Thomas Heller8bf469d2007-03-09 20:48:57 +0000580- Bug #1651235: When a tuple was passed to a ctypes function call,
581 Python would crash instead of raising an error.

589
Georg Brandld59ea472007-03-08 18:37:35 +0000590- unittest now verifies more of its assumptions. In particular, TestCase
591 and TestSuite subclasses (not instances) are no longer accepted in
592 TestSuite.addTest(). This should cause no incompatibility since it
593 never made sense with ordinary subclasses -- the failure just occurred
594 later, with a more cumbersome exception.

Neal Norwitzff4b63b2006-08-04 04:50:21 +0000948
949Core and builtins
950-----------------
951
Neal Norwitz24b6f202006-09-05 04:43:56 +0000952- Fix infinite recursion when subclassing long and overriding __hash__.
953
954- Fix concatenation (+=) of long strings.
955
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000956- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000957 compared equal or unequal to a string and a UnicodeDecodeError
958 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000959
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000960 Instead, the equal (==) and unequal (!=) comparison operators will
961 now issue a UnicodeWarning and interpret the two objects as
962 unequal. The UnicodeWarning can be filtered as desired using
963 the warning framework, e.g. silenced completely, turned into an
964 exception, logged, etc.
965
966 Note that compare operators other than equal and unequal will still
967 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000968
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000969- Fix segfault when doing string formatting on subclasses of long.
970
971- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
972 with new-style classes.
973
974- Fix bug related to __len__ functions returning negative values with
975 classic classes.
976
977- Patch #1538606, Fix __index__() clipping. There were some problems
978 discovered with the API and how integers that didn't fit into Py_ssize_t
979 were handled. This patch attempts to provide enough alternatives
980 to effectively use __index__.
981
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000982- Bug #1536021: __hash__ may now return long int; the final hash
983 value is obtained by invoking hash on the long int.
984
Thomas Hellerab1049c2006-08-08 17:37:00 +0000985- Bug #1536786: buffer comparison could emit a RuntimeWarning.
986
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000987- Bug #1535165: fixed a segfault in input() and raw_input() when
988 sys.stdin is closed.
989
Thomas Heller74d36f02006-08-04 18:17:40 +0000990- On Windows, the PyErr_Warn function is now exported from
991 the Python dll again.
992
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000993- Bug #1191458: tracing over for loops now produces a line event
994 on each iteration. Fixing this problem required changing the .pyc
995 magic number. This means that .pyc files generated before 2.5c1
996 will be regenerated.
997
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000998- Bug #1333982: string/number constants were inappropriately stored
999 in the byte code and co_consts even if they were not used, ie
1000 immediately popped off the stack.
1001
Georg Brandle9462c72006-08-04 18:03:37 +00001002- Fixed a reference-counting problem in property().

1005Library
1006-------
1007
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001008- Fix a bug in the ``compiler`` package that caused invalid code to be
1009 generated for generator expressions.
1010
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001011- The distutils version has been changed to 2.5.0. The change to
1012 keep it programmatically in sync with the Python version running
1013 the code (introduced in 2.5b3) has been reverted. It will continue
1014 to be maintained manually as static string literal.
1015
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001016- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001017 and this cannot be converted to the required C type, an exception is
1018 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001019 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001020
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001021- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001022 an exception.
1023
Tim Peterscbdd3502006-09-05 01:47:53 +00001024- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001025 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001026 workarounds for clocks with low resolution, to stop the code yielding
1027 duplicate UUIDs.
1028
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001029- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1030 before raising SystemExit, allowing IDLE to honor quit() and exit().
1031
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001032- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1033
Georg Brandl7a1af772006-08-14 21:55:28 +00001034- Patch #1536071: trace.py should now find the full module name of a
1035 file correctly even on Windows.
1036
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001037- logging's atexit hook now runs even if the rest of the module has
1038 already been cleaned up.
1039
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001040- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001041
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001042- Bug #1531405, format_exception no longer raises an exception if
1043 str(exception) raised an exception.
1044
Neil Schemenauer06ded092006-08-04 16:20:30 +00001045- Fix a bug in the ``compiler`` package that caused invalid code to be
1046 generated for nested functions.

1057 raises the correct exceptions.
1058
Thomas Heller1ce433e2006-08-14 16:20:04 +00001059- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1060 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1061
Thomas Heller86720042006-08-14 11:17:48 +00001062- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1063 uses the _as_parameter_ attribute when objects are passed to foreign
1064 function calls. The ctypes version number was changed to 1.0.1.
1065
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001066- Bug #1530559, struct.pack raises TypeError where it used to convert.
1067 Passing float arguments to struct.pack when integers are expected
1068 now triggers a DeprecationWarning.

Neal Norwitza1f10902006-07-12 07:28:29 +00001117
1118Core and builtins
1119-----------------
1120
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001121- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001122 returned a long (see PEP 353).
1123
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001124- Bug #1515471: string.replace() accepts character buffers again.
1125
Neal Norwitz07aadb12006-07-30 06:55:48 +00001126- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1127 This provides the proper warning for struct.pack().
1128 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1129
Neal Norwitz0d62a062006-07-30 06:53:31 +00001130- Patch #1531113: Fix augmented assignment with yield expressions.
1131 Also fix a SystemError when trying to assign to yield expressions.
1132
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001133- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1134 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1135 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1136 excessive filesystem operations during imports.
1137
Tim Petersbc24eee2006-07-27 01:14:53 +00001138- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1139 operations on signed longs that are formally undefined by C.
1140 Unfortunately, at least one compiler now cares about that, so complicated
1141 the code to make that compiler happy again.
1142
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001143- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1144
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001145- Patch #1232023: Stop including current directory in search
1146 path on Windows.
1147
Neal Norwitze1fdb322006-07-21 05:32:28 +00001148- Fix some potential crashes found with failmalloc.
1149
Neal Norwitze7563102006-07-17 01:00:16 +00001150- Fix warnings reported by Klocwork's static analysis tool.
1151
Neal Norwitz84be93b2006-07-16 01:50:38 +00001152- Bug #1512814, Fix incorrect lineno's when code within a function
1153 had more than 255 blank lines.
1154
Georg Brandl9dceedb2006-07-12 15:31:17 +00001155- Patch #1521179: Python now accepts the standard options ``--help`` and
1156 ``--version`` as well as ``/?`` on Windows.
1157
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001158- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001159 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001160 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001161
Tim Peters112aad32006-07-19 00:03:19 +00001162- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001163 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001164 new ``sys._current_frames()`` returns a dictionary with one entry,
1165 mapping the faux "thread id" 0 to the current frame.
1166
Ronald Oussoren3075e162006-07-25 20:28:55 +00001167- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001168

1172
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001173- Correction of patch #1455898: In the mbcs decoder, set final=False
1174 for stream decoder, but final=True for the decode function.
1175
Georg Brandl07fec3a2006-08-01 18:49:24 +00001176- os.urandom no longer masks unrelated exceptions like SystemExit or
1177 KeyboardInterrupt.
1178
Tim Peters4643c2f2006-08-10 22:45:34 +00001179- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001180 shutil.copytree on Windows
1181
Georg Brandle34ac7c2006-07-30 11:07:23 +00001182- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1183 refers to file descriptors, not file objects.
1184
Tim Peterscbdd3502006-09-05 01:47:53 +00001185- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001186 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001187 #1513611, and probably others.
1188
Georg Brandledd9b0d2006-07-29 09:33:26 +00001189- Bug #1441397: The compiler module now recognizes module and function
1190 docstrings correctly as it did in Python 2.4.
1191
Tim Peters6f681472006-07-27 23:44:37 +00001192- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1193 lost that tests are sorted by name before being run. This rarely
1194 matters for well-written tests, but can create baffling symptoms if
1195 side effects from one test to the next affect outcomes. ``DocTestFinder``
1196 has been changed to sort the list of tests it returns.
1197
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001198- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001199 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001200
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001201- Bug #978833: Really close underlying socket in _socketobject.close.
1202
Georg Brandldb232dc2006-08-20 13:15:43 +00001203- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1204 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001205
Georg Brandlcf0c1722006-07-26 07:23:32 +00001206- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1207 to recursive calls and call it with the failing package name.
1208
Martin v. Löwis0b483032006-07-25 09:53:12 +00001209- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1210
Georg Brandlc13c34c2006-07-24 14:09:56 +00001211- Patch #1515343: Fix printing of deprecated string exceptions with a
1212 value in the traceback module.
1213
Greg Ward48fae7a2006-07-23 16:05:51 +00001214- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1215
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001216- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1217
Brett Cannoncaebe222006-07-18 04:41:36 +00001218- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1219 argument tuple. For arguments where zero is illegal, the value is forced to
1220 the minimum value that is correct. This is to support an undocumented but
1221 common way people used to fill in inconsequential information in the time
1222 tuple pre-2.4.
1223
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001224- Patch #1220874: Update the binhex module for Mach-O.
1225
Barry Warsawb110bad2006-07-21 14:51:07 +00001226- The email package has improved RFC 2231 support, specifically for
1227 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1228 (name*0=<blah>) parameter continuations. This may change the types of
1229 values returned from email.message.Message.get_param() and friends.
1230 Specifically in some cases where non-encoded continuations were used,
1231 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1232 will just return the string (since non-encoded continuations don't have
1233 charset and language parts).
1234
1235 Also, whereas % values were decoded in all parameter continuations, they are
1236 now only decoded in encoded parameter parts.
1237
Ronald Oussoren3075e162006-07-25 20:28:55 +00001238- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1239
1240- Bug #1517996: IDLE now longer shows the default Tk menu when a
1241 path browser, class browser or debugger is the frontmost window on MacOS X
1242
Barry Warsaw00decd72006-07-27 23:43:15 +00001243- Patch #1520294: Support for getset and member descriptors in types.py,
1244 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1245 of an object against these built-in types and more importantly, for getting
1246 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001249Extension Modules
1250-----------------
1251
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001252- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1253 a socket operation on a socket with a timeout, the exception will be
1254 caught correctly. Previously, the exception was not caught.
1255
Thomas Heller1393d6a2006-07-28 21:43:20 +00001256- Patch #1529514: The _ctypes extension is now compiled on more
1257 openbsd target platforms.
1258
Tim Peters9cab5932006-07-28 00:30:00 +00001259- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1260 a memory leak, affecting pickles and deep copies.
1261
Tim Petersbc24eee2006-07-27 01:14:53 +00001262- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001263 Paul Eggert.
1264
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001265- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1266
Thomas Hellerce049a02006-07-14 17:51:14 +00001267- Patch #1521817: Index range checking on ctypes arrays containing
1268 exactly one element enabled again. This allows iterating over these
1269 arrays, without the need to check the array size before.
1270
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001271- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001272 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001273 /dev/null in certain cases; this is now fixed.
1274
Thomas Heller47d7a062006-07-12 08:43:47 +00001275- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1276 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001277
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001278- Because of a misspelled preprocessor symbol, ctypes was always
1279 compiled without thread support; this is now fixed.
1280
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001281- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1282 methods now allow their database parameter to be None as the
1283 sleepycat API allows.
1284
Matt Flemingec926502006-07-28 11:27:27 +00001285- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1286 bluetooth API compared with Linux and FreeBSD.
1287
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001288Tests
1289-----
1290
1291- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1292 how long the test file should take to play. Now accepts taking 2.93 secs
1293 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1294
Georg Brandl4793aa32006-07-28 18:31:39 +00001295- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1296 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1297 run via ``regrtest.py``. Now they do.

1303
Ronald Oussoren26cad082006-08-01 21:00:57 +00001304Mac
1305---
1306
1307- PythonLauncher now works correctly when the path to the script contains
1308 characters that are treated specially by the shell (such as quotes).
1309
1310- Bug #1527397: PythonLauncher now launches scripts with the working directory
1311 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001312 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001313 expect.

1322-----------------
1323
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001324- Bug #1441486: The literal representation of -(sys.maxint - 1)
1325 again evaluates to a int object, not a long.
1326
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001327- Bug #1501934: The scope of global variables that are locally assigned
1328 using augmented assignment is now correctly determined.
1329
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001330- Bug #927248: Recursive method-wrapper objects can now safely
1331 be released.
1332
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001333- Bug #1417699: Reject locale-specific decimal point in float()
1334 and atof().
1335
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001336- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1337 omit a default "error" argument for NULL pointer. This allows
1338 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001339
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001340- Bug #1519018: 'as' is now validated properly in import statements.
1341
Neal Norwitz28746ab2006-07-09 22:14:42 +00001342- On 64 bit systems, int literals that use less than 64 bits are
1343 now ints rather than longs.
1344
Neal Norwitzed657552006-07-10 00:04:44 +00001345- Bug #1512814, Fix incorrect lineno's when code at module scope
1346 started after line 256.
1347
Tim Peters32a83612006-07-10 21:08:24 +00001348- New function ``sys._current_frames()`` returns a dict mapping thread
1349 id to topmost thread stack frame. This is for expert use, and is
1350 especially useful for debugging application deadlocks. The functionality
1351 was previously available in Fazal Majid's ``threadframe`` extension
1352 module, but it wasn't possible to do this in a wholly threadsafe way from
1353 an extension.

Martin v. Löwis77621582006-07-30 13:27:31 +00001358- Bug #1257728: Mention Cygwin in distutils error message about a missing
1359 VS 2003.
1360
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001361- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1362

Martin v. Löwis8d656812006-07-10 07:23:48 +00001364 environment variable to be set in order to the SDK environment
1365 for finding the compiler, include files, etc.

1370
Thomas Woutersadd19112006-07-05 11:03:49 +00001371- string.Template() now correctly handles tuple-values. Previously,
1372 multi-value tuples would raise an exception and single-value tuples would
1373 be treated as the value they contain, instead.
1374
Martin v. Löwisede77f52006-07-03 13:01:35 +00001375- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1376 even if some data are received.
1377
Martin v. Löwis45482392006-07-03 12:28:58 +00001378- Bug #1267547: Put proper recursive setup.py call into the
1379 spec file generated by bdist_rpm.
1380
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001381- Bug #1514693: Update turtle's heading when switching between
1382 degrees and radians.
1383
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001384- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001385 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001386
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001387- Bug #1514703: Only setup canvas window in turtle when the canvas
1388 is created.
1389
Martin v. Löwis7596e832006-07-01 15:33:37 +00001390- Bug #1513223: .close() of a _socketobj now releases the underlying
1391 socket again, which then gets closed as it becomes unreferenced.
1392
Fred Drake10497c82006-06-29 02:57:48 +00001393- Bug #1504333: Make sgmllib support angle brackets in quoted
1394 attribute values.
1395
1396- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1397 sgmllib ('[' and ']' were not accepted).
1398
Georg Brandl1be63af2006-06-28 20:23:25 +00001399- Fix a bug in the turtle module's end_fill function.
1400
Brett Cannon53ab5b72006-06-22 16:49:14 +00001401- Bug #1510580: The 'warnings' module improperly required that a Warning
1402 category be either a types.ClassType and a subclass of Warning. The proper
1403 check is just that it is a subclass with Warning as the documentation states.
1404
Georg Brandlad29e632006-06-21 17:45:17 +00001405- The compiler module now correctly compiles the new try-except-finally
1406 statement (bug #1509132).
1407
Neal Norwitz60373cd2006-06-22 06:30:50 +00001408- The wsgiref package is now installed properly on Unix.
1409
Vinay Sajip28e57612006-07-01 10:45:20 +00001410- A bug was fixed in logging.config.fileConfig() which caused a crash on
1411 shutdown when fileConfig() was called multiple times.
1412
Gerhard Häring762fbd32006-07-02 17:48:30 +00001413- The sqlite3 module did cut off data from the SQLite database at the first
1414 null character before sending it to a custom converter. This has been fixed
1415 now.

1418-----------------
1419
Tim Peters112aad32006-07-19 00:03:19 +00001420- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1421 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1422 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001423
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001424- Assigning None to pointer type fields in ctypes structures possible
1425 overwrote the wrong fields, this is fixed now.
1426
1427- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1428 on non-Windows platforms.
1429
1430- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1431 integer or long, without range checking.
1432
1433- Patch #1517790: It is now possible to use custom objects in the ctypes
1434 foreign function argtypes sequence as long as they provide a from_param
1435 method, no longer is it required that the object is a ctypes type.
1436
1437- The '_ctypes' extension module now works when Python is configured
1438 with the --without-threads option.
1439
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001440- Bug #1513646: os.access on Windows now correctly determines write
1441 access, again.
1442
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001443- Bug #1512695: cPickle.loads could crash if it was interrupted with
1444 a KeyboardInterrupt.

Neal Norwitza12aa882006-07-06 06:45:08 +00001446- Bug #1296433: parsing XML with a non-default encoding and
1447 a CharacterDataHandler could crash the interpreter in pyexpat.
1448
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001449- Patch #1516912: improve Modules support for OpenVMS.

1455
Tim Peters32a83612006-07-10 21:08:24 +00001456- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001457 Previously, the slight difference could cause compilation errors of the
1458 'zlib' module on systems with more than one version of zlib.
1459
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001460- The MSI compileall step was fixed to also support a TARGETDIR
1461 with spaces in it.
1462
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001463- Bug #1517388: sqlite3.dll is now installed on Windows independent

Anthony Baxter51bcb682006-04-05 14:51:42 +00001490
1491Core and builtins
1492-----------------
1493
Georg Brandla56b9152006-06-19 06:35:54 +00001494- Patch #1507676: Error messages returned by invalid abstract object operations
1495 (such as iterating over an integer) have been improved and now include the
1496 type of the offending object to help with debugging.
1497
Brett Cannonea3912b2006-06-13 21:46:41 +00001498- Bug #992017: A classic class that defined a __coerce__() method that returned
1499 its arguments swapped would infinitely recurse and segfault the interpreter.
1500
Neal Norwitz909eb122006-06-12 02:13:21 +00001501- Fix the socket tests so they can be run concurrently.
1502
Neal Norwitzb9845e72006-06-12 02:11:18 +00001503- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001504 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001505
Brett Cannon22565aa2006-06-09 22:31:23 +00001506- Bug #532646: object.__call__() will continue looking for the __call__
1507 attribute on objects until one without one is found. This leads to recursion
1508 when you take a class and set its __call__ attribute to an instance of the
1509 class. Originally fixed for classic classes, but this fix is for new-style.
1510 Removes the infinite_rec_3 crasher.
1511
Georg Brandl24250812006-06-09 18:45:48 +00001512- The string and unicode methods startswith() and endswith() now accept
1513 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1514
Brett Cannonde3b0522006-06-08 17:00:45 +00001515- Buffer objects, at the C level, never used the char buffer
1516 implementation even when the char buffer for the wrapped object was
1517 explicitly requested (originally returned the read or write buffer).
1518 Now a TypeError is raised if the char buffer is not present but is
1519 requested.
1520
Georg Brandlddbaa662006-06-04 21:56:52 +00001521- Patch #1346214: Statements like "if 0: suite" are now again optimized
1522 away like they were in Python 2.4.
1523
Georg Brandlb7c8f542006-05-27 12:30:25 +00001524- Builtin exceptions are now full-blown new-style classes instead of
1525 instances pretending to be classes, which speeds up exception handling
1526 by about 80% in comparison to 2.5a2.
1527
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001528- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1529 Unicode 4.1.
1530
Georg Brandlf4ef1162006-05-26 18:03:31 +00001531- Patch #921466: sys.path_importer_cache is now used to cache valid and
1532 invalid file paths for the built-in import machinery which leads to
1533 fewer open calls on startup.
1534
Tim Peters696cf432006-05-24 21:10:40 +00001535- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1536 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1537 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1538 the number of input digits (it was and remains linear-time for bases
1539 2, 4, 8, 16 and 32).
1540
Tim Petersb713ec22006-05-23 18:45:30 +00001541- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1542 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1543 an integer close to ``sys.maxint``. This was repaired by patch
1544 #1335972, which also gives a nice speedup.
1545
Richard Jonescebbefc2006-05-23 18:28:17 +00001546- Patch #1337051: reduced size of frame objects.
1547
1548- PyErr_NewException now accepts a tuple of base classes as its
1549 "base" parameter.
1550
Richard Jones7c88dcc2006-05-23 10:37:38 +00001551- Patch #876206: function call speedup by retaining allocated frame
1552 objects.
1553
Georg Brandl7b90e162006-05-18 07:01:27 +00001554- Bug #1462152: file() now checks more thoroughly for invalid mode
1555 strings and removes a possible "U" before passing the mode to the
1556 C library function.
1557
Neal Norwitz1004a532006-05-15 07:17:23 +00001558- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1559
Neal Norwitz373f0a72006-05-15 07:04:36 +00001560- Bug #1487966: Fix SystemError with conditional expression in assignment
1561
Martin v. Löwis879768d2006-05-11 13:28:43 +00001562- WindowsError now has two error code attributes: errno, which carries
1563 the error values from errno.h, and winerror, which carries the error
1564 values from winerror.h. Previous versions put the winerror.h values
1565 (from GetLastError()) into the errno attribute.
1566
Martin v. Löwis77736712006-05-04 05:51:03 +00001567- Patch #1475845: Raise IndentationError for unexpected indent.
1568
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001569- Patch #1479181: split open() and file() from being aliases for each other.
1570
Tim Peters44bd9862006-06-01 13:49:23 +00001571- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1572 methods were always silently ignored by dictionaries when comparing keys.
1573 They are now passed through (except when using the C API function
1574 ``PyDict_GetItem()``, whose semantics did not change).
1575
1576- Bug #1456209: In some obscure cases it was possible for a class with a
1577 custom ``__eq__()`` method to confuse dict internals when class instances
1578 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1579 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001581Extension Modules
1582-----------------
1583
Trent Mick960a3f82006-06-28 20:30:41 +00001584- Bug #1295808: expat symbols should be namespaced in pyexpat
1585
1586- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1587
Brett Cannon6ee7d012006-06-08 16:23:04 +00001588- Change binascii.hexlify to accept a read-only buffer instead of only a char
1589 buffer and actually follow its documentation.
1590
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001591- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1592
Nick Coghlanc649ec52006-05-29 12:43:05 +00001593- Patch #1478788 (modified version): The functional extension module has
1594 been renamed to _functools and a functools Python wrapper module added.
1595 This provides a home for additional function related utilities that are
1596 not specifically about functional programming. See PEP 309.
1597
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001598- Patch #1493701: performance enhancements for struct module.
1599
Georg Brandl378d5922006-05-17 14:26:50 +00001600- Patch #1490224: time.altzone is now set correctly on Cygwin.
1601
Georg Brandl8d3342b2006-05-16 07:38:27 +00001602- Patch #1435422: zlib's compress and decompress objects now have a
1603 copy() method.
1604
Andrew MacIntyre92913322006-06-13 15:04:24 +00001605- Patch #1454481: thread stack size is now tunable at runtime for thread
1606 enabled builds on Windows and systems with Posix threads support.
1607
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001608- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1609 (up to the system limit of 32K characters).
1610
1611- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1612 As a result, these functions now raise WindowsError instead of OSError.
1613
Tim Peters7a822da2006-05-25 21:50:17 +00001614- ``time.clock()`` on Win64 should use the high-performance Windows
1615 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1616 Windows platforms).
1617
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001618- Calling Tk_Init twice is refused if the first call failed as that
1619 may deadlock.
1620
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001621- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1622 accept it without potentially using an uninitialized pointer.
1623
1624- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1625 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1626 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001627
Gregory P. Smith372b5832006-06-05 18:48:21 +00001628- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001629 [pybsddb project SF patch number 1466734]
1630
Gregory P. Smith372b5832006-06-05 18:48:21 +00001631- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1632 parameter is supplied. [SF pybsddb bug #1477863]
1633
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001634- bsddb: the __len__ method of a DB object has been fixed to return correct
1635 results. It could previously incorrectly return 0 in some cases.
1636 Fixes SF bug 1493322 (pybsddb bug 1184012).
1637
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001638- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1639 aborts the db transaction safely when a modifier callback fails.
1640 Fixes SF python patch/bug #1408584.
1641
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001642- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001643 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001644 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1645 database calls that would previously deadlock. [SF python bug #775414]
1646
Vinay Sajip28e57612006-07-01 10:45:20 +00001647- Patch #1446489: add support for the ZIP64 extensions to zipfile.

1654
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001655- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1656 functions.
1657
Martin v. Löwis3798da02006-06-17 18:44:27 +00001658- Patch #812986: Update turtle output even if not tracing.
1659
Vinay Sajip28e57612006-07-01 10:45:20 +00001660- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001661 Tkinter.BaseWidget.
1662
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001663- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1664
Martin v. Löwis337487e2006-06-17 09:15:14 +00001665- Patch #763580: Add name and value arguments to Tkinter variable
1666 classes.
1667
Georg Brandl83cc0d02006-06-14 08:50:03 +00001668- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1669 mime.types file for determining MIME types.
1670
Georg Brandl2605ca82006-06-14 06:08:31 +00001671- Bug #1339007: Shelf objects now don't raise an exception in their
1672 __del__ method when initialization failed.
1673
Martin v. Löwisd8251432006-06-14 05:21:04 +00001674- Patch #1455898: The MBCS codec now supports the incremental mode for
1675 double-byte encodings.
1676
Tim Peters43898b42006-06-14 04:09:25 +00001677- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1678 guarantee that adjacent triples in the return list always describe
1679 non-adjacent blocks. Previously, a pair of matching blocks could end
1680 up being described by multiple adjacent triples that formed a partition
1681 of the matching pair.
1682
Greg Ward0e0c9f42006-06-11 16:24:11 +00001683- Bug #1498146: fix optparse to handle Unicode strings in option help,
1684 description, and epilog.
1685
Greg Wardd1c797e2006-06-11 14:42:41 +00001686- Bug #1366250: minor optparse documentation error.
1687
Greg Ward7f547402006-06-11 00:40:49 +00001688- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1689 clarify docs.
1690
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001691- The wsgiref package has been added to the standard library.
1692
Nick Coghlan676725d2006-06-08 13:54:49 +00001693- The functions update_wrapper() and wraps() have been added to the functools
1694 module. These make it easier to copy relevant metadata from the original
1695 function when writing wrapper functions.
1696
Tim Petersd6a9eef2006-06-05 01:48:21 +00001697- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1698 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001699
Martin v. Löwis3f767792006-06-04 19:36:28 +00001700- Patch #1359618: Speed up charmap encoder by using a trie structure
1701 for lookup.
1702
Tim Petersd609b1a2006-06-02 23:22:51 +00001703- The functions in the ``pprint`` module now sort dictionaries by key
1704 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1705 if and only if its display required more than one line, although that
1706 wasn't documented. The new behavior increases predictability; e.g.,
1707 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1708
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001709- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1710 (thanks for J. J. Lee).
1711
Georg Brandl2b330372006-05-28 20:23:12 +00001712- Patch #1496206: improve urllib2 handling of passwords with respect to
1713 default HTTP and HTTPS ports.
1714
George Yoshidaf3c65de2006-05-28 16:39:09 +00001715- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1716
Bob Ippolito7298f272006-05-23 18:43:47 +00001717- Patch #1281707: speed up gzip.readline.
1718
Georg Brandlb89316f2006-05-17 15:51:16 +00001719- Patch #1180296: Two new functions were added to the locale module:
1720 format_string() to get the effect of "format % items" but locale-aware,
1721 and currency() to format a monetary number with currency sign.
1722
Georg Brandle3a25832006-05-17 14:56:04 +00001723- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1724 and several features added, such as speed and geometry control.
1725
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001726- Patch #1488881: add support for external file objects in bz2 compressed
1727 tarfiles.
1728
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001729- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1730 stdout arguments, making it possible to redirect input and output
1731 for remote debugging.
1732
1733- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1734 a couple of issues, notably handling of long file names using the
1735 GNU LONGNAME extension.
1736
1737- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1738 new flag when ``name`` is already the name of an option flag.
1739
1740- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1741 package.
1742
1743- Patch #1472854: make the rlcompleter.Completer class usable on non-
1744 UNIX platforms.
1745
1746- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1747
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001748- Bug #1472827: correctly escape newlines and tabs in attribute values in

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001779What's New in Python 2.5 alpha 2?
1780=================================
1781
1782*Release date: 27-APR-2006*
1783
1784Core and builtins
1785-----------------
1786
Thomas Heller1b046642006-04-18 18:51:06 +00001787- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1788 by converting these apis from macros into exported functions again:
1789
1790 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1791 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1792 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1793 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1794 PyRun_String Py_CompileString
1795
Martin v. Löwis45294a92006-04-18 06:24:08 +00001796- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1797
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001798- All uses of PyStructSequence_InitType have been changed to initialize
1799 the type objects only once, even if the interpreter is initialized
1800 multiple times.
1801
Neal Norwitz61546162006-04-14 05:20:28 +00001802- Bug #1454485, array.array('u') could crash the interpreter. This was
1803 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1804 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1805
1806- Py_UNICODE is unsigned. It was always documented as unsigned, but
1807 due to a bug had a signed value in previous versions.
1808
Tim Peters3a5e8b12006-04-11 01:44:07 +00001809- Patch #837242: ``id()`` of any Python object always gives a positive
1810 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1811 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001812 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001813 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001814
Tim Peters3a5e8b12006-04-11 01:44:07 +00001815 def __hash__(self):
1816 return id(self) # WRONG
1817
1818 because a hash result must be a (short) Python int but it was always
1819 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001820 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001821 was always usable as a hash value before this patch. That's no longer
1822 necessarily so.
1823
1824- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001825 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001826 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001827 #1454844)
1828
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001829- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1830 involving generators that have paused outside of any ``try`` or ``with``
1831 blocks. (In 2.5a1, a paused generator that was part of a reference
1832 cycle could not be garbage collected, regardless of whether it was
1833 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001834
Anthony Baxter51bcb682006-04-05 14:51:42 +00001835Extension Modules

1837
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001838- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1839 is a macro.
1840
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001841- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1842 fails with an error condition.
1843
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001844- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1845
1846- Bug #1117761: bsddb.*open() no longer raises an exception when using
1847 the cachesize parameter.
1848
1849- Bug #1149413: bsddb.*open() no longer raises an exception when using
1850 a temporary db (file=None) with the 'n' flag to truncate on open.
1851
1852- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1853 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001854
Armin Rigoa9017c32006-04-19 11:50:27 +00001855- Patch #1062014: AF_UNIX sockets under Linux have a special
1856 abstract namespace that is now fully supported.
1857
Anthony Baxter51bcb682006-04-05 14:51:42 +00001858Library
1859-------
1860
Peter Astrand7d1d4362006-07-14 14:04:45 +00001861- Bug #1223937: subprocess.CalledProcessError reports the exit status
1862 of the process using the returncode attribute, instead of
1863 abusing errno.
1864
Tim Peters711bf302006-04-25 03:31:36 +00001865- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1866 a doctest to be skipped (the code is not run, and the expected output
1867 or exception is ignored).
1868
Nick Coghlanda2268f2006-04-24 04:37:15 +00001869- Fixed contextlib.nested to cope with exceptions being raised and
1870 caught inside exit handlers.
1871
Greg Wardab05edc2006-04-23 03:47:58 +00001872- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1873 hex, octal, or binary; add ``append_const`` action; keep going if
1874 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1875 added ``epilog`` for better help generation).
1876
Tim Peters21fbd572006-04-21 21:18:10 +00001877- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1878 called from a thread spawned as a side effect of importing a module.
1879
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001880- The pydoc module now supports documenting packages contained in
1881 .zip or .egg files.
1882
1883- The pkgutil module now has several new utility functions, such
1884 as ``walk_packages()`` to support working with packages that are either
1885 in the filesystem or zip files.
1886
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001887- The mailbox module can now modify and delete messages from
1888 mailboxes, in addition to simply reading them. Thanks to Gregory
1889 K. Johnson for writing the code, and to the 2005 Google Summer of
1890 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001891
Tim Petersc7605f22006-04-17 21:12:33 +00001892- The ``__del__`` method of class ``local`` in module ``_threading_local``
1893 returned before accomplishing any of its intended cleanup.
1894
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001895- Patch #790710: Add breakpoint command lists in pdb.
1896
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001897- Patch #1063914: Add Tkinter.Misc.clipboard_get().
1898
Martin v. Löwis4b501e62006-04-15 08:41:11 +00001899- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1900
Anthony Baxtere29002c2006-04-12 12:07:31 +00001901- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1902 Windows. Bug #1469163.
1903
Phillip J. Eby47032112006-04-11 01:07:43 +00001904- The warnings, linecache, inspect, traceback, site, and doctest modules
1905 were updated to work correctly with modules imported from zipfiles or
1906 via other PEP 302 __loader__ objects.
1907
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001908- Patch #1467770: Reduce usage of subprocess._active to processes which
1909 the application hasn't waited on.
1910
Martin v. Löwisb04dee92006-04-10 08:34:21 +00001911- Patch #1462222: Fix Tix.Grid.
1912
Neal Norwitza31bf182006-04-09 03:35:43 +00001913- Fix exception when doing glob.glob('anything*/')
1914
Skip Montanaro262fb922006-04-21 02:31:07 +00001915- The pstats.Stats class accepts an optional stream keyword argument to
1916 direct output to an alternate file-like object.
1917
Anthony Baxter51bcb682006-04-05 14:51:42 +00001918Build
1919-----
1920
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001921- The Makefile now has a reindent target, which runs reindent.py on
1922 the library.
1923
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001924- Patch #1470875: Building Python with MS Free Compiler
1925
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001926- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001927
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001928- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1929 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001930 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001931 CXX from --with-cxx-main, see description in README.
1932
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001933- Patch #1429775: Link extension modules with the shared libpython.
1934
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001935- Fixed a libffi build problem on MIPS systems.
1936
Tim Peters8931ff12006-05-13 23:28:20 +00001937- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1938 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1939 and "%zu" for unsigned integers of type ``size_t``.
1940
Anthony Baxter51bcb682006-04-05 14:51:42 +00001941Tests
1942-----
1943
Nick Coghlanda2268f2006-04-24 04:37:15 +00001944- test_contextlib now checks contextlib.nested can cope with exceptions
1945 being raised and caught inside exit handlers.
1946
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001947- test_cmd_line now checks operation of the -m and -c command switches
1948
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001949- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1950 it separately and by hand. It also wasn't cleaning up its changes to
1951 the current Decimal context.
1952
Thomas Woutersabd08882006-04-26 15:53:30 +00001953- regrtest.py now has a -M option to run tests that test the new limits of
1954 containers, on 64-bit architectures. Running these tests is only sensible
1955 on 64-bit machines with more than two gigabytes of memory. The argument
1956 passed is the maximum amount of memory for the tests to use.

1960
1961- Added the Python benchmark suite pybench to the Tools/ directory;
1962 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001964Documentation
1965-------------
1966
Tim Petersb06d28c2006-05-12 01:57:59 +00001967- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1968
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001969- PEP 343: Added Context Types section to the library reference
1970 and attempted to bring other PEP 343 related documentation into
1971 line with the implementation and/or python-dev discussions.
1972
Tim Peters8dc73d22006-04-24 02:03:16 +00001973- Bug #1337990: clarified that ``doctest`` does not support examples
1974 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001977What's New in Python 2.5 alpha 1?
1978=================================
1979
Anthony Baxterebed3f62006-04-03 15:03:44 +00001980*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001981
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001982Core and builtins
1983-----------------
1984
Nick Coghlan43832302006-04-23 17:04:07 +00001985- PEP 338: -m command line switch now delegates to runpy.run_module
1986 allowing it to support modules in packages and zipfiles
1987
Martin v. Löwisc661b882006-04-20 04:54:23 +00001988- On Windows, .DLL is not an accepted file name extension for
1989 extension modules anymore; extensions are only found if they
1990 end in .PYD.
1991
Martin v. Löwisea62d252006-04-03 10:56:49 +00001992- Bug #1421664: sys.stderr.encoding is now set to the same value as
1993 sys.stdout.encoding.
1994
Neal Norwitz92e212f2006-04-03 04:48:37 +00001995- __import__ accepts keyword arguments.
1996
Georg Brandlccadf842006-03-31 18:54:53 +00001997- Patch #1460496: round() now accepts keyword arguments.
1998
Anthony Baxter262c00a2006-03-30 10:53:17 +00001999- Fixed bug #1459029 - unicode reprs were double-escaped.
2000
Hye-Shik Changd478f342006-03-23 12:32:36 +00002001- Patch #1396919: The system scope threads are reenabled on FreeBSD
2002 5.4 and later versions.
2003
Neal Norwitze98ccf62006-03-23 05:39:47 +00002004- Bug #1115379: Compiling a Unicode string with an encoding declaration
2005 now gives a SyntaxError.
2006
Georg Brandlabd1ff82006-03-18 07:59:59 +00002007- Previously, Python code had no easy way to access the contents of a
2008 cell object. Now, a ``cell_contents`` attribute has been added
2009 (closes patch #1170323).
2010
Tim Peterscf79aac2006-03-16 01:14:46 +00002011- Patch #1123430: Python's small-object allocator now returns an arena to
2012 the system ``free()`` when all memory within an arena becomes unused
2013 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2014 freed. Some applications will see a drop in virtual memory size now,
2015 especially long-running applications that, from time to time, temporarily
2016 use a large number of small objects. Note that when Python returns an
2017 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002018 platform C library will in turn return that memory to the operating system.
2019 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002020 appears to be effective at least on Microsoft C and gcc-based systems.
2021 Thanks to Evan Jones for hard work and patience.
2022
Georg Brandl533ff6f2006-03-08 18:09:27 +00002023- Patch #1434038: property() now uses the getter's docstring if there is
2024 no "doc" argument given. This makes it possible to legitimately use
2025 property() as a decorator to produce a read-only property.
2026
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002027- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2028 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2029 of requiring an int or long in slicing and a few other contexts, enabling
2030 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2031
Neal Norwitz995acdf2006-03-07 05:01:00 +00002032- Fixed various bugs reported by Coverity's Prevent tool.
2033
Brett Cannonbf364092006-03-01 04:25:17 +00002034- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2035 new exception base class, BaseException, which has a new message attribute.
2036 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2037 Raising a string exception now raises a DeprecationWarning.
2038
Thomas Woutersfb609f42006-02-28 16:37:25 +00002039- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2040 explicitly relative, using 'from .module import name' to mean 'from the same
2041 package as this module is in. Imports without dots still default to the
2042 old relative-then-absolute, unless 'from __future__ import
2043 absolute_import' is used.
2044
Brett Cannona7446e32006-02-27 23:39:10 +00002045- Properly check if 'warnings' raises an exception (usually when a filter set
2046 to "error" is triggered) when raising a warning for raising string
2047 exceptions.
2048
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002049- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002050 The name was removed from Include/code.h.
2051
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002052- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002053
Guido van Rossum1968ad32006-02-25 22:38:04 +00002054- Patch 1433928:
2055 - The copy module now "copies" function objects (as atomic objects).
2056 - dict.__getitem__ now looks for a __missing__ hook before raising
2057 KeyError.
2058
Tim Peters84ef21c2006-02-28 20:39:06 +00002059- PEP 343: with statement implemented. Needs ``from __future__ import
2060 with_statement``. Use of 'with' as a variable will generate a warning.
2061 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002062 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002063 The following objects have __context__ methods:
2064 - The built-in file type.
2065 - The thread.LockType type.
2066 - The following types defined by the threading module:
2067 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2068 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002069
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002070- Fix the encodings package codec search function to only search
2071 inside its own package. Fixes problem reported in patch #1433198.
2072
2073 Note: Codec packages should implement and register their own
2074 codec search function. PEP 100 has the details.
2075
Tim Peters9ea89d22006-06-04 03:26:02 +00002076- PEP 353: Using ``Py_ssize_t`` as the index type.
2077
2078- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2079 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2080 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2081 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2082 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002083
Neal Norwitzfc76d632006-01-10 06:03:13 +00002084- Patch #1400181, fix unicode string formatting to not use the locale.
2085 This is how string objects work. u'%f' could use , instead of .
2086 for the decimal point. Now both strings and unicode always use periods.
2087
Neal Norwitz671b9e32006-01-09 07:07:12 +00002088- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2089 configure would break checking curses.h.
2090
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002091- Bug #959576: The pwd module is now builtin. This allows Python to be
2092 built on UNIX platforms without $HOME set.
2093
Neal Norwitzc10978f2005-12-19 06:07:16 +00002094- Bug #1072182, fix some potential problems if characters are signed.
2095
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002096- Bug #889500, fix line number on SyntaxWarning for global declarations.
2097
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002098- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2099
Neal Norwitze7214a12005-12-18 05:03:17 +00002100- Support for converting hex strings to floats no longer works.
2101 This was not portable. float('0x3') now raises a ValueError.
2102
Barry Warsaw2a38a862005-12-18 01:27:35 +00002103- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002104 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002105 is now displayed in interactive prompt banner.
2106
Georg Brandlfa166682005-12-17 21:45:17 +00002107- Implementation of PEP 341 - Unification of try/except and try/finally.
2108 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002109 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002110
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002111- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2112 now encodes backslash correctly.
2113
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002114- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2115
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002116- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002117 and long longs.
2118
Neal Norwitz67715f02005-11-09 06:59:35 +00002119- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002120 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002121 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002122
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002123- Replaced most Unicode charmap codecs with new ones using the
2124 new Unicode translate string feature in the builtin charmap
2125 codec; the codecs were created from the mapping tables available
2126 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2127 encodings now include a mapping for the Apple logo)
2128
Tim Peterse3547fd2005-12-16 23:13:57 +00002129- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002130
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002131- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002132
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002133- A new AST parser implementation was completed. The abstract
2134 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002135 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002136
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002137- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002138 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2139
Neal Norwitz708e51a2005-10-03 04:48:15 +00002140- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2141
Neal Norwitz11bd1192005-10-03 00:54:56 +00002142- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2143 Provide a warning when a directory is passed on the command line.
2144
Neal Norwitz40d37812005-10-02 01:48:49 +00002145- Fix segfault with invalid coding.
2146
2147- SF bug #772896: unknown encoding results in MemoryError.
2148
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002149- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002150 supported a __len__() method which evaluated to False when the iterator
2151 was empty.
2152
Guido van Rossum630db602005-09-20 18:49:54 +00002153- On 64-bit platforms, when __len__() returns a value that cannot be
2154 represented as a C int, raise OverflowError.
2155
Skip Montanarof8948ca2005-09-19 03:54:46 +00002156- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002157 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002158
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002159- SF bug #893549: parsing keyword arguments was broken with a few format
2160 codes.
2161
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002162- Changes donated by Elemental Security to make it work on AIX 5.3
2163 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2164 bug #105470: test_pwd fails on 64bit system (Opteron).
2165
Guido van Rossum539c6622005-09-14 17:49:54 +00002166- Changes donated by Elemental Security to make it work on HP-UX 11 on
2167 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2168
Georg Brandl4550b8d2005-08-26 06:43:52 +00002169- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002170 (fixes bug #1119418).
2171
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002172- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2173
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002174- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2175 exceptions that cause a function to exit.
2176
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002177- The implementation of set() and frozenset() was revised to use its
2178 own internal data structure. Memory consumption is reduced by 1/3
2179 and there are modest speed-ups as well. The API is unchanged.
2180
Tim Petersde7990b2005-07-17 23:45:23 +00002181- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2182
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002183- SF bug #1229429: PyObject_CallMethod failed to decrement some
2184 reference counts in some error exit cases.
2185
Tim Petersecc6e6a2005-07-10 22:30:55 +00002186- SF bug #1185883: Python's small-object memory allocator took over
2187 a block managed by the platform C library whenever a realloc specified
2188 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002189 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002190 portable way to copy data from the C-managed block into Python's
2191 small-object space without risking a memory fault. Python's small-object
2192 realloc now leaves such blocks under the control of the platform C
2193 realloc.
2194
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002195- SF bug #1232517: An overflow error was not detected properly when
2196 attempting to convert a large float to an int in os.utime().
2197
Raymond Hettinger3296e692005-06-29 23:29:56 +00002198- SF bug #1224347: hex longs now print with lowercase letters just
2199 like their int counterparts.
2200
Michael W. Hudson188d4362005-06-20 16:52:57 +00002201- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2202 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2203 interpreter states; back out that fix and do a better job (see
2204 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2205 for a longer write-up of the problem).
2206
Michael W. Hudsondf888462005-06-03 14:41:55 +00002207- SF patch #1180995: marshal now uses a binary format by default when
2208 serializing floats.
2209
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002210- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2211 the routines that promise to produce IEEE 754 binary representations
2212 of floats now simply copy bytes around.
2213
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002214- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2215 278.
2216
Brett Cannonc3647ac2005-04-26 03:45:26 +00002217- patch #1109424: int, long, float, complex, and unicode now check for the
2218 proper magic slot for type conversions when subclassed. Previously the
2219 magic slot was ignored during conversion. Semantics now match the way
2220 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002221 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002222 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002223 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002224
Barry Warsawc8d907c2005-04-19 23:43:40 +00002225- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2226 NULL, now raise an AttributeError when attempting to set or delete the
2227 attribute. Previously a TypeError was raised, but this was inconsistent
2228 with the equivalent pure-Python implementation.
2229
Michael W. Hudson774479c2005-04-18 08:46:17 +00002230- It is now safe to call PyGILState_Release() before
2231 PyEval_InitThreads() (note that if there is reason to believe there
2232 are multiple threads around you still must call PyEval_InitThreads()
2233 before using the Python API; this fix is for extension modules that
2234 have no way of knowing if Python is multi-threaded yet).
2235
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002236- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2237 disabled caused a crash.
2238
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002239- Bug #1165306: instancemethod_new allowed the creation of a method
2240 with im_class == im_self == NULL, which caused a crash when called.
2241
Tim Petersecc6e6a2005-07-10 22:30:55 +00002242- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002243 fixes the crash seen in bug #1165761
2244
Raymond Hettinger96229b12005-03-11 06:49:40 +00002245- Added two new builtins, any() and all().
2246
Brett Cannon409d8f22005-03-05 06:47:57 +00002247- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002248 (e.g., ``class C(): pass`` is no longer a syntax error).
2249 Patch #1176012 added support to the 'parser' module and 'compiler' package
2250 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002251
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002252- Patch #1115086: Support PY_LONGLONG in structmember.
2253
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002254- Bug #1155938: new style classes did not check that __init__() was
2255 returning None.
2256
Tim Petersecc6e6a2005-07-10 22:30:55 +00002257- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002258 ('\') with a specific error message.
2259
Martin v. Löwisff232d72005-03-03 09:24:38 +00002260- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2261
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002262- Bug #1124295: the __name__ attribute of file objects was
2263 inadvertently made inaccessible in restricted mode.
2264
Tim Petersecc6e6a2005-07-10 22:30:55 +00002265- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002266 an ferror() call.
2267
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002268- min() and max() now support key= arguments with the same meaning as in
2269 list.sort().
2270
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002271- The peephole optimizer now performs simple constant folding in expressions:
2272 (2+3) --> (5).
2273
Raymond Hettingera422c342005-01-11 03:03:27 +00002274- set and frozenset objects can now be marshalled. SF #1098985.
2275
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002276- Bug #1077106: Poor argument checking could cause memory corruption
2277 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002278
Jeremy Hyltonab630502005-02-04 18:44:06 +00002279- The parser did not complain about future statements in illegal
2280 positions. It once again reports a syntax error if a future
2281 statement occurs after anything other than a doc string.
2282
Neil Schemenauercf52c072005-08-12 17:34:58 +00002283- Change the %s format specifier for str objects so that it returns a
2284 unicode instance if the argument is not an instance of basestring and
2285 calling __str__ on the argument returns a unicode instance.
2286
Tim Petersf4e69282006-02-27 17:15:31 +00002287- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2288 current thread state when the auto-GIL-state machinery knows about
2289 it (since the thread state is being deleted, continuing to remember it
2290 can't help, but can hurt if another thread happens to get created with
2291 the same thread id).
2292
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002293Extension Modules
2294-----------------
2295
Georg Brandl43f08a82006-03-31 18:01:16 +00002296- Patch #1380952: fix SSL objects timing out on consecutive read()s
2297
Neal Norwitz05a45592006-03-20 06:30:08 +00002298- Patch #1309579: wait3 and wait4 were added to the posix module.
2299
Anthony Baxterfa869072006-03-20 05:21:58 +00002300- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
2301 In addition, the existing ulaw code was updated.
2302
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002303- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00002304 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002305
Neal Norwitz10be10c2006-03-16 06:50:13 +00002306- Everything under lib-old was removed. This includes the following modules:
2307 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00002308 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00002309 util, whatsound, whrandom, zmod
2310
2311- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2312
2313- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002314 is deprecated. The undocumented re.engine variable no longer exists.
2315
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002316- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2317 SS2 (single-shift 2) escape sequences correctly.
2318
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002319- The unicodedata module was updated to the 4.1 version of the Unicode
2320 database. The 3.2 version is still available as unicodedata.db_3_2_0
2321 for applications that require this specific version (such as IDNA).
2322
Neal Norwitzb62c4332006-03-04 18:35:47 +00002323- The timing module is no longer built by default. It was deprecated

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002483- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2484 been renamed to have only a single underscore prefix. This was done to
2485 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002486
Nick Coghlan43832302006-04-23 17:04:07 +00002487- PEP 338: new module runpy defines a run_module function to support
2488 executing modules which provide access to source code or a code object
2489 via the PEP 302 import mechanisms.
2490
Anthony Baxter93f5b932006-04-03 08:05:07 +00002491- The email module's parsedate_tz function now sets the daylight savings

2499 in attribute values.
2500
Anthony Baxterc51ee692006-04-01 00:57:31 +00002501- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002502 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002503 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002504 module will not be built.
2505
Tim Petersc17976e2006-04-01 00:26:53 +00002506- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2507 aren't officially supported here, and trying to use them will probably
2508 raise an exception some day. But dicts have been allowed, and "mostly
2509 worked", so support for them won't go away without warning.
2510
Georg Brandl338ef7d2006-03-31 18:42:16 +00002511- Bug #1445068: getpass.getpass() can now be given an explicit stream
2512 argument to specify where to write the prompt.
2513

2529
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002530- email 4.0 package now integrated. This is largely the same as the email 3.0
2531 package that was included in Python 2.3, except that PEP 8 module names are
2532 now used (e.g. mail.message instead of email.Message). The MIME classes
2533 have been moved to a subpackage (e.g. email.mime.text instead of
2534 email.MIMEText). The old names are still supported for now. Several
2535 deprecated Message methods have been removed and lots of bugs have been
2536 fixed. More details can be found in the email package documentation.
2537
Walter Dörwald40108c92006-03-27 08:15:44 +00002538- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2539 (a subclass of tuple) that provides incremental decoders and encoders
2540 (a way to use stateful codecs without the stream API). Python functions
2541 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2542 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2543 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00002545- Patch #1359365: Calling next() on a closed StringIO.String object raises
2546 a ValueError instead of a StopIteration now (like file and cString.String do).
2547 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2548 called before (like file and StringIO.StringIO do).

2616
Neal Norwitz338e7862005-12-23 21:27:46 +00002617- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
2618 LoadError as documented, instead of IOError. For compatibility,
2619 LoadError subclasses IOError.
2620
Brett Cannon3cbd0382005-12-16 22:49:23 +00002621- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00002622 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2623 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2624 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2625 Ronald L. Rivest offered this advice for Python:
2626
2627 "The consensus of researchers in this area (at least as
2628 expressed at the NIST Hash Function Workshop 10/31/05),
2629 is that SHA-256 is a good choice for the time being, but
2630 that research should continue, and other alternatives may
2631 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002632
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002633- Added a subset of Fredrik Lundh's ElementTree package. Available

2726 Bug #1224621.
2727
Raymond Hettinger68c04532005-06-10 11:05:19 +00002728- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002729 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002730 the generate_tokens() function now accepts a callable argument that
2731 terminates by raising StopIteration.
2732
Georg Brandl9166e1a2005-06-04 09:20:03 +00002733- Bug #1196315: fix weakref.WeakValueDictionary constructor.

2750 instead of raising a TypeError when interacting with other types. This
2751 allows other classes to implement __radd__ style methods and have them
2752 work as expected.
2753
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002754- Bug #1163325: Decimal infinities failed to hash. Attempting to

Guido van Rossumd0641422005-02-03 15:01:24 +00002792- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2793 disables recursive traversal through instance attributes, which can
2794 be exploited in various ways.
2795
Tim Peterse3547fd2005-12-16 23:13:57 +00002796- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002797 flags on the HTTP listening socket.
2798

2808
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002809- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2810
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002811- Enhancements to the csv module:
2812
2813 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002814 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002815 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002816 + Dialect parameter parsing has been re-implemented to improve error
2817 reporting.
2818 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2819 dictates.
2820 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002821 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002822 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002823 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2824 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002825 + reader now allows \r characters to be quoted (previously it only allowed
2826 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002827 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002828 + Dialect classes passed to the module are no longer instantiated by
2829 the module before being parsed (the former validation scheme required
2830 this, but the mechanism was unreliable).
2831 + The dialect registry now contains instances of the internal
2832 C-coded dialect type, rather than references to python objects.
2833 + the internal c-coded dialect type is now immutable.
2834 + register_dialect now accepts the same keyword dialect specifications
2835 as the reader and writer, allowing the user to register dialects
2836 without first creating a dialect class.
2837 + a configurable limit to the size of parsed fields has been added -
2838 previously, an unmatched quote character could result in the entire
2839 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002840 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002841 the parser field size limit (returning the former limit). The initial
2842 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002843 + A line_num attribute has been added to the reader object, which tracks
2844 the number of lines read from the source iterator. This is not
2845 the same as the number of records returned, as records can span
2846 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002847 + reader and writer objects were not being registered with the cyclic-GC.
2848 This has been fixed.
2849
Brett Cannone6539c42005-01-08 02:43:53 +00002850- _DummyThread objects in the threading module now delete self.__block that is
2851 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2852 lock primitives tend to be limited in number and thus should not be wasted on
2853 a _DummyThread object. Fixes bug #1089632.
2854
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002855- The imghdr module now detects Exif files.
2856
Raymond Hettinger6065d322004-12-20 23:51:53 +00002857- StringIO.truncate() now correctly adjusts the size attribute.
2858 (Bug #951915).
2859
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002860- locale.py now uses an updated locale alias table (built using
2861 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2862 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002863 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002864
Raymond Hettinger3557f422004-12-07 12:02:02 +00002865- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2866
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002867- the pickle module no longer accepts the deprecated None option in the
2868 args tuple returned by __reduce__().
2869
Brett Cannon84667c02004-12-07 03:25:18 +00002870- optparse now optionally imports gettext. This allows its use in setup.py.
2871
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002872- the pickle module no longer uses the deprecated bin parameter.
2873
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002874- the shelve module no longer uses the deprecated binary parameter.
2875

2877
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002878- the filecmp module no longer uses the deprecated use_statcache argument.
2879
Raymond Hettinger664347b2004-12-04 21:21:53 +00002880- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2881 extended or overridden by subclasses. Formerly, the subclassed method would
2882 be ignored by the rest of the module. (Bug #1078905).
2883
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002884- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002885 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002886
Walter Dörwald36733692004-12-22 12:50:50 +00002887- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2888 once when a size argument is given. This prevents a buffer overflow in the
2889 tokenizer with very long source lines.
2890
Barry Warsaw538561e2006-01-01 21:48:54 +00002891- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2892 immediately after creating the object, without any intervening
2893 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002894
Skip Montanaro05885812005-01-16 20:48:27 +00002895- The reconvert.quote function can now emit triple-quoted strings. The
2896 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002897
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002898- ``UserString.MutableString`` now supports negative indices in
2899 ``__setitem__`` and ``__delitem__``
2900
Greg Ward40407942005-03-05 02:53:17 +00002901- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2902 correctly.
2903
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002904- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2905 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2906 character even if the user has passed a size parameter to get a proper
2907 line ending. Remove the special handling of a "\r\n" that has been split
2908 between two lines.
2909
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002910- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2911 about illegal code points. The codec now supports PEP 293 style error
2912 handlers.
2913
Walter Dörwald78a78b02005-09-01 12:04:29 +00002914- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002915 from the input stream, so that the output is a byte string in the correct
2916 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002917
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002918- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2919 considering it exactly like a '*'.
2920
Walter Dörwald007f8df2005-10-09 19:42:27 +00002921- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2922 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002923
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002924- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2925
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002926- Patch #1413711: Certain patterns of differences were making difflib
2927 touch the recursion limit.
2928
Walter Dörwald58917a62006-03-31 15:26:22 +00002929- Bug #947906: An object oriented interface has been added to the calendar
2930 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002931 called as a script (e.g. via ``python -mcalendar``). Localized month and
2932 weekday names can be ouput (even if an exotic encoding is used) using
2933 special classes that use unicode.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002935Build
2936-----
2937
Neal Norwitz602d3392006-03-31 08:21:40 +00002938- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2939 by using -mieee gcc option.
2940
Martin v. Löwis86d66262006-02-17 08:40:11 +00002941- Patch #1432345: Make python compile on DragonFly.
2942
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002943- Build support for Win64-AMD64 was added.
2944
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002945- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2946
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002947- Patch #881820: look for openpty and forkpty also in libbsd.
2948
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002949- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2950 The zlib module is now builtin on Windows.
2951
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002952- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2953
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002954- Bug #1189330: configure did not correctly determine the necessary
2955 value of LINKCC if python was built with GCC 4.0.
2956
Trent Mick8321b422005-07-26 02:29:21 +00002957- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2958 vulnerability in zlib 1.2.1 and 1.2.2.
2959
Brett Cannon08cd5982005-04-24 22:26:38 +00002960- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2961 flags that change binary compatibility. Changes were also made to
2962 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002963 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002964
Bob Ippolitoed233462005-03-29 13:47:59 +00002965- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2966 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2967 no longer exists). This configure patch makes things right.
2968
Martin v. Löwise2713be2005-03-08 15:03:08 +00002969- Bug #1158607: Build with --disable-unicode again.
2970
Brett Cannon46d96232005-02-16 00:07:19 +00002971- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2972 defined. Discovered as a result of not being able to build on OS X.
2973
Brett Cannon516592f2004-12-07 00:42:59 +00002974- setup.py now uses the directories specified in LDFLAGS using the -L option
2975 and in CPPFLAGS using the -I option for adding library and include
2976 directories, respectively, for compiling extension modules against. This has
2977 led to the core being compiled using the values in CPPFLAGS. It also removes
2978 the need for the special-casing of both DarwinPorts and Fink for darwin since
2979 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2980 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2981 Fink, ``-I/opt/local/include`` for DarwinPorts).
2982
Brett Cannon43802422005-02-10 20:48:03 +00002983- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2984 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2985 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2986 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002988C API
2989-----
2990
Tim Petersc9d78aa2006-03-26 23:27:58 +00002991- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2992 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2993 is obtained via the ``PyObject_`` family, it must be released via the
2994 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2995 always been officially true, but when Python's small-object allocator was
2996 introduced, an attempt was made to cater to a few extension modules
2997 discovered at the time that obtained memory via ``PyObject_New`` but
2998 released it via ``PyMem_DEL``. It's years later, and if such code still
2999 exists it will fail now (probably with segfaults, but calling wrong
3000 low-level memory management functions can yield many symptoms).
3001
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003002- Added a C API for set and frozenset objects.
3003
Raymond Hettinger66517482004-12-03 11:45:13 +00003004- Removed PyRange_New().
3005
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003006- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3007 mapping argument now. This string is used as a mapping table. Byte values
3008 greater than the length of the string and 0xFFFE are treated as undefined
3009 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003016
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00003017- Patch #1276356: New resource "urlfetch" is implemented. This enables
3018 even impatient people to run tests that require remote files.
