Neal Norwitzff4b63b2006-08-04 04:50:21 +0000622
623Core and builtins
624-----------------
625
Neal Norwitz24b6f202006-09-05 04:43:56 +0000626- Fix infinite recursion when subclassing long and overriding __hash__.
627
628- Fix concatenation (+=) of long strings.
629
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000630- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000631 compared equal or unequal to a string and a UnicodeDecodeError
632 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000633
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000634 Instead, the equal (==) and unequal (!=) comparison operators will
635 now issue a UnicodeWarning and interpret the two objects as
636 unequal. The UnicodeWarning can be filtered as desired using
637 the warning framework, e.g. silenced completely, turned into an
638 exception, logged, etc.
639
640 Note that compare operators other than equal and unequal will still
641 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000642
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000643- Fix segfault when doing string formatting on subclasses of long.
644
645- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
646 with new-style classes.
647
648- Fix bug related to __len__ functions returning negative values with
649 classic classes.
650
651- Patch #1538606, Fix __index__() clipping. There were some problems
652 discovered with the API and how integers that didn't fit into Py_ssize_t
653 were handled. This patch attempts to provide enough alternatives
654 to effectively use __index__.
655
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000656- Bug #1536021: __hash__ may now return long int; the final hash
657 value is obtained by invoking hash on the long int.
658
Thomas Hellerab1049c2006-08-08 17:37:00 +0000659- Bug #1536786: buffer comparison could emit a RuntimeWarning.
660
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000661- Bug #1535165: fixed a segfault in input() and raw_input() when
662 sys.stdin is closed.
663
Thomas Heller74d36f02006-08-04 18:17:40 +0000664- On Windows, the PyErr_Warn function is now exported from
665 the Python dll again.
666
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000667- Bug #1191458: tracing over for loops now produces a line event
668 on each iteration. Fixing this problem required changing the .pyc
669 magic number. This means that .pyc files generated before 2.5c1
670 will be regenerated.
671
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000672- Bug #1333982: string/number constants were inappropriately stored
673 in the byte code and co_consts even if they were not used, ie
674 immediately popped off the stack.
675
Georg Brandle9462c72006-08-04 18:03:37 +0000676- Fixed a reference-counting problem in property().
677
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000678
679Library
680-------
681
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000682- Fix a bug in the ``compiler`` package that caused invalid code to be
683 generated for generator expressions.
684
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000685- The distutils version has been changed to 2.5.0. The change to
686 keep it programmatically in sync with the Python version running
687 the code (introduced in 2.5b3) has been reverted. It will continue
688 to be maintained manually as static string literal.
689
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000690- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000691 and this cannot be converted to the required C type, an exception is
692 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000693 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000694
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000695- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000696 an exception.
697
Tim Peterscbdd3502006-09-05 01:47:53 +0000698- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000699 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000700 workarounds for clocks with low resolution, to stop the code yielding
701 duplicate UUIDs.
702
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000703- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
704 before raising SystemExit, allowing IDLE to honor quit() and exit().
705
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000706- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
707
Georg Brandl7a1af772006-08-14 21:55:28 +0000708- Patch #1536071: trace.py should now find the full module name of a
709 file correctly even on Windows.
710
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000711- logging's atexit hook now runs even if the rest of the module has
712 already been cleaned up.
713
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000714- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000715
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000716- Bug #1531405, format_exception no longer raises an exception if
717 str(exception) raised an exception.
718
Neil Schemenauer06ded092006-08-04 16:20:30 +0000719- Fix a bug in the ``compiler`` package that caused invalid code to be
720 generated for nested functions.
721
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000722
723Extension Modules
724-----------------

727
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000728- Patch #1511317: don't crash on invalid hostname (alias) info.
729
Georg Brandl3335a7a2006-08-14 21:42:55 +0000730- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
731 raises the correct exceptions.
732
Thomas Heller1ce433e2006-08-14 16:20:04 +0000733- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
734 '-no-stack-protector' compiler flag for OpenBSD has been removed.
735
Thomas Heller86720042006-08-14 11:17:48 +0000736- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
737 uses the _as_parameter_ attribute when objects are passed to foreign
738 function calls. The ctypes version number was changed to 1.0.1.
739
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000740- Bug #1530559, struct.pack raises TypeError where it used to convert.
741 Passing float arguments to struct.pack when integers are expected
742 now triggers a DeprecationWarning.
743
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000744

Andrew MacIntyre16ee33a2006-08-06 12:37:03 +0000755- test_threading now skips testing alternate thread stack sizes on
756 platforms that don't support changing thread stack size.
757
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000758

Neal Norwitzff4b63b2006-08-04 04:50:21 +0000765Build
766-----
767
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +0000768- Bug #1535502, build _hashlib on Windows, and use masm assembler
769 code in OpenSSL.
770
Thomas Hellerdb7b4432006-08-04 19:49:31 +0000771- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

Neal Norwitzff4b63b2006-08-04 04:50:21 +0000775
Tim Peters4643c2f2006-08-10 22:45:34 +0000776C API
777-----
778
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000779- New API for Unicode rich comparisons: PyUnicode_RichCompare()

Fred Drake53912162006-07-29 13:22:49 +0000787What's New in Python 2.5 beta 3?
788================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000789
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000790*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000791
792Core and builtins
793-----------------
794
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000795- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000796 returned a long (see PEP 353).
797
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000798- Bug #1515471: string.replace() accepts character buffers again.
799
Neal Norwitz07aadb12006-07-30 06:55:48 +0000800- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
801 This provides the proper warning for struct.pack().
802 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
803
Neal Norwitz0d62a062006-07-30 06:53:31 +0000804- Patch #1531113: Fix augmented assignment with yield expressions.
805 Also fix a SystemError when trying to assign to yield expressions.
806
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000807- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
808 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
809 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
810 excessive filesystem operations during imports.
811
Tim Petersbc24eee2006-07-27 01:14:53 +0000812- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
813 operations on signed longs that are formally undefined by C.
814 Unfortunately, at least one compiler now cares about that, so complicated
815 the code to make that compiler happy again.
816
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000817- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
818
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000819- Patch #1232023: Stop including current directory in search
820 path on Windows.
821
Neal Norwitze1fdb322006-07-21 05:32:28 +0000822- Fix some potential crashes found with failmalloc.
823
Neal Norwitze7563102006-07-17 01:00:16 +0000824- Fix warnings reported by Klocwork's static analysis tool.
825
Neal Norwitz84be93b2006-07-16 01:50:38 +0000826- Bug #1512814, Fix incorrect lineno's when code within a function
827 had more than 255 blank lines.
828
Georg Brandl9dceedb2006-07-12 15:31:17 +0000829- Patch #1521179: Python now accepts the standard options ``--help`` and
830 ``--version`` as well as ``/?`` on Windows.
831
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000832- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000833 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000834 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000835
Tim Peters112aad32006-07-19 00:03:19 +0000836- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000837 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000838 new ``sys._current_frames()`` returns a dictionary with one entry,
839 mapping the faux "thread id" 0 to the current frame.
840
Ronald Oussoren3075e162006-07-25 20:28:55 +0000841- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000842
Ronald Oussoren3075e162006-07-25 20:28:55 +0000843
Neal Norwitza1f10902006-07-12 07:28:29 +0000844Library
845-------
846
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000847- Correction of patch #1455898: In the mbcs decoder, set final=False
848 for stream decoder, but final=True for the decode function.
849
Georg Brandl07fec3a2006-08-01 18:49:24 +0000850- os.urandom no longer masks unrelated exceptions like SystemExit or
851 KeyboardInterrupt.
852
Tim Peters4643c2f2006-08-10 22:45:34 +0000853- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000854 shutil.copytree on Windows
855
Georg Brandle34ac7c2006-07-30 11:07:23 +0000856- Bug #1002398: The documentation for os.path.sameopenfile now correctly
857 refers to file descriptors, not file objects.
858
Tim Peterscbdd3502006-09-05 01:47:53 +0000859- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000860 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000861 #1513611, and probably others.
862
Georg Brandledd9b0d2006-07-29 09:33:26 +0000863- Bug #1441397: The compiler module now recognizes module and function
864 docstrings correctly as it did in Python 2.4.
865
Tim Peters6f681472006-07-27 23:44:37 +0000866- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
867 lost that tests are sorted by name before being run. This rarely
868 matters for well-written tests, but can create baffling symptoms if
869 side effects from one test to the next affect outcomes. ``DocTestFinder``
870 has been changed to sort the list of tests it returns.
871
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000872- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000873 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000874
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000875- Bug #978833: Really close underlying socket in _socketobject.close.
876
Georg Brandldb232dc2006-08-20 13:15:43 +0000877- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
878 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000879
Georg Brandlcf0c1722006-07-26 07:23:32 +0000880- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
881 to recursive calls and call it with the failing package name.
882
Martin v. Löwis0b483032006-07-25 09:53:12 +0000883- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
884

886 value in the traceback module.
887
Greg Ward48fae7a2006-07-23 16:05:51 +0000888- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
889
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000890- Patch #1524429: Use repr() instead of backticks in Tkinter again.
891
Brett Cannoncaebe222006-07-18 04:41:36 +0000892- Bug #1520914: Change time.strftime() to accept a zero for any position in its
893 argument tuple. For arguments where zero is illegal, the value is forced to
894 the minimum value that is correct. This is to support an undocumented but
895 common way people used to fill in inconsequential information in the time
896 tuple pre-2.4.
897
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000898- Patch #1220874: Update the binhex module for Mach-O.
899
Barry Warsawb110bad2006-07-21 14:51:07 +0000900- The email package has improved RFC 2231 support, specifically for
901 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
902 (name*0=<blah>) parameter continuations. This may change the types of
903 values returned from email.message.Message.get_param() and friends.
904 Specifically in some cases where non-encoded continuations were used,
905 get_param() used to return a 3-tuple of (None, None, string) whereas now it
906 will just return the string (since non-encoded continuations don't have
907 charset and language parts).
908
909 Also, whereas % values were decoded in all parameter continuations, they are
910 now only decoded in encoded parameter parts.
911
Ronald Oussoren3075e162006-07-25 20:28:55 +0000912- Bug #1517990: IDLE keybindings on MacOS X now work correctly
913
914- Bug #1517996: IDLE now longer shows the default Tk menu when a
915 path browser, class browser or debugger is the frontmost window on MacOS X
916
Barry Warsaw00decd72006-07-27 23:43:15 +0000917- Patch #1520294: Support for getset and member descriptors in types.py,
918 inspect.py, and pydoc.py. Specifically, this allows for querying the type
919 of an object against these built-in types and more importantly, for getting
920 their docstrings printed in the interactive interpreter's help() function.

925
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000926- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
927 a socket operation on a socket with a timeout, the exception will be
928 caught correctly. Previously, the exception was not caught.
929
Thomas Heller1393d6a2006-07-28 21:43:20 +0000930- Patch #1529514: The _ctypes extension is now compiled on more
931 openbsd target platforms.
932
Tim Peters9cab5932006-07-28 00:30:00 +0000933- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
934 a memory leak, affecting pickles and deep copies.
935
Tim Petersbc24eee2006-07-27 01:14:53 +0000936- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

940
Thomas Hellerce049a02006-07-14 17:51:14 +0000941- Patch #1521817: Index range checking on ctypes arrays containing
942 exactly one element enabled again. This allows iterating over these
943 arrays, without the need to check the array size before.
944
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000945- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000946 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000947 /dev/null in certain cases; this is now fixed.
948
Thomas Heller47d7a062006-07-12 08:43:47 +0000949- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
950 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000951
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000952- Because of a misspelled preprocessor symbol, ctypes was always
953 compiled without thread support; this is now fixed.
954
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000955- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
956 methods now allow their database parameter to be None as the
957 sleepycat API allows.
958
Matt Flemingec926502006-07-28 11:27:27 +0000959- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
960 bluetooth API compared with Linux and FreeBSD.
961
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000962Tests
963-----
964
965- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
966 how long the test file should take to play. Now accepts taking 2.93 secs
967 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
968
Georg Brandl4793aa32006-07-28 18:31:39 +0000969- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
970 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
971 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +0000972

976- Bug #1439538: Drop usage of test -e in configure as it is not portable.
977
Ronald Oussoren26cad082006-08-01 21:00:57 +0000978Mac
979---
980
981- PythonLauncher now works correctly when the path to the script contains
982 characters that are treated specially by the shell (such as quotes).
983
984- Bug #1527397: PythonLauncher now launches scripts with the working directory
985 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000986 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000987 expect.

995Core and builtins
996-----------------
997
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000998- Bug #1441486: The literal representation of -(sys.maxint - 1)
999 again evaluates to a int object, not a long.
1000
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001001- Bug #1501934: The scope of global variables that are locally assigned
1002 using augmented assignment is now correctly determined.
1003
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001004- Bug #927248: Recursive method-wrapper objects can now safely
1005 be released.
1006
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001007- Bug #1417699: Reject locale-specific decimal point in float()
1008 and atof().
1009
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001010- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1011 omit a default "error" argument for NULL pointer. This allows
1012 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001013
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001014- Bug #1519018: 'as' is now validated properly in import statements.
1015
Neal Norwitz28746ab2006-07-09 22:14:42 +00001016- On 64 bit systems, int literals that use less than 64 bits are
1017 now ints rather than longs.
1018
Neal Norwitzed657552006-07-10 00:04:44 +00001019- Bug #1512814, Fix incorrect lineno's when code at module scope
1020 started after line 256.
1021
Tim Peters32a83612006-07-10 21:08:24 +00001022- New function ``sys._current_frames()`` returns a dict mapping thread
1023 id to topmost thread stack frame. This is for expert use, and is
1024 especially useful for debugging application deadlocks. The functionality
1025 was previously available in Fazal Majid's ``threadframe`` extension
1026 module, but it wasn't possible to do this in a wholly threadsafe way from
1027 an extension.
1028

Martin v. Löwis8d656812006-07-10 07:23:48 +00001038 environment variable to be set in order to the SDK environment
1039 for finding the compiler, include files, etc.

1044
Thomas Woutersadd19112006-07-05 11:03:49 +00001045- string.Template() now correctly handles tuple-values. Previously,
1046 multi-value tuples would raise an exception and single-value tuples would
1047 be treated as the value they contain, instead.
1048
Martin v. Löwisede77f52006-07-03 13:01:35 +00001049- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1050 even if some data are received.
1051
Martin v. Löwis45482392006-07-03 12:28:58 +00001052- Bug #1267547: Put proper recursive setup.py call into the

1056 degrees and radians.
1057
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001058- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001059 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001060

1062 is created.
1063
Martin v. Löwis7596e832006-07-01 15:33:37 +00001064- Bug #1513223: .close() of a _socketobj now releases the underlying
1065 socket again, which then gets closed as it becomes unreferenced.

1068 attribute values.
1069
1070- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1071 sgmllib ('[' and ']' were not accepted).
1072
Georg Brandl1be63af2006-06-28 20:23:25 +00001073- Fix a bug in the turtle module's end_fill function.
1074
Brett Cannon53ab5b72006-06-22 16:49:14 +00001075- Bug #1510580: The 'warnings' module improperly required that a Warning
1076 category be either a types.ClassType and a subclass of Warning. The proper
1077 check is just that it is a subclass with Warning as the documentation states.
1078
Georg Brandlad29e632006-06-21 17:45:17 +00001079- The compiler module now correctly compiles the new try-except-finally
1080 statement (bug #1509132).
1081
Neal Norwitz60373cd2006-06-22 06:30:50 +00001082- The wsgiref package is now installed properly on Unix.
1083

1085 shutdown when fileConfig() was called multiple times.
1086
Gerhard Häring762fbd32006-07-02 17:48:30 +00001087- The sqlite3 module did cut off data from the SQLite database at the first
1088 null character before sending it to a custom converter. This has been fixed
1089 now.
1090
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001091Extension Modules
1092-----------------
1093
Tim Peters112aad32006-07-19 00:03:19 +00001094- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1095 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1096 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001097
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001098- Assigning None to pointer type fields in ctypes structures possible
1099 overwrote the wrong fields, this is fixed now.
1100
1101- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1102 on non-Windows platforms.
1103
1104- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1105 integer or long, without range checking.
1106
1107- Patch #1517790: It is now possible to use custom objects in the ctypes
1108 foreign function argtypes sequence as long as they provide a from_param
1109 method, no longer is it required that the object is a ctypes type.
1110
1111- The '_ctypes' extension module now works when Python is configured
1112 with the --without-threads option.
1113
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001114- Bug #1513646: os.access on Windows now correctly determines write
1115 access, again.
1116
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001117- Bug #1512695: cPickle.loads could crash if it was interrupted with
1118 a KeyboardInterrupt.

Neal Norwitza12aa882006-07-06 06:45:08 +00001120- Bug #1296433: parsing XML with a non-default encoding and
1121 a CharacterDataHandler could crash the interpreter in pyexpat.
1122

1129
Tim Peters32a83612006-07-10 21:08:24 +00001130- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001131 Previously, the slight difference could cause compilation errors of the
1132 'zlib' module on systems with more than one version of zlib.
1133
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001134- The MSI compileall step was fixed to also support a TARGETDIR
1135 with spaces in it.

1150-------------
1151
Nick Coghlan2d792252006-07-06 13:47:18 +00001152- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1153 documentation for the warnings module.
1154
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001155- Patch #1509163: MS Toolkit Compiler no longer available.

1166-----------------
1167
Georg Brandla56b9152006-06-19 06:35:54 +00001168- Patch #1507676: Error messages returned by invalid abstract object operations
1169 (such as iterating over an integer) have been improved and now include the
1170 type of the offending object to help with debugging.
1171
Brett Cannonea3912b2006-06-13 21:46:41 +00001172- Bug #992017: A classic class that defined a __coerce__() method that returned
1173 its arguments swapped would infinitely recurse and segfault the interpreter.
1174
Neal Norwitz909eb122006-06-12 02:13:21 +00001175- Fix the socket tests so they can be run concurrently.
1176
Neal Norwitzb9845e72006-06-12 02:11:18 +00001177- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001178 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001179
Brett Cannon22565aa2006-06-09 22:31:23 +00001180- Bug #532646: object.__call__() will continue looking for the __call__
1181 attribute on objects until one without one is found. This leads to recursion
1182 when you take a class and set its __call__ attribute to an instance of the
1183 class. Originally fixed for classic classes, but this fix is for new-style.
1184 Removes the infinite_rec_3 crasher.
1185
Georg Brandl24250812006-06-09 18:45:48 +00001186- The string and unicode methods startswith() and endswith() now accept
1187 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1188
Brett Cannonde3b0522006-06-08 17:00:45 +00001189- Buffer objects, at the C level, never used the char buffer
1190 implementation even when the char buffer for the wrapped object was
1191 explicitly requested (originally returned the read or write buffer).
1192 Now a TypeError is raised if the char buffer is not present but is
1193 requested.
1194
Georg Brandlddbaa662006-06-04 21:56:52 +00001195- Patch #1346214: Statements like "if 0: suite" are now again optimized
1196 away like they were in Python 2.4.
1197
Georg Brandlb7c8f542006-05-27 12:30:25 +00001198- Builtin exceptions are now full-blown new-style classes instead of
1199 instances pretending to be classes, which speeds up exception handling
1200 by about 80% in comparison to 2.5a2.
1201
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001202- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1203 Unicode 4.1.
1204
Georg Brandlf4ef1162006-05-26 18:03:31 +00001205- Patch #921466: sys.path_importer_cache is now used to cache valid and
1206 invalid file paths for the built-in import machinery which leads to
1207 fewer open calls on startup.
1208
Tim Peters696cf432006-05-24 21:10:40 +00001209- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1210 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1211 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1212 the number of input digits (it was and remains linear-time for bases
1213 2, 4, 8, 16 and 32).
1214
Tim Petersb713ec22006-05-23 18:45:30 +00001215- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1216 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1217 an integer close to ``sys.maxint``. This was repaired by patch
1218 #1335972, which also gives a nice speedup.
1219
Richard Jonescebbefc2006-05-23 18:28:17 +00001220- Patch #1337051: reduced size of frame objects.
1221
1222- PyErr_NewException now accepts a tuple of base classes as its
1223 "base" parameter.
1224
Richard Jones7c88dcc2006-05-23 10:37:38 +00001225- Patch #876206: function call speedup by retaining allocated frame
1226 objects.
1227
Georg Brandl7b90e162006-05-18 07:01:27 +00001228- Bug #1462152: file() now checks more thoroughly for invalid mode
1229 strings and removes a possible "U" before passing the mode to the
1230 C library function.
1231
Neal Norwitz1004a532006-05-15 07:17:23 +00001232- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1233
Neal Norwitz373f0a72006-05-15 07:04:36 +00001234- Bug #1487966: Fix SystemError with conditional expression in assignment
1235
Martin v. Löwis879768d2006-05-11 13:28:43 +00001236- WindowsError now has two error code attributes: errno, which carries
1237 the error values from errno.h, and winerror, which carries the error
1238 values from winerror.h. Previous versions put the winerror.h values
1239 (from GetLastError()) into the errno attribute.
1240
Martin v. Löwis77736712006-05-04 05:51:03 +00001241- Patch #1475845: Raise IndentationError for unexpected indent.
1242
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001243- Patch #1479181: split open() and file() from being aliases for each other.
1244
Tim Peters44bd9862006-06-01 13:49:23 +00001245- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1246 methods were always silently ignored by dictionaries when comparing keys.
1247 They are now passed through (except when using the C API function
1248 ``PyDict_GetItem()``, whose semantics did not change).
1249
1250- Bug #1456209: In some obscure cases it was possible for a class with a
1251 custom ``__eq__()`` method to confuse dict internals when class instances
1252 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1253 No, you don't have any code that did this ;-)

1256-----------------
1257
Trent Mick960a3f82006-06-28 20:30:41 +00001258- Bug #1295808: expat symbols should be namespaced in pyexpat
1259
1260- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1261
Brett Cannon6ee7d012006-06-08 16:23:04 +00001262- Change binascii.hexlify to accept a read-only buffer instead of only a char
1263 buffer and actually follow its documentation.
1264
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001265- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1266
Nick Coghlanc649ec52006-05-29 12:43:05 +00001267- Patch #1478788 (modified version): The functional extension module has
1268 been renamed to _functools and a functools Python wrapper module added.
1269 This provides a home for additional function related utilities that are
1270 not specifically about functional programming. See PEP 309.
1271
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001272- Patch #1493701: performance enhancements for struct module.
1273
Georg Brandl378d5922006-05-17 14:26:50 +00001274- Patch #1490224: time.altzone is now set correctly on Cygwin.
1275
Georg Brandl8d3342b2006-05-16 07:38:27 +00001276- Patch #1435422: zlib's compress and decompress objects now have a
1277 copy() method.
1278
Andrew MacIntyre92913322006-06-13 15:04:24 +00001279- Patch #1454481: thread stack size is now tunable at runtime for thread
1280 enabled builds on Windows and systems with Posix threads support.
1281
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001282- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1283 (up to the system limit of 32K characters).
1284
1285- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1286 As a result, these functions now raise WindowsError instead of OSError.
1287
Tim Peters7a822da2006-05-25 21:50:17 +00001288- ``time.clock()`` on Win64 should use the high-performance Windows
1289 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1290 Windows platforms).
1291
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001292- Calling Tk_Init twice is refused if the first call failed as that
1293 may deadlock.
1294
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001295- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1296 accept it without potentially using an uninitialized pointer.
1297
1298- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1299 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1300 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001301
Gregory P. Smith372b5832006-06-05 18:48:21 +00001302- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001303 [pybsddb project SF patch number 1466734]
1304
Gregory P. Smith372b5832006-06-05 18:48:21 +00001305- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1306 parameter is supplied. [SF pybsddb bug #1477863]
1307
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001308- bsddb: the __len__ method of a DB object has been fixed to return correct
1309 results. It could previously incorrectly return 0 in some cases.
1310 Fixes SF bug 1493322 (pybsddb bug 1184012).
1311
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001312- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1313 aborts the db transaction safely when a modifier callback fails.
1314 Fixes SF python patch/bug #1408584.
1315
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001316- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001317 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001318 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1319 database calls that would previously deadlock. [SF python bug #775414]
1320
Vinay Sajip28e57612006-07-01 10:45:20 +00001321- Patch #1446489: add support for the ZIP64 extensions to zipfile.

Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001329- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1330 functions.
1331
Martin v. Löwis3798da02006-06-17 18:44:27 +00001332- Patch #812986: Update turtle output even if not tracing.
1333
Vinay Sajip28e57612006-07-01 10:45:20 +00001334- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001335 Tkinter.BaseWidget.
1336
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001337- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1338
Martin v. Löwis337487e2006-06-17 09:15:14 +00001339- Patch #763580: Add name and value arguments to Tkinter variable
1340 classes.
1341
Georg Brandl83cc0d02006-06-14 08:50:03 +00001342- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1343 mime.types file for determining MIME types.
1344
Georg Brandl2605ca82006-06-14 06:08:31 +00001345- Bug #1339007: Shelf objects now don't raise an exception in their
1346 __del__ method when initialization failed.
1347
Martin v. Löwisd8251432006-06-14 05:21:04 +00001348- Patch #1455898: The MBCS codec now supports the incremental mode for
1349 double-byte encodings.
1350
Tim Peters43898b42006-06-14 04:09:25 +00001351- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1352 guarantee that adjacent triples in the return list always describe
1353 non-adjacent blocks. Previously, a pair of matching blocks could end
1354 up being described by multiple adjacent triples that formed a partition
1355 of the matching pair.
1356
Greg Ward0e0c9f42006-06-11 16:24:11 +00001357- Bug #1498146: fix optparse to handle Unicode strings in option help,
1358 description, and epilog.
1359
Greg Wardd1c797e2006-06-11 14:42:41 +00001360- Bug #1366250: minor optparse documentation error.
1361
Greg Ward7f547402006-06-11 00:40:49 +00001362- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1363 clarify docs.
1364
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001365- The wsgiref package has been added to the standard library.
1366
Nick Coghlan676725d2006-06-08 13:54:49 +00001367- The functions update_wrapper() and wraps() have been added to the functools
1368 module. These make it easier to copy relevant metadata from the original
1369 function when writing wrapper functions.
1370
Tim Petersd6a9eef2006-06-05 01:48:21 +00001371- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1372 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001373
Martin v. Löwis3f767792006-06-04 19:36:28 +00001374- Patch #1359618: Speed up charmap encoder by using a trie structure
1375 for lookup.
1376
Tim Petersd609b1a2006-06-02 23:22:51 +00001377- The functions in the ``pprint`` module now sort dictionaries by key
1378 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1379 if and only if its display required more than one line, although that
1380 wasn't documented. The new behavior increases predictability; e.g.,
1381 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1382
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001383- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1384 (thanks for J. J. Lee).
1385
Georg Brandl2b330372006-05-28 20:23:12 +00001386- Patch #1496206: improve urllib2 handling of passwords with respect to
1387 default HTTP and HTTPS ports.
1388
George Yoshidaf3c65de2006-05-28 16:39:09 +00001389- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1390
Bob Ippolito7298f272006-05-23 18:43:47 +00001391- Patch #1281707: speed up gzip.readline.
1392
Georg Brandlb89316f2006-05-17 15:51:16 +00001393- Patch #1180296: Two new functions were added to the locale module:
1394 format_string() to get the effect of "format % items" but locale-aware,
1395 and currency() to format a monetary number with currency sign.
1396
Georg Brandle3a25832006-05-17 14:56:04 +00001397- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1398 and several features added, such as speed and geometry control.
1399
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001400- Patch #1488881: add support for external file objects in bz2 compressed
1401 tarfiles.
1402
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001403- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1404 stdout arguments, making it possible to redirect input and output
1405 for remote debugging.
1406
1407- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1408 a couple of issues, notably handling of long file names using the
1409 GNU LONGNAME extension.
1410
1411- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1412 new flag when ``name`` is already the name of an option flag.
1413
1414- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1415 package.
1416
1417- Patch #1472854: make the rlcompleter.Completer class usable on non-
1418 UNIX platforms.
1419
1420- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1421
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001422- Bug #1472827: correctly escape newlines and tabs in attribute values in
1423 the saxutils.XMLGenerator class.

1455
1456*Release date: 27-APR-2006*
1457
1458Core and builtins
1459-----------------
1460
Thomas Heller1b046642006-04-18 18:51:06 +00001461- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1462 by converting these apis from macros into exported functions again:
1463
1464 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1465 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1466 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1467 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1468 PyRun_String Py_CompileString
1469
Martin v. Löwis45294a92006-04-18 06:24:08 +00001470- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1471
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001472- All uses of PyStructSequence_InitType have been changed to initialize
1473 the type objects only once, even if the interpreter is initialized
1474 multiple times.
1475
Neal Norwitz61546162006-04-14 05:20:28 +00001476- Bug #1454485, array.array('u') could crash the interpreter. This was
1477 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1478 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1479
1480- Py_UNICODE is unsigned. It was always documented as unsigned, but
1481 due to a bug had a signed value in previous versions.
1482
Tim Peters3a5e8b12006-04-11 01:44:07 +00001483- Patch #837242: ``id()`` of any Python object always gives a positive
1484 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1485 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001486 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001487 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001488
Tim Peters3a5e8b12006-04-11 01:44:07 +00001489 def __hash__(self):
1490 return id(self) # WRONG
1491
1492 because a hash result must be a (short) Python int but it was always
1493 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001494 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001495 was always usable as a hash value before this patch. That's no longer
1496 necessarily so.

1498- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001499 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001500 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001501 #1454844)
1502
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001503- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1504 involving generators that have paused outside of any ``try`` or ``with``
1505 blocks. (In 2.5a1, a paused generator that was part of a reference
1506 cycle could not be garbage collected, regardless of whether it was
1507 paused in a ``try`` or ``with`` block.)

1520- Bug #1117761: bsddb.*open() no longer raises an exception when using
1521 the cachesize parameter.
1522
1523- Bug #1149413: bsddb.*open() no longer raises an exception when using
1524 a temporary db (file=None) with the 'n' flag to truncate on open.
1525
1526- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1527 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001528
Armin Rigoa9017c32006-04-19 11:50:27 +00001529- Patch #1062014: AF_UNIX sockets under Linux have a special

1533-------
1534
Peter Astrand7d1d4362006-07-14 14:04:45 +00001535- Bug #1223937: subprocess.CalledProcessError reports the exit status
1536 of the process using the returncode attribute, instead of
1537 abusing errno.
1538
Tim Peters711bf302006-04-25 03:31:36 +00001539- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1540 a doctest to be skipped (the code is not run, and the expected output
1541 or exception is ignored).
1542
Nick Coghlanda2268f2006-04-24 04:37:15 +00001543- Fixed contextlib.nested to cope with exceptions being raised and
1544 caught inside exit handlers.
1545
Greg Wardab05edc2006-04-23 03:47:58 +00001546- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1547 hex, octal, or binary; add ``append_const`` action; keep going if
1548 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1549 added ``epilog`` for better help generation).
1550
Tim Peters21fbd572006-04-21 21:18:10 +00001551- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1552 called from a thread spawned as a side effect of importing a module.
1553
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001554- The pydoc module now supports documenting packages contained in
1555 .zip or .egg files.
1556
1557- The pkgutil module now has several new utility functions, such
1558 as ``walk_packages()`` to support working with packages that are either
1559 in the filesystem or zip files.
1560
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001561- The mailbox module can now modify and delete messages from
1562 mailboxes, in addition to simply reading them. Thanks to Gregory
1563 K. Johnson for writing the code, and to the 2005 Google Summer of
1564 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001565
Tim Petersc7605f22006-04-17 21:12:33 +00001566- The ``__del__`` method of class ``local`` in module ``_threading_local``

Anthony Baxtere29002c2006-04-12 12:07:31 +00001575- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1576 Windows. Bug #1469163.
1577
Phillip J. Eby47032112006-04-11 01:07:43 +00001578- The warnings, linecache, inspect, traceback, site, and doctest modules

1588
Skip Montanaro262fb922006-04-21 02:31:07 +00001589- The pstats.Stats class accepts an optional stream keyword argument to
1590 direct output to an alternate file-like object.
1591
Anthony Baxter51bcb682006-04-05 14:51:42 +00001592Build
1593-----
1594
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001595- The Makefile now has a reindent target, which runs reindent.py on
1596 the library.
1597
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001598- Patch #1470875: Building Python with MS Free Compiler
1599

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001601
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001602- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1603 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001604 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001605 CXX from --with-cxx-main, see description in README.
1606
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001607- Patch #1429775: Link extension modules with the shared libpython.
1608
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001609- Fixed a libffi build problem on MIPS systems.
1610
Tim Peters8931ff12006-05-13 23:28:20 +00001611- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1612 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1613 and "%zu" for unsigned integers of type ``size_t``.
1614
Anthony Baxter51bcb682006-04-05 14:51:42 +00001615Tests
1616-----
1617
Nick Coghlanda2268f2006-04-24 04:37:15 +00001618- test_contextlib now checks contextlib.nested can cope with exceptions
1619 being raised and caught inside exit handlers.
1620
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001621- test_cmd_line now checks operation of the -m and -c command switches
1622
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001623- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1624 it separately and by hand. It also wasn't cleaning up its changes to
1625 the current Decimal context.
1626
Thomas Woutersabd08882006-04-26 15:53:30 +00001627- regrtest.py now has a -M option to run tests that test the new limits of
1628 containers, on 64-bit architectures. Running these tests is only sensible
1629 on 64-bit machines with more than two gigabytes of memory. The argument
1630 passed is the maximum amount of memory for the tests to use.
1631
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001632Tools

1639-------------
1640
Tim Petersb06d28c2006-05-12 01:57:59 +00001641- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1642
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001643- PEP 343: Added Context Types section to the library reference
1644 and attempted to bring other PEP 343 related documentation into
1645 line with the implementation and/or python-dev discussions.
1646
Tim Peters8dc73d22006-04-24 02:03:16 +00001647- Bug #1337990: clarified that ``doctest`` does not support examples
1648 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001651What's New in Python 2.5 alpha 1?
1652=================================
1653
Anthony Baxterebed3f62006-04-03 15:03:44 +00001654*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001655
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001656Core and builtins
1657-----------------
1658
Nick Coghlan43832302006-04-23 17:04:07 +00001659- PEP 338: -m command line switch now delegates to runpy.run_module
1660 allowing it to support modules in packages and zipfiles
1661
Martin v. Löwisc661b882006-04-20 04:54:23 +00001662- On Windows, .DLL is not an accepted file name extension for
1663 extension modules anymore; extensions are only found if they
1664 end in .PYD.
1665
Martin v. Löwisea62d252006-04-03 10:56:49 +00001666- Bug #1421664: sys.stderr.encoding is now set to the same value as
1667 sys.stdout.encoding.
1668
Neal Norwitz92e212f2006-04-03 04:48:37 +00001669- __import__ accepts keyword arguments.
1670
Georg Brandlccadf842006-03-31 18:54:53 +00001671- Patch #1460496: round() now accepts keyword arguments.
1672
Anthony Baxter262c00a2006-03-30 10:53:17 +00001673- Fixed bug #1459029 - unicode reprs were double-escaped.
1674
Hye-Shik Changd478f342006-03-23 12:32:36 +00001675- Patch #1396919: The system scope threads are reenabled on FreeBSD
1676 5.4 and later versions.
1677
Neal Norwitze98ccf62006-03-23 05:39:47 +00001678- Bug #1115379: Compiling a Unicode string with an encoding declaration
1679 now gives a SyntaxError.
1680
Georg Brandlabd1ff82006-03-18 07:59:59 +00001681- Previously, Python code had no easy way to access the contents of a
1682 cell object. Now, a ``cell_contents`` attribute has been added
1683 (closes patch #1170323).
1684
Tim Peterscf79aac2006-03-16 01:14:46 +00001685- Patch #1123430: Python's small-object allocator now returns an arena to
1686 the system ``free()`` when all memory within an arena becomes unused
1687 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1688 freed. Some applications will see a drop in virtual memory size now,
1689 especially long-running applications that, from time to time, temporarily
1690 use a large number of small objects. Note that when Python returns an
1691 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001692 platform C library will in turn return that memory to the operating system.
1693 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001694 appears to be effective at least on Microsoft C and gcc-based systems.
1695 Thanks to Evan Jones for hard work and patience.
1696
Georg Brandl533ff6f2006-03-08 18:09:27 +00001697- Patch #1434038: property() now uses the getter's docstring if there is
1698 no "doc" argument given. This makes it possible to legitimately use
1699 property() as a decorator to produce a read-only property.
1700
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001701- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1702 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1703 of requiring an int or long in slicing and a few other contexts, enabling
1704 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1705
Neal Norwitz995acdf2006-03-07 05:01:00 +00001706- Fixed various bugs reported by Coverity's Prevent tool.
1707
Brett Cannonbf364092006-03-01 04:25:17 +00001708- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1709 new exception base class, BaseException, which has a new message attribute.
1710 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1711 Raising a string exception now raises a DeprecationWarning.
1712
Thomas Woutersfb609f42006-02-28 16:37:25 +00001713- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1714 explicitly relative, using 'from .module import name' to mean 'from the same
1715 package as this module is in. Imports without dots still default to the
1716 old relative-then-absolute, unless 'from __future__ import
1717 absolute_import' is used.
1718
Brett Cannona7446e32006-02-27 23:39:10 +00001719- Properly check if 'warnings' raises an exception (usually when a filter set
1720 to "error" is triggered) when raising a warning for raising string
1721 exceptions.
1722
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001723- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001724 The name was removed from Include/code.h.
1725
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001726- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001727
Guido van Rossum1968ad32006-02-25 22:38:04 +00001728- Patch 1433928:
1729 - The copy module now "copies" function objects (as atomic objects).
1730 - dict.__getitem__ now looks for a __missing__ hook before raising
1731 KeyError.
1732
Tim Peters84ef21c2006-02-28 20:39:06 +00001733- PEP 343: with statement implemented. Needs ``from __future__ import
1734 with_statement``. Use of 'with' as a variable will generate a warning.
1735 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001736 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001737 The following objects have __context__ methods:
1738 - The built-in file type.
1739 - The thread.LockType type.
1740 - The following types defined by the threading module:
1741 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1742 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001743
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001744- Fix the encodings package codec search function to only search
1745 inside its own package. Fixes problem reported in patch #1433198.
1746
1747 Note: Codec packages should implement and register their own
1748 codec search function. PEP 100 has the details.
1749
Tim Peters9ea89d22006-06-04 03:26:02 +00001750- PEP 353: Using ``Py_ssize_t`` as the index type.
1751
1752- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1753 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1754 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1755 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1756 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001757
Neal Norwitzfc76d632006-01-10 06:03:13 +00001758- Patch #1400181, fix unicode string formatting to not use the locale.
1759 This is how string objects work. u'%f' could use , instead of .
1760 for the decimal point. Now both strings and unicode always use periods.
1761
Neal Norwitz671b9e32006-01-09 07:07:12 +00001762- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1763 configure would break checking curses.h.
1764
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001765- Bug #959576: The pwd module is now builtin. This allows Python to be
1766 built on UNIX platforms without $HOME set.
1767
Neal Norwitzc10978f2005-12-19 06:07:16 +00001768- Bug #1072182, fix some potential problems if characters are signed.
1769
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001770- Bug #889500, fix line number on SyntaxWarning for global declarations.
1771
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001772- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1773
Neal Norwitze7214a12005-12-18 05:03:17 +00001774- Support for converting hex strings to floats no longer works.
1775 This was not portable. float('0x3') now raises a ValueError.
1776
Barry Warsaw2a38a862005-12-18 01:27:35 +00001777- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001778 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001779 is now displayed in interactive prompt banner.
1780
Georg Brandlfa166682005-12-17 21:45:17 +00001781- Implementation of PEP 341 - Unification of try/except and try/finally.
1782 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001783 one try statement instead of two nested ones. Patch #1355913.

Hye-Shik Chang835b2432005-12-17 04:38:31 +00001785- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1786 now encodes backslash correctly.
1787
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001788- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1789
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001790- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001791 and long longs.
1792
Neal Norwitz67715f02005-11-09 06:59:35 +00001793- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001794 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001795 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001796
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001797- Replaced most Unicode charmap codecs with new ones using the
1798 new Unicode translate string feature in the builtin charmap
1799 codec; the codecs were created from the mapping tables available
1800 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1801 encodings now include a mapping for the Apple logo)
1802
Tim Peterse3547fd2005-12-16 23:13:57 +00001803- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001804
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001805- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001806
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001807- A new AST parser implementation was completed. The abstract
1808 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001809 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001810
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001811- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001812 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1813
Neal Norwitz708e51a2005-10-03 04:48:15 +00001814- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1815
Neal Norwitz11bd1192005-10-03 00:54:56 +00001816- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1817 Provide a warning when a directory is passed on the command line.
1818
Neal Norwitz40d37812005-10-02 01:48:49 +00001819- Fix segfault with invalid coding.
1820
1821- SF bug #772896: unknown encoding results in MemoryError.
1822
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001823- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001824 supported a __len__() method which evaluated to False when the iterator
1825 was empty.
1826
Guido van Rossum630db602005-09-20 18:49:54 +00001827- On 64-bit platforms, when __len__() returns a value that cannot be
1828 represented as a C int, raise OverflowError.
1829
Skip Montanarof8948ca2005-09-19 03:54:46 +00001830- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001831 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001832
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001833- SF bug #893549: parsing keyword arguments was broken with a few format
1834 codes.
1835
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001836- Changes donated by Elemental Security to make it work on AIX 5.3
1837 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1838 bug #105470: test_pwd fails on 64bit system (Opteron).
1839
Guido van Rossum539c6622005-09-14 17:49:54 +00001840- Changes donated by Elemental Security to make it work on HP-UX 11 on
1841 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1842
Georg Brandl4550b8d2005-08-26 06:43:52 +00001843- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001844 (fixes bug #1119418).
1845
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001846- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1847
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001848- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1849 exceptions that cause a function to exit.
1850
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001851- The implementation of set() and frozenset() was revised to use its
1852 own internal data structure. Memory consumption is reduced by 1/3
1853 and there are modest speed-ups as well. The API is unchanged.
1854
Tim Petersde7990b2005-07-17 23:45:23 +00001855- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1856
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001857- SF bug #1229429: PyObject_CallMethod failed to decrement some
1858 reference counts in some error exit cases.
1859
Tim Petersecc6e6a2005-07-10 22:30:55 +00001860- SF bug #1185883: Python's small-object memory allocator took over
1861 a block managed by the platform C library whenever a realloc specified
1862 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001863 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001864 portable way to copy data from the C-managed block into Python's
1865 small-object space without risking a memory fault. Python's small-object
1866 realloc now leaves such blocks under the control of the platform C
1867 realloc.
1868
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001869- SF bug #1232517: An overflow error was not detected properly when
1870 attempting to convert a large float to an int in os.utime().
1871
Raymond Hettinger3296e692005-06-29 23:29:56 +00001872- SF bug #1224347: hex longs now print with lowercase letters just
1873 like their int counterparts.
1874
Michael W. Hudson188d4362005-06-20 16:52:57 +00001875- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1876 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1877 interpreter states; back out that fix and do a better job (see
1878 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1879 for a longer write-up of the problem).
1880
Michael W. Hudsondf888462005-06-03 14:41:55 +00001881- SF patch #1180995: marshal now uses a binary format by default when
1882 serializing floats.
1883
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001884- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1885 the routines that promise to produce IEEE 754 binary representations
1886 of floats now simply copy bytes around.
1887
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001888- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1889 278.
1890
Brett Cannonc3647ac2005-04-26 03:45:26 +00001891- patch #1109424: int, long, float, complex, and unicode now check for the
1892 proper magic slot for type conversions when subclassed. Previously the
1893 magic slot was ignored during conversion. Semantics now match the way
1894 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001895 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001896 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001897 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001898
Barry Warsawc8d907c2005-04-19 23:43:40 +00001899- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1900 NULL, now raise an AttributeError when attempting to set or delete the
1901 attribute. Previously a TypeError was raised, but this was inconsistent
1902 with the equivalent pure-Python implementation.
1903
Michael W. Hudson774479c2005-04-18 08:46:17 +00001904- It is now safe to call PyGILState_Release() before
1905 PyEval_InitThreads() (note that if there is reason to believe there
1906 are multiple threads around you still must call PyEval_InitThreads()
1907 before using the Python API; this fix is for extension modules that
1908 have no way of knowing if Python is multi-threaded yet).
1909
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001910- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1911 disabled caused a crash.
1912
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001913- Bug #1165306: instancemethod_new allowed the creation of a method
1914 with im_class == im_self == NULL, which caused a crash when called.
1915
Tim Petersecc6e6a2005-07-10 22:30:55 +00001916- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001917 fixes the crash seen in bug #1165761
1918
Raymond Hettinger96229b12005-03-11 06:49:40 +00001919- Added two new builtins, any() and all().
1920
Brett Cannon409d8f22005-03-05 06:47:57 +00001921- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001922 (e.g., ``class C(): pass`` is no longer a syntax error).
1923 Patch #1176012 added support to the 'parser' module and 'compiler' package
1924 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001925
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001926- Patch #1115086: Support PY_LONGLONG in structmember.
1927
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001928- Bug #1155938: new style classes did not check that __init__() was
1929 returning None.
1930
Tim Petersecc6e6a2005-07-10 22:30:55 +00001931- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001932 ('\') with a specific error message.
1933
Martin v. Löwisff232d72005-03-03 09:24:38 +00001934- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1935
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001936- Bug #1124295: the __name__ attribute of file objects was
1937 inadvertently made inaccessible in restricted mode.
1938
Tim Petersecc6e6a2005-07-10 22:30:55 +00001939- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001940 an ferror() call.
1941
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001942- min() and max() now support key= arguments with the same meaning as in
1943 list.sort().
1944
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001945- The peephole optimizer now performs simple constant folding in expressions:
1946 (2+3) --> (5).
1947
Raymond Hettingera422c342005-01-11 03:03:27 +00001948- set and frozenset objects can now be marshalled. SF #1098985.
1949
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001950- Bug #1077106: Poor argument checking could cause memory corruption
1951 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001952
Jeremy Hyltonab630502005-02-04 18:44:06 +00001953- The parser did not complain about future statements in illegal
1954 positions. It once again reports a syntax error if a future
1955 statement occurs after anything other than a doc string.
1956
Neil Schemenauercf52c072005-08-12 17:34:58 +00001957- Change the %s format specifier for str objects so that it returns a
1958 unicode instance if the argument is not an instance of basestring and
1959 calling __str__ on the argument returns a unicode instance.
1960
Tim Petersf4e69282006-02-27 17:15:31 +00001961- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1962 current thread state when the auto-GIL-state machinery knows about
1963 it (since the thread state is being deleted, continuing to remember it
1964 can't help, but can hurt if another thread happens to get created with
1965 the same thread id).
1966
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001967Extension Modules
1968-----------------
1969

Georg Brandlbc45a3f2006-03-17 19:17:34 +00001979
Neal Norwitz10be10c2006-03-16 06:50:13 +00001980- Everything under lib-old was removed. This includes the following modules:
1981 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00001982 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001983 util, whatsound, whrandom, zmod
1984
1985- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1986
1987- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001988 is deprecated. The undocumented re.engine variable no longer exists.
1989
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001990- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1991 SS2 (single-shift 2) escape sequences correctly.
1992
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001993- The unicodedata module was updated to the 4.1 version of the Unicode
1994 database. The 3.2 version is still available as unicodedata.db_3_2_0
1995 for applications that require this specific version (such as IDNA).
1996
Neal Norwitzb62c4332006-03-04 18:35:47 +00001997- The timing module is no longer built by default. It was deprecated
1998 in PEP 4 in Python 2.0 or earlier.
1999
Guido van Rossum1968ad32006-02-25 22:38:04 +00002000- Patch 1433928: Added a new type, defaultdict, to the collections module.
2001 This uses the new __missing__ hook behavior added to dict (see above).
2002
Georg Brandldbd83392006-02-20 09:42:33 +00002003- Bug #854823: socketmodule now builds on Sun platforms even when
2004 INET_ADDRSTRLEN is not defined.
2005
Georg Brandlf4f44152006-02-18 22:29:33 +00002006- Patch #1393157: os.startfile() now has an optional argument to specify
2007 a "command verb" to invoke on the file.
2008
Neal Norwitz082b2df2006-02-07 07:04:46 +00002009- Bug #876637, prevent stack corruption when socket descriptor
2010 is larger than FD_SETSIZE.
2011
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00002012- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
2013 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
2014 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
2015
Martin v. Löwis57a34e82006-02-04 19:12:37 +00002016- Patch #1422385: The nis module now supports access to domains other
2017 than the system default domain.
2018
Martin v. Löwis14694662006-02-03 12:54:16 +00002019- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2020 are reported, the limit on path name lengths is removed, and stat reports
2021 WindowsError now (instead of OSError).
2022
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002023- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

2033 Also fix ungetmouse() which did not accept arguments properly.
2034 The code now conforms to the documented signature.
2035
Neal Norwitz5e3d8622006-01-09 06:24:35 +00002036- Bug #1400115, Fix segfault when calling curses.panel.userptr()
2037 without prior setting of the userptr.
2038

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002157- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2158 been renamed to have only a single underscore prefix. This was done to
2159 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002160
Nick Coghlan43832302006-04-23 17:04:07 +00002161- PEP 338: new module runpy defines a run_module function to support
2162 executing modules which provide access to source code or a code object
2163 via the PEP 302 import mechanisms.
2164
Anthony Baxter93f5b932006-04-03 08:05:07 +00002165- The email module's parsedate_tz function now sets the daylight savings

2173 in attribute values.
2174
Anthony Baxterc51ee692006-04-01 00:57:31 +00002175- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002176 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002177 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002178 module will not be built.
2179
Tim Petersc17976e2006-04-01 00:26:53 +00002180- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2181 aren't officially supported here, and trying to use them will probably
2182 raise an exception some day. But dicts have been allowed, and "mostly
2183 worked", so support for them won't go away without warning.
2184
Georg Brandl338ef7d2006-03-31 18:42:16 +00002185- Bug #1445068: getpass.getpass() can now be given an explicit stream
2186 argument to specify where to write the prompt.
2187

2197 to make it easier to monitor when daemon threads have completed
2198 processing all enqueued tasks. Patch #1455676.
2199

2203
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002204- email 4.0 package now integrated. This is largely the same as the email 3.0
2205 package that was included in Python 2.3, except that PEP 8 module names are
2206 now used (e.g. mail.message instead of email.Message). The MIME classes
2207 have been moved to a subpackage (e.g. email.mime.text instead of
2208 email.MIMEText). The old names are still supported for now. Several
2209 deprecated Message methods have been removed and lots of bugs have been
2210 fixed. More details can be found in the email package documentation.
2211
Walter Dörwald40108c92006-03-27 08:15:44 +00002212- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2213 (a subclass of tuple) that provides incremental decoders and encoders
2214 (a way to use stateful codecs without the stream API). Python functions
2215 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2216 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2217 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002218
Walter Dörwald067db482006-03-15 22:17:27 +00002219- Patch #1359365: Calling next() on a closed StringIO.String object raises
2220 a ValueError instead of a StopIteration now (like file and cString.String do).
2221 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2222 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002223
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002224- A regrtest option -w was added to re-run failed tests in verbose mode.

Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002235- PEP 343: new module contextlib.py defines decorator @contextmanager
2236 and helpful context managers nested() and closing().
2237

Martin v. Löwis3e865952006-01-24 15:51:21 +00002272 specifications, raises IOErrors when proxies for unsupported protocols
2273 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00002296 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2297 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2298 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2299 Ronald L. Rivest offered this advice for Python:
2300
2301 "The consensus of researchers in this area (at least as
2302 expressed at the NIST Hash Function Workshop 10/31/05),
2303 is that SHA-256 is a good choice for the time being, but
2304 that research should continue, and other alternatives may
2305 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002306
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002307- Added a subset of Fredrik Lundh's ElementTree package. Available

2360 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002361 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002362

2382
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00002383- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
2384 to W3C name (404 -> 'Not Found'). RFE #1216944.
2385
Georg Brandl9e43acf2005-07-04 17:16:07 +00002386- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2387 as this can cause problems with apps closing all file descriptors.

2400 Bug #1224621.
2401
Raymond Hettinger68c04532005-06-10 11:05:19 +00002402- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002403 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002404 the generate_tokens() function now accepts a callable argument that
2405 terminates by raising StopIteration.
2406
Georg Brandl9166e1a2005-06-04 09:20:03 +00002407- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2408
Georg Brandl268e61c2005-06-03 14:28:50 +00002409- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first

2411
Skip Montanaro174dd222005-05-14 20:54:16 +00002412- Patch #1120353: The xmlrpclib module provides better, more transparent,

2414 to True, applications shouldn't have to fiddle with the DateTime wrapper
2415 class at all.
2416
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002417- distutils.commands.upload was added to support uploading distribution
2418 files to PyPI.
2419
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002420- distutils.commands.register now encodes the data as UTF-8 before posting
2421 them to PyPI.
2422
Raymond Hettinger267b8682005-03-27 10:47:39 +00002423- decimal operator and comparison methods now return NotImplemented
2424 instead of raising a TypeError when interacting with other types. This
2425 allows other classes to implement __radd__ style methods and have them
2426 work as expected.
2427
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002428- Bug #1163325: Decimal infinities failed to hash. Attempting to
2429 hash a NaN raised an InvalidOperation instead of a TypeError.
2430
Tim Petersecc6e6a2005-07-10 22:30:55 +00002431- Patch #918101: Add tarfile open mode r|* for auto-detection of the

2465
Guido van Rossumd0641422005-02-03 15:01:24 +00002466- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2467 disables recursive traversal through instance attributes, which can
2468 be exploited in various ways.
2469
Tim Peterse3547fd2005-12-16 23:13:57 +00002470- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002471 flags on the HTTP listening socket.
2472
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002473- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2474 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2475
Fred Drakefbdeaad2006-07-29 16:56:15 +00002476- Patches #893642, #1039083: add allow_none, encoding arguments to
2477 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002478
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002479- Bug #1110478: Revert os.environ.update to do putenv again.
2480
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002481- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2482
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002483- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2484
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002485- Enhancements to the csv module:
2486
2487 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002488 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002489 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002490 + Dialect parameter parsing has been re-implemented to improve error
2491 reporting.
2492 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2493 dictates.
2494 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002495 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002496 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002497 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2498 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002499 + reader now allows \r characters to be quoted (previously it only allowed
2500 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002501 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002502 + Dialect classes passed to the module are no longer instantiated by
2503 the module before being parsed (the former validation scheme required
2504 this, but the mechanism was unreliable).
2505 + The dialect registry now contains instances of the internal
2506 C-coded dialect type, rather than references to python objects.
2507 + the internal c-coded dialect type is now immutable.
2508 + register_dialect now accepts the same keyword dialect specifications
2509 as the reader and writer, allowing the user to register dialects
2510 without first creating a dialect class.
2511 + a configurable limit to the size of parsed fields has been added -
2512 previously, an unmatched quote character could result in the entire
2513 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002514 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002515 the parser field size limit (returning the former limit). The initial
2516 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002517 + A line_num attribute has been added to the reader object, which tracks
2518 the number of lines read from the source iterator. This is not
2519 the same as the number of records returned, as records can span
2520 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002521 + reader and writer objects were not being registered with the cyclic-GC.
2522 This has been fixed.
2523
Brett Cannone6539c42005-01-08 02:43:53 +00002524- _DummyThread objects in the threading module now delete self.__block that is
2525 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2526 lock primitives tend to be limited in number and thus should not be wasted on
2527 a _DummyThread object. Fixes bug #1089632.
2528
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002529- The imghdr module now detects Exif files.
2530
Raymond Hettinger6065d322004-12-20 23:51:53 +00002531- StringIO.truncate() now correctly adjusts the size attribute.
2532 (Bug #951915).
2533
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002534- locale.py now uses an updated locale alias table (built using
2535 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2536 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002537 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002538
Raymond Hettinger3557f422004-12-07 12:02:02 +00002539- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2540
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002541- the pickle module no longer accepts the deprecated None option in the
2542 args tuple returned by __reduce__().
2543
Brett Cannon84667c02004-12-07 03:25:18 +00002544- optparse now optionally imports gettext. This allows its use in setup.py.
2545
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002546- the pickle module no longer uses the deprecated bin parameter.
2547
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002548- the shelve module no longer uses the deprecated binary parameter.
2549
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002550- the pstats module no longer uses the deprecated ignore() method.
2551
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002552- the filecmp module no longer uses the deprecated use_statcache argument.
2553
Raymond Hettinger664347b2004-12-04 21:21:53 +00002554- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2555 extended or overridden by subclasses. Formerly, the subclassed method would
2556 be ignored by the rest of the module. (Bug #1078905).
2557
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002558- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002559 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002560
Walter Dörwald36733692004-12-22 12:50:50 +00002561- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2562 once when a size argument is given. This prevents a buffer overflow in the
2563 tokenizer with very long source lines.
2564
Barry Warsaw538561e2006-01-01 21:48:54 +00002565- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2566 immediately after creating the object, without any intervening
2567 ``.decompress()`` calls.

Skip Montanaro05885812005-01-16 20:48:27 +00002569- The reconvert.quote function can now emit triple-quoted strings. The
2570 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002571
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002572- ``UserString.MutableString`` now supports negative indices in
2573 ``__setitem__`` and ``__delitem__``
2574
Greg Ward40407942005-03-05 02:53:17 +00002575- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2576 correctly.
2577
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002578- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2579 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2580 character even if the user has passed a size parameter to get a proper
2581 line ending. Remove the special handling of a "\r\n" that has been split
2582 between two lines.
2583
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002584- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2585 about illegal code points. The codec now supports PEP 293 style error
2586 handlers.
2587
Walter Dörwald78a78b02005-09-01 12:04:29 +00002588- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002589 from the input stream, so that the output is a byte string in the correct
2590 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002591
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002592- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2593 considering it exactly like a '*'.
2594
Walter Dörwald007f8df2005-10-09 19:42:27 +00002595- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2596 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002597
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002598- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2599
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002600- Patch #1413711: Certain patterns of differences were making difflib
2601 touch the recursion limit.
2602
Walter Dörwald58917a62006-03-31 15:26:22 +00002603- Bug #947906: An object oriented interface has been added to the calendar
2604 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002605 called as a script (e.g. via ``python -mcalendar``). Localized month and
2606 weekday names can be ouput (even if an exotic encoding is used) using
2607 special classes that use unicode.

2610-----
2611
Neal Norwitz602d3392006-03-31 08:21:40 +00002612- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2613 by using -mieee gcc option.
2614

2616
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002617- Build support for Win64-AMD64 was added.
2618
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002619- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2620
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002621- Patch #881820: look for openpty and forkpty also in libbsd.
2622
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002623- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2624 The zlib module is now builtin on Windows.
2625
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002626- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2627
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002628- Bug #1189330: configure did not correctly determine the necessary
2629 value of LINKCC if python was built with GCC 4.0.
2630
Trent Mick8321b422005-07-26 02:29:21 +00002631- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2632 vulnerability in zlib 1.2.1 and 1.2.2.
2633
Brett Cannon08cd5982005-04-24 22:26:38 +00002634- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2635 flags that change binary compatibility. Changes were also made to
2636 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002637 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002638
Bob Ippolitoed233462005-03-29 13:47:59 +00002639- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2640 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2641 no longer exists). This configure patch makes things right.
2642
Martin v. Löwise2713be2005-03-08 15:03:08 +00002643- Bug #1158607: Build with --disable-unicode again.
2644
Brett Cannon46d96232005-02-16 00:07:19 +00002645- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2646 defined. Discovered as a result of not being able to build on OS X.
2647
Brett Cannon516592f2004-12-07 00:42:59 +00002648- setup.py now uses the directories specified in LDFLAGS using the -L option
2649 and in CPPFLAGS using the -I option for adding library and include
2650 directories, respectively, for compiling extension modules against. This has
2651 led to the core being compiled using the values in CPPFLAGS. It also removes
2652 the need for the special-casing of both DarwinPorts and Fink for darwin since
2653 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2654 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2655 Fink, ``-I/opt/local/include`` for DarwinPorts).
2656
Brett Cannon43802422005-02-10 20:48:03 +00002657- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2658 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2659 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2660 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002662C API
2663-----
2664
Tim Petersc9d78aa2006-03-26 23:27:58 +00002665- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2666 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2667 is obtained via the ``PyObject_`` family, it must be released via the
2668 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2669 always been officially true, but when Python's small-object allocator was
2670 introduced, an attempt was made to cater to a few extension modules
2671 discovered at the time that obtained memory via ``PyObject_New`` but
2672 released it via ``PyMem_DEL``. It's years later, and if such code still
2673 exists it will fail now (probably with segfaults, but calling wrong
2674 low-level memory management functions can yield many symptoms).
2675
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002676- Added a C API for set and frozenset objects.
2677
Raymond Hettinger66517482004-12-03 11:45:13 +00002678- Removed PyRange_New().
2679
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002680- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2681 mapping argument now. This string is used as a mapping table. Byte values
2682 greater than the length of the string and 0xFFFE are treated as undefined
2683 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00002689- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002690
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002691- Patch #1276356: New resource "urlfetch" is implemented. This enables
2692 even impatient people to run tests that require remote files.
