388
Brett Cannon19d76c52006-09-09 07:18:44 +0000389- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
390 allows calling unicode() on exceptions classes directly to succeed.

409
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000410- Bug #1520864: unpacking singleton tuples in list comprehensions and
411 generator expressions (x for x, in ... ) works again. Fixing this problem
412 required changing the .pyc magic number. This means that .pyc files
413 generated before 2.5c2 will be regenerated.

Neal Norwitz24b6f202006-09-05 04:43:56 +0000522- Fix infinite recursion when subclassing long and overriding __hash__.
523
524- Fix concatenation (+=) of long strings.
525
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000526- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000527 compared equal or unequal to a string and a UnicodeDecodeError
528 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000529
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000530 Instead, the equal (==) and unequal (!=) comparison operators will
531 now issue a UnicodeWarning and interpret the two objects as
532 unequal. The UnicodeWarning can be filtered as desired using
533 the warning framework, e.g. silenced completely, turned into an
534 exception, logged, etc.
535
536 Note that compare operators other than equal and unequal will still
537 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000538
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000539- Fix segfault when doing string formatting on subclasses of long.
540
541- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
542 with new-style classes.
543
544- Fix bug related to __len__ functions returning negative values with
545 classic classes.
546
547- Patch #1538606, Fix __index__() clipping. There were some problems
548 discovered with the API and how integers that didn't fit into Py_ssize_t
549 were handled. This patch attempts to provide enough alternatives
550 to effectively use __index__.
551
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000552- Bug #1536021: __hash__ may now return long int; the final hash
553 value is obtained by invoking hash on the long int.
554
Thomas Hellerab1049c2006-08-08 17:37:00 +0000555- Bug #1536786: buffer comparison could emit a RuntimeWarning.

558 sys.stdin is closed.
559
Thomas Heller74d36f02006-08-04 18:17:40 +0000560- On Windows, the PyErr_Warn function is now exported from
561 the Python dll again.
562
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000563- Bug #1191458: tracing over for loops now produces a line event
564 on each iteration. Fixing this problem required changing the .pyc
565 magic number. This means that .pyc files generated before 2.5c1
566 will be regenerated.
567
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000568- Bug #1333982: string/number constants were inappropriately stored
569 in the byte code and co_consts even if they were not used, ie
570 immediately popped off the stack.

Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000578- Fix a bug in the ``compiler`` package that caused invalid code to be
579 generated for generator expressions.
580
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000581- The distutils version has been changed to 2.5.0. The change to
582 keep it programmatically in sync with the Python version running
583 the code (introduced in 2.5b3) has been reverted. It will continue
584 to be maintained manually as static string literal.
585
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000586- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000587 and this cannot be converted to the required C type, an exception is
588 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000589 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000590
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000591- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000592 an exception.
593
Tim Peterscbdd3502006-09-05 01:47:53 +0000594- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000595 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000596 workarounds for clocks with low resolution, to stop the code yielding
597 duplicate UUIDs.
598
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000599- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
600 before raising SystemExit, allowing IDLE to honor quit() and exit().
601
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000602- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.

613 str(exception) raised an exception.
614
Neil Schemenauer06ded092006-08-04 16:20:30 +0000615- Fix a bug in the ``compiler`` package that caused invalid code to be

631
Thomas Heller86720042006-08-14 11:17:48 +0000632- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
633 uses the _as_parameter_ attribute when objects are passed to foreign

635
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000636- Bug #1530559, struct.pack raises TypeError where it used to convert.

Fred Drake53912162006-07-29 13:22:49 +0000683What's New in Python 2.5 beta 3?
684================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000685
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000686*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000687
688Core and builtins
689-----------------
690
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000691- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000692 returned a long (see PEP 353).
693
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000694- Bug #1515471: string.replace() accepts character buffers again.
695
Neal Norwitz07aadb12006-07-30 06:55:48 +0000696- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
697 This provides the proper warning for struct.pack().
698 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
699
Neal Norwitz0d62a062006-07-30 06:53:31 +0000700- Patch #1531113: Fix augmented assignment with yield expressions.
701 Also fix a SystemError when trying to assign to yield expressions.
702
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000703- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
704 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
705 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
706 excessive filesystem operations during imports.
707
Tim Petersbc24eee2006-07-27 01:14:53 +0000708- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
709 operations on signed longs that are formally undefined by C.
710 Unfortunately, at least one compiler now cares about that, so complicated
711 the code to make that compiler happy again.
712
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000713- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
714
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000715- Patch #1232023: Stop including current directory in search
716 path on Windows.
717
Neal Norwitze1fdb322006-07-21 05:32:28 +0000718- Fix some potential crashes found with failmalloc.
719
Neal Norwitze7563102006-07-17 01:00:16 +0000720- Fix warnings reported by Klocwork's static analysis tool.
721
Neal Norwitz84be93b2006-07-16 01:50:38 +0000722- Bug #1512814, Fix incorrect lineno's when code within a function
723 had more than 255 blank lines.
724
Georg Brandl9dceedb2006-07-12 15:31:17 +0000725- Patch #1521179: Python now accepts the standard options ``--help`` and
726 ``--version`` as well as ``/?`` on Windows.
727
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000728- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000729 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000730 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000731
Tim Peters112aad32006-07-19 00:03:19 +0000732- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000733 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000734 new ``sys._current_frames()`` returns a dictionary with one entry,
735 mapping the faux "thread id" 0 to the current frame.
736
Ronald Oussoren3075e162006-07-25 20:28:55 +0000737- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000738
Ronald Oussoren3075e162006-07-25 20:28:55 +0000739
Neal Norwitza1f10902006-07-12 07:28:29 +0000740Library
741-------
742
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000743- Correction of patch #1455898: In the mbcs decoder, set final=False
744 for stream decoder, but final=True for the decode function.
745
Georg Brandl07fec3a2006-08-01 18:49:24 +0000746- os.urandom no longer masks unrelated exceptions like SystemExit or
747 KeyboardInterrupt.
748
Tim Peters4643c2f2006-08-10 22:45:34 +0000749- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000750 shutil.copytree on Windows
751
Georg Brandle34ac7c2006-07-30 11:07:23 +0000752- Bug #1002398: The documentation for os.path.sameopenfile now correctly
753 refers to file descriptors, not file objects.
754
Tim Peterscbdd3502006-09-05 01:47:53 +0000755- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000756 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000757 #1513611, and probably others.
758
Georg Brandledd9b0d2006-07-29 09:33:26 +0000759- Bug #1441397: The compiler module now recognizes module and function
760 docstrings correctly as it did in Python 2.4.
761
Tim Peters6f681472006-07-27 23:44:37 +0000762- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
763 lost that tests are sorted by name before being run. This rarely
764 matters for well-written tests, but can create baffling symptoms if
765 side effects from one test to the next affect outcomes. ``DocTestFinder``
766 has been changed to sort the list of tests it returns.
767
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000768- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000769 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000770
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000771- Bug #978833: Really close underlying socket in _socketobject.close.
772
Georg Brandldb232dc2006-08-20 13:15:43 +0000773- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
774 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000775
Georg Brandlcf0c1722006-07-26 07:23:32 +0000776- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
777 to recursive calls and call it with the failing package name.
778
Martin v. Löwis0b483032006-07-25 09:53:12 +0000779- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
780
Georg Brandlc13c34c2006-07-24 14:09:56 +0000781- Patch #1515343: Fix printing of deprecated string exceptions with a
782 value in the traceback module.
783
Greg Ward48fae7a2006-07-23 16:05:51 +0000784- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
785
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000786- Patch #1524429: Use repr() instead of backticks in Tkinter again.
787
Brett Cannoncaebe222006-07-18 04:41:36 +0000788- Bug #1520914: Change time.strftime() to accept a zero for any position in its
789 argument tuple. For arguments where zero is illegal, the value is forced to
790 the minimum value that is correct. This is to support an undocumented but
791 common way people used to fill in inconsequential information in the time
792 tuple pre-2.4.
793
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000794- Patch #1220874: Update the binhex module for Mach-O.
795
Barry Warsawb110bad2006-07-21 14:51:07 +0000796- The email package has improved RFC 2231 support, specifically for
797 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
798 (name*0=<blah>) parameter continuations. This may change the types of
799 values returned from email.message.Message.get_param() and friends.
800 Specifically in some cases where non-encoded continuations were used,
801 get_param() used to return a 3-tuple of (None, None, string) whereas now it
802 will just return the string (since non-encoded continuations don't have
803 charset and language parts).
804
805 Also, whereas % values were decoded in all parameter continuations, they are
806 now only decoded in encoded parameter parts.
807
Ronald Oussoren3075e162006-07-25 20:28:55 +0000808- Bug #1517990: IDLE keybindings on MacOS X now work correctly
809
810- Bug #1517996: IDLE now longer shows the default Tk menu when a
811 path browser, class browser or debugger is the frontmost window on MacOS X
812
Barry Warsaw00decd72006-07-27 23:43:15 +0000813- Patch #1520294: Support for getset and member descriptors in types.py,
814 inspect.py, and pydoc.py. Specifically, this allows for querying the type
815 of an object against these built-in types and more importantly, for getting
816 their docstrings printed in the interactive interpreter's help() function.

821
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000822- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
823 a socket operation on a socket with a timeout, the exception will be
824 caught correctly. Previously, the exception was not caught.
825
Thomas Heller1393d6a2006-07-28 21:43:20 +0000826- Patch #1529514: The _ctypes extension is now compiled on more
827 openbsd target platforms.
828
Tim Peters9cab5932006-07-28 00:30:00 +0000829- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
830 a memory leak, affecting pickles and deep copies.
831
Tim Petersbc24eee2006-07-27 01:14:53 +0000832- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

834
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000835- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
836
Thomas Hellerce049a02006-07-14 17:51:14 +0000837- Patch #1521817: Index range checking on ctypes arrays containing
838 exactly one element enabled again. This allows iterating over these
839 arrays, without the need to check the array size before.
840
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000841- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000842 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000843 /dev/null in certain cases; this is now fixed.
844
Thomas Heller47d7a062006-07-12 08:43:47 +0000845- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
846 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000847
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000848- Because of a misspelled preprocessor symbol, ctypes was always
849 compiled without thread support; this is now fixed.
850
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000851- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
852 methods now allow their database parameter to be None as the
853 sleepycat API allows.
854
Matt Flemingec926502006-07-28 11:27:27 +0000855- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
856 bluetooth API compared with Linux and FreeBSD.
857
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000858Tests
859-----
860
861- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
862 how long the test file should take to play. Now accepts taking 2.93 secs
863 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
864
Georg Brandl4793aa32006-07-28 18:31:39 +0000865- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
866 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
867 run via ``regrtest.py``. Now they do.

876
877- PythonLauncher now works correctly when the path to the script contains
878 characters that are treated specially by the shell (such as quotes).
879
880- Bug #1527397: PythonLauncher now launches scripts with the working directory
881 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000882 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000883 expect.

896
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000897- Bug #1501934: The scope of global variables that are locally assigned

Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000903- Bug #1417699: Reject locale-specific decimal point in float()
904 and atof().
905
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000906- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
907 omit a default "error" argument for NULL pointer. This allows
908 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000909
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000910- Bug #1519018: 'as' is now validated properly in import statements.
911
Neal Norwitz28746ab2006-07-09 22:14:42 +0000912- On 64 bit systems, int literals that use less than 64 bits are
913 now ints rather than longs.
914
Neal Norwitzed657552006-07-10 00:04:44 +0000915- Bug #1512814, Fix incorrect lineno's when code at module scope
916 started after line 256.
917
Tim Peters32a83612006-07-10 21:08:24 +0000918- New function ``sys._current_frames()`` returns a dict mapping thread
919 id to topmost thread stack frame. This is for expert use, and is
920 especially useful for debugging application deadlocks. The functionality
921 was previously available in Fazal Majid's ``threadframe`` extension
922 module, but it wasn't possible to do this in a wholly threadsafe way from
923 an extension.

943 be treated as the value they contain, instead.
944
Martin v. Löwisede77f52006-07-03 13:01:35 +0000945- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

970
Brett Cannon53ab5b72006-06-22 16:49:14 +0000971- Bug #1510580: The 'warnings' module improperly required that a Warning
972 category be either a types.ClassType and a subclass of Warning. The proper
973 check is just that it is a subclass with Warning as the documentation states.
974
Georg Brandlad29e632006-06-21 17:45:17 +0000975- The compiler module now correctly compiles the new try-except-finally
976 statement (bug #1509132).

Vinay Sajip28e57612006-07-01 10:45:20 +0000980- A bug was fixed in logging.config.fileConfig() which caused a crash on
981 shutdown when fileConfig() was called multiple times.
982
Gerhard Häring762fbd32006-07-02 17:48:30 +0000983- The sqlite3 module did cut off data from the SQLite database at the first
984 null character before sending it to a custom converter. This has been fixed
985 now.
986
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000987Extension Modules
988-----------------
989
Tim Peters112aad32006-07-19 00:03:19 +0000990- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
991 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
992 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000993
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000994- Assigning None to pointer type fields in ctypes structures possible
995 overwrote the wrong fields, this is fixed now.
996
997- Fixed a segfault in _ctypes when ctypes.wintypes were imported
998 on non-Windows platforms.
999
1000- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1001 integer or long, without range checking.
1002
1003- Patch #1517790: It is now possible to use custom objects in the ctypes
1004 foreign function argtypes sequence as long as they provide a from_param
1005 method, no longer is it required that the object is a ctypes type.
1006
1007- The '_ctypes' extension module now works when Python is configured
1008 with the --without-threads option.
1009
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001010- Bug #1513646: os.access on Windows now correctly determines write
1011 access, again.
1012
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001013- Bug #1512695: cPickle.loads could crash if it was interrupted with

1017 a CharacterDataHandler could crash the interpreter in pyexpat.
1018
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001019- Patch #1516912: improve Modules support for OpenVMS.

1022-----
1023
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001024- Automate Windows build process for the Win64 SSL module.
1025
Tim Peters32a83612006-07-10 21:08:24 +00001026- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001027 Previously, the slight difference could cause compilation errors of the
1028 'zlib' module on systems with more than one version of zlib.
1029
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001030- The MSI compileall step was fixed to also support a TARGETDIR
1031 with spaces in it.

1035
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001036- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001037 trying to be installed even though it's empty.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001060
1061Core and builtins
1062-----------------
1063
Georg Brandla56b9152006-06-19 06:35:54 +00001064- Patch #1507676: Error messages returned by invalid abstract object operations
1065 (such as iterating over an integer) have been improved and now include the
1066 type of the offending object to help with debugging.
1067
Brett Cannonea3912b2006-06-13 21:46:41 +00001068- Bug #992017: A classic class that defined a __coerce__() method that returned
1069 its arguments swapped would infinitely recurse and segfault the interpreter.
1070
Neal Norwitz909eb122006-06-12 02:13:21 +00001071- Fix the socket tests so they can be run concurrently.
1072
Neal Norwitzb9845e72006-06-12 02:11:18 +00001073- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001074 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001075
Brett Cannon22565aa2006-06-09 22:31:23 +00001076- Bug #532646: object.__call__() will continue looking for the __call__
1077 attribute on objects until one without one is found. This leads to recursion
1078 when you take a class and set its __call__ attribute to an instance of the
1079 class. Originally fixed for classic classes, but this fix is for new-style.
1080 Removes the infinite_rec_3 crasher.
1081
Georg Brandl24250812006-06-09 18:45:48 +00001082- The string and unicode methods startswith() and endswith() now accept
1083 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1084
Brett Cannonde3b0522006-06-08 17:00:45 +00001085- Buffer objects, at the C level, never used the char buffer
1086 implementation even when the char buffer for the wrapped object was
1087 explicitly requested (originally returned the read or write buffer).
1088 Now a TypeError is raised if the char buffer is not present but is
1089 requested.
1090
Georg Brandlddbaa662006-06-04 21:56:52 +00001091- Patch #1346214: Statements like "if 0: suite" are now again optimized
1092 away like they were in Python 2.4.
1093
Georg Brandlb7c8f542006-05-27 12:30:25 +00001094- Builtin exceptions are now full-blown new-style classes instead of
1095 instances pretending to be classes, which speeds up exception handling
1096 by about 80% in comparison to 2.5a2.
1097
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001098- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1099 Unicode 4.1.
1100
Georg Brandlf4ef1162006-05-26 18:03:31 +00001101- Patch #921466: sys.path_importer_cache is now used to cache valid and
1102 invalid file paths for the built-in import machinery which leads to
1103 fewer open calls on startup.
1104
Tim Peters696cf432006-05-24 21:10:40 +00001105- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1106 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1107 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1108 the number of input digits (it was and remains linear-time for bases
1109 2, 4, 8, 16 and 32).
1110
Tim Petersb713ec22006-05-23 18:45:30 +00001111- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1112 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1113 an integer close to ``sys.maxint``. This was repaired by patch
1114 #1335972, which also gives a nice speedup.
1115
Richard Jonescebbefc2006-05-23 18:28:17 +00001116- Patch #1337051: reduced size of frame objects.
1117
1118- PyErr_NewException now accepts a tuple of base classes as its
1119 "base" parameter.
1120
Richard Jones7c88dcc2006-05-23 10:37:38 +00001121- Patch #876206: function call speedup by retaining allocated frame
1122 objects.
1123
Georg Brandl7b90e162006-05-18 07:01:27 +00001124- Bug #1462152: file() now checks more thoroughly for invalid mode
1125 strings and removes a possible "U" before passing the mode to the
1126 C library function.
1127
Neal Norwitz1004a532006-05-15 07:17:23 +00001128- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1129
Neal Norwitz373f0a72006-05-15 07:04:36 +00001130- Bug #1487966: Fix SystemError with conditional expression in assignment
1131
Martin v. Löwis879768d2006-05-11 13:28:43 +00001132- WindowsError now has two error code attributes: errno, which carries
1133 the error values from errno.h, and winerror, which carries the error
1134 values from winerror.h. Previous versions put the winerror.h values
1135 (from GetLastError()) into the errno attribute.
1136
Martin v. Löwis77736712006-05-04 05:51:03 +00001137- Patch #1475845: Raise IndentationError for unexpected indent.
1138
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001139- Patch #1479181: split open() and file() from being aliases for each other.
1140
Tim Peters44bd9862006-06-01 13:49:23 +00001141- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1142 methods were always silently ignored by dictionaries when comparing keys.
1143 They are now passed through (except when using the C API function
1144 ``PyDict_GetItem()``, whose semantics did not change).
1145
1146- Bug #1456209: In some obscure cases it was possible for a class with a
1147 custom ``__eq__()`` method to confuse dict internals when class instances
1148 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1149 No, you don't have any code that did this ;-)

1157
Brett Cannon6ee7d012006-06-08 16:23:04 +00001158- Change binascii.hexlify to accept a read-only buffer instead of only a char
1159 buffer and actually follow its documentation.
1160
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001161- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1162
Nick Coghlanc649ec52006-05-29 12:43:05 +00001163- Patch #1478788 (modified version): The functional extension module has
1164 been renamed to _functools and a functools Python wrapper module added.
1165 This provides a home for additional function related utilities that are
1166 not specifically about functional programming. See PEP 309.
1167
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001168- Patch #1493701: performance enhancements for struct module.

1173 copy() method.
1174
Andrew MacIntyre92913322006-06-13 15:04:24 +00001175- Patch #1454481: thread stack size is now tunable at runtime for thread
1176 enabled builds on Windows and systems with Posix threads support.
1177
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001178- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1179 (up to the system limit of 32K characters).
1180
1181- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1182 As a result, these functions now raise WindowsError instead of OSError.
1183
Tim Peters7a822da2006-05-25 21:50:17 +00001184- ``time.clock()`` on Win64 should use the high-performance Windows
1185 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1186 Windows platforms).
1187
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001188- Calling Tk_Init twice is refused if the first call failed as that
1189 may deadlock.
1190
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001191- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1192 accept it without potentially using an uninitialized pointer.
1193
1194- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1195 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

Gregory P. Smith372b5832006-06-05 18:48:21 +00001201- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1202 parameter is supplied. [SF pybsddb bug #1477863]
1203
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001204- bsddb: the __len__ method of a DB object has been fixed to return correct
1205 results. It could previously incorrectly return 0 in some cases.
1206 Fixes SF bug 1493322 (pybsddb bug 1184012).
1207
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001208- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1209 aborts the db transaction safely when a modifier callback fails.
1210 Fixes SF python patch/bug #1408584.
1211
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001212- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001213 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001214 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1215 database calls that would previously deadlock. [SF python bug #775414]
1216
Vinay Sajip28e57612006-07-01 10:45:20 +00001217- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001218
Walter Dörwald4994d952006-06-19 08:07:50 +00001219- Patch #1506645: add Python wrappers for the curses functions

1239 mime.types file for determining MIME types.
1240
Georg Brandl2605ca82006-06-14 06:08:31 +00001241- Bug #1339007: Shelf objects now don't raise an exception in their
1242 __del__ method when initialization failed.
1243
Martin v. Löwisd8251432006-06-14 05:21:04 +00001244- Patch #1455898: The MBCS codec now supports the incremental mode for
1245 double-byte encodings.
1246
Tim Peters43898b42006-06-14 04:09:25 +00001247- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1248 guarantee that adjacent triples in the return list always describe
1249 non-adjacent blocks. Previously, a pair of matching blocks could end
1250 up being described by multiple adjacent triples that formed a partition
1251 of the matching pair.
1252
Greg Ward0e0c9f42006-06-11 16:24:11 +00001253- Bug #1498146: fix optparse to handle Unicode strings in option help,
1254 description, and epilog.
1255
Greg Wardd1c797e2006-06-11 14:42:41 +00001256- Bug #1366250: minor optparse documentation error.
1257
Greg Ward7f547402006-06-11 00:40:49 +00001258- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1259 clarify docs.
1260
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001261- The wsgiref package has been added to the standard library.
1262
Nick Coghlan676725d2006-06-08 13:54:49 +00001263- The functions update_wrapper() and wraps() have been added to the functools
1264 module. These make it easier to copy relevant metadata from the original
1265 function when writing wrapper functions.
1266
Tim Petersd6a9eef2006-06-05 01:48:21 +00001267- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1268 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001269
Martin v. Löwis3f767792006-06-04 19:36:28 +00001270- Patch #1359618: Speed up charmap encoder by using a trie structure
1271 for lookup.
1272
Tim Petersd609b1a2006-06-02 23:22:51 +00001273- The functions in the ``pprint`` module now sort dictionaries by key
1274 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1275 if and only if its display required more than one line, although that
1276 wasn't documented. The new behavior increases predictability; e.g.,
1277 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1278
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001279- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1280 (thanks for J. J. Lee).
1281
Georg Brandl2b330372006-05-28 20:23:12 +00001282- Patch #1496206: improve urllib2 handling of passwords with respect to
1283 default HTTP and HTTPS ports.
1284
George Yoshidaf3c65de2006-05-28 16:39:09 +00001285- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1286
Bob Ippolito7298f272006-05-23 18:43:47 +00001287- Patch #1281707: speed up gzip.readline.
1288
Georg Brandlb89316f2006-05-17 15:51:16 +00001289- Patch #1180296: Two new functions were added to the locale module:
1290 format_string() to get the effect of "format % items" but locale-aware,
1291 and currency() to format a monetary number with currency sign.
1292
Georg Brandle3a25832006-05-17 14:56:04 +00001293- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1294 and several features added, such as speed and geometry control.
1295
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001296- Patch #1488881: add support for external file objects in bz2 compressed
1297 tarfiles.
1298
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001299- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1300 stdout arguments, making it possible to redirect input and output
1301 for remote debugging.
1302
1303- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1304 a couple of issues, notably handling of long file names using the
1305 GNU LONGNAME extension.
1306
1307- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1308 new flag when ``name`` is already the name of an option flag.
1309
1310- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1311 package.
1312
1313- Patch #1472854: make the rlcompleter.Completer class usable on non-
1314 UNIX platforms.
1315
1316- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1317
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001318- Bug #1472827: correctly escape newlines and tabs in attribute values in
1319 the saxutils.XMLGenerator class.

1351
1352*Release date: 27-APR-2006*
1353
1354Core and builtins
1355-----------------
1356
Thomas Heller1b046642006-04-18 18:51:06 +00001357- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1358 by converting these apis from macros into exported functions again:
1359
1360 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1361 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1362 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1363 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1364 PyRun_String Py_CompileString
1365
Martin v. Löwis45294a92006-04-18 06:24:08 +00001366- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1367
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001368- All uses of PyStructSequence_InitType have been changed to initialize
1369 the type objects only once, even if the interpreter is initialized
1370 multiple times.
1371
Neal Norwitz61546162006-04-14 05:20:28 +00001372- Bug #1454485, array.array('u') could crash the interpreter. This was
1373 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1374 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1375
1376- Py_UNICODE is unsigned. It was always documented as unsigned, but
1377 due to a bug had a signed value in previous versions.
1378
Tim Peters3a5e8b12006-04-11 01:44:07 +00001379- Patch #837242: ``id()`` of any Python object always gives a positive
1380 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1381 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001382 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001383 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001384
Tim Peters3a5e8b12006-04-11 01:44:07 +00001385 def __hash__(self):
1386 return id(self) # WRONG
1387
1388 because a hash result must be a (short) Python int but it was always
1389 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001390 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001391 was always usable as a hash value before this patch. That's no longer
1392 necessarily so.
1393
1394- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001395 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001396 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001397 #1454844)
1398
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001399- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1400 involving generators that have paused outside of any ``try`` or ``with``
1401 blocks. (In 2.5a1, a paused generator that was part of a reference
1402 cycle could not be garbage collected, regardless of whether it was
1403 paused in a ``try`` or ``with`` block.)

1433 abusing errno.
1434
Tim Peters711bf302006-04-25 03:31:36 +00001435- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1436 a doctest to be skipped (the code is not run, and the expected output
1437 or exception is ignored).
1438
Nick Coghlanda2268f2006-04-24 04:37:15 +00001439- Fixed contextlib.nested to cope with exceptions being raised and
1440 caught inside exit handlers.
1441
Greg Wardab05edc2006-04-23 03:47:58 +00001442- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1443 hex, octal, or binary; add ``append_const`` action; keep going if
1444 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1445 added ``epilog`` for better help generation).
1446
Tim Peters21fbd572006-04-21 21:18:10 +00001447- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1448 called from a thread spawned as a side effect of importing a module.
1449
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001450- The pydoc module now supports documenting packages contained in
1451 .zip or .egg files.
1452
1453- The pkgutil module now has several new utility functions, such
1454 as ``walk_packages()`` to support working with packages that are either
1455 in the filesystem or zip files.
1456
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001457- The mailbox module can now modify and delete messages from
1458 mailboxes, in addition to simply reading them. Thanks to Gregory
1459 K. Johnson for writing the code, and to the 2005 Google Summer of
1460 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001461
Tim Petersc7605f22006-04-17 21:12:33 +00001462- The ``__del__`` method of class ``local`` in module ``_threading_local``
1463 returned before accomplishing any of its intended cleanup.
1464
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001465- Patch #790710: Add breakpoint command lists in pdb.

Martin v. Löwis10acfd02006-04-10 12:39:36 +00001503- Patch #1429775: Link extension modules with the shared libpython.
1504
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001505- Fixed a libffi build problem on MIPS systems.
1506
Tim Peters8931ff12006-05-13 23:28:20 +00001507- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1508 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1509 and "%zu" for unsigned integers of type ``size_t``.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001511Tests
1512-----
1513
Nick Coghlanda2268f2006-04-24 04:37:15 +00001514- test_contextlib now checks contextlib.nested can cope with exceptions
1515 being raised and caught inside exit handlers.
1516
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001517- test_cmd_line now checks operation of the -m and -c command switches
1518
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001519- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1520 it separately and by hand. It also wasn't cleaning up its changes to
1521 the current Decimal context.
1522
Thomas Woutersabd08882006-04-26 15:53:30 +00001523- regrtest.py now has a -M option to run tests that test the new limits of
1524 containers, on 64-bit architectures. Running these tests is only sensible
1525 on 64-bit machines with more than two gigabytes of memory. The argument
1526 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001534Documentation
1535-------------
1536
Tim Petersb06d28c2006-05-12 01:57:59 +00001537- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1538
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001539- PEP 343: Added Context Types section to the library reference
1540 and attempted to bring other PEP 343 related documentation into
1541 line with the implementation and/or python-dev discussions.
1542
Tim Peters8dc73d22006-04-24 02:03:16 +00001543- Bug #1337990: clarified that ``doctest`` does not support examples
1544 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001547What's New in Python 2.5 alpha 1?
1548=================================
1549
Anthony Baxterebed3f62006-04-03 15:03:44 +00001550*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001551
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001552Core and builtins
1553-----------------
1554
Nick Coghlan43832302006-04-23 17:04:07 +00001555- PEP 338: -m command line switch now delegates to runpy.run_module
1556 allowing it to support modules in packages and zipfiles
1557
Martin v. Löwisc661b882006-04-20 04:54:23 +00001558- On Windows, .DLL is not an accepted file name extension for
1559 extension modules anymore; extensions are only found if they
1560 end in .PYD.
1561
Martin v. Löwisea62d252006-04-03 10:56:49 +00001562- Bug #1421664: sys.stderr.encoding is now set to the same value as
1563 sys.stdout.encoding.
1564
Neal Norwitz92e212f2006-04-03 04:48:37 +00001565- __import__ accepts keyword arguments.
1566
Georg Brandlccadf842006-03-31 18:54:53 +00001567- Patch #1460496: round() now accepts keyword arguments.
1568
Anthony Baxter262c00a2006-03-30 10:53:17 +00001569- Fixed bug #1459029 - unicode reprs were double-escaped.
1570
Hye-Shik Changd478f342006-03-23 12:32:36 +00001571- Patch #1396919: The system scope threads are reenabled on FreeBSD
1572 5.4 and later versions.
1573
Neal Norwitze98ccf62006-03-23 05:39:47 +00001574- Bug #1115379: Compiling a Unicode string with an encoding declaration
1575 now gives a SyntaxError.
1576
Georg Brandlabd1ff82006-03-18 07:59:59 +00001577- Previously, Python code had no easy way to access the contents of a
1578 cell object. Now, a ``cell_contents`` attribute has been added
1579 (closes patch #1170323).
1580
Tim Peterscf79aac2006-03-16 01:14:46 +00001581- Patch #1123430: Python's small-object allocator now returns an arena to
1582 the system ``free()`` when all memory within an arena becomes unused
1583 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1584 freed. Some applications will see a drop in virtual memory size now,
1585 especially long-running applications that, from time to time, temporarily
1586 use a large number of small objects. Note that when Python returns an
1587 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001588 platform C library will in turn return that memory to the operating system.
1589 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001590 appears to be effective at least on Microsoft C and gcc-based systems.
1591 Thanks to Evan Jones for hard work and patience.
1592
Georg Brandl533ff6f2006-03-08 18:09:27 +00001593- Patch #1434038: property() now uses the getter's docstring if there is
1594 no "doc" argument given. This makes it possible to legitimately use
1595 property() as a decorator to produce a read-only property.
1596
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001597- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1598 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1599 of requiring an int or long in slicing and a few other contexts, enabling
1600 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1601
Neal Norwitz995acdf2006-03-07 05:01:00 +00001602- Fixed various bugs reported by Coverity's Prevent tool.
1603
Brett Cannonbf364092006-03-01 04:25:17 +00001604- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1605 new exception base class, BaseException, which has a new message attribute.
1606 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1607 Raising a string exception now raises a DeprecationWarning.
1608
Thomas Woutersfb609f42006-02-28 16:37:25 +00001609- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1610 explicitly relative, using 'from .module import name' to mean 'from the same
1611 package as this module is in. Imports without dots still default to the
1612 old relative-then-absolute, unless 'from __future__ import
1613 absolute_import' is used.
1614
Brett Cannona7446e32006-02-27 23:39:10 +00001615- Properly check if 'warnings' raises an exception (usually when a filter set
1616 to "error" is triggered) when raising a warning for raising string
1617 exceptions.
1618
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001619- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001620 The name was removed from Include/code.h.
1621
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001622- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001623
Guido van Rossum1968ad32006-02-25 22:38:04 +00001624- Patch 1433928:
1625 - The copy module now "copies" function objects (as atomic objects).
1626 - dict.__getitem__ now looks for a __missing__ hook before raising
1627 KeyError.
1628
Tim Peters84ef21c2006-02-28 20:39:06 +00001629- PEP 343: with statement implemented. Needs ``from __future__ import
1630 with_statement``. Use of 'with' as a variable will generate a warning.
1631 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001632 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001633 The following objects have __context__ methods:
1634 - The built-in file type.
1635 - The thread.LockType type.
1636 - The following types defined by the threading module:
1637 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1638 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001639
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001640- Fix the encodings package codec search function to only search
1641 inside its own package. Fixes problem reported in patch #1433198.
1642
1643 Note: Codec packages should implement and register their own
1644 codec search function. PEP 100 has the details.
1645
Tim Peters9ea89d22006-06-04 03:26:02 +00001646- PEP 353: Using ``Py_ssize_t`` as the index type.
1647
1648- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1649 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1650 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1651 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1652 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001653
Neal Norwitzfc76d632006-01-10 06:03:13 +00001654- Patch #1400181, fix unicode string formatting to not use the locale.
1655 This is how string objects work. u'%f' could use , instead of .
1656 for the decimal point. Now both strings and unicode always use periods.
1657
Neal Norwitz671b9e32006-01-09 07:07:12 +00001658- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1659 configure would break checking curses.h.
1660
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001661- Bug #959576: The pwd module is now builtin. This allows Python to be
1662 built on UNIX platforms without $HOME set.
1663
Neal Norwitzc10978f2005-12-19 06:07:16 +00001664- Bug #1072182, fix some potential problems if characters are signed.
1665
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001666- Bug #889500, fix line number on SyntaxWarning for global declarations.
1667
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001668- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1669
Neal Norwitze7214a12005-12-18 05:03:17 +00001670- Support for converting hex strings to floats no longer works.
1671 This was not portable. float('0x3') now raises a ValueError.
1672
Barry Warsaw2a38a862005-12-18 01:27:35 +00001673- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001674 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001675 is now displayed in interactive prompt banner.
1676
Georg Brandlfa166682005-12-17 21:45:17 +00001677- Implementation of PEP 341 - Unification of try/except and try/finally.
1678 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001679 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001680
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001681- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1682 now encodes backslash correctly.
1683
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001684- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1685
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001686- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001687 and long longs.
1688
Neal Norwitz67715f02005-11-09 06:59:35 +00001689- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001690 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001691 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001692
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001693- Replaced most Unicode charmap codecs with new ones using the
1694 new Unicode translate string feature in the builtin charmap
1695 codec; the codecs were created from the mapping tables available
1696 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1697 encodings now include a mapping for the Apple logo)
1698
Tim Peterse3547fd2005-12-16 23:13:57 +00001699- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001700
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001701- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001702
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001703- A new AST parser implementation was completed. The abstract
1704 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001705 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001706
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001707- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001708 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1709
Neal Norwitz708e51a2005-10-03 04:48:15 +00001710- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1711
Neal Norwitz11bd1192005-10-03 00:54:56 +00001712- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1713 Provide a warning when a directory is passed on the command line.
1714
Neal Norwitz40d37812005-10-02 01:48:49 +00001715- Fix segfault with invalid coding.
1716
1717- SF bug #772896: unknown encoding results in MemoryError.
1718
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001719- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001720 supported a __len__() method which evaluated to False when the iterator
1721 was empty.
1722
Guido van Rossum630db602005-09-20 18:49:54 +00001723- On 64-bit platforms, when __len__() returns a value that cannot be
1724 represented as a C int, raise OverflowError.
1725
Skip Montanarof8948ca2005-09-19 03:54:46 +00001726- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001727 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001728
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001729- SF bug #893549: parsing keyword arguments was broken with a few format
1730 codes.
1731
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001732- Changes donated by Elemental Security to make it work on AIX 5.3
1733 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1734 bug #105470: test_pwd fails on 64bit system (Opteron).
1735
Guido van Rossum539c6622005-09-14 17:49:54 +00001736- Changes donated by Elemental Security to make it work on HP-UX 11 on
1737 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1738
Georg Brandl4550b8d2005-08-26 06:43:52 +00001739- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001740 (fixes bug #1119418).
1741
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001742- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1743
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001744- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1745 exceptions that cause a function to exit.
1746
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001747- The implementation of set() and frozenset() was revised to use its
1748 own internal data structure. Memory consumption is reduced by 1/3
1749 and there are modest speed-ups as well. The API is unchanged.
1750
Tim Petersde7990b2005-07-17 23:45:23 +00001751- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1752
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001753- SF bug #1229429: PyObject_CallMethod failed to decrement some
1754 reference counts in some error exit cases.
1755
Tim Petersecc6e6a2005-07-10 22:30:55 +00001756- SF bug #1185883: Python's small-object memory allocator took over
1757 a block managed by the platform C library whenever a realloc specified
1758 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001759 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001760 portable way to copy data from the C-managed block into Python's
1761 small-object space without risking a memory fault. Python's small-object
1762 realloc now leaves such blocks under the control of the platform C
1763 realloc.
1764
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001765- SF bug #1232517: An overflow error was not detected properly when
1766 attempting to convert a large float to an int in os.utime().
1767
Raymond Hettinger3296e692005-06-29 23:29:56 +00001768- SF bug #1224347: hex longs now print with lowercase letters just
1769 like their int counterparts.
1770
Michael W. Hudson188d4362005-06-20 16:52:57 +00001771- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1772 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1773 interpreter states; back out that fix and do a better job (see
1774 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1775 for a longer write-up of the problem).
1776
Michael W. Hudsondf888462005-06-03 14:41:55 +00001777- SF patch #1180995: marshal now uses a binary format by default when
1778 serializing floats.
1779
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001780- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1781 the routines that promise to produce IEEE 754 binary representations
1782 of floats now simply copy bytes around.
1783
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001784- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1785 278.
1786
Brett Cannonc3647ac2005-04-26 03:45:26 +00001787- patch #1109424: int, long, float, complex, and unicode now check for the
1788 proper magic slot for type conversions when subclassed. Previously the
1789 magic slot was ignored during conversion. Semantics now match the way
1790 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001791 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001792 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001793 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001794
Barry Warsawc8d907c2005-04-19 23:43:40 +00001795- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1796 NULL, now raise an AttributeError when attempting to set or delete the
1797 attribute. Previously a TypeError was raised, but this was inconsistent
1798 with the equivalent pure-Python implementation.
1799
Michael W. Hudson774479c2005-04-18 08:46:17 +00001800- It is now safe to call PyGILState_Release() before
1801 PyEval_InitThreads() (note that if there is reason to believe there
1802 are multiple threads around you still must call PyEval_InitThreads()
1803 before using the Python API; this fix is for extension modules that
1804 have no way of knowing if Python is multi-threaded yet).
1805
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001806- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1807 disabled caused a crash.
1808
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001809- Bug #1165306: instancemethod_new allowed the creation of a method
1810 with im_class == im_self == NULL, which caused a crash when called.
1811
Tim Petersecc6e6a2005-07-10 22:30:55 +00001812- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001813 fixes the crash seen in bug #1165761
1814
Raymond Hettinger96229b12005-03-11 06:49:40 +00001815- Added two new builtins, any() and all().
1816
Brett Cannon409d8f22005-03-05 06:47:57 +00001817- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001818 (e.g., ``class C(): pass`` is no longer a syntax error).
1819 Patch #1176012 added support to the 'parser' module and 'compiler' package
1820 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001821
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001822- Patch #1115086: Support PY_LONGLONG in structmember.
1823
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001824- Bug #1155938: new style classes did not check that __init__() was
1825 returning None.
1826
Tim Petersecc6e6a2005-07-10 22:30:55 +00001827- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001828 ('\') with a specific error message.
1829
Martin v. Löwisff232d72005-03-03 09:24:38 +00001830- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1831
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001832- Bug #1124295: the __name__ attribute of file objects was
1833 inadvertently made inaccessible in restricted mode.
1834
Tim Petersecc6e6a2005-07-10 22:30:55 +00001835- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001836 an ferror() call.
1837
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001838- min() and max() now support key= arguments with the same meaning as in
1839 list.sort().
1840
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001841- The peephole optimizer now performs simple constant folding in expressions:
1842 (2+3) --> (5).
1843
Raymond Hettingera422c342005-01-11 03:03:27 +00001844- set and frozenset objects can now be marshalled. SF #1098985.
1845
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001846- Bug #1077106: Poor argument checking could cause memory corruption
1847 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001848
Jeremy Hyltonab630502005-02-04 18:44:06 +00001849- The parser did not complain about future statements in illegal
1850 positions. It once again reports a syntax error if a future
1851 statement occurs after anything other than a doc string.
1852
Neil Schemenauercf52c072005-08-12 17:34:58 +00001853- Change the %s format specifier for str objects so that it returns a
1854 unicode instance if the argument is not an instance of basestring and
1855 calling __str__ on the argument returns a unicode instance.
1856
Tim Petersf4e69282006-02-27 17:15:31 +00001857- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1858 current thread state when the auto-GIL-state machinery knows about
1859 it (since the thread state is being deleted, continuing to remember it
1860 can't help, but can hurt if another thread happens to get created with
1861 the same thread id).
1862

1891 for applications that require this specific version (such as IDNA).
1892
Neal Norwitzb62c4332006-03-04 18:35:47 +00001893- The timing module is no longer built by default. It was deprecated

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002053- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2054 been renamed to have only a single underscore prefix. This was done to
2055 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002056
Nick Coghlan43832302006-04-23 17:04:07 +00002057- PEP 338: new module runpy defines a run_module function to support
2058 executing modules which provide access to source code or a code object
2059 via the PEP 302 import mechanisms.
2060
Anthony Baxter93f5b932006-04-03 08:05:07 +00002061- The email module's parsedate_tz function now sets the daylight savings

2069 in attribute values.
2070
Anthony Baxterc51ee692006-04-01 00:57:31 +00002071- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002072 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002073 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002074 module will not be built.
2075
Tim Petersc17976e2006-04-01 00:26:53 +00002076- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2077 aren't officially supported here, and trying to use them will probably
2078 raise an exception some day. But dicts have been allowed, and "mostly
2079 worked", so support for them won't go away without warning.
2080
Georg Brandl338ef7d2006-03-31 18:42:16 +00002081- Bug #1445068: getpass.getpass() can now be given an explicit stream
2082 argument to specify where to write the prompt.
2083

2099
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002100- email 4.0 package now integrated. This is largely the same as the email 3.0
2101 package that was included in Python 2.3, except that PEP 8 module names are
2102 now used (e.g. mail.message instead of email.Message). The MIME classes
2103 have been moved to a subpackage (e.g. email.mime.text instead of
2104 email.MIMEText). The old names are still supported for now. Several
2105 deprecated Message methods have been removed and lots of bugs have been
2106 fixed. More details can be found in the email package documentation.
2107
Walter Dörwald40108c92006-03-27 08:15:44 +00002108- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2109 (a subclass of tuple) that provides incremental decoders and encoders
2110 (a way to use stateful codecs without the stream API). Python functions
2111 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2112 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2113 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002114
Walter Dörwald067db482006-03-15 22:17:27 +00002115- Patch #1359365: Calling next() on a closed StringIO.String object raises
2116 a ValueError instead of a StopIteration now (like file and cString.String do).
2117 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2118 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002119
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002120- A regrtest option -w was added to re-run failed tests in verbose mode.

Tim Peterse3547fd2005-12-16 23:13:57 +00002192 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2193 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2194 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2195 Ronald L. Rivest offered this advice for Python:
2196
2197 "The consensus of researchers in this area (at least as
2198 expressed at the NIST Hash Function Workshop 10/31/05),
2199 is that SHA-256 is a good choice for the time being, but
2200 that research should continue, and other alternatives may
2201 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002202
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002203- Added a subset of Fredrik Lundh's ElementTree package. Available

Raymond Hettinger68c04532005-06-10 11:05:19 +00002300 the generate_tokens() function now accepts a callable argument that
2301 terminates by raising StopIteration.
2302
Georg Brandl9166e1a2005-06-04 09:20:03 +00002303- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2304
Georg Brandl268e61c2005-06-03 14:28:50 +00002305- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2306 component of the path.
2307
Skip Montanaro174dd222005-05-14 20:54:16 +00002308- Patch #1120353: The xmlrpclib module provides better, more transparent,
2309 support for datetime.{datetime,date,time} objects. With use_datetime set
2310 to True, applications shouldn't have to fiddle with the DateTime wrapper
2311 class at all.
2312
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002313- distutils.commands.upload was added to support uploading distribution
2314 files to PyPI.
2315
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002316- distutils.commands.register now encodes the data as UTF-8 before posting
2317 them to PyPI.
2318
Raymond Hettinger267b8682005-03-27 10:47:39 +00002319- decimal operator and comparison methods now return NotImplemented
2320 instead of raising a TypeError when interacting with other types. This
2321 allows other classes to implement __radd__ style methods and have them
2322 work as expected.
2323
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002324- Bug #1163325: Decimal infinities failed to hash. Attempting to
2325 hash a NaN raised an InvalidOperation instead of a TypeError.
2326
Tim Petersecc6e6a2005-07-10 22:30:55 +00002327- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002328 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2329
Martin v. Löwis00a73e72005-03-04 19:40:34 +00002330- Patch #1043890: Add extractall method to tarfile.
2331
Martin v. Löwisc72dd382005-03-04 13:50:17 +00002332- Patch #1075887: Don't require MSVC in distutils if there is nothing
2333 to build.
2334
Martin v. Löwis637431b2005-03-03 23:12:42 +00002335- Patch #1103407: Properly deal with tarfile iterators when untarring
2336 symbolic links on Windows.
2337
Tim Petersecc6e6a2005-07-10 22:30:55 +00002338- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +00002339 profile.py if available.
2340
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00002341- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
2342
Martin v. Löwisc5574e82005-03-03 10:57:37 +00002343- Patch #1117454: Remove code to special-case cookies without values
2344 in LWPCookieJar.
2345
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00002346- Patch #1117339: Add cookielib special name tests.
2347
Martin v. Löwise869eb12005-03-03 09:46:07 +00002348- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
2349
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00002350- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
2351
Martin v. Löwisdf241532005-03-03 08:17:42 +00002352- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
2353
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00002354- Patch #1104111: Alter setup.py --help and --help-commands.
2355
Martin v. Löwis4afe1542005-03-01 08:09:28 +00002356- Patch #1121234: Properly cleanup _exit and tkerror commands.
2357
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00002358- Patch #1049151: xdrlib now unpacks booleans as True or False.
2359
Raymond Hettingerbab41432005-02-05 01:31:19 +00002360- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2361
Guido van Rossumd0641422005-02-03 15:01:24 +00002362- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2363 disables recursive traversal through instance attributes, which can
2364 be exploited in various ways.
2365
Tim Peterse3547fd2005-12-16 23:13:57 +00002366- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002367 flags on the HTTP listening socket.
2368
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002369- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2370 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2371
Fred Drakefbdeaad2006-07-29 16:56:15 +00002372- Patches #893642, #1039083: add allow_none, encoding arguments to
2373 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002374
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002375- Bug #1110478: Revert os.environ.update to do putenv again.
2376
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002377- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2378
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002379- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2380
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002381- Enhancements to the csv module:
2382
2383 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002384 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002385 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002386 + Dialect parameter parsing has been re-implemented to improve error
2387 reporting.
2388 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2389 dictates.
2390 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002391 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002392 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002393 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2394 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002395 + reader now allows \r characters to be quoted (previously it only allowed
2396 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002397 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002398 + Dialect classes passed to the module are no longer instantiated by
2399 the module before being parsed (the former validation scheme required
2400 this, but the mechanism was unreliable).
2401 + The dialect registry now contains instances of the internal
2402 C-coded dialect type, rather than references to python objects.
2403 + the internal c-coded dialect type is now immutable.
2404 + register_dialect now accepts the same keyword dialect specifications
2405 as the reader and writer, allowing the user to register dialects
2406 without first creating a dialect class.
2407 + a configurable limit to the size of parsed fields has been added -
2408 previously, an unmatched quote character could result in the entire
2409 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002410 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002411 the parser field size limit (returning the former limit). The initial
2412 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002413 + A line_num attribute has been added to the reader object, which tracks
2414 the number of lines read from the source iterator. This is not
2415 the same as the number of records returned, as records can span
2416 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002417 + reader and writer objects were not being registered with the cyclic-GC.
2418 This has been fixed.
2419
Brett Cannone6539c42005-01-08 02:43:53 +00002420- _DummyThread objects in the threading module now delete self.__block that is
2421 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2422 lock primitives tend to be limited in number and thus should not be wasted on
2423 a _DummyThread object. Fixes bug #1089632.
2424
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002425- The imghdr module now detects Exif files.
2426
Raymond Hettinger6065d322004-12-20 23:51:53 +00002427- StringIO.truncate() now correctly adjusts the size attribute.
2428 (Bug #951915).
2429
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002430- locale.py now uses an updated locale alias table (built using
2431 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2432 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002433 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002434
Raymond Hettinger3557f422004-12-07 12:02:02 +00002435- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2436
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002437- the pickle module no longer accepts the deprecated None option in the
2438 args tuple returned by __reduce__().
2439
Brett Cannon84667c02004-12-07 03:25:18 +00002440- optparse now optionally imports gettext. This allows its use in setup.py.
2441
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002442- the pickle module no longer uses the deprecated bin parameter.
2443
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002444- the shelve module no longer uses the deprecated binary parameter.
2445
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002446- the pstats module no longer uses the deprecated ignore() method.
2447
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002448- the filecmp module no longer uses the deprecated use_statcache argument.
2449
Raymond Hettinger664347b2004-12-04 21:21:53 +00002450- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2451 extended or overridden by subclasses. Formerly, the subclassed method would
2452 be ignored by the rest of the module. (Bug #1078905).
2453
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002454- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002455 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002456
Walter Dörwald36733692004-12-22 12:50:50 +00002457- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2458 once when a size argument is given. This prevents a buffer overflow in the
2459 tokenizer with very long source lines.
2460
Barry Warsaw538561e2006-01-01 21:48:54 +00002461- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2462 immediately after creating the object, without any intervening
2463 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002464
Skip Montanaro05885812005-01-16 20:48:27 +00002465- The reconvert.quote function can now emit triple-quoted strings. The
2466 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002467
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002468- ``UserString.MutableString`` now supports negative indices in
2469 ``__setitem__`` and ``__delitem__``
2470
Greg Ward40407942005-03-05 02:53:17 +00002471- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2472 correctly.
2473
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002474- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2475 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2476 character even if the user has passed a size parameter to get a proper
2477 line ending. Remove the special handling of a "\r\n" that has been split
2478 between two lines.
2479
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002480- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2481 about illegal code points. The codec now supports PEP 293 style error
2482 handlers.
2483
Walter Dörwald78a78b02005-09-01 12:04:29 +00002484- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002485 from the input stream, so that the output is a byte string in the correct
2486 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002487
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002488- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2489 considering it exactly like a '*'.
2490
Walter Dörwald007f8df2005-10-09 19:42:27 +00002491- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2492 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002493
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002494- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2495
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002496- Patch #1413711: Certain patterns of differences were making difflib
2497 touch the recursion limit.
2498
Walter Dörwald58917a62006-03-31 15:26:22 +00002499- Bug #947906: An object oriented interface has been added to the calendar
2500 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002501 called as a script (e.g. via ``python -mcalendar``). Localized month and
2502 weekday names can be ouput (even if an exotic encoding is used) using
2503 special classes that use unicode.

2512
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002513- Build support for Win64-AMD64 was added.
2514
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002515- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2516
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002517- Patch #881820: look for openpty and forkpty also in libbsd.
2518
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002519- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2520 The zlib module is now builtin on Windows.
2521
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002522- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2523
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002524- Bug #1189330: configure did not correctly determine the necessary
2525 value of LINKCC if python was built with GCC 4.0.
2526
Trent Mick8321b422005-07-26 02:29:21 +00002527- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2528 vulnerability in zlib 1.2.1 and 1.2.2.
2529
Brett Cannon08cd5982005-04-24 22:26:38 +00002530- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2531 flags that change binary compatibility. Changes were also made to
2532 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002533 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002534
Bob Ippolitoed233462005-03-29 13:47:59 +00002535- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2536 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2537 no longer exists). This configure patch makes things right.
2538
Martin v. Löwise2713be2005-03-08 15:03:08 +00002539- Bug #1158607: Build with --disable-unicode again.
2540
Brett Cannon46d96232005-02-16 00:07:19 +00002541- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2542 defined. Discovered as a result of not being able to build on OS X.
2543
Brett Cannon516592f2004-12-07 00:42:59 +00002544- setup.py now uses the directories specified in LDFLAGS using the -L option
2545 and in CPPFLAGS using the -I option for adding library and include
2546 directories, respectively, for compiling extension modules against. This has
2547 led to the core being compiled using the values in CPPFLAGS. It also removes
2548 the need for the special-casing of both DarwinPorts and Fink for darwin since
2549 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2550 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2551 Fink, ``-I/opt/local/include`` for DarwinPorts).
2552
Brett Cannon43802422005-02-10 20:48:03 +00002553- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2554 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2555 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2556 Closes bug #1096244. Thanks Gregory Bond.

Tim Petersc9d78aa2006-03-26 23:27:58 +00002561- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2562 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2563 is obtained via the ``PyObject_`` family, it must be released via the
2564 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2565 always been officially true, but when Python's small-object allocator was
2566 introduced, an attempt was made to cater to a few extension modules
2567 discovered at the time that obtained memory via ``PyObject_New`` but
2568 released it via ``PyMem_DEL``. It's years later, and if such code still
2569 exists it will fail now (probably with segfaults, but calling wrong
2570 low-level memory management functions can yield many symptoms).

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002576- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2577 mapping argument now. This string is used as a mapping table. Byte values
2578 greater than the length of the string and 0xFFFE are treated as undefined
2579 mappings.
