597-----------------
598
Neal Norwitz0bcafac2006-09-11 08:51:17 +0000599- Make _PyGILState_NoteThreadState() static, it was not used anywhere
600 outside of pystate.c and should not be necessary.
601
Brett Cannon19d76c52006-09-09 07:18:44 +0000602- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
603 allows calling unicode() on exceptions classes directly to succeed.
604
Georg Brandlecab6232006-09-06 06:47:02 +0000605- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
606 Also make sure that every exception class has __module__ set to
607 'exceptions'.
608
Georg Brandl37a9e572006-09-06 06:09:34 +0000609- Bug #1550983: emit better error messages for erroneous relative

611
Tim Peterscbdd3502006-09-05 01:47:53 +0000612- Overflow checking code in integer division ran afoul of new gcc
613 optimizations. Changed to be more standard-conforming.

619
Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000620- The return tuple from str.rpartition(sep) is (tail, sep, head) where
621 head is the original string if sep was not found.
622
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000623- Bug #1520864: unpacking singleton tuples in list comprehensions and
624 generator expressions (x for x, in ... ) works again. Fixing this problem
625 required changing the .pyc magic number. This means that .pyc files
626 generated before 2.5c2 will be regenerated.

738Core and builtins
739-----------------
740
Neal Norwitz24b6f202006-09-05 04:43:56 +0000741- Fix infinite recursion when subclassing long and overriding __hash__.
742
743- Fix concatenation (+=) of long strings.
744
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000745- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000746 compared equal or unequal to a string and a UnicodeDecodeError
747 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000748
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000749 Instead, the equal (==) and unequal (!=) comparison operators will
750 now issue a UnicodeWarning and interpret the two objects as
751 unequal. The UnicodeWarning can be filtered as desired using
752 the warning framework, e.g. silenced completely, turned into an
753 exception, logged, etc.
754
755 Note that compare operators other than equal and unequal will still
756 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000757
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000758- Fix segfault when doing string formatting on subclasses of long.
759
760- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
761 with new-style classes.
762
763- Fix bug related to __len__ functions returning negative values with
764 classic classes.
765
766- Patch #1538606, Fix __index__() clipping. There were some problems
767 discovered with the API and how integers that didn't fit into Py_ssize_t
768 were handled. This patch attempts to provide enough alternatives
769 to effectively use __index__.
770
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000771- Bug #1536021: __hash__ may now return long int; the final hash
772 value is obtained by invoking hash on the long int.
773
Thomas Hellerab1049c2006-08-08 17:37:00 +0000774- Bug #1536786: buffer comparison could emit a RuntimeWarning.
775
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000776- Bug #1535165: fixed a segfault in input() and raw_input() when
777 sys.stdin is closed.
778
Thomas Heller74d36f02006-08-04 18:17:40 +0000779- On Windows, the PyErr_Warn function is now exported from
780 the Python dll again.
781
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000782- Bug #1191458: tracing over for loops now produces a line event
783 on each iteration. Fixing this problem required changing the .pyc
784 magic number. This means that .pyc files generated before 2.5c1
785 will be regenerated.
786
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000787- Bug #1333982: string/number constants were inappropriately stored
788 in the byte code and co_consts even if they were not used, ie
789 immediately popped off the stack.
790
Georg Brandle9462c72006-08-04 18:03:37 +0000791- Fixed a reference-counting problem in property().

794Library
795-------
796
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000797- Fix a bug in the ``compiler`` package that caused invalid code to be
798 generated for generator expressions.
799
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000800- The distutils version has been changed to 2.5.0. The change to
801 keep it programmatically in sync with the Python version running
802 the code (introduced in 2.5b3) has been reverted. It will continue
803 to be maintained manually as static string literal.
804
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000805- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000806 and this cannot be converted to the required C type, an exception is
807 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000808 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000809
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000810- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000811 an exception.
812
Tim Peterscbdd3502006-09-05 01:47:53 +0000813- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000814 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000815 workarounds for clocks with low resolution, to stop the code yielding
816 duplicate UUIDs.
817
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000818- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
819 before raising SystemExit, allowing IDLE to honor quit() and exit().
820
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000821- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
822
Georg Brandl7a1af772006-08-14 21:55:28 +0000823- Patch #1536071: trace.py should now find the full module name of a
824 file correctly even on Windows.
825
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000826- logging's atexit hook now runs even if the rest of the module has
827 already been cleaned up.
828
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000829- Bug #1112549, fix DoS attack on cgi.FieldStorage.

Neal Norwitzff4b63b2006-08-04 04:50:21 +0000831- Bug #1531405, format_exception no longer raises an exception if
832 str(exception) raised an exception.
833
Neil Schemenauer06ded092006-08-04 16:20:30 +0000834- Fix a bug in the ``compiler`` package that caused invalid code to be
835 generated for nested functions.

850
Thomas Heller86720042006-08-14 11:17:48 +0000851- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
852 uses the _as_parameter_ attribute when objects are passed to foreign
853 function calls. The ctypes version number was changed to 1.0.1.
854
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000855- Bug #1530559, struct.pack raises TypeError where it used to convert.
856 Passing float arguments to struct.pack when integers are expected
857 now triggers a DeprecationWarning.
858
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000859

898 the documentation was changed to state that the return value
899 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +0000902What's New in Python 2.5 beta 3?
903================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000904
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000905*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000906
907Core and builtins
908-----------------
909
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000910- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000911 returned a long (see PEP 353).
912
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000913- Bug #1515471: string.replace() accepts character buffers again.
914
Neal Norwitz07aadb12006-07-30 06:55:48 +0000915- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
916 This provides the proper warning for struct.pack().
917 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
918
Neal Norwitz0d62a062006-07-30 06:53:31 +0000919- Patch #1531113: Fix augmented assignment with yield expressions.
920 Also fix a SystemError when trying to assign to yield expressions.
921
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000922- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
923 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
924 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
925 excessive filesystem operations during imports.
926
Tim Petersbc24eee2006-07-27 01:14:53 +0000927- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
928 operations on signed longs that are formally undefined by C.
929 Unfortunately, at least one compiler now cares about that, so complicated
930 the code to make that compiler happy again.
931
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000932- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
933
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000934- Patch #1232023: Stop including current directory in search
935 path on Windows.
936
Neal Norwitze1fdb322006-07-21 05:32:28 +0000937- Fix some potential crashes found with failmalloc.
938
Neal Norwitze7563102006-07-17 01:00:16 +0000939- Fix warnings reported by Klocwork's static analysis tool.
940
Neal Norwitz84be93b2006-07-16 01:50:38 +0000941- Bug #1512814, Fix incorrect lineno's when code within a function
942 had more than 255 blank lines.
943
Georg Brandl9dceedb2006-07-12 15:31:17 +0000944- Patch #1521179: Python now accepts the standard options ``--help`` and
945 ``--version`` as well as ``/?`` on Windows.
946
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000947- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000948 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000949 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000950
Tim Peters112aad32006-07-19 00:03:19 +0000951- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000952 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000953 new ``sys._current_frames()`` returns a dictionary with one entry,
954 mapping the faux "thread id" 0 to the current frame.
955
Ronald Oussoren3075e162006-07-25 20:28:55 +0000956- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000957
Ronald Oussoren3075e162006-07-25 20:28:55 +0000958
Neal Norwitza1f10902006-07-12 07:28:29 +0000959Library
960-------
961
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000962- Correction of patch #1455898: In the mbcs decoder, set final=False
963 for stream decoder, but final=True for the decode function.
964
Georg Brandl07fec3a2006-08-01 18:49:24 +0000965- os.urandom no longer masks unrelated exceptions like SystemExit or
966 KeyboardInterrupt.
967
Tim Peters4643c2f2006-08-10 22:45:34 +0000968- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000969 shutil.copytree on Windows
970
Georg Brandle34ac7c2006-07-30 11:07:23 +0000971- Bug #1002398: The documentation for os.path.sameopenfile now correctly
972 refers to file descriptors, not file objects.
973
Tim Peterscbdd3502006-09-05 01:47:53 +0000974- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000975 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000976 #1513611, and probably others.
977
Georg Brandledd9b0d2006-07-29 09:33:26 +0000978- Bug #1441397: The compiler module now recognizes module and function
979 docstrings correctly as it did in Python 2.4.
980
Tim Peters6f681472006-07-27 23:44:37 +0000981- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
982 lost that tests are sorted by name before being run. This rarely
983 matters for well-written tests, but can create baffling symptoms if
984 side effects from one test to the next affect outcomes. ``DocTestFinder``
985 has been changed to sort the list of tests it returns.
986
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000987- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000988 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000989
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000990- Bug #978833: Really close underlying socket in _socketobject.close.
991
Georg Brandldb232dc2006-08-20 13:15:43 +0000992- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
993 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000994
Georg Brandlcf0c1722006-07-26 07:23:32 +0000995- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
996 to recursive calls and call it with the failing package name.
997
Martin v. Löwis0b483032006-07-25 09:53:12 +0000998- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
999
Georg Brandlc13c34c2006-07-24 14:09:56 +00001000- Patch #1515343: Fix printing of deprecated string exceptions with a
1001 value in the traceback module.
1002
Greg Ward48fae7a2006-07-23 16:05:51 +00001003- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1004
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001005- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1006
Brett Cannoncaebe222006-07-18 04:41:36 +00001007- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1008 argument tuple. For arguments where zero is illegal, the value is forced to
1009 the minimum value that is correct. This is to support an undocumented but
1010 common way people used to fill in inconsequential information in the time
1011 tuple pre-2.4.
1012
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001013- Patch #1220874: Update the binhex module for Mach-O.
1014
Barry Warsawb110bad2006-07-21 14:51:07 +00001015- The email package has improved RFC 2231 support, specifically for
1016 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1017 (name*0=<blah>) parameter continuations. This may change the types of
1018 values returned from email.message.Message.get_param() and friends.
1019 Specifically in some cases where non-encoded continuations were used,
1020 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1021 will just return the string (since non-encoded continuations don't have
1022 charset and language parts).
1023
1024 Also, whereas % values were decoded in all parameter continuations, they are
1025 now only decoded in encoded parameter parts.
1026
Ronald Oussoren3075e162006-07-25 20:28:55 +00001027- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1028
1029- Bug #1517996: IDLE now longer shows the default Tk menu when a
1030 path browser, class browser or debugger is the frontmost window on MacOS X
1031
Barry Warsaw00decd72006-07-27 23:43:15 +00001032- Patch #1520294: Support for getset and member descriptors in types.py,
1033 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1034 of an object against these built-in types and more importantly, for getting
1035 their docstrings printed in the interactive interpreter's help() function.
1036
Ronald Oussoren3075e162006-07-25 20:28:55 +00001037
Neal Norwitza1f10902006-07-12 07:28:29 +00001038Extension Modules
1039-----------------
1040
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001041- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1042 a socket operation on a socket with a timeout, the exception will be
1043 caught correctly. Previously, the exception was not caught.
1044
Thomas Heller1393d6a2006-07-28 21:43:20 +00001045- Patch #1529514: The _ctypes extension is now compiled on more
1046 openbsd target platforms.
1047
Tim Peters9cab5932006-07-28 00:30:00 +00001048- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1049 a memory leak, affecting pickles and deep copies.
1050
Tim Petersbc24eee2006-07-27 01:14:53 +00001051- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001052 Paul Eggert.
1053
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001054- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1055
Thomas Hellerce049a02006-07-14 17:51:14 +00001056- Patch #1521817: Index range checking on ctypes arrays containing
1057 exactly one element enabled again. This allows iterating over these
1058 arrays, without the need to check the array size before.
1059
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001060- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001061 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001062 /dev/null in certain cases; this is now fixed.
1063
Thomas Heller47d7a062006-07-12 08:43:47 +00001064- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1065 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001066
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001067- Because of a misspelled preprocessor symbol, ctypes was always
1068 compiled without thread support; this is now fixed.
1069
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001070- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1071 methods now allow their database parameter to be None as the
1072 sleepycat API allows.
1073
Matt Flemingec926502006-07-28 11:27:27 +00001074- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1075 bluetooth API compared with Linux and FreeBSD.
1076
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001077Tests
1078-----
1079
1080- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1081 how long the test file should take to play. Now accepts taking 2.93 secs
1082 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1083
Georg Brandl4793aa32006-07-28 18:31:39 +00001084- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1085 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1086 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001093Mac
1094---
1095
1096- PythonLauncher now works correctly when the path to the script contains
1097 characters that are treated specially by the shell (such as quotes).
1098
1099- Bug #1527397: PythonLauncher now launches scripts with the working directory
1100 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001101 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001102 expect.

1111-----------------
1112
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001113- Bug #1441486: The literal representation of -(sys.maxint - 1)
1114 again evaluates to a int object, not a long.
1115
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001116- Bug #1501934: The scope of global variables that are locally assigned
1117 using augmented assignment is now correctly determined.
1118
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001119- Bug #927248: Recursive method-wrapper objects can now safely
1120 be released.
1121
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001122- Bug #1417699: Reject locale-specific decimal point in float()
1123 and atof().
1124
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001125- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1126 omit a default "error" argument for NULL pointer. This allows
1127 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001128
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001129- Bug #1519018: 'as' is now validated properly in import statements.
1130
Neal Norwitz28746ab2006-07-09 22:14:42 +00001131- On 64 bit systems, int literals that use less than 64 bits are
1132 now ints rather than longs.
1133
Neal Norwitzed657552006-07-10 00:04:44 +00001134- Bug #1512814, Fix incorrect lineno's when code at module scope
1135 started after line 256.
1136
Tim Peters32a83612006-07-10 21:08:24 +00001137- New function ``sys._current_frames()`` returns a dict mapping thread
1138 id to topmost thread stack frame. This is for expert use, and is
1139 especially useful for debugging application deadlocks. The functionality
1140 was previously available in Fazal Majid's ``threadframe`` extension
1141 module, but it wasn't possible to do this in a wholly threadsafe way from
1142 an extension.

Martin v. Löwis77621582006-07-30 13:27:31 +00001147- Bug #1257728: Mention Cygwin in distutils error message about a missing
1148 VS 2003.
1149
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001150- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1151
Tim Peters32a83612006-07-10 21:08:24 +00001152- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001153 environment variable to be set in order to the SDK environment
1154 for finding the compiler, include files, etc.

Nick Coghlan2d792252006-07-06 13:47:18 +00001158- warnings.py now ignores ImportWarning by default
1159
Thomas Woutersadd19112006-07-05 11:03:49 +00001160- string.Template() now correctly handles tuple-values. Previously,
1161 multi-value tuples would raise an exception and single-value tuples would
1162 be treated as the value they contain, instead.
1163
Martin v. Löwisede77f52006-07-03 13:01:35 +00001164- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1165 even if some data are received.
1166
Martin v. Löwis45482392006-07-03 12:28:58 +00001167- Bug #1267547: Put proper recursive setup.py call into the
1168 spec file generated by bdist_rpm.
1169
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001170- Bug #1514693: Update turtle's heading when switching between
1171 degrees and radians.
1172
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001173- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001174 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001175
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001176- Bug #1514703: Only setup canvas window in turtle when the canvas
1177 is created.
1178
Martin v. Löwis7596e832006-07-01 15:33:37 +00001179- Bug #1513223: .close() of a _socketobj now releases the underlying
1180 socket again, which then gets closed as it becomes unreferenced.
1181
Fred Drake10497c82006-06-29 02:57:48 +00001182- Bug #1504333: Make sgmllib support angle brackets in quoted
1183 attribute values.
1184
1185- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1186 sgmllib ('[' and ']' were not accepted).
1187
Georg Brandl1be63af2006-06-28 20:23:25 +00001188- Fix a bug in the turtle module's end_fill function.
1189
Brett Cannon53ab5b72006-06-22 16:49:14 +00001190- Bug #1510580: The 'warnings' module improperly required that a Warning
1191 category be either a types.ClassType and a subclass of Warning. The proper
1192 check is just that it is a subclass with Warning as the documentation states.
1193
Georg Brandlad29e632006-06-21 17:45:17 +00001194- The compiler module now correctly compiles the new try-except-finally
1195 statement (bug #1509132).
1196
Neal Norwitz60373cd2006-06-22 06:30:50 +00001197- The wsgiref package is now installed properly on Unix.
1198
Vinay Sajip28e57612006-07-01 10:45:20 +00001199- A bug was fixed in logging.config.fileConfig() which caused a crash on
1200 shutdown when fileConfig() was called multiple times.
1201
Gerhard Häring762fbd32006-07-02 17:48:30 +00001202- The sqlite3 module did cut off data from the SQLite database at the first
1203 null character before sending it to a custom converter. This has been fixed
1204 now.
1205
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001206Extension Modules
1207-----------------
1208
Tim Peters112aad32006-07-19 00:03:19 +00001209- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1210 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1211 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001212
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001213- Assigning None to pointer type fields in ctypes structures possible
1214 overwrote the wrong fields, this is fixed now.
1215
1216- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1217 on non-Windows platforms.
1218
1219- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1220 integer or long, without range checking.
1221
1222- Patch #1517790: It is now possible to use custom objects in the ctypes
1223 foreign function argtypes sequence as long as they provide a from_param
1224 method, no longer is it required that the object is a ctypes type.
1225
1226- The '_ctypes' extension module now works when Python is configured
1227 with the --without-threads option.
1228
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001229- Bug #1513646: os.access on Windows now correctly determines write
1230 access, again.
1231
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001232- Bug #1512695: cPickle.loads could crash if it was interrupted with
1233 a KeyboardInterrupt.
1234
Neal Norwitza12aa882006-07-06 06:45:08 +00001235- Bug #1296433: parsing XML with a non-default encoding and
1236 a CharacterDataHandler could crash the interpreter in pyexpat.
1237
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001238- Patch #1516912: improve Modules support for OpenVMS.

1244
Tim Peters32a83612006-07-10 21:08:24 +00001245- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001246 Previously, the slight difference could cause compilation errors of the
1247 'zlib' module on systems with more than one version of zlib.
1248
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001249- The MSI compileall step was fixed to also support a TARGETDIR
1250 with spaces in it.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001279
1280Core and builtins
1281-----------------
1282
Georg Brandla56b9152006-06-19 06:35:54 +00001283- Patch #1507676: Error messages returned by invalid abstract object operations
1284 (such as iterating over an integer) have been improved and now include the
1285 type of the offending object to help with debugging.
1286
Brett Cannonea3912b2006-06-13 21:46:41 +00001287- Bug #992017: A classic class that defined a __coerce__() method that returned
1288 its arguments swapped would infinitely recurse and segfault the interpreter.
1289
Neal Norwitz909eb122006-06-12 02:13:21 +00001290- Fix the socket tests so they can be run concurrently.
1291
Neal Norwitzb9845e72006-06-12 02:11:18 +00001292- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001293 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001294
Brett Cannon22565aa2006-06-09 22:31:23 +00001295- Bug #532646: object.__call__() will continue looking for the __call__
1296 attribute on objects until one without one is found. This leads to recursion
1297 when you take a class and set its __call__ attribute to an instance of the
1298 class. Originally fixed for classic classes, but this fix is for new-style.
1299 Removes the infinite_rec_3 crasher.
1300
Georg Brandl24250812006-06-09 18:45:48 +00001301- The string and unicode methods startswith() and endswith() now accept
1302 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1303
Brett Cannonde3b0522006-06-08 17:00:45 +00001304- Buffer objects, at the C level, never used the char buffer
1305 implementation even when the char buffer for the wrapped object was
1306 explicitly requested (originally returned the read or write buffer).
1307 Now a TypeError is raised if the char buffer is not present but is
1308 requested.
1309
Georg Brandlddbaa662006-06-04 21:56:52 +00001310- Patch #1346214: Statements like "if 0: suite" are now again optimized
1311 away like they were in Python 2.4.
1312
Georg Brandlb7c8f542006-05-27 12:30:25 +00001313- Builtin exceptions are now full-blown new-style classes instead of
1314 instances pretending to be classes, which speeds up exception handling
1315 by about 80% in comparison to 2.5a2.
1316
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001317- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1318 Unicode 4.1.
1319
Georg Brandlf4ef1162006-05-26 18:03:31 +00001320- Patch #921466: sys.path_importer_cache is now used to cache valid and
1321 invalid file paths for the built-in import machinery which leads to
1322 fewer open calls on startup.
1323
Tim Peters696cf432006-05-24 21:10:40 +00001324- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1325 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1326 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1327 the number of input digits (it was and remains linear-time for bases
1328 2, 4, 8, 16 and 32).
1329
Tim Petersb713ec22006-05-23 18:45:30 +00001330- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1331 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1332 an integer close to ``sys.maxint``. This was repaired by patch
1333 #1335972, which also gives a nice speedup.
1334
Richard Jonescebbefc2006-05-23 18:28:17 +00001335- Patch #1337051: reduced size of frame objects.
1336
1337- PyErr_NewException now accepts a tuple of base classes as its
1338 "base" parameter.
1339
Richard Jones7c88dcc2006-05-23 10:37:38 +00001340- Patch #876206: function call speedup by retaining allocated frame
1341 objects.
1342
Georg Brandl7b90e162006-05-18 07:01:27 +00001343- Bug #1462152: file() now checks more thoroughly for invalid mode
1344 strings and removes a possible "U" before passing the mode to the
1345 C library function.
1346
Neal Norwitz1004a532006-05-15 07:17:23 +00001347- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1348
Neal Norwitz373f0a72006-05-15 07:04:36 +00001349- Bug #1487966: Fix SystemError with conditional expression in assignment
1350
Martin v. Löwis879768d2006-05-11 13:28:43 +00001351- WindowsError now has two error code attributes: errno, which carries
1352 the error values from errno.h, and winerror, which carries the error
1353 values from winerror.h. Previous versions put the winerror.h values
1354 (from GetLastError()) into the errno attribute.
1355
Martin v. Löwis77736712006-05-04 05:51:03 +00001356- Patch #1475845: Raise IndentationError for unexpected indent.
1357
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001358- Patch #1479181: split open() and file() from being aliases for each other.
1359
Tim Peters44bd9862006-06-01 13:49:23 +00001360- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1361 methods were always silently ignored by dictionaries when comparing keys.
1362 They are now passed through (except when using the C API function
1363 ``PyDict_GetItem()``, whose semantics did not change).
1364
1365- Bug #1456209: In some obscure cases it was possible for a class with a
1366 custom ``__eq__()`` method to confuse dict internals when class instances
1367 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1368 No, you don't have any code that did this ;-)

1375- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1376
Brett Cannon6ee7d012006-06-08 16:23:04 +00001377- Change binascii.hexlify to accept a read-only buffer instead of only a char
1378 buffer and actually follow its documentation.
1379
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001380- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1381
Nick Coghlanc649ec52006-05-29 12:43:05 +00001382- Patch #1478788 (modified version): The functional extension module has
1383 been renamed to _functools and a functools Python wrapper module added.
1384 This provides a home for additional function related utilities that are
1385 not specifically about functional programming. See PEP 309.
1386
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001387- Patch #1493701: performance enhancements for struct module.

Georg Brandl8d3342b2006-05-16 07:38:27 +00001391- Patch #1435422: zlib's compress and decompress objects now have a
1392 copy() method.
1393
Andrew MacIntyre92913322006-06-13 15:04:24 +00001394- Patch #1454481: thread stack size is now tunable at runtime for thread
1395 enabled builds on Windows and systems with Posix threads support.
1396
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001397- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1398 (up to the system limit of 32K characters).
1399
1400- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1401 As a result, these functions now raise WindowsError instead of OSError.
1402
Tim Peters7a822da2006-05-25 21:50:17 +00001403- ``time.clock()`` on Win64 should use the high-performance Windows
1404 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1405 Windows platforms).
1406
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001407- Calling Tk_Init twice is refused if the first call failed as that
1408 may deadlock.
1409
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001410- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1411 accept it without potentially using an uninitialized pointer.
1412
1413- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1414 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1415 patch numbers 1494885 and 1494902]

Gregory P. Smith372b5832006-06-05 18:48:21 +00001420- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1421 parameter is supplied. [SF pybsddb bug #1477863]
1422
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001423- bsddb: the __len__ method of a DB object has been fixed to return correct
1424 results. It could previously incorrectly return 0 in some cases.
1425 Fixes SF bug 1493322 (pybsddb bug 1184012).
1426
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001427- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1428 aborts the db transaction safely when a modifier callback fails.
1429 Fixes SF python patch/bug #1408584.
1430
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001431- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001432 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001433 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1434 database calls that would previously deadlock. [SF python bug #775414]
1435
Vinay Sajip28e57612006-07-01 10:45:20 +00001436- Patch #1446489: add support for the ZIP64 extensions to zipfile.

1464 double-byte encodings.
1465
Tim Peters43898b42006-06-14 04:09:25 +00001466- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1467 guarantee that adjacent triples in the return list always describe
1468 non-adjacent blocks. Previously, a pair of matching blocks could end
1469 up being described by multiple adjacent triples that formed a partition
1470 of the matching pair.
1471
Greg Ward0e0c9f42006-06-11 16:24:11 +00001472- Bug #1498146: fix optparse to handle Unicode strings in option help,

Greg Wardd1c797e2006-06-11 14:42:41 +00001475- Bug #1366250: minor optparse documentation error.
1476
Greg Ward7f547402006-06-11 00:40:49 +00001477- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1478 clarify docs.
1479
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001480- The wsgiref package has been added to the standard library.
1481
Nick Coghlan676725d2006-06-08 13:54:49 +00001482- The functions update_wrapper() and wraps() have been added to the functools
1483 module. These make it easier to copy relevant metadata from the original
1484 function when writing wrapper functions.
1485
Tim Petersd6a9eef2006-06-05 01:48:21 +00001486- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1487 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001488
Martin v. Löwis3f767792006-06-04 19:36:28 +00001489- Patch #1359618: Speed up charmap encoder by using a trie structure
1490 for lookup.
1491
Tim Petersd609b1a2006-06-02 23:22:51 +00001492- The functions in the ``pprint`` module now sort dictionaries by key
1493 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1494 if and only if its display required more than one line, although that
1495 wasn't documented. The new behavior increases predictability; e.g.,
1496 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1497
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001498- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1499 (thanks for J. J. Lee).
1500
Georg Brandl2b330372006-05-28 20:23:12 +00001501- Patch #1496206: improve urllib2 handling of passwords with respect to
1502 default HTTP and HTTPS ports.
1503
George Yoshidaf3c65de2006-05-28 16:39:09 +00001504- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1505
Bob Ippolito7298f272006-05-23 18:43:47 +00001506- Patch #1281707: speed up gzip.readline.
1507
Georg Brandlb89316f2006-05-17 15:51:16 +00001508- Patch #1180296: Two new functions were added to the locale module:
1509 format_string() to get the effect of "format % items" but locale-aware,
1510 and currency() to format a monetary number with currency sign.
1511
Georg Brandle3a25832006-05-17 14:56:04 +00001512- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1513 and several features added, such as speed and geometry control.
1514
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001515- Patch #1488881: add support for external file objects in bz2 compressed
1516 tarfiles.
1517
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001518- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1519 stdout arguments, making it possible to redirect input and output
1520 for remote debugging.
1521
1522- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1523 a couple of issues, notably handling of long file names using the
1524 GNU LONGNAME extension.
1525
1526- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1527 new flag when ``name`` is already the name of an option flag.
1528
1529- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1530 package.
1531
1532- Patch #1472854: make the rlcompleter.Completer class usable on non-
1533 UNIX platforms.
1534
1535- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1536
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001537- Bug #1472827: correctly escape newlines and tabs in attribute values in
1538 the saxutils.XMLGenerator class.

1547
Martin v. Löwisa43190b2006-05-22 09:15:18 +00001548- Patch #1492356: Port to Windows CE.
1549
Neal Norwitz58e28882006-05-19 07:00:58 +00001550- Bug/Patch #1481770: Use .so extension for shared libraries on HP-UX for ia64.
1551
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001552- Patch #1471883: Add --enable-universalsdk.

1567
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001568What's New in Python 2.5 alpha 2?
1569=================================
1570
1571*Release date: 27-APR-2006*
1572
1573Core and builtins
1574-----------------
1575
Thomas Heller1b046642006-04-18 18:51:06 +00001576- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1577 by converting these apis from macros into exported functions again:
1578
1579 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1580 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1581 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1582 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1583 PyRun_String Py_CompileString
1584
Martin v. Löwis45294a92006-04-18 06:24:08 +00001585- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1586
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001587- All uses of PyStructSequence_InitType have been changed to initialize
1588 the type objects only once, even if the interpreter is initialized
1589 multiple times.
1590
Neal Norwitz61546162006-04-14 05:20:28 +00001591- Bug #1454485, array.array('u') could crash the interpreter. This was
1592 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1593 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1594
1595- Py_UNICODE is unsigned. It was always documented as unsigned, but
1596 due to a bug had a signed value in previous versions.
1597
Tim Peters3a5e8b12006-04-11 01:44:07 +00001598- Patch #837242: ``id()`` of any Python object always gives a positive
1599 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1600 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001601 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001602 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001603
Tim Peters3a5e8b12006-04-11 01:44:07 +00001604 def __hash__(self):
1605 return id(self) # WRONG
1606
1607 because a hash result must be a (short) Python int but it was always
1608 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001609 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001610 was always usable as a hash value before this patch. That's no longer
1611 necessarily so.
1612
1613- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001614 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001615 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001616 #1454844)
1617
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001618- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1619 involving generators that have paused outside of any ``try`` or ``with``
1620 blocks. (In 2.5a1, a paused generator that was part of a reference
1621 cycle could not be garbage collected, regardless of whether it was
1622 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001623
Anthony Baxter51bcb682006-04-05 14:51:42 +00001624Extension Modules
1625-----------------
1626
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001627- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1628 is a macro.
1629
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001630- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1631 fails with an error condition.
1632
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001633- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1634
1635- Bug #1117761: bsddb.*open() no longer raises an exception when using
1636 the cachesize parameter.
1637
1638- Bug #1149413: bsddb.*open() no longer raises an exception when using
1639 a temporary db (file=None) with the 'n' flag to truncate on open.
1640
1641- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1642 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001643
Armin Rigoa9017c32006-04-19 11:50:27 +00001644- Patch #1062014: AF_UNIX sockets under Linux have a special
1645 abstract namespace that is now fully supported.
1646

1648-------
1649
Peter Astrand7d1d4362006-07-14 14:04:45 +00001650- Bug #1223937: subprocess.CalledProcessError reports the exit status
1651 of the process using the returncode attribute, instead of
1652 abusing errno.
1653
Tim Peters711bf302006-04-25 03:31:36 +00001654- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1655 a doctest to be skipped (the code is not run, and the expected output
1656 or exception is ignored).
1657
Nick Coghlanda2268f2006-04-24 04:37:15 +00001658- Fixed contextlib.nested to cope with exceptions being raised and
1659 caught inside exit handlers.
1660
Greg Wardab05edc2006-04-23 03:47:58 +00001661- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1662 hex, octal, or binary; add ``append_const`` action; keep going if
1663 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1664 added ``epilog`` for better help generation).
1665
Tim Peters21fbd572006-04-21 21:18:10 +00001666- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1667 called from a thread spawned as a side effect of importing a module.
1668
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001669- The pydoc module now supports documenting packages contained in
1670 .zip or .egg files.
1671
1672- The pkgutil module now has several new utility functions, such
1673 as ``walk_packages()`` to support working with packages that are either
1674 in the filesystem or zip files.
1675
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001676- The mailbox module can now modify and delete messages from
1677 mailboxes, in addition to simply reading them. Thanks to Gregory
1678 K. Johnson for writing the code, and to the 2005 Google Summer of
1679 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001680
Tim Petersc7605f22006-04-17 21:12:33 +00001681- The ``__del__`` method of class ``local`` in module ``_threading_local``
1682 returned before accomplishing any of its intended cleanup.
1683
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001684- Patch #790710: Add breakpoint command lists in pdb.
1685
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001686- Patch #1063914: Add Tkinter.Misc.clipboard_get().

1689
Anthony Baxtere29002c2006-04-12 12:07:31 +00001690- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1691 Windows. Bug #1469163.
1692
Phillip J. Eby47032112006-04-11 01:07:43 +00001693- The warnings, linecache, inspect, traceback, site, and doctest modules
1694 were updated to work correctly with modules imported from zipfiles or
1695 via other PEP 302 __loader__ objects.
1696
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001697- Patch #1467770: Reduce usage of subprocess._active to processes which
1698 the application hasn't waited on.

1708-----
1709
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001710- The Makefile now has a reindent target, which runs reindent.py on
1711 the library.
1712
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001713- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis0f48d982006-04-14 14:34:26 +00001717- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1718 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001719 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001720 CXX from --with-cxx-main, see description in README.
1721
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001722- Patch #1429775: Link extension modules with the shared libpython.
1723
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001724- Fixed a libffi build problem on MIPS systems.
1725
Tim Peters8931ff12006-05-13 23:28:20 +00001726- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1727 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1728 and "%zu" for unsigned integers of type ``size_t``.
1729
Anthony Baxter51bcb682006-04-05 14:51:42 +00001730Tests
1731-----
1732
Nick Coghlanda2268f2006-04-24 04:37:15 +00001733- test_contextlib now checks contextlib.nested can cope with exceptions
1734 being raised and caught inside exit handlers.
1735
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001736- test_cmd_line now checks operation of the -m and -c command switches
1737
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001738- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1739 it separately and by hand. It also wasn't cleaning up its changes to
1740 the current Decimal context.
1741
Thomas Woutersabd08882006-04-26 15:53:30 +00001742- regrtest.py now has a -M option to run tests that test the new limits of
1743 containers, on 64-bit architectures. Running these tests is only sensible
1744 on 64-bit machines with more than two gigabytes of memory. The argument
1745 passed is the maximum amount of memory for the tests to use.

1755
Tim Petersb06d28c2006-05-12 01:57:59 +00001756- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1757
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001758- PEP 343: Added Context Types section to the library reference
1759 and attempted to bring other PEP 343 related documentation into
1760 line with the implementation and/or python-dev discussions.
1761
Tim Peters8dc73d22006-04-24 02:03:16 +00001762- Bug #1337990: clarified that ``doctest`` does not support examples

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001766What's New in Python 2.5 alpha 1?
1767=================================
1768
Anthony Baxterebed3f62006-04-03 15:03:44 +00001769*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001770
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001771Core and builtins
1772-----------------
1773
Nick Coghlan43832302006-04-23 17:04:07 +00001774- PEP 338: -m command line switch now delegates to runpy.run_module
1775 allowing it to support modules in packages and zipfiles
1776
Martin v. Löwisc661b882006-04-20 04:54:23 +00001777- On Windows, .DLL is not an accepted file name extension for
1778 extension modules anymore; extensions are only found if they
1779 end in .PYD.
1780
Martin v. Löwisea62d252006-04-03 10:56:49 +00001781- Bug #1421664: sys.stderr.encoding is now set to the same value as
1782 sys.stdout.encoding.
1783
Neal Norwitz92e212f2006-04-03 04:48:37 +00001784- __import__ accepts keyword arguments.
1785
Georg Brandlccadf842006-03-31 18:54:53 +00001786- Patch #1460496: round() now accepts keyword arguments.
1787
Anthony Baxter262c00a2006-03-30 10:53:17 +00001788- Fixed bug #1459029 - unicode reprs were double-escaped.
1789
Hye-Shik Changd478f342006-03-23 12:32:36 +00001790- Patch #1396919: The system scope threads are reenabled on FreeBSD
1791 5.4 and later versions.
1792
Neal Norwitze98ccf62006-03-23 05:39:47 +00001793- Bug #1115379: Compiling a Unicode string with an encoding declaration
1794 now gives a SyntaxError.
1795
Georg Brandlabd1ff82006-03-18 07:59:59 +00001796- Previously, Python code had no easy way to access the contents of a
1797 cell object. Now, a ``cell_contents`` attribute has been added
1798 (closes patch #1170323).
1799
Tim Peterscf79aac2006-03-16 01:14:46 +00001800- Patch #1123430: Python's small-object allocator now returns an arena to
1801 the system ``free()`` when all memory within an arena becomes unused
1802 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1803 freed. Some applications will see a drop in virtual memory size now,
1804 especially long-running applications that, from time to time, temporarily
1805 use a large number of small objects. Note that when Python returns an
1806 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001807 platform C library will in turn return that memory to the operating system.
1808 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001809 appears to be effective at least on Microsoft C and gcc-based systems.
1810 Thanks to Evan Jones for hard work and patience.
1811
Georg Brandl533ff6f2006-03-08 18:09:27 +00001812- Patch #1434038: property() now uses the getter's docstring if there is
1813 no "doc" argument given. This makes it possible to legitimately use
1814 property() as a decorator to produce a read-only property.
1815
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001816- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1817 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1818 of requiring an int or long in slicing and a few other contexts, enabling
1819 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1820
Neal Norwitz995acdf2006-03-07 05:01:00 +00001821- Fixed various bugs reported by Coverity's Prevent tool.
1822
Brett Cannonbf364092006-03-01 04:25:17 +00001823- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1824 new exception base class, BaseException, which has a new message attribute.
1825 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1826 Raising a string exception now raises a DeprecationWarning.
1827
Thomas Woutersfb609f42006-02-28 16:37:25 +00001828- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1829 explicitly relative, using 'from .module import name' to mean 'from the same
1830 package as this module is in. Imports without dots still default to the
1831 old relative-then-absolute, unless 'from __future__ import
1832 absolute_import' is used.
1833
Brett Cannona7446e32006-02-27 23:39:10 +00001834- Properly check if 'warnings' raises an exception (usually when a filter set
1835 to "error" is triggered) when raising a warning for raising string
1836 exceptions.
1837
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001838- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001839 The name was removed from Include/code.h.
1840
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001841- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001842
Guido van Rossum1968ad32006-02-25 22:38:04 +00001843- Patch 1433928:
1844 - The copy module now "copies" function objects (as atomic objects).
1845 - dict.__getitem__ now looks for a __missing__ hook before raising
1846 KeyError.
1847
Tim Peters84ef21c2006-02-28 20:39:06 +00001848- PEP 343: with statement implemented. Needs ``from __future__ import
1849 with_statement``. Use of 'with' as a variable will generate a warning.
1850 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001851 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001852 The following objects have __context__ methods:
1853 - The built-in file type.
1854 - The thread.LockType type.
1855 - The following types defined by the threading module:
1856 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1857 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001858
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001859- Fix the encodings package codec search function to only search
1860 inside its own package. Fixes problem reported in patch #1433198.
1861
1862 Note: Codec packages should implement and register their own
1863 codec search function. PEP 100 has the details.
1864
Tim Peters9ea89d22006-06-04 03:26:02 +00001865- PEP 353: Using ``Py_ssize_t`` as the index type.
1866
1867- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1868 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1869 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1870 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1871 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001872
Neal Norwitzfc76d632006-01-10 06:03:13 +00001873- Patch #1400181, fix unicode string formatting to not use the locale.
1874 This is how string objects work. u'%f' could use , instead of .
1875 for the decimal point. Now both strings and unicode always use periods.
1876
Neal Norwitz671b9e32006-01-09 07:07:12 +00001877- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1878 configure would break checking curses.h.
1879
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001880- Bug #959576: The pwd module is now builtin. This allows Python to be
1881 built on UNIX platforms without $HOME set.
1882
Neal Norwitzc10978f2005-12-19 06:07:16 +00001883- Bug #1072182, fix some potential problems if characters are signed.
1884
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001885- Bug #889500, fix line number on SyntaxWarning for global declarations.
1886
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001887- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1888
Neal Norwitze7214a12005-12-18 05:03:17 +00001889- Support for converting hex strings to floats no longer works.
1890 This was not portable. float('0x3') now raises a ValueError.
1891
Barry Warsaw2a38a862005-12-18 01:27:35 +00001892- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001893 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001894 is now displayed in interactive prompt banner.
1895
Georg Brandlfa166682005-12-17 21:45:17 +00001896- Implementation of PEP 341 - Unification of try/except and try/finally.
1897 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001898 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001899
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001900- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1901 now encodes backslash correctly.
1902
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001903- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1904
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001905- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001906 and long longs.
1907
Neal Norwitz67715f02005-11-09 06:59:35 +00001908- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001909 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001910 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001911
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001912- Replaced most Unicode charmap codecs with new ones using the
1913 new Unicode translate string feature in the builtin charmap
1914 codec; the codecs were created from the mapping tables available
1915 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1916 encodings now include a mapping for the Apple logo)
1917
Tim Peterse3547fd2005-12-16 23:13:57 +00001918- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001919
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001920- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001921
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001922- A new AST parser implementation was completed. The abstract
1923 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001924 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001925
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001926- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001927 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1928
Neal Norwitz708e51a2005-10-03 04:48:15 +00001929- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1930
Neal Norwitz11bd1192005-10-03 00:54:56 +00001931- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1932 Provide a warning when a directory is passed on the command line.
1933
Neal Norwitz40d37812005-10-02 01:48:49 +00001934- Fix segfault with invalid coding.
1935
1936- SF bug #772896: unknown encoding results in MemoryError.
1937
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001938- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001939 supported a __len__() method which evaluated to False when the iterator
1940 was empty.
1941
Guido van Rossum630db602005-09-20 18:49:54 +00001942- On 64-bit platforms, when __len__() returns a value that cannot be
1943 represented as a C int, raise OverflowError.
1944
Skip Montanarof8948ca2005-09-19 03:54:46 +00001945- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001946 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001947
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001948- SF bug #893549: parsing keyword arguments was broken with a few format
1949 codes.
1950
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001951- Changes donated by Elemental Security to make it work on AIX 5.3
1952 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1953 bug #105470: test_pwd fails on 64bit system (Opteron).
1954
Guido van Rossum539c6622005-09-14 17:49:54 +00001955- Changes donated by Elemental Security to make it work on HP-UX 11 on
1956 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1957
Georg Brandl4550b8d2005-08-26 06:43:52 +00001958- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001959 (fixes bug #1119418).
1960
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001961- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1962
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001963- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1964 exceptions that cause a function to exit.
1965
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001966- The implementation of set() and frozenset() was revised to use its
1967 own internal data structure. Memory consumption is reduced by 1/3
1968 and there are modest speed-ups as well. The API is unchanged.
1969
Tim Petersde7990b2005-07-17 23:45:23 +00001970- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1971
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001972- SF bug #1229429: PyObject_CallMethod failed to decrement some
1973 reference counts in some error exit cases.
1974
Tim Petersecc6e6a2005-07-10 22:30:55 +00001975- SF bug #1185883: Python's small-object memory allocator took over
1976 a block managed by the platform C library whenever a realloc specified
1977 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001978 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001979 portable way to copy data from the C-managed block into Python's
1980 small-object space without risking a memory fault. Python's small-object
1981 realloc now leaves such blocks under the control of the platform C
1982 realloc.
1983
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001984- SF bug #1232517: An overflow error was not detected properly when
1985 attempting to convert a large float to an int in os.utime().
1986
Raymond Hettinger3296e692005-06-29 23:29:56 +00001987- SF bug #1224347: hex longs now print with lowercase letters just
1988 like their int counterparts.
1989
Michael W. Hudson188d4362005-06-20 16:52:57 +00001990- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1991 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1992 interpreter states; back out that fix and do a better job (see
1993 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1994 for a longer write-up of the problem).
1995
Michael W. Hudsondf888462005-06-03 14:41:55 +00001996- SF patch #1180995: marshal now uses a binary format by default when
1997 serializing floats.
1998
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001999- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2000 the routines that promise to produce IEEE 754 binary representations
2001 of floats now simply copy bytes around.
2002
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002003- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2004 278.
2005
Brett Cannonc3647ac2005-04-26 03:45:26 +00002006- patch #1109424: int, long, float, complex, and unicode now check for the
2007 proper magic slot for type conversions when subclassed. Previously the
2008 magic slot was ignored during conversion. Semantics now match the way
2009 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002010 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002011 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002012 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002013
Barry Warsawc8d907c2005-04-19 23:43:40 +00002014- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2015 NULL, now raise an AttributeError when attempting to set or delete the
2016 attribute. Previously a TypeError was raised, but this was inconsistent
2017 with the equivalent pure-Python implementation.
2018
Michael W. Hudson774479c2005-04-18 08:46:17 +00002019- It is now safe to call PyGILState_Release() before
2020 PyEval_InitThreads() (note that if there is reason to believe there
2021 are multiple threads around you still must call PyEval_InitThreads()
2022 before using the Python API; this fix is for extension modules that
2023 have no way of knowing if Python is multi-threaded yet).
2024
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002025- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2026 disabled caused a crash.
2027
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002028- Bug #1165306: instancemethod_new allowed the creation of a method
2029 with im_class == im_self == NULL, which caused a crash when called.
2030
Tim Petersecc6e6a2005-07-10 22:30:55 +00002031- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002032 fixes the crash seen in bug #1165761
2033
Raymond Hettinger96229b12005-03-11 06:49:40 +00002034- Added two new builtins, any() and all().
2035
Brett Cannon409d8f22005-03-05 06:47:57 +00002036- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002037 (e.g., ``class C(): pass`` is no longer a syntax error).
2038 Patch #1176012 added support to the 'parser' module and 'compiler' package
2039 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002040
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002041- Patch #1115086: Support PY_LONGLONG in structmember.
2042
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002043- Bug #1155938: new style classes did not check that __init__() was
2044 returning None.
2045
Tim Petersecc6e6a2005-07-10 22:30:55 +00002046- Patch #802188: Report characters after line continuation character

Tim Petersf4e69282006-02-27 17:15:31 +00002076- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2077 current thread state when the auto-GIL-state machinery knows about
2078 it (since the thread state is being deleted, continuing to remember it
2079 can't help, but can hurt if another thread happens to get created with
2080 the same thread id).

2289
Anthony Baxterc51ee692006-04-01 00:57:31 +00002290- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002291 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002292 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002293 module will not be built.

2318
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002319- email 4.0 package now integrated. This is largely the same as the email 3.0
2320 package that was included in Python 2.3, except that PEP 8 module names are
2321 now used (e.g. mail.message instead of email.Message). The MIME classes
2322 have been moved to a subpackage (e.g. email.mime.text instead of
2323 email.MIMEText). The old names are still supported for now. Several
2324 deprecated Message methods have been removed and lots of bugs have been
2325 fixed. More details can be found in the email package documentation.

2328 (a subclass of tuple) that provides incremental decoders and encoders
2329 (a way to use stateful codecs without the stream API). Python functions
2330 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2331 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2332 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002333
Walter Dörwald067db482006-03-15 22:17:27 +00002334- Patch #1359365: Calling next() on a closed StringIO.String object raises
2335 a ValueError instead of a StopIteration now (like file and cString.String do).
2336 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2337 called before (like file and StringIO.StringIO do).

Tim Peterse3547fd2005-12-16 23:13:57 +00002411 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2412 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2413 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2414 Ronald L. Rivest offered this advice for Python:
2415
2416 "The consensus of researchers in this area (at least as
2417 expressed at the NIST Hash Function Workshop 10/31/05),
2418 is that SHA-256 is a good choice for the time being, but
2419 that research should continue, and other alternatives may
2420 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002421

Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00002577- Patch #1049151: xdrlib now unpacks booleans as True or False.
2578
Raymond Hettingerbab41432005-02-05 01:31:19 +00002579- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2580
Guido van Rossumd0641422005-02-03 15:01:24 +00002581- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2582 disables recursive traversal through instance attributes, which can
2583 be exploited in various ways.
2584
Tim Peterse3547fd2005-12-16 23:13:57 +00002585- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002586 flags on the HTTP listening socket.
2587
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002588- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2589 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2590
Fred Drakefbdeaad2006-07-29 16:56:15 +00002591- Patches #893642, #1039083: add allow_none, encoding arguments to
2592 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.

2597
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002598- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2599
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002600- Enhancements to the csv module:
2601
2602 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002603 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002604 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002605 + Dialect parameter parsing has been re-implemented to improve error
2606 reporting.
2607 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2608 dictates.
2609 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002610 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002611 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002612 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2613 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002614 + reader now allows \r characters to be quoted (previously it only allowed
2615 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002616 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002617 + Dialect classes passed to the module are no longer instantiated by
2618 the module before being parsed (the former validation scheme required
2619 this, but the mechanism was unreliable).
2620 + The dialect registry now contains instances of the internal
2621 C-coded dialect type, rather than references to python objects.
2622 + the internal c-coded dialect type is now immutable.
2623 + register_dialect now accepts the same keyword dialect specifications
2624 as the reader and writer, allowing the user to register dialects
2625 without first creating a dialect class.
2626 + a configurable limit to the size of parsed fields has been added -
2627 previously, an unmatched quote character could result in the entire
2628 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002629 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002630 the parser field size limit (returning the former limit). The initial
2631 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002632 + A line_num attribute has been added to the reader object, which tracks
2633 the number of lines read from the source iterator. This is not
2634 the same as the number of records returned, as records can span
2635 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002636 + reader and writer objects were not being registered with the cyclic-GC.
2637 This has been fixed.
2638
Brett Cannone6539c42005-01-08 02:43:53 +00002639- _DummyThread objects in the threading module now delete self.__block that is
2640 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2641 lock primitives tend to be limited in number and thus should not be wasted on
2642 a _DummyThread object. Fixes bug #1089632.
2643
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002644- The imghdr module now detects Exif files.
2645
Raymond Hettinger6065d322004-12-20 23:51:53 +00002646- StringIO.truncate() now correctly adjusts the size attribute.
2647 (Bug #951915).
2648
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002649- locale.py now uses an updated locale alias table (built using
2650 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2651 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002652 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002653
Raymond Hettinger3557f422004-12-07 12:02:02 +00002654- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2655
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002656- the pickle module no longer accepts the deprecated None option in the
2657 args tuple returned by __reduce__().
2658
Brett Cannon84667c02004-12-07 03:25:18 +00002659- optparse now optionally imports gettext. This allows its use in setup.py.
2660
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002661- the pickle module no longer uses the deprecated bin parameter.
2662
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002663- the shelve module no longer uses the deprecated binary parameter.
2664
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002665- the pstats module no longer uses the deprecated ignore() method.
2666
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002667- the filecmp module no longer uses the deprecated use_statcache argument.
2668
Raymond Hettinger664347b2004-12-04 21:21:53 +00002669- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2670 extended or overridden by subclasses. Formerly, the subclassed method would
2671 be ignored by the rest of the module. (Bug #1078905).
2672
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002673- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002674 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002675
Walter Dörwald36733692004-12-22 12:50:50 +00002676- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2677 once when a size argument is given. This prevents a buffer overflow in the
2678 tokenizer with very long source lines.
2679
Barry Warsaw538561e2006-01-01 21:48:54 +00002680- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2681 immediately after creating the object, without any intervening
2682 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002683
Skip Montanaro05885812005-01-16 20:48:27 +00002684- The reconvert.quote function can now emit triple-quoted strings. The
2685 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002686
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002687- ``UserString.MutableString`` now supports negative indices in
2688 ``__setitem__`` and ``__delitem__``
2689
Greg Ward40407942005-03-05 02:53:17 +00002690- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2691 correctly.
2692
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002693- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2694 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2695 character even if the user has passed a size parameter to get a proper
2696 line ending. Remove the special handling of a "\r\n" that has been split
2697 between two lines.
2698
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002699- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2700 about illegal code points. The codec now supports PEP 293 style error
2701 handlers.
2702
Walter Dörwald78a78b02005-09-01 12:04:29 +00002703- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002704 from the input stream, so that the output is a byte string in the correct
2705 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002706
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002707- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2708 considering it exactly like a '*'.
2709
Walter Dörwald007f8df2005-10-09 19:42:27 +00002710- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2711 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002712
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002713- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2714
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002715- Patch #1413711: Certain patterns of differences were making difflib
2716 touch the recursion limit.
2717
Walter Dörwald58917a62006-03-31 15:26:22 +00002718- Bug #947906: An object oriented interface has been added to the calendar
2719 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002720 called as a script (e.g. via ``python -mcalendar``). Localized month and
2721 weekday names can be ouput (even if an exotic encoding is used) using
2722 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002723
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002724Build
2725-----
2726
Neal Norwitz602d3392006-03-31 08:21:40 +00002727- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2728 by using -mieee gcc option.
2729

2731
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002732- Build support for Win64-AMD64 was added.
2733
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002734- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2735
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002736- Patch #881820: look for openpty and forkpty also in libbsd.
2737
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002738- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2739 The zlib module is now builtin on Windows.
2740
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002741- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2742
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002743- Bug #1189330: configure did not correctly determine the necessary
2744 value of LINKCC if python was built with GCC 4.0.
2745
Trent Mick8321b422005-07-26 02:29:21 +00002746- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2747 vulnerability in zlib 1.2.1 and 1.2.2.
2748
Brett Cannon08cd5982005-04-24 22:26:38 +00002749- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2750 flags that change binary compatibility. Changes were also made to
2751 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002752 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002753
Bob Ippolitoed233462005-03-29 13:47:59 +00002754- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2755 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2756 no longer exists). This configure patch makes things right.
2757
Martin v. Löwise2713be2005-03-08 15:03:08 +00002758- Bug #1158607: Build with --disable-unicode again.
2759
Brett Cannon46d96232005-02-16 00:07:19 +00002760- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2761 defined. Discovered as a result of not being able to build on OS X.
2762
Brett Cannon516592f2004-12-07 00:42:59 +00002763- setup.py now uses the directories specified in LDFLAGS using the -L option
2764 and in CPPFLAGS using the -I option for adding library and include
2765 directories, respectively, for compiling extension modules against. This has
2766 led to the core being compiled using the values in CPPFLAGS. It also removes
2767 the need for the special-casing of both DarwinPorts and Fink for darwin since
2768 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2769 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2770 Fink, ``-I/opt/local/include`` for DarwinPorts).
2771
Brett Cannon43802422005-02-10 20:48:03 +00002772- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2773 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2774 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2775 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002777C API
2778-----
2779
Tim Petersc9d78aa2006-03-26 23:27:58 +00002780- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2781 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2782 is obtained via the ``PyObject_`` family, it must be released via the
2783 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2784 always been officially true, but when Python's small-object allocator was
2785 introduced, an attempt was made to cater to a few extension modules
2786 discovered at the time that obtained memory via ``PyObject_New`` but
2787 released it via ``PyMem_DEL``. It's years later, and if such code still
2788 exists it will fail now (probably with segfaults, but calling wrong
2789 low-level memory management functions can yield many symptoms).
2790
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002791- Added a C API for set and frozenset objects.
2792
Raymond Hettinger66517482004-12-03 11:45:13 +00002793- Removed PyRange_New().
2794
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002795- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2796 mapping argument now. This string is used as a mapping table. Byte values
2797 greater than the length of the string and 0xFFFE are treated as undefined
2798 mappings.
