679-----------------
680
Neal Norwitz0bcafac2006-09-11 08:51:17 +0000681- Make _PyGILState_NoteThreadState() static, it was not used anywhere
682 outside of pystate.c and should not be necessary.
683
Brett Cannon19d76c52006-09-09 07:18:44 +0000684- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
685 allows calling unicode() on exceptions classes directly to succeed.
686
Georg Brandlecab6232006-09-06 06:47:02 +0000687- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

703 head is the original string if sep was not found.
704
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000705- Bug #1520864: unpacking singleton tuples in list comprehensions and
706 generator expressions (x for x, in ... ) works again. Fixing this problem
707 required changing the .pyc magic number. This means that .pyc files
708 generated before 2.5c2 will be regenerated.

822
Neal Norwitz24b6f202006-09-05 04:43:56 +0000823- Fix infinite recursion when subclassing long and overriding __hash__.
824
825- Fix concatenation (+=) of long strings.
826
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000827- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000828 compared equal or unequal to a string and a UnicodeDecodeError
829 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000830
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000831 Instead, the equal (==) and unequal (!=) comparison operators will
832 now issue a UnicodeWarning and interpret the two objects as
833 unequal. The UnicodeWarning can be filtered as desired using
834 the warning framework, e.g. silenced completely, turned into an
835 exception, logged, etc.
836
837 Note that compare operators other than equal and unequal will still
838 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000839
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000840- Fix segfault when doing string formatting on subclasses of long.
841
842- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
843 with new-style classes.
844
845- Fix bug related to __len__ functions returning negative values with
846 classic classes.
847
848- Patch #1538606, Fix __index__() clipping. There were some problems
849 discovered with the API and how integers that didn't fit into Py_ssize_t
850 were handled. This patch attempts to provide enough alternatives
851 to effectively use __index__.
852
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000853- Bug #1536021: __hash__ may now return long int; the final hash
854 value is obtained by invoking hash on the long int.
855
Thomas Hellerab1049c2006-08-08 17:37:00 +0000856- Bug #1536786: buffer comparison could emit a RuntimeWarning.

859 sys.stdin is closed.
860
Thomas Heller74d36f02006-08-04 18:17:40 +0000861- On Windows, the PyErr_Warn function is now exported from
862 the Python dll again.
863
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000864- Bug #1191458: tracing over for loops now produces a line event
865 on each iteration. Fixing this problem required changing the .pyc
866 magic number. This means that .pyc files generated before 2.5c1
867 will be regenerated.
868
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000869- Bug #1333982: string/number constants were inappropriately stored
870 in the byte code and co_consts even if they were not used, ie
871 immediately popped off the stack.

880 generated for generator expressions.
881
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000882- The distutils version has been changed to 2.5.0. The change to
883 keep it programmatically in sync with the Python version running
884 the code (introduced in 2.5b3) has been reverted. It will continue
885 to be maintained manually as static string literal.
886
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000887- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000888 and this cannot be converted to the required C type, an exception is
889 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000890 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000891
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000892- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000893 an exception.

Tim Peterscbdd3502006-09-05 01:47:53 +0000895- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000896 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000897 workarounds for clocks with low resolution, to stop the code yielding
898 duplicate UUIDs.
899
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000900- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
901 before raising SystemExit, allowing IDLE to honor quit() and exit().
902
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000903- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
904
Georg Brandl7a1af772006-08-14 21:55:28 +0000905- Patch #1536071: trace.py should now find the full module name of a
906 file correctly even on Windows.
907
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000908- logging's atexit hook now runs even if the rest of the module has
909 already been cleaned up.
910
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000911- Bug #1112549, fix DoS attack on cgi.FieldStorage.

Neal Norwitzff4b63b2006-08-04 04:50:21 +0000913- Bug #1531405, format_exception no longer raises an exception if
914 str(exception) raised an exception.
915
Neil Schemenauer06ded092006-08-04 16:20:30 +0000916- Fix a bug in the ``compiler`` package that caused invalid code to be
917 generated for nested functions.

928 raises the correct exceptions.
929
Thomas Heller1ce433e2006-08-14 16:20:04 +0000930- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
931 '-no-stack-protector' compiler flag for OpenBSD has been removed.
932
Thomas Heller86720042006-08-14 11:17:48 +0000933- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
934 uses the _as_parameter_ attribute when objects are passed to foreign
935 function calls. The ctypes version number was changed to 1.0.1.
936
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000937- Bug #1530559, struct.pack raises TypeError where it used to convert.
938 Passing float arguments to struct.pack when integers are expected
939 now triggers a DeprecationWarning.

966 code in OpenSSL.
967
Thomas Hellerdb7b4432006-08-04 19:49:31 +0000968- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

977
Tim Peters4643c2f2006-08-10 22:45:34 +0000978- Bug #1069160. Internal correctness changes were made to
979 ``PyThreadState_SetAsyncExc()``. A test case was added, and
980 the documentation was changed to state that the return value
981 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +0000984What's New in Python 2.5 beta 3?
985================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000986
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000987*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000988
989Core and builtins
990-----------------
991
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000992- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000993 returned a long (see PEP 353).
994
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000995- Bug #1515471: string.replace() accepts character buffers again.
996
Neal Norwitz07aadb12006-07-30 06:55:48 +0000997- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
998 This provides the proper warning for struct.pack().
999 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1000
Neal Norwitz0d62a062006-07-30 06:53:31 +00001001- Patch #1531113: Fix augmented assignment with yield expressions.
1002 Also fix a SystemError when trying to assign to yield expressions.
1003
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001004- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1005 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1006 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1007 excessive filesystem operations during imports.
1008
Tim Petersbc24eee2006-07-27 01:14:53 +00001009- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1010 operations on signed longs that are formally undefined by C.
1011 Unfortunately, at least one compiler now cares about that, so complicated
1012 the code to make that compiler happy again.
1013
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001014- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1015
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001016- Patch #1232023: Stop including current directory in search
1017 path on Windows.
1018
Neal Norwitze1fdb322006-07-21 05:32:28 +00001019- Fix some potential crashes found with failmalloc.
1020
Neal Norwitze7563102006-07-17 01:00:16 +00001021- Fix warnings reported by Klocwork's static analysis tool.
1022
Neal Norwitz84be93b2006-07-16 01:50:38 +00001023- Bug #1512814, Fix incorrect lineno's when code within a function
1024 had more than 255 blank lines.
1025
Georg Brandl9dceedb2006-07-12 15:31:17 +00001026- Patch #1521179: Python now accepts the standard options ``--help`` and
1027 ``--version`` as well as ``/?`` on Windows.
1028
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001029- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001030 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001031 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001032
Tim Peters112aad32006-07-19 00:03:19 +00001033- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001034 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001035 new ``sys._current_frames()`` returns a dictionary with one entry,
1036 mapping the faux "thread id" 0 to the current frame.
1037
Ronald Oussoren3075e162006-07-25 20:28:55 +00001038- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001039
Ronald Oussoren3075e162006-07-25 20:28:55 +00001040
Neal Norwitza1f10902006-07-12 07:28:29 +00001041Library
1042-------
1043
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001044- Correction of patch #1455898: In the mbcs decoder, set final=False
1045 for stream decoder, but final=True for the decode function.
1046
Georg Brandl07fec3a2006-08-01 18:49:24 +00001047- os.urandom no longer masks unrelated exceptions like SystemExit or
1048 KeyboardInterrupt.
1049
Tim Peters4643c2f2006-08-10 22:45:34 +00001050- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001051 shutil.copytree on Windows
1052
Georg Brandle34ac7c2006-07-30 11:07:23 +00001053- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1054 refers to file descriptors, not file objects.
1055
Tim Peterscbdd3502006-09-05 01:47:53 +00001056- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001057 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001058 #1513611, and probably others.
1059
Georg Brandledd9b0d2006-07-29 09:33:26 +00001060- Bug #1441397: The compiler module now recognizes module and function
1061 docstrings correctly as it did in Python 2.4.
1062
Tim Peters6f681472006-07-27 23:44:37 +00001063- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1064 lost that tests are sorted by name before being run. This rarely
1065 matters for well-written tests, but can create baffling symptoms if
1066 side effects from one test to the next affect outcomes. ``DocTestFinder``
1067 has been changed to sort the list of tests it returns.
1068
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001069- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001070 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001071
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001072- Bug #978833: Really close underlying socket in _socketobject.close.
1073
Georg Brandldb232dc2006-08-20 13:15:43 +00001074- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1075 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001076
Georg Brandlcf0c1722006-07-26 07:23:32 +00001077- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1078 to recursive calls and call it with the failing package name.
1079
Martin v. Löwis0b483032006-07-25 09:53:12 +00001080- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1081
Georg Brandlc13c34c2006-07-24 14:09:56 +00001082- Patch #1515343: Fix printing of deprecated string exceptions with a
1083 value in the traceback module.
1084
Greg Ward48fae7a2006-07-23 16:05:51 +00001085- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1086
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001087- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1088
Brett Cannoncaebe222006-07-18 04:41:36 +00001089- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1090 argument tuple. For arguments where zero is illegal, the value is forced to
1091 the minimum value that is correct. This is to support an undocumented but
1092 common way people used to fill in inconsequential information in the time
1093 tuple pre-2.4.
1094
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001095- Patch #1220874: Update the binhex module for Mach-O.
1096
Barry Warsawb110bad2006-07-21 14:51:07 +00001097- The email package has improved RFC 2231 support, specifically for
1098 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1099 (name*0=<blah>) parameter continuations. This may change the types of
1100 values returned from email.message.Message.get_param() and friends.
1101 Specifically in some cases where non-encoded continuations were used,
1102 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1103 will just return the string (since non-encoded continuations don't have
1104 charset and language parts).
1105
1106 Also, whereas % values were decoded in all parameter continuations, they are
1107 now only decoded in encoded parameter parts.
1108
Ronald Oussoren3075e162006-07-25 20:28:55 +00001109- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1110
1111- Bug #1517996: IDLE now longer shows the default Tk menu when a
1112 path browser, class browser or debugger is the frontmost window on MacOS X
1113
Barry Warsaw00decd72006-07-27 23:43:15 +00001114- Patch #1520294: Support for getset and member descriptors in types.py,
1115 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1116 of an object against these built-in types and more importantly, for getting
1117 their docstrings printed in the interactive interpreter's help() function.

1122
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001123- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1124 a socket operation on a socket with a timeout, the exception will be
1125 caught correctly. Previously, the exception was not caught.
1126
Thomas Heller1393d6a2006-07-28 21:43:20 +00001127- Patch #1529514: The _ctypes extension is now compiled on more
1128 openbsd target platforms.
1129
Tim Peters9cab5932006-07-28 00:30:00 +00001130- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1131 a memory leak, affecting pickles and deep copies.
1132
Tim Petersbc24eee2006-07-27 01:14:53 +00001133- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1137
Thomas Hellerce049a02006-07-14 17:51:14 +00001138- Patch #1521817: Index range checking on ctypes arrays containing
1139 exactly one element enabled again. This allows iterating over these
1140 arrays, without the need to check the array size before.
1141
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001142- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001143 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001144 /dev/null in certain cases; this is now fixed.
1145
Thomas Heller47d7a062006-07-12 08:43:47 +00001146- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1147 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001148
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001149- Because of a misspelled preprocessor symbol, ctypes was always
1150 compiled without thread support; this is now fixed.
1151
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001152- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1153 methods now allow their database parameter to be None as the
1154 sleepycat API allows.
1155
Matt Flemingec926502006-07-28 11:27:27 +00001156- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1157 bluetooth API compared with Linux and FreeBSD.
1158
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001159Tests
1160-----
1161
1162- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1163 how long the test file should take to play. Now accepts taking 2.93 secs
1164 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1165
Georg Brandl4793aa32006-07-28 18:31:39 +00001166- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1167 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1168 run via ``regrtest.py``. Now they do.

1178- PythonLauncher now works correctly when the path to the script contains
1179 characters that are treated specially by the shell (such as quotes).
1180
1181- Bug #1527397: PythonLauncher now launches scripts with the working directory
1182 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001183 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001184 expect.

Georg Brandlad29e632006-06-21 17:45:17 +00001191
1192Core and builtins
1193-----------------
1194
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001195- Bug #1441486: The literal representation of -(sys.maxint - 1)
1196 again evaluates to a int object, not a long.
1197
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001198- Bug #1501934: The scope of global variables that are locally assigned
1199 using augmented assignment is now correctly determined.
1200
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001201- Bug #927248: Recursive method-wrapper objects can now safely
1202 be released.
1203
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001204- Bug #1417699: Reject locale-specific decimal point in float()
1205 and atof().
1206
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001207- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1208 omit a default "error" argument for NULL pointer. This allows
1209 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001210
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001211- Bug #1519018: 'as' is now validated properly in import statements.
1212
Neal Norwitz28746ab2006-07-09 22:14:42 +00001213- On 64 bit systems, int literals that use less than 64 bits are
1214 now ints rather than longs.
1215
Neal Norwitzed657552006-07-10 00:04:44 +00001216- Bug #1512814, Fix incorrect lineno's when code at module scope
1217 started after line 256.
1218
Tim Peters32a83612006-07-10 21:08:24 +00001219- New function ``sys._current_frames()`` returns a dict mapping thread
1220 id to topmost thread stack frame. This is for expert use, and is
1221 especially useful for debugging application deadlocks. The functionality
1222 was previously available in Fazal Majid's ``threadframe`` extension
1223 module, but it wasn't possible to do this in a wholly threadsafe way from
1224 an extension.
1225

1227-------
1228
Martin v. Löwis77621582006-07-30 13:27:31 +00001229- Bug #1257728: Mention Cygwin in distutils error message about a missing
1230 VS 2003.
1231
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001232- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1233
Tim Peters32a83612006-07-10 21:08:24 +00001234- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001235 environment variable to be set in order to the SDK environment
1236 for finding the compiler, include files, etc.
1237
Martin v. Löwis388a8c22006-07-06 19:28:03 +00001238- Bug #1515998: Properly generate logical ids for files in bdist_msi.
1239
Nick Coghlan2d792252006-07-06 13:47:18 +00001240- warnings.py now ignores ImportWarning by default
1241
Thomas Woutersadd19112006-07-05 11:03:49 +00001242- string.Template() now correctly handles tuple-values. Previously,
1243 multi-value tuples would raise an exception and single-value tuples would
1244 be treated as the value they contain, instead.
1245
Martin v. Löwisede77f52006-07-03 13:01:35 +00001246- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1247 even if some data are received.
1248
Martin v. Löwis45482392006-07-03 12:28:58 +00001249- Bug #1267547: Put proper recursive setup.py call into the
1250 spec file generated by bdist_rpm.
1251
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001252- Bug #1514693: Update turtle's heading when switching between
1253 degrees and radians.
1254
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001255- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001256 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001257
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001258- Bug #1514703: Only setup canvas window in turtle when the canvas
1259 is created.
1260
Martin v. Löwis7596e832006-07-01 15:33:37 +00001261- Bug #1513223: .close() of a _socketobj now releases the underlying

1265 attribute values.
1266
1267- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1268 sgmllib ('[' and ']' were not accepted).
1269
Georg Brandl1be63af2006-06-28 20:23:25 +00001270- Fix a bug in the turtle module's end_fill function.
1271
Brett Cannon53ab5b72006-06-22 16:49:14 +00001272- Bug #1510580: The 'warnings' module improperly required that a Warning
1273 category be either a types.ClassType and a subclass of Warning. The proper
1274 check is just that it is a subclass with Warning as the documentation states.
1275
Georg Brandlad29e632006-06-21 17:45:17 +00001276- The compiler module now correctly compiles the new try-except-finally
1277 statement (bug #1509132).
1278
Neal Norwitz60373cd2006-06-22 06:30:50 +00001279- The wsgiref package is now installed properly on Unix.
1280
Vinay Sajip28e57612006-07-01 10:45:20 +00001281- A bug was fixed in logging.config.fileConfig() which caused a crash on
1282 shutdown when fileConfig() was called multiple times.
1283
Gerhard Häring762fbd32006-07-02 17:48:30 +00001284- The sqlite3 module did cut off data from the SQLite database at the first
1285 null character before sending it to a custom converter. This has been fixed
1286 now.
1287
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001288Extension Modules
1289-----------------
1290
Tim Peters112aad32006-07-19 00:03:19 +00001291- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1292 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1293 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001294
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001295- Assigning None to pointer type fields in ctypes structures possible
1296 overwrote the wrong fields, this is fixed now.
1297
1298- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1299 on non-Windows platforms.
1300
1301- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1302 integer or long, without range checking.
1303
1304- Patch #1517790: It is now possible to use custom objects in the ctypes
1305 foreign function argtypes sequence as long as they provide a from_param
1306 method, no longer is it required that the object is a ctypes type.
1307
1308- The '_ctypes' extension module now works when Python is configured
1309 with the --without-threads option.
1310
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001311- Bug #1513646: os.access on Windows now correctly determines write
1312 access, again.
1313
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001314- Bug #1512695: cPickle.loads could crash if it was interrupted with
1315 a KeyboardInterrupt.
1316
Neal Norwitza12aa882006-07-06 06:45:08 +00001317- Bug #1296433: parsing XML with a non-default encoding and
1318 a CharacterDataHandler could crash the interpreter in pyexpat.
1319
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001320- Patch #1516912: improve Modules support for OpenVMS.

1324
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001325- Automate Windows build process for the Win64 SSL module.
1326
Tim Peters32a83612006-07-10 21:08:24 +00001327- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001328 Previously, the slight difference could cause compilation errors of the
1329 'zlib' module on systems with more than one version of zlib.
1330
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001331- The MSI compileall step was fixed to also support a TARGETDIR
1332 with spaces in it.
1333
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001334- Bug #1517388: sqlite3.dll is now installed on Windows independent
1335 of Tcl/Tk.
1336
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001337- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001338 trying to be installed even though it's empty.

Neal Norwitzb15ac312006-06-29 04:10:08 +00001340Tests
1341-----
1342
1343- Call os.waitpid() at the end of tests that spawn child processes in order
1344 to minimize resources (zombies).
1345
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001346Documentation
1347-------------
1348
Nick Coghlan2d792252006-07-06 13:47:18 +00001349- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1350 documentation for the warnings module.
1351
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001352- Patch #1509163: MS Toolkit Compiler no longer available.
1353

Nick Coghlanc649ec52006-05-29 12:43:05 +00001357What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +00001358================================
Anthony Baxter51bcb682006-04-05 14:51:42 +00001359
Anthony Baxterd1136802006-06-19 12:04:15 +00001360*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +00001361
1362Core and builtins
1363-----------------
1364
Georg Brandla56b9152006-06-19 06:35:54 +00001365- Patch #1507676: Error messages returned by invalid abstract object operations
1366 (such as iterating over an integer) have been improved and now include the
1367 type of the offending object to help with debugging.
1368
Brett Cannonea3912b2006-06-13 21:46:41 +00001369- Bug #992017: A classic class that defined a __coerce__() method that returned
1370 its arguments swapped would infinitely recurse and segfault the interpreter.
1371
Neal Norwitz909eb122006-06-12 02:13:21 +00001372- Fix the socket tests so they can be run concurrently.
1373
Neal Norwitzb9845e72006-06-12 02:11:18 +00001374- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001375 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001376
Brett Cannon22565aa2006-06-09 22:31:23 +00001377- Bug #532646: object.__call__() will continue looking for the __call__
1378 attribute on objects until one without one is found. This leads to recursion
1379 when you take a class and set its __call__ attribute to an instance of the
1380 class. Originally fixed for classic classes, but this fix is for new-style.
1381 Removes the infinite_rec_3 crasher.
1382
Georg Brandl24250812006-06-09 18:45:48 +00001383- The string and unicode methods startswith() and endswith() now accept
1384 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1385
Brett Cannonde3b0522006-06-08 17:00:45 +00001386- Buffer objects, at the C level, never used the char buffer
1387 implementation even when the char buffer for the wrapped object was
1388 explicitly requested (originally returned the read or write buffer).
1389 Now a TypeError is raised if the char buffer is not present but is
1390 requested.
1391
Georg Brandlddbaa662006-06-04 21:56:52 +00001392- Patch #1346214: Statements like "if 0: suite" are now again optimized
1393 away like they were in Python 2.4.
1394
Georg Brandlb7c8f542006-05-27 12:30:25 +00001395- Builtin exceptions are now full-blown new-style classes instead of
1396 instances pretending to be classes, which speeds up exception handling
1397 by about 80% in comparison to 2.5a2.
1398
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001399- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1400 Unicode 4.1.
1401
Georg Brandlf4ef1162006-05-26 18:03:31 +00001402- Patch #921466: sys.path_importer_cache is now used to cache valid and
1403 invalid file paths for the built-in import machinery which leads to
1404 fewer open calls on startup.
1405
Tim Peters696cf432006-05-24 21:10:40 +00001406- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1407 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1408 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1409 the number of input digits (it was and remains linear-time for bases
1410 2, 4, 8, 16 and 32).
1411
Tim Petersb713ec22006-05-23 18:45:30 +00001412- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1413 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1414 an integer close to ``sys.maxint``. This was repaired by patch
1415 #1335972, which also gives a nice speedup.
1416
Richard Jonescebbefc2006-05-23 18:28:17 +00001417- Patch #1337051: reduced size of frame objects.
1418
1419- PyErr_NewException now accepts a tuple of base classes as its
1420 "base" parameter.
1421
Richard Jones7c88dcc2006-05-23 10:37:38 +00001422- Patch #876206: function call speedup by retaining allocated frame
1423 objects.
1424
Georg Brandl7b90e162006-05-18 07:01:27 +00001425- Bug #1462152: file() now checks more thoroughly for invalid mode
1426 strings and removes a possible "U" before passing the mode to the
1427 C library function.
1428
Neal Norwitz1004a532006-05-15 07:17:23 +00001429- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1430
Neal Norwitz373f0a72006-05-15 07:04:36 +00001431- Bug #1487966: Fix SystemError with conditional expression in assignment
1432
Martin v. Löwis879768d2006-05-11 13:28:43 +00001433- WindowsError now has two error code attributes: errno, which carries
1434 the error values from errno.h, and winerror, which carries the error
1435 values from winerror.h. Previous versions put the winerror.h values
1436 (from GetLastError()) into the errno attribute.
1437
Martin v. Löwis77736712006-05-04 05:51:03 +00001438- Patch #1475845: Raise IndentationError for unexpected indent.
1439
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001440- Patch #1479181: split open() and file() from being aliases for each other.
1441
Tim Peters44bd9862006-06-01 13:49:23 +00001442- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1443 methods were always silently ignored by dictionaries when comparing keys.
1444 They are now passed through (except when using the C API function
1445 ``PyDict_GetItem()``, whose semantics did not change).
1446
1447- Bug #1456209: In some obscure cases it was possible for a class with a
1448 custom ``__eq__()`` method to confuse dict internals when class instances
1449 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1450 No, you don't have any code that did this ;-)

Trent Mick960a3f82006-06-28 20:30:41 +00001455- Bug #1295808: expat symbols should be namespaced in pyexpat
1456
1457- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1458
Brett Cannon6ee7d012006-06-08 16:23:04 +00001459- Change binascii.hexlify to accept a read-only buffer instead of only a char
1460 buffer and actually follow its documentation.
1461
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001462- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1463
Nick Coghlanc649ec52006-05-29 12:43:05 +00001464- Patch #1478788 (modified version): The functional extension module has
1465 been renamed to _functools and a functools Python wrapper module added.
1466 This provides a home for additional function related utilities that are
1467 not specifically about functional programming. See PEP 309.
1468
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001469- Patch #1493701: performance enhancements for struct module.

1472
Georg Brandl8d3342b2006-05-16 07:38:27 +00001473- Patch #1435422: zlib's compress and decompress objects now have a
1474 copy() method.

Andrew MacIntyre92913322006-06-13 15:04:24 +00001476- Patch #1454481: thread stack size is now tunable at runtime for thread
1477 enabled builds on Windows and systems with Posix threads support.
1478
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001479- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1480 (up to the system limit of 32K characters).
1481
1482- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1483 As a result, these functions now raise WindowsError instead of OSError.
1484
Tim Peters7a822da2006-05-25 21:50:17 +00001485- ``time.clock()`` on Win64 should use the high-performance Windows
1486 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1487 Windows platforms).
1488
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001489- Calling Tk_Init twice is refused if the first call failed as that
1490 may deadlock.
1491
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001492- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1493 accept it without potentially using an uninitialized pointer.
1494
1495- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1496 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1497 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001498
Gregory P. Smith372b5832006-06-05 18:48:21 +00001499- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001500 [pybsddb project SF patch number 1466734]
1501
Gregory P. Smith372b5832006-06-05 18:48:21 +00001502- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1503 parameter is supplied. [SF pybsddb bug #1477863]
1504
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001505- bsddb: the __len__ method of a DB object has been fixed to return correct
1506 results. It could previously incorrectly return 0 in some cases.
1507 Fixes SF bug 1493322 (pybsddb bug 1184012).
1508
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001509- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1510 aborts the db transaction safely when a modifier callback fails.
1511 Fixes SF python patch/bug #1408584.
1512
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001513- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001514 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001515 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1516 database calls that would previously deadlock. [SF python bug #775414]
1517
Vinay Sajip28e57612006-07-01 10:45:20 +00001518- Patch #1446489: add support for the ZIP64 extensions to zipfile.

Georg Brandl83cc0d02006-06-14 08:50:03 +00001539- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1540 mime.types file for determining MIME types.
1541
Georg Brandl2605ca82006-06-14 06:08:31 +00001542- Bug #1339007: Shelf objects now don't raise an exception in their
1543 __del__ method when initialization failed.
1544
Martin v. Löwisd8251432006-06-14 05:21:04 +00001545- Patch #1455898: The MBCS codec now supports the incremental mode for
1546 double-byte encodings.
1547
Tim Peters43898b42006-06-14 04:09:25 +00001548- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1549 guarantee that adjacent triples in the return list always describe
1550 non-adjacent blocks. Previously, a pair of matching blocks could end
1551 up being described by multiple adjacent triples that formed a partition
1552 of the matching pair.
1553
Greg Ward0e0c9f42006-06-11 16:24:11 +00001554- Bug #1498146: fix optparse to handle Unicode strings in option help,
1555 description, and epilog.
1556
Greg Wardd1c797e2006-06-11 14:42:41 +00001557- Bug #1366250: minor optparse documentation error.

Greg Ward7f547402006-06-11 00:40:49 +00001559- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1560 clarify docs.
1561
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001562- The wsgiref package has been added to the standard library.
1563
Nick Coghlan676725d2006-06-08 13:54:49 +00001564- The functions update_wrapper() and wraps() have been added to the functools
1565 module. These make it easier to copy relevant metadata from the original
1566 function when writing wrapper functions.
1567
Tim Petersd6a9eef2006-06-05 01:48:21 +00001568- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1569 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001570
Martin v. Löwis3f767792006-06-04 19:36:28 +00001571- Patch #1359618: Speed up charmap encoder by using a trie structure
1572 for lookup.
1573
Tim Petersd609b1a2006-06-02 23:22:51 +00001574- The functions in the ``pprint`` module now sort dictionaries by key
1575 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1576 if and only if its display required more than one line, although that
1577 wasn't documented. The new behavior increases predictability; e.g.,
1578 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1579
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001580- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1581 (thanks for J. J. Lee).
1582
Georg Brandl2b330372006-05-28 20:23:12 +00001583- Patch #1496206: improve urllib2 handling of passwords with respect to
1584 default HTTP and HTTPS ports.
1585
George Yoshidaf3c65de2006-05-28 16:39:09 +00001586- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1587
Bob Ippolito7298f272006-05-23 18:43:47 +00001588- Patch #1281707: speed up gzip.readline.
1589
Georg Brandlb89316f2006-05-17 15:51:16 +00001590- Patch #1180296: Two new functions were added to the locale module:
1591 format_string() to get the effect of "format % items" but locale-aware,
1592 and currency() to format a monetary number with currency sign.
1593
Georg Brandle3a25832006-05-17 14:56:04 +00001594- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1595 and several features added, such as speed and geometry control.
1596
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001597- Patch #1488881: add support for external file objects in bz2 compressed
1598 tarfiles.
1599
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001600- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1601 stdout arguments, making it possible to redirect input and output
1602 for remote debugging.
1603
1604- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1605 a couple of issues, notably handling of long file names using the
1606 GNU LONGNAME extension.
1607
1608- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1609 new flag when ``name`` is already the name of an option flag.
1610
1611- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1612 package.
1613
1614- Patch #1472854: make the rlcompleter.Completer class usable on non-
1615 UNIX platforms.
1616
1617- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.

1655Core and builtins
1656-----------------
1657
Thomas Heller1b046642006-04-18 18:51:06 +00001658- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1659 by converting these apis from macros into exported functions again:
1660
1661 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1662 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1663 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1664 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1665 PyRun_String Py_CompileString
1666
Martin v. Löwis45294a92006-04-18 06:24:08 +00001667- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1668
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001669- All uses of PyStructSequence_InitType have been changed to initialize
1670 the type objects only once, even if the interpreter is initialized
1671 multiple times.
1672
Neal Norwitz61546162006-04-14 05:20:28 +00001673- Bug #1454485, array.array('u') could crash the interpreter. This was
1674 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1675 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1676
1677- Py_UNICODE is unsigned. It was always documented as unsigned, but
1678 due to a bug had a signed value in previous versions.
1679
Tim Peters3a5e8b12006-04-11 01:44:07 +00001680- Patch #837242: ``id()`` of any Python object always gives a positive
1681 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1682 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001683 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001684 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001685
Tim Peters3a5e8b12006-04-11 01:44:07 +00001686 def __hash__(self):
1687 return id(self) # WRONG
1688
1689 because a hash result must be a (short) Python int but it was always
1690 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001691 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001692 was always usable as a hash value before this patch. That's no longer
1693 necessarily so.
1694
1695- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001696 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001697 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001698 #1454844)
1699
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001700- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1701 involving generators that have paused outside of any ``try`` or ``with``
1702 blocks. (In 2.5a1, a paused generator that was part of a reference
1703 cycle could not be garbage collected, regardless of whether it was
1704 paused in a ``try`` or ``with`` block.)

1717- Bug #1117761: bsddb.*open() no longer raises an exception when using
1718 the cachesize parameter.
1719
1720- Bug #1149413: bsddb.*open() no longer raises an exception when using
1721 a temporary db (file=None) with the 'n' flag to truncate on open.
1722
1723- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1724 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001725
Armin Rigoa9017c32006-04-19 11:50:27 +00001726- Patch #1062014: AF_UNIX sockets under Linux have a special
1727 abstract namespace that is now fully supported.

1730-------
1731
Peter Astrand7d1d4362006-07-14 14:04:45 +00001732- Bug #1223937: subprocess.CalledProcessError reports the exit status
1733 of the process using the returncode attribute, instead of
1734 abusing errno.
1735
Tim Peters711bf302006-04-25 03:31:36 +00001736- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1737 a doctest to be skipped (the code is not run, and the expected output
1738 or exception is ignored).
1739
Nick Coghlanda2268f2006-04-24 04:37:15 +00001740- Fixed contextlib.nested to cope with exceptions being raised and
1741 caught inside exit handlers.
1742
Greg Wardab05edc2006-04-23 03:47:58 +00001743- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1744 hex, octal, or binary; add ``append_const`` action; keep going if
1745 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1746 added ``epilog`` for better help generation).
1747
Tim Peters21fbd572006-04-21 21:18:10 +00001748- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1749 called from a thread spawned as a side effect of importing a module.
1750
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001751- The pydoc module now supports documenting packages contained in
1752 .zip or .egg files.
1753
1754- The pkgutil module now has several new utility functions, such
1755 as ``walk_packages()`` to support working with packages that are either
1756 in the filesystem or zip files.
1757
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001758- The mailbox module can now modify and delete messages from
1759 mailboxes, in addition to simply reading them. Thanks to Gregory
1760 K. Johnson for writing the code, and to the 2005 Google Summer of
1761 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001762
Tim Petersc7605f22006-04-17 21:12:33 +00001763- The ``__del__`` method of class ``local`` in module ``_threading_local``
1764 returned before accomplishing any of its intended cleanup.
1765
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001766- Patch #790710: Add breakpoint command lists in pdb.
1767
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001768- Patch #1063914: Add Tkinter.Misc.clipboard_get().

1771
Anthony Baxtere29002c2006-04-12 12:07:31 +00001772- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1773 Windows. Bug #1469163.
1774
Phillip J. Eby47032112006-04-11 01:07:43 +00001775- The warnings, linecache, inspect, traceback, site, and doctest modules
1776 were updated to work correctly with modules imported from zipfiles or
1777 via other PEP 302 __loader__ objects.
1778
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001779- Patch #1467770: Reduce usage of subprocess._active to processes which

1788
Anthony Baxter51bcb682006-04-05 14:51:42 +00001789Build
1790-----
1791
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001792- The Makefile now has a reindent target, which runs reindent.py on
1793 the library.
1794
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001795- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001798
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001799- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1800 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001801 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001802 CXX from --with-cxx-main, see description in README.
1803
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001804- Patch #1429775: Link extension modules with the shared libpython.
1805
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001806- Fixed a libffi build problem on MIPS systems.
1807
Tim Peters8931ff12006-05-13 23:28:20 +00001808- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1809 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1810 and "%zu" for unsigned integers of type ``size_t``.
1811
Anthony Baxter51bcb682006-04-05 14:51:42 +00001812Tests
1813-----
1814
Nick Coghlanda2268f2006-04-24 04:37:15 +00001815- test_contextlib now checks contextlib.nested can cope with exceptions
1816 being raised and caught inside exit handlers.
1817
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001818- test_cmd_line now checks operation of the -m and -c command switches
1819
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001820- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1821 it separately and by hand. It also wasn't cleaning up its changes to
1822 the current Decimal context.
1823
Thomas Woutersabd08882006-04-26 15:53:30 +00001824- regrtest.py now has a -M option to run tests that test the new limits of
1825 containers, on 64-bit architectures. Running these tests is only sensible
1826 on 64-bit machines with more than two gigabytes of memory. The argument
1827 passed is the maximum amount of memory for the tests to use.
1828
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001829Tools
1830-----

Anthony Baxter51bcb682006-04-05 14:51:42 +00001835Documentation
1836-------------
1837
Tim Petersb06d28c2006-05-12 01:57:59 +00001838- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1839
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001840- PEP 343: Added Context Types section to the library reference
1841 and attempted to bring other PEP 343 related documentation into
1842 line with the implementation and/or python-dev discussions.
1843
Tim Peters8dc73d22006-04-24 02:03:16 +00001844- Bug #1337990: clarified that ``doctest`` does not support examples
1845 requiring both expected output and an exception.
Anthony Baxter51bcb682006-04-05 14:51:42 +00001846

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001848What's New in Python 2.5 alpha 1?
1849=================================
1850
Anthony Baxterebed3f62006-04-03 15:03:44 +00001851*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001852
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001853Core and builtins
1854-----------------
1855
Nick Coghlan43832302006-04-23 17:04:07 +00001856- PEP 338: -m command line switch now delegates to runpy.run_module
1857 allowing it to support modules in packages and zipfiles
1858
Martin v. Löwisc661b882006-04-20 04:54:23 +00001859- On Windows, .DLL is not an accepted file name extension for
1860 extension modules anymore; extensions are only found if they
1861 end in .PYD.
1862
Martin v. Löwisea62d252006-04-03 10:56:49 +00001863- Bug #1421664: sys.stderr.encoding is now set to the same value as
1864 sys.stdout.encoding.
1865
Neal Norwitz92e212f2006-04-03 04:48:37 +00001866- __import__ accepts keyword arguments.
1867
Georg Brandlccadf842006-03-31 18:54:53 +00001868- Patch #1460496: round() now accepts keyword arguments.
1869
Anthony Baxter262c00a2006-03-30 10:53:17 +00001870- Fixed bug #1459029 - unicode reprs were double-escaped.
1871
Hye-Shik Changd478f342006-03-23 12:32:36 +00001872- Patch #1396919: The system scope threads are reenabled on FreeBSD
1873 5.4 and later versions.
1874
Neal Norwitze98ccf62006-03-23 05:39:47 +00001875- Bug #1115379: Compiling a Unicode string with an encoding declaration
1876 now gives a SyntaxError.
1877
Georg Brandlabd1ff82006-03-18 07:59:59 +00001878- Previously, Python code had no easy way to access the contents of a
1879 cell object. Now, a ``cell_contents`` attribute has been added
1880 (closes patch #1170323).
1881
Tim Peterscf79aac2006-03-16 01:14:46 +00001882- Patch #1123430: Python's small-object allocator now returns an arena to
1883 the system ``free()`` when all memory within an arena becomes unused
1884 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1885 freed. Some applications will see a drop in virtual memory size now,
1886 especially long-running applications that, from time to time, temporarily
1887 use a large number of small objects. Note that when Python returns an
1888 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001889 platform C library will in turn return that memory to the operating system.
1890 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001891 appears to be effective at least on Microsoft C and gcc-based systems.
1892 Thanks to Evan Jones for hard work and patience.
1893
Georg Brandl533ff6f2006-03-08 18:09:27 +00001894- Patch #1434038: property() now uses the getter's docstring if there is
1895 no "doc" argument given. This makes it possible to legitimately use
1896 property() as a decorator to produce a read-only property.
1897
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001898- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1899 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1900 of requiring an int or long in slicing and a few other contexts, enabling
1901 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1902
Neal Norwitz995acdf2006-03-07 05:01:00 +00001903- Fixed various bugs reported by Coverity's Prevent tool.
1904
Brett Cannonbf364092006-03-01 04:25:17 +00001905- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1906 new exception base class, BaseException, which has a new message attribute.
1907 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1908 Raising a string exception now raises a DeprecationWarning.
1909
Thomas Woutersfb609f42006-02-28 16:37:25 +00001910- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1911 explicitly relative, using 'from .module import name' to mean 'from the same
1912 package as this module is in. Imports without dots still default to the
1913 old relative-then-absolute, unless 'from __future__ import
1914 absolute_import' is used.
1915
Brett Cannona7446e32006-02-27 23:39:10 +00001916- Properly check if 'warnings' raises an exception (usually when a filter set
1917 to "error" is triggered) when raising a warning for raising string
1918 exceptions.
1919
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001920- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001921 The name was removed from Include/code.h.
1922
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001923- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001924
Guido van Rossum1968ad32006-02-25 22:38:04 +00001925- Patch 1433928:
1926 - The copy module now "copies" function objects (as atomic objects).
1927 - dict.__getitem__ now looks for a __missing__ hook before raising
1928 KeyError.
1929
Tim Peters84ef21c2006-02-28 20:39:06 +00001930- PEP 343: with statement implemented. Needs ``from __future__ import
1931 with_statement``. Use of 'with' as a variable will generate a warning.
1932 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001933 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001934 The following objects have __context__ methods:
1935 - The built-in file type.
1936 - The thread.LockType type.
1937 - The following types defined by the threading module:
1938 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1939 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001940
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001941- Fix the encodings package codec search function to only search
1942 inside its own package. Fixes problem reported in patch #1433198.
1943
1944 Note: Codec packages should implement and register their own
1945 codec search function. PEP 100 has the details.
1946
Tim Peters9ea89d22006-06-04 03:26:02 +00001947- PEP 353: Using ``Py_ssize_t`` as the index type.
1948
1949- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1950 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1951 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1952 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1953 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001954
Neal Norwitzfc76d632006-01-10 06:03:13 +00001955- Patch #1400181, fix unicode string formatting to not use the locale.
1956 This is how string objects work. u'%f' could use , instead of .
1957 for the decimal point. Now both strings and unicode always use periods.
1958
Neal Norwitz671b9e32006-01-09 07:07:12 +00001959- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1960 configure would break checking curses.h.
1961
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001962- Bug #959576: The pwd module is now builtin. This allows Python to be
1963 built on UNIX platforms without $HOME set.
1964
Neal Norwitzc10978f2005-12-19 06:07:16 +00001965- Bug #1072182, fix some potential problems if characters are signed.
1966
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001967- Bug #889500, fix line number on SyntaxWarning for global declarations.
1968
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001969- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1970
Neal Norwitze7214a12005-12-18 05:03:17 +00001971- Support for converting hex strings to floats no longer works.
1972 This was not portable. float('0x3') now raises a ValueError.
1973
Barry Warsaw2a38a862005-12-18 01:27:35 +00001974- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001975 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001976 is now displayed in interactive prompt banner.
1977
Georg Brandlfa166682005-12-17 21:45:17 +00001978- Implementation of PEP 341 - Unification of try/except and try/finally.
1979 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001980 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001981
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001982- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1983 now encodes backslash correctly.
1984
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001985- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1986
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001987- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001988 and long longs.
1989
Neal Norwitz67715f02005-11-09 06:59:35 +00001990- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001991 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001992 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001993
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001994- Replaced most Unicode charmap codecs with new ones using the
1995 new Unicode translate string feature in the builtin charmap
1996 codec; the codecs were created from the mapping tables available
1997 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1998 encodings now include a mapping for the Apple logo)
1999
Tim Peterse3547fd2005-12-16 23:13:57 +00002000- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002001
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002002- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002003
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002004- A new AST parser implementation was completed. The abstract
2005 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002006 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002007
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002008- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002009 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2010
Neal Norwitz708e51a2005-10-03 04:48:15 +00002011- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2012
Neal Norwitz11bd1192005-10-03 00:54:56 +00002013- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2014 Provide a warning when a directory is passed on the command line.
2015
Neal Norwitz40d37812005-10-02 01:48:49 +00002016- Fix segfault with invalid coding.
2017
2018- SF bug #772896: unknown encoding results in MemoryError.
2019
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002020- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002021 supported a __len__() method which evaluated to False when the iterator
2022 was empty.
2023
Guido van Rossum630db602005-09-20 18:49:54 +00002024- On 64-bit platforms, when __len__() returns a value that cannot be
2025 represented as a C int, raise OverflowError.
2026
Skip Montanarof8948ca2005-09-19 03:54:46 +00002027- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002028 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002029
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002030- SF bug #893549: parsing keyword arguments was broken with a few format
2031 codes.
2032
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002033- Changes donated by Elemental Security to make it work on AIX 5.3
2034 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2035 bug #105470: test_pwd fails on 64bit system (Opteron).
2036
Guido van Rossum539c6622005-09-14 17:49:54 +00002037- Changes donated by Elemental Security to make it work on HP-UX 11 on
2038 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2039
Georg Brandl4550b8d2005-08-26 06:43:52 +00002040- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002041 (fixes bug #1119418).
2042
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002043- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2044
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002045- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2046 exceptions that cause a function to exit.
2047
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002048- The implementation of set() and frozenset() was revised to use its
2049 own internal data structure. Memory consumption is reduced by 1/3
2050 and there are modest speed-ups as well. The API is unchanged.
2051
Tim Petersde7990b2005-07-17 23:45:23 +00002052- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2053
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002054- SF bug #1229429: PyObject_CallMethod failed to decrement some
2055 reference counts in some error exit cases.
2056
Tim Petersecc6e6a2005-07-10 22:30:55 +00002057- SF bug #1185883: Python's small-object memory allocator took over
2058 a block managed by the platform C library whenever a realloc specified
2059 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002060 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002061 portable way to copy data from the C-managed block into Python's
2062 small-object space without risking a memory fault. Python's small-object
2063 realloc now leaves such blocks under the control of the platform C
2064 realloc.
2065
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002066- SF bug #1232517: An overflow error was not detected properly when
2067 attempting to convert a large float to an int in os.utime().
2068
Raymond Hettinger3296e692005-06-29 23:29:56 +00002069- SF bug #1224347: hex longs now print with lowercase letters just
2070 like their int counterparts.
2071
Michael W. Hudson188d4362005-06-20 16:52:57 +00002072- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2073 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2074 interpreter states; back out that fix and do a better job (see
2075 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2076 for a longer write-up of the problem).
2077
Michael W. Hudsondf888462005-06-03 14:41:55 +00002078- SF patch #1180995: marshal now uses a binary format by default when
2079 serializing floats.
2080
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002081- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2082 the routines that promise to produce IEEE 754 binary representations
2083 of floats now simply copy bytes around.
2084
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002085- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2086 278.
2087
Brett Cannonc3647ac2005-04-26 03:45:26 +00002088- patch #1109424: int, long, float, complex, and unicode now check for the
2089 proper magic slot for type conversions when subclassed. Previously the
2090 magic slot was ignored during conversion. Semantics now match the way
2091 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002092 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002093 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002094 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002095
Barry Warsawc8d907c2005-04-19 23:43:40 +00002096- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2097 NULL, now raise an AttributeError when attempting to set or delete the
2098 attribute. Previously a TypeError was raised, but this was inconsistent
2099 with the equivalent pure-Python implementation.
2100
Michael W. Hudson774479c2005-04-18 08:46:17 +00002101- It is now safe to call PyGILState_Release() before
2102 PyEval_InitThreads() (note that if there is reason to believe there
2103 are multiple threads around you still must call PyEval_InitThreads()
2104 before using the Python API; this fix is for extension modules that
2105 have no way of knowing if Python is multi-threaded yet).
2106
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002107- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2108 disabled caused a crash.
2109
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002110- Bug #1165306: instancemethod_new allowed the creation of a method
2111 with im_class == im_self == NULL, which caused a crash when called.
2112
Tim Petersecc6e6a2005-07-10 22:30:55 +00002113- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002114 fixes the crash seen in bug #1165761
2115
Raymond Hettinger96229b12005-03-11 06:49:40 +00002116- Added two new builtins, any() and all().
2117
Brett Cannon409d8f22005-03-05 06:47:57 +00002118- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002119 (e.g., ``class C(): pass`` is no longer a syntax error).
2120 Patch #1176012 added support to the 'parser' module and 'compiler' package
2121 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002122
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002123- Patch #1115086: Support PY_LONGLONG in structmember.
2124
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002125- Bug #1155938: new style classes did not check that __init__() was
2126 returning None.
2127
Tim Petersecc6e6a2005-07-10 22:30:55 +00002128- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002129 ('\') with a specific error message.
2130
Martin v. Löwisff232d72005-03-03 09:24:38 +00002131- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2132
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002133- Bug #1124295: the __name__ attribute of file objects was
2134 inadvertently made inaccessible in restricted mode.
2135
Tim Petersecc6e6a2005-07-10 22:30:55 +00002136- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002137 an ferror() call.
2138
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002139- min() and max() now support key= arguments with the same meaning as in
2140 list.sort().
2141
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002142- The peephole optimizer now performs simple constant folding in expressions:
2143 (2+3) --> (5).
2144
Raymond Hettingera422c342005-01-11 03:03:27 +00002145- set and frozenset objects can now be marshalled. SF #1098985.
2146
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002147- Bug #1077106: Poor argument checking could cause memory corruption
2148 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002149
Jeremy Hyltonab630502005-02-04 18:44:06 +00002150- The parser did not complain about future statements in illegal
2151 positions. It once again reports a syntax error if a future
2152 statement occurs after anything other than a doc string.
2153
Neil Schemenauercf52c072005-08-12 17:34:58 +00002154- Change the %s format specifier for str objects so that it returns a
2155 unicode instance if the argument is not an instance of basestring and
2156 calling __str__ on the argument returns a unicode instance.
2157
Tim Petersf4e69282006-02-27 17:15:31 +00002158- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2159 current thread state when the auto-GIL-state machinery knows about
2160 it (since the thread state is being deleted, continuing to remember it
2161 can't help, but can hurt if another thread happens to get created with
2162 the same thread id).
2163
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002164Extension Modules

2181
2182- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2183
2184- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002185 is deprecated. The undocumented re.engine variable no longer exists.

2189
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002190- The unicodedata module was updated to the 4.1 version of the Unicode
2191 database. The 3.2 version is still available as unicodedata.db_3_2_0
2192 for applications that require this specific version (such as IDNA).
2193
Neal Norwitzb62c4332006-03-04 18:35:47 +00002194- The timing module is no longer built by default. It was deprecated
2195 in PEP 4 in Python 2.0 or earlier.
2196
Guido van Rossum1968ad32006-02-25 22:38:04 +00002197- Patch 1433928: Added a new type, defaultdict, to the collections module.

2295 the request code argument, which results in more C-like behaviour
2296 for large or negative values.
2297
Tim Petersecc6e6a2005-07-10 22:30:55 +00002298- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

2340
Raymond Hettingerb2594052004-12-05 09:25:51 +00002341- itertools.islice() now accepts None for the start and step arguments.

Tim Peters112aad32006-07-19 00:03:19 +00002353
Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002354- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2355 been renamed to have only a single underscore prefix. This was done to
2356 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002357
Nick Coghlan43832302006-04-23 17:04:07 +00002358- PEP 338: new module runpy defines a run_module function to support
2359 executing modules which provide access to source code or a code object
2360 via the PEP 302 import mechanisms.
2361
Anthony Baxter93f5b932006-04-03 08:05:07 +00002362- The email module's parsedate_tz function now sets the daylight savings

2370 in attribute values.
2371
Anthony Baxterc51ee692006-04-01 00:57:31 +00002372- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002373 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002374 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002375 module will not be built.
2376
Tim Petersc17976e2006-04-01 00:26:53 +00002377- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2378 aren't officially supported here, and trying to use them will probably
2379 raise an exception some day. But dicts have been allowed, and "mostly
2380 worked", so support for them won't go away without warning.
2381
Georg Brandl338ef7d2006-03-31 18:42:16 +00002382- Bug #1445068: getpass.getpass() can now be given an explicit stream
2383 argument to specify where to write the prompt.
2384

2394 to make it easier to monitor when daemon threads have completed
2395 processing all enqueued tasks. Patch #1455676.
2396
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002397- popen2.Popen objects now preserve the command in a .cmd attribute.

2400
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002401- email 4.0 package now integrated. This is largely the same as the email 3.0
2402 package that was included in Python 2.3, except that PEP 8 module names are
2403 now used (e.g. mail.message instead of email.Message). The MIME classes
2404 have been moved to a subpackage (e.g. email.mime.text instead of
2405 email.MIMEText). The old names are still supported for now. Several
2406 deprecated Message methods have been removed and lots of bugs have been
2407 fixed. More details can be found in the email package documentation.
2408
Walter Dörwald40108c92006-03-27 08:15:44 +00002409- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2410 (a subclass of tuple) that provides incremental decoders and encoders
2411 (a way to use stateful codecs without the stream API). Python functions
2412 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2413 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2414 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002415
Walter Dörwald067db482006-03-15 22:17:27 +00002416- Patch #1359365: Calling next() on a closed StringIO.String object raises
2417 a ValueError instead of a StopIteration now (like file and cString.String do).
2418 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2419 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002420
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002421- A regrtest option -w was added to re-run failed tests in verbose mode.

Martin v. Löwis3e865952006-01-24 15:51:21 +00002469 specifications, raises IOErrors when proxies for unsupported protocols
2470 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00002493 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2494 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2495 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2496 Ronald L. Rivest offered this advice for Python:
2497
2498 "The consensus of researchers in this area (at least as
2499 expressed at the NIST Hash Function Workshop 10/31/05),
2500 is that SHA-256 is a good choice for the time being, but
2501 that research should continue, and other alternatives may
2502 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002503
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002504- Added a subset of Fredrik Lundh's ElementTree package. Available

2581 to W3C name (404 -> 'Not Found'). RFE #1216944.
2582
Georg Brandl9e43acf2005-07-04 17:16:07 +00002583- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2584 as this can cause problems with apps closing all file descriptors.
2585
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002586- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002587 it can be missing in embedded interpreters
Georg Brandl5284b532005-06-26 22:54:58 +00002588

2590
Georg Brandlfbff1bc2005-06-26 21:36:25 +00002591- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
2592 error messages.
2593
Georg Brandl379f99d2005-06-26 21:09:38 +00002594- Bug #1108948: Cookie.py produced invalid JavaScript code.
2595
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00002596- The tokenize module now detects and reports indentation errors.
2597 Bug #1224621.
2598
Raymond Hettinger68c04532005-06-10 11:05:19 +00002599- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002600 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002601 the generate_tokens() function now accepts a callable argument that
2602 terminates by raising StopIteration.
2603
Georg Brandl9166e1a2005-06-04 09:20:03 +00002604- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2605
Georg Brandl268e61c2005-06-03 14:28:50 +00002606- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2607 component of the path.
2608
Skip Montanaro174dd222005-05-14 20:54:16 +00002609- Patch #1120353: The xmlrpclib module provides better, more transparent,
2610 support for datetime.{datetime,date,time} objects. With use_datetime set
2611 to True, applications shouldn't have to fiddle with the DateTime wrapper
2612 class at all.
2613
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002614- distutils.commands.upload was added to support uploading distribution
2615 files to PyPI.
2616
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002617- distutils.commands.register now encodes the data as UTF-8 before posting
2618 them to PyPI.
2619
Raymond Hettinger267b8682005-03-27 10:47:39 +00002620- decimal operator and comparison methods now return NotImplemented
2621 instead of raising a TypeError when interacting with other types. This
2622 allows other classes to implement __radd__ style methods and have them
2623 work as expected.
2624
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002625- Bug #1163325: Decimal infinities failed to hash. Attempting to
2626 hash a NaN raised an InvalidOperation instead of a TypeError.
2627
Tim Petersecc6e6a2005-07-10 22:30:55 +00002628- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002629 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2630

2662
Guido van Rossumd0641422005-02-03 15:01:24 +00002663- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2664 disables recursive traversal through instance attributes, which can
2665 be exploited in various ways.
2666
Tim Peterse3547fd2005-12-16 23:13:57 +00002667- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002668 flags on the HTTP listening socket.
2669
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002670- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2671 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2672
Fred Drakefbdeaad2006-07-29 16:56:15 +00002673- Patches #893642, #1039083: add allow_none, encoding arguments to
2674 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002675
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002676- Bug #1110478: Revert os.environ.update to do putenv again.

Thomas Hellerd6c6e222005-01-20 19:20:16 +00002678- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2679
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002680- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2681
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002682- Enhancements to the csv module:
2683
2684 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002685 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002686 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002687 + Dialect parameter parsing has been re-implemented to improve error
2688 reporting.
2689 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2690 dictates.
2691 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002692 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002693 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002694 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2695 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002696 + reader now allows \r characters to be quoted (previously it only allowed
2697 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002698 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002699 + Dialect classes passed to the module are no longer instantiated by
2700 the module before being parsed (the former validation scheme required
2701 this, but the mechanism was unreliable).
2702 + The dialect registry now contains instances of the internal
2703 C-coded dialect type, rather than references to python objects.
2704 + the internal c-coded dialect type is now immutable.
2705 + register_dialect now accepts the same keyword dialect specifications
2706 as the reader and writer, allowing the user to register dialects
2707 without first creating a dialect class.
2708 + a configurable limit to the size of parsed fields has been added -
2709 previously, an unmatched quote character could result in the entire
2710 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002711 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002712 the parser field size limit (returning the former limit). The initial
2713 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002714 + A line_num attribute has been added to the reader object, which tracks
2715 the number of lines read from the source iterator. This is not
2716 the same as the number of records returned, as records can span
2717 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002718 + reader and writer objects were not being registered with the cyclic-GC.
2719 This has been fixed.
2720
Brett Cannone6539c42005-01-08 02:43:53 +00002721- _DummyThread objects in the threading module now delete self.__block that is
2722 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2723 lock primitives tend to be limited in number and thus should not be wasted on
2724 a _DummyThread object. Fixes bug #1089632.
2725
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002726- The imghdr module now detects Exif files.
2727
Raymond Hettinger6065d322004-12-20 23:51:53 +00002728- StringIO.truncate() now correctly adjusts the size attribute.
2729 (Bug #951915).
2730
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002731- locale.py now uses an updated locale alias table (built using
2732 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2733 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002734 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002735
Raymond Hettinger3557f422004-12-07 12:02:02 +00002736- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2737
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002738- the pickle module no longer accepts the deprecated None option in the
2739 args tuple returned by __reduce__().
2740
Brett Cannon84667c02004-12-07 03:25:18 +00002741- optparse now optionally imports gettext. This allows its use in setup.py.
2742
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002743- the pickle module no longer uses the deprecated bin parameter.
2744
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002745- the shelve module no longer uses the deprecated binary parameter.
2746
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002747- the pstats module no longer uses the deprecated ignore() method.
2748
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002749- the filecmp module no longer uses the deprecated use_statcache argument.
2750
Raymond Hettinger664347b2004-12-04 21:21:53 +00002751- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2752 extended or overridden by subclasses. Formerly, the subclassed method would
2753 be ignored by the rest of the module. (Bug #1078905).
2754
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002755- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002756 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002757
Walter Dörwald36733692004-12-22 12:50:50 +00002758- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2759 once when a size argument is given. This prevents a buffer overflow in the
2760 tokenizer with very long source lines.
2761
Barry Warsaw538561e2006-01-01 21:48:54 +00002762- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2763 immediately after creating the object, without any intervening
2764 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002765
Skip Montanaro05885812005-01-16 20:48:27 +00002766- The reconvert.quote function can now emit triple-quoted strings. The
2767 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002768
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002769- ``UserString.MutableString`` now supports negative indices in
2770 ``__setitem__`` and ``__delitem__``
2771
Greg Ward40407942005-03-05 02:53:17 +00002772- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2773 correctly.
2774
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002775- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2776 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2777 character even if the user has passed a size parameter to get a proper
2778 line ending. Remove the special handling of a "\r\n" that has been split
2779 between two lines.
2780
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002781- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2782 about illegal code points. The codec now supports PEP 293 style error
2783 handlers.
2784
Walter Dörwald78a78b02005-09-01 12:04:29 +00002785- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002786 from the input stream, so that the output is a byte string in the correct
2787 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002788
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002789- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2790 considering it exactly like a '*'.
2791
Walter Dörwald007f8df2005-10-09 19:42:27 +00002792- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2793 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002794
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002795- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2796
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002797- Patch #1413711: Certain patterns of differences were making difflib
2798 touch the recursion limit.
2799
Walter Dörwald58917a62006-03-31 15:26:22 +00002800- Bug #947906: An object oriented interface has been added to the calendar
2801 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002802 called as a script (e.g. via ``python -mcalendar``). Localized month and
2803 weekday names can be ouput (even if an exotic encoding is used) using
2804 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002805

2829 vulnerability in zlib 1.2.1 and 1.2.2.
2830
Brett Cannon08cd5982005-04-24 22:26:38 +00002831- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2832 flags that change binary compatibility. Changes were also made to
2833 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002834 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002835

Martin v. Löwise2713be2005-03-08 15:03:08 +00002840- Bug #1158607: Build with --disable-unicode again.
2841
Brett Cannon46d96232005-02-16 00:07:19 +00002842- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2843 defined. Discovered as a result of not being able to build on OS X.
2844
Brett Cannon516592f2004-12-07 00:42:59 +00002845- setup.py now uses the directories specified in LDFLAGS using the -L option
2846 and in CPPFLAGS using the -I option for adding library and include
2847 directories, respectively, for compiling extension modules against. This has
2848 led to the core being compiled using the values in CPPFLAGS. It also removes
2849 the need for the special-casing of both DarwinPorts and Fink for darwin since
2850 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2851 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2852 Fink, ``-I/opt/local/include`` for DarwinPorts).
2853
Brett Cannon43802422005-02-10 20:48:03 +00002854- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2855 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2856 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2857 Closes bug #1096244. Thanks Gregory Bond.

2860-----
2861
Tim Petersc9d78aa2006-03-26 23:27:58 +00002862- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2863 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2864 is obtained via the ``PyObject_`` family, it must be released via the
2865 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2866 always been officially true, but when Python's small-object allocator was
2867 introduced, an attempt was made to cater to a few extension modules
2868 discovered at the time that obtained memory via ``PyObject_New`` but
2869 released it via ``PyMem_DEL``. It's years later, and if such code still
2870 exists it will fail now (probably with segfaults, but calling wrong
2871 low-level memory management functions can yield many symptoms).
2872
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002873- Added a C API for set and frozenset objects.
2874
Raymond Hettinger66517482004-12-03 11:45:13 +00002875- Removed PyRange_New().
2876
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002877- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2878 mapping argument now. This string is used as a mapping table. Byte values
2879 greater than the length of the string and 0xFFFE are treated as undefined
2880 mappings.

Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002888- Patch #1276356: New resource "urlfetch" is implemented. This enables
2889 even impatient people to run tests that require remote files.
