614-----------------
615
Neal Norwitz0bcafac2006-09-11 08:51:17 +0000616- Make _PyGILState_NoteThreadState() static, it was not used anywhere
617 outside of pystate.c and should not be necessary.
618
Brett Cannon19d76c52006-09-09 07:18:44 +0000619- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
620 allows calling unicode() on exceptions classes directly to succeed.
621
Georg Brandlecab6232006-09-06 06:47:02 +0000622- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
623 Also make sure that every exception class has __module__ set to
624 'exceptions'.
625
Georg Brandl37a9e572006-09-06 06:09:34 +0000626- Bug #1550983: emit better error messages for erroneous relative

628
Tim Peterscbdd3502006-09-05 01:47:53 +0000629- Overflow checking code in integer division ran afoul of new gcc
630 optimizations. Changed to be more standard-conforming.

Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000637- The return tuple from str.rpartition(sep) is (tail, sep, head) where
638 head is the original string if sep was not found.
639
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000640- Bug #1520864: unpacking singleton tuples in list comprehensions and
641 generator expressions (x for x, in ... ) works again. Fixing this problem
642 required changing the .pyc magic number. This means that .pyc files
643 generated before 2.5c2 will be regenerated.

755Core and builtins
756-----------------
757
Neal Norwitz24b6f202006-09-05 04:43:56 +0000758- Fix infinite recursion when subclassing long and overriding __hash__.
759
760- Fix concatenation (+=) of long strings.
761
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000762- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000763 compared equal or unequal to a string and a UnicodeDecodeError
764 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000765
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000766 Instead, the equal (==) and unequal (!=) comparison operators will
767 now issue a UnicodeWarning and interpret the two objects as
768 unequal. The UnicodeWarning can be filtered as desired using
769 the warning framework, e.g. silenced completely, turned into an
770 exception, logged, etc.
771
772 Note that compare operators other than equal and unequal will still
773 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000774
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000775- Fix segfault when doing string formatting on subclasses of long.
776
777- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
778 with new-style classes.
779
780- Fix bug related to __len__ functions returning negative values with
781 classic classes.
782
783- Patch #1538606, Fix __index__() clipping. There were some problems
784 discovered with the API and how integers that didn't fit into Py_ssize_t
785 were handled. This patch attempts to provide enough alternatives
786 to effectively use __index__.
787
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000788- Bug #1536021: __hash__ may now return long int; the final hash
789 value is obtained by invoking hash on the long int.
790
Thomas Hellerab1049c2006-08-08 17:37:00 +0000791- Bug #1536786: buffer comparison could emit a RuntimeWarning.
792
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000793- Bug #1535165: fixed a segfault in input() and raw_input() when
794 sys.stdin is closed.
795
Thomas Heller74d36f02006-08-04 18:17:40 +0000796- On Windows, the PyErr_Warn function is now exported from
797 the Python dll again.
798
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000799- Bug #1191458: tracing over for loops now produces a line event
800 on each iteration. Fixing this problem required changing the .pyc
801 magic number. This means that .pyc files generated before 2.5c1
802 will be regenerated.
803
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000804- Bug #1333982: string/number constants were inappropriately stored
805 in the byte code and co_consts even if they were not used, ie
806 immediately popped off the stack.
807
Georg Brandle9462c72006-08-04 18:03:37 +0000808- Fixed a reference-counting problem in property().

811Library
812-------
813
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000814- Fix a bug in the ``compiler`` package that caused invalid code to be
815 generated for generator expressions.
816
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000817- The distutils version has been changed to 2.5.0. The change to
818 keep it programmatically in sync with the Python version running
819 the code (introduced in 2.5b3) has been reverted. It will continue
820 to be maintained manually as static string literal.
821
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000822- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000823 and this cannot be converted to the required C type, an exception is
824 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000825 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000826
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000827- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000828 an exception.
829
Tim Peterscbdd3502006-09-05 01:47:53 +0000830- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000831 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000832 workarounds for clocks with low resolution, to stop the code yielding
833 duplicate UUIDs.
834
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000835- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
836 before raising SystemExit, allowing IDLE to honor quit() and exit().
837
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000838- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
839
Georg Brandl7a1af772006-08-14 21:55:28 +0000840- Patch #1536071: trace.py should now find the full module name of a
841 file correctly even on Windows.
842
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000843- logging's atexit hook now runs even if the rest of the module has
844 already been cleaned up.
845
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000846- Bug #1112549, fix DoS attack on cgi.FieldStorage.

Neal Norwitzff4b63b2006-08-04 04:50:21 +0000848- Bug #1531405, format_exception no longer raises an exception if
849 str(exception) raised an exception.
850
Neil Schemenauer06ded092006-08-04 16:20:30 +0000851- Fix a bug in the ``compiler`` package that caused invalid code to be
852 generated for nested functions.

863 raises the correct exceptions.
864
Thomas Heller1ce433e2006-08-14 16:20:04 +0000865- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
866 '-no-stack-protector' compiler flag for OpenBSD has been removed.
867
Thomas Heller86720042006-08-14 11:17:48 +0000868- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
869 uses the _as_parameter_ attribute when objects are passed to foreign
870 function calls. The ctypes version number was changed to 1.0.1.
871
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000872- Bug #1530559, struct.pack raises TypeError where it used to convert.
873 Passing float arguments to struct.pack when integers are expected
874 now triggers a DeprecationWarning.
875
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000876

Martin v. Löwisa09fd6e2006-08-16 12:55:10 +0000900- Bug #1535502, build _hashlib on Windows, and use masm assembler
901 code in OpenSSL.
902
Thomas Hellerdb7b4432006-08-04 19:49:31 +0000903- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000911- New API for Unicode rich comparisons: PyUnicode_RichCompare()
912
Tim Peters4643c2f2006-08-10 22:45:34 +0000913- Bug #1069160. Internal correctness changes were made to
914 ``PyThreadState_SetAsyncExc()``. A test case was added, and
915 the documentation was changed to state that the return value
916 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +0000919What's New in Python 2.5 beta 3?
920================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000921
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000922*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000923
924Core and builtins
925-----------------
926
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000927- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000928 returned a long (see PEP 353).
929
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000930- Bug #1515471: string.replace() accepts character buffers again.
931
Neal Norwitz07aadb12006-07-30 06:55:48 +0000932- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
933 This provides the proper warning for struct.pack().
934 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
935
Neal Norwitz0d62a062006-07-30 06:53:31 +0000936- Patch #1531113: Fix augmented assignment with yield expressions.
937 Also fix a SystemError when trying to assign to yield expressions.
938
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000939- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
940 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
941 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
942 excessive filesystem operations during imports.
943
Tim Petersbc24eee2006-07-27 01:14:53 +0000944- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
945 operations on signed longs that are formally undefined by C.
946 Unfortunately, at least one compiler now cares about that, so complicated
947 the code to make that compiler happy again.
948
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000949- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
950
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000951- Patch #1232023: Stop including current directory in search
952 path on Windows.
953
Neal Norwitze1fdb322006-07-21 05:32:28 +0000954- Fix some potential crashes found with failmalloc.
955
Neal Norwitze7563102006-07-17 01:00:16 +0000956- Fix warnings reported by Klocwork's static analysis tool.
957
Neal Norwitz84be93b2006-07-16 01:50:38 +0000958- Bug #1512814, Fix incorrect lineno's when code within a function
959 had more than 255 blank lines.
960
Georg Brandl9dceedb2006-07-12 15:31:17 +0000961- Patch #1521179: Python now accepts the standard options ``--help`` and
962 ``--version`` as well as ``/?`` on Windows.
963
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000964- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000965 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000966 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000967
Tim Peters112aad32006-07-19 00:03:19 +0000968- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000969 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000970 new ``sys._current_frames()`` returns a dictionary with one entry,
971 mapping the faux "thread id" 0 to the current frame.
972
Ronald Oussoren3075e162006-07-25 20:28:55 +0000973- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000974

Neal Norwitza1f10902006-07-12 07:28:29 +0000976Library
977-------
978
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000979- Correction of patch #1455898: In the mbcs decoder, set final=False
980 for stream decoder, but final=True for the decode function.
981
Georg Brandl07fec3a2006-08-01 18:49:24 +0000982- os.urandom no longer masks unrelated exceptions like SystemExit or
983 KeyboardInterrupt.
984
Tim Peters4643c2f2006-08-10 22:45:34 +0000985- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000986 shutil.copytree on Windows
987
Georg Brandle34ac7c2006-07-30 11:07:23 +0000988- Bug #1002398: The documentation for os.path.sameopenfile now correctly
989 refers to file descriptors, not file objects.
990
Tim Peterscbdd3502006-09-05 01:47:53 +0000991- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000992 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000993 #1513611, and probably others.
994
Georg Brandledd9b0d2006-07-29 09:33:26 +0000995- Bug #1441397: The compiler module now recognizes module and function
996 docstrings correctly as it did in Python 2.4.
997
Tim Peters6f681472006-07-27 23:44:37 +0000998- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
999 lost that tests are sorted by name before being run. This rarely
1000 matters for well-written tests, but can create baffling symptoms if
1001 side effects from one test to the next affect outcomes. ``DocTestFinder``
1002 has been changed to sort the list of tests it returns.
1003
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001004- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001005 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001006
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001007- Bug #978833: Really close underlying socket in _socketobject.close.
1008
Georg Brandldb232dc2006-08-20 13:15:43 +00001009- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1010 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001011
Georg Brandlcf0c1722006-07-26 07:23:32 +00001012- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1013 to recursive calls and call it with the failing package name.
1014
Martin v. Löwis0b483032006-07-25 09:53:12 +00001015- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1016
Georg Brandlc13c34c2006-07-24 14:09:56 +00001017- Patch #1515343: Fix printing of deprecated string exceptions with a
1018 value in the traceback module.
1019
Greg Ward48fae7a2006-07-23 16:05:51 +00001020- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1021
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001022- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1023
Brett Cannoncaebe222006-07-18 04:41:36 +00001024- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1025 argument tuple. For arguments where zero is illegal, the value is forced to
1026 the minimum value that is correct. This is to support an undocumented but
1027 common way people used to fill in inconsequential information in the time
1028 tuple pre-2.4.
1029
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001030- Patch #1220874: Update the binhex module for Mach-O.
1031
Barry Warsawb110bad2006-07-21 14:51:07 +00001032- The email package has improved RFC 2231 support, specifically for
1033 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1034 (name*0=<blah>) parameter continuations. This may change the types of
1035 values returned from email.message.Message.get_param() and friends.
1036 Specifically in some cases where non-encoded continuations were used,
1037 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1038 will just return the string (since non-encoded continuations don't have
1039 charset and language parts).
1040
1041 Also, whereas % values were decoded in all parameter continuations, they are
1042 now only decoded in encoded parameter parts.
1043
Ronald Oussoren3075e162006-07-25 20:28:55 +00001044- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1045
1046- Bug #1517996: IDLE now longer shows the default Tk menu when a
1047 path browser, class browser or debugger is the frontmost window on MacOS X
1048
Barry Warsaw00decd72006-07-27 23:43:15 +00001049- Patch #1520294: Support for getset and member descriptors in types.py,
1050 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1051 of an object against these built-in types and more importantly, for getting
1052 their docstrings printed in the interactive interpreter's help() function.
1053
Ronald Oussoren3075e162006-07-25 20:28:55 +00001054
Neal Norwitza1f10902006-07-12 07:28:29 +00001055Extension Modules
1056-----------------
1057
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001058- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1059 a socket operation on a socket with a timeout, the exception will be
1060 caught correctly. Previously, the exception was not caught.
1061
Thomas Heller1393d6a2006-07-28 21:43:20 +00001062- Patch #1529514: The _ctypes extension is now compiled on more
1063 openbsd target platforms.
1064
Tim Peters9cab5932006-07-28 00:30:00 +00001065- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1066 a memory leak, affecting pickles and deep copies.
1067
Tim Petersbc24eee2006-07-27 01:14:53 +00001068- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001069 Paul Eggert.
1070
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001071- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1072
Thomas Hellerce049a02006-07-14 17:51:14 +00001073- Patch #1521817: Index range checking on ctypes arrays containing
1074 exactly one element enabled again. This allows iterating over these
1075 arrays, without the need to check the array size before.
1076
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001077- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001078 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001079 /dev/null in certain cases; this is now fixed.
1080
Thomas Heller47d7a062006-07-12 08:43:47 +00001081- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1082 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001083
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001084- Because of a misspelled preprocessor symbol, ctypes was always
1085 compiled without thread support; this is now fixed.
1086
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001087- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1088 methods now allow their database parameter to be None as the
1089 sleepycat API allows.
1090
Matt Flemingec926502006-07-28 11:27:27 +00001091- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1092 bluetooth API compared with Linux and FreeBSD.
1093
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001094Tests
1095-----
1096
1097- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1098 how long the test file should take to play. Now accepts taking 2.93 secs
1099 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1100
Georg Brandl4793aa32006-07-28 18:31:39 +00001101- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1102 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1103 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001110Mac
1111---
1112
1113- PythonLauncher now works correctly when the path to the script contains
1114 characters that are treated specially by the shell (such as quotes).
1115
1116- Bug #1527397: PythonLauncher now launches scripts with the working directory
1117 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001118 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001119 expect.

1128-----------------
1129
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001130- Bug #1441486: The literal representation of -(sys.maxint - 1)
1131 again evaluates to a int object, not a long.
1132
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001133- Bug #1501934: The scope of global variables that are locally assigned
1134 using augmented assignment is now correctly determined.
1135
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001136- Bug #927248: Recursive method-wrapper objects can now safely
1137 be released.
1138
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001139- Bug #1417699: Reject locale-specific decimal point in float()
1140 and atof().
1141
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001142- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1143 omit a default "error" argument for NULL pointer. This allows
1144 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001145
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001146- Bug #1519018: 'as' is now validated properly in import statements.
1147
Neal Norwitz28746ab2006-07-09 22:14:42 +00001148- On 64 bit systems, int literals that use less than 64 bits are
1149 now ints rather than longs.
1150
Neal Norwitzed657552006-07-10 00:04:44 +00001151- Bug #1512814, Fix incorrect lineno's when code at module scope
1152 started after line 256.
1153
Tim Peters32a83612006-07-10 21:08:24 +00001154- New function ``sys._current_frames()`` returns a dict mapping thread
1155 id to topmost thread stack frame. This is for expert use, and is
1156 especially useful for debugging application deadlocks. The functionality
1157 was previously available in Fazal Majid's ``threadframe`` extension
1158 module, but it wasn't possible to do this in a wholly threadsafe way from
1159 an extension.

1165 VS 2003.
1166
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001167- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1168
Tim Peters32a83612006-07-10 21:08:24 +00001169- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001170 environment variable to be set in order to the SDK environment
1171 for finding the compiler, include files, etc.

1176
Thomas Woutersadd19112006-07-05 11:03:49 +00001177- string.Template() now correctly handles tuple-values. Previously,
1178 multi-value tuples would raise an exception and single-value tuples would
1179 be treated as the value they contain, instead.
1180
Martin v. Löwisede77f52006-07-03 13:01:35 +00001181- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001192
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001193- Bug #1514703: Only setup canvas window in turtle when the canvas
1194 is created.
1195
Martin v. Löwis7596e832006-07-01 15:33:37 +00001196- Bug #1513223: .close() of a _socketobj now releases the underlying
1197 socket again, which then gets closed as it becomes unreferenced.
1198
Fred Drake10497c82006-06-29 02:57:48 +00001199- Bug #1504333: Make sgmllib support angle brackets in quoted
1200 attribute values.
1201
1202- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1203 sgmllib ('[' and ']' were not accepted).
1204

1206
Brett Cannon53ab5b72006-06-22 16:49:14 +00001207- Bug #1510580: The 'warnings' module improperly required that a Warning
1208 category be either a types.ClassType and a subclass of Warning. The proper
1209 check is just that it is a subclass with Warning as the documentation states.
1210
Georg Brandlad29e632006-06-21 17:45:17 +00001211- The compiler module now correctly compiles the new try-except-finally
1212 statement (bug #1509132).
1213
Neal Norwitz60373cd2006-06-22 06:30:50 +00001214- The wsgiref package is now installed properly on Unix.
1215

1217 shutdown when fileConfig() was called multiple times.
1218
Gerhard Häring762fbd32006-07-02 17:48:30 +00001219- The sqlite3 module did cut off data from the SQLite database at the first
1220 null character before sending it to a custom converter. This has been fixed
1221 now.
1222
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001223Extension Modules
1224-----------------
1225
Tim Peters112aad32006-07-19 00:03:19 +00001226- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1227 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1228 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001229
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001230- Assigning None to pointer type fields in ctypes structures possible
1231 overwrote the wrong fields, this is fixed now.
1232
1233- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1234 on non-Windows platforms.
1235
1236- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1237 integer or long, without range checking.
1238
1239- Patch #1517790: It is now possible to use custom objects in the ctypes
1240 foreign function argtypes sequence as long as they provide a from_param
1241 method, no longer is it required that the object is a ctypes type.
1242
1243- The '_ctypes' extension module now works when Python is configured
1244 with the --without-threads option.
1245
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001246- Bug #1513646: os.access on Windows now correctly determines write
1247 access, again.
1248
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001249- Bug #1512695: cPickle.loads could crash if it was interrupted with
1250 a KeyboardInterrupt.
1251
Neal Norwitza12aa882006-07-06 06:45:08 +00001252- Bug #1296433: parsing XML with a non-default encoding and
1253 a CharacterDataHandler could crash the interpreter in pyexpat.
1254

1259
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001260- Automate Windows build process for the Win64 SSL module.
1261
Tim Peters32a83612006-07-10 21:08:24 +00001262- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001263 Previously, the slight difference could cause compilation errors of the
1264 'zlib' module on systems with more than one version of zlib.
1265
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001266- The MSI compileall step was fixed to also support a TARGETDIR

Anthony Baxter51bcb682006-04-05 14:51:42 +00001296
1297Core and builtins
1298-----------------
1299
Georg Brandla56b9152006-06-19 06:35:54 +00001300- Patch #1507676: Error messages returned by invalid abstract object operations
1301 (such as iterating over an integer) have been improved and now include the
1302 type of the offending object to help with debugging.
1303
Brett Cannonea3912b2006-06-13 21:46:41 +00001304- Bug #992017: A classic class that defined a __coerce__() method that returned
1305 its arguments swapped would infinitely recurse and segfault the interpreter.
1306
Neal Norwitz909eb122006-06-12 02:13:21 +00001307- Fix the socket tests so they can be run concurrently.
1308
Neal Norwitzb9845e72006-06-12 02:11:18 +00001309- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001310 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001311
Brett Cannon22565aa2006-06-09 22:31:23 +00001312- Bug #532646: object.__call__() will continue looking for the __call__
1313 attribute on objects until one without one is found. This leads to recursion
1314 when you take a class and set its __call__ attribute to an instance of the
1315 class. Originally fixed for classic classes, but this fix is for new-style.
1316 Removes the infinite_rec_3 crasher.
1317
Georg Brandl24250812006-06-09 18:45:48 +00001318- The string and unicode methods startswith() and endswith() now accept
1319 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1320
Brett Cannonde3b0522006-06-08 17:00:45 +00001321- Buffer objects, at the C level, never used the char buffer
1322 implementation even when the char buffer for the wrapped object was
1323 explicitly requested (originally returned the read or write buffer).
1324 Now a TypeError is raised if the char buffer is not present but is
1325 requested.
1326
Georg Brandlddbaa662006-06-04 21:56:52 +00001327- Patch #1346214: Statements like "if 0: suite" are now again optimized
1328 away like they were in Python 2.4.
1329
Georg Brandlb7c8f542006-05-27 12:30:25 +00001330- Builtin exceptions are now full-blown new-style classes instead of
1331 instances pretending to be classes, which speeds up exception handling
1332 by about 80% in comparison to 2.5a2.
1333
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001334- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1335 Unicode 4.1.
1336
Georg Brandlf4ef1162006-05-26 18:03:31 +00001337- Patch #921466: sys.path_importer_cache is now used to cache valid and
1338 invalid file paths for the built-in import machinery which leads to
1339 fewer open calls on startup.
1340
Tim Peters696cf432006-05-24 21:10:40 +00001341- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1342 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1343 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1344 the number of input digits (it was and remains linear-time for bases
1345 2, 4, 8, 16 and 32).
1346
Tim Petersb713ec22006-05-23 18:45:30 +00001347- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1348 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1349 an integer close to ``sys.maxint``. This was repaired by patch
1350 #1335972, which also gives a nice speedup.
1351
Richard Jonescebbefc2006-05-23 18:28:17 +00001352- Patch #1337051: reduced size of frame objects.
1353
1354- PyErr_NewException now accepts a tuple of base classes as its
1355 "base" parameter.
1356
Richard Jones7c88dcc2006-05-23 10:37:38 +00001357- Patch #876206: function call speedup by retaining allocated frame
1358 objects.
1359
Georg Brandl7b90e162006-05-18 07:01:27 +00001360- Bug #1462152: file() now checks more thoroughly for invalid mode
1361 strings and removes a possible "U" before passing the mode to the
1362 C library function.
1363
Neal Norwitz1004a532006-05-15 07:17:23 +00001364- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1365
Neal Norwitz373f0a72006-05-15 07:04:36 +00001366- Bug #1487966: Fix SystemError with conditional expression in assignment
1367
Martin v. Löwis879768d2006-05-11 13:28:43 +00001368- WindowsError now has two error code attributes: errno, which carries
1369 the error values from errno.h, and winerror, which carries the error
1370 values from winerror.h. Previous versions put the winerror.h values
1371 (from GetLastError()) into the errno attribute.
1372
Martin v. Löwis77736712006-05-04 05:51:03 +00001373- Patch #1475845: Raise IndentationError for unexpected indent.
1374
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001375- Patch #1479181: split open() and file() from being aliases for each other.
1376
Tim Peters44bd9862006-06-01 13:49:23 +00001377- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1378 methods were always silently ignored by dictionaries when comparing keys.
1379 They are now passed through (except when using the C API function
1380 ``PyDict_GetItem()``, whose semantics did not change).
1381
1382- Bug #1456209: In some obscure cases it was possible for a class with a
1383 custom ``__eq__()`` method to confuse dict internals when class instances
1384 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1385 No, you don't have any code that did this ;-)

1393
Brett Cannon6ee7d012006-06-08 16:23:04 +00001394- Change binascii.hexlify to accept a read-only buffer instead of only a char
1395 buffer and actually follow its documentation.
1396
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001397- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1398
Nick Coghlanc649ec52006-05-29 12:43:05 +00001399- Patch #1478788 (modified version): The functional extension module has
1400 been renamed to _functools and a functools Python wrapper module added.
1401 This provides a home for additional function related utilities that are
1402 not specifically about functional programming. See PEP 309.
1403
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001404- Patch #1493701: performance enhancements for struct module.

1410
Andrew MacIntyre92913322006-06-13 15:04:24 +00001411- Patch #1454481: thread stack size is now tunable at runtime for thread
1412 enabled builds on Windows and systems with Posix threads support.
1413
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001414- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1415 (up to the system limit of 32K characters).
1416
1417- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1418 As a result, these functions now raise WindowsError instead of OSError.
1419
Tim Peters7a822da2006-05-25 21:50:17 +00001420- ``time.clock()`` on Win64 should use the high-performance Windows
1421 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1422 Windows platforms).
1423
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001424- Calling Tk_Init twice is refused if the first call failed as that
1425 may deadlock.
1426
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001427- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1428 accept it without potentially using an uninitialized pointer.
1429
1430- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1431 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

1441 results. It could previously incorrectly return 0 in some cases.
1442 Fixes SF bug 1493322 (pybsddb bug 1184012).
1443
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001444- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1445 aborts the db transaction safely when a modifier callback fails.
1446 Fixes SF python patch/bug #1408584.
1447
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001448- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001449 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001450 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1451 database calls that would previously deadlock. [SF python bug #775414]
1452

Georg Brandl83cc0d02006-06-14 08:50:03 +00001474- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1475 mime.types file for determining MIME types.
1476
Georg Brandl2605ca82006-06-14 06:08:31 +00001477- Bug #1339007: Shelf objects now don't raise an exception in their
1478 __del__ method when initialization failed.
1479
Martin v. Löwisd8251432006-06-14 05:21:04 +00001480- Patch #1455898: The MBCS codec now supports the incremental mode for
1481 double-byte encodings.
1482
Tim Peters43898b42006-06-14 04:09:25 +00001483- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1484 guarantee that adjacent triples in the return list always describe
1485 non-adjacent blocks. Previously, a pair of matching blocks could end
1486 up being described by multiple adjacent triples that formed a partition
1487 of the matching pair.
1488
Greg Ward0e0c9f42006-06-11 16:24:11 +00001489- Bug #1498146: fix optparse to handle Unicode strings in option help,
1490 description, and epilog.
1491
Greg Wardd1c797e2006-06-11 14:42:41 +00001492- Bug #1366250: minor optparse documentation error.
1493
Greg Ward7f547402006-06-11 00:40:49 +00001494- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1495 clarify docs.
1496
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001497- The wsgiref package has been added to the standard library.
1498
Nick Coghlan676725d2006-06-08 13:54:49 +00001499- The functions update_wrapper() and wraps() have been added to the functools
1500 module. These make it easier to copy relevant metadata from the original
1501 function when writing wrapper functions.
1502
Tim Petersd6a9eef2006-06-05 01:48:21 +00001503- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1504 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001505
Martin v. Löwis3f767792006-06-04 19:36:28 +00001506- Patch #1359618: Speed up charmap encoder by using a trie structure
1507 for lookup.
1508
Tim Petersd609b1a2006-06-02 23:22:51 +00001509- The functions in the ``pprint`` module now sort dictionaries by key
1510 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1511 if and only if its display required more than one line, although that
1512 wasn't documented. The new behavior increases predictability; e.g.,
1513 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1514
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001515- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1516 (thanks for J. J. Lee).
1517
Georg Brandl2b330372006-05-28 20:23:12 +00001518- Patch #1496206: improve urllib2 handling of passwords with respect to
1519 default HTTP and HTTPS ports.
1520
George Yoshidaf3c65de2006-05-28 16:39:09 +00001521- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1522
Bob Ippolito7298f272006-05-23 18:43:47 +00001523- Patch #1281707: speed up gzip.readline.
1524
Georg Brandlb89316f2006-05-17 15:51:16 +00001525- Patch #1180296: Two new functions were added to the locale module:
1526 format_string() to get the effect of "format % items" but locale-aware,
1527 and currency() to format a monetary number with currency sign.
1528
Georg Brandle3a25832006-05-17 14:56:04 +00001529- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1530 and several features added, such as speed and geometry control.
1531
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001532- Patch #1488881: add support for external file objects in bz2 compressed
1533 tarfiles.
1534
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001535- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1536 stdout arguments, making it possible to redirect input and output
1537 for remote debugging.
1538
1539- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1540 a couple of issues, notably handling of long file names using the
1541 GNU LONGNAME extension.
1542
1543- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1544 new flag when ``name`` is already the name of an option flag.
1545
1546- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1547 package.
1548
1549- Patch #1472854: make the rlcompleter.Completer class usable on non-
1550 UNIX platforms.
1551
1552- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1553
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001554- Bug #1472827: correctly escape newlines and tabs in attribute values in
1555 the saxutils.XMLGenerator class.

1564
Martin v. Löwisa43190b2006-05-22 09:15:18 +00001565- Patch #1492356: Port to Windows CE.
1566
Neal Norwitz58e28882006-05-19 07:00:58 +00001567- Bug/Patch #1481770: Use .so extension for shared libraries on HP-UX for ia64.
1568
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001569- Patch #1471883: Add --enable-universalsdk.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001585What's New in Python 2.5 alpha 2?
1586=================================
1587
1588*Release date: 27-APR-2006*
1589
1590Core and builtins
1591-----------------
1592
Thomas Heller1b046642006-04-18 18:51:06 +00001593- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1594 by converting these apis from macros into exported functions again:
1595
1596 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1597 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1598 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1599 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1600 PyRun_String Py_CompileString
1601
Martin v. Löwis45294a92006-04-18 06:24:08 +00001602- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1603
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001604- All uses of PyStructSequence_InitType have been changed to initialize
1605 the type objects only once, even if the interpreter is initialized
1606 multiple times.
1607
Neal Norwitz61546162006-04-14 05:20:28 +00001608- Bug #1454485, array.array('u') could crash the interpreter. This was
1609 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1610 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1611
1612- Py_UNICODE is unsigned. It was always documented as unsigned, but
1613 due to a bug had a signed value in previous versions.
1614
Tim Peters3a5e8b12006-04-11 01:44:07 +00001615- Patch #837242: ``id()`` of any Python object always gives a positive
1616 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1617 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001618 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001619 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001620
Tim Peters3a5e8b12006-04-11 01:44:07 +00001621 def __hash__(self):
1622 return id(self) # WRONG
1623
1624 because a hash result must be a (short) Python int but it was always
1625 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001626 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001627 was always usable as a hash value before this patch. That's no longer
1628 necessarily so.
1629
1630- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001631 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001632 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001633 #1454844)
1634
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001635- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1636 involving generators that have paused outside of any ``try`` or ``with``
1637 blocks. (In 2.5a1, a paused generator that was part of a reference
1638 cycle could not be garbage collected, regardless of whether it was
1639 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001640
Anthony Baxter51bcb682006-04-05 14:51:42 +00001641Extension Modules

1643
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001644- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1645 is a macro.
1646
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001647- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1648 fails with an error condition.
1649
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001650- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1651
1652- Bug #1117761: bsddb.*open() no longer raises an exception when using
1653 the cachesize parameter.
1654
1655- Bug #1149413: bsddb.*open() no longer raises an exception when using
1656 a temporary db (file=None) with the 'n' flag to truncate on open.
1657
1658- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1659 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001660
Armin Rigoa9017c32006-04-19 11:50:27 +00001661- Patch #1062014: AF_UNIX sockets under Linux have a special
1662 abstract namespace that is now fully supported.
1663

1665-------
1666
Peter Astrand7d1d4362006-07-14 14:04:45 +00001667- Bug #1223937: subprocess.CalledProcessError reports the exit status
1668 of the process using the returncode attribute, instead of
1669 abusing errno.
1670
Tim Peters711bf302006-04-25 03:31:36 +00001671- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1672 a doctest to be skipped (the code is not run, and the expected output
1673 or exception is ignored).
1674
Nick Coghlanda2268f2006-04-24 04:37:15 +00001675- Fixed contextlib.nested to cope with exceptions being raised and
1676 caught inside exit handlers.
1677
Greg Wardab05edc2006-04-23 03:47:58 +00001678- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1679 hex, octal, or binary; add ``append_const`` action; keep going if
1680 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1681 added ``epilog`` for better help generation).
1682
Tim Peters21fbd572006-04-21 21:18:10 +00001683- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1684 called from a thread spawned as a side effect of importing a module.
1685
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001686- The pydoc module now supports documenting packages contained in
1687 .zip or .egg files.
1688
1689- The pkgutil module now has several new utility functions, such
1690 as ``walk_packages()`` to support working with packages that are either
1691 in the filesystem or zip files.
1692
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001693- The mailbox module can now modify and delete messages from
1694 mailboxes, in addition to simply reading them. Thanks to Gregory
1695 K. Johnson for writing the code, and to the 2005 Google Summer of
1696 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001697
Tim Petersc7605f22006-04-17 21:12:33 +00001698- The ``__del__`` method of class ``local`` in module ``_threading_local``
1699 returned before accomplishing any of its intended cleanup.
1700
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001701- Patch #790710: Add breakpoint command lists in pdb.
1702
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001703- Patch #1063914: Add Tkinter.Misc.clipboard_get().

1706
Anthony Baxtere29002c2006-04-12 12:07:31 +00001707- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1708 Windows. Bug #1469163.
1709
Phillip J. Eby47032112006-04-11 01:07:43 +00001710- The warnings, linecache, inspect, traceback, site, and doctest modules
1711 were updated to work correctly with modules imported from zipfiles or
1712 via other PEP 302 __loader__ objects.
1713
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001714- Patch #1467770: Reduce usage of subprocess._active to processes which
1715 the application hasn't waited on.

1722 direct output to an alternate file-like object.
1723
Anthony Baxter51bcb682006-04-05 14:51:42 +00001724Build
1725-----
1726
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001727- The Makefile now has a reindent target, which runs reindent.py on
1728 the library.
1729
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001730- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis0f48d982006-04-14 14:34:26 +00001734- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1735 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001736 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001737 CXX from --with-cxx-main, see description in README.
1738
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001739- Patch #1429775: Link extension modules with the shared libpython.

Hye-Shik Changf4795c82006-04-26 19:20:26 +00001741- Fixed a libffi build problem on MIPS systems.
1742
Tim Peters8931ff12006-05-13 23:28:20 +00001743- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1744 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1745 and "%zu" for unsigned integers of type ``size_t``.
1746
Anthony Baxter51bcb682006-04-05 14:51:42 +00001747Tests
1748-----
1749
Nick Coghlanda2268f2006-04-24 04:37:15 +00001750- test_contextlib now checks contextlib.nested can cope with exceptions
1751 being raised and caught inside exit handlers.
1752
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001753- test_cmd_line now checks operation of the -m and -c command switches
1754
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001755- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1756 it separately and by hand. It also wasn't cleaning up its changes to
1757 the current Decimal context.
1758
Thomas Woutersabd08882006-04-26 15:53:30 +00001759- regrtest.py now has a -M option to run tests that test the new limits of
1760 containers, on 64-bit architectures. Running these tests is only sensible
1761 on 64-bit machines with more than two gigabytes of memory. The argument
1762 passed is the maximum amount of memory for the tests to use.

Tim Petersb06d28c2006-05-12 01:57:59 +00001773- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1774
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001775- PEP 343: Added Context Types section to the library reference
1776 and attempted to bring other PEP 343 related documentation into
1777 line with the implementation and/or python-dev discussions.
1778
Tim Peters8dc73d22006-04-24 02:03:16 +00001779- Bug #1337990: clarified that ``doctest`` does not support examples

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001788Core and builtins
1789-----------------
1790
Nick Coghlan43832302006-04-23 17:04:07 +00001791- PEP 338: -m command line switch now delegates to runpy.run_module
1792 allowing it to support modules in packages and zipfiles
1793
Martin v. Löwisc661b882006-04-20 04:54:23 +00001794- On Windows, .DLL is not an accepted file name extension for
1795 extension modules anymore; extensions are only found if they
1796 end in .PYD.
1797
Martin v. Löwisea62d252006-04-03 10:56:49 +00001798- Bug #1421664: sys.stderr.encoding is now set to the same value as
1799 sys.stdout.encoding.
1800
Neal Norwitz92e212f2006-04-03 04:48:37 +00001801- __import__ accepts keyword arguments.
1802
Georg Brandlccadf842006-03-31 18:54:53 +00001803- Patch #1460496: round() now accepts keyword arguments.
1804
Anthony Baxter262c00a2006-03-30 10:53:17 +00001805- Fixed bug #1459029 - unicode reprs were double-escaped.
1806
Hye-Shik Changd478f342006-03-23 12:32:36 +00001807- Patch #1396919: The system scope threads are reenabled on FreeBSD
1808 5.4 and later versions.
1809
Neal Norwitze98ccf62006-03-23 05:39:47 +00001810- Bug #1115379: Compiling a Unicode string with an encoding declaration
1811 now gives a SyntaxError.
1812
Georg Brandlabd1ff82006-03-18 07:59:59 +00001813- Previously, Python code had no easy way to access the contents of a
1814 cell object. Now, a ``cell_contents`` attribute has been added
1815 (closes patch #1170323).
1816
Tim Peterscf79aac2006-03-16 01:14:46 +00001817- Patch #1123430: Python's small-object allocator now returns an arena to
1818 the system ``free()`` when all memory within an arena becomes unused
1819 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1820 freed. Some applications will see a drop in virtual memory size now,
1821 especially long-running applications that, from time to time, temporarily
1822 use a large number of small objects. Note that when Python returns an
1823 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001824 platform C library will in turn return that memory to the operating system.
1825 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001826 appears to be effective at least on Microsoft C and gcc-based systems.
1827 Thanks to Evan Jones for hard work and patience.
1828
Georg Brandl533ff6f2006-03-08 18:09:27 +00001829- Patch #1434038: property() now uses the getter's docstring if there is
1830 no "doc" argument given. This makes it possible to legitimately use
1831 property() as a decorator to produce a read-only property.
1832
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001833- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1834 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1835 of requiring an int or long in slicing and a few other contexts, enabling
1836 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1837
Neal Norwitz995acdf2006-03-07 05:01:00 +00001838- Fixed various bugs reported by Coverity's Prevent tool.
1839
Brett Cannonbf364092006-03-01 04:25:17 +00001840- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1841 new exception base class, BaseException, which has a new message attribute.
1842 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1843 Raising a string exception now raises a DeprecationWarning.
1844
Thomas Woutersfb609f42006-02-28 16:37:25 +00001845- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1846 explicitly relative, using 'from .module import name' to mean 'from the same
1847 package as this module is in. Imports without dots still default to the
1848 old relative-then-absolute, unless 'from __future__ import
1849 absolute_import' is used.
1850
Brett Cannona7446e32006-02-27 23:39:10 +00001851- Properly check if 'warnings' raises an exception (usually when a filter set
1852 to "error" is triggered) when raising a warning for raising string
1853 exceptions.
1854
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001855- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001856 The name was removed from Include/code.h.
1857
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001858- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001859
Guido van Rossum1968ad32006-02-25 22:38:04 +00001860- Patch 1433928:
1861 - The copy module now "copies" function objects (as atomic objects).
1862 - dict.__getitem__ now looks for a __missing__ hook before raising
1863 KeyError.
1864
Tim Peters84ef21c2006-02-28 20:39:06 +00001865- PEP 343: with statement implemented. Needs ``from __future__ import
1866 with_statement``. Use of 'with' as a variable will generate a warning.
1867 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001868 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001869 The following objects have __context__ methods:
1870 - The built-in file type.
1871 - The thread.LockType type.
1872 - The following types defined by the threading module:
1873 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1874 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001875
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001876- Fix the encodings package codec search function to only search
1877 inside its own package. Fixes problem reported in patch #1433198.
1878
1879 Note: Codec packages should implement and register their own
1880 codec search function. PEP 100 has the details.
1881
Tim Peters9ea89d22006-06-04 03:26:02 +00001882- PEP 353: Using ``Py_ssize_t`` as the index type.
1883
1884- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1885 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1886 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1887 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1888 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001889
Neal Norwitzfc76d632006-01-10 06:03:13 +00001890- Patch #1400181, fix unicode string formatting to not use the locale.
1891 This is how string objects work. u'%f' could use , instead of .
1892 for the decimal point. Now both strings and unicode always use periods.
1893
Neal Norwitz671b9e32006-01-09 07:07:12 +00001894- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1895 configure would break checking curses.h.
1896
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001897- Bug #959576: The pwd module is now builtin. This allows Python to be
1898 built on UNIX platforms without $HOME set.
1899
Neal Norwitzc10978f2005-12-19 06:07:16 +00001900- Bug #1072182, fix some potential problems if characters are signed.
1901
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001902- Bug #889500, fix line number on SyntaxWarning for global declarations.
1903
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001904- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1905
Neal Norwitze7214a12005-12-18 05:03:17 +00001906- Support for converting hex strings to floats no longer works.
1907 This was not portable. float('0x3') now raises a ValueError.
1908
Barry Warsaw2a38a862005-12-18 01:27:35 +00001909- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001910 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001911 is now displayed in interactive prompt banner.
1912
Georg Brandlfa166682005-12-17 21:45:17 +00001913- Implementation of PEP 341 - Unification of try/except and try/finally.
1914 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001915 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001916
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001917- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1918 now encodes backslash correctly.
1919
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001920- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1921
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001922- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001923 and long longs.
1924
Neal Norwitz67715f02005-11-09 06:59:35 +00001925- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001926 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001927 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001928
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001929- Replaced most Unicode charmap codecs with new ones using the
1930 new Unicode translate string feature in the builtin charmap
1931 codec; the codecs were created from the mapping tables available
1932 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1933 encodings now include a mapping for the Apple logo)
1934
Tim Peterse3547fd2005-12-16 23:13:57 +00001935- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001936
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001937- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001938
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001939- A new AST parser implementation was completed. The abstract
1940 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001941 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001942
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001943- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001944 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1945
Neal Norwitz708e51a2005-10-03 04:48:15 +00001946- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1947
Neal Norwitz11bd1192005-10-03 00:54:56 +00001948- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1949 Provide a warning when a directory is passed on the command line.
1950
Neal Norwitz40d37812005-10-02 01:48:49 +00001951- Fix segfault with invalid coding.
1952
1953- SF bug #772896: unknown encoding results in MemoryError.
1954
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001955- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001956 supported a __len__() method which evaluated to False when the iterator
1957 was empty.
1958
Guido van Rossum630db602005-09-20 18:49:54 +00001959- On 64-bit platforms, when __len__() returns a value that cannot be
1960 represented as a C int, raise OverflowError.
1961
Skip Montanarof8948ca2005-09-19 03:54:46 +00001962- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001963 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001964
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001965- SF bug #893549: parsing keyword arguments was broken with a few format
1966 codes.
1967
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001968- Changes donated by Elemental Security to make it work on AIX 5.3
1969 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1970 bug #105470: test_pwd fails on 64bit system (Opteron).
1971
Guido van Rossum539c6622005-09-14 17:49:54 +00001972- Changes donated by Elemental Security to make it work on HP-UX 11 on
1973 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1974
Georg Brandl4550b8d2005-08-26 06:43:52 +00001975- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001976 (fixes bug #1119418).
1977
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001978- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1979
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001980- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1981 exceptions that cause a function to exit.
1982
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001983- The implementation of set() and frozenset() was revised to use its
1984 own internal data structure. Memory consumption is reduced by 1/3
1985 and there are modest speed-ups as well. The API is unchanged.
1986
Tim Petersde7990b2005-07-17 23:45:23 +00001987- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1988
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001989- SF bug #1229429: PyObject_CallMethod failed to decrement some
1990 reference counts in some error exit cases.
1991
Tim Petersecc6e6a2005-07-10 22:30:55 +00001992- SF bug #1185883: Python's small-object memory allocator took over
1993 a block managed by the platform C library whenever a realloc specified
1994 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001995 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001996 portable way to copy data from the C-managed block into Python's
1997 small-object space without risking a memory fault. Python's small-object
1998 realloc now leaves such blocks under the control of the platform C
1999 realloc.
2000
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002001- SF bug #1232517: An overflow error was not detected properly when
2002 attempting to convert a large float to an int in os.utime().
2003
Raymond Hettinger3296e692005-06-29 23:29:56 +00002004- SF bug #1224347: hex longs now print with lowercase letters just
2005 like their int counterparts.
2006
Michael W. Hudson188d4362005-06-20 16:52:57 +00002007- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2008 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2009 interpreter states; back out that fix and do a better job (see
2010 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2011 for a longer write-up of the problem).
2012
Michael W. Hudsondf888462005-06-03 14:41:55 +00002013- SF patch #1180995: marshal now uses a binary format by default when
2014 serializing floats.
2015
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002016- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2017 the routines that promise to produce IEEE 754 binary representations
2018 of floats now simply copy bytes around.
2019
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002020- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2021 278.
2022
Brett Cannonc3647ac2005-04-26 03:45:26 +00002023- patch #1109424: int, long, float, complex, and unicode now check for the
2024 proper magic slot for type conversions when subclassed. Previously the
2025 magic slot was ignored during conversion. Semantics now match the way
2026 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002027 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002028 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002029 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002030
Barry Warsawc8d907c2005-04-19 23:43:40 +00002031- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2032 NULL, now raise an AttributeError when attempting to set or delete the
2033 attribute. Previously a TypeError was raised, but this was inconsistent
2034 with the equivalent pure-Python implementation.
2035
Michael W. Hudson774479c2005-04-18 08:46:17 +00002036- It is now safe to call PyGILState_Release() before
2037 PyEval_InitThreads() (note that if there is reason to believe there
2038 are multiple threads around you still must call PyEval_InitThreads()
2039 before using the Python API; this fix is for extension modules that
2040 have no way of knowing if Python is multi-threaded yet).
2041
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002042- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2043 disabled caused a crash.
2044
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002045- Bug #1165306: instancemethod_new allowed the creation of a method
2046 with im_class == im_self == NULL, which caused a crash when called.
2047
Tim Petersecc6e6a2005-07-10 22:30:55 +00002048- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002049 fixes the crash seen in bug #1165761
2050

2092
Tim Petersf4e69282006-02-27 17:15:31 +00002093- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2094 current thread state when the auto-GIL-state machinery knows about
2095 it (since the thread state is being deleted, continuing to remember it
2096 can't help, but can hurt if another thread happens to get created with
2097 the same thread id).

2305 in attribute values.
2306
Anthony Baxterc51ee692006-04-01 00:57:31 +00002307- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002308 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002309 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002310 module will not be built.

Tim Petersc17976e2006-04-01 00:26:53 +00002312- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2313 aren't officially supported here, and trying to use them will probably

2335
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002336- email 4.0 package now integrated. This is largely the same as the email 3.0
2337 package that was included in Python 2.3, except that PEP 8 module names are
2338 now used (e.g. mail.message instead of email.Message). The MIME classes
2339 have been moved to a subpackage (e.g. email.mime.text instead of
2340 email.MIMEText). The old names are still supported for now. Several
2341 deprecated Message methods have been removed and lots of bugs have been
2342 fixed. More details can be found in the email package documentation.
2343

2345 (a subclass of tuple) that provides incremental decoders and encoders
2346 (a way to use stateful codecs without the stream API). Python functions
2347 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2348 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2349 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002350

2352 a ValueError instead of a StopIteration now (like file and cString.String do).
2353 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2354 called before (like file and StringIO.StringIO do).

Tim Peterse3547fd2005-12-16 23:13:57 +00002428 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2429 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2430 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2431 Ronald L. Rivest offered this advice for Python:
2432
2433 "The consensus of researchers in this area (at least as
2434 expressed at the NIST Hash Function Workshop 10/31/05),
2435 is that SHA-256 is a good choice for the time being, but
2436 that research should continue, and other alternatives may
2437 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002438
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002439- Added a subset of Fredrik Lundh's ElementTree package. Available

2595
Raymond Hettingerbab41432005-02-05 01:31:19 +00002596- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2597
Guido van Rossumd0641422005-02-03 15:01:24 +00002598- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2599 disables recursive traversal through instance attributes, which can
2600 be exploited in various ways.
2601
Tim Peterse3547fd2005-12-16 23:13:57 +00002602- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002603 flags on the HTTP listening socket.
2604
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002605- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2606 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2607
Fred Drakefbdeaad2006-07-29 16:56:15 +00002608- Patches #893642, #1039083: add allow_none, encoding arguments to
2609 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002610

2614
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002615- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2616
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002617- Enhancements to the csv module:
2618
2619 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002620 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002621 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002622 + Dialect parameter parsing has been re-implemented to improve error
2623 reporting.
2624 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2625 dictates.
2626 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002627 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002628 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002629 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2630 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002631 + reader now allows \r characters to be quoted (previously it only allowed
2632 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002633 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002634 + Dialect classes passed to the module are no longer instantiated by
2635 the module before being parsed (the former validation scheme required
2636 this, but the mechanism was unreliable).
2637 + The dialect registry now contains instances of the internal
2638 C-coded dialect type, rather than references to python objects.
2639 + the internal c-coded dialect type is now immutable.
2640 + register_dialect now accepts the same keyword dialect specifications
2641 as the reader and writer, allowing the user to register dialects
2642 without first creating a dialect class.
2643 + a configurable limit to the size of parsed fields has been added -
2644 previously, an unmatched quote character could result in the entire
2645 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002646 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002647 the parser field size limit (returning the former limit). The initial
2648 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002649 + A line_num attribute has been added to the reader object, which tracks
2650 the number of lines read from the source iterator. This is not
2651 the same as the number of records returned, as records can span
2652 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002653 + reader and writer objects were not being registered with the cyclic-GC.
2654 This has been fixed.
2655
Brett Cannone6539c42005-01-08 02:43:53 +00002656- _DummyThread objects in the threading module now delete self.__block that is
2657 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2658 lock primitives tend to be limited in number and thus should not be wasted on
2659 a _DummyThread object. Fixes bug #1089632.
2660
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002661- The imghdr module now detects Exif files.
2662
Raymond Hettinger6065d322004-12-20 23:51:53 +00002663- StringIO.truncate() now correctly adjusts the size attribute.
2664 (Bug #951915).
2665
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002666- locale.py now uses an updated locale alias table (built using
2667 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2668 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002669 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002670
Raymond Hettinger3557f422004-12-07 12:02:02 +00002671- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2672
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002673- the pickle module no longer accepts the deprecated None option in the
2674 args tuple returned by __reduce__().
2675
Brett Cannon84667c02004-12-07 03:25:18 +00002676- optparse now optionally imports gettext. This allows its use in setup.py.
2677
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002678- the pickle module no longer uses the deprecated bin parameter.
2679
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002680- the shelve module no longer uses the deprecated binary parameter.
2681
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002682- the pstats module no longer uses the deprecated ignore() method.
2683
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002684- the filecmp module no longer uses the deprecated use_statcache argument.
2685
Raymond Hettinger664347b2004-12-04 21:21:53 +00002686- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2687 extended or overridden by subclasses. Formerly, the subclassed method would
2688 be ignored by the rest of the module. (Bug #1078905).
2689
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002690- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002691 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002692
Walter Dörwald36733692004-12-22 12:50:50 +00002693- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2694 once when a size argument is given. This prevents a buffer overflow in the
2695 tokenizer with very long source lines.
2696
Barry Warsaw538561e2006-01-01 21:48:54 +00002697- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2698 immediately after creating the object, without any intervening
2699 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002700
Skip Montanaro05885812005-01-16 20:48:27 +00002701- The reconvert.quote function can now emit triple-quoted strings. The
2702 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002703
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002704- ``UserString.MutableString`` now supports negative indices in
2705 ``__setitem__`` and ``__delitem__``
2706
Greg Ward40407942005-03-05 02:53:17 +00002707- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2708 correctly.
2709
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002710- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2711 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2712 character even if the user has passed a size parameter to get a proper
2713 line ending. Remove the special handling of a "\r\n" that has been split
2714 between two lines.
2715
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002716- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2717 about illegal code points. The codec now supports PEP 293 style error
2718 handlers.
2719
Walter Dörwald78a78b02005-09-01 12:04:29 +00002720- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002721 from the input stream, so that the output is a byte string in the correct
2722 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002723
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002724- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2725 considering it exactly like a '*'.
2726
Walter Dörwald007f8df2005-10-09 19:42:27 +00002727- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2728 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002729
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002730- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2731
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002732- Patch #1413711: Certain patterns of differences were making difflib
2733 touch the recursion limit.
2734
Walter Dörwald58917a62006-03-31 15:26:22 +00002735- Bug #947906: An object oriented interface has been added to the calendar
2736 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002737 called as a script (e.g. via ``python -mcalendar``). Localized month and
2738 weekday names can be ouput (even if an exotic encoding is used) using
2739 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002740
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002741Build
2742-----
2743
Neal Norwitz602d3392006-03-31 08:21:40 +00002744- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2745 by using -mieee gcc option.
2746

2748
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002749- Build support for Win64-AMD64 was added.
2750
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002751- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2752
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002753- Patch #881820: look for openpty and forkpty also in libbsd.
2754
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002755- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2756 The zlib module is now builtin on Windows.
2757
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002758- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2759
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002760- Bug #1189330: configure did not correctly determine the necessary
2761 value of LINKCC if python was built with GCC 4.0.
2762
Trent Mick8321b422005-07-26 02:29:21 +00002763- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2764 vulnerability in zlib 1.2.1 and 1.2.2.
2765
Brett Cannon08cd5982005-04-24 22:26:38 +00002766- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2767 flags that change binary compatibility. Changes were also made to
2768 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002769 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002770
Bob Ippolitoed233462005-03-29 13:47:59 +00002771- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2772 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2773 no longer exists). This configure patch makes things right.
2774
Martin v. Löwise2713be2005-03-08 15:03:08 +00002775- Bug #1158607: Build with --disable-unicode again.
2776
Brett Cannon46d96232005-02-16 00:07:19 +00002777- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2778 defined. Discovered as a result of not being able to build on OS X.
2779
Brett Cannon516592f2004-12-07 00:42:59 +00002780- setup.py now uses the directories specified in LDFLAGS using the -L option
2781 and in CPPFLAGS using the -I option for adding library and include
2782 directories, respectively, for compiling extension modules against. This has
2783 led to the core being compiled using the values in CPPFLAGS. It also removes
2784 the need for the special-casing of both DarwinPorts and Fink for darwin since
2785 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2786 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2787 Fink, ``-I/opt/local/include`` for DarwinPorts).
2788
Brett Cannon43802422005-02-10 20:48:03 +00002789- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2790 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2791 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2792 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002794C API
2795-----
2796
Tim Petersc9d78aa2006-03-26 23:27:58 +00002797- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2798 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2799 is obtained via the ``PyObject_`` family, it must be released via the
2800 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2801 always been officially true, but when Python's small-object allocator was
2802 introduced, an attempt was made to cater to a few extension modules
2803 discovered at the time that obtained memory via ``PyObject_New`` but
2804 released it via ``PyMem_DEL``. It's years later, and if such code still
2805 exists it will fail now (probably with segfaults, but calling wrong
2806 low-level memory management functions can yield many symptoms).
2807
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002808- Added a C API for set and frozenset objects.
2809
Raymond Hettinger66517482004-12-03 11:45:13 +00002810- Removed PyRange_New().
2811
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002812- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2813 mapping argument now. This string is used as a mapping table. Byte values
2814 greater than the length of the string and 0xFFFE are treated as undefined
2815 mappings.
