Neal Norwitzff4b63b2006-08-04 04:50:21 +0000620
621Core and builtins
622-----------------
623
Neal Norwitz24b6f202006-09-05 04:43:56 +0000624- Fix infinite recursion when subclassing long and overriding __hash__.
625
626- Fix concatenation (+=) of long strings.
627
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000628- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000629 compared equal or unequal to a string and a UnicodeDecodeError
630 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000631
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000632 Instead, the equal (==) and unequal (!=) comparison operators will
633 now issue a UnicodeWarning and interpret the two objects as
634 unequal. The UnicodeWarning can be filtered as desired using
635 the warning framework, e.g. silenced completely, turned into an
636 exception, logged, etc.
637
638 Note that compare operators other than equal and unequal will still
639 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000640
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000641- Fix segfault when doing string formatting on subclasses of long.
642
643- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
644 with new-style classes.
645
646- Fix bug related to __len__ functions returning negative values with
647 classic classes.
648
649- Patch #1538606, Fix __index__() clipping. There were some problems
650 discovered with the API and how integers that didn't fit into Py_ssize_t
651 were handled. This patch attempts to provide enough alternatives
652 to effectively use __index__.
653
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000654- Bug #1536021: __hash__ may now return long int; the final hash
655 value is obtained by invoking hash on the long int.
656
Thomas Hellerab1049c2006-08-08 17:37:00 +0000657- Bug #1536786: buffer comparison could emit a RuntimeWarning.
658
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000659- Bug #1535165: fixed a segfault in input() and raw_input() when
660 sys.stdin is closed.
661
Thomas Heller74d36f02006-08-04 18:17:40 +0000662- On Windows, the PyErr_Warn function is now exported from
663 the Python dll again.
664
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000665- Bug #1191458: tracing over for loops now produces a line event
666 on each iteration. Fixing this problem required changing the .pyc
667 magic number. This means that .pyc files generated before 2.5c1
668 will be regenerated.
669
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000670- Bug #1333982: string/number constants were inappropriately stored
671 in the byte code and co_consts even if they were not used, ie
672 immediately popped off the stack.
673
Georg Brandle9462c72006-08-04 18:03:37 +0000674- Fixed a reference-counting problem in property().
675
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000676
677Library
678-------
679
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000680- Fix a bug in the ``compiler`` package that caused invalid code to be
681 generated for generator expressions.
682
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000683- The distutils version has been changed to 2.5.0. The change to
684 keep it programmatically in sync with the Python version running
685 the code (introduced in 2.5b3) has been reverted. It will continue
686 to be maintained manually as static string literal.
687
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000688- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000689 and this cannot be converted to the required C type, an exception is
690 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000691 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000692
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000693- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000694 an exception.
695
Tim Peterscbdd3502006-09-05 01:47:53 +0000696- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000697 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000698 workarounds for clocks with low resolution, to stop the code yielding
699 duplicate UUIDs.
700
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000701- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
702 before raising SystemExit, allowing IDLE to honor quit() and exit().
703
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000704- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
705
Georg Brandl7a1af772006-08-14 21:55:28 +0000706- Patch #1536071: trace.py should now find the full module name of a
707 file correctly even on Windows.
708
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000709- logging's atexit hook now runs even if the rest of the module has
710 already been cleaned up.
711
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000712- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000713
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000714- Bug #1531405, format_exception no longer raises an exception if
715 str(exception) raised an exception.
716
Neil Schemenauer06ded092006-08-04 16:20:30 +0000717- Fix a bug in the ``compiler`` package that caused invalid code to be
718 generated for nested functions.
719
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000720
721Extension Modules
722-----------------

725
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000726- Patch #1511317: don't crash on invalid hostname (alias) info.
727
Georg Brandl3335a7a2006-08-14 21:42:55 +0000728- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
729 raises the correct exceptions.
730
Thomas Heller1ce433e2006-08-14 16:20:04 +0000731- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
732 '-no-stack-protector' compiler flag for OpenBSD has been removed.
733
Thomas Heller86720042006-08-14 11:17:48 +0000734- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
735 uses the _as_parameter_ attribute when objects are passed to foreign
736 function calls. The ctypes version number was changed to 1.0.1.
737
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000738- Bug #1530559, struct.pack raises TypeError where it used to convert.
739 Passing float arguments to struct.pack when integers are expected
740 now triggers a DeprecationWarning.
741
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000742

765
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +0000766- Bug #1535502, build _hashlib on Windows, and use masm assembler
767 code in OpenSSL.
768
Thomas Hellerdb7b4432006-08-04 19:49:31 +0000769- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

Neal Norwitzff4b63b2006-08-04 04:50:21 +0000773
Tim Peters4643c2f2006-08-10 22:45:34 +0000774C API
775-----
776

Neal Norwitza1f10902006-07-12 07:28:29 +0000789
790Core and builtins
791-----------------
792
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000793- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000794 returned a long (see PEP 353).
795
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000796- Bug #1515471: string.replace() accepts character buffers again.
797
Neal Norwitz07aadb12006-07-30 06:55:48 +0000798- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
799 This provides the proper warning for struct.pack().
800 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
801
Neal Norwitz0d62a062006-07-30 06:53:31 +0000802- Patch #1531113: Fix augmented assignment with yield expressions.
803 Also fix a SystemError when trying to assign to yield expressions.
804
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000805- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
806 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
807 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
808 excessive filesystem operations during imports.
809
Tim Petersbc24eee2006-07-27 01:14:53 +0000810- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
811 operations on signed longs that are formally undefined by C.
812 Unfortunately, at least one compiler now cares about that, so complicated
813 the code to make that compiler happy again.
814
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000815- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
816
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000817- Patch #1232023: Stop including current directory in search
818 path on Windows.
819
Neal Norwitze1fdb322006-07-21 05:32:28 +0000820- Fix some potential crashes found with failmalloc.
821
Neal Norwitze7563102006-07-17 01:00:16 +0000822- Fix warnings reported by Klocwork's static analysis tool.
823
Neal Norwitz84be93b2006-07-16 01:50:38 +0000824- Bug #1512814, Fix incorrect lineno's when code within a function
825 had more than 255 blank lines.
826
Georg Brandl9dceedb2006-07-12 15:31:17 +0000827- Patch #1521179: Python now accepts the standard options ``--help`` and
828 ``--version`` as well as ``/?`` on Windows.
829
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000830- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000831 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000832 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000833
Tim Peters112aad32006-07-19 00:03:19 +0000834- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000835 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000836 new ``sys._current_frames()`` returns a dictionary with one entry,
837 mapping the faux "thread id" 0 to the current frame.
838
Ronald Oussoren3075e162006-07-25 20:28:55 +0000839- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000840
Ronald Oussoren3075e162006-07-25 20:28:55 +0000841
Neal Norwitza1f10902006-07-12 07:28:29 +0000842Library
843-------
844
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000845- Correction of patch #1455898: In the mbcs decoder, set final=False
846 for stream decoder, but final=True for the decode function.
847
Georg Brandl07fec3a2006-08-01 18:49:24 +0000848- os.urandom no longer masks unrelated exceptions like SystemExit or
849 KeyboardInterrupt.
850
Tim Peters4643c2f2006-08-10 22:45:34 +0000851- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000852 shutil.copytree on Windows
853
Georg Brandle34ac7c2006-07-30 11:07:23 +0000854- Bug #1002398: The documentation for os.path.sameopenfile now correctly
855 refers to file descriptors, not file objects.
856
Tim Peterscbdd3502006-09-05 01:47:53 +0000857- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000858 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000859 #1513611, and probably others.
860
Georg Brandledd9b0d2006-07-29 09:33:26 +0000861- Bug #1441397: The compiler module now recognizes module and function
862 docstrings correctly as it did in Python 2.4.
863
Tim Peters6f681472006-07-27 23:44:37 +0000864- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
865 lost that tests are sorted by name before being run. This rarely
866 matters for well-written tests, but can create baffling symptoms if
867 side effects from one test to the next affect outcomes. ``DocTestFinder``
868 has been changed to sort the list of tests it returns.
869
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000870- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000871 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000872
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000873- Bug #978833: Really close underlying socket in _socketobject.close.
874
Georg Brandldb232dc2006-08-20 13:15:43 +0000875- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
876 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000877
Georg Brandlcf0c1722006-07-26 07:23:32 +0000878- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
879 to recursive calls and call it with the failing package name.
880
Martin v. Löwis0b483032006-07-25 09:53:12 +0000881- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
882

884 value in the traceback module.
885
Greg Ward48fae7a2006-07-23 16:05:51 +0000886- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
887
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000888- Patch #1524429: Use repr() instead of backticks in Tkinter again.

Brett Cannoncaebe222006-07-18 04:41:36 +0000890- Bug #1520914: Change time.strftime() to accept a zero for any position in its
891 argument tuple. For arguments where zero is illegal, the value is forced to
892 the minimum value that is correct. This is to support an undocumented but
893 common way people used to fill in inconsequential information in the time
894 tuple pre-2.4.
895
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000896- Patch #1220874: Update the binhex module for Mach-O.
897
Barry Warsawb110bad2006-07-21 14:51:07 +0000898- The email package has improved RFC 2231 support, specifically for
899 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
900 (name*0=<blah>) parameter continuations. This may change the types of
901 values returned from email.message.Message.get_param() and friends.
902 Specifically in some cases where non-encoded continuations were used,
903 get_param() used to return a 3-tuple of (None, None, string) whereas now it
904 will just return the string (since non-encoded continuations don't have
905 charset and language parts).
906
907 Also, whereas % values were decoded in all parameter continuations, they are
908 now only decoded in encoded parameter parts.
909
Ronald Oussoren3075e162006-07-25 20:28:55 +0000910- Bug #1517990: IDLE keybindings on MacOS X now work correctly
911
912- Bug #1517996: IDLE now longer shows the default Tk menu when a
913 path browser, class browser or debugger is the frontmost window on MacOS X
914
Barry Warsaw00decd72006-07-27 23:43:15 +0000915- Patch #1520294: Support for getset and member descriptors in types.py,
916 inspect.py, and pydoc.py. Specifically, this allows for querying the type
917 of an object against these built-in types and more importantly, for getting
918 their docstrings printed in the interactive interpreter's help() function.

923
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000924- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
925 a socket operation on a socket with a timeout, the exception will be
926 caught correctly. Previously, the exception was not caught.
927
Thomas Heller1393d6a2006-07-28 21:43:20 +0000928- Patch #1529514: The _ctypes extension is now compiled on more
929 openbsd target platforms.
930
Tim Peters9cab5932006-07-28 00:30:00 +0000931- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
932 a memory leak, affecting pickles and deep copies.
933
Tim Petersbc24eee2006-07-27 01:14:53 +0000934- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

938
Thomas Hellerce049a02006-07-14 17:51:14 +0000939- Patch #1521817: Index range checking on ctypes arrays containing
940 exactly one element enabled again. This allows iterating over these
941 arrays, without the need to check the array size before.
942
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000943- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000944 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000945 /dev/null in certain cases; this is now fixed.
946
Thomas Heller47d7a062006-07-12 08:43:47 +0000947- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
948 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000949
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000950- Because of a misspelled preprocessor symbol, ctypes was always
951 compiled without thread support; this is now fixed.
952
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000953- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
954 methods now allow their database parameter to be None as the
955 sleepycat API allows.
956
Matt Flemingec926502006-07-28 11:27:27 +0000957- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
958 bluetooth API compared with Linux and FreeBSD.
959
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000960Tests
961-----
962
963- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
964 how long the test file should take to play. Now accepts taking 2.93 secs
965 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
966
Georg Brandl4793aa32006-07-28 18:31:39 +0000967- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
968 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
969 run via ``regrtest.py``. Now they do.

974- Bug #1439538: Drop usage of test -e in configure as it is not portable.
975
Ronald Oussoren26cad082006-08-01 21:00:57 +0000976Mac
977---
978
979- PythonLauncher now works correctly when the path to the script contains
980 characters that are treated specially by the shell (such as quotes).
981
982- Bug #1527397: PythonLauncher now launches scripts with the working directory
983 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000984 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000985 expect.

993Core and builtins
994-----------------
995
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000996- Bug #1441486: The literal representation of -(sys.maxint - 1)
997 again evaluates to a int object, not a long.
998
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000999- Bug #1501934: The scope of global variables that are locally assigned
1000 using augmented assignment is now correctly determined.
1001
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001002- Bug #927248: Recursive method-wrapper objects can now safely
1003 be released.
1004
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001005- Bug #1417699: Reject locale-specific decimal point in float()
1006 and atof().
1007
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001008- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1009 omit a default "error" argument for NULL pointer. This allows
1010 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001011
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001012- Bug #1519018: 'as' is now validated properly in import statements.
1013
Neal Norwitz28746ab2006-07-09 22:14:42 +00001014- On 64 bit systems, int literals that use less than 64 bits are
1015 now ints rather than longs.
1016
Neal Norwitzed657552006-07-10 00:04:44 +00001017- Bug #1512814, Fix incorrect lineno's when code at module scope
1018 started after line 256.
1019
Tim Peters32a83612006-07-10 21:08:24 +00001020- New function ``sys._current_frames()`` returns a dict mapping thread
1021 id to topmost thread stack frame. This is for expert use, and is
1022 especially useful for debugging application deadlocks. The functionality
1023 was previously available in Fazal Majid's ``threadframe`` extension
1024 module, but it wasn't possible to do this in a wholly threadsafe way from
1025 an extension.

1042
Thomas Woutersadd19112006-07-05 11:03:49 +00001043- string.Template() now correctly handles tuple-values. Previously,
1044 multi-value tuples would raise an exception and single-value tuples would
1045 be treated as the value they contain, instead.
1046
Martin v. Löwisede77f52006-07-03 13:01:35 +00001047- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1054 degrees and radians.
1055
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001056- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001057 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001058

1061
Martin v. Löwis7596e832006-07-01 15:33:37 +00001062- Bug #1513223: .close() of a _socketobj now releases the underlying

1066 attribute values.
1067
1068- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1069 sgmllib ('[' and ']' were not accepted).
1070
Georg Brandl1be63af2006-06-28 20:23:25 +00001071- Fix a bug in the turtle module's end_fill function.
1072
Brett Cannon53ab5b72006-06-22 16:49:14 +00001073- Bug #1510580: The 'warnings' module improperly required that a Warning
1074 category be either a types.ClassType and a subclass of Warning. The proper
1075 check is just that it is a subclass with Warning as the documentation states.
1076
Georg Brandlad29e632006-06-21 17:45:17 +00001077- The compiler module now correctly compiles the new try-except-finally
1078 statement (bug #1509132).
1079
Neal Norwitz60373cd2006-06-22 06:30:50 +00001080- The wsgiref package is now installed properly on Unix.
1081
Vinay Sajip28e57612006-07-01 10:45:20 +00001082- A bug was fixed in logging.config.fileConfig() which caused a crash on
1083 shutdown when fileConfig() was called multiple times.
1084
Gerhard Häring762fbd32006-07-02 17:48:30 +00001085- The sqlite3 module did cut off data from the SQLite database at the first
1086 null character before sending it to a custom converter. This has been fixed
1087 now.
1088
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001089Extension Modules
1090-----------------
1091
Tim Peters112aad32006-07-19 00:03:19 +00001092- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1093 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1094 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001095
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001096- Assigning None to pointer type fields in ctypes structures possible
1097 overwrote the wrong fields, this is fixed now.
1098
1099- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1100 on non-Windows platforms.
1101
1102- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1103 integer or long, without range checking.
1104
1105- Patch #1517790: It is now possible to use custom objects in the ctypes
1106 foreign function argtypes sequence as long as they provide a from_param
1107 method, no longer is it required that the object is a ctypes type.
1108
1109- The '_ctypes' extension module now works when Python is configured
1110 with the --without-threads option.
1111
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001112- Bug #1513646: os.access on Windows now correctly determines write
1113 access, again.
1114
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001115- Bug #1512695: cPickle.loads could crash if it was interrupted with
1116 a KeyboardInterrupt.
1117
Neal Norwitza12aa882006-07-06 06:45:08 +00001118- Bug #1296433: parsing XML with a non-default encoding and
1119 a CharacterDataHandler could crash the interpreter in pyexpat.
1120

1127
Tim Peters32a83612006-07-10 21:08:24 +00001128- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001129 Previously, the slight difference could cause compilation errors of the
1130 'zlib' module on systems with more than one version of zlib.
1131
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001132- The MSI compileall step was fixed to also support a TARGETDIR
1133 with spaces in it.

Nick Coghlan2d792252006-07-06 13:47:18 +00001150- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1151 documentation for the warnings module.
1152
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001153- Patch #1509163: MS Toolkit Compiler no longer available.

1164-----------------
1165
Georg Brandla56b9152006-06-19 06:35:54 +00001166- Patch #1507676: Error messages returned by invalid abstract object operations
1167 (such as iterating over an integer) have been improved and now include the
1168 type of the offending object to help with debugging.
1169
Brett Cannonea3912b2006-06-13 21:46:41 +00001170- Bug #992017: A classic class that defined a __coerce__() method that returned
1171 its arguments swapped would infinitely recurse and segfault the interpreter.
1172
Neal Norwitz909eb122006-06-12 02:13:21 +00001173- Fix the socket tests so they can be run concurrently.
1174
Neal Norwitzb9845e72006-06-12 02:11:18 +00001175- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001176 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001177
Brett Cannon22565aa2006-06-09 22:31:23 +00001178- Bug #532646: object.__call__() will continue looking for the __call__
1179 attribute on objects until one without one is found. This leads to recursion
1180 when you take a class and set its __call__ attribute to an instance of the
1181 class. Originally fixed for classic classes, but this fix is for new-style.
1182 Removes the infinite_rec_3 crasher.
1183
Georg Brandl24250812006-06-09 18:45:48 +00001184- The string and unicode methods startswith() and endswith() now accept
1185 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1186
Brett Cannonde3b0522006-06-08 17:00:45 +00001187- Buffer objects, at the C level, never used the char buffer
1188 implementation even when the char buffer for the wrapped object was
1189 explicitly requested (originally returned the read or write buffer).
1190 Now a TypeError is raised if the char buffer is not present but is
1191 requested.
1192
Georg Brandlddbaa662006-06-04 21:56:52 +00001193- Patch #1346214: Statements like "if 0: suite" are now again optimized
1194 away like they were in Python 2.4.
1195
Georg Brandlb7c8f542006-05-27 12:30:25 +00001196- Builtin exceptions are now full-blown new-style classes instead of
1197 instances pretending to be classes, which speeds up exception handling
1198 by about 80% in comparison to 2.5a2.
1199
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001200- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1201 Unicode 4.1.
1202
Georg Brandlf4ef1162006-05-26 18:03:31 +00001203- Patch #921466: sys.path_importer_cache is now used to cache valid and
1204 invalid file paths for the built-in import machinery which leads to
1205 fewer open calls on startup.
1206
Tim Peters696cf432006-05-24 21:10:40 +00001207- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1208 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1209 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1210 the number of input digits (it was and remains linear-time for bases
1211 2, 4, 8, 16 and 32).
1212
Tim Petersb713ec22006-05-23 18:45:30 +00001213- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1214 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1215 an integer close to ``sys.maxint``. This was repaired by patch
1216 #1335972, which also gives a nice speedup.
1217
Richard Jonescebbefc2006-05-23 18:28:17 +00001218- Patch #1337051: reduced size of frame objects.
1219
1220- PyErr_NewException now accepts a tuple of base classes as its
1221 "base" parameter.
1222
Richard Jones7c88dcc2006-05-23 10:37:38 +00001223- Patch #876206: function call speedup by retaining allocated frame
1224 objects.
1225
Georg Brandl7b90e162006-05-18 07:01:27 +00001226- Bug #1462152: file() now checks more thoroughly for invalid mode
1227 strings and removes a possible "U" before passing the mode to the
1228 C library function.
1229
Neal Norwitz1004a532006-05-15 07:17:23 +00001230- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1231
Neal Norwitz373f0a72006-05-15 07:04:36 +00001232- Bug #1487966: Fix SystemError with conditional expression in assignment
1233
Martin v. Löwis879768d2006-05-11 13:28:43 +00001234- WindowsError now has two error code attributes: errno, which carries
1235 the error values from errno.h, and winerror, which carries the error
1236 values from winerror.h. Previous versions put the winerror.h values
1237 (from GetLastError()) into the errno attribute.
1238
Martin v. Löwis77736712006-05-04 05:51:03 +00001239- Patch #1475845: Raise IndentationError for unexpected indent.
1240
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001241- Patch #1479181: split open() and file() from being aliases for each other.
1242
Tim Peters44bd9862006-06-01 13:49:23 +00001243- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1244 methods were always silently ignored by dictionaries when comparing keys.
1245 They are now passed through (except when using the C API function
1246 ``PyDict_GetItem()``, whose semantics did not change).
1247
1248- Bug #1456209: In some obscure cases it was possible for a class with a
1249 custom ``__eq__()`` method to confuse dict internals when class instances
1250 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1251 No, you don't have any code that did this ;-)

1254-----------------
1255
Trent Mick960a3f82006-06-28 20:30:41 +00001256- Bug #1295808: expat symbols should be namespaced in pyexpat
1257
1258- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1259
Brett Cannon6ee7d012006-06-08 16:23:04 +00001260- Change binascii.hexlify to accept a read-only buffer instead of only a char
1261 buffer and actually follow its documentation.
1262
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001263- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1264
Nick Coghlanc649ec52006-05-29 12:43:05 +00001265- Patch #1478788 (modified version): The functional extension module has
1266 been renamed to _functools and a functools Python wrapper module added.
1267 This provides a home for additional function related utilities that are
1268 not specifically about functional programming. See PEP 309.
1269
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001270- Patch #1493701: performance enhancements for struct module.
1271
Georg Brandl378d5922006-05-17 14:26:50 +00001272- Patch #1490224: time.altzone is now set correctly on Cygwin.
1273
Georg Brandl8d3342b2006-05-16 07:38:27 +00001274- Patch #1435422: zlib's compress and decompress objects now have a
1275 copy() method.
1276
Andrew MacIntyre92913322006-06-13 15:04:24 +00001277- Patch #1454481: thread stack size is now tunable at runtime for thread
1278 enabled builds on Windows and systems with Posix threads support.
1279
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001280- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1281 (up to the system limit of 32K characters).
1282
1283- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1284 As a result, these functions now raise WindowsError instead of OSError.
1285
Tim Peters7a822da2006-05-25 21:50:17 +00001286- ``time.clock()`` on Win64 should use the high-performance Windows
1287 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1288 Windows platforms).
1289
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001290- Calling Tk_Init twice is refused if the first call failed as that
1291 may deadlock.
1292
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001293- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1294 accept it without potentially using an uninitialized pointer.
1295
1296- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1297 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1298 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001299
Gregory P. Smith372b5832006-06-05 18:48:21 +00001300- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001301 [pybsddb project SF patch number 1466734]
1302
Gregory P. Smith372b5832006-06-05 18:48:21 +00001303- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1304 parameter is supplied. [SF pybsddb bug #1477863]
1305
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001306- bsddb: the __len__ method of a DB object has been fixed to return correct
1307 results. It could previously incorrectly return 0 in some cases.
1308 Fixes SF bug 1493322 (pybsddb bug 1184012).
1309
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001310- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1311 aborts the db transaction safely when a modifier callback fails.
1312 Fixes SF python patch/bug #1408584.
1313
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001314- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001315 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001316 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1317 database calls that would previously deadlock. [SF python bug #775414]
1318
Vinay Sajip28e57612006-07-01 10:45:20 +00001319- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001320
Walter Dörwald4994d952006-06-19 08:07:50 +00001321- Patch #1506645: add Python wrappers for the curses functions
1322 is_term_resized, resize_term and resizeterm.

Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001327- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1328 functions.
1329
Martin v. Löwis3798da02006-06-17 18:44:27 +00001330- Patch #812986: Update turtle output even if not tracing.
1331
Vinay Sajip28e57612006-07-01 10:45:20 +00001332- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001333 Tkinter.BaseWidget.
1334
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001335- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1336
Martin v. Löwis337487e2006-06-17 09:15:14 +00001337- Patch #763580: Add name and value arguments to Tkinter variable
1338 classes.
1339
Georg Brandl83cc0d02006-06-14 08:50:03 +00001340- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1341 mime.types file for determining MIME types.
1342
Georg Brandl2605ca82006-06-14 06:08:31 +00001343- Bug #1339007: Shelf objects now don't raise an exception in their
1344 __del__ method when initialization failed.
1345
Martin v. Löwisd8251432006-06-14 05:21:04 +00001346- Patch #1455898: The MBCS codec now supports the incremental mode for
1347 double-byte encodings.
1348
Tim Peters43898b42006-06-14 04:09:25 +00001349- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1350 guarantee that adjacent triples in the return list always describe
1351 non-adjacent blocks. Previously, a pair of matching blocks could end
1352 up being described by multiple adjacent triples that formed a partition
1353 of the matching pair.
1354
Greg Ward0e0c9f42006-06-11 16:24:11 +00001355- Bug #1498146: fix optparse to handle Unicode strings in option help,
1356 description, and epilog.
1357
Greg Wardd1c797e2006-06-11 14:42:41 +00001358- Bug #1366250: minor optparse documentation error.
1359
Greg Ward7f547402006-06-11 00:40:49 +00001360- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1361 clarify docs.
1362
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001363- The wsgiref package has been added to the standard library.
1364
Nick Coghlan676725d2006-06-08 13:54:49 +00001365- The functions update_wrapper() and wraps() have been added to the functools
1366 module. These make it easier to copy relevant metadata from the original
1367 function when writing wrapper functions.
1368
Tim Petersd6a9eef2006-06-05 01:48:21 +00001369- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1370 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001371
Martin v. Löwis3f767792006-06-04 19:36:28 +00001372- Patch #1359618: Speed up charmap encoder by using a trie structure
1373 for lookup.
1374
Tim Petersd609b1a2006-06-02 23:22:51 +00001375- The functions in the ``pprint`` module now sort dictionaries by key
1376 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1377 if and only if its display required more than one line, although that
1378 wasn't documented. The new behavior increases predictability; e.g.,
1379 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1380
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001381- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1382 (thanks for J. J. Lee).
1383
Georg Brandl2b330372006-05-28 20:23:12 +00001384- Patch #1496206: improve urllib2 handling of passwords with respect to
1385 default HTTP and HTTPS ports.
1386
George Yoshidaf3c65de2006-05-28 16:39:09 +00001387- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1388
Bob Ippolito7298f272006-05-23 18:43:47 +00001389- Patch #1281707: speed up gzip.readline.
1390
Georg Brandlb89316f2006-05-17 15:51:16 +00001391- Patch #1180296: Two new functions were added to the locale module:
1392 format_string() to get the effect of "format % items" but locale-aware,
1393 and currency() to format a monetary number with currency sign.
1394
Georg Brandle3a25832006-05-17 14:56:04 +00001395- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1396 and several features added, such as speed and geometry control.
1397
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001398- Patch #1488881: add support for external file objects in bz2 compressed
1399 tarfiles.
1400
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001401- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1402 stdout arguments, making it possible to redirect input and output
1403 for remote debugging.
1404
1405- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1406 a couple of issues, notably handling of long file names using the
1407 GNU LONGNAME extension.
1408
1409- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1410 new flag when ``name`` is already the name of an option flag.
1411
1412- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1413 package.
1414
1415- Patch #1472854: make the rlcompleter.Completer class usable on non-
1416 UNIX platforms.
1417
1418- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1419
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001420- Bug #1472827: correctly escape newlines and tabs in attribute values in

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001451What's New in Python 2.5 alpha 2?

1453
1454*Release date: 27-APR-2006*
1455
1456Core and builtins
1457-----------------
1458
Thomas Heller1b046642006-04-18 18:51:06 +00001459- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1460 by converting these apis from macros into exported functions again:
1461
1462 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1463 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1464 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1465 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1466 PyRun_String Py_CompileString
1467
Martin v. Löwis45294a92006-04-18 06:24:08 +00001468- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1469
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001470- All uses of PyStructSequence_InitType have been changed to initialize
1471 the type objects only once, even if the interpreter is initialized
1472 multiple times.
1473
Neal Norwitz61546162006-04-14 05:20:28 +00001474- Bug #1454485, array.array('u') could crash the interpreter. This was
1475 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1476 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1477
1478- Py_UNICODE is unsigned. It was always documented as unsigned, but
1479 due to a bug had a signed value in previous versions.
1480
Tim Peters3a5e8b12006-04-11 01:44:07 +00001481- Patch #837242: ``id()`` of any Python object always gives a positive
1482 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1483 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001484 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001485 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001486
Tim Peters3a5e8b12006-04-11 01:44:07 +00001487 def __hash__(self):
1488 return id(self) # WRONG
1489
1490 because a hash result must be a (short) Python int but it was always
1491 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001492 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001493 was always usable as a hash value before this patch. That's no longer
1494 necessarily so.
1495
1496- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001497 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001498 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001499 #1454844)
1500
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001501- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1502 involving generators that have paused outside of any ``try`` or ``with``
1503 blocks. (In 2.5a1, a paused generator that was part of a reference
1504 cycle could not be garbage collected, regardless of whether it was
1505 paused in a ``try`` or ``with`` block.)

1519 the cachesize parameter.
1520
1521- Bug #1149413: bsddb.*open() no longer raises an exception when using
1522 a temporary db (file=None) with the 'n' flag to truncate on open.
1523
1524- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1525 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001526
Armin Rigoa9017c32006-04-19 11:50:27 +00001527- Patch #1062014: AF_UNIX sockets under Linux have a special
1528 abstract namespace that is now fully supported.

1532
Peter Astrand7d1d4362006-07-14 14:04:45 +00001533- Bug #1223937: subprocess.CalledProcessError reports the exit status
1534 of the process using the returncode attribute, instead of
1535 abusing errno.
1536
Tim Peters711bf302006-04-25 03:31:36 +00001537- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1538 a doctest to be skipped (the code is not run, and the expected output
1539 or exception is ignored).
1540
Nick Coghlanda2268f2006-04-24 04:37:15 +00001541- Fixed contextlib.nested to cope with exceptions being raised and
1542 caught inside exit handlers.
1543
Greg Wardab05edc2006-04-23 03:47:58 +00001544- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1545 hex, octal, or binary; add ``append_const`` action; keep going if
1546 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1547 added ``epilog`` for better help generation).
1548
Tim Peters21fbd572006-04-21 21:18:10 +00001549- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1550 called from a thread spawned as a side effect of importing a module.
1551
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001552- The pydoc module now supports documenting packages contained in
1553 .zip or .egg files.
1554
1555- The pkgutil module now has several new utility functions, such
1556 as ``walk_packages()`` to support working with packages that are either
1557 in the filesystem or zip files.
1558
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001559- The mailbox module can now modify and delete messages from
1560 mailboxes, in addition to simply reading them. Thanks to Gregory
1561 K. Johnson for writing the code, and to the 2005 Google Summer of
1562 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001563

Anthony Baxtere29002c2006-04-12 12:07:31 +00001573- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1574 Windows. Bug #1469163.
1575
Phillip J. Eby47032112006-04-11 01:07:43 +00001576- The warnings, linecache, inspect, traceback, site, and doctest modules

1586
Skip Montanaro262fb922006-04-21 02:31:07 +00001587- The pstats.Stats class accepts an optional stream keyword argument to
1588 direct output to an alternate file-like object.
1589
Anthony Baxter51bcb682006-04-05 14:51:42 +00001590Build
1591-----
1592
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001593- The Makefile now has a reindent target, which runs reindent.py on
1594 the library.
1595
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001596- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001599
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001600- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1601 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001602 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001603 CXX from --with-cxx-main, see description in README.
1604
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001605- Patch #1429775: Link extension modules with the shared libpython.
1606
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001607- Fixed a libffi build problem on MIPS systems.
1608
Tim Peters8931ff12006-05-13 23:28:20 +00001609- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1610 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1611 and "%zu" for unsigned integers of type ``size_t``.
1612
Anthony Baxter51bcb682006-04-05 14:51:42 +00001613Tests
1614-----
1615
Nick Coghlanda2268f2006-04-24 04:37:15 +00001616- test_contextlib now checks contextlib.nested can cope with exceptions
1617 being raised and caught inside exit handlers.
1618
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001619- test_cmd_line now checks operation of the -m and -c command switches
1620
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001621- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1622 it separately and by hand. It also wasn't cleaning up its changes to
1623 the current Decimal context.
1624
Thomas Woutersabd08882006-04-26 15:53:30 +00001625- regrtest.py now has a -M option to run tests that test the new limits of
1626 containers, on 64-bit architectures. Running these tests is only sensible
1627 on 64-bit machines with more than two gigabytes of memory. The argument
1628 passed is the maximum amount of memory for the tests to use.
1629
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001630Tools

1637-------------
1638
Tim Petersb06d28c2006-05-12 01:57:59 +00001639- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1640
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001641- PEP 343: Added Context Types section to the library reference
1642 and attempted to bring other PEP 343 related documentation into
1643 line with the implementation and/or python-dev discussions.
1644
Tim Peters8dc73d22006-04-24 02:03:16 +00001645- Bug #1337990: clarified that ``doctest`` does not support examples
1646 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001649What's New in Python 2.5 alpha 1?
1650=================================
1651
Anthony Baxterebed3f62006-04-03 15:03:44 +00001652*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001653
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001654Core and builtins
1655-----------------
1656
Nick Coghlan43832302006-04-23 17:04:07 +00001657- PEP 338: -m command line switch now delegates to runpy.run_module
1658 allowing it to support modules in packages and zipfiles
1659
Martin v. Löwisc661b882006-04-20 04:54:23 +00001660- On Windows, .DLL is not an accepted file name extension for
1661 extension modules anymore; extensions are only found if they
1662 end in .PYD.
1663
Martin v. Löwisea62d252006-04-03 10:56:49 +00001664- Bug #1421664: sys.stderr.encoding is now set to the same value as
1665 sys.stdout.encoding.
1666
Neal Norwitz92e212f2006-04-03 04:48:37 +00001667- __import__ accepts keyword arguments.
1668
Georg Brandlccadf842006-03-31 18:54:53 +00001669- Patch #1460496: round() now accepts keyword arguments.
1670
Anthony Baxter262c00a2006-03-30 10:53:17 +00001671- Fixed bug #1459029 - unicode reprs were double-escaped.
1672
Hye-Shik Changd478f342006-03-23 12:32:36 +00001673- Patch #1396919: The system scope threads are reenabled on FreeBSD
1674 5.4 and later versions.
1675
Neal Norwitze98ccf62006-03-23 05:39:47 +00001676- Bug #1115379: Compiling a Unicode string with an encoding declaration
1677 now gives a SyntaxError.
1678
Georg Brandlabd1ff82006-03-18 07:59:59 +00001679- Previously, Python code had no easy way to access the contents of a
1680 cell object. Now, a ``cell_contents`` attribute has been added
1681 (closes patch #1170323).
1682
Tim Peterscf79aac2006-03-16 01:14:46 +00001683- Patch #1123430: Python's small-object allocator now returns an arena to
1684 the system ``free()`` when all memory within an arena becomes unused
1685 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1686 freed. Some applications will see a drop in virtual memory size now,
1687 especially long-running applications that, from time to time, temporarily
1688 use a large number of small objects. Note that when Python returns an
1689 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001690 platform C library will in turn return that memory to the operating system.
1691 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001692 appears to be effective at least on Microsoft C and gcc-based systems.
1693 Thanks to Evan Jones for hard work and patience.
1694
Georg Brandl533ff6f2006-03-08 18:09:27 +00001695- Patch #1434038: property() now uses the getter's docstring if there is
1696 no "doc" argument given. This makes it possible to legitimately use
1697 property() as a decorator to produce a read-only property.
1698
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001699- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1700 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1701 of requiring an int or long in slicing and a few other contexts, enabling
1702 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1703
Neal Norwitz995acdf2006-03-07 05:01:00 +00001704- Fixed various bugs reported by Coverity's Prevent tool.
1705
Brett Cannonbf364092006-03-01 04:25:17 +00001706- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1707 new exception base class, BaseException, which has a new message attribute.
1708 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1709 Raising a string exception now raises a DeprecationWarning.
1710
Thomas Woutersfb609f42006-02-28 16:37:25 +00001711- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1712 explicitly relative, using 'from .module import name' to mean 'from the same
1713 package as this module is in. Imports without dots still default to the
1714 old relative-then-absolute, unless 'from __future__ import
1715 absolute_import' is used.
1716
Brett Cannona7446e32006-02-27 23:39:10 +00001717- Properly check if 'warnings' raises an exception (usually when a filter set
1718 to "error" is triggered) when raising a warning for raising string
1719 exceptions.
1720
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001721- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001722 The name was removed from Include/code.h.
1723
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001724- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001725
Guido van Rossum1968ad32006-02-25 22:38:04 +00001726- Patch 1433928:
1727 - The copy module now "copies" function objects (as atomic objects).
1728 - dict.__getitem__ now looks for a __missing__ hook before raising
1729 KeyError.
1730
Tim Peters84ef21c2006-02-28 20:39:06 +00001731- PEP 343: with statement implemented. Needs ``from __future__ import
1732 with_statement``. Use of 'with' as a variable will generate a warning.
1733 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001734 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001735 The following objects have __context__ methods:
1736 - The built-in file type.
1737 - The thread.LockType type.
1738 - The following types defined by the threading module:
1739 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1740 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001741
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001742- Fix the encodings package codec search function to only search
1743 inside its own package. Fixes problem reported in patch #1433198.
1744
1745 Note: Codec packages should implement and register their own
1746 codec search function. PEP 100 has the details.
1747
Tim Peters9ea89d22006-06-04 03:26:02 +00001748- PEP 353: Using ``Py_ssize_t`` as the index type.
1749
1750- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1751 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1752 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1753 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1754 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001755
Neal Norwitzfc76d632006-01-10 06:03:13 +00001756- Patch #1400181, fix unicode string formatting to not use the locale.
1757 This is how string objects work. u'%f' could use , instead of .
1758 for the decimal point. Now both strings and unicode always use periods.
1759
Neal Norwitz671b9e32006-01-09 07:07:12 +00001760- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1761 configure would break checking curses.h.
1762
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001763- Bug #959576: The pwd module is now builtin. This allows Python to be
1764 built on UNIX platforms without $HOME set.
1765
Neal Norwitzc10978f2005-12-19 06:07:16 +00001766- Bug #1072182, fix some potential problems if characters are signed.
1767
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001768- Bug #889500, fix line number on SyntaxWarning for global declarations.
1769
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001770- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1771
Neal Norwitze7214a12005-12-18 05:03:17 +00001772- Support for converting hex strings to floats no longer works.
1773 This was not portable. float('0x3') now raises a ValueError.
1774
Barry Warsaw2a38a862005-12-18 01:27:35 +00001775- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001776 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001777 is now displayed in interactive prompt banner.
1778
Georg Brandlfa166682005-12-17 21:45:17 +00001779- Implementation of PEP 341 - Unification of try/except and try/finally.
1780 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001781 one try statement instead of two nested ones. Patch #1355913.

Hye-Shik Chang835b2432005-12-17 04:38:31 +00001783- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1784 now encodes backslash correctly.
1785
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001786- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1787
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001788- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001789 and long longs.
1790
Neal Norwitz67715f02005-11-09 06:59:35 +00001791- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001792 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001793 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001794
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001795- Replaced most Unicode charmap codecs with new ones using the
1796 new Unicode translate string feature in the builtin charmap
1797 codec; the codecs were created from the mapping tables available
1798 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1799 encodings now include a mapping for the Apple logo)
1800
Tim Peterse3547fd2005-12-16 23:13:57 +00001801- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001802
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001803- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001804
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001805- A new AST parser implementation was completed. The abstract
1806 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001807 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001808
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001809- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001810 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1811
Neal Norwitz708e51a2005-10-03 04:48:15 +00001812- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1813
Neal Norwitz11bd1192005-10-03 00:54:56 +00001814- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1815 Provide a warning when a directory is passed on the command line.
1816
Neal Norwitz40d37812005-10-02 01:48:49 +00001817- Fix segfault with invalid coding.
1818
1819- SF bug #772896: unknown encoding results in MemoryError.
1820
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001821- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001822 supported a __len__() method which evaluated to False when the iterator
1823 was empty.
1824
Guido van Rossum630db602005-09-20 18:49:54 +00001825- On 64-bit platforms, when __len__() returns a value that cannot be
1826 represented as a C int, raise OverflowError.
1827
Skip Montanarof8948ca2005-09-19 03:54:46 +00001828- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001829 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001830
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001831- SF bug #893549: parsing keyword arguments was broken with a few format
1832 codes.
1833
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001834- Changes donated by Elemental Security to make it work on AIX 5.3
1835 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1836 bug #105470: test_pwd fails on 64bit system (Opteron).
1837
Guido van Rossum539c6622005-09-14 17:49:54 +00001838- Changes donated by Elemental Security to make it work on HP-UX 11 on
1839 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1840
Georg Brandl4550b8d2005-08-26 06:43:52 +00001841- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001842 (fixes bug #1119418).
1843
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001844- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1845
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001846- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1847 exceptions that cause a function to exit.
1848
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001849- The implementation of set() and frozenset() was revised to use its
1850 own internal data structure. Memory consumption is reduced by 1/3
1851 and there are modest speed-ups as well. The API is unchanged.
1852
Tim Petersde7990b2005-07-17 23:45:23 +00001853- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1854
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001855- SF bug #1229429: PyObject_CallMethod failed to decrement some
1856 reference counts in some error exit cases.
1857
Tim Petersecc6e6a2005-07-10 22:30:55 +00001858- SF bug #1185883: Python's small-object memory allocator took over
1859 a block managed by the platform C library whenever a realloc specified
1860 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001861 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001862 portable way to copy data from the C-managed block into Python's
1863 small-object space without risking a memory fault. Python's small-object
1864 realloc now leaves such blocks under the control of the platform C
1865 realloc.
1866
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001867- SF bug #1232517: An overflow error was not detected properly when
1868 attempting to convert a large float to an int in os.utime().
1869
Raymond Hettinger3296e692005-06-29 23:29:56 +00001870- SF bug #1224347: hex longs now print with lowercase letters just
1871 like their int counterparts.
1872
Michael W. Hudson188d4362005-06-20 16:52:57 +00001873- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1874 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1875 interpreter states; back out that fix and do a better job (see
1876 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1877 for a longer write-up of the problem).
1878
Michael W. Hudsondf888462005-06-03 14:41:55 +00001879- SF patch #1180995: marshal now uses a binary format by default when
1880 serializing floats.
1881
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001882- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1883 the routines that promise to produce IEEE 754 binary representations
1884 of floats now simply copy bytes around.
1885
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001886- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1887 278.
1888
Brett Cannonc3647ac2005-04-26 03:45:26 +00001889- patch #1109424: int, long, float, complex, and unicode now check for the
1890 proper magic slot for type conversions when subclassed. Previously the
1891 magic slot was ignored during conversion. Semantics now match the way
1892 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001893 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001894 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001895 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001896
Barry Warsawc8d907c2005-04-19 23:43:40 +00001897- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1898 NULL, now raise an AttributeError when attempting to set or delete the
1899 attribute. Previously a TypeError was raised, but this was inconsistent
1900 with the equivalent pure-Python implementation.
1901
Michael W. Hudson774479c2005-04-18 08:46:17 +00001902- It is now safe to call PyGILState_Release() before
1903 PyEval_InitThreads() (note that if there is reason to believe there
1904 are multiple threads around you still must call PyEval_InitThreads()
1905 before using the Python API; this fix is for extension modules that
1906 have no way of knowing if Python is multi-threaded yet).
1907
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001908- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1909 disabled caused a crash.
1910
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001911- Bug #1165306: instancemethod_new allowed the creation of a method
1912 with im_class == im_self == NULL, which caused a crash when called.
1913
Tim Petersecc6e6a2005-07-10 22:30:55 +00001914- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001915 fixes the crash seen in bug #1165761
1916
Raymond Hettinger96229b12005-03-11 06:49:40 +00001917- Added two new builtins, any() and all().
1918
Brett Cannon409d8f22005-03-05 06:47:57 +00001919- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001920 (e.g., ``class C(): pass`` is no longer a syntax error).
1921 Patch #1176012 added support to the 'parser' module and 'compiler' package
1922 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001923
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001924- Patch #1115086: Support PY_LONGLONG in structmember.
1925
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001926- Bug #1155938: new style classes did not check that __init__() was
1927 returning None.
1928
Tim Petersecc6e6a2005-07-10 22:30:55 +00001929- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001930 ('\') with a specific error message.
1931
Martin v. Löwisff232d72005-03-03 09:24:38 +00001932- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1933
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001934- Bug #1124295: the __name__ attribute of file objects was
1935 inadvertently made inaccessible in restricted mode.
1936
Tim Petersecc6e6a2005-07-10 22:30:55 +00001937- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001938 an ferror() call.
1939
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001940- min() and max() now support key= arguments with the same meaning as in
1941 list.sort().
1942
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001943- The peephole optimizer now performs simple constant folding in expressions:
1944 (2+3) --> (5).
1945
Raymond Hettingera422c342005-01-11 03:03:27 +00001946- set and frozenset objects can now be marshalled. SF #1098985.
1947
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001948- Bug #1077106: Poor argument checking could cause memory corruption
1949 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001950
Jeremy Hyltonab630502005-02-04 18:44:06 +00001951- The parser did not complain about future statements in illegal
1952 positions. It once again reports a syntax error if a future
1953 statement occurs after anything other than a doc string.
1954
Neil Schemenauercf52c072005-08-12 17:34:58 +00001955- Change the %s format specifier for str objects so that it returns a
1956 unicode instance if the argument is not an instance of basestring and
1957 calling __str__ on the argument returns a unicode instance.
1958
Tim Petersf4e69282006-02-27 17:15:31 +00001959- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1960 current thread state when the auto-GIL-state machinery knows about
1961 it (since the thread state is being deleted, continuing to remember it
1962 can't help, but can hurt if another thread happens to get created with
1963 the same thread id).
1964
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001965Extension Modules
1966-----------------
1967

Tim Petersc9d78aa2006-03-26 23:27:58 +00001980 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001981 util, whatsound, whrandom, zmod
1982
1983- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1984
1985- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001986 is deprecated. The undocumented re.engine variable no longer exists.
1987
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001988- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1989 SS2 (single-shift 2) escape sequences correctly.
1990
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001991- The unicodedata module was updated to the 4.1 version of the Unicode
1992 database. The 3.2 version is still available as unicodedata.db_3_2_0
1993 for applications that require this specific version (such as IDNA).
1994
Neal Norwitzb62c4332006-03-04 18:35:47 +00001995- The timing module is no longer built by default. It was deprecated
1996 in PEP 4 in Python 2.0 or earlier.
1997
Guido van Rossum1968ad32006-02-25 22:38:04 +00001998- Patch 1433928: Added a new type, defaultdict, to the collections module.
1999 This uses the new __missing__ hook behavior added to dict (see above).
2000
Georg Brandldbd83392006-02-20 09:42:33 +00002001- Bug #854823: socketmodule now builds on Sun platforms even when
2002 INET_ADDRSTRLEN is not defined.
2003
Georg Brandlf4f44152006-02-18 22:29:33 +00002004- Patch #1393157: os.startfile() now has an optional argument to specify
2005 a "command verb" to invoke on the file.
2006
Neal Norwitz082b2df2006-02-07 07:04:46 +00002007- Bug #876637, prevent stack corruption when socket descriptor
2008 is larger than FD_SETSIZE.
2009
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00002010- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
2011 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
2012 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
2013
Martin v. Löwis57a34e82006-02-04 19:12:37 +00002014- Patch #1422385: The nis module now supports access to domains other
2015 than the system default domain.
2016
Martin v. Löwis14694662006-02-03 12:54:16 +00002017- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2018 are reported, the limit on path name lengths is removed, and stat reports
2019 WindowsError now (instead of OSError).
2020
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002021- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

2096 the request code argument, which results in more C-like behaviour
2097 for large or negative values.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002155- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2156 been renamed to have only a single underscore prefix. This was done to
2157 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002158
Nick Coghlan43832302006-04-23 17:04:07 +00002159- PEP 338: new module runpy defines a run_module function to support
2160 executing modules which provide access to source code or a code object
2161 via the PEP 302 import mechanisms.
2162
Anthony Baxter93f5b932006-04-03 08:05:07 +00002163- The email module's parsedate_tz function now sets the daylight savings
2164 flag to -1 (unknown) since it can't tell from the date whether it should

2171 in attribute values.
2172
Anthony Baxterc51ee692006-04-01 00:57:31 +00002173- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002174 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002175 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002176 module will not be built.
2177
Tim Petersc17976e2006-04-01 00:26:53 +00002178- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2179 aren't officially supported here, and trying to use them will probably
2180 raise an exception some day. But dicts have been allowed, and "mostly
2181 worked", so support for them won't go away without warning.
2182
Georg Brandl338ef7d2006-03-31 18:42:16 +00002183- Bug #1445068: getpass.getpass() can now be given an explicit stream
2184 argument to specify where to write the prompt.
2185

Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002194- Queue.Queue objects now support .task_done() and .join() methods
2195 to make it easier to monitor when daemon threads have completed
2196 processing all enqueued tasks. Patch #1455676.
2197

2201
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002202- email 4.0 package now integrated. This is largely the same as the email 3.0
2203 package that was included in Python 2.3, except that PEP 8 module names are
2204 now used (e.g. mail.message instead of email.Message). The MIME classes
2205 have been moved to a subpackage (e.g. email.mime.text instead of
2206 email.MIMEText). The old names are still supported for now. Several
2207 deprecated Message methods have been removed and lots of bugs have been
2208 fixed. More details can be found in the email package documentation.
2209
Walter Dörwald40108c92006-03-27 08:15:44 +00002210- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2211 (a subclass of tuple) that provides incremental decoders and encoders
2212 (a way to use stateful codecs without the stream API). Python functions
2213 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2214 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2215 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002216
Walter Dörwald067db482006-03-15 22:17:27 +00002217- Patch #1359365: Calling next() on a closed StringIO.String object raises
2218 a ValueError instead of a StopIteration now (like file and cString.String do).
2219 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2220 called before (like file and StringIO.StringIO do).

Martin v. Löwis3e865952006-01-24 15:51:21 +00002270 specifications, raises IOErrors when proxies for unsupported protocols
2271 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00002294 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2295 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2296 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2297 Ronald L. Rivest offered this advice for Python:
2298
2299 "The consensus of researchers in this area (at least as
2300 expressed at the NIST Hash Function Workshop 10/31/05),
2301 is that SHA-256 is a good choice for the time being, but
2302 that research should continue, and other alternatives may
2303 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002304
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002305- Added a subset of Fredrik Lundh's ElementTree package. Available

2358 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002359 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002360

2380
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00002381- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
2382 to W3C name (404 -> 'Not Found'). RFE #1216944.
2383
Georg Brandl9e43acf2005-07-04 17:16:07 +00002384- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2385 as this can cause problems with apps closing all file descriptors.

2398 Bug #1224621.
2399
Raymond Hettinger68c04532005-06-10 11:05:19 +00002400- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002401 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002402 the generate_tokens() function now accepts a callable argument that
2403 terminates by raising StopIteration.
2404
Georg Brandl9166e1a2005-06-04 09:20:03 +00002405- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2406
Georg Brandl268e61c2005-06-03 14:28:50 +00002407- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2408 component of the path.
2409
Skip Montanaro174dd222005-05-14 20:54:16 +00002410- Patch #1120353: The xmlrpclib module provides better, more transparent,
2411 support for datetime.{datetime,date,time} objects. With use_datetime set
2412 to True, applications shouldn't have to fiddle with the DateTime wrapper
2413 class at all.
2414
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002415- distutils.commands.upload was added to support uploading distribution
2416 files to PyPI.
2417
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002418- distutils.commands.register now encodes the data as UTF-8 before posting
2419 them to PyPI.
2420
Raymond Hettinger267b8682005-03-27 10:47:39 +00002421- decimal operator and comparison methods now return NotImplemented
2422 instead of raising a TypeError when interacting with other types. This
2423 allows other classes to implement __radd__ style methods and have them
2424 work as expected.
2425
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002426- Bug #1163325: Decimal infinities failed to hash. Attempting to
2427 hash a NaN raised an InvalidOperation instead of a TypeError.
2428
Tim Petersecc6e6a2005-07-10 22:30:55 +00002429- Patch #918101: Add tarfile open mode r|* for auto-detection of the

2463
Guido van Rossumd0641422005-02-03 15:01:24 +00002464- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2465 disables recursive traversal through instance attributes, which can
2466 be exploited in various ways.
2467
Tim Peterse3547fd2005-12-16 23:13:57 +00002468- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002469 flags on the HTTP listening socket.
2470
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002471- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2472 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2473
Fred Drakefbdeaad2006-07-29 16:56:15 +00002474- Patches #893642, #1039083: add allow_none, encoding arguments to
2475 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002476
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002477- Bug #1110478: Revert os.environ.update to do putenv again.
2478
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002479- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2480
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002481- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2482
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002483- Enhancements to the csv module:
2484
2485 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002486 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002487 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002488 + Dialect parameter parsing has been re-implemented to improve error
2489 reporting.
2490 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2491 dictates.
2492 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002493 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002494 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002495 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2496 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002497 + reader now allows \r characters to be quoted (previously it only allowed
2498 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002499 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002500 + Dialect classes passed to the module are no longer instantiated by
2501 the module before being parsed (the former validation scheme required
2502 this, but the mechanism was unreliable).
2503 + The dialect registry now contains instances of the internal
2504 C-coded dialect type, rather than references to python objects.
2505 + the internal c-coded dialect type is now immutable.
2506 + register_dialect now accepts the same keyword dialect specifications
2507 as the reader and writer, allowing the user to register dialects
2508 without first creating a dialect class.
2509 + a configurable limit to the size of parsed fields has been added -
2510 previously, an unmatched quote character could result in the entire
2511 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002512 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002513 the parser field size limit (returning the former limit). The initial
2514 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002515 + A line_num attribute has been added to the reader object, which tracks
2516 the number of lines read from the source iterator. This is not
2517 the same as the number of records returned, as records can span
2518 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002519 + reader and writer objects were not being registered with the cyclic-GC.
2520 This has been fixed.
2521
Brett Cannone6539c42005-01-08 02:43:53 +00002522- _DummyThread objects in the threading module now delete self.__block that is
2523 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2524 lock primitives tend to be limited in number and thus should not be wasted on
2525 a _DummyThread object. Fixes bug #1089632.
2526
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002527- The imghdr module now detects Exif files.
2528
Raymond Hettinger6065d322004-12-20 23:51:53 +00002529- StringIO.truncate() now correctly adjusts the size attribute.
2530 (Bug #951915).
2531
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002532- locale.py now uses an updated locale alias table (built using
2533 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2534 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002535 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002536
Raymond Hettinger3557f422004-12-07 12:02:02 +00002537- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2538
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002539- the pickle module no longer accepts the deprecated None option in the
2540 args tuple returned by __reduce__().
2541
Brett Cannon84667c02004-12-07 03:25:18 +00002542- optparse now optionally imports gettext. This allows its use in setup.py.
2543
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002544- the pickle module no longer uses the deprecated bin parameter.
2545
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002546- the shelve module no longer uses the deprecated binary parameter.
2547
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002548- the pstats module no longer uses the deprecated ignore() method.
2549
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002550- the filecmp module no longer uses the deprecated use_statcache argument.
2551
Raymond Hettinger664347b2004-12-04 21:21:53 +00002552- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2553 extended or overridden by subclasses. Formerly, the subclassed method would
2554 be ignored by the rest of the module. (Bug #1078905).
2555
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002556- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002557 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002558
Walter Dörwald36733692004-12-22 12:50:50 +00002559- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2560 once when a size argument is given. This prevents a buffer overflow in the
2561 tokenizer with very long source lines.
2562
Barry Warsaw538561e2006-01-01 21:48:54 +00002563- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2564 immediately after creating the object, without any intervening
2565 ``.decompress()`` calls.

Skip Montanaro05885812005-01-16 20:48:27 +00002567- The reconvert.quote function can now emit triple-quoted strings. The
2568 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002569
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002570- ``UserString.MutableString`` now supports negative indices in
2571 ``__setitem__`` and ``__delitem__``
2572
Greg Ward40407942005-03-05 02:53:17 +00002573- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2574 correctly.
2575
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002576- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2577 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2578 character even if the user has passed a size parameter to get a proper
2579 line ending. Remove the special handling of a "\r\n" that has been split
2580 between two lines.
2581
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002582- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2583 about illegal code points. The codec now supports PEP 293 style error
2584 handlers.
2585
Walter Dörwald78a78b02005-09-01 12:04:29 +00002586- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002587 from the input stream, so that the output is a byte string in the correct
2588 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002589
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002590- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2591 considering it exactly like a '*'.
2592
Walter Dörwald007f8df2005-10-09 19:42:27 +00002593- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2594 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002595
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002596- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2597
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002598- Patch #1413711: Certain patterns of differences were making difflib
2599 touch the recursion limit.
2600
Walter Dörwald58917a62006-03-31 15:26:22 +00002601- Bug #947906: An object oriented interface has been added to the calendar
2602 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002603 called as a script (e.g. via ``python -mcalendar``). Localized month and
2604 weekday names can be ouput (even if an exotic encoding is used) using
2605 special classes that use unicode.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002607Build
2608-----
2609
Neal Norwitz602d3392006-03-31 08:21:40 +00002610- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2611 by using -mieee gcc option.
2612

2614
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002615- Build support for Win64-AMD64 was added.
2616
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002617- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2618
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002619- Patch #881820: look for openpty and forkpty also in libbsd.
2620
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002621- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2622 The zlib module is now builtin on Windows.
2623
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002624- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2625
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002626- Bug #1189330: configure did not correctly determine the necessary
2627 value of LINKCC if python was built with GCC 4.0.
2628
Trent Mick8321b422005-07-26 02:29:21 +00002629- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2630 vulnerability in zlib 1.2.1 and 1.2.2.
2631
Brett Cannon08cd5982005-04-24 22:26:38 +00002632- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2633 flags that change binary compatibility. Changes were also made to
2634 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002635 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002636
Bob Ippolitoed233462005-03-29 13:47:59 +00002637- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2638 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2639 no longer exists). This configure patch makes things right.
2640
Martin v. Löwise2713be2005-03-08 15:03:08 +00002641- Bug #1158607: Build with --disable-unicode again.
2642
Brett Cannon46d96232005-02-16 00:07:19 +00002643- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2644 defined. Discovered as a result of not being able to build on OS X.
2645
Brett Cannon516592f2004-12-07 00:42:59 +00002646- setup.py now uses the directories specified in LDFLAGS using the -L option
2647 and in CPPFLAGS using the -I option for adding library and include
2648 directories, respectively, for compiling extension modules against. This has
2649 led to the core being compiled using the values in CPPFLAGS. It also removes
2650 the need for the special-casing of both DarwinPorts and Fink for darwin since
2651 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2652 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2653 Fink, ``-I/opt/local/include`` for DarwinPorts).
2654
Brett Cannon43802422005-02-10 20:48:03 +00002655- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2656 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2657 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2658 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002660C API
2661-----
2662
Tim Petersc9d78aa2006-03-26 23:27:58 +00002663- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2664 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2665 is obtained via the ``PyObject_`` family, it must be released via the
2666 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2667 always been officially true, but when Python's small-object allocator was
2668 introduced, an attempt was made to cater to a few extension modules
2669 discovered at the time that obtained memory via ``PyObject_New`` but
2670 released it via ``PyMem_DEL``. It's years later, and if such code still
2671 exists it will fail now (probably with segfaults, but calling wrong
2672 low-level memory management functions can yield many symptoms).
2673
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002674- Added a C API for set and frozenset objects.
2675
Raymond Hettinger66517482004-12-03 11:45:13 +00002676- Removed PyRange_New().
2677
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002678- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2679 mapping argument now. This string is used as a mapping table. Byte values
2680 greater than the length of the string and 0xFFFE are treated as undefined
2681 mappings.

2686
Martin v. Löwis4d394df2005-01-23 09:19:22 +00002687- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002688
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002689- Patch #1276356: New resource "urlfetch" is implemented. This enables
2690 even impatient people to run tests that require remote files.

2740 directory for syntax highlighting in Vim. Vim directory was added and placed
2741 vimrc to it (was previous up a level).
2742
Georg Brandl56897312005-08-24 18:32:30 +00002743- Added two new files to Tools/scripts: pysource.py, which recursively
2744 finds Python source files, and findnocoding.py, which finds Python
2745 source files that need an encoding declaration.
