Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000887 Instead, the equal (==) and unequal (!=) comparison operators will
888 now issue a UnicodeWarning and interpret the two objects as
889 unequal. The UnicodeWarning can be filtered as desired using
890 the warning framework, e.g. silenced completely, turned into an
891 exception, logged, etc.
892
893 Note that compare operators other than equal and unequal will still
894 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000895
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000896- Fix segfault when doing string formatting on subclasses of long.
897
898- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
899 with new-style classes.
900
901- Fix bug related to __len__ functions returning negative values with
902 classic classes.
903
904- Patch #1538606, Fix __index__() clipping. There were some problems
905 discovered with the API and how integers that didn't fit into Py_ssize_t
906 were handled. This patch attempts to provide enough alternatives
907 to effectively use __index__.
908
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000909- Bug #1536021: __hash__ may now return long int; the final hash
910 value is obtained by invoking hash on the long int.
911
Thomas Hellerab1049c2006-08-08 17:37:00 +0000912- Bug #1536786: buffer comparison could emit a RuntimeWarning.
913
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000914- Bug #1535165: fixed a segfault in input() and raw_input() when
915 sys.stdin is closed.
916
Thomas Heller74d36f02006-08-04 18:17:40 +0000917- On Windows, the PyErr_Warn function is now exported from
918 the Python dll again.
919
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000920- Bug #1191458: tracing over for loops now produces a line event
921 on each iteration. Fixing this problem required changing the .pyc
922 magic number. This means that .pyc files generated before 2.5c1
923 will be regenerated.
924
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000925- Bug #1333982: string/number constants were inappropriately stored
926 in the byte code and co_consts even if they were not used, ie
927 immediately popped off the stack.
928
Georg Brandle9462c72006-08-04 18:03:37 +0000929- Fixed a reference-counting problem in property().
930
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000931
932Library
933-------
934
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000935- Fix a bug in the ``compiler`` package that caused invalid code to be
936 generated for generator expressions.
937
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000938- The distutils version has been changed to 2.5.0. The change to
939 keep it programmatically in sync with the Python version running
940 the code (introduced in 2.5b3) has been reverted. It will continue
941 to be maintained manually as static string literal.
942
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000943- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000944 and this cannot be converted to the required C type, an exception is
945 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000946 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000947
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000948- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000949 an exception.
950
Tim Peterscbdd3502006-09-05 01:47:53 +0000951- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000952 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000953 workarounds for clocks with low resolution, to stop the code yielding
954 duplicate UUIDs.
955
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000956- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
957 before raising SystemExit, allowing IDLE to honor quit() and exit().
958
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000959- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
960
Georg Brandl7a1af772006-08-14 21:55:28 +0000961- Patch #1536071: trace.py should now find the full module name of a
962 file correctly even on Windows.
963
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000964- logging's atexit hook now runs even if the rest of the module has
965 already been cleaned up.
966
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000967- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000968
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000969- Bug #1531405, format_exception no longer raises an exception if
970 str(exception) raised an exception.
971
Neil Schemenauer06ded092006-08-04 16:20:30 +0000972- Fix a bug in the ``compiler`` package that caused invalid code to be
973 generated for nested functions.
974
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000975
976Extension Modules

Neal Norwitzbf8c1952006-08-15 04:14:57 +0000981- Patch #1511317: don't crash on invalid hostname (alias) info.
982
Georg Brandl3335a7a2006-08-14 21:42:55 +0000983- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
984 raises the correct exceptions.
985
Thomas Heller1ce433e2006-08-14 16:20:04 +0000986- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
987 '-no-stack-protector' compiler flag for OpenBSD has been removed.
988
Thomas Heller86720042006-08-14 11:17:48 +0000989- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
990 uses the _as_parameter_ attribute when objects are passed to foreign
991 function calls. The ctypes version number was changed to 1.0.1.
992
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000993- Bug #1530559, struct.pack raises TypeError where it used to convert.
994 Passing float arguments to struct.pack when integers are expected
995 now triggers a DeprecationWarning.
996
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000997

Neal Norwitz003c9e22006-08-11 06:09:41 +00001004- test_mailbox should now work on cygwin versions 2006-08-10 and later.
1005
Georg Brandl9908d162006-08-06 07:06:33 +00001006- Bug #1535182: really test the xreadlines() method of bz2 objects.
1007
Andrew MacIntyre16ee33a2006-08-06 12:37:03 +00001008- test_threading now skips testing alternate thread stack sizes on
1009 platforms that don't support changing thread stack size.

1019-----
1020
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +00001021- Bug #1535502, build _hashlib on Windows, and use masm assembler
1022 code in OpenSSL.
1023
Thomas Hellerdb7b4432006-08-04 19:49:31 +00001024- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.
1025
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001026- Bug #1530448, ctypes build failure on Solaris 10 was fixed.
Thomas Heller17984892006-08-04 18:57:34 +00001027
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001028
Tim Peters4643c2f2006-08-10 22:45:34 +00001029C API
1030-----
1031
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001032- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1033
Tim Peters4643c2f2006-08-10 22:45:34 +00001034- Bug #1069160. Internal correctness changes were made to
1035 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1036 the documentation was changed to state that the return value
1037 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001040What's New in Python 2.5 beta 3?
1041================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001042
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001043*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001044
1045Core and builtins
1046-----------------
1047
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001048- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001049 returned a long (see PEP 353).
1050
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001051- Bug #1515471: string.replace() accepts character buffers again.
1052
Neal Norwitz07aadb12006-07-30 06:55:48 +00001053- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1054 This provides the proper warning for struct.pack().
1055 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1056
Neal Norwitz0d62a062006-07-30 06:53:31 +00001057- Patch #1531113: Fix augmented assignment with yield expressions.
1058 Also fix a SystemError when trying to assign to yield expressions.
1059
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001060- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1061 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1062 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1063 excessive filesystem operations during imports.
1064
Tim Petersbc24eee2006-07-27 01:14:53 +00001065- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1066 operations on signed longs that are formally undefined by C.
1067 Unfortunately, at least one compiler now cares about that, so complicated
1068 the code to make that compiler happy again.
1069
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001070- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1071
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001072- Patch #1232023: Stop including current directory in search
1073 path on Windows.
1074
Neal Norwitze1fdb322006-07-21 05:32:28 +00001075- Fix some potential crashes found with failmalloc.
1076
Neal Norwitze7563102006-07-17 01:00:16 +00001077- Fix warnings reported by Klocwork's static analysis tool.
1078
Neal Norwitz84be93b2006-07-16 01:50:38 +00001079- Bug #1512814, Fix incorrect lineno's when code within a function
1080 had more than 255 blank lines.
1081
Georg Brandl9dceedb2006-07-12 15:31:17 +00001082- Patch #1521179: Python now accepts the standard options ``--help`` and
1083 ``--version`` as well as ``/?`` on Windows.
1084
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001085- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001086 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001087 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001088
Tim Peters112aad32006-07-19 00:03:19 +00001089- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001090 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001091 new ``sys._current_frames()`` returns a dictionary with one entry,
1092 mapping the faux "thread id" 0 to the current frame.
1093
Ronald Oussoren3075e162006-07-25 20:28:55 +00001094- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001095
Ronald Oussoren3075e162006-07-25 20:28:55 +00001096
Neal Norwitza1f10902006-07-12 07:28:29 +00001097Library
1098-------
1099
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001100- Correction of patch #1455898: In the mbcs decoder, set final=False
1101 for stream decoder, but final=True for the decode function.
1102
Georg Brandl07fec3a2006-08-01 18:49:24 +00001103- os.urandom no longer masks unrelated exceptions like SystemExit or
1104 KeyboardInterrupt.
1105
Tim Peters4643c2f2006-08-10 22:45:34 +00001106- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001107 shutil.copytree on Windows
1108
Georg Brandle34ac7c2006-07-30 11:07:23 +00001109- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1110 refers to file descriptors, not file objects.
1111
Tim Peterscbdd3502006-09-05 01:47:53 +00001112- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001113 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001114 #1513611, and probably others.
1115
Georg Brandledd9b0d2006-07-29 09:33:26 +00001116- Bug #1441397: The compiler module now recognizes module and function
1117 docstrings correctly as it did in Python 2.4.
1118
Tim Peters6f681472006-07-27 23:44:37 +00001119- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1120 lost that tests are sorted by name before being run. This rarely
1121 matters for well-written tests, but can create baffling symptoms if
1122 side effects from one test to the next affect outcomes. ``DocTestFinder``
1123 has been changed to sort the list of tests it returns.
1124
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001125- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001126 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001127
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001128- Bug #978833: Really close underlying socket in _socketobject.close.
1129
Georg Brandldb232dc2006-08-20 13:15:43 +00001130- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1131 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001132
Georg Brandlcf0c1722006-07-26 07:23:32 +00001133- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1134 to recursive calls and call it with the failing package name.
1135
Martin v. Löwis0b483032006-07-25 09:53:12 +00001136- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1137
Georg Brandlc13c34c2006-07-24 14:09:56 +00001138- Patch #1515343: Fix printing of deprecated string exceptions with a
1139 value in the traceback module.
1140
Greg Ward48fae7a2006-07-23 16:05:51 +00001141- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1142
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001143- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1144
Brett Cannoncaebe222006-07-18 04:41:36 +00001145- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1146 argument tuple. For arguments where zero is illegal, the value is forced to
1147 the minimum value that is correct. This is to support an undocumented but
1148 common way people used to fill in inconsequential information in the time
1149 tuple pre-2.4.
1150
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001151- Patch #1220874: Update the binhex module for Mach-O.
1152
Barry Warsawb110bad2006-07-21 14:51:07 +00001153- The email package has improved RFC 2231 support, specifically for
1154 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1155 (name*0=<blah>) parameter continuations. This may change the types of
1156 values returned from email.message.Message.get_param() and friends.
1157 Specifically in some cases where non-encoded continuations were used,
1158 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1159 will just return the string (since non-encoded continuations don't have
1160 charset and language parts).
1161
1162 Also, whereas % values were decoded in all parameter continuations, they are
1163 now only decoded in encoded parameter parts.
1164
Ronald Oussoren3075e162006-07-25 20:28:55 +00001165- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1166
1167- Bug #1517996: IDLE now longer shows the default Tk menu when a
1168 path browser, class browser or debugger is the frontmost window on MacOS X
1169
Barry Warsaw00decd72006-07-27 23:43:15 +00001170- Patch #1520294: Support for getset and member descriptors in types.py,
1171 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1172 of an object against these built-in types and more importantly, for getting
1173 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001176Extension Modules
1177-----------------
1178
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001179- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1180 a socket operation on a socket with a timeout, the exception will be
1181 caught correctly. Previously, the exception was not caught.
1182
Thomas Heller1393d6a2006-07-28 21:43:20 +00001183- Patch #1529514: The _ctypes extension is now compiled on more
1184 openbsd target platforms.
1185
Tim Peters9cab5932006-07-28 00:30:00 +00001186- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1187 a memory leak, affecting pickles and deep copies.
1188
Tim Petersbc24eee2006-07-27 01:14:53 +00001189- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001190 Paul Eggert.
1191

1193
Thomas Hellerce049a02006-07-14 17:51:14 +00001194- Patch #1521817: Index range checking on ctypes arrays containing
1195 exactly one element enabled again. This allows iterating over these
1196 arrays, without the need to check the array size before.
1197
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001198- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001199 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001200 /dev/null in certain cases; this is now fixed.
1201
Thomas Heller47d7a062006-07-12 08:43:47 +00001202- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1203 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001204
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001205- Because of a misspelled preprocessor symbol, ctypes was always
1206 compiled without thread support; this is now fixed.
1207
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001208- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1209 methods now allow their database parameter to be None as the
1210 sleepycat API allows.
1211
Matt Flemingec926502006-07-28 11:27:27 +00001212- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1213 bluetooth API compared with Linux and FreeBSD.
1214
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001215Tests
1216-----
1217
1218- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1219 how long the test file should take to play. Now accepts taking 2.93 secs
1220 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1221
Georg Brandl4793aa32006-07-28 18:31:39 +00001222- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1223 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1224 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +00001225
Martin v. Löwis0907f4d2006-07-30 14:09:47 +00001226Build
1227-----
1228
1229- Bug #1439538: Drop usage of test -e in configure as it is not portable.
1230
Ronald Oussoren26cad082006-08-01 21:00:57 +00001231Mac
1232---
1233
1234- PythonLauncher now works correctly when the path to the script contains
1235 characters that are treated specially by the shell (such as quotes).
1236
1237- Bug #1527397: PythonLauncher now launches scripts with the working directory
1238 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001239 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001240 expect.

Georg Brandlad29e632006-06-21 17:45:17 +00001247
1248Core and builtins
1249-----------------
1250
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001251- Bug #1441486: The literal representation of -(sys.maxint - 1)
1252 again evaluates to a int object, not a long.
1253
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001254- Bug #1501934: The scope of global variables that are locally assigned
1255 using augmented assignment is now correctly determined.
1256
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001257- Bug #927248: Recursive method-wrapper objects can now safely
1258 be released.
1259
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001260- Bug #1417699: Reject locale-specific decimal point in float()
1261 and atof().
1262
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001263- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1264 omit a default "error" argument for NULL pointer. This allows
1265 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001266
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001267- Bug #1519018: 'as' is now validated properly in import statements.
1268
Neal Norwitz28746ab2006-07-09 22:14:42 +00001269- On 64 bit systems, int literals that use less than 64 bits are
1270 now ints rather than longs.
1271
Neal Norwitzed657552006-07-10 00:04:44 +00001272- Bug #1512814, Fix incorrect lineno's when code at module scope
1273 started after line 256.
1274
Tim Peters32a83612006-07-10 21:08:24 +00001275- New function ``sys._current_frames()`` returns a dict mapping thread
1276 id to topmost thread stack frame. This is for expert use, and is
1277 especially useful for debugging application deadlocks. The functionality
1278 was previously available in Fazal Majid's ``threadframe`` extension
1279 module, but it wasn't possible to do this in a wholly threadsafe way from
1280 an extension.
1281

1289
Tim Peters32a83612006-07-10 21:08:24 +00001290- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001291 environment variable to be set in order to the SDK environment
1292 for finding the compiler, include files, etc.

1295
Nick Coghlan2d792252006-07-06 13:47:18 +00001296- warnings.py now ignores ImportWarning by default
1297
Thomas Woutersadd19112006-07-05 11:03:49 +00001298- string.Template() now correctly handles tuple-values. Previously,
1299 multi-value tuples would raise an exception and single-value tuples would
1300 be treated as the value they contain, instead.
1301
Martin v. Löwisede77f52006-07-03 13:01:35 +00001302- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1303 even if some data are received.
1304
Martin v. Löwis45482392006-07-03 12:28:58 +00001305- Bug #1267547: Put proper recursive setup.py call into the
1306 spec file generated by bdist_rpm.
1307
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001308- Bug #1514693: Update turtle's heading when switching between
1309 degrees and radians.
1310
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001311- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001312 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001313
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001314- Bug #1514703: Only setup canvas window in turtle when the canvas
1315 is created.
1316
Martin v. Löwis7596e832006-07-01 15:33:37 +00001317- Bug #1513223: .close() of a _socketobj now releases the underlying

1321 attribute values.
1322
1323- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1324 sgmllib ('[' and ']' were not accepted).
1325
Georg Brandl1be63af2006-06-28 20:23:25 +00001326- Fix a bug in the turtle module's end_fill function.
1327
Brett Cannon53ab5b72006-06-22 16:49:14 +00001328- Bug #1510580: The 'warnings' module improperly required that a Warning
1329 category be either a types.ClassType and a subclass of Warning. The proper
1330 check is just that it is a subclass with Warning as the documentation states.
1331
Georg Brandlad29e632006-06-21 17:45:17 +00001332- The compiler module now correctly compiles the new try-except-finally
1333 statement (bug #1509132).
1334
Neal Norwitz60373cd2006-06-22 06:30:50 +00001335- The wsgiref package is now installed properly on Unix.
1336
Vinay Sajip28e57612006-07-01 10:45:20 +00001337- A bug was fixed in logging.config.fileConfig() which caused a crash on
1338 shutdown when fileConfig() was called multiple times.
1339
Gerhard Häring762fbd32006-07-02 17:48:30 +00001340- The sqlite3 module did cut off data from the SQLite database at the first
1341 null character before sending it to a custom converter. This has been fixed
1342 now.
1343
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001344Extension Modules
1345-----------------
1346
Tim Peters112aad32006-07-19 00:03:19 +00001347- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1348 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1349 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001350
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001351- Assigning None to pointer type fields in ctypes structures possible
1352 overwrote the wrong fields, this is fixed now.
1353
1354- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1355 on non-Windows platforms.
1356
1357- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1358 integer or long, without range checking.
1359
1360- Patch #1517790: It is now possible to use custom objects in the ctypes
1361 foreign function argtypes sequence as long as they provide a from_param
1362 method, no longer is it required that the object is a ctypes type.
1363
1364- The '_ctypes' extension module now works when Python is configured
1365 with the --without-threads option.
1366
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001367- Bug #1513646: os.access on Windows now correctly determines write
1368 access, again.
1369
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001370- Bug #1512695: cPickle.loads could crash if it was interrupted with
1371 a KeyboardInterrupt.
1372
Neal Norwitza12aa882006-07-06 06:45:08 +00001373- Bug #1296433: parsing XML with a non-default encoding and
1374 a CharacterDataHandler could crash the interpreter in pyexpat.
1375
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001376- Patch #1516912: improve Modules support for OpenVMS.
1377
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001378Build
1379-----
1380
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001381- Automate Windows build process for the Win64 SSL module.
1382
Tim Peters32a83612006-07-10 21:08:24 +00001383- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001384 Previously, the slight difference could cause compilation errors of the
1385 'zlib' module on systems with more than one version of zlib.
1386
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001387- The MSI compileall step was fixed to also support a TARGETDIR
1388 with spaces in it.
1389
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001390- Bug #1517388: sqlite3.dll is now installed on Windows independent

1398
1399- Call os.waitpid() at the end of tests that spawn child processes in order
1400 to minimize resources (zombies).
1401
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001402Documentation
1403-------------
1404
Nick Coghlan2d792252006-07-06 13:47:18 +00001405- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1406 documentation for the warnings module.
1407
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001408- Patch #1509163: MS Toolkit Compiler no longer available.
1409

1419-----------------
1420
Georg Brandla56b9152006-06-19 06:35:54 +00001421- Patch #1507676: Error messages returned by invalid abstract object operations
1422 (such as iterating over an integer) have been improved and now include the
1423 type of the offending object to help with debugging.
1424
Brett Cannonea3912b2006-06-13 21:46:41 +00001425- Bug #992017: A classic class that defined a __coerce__() method that returned
1426 its arguments swapped would infinitely recurse and segfault the interpreter.
1427
Neal Norwitz909eb122006-06-12 02:13:21 +00001428- Fix the socket tests so they can be run concurrently.
1429
Neal Norwitzb9845e72006-06-12 02:11:18 +00001430- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001431 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001432
Brett Cannon22565aa2006-06-09 22:31:23 +00001433- Bug #532646: object.__call__() will continue looking for the __call__
1434 attribute on objects until one without one is found. This leads to recursion
1435 when you take a class and set its __call__ attribute to an instance of the
1436 class. Originally fixed for classic classes, but this fix is for new-style.
1437 Removes the infinite_rec_3 crasher.
1438
Georg Brandl24250812006-06-09 18:45:48 +00001439- The string and unicode methods startswith() and endswith() now accept
1440 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1441
Brett Cannonde3b0522006-06-08 17:00:45 +00001442- Buffer objects, at the C level, never used the char buffer
1443 implementation even when the char buffer for the wrapped object was
1444 explicitly requested (originally returned the read or write buffer).
1445 Now a TypeError is raised if the char buffer is not present but is
1446 requested.
1447
Georg Brandlddbaa662006-06-04 21:56:52 +00001448- Patch #1346214: Statements like "if 0: suite" are now again optimized
1449 away like they were in Python 2.4.
1450
Georg Brandlb7c8f542006-05-27 12:30:25 +00001451- Builtin exceptions are now full-blown new-style classes instead of
1452 instances pretending to be classes, which speeds up exception handling
1453 by about 80% in comparison to 2.5a2.
1454
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001455- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1456 Unicode 4.1.
1457
Georg Brandlf4ef1162006-05-26 18:03:31 +00001458- Patch #921466: sys.path_importer_cache is now used to cache valid and
1459 invalid file paths for the built-in import machinery which leads to
1460 fewer open calls on startup.
1461
Tim Peters696cf432006-05-24 21:10:40 +00001462- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1463 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1464 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1465 the number of input digits (it was and remains linear-time for bases
1466 2, 4, 8, 16 and 32).
1467
Tim Petersb713ec22006-05-23 18:45:30 +00001468- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1469 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1470 an integer close to ``sys.maxint``. This was repaired by patch
1471 #1335972, which also gives a nice speedup.
1472
Richard Jonescebbefc2006-05-23 18:28:17 +00001473- Patch #1337051: reduced size of frame objects.
1474
1475- PyErr_NewException now accepts a tuple of base classes as its
1476 "base" parameter.
1477
Richard Jones7c88dcc2006-05-23 10:37:38 +00001478- Patch #876206: function call speedup by retaining allocated frame
1479 objects.
1480
Georg Brandl7b90e162006-05-18 07:01:27 +00001481- Bug #1462152: file() now checks more thoroughly for invalid mode
1482 strings and removes a possible "U" before passing the mode to the
1483 C library function.
1484
Neal Norwitz1004a532006-05-15 07:17:23 +00001485- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1486
Neal Norwitz373f0a72006-05-15 07:04:36 +00001487- Bug #1487966: Fix SystemError with conditional expression in assignment
1488
Martin v. Löwis879768d2006-05-11 13:28:43 +00001489- WindowsError now has two error code attributes: errno, which carries
1490 the error values from errno.h, and winerror, which carries the error
1491 values from winerror.h. Previous versions put the winerror.h values
1492 (from GetLastError()) into the errno attribute.
1493
Martin v. Löwis77736712006-05-04 05:51:03 +00001494- Patch #1475845: Raise IndentationError for unexpected indent.
1495
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001496- Patch #1479181: split open() and file() from being aliases for each other.
1497
Tim Peters44bd9862006-06-01 13:49:23 +00001498- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1499 methods were always silently ignored by dictionaries when comparing keys.
1500 They are now passed through (except when using the C API function
1501 ``PyDict_GetItem()``, whose semantics did not change).
1502
1503- Bug #1456209: In some obscure cases it was possible for a class with a
1504 custom ``__eq__()`` method to confuse dict internals when class instances
1505 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1506 No, you don't have any code that did this ;-)

1509-----------------
1510
Trent Mick960a3f82006-06-28 20:30:41 +00001511- Bug #1295808: expat symbols should be namespaced in pyexpat
1512
1513- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1514
Brett Cannon6ee7d012006-06-08 16:23:04 +00001515- Change binascii.hexlify to accept a read-only buffer instead of only a char
1516 buffer and actually follow its documentation.
1517
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001518- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1519
Nick Coghlanc649ec52006-05-29 12:43:05 +00001520- Patch #1478788 (modified version): The functional extension module has
1521 been renamed to _functools and a functools Python wrapper module added.
1522 This provides a home for additional function related utilities that are
1523 not specifically about functional programming. See PEP 309.
1524
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001525- Patch #1493701: performance enhancements for struct module.
1526
Georg Brandl378d5922006-05-17 14:26:50 +00001527- Patch #1490224: time.altzone is now set correctly on Cygwin.
1528
Georg Brandl8d3342b2006-05-16 07:38:27 +00001529- Patch #1435422: zlib's compress and decompress objects now have a
1530 copy() method.
1531
Andrew MacIntyre92913322006-06-13 15:04:24 +00001532- Patch #1454481: thread stack size is now tunable at runtime for thread
1533 enabled builds on Windows and systems with Posix threads support.
1534
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001535- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1536 (up to the system limit of 32K characters).
1537
1538- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1539 As a result, these functions now raise WindowsError instead of OSError.
1540
Tim Peters7a822da2006-05-25 21:50:17 +00001541- ``time.clock()`` on Win64 should use the high-performance Windows
1542 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1543 Windows platforms).
1544
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001545- Calling Tk_Init twice is refused if the first call failed as that
1546 may deadlock.
1547
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001548- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1549 accept it without potentially using an uninitialized pointer.
1550
1551- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1552 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1553 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001554
Gregory P. Smith372b5832006-06-05 18:48:21 +00001555- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001556 [pybsddb project SF patch number 1466734]
1557
Gregory P. Smith372b5832006-06-05 18:48:21 +00001558- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1559 parameter is supplied. [SF pybsddb bug #1477863]
1560
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001561- bsddb: the __len__ method of a DB object has been fixed to return correct
1562 results. It could previously incorrectly return 0 in some cases.
1563 Fixes SF bug 1493322 (pybsddb bug 1184012).
1564
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001565- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1566 aborts the db transaction safely when a modifier callback fails.
1567 Fixes SF python patch/bug #1408584.
1568
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001569- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001570 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001571 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1572 database calls that would previously deadlock. [SF python bug #775414]
1573
Vinay Sajip28e57612006-07-01 10:45:20 +00001574- Patch #1446489: add support for the ZIP64 extensions to zipfile.

1589
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001590- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.

1593 classes.
1594
Georg Brandl83cc0d02006-06-14 08:50:03 +00001595- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1596 mime.types file for determining MIME types.
1597
Georg Brandl2605ca82006-06-14 06:08:31 +00001598- Bug #1339007: Shelf objects now don't raise an exception in their
1599 __del__ method when initialization failed.
1600
Martin v. Löwisd8251432006-06-14 05:21:04 +00001601- Patch #1455898: The MBCS codec now supports the incremental mode for
1602 double-byte encodings.
1603
Tim Peters43898b42006-06-14 04:09:25 +00001604- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1605 guarantee that adjacent triples in the return list always describe
1606 non-adjacent blocks. Previously, a pair of matching blocks could end
1607 up being described by multiple adjacent triples that formed a partition
1608 of the matching pair.
1609
Greg Ward0e0c9f42006-06-11 16:24:11 +00001610- Bug #1498146: fix optparse to handle Unicode strings in option help,
1611 description, and epilog.
1612
Greg Wardd1c797e2006-06-11 14:42:41 +00001613- Bug #1366250: minor optparse documentation error.
1614
Greg Ward7f547402006-06-11 00:40:49 +00001615- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1616 clarify docs.
1617
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001618- The wsgiref package has been added to the standard library.
1619
Nick Coghlan676725d2006-06-08 13:54:49 +00001620- The functions update_wrapper() and wraps() have been added to the functools
1621 module. These make it easier to copy relevant metadata from the original
1622 function when writing wrapper functions.
1623
Tim Petersd6a9eef2006-06-05 01:48:21 +00001624- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1625 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001626
Martin v. Löwis3f767792006-06-04 19:36:28 +00001627- Patch #1359618: Speed up charmap encoder by using a trie structure
1628 for lookup.
1629
Tim Petersd609b1a2006-06-02 23:22:51 +00001630- The functions in the ``pprint`` module now sort dictionaries by key
1631 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1632 if and only if its display required more than one line, although that
1633 wasn't documented. The new behavior increases predictability; e.g.,
1634 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1635
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001636- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1637 (thanks for J. J. Lee).
1638
Georg Brandl2b330372006-05-28 20:23:12 +00001639- Patch #1496206: improve urllib2 handling of passwords with respect to
1640 default HTTP and HTTPS ports.
1641
George Yoshidaf3c65de2006-05-28 16:39:09 +00001642- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1643
Bob Ippolito7298f272006-05-23 18:43:47 +00001644- Patch #1281707: speed up gzip.readline.
1645
Georg Brandlb89316f2006-05-17 15:51:16 +00001646- Patch #1180296: Two new functions were added to the locale module:
1647 format_string() to get the effect of "format % items" but locale-aware,
1648 and currency() to format a monetary number with currency sign.
1649
Georg Brandle3a25832006-05-17 14:56:04 +00001650- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1651 and several features added, such as speed and geometry control.
1652
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001653- Patch #1488881: add support for external file objects in bz2 compressed
1654 tarfiles.
1655
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001656- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1657 stdout arguments, making it possible to redirect input and output
1658 for remote debugging.
1659
1660- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1661 a couple of issues, notably handling of long file names using the
1662 GNU LONGNAME extension.
1663
1664- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1665 new flag when ``name`` is already the name of an option flag.
1666
1667- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1668 package.
1669
1670- Patch #1472854: make the rlcompleter.Completer class usable on non-
1671 UNIX platforms.
1672
1673- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1674
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001675- Bug #1472827: correctly escape newlines and tabs in attribute values in
1676 the saxutils.XMLGenerator class.

1712-----------------
1713
Thomas Heller1b046642006-04-18 18:51:06 +00001714- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1715 by converting these apis from macros into exported functions again:
1716
1717 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1718 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1719 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1720 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1721 PyRun_String Py_CompileString
1722
Martin v. Löwis45294a92006-04-18 06:24:08 +00001723- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1724
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001725- All uses of PyStructSequence_InitType have been changed to initialize
1726 the type objects only once, even if the interpreter is initialized
1727 multiple times.
1728
Neal Norwitz61546162006-04-14 05:20:28 +00001729- Bug #1454485, array.array('u') could crash the interpreter. This was
1730 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1731 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1732
1733- Py_UNICODE is unsigned. It was always documented as unsigned, but
1734 due to a bug had a signed value in previous versions.
1735
Tim Peters3a5e8b12006-04-11 01:44:07 +00001736- Patch #837242: ``id()`` of any Python object always gives a positive
1737 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1738 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001739 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001740 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001741
Tim Peters3a5e8b12006-04-11 01:44:07 +00001742 def __hash__(self):
1743 return id(self) # WRONG
1744
1745 because a hash result must be a (short) Python int but it was always
1746 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001747 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001748 was always usable as a hash value before this patch. That's no longer
1749 necessarily so.
1750
1751- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001752 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001753 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001754 #1454844)
1755
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001756- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1757 involving generators that have paused outside of any ``try`` or ``with``
1758 blocks. (In 2.5a1, a paused generator that was part of a reference
1759 cycle could not be garbage collected, regardless of whether it was
1760 paused in a ``try`` or ``with`` block.)

1763-----------------
1764
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001765- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1766 is a macro.
1767
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001768- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1769 fails with an error condition.

Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001771- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1772
1773- Bug #1117761: bsddb.*open() no longer raises an exception when using
1774 the cachesize parameter.
1775
1776- Bug #1149413: bsddb.*open() no longer raises an exception when using
1777 a temporary db (file=None) with the 'n' flag to truncate on open.
1778
1779- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1780 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001781
Armin Rigoa9017c32006-04-19 11:50:27 +00001782- Patch #1062014: AF_UNIX sockets under Linux have a special
1783 abstract namespace that is now fully supported.

1787
Peter Astrand7d1d4362006-07-14 14:04:45 +00001788- Bug #1223937: subprocess.CalledProcessError reports the exit status
1789 of the process using the returncode attribute, instead of
1790 abusing errno.
1791
Tim Peters711bf302006-04-25 03:31:36 +00001792- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1793 a doctest to be skipped (the code is not run, and the expected output
1794 or exception is ignored).
1795
Nick Coghlanda2268f2006-04-24 04:37:15 +00001796- Fixed contextlib.nested to cope with exceptions being raised and
1797 caught inside exit handlers.
1798
Greg Wardab05edc2006-04-23 03:47:58 +00001799- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1800 hex, octal, or binary; add ``append_const`` action; keep going if
1801 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1802 added ``epilog`` for better help generation).
1803
Tim Peters21fbd572006-04-21 21:18:10 +00001804- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1805 called from a thread spawned as a side effect of importing a module.
1806
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001807- The pydoc module now supports documenting packages contained in
1808 .zip or .egg files.
1809
1810- The pkgutil module now has several new utility functions, such
1811 as ``walk_packages()`` to support working with packages that are either
1812 in the filesystem or zip files.
1813
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001814- The mailbox module can now modify and delete messages from
1815 mailboxes, in addition to simply reading them. Thanks to Gregory
1816 K. Johnson for writing the code, and to the 2005 Google Summer of
1817 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001818
Tim Petersc7605f22006-04-17 21:12:33 +00001819- The ``__del__`` method of class ``local`` in module ``_threading_local``
1820 returned before accomplishing any of its intended cleanup.

Anthony Baxtere29002c2006-04-12 12:07:31 +00001828- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1829 Windows. Bug #1469163.
1830
Phillip J. Eby47032112006-04-11 01:07:43 +00001831- The warnings, linecache, inspect, traceback, site, and doctest modules
1832 were updated to work correctly with modules imported from zipfiles or
1833 via other PEP 302 __loader__ objects.

1841
Skip Montanaro262fb922006-04-21 02:31:07 +00001842- The pstats.Stats class accepts an optional stream keyword argument to
1843 direct output to an alternate file-like object.
1844
Anthony Baxter51bcb682006-04-05 14:51:42 +00001845Build
1846-----
1847
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001848- The Makefile now has a reindent target, which runs reindent.py on
1849 the library.
1850
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001851- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001854
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001855- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1856 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001857 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001858 CXX from --with-cxx-main, see description in README.
1859
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001860- Patch #1429775: Link extension modules with the shared libpython.
1861
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001862- Fixed a libffi build problem on MIPS systems.
1863
Tim Peters8931ff12006-05-13 23:28:20 +00001864- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1865 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1866 and "%zu" for unsigned integers of type ``size_t``.
1867
Anthony Baxter51bcb682006-04-05 14:51:42 +00001868Tests
1869-----
1870
Nick Coghlanda2268f2006-04-24 04:37:15 +00001871- test_contextlib now checks contextlib.nested can cope with exceptions
1872 being raised and caught inside exit handlers.
1873
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001874- test_cmd_line now checks operation of the -m and -c command switches
1875
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001876- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1877 it separately and by hand. It also wasn't cleaning up its changes to
1878 the current Decimal context.
1879
Thomas Woutersabd08882006-04-26 15:53:30 +00001880- regrtest.py now has a -M option to run tests that test the new limits of
1881 containers, on 64-bit architectures. Running these tests is only sensible
1882 on 64-bit machines with more than two gigabytes of memory. The argument
1883 passed is the maximum amount of memory for the tests to use.

1892-------------
1893
Tim Petersb06d28c2006-05-12 01:57:59 +00001894- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1895
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001896- PEP 343: Added Context Types section to the library reference
1897 and attempted to bring other PEP 343 related documentation into
1898 line with the implementation and/or python-dev discussions.
1899
Tim Peters8dc73d22006-04-24 02:03:16 +00001900- Bug #1337990: clarified that ``doctest`` does not support examples
1901 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001909Core and builtins
1910-----------------
1911
Nick Coghlan43832302006-04-23 17:04:07 +00001912- PEP 338: -m command line switch now delegates to runpy.run_module
1913 allowing it to support modules in packages and zipfiles
1914
Martin v. Löwisc661b882006-04-20 04:54:23 +00001915- On Windows, .DLL is not an accepted file name extension for
1916 extension modules anymore; extensions are only found if they
1917 end in .PYD.
1918
Martin v. Löwisea62d252006-04-03 10:56:49 +00001919- Bug #1421664: sys.stderr.encoding is now set to the same value as
1920 sys.stdout.encoding.
1921
Neal Norwitz92e212f2006-04-03 04:48:37 +00001922- __import__ accepts keyword arguments.
1923
Georg Brandlccadf842006-03-31 18:54:53 +00001924- Patch #1460496: round() now accepts keyword arguments.
1925
Anthony Baxter262c00a2006-03-30 10:53:17 +00001926- Fixed bug #1459029 - unicode reprs were double-escaped.
1927
Hye-Shik Changd478f342006-03-23 12:32:36 +00001928- Patch #1396919: The system scope threads are reenabled on FreeBSD
1929 5.4 and later versions.
1930
Neal Norwitze98ccf62006-03-23 05:39:47 +00001931- Bug #1115379: Compiling a Unicode string with an encoding declaration
1932 now gives a SyntaxError.
1933
Georg Brandlabd1ff82006-03-18 07:59:59 +00001934- Previously, Python code had no easy way to access the contents of a
1935 cell object. Now, a ``cell_contents`` attribute has been added
1936 (closes patch #1170323).
1937
Tim Peterscf79aac2006-03-16 01:14:46 +00001938- Patch #1123430: Python's small-object allocator now returns an arena to
1939 the system ``free()`` when all memory within an arena becomes unused
1940 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1941 freed. Some applications will see a drop in virtual memory size now,
1942 especially long-running applications that, from time to time, temporarily
1943 use a large number of small objects. Note that when Python returns an
1944 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001945 platform C library will in turn return that memory to the operating system.
1946 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001947 appears to be effective at least on Microsoft C and gcc-based systems.
1948 Thanks to Evan Jones for hard work and patience.
1949
Georg Brandl533ff6f2006-03-08 18:09:27 +00001950- Patch #1434038: property() now uses the getter's docstring if there is
1951 no "doc" argument given. This makes it possible to legitimately use
1952 property() as a decorator to produce a read-only property.
1953
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001954- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1955 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1956 of requiring an int or long in slicing and a few other contexts, enabling
1957 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1958
Neal Norwitz995acdf2006-03-07 05:01:00 +00001959- Fixed various bugs reported by Coverity's Prevent tool.
1960
Brett Cannonbf364092006-03-01 04:25:17 +00001961- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1962 new exception base class, BaseException, which has a new message attribute.
1963 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1964 Raising a string exception now raises a DeprecationWarning.
1965
Thomas Woutersfb609f42006-02-28 16:37:25 +00001966- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1967 explicitly relative, using 'from .module import name' to mean 'from the same
1968 package as this module is in. Imports without dots still default to the
1969 old relative-then-absolute, unless 'from __future__ import
1970 absolute_import' is used.
1971
Brett Cannona7446e32006-02-27 23:39:10 +00001972- Properly check if 'warnings' raises an exception (usually when a filter set
1973 to "error" is triggered) when raising a warning for raising string
1974 exceptions.
1975
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001976- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001977 The name was removed from Include/code.h.
1978
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001979- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001980
Guido van Rossum1968ad32006-02-25 22:38:04 +00001981- Patch 1433928:
1982 - The copy module now "copies" function objects (as atomic objects).
1983 - dict.__getitem__ now looks for a __missing__ hook before raising
1984 KeyError.
1985
Tim Peters84ef21c2006-02-28 20:39:06 +00001986- PEP 343: with statement implemented. Needs ``from __future__ import
1987 with_statement``. Use of 'with' as a variable will generate a warning.
1988 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001989 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001990 The following objects have __context__ methods:
1991 - The built-in file type.
1992 - The thread.LockType type.
1993 - The following types defined by the threading module:
1994 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1995 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001996
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001997- Fix the encodings package codec search function to only search
1998 inside its own package. Fixes problem reported in patch #1433198.
1999
2000 Note: Codec packages should implement and register their own
2001 codec search function. PEP 100 has the details.
2002
Tim Peters9ea89d22006-06-04 03:26:02 +00002003- PEP 353: Using ``Py_ssize_t`` as the index type.
2004
2005- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2006 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2007 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2008 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2009 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002010
Neal Norwitzfc76d632006-01-10 06:03:13 +00002011- Patch #1400181, fix unicode string formatting to not use the locale.
2012 This is how string objects work. u'%f' could use , instead of .
2013 for the decimal point. Now both strings and unicode always use periods.
2014
Neal Norwitz671b9e32006-01-09 07:07:12 +00002015- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2016 configure would break checking curses.h.
2017
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002018- Bug #959576: The pwd module is now builtin. This allows Python to be
2019 built on UNIX platforms without $HOME set.
2020
Neal Norwitzc10978f2005-12-19 06:07:16 +00002021- Bug #1072182, fix some potential problems if characters are signed.
2022
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002023- Bug #889500, fix line number on SyntaxWarning for global declarations.
2024
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002025- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2026
Neal Norwitze7214a12005-12-18 05:03:17 +00002027- Support for converting hex strings to floats no longer works.
2028 This was not portable. float('0x3') now raises a ValueError.
2029
Barry Warsaw2a38a862005-12-18 01:27:35 +00002030- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002031 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002032 is now displayed in interactive prompt banner.
2033
Georg Brandlfa166682005-12-17 21:45:17 +00002034- Implementation of PEP 341 - Unification of try/except and try/finally.
2035 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002036 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002037
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002038- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2039 now encodes backslash correctly.
2040
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002041- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2042
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002043- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002044 and long longs.
2045
Neal Norwitz67715f02005-11-09 06:59:35 +00002046- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002047 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002048 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002049
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002050- Replaced most Unicode charmap codecs with new ones using the
2051 new Unicode translate string feature in the builtin charmap
2052 codec; the codecs were created from the mapping tables available
2053 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2054 encodings now include a mapping for the Apple logo)

Tim Peterse3547fd2005-12-16 23:13:57 +00002056- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002057
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002058- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002059
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002060- A new AST parser implementation was completed. The abstract
2061 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002062 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002063
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002064- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002065 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2066
Neal Norwitz708e51a2005-10-03 04:48:15 +00002067- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2068
Neal Norwitz11bd1192005-10-03 00:54:56 +00002069- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2070 Provide a warning when a directory is passed on the command line.
2071
Neal Norwitz40d37812005-10-02 01:48:49 +00002072- Fix segfault with invalid coding.
2073
2074- SF bug #772896: unknown encoding results in MemoryError.
2075
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002076- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002077 supported a __len__() method which evaluated to False when the iterator
2078 was empty.
2079
Guido van Rossum630db602005-09-20 18:49:54 +00002080- On 64-bit platforms, when __len__() returns a value that cannot be
2081 represented as a C int, raise OverflowError.
2082
Skip Montanarof8948ca2005-09-19 03:54:46 +00002083- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002084 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002085
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002086- SF bug #893549: parsing keyword arguments was broken with a few format
2087 codes.
2088
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002089- Changes donated by Elemental Security to make it work on AIX 5.3
2090 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2091 bug #105470: test_pwd fails on 64bit system (Opteron).
2092
Guido van Rossum539c6622005-09-14 17:49:54 +00002093- Changes donated by Elemental Security to make it work on HP-UX 11 on
2094 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2095
Georg Brandl4550b8d2005-08-26 06:43:52 +00002096- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002097 (fixes bug #1119418).
2098
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002099- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2100
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002101- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2102 exceptions that cause a function to exit.
2103
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002104- The implementation of set() and frozenset() was revised to use its
2105 own internal data structure. Memory consumption is reduced by 1/3
2106 and there are modest speed-ups as well. The API is unchanged.
2107
Tim Petersde7990b2005-07-17 23:45:23 +00002108- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2109
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002110- SF bug #1229429: PyObject_CallMethod failed to decrement some
2111 reference counts in some error exit cases.
2112
Tim Petersecc6e6a2005-07-10 22:30:55 +00002113- SF bug #1185883: Python's small-object memory allocator took over
2114 a block managed by the platform C library whenever a realloc specified
2115 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002116 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002117 portable way to copy data from the C-managed block into Python's
2118 small-object space without risking a memory fault. Python's small-object
2119 realloc now leaves such blocks under the control of the platform C
2120 realloc.
2121
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002122- SF bug #1232517: An overflow error was not detected properly when
2123 attempting to convert a large float to an int in os.utime().
2124
Raymond Hettinger3296e692005-06-29 23:29:56 +00002125- SF bug #1224347: hex longs now print with lowercase letters just
2126 like their int counterparts.
2127
Michael W. Hudson188d4362005-06-20 16:52:57 +00002128- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2129 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2130 interpreter states; back out that fix and do a better job (see
2131 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2132 for a longer write-up of the problem).
2133
Michael W. Hudsondf888462005-06-03 14:41:55 +00002134- SF patch #1180995: marshal now uses a binary format by default when
2135 serializing floats.
2136
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002137- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2138 the routines that promise to produce IEEE 754 binary representations
2139 of floats now simply copy bytes around.
2140
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002141- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2142 278.
2143
Brett Cannonc3647ac2005-04-26 03:45:26 +00002144- patch #1109424: int, long, float, complex, and unicode now check for the
2145 proper magic slot for type conversions when subclassed. Previously the
2146 magic slot was ignored during conversion. Semantics now match the way
2147 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002148 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002149 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002150 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002151
Barry Warsawc8d907c2005-04-19 23:43:40 +00002152- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2153 NULL, now raise an AttributeError when attempting to set or delete the
2154 attribute. Previously a TypeError was raised, but this was inconsistent
2155 with the equivalent pure-Python implementation.
2156
Michael W. Hudson774479c2005-04-18 08:46:17 +00002157- It is now safe to call PyGILState_Release() before
2158 PyEval_InitThreads() (note that if there is reason to believe there
2159 are multiple threads around you still must call PyEval_InitThreads()
2160 before using the Python API; this fix is for extension modules that
2161 have no way of knowing if Python is multi-threaded yet).
2162
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002163- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2164 disabled caused a crash.
2165
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002166- Bug #1165306: instancemethod_new allowed the creation of a method
2167 with im_class == im_self == NULL, which caused a crash when called.
2168
Tim Petersecc6e6a2005-07-10 22:30:55 +00002169- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002170 fixes the crash seen in bug #1165761
2171
Raymond Hettinger96229b12005-03-11 06:49:40 +00002172- Added two new builtins, any() and all().
2173
Brett Cannon409d8f22005-03-05 06:47:57 +00002174- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002175 (e.g., ``class C(): pass`` is no longer a syntax error).
2176 Patch #1176012 added support to the 'parser' module and 'compiler' package
2177 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002178
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002179- Patch #1115086: Support PY_LONGLONG in structmember.
2180
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002181- Bug #1155938: new style classes did not check that __init__() was
2182 returning None.
2183
Tim Petersecc6e6a2005-07-10 22:30:55 +00002184- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002185 ('\') with a specific error message.
2186
Martin v. Löwisff232d72005-03-03 09:24:38 +00002187- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2188
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002189- Bug #1124295: the __name__ attribute of file objects was
2190 inadvertently made inaccessible in restricted mode.
2191
Tim Petersecc6e6a2005-07-10 22:30:55 +00002192- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002193 an ferror() call.
2194
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002195- min() and max() now support key= arguments with the same meaning as in
2196 list.sort().
2197
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002198- The peephole optimizer now performs simple constant folding in expressions:
2199 (2+3) --> (5).
2200
Raymond Hettingera422c342005-01-11 03:03:27 +00002201- set and frozenset objects can now be marshalled. SF #1098985.
2202
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002203- Bug #1077106: Poor argument checking could cause memory corruption
2204 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002205
Jeremy Hyltonab630502005-02-04 18:44:06 +00002206- The parser did not complain about future statements in illegal
2207 positions. It once again reports a syntax error if a future
2208 statement occurs after anything other than a doc string.
2209
Neil Schemenauercf52c072005-08-12 17:34:58 +00002210- Change the %s format specifier for str objects so that it returns a
2211 unicode instance if the argument is not an instance of basestring and
2212 calling __str__ on the argument returns a unicode instance.
2213
Tim Petersf4e69282006-02-27 17:15:31 +00002214- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2215 current thread state when the auto-GIL-state machinery knows about
2216 it (since the thread state is being deleted, continuing to remember it
2217 can't help, but can hurt if another thread happens to get created with
2218 the same thread id).
2219
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002220Extension Modules
2221-----------------
2222
Georg Brandl43f08a82006-03-31 18:01:16 +00002223- Patch #1380952: fix SSL objects timing out on consecutive read()s

Tim Petersc9d78aa2006-03-26 23:27:58 +00002235 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00002236 util, whatsound, whrandom, zmod
2237
2238- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2239
2240- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002241 is deprecated. The undocumented re.engine variable no longer exists.
2242
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002243- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2244 SS2 (single-shift 2) escape sequences correctly.
2245
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002246- The unicodedata module was updated to the 4.1 version of the Unicode
2247 database. The 3.2 version is still available as unicodedata.db_3_2_0
2248 for applications that require this specific version (such as IDNA).
2249
Neal Norwitzb62c4332006-03-04 18:35:47 +00002250- The timing module is no longer built by default. It was deprecated
2251 in PEP 4 in Python 2.0 or earlier.
2252
Guido van Rossum1968ad32006-02-25 22:38:04 +00002253- Patch 1433928: Added a new type, defaultdict, to the collections module.
2254 This uses the new __missing__ hook behavior added to dict (see above).
2255
Georg Brandldbd83392006-02-20 09:42:33 +00002256- Bug #854823: socketmodule now builds on Sun platforms even when
2257 INET_ADDRSTRLEN is not defined.
2258
Georg Brandlf4f44152006-02-18 22:29:33 +00002259- Patch #1393157: os.startfile() now has an optional argument to specify
2260 a "command verb" to invoke on the file.
2261
Neal Norwitz082b2df2006-02-07 07:04:46 +00002262- Bug #876637, prevent stack corruption when socket descriptor
2263 is larger than FD_SETSIZE.
2264
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00002265- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
2266 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
2267 mmap.mmap(0, size) should not be used on Windows for anonymous memory.

2270 than the system default domain.
2271
Martin v. Löwis14694662006-02-03 12:54:16 +00002272- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2273 are reported, the limit on path name lengths is removed, and stat reports
2274 WindowsError now (instead of OSError).
2275
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002276- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

2351 the request code argument, which results in more C-like behaviour
2352 for large or negative values.
2353
Tim Petersecc6e6a2005-07-10 22:30:55 +00002354- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

2395 args tuple returned by __reduce__().
2396
Raymond Hettingerb2594052004-12-05 09:25:51 +00002397- itertools.islice() now accepts None for the start and step arguments.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002410- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2411 been renamed to have only a single underscore prefix. This was done to
2412 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002413
Nick Coghlan43832302006-04-23 17:04:07 +00002414- PEP 338: new module runpy defines a run_module function to support
2415 executing modules which provide access to source code or a code object
2416 via the PEP 302 import mechanisms.
2417
Anthony Baxter93f5b932006-04-03 08:05:07 +00002418- The email module's parsedate_tz function now sets the daylight savings
2419 flag to -1 (unknown) since it can't tell from the date whether it should

2426 in attribute values.
2427
Anthony Baxterc51ee692006-04-01 00:57:31 +00002428- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002429 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002430 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002431 module will not be built.
2432
Tim Petersc17976e2006-04-01 00:26:53 +00002433- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2434 aren't officially supported here, and trying to use them will probably
2435 raise an exception some day. But dicts have been allowed, and "mostly
2436 worked", so support for them won't go away without warning.
2437
Georg Brandl338ef7d2006-03-31 18:42:16 +00002438- Bug #1445068: getpass.getpass() can now be given an explicit stream
2439 argument to specify where to write the prompt.
2440
Georg Brandl22ec80b2006-03-31 18:25:44 +00002441- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2448
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002449- Queue.Queue objects now support .task_done() and .join() methods
2450 to make it easier to monitor when daemon threads have completed
2451 processing all enqueued tasks. Patch #1455676.
2452

2456
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002457- email 4.0 package now integrated. This is largely the same as the email 3.0
2458 package that was included in Python 2.3, except that PEP 8 module names are
2459 now used (e.g. mail.message instead of email.Message). The MIME classes
2460 have been moved to a subpackage (e.g. email.mime.text instead of
2461 email.MIMEText). The old names are still supported for now. Several
2462 deprecated Message methods have been removed and lots of bugs have been
2463 fixed. More details can be found in the email package documentation.
2464
Walter Dörwald40108c92006-03-27 08:15:44 +00002465- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2466 (a subclass of tuple) that provides incremental decoders and encoders
2467 (a way to use stateful codecs without the stream API). Python functions
2468 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2469 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2470 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002471
Walter Dörwald067db482006-03-15 22:17:27 +00002472- Patch #1359365: Calling next() on a closed StringIO.String object raises
2473 a ValueError instead of a StopIteration now (like file and cString.String do).
2474 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2475 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002476
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002477- A regrtest option -w was added to re-run failed tests in verbose mode.

2483 grew an optional 'generation' argument.
2484
Martin v. Löwisfbab90e2006-03-05 13:36:04 +00002485- A library msilib to generate Windows Installer files, and a distutils

2487
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002488- PEP 343: new module contextlib.py defines decorator @contextmanager
2489 and helpful context managers nested() and closing().
2490
Martin v. Löwis415ed932006-02-27 19:56:30 +00002491- The compiler package now supports future imports after the module docstring.
2492

2495
Georg Brandlc98eeed2006-02-19 14:57:47 +00002496- Patch #1215184: FileInput now can be given an opening hook which can

Martin v. Löwis3e865952006-01-24 15:51:21 +00002525 specifications, raises IOErrors when proxies for unsupported protocols
2526 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00002549 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2550 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2551 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2552 Ronald L. Rivest offered this advice for Python:
2553
2554 "The consensus of researchers in this area (at least as
2555 expressed at the NIST Hash Function Workshop 10/31/05),
2556 is that SHA-256 is a good choice for the time being, but
2557 that research should continue, and other alternatives may
2558 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002559
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002560- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandl532efab2005-08-24 22:34:21 +00002605
Georg Brandlb9256022005-08-24 18:46:39 +00002606- Patch #1062060: urllib.urlretrieve() now raises a new exception, named
2607 ContentTooShortException, when the actually downloaded size does not
2608 match the Content-Length header.
2609
Martin v. Löwis0a5d4a22005-08-24 14:55:22 +00002610- Bug #1121494: distutils.dir_utils.mkpath now accepts Unicode strings.
2611

2613 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002614 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002615

Raymond Hettinger8bfa8932005-07-15 06:53:35 +00002634 Patch #1209527 (Contributed by Connelly).
2635
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00002636- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
2637 to W3C name (404 -> 'Not Found'). RFE #1216944.
2638
Georg Brandl9e43acf2005-07-04 17:16:07 +00002639- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2640 as this can cause problems with apps closing all file descriptors.

Raymond Hettingerda99d1c2005-06-21 07:43:58 +00002652- The tokenize module now detects and reports indentation errors.
2653 Bug #1224621.
2654
Raymond Hettinger68c04532005-06-10 11:05:19 +00002655- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002656 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002657 the generate_tokens() function now accepts a callable argument that
2658 terminates by raising StopIteration.
2659
Georg Brandl9166e1a2005-06-04 09:20:03 +00002660- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2661
Georg Brandl268e61c2005-06-03 14:28:50 +00002662- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2663 component of the path.
2664
Skip Montanaro174dd222005-05-14 20:54:16 +00002665- Patch #1120353: The xmlrpclib module provides better, more transparent,
2666 support for datetime.{datetime,date,time} objects. With use_datetime set
2667 to True, applications shouldn't have to fiddle with the DateTime wrapper
2668 class at all.
2669
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002670- distutils.commands.upload was added to support uploading distribution
2671 files to PyPI.
2672
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002673- distutils.commands.register now encodes the data as UTF-8 before posting
2674 them to PyPI.
2675
Raymond Hettinger267b8682005-03-27 10:47:39 +00002676- decimal operator and comparison methods now return NotImplemented
2677 instead of raising a TypeError when interacting with other types. This
2678 allows other classes to implement __radd__ style methods and have them
2679 work as expected.
2680
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002681- Bug #1163325: Decimal infinities failed to hash. Attempting to
2682 hash a NaN raised an InvalidOperation instead of a TypeError.
2683
Tim Petersecc6e6a2005-07-10 22:30:55 +00002684- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002685 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2686

2718
Guido van Rossumd0641422005-02-03 15:01:24 +00002719- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2720 disables recursive traversal through instance attributes, which can
2721 be exploited in various ways.
2722
Tim Peterse3547fd2005-12-16 23:13:57 +00002723- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002724 flags on the HTTP listening socket.
2725
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002726- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2727 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2728
Fred Drakefbdeaad2006-07-29 16:56:15 +00002729- Patches #893642, #1039083: add allow_none, encoding arguments to
2730 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002731
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002732- Bug #1110478: Revert os.environ.update to do putenv again.
2733
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002734- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2735
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002736- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2737
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002738- Enhancements to the csv module:
2739
2740 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002741 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002742 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002743 + Dialect parameter parsing has been re-implemented to improve error
2744 reporting.
2745 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2746 dictates.
2747 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002748 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002749 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002750 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2751 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002752 + reader now allows \r characters to be quoted (previously it only allowed
2753 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002754 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002755 + Dialect classes passed to the module are no longer instantiated by
2756 the module before being parsed (the former validation scheme required
2757 this, but the mechanism was unreliable).
2758 + The dialect registry now contains instances of the internal
2759 C-coded dialect type, rather than references to python objects.
2760 + the internal c-coded dialect type is now immutable.
2761 + register_dialect now accepts the same keyword dialect specifications
2762 as the reader and writer, allowing the user to register dialects
2763 without first creating a dialect class.
2764 + a configurable limit to the size of parsed fields has been added -
2765 previously, an unmatched quote character could result in the entire
2766 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002767 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002768 the parser field size limit (returning the former limit). The initial
2769 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002770 + A line_num attribute has been added to the reader object, which tracks
2771 the number of lines read from the source iterator. This is not
2772 the same as the number of records returned, as records can span
2773 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002774 + reader and writer objects were not being registered with the cyclic-GC.
2775 This has been fixed.
2776
Brett Cannone6539c42005-01-08 02:43:53 +00002777- _DummyThread objects in the threading module now delete self.__block that is
2778 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2779 lock primitives tend to be limited in number and thus should not be wasted on
2780 a _DummyThread object. Fixes bug #1089632.
2781
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002782- The imghdr module now detects Exif files.
2783
Raymond Hettinger6065d322004-12-20 23:51:53 +00002784- StringIO.truncate() now correctly adjusts the size attribute.
2785 (Bug #951915).
2786
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002787- locale.py now uses an updated locale alias table (built using
2788 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2789 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002790 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002791
Raymond Hettinger3557f422004-12-07 12:02:02 +00002792- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2793
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002794- the pickle module no longer accepts the deprecated None option in the
2795 args tuple returned by __reduce__().
2796
Brett Cannon84667c02004-12-07 03:25:18 +00002797- optparse now optionally imports gettext. This allows its use in setup.py.
2798
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002799- the pickle module no longer uses the deprecated bin parameter.
2800
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002801- the shelve module no longer uses the deprecated binary parameter.
2802
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002803- the pstats module no longer uses the deprecated ignore() method.
2804
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002805- the filecmp module no longer uses the deprecated use_statcache argument.
2806
Raymond Hettinger664347b2004-12-04 21:21:53 +00002807- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2808 extended or overridden by subclasses. Formerly, the subclassed method would
2809 be ignored by the rest of the module. (Bug #1078905).
2810
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002811- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002812 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002813
Walter Dörwald36733692004-12-22 12:50:50 +00002814- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2815 once when a size argument is given. This prevents a buffer overflow in the
2816 tokenizer with very long source lines.
2817
Barry Warsaw538561e2006-01-01 21:48:54 +00002818- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2819 immediately after creating the object, without any intervening
2820 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002821
Skip Montanaro05885812005-01-16 20:48:27 +00002822- The reconvert.quote function can now emit triple-quoted strings. The
2823 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002824
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002825- ``UserString.MutableString`` now supports negative indices in
2826 ``__setitem__`` and ``__delitem__``
2827
Greg Ward40407942005-03-05 02:53:17 +00002828- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2829 correctly.
2830
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002831- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2832 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2833 character even if the user has passed a size parameter to get a proper
2834 line ending. Remove the special handling of a "\r\n" that has been split
2835 between two lines.
2836
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002837- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2838 about illegal code points. The codec now supports PEP 293 style error
2839 handlers.
2840
Walter Dörwald78a78b02005-09-01 12:04:29 +00002841- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002842 from the input stream, so that the output is a byte string in the correct
2843 encoding instead of a unicode string.

Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002845- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2846 considering it exactly like a '*'.
2847
Walter Dörwald007f8df2005-10-09 19:42:27 +00002848- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2849 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002850
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002851- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2852
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002853- Patch #1413711: Certain patterns of differences were making difflib
2854 touch the recursion limit.
2855
Walter Dörwald58917a62006-03-31 15:26:22 +00002856- Bug #947906: An object oriented interface has been added to the calendar
2857 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002858 called as a script (e.g. via ``python -mcalendar``). Localized month and
2859 weekday names can be ouput (even if an exotic encoding is used) using
2860 special classes that use unicode.

2863-----
2864
Neal Norwitz602d3392006-03-31 08:21:40 +00002865- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2866 by using -mieee gcc option.
2867

2869
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002870- Build support for Win64-AMD64 was added.
2871
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002872- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2873
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002874- Patch #881820: look for openpty and forkpty also in libbsd.
2875
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002876- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2877 The zlib module is now builtin on Windows.
2878
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002879- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2880
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002881- Bug #1189330: configure did not correctly determine the necessary
2882 value of LINKCC if python was built with GCC 4.0.
2883
Trent Mick8321b422005-07-26 02:29:21 +00002884- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2885 vulnerability in zlib 1.2.1 and 1.2.2.
2886
Brett Cannon08cd5982005-04-24 22:26:38 +00002887- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2888 flags that change binary compatibility. Changes were also made to
2889 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002890 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002891
Bob Ippolitoed233462005-03-29 13:47:59 +00002892- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2893 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2894 no longer exists). This configure patch makes things right.
2895
Martin v. Löwise2713be2005-03-08 15:03:08 +00002896- Bug #1158607: Build with --disable-unicode again.
2897
Brett Cannon46d96232005-02-16 00:07:19 +00002898- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2899 defined. Discovered as a result of not being able to build on OS X.
2900
Brett Cannon516592f2004-12-07 00:42:59 +00002901- setup.py now uses the directories specified in LDFLAGS using the -L option
2902 and in CPPFLAGS using the -I option for adding library and include
2903 directories, respectively, for compiling extension modules against. This has
2904 led to the core being compiled using the values in CPPFLAGS. It also removes
2905 the need for the special-casing of both DarwinPorts and Fink for darwin since
2906 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2907 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2908 Fink, ``-I/opt/local/include`` for DarwinPorts).
2909
Brett Cannon43802422005-02-10 20:48:03 +00002910- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2911 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2912 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2913 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002915C API
2916-----
2917
Tim Petersc9d78aa2006-03-26 23:27:58 +00002918- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2919 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2920 is obtained via the ``PyObject_`` family, it must be released via the
2921 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2922 always been officially true, but when Python's small-object allocator was
2923 introduced, an attempt was made to cater to a few extension modules
2924 discovered at the time that obtained memory via ``PyObject_New`` but
2925 released it via ``PyMem_DEL``. It's years later, and if such code still
2926 exists it will fail now (probably with segfaults, but calling wrong
2927 low-level memory management functions can yield many symptoms).
2928
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002929- Added a C API for set and frozenset objects.
2930

2932
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002933- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2934 mapping argument now. This string is used as a mapping table. Byte values
2935 greater than the length of the string and 0xFFFE are treated as undefined
2936 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00002942- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002943
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002944- Patch #1276356: New resource "urlfetch" is implemented. This enables
2945 even impatient people to run tests that require remote files.
