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

557Core and builtins
558-----------------
559
Neal Norwitz24b6f202006-09-05 04:43:56 +0000560- Fix infinite recursion when subclassing long and overriding __hash__.
561
562- Fix concatenation (+=) of long strings.
563
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000564- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000565 compared equal or unequal to a string and a UnicodeDecodeError
566 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000567
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000568 Instead, the equal (==) and unequal (!=) comparison operators will
569 now issue a UnicodeWarning and interpret the two objects as
570 unequal. The UnicodeWarning can be filtered as desired using
571 the warning framework, e.g. silenced completely, turned into an
572 exception, logged, etc.
573
574 Note that compare operators other than equal and unequal will still
575 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000576
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000577- Fix segfault when doing string formatting on subclasses of long.

582- Fix bug related to __len__ functions returning negative values with
583 classic classes.
584
585- Patch #1538606, Fix __index__() clipping. There were some problems
586 discovered with the API and how integers that didn't fit into Py_ssize_t
587 were handled. This patch attempts to provide enough alternatives
588 to effectively use __index__.
589
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000590- Bug #1536021: __hash__ may now return long int; the final hash
591 value is obtained by invoking hash on the long int.
592
Thomas Hellerab1049c2006-08-08 17:37:00 +0000593- Bug #1536786: buffer comparison could emit a RuntimeWarning.

596 sys.stdin is closed.
597
Thomas Heller74d36f02006-08-04 18:17:40 +0000598- On Windows, the PyErr_Warn function is now exported from
599 the Python dll again.
600
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000601- Bug #1191458: tracing over for loops now produces a line event
602 on each iteration. Fixing this problem required changing the .pyc
603 magic number. This means that .pyc files generated before 2.5c1
604 will be regenerated.
605
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000606- Bug #1333982: string/number constants were inappropriately stored
607 in the byte code and co_consts even if they were not used, ie
608 immediately popped off the stack.
609
Georg Brandle9462c72006-08-04 18:03:37 +0000610- Fixed a reference-counting problem in property().

614-------
615
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000616- Fix a bug in the ``compiler`` package that caused invalid code to be
617 generated for generator expressions.
618
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000619- The distutils version has been changed to 2.5.0. The change to
620 keep it programmatically in sync with the Python version running
621 the code (introduced in 2.5b3) has been reverted. It will continue
622 to be maintained manually as static string literal.
623
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000624- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000625 and this cannot be converted to the required C type, an exception is
626 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000627 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000628
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000629- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000630 an exception.
631
Tim Peterscbdd3502006-09-05 01:47:53 +0000632- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000633 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000634 workarounds for clocks with low resolution, to stop the code yielding
635 duplicate UUIDs.
636
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000637- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
638 before raising SystemExit, allowing IDLE to honor quit() and exit().
639
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000640- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
641
Georg Brandl7a1af772006-08-14 21:55:28 +0000642- Patch #1536071: trace.py should now find the full module name of a
643 file correctly even on Windows.
644
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000645- logging's atexit hook now runs even if the rest of the module has
646 already been cleaned up.
647
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000648- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000649
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000650- Bug #1531405, format_exception no longer raises an exception if
651 str(exception) raised an exception.
652
Neil Schemenauer06ded092006-08-04 16:20:30 +0000653- Fix a bug in the ``compiler`` package that caused invalid code to be
654 generated for nested functions.

663
Georg Brandl3335a7a2006-08-14 21:42:55 +0000664- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
665 raises the correct exceptions.
666
Thomas Heller1ce433e2006-08-14 16:20:04 +0000667- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
668 '-no-stack-protector' compiler flag for OpenBSD has been removed.
669
Thomas Heller86720042006-08-14 11:17:48 +0000670- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
671 uses the _as_parameter_ attribute when objects are passed to foreign
672 function calls. The ctypes version number was changed to 1.0.1.
673
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000674- Bug #1530559, struct.pack raises TypeError where it used to convert.
675 Passing float arguments to struct.pack when integers are expected
676 now triggers a DeprecationWarning.
677

700-----
701
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +0000702- Bug #1535502, build _hashlib on Windows, and use masm assembler
703 code in OpenSSL.
704
Thomas Hellerdb7b4432006-08-04 19:49:31 +0000705- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

Tim Peters4643c2f2006-08-10 22:45:34 +0000710C API
711-----
712
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000713- New API for Unicode rich comparisons: PyUnicode_RichCompare()
714
Tim Peters4643c2f2006-08-10 22:45:34 +0000715- Bug #1069160. Internal correctness changes were made to
716 ``PyThreadState_SetAsyncExc()``. A test case was added, and
717 the documentation was changed to state that the return value
718 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +0000721What's New in Python 2.5 beta 3?
722================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000723
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000724*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000725
726Core and builtins
727-----------------
728
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000729- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000730 returned a long (see PEP 353).
731
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000732- Bug #1515471: string.replace() accepts character buffers again.
733
Neal Norwitz07aadb12006-07-30 06:55:48 +0000734- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
735 This provides the proper warning for struct.pack().
736 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
737
Neal Norwitz0d62a062006-07-30 06:53:31 +0000738- Patch #1531113: Fix augmented assignment with yield expressions.
739 Also fix a SystemError when trying to assign to yield expressions.
740
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000741- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
742 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
743 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
744 excessive filesystem operations during imports.
745
Tim Petersbc24eee2006-07-27 01:14:53 +0000746- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
747 operations on signed longs that are formally undefined by C.
748 Unfortunately, at least one compiler now cares about that, so complicated
749 the code to make that compiler happy again.
750
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000751- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
752
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000753- Patch #1232023: Stop including current directory in search
754 path on Windows.
755
Neal Norwitze1fdb322006-07-21 05:32:28 +0000756- Fix some potential crashes found with failmalloc.
757
Neal Norwitze7563102006-07-17 01:00:16 +0000758- Fix warnings reported by Klocwork's static analysis tool.
759
Neal Norwitz84be93b2006-07-16 01:50:38 +0000760- Bug #1512814, Fix incorrect lineno's when code within a function
761 had more than 255 blank lines.
762
Georg Brandl9dceedb2006-07-12 15:31:17 +0000763- Patch #1521179: Python now accepts the standard options ``--help`` and
764 ``--version`` as well as ``/?`` on Windows.
765
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000766- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000767 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000768 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000769
Tim Peters112aad32006-07-19 00:03:19 +0000770- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000771 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000772 new ``sys._current_frames()`` returns a dictionary with one entry,
773 mapping the faux "thread id" 0 to the current frame.
774
Ronald Oussoren3075e162006-07-25 20:28:55 +0000775- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000776
Ronald Oussoren3075e162006-07-25 20:28:55 +0000777
Neal Norwitza1f10902006-07-12 07:28:29 +0000778Library
779-------
780
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000781- Correction of patch #1455898: In the mbcs decoder, set final=False
782 for stream decoder, but final=True for the decode function.
783
Georg Brandl07fec3a2006-08-01 18:49:24 +0000784- os.urandom no longer masks unrelated exceptions like SystemExit or
785 KeyboardInterrupt.
786
Tim Peters4643c2f2006-08-10 22:45:34 +0000787- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000788 shutil.copytree on Windows
789
Georg Brandle34ac7c2006-07-30 11:07:23 +0000790- Bug #1002398: The documentation for os.path.sameopenfile now correctly
791 refers to file descriptors, not file objects.
792
Tim Peterscbdd3502006-09-05 01:47:53 +0000793- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000794 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000795 #1513611, and probably others.
796
Georg Brandledd9b0d2006-07-29 09:33:26 +0000797- Bug #1441397: The compiler module now recognizes module and function
798 docstrings correctly as it did in Python 2.4.
799
Tim Peters6f681472006-07-27 23:44:37 +0000800- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
801 lost that tests are sorted by name before being run. This rarely
802 matters for well-written tests, but can create baffling symptoms if
803 side effects from one test to the next affect outcomes. ``DocTestFinder``
804 has been changed to sort the list of tests it returns.
805
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000806- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000807 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000808
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000809- Bug #978833: Really close underlying socket in _socketobject.close.
810
Georg Brandldb232dc2006-08-20 13:15:43 +0000811- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
812 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000813
Georg Brandlcf0c1722006-07-26 07:23:32 +0000814- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
815 to recursive calls and call it with the failing package name.
816
Martin v. Löwis0b483032006-07-25 09:53:12 +0000817- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
818
Georg Brandlc13c34c2006-07-24 14:09:56 +0000819- Patch #1515343: Fix printing of deprecated string exceptions with a
820 value in the traceback module.
821
Greg Ward48fae7a2006-07-23 16:05:51 +0000822- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
823
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000824- Patch #1524429: Use repr() instead of backticks in Tkinter again.
825
Brett Cannoncaebe222006-07-18 04:41:36 +0000826- Bug #1520914: Change time.strftime() to accept a zero for any position in its
827 argument tuple. For arguments where zero is illegal, the value is forced to
828 the minimum value that is correct. This is to support an undocumented but
829 common way people used to fill in inconsequential information in the time
830 tuple pre-2.4.
831
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000832- Patch #1220874: Update the binhex module for Mach-O.
833
Barry Warsawb110bad2006-07-21 14:51:07 +0000834- The email package has improved RFC 2231 support, specifically for
835 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
836 (name*0=<blah>) parameter continuations. This may change the types of
837 values returned from email.message.Message.get_param() and friends.
838 Specifically in some cases where non-encoded continuations were used,
839 get_param() used to return a 3-tuple of (None, None, string) whereas now it
840 will just return the string (since non-encoded continuations don't have
841 charset and language parts).
842
843 Also, whereas % values were decoded in all parameter continuations, they are
844 now only decoded in encoded parameter parts.
845
Ronald Oussoren3075e162006-07-25 20:28:55 +0000846- Bug #1517990: IDLE keybindings on MacOS X now work correctly
847
848- Bug #1517996: IDLE now longer shows the default Tk menu when a
849 path browser, class browser or debugger is the frontmost window on MacOS X
850
Barry Warsaw00decd72006-07-27 23:43:15 +0000851- Patch #1520294: Support for getset and member descriptors in types.py,
852 inspect.py, and pydoc.py. Specifically, this allows for querying the type
853 of an object against these built-in types and more importantly, for getting
854 their docstrings printed in the interactive interpreter's help() function.

858-----------------
859
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000860- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
861 a socket operation on a socket with a timeout, the exception will be
862 caught correctly. Previously, the exception was not caught.
863
Thomas Heller1393d6a2006-07-28 21:43:20 +0000864- Patch #1529514: The _ctypes extension is now compiled on more
865 openbsd target platforms.
866
Tim Peters9cab5932006-07-28 00:30:00 +0000867- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
868 a memory leak, affecting pickles and deep copies.
869
Tim Petersbc24eee2006-07-27 01:14:53 +0000870- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000871 Paul Eggert.
872
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000873- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
874
Thomas Hellerce049a02006-07-14 17:51:14 +0000875- Patch #1521817: Index range checking on ctypes arrays containing
876 exactly one element enabled again. This allows iterating over these
877 arrays, without the need to check the array size before.
878
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000879- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000880 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000881 /dev/null in certain cases; this is now fixed.
882
Thomas Heller47d7a062006-07-12 08:43:47 +0000883- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
884 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000885
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000886- Because of a misspelled preprocessor symbol, ctypes was always
887 compiled without thread support; this is now fixed.
888
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000889- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
890 methods now allow their database parameter to be None as the
891 sleepycat API allows.
892
Matt Flemingec926502006-07-28 11:27:27 +0000893- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
894 bluetooth API compared with Linux and FreeBSD.
895
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000896Tests
897-----
898
899- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
900 how long the test file should take to play. Now accepts taking 2.93 secs
901 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
902
Georg Brandl4793aa32006-07-28 18:31:39 +0000903- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
904 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
905 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +0000912Mac
913---
914
915- PythonLauncher now works correctly when the path to the script contains
916 characters that are treated specially by the shell (such as quotes).
917
918- Bug #1527397: PythonLauncher now launches scripts with the working directory
919 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000920 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000921 expect.

929Core and builtins
930-----------------
931
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000932- Bug #1441486: The literal representation of -(sys.maxint - 1)
933 again evaluates to a int object, not a long.
934
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000935- Bug #1501934: The scope of global variables that are locally assigned
936 using augmented assignment is now correctly determined.
937
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000938- Bug #927248: Recursive method-wrapper objects can now safely
939 be released.
940
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000941- Bug #1417699: Reject locale-specific decimal point in float()
942 and atof().
943
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000944- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
945 omit a default "error" argument for NULL pointer. This allows
946 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000947
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000948- Bug #1519018: 'as' is now validated properly in import statements.
949
Neal Norwitz28746ab2006-07-09 22:14:42 +0000950- On 64 bit systems, int literals that use less than 64 bits are
951 now ints rather than longs.
952
Neal Norwitzed657552006-07-10 00:04:44 +0000953- Bug #1512814, Fix incorrect lineno's when code at module scope
954 started after line 256.
955
Tim Peters32a83612006-07-10 21:08:24 +0000956- New function ``sys._current_frames()`` returns a dict mapping thread
957 id to topmost thread stack frame. This is for expert use, and is
958 especially useful for debugging application deadlocks. The functionality
959 was previously available in Fazal Majid's ``threadframe`` extension
960 module, but it wasn't possible to do this in a wholly threadsafe way from
961 an extension.

970
Tim Peters32a83612006-07-10 21:08:24 +0000971- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000972 environment variable to be set in order to the SDK environment
973 for finding the compiler, include files, etc.
974

Nick Coghlan2d792252006-07-06 13:47:18 +0000977- warnings.py now ignores ImportWarning by default
978
Thomas Woutersadd19112006-07-05 11:03:49 +0000979- string.Template() now correctly handles tuple-values. Previously,
980 multi-value tuples would raise an exception and single-value tuples would
981 be treated as the value they contain, instead.
982
Martin v. Löwisede77f52006-07-03 13:01:35 +0000983- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
984 even if some data are received.
985
Martin v. Löwis45482392006-07-03 12:28:58 +0000986- Bug #1267547: Put proper recursive setup.py call into the
987 spec file generated by bdist_rpm.

990 degrees and radians.
991
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000992- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000993 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000994
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000995- Bug #1514703: Only setup canvas window in turtle when the canvas
996 is created.
997
Martin v. Löwis7596e832006-07-01 15:33:37 +0000998- Bug #1513223: .close() of a _socketobj now releases the underlying
999 socket again, which then gets closed as it becomes unreferenced.

1002 attribute values.
1003
1004- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1005 sgmllib ('[' and ']' were not accepted).
1006
Georg Brandl1be63af2006-06-28 20:23:25 +00001007- Fix a bug in the turtle module's end_fill function.
1008
Brett Cannon53ab5b72006-06-22 16:49:14 +00001009- Bug #1510580: The 'warnings' module improperly required that a Warning
1010 category be either a types.ClassType and a subclass of Warning. The proper
1011 check is just that it is a subclass with Warning as the documentation states.
1012
Georg Brandlad29e632006-06-21 17:45:17 +00001013- The compiler module now correctly compiles the new try-except-finally
1014 statement (bug #1509132).
1015
Neal Norwitz60373cd2006-06-22 06:30:50 +00001016- The wsgiref package is now installed properly on Unix.
1017
Vinay Sajip28e57612006-07-01 10:45:20 +00001018- A bug was fixed in logging.config.fileConfig() which caused a crash on
1019 shutdown when fileConfig() was called multiple times.
1020
Gerhard Häring762fbd32006-07-02 17:48:30 +00001021- The sqlite3 module did cut off data from the SQLite database at the first
1022 null character before sending it to a custom converter. This has been fixed
1023 now.
1024
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001025Extension Modules
1026-----------------
1027
Tim Peters112aad32006-07-19 00:03:19 +00001028- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1029 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1030 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001031
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001032- Assigning None to pointer type fields in ctypes structures possible
1033 overwrote the wrong fields, this is fixed now.
1034
1035- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1036 on non-Windows platforms.
1037
1038- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1039 integer or long, without range checking.
1040
1041- Patch #1517790: It is now possible to use custom objects in the ctypes
1042 foreign function argtypes sequence as long as they provide a from_param
1043 method, no longer is it required that the object is a ctypes type.
1044
1045- The '_ctypes' extension module now works when Python is configured
1046 with the --without-threads option.
1047
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001048- Bug #1513646: os.access on Windows now correctly determines write
1049 access, again.
1050
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001051- Bug #1512695: cPickle.loads could crash if it was interrupted with
1052 a KeyboardInterrupt.
1053
Neal Norwitza12aa882006-07-06 06:45:08 +00001054- Bug #1296433: parsing XML with a non-default encoding and
1055 a CharacterDataHandler could crash the interpreter in pyexpat.
1056
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001057- Patch #1516912: improve Modules support for OpenVMS.
1058
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001059Build
1060-----
1061
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001062- Automate Windows build process for the Win64 SSL module.
1063
Tim Peters32a83612006-07-10 21:08:24 +00001064- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001065 Previously, the slight difference could cause compilation errors of the
1066 'zlib' module on systems with more than one version of zlib.
1067
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001068- The MSI compileall step was fixed to also support a TARGETDIR
1069 with spaces in it.
1070
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001071- Bug #1517388: sqlite3.dll is now installed on Windows independent
1072 of Tcl/Tk.
1073
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001074- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001075 trying to be installed even though it's empty.

Neal Norwitzb15ac312006-06-29 04:10:08 +00001077Tests
1078-----
1079
1080- Call os.waitpid() at the end of tests that spawn child processes in order
1081 to minimize resources (zombies).
1082
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001083Documentation
1084-------------
1085
Nick Coghlan2d792252006-07-06 13:47:18 +00001086- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1087 documentation for the warnings module.
1088
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001089- Patch #1509163: MS Toolkit Compiler no longer available.
1090
Neal Norwitz56640df2006-07-10 02:36:41 +00001091- Patch #1504046: Add documentation for xml.etree.

1100-----------------
1101
Georg Brandla56b9152006-06-19 06:35:54 +00001102- Patch #1507676: Error messages returned by invalid abstract object operations
1103 (such as iterating over an integer) have been improved and now include the
1104 type of the offending object to help with debugging.
1105
Brett Cannonea3912b2006-06-13 21:46:41 +00001106- Bug #992017: A classic class that defined a __coerce__() method that returned
1107 its arguments swapped would infinitely recurse and segfault the interpreter.
1108
Neal Norwitz909eb122006-06-12 02:13:21 +00001109- Fix the socket tests so they can be run concurrently.
1110
Neal Norwitzb9845e72006-06-12 02:11:18 +00001111- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001112 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001113
Brett Cannon22565aa2006-06-09 22:31:23 +00001114- Bug #532646: object.__call__() will continue looking for the __call__
1115 attribute on objects until one without one is found. This leads to recursion
1116 when you take a class and set its __call__ attribute to an instance of the
1117 class. Originally fixed for classic classes, but this fix is for new-style.
1118 Removes the infinite_rec_3 crasher.
1119
Georg Brandl24250812006-06-09 18:45:48 +00001120- The string and unicode methods startswith() and endswith() now accept
1121 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1122
Brett Cannonde3b0522006-06-08 17:00:45 +00001123- Buffer objects, at the C level, never used the char buffer
1124 implementation even when the char buffer for the wrapped object was
1125 explicitly requested (originally returned the read or write buffer).
1126 Now a TypeError is raised if the char buffer is not present but is
1127 requested.
1128
Georg Brandlddbaa662006-06-04 21:56:52 +00001129- Patch #1346214: Statements like "if 0: suite" are now again optimized
1130 away like they were in Python 2.4.
1131
Georg Brandlb7c8f542006-05-27 12:30:25 +00001132- Builtin exceptions are now full-blown new-style classes instead of
1133 instances pretending to be classes, which speeds up exception handling
1134 by about 80% in comparison to 2.5a2.
1135
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001136- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1137 Unicode 4.1.
1138
Georg Brandlf4ef1162006-05-26 18:03:31 +00001139- Patch #921466: sys.path_importer_cache is now used to cache valid and
1140 invalid file paths for the built-in import machinery which leads to
1141 fewer open calls on startup.
1142
Tim Peters696cf432006-05-24 21:10:40 +00001143- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1144 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1145 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1146 the number of input digits (it was and remains linear-time for bases
1147 2, 4, 8, 16 and 32).
1148
Tim Petersb713ec22006-05-23 18:45:30 +00001149- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1150 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1151 an integer close to ``sys.maxint``. This was repaired by patch
1152 #1335972, which also gives a nice speedup.
1153
Richard Jonescebbefc2006-05-23 18:28:17 +00001154- Patch #1337051: reduced size of frame objects.
1155
1156- PyErr_NewException now accepts a tuple of base classes as its
1157 "base" parameter.
1158
Richard Jones7c88dcc2006-05-23 10:37:38 +00001159- Patch #876206: function call speedup by retaining allocated frame
1160 objects.
1161
Georg Brandl7b90e162006-05-18 07:01:27 +00001162- Bug #1462152: file() now checks more thoroughly for invalid mode
1163 strings and removes a possible "U" before passing the mode to the
1164 C library function.
1165
Neal Norwitz1004a532006-05-15 07:17:23 +00001166- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1167
Neal Norwitz373f0a72006-05-15 07:04:36 +00001168- Bug #1487966: Fix SystemError with conditional expression in assignment
1169
Martin v. Löwis879768d2006-05-11 13:28:43 +00001170- WindowsError now has two error code attributes: errno, which carries
1171 the error values from errno.h, and winerror, which carries the error
1172 values from winerror.h. Previous versions put the winerror.h values
1173 (from GetLastError()) into the errno attribute.
1174
Martin v. Löwis77736712006-05-04 05:51:03 +00001175- Patch #1475845: Raise IndentationError for unexpected indent.
1176
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001177- Patch #1479181: split open() and file() from being aliases for each other.
1178
Tim Peters44bd9862006-06-01 13:49:23 +00001179- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1180 methods were always silently ignored by dictionaries when comparing keys.
1181 They are now passed through (except when using the C API function
1182 ``PyDict_GetItem()``, whose semantics did not change).
1183
1184- Bug #1456209: In some obscure cases it was possible for a class with a
1185 custom ``__eq__()`` method to confuse dict internals when class instances
1186 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1187 No, you don't have any code that did this ;-)

1195
Brett Cannon6ee7d012006-06-08 16:23:04 +00001196- Change binascii.hexlify to accept a read-only buffer instead of only a char
1197 buffer and actually follow its documentation.
1198
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001199- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1200
Nick Coghlanc649ec52006-05-29 12:43:05 +00001201- Patch #1478788 (modified version): The functional extension module has
1202 been renamed to _functools and a functools Python wrapper module added.
1203 This provides a home for additional function related utilities that are
1204 not specifically about functional programming. See PEP 309.
1205
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001206- Patch #1493701: performance enhancements for struct module.
1207
Georg Brandl378d5922006-05-17 14:26:50 +00001208- Patch #1490224: time.altzone is now set correctly on Cygwin.
1209
Georg Brandl8d3342b2006-05-16 07:38:27 +00001210- Patch #1435422: zlib's compress and decompress objects now have a
1211 copy() method.
1212
Andrew MacIntyre92913322006-06-13 15:04:24 +00001213- Patch #1454481: thread stack size is now tunable at runtime for thread
1214 enabled builds on Windows and systems with Posix threads support.
1215
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001216- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1217 (up to the system limit of 32K characters).
1218
1219- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1220 As a result, these functions now raise WindowsError instead of OSError.
1221
Tim Peters7a822da2006-05-25 21:50:17 +00001222- ``time.clock()`` on Win64 should use the high-performance Windows
1223 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1224 Windows platforms).
1225
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001226- Calling Tk_Init twice is refused if the first call failed as that
1227 may deadlock.
1228
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001229- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1230 accept it without potentially using an uninitialized pointer.
1231
1232- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1233 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1234 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001235
Gregory P. Smith372b5832006-06-05 18:48:21 +00001236- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001237 [pybsddb project SF patch number 1466734]
1238
Gregory P. Smith372b5832006-06-05 18:48:21 +00001239- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1240 parameter is supplied. [SF pybsddb bug #1477863]
1241
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001242- bsddb: the __len__ method of a DB object has been fixed to return correct
1243 results. It could previously incorrectly return 0 in some cases.
1244 Fixes SF bug 1493322 (pybsddb bug 1184012).
1245
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001246- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1247 aborts the db transaction safely when a modifier callback fails.
1248 Fixes SF python patch/bug #1408584.
1249
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001250- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001251 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001252 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1253 database calls that would previously deadlock. [SF python bug #775414]
1254
Vinay Sajip28e57612006-07-01 10:45:20 +00001255- Patch #1446489: add support for the ZIP64 extensions to zipfile.

Georg Brandl83cc0d02006-06-14 08:50:03 +00001276- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1277 mime.types file for determining MIME types.
1278
Georg Brandl2605ca82006-06-14 06:08:31 +00001279- Bug #1339007: Shelf objects now don't raise an exception in their
1280 __del__ method when initialization failed.
1281
Martin v. Löwisd8251432006-06-14 05:21:04 +00001282- Patch #1455898: The MBCS codec now supports the incremental mode for
1283 double-byte encodings.
1284
Tim Peters43898b42006-06-14 04:09:25 +00001285- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1286 guarantee that adjacent triples in the return list always describe
1287 non-adjacent blocks. Previously, a pair of matching blocks could end
1288 up being described by multiple adjacent triples that formed a partition
1289 of the matching pair.
1290
Greg Ward0e0c9f42006-06-11 16:24:11 +00001291- Bug #1498146: fix optparse to handle Unicode strings in option help,
1292 description, and epilog.
1293
Greg Wardd1c797e2006-06-11 14:42:41 +00001294- Bug #1366250: minor optparse documentation error.
1295
Greg Ward7f547402006-06-11 00:40:49 +00001296- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1297 clarify docs.
1298
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001299- The wsgiref package has been added to the standard library.
1300
Nick Coghlan676725d2006-06-08 13:54:49 +00001301- The functions update_wrapper() and wraps() have been added to the functools
1302 module. These make it easier to copy relevant metadata from the original
1303 function when writing wrapper functions.
1304
Tim Petersd6a9eef2006-06-05 01:48:21 +00001305- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1306 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001307
Martin v. Löwis3f767792006-06-04 19:36:28 +00001308- Patch #1359618: Speed up charmap encoder by using a trie structure
1309 for lookup.
1310
Tim Petersd609b1a2006-06-02 23:22:51 +00001311- The functions in the ``pprint`` module now sort dictionaries by key
1312 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1313 if and only if its display required more than one line, although that
1314 wasn't documented. The new behavior increases predictability; e.g.,
1315 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1316
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001317- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1318 (thanks for J. J. Lee).
1319
Georg Brandl2b330372006-05-28 20:23:12 +00001320- Patch #1496206: improve urllib2 handling of passwords with respect to
1321 default HTTP and HTTPS ports.
1322
George Yoshidaf3c65de2006-05-28 16:39:09 +00001323- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1324
Bob Ippolito7298f272006-05-23 18:43:47 +00001325- Patch #1281707: speed up gzip.readline.
1326
Georg Brandlb89316f2006-05-17 15:51:16 +00001327- Patch #1180296: Two new functions were added to the locale module:
1328 format_string() to get the effect of "format % items" but locale-aware,
1329 and currency() to format a monetary number with currency sign.
1330
Georg Brandle3a25832006-05-17 14:56:04 +00001331- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1332 and several features added, such as speed and geometry control.
1333
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001334- Patch #1488881: add support for external file objects in bz2 compressed
1335 tarfiles.
1336
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001337- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1338 stdout arguments, making it possible to redirect input and output
1339 for remote debugging.
1340
1341- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1342 a couple of issues, notably handling of long file names using the
1343 GNU LONGNAME extension.
1344
1345- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1346 new flag when ``name`` is already the name of an option flag.
1347
1348- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1349 package.
1350
1351- Patch #1472854: make the rlcompleter.Completer class usable on non-
1352 UNIX platforms.
1353
1354- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1355
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001356- Bug #1472827: correctly escape newlines and tabs in attribute values in
1357 the saxutils.XMLGenerator class.

1393-----------------
1394
Thomas Heller1b046642006-04-18 18:51:06 +00001395- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1396 by converting these apis from macros into exported functions again:
1397
1398 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1399 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1400 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1401 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1402 PyRun_String Py_CompileString
1403
Martin v. Löwis45294a92006-04-18 06:24:08 +00001404- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1405
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001406- All uses of PyStructSequence_InitType have been changed to initialize
1407 the type objects only once, even if the interpreter is initialized
1408 multiple times.
1409
Neal Norwitz61546162006-04-14 05:20:28 +00001410- Bug #1454485, array.array('u') could crash the interpreter. This was
1411 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1412 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1413
1414- Py_UNICODE is unsigned. It was always documented as unsigned, but
1415 due to a bug had a signed value in previous versions.
1416
Tim Peters3a5e8b12006-04-11 01:44:07 +00001417- Patch #837242: ``id()`` of any Python object always gives a positive
1418 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1419 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001420 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001421 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001422
Tim Peters3a5e8b12006-04-11 01:44:07 +00001423 def __hash__(self):
1424 return id(self) # WRONG
1425
1426 because a hash result must be a (short) Python int but it was always
1427 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001428 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001429 was always usable as a hash value before this patch. That's no longer
1430 necessarily so.
1431
1432- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001433 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001434 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001435 #1454844)
1436
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001437- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1438 involving generators that have paused outside of any ``try`` or ``with``
1439 blocks. (In 2.5a1, a paused generator that was part of a reference
1440 cycle could not be garbage collected, regardless of whether it was
1441 paused in a ``try`` or ``with`` block.)

1453
1454- Bug #1117761: bsddb.*open() no longer raises an exception when using
1455 the cachesize parameter.
1456
1457- Bug #1149413: bsddb.*open() no longer raises an exception when using
1458 a temporary db (file=None) with the 'n' flag to truncate on open.
1459
1460- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1461 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001462
Armin Rigoa9017c32006-04-19 11:50:27 +00001463- Patch #1062014: AF_UNIX sockets under Linux have a special
1464 abstract namespace that is now fully supported.

1467-------
1468
Peter Astrand7d1d4362006-07-14 14:04:45 +00001469- Bug #1223937: subprocess.CalledProcessError reports the exit status
1470 of the process using the returncode attribute, instead of
1471 abusing errno.
1472
Tim Peters711bf302006-04-25 03:31:36 +00001473- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1474 a doctest to be skipped (the code is not run, and the expected output
1475 or exception is ignored).
1476
Nick Coghlanda2268f2006-04-24 04:37:15 +00001477- Fixed contextlib.nested to cope with exceptions being raised and
1478 caught inside exit handlers.
1479
Greg Wardab05edc2006-04-23 03:47:58 +00001480- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1481 hex, octal, or binary; add ``append_const`` action; keep going if
1482 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1483 added ``epilog`` for better help generation).
1484
Tim Peters21fbd572006-04-21 21:18:10 +00001485- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1486 called from a thread spawned as a side effect of importing a module.
1487
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001488- The pydoc module now supports documenting packages contained in
1489 .zip or .egg files.
1490
1491- The pkgutil module now has several new utility functions, such
1492 as ``walk_packages()`` to support working with packages that are either
1493 in the filesystem or zip files.
1494
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001495- The mailbox module can now modify and delete messages from
1496 mailboxes, in addition to simply reading them. Thanks to Gregory
1497 K. Johnson for writing the code, and to the 2005 Google Summer of
1498 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001499
Tim Petersc7605f22006-04-17 21:12:33 +00001500- The ``__del__`` method of class ``local`` in module ``_threading_local``
1501 returned before accomplishing any of its intended cleanup.
1502

1522
Skip Montanaro262fb922006-04-21 02:31:07 +00001523- The pstats.Stats class accepts an optional stream keyword argument to
1524 direct output to an alternate file-like object.
1525
Anthony Baxter51bcb682006-04-05 14:51:42 +00001526Build
1527-----
1528
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001529- The Makefile now has a reindent target, which runs reindent.py on
1530 the library.
1531
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001532- Patch #1470875: Building Python with MS Free Compiler
1533
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001534- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001535
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001536- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1537 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001538 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001539 CXX from --with-cxx-main, see description in README.
1540
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001541- Patch #1429775: Link extension modules with the shared libpython.
1542
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001543- Fixed a libffi build problem on MIPS systems.
1544
Tim Peters8931ff12006-05-13 23:28:20 +00001545- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1546 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1547 and "%zu" for unsigned integers of type ``size_t``.
1548
Anthony Baxter51bcb682006-04-05 14:51:42 +00001549Tests
1550-----
1551
Nick Coghlanda2268f2006-04-24 04:37:15 +00001552- test_contextlib now checks contextlib.nested can cope with exceptions
1553 being raised and caught inside exit handlers.
1554
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001555- test_cmd_line now checks operation of the -m and -c command switches
1556
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001557- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1558 it separately and by hand. It also wasn't cleaning up its changes to
1559 the current Decimal context.
1560
Thomas Woutersabd08882006-04-26 15:53:30 +00001561- regrtest.py now has a -M option to run tests that test the new limits of
1562 containers, on 64-bit architectures. Running these tests is only sensible
1563 on 64-bit machines with more than two gigabytes of memory. The argument
1564 passed is the maximum amount of memory for the tests to use.
1565
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001566Tools

Anthony Baxter51bcb682006-04-05 14:51:42 +00001572Documentation
1573-------------
1574
Tim Petersb06d28c2006-05-12 01:57:59 +00001575- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1576
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001577- PEP 343: Added Context Types section to the library reference
1578 and attempted to bring other PEP 343 related documentation into
1579 line with the implementation and/or python-dev discussions.
1580
Tim Peters8dc73d22006-04-24 02:03:16 +00001581- Bug #1337990: clarified that ``doctest`` does not support examples
1582 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001585What's New in Python 2.5 alpha 1?
1586=================================
1587
Anthony Baxterebed3f62006-04-03 15:03:44 +00001588*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001589
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001590Core and builtins
1591-----------------
1592
Nick Coghlan43832302006-04-23 17:04:07 +00001593- PEP 338: -m command line switch now delegates to runpy.run_module
1594 allowing it to support modules in packages and zipfiles
1595
Martin v. Löwisc661b882006-04-20 04:54:23 +00001596- On Windows, .DLL is not an accepted file name extension for
1597 extension modules anymore; extensions are only found if they
1598 end in .PYD.
1599
Martin v. Löwisea62d252006-04-03 10:56:49 +00001600- Bug #1421664: sys.stderr.encoding is now set to the same value as
1601 sys.stdout.encoding.
1602
Neal Norwitz92e212f2006-04-03 04:48:37 +00001603- __import__ accepts keyword arguments.
1604
Georg Brandlccadf842006-03-31 18:54:53 +00001605- Patch #1460496: round() now accepts keyword arguments.
1606
Anthony Baxter262c00a2006-03-30 10:53:17 +00001607- Fixed bug #1459029 - unicode reprs were double-escaped.
1608
Hye-Shik Changd478f342006-03-23 12:32:36 +00001609- Patch #1396919: The system scope threads are reenabled on FreeBSD
1610 5.4 and later versions.
1611
Neal Norwitze98ccf62006-03-23 05:39:47 +00001612- Bug #1115379: Compiling a Unicode string with an encoding declaration
1613 now gives a SyntaxError.
1614
Georg Brandlabd1ff82006-03-18 07:59:59 +00001615- Previously, Python code had no easy way to access the contents of a
1616 cell object. Now, a ``cell_contents`` attribute has been added
1617 (closes patch #1170323).
1618
Tim Peterscf79aac2006-03-16 01:14:46 +00001619- Patch #1123430: Python's small-object allocator now returns an arena to
1620 the system ``free()`` when all memory within an arena becomes unused
1621 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1622 freed. Some applications will see a drop in virtual memory size now,
1623 especially long-running applications that, from time to time, temporarily
1624 use a large number of small objects. Note that when Python returns an
1625 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001626 platform C library will in turn return that memory to the operating system.
1627 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001628 appears to be effective at least on Microsoft C and gcc-based systems.
1629 Thanks to Evan Jones for hard work and patience.
1630
Georg Brandl533ff6f2006-03-08 18:09:27 +00001631- Patch #1434038: property() now uses the getter's docstring if there is
1632 no "doc" argument given. This makes it possible to legitimately use
1633 property() as a decorator to produce a read-only property.
1634
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001635- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1636 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1637 of requiring an int or long in slicing and a few other contexts, enabling
1638 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1639
Neal Norwitz995acdf2006-03-07 05:01:00 +00001640- Fixed various bugs reported by Coverity's Prevent tool.
1641
Brett Cannonbf364092006-03-01 04:25:17 +00001642- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1643 new exception base class, BaseException, which has a new message attribute.
1644 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1645 Raising a string exception now raises a DeprecationWarning.
1646
Thomas Woutersfb609f42006-02-28 16:37:25 +00001647- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1648 explicitly relative, using 'from .module import name' to mean 'from the same
1649 package as this module is in. Imports without dots still default to the
1650 old relative-then-absolute, unless 'from __future__ import
1651 absolute_import' is used.
1652
Brett Cannona7446e32006-02-27 23:39:10 +00001653- Properly check if 'warnings' raises an exception (usually when a filter set
1654 to "error" is triggered) when raising a warning for raising string
1655 exceptions.
1656
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001657- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001658 The name was removed from Include/code.h.
1659
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001660- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001661
Guido van Rossum1968ad32006-02-25 22:38:04 +00001662- Patch 1433928:
1663 - The copy module now "copies" function objects (as atomic objects).
1664 - dict.__getitem__ now looks for a __missing__ hook before raising
1665 KeyError.
1666
Tim Peters84ef21c2006-02-28 20:39:06 +00001667- PEP 343: with statement implemented. Needs ``from __future__ import
1668 with_statement``. Use of 'with' as a variable will generate a warning.
1669 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001670 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001671 The following objects have __context__ methods:
1672 - The built-in file type.
1673 - The thread.LockType type.
1674 - The following types defined by the threading module:
1675 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1676 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001677
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001678- Fix the encodings package codec search function to only search
1679 inside its own package. Fixes problem reported in patch #1433198.
1680
1681 Note: Codec packages should implement and register their own
1682 codec search function. PEP 100 has the details.
1683
Tim Peters9ea89d22006-06-04 03:26:02 +00001684- PEP 353: Using ``Py_ssize_t`` as the index type.
1685
1686- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1687 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1688 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1689 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1690 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001691
Neal Norwitzfc76d632006-01-10 06:03:13 +00001692- Patch #1400181, fix unicode string formatting to not use the locale.
1693 This is how string objects work. u'%f' could use , instead of .
1694 for the decimal point. Now both strings and unicode always use periods.
1695
Neal Norwitz671b9e32006-01-09 07:07:12 +00001696- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1697 configure would break checking curses.h.
1698
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001699- Bug #959576: The pwd module is now builtin. This allows Python to be
1700 built on UNIX platforms without $HOME set.
1701
Neal Norwitzc10978f2005-12-19 06:07:16 +00001702- Bug #1072182, fix some potential problems if characters are signed.
1703
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001704- Bug #889500, fix line number on SyntaxWarning for global declarations.
1705
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001706- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1707
Neal Norwitze7214a12005-12-18 05:03:17 +00001708- Support for converting hex strings to floats no longer works.
1709 This was not portable. float('0x3') now raises a ValueError.
1710
Barry Warsaw2a38a862005-12-18 01:27:35 +00001711- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001712 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001713 is now displayed in interactive prompt banner.
1714
Georg Brandlfa166682005-12-17 21:45:17 +00001715- Implementation of PEP 341 - Unification of try/except and try/finally.
1716 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001717 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001718
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001719- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1720 now encodes backslash correctly.
1721
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001722- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1723
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001724- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001725 and long longs.
1726
Neal Norwitz67715f02005-11-09 06:59:35 +00001727- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001728 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001729 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001730
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001731- Replaced most Unicode charmap codecs with new ones using the
1732 new Unicode translate string feature in the builtin charmap
1733 codec; the codecs were created from the mapping tables available
1734 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1735 encodings now include a mapping for the Apple logo)
1736
Tim Peterse3547fd2005-12-16 23:13:57 +00001737- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001738
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001739- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001740
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001741- A new AST parser implementation was completed. The abstract
1742 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001743 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001744
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001745- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001746 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1747
Neal Norwitz708e51a2005-10-03 04:48:15 +00001748- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1749
Neal Norwitz11bd1192005-10-03 00:54:56 +00001750- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1751 Provide a warning when a directory is passed on the command line.
1752
Neal Norwitz40d37812005-10-02 01:48:49 +00001753- Fix segfault with invalid coding.
1754
1755- SF bug #772896: unknown encoding results in MemoryError.
1756
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001757- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001758 supported a __len__() method which evaluated to False when the iterator
1759 was empty.
1760
Guido van Rossum630db602005-09-20 18:49:54 +00001761- On 64-bit platforms, when __len__() returns a value that cannot be
1762 represented as a C int, raise OverflowError.
1763
Skip Montanarof8948ca2005-09-19 03:54:46 +00001764- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001765 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001766
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001767- SF bug #893549: parsing keyword arguments was broken with a few format
1768 codes.
1769
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001770- Changes donated by Elemental Security to make it work on AIX 5.3
1771 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1772 bug #105470: test_pwd fails on 64bit system (Opteron).
1773
Guido van Rossum539c6622005-09-14 17:49:54 +00001774- Changes donated by Elemental Security to make it work on HP-UX 11 on
1775 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1776
Georg Brandl4550b8d2005-08-26 06:43:52 +00001777- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001778 (fixes bug #1119418).
1779
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001780- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1781
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001782- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1783 exceptions that cause a function to exit.
1784
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001785- The implementation of set() and frozenset() was revised to use its
1786 own internal data structure. Memory consumption is reduced by 1/3
1787 and there are modest speed-ups as well. The API is unchanged.
1788
Tim Petersde7990b2005-07-17 23:45:23 +00001789- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1790
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001791- SF bug #1229429: PyObject_CallMethod failed to decrement some
1792 reference counts in some error exit cases.
1793
Tim Petersecc6e6a2005-07-10 22:30:55 +00001794- SF bug #1185883: Python's small-object memory allocator took over
1795 a block managed by the platform C library whenever a realloc specified
1796 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001797 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001798 portable way to copy data from the C-managed block into Python's
1799 small-object space without risking a memory fault. Python's small-object
1800 realloc now leaves such blocks under the control of the platform C
1801 realloc.
1802
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001803- SF bug #1232517: An overflow error was not detected properly when
1804 attempting to convert a large float to an int in os.utime().
1805
Raymond Hettinger3296e692005-06-29 23:29:56 +00001806- SF bug #1224347: hex longs now print with lowercase letters just
1807 like their int counterparts.
1808
Michael W. Hudson188d4362005-06-20 16:52:57 +00001809- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1810 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1811 interpreter states; back out that fix and do a better job (see
1812 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1813 for a longer write-up of the problem).
1814
Michael W. Hudsondf888462005-06-03 14:41:55 +00001815- SF patch #1180995: marshal now uses a binary format by default when
1816 serializing floats.
1817
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001818- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1819 the routines that promise to produce IEEE 754 binary representations
1820 of floats now simply copy bytes around.
1821
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001822- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1823 278.
1824
Brett Cannonc3647ac2005-04-26 03:45:26 +00001825- patch #1109424: int, long, float, complex, and unicode now check for the
1826 proper magic slot for type conversions when subclassed. Previously the
1827 magic slot was ignored during conversion. Semantics now match the way
1828 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001829 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001830 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001831 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001832
Barry Warsawc8d907c2005-04-19 23:43:40 +00001833- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1834 NULL, now raise an AttributeError when attempting to set or delete the
1835 attribute. Previously a TypeError was raised, but this was inconsistent
1836 with the equivalent pure-Python implementation.
1837
Michael W. Hudson774479c2005-04-18 08:46:17 +00001838- It is now safe to call PyGILState_Release() before
1839 PyEval_InitThreads() (note that if there is reason to believe there
1840 are multiple threads around you still must call PyEval_InitThreads()
1841 before using the Python API; this fix is for extension modules that
1842 have no way of knowing if Python is multi-threaded yet).
1843
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001844- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1845 disabled caused a crash.
1846
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001847- Bug #1165306: instancemethod_new allowed the creation of a method
1848 with im_class == im_self == NULL, which caused a crash when called.
1849
Tim Petersecc6e6a2005-07-10 22:30:55 +00001850- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001851 fixes the crash seen in bug #1165761
1852
Raymond Hettinger96229b12005-03-11 06:49:40 +00001853- Added two new builtins, any() and all().
1854
Brett Cannon409d8f22005-03-05 06:47:57 +00001855- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001856 (e.g., ``class C(): pass`` is no longer a syntax error).
1857 Patch #1176012 added support to the 'parser' module and 'compiler' package
1858 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001859
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001860- Patch #1115086: Support PY_LONGLONG in structmember.
1861
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001862- Bug #1155938: new style classes did not check that __init__() was
1863 returning None.
1864
Tim Petersecc6e6a2005-07-10 22:30:55 +00001865- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001866 ('\') with a specific error message.
1867
Martin v. Löwisff232d72005-03-03 09:24:38 +00001868- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1869
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001870- Bug #1124295: the __name__ attribute of file objects was
1871 inadvertently made inaccessible in restricted mode.
1872
Tim Petersecc6e6a2005-07-10 22:30:55 +00001873- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001874 an ferror() call.
1875
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001876- min() and max() now support key= arguments with the same meaning as in
1877 list.sort().
1878
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001879- The peephole optimizer now performs simple constant folding in expressions:
1880 (2+3) --> (5).
1881
Raymond Hettingera422c342005-01-11 03:03:27 +00001882- set and frozenset objects can now be marshalled. SF #1098985.
1883
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001884- Bug #1077106: Poor argument checking could cause memory corruption
1885 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001886
Jeremy Hyltonab630502005-02-04 18:44:06 +00001887- The parser did not complain about future statements in illegal
1888 positions. It once again reports a syntax error if a future
1889 statement occurs after anything other than a doc string.
1890
Neil Schemenauercf52c072005-08-12 17:34:58 +00001891- Change the %s format specifier for str objects so that it returns a
1892 unicode instance if the argument is not an instance of basestring and
1893 calling __str__ on the argument returns a unicode instance.
1894
Tim Petersf4e69282006-02-27 17:15:31 +00001895- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1896 current thread state when the auto-GIL-state machinery knows about
1897 it (since the thread state is being deleted, continuing to remember it
1898 can't help, but can hurt if another thread happens to get created with
1899 the same thread id).

1926
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001927- The unicodedata module was updated to the 4.1 version of the Unicode
1928 database. The 3.2 version is still available as unicodedata.db_3_2_0
1929 for applications that require this specific version (such as IDNA).
1930
Neal Norwitzb62c4332006-03-04 18:35:47 +00001931- The timing module is no longer built by default. It was deprecated
1932 in PEP 4 in Python 2.0 or earlier.
1933
Guido van Rossum1968ad32006-02-25 22:38:04 +00001934- Patch 1433928: Added a new type, defaultdict, to the collections module.
1935 This uses the new __missing__ hook behavior added to dict (see above).
1936
Georg Brandldbd83392006-02-20 09:42:33 +00001937- Bug #854823: socketmodule now builds on Sun platforms even when

1939
Georg Brandlf4f44152006-02-18 22:29:33 +00001940- Patch #1393157: os.startfile() now has an optional argument to specify
1941 a "command verb" to invoke on the file.
1942

1952
Martin v. Löwis14694662006-02-03 12:54:16 +00001953- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1954 are reported, the limit on path name lengths is removed, and stat reports
1955 WindowsError now (instead of OSError).
1956
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001957- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

2032 the request code argument, which results in more C-like behaviour
2033 for large or negative values.
2034
Tim Petersecc6e6a2005-07-10 22:30:55 +00002035- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002091- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2092 been renamed to have only a single underscore prefix. This was done to
2093 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002094
Nick Coghlan43832302006-04-23 17:04:07 +00002095- PEP 338: new module runpy defines a run_module function to support
2096 executing modules which provide access to source code or a code object
2097 via the PEP 302 import mechanisms.
2098
Anthony Baxter93f5b932006-04-03 08:05:07 +00002099- The email module's parsedate_tz function now sets the daylight savings

2107 in attribute values.
2108
Anthony Baxterc51ee692006-04-01 00:57:31 +00002109- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002110 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002111 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002112 module will not be built.
2113
Tim Petersc17976e2006-04-01 00:26:53 +00002114- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2115 aren't officially supported here, and trying to use them will probably
2116 raise an exception some day. But dicts have been allowed, and "mostly
2117 worked", so support for them won't go away without warning.
2118
Georg Brandl338ef7d2006-03-31 18:42:16 +00002119- Bug #1445068: getpass.getpass() can now be given an explicit stream
2120 argument to specify where to write the prompt.
2121

2131 to make it easier to monitor when daemon threads have completed
2132 processing all enqueued tasks. Patch #1455676.
2133

2137
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002138- email 4.0 package now integrated. This is largely the same as the email 3.0
2139 package that was included in Python 2.3, except that PEP 8 module names are
2140 now used (e.g. mail.message instead of email.Message). The MIME classes
2141 have been moved to a subpackage (e.g. email.mime.text instead of
2142 email.MIMEText). The old names are still supported for now. Several
2143 deprecated Message methods have been removed and lots of bugs have been
2144 fixed. More details can be found in the email package documentation.
2145
Walter Dörwald40108c92006-03-27 08:15:44 +00002146- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2147 (a subclass of tuple) that provides incremental decoders and encoders
2148 (a way to use stateful codecs without the stream API). Python functions
2149 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2150 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2151 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002152
Walter Dörwald067db482006-03-15 22:17:27 +00002153- Patch #1359365: Calling next() on a closed StringIO.String object raises
2154 a ValueError instead of a StopIteration now (like file and cString.String do).
2155 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2156 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002157
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002158- A regrtest option -w was added to re-run failed tests in verbose mode.

Tim Peterse3547fd2005-12-16 23:13:57 +00002230 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2231 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2232 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2233 Ronald L. Rivest offered this advice for Python:
2234
2235 "The consensus of researchers in this area (at least as
2236 expressed at the NIST Hash Function Workshop 10/31/05),
2237 is that SHA-256 is a good choice for the time being, but
2238 that research should continue, and other alternatives may
2239 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002240
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002241- Added a subset of Fredrik Lundh's ElementTree package. Available

2306 Tkdnd.
2307
Georg Brandl5dbda752005-07-17 20:27:41 +00002308- Bug #1015140: disambiguated the term "article id" in nntplib docs and
2309 docstrings to either "article number" or "message id".
2310
Georg Brandla4a8b822005-07-15 09:13:21 +00002311- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
2312 parameter, but uses the usual "kwargs=None".
2313
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002314- textwrap now processes text chunks at O(n) speed instead of O(n**2).
Raymond Hettinger8bfa8932005-07-15 06:53:35 +00002315 Patch #1209527 (Contributed by Connelly).
2316
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00002317- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
2318 to W3C name (404 -> 'Not Found'). RFE #1216944.
2319
Georg Brandl9e43acf2005-07-04 17:16:07 +00002320- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2321 as this can cause problems with apps closing all file descriptors.
2322
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002323- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002324 it can be missing in embedded interpreters
Georg Brandl5284b532005-06-26 22:54:58 +00002325
Georg Brandl2f210b62005-06-26 22:09:06 +00002326- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
2327
Georg Brandlfbff1bc2005-06-26 21:36:25 +00002328- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
2329 error messages.
2330
Georg Brandl379f99d2005-06-26 21:09:38 +00002331- Bug #1108948: Cookie.py produced invalid JavaScript code.
2332
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00002333- The tokenize module now detects and reports indentation errors.
2334 Bug #1224621.
2335
Raymond Hettinger68c04532005-06-10 11:05:19 +00002336- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002337 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002338 the generate_tokens() function now accepts a callable argument that
2339 terminates by raising StopIteration.
2340
Georg Brandl9166e1a2005-06-04 09:20:03 +00002341- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2342
Georg Brandl268e61c2005-06-03 14:28:50 +00002343- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2344 component of the path.
2345
Skip Montanaro174dd222005-05-14 20:54:16 +00002346- Patch #1120353: The xmlrpclib module provides better, more transparent,
2347 support for datetime.{datetime,date,time} objects. With use_datetime set
2348 to True, applications shouldn't have to fiddle with the DateTime wrapper
2349 class at all.
2350
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002351- distutils.commands.upload was added to support uploading distribution
2352 files to PyPI.
2353
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002354- distutils.commands.register now encodes the data as UTF-8 before posting
2355 them to PyPI.
2356
Raymond Hettinger267b8682005-03-27 10:47:39 +00002357- decimal operator and comparison methods now return NotImplemented
2358 instead of raising a TypeError when interacting with other types. This
2359 allows other classes to implement __radd__ style methods and have them
2360 work as expected.
2361
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002362- Bug #1163325: Decimal infinities failed to hash. Attempting to
2363 hash a NaN raised an InvalidOperation instead of a TypeError.
2364
Tim Petersecc6e6a2005-07-10 22:30:55 +00002365- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002366 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2367

2399
Guido van Rossumd0641422005-02-03 15:01:24 +00002400- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2401 disables recursive traversal through instance attributes, which can
2402 be exploited in various ways.
2403
Tim Peterse3547fd2005-12-16 23:13:57 +00002404- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002405 flags on the HTTP listening socket.
2406
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002407- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2408 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2409
Fred Drakefbdeaad2006-07-29 16:56:15 +00002410- Patches #893642, #1039083: add allow_none, encoding arguments to
2411 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002412
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002413- Bug #1110478: Revert os.environ.update to do putenv again.
2414
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002415- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2416
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002417- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2418
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002419- Enhancements to the csv module:
2420
2421 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002422 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002423 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002424 + Dialect parameter parsing has been re-implemented to improve error
2425 reporting.
2426 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2427 dictates.
2428 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002429 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002430 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002431 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2432 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002433 + reader now allows \r characters to be quoted (previously it only allowed
2434 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002435 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002436 + Dialect classes passed to the module are no longer instantiated by
2437 the module before being parsed (the former validation scheme required
2438 this, but the mechanism was unreliable).
2439 + The dialect registry now contains instances of the internal
2440 C-coded dialect type, rather than references to python objects.
2441 + the internal c-coded dialect type is now immutable.
2442 + register_dialect now accepts the same keyword dialect specifications
2443 as the reader and writer, allowing the user to register dialects
2444 without first creating a dialect class.
2445 + a configurable limit to the size of parsed fields has been added -
2446 previously, an unmatched quote character could result in the entire
2447 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002448 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002449 the parser field size limit (returning the former limit). The initial
2450 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002451 + A line_num attribute has been added to the reader object, which tracks
2452 the number of lines read from the source iterator. This is not
2453 the same as the number of records returned, as records can span
2454 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002455 + reader and writer objects were not being registered with the cyclic-GC.
2456 This has been fixed.
2457
Brett Cannone6539c42005-01-08 02:43:53 +00002458- _DummyThread objects in the threading module now delete self.__block that is
2459 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2460 lock primitives tend to be limited in number and thus should not be wasted on
2461 a _DummyThread object. Fixes bug #1089632.
2462
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002463- The imghdr module now detects Exif files.
2464
Raymond Hettinger6065d322004-12-20 23:51:53 +00002465- StringIO.truncate() now correctly adjusts the size attribute.
2466 (Bug #951915).
2467
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002468- locale.py now uses an updated locale alias table (built using
2469 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2470 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002471 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002472
Raymond Hettinger3557f422004-12-07 12:02:02 +00002473- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2474
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002475- the pickle module no longer accepts the deprecated None option in the
2476 args tuple returned by __reduce__().
2477
Brett Cannon84667c02004-12-07 03:25:18 +00002478- optparse now optionally imports gettext. This allows its use in setup.py.
2479
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002480- the pickle module no longer uses the deprecated bin parameter.
2481
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002482- the shelve module no longer uses the deprecated binary parameter.
2483
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002484- the pstats module no longer uses the deprecated ignore() method.
2485
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002486- the filecmp module no longer uses the deprecated use_statcache argument.
2487
Raymond Hettinger664347b2004-12-04 21:21:53 +00002488- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2489 extended or overridden by subclasses. Formerly, the subclassed method would
2490 be ignored by the rest of the module. (Bug #1078905).
2491
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002492- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002493 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002494
Walter Dörwald36733692004-12-22 12:50:50 +00002495- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2496 once when a size argument is given. This prevents a buffer overflow in the
2497 tokenizer with very long source lines.
2498
Barry Warsaw538561e2006-01-01 21:48:54 +00002499- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2500 immediately after creating the object, without any intervening
2501 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002502
Skip Montanaro05885812005-01-16 20:48:27 +00002503- The reconvert.quote function can now emit triple-quoted strings. The
2504 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002505
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002506- ``UserString.MutableString`` now supports negative indices in
2507 ``__setitem__`` and ``__delitem__``
2508
Greg Ward40407942005-03-05 02:53:17 +00002509- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2510 correctly.
2511
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002512- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2513 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2514 character even if the user has passed a size parameter to get a proper
2515 line ending. Remove the special handling of a "\r\n" that has been split
2516 between two lines.
2517
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002518- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2519 about illegal code points. The codec now supports PEP 293 style error
2520 handlers.
2521
Walter Dörwald78a78b02005-09-01 12:04:29 +00002522- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002523 from the input stream, so that the output is a byte string in the correct
2524 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002525
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002526- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2527 considering it exactly like a '*'.
2528
Walter Dörwald007f8df2005-10-09 19:42:27 +00002529- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2530 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002531
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002532- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2533
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002534- Patch #1413711: Certain patterns of differences were making difflib
2535 touch the recursion limit.
2536
Walter Dörwald58917a62006-03-31 15:26:22 +00002537- Bug #947906: An object oriented interface has been added to the calendar
2538 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002539 called as a script (e.g. via ``python -mcalendar``). Localized month and
2540 weekday names can be ouput (even if an exotic encoding is used) using
2541 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002542

Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002560- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2561
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002562- Bug #1189330: configure did not correctly determine the necessary
2563 value of LINKCC if python was built with GCC 4.0.
2564
Trent Mick8321b422005-07-26 02:29:21 +00002565- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2566 vulnerability in zlib 1.2.1 and 1.2.2.
2567
Brett Cannon08cd5982005-04-24 22:26:38 +00002568- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2569 flags that change binary compatibility. Changes were also made to
2570 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002571 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002572
Bob Ippolitoed233462005-03-29 13:47:59 +00002573- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2574 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2575 no longer exists). This configure patch makes things right.
2576
Martin v. Löwise2713be2005-03-08 15:03:08 +00002577- Bug #1158607: Build with --disable-unicode again.
2578
Brett Cannon46d96232005-02-16 00:07:19 +00002579- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2580 defined. Discovered as a result of not being able to build on OS X.
2581
Brett Cannon516592f2004-12-07 00:42:59 +00002582- setup.py now uses the directories specified in LDFLAGS using the -L option
2583 and in CPPFLAGS using the -I option for adding library and include
2584 directories, respectively, for compiling extension modules against. This has
2585 led to the core being compiled using the values in CPPFLAGS. It also removes
2586 the need for the special-casing of both DarwinPorts and Fink for darwin since
2587 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2588 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2589 Fink, ``-I/opt/local/include`` for DarwinPorts).
2590
Brett Cannon43802422005-02-10 20:48:03 +00002591- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2592 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2593 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2594 Closes bug #1096244. Thanks Gregory Bond.

2597-----
2598
Tim Petersc9d78aa2006-03-26 23:27:58 +00002599- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2600 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2601 is obtained via the ``PyObject_`` family, it must be released via the
2602 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2603 always been officially true, but when Python's small-object allocator was
2604 introduced, an attempt was made to cater to a few extension modules
2605 discovered at the time that obtained memory via ``PyObject_New`` but
2606 released it via ``PyMem_DEL``. It's years later, and if such code still
2607 exists it will fail now (probably with segfaults, but calling wrong
2608 low-level memory management functions can yield many symptoms).
2609
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002610- Added a C API for set and frozenset objects.
2611

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002614- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2615 mapping argument now. This string is used as a mapping table. Byte values
2616 greater than the length of the string and 0xFFFE are treated as undefined
2617 mappings.

Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002625- Patch #1276356: New resource "urlfetch" is implemented. This enables
2626 even impatient people to run tests that require remote files.
