710
Neal Norwitz0bcafac2006-09-11 08:51:17 +0000711- Make _PyGILState_NoteThreadState() static, it was not used anywhere
712 outside of pystate.c and should not be necessary.
713
Brett Cannon19d76c52006-09-09 07:18:44 +0000714- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This

850Core and builtins
851-----------------
852
Neal Norwitz24b6f202006-09-05 04:43:56 +0000853- Fix infinite recursion when subclassing long and overriding __hash__.
854
855- Fix concatenation (+=) of long strings.
856
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000857- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000858 compared equal or unequal to a string and a UnicodeDecodeError
859 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000860
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000861 Instead, the equal (==) and unequal (!=) comparison operators will
862 now issue a UnicodeWarning and interpret the two objects as
863 unequal. The UnicodeWarning can be filtered as desired using
864 the warning framework, e.g. silenced completely, turned into an
865 exception, logged, etc.
866
867 Note that compare operators other than equal and unequal will still
868 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000869

877
878- Patch #1538606, Fix __index__() clipping. There were some problems
879 discovered with the API and how integers that didn't fit into Py_ssize_t
880 were handled. This patch attempts to provide enough alternatives
881 to effectively use __index__.
882
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000883- Bug #1536021: __hash__ may now return long int; the final hash
884 value is obtained by invoking hash on the long int.
885
Thomas Hellerab1049c2006-08-08 17:37:00 +0000886- Bug #1536786: buffer comparison could emit a RuntimeWarning.

Neal Norwitz4ffedad2006-08-04 04:58:47 +0000894- Bug #1191458: tracing over for loops now produces a line event
895 on each iteration. Fixing this problem required changing the .pyc
896 magic number. This means that .pyc files generated before 2.5c1
897 will be regenerated.
898
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000899- Bug #1333982: string/number constants were inappropriately stored
900 in the byte code and co_consts even if they were not used, ie
901 immediately popped off the stack.
902
Georg Brandle9462c72006-08-04 18:03:37 +0000903- Fixed a reference-counting problem in property().

906Library
907-------
908
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000909- Fix a bug in the ``compiler`` package that caused invalid code to be
910 generated for generator expressions.
911
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000912- The distutils version has been changed to 2.5.0. The change to
913 keep it programmatically in sync with the Python version running
914 the code (introduced in 2.5b3) has been reverted. It will continue
915 to be maintained manually as static string literal.
916
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000917- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000918 and this cannot be converted to the required C type, an exception is
919 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000920 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000921
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000922- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000923 an exception.
924
Tim Peterscbdd3502006-09-05 01:47:53 +0000925- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000926 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000927 workarounds for clocks with low resolution, to stop the code yielding
928 duplicate UUIDs.
929
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000930- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
931 before raising SystemExit, allowing IDLE to honor quit() and exit().
932
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000933- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
934
Georg Brandl7a1af772006-08-14 21:55:28 +0000935- Patch #1536071: trace.py should now find the full module name of a
936 file correctly even on Windows.
937
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000938- logging's atexit hook now runs even if the rest of the module has
939 already been cleaned up.
940
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000941- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000942
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000943- Bug #1531405, format_exception no longer raises an exception if
944 str(exception) raised an exception.
945
Neil Schemenauer06ded092006-08-04 16:20:30 +0000946- Fix a bug in the ``compiler`` package that caused invalid code to be
947 generated for nested functions.

Georg Brandl3335a7a2006-08-14 21:42:55 +0000957- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
958 raises the correct exceptions.
959
Thomas Heller1ce433e2006-08-14 16:20:04 +0000960- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
961 '-no-stack-protector' compiler flag for OpenBSD has been removed.
962
Thomas Heller86720042006-08-14 11:17:48 +0000963- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
964 uses the _as_parameter_ attribute when objects are passed to foreign
965 function calls. The ctypes version number was changed to 1.0.1.
966
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000967- Bug #1530559, struct.pack raises TypeError where it used to convert.
968 Passing float arguments to struct.pack when integers are expected
969 now triggers a DeprecationWarning.
970
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000971
972Tests

993-----
994
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +0000995- Bug #1535502, build _hashlib on Windows, and use masm assembler
996 code in OpenSSL.
997
Thomas Hellerdb7b4432006-08-04 19:49:31 +0000998- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.
999
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001000- Bug #1530448, ctypes build failure on Solaris 10 was fixed.
Thomas Heller17984892006-08-04 18:57:34 +00001001
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001002
Tim Peters4643c2f2006-08-10 22:45:34 +00001003C API
1004-----
1005
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001006- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1007
Tim Peters4643c2f2006-08-10 22:45:34 +00001008- Bug #1069160. Internal correctness changes were made to
1009 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1010 the documentation was changed to state that the return value
1011 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001014What's New in Python 2.5 beta 3?
1015================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001016
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001017*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001018
1019Core and builtins
1020-----------------
1021
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001022- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001023 returned a long (see PEP 353).
1024
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001025- Bug #1515471: string.replace() accepts character buffers again.
1026
Neal Norwitz07aadb12006-07-30 06:55:48 +00001027- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1028 This provides the proper warning for struct.pack().
1029 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1030
Neal Norwitz0d62a062006-07-30 06:53:31 +00001031- Patch #1531113: Fix augmented assignment with yield expressions.
1032 Also fix a SystemError when trying to assign to yield expressions.
1033
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001034- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1035 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1036 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1037 excessive filesystem operations during imports.
1038
Tim Petersbc24eee2006-07-27 01:14:53 +00001039- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1040 operations on signed longs that are formally undefined by C.
1041 Unfortunately, at least one compiler now cares about that, so complicated
1042 the code to make that compiler happy again.
1043
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001044- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1045
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001046- Patch #1232023: Stop including current directory in search
1047 path on Windows.
1048
Neal Norwitze1fdb322006-07-21 05:32:28 +00001049- Fix some potential crashes found with failmalloc.
1050
Neal Norwitze7563102006-07-17 01:00:16 +00001051- Fix warnings reported by Klocwork's static analysis tool.
1052
Neal Norwitz84be93b2006-07-16 01:50:38 +00001053- Bug #1512814, Fix incorrect lineno's when code within a function
1054 had more than 255 blank lines.
1055
Georg Brandl9dceedb2006-07-12 15:31:17 +00001056- Patch #1521179: Python now accepts the standard options ``--help`` and
1057 ``--version`` as well as ``/?`` on Windows.
1058
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001059- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001060 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001061 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001062
Tim Peters112aad32006-07-19 00:03:19 +00001063- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001064 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001065 new ``sys._current_frames()`` returns a dictionary with one entry,
1066 mapping the faux "thread id" 0 to the current frame.
1067
Ronald Oussoren3075e162006-07-25 20:28:55 +00001068- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001069
Ronald Oussoren3075e162006-07-25 20:28:55 +00001070
Neal Norwitza1f10902006-07-12 07:28:29 +00001071Library
1072-------
1073
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001074- Correction of patch #1455898: In the mbcs decoder, set final=False
1075 for stream decoder, but final=True for the decode function.
1076
Georg Brandl07fec3a2006-08-01 18:49:24 +00001077- os.urandom no longer masks unrelated exceptions like SystemExit or
1078 KeyboardInterrupt.
1079
Tim Peters4643c2f2006-08-10 22:45:34 +00001080- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001081 shutil.copytree on Windows
1082
Georg Brandle34ac7c2006-07-30 11:07:23 +00001083- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1084 refers to file descriptors, not file objects.
1085
Tim Peterscbdd3502006-09-05 01:47:53 +00001086- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001087 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001088 #1513611, and probably others.
1089
Georg Brandledd9b0d2006-07-29 09:33:26 +00001090- Bug #1441397: The compiler module now recognizes module and function
1091 docstrings correctly as it did in Python 2.4.
1092
Tim Peters6f681472006-07-27 23:44:37 +00001093- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1094 lost that tests are sorted by name before being run. This rarely
1095 matters for well-written tests, but can create baffling symptoms if
1096 side effects from one test to the next affect outcomes. ``DocTestFinder``
1097 has been changed to sort the list of tests it returns.
1098
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001099- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001100 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001101
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001102- Bug #978833: Really close underlying socket in _socketobject.close.
1103
Georg Brandldb232dc2006-08-20 13:15:43 +00001104- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1105 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001106
Georg Brandlcf0c1722006-07-26 07:23:32 +00001107- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1108 to recursive calls and call it with the failing package name.
1109
Martin v. Löwis0b483032006-07-25 09:53:12 +00001110- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1111
Georg Brandlc13c34c2006-07-24 14:09:56 +00001112- Patch #1515343: Fix printing of deprecated string exceptions with a
1113 value in the traceback module.
1114
Greg Ward48fae7a2006-07-23 16:05:51 +00001115- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1116
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001117- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1118
Brett Cannoncaebe222006-07-18 04:41:36 +00001119- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1120 argument tuple. For arguments where zero is illegal, the value is forced to
1121 the minimum value that is correct. This is to support an undocumented but
1122 common way people used to fill in inconsequential information in the time
1123 tuple pre-2.4.
1124
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001125- Patch #1220874: Update the binhex module for Mach-O.
1126
Barry Warsawb110bad2006-07-21 14:51:07 +00001127- The email package has improved RFC 2231 support, specifically for
1128 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1129 (name*0=<blah>) parameter continuations. This may change the types of
1130 values returned from email.message.Message.get_param() and friends.
1131 Specifically in some cases where non-encoded continuations were used,
1132 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1133 will just return the string (since non-encoded continuations don't have
1134 charset and language parts).
1135
1136 Also, whereas % values were decoded in all parameter continuations, they are
1137 now only decoded in encoded parameter parts.
1138
Ronald Oussoren3075e162006-07-25 20:28:55 +00001139- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1140
1141- Bug #1517996: IDLE now longer shows the default Tk menu when a
1142 path browser, class browser or debugger is the frontmost window on MacOS X
1143
Barry Warsaw00decd72006-07-27 23:43:15 +00001144- Patch #1520294: Support for getset and member descriptors in types.py,
1145 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1146 of an object against these built-in types and more importantly, for getting
1147 their docstrings printed in the interactive interpreter's help() function.

1151-----------------
1152
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001153- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1154 a socket operation on a socket with a timeout, the exception will be
1155 caught correctly. Previously, the exception was not caught.
1156
Thomas Heller1393d6a2006-07-28 21:43:20 +00001157- Patch #1529514: The _ctypes extension is now compiled on more
1158 openbsd target platforms.
1159
Tim Peters9cab5932006-07-28 00:30:00 +00001160- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1161 a memory leak, affecting pickles and deep copies.
1162
Tim Petersbc24eee2006-07-27 01:14:53 +00001163- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001164 Paul Eggert.
1165
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001166- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1167
Thomas Hellerce049a02006-07-14 17:51:14 +00001168- Patch #1521817: Index range checking on ctypes arrays containing
1169 exactly one element enabled again. This allows iterating over these
1170 arrays, without the need to check the array size before.
1171
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001172- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001173 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001174 /dev/null in certain cases; this is now fixed.
1175
Thomas Heller47d7a062006-07-12 08:43:47 +00001176- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1177 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001178
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001179- Because of a misspelled preprocessor symbol, ctypes was always
1180 compiled without thread support; this is now fixed.
1181
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001182- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1183 methods now allow their database parameter to be None as the
1184 sleepycat API allows.
1185
Matt Flemingec926502006-07-28 11:27:27 +00001186- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1187 bluetooth API compared with Linux and FreeBSD.
1188
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001189Tests
1190-----
1191
1192- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1193 how long the test file should take to play. Now accepts taking 2.93 secs
1194 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1195
Georg Brandl4793aa32006-07-28 18:31:39 +00001196- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1197 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1198 run via ``regrtest.py``. Now they do.

Martin v. Löwis0907f4d2006-07-30 14:09:47 +00001200Build
1201-----
1202
1203- Bug #1439538: Drop usage of test -e in configure as it is not portable.
1204
Ronald Oussoren26cad082006-08-01 21:00:57 +00001205Mac
1206---
1207
1208- PythonLauncher now works correctly when the path to the script contains
1209 characters that are treated specially by the shell (such as quotes).
1210
1211- Bug #1527397: PythonLauncher now launches scripts with the working directory
1212 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001213 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001214 expect.

1222Core and builtins
1223-----------------
1224
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001225- Bug #1441486: The literal representation of -(sys.maxint - 1)
1226 again evaluates to a int object, not a long.
1227
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001228- Bug #1501934: The scope of global variables that are locally assigned
1229 using augmented assignment is now correctly determined.
1230
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001231- Bug #927248: Recursive method-wrapper objects can now safely
1232 be released.
1233
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001234- Bug #1417699: Reject locale-specific decimal point in float()
1235 and atof().
1236
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001237- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1238 omit a default "error" argument for NULL pointer. This allows
1239 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001240
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001241- Bug #1519018: 'as' is now validated properly in import statements.
1242
Neal Norwitz28746ab2006-07-09 22:14:42 +00001243- On 64 bit systems, int literals that use less than 64 bits are
1244 now ints rather than longs.
1245
Neal Norwitzed657552006-07-10 00:04:44 +00001246- Bug #1512814, Fix incorrect lineno's when code at module scope
1247 started after line 256.
1248
Tim Peters32a83612006-07-10 21:08:24 +00001249- New function ``sys._current_frames()`` returns a dict mapping thread
1250 id to topmost thread stack frame. This is for expert use, and is
1251 especially useful for debugging application deadlocks. The functionality
1252 was previously available in Fazal Majid's ``threadframe`` extension
1253 module, but it wasn't possible to do this in a wholly threadsafe way from
1254 an extension.
1255

1260 VS 2003.
1261
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001262- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1263
Tim Peters32a83612006-07-10 21:08:24 +00001264- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001265 environment variable to be set in order to the SDK environment
1266 for finding the compiler, include files, etc.

1271
Thomas Woutersadd19112006-07-05 11:03:49 +00001272- string.Template() now correctly handles tuple-values. Previously,
1273 multi-value tuples would raise an exception and single-value tuples would
1274 be treated as the value they contain, instead.
1275
Martin v. Löwisede77f52006-07-03 13:01:35 +00001276- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1277 even if some data are received.
1278
Martin v. Löwis45482392006-07-03 12:28:58 +00001279- Bug #1267547: Put proper recursive setup.py call into the
1280 spec file generated by bdist_rpm.
1281
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001282- Bug #1514693: Update turtle's heading when switching between
1283 degrees and radians.
1284
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001285- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001286 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001287
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001288- Bug #1514703: Only setup canvas window in turtle when the canvas
1289 is created.
1290
Martin v. Löwis7596e832006-07-01 15:33:37 +00001291- Bug #1513223: .close() of a _socketobj now releases the underlying
1292 socket again, which then gets closed as it becomes unreferenced.

1295 attribute values.
1296
1297- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1298 sgmllib ('[' and ']' were not accepted).
1299
Georg Brandl1be63af2006-06-28 20:23:25 +00001300- Fix a bug in the turtle module's end_fill function.
1301
Brett Cannon53ab5b72006-06-22 16:49:14 +00001302- Bug #1510580: The 'warnings' module improperly required that a Warning
1303 category be either a types.ClassType and a subclass of Warning. The proper
1304 check is just that it is a subclass with Warning as the documentation states.
1305
Georg Brandlad29e632006-06-21 17:45:17 +00001306- The compiler module now correctly compiles the new try-except-finally
1307 statement (bug #1509132).
1308
Neal Norwitz60373cd2006-06-22 06:30:50 +00001309- The wsgiref package is now installed properly on Unix.
1310
Vinay Sajip28e57612006-07-01 10:45:20 +00001311- A bug was fixed in logging.config.fileConfig() which caused a crash on
1312 shutdown when fileConfig() was called multiple times.
1313
Gerhard Häring762fbd32006-07-02 17:48:30 +00001314- The sqlite3 module did cut off data from the SQLite database at the first
1315 null character before sending it to a custom converter. This has been fixed
1316 now.
1317
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001318Extension Modules
1319-----------------
1320
Tim Peters112aad32006-07-19 00:03:19 +00001321- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1322 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1323 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001324
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001325- Assigning None to pointer type fields in ctypes structures possible
1326 overwrote the wrong fields, this is fixed now.
1327
1328- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1329 on non-Windows platforms.
1330
1331- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1332 integer or long, without range checking.
1333
1334- Patch #1517790: It is now possible to use custom objects in the ctypes
1335 foreign function argtypes sequence as long as they provide a from_param
1336 method, no longer is it required that the object is a ctypes type.
1337
1338- The '_ctypes' extension module now works when Python is configured
1339 with the --without-threads option.
1340
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001341- Bug #1513646: os.access on Windows now correctly determines write
1342 access, again.
1343
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001344- Bug #1512695: cPickle.loads could crash if it was interrupted with
1345 a KeyboardInterrupt.
1346
Neal Norwitza12aa882006-07-06 06:45:08 +00001347- Bug #1296433: parsing XML with a non-default encoding and
1348 a CharacterDataHandler could crash the interpreter in pyexpat.
1349
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001350- Patch #1516912: improve Modules support for OpenVMS.

1353-----
1354
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001355- Automate Windows build process for the Win64 SSL module.
1356
Tim Peters32a83612006-07-10 21:08:24 +00001357- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001358 Previously, the slight difference could cause compilation errors of the
1359 'zlib' module on systems with more than one version of zlib.
1360
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001361- The MSI compileall step was fixed to also support a TARGETDIR
1362 with spaces in it.
1363
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001364- Bug #1517388: sqlite3.dll is now installed on Windows independent
1365 of Tcl/Tk.
1366
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001367- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001368 trying to be installed even though it's empty.
Georg Brandlad29e632006-06-21 17:45:17 +00001369
Neal Norwitzb15ac312006-06-29 04:10:08 +00001370Tests
1371-----
1372
1373- Call os.waitpid() at the end of tests that spawn child processes in order
1374 to minimize resources (zombies).
1375
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001376Documentation
1377-------------
1378
Nick Coghlan2d792252006-07-06 13:47:18 +00001379- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1380 documentation for the warnings module.
1381
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001382- Patch #1509163: MS Toolkit Compiler no longer available.
1383

Nick Coghlanc649ec52006-05-29 12:43:05 +00001387What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +00001388================================
Anthony Baxter51bcb682006-04-05 14:51:42 +00001389
Anthony Baxterd1136802006-06-19 12:04:15 +00001390*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +00001391
1392Core and builtins
1393-----------------
1394
Georg Brandla56b9152006-06-19 06:35:54 +00001395- Patch #1507676: Error messages returned by invalid abstract object operations
1396 (such as iterating over an integer) have been improved and now include the
1397 type of the offending object to help with debugging.
1398
Brett Cannonea3912b2006-06-13 21:46:41 +00001399- Bug #992017: A classic class that defined a __coerce__() method that returned
1400 its arguments swapped would infinitely recurse and segfault the interpreter.
1401
Neal Norwitz909eb122006-06-12 02:13:21 +00001402- Fix the socket tests so they can be run concurrently.
1403
Neal Norwitzb9845e72006-06-12 02:11:18 +00001404- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001405 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001406
Brett Cannon22565aa2006-06-09 22:31:23 +00001407- Bug #532646: object.__call__() will continue looking for the __call__
1408 attribute on objects until one without one is found. This leads to recursion
1409 when you take a class and set its __call__ attribute to an instance of the
1410 class. Originally fixed for classic classes, but this fix is for new-style.
1411 Removes the infinite_rec_3 crasher.
1412
Georg Brandl24250812006-06-09 18:45:48 +00001413- The string and unicode methods startswith() and endswith() now accept
1414 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1415
Brett Cannonde3b0522006-06-08 17:00:45 +00001416- Buffer objects, at the C level, never used the char buffer
1417 implementation even when the char buffer for the wrapped object was
1418 explicitly requested (originally returned the read or write buffer).
1419 Now a TypeError is raised if the char buffer is not present but is
1420 requested.
1421
Georg Brandlddbaa662006-06-04 21:56:52 +00001422- Patch #1346214: Statements like "if 0: suite" are now again optimized
1423 away like they were in Python 2.4.
1424
Georg Brandlb7c8f542006-05-27 12:30:25 +00001425- Builtin exceptions are now full-blown new-style classes instead of
1426 instances pretending to be classes, which speeds up exception handling
1427 by about 80% in comparison to 2.5a2.
1428
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001429- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1430 Unicode 4.1.
1431
Georg Brandlf4ef1162006-05-26 18:03:31 +00001432- Patch #921466: sys.path_importer_cache is now used to cache valid and
1433 invalid file paths for the built-in import machinery which leads to
1434 fewer open calls on startup.
1435
Tim Peters696cf432006-05-24 21:10:40 +00001436- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1437 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1438 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1439 the number of input digits (it was and remains linear-time for bases
1440 2, 4, 8, 16 and 32).
1441
Tim Petersb713ec22006-05-23 18:45:30 +00001442- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1443 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1444 an integer close to ``sys.maxint``. This was repaired by patch
1445 #1335972, which also gives a nice speedup.
1446
Richard Jonescebbefc2006-05-23 18:28:17 +00001447- Patch #1337051: reduced size of frame objects.
1448
1449- PyErr_NewException now accepts a tuple of base classes as its
1450 "base" parameter.
1451
Richard Jones7c88dcc2006-05-23 10:37:38 +00001452- Patch #876206: function call speedup by retaining allocated frame
1453 objects.
1454
Georg Brandl7b90e162006-05-18 07:01:27 +00001455- Bug #1462152: file() now checks more thoroughly for invalid mode
1456 strings and removes a possible "U" before passing the mode to the
1457 C library function.
1458
Neal Norwitz1004a532006-05-15 07:17:23 +00001459- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1460
Neal Norwitz373f0a72006-05-15 07:04:36 +00001461- Bug #1487966: Fix SystemError with conditional expression in assignment
1462
Martin v. Löwis879768d2006-05-11 13:28:43 +00001463- WindowsError now has two error code attributes: errno, which carries
1464 the error values from errno.h, and winerror, which carries the error
1465 values from winerror.h. Previous versions put the winerror.h values
1466 (from GetLastError()) into the errno attribute.
1467
Martin v. Löwis77736712006-05-04 05:51:03 +00001468- Patch #1475845: Raise IndentationError for unexpected indent.
1469
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001470- Patch #1479181: split open() and file() from being aliases for each other.
1471
Tim Peters44bd9862006-06-01 13:49:23 +00001472- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1473 methods were always silently ignored by dictionaries when comparing keys.
1474 They are now passed through (except when using the C API function
1475 ``PyDict_GetItem()``, whose semantics did not change).
1476
1477- Bug #1456209: In some obscure cases it was possible for a class with a
1478 custom ``__eq__()`` method to confuse dict internals when class instances
1479 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1480 No, you don't have any code that did this ;-)

1483-----------------
1484
Trent Mick960a3f82006-06-28 20:30:41 +00001485- Bug #1295808: expat symbols should be namespaced in pyexpat
1486
1487- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1488
Brett Cannon6ee7d012006-06-08 16:23:04 +00001489- Change binascii.hexlify to accept a read-only buffer instead of only a char
1490 buffer and actually follow its documentation.
1491
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001492- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1493
Nick Coghlanc649ec52006-05-29 12:43:05 +00001494- Patch #1478788 (modified version): The functional extension module has
1495 been renamed to _functools and a functools Python wrapper module added.
1496 This provides a home for additional function related utilities that are
1497 not specifically about functional programming. See PEP 309.
1498
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001499- Patch #1493701: performance enhancements for struct module.
1500
Georg Brandl378d5922006-05-17 14:26:50 +00001501- Patch #1490224: time.altzone is now set correctly on Cygwin.
1502
Georg Brandl8d3342b2006-05-16 07:38:27 +00001503- Patch #1435422: zlib's compress and decompress objects now have a
1504 copy() method.
1505
Andrew MacIntyre92913322006-06-13 15:04:24 +00001506- Patch #1454481: thread stack size is now tunable at runtime for thread
1507 enabled builds on Windows and systems with Posix threads support.
1508
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001509- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1510 (up to the system limit of 32K characters).
1511
1512- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1513 As a result, these functions now raise WindowsError instead of OSError.
1514
Tim Peters7a822da2006-05-25 21:50:17 +00001515- ``time.clock()`` on Win64 should use the high-performance Windows
1516 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1517 Windows platforms).
1518
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001519- Calling Tk_Init twice is refused if the first call failed as that
1520 may deadlock.
1521
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001522- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1523 accept it without potentially using an uninitialized pointer.
1524
1525- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1526 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1527 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001528
Gregory P. Smith372b5832006-06-05 18:48:21 +00001529- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001530 [pybsddb project SF patch number 1466734]
1531
Gregory P. Smith372b5832006-06-05 18:48:21 +00001532- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1533 parameter is supplied. [SF pybsddb bug #1477863]
1534
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001535- bsddb: the __len__ method of a DB object has been fixed to return correct
1536 results. It could previously incorrectly return 0 in some cases.
1537 Fixes SF bug 1493322 (pybsddb bug 1184012).
1538
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001539- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1540 aborts the db transaction safely when a modifier callback fails.
1541 Fixes SF python patch/bug #1408584.
1542
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001543- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001544 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001545 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1546 database calls that would previously deadlock. [SF python bug #775414]
1547
Vinay Sajip28e57612006-07-01 10:45:20 +00001548- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001549
Walter Dörwald4994d952006-06-19 08:07:50 +00001550- Patch #1506645: add Python wrappers for the curses functions
1551 is_term_resized, resize_term and resizeterm.

1557 functions.
1558
Martin v. Löwis3798da02006-06-17 18:44:27 +00001559- Patch #812986: Update turtle output even if not tracing.

Vinay Sajip28e57612006-07-01 10:45:20 +00001561- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001562 Tkinter.BaseWidget.
1563
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001564- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.

1567 classes.
1568
Georg Brandl83cc0d02006-06-14 08:50:03 +00001569- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1570 mime.types file for determining MIME types.
1571
Georg Brandl2605ca82006-06-14 06:08:31 +00001572- Bug #1339007: Shelf objects now don't raise an exception in their
1573 __del__ method when initialization failed.
1574
Martin v. Löwisd8251432006-06-14 05:21:04 +00001575- Patch #1455898: The MBCS codec now supports the incremental mode for
1576 double-byte encodings.
1577
Tim Peters43898b42006-06-14 04:09:25 +00001578- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1579 guarantee that adjacent triples in the return list always describe
1580 non-adjacent blocks. Previously, a pair of matching blocks could end
1581 up being described by multiple adjacent triples that formed a partition
1582 of the matching pair.
1583
Greg Ward0e0c9f42006-06-11 16:24:11 +00001584- Bug #1498146: fix optparse to handle Unicode strings in option help,
1585 description, and epilog.
1586
Greg Wardd1c797e2006-06-11 14:42:41 +00001587- Bug #1366250: minor optparse documentation error.
1588
Greg Ward7f547402006-06-11 00:40:49 +00001589- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1590 clarify docs.
1591
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001592- The wsgiref package has been added to the standard library.
1593
Nick Coghlan676725d2006-06-08 13:54:49 +00001594- The functions update_wrapper() and wraps() have been added to the functools
1595 module. These make it easier to copy relevant metadata from the original
1596 function when writing wrapper functions.
1597
Tim Petersd6a9eef2006-06-05 01:48:21 +00001598- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1599 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001600
Martin v. Löwis3f767792006-06-04 19:36:28 +00001601- Patch #1359618: Speed up charmap encoder by using a trie structure
1602 for lookup.
1603
Tim Petersd609b1a2006-06-02 23:22:51 +00001604- The functions in the ``pprint`` module now sort dictionaries by key
1605 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1606 if and only if its display required more than one line, although that
1607 wasn't documented. The new behavior increases predictability; e.g.,
1608 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1609
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001610- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1611 (thanks for J. J. Lee).
1612
Georg Brandl2b330372006-05-28 20:23:12 +00001613- Patch #1496206: improve urllib2 handling of passwords with respect to
1614 default HTTP and HTTPS ports.
1615
George Yoshidaf3c65de2006-05-28 16:39:09 +00001616- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1617
Bob Ippolito7298f272006-05-23 18:43:47 +00001618- Patch #1281707: speed up gzip.readline.
1619
Georg Brandlb89316f2006-05-17 15:51:16 +00001620- Patch #1180296: Two new functions were added to the locale module:
1621 format_string() to get the effect of "format % items" but locale-aware,
1622 and currency() to format a monetary number with currency sign.
1623
Georg Brandle3a25832006-05-17 14:56:04 +00001624- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1625 and several features added, such as speed and geometry control.
1626
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001627- Patch #1488881: add support for external file objects in bz2 compressed
1628 tarfiles.
1629
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001630- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1631 stdout arguments, making it possible to redirect input and output
1632 for remote debugging.
1633
1634- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1635 a couple of issues, notably handling of long file names using the
1636 GNU LONGNAME extension.
1637
1638- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1639 new flag when ``name`` is already the name of an option flag.
1640
1641- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1642 package.
1643
1644- Patch #1472854: make the rlcompleter.Completer class usable on non-
1645 UNIX platforms.
1646
1647- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1648
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001649- Bug #1472827: correctly escape newlines and tabs in attribute values in

1685Core and builtins
1686-----------------
1687
Thomas Heller1b046642006-04-18 18:51:06 +00001688- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1689 by converting these apis from macros into exported functions again:
1690
1691 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1692 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1693 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1694 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1695 PyRun_String Py_CompileString
1696
Martin v. Löwis45294a92006-04-18 06:24:08 +00001697- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1698
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001699- All uses of PyStructSequence_InitType have been changed to initialize
1700 the type objects only once, even if the interpreter is initialized
1701 multiple times.
1702
Neal Norwitz61546162006-04-14 05:20:28 +00001703- Bug #1454485, array.array('u') could crash the interpreter. This was
1704 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1705 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1706
1707- Py_UNICODE is unsigned. It was always documented as unsigned, but
1708 due to a bug had a signed value in previous versions.
1709
Tim Peters3a5e8b12006-04-11 01:44:07 +00001710- Patch #837242: ``id()`` of any Python object always gives a positive
1711 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1712 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001713 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001714 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001715
Tim Peters3a5e8b12006-04-11 01:44:07 +00001716 def __hash__(self):
1717 return id(self) # WRONG
1718
1719 because a hash result must be a (short) Python int but it was always
1720 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001721 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001722 was always usable as a hash value before this patch. That's no longer
1723 necessarily so.
1724
1725- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001726 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001727 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001728 #1454844)
1729
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001730- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1731 involving generators that have paused outside of any ``try`` or ``with``
1732 blocks. (In 2.5a1, a paused generator that was part of a reference
1733 cycle could not be garbage collected, regardless of whether it was
1734 paused in a ``try`` or ``with`` block.)

1741
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001742- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1743 fails with an error condition.
1744
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001745- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1746
1747- Bug #1117761: bsddb.*open() no longer raises an exception when using
1748 the cachesize parameter.
1749
1750- Bug #1149413: bsddb.*open() no longer raises an exception when using
1751 a temporary db (file=None) with the 'n' flag to truncate on open.
1752
1753- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1754 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001755
Armin Rigoa9017c32006-04-19 11:50:27 +00001756- Patch #1062014: AF_UNIX sockets under Linux have a special
1757 abstract namespace that is now fully supported.

1760-------
1761
Peter Astrand7d1d4362006-07-14 14:04:45 +00001762- Bug #1223937: subprocess.CalledProcessError reports the exit status
1763 of the process using the returncode attribute, instead of
1764 abusing errno.
1765
Tim Peters711bf302006-04-25 03:31:36 +00001766- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1767 a doctest to be skipped (the code is not run, and the expected output
1768 or exception is ignored).
1769
Nick Coghlanda2268f2006-04-24 04:37:15 +00001770- Fixed contextlib.nested to cope with exceptions being raised and
1771 caught inside exit handlers.
1772
Greg Wardab05edc2006-04-23 03:47:58 +00001773- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1774 hex, octal, or binary; add ``append_const`` action; keep going if
1775 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1776 added ``epilog`` for better help generation).
1777
Tim Peters21fbd572006-04-21 21:18:10 +00001778- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1779 called from a thread spawned as a side effect of importing a module.
1780
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001781- The pydoc module now supports documenting packages contained in
1782 .zip or .egg files.
1783
1784- The pkgutil module now has several new utility functions, such
1785 as ``walk_packages()`` to support working with packages that are either
1786 in the filesystem or zip files.
1787
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001788- The mailbox module can now modify and delete messages from
1789 mailboxes, in addition to simply reading them. Thanks to Gregory
1790 K. Johnson for writing the code, and to the 2005 Google Summer of
1791 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001792
Tim Petersc7605f22006-04-17 21:12:33 +00001793- The ``__del__`` method of class ``local`` in module ``_threading_local``
1794 returned before accomplishing any of its intended cleanup.

1804
Phillip J. Eby47032112006-04-11 01:07:43 +00001805- The warnings, linecache, inspect, traceback, site, and doctest modules
1806 were updated to work correctly with modules imported from zipfiles or
1807 via other PEP 302 __loader__ objects.
1808
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001809- Patch #1467770: Reduce usage of subprocess._active to processes which
1810 the application hasn't waited on.

1815
Skip Montanaro262fb922006-04-21 02:31:07 +00001816- The pstats.Stats class accepts an optional stream keyword argument to
1817 direct output to an alternate file-like object.
1818
Anthony Baxter51bcb682006-04-05 14:51:42 +00001819Build
1820-----
1821
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001822- The Makefile now has a reindent target, which runs reindent.py on
1823 the library.
1824
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001825- Patch #1470875: Building Python with MS Free Compiler
1826
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001827- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001828
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001829- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1830 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001831 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001832 CXX from --with-cxx-main, see description in README.
1833
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001834- Patch #1429775: Link extension modules with the shared libpython.
1835
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001836- Fixed a libffi build problem on MIPS systems.
1837
Tim Peters8931ff12006-05-13 23:28:20 +00001838- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1839 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1840 and "%zu" for unsigned integers of type ``size_t``.
1841
Anthony Baxter51bcb682006-04-05 14:51:42 +00001842Tests
1843-----
1844
Nick Coghlanda2268f2006-04-24 04:37:15 +00001845- test_contextlib now checks contextlib.nested can cope with exceptions
1846 being raised and caught inside exit handlers.
1847
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001848- test_cmd_line now checks operation of the -m and -c command switches
1849
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001850- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1851 it separately and by hand. It also wasn't cleaning up its changes to
1852 the current Decimal context.
1853
Thomas Woutersabd08882006-04-26 15:53:30 +00001854- regrtest.py now has a -M option to run tests that test the new limits of
1855 containers, on 64-bit architectures. Running these tests is only sensible
1856 on 64-bit machines with more than two gigabytes of memory. The argument
1857 passed is the maximum amount of memory for the tests to use.

1866-------------
1867
Tim Petersb06d28c2006-05-12 01:57:59 +00001868- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1869
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001870- PEP 343: Added Context Types section to the library reference
1871 and attempted to bring other PEP 343 related documentation into
1872 line with the implementation and/or python-dev discussions.
1873
Tim Peters8dc73d22006-04-24 02:03:16 +00001874- Bug #1337990: clarified that ``doctest`` does not support examples
1875 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001878What's New in Python 2.5 alpha 1?
1879=================================
1880
Anthony Baxterebed3f62006-04-03 15:03:44 +00001881*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001882
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001883Core and builtins
1884-----------------
1885
Nick Coghlan43832302006-04-23 17:04:07 +00001886- PEP 338: -m command line switch now delegates to runpy.run_module
1887 allowing it to support modules in packages and zipfiles
1888
Martin v. Löwisc661b882006-04-20 04:54:23 +00001889- On Windows, .DLL is not an accepted file name extension for
1890 extension modules anymore; extensions are only found if they
1891 end in .PYD.
1892
Martin v. Löwisea62d252006-04-03 10:56:49 +00001893- Bug #1421664: sys.stderr.encoding is now set to the same value as
1894 sys.stdout.encoding.
1895
Neal Norwitz92e212f2006-04-03 04:48:37 +00001896- __import__ accepts keyword arguments.
1897
Georg Brandlccadf842006-03-31 18:54:53 +00001898- Patch #1460496: round() now accepts keyword arguments.
1899
Anthony Baxter262c00a2006-03-30 10:53:17 +00001900- Fixed bug #1459029 - unicode reprs were double-escaped.
1901
Hye-Shik Changd478f342006-03-23 12:32:36 +00001902- Patch #1396919: The system scope threads are reenabled on FreeBSD
1903 5.4 and later versions.
1904
Neal Norwitze98ccf62006-03-23 05:39:47 +00001905- Bug #1115379: Compiling a Unicode string with an encoding declaration
1906 now gives a SyntaxError.
1907
Georg Brandlabd1ff82006-03-18 07:59:59 +00001908- Previously, Python code had no easy way to access the contents of a
1909 cell object. Now, a ``cell_contents`` attribute has been added
1910 (closes patch #1170323).
1911
Tim Peterscf79aac2006-03-16 01:14:46 +00001912- Patch #1123430: Python's small-object allocator now returns an arena to
1913 the system ``free()`` when all memory within an arena becomes unused
1914 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1915 freed. Some applications will see a drop in virtual memory size now,
1916 especially long-running applications that, from time to time, temporarily
1917 use a large number of small objects. Note that when Python returns an
1918 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001919 platform C library will in turn return that memory to the operating system.
1920 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001921 appears to be effective at least on Microsoft C and gcc-based systems.
1922 Thanks to Evan Jones for hard work and patience.
1923
Georg Brandl533ff6f2006-03-08 18:09:27 +00001924- Patch #1434038: property() now uses the getter's docstring if there is
1925 no "doc" argument given. This makes it possible to legitimately use
1926 property() as a decorator to produce a read-only property.
1927
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001928- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1929 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1930 of requiring an int or long in slicing and a few other contexts, enabling
1931 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1932
Neal Norwitz995acdf2006-03-07 05:01:00 +00001933- Fixed various bugs reported by Coverity's Prevent tool.
1934
Brett Cannonbf364092006-03-01 04:25:17 +00001935- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1936 new exception base class, BaseException, which has a new message attribute.
1937 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1938 Raising a string exception now raises a DeprecationWarning.
1939
Thomas Woutersfb609f42006-02-28 16:37:25 +00001940- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1941 explicitly relative, using 'from .module import name' to mean 'from the same
1942 package as this module is in. Imports without dots still default to the
1943 old relative-then-absolute, unless 'from __future__ import
1944 absolute_import' is used.
1945
Brett Cannona7446e32006-02-27 23:39:10 +00001946- Properly check if 'warnings' raises an exception (usually when a filter set
1947 to "error" is triggered) when raising a warning for raising string
1948 exceptions.
1949
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001950- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001951 The name was removed from Include/code.h.
1952
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001953- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001954
Guido van Rossum1968ad32006-02-25 22:38:04 +00001955- Patch 1433928:
1956 - The copy module now "copies" function objects (as atomic objects).
1957 - dict.__getitem__ now looks for a __missing__ hook before raising
1958 KeyError.
1959
Tim Peters84ef21c2006-02-28 20:39:06 +00001960- PEP 343: with statement implemented. Needs ``from __future__ import
1961 with_statement``. Use of 'with' as a variable will generate a warning.
1962 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001963 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001964 The following objects have __context__ methods:
1965 - The built-in file type.
1966 - The thread.LockType type.
1967 - The following types defined by the threading module:
1968 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1969 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001970
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001971- Fix the encodings package codec search function to only search
1972 inside its own package. Fixes problem reported in patch #1433198.
1973
1974 Note: Codec packages should implement and register their own
1975 codec search function. PEP 100 has the details.
1976
Tim Peters9ea89d22006-06-04 03:26:02 +00001977- PEP 353: Using ``Py_ssize_t`` as the index type.
1978
1979- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1980 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1981 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1982 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1983 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001984
Neal Norwitzfc76d632006-01-10 06:03:13 +00001985- Patch #1400181, fix unicode string formatting to not use the locale.
1986 This is how string objects work. u'%f' could use , instead of .
1987 for the decimal point. Now both strings and unicode always use periods.
1988
Neal Norwitz671b9e32006-01-09 07:07:12 +00001989- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1990 configure would break checking curses.h.
1991
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001992- Bug #959576: The pwd module is now builtin. This allows Python to be
1993 built on UNIX platforms without $HOME set.
1994
Neal Norwitzc10978f2005-12-19 06:07:16 +00001995- Bug #1072182, fix some potential problems if characters are signed.
1996
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001997- Bug #889500, fix line number on SyntaxWarning for global declarations.
1998
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001999- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2000
Neal Norwitze7214a12005-12-18 05:03:17 +00002001- Support for converting hex strings to floats no longer works.
2002 This was not portable. float('0x3') now raises a ValueError.
2003
Barry Warsaw2a38a862005-12-18 01:27:35 +00002004- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002005 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002006 is now displayed in interactive prompt banner.
2007
Georg Brandlfa166682005-12-17 21:45:17 +00002008- Implementation of PEP 341 - Unification of try/except and try/finally.
2009 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002010 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002011
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002012- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2013 now encodes backslash correctly.
2014
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002015- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2016
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002017- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002018 and long longs.
2019
Neal Norwitz67715f02005-11-09 06:59:35 +00002020- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002021 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002022 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002023
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002024- Replaced most Unicode charmap codecs with new ones using the
2025 new Unicode translate string feature in the builtin charmap
2026 codec; the codecs were created from the mapping tables available
2027 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2028 encodings now include a mapping for the Apple logo)
2029
Tim Peterse3547fd2005-12-16 23:13:57 +00002030- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002031
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002032- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002033
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002034- A new AST parser implementation was completed. The abstract
2035 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002036 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002037
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002038- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002039 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2040
Neal Norwitz708e51a2005-10-03 04:48:15 +00002041- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2042
Neal Norwitz11bd1192005-10-03 00:54:56 +00002043- SF Bug #887946: fix segfault when redirecting stdin from a directory.

2049
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002050- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002051 supported a __len__() method which evaluated to False when the iterator
2052 was empty.
2053
Guido van Rossum630db602005-09-20 18:49:54 +00002054- On 64-bit platforms, when __len__() returns a value that cannot be
2055 represented as a C int, raise OverflowError.
2056
Skip Montanarof8948ca2005-09-19 03:54:46 +00002057- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002058 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002059
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002060- SF bug #893549: parsing keyword arguments was broken with a few format
2061 codes.
2062
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002063- Changes donated by Elemental Security to make it work on AIX 5.3
2064 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2065 bug #105470: test_pwd fails on 64bit system (Opteron).
2066
Guido van Rossum539c6622005-09-14 17:49:54 +00002067- Changes donated by Elemental Security to make it work on HP-UX 11 on
2068 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2069
Georg Brandl4550b8d2005-08-26 06:43:52 +00002070- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002071 (fixes bug #1119418).
2072
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002073- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2074
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002075- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2076 exceptions that cause a function to exit.
2077
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002078- The implementation of set() and frozenset() was revised to use its
2079 own internal data structure. Memory consumption is reduced by 1/3
2080 and there are modest speed-ups as well. The API is unchanged.
2081
Tim Petersde7990b2005-07-17 23:45:23 +00002082- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2083
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002084- SF bug #1229429: PyObject_CallMethod failed to decrement some
2085 reference counts in some error exit cases.
2086
Tim Petersecc6e6a2005-07-10 22:30:55 +00002087- SF bug #1185883: Python's small-object memory allocator took over
2088 a block managed by the platform C library whenever a realloc specified
2089 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002090 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002091 portable way to copy data from the C-managed block into Python's
2092 small-object space without risking a memory fault. Python's small-object
2093 realloc now leaves such blocks under the control of the platform C
2094 realloc.
2095
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002096- SF bug #1232517: An overflow error was not detected properly when
2097 attempting to convert a large float to an int in os.utime().
2098
Raymond Hettinger3296e692005-06-29 23:29:56 +00002099- SF bug #1224347: hex longs now print with lowercase letters just
2100 like their int counterparts.
2101
Michael W. Hudson188d4362005-06-20 16:52:57 +00002102- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2103 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2104 interpreter states; back out that fix and do a better job (see
2105 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2106 for a longer write-up of the problem).
2107
Michael W. Hudsondf888462005-06-03 14:41:55 +00002108- SF patch #1180995: marshal now uses a binary format by default when
2109 serializing floats.
2110
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002111- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2112 the routines that promise to produce IEEE 754 binary representations
2113 of floats now simply copy bytes around.
2114
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002115- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2116 278.
2117
Brett Cannonc3647ac2005-04-26 03:45:26 +00002118- patch #1109424: int, long, float, complex, and unicode now check for the
2119 proper magic slot for type conversions when subclassed. Previously the
2120 magic slot was ignored during conversion. Semantics now match the way
2121 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002122 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002123 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002124 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002125
Barry Warsawc8d907c2005-04-19 23:43:40 +00002126- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2127 NULL, now raise an AttributeError when attempting to set or delete the
2128 attribute. Previously a TypeError was raised, but this was inconsistent
2129 with the equivalent pure-Python implementation.
2130
Michael W. Hudson774479c2005-04-18 08:46:17 +00002131- It is now safe to call PyGILState_Release() before
2132 PyEval_InitThreads() (note that if there is reason to believe there
2133 are multiple threads around you still must call PyEval_InitThreads()
2134 before using the Python API; this fix is for extension modules that
2135 have no way of knowing if Python is multi-threaded yet).
2136
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002137- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2138 disabled caused a crash.
2139
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002140- Bug #1165306: instancemethod_new allowed the creation of a method
2141 with im_class == im_self == NULL, which caused a crash when called.
2142
Tim Petersecc6e6a2005-07-10 22:30:55 +00002143- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002144 fixes the crash seen in bug #1165761
2145
Raymond Hettinger96229b12005-03-11 06:49:40 +00002146- Added two new builtins, any() and all().
2147
Brett Cannon409d8f22005-03-05 06:47:57 +00002148- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002149 (e.g., ``class C(): pass`` is no longer a syntax error).
2150 Patch #1176012 added support to the 'parser' module and 'compiler' package
2151 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002152
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002153- Patch #1115086: Support PY_LONGLONG in structmember.
2154
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002155- Bug #1155938: new style classes did not check that __init__() was
2156 returning None.
2157
Tim Petersecc6e6a2005-07-10 22:30:55 +00002158- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002159 ('\') with a specific error message.
2160
Martin v. Löwisff232d72005-03-03 09:24:38 +00002161- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2162
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002163- Bug #1124295: the __name__ attribute of file objects was
2164 inadvertently made inaccessible in restricted mode.
2165
Tim Petersecc6e6a2005-07-10 22:30:55 +00002166- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002167 an ferror() call.
2168
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002169- min() and max() now support key= arguments with the same meaning as in
2170 list.sort().
2171
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002172- The peephole optimizer now performs simple constant folding in expressions:
2173 (2+3) --> (5).
2174
Raymond Hettingera422c342005-01-11 03:03:27 +00002175- set and frozenset objects can now be marshalled. SF #1098985.
2176
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002177- Bug #1077106: Poor argument checking could cause memory corruption
2178 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002179
Jeremy Hyltonab630502005-02-04 18:44:06 +00002180- The parser did not complain about future statements in illegal
2181 positions. It once again reports a syntax error if a future
2182 statement occurs after anything other than a doc string.
2183
Neil Schemenauercf52c072005-08-12 17:34:58 +00002184- Change the %s format specifier for str objects so that it returns a
2185 unicode instance if the argument is not an instance of basestring and
2186 calling __str__ on the argument returns a unicode instance.
2187
Tim Petersf4e69282006-02-27 17:15:31 +00002188- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2189 current thread state when the auto-GIL-state machinery knows about
2190 it (since the thread state is being deleted, continuing to remember it
2191 can't help, but can hurt if another thread happens to get created with
2192 the same thread id).
2193
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002194Extension Modules
2195-----------------
2196

Tim Petersc9d78aa2006-03-26 23:27:58 +00002209 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00002210 util, whatsound, whrandom, zmod
2211
2212- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2213
2214- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002215 is deprecated. The undocumented re.engine variable no longer exists.
2216
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002217- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2218 SS2 (single-shift 2) escape sequences correctly.
2219
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002220- The unicodedata module was updated to the 4.1 version of the Unicode
2221 database. The 3.2 version is still available as unicodedata.db_3_2_0
2222 for applications that require this specific version (such as IDNA).
2223
Neal Norwitzb62c4332006-03-04 18:35:47 +00002224- The timing module is no longer built by default. It was deprecated
2225 in PEP 4 in Python 2.0 or earlier.
2226
Guido van Rossum1968ad32006-02-25 22:38:04 +00002227- Patch 1433928: Added a new type, defaultdict, to the collections module.
2228 This uses the new __missing__ hook behavior added to dict (see above).
2229
Georg Brandldbd83392006-02-20 09:42:33 +00002230- Bug #854823: socketmodule now builds on Sun platforms even when
2231 INET_ADDRSTRLEN is not defined.
2232
Georg Brandlf4f44152006-02-18 22:29:33 +00002233- Patch #1393157: os.startfile() now has an optional argument to specify
2234 a "command verb" to invoke on the file.
2235
Neal Norwitz082b2df2006-02-07 07:04:46 +00002236- Bug #876637, prevent stack corruption when socket descriptor

2238
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00002239- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
2240 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
2241 mmap.mmap(0, size) should not be used on Windows for anonymous memory.

2244 than the system default domain.
2245
Martin v. Löwis14694662006-02-03 12:54:16 +00002246- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2247 are reported, the limit on path name lengths is removed, and stat reports
2248 WindowsError now (instead of OSError).
2249
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002250- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

2325 the request code argument, which results in more C-like behaviour
2326 for large or negative values.
2327
Tim Petersecc6e6a2005-07-10 22:30:55 +00002328- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

2340 were set in a different thread than that which called readline.
2341
Raymond Hettinger4aec61e2005-03-18 21:20:23 +00002342- collections.deque objects now support a remove() method.
2343
Raymond Hettinger984f9bb2005-03-09 16:38:48 +00002344- operator.itemgetter() and operator.attrgetter() now support retrieving

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002384- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2385 been renamed to have only a single underscore prefix. This was done to
2386 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002387
Nick Coghlan43832302006-04-23 17:04:07 +00002388- PEP 338: new module runpy defines a run_module function to support
2389 executing modules which provide access to source code or a code object
2390 via the PEP 302 import mechanisms.
2391
Anthony Baxter93f5b932006-04-03 08:05:07 +00002392- The email module's parsedate_tz function now sets the daylight savings

2400 in attribute values.
2401
Anthony Baxterc51ee692006-04-01 00:57:31 +00002402- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002403 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002404 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002405 module will not be built.
2406
Tim Petersc17976e2006-04-01 00:26:53 +00002407- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2408 aren't officially supported here, and trying to use them will probably
2409 raise an exception some day. But dicts have been allowed, and "mostly
2410 worked", so support for them won't go away without warning.
2411
Georg Brandl338ef7d2006-03-31 18:42:16 +00002412- Bug #1445068: getpass.getpass() can now be given an explicit stream
2413 argument to specify where to write the prompt.
2414

2424 to make it easier to monitor when daemon threads have completed
2425 processing all enqueued tasks. Patch #1455676.
2426

2430
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002431- email 4.0 package now integrated. This is largely the same as the email 3.0
2432 package that was included in Python 2.3, except that PEP 8 module names are
2433 now used (e.g. mail.message instead of email.Message). The MIME classes
2434 have been moved to a subpackage (e.g. email.mime.text instead of
2435 email.MIMEText). The old names are still supported for now. Several
2436 deprecated Message methods have been removed and lots of bugs have been
2437 fixed. More details can be found in the email package documentation.
2438
Walter Dörwald40108c92006-03-27 08:15:44 +00002439- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2440 (a subclass of tuple) that provides incremental decoders and encoders
2441 (a way to use stateful codecs without the stream API). Python functions
2442 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2443 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2444 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002445
Walter Dörwald067db482006-03-15 22:17:27 +00002446- Patch #1359365: Calling next() on a closed StringIO.String object raises
2447 a ValueError instead of a StopIteration now (like file and cString.String do).
2448 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2449 called before (like file and StringIO.StringIO do).

Tim Peterse3547fd2005-12-16 23:13:57 +00002523 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2524 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2525 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2526 Ronald L. Rivest offered this advice for Python:
2527
2528 "The consensus of researchers in this area (at least as
2529 expressed at the NIST Hash Function Workshop 10/31/05),
2530 is that SHA-256 is a good choice for the time being, but
2531 that research should continue, and other alternatives may
2532 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002533
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002534- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandlb9256022005-08-24 18:46:39 +00002580- Patch #1062060: urllib.urlretrieve() now raises a new exception, named
2581 ContentTooShortException, when the actually downloaded size does not
2582 match the Content-Length header.
2583
Martin v. Löwis0a5d4a22005-08-24 14:55:22 +00002584- Bug #1121494: distutils.dir_utils.mkpath now accepts Unicode strings.
2585
Martin v. Löwis56066d22005-08-24 07:38:12 +00002586- Bug #1178484: Return complete lines from codec stream readers
2587 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002588 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002589
Georg Brandl6d2b3462005-08-24 07:36:17 +00002590- Bug #1192315: Disallow negative arguments to clear() in pdb.

2595 to ntpath, macpath, os2emxpath and riscospath.
2596
Guido van Rossum755149f2005-07-27 00:00:44 +00002597- Fix a problem in Tkinter introduced by SF patch #869468: delete bogus
2598 __hasattr__ and __delattr__ methods on class Tk that were breaking
2599 Tkdnd.
2600
Georg Brandl5dbda752005-07-17 20:27:41 +00002601- Bug #1015140: disambiguated the term "article id" in nntplib docs and
2602 docstrings to either "article number" or "message id".
2603
Georg Brandla4a8b822005-07-15 09:13:21 +00002604- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
2605 parameter, but uses the usual "kwargs=None".
2606
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002607- textwrap now processes text chunks at O(n) speed instead of O(n**2).
Raymond Hettinger8bfa8932005-07-15 06:53:35 +00002608 Patch #1209527 (Contributed by Connelly).
2609
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00002610- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
2611 to W3C name (404 -> 'Not Found'). RFE #1216944.
2612
Georg Brandl9e43acf2005-07-04 17:16:07 +00002613- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2614 as this can cause problems with apps closing all file descriptors.
2615
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002616- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002617 it can be missing in embedded interpreters
Georg Brandl5284b532005-06-26 22:54:58 +00002618
Georg Brandl2f210b62005-06-26 22:09:06 +00002619- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
2620
Georg Brandlfbff1bc2005-06-26 21:36:25 +00002621- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
2622 error messages.
2623
Georg Brandl379f99d2005-06-26 21:09:38 +00002624- Bug #1108948: Cookie.py produced invalid JavaScript code.
2625
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00002626- The tokenize module now detects and reports indentation errors.
2627 Bug #1224621.
2628
Raymond Hettinger68c04532005-06-10 11:05:19 +00002629- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002630 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002631 the generate_tokens() function now accepts a callable argument that
2632 terminates by raising StopIteration.
2633
Georg Brandl9166e1a2005-06-04 09:20:03 +00002634- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2635
Georg Brandl268e61c2005-06-03 14:28:50 +00002636- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2637 component of the path.
2638
Skip Montanaro174dd222005-05-14 20:54:16 +00002639- Patch #1120353: The xmlrpclib module provides better, more transparent,
2640 support for datetime.{datetime,date,time} objects. With use_datetime set
2641 to True, applications shouldn't have to fiddle with the DateTime wrapper
2642 class at all.
2643
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002644- distutils.commands.upload was added to support uploading distribution
2645 files to PyPI.
2646
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002647- distutils.commands.register now encodes the data as UTF-8 before posting
2648 them to PyPI.
2649
Raymond Hettinger267b8682005-03-27 10:47:39 +00002650- decimal operator and comparison methods now return NotImplemented
2651 instead of raising a TypeError when interacting with other types. This
2652 allows other classes to implement __radd__ style methods and have them
2653 work as expected.
2654
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002655- Bug #1163325: Decimal infinities failed to hash. Attempting to
2656 hash a NaN raised an InvalidOperation instead of a TypeError.
2657
Tim Petersecc6e6a2005-07-10 22:30:55 +00002658- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002659 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2660
Martin v. Löwis00a73e72005-03-04 19:40:34 +00002661- Patch #1043890: Add extractall method to tarfile.

2664 to build.
2665
Martin v. Löwis637431b2005-03-03 23:12:42 +00002666- Patch #1103407: Properly deal with tarfile iterators when untarring

Martin v. Löwisa4dac402005-03-03 11:39:45 +00002670 profile.py if available.
2671
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00002672- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
2673

2675 in LWPCookieJar.
2676
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00002677- Patch #1117339: Add cookielib special name tests.
2678
Martin v. Löwise869eb12005-03-03 09:46:07 +00002679- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
2680

2682
Martin v. Löwisdf241532005-03-03 08:17:42 +00002683- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
2684
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00002685- Patch #1104111: Alter setup.py --help and --help-commands.
2686

2688
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00002689- Patch #1049151: xdrlib now unpacks booleans as True or False.
2690
Raymond Hettingerbab41432005-02-05 01:31:19 +00002691- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2692
Guido van Rossumd0641422005-02-03 15:01:24 +00002693- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2694 disables recursive traversal through instance attributes, which can
2695 be exploited in various ways.
2696
Tim Peterse3547fd2005-12-16 23:13:57 +00002697- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002698 flags on the HTTP listening socket.
2699
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002700- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2701 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2702
Fred Drakefbdeaad2006-07-29 16:56:15 +00002703- Patches #893642, #1039083: add allow_none, encoding arguments to
2704 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002705
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002706- Bug #1110478: Revert os.environ.update to do putenv again.
2707
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002708- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2709
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002710- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2711
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002712- Enhancements to the csv module:
2713
2714 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002715 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002716 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002717 + Dialect parameter parsing has been re-implemented to improve error
2718 reporting.
2719 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2720 dictates.
2721 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002722 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002723 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002724 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2725 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002726 + reader now allows \r characters to be quoted (previously it only allowed
2727 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002728 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002729 + Dialect classes passed to the module are no longer instantiated by
2730 the module before being parsed (the former validation scheme required
2731 this, but the mechanism was unreliable).
2732 + The dialect registry now contains instances of the internal
2733 C-coded dialect type, rather than references to python objects.
2734 + the internal c-coded dialect type is now immutable.
2735 + register_dialect now accepts the same keyword dialect specifications
2736 as the reader and writer, allowing the user to register dialects
2737 without first creating a dialect class.
2738 + a configurable limit to the size of parsed fields has been added -
2739 previously, an unmatched quote character could result in the entire
2740 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002741 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002742 the parser field size limit (returning the former limit). The initial
2743 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002744 + A line_num attribute has been added to the reader object, which tracks
2745 the number of lines read from the source iterator. This is not
2746 the same as the number of records returned, as records can span
2747 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002748 + reader and writer objects were not being registered with the cyclic-GC.
2749 This has been fixed.
2750
Brett Cannone6539c42005-01-08 02:43:53 +00002751- _DummyThread objects in the threading module now delete self.__block that is
2752 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2753 lock primitives tend to be limited in number and thus should not be wasted on
2754 a _DummyThread object. Fixes bug #1089632.
2755
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002756- The imghdr module now detects Exif files.
2757
Raymond Hettinger6065d322004-12-20 23:51:53 +00002758- StringIO.truncate() now correctly adjusts the size attribute.
2759 (Bug #951915).
2760
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002761- locale.py now uses an updated locale alias table (built using
2762 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2763 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002764 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002765
Raymond Hettinger3557f422004-12-07 12:02:02 +00002766- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2767
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002768- the pickle module no longer accepts the deprecated None option in the
2769 args tuple returned by __reduce__().
2770
Brett Cannon84667c02004-12-07 03:25:18 +00002771- optparse now optionally imports gettext. This allows its use in setup.py.
2772
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002773- the pickle module no longer uses the deprecated bin parameter.
2774
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002775- the shelve module no longer uses the deprecated binary parameter.
2776
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002777- the pstats module no longer uses the deprecated ignore() method.
2778
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002779- the filecmp module no longer uses the deprecated use_statcache argument.
2780
Raymond Hettinger664347b2004-12-04 21:21:53 +00002781- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2782 extended or overridden by subclasses. Formerly, the subclassed method would
2783 be ignored by the rest of the module. (Bug #1078905).
2784
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002785- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002786 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002787
Walter Dörwald36733692004-12-22 12:50:50 +00002788- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2789 once when a size argument is given. This prevents a buffer overflow in the
2790 tokenizer with very long source lines.
2791
Barry Warsaw538561e2006-01-01 21:48:54 +00002792- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2793 immediately after creating the object, without any intervening
2794 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002795
Skip Montanaro05885812005-01-16 20:48:27 +00002796- The reconvert.quote function can now emit triple-quoted strings. The
2797 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002798
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002799- ``UserString.MutableString`` now supports negative indices in
2800 ``__setitem__`` and ``__delitem__``
2801
Greg Ward40407942005-03-05 02:53:17 +00002802- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2803 correctly.
2804
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002805- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2806 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2807 character even if the user has passed a size parameter to get a proper
2808 line ending. Remove the special handling of a "\r\n" that has been split
2809 between two lines.
2810
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002811- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2812 about illegal code points. The codec now supports PEP 293 style error
2813 handlers.
2814
Walter Dörwald78a78b02005-09-01 12:04:29 +00002815- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002816 from the input stream, so that the output is a byte string in the correct
2817 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002818
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002819- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2820 considering it exactly like a '*'.
2821
Walter Dörwald007f8df2005-10-09 19:42:27 +00002822- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2823 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002824
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002825- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2826
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002827- Patch #1413711: Certain patterns of differences were making difflib
2828 touch the recursion limit.
2829
Walter Dörwald58917a62006-03-31 15:26:22 +00002830- Bug #947906: An object oriented interface has been added to the calendar
2831 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002832 called as a script (e.g. via ``python -mcalendar``). Localized month and
2833 weekday names can be ouput (even if an exotic encoding is used) using

2837-----
2838
Neal Norwitz602d3392006-03-31 08:21:40 +00002839- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2840 by using -mieee gcc option.
2841

2843
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002844- Build support for Win64-AMD64 was added.
2845
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002846- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2847
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002848- Patch #881820: look for openpty and forkpty also in libbsd.
2849
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002850- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2851 The zlib module is now builtin on Windows.
2852
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002853- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2854
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002855- Bug #1189330: configure did not correctly determine the necessary
2856 value of LINKCC if python was built with GCC 4.0.
2857
Trent Mick8321b422005-07-26 02:29:21 +00002858- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2859 vulnerability in zlib 1.2.1 and 1.2.2.
2860
Brett Cannon08cd5982005-04-24 22:26:38 +00002861- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2862 flags that change binary compatibility. Changes were also made to
2863 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002864 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002865
Bob Ippolitoed233462005-03-29 13:47:59 +00002866- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2867 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2868 no longer exists). This configure patch makes things right.
2869
Martin v. Löwise2713be2005-03-08 15:03:08 +00002870- Bug #1158607: Build with --disable-unicode again.
2871
Brett Cannon46d96232005-02-16 00:07:19 +00002872- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2873 defined. Discovered as a result of not being able to build on OS X.
2874
Brett Cannon516592f2004-12-07 00:42:59 +00002875- setup.py now uses the directories specified in LDFLAGS using the -L option
2876 and in CPPFLAGS using the -I option for adding library and include
2877 directories, respectively, for compiling extension modules against. This has
2878 led to the core being compiled using the values in CPPFLAGS. It also removes
2879 the need for the special-casing of both DarwinPorts and Fink for darwin since
2880 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2881 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2882 Fink, ``-I/opt/local/include`` for DarwinPorts).
2883
Brett Cannon43802422005-02-10 20:48:03 +00002884- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2885 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2886 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2887 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002889C API
2890-----
2891
Tim Petersc9d78aa2006-03-26 23:27:58 +00002892- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2893 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2894 is obtained via the ``PyObject_`` family, it must be released via the
2895 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2896 always been officially true, but when Python's small-object allocator was
2897 introduced, an attempt was made to cater to a few extension modules
2898 discovered at the time that obtained memory via ``PyObject_New`` but
2899 released it via ``PyMem_DEL``. It's years later, and if such code still
2900 exists it will fail now (probably with segfaults, but calling wrong
2901 low-level memory management functions can yield many symptoms).
2902
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002903- Added a C API for set and frozenset objects.
2904
Raymond Hettinger66517482004-12-03 11:45:13 +00002905- Removed PyRange_New().
2906
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002907- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2908 mapping argument now. This string is used as a mapping table. Byte values
2909 greater than the length of the string and 0xFFFE are treated as undefined
2910 mappings.

2915
Martin v. Löwis4d394df2005-01-23 09:19:22 +00002916- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002917
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002918- Patch #1276356: New resource "urlfetch" is implemented. This enables
2919 even impatient people to run tests that require remote files.
