103
Brett Cannon9adeab72006-09-20 18:34:28 +0000104- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
105 allows calling unicode() on exceptions classes directly to succeed.
106
Georg Brandlec6c2df2006-09-11 09:38:35 +0000107- Make _PyGILState_NoteThreadState() static, it was not used anywhere

125 head is the original string if sep was not found.
126
Neal Norwitzdac090d2006-09-05 03:53:08 +0000127- Bug #1520864: unpacking singleton tuples in list comprehensions and
128 generator expressions (x for x, in ... ) works again. Fixing this problem
129 required changing the .pyc magic number. This means that .pyc files

Jeremy Hyltoncca75402007-02-27 18:33:31 +0000136- Add new requirements for metaclasses. 1) If type or a subclass of type
137 occurs in __bases__, it must occur before any non-type bases, e.g.
138 before regular classes. 2) If you assign to __bases__, you may not
139 change the metaclass. Many more illegal assignments to __bases__
140 are now checked and raise TypeErrors. This changed fixed at least
141 one known crash.

600Core and builtins
601-----------------
602
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000603- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000604 compared equal or unequal to a string and a UnicodeDecodeError
605 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000606
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000607 Instead, the equal (==) and unequal (!=) comparison operators will
608 now issue a UnicodeWarning and interpret the two objects as
609 unequal. The UnicodeWarning can be filtered as desired using
610 the warning framework, e.g. silenced completely, turned into an
611 exception, logged, etc.
612
613 Note that compare operators other than equal and unequal will still
614 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000615
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000616- Fix segfault when doing string formatting on subclasses of long.
617
618- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
619 with new-style classes.
620
621- Fix bug related to __len__ functions returning negative values with
622 classic classes.
623
624- Patch #1538606, Fix __index__() clipping. There were some problems
625 discovered with the API and how integers that didn't fit into Py_ssize_t
626 were handled. This patch attempts to provide enough alternatives
627 to effectively use __index__.
628
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000629- Bug #1536021: __hash__ may now return long int; the final hash
630 value is obtained by invoking hash on the long int.
631
Thomas Hellerab1049c2006-08-08 17:37:00 +0000632- Bug #1536786: buffer comparison could emit a RuntimeWarning.
633
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000634- Bug #1535165: fixed a segfault in input() and raw_input() when
635 sys.stdin is closed.
636
Thomas Heller74d36f02006-08-04 18:17:40 +0000637- On Windows, the PyErr_Warn function is now exported from
638 the Python dll again.
639
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000640- Bug #1191458: tracing over for loops now produces a line event
641 on each iteration. Fixing this problem required changing the .pyc
642 magic number. This means that .pyc files generated before 2.5c1
643 will be regenerated.
644
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000645- Bug #1333982: string/number constants were inappropriately stored
646 in the byte code and co_consts even if they were not used, ie
647 immediately popped off the stack.
648
Georg Brandle9462c72006-08-04 18:03:37 +0000649- Fixed a reference-counting problem in property().
650

652Library
653-------
654
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000655- Fix a bug in the ``compiler`` package that caused invalid code to be
656 generated for generator expressions.
657
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000658- The distutils version has been changed to 2.5.0. The change to
659 keep it programmatically in sync with the Python version running
660 the code (introduced in 2.5b3) has been reverted. It will continue
661 to be maintained manually as static string literal.
662
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000663- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000664 and this cannot be converted to the required C type, an exception is
665 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000666 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000667
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000668- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000669 an exception.
670
Tim Petersc10c9d02006-09-05 02:18:09 +0000671- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000672 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000673 workarounds for clocks with low resolution, to stop the code yielding
674 duplicate UUIDs.
675
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000676- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
677 before raising SystemExit, allowing IDLE to honor quit() and exit().
678
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000679- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
680
Georg Brandl7a1af772006-08-14 21:55:28 +0000681- Patch #1536071: trace.py should now find the full module name of a
682 file correctly even on Windows.
683
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000684- logging's atexit hook now runs even if the rest of the module has
685 already been cleaned up.
686
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000687- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000688
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000689- Bug #1531405, format_exception no longer raises an exception if
690 str(exception) raised an exception.
691
Neil Schemenauer06ded092006-08-04 16:20:30 +0000692- Fix a bug in the ``compiler`` package that caused invalid code to be
693 generated for nested functions.
694
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000695
696Extension Modules
697-----------------
698
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000699- Patch #1511317: don't crash on invalid hostname (alias) info.
700
Georg Brandl3335a7a2006-08-14 21:42:55 +0000701- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
702 raises the correct exceptions.
703
Thomas Heller1ce433e2006-08-14 16:20:04 +0000704- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
705 '-no-stack-protector' compiler flag for OpenBSD has been removed.
706
Thomas Heller86720042006-08-14 11:17:48 +0000707- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
708 uses the _as_parameter_ attribute when objects are passed to foreign
709 function calls. The ctypes version number was changed to 1.0.1.
710
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000711- Bug #1530559, struct.pack raises TypeError where it used to convert.
712 Passing float arguments to struct.pack when integers are expected
713 now triggers a DeprecationWarning.
714
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000715
716Tests
717-----
718
Neal Norwitzb476fdf2006-08-15 04:58:28 +0000719- test_socketserver should now work on cygwin and not fail sporadically
720 on other platforms.

723
Georg Brandl9908d162006-08-06 07:06:33 +0000724- Bug #1535182: really test the xreadlines() method of bz2 objects.
725
Andrew MacIntyre16ee33a2006-08-06 12:37:03 +0000726- test_threading now skips testing alternate thread stack sizes on
727 platforms that don't support changing thread stack size.
728
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000729
Georg Brandl212b5872006-08-05 06:10:54 +0000730Documentation
731-------------
732
733- Patch #1534922: unittest docs were corrected and enhanced.
734
735
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000736Build
737-----
738
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +0000739- Bug #1535502, build _hashlib on Windows, and use masm assembler
740 code in OpenSSL.
741
Thomas Hellerdb7b4432006-08-04 19:49:31 +0000742- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000744- Bug #1530448, ctypes build failure on Solaris 10 was fixed.
Thomas Heller17984892006-08-04 18:57:34 +0000745
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000746
Tim Peters4643c2f2006-08-10 22:45:34 +0000747C API
748-----
749
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000750- New API for Unicode rich comparisons: PyUnicode_RichCompare()
751
Tim Peters4643c2f2006-08-10 22:45:34 +0000752- Bug #1069160. Internal correctness changes were made to
753 ``PyThreadState_SetAsyncExc()``. A test case was added, and
754 the documentation was changed to state that the return value
755 is always 1 (normal) or 0 (if the specified thread wasn't found).

Neal Norwitza1f10902006-07-12 07:28:29 +0000762
763Core and builtins
764-----------------
765
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000766- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000767 returned a long (see PEP 353).
768
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000769- Bug #1515471: string.replace() accepts character buffers again.
770
Neal Norwitz07aadb12006-07-30 06:55:48 +0000771- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
772 This provides the proper warning for struct.pack().
773 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
774
Neal Norwitz0d62a062006-07-30 06:53:31 +0000775- Patch #1531113: Fix augmented assignment with yield expressions.
776 Also fix a SystemError when trying to assign to yield expressions.
777
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000778- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
779 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
780 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
781 excessive filesystem operations during imports.
782
Tim Petersbc24eee2006-07-27 01:14:53 +0000783- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
784 operations on signed longs that are formally undefined by C.
785 Unfortunately, at least one compiler now cares about that, so complicated
786 the code to make that compiler happy again.
787
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000788- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
789
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000790- Patch #1232023: Stop including current directory in search
791 path on Windows.
792
Neal Norwitze1fdb322006-07-21 05:32:28 +0000793- Fix some potential crashes found with failmalloc.
794
Neal Norwitze7563102006-07-17 01:00:16 +0000795- Fix warnings reported by Klocwork's static analysis tool.
796
Neal Norwitz84be93b2006-07-16 01:50:38 +0000797- Bug #1512814, Fix incorrect lineno's when code within a function
798 had more than 255 blank lines.
799
Georg Brandl9dceedb2006-07-12 15:31:17 +0000800- Patch #1521179: Python now accepts the standard options ``--help`` and
801 ``--version`` as well as ``/?`` on Windows.
802
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000803- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000804 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000805 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000806
Tim Peters112aad32006-07-19 00:03:19 +0000807- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000808 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000809 new ``sys._current_frames()`` returns a dictionary with one entry,
810 mapping the faux "thread id" 0 to the current frame.
811
Ronald Oussoren3075e162006-07-25 20:28:55 +0000812- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000813
Ronald Oussoren3075e162006-07-25 20:28:55 +0000814
Neal Norwitza1f10902006-07-12 07:28:29 +0000815Library
816-------
817
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000818- Correction of patch #1455898: In the mbcs decoder, set final=False
819 for stream decoder, but final=True for the decode function.
820
Georg Brandl07fec3a2006-08-01 18:49:24 +0000821- os.urandom no longer masks unrelated exceptions like SystemExit or
822 KeyboardInterrupt.
823
Tim Peters4643c2f2006-08-10 22:45:34 +0000824- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000825 shutil.copytree on Windows
826
Georg Brandle34ac7c2006-07-30 11:07:23 +0000827- Bug #1002398: The documentation for os.path.sameopenfile now correctly
828 refers to file descriptors, not file objects.
829
Tim Petersc10c9d02006-09-05 02:18:09 +0000830- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000831 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000832 #1513611, and probably others.
833
Georg Brandledd9b0d2006-07-29 09:33:26 +0000834- Bug #1441397: The compiler module now recognizes module and function
835 docstrings correctly as it did in Python 2.4.
836
Tim Peters6f681472006-07-27 23:44:37 +0000837- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
838 lost that tests are sorted by name before being run. This rarely
839 matters for well-written tests, but can create baffling symptoms if
840 side effects from one test to the next affect outcomes. ``DocTestFinder``
841 has been changed to sort the list of tests it returns.
842
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000843- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000844 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000845
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000846- Bug #978833: Really close underlying socket in _socketobject.close.
847
Georg Brandl8c036cc2006-08-20 13:15:39 +0000848- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
849 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000850
Georg Brandlcf0c1722006-07-26 07:23:32 +0000851- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
852 to recursive calls and call it with the failing package name.
853
Martin v. Löwis0b483032006-07-25 09:53:12 +0000854- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
855
Georg Brandlc13c34c2006-07-24 14:09:56 +0000856- Patch #1515343: Fix printing of deprecated string exceptions with a
857 value in the traceback module.
858
Greg Ward48fae7a2006-07-23 16:05:51 +0000859- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
860
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000861- Patch #1524429: Use repr() instead of backticks in Tkinter again.
862
Brett Cannoncaebe222006-07-18 04:41:36 +0000863- Bug #1520914: Change time.strftime() to accept a zero for any position in its
864 argument tuple. For arguments where zero is illegal, the value is forced to
865 the minimum value that is correct. This is to support an undocumented but
866 common way people used to fill in inconsequential information in the time
867 tuple pre-2.4.
868
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000869- Patch #1220874: Update the binhex module for Mach-O.
870
Barry Warsawb110bad2006-07-21 14:51:07 +0000871- The email package has improved RFC 2231 support, specifically for
872 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
873 (name*0=<blah>) parameter continuations. This may change the types of
874 values returned from email.message.Message.get_param() and friends.
875 Specifically in some cases where non-encoded continuations were used,
876 get_param() used to return a 3-tuple of (None, None, string) whereas now it
877 will just return the string (since non-encoded continuations don't have
878 charset and language parts).
879
880 Also, whereas % values were decoded in all parameter continuations, they are
881 now only decoded in encoded parameter parts.
882
Ronald Oussoren3075e162006-07-25 20:28:55 +0000883- Bug #1517990: IDLE keybindings on MacOS X now work correctly
884
885- Bug #1517996: IDLE now longer shows the default Tk menu when a
886 path browser, class browser or debugger is the frontmost window on MacOS X
887
Barry Warsaw00decd72006-07-27 23:43:15 +0000888- Patch #1520294: Support for getset and member descriptors in types.py,
889 inspect.py, and pydoc.py. Specifically, this allows for querying the type
890 of an object against these built-in types and more importantly, for getting

895-----------------
896
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000897- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
898 a socket operation on a socket with a timeout, the exception will be
899 caught correctly. Previously, the exception was not caught.
900
Thomas Heller1393d6a2006-07-28 21:43:20 +0000901- Patch #1529514: The _ctypes extension is now compiled on more
902 openbsd target platforms.
903
Tim Peters9cab5932006-07-28 00:30:00 +0000904- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
905 a memory leak, affecting pickles and deep copies.
906
Tim Petersbc24eee2006-07-27 01:14:53 +0000907- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000908 Paul Eggert.
909
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000910- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
911
Thomas Hellerce049a02006-07-14 17:51:14 +0000912- Patch #1521817: Index range checking on ctypes arrays containing
913 exactly one element enabled again. This allows iterating over these
914 arrays, without the need to check the array size before.
915
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000916- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000917 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000918 /dev/null in certain cases; this is now fixed.
919
Thomas Heller47d7a062006-07-12 08:43:47 +0000920- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
921 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000922
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000923- Because of a misspelled preprocessor symbol, ctypes was always
924 compiled without thread support; this is now fixed.
925
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000926- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
927 methods now allow their database parameter to be None as the
928 sleepycat API allows.
929
Matt Flemingec926502006-07-28 11:27:27 +0000930- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
931 bluetooth API compared with Linux and FreeBSD.
932
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000933Tests
934-----
935
936- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
937 how long the test file should take to play. Now accepts taking 2.93 secs
938 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
939
Georg Brandl4793aa32006-07-28 18:31:39 +0000940- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
941 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
942 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +0000943
Martin v. Löwis0907f4d2006-07-30 14:09:47 +0000944Build
945-----
946
947- Bug #1439538: Drop usage of test -e in configure as it is not portable.
948
Ronald Oussoren26cad082006-08-01 21:00:57 +0000949Mac
950---
951
952- PythonLauncher now works correctly when the path to the script contains
953 characters that are treated specially by the shell (such as quotes).
954
955- Bug #1527397: PythonLauncher now launches scripts with the working directory
956 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000957 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000958 expect.

966Core and builtins
967-----------------
968
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000969- Bug #1441486: The literal representation of -(sys.maxint - 1)
970 again evaluates to a int object, not a long.
971
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000972- Bug #1501934: The scope of global variables that are locally assigned
973 using augmented assignment is now correctly determined.
974
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000975- Bug #927248: Recursive method-wrapper objects can now safely
976 be released.
977
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000978- Bug #1417699: Reject locale-specific decimal point in float()
979 and atof().
980
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000981- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
982 omit a default "error" argument for NULL pointer. This allows
983 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000984
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000985- Bug #1519018: 'as' is now validated properly in import statements.
986
Neal Norwitz28746ab2006-07-09 22:14:42 +0000987- On 64 bit systems, int literals that use less than 64 bits are
988 now ints rather than longs.
989
Neal Norwitzed657552006-07-10 00:04:44 +0000990- Bug #1512814, Fix incorrect lineno's when code at module scope
991 started after line 256.
992
Tim Peters32a83612006-07-10 21:08:24 +0000993- New function ``sys._current_frames()`` returns a dict mapping thread
994 id to topmost thread stack frame. This is for expert use, and is
995 especially useful for debugging application deadlocks. The functionality
996 was previously available in Fazal Majid's ``threadframe`` extension
997 module, but it wasn't possible to do this in a wholly threadsafe way from
998 an extension.

1015
Thomas Woutersadd19112006-07-05 11:03:49 +00001016- string.Template() now correctly handles tuple-values. Previously,
1017 multi-value tuples would raise an exception and single-value tuples would
1018 be treated as the value they contain, instead.
1019
Martin v. Löwisede77f52006-07-03 13:01:35 +00001020- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1021 even if some data are received.
1022
Martin v. Löwis45482392006-07-03 12:28:58 +00001023- Bug #1267547: Put proper recursive setup.py call into the

1027 degrees and radians.
1028
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001029- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001030 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001031
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001032- Bug #1514703: Only setup canvas window in turtle when the canvas
1033 is created.
1034
Martin v. Löwis7596e832006-07-01 15:33:37 +00001035- Bug #1513223: .close() of a _socketobj now releases the underlying

1039 attribute values.
1040
1041- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1042 sgmllib ('[' and ']' were not accepted).
1043
Georg Brandl1be63af2006-06-28 20:23:25 +00001044- Fix a bug in the turtle module's end_fill function.
1045
Brett Cannon53ab5b72006-06-22 16:49:14 +00001046- Bug #1510580: The 'warnings' module improperly required that a Warning
1047 category be either a types.ClassType and a subclass of Warning. The proper
1048 check is just that it is a subclass with Warning as the documentation states.
1049
Georg Brandlad29e632006-06-21 17:45:17 +00001050- The compiler module now correctly compiles the new try-except-finally
1051 statement (bug #1509132).
1052
Neal Norwitz60373cd2006-06-22 06:30:50 +00001053- The wsgiref package is now installed properly on Unix.
1054
Vinay Sajip28e57612006-07-01 10:45:20 +00001055- A bug was fixed in logging.config.fileConfig() which caused a crash on
1056 shutdown when fileConfig() was called multiple times.
1057
Gerhard Häring762fbd32006-07-02 17:48:30 +00001058- The sqlite3 module did cut off data from the SQLite database at the first
1059 null character before sending it to a custom converter. This has been fixed
1060 now.
1061
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001062Extension Modules
1063-----------------
1064
Tim Peters112aad32006-07-19 00:03:19 +00001065- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1066 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1067 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001068
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001069- Assigning None to pointer type fields in ctypes structures possible
1070 overwrote the wrong fields, this is fixed now.
1071
1072- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1073 on non-Windows platforms.
1074
1075- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1076 integer or long, without range checking.
1077
1078- Patch #1517790: It is now possible to use custom objects in the ctypes
1079 foreign function argtypes sequence as long as they provide a from_param
1080 method, no longer is it required that the object is a ctypes type.
1081
1082- The '_ctypes' extension module now works when Python is configured
1083 with the --without-threads option.
1084
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001085- Bug #1513646: os.access on Windows now correctly determines write
1086 access, again.
1087
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001088- Bug #1512695: cPickle.loads could crash if it was interrupted with
1089 a KeyboardInterrupt.
1090
Neal Norwitza12aa882006-07-06 06:45:08 +00001091- Bug #1296433: parsing XML with a non-default encoding and
1092 a CharacterDataHandler could crash the interpreter in pyexpat.
1093
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001094- Patch #1516912: improve Modules support for OpenVMS.
1095
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001096Build
1097-----
1098
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001099- Automate Windows build process for the Win64 SSL module.
1100
Tim Peters32a83612006-07-10 21:08:24 +00001101- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001102 Previously, the slight difference could cause compilation errors of the
1103 'zlib' module on systems with more than one version of zlib.
1104
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001105- The MSI compileall step was fixed to also support a TARGETDIR
1106 with spaces in it.
1107
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001108- Bug #1517388: sqlite3.dll is now installed on Windows independent

1116
1117- Call os.waitpid() at the end of tests that spawn child processes in order
1118 to minimize resources (zombies).

Martin v. Löwis1bf59592006-06-29 18:58:44 +00001120Documentation
1121-------------
1122
Nick Coghlan2d792252006-07-06 13:47:18 +00001123- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1124 documentation for the warnings module.
1125
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001126- Patch #1509163: MS Toolkit Compiler no longer available.

1137-----------------
1138
Georg Brandla56b9152006-06-19 06:35:54 +00001139- Patch #1507676: Error messages returned by invalid abstract object operations
1140 (such as iterating over an integer) have been improved and now include the
1141 type of the offending object to help with debugging.
1142
Brett Cannonea3912b2006-06-13 21:46:41 +00001143- Bug #992017: A classic class that defined a __coerce__() method that returned
1144 its arguments swapped would infinitely recurse and segfault the interpreter.
1145
Neal Norwitz909eb122006-06-12 02:13:21 +00001146- Fix the socket tests so they can be run concurrently.
1147
Neal Norwitzb9845e72006-06-12 02:11:18 +00001148- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001149 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001150
Brett Cannon22565aa2006-06-09 22:31:23 +00001151- Bug #532646: object.__call__() will continue looking for the __call__
1152 attribute on objects until one without one is found. This leads to recursion
1153 when you take a class and set its __call__ attribute to an instance of the
1154 class. Originally fixed for classic classes, but this fix is for new-style.
1155 Removes the infinite_rec_3 crasher.
1156
Georg Brandl24250812006-06-09 18:45:48 +00001157- The string and unicode methods startswith() and endswith() now accept
1158 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1159
Brett Cannonde3b0522006-06-08 17:00:45 +00001160- Buffer objects, at the C level, never used the char buffer
1161 implementation even when the char buffer for the wrapped object was
1162 explicitly requested (originally returned the read or write buffer).
1163 Now a TypeError is raised if the char buffer is not present but is
1164 requested.
1165
Georg Brandlddbaa662006-06-04 21:56:52 +00001166- Patch #1346214: Statements like "if 0: suite" are now again optimized
1167 away like they were in Python 2.4.
1168
Georg Brandlb7c8f542006-05-27 12:30:25 +00001169- Builtin exceptions are now full-blown new-style classes instead of
1170 instances pretending to be classes, which speeds up exception handling
1171 by about 80% in comparison to 2.5a2.
1172
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001173- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1174 Unicode 4.1.
1175
Georg Brandlf4ef1162006-05-26 18:03:31 +00001176- Patch #921466: sys.path_importer_cache is now used to cache valid and
1177 invalid file paths for the built-in import machinery which leads to
1178 fewer open calls on startup.
1179
Tim Peters696cf432006-05-24 21:10:40 +00001180- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1181 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1182 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1183 the number of input digits (it was and remains linear-time for bases
1184 2, 4, 8, 16 and 32).
1185
Tim Petersb713ec22006-05-23 18:45:30 +00001186- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1187 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1188 an integer close to ``sys.maxint``. This was repaired by patch
1189 #1335972, which also gives a nice speedup.

Richard Jonescebbefc2006-05-23 18:28:17 +00001191- Patch #1337051: reduced size of frame objects.
1192
1193- PyErr_NewException now accepts a tuple of base classes as its
1194 "base" parameter.
1195
Richard Jones7c88dcc2006-05-23 10:37:38 +00001196- Patch #876206: function call speedup by retaining allocated frame
1197 objects.
1198
Georg Brandl7b90e162006-05-18 07:01:27 +00001199- Bug #1462152: file() now checks more thoroughly for invalid mode
1200 strings and removes a possible "U" before passing the mode to the
1201 C library function.
1202
Neal Norwitz1004a532006-05-15 07:17:23 +00001203- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1204
Neal Norwitz373f0a72006-05-15 07:04:36 +00001205- Bug #1487966: Fix SystemError with conditional expression in assignment
1206
Martin v. Löwis879768d2006-05-11 13:28:43 +00001207- WindowsError now has two error code attributes: errno, which carries
1208 the error values from errno.h, and winerror, which carries the error
1209 values from winerror.h. Previous versions put the winerror.h values
1210 (from GetLastError()) into the errno attribute.
1211
Martin v. Löwis77736712006-05-04 05:51:03 +00001212- Patch #1475845: Raise IndentationError for unexpected indent.
1213
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001214- Patch #1479181: split open() and file() from being aliases for each other.
1215
Tim Peters44bd9862006-06-01 13:49:23 +00001216- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1217 methods were always silently ignored by dictionaries when comparing keys.
1218 They are now passed through (except when using the C API function
1219 ``PyDict_GetItem()``, whose semantics did not change).
1220
1221- Bug #1456209: In some obscure cases it was possible for a class with a
1222 custom ``__eq__()`` method to confuse dict internals when class instances
1223 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1224 No, you don't have any code that did this ;-)

1227-----------------
1228
Trent Mick960a3f82006-06-28 20:30:41 +00001229- Bug #1295808: expat symbols should be namespaced in pyexpat
1230
1231- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1232
Brett Cannon6ee7d012006-06-08 16:23:04 +00001233- Change binascii.hexlify to accept a read-only buffer instead of only a char
1234 buffer and actually follow its documentation.
1235
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001236- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1237
Nick Coghlanc649ec52006-05-29 12:43:05 +00001238- Patch #1478788 (modified version): The functional extension module has
1239 been renamed to _functools and a functools Python wrapper module added.
1240 This provides a home for additional function related utilities that are
1241 not specifically about functional programming. See PEP 309.
1242
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001243- Patch #1493701: performance enhancements for struct module.
1244
Georg Brandl378d5922006-05-17 14:26:50 +00001245- Patch #1490224: time.altzone is now set correctly on Cygwin.
1246
Georg Brandl8d3342b2006-05-16 07:38:27 +00001247- Patch #1435422: zlib's compress and decompress objects now have a
1248 copy() method.
1249
Andrew MacIntyre92913322006-06-13 15:04:24 +00001250- Patch #1454481: thread stack size is now tunable at runtime for thread
1251 enabled builds on Windows and systems with Posix threads support.
1252
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001253- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1254 (up to the system limit of 32K characters).
1255
1256- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1257 As a result, these functions now raise WindowsError instead of OSError.
1258
Tim Peters7a822da2006-05-25 21:50:17 +00001259- ``time.clock()`` on Win64 should use the high-performance Windows
1260 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1261 Windows platforms).
1262
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001263- Calling Tk_Init twice is refused if the first call failed as that
1264 may deadlock.
1265
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001266- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1267 accept it without potentially using an uninitialized pointer.
1268
1269- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1270 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1271 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001272
Gregory P. Smith372b5832006-06-05 18:48:21 +00001273- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001274 [pybsddb project SF patch number 1466734]
1275
Gregory P. Smith372b5832006-06-05 18:48:21 +00001276- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1277 parameter is supplied. [SF pybsddb bug #1477863]
1278
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001279- bsddb: the __len__ method of a DB object has been fixed to return correct
1280 results. It could previously incorrectly return 0 in some cases.
1281 Fixes SF bug 1493322 (pybsddb bug 1184012).
1282
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001283- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1284 aborts the db transaction safely when a modifier callback fails.
1285 Fixes SF python patch/bug #1408584.
1286
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001287- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001288 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001289 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1290 database calls that would previously deadlock. [SF python bug #775414]
1291
Vinay Sajip28e57612006-07-01 10:45:20 +00001292- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001293
Walter Dörwald4994d952006-06-19 08:07:50 +00001294- Patch #1506645: add Python wrappers for the curses functions
1295 is_term_resized, resize_term and resizeterm.

1299
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001300- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1301 functions.
1302
Martin v. Löwis3798da02006-06-17 18:44:27 +00001303- Patch #812986: Update turtle output even if not tracing.
1304
Vinay Sajip28e57612006-07-01 10:45:20 +00001305- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001306 Tkinter.BaseWidget.
1307
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001308- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1309
Martin v. Löwis337487e2006-06-17 09:15:14 +00001310- Patch #763580: Add name and value arguments to Tkinter variable
1311 classes.
1312
Georg Brandl83cc0d02006-06-14 08:50:03 +00001313- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1314 mime.types file for determining MIME types.
1315
Georg Brandl2605ca82006-06-14 06:08:31 +00001316- Bug #1339007: Shelf objects now don't raise an exception in their
1317 __del__ method when initialization failed.
1318
Martin v. Löwisd8251432006-06-14 05:21:04 +00001319- Patch #1455898: The MBCS codec now supports the incremental mode for
1320 double-byte encodings.
1321
Tim Peters43898b42006-06-14 04:09:25 +00001322- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1323 guarantee that adjacent triples in the return list always describe
1324 non-adjacent blocks. Previously, a pair of matching blocks could end
1325 up being described by multiple adjacent triples that formed a partition
1326 of the matching pair.
1327
Greg Ward0e0c9f42006-06-11 16:24:11 +00001328- Bug #1498146: fix optparse to handle Unicode strings in option help,
1329 description, and epilog.
1330
Greg Wardd1c797e2006-06-11 14:42:41 +00001331- Bug #1366250: minor optparse documentation error.
1332
Greg Ward7f547402006-06-11 00:40:49 +00001333- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1334 clarify docs.
1335
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001336- The wsgiref package has been added to the standard library.
1337
Nick Coghlan676725d2006-06-08 13:54:49 +00001338- The functions update_wrapper() and wraps() have been added to the functools
1339 module. These make it easier to copy relevant metadata from the original
1340 function when writing wrapper functions.
1341
Tim Petersd6a9eef2006-06-05 01:48:21 +00001342- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1343 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001344
Martin v. Löwis3f767792006-06-04 19:36:28 +00001345- Patch #1359618: Speed up charmap encoder by using a trie structure
1346 for lookup.
1347
Tim Petersd609b1a2006-06-02 23:22:51 +00001348- The functions in the ``pprint`` module now sort dictionaries by key
1349 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1350 if and only if its display required more than one line, although that
1351 wasn't documented. The new behavior increases predictability; e.g.,
1352 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1353
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001354- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1355 (thanks for J. J. Lee).
1356
Georg Brandl2b330372006-05-28 20:23:12 +00001357- Patch #1496206: improve urllib2 handling of passwords with respect to
1358 default HTTP and HTTPS ports.
1359
George Yoshidaf3c65de2006-05-28 16:39:09 +00001360- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1361
Bob Ippolito7298f272006-05-23 18:43:47 +00001362- Patch #1281707: speed up gzip.readline.
1363
Georg Brandlb89316f2006-05-17 15:51:16 +00001364- Patch #1180296: Two new functions were added to the locale module:
1365 format_string() to get the effect of "format % items" but locale-aware,
1366 and currency() to format a monetary number with currency sign.
1367
Georg Brandle3a25832006-05-17 14:56:04 +00001368- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1369 and several features added, such as speed and geometry control.
1370
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001371- Patch #1488881: add support for external file objects in bz2 compressed
1372 tarfiles.
1373
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001374- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1375 stdout arguments, making it possible to redirect input and output
1376 for remote debugging.
1377
1378- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1379 a couple of issues, notably handling of long file names using the
1380 GNU LONGNAME extension.
1381
1382- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1383 new flag when ``name`` is already the name of an option flag.
1384
1385- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1386 package.
1387
1388- Patch #1472854: make the rlcompleter.Completer class usable on non-
1389 UNIX platforms.
1390
1391- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1392
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001393- Bug #1472827: correctly escape newlines and tabs in attribute values in
1394 the saxutils.XMLGenerator class.

1426
1427*Release date: 27-APR-2006*
1428
1429Core and builtins
1430-----------------
1431
Thomas Heller1b046642006-04-18 18:51:06 +00001432- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1433 by converting these apis from macros into exported functions again:
1434
1435 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1436 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1437 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1438 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1439 PyRun_String Py_CompileString
1440
Martin v. Löwis45294a92006-04-18 06:24:08 +00001441- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1442
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001443- All uses of PyStructSequence_InitType have been changed to initialize
1444 the type objects only once, even if the interpreter is initialized
1445 multiple times.
1446
Neal Norwitz61546162006-04-14 05:20:28 +00001447- Bug #1454485, array.array('u') could crash the interpreter. This was
1448 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1449 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1450
1451- Py_UNICODE is unsigned. It was always documented as unsigned, but
1452 due to a bug had a signed value in previous versions.
1453
Tim Peters3a5e8b12006-04-11 01:44:07 +00001454- Patch #837242: ``id()`` of any Python object always gives a positive
1455 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1456 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001457 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001458 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001459
Tim Peters3a5e8b12006-04-11 01:44:07 +00001460 def __hash__(self):
1461 return id(self) # WRONG
1462
1463 because a hash result must be a (short) Python int but it was always
1464 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001465 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001466 was always usable as a hash value before this patch. That's no longer
1467 necessarily so.
1468
1469- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001470 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001471 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001472 #1454844)
1473
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001474- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1475 involving generators that have paused outside of any ``try`` or ``with``
1476 blocks. (In 2.5a1, a paused generator that was part of a reference
1477 cycle could not be garbage collected, regardless of whether it was
1478 paused in a ``try`` or ``with`` block.)

1481-----------------
1482
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001483- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1484 is a macro.
1485
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001486- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1487 fails with an error condition.
1488
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001489- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1490
1491- Bug #1117761: bsddb.*open() no longer raises an exception when using
1492 the cachesize parameter.
1493
1494- Bug #1149413: bsddb.*open() no longer raises an exception when using
1495 a temporary db (file=None) with the 'n' flag to truncate on open.

Peter Astrand7d1d4362006-07-14 14:04:45 +00001506- Bug #1223937: subprocess.CalledProcessError reports the exit status
1507 of the process using the returncode attribute, instead of
1508 abusing errno.
1509
Tim Peters711bf302006-04-25 03:31:36 +00001510- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1511 a doctest to be skipped (the code is not run, and the expected output
1512 or exception is ignored).
1513
Nick Coghlanda2268f2006-04-24 04:37:15 +00001514- Fixed contextlib.nested to cope with exceptions being raised and
1515 caught inside exit handlers.
1516
Greg Wardab05edc2006-04-23 03:47:58 +00001517- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1518 hex, octal, or binary; add ``append_const`` action; keep going if
1519 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1520 added ``epilog`` for better help generation).
1521
Tim Peters21fbd572006-04-21 21:18:10 +00001522- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1523 called from a thread spawned as a side effect of importing a module.
1524
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001525- The pydoc module now supports documenting packages contained in
1526 .zip or .egg files.
1527
1528- The pkgutil module now has several new utility functions, such
1529 as ``walk_packages()`` to support working with packages that are either
1530 in the filesystem or zip files.
1531
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001532- The mailbox module can now modify and delete messages from
1533 mailboxes, in addition to simply reading them. Thanks to Gregory
1534 K. Johnson for writing the code, and to the 2005 Google Summer of
1535 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001536
Tim Petersc7605f22006-04-17 21:12:33 +00001537- The ``__del__`` method of class ``local`` in module ``_threading_local``
1538 returned before accomplishing any of its intended cleanup.

Anthony Baxtere29002c2006-04-12 12:07:31 +00001546- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1547 Windows. Bug #1469163.
1548
Phillip J. Eby47032112006-04-11 01:07:43 +00001549- The warnings, linecache, inspect, traceback, site, and doctest modules
1550 were updated to work correctly with modules imported from zipfiles or
1551 via other PEP 302 __loader__ objects.
1552
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001553- Patch #1467770: Reduce usage of subprocess._active to processes which

1559
Skip Montanaro262fb922006-04-21 02:31:07 +00001560- The pstats.Stats class accepts an optional stream keyword argument to
1561 direct output to an alternate file-like object.
1562
Anthony Baxter51bcb682006-04-05 14:51:42 +00001563Build
1564-----
1565
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001566- The Makefile now has a reindent target, which runs reindent.py on
1567 the library.
1568
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001569- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001572
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001573- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1574 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001575 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001576 CXX from --with-cxx-main, see description in README.
1577
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001578- Patch #1429775: Link extension modules with the shared libpython.
1579
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001580- Fixed a libffi build problem on MIPS systems.
1581
Tim Peters8931ff12006-05-13 23:28:20 +00001582- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1583 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1584 and "%zu" for unsigned integers of type ``size_t``.
1585
Anthony Baxter51bcb682006-04-05 14:51:42 +00001586Tests
1587-----
1588
Nick Coghlanda2268f2006-04-24 04:37:15 +00001589- test_contextlib now checks contextlib.nested can cope with exceptions
1590 being raised and caught inside exit handlers.
1591
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001592- test_cmd_line now checks operation of the -m and -c command switches
1593
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001594- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1595 it separately and by hand. It also wasn't cleaning up its changes to
1596 the current Decimal context.
1597
Thomas Woutersabd08882006-04-26 15:53:30 +00001598- regrtest.py now has a -M option to run tests that test the new limits of
1599 containers, on 64-bit architectures. Running these tests is only sensible
1600 on 64-bit machines with more than two gigabytes of memory. The argument
1601 passed is the maximum amount of memory for the tests to use.

1610-------------
1611
Tim Petersb06d28c2006-05-12 01:57:59 +00001612- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1613
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001614- PEP 343: Added Context Types section to the library reference
1615 and attempted to bring other PEP 343 related documentation into
1616 line with the implementation and/or python-dev discussions.
1617
Tim Peters8dc73d22006-04-24 02:03:16 +00001618- Bug #1337990: clarified that ``doctest`` does not support examples
1619 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001622What's New in Python 2.5 alpha 1?
1623=================================
1624
Anthony Baxterebed3f62006-04-03 15:03:44 +00001625*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001626
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001627Core and builtins
1628-----------------
1629
Nick Coghlan43832302006-04-23 17:04:07 +00001630- PEP 338: -m command line switch now delegates to runpy.run_module
1631 allowing it to support modules in packages and zipfiles
1632
Martin v. Löwisc661b882006-04-20 04:54:23 +00001633- On Windows, .DLL is not an accepted file name extension for
1634 extension modules anymore; extensions are only found if they
1635 end in .PYD.
1636
Martin v. Löwisea62d252006-04-03 10:56:49 +00001637- Bug #1421664: sys.stderr.encoding is now set to the same value as
1638 sys.stdout.encoding.
1639
Neal Norwitz92e212f2006-04-03 04:48:37 +00001640- __import__ accepts keyword arguments.
1641
Georg Brandlccadf842006-03-31 18:54:53 +00001642- Patch #1460496: round() now accepts keyword arguments.
1643
Anthony Baxter262c00a2006-03-30 10:53:17 +00001644- Fixed bug #1459029 - unicode reprs were double-escaped.
1645
Hye-Shik Changd478f342006-03-23 12:32:36 +00001646- Patch #1396919: The system scope threads are reenabled on FreeBSD
1647 5.4 and later versions.
1648
Neal Norwitze98ccf62006-03-23 05:39:47 +00001649- Bug #1115379: Compiling a Unicode string with an encoding declaration
1650 now gives a SyntaxError.
1651
Georg Brandlabd1ff82006-03-18 07:59:59 +00001652- Previously, Python code had no easy way to access the contents of a
1653 cell object. Now, a ``cell_contents`` attribute has been added
1654 (closes patch #1170323).
1655
Tim Peterscf79aac2006-03-16 01:14:46 +00001656- Patch #1123430: Python's small-object allocator now returns an arena to
1657 the system ``free()`` when all memory within an arena becomes unused
1658 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1659 freed. Some applications will see a drop in virtual memory size now,
1660 especially long-running applications that, from time to time, temporarily
1661 use a large number of small objects. Note that when Python returns an
1662 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001663 platform C library will in turn return that memory to the operating system.
1664 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001665 appears to be effective at least on Microsoft C and gcc-based systems.
1666 Thanks to Evan Jones for hard work and patience.
1667
Georg Brandl533ff6f2006-03-08 18:09:27 +00001668- Patch #1434038: property() now uses the getter's docstring if there is
1669 no "doc" argument given. This makes it possible to legitimately use
1670 property() as a decorator to produce a read-only property.
1671
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001672- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1673 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1674 of requiring an int or long in slicing and a few other contexts, enabling
1675 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1676
Neal Norwitz995acdf2006-03-07 05:01:00 +00001677- Fixed various bugs reported by Coverity's Prevent tool.
1678
Brett Cannonbf364092006-03-01 04:25:17 +00001679- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1680 new exception base class, BaseException, which has a new message attribute.
1681 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1682 Raising a string exception now raises a DeprecationWarning.
1683
Thomas Woutersfb609f42006-02-28 16:37:25 +00001684- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1685 explicitly relative, using 'from .module import name' to mean 'from the same
1686 package as this module is in. Imports without dots still default to the
1687 old relative-then-absolute, unless 'from __future__ import
1688 absolute_import' is used.
1689
Brett Cannona7446e32006-02-27 23:39:10 +00001690- Properly check if 'warnings' raises an exception (usually when a filter set
1691 to "error" is triggered) when raising a warning for raising string
1692 exceptions.
1693
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001694- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001695 The name was removed from Include/code.h.
1696
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001697- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001698
Guido van Rossum1968ad32006-02-25 22:38:04 +00001699- Patch 1433928:
1700 - The copy module now "copies" function objects (as atomic objects).
1701 - dict.__getitem__ now looks for a __missing__ hook before raising
1702 KeyError.
1703
Tim Peters84ef21c2006-02-28 20:39:06 +00001704- PEP 343: with statement implemented. Needs ``from __future__ import
1705 with_statement``. Use of 'with' as a variable will generate a warning.
1706 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001707 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001708 The following objects have __context__ methods:
1709 - The built-in file type.
1710 - The thread.LockType type.
1711 - The following types defined by the threading module:
1712 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1713 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001714
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001715- Fix the encodings package codec search function to only search
1716 inside its own package. Fixes problem reported in patch #1433198.
1717
1718 Note: Codec packages should implement and register their own
1719 codec search function. PEP 100 has the details.
1720
Tim Peters9ea89d22006-06-04 03:26:02 +00001721- PEP 353: Using ``Py_ssize_t`` as the index type.
1722
1723- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1724 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1725 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1726 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1727 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001728
Neal Norwitzfc76d632006-01-10 06:03:13 +00001729- Patch #1400181, fix unicode string formatting to not use the locale.
1730 This is how string objects work. u'%f' could use , instead of .
1731 for the decimal point. Now both strings and unicode always use periods.
1732
Neal Norwitz671b9e32006-01-09 07:07:12 +00001733- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1734 configure would break checking curses.h.
1735
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001736- Bug #959576: The pwd module is now builtin. This allows Python to be
1737 built on UNIX platforms without $HOME set.
1738
Neal Norwitzc10978f2005-12-19 06:07:16 +00001739- Bug #1072182, fix some potential problems if characters are signed.
1740
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001741- Bug #889500, fix line number on SyntaxWarning for global declarations.
1742
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001743- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1744
Neal Norwitze7214a12005-12-18 05:03:17 +00001745- Support for converting hex strings to floats no longer works.
1746 This was not portable. float('0x3') now raises a ValueError.
1747
Barry Warsaw2a38a862005-12-18 01:27:35 +00001748- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001749 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001750 is now displayed in interactive prompt banner.
1751
Georg Brandlfa166682005-12-17 21:45:17 +00001752- Implementation of PEP 341 - Unification of try/except and try/finally.
1753 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001754 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001755
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001756- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1757 now encodes backslash correctly.
1758
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001759- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1760
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001761- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001762 and long longs.
1763
Neal Norwitz67715f02005-11-09 06:59:35 +00001764- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001765 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001766 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001767
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001768- Replaced most Unicode charmap codecs with new ones using the
1769 new Unicode translate string feature in the builtin charmap
1770 codec; the codecs were created from the mapping tables available
1771 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1772 encodings now include a mapping for the Apple logo)
1773
Tim Peterse3547fd2005-12-16 23:13:57 +00001774- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001775
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001776- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001777
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001778- A new AST parser implementation was completed. The abstract
1779 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001780 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001781
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001782- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001783 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1784
Neal Norwitz708e51a2005-10-03 04:48:15 +00001785- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1786
Neal Norwitz11bd1192005-10-03 00:54:56 +00001787- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1788 Provide a warning when a directory is passed on the command line.
1789
Neal Norwitz40d37812005-10-02 01:48:49 +00001790- Fix segfault with invalid coding.
1791
1792- SF bug #772896: unknown encoding results in MemoryError.
1793
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001794- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001795 supported a __len__() method which evaluated to False when the iterator
1796 was empty.
1797
Guido van Rossum630db602005-09-20 18:49:54 +00001798- On 64-bit platforms, when __len__() returns a value that cannot be
1799 represented as a C int, raise OverflowError.
1800
Skip Montanarof8948ca2005-09-19 03:54:46 +00001801- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001802 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001803
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001804- SF bug #893549: parsing keyword arguments was broken with a few format
1805 codes.
1806
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001807- Changes donated by Elemental Security to make it work on AIX 5.3
1808 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1809 bug #105470: test_pwd fails on 64bit system (Opteron).
1810
Guido van Rossum539c6622005-09-14 17:49:54 +00001811- Changes donated by Elemental Security to make it work on HP-UX 11 on
1812 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1813
Georg Brandl4550b8d2005-08-26 06:43:52 +00001814- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001815 (fixes bug #1119418).
1816
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001817- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1818
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001819- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1820 exceptions that cause a function to exit.
1821
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001822- The implementation of set() and frozenset() was revised to use its
1823 own internal data structure. Memory consumption is reduced by 1/3
1824 and there are modest speed-ups as well. The API is unchanged.
1825
Tim Petersde7990b2005-07-17 23:45:23 +00001826- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1827
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001828- SF bug #1229429: PyObject_CallMethod failed to decrement some
1829 reference counts in some error exit cases.
1830
Tim Petersecc6e6a2005-07-10 22:30:55 +00001831- SF bug #1185883: Python's small-object memory allocator took over
1832 a block managed by the platform C library whenever a realloc specified
1833 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001834 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001835 portable way to copy data from the C-managed block into Python's
1836 small-object space without risking a memory fault. Python's small-object
1837 realloc now leaves such blocks under the control of the platform C
1838 realloc.
1839
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001840- SF bug #1232517: An overflow error was not detected properly when
1841 attempting to convert a large float to an int in os.utime().
1842
Raymond Hettinger3296e692005-06-29 23:29:56 +00001843- SF bug #1224347: hex longs now print with lowercase letters just
1844 like their int counterparts.
1845
Michael W. Hudson188d4362005-06-20 16:52:57 +00001846- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1847 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1848 interpreter states; back out that fix and do a better job (see
1849 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1850 for a longer write-up of the problem).
1851
Michael W. Hudsondf888462005-06-03 14:41:55 +00001852- SF patch #1180995: marshal now uses a binary format by default when
1853 serializing floats.
1854
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001855- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1856 the routines that promise to produce IEEE 754 binary representations
1857 of floats now simply copy bytes around.
1858
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001859- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1860 278.
1861
Brett Cannonc3647ac2005-04-26 03:45:26 +00001862- patch #1109424: int, long, float, complex, and unicode now check for the
1863 proper magic slot for type conversions when subclassed. Previously the
1864 magic slot was ignored during conversion. Semantics now match the way
1865 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001866 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001867 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001868 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001869
Barry Warsawc8d907c2005-04-19 23:43:40 +00001870- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1871 NULL, now raise an AttributeError when attempting to set or delete the
1872 attribute. Previously a TypeError was raised, but this was inconsistent
1873 with the equivalent pure-Python implementation.
1874
Michael W. Hudson774479c2005-04-18 08:46:17 +00001875- It is now safe to call PyGILState_Release() before
1876 PyEval_InitThreads() (note that if there is reason to believe there
1877 are multiple threads around you still must call PyEval_InitThreads()
1878 before using the Python API; this fix is for extension modules that
1879 have no way of knowing if Python is multi-threaded yet).
1880
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001881- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1882 disabled caused a crash.
1883
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001884- Bug #1165306: instancemethod_new allowed the creation of a method
1885 with im_class == im_self == NULL, which caused a crash when called.
1886
Tim Petersecc6e6a2005-07-10 22:30:55 +00001887- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001888 fixes the crash seen in bug #1165761
1889
Raymond Hettinger96229b12005-03-11 06:49:40 +00001890- Added two new builtins, any() and all().
1891
Brett Cannon409d8f22005-03-05 06:47:57 +00001892- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001893 (e.g., ``class C(): pass`` is no longer a syntax error).
1894 Patch #1176012 added support to the 'parser' module and 'compiler' package
1895 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001896
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001897- Patch #1115086: Support PY_LONGLONG in structmember.
1898
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001899- Bug #1155938: new style classes did not check that __init__() was
1900 returning None.
1901
Tim Petersecc6e6a2005-07-10 22:30:55 +00001902- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001903 ('\') with a specific error message.
1904
Martin v. Löwisff232d72005-03-03 09:24:38 +00001905- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1906
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001907- Bug #1124295: the __name__ attribute of file objects was
1908 inadvertently made inaccessible in restricted mode.
1909
Tim Petersecc6e6a2005-07-10 22:30:55 +00001910- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001911 an ferror() call.
1912
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001913- min() and max() now support key= arguments with the same meaning as in
1914 list.sort().
1915
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001916- The peephole optimizer now performs simple constant folding in expressions:
1917 (2+3) --> (5).
1918
Raymond Hettingera422c342005-01-11 03:03:27 +00001919- set and frozenset objects can now be marshalled. SF #1098985.
1920
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001921- Bug #1077106: Poor argument checking could cause memory corruption
1922 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001923
Jeremy Hyltonab630502005-02-04 18:44:06 +00001924- The parser did not complain about future statements in illegal
1925 positions. It once again reports a syntax error if a future
1926 statement occurs after anything other than a doc string.
1927
Neil Schemenauercf52c072005-08-12 17:34:58 +00001928- Change the %s format specifier for str objects so that it returns a
1929 unicode instance if the argument is not an instance of basestring and
1930 calling __str__ on the argument returns a unicode instance.
1931
Tim Petersf4e69282006-02-27 17:15:31 +00001932- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1933 current thread state when the auto-GIL-state machinery knows about
1934 it (since the thread state is being deleted, continuing to remember it
1935 can't help, but can hurt if another thread happens to get created with
1936 the same thread id).
1937
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001938Extension Modules
1939-----------------
1940

Neal Norwitz10be10c2006-03-16 06:50:13 +00001954 util, whatsound, whrandom, zmod
1955
1956- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1957
1958- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001959 is deprecated. The undocumented re.engine variable no longer exists.
1960
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001961- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1962 SS2 (single-shift 2) escape sequences correctly.
1963
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001964- The unicodedata module was updated to the 4.1 version of the Unicode
1965 database. The 3.2 version is still available as unicodedata.db_3_2_0
1966 for applications that require this specific version (such as IDNA).
1967
Neal Norwitzb62c4332006-03-04 18:35:47 +00001968- The timing module is no longer built by default. It was deprecated
1969 in PEP 4 in Python 2.0 or earlier.
1970
Guido van Rossum1968ad32006-02-25 22:38:04 +00001971- Patch 1433928: Added a new type, defaultdict, to the collections module.
1972 This uses the new __missing__ hook behavior added to dict (see above).
1973
Georg Brandldbd83392006-02-20 09:42:33 +00001974- Bug #854823: socketmodule now builds on Sun platforms even when
1975 INET_ADDRSTRLEN is not defined.
1976
Georg Brandlf4f44152006-02-18 22:29:33 +00001977- Patch #1393157: os.startfile() now has an optional argument to specify
1978 a "command verb" to invoke on the file.
1979
Neal Norwitz082b2df2006-02-07 07:04:46 +00001980- Bug #876637, prevent stack corruption when socket descriptor

1982
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00001983- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
1984 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.

1988 than the system default domain.
1989
Martin v. Löwis14694662006-02-03 12:54:16 +00001990- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1991 are reported, the limit on path name lengths is removed, and stat reports
1992 WindowsError now (instead of OSError).
1993
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001994- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

Michael W. Hudson8137bea2005-07-27 20:24:40 +00002068- Patch #1231069: The fcntl.ioctl function now uses the 'I' code for
2069 the request code argument, which results in more C-like behaviour
2070 for large or negative values.
2071
Tim Petersecc6e6a2005-07-10 22:30:55 +00002072- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

2087
Raymond Hettinger984f9bb2005-03-09 16:38:48 +00002088- operator.itemgetter() and operator.attrgetter() now support retrieving

2114
Raymond Hettingerb2594052004-12-05 09:25:51 +00002115- itertools.islice() now accepts None for the start and step arguments.

2117 islice(s.start, s.stop, s.step)
2118
Skip Montanaro0af3ade2005-01-13 04:12:31 +00002119- datetime.datetime() now has a strptime class method which can be used to

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002128- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2129 been renamed to have only a single underscore prefix. This was done to
2130 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002131
Nick Coghlan43832302006-04-23 17:04:07 +00002132- PEP 338: new module runpy defines a run_module function to support
2133 executing modules which provide access to source code or a code object
2134 via the PEP 302 import mechanisms.
2135
Anthony Baxter93f5b932006-04-03 08:05:07 +00002136- The email module's parsedate_tz function now sets the daylight savings
2137 flag to -1 (unknown) since it can't tell from the date whether it should

2144 in attribute values.
2145
Anthony Baxterc51ee692006-04-01 00:57:31 +00002146- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002147 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002148 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002149 module will not be built.
2150
Tim Petersc17976e2006-04-01 00:26:53 +00002151- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2152 aren't officially supported here, and trying to use them will probably
2153 raise an exception some day. But dicts have been allowed, and "mostly
2154 worked", so support for them won't go away without warning.
2155
Georg Brandl338ef7d2006-03-31 18:42:16 +00002156- Bug #1445068: getpass.getpass() can now be given an explicit stream
2157 argument to specify where to write the prompt.
2158
Georg Brandl22ec80b2006-03-31 18:25:44 +00002159- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2166
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002167- Queue.Queue objects now support .task_done() and .join() methods
2168 to make it easier to monitor when daemon threads have completed
2169 processing all enqueued tasks. Patch #1455676.
2170

2174
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002175- email 4.0 package now integrated. This is largely the same as the email 3.0
2176 package that was included in Python 2.3, except that PEP 8 module names are
2177 now used (e.g. mail.message instead of email.Message). The MIME classes
2178 have been moved to a subpackage (e.g. email.mime.text instead of
2179 email.MIMEText). The old names are still supported for now. Several
2180 deprecated Message methods have been removed and lots of bugs have been
2181 fixed. More details can be found in the email package documentation.
2182
Walter Dörwald40108c92006-03-27 08:15:44 +00002183- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2184 (a subclass of tuple) that provides incremental decoders and encoders
2185 (a way to use stateful codecs without the stream API). Python functions
2186 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2187 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2188 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002189
Walter Dörwald067db482006-03-15 22:17:27 +00002190- Patch #1359365: Calling next() on a closed StringIO.String object raises
2191 a ValueError instead of a StopIteration now (like file and cString.String do).
2192 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2193 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002194
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002195- A regrtest option -w was added to re-run failed tests in verbose mode.

2205
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002206- PEP 343: new module contextlib.py defines decorator @contextmanager
2207 and helpful context managers nested() and closing().
2208
Martin v. Löwis415ed932006-02-27 19:56:30 +00002209- The compiler package now supports future imports after the module docstring.

Martin v. Löwis3e865952006-01-24 15:51:21 +00002243 specifications, raises IOErrors when proxies for unsupported protocols
2244 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00002267 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2268 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2269 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2270 Ronald L. Rivest offered this advice for Python:
2271
2272 "The consensus of researchers in this area (at least as
2273 expressed at the NIST Hash Function Workshop 10/31/05),
2274 is that SHA-256 is a good choice for the time being, but
2275 that research should continue, and other alternatives may
2276 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002277
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002278- Added a subset of Fredrik Lundh's ElementTree package. Available

2371 Bug #1224621.
2372
Raymond Hettinger68c04532005-06-10 11:05:19 +00002373- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002374 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002375 the generate_tokens() function now accepts a callable argument that
2376 terminates by raising StopIteration.
2377
Georg Brandl9166e1a2005-06-04 09:20:03 +00002378- Bug #1196315: fix weakref.WeakValueDictionary constructor.

2386 class at all.
2387
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002388- distutils.commands.upload was added to support uploading distribution

2390
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002391- distutils.commands.register now encodes the data as UTF-8 before posting
2392 them to PyPI.
2393
Raymond Hettinger267b8682005-03-27 10:47:39 +00002394- decimal operator and comparison methods now return NotImplemented
2395 instead of raising a TypeError when interacting with other types. This
2396 allows other classes to implement __radd__ style methods and have them
2397 work as expected.
2398
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002399- Bug #1163325: Decimal infinities failed to hash. Attempting to
2400 hash a NaN raised an InvalidOperation instead of a TypeError.
2401
Tim Petersecc6e6a2005-07-10 22:30:55 +00002402- Patch #918101: Add tarfile open mode r|* for auto-detection of the

2436
Guido van Rossumd0641422005-02-03 15:01:24 +00002437- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2438 disables recursive traversal through instance attributes, which can
2439 be exploited in various ways.
2440
Tim Peterse3547fd2005-12-16 23:13:57 +00002441- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002442 flags on the HTTP listening socket.
2443
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002444- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2445 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2446
Fred Drakefbdeaad2006-07-29 16:56:15 +00002447- Patches #893642, #1039083: add allow_none, encoding arguments to
2448 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002449
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002450- Bug #1110478: Revert os.environ.update to do putenv again.
2451
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002452- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2453
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002454- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2455
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002456- Enhancements to the csv module:
2457
2458 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002459 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002460 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002461 + Dialect parameter parsing has been re-implemented to improve error
2462 reporting.
2463 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2464 dictates.
2465 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002466 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002467 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002468 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2469 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002470 + reader now allows \r characters to be quoted (previously it only allowed
2471 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002472 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002473 + Dialect classes passed to the module are no longer instantiated by
2474 the module before being parsed (the former validation scheme required
2475 this, but the mechanism was unreliable).
2476 + The dialect registry now contains instances of the internal
2477 C-coded dialect type, rather than references to python objects.
2478 + the internal c-coded dialect type is now immutable.
2479 + register_dialect now accepts the same keyword dialect specifications
2480 as the reader and writer, allowing the user to register dialects
2481 without first creating a dialect class.
2482 + a configurable limit to the size of parsed fields has been added -
2483 previously, an unmatched quote character could result in the entire
2484 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002485 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002486 the parser field size limit (returning the former limit). The initial
2487 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002488 + A line_num attribute has been added to the reader object, which tracks
2489 the number of lines read from the source iterator. This is not
2490 the same as the number of records returned, as records can span
2491 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002492 + reader and writer objects were not being registered with the cyclic-GC.
2493 This has been fixed.
2494
Brett Cannone6539c42005-01-08 02:43:53 +00002495- _DummyThread objects in the threading module now delete self.__block that is
2496 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2497 lock primitives tend to be limited in number and thus should not be wasted on
2498 a _DummyThread object. Fixes bug #1089632.
2499
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002500- The imghdr module now detects Exif files.
2501
Raymond Hettinger6065d322004-12-20 23:51:53 +00002502- StringIO.truncate() now correctly adjusts the size attribute.
2503 (Bug #951915).
2504
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002505- locale.py now uses an updated locale alias table (built using
2506 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2507 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002508 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002509
Raymond Hettinger3557f422004-12-07 12:02:02 +00002510- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2511
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002512- the pickle module no longer accepts the deprecated None option in the
2513 args tuple returned by __reduce__().
2514
Brett Cannon84667c02004-12-07 03:25:18 +00002515- optparse now optionally imports gettext. This allows its use in setup.py.
2516
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002517- the pickle module no longer uses the deprecated bin parameter.
2518
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002519- the shelve module no longer uses the deprecated binary parameter.
2520
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002521- the pstats module no longer uses the deprecated ignore() method.
2522
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002523- the filecmp module no longer uses the deprecated use_statcache argument.
2524
Raymond Hettinger664347b2004-12-04 21:21:53 +00002525- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2526 extended or overridden by subclasses. Formerly, the subclassed method would
2527 be ignored by the rest of the module. (Bug #1078905).
2528
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002529- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002530 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002531
Walter Dörwald36733692004-12-22 12:50:50 +00002532- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2533 once when a size argument is given. This prevents a buffer overflow in the
2534 tokenizer with very long source lines.
2535
Barry Warsaw538561e2006-01-01 21:48:54 +00002536- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2537 immediately after creating the object, without any intervening
2538 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002539
Skip Montanaro05885812005-01-16 20:48:27 +00002540- The reconvert.quote function can now emit triple-quoted strings. The
2541 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002542
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002543- ``UserString.MutableString`` now supports negative indices in
2544 ``__setitem__`` and ``__delitem__``
2545
Greg Ward40407942005-03-05 02:53:17 +00002546- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2547 correctly.
2548
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002549- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2550 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2551 character even if the user has passed a size parameter to get a proper
2552 line ending. Remove the special handling of a "\r\n" that has been split
2553 between two lines.
2554
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002555- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2556 about illegal code points. The codec now supports PEP 293 style error
2557 handlers.
2558
Walter Dörwald78a78b02005-09-01 12:04:29 +00002559- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002560 from the input stream, so that the output is a byte string in the correct
2561 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002562
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002563- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2564 considering it exactly like a '*'.

Walter Dörwald007f8df2005-10-09 19:42:27 +00002566- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2567 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002568
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002569- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2570
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002571- Patch #1413711: Certain patterns of differences were making difflib
2572 touch the recursion limit.
2573
Walter Dörwald58917a62006-03-31 15:26:22 +00002574- Bug #947906: An object oriented interface has been added to the calendar
2575 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002576 called as a script (e.g. via ``python -mcalendar``). Localized month and
2577 weekday names can be ouput (even if an exotic encoding is used) using
2578 special classes that use unicode.

2582
Neal Norwitz602d3392006-03-31 08:21:40 +00002583- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2584 by using -mieee gcc option.
2585

2587
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002588- Build support for Win64-AMD64 was added.
2589
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002590- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2591
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002592- Patch #881820: look for openpty and forkpty also in libbsd.
2593
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002594- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2595 The zlib module is now builtin on Windows.
2596
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002597- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2598
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002599- Bug #1189330: configure did not correctly determine the necessary
2600 value of LINKCC if python was built with GCC 4.0.
2601
Trent Mick8321b422005-07-26 02:29:21 +00002602- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2603 vulnerability in zlib 1.2.1 and 1.2.2.
2604
Brett Cannon08cd5982005-04-24 22:26:38 +00002605- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2606 flags that change binary compatibility. Changes were also made to
2607 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002608 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002609
Bob Ippolitoed233462005-03-29 13:47:59 +00002610- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2611 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2612 no longer exists). This configure patch makes things right.
2613
Martin v. Löwise2713be2005-03-08 15:03:08 +00002614- Bug #1158607: Build with --disable-unicode again.
2615
Brett Cannon46d96232005-02-16 00:07:19 +00002616- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2617 defined. Discovered as a result of not being able to build on OS X.
2618
Brett Cannon516592f2004-12-07 00:42:59 +00002619- setup.py now uses the directories specified in LDFLAGS using the -L option
2620 and in CPPFLAGS using the -I option for adding library and include
2621 directories, respectively, for compiling extension modules against. This has
2622 led to the core being compiled using the values in CPPFLAGS. It also removes
2623 the need for the special-casing of both DarwinPorts and Fink for darwin since
2624 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2625 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2626 Fink, ``-I/opt/local/include`` for DarwinPorts).
2627
Brett Cannon43802422005-02-10 20:48:03 +00002628- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2629 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2630 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2631 Closes bug #1096244. Thanks Gregory Bond.

2634-----
2635
Tim Petersc9d78aa2006-03-26 23:27:58 +00002636- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2637 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2638 is obtained via the ``PyObject_`` family, it must be released via the
2639 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2640 always been officially true, but when Python's small-object allocator was
2641 introduced, an attempt was made to cater to a few extension modules
2642 discovered at the time that obtained memory via ``PyObject_New`` but
2643 released it via ``PyMem_DEL``. It's years later, and if such code still
2644 exists it will fail now (probably with segfaults, but calling wrong
2645 low-level memory management functions can yield many symptoms).
2646
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002647- Added a C API for set and frozenset objects.
2648
Raymond Hettinger66517482004-12-03 11:45:13 +00002649- Removed PyRange_New().
2650
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002651- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2652 mapping argument now. This string is used as a mapping table. Byte values
2653 greater than the length of the string and 0xFFFE are treated as undefined
2654 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002661
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002662- Patch #1276356: New resource "urlfetch" is implemented. This enables
2663 even impatient people to run tests that require remote files.
