Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000885 Instead, the equal (==) and unequal (!=) comparison operators will
886 now issue a UnicodeWarning and interpret the two objects as
887 unequal. The UnicodeWarning can be filtered as desired using
888 the warning framework, e.g. silenced completely, turned into an
889 exception, logged, etc.
890
891 Note that compare operators other than equal and unequal will still
892 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000893
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000894- Fix segfault when doing string formatting on subclasses of long.
895
896- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
897 with new-style classes.
898
899- Fix bug related to __len__ functions returning negative values with
900 classic classes.
901
902- Patch #1538606, Fix __index__() clipping. There were some problems
903 discovered with the API and how integers that didn't fit into Py_ssize_t
904 were handled. This patch attempts to provide enough alternatives
905 to effectively use __index__.
906
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000907- Bug #1536021: __hash__ may now return long int; the final hash
908 value is obtained by invoking hash on the long int.
909
Thomas Hellerab1049c2006-08-08 17:37:00 +0000910- Bug #1536786: buffer comparison could emit a RuntimeWarning.
911
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000912- Bug #1535165: fixed a segfault in input() and raw_input() when
913 sys.stdin is closed.
914
Thomas Heller74d36f02006-08-04 18:17:40 +0000915- On Windows, the PyErr_Warn function is now exported from
916 the Python dll again.
917
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000918- Bug #1191458: tracing over for loops now produces a line event
919 on each iteration. Fixing this problem required changing the .pyc
920 magic number. This means that .pyc files generated before 2.5c1
921 will be regenerated.
922
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000923- Bug #1333982: string/number constants were inappropriately stored
924 in the byte code and co_consts even if they were not used, ie
925 immediately popped off the stack.
926
Georg Brandle9462c72006-08-04 18:03:37 +0000927- Fixed a reference-counting problem in property().
928
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000929
930Library
931-------
932
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000933- Fix a bug in the ``compiler`` package that caused invalid code to be
934 generated for generator expressions.
935
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000936- The distutils version has been changed to 2.5.0. The change to
937 keep it programmatically in sync with the Python version running
938 the code (introduced in 2.5b3) has been reverted. It will continue
939 to be maintained manually as static string literal.
940
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000941- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000942 and this cannot be converted to the required C type, an exception is
943 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000944 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000945
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000946- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000947 an exception.
948
Tim Peterscbdd3502006-09-05 01:47:53 +0000949- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000950 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000951 workarounds for clocks with low resolution, to stop the code yielding
952 duplicate UUIDs.
953
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000954- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
955 before raising SystemExit, allowing IDLE to honor quit() and exit().
956
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000957- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
958
Georg Brandl7a1af772006-08-14 21:55:28 +0000959- Patch #1536071: trace.py should now find the full module name of a
960 file correctly even on Windows.
961
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000962- logging's atexit hook now runs even if the rest of the module has
963 already been cleaned up.
964
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000965- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000966
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000967- Bug #1531405, format_exception no longer raises an exception if
968 str(exception) raised an exception.
969
Neil Schemenauer06ded092006-08-04 16:20:30 +0000970- Fix a bug in the ``compiler`` package that caused invalid code to be
971 generated for nested functions.
972
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000973

978
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000979- Patch #1511317: don't crash on invalid hostname (alias) info.
980
Georg Brandl3335a7a2006-08-14 21:42:55 +0000981- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
982 raises the correct exceptions.
983
Thomas Heller1ce433e2006-08-14 16:20:04 +0000984- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
985 '-no-stack-protector' compiler flag for OpenBSD has been removed.
986
Thomas Heller86720042006-08-14 11:17:48 +0000987- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
988 uses the _as_parameter_ attribute when objects are passed to foreign
989 function calls. The ctypes version number was changed to 1.0.1.
990
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000991- Bug #1530559, struct.pack raises TypeError where it used to convert.
992 Passing float arguments to struct.pack when integers are expected
993 now triggers a DeprecationWarning.
994
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000995
996Tests

Neal Norwitz003c9e22006-08-11 06:09:41 +00001002- test_mailbox should now work on cygwin versions 2006-08-10 and later.
1003
Georg Brandl9908d162006-08-06 07:06:33 +00001004- Bug #1535182: really test the xreadlines() method of bz2 objects.
1005
Andrew MacIntyre16ee33a2006-08-06 12:37:03 +00001006- test_threading now skips testing alternate thread stack sizes on
1007 platforms that don't support changing thread stack size.

1017-----
1018
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +00001019- Bug #1535502, build _hashlib on Windows, and use masm assembler
1020 code in OpenSSL.
1021
Thomas Hellerdb7b4432006-08-04 19:49:31 +00001022- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.
1023
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001024- Bug #1530448, ctypes build failure on Solaris 10 was fixed.
Thomas Heller17984892006-08-04 18:57:34 +00001025
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001026
Tim Peters4643c2f2006-08-10 22:45:34 +00001027C API
1028-----
1029
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001030- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1031
Tim Peters4643c2f2006-08-10 22:45:34 +00001032- Bug #1069160. Internal correctness changes were made to
1033 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1034 the documentation was changed to state that the return value
1035 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001038What's New in Python 2.5 beta 3?
1039================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001040
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001041*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001042
1043Core and builtins
1044-----------------
1045
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001046- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001047 returned a long (see PEP 353).
1048
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001049- Bug #1515471: string.replace() accepts character buffers again.
1050
Neal Norwitz07aadb12006-07-30 06:55:48 +00001051- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1052 This provides the proper warning for struct.pack().
1053 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1054
Neal Norwitz0d62a062006-07-30 06:53:31 +00001055- Patch #1531113: Fix augmented assignment with yield expressions.
1056 Also fix a SystemError when trying to assign to yield expressions.
1057
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001058- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1059 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1060 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1061 excessive filesystem operations during imports.
1062
Tim Petersbc24eee2006-07-27 01:14:53 +00001063- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1064 operations on signed longs that are formally undefined by C.
1065 Unfortunately, at least one compiler now cares about that, so complicated
1066 the code to make that compiler happy again.
1067
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001068- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1069
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001070- Patch #1232023: Stop including current directory in search
1071 path on Windows.
1072
Neal Norwitze1fdb322006-07-21 05:32:28 +00001073- Fix some potential crashes found with failmalloc.
1074
Neal Norwitze7563102006-07-17 01:00:16 +00001075- Fix warnings reported by Klocwork's static analysis tool.
1076
Neal Norwitz84be93b2006-07-16 01:50:38 +00001077- Bug #1512814, Fix incorrect lineno's when code within a function
1078 had more than 255 blank lines.
1079
Georg Brandl9dceedb2006-07-12 15:31:17 +00001080- Patch #1521179: Python now accepts the standard options ``--help`` and
1081 ``--version`` as well as ``/?`` on Windows.
1082
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001083- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001084 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001085 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001086
Tim Peters112aad32006-07-19 00:03:19 +00001087- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001088 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001089 new ``sys._current_frames()`` returns a dictionary with one entry,
1090 mapping the faux "thread id" 0 to the current frame.
1091
Ronald Oussoren3075e162006-07-25 20:28:55 +00001092- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001093
Ronald Oussoren3075e162006-07-25 20:28:55 +00001094
Neal Norwitza1f10902006-07-12 07:28:29 +00001095Library
1096-------
1097
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001098- Correction of patch #1455898: In the mbcs decoder, set final=False
1099 for stream decoder, but final=True for the decode function.
1100
Georg Brandl07fec3a2006-08-01 18:49:24 +00001101- os.urandom no longer masks unrelated exceptions like SystemExit or
1102 KeyboardInterrupt.
1103
Tim Peters4643c2f2006-08-10 22:45:34 +00001104- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001105 shutil.copytree on Windows
1106
Georg Brandle34ac7c2006-07-30 11:07:23 +00001107- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1108 refers to file descriptors, not file objects.
1109
Tim Peterscbdd3502006-09-05 01:47:53 +00001110- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001111 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001112 #1513611, and probably others.
1113
Georg Brandledd9b0d2006-07-29 09:33:26 +00001114- Bug #1441397: The compiler module now recognizes module and function
1115 docstrings correctly as it did in Python 2.4.
1116
Tim Peters6f681472006-07-27 23:44:37 +00001117- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1118 lost that tests are sorted by name before being run. This rarely
1119 matters for well-written tests, but can create baffling symptoms if
1120 side effects from one test to the next affect outcomes. ``DocTestFinder``
1121 has been changed to sort the list of tests it returns.
1122
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001123- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001124 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001125
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001126- Bug #978833: Really close underlying socket in _socketobject.close.
1127
Georg Brandldb232dc2006-08-20 13:15:43 +00001128- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1129 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001130
Georg Brandlcf0c1722006-07-26 07:23:32 +00001131- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1132 to recursive calls and call it with the failing package name.
1133
Martin v. Löwis0b483032006-07-25 09:53:12 +00001134- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1135
Georg Brandlc13c34c2006-07-24 14:09:56 +00001136- Patch #1515343: Fix printing of deprecated string exceptions with a
1137 value in the traceback module.
1138
Greg Ward48fae7a2006-07-23 16:05:51 +00001139- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1140
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001141- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1142
Brett Cannoncaebe222006-07-18 04:41:36 +00001143- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1144 argument tuple. For arguments where zero is illegal, the value is forced to
1145 the minimum value that is correct. This is to support an undocumented but
1146 common way people used to fill in inconsequential information in the time
1147 tuple pre-2.4.
1148
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001149- Patch #1220874: Update the binhex module for Mach-O.
1150
Barry Warsawb110bad2006-07-21 14:51:07 +00001151- The email package has improved RFC 2231 support, specifically for
1152 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1153 (name*0=<blah>) parameter continuations. This may change the types of
1154 values returned from email.message.Message.get_param() and friends.
1155 Specifically in some cases where non-encoded continuations were used,
1156 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1157 will just return the string (since non-encoded continuations don't have
1158 charset and language parts).
1159
1160 Also, whereas % values were decoded in all parameter continuations, they are
1161 now only decoded in encoded parameter parts.
1162
Ronald Oussoren3075e162006-07-25 20:28:55 +00001163- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1164
1165- Bug #1517996: IDLE now longer shows the default Tk menu when a
1166 path browser, class browser or debugger is the frontmost window on MacOS X
1167
Barry Warsaw00decd72006-07-27 23:43:15 +00001168- Patch #1520294: Support for getset and member descriptors in types.py,
1169 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1170 of an object against these built-in types and more importantly, for getting
1171 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001174Extension Modules
1175-----------------
1176
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001177- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1178 a socket operation on a socket with a timeout, the exception will be
1179 caught correctly. Previously, the exception was not caught.
1180
Thomas Heller1393d6a2006-07-28 21:43:20 +00001181- Patch #1529514: The _ctypes extension is now compiled on more
1182 openbsd target platforms.
1183
Tim Peters9cab5932006-07-28 00:30:00 +00001184- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1185 a memory leak, affecting pickles and deep copies.
1186
Tim Petersbc24eee2006-07-27 01:14:53 +00001187- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001188 Paul Eggert.
1189
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001190- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1191
Thomas Hellerce049a02006-07-14 17:51:14 +00001192- Patch #1521817: Index range checking on ctypes arrays containing
1193 exactly one element enabled again. This allows iterating over these
1194 arrays, without the need to check the array size before.
1195
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001196- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001197 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001198 /dev/null in certain cases; this is now fixed.
1199
Thomas Heller47d7a062006-07-12 08:43:47 +00001200- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1201 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001202
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001203- Because of a misspelled preprocessor symbol, ctypes was always
1204 compiled without thread support; this is now fixed.
1205
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001206- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1207 methods now allow their database parameter to be None as the
1208 sleepycat API allows.
1209
Matt Flemingec926502006-07-28 11:27:27 +00001210- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1211 bluetooth API compared with Linux and FreeBSD.
1212
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001213Tests
1214-----
1215
1216- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1217 how long the test file should take to play. Now accepts taking 2.93 secs
1218 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1219
Georg Brandl4793aa32006-07-28 18:31:39 +00001220- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1221 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1222 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +00001223
Martin v. Löwis0907f4d2006-07-30 14:09:47 +00001224Build
1225-----
1226
1227- Bug #1439538: Drop usage of test -e in configure as it is not portable.
1228
Ronald Oussoren26cad082006-08-01 21:00:57 +00001229Mac
1230---
1231
1232- PythonLauncher now works correctly when the path to the script contains
1233 characters that are treated specially by the shell (such as quotes).
1234
1235- Bug #1527397: PythonLauncher now launches scripts with the working directory
1236 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001237 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001238 expect.

Georg Brandlad29e632006-06-21 17:45:17 +00001241What's New in Python 2.5 beta 2?
1242================================

Georg Brandlad29e632006-06-21 17:45:17 +00001245
1246Core and builtins
1247-----------------
1248
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001249- Bug #1441486: The literal representation of -(sys.maxint - 1)
1250 again evaluates to a int object, not a long.
1251
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001252- Bug #1501934: The scope of global variables that are locally assigned
1253 using augmented assignment is now correctly determined.
1254
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001255- Bug #927248: Recursive method-wrapper objects can now safely
1256 be released.
1257
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001258- Bug #1417699: Reject locale-specific decimal point in float()
1259 and atof().
1260
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001261- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1262 omit a default "error" argument for NULL pointer. This allows
1263 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001264
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001265- Bug #1519018: 'as' is now validated properly in import statements.
1266
Neal Norwitz28746ab2006-07-09 22:14:42 +00001267- On 64 bit systems, int literals that use less than 64 bits are
1268 now ints rather than longs.
1269
Neal Norwitzed657552006-07-10 00:04:44 +00001270- Bug #1512814, Fix incorrect lineno's when code at module scope
1271 started after line 256.
1272
Tim Peters32a83612006-07-10 21:08:24 +00001273- New function ``sys._current_frames()`` returns a dict mapping thread
1274 id to topmost thread stack frame. This is for expert use, and is
1275 especially useful for debugging application deadlocks. The functionality
1276 was previously available in Fazal Majid's ``threadframe`` extension
1277 module, but it wasn't possible to do this in a wholly threadsafe way from
1278 an extension.
1279

1284 VS 2003.
1285
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001286- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1287
Tim Peters32a83612006-07-10 21:08:24 +00001288- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001289 environment variable to be set in order to the SDK environment
1290 for finding the compiler, include files, etc.

1293
Nick Coghlan2d792252006-07-06 13:47:18 +00001294- warnings.py now ignores ImportWarning by default
1295
Thomas Woutersadd19112006-07-05 11:03:49 +00001296- string.Template() now correctly handles tuple-values. Previously,
1297 multi-value tuples would raise an exception and single-value tuples would
1298 be treated as the value they contain, instead.
1299
Martin v. Löwisede77f52006-07-03 13:01:35 +00001300- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1301 even if some data are received.
1302
Martin v. Löwis45482392006-07-03 12:28:58 +00001303- Bug #1267547: Put proper recursive setup.py call into the
1304 spec file generated by bdist_rpm.
1305
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001306- Bug #1514693: Update turtle's heading when switching between
1307 degrees and radians.
1308
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001309- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001310 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001311
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001312- Bug #1514703: Only setup canvas window in turtle when the canvas
1313 is created.
1314
Martin v. Löwis7596e832006-07-01 15:33:37 +00001315- Bug #1513223: .close() of a _socketobj now releases the underlying
1316 socket again, which then gets closed as it becomes unreferenced.

1319 attribute values.
1320
1321- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1322 sgmllib ('[' and ']' were not accepted).
1323
Georg Brandl1be63af2006-06-28 20:23:25 +00001324- Fix a bug in the turtle module's end_fill function.
1325
Brett Cannon53ab5b72006-06-22 16:49:14 +00001326- Bug #1510580: The 'warnings' module improperly required that a Warning
1327 category be either a types.ClassType and a subclass of Warning. The proper
1328 check is just that it is a subclass with Warning as the documentation states.
1329
Georg Brandlad29e632006-06-21 17:45:17 +00001330- The compiler module now correctly compiles the new try-except-finally
1331 statement (bug #1509132).
1332
Neal Norwitz60373cd2006-06-22 06:30:50 +00001333- The wsgiref package is now installed properly on Unix.
1334
Vinay Sajip28e57612006-07-01 10:45:20 +00001335- A bug was fixed in logging.config.fileConfig() which caused a crash on
1336 shutdown when fileConfig() was called multiple times.
1337
Gerhard Häring762fbd32006-07-02 17:48:30 +00001338- The sqlite3 module did cut off data from the SQLite database at the first
1339 null character before sending it to a custom converter. This has been fixed
1340 now.
1341
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001342Extension Modules
1343-----------------
1344
Tim Peters112aad32006-07-19 00:03:19 +00001345- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1346 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1347 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001348
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001349- Assigning None to pointer type fields in ctypes structures possible
1350 overwrote the wrong fields, this is fixed now.
1351
1352- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1353 on non-Windows platforms.
1354
1355- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1356 integer or long, without range checking.
1357
1358- Patch #1517790: It is now possible to use custom objects in the ctypes
1359 foreign function argtypes sequence as long as they provide a from_param
1360 method, no longer is it required that the object is a ctypes type.
1361
1362- The '_ctypes' extension module now works when Python is configured
1363 with the --without-threads option.
1364
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001365- Bug #1513646: os.access on Windows now correctly determines write
1366 access, again.
1367
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001368- Bug #1512695: cPickle.loads could crash if it was interrupted with
1369 a KeyboardInterrupt.
1370
Neal Norwitza12aa882006-07-06 06:45:08 +00001371- Bug #1296433: parsing XML with a non-default encoding and
1372 a CharacterDataHandler could crash the interpreter in pyexpat.
1373
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001374- Patch #1516912: improve Modules support for OpenVMS.
1375
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001376Build
1377-----
1378
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001379- Automate Windows build process for the Win64 SSL module.
1380
Tim Peters32a83612006-07-10 21:08:24 +00001381- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001382 Previously, the slight difference could cause compilation errors of the
1383 'zlib' module on systems with more than one version of zlib.
1384
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001385- The MSI compileall step was fixed to also support a TARGETDIR
1386 with spaces in it.
1387
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001388- Bug #1517388: sqlite3.dll is now installed on Windows independent

Neal Norwitzb15ac312006-06-29 04:10:08 +00001394Tests
1395-----
1396
1397- Call os.waitpid() at the end of tests that spawn child processes in order
1398 to minimize resources (zombies).
1399
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001400Documentation
1401-------------
1402
Nick Coghlan2d792252006-07-06 13:47:18 +00001403- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1404 documentation for the warnings module.
1405
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001406- Patch #1509163: MS Toolkit Compiler no longer available.
1407

1417-----------------
1418
Georg Brandla56b9152006-06-19 06:35:54 +00001419- Patch #1507676: Error messages returned by invalid abstract object operations
1420 (such as iterating over an integer) have been improved and now include the
1421 type of the offending object to help with debugging.
1422
Brett Cannonea3912b2006-06-13 21:46:41 +00001423- Bug #992017: A classic class that defined a __coerce__() method that returned
1424 its arguments swapped would infinitely recurse and segfault the interpreter.
1425
Neal Norwitz909eb122006-06-12 02:13:21 +00001426- Fix the socket tests so they can be run concurrently.
1427
Neal Norwitzb9845e72006-06-12 02:11:18 +00001428- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001429 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001430
Brett Cannon22565aa2006-06-09 22:31:23 +00001431- Bug #532646: object.__call__() will continue looking for the __call__
1432 attribute on objects until one without one is found. This leads to recursion
1433 when you take a class and set its __call__ attribute to an instance of the
1434 class. Originally fixed for classic classes, but this fix is for new-style.
1435 Removes the infinite_rec_3 crasher.
1436
Georg Brandl24250812006-06-09 18:45:48 +00001437- The string and unicode methods startswith() and endswith() now accept
1438 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1439
Brett Cannonde3b0522006-06-08 17:00:45 +00001440- Buffer objects, at the C level, never used the char buffer
1441 implementation even when the char buffer for the wrapped object was
1442 explicitly requested (originally returned the read or write buffer).
1443 Now a TypeError is raised if the char buffer is not present but is
1444 requested.
1445
Georg Brandlddbaa662006-06-04 21:56:52 +00001446- Patch #1346214: Statements like "if 0: suite" are now again optimized
1447 away like they were in Python 2.4.
1448
Georg Brandlb7c8f542006-05-27 12:30:25 +00001449- Builtin exceptions are now full-blown new-style classes instead of
1450 instances pretending to be classes, which speeds up exception handling
1451 by about 80% in comparison to 2.5a2.
1452
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001453- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1454 Unicode 4.1.
1455
Georg Brandlf4ef1162006-05-26 18:03:31 +00001456- Patch #921466: sys.path_importer_cache is now used to cache valid and
1457 invalid file paths for the built-in import machinery which leads to
1458 fewer open calls on startup.
1459
Tim Peters696cf432006-05-24 21:10:40 +00001460- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1461 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1462 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1463 the number of input digits (it was and remains linear-time for bases
1464 2, 4, 8, 16 and 32).
1465
Tim Petersb713ec22006-05-23 18:45:30 +00001466- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1467 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1468 an integer close to ``sys.maxint``. This was repaired by patch
1469 #1335972, which also gives a nice speedup.
1470
Richard Jonescebbefc2006-05-23 18:28:17 +00001471- Patch #1337051: reduced size of frame objects.
1472
1473- PyErr_NewException now accepts a tuple of base classes as its
1474 "base" parameter.
1475
Richard Jones7c88dcc2006-05-23 10:37:38 +00001476- Patch #876206: function call speedup by retaining allocated frame
1477 objects.
1478
Georg Brandl7b90e162006-05-18 07:01:27 +00001479- Bug #1462152: file() now checks more thoroughly for invalid mode
1480 strings and removes a possible "U" before passing the mode to the
1481 C library function.
1482
Neal Norwitz1004a532006-05-15 07:17:23 +00001483- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1484
Neal Norwitz373f0a72006-05-15 07:04:36 +00001485- Bug #1487966: Fix SystemError with conditional expression in assignment
1486
Martin v. Löwis879768d2006-05-11 13:28:43 +00001487- WindowsError now has two error code attributes: errno, which carries
1488 the error values from errno.h, and winerror, which carries the error
1489 values from winerror.h. Previous versions put the winerror.h values
1490 (from GetLastError()) into the errno attribute.
1491
Martin v. Löwis77736712006-05-04 05:51:03 +00001492- Patch #1475845: Raise IndentationError for unexpected indent.
1493
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001494- Patch #1479181: split open() and file() from being aliases for each other.
1495
Tim Peters44bd9862006-06-01 13:49:23 +00001496- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1497 methods were always silently ignored by dictionaries when comparing keys.
1498 They are now passed through (except when using the C API function
1499 ``PyDict_GetItem()``, whose semantics did not change).
1500
1501- Bug #1456209: In some obscure cases it was possible for a class with a
1502 custom ``__eq__()`` method to confuse dict internals when class instances
1503 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1504 No, you don't have any code that did this ;-)

1507-----------------
1508
Trent Mick960a3f82006-06-28 20:30:41 +00001509- Bug #1295808: expat symbols should be namespaced in pyexpat
1510
1511- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1512
Brett Cannon6ee7d012006-06-08 16:23:04 +00001513- Change binascii.hexlify to accept a read-only buffer instead of only a char
1514 buffer and actually follow its documentation.
1515
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001516- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1517
Nick Coghlanc649ec52006-05-29 12:43:05 +00001518- Patch #1478788 (modified version): The functional extension module has
1519 been renamed to _functools and a functools Python wrapper module added.
1520 This provides a home for additional function related utilities that are
1521 not specifically about functional programming. See PEP 309.
1522
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001523- Patch #1493701: performance enhancements for struct module.
1524
Georg Brandl378d5922006-05-17 14:26:50 +00001525- Patch #1490224: time.altzone is now set correctly on Cygwin.
1526
Georg Brandl8d3342b2006-05-16 07:38:27 +00001527- Patch #1435422: zlib's compress and decompress objects now have a
1528 copy() method.
1529
Andrew MacIntyre92913322006-06-13 15:04:24 +00001530- Patch #1454481: thread stack size is now tunable at runtime for thread
1531 enabled builds on Windows and systems with Posix threads support.
1532
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001533- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1534 (up to the system limit of 32K characters).
1535
1536- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1537 As a result, these functions now raise WindowsError instead of OSError.
1538
Tim Peters7a822da2006-05-25 21:50:17 +00001539- ``time.clock()`` on Win64 should use the high-performance Windows
1540 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1541 Windows platforms).
1542
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001543- Calling Tk_Init twice is refused if the first call failed as that
1544 may deadlock.
1545
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001546- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1547 accept it without potentially using an uninitialized pointer.
1548
1549- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1550 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1551 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001552
Gregory P. Smith372b5832006-06-05 18:48:21 +00001553- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001554 [pybsddb project SF patch number 1466734]
1555
Gregory P. Smith372b5832006-06-05 18:48:21 +00001556- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1557 parameter is supplied. [SF pybsddb bug #1477863]
1558
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001559- bsddb: the __len__ method of a DB object has been fixed to return correct
1560 results. It could previously incorrectly return 0 in some cases.
1561 Fixes SF bug 1493322 (pybsddb bug 1184012).
1562
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001563- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1564 aborts the db transaction safely when a modifier callback fails.
1565 Fixes SF python patch/bug #1408584.
1566
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001567- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001568 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001569 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1570 database calls that would previously deadlock. [SF python bug #775414]
1571
Vinay Sajip28e57612006-07-01 10:45:20 +00001572- Patch #1446489: add support for the ZIP64 extensions to zipfile.

1581 functions.
1582
Martin v. Löwis3798da02006-06-17 18:44:27 +00001583- Patch #812986: Update turtle output even if not tracing.

Vinay Sajip28e57612006-07-01 10:45:20 +00001585- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001586 Tkinter.BaseWidget.
1587
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001588- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.

1591 classes.
1592
Georg Brandl83cc0d02006-06-14 08:50:03 +00001593- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1594 mime.types file for determining MIME types.
1595
Georg Brandl2605ca82006-06-14 06:08:31 +00001596- Bug #1339007: Shelf objects now don't raise an exception in their
1597 __del__ method when initialization failed.
1598
Martin v. Löwisd8251432006-06-14 05:21:04 +00001599- Patch #1455898: The MBCS codec now supports the incremental mode for
1600 double-byte encodings.
1601
Tim Peters43898b42006-06-14 04:09:25 +00001602- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1603 guarantee that adjacent triples in the return list always describe
1604 non-adjacent blocks. Previously, a pair of matching blocks could end
1605 up being described by multiple adjacent triples that formed a partition
1606 of the matching pair.
1607
Greg Ward0e0c9f42006-06-11 16:24:11 +00001608- Bug #1498146: fix optparse to handle Unicode strings in option help,
1609 description, and epilog.
1610
Greg Wardd1c797e2006-06-11 14:42:41 +00001611- Bug #1366250: minor optparse documentation error.
1612
Greg Ward7f547402006-06-11 00:40:49 +00001613- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1614 clarify docs.
1615
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001616- The wsgiref package has been added to the standard library.
1617
Nick Coghlan676725d2006-06-08 13:54:49 +00001618- The functions update_wrapper() and wraps() have been added to the functools
1619 module. These make it easier to copy relevant metadata from the original
1620 function when writing wrapper functions.
1621
Tim Petersd6a9eef2006-06-05 01:48:21 +00001622- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1623 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001624
Martin v. Löwis3f767792006-06-04 19:36:28 +00001625- Patch #1359618: Speed up charmap encoder by using a trie structure
1626 for lookup.
1627
Tim Petersd609b1a2006-06-02 23:22:51 +00001628- The functions in the ``pprint`` module now sort dictionaries by key
1629 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1630 if and only if its display required more than one line, although that
1631 wasn't documented. The new behavior increases predictability; e.g.,
1632 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1633
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001634- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1635 (thanks for J. J. Lee).
1636
Georg Brandl2b330372006-05-28 20:23:12 +00001637- Patch #1496206: improve urllib2 handling of passwords with respect to
1638 default HTTP and HTTPS ports.
1639
George Yoshidaf3c65de2006-05-28 16:39:09 +00001640- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1641
Bob Ippolito7298f272006-05-23 18:43:47 +00001642- Patch #1281707: speed up gzip.readline.
1643
Georg Brandlb89316f2006-05-17 15:51:16 +00001644- Patch #1180296: Two new functions were added to the locale module:
1645 format_string() to get the effect of "format % items" but locale-aware,
1646 and currency() to format a monetary number with currency sign.
1647
Georg Brandle3a25832006-05-17 14:56:04 +00001648- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1649 and several features added, such as speed and geometry control.
1650
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001651- Patch #1488881: add support for external file objects in bz2 compressed
1652 tarfiles.
1653
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001654- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1655 stdout arguments, making it possible to redirect input and output
1656 for remote debugging.
1657
1658- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1659 a couple of issues, notably handling of long file names using the
1660 GNU LONGNAME extension.
1661
1662- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1663 new flag when ``name`` is already the name of an option flag.
1664
1665- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1666 package.
1667
1668- Patch #1472854: make the rlcompleter.Completer class usable on non-
1669 UNIX platforms.
1670
1671- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1672
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001673- Bug #1472827: correctly escape newlines and tabs in attribute values in
1674 the saxutils.XMLGenerator class.

1710-----------------
1711
Thomas Heller1b046642006-04-18 18:51:06 +00001712- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1713 by converting these apis from macros into exported functions again:
1714
1715 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1716 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1717 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1718 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1719 PyRun_String Py_CompileString
1720
Martin v. Löwis45294a92006-04-18 06:24:08 +00001721- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1722
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001723- All uses of PyStructSequence_InitType have been changed to initialize
1724 the type objects only once, even if the interpreter is initialized
1725 multiple times.
1726
Neal Norwitz61546162006-04-14 05:20:28 +00001727- Bug #1454485, array.array('u') could crash the interpreter. This was
1728 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1729 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1730
1731- Py_UNICODE is unsigned. It was always documented as unsigned, but
1732 due to a bug had a signed value in previous versions.
1733
Tim Peters3a5e8b12006-04-11 01:44:07 +00001734- Patch #837242: ``id()`` of any Python object always gives a positive
1735 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1736 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001737 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001738 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001739
Tim Peters3a5e8b12006-04-11 01:44:07 +00001740 def __hash__(self):
1741 return id(self) # WRONG
1742
1743 because a hash result must be a (short) Python int but it was always
1744 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001745 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001746 was always usable as a hash value before this patch. That's no longer
1747 necessarily so.
1748
1749- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001750 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001751 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001752 #1454844)
1753
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001754- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1755 involving generators that have paused outside of any ``try`` or ``with``
1756 blocks. (In 2.5a1, a paused generator that was part of a reference
1757 cycle could not be garbage collected, regardless of whether it was
1758 paused in a ``try`` or ``with`` block.)

1761-----------------
1762
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001763- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1764 is a macro.
1765
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001766- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1767 fails with an error condition.

Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001769- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1770
1771- Bug #1117761: bsddb.*open() no longer raises an exception when using
1772 the cachesize parameter.
1773
1774- Bug #1149413: bsddb.*open() no longer raises an exception when using
1775 a temporary db (file=None) with the 'n' flag to truncate on open.
1776
1777- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1778 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001779
Armin Rigoa9017c32006-04-19 11:50:27 +00001780- Patch #1062014: AF_UNIX sockets under Linux have a special
1781 abstract namespace that is now fully supported.

Peter Astrand7d1d4362006-07-14 14:04:45 +00001786- Bug #1223937: subprocess.CalledProcessError reports the exit status
1787 of the process using the returncode attribute, instead of
1788 abusing errno.
1789
Tim Peters711bf302006-04-25 03:31:36 +00001790- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1791 a doctest to be skipped (the code is not run, and the expected output
1792 or exception is ignored).
1793
Nick Coghlanda2268f2006-04-24 04:37:15 +00001794- Fixed contextlib.nested to cope with exceptions being raised and
1795 caught inside exit handlers.
1796
Greg Wardab05edc2006-04-23 03:47:58 +00001797- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1798 hex, octal, or binary; add ``append_const`` action; keep going if
1799 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1800 added ``epilog`` for better help generation).
1801
Tim Peters21fbd572006-04-21 21:18:10 +00001802- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1803 called from a thread spawned as a side effect of importing a module.
1804
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001805- The pydoc module now supports documenting packages contained in
1806 .zip or .egg files.
1807
1808- The pkgutil module now has several new utility functions, such
1809 as ``walk_packages()`` to support working with packages that are either
1810 in the filesystem or zip files.
1811
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001812- The mailbox module can now modify and delete messages from
1813 mailboxes, in addition to simply reading them. Thanks to Gregory
1814 K. Johnson for writing the code, and to the 2005 Google Summer of
1815 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001816

1827 Windows. Bug #1469163.
1828
Phillip J. Eby47032112006-04-11 01:07:43 +00001829- The warnings, linecache, inspect, traceback, site, and doctest modules
1830 were updated to work correctly with modules imported from zipfiles or
1831 via other PEP 302 __loader__ objects.

1839
Skip Montanaro262fb922006-04-21 02:31:07 +00001840- The pstats.Stats class accepts an optional stream keyword argument to
1841 direct output to an alternate file-like object.
1842
Anthony Baxter51bcb682006-04-05 14:51:42 +00001843Build
1844-----
1845
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001846- The Makefile now has a reindent target, which runs reindent.py on
1847 the library.
1848
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001849- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001852
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001853- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1854 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001855 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001856 CXX from --with-cxx-main, see description in README.
1857
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001858- Patch #1429775: Link extension modules with the shared libpython.
1859
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001860- Fixed a libffi build problem on MIPS systems.
1861
Tim Peters8931ff12006-05-13 23:28:20 +00001862- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1863 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1864 and "%zu" for unsigned integers of type ``size_t``.
1865
Anthony Baxter51bcb682006-04-05 14:51:42 +00001866Tests
1867-----
1868
Nick Coghlanda2268f2006-04-24 04:37:15 +00001869- test_contextlib now checks contextlib.nested can cope with exceptions
1870 being raised and caught inside exit handlers.
1871
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001872- test_cmd_line now checks operation of the -m and -c command switches
1873
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001874- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1875 it separately and by hand. It also wasn't cleaning up its changes to
1876 the current Decimal context.
1877
Thomas Woutersabd08882006-04-26 15:53:30 +00001878- regrtest.py now has a -M option to run tests that test the new limits of
1879 containers, on 64-bit architectures. Running these tests is only sensible
1880 on 64-bit machines with more than two gigabytes of memory. The argument
1881 passed is the maximum amount of memory for the tests to use.
1882
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001883Tools

1890-------------
1891
Tim Petersb06d28c2006-05-12 01:57:59 +00001892- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1893
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001894- PEP 343: Added Context Types section to the library reference
1895 and attempted to bring other PEP 343 related documentation into
1896 line with the implementation and/or python-dev discussions.
1897
Tim Peters8dc73d22006-04-24 02:03:16 +00001898- Bug #1337990: clarified that ``doctest`` does not support examples
1899 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001902What's New in Python 2.5 alpha 1?
1903=================================
1904
Anthony Baxterebed3f62006-04-03 15:03:44 +00001905*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001906
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001907Core and builtins
1908-----------------
1909
Nick Coghlan43832302006-04-23 17:04:07 +00001910- PEP 338: -m command line switch now delegates to runpy.run_module
1911 allowing it to support modules in packages and zipfiles
1912
Martin v. Löwisc661b882006-04-20 04:54:23 +00001913- On Windows, .DLL is not an accepted file name extension for
1914 extension modules anymore; extensions are only found if they
1915 end in .PYD.
1916
Martin v. Löwisea62d252006-04-03 10:56:49 +00001917- Bug #1421664: sys.stderr.encoding is now set to the same value as
1918 sys.stdout.encoding.
1919
Neal Norwitz92e212f2006-04-03 04:48:37 +00001920- __import__ accepts keyword arguments.
1921
Georg Brandlccadf842006-03-31 18:54:53 +00001922- Patch #1460496: round() now accepts keyword arguments.
1923
Anthony Baxter262c00a2006-03-30 10:53:17 +00001924- Fixed bug #1459029 - unicode reprs were double-escaped.
1925
Hye-Shik Changd478f342006-03-23 12:32:36 +00001926- Patch #1396919: The system scope threads are reenabled on FreeBSD
1927 5.4 and later versions.
1928
Neal Norwitze98ccf62006-03-23 05:39:47 +00001929- Bug #1115379: Compiling a Unicode string with an encoding declaration
1930 now gives a SyntaxError.
1931
Georg Brandlabd1ff82006-03-18 07:59:59 +00001932- Previously, Python code had no easy way to access the contents of a
1933 cell object. Now, a ``cell_contents`` attribute has been added
1934 (closes patch #1170323).
1935
Tim Peterscf79aac2006-03-16 01:14:46 +00001936- Patch #1123430: Python's small-object allocator now returns an arena to
1937 the system ``free()`` when all memory within an arena becomes unused
1938 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1939 freed. Some applications will see a drop in virtual memory size now,
1940 especially long-running applications that, from time to time, temporarily
1941 use a large number of small objects. Note that when Python returns an
1942 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001943 platform C library will in turn return that memory to the operating system.
1944 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001945 appears to be effective at least on Microsoft C and gcc-based systems.
1946 Thanks to Evan Jones for hard work and patience.
1947
Georg Brandl533ff6f2006-03-08 18:09:27 +00001948- Patch #1434038: property() now uses the getter's docstring if there is
1949 no "doc" argument given. This makes it possible to legitimately use
1950 property() as a decorator to produce a read-only property.
1951
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001952- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1953 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1954 of requiring an int or long in slicing and a few other contexts, enabling
1955 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1956
Neal Norwitz995acdf2006-03-07 05:01:00 +00001957- Fixed various bugs reported by Coverity's Prevent tool.
1958
Brett Cannonbf364092006-03-01 04:25:17 +00001959- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1960 new exception base class, BaseException, which has a new message attribute.
1961 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1962 Raising a string exception now raises a DeprecationWarning.
1963
Thomas Woutersfb609f42006-02-28 16:37:25 +00001964- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1965 explicitly relative, using 'from .module import name' to mean 'from the same
1966 package as this module is in. Imports without dots still default to the
1967 old relative-then-absolute, unless 'from __future__ import
1968 absolute_import' is used.
1969
Brett Cannona7446e32006-02-27 23:39:10 +00001970- Properly check if 'warnings' raises an exception (usually when a filter set
1971 to "error" is triggered) when raising a warning for raising string
1972 exceptions.
1973
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001974- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001975 The name was removed from Include/code.h.
1976
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001977- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001978
Guido van Rossum1968ad32006-02-25 22:38:04 +00001979- Patch 1433928:
1980 - The copy module now "copies" function objects (as atomic objects).
1981 - dict.__getitem__ now looks for a __missing__ hook before raising
1982 KeyError.
1983
Tim Peters84ef21c2006-02-28 20:39:06 +00001984- PEP 343: with statement implemented. Needs ``from __future__ import
1985 with_statement``. Use of 'with' as a variable will generate a warning.
1986 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001987 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001988 The following objects have __context__ methods:
1989 - The built-in file type.
1990 - The thread.LockType type.
1991 - The following types defined by the threading module:
1992 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1993 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001994
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001995- Fix the encodings package codec search function to only search
1996 inside its own package. Fixes problem reported in patch #1433198.
1997
1998 Note: Codec packages should implement and register their own
1999 codec search function. PEP 100 has the details.
2000
Tim Peters9ea89d22006-06-04 03:26:02 +00002001- PEP 353: Using ``Py_ssize_t`` as the index type.
2002
2003- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2004 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2005 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2006 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2007 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002008
Neal Norwitzfc76d632006-01-10 06:03:13 +00002009- Patch #1400181, fix unicode string formatting to not use the locale.
2010 This is how string objects work. u'%f' could use , instead of .
2011 for the decimal point. Now both strings and unicode always use periods.
2012
Neal Norwitz671b9e32006-01-09 07:07:12 +00002013- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2014 configure would break checking curses.h.
2015
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002016- Bug #959576: The pwd module is now builtin. This allows Python to be
2017 built on UNIX platforms without $HOME set.
2018
Neal Norwitzc10978f2005-12-19 06:07:16 +00002019- Bug #1072182, fix some potential problems if characters are signed.
2020
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002021- Bug #889500, fix line number on SyntaxWarning for global declarations.
2022
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002023- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2024
Neal Norwitze7214a12005-12-18 05:03:17 +00002025- Support for converting hex strings to floats no longer works.
2026 This was not portable. float('0x3') now raises a ValueError.
2027
Barry Warsaw2a38a862005-12-18 01:27:35 +00002028- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002029 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002030 is now displayed in interactive prompt banner.
2031
Georg Brandlfa166682005-12-17 21:45:17 +00002032- Implementation of PEP 341 - Unification of try/except and try/finally.
2033 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002034 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002035
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002036- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2037 now encodes backslash correctly.
2038
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002039- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2040
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002041- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002042 and long longs.
2043
Neal Norwitz67715f02005-11-09 06:59:35 +00002044- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002045 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002046 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002047
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002048- Replaced most Unicode charmap codecs with new ones using the
2049 new Unicode translate string feature in the builtin charmap
2050 codec; the codecs were created from the mapping tables available
2051 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2052 encodings now include a mapping for the Apple logo)

Tim Peterse3547fd2005-12-16 23:13:57 +00002054- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002055
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002056- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002057
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002058- A new AST parser implementation was completed. The abstract
2059 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002060 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002061
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002062- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002063 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2064
Neal Norwitz708e51a2005-10-03 04:48:15 +00002065- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2066
Neal Norwitz11bd1192005-10-03 00:54:56 +00002067- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2068 Provide a warning when a directory is passed on the command line.
2069
Neal Norwitz40d37812005-10-02 01:48:49 +00002070- Fix segfault with invalid coding.
2071
2072- SF bug #772896: unknown encoding results in MemoryError.
2073
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002074- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002075 supported a __len__() method which evaluated to False when the iterator
2076 was empty.
2077
Guido van Rossum630db602005-09-20 18:49:54 +00002078- On 64-bit platforms, when __len__() returns a value that cannot be
2079 represented as a C int, raise OverflowError.
2080
Skip Montanarof8948ca2005-09-19 03:54:46 +00002081- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002082 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002083
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002084- SF bug #893549: parsing keyword arguments was broken with a few format
2085 codes.
2086
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002087- Changes donated by Elemental Security to make it work on AIX 5.3
2088 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2089 bug #105470: test_pwd fails on 64bit system (Opteron).
2090
Guido van Rossum539c6622005-09-14 17:49:54 +00002091- Changes donated by Elemental Security to make it work on HP-UX 11 on
2092 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2093
Georg Brandl4550b8d2005-08-26 06:43:52 +00002094- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002095 (fixes bug #1119418).
2096
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002097- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2098
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002099- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2100 exceptions that cause a function to exit.
2101
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002102- The implementation of set() and frozenset() was revised to use its
2103 own internal data structure. Memory consumption is reduced by 1/3
2104 and there are modest speed-ups as well. The API is unchanged.
2105
Tim Petersde7990b2005-07-17 23:45:23 +00002106- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2107
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002108- SF bug #1229429: PyObject_CallMethod failed to decrement some
2109 reference counts in some error exit cases.
2110
Tim Petersecc6e6a2005-07-10 22:30:55 +00002111- SF bug #1185883: Python's small-object memory allocator took over
2112 a block managed by the platform C library whenever a realloc specified
2113 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002114 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002115 portable way to copy data from the C-managed block into Python's
2116 small-object space without risking a memory fault. Python's small-object
2117 realloc now leaves such blocks under the control of the platform C
2118 realloc.
2119
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002120- SF bug #1232517: An overflow error was not detected properly when
2121 attempting to convert a large float to an int in os.utime().
2122
Raymond Hettinger3296e692005-06-29 23:29:56 +00002123- SF bug #1224347: hex longs now print with lowercase letters just
2124 like their int counterparts.
2125
Michael W. Hudson188d4362005-06-20 16:52:57 +00002126- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2127 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2128 interpreter states; back out that fix and do a better job (see
2129 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2130 for a longer write-up of the problem).
2131
Michael W. Hudsondf888462005-06-03 14:41:55 +00002132- SF patch #1180995: marshal now uses a binary format by default when
2133 serializing floats.
2134
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002135- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2136 the routines that promise to produce IEEE 754 binary representations
2137 of floats now simply copy bytes around.
2138
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002139- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2140 278.
2141
Brett Cannonc3647ac2005-04-26 03:45:26 +00002142- patch #1109424: int, long, float, complex, and unicode now check for the
2143 proper magic slot for type conversions when subclassed. Previously the
2144 magic slot was ignored during conversion. Semantics now match the way
2145 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002146 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002147 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002148 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002149
Barry Warsawc8d907c2005-04-19 23:43:40 +00002150- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2151 NULL, now raise an AttributeError when attempting to set or delete the
2152 attribute. Previously a TypeError was raised, but this was inconsistent
2153 with the equivalent pure-Python implementation.
2154
Michael W. Hudson774479c2005-04-18 08:46:17 +00002155- It is now safe to call PyGILState_Release() before
2156 PyEval_InitThreads() (note that if there is reason to believe there
2157 are multiple threads around you still must call PyEval_InitThreads()
2158 before using the Python API; this fix is for extension modules that
2159 have no way of knowing if Python is multi-threaded yet).
2160
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002161- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2162 disabled caused a crash.
2163
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002164- Bug #1165306: instancemethod_new allowed the creation of a method
2165 with im_class == im_self == NULL, which caused a crash when called.
2166
Tim Petersecc6e6a2005-07-10 22:30:55 +00002167- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002168 fixes the crash seen in bug #1165761
2169
Raymond Hettinger96229b12005-03-11 06:49:40 +00002170- Added two new builtins, any() and all().
2171
Brett Cannon409d8f22005-03-05 06:47:57 +00002172- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002173 (e.g., ``class C(): pass`` is no longer a syntax error).
2174 Patch #1176012 added support to the 'parser' module and 'compiler' package
2175 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002176
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002177- Patch #1115086: Support PY_LONGLONG in structmember.
2178
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002179- Bug #1155938: new style classes did not check that __init__() was
2180 returning None.
2181
Tim Petersecc6e6a2005-07-10 22:30:55 +00002182- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002183 ('\') with a specific error message.
2184
Martin v. Löwisff232d72005-03-03 09:24:38 +00002185- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2186
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002187- Bug #1124295: the __name__ attribute of file objects was
2188 inadvertently made inaccessible in restricted mode.
2189
Tim Petersecc6e6a2005-07-10 22:30:55 +00002190- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002191 an ferror() call.
2192
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002193- min() and max() now support key= arguments with the same meaning as in
2194 list.sort().
2195
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002196- The peephole optimizer now performs simple constant folding in expressions:
2197 (2+3) --> (5).
2198
Raymond Hettingera422c342005-01-11 03:03:27 +00002199- set and frozenset objects can now be marshalled. SF #1098985.
2200
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002201- Bug #1077106: Poor argument checking could cause memory corruption
2202 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002203
Jeremy Hyltonab630502005-02-04 18:44:06 +00002204- The parser did not complain about future statements in illegal
2205 positions. It once again reports a syntax error if a future
2206 statement occurs after anything other than a doc string.
2207
Neil Schemenauercf52c072005-08-12 17:34:58 +00002208- Change the %s format specifier for str objects so that it returns a
2209 unicode instance if the argument is not an instance of basestring and
2210 calling __str__ on the argument returns a unicode instance.
2211
Tim Petersf4e69282006-02-27 17:15:31 +00002212- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2213 current thread state when the auto-GIL-state machinery knows about
2214 it (since the thread state is being deleted, continuing to remember it
2215 can't help, but can hurt if another thread happens to get created with
2216 the same thread id).
2217
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002218Extension Modules
2219-----------------
2220

Tim Petersc9d78aa2006-03-26 23:27:58 +00002233 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00002234 util, whatsound, whrandom, zmod
2235
2236- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2237
2238- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002239 is deprecated. The undocumented re.engine variable no longer exists.
2240
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002241- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2242 SS2 (single-shift 2) escape sequences correctly.
2243
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002244- The unicodedata module was updated to the 4.1 version of the Unicode
2245 database. The 3.2 version is still available as unicodedata.db_3_2_0
2246 for applications that require this specific version (such as IDNA).
2247
Neal Norwitzb62c4332006-03-04 18:35:47 +00002248- The timing module is no longer built by default. It was deprecated
2249 in PEP 4 in Python 2.0 or earlier.
2250
Guido van Rossum1968ad32006-02-25 22:38:04 +00002251- Patch 1433928: Added a new type, defaultdict, to the collections module.
2252 This uses the new __missing__ hook behavior added to dict (see above).
2253
Georg Brandldbd83392006-02-20 09:42:33 +00002254- Bug #854823: socketmodule now builds on Sun platforms even when
2255 INET_ADDRSTRLEN is not defined.
2256
Georg Brandlf4f44152006-02-18 22:29:33 +00002257- Patch #1393157: os.startfile() now has an optional argument to specify
2258 a "command verb" to invoke on the file.
2259
Neal Norwitz082b2df2006-02-07 07:04:46 +00002260- Bug #876637, prevent stack corruption when socket descriptor
2261 is larger than FD_SETSIZE.
2262
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00002263- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
2264 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
2265 mmap.mmap(0, size) should not be used on Windows for anonymous memory.

2268 than the system default domain.
2269
Martin v. Löwis14694662006-02-03 12:54:16 +00002270- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2271 are reported, the limit on path name lengths is removed, and stat reports
2272 WindowsError now (instead of OSError).
2273
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002274- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

Michael W. Hudson8137bea2005-07-27 20:24:40 +00002348- Patch #1231069: The fcntl.ioctl function now uses the 'I' code for
2349 the request code argument, which results in more C-like behaviour
2350 for large or negative values.
2351
Tim Petersecc6e6a2005-07-10 22:30:55 +00002352- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

2367
Raymond Hettinger984f9bb2005-03-09 16:38:48 +00002368- operator.itemgetter() and operator.attrgetter() now support retrieving

Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002392- the cPickle module no longer accepts the deprecated None option in the
2393 args tuple returned by __reduce__().
2394
Raymond Hettingerb2594052004-12-05 09:25:51 +00002395- itertools.islice() now accepts None for the start and step arguments.
2396 This allows islice() to work more readily with slices:
2397 islice(s.start, s.stop, s.step)
2398
Skip Montanaro0af3ade2005-01-13 04:12:31 +00002399- datetime.datetime() now has a strptime class method which can be used to

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002408- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2409 been renamed to have only a single underscore prefix. This was done to
2410 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002411
Nick Coghlan43832302006-04-23 17:04:07 +00002412- PEP 338: new module runpy defines a run_module function to support
2413 executing modules which provide access to source code or a code object
2414 via the PEP 302 import mechanisms.
2415
Anthony Baxter93f5b932006-04-03 08:05:07 +00002416- The email module's parsedate_tz function now sets the daylight savings
2417 flag to -1 (unknown) since it can't tell from the date whether it should

2424 in attribute values.
2425
Anthony Baxterc51ee692006-04-01 00:57:31 +00002426- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002427 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002428 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002429 module will not be built.
2430
Tim Petersc17976e2006-04-01 00:26:53 +00002431- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2432 aren't officially supported here, and trying to use them will probably
2433 raise an exception some day. But dicts have been allowed, and "mostly
2434 worked", so support for them won't go away without warning.
2435
Georg Brandl338ef7d2006-03-31 18:42:16 +00002436- Bug #1445068: getpass.getpass() can now be given an explicit stream
2437 argument to specify where to write the prompt.
2438
Georg Brandl22ec80b2006-03-31 18:25:44 +00002439- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2446
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002447- Queue.Queue objects now support .task_done() and .join() methods
2448 to make it easier to monitor when daemon threads have completed
2449 processing all enqueued tasks. Patch #1455676.
2450

2454
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002455- email 4.0 package now integrated. This is largely the same as the email 3.0
2456 package that was included in Python 2.3, except that PEP 8 module names are
2457 now used (e.g. mail.message instead of email.Message). The MIME classes
2458 have been moved to a subpackage (e.g. email.mime.text instead of
2459 email.MIMEText). The old names are still supported for now. Several
2460 deprecated Message methods have been removed and lots of bugs have been
2461 fixed. More details can be found in the email package documentation.
2462
Walter Dörwald40108c92006-03-27 08:15:44 +00002463- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2464 (a subclass of tuple) that provides incremental decoders and encoders
2465 (a way to use stateful codecs without the stream API). Python functions
2466 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2467 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2468 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002469
Walter Dörwald067db482006-03-15 22:17:27 +00002470- Patch #1359365: Calling next() on a closed StringIO.String object raises
2471 a ValueError instead of a StopIteration now (like file and cString.String do).
2472 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2473 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002474
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002475- A regrtest option -w was added to re-run failed tests in verbose mode.

2481 grew an optional 'generation' argument.
2482
Martin v. Löwisfbab90e2006-03-05 13:36:04 +00002483- A library msilib to generate Windows Installer files, and a distutils

2485
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002486- PEP 343: new module contextlib.py defines decorator @contextmanager
2487 and helpful context managers nested() and closing().
2488
Martin v. Löwis415ed932006-02-27 19:56:30 +00002489- The compiler package now supports future imports after the module docstring.
2490

2493
Georg Brandlc98eeed2006-02-19 14:57:47 +00002494- Patch #1215184: FileInput now can be given an opening hook which can

Martin v. Löwis3e865952006-01-24 15:51:21 +00002523 specifications, raises IOErrors when proxies for unsupported protocols
2524 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00002547 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2548 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2549 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2550 Ronald L. Rivest offered this advice for Python:
2551
2552 "The consensus of researchers in this area (at least as
2553 expressed at the NIST Hash Function Workshop 10/31/05),
2554 is that SHA-256 is a good choice for the time being, but
2555 that research should continue, and other alternatives may
2556 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002557
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002558- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandlb9256022005-08-24 18:46:39 +00002604- Patch #1062060: urllib.urlretrieve() now raises a new exception, named
2605 ContentTooShortException, when the actually downloaded size does not
2606 match the Content-Length header.
2607
Martin v. Löwis0a5d4a22005-08-24 14:55:22 +00002608- Bug #1121494: distutils.dir_utils.mkpath now accepts Unicode strings.

2611 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002612 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002613

2635 to W3C name (404 -> 'Not Found'). RFE #1216944.
2636
Georg Brandl9e43acf2005-07-04 17:16:07 +00002637- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2638 as this can cause problems with apps closing all file descriptors.

Raymond Hettingerda99d1c2005-06-21 07:43:58 +00002650- The tokenize module now detects and reports indentation errors.
2651 Bug #1224621.
2652
Raymond Hettinger68c04532005-06-10 11:05:19 +00002653- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002654 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002655 the generate_tokens() function now accepts a callable argument that
2656 terminates by raising StopIteration.
2657
Georg Brandl9166e1a2005-06-04 09:20:03 +00002658- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2659
Georg Brandl268e61c2005-06-03 14:28:50 +00002660- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2661 component of the path.
2662
Skip Montanaro174dd222005-05-14 20:54:16 +00002663- Patch #1120353: The xmlrpclib module provides better, more transparent,
2664 support for datetime.{datetime,date,time} objects. With use_datetime set
2665 to True, applications shouldn't have to fiddle with the DateTime wrapper
2666 class at all.
2667
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002668- distutils.commands.upload was added to support uploading distribution
2669 files to PyPI.
2670
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002671- distutils.commands.register now encodes the data as UTF-8 before posting
2672 them to PyPI.
2673
Raymond Hettinger267b8682005-03-27 10:47:39 +00002674- decimal operator and comparison methods now return NotImplemented
2675 instead of raising a TypeError when interacting with other types. This
2676 allows other classes to implement __radd__ style methods and have them
2677 work as expected.
2678
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002679- Bug #1163325: Decimal infinities failed to hash. Attempting to
2680 hash a NaN raised an InvalidOperation instead of a TypeError.
2681
Tim Petersecc6e6a2005-07-10 22:30:55 +00002682- Patch #918101: Add tarfile open mode r|* for auto-detection of the

2716
Guido van Rossumd0641422005-02-03 15:01:24 +00002717- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2718 disables recursive traversal through instance attributes, which can
2719 be exploited in various ways.
2720
Tim Peterse3547fd2005-12-16 23:13:57 +00002721- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002722 flags on the HTTP listening socket.
2723
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002724- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2725 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2726
Fred Drakefbdeaad2006-07-29 16:56:15 +00002727- Patches #893642, #1039083: add allow_none, encoding arguments to
2728 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002729
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002730- Bug #1110478: Revert os.environ.update to do putenv again.
2731
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002732- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2733
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002734- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2735
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002736- Enhancements to the csv module:
2737
2738 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002739 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002740 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002741 + Dialect parameter parsing has been re-implemented to improve error
2742 reporting.
2743 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2744 dictates.
2745 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002746 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002747 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002748 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2749 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002750 + reader now allows \r characters to be quoted (previously it only allowed
2751 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002752 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002753 + Dialect classes passed to the module are no longer instantiated by
2754 the module before being parsed (the former validation scheme required
2755 this, but the mechanism was unreliable).
2756 + The dialect registry now contains instances of the internal
2757 C-coded dialect type, rather than references to python objects.
2758 + the internal c-coded dialect type is now immutable.
2759 + register_dialect now accepts the same keyword dialect specifications
2760 as the reader and writer, allowing the user to register dialects
2761 without first creating a dialect class.
2762 + a configurable limit to the size of parsed fields has been added -
2763 previously, an unmatched quote character could result in the entire
2764 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002765 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002766 the parser field size limit (returning the former limit). The initial
2767 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002768 + A line_num attribute has been added to the reader object, which tracks
2769 the number of lines read from the source iterator. This is not
2770 the same as the number of records returned, as records can span
2771 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002772 + reader and writer objects were not being registered with the cyclic-GC.
2773 This has been fixed.
2774
Brett Cannone6539c42005-01-08 02:43:53 +00002775- _DummyThread objects in the threading module now delete self.__block that is
2776 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2777 lock primitives tend to be limited in number and thus should not be wasted on
2778 a _DummyThread object. Fixes bug #1089632.
2779
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002780- The imghdr module now detects Exif files.
2781
Raymond Hettinger6065d322004-12-20 23:51:53 +00002782- StringIO.truncate() now correctly adjusts the size attribute.
2783 (Bug #951915).
2784
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002785- locale.py now uses an updated locale alias table (built using
2786 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2787 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002788 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002789
Raymond Hettinger3557f422004-12-07 12:02:02 +00002790- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2791
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002792- the pickle module no longer accepts the deprecated None option in the
2793 args tuple returned by __reduce__().
2794
Brett Cannon84667c02004-12-07 03:25:18 +00002795- optparse now optionally imports gettext. This allows its use in setup.py.
2796
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002797- the pickle module no longer uses the deprecated bin parameter.
2798
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002799- the shelve module no longer uses the deprecated binary parameter.
2800
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002801- the pstats module no longer uses the deprecated ignore() method.
2802
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002803- the filecmp module no longer uses the deprecated use_statcache argument.
2804
Raymond Hettinger664347b2004-12-04 21:21:53 +00002805- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2806 extended or overridden by subclasses. Formerly, the subclassed method would
2807 be ignored by the rest of the module. (Bug #1078905).
2808
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002809- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002810 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002811
Walter Dörwald36733692004-12-22 12:50:50 +00002812- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2813 once when a size argument is given. This prevents a buffer overflow in the
2814 tokenizer with very long source lines.
2815
Barry Warsaw538561e2006-01-01 21:48:54 +00002816- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2817 immediately after creating the object, without any intervening
2818 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002819
Skip Montanaro05885812005-01-16 20:48:27 +00002820- The reconvert.quote function can now emit triple-quoted strings. The
2821 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002822
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002823- ``UserString.MutableString`` now supports negative indices in
2824 ``__setitem__`` and ``__delitem__``
2825
Greg Ward40407942005-03-05 02:53:17 +00002826- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2827 correctly.
2828
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002829- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2830 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2831 character even if the user has passed a size parameter to get a proper
2832 line ending. Remove the special handling of a "\r\n" that has been split
2833 between two lines.
2834
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002835- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2836 about illegal code points. The codec now supports PEP 293 style error
2837 handlers.
2838
Walter Dörwald78a78b02005-09-01 12:04:29 +00002839- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002840 from the input stream, so that the output is a byte string in the correct
2841 encoding instead of a unicode string.

Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002843- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2844 considering it exactly like a '*'.
2845
Walter Dörwald007f8df2005-10-09 19:42:27 +00002846- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2847 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002848
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002849- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2850
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002851- Patch #1413711: Certain patterns of differences were making difflib
2852 touch the recursion limit.
2853
Walter Dörwald58917a62006-03-31 15:26:22 +00002854- Bug #947906: An object oriented interface has been added to the calendar
2855 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002856 called as a script (e.g. via ``python -mcalendar``). Localized month and
2857 weekday names can be ouput (even if an exotic encoding is used) using
2858 special classes that use unicode.

2862
Neal Norwitz602d3392006-03-31 08:21:40 +00002863- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2864 by using -mieee gcc option.
2865

2867
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002868- Build support for Win64-AMD64 was added.
2869
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002870- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2871
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002872- Patch #881820: look for openpty and forkpty also in libbsd.
2873
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002874- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2875 The zlib module is now builtin on Windows.
2876
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002877- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2878
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002879- Bug #1189330: configure did not correctly determine the necessary
2880 value of LINKCC if python was built with GCC 4.0.
2881
Trent Mick8321b422005-07-26 02:29:21 +00002882- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2883 vulnerability in zlib 1.2.1 and 1.2.2.
2884
Brett Cannon08cd5982005-04-24 22:26:38 +00002885- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2886 flags that change binary compatibility. Changes were also made to
2887 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002888 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002889
Bob Ippolitoed233462005-03-29 13:47:59 +00002890- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2891 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2892 no longer exists). This configure patch makes things right.
2893
Martin v. Löwise2713be2005-03-08 15:03:08 +00002894- Bug #1158607: Build with --disable-unicode again.
2895
Brett Cannon46d96232005-02-16 00:07:19 +00002896- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2897 defined. Discovered as a result of not being able to build on OS X.
2898
Brett Cannon516592f2004-12-07 00:42:59 +00002899- setup.py now uses the directories specified in LDFLAGS using the -L option
2900 and in CPPFLAGS using the -I option for adding library and include
2901 directories, respectively, for compiling extension modules against. This has
2902 led to the core being compiled using the values in CPPFLAGS. It also removes
2903 the need for the special-casing of both DarwinPorts and Fink for darwin since
2904 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2905 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2906 Fink, ``-I/opt/local/include`` for DarwinPorts).
2907
Brett Cannon43802422005-02-10 20:48:03 +00002908- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2909 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2910 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2911 Closes bug #1096244. Thanks Gregory Bond.

2914-----
2915
Tim Petersc9d78aa2006-03-26 23:27:58 +00002916- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2917 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2918 is obtained via the ``PyObject_`` family, it must be released via the
2919 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2920 always been officially true, but when Python's small-object allocator was
2921 introduced, an attempt was made to cater to a few extension modules
2922 discovered at the time that obtained memory via ``PyObject_New`` but
2923 released it via ``PyMem_DEL``. It's years later, and if such code still
2924 exists it will fail now (probably with segfaults, but calling wrong
2925 low-level memory management functions can yield many symptoms).
2926
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002927- Added a C API for set and frozenset objects.
2928

2930
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002931- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2932 mapping argument now. This string is used as a mapping table. Byte values
2933 greater than the length of the string and 0xFFFE are treated as undefined
2934 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002941
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002942- Patch #1276356: New resource "urlfetch" is implemented. This enables
2943 even impatient people to run tests that require remote files.
