676
Neal Norwitz0bcafac2006-09-11 08:51:17 +0000677- Make _PyGILState_NoteThreadState() static, it was not used anywhere
678 outside of pystate.c and should not be necessary.
679
Brett Cannon19d76c52006-09-09 07:18:44 +0000680- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
681 allows calling unicode() on exceptions classes directly to succeed.
682
Georg Brandlecab6232006-09-06 06:47:02 +0000683- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

699 head is the original string if sep was not found.
700
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000701- Bug #1520864: unpacking singleton tuples in list comprehensions and
702 generator expressions (x for x, in ... ) works again. Fixing this problem
703 required changing the .pyc magic number. This means that .pyc files
704 generated before 2.5c2 will be regenerated.

817-----------------
818
Neal Norwitz24b6f202006-09-05 04:43:56 +0000819- Fix infinite recursion when subclassing long and overriding __hash__.
820
821- Fix concatenation (+=) of long strings.
822
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000823- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000824 compared equal or unequal to a string and a UnicodeDecodeError
825 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000826
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000827 Instead, the equal (==) and unequal (!=) comparison operators will
828 now issue a UnicodeWarning and interpret the two objects as
829 unequal. The UnicodeWarning can be filtered as desired using
830 the warning framework, e.g. silenced completely, turned into an
831 exception, logged, etc.
832
833 Note that compare operators other than equal and unequal will still
834 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000835
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000836- Fix segfault when doing string formatting on subclasses of long.
837
838- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
839 with new-style classes.
840
841- Fix bug related to __len__ functions returning negative values with
842 classic classes.
843
844- Patch #1538606, Fix __index__() clipping. There were some problems
845 discovered with the API and how integers that didn't fit into Py_ssize_t
846 were handled. This patch attempts to provide enough alternatives
847 to effectively use __index__.
848
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000849- Bug #1536021: __hash__ may now return long int; the final hash
850 value is obtained by invoking hash on the long int.
851
Thomas Hellerab1049c2006-08-08 17:37:00 +0000852- Bug #1536786: buffer comparison could emit a RuntimeWarning.
853
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000854- Bug #1535165: fixed a segfault in input() and raw_input() when
855 sys.stdin is closed.
856
Thomas Heller74d36f02006-08-04 18:17:40 +0000857- On Windows, the PyErr_Warn function is now exported from
858 the Python dll again.
859
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000860- Bug #1191458: tracing over for loops now produces a line event
861 on each iteration. Fixing this problem required changing the .pyc
862 magic number. This means that .pyc files generated before 2.5c1
863 will be regenerated.
864
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000865- Bug #1333982: string/number constants were inappropriately stored
866 in the byte code and co_consts even if they were not used, ie
867 immediately popped off the stack.
868
Georg Brandle9462c72006-08-04 18:03:37 +0000869- Fixed a reference-counting problem in property().

873-------
874
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000875- Fix a bug in the ``compiler`` package that caused invalid code to be
876 generated for generator expressions.
877
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000878- The distutils version has been changed to 2.5.0. The change to
879 keep it programmatically in sync with the Python version running
880 the code (introduced in 2.5b3) has been reverted. It will continue
881 to be maintained manually as static string literal.
882
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000883- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000884 and this cannot be converted to the required C type, an exception is
885 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000886 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000887
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000888- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000889 an exception.
890
Tim Peterscbdd3502006-09-05 01:47:53 +0000891- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000892 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000893 workarounds for clocks with low resolution, to stop the code yielding
894 duplicate UUIDs.

Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000896- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
897 before raising SystemExit, allowing IDLE to honor quit() and exit().
898

Georg Brandl7a1af772006-08-14 21:55:28 +0000901- Patch #1536071: trace.py should now find the full module name of a
902 file correctly even on Windows.
903
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000904- logging's atexit hook now runs even if the rest of the module has
905 already been cleaned up.
906

910 str(exception) raised an exception.
911
Neil Schemenauer06ded092006-08-04 16:20:30 +0000912- Fix a bug in the ``compiler`` package that caused invalid code to be
913 generated for nested functions.

924 raises the correct exceptions.
925
Thomas Heller1ce433e2006-08-14 16:20:04 +0000926- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
927 '-no-stack-protector' compiler flag for OpenBSD has been removed.
928
Thomas Heller86720042006-08-14 11:17:48 +0000929- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
930 uses the _as_parameter_ attribute when objects are passed to foreign
931 function calls. The ctypes version number was changed to 1.0.1.
932
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000933- Bug #1530559, struct.pack raises TypeError where it used to convert.
934 Passing float arguments to struct.pack when integers are expected
935 now triggers a DeprecationWarning.

Martin v. Löwisa09fd6e2006-08-16 12:55:10 +0000961- Bug #1535502, build _hashlib on Windows, and use masm assembler
962 code in OpenSSL.
963
Thomas Hellerdb7b4432006-08-04 19:49:31 +0000964- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

970-----
971
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000972- New API for Unicode rich comparisons: PyUnicode_RichCompare()
973
Tim Peters4643c2f2006-08-10 22:45:34 +0000974- Bug #1069160. Internal correctness changes were made to
975 ``PyThreadState_SetAsyncExc()``. A test case was added, and
976 the documentation was changed to state that the return value
977 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +0000980What's New in Python 2.5 beta 3?
981================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000982
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000983*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000984
985Core and builtins
986-----------------
987
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000988- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000989 returned a long (see PEP 353).
990
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000991- Bug #1515471: string.replace() accepts character buffers again.
992
Neal Norwitz07aadb12006-07-30 06:55:48 +0000993- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
994 This provides the proper warning for struct.pack().
995 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
996
Neal Norwitz0d62a062006-07-30 06:53:31 +0000997- Patch #1531113: Fix augmented assignment with yield expressions.
998 Also fix a SystemError when trying to assign to yield expressions.
999
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001000- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1001 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1002 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1003 excessive filesystem operations during imports.
1004
Tim Petersbc24eee2006-07-27 01:14:53 +00001005- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1006 operations on signed longs that are formally undefined by C.
1007 Unfortunately, at least one compiler now cares about that, so complicated
1008 the code to make that compiler happy again.
1009
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001010- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1011
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001012- Patch #1232023: Stop including current directory in search
1013 path on Windows.
1014
Neal Norwitze1fdb322006-07-21 05:32:28 +00001015- Fix some potential crashes found with failmalloc.
1016
Neal Norwitze7563102006-07-17 01:00:16 +00001017- Fix warnings reported by Klocwork's static analysis tool.
1018
Neal Norwitz84be93b2006-07-16 01:50:38 +00001019- Bug #1512814, Fix incorrect lineno's when code within a function
1020 had more than 255 blank lines.
1021
Georg Brandl9dceedb2006-07-12 15:31:17 +00001022- Patch #1521179: Python now accepts the standard options ``--help`` and
1023 ``--version`` as well as ``/?`` on Windows.
1024
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001025- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001026 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001027 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001028
Tim Peters112aad32006-07-19 00:03:19 +00001029- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001030 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001031 new ``sys._current_frames()`` returns a dictionary with one entry,
1032 mapping the faux "thread id" 0 to the current frame.
1033
Ronald Oussoren3075e162006-07-25 20:28:55 +00001034- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001035

Neal Norwitza1f10902006-07-12 07:28:29 +00001037Library
1038-------
1039
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001040- Correction of patch #1455898: In the mbcs decoder, set final=False
1041 for stream decoder, but final=True for the decode function.
1042
Georg Brandl07fec3a2006-08-01 18:49:24 +00001043- os.urandom no longer masks unrelated exceptions like SystemExit or
1044 KeyboardInterrupt.
1045
Tim Peters4643c2f2006-08-10 22:45:34 +00001046- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001047 shutil.copytree on Windows
1048
Georg Brandle34ac7c2006-07-30 11:07:23 +00001049- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1050 refers to file descriptors, not file objects.
1051
Tim Peterscbdd3502006-09-05 01:47:53 +00001052- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001053 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001054 #1513611, and probably others.
1055
Georg Brandledd9b0d2006-07-29 09:33:26 +00001056- Bug #1441397: The compiler module now recognizes module and function
1057 docstrings correctly as it did in Python 2.4.
1058
Tim Peters6f681472006-07-27 23:44:37 +00001059- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1060 lost that tests are sorted by name before being run. This rarely
1061 matters for well-written tests, but can create baffling symptoms if
1062 side effects from one test to the next affect outcomes. ``DocTestFinder``
1063 has been changed to sort the list of tests it returns.
1064
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001065- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001066 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001067
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001068- Bug #978833: Really close underlying socket in _socketobject.close.
1069
Georg Brandldb232dc2006-08-20 13:15:43 +00001070- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1071 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001072
Georg Brandlcf0c1722006-07-26 07:23:32 +00001073- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1074 to recursive calls and call it with the failing package name.
1075
Martin v. Löwis0b483032006-07-25 09:53:12 +00001076- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1077
Georg Brandlc13c34c2006-07-24 14:09:56 +00001078- Patch #1515343: Fix printing of deprecated string exceptions with a
1079 value in the traceback module.
1080
Greg Ward48fae7a2006-07-23 16:05:51 +00001081- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1082
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001083- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1084
Brett Cannoncaebe222006-07-18 04:41:36 +00001085- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1086 argument tuple. For arguments where zero is illegal, the value is forced to
1087 the minimum value that is correct. This is to support an undocumented but
1088 common way people used to fill in inconsequential information in the time
1089 tuple pre-2.4.
1090
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001091- Patch #1220874: Update the binhex module for Mach-O.
1092
Barry Warsawb110bad2006-07-21 14:51:07 +00001093- The email package has improved RFC 2231 support, specifically for
1094 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1095 (name*0=<blah>) parameter continuations. This may change the types of
1096 values returned from email.message.Message.get_param() and friends.
1097 Specifically in some cases where non-encoded continuations were used,
1098 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1099 will just return the string (since non-encoded continuations don't have
1100 charset and language parts).
1101
1102 Also, whereas % values were decoded in all parameter continuations, they are
1103 now only decoded in encoded parameter parts.
1104
Ronald Oussoren3075e162006-07-25 20:28:55 +00001105- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1106
1107- Bug #1517996: IDLE now longer shows the default Tk menu when a
1108 path browser, class browser or debugger is the frontmost window on MacOS X
1109
Barry Warsaw00decd72006-07-27 23:43:15 +00001110- Patch #1520294: Support for getset and member descriptors in types.py,
1111 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1112 of an object against these built-in types and more importantly, for getting
1113 their docstrings printed in the interactive interpreter's help() function.

1118
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001119- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1120 a socket operation on a socket with a timeout, the exception will be
1121 caught correctly. Previously, the exception was not caught.
1122
Thomas Heller1393d6a2006-07-28 21:43:20 +00001123- Patch #1529514: The _ctypes extension is now compiled on more
1124 openbsd target platforms.
1125
Tim Peters9cab5932006-07-28 00:30:00 +00001126- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1127 a memory leak, affecting pickles and deep copies.
1128
Tim Petersbc24eee2006-07-27 01:14:53 +00001129- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1131
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001132- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1133
Thomas Hellerce049a02006-07-14 17:51:14 +00001134- Patch #1521817: Index range checking on ctypes arrays containing
1135 exactly one element enabled again. This allows iterating over these
1136 arrays, without the need to check the array size before.
1137
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001138- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001139 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001140 /dev/null in certain cases; this is now fixed.
1141
Thomas Heller47d7a062006-07-12 08:43:47 +00001142- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1143 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001144
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001145- Because of a misspelled preprocessor symbol, ctypes was always
1146 compiled without thread support; this is now fixed.
1147
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001148- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1149 methods now allow their database parameter to be None as the
1150 sleepycat API allows.
1151
Matt Flemingec926502006-07-28 11:27:27 +00001152- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1153 bluetooth API compared with Linux and FreeBSD.
1154

1156-----
1157
1158- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1159 how long the test file should take to play. Now accepts taking 2.93 secs
1160 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1161
Georg Brandl4793aa32006-07-28 18:31:39 +00001162- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1163 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1164 run via ``regrtest.py``. Now they do.

1174- PythonLauncher now works correctly when the path to the script contains
1175 characters that are treated specially by the shell (such as quotes).
1176
1177- Bug #1527397: PythonLauncher now launches scripts with the working directory
1178 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001179 directory. That latter was an implementation accident and not what users

1188Core and builtins
1189-----------------
1190
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001191- Bug #1441486: The literal representation of -(sys.maxint - 1)
1192 again evaluates to a int object, not a long.
1193
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001194- Bug #1501934: The scope of global variables that are locally assigned
1195 using augmented assignment is now correctly determined.
1196
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001197- Bug #927248: Recursive method-wrapper objects can now safely
1198 be released.
1199
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001200- Bug #1417699: Reject locale-specific decimal point in float()
1201 and atof().
1202
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001203- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1204 omit a default "error" argument for NULL pointer. This allows
1205 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001206
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001207- Bug #1519018: 'as' is now validated properly in import statements.
1208
Neal Norwitz28746ab2006-07-09 22:14:42 +00001209- On 64 bit systems, int literals that use less than 64 bits are
1210 now ints rather than longs.
1211
Neal Norwitzed657552006-07-10 00:04:44 +00001212- Bug #1512814, Fix incorrect lineno's when code at module scope
1213 started after line 256.
1214
Tim Peters32a83612006-07-10 21:08:24 +00001215- New function ``sys._current_frames()`` returns a dict mapping thread
1216 id to topmost thread stack frame. This is for expert use, and is
1217 especially useful for debugging application deadlocks. The functionality
1218 was previously available in Fazal Majid's ``threadframe`` extension
1219 module, but it wasn't possible to do this in a wholly threadsafe way from
1220 an extension.
1221

1223-------
1224
Martin v. Löwis77621582006-07-30 13:27:31 +00001225- Bug #1257728: Mention Cygwin in distutils error message about a missing
1226 VS 2003.
1227
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001228- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1229
Tim Peters32a83612006-07-10 21:08:24 +00001230- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001231 environment variable to be set in order to the SDK environment
1232 for finding the compiler, include files, etc.
1233
Martin v. Löwis388a8c22006-07-06 19:28:03 +00001234- Bug #1515998: Properly generate logical ids for files in bdist_msi.
1235
Nick Coghlan2d792252006-07-06 13:47:18 +00001236- warnings.py now ignores ImportWarning by default
1237
Thomas Woutersadd19112006-07-05 11:03:49 +00001238- string.Template() now correctly handles tuple-values. Previously,
1239 multi-value tuples would raise an exception and single-value tuples would
1240 be treated as the value they contain, instead.
1241
Martin v. Löwisede77f52006-07-03 13:01:35 +00001242- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1243 even if some data are received.

Martin v. Löwis45482392006-07-03 12:28:58 +00001245- Bug #1267547: Put proper recursive setup.py call into the
1246 spec file generated by bdist_rpm.

Martin v. Löwis2b88f632006-07-03 10:19:49 +00001248- Bug #1514693: Update turtle's heading when switching between
1249 degrees and radians.
1250
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001251- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001252 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001253
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001254- Bug #1514703: Only setup canvas window in turtle when the canvas
1255 is created.

1261 attribute values.
1262
1263- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1264 sgmllib ('[' and ']' were not accepted).
1265
Georg Brandl1be63af2006-06-28 20:23:25 +00001266- Fix a bug in the turtle module's end_fill function.
1267
Brett Cannon53ab5b72006-06-22 16:49:14 +00001268- Bug #1510580: The 'warnings' module improperly required that a Warning
1269 category be either a types.ClassType and a subclass of Warning. The proper
1270 check is just that it is a subclass with Warning as the documentation states.
1271
Georg Brandlad29e632006-06-21 17:45:17 +00001272- The compiler module now correctly compiles the new try-except-finally
1273 statement (bug #1509132).
1274
Neal Norwitz60373cd2006-06-22 06:30:50 +00001275- The wsgiref package is now installed properly on Unix.
1276
Vinay Sajip28e57612006-07-01 10:45:20 +00001277- A bug was fixed in logging.config.fileConfig() which caused a crash on
1278 shutdown when fileConfig() was called multiple times.
1279
Gerhard Häring762fbd32006-07-02 17:48:30 +00001280- The sqlite3 module did cut off data from the SQLite database at the first
1281 null character before sending it to a custom converter. This has been fixed
1282 now.
1283
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001284Extension Modules
1285-----------------
1286
Tim Peters112aad32006-07-19 00:03:19 +00001287- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1288 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1289 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001290
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001291- Assigning None to pointer type fields in ctypes structures possible
1292 overwrote the wrong fields, this is fixed now.
1293
1294- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1295 on non-Windows platforms.
1296
1297- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1298 integer or long, without range checking.
1299
1300- Patch #1517790: It is now possible to use custom objects in the ctypes
1301 foreign function argtypes sequence as long as they provide a from_param
1302 method, no longer is it required that the object is a ctypes type.
1303
1304- The '_ctypes' extension module now works when Python is configured
1305 with the --without-threads option.
1306
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001307- Bug #1513646: os.access on Windows now correctly determines write
1308 access, again.
1309
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001310- Bug #1512695: cPickle.loads could crash if it was interrupted with
1311 a KeyboardInterrupt.
1312
Neal Norwitza12aa882006-07-06 06:45:08 +00001313- Bug #1296433: parsing XML with a non-default encoding and
1314 a CharacterDataHandler could crash the interpreter in pyexpat.
1315
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001316- Patch #1516912: improve Modules support for OpenVMS.
1317
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001318Build
1319-----
1320
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001321- Automate Windows build process for the Win64 SSL module.
1322
Tim Peters32a83612006-07-10 21:08:24 +00001323- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001324 Previously, the slight difference could cause compilation errors of the
1325 'zlib' module on systems with more than one version of zlib.
1326
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001327- The MSI compileall step was fixed to also support a TARGETDIR
1328 with spaces in it.
1329
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001330- Bug #1517388: sqlite3.dll is now installed on Windows independent
1331 of Tcl/Tk.
1332
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001333- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001334 trying to be installed even though it's empty.
Georg Brandlad29e632006-06-21 17:45:17 +00001335
Neal Norwitzb15ac312006-06-29 04:10:08 +00001336Tests
1337-----
1338
1339- Call os.waitpid() at the end of tests that spawn child processes in order
1340 to minimize resources (zombies).
1341
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001342Documentation
1343-------------
1344
Nick Coghlan2d792252006-07-06 13:47:18 +00001345- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1346 documentation for the warnings module.
1347
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001348- Patch #1509163: MS Toolkit Compiler no longer available.
1349
Neal Norwitz56640df2006-07-10 02:36:41 +00001350- Patch #1504046: Add documentation for xml.etree.

Nick Coghlanc649ec52006-05-29 12:43:05 +00001353What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +00001354================================
Anthony Baxter51bcb682006-04-05 14:51:42 +00001355
Anthony Baxterd1136802006-06-19 12:04:15 +00001356*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +00001357
1358Core and builtins
1359-----------------
1360
Georg Brandla56b9152006-06-19 06:35:54 +00001361- Patch #1507676: Error messages returned by invalid abstract object operations
1362 (such as iterating over an integer) have been improved and now include the
1363 type of the offending object to help with debugging.
1364
Brett Cannonea3912b2006-06-13 21:46:41 +00001365- Bug #992017: A classic class that defined a __coerce__() method that returned
1366 its arguments swapped would infinitely recurse and segfault the interpreter.
1367
Neal Norwitz909eb122006-06-12 02:13:21 +00001368- Fix the socket tests so they can be run concurrently.
1369
Neal Norwitzb9845e72006-06-12 02:11:18 +00001370- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001371 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001372
Brett Cannon22565aa2006-06-09 22:31:23 +00001373- Bug #532646: object.__call__() will continue looking for the __call__
1374 attribute on objects until one without one is found. This leads to recursion
1375 when you take a class and set its __call__ attribute to an instance of the
1376 class. Originally fixed for classic classes, but this fix is for new-style.
1377 Removes the infinite_rec_3 crasher.
1378
Georg Brandl24250812006-06-09 18:45:48 +00001379- The string and unicode methods startswith() and endswith() now accept
1380 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1381
Brett Cannonde3b0522006-06-08 17:00:45 +00001382- Buffer objects, at the C level, never used the char buffer
1383 implementation even when the char buffer for the wrapped object was
1384 explicitly requested (originally returned the read or write buffer).
1385 Now a TypeError is raised if the char buffer is not present but is
1386 requested.
1387
Georg Brandlddbaa662006-06-04 21:56:52 +00001388- Patch #1346214: Statements like "if 0: suite" are now again optimized
1389 away like they were in Python 2.4.
1390
Georg Brandlb7c8f542006-05-27 12:30:25 +00001391- Builtin exceptions are now full-blown new-style classes instead of
1392 instances pretending to be classes, which speeds up exception handling
1393 by about 80% in comparison to 2.5a2.
1394
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001395- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1396 Unicode 4.1.
1397
Georg Brandlf4ef1162006-05-26 18:03:31 +00001398- Patch #921466: sys.path_importer_cache is now used to cache valid and
1399 invalid file paths for the built-in import machinery which leads to
1400 fewer open calls on startup.
1401
Tim Peters696cf432006-05-24 21:10:40 +00001402- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1403 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1404 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1405 the number of input digits (it was and remains linear-time for bases
1406 2, 4, 8, 16 and 32).
1407
Tim Petersb713ec22006-05-23 18:45:30 +00001408- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1409 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1410 an integer close to ``sys.maxint``. This was repaired by patch
1411 #1335972, which also gives a nice speedup.
1412
Richard Jonescebbefc2006-05-23 18:28:17 +00001413- Patch #1337051: reduced size of frame objects.
1414
1415- PyErr_NewException now accepts a tuple of base classes as its
1416 "base" parameter.
1417
Richard Jones7c88dcc2006-05-23 10:37:38 +00001418- Patch #876206: function call speedup by retaining allocated frame
1419 objects.
1420
Georg Brandl7b90e162006-05-18 07:01:27 +00001421- Bug #1462152: file() now checks more thoroughly for invalid mode
1422 strings and removes a possible "U" before passing the mode to the
1423 C library function.
1424
Neal Norwitz1004a532006-05-15 07:17:23 +00001425- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1426
Neal Norwitz373f0a72006-05-15 07:04:36 +00001427- Bug #1487966: Fix SystemError with conditional expression in assignment
1428
Martin v. Löwis879768d2006-05-11 13:28:43 +00001429- WindowsError now has two error code attributes: errno, which carries
1430 the error values from errno.h, and winerror, which carries the error
1431 values from winerror.h. Previous versions put the winerror.h values
1432 (from GetLastError()) into the errno attribute.
1433
Martin v. Löwis77736712006-05-04 05:51:03 +00001434- Patch #1475845: Raise IndentationError for unexpected indent.
1435
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001436- Patch #1479181: split open() and file() from being aliases for each other.
1437
Tim Peters44bd9862006-06-01 13:49:23 +00001438- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1439 methods were always silently ignored by dictionaries when comparing keys.
1440 They are now passed through (except when using the C API function
1441 ``PyDict_GetItem()``, whose semantics did not change).
1442
1443- Bug #1456209: In some obscure cases it was possible for a class with a
1444 custom ``__eq__()`` method to confuse dict internals when class instances
1445 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1446 No, you don't have any code that did this ;-)

1449-----------------
1450
Trent Mick960a3f82006-06-28 20:30:41 +00001451- Bug #1295808: expat symbols should be namespaced in pyexpat
1452
1453- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1454
Brett Cannon6ee7d012006-06-08 16:23:04 +00001455- Change binascii.hexlify to accept a read-only buffer instead of only a char
1456 buffer and actually follow its documentation.
1457
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001458- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1459
Nick Coghlanc649ec52006-05-29 12:43:05 +00001460- Patch #1478788 (modified version): The functional extension module has
1461 been renamed to _functools and a functools Python wrapper module added.
1462 This provides a home for additional function related utilities that are
1463 not specifically about functional programming. See PEP 309.
1464
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001465- Patch #1493701: performance enhancements for struct module.

Georg Brandl378d5922006-05-17 14:26:50 +00001467- Patch #1490224: time.altzone is now set correctly on Cygwin.
1468
Georg Brandl8d3342b2006-05-16 07:38:27 +00001469- Patch #1435422: zlib's compress and decompress objects now have a
1470 copy() method.
1471
Andrew MacIntyre92913322006-06-13 15:04:24 +00001472- Patch #1454481: thread stack size is now tunable at runtime for thread
1473 enabled builds on Windows and systems with Posix threads support.
1474
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001475- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1476 (up to the system limit of 32K characters).
1477
1478- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1479 As a result, these functions now raise WindowsError instead of OSError.
1480
Tim Peters7a822da2006-05-25 21:50:17 +00001481- ``time.clock()`` on Win64 should use the high-performance Windows
1482 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1483 Windows platforms).
1484
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001485- Calling Tk_Init twice is refused if the first call failed as that
1486 may deadlock.
1487
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001488- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1489 accept it without potentially using an uninitialized pointer.
1490
1491- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1492 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1493 patch numbers 1494885 and 1494902]

1497
Gregory P. Smith372b5832006-06-05 18:48:21 +00001498- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1499 parameter is supplied. [SF pybsddb bug #1477863]
1500
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001501- bsddb: the __len__ method of a DB object has been fixed to return correct
1502 results. It could previously incorrectly return 0 in some cases.
1503 Fixes SF bug 1493322 (pybsddb bug 1184012).
1504
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001505- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1506 aborts the db transaction safely when a modifier callback fails.
1507 Fixes SF python patch/bug #1408584.
1508
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001509- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001510 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001511 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1512 database calls that would previously deadlock. [SF python bug #775414]

1543
Tim Peters43898b42006-06-14 04:09:25 +00001544- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1545 guarantee that adjacent triples in the return list always describe
1546 non-adjacent blocks. Previously, a pair of matching blocks could end
1547 up being described by multiple adjacent triples that formed a partition
1548 of the matching pair.

1557
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001558- The wsgiref package has been added to the standard library.
1559
Nick Coghlan676725d2006-06-08 13:54:49 +00001560- The functions update_wrapper() and wraps() have been added to the functools
1561 module. These make it easier to copy relevant metadata from the original
1562 function when writing wrapper functions.
1563
Tim Petersd6a9eef2006-06-05 01:48:21 +00001564- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1565 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001566
Martin v. Löwis3f767792006-06-04 19:36:28 +00001567- Patch #1359618: Speed up charmap encoder by using a trie structure
1568 for lookup.
1569
Tim Petersd609b1a2006-06-02 23:22:51 +00001570- The functions in the ``pprint`` module now sort dictionaries by key
1571 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1572 if and only if its display required more than one line, although that
1573 wasn't documented. The new behavior increases predictability; e.g.,
1574 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1575
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001576- Patch #1497027: try HTTP digest auth before basic auth in urllib2

1585
Georg Brandlb89316f2006-05-17 15:51:16 +00001586- Patch #1180296: Two new functions were added to the locale module:
1587 format_string() to get the effect of "format % items" but locale-aware,
1588 and currency() to format a monetary number with currency sign.

1601 a couple of issues, notably handling of long file names using the
1602 GNU LONGNAME extension.
1603
1604- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1605 new flag when ``name`` is already the name of an option flag.
1606
1607- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1608 package.
1609

1651Core and builtins
1652-----------------
1653
Thomas Heller1b046642006-04-18 18:51:06 +00001654- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1655 by converting these apis from macros into exported functions again:
1656
1657 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1658 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1659 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1660 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1661 PyRun_String Py_CompileString
1662
Martin v. Löwis45294a92006-04-18 06:24:08 +00001663- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1664
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001665- All uses of PyStructSequence_InitType have been changed to initialize
1666 the type objects only once, even if the interpreter is initialized
1667 multiple times.
1668
Neal Norwitz61546162006-04-14 05:20:28 +00001669- Bug #1454485, array.array('u') could crash the interpreter. This was
1670 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1671 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1672
1673- Py_UNICODE is unsigned. It was always documented as unsigned, but
1674 due to a bug had a signed value in previous versions.
1675
Tim Peters3a5e8b12006-04-11 01:44:07 +00001676- Patch #837242: ``id()`` of any Python object always gives a positive
1677 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1678 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001679 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001680 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001681
Tim Peters3a5e8b12006-04-11 01:44:07 +00001682 def __hash__(self):
1683 return id(self) # WRONG
1684
1685 because a hash result must be a (short) Python int but it was always
1686 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001687 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001688 was always usable as a hash value before this patch. That's no longer
1689 necessarily so.
1690
1691- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001692 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001693 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001694 #1454844)
1695
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001696- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1697 involving generators that have paused outside of any ``try`` or ``with``
1698 blocks. (In 2.5a1, a paused generator that was part of a reference
1699 cycle could not be garbage collected, regardless of whether it was
1700 paused in a ``try`` or ``with`` block.)

1730 abusing errno.
1731
Tim Peters711bf302006-04-25 03:31:36 +00001732- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1733 a doctest to be skipped (the code is not run, and the expected output
1734 or exception is ignored).
1735
Nick Coghlanda2268f2006-04-24 04:37:15 +00001736- Fixed contextlib.nested to cope with exceptions being raised and
1737 caught inside exit handlers.
1738
Greg Wardab05edc2006-04-23 03:47:58 +00001739- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1740 hex, octal, or binary; add ``append_const`` action; keep going if
1741 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1742 added ``epilog`` for better help generation).
1743
Tim Peters21fbd572006-04-21 21:18:10 +00001744- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1745 called from a thread spawned as a side effect of importing a module.
1746
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001747- The pydoc module now supports documenting packages contained in
1748 .zip or .egg files.
1749
1750- The pkgutil module now has several new utility functions, such
1751 as ``walk_packages()`` to support working with packages that are either
1752 in the filesystem or zip files.
1753
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001754- The mailbox module can now modify and delete messages from
1755 mailboxes, in addition to simply reading them. Thanks to Gregory
1756 K. Johnson for writing the code, and to the 2005 Google Summer of
1757 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001758
Tim Petersc7605f22006-04-17 21:12:33 +00001759- The ``__del__`` method of class ``local`` in module ``_threading_local``
1760 returned before accomplishing any of its intended cleanup.
1761
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001762- Patch #790710: Add breakpoint command lists in pdb.

Martin v. Löwis4be4e652006-04-17 19:25:49 +00001788- The Makefile now has a reindent target, which runs reindent.py on
1789 the library.
1790
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001791- Patch #1470875: Building Python with MS Free Compiler
1792
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001793- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001794
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001795- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1796 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001797 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001798 CXX from --with-cxx-main, see description in README.
1799
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001800- Patch #1429775: Link extension modules with the shared libpython.
1801
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001802- Fixed a libffi build problem on MIPS systems.
1803
Tim Peters8931ff12006-05-13 23:28:20 +00001804- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1805 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1806 and "%zu" for unsigned integers of type ``size_t``.
1807
Anthony Baxter51bcb682006-04-05 14:51:42 +00001808Tests
1809-----
1810
Nick Coghlanda2268f2006-04-24 04:37:15 +00001811- test_contextlib now checks contextlib.nested can cope with exceptions
1812 being raised and caught inside exit handlers.
1813
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001814- test_cmd_line now checks operation of the -m and -c command switches
1815
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001816- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1817 it separately and by hand. It also wasn't cleaning up its changes to
1818 the current Decimal context.
1819
Thomas Woutersabd08882006-04-26 15:53:30 +00001820- regrtest.py now has a -M option to run tests that test the new limits of
1821 containers, on 64-bit architectures. Running these tests is only sensible
1822 on 64-bit machines with more than two gigabytes of memory. The argument
1823 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001831Documentation
1832-------------
1833
Tim Petersb06d28c2006-05-12 01:57:59 +00001834- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1835
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001836- PEP 343: Added Context Types section to the library reference
1837 and attempted to bring other PEP 343 related documentation into
1838 line with the implementation and/or python-dev discussions.
1839
Tim Peters8dc73d22006-04-24 02:03:16 +00001840- Bug #1337990: clarified that ``doctest`` does not support examples
1841 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001844What's New in Python 2.5 alpha 1?
1845=================================
1846
Anthony Baxterebed3f62006-04-03 15:03:44 +00001847*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001848
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001849Core and builtins
1850-----------------
1851
Nick Coghlan43832302006-04-23 17:04:07 +00001852- PEP 338: -m command line switch now delegates to runpy.run_module
1853 allowing it to support modules in packages and zipfiles
1854
Martin v. Löwisc661b882006-04-20 04:54:23 +00001855- On Windows, .DLL is not an accepted file name extension for
1856 extension modules anymore; extensions are only found if they
1857 end in .PYD.
1858
Martin v. Löwisea62d252006-04-03 10:56:49 +00001859- Bug #1421664: sys.stderr.encoding is now set to the same value as
1860 sys.stdout.encoding.
1861
Neal Norwitz92e212f2006-04-03 04:48:37 +00001862- __import__ accepts keyword arguments.
1863
Georg Brandlccadf842006-03-31 18:54:53 +00001864- Patch #1460496: round() now accepts keyword arguments.
1865
Anthony Baxter262c00a2006-03-30 10:53:17 +00001866- Fixed bug #1459029 - unicode reprs were double-escaped.
1867
Hye-Shik Changd478f342006-03-23 12:32:36 +00001868- Patch #1396919: The system scope threads are reenabled on FreeBSD
1869 5.4 and later versions.
1870
Neal Norwitze98ccf62006-03-23 05:39:47 +00001871- Bug #1115379: Compiling a Unicode string with an encoding declaration
1872 now gives a SyntaxError.
1873
Georg Brandlabd1ff82006-03-18 07:59:59 +00001874- Previously, Python code had no easy way to access the contents of a
1875 cell object. Now, a ``cell_contents`` attribute has been added
1876 (closes patch #1170323).
1877
Tim Peterscf79aac2006-03-16 01:14:46 +00001878- Patch #1123430: Python's small-object allocator now returns an arena to
1879 the system ``free()`` when all memory within an arena becomes unused
1880 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1881 freed. Some applications will see a drop in virtual memory size now,
1882 especially long-running applications that, from time to time, temporarily
1883 use a large number of small objects. Note that when Python returns an
1884 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001885 platform C library will in turn return that memory to the operating system.
1886 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001887 appears to be effective at least on Microsoft C and gcc-based systems.
1888 Thanks to Evan Jones for hard work and patience.
1889
Georg Brandl533ff6f2006-03-08 18:09:27 +00001890- Patch #1434038: property() now uses the getter's docstring if there is
1891 no "doc" argument given. This makes it possible to legitimately use
1892 property() as a decorator to produce a read-only property.
1893
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001894- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1895 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1896 of requiring an int or long in slicing and a few other contexts, enabling
1897 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1898
Neal Norwitz995acdf2006-03-07 05:01:00 +00001899- Fixed various bugs reported by Coverity's Prevent tool.
1900
Brett Cannonbf364092006-03-01 04:25:17 +00001901- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1902 new exception base class, BaseException, which has a new message attribute.
1903 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1904 Raising a string exception now raises a DeprecationWarning.
1905
Thomas Woutersfb609f42006-02-28 16:37:25 +00001906- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1907 explicitly relative, using 'from .module import name' to mean 'from the same
1908 package as this module is in. Imports without dots still default to the
1909 old relative-then-absolute, unless 'from __future__ import
1910 absolute_import' is used.
1911
Brett Cannona7446e32006-02-27 23:39:10 +00001912- Properly check if 'warnings' raises an exception (usually when a filter set
1913 to "error" is triggered) when raising a warning for raising string
1914 exceptions.
1915
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001916- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001917 The name was removed from Include/code.h.
1918
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001919- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001920
Guido van Rossum1968ad32006-02-25 22:38:04 +00001921- Patch 1433928:
1922 - The copy module now "copies" function objects (as atomic objects).
1923 - dict.__getitem__ now looks for a __missing__ hook before raising
1924 KeyError.
1925
Tim Peters84ef21c2006-02-28 20:39:06 +00001926- PEP 343: with statement implemented. Needs ``from __future__ import
1927 with_statement``. Use of 'with' as a variable will generate a warning.
1928 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001929 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001930 The following objects have __context__ methods:
1931 - The built-in file type.
1932 - The thread.LockType type.
1933 - The following types defined by the threading module:
1934 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1935 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001936
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001937- Fix the encodings package codec search function to only search
1938 inside its own package. Fixes problem reported in patch #1433198.
1939
1940 Note: Codec packages should implement and register their own
1941 codec search function. PEP 100 has the details.
1942
Tim Peters9ea89d22006-06-04 03:26:02 +00001943- PEP 353: Using ``Py_ssize_t`` as the index type.
1944
1945- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1946 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1947 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1948 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1949 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001950
Neal Norwitzfc76d632006-01-10 06:03:13 +00001951- Patch #1400181, fix unicode string formatting to not use the locale.
1952 This is how string objects work. u'%f' could use , instead of .
1953 for the decimal point. Now both strings and unicode always use periods.
1954
Neal Norwitz671b9e32006-01-09 07:07:12 +00001955- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1956 configure would break checking curses.h.
1957
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001958- Bug #959576: The pwd module is now builtin. This allows Python to be
1959 built on UNIX platforms without $HOME set.
1960
Neal Norwitzc10978f2005-12-19 06:07:16 +00001961- Bug #1072182, fix some potential problems if characters are signed.
1962
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001963- Bug #889500, fix line number on SyntaxWarning for global declarations.
1964
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001965- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1966
Neal Norwitze7214a12005-12-18 05:03:17 +00001967- Support for converting hex strings to floats no longer works.
1968 This was not portable. float('0x3') now raises a ValueError.
1969
Barry Warsaw2a38a862005-12-18 01:27:35 +00001970- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001971 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001972 is now displayed in interactive prompt banner.
1973
Georg Brandlfa166682005-12-17 21:45:17 +00001974- Implementation of PEP 341 - Unification of try/except and try/finally.
1975 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001976 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001977
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001978- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1979 now encodes backslash correctly.
1980
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001981- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1982
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001983- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001984 and long longs.
1985
Neal Norwitz67715f02005-11-09 06:59:35 +00001986- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001987 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001988 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001989
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001990- Replaced most Unicode charmap codecs with new ones using the
1991 new Unicode translate string feature in the builtin charmap
1992 codec; the codecs were created from the mapping tables available
1993 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1994 encodings now include a mapping for the Apple logo)
1995
Tim Peterse3547fd2005-12-16 23:13:57 +00001996- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001997
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001998- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001999
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002000- A new AST parser implementation was completed. The abstract
2001 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002002 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002003
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002004- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002005 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2006
Neal Norwitz708e51a2005-10-03 04:48:15 +00002007- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2008
Neal Norwitz11bd1192005-10-03 00:54:56 +00002009- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2010 Provide a warning when a directory is passed on the command line.
2011
Neal Norwitz40d37812005-10-02 01:48:49 +00002012- Fix segfault with invalid coding.
2013
2014- SF bug #772896: unknown encoding results in MemoryError.
2015
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002016- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002017 supported a __len__() method which evaluated to False when the iterator
2018 was empty.
2019
Guido van Rossum630db602005-09-20 18:49:54 +00002020- On 64-bit platforms, when __len__() returns a value that cannot be
2021 represented as a C int, raise OverflowError.
2022
Skip Montanarof8948ca2005-09-19 03:54:46 +00002023- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002024 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002025
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002026- SF bug #893549: parsing keyword arguments was broken with a few format
2027 codes.
2028
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002029- Changes donated by Elemental Security to make it work on AIX 5.3
2030 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2031 bug #105470: test_pwd fails on 64bit system (Opteron).
2032
Guido van Rossum539c6622005-09-14 17:49:54 +00002033- Changes donated by Elemental Security to make it work on HP-UX 11 on
2034 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2035
Georg Brandl4550b8d2005-08-26 06:43:52 +00002036- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002037 (fixes bug #1119418).
2038
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002039- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2040
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002041- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2042 exceptions that cause a function to exit.
2043
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002044- The implementation of set() and frozenset() was revised to use its
2045 own internal data structure. Memory consumption is reduced by 1/3
2046 and there are modest speed-ups as well. The API is unchanged.
2047
Tim Petersde7990b2005-07-17 23:45:23 +00002048- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2049
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002050- SF bug #1229429: PyObject_CallMethod failed to decrement some
2051 reference counts in some error exit cases.
2052
Tim Petersecc6e6a2005-07-10 22:30:55 +00002053- SF bug #1185883: Python's small-object memory allocator took over
2054 a block managed by the platform C library whenever a realloc specified
2055 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002056 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002057 portable way to copy data from the C-managed block into Python's
2058 small-object space without risking a memory fault. Python's small-object
2059 realloc now leaves such blocks under the control of the platform C
2060 realloc.

Michael W. Hudsonb8963812005-07-05 15:21:58 +00002062- SF bug #1232517: An overflow error was not detected properly when
2063 attempting to convert a large float to an int in os.utime().
2064
Raymond Hettinger3296e692005-06-29 23:29:56 +00002065- SF bug #1224347: hex longs now print with lowercase letters just
2066 like their int counterparts.
2067
Michael W. Hudson188d4362005-06-20 16:52:57 +00002068- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2069 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2070 interpreter states; back out that fix and do a better job (see
2071 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2072 for a longer write-up of the problem).
2073
Michael W. Hudsondf888462005-06-03 14:41:55 +00002074- SF patch #1180995: marshal now uses a binary format by default when
2075 serializing floats.
2076
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002077- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2078 the routines that promise to produce IEEE 754 binary representations
2079 of floats now simply copy bytes around.
2080
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002081- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2082 278.
2083
Brett Cannonc3647ac2005-04-26 03:45:26 +00002084- patch #1109424: int, long, float, complex, and unicode now check for the
2085 proper magic slot for type conversions when subclassed. Previously the
2086 magic slot was ignored during conversion. Semantics now match the way
2087 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002088 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002089 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002090 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002091
Barry Warsawc8d907c2005-04-19 23:43:40 +00002092- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2093 NULL, now raise an AttributeError when attempting to set or delete the
2094 attribute. Previously a TypeError was raised, but this was inconsistent
2095 with the equivalent pure-Python implementation.
2096
Michael W. Hudson774479c2005-04-18 08:46:17 +00002097- It is now safe to call PyGILState_Release() before
2098 PyEval_InitThreads() (note that if there is reason to believe there
2099 are multiple threads around you still must call PyEval_InitThreads()
2100 before using the Python API; this fix is for extension modules that
2101 have no way of knowing if Python is multi-threaded yet).
2102
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002103- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2104 disabled caused a crash.
2105
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002106- Bug #1165306: instancemethod_new allowed the creation of a method
2107 with im_class == im_self == NULL, which caused a crash when called.
2108
Tim Petersecc6e6a2005-07-10 22:30:55 +00002109- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002110 fixes the crash seen in bug #1165761
2111
Raymond Hettinger96229b12005-03-11 06:49:40 +00002112- Added two new builtins, any() and all().
2113
Brett Cannon409d8f22005-03-05 06:47:57 +00002114- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002115 (e.g., ``class C(): pass`` is no longer a syntax error).
2116 Patch #1176012 added support to the 'parser' module and 'compiler' package
2117 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002118
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002119- Patch #1115086: Support PY_LONGLONG in structmember.
2120
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002121- Bug #1155938: new style classes did not check that __init__() was
2122 returning None.
2123
Tim Petersecc6e6a2005-07-10 22:30:55 +00002124- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002125 ('\') with a specific error message.
2126
Martin v. Löwisff232d72005-03-03 09:24:38 +00002127- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2128
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002129- Bug #1124295: the __name__ attribute of file objects was
2130 inadvertently made inaccessible in restricted mode.
2131
Tim Petersecc6e6a2005-07-10 22:30:55 +00002132- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002133 an ferror() call.
2134
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002135- min() and max() now support key= arguments with the same meaning as in
2136 list.sort().
2137
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002138- The peephole optimizer now performs simple constant folding in expressions:
2139 (2+3) --> (5).
2140
Raymond Hettingera422c342005-01-11 03:03:27 +00002141- set and frozenset objects can now be marshalled. SF #1098985.
2142
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002143- Bug #1077106: Poor argument checking could cause memory corruption
2144 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002145
Jeremy Hyltonab630502005-02-04 18:44:06 +00002146- The parser did not complain about future statements in illegal
2147 positions. It once again reports a syntax error if a future
2148 statement occurs after anything other than a doc string.
2149
Neil Schemenauercf52c072005-08-12 17:34:58 +00002150- Change the %s format specifier for str objects so that it returns a
2151 unicode instance if the argument is not an instance of basestring and
2152 calling __str__ on the argument returns a unicode instance.
2153
Tim Petersf4e69282006-02-27 17:15:31 +00002154- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2155 current thread state when the auto-GIL-state machinery knows about
2156 it (since the thread state is being deleted, continuing to remember it
2157 can't help, but can hurt if another thread happens to get created with
2158 the same thread id).
2159
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002160Extension Modules

2177
2178- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2179
2180- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002181 is deprecated. The undocumented re.engine variable no longer exists.

2185
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002186- The unicodedata module was updated to the 4.1 version of the Unicode
2187 database. The 3.2 version is still available as unicodedata.db_3_2_0
2188 for applications that require this specific version (such as IDNA).
2189
Neal Norwitzb62c4332006-03-04 18:35:47 +00002190- The timing module is no longer built by default. It was deprecated

2211
Martin v. Löwis14694662006-02-03 12:54:16 +00002212- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2213 are reported, the limit on path name lengths is removed, and stat reports
2214 WindowsError now (instead of OSError).
2215
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002216- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

2291 the request code argument, which results in more C-like behaviour
2292 for large or negative values.
2293
Tim Petersecc6e6a2005-07-10 22:30:55 +00002294- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

2336
Raymond Hettingerb2594052004-12-05 09:25:51 +00002337- itertools.islice() now accepts None for the start and step arguments.

Tim Peters112aad32006-07-19 00:03:19 +00002349
Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002350- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2351 been renamed to have only a single underscore prefix. This was done to
2352 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002353
Nick Coghlan43832302006-04-23 17:04:07 +00002354- PEP 338: new module runpy defines a run_module function to support
2355 executing modules which provide access to source code or a code object
2356 via the PEP 302 import mechanisms.
2357
Anthony Baxter93f5b932006-04-03 08:05:07 +00002358- The email module's parsedate_tz function now sets the daylight savings

2366 in attribute values.
2367
Anthony Baxterc51ee692006-04-01 00:57:31 +00002368- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002369 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002370 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002371 module will not be built.
2372
Tim Petersc17976e2006-04-01 00:26:53 +00002373- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2374 aren't officially supported here, and trying to use them will probably
2375 raise an exception some day. But dicts have been allowed, and "mostly
2376 worked", so support for them won't go away without warning.
2377
Georg Brandl338ef7d2006-03-31 18:42:16 +00002378- Bug #1445068: getpass.getpass() can now be given an explicit stream
2379 argument to specify where to write the prompt.
2380
Georg Brandl22ec80b2006-03-31 18:25:44 +00002381- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2390 to make it easier to monitor when daemon threads have completed
2391 processing all enqueued tasks. Patch #1455676.
2392
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002393- popen2.Popen objects now preserve the command in a .cmd attribute.

2396
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002397- email 4.0 package now integrated. This is largely the same as the email 3.0
2398 package that was included in Python 2.3, except that PEP 8 module names are
2399 now used (e.g. mail.message instead of email.Message). The MIME classes
2400 have been moved to a subpackage (e.g. email.mime.text instead of
2401 email.MIMEText). The old names are still supported for now. Several
2402 deprecated Message methods have been removed and lots of bugs have been
2403 fixed. More details can be found in the email package documentation.
2404
Walter Dörwald40108c92006-03-27 08:15:44 +00002405- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2406 (a subclass of tuple) that provides incremental decoders and encoders
2407 (a way to use stateful codecs without the stream API). Python functions
2408 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2409 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2410 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002411
Walter Dörwald067db482006-03-15 22:17:27 +00002412- Patch #1359365: Calling next() on a closed StringIO.String object raises
2413 a ValueError instead of a StopIteration now (like file and cString.String do).
2414 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2415 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002416
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002417- A regrtest option -w was added to re-run failed tests in verbose mode.

2490 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2491 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2492 Ronald L. Rivest offered this advice for Python:
2493
2494 "The consensus of researchers in this area (at least as
2495 expressed at the NIST Hash Function Workshop 10/31/05),
2496 is that SHA-256 is a good choice for the time being, but
2497 that research should continue, and other alternatives may
2498 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002499
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002500- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandl5284b532005-06-26 22:54:58 +00002584
Georg Brandl2f210b62005-06-26 22:09:06 +00002585- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
2586
Georg Brandlfbff1bc2005-06-26 21:36:25 +00002587- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
2588 error messages.
2589
Georg Brandl379f99d2005-06-26 21:09:38 +00002590- Bug #1108948: Cookie.py produced invalid JavaScript code.
2591
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00002592- The tokenize module now detects and reports indentation errors.
2593 Bug #1224621.
2594
Raymond Hettinger68c04532005-06-10 11:05:19 +00002595- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002596 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002597 the generate_tokens() function now accepts a callable argument that
2598 terminates by raising StopIteration.
2599
Georg Brandl9166e1a2005-06-04 09:20:03 +00002600- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2601
Georg Brandl268e61c2005-06-03 14:28:50 +00002602- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2603 component of the path.
2604
Skip Montanaro174dd222005-05-14 20:54:16 +00002605- Patch #1120353: The xmlrpclib module provides better, more transparent,
2606 support for datetime.{datetime,date,time} objects. With use_datetime set
2607 to True, applications shouldn't have to fiddle with the DateTime wrapper
2608 class at all.
2609
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002610- distutils.commands.upload was added to support uploading distribution
2611 files to PyPI.
2612
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002613- distutils.commands.register now encodes the data as UTF-8 before posting
2614 them to PyPI.
2615
Raymond Hettinger267b8682005-03-27 10:47:39 +00002616- decimal operator and comparison methods now return NotImplemented
2617 instead of raising a TypeError when interacting with other types. This
2618 allows other classes to implement __radd__ style methods and have them
2619 work as expected.
2620
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002621- Bug #1163325: Decimal infinities failed to hash. Attempting to
2622 hash a NaN raised an InvalidOperation instead of a TypeError.
2623
Tim Petersecc6e6a2005-07-10 22:30:55 +00002624- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002625 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2626
Martin v. Löwis00a73e72005-03-04 19:40:34 +00002627- Patch #1043890: Add extractall method to tarfile.

2630 to build.
2631
Martin v. Löwis637431b2005-03-03 23:12:42 +00002632- Patch #1103407: Properly deal with tarfile iterators when untarring
2633 symbolic links on Windows.

2656
Raymond Hettingerbab41432005-02-05 01:31:19 +00002657- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2658
Guido van Rossumd0641422005-02-03 15:01:24 +00002659- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2660 disables recursive traversal through instance attributes, which can
2661 be exploited in various ways.
2662
Tim Peterse3547fd2005-12-16 23:13:57 +00002663- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002664 flags on the HTTP listening socket.
2665
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002666- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2667 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2668
Fred Drakefbdeaad2006-07-29 16:56:15 +00002669- Patches #893642, #1039083: add allow_none, encoding arguments to
2670 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002671
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002672- Bug #1110478: Revert os.environ.update to do putenv again.
2673
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002674- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2675
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002676- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2677
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002678- Enhancements to the csv module:
2679
2680 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002681 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002682 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002683 + Dialect parameter parsing has been re-implemented to improve error
2684 reporting.
2685 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2686 dictates.
2687 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002688 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002689 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002690 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2691 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002692 + reader now allows \r characters to be quoted (previously it only allowed
2693 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002694 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002695 + Dialect classes passed to the module are no longer instantiated by
2696 the module before being parsed (the former validation scheme required
2697 this, but the mechanism was unreliable).
2698 + The dialect registry now contains instances of the internal
2699 C-coded dialect type, rather than references to python objects.
2700 + the internal c-coded dialect type is now immutable.
2701 + register_dialect now accepts the same keyword dialect specifications
2702 as the reader and writer, allowing the user to register dialects
2703 without first creating a dialect class.
2704 + a configurable limit to the size of parsed fields has been added -
2705 previously, an unmatched quote character could result in the entire
2706 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002707 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002708 the parser field size limit (returning the former limit). The initial
2709 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002710 + A line_num attribute has been added to the reader object, which tracks
2711 the number of lines read from the source iterator. This is not
2712 the same as the number of records returned, as records can span
2713 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002714 + reader and writer objects were not being registered with the cyclic-GC.
2715 This has been fixed.
2716
Brett Cannone6539c42005-01-08 02:43:53 +00002717- _DummyThread objects in the threading module now delete self.__block that is
2718 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2719 lock primitives tend to be limited in number and thus should not be wasted on
2720 a _DummyThread object. Fixes bug #1089632.
2721
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002722- The imghdr module now detects Exif files.
2723
Raymond Hettinger6065d322004-12-20 23:51:53 +00002724- StringIO.truncate() now correctly adjusts the size attribute.
2725 (Bug #951915).
2726
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002727- locale.py now uses an updated locale alias table (built using
2728 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2729 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002730 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002731
Raymond Hettinger3557f422004-12-07 12:02:02 +00002732- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2733
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002734- the pickle module no longer accepts the deprecated None option in the
2735 args tuple returned by __reduce__().
2736
Brett Cannon84667c02004-12-07 03:25:18 +00002737- optparse now optionally imports gettext. This allows its use in setup.py.
2738
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002739- the pickle module no longer uses the deprecated bin parameter.
2740
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002741- the shelve module no longer uses the deprecated binary parameter.
2742
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002743- the pstats module no longer uses the deprecated ignore() method.
2744
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002745- the filecmp module no longer uses the deprecated use_statcache argument.
2746
Raymond Hettinger664347b2004-12-04 21:21:53 +00002747- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2748 extended or overridden by subclasses. Formerly, the subclassed method would
2749 be ignored by the rest of the module. (Bug #1078905).
2750
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002751- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002752 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002753
Walter Dörwald36733692004-12-22 12:50:50 +00002754- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2755 once when a size argument is given. This prevents a buffer overflow in the
2756 tokenizer with very long source lines.
2757
Barry Warsaw538561e2006-01-01 21:48:54 +00002758- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2759 immediately after creating the object, without any intervening
2760 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002761
Skip Montanaro05885812005-01-16 20:48:27 +00002762- The reconvert.quote function can now emit triple-quoted strings. The
2763 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002764
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002765- ``UserString.MutableString`` now supports negative indices in
2766 ``__setitem__`` and ``__delitem__``
2767
Greg Ward40407942005-03-05 02:53:17 +00002768- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2769 correctly.
2770
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002771- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2772 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2773 character even if the user has passed a size parameter to get a proper
2774 line ending. Remove the special handling of a "\r\n" that has been split
2775 between two lines.
2776
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002777- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2778 about illegal code points. The codec now supports PEP 293 style error
2779 handlers.
2780
Walter Dörwald78a78b02005-09-01 12:04:29 +00002781- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002782 from the input stream, so that the output is a byte string in the correct
2783 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002784
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002785- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2786 considering it exactly like a '*'.
2787
Walter Dörwald007f8df2005-10-09 19:42:27 +00002788- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2789 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002790
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002791- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2792
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002793- Patch #1413711: Certain patterns of differences were making difflib
2794 touch the recursion limit.
2795
Walter Dörwald58917a62006-03-31 15:26:22 +00002796- Bug #947906: An object oriented interface has been added to the calendar
2797 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002798 called as a script (e.g. via ``python -mcalendar``). Localized month and
2799 weekday names can be ouput (even if an exotic encoding is used) using
2800 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002801

2817 The zlib module is now builtin on Windows.
2818
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002819- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2820
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002821- Bug #1189330: configure did not correctly determine the necessary
2822 value of LINKCC if python was built with GCC 4.0.
2823
Trent Mick8321b422005-07-26 02:29:21 +00002824- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2825 vulnerability in zlib 1.2.1 and 1.2.2.
2826
Brett Cannon08cd5982005-04-24 22:26:38 +00002827- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2828 flags that change binary compatibility. Changes were also made to
2829 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002830 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002831
Bob Ippolitoed233462005-03-29 13:47:59 +00002832- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2833 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2834 no longer exists). This configure patch makes things right.
2835
Martin v. Löwise2713be2005-03-08 15:03:08 +00002836- Bug #1158607: Build with --disable-unicode again.
2837
Brett Cannon46d96232005-02-16 00:07:19 +00002838- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2839 defined. Discovered as a result of not being able to build on OS X.
2840
Brett Cannon516592f2004-12-07 00:42:59 +00002841- setup.py now uses the directories specified in LDFLAGS using the -L option
2842 and in CPPFLAGS using the -I option for adding library and include
2843 directories, respectively, for compiling extension modules against. This has
2844 led to the core being compiled using the values in CPPFLAGS. It also removes
2845 the need for the special-casing of both DarwinPorts and Fink for darwin since
2846 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2847 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2848 Fink, ``-I/opt/local/include`` for DarwinPorts).

Brett Cannon43802422005-02-10 20:48:03 +00002850- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2851 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2852 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2853 Closes bug #1096244. Thanks Gregory Bond.

2856-----
2857
Tim Petersc9d78aa2006-03-26 23:27:58 +00002858- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2859 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2860 is obtained via the ``PyObject_`` family, it must be released via the
2861 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2862 always been officially true, but when Python's small-object allocator was
2863 introduced, an attempt was made to cater to a few extension modules
2864 discovered at the time that obtained memory via ``PyObject_New`` but
2865 released it via ``PyMem_DEL``. It's years later, and if such code still
2866 exists it will fail now (probably with segfaults, but calling wrong
2867 low-level memory management functions can yield many symptoms).
2868
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002869- Added a C API for set and frozenset objects.

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002873- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2874 mapping argument now. This string is used as a mapping table. Byte values
2875 greater than the length of the string and 0xFFFE are treated as undefined
2876 mappings.
