Brett Cannon9adeab72006-09-20 18:34:28 +000095- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This

Georg Brandlec6c2df2006-09-11 09:38:35 +000098- Make _PyGILState_NoteThreadState() static, it was not used anywhere

518Core and builtins
519-----------------
520
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000521- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000522 compared equal or unequal to a string and a UnicodeDecodeError
523 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000524
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000525 Instead, the equal (==) and unequal (!=) comparison operators will
526 now issue a UnicodeWarning and interpret the two objects as
527 unequal. The UnicodeWarning can be filtered as desired using
528 the warning framework, e.g. silenced completely, turned into an
529 exception, logged, etc.
530
531 Note that compare operators other than equal and unequal will still
532 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000533
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000534- Fix segfault when doing string formatting on subclasses of long.
535
536- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
537 with new-style classes.
538
539- Fix bug related to __len__ functions returning negative values with
540 classic classes.
541
542- Patch #1538606, Fix __index__() clipping. There were some problems
543 discovered with the API and how integers that didn't fit into Py_ssize_t
544 were handled. This patch attempts to provide enough alternatives
545 to effectively use __index__.
546
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000547- Bug #1536021: __hash__ may now return long int; the final hash
548 value is obtained by invoking hash on the long int.
549
Thomas Hellerab1049c2006-08-08 17:37:00 +0000550- Bug #1536786: buffer comparison could emit a RuntimeWarning.
551
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000552- Bug #1535165: fixed a segfault in input() and raw_input() when
553 sys.stdin is closed.
554
Thomas Heller74d36f02006-08-04 18:17:40 +0000555- On Windows, the PyErr_Warn function is now exported from
556 the Python dll again.
557
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000558- Bug #1191458: tracing over for loops now produces a line event
559 on each iteration. Fixing this problem required changing the .pyc
560 magic number. This means that .pyc files generated before 2.5c1
561 will be regenerated.
562
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000563- Bug #1333982: string/number constants were inappropriately stored
564 in the byte code and co_consts even if they were not used, ie
565 immediately popped off the stack.
566
Georg Brandle9462c72006-08-04 18:03:37 +0000567- Fixed a reference-counting problem in property().

571-------
572
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000573- Fix a bug in the ``compiler`` package that caused invalid code to be
574 generated for generator expressions.
575
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000576- The distutils version has been changed to 2.5.0. The change to
577 keep it programmatically in sync with the Python version running
578 the code (introduced in 2.5b3) has been reverted. It will continue
579 to be maintained manually as static string literal.
580
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000581- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000582 and this cannot be converted to the required C type, an exception is
583 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000584 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000585
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000586- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000587 an exception.
588
Tim Petersc10c9d02006-09-05 02:18:09 +0000589- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000590 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000591 workarounds for clocks with low resolution, to stop the code yielding
592 duplicate UUIDs.
593
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000594- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
595 before raising SystemExit, allowing IDLE to honor quit() and exit().
596
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000597- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
598
Georg Brandl7a1af772006-08-14 21:55:28 +0000599- Patch #1536071: trace.py should now find the full module name of a
600 file correctly even on Windows.
601
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000602- logging's atexit hook now runs even if the rest of the module has
603 already been cleaned up.

624
Thomas Heller86720042006-08-14 11:17:48 +0000625- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
626 uses the _as_parameter_ attribute when objects are passed to foreign

Fred Drake53912162006-07-29 13:22:49 +0000676What's New in Python 2.5 beta 3?
677================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000678
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000679*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000680
681Core and builtins
682-----------------
683
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000684- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000685 returned a long (see PEP 353).
686
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000687- Bug #1515471: string.replace() accepts character buffers again.
688
Neal Norwitz07aadb12006-07-30 06:55:48 +0000689- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
690 This provides the proper warning for struct.pack().
691 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
692
Neal Norwitz0d62a062006-07-30 06:53:31 +0000693- Patch #1531113: Fix augmented assignment with yield expressions.
694 Also fix a SystemError when trying to assign to yield expressions.
695
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000696- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
697 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
698 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
699 excessive filesystem operations during imports.
700
Tim Petersbc24eee2006-07-27 01:14:53 +0000701- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
702 operations on signed longs that are formally undefined by C.
703 Unfortunately, at least one compiler now cares about that, so complicated
704 the code to make that compiler happy again.
705
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000706- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
707
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000708- Patch #1232023: Stop including current directory in search
709 path on Windows.
710
Neal Norwitze1fdb322006-07-21 05:32:28 +0000711- Fix some potential crashes found with failmalloc.
712
Neal Norwitze7563102006-07-17 01:00:16 +0000713- Fix warnings reported by Klocwork's static analysis tool.
714
Neal Norwitz84be93b2006-07-16 01:50:38 +0000715- Bug #1512814, Fix incorrect lineno's when code within a function
716 had more than 255 blank lines.
717
Georg Brandl9dceedb2006-07-12 15:31:17 +0000718- Patch #1521179: Python now accepts the standard options ``--help`` and
719 ``--version`` as well as ``/?`` on Windows.
720
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000721- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000722 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000723 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000724
Tim Peters112aad32006-07-19 00:03:19 +0000725- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000726 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000727 new ``sys._current_frames()`` returns a dictionary with one entry,
728 mapping the faux "thread id" 0 to the current frame.
729
Ronald Oussoren3075e162006-07-25 20:28:55 +0000730- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000731
Ronald Oussoren3075e162006-07-25 20:28:55 +0000732
Neal Norwitza1f10902006-07-12 07:28:29 +0000733Library
734-------
735
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000736- Correction of patch #1455898: In the mbcs decoder, set final=False
737 for stream decoder, but final=True for the decode function.
738
Georg Brandl07fec3a2006-08-01 18:49:24 +0000739- os.urandom no longer masks unrelated exceptions like SystemExit or
740 KeyboardInterrupt.
741
Tim Peters4643c2f2006-08-10 22:45:34 +0000742- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000743 shutil.copytree on Windows
744
Georg Brandle34ac7c2006-07-30 11:07:23 +0000745- Bug #1002398: The documentation for os.path.sameopenfile now correctly
746 refers to file descriptors, not file objects.
747
Tim Petersc10c9d02006-09-05 02:18:09 +0000748- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000749 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000750 #1513611, and probably others.
751
Georg Brandledd9b0d2006-07-29 09:33:26 +0000752- Bug #1441397: The compiler module now recognizes module and function
753 docstrings correctly as it did in Python 2.4.
754
Tim Peters6f681472006-07-27 23:44:37 +0000755- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
756 lost that tests are sorted by name before being run. This rarely
757 matters for well-written tests, but can create baffling symptoms if
758 side effects from one test to the next affect outcomes. ``DocTestFinder``
759 has been changed to sort the list of tests it returns.
760
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000761- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000762 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000763
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000764- Bug #978833: Really close underlying socket in _socketobject.close.
765
Georg Brandl8c036cc2006-08-20 13:15:39 +0000766- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
767 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000768
Georg Brandlcf0c1722006-07-26 07:23:32 +0000769- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
770 to recursive calls and call it with the failing package name.
771
Martin v. Löwis0b483032006-07-25 09:53:12 +0000772- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
773
Georg Brandlc13c34c2006-07-24 14:09:56 +0000774- Patch #1515343: Fix printing of deprecated string exceptions with a
775 value in the traceback module.
776
Greg Ward48fae7a2006-07-23 16:05:51 +0000777- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
778
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000779- Patch #1524429: Use repr() instead of backticks in Tkinter again.
780
Brett Cannoncaebe222006-07-18 04:41:36 +0000781- Bug #1520914: Change time.strftime() to accept a zero for any position in its
782 argument tuple. For arguments where zero is illegal, the value is forced to
783 the minimum value that is correct. This is to support an undocumented but
784 common way people used to fill in inconsequential information in the time
785 tuple pre-2.4.
786
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000787- Patch #1220874: Update the binhex module for Mach-O.
788
Barry Warsawb110bad2006-07-21 14:51:07 +0000789- The email package has improved RFC 2231 support, specifically for
790 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
791 (name*0=<blah>) parameter continuations. This may change the types of
792 values returned from email.message.Message.get_param() and friends.
793 Specifically in some cases where non-encoded continuations were used,
794 get_param() used to return a 3-tuple of (None, None, string) whereas now it
795 will just return the string (since non-encoded continuations don't have
796 charset and language parts).
797
798 Also, whereas % values were decoded in all parameter continuations, they are
799 now only decoded in encoded parameter parts.
800
Ronald Oussoren3075e162006-07-25 20:28:55 +0000801- Bug #1517990: IDLE keybindings on MacOS X now work correctly
802
803- Bug #1517996: IDLE now longer shows the default Tk menu when a
804 path browser, class browser or debugger is the frontmost window on MacOS X
805
Barry Warsaw00decd72006-07-27 23:43:15 +0000806- Patch #1520294: Support for getset and member descriptors in types.py,
807 inspect.py, and pydoc.py. Specifically, this allows for querying the type
808 of an object against these built-in types and more importantly, for getting
809 their docstrings printed in the interactive interpreter's help() function.

814
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000815- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
816 a socket operation on a socket with a timeout, the exception will be
817 caught correctly. Previously, the exception was not caught.
818
Thomas Heller1393d6a2006-07-28 21:43:20 +0000819- Patch #1529514: The _ctypes extension is now compiled on more
820 openbsd target platforms.
821
Tim Peters9cab5932006-07-28 00:30:00 +0000822- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
823 a memory leak, affecting pickles and deep copies.
824
Tim Petersbc24eee2006-07-27 01:14:53 +0000825- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000826 Paul Eggert.
827
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000828- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
829
Thomas Hellerce049a02006-07-14 17:51:14 +0000830- Patch #1521817: Index range checking on ctypes arrays containing
831 exactly one element enabled again. This allows iterating over these
832 arrays, without the need to check the array size before.
833
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000834- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000835 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000836 /dev/null in certain cases; this is now fixed.
837
Thomas Heller47d7a062006-07-12 08:43:47 +0000838- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
839 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000840
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000841- Because of a misspelled preprocessor symbol, ctypes was always
842 compiled without thread support; this is now fixed.
843
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000844- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
845 methods now allow their database parameter to be None as the
846 sleepycat API allows.
847
Matt Flemingec926502006-07-28 11:27:27 +0000848- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
849 bluetooth API compared with Linux and FreeBSD.
850
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000851Tests
852-----
853
854- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
855 how long the test file should take to play. Now accepts taking 2.93 secs
856 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
857
Georg Brandl4793aa32006-07-28 18:31:39 +0000858- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
859 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
860 run via ``regrtest.py``. Now they do.

868---
869
870- PythonLauncher now works correctly when the path to the script contains
871 characters that are treated specially by the shell (such as quotes).
872
873- Bug #1527397: PythonLauncher now launches scripts with the working directory
874 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000875 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000876 expect.

Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000887- Bug #1441486: The literal representation of -(sys.maxint - 1)
888 again evaluates to a int object, not a long.
889
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000890- Bug #1501934: The scope of global variables that are locally assigned
891 using augmented assignment is now correctly determined.
892
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000893- Bug #927248: Recursive method-wrapper objects can now safely

900 omit a default "error" argument for NULL pointer. This allows
901 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000902
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000903- Bug #1519018: 'as' is now validated properly in import statements.
904
Neal Norwitz28746ab2006-07-09 22:14:42 +0000905- On 64 bit systems, int literals that use less than 64 bits are
906 now ints rather than longs.
907
Neal Norwitzed657552006-07-10 00:04:44 +0000908- Bug #1512814, Fix incorrect lineno's when code at module scope
909 started after line 256.
910
Tim Peters32a83612006-07-10 21:08:24 +0000911- New function ``sys._current_frames()`` returns a dict mapping thread
912 id to topmost thread stack frame. This is for expert use, and is
913 especially useful for debugging application deadlocks. The functionality
914 was previously available in Fazal Majid's ``threadframe`` extension
915 module, but it wasn't possible to do this in a wholly threadsafe way from
916 an extension.

Brett Cannon53ab5b72006-06-22 16:49:14 +0000964- Bug #1510580: The 'warnings' module improperly required that a Warning
965 category be either a types.ClassType and a subclass of Warning. The proper
966 check is just that it is a subclass with Warning as the documentation states.
967
Georg Brandlad29e632006-06-21 17:45:17 +0000968- The compiler module now correctly compiles the new try-except-finally

Tim Peters112aad32006-07-19 00:03:19 +0000983- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
984 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
985 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000986
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000987- Assigning None to pointer type fields in ctypes structures possible

989
990- Fixed a segfault in _ctypes when ctypes.wintypes were imported
991 on non-Windows platforms.
992
993- Bug #1518190: The ctypes.c_void_p constructor now accepts any
994 integer or long, without range checking.
995
996- Patch #1517790: It is now possible to use custom objects in the ctypes
997 foreign function argtypes sequence as long as they provide a from_param
998 method, no longer is it required that the object is a ctypes type.
999

1018
Tim Peters32a83612006-07-10 21:08:24 +00001019- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001020 Previously, the slight difference could cause compilation errors of the
1021 'zlib' module on systems with more than one version of zlib.
1022
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001023- The MSI compileall step was fixed to also support a TARGETDIR

1054Core and builtins
1055-----------------
1056
Georg Brandla56b9152006-06-19 06:35:54 +00001057- Patch #1507676: Error messages returned by invalid abstract object operations
1058 (such as iterating over an integer) have been improved and now include the
1059 type of the offending object to help with debugging.
1060
Brett Cannonea3912b2006-06-13 21:46:41 +00001061- Bug #992017: A classic class that defined a __coerce__() method that returned
1062 its arguments swapped would infinitely recurse and segfault the interpreter.
1063
Neal Norwitz909eb122006-06-12 02:13:21 +00001064- Fix the socket tests so they can be run concurrently.
1065
Neal Norwitzb9845e72006-06-12 02:11:18 +00001066- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001067 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001068
Brett Cannon22565aa2006-06-09 22:31:23 +00001069- Bug #532646: object.__call__() will continue looking for the __call__
1070 attribute on objects until one without one is found. This leads to recursion
1071 when you take a class and set its __call__ attribute to an instance of the
1072 class. Originally fixed for classic classes, but this fix is for new-style.
1073 Removes the infinite_rec_3 crasher.
1074
Georg Brandl24250812006-06-09 18:45:48 +00001075- The string and unicode methods startswith() and endswith() now accept
1076 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1077
Brett Cannonde3b0522006-06-08 17:00:45 +00001078- Buffer objects, at the C level, never used the char buffer
1079 implementation even when the char buffer for the wrapped object was
1080 explicitly requested (originally returned the read or write buffer).
1081 Now a TypeError is raised if the char buffer is not present but is
1082 requested.
1083
Georg Brandlddbaa662006-06-04 21:56:52 +00001084- Patch #1346214: Statements like "if 0: suite" are now again optimized
1085 away like they were in Python 2.4.
1086
Georg Brandlb7c8f542006-05-27 12:30:25 +00001087- Builtin exceptions are now full-blown new-style classes instead of
1088 instances pretending to be classes, which speeds up exception handling
1089 by about 80% in comparison to 2.5a2.
1090
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001091- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1092 Unicode 4.1.
1093
Georg Brandlf4ef1162006-05-26 18:03:31 +00001094- Patch #921466: sys.path_importer_cache is now used to cache valid and
1095 invalid file paths for the built-in import machinery which leads to
1096 fewer open calls on startup.
1097
Tim Peters696cf432006-05-24 21:10:40 +00001098- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1099 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1100 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1101 the number of input digits (it was and remains linear-time for bases
1102 2, 4, 8, 16 and 32).
1103
Tim Petersb713ec22006-05-23 18:45:30 +00001104- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1105 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1106 an integer close to ``sys.maxint``. This was repaired by patch
1107 #1335972, which also gives a nice speedup.
1108
Richard Jonescebbefc2006-05-23 18:28:17 +00001109- Patch #1337051: reduced size of frame objects.
1110
1111- PyErr_NewException now accepts a tuple of base classes as its
1112 "base" parameter.
1113
Richard Jones7c88dcc2006-05-23 10:37:38 +00001114- Patch #876206: function call speedup by retaining allocated frame
1115 objects.
1116
Georg Brandl7b90e162006-05-18 07:01:27 +00001117- Bug #1462152: file() now checks more thoroughly for invalid mode
1118 strings and removes a possible "U" before passing the mode to the
1119 C library function.
1120
Neal Norwitz1004a532006-05-15 07:17:23 +00001121- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1122
Neal Norwitz373f0a72006-05-15 07:04:36 +00001123- Bug #1487966: Fix SystemError with conditional expression in assignment
1124
Martin v. Löwis879768d2006-05-11 13:28:43 +00001125- WindowsError now has two error code attributes: errno, which carries
1126 the error values from errno.h, and winerror, which carries the error
1127 values from winerror.h. Previous versions put the winerror.h values
1128 (from GetLastError()) into the errno attribute.
1129
Martin v. Löwis77736712006-05-04 05:51:03 +00001130- Patch #1475845: Raise IndentationError for unexpected indent.
1131
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001132- Patch #1479181: split open() and file() from being aliases for each other.
1133
Tim Peters44bd9862006-06-01 13:49:23 +00001134- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1135 methods were always silently ignored by dictionaries when comparing keys.
1136 They are now passed through (except when using the C API function
1137 ``PyDict_GetItem()``, whose semantics did not change).
1138
1139- Bug #1456209: In some obscure cases it was possible for a class with a
1140 custom ``__eq__()`` method to confuse dict internals when class instances
1141 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1142 No, you don't have any code that did this ;-)

1150
Brett Cannon6ee7d012006-06-08 16:23:04 +00001151- Change binascii.hexlify to accept a read-only buffer instead of only a char
1152 buffer and actually follow its documentation.
1153
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001154- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1155
Nick Coghlanc649ec52006-05-29 12:43:05 +00001156- Patch #1478788 (modified version): The functional extension module has
1157 been renamed to _functools and a functools Python wrapper module added.
1158 This provides a home for additional function related utilities that are
1159 not specifically about functional programming. See PEP 309.
1160
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001161- Patch #1493701: performance enhancements for struct module.

1166 copy() method.
1167
Andrew MacIntyre92913322006-06-13 15:04:24 +00001168- Patch #1454481: thread stack size is now tunable at runtime for thread
1169 enabled builds on Windows and systems with Posix threads support.
1170
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001171- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1172 (up to the system limit of 32K characters).
1173
1174- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1175 As a result, these functions now raise WindowsError instead of OSError.
1176
Tim Peters7a822da2006-05-25 21:50:17 +00001177- ``time.clock()`` on Win64 should use the high-performance Windows
1178 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1179 Windows platforms).
1180
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001181- Calling Tk_Init twice is refused if the first call failed as that
1182 may deadlock.
1183
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001184- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1185 accept it without potentially using an uninitialized pointer.
1186
1187- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods

Gregory P. Smith3c228b12006-06-05 23:59:37 +00001197- bsddb: the __len__ method of a DB object has been fixed to return correct
1198 results. It could previously incorrectly return 0 in some cases.
1199 Fixes SF bug 1493322 (pybsddb bug 1184012).
1200
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001201- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1202 aborts the db transaction safely when a modifier callback fails.
1203 Fixes SF python patch/bug #1408584.
1204
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001205- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001206 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001207 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1208 database calls that would previously deadlock. [SF python bug #775414]

1239
Tim Peters43898b42006-06-14 04:09:25 +00001240- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1241 guarantee that adjacent triples in the return list always describe
1242 non-adjacent blocks. Previously, a pair of matching blocks could end
1243 up being described by multiple adjacent triples that formed a partition
1244 of the matching pair.

1253
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001254- The wsgiref package has been added to the standard library.
1255
Nick Coghlan676725d2006-06-08 13:54:49 +00001256- The functions update_wrapper() and wraps() have been added to the functools
1257 module. These make it easier to copy relevant metadata from the original
1258 function when writing wrapper functions.
1259
Tim Petersd6a9eef2006-06-05 01:48:21 +00001260- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1261 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001262
Martin v. Löwis3f767792006-06-04 19:36:28 +00001263- Patch #1359618: Speed up charmap encoder by using a trie structure
1264 for lookup.
1265
Tim Petersd609b1a2006-06-02 23:22:51 +00001266- The functions in the ``pprint`` module now sort dictionaries by key
1267 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1268 if and only if its display required more than one line, although that
1269 wasn't documented. The new behavior increases predictability; e.g.,
1270 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.

1293 stdout arguments, making it possible to redirect input and output
1294 for remote debugging.
1295
1296- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1297 a couple of issues, notably handling of long file names using the
1298 GNU LONGNAME extension.
1299
1300- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1301 new flag when ``name`` is already the name of an option flag.
1302
1303- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1304 package.

1348-----------------
1349
Thomas Heller1b046642006-04-18 18:51:06 +00001350- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1351 by converting these apis from macros into exported functions again:
1352
1353 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1354 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1355 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1356 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1357 PyRun_String Py_CompileString
1358
Martin v. Löwis45294a92006-04-18 06:24:08 +00001359- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1360
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001361- All uses of PyStructSequence_InitType have been changed to initialize
1362 the type objects only once, even if the interpreter is initialized
1363 multiple times.
1364
Neal Norwitz61546162006-04-14 05:20:28 +00001365- Bug #1454485, array.array('u') could crash the interpreter. This was
1366 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1367 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1368
1369- Py_UNICODE is unsigned. It was always documented as unsigned, but
1370 due to a bug had a signed value in previous versions.
1371
Tim Peters3a5e8b12006-04-11 01:44:07 +00001372- Patch #837242: ``id()`` of any Python object always gives a positive
1373 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1374 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001375 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001376 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001377
Tim Peters3a5e8b12006-04-11 01:44:07 +00001378 def __hash__(self):
1379 return id(self) # WRONG
1380
1381 because a hash result must be a (short) Python int but it was always
1382 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001383 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001384 was always usable as a hash value before this patch. That's no longer
1385 necessarily so.
1386
1387- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001388 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001389 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001390 #1454844)
1391
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001392- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1393 involving generators that have paused outside of any ``try`` or ``with``
1394 blocks. (In 2.5a1, a paused generator that was part of a reference
1395 cycle could not be garbage collected, regardless of whether it was
1396 paused in a ``try`` or ``with`` block.)

Tim Peters711bf302006-04-25 03:31:36 +00001428- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes

1430 or exception is ignored).
1431
Nick Coghlanda2268f2006-04-24 04:37:15 +00001432- Fixed contextlib.nested to cope with exceptions being raised and
1433 caught inside exit handlers.
1434
Greg Wardab05edc2006-04-23 03:47:58 +00001435- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1436 hex, octal, or binary; add ``append_const`` action; keep going if
1437 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1438 added ``epilog`` for better help generation).
1439
Tim Peters21fbd572006-04-21 21:18:10 +00001440- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1441 called from a thread spawned as a side effect of importing a module.
1442
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001443- The pydoc module now supports documenting packages contained in
1444 .zip or .egg files.
1445
1446- The pkgutil module now has several new utility functions, such
1447 as ``walk_packages()`` to support working with packages that are either
1448 in the filesystem or zip files.
1449
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001450- The mailbox module can now modify and delete messages from
1451 mailboxes, in addition to simply reading them. Thanks to Gregory
1452 K. Johnson for writing the code, and to the 2005 Google Summer of
1453 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001454
Tim Petersc7605f22006-04-17 21:12:33 +00001455- The ``__del__`` method of class ``local`` in module ``_threading_local``
1456 returned before accomplishing any of its intended cleanup.
1457
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001458- Patch #790710: Add breakpoint command lists in pdb.

Tim Peters8931ff12006-05-13 23:28:20 +00001500- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1501 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1502 and "%zu" for unsigned integers of type ``size_t``.
1503

1505-----
1506
Nick Coghlanda2268f2006-04-24 04:37:15 +00001507- test_contextlib now checks contextlib.nested can cope with exceptions
1508 being raised and caught inside exit handlers.
1509
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001510- test_cmd_line now checks operation of the -m and -c command switches
1511
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001512- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1513 it separately and by hand. It also wasn't cleaning up its changes to
1514 the current Decimal context.
1515
Thomas Woutersabd08882006-04-26 15:53:30 +00001516- regrtest.py now has a -M option to run tests that test the new limits of
1517 containers, on 64-bit architectures. Running these tests is only sensible
1518 on 64-bit machines with more than two gigabytes of memory. The argument
1519 passed is the maximum amount of memory for the tests to use.

1523
1524- Added the Python benchmark suite pybench to the Tools/ directory;
1525 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001527Documentation
1528-------------
1529
Tim Petersb06d28c2006-05-12 01:57:59 +00001530- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1531
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001532- PEP 343: Added Context Types section to the library reference
1533 and attempted to bring other PEP 343 related documentation into
1534 line with the implementation and/or python-dev discussions.
1535
Tim Peters8dc73d22006-04-24 02:03:16 +00001536- Bug #1337990: clarified that ``doctest`` does not support examples
1537 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001540What's New in Python 2.5 alpha 1?
1541=================================
1542
Anthony Baxterebed3f62006-04-03 15:03:44 +00001543*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001544
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001545Core and builtins
1546-----------------
1547
Nick Coghlan43832302006-04-23 17:04:07 +00001548- PEP 338: -m command line switch now delegates to runpy.run_module
1549 allowing it to support modules in packages and zipfiles
1550
Martin v. Löwisc661b882006-04-20 04:54:23 +00001551- On Windows, .DLL is not an accepted file name extension for
1552 extension modules anymore; extensions are only found if they
1553 end in .PYD.
1554
Martin v. Löwisea62d252006-04-03 10:56:49 +00001555- Bug #1421664: sys.stderr.encoding is now set to the same value as
1556 sys.stdout.encoding.
1557
Neal Norwitz92e212f2006-04-03 04:48:37 +00001558- __import__ accepts keyword arguments.
1559
Georg Brandlccadf842006-03-31 18:54:53 +00001560- Patch #1460496: round() now accepts keyword arguments.
1561
Anthony Baxter262c00a2006-03-30 10:53:17 +00001562- Fixed bug #1459029 - unicode reprs were double-escaped.
1563
Hye-Shik Changd478f342006-03-23 12:32:36 +00001564- Patch #1396919: The system scope threads are reenabled on FreeBSD
1565 5.4 and later versions.
1566
Neal Norwitze98ccf62006-03-23 05:39:47 +00001567- Bug #1115379: Compiling a Unicode string with an encoding declaration
1568 now gives a SyntaxError.
1569
Georg Brandlabd1ff82006-03-18 07:59:59 +00001570- Previously, Python code had no easy way to access the contents of a
1571 cell object. Now, a ``cell_contents`` attribute has been added
1572 (closes patch #1170323).
1573
Tim Peterscf79aac2006-03-16 01:14:46 +00001574- Patch #1123430: Python's small-object allocator now returns an arena to
1575 the system ``free()`` when all memory within an arena becomes unused
1576 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1577 freed. Some applications will see a drop in virtual memory size now,
1578 especially long-running applications that, from time to time, temporarily
1579 use a large number of small objects. Note that when Python returns an
1580 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001581 platform C library will in turn return that memory to the operating system.
1582 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001583 appears to be effective at least on Microsoft C and gcc-based systems.
1584 Thanks to Evan Jones for hard work and patience.
1585
Georg Brandl533ff6f2006-03-08 18:09:27 +00001586- Patch #1434038: property() now uses the getter's docstring if there is
1587 no "doc" argument given. This makes it possible to legitimately use
1588 property() as a decorator to produce a read-only property.
1589
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001590- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1591 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1592 of requiring an int or long in slicing and a few other contexts, enabling
1593 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1594
Neal Norwitz995acdf2006-03-07 05:01:00 +00001595- Fixed various bugs reported by Coverity's Prevent tool.
1596
Brett Cannonbf364092006-03-01 04:25:17 +00001597- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1598 new exception base class, BaseException, which has a new message attribute.
1599 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1600 Raising a string exception now raises a DeprecationWarning.
1601
Thomas Woutersfb609f42006-02-28 16:37:25 +00001602- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1603 explicitly relative, using 'from .module import name' to mean 'from the same
1604 package as this module is in. Imports without dots still default to the
1605 old relative-then-absolute, unless 'from __future__ import
1606 absolute_import' is used.
1607
Brett Cannona7446e32006-02-27 23:39:10 +00001608- Properly check if 'warnings' raises an exception (usually when a filter set
1609 to "error" is triggered) when raising a warning for raising string
1610 exceptions.
1611
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001612- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001613 The name was removed from Include/code.h.
1614
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001615- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001616
Guido van Rossum1968ad32006-02-25 22:38:04 +00001617- Patch 1433928:
1618 - The copy module now "copies" function objects (as atomic objects).
1619 - dict.__getitem__ now looks for a __missing__ hook before raising
1620 KeyError.
1621
Tim Peters84ef21c2006-02-28 20:39:06 +00001622- PEP 343: with statement implemented. Needs ``from __future__ import
1623 with_statement``. Use of 'with' as a variable will generate a warning.
1624 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001625 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001626 The following objects have __context__ methods:
1627 - The built-in file type.
1628 - The thread.LockType type.
1629 - The following types defined by the threading module:
1630 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1631 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001632
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001633- Fix the encodings package codec search function to only search
1634 inside its own package. Fixes problem reported in patch #1433198.
1635
1636 Note: Codec packages should implement and register their own
1637 codec search function. PEP 100 has the details.
1638
Tim Peters9ea89d22006-06-04 03:26:02 +00001639- PEP 353: Using ``Py_ssize_t`` as the index type.
1640
1641- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1642 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1643 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1644 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1645 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001646
Neal Norwitzfc76d632006-01-10 06:03:13 +00001647- Patch #1400181, fix unicode string formatting to not use the locale.
1648 This is how string objects work. u'%f' could use , instead of .
1649 for the decimal point. Now both strings and unicode always use periods.
1650
Neal Norwitz671b9e32006-01-09 07:07:12 +00001651- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1652 configure would break checking curses.h.
1653
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001654- Bug #959576: The pwd module is now builtin. This allows Python to be
1655 built on UNIX platforms without $HOME set.
1656
Neal Norwitzc10978f2005-12-19 06:07:16 +00001657- Bug #1072182, fix some potential problems if characters are signed.
1658
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001659- Bug #889500, fix line number on SyntaxWarning for global declarations.
1660
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001661- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1662
Neal Norwitze7214a12005-12-18 05:03:17 +00001663- Support for converting hex strings to floats no longer works.
1664 This was not portable. float('0x3') now raises a ValueError.
1665
Barry Warsaw2a38a862005-12-18 01:27:35 +00001666- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001667 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001668 is now displayed in interactive prompt banner.
1669
Georg Brandlfa166682005-12-17 21:45:17 +00001670- Implementation of PEP 341 - Unification of try/except and try/finally.
1671 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001672 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001673
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001674- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1675 now encodes backslash correctly.
1676
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001677- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1678
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001679- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001680 and long longs.
1681
Neal Norwitz67715f02005-11-09 06:59:35 +00001682- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001683 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001684 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001685
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001686- Replaced most Unicode charmap codecs with new ones using the
1687 new Unicode translate string feature in the builtin charmap
1688 codec; the codecs were created from the mapping tables available
1689 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1690 encodings now include a mapping for the Apple logo)
1691
Tim Peterse3547fd2005-12-16 23:13:57 +00001692- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001693
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001694- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001695
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001696- A new AST parser implementation was completed. The abstract
1697 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001698 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001699
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001700- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001701 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1702
Neal Norwitz708e51a2005-10-03 04:48:15 +00001703- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1704
Neal Norwitz11bd1192005-10-03 00:54:56 +00001705- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1706 Provide a warning when a directory is passed on the command line.
1707
Neal Norwitz40d37812005-10-02 01:48:49 +00001708- Fix segfault with invalid coding.
1709
1710- SF bug #772896: unknown encoding results in MemoryError.
1711
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001712- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001713 supported a __len__() method which evaluated to False when the iterator
1714 was empty.
1715
Guido van Rossum630db602005-09-20 18:49:54 +00001716- On 64-bit platforms, when __len__() returns a value that cannot be
1717 represented as a C int, raise OverflowError.
1718
Skip Montanarof8948ca2005-09-19 03:54:46 +00001719- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001720 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001721
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001722- SF bug #893549: parsing keyword arguments was broken with a few format
1723 codes.
1724
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001725- Changes donated by Elemental Security to make it work on AIX 5.3
1726 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1727 bug #105470: test_pwd fails on 64bit system (Opteron).
1728
Guido van Rossum539c6622005-09-14 17:49:54 +00001729- Changes donated by Elemental Security to make it work on HP-UX 11 on
1730 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1731
Georg Brandl4550b8d2005-08-26 06:43:52 +00001732- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001733 (fixes bug #1119418).
1734
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001735- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1736
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001737- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1738 exceptions that cause a function to exit.
1739
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001740- The implementation of set() and frozenset() was revised to use its
1741 own internal data structure. Memory consumption is reduced by 1/3
1742 and there are modest speed-ups as well. The API is unchanged.
1743
Tim Petersde7990b2005-07-17 23:45:23 +00001744- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1745
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001746- SF bug #1229429: PyObject_CallMethod failed to decrement some
1747 reference counts in some error exit cases.
1748
Tim Petersecc6e6a2005-07-10 22:30:55 +00001749- SF bug #1185883: Python's small-object memory allocator took over
1750 a block managed by the platform C library whenever a realloc specified
1751 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001752 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001753 portable way to copy data from the C-managed block into Python's
1754 small-object space without risking a memory fault. Python's small-object
1755 realloc now leaves such blocks under the control of the platform C
1756 realloc.
1757
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001758- SF bug #1232517: An overflow error was not detected properly when
1759 attempting to convert a large float to an int in os.utime().
1760
Raymond Hettinger3296e692005-06-29 23:29:56 +00001761- SF bug #1224347: hex longs now print with lowercase letters just
1762 like their int counterparts.
1763
Michael W. Hudson188d4362005-06-20 16:52:57 +00001764- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1765 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1766 interpreter states; back out that fix and do a better job (see
1767 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1768 for a longer write-up of the problem).
1769
Michael W. Hudsondf888462005-06-03 14:41:55 +00001770- SF patch #1180995: marshal now uses a binary format by default when
1771 serializing floats.
1772
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001773- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1774 the routines that promise to produce IEEE 754 binary representations
1775 of floats now simply copy bytes around.
1776
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001777- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1778 278.
1779
Brett Cannonc3647ac2005-04-26 03:45:26 +00001780- patch #1109424: int, long, float, complex, and unicode now check for the
1781 proper magic slot for type conversions when subclassed. Previously the
1782 magic slot was ignored during conversion. Semantics now match the way
1783 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001784 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001785 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001786 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001787
Barry Warsawc8d907c2005-04-19 23:43:40 +00001788- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1789 NULL, now raise an AttributeError when attempting to set or delete the
1790 attribute. Previously a TypeError was raised, but this was inconsistent
1791 with the equivalent pure-Python implementation.
1792
Michael W. Hudson774479c2005-04-18 08:46:17 +00001793- It is now safe to call PyGILState_Release() before
1794 PyEval_InitThreads() (note that if there is reason to believe there
1795 are multiple threads around you still must call PyEval_InitThreads()
1796 before using the Python API; this fix is for extension modules that
1797 have no way of knowing if Python is multi-threaded yet).
1798
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001799- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1800 disabled caused a crash.
1801
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001802- Bug #1165306: instancemethod_new allowed the creation of a method
1803 with im_class == im_self == NULL, which caused a crash when called.
1804
Tim Petersecc6e6a2005-07-10 22:30:55 +00001805- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001806 fixes the crash seen in bug #1165761
1807
Raymond Hettinger96229b12005-03-11 06:49:40 +00001808- Added two new builtins, any() and all().
1809
Brett Cannon409d8f22005-03-05 06:47:57 +00001810- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001811 (e.g., ``class C(): pass`` is no longer a syntax error).
1812 Patch #1176012 added support to the 'parser' module and 'compiler' package
1813 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001814
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001815- Patch #1115086: Support PY_LONGLONG in structmember.
1816
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001817- Bug #1155938: new style classes did not check that __init__() was
1818 returning None.
1819
Tim Petersecc6e6a2005-07-10 22:30:55 +00001820- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001821 ('\') with a specific error message.
1822
Martin v. Löwisff232d72005-03-03 09:24:38 +00001823- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1824
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001825- Bug #1124295: the __name__ attribute of file objects was
1826 inadvertently made inaccessible in restricted mode.
1827
Tim Petersecc6e6a2005-07-10 22:30:55 +00001828- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001829 an ferror() call.
1830
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001831- min() and max() now support key= arguments with the same meaning as in
1832 list.sort().
1833
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001834- The peephole optimizer now performs simple constant folding in expressions:
1835 (2+3) --> (5).
1836
Raymond Hettingera422c342005-01-11 03:03:27 +00001837- set and frozenset objects can now be marshalled. SF #1098985.
1838
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001839- Bug #1077106: Poor argument checking could cause memory corruption
1840 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001841
Jeremy Hyltonab630502005-02-04 18:44:06 +00001842- The parser did not complain about future statements in illegal
1843 positions. It once again reports a syntax error if a future
1844 statement occurs after anything other than a doc string.
1845
Neil Schemenauercf52c072005-08-12 17:34:58 +00001846- Change the %s format specifier for str objects so that it returns a
1847 unicode instance if the argument is not an instance of basestring and
1848 calling __str__ on the argument returns a unicode instance.
1849
Tim Petersf4e69282006-02-27 17:15:31 +00001850- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1851 current thread state when the auto-GIL-state machinery knows about
1852 it (since the thread state is being deleted, continuing to remember it
1853 can't help, but can hurt if another thread happens to get created with
1854 the same thread id).
1855

1884 for applications that require this specific version (such as IDNA).
1885
Neal Norwitzb62c4332006-03-04 18:35:47 +00001886- The timing module is no longer built by default. It was deprecated

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002046- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2047 been renamed to have only a single underscore prefix. This was done to
2048 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002049
Nick Coghlan43832302006-04-23 17:04:07 +00002050- PEP 338: new module runpy defines a run_module function to support
2051 executing modules which provide access to source code or a code object
2052 via the PEP 302 import mechanisms.
2053
Anthony Baxter93f5b932006-04-03 08:05:07 +00002054- The email module's parsedate_tz function now sets the daylight savings

2062 in attribute values.
2063
Anthony Baxterc51ee692006-04-01 00:57:31 +00002064- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002065 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002066 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002067 module will not be built.
2068
Tim Petersc17976e2006-04-01 00:26:53 +00002069- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2070 aren't officially supported here, and trying to use them will probably
2071 raise an exception some day. But dicts have been allowed, and "mostly
2072 worked", so support for them won't go away without warning.
2073
Georg Brandl338ef7d2006-03-31 18:42:16 +00002074- Bug #1445068: getpass.getpass() can now be given an explicit stream

2092
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002093- email 4.0 package now integrated. This is largely the same as the email 3.0
2094 package that was included in Python 2.3, except that PEP 8 module names are
2095 now used (e.g. mail.message instead of email.Message). The MIME classes
2096 have been moved to a subpackage (e.g. email.mime.text instead of
2097 email.MIMEText). The old names are still supported for now. Several
2098 deprecated Message methods have been removed and lots of bugs have been
2099 fixed. More details can be found in the email package documentation.
2100
Walter Dörwald40108c92006-03-27 08:15:44 +00002101- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2102 (a subclass of tuple) that provides incremental decoders and encoders
2103 (a way to use stateful codecs without the stream API). Python functions
2104 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2105 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2106 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002107

2109 a ValueError instead of a StopIteration now (like file and cString.String do).
2110 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2111 called before (like file and StringIO.StringIO do).

2186 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2187 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2188 Ronald L. Rivest offered this advice for Python:
2189
2190 "The consensus of researchers in this area (at least as
2191 expressed at the NIST Hash Function Workshop 10/31/05),
2192 is that SHA-256 is a good choice for the time being, but
2193 that research should continue, and other alternatives may
2194 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002195
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002196- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandl9166e1a2005-06-04 09:20:03 +00002296- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2297
Georg Brandl268e61c2005-06-03 14:28:50 +00002298- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2299 component of the path.
2300
Skip Montanaro174dd222005-05-14 20:54:16 +00002301- Patch #1120353: The xmlrpclib module provides better, more transparent,
2302 support for datetime.{datetime,date,time} objects. With use_datetime set
2303 to True, applications shouldn't have to fiddle with the DateTime wrapper
2304 class at all.
2305
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002306- distutils.commands.upload was added to support uploading distribution
2307 files to PyPI.
2308
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002309- distutils.commands.register now encodes the data as UTF-8 before posting
2310 them to PyPI.
2311
Raymond Hettinger267b8682005-03-27 10:47:39 +00002312- decimal operator and comparison methods now return NotImplemented
2313 instead of raising a TypeError when interacting with other types. This
2314 allows other classes to implement __radd__ style methods and have them
2315 work as expected.
2316
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002317- Bug #1163325: Decimal infinities failed to hash. Attempting to
2318 hash a NaN raised an InvalidOperation instead of a TypeError.
2319
Tim Petersecc6e6a2005-07-10 22:30:55 +00002320- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002321 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2322
Martin v. Löwis00a73e72005-03-04 19:40:34 +00002323- Patch #1043890: Add extractall method to tarfile.
2324
Martin v. Löwisc72dd382005-03-04 13:50:17 +00002325- Patch #1075887: Don't require MSVC in distutils if there is nothing
2326 to build.
2327
Martin v. Löwis637431b2005-03-03 23:12:42 +00002328- Patch #1103407: Properly deal with tarfile iterators when untarring
2329 symbolic links on Windows.
2330
Tim Petersecc6e6a2005-07-10 22:30:55 +00002331- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +00002332 profile.py if available.
2333
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00002334- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
2335
Martin v. Löwisc5574e82005-03-03 10:57:37 +00002336- Patch #1117454: Remove code to special-case cookies without values
2337 in LWPCookieJar.
2338
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00002339- Patch #1117339: Add cookielib special name tests.
2340
Martin v. Löwise869eb12005-03-03 09:46:07 +00002341- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
2342
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00002343- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
2344
Martin v. Löwisdf241532005-03-03 08:17:42 +00002345- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
2346
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00002347- Patch #1104111: Alter setup.py --help and --help-commands.
2348
Martin v. Löwis4afe1542005-03-01 08:09:28 +00002349- Patch #1121234: Properly cleanup _exit and tkerror commands.
2350
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00002351- Patch #1049151: xdrlib now unpacks booleans as True or False.
2352
Raymond Hettingerbab41432005-02-05 01:31:19 +00002353- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2354
Guido van Rossumd0641422005-02-03 15:01:24 +00002355- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2356 disables recursive traversal through instance attributes, which can
2357 be exploited in various ways.
2358
Tim Peterse3547fd2005-12-16 23:13:57 +00002359- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002360 flags on the HTTP listening socket.
2361
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002362- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2363 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2364
Fred Drakefbdeaad2006-07-29 16:56:15 +00002365- Patches #893642, #1039083: add allow_none, encoding arguments to
2366 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002367
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002368- Bug #1110478: Revert os.environ.update to do putenv again.
2369
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002370- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2371
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002372- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2373
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002374- Enhancements to the csv module:
2375
2376 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002377 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002378 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002379 + Dialect parameter parsing has been re-implemented to improve error
2380 reporting.
2381 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2382 dictates.
2383 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002384 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002385 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002386 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2387 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002388 + reader now allows \r characters to be quoted (previously it only allowed
2389 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002390 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002391 + Dialect classes passed to the module are no longer instantiated by
2392 the module before being parsed (the former validation scheme required
2393 this, but the mechanism was unreliable).
2394 + The dialect registry now contains instances of the internal
2395 C-coded dialect type, rather than references to python objects.
2396 + the internal c-coded dialect type is now immutable.
2397 + register_dialect now accepts the same keyword dialect specifications
2398 as the reader and writer, allowing the user to register dialects
2399 without first creating a dialect class.
2400 + a configurable limit to the size of parsed fields has been added -
2401 previously, an unmatched quote character could result in the entire
2402 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002403 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002404 the parser field size limit (returning the former limit). The initial
2405 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002406 + A line_num attribute has been added to the reader object, which tracks
2407 the number of lines read from the source iterator. This is not
2408 the same as the number of records returned, as records can span
2409 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002410 + reader and writer objects were not being registered with the cyclic-GC.
2411 This has been fixed.
2412
Brett Cannone6539c42005-01-08 02:43:53 +00002413- _DummyThread objects in the threading module now delete self.__block that is
2414 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2415 lock primitives tend to be limited in number and thus should not be wasted on
2416 a _DummyThread object. Fixes bug #1089632.
2417
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002418- The imghdr module now detects Exif files.
2419
Raymond Hettinger6065d322004-12-20 23:51:53 +00002420- StringIO.truncate() now correctly adjusts the size attribute.
2421 (Bug #951915).
2422
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002423- locale.py now uses an updated locale alias table (built using
2424 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2425 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002426 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002427
Raymond Hettinger3557f422004-12-07 12:02:02 +00002428- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2429
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002430- the pickle module no longer accepts the deprecated None option in the
2431 args tuple returned by __reduce__().
2432
Brett Cannon84667c02004-12-07 03:25:18 +00002433- optparse now optionally imports gettext. This allows its use in setup.py.
2434
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002435- the pickle module no longer uses the deprecated bin parameter.
2436
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002437- the shelve module no longer uses the deprecated binary parameter.
2438
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002439- the pstats module no longer uses the deprecated ignore() method.
2440
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002441- the filecmp module no longer uses the deprecated use_statcache argument.
2442
Raymond Hettinger664347b2004-12-04 21:21:53 +00002443- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2444 extended or overridden by subclasses. Formerly, the subclassed method would
2445 be ignored by the rest of the module. (Bug #1078905).
2446
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002447- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002448 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002449
Walter Dörwald36733692004-12-22 12:50:50 +00002450- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2451 once when a size argument is given. This prevents a buffer overflow in the
2452 tokenizer with very long source lines.
2453
Barry Warsaw538561e2006-01-01 21:48:54 +00002454- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2455 immediately after creating the object, without any intervening
2456 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002457
Skip Montanaro05885812005-01-16 20:48:27 +00002458- The reconvert.quote function can now emit triple-quoted strings. The
2459 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002460
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002461- ``UserString.MutableString`` now supports negative indices in
2462 ``__setitem__`` and ``__delitem__``
2463
Greg Ward40407942005-03-05 02:53:17 +00002464- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2465 correctly.
2466
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002467- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2468 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2469 character even if the user has passed a size parameter to get a proper
2470 line ending. Remove the special handling of a "\r\n" that has been split
2471 between two lines.
2472
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002473- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2474 about illegal code points. The codec now supports PEP 293 style error
2475 handlers.
2476
Walter Dörwald78a78b02005-09-01 12:04:29 +00002477- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002478 from the input stream, so that the output is a byte string in the correct
2479 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002480
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002481- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2482 considering it exactly like a '*'.
2483
Walter Dörwald007f8df2005-10-09 19:42:27 +00002484- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2485 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002486
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002487- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2488
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002489- Patch #1413711: Certain patterns of differences were making difflib
2490 touch the recursion limit.
2491
Walter Dörwald58917a62006-03-31 15:26:22 +00002492- Bug #947906: An object oriented interface has been added to the calendar
2493 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002494 called as a script (e.g. via ``python -mcalendar``). Localized month and
2495 weekday names can be ouput (even if an exotic encoding is used) using
2496 special classes that use unicode.

2499-----
2500
Neal Norwitz602d3392006-03-31 08:21:40 +00002501- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2502 by using -mieee gcc option.
2503
Martin v. Löwis86d66262006-02-17 08:40:11 +00002504- Patch #1432345: Make python compile on DragonFly.
2505
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002506- Build support for Win64-AMD64 was added.
2507
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002508- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2509
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002510- Patch #881820: look for openpty and forkpty also in libbsd.
2511
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002512- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2513 The zlib module is now builtin on Windows.
2514
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002515- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2516
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002517- Bug #1189330: configure did not correctly determine the necessary
2518 value of LINKCC if python was built with GCC 4.0.
2519
Trent Mick8321b422005-07-26 02:29:21 +00002520- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2521 vulnerability in zlib 1.2.1 and 1.2.2.
2522
Brett Cannon08cd5982005-04-24 22:26:38 +00002523- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2524 flags that change binary compatibility. Changes were also made to
2525 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002526 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002527
Bob Ippolitoed233462005-03-29 13:47:59 +00002528- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2529 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2530 no longer exists). This configure patch makes things right.
2531
Martin v. Löwise2713be2005-03-08 15:03:08 +00002532- Bug #1158607: Build with --disable-unicode again.
2533
Brett Cannon46d96232005-02-16 00:07:19 +00002534- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2535 defined. Discovered as a result of not being able to build on OS X.
2536
Brett Cannon516592f2004-12-07 00:42:59 +00002537- setup.py now uses the directories specified in LDFLAGS using the -L option
2538 and in CPPFLAGS using the -I option for adding library and include
2539 directories, respectively, for compiling extension modules against. This has
2540 led to the core being compiled using the values in CPPFLAGS. It also removes
2541 the need for the special-casing of both DarwinPorts and Fink for darwin since
2542 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2543 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2544 Fink, ``-I/opt/local/include`` for DarwinPorts).
2545
Brett Cannon43802422005-02-10 20:48:03 +00002546- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2547 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2548 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2549 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002551C API
2552-----
2553
Tim Petersc9d78aa2006-03-26 23:27:58 +00002554- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2555 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2556 is obtained via the ``PyObject_`` family, it must be released via the
2557 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2558 always been officially true, but when Python's small-object allocator was
2559 introduced, an attempt was made to cater to a few extension modules
2560 discovered at the time that obtained memory via ``PyObject_New`` but
2561 released it via ``PyMem_DEL``. It's years later, and if such code still
