze7563102006-07-17 01:00:16 +00001159- Fix warnings reported by Klocwork's static analysis tool.
1160
Neal Norwitz84be93b2006-07-16 01:50:38 +00001161- Bug #1512814, Fix incorrect lineno's when code within a function
1162 had more than 255 blank lines.
1163
Georg Brandl9dceedb2006-07-12 15:31:17 +00001164- Patch #1521179: Python now accepts the standard options ``--help`` and
1165 ``--version`` as well as ``/?`` on Windows.
1166
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001167- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001168 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001169 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001170
Tim Peters112aad32006-07-19 00:03:19 +00001171- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001172 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001173 new ``sys._current_frames()`` returns a dictionary with one entry,
1174 mapping the faux "thread id" 0 to the current frame.
1175

1180-------
1181
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001182- Correction of patch #1455898: In the mbcs decoder, set final=False
1183 for stream decoder, but final=True for the decode function.
1184
Georg Brandl07fec3a2006-08-01 18:49:24 +00001185- os.urandom no longer masks unrelated exceptions like SystemExit or
1186 KeyboardInterrupt.
1187
Tim Peters4643c2f2006-08-10 22:45:34 +00001188- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001189 shutil.copytree on Windows
1190
Georg Brandle34ac7c2006-07-30 11:07:23 +00001191- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1192 refers to file descriptors, not file objects.
1193
Tim Peterscbdd3502006-09-05 01:47:53 +00001194- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001195 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001196 #1513611, and probably others.
1197
Georg Brandledd9b0d2006-07-29 09:33:26 +00001198- Bug #1441397: The compiler module now recognizes module and function
1199 docstrings correctly as it did in Python 2.4.
1200
Tim Peters6f681472006-07-27 23:44:37 +00001201- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1202 lost that tests are sorted by name before being run. This rarely
1203 matters for well-written tests, but can create baffling symptoms if
1204 side effects from one test to the next affect outcomes. ``DocTestFinder``
1205 has been changed to sort the list of tests it returns.
1206
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001207- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001208 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001209
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001210- Bug #978833: Really close underlying socket in _socketobject.close.
1211
Georg Brandldb232dc2006-08-20 13:15:43 +00001212- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1213 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001214
Georg Brandlcf0c1722006-07-26 07:23:32 +00001215- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1216 to recursive calls and call it with the failing package name.
1217
Martin v. Löwis0b483032006-07-25 09:53:12 +00001218- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1219
Georg Brandlc13c34c2006-07-24 14:09:56 +00001220- Patch #1515343: Fix printing of deprecated string exceptions with a
1221 value in the traceback module.
1222
Greg Ward48fae7a2006-07-23 16:05:51 +00001223- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1224
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001225- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1226
Brett Cannoncaebe222006-07-18 04:41:36 +00001227- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1228 argument tuple. For arguments where zero is illegal, the value is forced to
1229 the minimum value that is correct. This is to support an undocumented but
1230 common way people used to fill in inconsequential information in the time
1231 tuple pre-2.4.
1232
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001233- Patch #1220874: Update the binhex module for Mach-O.
1234
Barry Warsawb110bad2006-07-21 14:51:07 +00001235- The email package has improved RFC 2231 support, specifically for
1236 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1237 (name*0=<blah>) parameter continuations. This may change the types of
1238 values returned from email.message.Message.get_param() and friends.
1239 Specifically in some cases where non-encoded continuations were used,
1240 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1241 will just return the string (since non-encoded continuations don't have
1242 charset and language parts).
1243
1244 Also, whereas % values were decoded in all parameter continuations, they are
1245 now only decoded in encoded parameter parts.
1246
Ronald Oussoren3075e162006-07-25 20:28:55 +00001247- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1248
1249- Bug #1517996: IDLE now longer shows the default Tk menu when a
1250 path browser, class browser or debugger is the frontmost window on MacOS X
1251
Barry Warsaw00decd72006-07-27 23:43:15 +00001252- Patch #1520294: Support for getset and member descriptors in types.py,
1253 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1254 of an object against these built-in types and more importantly, for getting
1255 their docstrings printed in the interactive interpreter's help() function.

1259-----------------
1260
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001261- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1262 a socket operation on a socket with a timeout, the exception will be
1263 caught correctly. Previously, the exception was not caught.
1264
Thomas Heller1393d6a2006-07-28 21:43:20 +00001265- Patch #1529514: The _ctypes extension is now compiled on more
1266 openbsd target platforms.
1267
Tim Peters9cab5932006-07-28 00:30:00 +00001268- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1269 a memory leak, affecting pickles and deep copies.
1270
Tim Petersbc24eee2006-07-27 01:14:53 +00001271- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001272 Paul Eggert.
1273
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001274- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1275
Thomas Hellerce049a02006-07-14 17:51:14 +00001276- Patch #1521817: Index range checking on ctypes arrays containing
1277 exactly one element enabled again. This allows iterating over these
1278 arrays, without the need to check the array size before.
1279
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001280- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001281 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001282 /dev/null in certain cases; this is now fixed.
1283
Thomas Heller47d7a062006-07-12 08:43:47 +00001284- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1285 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001286
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001287- Because of a misspelled preprocessor symbol, ctypes was always
1288 compiled without thread support; this is now fixed.
1289
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001290- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1291 methods now allow their database parameter to be None as the
1292 sleepycat API allows.
1293
Matt Flemingec926502006-07-28 11:27:27 +00001294- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1295 bluetooth API compared with Linux and FreeBSD.
1296
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001297Tests
1298-----
1299
1300- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1301 how long the test file should take to play. Now accepts taking 2.93 secs
1302 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1303
Georg Brandl4793aa32006-07-28 18:31:39 +00001304- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1305 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1306 run via ``regrtest.py``. Now they do.

1311- Bug #1439538: Drop usage of test -e in configure as it is not portable.
1312
Ronald Oussoren26cad082006-08-01 21:00:57 +00001313Mac
1314---
1315
1316- PythonLauncher now works correctly when the path to the script contains
1317 characters that are treated specially by the shell (such as quotes).
1318
1319- Bug #1527397: PythonLauncher now launches scripts with the working directory
1320 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001321 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001322 expect.

1331-----------------
1332
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001333- Bug #1441486: The literal representation of -(sys.maxint - 1)
1334 again evaluates to a int object, not a long.
1335
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001336- Bug #1501934: The scope of global variables that are locally assigned
1337 using augmented assignment is now correctly determined.
1338
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001339- Bug #927248: Recursive method-wrapper objects can now safely
1340 be released.
1341
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001342- Bug #1417699: Reject locale-specific decimal point in float()
1343 and atof().
1344
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001345- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1346 omit a default "error" argument for NULL pointer. This allows
1347 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001348
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001349- Bug #1519018: 'as' is now validated properly in import statements.
1350
Neal Norwitz28746ab2006-07-09 22:14:42 +00001351- On 64 bit systems, int literals that use less than 64 bits are
1352 now ints rather than longs.
1353
Neal Norwitzed657552006-07-10 00:04:44 +00001354- Bug #1512814, Fix incorrect lineno's when code at module scope
1355 started after line 256.
1356
Tim Peters32a83612006-07-10 21:08:24 +00001357- New function ``sys._current_frames()`` returns a dict mapping thread
1358 id to topmost thread stack frame. This is for expert use, and is
1359 especially useful for debugging application deadlocks. The functionality
1360 was previously available in Fazal Majid's ``threadframe`` extension
1361 module, but it wasn't possible to do this in a wholly threadsafe way from
1362 an extension.

1368 VS 2003.
1369
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001370- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1371
Tim Peters32a83612006-07-10 21:08:24 +00001372- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001373 environment variable to be set in order to the SDK environment
1374 for finding the compiler, include files, etc.

1379
Thomas Woutersadd19112006-07-05 11:03:49 +00001380- string.Template() now correctly handles tuple-values. Previously,
1381 multi-value tuples would raise an exception and single-value tuples would
1382 be treated as the value they contain, instead.
1383
Martin v. Löwisede77f52006-07-03 13:01:35 +00001384- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1385 even if some data are received.
1386
Martin v. Löwis45482392006-07-03 12:28:58 +00001387- Bug #1267547: Put proper recursive setup.py call into the
1388 spec file generated by bdist_rpm.
1389
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001390- Bug #1514693: Update turtle's heading when switching between
1391 degrees and radians.
1392
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001393- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001394 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001395
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001396- Bug #1514703: Only setup canvas window in turtle when the canvas
1397 is created.
1398
Martin v. Löwis7596e832006-07-01 15:33:37 +00001399- Bug #1513223: .close() of a _socketobj now releases the underlying
1400 socket again, which then gets closed as it becomes unreferenced.
1401
Fred Drake10497c82006-06-29 02:57:48 +00001402- Bug #1504333: Make sgmllib support angle brackets in quoted
1403 attribute values.
1404
1405- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1406 sgmllib ('[' and ']' were not accepted).
1407
Georg Brandl1be63af2006-06-28 20:23:25 +00001408- Fix a bug in the turtle module's end_fill function.
1409
Brett Cannon53ab5b72006-06-22 16:49:14 +00001410- Bug #1510580: The 'warnings' module improperly required that a Warning
1411 category be either a types.ClassType and a subclass of Warning. The proper
1412 check is just that it is a subclass with Warning as the documentation states.
1413
Georg Brandlad29e632006-06-21 17:45:17 +00001414- The compiler module now correctly compiles the new try-except-finally
1415 statement (bug #1509132).
1416
Neal Norwitz60373cd2006-06-22 06:30:50 +00001417- The wsgiref package is now installed properly on Unix.
1418
Vinay Sajip28e57612006-07-01 10:45:20 +00001419- A bug was fixed in logging.config.fileConfig() which caused a crash on
1420 shutdown when fileConfig() was called multiple times.
1421
Gerhard Häring762fbd32006-07-02 17:48:30 +00001422- The sqlite3 module did cut off data from the SQLite database at the first
1423 null character before sending it to a custom converter. This has been fixed
1424 now.

1427-----------------
1428
Tim Peters112aad32006-07-19 00:03:19 +00001429- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1430 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1431 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001432
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001433- Assigning None to pointer type fields in ctypes structures possible
1434 overwrote the wrong fields, this is fixed now.
1435
1436- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1437 on non-Windows platforms.
1438
1439- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1440 integer or long, without range checking.
1441
1442- Patch #1517790: It is now possible to use custom objects in the ctypes
1443 foreign function argtypes sequence as long as they provide a from_param
1444 method, no longer is it required that the object is a ctypes type.
1445
1446- The '_ctypes' extension module now works when Python is configured
1447 with the --without-threads option.
1448
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001449- Bug #1513646: os.access on Windows now correctly determines write
1450 access, again.
1451
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001452- Bug #1512695: cPickle.loads could crash if it was interrupted with
1453 a KeyboardInterrupt.
1454
Neal Norwitza12aa882006-07-06 06:45:08 +00001455- Bug #1296433: parsing XML with a non-default encoding and
1456 a CharacterDataHandler could crash the interpreter in pyexpat.
1457
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001458- Patch #1516912: improve Modules support for OpenVMS.

1464
Tim Peters32a83612006-07-10 21:08:24 +00001465- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001466 Previously, the slight difference could cause compilation errors of the

1500Core and builtins
1501-----------------
1502
Georg Brandla56b9152006-06-19 06:35:54 +00001503- Patch #1507676: Error messages returned by invalid abstract object operations
1504 (such as iterating over an integer) have been improved and now include the
1505 type of the offending object to help with debugging.
1506
Brett Cannonea3912b2006-06-13 21:46:41 +00001507- Bug #992017: A classic class that defined a __coerce__() method that returned
1508 its arguments swapped would infinitely recurse and segfault the interpreter.
1509
Neal Norwitz909eb122006-06-12 02:13:21 +00001510- Fix the socket tests so they can be run concurrently.
1511
Neal Norwitzb9845e72006-06-12 02:11:18 +00001512- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001513 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001514
Brett Cannon22565aa2006-06-09 22:31:23 +00001515- Bug #532646: object.__call__() will continue looking for the __call__
1516 attribute on objects until one without one is found. This leads to recursion
1517 when you take a class and set its __call__ attribute to an instance of the
1518 class. Originally fixed for classic classes, but this fix is for new-style.
1519 Removes the infinite_rec_3 crasher.
1520
Georg Brandl24250812006-06-09 18:45:48 +00001521- The string and unicode methods startswith() and endswith() now accept
1522 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1523
Brett Cannonde3b0522006-06-08 17:00:45 +00001524- Buffer objects, at the C level, never used the char buffer
1525 implementation even when the char buffer for the wrapped object was
1526 explicitly requested (originally returned the read or write buffer).
1527 Now a TypeError is raised if the char buffer is not present but is
1528 requested.
1529
Georg Brandlddbaa662006-06-04 21:56:52 +00001530- Patch #1346214: Statements like "if 0: suite" are now again optimized
1531 away like they were in Python 2.4.
1532
Georg Brandlb7c8f542006-05-27 12:30:25 +00001533- Builtin exceptions are now full-blown new-style classes instead of
1534 instances pretending to be classes, which speeds up exception handling
1535 by about 80% in comparison to 2.5a2.
1536
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001537- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1538 Unicode 4.1.
1539
Georg Brandlf4ef1162006-05-26 18:03:31 +00001540- Patch #921466: sys.path_importer_cache is now used to cache valid and
1541 invalid file paths for the built-in import machinery which leads to
1542 fewer open calls on startup.
1543
Tim Peters696cf432006-05-24 21:10:40 +00001544- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1545 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1546 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1547 the number of input digits (it was and remains linear-time for bases
1548 2, 4, 8, 16 and 32).
1549
Tim Petersb713ec22006-05-23 18:45:30 +00001550- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1551 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1552 an integer close to ``sys.maxint``. This was repaired by patch
1553 #1335972, which also gives a nice speedup.
1554
Richard Jonescebbefc2006-05-23 18:28:17 +00001555- Patch #1337051: reduced size of frame objects.
1556
1557- PyErr_NewException now accepts a tuple of base classes as its
1558 "base" parameter.
1559
Richard Jones7c88dcc2006-05-23 10:37:38 +00001560- Patch #876206: function call speedup by retaining allocated frame
1561 objects.
1562
Georg Brandl7b90e162006-05-18 07:01:27 +00001563- Bug #1462152: file() now checks more thoroughly for invalid mode
1564 strings and removes a possible "U" before passing the mode to the
1565 C library function.
1566
Neal Norwitz1004a532006-05-15 07:17:23 +00001567- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1568
Neal Norwitz373f0a72006-05-15 07:04:36 +00001569- Bug #1487966: Fix SystemError with conditional expression in assignment
1570
Martin v. Löwis879768d2006-05-11 13:28:43 +00001571- WindowsError now has two error code attributes: errno, which carries
1572 the error values from errno.h, and winerror, which carries the error
1573 values from winerror.h. Previous versions put the winerror.h values
1574 (from GetLastError()) into the errno attribute.
1575
Martin v. Löwis77736712006-05-04 05:51:03 +00001576- Patch #1475845: Raise IndentationError for unexpected indent.
1577
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001578- Patch #1479181: split open() and file() from being aliases for each other.
1579
Tim Peters44bd9862006-06-01 13:49:23 +00001580- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1581 methods were always silently ignored by dictionaries when comparing keys.
1582 They are now passed through (except when using the C API function
1583 ``PyDict_GetItem()``, whose semantics did not change).
1584
1585- Bug #1456209: In some obscure cases it was possible for a class with a
1586 custom ``__eq__()`` method to confuse dict internals when class instances
1587 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1588 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001590Extension Modules
1591-----------------
1592
Trent Mick960a3f82006-06-28 20:30:41 +00001593- Bug #1295808: expat symbols should be namespaced in pyexpat
1594
1595- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1596
Brett Cannon6ee7d012006-06-08 16:23:04 +00001597- Change binascii.hexlify to accept a read-only buffer instead of only a char
1598 buffer and actually follow its documentation.
1599
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001600- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1601
Nick Coghlanc649ec52006-05-29 12:43:05 +00001602- Patch #1478788 (modified version): The functional extension module has
1603 been renamed to _functools and a functools Python wrapper module added.
1604 This provides a home for additional function related utilities that are
1605 not specifically about functional programming. See PEP 309.
1606
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001607- Patch #1493701: performance enhancements for struct module.
1608
Georg Brandl378d5922006-05-17 14:26:50 +00001609- Patch #1490224: time.altzone is now set correctly on Cygwin.
1610
Georg Brandl8d3342b2006-05-16 07:38:27 +00001611- Patch #1435422: zlib's compress and decompress objects now have a
1612 copy() method.
1613
Andrew MacIntyre92913322006-06-13 15:04:24 +00001614- Patch #1454481: thread stack size is now tunable at runtime for thread
1615 enabled builds on Windows and systems with Posix threads support.
1616
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001617- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1618 (up to the system limit of 32K characters).
1619
1620- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1621 As a result, these functions now raise WindowsError instead of OSError.
1622
Tim Peters7a822da2006-05-25 21:50:17 +00001623- ``time.clock()`` on Win64 should use the high-performance Windows
1624 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1625 Windows platforms).
1626
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001627- Calling Tk_Init twice is refused if the first call failed as that
1628 may deadlock.
1629
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001630- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1631 accept it without potentially using an uninitialized pointer.
1632
1633- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1634 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1635 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001636
Gregory P. Smith372b5832006-06-05 18:48:21 +00001637- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001638 [pybsddb project SF patch number 1466734]
1639
Gregory P. Smith372b5832006-06-05 18:48:21 +00001640- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1641 parameter is supplied. [SF pybsddb bug #1477863]
1642
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001643- bsddb: the __len__ method of a DB object has been fixed to return correct
1644 results. It could previously incorrectly return 0 in some cases.
1645 Fixes SF bug 1493322 (pybsddb bug 1184012).
1646
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001647- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1648 aborts the db transaction safely when a modifier callback fails.
1649 Fixes SF python patch/bug #1408584.
1650
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001651- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001652 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001653 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1654 database calls that would previously deadlock. [SF python bug #775414]
1655
Vinay Sajip28e57612006-07-01 10:45:20 +00001656- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001657
Walter Dörwald4994d952006-06-19 08:07:50 +00001658- Patch #1506645: add Python wrappers for the curses functions
1659 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001660

1662-------
1663
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001664- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1665 functions.
1666
Martin v. Löwis3798da02006-06-17 18:44:27 +00001667- Patch #812986: Update turtle output even if not tracing.
1668
Vinay Sajip28e57612006-07-01 10:45:20 +00001669- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001670 Tkinter.BaseWidget.
1671
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001672- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1673
Martin v. Löwis337487e2006-06-17 09:15:14 +00001674- Patch #763580: Add name and value arguments to Tkinter variable
1675 classes.
1676
Georg Brandl83cc0d02006-06-14 08:50:03 +00001677- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1678 mime.types file for determining MIME types.
1679
Georg Brandl2605ca82006-06-14 06:08:31 +00001680- Bug #1339007: Shelf objects now don't raise an exception in their
1681 __del__ method when initialization failed.
1682
Martin v. Löwisd8251432006-06-14 05:21:04 +00001683- Patch #1455898: The MBCS codec now supports the incremental mode for
1684 double-byte encodings.
1685
Tim Peters43898b42006-06-14 04:09:25 +00001686- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1687 guarantee that adjacent triples in the return list always describe
1688 non-adjacent blocks. Previously, a pair of matching blocks could end
1689 up being described by multiple adjacent triples that formed a partition
1690 of the matching pair.
1691
Greg Ward0e0c9f42006-06-11 16:24:11 +00001692- Bug #1498146: fix optparse to handle Unicode strings in option help,
1693 description, and epilog.
1694
Greg Wardd1c797e2006-06-11 14:42:41 +00001695- Bug #1366250: minor optparse documentation error.
1696
Greg Ward7f547402006-06-11 00:40:49 +00001697- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1698 clarify docs.
1699
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001700- The wsgiref package has been added to the standard library.
1701
Nick Coghlan676725d2006-06-08 13:54:49 +00001702- The functions update_wrapper() and wraps() have been added to the functools
1703 module. These make it easier to copy relevant metadata from the original
1704 function when writing wrapper functions.
1705
Tim Petersd6a9eef2006-06-05 01:48:21 +00001706- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1707 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001708
Martin v. Löwis3f767792006-06-04 19:36:28 +00001709- Patch #1359618: Speed up charmap encoder by using a trie structure
1710 for lookup.
1711
Tim Petersd609b1a2006-06-02 23:22:51 +00001712- The functions in the ``pprint`` module now sort dictionaries by key
1713 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1714 if and only if its display required more than one line, although that
1715 wasn't documented. The new behavior increases predictability; e.g.,
1716 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1717
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001718- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1719 (thanks for J. J. Lee).
1720
Georg Brandl2b330372006-05-28 20:23:12 +00001721- Patch #1496206: improve urllib2 handling of passwords with respect to
1722 default HTTP and HTTPS ports.
1723
George Yoshidaf3c65de2006-05-28 16:39:09 +00001724- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1725
Bob Ippolito7298f272006-05-23 18:43:47 +00001726- Patch #1281707: speed up gzip.readline.
1727
Georg Brandlb89316f2006-05-17 15:51:16 +00001728- Patch #1180296: Two new functions were added to the locale module:
1729 format_string() to get the effect of "format % items" but locale-aware,
1730 and currency() to format a monetary number with currency sign.
1731
Georg Brandle3a25832006-05-17 14:56:04 +00001732- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1733 and several features added, such as speed and geometry control.
1734
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001735- Patch #1488881: add support for external file objects in bz2 compressed
1736 tarfiles.
1737
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001738- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1739 stdout arguments, making it possible to redirect input and output
1740 for remote debugging.
1741
1742- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1743 a couple of issues, notably handling of long file names using the
1744 GNU LONGNAME extension.
1745
1746- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1747 new flag when ``name`` is already the name of an option flag.
1748
1749- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1750 package.
1751
1752- Patch #1472854: make the rlcompleter.Completer class usable on non-
1753 UNIX platforms.
1754
1755- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1756
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001757- Bug #1472827: correctly escape newlines and tabs in attribute values in

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001788What's New in Python 2.5 alpha 2?
1789=================================
1790
1791*Release date: 27-APR-2006*
1792
1793Core and builtins
1794-----------------
1795
Thomas Heller1b046642006-04-18 18:51:06 +00001796- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1797 by converting these apis from macros into exported functions again:
1798
1799 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1800 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1801 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1802 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1803 PyRun_String Py_CompileString
1804
Martin v. Löwis45294a92006-04-18 06:24:08 +00001805- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1806
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001807- All uses of PyStructSequence_InitType have been changed to initialize
1808 the type objects only once, even if the interpreter is initialized
1809 multiple times.
1810
Neal Norwitz61546162006-04-14 05:20:28 +00001811- Bug #1454485, array.array('u') could crash the interpreter. This was
1812 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1813 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1814
1815- Py_UNICODE is unsigned. It was always documented as unsigned, but
1816 due to a bug had a signed value in previous versions.
1817
Tim Peters3a5e8b12006-04-11 01:44:07 +00001818- Patch #837242: ``id()`` of any Python object always gives a positive
1819 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1820 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001821 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001822 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001823
Tim Peters3a5e8b12006-04-11 01:44:07 +00001824 def __hash__(self):
1825 return id(self) # WRONG
1826
1827 because a hash result must be a (short) Python int but it was always
1828 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001829 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001830 was always usable as a hash value before this patch. That's no longer
1831 necessarily so.
1832
1833- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001834 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001835 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001836 #1454844)
1837
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001838- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1839 involving generators that have paused outside of any ``try`` or ``with``
1840 blocks. (In 2.5a1, a paused generator that was part of a reference
1841 cycle could not be garbage collected, regardless of whether it was
1842 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001843
Anthony Baxter51bcb682006-04-05 14:51:42 +00001844Extension Modules

1846
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001847- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1848 is a macro.
1849
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001850- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1851 fails with an error condition.
1852
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001853- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1854
1855- Bug #1117761: bsddb.*open() no longer raises an exception when using
1856 the cachesize parameter.
1857
1858- Bug #1149413: bsddb.*open() no longer raises an exception when using
1859 a temporary db (file=None) with the 'n' flag to truncate on open.
1860
1861- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1862 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001863
Armin Rigoa9017c32006-04-19 11:50:27 +00001864- Patch #1062014: AF_UNIX sockets under Linux have a special
1865 abstract namespace that is now fully supported.
1866
Anthony Baxter51bcb682006-04-05 14:51:42 +00001867Library
1868-------
1869
Peter Astrand7d1d4362006-07-14 14:04:45 +00001870- Bug #1223937: subprocess.CalledProcessError reports the exit status
1871 of the process using the returncode attribute, instead of
1872 abusing errno.
1873
Tim Peters711bf302006-04-25 03:31:36 +00001874- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1875 a doctest to be skipped (the code is not run, and the expected output
1876 or exception is ignored).
1877
Nick Coghlanda2268f2006-04-24 04:37:15 +00001878- Fixed contextlib.nested to cope with exceptions being raised and
1879 caught inside exit handlers.
1880
Greg Wardab05edc2006-04-23 03:47:58 +00001881- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1882 hex, octal, or binary; add ``append_const`` action; keep going if
1883 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1884 added ``epilog`` for better help generation).
1885
Tim Peters21fbd572006-04-21 21:18:10 +00001886- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1887 called from a thread spawned as a side effect of importing a module.
1888
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001889- The pydoc module now supports documenting packages contained in
1890 .zip or .egg files.
1891
1892- The pkgutil module now has several new utility functions, such
1893 as ``walk_packages()`` to support working with packages that are either
1894 in the filesystem or zip files.
1895
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001896- The mailbox module can now modify and delete messages from
1897 mailboxes, in addition to simply reading them. Thanks to Gregory
1898 K. Johnson for writing the code, and to the 2005 Google Summer of
1899 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001900
Tim Petersc7605f22006-04-17 21:12:33 +00001901- The ``__del__`` method of class ``local`` in module ``_threading_local``
1902 returned before accomplishing any of its intended cleanup.
1903
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001904- Patch #790710: Add breakpoint command lists in pdb.
1905
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001906- Patch #1063914: Add Tkinter.Misc.clipboard_get().

Martin v. Löwis4b501e62006-04-15 08:41:11 +00001908- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1909
Anthony Baxtere29002c2006-04-12 12:07:31 +00001910- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1911 Windows. Bug #1469163.
1912
Phillip J. Eby47032112006-04-11 01:07:43 +00001913- The warnings, linecache, inspect, traceback, site, and doctest modules
1914 were updated to work correctly with modules imported from zipfiles or
1915 via other PEP 302 __loader__ objects.
1916
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001917- Patch #1467770: Reduce usage of subprocess._active to processes which
1918 the application hasn't waited on.
1919
Martin v. Löwisb04dee92006-04-10 08:34:21 +00001920- Patch #1462222: Fix Tix.Grid.
1921
Neal Norwitza31bf182006-04-09 03:35:43 +00001922- Fix exception when doing glob.glob('anything*/')
1923
Skip Montanaro262fb922006-04-21 02:31:07 +00001924- The pstats.Stats class accepts an optional stream keyword argument to
1925 direct output to an alternate file-like object.
1926
Anthony Baxter51bcb682006-04-05 14:51:42 +00001927Build
1928-----
1929
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001930- The Makefile now has a reindent target, which runs reindent.py on
1931 the library.
1932
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001933- Patch #1470875: Building Python with MS Free Compiler
1934
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001935- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001936
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001937- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1938 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001939 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001940 CXX from --with-cxx-main, see description in README.
1941
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001942- Patch #1429775: Link extension modules with the shared libpython.
1943
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001944- Fixed a libffi build problem on MIPS systems.
1945
Tim Peters8931ff12006-05-13 23:28:20 +00001946- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1947 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1948 and "%zu" for unsigned integers of type ``size_t``.
1949
Anthony Baxter51bcb682006-04-05 14:51:42 +00001950Tests
1951-----
1952
Nick Coghlanda2268f2006-04-24 04:37:15 +00001953- test_contextlib now checks contextlib.nested can cope with exceptions
1954 being raised and caught inside exit handlers.
1955
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001956- test_cmd_line now checks operation of the -m and -c command switches
1957
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001958- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1959 it separately and by hand. It also wasn't cleaning up its changes to
1960 the current Decimal context.
1961
Thomas Woutersabd08882006-04-26 15:53:30 +00001962- regrtest.py now has a -M option to run tests that test the new limits of
1963 containers, on 64-bit architectures. Running these tests is only sensible
1964 on 64-bit machines with more than two gigabytes of memory. The argument
1965 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001973Documentation
1974-------------
1975
Tim Petersb06d28c2006-05-12 01:57:59 +00001976- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1977
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001978- PEP 343: Added Context Types section to the library reference
1979 and attempted to bring other PEP 343 related documentation into
1980 line with the implementation and/or python-dev discussions.
1981
Tim Peters8dc73d22006-04-24 02:03:16 +00001982- Bug #1337990: clarified that ``doctest`` does not support examples
1983 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001986What's New in Python 2.5 alpha 1?
1987=================================
1988
Anthony Baxterebed3f62006-04-03 15:03:44 +00001989*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001990
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001991Core and builtins
1992-----------------
1993
Nick Coghlan43832302006-04-23 17:04:07 +00001994- PEP 338: -m command line switch now delegates to runpy.run_module
1995 allowing it to support modules in packages and zipfiles
1996
Martin v. Löwisc661b882006-04-20 04:54:23 +00001997- On Windows, .DLL is not an accepted file name extension for
1998 extension modules anymore; extensions are only found if they
1999 end in .PYD.
2000
Martin v. Löwisea62d252006-04-03 10:56:49 +00002001- Bug #1421664: sys.stderr.encoding is now set to the same value as
2002 sys.stdout.encoding.
2003
Neal Norwitz92e212f2006-04-03 04:48:37 +00002004- __import__ accepts keyword arguments.
2005
Georg Brandlccadf842006-03-31 18:54:53 +00002006- Patch #1460496: round() now accepts keyword arguments.
2007
Anthony Baxter262c00a2006-03-30 10:53:17 +00002008- Fixed bug #1459029 - unicode reprs were double-escaped.
2009
Hye-Shik Changd478f342006-03-23 12:32:36 +00002010- Patch #1396919: The system scope threads are reenabled on FreeBSD
2011 5.4 and later versions.
2012
Neal Norwitze98ccf62006-03-23 05:39:47 +00002013- Bug #1115379: Compiling a Unicode string with an encoding declaration
2014 now gives a SyntaxError.
2015
Georg Brandlabd1ff82006-03-18 07:59:59 +00002016- Previously, Python code had no easy way to access the contents of a
2017 cell object. Now, a ``cell_contents`` attribute has been added
2018 (closes patch #1170323).
2019
Tim Peterscf79aac2006-03-16 01:14:46 +00002020- Patch #1123430: Python's small-object allocator now returns an arena to
2021 the system ``free()`` when all memory within an arena becomes unused
2022 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2023 freed. Some applications will see a drop in virtual memory size now,
2024 especially long-running applications that, from time to time, temporarily
2025 use a large number of small objects. Note that when Python returns an
2026 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002027 platform C library will in turn return that memory to the operating system.
2028 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002029 appears to be effective at least on Microsoft C and gcc-based systems.
2030 Thanks to Evan Jones for hard work and patience.
2031
Georg Brandl533ff6f2006-03-08 18:09:27 +00002032- Patch #1434038: property() now uses the getter's docstring if there is
2033 no "doc" argument given. This makes it possible to legitimately use
2034 property() as a decorator to produce a read-only property.
2035
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002036- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2037 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2038 of requiring an int or long in slicing and a few other contexts, enabling
2039 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2040
Neal Norwitz995acdf2006-03-07 05:01:00 +00002041- Fixed various bugs reported by Coverity's Prevent tool.
2042
Brett Cannonbf364092006-03-01 04:25:17 +00002043- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2044 new exception base class, BaseException, which has a new message attribute.
2045 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2046 Raising a string exception now raises a DeprecationWarning.
2047
Thomas Woutersfb609f42006-02-28 16:37:25 +00002048- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2049 explicitly relative, using 'from .module import name' to mean 'from the same
2050 package as this module is in. Imports without dots still default to the
2051 old relative-then-absolute, unless 'from __future__ import
2052 absolute_import' is used.
2053
Brett Cannona7446e32006-02-27 23:39:10 +00002054- Properly check if 'warnings' raises an exception (usually when a filter set
2055 to "error" is triggered) when raising a warning for raising string
2056 exceptions.
2057
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002058- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002059 The name was removed from Include/code.h.
2060
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002061- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002062
Guido van Rossum1968ad32006-02-25 22:38:04 +00002063- Patch 1433928:
2064 - The copy module now "copies" function objects (as atomic objects).
2065 - dict.__getitem__ now looks for a __missing__ hook before raising
2066 KeyError.
2067
Tim Peters84ef21c2006-02-28 20:39:06 +00002068- PEP 343: with statement implemented. Needs ``from __future__ import
2069 with_statement``. Use of 'with' as a variable will generate a warning.
2070 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002071 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002072 The following objects have __context__ methods:
2073 - The built-in file type.
2074 - The thread.LockType type.
2075 - The following types defined by the threading module:
2076 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2077 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002078
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002079- Fix the encodings package codec search function to only search
2080 inside its own package. Fixes problem reported in patch #1433198.
2081
2082 Note: Codec packages should implement and register their own
2083 codec search function. PEP 100 has the details.
2084
Tim Peters9ea89d22006-06-04 03:26:02 +00002085- PEP 353: Using ``Py_ssize_t`` as the index type.
2086
2087- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2088 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2089 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2090 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2091 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002092
Neal Norwitzfc76d632006-01-10 06:03:13 +00002093- Patch #1400181, fix unicode string formatting to not use the locale.
2094 This is how string objects work. u'%f' could use , instead of .
2095 for the decimal point. Now both strings and unicode always use periods.
2096
Neal Norwitz671b9e32006-01-09 07:07:12 +00002097- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2098 configure would break checking curses.h.
2099
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002100- Bug #959576: The pwd module is now builtin. This allows Python to be
2101 built on UNIX platforms without $HOME set.
2102
Neal Norwitzc10978f2005-12-19 06:07:16 +00002103- Bug #1072182, fix some potential problems if characters are signed.
2104
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002105- Bug #889500, fix line number on SyntaxWarning for global declarations.
2106
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002107- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2108
Neal Norwitze7214a12005-12-18 05:03:17 +00002109- Support for converting hex strings to floats no longer works.
2110 This was not portable. float('0x3') now raises a ValueError.
2111
Barry Warsaw2a38a862005-12-18 01:27:35 +00002112- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002113 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002114 is now displayed in interactive prompt banner.
2115
Georg Brandlfa166682005-12-17 21:45:17 +00002116- Implementation of PEP 341 - Unification of try/except and try/finally.
2117 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002118 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002119
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002120- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2121 now encodes backslash correctly.
2122
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002123- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2124
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002125- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002126 and long longs.
2127
Neal Norwitz67715f02005-11-09 06:59:35 +00002128- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002129 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002130 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002131
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002132- Replaced most Unicode charmap codecs with new ones using the
2133 new Unicode translate string feature in the builtin charmap
2134 codec; the codecs were created from the mapping tables available
2135 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2136 encodings now include a mapping for the Apple logo)
2137
Tim Peterse3547fd2005-12-16 23:13:57 +00002138- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002139
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002140- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002141
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002142- A new AST parser implementation was completed. The abstract
2143 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002144 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002145
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002146- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002147 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2148
Neal Norwitz708e51a2005-10-03 04:48:15 +00002149- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2150
Neal Norwitz11bd1192005-10-03 00:54:56 +00002151- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2152 Provide a warning when a directory is passed on the command line.
2153
Neal Norwitz40d37812005-10-02 01:48:49 +00002154- Fix segfault with invalid coding.
2155
2156- SF bug #772896: unknown encoding results in MemoryError.
2157
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002158- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002159 supported a __len__() method which evaluated to False when the iterator
2160 was empty.
2161
Guido van Rossum630db602005-09-20 18:49:54 +00002162- On 64-bit platforms, when __len__() returns a value that cannot be
2163 represented as a C int, raise OverflowError.
2164
Skip Montanarof8948ca2005-09-19 03:54:46 +00002165- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002166 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002167
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002168- SF bug #893549: parsing keyword arguments was broken with a few format
2169 codes.
2170
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002171- Changes donated by Elemental Security to make it work on AIX 5.3
2172 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2173 bug #105470: test_pwd fails on 64bit system (Opteron).
2174
Guido van Rossum539c6622005-09-14 17:49:54 +00002175- Changes donated by Elemental Security to make it work on HP-UX 11 on
2176 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2177
Georg Brandl4550b8d2005-08-26 06:43:52 +00002178- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002179 (fixes bug #1119418).
2180
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002181- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2182
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002183- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2184 exceptions that cause a function to exit.
2185
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002186- The implementation of set() and frozenset() was revised to use its
2187 own internal data structure. Memory consumption is reduced by 1/3
2188 and there are modest speed-ups as well. The API is unchanged.
2189
Tim Petersde7990b2005-07-17 23:45:23 +00002190- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2191
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002192- SF bug #1229429: PyObject_CallMethod failed to decrement some
2193 reference counts in some error exit cases.
2194
Tim Petersecc6e6a2005-07-10 22:30:55 +00002195- SF bug #1185883: Python's small-object memory allocator took over
2196 a block managed by the platform C library whenever a realloc specified
2197 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002198 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002199 portable way to copy data from the C-managed block into Python's
2200 small-object space without risking a memory fault. Python's small-object
2201 realloc now leaves such blocks under the control of the platform C
2202 realloc.
2203
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002204- SF bug #1232517: An overflow error was not detected properly when
2205 attempting to convert a large float to an int in os.utime().
2206
Raymond Hettinger3296e692005-06-29 23:29:56 +00002207- SF bug #1224347: hex longs now print with lowercase letters just
2208 like their int counterparts.
2209
Michael W. Hudson188d4362005-06-20 16:52:57 +00002210- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2211 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2212 interpreter states; back out that fix and do a better job (see
2213 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2214 for a longer write-up of the problem).
2215
Michael W. Hudsondf888462005-06-03 14:41:55 +00002216- SF patch #1180995: marshal now uses a binary format by default when
2217 serializing floats.
2218
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002219- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2220 the routines that promise to produce IEEE 754 binary representations
2221 of floats now simply copy bytes around.
2222
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002223- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2224 278.
2225
Brett Cannonc3647ac2005-04-26 03:45:26 +00002226- patch #1109424: int, long, float, complex, and unicode now check for the
2227 proper magic slot for type conversions when subclassed. Previously the
2228 magic slot was ignored during conversion. Semantics now match the way
2229 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002230 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002231 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002232 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002233
Barry Warsawc8d907c2005-04-19 23:43:40 +00002234- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2235 NULL, now raise an AttributeError when attempting to set or delete the
2236 attribute. Previously a TypeError was raised, but this was inconsistent
2237 with the equivalent pure-Python implementation.
2238
Michael W. Hudson774479c2005-04-18 08:46:17 +00002239- It is now safe to call PyGILState_Release() before
2240 PyEval_InitThreads() (note that if there is reason to believe there
2241 are multiple threads around you still must call PyEval_InitThreads()
2242 before using the Python API; this fix is for extension modules that
2243 have no way of knowing if Python is multi-threaded yet).
2244
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002245- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2246 disabled caused a crash.
2247
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002248- Bug #1165306: instancemethod_new allowed the creation of a method
2249 with im_class == im_self == NULL, which caused a crash when called.
2250
Tim Petersecc6e6a2005-07-10 22:30:55 +00002251- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002252 fixes the crash seen in bug #1165761
2253
Raymond Hettinger96229b12005-03-11 06:49:40 +00002254- Added two new builtins, any() and all().
2255
Brett Cannon409d8f22005-03-05 06:47:57 +00002256- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002257 (e.g., ``class C(): pass`` is no longer a syntax error).
2258 Patch #1176012 added support to the 'parser' module and 'compiler' package
2259 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002260
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002261- Patch #1115086: Support PY_LONGLONG in structmember.
2262
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002263- Bug #1155938: new style classes did not check that __init__() was
2264 returning None.
2265
Tim Petersecc6e6a2005-07-10 22:30:55 +00002266- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002267 ('\') with a specific error message.
2268
Martin v. Löwisff232d72005-03-03 09:24:38 +00002269- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2270
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002271- Bug #1124295: the __name__ attribute of file objects was
2272 inadvertently made inaccessible in restricted mode.
2273
Tim Petersecc6e6a2005-07-10 22:30:55 +00002274- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002275 an ferror() call.
2276
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002277- min() and max() now support key= arguments with the same meaning as in
2278 list.sort().
2279
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002280- The peephole optimizer now performs simple constant folding in expressions:
2281 (2+3) --> (5).
2282
Raymond Hettingera422c342005-01-11 03:03:27 +00002283- set and frozenset objects can now be marshalled. SF #1098985.
2284
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002285- Bug #1077106: Poor argument checking could cause memory corruption
2286 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002287
Jeremy Hyltonab630502005-02-04 18:44:06 +00002288- The parser did not complain about future statements in illegal
2289 positions. It once again reports a syntax error if a future
2290 statement occurs after anything other than a doc string.
2291
Neil Schemenauercf52c072005-08-12 17:34:58 +00002292- Change the %s format specifier for str objects so that it returns a
2293 unicode instance if the argument is not an instance of basestring and
2294 calling __str__ on the argument returns a unicode instance.
2295
Tim Petersf4e69282006-02-27 17:15:31 +00002296- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2297 current thread state when the auto-GIL-state machinery knows about
2298 it (since the thread state is being deleted, continuing to remember it
2299 can't help, but can hurt if another thread happens to get created with
2300 the same thread id).
2301
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002302Extension Modules
2303-----------------
2304
Georg Brandl43f08a82006-03-31 18:01:16 +00002305- Patch #1380952: fix SSL objects timing out on consecutive read()s
2306
Neal Norwitz05a45592006-03-20 06:30:08 +00002307- Patch #1309579: wait3 and wait4 were added to the posix module.
2308
Anthony Baxterfa869072006-03-20 05:21:58 +00002309- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
2310 In addition, the existing ulaw code was updated.
2311
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002312- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00002313 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002314
Neal Norwitz10be10c2006-03-16 06:50:13 +00002315- Everything under lib-old was removed. This includes the following modules:
2316 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00002317 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00002318 util, whatsound, whrandom, zmod
2319
2320- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2321
2322- re and sre were swapped, so help(re) provides full help. importing sre

2478
Raymond Hettingerb2594052004-12-05 09:25:51 +00002479- itertools.islice() now accepts None for the start and step arguments.
2480 This allows islice() to work more readily with slices:

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002492- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2493 been renamed to have only a single underscore prefix. This was done to
2494 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002495
Nick Coghlan43832302006-04-23 17:04:07 +00002496- PEP 338: new module runpy defines a run_module function to support
2497 executing modules which provide access to source code or a code object
2498 via the PEP 302 import mechanisms.
2499
Anthony Baxter93f5b932006-04-03 08:05:07 +00002500- The email module's parsedate_tz function now sets the daylight savings

2508 in attribute values.
2509
Anthony Baxterc51ee692006-04-01 00:57:31 +00002510- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002511 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002512 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002513 module will not be built.
2514
Tim Petersc17976e2006-04-01 00:26:53 +00002515- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2516 aren't officially supported here, and trying to use them will probably
2517 raise an exception some day. But dicts have been allowed, and "mostly
2518 worked", so support for them won't go away without warning.
2519
Georg Brandl338ef7d2006-03-31 18:42:16 +00002520- Bug #1445068: getpass.getpass() can now be given an explicit stream
2521 argument to specify where to write the prompt.
2522

2538
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002539- email 4.0 package now integrated. This is largely the same as the email 3.0
2540 package that was included in Python 2.3, except that PEP 8 module names are
2541 now used (e.g. mail.message instead of email.Message). The MIME classes
2542 have been moved to a subpackage (e.g. email.mime.text instead of
2543 email.MIMEText). The old names are still supported for now. Several
2544 deprecated Message methods have been removed and lots of bugs have been
2545 fixed. More details can be found in the email package documentation.
2546
Walter Dörwald40108c92006-03-27 08:15:44 +00002547- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2548 (a subclass of tuple) that provides incremental decoders and encoders
2549 (a way to use stateful codecs without the stream API). Python functions
2550 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2551 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2552 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00002554- Patch #1359365: Calling next() on a closed StringIO.String object raises
2555 a ValueError instead of a StopIteration now (like file and cString.String do).
2556 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2557 called before (like file and StringIO.StringIO do).

2627 LoadError as documented, instead of IOError. For compatibility,
2628 LoadError subclasses IOError.
2629
Brett Cannon3cbd0382005-12-16 22:49:23 +00002630- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00002631 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2632 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2633 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2634 Ronald L. Rivest offered this advice for Python:
2635
2636 "The consensus of researchers in this area (at least as
2637 expressed at the NIST Hash Function Workshop 10/31/05),
2638 is that SHA-256 is a good choice for the time being, but
2639 that research should continue, and other alternatives may
2640 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002641
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002642- Added a subset of Fredrik Lundh's ElementTree package. Available

2695 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002696 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002697

2736
Raymond Hettinger68c04532005-06-10 11:05:19 +00002737- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002738 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002739 the generate_tokens() function now accepts a callable argument that

2760 allows other classes to implement __radd__ style methods and have them
2761 work as expected.
2762
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002763- Bug #1163325: Decimal infinities failed to hash. Attempting to

Guido van Rossumd0641422005-02-03 15:01:24 +00002801- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2802 disables recursive traversal through instance attributes, which can
2803 be exploited in various ways.
2804
Tim Peterse3547fd2005-12-16 23:13:57 +00002805- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec

2819
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002820- Enhancements to the csv module:
2821
2822 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002823 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002824 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002825 + Dialect parameter parsing has been re-implemented to improve error
2826 reporting.
2827 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2828 dictates.
2829 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002830 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002831 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002832 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2833 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002834 + reader now allows \r characters to be quoted (previously it only allowed
2835 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002836 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002837 + Dialect classes passed to the module are no longer instantiated by
2838 the module before being parsed (the former validation scheme required
2839 this, but the mechanism was unreliable).
2840 + The dialect registry now contains instances of the internal
2841 C-coded dialect type, rather than references to python objects.
2842 + the internal c-coded dialect type is now immutable.
2843 + register_dialect now accepts the same keyword dialect specifications
2844 as the reader and writer, allowing the user to register dialects
2845 without first creating a dialect class.
2846 + a configurable limit to the size of parsed fields has been added -
2847 previously, an unmatched quote character could result in the entire
2848 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002849 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002850 the parser field size limit (returning the former limit). The initial
2851 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002852 + A line_num attribute has been added to the reader object, which tracks
2853 the number of lines read from the source iterator. This is not
2854 the same as the number of records returned, as records can span
2855 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002856 + reader and writer objects were not being registered with the cyclic-GC.
2857 This has been fixed.
2858
Brett Cannone6539c42005-01-08 02:43:53 +00002859- _DummyThread objects in the threading module now delete self.__block that is
2860 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2861 lock primitives tend to be limited in number and thus should not be wasted on
2862 a _DummyThread object. Fixes bug #1089632.
2863
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002864- The imghdr module now detects Exif files.
2865
Raymond Hettinger6065d322004-12-20 23:51:53 +00002866- StringIO.truncate() now correctly adjusts the size attribute.
2867 (Bug #951915).
2868
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002869- locale.py now uses an updated locale alias table (built using
2870 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2871 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002872 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002873
Raymond Hettinger3557f422004-12-07 12:02:02 +00002874- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2875
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002876- the pickle module no longer accepts the deprecated None option in the
2877 args tuple returned by __reduce__().
2878
Brett Cannon84667c02004-12-07 03:25:18 +00002879- optparse now optionally imports gettext. This allows its use in setup.py.
2880
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002881- the pickle module no longer uses the deprecated bin parameter.
2882
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002883- the shelve module no longer uses the deprecated binary parameter.
2884
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002885- the pstats module no longer uses the deprecated ignore() method.
2886
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002887- the filecmp module no longer uses the deprecated use_statcache argument.
2888
Raymond Hettinger664347b2004-12-04 21:21:53 +00002889- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2890 extended or overridden by subclasses. Formerly, the subclassed method would
2891 be ignored by the rest of the module. (Bug #1078905).
2892
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002893- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002894 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002895
Walter Dörwald36733692004-12-22 12:50:50 +00002896- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2897 once when a size argument is given. This prevents a buffer overflow in the
2898 tokenizer with very long source lines.
2899
Barry Warsaw538561e2006-01-01 21:48:54 +00002900- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2901 immediately after creating the object, without any intervening
2902 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002903
Skip Montanaro05885812005-01-16 20:48:27 +00002904- The reconvert.quote function can now emit triple-quoted strings. The
2905 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002906
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002907- ``UserString.MutableString`` now supports negative indices in
2908 ``__setitem__`` and ``__delitem__``
2909
Greg Ward40407942005-03-05 02:53:17 +00002910- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2911 correctly.
2912
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002913- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2914 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2915 character even if the user has passed a size parameter to get a proper
2916 line ending. Remove the special handling of a "\r\n" that has been split
2917 between two lines.
2918
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002919- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2920 about illegal code points. The codec now supports PEP 293 style error
2921 handlers.
2922
Walter Dörwald78a78b02005-09-01 12:04:29 +00002923- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002924 from the input stream, so that the output is a byte string in the correct
2925 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002926
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002927- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2928 considering it exactly like a '*'.
2929
Walter Dörwald007f8df2005-10-09 19:42:27 +00002930- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2931 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002932
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002933- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2934
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002935- Patch #1413711: Certain patterns of differences were making difflib
2936 touch the recursion limit.
2937
Walter Dörwald58917a62006-03-31 15:26:22 +00002938- Bug #947906: An object oriented interface has been added to the calendar
2939 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002940 called as a script (e.g. via ``python -mcalendar``). Localized month and
2941 weekday names can be ouput (even if an exotic encoding is used) using
2942 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002943
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002944Build
2945-----
2946
Neal Norwitz602d3392006-03-31 08:21:40 +00002947- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2948 by using -mieee gcc option.
2949
Martin v. Löwis86d66262006-02-17 08:40:11 +00002950- Patch #1432345: Make python compile on DragonFly.
2951
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002952- Build support for Win64-AMD64 was added.
2953
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002954- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2955
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002956- Patch #881820: look for openpty and forkpty also in libbsd.
2957
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002958- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2959 The zlib module is now builtin on Windows.
2960
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002961- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2962
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002963- Bug #1189330: configure did not correctly determine the necessary
2964 value of LINKCC if python was built with GCC 4.0.
2965
Trent Mick8321b422005-07-26 02:29:21 +00002966- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2967 vulnerability in zlib 1.2.1 and 1.2.2.
2968
Brett Cannon08cd5982005-04-24 22:26:38 +00002969- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2970 flags that change binary compatibility. Changes were also made to
2971 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002972 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002973
Bob Ippolitoed233462005-03-29 13:47:59 +00002974- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2975 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2976 no longer exists). This configure patch makes things right.
2977
Martin v. Löwise2713be2005-03-08 15:03:08 +00002978- Bug #1158607: Build with --disable-unicode again.
2979
Brett Cannon46d96232005-02-16 00:07:19 +00002980- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2981 defined. Discovered as a result of not being able to build on OS X.
2982
Brett Cannon516592f2004-12-07 00:42:59 +00002983- setup.py now uses the directories specified in LDFLAGS using the -L option
2984 and in CPPFLAGS using the -I option for adding library and include
2985 directories, respectively, for compiling extension modules against. This has
2986 led to the core being compiled using the values in CPPFLAGS. It also removes
2987 the need for the special-casing of both DarwinPorts and Fink for darwin since
2988 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2989 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2990 Fink, ``-I/opt/local/include`` for DarwinPorts).
2991
Brett Cannon43802422005-02-10 20:48:03 +00002992- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2993 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2994 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2995 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002997C API
2998-----
2999
Tim Petersc9d78aa2006-03-26 23:27:58 +00003000- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3001 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3002 is obtained via the ``PyObject_`` family, it must be released via the
3003 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3004 always been officially true, but when Python's small-object allocator was
3005 introduced, an attempt was made to cater to a few extension modules
3006 discovered at the time that obtained memory via ``PyObject_New`` but
3007 released it via ``PyMem_DEL``. It's years later, and if such code still
3008 exists it will fail now (probably with segfaults, but calling wrong
3009 low-level memory management functions can yield many symptoms).
3010
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003011- Added a C API for set and frozenset objects.
3012
Raymond Hettinger66517482004-12-03 11:45:13 +00003013- Removed PyRange_New().
3014
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003015- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3016 mapping argument now. This string is used as a mapping table. Byte values
3017 greater than the length of the string and 0xFFFE are treated as undefined
3018 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003025
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00003026- Patch #1276356: New resource "urlfetch" is implemented. This enables
