Guido van Rossumc69ac252006-08-10 18:09:25 +0000605What's New in Python 2.5 release candidate 1?
606=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000607
Anthony Baxterb4096662006-08-16 03:42:26 +0000608*Release date: 17-AUG-2006*
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000609
610Core and builtins
611-----------------
612
Neal Norwitz24b6f202006-09-05 04:43:56 +0000613- Fix infinite recursion when subclassing long and overriding __hash__.
614
615- Fix concatenation (+=) of long strings.
616
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000617- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000618 compared equal or unequal to a string and a UnicodeDecodeError
619 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000620
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000621 Instead, the equal (==) and unequal (!=) comparison operators will
622 now issue a UnicodeWarning and interpret the two objects as
623 unequal. The UnicodeWarning can be filtered as desired using
624 the warning framework, e.g. silenced completely, turned into an
625 exception, logged, etc.
626
627 Note that compare operators other than equal and unequal will still
628 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000629
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000630- Fix segfault when doing string formatting on subclasses of long.
631
632- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
633 with new-style classes.
634
635- Fix bug related to __len__ functions returning negative values with
636 classic classes.
637
638- Patch #1538606, Fix __index__() clipping. There were some problems
639 discovered with the API and how integers that didn't fit into Py_ssize_t
640 were handled. This patch attempts to provide enough alternatives
641 to effectively use __index__.
642
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000643- Bug #1536021: __hash__ may now return long int; the final hash
644 value is obtained by invoking hash on the long int.
645
Thomas Hellerab1049c2006-08-08 17:37:00 +0000646- Bug #1536786: buffer comparison could emit a RuntimeWarning.
647
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000648- Bug #1535165: fixed a segfault in input() and raw_input() when
649 sys.stdin is closed.
650
Thomas Heller74d36f02006-08-04 18:17:40 +0000651- On Windows, the PyErr_Warn function is now exported from
652 the Python dll again.
653
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000654- Bug #1191458: tracing over for loops now produces a line event
655 on each iteration. Fixing this problem required changing the .pyc
656 magic number. This means that .pyc files generated before 2.5c1
657 will be regenerated.
658
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000659- Bug #1333982: string/number constants were inappropriately stored
660 in the byte code and co_consts even if they were not used, ie
661 immediately popped off the stack.
662
Georg Brandle9462c72006-08-04 18:03:37 +0000663- Fixed a reference-counting problem in property().
664
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000665
666Library
667-------
668
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000669- Fix a bug in the ``compiler`` package that caused invalid code to be
670 generated for generator expressions.
671
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000672- The distutils version has been changed to 2.5.0. The change to
673 keep it programmatically in sync with the Python version running
674 the code (introduced in 2.5b3) has been reverted. It will continue
675 to be maintained manually as static string literal.
676
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000677- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000678 and this cannot be converted to the required C type, an exception is
679 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000680 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000681
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000682- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000683 an exception.
684
Tim Peterscbdd3502006-09-05 01:47:53 +0000685- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000686 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000687 workarounds for clocks with low resolution, to stop the code yielding
688 duplicate UUIDs.
689
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000690- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
691 before raising SystemExit, allowing IDLE to honor quit() and exit().
692
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000693- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
694
Georg Brandl7a1af772006-08-14 21:55:28 +0000695- Patch #1536071: trace.py should now find the full module name of a
696 file correctly even on Windows.
697
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000698- logging's atexit hook now runs even if the rest of the module has
699 already been cleaned up.
700
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000701- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000702
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000703- Bug #1531405, format_exception no longer raises an exception if
704 str(exception) raised an exception.
705
Neil Schemenauer06ded092006-08-04 16:20:30 +0000706- Fix a bug in the ``compiler`` package that caused invalid code to be
707 generated for nested functions.
708
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000709
710Extension Modules
711-----------------
712

714
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000715- Patch #1511317: don't crash on invalid hostname (alias) info.
716
Georg Brandl3335a7a2006-08-14 21:42:55 +0000717- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
718 raises the correct exceptions.
719
Thomas Heller1ce433e2006-08-14 16:20:04 +0000720- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
721 '-no-stack-protector' compiler flag for OpenBSD has been removed.
722
Thomas Heller86720042006-08-14 11:17:48 +0000723- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
724 uses the _as_parameter_ attribute when objects are passed to foreign
725 function calls. The ctypes version number was changed to 1.0.1.
726
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000727- Bug #1530559, struct.pack raises TypeError where it used to convert.
728 Passing float arguments to struct.pack when integers are expected
729 now triggers a DeprecationWarning.
730
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000731
732Tests

Andrew MacIntyre16ee33a2006-08-06 12:37:03 +0000742- test_threading now skips testing alternate thread stack sizes on
743 platforms that don't support changing thread stack size.
744
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000745
Georg Brandl212b5872006-08-05 06:10:54 +0000746Documentation

751
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000752Build
753-----
754
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +0000755- Bug #1535502, build _hashlib on Windows, and use masm assembler
756 code in OpenSSL.
757
Thomas Hellerdb7b4432006-08-04 19:49:31 +0000758- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

Neal Norwitzff4b63b2006-08-04 04:50:21 +0000762
Tim Peters4643c2f2006-08-10 22:45:34 +0000763C API
764-----
765
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000766- New API for Unicode rich comparisons: PyUnicode_RichCompare()
767
Tim Peters4643c2f2006-08-10 22:45:34 +0000768- Bug #1069160. Internal correctness changes were made to

Fred Drake53912162006-07-29 13:22:49 +0000774What's New in Python 2.5 beta 3?
775================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000776
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000777*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000778
779Core and builtins
780-----------------
781
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000782- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000783 returned a long (see PEP 353).
784
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000785- Bug #1515471: string.replace() accepts character buffers again.
786
Neal Norwitz07aadb12006-07-30 06:55:48 +0000787- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
788 This provides the proper warning for struct.pack().
789 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
790
Neal Norwitz0d62a062006-07-30 06:53:31 +0000791- Patch #1531113: Fix augmented assignment with yield expressions.
792 Also fix a SystemError when trying to assign to yield expressions.
793
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000794- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
795 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
796 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
797 excessive filesystem operations during imports.
798
Tim Petersbc24eee2006-07-27 01:14:53 +0000799- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
800 operations on signed longs that are formally undefined by C.
801 Unfortunately, at least one compiler now cares about that, so complicated
802 the code to make that compiler happy again.
803
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000804- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
805
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000806- Patch #1232023: Stop including current directory in search
807 path on Windows.
808
Neal Norwitze1fdb322006-07-21 05:32:28 +0000809- Fix some potential crashes found with failmalloc.
810
Neal Norwitze7563102006-07-17 01:00:16 +0000811- Fix warnings reported by Klocwork's static analysis tool.
812
Neal Norwitz84be93b2006-07-16 01:50:38 +0000813- Bug #1512814, Fix incorrect lineno's when code within a function
814 had more than 255 blank lines.
815
Georg Brandl9dceedb2006-07-12 15:31:17 +0000816- Patch #1521179: Python now accepts the standard options ``--help`` and
817 ``--version`` as well as ``/?`` on Windows.
818
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000819- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000820 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000821 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000822
Tim Peters112aad32006-07-19 00:03:19 +0000823- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000824 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000825 new ``sys._current_frames()`` returns a dictionary with one entry,
826 mapping the faux "thread id" 0 to the current frame.
827
Ronald Oussoren3075e162006-07-25 20:28:55 +0000828- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000829
Ronald Oussoren3075e162006-07-25 20:28:55 +0000830
Neal Norwitza1f10902006-07-12 07:28:29 +0000831Library
832-------
833
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000834- Correction of patch #1455898: In the mbcs decoder, set final=False
835 for stream decoder, but final=True for the decode function.
836
Georg Brandl07fec3a2006-08-01 18:49:24 +0000837- os.urandom no longer masks unrelated exceptions like SystemExit or
838 KeyboardInterrupt.
839
Tim Peters4643c2f2006-08-10 22:45:34 +0000840- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000841 shutil.copytree on Windows
842
Georg Brandle34ac7c2006-07-30 11:07:23 +0000843- Bug #1002398: The documentation for os.path.sameopenfile now correctly
844 refers to file descriptors, not file objects.
845
Tim Peterscbdd3502006-09-05 01:47:53 +0000846- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000847 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000848 #1513611, and probably others.
849
Georg Brandledd9b0d2006-07-29 09:33:26 +0000850- Bug #1441397: The compiler module now recognizes module and function
851 docstrings correctly as it did in Python 2.4.
852
Tim Peters6f681472006-07-27 23:44:37 +0000853- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
854 lost that tests are sorted by name before being run. This rarely
855 matters for well-written tests, but can create baffling symptoms if
856 side effects from one test to the next affect outcomes. ``DocTestFinder``
857 has been changed to sort the list of tests it returns.
858
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000859- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000860 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000861
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000862- Bug #978833: Really close underlying socket in _socketobject.close.
863
Georg Brandldb232dc2006-08-20 13:15:43 +0000864- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
865 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000866
Georg Brandlcf0c1722006-07-26 07:23:32 +0000867- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
868 to recursive calls and call it with the failing package name.
869
Martin v. Löwis0b483032006-07-25 09:53:12 +0000870- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
871
Georg Brandlc13c34c2006-07-24 14:09:56 +0000872- Patch #1515343: Fix printing of deprecated string exceptions with a
873 value in the traceback module.
874
Greg Ward48fae7a2006-07-23 16:05:51 +0000875- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
876
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000877- Patch #1524429: Use repr() instead of backticks in Tkinter again.
878
Brett Cannoncaebe222006-07-18 04:41:36 +0000879- Bug #1520914: Change time.strftime() to accept a zero for any position in its
880 argument tuple. For arguments where zero is illegal, the value is forced to
881 the minimum value that is correct. This is to support an undocumented but
882 common way people used to fill in inconsequential information in the time
883 tuple pre-2.4.
884
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000885- Patch #1220874: Update the binhex module for Mach-O.
886
Barry Warsawb110bad2006-07-21 14:51:07 +0000887- The email package has improved RFC 2231 support, specifically for
888 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
889 (name*0=<blah>) parameter continuations. This may change the types of
890 values returned from email.message.Message.get_param() and friends.
891 Specifically in some cases where non-encoded continuations were used,
892 get_param() used to return a 3-tuple of (None, None, string) whereas now it
893 will just return the string (since non-encoded continuations don't have
894 charset and language parts).
895
896 Also, whereas % values were decoded in all parameter continuations, they are
897 now only decoded in encoded parameter parts.
898
Ronald Oussoren3075e162006-07-25 20:28:55 +0000899- Bug #1517990: IDLE keybindings on MacOS X now work correctly
900
901- Bug #1517996: IDLE now longer shows the default Tk menu when a
902 path browser, class browser or debugger is the frontmost window on MacOS X
903
Barry Warsaw00decd72006-07-27 23:43:15 +0000904- Patch #1520294: Support for getset and member descriptors in types.py,
905 inspect.py, and pydoc.py. Specifically, this allows for querying the type
906 of an object against these built-in types and more importantly, for getting
907 their docstrings printed in the interactive interpreter's help() function.

912
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000913- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
914 a socket operation on a socket with a timeout, the exception will be
915 caught correctly. Previously, the exception was not caught.
916
Thomas Heller1393d6a2006-07-28 21:43:20 +0000917- Patch #1529514: The _ctypes extension is now compiled on more
918 openbsd target platforms.
919
Tim Peters9cab5932006-07-28 00:30:00 +0000920- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
921 a memory leak, affecting pickles and deep copies.
922
Tim Petersbc24eee2006-07-27 01:14:53 +0000923- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

927
Thomas Hellerce049a02006-07-14 17:51:14 +0000928- Patch #1521817: Index range checking on ctypes arrays containing
929 exactly one element enabled again. This allows iterating over these
930 arrays, without the need to check the array size before.
931
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000932- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000933 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000934 /dev/null in certain cases; this is now fixed.
935
Thomas Heller47d7a062006-07-12 08:43:47 +0000936- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
937 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000938
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000939- Because of a misspelled preprocessor symbol, ctypes was always
940 compiled without thread support; this is now fixed.
941
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000942- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
943 methods now allow their database parameter to be None as the
944 sleepycat API allows.
945
Matt Flemingec926502006-07-28 11:27:27 +0000946- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
947 bluetooth API compared with Linux and FreeBSD.
948
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000949Tests
950-----
951
952- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
953 how long the test file should take to play. Now accepts taking 2.93 secs
954 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
955
Georg Brandl4793aa32006-07-28 18:31:39 +0000956- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
957 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
958 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +0000959
Martin v. Löwis0907f4d2006-07-30 14:09:47 +0000960Build
961-----
962
963- Bug #1439538: Drop usage of test -e in configure as it is not portable.
964
Ronald Oussoren26cad082006-08-01 21:00:57 +0000965Mac
966---
967
968- PythonLauncher now works correctly when the path to the script contains
969 characters that are treated specially by the shell (such as quotes).
970
971- Bug #1527397: PythonLauncher now launches scripts with the working directory
972 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000973 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000974 expect.

982Core and builtins
983-----------------
984
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000985- Bug #1441486: The literal representation of -(sys.maxint - 1)
986 again evaluates to a int object, not a long.
987
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000988- Bug #1501934: The scope of global variables that are locally assigned
989 using augmented assignment is now correctly determined.
990
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000991- Bug #927248: Recursive method-wrapper objects can now safely
992 be released.
993
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000994- Bug #1417699: Reject locale-specific decimal point in float()
995 and atof().
996
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000997- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
998 omit a default "error" argument for NULL pointer. This allows
999 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001000
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001001- Bug #1519018: 'as' is now validated properly in import statements.
1002
Neal Norwitz28746ab2006-07-09 22:14:42 +00001003- On 64 bit systems, int literals that use less than 64 bits are
1004 now ints rather than longs.
1005
Neal Norwitzed657552006-07-10 00:04:44 +00001006- Bug #1512814, Fix incorrect lineno's when code at module scope
1007 started after line 256.
1008
Tim Peters32a83612006-07-10 21:08:24 +00001009- New function ``sys._current_frames()`` returns a dict mapping thread
1010 id to topmost thread stack frame. This is for expert use, and is
1011 especially useful for debugging application deadlocks. The functionality
1012 was previously available in Fazal Majid's ``threadframe`` extension
1013 module, but it wasn't possible to do this in a wholly threadsafe way from
1014 an extension.
1015

1023
Tim Peters32a83612006-07-10 21:08:24 +00001024- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001025 environment variable to be set in order to the SDK environment
1026 for finding the compiler, include files, etc.

1031
Thomas Woutersadd19112006-07-05 11:03:49 +00001032- string.Template() now correctly handles tuple-values. Previously,
1033 multi-value tuples would raise an exception and single-value tuples would
1034 be treated as the value they contain, instead.
1035
Martin v. Löwisede77f52006-07-03 13:01:35 +00001036- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1037 even if some data are received.
1038
Martin v. Löwis45482392006-07-03 12:28:58 +00001039- Bug #1267547: Put proper recursive setup.py call into the
1040 spec file generated by bdist_rpm.

Martin v. Löwis2b88f632006-07-03 10:19:49 +00001042- Bug #1514693: Update turtle's heading when switching between
1043 degrees and radians.
1044
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001045- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001046 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001047
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001048- Bug #1514703: Only setup canvas window in turtle when the canvas
1049 is created.
1050
Martin v. Löwis7596e832006-07-01 15:33:37 +00001051- Bug #1513223: .close() of a _socketobj now releases the underlying

1055 attribute values.
1056
1057- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1058 sgmllib ('[' and ']' were not accepted).
1059
Georg Brandl1be63af2006-06-28 20:23:25 +00001060- Fix a bug in the turtle module's end_fill function.
1061
Brett Cannon53ab5b72006-06-22 16:49:14 +00001062- Bug #1510580: The 'warnings' module improperly required that a Warning
1063 category be either a types.ClassType and a subclass of Warning. The proper
1064 check is just that it is a subclass with Warning as the documentation states.
1065
Georg Brandlad29e632006-06-21 17:45:17 +00001066- The compiler module now correctly compiles the new try-except-finally
1067 statement (bug #1509132).
1068
Neal Norwitz60373cd2006-06-22 06:30:50 +00001069- The wsgiref package is now installed properly on Unix.
1070

1072 shutdown when fileConfig() was called multiple times.
1073
Gerhard Häring762fbd32006-07-02 17:48:30 +00001074- The sqlite3 module did cut off data from the SQLite database at the first
1075 null character before sending it to a custom converter. This has been fixed
1076 now.
1077
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001078Extension Modules
1079-----------------
1080
Tim Peters112aad32006-07-19 00:03:19 +00001081- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1082 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1083 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001084
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001085- Assigning None to pointer type fields in ctypes structures possible
1086 overwrote the wrong fields, this is fixed now.
1087
1088- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1089 on non-Windows platforms.
1090
1091- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1092 integer or long, without range checking.
1093
1094- Patch #1517790: It is now possible to use custom objects in the ctypes
1095 foreign function argtypes sequence as long as they provide a from_param
1096 method, no longer is it required that the object is a ctypes type.
1097
1098- The '_ctypes' extension module now works when Python is configured
1099 with the --without-threads option.
1100
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001101- Bug #1513646: os.access on Windows now correctly determines write
1102 access, again.
1103
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001104- Bug #1512695: cPickle.loads could crash if it was interrupted with
1105 a KeyboardInterrupt.
1106
Neal Norwitza12aa882006-07-06 06:45:08 +00001107- Bug #1296433: parsing XML with a non-default encoding and
1108 a CharacterDataHandler could crash the interpreter in pyexpat.
1109
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001110- Patch #1516912: improve Modules support for OpenVMS.

1116
Tim Peters32a83612006-07-10 21:08:24 +00001117- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001118 Previously, the slight difference could cause compilation errors of the
1119 'zlib' module on systems with more than one version of zlib.
1120
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001121- The MSI compileall step was fixed to also support a TARGETDIR
1122 with spaces in it.
1123
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001124- Bug #1517388: sqlite3.dll is now installed on Windows independent

1133- Call os.waitpid() at the end of tests that spawn child processes in order
1134 to minimize resources (zombies).
1135
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001136Documentation
1137-------------
1138
Nick Coghlan2d792252006-07-06 13:47:18 +00001139- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1140 documentation for the warnings module.
1141
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001142- Patch #1509163: MS Toolkit Compiler no longer available.

1153-----------------
1154
Georg Brandla56b9152006-06-19 06:35:54 +00001155- Patch #1507676: Error messages returned by invalid abstract object operations
1156 (such as iterating over an integer) have been improved and now include the
1157 type of the offending object to help with debugging.
1158
Brett Cannonea3912b2006-06-13 21:46:41 +00001159- Bug #992017: A classic class that defined a __coerce__() method that returned
1160 its arguments swapped would infinitely recurse and segfault the interpreter.
1161
Neal Norwitz909eb122006-06-12 02:13:21 +00001162- Fix the socket tests so they can be run concurrently.
1163
Neal Norwitzb9845e72006-06-12 02:11:18 +00001164- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001165 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001166
Brett Cannon22565aa2006-06-09 22:31:23 +00001167- Bug #532646: object.__call__() will continue looking for the __call__
1168 attribute on objects until one without one is found. This leads to recursion
1169 when you take a class and set its __call__ attribute to an instance of the
1170 class. Originally fixed for classic classes, but this fix is for new-style.
1171 Removes the infinite_rec_3 crasher.
1172
Georg Brandl24250812006-06-09 18:45:48 +00001173- The string and unicode methods startswith() and endswith() now accept
1174 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1175
Brett Cannonde3b0522006-06-08 17:00:45 +00001176- Buffer objects, at the C level, never used the char buffer
1177 implementation even when the char buffer for the wrapped object was
1178 explicitly requested (originally returned the read or write buffer).
1179 Now a TypeError is raised if the char buffer is not present but is
1180 requested.
1181
Georg Brandlddbaa662006-06-04 21:56:52 +00001182- Patch #1346214: Statements like "if 0: suite" are now again optimized
1183 away like they were in Python 2.4.
1184
Georg Brandlb7c8f542006-05-27 12:30:25 +00001185- Builtin exceptions are now full-blown new-style classes instead of
1186 instances pretending to be classes, which speeds up exception handling
1187 by about 80% in comparison to 2.5a2.
1188
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001189- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1190 Unicode 4.1.
1191
Georg Brandlf4ef1162006-05-26 18:03:31 +00001192- Patch #921466: sys.path_importer_cache is now used to cache valid and
1193 invalid file paths for the built-in import machinery which leads to
1194 fewer open calls on startup.
1195
Tim Peters696cf432006-05-24 21:10:40 +00001196- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1197 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1198 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1199 the number of input digits (it was and remains linear-time for bases
1200 2, 4, 8, 16 and 32).
1201
Tim Petersb713ec22006-05-23 18:45:30 +00001202- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1203 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1204 an integer close to ``sys.maxint``. This was repaired by patch
1205 #1335972, which also gives a nice speedup.
1206
Richard Jonescebbefc2006-05-23 18:28:17 +00001207- Patch #1337051: reduced size of frame objects.
1208
1209- PyErr_NewException now accepts a tuple of base classes as its
1210 "base" parameter.
1211
Richard Jones7c88dcc2006-05-23 10:37:38 +00001212- Patch #876206: function call speedup by retaining allocated frame
1213 objects.
1214
Georg Brandl7b90e162006-05-18 07:01:27 +00001215- Bug #1462152: file() now checks more thoroughly for invalid mode
1216 strings and removes a possible "U" before passing the mode to the
1217 C library function.
1218
Neal Norwitz1004a532006-05-15 07:17:23 +00001219- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1220
Neal Norwitz373f0a72006-05-15 07:04:36 +00001221- Bug #1487966: Fix SystemError with conditional expression in assignment
1222
Martin v. Löwis879768d2006-05-11 13:28:43 +00001223- WindowsError now has two error code attributes: errno, which carries
1224 the error values from errno.h, and winerror, which carries the error
1225 values from winerror.h. Previous versions put the winerror.h values
1226 (from GetLastError()) into the errno attribute.
1227
Martin v. Löwis77736712006-05-04 05:51:03 +00001228- Patch #1475845: Raise IndentationError for unexpected indent.
1229
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001230- Patch #1479181: split open() and file() from being aliases for each other.
1231
Tim Peters44bd9862006-06-01 13:49:23 +00001232- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1233 methods were always silently ignored by dictionaries when comparing keys.
1234 They are now passed through (except when using the C API function
1235 ``PyDict_GetItem()``, whose semantics did not change).
1236
1237- Bug #1456209: In some obscure cases it was possible for a class with a
1238 custom ``__eq__()`` method to confuse dict internals when class instances
1239 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1240 No, you don't have any code that did this ;-)

1243-----------------
1244
Trent Mick960a3f82006-06-28 20:30:41 +00001245- Bug #1295808: expat symbols should be namespaced in pyexpat
1246
1247- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1248
Brett Cannon6ee7d012006-06-08 16:23:04 +00001249- Change binascii.hexlify to accept a read-only buffer instead of only a char
1250 buffer and actually follow its documentation.
1251
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001252- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1253
Nick Coghlanc649ec52006-05-29 12:43:05 +00001254- Patch #1478788 (modified version): The functional extension module has
1255 been renamed to _functools and a functools Python wrapper module added.
1256 This provides a home for additional function related utilities that are
1257 not specifically about functional programming. See PEP 309.
1258
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001259- Patch #1493701: performance enhancements for struct module.
1260
Georg Brandl378d5922006-05-17 14:26:50 +00001261- Patch #1490224: time.altzone is now set correctly on Cygwin.
1262
Georg Brandl8d3342b2006-05-16 07:38:27 +00001263- Patch #1435422: zlib's compress and decompress objects now have a
1264 copy() method.
1265
Andrew MacIntyre92913322006-06-13 15:04:24 +00001266- Patch #1454481: thread stack size is now tunable at runtime for thread
1267 enabled builds on Windows and systems with Posix threads support.
1268
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001269- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1270 (up to the system limit of 32K characters).
1271
1272- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1273 As a result, these functions now raise WindowsError instead of OSError.
1274
Tim Peters7a822da2006-05-25 21:50:17 +00001275- ``time.clock()`` on Win64 should use the high-performance Windows
1276 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1277 Windows platforms).
1278
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001279- Calling Tk_Init twice is refused if the first call failed as that
1280 may deadlock.
1281
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001282- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1283 accept it without potentially using an uninitialized pointer.
1284
1285- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1286 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1287 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001288
Gregory P. Smith372b5832006-06-05 18:48:21 +00001289- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001290 [pybsddb project SF patch number 1466734]
1291
Gregory P. Smith372b5832006-06-05 18:48:21 +00001292- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1293 parameter is supplied. [SF pybsddb bug #1477863]
1294
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001295- bsddb: the __len__ method of a DB object has been fixed to return correct
1296 results. It could previously incorrectly return 0 in some cases.
1297 Fixes SF bug 1493322 (pybsddb bug 1184012).
1298
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001299- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1300 aborts the db transaction safely when a modifier callback fails.
1301 Fixes SF python patch/bug #1408584.
1302
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001303- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001304 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001305 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1306 database calls that would previously deadlock. [SF python bug #775414]
1307
Vinay Sajip28e57612006-07-01 10:45:20 +00001308- Patch #1446489: add support for the ZIP64 extensions to zipfile.

1323
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001324- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1325
Martin v. Löwis337487e2006-06-17 09:15:14 +00001326- Patch #763580: Add name and value arguments to Tkinter variable
1327 classes.
1328
Georg Brandl83cc0d02006-06-14 08:50:03 +00001329- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1330 mime.types file for determining MIME types.
1331
Georg Brandl2605ca82006-06-14 06:08:31 +00001332- Bug #1339007: Shelf objects now don't raise an exception in their
1333 __del__ method when initialization failed.
1334
Martin v. Löwisd8251432006-06-14 05:21:04 +00001335- Patch #1455898: The MBCS codec now supports the incremental mode for
1336 double-byte encodings.
1337
Tim Peters43898b42006-06-14 04:09:25 +00001338- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1339 guarantee that adjacent triples in the return list always describe
1340 non-adjacent blocks. Previously, a pair of matching blocks could end
1341 up being described by multiple adjacent triples that formed a partition
1342 of the matching pair.
1343
Greg Ward0e0c9f42006-06-11 16:24:11 +00001344- Bug #1498146: fix optparse to handle Unicode strings in option help,
1345 description, and epilog.
1346
Greg Wardd1c797e2006-06-11 14:42:41 +00001347- Bug #1366250: minor optparse documentation error.
1348
Greg Ward7f547402006-06-11 00:40:49 +00001349- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1350 clarify docs.
1351
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001352- The wsgiref package has been added to the standard library.
1353
Nick Coghlan676725d2006-06-08 13:54:49 +00001354- The functions update_wrapper() and wraps() have been added to the functools
1355 module. These make it easier to copy relevant metadata from the original
1356 function when writing wrapper functions.
1357
Tim Petersd6a9eef2006-06-05 01:48:21 +00001358- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1359 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001360
Martin v. Löwis3f767792006-06-04 19:36:28 +00001361- Patch #1359618: Speed up charmap encoder by using a trie structure
1362 for lookup.
1363
Tim Petersd609b1a2006-06-02 23:22:51 +00001364- The functions in the ``pprint`` module now sort dictionaries by key
1365 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1366 if and only if its display required more than one line, although that
1367 wasn't documented. The new behavior increases predictability; e.g.,
1368 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1369
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001370- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1371 (thanks for J. J. Lee).
1372
Georg Brandl2b330372006-05-28 20:23:12 +00001373- Patch #1496206: improve urllib2 handling of passwords with respect to
1374 default HTTP and HTTPS ports.
1375
George Yoshidaf3c65de2006-05-28 16:39:09 +00001376- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1377
Bob Ippolito7298f272006-05-23 18:43:47 +00001378- Patch #1281707: speed up gzip.readline.
1379
Georg Brandlb89316f2006-05-17 15:51:16 +00001380- Patch #1180296: Two new functions were added to the locale module:
1381 format_string() to get the effect of "format % items" but locale-aware,
1382 and currency() to format a monetary number with currency sign.
1383
Georg Brandle3a25832006-05-17 14:56:04 +00001384- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1385 and several features added, such as speed and geometry control.
1386
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001387- Patch #1488881: add support for external file objects in bz2 compressed
1388 tarfiles.
1389
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001390- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1391 stdout arguments, making it possible to redirect input and output
1392 for remote debugging.
1393
1394- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1395 a couple of issues, notably handling of long file names using the
1396 GNU LONGNAME extension.
1397
1398- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1399 new flag when ``name`` is already the name of an option flag.
1400
1401- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1402 package.
1403
1404- Patch #1472854: make the rlcompleter.Completer class usable on non-
1405 UNIX platforms.
1406
1407- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1408
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001409- Bug #1472827: correctly escape newlines and tabs in attribute values in

1442
1443*Release date: 27-APR-2006*
1444
1445Core and builtins
1446-----------------
1447
Thomas Heller1b046642006-04-18 18:51:06 +00001448- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1449 by converting these apis from macros into exported functions again:
1450
1451 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1452 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1453 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1454 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1455 PyRun_String Py_CompileString
1456
Martin v. Löwis45294a92006-04-18 06:24:08 +00001457- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1458
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001459- All uses of PyStructSequence_InitType have been changed to initialize
1460 the type objects only once, even if the interpreter is initialized
1461 multiple times.
1462
Neal Norwitz61546162006-04-14 05:20:28 +00001463- Bug #1454485, array.array('u') could crash the interpreter. This was
1464 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1465 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1466
1467- Py_UNICODE is unsigned. It was always documented as unsigned, but
1468 due to a bug had a signed value in previous versions.
1469
Tim Peters3a5e8b12006-04-11 01:44:07 +00001470- Patch #837242: ``id()`` of any Python object always gives a positive
1471 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1472 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001473 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001474 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001475
Tim Peters3a5e8b12006-04-11 01:44:07 +00001476 def __hash__(self):
1477 return id(self) # WRONG
1478
1479 because a hash result must be a (short) Python int but it was always
1480 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001481 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001482 was always usable as a hash value before this patch. That's no longer
1483 necessarily so.
1484
1485- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001486 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001487 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001488 #1454844)
1489
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001490- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1491 involving generators that have paused outside of any ``try`` or ``with``
1492 blocks. (In 2.5a1, a paused generator that was part of a reference
1493 cycle could not be garbage collected, regardless of whether it was
1494 paused in a ``try`` or ``with`` block.)

Peter Astrand7d1d4362006-07-14 14:04:45 +00001522- Bug #1223937: subprocess.CalledProcessError reports the exit status
1523 of the process using the returncode attribute, instead of
1524 abusing errno.
1525
Tim Peters711bf302006-04-25 03:31:36 +00001526- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1527 a doctest to be skipped (the code is not run, and the expected output
1528 or exception is ignored).
1529
Nick Coghlanda2268f2006-04-24 04:37:15 +00001530- Fixed contextlib.nested to cope with exceptions being raised and
1531 caught inside exit handlers.

1534 hex, octal, or binary; add ``append_const`` action; keep going if
1535 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1536 added ``epilog`` for better help generation).
1537
Tim Peters21fbd572006-04-21 21:18:10 +00001538- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when

1540
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001541- The pydoc module now supports documenting packages contained in
1542 .zip or .egg files.
1543
1544- The pkgutil module now has several new utility functions, such
1545 as ``walk_packages()`` to support working with packages that are either
1546 in the filesystem or zip files.
1547
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001548- The mailbox module can now modify and delete messages from
1549 mailboxes, in addition to simply reading them. Thanks to Gregory
1550 K. Johnson for writing the code, and to the 2005 Google Summer of
1551 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001552

Anthony Baxtere29002c2006-04-12 12:07:31 +00001562- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1563 Windows. Bug #1469163.
1564
Phillip J. Eby47032112006-04-11 01:07:43 +00001565- The warnings, linecache, inspect, traceback, site, and doctest modules

Skip Montanaro262fb922006-04-21 02:31:07 +00001576- The pstats.Stats class accepts an optional stream keyword argument to
1577 direct output to an alternate file-like object.
1578
Anthony Baxter51bcb682006-04-05 14:51:42 +00001579Build
1580-----
1581
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001582- The Makefile now has a reindent target, which runs reindent.py on
1583 the library.
1584
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001585- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001588
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001589- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1590 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001591 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001592 CXX from --with-cxx-main, see description in README.
1593
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001594- Patch #1429775: Link extension modules with the shared libpython.
1595
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001596- Fixed a libffi build problem on MIPS systems.
1597
Tim Peters8931ff12006-05-13 23:28:20 +00001598- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1599 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1600 and "%zu" for unsigned integers of type ``size_t``.
1601
Anthony Baxter51bcb682006-04-05 14:51:42 +00001602Tests
1603-----
1604
Nick Coghlanda2268f2006-04-24 04:37:15 +00001605- test_contextlib now checks contextlib.nested can cope with exceptions
1606 being raised and caught inside exit handlers.
1607
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001608- test_cmd_line now checks operation of the -m and -c command switches
1609
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001610- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1611 it separately and by hand. It also wasn't cleaning up its changes to
1612 the current Decimal context.
1613
Thomas Woutersabd08882006-04-26 15:53:30 +00001614- regrtest.py now has a -M option to run tests that test the new limits of
1615 containers, on 64-bit architectures. Running these tests is only sensible
1616 on 64-bit machines with more than two gigabytes of memory. The argument
1617 passed is the maximum amount of memory for the tests to use.
1618
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001619Tools
1620-----

Anthony Baxter51bcb682006-04-05 14:51:42 +00001625Documentation
1626-------------
1627
Tim Petersb06d28c2006-05-12 01:57:59 +00001628- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1629
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001630- PEP 343: Added Context Types section to the library reference
1631 and attempted to bring other PEP 343 related documentation into
1632 line with the implementation and/or python-dev discussions.
1633
Tim Peters8dc73d22006-04-24 02:03:16 +00001634- Bug #1337990: clarified that ``doctest`` does not support examples
1635 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001638What's New in Python 2.5 alpha 1?
1639=================================
1640
Anthony Baxterebed3f62006-04-03 15:03:44 +00001641*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001642
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001643Core and builtins
1644-----------------
1645
Nick Coghlan43832302006-04-23 17:04:07 +00001646- PEP 338: -m command line switch now delegates to runpy.run_module
1647 allowing it to support modules in packages and zipfiles
1648
Martin v. Löwisc661b882006-04-20 04:54:23 +00001649- On Windows, .DLL is not an accepted file name extension for
1650 extension modules anymore; extensions are only found if they
1651 end in .PYD.
1652
Martin v. Löwisea62d252006-04-03 10:56:49 +00001653- Bug #1421664: sys.stderr.encoding is now set to the same value as
1654 sys.stdout.encoding.
1655
Neal Norwitz92e212f2006-04-03 04:48:37 +00001656- __import__ accepts keyword arguments.
1657
Georg Brandlccadf842006-03-31 18:54:53 +00001658- Patch #1460496: round() now accepts keyword arguments.
1659
Anthony Baxter262c00a2006-03-30 10:53:17 +00001660- Fixed bug #1459029 - unicode reprs were double-escaped.
1661
Hye-Shik Changd478f342006-03-23 12:32:36 +00001662- Patch #1396919: The system scope threads are reenabled on FreeBSD
1663 5.4 and later versions.
1664
Neal Norwitze98ccf62006-03-23 05:39:47 +00001665- Bug #1115379: Compiling a Unicode string with an encoding declaration
1666 now gives a SyntaxError.
1667
Georg Brandlabd1ff82006-03-18 07:59:59 +00001668- Previously, Python code had no easy way to access the contents of a
1669 cell object. Now, a ``cell_contents`` attribute has been added
1670 (closes patch #1170323).
1671
Tim Peterscf79aac2006-03-16 01:14:46 +00001672- Patch #1123430: Python's small-object allocator now returns an arena to
1673 the system ``free()`` when all memory within an arena becomes unused
1674 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1675 freed. Some applications will see a drop in virtual memory size now,
1676 especially long-running applications that, from time to time, temporarily
1677 use a large number of small objects. Note that when Python returns an
1678 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001679 platform C library will in turn return that memory to the operating system.
1680 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001681 appears to be effective at least on Microsoft C and gcc-based systems.
1682 Thanks to Evan Jones for hard work and patience.
1683
Georg Brandl533ff6f2006-03-08 18:09:27 +00001684- Patch #1434038: property() now uses the getter's docstring if there is
1685 no "doc" argument given. This makes it possible to legitimately use
1686 property() as a decorator to produce a read-only property.
1687
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001688- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1689 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1690 of requiring an int or long in slicing and a few other contexts, enabling
1691 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1692
Neal Norwitz995acdf2006-03-07 05:01:00 +00001693- Fixed various bugs reported by Coverity's Prevent tool.
1694
Brett Cannonbf364092006-03-01 04:25:17 +00001695- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1696 new exception base class, BaseException, which has a new message attribute.
1697 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1698 Raising a string exception now raises a DeprecationWarning.
1699
Thomas Woutersfb609f42006-02-28 16:37:25 +00001700- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1701 explicitly relative, using 'from .module import name' to mean 'from the same
1702 package as this module is in. Imports without dots still default to the
1703 old relative-then-absolute, unless 'from __future__ import
1704 absolute_import' is used.
1705
Brett Cannona7446e32006-02-27 23:39:10 +00001706- Properly check if 'warnings' raises an exception (usually when a filter set
1707 to "error" is triggered) when raising a warning for raising string
1708 exceptions.
1709
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001710- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001711 The name was removed from Include/code.h.
1712
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001713- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001714
Guido van Rossum1968ad32006-02-25 22:38:04 +00001715- Patch 1433928:
1716 - The copy module now "copies" function objects (as atomic objects).
1717 - dict.__getitem__ now looks for a __missing__ hook before raising
1718 KeyError.
1719
Tim Peters84ef21c2006-02-28 20:39:06 +00001720- PEP 343: with statement implemented. Needs ``from __future__ import
1721 with_statement``. Use of 'with' as a variable will generate a warning.
1722 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001723 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001724 The following objects have __context__ methods:
1725 - The built-in file type.
1726 - The thread.LockType type.
1727 - The following types defined by the threading module:
1728 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1729 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001730
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001731- Fix the encodings package codec search function to only search
1732 inside its own package. Fixes problem reported in patch #1433198.
1733
1734 Note: Codec packages should implement and register their own
1735 codec search function. PEP 100 has the details.
1736
Tim Peters9ea89d22006-06-04 03:26:02 +00001737- PEP 353: Using ``Py_ssize_t`` as the index type.
1738
1739- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1740 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1741 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1742 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1743 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001744
Neal Norwitzfc76d632006-01-10 06:03:13 +00001745- Patch #1400181, fix unicode string formatting to not use the locale.
1746 This is how string objects work. u'%f' could use , instead of .
1747 for the decimal point. Now both strings and unicode always use periods.
1748
Neal Norwitz671b9e32006-01-09 07:07:12 +00001749- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1750 configure would break checking curses.h.
1751
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001752- Bug #959576: The pwd module is now builtin. This allows Python to be
1753 built on UNIX platforms without $HOME set.
1754
Neal Norwitzc10978f2005-12-19 06:07:16 +00001755- Bug #1072182, fix some potential problems if characters are signed.
1756
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001757- Bug #889500, fix line number on SyntaxWarning for global declarations.
1758
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001759- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1760
Neal Norwitze7214a12005-12-18 05:03:17 +00001761- Support for converting hex strings to floats no longer works.
1762 This was not portable. float('0x3') now raises a ValueError.
1763
Barry Warsaw2a38a862005-12-18 01:27:35 +00001764- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001765 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001766 is now displayed in interactive prompt banner.
1767
Georg Brandlfa166682005-12-17 21:45:17 +00001768- Implementation of PEP 341 - Unification of try/except and try/finally.
1769 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001770 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001771
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001772- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1773 now encodes backslash correctly.
1774
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001775- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1776
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001777- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001778 and long longs.

Neal Norwitz67715f02005-11-09 06:59:35 +00001780- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001781 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001782 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001783
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001784- Replaced most Unicode charmap codecs with new ones using the
1785 new Unicode translate string feature in the builtin charmap
1786 codec; the codecs were created from the mapping tables available
1787 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1788 encodings now include a mapping for the Apple logo)
1789
Tim Peterse3547fd2005-12-16 23:13:57 +00001790- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001791
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001792- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001793
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001794- A new AST parser implementation was completed. The abstract
1795 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001796 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001797
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001798- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001799 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1800
Neal Norwitz708e51a2005-10-03 04:48:15 +00001801- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1802
Neal Norwitz11bd1192005-10-03 00:54:56 +00001803- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1804 Provide a warning when a directory is passed on the command line.
1805
Neal Norwitz40d37812005-10-02 01:48:49 +00001806- Fix segfault with invalid coding.
1807
1808- SF bug #772896: unknown encoding results in MemoryError.
1809
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001810- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001811 supported a __len__() method which evaluated to False when the iterator
1812 was empty.
1813
Guido van Rossum630db602005-09-20 18:49:54 +00001814- On 64-bit platforms, when __len__() returns a value that cannot be
1815 represented as a C int, raise OverflowError.
1816
Skip Montanarof8948ca2005-09-19 03:54:46 +00001817- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001818 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001819
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001820- SF bug #893549: parsing keyword arguments was broken with a few format
1821 codes.
1822
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001823- Changes donated by Elemental Security to make it work on AIX 5.3
1824 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1825 bug #105470: test_pwd fails on 64bit system (Opteron).
1826
Guido van Rossum539c6622005-09-14 17:49:54 +00001827- Changes donated by Elemental Security to make it work on HP-UX 11 on
1828 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1829
Georg Brandl4550b8d2005-08-26 06:43:52 +00001830- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001831 (fixes bug #1119418).
1832
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001833- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1834
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001835- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1836 exceptions that cause a function to exit.
1837
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001838- The implementation of set() and frozenset() was revised to use its
1839 own internal data structure. Memory consumption is reduced by 1/3
1840 and there are modest speed-ups as well. The API is unchanged.
1841
Tim Petersde7990b2005-07-17 23:45:23 +00001842- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1843
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001844- SF bug #1229429: PyObject_CallMethod failed to decrement some
1845 reference counts in some error exit cases.
1846
Tim Petersecc6e6a2005-07-10 22:30:55 +00001847- SF bug #1185883: Python's small-object memory allocator took over
1848 a block managed by the platform C library whenever a realloc specified
1849 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001850 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001851 portable way to copy data from the C-managed block into Python's
1852 small-object space without risking a memory fault. Python's small-object
1853 realloc now leaves such blocks under the control of the platform C
1854 realloc.
1855
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001856- SF bug #1232517: An overflow error was not detected properly when
1857 attempting to convert a large float to an int in os.utime().
1858
Raymond Hettinger3296e692005-06-29 23:29:56 +00001859- SF bug #1224347: hex longs now print with lowercase letters just
1860 like their int counterparts.
1861
Michael W. Hudson188d4362005-06-20 16:52:57 +00001862- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1863 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1864 interpreter states; back out that fix and do a better job (see
1865 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1866 for a longer write-up of the problem).
1867
Michael W. Hudsondf888462005-06-03 14:41:55 +00001868- SF patch #1180995: marshal now uses a binary format by default when
1869 serializing floats.
1870
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001871- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1872 the routines that promise to produce IEEE 754 binary representations
1873 of floats now simply copy bytes around.
1874
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001875- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1876 278.
1877
Brett Cannonc3647ac2005-04-26 03:45:26 +00001878- patch #1109424: int, long, float, complex, and unicode now check for the
1879 proper magic slot for type conversions when subclassed. Previously the
1880 magic slot was ignored during conversion. Semantics now match the way
1881 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001882 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001883 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001884 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001885
Barry Warsawc8d907c2005-04-19 23:43:40 +00001886- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1887 NULL, now raise an AttributeError when attempting to set or delete the
1888 attribute. Previously a TypeError was raised, but this was inconsistent
1889 with the equivalent pure-Python implementation.
1890
Michael W. Hudson774479c2005-04-18 08:46:17 +00001891- It is now safe to call PyGILState_Release() before
1892 PyEval_InitThreads() (note that if there is reason to believe there
1893 are multiple threads around you still must call PyEval_InitThreads()
1894 before using the Python API; this fix is for extension modules that
1895 have no way of knowing if Python is multi-threaded yet).
1896
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001897- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1898 disabled caused a crash.
1899
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001900- Bug #1165306: instancemethod_new allowed the creation of a method
1901 with im_class == im_self == NULL, which caused a crash when called.
1902
Tim Petersecc6e6a2005-07-10 22:30:55 +00001903- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001904 fixes the crash seen in bug #1165761
1905
Raymond Hettinger96229b12005-03-11 06:49:40 +00001906- Added two new builtins, any() and all().
1907
Brett Cannon409d8f22005-03-05 06:47:57 +00001908- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001909 (e.g., ``class C(): pass`` is no longer a syntax error).
1910 Patch #1176012 added support to the 'parser' module and 'compiler' package
1911 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001912
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001913- Patch #1115086: Support PY_LONGLONG in structmember.
1914
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001915- Bug #1155938: new style classes did not check that __init__() was
1916 returning None.
1917
Tim Petersecc6e6a2005-07-10 22:30:55 +00001918- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001919 ('\') with a specific error message.
1920
Martin v. Löwisff232d72005-03-03 09:24:38 +00001921- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1922
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001923- Bug #1124295: the __name__ attribute of file objects was
1924 inadvertently made inaccessible in restricted mode.
1925
Tim Petersecc6e6a2005-07-10 22:30:55 +00001926- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001927 an ferror() call.
1928
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001929- min() and max() now support key= arguments with the same meaning as in
1930 list.sort().
1931
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001932- The peephole optimizer now performs simple constant folding in expressions:
1933 (2+3) --> (5).
1934
Raymond Hettingera422c342005-01-11 03:03:27 +00001935- set and frozenset objects can now be marshalled. SF #1098985.
1936
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001937- Bug #1077106: Poor argument checking could cause memory corruption
1938 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001939
Jeremy Hyltonab630502005-02-04 18:44:06 +00001940- The parser did not complain about future statements in illegal
1941 positions. It once again reports a syntax error if a future
1942 statement occurs after anything other than a doc string.
1943
Neil Schemenauercf52c072005-08-12 17:34:58 +00001944- Change the %s format specifier for str objects so that it returns a
1945 unicode instance if the argument is not an instance of basestring and
1946 calling __str__ on the argument returns a unicode instance.
1947
Tim Petersf4e69282006-02-27 17:15:31 +00001948- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1949 current thread state when the auto-GIL-state machinery knows about
1950 it (since the thread state is being deleted, continuing to remember it
1951 can't help, but can hurt if another thread happens to get created with
1952 the same thread id).
1953
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001954Extension Modules
1955-----------------
1956

Neal Norwitz10be10c2006-03-16 06:50:13 +00001970 util, whatsound, whrandom, zmod
1971
1972- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1973
1974- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001975 is deprecated. The undocumented re.engine variable no longer exists.
1976
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001977- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1978 SS2 (single-shift 2) escape sequences correctly.
1979
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001980- The unicodedata module was updated to the 4.1 version of the Unicode
1981 database. The 3.2 version is still available as unicodedata.db_3_2_0
1982 for applications that require this specific version (such as IDNA).
1983
Neal Norwitzb62c4332006-03-04 18:35:47 +00001984- The timing module is no longer built by default. It was deprecated
1985 in PEP 4 in Python 2.0 or earlier.
1986
Guido van Rossum1968ad32006-02-25 22:38:04 +00001987- Patch 1433928: Added a new type, defaultdict, to the collections module.
1988 This uses the new __missing__ hook behavior added to dict (see above).
1989
Georg Brandldbd83392006-02-20 09:42:33 +00001990- Bug #854823: socketmodule now builds on Sun platforms even when
1991 INET_ADDRSTRLEN is not defined.
1992
Georg Brandlf4f44152006-02-18 22:29:33 +00001993- Patch #1393157: os.startfile() now has an optional argument to specify
1994 a "command verb" to invoke on the file.
1995
Neal Norwitz082b2df2006-02-07 07:04:46 +00001996- Bug #876637, prevent stack corruption when socket descriptor
1997 is larger than FD_SETSIZE.
1998
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00001999- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
2000 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
2001 mmap.mmap(0, size) should not be used on Windows for anonymous memory.

Martin v. Löwis57a34e82006-02-04 19:12:37 +00002003- Patch #1422385: The nis module now supports access to domains other
2004 than the system default domain.
2005
Martin v. Löwis14694662006-02-03 12:54:16 +00002006- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2007 are reported, the limit on path name lengths is removed, and stat reports
2008 WindowsError now (instead of OSError).
2009
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002010- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002144- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2145 been renamed to have only a single underscore prefix. This was done to
2146 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002147
Nick Coghlan43832302006-04-23 17:04:07 +00002148- PEP 338: new module runpy defines a run_module function to support
2149 executing modules which provide access to source code or a code object
2150 via the PEP 302 import mechanisms.
2151
Anthony Baxter93f5b932006-04-03 08:05:07 +00002152- The email module's parsedate_tz function now sets the daylight savings

2160 in attribute values.
2161
Anthony Baxterc51ee692006-04-01 00:57:31 +00002162- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002163 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002164 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002165 module will not be built.
2166
Tim Petersc17976e2006-04-01 00:26:53 +00002167- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2168 aren't officially supported here, and trying to use them will probably
2169 raise an exception some day. But dicts have been allowed, and "mostly
2170 worked", so support for them won't go away without warning.
2171
Georg Brandl338ef7d2006-03-31 18:42:16 +00002172- Bug #1445068: getpass.getpass() can now be given an explicit stream
2173 argument to specify where to write the prompt.
2174

2182
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002183- Queue.Queue objects now support .task_done() and .join() methods
2184 to make it easier to monitor when daemon threads have completed
2185 processing all enqueued tasks. Patch #1455676.
2186

2190
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002191- email 4.0 package now integrated. This is largely the same as the email 3.0
2192 package that was included in Python 2.3, except that PEP 8 module names are
2193 now used (e.g. mail.message instead of email.Message). The MIME classes
2194 have been moved to a subpackage (e.g. email.mime.text instead of
2195 email.MIMEText). The old names are still supported for now. Several
2196 deprecated Message methods have been removed and lots of bugs have been
2197 fixed. More details can be found in the email package documentation.
2198
Walter Dörwald40108c92006-03-27 08:15:44 +00002199- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2200 (a subclass of tuple) that provides incremental decoders and encoders
2201 (a way to use stateful codecs without the stream API). Python functions
2202 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2203 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2204 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002205
Walter Dörwald067db482006-03-15 22:17:27 +00002206- Patch #1359365: Calling next() on a closed StringIO.String object raises
2207 a ValueError instead of a StopIteration now (like file and cString.String do).
2208 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2209 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002210
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002211- A regrtest option -w was added to re-run failed tests in verbose mode.

2221
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002222- PEP 343: new module contextlib.py defines decorator @contextmanager
2223 and helpful context managers nested() and closing().
2224

Martin v. Löwis3e865952006-01-24 15:51:21 +00002259 specifications, raises IOErrors when proxies for unsupported protocols
2260 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00002283 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2284 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2285 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2286 Ronald L. Rivest offered this advice for Python:
2287
2288 "The consensus of researchers in this area (at least as
2289 expressed at the NIST Hash Function Workshop 10/31/05),
2290 is that SHA-256 is a good choice for the time being, but
2291 that research should continue, and other alternatives may
2292 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002293
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002294- Added a subset of Fredrik Lundh's ElementTree package. Available

2347 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002348 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002349

2371 to W3C name (404 -> 'Not Found'). RFE #1216944.
2372
Georg Brandl9e43acf2005-07-04 17:16:07 +00002373- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2374 as this can cause problems with apps closing all file descriptors.

2387 Bug #1224621.
2388
Raymond Hettinger68c04532005-06-10 11:05:19 +00002389- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002390 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002391 the generate_tokens() function now accepts a callable argument that
2392 terminates by raising StopIteration.
2393
Georg Brandl9166e1a2005-06-04 09:20:03 +00002394- Bug #1196315: fix weakref.WeakValueDictionary constructor.

2402 class at all.
2403
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002404- distutils.commands.upload was added to support uploading distribution
2405 files to PyPI.
2406
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002407- distutils.commands.register now encodes the data as UTF-8 before posting
2408 them to PyPI.
2409
Raymond Hettinger267b8682005-03-27 10:47:39 +00002410- decimal operator and comparison methods now return NotImplemented
2411 instead of raising a TypeError when interacting with other types. This
2412 allows other classes to implement __radd__ style methods and have them
2413 work as expected.
2414
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002415- Bug #1163325: Decimal infinities failed to hash. Attempting to
2416 hash a NaN raised an InvalidOperation instead of a TypeError.
2417
Tim Petersecc6e6a2005-07-10 22:30:55 +00002418- Patch #918101: Add tarfile open mode r|* for auto-detection of the

2452
Guido van Rossumd0641422005-02-03 15:01:24 +00002453- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2454 disables recursive traversal through instance attributes, which can
2455 be exploited in various ways.
2456
Tim Peterse3547fd2005-12-16 23:13:57 +00002457- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002458 flags on the HTTP listening socket.
2459
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002460- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2461 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2462
Fred Drakefbdeaad2006-07-29 16:56:15 +00002463- Patches #893642, #1039083: add allow_none, encoding arguments to
2464 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002465
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002466- Bug #1110478: Revert os.environ.update to do putenv again.
2467
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002468- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2469
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002470- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2471
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002472- Enhancements to the csv module:
2473
2474 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002475 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002476 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002477 + Dialect parameter parsing has been re-implemented to improve error
2478 reporting.
2479 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2480 dictates.
2481 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002482 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002483 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002484 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2485 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002486 + reader now allows \r characters to be quoted (previously it only allowed
2487 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002488 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002489 + Dialect classes passed to the module are no longer instantiated by
2490 the module before being parsed (the former validation scheme required
2491 this, but the mechanism was unreliable).
2492 + The dialect registry now contains instances of the internal
2493 C-coded dialect type, rather than references to python objects.
2494 + the internal c-coded dialect type is now immutable.
2495 + register_dialect now accepts the same keyword dialect specifications
2496 as the reader and writer, allowing the user to register dialects
2497 without first creating a dialect class.
2498 + a configurable limit to the size of parsed fields has been added -
2499 previously, an unmatched quote character could result in the entire
2500 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002501 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002502 the parser field size limit (returning the former limit). The initial
2503 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002504 + A line_num attribute has been added to the reader object, which tracks
2505 the number of lines read from the source iterator. This is not
2506 the same as the number of records returned, as records can span
2507 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002508 + reader and writer objects were not being registered with the cyclic-GC.
2509 This has been fixed.
2510
Brett Cannone6539c42005-01-08 02:43:53 +00002511- _DummyThread objects in the threading module now delete self.__block that is
2512 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2513 lock primitives tend to be limited in number and thus should not be wasted on
2514 a _DummyThread object. Fixes bug #1089632.
2515
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002516- The imghdr module now detects Exif files.
2517
Raymond Hettinger6065d322004-12-20 23:51:53 +00002518- StringIO.truncate() now correctly adjusts the size attribute.
2519 (Bug #951915).
2520
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002521- locale.py now uses an updated locale alias table (built using
2522 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2523 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002524 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002525
Raymond Hettinger3557f422004-12-07 12:02:02 +00002526- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2527
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002528- the pickle module no longer accepts the deprecated None option in the
2529 args tuple returned by __reduce__().
2530
Brett Cannon84667c02004-12-07 03:25:18 +00002531- optparse now optionally imports gettext. This allows its use in setup.py.
2532
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002533- the pickle module no longer uses the deprecated bin parameter.
2534
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002535- the shelve module no longer uses the deprecated binary parameter.
2536
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002537- the pstats module no longer uses the deprecated ignore() method.
2538
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002539- the filecmp module no longer uses the deprecated use_statcache argument.
2540
Raymond Hettinger664347b2004-12-04 21:21:53 +00002541- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2542 extended or overridden by subclasses. Formerly, the subclassed method would
2543 be ignored by the rest of the module. (Bug #1078905).
2544
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002545- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002546 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002547
Walter Dörwald36733692004-12-22 12:50:50 +00002548- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2549 once when a size argument is given. This prevents a buffer overflow in the
2550 tokenizer with very long source lines.
2551
Barry Warsaw538561e2006-01-01 21:48:54 +00002552- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2553 immediately after creating the object, without any intervening
2554 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002555
Skip Montanaro05885812005-01-16 20:48:27 +00002556- The reconvert.quote function can now emit triple-quoted strings. The
2557 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002558
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002559- ``UserString.MutableString`` now supports negative indices in
2560 ``__setitem__`` and ``__delitem__``
2561
Greg Ward40407942005-03-05 02:53:17 +00002562- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2563 correctly.
2564
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002565- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2566 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2567 character even if the user has passed a size parameter to get a proper
2568 line ending. Remove the special handling of a "\r\n" that has been split
2569 between two lines.
2570
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002571- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2572 about illegal code points. The codec now supports PEP 293 style error
2573 handlers.
2574
Walter Dörwald78a78b02005-09-01 12:04:29 +00002575- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002576 from the input stream, so that the output is a byte string in the correct
2577 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002578
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002579- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2580 considering it exactly like a '*'.
2581
Walter Dörwald007f8df2005-10-09 19:42:27 +00002582- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2583 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002584
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002585- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2586
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002587- Patch #1413711: Certain patterns of differences were making difflib
2588 touch the recursion limit.
2589
Walter Dörwald58917a62006-03-31 15:26:22 +00002590- Bug #947906: An object oriented interface has been added to the calendar
2591 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002592 called as a script (e.g. via ``python -mcalendar``). Localized month and
2593 weekday names can be ouput (even if an exotic encoding is used) using
2594 special classes that use unicode.

2597-----
2598
Neal Norwitz602d3392006-03-31 08:21:40 +00002599- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2600 by using -mieee gcc option.
2601

2603
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002604- Build support for Win64-AMD64 was added.
2605
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002606- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2607
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002608- Patch #881820: look for openpty and forkpty also in libbsd.
2609
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002610- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2611 The zlib module is now builtin on Windows.
2612
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002613- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2614
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002615- Bug #1189330: configure did not correctly determine the necessary
2616 value of LINKCC if python was built with GCC 4.0.
2617
Trent Mick8321b422005-07-26 02:29:21 +00002618- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2619 vulnerability in zlib 1.2.1 and 1.2.2.
2620
Brett Cannon08cd5982005-04-24 22:26:38 +00002621- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2622 flags that change binary compatibility. Changes were also made to
2623 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002624 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002625
Bob Ippolitoed233462005-03-29 13:47:59 +00002626- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2627 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2628 no longer exists). This configure patch makes things right.
2629
Martin v. Löwise2713be2005-03-08 15:03:08 +00002630- Bug #1158607: Build with --disable-unicode again.
2631
Brett Cannon46d96232005-02-16 00:07:19 +00002632- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2633 defined. Discovered as a result of not being able to build on OS X.
2634
Brett Cannon516592f2004-12-07 00:42:59 +00002635- setup.py now uses the directories specified in LDFLAGS using the -L option
2636 and in CPPFLAGS using the -I option for adding library and include
2637 directories, respectively, for compiling extension modules against. This has
2638 led to the core being compiled using the values in CPPFLAGS. It also removes
2639 the need for the special-casing of both DarwinPorts and Fink for darwin since
2640 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2641 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2642 Fink, ``-I/opt/local/include`` for DarwinPorts).
2643
Brett Cannon43802422005-02-10 20:48:03 +00002644- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2645 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2646 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2647 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002649C API
2650-----
2651
Tim Petersc9d78aa2006-03-26 23:27:58 +00002652- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2653 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2654 is obtained via the ``PyObject_`` family, it must be released via the
2655 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2656 always been officially true, but when Python's small-object allocator was
2657 introduced, an attempt was made to cater to a few extension modules
2658 discovered at the time that obtained memory via ``PyObject_New`` but
2659 released it via ``PyMem_DEL``. It's years later, and if such code still
2660 exists it will fail now (probably with segfaults, but calling wrong
2661 low-level memory management functions can yield many symptoms).
2662
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002663- Added a C API for set and frozenset objects.
2664

2666
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002667- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2668 mapping argument now. This string is used as a mapping table. Byte values
2669 greater than the length of the string and 0xFFFE are treated as undefined
2670 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00002676- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002677
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002678- Patch #1276356: New resource "urlfetch" is implemented. This enables
2679 even impatient people to run tests that require remote files.
