Guido van Rossumc69ac252006-08-10 18:09:25 +0000919What's New in Python 2.5 release candidate 1?
920=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000921
Anthony Baxterb4096662006-08-16 03:42:26 +0000922*Release date: 17-AUG-2006*
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000923
924Core and builtins
925-----------------
926
Neal Norwitz24b6f202006-09-05 04:43:56 +0000927- Fix infinite recursion when subclassing long and overriding __hash__.
928
929- Fix concatenation (+=) of long strings.
930
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000931- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000932 compared equal or unequal to a string and a UnicodeDecodeError
933 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000934
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000935 Instead, the equal (==) and unequal (!=) comparison operators will
936 now issue a UnicodeWarning and interpret the two objects as
937 unequal. The UnicodeWarning can be filtered as desired using
938 the warning framework, e.g. silenced completely, turned into an
939 exception, logged, etc.
940
941 Note that compare operators other than equal and unequal will still
942 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000943
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000944- Fix segfault when doing string formatting on subclasses of long.
945
946- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
947 with new-style classes.
948
949- Fix bug related to __len__ functions returning negative values with
950 classic classes.
951
952- Patch #1538606, Fix __index__() clipping. There were some problems
953 discovered with the API and how integers that didn't fit into Py_ssize_t
954 were handled. This patch attempts to provide enough alternatives
955 to effectively use __index__.
956
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000957- Bug #1536021: __hash__ may now return long int; the final hash
958 value is obtained by invoking hash on the long int.
959
Thomas Hellerab1049c2006-08-08 17:37:00 +0000960- Bug #1536786: buffer comparison could emit a RuntimeWarning.
961
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000962- Bug #1535165: fixed a segfault in input() and raw_input() when
963 sys.stdin is closed.
964
Thomas Heller74d36f02006-08-04 18:17:40 +0000965- On Windows, the PyErr_Warn function is now exported from
966 the Python dll again.
967
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000968- Bug #1191458: tracing over for loops now produces a line event
969 on each iteration. Fixing this problem required changing the .pyc
970 magic number. This means that .pyc files generated before 2.5c1
971 will be regenerated.
972
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000973- Bug #1333982: string/number constants were inappropriately stored
974 in the byte code and co_consts even if they were not used, ie
975 immediately popped off the stack.
976
Georg Brandle9462c72006-08-04 18:03:37 +0000977- Fixed a reference-counting problem in property().
978
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000979
980Library
981-------
982
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000983- Fix a bug in the ``compiler`` package that caused invalid code to be
984 generated for generator expressions.
985
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000986- The distutils version has been changed to 2.5.0. The change to
987 keep it programmatically in sync with the Python version running
988 the code (introduced in 2.5b3) has been reverted. It will continue
989 to be maintained manually as static string literal.
990
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000991- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000992 and this cannot be converted to the required C type, an exception is
993 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000994 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000995
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000996- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000997 an exception.
998
Tim Peterscbdd3502006-09-05 01:47:53 +0000999- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001000 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001001 workarounds for clocks with low resolution, to stop the code yielding
1002 duplicate UUIDs.
1003
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001004- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1005 before raising SystemExit, allowing IDLE to honor quit() and exit().
1006
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001007- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1008
Georg Brandl7a1af772006-08-14 21:55:28 +00001009- Patch #1536071: trace.py should now find the full module name of a
1010 file correctly even on Windows.
1011
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001012- logging's atexit hook now runs even if the rest of the module has
1013 already been cleaned up.
1014
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001015- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001016
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001017- Bug #1531405, format_exception no longer raises an exception if
1018 str(exception) raised an exception.
1019
Neil Schemenauer06ded092006-08-04 16:20:30 +00001020- Fix a bug in the ``compiler`` package that caused invalid code to be
1021 generated for nested functions.
1022
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001023

Georg Brandl3335a7a2006-08-14 21:42:55 +00001031- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
1032 raises the correct exceptions.
1033
Thomas Heller1ce433e2006-08-14 16:20:04 +00001034- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1035 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1036
Thomas Heller86720042006-08-14 11:17:48 +00001037- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1038 uses the _as_parameter_ attribute when objects are passed to foreign
1039 function calls. The ctypes version number was changed to 1.0.1.
1040
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001041- Bug #1530559, struct.pack raises TypeError where it used to convert.
1042 Passing float arguments to struct.pack when integers are expected
1043 now triggers a DeprecationWarning.
1044
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001045

1081
Tim Peters4643c2f2006-08-10 22:45:34 +00001082- Bug #1069160. Internal correctness changes were made to
1083 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1084 the documentation was changed to state that the return value
1085 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001088What's New in Python 2.5 beta 3?
1089================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001090
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001091*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001092
1093Core and builtins
1094-----------------
1095
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001096- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001097 returned a long (see PEP 353).
1098
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001099- Bug #1515471: string.replace() accepts character buffers again.
1100
Neal Norwitz07aadb12006-07-30 06:55:48 +00001101- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1102 This provides the proper warning for struct.pack().
1103 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1104
Neal Norwitz0d62a062006-07-30 06:53:31 +00001105- Patch #1531113: Fix augmented assignment with yield expressions.
1106 Also fix a SystemError when trying to assign to yield expressions.
1107
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001108- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1109 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1110 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1111 excessive filesystem operations during imports.
1112
Tim Petersbc24eee2006-07-27 01:14:53 +00001113- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1114 operations on signed longs that are formally undefined by C.
1115 Unfortunately, at least one compiler now cares about that, so complicated
1116 the code to make that compiler happy again.
1117
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001118- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1119
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001120- Patch #1232023: Stop including current directory in search
1121 path on Windows.
1122
Neal Norwitze1fdb322006-07-21 05:32:28 +00001123- Fix some potential crashes found with failmalloc.
1124
Neal Norwitze7563102006-07-17 01:00:16 +00001125- Fix warnings reported by Klocwork's static analysis tool.
1126
Neal Norwitz84be93b2006-07-16 01:50:38 +00001127- Bug #1512814, Fix incorrect lineno's when code within a function
1128 had more than 255 blank lines.
1129
Georg Brandl9dceedb2006-07-12 15:31:17 +00001130- Patch #1521179: Python now accepts the standard options ``--help`` and
1131 ``--version`` as well as ``/?`` on Windows.
1132
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001133- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001134 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001135 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001136
Tim Peters112aad32006-07-19 00:03:19 +00001137- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001138 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001139 new ``sys._current_frames()`` returns a dictionary with one entry,
1140 mapping the faux "thread id" 0 to the current frame.
1141
Ronald Oussoren3075e162006-07-25 20:28:55 +00001142- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001143
Ronald Oussoren3075e162006-07-25 20:28:55 +00001144
Neal Norwitza1f10902006-07-12 07:28:29 +00001145Library
1146-------
1147
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001148- Correction of patch #1455898: In the mbcs decoder, set final=False
1149 for stream decoder, but final=True for the decode function.
1150
Georg Brandl07fec3a2006-08-01 18:49:24 +00001151- os.urandom no longer masks unrelated exceptions like SystemExit or
1152 KeyboardInterrupt.
1153
Tim Peters4643c2f2006-08-10 22:45:34 +00001154- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001155 shutil.copytree on Windows
1156
Georg Brandle34ac7c2006-07-30 11:07:23 +00001157- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1158 refers to file descriptors, not file objects.
1159
Tim Peterscbdd3502006-09-05 01:47:53 +00001160- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001161 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001162 #1513611, and probably others.
1163
Georg Brandledd9b0d2006-07-29 09:33:26 +00001164- Bug #1441397: The compiler module now recognizes module and function
1165 docstrings correctly as it did in Python 2.4.
1166
Tim Peters6f681472006-07-27 23:44:37 +00001167- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1168 lost that tests are sorted by name before being run. This rarely
1169 matters for well-written tests, but can create baffling symptoms if
1170 side effects from one test to the next affect outcomes. ``DocTestFinder``
1171 has been changed to sort the list of tests it returns.
1172
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001173- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001174 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001175
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001176- Bug #978833: Really close underlying socket in _socketobject.close.
1177
Georg Brandldb232dc2006-08-20 13:15:43 +00001178- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1179 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001180
Georg Brandlcf0c1722006-07-26 07:23:32 +00001181- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1182 to recursive calls and call it with the failing package name.
1183
Martin v. Löwis0b483032006-07-25 09:53:12 +00001184- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1185
Georg Brandlc13c34c2006-07-24 14:09:56 +00001186- Patch #1515343: Fix printing of deprecated string exceptions with a
1187 value in the traceback module.
1188
Greg Ward48fae7a2006-07-23 16:05:51 +00001189- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1190
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001191- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1192
Brett Cannoncaebe222006-07-18 04:41:36 +00001193- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1194 argument tuple. For arguments where zero is illegal, the value is forced to
1195 the minimum value that is correct. This is to support an undocumented but
1196 common way people used to fill in inconsequential information in the time
1197 tuple pre-2.4.
1198
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001199- Patch #1220874: Update the binhex module for Mach-O.
1200
Barry Warsawb110bad2006-07-21 14:51:07 +00001201- The email package has improved RFC 2231 support, specifically for
1202 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1203 (name*0=<blah>) parameter continuations. This may change the types of
1204 values returned from email.message.Message.get_param() and friends.
1205 Specifically in some cases where non-encoded continuations were used,
1206 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1207 will just return the string (since non-encoded continuations don't have
1208 charset and language parts).
1209
1210 Also, whereas % values were decoded in all parameter continuations, they are
1211 now only decoded in encoded parameter parts.
1212
Ronald Oussoren3075e162006-07-25 20:28:55 +00001213- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1214
1215- Bug #1517996: IDLE now longer shows the default Tk menu when a
1216 path browser, class browser or debugger is the frontmost window on MacOS X
1217
Barry Warsaw00decd72006-07-27 23:43:15 +00001218- Patch #1520294: Support for getset and member descriptors in types.py,
1219 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1220 of an object against these built-in types and more importantly, for getting
1221 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001224Extension Modules
1225-----------------
1226
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001227- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1228 a socket operation on a socket with a timeout, the exception will be
1229 caught correctly. Previously, the exception was not caught.
1230
Thomas Heller1393d6a2006-07-28 21:43:20 +00001231- Patch #1529514: The _ctypes extension is now compiled on more
1232 openbsd target platforms.
1233
Tim Peters9cab5932006-07-28 00:30:00 +00001234- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1235 a memory leak, affecting pickles and deep copies.
1236
Tim Petersbc24eee2006-07-27 01:14:53 +00001237- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001238 Paul Eggert.
1239
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001240- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1241
Thomas Hellerce049a02006-07-14 17:51:14 +00001242- Patch #1521817: Index range checking on ctypes arrays containing
1243 exactly one element enabled again. This allows iterating over these
1244 arrays, without the need to check the array size before.
1245
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001246- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001247 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001248 /dev/null in certain cases; this is now fixed.
1249
Thomas Heller47d7a062006-07-12 08:43:47 +00001250- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1251 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001252
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001253- Because of a misspelled preprocessor symbol, ctypes was always
1254 compiled without thread support; this is now fixed.
1255
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001256- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1257 methods now allow their database parameter to be None as the
1258 sleepycat API allows.
1259
Matt Flemingec926502006-07-28 11:27:27 +00001260- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1261 bluetooth API compared with Linux and FreeBSD.
1262
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001263Tests
1264-----
1265
1266- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1267 how long the test file should take to play. Now accepts taking 2.93 secs
1268 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1269
Georg Brandl4793aa32006-07-28 18:31:39 +00001270- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1271 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1272 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +00001273
Martin v. Löwis0907f4d2006-07-30 14:09:47 +00001274Build
1275-----
1276
1277- Bug #1439538: Drop usage of test -e in configure as it is not portable.
1278
Ronald Oussoren26cad082006-08-01 21:00:57 +00001279Mac
1280---
1281
1282- PythonLauncher now works correctly when the path to the script contains
1283 characters that are treated specially by the shell (such as quotes).
1284
1285- Bug #1527397: PythonLauncher now launches scripts with the working directory
1286 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001287 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001288 expect.

1297-----------------
1298
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001299- Bug #1441486: The literal representation of -(sys.maxint - 1)
1300 again evaluates to a int object, not a long.
1301
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001302- Bug #1501934: The scope of global variables that are locally assigned
1303 using augmented assignment is now correctly determined.
1304
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001305- Bug #927248: Recursive method-wrapper objects can now safely
1306 be released.
1307
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001308- Bug #1417699: Reject locale-specific decimal point in float()
1309 and atof().
1310
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001311- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1312 omit a default "error" argument for NULL pointer. This allows
1313 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001314
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001315- Bug #1519018: 'as' is now validated properly in import statements.
1316
Neal Norwitz28746ab2006-07-09 22:14:42 +00001317- On 64 bit systems, int literals that use less than 64 bits are
1318 now ints rather than longs.
1319
Neal Norwitzed657552006-07-10 00:04:44 +00001320- Bug #1512814, Fix incorrect lineno's when code at module scope
1321 started after line 256.
1322
Tim Peters32a83612006-07-10 21:08:24 +00001323- New function ``sys._current_frames()`` returns a dict mapping thread
1324 id to topmost thread stack frame. This is for expert use, and is
1325 especially useful for debugging application deadlocks. The functionality
1326 was previously available in Fazal Majid's ``threadframe`` extension
1327 module, but it wasn't possible to do this in a wholly threadsafe way from
1328 an extension.
1329

1345
Thomas Woutersadd19112006-07-05 11:03:49 +00001346- string.Template() now correctly handles tuple-values. Previously,
1347 multi-value tuples would raise an exception and single-value tuples would
1348 be treated as the value they contain, instead.
1349
Martin v. Löwisede77f52006-07-03 13:01:35 +00001350- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1352
Martin v. Löwis45482392006-07-03 12:28:58 +00001353- Bug #1267547: Put proper recursive setup.py call into the
1354 spec file generated by bdist_rpm.
1355
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001356- Bug #1514693: Update turtle's heading when switching between
1357 degrees and radians.
1358
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001359- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001360 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001361
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001362- Bug #1514703: Only setup canvas window in turtle when the canvas
1363 is created.
1364
Martin v. Löwis7596e832006-07-01 15:33:37 +00001365- Bug #1513223: .close() of a _socketobj now releases the underlying
1366 socket again, which then gets closed as it becomes unreferenced.
1367
Fred Drake10497c82006-06-29 02:57:48 +00001368- Bug #1504333: Make sgmllib support angle brackets in quoted
1369 attribute values.
1370
1371- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1372 sgmllib ('[' and ']' were not accepted).
1373
Georg Brandl1be63af2006-06-28 20:23:25 +00001374- Fix a bug in the turtle module's end_fill function.
1375
Brett Cannon53ab5b72006-06-22 16:49:14 +00001376- Bug #1510580: The 'warnings' module improperly required that a Warning
1377 category be either a types.ClassType and a subclass of Warning. The proper
1378 check is just that it is a subclass with Warning as the documentation states.
1379
Georg Brandlad29e632006-06-21 17:45:17 +00001380- The compiler module now correctly compiles the new try-except-finally
1381 statement (bug #1509132).
1382
Neal Norwitz60373cd2006-06-22 06:30:50 +00001383- The wsgiref package is now installed properly on Unix.
1384
Vinay Sajip28e57612006-07-01 10:45:20 +00001385- A bug was fixed in logging.config.fileConfig() which caused a crash on
1386 shutdown when fileConfig() was called multiple times.
1387
Gerhard Häring762fbd32006-07-02 17:48:30 +00001388- The sqlite3 module did cut off data from the SQLite database at the first
1389 null character before sending it to a custom converter. This has been fixed
1390 now.
1391

1393-----------------
1394
Tim Peters112aad32006-07-19 00:03:19 +00001395- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1396 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1397 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001398
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001399- Assigning None to pointer type fields in ctypes structures possible
1400 overwrote the wrong fields, this is fixed now.
1401
1402- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1403 on non-Windows platforms.
1404
1405- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1406 integer or long, without range checking.
1407
1408- Patch #1517790: It is now possible to use custom objects in the ctypes
1409 foreign function argtypes sequence as long as they provide a from_param
1410 method, no longer is it required that the object is a ctypes type.
1411
1412- The '_ctypes' extension module now works when Python is configured
1413 with the --without-threads option.
1414
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001415- Bug #1513646: os.access on Windows now correctly determines write

1430
Tim Peters32a83612006-07-10 21:08:24 +00001431- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001432 Previously, the slight difference could cause compilation errors of the
1433 'zlib' module on systems with more than one version of zlib.
1434
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001435- The MSI compileall step was fixed to also support a TARGETDIR
1436 with spaces in it.

1454 documentation for the warnings module.
1455
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001456- Patch #1509163: MS Toolkit Compiler no longer available.

1467-----------------
1468
Georg Brandla56b9152006-06-19 06:35:54 +00001469- Patch #1507676: Error messages returned by invalid abstract object operations
1470 (such as iterating over an integer) have been improved and now include the
1471 type of the offending object to help with debugging.
1472
Brett Cannonea3912b2006-06-13 21:46:41 +00001473- Bug #992017: A classic class that defined a __coerce__() method that returned
1474 its arguments swapped would infinitely recurse and segfault the interpreter.
1475
Neal Norwitz909eb122006-06-12 02:13:21 +00001476- Fix the socket tests so they can be run concurrently.
1477
Neal Norwitzb9845e72006-06-12 02:11:18 +00001478- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001479 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001480
Brett Cannon22565aa2006-06-09 22:31:23 +00001481- Bug #532646: object.__call__() will continue looking for the __call__
1482 attribute on objects until one without one is found. This leads to recursion
1483 when you take a class and set its __call__ attribute to an instance of the
1484 class. Originally fixed for classic classes, but this fix is for new-style.
1485 Removes the infinite_rec_3 crasher.
1486
Georg Brandl24250812006-06-09 18:45:48 +00001487- The string and unicode methods startswith() and endswith() now accept
1488 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1489
Brett Cannonde3b0522006-06-08 17:00:45 +00001490- Buffer objects, at the C level, never used the char buffer
1491 implementation even when the char buffer for the wrapped object was
1492 explicitly requested (originally returned the read or write buffer).
1493 Now a TypeError is raised if the char buffer is not present but is
1494 requested.
1495
Georg Brandlddbaa662006-06-04 21:56:52 +00001496- Patch #1346214: Statements like "if 0: suite" are now again optimized
1497 away like they were in Python 2.4.
1498
Georg Brandlb7c8f542006-05-27 12:30:25 +00001499- Builtin exceptions are now full-blown new-style classes instead of
1500 instances pretending to be classes, which speeds up exception handling
1501 by about 80% in comparison to 2.5a2.
1502
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001503- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1504 Unicode 4.1.
1505
Georg Brandlf4ef1162006-05-26 18:03:31 +00001506- Patch #921466: sys.path_importer_cache is now used to cache valid and
1507 invalid file paths for the built-in import machinery which leads to
1508 fewer open calls on startup.
1509
Tim Peters696cf432006-05-24 21:10:40 +00001510- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1511 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1512 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1513 the number of input digits (it was and remains linear-time for bases
1514 2, 4, 8, 16 and 32).
1515
Tim Petersb713ec22006-05-23 18:45:30 +00001516- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1517 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1518 an integer close to ``sys.maxint``. This was repaired by patch
1519 #1335972, which also gives a nice speedup.
1520
Richard Jonescebbefc2006-05-23 18:28:17 +00001521- Patch #1337051: reduced size of frame objects.
1522
1523- PyErr_NewException now accepts a tuple of base classes as its
1524 "base" parameter.
1525
Richard Jones7c88dcc2006-05-23 10:37:38 +00001526- Patch #876206: function call speedup by retaining allocated frame
1527 objects.
1528
Georg Brandl7b90e162006-05-18 07:01:27 +00001529- Bug #1462152: file() now checks more thoroughly for invalid mode
1530 strings and removes a possible "U" before passing the mode to the
1531 C library function.
1532
Neal Norwitz1004a532006-05-15 07:17:23 +00001533- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1534
Neal Norwitz373f0a72006-05-15 07:04:36 +00001535- Bug #1487966: Fix SystemError with conditional expression in assignment
1536
Martin v. Löwis879768d2006-05-11 13:28:43 +00001537- WindowsError now has two error code attributes: errno, which carries
1538 the error values from errno.h, and winerror, which carries the error
1539 values from winerror.h. Previous versions put the winerror.h values
1540 (from GetLastError()) into the errno attribute.
1541
Martin v. Löwis77736712006-05-04 05:51:03 +00001542- Patch #1475845: Raise IndentationError for unexpected indent.
1543
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001544- Patch #1479181: split open() and file() from being aliases for each other.
1545
Tim Peters44bd9862006-06-01 13:49:23 +00001546- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1547 methods were always silently ignored by dictionaries when comparing keys.
1548 They are now passed through (except when using the C API function
1549 ``PyDict_GetItem()``, whose semantics did not change).
1550
1551- Bug #1456209: In some obscure cases it was possible for a class with a
1552 custom ``__eq__()`` method to confuse dict internals when class instances
1553 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1554 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001556Extension Modules
1557-----------------
1558
Trent Mick960a3f82006-06-28 20:30:41 +00001559- Bug #1295808: expat symbols should be namespaced in pyexpat
1560
1561- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1562
Brett Cannon6ee7d012006-06-08 16:23:04 +00001563- Change binascii.hexlify to accept a read-only buffer instead of only a char
1564 buffer and actually follow its documentation.
1565
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001566- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1567
Nick Coghlanc649ec52006-05-29 12:43:05 +00001568- Patch #1478788 (modified version): The functional extension module has
1569 been renamed to _functools and a functools Python wrapper module added.
1570 This provides a home for additional function related utilities that are
1571 not specifically about functional programming. See PEP 309.
1572
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001573- Patch #1493701: performance enhancements for struct module.
1574
Georg Brandl378d5922006-05-17 14:26:50 +00001575- Patch #1490224: time.altzone is now set correctly on Cygwin.
1576
Georg Brandl8d3342b2006-05-16 07:38:27 +00001577- Patch #1435422: zlib's compress and decompress objects now have a
1578 copy() method.
1579
Andrew MacIntyre92913322006-06-13 15:04:24 +00001580- Patch #1454481: thread stack size is now tunable at runtime for thread
1581 enabled builds on Windows and systems with Posix threads support.
1582
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001583- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1584 (up to the system limit of 32K characters).
1585
1586- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1587 As a result, these functions now raise WindowsError instead of OSError.
1588
Tim Peters7a822da2006-05-25 21:50:17 +00001589- ``time.clock()`` on Win64 should use the high-performance Windows
1590 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1591 Windows platforms).
1592
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001593- Calling Tk_Init twice is refused if the first call failed as that
1594 may deadlock.
1595
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001596- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1597 accept it without potentially using an uninitialized pointer.
1598
1599- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1600 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1601 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001602
Gregory P. Smith372b5832006-06-05 18:48:21 +00001603- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001604 [pybsddb project SF patch number 1466734]
1605
Gregory P. Smith372b5832006-06-05 18:48:21 +00001606- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1607 parameter is supplied. [SF pybsddb bug #1477863]
1608
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001609- bsddb: the __len__ method of a DB object has been fixed to return correct
1610 results. It could previously incorrectly return 0 in some cases.
1611 Fixes SF bug 1493322 (pybsddb bug 1184012).
1612
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001613- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1614 aborts the db transaction safely when a modifier callback fails.
1615 Fixes SF python patch/bug #1408584.
1616
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001617- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001618 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001619 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1620 database calls that would previously deadlock. [SF python bug #775414]
1621
Vinay Sajip28e57612006-07-01 10:45:20 +00001622- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001623

1629
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001630- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1631 functions.
1632
Martin v. Löwis3798da02006-06-17 18:44:27 +00001633- Patch #812986: Update turtle output even if not tracing.
1634
Vinay Sajip28e57612006-07-01 10:45:20 +00001635- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001636 Tkinter.BaseWidget.
1637
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001638- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1639
Martin v. Löwis337487e2006-06-17 09:15:14 +00001640- Patch #763580: Add name and value arguments to Tkinter variable
1641 classes.
1642
Georg Brandl83cc0d02006-06-14 08:50:03 +00001643- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1644 mime.types file for determining MIME types.
1645
Georg Brandl2605ca82006-06-14 06:08:31 +00001646- Bug #1339007: Shelf objects now don't raise an exception in their
1647 __del__ method when initialization failed.
1648
Martin v. Löwisd8251432006-06-14 05:21:04 +00001649- Patch #1455898: The MBCS codec now supports the incremental mode for
1650 double-byte encodings.
1651
Tim Peters43898b42006-06-14 04:09:25 +00001652- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1653 guarantee that adjacent triples in the return list always describe
1654 non-adjacent blocks. Previously, a pair of matching blocks could end
1655 up being described by multiple adjacent triples that formed a partition
1656 of the matching pair.
1657
Greg Ward0e0c9f42006-06-11 16:24:11 +00001658- Bug #1498146: fix optparse to handle Unicode strings in option help,
1659 description, and epilog.
1660
Greg Wardd1c797e2006-06-11 14:42:41 +00001661- Bug #1366250: minor optparse documentation error.
1662
Greg Ward7f547402006-06-11 00:40:49 +00001663- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1664 clarify docs.
1665
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001666- The wsgiref package has been added to the standard library.
1667
Nick Coghlan676725d2006-06-08 13:54:49 +00001668- The functions update_wrapper() and wraps() have been added to the functools
1669 module. These make it easier to copy relevant metadata from the original
1670 function when writing wrapper functions.
1671
Tim Petersd6a9eef2006-06-05 01:48:21 +00001672- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1673 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001674
Martin v. Löwis3f767792006-06-04 19:36:28 +00001675- Patch #1359618: Speed up charmap encoder by using a trie structure
1676 for lookup.
1677
Tim Petersd609b1a2006-06-02 23:22:51 +00001678- The functions in the ``pprint`` module now sort dictionaries by key
1679 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1680 if and only if its display required more than one line, although that
1681 wasn't documented. The new behavior increases predictability; e.g.,
1682 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1683
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001684- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1685 (thanks for J. J. Lee).
1686
Georg Brandl2b330372006-05-28 20:23:12 +00001687- Patch #1496206: improve urllib2 handling of passwords with respect to
1688 default HTTP and HTTPS ports.
1689
George Yoshidaf3c65de2006-05-28 16:39:09 +00001690- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1691
Bob Ippolito7298f272006-05-23 18:43:47 +00001692- Patch #1281707: speed up gzip.readline.
1693
Georg Brandlb89316f2006-05-17 15:51:16 +00001694- Patch #1180296: Two new functions were added to the locale module:
1695 format_string() to get the effect of "format % items" but locale-aware,
1696 and currency() to format a monetary number with currency sign.
1697
Georg Brandle3a25832006-05-17 14:56:04 +00001698- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1699 and several features added, such as speed and geometry control.
1700
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001701- Patch #1488881: add support for external file objects in bz2 compressed
1702 tarfiles.
1703
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001704- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1705 stdout arguments, making it possible to redirect input and output
1706 for remote debugging.
1707
1708- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1709 a couple of issues, notably handling of long file names using the
1710 GNU LONGNAME extension.
1711
1712- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1713 new flag when ``name`` is already the name of an option flag.
1714
1715- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1716 package.
1717
1718- Patch #1472854: make the rlcompleter.Completer class usable on non-
1719 UNIX platforms.
1720
1721- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1722
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001723- Bug #1472827: correctly escape newlines and tabs in attribute values in
1724 the saxutils.XMLGenerator class.

1761
Thomas Heller1b046642006-04-18 18:51:06 +00001762- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1763 by converting these apis from macros into exported functions again:
1764
1765 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile

Martin v. Löwis45294a92006-04-18 06:24:08 +00001771- Under COUNT_ALLOCS, types are not necessarily immortal anymore.

Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001773- All uses of PyStructSequence_InitType have been changed to initialize
1774 the type objects only once, even if the interpreter is initialized
1775 multiple times.
1776
Neal Norwitz61546162006-04-14 05:20:28 +00001777- Bug #1454485, array.array('u') could crash the interpreter. This was
1778 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1779 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1780
1781- Py_UNICODE is unsigned. It was always documented as unsigned, but
1782 due to a bug had a signed value in previous versions.
1783
Tim Peters3a5e8b12006-04-11 01:44:07 +00001784- Patch #837242: ``id()`` of any Python object always gives a positive
1785 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1786 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001787 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001788 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001789
Tim Peters3a5e8b12006-04-11 01:44:07 +00001790 def __hash__(self):
1791 return id(self) # WRONG
1792
1793 because a hash result must be a (short) Python int but it was always
1794 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001795 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001796 was always usable as a hash value before this patch. That's no longer
1797 necessarily so.
1798
1799- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001800 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001801 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001802 #1454844)
1803
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001804- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1805 involving generators that have paused outside of any ``try`` or ``with``
1806 blocks. (In 2.5a1, a paused generator that was part of a reference
1807 cycle could not be garbage collected, regardless of whether it was
1808 paused in a ``try`` or ``with`` block.)

1815
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001816- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1817 fails with an error condition.
1818
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001819- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1820
1821- Bug #1117761: bsddb.*open() no longer raises an exception when using
1822 the cachesize parameter.
1823
1824- Bug #1149413: bsddb.*open() no longer raises an exception when using
1825 a temporary db (file=None) with the 'n' flag to truncate on open.
1826
1827- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1828 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001829
Armin Rigoa9017c32006-04-19 11:50:27 +00001830- Patch #1062014: AF_UNIX sockets under Linux have a special
1831 abstract namespace that is now fully supported.
1832

1834-------
1835
Peter Astrand7d1d4362006-07-14 14:04:45 +00001836- Bug #1223937: subprocess.CalledProcessError reports the exit status
1837 of the process using the returncode attribute, instead of
1838 abusing errno.
1839
Tim Peters711bf302006-04-25 03:31:36 +00001840- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1841 a doctest to be skipped (the code is not run, and the expected output
1842 or exception is ignored).
1843
Nick Coghlanda2268f2006-04-24 04:37:15 +00001844- Fixed contextlib.nested to cope with exceptions being raised and
1845 caught inside exit handlers.
1846
Greg Wardab05edc2006-04-23 03:47:58 +00001847- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1848 hex, octal, or binary; add ``append_const`` action; keep going if
1849 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1850 added ``epilog`` for better help generation).
1851
Tim Peters21fbd572006-04-21 21:18:10 +00001852- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1853 called from a thread spawned as a side effect of importing a module.
1854
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001855- The pydoc module now supports documenting packages contained in
1856 .zip or .egg files.
1857
1858- The pkgutil module now has several new utility functions, such
1859 as ``walk_packages()`` to support working with packages that are either
1860 in the filesystem or zip files.
1861
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001862- The mailbox module can now modify and delete messages from
1863 mailboxes, in addition to simply reading them. Thanks to Gregory
1864 K. Johnson for writing the code, and to the 2005 Google Summer of
1865 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001866
Tim Petersc7605f22006-04-17 21:12:33 +00001867- The ``__del__`` method of class ``local`` in module ``_threading_local``
1868 returned before accomplishing any of its intended cleanup.

1875
Anthony Baxtere29002c2006-04-12 12:07:31 +00001876- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1877 Windows. Bug #1469163.
1878
Phillip J. Eby47032112006-04-11 01:07:43 +00001879- The warnings, linecache, inspect, traceback, site, and doctest modules
1880 were updated to work correctly with modules imported from zipfiles or
1881 via other PEP 302 __loader__ objects.
1882
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001883- Patch #1467770: Reduce usage of subprocess._active to processes which
1884 the application hasn't waited on.

1889
Skip Montanaro262fb922006-04-21 02:31:07 +00001890- The pstats.Stats class accepts an optional stream keyword argument to
1891 direct output to an alternate file-like object.
1892
Anthony Baxter51bcb682006-04-05 14:51:42 +00001893Build
1894-----
1895
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001896- The Makefile now has a reindent target, which runs reindent.py on
1897 the library.
1898
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001899- Patch #1470875: Building Python with MS Free Compiler
1900
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001901- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001902
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001903- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1904 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001905 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001906 CXX from --with-cxx-main, see description in README.
1907
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001908- Patch #1429775: Link extension modules with the shared libpython.
1909
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001910- Fixed a libffi build problem on MIPS systems.
1911
Tim Peters8931ff12006-05-13 23:28:20 +00001912- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1913 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1914 and "%zu" for unsigned integers of type ``size_t``.
1915
Anthony Baxter51bcb682006-04-05 14:51:42 +00001916Tests
1917-----
1918
Nick Coghlanda2268f2006-04-24 04:37:15 +00001919- test_contextlib now checks contextlib.nested can cope with exceptions
1920 being raised and caught inside exit handlers.
1921
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001922- test_cmd_line now checks operation of the -m and -c command switches
1923
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001924- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1925 it separately and by hand. It also wasn't cleaning up its changes to
1926 the current Decimal context.
1927
Thomas Woutersabd08882006-04-26 15:53:30 +00001928- regrtest.py now has a -M option to run tests that test the new limits of
1929 containers, on 64-bit architectures. Running these tests is only sensible
1930 on 64-bit machines with more than two gigabytes of memory. The argument
1931 passed is the maximum amount of memory for the tests to use.

1940-------------
1941
Tim Petersb06d28c2006-05-12 01:57:59 +00001942- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1943
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001944- PEP 343: Added Context Types section to the library reference
1945 and attempted to bring other PEP 343 related documentation into
1946 line with the implementation and/or python-dev discussions.
1947
Tim Peters8dc73d22006-04-24 02:03:16 +00001948- Bug #1337990: clarified that ``doctest`` does not support examples
1949 requiring both expected output and an exception.

Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001956
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001957Core and builtins
1958-----------------
1959
Nick Coghlan43832302006-04-23 17:04:07 +00001960- PEP 338: -m command line switch now delegates to runpy.run_module
1961 allowing it to support modules in packages and zipfiles
1962
Martin v. Löwisc661b882006-04-20 04:54:23 +00001963- On Windows, .DLL is not an accepted file name extension for
1964 extension modules anymore; extensions are only found if they
1965 end in .PYD.
1966
Martin v. Löwisea62d252006-04-03 10:56:49 +00001967- Bug #1421664: sys.stderr.encoding is now set to the same value as
1968 sys.stdout.encoding.
1969
Neal Norwitz92e212f2006-04-03 04:48:37 +00001970- __import__ accepts keyword arguments.
1971
Georg Brandlccadf842006-03-31 18:54:53 +00001972- Patch #1460496: round() now accepts keyword arguments.
1973
Anthony Baxter262c00a2006-03-30 10:53:17 +00001974- Fixed bug #1459029 - unicode reprs were double-escaped.
1975
Hye-Shik Changd478f342006-03-23 12:32:36 +00001976- Patch #1396919: The system scope threads are reenabled on FreeBSD
1977 5.4 and later versions.
1978
Neal Norwitze98ccf62006-03-23 05:39:47 +00001979- Bug #1115379: Compiling a Unicode string with an encoding declaration
1980 now gives a SyntaxError.
1981
Georg Brandlabd1ff82006-03-18 07:59:59 +00001982- Previously, Python code had no easy way to access the contents of a
1983 cell object. Now, a ``cell_contents`` attribute has been added
1984 (closes patch #1170323).
1985
Tim Peterscf79aac2006-03-16 01:14:46 +00001986- Patch #1123430: Python's small-object allocator now returns an arena to
1987 the system ``free()`` when all memory within an arena becomes unused
1988 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1989 freed. Some applications will see a drop in virtual memory size now,
1990 especially long-running applications that, from time to time, temporarily
1991 use a large number of small objects. Note that when Python returns an
1992 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001993 platform C library will in turn return that memory to the operating system.
1994 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001995 appears to be effective at least on Microsoft C and gcc-based systems.
1996 Thanks to Evan Jones for hard work and patience.
1997
Georg Brandl533ff6f2006-03-08 18:09:27 +00001998- Patch #1434038: property() now uses the getter's docstring if there is
1999 no "doc" argument given. This makes it possible to legitimately use
2000 property() as a decorator to produce a read-only property.
2001
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002002- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2003 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2004 of requiring an int or long in slicing and a few other contexts, enabling
2005 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2006
Neal Norwitz995acdf2006-03-07 05:01:00 +00002007- Fixed various bugs reported by Coverity's Prevent tool.
2008
Brett Cannonbf364092006-03-01 04:25:17 +00002009- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2010 new exception base class, BaseException, which has a new message attribute.
2011 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2012 Raising a string exception now raises a DeprecationWarning.
2013
Thomas Woutersfb609f42006-02-28 16:37:25 +00002014- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2015 explicitly relative, using 'from .module import name' to mean 'from the same
2016 package as this module is in. Imports without dots still default to the
2017 old relative-then-absolute, unless 'from __future__ import
2018 absolute_import' is used.
2019
Brett Cannona7446e32006-02-27 23:39:10 +00002020- Properly check if 'warnings' raises an exception (usually when a filter set
2021 to "error" is triggered) when raising a warning for raising string
2022 exceptions.
2023
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002024- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002025 The name was removed from Include/code.h.
2026
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002027- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002028
Guido van Rossum1968ad32006-02-25 22:38:04 +00002029- Patch 1433928:
2030 - The copy module now "copies" function objects (as atomic objects).
2031 - dict.__getitem__ now looks for a __missing__ hook before raising
2032 KeyError.
2033
Tim Peters84ef21c2006-02-28 20:39:06 +00002034- PEP 343: with statement implemented. Needs ``from __future__ import
2035 with_statement``. Use of 'with' as a variable will generate a warning.
2036 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002037 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002038 The following objects have __context__ methods:
2039 - The built-in file type.
2040 - The thread.LockType type.
2041 - The following types defined by the threading module:
2042 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2043 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002044
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002045- Fix the encodings package codec search function to only search
2046 inside its own package. Fixes problem reported in patch #1433198.
2047
2048 Note: Codec packages should implement and register their own
2049 codec search function. PEP 100 has the details.
2050
Tim Peters9ea89d22006-06-04 03:26:02 +00002051- PEP 353: Using ``Py_ssize_t`` as the index type.
2052
2053- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2054 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2055 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2056 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2057 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002058
Neal Norwitzfc76d632006-01-10 06:03:13 +00002059- Patch #1400181, fix unicode string formatting to not use the locale.
2060 This is how string objects work. u'%f' could use , instead of .
2061 for the decimal point. Now both strings and unicode always use periods.
2062
Neal Norwitz671b9e32006-01-09 07:07:12 +00002063- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2064 configure would break checking curses.h.
2065
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002066- Bug #959576: The pwd module is now builtin. This allows Python to be
2067 built on UNIX platforms without $HOME set.
2068
Neal Norwitzc10978f2005-12-19 06:07:16 +00002069- Bug #1072182, fix some potential problems if characters are signed.
2070
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002071- Bug #889500, fix line number on SyntaxWarning for global declarations.
2072
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002073- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2074
Neal Norwitze7214a12005-12-18 05:03:17 +00002075- Support for converting hex strings to floats no longer works.
2076 This was not portable. float('0x3') now raises a ValueError.
2077
Barry Warsaw2a38a862005-12-18 01:27:35 +00002078- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002079 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002080 is now displayed in interactive prompt banner.
2081
Georg Brandlfa166682005-12-17 21:45:17 +00002082- Implementation of PEP 341 - Unification of try/except and try/finally.
2083 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002084 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002085
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002086- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2087 now encodes backslash correctly.
2088
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002089- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2090
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002091- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002092 and long longs.
2093
Neal Norwitz67715f02005-11-09 06:59:35 +00002094- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002095 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002096 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002097
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002098- Replaced most Unicode charmap codecs with new ones using the
2099 new Unicode translate string feature in the builtin charmap
2100 codec; the codecs were created from the mapping tables available
2101 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2102 encodings now include a mapping for the Apple logo)
2103
Tim Peterse3547fd2005-12-16 23:13:57 +00002104- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002105
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002106- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002107
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002108- A new AST parser implementation was completed. The abstract
2109 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002110 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002111
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002112- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002113 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2114
Neal Norwitz708e51a2005-10-03 04:48:15 +00002115- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2116
Neal Norwitz11bd1192005-10-03 00:54:56 +00002117- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2118 Provide a warning when a directory is passed on the command line.
2119
Neal Norwitz40d37812005-10-02 01:48:49 +00002120- Fix segfault with invalid coding.
2121
2122- SF bug #772896: unknown encoding results in MemoryError.
2123
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002124- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002125 supported a __len__() method which evaluated to False when the iterator
2126 was empty.
2127
Guido van Rossum630db602005-09-20 18:49:54 +00002128- On 64-bit platforms, when __len__() returns a value that cannot be
2129 represented as a C int, raise OverflowError.
2130
Skip Montanarof8948ca2005-09-19 03:54:46 +00002131- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002132 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002133
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002134- SF bug #893549: parsing keyword arguments was broken with a few format
2135 codes.
2136
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002137- Changes donated by Elemental Security to make it work on AIX 5.3
2138 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2139 bug #105470: test_pwd fails on 64bit system (Opteron).
2140
Guido van Rossum539c6622005-09-14 17:49:54 +00002141- Changes donated by Elemental Security to make it work on HP-UX 11 on
2142 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2143
Georg Brandl4550b8d2005-08-26 06:43:52 +00002144- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002145 (fixes bug #1119418).
2146
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002147- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2148
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002149- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2150 exceptions that cause a function to exit.
2151
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002152- The implementation of set() and frozenset() was revised to use its
2153 own internal data structure. Memory consumption is reduced by 1/3
2154 and there are modest speed-ups as well. The API is unchanged.
2155
Tim Petersde7990b2005-07-17 23:45:23 +00002156- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2157
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002158- SF bug #1229429: PyObject_CallMethod failed to decrement some
2159 reference counts in some error exit cases.
2160
Tim Petersecc6e6a2005-07-10 22:30:55 +00002161- SF bug #1185883: Python's small-object memory allocator took over
2162 a block managed by the platform C library whenever a realloc specified
2163 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002164 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002165 portable way to copy data from the C-managed block into Python's
2166 small-object space without risking a memory fault. Python's small-object
2167 realloc now leaves such blocks under the control of the platform C
2168 realloc.
2169
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002170- SF bug #1232517: An overflow error was not detected properly when
2171 attempting to convert a large float to an int in os.utime().
2172
Raymond Hettinger3296e692005-06-29 23:29:56 +00002173- SF bug #1224347: hex longs now print with lowercase letters just
2174 like their int counterparts.
2175
Michael W. Hudson188d4362005-06-20 16:52:57 +00002176- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2177 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2178 interpreter states; back out that fix and do a better job (see
2179 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2180 for a longer write-up of the problem).
2181
Michael W. Hudsondf888462005-06-03 14:41:55 +00002182- SF patch #1180995: marshal now uses a binary format by default when
2183 serializing floats.
2184
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002185- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2186 the routines that promise to produce IEEE 754 binary representations
2187 of floats now simply copy bytes around.
2188
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002189- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2190 278.
2191
Brett Cannonc3647ac2005-04-26 03:45:26 +00002192- patch #1109424: int, long, float, complex, and unicode now check for the
2193 proper magic slot for type conversions when subclassed. Previously the
2194 magic slot was ignored during conversion. Semantics now match the way
2195 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002196 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002197 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002198 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002199
Barry Warsawc8d907c2005-04-19 23:43:40 +00002200- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2201 NULL, now raise an AttributeError when attempting to set or delete the
2202 attribute. Previously a TypeError was raised, but this was inconsistent
2203 with the equivalent pure-Python implementation.
2204
Michael W. Hudson774479c2005-04-18 08:46:17 +00002205- It is now safe to call PyGILState_Release() before
2206 PyEval_InitThreads() (note that if there is reason to believe there
2207 are multiple threads around you still must call PyEval_InitThreads()
2208 before using the Python API; this fix is for extension modules that
2209 have no way of knowing if Python is multi-threaded yet).
2210
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002211- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2212 disabled caused a crash.
2213
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002214- Bug #1165306: instancemethod_new allowed the creation of a method
2215 with im_class == im_self == NULL, which caused a crash when called.
2216
Tim Petersecc6e6a2005-07-10 22:30:55 +00002217- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002218 fixes the crash seen in bug #1165761
2219
Raymond Hettinger96229b12005-03-11 06:49:40 +00002220- Added two new builtins, any() and all().
2221
Brett Cannon409d8f22005-03-05 06:47:57 +00002222- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002223 (e.g., ``class C(): pass`` is no longer a syntax error).
2224 Patch #1176012 added support to the 'parser' module and 'compiler' package
2225 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002226
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002227- Patch #1115086: Support PY_LONGLONG in structmember.
2228
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002229- Bug #1155938: new style classes did not check that __init__() was
2230 returning None.
2231
Tim Petersecc6e6a2005-07-10 22:30:55 +00002232- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002233 ('\') with a specific error message.
2234
Martin v. Löwisff232d72005-03-03 09:24:38 +00002235- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2236
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002237- Bug #1124295: the __name__ attribute of file objects was
2238 inadvertently made inaccessible in restricted mode.
2239
Tim Petersecc6e6a2005-07-10 22:30:55 +00002240- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002241 an ferror() call.
2242
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002243- min() and max() now support key= arguments with the same meaning as in
2244 list.sort().
2245
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002246- The peephole optimizer now performs simple constant folding in expressions:
2247 (2+3) --> (5).
2248
Raymond Hettingera422c342005-01-11 03:03:27 +00002249- set and frozenset objects can now be marshalled. SF #1098985.
2250
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002251- Bug #1077106: Poor argument checking could cause memory corruption
2252 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002253
Jeremy Hyltonab630502005-02-04 18:44:06 +00002254- The parser did not complain about future statements in illegal
2255 positions. It once again reports a syntax error if a future
2256 statement occurs after anything other than a doc string.
2257
Neil Schemenauercf52c072005-08-12 17:34:58 +00002258- Change the %s format specifier for str objects so that it returns a
2259 unicode instance if the argument is not an instance of basestring and
2260 calling __str__ on the argument returns a unicode instance.
2261
Tim Petersf4e69282006-02-27 17:15:31 +00002262- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2263 current thread state when the auto-GIL-state machinery knows about
2264 it (since the thread state is being deleted, continuing to remember it
2265 can't help, but can hurt if another thread happens to get created with
2266 the same thread id).
2267
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002268Extension Modules
2269-----------------
2270
Georg Brandl43f08a82006-03-31 18:01:16 +00002271- Patch #1380952: fix SSL objects timing out on consecutive read()s

2274
Anthony Baxterfa869072006-03-20 05:21:58 +00002275- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
2276 In addition, the existing ulaw code was updated.
2277
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002278- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00002279 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002280
Neal Norwitz10be10c2006-03-16 06:50:13 +00002281- Everything under lib-old was removed. This includes the following modules:
2282 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00002283 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00002284 util, whatsound, whrandom, zmod
2285
2286- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2287
2288- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002289 is deprecated. The undocumented re.engine variable no longer exists.
2290
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002291- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2292 SS2 (single-shift 2) escape sequences correctly.
2293
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002294- The unicodedata module was updated to the 4.1 version of the Unicode
2295 database. The 3.2 version is still available as unicodedata.db_3_2_0
2296 for applications that require this specific version (such as IDNA).
2297
Neal Norwitzb62c4332006-03-04 18:35:47 +00002298- The timing module is no longer built by default. It was deprecated
2299 in PEP 4 in Python 2.0 or earlier.
2300
Guido van Rossum1968ad32006-02-25 22:38:04 +00002301- Patch 1433928: Added a new type, defaultdict, to the collections module.
2302 This uses the new __missing__ hook behavior added to dict (see above).
2303
Georg Brandldbd83392006-02-20 09:42:33 +00002304- Bug #854823: socketmodule now builds on Sun platforms even when
2305 INET_ADDRSTRLEN is not defined.
2306
Georg Brandlf4f44152006-02-18 22:29:33 +00002307- Patch #1393157: os.startfile() now has an optional argument to specify
2308 a "command verb" to invoke on the file.
2309
Neal Norwitz082b2df2006-02-07 07:04:46 +00002310- Bug #876637, prevent stack corruption when socket descriptor
2311 is larger than FD_SETSIZE.
2312
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00002313- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
2314 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
2315 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
2316
Martin v. Löwis57a34e82006-02-04 19:12:37 +00002317- Patch #1422385: The nis module now supports access to domains other
2318 than the system default domain.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002458- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2459 been renamed to have only a single underscore prefix. This was done to
2460 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002461
Nick Coghlan43832302006-04-23 17:04:07 +00002462- PEP 338: new module runpy defines a run_module function to support
2463 executing modules which provide access to source code or a code object
2464 via the PEP 302 import mechanisms.
2465
Anthony Baxter93f5b932006-04-03 08:05:07 +00002466- The email module's parsedate_tz function now sets the daylight savings

2474 in attribute values.
2475
Anthony Baxterc51ee692006-04-01 00:57:31 +00002476- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002477 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002478 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002479 module will not be built.
2480
Tim Petersc17976e2006-04-01 00:26:53 +00002481- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2482 aren't officially supported here, and trying to use them will probably
2483 raise an exception some day. But dicts have been allowed, and "mostly
2484 worked", so support for them won't go away without warning.
2485
Georg Brandl338ef7d2006-03-31 18:42:16 +00002486- Bug #1445068: getpass.getpass() can now be given an explicit stream
2487 argument to specify where to write the prompt.
2488

2504
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002505- email 4.0 package now integrated. This is largely the same as the email 3.0
2506 package that was included in Python 2.3, except that PEP 8 module names are
2507 now used (e.g. mail.message instead of email.Message). The MIME classes
2508 have been moved to a subpackage (e.g. email.mime.text instead of
2509 email.MIMEText). The old names are still supported for now. Several
2510 deprecated Message methods have been removed and lots of bugs have been
2511 fixed. More details can be found in the email package documentation.
2512
Walter Dörwald40108c92006-03-27 08:15:44 +00002513- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2514 (a subclass of tuple) that provides incremental decoders and encoders
2515 (a way to use stateful codecs without the stream API). Python functions
2516 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2517 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2518 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002519
Walter Dörwald067db482006-03-15 22:17:27 +00002520- Patch #1359365: Calling next() on a closed StringIO.String object raises
2521 a ValueError instead of a StopIteration now (like file and cString.String do).
2522 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2523 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002524
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002525- A regrtest option -w was added to re-run failed tests in verbose mode.

Georg Brandl4edd9892006-01-13 16:59:46 +00002585- Bug #1403410: The warnings module now doesn't get confused
2586 when it can't find out the module name it generates a warning for.
Georg Brandlb709c2c2006-01-20 09:07:35 +00002587

2591
Neal Norwitz338e7862005-12-23 21:27:46 +00002592- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
2593 LoadError as documented, instead of IOError. For compatibility,
2594 LoadError subclasses IOError.
2595
Brett Cannon3cbd0382005-12-16 22:49:23 +00002596- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00002597 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2598 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2599 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2600 Ronald L. Rivest offered this advice for Python:
2601
2602 "The consensus of researchers in this area (at least as
2603 expressed at the NIST Hash Function Workshop 10/31/05),
2604 is that SHA-256 is a good choice for the time being, but
2605 that research should continue, and other alternatives may
2606 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002607
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002608- Added a subset of Fredrik Lundh's ElementTree package. Available

2661 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002662 correct line numbers for decoding errors in source code.

2685 to W3C name (404 -> 'Not Found'). RFE #1216944.
2686
Georg Brandl9e43acf2005-07-04 17:16:07 +00002687- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2688 as this can cause problems with apps closing all file descriptors.

2701 Bug #1224621.
2702
Raymond Hettinger68c04532005-06-10 11:05:19 +00002703- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002704 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002705 the generate_tokens() function now accepts a callable argument that
2706 terminates by raising StopIteration.
2707
Georg Brandl9166e1a2005-06-04 09:20:03 +00002708- Bug #1196315: fix weakref.WeakValueDictionary constructor.

2712
Skip Montanaro174dd222005-05-14 20:54:16 +00002713- Patch #1120353: The xmlrpclib module provides better, more transparent,

2716 class at all.
2717
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002718- distutils.commands.upload was added to support uploading distribution

2722 them to PyPI.
2723
Raymond Hettinger267b8682005-03-27 10:47:39 +00002724- decimal operator and comparison methods now return NotImplemented
2725 instead of raising a TypeError when interacting with other types. This
2726 allows other classes to implement __radd__ style methods and have them
2727 work as expected.
2728
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002729- Bug #1163325: Decimal infinities failed to hash. Attempting to
2730 hash a NaN raised an InvalidOperation instead of a TypeError.
2731
Tim Petersecc6e6a2005-07-10 22:30:55 +00002732- Patch #918101: Add tarfile open mode r|* for auto-detection of the

2766
Guido van Rossumd0641422005-02-03 15:01:24 +00002767- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2768 disables recursive traversal through instance attributes, which can
2769 be exploited in various ways.
2770
Tim Peterse3547fd2005-12-16 23:13:57 +00002771- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002772 flags on the HTTP listening socket.
2773
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002774- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2775 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2776

Thomas Hellerd6c6e222005-01-20 19:20:16 +00002782- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2783
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002784- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2785
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002786- Enhancements to the csv module:
2787
2788 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002789 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002790 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002791 + Dialect parameter parsing has been re-implemented to improve error
2792 reporting.
2793 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2794 dictates.
2795 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002796 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002797 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002798 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2799 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002800 + reader now allows \r characters to be quoted (previously it only allowed
2801 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002802 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002803 + Dialect classes passed to the module are no longer instantiated by
2804 the module before being parsed (the former validation scheme required
2805 this, but the mechanism was unreliable).
2806 + The dialect registry now contains instances of the internal
2807 C-coded dialect type, rather than references to python objects.
2808 + the internal c-coded dialect type is now immutable.
2809 + register_dialect now accepts the same keyword dialect specifications
2810 as the reader and writer, allowing the user to register dialects
2811 without first creating a dialect class.
2812 + a configurable limit to the size of parsed fields has been added -
2813 previously, an unmatched quote character could result in the entire
2814 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002815 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002816 the parser field size limit (returning the former limit). The initial
2817 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002818 + A line_num attribute has been added to the reader object, which tracks
2819 the number of lines read from the source iterator. This is not
2820 the same as the number of records returned, as records can span
2821 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002822 + reader and writer objects were not being registered with the cyclic-GC.
2823 This has been fixed.
2824
Brett Cannone6539c42005-01-08 02:43:53 +00002825- _DummyThread objects in the threading module now delete self.__block that is
2826 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2827 lock primitives tend to be limited in number and thus should not be wasted on
2828 a _DummyThread object. Fixes bug #1089632.
2829
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002830- The imghdr module now detects Exif files.
2831
Raymond Hettinger6065d322004-12-20 23:51:53 +00002832- StringIO.truncate() now correctly adjusts the size attribute.
2833 (Bug #951915).
2834
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002835- locale.py now uses an updated locale alias table (built using
2836 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2837 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002838 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002839
Raymond Hettinger3557f422004-12-07 12:02:02 +00002840- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2841
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002842- the pickle module no longer accepts the deprecated None option in the
2843 args tuple returned by __reduce__().
2844
Brett Cannon84667c02004-12-07 03:25:18 +00002845- optparse now optionally imports gettext. This allows its use in setup.py.
2846
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002847- the pickle module no longer uses the deprecated bin parameter.
2848

2854
Raymond Hettinger664347b2004-12-04 21:21:53 +00002855- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2856 extended or overridden by subclasses. Formerly, the subclassed method would
2857 be ignored by the rest of the module. (Bug #1078905).
2858
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002859- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002860 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002861
Walter Dörwald36733692004-12-22 12:50:50 +00002862- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2863 once when a size argument is given. This prevents a buffer overflow in the
2864 tokenizer with very long source lines.
2865
Barry Warsaw538561e2006-01-01 21:48:54 +00002866- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2867 immediately after creating the object, without any intervening
2868 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002869
Skip Montanaro05885812005-01-16 20:48:27 +00002870- The reconvert.quote function can now emit triple-quoted strings. The
2871 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002872
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002873- ``UserString.MutableString`` now supports negative indices in
2874 ``__setitem__`` and ``__delitem__``
2875
Greg Ward40407942005-03-05 02:53:17 +00002876- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2877 correctly.
2878
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002879- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2880 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2881 character even if the user has passed a size parameter to get a proper
2882 line ending. Remove the special handling of a "\r\n" that has been split
2883 between two lines.
2884
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002885- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2886 about illegal code points. The codec now supports PEP 293 style error
2887 handlers.
2888
Walter Dörwald78a78b02005-09-01 12:04:29 +00002889- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002890 from the input stream, so that the output is a byte string in the correct
2891 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002892
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002893- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2894 considering it exactly like a '*'.
2895
Walter Dörwald007f8df2005-10-09 19:42:27 +00002896- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2897 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002898
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002899- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2900
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002901- Patch #1413711: Certain patterns of differences were making difflib
2902 touch the recursion limit.
2903
Walter Dörwald58917a62006-03-31 15:26:22 +00002904- Bug #947906: An object oriented interface has been added to the calendar
2905 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002906 called as a script (e.g. via ``python -mcalendar``). Localized month and
2907 weekday names can be ouput (even if an exotic encoding is used) using
2908 special classes that use unicode.

2911-----
2912
Neal Norwitz602d3392006-03-31 08:21:40 +00002913- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2914 by using -mieee gcc option.
2915

2917
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002918- Build support for Win64-AMD64 was added.
2919
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002920- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2921
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002922- Patch #881820: look for openpty and forkpty also in libbsd.
2923
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002924- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2925 The zlib module is now builtin on Windows.
2926
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002927- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2928
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002929- Bug #1189330: configure did not correctly determine the necessary
2930 value of LINKCC if python was built with GCC 4.0.
2931
Trent Mick8321b422005-07-26 02:29:21 +00002932- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2933 vulnerability in zlib 1.2.1 and 1.2.2.
2934
Brett Cannon08cd5982005-04-24 22:26:38 +00002935- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2936 flags that change binary compatibility. Changes were also made to
2937 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002938 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002939
Bob Ippolitoed233462005-03-29 13:47:59 +00002940- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2941 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2942 no longer exists). This configure patch makes things right.
2943
Martin v. Löwise2713be2005-03-08 15:03:08 +00002944- Bug #1158607: Build with --disable-unicode again.
2945
Brett Cannon46d96232005-02-16 00:07:19 +00002946- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2947 defined. Discovered as a result of not being able to build on OS X.
2948
Brett Cannon516592f2004-12-07 00:42:59 +00002949- setup.py now uses the directories specified in LDFLAGS using the -L option
2950 and in CPPFLAGS using the -I option for adding library and include
2951 directories, respectively, for compiling extension modules against. This has
2952 led to the core being compiled using the values in CPPFLAGS. It also removes
2953 the need for the special-casing of both DarwinPorts and Fink for darwin since
2954 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2955 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2956 Fink, ``-I/opt/local/include`` for DarwinPorts).
2957
Brett Cannon43802422005-02-10 20:48:03 +00002958- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2959 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2960 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2961 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002963C API
2964-----
2965
Tim Petersc9d78aa2006-03-26 23:27:58 +00002966- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2967 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2968 is obtained via the ``PyObject_`` family, it must be released via the
2969 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2970 always been officially true, but when Python's small-object allocator was
2971 introduced, an attempt was made to cater to a few extension modules
2972 discovered at the time that obtained memory via ``PyObject_New`` but
2973 released it via ``PyMem_DEL``. It's years later, and if such code still
2974 exists it will fail now (probably with segfaults, but calling wrong
2975 low-level memory management functions can yield many symptoms).
2976
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002977- Added a C API for set and frozenset objects.
2978
Raymond Hettinger66517482004-12-03 11:45:13 +00002979- Removed PyRange_New().
2980
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002981- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2982 mapping argument now. This string is used as a mapping table. Byte values
2983 greater than the length of the string and 0xFFFE are treated as undefined
2984 mappings.

2989
Martin v. Löwis4d394df2005-01-23 09:19:22 +00002990- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002991
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002992- Patch #1276356: New resource "urlfetch" is implemented. This enables
2993 even impatient people to run tests that require remote files.
