Andrew M. Kuchling830358a2006-11-17 16:16:28 +0000622- mailbox.py: Change MH.pack() to not lock individual message files; this

Georg Brandl1f215782006-09-24 10:36:08 +0000641- Make webbrowser.BackgroundBrowser usable in Windows (it wasn't because

725
Brett Cannon19d76c52006-09-09 07:18:44 +0000726- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This

867- Fix concatenation (+=) of long strings.
868
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000869- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000870 compared equal or unequal to a string and a UnicodeDecodeError
871 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000872
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000873 Instead, the equal (==) and unequal (!=) comparison operators will
874 now issue a UnicodeWarning and interpret the two objects as
875 unequal. The UnicodeWarning can be filtered as desired using
876 the warning framework, e.g. silenced completely, turned into an
877 exception, logged, etc.
878
879 Note that compare operators other than equal and unequal will still
880 raise UnicodeDecodeError exceptions as they've always done.

888 classic classes.
889
890- Patch #1538606, Fix __index__() clipping. There were some problems
891 discovered with the API and how integers that didn't fit into Py_ssize_t
892 were handled. This patch attempts to provide enough alternatives
893 to effectively use __index__.
894
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000895- Bug #1536021: __hash__ may now return long int; the final hash
896 value is obtained by invoking hash on the long int.
897
Thomas Hellerab1049c2006-08-08 17:37:00 +0000898- Bug #1536786: buffer comparison could emit a RuntimeWarning.
899
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000900- Bug #1535165: fixed a segfault in input() and raw_input() when
901 sys.stdin is closed.
902
Thomas Heller74d36f02006-08-04 18:17:40 +0000903- On Windows, the PyErr_Warn function is now exported from
904 the Python dll again.
905
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000906- Bug #1191458: tracing over for loops now produces a line event
907 on each iteration. Fixing this problem required changing the .pyc
908 magic number. This means that .pyc files generated before 2.5c1
909 will be regenerated.
910
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000911- Bug #1333982: string/number constants were inappropriately stored
912 in the byte code and co_consts even if they were not used, ie
913 immediately popped off the stack.
914
Georg Brandle9462c72006-08-04 18:03:37 +0000915- Fixed a reference-counting problem in property().

918Library
919-------
920
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000921- Fix a bug in the ``compiler`` package that caused invalid code to be
922 generated for generator expressions.
923
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000924- The distutils version has been changed to 2.5.0. The change to
925 keep it programmatically in sync with the Python version running
926 the code (introduced in 2.5b3) has been reverted. It will continue
927 to be maintained manually as static string literal.
928
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000929- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000930 and this cannot be converted to the required C type, an exception is
931 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000932 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000933
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000934- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000935 an exception.
936
Tim Peterscbdd3502006-09-05 01:47:53 +0000937- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000938 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000939 workarounds for clocks with low resolution, to stop the code yielding
940 duplicate UUIDs.
941
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000942- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
943 before raising SystemExit, allowing IDLE to honor quit() and exit().
944
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000945- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
946
Georg Brandl7a1af772006-08-14 21:55:28 +0000947- Patch #1536071: trace.py should now find the full module name of a
948 file correctly even on Windows.
949
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000950- logging's atexit hook now runs even if the rest of the module has
951 already been cleaned up.
952
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000953- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000954
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000955- Bug #1531405, format_exception no longer raises an exception if
956 str(exception) raised an exception.
957
Neil Schemenauer06ded092006-08-04 16:20:30 +0000958- Fix a bug in the ``compiler`` package that caused invalid code to be
959 generated for nested functions.

970 raises the correct exceptions.
971
Thomas Heller1ce433e2006-08-14 16:20:04 +0000972- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
973 '-no-stack-protector' compiler flag for OpenBSD has been removed.
974
Thomas Heller86720042006-08-14 11:17:48 +0000975- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
976 uses the _as_parameter_ attribute when objects are passed to foreign
977 function calls. The ctypes version number was changed to 1.0.1.
978
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000979- Bug #1530559, struct.pack raises TypeError where it used to convert.
980 Passing float arguments to struct.pack when integers are expected
981 now triggers a DeprecationWarning.
982
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000983

1005-----
1006
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +00001007- Bug #1535502, build _hashlib on Windows, and use masm assembler
1008 code in OpenSSL.
1009
Thomas Hellerdb7b4432006-08-04 19:49:31 +00001010- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

Tim Peters4643c2f2006-08-10 22:45:34 +00001015C API
1016-----
1017
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001018- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1019
Tim Peters4643c2f2006-08-10 22:45:34 +00001020- Bug #1069160. Internal correctness changes were made to
1021 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1022 the documentation was changed to state that the return value
1023 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001026What's New in Python 2.5 beta 3?
1027================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001028
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001029*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001030
1031Core and builtins
1032-----------------
1033
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001034- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001035 returned a long (see PEP 353).
1036
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001037- Bug #1515471: string.replace() accepts character buffers again.
1038
Neal Norwitz07aadb12006-07-30 06:55:48 +00001039- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1040 This provides the proper warning for struct.pack().
1041 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1042
Neal Norwitz0d62a062006-07-30 06:53:31 +00001043- Patch #1531113: Fix augmented assignment with yield expressions.
1044 Also fix a SystemError when trying to assign to yield expressions.
1045
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001046- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1047 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1048 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1049 excessive filesystem operations during imports.
1050
Tim Petersbc24eee2006-07-27 01:14:53 +00001051- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1052 operations on signed longs that are formally undefined by C.
1053 Unfortunately, at least one compiler now cares about that, so complicated
1054 the code to make that compiler happy again.
1055
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001056- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1057
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001058- Patch #1232023: Stop including current directory in search
1059 path on Windows.
1060
Neal Norwitze1fdb322006-07-21 05:32:28 +00001061- Fix some potential crashes found with failmalloc.
1062
Neal Norwitze7563102006-07-17 01:00:16 +00001063- Fix warnings reported by Klocwork's static analysis tool.
1064
Neal Norwitz84be93b2006-07-16 01:50:38 +00001065- Bug #1512814, Fix incorrect lineno's when code within a function
1066 had more than 255 blank lines.
1067
Georg Brandl9dceedb2006-07-12 15:31:17 +00001068- Patch #1521179: Python now accepts the standard options ``--help`` and
1069 ``--version`` as well as ``/?`` on Windows.
1070
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001071- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001072 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001073 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001074
Tim Peters112aad32006-07-19 00:03:19 +00001075- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001076 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001077 new ``sys._current_frames()`` returns a dictionary with one entry,
1078 mapping the faux "thread id" 0 to the current frame.
1079
Ronald Oussoren3075e162006-07-25 20:28:55 +00001080- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001081
Ronald Oussoren3075e162006-07-25 20:28:55 +00001082
Neal Norwitza1f10902006-07-12 07:28:29 +00001083Library
1084-------
1085
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001086- Correction of patch #1455898: In the mbcs decoder, set final=False
1087 for stream decoder, but final=True for the decode function.
1088
Georg Brandl07fec3a2006-08-01 18:49:24 +00001089- os.urandom no longer masks unrelated exceptions like SystemExit or
1090 KeyboardInterrupt.
1091
Tim Peters4643c2f2006-08-10 22:45:34 +00001092- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001093 shutil.copytree on Windows
1094
Georg Brandle34ac7c2006-07-30 11:07:23 +00001095- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1096 refers to file descriptors, not file objects.
1097
Tim Peterscbdd3502006-09-05 01:47:53 +00001098- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001099 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001100 #1513611, and probably others.
1101
Georg Brandledd9b0d2006-07-29 09:33:26 +00001102- Bug #1441397: The compiler module now recognizes module and function
1103 docstrings correctly as it did in Python 2.4.
1104
Tim Peters6f681472006-07-27 23:44:37 +00001105- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1106 lost that tests are sorted by name before being run. This rarely
1107 matters for well-written tests, but can create baffling symptoms if
1108 side effects from one test to the next affect outcomes. ``DocTestFinder``
1109 has been changed to sort the list of tests it returns.
1110
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001111- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001112 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001113
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001114- Bug #978833: Really close underlying socket in _socketobject.close.
1115
Georg Brandldb232dc2006-08-20 13:15:43 +00001116- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1117 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001118
Georg Brandlcf0c1722006-07-26 07:23:32 +00001119- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1120 to recursive calls and call it with the failing package name.
1121
Martin v. Löwis0b483032006-07-25 09:53:12 +00001122- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1123
Georg Brandlc13c34c2006-07-24 14:09:56 +00001124- Patch #1515343: Fix printing of deprecated string exceptions with a
1125 value in the traceback module.
1126
Greg Ward48fae7a2006-07-23 16:05:51 +00001127- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1128
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001129- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1130
Brett Cannoncaebe222006-07-18 04:41:36 +00001131- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1132 argument tuple. For arguments where zero is illegal, the value is forced to
1133 the minimum value that is correct. This is to support an undocumented but
1134 common way people used to fill in inconsequential information in the time
1135 tuple pre-2.4.
1136
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001137- Patch #1220874: Update the binhex module for Mach-O.
1138
Barry Warsawb110bad2006-07-21 14:51:07 +00001139- The email package has improved RFC 2231 support, specifically for
1140 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1141 (name*0=<blah>) parameter continuations. This may change the types of
1142 values returned from email.message.Message.get_param() and friends.
1143 Specifically in some cases where non-encoded continuations were used,
1144 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1145 will just return the string (since non-encoded continuations don't have
1146 charset and language parts).
1147
1148 Also, whereas % values were decoded in all parameter continuations, they are
1149 now only decoded in encoded parameter parts.
1150
Ronald Oussoren3075e162006-07-25 20:28:55 +00001151- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1152
1153- Bug #1517996: IDLE now longer shows the default Tk menu when a
1154 path browser, class browser or debugger is the frontmost window on MacOS X
1155
Barry Warsaw00decd72006-07-27 23:43:15 +00001156- Patch #1520294: Support for getset and member descriptors in types.py,
1157 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1158 of an object against these built-in types and more importantly, for getting
1159 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001162Extension Modules
1163-----------------
1164
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001165- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1166 a socket operation on a socket with a timeout, the exception will be
1167 caught correctly. Previously, the exception was not caught.
1168
Thomas Heller1393d6a2006-07-28 21:43:20 +00001169- Patch #1529514: The _ctypes extension is now compiled on more
1170 openbsd target platforms.
1171
Tim Peters9cab5932006-07-28 00:30:00 +00001172- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1173 a memory leak, affecting pickles and deep copies.
1174
Tim Petersbc24eee2006-07-27 01:14:53 +00001175- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001176 Paul Eggert.
1177
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001178- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1179
Thomas Hellerce049a02006-07-14 17:51:14 +00001180- Patch #1521817: Index range checking on ctypes arrays containing
1181 exactly one element enabled again. This allows iterating over these
1182 arrays, without the need to check the array size before.
1183
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001184- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001185 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001186 /dev/null in certain cases; this is now fixed.
1187
Thomas Heller47d7a062006-07-12 08:43:47 +00001188- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1189 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001190
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001191- Because of a misspelled preprocessor symbol, ctypes was always
1192 compiled without thread support; this is now fixed.
1193
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001194- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1195 methods now allow their database parameter to be None as the
1196 sleepycat API allows.
1197
Matt Flemingec926502006-07-28 11:27:27 +00001198- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1199 bluetooth API compared with Linux and FreeBSD.
1200
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001201Tests
1202-----
1203
1204- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1205 how long the test file should take to play. Now accepts taking 2.93 secs
1206 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1207
Georg Brandl4793aa32006-07-28 18:31:39 +00001208- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1209 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1210 run via ``regrtest.py``. Now they do.

1214
1215- Bug #1439538: Drop usage of test -e in configure as it is not portable.
1216
Ronald Oussoren26cad082006-08-01 21:00:57 +00001217Mac
1218---
1219
1220- PythonLauncher now works correctly when the path to the script contains
1221 characters that are treated specially by the shell (such as quotes).
1222
1223- Bug #1527397: PythonLauncher now launches scripts with the working directory
1224 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001225 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001226 expect.

1234Core and builtins
1235-----------------
1236
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001237- Bug #1441486: The literal representation of -(sys.maxint - 1)
1238 again evaluates to a int object, not a long.
1239
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001240- Bug #1501934: The scope of global variables that are locally assigned
1241 using augmented assignment is now correctly determined.
1242
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001243- Bug #927248: Recursive method-wrapper objects can now safely
1244 be released.
1245
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001246- Bug #1417699: Reject locale-specific decimal point in float()
1247 and atof().
1248
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001249- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1250 omit a default "error" argument for NULL pointer. This allows
1251 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001252
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001253- Bug #1519018: 'as' is now validated properly in import statements.
1254
Neal Norwitz28746ab2006-07-09 22:14:42 +00001255- On 64 bit systems, int literals that use less than 64 bits are
1256 now ints rather than longs.
1257
Neal Norwitzed657552006-07-10 00:04:44 +00001258- Bug #1512814, Fix incorrect lineno's when code at module scope
1259 started after line 256.
1260
Tim Peters32a83612006-07-10 21:08:24 +00001261- New function ``sys._current_frames()`` returns a dict mapping thread
1262 id to topmost thread stack frame. This is for expert use, and is
1263 especially useful for debugging application deadlocks. The functionality
1264 was previously available in Fazal Majid's ``threadframe`` extension
1265 module, but it wasn't possible to do this in a wholly threadsafe way from
1266 an extension.
1267

1272 VS 2003.
1273
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001274- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1275
Tim Peters32a83612006-07-10 21:08:24 +00001276- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001277 environment variable to be set in order to the SDK environment
1278 for finding the compiler, include files, etc.

1281
Nick Coghlan2d792252006-07-06 13:47:18 +00001282- warnings.py now ignores ImportWarning by default
1283
Thomas Woutersadd19112006-07-05 11:03:49 +00001284- string.Template() now correctly handles tuple-values. Previously,
1285 multi-value tuples would raise an exception and single-value tuples would
1286 be treated as the value they contain, instead.
1287
Martin v. Löwisede77f52006-07-03 13:01:35 +00001288- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1290
Martin v. Löwis45482392006-07-03 12:28:58 +00001291- Bug #1267547: Put proper recursive setup.py call into the
1292 spec file generated by bdist_rpm.
1293
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001294- Bug #1514693: Update turtle's heading when switching between
1295 degrees and radians.
1296
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001297- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001298 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001299
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001300- Bug #1514703: Only setup canvas window in turtle when the canvas
1301 is created.
1302
Martin v. Löwis7596e832006-07-01 15:33:37 +00001303- Bug #1513223: .close() of a _socketobj now releases the underlying
1304 socket again, which then gets closed as it becomes unreferenced.

1307 attribute values.
1308
1309- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1310 sgmllib ('[' and ']' were not accepted).
1311
Georg Brandl1be63af2006-06-28 20:23:25 +00001312- Fix a bug in the turtle module's end_fill function.
1313
Brett Cannon53ab5b72006-06-22 16:49:14 +00001314- Bug #1510580: The 'warnings' module improperly required that a Warning
1315 category be either a types.ClassType and a subclass of Warning. The proper
1316 check is just that it is a subclass with Warning as the documentation states.
1317
Georg Brandlad29e632006-06-21 17:45:17 +00001318- The compiler module now correctly compiles the new try-except-finally
1319 statement (bug #1509132).
1320
Neal Norwitz60373cd2006-06-22 06:30:50 +00001321- The wsgiref package is now installed properly on Unix.
1322
Vinay Sajip28e57612006-07-01 10:45:20 +00001323- A bug was fixed in logging.config.fileConfig() which caused a crash on
1324 shutdown when fileConfig() was called multiple times.
1325
Gerhard Häring762fbd32006-07-02 17:48:30 +00001326- The sqlite3 module did cut off data from the SQLite database at the first
1327 null character before sending it to a custom converter. This has been fixed
1328 now.
1329
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001330Extension Modules
1331-----------------
1332
Tim Peters112aad32006-07-19 00:03:19 +00001333- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1334 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1335 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001336
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001337- Assigning None to pointer type fields in ctypes structures possible
1338 overwrote the wrong fields, this is fixed now.
1339
1340- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1341 on non-Windows platforms.
1342
1343- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1344 integer or long, without range checking.
1345
1346- Patch #1517790: It is now possible to use custom objects in the ctypes
1347 foreign function argtypes sequence as long as they provide a from_param
1348 method, no longer is it required that the object is a ctypes type.
1349
1350- The '_ctypes' extension module now works when Python is configured
1351 with the --without-threads option.
1352
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001353- Bug #1513646: os.access on Windows now correctly determines write
1354 access, again.
1355
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001356- Bug #1512695: cPickle.loads could crash if it was interrupted with
1357 a KeyboardInterrupt.
1358
Neal Norwitza12aa882006-07-06 06:45:08 +00001359- Bug #1296433: parsing XML with a non-default encoding and
1360 a CharacterDataHandler could crash the interpreter in pyexpat.
1361
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001362- Patch #1516912: improve Modules support for OpenVMS.
1363
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001364Build
1365-----
1366
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001367- Automate Windows build process for the Win64 SSL module.
1368
Tim Peters32a83612006-07-10 21:08:24 +00001369- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001370 Previously, the slight difference could cause compilation errors of the
1371 'zlib' module on systems with more than one version of zlib.
1372
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001373- The MSI compileall step was fixed to also support a TARGETDIR
1374 with spaces in it.
1375
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001376- Bug #1517388: sqlite3.dll is now installed on Windows independent

1385- Call os.waitpid() at the end of tests that spawn child processes in order
1386 to minimize resources (zombies).
1387
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001388Documentation
1389-------------
1390
Nick Coghlan2d792252006-07-06 13:47:18 +00001391- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1392 documentation for the warnings module.
1393
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001394- Patch #1509163: MS Toolkit Compiler no longer available.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001403
1404Core and builtins
1405-----------------
1406
Georg Brandla56b9152006-06-19 06:35:54 +00001407- Patch #1507676: Error messages returned by invalid abstract object operations
1408 (such as iterating over an integer) have been improved and now include the
1409 type of the offending object to help with debugging.
1410
Brett Cannonea3912b2006-06-13 21:46:41 +00001411- Bug #992017: A classic class that defined a __coerce__() method that returned
1412 its arguments swapped would infinitely recurse and segfault the interpreter.
1413
Neal Norwitz909eb122006-06-12 02:13:21 +00001414- Fix the socket tests so they can be run concurrently.
1415
Neal Norwitzb9845e72006-06-12 02:11:18 +00001416- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001417 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001418
Brett Cannon22565aa2006-06-09 22:31:23 +00001419- Bug #532646: object.__call__() will continue looking for the __call__
1420 attribute on objects until one without one is found. This leads to recursion
1421 when you take a class and set its __call__ attribute to an instance of the
1422 class. Originally fixed for classic classes, but this fix is for new-style.
1423 Removes the infinite_rec_3 crasher.
1424
Georg Brandl24250812006-06-09 18:45:48 +00001425- The string and unicode methods startswith() and endswith() now accept
1426 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1427
Brett Cannonde3b0522006-06-08 17:00:45 +00001428- Buffer objects, at the C level, never used the char buffer
1429 implementation even when the char buffer for the wrapped object was
1430 explicitly requested (originally returned the read or write buffer).
1431 Now a TypeError is raised if the char buffer is not present but is
1432 requested.
1433
Georg Brandlddbaa662006-06-04 21:56:52 +00001434- Patch #1346214: Statements like "if 0: suite" are now again optimized
1435 away like they were in Python 2.4.
1436
Georg Brandlb7c8f542006-05-27 12:30:25 +00001437- Builtin exceptions are now full-blown new-style classes instead of
1438 instances pretending to be classes, which speeds up exception handling
1439 by about 80% in comparison to 2.5a2.
1440
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001441- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1442 Unicode 4.1.
1443
Georg Brandlf4ef1162006-05-26 18:03:31 +00001444- Patch #921466: sys.path_importer_cache is now used to cache valid and
1445 invalid file paths for the built-in import machinery which leads to
1446 fewer open calls on startup.
1447
Tim Peters696cf432006-05-24 21:10:40 +00001448- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1449 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1450 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1451 the number of input digits (it was and remains linear-time for bases
1452 2, 4, 8, 16 and 32).
1453
Tim Petersb713ec22006-05-23 18:45:30 +00001454- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1455 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1456 an integer close to ``sys.maxint``. This was repaired by patch
1457 #1335972, which also gives a nice speedup.
1458
Richard Jonescebbefc2006-05-23 18:28:17 +00001459- Patch #1337051: reduced size of frame objects.
1460
1461- PyErr_NewException now accepts a tuple of base classes as its
1462 "base" parameter.
1463
Richard Jones7c88dcc2006-05-23 10:37:38 +00001464- Patch #876206: function call speedup by retaining allocated frame
1465 objects.
1466
Georg Brandl7b90e162006-05-18 07:01:27 +00001467- Bug #1462152: file() now checks more thoroughly for invalid mode
1468 strings and removes a possible "U" before passing the mode to the
1469 C library function.
1470
Neal Norwitz1004a532006-05-15 07:17:23 +00001471- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1472
Neal Norwitz373f0a72006-05-15 07:04:36 +00001473- Bug #1487966: Fix SystemError with conditional expression in assignment
1474
Martin v. Löwis879768d2006-05-11 13:28:43 +00001475- WindowsError now has two error code attributes: errno, which carries
1476 the error values from errno.h, and winerror, which carries the error
1477 values from winerror.h. Previous versions put the winerror.h values
1478 (from GetLastError()) into the errno attribute.
1479
Martin v. Löwis77736712006-05-04 05:51:03 +00001480- Patch #1475845: Raise IndentationError for unexpected indent.
1481
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001482- Patch #1479181: split open() and file() from being aliases for each other.
1483
Tim Peters44bd9862006-06-01 13:49:23 +00001484- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1485 methods were always silently ignored by dictionaries when comparing keys.
1486 They are now passed through (except when using the C API function
1487 ``PyDict_GetItem()``, whose semantics did not change).
1488
1489- Bug #1456209: In some obscure cases it was possible for a class with a
1490 custom ``__eq__()`` method to confuse dict internals when class instances
1491 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1492 No, you don't have any code that did this ;-)

1496
Trent Mick960a3f82006-06-28 20:30:41 +00001497- Bug #1295808: expat symbols should be namespaced in pyexpat
1498
1499- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1500
Brett Cannon6ee7d012006-06-08 16:23:04 +00001501- Change binascii.hexlify to accept a read-only buffer instead of only a char
1502 buffer and actually follow its documentation.
1503
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001504- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1505
Nick Coghlanc649ec52006-05-29 12:43:05 +00001506- Patch #1478788 (modified version): The functional extension module has
1507 been renamed to _functools and a functools Python wrapper module added.
1508 This provides a home for additional function related utilities that are
1509 not specifically about functional programming. See PEP 309.
1510
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001511- Patch #1493701: performance enhancements for struct module.
1512
Georg Brandl378d5922006-05-17 14:26:50 +00001513- Patch #1490224: time.altzone is now set correctly on Cygwin.
1514
Georg Brandl8d3342b2006-05-16 07:38:27 +00001515- Patch #1435422: zlib's compress and decompress objects now have a
1516 copy() method.
1517
Andrew MacIntyre92913322006-06-13 15:04:24 +00001518- Patch #1454481: thread stack size is now tunable at runtime for thread
1519 enabled builds on Windows and systems with Posix threads support.
1520
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001521- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1522 (up to the system limit of 32K characters).
1523
1524- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1525 As a result, these functions now raise WindowsError instead of OSError.
1526
Tim Peters7a822da2006-05-25 21:50:17 +00001527- ``time.clock()`` on Win64 should use the high-performance Windows
1528 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1529 Windows platforms).
1530
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001531- Calling Tk_Init twice is refused if the first call failed as that
1532 may deadlock.
1533
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001534- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1535 accept it without potentially using an uninitialized pointer.
1536
1537- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1538 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1539 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001540
Gregory P. Smith372b5832006-06-05 18:48:21 +00001541- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001542 [pybsddb project SF patch number 1466734]
1543
Gregory P. Smith372b5832006-06-05 18:48:21 +00001544- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1545 parameter is supplied. [SF pybsddb bug #1477863]
1546
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001547- bsddb: the __len__ method of a DB object has been fixed to return correct
1548 results. It could previously incorrectly return 0 in some cases.
1549 Fixes SF bug 1493322 (pybsddb bug 1184012).
1550
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001551- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1552 aborts the db transaction safely when a modifier callback fails.
1553 Fixes SF python patch/bug #1408584.
1554
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001555- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001556 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001557 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1558 database calls that would previously deadlock. [SF python bug #775414]
1559
Vinay Sajip28e57612006-07-01 10:45:20 +00001560- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001561
Walter Dörwald4994d952006-06-19 08:07:50 +00001562- Patch #1506645: add Python wrappers for the curses functions
1563 is_term_resized, resize_term and resizeterm.

Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001568- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1569 functions.
1570
Martin v. Löwis3798da02006-06-17 18:44:27 +00001571- Patch #812986: Update turtle output even if not tracing.

Vinay Sajip28e57612006-07-01 10:45:20 +00001573- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001574 Tkinter.BaseWidget.
1575
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001576- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.

Martin v. Löwis337487e2006-06-17 09:15:14 +00001578- Patch #763580: Add name and value arguments to Tkinter variable
1579 classes.
1580
Georg Brandl83cc0d02006-06-14 08:50:03 +00001581- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1582 mime.types file for determining MIME types.
1583
Georg Brandl2605ca82006-06-14 06:08:31 +00001584- Bug #1339007: Shelf objects now don't raise an exception in their
1585 __del__ method when initialization failed.
1586
Martin v. Löwisd8251432006-06-14 05:21:04 +00001587- Patch #1455898: The MBCS codec now supports the incremental mode for
1588 double-byte encodings.
1589
Tim Peters43898b42006-06-14 04:09:25 +00001590- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1591 guarantee that adjacent triples in the return list always describe
1592 non-adjacent blocks. Previously, a pair of matching blocks could end
1593 up being described by multiple adjacent triples that formed a partition
1594 of the matching pair.
1595
Greg Ward0e0c9f42006-06-11 16:24:11 +00001596- Bug #1498146: fix optparse to handle Unicode strings in option help,
1597 description, and epilog.
1598
Greg Wardd1c797e2006-06-11 14:42:41 +00001599- Bug #1366250: minor optparse documentation error.
1600
Greg Ward7f547402006-06-11 00:40:49 +00001601- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1602 clarify docs.
1603
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001604- The wsgiref package has been added to the standard library.
1605
Nick Coghlan676725d2006-06-08 13:54:49 +00001606- The functions update_wrapper() and wraps() have been added to the functools
1607 module. These make it easier to copy relevant metadata from the original
1608 function when writing wrapper functions.
1609
Tim Petersd6a9eef2006-06-05 01:48:21 +00001610- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1611 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001612
Martin v. Löwis3f767792006-06-04 19:36:28 +00001613- Patch #1359618: Speed up charmap encoder by using a trie structure
1614 for lookup.
1615
Tim Petersd609b1a2006-06-02 23:22:51 +00001616- The functions in the ``pprint`` module now sort dictionaries by key
1617 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1618 if and only if its display required more than one line, although that
1619 wasn't documented. The new behavior increases predictability; e.g.,
1620 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1621
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001622- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1623 (thanks for J. J. Lee).
1624
Georg Brandl2b330372006-05-28 20:23:12 +00001625- Patch #1496206: improve urllib2 handling of passwords with respect to
1626 default HTTP and HTTPS ports.
1627
George Yoshidaf3c65de2006-05-28 16:39:09 +00001628- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1629
Bob Ippolito7298f272006-05-23 18:43:47 +00001630- Patch #1281707: speed up gzip.readline.
1631
Georg Brandlb89316f2006-05-17 15:51:16 +00001632- Patch #1180296: Two new functions were added to the locale module:
1633 format_string() to get the effect of "format % items" but locale-aware,
1634 and currency() to format a monetary number with currency sign.
1635
Georg Brandle3a25832006-05-17 14:56:04 +00001636- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1637 and several features added, such as speed and geometry control.
1638
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001639- Patch #1488881: add support for external file objects in bz2 compressed
1640 tarfiles.
1641
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001642- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1643 stdout arguments, making it possible to redirect input and output
1644 for remote debugging.
1645
1646- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1647 a couple of issues, notably handling of long file names using the
1648 GNU LONGNAME extension.
1649
1650- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1651 new flag when ``name`` is already the name of an option flag.
1652
1653- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1654 package.
1655
1656- Patch #1472854: make the rlcompleter.Completer class usable on non-
1657 UNIX platforms.
1658
1659- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1660
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001661- Bug #1472827: correctly escape newlines and tabs in attribute values in

1698-----------------
1699
Thomas Heller1b046642006-04-18 18:51:06 +00001700- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1701 by converting these apis from macros into exported functions again:
1702
1703 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1704 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1705 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1706 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1707 PyRun_String Py_CompileString
1708
Martin v. Löwis45294a92006-04-18 06:24:08 +00001709- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1710
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001711- All uses of PyStructSequence_InitType have been changed to initialize
1712 the type objects only once, even if the interpreter is initialized
1713 multiple times.
1714
Neal Norwitz61546162006-04-14 05:20:28 +00001715- Bug #1454485, array.array('u') could crash the interpreter. This was
1716 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1717 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1718
1719- Py_UNICODE is unsigned. It was always documented as unsigned, but
1720 due to a bug had a signed value in previous versions.
1721
Tim Peters3a5e8b12006-04-11 01:44:07 +00001722- Patch #837242: ``id()`` of any Python object always gives a positive
1723 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1724 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001725 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001726 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001727
Tim Peters3a5e8b12006-04-11 01:44:07 +00001728 def __hash__(self):
1729 return id(self) # WRONG
1730
1731 because a hash result must be a (short) Python int but it was always
1732 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001733 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001734 was always usable as a hash value before this patch. That's no longer
1735 necessarily so.
1736
1737- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001738 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001739 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001740 #1454844)
1741
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001742- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1743 involving generators that have paused outside of any ``try`` or ``with``
1744 blocks. (In 2.5a1, a paused generator that was part of a reference
1745 cycle could not be garbage collected, regardless of whether it was
1746 paused in a ``try`` or ``with`` block.)

1759- Bug #1117761: bsddb.*open() no longer raises an exception when using
1760 the cachesize parameter.
1761
1762- Bug #1149413: bsddb.*open() no longer raises an exception when using
1763 a temporary db (file=None) with the 'n' flag to truncate on open.

1775 of the process using the returncode attribute, instead of
1776 abusing errno.
1777
Tim Peters711bf302006-04-25 03:31:36 +00001778- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1779 a doctest to be skipped (the code is not run, and the expected output
1780 or exception is ignored).
1781
Nick Coghlanda2268f2006-04-24 04:37:15 +00001782- Fixed contextlib.nested to cope with exceptions being raised and
1783 caught inside exit handlers.
1784
Greg Wardab05edc2006-04-23 03:47:58 +00001785- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1786 hex, octal, or binary; add ``append_const`` action; keep going if
1787 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1788 added ``epilog`` for better help generation).
1789
Tim Peters21fbd572006-04-21 21:18:10 +00001790- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1791 called from a thread spawned as a side effect of importing a module.
1792
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001793- The pydoc module now supports documenting packages contained in
1794 .zip or .egg files.
1795
1796- The pkgutil module now has several new utility functions, such
1797 as ``walk_packages()`` to support working with packages that are either
1798 in the filesystem or zip files.
1799
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001800- The mailbox module can now modify and delete messages from
1801 mailboxes, in addition to simply reading them. Thanks to Gregory
1802 K. Johnson for writing the code, and to the 2005 Google Summer of
1803 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001804
Tim Petersc7605f22006-04-17 21:12:33 +00001805- The ``__del__`` method of class ``local`` in module ``_threading_local``
1806 returned before accomplishing any of its intended cleanup.

1813
Anthony Baxtere29002c2006-04-12 12:07:31 +00001814- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1815 Windows. Bug #1469163.
1816
Phillip J. Eby47032112006-04-11 01:07:43 +00001817- The warnings, linecache, inspect, traceback, site, and doctest modules
1818 were updated to work correctly with modules imported from zipfiles or
1819 via other PEP 302 __loader__ objects.
1820
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001821- Patch #1467770: Reduce usage of subprocess._active to processes which
1822 the application hasn't waited on.

1827
Skip Montanaro262fb922006-04-21 02:31:07 +00001828- The pstats.Stats class accepts an optional stream keyword argument to
1829 direct output to an alternate file-like object.
1830
Anthony Baxter51bcb682006-04-05 14:51:42 +00001831Build
1832-----
1833
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001834- The Makefile now has a reindent target, which runs reindent.py on
1835 the library.
1836
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001837- Patch #1470875: Building Python with MS Free Compiler
1838
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001839- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001840
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001841- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1842 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001843 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001844 CXX from --with-cxx-main, see description in README.
1845
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001846- Patch #1429775: Link extension modules with the shared libpython.
1847
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001848- Fixed a libffi build problem on MIPS systems.
1849
Tim Peters8931ff12006-05-13 23:28:20 +00001850- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1851 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1852 and "%zu" for unsigned integers of type ``size_t``.
1853
Anthony Baxter51bcb682006-04-05 14:51:42 +00001854Tests
1855-----
1856
Nick Coghlanda2268f2006-04-24 04:37:15 +00001857- test_contextlib now checks contextlib.nested can cope with exceptions
1858 being raised and caught inside exit handlers.
1859
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001860- test_cmd_line now checks operation of the -m and -c command switches
1861
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001862- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1863 it separately and by hand. It also wasn't cleaning up its changes to
1864 the current Decimal context.
1865
Thomas Woutersabd08882006-04-26 15:53:30 +00001866- regrtest.py now has a -M option to run tests that test the new limits of
1867 containers, on 64-bit architectures. Running these tests is only sensible
1868 on 64-bit machines with more than two gigabytes of memory. The argument
1869 passed is the maximum amount of memory for the tests to use.

1878-------------
1879
Tim Petersb06d28c2006-05-12 01:57:59 +00001880- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1881
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001882- PEP 343: Added Context Types section to the library reference
1883 and attempted to bring other PEP 343 related documentation into
1884 line with the implementation and/or python-dev discussions.
1885
Tim Peters8dc73d22006-04-24 02:03:16 +00001886- Bug #1337990: clarified that ``doctest`` does not support examples
1887 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001890What's New in Python 2.5 alpha 1?
1891=================================
1892
Anthony Baxterebed3f62006-04-03 15:03:44 +00001893*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001894
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001895Core and builtins
1896-----------------
1897
Nick Coghlan43832302006-04-23 17:04:07 +00001898- PEP 338: -m command line switch now delegates to runpy.run_module
1899 allowing it to support modules in packages and zipfiles
1900
Martin v. Löwisc661b882006-04-20 04:54:23 +00001901- On Windows, .DLL is not an accepted file name extension for
1902 extension modules anymore; extensions are only found if they
1903 end in .PYD.
1904
Martin v. Löwisea62d252006-04-03 10:56:49 +00001905- Bug #1421664: sys.stderr.encoding is now set to the same value as
1906 sys.stdout.encoding.
1907
Neal Norwitz92e212f2006-04-03 04:48:37 +00001908- __import__ accepts keyword arguments.
1909
Georg Brandlccadf842006-03-31 18:54:53 +00001910- Patch #1460496: round() now accepts keyword arguments.
1911
Anthony Baxter262c00a2006-03-30 10:53:17 +00001912- Fixed bug #1459029 - unicode reprs were double-escaped.
1913
Hye-Shik Changd478f342006-03-23 12:32:36 +00001914- Patch #1396919: The system scope threads are reenabled on FreeBSD
1915 5.4 and later versions.
1916
Neal Norwitze98ccf62006-03-23 05:39:47 +00001917- Bug #1115379: Compiling a Unicode string with an encoding declaration
1918 now gives a SyntaxError.
1919
Georg Brandlabd1ff82006-03-18 07:59:59 +00001920- Previously, Python code had no easy way to access the contents of a
1921 cell object. Now, a ``cell_contents`` attribute has been added
1922 (closes patch #1170323).
1923
Tim Peterscf79aac2006-03-16 01:14:46 +00001924- Patch #1123430: Python's small-object allocator now returns an arena to
1925 the system ``free()`` when all memory within an arena becomes unused
1926 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1927 freed. Some applications will see a drop in virtual memory size now,
1928 especially long-running applications that, from time to time, temporarily
1929 use a large number of small objects. Note that when Python returns an
1930 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001931 platform C library will in turn return that memory to the operating system.
1932 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001933 appears to be effective at least on Microsoft C and gcc-based systems.
1934 Thanks to Evan Jones for hard work and patience.
1935
Georg Brandl533ff6f2006-03-08 18:09:27 +00001936- Patch #1434038: property() now uses the getter's docstring if there is
1937 no "doc" argument given. This makes it possible to legitimately use
1938 property() as a decorator to produce a read-only property.
1939
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001940- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1941 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1942 of requiring an int or long in slicing and a few other contexts, enabling
1943 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1944
Neal Norwitz995acdf2006-03-07 05:01:00 +00001945- Fixed various bugs reported by Coverity's Prevent tool.
1946
Brett Cannonbf364092006-03-01 04:25:17 +00001947- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1948 new exception base class, BaseException, which has a new message attribute.
1949 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1950 Raising a string exception now raises a DeprecationWarning.
1951
Thomas Woutersfb609f42006-02-28 16:37:25 +00001952- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1953 explicitly relative, using 'from .module import name' to mean 'from the same
1954 package as this module is in. Imports without dots still default to the
1955 old relative-then-absolute, unless 'from __future__ import
1956 absolute_import' is used.
1957
Brett Cannona7446e32006-02-27 23:39:10 +00001958- Properly check if 'warnings' raises an exception (usually when a filter set
1959 to "error" is triggered) when raising a warning for raising string
1960 exceptions.
1961
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001962- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001963 The name was removed from Include/code.h.
1964
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001965- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001966
Guido van Rossum1968ad32006-02-25 22:38:04 +00001967- Patch 1433928:
1968 - The copy module now "copies" function objects (as atomic objects).
1969 - dict.__getitem__ now looks for a __missing__ hook before raising
1970 KeyError.
1971
Tim Peters84ef21c2006-02-28 20:39:06 +00001972- PEP 343: with statement implemented. Needs ``from __future__ import
1973 with_statement``. Use of 'with' as a variable will generate a warning.
1974 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001975 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001976 The following objects have __context__ methods:
1977 - The built-in file type.
1978 - The thread.LockType type.
1979 - The following types defined by the threading module:
1980 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1981 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001982
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001983- Fix the encodings package codec search function to only search
1984 inside its own package. Fixes problem reported in patch #1433198.
1985
1986 Note: Codec packages should implement and register their own
1987 codec search function. PEP 100 has the details.
1988
Tim Peters9ea89d22006-06-04 03:26:02 +00001989- PEP 353: Using ``Py_ssize_t`` as the index type.
1990
1991- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1992 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1993 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1994 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1995 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001996
Neal Norwitzfc76d632006-01-10 06:03:13 +00001997- Patch #1400181, fix unicode string formatting to not use the locale.
1998 This is how string objects work. u'%f' could use , instead of .
1999 for the decimal point. Now both strings and unicode always use periods.
2000
Neal Norwitz671b9e32006-01-09 07:07:12 +00002001- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2002 configure would break checking curses.h.
2003
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002004- Bug #959576: The pwd module is now builtin. This allows Python to be
2005 built on UNIX platforms without $HOME set.
2006
Neal Norwitzc10978f2005-12-19 06:07:16 +00002007- Bug #1072182, fix some potential problems if characters are signed.
2008
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002009- Bug #889500, fix line number on SyntaxWarning for global declarations.
2010
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002011- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2012
Neal Norwitze7214a12005-12-18 05:03:17 +00002013- Support for converting hex strings to floats no longer works.
2014 This was not portable. float('0x3') now raises a ValueError.
2015
Barry Warsaw2a38a862005-12-18 01:27:35 +00002016- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002017 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002018 is now displayed in interactive prompt banner.
2019
Georg Brandlfa166682005-12-17 21:45:17 +00002020- Implementation of PEP 341 - Unification of try/except and try/finally.
2021 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002022 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002023
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002024- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2025 now encodes backslash correctly.
2026
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002027- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2028
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002029- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002030 and long longs.
2031
Neal Norwitz67715f02005-11-09 06:59:35 +00002032- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002033 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002034 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002035
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002036- Replaced most Unicode charmap codecs with new ones using the
2037 new Unicode translate string feature in the builtin charmap
2038 codec; the codecs were created from the mapping tables available
2039 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2040 encodings now include a mapping for the Apple logo)
2041
Tim Peterse3547fd2005-12-16 23:13:57 +00002042- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002043
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002044- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002045
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002046- A new AST parser implementation was completed. The abstract
2047 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002048 to Python code; an _ast module was added.

Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002050- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002051 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2052
Neal Norwitz708e51a2005-10-03 04:48:15 +00002053- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2054
Neal Norwitz11bd1192005-10-03 00:54:56 +00002055- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2056 Provide a warning when a directory is passed on the command line.
2057
Neal Norwitz40d37812005-10-02 01:48:49 +00002058- Fix segfault with invalid coding.
2059
2060- SF bug #772896: unknown encoding results in MemoryError.
2061
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002062- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002063 supported a __len__() method which evaluated to False when the iterator
2064 was empty.
2065
Guido van Rossum630db602005-09-20 18:49:54 +00002066- On 64-bit platforms, when __len__() returns a value that cannot be
2067 represented as a C int, raise OverflowError.
2068
Skip Montanarof8948ca2005-09-19 03:54:46 +00002069- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002070 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002071
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002072- SF bug #893549: parsing keyword arguments was broken with a few format
2073 codes.
2074
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002075- Changes donated by Elemental Security to make it work on AIX 5.3
2076 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2077 bug #105470: test_pwd fails on 64bit system (Opteron).
2078
Guido van Rossum539c6622005-09-14 17:49:54 +00002079- Changes donated by Elemental Security to make it work on HP-UX 11 on
2080 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2081
Georg Brandl4550b8d2005-08-26 06:43:52 +00002082- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002083 (fixes bug #1119418).
2084
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002085- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2086
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002087- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2088 exceptions that cause a function to exit.
2089
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002090- The implementation of set() and frozenset() was revised to use its
2091 own internal data structure. Memory consumption is reduced by 1/3
2092 and there are modest speed-ups as well. The API is unchanged.
2093
Tim Petersde7990b2005-07-17 23:45:23 +00002094- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2095
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002096- SF bug #1229429: PyObject_CallMethod failed to decrement some
2097 reference counts in some error exit cases.
2098
Tim Petersecc6e6a2005-07-10 22:30:55 +00002099- SF bug #1185883: Python's small-object memory allocator took over
2100 a block managed by the platform C library whenever a realloc specified
2101 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002102 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002103 portable way to copy data from the C-managed block into Python's
2104 small-object space without risking a memory fault. Python's small-object
2105 realloc now leaves such blocks under the control of the platform C
2106 realloc.
2107
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002108- SF bug #1232517: An overflow error was not detected properly when
2109 attempting to convert a large float to an int in os.utime().
2110
Raymond Hettinger3296e692005-06-29 23:29:56 +00002111- SF bug #1224347: hex longs now print with lowercase letters just
2112 like their int counterparts.
2113
Michael W. Hudson188d4362005-06-20 16:52:57 +00002114- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2115 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2116 interpreter states; back out that fix and do a better job (see
2117 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2118 for a longer write-up of the problem).
2119
Michael W. Hudsondf888462005-06-03 14:41:55 +00002120- SF patch #1180995: marshal now uses a binary format by default when
2121 serializing floats.
2122
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002123- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2124 the routines that promise to produce IEEE 754 binary representations
2125 of floats now simply copy bytes around.
2126
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002127- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2128 278.
2129
Brett Cannonc3647ac2005-04-26 03:45:26 +00002130- patch #1109424: int, long, float, complex, and unicode now check for the
2131 proper magic slot for type conversions when subclassed. Previously the
2132 magic slot was ignored during conversion. Semantics now match the way
2133 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002134 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002135 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002136 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002137
Barry Warsawc8d907c2005-04-19 23:43:40 +00002138- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2139 NULL, now raise an AttributeError when attempting to set or delete the
2140 attribute. Previously a TypeError was raised, but this was inconsistent
2141 with the equivalent pure-Python implementation.
2142
Michael W. Hudson774479c2005-04-18 08:46:17 +00002143- It is now safe to call PyGILState_Release() before
2144 PyEval_InitThreads() (note that if there is reason to believe there
2145 are multiple threads around you still must call PyEval_InitThreads()
2146 before using the Python API; this fix is for extension modules that
2147 have no way of knowing if Python is multi-threaded yet).
2148
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002149- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2150 disabled caused a crash.
2151
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002152- Bug #1165306: instancemethod_new allowed the creation of a method
2153 with im_class == im_self == NULL, which caused a crash when called.
2154
Tim Petersecc6e6a2005-07-10 22:30:55 +00002155- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002156 fixes the crash seen in bug #1165761
2157
Raymond Hettinger96229b12005-03-11 06:49:40 +00002158- Added two new builtins, any() and all().
2159
Brett Cannon409d8f22005-03-05 06:47:57 +00002160- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002161 (e.g., ``class C(): pass`` is no longer a syntax error).
2162 Patch #1176012 added support to the 'parser' module and 'compiler' package
2163 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002164
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002165- Patch #1115086: Support PY_LONGLONG in structmember.
2166
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002167- Bug #1155938: new style classes did not check that __init__() was
2168 returning None.
2169
Tim Petersecc6e6a2005-07-10 22:30:55 +00002170- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002171 ('\') with a specific error message.
2172
Martin v. Löwisff232d72005-03-03 09:24:38 +00002173- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2174
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002175- Bug #1124295: the __name__ attribute of file objects was
2176 inadvertently made inaccessible in restricted mode.
2177
Tim Petersecc6e6a2005-07-10 22:30:55 +00002178- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002179 an ferror() call.
2180
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002181- min() and max() now support key= arguments with the same meaning as in
2182 list.sort().
2183
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002184- The peephole optimizer now performs simple constant folding in expressions:
2185 (2+3) --> (5).
2186
Raymond Hettingera422c342005-01-11 03:03:27 +00002187- set and frozenset objects can now be marshalled. SF #1098985.
2188
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002189- Bug #1077106: Poor argument checking could cause memory corruption
2190 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002191
Jeremy Hyltonab630502005-02-04 18:44:06 +00002192- The parser did not complain about future statements in illegal
2193 positions. It once again reports a syntax error if a future
2194 statement occurs after anything other than a doc string.
2195
Neil Schemenauercf52c072005-08-12 17:34:58 +00002196- Change the %s format specifier for str objects so that it returns a
2197 unicode instance if the argument is not an instance of basestring and
2198 calling __str__ on the argument returns a unicode instance.
2199
Tim Petersf4e69282006-02-27 17:15:31 +00002200- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2201 current thread state when the auto-GIL-state machinery knows about
2202 it (since the thread state is being deleted, continuing to remember it
2203 can't help, but can hurt if another thread happens to get created with
2204 the same thread id).
2205
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002206Extension Modules
2207-----------------
2208

Neal Norwitz10be10c2006-03-16 06:50:13 +00002222 util, whatsound, whrandom, zmod
2223
2224- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2225
2226- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002227 is deprecated. The undocumented re.engine variable no longer exists.
2228

2230 SS2 (single-shift 2) escape sequences correctly.
2231
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002232- The unicodedata module was updated to the 4.1 version of the Unicode
2233 database. The 3.2 version is still available as unicodedata.db_3_2_0
2234 for applications that require this specific version (such as IDNA).
2235
Neal Norwitzb62c4332006-03-04 18:35:47 +00002236- The timing module is no longer built by default. It was deprecated
2237 in PEP 4 in Python 2.0 or earlier.
2238
Guido van Rossum1968ad32006-02-25 22:38:04 +00002239- Patch 1433928: Added a new type, defaultdict, to the collections module.
2240 This uses the new __missing__ hook behavior added to dict (see above).
2241
Georg Brandldbd83392006-02-20 09:42:33 +00002242- Bug #854823: socketmodule now builds on Sun platforms even when
2243 INET_ADDRSTRLEN is not defined.
2244
Georg Brandlf4f44152006-02-18 22:29:33 +00002245- Patch #1393157: os.startfile() now has an optional argument to specify
2246 a "command verb" to invoke on the file.
2247
Neal Norwitz082b2df2006-02-07 07:04:46 +00002248- Bug #876637, prevent stack corruption when socket descriptor

2256 than the system default domain.
2257
Martin v. Löwis14694662006-02-03 12:54:16 +00002258- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2259 are reported, the limit on path name lengths is removed, and stat reports
2260 WindowsError now (instead of OSError).
2261
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002262- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

2337 the request code argument, which results in more C-like behaviour
2338 for large or negative values.
2339
Tim Petersecc6e6a2005-07-10 22:30:55 +00002340- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

2355
Raymond Hettinger984f9bb2005-03-09 16:38:48 +00002356- operator.itemgetter() and operator.attrgetter() now support retrieving

2381 args tuple returned by __reduce__().
2382
Raymond Hettingerb2594052004-12-05 09:25:51 +00002383- itertools.islice() now accepts None for the start and step arguments.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002396- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2397 been renamed to have only a single underscore prefix. This was done to
2398 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002399
Nick Coghlan43832302006-04-23 17:04:07 +00002400- PEP 338: new module runpy defines a run_module function to support
2401 executing modules which provide access to source code or a code object
2402 via the PEP 302 import mechanisms.
2403
Anthony Baxter93f5b932006-04-03 08:05:07 +00002404- The email module's parsedate_tz function now sets the daylight savings

2412 in attribute values.
2413
Anthony Baxterc51ee692006-04-01 00:57:31 +00002414- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002415 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002416 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002417 module will not be built.
2418
Tim Petersc17976e2006-04-01 00:26:53 +00002419- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2420 aren't officially supported here, and trying to use them will probably
2421 raise an exception some day. But dicts have been allowed, and "mostly
2422 worked", so support for them won't go away without warning.
2423
Georg Brandl338ef7d2006-03-31 18:42:16 +00002424- Bug #1445068: getpass.getpass() can now be given an explicit stream
2425 argument to specify where to write the prompt.
2426
Georg Brandl22ec80b2006-03-31 18:25:44 +00002427- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2434
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002435- Queue.Queue objects now support .task_done() and .join() methods
2436 to make it easier to monitor when daemon threads have completed
2437 processing all enqueued tasks. Patch #1455676.
2438
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002439- popen2.Popen objects now preserve the command in a .cmd attribute.

2442
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002443- email 4.0 package now integrated. This is largely the same as the email 3.0
2444 package that was included in Python 2.3, except that PEP 8 module names are
2445 now used (e.g. mail.message instead of email.Message). The MIME classes
2446 have been moved to a subpackage (e.g. email.mime.text instead of
2447 email.MIMEText). The old names are still supported for now. Several
2448 deprecated Message methods have been removed and lots of bugs have been
2449 fixed. More details can be found in the email package documentation.
2450
Walter Dörwald40108c92006-03-27 08:15:44 +00002451- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2452 (a subclass of tuple) that provides incremental decoders and encoders
2453 (a way to use stateful codecs without the stream API). Python functions
2454 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2455 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2456 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002457
Walter Dörwald067db482006-03-15 22:17:27 +00002458- Patch #1359365: Calling next() on a closed StringIO.String object raises
2459 a ValueError instead of a StopIteration now (like file and cString.String do).
2460 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2461 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002462
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002463- A regrtest option -w was added to re-run failed tests in verbose mode.

2473
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002474- PEP 343: new module contextlib.py defines decorator @contextmanager
2475 and helpful context managers nested() and closing().
2476
Martin v. Löwis415ed932006-02-27 19:56:30 +00002477- The compiler package now supports future imports after the module docstring.
2478

Martin v. Löwis3e865952006-01-24 15:51:21 +00002511 specifications, raises IOErrors when proxies for unsupported protocols
2512 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00002535 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2536 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2537 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2538 Ronald L. Rivest offered this advice for Python:
2539
2540 "The consensus of researchers in this area (at least as
2541 expressed at the NIST Hash Function Workshop 10/31/05),
2542 is that SHA-256 is a good choice for the time being, but
2543 that research should continue, and other alternatives may
2544 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002545
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002546- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandlb9256022005-08-24 18:46:39 +00002592- Patch #1062060: urllib.urlretrieve() now raises a new exception, named
2593 ContentTooShortException, when the actually downloaded size does not
2594 match the Content-Length header.
2595
Martin v. Löwis0a5d4a22005-08-24 14:55:22 +00002596- Bug #1121494: distutils.dir_utils.mkpath now accepts Unicode strings.
2597
Martin v. Löwis56066d22005-08-24 07:38:12 +00002598- Bug #1178484: Return complete lines from codec stream readers
2599 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002600 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002601

2621
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00002622- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
2623 to W3C name (404 -> 'Not Found'). RFE #1216944.
2624
Georg Brandl9e43acf2005-07-04 17:16:07 +00002625- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2626 as this can cause problems with apps closing all file descriptors.

2639 Bug #1224621.
2640
Raymond Hettinger68c04532005-06-10 11:05:19 +00002641- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002642 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002643 the generate_tokens() function now accepts a callable argument that
2644 terminates by raising StopIteration.
2645
Georg Brandl9166e1a2005-06-04 09:20:03 +00002646- Bug #1196315: fix weakref.WeakValueDictionary constructor.

2649 component of the path.
2650
Skip Montanaro174dd222005-05-14 20:54:16 +00002651- Patch #1120353: The xmlrpclib module provides better, more transparent,
2652 support for datetime.{datetime,date,time} objects. With use_datetime set
2653 to True, applications shouldn't have to fiddle with the DateTime wrapper
2654 class at all.
2655
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002656- distutils.commands.upload was added to support uploading distribution

2658
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002659- distutils.commands.register now encodes the data as UTF-8 before posting
2660 them to PyPI.
2661
Raymond Hettinger267b8682005-03-27 10:47:39 +00002662- decimal operator and comparison methods now return NotImplemented
2663 instead of raising a TypeError when interacting with other types. This
2664 allows other classes to implement __radd__ style methods and have them
2665 work as expected.
2666
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002667- Bug #1163325: Decimal infinities failed to hash. Attempting to
2668 hash a NaN raised an InvalidOperation instead of a TypeError.
2669
Tim Petersecc6e6a2005-07-10 22:30:55 +00002670- Patch #918101: Add tarfile open mode r|* for auto-detection of the

2704
Guido van Rossumd0641422005-02-03 15:01:24 +00002705- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2706 disables recursive traversal through instance attributes, which can
2707 be exploited in various ways.
2708
Tim Peterse3547fd2005-12-16 23:13:57 +00002709- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002710 flags on the HTTP listening socket.
2711
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002712- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2713 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2714
Fred Drakefbdeaad2006-07-29 16:56:15 +00002715- Patches #893642, #1039083: add allow_none, encoding arguments to
2716 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002717
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002718- Bug #1110478: Revert os.environ.update to do putenv again.
2719
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002720- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2721
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002722- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2723
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002724- Enhancements to the csv module:
2725
2726 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002727 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002728 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002729 + Dialect parameter parsing has been re-implemented to improve error
2730 reporting.
2731 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2732 dictates.
2733 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002734 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002735 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002736 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2737 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002738 + reader now allows \r characters to be quoted (previously it only allowed
2739 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002740 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002741 + Dialect classes passed to the module are no longer instantiated by
2742 the module before being parsed (the former validation scheme required
2743 this, but the mechanism was unreliable).
2744 + The dialect registry now contains instances of the internal
2745 C-coded dialect type, rather than references to python objects.
2746 + the internal c-coded dialect type is now immutable.
2747 + register_dialect now accepts the same keyword dialect specifications
2748 as the reader and writer, allowing the user to register dialects
2749 without first creating a dialect class.
2750 + a configurable limit to the size of parsed fields has been added -
2751 previously, an unmatched quote character could result in the entire
2752 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002753 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002754 the parser field size limit (returning the former limit). The initial
2755 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002756 + A line_num attribute has been added to the reader object, which tracks
2757 the number of lines read from the source iterator. This is not
2758 the same as the number of records returned, as records can span
2759 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002760 + reader and writer objects were not being registered with the cyclic-GC.
2761 This has been fixed.
2762
Brett Cannone6539c42005-01-08 02:43:53 +00002763- _DummyThread objects in the threading module now delete self.__block that is
2764 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2765 lock primitives tend to be limited in number and thus should not be wasted on
2766 a _DummyThread object. Fixes bug #1089632.
2767
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002768- The imghdr module now detects Exif files.
2769
Raymond Hettinger6065d322004-12-20 23:51:53 +00002770- StringIO.truncate() now correctly adjusts the size attribute.
2771 (Bug #951915).
2772
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002773- locale.py now uses an updated locale alias table (built using
2774 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2775 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002776 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002777
Raymond Hettinger3557f422004-12-07 12:02:02 +00002778- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2779
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002780- the pickle module no longer accepts the deprecated None option in the
2781 args tuple returned by __reduce__().
2782
Brett Cannon84667c02004-12-07 03:25:18 +00002783- optparse now optionally imports gettext. This allows its use in setup.py.
2784
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002785- the pickle module no longer uses the deprecated bin parameter.
2786
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002787- the shelve module no longer uses the deprecated binary parameter.
2788
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002789- the pstats module no longer uses the deprecated ignore() method.
2790
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002791- the filecmp module no longer uses the deprecated use_statcache argument.
2792
Raymond Hettinger664347b2004-12-04 21:21:53 +00002793- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2794 extended or overridden by subclasses. Formerly, the subclassed method would
2795 be ignored by the rest of the module. (Bug #1078905).
2796
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002797- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002798 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002799
Walter Dörwald36733692004-12-22 12:50:50 +00002800- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2801 once when a size argument is given. This prevents a buffer overflow in the
2802 tokenizer with very long source lines.
2803
Barry Warsaw538561e2006-01-01 21:48:54 +00002804- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2805 immediately after creating the object, without any intervening
2806 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002807
Skip Montanaro05885812005-01-16 20:48:27 +00002808- The reconvert.quote function can now emit triple-quoted strings. The
2809 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002810
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002811- ``UserString.MutableString`` now supports negative indices in
2812 ``__setitem__`` and ``__delitem__``
2813
Greg Ward40407942005-03-05 02:53:17 +00002814- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2815 correctly.
2816
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002817- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2818 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2819 character even if the user has passed a size parameter to get a proper
2820 line ending. Remove the special handling of a "\r\n" that has been split
2821 between two lines.
2822
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002823- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2824 about illegal code points. The codec now supports PEP 293 style error
2825 handlers.
2826
Walter Dörwald78a78b02005-09-01 12:04:29 +00002827- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002828 from the input stream, so that the output is a byte string in the correct
2829 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002830
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002831- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2832 considering it exactly like a '*'.
2833
Walter Dörwald007f8df2005-10-09 19:42:27 +00002834- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2835 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002836
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002837- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2838
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002839- Patch #1413711: Certain patterns of differences were making difflib
2840 touch the recursion limit.
2841
Walter Dörwald58917a62006-03-31 15:26:22 +00002842- Bug #947906: An object oriented interface has been added to the calendar
2843 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002844 called as a script (e.g. via ``python -mcalendar``). Localized month and
2845 weekday names can be ouput (even if an exotic encoding is used) using
2846 special classes that use unicode.

2850
Neal Norwitz602d3392006-03-31 08:21:40 +00002851- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2852 by using -mieee gcc option.
2853

2855
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002856- Build support for Win64-AMD64 was added.
2857
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002858- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2859
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002860- Patch #881820: look for openpty and forkpty also in libbsd.
2861
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002862- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2863 The zlib module is now builtin on Windows.
2864
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002865- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2866
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002867- Bug #1189330: configure did not correctly determine the necessary
2868 value of LINKCC if python was built with GCC 4.0.
2869
Trent Mick8321b422005-07-26 02:29:21 +00002870- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2871 vulnerability in zlib 1.2.1 and 1.2.2.
2872
Brett Cannon08cd5982005-04-24 22:26:38 +00002873- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2874 flags that change binary compatibility. Changes were also made to
2875 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002876 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002877
Bob Ippolitoed233462005-03-29 13:47:59 +00002878- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2879 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2880 no longer exists). This configure patch makes things right.
2881
Martin v. Löwise2713be2005-03-08 15:03:08 +00002882- Bug #1158607: Build with --disable-unicode again.
2883
Brett Cannon46d96232005-02-16 00:07:19 +00002884- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2885 defined. Discovered as a result of not being able to build on OS X.
2886
Brett Cannon516592f2004-12-07 00:42:59 +00002887- setup.py now uses the directories specified in LDFLAGS using the -L option
2888 and in CPPFLAGS using the -I option for adding library and include
2889 directories, respectively, for compiling extension modules against. This has
2890 led to the core being compiled using the values in CPPFLAGS. It also removes
2891 the need for the special-casing of both DarwinPorts and Fink for darwin since
2892 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2893 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2894 Fink, ``-I/opt/local/include`` for DarwinPorts).
2895
Brett Cannon43802422005-02-10 20:48:03 +00002896- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2897 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2898 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2899 Closes bug #1096244. Thanks Gregory Bond.

2902-----
2903
Tim Petersc9d78aa2006-03-26 23:27:58 +00002904- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2905 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2906 is obtained via the ``PyObject_`` family, it must be released via the
2907 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2908 always been officially true, but when Python's small-object allocator was
2909 introduced, an attempt was made to cater to a few extension modules
2910 discovered at the time that obtained memory via ``PyObject_New`` but
2911 released it via ``PyMem_DEL``. It's years later, and if such code still
2912 exists it will fail now (probably with segfaults, but calling wrong
2913 low-level memory management functions can yield many symptoms).
2914
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002915- Added a C API for set and frozenset objects.
2916

2918
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002919- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2920 mapping argument now. This string is used as a mapping table. Byte values
2921 greater than the length of the string and 0xFFFE are treated as undefined
2922 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002929
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002930- Patch #1276356: New resource "urlfetch" is implemented. This enables
2931 even impatient people to run tests that require remote files.
