Guido van Rossumc69ac252006-08-10 18:09:25 +0000902What's New in Python 2.5 release candidate 1?
903=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000904
Anthony Baxterb4096662006-08-16 03:42:26 +0000905*Release date: 17-AUG-2006*
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000906
907Core and builtins
908-----------------
909
Neal Norwitz24b6f202006-09-05 04:43:56 +0000910- Fix infinite recursion when subclassing long and overriding __hash__.
911
912- Fix concatenation (+=) of long strings.
913
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000914- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000915 compared equal or unequal to a string and a UnicodeDecodeError
916 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000917
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000918 Instead, the equal (==) and unequal (!=) comparison operators will
919 now issue a UnicodeWarning and interpret the two objects as
920 unequal. The UnicodeWarning can be filtered as desired using
921 the warning framework, e.g. silenced completely, turned into an
922 exception, logged, etc.
923
924 Note that compare operators other than equal and unequal will still
925 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000926
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000927- Fix segfault when doing string formatting on subclasses of long.
928
929- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
930 with new-style classes.
931
932- Fix bug related to __len__ functions returning negative values with
933 classic classes.
934
935- Patch #1538606, Fix __index__() clipping. There were some problems
936 discovered with the API and how integers that didn't fit into Py_ssize_t
937 were handled. This patch attempts to provide enough alternatives
938 to effectively use __index__.
939
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000940- Bug #1536021: __hash__ may now return long int; the final hash
941 value is obtained by invoking hash on the long int.
942
Thomas Hellerab1049c2006-08-08 17:37:00 +0000943- Bug #1536786: buffer comparison could emit a RuntimeWarning.
944
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000945- Bug #1535165: fixed a segfault in input() and raw_input() when
946 sys.stdin is closed.
947
Thomas Heller74d36f02006-08-04 18:17:40 +0000948- On Windows, the PyErr_Warn function is now exported from
949 the Python dll again.
950
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000951- Bug #1191458: tracing over for loops now produces a line event
952 on each iteration. Fixing this problem required changing the .pyc
953 magic number. This means that .pyc files generated before 2.5c1
954 will be regenerated.
955
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000956- Bug #1333982: string/number constants were inappropriately stored
957 in the byte code and co_consts even if they were not used, ie
958 immediately popped off the stack.
959
Georg Brandle9462c72006-08-04 18:03:37 +0000960- Fixed a reference-counting problem in property().
961
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000962
963Library
964-------
965
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000966- Fix a bug in the ``compiler`` package that caused invalid code to be
967 generated for generator expressions.
968
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000969- The distutils version has been changed to 2.5.0. The change to
970 keep it programmatically in sync with the Python version running
971 the code (introduced in 2.5b3) has been reverted. It will continue
972 to be maintained manually as static string literal.
973
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000974- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000975 and this cannot be converted to the required C type, an exception is
976 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000977 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000978
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000979- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000980 an exception.
981
Tim Peterscbdd3502006-09-05 01:47:53 +0000982- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000983 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000984 workarounds for clocks with low resolution, to stop the code yielding
985 duplicate UUIDs.
986
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000987- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
988 before raising SystemExit, allowing IDLE to honor quit() and exit().
989
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000990- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
991
Georg Brandl7a1af772006-08-14 21:55:28 +0000992- Patch #1536071: trace.py should now find the full module name of a
993 file correctly even on Windows.
994
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000995- logging's atexit hook now runs even if the rest of the module has
996 already been cleaned up.
997
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000998- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000999
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001000- Bug #1531405, format_exception no longer raises an exception if
1001 str(exception) raised an exception.
1002
Neil Schemenauer06ded092006-08-04 16:20:30 +00001003- Fix a bug in the ``compiler`` package that caused invalid code to be
1004 generated for nested functions.
1005
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001006

1013
Georg Brandl3335a7a2006-08-14 21:42:55 +00001014- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
1015 raises the correct exceptions.
1016
Thomas Heller1ce433e2006-08-14 16:20:04 +00001017- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1018 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1019
Thomas Heller86720042006-08-14 11:17:48 +00001020- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1021 uses the _as_parameter_ attribute when objects are passed to foreign
1022 function calls. The ctypes version number was changed to 1.0.1.
1023
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001024- Bug #1530559, struct.pack raises TypeError where it used to convert.
1025 Passing float arguments to struct.pack when integers are expected
1026 now triggers a DeprecationWarning.
1027
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001028

Martin v. Löwisa09fd6e2006-08-16 12:55:10 +00001052- Bug #1535502, build _hashlib on Windows, and use masm assembler
1053 code in OpenSSL.
1054
Thomas Hellerdb7b4432006-08-04 19:49:31 +00001055- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

Thomas Heller17984892006-08-04 18:57:34 +00001058
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001059
Tim Peters4643c2f2006-08-10 22:45:34 +00001060C API
1061-----
1062
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001063- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1064
Tim Peters4643c2f2006-08-10 22:45:34 +00001065- Bug #1069160. Internal correctness changes were made to
1066 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1067 the documentation was changed to state that the return value

1072================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001073
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001074*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001075
1076Core and builtins
1077-----------------
1078
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001079- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001080 returned a long (see PEP 353).
1081
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001082- Bug #1515471: string.replace() accepts character buffers again.
1083
Neal Norwitz07aadb12006-07-30 06:55:48 +00001084- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1085 This provides the proper warning for struct.pack().
1086 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1087
Neal Norwitz0d62a062006-07-30 06:53:31 +00001088- Patch #1531113: Fix augmented assignment with yield expressions.
1089 Also fix a SystemError when trying to assign to yield expressions.
1090
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001091- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1092 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1093 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1094 excessive filesystem operations during imports.
1095
Tim Petersbc24eee2006-07-27 01:14:53 +00001096- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1097 operations on signed longs that are formally undefined by C.
1098 Unfortunately, at least one compiler now cares about that, so complicated
1099 the code to make that compiler happy again.
1100
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001101- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1102
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001103- Patch #1232023: Stop including current directory in search
1104 path on Windows.
1105
Neal Norwitze1fdb322006-07-21 05:32:28 +00001106- Fix some potential crashes found with failmalloc.
1107
Neal Norwitze7563102006-07-17 01:00:16 +00001108- Fix warnings reported by Klocwork's static analysis tool.
1109
Neal Norwitz84be93b2006-07-16 01:50:38 +00001110- Bug #1512814, Fix incorrect lineno's when code within a function
1111 had more than 255 blank lines.
1112
Georg Brandl9dceedb2006-07-12 15:31:17 +00001113- Patch #1521179: Python now accepts the standard options ``--help`` and
1114 ``--version`` as well as ``/?`` on Windows.
1115
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001116- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001117 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001118 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001119
Tim Peters112aad32006-07-19 00:03:19 +00001120- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001121 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001122 new ``sys._current_frames()`` returns a dictionary with one entry,
1123 mapping the faux "thread id" 0 to the current frame.
1124
Ronald Oussoren3075e162006-07-25 20:28:55 +00001125- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001126
Ronald Oussoren3075e162006-07-25 20:28:55 +00001127
Neal Norwitza1f10902006-07-12 07:28:29 +00001128Library
1129-------
1130
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001131- Correction of patch #1455898: In the mbcs decoder, set final=False
1132 for stream decoder, but final=True for the decode function.
1133
Georg Brandl07fec3a2006-08-01 18:49:24 +00001134- os.urandom no longer masks unrelated exceptions like SystemExit or
1135 KeyboardInterrupt.
1136
Tim Peters4643c2f2006-08-10 22:45:34 +00001137- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001138 shutil.copytree on Windows
1139
Georg Brandle34ac7c2006-07-30 11:07:23 +00001140- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1141 refers to file descriptors, not file objects.
1142
Tim Peterscbdd3502006-09-05 01:47:53 +00001143- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001144 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001145 #1513611, and probably others.
1146
Georg Brandledd9b0d2006-07-29 09:33:26 +00001147- Bug #1441397: The compiler module now recognizes module and function
1148 docstrings correctly as it did in Python 2.4.
1149
Tim Peters6f681472006-07-27 23:44:37 +00001150- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1151 lost that tests are sorted by name before being run. This rarely
1152 matters for well-written tests, but can create baffling symptoms if
1153 side effects from one test to the next affect outcomes. ``DocTestFinder``
1154 has been changed to sort the list of tests it returns.
1155
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001156- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001157 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001158
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001159- Bug #978833: Really close underlying socket in _socketobject.close.
1160
Georg Brandldb232dc2006-08-20 13:15:43 +00001161- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1162 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001163
Georg Brandlcf0c1722006-07-26 07:23:32 +00001164- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1165 to recursive calls and call it with the failing package name.
1166
Martin v. Löwis0b483032006-07-25 09:53:12 +00001167- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1168
Georg Brandlc13c34c2006-07-24 14:09:56 +00001169- Patch #1515343: Fix printing of deprecated string exceptions with a
1170 value in the traceback module.
1171
Greg Ward48fae7a2006-07-23 16:05:51 +00001172- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1173
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001174- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1175
Brett Cannoncaebe222006-07-18 04:41:36 +00001176- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1177 argument tuple. For arguments where zero is illegal, the value is forced to
1178 the minimum value that is correct. This is to support an undocumented but
1179 common way people used to fill in inconsequential information in the time
1180 tuple pre-2.4.
1181
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001182- Patch #1220874: Update the binhex module for Mach-O.
1183
Barry Warsawb110bad2006-07-21 14:51:07 +00001184- The email package has improved RFC 2231 support, specifically for
1185 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1186 (name*0=<blah>) parameter continuations. This may change the types of
1187 values returned from email.message.Message.get_param() and friends.
1188 Specifically in some cases where non-encoded continuations were used,
1189 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1190 will just return the string (since non-encoded continuations don't have
1191 charset and language parts).
1192
1193 Also, whereas % values were decoded in all parameter continuations, they are
1194 now only decoded in encoded parameter parts.
1195
Ronald Oussoren3075e162006-07-25 20:28:55 +00001196- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1197
1198- Bug #1517996: IDLE now longer shows the default Tk menu when a
1199 path browser, class browser or debugger is the frontmost window on MacOS X
1200
Barry Warsaw00decd72006-07-27 23:43:15 +00001201- Patch #1520294: Support for getset and member descriptors in types.py,
1202 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1203 of an object against these built-in types and more importantly, for getting
1204 their docstrings printed in the interactive interpreter's help() function.

1208-----------------
1209
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001210- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1211 a socket operation on a socket with a timeout, the exception will be
1212 caught correctly. Previously, the exception was not caught.
1213
Thomas Heller1393d6a2006-07-28 21:43:20 +00001214- Patch #1529514: The _ctypes extension is now compiled on more
1215 openbsd target platforms.
1216
Tim Peters9cab5932006-07-28 00:30:00 +00001217- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1218 a memory leak, affecting pickles and deep copies.
1219
Tim Petersbc24eee2006-07-27 01:14:53 +00001220- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1224
Thomas Hellerce049a02006-07-14 17:51:14 +00001225- Patch #1521817: Index range checking on ctypes arrays containing
1226 exactly one element enabled again. This allows iterating over these
1227 arrays, without the need to check the array size before.
1228
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001229- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001230 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001231 /dev/null in certain cases; this is now fixed.
1232
Thomas Heller47d7a062006-07-12 08:43:47 +00001233- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1234 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001235
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001236- Because of a misspelled preprocessor symbol, ctypes was always
1237 compiled without thread support; this is now fixed.
1238
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001239- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1240 methods now allow their database parameter to be None as the
1241 sleepycat API allows.
1242
Matt Flemingec926502006-07-28 11:27:27 +00001243- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1244 bluetooth API compared with Linux and FreeBSD.
1245
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001246Tests
1247-----
1248
1249- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1250 how long the test file should take to play. Now accepts taking 2.93 secs
1251 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1252
Georg Brandl4793aa32006-07-28 18:31:39 +00001253- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1254 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1255 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +00001256
Martin v. Löwis0907f4d2006-07-30 14:09:47 +00001257Build
1258-----
1259
1260- Bug #1439538: Drop usage of test -e in configure as it is not portable.
1261
Ronald Oussoren26cad082006-08-01 21:00:57 +00001262Mac
1263---
1264
1265- PythonLauncher now works correctly when the path to the script contains
1266 characters that are treated specially by the shell (such as quotes).
1267
1268- Bug #1527397: PythonLauncher now launches scripts with the working directory
1269 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001270 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001271 expect.

1280-----------------
1281
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001282- Bug #1441486: The literal representation of -(sys.maxint - 1)
1283 again evaluates to a int object, not a long.
1284
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001285- Bug #1501934: The scope of global variables that are locally assigned
1286 using augmented assignment is now correctly determined.
1287
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001288- Bug #927248: Recursive method-wrapper objects can now safely
1289 be released.
1290
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001291- Bug #1417699: Reject locale-specific decimal point in float()
1292 and atof().
1293
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001294- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1295 omit a default "error" argument for NULL pointer. This allows
1296 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001297
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001298- Bug #1519018: 'as' is now validated properly in import statements.
1299
Neal Norwitz28746ab2006-07-09 22:14:42 +00001300- On 64 bit systems, int literals that use less than 64 bits are
1301 now ints rather than longs.
1302
Neal Norwitzed657552006-07-10 00:04:44 +00001303- Bug #1512814, Fix incorrect lineno's when code at module scope
1304 started after line 256.
1305
Tim Peters32a83612006-07-10 21:08:24 +00001306- New function ``sys._current_frames()`` returns a dict mapping thread
1307 id to topmost thread stack frame. This is for expert use, and is
1308 especially useful for debugging application deadlocks. The functionality
1309 was previously available in Fazal Majid's ``threadframe`` extension
1310 module, but it wasn't possible to do this in a wholly threadsafe way from
1311 an extension.
1312

Martin v. Löwis8d656812006-07-10 07:23:48 +00001322 environment variable to be set in order to the SDK environment
1323 for finding the compiler, include files, etc.

1328
Thomas Woutersadd19112006-07-05 11:03:49 +00001329- string.Template() now correctly handles tuple-values. Previously,
1330 multi-value tuples would raise an exception and single-value tuples would
1331 be treated as the value they contain, instead.
1332
Martin v. Löwisede77f52006-07-03 13:01:35 +00001333- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1340 degrees and radians.
1341
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001342- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001343 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001344
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001345- Bug #1514703: Only setup canvas window in turtle when the canvas
1346 is created.
1347
Martin v. Löwis7596e832006-07-01 15:33:37 +00001348- Bug #1513223: .close() of a _socketobj now releases the underlying
1349 socket again, which then gets closed as it becomes unreferenced.

1354- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1355 sgmllib ('[' and ']' were not accepted).
1356
Georg Brandl1be63af2006-06-28 20:23:25 +00001357- Fix a bug in the turtle module's end_fill function.
1358
Brett Cannon53ab5b72006-06-22 16:49:14 +00001359- Bug #1510580: The 'warnings' module improperly required that a Warning
1360 category be either a types.ClassType and a subclass of Warning. The proper
1361 check is just that it is a subclass with Warning as the documentation states.
1362
Georg Brandlad29e632006-06-21 17:45:17 +00001363- The compiler module now correctly compiles the new try-except-finally
1364 statement (bug #1509132).
1365
Neal Norwitz60373cd2006-06-22 06:30:50 +00001366- The wsgiref package is now installed properly on Unix.
1367
Vinay Sajip28e57612006-07-01 10:45:20 +00001368- A bug was fixed in logging.config.fileConfig() which caused a crash on
1369 shutdown when fileConfig() was called multiple times.
1370
Gerhard Häring762fbd32006-07-02 17:48:30 +00001371- The sqlite3 module did cut off data from the SQLite database at the first
1372 null character before sending it to a custom converter. This has been fixed
1373 now.
1374
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001375Extension Modules
1376-----------------
1377
Tim Peters112aad32006-07-19 00:03:19 +00001378- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1379 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1380 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001381
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001382- Assigning None to pointer type fields in ctypes structures possible
1383 overwrote the wrong fields, this is fixed now.
1384
1385- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1386 on non-Windows platforms.
1387
1388- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1389 integer or long, without range checking.
1390
1391- Patch #1517790: It is now possible to use custom objects in the ctypes
1392 foreign function argtypes sequence as long as they provide a from_param
1393 method, no longer is it required that the object is a ctypes type.
1394
1395- The '_ctypes' extension module now works when Python is configured
1396 with the --without-threads option.
1397
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001398- Bug #1513646: os.access on Windows now correctly determines write

1413
Tim Peters32a83612006-07-10 21:08:24 +00001414- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001415 Previously, the slight difference could cause compilation errors of the
1416 'zlib' module on systems with more than one version of zlib.
1417
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001418- The MSI compileall step was fixed to also support a TARGETDIR

1437 documentation for the warnings module.
1438
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001439- Patch #1509163: MS Toolkit Compiler no longer available.

1455
Brett Cannonea3912b2006-06-13 21:46:41 +00001456- Bug #992017: A classic class that defined a __coerce__() method that returned
1457 its arguments swapped would infinitely recurse and segfault the interpreter.
1458
Neal Norwitz909eb122006-06-12 02:13:21 +00001459- Fix the socket tests so they can be run concurrently.

Brett Cannon22565aa2006-06-09 22:31:23 +00001464- Bug #532646: object.__call__() will continue looking for the __call__
1465 attribute on objects until one without one is found. This leads to recursion
1466 when you take a class and set its __call__ attribute to an instance of the
1467 class. Originally fixed for classic classes, but this fix is for new-style.
1468 Removes the infinite_rec_3 crasher.
1469
Georg Brandl24250812006-06-09 18:45:48 +00001470- The string and unicode methods startswith() and endswith() now accept
1471 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1472
Brett Cannonde3b0522006-06-08 17:00:45 +00001473- Buffer objects, at the C level, never used the char buffer
1474 implementation even when the char buffer for the wrapped object was
1475 explicitly requested (originally returned the read or write buffer).
1476 Now a TypeError is raised if the char buffer is not present but is
1477 requested.
1478
Georg Brandlddbaa662006-06-04 21:56:52 +00001479- Patch #1346214: Statements like "if 0: suite" are now again optimized
1480 away like they were in Python 2.4.
1481
Georg Brandlb7c8f542006-05-27 12:30:25 +00001482- Builtin exceptions are now full-blown new-style classes instead of
1483 instances pretending to be classes, which speeds up exception handling
1484 by about 80% in comparison to 2.5a2.
1485
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001486- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1487 Unicode 4.1.
1488
Georg Brandlf4ef1162006-05-26 18:03:31 +00001489- Patch #921466: sys.path_importer_cache is now used to cache valid and
1490 invalid file paths for the built-in import machinery which leads to
1491 fewer open calls on startup.
1492
Tim Peters696cf432006-05-24 21:10:40 +00001493- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1494 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1495 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1496 the number of input digits (it was and remains linear-time for bases
1497 2, 4, 8, 16 and 32).
1498
Tim Petersb713ec22006-05-23 18:45:30 +00001499- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1500 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1501 an integer close to ``sys.maxint``. This was repaired by patch
1502 #1335972, which also gives a nice speedup.
1503
Richard Jonescebbefc2006-05-23 18:28:17 +00001504- Patch #1337051: reduced size of frame objects.
1505
1506- PyErr_NewException now accepts a tuple of base classes as its
1507 "base" parameter.
1508
Richard Jones7c88dcc2006-05-23 10:37:38 +00001509- Patch #876206: function call speedup by retaining allocated frame
1510 objects.
1511
Georg Brandl7b90e162006-05-18 07:01:27 +00001512- Bug #1462152: file() now checks more thoroughly for invalid mode
1513 strings and removes a possible "U" before passing the mode to the
1514 C library function.
1515
Neal Norwitz1004a532006-05-15 07:17:23 +00001516- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1517
Neal Norwitz373f0a72006-05-15 07:04:36 +00001518- Bug #1487966: Fix SystemError with conditional expression in assignment
1519
Martin v. Löwis879768d2006-05-11 13:28:43 +00001520- WindowsError now has two error code attributes: errno, which carries
1521 the error values from errno.h, and winerror, which carries the error
1522 values from winerror.h. Previous versions put the winerror.h values
1523 (from GetLastError()) into the errno attribute.
1524
Martin v. Löwis77736712006-05-04 05:51:03 +00001525- Patch #1475845: Raise IndentationError for unexpected indent.
1526
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001527- Patch #1479181: split open() and file() from being aliases for each other.
1528
Tim Peters44bd9862006-06-01 13:49:23 +00001529- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1530 methods were always silently ignored by dictionaries when comparing keys.
1531 They are now passed through (except when using the C API function
1532 ``PyDict_GetItem()``, whose semantics did not change).
1533
1534- Bug #1456209: In some obscure cases it was possible for a class with a
1535 custom ``__eq__()`` method to confuse dict internals when class instances
1536 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1537 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001539Extension Modules
1540-----------------
1541
Trent Mick960a3f82006-06-28 20:30:41 +00001542- Bug #1295808: expat symbols should be namespaced in pyexpat
1543
1544- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1545
Brett Cannon6ee7d012006-06-08 16:23:04 +00001546- Change binascii.hexlify to accept a read-only buffer instead of only a char
1547 buffer and actually follow its documentation.
1548
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001549- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1550
Nick Coghlanc649ec52006-05-29 12:43:05 +00001551- Patch #1478788 (modified version): The functional extension module has
1552 been renamed to _functools and a functools Python wrapper module added.
1553 This provides a home for additional function related utilities that are
1554 not specifically about functional programming. See PEP 309.
1555
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001556- Patch #1493701: performance enhancements for struct module.
1557
Georg Brandl378d5922006-05-17 14:26:50 +00001558- Patch #1490224: time.altzone is now set correctly on Cygwin.
1559
Georg Brandl8d3342b2006-05-16 07:38:27 +00001560- Patch #1435422: zlib's compress and decompress objects now have a
1561 copy() method.
1562
Andrew MacIntyre92913322006-06-13 15:04:24 +00001563- Patch #1454481: thread stack size is now tunable at runtime for thread
1564 enabled builds on Windows and systems with Posix threads support.
1565
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001566- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1567 (up to the system limit of 32K characters).
1568
1569- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1570 As a result, these functions now raise WindowsError instead of OSError.
1571
Tim Peters7a822da2006-05-25 21:50:17 +00001572- ``time.clock()`` on Win64 should use the high-performance Windows
1573 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1574 Windows platforms).
1575
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001576- Calling Tk_Init twice is refused if the first call failed as that
1577 may deadlock.
1578
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001579- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1580 accept it without potentially using an uninitialized pointer.
1581
1582- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1583 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1584 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001585
Gregory P. Smith372b5832006-06-05 18:48:21 +00001586- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001587 [pybsddb project SF patch number 1466734]
1588
Gregory P. Smith372b5832006-06-05 18:48:21 +00001589- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1590 parameter is supplied. [SF pybsddb bug #1477863]
1591
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001592- bsddb: the __len__ method of a DB object has been fixed to return correct
1593 results. It could previously incorrectly return 0 in some cases.
1594 Fixes SF bug 1493322 (pybsddb bug 1184012).
1595
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001596- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1597 aborts the db transaction safely when a modifier callback fails.
1598 Fixes SF python patch/bug #1408584.
1599
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001600- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001601 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001602 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1603 database calls that would previously deadlock. [SF python bug #775414]
1604
Vinay Sajip28e57612006-07-01 10:45:20 +00001605- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001606
Walter Dörwald4994d952006-06-19 08:07:50 +00001607- Patch #1506645: add Python wrappers for the curses functions
1608 is_term_resized, resize_term and resizeterm.

1612
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001613- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1614 functions.
1615
Martin v. Löwis3798da02006-06-17 18:44:27 +00001616- Patch #812986: Update turtle output even if not tracing.
1617
Vinay Sajip28e57612006-07-01 10:45:20 +00001618- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001619 Tkinter.BaseWidget.
1620
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001621- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1622
Martin v. Löwis337487e2006-06-17 09:15:14 +00001623- Patch #763580: Add name and value arguments to Tkinter variable
1624 classes.
1625
Georg Brandl83cc0d02006-06-14 08:50:03 +00001626- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1627 mime.types file for determining MIME types.
1628
Georg Brandl2605ca82006-06-14 06:08:31 +00001629- Bug #1339007: Shelf objects now don't raise an exception in their
1630 __del__ method when initialization failed.
1631
Martin v. Löwisd8251432006-06-14 05:21:04 +00001632- Patch #1455898: The MBCS codec now supports the incremental mode for
1633 double-byte encodings.
1634
Tim Peters43898b42006-06-14 04:09:25 +00001635- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1636 guarantee that adjacent triples in the return list always describe
1637 non-adjacent blocks. Previously, a pair of matching blocks could end
1638 up being described by multiple adjacent triples that formed a partition
1639 of the matching pair.
1640
Greg Ward0e0c9f42006-06-11 16:24:11 +00001641- Bug #1498146: fix optparse to handle Unicode strings in option help,
1642 description, and epilog.
1643
Greg Wardd1c797e2006-06-11 14:42:41 +00001644- Bug #1366250: minor optparse documentation error.
1645
Greg Ward7f547402006-06-11 00:40:49 +00001646- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1647 clarify docs.
1648
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001649- The wsgiref package has been added to the standard library.
1650
Nick Coghlan676725d2006-06-08 13:54:49 +00001651- The functions update_wrapper() and wraps() have been added to the functools
1652 module. These make it easier to copy relevant metadata from the original
1653 function when writing wrapper functions.
1654
Tim Petersd6a9eef2006-06-05 01:48:21 +00001655- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1656 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001657
Martin v. Löwis3f767792006-06-04 19:36:28 +00001658- Patch #1359618: Speed up charmap encoder by using a trie structure
1659 for lookup.
1660
Tim Petersd609b1a2006-06-02 23:22:51 +00001661- The functions in the ``pprint`` module now sort dictionaries by key
1662 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1663 if and only if its display required more than one line, although that
1664 wasn't documented. The new behavior increases predictability; e.g.,
1665 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1666
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001667- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1668 (thanks for J. J. Lee).
1669
Georg Brandl2b330372006-05-28 20:23:12 +00001670- Patch #1496206: improve urllib2 handling of passwords with respect to
1671 default HTTP and HTTPS ports.
1672
George Yoshidaf3c65de2006-05-28 16:39:09 +00001673- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1674
Bob Ippolito7298f272006-05-23 18:43:47 +00001675- Patch #1281707: speed up gzip.readline.
1676
Georg Brandlb89316f2006-05-17 15:51:16 +00001677- Patch #1180296: Two new functions were added to the locale module:
1678 format_string() to get the effect of "format % items" but locale-aware,
1679 and currency() to format a monetary number with currency sign.
1680
Georg Brandle3a25832006-05-17 14:56:04 +00001681- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1682 and several features added, such as speed and geometry control.
1683
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001684- Patch #1488881: add support for external file objects in bz2 compressed
1685 tarfiles.
1686
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001687- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1688 stdout arguments, making it possible to redirect input and output
1689 for remote debugging.
1690
1691- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1692 a couple of issues, notably handling of long file names using the
1693 GNU LONGNAME extension.
1694
1695- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1696 new flag when ``name`` is already the name of an option flag.
1697
1698- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1699 package.
1700
1701- Patch #1472854: make the rlcompleter.Completer class usable on non-
1702 UNIX platforms.
1703
1704- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1705
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001706- Bug #1472827: correctly escape newlines and tabs in attribute values in
1707 the saxutils.XMLGenerator class.

1739
1740*Release date: 27-APR-2006*

1742Core and builtins
1743-----------------
1744
Thomas Heller1b046642006-04-18 18:51:06 +00001745- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1746 by converting these apis from macros into exported functions again:
1747
1748 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1749 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1750 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1751 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1752 PyRun_String Py_CompileString
1753
Martin v. Löwis45294a92006-04-18 06:24:08 +00001754- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1755
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001756- All uses of PyStructSequence_InitType have been changed to initialize
1757 the type objects only once, even if the interpreter is initialized
1758 multiple times.
1759
Neal Norwitz61546162006-04-14 05:20:28 +00001760- Bug #1454485, array.array('u') could crash the interpreter. This was
1761 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1762 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1763
1764- Py_UNICODE is unsigned. It was always documented as unsigned, but
1765 due to a bug had a signed value in previous versions.
1766
Tim Peters3a5e8b12006-04-11 01:44:07 +00001767- Patch #837242: ``id()`` of any Python object always gives a positive
1768 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1769 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001770 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001771 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001772
Tim Peters3a5e8b12006-04-11 01:44:07 +00001773 def __hash__(self):
1774 return id(self) # WRONG
1775
1776 because a hash result must be a (short) Python int but it was always
1777 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001778 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001779 was always usable as a hash value before this patch. That's no longer
1780 necessarily so.
1781
1782- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001783 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001784 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001785 #1454844)
1786
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001787- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1788 involving generators that have paused outside of any ``try`` or ``with``
1789 blocks. (In 2.5a1, a paused generator that was part of a reference
1790 cycle could not be garbage collected, regardless of whether it was
1791 paused in a ``try`` or ``with`` block.)

1805 the cachesize parameter.
1806
1807- Bug #1149413: bsddb.*open() no longer raises an exception when using
1808 a temporary db (file=None) with the 'n' flag to truncate on open.
1809
1810- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1811 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001812
Armin Rigoa9017c32006-04-19 11:50:27 +00001813- Patch #1062014: AF_UNIX sockets under Linux have a special

1820 of the process using the returncode attribute, instead of
1821 abusing errno.
1822
Tim Peters711bf302006-04-25 03:31:36 +00001823- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1824 a doctest to be skipped (the code is not run, and the expected output
1825 or exception is ignored).
1826
Nick Coghlanda2268f2006-04-24 04:37:15 +00001827- Fixed contextlib.nested to cope with exceptions being raised and
1828 caught inside exit handlers.
1829
Greg Wardab05edc2006-04-23 03:47:58 +00001830- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1831 hex, octal, or binary; add ``append_const`` action; keep going if
1832 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1833 added ``epilog`` for better help generation).
1834
Tim Peters21fbd572006-04-21 21:18:10 +00001835- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1836 called from a thread spawned as a side effect of importing a module.
1837
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001838- The pydoc module now supports documenting packages contained in
1839 .zip or .egg files.
1840
1841- The pkgutil module now has several new utility functions, such
1842 as ``walk_packages()`` to support working with packages that are either
1843 in the filesystem or zip files.
1844
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001845- The mailbox module can now modify and delete messages from
1846 mailboxes, in addition to simply reading them. Thanks to Gregory
1847 K. Johnson for writing the code, and to the 2005 Google Summer of
1848 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001849
Tim Petersc7605f22006-04-17 21:12:33 +00001850- The ``__del__`` method of class ``local`` in module ``_threading_local``

1872
Skip Montanaro262fb922006-04-21 02:31:07 +00001873- The pstats.Stats class accepts an optional stream keyword argument to
1874 direct output to an alternate file-like object.
1875
Anthony Baxter51bcb682006-04-05 14:51:42 +00001876Build
1877-----
1878
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001879- The Makefile now has a reindent target, which runs reindent.py on
1880 the library.
1881
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001882- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001885
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001886- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1887 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001888 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001889 CXX from --with-cxx-main, see description in README.
1890
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001891- Patch #1429775: Link extension modules with the shared libpython.
1892
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001893- Fixed a libffi build problem on MIPS systems.
1894
Tim Peters8931ff12006-05-13 23:28:20 +00001895- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1896 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1897 and "%zu" for unsigned integers of type ``size_t``.
1898
Anthony Baxter51bcb682006-04-05 14:51:42 +00001899Tests
1900-----
1901
Nick Coghlanda2268f2006-04-24 04:37:15 +00001902- test_contextlib now checks contextlib.nested can cope with exceptions
1903 being raised and caught inside exit handlers.
1904
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001905- test_cmd_line now checks operation of the -m and -c command switches
1906
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001907- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1908 it separately and by hand. It also wasn't cleaning up its changes to
1909 the current Decimal context.
1910
Thomas Woutersabd08882006-04-26 15:53:30 +00001911- regrtest.py now has a -M option to run tests that test the new limits of
1912 containers, on 64-bit architectures. Running these tests is only sensible
1913 on 64-bit machines with more than two gigabytes of memory. The argument
1914 passed is the maximum amount of memory for the tests to use.

1923-------------
1924
Tim Petersb06d28c2006-05-12 01:57:59 +00001925- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1926
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001927- PEP 343: Added Context Types section to the library reference
1928 and attempted to bring other PEP 343 related documentation into
1929 line with the implementation and/or python-dev discussions.
1930
Tim Peters8dc73d22006-04-24 02:03:16 +00001931- Bug #1337990: clarified that ``doctest`` does not support examples
1932 requiring both expected output and an exception.

1936=================================
1937
Anthony Baxterebed3f62006-04-03 15:03:44 +00001938*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001939
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001940Core and builtins
1941-----------------
1942
Nick Coghlan43832302006-04-23 17:04:07 +00001943- PEP 338: -m command line switch now delegates to runpy.run_module
1944 allowing it to support modules in packages and zipfiles
1945
Martin v. Löwisc661b882006-04-20 04:54:23 +00001946- On Windows, .DLL is not an accepted file name extension for
1947 extension modules anymore; extensions are only found if they
1948 end in .PYD.
1949
Martin v. Löwisea62d252006-04-03 10:56:49 +00001950- Bug #1421664: sys.stderr.encoding is now set to the same value as
1951 sys.stdout.encoding.
1952
Neal Norwitz92e212f2006-04-03 04:48:37 +00001953- __import__ accepts keyword arguments.
1954
Georg Brandlccadf842006-03-31 18:54:53 +00001955- Patch #1460496: round() now accepts keyword arguments.
1956
Anthony Baxter262c00a2006-03-30 10:53:17 +00001957- Fixed bug #1459029 - unicode reprs were double-escaped.
1958
Hye-Shik Changd478f342006-03-23 12:32:36 +00001959- Patch #1396919: The system scope threads are reenabled on FreeBSD
1960 5.4 and later versions.
1961
Neal Norwitze98ccf62006-03-23 05:39:47 +00001962- Bug #1115379: Compiling a Unicode string with an encoding declaration
1963 now gives a SyntaxError.
1964
Georg Brandlabd1ff82006-03-18 07:59:59 +00001965- Previously, Python code had no easy way to access the contents of a
1966 cell object. Now, a ``cell_contents`` attribute has been added
1967 (closes patch #1170323).
1968
Tim Peterscf79aac2006-03-16 01:14:46 +00001969- Patch #1123430: Python's small-object allocator now returns an arena to
1970 the system ``free()`` when all memory within an arena becomes unused
1971 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1972 freed. Some applications will see a drop in virtual memory size now,
1973 especially long-running applications that, from time to time, temporarily
1974 use a large number of small objects. Note that when Python returns an
1975 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001976 platform C library will in turn return that memory to the operating system.
1977 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001978 appears to be effective at least on Microsoft C and gcc-based systems.
1979 Thanks to Evan Jones for hard work and patience.
1980
Georg Brandl533ff6f2006-03-08 18:09:27 +00001981- Patch #1434038: property() now uses the getter's docstring if there is
1982 no "doc" argument given. This makes it possible to legitimately use
1983 property() as a decorator to produce a read-only property.
1984
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001985- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1986 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1987 of requiring an int or long in slicing and a few other contexts, enabling
1988 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1989
Neal Norwitz995acdf2006-03-07 05:01:00 +00001990- Fixed various bugs reported by Coverity's Prevent tool.
1991
Brett Cannonbf364092006-03-01 04:25:17 +00001992- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1993 new exception base class, BaseException, which has a new message attribute.
1994 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1995 Raising a string exception now raises a DeprecationWarning.
1996
Thomas Woutersfb609f42006-02-28 16:37:25 +00001997- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1998 explicitly relative, using 'from .module import name' to mean 'from the same
1999 package as this module is in. Imports without dots still default to the
2000 old relative-then-absolute, unless 'from __future__ import
2001 absolute_import' is used.
2002
Brett Cannona7446e32006-02-27 23:39:10 +00002003- Properly check if 'warnings' raises an exception (usually when a filter set
2004 to "error" is triggered) when raising a warning for raising string
2005 exceptions.
2006
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002007- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002008 The name was removed from Include/code.h.
2009
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002010- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002011
Guido van Rossum1968ad32006-02-25 22:38:04 +00002012- Patch 1433928:
2013 - The copy module now "copies" function objects (as atomic objects).
2014 - dict.__getitem__ now looks for a __missing__ hook before raising
2015 KeyError.
2016
Tim Peters84ef21c2006-02-28 20:39:06 +00002017- PEP 343: with statement implemented. Needs ``from __future__ import
2018 with_statement``. Use of 'with' as a variable will generate a warning.
2019 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002020 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002021 The following objects have __context__ methods:
2022 - The built-in file type.
2023 - The thread.LockType type.
2024 - The following types defined by the threading module:
2025 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2026 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002027
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002028- Fix the encodings package codec search function to only search
2029 inside its own package. Fixes problem reported in patch #1433198.
2030
2031 Note: Codec packages should implement and register their own
2032 codec search function. PEP 100 has the details.
2033
Tim Peters9ea89d22006-06-04 03:26:02 +00002034- PEP 353: Using ``Py_ssize_t`` as the index type.
2035
2036- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2037 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2038 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2039 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2040 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002041
Neal Norwitzfc76d632006-01-10 06:03:13 +00002042- Patch #1400181, fix unicode string formatting to not use the locale.
2043 This is how string objects work. u'%f' could use , instead of .
2044 for the decimal point. Now both strings and unicode always use periods.
2045
Neal Norwitz671b9e32006-01-09 07:07:12 +00002046- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2047 configure would break checking curses.h.
2048
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002049- Bug #959576: The pwd module is now builtin. This allows Python to be
2050 built on UNIX platforms without $HOME set.
2051
Neal Norwitzc10978f2005-12-19 06:07:16 +00002052- Bug #1072182, fix some potential problems if characters are signed.
2053
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002054- Bug #889500, fix line number on SyntaxWarning for global declarations.
2055
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002056- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.

Neal Norwitze7214a12005-12-18 05:03:17 +00002058- Support for converting hex strings to floats no longer works.
2059 This was not portable. float('0x3') now raises a ValueError.
2060
Barry Warsaw2a38a862005-12-18 01:27:35 +00002061- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002062 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002063 is now displayed in interactive prompt banner.
2064
Georg Brandlfa166682005-12-17 21:45:17 +00002065- Implementation of PEP 341 - Unification of try/except and try/finally.
2066 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002067 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002068
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002069- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2070 now encodes backslash correctly.
2071
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002072- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2073
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002074- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002075 and long longs.
2076
Neal Norwitz67715f02005-11-09 06:59:35 +00002077- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002078 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002079 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002080
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002081- Replaced most Unicode charmap codecs with new ones using the
2082 new Unicode translate string feature in the builtin charmap
2083 codec; the codecs were created from the mapping tables available
2084 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2085 encodings now include a mapping for the Apple logo)
2086
Tim Peterse3547fd2005-12-16 23:13:57 +00002087- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002088
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002089- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002090
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002091- A new AST parser implementation was completed. The abstract
2092 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002093 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002094
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002095- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002096 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2097
Neal Norwitz708e51a2005-10-03 04:48:15 +00002098- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2099
Neal Norwitz11bd1192005-10-03 00:54:56 +00002100- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2101 Provide a warning when a directory is passed on the command line.
2102
Neal Norwitz40d37812005-10-02 01:48:49 +00002103- Fix segfault with invalid coding.
2104
2105- SF bug #772896: unknown encoding results in MemoryError.
2106
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002107- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002108 supported a __len__() method which evaluated to False when the iterator
2109 was empty.
2110
Guido van Rossum630db602005-09-20 18:49:54 +00002111- On 64-bit platforms, when __len__() returns a value that cannot be
2112 represented as a C int, raise OverflowError.
2113
Skip Montanarof8948ca2005-09-19 03:54:46 +00002114- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002115 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002116
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002117- SF bug #893549: parsing keyword arguments was broken with a few format
2118 codes.
2119
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002120- Changes donated by Elemental Security to make it work on AIX 5.3
2121 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2122 bug #105470: test_pwd fails on 64bit system (Opteron).
2123
Guido van Rossum539c6622005-09-14 17:49:54 +00002124- Changes donated by Elemental Security to make it work on HP-UX 11 on
2125 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2126
Georg Brandl4550b8d2005-08-26 06:43:52 +00002127- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002128 (fixes bug #1119418).
2129
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002130- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2131
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002132- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2133 exceptions that cause a function to exit.
2134
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002135- The implementation of set() and frozenset() was revised to use its
2136 own internal data structure. Memory consumption is reduced by 1/3
2137 and there are modest speed-ups as well. The API is unchanged.
2138
Tim Petersde7990b2005-07-17 23:45:23 +00002139- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2140
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002141- SF bug #1229429: PyObject_CallMethod failed to decrement some
2142 reference counts in some error exit cases.
2143
Tim Petersecc6e6a2005-07-10 22:30:55 +00002144- SF bug #1185883: Python's small-object memory allocator took over
2145 a block managed by the platform C library whenever a realloc specified
2146 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002147 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002148 portable way to copy data from the C-managed block into Python's
2149 small-object space without risking a memory fault. Python's small-object
2150 realloc now leaves such blocks under the control of the platform C
2151 realloc.
2152
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002153- SF bug #1232517: An overflow error was not detected properly when
2154 attempting to convert a large float to an int in os.utime().
2155
Raymond Hettinger3296e692005-06-29 23:29:56 +00002156- SF bug #1224347: hex longs now print with lowercase letters just
2157 like their int counterparts.
2158
Michael W. Hudson188d4362005-06-20 16:52:57 +00002159- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2160 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2161 interpreter states; back out that fix and do a better job (see
2162 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2163 for a longer write-up of the problem).
2164
Michael W. Hudsondf888462005-06-03 14:41:55 +00002165- SF patch #1180995: marshal now uses a binary format by default when
2166 serializing floats.
2167
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002168- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2169 the routines that promise to produce IEEE 754 binary representations
2170 of floats now simply copy bytes around.
2171
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002172- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2173 278.
2174
Brett Cannonc3647ac2005-04-26 03:45:26 +00002175- patch #1109424: int, long, float, complex, and unicode now check for the
2176 proper magic slot for type conversions when subclassed. Previously the
2177 magic slot was ignored during conversion. Semantics now match the way
2178 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002179 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002180 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002181 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002182
Barry Warsawc8d907c2005-04-19 23:43:40 +00002183- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2184 NULL, now raise an AttributeError when attempting to set or delete the
2185 attribute. Previously a TypeError was raised, but this was inconsistent
2186 with the equivalent pure-Python implementation.
2187
Michael W. Hudson774479c2005-04-18 08:46:17 +00002188- It is now safe to call PyGILState_Release() before
2189 PyEval_InitThreads() (note that if there is reason to believe there
2190 are multiple threads around you still must call PyEval_InitThreads()
2191 before using the Python API; this fix is for extension modules that
2192 have no way of knowing if Python is multi-threaded yet).
2193
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002194- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2195 disabled caused a crash.
2196
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002197- Bug #1165306: instancemethod_new allowed the creation of a method
2198 with im_class == im_self == NULL, which caused a crash when called.
2199
Tim Petersecc6e6a2005-07-10 22:30:55 +00002200- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002201 fixes the crash seen in bug #1165761
2202
Raymond Hettinger96229b12005-03-11 06:49:40 +00002203- Added two new builtins, any() and all().
2204
Brett Cannon409d8f22005-03-05 06:47:57 +00002205- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002206 (e.g., ``class C(): pass`` is no longer a syntax error).
2207 Patch #1176012 added support to the 'parser' module and 'compiler' package
2208 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002209
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002210- Patch #1115086: Support PY_LONGLONG in structmember.
2211
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002212- Bug #1155938: new style classes did not check that __init__() was
2213 returning None.
2214
Tim Petersecc6e6a2005-07-10 22:30:55 +00002215- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002216 ('\') with a specific error message.
2217
Martin v. Löwisff232d72005-03-03 09:24:38 +00002218- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2219
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002220- Bug #1124295: the __name__ attribute of file objects was
2221 inadvertently made inaccessible in restricted mode.
2222
Tim Petersecc6e6a2005-07-10 22:30:55 +00002223- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002224 an ferror() call.
2225
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002226- min() and max() now support key= arguments with the same meaning as in
2227 list.sort().
2228
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002229- The peephole optimizer now performs simple constant folding in expressions:
2230 (2+3) --> (5).
2231
Raymond Hettingera422c342005-01-11 03:03:27 +00002232- set and frozenset objects can now be marshalled. SF #1098985.
2233
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002234- Bug #1077106: Poor argument checking could cause memory corruption
2235 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002236
Jeremy Hyltonab630502005-02-04 18:44:06 +00002237- The parser did not complain about future statements in illegal
2238 positions. It once again reports a syntax error if a future
2239 statement occurs after anything other than a doc string.
2240
Neil Schemenauercf52c072005-08-12 17:34:58 +00002241- Change the %s format specifier for str objects so that it returns a
2242 unicode instance if the argument is not an instance of basestring and
2243 calling __str__ on the argument returns a unicode instance.
2244
Tim Petersf4e69282006-02-27 17:15:31 +00002245- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2246 current thread state when the auto-GIL-state machinery knows about
2247 it (since the thread state is being deleted, continuing to remember it
2248 can't help, but can hurt if another thread happens to get created with
2249 the same thread id).
2250
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002251Extension Modules
2252-----------------
2253
Georg Brandl43f08a82006-03-31 18:01:16 +00002254- Patch #1380952: fix SSL objects timing out on consecutive read()s

Georg Brandlbc45a3f2006-03-17 19:17:34 +00002263
Neal Norwitz10be10c2006-03-16 06:50:13 +00002264- Everything under lib-old was removed. This includes the following modules:
2265 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00002266 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00002267 util, whatsound, whrandom, zmod
2268
2269- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2270
2271- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002272 is deprecated. The undocumented re.engine variable no longer exists.
2273
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002274- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2275 SS2 (single-shift 2) escape sequences correctly.
2276
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002277- The unicodedata module was updated to the 4.1 version of the Unicode
2278 database. The 3.2 version is still available as unicodedata.db_3_2_0
2279 for applications that require this specific version (such as IDNA).
2280
Neal Norwitzb62c4332006-03-04 18:35:47 +00002281- The timing module is no longer built by default. It was deprecated
2282 in PEP 4 in Python 2.0 or earlier.
2283
Guido van Rossum1968ad32006-02-25 22:38:04 +00002284- Patch 1433928: Added a new type, defaultdict, to the collections module.
2285 This uses the new __missing__ hook behavior added to dict (see above).
2286
Georg Brandldbd83392006-02-20 09:42:33 +00002287- Bug #854823: socketmodule now builds on Sun platforms even when
2288 INET_ADDRSTRLEN is not defined.
2289
Georg Brandlf4f44152006-02-18 22:29:33 +00002290- Patch #1393157: os.startfile() now has an optional argument to specify
2291 a "command verb" to invoke on the file.
2292
Neal Norwitz082b2df2006-02-07 07:04:46 +00002293- Bug #876637, prevent stack corruption when socket descriptor
2294 is larger than FD_SETSIZE.
2295
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00002296- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
2297 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
2298 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
2299
Martin v. Löwis57a34e82006-02-04 19:12:37 +00002300- Patch #1422385: The nis module now supports access to domains other
2301 than the system default domain.
2302
Martin v. Löwis14694662006-02-03 12:54:16 +00002303- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2304 are reported, the limit on path name lengths is removed, and stat reports
2305 WindowsError now (instead of OSError).
2306
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002307- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.
2308
Neal Norwitz62a21122006-01-25 05:21:55 +00002309- Bug #1413192, fix seg fault in bsddb if a transaction was deleted
2310 before the env.
2311
Martin v. Löwis11017b12006-01-14 18:12:57 +00002312- Patch #1103116: Basic AF_NETLINK support.
2313
Neal Norwitz3b4fff82006-01-11 08:54:45 +00002314- Bug #1402308, (possible) segfault when using mmap.mmap(-1, ...)

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002441- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2442 been renamed to have only a single underscore prefix. This was done to
2443 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002444
Nick Coghlan43832302006-04-23 17:04:07 +00002445- PEP 338: new module runpy defines a run_module function to support
2446 executing modules which provide access to source code or a code object
2447 via the PEP 302 import mechanisms.
2448
Anthony Baxter93f5b932006-04-03 08:05:07 +00002449- The email module's parsedate_tz function now sets the daylight savings

2457 in attribute values.
2458
Anthony Baxterc51ee692006-04-01 00:57:31 +00002459- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002460 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002461 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002462 module will not be built.
2463
Tim Petersc17976e2006-04-01 00:26:53 +00002464- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2465 aren't officially supported here, and trying to use them will probably
2466 raise an exception some day. But dicts have been allowed, and "mostly
2467 worked", so support for them won't go away without warning.
2468
Georg Brandl338ef7d2006-03-31 18:42:16 +00002469- Bug #1445068: getpass.getpass() can now be given an explicit stream

2487
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002488- email 4.0 package now integrated. This is largely the same as the email 3.0
2489 package that was included in Python 2.3, except that PEP 8 module names are
2490 now used (e.g. mail.message instead of email.Message). The MIME classes
2491 have been moved to a subpackage (e.g. email.mime.text instead of
2492 email.MIMEText). The old names are still supported for now. Several
2493 deprecated Message methods have been removed and lots of bugs have been
2494 fixed. More details can be found in the email package documentation.
2495
Walter Dörwald40108c92006-03-27 08:15:44 +00002496- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2497 (a subclass of tuple) that provides incremental decoders and encoders
2498 (a way to use stateful codecs without the stream API). Python functions
2499 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2500 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2501 have been added.

2504 a ValueError instead of a StopIteration now (like file and cString.String do).
2505 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2506 called before (like file and StringIO.StringIO do).

Tim Peterse3547fd2005-12-16 23:13:57 +00002580 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2581 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2582 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2583 Ronald L. Rivest offered this advice for Python:
2584
2585 "The consensus of researchers in this area (at least as
2586 expressed at the NIST Hash Function Workshop 10/31/05),
2587 is that SHA-256 is a good choice for the time being, but
2588 that research should continue, and other alternatives may
2589 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002590

2644 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002645 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002646

2684 Bug #1224621.
2685
Raymond Hettinger68c04532005-06-10 11:05:19 +00002686- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002687 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002688 the generate_tokens() function now accepts a callable argument that
2689 terminates by raising StopIteration.
2690
Georg Brandl9166e1a2005-06-04 09:20:03 +00002691- Bug #1196315: fix weakref.WeakValueDictionary constructor.

2699 class at all.
2700
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002701- distutils.commands.upload was added to support uploading distribution

2705 them to PyPI.
2706
Raymond Hettinger267b8682005-03-27 10:47:39 +00002707- decimal operator and comparison methods now return NotImplemented
2708 instead of raising a TypeError when interacting with other types. This
2709 allows other classes to implement __radd__ style methods and have them
2710 work as expected.
2711
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002712- Bug #1163325: Decimal infinities failed to hash. Attempting to
2713 hash a NaN raised an InvalidOperation instead of a TypeError.
2714
Tim Petersecc6e6a2005-07-10 22:30:55 +00002715- Patch #918101: Add tarfile open mode r|* for auto-detection of the

2749
Guido van Rossumd0641422005-02-03 15:01:24 +00002750- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2751 disables recursive traversal through instance attributes, which can
2752 be exploited in various ways.
2753
Tim Peterse3547fd2005-12-16 23:13:57 +00002754- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002755 flags on the HTTP listening socket.
2756
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002757- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2758 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2759
Fred Drakefbdeaad2006-07-29 16:56:15 +00002760- Patches #893642, #1039083: add allow_none, encoding arguments to
2761 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002762

2766
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002767- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2768
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002769- Enhancements to the csv module:
2770
2771 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002772 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002773 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002774 + Dialect parameter parsing has been re-implemented to improve error
2775 reporting.
2776 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2777 dictates.
2778 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002779 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002780 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002781 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2782 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002783 + reader now allows \r characters to be quoted (previously it only allowed
2784 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002785 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002786 + Dialect classes passed to the module are no longer instantiated by
2787 the module before being parsed (the former validation scheme required
2788 this, but the mechanism was unreliable).
2789 + The dialect registry now contains instances of the internal
2790 C-coded dialect type, rather than references to python objects.
2791 + the internal c-coded dialect type is now immutable.
2792 + register_dialect now accepts the same keyword dialect specifications
2793 as the reader and writer, allowing the user to register dialects
2794 without first creating a dialect class.
2795 + a configurable limit to the size of parsed fields has been added -
2796 previously, an unmatched quote character could result in the entire
2797 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002798 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002799 the parser field size limit (returning the former limit). The initial
2800 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002801 + A line_num attribute has been added to the reader object, which tracks
2802 the number of lines read from the source iterator. This is not
2803 the same as the number of records returned, as records can span
2804 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002805 + reader and writer objects were not being registered with the cyclic-GC.
2806 This has been fixed.
2807
Brett Cannone6539c42005-01-08 02:43:53 +00002808- _DummyThread objects in the threading module now delete self.__block that is
2809 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2810 lock primitives tend to be limited in number and thus should not be wasted on
2811 a _DummyThread object. Fixes bug #1089632.
2812
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002813- The imghdr module now detects Exif files.
2814
Raymond Hettinger6065d322004-12-20 23:51:53 +00002815- StringIO.truncate() now correctly adjusts the size attribute.
2816 (Bug #951915).
2817
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002818- locale.py now uses an updated locale alias table (built using
2819 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2820 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002821 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002822
Raymond Hettinger3557f422004-12-07 12:02:02 +00002823- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2824
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002825- the pickle module no longer accepts the deprecated None option in the
2826 args tuple returned by __reduce__().
2827
Brett Cannon84667c02004-12-07 03:25:18 +00002828- optparse now optionally imports gettext. This allows its use in setup.py.
2829
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002830- the pickle module no longer uses the deprecated bin parameter.
2831
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002832- the shelve module no longer uses the deprecated binary parameter.
2833
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002834- the pstats module no longer uses the deprecated ignore() method.
2835
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002836- the filecmp module no longer uses the deprecated use_statcache argument.
2837
Raymond Hettinger664347b2004-12-04 21:21:53 +00002838- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2839 extended or overridden by subclasses. Formerly, the subclassed method would
2840 be ignored by the rest of the module. (Bug #1078905).
2841
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002842- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002843 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002844
Walter Dörwald36733692004-12-22 12:50:50 +00002845- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2846 once when a size argument is given. This prevents a buffer overflow in the
2847 tokenizer with very long source lines.
2848
Barry Warsaw538561e2006-01-01 21:48:54 +00002849- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2850 immediately after creating the object, without any intervening
2851 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002852
Skip Montanaro05885812005-01-16 20:48:27 +00002853- The reconvert.quote function can now emit triple-quoted strings. The
2854 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002855
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002856- ``UserString.MutableString`` now supports negative indices in
2857 ``__setitem__`` and ``__delitem__``
2858
Greg Ward40407942005-03-05 02:53:17 +00002859- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2860 correctly.
2861
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002862- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2863 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2864 character even if the user has passed a size parameter to get a proper
2865 line ending. Remove the special handling of a "\r\n" that has been split
2866 between two lines.
2867
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002868- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2869 about illegal code points. The codec now supports PEP 293 style error
2870 handlers.
2871
Walter Dörwald78a78b02005-09-01 12:04:29 +00002872- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002873 from the input stream, so that the output is a byte string in the correct
2874 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002875
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002876- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2877 considering it exactly like a '*'.
2878
Walter Dörwald007f8df2005-10-09 19:42:27 +00002879- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2880 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002881
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002882- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2883
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002884- Patch #1413711: Certain patterns of differences were making difflib
2885 touch the recursion limit.
2886
Walter Dörwald58917a62006-03-31 15:26:22 +00002887- Bug #947906: An object oriented interface has been added to the calendar
2888 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002889 called as a script (e.g. via ``python -mcalendar``). Localized month and
2890 weekday names can be ouput (even if an exotic encoding is used) using
2891 special classes that use unicode.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002893Build
2894-----
2895
Neal Norwitz602d3392006-03-31 08:21:40 +00002896- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2897 by using -mieee gcc option.
2898

2900
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002901- Build support for Win64-AMD64 was added.
2902
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002903- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2904
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002905- Patch #881820: look for openpty and forkpty also in libbsd.
2906
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002907- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2908 The zlib module is now builtin on Windows.
2909
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002910- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2911
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002912- Bug #1189330: configure did not correctly determine the necessary
2913 value of LINKCC if python was built with GCC 4.0.
2914
Trent Mick8321b422005-07-26 02:29:21 +00002915- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2916 vulnerability in zlib 1.2.1 and 1.2.2.
2917
Brett Cannon08cd5982005-04-24 22:26:38 +00002918- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2919 flags that change binary compatibility. Changes were also made to
2920 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002921 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002922
Bob Ippolitoed233462005-03-29 13:47:59 +00002923- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2924 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2925 no longer exists). This configure patch makes things right.
2926
Martin v. Löwise2713be2005-03-08 15:03:08 +00002927- Bug #1158607: Build with --disable-unicode again.
2928
Brett Cannon46d96232005-02-16 00:07:19 +00002929- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2930 defined. Discovered as a result of not being able to build on OS X.
2931
Brett Cannon516592f2004-12-07 00:42:59 +00002932- setup.py now uses the directories specified in LDFLAGS using the -L option
2933 and in CPPFLAGS using the -I option for adding library and include
2934 directories, respectively, for compiling extension modules against. This has
2935 led to the core being compiled using the values in CPPFLAGS. It also removes
2936 the need for the special-casing of both DarwinPorts and Fink for darwin since
2937 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2938 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2939 Fink, ``-I/opt/local/include`` for DarwinPorts).
2940
Brett Cannon43802422005-02-10 20:48:03 +00002941- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2942 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2943 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2944 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002946C API
2947-----
2948
Tim Petersc9d78aa2006-03-26 23:27:58 +00002949- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2950 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2951 is obtained via the ``PyObject_`` family, it must be released via the
2952 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2953 always been officially true, but when Python's small-object allocator was
2954 introduced, an attempt was made to cater to a few extension modules
2955 discovered at the time that obtained memory via ``PyObject_New`` but
2956 released it via ``PyMem_DEL``. It's years later, and if such code still
2957 exists it will fail now (probably with segfaults, but calling wrong
2958 low-level memory management functions can yield many symptoms).
2959
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002960- Added a C API for set and frozenset objects.
2961
Raymond Hettinger66517482004-12-03 11:45:13 +00002962- Removed PyRange_New().
2963
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002964- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2965 mapping argument now. This string is used as a mapping table. Byte values
2966 greater than the length of the string and 0xFFFE are treated as undefined
2967 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00002973- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002974
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002975- Patch #1276356: New resource "urlfetch" is implemented. This enables
2976 even impatient people to run tests that require remote files.
