702
Neal Norwitz0bcafac2006-09-11 08:51:17 +0000703- Make _PyGILState_NoteThreadState() static, it was not used anywhere
704 outside of pystate.c and should not be necessary.
705
Brett Cannon19d76c52006-09-09 07:18:44 +0000706- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This

726
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000727- Bug #1520864: unpacking singleton tuples in list comprehensions and

Guido van Rossumc69ac252006-08-10 18:09:25 +0000837What's New in Python 2.5 release candidate 1?

842Core and builtins
843-----------------
844
Neal Norwitz24b6f202006-09-05 04:43:56 +0000845- Fix infinite recursion when subclassing long and overriding __hash__.
846
847- Fix concatenation (+=) of long strings.
848
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000849- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000850 compared equal or unequal to a string and a UnicodeDecodeError
851 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000852
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000853 Instead, the equal (==) and unequal (!=) comparison operators will
854 now issue a UnicodeWarning and interpret the two objects as
855 unequal. The UnicodeWarning can be filtered as desired using
856 the warning framework, e.g. silenced completely, turned into an
857 exception, logged, etc.
858
859 Note that compare operators other than equal and unequal will still
860 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000861
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000862- Fix segfault when doing string formatting on subclasses of long.
863
864- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
865 with new-style classes.
866
867- Fix bug related to __len__ functions returning negative values with
868 classic classes.
869
870- Patch #1538606, Fix __index__() clipping. There were some problems
871 discovered with the API and how integers that didn't fit into Py_ssize_t
872 were handled. This patch attempts to provide enough alternatives
873 to effectively use __index__.
874
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000875- Bug #1536021: __hash__ may now return long int; the final hash
876 value is obtained by invoking hash on the long int.
877
Thomas Hellerab1049c2006-08-08 17:37:00 +0000878- Bug #1536786: buffer comparison could emit a RuntimeWarning.

Thomas Heller74d36f02006-08-04 18:17:40 +0000883- On Windows, the PyErr_Warn function is now exported from
884 the Python dll again.
885
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000886- Bug #1191458: tracing over for loops now produces a line event
887 on each iteration. Fixing this problem required changing the .pyc
888 magic number. This means that .pyc files generated before 2.5c1
889 will be regenerated.
890
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000891- Bug #1333982: string/number constants were inappropriately stored
892 in the byte code and co_consts even if they were not used, ie
893 immediately popped off the stack.
894
Georg Brandle9462c72006-08-04 18:03:37 +0000895- Fixed a reference-counting problem in property().

899-------
900
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000901- Fix a bug in the ``compiler`` package that caused invalid code to be
902 generated for generator expressions.
903
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000904- The distutils version has been changed to 2.5.0. The change to
905 keep it programmatically in sync with the Python version running
906 the code (introduced in 2.5b3) has been reverted. It will continue
907 to be maintained manually as static string literal.
908
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000909- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000910 and this cannot be converted to the required C type, an exception is
911 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000912 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000913
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000914- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000915 an exception.
916
Tim Peterscbdd3502006-09-05 01:47:53 +0000917- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000918 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000919 workarounds for clocks with low resolution, to stop the code yielding
920 duplicate UUIDs.
921
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000922- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
923 before raising SystemExit, allowing IDLE to honor quit() and exit().
924
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000925- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
926
Georg Brandl7a1af772006-08-14 21:55:28 +0000927- Patch #1536071: trace.py should now find the full module name of a
928 file correctly even on Windows.
929
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000930- logging's atexit hook now runs even if the rest of the module has
931 already been cleaned up.
932
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000933- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000934
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000935- Bug #1531405, format_exception no longer raises an exception if
936 str(exception) raised an exception.
937
Neil Schemenauer06ded092006-08-04 16:20:30 +0000938- Fix a bug in the ``compiler`` package that caused invalid code to be
939 generated for nested functions.

950 raises the correct exceptions.
951
Thomas Heller1ce433e2006-08-14 16:20:04 +0000952- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
953 '-no-stack-protector' compiler flag for OpenBSD has been removed.
954
Thomas Heller86720042006-08-14 11:17:48 +0000955- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
956 uses the _as_parameter_ attribute when objects are passed to foreign
957 function calls. The ctypes version number was changed to 1.0.1.
958
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000959- Bug #1530559, struct.pack raises TypeError where it used to convert.
960 Passing float arguments to struct.pack when integers are expected
961 now triggers a DeprecationWarning.
962
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000963

985-----
986
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +0000987- Bug #1535502, build _hashlib on Windows, and use masm assembler
988 code in OpenSSL.
989
Thomas Hellerdb7b4432006-08-04 19:49:31 +0000990- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

996-----
997
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000998- New API for Unicode rich comparisons: PyUnicode_RichCompare()
999
Tim Peters4643c2f2006-08-10 22:45:34 +00001000- Bug #1069160. Internal correctness changes were made to
1001 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1002 the documentation was changed to state that the return value
1003 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001006What's New in Python 2.5 beta 3?
1007================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001008
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001009*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001010
1011Core and builtins
1012-----------------
1013
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001014- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001015 returned a long (see PEP 353).
1016
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001017- Bug #1515471: string.replace() accepts character buffers again.
1018
Neal Norwitz07aadb12006-07-30 06:55:48 +00001019- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1020 This provides the proper warning for struct.pack().
1021 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1022
Neal Norwitz0d62a062006-07-30 06:53:31 +00001023- Patch #1531113: Fix augmented assignment with yield expressions.
1024 Also fix a SystemError when trying to assign to yield expressions.
1025
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001026- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1027 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1028 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1029 excessive filesystem operations during imports.
1030
Tim Petersbc24eee2006-07-27 01:14:53 +00001031- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1032 operations on signed longs that are formally undefined by C.
1033 Unfortunately, at least one compiler now cares about that, so complicated
1034 the code to make that compiler happy again.
1035
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001036- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1037
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001038- Patch #1232023: Stop including current directory in search
1039 path on Windows.
1040
Neal Norwitze1fdb322006-07-21 05:32:28 +00001041- Fix some potential crashes found with failmalloc.
1042
Neal Norwitze7563102006-07-17 01:00:16 +00001043- Fix warnings reported by Klocwork's static analysis tool.
1044
Neal Norwitz84be93b2006-07-16 01:50:38 +00001045- Bug #1512814, Fix incorrect lineno's when code within a function
1046 had more than 255 blank lines.
1047
Georg Brandl9dceedb2006-07-12 15:31:17 +00001048- Patch #1521179: Python now accepts the standard options ``--help`` and
1049 ``--version`` as well as ``/?`` on Windows.
1050
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001051- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001052 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001053 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001054
Tim Peters112aad32006-07-19 00:03:19 +00001055- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001056 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001057 new ``sys._current_frames()`` returns a dictionary with one entry,
1058 mapping the faux "thread id" 0 to the current frame.
1059
Ronald Oussoren3075e162006-07-25 20:28:55 +00001060- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001061
Ronald Oussoren3075e162006-07-25 20:28:55 +00001062
Neal Norwitza1f10902006-07-12 07:28:29 +00001063Library
1064-------
1065
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001066- Correction of patch #1455898: In the mbcs decoder, set final=False
1067 for stream decoder, but final=True for the decode function.
1068
Georg Brandl07fec3a2006-08-01 18:49:24 +00001069- os.urandom no longer masks unrelated exceptions like SystemExit or
1070 KeyboardInterrupt.
1071
Tim Peters4643c2f2006-08-10 22:45:34 +00001072- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001073 shutil.copytree on Windows
1074
Georg Brandle34ac7c2006-07-30 11:07:23 +00001075- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1076 refers to file descriptors, not file objects.
1077
Tim Peterscbdd3502006-09-05 01:47:53 +00001078- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001079 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001080 #1513611, and probably others.
1081
Georg Brandledd9b0d2006-07-29 09:33:26 +00001082- Bug #1441397: The compiler module now recognizes module and function
1083 docstrings correctly as it did in Python 2.4.
1084
Tim Peters6f681472006-07-27 23:44:37 +00001085- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1086 lost that tests are sorted by name before being run. This rarely
1087 matters for well-written tests, but can create baffling symptoms if
1088 side effects from one test to the next affect outcomes. ``DocTestFinder``
1089 has been changed to sort the list of tests it returns.
1090
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001091- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001092 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001093
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001094- Bug #978833: Really close underlying socket in _socketobject.close.
1095
Georg Brandldb232dc2006-08-20 13:15:43 +00001096- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1097 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001098
Georg Brandlcf0c1722006-07-26 07:23:32 +00001099- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1100 to recursive calls and call it with the failing package name.
1101
Martin v. Löwis0b483032006-07-25 09:53:12 +00001102- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1103
Georg Brandlc13c34c2006-07-24 14:09:56 +00001104- Patch #1515343: Fix printing of deprecated string exceptions with a
1105 value in the traceback module.
1106
Greg Ward48fae7a2006-07-23 16:05:51 +00001107- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1108
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001109- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1110
Brett Cannoncaebe222006-07-18 04:41:36 +00001111- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1112 argument tuple. For arguments where zero is illegal, the value is forced to
1113 the minimum value that is correct. This is to support an undocumented but
1114 common way people used to fill in inconsequential information in the time
1115 tuple pre-2.4.
1116
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001117- Patch #1220874: Update the binhex module for Mach-O.
1118
Barry Warsawb110bad2006-07-21 14:51:07 +00001119- The email package has improved RFC 2231 support, specifically for
1120 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1121 (name*0=<blah>) parameter continuations. This may change the types of
1122 values returned from email.message.Message.get_param() and friends.
1123 Specifically in some cases where non-encoded continuations were used,
1124 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1125 will just return the string (since non-encoded continuations don't have
1126 charset and language parts).
1127
1128 Also, whereas % values were decoded in all parameter continuations, they are
1129 now only decoded in encoded parameter parts.
1130
Ronald Oussoren3075e162006-07-25 20:28:55 +00001131- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1132
1133- Bug #1517996: IDLE now longer shows the default Tk menu when a
1134 path browser, class browser or debugger is the frontmost window on MacOS X
1135
Barry Warsaw00decd72006-07-27 23:43:15 +00001136- Patch #1520294: Support for getset and member descriptors in types.py,
1137 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1138 of an object against these built-in types and more importantly, for getting
1139 their docstrings printed in the interactive interpreter's help() function.

1143-----------------
1144
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001145- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1146 a socket operation on a socket with a timeout, the exception will be
1147 caught correctly. Previously, the exception was not caught.
1148
Thomas Heller1393d6a2006-07-28 21:43:20 +00001149- Patch #1529514: The _ctypes extension is now compiled on more
1150 openbsd target platforms.
1151
Tim Peters9cab5932006-07-28 00:30:00 +00001152- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1153 a memory leak, affecting pickles and deep copies.
1154
Tim Petersbc24eee2006-07-27 01:14:53 +00001155- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001156 Paul Eggert.
1157
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001158- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1159
Thomas Hellerce049a02006-07-14 17:51:14 +00001160- Patch #1521817: Index range checking on ctypes arrays containing
1161 exactly one element enabled again. This allows iterating over these
1162 arrays, without the need to check the array size before.
1163
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001164- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001165 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001166 /dev/null in certain cases; this is now fixed.
1167
Thomas Heller47d7a062006-07-12 08:43:47 +00001168- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1169 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001170
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001171- Because of a misspelled preprocessor symbol, ctypes was always
1172 compiled without thread support; this is now fixed.
1173
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001174- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1175 methods now allow their database parameter to be None as the
1176 sleepycat API allows.
1177
Matt Flemingec926502006-07-28 11:27:27 +00001178- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1179 bluetooth API compared with Linux and FreeBSD.
1180
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001181Tests
1182-----
1183
1184- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1185 how long the test file should take to play. Now accepts taking 2.93 secs
1186 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1187
Georg Brandl4793aa32006-07-28 18:31:39 +00001188- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1189 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1190 run via ``regrtest.py``. Now they do.

Martin v. Löwis0907f4d2006-07-30 14:09:47 +00001192Build
1193-----
1194
1195- Bug #1439538: Drop usage of test -e in configure as it is not portable.
1196
Ronald Oussoren26cad082006-08-01 21:00:57 +00001197Mac
1198---
1199
1200- PythonLauncher now works correctly when the path to the script contains
1201 characters that are treated specially by the shell (such as quotes).
1202
1203- Bug #1527397: PythonLauncher now launches scripts with the working directory
1204 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001205 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001206 expect.

Georg Brandlad29e632006-06-21 17:45:17 +00001213
1214Core and builtins
1215-----------------
1216
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001217- Bug #1441486: The literal representation of -(sys.maxint - 1)
1218 again evaluates to a int object, not a long.
1219
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001220- Bug #1501934: The scope of global variables that are locally assigned
1221 using augmented assignment is now correctly determined.
1222
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001223- Bug #927248: Recursive method-wrapper objects can now safely
1224 be released.
1225
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001226- Bug #1417699: Reject locale-specific decimal point in float()
1227 and atof().
1228
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001229- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1230 omit a default "error" argument for NULL pointer. This allows
1231 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001232
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001233- Bug #1519018: 'as' is now validated properly in import statements.
1234
Neal Norwitz28746ab2006-07-09 22:14:42 +00001235- On 64 bit systems, int literals that use less than 64 bits are
1236 now ints rather than longs.
1237
Neal Norwitzed657552006-07-10 00:04:44 +00001238- Bug #1512814, Fix incorrect lineno's when code at module scope
1239 started after line 256.
1240
Tim Peters32a83612006-07-10 21:08:24 +00001241- New function ``sys._current_frames()`` returns a dict mapping thread
1242 id to topmost thread stack frame. This is for expert use, and is
1243 especially useful for debugging application deadlocks. The functionality
1244 was previously available in Fazal Majid's ``threadframe`` extension
1245 module, but it wasn't possible to do this in a wholly threadsafe way from
1246 an extension.
1247

1250
Martin v. Löwis77621582006-07-30 13:27:31 +00001251- Bug #1257728: Mention Cygwin in distutils error message about a missing
1252 VS 2003.
1253
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001254- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1255
Tim Peters32a83612006-07-10 21:08:24 +00001256- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001257 environment variable to be set in order to the SDK environment
1258 for finding the compiler, include files, etc.
1259

1261
Nick Coghlan2d792252006-07-06 13:47:18 +00001262- warnings.py now ignores ImportWarning by default
1263
Thomas Woutersadd19112006-07-05 11:03:49 +00001264- string.Template() now correctly handles tuple-values. Previously,
1265 multi-value tuples would raise an exception and single-value tuples would
1266 be treated as the value they contain, instead.
1267
Martin v. Löwisede77f52006-07-03 13:01:35 +00001268- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1269 even if some data are received.
1270
Martin v. Löwis45482392006-07-03 12:28:58 +00001271- Bug #1267547: Put proper recursive setup.py call into the
1272 spec file generated by bdist_rpm.
1273
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001274- Bug #1514693: Update turtle's heading when switching between
1275 degrees and radians.
1276
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001277- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001278 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001279
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001280- Bug #1514703: Only setup canvas window in turtle when the canvas
1281 is created.
1282
Martin v. Löwis7596e832006-07-01 15:33:37 +00001283- Bug #1513223: .close() of a _socketobj now releases the underlying
1284 socket again, which then gets closed as it becomes unreferenced.

1287 attribute values.
1288
1289- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1290 sgmllib ('[' and ']' were not accepted).
1291
Georg Brandl1be63af2006-06-28 20:23:25 +00001292- Fix a bug in the turtle module's end_fill function.
1293
Brett Cannon53ab5b72006-06-22 16:49:14 +00001294- Bug #1510580: The 'warnings' module improperly required that a Warning
1295 category be either a types.ClassType and a subclass of Warning. The proper
1296 check is just that it is a subclass with Warning as the documentation states.
1297
Georg Brandlad29e632006-06-21 17:45:17 +00001298- The compiler module now correctly compiles the new try-except-finally
1299 statement (bug #1509132).
1300
Neal Norwitz60373cd2006-06-22 06:30:50 +00001301- The wsgiref package is now installed properly on Unix.
1302
Vinay Sajip28e57612006-07-01 10:45:20 +00001303- A bug was fixed in logging.config.fileConfig() which caused a crash on
1304 shutdown when fileConfig() was called multiple times.
1305
Gerhard Häring762fbd32006-07-02 17:48:30 +00001306- The sqlite3 module did cut off data from the SQLite database at the first
1307 null character before sending it to a custom converter. This has been fixed
1308 now.
1309
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001310Extension Modules
1311-----------------
1312
Tim Peters112aad32006-07-19 00:03:19 +00001313- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1314 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1315 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001316
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001317- Assigning None to pointer type fields in ctypes structures possible
1318 overwrote the wrong fields, this is fixed now.
1319
1320- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1321 on non-Windows platforms.
1322
1323- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1324 integer or long, without range checking.
1325
1326- Patch #1517790: It is now possible to use custom objects in the ctypes
1327 foreign function argtypes sequence as long as they provide a from_param
1328 method, no longer is it required that the object is a ctypes type.
1329
1330- The '_ctypes' extension module now works when Python is configured
1331 with the --without-threads option.
1332
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001333- Bug #1513646: os.access on Windows now correctly determines write
1334 access, again.
1335
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001336- Bug #1512695: cPickle.loads could crash if it was interrupted with
1337 a KeyboardInterrupt.
1338
Neal Norwitza12aa882006-07-06 06:45:08 +00001339- Bug #1296433: parsing XML with a non-default encoding and
1340 a CharacterDataHandler could crash the interpreter in pyexpat.
1341
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001342- Patch #1516912: improve Modules support for OpenVMS.
1343
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001344Build
1345-----
1346
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001347- Automate Windows build process for the Win64 SSL module.
1348
Tim Peters32a83612006-07-10 21:08:24 +00001349- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001350 Previously, the slight difference could cause compilation errors of the
1351 'zlib' module on systems with more than one version of zlib.
1352
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001353- The MSI compileall step was fixed to also support a TARGETDIR
1354 with spaces in it.
1355
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001356- Bug #1517388: sqlite3.dll is now installed on Windows independent
1357 of Tcl/Tk.
1358
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001359- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001360 trying to be installed even though it's empty.
Georg Brandlad29e632006-06-21 17:45:17 +00001361
Neal Norwitzb15ac312006-06-29 04:10:08 +00001362Tests
1363-----
1364
1365- Call os.waitpid() at the end of tests that spawn child processes in order
1366 to minimize resources (zombies).
1367
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001368Documentation
1369-------------
1370
Nick Coghlan2d792252006-07-06 13:47:18 +00001371- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1372 documentation for the warnings module.
1373
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001374- Patch #1509163: MS Toolkit Compiler no longer available.
1375

Nick Coghlanc649ec52006-05-29 12:43:05 +00001379What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +00001380================================
Anthony Baxter51bcb682006-04-05 14:51:42 +00001381
Anthony Baxterd1136802006-06-19 12:04:15 +00001382*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +00001383
1384Core and builtins
1385-----------------
1386
Georg Brandla56b9152006-06-19 06:35:54 +00001387- Patch #1507676: Error messages returned by invalid abstract object operations
1388 (such as iterating over an integer) have been improved and now include the
1389 type of the offending object to help with debugging.
1390
Brett Cannonea3912b2006-06-13 21:46:41 +00001391- Bug #992017: A classic class that defined a __coerce__() method that returned
1392 its arguments swapped would infinitely recurse and segfault the interpreter.
1393
Neal Norwitz909eb122006-06-12 02:13:21 +00001394- Fix the socket tests so they can be run concurrently.
1395
Neal Norwitzb9845e72006-06-12 02:11:18 +00001396- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001397 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001398
Brett Cannon22565aa2006-06-09 22:31:23 +00001399- Bug #532646: object.__call__() will continue looking for the __call__
1400 attribute on objects until one without one is found. This leads to recursion
1401 when you take a class and set its __call__ attribute to an instance of the
1402 class. Originally fixed for classic classes, but this fix is for new-style.
1403 Removes the infinite_rec_3 crasher.
1404
Georg Brandl24250812006-06-09 18:45:48 +00001405- The string and unicode methods startswith() and endswith() now accept
1406 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1407
Brett Cannonde3b0522006-06-08 17:00:45 +00001408- Buffer objects, at the C level, never used the char buffer
1409 implementation even when the char buffer for the wrapped object was
1410 explicitly requested (originally returned the read or write buffer).
1411 Now a TypeError is raised if the char buffer is not present but is
1412 requested.
1413
Georg Brandlddbaa662006-06-04 21:56:52 +00001414- Patch #1346214: Statements like "if 0: suite" are now again optimized
1415 away like they were in Python 2.4.
1416
Georg Brandlb7c8f542006-05-27 12:30:25 +00001417- Builtin exceptions are now full-blown new-style classes instead of
1418 instances pretending to be classes, which speeds up exception handling
1419 by about 80% in comparison to 2.5a2.
1420
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001421- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1422 Unicode 4.1.
1423
Georg Brandlf4ef1162006-05-26 18:03:31 +00001424- Patch #921466: sys.path_importer_cache is now used to cache valid and
1425 invalid file paths for the built-in import machinery which leads to
1426 fewer open calls on startup.
1427
Tim Peters696cf432006-05-24 21:10:40 +00001428- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1429 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1430 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1431 the number of input digits (it was and remains linear-time for bases
1432 2, 4, 8, 16 and 32).
1433
Tim Petersb713ec22006-05-23 18:45:30 +00001434- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1435 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1436 an integer close to ``sys.maxint``. This was repaired by patch
1437 #1335972, which also gives a nice speedup.
1438
Richard Jonescebbefc2006-05-23 18:28:17 +00001439- Patch #1337051: reduced size of frame objects.
1440
1441- PyErr_NewException now accepts a tuple of base classes as its
1442 "base" parameter.
1443
Richard Jones7c88dcc2006-05-23 10:37:38 +00001444- Patch #876206: function call speedup by retaining allocated frame
1445 objects.
1446
Georg Brandl7b90e162006-05-18 07:01:27 +00001447- Bug #1462152: file() now checks more thoroughly for invalid mode
1448 strings and removes a possible "U" before passing the mode to the
1449 C library function.
1450
Neal Norwitz1004a532006-05-15 07:17:23 +00001451- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1452
Neal Norwitz373f0a72006-05-15 07:04:36 +00001453- Bug #1487966: Fix SystemError with conditional expression in assignment
1454
Martin v. Löwis879768d2006-05-11 13:28:43 +00001455- WindowsError now has two error code attributes: errno, which carries
1456 the error values from errno.h, and winerror, which carries the error
1457 values from winerror.h. Previous versions put the winerror.h values
1458 (from GetLastError()) into the errno attribute.
1459
Martin v. Löwis77736712006-05-04 05:51:03 +00001460- Patch #1475845: Raise IndentationError for unexpected indent.
1461
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001462- Patch #1479181: split open() and file() from being aliases for each other.
1463
Tim Peters44bd9862006-06-01 13:49:23 +00001464- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1465 methods were always silently ignored by dictionaries when comparing keys.
1466 They are now passed through (except when using the C API function
1467 ``PyDict_GetItem()``, whose semantics did not change).
1468
1469- Bug #1456209: In some obscure cases it was possible for a class with a
1470 custom ``__eq__()`` method to confuse dict internals when class instances
1471 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1472 No, you don't have any code that did this ;-)

1475-----------------
1476
Trent Mick960a3f82006-06-28 20:30:41 +00001477- Bug #1295808: expat symbols should be namespaced in pyexpat
1478
1479- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1480
Brett Cannon6ee7d012006-06-08 16:23:04 +00001481- Change binascii.hexlify to accept a read-only buffer instead of only a char
1482 buffer and actually follow its documentation.
1483
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001484- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1485
Nick Coghlanc649ec52006-05-29 12:43:05 +00001486- Patch #1478788 (modified version): The functional extension module has
1487 been renamed to _functools and a functools Python wrapper module added.
1488 This provides a home for additional function related utilities that are
1489 not specifically about functional programming. See PEP 309.
1490
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001491- Patch #1493701: performance enhancements for struct module.
1492
Georg Brandl378d5922006-05-17 14:26:50 +00001493- Patch #1490224: time.altzone is now set correctly on Cygwin.
1494
Georg Brandl8d3342b2006-05-16 07:38:27 +00001495- Patch #1435422: zlib's compress and decompress objects now have a
1496 copy() method.
1497
Andrew MacIntyre92913322006-06-13 15:04:24 +00001498- Patch #1454481: thread stack size is now tunable at runtime for thread
1499 enabled builds on Windows and systems with Posix threads support.
1500
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001501- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1502 (up to the system limit of 32K characters).
1503
1504- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1505 As a result, these functions now raise WindowsError instead of OSError.
1506
Tim Peters7a822da2006-05-25 21:50:17 +00001507- ``time.clock()`` on Win64 should use the high-performance Windows
1508 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1509 Windows platforms).
1510
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001511- Calling Tk_Init twice is refused if the first call failed as that
1512 may deadlock.
1513
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001514- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1515 accept it without potentially using an uninitialized pointer.
1516
1517- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1518 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1519 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001520
Gregory P. Smith372b5832006-06-05 18:48:21 +00001521- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001522 [pybsddb project SF patch number 1466734]
1523
Gregory P. Smith372b5832006-06-05 18:48:21 +00001524- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1525 parameter is supplied. [SF pybsddb bug #1477863]
1526
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001527- bsddb: the __len__ method of a DB object has been fixed to return correct
1528 results. It could previously incorrectly return 0 in some cases.
1529 Fixes SF bug 1493322 (pybsddb bug 1184012).
1530
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001531- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1532 aborts the db transaction safely when a modifier callback fails.
1533 Fixes SF python patch/bug #1408584.
1534
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001535- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001536 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001537 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1538 database calls that would previously deadlock. [SF python bug #775414]
1539
Vinay Sajip28e57612006-07-01 10:45:20 +00001540- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001541
Walter Dörwald4994d952006-06-19 08:07:50 +00001542- Patch #1506645: add Python wrappers for the curses functions
1543 is_term_resized, resize_term and resizeterm.

Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001548- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1549 functions.
1550
Martin v. Löwis3798da02006-06-17 18:44:27 +00001551- Patch #812986: Update turtle output even if not tracing.
1552
Vinay Sajip28e57612006-07-01 10:45:20 +00001553- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001554 Tkinter.BaseWidget.
1555
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001556- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1557
Martin v. Löwis337487e2006-06-17 09:15:14 +00001558- Patch #763580: Add name and value arguments to Tkinter variable
1559 classes.
1560
Georg Brandl83cc0d02006-06-14 08:50:03 +00001561- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1562 mime.types file for determining MIME types.
1563
Georg Brandl2605ca82006-06-14 06:08:31 +00001564- Bug #1339007: Shelf objects now don't raise an exception in their
1565 __del__ method when initialization failed.
1566
Martin v. Löwisd8251432006-06-14 05:21:04 +00001567- Patch #1455898: The MBCS codec now supports the incremental mode for
1568 double-byte encodings.
1569
Tim Peters43898b42006-06-14 04:09:25 +00001570- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1571 guarantee that adjacent triples in the return list always describe
1572 non-adjacent blocks. Previously, a pair of matching blocks could end
1573 up being described by multiple adjacent triples that formed a partition
1574 of the matching pair.
1575
Greg Ward0e0c9f42006-06-11 16:24:11 +00001576- Bug #1498146: fix optparse to handle Unicode strings in option help,
1577 description, and epilog.
1578
Greg Wardd1c797e2006-06-11 14:42:41 +00001579- Bug #1366250: minor optparse documentation error.
1580
Greg Ward7f547402006-06-11 00:40:49 +00001581- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1582 clarify docs.
1583
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001584- The wsgiref package has been added to the standard library.
1585
Nick Coghlan676725d2006-06-08 13:54:49 +00001586- The functions update_wrapper() and wraps() have been added to the functools
1587 module. These make it easier to copy relevant metadata from the original
1588 function when writing wrapper functions.
1589
Tim Petersd6a9eef2006-06-05 01:48:21 +00001590- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1591 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001592
Martin v. Löwis3f767792006-06-04 19:36:28 +00001593- Patch #1359618: Speed up charmap encoder by using a trie structure
1594 for lookup.
1595
Tim Petersd609b1a2006-06-02 23:22:51 +00001596- The functions in the ``pprint`` module now sort dictionaries by key
1597 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1598 if and only if its display required more than one line, although that
1599 wasn't documented. The new behavior increases predictability; e.g.,
1600 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1601
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001602- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1603 (thanks for J. J. Lee).
1604
Georg Brandl2b330372006-05-28 20:23:12 +00001605- Patch #1496206: improve urllib2 handling of passwords with respect to
1606 default HTTP and HTTPS ports.
1607
George Yoshidaf3c65de2006-05-28 16:39:09 +00001608- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1609
Bob Ippolito7298f272006-05-23 18:43:47 +00001610- Patch #1281707: speed up gzip.readline.
1611
Georg Brandlb89316f2006-05-17 15:51:16 +00001612- Patch #1180296: Two new functions were added to the locale module:
1613 format_string() to get the effect of "format % items" but locale-aware,
1614 and currency() to format a monetary number with currency sign.
1615
Georg Brandle3a25832006-05-17 14:56:04 +00001616- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1617 and several features added, such as speed and geometry control.
1618
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001619- Patch #1488881: add support for external file objects in bz2 compressed
1620 tarfiles.
1621
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001622- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1623 stdout arguments, making it possible to redirect input and output
1624 for remote debugging.
1625
1626- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1627 a couple of issues, notably handling of long file names using the
1628 GNU LONGNAME extension.
1629
1630- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1631 new flag when ``name`` is already the name of an option flag.
1632
1633- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1634 package.
1635
1636- Patch #1472854: make the rlcompleter.Completer class usable on non-
1637 UNIX platforms.
1638
1639- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1640
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001641- Bug #1472827: correctly escape newlines and tabs in attribute values in

1677Core and builtins
1678-----------------
1679
Thomas Heller1b046642006-04-18 18:51:06 +00001680- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1681 by converting these apis from macros into exported functions again:
1682
1683 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1684 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1685 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1686 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1687 PyRun_String Py_CompileString
1688
Martin v. Löwis45294a92006-04-18 06:24:08 +00001689- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1690
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001691- All uses of PyStructSequence_InitType have been changed to initialize
1692 the type objects only once, even if the interpreter is initialized
1693 multiple times.
1694
Neal Norwitz61546162006-04-14 05:20:28 +00001695- Bug #1454485, array.array('u') could crash the interpreter. This was
1696 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1697 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1698
1699- Py_UNICODE is unsigned. It was always documented as unsigned, but
1700 due to a bug had a signed value in previous versions.
1701
Tim Peters3a5e8b12006-04-11 01:44:07 +00001702- Patch #837242: ``id()`` of any Python object always gives a positive
1703 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1704 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001705 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001706 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001707
Tim Peters3a5e8b12006-04-11 01:44:07 +00001708 def __hash__(self):
1709 return id(self) # WRONG
1710
1711 because a hash result must be a (short) Python int but it was always
1712 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001713 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001714 was always usable as a hash value before this patch. That's no longer
1715 necessarily so.
1716
1717- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001718 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001719 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001720 #1454844)
1721
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001722- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1723 involving generators that have paused outside of any ``try`` or ``with``
1724 blocks. (In 2.5a1, a paused generator that was part of a reference
1725 cycle could not be garbage collected, regardless of whether it was
1726 paused in a ``try`` or ``with`` block.)

1733
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001734- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1735 fails with an error condition.
1736
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001737- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1738
1739- Bug #1117761: bsddb.*open() no longer raises an exception when using
1740 the cachesize parameter.
1741
1742- Bug #1149413: bsddb.*open() no longer raises an exception when using
1743 a temporary db (file=None) with the 'n' flag to truncate on open.
1744
1745- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1746 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001747
Armin Rigoa9017c32006-04-19 11:50:27 +00001748- Patch #1062014: AF_UNIX sockets under Linux have a special
1749 abstract namespace that is now fully supported.

1752-------
1753
Peter Astrand7d1d4362006-07-14 14:04:45 +00001754- Bug #1223937: subprocess.CalledProcessError reports the exit status
1755 of the process using the returncode attribute, instead of
1756 abusing errno.
1757
Tim Peters711bf302006-04-25 03:31:36 +00001758- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1759 a doctest to be skipped (the code is not run, and the expected output
1760 or exception is ignored).
1761
Nick Coghlanda2268f2006-04-24 04:37:15 +00001762- Fixed contextlib.nested to cope with exceptions being raised and
1763 caught inside exit handlers.
1764
Greg Wardab05edc2006-04-23 03:47:58 +00001765- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1766 hex, octal, or binary; add ``append_const`` action; keep going if
1767 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1768 added ``epilog`` for better help generation).
1769
Tim Peters21fbd572006-04-21 21:18:10 +00001770- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1771 called from a thread spawned as a side effect of importing a module.
1772
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001773- The pydoc module now supports documenting packages contained in
1774 .zip or .egg files.
1775
1776- The pkgutil module now has several new utility functions, such
1777 as ``walk_packages()`` to support working with packages that are either
1778 in the filesystem or zip files.
1779
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001780- The mailbox module can now modify and delete messages from
1781 mailboxes, in addition to simply reading them. Thanks to Gregory
1782 K. Johnson for writing the code, and to the 2005 Google Summer of
1783 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001784

1796
Phillip J. Eby47032112006-04-11 01:07:43 +00001797- The warnings, linecache, inspect, traceback, site, and doctest modules
1798 were updated to work correctly with modules imported from zipfiles or
1799 via other PEP 302 __loader__ objects.
1800

1807
Skip Montanaro262fb922006-04-21 02:31:07 +00001808- The pstats.Stats class accepts an optional stream keyword argument to
1809 direct output to an alternate file-like object.
1810
Anthony Baxter51bcb682006-04-05 14:51:42 +00001811Build
1812-----
1813
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001814- The Makefile now has a reindent target, which runs reindent.py on
1815 the library.
1816
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001817- Patch #1470875: Building Python with MS Free Compiler
1818
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001819- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001820
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001821- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1822 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001823 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001824 CXX from --with-cxx-main, see description in README.
1825
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001826- Patch #1429775: Link extension modules with the shared libpython.
1827
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001828- Fixed a libffi build problem on MIPS systems.
1829
Tim Peters8931ff12006-05-13 23:28:20 +00001830- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1831 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1832 and "%zu" for unsigned integers of type ``size_t``.
1833
Anthony Baxter51bcb682006-04-05 14:51:42 +00001834Tests
1835-----
1836
Nick Coghlanda2268f2006-04-24 04:37:15 +00001837- test_contextlib now checks contextlib.nested can cope with exceptions
1838 being raised and caught inside exit handlers.
1839
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001840- test_cmd_line now checks operation of the -m and -c command switches
1841
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001842- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1843 it separately and by hand. It also wasn't cleaning up its changes to
1844 the current Decimal context.
1845
Thomas Woutersabd08882006-04-26 15:53:30 +00001846- regrtest.py now has a -M option to run tests that test the new limits of
1847 containers, on 64-bit architectures. Running these tests is only sensible
1848 on 64-bit machines with more than two gigabytes of memory. The argument
1849 passed is the maximum amount of memory for the tests to use.

1858-------------
1859
Tim Petersb06d28c2006-05-12 01:57:59 +00001860- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1861
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001862- PEP 343: Added Context Types section to the library reference
1863 and attempted to bring other PEP 343 related documentation into
1864 line with the implementation and/or python-dev discussions.
1865
Tim Peters8dc73d22006-04-24 02:03:16 +00001866- Bug #1337990: clarified that ``doctest`` does not support examples
1867 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001870What's New in Python 2.5 alpha 1?
1871=================================
1872
Anthony Baxterebed3f62006-04-03 15:03:44 +00001873*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001874
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001875Core and builtins
1876-----------------
1877
Nick Coghlan43832302006-04-23 17:04:07 +00001878- PEP 338: -m command line switch now delegates to runpy.run_module
1879 allowing it to support modules in packages and zipfiles
1880
Martin v. Löwisc661b882006-04-20 04:54:23 +00001881- On Windows, .DLL is not an accepted file name extension for
1882 extension modules anymore; extensions are only found if they
1883 end in .PYD.
1884
Martin v. Löwisea62d252006-04-03 10:56:49 +00001885- Bug #1421664: sys.stderr.encoding is now set to the same value as
1886 sys.stdout.encoding.
1887
Neal Norwitz92e212f2006-04-03 04:48:37 +00001888- __import__ accepts keyword arguments.
1889
Georg Brandlccadf842006-03-31 18:54:53 +00001890- Patch #1460496: round() now accepts keyword arguments.
1891
Anthony Baxter262c00a2006-03-30 10:53:17 +00001892- Fixed bug #1459029 - unicode reprs were double-escaped.
1893
Hye-Shik Changd478f342006-03-23 12:32:36 +00001894- Patch #1396919: The system scope threads are reenabled on FreeBSD
1895 5.4 and later versions.
1896
Neal Norwitze98ccf62006-03-23 05:39:47 +00001897- Bug #1115379: Compiling a Unicode string with an encoding declaration
1898 now gives a SyntaxError.
1899
Georg Brandlabd1ff82006-03-18 07:59:59 +00001900- Previously, Python code had no easy way to access the contents of a
1901 cell object. Now, a ``cell_contents`` attribute has been added
1902 (closes patch #1170323).
1903
Tim Peterscf79aac2006-03-16 01:14:46 +00001904- Patch #1123430: Python's small-object allocator now returns an arena to
1905 the system ``free()`` when all memory within an arena becomes unused
1906 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1907 freed. Some applications will see a drop in virtual memory size now,
1908 especially long-running applications that, from time to time, temporarily
1909 use a large number of small objects. Note that when Python returns an
1910 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001911 platform C library will in turn return that memory to the operating system.
1912 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001913 appears to be effective at least on Microsoft C and gcc-based systems.
1914 Thanks to Evan Jones for hard work and patience.
1915
Georg Brandl533ff6f2006-03-08 18:09:27 +00001916- Patch #1434038: property() now uses the getter's docstring if there is
1917 no "doc" argument given. This makes it possible to legitimately use
1918 property() as a decorator to produce a read-only property.
1919
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001920- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1921 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1922 of requiring an int or long in slicing and a few other contexts, enabling
1923 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1924
Neal Norwitz995acdf2006-03-07 05:01:00 +00001925- Fixed various bugs reported by Coverity's Prevent tool.
1926
Brett Cannonbf364092006-03-01 04:25:17 +00001927- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1928 new exception base class, BaseException, which has a new message attribute.
1929 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1930 Raising a string exception now raises a DeprecationWarning.
1931
Thomas Woutersfb609f42006-02-28 16:37:25 +00001932- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1933 explicitly relative, using 'from .module import name' to mean 'from the same
1934 package as this module is in. Imports without dots still default to the
1935 old relative-then-absolute, unless 'from __future__ import
1936 absolute_import' is used.
1937
Brett Cannona7446e32006-02-27 23:39:10 +00001938- Properly check if 'warnings' raises an exception (usually when a filter set
1939 to "error" is triggered) when raising a warning for raising string
1940 exceptions.
1941
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001942- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001943 The name was removed from Include/code.h.
1944
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001945- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001946
Guido van Rossum1968ad32006-02-25 22:38:04 +00001947- Patch 1433928:
1948 - The copy module now "copies" function objects (as atomic objects).
1949 - dict.__getitem__ now looks for a __missing__ hook before raising
1950 KeyError.
1951
Tim Peters84ef21c2006-02-28 20:39:06 +00001952- PEP 343: with statement implemented. Needs ``from __future__ import
1953 with_statement``. Use of 'with' as a variable will generate a warning.
1954 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001955 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001956 The following objects have __context__ methods:
1957 - The built-in file type.
1958 - The thread.LockType type.
1959 - The following types defined by the threading module:
1960 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1961 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001962
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001963- Fix the encodings package codec search function to only search
1964 inside its own package. Fixes problem reported in patch #1433198.
1965
1966 Note: Codec packages should implement and register their own
1967 codec search function. PEP 100 has the details.
1968
Tim Peters9ea89d22006-06-04 03:26:02 +00001969- PEP 353: Using ``Py_ssize_t`` as the index type.
1970
1971- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1972 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1973 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1974 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1975 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001976
Neal Norwitzfc76d632006-01-10 06:03:13 +00001977- Patch #1400181, fix unicode string formatting to not use the locale.
1978 This is how string objects work. u'%f' could use , instead of .
1979 for the decimal point. Now both strings and unicode always use periods.
1980
Neal Norwitz671b9e32006-01-09 07:07:12 +00001981- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1982 configure would break checking curses.h.
1983
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001984- Bug #959576: The pwd module is now builtin. This allows Python to be
1985 built on UNIX platforms without $HOME set.
1986
Neal Norwitzc10978f2005-12-19 06:07:16 +00001987- Bug #1072182, fix some potential problems if characters are signed.
1988
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001989- Bug #889500, fix line number on SyntaxWarning for global declarations.
1990
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001991- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1992
Neal Norwitze7214a12005-12-18 05:03:17 +00001993- Support for converting hex strings to floats no longer works.
1994 This was not portable. float('0x3') now raises a ValueError.
1995
Barry Warsaw2a38a862005-12-18 01:27:35 +00001996- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001997 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001998 is now displayed in interactive prompt banner.
1999
Georg Brandlfa166682005-12-17 21:45:17 +00002000- Implementation of PEP 341 - Unification of try/except and try/finally.
2001 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002002 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002003
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002004- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2005 now encodes backslash correctly.
2006
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002007- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2008
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002009- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002010 and long longs.
2011
Neal Norwitz67715f02005-11-09 06:59:35 +00002012- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002013 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002014 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002015
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002016- Replaced most Unicode charmap codecs with new ones using the
2017 new Unicode translate string feature in the builtin charmap
2018 codec; the codecs were created from the mapping tables available
2019 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2020 encodings now include a mapping for the Apple logo)
2021
Tim Peterse3547fd2005-12-16 23:13:57 +00002022- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002023
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002024- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002025
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002026- A new AST parser implementation was completed. The abstract
2027 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002028 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002029
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002030- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002031 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2032
Neal Norwitz708e51a2005-10-03 04:48:15 +00002033- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2034
Neal Norwitz11bd1192005-10-03 00:54:56 +00002035- SF Bug #887946: fix segfault when redirecting stdin from a directory.

2039
2040- SF bug #772896: unknown encoding results in MemoryError.
2041
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002042- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002043 supported a __len__() method which evaluated to False when the iterator
2044 was empty.
2045
Guido van Rossum630db602005-09-20 18:49:54 +00002046- On 64-bit platforms, when __len__() returns a value that cannot be
2047 represented as a C int, raise OverflowError.

Skip Montanarof8948ca2005-09-19 03:54:46 +00002049- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002050 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002051
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002052- SF bug #893549: parsing keyword arguments was broken with a few format
2053 codes.
2054
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002055- Changes donated by Elemental Security to make it work on AIX 5.3
2056 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2057 bug #105470: test_pwd fails on 64bit system (Opteron).
2058
Guido van Rossum539c6622005-09-14 17:49:54 +00002059- Changes donated by Elemental Security to make it work on HP-UX 11 on
2060 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2061
Georg Brandl4550b8d2005-08-26 06:43:52 +00002062- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002063 (fixes bug #1119418).
2064
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002065- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2066
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002067- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2068 exceptions that cause a function to exit.
2069
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002070- The implementation of set() and frozenset() was revised to use its
2071 own internal data structure. Memory consumption is reduced by 1/3
2072 and there are modest speed-ups as well. The API is unchanged.
2073
Tim Petersde7990b2005-07-17 23:45:23 +00002074- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2075
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002076- SF bug #1229429: PyObject_CallMethod failed to decrement some
2077 reference counts in some error exit cases.
2078
Tim Petersecc6e6a2005-07-10 22:30:55 +00002079- SF bug #1185883: Python's small-object memory allocator took over
2080 a block managed by the platform C library whenever a realloc specified
2081 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002082 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002083 portable way to copy data from the C-managed block into Python's
2084 small-object space without risking a memory fault. Python's small-object
2085 realloc now leaves such blocks under the control of the platform C
2086 realloc.
2087
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002088- SF bug #1232517: An overflow error was not detected properly when
2089 attempting to convert a large float to an int in os.utime().
2090
Raymond Hettinger3296e692005-06-29 23:29:56 +00002091- SF bug #1224347: hex longs now print with lowercase letters just
2092 like their int counterparts.
2093
Michael W. Hudson188d4362005-06-20 16:52:57 +00002094- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2095 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2096 interpreter states; back out that fix and do a better job (see
2097 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2098 for a longer write-up of the problem).
2099
Michael W. Hudsondf888462005-06-03 14:41:55 +00002100- SF patch #1180995: marshal now uses a binary format by default when
2101 serializing floats.
2102
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002103- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2104 the routines that promise to produce IEEE 754 binary representations
2105 of floats now simply copy bytes around.
2106
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002107- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2108 278.
2109
Brett Cannonc3647ac2005-04-26 03:45:26 +00002110- patch #1109424: int, long, float, complex, and unicode now check for the
2111 proper magic slot for type conversions when subclassed. Previously the
2112 magic slot was ignored during conversion. Semantics now match the way
2113 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002114 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002115 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002116 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002117
Barry Warsawc8d907c2005-04-19 23:43:40 +00002118- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2119 NULL, now raise an AttributeError when attempting to set or delete the
2120 attribute. Previously a TypeError was raised, but this was inconsistent
2121 with the equivalent pure-Python implementation.
2122
Michael W. Hudson774479c2005-04-18 08:46:17 +00002123- It is now safe to call PyGILState_Release() before
2124 PyEval_InitThreads() (note that if there is reason to believe there
2125 are multiple threads around you still must call PyEval_InitThreads()
2126 before using the Python API; this fix is for extension modules that
2127 have no way of knowing if Python is multi-threaded yet).
2128
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002129- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2130 disabled caused a crash.
2131
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002132- Bug #1165306: instancemethod_new allowed the creation of a method
2133 with im_class == im_self == NULL, which caused a crash when called.
2134
Tim Petersecc6e6a2005-07-10 22:30:55 +00002135- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002136 fixes the crash seen in bug #1165761
2137
Raymond Hettinger96229b12005-03-11 06:49:40 +00002138- Added two new builtins, any() and all().
2139
Brett Cannon409d8f22005-03-05 06:47:57 +00002140- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002141 (e.g., ``class C(): pass`` is no longer a syntax error).
2142 Patch #1176012 added support to the 'parser' module and 'compiler' package
2143 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002144
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002145- Patch #1115086: Support PY_LONGLONG in structmember.
2146
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002147- Bug #1155938: new style classes did not check that __init__() was
2148 returning None.
2149
Tim Petersecc6e6a2005-07-10 22:30:55 +00002150- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002151 ('\') with a specific error message.
2152
Martin v. Löwisff232d72005-03-03 09:24:38 +00002153- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2154
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002155- Bug #1124295: the __name__ attribute of file objects was
2156 inadvertently made inaccessible in restricted mode.
2157
Tim Petersecc6e6a2005-07-10 22:30:55 +00002158- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002159 an ferror() call.
2160
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002161- min() and max() now support key= arguments with the same meaning as in
2162 list.sort().
2163
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002164- The peephole optimizer now performs simple constant folding in expressions:
2165 (2+3) --> (5).
2166
Raymond Hettingera422c342005-01-11 03:03:27 +00002167- set and frozenset objects can now be marshalled. SF #1098985.
2168
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002169- Bug #1077106: Poor argument checking could cause memory corruption
2170 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002171
Jeremy Hyltonab630502005-02-04 18:44:06 +00002172- The parser did not complain about future statements in illegal
2173 positions. It once again reports a syntax error if a future
2174 statement occurs after anything other than a doc string.
2175
Neil Schemenauercf52c072005-08-12 17:34:58 +00002176- Change the %s format specifier for str objects so that it returns a
2177 unicode instance if the argument is not an instance of basestring and
2178 calling __str__ on the argument returns a unicode instance.
2179
Tim Petersf4e69282006-02-27 17:15:31 +00002180- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2181 current thread state when the auto-GIL-state machinery knows about
2182 it (since the thread state is being deleted, continuing to remember it
2183 can't help, but can hurt if another thread happens to get created with
2184 the same thread id).
2185
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002186Extension Modules
2187-----------------
2188

Neal Norwitz10be10c2006-03-16 06:50:13 +00002202 util, whatsound, whrandom, zmod
2203
2204- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2205
2206- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002207 is deprecated. The undocumented re.engine variable no longer exists.
2208

2210 SS2 (single-shift 2) escape sequences correctly.
2211
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002212- The unicodedata module was updated to the 4.1 version of the Unicode
2213 database. The 3.2 version is still available as unicodedata.db_3_2_0
2214 for applications that require this specific version (such as IDNA).
2215
Neal Norwitzb62c4332006-03-04 18:35:47 +00002216- The timing module is no longer built by default. It was deprecated
2217 in PEP 4 in Python 2.0 or earlier.
2218
Guido van Rossum1968ad32006-02-25 22:38:04 +00002219- Patch 1433928: Added a new type, defaultdict, to the collections module.
2220 This uses the new __missing__ hook behavior added to dict (see above).
2221
Georg Brandldbd83392006-02-20 09:42:33 +00002222- Bug #854823: socketmodule now builds on Sun platforms even when
2223 INET_ADDRSTRLEN is not defined.
2224
Georg Brandlf4f44152006-02-18 22:29:33 +00002225- Patch #1393157: os.startfile() now has an optional argument to specify
2226 a "command verb" to invoke on the file.
2227
Neal Norwitz082b2df2006-02-07 07:04:46 +00002228- Bug #876637, prevent stack corruption when socket descriptor

2230
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00002231- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
2232 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
2233 mmap.mmap(0, size) should not be used on Windows for anonymous memory.

2236 than the system default domain.
2237
Martin v. Löwis14694662006-02-03 12:54:16 +00002238- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2239 are reported, the limit on path name lengths is removed, and stat reports
2240 WindowsError now (instead of OSError).
2241
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002242- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

2317 the request code argument, which results in more C-like behaviour
2318 for large or negative values.
2319
Tim Petersecc6e6a2005-07-10 22:30:55 +00002320- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

2329 available on the platform.
2330
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002331- Bug #1166660: The readline module could segfault if hook functions
2332 were set in a different thread than that which called readline.
2333

2335
Raymond Hettinger984f9bb2005-03-09 16:38:48 +00002336- operator.itemgetter() and operator.attrgetter() now support retrieving

2362
Raymond Hettingerb2594052004-12-05 09:25:51 +00002363- itertools.islice() now accepts None for the start and step arguments.
2364 This allows islice() to work more readily with slices:
2365 islice(s.start, s.stop, s.step)
2366
Skip Montanaro0af3ade2005-01-13 04:12:31 +00002367- datetime.datetime() now has a strptime class method which can be used to

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002376- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2377 been renamed to have only a single underscore prefix. This was done to
2378 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002379
Nick Coghlan43832302006-04-23 17:04:07 +00002380- PEP 338: new module runpy defines a run_module function to support
2381 executing modules which provide access to source code or a code object
2382 via the PEP 302 import mechanisms.
2383
Anthony Baxter93f5b932006-04-03 08:05:07 +00002384- The email module's parsedate_tz function now sets the daylight savings

2392 in attribute values.
2393
Anthony Baxterc51ee692006-04-01 00:57:31 +00002394- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002395 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002396 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002397 module will not be built.
2398
Tim Petersc17976e2006-04-01 00:26:53 +00002399- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2400 aren't officially supported here, and trying to use them will probably
2401 raise an exception some day. But dicts have been allowed, and "mostly
2402 worked", so support for them won't go away without warning.
2403
Georg Brandl338ef7d2006-03-31 18:42:16 +00002404- Bug #1445068: getpass.getpass() can now be given an explicit stream
2405 argument to specify where to write the prompt.
2406
Georg Brandl22ec80b2006-03-31 18:25:44 +00002407- Patch #1462313, bug #1443328: the pickle modules now can handle classes
2408 that have __private names in their __slots__.

2414
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002415- Queue.Queue objects now support .task_done() and .join() methods
2416 to make it easier to monitor when daemon threads have completed
2417 processing all enqueued tasks. Patch #1455676.
2418
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002419- popen2.Popen objects now preserve the command in a .cmd attribute.

2422
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002423- email 4.0 package now integrated. This is largely the same as the email 3.0
2424 package that was included in Python 2.3, except that PEP 8 module names are
2425 now used (e.g. mail.message instead of email.Message). The MIME classes
2426 have been moved to a subpackage (e.g. email.mime.text instead of
2427 email.MIMEText). The old names are still supported for now. Several
2428 deprecated Message methods have been removed and lots of bugs have been
2429 fixed. More details can be found in the email package documentation.
2430
Walter Dörwald40108c92006-03-27 08:15:44 +00002431- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2432 (a subclass of tuple) that provides incremental decoders and encoders
2433 (a way to use stateful codecs without the stream API). Python functions
2434 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2435 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2436 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002437
Walter Dörwald067db482006-03-15 22:17:27 +00002438- Patch #1359365: Calling next() on a closed StringIO.String object raises
2439 a ValueError instead of a StopIteration now (like file and cString.String do).
2440 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2441 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002442
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002443- A regrtest option -w was added to re-run failed tests in verbose mode.

2455 and helpful context managers nested() and closing().
2456

Tim Peterse3547fd2005-12-16 23:13:57 +00002515 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2516 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2517 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2518 Ronald L. Rivest offered this advice for Python:
2519
2520 "The consensus of researchers in this area (at least as
2521 expressed at the NIST Hash Function Workshop 10/31/05),
2522 is that SHA-256 is a good choice for the time being, but
2523 that research should continue, and other alternatives may
2524 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002525
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002526- Added a subset of Fredrik Lundh's ElementTree package. Available

2579 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002580 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002581

Guido van Rossum755149f2005-07-27 00:00:44 +00002589- Fix a problem in Tkinter introduced by SF patch #869468: delete bogus
2590 __hasattr__ and __delattr__ methods on class Tk that were breaking
2591 Tkdnd.
2592
Georg Brandl5dbda752005-07-17 20:27:41 +00002593- Bug #1015140: disambiguated the term "article id" in nntplib docs and
2594 docstrings to either "article number" or "message id".
2595
Georg Brandla4a8b822005-07-15 09:13:21 +00002596- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
2597 parameter, but uses the usual "kwargs=None".
2598
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002599- textwrap now processes text chunks at O(n) speed instead of O(n**2).
Raymond Hettinger8bfa8932005-07-15 06:53:35 +00002600 Patch #1209527 (Contributed by Connelly).
2601
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00002602- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
2603 to W3C name (404 -> 'Not Found'). RFE #1216944.
2604
Georg Brandl9e43acf2005-07-04 17:16:07 +00002605- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2606 as this can cause problems with apps closing all file descriptors.
2607
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002608- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002609 it can be missing in embedded interpreters
Georg Brandl5284b532005-06-26 22:54:58 +00002610
Georg Brandl2f210b62005-06-26 22:09:06 +00002611- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
2612
Georg Brandlfbff1bc2005-06-26 21:36:25 +00002613- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
2614 error messages.
2615
Georg Brandl379f99d2005-06-26 21:09:38 +00002616- Bug #1108948: Cookie.py produced invalid JavaScript code.
2617
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00002618- The tokenize module now detects and reports indentation errors.
2619 Bug #1224621.
2620
Raymond Hettinger68c04532005-06-10 11:05:19 +00002621- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002622 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002623 the generate_tokens() function now accepts a callable argument that
2624 terminates by raising StopIteration.
2625
Georg Brandl9166e1a2005-06-04 09:20:03 +00002626- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2627
Georg Brandl268e61c2005-06-03 14:28:50 +00002628- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2629 component of the path.
2630
Skip Montanaro174dd222005-05-14 20:54:16 +00002631- Patch #1120353: The xmlrpclib module provides better, more transparent,
2632 support for datetime.{datetime,date,time} objects. With use_datetime set
2633 to True, applications shouldn't have to fiddle with the DateTime wrapper
2634 class at all.
2635
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002636- distutils.commands.upload was added to support uploading distribution
2637 files to PyPI.
2638
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002639- distutils.commands.register now encodes the data as UTF-8 before posting
2640 them to PyPI.
2641
Raymond Hettinger267b8682005-03-27 10:47:39 +00002642- decimal operator and comparison methods now return NotImplemented
2643 instead of raising a TypeError when interacting with other types. This
2644 allows other classes to implement __radd__ style methods and have them
2645 work as expected.
2646
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002647- Bug #1163325: Decimal infinities failed to hash. Attempting to
2648 hash a NaN raised an InvalidOperation instead of a TypeError.
2649
Tim Petersecc6e6a2005-07-10 22:30:55 +00002650- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002651 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2652

2682
Raymond Hettingerbab41432005-02-05 01:31:19 +00002683- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2684
Guido van Rossumd0641422005-02-03 15:01:24 +00002685- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2686 disables recursive traversal through instance attributes, which can
2687 be exploited in various ways.
2688
Tim Peterse3547fd2005-12-16 23:13:57 +00002689- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002690 flags on the HTTP listening socket.
2691
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002692- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2693 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2694
Fred Drakefbdeaad2006-07-29 16:56:15 +00002695- Patches #893642, #1039083: add allow_none, encoding arguments to
2696 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002697
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002698- Bug #1110478: Revert os.environ.update to do putenv again.
2699
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002700- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2701
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002702- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2703
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002704- Enhancements to the csv module:
2705
2706 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002707 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002708 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002709 + Dialect parameter parsing has been re-implemented to improve error
2710 reporting.
2711 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2712 dictates.
2713 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002714 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002715 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002716 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2717 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002718 + reader now allows \r characters to be quoted (previously it only allowed
2719 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002720 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002721 + Dialect classes passed to the module are no longer instantiated by
2722 the module before being parsed (the former validation scheme required
2723 this, but the mechanism was unreliable).
2724 + The dialect registry now contains instances of the internal
2725 C-coded dialect type, rather than references to python objects.
2726 + the internal c-coded dialect type is now immutable.
2727 + register_dialect now accepts the same keyword dialect specifications
2728 as the reader and writer, allowing the user to register dialects
2729 without first creating a dialect class.
2730 + a configurable limit to the size of parsed fields has been added -
2731 previously, an unmatched quote character could result in the entire
2732 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002733 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002734 the parser field size limit (returning the former limit). The initial
2735 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002736 + A line_num attribute has been added to the reader object, which tracks
2737 the number of lines read from the source iterator. This is not
2738 the same as the number of records returned, as records can span
2739 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002740 + reader and writer objects were not being registered with the cyclic-GC.
2741 This has been fixed.
2742
Brett Cannone6539c42005-01-08 02:43:53 +00002743- _DummyThread objects in the threading module now delete self.__block that is
2744 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2745 lock primitives tend to be limited in number and thus should not be wasted on
2746 a _DummyThread object. Fixes bug #1089632.
2747
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002748- The imghdr module now detects Exif files.
2749
Raymond Hettinger6065d322004-12-20 23:51:53 +00002750- StringIO.truncate() now correctly adjusts the size attribute.
2751 (Bug #951915).
2752
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002753- locale.py now uses an updated locale alias table (built using
2754 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2755 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002756 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002757
Raymond Hettinger3557f422004-12-07 12:02:02 +00002758- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2759
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002760- the pickle module no longer accepts the deprecated None option in the
2761 args tuple returned by __reduce__().
2762
Brett Cannon84667c02004-12-07 03:25:18 +00002763- optparse now optionally imports gettext. This allows its use in setup.py.
2764
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002765- the pickle module no longer uses the deprecated bin parameter.
2766
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002767- the shelve module no longer uses the deprecated binary parameter.
2768
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002769- the pstats module no longer uses the deprecated ignore() method.
2770
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002771- the filecmp module no longer uses the deprecated use_statcache argument.
2772
Raymond Hettinger664347b2004-12-04 21:21:53 +00002773- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2774 extended or overridden by subclasses. Formerly, the subclassed method would
2775 be ignored by the rest of the module. (Bug #1078905).
2776
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002777- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002778 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002779
Walter Dörwald36733692004-12-22 12:50:50 +00002780- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2781 once when a size argument is given. This prevents a buffer overflow in the
2782 tokenizer with very long source lines.
2783
Barry Warsaw538561e2006-01-01 21:48:54 +00002784- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2785 immediately after creating the object, without any intervening
2786 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002787
Skip Montanaro05885812005-01-16 20:48:27 +00002788- The reconvert.quote function can now emit triple-quoted strings. The
2789 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002790
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002791- ``UserString.MutableString`` now supports negative indices in
2792 ``__setitem__`` and ``__delitem__``
2793
Greg Ward40407942005-03-05 02:53:17 +00002794- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2795 correctly.
2796
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002797- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2798 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2799 character even if the user has passed a size parameter to get a proper
2800 line ending. Remove the special handling of a "\r\n" that has been split
2801 between two lines.
2802
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002803- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2804 about illegal code points. The codec now supports PEP 293 style error
2805 handlers.
2806
Walter Dörwald78a78b02005-09-01 12:04:29 +00002807- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002808 from the input stream, so that the output is a byte string in the correct
2809 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002810
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002811- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2812 considering it exactly like a '*'.
2813
Walter Dörwald007f8df2005-10-09 19:42:27 +00002814- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2815 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002816
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002817- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2818
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002819- Patch #1413711: Certain patterns of differences were making difflib
2820 touch the recursion limit.
2821
Walter Dörwald58917a62006-03-31 15:26:22 +00002822- Bug #947906: An object oriented interface has been added to the calendar
2823 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002824 called as a script (e.g. via ``python -mcalendar``). Localized month and
2825 weekday names can be ouput (even if an exotic encoding is used) using
2826 special classes that use unicode.

Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002838- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2839
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002840- Patch #881820: look for openpty and forkpty also in libbsd.
2841
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002842- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2843 The zlib module is now builtin on Windows.
2844
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002845- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2846
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002847- Bug #1189330: configure did not correctly determine the necessary
2848 value of LINKCC if python was built with GCC 4.0.
2849
Trent Mick8321b422005-07-26 02:29:21 +00002850- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2851 vulnerability in zlib 1.2.1 and 1.2.2.
2852
Brett Cannon08cd5982005-04-24 22:26:38 +00002853- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2854 flags that change binary compatibility. Changes were also made to
2855 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002856 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002857
Bob Ippolitoed233462005-03-29 13:47:59 +00002858- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2859 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2860 no longer exists). This configure patch makes things right.
2861
Martin v. Löwise2713be2005-03-08 15:03:08 +00002862- Bug #1158607: Build with --disable-unicode again.
2863
Brett Cannon46d96232005-02-16 00:07:19 +00002864- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2865 defined. Discovered as a result of not being able to build on OS X.
2866
Brett Cannon516592f2004-12-07 00:42:59 +00002867- setup.py now uses the directories specified in LDFLAGS using the -L option
2868 and in CPPFLAGS using the -I option for adding library and include
2869 directories, respectively, for compiling extension modules against. This has
2870 led to the core being compiled using the values in CPPFLAGS. It also removes
2871 the need for the special-casing of both DarwinPorts and Fink for darwin since
2872 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2873 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2874 Fink, ``-I/opt/local/include`` for DarwinPorts).
2875
Brett Cannon43802422005-02-10 20:48:03 +00002876- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2877 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2878 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2879 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002881C API
2882-----
2883
Tim Petersc9d78aa2006-03-26 23:27:58 +00002884- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2885 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2886 is obtained via the ``PyObject_`` family, it must be released via the
2887 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2888 always been officially true, but when Python's small-object allocator was
2889 introduced, an attempt was made to cater to a few extension modules
2890 discovered at the time that obtained memory via ``PyObject_New`` but
2891 released it via ``PyMem_DEL``. It's years later, and if such code still
2892 exists it will fail now (probably with segfaults, but calling wrong
2893 low-level memory management functions can yield many symptoms).
2894
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002895- Added a C API for set and frozenset objects.
2896
Raymond Hettinger66517482004-12-03 11:45:13 +00002897- Removed PyRange_New().
2898
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002899- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2900 mapping argument now. This string is used as a mapping table. Byte values
2901 greater than the length of the string and 0xFFFE are treated as undefined
2902 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00002908- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002909
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002910- Patch #1276356: New resource "urlfetch" is implemented. This enables
2911 even impatient people to run tests that require remote files.
