293 pydoc's help keywords.
294

296 the IndexError caused by passing in an invalid breakpoint number.
297
Collin Winter86d8d352007-03-10 03:31:44 +0000298- Bug #1531963: Make SocketServer.TCPServer's server_address always
299 be equal to calling getsockname() on the server's socket. Fixed by patch
300 #1545011.
301
Thomas Heller8bf469d2007-03-09 20:48:57 +0000302- Bug #1651235: When a tuple was passed to a ctypes function call,
303 Python would crash instead of raising an error.

311
Georg Brandld59ea472007-03-08 18:37:35 +0000312- unittest now verifies more of its assumptions. In particular, TestCase
313 and TestSuite subclasses (not instances) are no longer accepted in
314 TestSuite.addTest(). This should cause no incompatibility since it
315 never made sense with ordinary subclasses -- the failure just occurred
316 later, with a more cumbersome exception.

Andrew M. Kuchling830358a2006-11-17 16:16:28 +0000431- mailbox.py: Change MH.pack() to not lock individual message files; this

Georg Brandl1f215782006-09-24 10:36:08 +0000450- Make webbrowser.BackgroundBrowser usable in Windows (it wasn't because

669Core and builtins
670-----------------
671
Neal Norwitz24b6f202006-09-05 04:43:56 +0000672- Fix infinite recursion when subclassing long and overriding __hash__.
673
674- Fix concatenation (+=) of long strings.
675
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000676- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000677 compared equal or unequal to a string and a UnicodeDecodeError
678 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000679
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000680 Instead, the equal (==) and unequal (!=) comparison operators will
681 now issue a UnicodeWarning and interpret the two objects as
682 unequal. The UnicodeWarning can be filtered as desired using
683 the warning framework, e.g. silenced completely, turned into an
684 exception, logged, etc.
685
686 Note that compare operators other than equal and unequal will still
687 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000688
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000689- Fix segfault when doing string formatting on subclasses of long.
690
691- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
692 with new-style classes.
693
694- Fix bug related to __len__ functions returning negative values with
695 classic classes.
696
697- Patch #1538606, Fix __index__() clipping. There were some problems
698 discovered with the API and how integers that didn't fit into Py_ssize_t
699 were handled. This patch attempts to provide enough alternatives
700 to effectively use __index__.
701
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000702- Bug #1536021: __hash__ may now return long int; the final hash
703 value is obtained by invoking hash on the long int.
704
Thomas Hellerab1049c2006-08-08 17:37:00 +0000705- Bug #1536786: buffer comparison could emit a RuntimeWarning.
706
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000707- Bug #1535165: fixed a segfault in input() and raw_input() when
708 sys.stdin is closed.
709
Thomas Heller74d36f02006-08-04 18:17:40 +0000710- On Windows, the PyErr_Warn function is now exported from
711 the Python dll again.
712
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000713- Bug #1191458: tracing over for loops now produces a line event
714 on each iteration. Fixing this problem required changing the .pyc
715 magic number. This means that .pyc files generated before 2.5c1
716 will be regenerated.
717
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000718- Bug #1333982: string/number constants were inappropriately stored
719 in the byte code and co_consts even if they were not used, ie
720 immediately popped off the stack.
721
Georg Brandle9462c72006-08-04 18:03:37 +0000722- Fixed a reference-counting problem in property().

725Library
726-------
727
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000728- Fix a bug in the ``compiler`` package that caused invalid code to be
729 generated for generator expressions.
730
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000731- The distutils version has been changed to 2.5.0. The change to
732 keep it programmatically in sync with the Python version running
733 the code (introduced in 2.5b3) has been reverted. It will continue
734 to be maintained manually as static string literal.
735
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000736- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000737 and this cannot be converted to the required C type, an exception is
738 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000739 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000740
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000741- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000742 an exception.
743
Tim Peterscbdd3502006-09-05 01:47:53 +0000744- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000745 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000746 workarounds for clocks with low resolution, to stop the code yielding
747 duplicate UUIDs.
748
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000749- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
750 before raising SystemExit, allowing IDLE to honor quit() and exit().
751
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000752- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
753
Georg Brandl7a1af772006-08-14 21:55:28 +0000754- Patch #1536071: trace.py should now find the full module name of a
755 file correctly even on Windows.
756
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000757- logging's atexit hook now runs even if the rest of the module has
758 already been cleaned up.
759
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000760- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000761
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000762- Bug #1531405, format_exception no longer raises an exception if
763 str(exception) raised an exception.
764
Neil Schemenauer06ded092006-08-04 16:20:30 +0000765- Fix a bug in the ``compiler`` package that caused invalid code to be
766 generated for nested functions.

777 raises the correct exceptions.
778
Thomas Heller1ce433e2006-08-14 16:20:04 +0000779- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
780 '-no-stack-protector' compiler flag for OpenBSD has been removed.
781
Thomas Heller86720042006-08-14 11:17:48 +0000782- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
783 uses the _as_parameter_ attribute when objects are passed to foreign
784 function calls. The ctypes version number was changed to 1.0.1.
785
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000786- Bug #1530559, struct.pack raises TypeError where it used to convert.
787 Passing float arguments to struct.pack when integers are expected
788 now triggers a DeprecationWarning.
789

838Core and builtins
839-----------------
840
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000841- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000842 returned a long (see PEP 353).
843
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000844- Bug #1515471: string.replace() accepts character buffers again.
845
Neal Norwitz07aadb12006-07-30 06:55:48 +0000846- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
847 This provides the proper warning for struct.pack().
848 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
849
Neal Norwitz0d62a062006-07-30 06:53:31 +0000850- Patch #1531113: Fix augmented assignment with yield expressions.
851 Also fix a SystemError when trying to assign to yield expressions.
852
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000853- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
854 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
855 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
856 excessive filesystem operations during imports.
857
Tim Petersbc24eee2006-07-27 01:14:53 +0000858- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
859 operations on signed longs that are formally undefined by C.
860 Unfortunately, at least one compiler now cares about that, so complicated
861 the code to make that compiler happy again.
862
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000863- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
864
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000865- Patch #1232023: Stop including current directory in search
866 path on Windows.
867
Neal Norwitze1fdb322006-07-21 05:32:28 +0000868- Fix some potential crashes found with failmalloc.
869
Neal Norwitze7563102006-07-17 01:00:16 +0000870- Fix warnings reported by Klocwork's static analysis tool.
871
Neal Norwitz84be93b2006-07-16 01:50:38 +0000872- Bug #1512814, Fix incorrect lineno's when code within a function
873 had more than 255 blank lines.
874
Georg Brandl9dceedb2006-07-12 15:31:17 +0000875- Patch #1521179: Python now accepts the standard options ``--help`` and
876 ``--version`` as well as ``/?`` on Windows.
877
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000878- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000879 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000880 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000881
Tim Peters112aad32006-07-19 00:03:19 +0000882- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000883 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000884 new ``sys._current_frames()`` returns a dictionary with one entry,
885 mapping the faux "thread id" 0 to the current frame.
886
Ronald Oussoren3075e162006-07-25 20:28:55 +0000887- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

Martin v. Löwis961b91b2006-08-02 13:53:55 +0000893- Correction of patch #1455898: In the mbcs decoder, set final=False
894 for stream decoder, but final=True for the decode function.
895
Georg Brandl07fec3a2006-08-01 18:49:24 +0000896- os.urandom no longer masks unrelated exceptions like SystemExit or
897 KeyboardInterrupt.
898
Tim Peters4643c2f2006-08-10 22:45:34 +0000899- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000900 shutil.copytree on Windows
901
Georg Brandle34ac7c2006-07-30 11:07:23 +0000902- Bug #1002398: The documentation for os.path.sameopenfile now correctly
903 refers to file descriptors, not file objects.
904
Tim Peterscbdd3502006-09-05 01:47:53 +0000905- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000906 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000907 #1513611, and probably others.
908
Georg Brandledd9b0d2006-07-29 09:33:26 +0000909- Bug #1441397: The compiler module now recognizes module and function
910 docstrings correctly as it did in Python 2.4.
911
Tim Peters6f681472006-07-27 23:44:37 +0000912- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
913 lost that tests are sorted by name before being run. This rarely
914 matters for well-written tests, but can create baffling symptoms if
915 side effects from one test to the next affect outcomes. ``DocTestFinder``
916 has been changed to sort the list of tests it returns.
917
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000918- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000919 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000920
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000921- Bug #978833: Really close underlying socket in _socketobject.close.
922
Georg Brandldb232dc2006-08-20 13:15:43 +0000923- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
924 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000925
Georg Brandlcf0c1722006-07-26 07:23:32 +0000926- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
927 to recursive calls and call it with the failing package name.
928
Martin v. Löwis0b483032006-07-25 09:53:12 +0000929- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
930
Georg Brandlc13c34c2006-07-24 14:09:56 +0000931- Patch #1515343: Fix printing of deprecated string exceptions with a
932 value in the traceback module.
933
Greg Ward48fae7a2006-07-23 16:05:51 +0000934- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
935
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000936- Patch #1524429: Use repr() instead of backticks in Tkinter again.
937
Brett Cannoncaebe222006-07-18 04:41:36 +0000938- Bug #1520914: Change time.strftime() to accept a zero for any position in its
939 argument tuple. For arguments where zero is illegal, the value is forced to
940 the minimum value that is correct. This is to support an undocumented but
941 common way people used to fill in inconsequential information in the time
942 tuple pre-2.4.
943
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000944- Patch #1220874: Update the binhex module for Mach-O.
945
Barry Warsawb110bad2006-07-21 14:51:07 +0000946- The email package has improved RFC 2231 support, specifically for
947 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
948 (name*0=<blah>) parameter continuations. This may change the types of
949 values returned from email.message.Message.get_param() and friends.
950 Specifically in some cases where non-encoded continuations were used,
951 get_param() used to return a 3-tuple of (None, None, string) whereas now it
952 will just return the string (since non-encoded continuations don't have
953 charset and language parts).
954
955 Also, whereas % values were decoded in all parameter continuations, they are
956 now only decoded in encoded parameter parts.
957
Ronald Oussoren3075e162006-07-25 20:28:55 +0000958- Bug #1517990: IDLE keybindings on MacOS X now work correctly
959
960- Bug #1517996: IDLE now longer shows the default Tk menu when a
961 path browser, class browser or debugger is the frontmost window on MacOS X
962
Barry Warsaw00decd72006-07-27 23:43:15 +0000963- Patch #1520294: Support for getset and member descriptors in types.py,
964 inspect.py, and pydoc.py. Specifically, this allows for querying the type
965 of an object against these built-in types and more importantly, for getting
966 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +0000969Extension Modules
970-----------------
971
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000972- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
973 a socket operation on a socket with a timeout, the exception will be
974 caught correctly. Previously, the exception was not caught.
975
Thomas Heller1393d6a2006-07-28 21:43:20 +0000976- Patch #1529514: The _ctypes extension is now compiled on more
977 openbsd target platforms.
978
Tim Peters9cab5932006-07-28 00:30:00 +0000979- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
980 a memory leak, affecting pickles and deep copies.
981
Tim Petersbc24eee2006-07-27 01:14:53 +0000982- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000983 Paul Eggert.
984
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000985- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
986
Thomas Hellerce049a02006-07-14 17:51:14 +0000987- Patch #1521817: Index range checking on ctypes arrays containing
988 exactly one element enabled again. This allows iterating over these
989 arrays, without the need to check the array size before.
990
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000991- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000992 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000993 /dev/null in certain cases; this is now fixed.
994
Thomas Heller47d7a062006-07-12 08:43:47 +0000995- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
996 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000997
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000998- Because of a misspelled preprocessor symbol, ctypes was always
999 compiled without thread support; this is now fixed.
1000
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001001- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1002 methods now allow their database parameter to be None as the
1003 sleepycat API allows.
1004
Matt Flemingec926502006-07-28 11:27:27 +00001005- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1006 bluetooth API compared with Linux and FreeBSD.
1007
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001008Tests
1009-----
1010
1011- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1012 how long the test file should take to play. Now accepts taking 2.93 secs
1013 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1014
Georg Brandl4793aa32006-07-28 18:31:39 +00001015- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1016 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1017 run via ``regrtest.py``. Now they do.

1022- Bug #1439538: Drop usage of test -e in configure as it is not portable.
1023
Ronald Oussoren26cad082006-08-01 21:00:57 +00001024Mac
1025---
1026
1027- PythonLauncher now works correctly when the path to the script contains
1028 characters that are treated specially by the shell (such as quotes).
1029
1030- Bug #1527397: PythonLauncher now launches scripts with the working directory
1031 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001032 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001033 expect.

1042-----------------
1043
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001044- Bug #1441486: The literal representation of -(sys.maxint - 1)
1045 again evaluates to a int object, not a long.
1046
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001047- Bug #1501934: The scope of global variables that are locally assigned
1048 using augmented assignment is now correctly determined.
1049
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001050- Bug #927248: Recursive method-wrapper objects can now safely
1051 be released.
1052
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001053- Bug #1417699: Reject locale-specific decimal point in float()
1054 and atof().
1055
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001056- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1057 omit a default "error" argument for NULL pointer. This allows
1058 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001059
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001060- Bug #1519018: 'as' is now validated properly in import statements.
1061
Neal Norwitz28746ab2006-07-09 22:14:42 +00001062- On 64 bit systems, int literals that use less than 64 bits are
1063 now ints rather than longs.
1064
Neal Norwitzed657552006-07-10 00:04:44 +00001065- Bug #1512814, Fix incorrect lineno's when code at module scope
1066 started after line 256.
1067
Tim Peters32a83612006-07-10 21:08:24 +00001068- New function ``sys._current_frames()`` returns a dict mapping thread
1069 id to topmost thread stack frame. This is for expert use, and is
1070 especially useful for debugging application deadlocks. The functionality
1071 was previously available in Fazal Majid's ``threadframe`` extension
1072 module, but it wasn't possible to do this in a wholly threadsafe way from
1073 an extension.

1082
Tim Peters32a83612006-07-10 21:08:24 +00001083- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001084 environment variable to be set in order to the SDK environment
1085 for finding the compiler, include files, etc.

1090
Thomas Woutersadd19112006-07-05 11:03:49 +00001091- string.Template() now correctly handles tuple-values. Previously,
1092 multi-value tuples would raise an exception and single-value tuples would
1093 be treated as the value they contain, instead.
1094
Martin v. Löwisede77f52006-07-03 13:01:35 +00001095- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1097
Martin v. Löwis45482392006-07-03 12:28:58 +00001098- Bug #1267547: Put proper recursive setup.py call into the

1102 degrees and radians.
1103
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001104- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001105 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001106
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001107- Bug #1514703: Only setup canvas window in turtle when the canvas
1108 is created.
1109
Martin v. Löwis7596e832006-07-01 15:33:37 +00001110- Bug #1513223: .close() of a _socketobj now releases the underlying
1111 socket again, which then gets closed as it becomes unreferenced.
1112
Fred Drake10497c82006-06-29 02:57:48 +00001113- Bug #1504333: Make sgmllib support angle brackets in quoted
1114 attribute values.
1115
1116- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1117 sgmllib ('[' and ']' were not accepted).
1118
Georg Brandl1be63af2006-06-28 20:23:25 +00001119- Fix a bug in the turtle module's end_fill function.
1120
Brett Cannon53ab5b72006-06-22 16:49:14 +00001121- Bug #1510580: The 'warnings' module improperly required that a Warning
1122 category be either a types.ClassType and a subclass of Warning. The proper
1123 check is just that it is a subclass with Warning as the documentation states.
1124
Georg Brandlad29e632006-06-21 17:45:17 +00001125- The compiler module now correctly compiles the new try-except-finally
1126 statement (bug #1509132).
1127
Neal Norwitz60373cd2006-06-22 06:30:50 +00001128- The wsgiref package is now installed properly on Unix.
1129
Vinay Sajip28e57612006-07-01 10:45:20 +00001130- A bug was fixed in logging.config.fileConfig() which caused a crash on
1131 shutdown when fileConfig() was called multiple times.
1132
Gerhard Häring762fbd32006-07-02 17:48:30 +00001133- The sqlite3 module did cut off data from the SQLite database at the first
1134 null character before sending it to a custom converter. This has been fixed
1135 now.
1136
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001137Extension Modules
1138-----------------
1139
Tim Peters112aad32006-07-19 00:03:19 +00001140- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1141 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1142 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001143
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001144- Assigning None to pointer type fields in ctypes structures possible
1145 overwrote the wrong fields, this is fixed now.
1146
1147- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1148 on non-Windows platforms.
1149
1150- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1151 integer or long, without range checking.
1152
1153- Patch #1517790: It is now possible to use custom objects in the ctypes
1154 foreign function argtypes sequence as long as they provide a from_param
1155 method, no longer is it required that the object is a ctypes type.
1156
1157- The '_ctypes' extension module now works when Python is configured
1158 with the --without-threads option.
1159
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001160- Bug #1513646: os.access on Windows now correctly determines write

1162
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001163- Bug #1512695: cPickle.loads could crash if it was interrupted with
1164 a KeyboardInterrupt.

1175
Tim Peters32a83612006-07-10 21:08:24 +00001176- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001177 Previously, the slight difference could cause compilation errors of the
1178 'zlib' module on systems with more than one version of zlib.
1179
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001180- The MSI compileall step was fixed to also support a TARGETDIR
1181 with spaces in it.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001210
1211Core and builtins
1212-----------------
1213
Georg Brandla56b9152006-06-19 06:35:54 +00001214- Patch #1507676: Error messages returned by invalid abstract object operations
1215 (such as iterating over an integer) have been improved and now include the
1216 type of the offending object to help with debugging.
1217
Brett Cannonea3912b2006-06-13 21:46:41 +00001218- Bug #992017: A classic class that defined a __coerce__() method that returned
1219 its arguments swapped would infinitely recurse and segfault the interpreter.
1220
Neal Norwitz909eb122006-06-12 02:13:21 +00001221- Fix the socket tests so they can be run concurrently.
1222
Neal Norwitzb9845e72006-06-12 02:11:18 +00001223- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001224 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001225
Brett Cannon22565aa2006-06-09 22:31:23 +00001226- Bug #532646: object.__call__() will continue looking for the __call__
1227 attribute on objects until one without one is found. This leads to recursion
1228 when you take a class and set its __call__ attribute to an instance of the
1229 class. Originally fixed for classic classes, but this fix is for new-style.
1230 Removes the infinite_rec_3 crasher.
1231
Georg Brandl24250812006-06-09 18:45:48 +00001232- The string and unicode methods startswith() and endswith() now accept
1233 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1234
Brett Cannonde3b0522006-06-08 17:00:45 +00001235- Buffer objects, at the C level, never used the char buffer
1236 implementation even when the char buffer for the wrapped object was
1237 explicitly requested (originally returned the read or write buffer).
1238 Now a TypeError is raised if the char buffer is not present but is
1239 requested.
1240
Georg Brandlddbaa662006-06-04 21:56:52 +00001241- Patch #1346214: Statements like "if 0: suite" are now again optimized
1242 away like they were in Python 2.4.
1243
Georg Brandlb7c8f542006-05-27 12:30:25 +00001244- Builtin exceptions are now full-blown new-style classes instead of
1245 instances pretending to be classes, which speeds up exception handling
1246 by about 80% in comparison to 2.5a2.
1247
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001248- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1249 Unicode 4.1.
1250
Georg Brandlf4ef1162006-05-26 18:03:31 +00001251- Patch #921466: sys.path_importer_cache is now used to cache valid and
1252 invalid file paths for the built-in import machinery which leads to
1253 fewer open calls on startup.
1254
Tim Peters696cf432006-05-24 21:10:40 +00001255- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1256 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1257 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1258 the number of input digits (it was and remains linear-time for bases
1259 2, 4, 8, 16 and 32).
1260
Tim Petersb713ec22006-05-23 18:45:30 +00001261- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1262 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1263 an integer close to ``sys.maxint``. This was repaired by patch
1264 #1335972, which also gives a nice speedup.
1265
Richard Jonescebbefc2006-05-23 18:28:17 +00001266- Patch #1337051: reduced size of frame objects.
1267
1268- PyErr_NewException now accepts a tuple of base classes as its
1269 "base" parameter.
1270
Richard Jones7c88dcc2006-05-23 10:37:38 +00001271- Patch #876206: function call speedup by retaining allocated frame
1272 objects.
1273
Georg Brandl7b90e162006-05-18 07:01:27 +00001274- Bug #1462152: file() now checks more thoroughly for invalid mode
1275 strings and removes a possible "U" before passing the mode to the
1276 C library function.
1277
Neal Norwitz1004a532006-05-15 07:17:23 +00001278- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1279
Neal Norwitz373f0a72006-05-15 07:04:36 +00001280- Bug #1487966: Fix SystemError with conditional expression in assignment
1281
Martin v. Löwis879768d2006-05-11 13:28:43 +00001282- WindowsError now has two error code attributes: errno, which carries
1283 the error values from errno.h, and winerror, which carries the error
1284 values from winerror.h. Previous versions put the winerror.h values
1285 (from GetLastError()) into the errno attribute.
1286
Martin v. Löwis77736712006-05-04 05:51:03 +00001287- Patch #1475845: Raise IndentationError for unexpected indent.
1288
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001289- Patch #1479181: split open() and file() from being aliases for each other.
1290
Tim Peters44bd9862006-06-01 13:49:23 +00001291- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1292 methods were always silently ignored by dictionaries when comparing keys.
1293 They are now passed through (except when using the C API function
1294 ``PyDict_GetItem()``, whose semantics did not change).
1295
1296- Bug #1456209: In some obscure cases it was possible for a class with a
1297 custom ``__eq__()`` method to confuse dict internals when class instances
1298 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1299 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001301Extension Modules
1302-----------------
1303
Trent Mick960a3f82006-06-28 20:30:41 +00001304- Bug #1295808: expat symbols should be namespaced in pyexpat
1305
1306- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1307
Brett Cannon6ee7d012006-06-08 16:23:04 +00001308- Change binascii.hexlify to accept a read-only buffer instead of only a char
1309 buffer and actually follow its documentation.
1310
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001311- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1312
Nick Coghlanc649ec52006-05-29 12:43:05 +00001313- Patch #1478788 (modified version): The functional extension module has
1314 been renamed to _functools and a functools Python wrapper module added.
1315 This provides a home for additional function related utilities that are
1316 not specifically about functional programming. See PEP 309.
1317
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001318- Patch #1493701: performance enhancements for struct module.
1319
Georg Brandl378d5922006-05-17 14:26:50 +00001320- Patch #1490224: time.altzone is now set correctly on Cygwin.
1321
Georg Brandl8d3342b2006-05-16 07:38:27 +00001322- Patch #1435422: zlib's compress and decompress objects now have a
1323 copy() method.
1324
Andrew MacIntyre92913322006-06-13 15:04:24 +00001325- Patch #1454481: thread stack size is now tunable at runtime for thread
1326 enabled builds on Windows and systems with Posix threads support.
1327
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001328- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1329 (up to the system limit of 32K characters).
1330
1331- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1332 As a result, these functions now raise WindowsError instead of OSError.
1333
Tim Peters7a822da2006-05-25 21:50:17 +00001334- ``time.clock()`` on Win64 should use the high-performance Windows
1335 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1336 Windows platforms).
1337
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001338- Calling Tk_Init twice is refused if the first call failed as that
1339 may deadlock.
1340
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001341- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1342 accept it without potentially using an uninitialized pointer.
1343
1344- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1345 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1346 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001347
Gregory P. Smith372b5832006-06-05 18:48:21 +00001348- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001349 [pybsddb project SF patch number 1466734]
1350
Gregory P. Smith372b5832006-06-05 18:48:21 +00001351- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1352 parameter is supplied. [SF pybsddb bug #1477863]
1353
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001354- bsddb: the __len__ method of a DB object has been fixed to return correct
1355 results. It could previously incorrectly return 0 in some cases.
1356 Fixes SF bug 1493322 (pybsddb bug 1184012).
1357
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001358- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1359 aborts the db transaction safely when a modifier callback fails.
1360 Fixes SF python patch/bug #1408584.
1361
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001362- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001363 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001364 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1365 database calls that would previously deadlock. [SF python bug #775414]
1366
Vinay Sajip28e57612006-07-01 10:45:20 +00001367- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001368
Walter Dörwald4994d952006-06-19 08:07:50 +00001369- Patch #1506645: add Python wrappers for the curses functions
1370 is_term_resized, resize_term and resizeterm.

1373-------
1374
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001375- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1376 functions.
1377
Martin v. Löwis3798da02006-06-17 18:44:27 +00001378- Patch #812986: Update turtle output even if not tracing.
1379
Vinay Sajip28e57612006-07-01 10:45:20 +00001380- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001381 Tkinter.BaseWidget.
1382
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001383- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1384
Martin v. Löwis337487e2006-06-17 09:15:14 +00001385- Patch #763580: Add name and value arguments to Tkinter variable
1386 classes.
1387
Georg Brandl83cc0d02006-06-14 08:50:03 +00001388- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1389 mime.types file for determining MIME types.
1390
Georg Brandl2605ca82006-06-14 06:08:31 +00001391- Bug #1339007: Shelf objects now don't raise an exception in their
1392 __del__ method when initialization failed.
1393
Martin v. Löwisd8251432006-06-14 05:21:04 +00001394- Patch #1455898: The MBCS codec now supports the incremental mode for
1395 double-byte encodings.
1396
Tim Peters43898b42006-06-14 04:09:25 +00001397- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1398 guarantee that adjacent triples in the return list always describe
1399 non-adjacent blocks. Previously, a pair of matching blocks could end
1400 up being described by multiple adjacent triples that formed a partition
1401 of the matching pair.
1402
Greg Ward0e0c9f42006-06-11 16:24:11 +00001403- Bug #1498146: fix optparse to handle Unicode strings in option help,
1404 description, and epilog.
1405
Greg Wardd1c797e2006-06-11 14:42:41 +00001406- Bug #1366250: minor optparse documentation error.
1407
Greg Ward7f547402006-06-11 00:40:49 +00001408- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1409 clarify docs.
1410
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001411- The wsgiref package has been added to the standard library.
1412
Nick Coghlan676725d2006-06-08 13:54:49 +00001413- The functions update_wrapper() and wraps() have been added to the functools
1414 module. These make it easier to copy relevant metadata from the original
1415 function when writing wrapper functions.
1416
Tim Petersd6a9eef2006-06-05 01:48:21 +00001417- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1418 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001419
Martin v. Löwis3f767792006-06-04 19:36:28 +00001420- Patch #1359618: Speed up charmap encoder by using a trie structure
1421 for lookup.
1422
Tim Petersd609b1a2006-06-02 23:22:51 +00001423- The functions in the ``pprint`` module now sort dictionaries by key
1424 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1425 if and only if its display required more than one line, although that
1426 wasn't documented. The new behavior increases predictability; e.g.,
1427 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1428
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001429- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1430 (thanks for J. J. Lee).
1431
Georg Brandl2b330372006-05-28 20:23:12 +00001432- Patch #1496206: improve urllib2 handling of passwords with respect to
1433 default HTTP and HTTPS ports.
1434
George Yoshidaf3c65de2006-05-28 16:39:09 +00001435- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1436
Bob Ippolito7298f272006-05-23 18:43:47 +00001437- Patch #1281707: speed up gzip.readline.
1438
Georg Brandlb89316f2006-05-17 15:51:16 +00001439- Patch #1180296: Two new functions were added to the locale module:
1440 format_string() to get the effect of "format % items" but locale-aware,
1441 and currency() to format a monetary number with currency sign.
1442
Georg Brandle3a25832006-05-17 14:56:04 +00001443- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1444 and several features added, such as speed and geometry control.
1445
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001446- Patch #1488881: add support for external file objects in bz2 compressed
1447 tarfiles.
1448
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001449- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1450 stdout arguments, making it possible to redirect input and output
1451 for remote debugging.
1452
1453- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1454 a couple of issues, notably handling of long file names using the
1455 GNU LONGNAME extension.
1456
1457- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1458 new flag when ``name`` is already the name of an option flag.
1459
1460- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1461 package.
1462
1463- Patch #1472854: make the rlcompleter.Completer class usable on non-
1464 UNIX platforms.
1465
1466- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1467
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001468- Bug #1472827: correctly escape newlines and tabs in attribute values in
1469 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001499What's New in Python 2.5 alpha 2?
1500=================================
1501
1502*Release date: 27-APR-2006*
1503
1504Core and builtins
1505-----------------
1506
Thomas Heller1b046642006-04-18 18:51:06 +00001507- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1508 by converting these apis from macros into exported functions again:
1509
1510 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1511 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1512 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1513 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1514 PyRun_String Py_CompileString
1515
Martin v. Löwis45294a92006-04-18 06:24:08 +00001516- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1517
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001518- All uses of PyStructSequence_InitType have been changed to initialize
1519 the type objects only once, even if the interpreter is initialized
1520 multiple times.
1521
Neal Norwitz61546162006-04-14 05:20:28 +00001522- Bug #1454485, array.array('u') could crash the interpreter. This was
1523 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1524 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1525
1526- Py_UNICODE is unsigned. It was always documented as unsigned, but
1527 due to a bug had a signed value in previous versions.
1528
Tim Peters3a5e8b12006-04-11 01:44:07 +00001529- Patch #837242: ``id()`` of any Python object always gives a positive
1530 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1531 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001532 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001533 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001534
Tim Peters3a5e8b12006-04-11 01:44:07 +00001535 def __hash__(self):
1536 return id(self) # WRONG
1537
1538 because a hash result must be a (short) Python int but it was always
1539 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001540 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001541 was always usable as a hash value before this patch. That's no longer
1542 necessarily so.
1543
1544- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001545 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001546 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001547 #1454844)
1548
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001549- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1550 involving generators that have paused outside of any ``try`` or ``with``
1551 blocks. (In 2.5a1, a paused generator that was part of a reference
1552 cycle could not be garbage collected, regardless of whether it was
1553 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001554
Anthony Baxter51bcb682006-04-05 14:51:42 +00001555Extension Modules
1556-----------------
1557
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001558- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1559 is a macro.
1560
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001561- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1562 fails with an error condition.
1563
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001564- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1565
1566- Bug #1117761: bsddb.*open() no longer raises an exception when using
1567 the cachesize parameter.
1568
1569- Bug #1149413: bsddb.*open() no longer raises an exception when using
1570 a temporary db (file=None) with the 'n' flag to truncate on open.
1571
1572- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1573 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001574
Armin Rigoa9017c32006-04-19 11:50:27 +00001575- Patch #1062014: AF_UNIX sockets under Linux have a special
1576 abstract namespace that is now fully supported.
1577
Anthony Baxter51bcb682006-04-05 14:51:42 +00001578Library
1579-------
1580
Peter Astrand7d1d4362006-07-14 14:04:45 +00001581- Bug #1223937: subprocess.CalledProcessError reports the exit status
1582 of the process using the returncode attribute, instead of
1583 abusing errno.
1584
Tim Peters711bf302006-04-25 03:31:36 +00001585- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1586 a doctest to be skipped (the code is not run, and the expected output
1587 or exception is ignored).
1588
Nick Coghlanda2268f2006-04-24 04:37:15 +00001589- Fixed contextlib.nested to cope with exceptions being raised and
1590 caught inside exit handlers.
1591
Greg Wardab05edc2006-04-23 03:47:58 +00001592- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1593 hex, octal, or binary; add ``append_const`` action; keep going if
1594 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1595 added ``epilog`` for better help generation).
1596
Tim Peters21fbd572006-04-21 21:18:10 +00001597- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1598 called from a thread spawned as a side effect of importing a module.
1599
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001600- The pydoc module now supports documenting packages contained in
1601 .zip or .egg files.
1602
1603- The pkgutil module now has several new utility functions, such
1604 as ``walk_packages()`` to support working with packages that are either
1605 in the filesystem or zip files.
1606
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001607- The mailbox module can now modify and delete messages from
1608 mailboxes, in addition to simply reading them. Thanks to Gregory
1609 K. Johnson for writing the code, and to the 2005 Google Summer of
1610 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001611
Tim Petersc7605f22006-04-17 21:12:33 +00001612- The ``__del__`` method of class ``local`` in module ``_threading_local``
1613 returned before accomplishing any of its intended cleanup.
1614
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001615- Patch #790710: Add breakpoint command lists in pdb.
1616
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001617- Patch #1063914: Add Tkinter.Misc.clipboard_get().
1618
Martin v. Löwis4b501e62006-04-15 08:41:11 +00001619- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1620
Anthony Baxtere29002c2006-04-12 12:07:31 +00001621- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1622 Windows. Bug #1469163.
1623
Phillip J. Eby47032112006-04-11 01:07:43 +00001624- The warnings, linecache, inspect, traceback, site, and doctest modules
1625 were updated to work correctly with modules imported from zipfiles or
1626 via other PEP 302 __loader__ objects.
1627
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001628- Patch #1467770: Reduce usage of subprocess._active to processes which
1629 the application hasn't waited on.
1630
Martin v. Löwisb04dee92006-04-10 08:34:21 +00001631- Patch #1462222: Fix Tix.Grid.
1632
Neal Norwitza31bf182006-04-09 03:35:43 +00001633- Fix exception when doing glob.glob('anything*/')
1634
Skip Montanaro262fb922006-04-21 02:31:07 +00001635- The pstats.Stats class accepts an optional stream keyword argument to
1636 direct output to an alternate file-like object.
1637
Anthony Baxter51bcb682006-04-05 14:51:42 +00001638Build
1639-----
1640
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001641- The Makefile now has a reindent target, which runs reindent.py on
1642 the library.
1643
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001644- Patch #1470875: Building Python with MS Free Compiler
1645
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001646- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001647
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001648- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1649 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001650 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001651 CXX from --with-cxx-main, see description in README.
1652
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001653- Patch #1429775: Link extension modules with the shared libpython.
1654
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001655- Fixed a libffi build problem on MIPS systems.
1656
Tim Peters8931ff12006-05-13 23:28:20 +00001657- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1658 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1659 and "%zu" for unsigned integers of type ``size_t``.
1660
Anthony Baxter51bcb682006-04-05 14:51:42 +00001661Tests
1662-----
1663
Nick Coghlanda2268f2006-04-24 04:37:15 +00001664- test_contextlib now checks contextlib.nested can cope with exceptions
1665 being raised and caught inside exit handlers.
1666
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001667- test_cmd_line now checks operation of the -m and -c command switches
1668
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001669- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1670 it separately and by hand. It also wasn't cleaning up its changes to
1671 the current Decimal context.
1672
Thomas Woutersabd08882006-04-26 15:53:30 +00001673- regrtest.py now has a -M option to run tests that test the new limits of
1674 containers, on 64-bit architectures. Running these tests is only sensible
1675 on 64-bit machines with more than two gigabytes of memory. The argument
1676 passed is the maximum amount of memory for the tests to use.
1677
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001678Tools
1679-----
1680
1681- Added the Python benchmark suite pybench to the Tools/ directory;
1682 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001684Documentation
1685-------------
1686
Tim Petersb06d28c2006-05-12 01:57:59 +00001687- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1688
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001689- PEP 343: Added Context Types section to the library reference
1690 and attempted to bring other PEP 343 related documentation into
1691 line with the implementation and/or python-dev discussions.
1692
Tim Peters8dc73d22006-04-24 02:03:16 +00001693- Bug #1337990: clarified that ``doctest`` does not support examples
1694 requiring both expected output and an exception.
Anthony Baxter51bcb682006-04-05 14:51:42 +00001695

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001697What's New in Python 2.5 alpha 1?
1698=================================
1699
Anthony Baxterebed3f62006-04-03 15:03:44 +00001700*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001701
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001702Core and builtins
1703-----------------
1704
Nick Coghlan43832302006-04-23 17:04:07 +00001705- PEP 338: -m command line switch now delegates to runpy.run_module
1706 allowing it to support modules in packages and zipfiles
1707
Martin v. Löwisc661b882006-04-20 04:54:23 +00001708- On Windows, .DLL is not an accepted file name extension for
1709 extension modules anymore; extensions are only found if they
1710 end in .PYD.
1711
Martin v. Löwisea62d252006-04-03 10:56:49 +00001712- Bug #1421664: sys.stderr.encoding is now set to the same value as
1713 sys.stdout.encoding.
1714
Neal Norwitz92e212f2006-04-03 04:48:37 +00001715- __import__ accepts keyword arguments.
1716
Georg Brandlccadf842006-03-31 18:54:53 +00001717- Patch #1460496: round() now accepts keyword arguments.
1718
Anthony Baxter262c00a2006-03-30 10:53:17 +00001719- Fixed bug #1459029 - unicode reprs were double-escaped.
1720
Hye-Shik Changd478f342006-03-23 12:32:36 +00001721- Patch #1396919: The system scope threads are reenabled on FreeBSD
1722 5.4 and later versions.
1723
Neal Norwitze98ccf62006-03-23 05:39:47 +00001724- Bug #1115379: Compiling a Unicode string with an encoding declaration
1725 now gives a SyntaxError.
1726
Georg Brandlabd1ff82006-03-18 07:59:59 +00001727- Previously, Python code had no easy way to access the contents of a
1728 cell object. Now, a ``cell_contents`` attribute has been added
1729 (closes patch #1170323).
1730
Tim Peterscf79aac2006-03-16 01:14:46 +00001731- Patch #1123430: Python's small-object allocator now returns an arena to
1732 the system ``free()`` when all memory within an arena becomes unused
1733 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1734 freed. Some applications will see a drop in virtual memory size now,
1735 especially long-running applications that, from time to time, temporarily
1736 use a large number of small objects. Note that when Python returns an
1737 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001738 platform C library will in turn return that memory to the operating system.
1739 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001740 appears to be effective at least on Microsoft C and gcc-based systems.
1741 Thanks to Evan Jones for hard work and patience.
1742
Georg Brandl533ff6f2006-03-08 18:09:27 +00001743- Patch #1434038: property() now uses the getter's docstring if there is
1744 no "doc" argument given. This makes it possible to legitimately use
1745 property() as a decorator to produce a read-only property.
1746
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001747- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1748 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1749 of requiring an int or long in slicing and a few other contexts, enabling
1750 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1751
Neal Norwitz995acdf2006-03-07 05:01:00 +00001752- Fixed various bugs reported by Coverity's Prevent tool.
1753
Brett Cannonbf364092006-03-01 04:25:17 +00001754- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1755 new exception base class, BaseException, which has a new message attribute.
1756 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1757 Raising a string exception now raises a DeprecationWarning.
1758
Thomas Woutersfb609f42006-02-28 16:37:25 +00001759- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1760 explicitly relative, using 'from .module import name' to mean 'from the same
1761 package as this module is in. Imports without dots still default to the
1762 old relative-then-absolute, unless 'from __future__ import
1763 absolute_import' is used.
1764
Brett Cannona7446e32006-02-27 23:39:10 +00001765- Properly check if 'warnings' raises an exception (usually when a filter set
1766 to "error" is triggered) when raising a warning for raising string
1767 exceptions.
1768
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001769- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001770 The name was removed from Include/code.h.
1771
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001772- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001773
Guido van Rossum1968ad32006-02-25 22:38:04 +00001774- Patch 1433928:
1775 - The copy module now "copies" function objects (as atomic objects).
1776 - dict.__getitem__ now looks for a __missing__ hook before raising
1777 KeyError.
1778
Tim Peters84ef21c2006-02-28 20:39:06 +00001779- PEP 343: with statement implemented. Needs ``from __future__ import
1780 with_statement``. Use of 'with' as a variable will generate a warning.
1781 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001782 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001783 The following objects have __context__ methods:
1784 - The built-in file type.
1785 - The thread.LockType type.
1786 - The following types defined by the threading module:
1787 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1788 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001789
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001790- Fix the encodings package codec search function to only search
1791 inside its own package. Fixes problem reported in patch #1433198.
1792
1793 Note: Codec packages should implement and register their own
1794 codec search function. PEP 100 has the details.
1795
Tim Peters9ea89d22006-06-04 03:26:02 +00001796- PEP 353: Using ``Py_ssize_t`` as the index type.
1797
1798- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1799 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1800 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1801 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1802 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001803
Neal Norwitzfc76d632006-01-10 06:03:13 +00001804- Patch #1400181, fix unicode string formatting to not use the locale.
1805 This is how string objects work. u'%f' could use , instead of .
1806 for the decimal point. Now both strings and unicode always use periods.
1807
Neal Norwitz671b9e32006-01-09 07:07:12 +00001808- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1809 configure would break checking curses.h.
1810
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001811- Bug #959576: The pwd module is now builtin. This allows Python to be
1812 built on UNIX platforms without $HOME set.
1813
Neal Norwitzc10978f2005-12-19 06:07:16 +00001814- Bug #1072182, fix some potential problems if characters are signed.
1815
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001816- Bug #889500, fix line number on SyntaxWarning for global declarations.
1817
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001818- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1819
Neal Norwitze7214a12005-12-18 05:03:17 +00001820- Support for converting hex strings to floats no longer works.
1821 This was not portable. float('0x3') now raises a ValueError.
1822
Barry Warsaw2a38a862005-12-18 01:27:35 +00001823- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001824 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001825 is now displayed in interactive prompt banner.
1826
Georg Brandlfa166682005-12-17 21:45:17 +00001827- Implementation of PEP 341 - Unification of try/except and try/finally.
1828 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001829 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001830
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001831- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1832 now encodes backslash correctly.
1833
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001834- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1835
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001836- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001837 and long longs.
1838
Neal Norwitz67715f02005-11-09 06:59:35 +00001839- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001840 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001841 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001842
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001843- Replaced most Unicode charmap codecs with new ones using the
1844 new Unicode translate string feature in the builtin charmap
1845 codec; the codecs were created from the mapping tables available
1846 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1847 encodings now include a mapping for the Apple logo)
1848
Tim Peterse3547fd2005-12-16 23:13:57 +00001849- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001850
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001851- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001852
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001853- A new AST parser implementation was completed. The abstract
1854 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001855 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001856
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001857- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001858 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1859
Neal Norwitz708e51a2005-10-03 04:48:15 +00001860- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1861
Neal Norwitz11bd1192005-10-03 00:54:56 +00001862- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1863 Provide a warning when a directory is passed on the command line.
1864
Neal Norwitz40d37812005-10-02 01:48:49 +00001865- Fix segfault with invalid coding.
1866
1867- SF bug #772896: unknown encoding results in MemoryError.
1868
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001869- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001870 supported a __len__() method which evaluated to False when the iterator
1871 was empty.
1872
Guido van Rossum630db602005-09-20 18:49:54 +00001873- On 64-bit platforms, when __len__() returns a value that cannot be
1874 represented as a C int, raise OverflowError.
1875
Skip Montanarof8948ca2005-09-19 03:54:46 +00001876- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001877 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001878
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001879- SF bug #893549: parsing keyword arguments was broken with a few format
1880 codes.
1881
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001882- Changes donated by Elemental Security to make it work on AIX 5.3
1883 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1884 bug #105470: test_pwd fails on 64bit system (Opteron).
1885
Guido van Rossum539c6622005-09-14 17:49:54 +00001886- Changes donated by Elemental Security to make it work on HP-UX 11 on
1887 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1888
Georg Brandl4550b8d2005-08-26 06:43:52 +00001889- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001890 (fixes bug #1119418).
1891
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001892- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1893
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001894- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1895 exceptions that cause a function to exit.
1896
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001897- The implementation of set() and frozenset() was revised to use its
1898 own internal data structure. Memory consumption is reduced by 1/3
1899 and there are modest speed-ups as well. The API is unchanged.
1900
Tim Petersde7990b2005-07-17 23:45:23 +00001901- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1902
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001903- SF bug #1229429: PyObject_CallMethod failed to decrement some
1904 reference counts in some error exit cases.
1905
Tim Petersecc6e6a2005-07-10 22:30:55 +00001906- SF bug #1185883: Python's small-object memory allocator took over
1907 a block managed by the platform C library whenever a realloc specified
1908 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001909 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001910 portable way to copy data from the C-managed block into Python's
1911 small-object space without risking a memory fault. Python's small-object
1912 realloc now leaves such blocks under the control of the platform C
1913 realloc.
1914
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001915- SF bug #1232517: An overflow error was not detected properly when
1916 attempting to convert a large float to an int in os.utime().
1917
Raymond Hettinger3296e692005-06-29 23:29:56 +00001918- SF bug #1224347: hex longs now print with lowercase letters just
1919 like their int counterparts.
1920
Michael W. Hudson188d4362005-06-20 16:52:57 +00001921- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1922 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1923 interpreter states; back out that fix and do a better job (see
1924 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1925 for a longer write-up of the problem).
1926
Michael W. Hudsondf888462005-06-03 14:41:55 +00001927- SF patch #1180995: marshal now uses a binary format by default when
1928 serializing floats.
1929
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001930- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1931 the routines that promise to produce IEEE 754 binary representations
1932 of floats now simply copy bytes around.
1933
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001934- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1935 278.
1936
Brett Cannonc3647ac2005-04-26 03:45:26 +00001937- patch #1109424: int, long, float, complex, and unicode now check for the
1938 proper magic slot for type conversions when subclassed. Previously the
1939 magic slot was ignored during conversion. Semantics now match the way
1940 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001941 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001942 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001943 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001944
Barry Warsawc8d907c2005-04-19 23:43:40 +00001945- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1946 NULL, now raise an AttributeError when attempting to set or delete the
1947 attribute. Previously a TypeError was raised, but this was inconsistent
1948 with the equivalent pure-Python implementation.
1949
Michael W. Hudson774479c2005-04-18 08:46:17 +00001950- It is now safe to call PyGILState_Release() before
1951 PyEval_InitThreads() (note that if there is reason to believe there
1952 are multiple threads around you still must call PyEval_InitThreads()
1953 before using the Python API; this fix is for extension modules that
1954 have no way of knowing if Python is multi-threaded yet).
1955
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001956- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1957 disabled caused a crash.
1958
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001959- Bug #1165306: instancemethod_new allowed the creation of a method
1960 with im_class == im_self == NULL, which caused a crash when called.
1961
Tim Petersecc6e6a2005-07-10 22:30:55 +00001962- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001963 fixes the crash seen in bug #1165761
1964
Raymond Hettinger96229b12005-03-11 06:49:40 +00001965- Added two new builtins, any() and all().
1966
Brett Cannon409d8f22005-03-05 06:47:57 +00001967- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001968 (e.g., ``class C(): pass`` is no longer a syntax error).
1969 Patch #1176012 added support to the 'parser' module and 'compiler' package
1970 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001971
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001972- Patch #1115086: Support PY_LONGLONG in structmember.
1973
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001974- Bug #1155938: new style classes did not check that __init__() was
1975 returning None.
1976
Tim Petersecc6e6a2005-07-10 22:30:55 +00001977- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001978 ('\') with a specific error message.
1979
Martin v. Löwisff232d72005-03-03 09:24:38 +00001980- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1981
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001982- Bug #1124295: the __name__ attribute of file objects was
1983 inadvertently made inaccessible in restricted mode.
1984
Tim Petersecc6e6a2005-07-10 22:30:55 +00001985- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001986 an ferror() call.
1987
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001988- min() and max() now support key= arguments with the same meaning as in
1989 list.sort().
1990
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001991- The peephole optimizer now performs simple constant folding in expressions:
1992 (2+3) --> (5).
1993
Raymond Hettingera422c342005-01-11 03:03:27 +00001994- set and frozenset objects can now be marshalled. SF #1098985.
1995
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001996- Bug #1077106: Poor argument checking could cause memory corruption
1997 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001998
Jeremy Hyltonab630502005-02-04 18:44:06 +00001999- The parser did not complain about future statements in illegal
2000 positions. It once again reports a syntax error if a future
2001 statement occurs after anything other than a doc string.
2002
Neil Schemenauercf52c072005-08-12 17:34:58 +00002003- Change the %s format specifier for str objects so that it returns a
2004 unicode instance if the argument is not an instance of basestring and
2005 calling __str__ on the argument returns a unicode instance.
2006
Tim Petersf4e69282006-02-27 17:15:31 +00002007- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2008 current thread state when the auto-GIL-state machinery knows about
2009 it (since the thread state is being deleted, continuing to remember it
2010 can't help, but can hurt if another thread happens to get created with
2011 the same thread id).
2012
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002013Extension Modules
2014-----------------
2015

2019
Anthony Baxterfa869072006-03-20 05:21:58 +00002020- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
2021 In addition, the existing ulaw code was updated.
2022
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002023- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00002024 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002025
Neal Norwitz10be10c2006-03-16 06:50:13 +00002026- Everything under lib-old was removed. This includes the following modules:
2027 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00002028 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00002029 util, whatsound, whrandom, zmod
2030
2031- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2032
2033- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002034 is deprecated. The undocumented re.engine variable no longer exists.
2035
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002036- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2037 SS2 (single-shift 2) escape sequences correctly.
2038
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002039- The unicodedata module was updated to the 4.1 version of the Unicode
2040 database. The 3.2 version is still available as unicodedata.db_3_2_0
2041 for applications that require this specific version (such as IDNA).
2042
Neal Norwitzb62c4332006-03-04 18:35:47 +00002043- The timing module is no longer built by default. It was deprecated
2044 in PEP 4 in Python 2.0 or earlier.
2045
Guido van Rossum1968ad32006-02-25 22:38:04 +00002046- Patch 1433928: Added a new type, defaultdict, to the collections module.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002203- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2204 been renamed to have only a single underscore prefix. This was done to
2205 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002206
Nick Coghlan43832302006-04-23 17:04:07 +00002207- PEP 338: new module runpy defines a run_module function to support
2208 executing modules which provide access to source code or a code object
2209 via the PEP 302 import mechanisms.
2210
Anthony Baxter93f5b932006-04-03 08:05:07 +00002211- The email module's parsedate_tz function now sets the daylight savings

2219 in attribute values.
2220
Anthony Baxterc51ee692006-04-01 00:57:31 +00002221- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002222 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002223 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002224 module will not be built.
2225
Tim Petersc17976e2006-04-01 00:26:53 +00002226- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2227 aren't officially supported here, and trying to use them will probably
2228 raise an exception some day. But dicts have been allowed, and "mostly
2229 worked", so support for them won't go away without warning.
2230
Georg Brandl338ef7d2006-03-31 18:42:16 +00002231- Bug #1445068: getpass.getpass() can now be given an explicit stream
2232 argument to specify where to write the prompt.
2233

2249
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002250- email 4.0 package now integrated. This is largely the same as the email 3.0
2251 package that was included in Python 2.3, except that PEP 8 module names are
2252 now used (e.g. mail.message instead of email.Message). The MIME classes
2253 have been moved to a subpackage (e.g. email.mime.text instead of
2254 email.MIMEText). The old names are still supported for now. Several
2255 deprecated Message methods have been removed and lots of bugs have been
2256 fixed. More details can be found in the email package documentation.
2257
Walter Dörwald40108c92006-03-27 08:15:44 +00002258- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2259 (a subclass of tuple) that provides incremental decoders and encoders
2260 (a way to use stateful codecs without the stream API). Python functions
2261 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2262 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2263 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002264
Walter Dörwald067db482006-03-15 22:17:27 +00002265- Patch #1359365: Calling next() on a closed StringIO.String object raises
2266 a ValueError instead of a StopIteration now (like file and cString.String do).
2267 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2268 called before (like file and StringIO.StringIO do).

Tim Petersda1329b2006-02-27 16:50:01 +00002317- Patch #1349118: urllib now supports user:pass@ style proxy
Martin v. Löwis3e865952006-01-24 15:51:21 +00002318 specifications, raises IOErrors when proxies for unsupported protocols
2319 are defined, and uses the https proxy on https redirections.

2336
Neal Norwitz338e7862005-12-23 21:27:46 +00002337- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
2338 LoadError as documented, instead of IOError. For compatibility,
2339 LoadError subclasses IOError.
2340
Brett Cannon3cbd0382005-12-16 22:49:23 +00002341- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00002342 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2343 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2344 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2345 Ronald L. Rivest offered this advice for Python:
2346
2347 "The consensus of researchers in this area (at least as
2348 expressed at the NIST Hash Function Workshop 10/31/05),
2349 is that SHA-256 is a good choice for the time being, but
2350 that research should continue, and other alternatives may
2351 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002352
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002353- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandlb9256022005-08-24 18:46:39 +00002399- Patch #1062060: urllib.urlretrieve() now raises a new exception, named
2400 ContentTooShortException, when the actually downloaded size does not
2401 match the Content-Length header.
2402

2406 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002407 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002408

2422
Georg Brandla4a8b822005-07-15 09:13:21 +00002423- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
2424 parameter, but uses the usual "kwargs=None".
2425
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002426- textwrap now processes text chunks at O(n) speed instead of O(n**2).

2430 to W3C name (404 -> 'Not Found'). RFE #1216944.
2431
Georg Brandl9e43acf2005-07-04 17:16:07 +00002432- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2433 as this can cause problems with apps closing all file descriptors.

2446 Bug #1224621.
2447
Raymond Hettinger68c04532005-06-10 11:05:19 +00002448- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002449 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002450 the generate_tokens() function now accepts a callable argument that
2451 terminates by raising StopIteration.
2452
Georg Brandl9166e1a2005-06-04 09:20:03 +00002453- Bug #1196315: fix weakref.WeakValueDictionary constructor.

2467 them to PyPI.
2468
Raymond Hettinger267b8682005-03-27 10:47:39 +00002469- decimal operator and comparison methods now return NotImplemented
2470 instead of raising a TypeError when interacting with other types. This
2471 allows other classes to implement __radd__ style methods and have them
2472 work as expected.
2473
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002474- Bug #1163325: Decimal infinities failed to hash. Attempting to
2475 hash a NaN raised an InvalidOperation instead of a TypeError.
2476
Tim Petersecc6e6a2005-07-10 22:30:55 +00002477- Patch #918101: Add tarfile open mode r|* for auto-detection of the

2511
Guido van Rossumd0641422005-02-03 15:01:24 +00002512- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2513 disables recursive traversal through instance attributes, which can
2514 be exploited in various ways.
2515
Tim Peterse3547fd2005-12-16 23:13:57 +00002516- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002517 flags on the HTTP listening socket.
2518

Thomas Hellerd6c6e222005-01-20 19:20:16 +00002527- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2528
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002529- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2530
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002531- Enhancements to the csv module:
2532
2533 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002534 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002535 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002536 + Dialect parameter parsing has been re-implemented to improve error
2537 reporting.
2538 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2539 dictates.
2540 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002541 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002542 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002543 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2544 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002545 + reader now allows \r characters to be quoted (previously it only allowed
2546 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002547 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002548 + Dialect classes passed to the module are no longer instantiated by
2549 the module before being parsed (the former validation scheme required
2550 this, but the mechanism was unreliable).
2551 + The dialect registry now contains instances of the internal
2552 C-coded dialect type, rather than references to python objects.
2553 + the internal c-coded dialect type is now immutable.
2554 + register_dialect now accepts the same keyword dialect specifications
2555 as the reader and writer, allowing the user to register dialects
2556 without first creating a dialect class.
2557 + a configurable limit to the size of parsed fields has been added -
2558 previously, an unmatched quote character could result in the entire
2559 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002560 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002561 the parser field size limit (returning the former limit). The initial
2562 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002563 + A line_num attribute has been added to the reader object, which tracks
2564 the number of lines read from the source iterator. This is not
2565 the same as the number of records returned, as records can span
2566 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002567 + reader and writer objects were not being registered with the cyclic-GC.
2568 This has been fixed.
2569
Brett Cannone6539c42005-01-08 02:43:53 +00002570- _DummyThread objects in the threading module now delete self.__block that is
2571 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2572 lock primitives tend to be limited in number and thus should not be wasted on
2573 a _DummyThread object. Fixes bug #1089632.
2574

2578 (Bug #951915).
2579
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002580- locale.py now uses an updated locale alias table (built using
2581 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2582 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002583 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002584
Raymond Hettinger3557f422004-12-07 12:02:02 +00002585- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2586
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002587- the pickle module no longer accepts the deprecated None option in the
2588 args tuple returned by __reduce__().
2589
Brett Cannon84667c02004-12-07 03:25:18 +00002590- optparse now optionally imports gettext. This allows its use in setup.py.
2591
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002592- the pickle module no longer uses the deprecated bin parameter.
2593

2599
Raymond Hettinger664347b2004-12-04 21:21:53 +00002600- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2601 extended or overridden by subclasses. Formerly, the subclassed method would
2602 be ignored by the rest of the module. (Bug #1078905).
2603
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002604- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002605 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002606
Walter Dörwald36733692004-12-22 12:50:50 +00002607- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2608 once when a size argument is given. This prevents a buffer overflow in the
2609 tokenizer with very long source lines.
2610
Barry Warsaw538561e2006-01-01 21:48:54 +00002611- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2612 immediately after creating the object, without any intervening
2613 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002614
Skip Montanaro05885812005-01-16 20:48:27 +00002615- The reconvert.quote function can now emit triple-quoted strings. The
2616 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002617
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002618- ``UserString.MutableString`` now supports negative indices in
2619 ``__setitem__`` and ``__delitem__``
2620
Greg Ward40407942005-03-05 02:53:17 +00002621- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2622 correctly.
2623
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002624- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2625 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2626 character even if the user has passed a size parameter to get a proper
2627 line ending. Remove the special handling of a "\r\n" that has been split
2628 between two lines.
2629
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002630- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2631 about illegal code points. The codec now supports PEP 293 style error
2632 handlers.
2633
Walter Dörwald78a78b02005-09-01 12:04:29 +00002634- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002635 from the input stream, so that the output is a byte string in the correct
2636 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002637
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002638- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2639 considering it exactly like a '*'.
2640
Walter Dörwald007f8df2005-10-09 19:42:27 +00002641- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2642 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002643
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002644- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2645
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002646- Patch #1413711: Certain patterns of differences were making difflib
2647 touch the recursion limit.
2648
Walter Dörwald58917a62006-03-31 15:26:22 +00002649- Bug #947906: An object oriented interface has been added to the calendar
2650 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002651 called as a script (e.g. via ``python -mcalendar``). Localized month and
2652 weekday names can be ouput (even if an exotic encoding is used) using
2653 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002654
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002655Build
2656-----
2657
Neal Norwitz602d3392006-03-31 08:21:40 +00002658- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2659 by using -mieee gcc option.
2660

2662
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002663- Build support for Win64-AMD64 was added.
2664
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002665- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2666
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002667- Patch #881820: look for openpty and forkpty also in libbsd.
2668
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002669- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2670 The zlib module is now builtin on Windows.
2671
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002672- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2673
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002674- Bug #1189330: configure did not correctly determine the necessary
2675 value of LINKCC if python was built with GCC 4.0.
2676
Trent Mick8321b422005-07-26 02:29:21 +00002677- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2678 vulnerability in zlib 1.2.1 and 1.2.2.
2679
Brett Cannon08cd5982005-04-24 22:26:38 +00002680- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2681 flags that change binary compatibility. Changes were also made to
2682 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002683 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002684
Bob Ippolitoed233462005-03-29 13:47:59 +00002685- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2686 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2687 no longer exists). This configure patch makes things right.
2688
Martin v. Löwise2713be2005-03-08 15:03:08 +00002689- Bug #1158607: Build with --disable-unicode again.
2690
Brett Cannon46d96232005-02-16 00:07:19 +00002691- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2692 defined. Discovered as a result of not being able to build on OS X.
2693
Brett Cannon516592f2004-12-07 00:42:59 +00002694- setup.py now uses the directories specified in LDFLAGS using the -L option
2695 and in CPPFLAGS using the -I option for adding library and include
2696 directories, respectively, for compiling extension modules against. This has
2697 led to the core being compiled using the values in CPPFLAGS. It also removes
2698 the need for the special-casing of both DarwinPorts and Fink for darwin since
2699 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2700 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2701 Fink, ``-I/opt/local/include`` for DarwinPorts).
2702
Brett Cannon43802422005-02-10 20:48:03 +00002703- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2704 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2705 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2706 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002708C API
2709-----
2710
Tim Petersc9d78aa2006-03-26 23:27:58 +00002711- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2712 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2713 is obtained via the ``PyObject_`` family, it must be released via the
2714 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2715 always been officially true, but when Python's small-object allocator was
2716 introduced, an attempt was made to cater to a few extension modules
2717 discovered at the time that obtained memory via ``PyObject_New`` but
2718 released it via ``PyMem_DEL``. It's years later, and if such code still
2719 exists it will fail now (probably with segfaults, but calling wrong
2720 low-level memory management functions can yield many symptoms).
2721
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002722- Added a C API for set and frozenset objects.
2723
Raymond Hettinger66517482004-12-03 11:45:13 +00002724- Removed PyRange_New().
2725
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002726- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2727 mapping argument now. This string is used as a mapping table. Byte values
2728 greater than the length of the string and 0xFFFE are treated as undefined
2729 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002736
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002737- Patch #1276356: New resource "urlfetch" is implemented. This enables
2738 even impatient people to run tests that require remote files.
