609-----------------
610
Neal Norwitz0bcafac2006-09-11 08:51:17 +0000611- Make _PyGILState_NoteThreadState() static, it was not used anywhere
612 outside of pystate.c and should not be necessary.
613
Brett Cannon19d76c52006-09-09 07:18:44 +0000614- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
615 allows calling unicode() on exceptions classes directly to succeed.
616
Georg Brandlecab6232006-09-06 06:47:02 +0000617- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
618 Also make sure that every exception class has __module__ set to
619 'exceptions'.
620
Georg Brandl37a9e572006-09-06 06:09:34 +0000621- Bug #1550983: emit better error messages for erroneous relative

623
Tim Peterscbdd3502006-09-05 01:47:53 +0000624- Overflow checking code in integer division ran afoul of new gcc
625 optimizations. Changed to be more standard-conforming.

Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000632- The return tuple from str.rpartition(sep) is (tail, sep, head) where
633 head is the original string if sep was not found.
634
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000635- Bug #1520864: unpacking singleton tuples in list comprehensions and
636 generator expressions (x for x, in ... ) works again. Fixing this problem
637 required changing the .pyc magic number. This means that .pyc files
638 generated before 2.5c2 will be regenerated.

750Core and builtins
751-----------------
752
Neal Norwitz24b6f202006-09-05 04:43:56 +0000753- Fix infinite recursion when subclassing long and overriding __hash__.
754
755- Fix concatenation (+=) of long strings.
756
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000757- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000758 compared equal or unequal to a string and a UnicodeDecodeError
759 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000760
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000761 Instead, the equal (==) and unequal (!=) comparison operators will
762 now issue a UnicodeWarning and interpret the two objects as
763 unequal. The UnicodeWarning can be filtered as desired using
764 the warning framework, e.g. silenced completely, turned into an
765 exception, logged, etc.
766
767 Note that compare operators other than equal and unequal will still
768 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000769
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000770- Fix segfault when doing string formatting on subclasses of long.
771
772- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
773 with new-style classes.
774
775- Fix bug related to __len__ functions returning negative values with
776 classic classes.
777
778- Patch #1538606, Fix __index__() clipping. There were some problems
779 discovered with the API and how integers that didn't fit into Py_ssize_t
780 were handled. This patch attempts to provide enough alternatives
781 to effectively use __index__.
782
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000783- Bug #1536021: __hash__ may now return long int; the final hash
784 value is obtained by invoking hash on the long int.
785
Thomas Hellerab1049c2006-08-08 17:37:00 +0000786- Bug #1536786: buffer comparison could emit a RuntimeWarning.
787
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000788- Bug #1535165: fixed a segfault in input() and raw_input() when
789 sys.stdin is closed.
790
Thomas Heller74d36f02006-08-04 18:17:40 +0000791- On Windows, the PyErr_Warn function is now exported from
792 the Python dll again.
793
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000794- Bug #1191458: tracing over for loops now produces a line event
795 on each iteration. Fixing this problem required changing the .pyc
796 magic number. This means that .pyc files generated before 2.5c1
797 will be regenerated.
798
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000799- Bug #1333982: string/number constants were inappropriately stored
800 in the byte code and co_consts even if they were not used, ie
801 immediately popped off the stack.
802
Georg Brandle9462c72006-08-04 18:03:37 +0000803- Fixed a reference-counting problem in property().

806Library
807-------
808
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000809- Fix a bug in the ``compiler`` package that caused invalid code to be
810 generated for generator expressions.
811
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000812- The distutils version has been changed to 2.5.0. The change to
813 keep it programmatically in sync with the Python version running
814 the code (introduced in 2.5b3) has been reverted. It will continue
815 to be maintained manually as static string literal.
816
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000817- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000818 and this cannot be converted to the required C type, an exception is
819 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000820 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000821
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000822- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000823 an exception.
824
Tim Peterscbdd3502006-09-05 01:47:53 +0000825- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000826 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000827 workarounds for clocks with low resolution, to stop the code yielding
828 duplicate UUIDs.
829
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000830- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
831 before raising SystemExit, allowing IDLE to honor quit() and exit().
832
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000833- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
834
Georg Brandl7a1af772006-08-14 21:55:28 +0000835- Patch #1536071: trace.py should now find the full module name of a
836 file correctly even on Windows.
837
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000838- logging's atexit hook now runs even if the rest of the module has
839 already been cleaned up.
840
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000841- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000842
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000843- Bug #1531405, format_exception no longer raises an exception if
844 str(exception) raised an exception.
845
Neil Schemenauer06ded092006-08-04 16:20:30 +0000846- Fix a bug in the ``compiler`` package that caused invalid code to be
847 generated for nested functions.

859
Thomas Heller1ce433e2006-08-14 16:20:04 +0000860- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
861 '-no-stack-protector' compiler flag for OpenBSD has been removed.
862
Thomas Heller86720042006-08-14 11:17:48 +0000863- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
864 uses the _as_parameter_ attribute when objects are passed to foreign
865 function calls. The ctypes version number was changed to 1.0.1.
866
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000867- Bug #1530559, struct.pack raises TypeError where it used to convert.
868 Passing float arguments to struct.pack when integers are expected
869 now triggers a DeprecationWarning.

Tim Peters4643c2f2006-08-10 22:45:34 +0000908- Bug #1069160. Internal correctness changes were made to
909 ``PyThreadState_SetAsyncExc()``. A test case was added, and
910 the documentation was changed to state that the return value
911 is always 1 (normal) or 0 (if the specified thread wasn't found).

Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000917*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000918
919Core and builtins
920-----------------
921
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000922- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000923 returned a long (see PEP 353).
924
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000925- Bug #1515471: string.replace() accepts character buffers again.
926
Neal Norwitz07aadb12006-07-30 06:55:48 +0000927- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
928 This provides the proper warning for struct.pack().
929 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
930
Neal Norwitz0d62a062006-07-30 06:53:31 +0000931- Patch #1531113: Fix augmented assignment with yield expressions.
932 Also fix a SystemError when trying to assign to yield expressions.
933
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000934- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
935 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
936 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
937 excessive filesystem operations during imports.
938
Tim Petersbc24eee2006-07-27 01:14:53 +0000939- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
940 operations on signed longs that are formally undefined by C.
941 Unfortunately, at least one compiler now cares about that, so complicated
942 the code to make that compiler happy again.
943
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000944- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
945
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000946- Patch #1232023: Stop including current directory in search
947 path on Windows.
948
Neal Norwitze1fdb322006-07-21 05:32:28 +0000949- Fix some potential crashes found with failmalloc.
950
Neal Norwitze7563102006-07-17 01:00:16 +0000951- Fix warnings reported by Klocwork's static analysis tool.
952
Neal Norwitz84be93b2006-07-16 01:50:38 +0000953- Bug #1512814, Fix incorrect lineno's when code within a function
954 had more than 255 blank lines.
955
Georg Brandl9dceedb2006-07-12 15:31:17 +0000956- Patch #1521179: Python now accepts the standard options ``--help`` and
957 ``--version`` as well as ``/?`` on Windows.
958
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000959- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000960 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000961 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000962
Tim Peters112aad32006-07-19 00:03:19 +0000963- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000964 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000965 new ``sys._current_frames()`` returns a dictionary with one entry,
966 mapping the faux "thread id" 0 to the current frame.
967
Ronald Oussoren3075e162006-07-25 20:28:55 +0000968- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000969

Neal Norwitza1f10902006-07-12 07:28:29 +0000971Library
972-------
973
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000974- Correction of patch #1455898: In the mbcs decoder, set final=False
975 for stream decoder, but final=True for the decode function.
976
Georg Brandl07fec3a2006-08-01 18:49:24 +0000977- os.urandom no longer masks unrelated exceptions like SystemExit or
978 KeyboardInterrupt.
979
Tim Peters4643c2f2006-08-10 22:45:34 +0000980- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000981 shutil.copytree on Windows
982
Georg Brandle34ac7c2006-07-30 11:07:23 +0000983- Bug #1002398: The documentation for os.path.sameopenfile now correctly
984 refers to file descriptors, not file objects.
985
Tim Peterscbdd3502006-09-05 01:47:53 +0000986- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000987 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000988 #1513611, and probably others.
989
Georg Brandledd9b0d2006-07-29 09:33:26 +0000990- Bug #1441397: The compiler module now recognizes module and function
991 docstrings correctly as it did in Python 2.4.
992
Tim Peters6f681472006-07-27 23:44:37 +0000993- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
994 lost that tests are sorted by name before being run. This rarely
995 matters for well-written tests, but can create baffling symptoms if
996 side effects from one test to the next affect outcomes. ``DocTestFinder``
997 has been changed to sort the list of tests it returns.
998
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000999- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001000 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001001
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001002- Bug #978833: Really close underlying socket in _socketobject.close.
1003
Georg Brandldb232dc2006-08-20 13:15:43 +00001004- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1005 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001006
Georg Brandlcf0c1722006-07-26 07:23:32 +00001007- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1008 to recursive calls and call it with the failing package name.
1009
Martin v. Löwis0b483032006-07-25 09:53:12 +00001010- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1011
Georg Brandlc13c34c2006-07-24 14:09:56 +00001012- Patch #1515343: Fix printing of deprecated string exceptions with a
1013 value in the traceback module.
1014
Greg Ward48fae7a2006-07-23 16:05:51 +00001015- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1016
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001017- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1018
Brett Cannoncaebe222006-07-18 04:41:36 +00001019- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1020 argument tuple. For arguments where zero is illegal, the value is forced to
1021 the minimum value that is correct. This is to support an undocumented but
1022 common way people used to fill in inconsequential information in the time
1023 tuple pre-2.4.
1024
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001025- Patch #1220874: Update the binhex module for Mach-O.
1026
Barry Warsawb110bad2006-07-21 14:51:07 +00001027- The email package has improved RFC 2231 support, specifically for
1028 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1029 (name*0=<blah>) parameter continuations. This may change the types of
1030 values returned from email.message.Message.get_param() and friends.
1031 Specifically in some cases where non-encoded continuations were used,
1032 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1033 will just return the string (since non-encoded continuations don't have
1034 charset and language parts).
1035
1036 Also, whereas % values were decoded in all parameter continuations, they are
1037 now only decoded in encoded parameter parts.
1038
Ronald Oussoren3075e162006-07-25 20:28:55 +00001039- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1040
1041- Bug #1517996: IDLE now longer shows the default Tk menu when a
1042 path browser, class browser or debugger is the frontmost window on MacOS X
1043
Barry Warsaw00decd72006-07-27 23:43:15 +00001044- Patch #1520294: Support for getset and member descriptors in types.py,
1045 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1046 of an object against these built-in types and more importantly, for getting
1047 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001050Extension Modules
1051-----------------
1052
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001053- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1054 a socket operation on a socket with a timeout, the exception will be
1055 caught correctly. Previously, the exception was not caught.
1056
Thomas Heller1393d6a2006-07-28 21:43:20 +00001057- Patch #1529514: The _ctypes extension is now compiled on more
1058 openbsd target platforms.
1059
Tim Peters9cab5932006-07-28 00:30:00 +00001060- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1061 a memory leak, affecting pickles and deep copies.
1062
Tim Petersbc24eee2006-07-27 01:14:53 +00001063- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001064 Paul Eggert.
1065
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001066- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1067
Thomas Hellerce049a02006-07-14 17:51:14 +00001068- Patch #1521817: Index range checking on ctypes arrays containing
1069 exactly one element enabled again. This allows iterating over these
1070 arrays, without the need to check the array size before.
1071
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001072- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001073 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001074 /dev/null in certain cases; this is now fixed.
1075
Thomas Heller47d7a062006-07-12 08:43:47 +00001076- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1077 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001078
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001079- Because of a misspelled preprocessor symbol, ctypes was always
1080 compiled without thread support; this is now fixed.
1081
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001082- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1083 methods now allow their database parameter to be None as the
1084 sleepycat API allows.
1085
Matt Flemingec926502006-07-28 11:27:27 +00001086- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1087 bluetooth API compared with Linux and FreeBSD.
1088
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001089Tests
1090-----
1091
1092- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1093 how long the test file should take to play. Now accepts taking 2.93 secs
1094 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1095
Georg Brandl4793aa32006-07-28 18:31:39 +00001096- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1097 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1098 run via ``regrtest.py``. Now they do.

1107
1108- PythonLauncher now works correctly when the path to the script contains
1109 characters that are treated specially by the shell (such as quotes).
1110
1111- Bug #1527397: PythonLauncher now launches scripts with the working directory
1112 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001113 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001114 expect.

1123-----------------
1124
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001125- Bug #1441486: The literal representation of -(sys.maxint - 1)
1126 again evaluates to a int object, not a long.
1127
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001128- Bug #1501934: The scope of global variables that are locally assigned
1129 using augmented assignment is now correctly determined.
1130
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001131- Bug #927248: Recursive method-wrapper objects can now safely
1132 be released.
1133
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001134- Bug #1417699: Reject locale-specific decimal point in float()
1135 and atof().
1136
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001137- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1138 omit a default "error" argument for NULL pointer. This allows
1139 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001140
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001141- Bug #1519018: 'as' is now validated properly in import statements.
1142
Neal Norwitz28746ab2006-07-09 22:14:42 +00001143- On 64 bit systems, int literals that use less than 64 bits are
1144 now ints rather than longs.
1145
Neal Norwitzed657552006-07-10 00:04:44 +00001146- Bug #1512814, Fix incorrect lineno's when code at module scope
1147 started after line 256.
1148
Tim Peters32a83612006-07-10 21:08:24 +00001149- New function ``sys._current_frames()`` returns a dict mapping thread
1150 id to topmost thread stack frame. This is for expert use, and is
1151 especially useful for debugging application deadlocks. The functionality
1152 was previously available in Fazal Majid's ``threadframe`` extension
1153 module, but it wasn't possible to do this in a wholly threadsafe way from
1154 an extension.

1160 VS 2003.
1161
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001162- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1163
Tim Peters32a83612006-07-10 21:08:24 +00001164- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001165 environment variable to be set in order to the SDK environment
1166 for finding the compiler, include files, etc.

1171
Thomas Woutersadd19112006-07-05 11:03:49 +00001172- string.Template() now correctly handles tuple-values. Previously,
1173 multi-value tuples would raise an exception and single-value tuples would
1174 be treated as the value they contain, instead.
1175
Martin v. Löwisede77f52006-07-03 13:01:35 +00001176- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1177 even if some data are received.

1183 degrees and radians.
1184
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001185- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001186 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001187

1195 attribute values.
1196
1197- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1198 sgmllib ('[' and ']' were not accepted).
1199

1201
Brett Cannon53ab5b72006-06-22 16:49:14 +00001202- Bug #1510580: The 'warnings' module improperly required that a Warning
1203 category be either a types.ClassType and a subclass of Warning. The proper
1204 check is just that it is a subclass with Warning as the documentation states.
1205
Georg Brandlad29e632006-06-21 17:45:17 +00001206- The compiler module now correctly compiles the new try-except-finally
1207 statement (bug #1509132).
1208

1213
Gerhard Häring762fbd32006-07-02 17:48:30 +00001214- The sqlite3 module did cut off data from the SQLite database at the first
1215 null character before sending it to a custom converter. This has been fixed
1216 now.
1217

1219-----------------
1220
Tim Peters112aad32006-07-19 00:03:19 +00001221- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1222 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1223 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001224
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001225- Assigning None to pointer type fields in ctypes structures possible
1226 overwrote the wrong fields, this is fixed now.
1227
1228- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1229 on non-Windows platforms.
1230
1231- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1232 integer or long, without range checking.
1233
1234- Patch #1517790: It is now possible to use custom objects in the ctypes
1235 foreign function argtypes sequence as long as they provide a from_param
1236 method, no longer is it required that the object is a ctypes type.
1237
1238- The '_ctypes' extension module now works when Python is configured
1239 with the --without-threads option.
1240
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001241- Bug #1513646: os.access on Windows now correctly determines write
1242 access, again.
1243
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001244- Bug #1512695: cPickle.loads could crash if it was interrupted with

1256
Tim Peters32a83612006-07-10 21:08:24 +00001257- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001258 Previously, the slight difference could cause compilation errors of the
1259 'zlib' module on systems with more than one version of zlib.
1260
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001261- The MSI compileall step was fixed to also support a TARGETDIR

Anthony Baxter51bcb682006-04-05 14:51:42 +00001291
1292Core and builtins
1293-----------------
1294
Georg Brandla56b9152006-06-19 06:35:54 +00001295- Patch #1507676: Error messages returned by invalid abstract object operations
1296 (such as iterating over an integer) have been improved and now include the
1297 type of the offending object to help with debugging.
1298
Brett Cannonea3912b2006-06-13 21:46:41 +00001299- Bug #992017: A classic class that defined a __coerce__() method that returned
1300 its arguments swapped would infinitely recurse and segfault the interpreter.
1301
Neal Norwitz909eb122006-06-12 02:13:21 +00001302- Fix the socket tests so they can be run concurrently.
1303
Neal Norwitzb9845e72006-06-12 02:11:18 +00001304- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001305 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001306
Brett Cannon22565aa2006-06-09 22:31:23 +00001307- Bug #532646: object.__call__() will continue looking for the __call__
1308 attribute on objects until one without one is found. This leads to recursion
1309 when you take a class and set its __call__ attribute to an instance of the
1310 class. Originally fixed for classic classes, but this fix is for new-style.
1311 Removes the infinite_rec_3 crasher.
1312
Georg Brandl24250812006-06-09 18:45:48 +00001313- The string and unicode methods startswith() and endswith() now accept
1314 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1315
Brett Cannonde3b0522006-06-08 17:00:45 +00001316- Buffer objects, at the C level, never used the char buffer
1317 implementation even when the char buffer for the wrapped object was
1318 explicitly requested (originally returned the read or write buffer).
1319 Now a TypeError is raised if the char buffer is not present but is
1320 requested.
1321
Georg Brandlddbaa662006-06-04 21:56:52 +00001322- Patch #1346214: Statements like "if 0: suite" are now again optimized
1323 away like they were in Python 2.4.
1324
Georg Brandlb7c8f542006-05-27 12:30:25 +00001325- Builtin exceptions are now full-blown new-style classes instead of
1326 instances pretending to be classes, which speeds up exception handling
1327 by about 80% in comparison to 2.5a2.
1328
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001329- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1330 Unicode 4.1.
1331
Georg Brandlf4ef1162006-05-26 18:03:31 +00001332- Patch #921466: sys.path_importer_cache is now used to cache valid and
1333 invalid file paths for the built-in import machinery which leads to
1334 fewer open calls on startup.
1335
Tim Peters696cf432006-05-24 21:10:40 +00001336- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1337 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1338 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1339 the number of input digits (it was and remains linear-time for bases
1340 2, 4, 8, 16 and 32).
1341
Tim Petersb713ec22006-05-23 18:45:30 +00001342- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1343 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1344 an integer close to ``sys.maxint``. This was repaired by patch
1345 #1335972, which also gives a nice speedup.
1346
Richard Jonescebbefc2006-05-23 18:28:17 +00001347- Patch #1337051: reduced size of frame objects.
1348
1349- PyErr_NewException now accepts a tuple of base classes as its
1350 "base" parameter.
1351
Richard Jones7c88dcc2006-05-23 10:37:38 +00001352- Patch #876206: function call speedup by retaining allocated frame
1353 objects.
1354
Georg Brandl7b90e162006-05-18 07:01:27 +00001355- Bug #1462152: file() now checks more thoroughly for invalid mode
1356 strings and removes a possible "U" before passing the mode to the
1357 C library function.
1358
Neal Norwitz1004a532006-05-15 07:17:23 +00001359- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1360
Neal Norwitz373f0a72006-05-15 07:04:36 +00001361- Bug #1487966: Fix SystemError with conditional expression in assignment
1362
Martin v. Löwis879768d2006-05-11 13:28:43 +00001363- WindowsError now has two error code attributes: errno, which carries
1364 the error values from errno.h, and winerror, which carries the error
1365 values from winerror.h. Previous versions put the winerror.h values
1366 (from GetLastError()) into the errno attribute.
1367
Martin v. Löwis77736712006-05-04 05:51:03 +00001368- Patch #1475845: Raise IndentationError for unexpected indent.
1369
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001370- Patch #1479181: split open() and file() from being aliases for each other.
1371
Tim Peters44bd9862006-06-01 13:49:23 +00001372- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1373 methods were always silently ignored by dictionaries when comparing keys.
1374 They are now passed through (except when using the C API function
1375 ``PyDict_GetItem()``, whose semantics did not change).
1376
1377- Bug #1456209: In some obscure cases it was possible for a class with a
1378 custom ``__eq__()`` method to confuse dict internals when class instances
1379 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1380 No, you don't have any code that did this ;-)

1388
Brett Cannon6ee7d012006-06-08 16:23:04 +00001389- Change binascii.hexlify to accept a read-only buffer instead of only a char
1390 buffer and actually follow its documentation.
1391
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001392- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1393
Nick Coghlanc649ec52006-05-29 12:43:05 +00001394- Patch #1478788 (modified version): The functional extension module has
1395 been renamed to _functools and a functools Python wrapper module added.
1396 This provides a home for additional function related utilities that are
1397 not specifically about functional programming. See PEP 309.
1398
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001399- Patch #1493701: performance enhancements for struct module.

1407 enabled builds on Windows and systems with Posix threads support.
1408
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001409- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1410 (up to the system limit of 32K characters).
1411
1412- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1413 As a result, these functions now raise WindowsError instead of OSError.
1414
Tim Peters7a822da2006-05-25 21:50:17 +00001415- ``time.clock()`` on Win64 should use the high-performance Windows
1416 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1417 Windows platforms).
1418
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001419- Calling Tk_Init twice is refused if the first call failed as that
1420 may deadlock.
1421
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001422- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1423 accept it without potentially using an uninitialized pointer.
1424
1425- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1426 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

1436 results. It could previously incorrectly return 0 in some cases.
1437 Fixes SF bug 1493322 (pybsddb bug 1184012).
1438
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001439- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1440 aborts the db transaction safely when a modifier callback fails.
1441 Fixes SF python patch/bug #1408584.
1442
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001443- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001444 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001445 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1446 database calls that would previously deadlock. [SF python bug #775414]
1447

Georg Brandl2605ca82006-06-14 06:08:31 +00001472- Bug #1339007: Shelf objects now don't raise an exception in their
1473 __del__ method when initialization failed.
1474
Martin v. Löwisd8251432006-06-14 05:21:04 +00001475- Patch #1455898: The MBCS codec now supports the incremental mode for
1476 double-byte encodings.
1477
Tim Peters43898b42006-06-14 04:09:25 +00001478- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1479 guarantee that adjacent triples in the return list always describe
1480 non-adjacent blocks. Previously, a pair of matching blocks could end
1481 up being described by multiple adjacent triples that formed a partition
1482 of the matching pair.
1483
Greg Ward0e0c9f42006-06-11 16:24:11 +00001484- Bug #1498146: fix optparse to handle Unicode strings in option help,
1485 description, and epilog.
1486
Greg Wardd1c797e2006-06-11 14:42:41 +00001487- Bug #1366250: minor optparse documentation error.
1488
Greg Ward7f547402006-06-11 00:40:49 +00001489- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1490 clarify docs.
1491
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001492- The wsgiref package has been added to the standard library.
1493
Nick Coghlan676725d2006-06-08 13:54:49 +00001494- The functions update_wrapper() and wraps() have been added to the functools
1495 module. These make it easier to copy relevant metadata from the original
1496 function when writing wrapper functions.
1497
Tim Petersd6a9eef2006-06-05 01:48:21 +00001498- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1499 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001500
Martin v. Löwis3f767792006-06-04 19:36:28 +00001501- Patch #1359618: Speed up charmap encoder by using a trie structure
1502 for lookup.
1503
Tim Petersd609b1a2006-06-02 23:22:51 +00001504- The functions in the ``pprint`` module now sort dictionaries by key
1505 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1506 if and only if its display required more than one line, although that
1507 wasn't documented. The new behavior increases predictability; e.g.,
1508 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1509
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001510- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1511 (thanks for J. J. Lee).
1512
Georg Brandl2b330372006-05-28 20:23:12 +00001513- Patch #1496206: improve urllib2 handling of passwords with respect to
1514 default HTTP and HTTPS ports.
1515
George Yoshidaf3c65de2006-05-28 16:39:09 +00001516- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1517
Bob Ippolito7298f272006-05-23 18:43:47 +00001518- Patch #1281707: speed up gzip.readline.
1519
Georg Brandlb89316f2006-05-17 15:51:16 +00001520- Patch #1180296: Two new functions were added to the locale module:
1521 format_string() to get the effect of "format % items" but locale-aware,
1522 and currency() to format a monetary number with currency sign.
1523
Georg Brandle3a25832006-05-17 14:56:04 +00001524- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1525 and several features added, such as speed and geometry control.
1526
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001527- Patch #1488881: add support for external file objects in bz2 compressed
1528 tarfiles.
1529
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001530- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1531 stdout arguments, making it possible to redirect input and output
1532 for remote debugging.
1533
1534- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1535 a couple of issues, notably handling of long file names using the
1536 GNU LONGNAME extension.
1537
1538- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1539 new flag when ``name`` is already the name of an option flag.
1540
1541- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1542 package.
1543
1544- Patch #1472854: make the rlcompleter.Completer class usable on non-
1545 UNIX platforms.
1546
1547- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1548
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001549- Bug #1472827: correctly escape newlines and tabs in attribute values in
1550 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001580What's New in Python 2.5 alpha 2?
1581=================================
1582
1583*Release date: 27-APR-2006*
1584
1585Core and builtins
1586-----------------
1587
Thomas Heller1b046642006-04-18 18:51:06 +00001588- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1589 by converting these apis from macros into exported functions again:
1590
1591 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1592 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1593 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1594 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1595 PyRun_String Py_CompileString
1596
Martin v. Löwis45294a92006-04-18 06:24:08 +00001597- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1598
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001599- All uses of PyStructSequence_InitType have been changed to initialize
1600 the type objects only once, even if the interpreter is initialized
1601 multiple times.
1602
Neal Norwitz61546162006-04-14 05:20:28 +00001603- Bug #1454485, array.array('u') could crash the interpreter. This was
1604 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1605 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1606
1607- Py_UNICODE is unsigned. It was always documented as unsigned, but
1608 due to a bug had a signed value in previous versions.
1609
Tim Peters3a5e8b12006-04-11 01:44:07 +00001610- Patch #837242: ``id()`` of any Python object always gives a positive
1611 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1612 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001613 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001614 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001615
Tim Peters3a5e8b12006-04-11 01:44:07 +00001616 def __hash__(self):
1617 return id(self) # WRONG
1618
1619 because a hash result must be a (short) Python int but it was always
1620 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001621 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001622 was always usable as a hash value before this patch. That's no longer
1623 necessarily so.
1624
1625- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001626 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001627 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001628 #1454844)
1629
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001630- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1631 involving generators that have paused outside of any ``try`` or ``with``
1632 blocks. (In 2.5a1, a paused generator that was part of a reference
1633 cycle could not be garbage collected, regardless of whether it was
1634 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001635
Anthony Baxter51bcb682006-04-05 14:51:42 +00001636Extension Modules
1637-----------------
1638
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001639- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1640 is a macro.
1641
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001642- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1643 fails with an error condition.
1644
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001645- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1646
1647- Bug #1117761: bsddb.*open() no longer raises an exception when using
1648 the cachesize parameter.
1649
1650- Bug #1149413: bsddb.*open() no longer raises an exception when using
1651 a temporary db (file=None) with the 'n' flag to truncate on open.
1652
1653- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1654 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001655
Armin Rigoa9017c32006-04-19 11:50:27 +00001656- Patch #1062014: AF_UNIX sockets under Linux have a special
1657 abstract namespace that is now fully supported.

Peter Astrand7d1d4362006-07-14 14:04:45 +00001662- Bug #1223937: subprocess.CalledProcessError reports the exit status
1663 of the process using the returncode attribute, instead of
1664 abusing errno.
1665
Tim Peters711bf302006-04-25 03:31:36 +00001666- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1667 a doctest to be skipped (the code is not run, and the expected output
1668 or exception is ignored).
1669
Nick Coghlanda2268f2006-04-24 04:37:15 +00001670- Fixed contextlib.nested to cope with exceptions being raised and
1671 caught inside exit handlers.
1672
Greg Wardab05edc2006-04-23 03:47:58 +00001673- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1674 hex, octal, or binary; add ``append_const`` action; keep going if
1675 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1676 added ``epilog`` for better help generation).
1677
Tim Peters21fbd572006-04-21 21:18:10 +00001678- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1679 called from a thread spawned as a side effect of importing a module.
1680
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001681- The pydoc module now supports documenting packages contained in
1682 .zip or .egg files.
1683
1684- The pkgutil module now has several new utility functions, such
1685 as ``walk_packages()`` to support working with packages that are either
1686 in the filesystem or zip files.
1687
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001688- The mailbox module can now modify and delete messages from
1689 mailboxes, in addition to simply reading them. Thanks to Gregory
1690 K. Johnson for writing the code, and to the 2005 Google Summer of
1691 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001692
Tim Petersc7605f22006-04-17 21:12:33 +00001693- The ``__del__`` method of class ``local`` in module ``_threading_local``
1694 returned before accomplishing any of its intended cleanup.
1695
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001696- Patch #790710: Add breakpoint command lists in pdb.
1697
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001698- Patch #1063914: Add Tkinter.Misc.clipboard_get().

1701
Anthony Baxtere29002c2006-04-12 12:07:31 +00001702- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1703 Windows. Bug #1469163.
1704
Phillip J. Eby47032112006-04-11 01:07:43 +00001705- The warnings, linecache, inspect, traceback, site, and doctest modules
1706 were updated to work correctly with modules imported from zipfiles or
1707 via other PEP 302 __loader__ objects.
1708
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001709- Patch #1467770: Reduce usage of subprocess._active to processes which
1710 the application hasn't waited on.

1721
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001722- The Makefile now has a reindent target, which runs reindent.py on
1723 the library.
1724
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001725- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis0f48d982006-04-14 14:34:26 +00001729- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1730 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001731 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001732 CXX from --with-cxx-main, see description in README.
1733
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001734- Patch #1429775: Link extension modules with the shared libpython.

1737
Tim Peters8931ff12006-05-13 23:28:20 +00001738- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1739 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1740 and "%zu" for unsigned integers of type ``size_t``.
1741
Anthony Baxter51bcb682006-04-05 14:51:42 +00001742Tests
1743-----
1744
Nick Coghlanda2268f2006-04-24 04:37:15 +00001745- test_contextlib now checks contextlib.nested can cope with exceptions
1746 being raised and caught inside exit handlers.
1747
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001748- test_cmd_line now checks operation of the -m and -c command switches
1749
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001750- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1751 it separately and by hand. It also wasn't cleaning up its changes to
1752 the current Decimal context.
1753
Thomas Woutersabd08882006-04-26 15:53:30 +00001754- regrtest.py now has a -M option to run tests that test the new limits of
1755 containers, on 64-bit architectures. Running these tests is only sensible
1756 on 64-bit machines with more than two gigabytes of memory. The argument
1757 passed is the maximum amount of memory for the tests to use.

1784-----------------
1785
Nick Coghlan43832302006-04-23 17:04:07 +00001786- PEP 338: -m command line switch now delegates to runpy.run_module
1787 allowing it to support modules in packages and zipfiles
1788
Martin v. Löwisc661b882006-04-20 04:54:23 +00001789- On Windows, .DLL is not an accepted file name extension for
1790 extension modules anymore; extensions are only found if they
1791 end in .PYD.
1792
Martin v. Löwisea62d252006-04-03 10:56:49 +00001793- Bug #1421664: sys.stderr.encoding is now set to the same value as
1794 sys.stdout.encoding.
1795
Neal Norwitz92e212f2006-04-03 04:48:37 +00001796- __import__ accepts keyword arguments.
1797
Georg Brandlccadf842006-03-31 18:54:53 +00001798- Patch #1460496: round() now accepts keyword arguments.
1799
Anthony Baxter262c00a2006-03-30 10:53:17 +00001800- Fixed bug #1459029 - unicode reprs were double-escaped.
1801
Hye-Shik Changd478f342006-03-23 12:32:36 +00001802- Patch #1396919: The system scope threads are reenabled on FreeBSD
1803 5.4 and later versions.
1804
Neal Norwitze98ccf62006-03-23 05:39:47 +00001805- Bug #1115379: Compiling a Unicode string with an encoding declaration
1806 now gives a SyntaxError.
1807
Georg Brandlabd1ff82006-03-18 07:59:59 +00001808- Previously, Python code had no easy way to access the contents of a
1809 cell object. Now, a ``cell_contents`` attribute has been added
1810 (closes patch #1170323).
1811
Tim Peterscf79aac2006-03-16 01:14:46 +00001812- Patch #1123430: Python's small-object allocator now returns an arena to
1813 the system ``free()`` when all memory within an arena becomes unused
1814 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1815 freed. Some applications will see a drop in virtual memory size now,
1816 especially long-running applications that, from time to time, temporarily
1817 use a large number of small objects. Note that when Python returns an
1818 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001819 platform C library will in turn return that memory to the operating system.
1820 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001821 appears to be effective at least on Microsoft C and gcc-based systems.
1822 Thanks to Evan Jones for hard work and patience.
1823
Georg Brandl533ff6f2006-03-08 18:09:27 +00001824- Patch #1434038: property() now uses the getter's docstring if there is
1825 no "doc" argument given. This makes it possible to legitimately use
1826 property() as a decorator to produce a read-only property.
1827
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001828- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1829 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1830 of requiring an int or long in slicing and a few other contexts, enabling
1831 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1832
Neal Norwitz995acdf2006-03-07 05:01:00 +00001833- Fixed various bugs reported by Coverity's Prevent tool.
1834
Brett Cannonbf364092006-03-01 04:25:17 +00001835- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1836 new exception base class, BaseException, which has a new message attribute.
1837 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1838 Raising a string exception now raises a DeprecationWarning.
1839
Thomas Woutersfb609f42006-02-28 16:37:25 +00001840- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1841 explicitly relative, using 'from .module import name' to mean 'from the same
1842 package as this module is in. Imports without dots still default to the
1843 old relative-then-absolute, unless 'from __future__ import
1844 absolute_import' is used.
1845
Brett Cannona7446e32006-02-27 23:39:10 +00001846- Properly check if 'warnings' raises an exception (usually when a filter set
1847 to "error" is triggered) when raising a warning for raising string
1848 exceptions.
1849
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001850- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001851 The name was removed from Include/code.h.
1852
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001853- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001854
Guido van Rossum1968ad32006-02-25 22:38:04 +00001855- Patch 1433928:
1856 - The copy module now "copies" function objects (as atomic objects).
1857 - dict.__getitem__ now looks for a __missing__ hook before raising
1858 KeyError.
1859
Tim Peters84ef21c2006-02-28 20:39:06 +00001860- PEP 343: with statement implemented. Needs ``from __future__ import
1861 with_statement``. Use of 'with' as a variable will generate a warning.
1862 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001863 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001864 The following objects have __context__ methods:
1865 - The built-in file type.
1866 - The thread.LockType type.
1867 - The following types defined by the threading module:
1868 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1869 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001870
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001871- Fix the encodings package codec search function to only search
1872 inside its own package. Fixes problem reported in patch #1433198.
1873
1874 Note: Codec packages should implement and register their own
1875 codec search function. PEP 100 has the details.
1876
Tim Peters9ea89d22006-06-04 03:26:02 +00001877- PEP 353: Using ``Py_ssize_t`` as the index type.
1878
1879- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1880 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1881 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1882 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1883 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001884
Neal Norwitzfc76d632006-01-10 06:03:13 +00001885- Patch #1400181, fix unicode string formatting to not use the locale.
1886 This is how string objects work. u'%f' could use , instead of .
1887 for the decimal point. Now both strings and unicode always use periods.
1888
Neal Norwitz671b9e32006-01-09 07:07:12 +00001889- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1890 configure would break checking curses.h.
1891
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001892- Bug #959576: The pwd module is now builtin. This allows Python to be
1893 built on UNIX platforms without $HOME set.
1894
Neal Norwitzc10978f2005-12-19 06:07:16 +00001895- Bug #1072182, fix some potential problems if characters are signed.
1896
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001897- Bug #889500, fix line number on SyntaxWarning for global declarations.
1898
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001899- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1900
Neal Norwitze7214a12005-12-18 05:03:17 +00001901- Support for converting hex strings to floats no longer works.
1902 This was not portable. float('0x3') now raises a ValueError.
1903
Barry Warsaw2a38a862005-12-18 01:27:35 +00001904- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001905 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001906 is now displayed in interactive prompt banner.
1907
Georg Brandlfa166682005-12-17 21:45:17 +00001908- Implementation of PEP 341 - Unification of try/except and try/finally.
1909 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001910 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001911
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001912- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1913 now encodes backslash correctly.
1914
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001915- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1916
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001917- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001918 and long longs.
1919
Neal Norwitz67715f02005-11-09 06:59:35 +00001920- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001921 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001922 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001923
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001924- Replaced most Unicode charmap codecs with new ones using the
1925 new Unicode translate string feature in the builtin charmap
1926 codec; the codecs were created from the mapping tables available
1927 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1928 encodings now include a mapping for the Apple logo)
1929
Tim Peterse3547fd2005-12-16 23:13:57 +00001930- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001931
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001932- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001933
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001934- A new AST parser implementation was completed. The abstract
1935 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001936 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001937
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001938- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001939 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1940
Neal Norwitz708e51a2005-10-03 04:48:15 +00001941- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1942
Neal Norwitz11bd1192005-10-03 00:54:56 +00001943- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1944 Provide a warning when a directory is passed on the command line.
1945
Neal Norwitz40d37812005-10-02 01:48:49 +00001946- Fix segfault with invalid coding.
1947
1948- SF bug #772896: unknown encoding results in MemoryError.
1949
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001950- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001951 supported a __len__() method which evaluated to False when the iterator
1952 was empty.
1953
Guido van Rossum630db602005-09-20 18:49:54 +00001954- On 64-bit platforms, when __len__() returns a value that cannot be
1955 represented as a C int, raise OverflowError.
1956
Skip Montanarof8948ca2005-09-19 03:54:46 +00001957- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001958 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001959
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001960- SF bug #893549: parsing keyword arguments was broken with a few format
1961 codes.
1962
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001963- Changes donated by Elemental Security to make it work on AIX 5.3
1964 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1965 bug #105470: test_pwd fails on 64bit system (Opteron).
1966
Guido van Rossum539c6622005-09-14 17:49:54 +00001967- Changes donated by Elemental Security to make it work on HP-UX 11 on
1968 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1969
Georg Brandl4550b8d2005-08-26 06:43:52 +00001970- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001971 (fixes bug #1119418).
1972
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001973- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1974
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001975- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1976 exceptions that cause a function to exit.
1977
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001978- The implementation of set() and frozenset() was revised to use its
1979 own internal data structure. Memory consumption is reduced by 1/3
1980 and there are modest speed-ups as well. The API is unchanged.
1981
Tim Petersde7990b2005-07-17 23:45:23 +00001982- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1983
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001984- SF bug #1229429: PyObject_CallMethod failed to decrement some
1985 reference counts in some error exit cases.
1986
Tim Petersecc6e6a2005-07-10 22:30:55 +00001987- SF bug #1185883: Python's small-object memory allocator took over
1988 a block managed by the platform C library whenever a realloc specified
1989 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001990 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001991 portable way to copy data from the C-managed block into Python's
1992 small-object space without risking a memory fault. Python's small-object
1993 realloc now leaves such blocks under the control of the platform C
1994 realloc.
1995
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001996- SF bug #1232517: An overflow error was not detected properly when
1997 attempting to convert a large float to an int in os.utime().
1998
Raymond Hettinger3296e692005-06-29 23:29:56 +00001999- SF bug #1224347: hex longs now print with lowercase letters just
2000 like their int counterparts.
2001
Michael W. Hudson188d4362005-06-20 16:52:57 +00002002- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2003 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2004 interpreter states; back out that fix and do a better job (see
2005 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2006 for a longer write-up of the problem).
2007
Michael W. Hudsondf888462005-06-03 14:41:55 +00002008- SF patch #1180995: marshal now uses a binary format by default when
2009 serializing floats.
2010
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002011- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2012 the routines that promise to produce IEEE 754 binary representations
2013 of floats now simply copy bytes around.
2014
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002015- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2016 278.
2017
Brett Cannonc3647ac2005-04-26 03:45:26 +00002018- patch #1109424: int, long, float, complex, and unicode now check for the
2019 proper magic slot for type conversions when subclassed. Previously the
2020 magic slot was ignored during conversion. Semantics now match the way
2021 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002022 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002023 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002024 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002025
Barry Warsawc8d907c2005-04-19 23:43:40 +00002026- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2027 NULL, now raise an AttributeError when attempting to set or delete the
2028 attribute. Previously a TypeError was raised, but this was inconsistent
2029 with the equivalent pure-Python implementation.
2030
Michael W. Hudson774479c2005-04-18 08:46:17 +00002031- It is now safe to call PyGILState_Release() before
2032 PyEval_InitThreads() (note that if there is reason to believe there
2033 are multiple threads around you still must call PyEval_InitThreads()
2034 before using the Python API; this fix is for extension modules that
2035 have no way of knowing if Python is multi-threaded yet).
2036
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002037- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2038 disabled caused a crash.
2039
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002040- Bug #1165306: instancemethod_new allowed the creation of a method
2041 with im_class == im_self == NULL, which caused a crash when called.
2042
Tim Petersecc6e6a2005-07-10 22:30:55 +00002043- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002044 fixes the crash seen in bug #1165761
2045
Raymond Hettinger96229b12005-03-11 06:49:40 +00002046- Added two new builtins, any() and all().

2089 current thread state when the auto-GIL-state machinery knows about
2090 it (since the thread state is being deleted, continuing to remember it
2091 can't help, but can hurt if another thread happens to get created with
2092 the same thread id).

2301
Anthony Baxterc51ee692006-04-01 00:57:31 +00002302- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002303 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002304 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002305 module will not be built.

Tim Petersc17976e2006-04-01 00:26:53 +00002307- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2308 aren't officially supported here, and trying to use them will probably

2330
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002331- email 4.0 package now integrated. This is largely the same as the email 3.0
2332 package that was included in Python 2.3, except that PEP 8 module names are
2333 now used (e.g. mail.message instead of email.Message). The MIME classes
2334 have been moved to a subpackage (e.g. email.mime.text instead of
2335 email.MIMEText). The old names are still supported for now. Several
2336 deprecated Message methods have been removed and lots of bugs have been
2337 fixed. More details can be found in the email package documentation.

2340 (a subclass of tuple) that provides incremental decoders and encoders
2341 (a way to use stateful codecs without the stream API). Python functions
2342 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2343 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2344 have been added.

2347 a ValueError instead of a StopIteration now (like file and cString.String do).
2348 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2349 called before (like file and StringIO.StringIO do).

Tim Peterse3547fd2005-12-16 23:13:57 +00002423 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2424 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2425 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2426 Ronald L. Rivest offered this advice for Python:
2427
2428 "The consensus of researchers in this area (at least as
2429 expressed at the NIST Hash Function Workshop 10/31/05),
2430 is that SHA-256 is a good choice for the time being, but
2431 that research should continue, and other alternatives may
2432 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002433
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002434- Added a subset of Fredrik Lundh's ElementTree package. Available

2580
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00002581- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
2582
Martin v. Löwisdf241532005-03-03 08:17:42 +00002583- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
2584

2588
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00002589- Patch #1049151: xdrlib now unpacks booleans as True or False.
2590
Raymond Hettingerbab41432005-02-05 01:31:19 +00002591- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2592
Guido van Rossumd0641422005-02-03 15:01:24 +00002593- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2594 disables recursive traversal through instance attributes, which can
2595 be exploited in various ways.
2596
Tim Peterse3547fd2005-12-16 23:13:57 +00002597- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002598 flags on the HTTP listening socket.
2599
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002600- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2601 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2602
Fred Drakefbdeaad2006-07-29 16:56:15 +00002603- Patches #893642, #1039083: add allow_none, encoding arguments to
2604 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002605

2609
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002610- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2611
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002612- Enhancements to the csv module:
2613
2614 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002615 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002616 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002617 + Dialect parameter parsing has been re-implemented to improve error
2618 reporting.
2619 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2620 dictates.
2621 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002622 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002623 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002624 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2625 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002626 + reader now allows \r characters to be quoted (previously it only allowed
2627 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002628 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002629 + Dialect classes passed to the module are no longer instantiated by
2630 the module before being parsed (the former validation scheme required
2631 this, but the mechanism was unreliable).
2632 + The dialect registry now contains instances of the internal
2633 C-coded dialect type, rather than references to python objects.
2634 + the internal c-coded dialect type is now immutable.
2635 + register_dialect now accepts the same keyword dialect specifications
2636 as the reader and writer, allowing the user to register dialects
2637 without first creating a dialect class.
2638 + a configurable limit to the size of parsed fields has been added -
2639 previously, an unmatched quote character could result in the entire
2640 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002641 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002642 the parser field size limit (returning the former limit). The initial
2643 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002644 + A line_num attribute has been added to the reader object, which tracks
2645 the number of lines read from the source iterator. This is not
2646 the same as the number of records returned, as records can span
2647 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002648 + reader and writer objects were not being registered with the cyclic-GC.
2649 This has been fixed.
2650
Brett Cannone6539c42005-01-08 02:43:53 +00002651- _DummyThread objects in the threading module now delete self.__block that is
2652 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2653 lock primitives tend to be limited in number and thus should not be wasted on
2654 a _DummyThread object. Fixes bug #1089632.
2655
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002656- The imghdr module now detects Exif files.
2657
Raymond Hettinger6065d322004-12-20 23:51:53 +00002658- StringIO.truncate() now correctly adjusts the size attribute.
2659 (Bug #951915).
2660
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002661- locale.py now uses an updated locale alias table (built using
2662 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2663 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002664 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002665
Raymond Hettinger3557f422004-12-07 12:02:02 +00002666- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2667
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002668- the pickle module no longer accepts the deprecated None option in the
2669 args tuple returned by __reduce__().
2670
Brett Cannon84667c02004-12-07 03:25:18 +00002671- optparse now optionally imports gettext. This allows its use in setup.py.
2672
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002673- the pickle module no longer uses the deprecated bin parameter.
2674
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002675- the shelve module no longer uses the deprecated binary parameter.
2676
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002677- the pstats module no longer uses the deprecated ignore() method.
2678
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002679- the filecmp module no longer uses the deprecated use_statcache argument.
2680
Raymond Hettinger664347b2004-12-04 21:21:53 +00002681- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2682 extended or overridden by subclasses. Formerly, the subclassed method would
2683 be ignored by the rest of the module. (Bug #1078905).
2684
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002685- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002686 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002687
Walter Dörwald36733692004-12-22 12:50:50 +00002688- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2689 once when a size argument is given. This prevents a buffer overflow in the
2690 tokenizer with very long source lines.
2691
Barry Warsaw538561e2006-01-01 21:48:54 +00002692- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2693 immediately after creating the object, without any intervening
2694 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002695
Skip Montanaro05885812005-01-16 20:48:27 +00002696- The reconvert.quote function can now emit triple-quoted strings. The
2697 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002698
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002699- ``UserString.MutableString`` now supports negative indices in
2700 ``__setitem__`` and ``__delitem__``
2701
Greg Ward40407942005-03-05 02:53:17 +00002702- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2703 correctly.
2704
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002705- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2706 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2707 character even if the user has passed a size parameter to get a proper
2708 line ending. Remove the special handling of a "\r\n" that has been split
2709 between two lines.
2710
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002711- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2712 about illegal code points. The codec now supports PEP 293 style error
2713 handlers.
2714
Walter Dörwald78a78b02005-09-01 12:04:29 +00002715- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002716 from the input stream, so that the output is a byte string in the correct
2717 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002718
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002719- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2720 considering it exactly like a '*'.
2721
Walter Dörwald007f8df2005-10-09 19:42:27 +00002722- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2723 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002724
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002725- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2726
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002727- Patch #1413711: Certain patterns of differences were making difflib
2728 touch the recursion limit.
2729
Walter Dörwald58917a62006-03-31 15:26:22 +00002730- Bug #947906: An object oriented interface has been added to the calendar
2731 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002732 called as a script (e.g. via ``python -mcalendar``). Localized month and
2733 weekday names can be ouput (even if an exotic encoding is used) using
2734 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002735
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002736Build
2737-----
2738
Neal Norwitz602d3392006-03-31 08:21:40 +00002739- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2740 by using -mieee gcc option.
2741
Martin v. Löwis86d66262006-02-17 08:40:11 +00002742- Patch #1432345: Make python compile on DragonFly.
2743
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002744- Build support for Win64-AMD64 was added.
2745
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002746- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2747
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002748- Patch #881820: look for openpty and forkpty also in libbsd.
2749
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002750- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2751 The zlib module is now builtin on Windows.
2752
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002753- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2754
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002755- Bug #1189330: configure did not correctly determine the necessary
2756 value of LINKCC if python was built with GCC 4.0.
2757
Trent Mick8321b422005-07-26 02:29:21 +00002758- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2759 vulnerability in zlib 1.2.1 and 1.2.2.
2760
Brett Cannon08cd5982005-04-24 22:26:38 +00002761- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2762 flags that change binary compatibility. Changes were also made to
2763 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002764 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002765
Bob Ippolitoed233462005-03-29 13:47:59 +00002766- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2767 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2768 no longer exists). This configure patch makes things right.
2769
Martin v. Löwise2713be2005-03-08 15:03:08 +00002770- Bug #1158607: Build with --disable-unicode again.
2771
Brett Cannon46d96232005-02-16 00:07:19 +00002772- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2773 defined. Discovered as a result of not being able to build on OS X.
2774
Brett Cannon516592f2004-12-07 00:42:59 +00002775- setup.py now uses the directories specified in LDFLAGS using the -L option
2776 and in CPPFLAGS using the -I option for adding library and include
2777 directories, respectively, for compiling extension modules against. This has
2778 led to the core being compiled using the values in CPPFLAGS. It also removes
2779 the need for the special-casing of both DarwinPorts and Fink for darwin since
2780 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2781 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2782 Fink, ``-I/opt/local/include`` for DarwinPorts).
2783
Brett Cannon43802422005-02-10 20:48:03 +00002784- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2785 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2786 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2787 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002789C API
2790-----
2791
Tim Petersc9d78aa2006-03-26 23:27:58 +00002792- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2793 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2794 is obtained via the ``PyObject_`` family, it must be released via the
2795 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2796 always been officially true, but when Python's small-object allocator was
2797 introduced, an attempt was made to cater to a few extension modules
2798 discovered at the time that obtained memory via ``PyObject_New`` but
2799 released it via ``PyMem_DEL``. It's years later, and if such code still
2800 exists it will fail now (probably with segfaults, but calling wrong
2801 low-level memory management functions can yield many symptoms).
2802
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002803- Added a C API for set and frozenset objects.
2804
Raymond Hettinger66517482004-12-03 11:45:13 +00002805- Removed PyRange_New().
2806
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002807- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2808 mapping argument now. This string is used as a mapping table. Byte values
2809 greater than the length of the string and 0xFFFE are treated as undefined
2810 mappings.
