450 generator expressions (x for x, in ... ) works again. Fixing this problem
451 required changing the .pyc magic number. This means that .pyc files
452 generated before 2.5c2 will be regenerated.

562
Neal Norwitz24b6f202006-09-05 04:43:56 +0000563- Fix infinite recursion when subclassing long and overriding __hash__.
564
565- Fix concatenation (+=) of long strings.
566
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000567- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000568 compared equal or unequal to a string and a UnicodeDecodeError
569 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000570
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000571 Instead, the equal (==) and unequal (!=) comparison operators will
572 now issue a UnicodeWarning and interpret the two objects as
573 unequal. The UnicodeWarning can be filtered as desired using
574 the warning framework, e.g. silenced completely, turned into an
575 exception, logged, etc.
576
577 Note that compare operators other than equal and unequal will still
578 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000579

587

590 were handled. This patch attempts to provide enough alternatives
591 to effectively use __index__.
592
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000593- Bug #1536021: __hash__ may now return long int; the final hash
594 value is obtained by invoking hash on the long int.
595

605 on each iteration. Fixing this problem required changing the .pyc
606 magic number. This means that .pyc files generated before 2.5c1
607 will be regenerated.
608
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000609- Bug #1333982: string/number constants were inappropriately stored
610 in the byte code and co_consts even if they were not used, ie
611 immediately popped off the stack.
612
Georg Brandle9462c72006-08-04 18:03:37 +0000613- Fixed a reference-counting problem in property().

617-------
618
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000619- Fix a bug in the ``compiler`` package that caused invalid code to be
620 generated for generator expressions.
621
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000622- The distutils version has been changed to 2.5.0. The change to
623 keep it programmatically in sync with the Python version running
624 the code (introduced in 2.5b3) has been reverted. It will continue
625 to be maintained manually as static string literal.
626
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000627- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000628 and this cannot be converted to the required C type, an exception is
629 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000630 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000631
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000632- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000633 an exception.
634
Tim Peterscbdd3502006-09-05 01:47:53 +0000635- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000636 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000637 workarounds for clocks with low resolution, to stop the code yielding
638 duplicate UUIDs.
639
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000640- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
641 before raising SystemExit, allowing IDLE to honor quit() and exit().
642
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000643- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
644
Georg Brandl7a1af772006-08-14 21:55:28 +0000645- Patch #1536071: trace.py should now find the full module name of a
646 file correctly even on Windows.
647
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000648- logging's atexit hook now runs even if the rest of the module has
649 already been cleaned up.
650
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000651- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000652
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000653- Bug #1531405, format_exception no longer raises an exception if
654 str(exception) raised an exception.
655
Neil Schemenauer06ded092006-08-04 16:20:30 +0000656- Fix a bug in the ``compiler`` package that caused invalid code to be
657 generated for nested functions.

668 raises the correct exceptions.
669
Thomas Heller1ce433e2006-08-14 16:20:04 +0000670- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
671 '-no-stack-protector' compiler flag for OpenBSD has been removed.
672
Thomas Heller86720042006-08-14 11:17:48 +0000673- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
674 uses the _as_parameter_ attribute when objects are passed to foreign
675 function calls. The ctypes version number was changed to 1.0.1.
676
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000677- Bug #1530559, struct.pack raises TypeError where it used to convert.
678 Passing float arguments to struct.pack when integers are expected
679 now triggers a DeprecationWarning.

Martin v. Löwisa09fd6e2006-08-16 12:55:10 +0000705- Bug #1535502, build _hashlib on Windows, and use masm assembler
706 code in OpenSSL.
707
Thomas Hellerdb7b4432006-08-04 19:49:31 +0000708- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

714-----
715
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000716- New API for Unicode rich comparisons: PyUnicode_RichCompare()
717
Tim Peters4643c2f2006-08-10 22:45:34 +0000718- Bug #1069160. Internal correctness changes were made to
719 ``PyThreadState_SetAsyncExc()``. A test case was added, and
720 the documentation was changed to state that the return value
721 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +0000724What's New in Python 2.5 beta 3?
725================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000726
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000727*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000728
729Core and builtins
730-----------------
731
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000732- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000733 returned a long (see PEP 353).
734
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000735- Bug #1515471: string.replace() accepts character buffers again.
736
Neal Norwitz07aadb12006-07-30 06:55:48 +0000737- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
738 This provides the proper warning for struct.pack().
739 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
740
Neal Norwitz0d62a062006-07-30 06:53:31 +0000741- Patch #1531113: Fix augmented assignment with yield expressions.
742 Also fix a SystemError when trying to assign to yield expressions.
743
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000744- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
745 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
746 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
747 excessive filesystem operations during imports.
748
Tim Petersbc24eee2006-07-27 01:14:53 +0000749- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
750 operations on signed longs that are formally undefined by C.
751 Unfortunately, at least one compiler now cares about that, so complicated
752 the code to make that compiler happy again.
753
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000754- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
755
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000756- Patch #1232023: Stop including current directory in search
757 path on Windows.
758
Neal Norwitze1fdb322006-07-21 05:32:28 +0000759- Fix some potential crashes found with failmalloc.
760
Neal Norwitze7563102006-07-17 01:00:16 +0000761- Fix warnings reported by Klocwork's static analysis tool.
762
Neal Norwitz84be93b2006-07-16 01:50:38 +0000763- Bug #1512814, Fix incorrect lineno's when code within a function
764 had more than 255 blank lines.
765
Georg Brandl9dceedb2006-07-12 15:31:17 +0000766- Patch #1521179: Python now accepts the standard options ``--help`` and
767 ``--version`` as well as ``/?`` on Windows.
768
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000769- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000770 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000771 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000772
Tim Peters112aad32006-07-19 00:03:19 +0000773- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000774 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000775 new ``sys._current_frames()`` returns a dictionary with one entry,
776 mapping the faux "thread id" 0 to the current frame.
777
Ronald Oussoren3075e162006-07-25 20:28:55 +0000778- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000779
Ronald Oussoren3075e162006-07-25 20:28:55 +0000780
Neal Norwitza1f10902006-07-12 07:28:29 +0000781Library
782-------
783
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000784- Correction of patch #1455898: In the mbcs decoder, set final=False
785 for stream decoder, but final=True for the decode function.
786
Georg Brandl07fec3a2006-08-01 18:49:24 +0000787- os.urandom no longer masks unrelated exceptions like SystemExit or
788 KeyboardInterrupt.
789
Tim Peters4643c2f2006-08-10 22:45:34 +0000790- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000791 shutil.copytree on Windows
792
Georg Brandle34ac7c2006-07-30 11:07:23 +0000793- Bug #1002398: The documentation for os.path.sameopenfile now correctly
794 refers to file descriptors, not file objects.
795
Tim Peterscbdd3502006-09-05 01:47:53 +0000796- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000797 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000798 #1513611, and probably others.
799
Georg Brandledd9b0d2006-07-29 09:33:26 +0000800- Bug #1441397: The compiler module now recognizes module and function
801 docstrings correctly as it did in Python 2.4.
802
Tim Peters6f681472006-07-27 23:44:37 +0000803- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
804 lost that tests are sorted by name before being run. This rarely
805 matters for well-written tests, but can create baffling symptoms if
806 side effects from one test to the next affect outcomes. ``DocTestFinder``
807 has been changed to sort the list of tests it returns.
808
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000809- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000810 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000811
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000812- Bug #978833: Really close underlying socket in _socketobject.close.
813
Georg Brandldb232dc2006-08-20 13:15:43 +0000814- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
815 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000816
Georg Brandlcf0c1722006-07-26 07:23:32 +0000817- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
818 to recursive calls and call it with the failing package name.
819
Martin v. Löwis0b483032006-07-25 09:53:12 +0000820- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
821
Georg Brandlc13c34c2006-07-24 14:09:56 +0000822- Patch #1515343: Fix printing of deprecated string exceptions with a
823 value in the traceback module.
824
Greg Ward48fae7a2006-07-23 16:05:51 +0000825- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
826
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000827- Patch #1524429: Use repr() instead of backticks in Tkinter again.
828
Brett Cannoncaebe222006-07-18 04:41:36 +0000829- Bug #1520914: Change time.strftime() to accept a zero for any position in its
830 argument tuple. For arguments where zero is illegal, the value is forced to
831 the minimum value that is correct. This is to support an undocumented but
832 common way people used to fill in inconsequential information in the time
833 tuple pre-2.4.
834
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000835- Patch #1220874: Update the binhex module for Mach-O.
836
Barry Warsawb110bad2006-07-21 14:51:07 +0000837- The email package has improved RFC 2231 support, specifically for
838 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
839 (name*0=<blah>) parameter continuations. This may change the types of
840 values returned from email.message.Message.get_param() and friends.
841 Specifically in some cases where non-encoded continuations were used,
842 get_param() used to return a 3-tuple of (None, None, string) whereas now it
843 will just return the string (since non-encoded continuations don't have
844 charset and language parts).
845
846 Also, whereas % values were decoded in all parameter continuations, they are
847 now only decoded in encoded parameter parts.
848
Ronald Oussoren3075e162006-07-25 20:28:55 +0000849- Bug #1517990: IDLE keybindings on MacOS X now work correctly
850
851- Bug #1517996: IDLE now longer shows the default Tk menu when a
852 path browser, class browser or debugger is the frontmost window on MacOS X
853
Barry Warsaw00decd72006-07-27 23:43:15 +0000854- Patch #1520294: Support for getset and member descriptors in types.py,
855 inspect.py, and pydoc.py. Specifically, this allows for querying the type
856 of an object against these built-in types and more importantly, for getting
857 their docstrings printed in the interactive interpreter's help() function.

861-----------------
862
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000863- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
864 a socket operation on a socket with a timeout, the exception will be
865 caught correctly. Previously, the exception was not caught.
866
Thomas Heller1393d6a2006-07-28 21:43:20 +0000867- Patch #1529514: The _ctypes extension is now compiled on more
868 openbsd target platforms.
869
Tim Peters9cab5932006-07-28 00:30:00 +0000870- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
871 a memory leak, affecting pickles and deep copies.
872
Tim Petersbc24eee2006-07-27 01:14:53 +0000873- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000874 Paul Eggert.
875
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000876- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
877
Thomas Hellerce049a02006-07-14 17:51:14 +0000878- Patch #1521817: Index range checking on ctypes arrays containing
879 exactly one element enabled again. This allows iterating over these
880 arrays, without the need to check the array size before.
881
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000882- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000883 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000884 /dev/null in certain cases; this is now fixed.
885
Thomas Heller47d7a062006-07-12 08:43:47 +0000886- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
887 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000888
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000889- Because of a misspelled preprocessor symbol, ctypes was always
890 compiled without thread support; this is now fixed.

Gregory P. Smith641cddf2006-07-28 01:35:25 +0000892- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
893 methods now allow their database parameter to be None as the
894 sleepycat API allows.
895
Matt Flemingec926502006-07-28 11:27:27 +0000896- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different

Brett Cannonf23ad3d2006-07-25 17:32:20 +0000899Tests
900-----
901
902- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
903 how long the test file should take to play. Now accepts taking 2.93 secs
904 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
905
Georg Brandl4793aa32006-07-28 18:31:39 +0000906- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
907 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
908 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +0000915Mac
916---
917
918- PythonLauncher now works correctly when the path to the script contains
919 characters that are treated specially by the shell (such as quotes).
920
921- Bug #1527397: PythonLauncher now launches scripts with the working directory
922 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000923 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000924 expect.

932Core and builtins
933-----------------
934
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000935- Bug #1441486: The literal representation of -(sys.maxint - 1)
936 again evaluates to a int object, not a long.
937
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000938- Bug #1501934: The scope of global variables that are locally assigned
939 using augmented assignment is now correctly determined.
940
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000941- Bug #927248: Recursive method-wrapper objects can now safely
942 be released.
943
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000944- Bug #1417699: Reject locale-specific decimal point in float()
945 and atof().
946
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000947- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
948 omit a default "error" argument for NULL pointer. This allows
949 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000950
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000951- Bug #1519018: 'as' is now validated properly in import statements.
952
Neal Norwitz28746ab2006-07-09 22:14:42 +0000953- On 64 bit systems, int literals that use less than 64 bits are
954 now ints rather than longs.
955
Neal Norwitzed657552006-07-10 00:04:44 +0000956- Bug #1512814, Fix incorrect lineno's when code at module scope
957 started after line 256.
958
Tim Peters32a83612006-07-10 21:08:24 +0000959- New function ``sys._current_frames()`` returns a dict mapping thread
960 id to topmost thread stack frame. This is for expert use, and is
961 especially useful for debugging application deadlocks. The functionality
962 was previously available in Fazal Majid's ``threadframe`` extension
963 module, but it wasn't possible to do this in a wholly threadsafe way from
964 an extension.
965

Martin v. Löwis77621582006-07-30 13:27:31 +0000969- Bug #1257728: Mention Cygwin in distutils error message about a missing
970 VS 2003.
971

973
Tim Peters32a83612006-07-10 21:08:24 +0000974- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000975 environment variable to be set in order to the SDK environment
976 for finding the compiler, include files, etc.
977

Nick Coghlan2d792252006-07-06 13:47:18 +0000980- warnings.py now ignores ImportWarning by default
981
Thomas Woutersadd19112006-07-05 11:03:49 +0000982- string.Template() now correctly handles tuple-values. Previously,
983 multi-value tuples would raise an exception and single-value tuples would
984 be treated as the value they contain, instead.
985
Martin v. Löwisede77f52006-07-03 13:01:35 +0000986- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
987 even if some data are received.
988
Martin v. Löwis45482392006-07-03 12:28:58 +0000989- Bug #1267547: Put proper recursive setup.py call into the
990 spec file generated by bdist_rpm.

993 degrees and radians.
994
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000995- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000996 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000997
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000998- Bug #1514703: Only setup canvas window in turtle when the canvas
999 is created.
1000
Martin v. Löwis7596e832006-07-01 15:33:37 +00001001- Bug #1513223: .close() of a _socketobj now releases the underlying
1002 socket again, which then gets closed as it becomes unreferenced.
1003

1005 attribute values.
1006
1007- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1008 sgmllib ('[' and ']' were not accepted).
1009
Georg Brandl1be63af2006-06-28 20:23:25 +00001010- Fix a bug in the turtle module's end_fill function.
1011
Brett Cannon53ab5b72006-06-22 16:49:14 +00001012- Bug #1510580: The 'warnings' module improperly required that a Warning
1013 category be either a types.ClassType and a subclass of Warning. The proper
1014 check is just that it is a subclass with Warning as the documentation states.
1015
Georg Brandlad29e632006-06-21 17:45:17 +00001016- The compiler module now correctly compiles the new try-except-finally
1017 statement (bug #1509132).
1018
Neal Norwitz60373cd2006-06-22 06:30:50 +00001019- The wsgiref package is now installed properly on Unix.
1020
Vinay Sajip28e57612006-07-01 10:45:20 +00001021- A bug was fixed in logging.config.fileConfig() which caused a crash on
1022 shutdown when fileConfig() was called multiple times.
1023
Gerhard Häring762fbd32006-07-02 17:48:30 +00001024- The sqlite3 module did cut off data from the SQLite database at the first
1025 null character before sending it to a custom converter. This has been fixed
1026 now.
1027
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001028Extension Modules
1029-----------------
1030
Tim Peters112aad32006-07-19 00:03:19 +00001031- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1032 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1033 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001034
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001035- Assigning None to pointer type fields in ctypes structures possible
1036 overwrote the wrong fields, this is fixed now.
1037
1038- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1039 on non-Windows platforms.
1040
1041- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1042 integer or long, without range checking.
1043
1044- Patch #1517790: It is now possible to use custom objects in the ctypes
1045 foreign function argtypes sequence as long as they provide a from_param
1046 method, no longer is it required that the object is a ctypes type.
1047
1048- The '_ctypes' extension module now works when Python is configured
1049 with the --without-threads option.
1050
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001051- Bug #1513646: os.access on Windows now correctly determines write
1052 access, again.
1053
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001054- Bug #1512695: cPickle.loads could crash if it was interrupted with
1055 a KeyboardInterrupt.
1056
Neal Norwitza12aa882006-07-06 06:45:08 +00001057- Bug #1296433: parsing XML with a non-default encoding and
1058 a CharacterDataHandler could crash the interpreter in pyexpat.
1059
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001060- Patch #1516912: improve Modules support for OpenVMS.
1061
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001062Build
1063-----
1064
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001065- Automate Windows build process for the Win64 SSL module.
1066
Tim Peters32a83612006-07-10 21:08:24 +00001067- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001068 Previously, the slight difference could cause compilation errors of the
1069 'zlib' module on systems with more than one version of zlib.
1070
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001071- The MSI compileall step was fixed to also support a TARGETDIR
1072 with spaces in it.
1073
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001074- Bug #1517388: sqlite3.dll is now installed on Windows independent
1075 of Tcl/Tk.
1076
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001077- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001078 trying to be installed even though it's empty.

Neal Norwitzb15ac312006-06-29 04:10:08 +00001080Tests
1081-----
1082
1083- Call os.waitpid() at the end of tests that spawn child processes in order
1084 to minimize resources (zombies).
1085
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001086Documentation
1087-------------
1088
Nick Coghlan2d792252006-07-06 13:47:18 +00001089- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1090 documentation for the warnings module.
1091
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001092- Patch #1509163: MS Toolkit Compiler no longer available.
1093
Neal Norwitz56640df2006-07-10 02:36:41 +00001094- Patch #1504046: Add documentation for xml.etree.

1103-----------------
1104
Georg Brandla56b9152006-06-19 06:35:54 +00001105- Patch #1507676: Error messages returned by invalid abstract object operations
1106 (such as iterating over an integer) have been improved and now include the
1107 type of the offending object to help with debugging.
1108
Brett Cannonea3912b2006-06-13 21:46:41 +00001109- Bug #992017: A classic class that defined a __coerce__() method that returned
1110 its arguments swapped would infinitely recurse and segfault the interpreter.
1111
Neal Norwitz909eb122006-06-12 02:13:21 +00001112- Fix the socket tests so they can be run concurrently.
1113
Neal Norwitzb9845e72006-06-12 02:11:18 +00001114- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001115 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001116
Brett Cannon22565aa2006-06-09 22:31:23 +00001117- Bug #532646: object.__call__() will continue looking for the __call__
1118 attribute on objects until one without one is found. This leads to recursion
1119 when you take a class and set its __call__ attribute to an instance of the
1120 class. Originally fixed for classic classes, but this fix is for new-style.
1121 Removes the infinite_rec_3 crasher.
1122
Georg Brandl24250812006-06-09 18:45:48 +00001123- The string and unicode methods startswith() and endswith() now accept
1124 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1125
Brett Cannonde3b0522006-06-08 17:00:45 +00001126- Buffer objects, at the C level, never used the char buffer
1127 implementation even when the char buffer for the wrapped object was
1128 explicitly requested (originally returned the read or write buffer).
1129 Now a TypeError is raised if the char buffer is not present but is
1130 requested.
1131
Georg Brandlddbaa662006-06-04 21:56:52 +00001132- Patch #1346214: Statements like "if 0: suite" are now again optimized
1133 away like they were in Python 2.4.
1134
Georg Brandlb7c8f542006-05-27 12:30:25 +00001135- Builtin exceptions are now full-blown new-style classes instead of
1136 instances pretending to be classes, which speeds up exception handling
1137 by about 80% in comparison to 2.5a2.
1138
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001139- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1140 Unicode 4.1.
1141
Georg Brandlf4ef1162006-05-26 18:03:31 +00001142- Patch #921466: sys.path_importer_cache is now used to cache valid and
1143 invalid file paths for the built-in import machinery which leads to
1144 fewer open calls on startup.
1145
Tim Peters696cf432006-05-24 21:10:40 +00001146- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1147 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1148 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1149 the number of input digits (it was and remains linear-time for bases
1150 2, 4, 8, 16 and 32).
1151
Tim Petersb713ec22006-05-23 18:45:30 +00001152- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1153 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1154 an integer close to ``sys.maxint``. This was repaired by patch
1155 #1335972, which also gives a nice speedup.
1156
Richard Jonescebbefc2006-05-23 18:28:17 +00001157- Patch #1337051: reduced size of frame objects.
1158
1159- PyErr_NewException now accepts a tuple of base classes as its
1160 "base" parameter.
1161
Richard Jones7c88dcc2006-05-23 10:37:38 +00001162- Patch #876206: function call speedup by retaining allocated frame
1163 objects.
1164
Georg Brandl7b90e162006-05-18 07:01:27 +00001165- Bug #1462152: file() now checks more thoroughly for invalid mode
1166 strings and removes a possible "U" before passing the mode to the
1167 C library function.
1168
Neal Norwitz1004a532006-05-15 07:17:23 +00001169- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1170
Neal Norwitz373f0a72006-05-15 07:04:36 +00001171- Bug #1487966: Fix SystemError with conditional expression in assignment
1172
Martin v. Löwis879768d2006-05-11 13:28:43 +00001173- WindowsError now has two error code attributes: errno, which carries
1174 the error values from errno.h, and winerror, which carries the error
1175 values from winerror.h. Previous versions put the winerror.h values
1176 (from GetLastError()) into the errno attribute.
1177
Martin v. Löwis77736712006-05-04 05:51:03 +00001178- Patch #1475845: Raise IndentationError for unexpected indent.
1179
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001180- Patch #1479181: split open() and file() from being aliases for each other.
1181
Tim Peters44bd9862006-06-01 13:49:23 +00001182- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1183 methods were always silently ignored by dictionaries when comparing keys.
1184 They are now passed through (except when using the C API function
1185 ``PyDict_GetItem()``, whose semantics did not change).
1186
1187- Bug #1456209: In some obscure cases it was possible for a class with a
1188 custom ``__eq__()`` method to confuse dict internals when class instances
1189 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1190 No, you don't have any code that did this ;-)

1197- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1198
Brett Cannon6ee7d012006-06-08 16:23:04 +00001199- Change binascii.hexlify to accept a read-only buffer instead of only a char
1200 buffer and actually follow its documentation.
1201
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001202- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1203
Nick Coghlanc649ec52006-05-29 12:43:05 +00001204- Patch #1478788 (modified version): The functional extension module has
1205 been renamed to _functools and a functools Python wrapper module added.
1206 This provides a home for additional function related utilities that are
1207 not specifically about functional programming. See PEP 309.
1208
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001209- Patch #1493701: performance enhancements for struct module.
1210
Georg Brandl378d5922006-05-17 14:26:50 +00001211- Patch #1490224: time.altzone is now set correctly on Cygwin.
1212
Georg Brandl8d3342b2006-05-16 07:38:27 +00001213- Patch #1435422: zlib's compress and decompress objects now have a
1214 copy() method.
1215
Andrew MacIntyre92913322006-06-13 15:04:24 +00001216- Patch #1454481: thread stack size is now tunable at runtime for thread
1217 enabled builds on Windows and systems with Posix threads support.
1218
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001219- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1220 (up to the system limit of 32K characters).
1221
1222- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1223 As a result, these functions now raise WindowsError instead of OSError.
1224
Tim Peters7a822da2006-05-25 21:50:17 +00001225- ``time.clock()`` on Win64 should use the high-performance Windows
1226 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1227 Windows platforms).
1228
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001229- Calling Tk_Init twice is refused if the first call failed as that
1230 may deadlock.
1231
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001232- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1233 accept it without potentially using an uninitialized pointer.
1234
1235- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1236 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1237 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001238
Gregory P. Smith372b5832006-06-05 18:48:21 +00001239- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001240 [pybsddb project SF patch number 1466734]
1241
Gregory P. Smith372b5832006-06-05 18:48:21 +00001242- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1243 parameter is supplied. [SF pybsddb bug #1477863]
1244
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001245- bsddb: the __len__ method of a DB object has been fixed to return correct
1246 results. It could previously incorrectly return 0 in some cases.
1247 Fixes SF bug 1493322 (pybsddb bug 1184012).
1248
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001249- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1250 aborts the db transaction safely when a modifier callback fails.
1251 Fixes SF python patch/bug #1408584.
1252
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001253- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001254 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001255 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1256 database calls that would previously deadlock. [SF python bug #775414]
1257
Vinay Sajip28e57612006-07-01 10:45:20 +00001258- Patch #1446489: add support for the ZIP64 extensions to zipfile.

1280 mime.types file for determining MIME types.
1281
Georg Brandl2605ca82006-06-14 06:08:31 +00001282- Bug #1339007: Shelf objects now don't raise an exception in their
1283 __del__ method when initialization failed.
1284
Martin v. Löwisd8251432006-06-14 05:21:04 +00001285- Patch #1455898: The MBCS codec now supports the incremental mode for
1286 double-byte encodings.
1287
Tim Peters43898b42006-06-14 04:09:25 +00001288- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1289 guarantee that adjacent triples in the return list always describe
1290 non-adjacent blocks. Previously, a pair of matching blocks could end
1291 up being described by multiple adjacent triples that formed a partition
1292 of the matching pair.
1293
Greg Ward0e0c9f42006-06-11 16:24:11 +00001294- Bug #1498146: fix optparse to handle Unicode strings in option help,
1295 description, and epilog.
1296
Greg Wardd1c797e2006-06-11 14:42:41 +00001297- Bug #1366250: minor optparse documentation error.

Greg Ward7f547402006-06-11 00:40:49 +00001299- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1300 clarify docs.
1301
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001302- The wsgiref package has been added to the standard library.
1303
Nick Coghlan676725d2006-06-08 13:54:49 +00001304- The functions update_wrapper() and wraps() have been added to the functools
1305 module. These make it easier to copy relevant metadata from the original
1306 function when writing wrapper functions.
1307
Tim Petersd6a9eef2006-06-05 01:48:21 +00001308- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1309 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001310
Martin v. Löwis3f767792006-06-04 19:36:28 +00001311- Patch #1359618: Speed up charmap encoder by using a trie structure
1312 for lookup.
1313
Tim Petersd609b1a2006-06-02 23:22:51 +00001314- The functions in the ``pprint`` module now sort dictionaries by key
1315 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1316 if and only if its display required more than one line, although that
1317 wasn't documented. The new behavior increases predictability; e.g.,
1318 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1319
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001320- Patch #1497027: try HTTP digest auth before basic auth in urllib2

1322
Georg Brandl2b330372006-05-28 20:23:12 +00001323- Patch #1496206: improve urllib2 handling of passwords with respect to
1324 default HTTP and HTTPS ports.
1325
George Yoshidaf3c65de2006-05-28 16:39:09 +00001326- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1327
Bob Ippolito7298f272006-05-23 18:43:47 +00001328- Patch #1281707: speed up gzip.readline.
1329
Georg Brandlb89316f2006-05-17 15:51:16 +00001330- Patch #1180296: Two new functions were added to the locale module:
1331 format_string() to get the effect of "format % items" but locale-aware,
1332 and currency() to format a monetary number with currency sign.
1333
Georg Brandle3a25832006-05-17 14:56:04 +00001334- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1335 and several features added, such as speed and geometry control.
1336
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001337- Patch #1488881: add support for external file objects in bz2 compressed
1338 tarfiles.
1339
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001340- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1341 stdout arguments, making it possible to redirect input and output
1342 for remote debugging.
1343
1344- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1345 a couple of issues, notably handling of long file names using the
1346 GNU LONGNAME extension.
1347
1348- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1349 new flag when ``name`` is already the name of an option flag.
1350
1351- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1352 package.
1353
1354- Patch #1472854: make the rlcompleter.Completer class usable on non-
1355 UNIX platforms.

1395Core and builtins
1396-----------------
1397
Thomas Heller1b046642006-04-18 18:51:06 +00001398- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1399 by converting these apis from macros into exported functions again:
1400
1401 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1402 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1403 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1404 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1405 PyRun_String Py_CompileString
1406
Martin v. Löwis45294a92006-04-18 06:24:08 +00001407- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1408
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001409- All uses of PyStructSequence_InitType have been changed to initialize
1410 the type objects only once, even if the interpreter is initialized
1411 multiple times.
1412
Neal Norwitz61546162006-04-14 05:20:28 +00001413- Bug #1454485, array.array('u') could crash the interpreter. This was
1414 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1415 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1416
1417- Py_UNICODE is unsigned. It was always documented as unsigned, but
1418 due to a bug had a signed value in previous versions.
1419
Tim Peters3a5e8b12006-04-11 01:44:07 +00001420- Patch #837242: ``id()`` of any Python object always gives a positive
1421 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1422 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001423 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001424 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001425
Tim Peters3a5e8b12006-04-11 01:44:07 +00001426 def __hash__(self):
1427 return id(self) # WRONG
1428
1429 because a hash result must be a (short) Python int but it was always
1430 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001431 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001432 was always usable as a hash value before this patch. That's no longer
1433 necessarily so.
1434
1435- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001436 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001437 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001438 #1454844)
1439
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001440- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1441 involving generators that have paused outside of any ``try`` or ``with``
1442 blocks. (In 2.5a1, a paused generator that was part of a reference
1443 cycle could not be garbage collected, regardless of whether it was
1444 paused in a ``try`` or ``with`` block.)

1456
1457- Bug #1117761: bsddb.*open() no longer raises an exception when using
1458 the cachesize parameter.
1459
1460- Bug #1149413: bsddb.*open() no longer raises an exception when using
1461 a temporary db (file=None) with the 'n' flag to truncate on open.
1462
1463- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1464 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001465
Armin Rigoa9017c32006-04-19 11:50:27 +00001466- Patch #1062014: AF_UNIX sockets under Linux have a special
1467 abstract namespace that is now fully supported.

1470-------
1471
Peter Astrand7d1d4362006-07-14 14:04:45 +00001472- Bug #1223937: subprocess.CalledProcessError reports the exit status
1473 of the process using the returncode attribute, instead of
1474 abusing errno.
1475
Tim Peters711bf302006-04-25 03:31:36 +00001476- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1477 a doctest to be skipped (the code is not run, and the expected output
1478 or exception is ignored).
1479
Nick Coghlanda2268f2006-04-24 04:37:15 +00001480- Fixed contextlib.nested to cope with exceptions being raised and
1481 caught inside exit handlers.
1482
Greg Wardab05edc2006-04-23 03:47:58 +00001483- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1484 hex, octal, or binary; add ``append_const`` action; keep going if
1485 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1486 added ``epilog`` for better help generation).
1487
Tim Peters21fbd572006-04-21 21:18:10 +00001488- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1489 called from a thread spawned as a side effect of importing a module.
1490
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001491- The pydoc module now supports documenting packages contained in
1492 .zip or .egg files.
1493
1494- The pkgutil module now has several new utility functions, such
1495 as ``walk_packages()`` to support working with packages that are either
1496 in the filesystem or zip files.
1497
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001498- The mailbox module can now modify and delete messages from
1499 mailboxes, in addition to simply reading them. Thanks to Gregory
1500 K. Johnson for writing the code, and to the 2005 Google Summer of

1528
Anthony Baxter51bcb682006-04-05 14:51:42 +00001529Build
1530-----
1531
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001532- The Makefile now has a reindent target, which runs reindent.py on
1533 the library.
1534
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001535- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001538
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001539- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1540 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001541 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001542 CXX from --with-cxx-main, see description in README.
1543
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001544- Patch #1429775: Link extension modules with the shared libpython.
1545
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001546- Fixed a libffi build problem on MIPS systems.
1547
Tim Peters8931ff12006-05-13 23:28:20 +00001548- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1549 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1550 and "%zu" for unsigned integers of type ``size_t``.
1551
Anthony Baxter51bcb682006-04-05 14:51:42 +00001552Tests
1553-----
1554
Nick Coghlanda2268f2006-04-24 04:37:15 +00001555- test_contextlib now checks contextlib.nested can cope with exceptions
1556 being raised and caught inside exit handlers.
1557
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001558- test_cmd_line now checks operation of the -m and -c command switches
1559
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001560- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1561 it separately and by hand. It also wasn't cleaning up its changes to
1562 the current Decimal context.
1563
Thomas Woutersabd08882006-04-26 15:53:30 +00001564- regrtest.py now has a -M option to run tests that test the new limits of
1565 containers, on 64-bit architectures. Running these tests is only sensible
1566 on 64-bit machines with more than two gigabytes of memory. The argument
1567 passed is the maximum amount of memory for the tests to use.
1568
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001569Tools

1576-------------
1577
Tim Petersb06d28c2006-05-12 01:57:59 +00001578- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1579
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001580- PEP 343: Added Context Types section to the library reference
1581 and attempted to bring other PEP 343 related documentation into
1582 line with the implementation and/or python-dev discussions.
1583
Tim Peters8dc73d22006-04-24 02:03:16 +00001584- Bug #1337990: clarified that ``doctest`` does not support examples
1585 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001588What's New in Python 2.5 alpha 1?
1589=================================
1590
Anthony Baxterebed3f62006-04-03 15:03:44 +00001591*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001592
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001593Core and builtins
1594-----------------
1595
Nick Coghlan43832302006-04-23 17:04:07 +00001596- PEP 338: -m command line switch now delegates to runpy.run_module
1597 allowing it to support modules in packages and zipfiles
1598
Martin v. Löwisc661b882006-04-20 04:54:23 +00001599- On Windows, .DLL is not an accepted file name extension for
1600 extension modules anymore; extensions are only found if they
1601 end in .PYD.
1602
Martin v. Löwisea62d252006-04-03 10:56:49 +00001603- Bug #1421664: sys.stderr.encoding is now set to the same value as
1604 sys.stdout.encoding.
1605
Neal Norwitz92e212f2006-04-03 04:48:37 +00001606- __import__ accepts keyword arguments.
1607
Georg Brandlccadf842006-03-31 18:54:53 +00001608- Patch #1460496: round() now accepts keyword arguments.
1609
Anthony Baxter262c00a2006-03-30 10:53:17 +00001610- Fixed bug #1459029 - unicode reprs were double-escaped.
1611
Hye-Shik Changd478f342006-03-23 12:32:36 +00001612- Patch #1396919: The system scope threads are reenabled on FreeBSD
1613 5.4 and later versions.
1614
Neal Norwitze98ccf62006-03-23 05:39:47 +00001615- Bug #1115379: Compiling a Unicode string with an encoding declaration
1616 now gives a SyntaxError.
1617
Georg Brandlabd1ff82006-03-18 07:59:59 +00001618- Previously, Python code had no easy way to access the contents of a
1619 cell object. Now, a ``cell_contents`` attribute has been added
1620 (closes patch #1170323).
1621
Tim Peterscf79aac2006-03-16 01:14:46 +00001622- Patch #1123430: Python's small-object allocator now returns an arena to
1623 the system ``free()`` when all memory within an arena becomes unused
1624 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1625 freed. Some applications will see a drop in virtual memory size now,
1626 especially long-running applications that, from time to time, temporarily
1627 use a large number of small objects. Note that when Python returns an
1628 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001629 platform C library will in turn return that memory to the operating system.
1630 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001631 appears to be effective at least on Microsoft C and gcc-based systems.
1632 Thanks to Evan Jones for hard work and patience.
1633
Georg Brandl533ff6f2006-03-08 18:09:27 +00001634- Patch #1434038: property() now uses the getter's docstring if there is
1635 no "doc" argument given. This makes it possible to legitimately use
1636 property() as a decorator to produce a read-only property.
1637
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001638- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1639 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1640 of requiring an int or long in slicing and a few other contexts, enabling
1641 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1642
Neal Norwitz995acdf2006-03-07 05:01:00 +00001643- Fixed various bugs reported by Coverity's Prevent tool.
1644
Brett Cannonbf364092006-03-01 04:25:17 +00001645- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1646 new exception base class, BaseException, which has a new message attribute.
1647 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1648 Raising a string exception now raises a DeprecationWarning.
1649
Thomas Woutersfb609f42006-02-28 16:37:25 +00001650- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1651 explicitly relative, using 'from .module import name' to mean 'from the same
1652 package as this module is in. Imports without dots still default to the
1653 old relative-then-absolute, unless 'from __future__ import
1654 absolute_import' is used.
1655
Brett Cannona7446e32006-02-27 23:39:10 +00001656- Properly check if 'warnings' raises an exception (usually when a filter set
1657 to "error" is triggered) when raising a warning for raising string
1658 exceptions.
1659
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001660- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001661 The name was removed from Include/code.h.
1662
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001663- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001664
Guido van Rossum1968ad32006-02-25 22:38:04 +00001665- Patch 1433928:
1666 - The copy module now "copies" function objects (as atomic objects).
1667 - dict.__getitem__ now looks for a __missing__ hook before raising
1668 KeyError.
1669
Tim Peters84ef21c2006-02-28 20:39:06 +00001670- PEP 343: with statement implemented. Needs ``from __future__ import
1671 with_statement``. Use of 'with' as a variable will generate a warning.
1672 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001673 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001674 The following objects have __context__ methods:
1675 - The built-in file type.
1676 - The thread.LockType type.
1677 - The following types defined by the threading module:
1678 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1679 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001680
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001681- Fix the encodings package codec search function to only search
1682 inside its own package. Fixes problem reported in patch #1433198.
1683
1684 Note: Codec packages should implement and register their own
1685 codec search function. PEP 100 has the details.
1686
Tim Peters9ea89d22006-06-04 03:26:02 +00001687- PEP 353: Using ``Py_ssize_t`` as the index type.
1688
1689- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1690 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1691 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1692 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1693 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001694
Neal Norwitzfc76d632006-01-10 06:03:13 +00001695- Patch #1400181, fix unicode string formatting to not use the locale.
1696 This is how string objects work. u'%f' could use , instead of .
1697 for the decimal point. Now both strings and unicode always use periods.
1698
Neal Norwitz671b9e32006-01-09 07:07:12 +00001699- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1700 configure would break checking curses.h.
1701
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001702- Bug #959576: The pwd module is now builtin. This allows Python to be
1703 built on UNIX platforms without $HOME set.
1704
Neal Norwitzc10978f2005-12-19 06:07:16 +00001705- Bug #1072182, fix some potential problems if characters are signed.
1706
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001707- Bug #889500, fix line number on SyntaxWarning for global declarations.
1708
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001709- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1710
Neal Norwitze7214a12005-12-18 05:03:17 +00001711- Support for converting hex strings to floats no longer works.
1712 This was not portable. float('0x3') now raises a ValueError.
1713
Barry Warsaw2a38a862005-12-18 01:27:35 +00001714- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001715 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001716 is now displayed in interactive prompt banner.
1717
Georg Brandlfa166682005-12-17 21:45:17 +00001718- Implementation of PEP 341 - Unification of try/except and try/finally.
1719 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001720 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001721
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001722- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1723 now encodes backslash correctly.
1724
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001725- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1726
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001727- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001728 and long longs.
1729
Neal Norwitz67715f02005-11-09 06:59:35 +00001730- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001731 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001732 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001733
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001734- Replaced most Unicode charmap codecs with new ones using the
1735 new Unicode translate string feature in the builtin charmap
1736 codec; the codecs were created from the mapping tables available
1737 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1738 encodings now include a mapping for the Apple logo)
1739
Tim Peterse3547fd2005-12-16 23:13:57 +00001740- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001741
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001742- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001743
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001744- A new AST parser implementation was completed. The abstract
1745 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001746 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001747
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001748- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001749 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1750
Neal Norwitz708e51a2005-10-03 04:48:15 +00001751- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1752
Neal Norwitz11bd1192005-10-03 00:54:56 +00001753- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1754 Provide a warning when a directory is passed on the command line.
1755
Neal Norwitz40d37812005-10-02 01:48:49 +00001756- Fix segfault with invalid coding.
1757
1758- SF bug #772896: unknown encoding results in MemoryError.
1759
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001760- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001761 supported a __len__() method which evaluated to False when the iterator
1762 was empty.
1763
Guido van Rossum630db602005-09-20 18:49:54 +00001764- On 64-bit platforms, when __len__() returns a value that cannot be
1765 represented as a C int, raise OverflowError.
1766
Skip Montanarof8948ca2005-09-19 03:54:46 +00001767- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001768 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001769
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001770- SF bug #893549: parsing keyword arguments was broken with a few format
1771 codes.
1772
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001773- Changes donated by Elemental Security to make it work on AIX 5.3
1774 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1775 bug #105470: test_pwd fails on 64bit system (Opteron).
1776
Guido van Rossum539c6622005-09-14 17:49:54 +00001777- Changes donated by Elemental Security to make it work on HP-UX 11 on
1778 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1779
Georg Brandl4550b8d2005-08-26 06:43:52 +00001780- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001781 (fixes bug #1119418).
1782
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001783- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1784
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001785- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1786 exceptions that cause a function to exit.
1787
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001788- The implementation of set() and frozenset() was revised to use its
1789 own internal data structure. Memory consumption is reduced by 1/3
1790 and there are modest speed-ups as well. The API is unchanged.
1791
Tim Petersde7990b2005-07-17 23:45:23 +00001792- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1793
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001794- SF bug #1229429: PyObject_CallMethod failed to decrement some
1795 reference counts in some error exit cases.
1796
Tim Petersecc6e6a2005-07-10 22:30:55 +00001797- SF bug #1185883: Python's small-object memory allocator took over
1798 a block managed by the platform C library whenever a realloc specified
1799 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001800 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001801 portable way to copy data from the C-managed block into Python's
1802 small-object space without risking a memory fault. Python's small-object
1803 realloc now leaves such blocks under the control of the platform C
1804 realloc.
1805
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001806- SF bug #1232517: An overflow error was not detected properly when
1807 attempting to convert a large float to an int in os.utime().
1808
Raymond Hettinger3296e692005-06-29 23:29:56 +00001809- SF bug #1224347: hex longs now print with lowercase letters just
1810 like their int counterparts.
1811
Michael W. Hudson188d4362005-06-20 16:52:57 +00001812- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1813 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1814 interpreter states; back out that fix and do a better job (see
1815 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1816 for a longer write-up of the problem).
1817
Michael W. Hudsondf888462005-06-03 14:41:55 +00001818- SF patch #1180995: marshal now uses a binary format by default when
1819 serializing floats.
1820
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001821- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1822 the routines that promise to produce IEEE 754 binary representations
1823 of floats now simply copy bytes around.
1824
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001825- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1826 278.
1827
Brett Cannonc3647ac2005-04-26 03:45:26 +00001828- patch #1109424: int, long, float, complex, and unicode now check for the
1829 proper magic slot for type conversions when subclassed. Previously the
1830 magic slot was ignored during conversion. Semantics now match the way
1831 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001832 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001833 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001834 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001835
Barry Warsawc8d907c2005-04-19 23:43:40 +00001836- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1837 NULL, now raise an AttributeError when attempting to set or delete the
1838 attribute. Previously a TypeError was raised, but this was inconsistent
1839 with the equivalent pure-Python implementation.
1840
Michael W. Hudson774479c2005-04-18 08:46:17 +00001841- It is now safe to call PyGILState_Release() before
1842 PyEval_InitThreads() (note that if there is reason to believe there
1843 are multiple threads around you still must call PyEval_InitThreads()
1844 before using the Python API; this fix is for extension modules that
1845 have no way of knowing if Python is multi-threaded yet).
1846
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001847- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1848 disabled caused a crash.
1849
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001850- Bug #1165306: instancemethod_new allowed the creation of a method
1851 with im_class == im_self == NULL, which caused a crash when called.
1852
Tim Petersecc6e6a2005-07-10 22:30:55 +00001853- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001854 fixes the crash seen in bug #1165761
1855
Raymond Hettinger96229b12005-03-11 06:49:40 +00001856- Added two new builtins, any() and all().
1857
Brett Cannon409d8f22005-03-05 06:47:57 +00001858- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001859 (e.g., ``class C(): pass`` is no longer a syntax error).
1860 Patch #1176012 added support to the 'parser' module and 'compiler' package
1861 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001862
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001863- Patch #1115086: Support PY_LONGLONG in structmember.
1864
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001865- Bug #1155938: new style classes did not check that __init__() was
1866 returning None.
1867
Tim Petersecc6e6a2005-07-10 22:30:55 +00001868- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001869 ('\') with a specific error message.
1870
Martin v. Löwisff232d72005-03-03 09:24:38 +00001871- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1872
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001873- Bug #1124295: the __name__ attribute of file objects was
1874 inadvertently made inaccessible in restricted mode.
1875
Tim Petersecc6e6a2005-07-10 22:30:55 +00001876- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001877 an ferror() call.
1878
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001879- min() and max() now support key= arguments with the same meaning as in
1880 list.sort().
1881
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001882- The peephole optimizer now performs simple constant folding in expressions:
1883 (2+3) --> (5).
1884
Raymond Hettingera422c342005-01-11 03:03:27 +00001885- set and frozenset objects can now be marshalled. SF #1098985.
1886
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001887- Bug #1077106: Poor argument checking could cause memory corruption
1888 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001889
Jeremy Hyltonab630502005-02-04 18:44:06 +00001890- The parser did not complain about future statements in illegal
1891 positions. It once again reports a syntax error if a future
1892 statement occurs after anything other than a doc string.
1893
Neil Schemenauercf52c072005-08-12 17:34:58 +00001894- Change the %s format specifier for str objects so that it returns a
1895 unicode instance if the argument is not an instance of basestring and
1896 calling __str__ on the argument returns a unicode instance.
1897
Tim Petersf4e69282006-02-27 17:15:31 +00001898- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1899 current thread state when the auto-GIL-state machinery knows about
1900 it (since the thread state is being deleted, continuing to remember it
1901 can't help, but can hurt if another thread happens to get created with
1902 the same thread id).
1903
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001904Extension Modules

1922- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1923
1924- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001925 is deprecated. The undocumented re.engine variable no longer exists.
1926

1929
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001930- The unicodedata module was updated to the 4.1 version of the Unicode
1931 database. The 3.2 version is still available as unicodedata.db_3_2_0
1932 for applications that require this specific version (such as IDNA).
1933
Neal Norwitzb62c4332006-03-04 18:35:47 +00001934- The timing module is no longer built by default. It was deprecated
1935 in PEP 4 in Python 2.0 or earlier.
1936
Guido van Rossum1968ad32006-02-25 22:38:04 +00001937- Patch 1433928: Added a new type, defaultdict, to the collections module.
1938 This uses the new __missing__ hook behavior added to dict (see above).
1939
Georg Brandldbd83392006-02-20 09:42:33 +00001940- Bug #854823: socketmodule now builds on Sun platforms even when

1942
Georg Brandlf4f44152006-02-18 22:29:33 +00001943- Patch #1393157: os.startfile() now has an optional argument to specify
1944 a "command verb" to invoke on the file.
1945
Neal Norwitz082b2df2006-02-07 07:04:46 +00001946- Bug #876637, prevent stack corruption when socket descriptor
1947 is larger than FD_SETSIZE.
1948
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00001949- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
1950 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1951 mmap.mmap(0, size) should not be used on Windows for anonymous memory.

1955
Martin v. Löwis14694662006-02-03 12:54:16 +00001956- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1957 are reported, the limit on path name lengths is removed, and stat reports
1958 WindowsError now (instead of OSError).
1959
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001960- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

2035 the request code argument, which results in more C-like behaviour
2036 for large or negative values.
2037
Tim Petersecc6e6a2005-07-10 22:30:55 +00002038- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002094- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2095 been renamed to have only a single underscore prefix. This was done to
2096 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002097
Nick Coghlan43832302006-04-23 17:04:07 +00002098- PEP 338: new module runpy defines a run_module function to support
2099 executing modules which provide access to source code or a code object
2100 via the PEP 302 import mechanisms.
2101
Anthony Baxter93f5b932006-04-03 08:05:07 +00002102- The email module's parsedate_tz function now sets the daylight savings

2110 in attribute values.
2111
Anthony Baxterc51ee692006-04-01 00:57:31 +00002112- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002113 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002114 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002115 module will not be built.
2116
Tim Petersc17976e2006-04-01 00:26:53 +00002117- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2118 aren't officially supported here, and trying to use them will probably
2119 raise an exception some day. But dicts have been allowed, and "mostly
2120 worked", so support for them won't go away without warning.
2121
Georg Brandl338ef7d2006-03-31 18:42:16 +00002122- Bug #1445068: getpass.getpass() can now be given an explicit stream
2123 argument to specify where to write the prompt.
2124

2140
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002141- email 4.0 package now integrated. This is largely the same as the email 3.0
2142 package that was included in Python 2.3, except that PEP 8 module names are
2143 now used (e.g. mail.message instead of email.Message). The MIME classes
2144 have been moved to a subpackage (e.g. email.mime.text instead of
2145 email.MIMEText). The old names are still supported for now. Several
2146 deprecated Message methods have been removed and lots of bugs have been
2147 fixed. More details can be found in the email package documentation.
2148
Walter Dörwald40108c92006-03-27 08:15:44 +00002149- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2150 (a subclass of tuple) that provides incremental decoders and encoders
2151 (a way to use stateful codecs without the stream API). Python functions
2152 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2153 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2154 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002155
Walter Dörwald067db482006-03-15 22:17:27 +00002156- Patch #1359365: Calling next() on a closed StringIO.String object raises
2157 a ValueError instead of a StopIteration now (like file and cString.String do).
2158 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2159 called before (like file and StringIO.StringIO do).

Tim Peterse3547fd2005-12-16 23:13:57 +00002233 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2234 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2235 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2236 Ronald L. Rivest offered this advice for Python:
2237
2238 "The consensus of researchers in this area (at least as
2239 expressed at the NIST Hash Function Workshop 10/31/05),
2240 is that SHA-256 is a good choice for the time being, but
2241 that research should continue, and other alternatives may
2242 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002243
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002244- Added a subset of Fredrik Lundh's ElementTree package. Available

2306
Guido van Rossum755149f2005-07-27 00:00:44 +00002307- Fix a problem in Tkinter introduced by SF patch #869468: delete bogus
2308 __hasattr__ and __delattr__ methods on class Tk that were breaking
2309 Tkdnd.
2310
Georg Brandl5dbda752005-07-17 20:27:41 +00002311- Bug #1015140: disambiguated the term "article id" in nntplib docs and
2312 docstrings to either "article number" or "message id".
2313
Georg Brandla4a8b822005-07-15 09:13:21 +00002314- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
2315 parameter, but uses the usual "kwargs=None".
2316
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002317- textwrap now processes text chunks at O(n) speed instead of O(n**2).
Raymond Hettinger8bfa8932005-07-15 06:53:35 +00002318 Patch #1209527 (Contributed by Connelly).
2319
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00002320- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
2321 to W3C name (404 -> 'Not Found'). RFE #1216944.
2322
Georg Brandl9e43acf2005-07-04 17:16:07 +00002323- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2324 as this can cause problems with apps closing all file descriptors.
2325
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002326- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002327 it can be missing in embedded interpreters
Georg Brandl5284b532005-06-26 22:54:58 +00002328
Georg Brandl2f210b62005-06-26 22:09:06 +00002329- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
2330
Georg Brandlfbff1bc2005-06-26 21:36:25 +00002331- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
2332 error messages.
2333
Georg Brandl379f99d2005-06-26 21:09:38 +00002334- Bug #1108948: Cookie.py produced invalid JavaScript code.
2335
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00002336- The tokenize module now detects and reports indentation errors.
2337 Bug #1224621.
2338
Raymond Hettinger68c04532005-06-10 11:05:19 +00002339- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002340 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002341 the generate_tokens() function now accepts a callable argument that
2342 terminates by raising StopIteration.
2343
Georg Brandl9166e1a2005-06-04 09:20:03 +00002344- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2345
Georg Brandl268e61c2005-06-03 14:28:50 +00002346- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2347 component of the path.
2348
Skip Montanaro174dd222005-05-14 20:54:16 +00002349- Patch #1120353: The xmlrpclib module provides better, more transparent,
2350 support for datetime.{datetime,date,time} objects. With use_datetime set
2351 to True, applications shouldn't have to fiddle with the DateTime wrapper
2352 class at all.
2353
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002354- distutils.commands.upload was added to support uploading distribution
2355 files to PyPI.
2356
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002357- distutils.commands.register now encodes the data as UTF-8 before posting
2358 them to PyPI.
2359
Raymond Hettinger267b8682005-03-27 10:47:39 +00002360- decimal operator and comparison methods now return NotImplemented
2361 instead of raising a TypeError when interacting with other types. This
2362 allows other classes to implement __radd__ style methods and have them
2363 work as expected.
2364
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002365- Bug #1163325: Decimal infinities failed to hash. Attempting to
2366 hash a NaN raised an InvalidOperation instead of a TypeError.
2367
Tim Petersecc6e6a2005-07-10 22:30:55 +00002368- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002369 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2370

2400
Raymond Hettingerbab41432005-02-05 01:31:19 +00002401- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2402
Guido van Rossumd0641422005-02-03 15:01:24 +00002403- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2404 disables recursive traversal through instance attributes, which can
2405 be exploited in various ways.
2406
Tim Peterse3547fd2005-12-16 23:13:57 +00002407- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002408 flags on the HTTP listening socket.
2409
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002410- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2411 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2412
Fred Drakefbdeaad2006-07-29 16:56:15 +00002413- Patches #893642, #1039083: add allow_none, encoding arguments to
2414 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002415
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002416- Bug #1110478: Revert os.environ.update to do putenv again.
2417
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002418- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2419
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002420- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2421
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002422- Enhancements to the csv module:
2423
2424 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002425 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002426 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002427 + Dialect parameter parsing has been re-implemented to improve error
2428 reporting.
2429 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2430 dictates.
2431 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002432 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002433 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002434 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2435 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002436 + reader now allows \r characters to be quoted (previously it only allowed
2437 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002438 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002439 + Dialect classes passed to the module are no longer instantiated by
2440 the module before being parsed (the former validation scheme required
2441 this, but the mechanism was unreliable).
2442 + The dialect registry now contains instances of the internal
2443 C-coded dialect type, rather than references to python objects.
2444 + the internal c-coded dialect type is now immutable.
2445 + register_dialect now accepts the same keyword dialect specifications
2446 as the reader and writer, allowing the user to register dialects
2447 without first creating a dialect class.
2448 + a configurable limit to the size of parsed fields has been added -
2449 previously, an unmatched quote character could result in the entire
2450 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002451 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002452 the parser field size limit (returning the former limit). The initial
2453 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002454 + A line_num attribute has been added to the reader object, which tracks
2455 the number of lines read from the source iterator. This is not
2456 the same as the number of records returned, as records can span
2457 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002458 + reader and writer objects were not being registered with the cyclic-GC.
2459 This has been fixed.
2460
Brett Cannone6539c42005-01-08 02:43:53 +00002461- _DummyThread objects in the threading module now delete self.__block that is
2462 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2463 lock primitives tend to be limited in number and thus should not be wasted on
2464 a _DummyThread object. Fixes bug #1089632.
2465
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002466- The imghdr module now detects Exif files.
2467
Raymond Hettinger6065d322004-12-20 23:51:53 +00002468- StringIO.truncate() now correctly adjusts the size attribute.
2469 (Bug #951915).
2470
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002471- locale.py now uses an updated locale alias table (built using
2472 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2473 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002474 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002475
Raymond Hettinger3557f422004-12-07 12:02:02 +00002476- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2477
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002478- the pickle module no longer accepts the deprecated None option in the
2479 args tuple returned by __reduce__().
2480
Brett Cannon84667c02004-12-07 03:25:18 +00002481- optparse now optionally imports gettext. This allows its use in setup.py.
2482
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002483- the pickle module no longer uses the deprecated bin parameter.
2484
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002485- the shelve module no longer uses the deprecated binary parameter.
2486
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002487- the pstats module no longer uses the deprecated ignore() method.
2488
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002489- the filecmp module no longer uses the deprecated use_statcache argument.
2490
Raymond Hettinger664347b2004-12-04 21:21:53 +00002491- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2492 extended or overridden by subclasses. Formerly, the subclassed method would
2493 be ignored by the rest of the module. (Bug #1078905).
2494
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002495- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002496 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002497
Walter Dörwald36733692004-12-22 12:50:50 +00002498- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2499 once when a size argument is given. This prevents a buffer overflow in the
2500 tokenizer with very long source lines.
2501
Barry Warsaw538561e2006-01-01 21:48:54 +00002502- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2503 immediately after creating the object, without any intervening
2504 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002505
Skip Montanaro05885812005-01-16 20:48:27 +00002506- The reconvert.quote function can now emit triple-quoted strings. The
2507 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002508
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002509- ``UserString.MutableString`` now supports negative indices in
2510 ``__setitem__`` and ``__delitem__``
2511
Greg Ward40407942005-03-05 02:53:17 +00002512- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2513 correctly.
2514
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002515- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2516 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2517 character even if the user has passed a size parameter to get a proper
2518 line ending. Remove the special handling of a "\r\n" that has been split
2519 between two lines.
2520
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002521- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2522 about illegal code points. The codec now supports PEP 293 style error
2523 handlers.
2524
Walter Dörwald78a78b02005-09-01 12:04:29 +00002525- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002526 from the input stream, so that the output is a byte string in the correct
2527 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002528
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002529- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2530 considering it exactly like a '*'.
2531
Walter Dörwald007f8df2005-10-09 19:42:27 +00002532- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2533 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002534
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002535- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2536
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002537- Patch #1413711: Certain patterns of differences were making difflib
2538 touch the recursion limit.
2539
Walter Dörwald58917a62006-03-31 15:26:22 +00002540- Bug #947906: An object oriented interface has been added to the calendar
2541 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002542 called as a script (e.g. via ``python -mcalendar``). Localized month and
2543 weekday names can be ouput (even if an exotic encoding is used) using
2544 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002545

Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002560- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2561 The zlib module is now builtin on Windows.
2562
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002563- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2564
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002565- Bug #1189330: configure did not correctly determine the necessary
2566 value of LINKCC if python was built with GCC 4.0.
2567
Trent Mick8321b422005-07-26 02:29:21 +00002568- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2569 vulnerability in zlib 1.2.1 and 1.2.2.
2570
Brett Cannon08cd5982005-04-24 22:26:38 +00002571- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2572 flags that change binary compatibility. Changes were also made to
2573 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002574 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002575
Bob Ippolitoed233462005-03-29 13:47:59 +00002576- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2577 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2578 no longer exists). This configure patch makes things right.
2579
Martin v. Löwise2713be2005-03-08 15:03:08 +00002580- Bug #1158607: Build with --disable-unicode again.
2581
Brett Cannon46d96232005-02-16 00:07:19 +00002582- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2583 defined. Discovered as a result of not being able to build on OS X.
2584
Brett Cannon516592f2004-12-07 00:42:59 +00002585- setup.py now uses the directories specified in LDFLAGS using the -L option
2586 and in CPPFLAGS using the -I option for adding library and include
2587 directories, respectively, for compiling extension modules against. This has
2588 led to the core being compiled using the values in CPPFLAGS. It also removes
2589 the need for the special-casing of both DarwinPorts and Fink for darwin since
2590 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2591 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2592 Fink, ``-I/opt/local/include`` for DarwinPorts).
2593
Brett Cannon43802422005-02-10 20:48:03 +00002594- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2595 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2596 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2597 Closes bug #1096244. Thanks Gregory Bond.

2600-----
2601
Tim Petersc9d78aa2006-03-26 23:27:58 +00002602- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2603 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2604 is obtained via the ``PyObject_`` family, it must be released via the
2605 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2606 always been officially true, but when Python's small-object allocator was
2607 introduced, an attempt was made to cater to a few extension modules
2608 discovered at the time that obtained memory via ``PyObject_New`` but
2609 released it via ``PyMem_DEL``. It's years later, and if such code still
2610 exists it will fail now (probably with segfaults, but calling wrong
2611 low-level memory management functions can yield many symptoms).
2612
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002613- Added a C API for set and frozenset objects.
2614

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002617- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2618 mapping argument now. This string is used as a mapping table. Byte values
2619 greater than the length of the string and 0xFFFE are treated as undefined
2620 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002627
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002628- Patch #1276356: New resource "urlfetch" is implemented. This enables
2629 even impatient people to run tests that require remote files.
