Georg Brandl2c94bf72006-09-24 10:36:01 +0000347- Make webbrowser.BackgroundBrowser usable in Windows (it wasn't because

Guido van Rossumc69ac252006-08-10 18:09:25 +0000557What's New in Python 2.5 release candidate 1?
558=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000559
Anthony Baxterb4096662006-08-16 03:42:26 +0000560*Release date: 17-AUG-2006*

562Core and builtins
563-----------------
564
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000565- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000566 compared equal or unequal to a string and a UnicodeDecodeError
567 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000568
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000569 Instead, the equal (==) and unequal (!=) comparison operators will
570 now issue a UnicodeWarning and interpret the two objects as
571 unequal. The UnicodeWarning can be filtered as desired using
572 the warning framework, e.g. silenced completely, turned into an
573 exception, logged, etc.
574
575 Note that compare operators other than equal and unequal will still
576 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000577
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000578- Fix segfault when doing string formatting on subclasses of long.

584 classic classes.
585
586- Patch #1538606, Fix __index__() clipping. There were some problems
587 discovered with the API and how integers that didn't fit into Py_ssize_t
588 were handled. This patch attempts to provide enough alternatives
589 to effectively use __index__.
590
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000591- Bug #1536021: __hash__ may now return long int; the final hash
592 value is obtained by invoking hash on the long int.
593

Neal Norwitz4ffedad2006-08-04 04:58:47 +0000602- Bug #1191458: tracing over for loops now produces a line event
603 on each iteration. Fixing this problem required changing the .pyc
604 magic number. This means that .pyc files generated before 2.5c1
605 will be regenerated.
606
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000607- Bug #1333982: string/number constants were inappropriately stored
608 in the byte code and co_consts even if they were not used, ie
609 immediately popped off the stack.
610
Georg Brandle9462c72006-08-04 18:03:37 +0000611- Fixed a reference-counting problem in property().

615-------
616
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000617- Fix a bug in the ``compiler`` package that caused invalid code to be
618 generated for generator expressions.
619
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000620- The distutils version has been changed to 2.5.0. The change to
621 keep it programmatically in sync with the Python version running
622 the code (introduced in 2.5b3) has been reverted. It will continue
623 to be maintained manually as static string literal.
624
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000625- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000626 and this cannot be converted to the required C type, an exception is
627 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000628 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000629
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000630- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000631 an exception.
632
Tim Petersc10c9d02006-09-05 02:18:09 +0000633- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000634 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000635 workarounds for clocks with low resolution, to stop the code yielding
636 duplicate UUIDs.
637
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000638- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
639 before raising SystemExit, allowing IDLE to honor quit() and exit().
640
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000641- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
642
Georg Brandl7a1af772006-08-14 21:55:28 +0000643- Patch #1536071: trace.py should now find the full module name of a
644 file correctly even on Windows.
645
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000646- logging's atexit hook now runs even if the rest of the module has
647 already been cleaned up.
648
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000649- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000650
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000651- Bug #1531405, format_exception no longer raises an exception if
652 str(exception) raised an exception.
653
Neil Schemenauer06ded092006-08-04 16:20:30 +0000654- Fix a bug in the ``compiler`` package that caused invalid code to be
655 generated for nested functions.

Georg Brandl3335a7a2006-08-14 21:42:55 +0000663- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
664 raises the correct exceptions.
665
Thomas Heller1ce433e2006-08-14 16:20:04 +0000666- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
667 '-no-stack-protector' compiler flag for OpenBSD has been removed.
668
Thomas Heller86720042006-08-14 11:17:48 +0000669- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
670 uses the _as_parameter_ attribute when objects are passed to foreign
671 function calls. The ctypes version number was changed to 1.0.1.
672
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000673- Bug #1530559, struct.pack raises TypeError where it used to convert.
674 Passing float arguments to struct.pack when integers are expected
675 now triggers a DeprecationWarning.

Martin v. Löwisa09fd6e2006-08-16 12:55:10 +0000701- Bug #1535502, build _hashlib on Windows, and use masm assembler
702 code in OpenSSL.
703
Thomas Hellerdb7b4432006-08-04 19:49:31 +0000704- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

710-----
711
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000712- New API for Unicode rich comparisons: PyUnicode_RichCompare()
713
Tim Peters4643c2f2006-08-10 22:45:34 +0000714- Bug #1069160. Internal correctness changes were made to
715 ``PyThreadState_SetAsyncExc()``. A test case was added, and
716 the documentation was changed to state that the return value
717 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +0000720What's New in Python 2.5 beta 3?
721================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000722
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000723*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000724
725Core and builtins
726-----------------
727
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000728- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000729 returned a long (see PEP 353).
730
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000731- Bug #1515471: string.replace() accepts character buffers again.
732
Neal Norwitz07aadb12006-07-30 06:55:48 +0000733- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
734 This provides the proper warning for struct.pack().
735 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
736
Neal Norwitz0d62a062006-07-30 06:53:31 +0000737- Patch #1531113: Fix augmented assignment with yield expressions.
738 Also fix a SystemError when trying to assign to yield expressions.
739
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000740- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
741 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
742 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
743 excessive filesystem operations during imports.
744
Tim Petersbc24eee2006-07-27 01:14:53 +0000745- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
746 operations on signed longs that are formally undefined by C.
747 Unfortunately, at least one compiler now cares about that, so complicated
748 the code to make that compiler happy again.
749
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000750- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
751
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000752- Patch #1232023: Stop including current directory in search
753 path on Windows.
754
Neal Norwitze1fdb322006-07-21 05:32:28 +0000755- Fix some potential crashes found with failmalloc.
756
Neal Norwitze7563102006-07-17 01:00:16 +0000757- Fix warnings reported by Klocwork's static analysis tool.
758
Neal Norwitz84be93b2006-07-16 01:50:38 +0000759- Bug #1512814, Fix incorrect lineno's when code within a function
760 had more than 255 blank lines.
761
Georg Brandl9dceedb2006-07-12 15:31:17 +0000762- Patch #1521179: Python now accepts the standard options ``--help`` and
763 ``--version`` as well as ``/?`` on Windows.
764
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000765- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000766 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000767 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000768
Tim Peters112aad32006-07-19 00:03:19 +0000769- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000770 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000771 new ``sys._current_frames()`` returns a dictionary with one entry,
772 mapping the faux "thread id" 0 to the current frame.
773
Ronald Oussoren3075e162006-07-25 20:28:55 +0000774- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000775

Neal Norwitza1f10902006-07-12 07:28:29 +0000777Library
778-------
779
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000780- Correction of patch #1455898: In the mbcs decoder, set final=False
781 for stream decoder, but final=True for the decode function.
782
Georg Brandl07fec3a2006-08-01 18:49:24 +0000783- os.urandom no longer masks unrelated exceptions like SystemExit or
784 KeyboardInterrupt.
785
Tim Peters4643c2f2006-08-10 22:45:34 +0000786- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000787 shutil.copytree on Windows
788
Georg Brandle34ac7c2006-07-30 11:07:23 +0000789- Bug #1002398: The documentation for os.path.sameopenfile now correctly
790 refers to file descriptors, not file objects.
791
Tim Petersc10c9d02006-09-05 02:18:09 +0000792- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000793 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000794 #1513611, and probably others.
795
Georg Brandledd9b0d2006-07-29 09:33:26 +0000796- Bug #1441397: The compiler module now recognizes module and function
797 docstrings correctly as it did in Python 2.4.
798
Tim Peters6f681472006-07-27 23:44:37 +0000799- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
800 lost that tests are sorted by name before being run. This rarely
801 matters for well-written tests, but can create baffling symptoms if
802 side effects from one test to the next affect outcomes. ``DocTestFinder``
803 has been changed to sort the list of tests it returns.
804
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000805- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000806 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000807
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000808- Bug #978833: Really close underlying socket in _socketobject.close.
809
Georg Brandl8c036cc2006-08-20 13:15:39 +0000810- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
811 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000812
Georg Brandlcf0c1722006-07-26 07:23:32 +0000813- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
814 to recursive calls and call it with the failing package name.
815
Martin v. Löwis0b483032006-07-25 09:53:12 +0000816- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
817
Georg Brandlc13c34c2006-07-24 14:09:56 +0000818- Patch #1515343: Fix printing of deprecated string exceptions with a
819 value in the traceback module.
820
Greg Ward48fae7a2006-07-23 16:05:51 +0000821- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
822
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000823- Patch #1524429: Use repr() instead of backticks in Tkinter again.
824
Brett Cannoncaebe222006-07-18 04:41:36 +0000825- Bug #1520914: Change time.strftime() to accept a zero for any position in its
826 argument tuple. For arguments where zero is illegal, the value is forced to
827 the minimum value that is correct. This is to support an undocumented but
828 common way people used to fill in inconsequential information in the time
829 tuple pre-2.4.
830
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000831- Patch #1220874: Update the binhex module for Mach-O.
832
Barry Warsawb110bad2006-07-21 14:51:07 +0000833- The email package has improved RFC 2231 support, specifically for
834 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
835 (name*0=<blah>) parameter continuations. This may change the types of
836 values returned from email.message.Message.get_param() and friends.
837 Specifically in some cases where non-encoded continuations were used,
838 get_param() used to return a 3-tuple of (None, None, string) whereas now it
839 will just return the string (since non-encoded continuations don't have
840 charset and language parts).
841
842 Also, whereas % values were decoded in all parameter continuations, they are
843 now only decoded in encoded parameter parts.
844
Ronald Oussoren3075e162006-07-25 20:28:55 +0000845- Bug #1517990: IDLE keybindings on MacOS X now work correctly
846
847- Bug #1517996: IDLE now longer shows the default Tk menu when a
848 path browser, class browser or debugger is the frontmost window on MacOS X
849
Barry Warsaw00decd72006-07-27 23:43:15 +0000850- Patch #1520294: Support for getset and member descriptors in types.py,
851 inspect.py, and pydoc.py. Specifically, this allows for querying the type
852 of an object against these built-in types and more importantly, for getting
853 their docstrings printed in the interactive interpreter's help() function.

857-----------------
858
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000859- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
860 a socket operation on a socket with a timeout, the exception will be
861 caught correctly. Previously, the exception was not caught.
862
Thomas Heller1393d6a2006-07-28 21:43:20 +0000863- Patch #1529514: The _ctypes extension is now compiled on more
864 openbsd target platforms.
865
Tim Peters9cab5932006-07-28 00:30:00 +0000866- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
867 a memory leak, affecting pickles and deep copies.
868
Tim Petersbc24eee2006-07-27 01:14:53 +0000869- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000870 Paul Eggert.
871
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000872- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
873
Thomas Hellerce049a02006-07-14 17:51:14 +0000874- Patch #1521817: Index range checking on ctypes arrays containing
875 exactly one element enabled again. This allows iterating over these
876 arrays, without the need to check the array size before.
877
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000878- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000879 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000880 /dev/null in certain cases; this is now fixed.
881
Thomas Heller47d7a062006-07-12 08:43:47 +0000882- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
883 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000884
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000885- Because of a misspelled preprocessor symbol, ctypes was always
886 compiled without thread support; this is now fixed.

Gregory P. Smith641cddf2006-07-28 01:35:25 +0000888- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
889 methods now allow their database parameter to be None as the
890 sleepycat API allows.

896-----
897
898- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
899 how long the test file should take to play. Now accepts taking 2.93 secs
900 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
901
Georg Brandl4793aa32006-07-28 18:31:39 +0000902- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
903 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
904 run via ``regrtest.py``. Now they do.

913
914- PythonLauncher now works correctly when the path to the script contains
915 characters that are treated specially by the shell (such as quotes).
916
917- Bug #1527397: PythonLauncher now launches scripts with the working directory
918 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000919 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000920 expect.

928Core and builtins
929-----------------
930
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000931- Bug #1441486: The literal representation of -(sys.maxint - 1)
932 again evaluates to a int object, not a long.
933
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000934- Bug #1501934: The scope of global variables that are locally assigned
935 using augmented assignment is now correctly determined.
936
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000937- Bug #927248: Recursive method-wrapper objects can now safely
938 be released.
939
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000940- Bug #1417699: Reject locale-specific decimal point in float()
941 and atof().
942
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000943- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
944 omit a default "error" argument for NULL pointer. This allows
945 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000946
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000947- Bug #1519018: 'as' is now validated properly in import statements.
948
Neal Norwitz28746ab2006-07-09 22:14:42 +0000949- On 64 bit systems, int literals that use less than 64 bits are
950 now ints rather than longs.
951
Neal Norwitzed657552006-07-10 00:04:44 +0000952- Bug #1512814, Fix incorrect lineno's when code at module scope
953 started after line 256.
954
Tim Peters32a83612006-07-10 21:08:24 +0000955- New function ``sys._current_frames()`` returns a dict mapping thread
956 id to topmost thread stack frame. This is for expert use, and is
957 especially useful for debugging application deadlocks. The functionality
958 was previously available in Fazal Majid's ``threadframe`` extension
959 module, but it wasn't possible to do this in a wholly threadsafe way from
960 an extension.

969
Tim Peters32a83612006-07-10 21:08:24 +0000970- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000971 environment variable to be set in order to the SDK environment
972 for finding the compiler, include files, etc.

977
Thomas Woutersadd19112006-07-05 11:03:49 +0000978- string.Template() now correctly handles tuple-values. Previously,
979 multi-value tuples would raise an exception and single-value tuples would
980 be treated as the value they contain, instead.
981
Martin v. Löwisede77f52006-07-03 13:01:35 +0000982- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
983 even if some data are received.
984
Martin v. Löwis45482392006-07-03 12:28:58 +0000985- Bug #1267547: Put proper recursive setup.py call into the
986 spec file generated by bdist_rpm.

989 degrees and radians.
990
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000991- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000992 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000993
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000994- Bug #1514703: Only setup canvas window in turtle when the canvas
995 is created.
996
Martin v. Löwis7596e832006-07-01 15:33:37 +0000997- Bug #1513223: .close() of a _socketobj now releases the underlying
998 socket again, which then gets closed as it becomes unreferenced.

1001 attribute values.
1002
1003- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1004 sgmllib ('[' and ']' were not accepted).
1005
Georg Brandl1be63af2006-06-28 20:23:25 +00001006- Fix a bug in the turtle module's end_fill function.
1007
Brett Cannon53ab5b72006-06-22 16:49:14 +00001008- Bug #1510580: The 'warnings' module improperly required that a Warning
1009 category be either a types.ClassType and a subclass of Warning. The proper
1010 check is just that it is a subclass with Warning as the documentation states.
1011
Georg Brandlad29e632006-06-21 17:45:17 +00001012- The compiler module now correctly compiles the new try-except-finally
1013 statement (bug #1509132).
1014
Neal Norwitz60373cd2006-06-22 06:30:50 +00001015- The wsgiref package is now installed properly on Unix.
1016
Vinay Sajip28e57612006-07-01 10:45:20 +00001017- A bug was fixed in logging.config.fileConfig() which caused a crash on
1018 shutdown when fileConfig() was called multiple times.
1019
Gerhard Häring762fbd32006-07-02 17:48:30 +00001020- The sqlite3 module did cut off data from the SQLite database at the first
1021 null character before sending it to a custom converter. This has been fixed
1022 now.
1023
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001024Extension Modules
1025-----------------
1026
Tim Peters112aad32006-07-19 00:03:19 +00001027- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1028 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1029 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001030
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001031- Assigning None to pointer type fields in ctypes structures possible
1032 overwrote the wrong fields, this is fixed now.
1033
1034- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1035 on non-Windows platforms.
1036
1037- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1038 integer or long, without range checking.
1039
1040- Patch #1517790: It is now possible to use custom objects in the ctypes
1041 foreign function argtypes sequence as long as they provide a from_param
1042 method, no longer is it required that the object is a ctypes type.
1043
1044- The '_ctypes' extension module now works when Python is configured
1045 with the --without-threads option.
1046
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001047- Bug #1513646: os.access on Windows now correctly determines write
1048 access, again.
1049
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001050- Bug #1512695: cPickle.loads could crash if it was interrupted with
1051 a KeyboardInterrupt.
1052
Neal Norwitza12aa882006-07-06 06:45:08 +00001053- Bug #1296433: parsing XML with a non-default encoding and
1054 a CharacterDataHandler could crash the interpreter in pyexpat.
1055
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001056- Patch #1516912: improve Modules support for OpenVMS.
1057
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001058Build
1059-----
1060
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001061- Automate Windows build process for the Win64 SSL module.
1062
Tim Peters32a83612006-07-10 21:08:24 +00001063- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001064 Previously, the slight difference could cause compilation errors of the
1065 'zlib' module on systems with more than one version of zlib.
1066
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001067- The MSI compileall step was fixed to also support a TARGETDIR
1068 with spaces in it.
1069
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001070- Bug #1517388: sqlite3.dll is now installed on Windows independent
1071 of Tcl/Tk.
1072
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001073- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001074 trying to be installed even though it's empty.

Neal Norwitzb15ac312006-06-29 04:10:08 +00001076Tests
1077-----
1078
1079- Call os.waitpid() at the end of tests that spawn child processes in order
1080 to minimize resources (zombies).
1081
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001082Documentation
1083-------------
1084
Nick Coghlan2d792252006-07-06 13:47:18 +00001085- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1086 documentation for the warnings module.
1087
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001088- Patch #1509163: MS Toolkit Compiler no longer available.
1089
Neal Norwitz56640df2006-07-10 02:36:41 +00001090- Patch #1504046: Add documentation for xml.etree.

1099-----------------
1100
Georg Brandla56b9152006-06-19 06:35:54 +00001101- Patch #1507676: Error messages returned by invalid abstract object operations
1102 (such as iterating over an integer) have been improved and now include the
1103 type of the offending object to help with debugging.
1104
Brett Cannonea3912b2006-06-13 21:46:41 +00001105- Bug #992017: A classic class that defined a __coerce__() method that returned
1106 its arguments swapped would infinitely recurse and segfault the interpreter.
1107
Neal Norwitz909eb122006-06-12 02:13:21 +00001108- Fix the socket tests so they can be run concurrently.
1109
Neal Norwitzb9845e72006-06-12 02:11:18 +00001110- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001111 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001112
Brett Cannon22565aa2006-06-09 22:31:23 +00001113- Bug #532646: object.__call__() will continue looking for the __call__
1114 attribute on objects until one without one is found. This leads to recursion
1115 when you take a class and set its __call__ attribute to an instance of the
1116 class. Originally fixed for classic classes, but this fix is for new-style.
1117 Removes the infinite_rec_3 crasher.
1118
Georg Brandl24250812006-06-09 18:45:48 +00001119- The string and unicode methods startswith() and endswith() now accept
1120 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1121
Brett Cannonde3b0522006-06-08 17:00:45 +00001122- Buffer objects, at the C level, never used the char buffer
1123 implementation even when the char buffer for the wrapped object was
1124 explicitly requested (originally returned the read or write buffer).
1125 Now a TypeError is raised if the char buffer is not present but is
1126 requested.
1127
Georg Brandlddbaa662006-06-04 21:56:52 +00001128- Patch #1346214: Statements like "if 0: suite" are now again optimized
1129 away like they were in Python 2.4.
1130
Georg Brandlb7c8f542006-05-27 12:30:25 +00001131- Builtin exceptions are now full-blown new-style classes instead of
1132 instances pretending to be classes, which speeds up exception handling
1133 by about 80% in comparison to 2.5a2.
1134
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001135- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1136 Unicode 4.1.
1137
Georg Brandlf4ef1162006-05-26 18:03:31 +00001138- Patch #921466: sys.path_importer_cache is now used to cache valid and
1139 invalid file paths for the built-in import machinery which leads to
1140 fewer open calls on startup.
1141
Tim Peters696cf432006-05-24 21:10:40 +00001142- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1143 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1144 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1145 the number of input digits (it was and remains linear-time for bases
1146 2, 4, 8, 16 and 32).
1147
Tim Petersb713ec22006-05-23 18:45:30 +00001148- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1149 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1150 an integer close to ``sys.maxint``. This was repaired by patch
1151 #1335972, which also gives a nice speedup.
1152
Richard Jonescebbefc2006-05-23 18:28:17 +00001153- Patch #1337051: reduced size of frame objects.
1154
1155- PyErr_NewException now accepts a tuple of base classes as its
1156 "base" parameter.
1157
Richard Jones7c88dcc2006-05-23 10:37:38 +00001158- Patch #876206: function call speedup by retaining allocated frame
1159 objects.
1160
Georg Brandl7b90e162006-05-18 07:01:27 +00001161- Bug #1462152: file() now checks more thoroughly for invalid mode
1162 strings and removes a possible "U" before passing the mode to the
1163 C library function.
1164
Neal Norwitz1004a532006-05-15 07:17:23 +00001165- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1166
Neal Norwitz373f0a72006-05-15 07:04:36 +00001167- Bug #1487966: Fix SystemError with conditional expression in assignment
1168
Martin v. Löwis879768d2006-05-11 13:28:43 +00001169- WindowsError now has two error code attributes: errno, which carries
1170 the error values from errno.h, and winerror, which carries the error
1171 values from winerror.h. Previous versions put the winerror.h values
1172 (from GetLastError()) into the errno attribute.
1173
Martin v. Löwis77736712006-05-04 05:51:03 +00001174- Patch #1475845: Raise IndentationError for unexpected indent.
1175
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001176- Patch #1479181: split open() and file() from being aliases for each other.
1177
Tim Peters44bd9862006-06-01 13:49:23 +00001178- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1179 methods were always silently ignored by dictionaries when comparing keys.
1180 They are now passed through (except when using the C API function
1181 ``PyDict_GetItem()``, whose semantics did not change).
1182
1183- Bug #1456209: In some obscure cases it was possible for a class with a
1184 custom ``__eq__()`` method to confuse dict internals when class instances
1185 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1186 No, you don't have any code that did this ;-)

1194
Brett Cannon6ee7d012006-06-08 16:23:04 +00001195- Change binascii.hexlify to accept a read-only buffer instead of only a char
1196 buffer and actually follow its documentation.
1197
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001198- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1199
Nick Coghlanc649ec52006-05-29 12:43:05 +00001200- Patch #1478788 (modified version): The functional extension module has
1201 been renamed to _functools and a functools Python wrapper module added.
1202 This provides a home for additional function related utilities that are
1203 not specifically about functional programming. See PEP 309.
1204
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001205- Patch #1493701: performance enhancements for struct module.
1206
Georg Brandl378d5922006-05-17 14:26:50 +00001207- Patch #1490224: time.altzone is now set correctly on Cygwin.
1208
Georg Brandl8d3342b2006-05-16 07:38:27 +00001209- Patch #1435422: zlib's compress and decompress objects now have a
1210 copy() method.
1211
Andrew MacIntyre92913322006-06-13 15:04:24 +00001212- Patch #1454481: thread stack size is now tunable at runtime for thread
1213 enabled builds on Windows and systems with Posix threads support.
1214
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001215- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1216 (up to the system limit of 32K characters).
1217
1218- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1219 As a result, these functions now raise WindowsError instead of OSError.
1220
Tim Peters7a822da2006-05-25 21:50:17 +00001221- ``time.clock()`` on Win64 should use the high-performance Windows
1222 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1223 Windows platforms).
1224
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001225- Calling Tk_Init twice is refused if the first call failed as that
1226 may deadlock.
1227
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001228- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1229 accept it without potentially using an uninitialized pointer.
1230
1231- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1232 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1233 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001234
Gregory P. Smith372b5832006-06-05 18:48:21 +00001235- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001236 [pybsddb project SF patch number 1466734]
1237
Gregory P. Smith372b5832006-06-05 18:48:21 +00001238- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1239 parameter is supplied. [SF pybsddb bug #1477863]
1240
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001241- bsddb: the __len__ method of a DB object has been fixed to return correct
1242 results. It could previously incorrectly return 0 in some cases.
1243 Fixes SF bug 1493322 (pybsddb bug 1184012).
1244
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001245- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1246 aborts the db transaction safely when a modifier callback fails.
1247 Fixes SF python patch/bug #1408584.
1248
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001249- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001250 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001251 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1252 database calls that would previously deadlock. [SF python bug #775414]
1253
Vinay Sajip28e57612006-07-01 10:45:20 +00001254- Patch #1446489: add support for the ZIP64 extensions to zipfile.

Georg Brandl83cc0d02006-06-14 08:50:03 +00001275- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1276 mime.types file for determining MIME types.
1277
Georg Brandl2605ca82006-06-14 06:08:31 +00001278- Bug #1339007: Shelf objects now don't raise an exception in their
1279 __del__ method when initialization failed.
1280
Martin v. Löwisd8251432006-06-14 05:21:04 +00001281- Patch #1455898: The MBCS codec now supports the incremental mode for
1282 double-byte encodings.
1283
Tim Peters43898b42006-06-14 04:09:25 +00001284- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1285 guarantee that adjacent triples in the return list always describe
1286 non-adjacent blocks. Previously, a pair of matching blocks could end
1287 up being described by multiple adjacent triples that formed a partition
1288 of the matching pair.
1289
Greg Ward0e0c9f42006-06-11 16:24:11 +00001290- Bug #1498146: fix optparse to handle Unicode strings in option help,
1291 description, and epilog.
1292
Greg Wardd1c797e2006-06-11 14:42:41 +00001293- Bug #1366250: minor optparse documentation error.
1294
Greg Ward7f547402006-06-11 00:40:49 +00001295- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1296 clarify docs.
1297
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001298- The wsgiref package has been added to the standard library.
1299
Nick Coghlan676725d2006-06-08 13:54:49 +00001300- The functions update_wrapper() and wraps() have been added to the functools
1301 module. These make it easier to copy relevant metadata from the original
1302 function when writing wrapper functions.
1303
Tim Petersd6a9eef2006-06-05 01:48:21 +00001304- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1305 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001306
Martin v. Löwis3f767792006-06-04 19:36:28 +00001307- Patch #1359618: Speed up charmap encoder by using a trie structure
1308 for lookup.
1309
Tim Petersd609b1a2006-06-02 23:22:51 +00001310- The functions in the ``pprint`` module now sort dictionaries by key
1311 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1312 if and only if its display required more than one line, although that
1313 wasn't documented. The new behavior increases predictability; e.g.,
1314 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1315
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001316- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1317 (thanks for J. J. Lee).
1318
Georg Brandl2b330372006-05-28 20:23:12 +00001319- Patch #1496206: improve urllib2 handling of passwords with respect to
1320 default HTTP and HTTPS ports.
1321
George Yoshidaf3c65de2006-05-28 16:39:09 +00001322- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1323
Bob Ippolito7298f272006-05-23 18:43:47 +00001324- Patch #1281707: speed up gzip.readline.
1325
Georg Brandlb89316f2006-05-17 15:51:16 +00001326- Patch #1180296: Two new functions were added to the locale module:
1327 format_string() to get the effect of "format % items" but locale-aware,
1328 and currency() to format a monetary number with currency sign.
1329
Georg Brandle3a25832006-05-17 14:56:04 +00001330- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1331 and several features added, such as speed and geometry control.
1332
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001333- Patch #1488881: add support for external file objects in bz2 compressed
1334 tarfiles.
1335
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001336- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1337 stdout arguments, making it possible to redirect input and output
1338 for remote debugging.
1339
1340- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1341 a couple of issues, notably handling of long file names using the
1342 GNU LONGNAME extension.
1343
1344- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1345 new flag when ``name`` is already the name of an option flag.
1346
1347- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1348 package.
1349
1350- Patch #1472854: make the rlcompleter.Completer class usable on non-
1351 UNIX platforms.
1352
1353- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1354
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001355- Bug #1472827: correctly escape newlines and tabs in attribute values in

1391Core and builtins
1392-----------------
1393
Thomas Heller1b046642006-04-18 18:51:06 +00001394- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1395 by converting these apis from macros into exported functions again:
1396
1397 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1398 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1399 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1400 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1401 PyRun_String Py_CompileString
1402
Martin v. Löwis45294a92006-04-18 06:24:08 +00001403- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1404
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001405- All uses of PyStructSequence_InitType have been changed to initialize
1406 the type objects only once, even if the interpreter is initialized
1407 multiple times.
1408
Neal Norwitz61546162006-04-14 05:20:28 +00001409- Bug #1454485, array.array('u') could crash the interpreter. This was
1410 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1411 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1412
1413- Py_UNICODE is unsigned. It was always documented as unsigned, but
1414 due to a bug had a signed value in previous versions.
1415
Tim Peters3a5e8b12006-04-11 01:44:07 +00001416- Patch #837242: ``id()`` of any Python object always gives a positive
1417 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1418 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001419 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001420 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001421
Tim Peters3a5e8b12006-04-11 01:44:07 +00001422 def __hash__(self):
1423 return id(self) # WRONG
1424
1425 because a hash result must be a (short) Python int but it was always
1426 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001427 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001428 was always usable as a hash value before this patch. That's no longer
1429 necessarily so.
1430
1431- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001432 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001433 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001434 #1454844)
1435
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001436- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1437 involving generators that have paused outside of any ``try`` or ``with``
1438 blocks. (In 2.5a1, a paused generator that was part of a reference
1439 cycle could not be garbage collected, regardless of whether it was
1440 paused in a ``try`` or ``with`` block.)

1452
1453- Bug #1117761: bsddb.*open() no longer raises an exception when using
1454 the cachesize parameter.
1455
1456- Bug #1149413: bsddb.*open() no longer raises an exception when using
1457 a temporary db (file=None) with the 'n' flag to truncate on open.
1458
1459- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1460 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001461
Armin Rigoa9017c32006-04-19 11:50:27 +00001462- Patch #1062014: AF_UNIX sockets under Linux have a special

1466-------
1467
Peter Astrand7d1d4362006-07-14 14:04:45 +00001468- Bug #1223937: subprocess.CalledProcessError reports the exit status
1469 of the process using the returncode attribute, instead of
1470 abusing errno.
1471
Tim Peters711bf302006-04-25 03:31:36 +00001472- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1473 a doctest to be skipped (the code is not run, and the expected output
1474 or exception is ignored).
1475
Nick Coghlanda2268f2006-04-24 04:37:15 +00001476- Fixed contextlib.nested to cope with exceptions being raised and
1477 caught inside exit handlers.
1478
Greg Wardab05edc2006-04-23 03:47:58 +00001479- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1480 hex, octal, or binary; add ``append_const`` action; keep going if
1481 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1482 added ``epilog`` for better help generation).
1483
Tim Peters21fbd572006-04-21 21:18:10 +00001484- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1485 called from a thread spawned as a side effect of importing a module.
1486
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001487- The pydoc module now supports documenting packages contained in
1488 .zip or .egg files.
1489
1490- The pkgutil module now has several new utility functions, such
1491 as ``walk_packages()`` to support working with packages that are either
1492 in the filesystem or zip files.
1493
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001494- The mailbox module can now modify and delete messages from
1495 mailboxes, in addition to simply reading them. Thanks to Gregory
1496 K. Johnson for writing the code, and to the 2005 Google Summer of
1497 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001498
Tim Petersc7605f22006-04-17 21:12:33 +00001499- The ``__del__`` method of class ``local`` in module ``_threading_local``

1524
Anthony Baxter51bcb682006-04-05 14:51:42 +00001525Build
1526-----
1527
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001528- The Makefile now has a reindent target, which runs reindent.py on
1529 the library.
1530
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001531- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001534
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001535- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1536 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001537 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001538 CXX from --with-cxx-main, see description in README.
1539

1545 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1546 and "%zu" for unsigned integers of type ``size_t``.
1547
Anthony Baxter51bcb682006-04-05 14:51:42 +00001548Tests
1549-----
1550
Nick Coghlanda2268f2006-04-24 04:37:15 +00001551- test_contextlib now checks contextlib.nested can cope with exceptions
1552 being raised and caught inside exit handlers.
1553
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001554- test_cmd_line now checks operation of the -m and -c command switches
1555
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001556- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1557 it separately and by hand. It also wasn't cleaning up its changes to
1558 the current Decimal context.
1559
Thomas Woutersabd08882006-04-26 15:53:30 +00001560- regrtest.py now has a -M option to run tests that test the new limits of
1561 containers, on 64-bit architectures. Running these tests is only sensible
1562 on 64-bit machines with more than two gigabytes of memory. The argument
1563 passed is the maximum amount of memory for the tests to use.

Tim Petersb06d28c2006-05-12 01:57:59 +00001574- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1575
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001576- PEP 343: Added Context Types section to the library reference
1577 and attempted to bring other PEP 343 related documentation into
1578 line with the implementation and/or python-dev discussions.
1579
Tim Peters8dc73d22006-04-24 02:03:16 +00001580- Bug #1337990: clarified that ``doctest`` does not support examples
1581 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001584What's New in Python 2.5 alpha 1?
1585=================================
1586
Anthony Baxterebed3f62006-04-03 15:03:44 +00001587*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001588
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001589Core and builtins
1590-----------------
1591
Nick Coghlan43832302006-04-23 17:04:07 +00001592- PEP 338: -m command line switch now delegates to runpy.run_module
1593 allowing it to support modules in packages and zipfiles
1594
Martin v. Löwisc661b882006-04-20 04:54:23 +00001595- On Windows, .DLL is not an accepted file name extension for
1596 extension modules anymore; extensions are only found if they
1597 end in .PYD.
1598
Martin v. Löwisea62d252006-04-03 10:56:49 +00001599- Bug #1421664: sys.stderr.encoding is now set to the same value as
1600 sys.stdout.encoding.
1601
Neal Norwitz92e212f2006-04-03 04:48:37 +00001602- __import__ accepts keyword arguments.
1603
Georg Brandlccadf842006-03-31 18:54:53 +00001604- Patch #1460496: round() now accepts keyword arguments.
1605
Anthony Baxter262c00a2006-03-30 10:53:17 +00001606- Fixed bug #1459029 - unicode reprs were double-escaped.
1607
Hye-Shik Changd478f342006-03-23 12:32:36 +00001608- Patch #1396919: The system scope threads are reenabled on FreeBSD
1609 5.4 and later versions.
1610
Neal Norwitze98ccf62006-03-23 05:39:47 +00001611- Bug #1115379: Compiling a Unicode string with an encoding declaration
1612 now gives a SyntaxError.
1613
Georg Brandlabd1ff82006-03-18 07:59:59 +00001614- Previously, Python code had no easy way to access the contents of a
1615 cell object. Now, a ``cell_contents`` attribute has been added
1616 (closes patch #1170323).
1617
Tim Peterscf79aac2006-03-16 01:14:46 +00001618- Patch #1123430: Python's small-object allocator now returns an arena to
1619 the system ``free()`` when all memory within an arena becomes unused
1620 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1621 freed. Some applications will see a drop in virtual memory size now,
1622 especially long-running applications that, from time to time, temporarily
1623 use a large number of small objects. Note that when Python returns an
1624 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001625 platform C library will in turn return that memory to the operating system.
1626 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001627 appears to be effective at least on Microsoft C and gcc-based systems.
1628 Thanks to Evan Jones for hard work and patience.
1629
Georg Brandl533ff6f2006-03-08 18:09:27 +00001630- Patch #1434038: property() now uses the getter's docstring if there is
1631 no "doc" argument given. This makes it possible to legitimately use
1632 property() as a decorator to produce a read-only property.
1633
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001634- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1635 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1636 of requiring an int or long in slicing and a few other contexts, enabling
1637 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1638
Neal Norwitz995acdf2006-03-07 05:01:00 +00001639- Fixed various bugs reported by Coverity's Prevent tool.
1640
Brett Cannonbf364092006-03-01 04:25:17 +00001641- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1642 new exception base class, BaseException, which has a new message attribute.
1643 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1644 Raising a string exception now raises a DeprecationWarning.
1645
Thomas Woutersfb609f42006-02-28 16:37:25 +00001646- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1647 explicitly relative, using 'from .module import name' to mean 'from the same
1648 package as this module is in. Imports without dots still default to the
1649 old relative-then-absolute, unless 'from __future__ import
1650 absolute_import' is used.
1651
Brett Cannona7446e32006-02-27 23:39:10 +00001652- Properly check if 'warnings' raises an exception (usually when a filter set
1653 to "error" is triggered) when raising a warning for raising string
1654 exceptions.
1655
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001656- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001657 The name was removed from Include/code.h.
1658
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001659- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001660
Guido van Rossum1968ad32006-02-25 22:38:04 +00001661- Patch 1433928:
1662 - The copy module now "copies" function objects (as atomic objects).
1663 - dict.__getitem__ now looks for a __missing__ hook before raising
1664 KeyError.
1665
Tim Peters84ef21c2006-02-28 20:39:06 +00001666- PEP 343: with statement implemented. Needs ``from __future__ import
1667 with_statement``. Use of 'with' as a variable will generate a warning.
1668 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001669 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001670 The following objects have __context__ methods:
1671 - The built-in file type.
1672 - The thread.LockType type.
1673 - The following types defined by the threading module:
1674 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1675 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001676
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001677- Fix the encodings package codec search function to only search
1678 inside its own package. Fixes problem reported in patch #1433198.
1679
1680 Note: Codec packages should implement and register their own
1681 codec search function. PEP 100 has the details.
1682
Tim Peters9ea89d22006-06-04 03:26:02 +00001683- PEP 353: Using ``Py_ssize_t`` as the index type.
1684
1685- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1686 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1687 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1688 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1689 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001690
Neal Norwitzfc76d632006-01-10 06:03:13 +00001691- Patch #1400181, fix unicode string formatting to not use the locale.
1692 This is how string objects work. u'%f' could use , instead of .
1693 for the decimal point. Now both strings and unicode always use periods.
1694
Neal Norwitz671b9e32006-01-09 07:07:12 +00001695- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1696 configure would break checking curses.h.
1697
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001698- Bug #959576: The pwd module is now builtin. This allows Python to be
1699 built on UNIX platforms without $HOME set.
1700
Neal Norwitzc10978f2005-12-19 06:07:16 +00001701- Bug #1072182, fix some potential problems if characters are signed.
1702
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001703- Bug #889500, fix line number on SyntaxWarning for global declarations.
1704
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001705- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1706
Neal Norwitze7214a12005-12-18 05:03:17 +00001707- Support for converting hex strings to floats no longer works.
1708 This was not portable. float('0x3') now raises a ValueError.
1709
Barry Warsaw2a38a862005-12-18 01:27:35 +00001710- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001711 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001712 is now displayed in interactive prompt banner.
1713
Georg Brandlfa166682005-12-17 21:45:17 +00001714- Implementation of PEP 341 - Unification of try/except and try/finally.
1715 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001716 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001717
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001718- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1719 now encodes backslash correctly.
1720
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001721- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1722
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001723- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001724 and long longs.
1725
Neal Norwitz67715f02005-11-09 06:59:35 +00001726- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001727 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001728 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001729
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001730- Replaced most Unicode charmap codecs with new ones using the
1731 new Unicode translate string feature in the builtin charmap
1732 codec; the codecs were created from the mapping tables available
1733 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1734 encodings now include a mapping for the Apple logo)
1735
Tim Peterse3547fd2005-12-16 23:13:57 +00001736- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001737
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001738- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001739
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001740- A new AST parser implementation was completed. The abstract
1741 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001742 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001743
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001744- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001745 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1746
Neal Norwitz708e51a2005-10-03 04:48:15 +00001747- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1748
Neal Norwitz11bd1192005-10-03 00:54:56 +00001749- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1750 Provide a warning when a directory is passed on the command line.
1751
Neal Norwitz40d37812005-10-02 01:48:49 +00001752- Fix segfault with invalid coding.
1753
1754- SF bug #772896: unknown encoding results in MemoryError.
1755
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001756- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001757 supported a __len__() method which evaluated to False when the iterator
1758 was empty.
1759
Guido van Rossum630db602005-09-20 18:49:54 +00001760- On 64-bit platforms, when __len__() returns a value that cannot be
1761 represented as a C int, raise OverflowError.
1762
Skip Montanarof8948ca2005-09-19 03:54:46 +00001763- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001764 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001765
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001766- SF bug #893549: parsing keyword arguments was broken with a few format
1767 codes.
1768
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001769- Changes donated by Elemental Security to make it work on AIX 5.3
1770 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1771 bug #105470: test_pwd fails on 64bit system (Opteron).
1772
Guido van Rossum539c6622005-09-14 17:49:54 +00001773- Changes donated by Elemental Security to make it work on HP-UX 11 on
1774 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1775
Georg Brandl4550b8d2005-08-26 06:43:52 +00001776- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001777 (fixes bug #1119418).
1778
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001779- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1780
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001781- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1782 exceptions that cause a function to exit.
1783
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001784- The implementation of set() and frozenset() was revised to use its
1785 own internal data structure. Memory consumption is reduced by 1/3
1786 and there are modest speed-ups as well. The API is unchanged.
1787
Tim Petersde7990b2005-07-17 23:45:23 +00001788- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1789
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001790- SF bug #1229429: PyObject_CallMethod failed to decrement some
1791 reference counts in some error exit cases.
1792
Tim Petersecc6e6a2005-07-10 22:30:55 +00001793- SF bug #1185883: Python's small-object memory allocator took over
1794 a block managed by the platform C library whenever a realloc specified
1795 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001796 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001797 portable way to copy data from the C-managed block into Python's
1798 small-object space without risking a memory fault. Python's small-object
1799 realloc now leaves such blocks under the control of the platform C
1800 realloc.
1801
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001802- SF bug #1232517: An overflow error was not detected properly when
1803 attempting to convert a large float to an int in os.utime().
1804
Raymond Hettinger3296e692005-06-29 23:29:56 +00001805- SF bug #1224347: hex longs now print with lowercase letters just
1806 like their int counterparts.
1807
Michael W. Hudson188d4362005-06-20 16:52:57 +00001808- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1809 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1810 interpreter states; back out that fix and do a better job (see
1811 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1812 for a longer write-up of the problem).
1813
Michael W. Hudsondf888462005-06-03 14:41:55 +00001814- SF patch #1180995: marshal now uses a binary format by default when
1815 serializing floats.
1816
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001817- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1818 the routines that promise to produce IEEE 754 binary representations
1819 of floats now simply copy bytes around.
1820
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001821- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1822 278.
1823
Brett Cannonc3647ac2005-04-26 03:45:26 +00001824- patch #1109424: int, long, float, complex, and unicode now check for the
1825 proper magic slot for type conversions when subclassed. Previously the
1826 magic slot was ignored during conversion. Semantics now match the way
1827 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001828 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001829 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001830 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001831
Barry Warsawc8d907c2005-04-19 23:43:40 +00001832- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1833 NULL, now raise an AttributeError when attempting to set or delete the
1834 attribute. Previously a TypeError was raised, but this was inconsistent
1835 with the equivalent pure-Python implementation.
1836
Michael W. Hudson774479c2005-04-18 08:46:17 +00001837- It is now safe to call PyGILState_Release() before
1838 PyEval_InitThreads() (note that if there is reason to believe there
1839 are multiple threads around you still must call PyEval_InitThreads()
1840 before using the Python API; this fix is for extension modules that
1841 have no way of knowing if Python is multi-threaded yet).
1842
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001843- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1844 disabled caused a crash.
1845
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001846- Bug #1165306: instancemethod_new allowed the creation of a method
1847 with im_class == im_self == NULL, which caused a crash when called.
1848
Tim Petersecc6e6a2005-07-10 22:30:55 +00001849- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001850 fixes the crash seen in bug #1165761
1851
Raymond Hettinger96229b12005-03-11 06:49:40 +00001852- Added two new builtins, any() and all().
1853
Brett Cannon409d8f22005-03-05 06:47:57 +00001854- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001855 (e.g., ``class C(): pass`` is no longer a syntax error).
1856 Patch #1176012 added support to the 'parser' module and 'compiler' package
1857 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001858
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001859- Patch #1115086: Support PY_LONGLONG in structmember.
1860
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001861- Bug #1155938: new style classes did not check that __init__() was
1862 returning None.
1863
Tim Petersecc6e6a2005-07-10 22:30:55 +00001864- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001865 ('\') with a specific error message.
1866
Martin v. Löwisff232d72005-03-03 09:24:38 +00001867- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1868
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001869- Bug #1124295: the __name__ attribute of file objects was
1870 inadvertently made inaccessible in restricted mode.
1871
Tim Petersecc6e6a2005-07-10 22:30:55 +00001872- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001873 an ferror() call.
1874
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001875- min() and max() now support key= arguments with the same meaning as in
1876 list.sort().
1877
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001878- The peephole optimizer now performs simple constant folding in expressions:
1879 (2+3) --> (5).
1880
Raymond Hettingera422c342005-01-11 03:03:27 +00001881- set and frozenset objects can now be marshalled. SF #1098985.
1882
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001883- Bug #1077106: Poor argument checking could cause memory corruption
1884 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001885
Jeremy Hyltonab630502005-02-04 18:44:06 +00001886- The parser did not complain about future statements in illegal
1887 positions. It once again reports a syntax error if a future
1888 statement occurs after anything other than a doc string.
1889
Neil Schemenauercf52c072005-08-12 17:34:58 +00001890- Change the %s format specifier for str objects so that it returns a
1891 unicode instance if the argument is not an instance of basestring and
1892 calling __str__ on the argument returns a unicode instance.
1893
Tim Petersf4e69282006-02-27 17:15:31 +00001894- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1895 current thread state when the auto-GIL-state machinery knows about
1896 it (since the thread state is being deleted, continuing to remember it
1897 can't help, but can hurt if another thread happens to get created with
1898 the same thread id).
1899
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001900Extension Modules

1925
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001926- The unicodedata module was updated to the 4.1 version of the Unicode
1927 database. The 3.2 version is still available as unicodedata.db_3_2_0
1928 for applications that require this specific version (such as IDNA).
1929
Neal Norwitzb62c4332006-03-04 18:35:47 +00001930- The timing module is no longer built by default. It was deprecated
1931 in PEP 4 in Python 2.0 or earlier.
1932
Guido van Rossum1968ad32006-02-25 22:38:04 +00001933- Patch 1433928: Added a new type, defaultdict, to the collections module.
1934 This uses the new __missing__ hook behavior added to dict (see above).
1935
Georg Brandldbd83392006-02-20 09:42:33 +00001936- Bug #854823: socketmodule now builds on Sun platforms even when

1938
Georg Brandlf4f44152006-02-18 22:29:33 +00001939- Patch #1393157: os.startfile() now has an optional argument to specify
1940 a "command verb" to invoke on the file.
1941

1951
Martin v. Löwis14694662006-02-03 12:54:16 +00001952- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1953 are reported, the limit on path name lengths is removed, and stat reports
1954 WindowsError now (instead of OSError).
1955
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001956- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

2031 the request code argument, which results in more C-like behaviour
2032 for large or negative values.
2033
Tim Petersecc6e6a2005-07-10 22:30:55 +00002034- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002090- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2091 been renamed to have only a single underscore prefix. This was done to
2092 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002093
Nick Coghlan43832302006-04-23 17:04:07 +00002094- PEP 338: new module runpy defines a run_module function to support
2095 executing modules which provide access to source code or a code object
2096 via the PEP 302 import mechanisms.
2097
Anthony Baxter93f5b932006-04-03 08:05:07 +00002098- The email module's parsedate_tz function now sets the daylight savings

2106 in attribute values.
2107
Anthony Baxterc51ee692006-04-01 00:57:31 +00002108- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002109 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002110 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002111 module will not be built.
2112
Tim Petersc17976e2006-04-01 00:26:53 +00002113- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2114 aren't officially supported here, and trying to use them will probably
2115 raise an exception some day. But dicts have been allowed, and "mostly
2116 worked", so support for them won't go away without warning.
2117
Georg Brandl338ef7d2006-03-31 18:42:16 +00002118- Bug #1445068: getpass.getpass() can now be given an explicit stream
2119 argument to specify where to write the prompt.
2120

2130 to make it easier to monitor when daemon threads have completed
2131 processing all enqueued tasks. Patch #1455676.
2132

2136
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002137- email 4.0 package now integrated. This is largely the same as the email 3.0
2138 package that was included in Python 2.3, except that PEP 8 module names are
2139 now used (e.g. mail.message instead of email.Message). The MIME classes
2140 have been moved to a subpackage (e.g. email.mime.text instead of
2141 email.MIMEText). The old names are still supported for now. Several
2142 deprecated Message methods have been removed and lots of bugs have been
2143 fixed. More details can be found in the email package documentation.
2144
Walter Dörwald40108c92006-03-27 08:15:44 +00002145- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2146 (a subclass of tuple) that provides incremental decoders and encoders
2147 (a way to use stateful codecs without the stream API). Python functions
2148 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2149 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2150 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002151
Walter Dörwald067db482006-03-15 22:17:27 +00002152- Patch #1359365: Calling next() on a closed StringIO.String object raises
2153 a ValueError instead of a StopIteration now (like file and cString.String do).
2154 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2155 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002156
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002157- A regrtest option -w was added to re-run failed tests in verbose mode.

Tim Peterse3547fd2005-12-16 23:13:57 +00002229 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2230 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2231 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2232 Ronald L. Rivest offered this advice for Python:
2233
2234 "The consensus of researchers in this area (at least as
2235 expressed at the NIST Hash Function Workshop 10/31/05),
2236 is that SHA-256 is a good choice for the time being, but
2237 that research should continue, and other alternatives may
2238 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002239
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002240- Added a subset of Fredrik Lundh's ElementTree package. Available

2305 Tkdnd.
2306
Georg Brandl5dbda752005-07-17 20:27:41 +00002307- Bug #1015140: disambiguated the term "article id" in nntplib docs and
2308 docstrings to either "article number" or "message id".
2309
Georg Brandla4a8b822005-07-15 09:13:21 +00002310- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
2311 parameter, but uses the usual "kwargs=None".
2312
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002313- textwrap now processes text chunks at O(n) speed instead of O(n**2).
Raymond Hettinger8bfa8932005-07-15 06:53:35 +00002314 Patch #1209527 (Contributed by Connelly).
2315
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00002316- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
2317 to W3C name (404 -> 'Not Found'). RFE #1216944.
2318
Georg Brandl9e43acf2005-07-04 17:16:07 +00002319- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2320 as this can cause problems with apps closing all file descriptors.
2321
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002322- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002323 it can be missing in embedded interpreters
Georg Brandl5284b532005-06-26 22:54:58 +00002324
Georg Brandl2f210b62005-06-26 22:09:06 +00002325- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
2326
Georg Brandlfbff1bc2005-06-26 21:36:25 +00002327- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
2328 error messages.
2329
Georg Brandl379f99d2005-06-26 21:09:38 +00002330- Bug #1108948: Cookie.py produced invalid JavaScript code.
2331
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00002332- The tokenize module now detects and reports indentation errors.
2333 Bug #1224621.
2334
Raymond Hettinger68c04532005-06-10 11:05:19 +00002335- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002336 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002337 the generate_tokens() function now accepts a callable argument that
2338 terminates by raising StopIteration.
2339
Georg Brandl9166e1a2005-06-04 09:20:03 +00002340- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2341
Georg Brandl268e61c2005-06-03 14:28:50 +00002342- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2343 component of the path.
2344
Skip Montanaro174dd222005-05-14 20:54:16 +00002345- Patch #1120353: The xmlrpclib module provides better, more transparent,
2346 support for datetime.{datetime,date,time} objects. With use_datetime set
2347 to True, applications shouldn't have to fiddle with the DateTime wrapper
2348 class at all.
2349
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002350- distutils.commands.upload was added to support uploading distribution
2351 files to PyPI.
2352
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002353- distutils.commands.register now encodes the data as UTF-8 before posting
2354 them to PyPI.
2355
Raymond Hettinger267b8682005-03-27 10:47:39 +00002356- decimal operator and comparison methods now return NotImplemented
2357 instead of raising a TypeError when interacting with other types. This
2358 allows other classes to implement __radd__ style methods and have them
2359 work as expected.
2360
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002361- Bug #1163325: Decimal infinities failed to hash. Attempting to
2362 hash a NaN raised an InvalidOperation instead of a TypeError.
2363
Tim Petersecc6e6a2005-07-10 22:30:55 +00002364- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002365 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2366

2398
Guido van Rossumd0641422005-02-03 15:01:24 +00002399- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2400 disables recursive traversal through instance attributes, which can
2401 be exploited in various ways.
2402
Tim Peterse3547fd2005-12-16 23:13:57 +00002403- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002404 flags on the HTTP listening socket.
2405
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002406- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2407 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2408
Fred Drakefbdeaad2006-07-29 16:56:15 +00002409- Patches #893642, #1039083: add allow_none, encoding arguments to
2410 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002411
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002412- Bug #1110478: Revert os.environ.update to do putenv again.
2413
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002414- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2415
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002416- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2417
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002418- Enhancements to the csv module:
2419
2420 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002421 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002422 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002423 + Dialect parameter parsing has been re-implemented to improve error
2424 reporting.
2425 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2426 dictates.
2427 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002428 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002429 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002430 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2431 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002432 + reader now allows \r characters to be quoted (previously it only allowed
2433 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002434 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002435 + Dialect classes passed to the module are no longer instantiated by
2436 the module before being parsed (the former validation scheme required
2437 this, but the mechanism was unreliable).
2438 + The dialect registry now contains instances of the internal
2439 C-coded dialect type, rather than references to python objects.
2440 + the internal c-coded dialect type is now immutable.
2441 + register_dialect now accepts the same keyword dialect specifications
2442 as the reader and writer, allowing the user to register dialects
2443 without first creating a dialect class.
2444 + a configurable limit to the size of parsed fields has been added -
2445 previously, an unmatched quote character could result in the entire
2446 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002447 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002448 the parser field size limit (returning the former limit). The initial
2449 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002450 + A line_num attribute has been added to the reader object, which tracks
2451 the number of lines read from the source iterator. This is not
2452 the same as the number of records returned, as records can span
2453 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002454 + reader and writer objects were not being registered with the cyclic-GC.
2455 This has been fixed.
2456
Brett Cannone6539c42005-01-08 02:43:53 +00002457- _DummyThread objects in the threading module now delete self.__block that is
2458 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2459 lock primitives tend to be limited in number and thus should not be wasted on
2460 a _DummyThread object. Fixes bug #1089632.
2461
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002462- The imghdr module now detects Exif files.
2463
Raymond Hettinger6065d322004-12-20 23:51:53 +00002464- StringIO.truncate() now correctly adjusts the size attribute.
2465 (Bug #951915).
2466
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002467- locale.py now uses an updated locale alias table (built using
2468 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2469 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002470 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002471
Raymond Hettinger3557f422004-12-07 12:02:02 +00002472- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2473
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002474- the pickle module no longer accepts the deprecated None option in the
2475 args tuple returned by __reduce__().
2476
Brett Cannon84667c02004-12-07 03:25:18 +00002477- optparse now optionally imports gettext. This allows its use in setup.py.
2478
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002479- the pickle module no longer uses the deprecated bin parameter.
2480
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002481- the shelve module no longer uses the deprecated binary parameter.
2482
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002483- the pstats module no longer uses the deprecated ignore() method.
2484
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002485- the filecmp module no longer uses the deprecated use_statcache argument.
2486
Raymond Hettinger664347b2004-12-04 21:21:53 +00002487- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2488 extended or overridden by subclasses. Formerly, the subclassed method would
2489 be ignored by the rest of the module. (Bug #1078905).
2490
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002491- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002492 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002493
Walter Dörwald36733692004-12-22 12:50:50 +00002494- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2495 once when a size argument is given. This prevents a buffer overflow in the
2496 tokenizer with very long source lines.
2497
Barry Warsaw538561e2006-01-01 21:48:54 +00002498- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2499 immediately after creating the object, without any intervening
2500 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002501
Skip Montanaro05885812005-01-16 20:48:27 +00002502- The reconvert.quote function can now emit triple-quoted strings. The
2503 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002504
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002505- ``UserString.MutableString`` now supports negative indices in
2506 ``__setitem__`` and ``__delitem__``
2507
Greg Ward40407942005-03-05 02:53:17 +00002508- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2509 correctly.
2510
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002511- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2512 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2513 character even if the user has passed a size parameter to get a proper
2514 line ending. Remove the special handling of a "\r\n" that has been split
2515 between two lines.
2516
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002517- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2518 about illegal code points. The codec now supports PEP 293 style error
2519 handlers.
2520
Walter Dörwald78a78b02005-09-01 12:04:29 +00002521- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002522 from the input stream, so that the output is a byte string in the correct
2523 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002524
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002525- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2526 considering it exactly like a '*'.
2527
Walter Dörwald007f8df2005-10-09 19:42:27 +00002528- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2529 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002530
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002531- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2532
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002533- Patch #1413711: Certain patterns of differences were making difflib
2534 touch the recursion limit.
2535
Walter Dörwald58917a62006-03-31 15:26:22 +00002536- Bug #947906: An object oriented interface has been added to the calendar
2537 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002538 called as a script (e.g. via ``python -mcalendar``). Localized month and
2539 weekday names can be ouput (even if an exotic encoding is used) using
2540 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002541

Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002559- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2560
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002561- Bug #1189330: configure did not correctly determine the necessary
2562 value of LINKCC if python was built with GCC 4.0.
2563
Trent Mick8321b422005-07-26 02:29:21 +00002564- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2565 vulnerability in zlib 1.2.1 and 1.2.2.
2566
Brett Cannon08cd5982005-04-24 22:26:38 +00002567- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2568 flags that change binary compatibility. Changes were also made to
2569 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002570 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002571
Bob Ippolitoed233462005-03-29 13:47:59 +00002572- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2573 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2574 no longer exists). This configure patch makes things right.
2575
Martin v. Löwise2713be2005-03-08 15:03:08 +00002576- Bug #1158607: Build with --disable-unicode again.
2577
Brett Cannon46d96232005-02-16 00:07:19 +00002578- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2579 defined. Discovered as a result of not being able to build on OS X.
2580
Brett Cannon516592f2004-12-07 00:42:59 +00002581- setup.py now uses the directories specified in LDFLAGS using the -L option
2582 and in CPPFLAGS using the -I option for adding library and include
2583 directories, respectively, for compiling extension modules against. This has
2584 led to the core being compiled using the values in CPPFLAGS. It also removes
2585 the need for the special-casing of both DarwinPorts and Fink for darwin since
2586 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2587 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2588 Fink, ``-I/opt/local/include`` for DarwinPorts).
2589
Brett Cannon43802422005-02-10 20:48:03 +00002590- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2591 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2592 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2593 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002595C API
2596-----
2597
Tim Petersc9d78aa2006-03-26 23:27:58 +00002598- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2599 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2600 is obtained via the ``PyObject_`` family, it must be released via the
2601 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2602 always been officially true, but when Python's small-object allocator was
2603 introduced, an attempt was made to cater to a few extension modules
2604 discovered at the time that obtained memory via ``PyObject_New`` but
2605 released it via ``PyMem_DEL``. It's years later, and if such code still
2606 exists it will fail now (probably with segfaults, but calling wrong
2607 low-level memory management functions can yield many symptoms).
2608
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002609- Added a C API for set and frozenset objects.
2610

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002613- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2614 mapping argument now. This string is used as a mapping table. Byte values
2615 greater than the length of the string and 0xFFFE are treated as undefined
2616 mappings.

Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002624- Patch #1276356: New resource "urlfetch" is implemented. This enables
