14
Georg Brandlaa2321b2007-03-07 00:40:28 +000015- Patch #703779: unset __file__ in __main__ after running a file. This
16 makes the filenames the warning module prints much more sensible when
17 a PYTHONSTARTUP file is used.
18
Georg Brandl49aafc92007-03-07 00:34:46 +000019- Variant of patch #697613: don't exit the interpreter on a SystemExit
20 exception if the -i command line option or PYTHONINSPECT environment
21 variable is given, but break into the interactive interpreter just like
22 on other exceptions or normal program exit.
23
Georg Brandl00cd8182007-03-06 18:41:12 +000024- Patch #1638879: don't accept strings with embedded NUL bytes in long().

27
Georg Brandl0fca97a2007-03-05 22:28:08 +000028- Patch #1674228: when assigning a slice (old-style), check for the
29 sq_ass_slice instead of the sq_slice slot.
30
Neal Norwitz88516a62007-02-26 22:41:45 +000031- When printing an unraisable error, don't print exceptions. before the name.
32 This duplicates the behavior whening normally printing exceptions.
33

35
Brett Cannon129bd522007-01-30 21:34:36 +000036- PEP 352: Raising a string exception now triggers a TypeError. Attempting to
37 catch a string exception raises DeprecationWarning.
38
Brett Cannonf5bee302007-01-23 23:21:22 +000039- Bug #1377858: Fix the segfaulting of the interpreter when an object created
40 a weakref on itself during a __del__ call for new-style classes (classic
41 classes still have the bug).
42
Martin v. Löwis6c5c5022007-01-23 21:11:47 +000043- Bug #1579370: Make PyTraceBack_Here use the current thread, not the

68 the tuple isn't used as the "exception arguments tuple".
69
Neal Norwitz21997af2006-10-28 21:19:07 +000070- Bug #1565514, SystemError not raised on too many nested blocks.

77
Neal Norwitzcbeb6872006-10-14 21:33:38 +000078- Update the peephole optimizer to remove more dead code (jumps after returns)

88
89- Fix some leftovers from the conversion from int to Py_ssize_t
90 (relevant to strings and sequences of more than 2**31 items).
91
92- A number of places, including integer negation and absolute value,
93 were fixed to not rely on undefined behaviour of the C compiler
94 anymore.
Martin v. Löwis820d6ac2006-10-04 05:47:34 +000095
Georg Brandl3267d282006-09-30 09:03:42 +000096- Bug #1566800: make sure that EnvironmentError can be called with any

106
Neal Norwitz3a230172006-09-22 08:18:10 +0000107- Bug #1557232: fix seg fault with def f((((x)))) and def f(((x),)).

112
Brett Cannon9adeab72006-09-20 18:34:28 +0000113- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
114 allows calling unicode() on exceptions classes directly to succeed.
115
Georg Brandlec6c2df2006-09-11 09:38:35 +0000116- Make _PyGILState_NoteThreadState() static, it was not used anywhere
117 outside of pystate.c and should not be necessary.

125
Tim Petersc10c9d02006-09-05 02:18:09 +0000126- Overflow checking code in integer division ran afoul of new gcc
127 optimizations. Changed to be more standard-conforming.

134 head is the original string if sep was not found.
135
Neal Norwitzdac090d2006-09-05 03:53:08 +0000136- Bug #1520864: unpacking singleton tuples in list comprehensions and
137 generator expressions (x for x, in ... ) works again. Fixing this problem
138 required changing the .pyc magic number. This means that .pyc files
139 generated before 2.5c2 will be regenerated.
140
Neal Norwitzca460d92006-09-06 06:28:06 +0000141- with and as are now keywords.

Jeremy Hyltoncca75402007-02-27 18:33:31 +0000145- Add new requirements for metaclasses. 1) If type or a subclass of type
146 occurs in __bases__, it must occur before any non-type bases, e.g.
147 before regular classes. 2) If you assign to __bases__, you may not
148 change the metaclass. Many more illegal assignments to __bases__
149 are now checked and raise TypeErrors. This changed fixed at least
150 one known crash.

625Core and builtins
626-----------------
627
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000628- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000629 compared equal or unequal to a string and a UnicodeDecodeError
630 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000631
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000632 Instead, the equal (==) and unequal (!=) comparison operators will
633 now issue a UnicodeWarning and interpret the two objects as
634 unequal. The UnicodeWarning can be filtered as desired using
635 the warning framework, e.g. silenced completely, turned into an
636 exception, logged, etc.
637
638 Note that compare operators other than equal and unequal will still
639 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000640
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000641- Fix segfault when doing string formatting on subclasses of long.
642
643- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
644 with new-style classes.
645
646- Fix bug related to __len__ functions returning negative values with
647 classic classes.
648
649- Patch #1538606, Fix __index__() clipping. There were some problems
650 discovered with the API and how integers that didn't fit into Py_ssize_t
651 were handled. This patch attempts to provide enough alternatives
652 to effectively use __index__.
653
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000654- Bug #1536021: __hash__ may now return long int; the final hash
655 value is obtained by invoking hash on the long int.
656
Thomas Hellerab1049c2006-08-08 17:37:00 +0000657- Bug #1536786: buffer comparison could emit a RuntimeWarning.
658
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000659- Bug #1535165: fixed a segfault in input() and raw_input() when
660 sys.stdin is closed.
661
Thomas Heller74d36f02006-08-04 18:17:40 +0000662- On Windows, the PyErr_Warn function is now exported from
663 the Python dll again.
664
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000665- Bug #1191458: tracing over for loops now produces a line event
666 on each iteration. Fixing this problem required changing the .pyc
667 magic number. This means that .pyc files generated before 2.5c1
668 will be regenerated.
669
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000670- Bug #1333982: string/number constants were inappropriately stored
671 in the byte code and co_consts even if they were not used, ie
672 immediately popped off the stack.
673
Georg Brandle9462c72006-08-04 18:03:37 +0000674- Fixed a reference-counting problem in property().
675
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000676
677Library
678-------
679
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000680- Fix a bug in the ``compiler`` package that caused invalid code to be
681 generated for generator expressions.
682
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000683- The distutils version has been changed to 2.5.0. The change to
684 keep it programmatically in sync with the Python version running
685 the code (introduced in 2.5b3) has been reverted. It will continue
686 to be maintained manually as static string literal.
687
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000688- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000689 and this cannot be converted to the required C type, an exception is
690 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000691 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000692
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000693- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000694 an exception.
695
Tim Petersc10c9d02006-09-05 02:18:09 +0000696- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000697 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000698 workarounds for clocks with low resolution, to stop the code yielding
699 duplicate UUIDs.
700
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000701- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
702 before raising SystemExit, allowing IDLE to honor quit() and exit().
703
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000704- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
705
Georg Brandl7a1af772006-08-14 21:55:28 +0000706- Patch #1536071: trace.py should now find the full module name of a
707 file correctly even on Windows.
708
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000709- logging's atexit hook now runs even if the rest of the module has
710 already been cleaned up.
711
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000712- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000713
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000714- Bug #1531405, format_exception no longer raises an exception if
715 str(exception) raised an exception.
716
Neil Schemenauer06ded092006-08-04 16:20:30 +0000717- Fix a bug in the ``compiler`` package that caused invalid code to be
718 generated for nested functions.
719
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000720

Neal Norwitzbf8c1952006-08-15 04:14:57 +0000724- Patch #1511317: don't crash on invalid hostname (alias) info.
725
Georg Brandl3335a7a2006-08-14 21:42:55 +0000726- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
727 raises the correct exceptions.
728
Thomas Heller1ce433e2006-08-14 16:20:04 +0000729- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
730 '-no-stack-protector' compiler flag for OpenBSD has been removed.
731
Thomas Heller86720042006-08-14 11:17:48 +0000732- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
733 uses the _as_parameter_ attribute when objects are passed to foreign
734 function calls. The ctypes version number was changed to 1.0.1.
735
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000736- Bug #1530559, struct.pack raises TypeError where it used to convert.
737 Passing float arguments to struct.pack when integers are expected
738 now triggers a DeprecationWarning.
739
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000740

762-----
763
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +0000764- Bug #1535502, build _hashlib on Windows, and use masm assembler
765 code in OpenSSL.
766
Thomas Hellerdb7b4432006-08-04 19:49:31 +0000767- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

Tim Peters4643c2f2006-08-10 22:45:34 +0000772C API
773-----
774
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000775- New API for Unicode rich comparisons: PyUnicode_RichCompare()
776
Tim Peters4643c2f2006-08-10 22:45:34 +0000777- Bug #1069160. Internal correctness changes were made to
778 ``PyThreadState_SetAsyncExc()``. A test case was added, and
779 the documentation was changed to state that the return value
780 is always 1 (normal) or 0 (if the specified thread wasn't found).

788Core and builtins
789-----------------
790
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000791- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000792 returned a long (see PEP 353).
793
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000794- Bug #1515471: string.replace() accepts character buffers again.
795
Neal Norwitz07aadb12006-07-30 06:55:48 +0000796- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
797 This provides the proper warning for struct.pack().
798 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
799
Neal Norwitz0d62a062006-07-30 06:53:31 +0000800- Patch #1531113: Fix augmented assignment with yield expressions.
801 Also fix a SystemError when trying to assign to yield expressions.
802
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000803- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
804 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
805 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
806 excessive filesystem operations during imports.
807
Tim Petersbc24eee2006-07-27 01:14:53 +0000808- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
809 operations on signed longs that are formally undefined by C.
810 Unfortunately, at least one compiler now cares about that, so complicated
811 the code to make that compiler happy again.
812
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000813- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
814
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000815- Patch #1232023: Stop including current directory in search
816 path on Windows.
817
Neal Norwitze1fdb322006-07-21 05:32:28 +0000818- Fix some potential crashes found with failmalloc.
819
Neal Norwitze7563102006-07-17 01:00:16 +0000820- Fix warnings reported by Klocwork's static analysis tool.
821
Neal Norwitz84be93b2006-07-16 01:50:38 +0000822- Bug #1512814, Fix incorrect lineno's when code within a function
823 had more than 255 blank lines.
824
Georg Brandl9dceedb2006-07-12 15:31:17 +0000825- Patch #1521179: Python now accepts the standard options ``--help`` and
826 ``--version`` as well as ``/?`` on Windows.
827
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000828- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000829 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000830 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000831
Tim Peters112aad32006-07-19 00:03:19 +0000832- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000833 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000834 new ``sys._current_frames()`` returns a dictionary with one entry,
835 mapping the faux "thread id" 0 to the current frame.
836
Ronald Oussoren3075e162006-07-25 20:28:55 +0000837- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000838

Neal Norwitza1f10902006-07-12 07:28:29 +0000840Library
841-------
842
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000843- Correction of patch #1455898: In the mbcs decoder, set final=False
844 for stream decoder, but final=True for the decode function.
845
Georg Brandl07fec3a2006-08-01 18:49:24 +0000846- os.urandom no longer masks unrelated exceptions like SystemExit or
847 KeyboardInterrupt.
848
Tim Peters4643c2f2006-08-10 22:45:34 +0000849- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000850 shutil.copytree on Windows
851
Georg Brandle34ac7c2006-07-30 11:07:23 +0000852- Bug #1002398: The documentation for os.path.sameopenfile now correctly
853 refers to file descriptors, not file objects.
854
Tim Petersc10c9d02006-09-05 02:18:09 +0000855- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000856 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000857 #1513611, and probably others.
858
Georg Brandledd9b0d2006-07-29 09:33:26 +0000859- Bug #1441397: The compiler module now recognizes module and function
860 docstrings correctly as it did in Python 2.4.
861
Tim Peters6f681472006-07-27 23:44:37 +0000862- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
863 lost that tests are sorted by name before being run. This rarely
864 matters for well-written tests, but can create baffling symptoms if
865 side effects from one test to the next affect outcomes. ``DocTestFinder``
866 has been changed to sort the list of tests it returns.
867
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000868- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000869 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000870
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000871- Bug #978833: Really close underlying socket in _socketobject.close.
872
Georg Brandl8c036cc2006-08-20 13:15:39 +0000873- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
874 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000875
Georg Brandlcf0c1722006-07-26 07:23:32 +0000876- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
877 to recursive calls and call it with the failing package name.
878
Martin v. Löwis0b483032006-07-25 09:53:12 +0000879- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
880
Georg Brandlc13c34c2006-07-24 14:09:56 +0000881- Patch #1515343: Fix printing of deprecated string exceptions with a
882 value in the traceback module.
883
Greg Ward48fae7a2006-07-23 16:05:51 +0000884- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
885
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000886- Patch #1524429: Use repr() instead of backticks in Tkinter again.
887
Brett Cannoncaebe222006-07-18 04:41:36 +0000888- Bug #1520914: Change time.strftime() to accept a zero for any position in its
889 argument tuple. For arguments where zero is illegal, the value is forced to
890 the minimum value that is correct. This is to support an undocumented but
891 common way people used to fill in inconsequential information in the time
892 tuple pre-2.4.
893
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000894- Patch #1220874: Update the binhex module for Mach-O.
895
Barry Warsawb110bad2006-07-21 14:51:07 +0000896- The email package has improved RFC 2231 support, specifically for
897 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
898 (name*0=<blah>) parameter continuations. This may change the types of
899 values returned from email.message.Message.get_param() and friends.
900 Specifically in some cases where non-encoded continuations were used,
901 get_param() used to return a 3-tuple of (None, None, string) whereas now it
902 will just return the string (since non-encoded continuations don't have
903 charset and language parts).
904
905 Also, whereas % values were decoded in all parameter continuations, they are
906 now only decoded in encoded parameter parts.
907
Ronald Oussoren3075e162006-07-25 20:28:55 +0000908- Bug #1517990: IDLE keybindings on MacOS X now work correctly
909
910- Bug #1517996: IDLE now longer shows the default Tk menu when a
911 path browser, class browser or debugger is the frontmost window on MacOS X
912
Barry Warsaw00decd72006-07-27 23:43:15 +0000913- Patch #1520294: Support for getset and member descriptors in types.py,
914 inspect.py, and pydoc.py. Specifically, this allows for querying the type
915 of an object against these built-in types and more importantly, for getting
916 their docstrings printed in the interactive interpreter's help() function.

921
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000922- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
923 a socket operation on a socket with a timeout, the exception will be
924 caught correctly. Previously, the exception was not caught.
925
Thomas Heller1393d6a2006-07-28 21:43:20 +0000926- Patch #1529514: The _ctypes extension is now compiled on more
927 openbsd target platforms.
928
Tim Peters9cab5932006-07-28 00:30:00 +0000929- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
930 a memory leak, affecting pickles and deep copies.
931
Tim Petersbc24eee2006-07-27 01:14:53 +0000932- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

936
Thomas Hellerce049a02006-07-14 17:51:14 +0000937- Patch #1521817: Index range checking on ctypes arrays containing
938 exactly one element enabled again. This allows iterating over these
939 arrays, without the need to check the array size before.
940
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000941- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000942 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000943 /dev/null in certain cases; this is now fixed.
944
Thomas Heller47d7a062006-07-12 08:43:47 +0000945- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
946 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000947
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000948- Because of a misspelled preprocessor symbol, ctypes was always
949 compiled without thread support; this is now fixed.
950
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000951- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
952 methods now allow their database parameter to be None as the
953 sleepycat API allows.
954
Matt Flemingec926502006-07-28 11:27:27 +0000955- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
956 bluetooth API compared with Linux and FreeBSD.
957
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000958Tests
959-----
960
961- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
962 how long the test file should take to play. Now accepts taking 2.93 secs
963 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
964
Georg Brandl4793aa32006-07-28 18:31:39 +0000965- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
966 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
967 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +0000968
Martin v. Löwis0907f4d2006-07-30 14:09:47 +0000969Build

971
972- Bug #1439538: Drop usage of test -e in configure as it is not portable.
973
Ronald Oussoren26cad082006-08-01 21:00:57 +0000974Mac
975---
976
977- PythonLauncher now works correctly when the path to the script contains
978 characters that are treated specially by the shell (such as quotes).
979
980- Bug #1527397: PythonLauncher now launches scripts with the working directory
981 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000982 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000983 expect.

991Core and builtins
992-----------------
993
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000994- Bug #1441486: The literal representation of -(sys.maxint - 1)
995 again evaluates to a int object, not a long.
996
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000997- Bug #1501934: The scope of global variables that are locally assigned
998 using augmented assignment is now correctly determined.
999
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001000- Bug #927248: Recursive method-wrapper objects can now safely
1001 be released.
1002
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001003- Bug #1417699: Reject locale-specific decimal point in float()
1004 and atof().
1005
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001006- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1007 omit a default "error" argument for NULL pointer. This allows
1008 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001009
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001010- Bug #1519018: 'as' is now validated properly in import statements.
1011
Neal Norwitz28746ab2006-07-09 22:14:42 +00001012- On 64 bit systems, int literals that use less than 64 bits are
1013 now ints rather than longs.
1014
Neal Norwitzed657552006-07-10 00:04:44 +00001015- Bug #1512814, Fix incorrect lineno's when code at module scope
1016 started after line 256.
1017
Tim Peters32a83612006-07-10 21:08:24 +00001018- New function ``sys._current_frames()`` returns a dict mapping thread
1019 id to topmost thread stack frame. This is for expert use, and is
1020 especially useful for debugging application deadlocks. The functionality
1021 was previously available in Fazal Majid's ``threadframe`` extension
1022 module, but it wasn't possible to do this in a wholly threadsafe way from
1023 an extension.

1040
Thomas Woutersadd19112006-07-05 11:03:49 +00001041- string.Template() now correctly handles tuple-values. Previously,
1042 multi-value tuples would raise an exception and single-value tuples would
1043 be treated as the value they contain, instead.

1052 degrees and radians.
1053
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001054- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001055 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001056

1059
Martin v. Löwis7596e832006-07-01 15:33:37 +00001060- Bug #1513223: .close() of a _socketobj now releases the underlying
1061 socket again, which then gets closed as it becomes unreferenced.

1064 attribute values.
1065
1066- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1067 sgmllib ('[' and ']' were not accepted).
1068
Georg Brandl1be63af2006-06-28 20:23:25 +00001069- Fix a bug in the turtle module's end_fill function.
1070
Brett Cannon53ab5b72006-06-22 16:49:14 +00001071- Bug #1510580: The 'warnings' module improperly required that a Warning
1072 category be either a types.ClassType and a subclass of Warning. The proper
1073 check is just that it is a subclass with Warning as the documentation states.
1074
Georg Brandlad29e632006-06-21 17:45:17 +00001075- The compiler module now correctly compiles the new try-except-finally
1076 statement (bug #1509132).
1077
Neal Norwitz60373cd2006-06-22 06:30:50 +00001078- The wsgiref package is now installed properly on Unix.
1079

1081 shutdown when fileConfig() was called multiple times.
1082
Gerhard Häring762fbd32006-07-02 17:48:30 +00001083- The sqlite3 module did cut off data from the SQLite database at the first
1084 null character before sending it to a custom converter. This has been fixed
1085 now.
1086
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001087Extension Modules
1088-----------------
1089
Tim Peters112aad32006-07-19 00:03:19 +00001090- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1091 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1092 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001093
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001094- Assigning None to pointer type fields in ctypes structures possible
1095 overwrote the wrong fields, this is fixed now.
1096
1097- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1098 on non-Windows platforms.
1099
1100- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1101 integer or long, without range checking.
1102
1103- Patch #1517790: It is now possible to use custom objects in the ctypes
1104 foreign function argtypes sequence as long as they provide a from_param
1105 method, no longer is it required that the object is a ctypes type.
1106
1107- The '_ctypes' extension module now works when Python is configured
1108 with the --without-threads option.
1109
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001110- Bug #1513646: os.access on Windows now correctly determines write
1111 access, again.
1112
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001113- Bug #1512695: cPickle.loads could crash if it was interrupted with

1125
Tim Peters32a83612006-07-10 21:08:24 +00001126- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001127 Previously, the slight difference could cause compilation errors of the
1128 'zlib' module on systems with more than one version of zlib.
1129
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001130- The MSI compileall step was fixed to also support a TARGETDIR
1131 with spaces in it.

1146-------------
1147
Nick Coghlan2d792252006-07-06 13:47:18 +00001148- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1149 documentation for the warnings module.
1150
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001151- Patch #1509163: MS Toolkit Compiler no longer available.

1162-----------------
1163
Georg Brandla56b9152006-06-19 06:35:54 +00001164- Patch #1507676: Error messages returned by invalid abstract object operations
1165 (such as iterating over an integer) have been improved and now include the
1166 type of the offending object to help with debugging.
1167
Brett Cannonea3912b2006-06-13 21:46:41 +00001168- Bug #992017: A classic class that defined a __coerce__() method that returned
1169 its arguments swapped would infinitely recurse and segfault the interpreter.
1170
Neal Norwitz909eb122006-06-12 02:13:21 +00001171- Fix the socket tests so they can be run concurrently.
1172
Neal Norwitzb9845e72006-06-12 02:11:18 +00001173- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001174 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001175
Brett Cannon22565aa2006-06-09 22:31:23 +00001176- Bug #532646: object.__call__() will continue looking for the __call__
1177 attribute on objects until one without one is found. This leads to recursion
1178 when you take a class and set its __call__ attribute to an instance of the
1179 class. Originally fixed for classic classes, but this fix is for new-style.
1180 Removes the infinite_rec_3 crasher.
1181
Georg Brandl24250812006-06-09 18:45:48 +00001182- The string and unicode methods startswith() and endswith() now accept
1183 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1184
Brett Cannonde3b0522006-06-08 17:00:45 +00001185- Buffer objects, at the C level, never used the char buffer
1186 implementation even when the char buffer for the wrapped object was
1187 explicitly requested (originally returned the read or write buffer).
1188 Now a TypeError is raised if the char buffer is not present but is
1189 requested.
1190
Georg Brandlddbaa662006-06-04 21:56:52 +00001191- Patch #1346214: Statements like "if 0: suite" are now again optimized
1192 away like they were in Python 2.4.
1193
Georg Brandlb7c8f542006-05-27 12:30:25 +00001194- Builtin exceptions are now full-blown new-style classes instead of
1195 instances pretending to be classes, which speeds up exception handling
1196 by about 80% in comparison to 2.5a2.
1197
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001198- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1199 Unicode 4.1.
1200
Georg Brandlf4ef1162006-05-26 18:03:31 +00001201- Patch #921466: sys.path_importer_cache is now used to cache valid and
1202 invalid file paths for the built-in import machinery which leads to
1203 fewer open calls on startup.
1204
Tim Peters696cf432006-05-24 21:10:40 +00001205- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1206 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1207 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1208 the number of input digits (it was and remains linear-time for bases
1209 2, 4, 8, 16 and 32).
1210
Tim Petersb713ec22006-05-23 18:45:30 +00001211- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1212 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1213 an integer close to ``sys.maxint``. This was repaired by patch
1214 #1335972, which also gives a nice speedup.
1215
Richard Jonescebbefc2006-05-23 18:28:17 +00001216- Patch #1337051: reduced size of frame objects.
1217
1218- PyErr_NewException now accepts a tuple of base classes as its
1219 "base" parameter.
1220
Richard Jones7c88dcc2006-05-23 10:37:38 +00001221- Patch #876206: function call speedup by retaining allocated frame
1222 objects.
1223
Georg Brandl7b90e162006-05-18 07:01:27 +00001224- Bug #1462152: file() now checks more thoroughly for invalid mode
1225 strings and removes a possible "U" before passing the mode to the
1226 C library function.
1227
Neal Norwitz1004a532006-05-15 07:17:23 +00001228- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1229
Neal Norwitz373f0a72006-05-15 07:04:36 +00001230- Bug #1487966: Fix SystemError with conditional expression in assignment
1231
Martin v. Löwis879768d2006-05-11 13:28:43 +00001232- WindowsError now has two error code attributes: errno, which carries
1233 the error values from errno.h, and winerror, which carries the error
1234 values from winerror.h. Previous versions put the winerror.h values
1235 (from GetLastError()) into the errno attribute.
1236
Martin v. Löwis77736712006-05-04 05:51:03 +00001237- Patch #1475845: Raise IndentationError for unexpected indent.
1238
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001239- Patch #1479181: split open() and file() from being aliases for each other.
1240
Tim Peters44bd9862006-06-01 13:49:23 +00001241- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1242 methods were always silently ignored by dictionaries when comparing keys.
1243 They are now passed through (except when using the C API function
1244 ``PyDict_GetItem()``, whose semantics did not change).
1245
1246- Bug #1456209: In some obscure cases it was possible for a class with a
1247 custom ``__eq__()`` method to confuse dict internals when class instances
1248 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1249 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001251Extension Modules
1252-----------------
1253
Trent Mick960a3f82006-06-28 20:30:41 +00001254- Bug #1295808: expat symbols should be namespaced in pyexpat
1255
1256- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1257
Brett Cannon6ee7d012006-06-08 16:23:04 +00001258- Change binascii.hexlify to accept a read-only buffer instead of only a char
1259 buffer and actually follow its documentation.
1260
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001261- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1262
Nick Coghlanc649ec52006-05-29 12:43:05 +00001263- Patch #1478788 (modified version): The functional extension module has
1264 been renamed to _functools and a functools Python wrapper module added.
1265 This provides a home for additional function related utilities that are
1266 not specifically about functional programming. See PEP 309.
1267
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001268- Patch #1493701: performance enhancements for struct module.
1269
Georg Brandl378d5922006-05-17 14:26:50 +00001270- Patch #1490224: time.altzone is now set correctly on Cygwin.
1271
Georg Brandl8d3342b2006-05-16 07:38:27 +00001272- Patch #1435422: zlib's compress and decompress objects now have a
1273 copy() method.
1274
Andrew MacIntyre92913322006-06-13 15:04:24 +00001275- Patch #1454481: thread stack size is now tunable at runtime for thread
1276 enabled builds on Windows and systems with Posix threads support.
1277
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001278- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1279 (up to the system limit of 32K characters).
1280
1281- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1282 As a result, these functions now raise WindowsError instead of OSError.
1283
Tim Peters7a822da2006-05-25 21:50:17 +00001284- ``time.clock()`` on Win64 should use the high-performance Windows
1285 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1286 Windows platforms).
1287
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001288- Calling Tk_Init twice is refused if the first call failed as that
1289 may deadlock.
1290
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001291- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1292 accept it without potentially using an uninitialized pointer.
1293
1294- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1295 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1296 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001297
Gregory P. Smith372b5832006-06-05 18:48:21 +00001298- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001299 [pybsddb project SF patch number 1466734]
1300
Gregory P. Smith372b5832006-06-05 18:48:21 +00001301- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1302 parameter is supplied. [SF pybsddb bug #1477863]
1303
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001304- bsddb: the __len__ method of a DB object has been fixed to return correct
1305 results. It could previously incorrectly return 0 in some cases.
1306 Fixes SF bug 1493322 (pybsddb bug 1184012).
1307
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001308- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1309 aborts the db transaction safely when a modifier callback fails.
1310 Fixes SF python patch/bug #1408584.
1311
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001312- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001313 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001314 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1315 database calls that would previously deadlock. [SF python bug #775414]
1316
Vinay Sajip28e57612006-07-01 10:45:20 +00001317- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001318
Walter Dörwald4994d952006-06-19 08:07:50 +00001319- Patch #1506645: add Python wrappers for the curses functions
1320 is_term_resized, resize_term and resizeterm.

1324
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001325- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1326 functions.
1327
Martin v. Löwis3798da02006-06-17 18:44:27 +00001328- Patch #812986: Update turtle output even if not tracing.
1329
Vinay Sajip28e57612006-07-01 10:45:20 +00001330- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001331 Tkinter.BaseWidget.
1332
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001333- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1334
Martin v. Löwis337487e2006-06-17 09:15:14 +00001335- Patch #763580: Add name and value arguments to Tkinter variable
1336 classes.
1337
Georg Brandl83cc0d02006-06-14 08:50:03 +00001338- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1339 mime.types file for determining MIME types.
1340
Georg Brandl2605ca82006-06-14 06:08:31 +00001341- Bug #1339007: Shelf objects now don't raise an exception in their
1342 __del__ method when initialization failed.
1343
Martin v. Löwisd8251432006-06-14 05:21:04 +00001344- Patch #1455898: The MBCS codec now supports the incremental mode for
1345 double-byte encodings.
1346
Tim Peters43898b42006-06-14 04:09:25 +00001347- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1348 guarantee that adjacent triples in the return list always describe
1349 non-adjacent blocks. Previously, a pair of matching blocks could end
1350 up being described by multiple adjacent triples that formed a partition
1351 of the matching pair.
1352
Greg Ward0e0c9f42006-06-11 16:24:11 +00001353- Bug #1498146: fix optparse to handle Unicode strings in option help,
1354 description, and epilog.
1355
Greg Wardd1c797e2006-06-11 14:42:41 +00001356- Bug #1366250: minor optparse documentation error.
1357
Greg Ward7f547402006-06-11 00:40:49 +00001358- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1359 clarify docs.
1360
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001361- The wsgiref package has been added to the standard library.
1362
Nick Coghlan676725d2006-06-08 13:54:49 +00001363- The functions update_wrapper() and wraps() have been added to the functools
1364 module. These make it easier to copy relevant metadata from the original
1365 function when writing wrapper functions.
1366
Tim Petersd6a9eef2006-06-05 01:48:21 +00001367- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1368 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001369
Martin v. Löwis3f767792006-06-04 19:36:28 +00001370- Patch #1359618: Speed up charmap encoder by using a trie structure
1371 for lookup.
1372
Tim Petersd609b1a2006-06-02 23:22:51 +00001373- The functions in the ``pprint`` module now sort dictionaries by key
1374 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1375 if and only if its display required more than one line, although that
1376 wasn't documented. The new behavior increases predictability; e.g.,
1377 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1378
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001379- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1380 (thanks for J. J. Lee).
1381
Georg Brandl2b330372006-05-28 20:23:12 +00001382- Patch #1496206: improve urllib2 handling of passwords with respect to
1383 default HTTP and HTTPS ports.
1384
George Yoshidaf3c65de2006-05-28 16:39:09 +00001385- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1386
Bob Ippolito7298f272006-05-23 18:43:47 +00001387- Patch #1281707: speed up gzip.readline.
1388
Georg Brandlb89316f2006-05-17 15:51:16 +00001389- Patch #1180296: Two new functions were added to the locale module:
1390 format_string() to get the effect of "format % items" but locale-aware,
1391 and currency() to format a monetary number with currency sign.
1392
Georg Brandle3a25832006-05-17 14:56:04 +00001393- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1394 and several features added, such as speed and geometry control.
1395
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001396- Patch #1488881: add support for external file objects in bz2 compressed
1397 tarfiles.
1398
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001399- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1400 stdout arguments, making it possible to redirect input and output
1401 for remote debugging.
1402
1403- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1404 a couple of issues, notably handling of long file names using the
1405 GNU LONGNAME extension.
1406
1407- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1408 new flag when ``name`` is already the name of an option flag.
1409
1410- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1411 package.
1412
1413- Patch #1472854: make the rlcompleter.Completer class usable on non-
1414 UNIX platforms.
1415
1416- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1417
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001418- Bug #1472827: correctly escape newlines and tabs in attribute values in
1419 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001449What's New in Python 2.5 alpha 2?
1450=================================
1451
1452*Release date: 27-APR-2006*
1453
1454Core and builtins
1455-----------------
1456
Thomas Heller1b046642006-04-18 18:51:06 +00001457- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1458 by converting these apis from macros into exported functions again:
1459
1460 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1461 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1462 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1463 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1464 PyRun_String Py_CompileString
1465
Martin v. Löwis45294a92006-04-18 06:24:08 +00001466- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1467
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001468- All uses of PyStructSequence_InitType have been changed to initialize
1469 the type objects only once, even if the interpreter is initialized
1470 multiple times.
1471
Neal Norwitz61546162006-04-14 05:20:28 +00001472- Bug #1454485, array.array('u') could crash the interpreter. This was
1473 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1474 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1475
1476- Py_UNICODE is unsigned. It was always documented as unsigned, but
1477 due to a bug had a signed value in previous versions.
1478
Tim Peters3a5e8b12006-04-11 01:44:07 +00001479- Patch #837242: ``id()`` of any Python object always gives a positive
1480 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1481 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001482 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001483 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001484
Tim Peters3a5e8b12006-04-11 01:44:07 +00001485 def __hash__(self):
1486 return id(self) # WRONG
1487
1488 because a hash result must be a (short) Python int but it was always
1489 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001490 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001491 was always usable as a hash value before this patch. That's no longer
1492 necessarily so.
1493
1494- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001495 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001496 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001497 #1454844)
1498
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001499- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1500 involving generators that have paused outside of any ``try`` or ``with``
1501 blocks. (In 2.5a1, a paused generator that was part of a reference
1502 cycle could not be garbage collected, regardless of whether it was
1503 paused in a ``try`` or ``with`` block.)

1510
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001511- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1512 fails with an error condition.
1513
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001514- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1515
1516- Bug #1117761: bsddb.*open() no longer raises an exception when using
1517 the cachesize parameter.
1518
1519- Bug #1149413: bsddb.*open() no longer raises an exception when using
1520 a temporary db (file=None) with the 'n' flag to truncate on open.
1521
1522- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1523 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001524
Armin Rigoa9017c32006-04-19 11:50:27 +00001525- Patch #1062014: AF_UNIX sockets under Linux have a special
1526 abstract namespace that is now fully supported.

1530
Peter Astrand7d1d4362006-07-14 14:04:45 +00001531- Bug #1223937: subprocess.CalledProcessError reports the exit status
1532 of the process using the returncode attribute, instead of
1533 abusing errno.
1534
Tim Peters711bf302006-04-25 03:31:36 +00001535- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1536 a doctest to be skipped (the code is not run, and the expected output
1537 or exception is ignored).
1538
Nick Coghlanda2268f2006-04-24 04:37:15 +00001539- Fixed contextlib.nested to cope with exceptions being raised and
1540 caught inside exit handlers.
1541
Greg Wardab05edc2006-04-23 03:47:58 +00001542- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1543 hex, octal, or binary; add ``append_const`` action; keep going if
1544 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1545 added ``epilog`` for better help generation).
1546
Tim Peters21fbd572006-04-21 21:18:10 +00001547- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1548 called from a thread spawned as a side effect of importing a module.
1549
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001550- The pydoc module now supports documenting packages contained in
1551 .zip or .egg files.
1552
1553- The pkgutil module now has several new utility functions, such
1554 as ``walk_packages()`` to support working with packages that are either
1555 in the filesystem or zip files.
1556
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001557- The mailbox module can now modify and delete messages from
1558 mailboxes, in addition to simply reading them. Thanks to Gregory
1559 K. Johnson for writing the code, and to the 2005 Google Summer of
1560 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001561
Tim Petersc7605f22006-04-17 21:12:33 +00001562- The ``__del__`` method of class ``local`` in module ``_threading_local``
1563 returned before accomplishing any of its intended cleanup.

Anthony Baxtere29002c2006-04-12 12:07:31 +00001571- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1572 Windows. Bug #1469163.
1573
Phillip J. Eby47032112006-04-11 01:07:43 +00001574- The warnings, linecache, inspect, traceback, site, and doctest modules
1575 were updated to work correctly with modules imported from zipfiles or
1576 via other PEP 302 __loader__ objects.

1584
Skip Montanaro262fb922006-04-21 02:31:07 +00001585- The pstats.Stats class accepts an optional stream keyword argument to
1586 direct output to an alternate file-like object.
1587
Anthony Baxter51bcb682006-04-05 14:51:42 +00001588Build
1589-----
1590
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001591- The Makefile now has a reindent target, which runs reindent.py on
1592 the library.
1593
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001594- Patch #1470875: Building Python with MS Free Compiler
1595

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001597
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001598- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1599 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001600 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001601 CXX from --with-cxx-main, see description in README.
1602
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001603- Patch #1429775: Link extension modules with the shared libpython.
1604
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001605- Fixed a libffi build problem on MIPS systems.
1606
Tim Peters8931ff12006-05-13 23:28:20 +00001607- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1608 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1609 and "%zu" for unsigned integers of type ``size_t``.
1610
Anthony Baxter51bcb682006-04-05 14:51:42 +00001611Tests
1612-----
1613
Nick Coghlanda2268f2006-04-24 04:37:15 +00001614- test_contextlib now checks contextlib.nested can cope with exceptions
1615 being raised and caught inside exit handlers.
1616
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001617- test_cmd_line now checks operation of the -m and -c command switches
1618
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001619- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1620 it separately and by hand. It also wasn't cleaning up its changes to
1621 the current Decimal context.
1622
Thomas Woutersabd08882006-04-26 15:53:30 +00001623- regrtest.py now has a -M option to run tests that test the new limits of
1624 containers, on 64-bit architectures. Running these tests is only sensible
1625 on 64-bit machines with more than two gigabytes of memory. The argument
1626 passed is the maximum amount of memory for the tests to use.

1635-------------
1636
Tim Petersb06d28c2006-05-12 01:57:59 +00001637- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1638
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001639- PEP 343: Added Context Types section to the library reference
1640 and attempted to bring other PEP 343 related documentation into
1641 line with the implementation and/or python-dev discussions.
1642
Tim Peters8dc73d22006-04-24 02:03:16 +00001643- Bug #1337990: clarified that ``doctest`` does not support examples
1644 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001647What's New in Python 2.5 alpha 1?
1648=================================
1649
Anthony Baxterebed3f62006-04-03 15:03:44 +00001650*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001651
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001652Core and builtins
1653-----------------
1654
Nick Coghlan43832302006-04-23 17:04:07 +00001655- PEP 338: -m command line switch now delegates to runpy.run_module
1656 allowing it to support modules in packages and zipfiles
1657
Martin v. Löwisc661b882006-04-20 04:54:23 +00001658- On Windows, .DLL is not an accepted file name extension for
1659 extension modules anymore; extensions are only found if they
1660 end in .PYD.
1661
Martin v. Löwisea62d252006-04-03 10:56:49 +00001662- Bug #1421664: sys.stderr.encoding is now set to the same value as
1663 sys.stdout.encoding.
1664
Neal Norwitz92e212f2006-04-03 04:48:37 +00001665- __import__ accepts keyword arguments.
1666
Georg Brandlccadf842006-03-31 18:54:53 +00001667- Patch #1460496: round() now accepts keyword arguments.
1668
Anthony Baxter262c00a2006-03-30 10:53:17 +00001669- Fixed bug #1459029 - unicode reprs were double-escaped.
1670
Hye-Shik Changd478f342006-03-23 12:32:36 +00001671- Patch #1396919: The system scope threads are reenabled on FreeBSD
1672 5.4 and later versions.
1673
Neal Norwitze98ccf62006-03-23 05:39:47 +00001674- Bug #1115379: Compiling a Unicode string with an encoding declaration
1675 now gives a SyntaxError.
1676
Georg Brandlabd1ff82006-03-18 07:59:59 +00001677- Previously, Python code had no easy way to access the contents of a
1678 cell object. Now, a ``cell_contents`` attribute has been added
1679 (closes patch #1170323).
1680
Tim Peterscf79aac2006-03-16 01:14:46 +00001681- Patch #1123430: Python's small-object allocator now returns an arena to
1682 the system ``free()`` when all memory within an arena becomes unused
1683 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1684 freed. Some applications will see a drop in virtual memory size now,
1685 especially long-running applications that, from time to time, temporarily
1686 use a large number of small objects. Note that when Python returns an
1687 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001688 platform C library will in turn return that memory to the operating system.
1689 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001690 appears to be effective at least on Microsoft C and gcc-based systems.
1691 Thanks to Evan Jones for hard work and patience.
1692
Georg Brandl533ff6f2006-03-08 18:09:27 +00001693- Patch #1434038: property() now uses the getter's docstring if there is
1694 no "doc" argument given. This makes it possible to legitimately use
1695 property() as a decorator to produce a read-only property.
1696
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001697- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1698 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1699 of requiring an int or long in slicing and a few other contexts, enabling
1700 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1701
Neal Norwitz995acdf2006-03-07 05:01:00 +00001702- Fixed various bugs reported by Coverity's Prevent tool.
1703
Brett Cannonbf364092006-03-01 04:25:17 +00001704- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1705 new exception base class, BaseException, which has a new message attribute.
1706 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1707 Raising a string exception now raises a DeprecationWarning.
1708
Thomas Woutersfb609f42006-02-28 16:37:25 +00001709- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1710 explicitly relative, using 'from .module import name' to mean 'from the same
1711 package as this module is in. Imports without dots still default to the
1712 old relative-then-absolute, unless 'from __future__ import
1713 absolute_import' is used.
1714
Brett Cannona7446e32006-02-27 23:39:10 +00001715- Properly check if 'warnings' raises an exception (usually when a filter set
1716 to "error" is triggered) when raising a warning for raising string
1717 exceptions.
1718
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001719- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001720 The name was removed from Include/code.h.
1721
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001722- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001723
Guido van Rossum1968ad32006-02-25 22:38:04 +00001724- Patch 1433928:
1725 - The copy module now "copies" function objects (as atomic objects).
1726 - dict.__getitem__ now looks for a __missing__ hook before raising
1727 KeyError.
1728
Tim Peters84ef21c2006-02-28 20:39:06 +00001729- PEP 343: with statement implemented. Needs ``from __future__ import
1730 with_statement``. Use of 'with' as a variable will generate a warning.
1731 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001732 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001733 The following objects have __context__ methods:
1734 - The built-in file type.
1735 - The thread.LockType type.
1736 - The following types defined by the threading module:
1737 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1738 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001739
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001740- Fix the encodings package codec search function to only search
1741 inside its own package. Fixes problem reported in patch #1433198.
1742
1743 Note: Codec packages should implement and register their own
1744 codec search function. PEP 100 has the details.
1745
Tim Peters9ea89d22006-06-04 03:26:02 +00001746- PEP 353: Using ``Py_ssize_t`` as the index type.
1747
1748- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1749 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1750 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1751 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1752 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001753
Neal Norwitzfc76d632006-01-10 06:03:13 +00001754- Patch #1400181, fix unicode string formatting to not use the locale.
1755 This is how string objects work. u'%f' could use , instead of .
1756 for the decimal point. Now both strings and unicode always use periods.
1757
Neal Norwitz671b9e32006-01-09 07:07:12 +00001758- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1759 configure would break checking curses.h.
1760
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001761- Bug #959576: The pwd module is now builtin. This allows Python to be
1762 built on UNIX platforms without $HOME set.
1763
Neal Norwitzc10978f2005-12-19 06:07:16 +00001764- Bug #1072182, fix some potential problems if characters are signed.
1765
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001766- Bug #889500, fix line number on SyntaxWarning for global declarations.
1767
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001768- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1769
Neal Norwitze7214a12005-12-18 05:03:17 +00001770- Support for converting hex strings to floats no longer works.
1771 This was not portable. float('0x3') now raises a ValueError.
1772
Barry Warsaw2a38a862005-12-18 01:27:35 +00001773- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001774 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001775 is now displayed in interactive prompt banner.
1776
Georg Brandlfa166682005-12-17 21:45:17 +00001777- Implementation of PEP 341 - Unification of try/except and try/finally.
1778 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001779 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001780
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001781- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1782 now encodes backslash correctly.
1783
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001784- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1785
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001786- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001787 and long longs.
1788
Neal Norwitz67715f02005-11-09 06:59:35 +00001789- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001790 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001791 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001792
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001793- Replaced most Unicode charmap codecs with new ones using the
1794 new Unicode translate string feature in the builtin charmap
1795 codec; the codecs were created from the mapping tables available
1796 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1797 encodings now include a mapping for the Apple logo)
1798
Tim Peterse3547fd2005-12-16 23:13:57 +00001799- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001800
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001801- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001802
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001803- A new AST parser implementation was completed. The abstract
1804 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001805 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001806
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001807- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001808 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1809
Neal Norwitz708e51a2005-10-03 04:48:15 +00001810- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1811
Neal Norwitz11bd1192005-10-03 00:54:56 +00001812- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1813 Provide a warning when a directory is passed on the command line.
1814
Neal Norwitz40d37812005-10-02 01:48:49 +00001815- Fix segfault with invalid coding.
1816
1817- SF bug #772896: unknown encoding results in MemoryError.
1818
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001819- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001820 supported a __len__() method which evaluated to False when the iterator
1821 was empty.
1822
Guido van Rossum630db602005-09-20 18:49:54 +00001823- On 64-bit platforms, when __len__() returns a value that cannot be
1824 represented as a C int, raise OverflowError.
1825
Skip Montanarof8948ca2005-09-19 03:54:46 +00001826- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001827 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001828
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001829- SF bug #893549: parsing keyword arguments was broken with a few format
1830 codes.
1831
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001832- Changes donated by Elemental Security to make it work on AIX 5.3
1833 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1834 bug #105470: test_pwd fails on 64bit system (Opteron).
1835
Guido van Rossum539c6622005-09-14 17:49:54 +00001836- Changes donated by Elemental Security to make it work on HP-UX 11 on
1837 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1838
Georg Brandl4550b8d2005-08-26 06:43:52 +00001839- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001840 (fixes bug #1119418).
1841
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001842- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1843
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001844- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1845 exceptions that cause a function to exit.
1846
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001847- The implementation of set() and frozenset() was revised to use its
1848 own internal data structure. Memory consumption is reduced by 1/3
1849 and there are modest speed-ups as well. The API is unchanged.
1850
Tim Petersde7990b2005-07-17 23:45:23 +00001851- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1852
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001853- SF bug #1229429: PyObject_CallMethod failed to decrement some
1854 reference counts in some error exit cases.
1855
Tim Petersecc6e6a2005-07-10 22:30:55 +00001856- SF bug #1185883: Python's small-object memory allocator took over
1857 a block managed by the platform C library whenever a realloc specified
1858 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001859 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001860 portable way to copy data from the C-managed block into Python's
1861 small-object space without risking a memory fault. Python's small-object
1862 realloc now leaves such blocks under the control of the platform C
1863 realloc.
1864
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001865- SF bug #1232517: An overflow error was not detected properly when
1866 attempting to convert a large float to an int in os.utime().
1867
Raymond Hettinger3296e692005-06-29 23:29:56 +00001868- SF bug #1224347: hex longs now print with lowercase letters just
1869 like their int counterparts.
1870
Michael W. Hudson188d4362005-06-20 16:52:57 +00001871- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1872 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1873 interpreter states; back out that fix and do a better job (see
1874 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1875 for a longer write-up of the problem).
1876
Michael W. Hudsondf888462005-06-03 14:41:55 +00001877- SF patch #1180995: marshal now uses a binary format by default when
1878 serializing floats.
1879
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001880- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1881 the routines that promise to produce IEEE 754 binary representations
1882 of floats now simply copy bytes around.
1883
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001884- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1885 278.
1886
Brett Cannonc3647ac2005-04-26 03:45:26 +00001887- patch #1109424: int, long, float, complex, and unicode now check for the
1888 proper magic slot for type conversions when subclassed. Previously the
1889 magic slot was ignored during conversion. Semantics now match the way
1890 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001891 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001892 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001893 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001894
Barry Warsawc8d907c2005-04-19 23:43:40 +00001895- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1896 NULL, now raise an AttributeError when attempting to set or delete the
1897 attribute. Previously a TypeError was raised, but this was inconsistent
1898 with the equivalent pure-Python implementation.
1899
Michael W. Hudson774479c2005-04-18 08:46:17 +00001900- It is now safe to call PyGILState_Release() before
1901 PyEval_InitThreads() (note that if there is reason to believe there
1902 are multiple threads around you still must call PyEval_InitThreads()
1903 before using the Python API; this fix is for extension modules that
1904 have no way of knowing if Python is multi-threaded yet).
1905
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001906- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1907 disabled caused a crash.
1908
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001909- Bug #1165306: instancemethod_new allowed the creation of a method
1910 with im_class == im_self == NULL, which caused a crash when called.
1911
Tim Petersecc6e6a2005-07-10 22:30:55 +00001912- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001913 fixes the crash seen in bug #1165761
1914
Raymond Hettinger96229b12005-03-11 06:49:40 +00001915- Added two new builtins, any() and all().
1916
Brett Cannon409d8f22005-03-05 06:47:57 +00001917- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001918 (e.g., ``class C(): pass`` is no longer a syntax error).
1919 Patch #1176012 added support to the 'parser' module and 'compiler' package
1920 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001921
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001922- Patch #1115086: Support PY_LONGLONG in structmember.
1923
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001924- Bug #1155938: new style classes did not check that __init__() was
1925 returning None.
1926
Tim Petersecc6e6a2005-07-10 22:30:55 +00001927- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001928 ('\') with a specific error message.
1929
Martin v. Löwisff232d72005-03-03 09:24:38 +00001930- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1931
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001932- Bug #1124295: the __name__ attribute of file objects was
1933 inadvertently made inaccessible in restricted mode.
1934
Tim Petersecc6e6a2005-07-10 22:30:55 +00001935- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001936 an ferror() call.
1937
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001938- min() and max() now support key= arguments with the same meaning as in
1939 list.sort().
1940
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001941- The peephole optimizer now performs simple constant folding in expressions:
1942 (2+3) --> (5).
1943
Raymond Hettingera422c342005-01-11 03:03:27 +00001944- set and frozenset objects can now be marshalled. SF #1098985.
1945
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001946- Bug #1077106: Poor argument checking could cause memory corruption
1947 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001948
Jeremy Hyltonab630502005-02-04 18:44:06 +00001949- The parser did not complain about future statements in illegal
1950 positions. It once again reports a syntax error if a future
1951 statement occurs after anything other than a doc string.
1952
Neil Schemenauercf52c072005-08-12 17:34:58 +00001953- Change the %s format specifier for str objects so that it returns a
1954 unicode instance if the argument is not an instance of basestring and
1955 calling __str__ on the argument returns a unicode instance.
1956
Tim Petersf4e69282006-02-27 17:15:31 +00001957- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1958 current thread state when the auto-GIL-state machinery knows about
1959 it (since the thread state is being deleted, continuing to remember it
1960 can't help, but can hurt if another thread happens to get created with
1961 the same thread id).
1962
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001963Extension Modules
1964-----------------
1965

Tim Petersc9d78aa2006-03-26 23:27:58 +00001978 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001979 util, whatsound, whrandom, zmod
1980
1981- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1982
1983- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001984 is deprecated. The undocumented re.engine variable no longer exists.
1985
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001986- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1987 SS2 (single-shift 2) escape sequences correctly.
1988
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001989- The unicodedata module was updated to the 4.1 version of the Unicode
1990 database. The 3.2 version is still available as unicodedata.db_3_2_0
1991 for applications that require this specific version (such as IDNA).
1992
Neal Norwitzb62c4332006-03-04 18:35:47 +00001993- The timing module is no longer built by default. It was deprecated
1994 in PEP 4 in Python 2.0 or earlier.
1995
Guido van Rossum1968ad32006-02-25 22:38:04 +00001996- Patch 1433928: Added a new type, defaultdict, to the collections module.
1997 This uses the new __missing__ hook behavior added to dict (see above).
1998
Georg Brandldbd83392006-02-20 09:42:33 +00001999- Bug #854823: socketmodule now builds on Sun platforms even when
2000 INET_ADDRSTRLEN is not defined.
2001
Georg Brandlf4f44152006-02-18 22:29:33 +00002002- Patch #1393157: os.startfile() now has an optional argument to specify
2003 a "command verb" to invoke on the file.
2004
Neal Norwitz082b2df2006-02-07 07:04:46 +00002005- Bug #876637, prevent stack corruption when socket descriptor
2006 is larger than FD_SETSIZE.
2007
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00002008- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
2009 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
2010 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
2011
Martin v. Löwis57a34e82006-02-04 19:12:37 +00002012- Patch #1422385: The nis module now supports access to domains other
2013 than the system default domain.
2014
Martin v. Löwis14694662006-02-03 12:54:16 +00002015- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2016 are reported, the limit on path name lengths is removed, and stat reports
2017 WindowsError now (instead of OSError).
2018
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002019- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.
2020
Neal Norwitz62a21122006-01-25 05:21:55 +00002021- Bug #1413192, fix seg fault in bsddb if a transaction was deleted
2022 before the env.

2029 Also fix ungetmouse() which did not accept arguments properly.
2030 The code now conforms to the documented signature.
2031
Neal Norwitz5e3d8622006-01-09 06:24:35 +00002032- Bug #1400115, Fix segfault when calling curses.panel.userptr()
2033 without prior setting of the userptr.
2034

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002153- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2154 been renamed to have only a single underscore prefix. This was done to
2155 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002156
Nick Coghlan43832302006-04-23 17:04:07 +00002157- PEP 338: new module runpy defines a run_module function to support
2158 executing modules which provide access to source code or a code object
2159 via the PEP 302 import mechanisms.
2160
Anthony Baxter93f5b932006-04-03 08:05:07 +00002161- The email module's parsedate_tz function now sets the daylight savings
2162 flag to -1 (unknown) since it can't tell from the date whether it should

2169 in attribute values.
2170
Anthony Baxterc51ee692006-04-01 00:57:31 +00002171- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002172 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002173 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002174 module will not be built.
2175
Tim Petersc17976e2006-04-01 00:26:53 +00002176- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2177 aren't officially supported here, and trying to use them will probably
2178 raise an exception some day. But dicts have been allowed, and "mostly
2179 worked", so support for them won't go away without warning.
2180
Georg Brandl338ef7d2006-03-31 18:42:16 +00002181- Bug #1445068: getpass.getpass() can now be given an explicit stream
2182 argument to specify where to write the prompt.
2183

Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002192- Queue.Queue objects now support .task_done() and .join() methods
2193 to make it easier to monitor when daemon threads have completed
2194 processing all enqueued tasks. Patch #1455676.
2195

2199
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002200- email 4.0 package now integrated. This is largely the same as the email 3.0
2201 package that was included in Python 2.3, except that PEP 8 module names are
2202 now used (e.g. mail.message instead of email.Message). The MIME classes
2203 have been moved to a subpackage (e.g. email.mime.text instead of
2204 email.MIMEText). The old names are still supported for now. Several
2205 deprecated Message methods have been removed and lots of bugs have been
2206 fixed. More details can be found in the email package documentation.
2207
Walter Dörwald40108c92006-03-27 08:15:44 +00002208- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2209 (a subclass of tuple) that provides incremental decoders and encoders
2210 (a way to use stateful codecs without the stream API). Python functions
2211 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2212 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2213 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002214
Walter Dörwald067db482006-03-15 22:17:27 +00002215- Patch #1359365: Calling next() on a closed StringIO.String object raises
2216 a ValueError instead of a StopIteration now (like file and cString.String do).
2217 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2218 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002219
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002220- A regrtest option -w was added to re-run failed tests in verbose mode.

Martin v. Löwis3e865952006-01-24 15:51:21 +00002268 specifications, raises IOErrors when proxies for unsupported protocols
2269 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00002292 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2293 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2294 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2295 Ronald L. Rivest offered this advice for Python:
2296
2297 "The consensus of researchers in this area (at least as
2298 expressed at the NIST Hash Function Workshop 10/31/05),
2299 is that SHA-256 is a good choice for the time being, but
2300 that research should continue, and other alternatives may
2301 arise from this research. The larger SHA's also seem OK."

2356 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002357 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002358

2396 Bug #1224621.
2397
Raymond Hettinger68c04532005-06-10 11:05:19 +00002398- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002399 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002400 the generate_tokens() function now accepts a callable argument that
2401 terminates by raising StopIteration.
2402
Georg Brandl9166e1a2005-06-04 09:20:03 +00002403- Bug #1196315: fix weakref.WeakValueDictionary constructor.

2411 class at all.
2412
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002413- distutils.commands.upload was added to support uploading distribution

2415
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002416- distutils.commands.register now encodes the data as UTF-8 before posting
2417 them to PyPI.
2418
Raymond Hettinger267b8682005-03-27 10:47:39 +00002419- decimal operator and comparison methods now return NotImplemented
2420 instead of raising a TypeError when interacting with other types. This
2421 allows other classes to implement __radd__ style methods and have them
2422 work as expected.
2423
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002424- Bug #1163325: Decimal infinities failed to hash. Attempting to
2425 hash a NaN raised an InvalidOperation instead of a TypeError.
2426
Tim Petersecc6e6a2005-07-10 22:30:55 +00002427- Patch #918101: Add tarfile open mode r|* for auto-detection of the

2461
Guido van Rossumd0641422005-02-03 15:01:24 +00002462- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2463 disables recursive traversal through instance attributes, which can
2464 be exploited in various ways.
2465
Tim Peterse3547fd2005-12-16 23:13:57 +00002466- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002467 flags on the HTTP listening socket.
2468
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002469- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2470 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2471
Fred Drakefbdeaad2006-07-29 16:56:15 +00002472- Patches #893642, #1039083: add allow_none, encoding arguments to
2473 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002474
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002475- Bug #1110478: Revert os.environ.update to do putenv again.
2476
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002477- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2478
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002479- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2480
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002481- Enhancements to the csv module:
2482
2483 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002484 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002485 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002486 + Dialect parameter parsing has been re-implemented to improve error
2487 reporting.
2488 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2489 dictates.
2490 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002491 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002492 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002493 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2494 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002495 + reader now allows \r characters to be quoted (previously it only allowed
2496 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002497 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002498 + Dialect classes passed to the module are no longer instantiated by
2499 the module before being parsed (the former validation scheme required
2500 this, but the mechanism was unreliable).
2501 + The dialect registry now contains instances of the internal
2502 C-coded dialect type, rather than references to python objects.
2503 + the internal c-coded dialect type is now immutable.
2504 + register_dialect now accepts the same keyword dialect specifications
2505 as the reader and writer, allowing the user to register dialects
2506 without first creating a dialect class.
2507 + a configurable limit to the size of parsed fields has been added -
2508 previously, an unmatched quote character could result in the entire
2509 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002510 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002511 the parser field size limit (returning the former limit). The initial
2512 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002513 + A line_num attribute has been added to the reader object, which tracks
2514 the number of lines read from the source iterator. This is not
2515 the same as the number of records returned, as records can span
2516 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002517 + reader and writer objects were not being registered with the cyclic-GC.
2518 This has been fixed.
2519
Brett Cannone6539c42005-01-08 02:43:53 +00002520- _DummyThread objects in the threading module now delete self.__block that is
2521 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2522 lock primitives tend to be limited in number and thus should not be wasted on
2523 a _DummyThread object. Fixes bug #1089632.
2524
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002525- The imghdr module now detects Exif files.
2526
Raymond Hettinger6065d322004-12-20 23:51:53 +00002527- StringIO.truncate() now correctly adjusts the size attribute.
2528 (Bug #951915).
2529
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002530- locale.py now uses an updated locale alias table (built using
2531 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2532 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002533 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002534
Raymond Hettinger3557f422004-12-07 12:02:02 +00002535- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2536
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002537- the pickle module no longer accepts the deprecated None option in the
2538 args tuple returned by __reduce__().
2539
Brett Cannon84667c02004-12-07 03:25:18 +00002540- optparse now optionally imports gettext. This allows its use in setup.py.
2541
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002542- the pickle module no longer uses the deprecated bin parameter.
2543
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002544- the shelve module no longer uses the deprecated binary parameter.
2545
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002546- the pstats module no longer uses the deprecated ignore() method.
2547
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002548- the filecmp module no longer uses the deprecated use_statcache argument.
2549
Raymond Hettinger664347b2004-12-04 21:21:53 +00002550- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2551 extended or overridden by subclasses. Formerly, the subclassed method would
2552 be ignored by the rest of the module. (Bug #1078905).
2553
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002554- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002555 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002556
Walter Dörwald36733692004-12-22 12:50:50 +00002557- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2558 once when a size argument is given. This prevents a buffer overflow in the
2559 tokenizer with very long source lines.

Barry Warsaw538561e2006-01-01 21:48:54 +00002561- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2562 immediately after creating the object, without any intervening
2563 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002564
Skip Montanaro05885812005-01-16 20:48:27 +00002565- The reconvert.quote function can now emit triple-quoted strings. The
2566 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002567
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002568- ``UserString.MutableString`` now supports negative indices in
2569 ``__setitem__`` and ``__delitem__``
2570
Greg Ward40407942005-03-05 02:53:17 +00002571- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2572 correctly.
2573
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002574- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2575 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2576 character even if the user has passed a size parameter to get a proper
2577 line ending. Remove the special handling of a "\r\n" that has been split
2578 between two lines.
2579
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002580- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2581 about illegal code points. The codec now supports PEP 293 style error
2582 handlers.
2583
Walter Dörwald78a78b02005-09-01 12:04:29 +00002584- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002585 from the input stream, so that the output is a byte string in the correct
2586 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002587
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002588- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2589 considering it exactly like a '*'.
2590
Walter Dörwald007f8df2005-10-09 19:42:27 +00002591- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2592 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002593
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002594- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2595

2597 touch the recursion limit.
2598
Walter Dörwald58917a62006-03-31 15:26:22 +00002599- Bug #947906: An object oriented interface has been added to the calendar
2600 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002601 called as a script (e.g. via ``python -mcalendar``). Localized month and
2602 weekday names can be ouput (even if an exotic encoding is used) using
2603 special classes that use unicode.

2607
Neal Norwitz602d3392006-03-31 08:21:40 +00002608- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2609 by using -mieee gcc option.
2610

2612
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002613- Build support for Win64-AMD64 was added.
2614
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002615- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2616
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002617- Patch #881820: look for openpty and forkpty also in libbsd.
2618
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002619- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2620 The zlib module is now builtin on Windows.
2621
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002622- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2623
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002624- Bug #1189330: configure did not correctly determine the necessary
2625 value of LINKCC if python was built with GCC 4.0.
2626
Trent Mick8321b422005-07-26 02:29:21 +00002627- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2628 vulnerability in zlib 1.2.1 and 1.2.2.
2629
Brett Cannon08cd5982005-04-24 22:26:38 +00002630- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2631 flags that change binary compatibility. Changes were also made to
2632 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002633 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002634
Bob Ippolitoed233462005-03-29 13:47:59 +00002635- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2636 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2637 no longer exists). This configure patch makes things right.
2638
Martin v. Löwise2713be2005-03-08 15:03:08 +00002639- Bug #1158607: Build with --disable-unicode again.
2640
Brett Cannon46d96232005-02-16 00:07:19 +00002641- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2642 defined. Discovered as a result of not being able to build on OS X.
2643
Brett Cannon516592f2004-12-07 00:42:59 +00002644- setup.py now uses the directories specified in LDFLAGS using the -L option
2645 and in CPPFLAGS using the -I option for adding library and include
2646 directories, respectively, for compiling extension modules against. This has
2647 led to the core being compiled using the values in CPPFLAGS. It also removes
2648 the need for the special-casing of both DarwinPorts and Fink for darwin since
2649 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2650 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2651 Fink, ``-I/opt/local/include`` for DarwinPorts).
2652
Brett Cannon43802422005-02-10 20:48:03 +00002653- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2654 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2655 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2656 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002658C API
2659-----
2660
Tim Petersc9d78aa2006-03-26 23:27:58 +00002661- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2662 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2663 is obtained via the ``PyObject_`` family, it must be released via the
2664 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2665 always been officially true, but when Python's small-object allocator was
2666 introduced, an attempt was made to cater to a few extension modules
2667 discovered at the time that obtained memory via ``PyObject_New`` but
2668 released it via ``PyMem_DEL``. It's years later, and if such code still
2669 exists it will fail now (probably with segfaults, but calling wrong
2670 low-level memory management functions can yield many symptoms).
2671
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002672- Added a C API for set and frozenset objects.
2673
Raymond Hettinger66517482004-12-03 11:45:13 +00002674- Removed PyRange_New().
2675
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002676- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2677 mapping argument now. This string is used as a mapping table. Byte values
2678 greater than the length of the string and 0xFFFE are treated as undefined
2679 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002686
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002687- Patch #1276356: New resource "urlfetch" is implemented. This enables
