295 a filename clash instead of possibly losing a message. (Patch by David
296 Watson.)
297
Andrew M. Kuchlingbb876b92006-11-10 13:08:03 +0000298- Patch #1514544: mailbox.py: Try to ensure that messages/indexes have

Andrew M. Kuchling830358a2006-11-17 16:16:28 +0000302- mailbox.py: Change MH.pack() to not lock individual message files; this

Neal Norwitz0bcafac2006-09-11 08:51:17 +0000376- Make _PyGILState_NoteThreadState() static, it was not used anywhere
377 outside of pystate.c and should not be necessary.
378
Brett Cannon19d76c52006-09-09 07:18:44 +0000379- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
380 allows calling unicode() on exceptions classes directly to succeed.

398 head is the original string if sep was not found.
399
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000400- Bug #1520864: unpacking singleton tuples in list comprehensions and
401 generator expressions (x for x, in ... ) works again. Fixing this problem
402 required changing the .pyc magic number. This means that .pyc files
403 generated before 2.5c2 will be regenerated.

508
Neal Norwitz24b6f202006-09-05 04:43:56 +0000509- Fix infinite recursion when subclassing long and overriding __hash__.
510
511- Fix concatenation (+=) of long strings.
512
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000513- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000514 compared equal or unequal to a string and a UnicodeDecodeError
515 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000516
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000517 Instead, the equal (==) and unequal (!=) comparison operators will
518 now issue a UnicodeWarning and interpret the two objects as
519 unequal. The UnicodeWarning can be filtered as desired using
520 the warning framework, e.g. silenced completely, turned into an
521 exception, logged, etc.
522
523 Note that compare operators other than equal and unequal will still
524 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000525
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000526- Fix segfault when doing string formatting on subclasses of long.

530
531- Fix bug related to __len__ functions returning negative values with
532 classic classes.
533
534- Patch #1538606, Fix __index__() clipping. There were some problems
535 discovered with the API and how integers that didn't fit into Py_ssize_t
536 were handled. This patch attempts to provide enough alternatives
537 to effectively use __index__.
538
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000539- Bug #1536021: __hash__ may now return long int; the final hash
540 value is obtained by invoking hash on the long int.
541
Thomas Hellerab1049c2006-08-08 17:37:00 +0000542- Bug #1536786: buffer comparison could emit a RuntimeWarning.

545 sys.stdin is closed.
546
Thomas Heller74d36f02006-08-04 18:17:40 +0000547- On Windows, the PyErr_Warn function is now exported from
548 the Python dll again.
549
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000550- Bug #1191458: tracing over for loops now produces a line event
551 on each iteration. Fixing this problem required changing the .pyc
552 magic number. This means that .pyc files generated before 2.5c1
553 will be regenerated.
554
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000555- Bug #1333982: string/number constants were inappropriately stored
556 in the byte code and co_consts even if they were not used, ie
557 immediately popped off the stack.
558
Georg Brandle9462c72006-08-04 18:03:37 +0000559- Fixed a reference-counting problem in property().

564
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000565- Fix a bug in the ``compiler`` package that caused invalid code to be
566 generated for generator expressions.
567
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000568- The distutils version has been changed to 2.5.0. The change to
569 keep it programmatically in sync with the Python version running
570 the code (introduced in 2.5b3) has been reverted. It will continue
571 to be maintained manually as static string literal.
572
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000573- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000574 and this cannot be converted to the required C type, an exception is
575 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000576 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000577
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000578- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000579 an exception.
580
Tim Peterscbdd3502006-09-05 01:47:53 +0000581- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000582 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000583 workarounds for clocks with low resolution, to stop the code yielding
584 duplicate UUIDs.
585
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000586- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
587 before raising SystemExit, allowing IDLE to honor quit() and exit().
588
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000589- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.

622
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000623- Bug #1530559, struct.pack raises TypeError where it used to convert.

Fred Drake53912162006-07-29 13:22:49 +0000670What's New in Python 2.5 beta 3?
671================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000672
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000673*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000674
675Core and builtins
676-----------------
677
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000678- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000679 returned a long (see PEP 353).
680
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000681- Bug #1515471: string.replace() accepts character buffers again.
682
Neal Norwitz07aadb12006-07-30 06:55:48 +0000683- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
684 This provides the proper warning for struct.pack().
685 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
686
Neal Norwitz0d62a062006-07-30 06:53:31 +0000687- Patch #1531113: Fix augmented assignment with yield expressions.
688 Also fix a SystemError when trying to assign to yield expressions.
689
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000690- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
691 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
692 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
693 excessive filesystem operations during imports.
694
Tim Petersbc24eee2006-07-27 01:14:53 +0000695- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
696 operations on signed longs that are formally undefined by C.
697 Unfortunately, at least one compiler now cares about that, so complicated
698 the code to make that compiler happy again.
699
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000700- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
701
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000702- Patch #1232023: Stop including current directory in search
703 path on Windows.
704
Neal Norwitze1fdb322006-07-21 05:32:28 +0000705- Fix some potential crashes found with failmalloc.
706
Neal Norwitze7563102006-07-17 01:00:16 +0000707- Fix warnings reported by Klocwork's static analysis tool.
708
Neal Norwitz84be93b2006-07-16 01:50:38 +0000709- Bug #1512814, Fix incorrect lineno's when code within a function
710 had more than 255 blank lines.
711
Georg Brandl9dceedb2006-07-12 15:31:17 +0000712- Patch #1521179: Python now accepts the standard options ``--help`` and
713 ``--version`` as well as ``/?`` on Windows.
714
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000715- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000716 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000717 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000718
Tim Peters112aad32006-07-19 00:03:19 +0000719- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000720 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000721 new ``sys._current_frames()`` returns a dictionary with one entry,
722 mapping the faux "thread id" 0 to the current frame.
723
Ronald Oussoren3075e162006-07-25 20:28:55 +0000724- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000725
Ronald Oussoren3075e162006-07-25 20:28:55 +0000726
Neal Norwitza1f10902006-07-12 07:28:29 +0000727Library
728-------
729
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000730- Correction of patch #1455898: In the mbcs decoder, set final=False
731 for stream decoder, but final=True for the decode function.
732
Georg Brandl07fec3a2006-08-01 18:49:24 +0000733- os.urandom no longer masks unrelated exceptions like SystemExit or
734 KeyboardInterrupt.
735
Tim Peters4643c2f2006-08-10 22:45:34 +0000736- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000737 shutil.copytree on Windows
738
Georg Brandle34ac7c2006-07-30 11:07:23 +0000739- Bug #1002398: The documentation for os.path.sameopenfile now correctly
740 refers to file descriptors, not file objects.
741
Tim Peterscbdd3502006-09-05 01:47:53 +0000742- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000743 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000744 #1513611, and probably others.
745
Georg Brandledd9b0d2006-07-29 09:33:26 +0000746- Bug #1441397: The compiler module now recognizes module and function
747 docstrings correctly as it did in Python 2.4.
748
Tim Peters6f681472006-07-27 23:44:37 +0000749- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
750 lost that tests are sorted by name before being run. This rarely
751 matters for well-written tests, but can create baffling symptoms if
752 side effects from one test to the next affect outcomes. ``DocTestFinder``
753 has been changed to sort the list of tests it returns.
754
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000755- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000756 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000757
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000758- Bug #978833: Really close underlying socket in _socketobject.close.
759
Georg Brandldb232dc2006-08-20 13:15:43 +0000760- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
761 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000762
Georg Brandlcf0c1722006-07-26 07:23:32 +0000763- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
764 to recursive calls and call it with the failing package name.
765
Martin v. Löwis0b483032006-07-25 09:53:12 +0000766- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
767
Georg Brandlc13c34c2006-07-24 14:09:56 +0000768- Patch #1515343: Fix printing of deprecated string exceptions with a
769 value in the traceback module.
770
Greg Ward48fae7a2006-07-23 16:05:51 +0000771- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
772
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000773- Patch #1524429: Use repr() instead of backticks in Tkinter again.
774
Brett Cannoncaebe222006-07-18 04:41:36 +0000775- Bug #1520914: Change time.strftime() to accept a zero for any position in its
776 argument tuple. For arguments where zero is illegal, the value is forced to
777 the minimum value that is correct. This is to support an undocumented but
778 common way people used to fill in inconsequential information in the time
779 tuple pre-2.4.
780
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000781- Patch #1220874: Update the binhex module for Mach-O.
782
Barry Warsawb110bad2006-07-21 14:51:07 +0000783- The email package has improved RFC 2231 support, specifically for
784 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
785 (name*0=<blah>) parameter continuations. This may change the types of
786 values returned from email.message.Message.get_param() and friends.
787 Specifically in some cases where non-encoded continuations were used,
788 get_param() used to return a 3-tuple of (None, None, string) whereas now it
789 will just return the string (since non-encoded continuations don't have
790 charset and language parts).
791
792 Also, whereas % values were decoded in all parameter continuations, they are
793 now only decoded in encoded parameter parts.
794
Ronald Oussoren3075e162006-07-25 20:28:55 +0000795- Bug #1517990: IDLE keybindings on MacOS X now work correctly
796
797- Bug #1517996: IDLE now longer shows the default Tk menu when a
798 path browser, class browser or debugger is the frontmost window on MacOS X
799
Barry Warsaw00decd72006-07-27 23:43:15 +0000800- Patch #1520294: Support for getset and member descriptors in types.py,
801 inspect.py, and pydoc.py. Specifically, this allows for querying the type
802 of an object against these built-in types and more importantly, for getting
803 their docstrings printed in the interactive interpreter's help() function.
804
Ronald Oussoren3075e162006-07-25 20:28:55 +0000805

807-----------------
808
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000809- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
810 a socket operation on a socket with a timeout, the exception will be
811 caught correctly. Previously, the exception was not caught.
812
Thomas Heller1393d6a2006-07-28 21:43:20 +0000813- Patch #1529514: The _ctypes extension is now compiled on more
814 openbsd target platforms.
815
Tim Peters9cab5932006-07-28 00:30:00 +0000816- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
817 a memory leak, affecting pickles and deep copies.
818
Tim Petersbc24eee2006-07-27 01:14:53 +0000819- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000820 Paul Eggert.
821
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000822- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
823
Thomas Hellerce049a02006-07-14 17:51:14 +0000824- Patch #1521817: Index range checking on ctypes arrays containing
825 exactly one element enabled again. This allows iterating over these
826 arrays, without the need to check the array size before.
827
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000828- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000829 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000830 /dev/null in certain cases; this is now fixed.
831
Thomas Heller47d7a062006-07-12 08:43:47 +0000832- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
833 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000834
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000835- Because of a misspelled preprocessor symbol, ctypes was always
836 compiled without thread support; this is now fixed.
837
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000838- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
839 methods now allow their database parameter to be None as the
840 sleepycat API allows.
841
Matt Flemingec926502006-07-28 11:27:27 +0000842- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
843 bluetooth API compared with Linux and FreeBSD.
844
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000845Tests
846-----
847
848- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
849 how long the test file should take to play. Now accepts taking 2.93 secs
850 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
851
Georg Brandl4793aa32006-07-28 18:31:39 +0000852- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
853 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
854 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +0000855
Martin v. Löwis0907f4d2006-07-30 14:09:47 +0000856Build

859- Bug #1439538: Drop usage of test -e in configure as it is not portable.
860
Ronald Oussoren26cad082006-08-01 21:00:57 +0000861Mac
862---
863
864- PythonLauncher now works correctly when the path to the script contains
865 characters that are treated specially by the shell (such as quotes).
866
867- Bug #1527397: PythonLauncher now launches scripts with the working directory
868 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000869 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000870 expect.

880
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000881- Bug #1441486: The literal representation of -(sys.maxint - 1)
882 again evaluates to a int object, not a long.
883
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000884- Bug #1501934: The scope of global variables that are locally assigned
885 using augmented assignment is now correctly determined.
886
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000887- Bug #927248: Recursive method-wrapper objects can now safely
888 be released.
889
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000890- Bug #1417699: Reject locale-specific decimal point in float()
891 and atof().
892
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000893- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
894 omit a default "error" argument for NULL pointer. This allows
895 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000896
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000897- Bug #1519018: 'as' is now validated properly in import statements.
898
Neal Norwitz28746ab2006-07-09 22:14:42 +0000899- On 64 bit systems, int literals that use less than 64 bits are
900 now ints rather than longs.
901
Neal Norwitzed657552006-07-10 00:04:44 +0000902- Bug #1512814, Fix incorrect lineno's when code at module scope
903 started after line 256.
904
Tim Peters32a83612006-07-10 21:08:24 +0000905- New function ``sys._current_frames()`` returns a dict mapping thread
906 id to topmost thread stack frame. This is for expert use, and is
907 especially useful for debugging application deadlocks. The functionality
908 was previously available in Fazal Majid's ``threadframe`` extension
909 module, but it wasn't possible to do this in a wholly threadsafe way from
910 an extension.

930 be treated as the value they contain, instead.
931
Martin v. Löwisede77f52006-07-03 13:01:35 +0000932- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

957
Brett Cannon53ab5b72006-06-22 16:49:14 +0000958- Bug #1510580: The 'warnings' module improperly required that a Warning
959 category be either a types.ClassType and a subclass of Warning. The proper
960 check is just that it is a subclass with Warning as the documentation states.
961
Georg Brandlad29e632006-06-21 17:45:17 +0000962- The compiler module now correctly compiles the new try-except-finally

Tim Peters112aad32006-07-19 00:03:19 +0000977- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
978 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
979 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000980
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000981- Assigning None to pointer type fields in ctypes structures possible
982 overwrote the wrong fields, this is fixed now.
983
984- Fixed a segfault in _ctypes when ctypes.wintypes were imported
985 on non-Windows platforms.
986
987- Bug #1518190: The ctypes.c_void_p constructor now accepts any
988 integer or long, without range checking.
989
990- Patch #1517790: It is now possible to use custom objects in the ctypes
991 foreign function argtypes sequence as long as they provide a from_param
992 method, no longer is it required that the object is a ctypes type.
993
994- The '_ctypes' extension module now works when Python is configured
995 with the --without-threads option.

1012
Tim Peters32a83612006-07-10 21:08:24 +00001013- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001014 Previously, the slight difference could cause compilation errors of the
1015 'zlib' module on systems with more than one version of zlib.
1016
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001017- The MSI compileall step was fixed to also support a TARGETDIR

1049-----------------
1050
Georg Brandla56b9152006-06-19 06:35:54 +00001051- Patch #1507676: Error messages returned by invalid abstract object operations
1052 (such as iterating over an integer) have been improved and now include the
1053 type of the offending object to help with debugging.
1054
Brett Cannonea3912b2006-06-13 21:46:41 +00001055- Bug #992017: A classic class that defined a __coerce__() method that returned
1056 its arguments swapped would infinitely recurse and segfault the interpreter.
1057
Neal Norwitz909eb122006-06-12 02:13:21 +00001058- Fix the socket tests so they can be run concurrently.
1059
Neal Norwitzb9845e72006-06-12 02:11:18 +00001060- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001061 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001062
Brett Cannon22565aa2006-06-09 22:31:23 +00001063- Bug #532646: object.__call__() will continue looking for the __call__
1064 attribute on objects until one without one is found. This leads to recursion
1065 when you take a class and set its __call__ attribute to an instance of the
1066 class. Originally fixed for classic classes, but this fix is for new-style.
1067 Removes the infinite_rec_3 crasher.
1068
Georg Brandl24250812006-06-09 18:45:48 +00001069- The string and unicode methods startswith() and endswith() now accept
1070 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1071
Brett Cannonde3b0522006-06-08 17:00:45 +00001072- Buffer objects, at the C level, never used the char buffer
1073 implementation even when the char buffer for the wrapped object was
1074 explicitly requested (originally returned the read or write buffer).
1075 Now a TypeError is raised if the char buffer is not present but is
1076 requested.
1077
Georg Brandlddbaa662006-06-04 21:56:52 +00001078- Patch #1346214: Statements like "if 0: suite" are now again optimized
1079 away like they were in Python 2.4.
1080
Georg Brandlb7c8f542006-05-27 12:30:25 +00001081- Builtin exceptions are now full-blown new-style classes instead of
1082 instances pretending to be classes, which speeds up exception handling
1083 by about 80% in comparison to 2.5a2.
1084
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001085- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1086 Unicode 4.1.
1087
Georg Brandlf4ef1162006-05-26 18:03:31 +00001088- Patch #921466: sys.path_importer_cache is now used to cache valid and
1089 invalid file paths for the built-in import machinery which leads to
1090 fewer open calls on startup.
1091
Tim Peters696cf432006-05-24 21:10:40 +00001092- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1093 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1094 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1095 the number of input digits (it was and remains linear-time for bases
1096 2, 4, 8, 16 and 32).
1097
Tim Petersb713ec22006-05-23 18:45:30 +00001098- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1099 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1100 an integer close to ``sys.maxint``. This was repaired by patch
1101 #1335972, which also gives a nice speedup.
1102
Richard Jonescebbefc2006-05-23 18:28:17 +00001103- Patch #1337051: reduced size of frame objects.
1104
1105- PyErr_NewException now accepts a tuple of base classes as its
1106 "base" parameter.
1107
Richard Jones7c88dcc2006-05-23 10:37:38 +00001108- Patch #876206: function call speedup by retaining allocated frame
1109 objects.
1110
Georg Brandl7b90e162006-05-18 07:01:27 +00001111- Bug #1462152: file() now checks more thoroughly for invalid mode
1112 strings and removes a possible "U" before passing the mode to the
1113 C library function.
1114
Neal Norwitz1004a532006-05-15 07:17:23 +00001115- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1116
Neal Norwitz373f0a72006-05-15 07:04:36 +00001117- Bug #1487966: Fix SystemError with conditional expression in assignment
1118
Martin v. Löwis879768d2006-05-11 13:28:43 +00001119- WindowsError now has two error code attributes: errno, which carries
1120 the error values from errno.h, and winerror, which carries the error
1121 values from winerror.h. Previous versions put the winerror.h values
1122 (from GetLastError()) into the errno attribute.
1123
Martin v. Löwis77736712006-05-04 05:51:03 +00001124- Patch #1475845: Raise IndentationError for unexpected indent.
1125
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001126- Patch #1479181: split open() and file() from being aliases for each other.
1127
Tim Peters44bd9862006-06-01 13:49:23 +00001128- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1129 methods were always silently ignored by dictionaries when comparing keys.
1130 They are now passed through (except when using the C API function
1131 ``PyDict_GetItem()``, whose semantics did not change).
1132
1133- Bug #1456209: In some obscure cases it was possible for a class with a
1134 custom ``__eq__()`` method to confuse dict internals when class instances
1135 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1136 No, you don't have any code that did this ;-)

1144
Brett Cannon6ee7d012006-06-08 16:23:04 +00001145- Change binascii.hexlify to accept a read-only buffer instead of only a char
1146 buffer and actually follow its documentation.
1147
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001148- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1149
Nick Coghlanc649ec52006-05-29 12:43:05 +00001150- Patch #1478788 (modified version): The functional extension module has
1151 been renamed to _functools and a functools Python wrapper module added.
1152 This provides a home for additional function related utilities that are
1153 not specifically about functional programming. See PEP 309.
1154
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001155- Patch #1493701: performance enhancements for struct module.

1160 copy() method.
1161
Andrew MacIntyre92913322006-06-13 15:04:24 +00001162- Patch #1454481: thread stack size is now tunable at runtime for thread
1163 enabled builds on Windows and systems with Posix threads support.
1164
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001165- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1166 (up to the system limit of 32K characters).
1167
1168- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1169 As a result, these functions now raise WindowsError instead of OSError.
1170
Tim Peters7a822da2006-05-25 21:50:17 +00001171- ``time.clock()`` on Win64 should use the high-performance Windows
1172 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1173 Windows platforms).
1174
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001175- Calling Tk_Init twice is refused if the first call failed as that
1176 may deadlock.
1177
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001178- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1179 accept it without potentially using an uninitialized pointer.
1180
1181- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1182 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1183 patch numbers 1494885 and 1494902]

1192 results. It could previously incorrectly return 0 in some cases.
1193 Fixes SF bug 1493322 (pybsddb bug 1184012).
1194
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001195- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1196 aborts the db transaction safely when a modifier callback fails.
1197 Fixes SF python patch/bug #1408584.

Gregory P. Smith506f7b52006-06-15 08:52:32 +00001199- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001200 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001201 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1202 database calls that would previously deadlock. [SF python bug #775414]

1226 mime.types file for determining MIME types.
1227
Georg Brandl2605ca82006-06-14 06:08:31 +00001228- Bug #1339007: Shelf objects now don't raise an exception in their
1229 __del__ method when initialization failed.
1230
Martin v. Löwisd8251432006-06-14 05:21:04 +00001231- Patch #1455898: The MBCS codec now supports the incremental mode for
1232 double-byte encodings.
1233
Tim Peters43898b42006-06-14 04:09:25 +00001234- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1235 guarantee that adjacent triples in the return list always describe
1236 non-adjacent blocks. Previously, a pair of matching blocks could end
1237 up being described by multiple adjacent triples that formed a partition
1238 of the matching pair.
1239
Greg Ward0e0c9f42006-06-11 16:24:11 +00001240- Bug #1498146: fix optparse to handle Unicode strings in option help,
1241 description, and epilog.
1242
Greg Wardd1c797e2006-06-11 14:42:41 +00001243- Bug #1366250: minor optparse documentation error.

1246 clarify docs.
1247
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001248- The wsgiref package has been added to the standard library.
1249
Nick Coghlan676725d2006-06-08 13:54:49 +00001250- The functions update_wrapper() and wraps() have been added to the functools
1251 module. These make it easier to copy relevant metadata from the original
1252 function when writing wrapper functions.
1253
Tim Petersd6a9eef2006-06-05 01:48:21 +00001254- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1255 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001256
Martin v. Löwis3f767792006-06-04 19:36:28 +00001257- Patch #1359618: Speed up charmap encoder by using a trie structure
1258 for lookup.
1259
Tim Petersd609b1a2006-06-02 23:22:51 +00001260- The functions in the ``pprint`` module now sort dictionaries by key
1261 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1262 if and only if its display required more than one line, although that
1263 wasn't documented. The new behavior increases predictability; e.g.,
1264 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1265
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001266- Patch #1497027: try HTTP digest auth before basic auth in urllib2

Georg Brandlb89316f2006-05-17 15:51:16 +00001276- Patch #1180296: Two new functions were added to the locale module:
1277 format_string() to get the effect of "format % items" but locale-aware,
1278 and currency() to format a monetary number with currency sign.

1281 and several features added, such as speed and geometry control.
1282
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001283- Patch #1488881: add support for external file objects in bz2 compressed
1284 tarfiles.
1285
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001286- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1287 stdout arguments, making it possible to redirect input and output
1288 for remote debugging.
1289
1290- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1291 a couple of issues, notably handling of long file names using the
1292 GNU LONGNAME extension.
1293
1294- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1295 new flag when ``name`` is already the name of an option flag.
1296
1297- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1298 package.
1299
1300- Patch #1472854: make the rlcompleter.Completer class usable on non-
1301 UNIX platforms.

1338
1339*Release date: 27-APR-2006*
1340
1341Core and builtins
1342-----------------
1343
Thomas Heller1b046642006-04-18 18:51:06 +00001344- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1345 by converting these apis from macros into exported functions again:
1346
1347 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1348 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1349 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1350 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1351 PyRun_String Py_CompileString
1352
Martin v. Löwis45294a92006-04-18 06:24:08 +00001353- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1354
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001355- All uses of PyStructSequence_InitType have been changed to initialize
1356 the type objects only once, even if the interpreter is initialized
1357 multiple times.
1358
Neal Norwitz61546162006-04-14 05:20:28 +00001359- Bug #1454485, array.array('u') could crash the interpreter. This was
1360 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1361 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1362
1363- Py_UNICODE is unsigned. It was always documented as unsigned, but
1364 due to a bug had a signed value in previous versions.
1365
Tim Peters3a5e8b12006-04-11 01:44:07 +00001366- Patch #837242: ``id()`` of any Python object always gives a positive
1367 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1368 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001369 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001370 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001371
Tim Peters3a5e8b12006-04-11 01:44:07 +00001372 def __hash__(self):
1373 return id(self) # WRONG
1374
1375 because a hash result must be a (short) Python int but it was always
1376 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001377 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001378 was always usable as a hash value before this patch. That's no longer
1379 necessarily so.
1380
1381- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001382 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001383 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001384 #1454844)
1385
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001386- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1387 involving generators that have paused outside of any ``try`` or ``with``
1388 blocks. (In 2.5a1, a paused generator that was part of a reference
1389 cycle could not be garbage collected, regardless of whether it was
1390 paused in a ``try`` or ``with`` block.)

1410 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001411
Armin Rigoa9017c32006-04-19 11:50:27 +00001412- Patch #1062014: AF_UNIX sockets under Linux have a special

1420 abusing errno.
1421
Tim Peters711bf302006-04-25 03:31:36 +00001422- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1423 a doctest to be skipped (the code is not run, and the expected output
1424 or exception is ignored).
1425
Nick Coghlanda2268f2006-04-24 04:37:15 +00001426- Fixed contextlib.nested to cope with exceptions being raised and
1427 caught inside exit handlers.
1428
Greg Wardab05edc2006-04-23 03:47:58 +00001429- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1430 hex, octal, or binary; add ``append_const`` action; keep going if
1431 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1432 added ``epilog`` for better help generation).
1433
Tim Peters21fbd572006-04-21 21:18:10 +00001434- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1435 called from a thread spawned as a side effect of importing a module.
1436
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001437- The pydoc module now supports documenting packages contained in
1438 .zip or .egg files.
1439
1440- The pkgutil module now has several new utility functions, such
1441 as ``walk_packages()`` to support working with packages that are either
1442 in the filesystem or zip files.
1443
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001444- The mailbox module can now modify and delete messages from
1445 mailboxes, in addition to simply reading them. Thanks to Gregory
1446 K. Johnson for writing the code, and to the 2005 Google Summer of
1447 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001448
Tim Petersc7605f22006-04-17 21:12:33 +00001449- The ``__del__`` method of class ``local`` in module ``_threading_local``
1450 returned before accomplishing any of its intended cleanup.
1451
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001452- Patch #790710: Add breakpoint command lists in pdb.

Nick Coghlan27ec1a72006-04-24 04:32:47 +00001504- test_cmd_line now checks operation of the -m and -c command switches
1505
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001506- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1507 it separately and by hand. It also wasn't cleaning up its changes to
1508 the current Decimal context.
1509
Thomas Woutersabd08882006-04-26 15:53:30 +00001510- regrtest.py now has a -M option to run tests that test the new limits of
1511 containers, on 64-bit architectures. Running these tests is only sensible
1512 on 64-bit machines with more than two gigabytes of memory. The argument
1513 passed is the maximum amount of memory for the tests to use.

1522-------------
1523
Tim Petersb06d28c2006-05-12 01:57:59 +00001524- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1525
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001526- PEP 343: Added Context Types section to the library reference
1527 and attempted to bring other PEP 343 related documentation into
1528 line with the implementation and/or python-dev discussions.
1529
Tim Peters8dc73d22006-04-24 02:03:16 +00001530- Bug #1337990: clarified that ``doctest`` does not support examples
1531 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001534What's New in Python 2.5 alpha 1?
1535=================================
1536
Anthony Baxterebed3f62006-04-03 15:03:44 +00001537*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001538
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001539Core and builtins
1540-----------------
1541
Nick Coghlan43832302006-04-23 17:04:07 +00001542- PEP 338: -m command line switch now delegates to runpy.run_module
1543 allowing it to support modules in packages and zipfiles
1544
Martin v. Löwisc661b882006-04-20 04:54:23 +00001545- On Windows, .DLL is not an accepted file name extension for
1546 extension modules anymore; extensions are only found if they
1547 end in .PYD.
1548
Martin v. Löwisea62d252006-04-03 10:56:49 +00001549- Bug #1421664: sys.stderr.encoding is now set to the same value as
1550 sys.stdout.encoding.
1551
Neal Norwitz92e212f2006-04-03 04:48:37 +00001552- __import__ accepts keyword arguments.
1553
Georg Brandlccadf842006-03-31 18:54:53 +00001554- Patch #1460496: round() now accepts keyword arguments.
1555
Anthony Baxter262c00a2006-03-30 10:53:17 +00001556- Fixed bug #1459029 - unicode reprs were double-escaped.
1557
Hye-Shik Changd478f342006-03-23 12:32:36 +00001558- Patch #1396919: The system scope threads are reenabled on FreeBSD
1559 5.4 and later versions.
1560
Neal Norwitze98ccf62006-03-23 05:39:47 +00001561- Bug #1115379: Compiling a Unicode string with an encoding declaration
1562 now gives a SyntaxError.
1563
Georg Brandlabd1ff82006-03-18 07:59:59 +00001564- Previously, Python code had no easy way to access the contents of a
1565 cell object. Now, a ``cell_contents`` attribute has been added
1566 (closes patch #1170323).
1567
Tim Peterscf79aac2006-03-16 01:14:46 +00001568- Patch #1123430: Python's small-object allocator now returns an arena to
1569 the system ``free()`` when all memory within an arena becomes unused
1570 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1571 freed. Some applications will see a drop in virtual memory size now,
1572 especially long-running applications that, from time to time, temporarily
1573 use a large number of small objects. Note that when Python returns an
1574 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001575 platform C library will in turn return that memory to the operating system.
1576 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001577 appears to be effective at least on Microsoft C and gcc-based systems.
1578 Thanks to Evan Jones for hard work and patience.
1579
Georg Brandl533ff6f2006-03-08 18:09:27 +00001580- Patch #1434038: property() now uses the getter's docstring if there is
1581 no "doc" argument given. This makes it possible to legitimately use
1582 property() as a decorator to produce a read-only property.
1583
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001584- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1585 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1586 of requiring an int or long in slicing and a few other contexts, enabling
1587 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1588
Neal Norwitz995acdf2006-03-07 05:01:00 +00001589- Fixed various bugs reported by Coverity's Prevent tool.
1590
Brett Cannonbf364092006-03-01 04:25:17 +00001591- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1592 new exception base class, BaseException, which has a new message attribute.
1593 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1594 Raising a string exception now raises a DeprecationWarning.
1595
Thomas Woutersfb609f42006-02-28 16:37:25 +00001596- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1597 explicitly relative, using 'from .module import name' to mean 'from the same
1598 package as this module is in. Imports without dots still default to the
1599 old relative-then-absolute, unless 'from __future__ import
1600 absolute_import' is used.
1601
Brett Cannona7446e32006-02-27 23:39:10 +00001602- Properly check if 'warnings' raises an exception (usually when a filter set
1603 to "error" is triggered) when raising a warning for raising string
1604 exceptions.
1605
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001606- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001607 The name was removed from Include/code.h.
1608
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001609- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001610
Guido van Rossum1968ad32006-02-25 22:38:04 +00001611- Patch 1433928:
1612 - The copy module now "copies" function objects (as atomic objects).
1613 - dict.__getitem__ now looks for a __missing__ hook before raising
1614 KeyError.
1615
Tim Peters84ef21c2006-02-28 20:39:06 +00001616- PEP 343: with statement implemented. Needs ``from __future__ import
1617 with_statement``. Use of 'with' as a variable will generate a warning.
1618 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001619 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001620 The following objects have __context__ methods:
1621 - The built-in file type.
1622 - The thread.LockType type.
1623 - The following types defined by the threading module:
1624 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1625 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001626
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001627- Fix the encodings package codec search function to only search
1628 inside its own package. Fixes problem reported in patch #1433198.
1629
1630 Note: Codec packages should implement and register their own
1631 codec search function. PEP 100 has the details.
1632
Tim Peters9ea89d22006-06-04 03:26:02 +00001633- PEP 353: Using ``Py_ssize_t`` as the index type.
1634
1635- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1636 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1637 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1638 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1639 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001640
Neal Norwitzfc76d632006-01-10 06:03:13 +00001641- Patch #1400181, fix unicode string formatting to not use the locale.
1642 This is how string objects work. u'%f' could use , instead of .
1643 for the decimal point. Now both strings and unicode always use periods.
1644
Neal Norwitz671b9e32006-01-09 07:07:12 +00001645- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1646 configure would break checking curses.h.
1647
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001648- Bug #959576: The pwd module is now builtin. This allows Python to be
1649 built on UNIX platforms without $HOME set.
1650
Neal Norwitzc10978f2005-12-19 06:07:16 +00001651- Bug #1072182, fix some potential problems if characters are signed.
1652
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001653- Bug #889500, fix line number on SyntaxWarning for global declarations.
1654
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001655- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1656
Neal Norwitze7214a12005-12-18 05:03:17 +00001657- Support for converting hex strings to floats no longer works.
1658 This was not portable. float('0x3') now raises a ValueError.
1659
Barry Warsaw2a38a862005-12-18 01:27:35 +00001660- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001661 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001662 is now displayed in interactive prompt banner.
1663
Georg Brandlfa166682005-12-17 21:45:17 +00001664- Implementation of PEP 341 - Unification of try/except and try/finally.
1665 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001666 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001667
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001668- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1669 now encodes backslash correctly.
1670
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001671- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1672
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001673- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001674 and long longs.
1675
Neal Norwitz67715f02005-11-09 06:59:35 +00001676- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001677 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001678 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001679
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001680- Replaced most Unicode charmap codecs with new ones using the
1681 new Unicode translate string feature in the builtin charmap
1682 codec; the codecs were created from the mapping tables available
1683 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1684 encodings now include a mapping for the Apple logo)
1685
Tim Peterse3547fd2005-12-16 23:13:57 +00001686- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001687
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001688- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001689
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001690- A new AST parser implementation was completed. The abstract
1691 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001692 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001693
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001694- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001695 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1696
Neal Norwitz708e51a2005-10-03 04:48:15 +00001697- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1698
Neal Norwitz11bd1192005-10-03 00:54:56 +00001699- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1700 Provide a warning when a directory is passed on the command line.
1701
Neal Norwitz40d37812005-10-02 01:48:49 +00001702- Fix segfault with invalid coding.
1703
1704- SF bug #772896: unknown encoding results in MemoryError.
1705
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001706- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001707 supported a __len__() method which evaluated to False when the iterator
1708 was empty.
1709
Guido van Rossum630db602005-09-20 18:49:54 +00001710- On 64-bit platforms, when __len__() returns a value that cannot be
1711 represented as a C int, raise OverflowError.
1712
Skip Montanarof8948ca2005-09-19 03:54:46 +00001713- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001714 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001715
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001716- SF bug #893549: parsing keyword arguments was broken with a few format
1717 codes.
1718
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001719- Changes donated by Elemental Security to make it work on AIX 5.3
1720 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1721 bug #105470: test_pwd fails on 64bit system (Opteron).
1722
Guido van Rossum539c6622005-09-14 17:49:54 +00001723- Changes donated by Elemental Security to make it work on HP-UX 11 on
1724 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1725
Georg Brandl4550b8d2005-08-26 06:43:52 +00001726- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001727 (fixes bug #1119418).
1728
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001729- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1730
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001731- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1732 exceptions that cause a function to exit.
1733
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001734- The implementation of set() and frozenset() was revised to use its
1735 own internal data structure. Memory consumption is reduced by 1/3
1736 and there are modest speed-ups as well. The API is unchanged.
1737
Tim Petersde7990b2005-07-17 23:45:23 +00001738- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1739
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001740- SF bug #1229429: PyObject_CallMethod failed to decrement some
1741 reference counts in some error exit cases.
1742
Tim Petersecc6e6a2005-07-10 22:30:55 +00001743- SF bug #1185883: Python's small-object memory allocator took over
1744 a block managed by the platform C library whenever a realloc specified
1745 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001746 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001747 portable way to copy data from the C-managed block into Python's
1748 small-object space without risking a memory fault. Python's small-object
1749 realloc now leaves such blocks under the control of the platform C
1750 realloc.
1751
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001752- SF bug #1232517: An overflow error was not detected properly when
1753 attempting to convert a large float to an int in os.utime().
1754
Raymond Hettinger3296e692005-06-29 23:29:56 +00001755- SF bug #1224347: hex longs now print with lowercase letters just
1756 like their int counterparts.
1757
Michael W. Hudson188d4362005-06-20 16:52:57 +00001758- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1759 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1760 interpreter states; back out that fix and do a better job (see
1761 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1762 for a longer write-up of the problem).
1763
Michael W. Hudsondf888462005-06-03 14:41:55 +00001764- SF patch #1180995: marshal now uses a binary format by default when
1765 serializing floats.
1766
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001767- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1768 the routines that promise to produce IEEE 754 binary representations
1769 of floats now simply copy bytes around.
1770
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001771- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1772 278.

Brett Cannonc3647ac2005-04-26 03:45:26 +00001774- patch #1109424: int, long, float, complex, and unicode now check for the
1775 proper magic slot for type conversions when subclassed. Previously the
1776 magic slot was ignored during conversion. Semantics now match the way
1777 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001778 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001779 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001780 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001781
Barry Warsawc8d907c2005-04-19 23:43:40 +00001782- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1783 NULL, now raise an AttributeError when attempting to set or delete the
1784 attribute. Previously a TypeError was raised, but this was inconsistent
1785 with the equivalent pure-Python implementation.
1786
Michael W. Hudson774479c2005-04-18 08:46:17 +00001787- It is now safe to call PyGILState_Release() before
1788 PyEval_InitThreads() (note that if there is reason to believe there
1789 are multiple threads around you still must call PyEval_InitThreads()
1790 before using the Python API; this fix is for extension modules that
1791 have no way of knowing if Python is multi-threaded yet).
1792
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001793- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1794 disabled caused a crash.
1795
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001796- Bug #1165306: instancemethod_new allowed the creation of a method
1797 with im_class == im_self == NULL, which caused a crash when called.
1798
Tim Petersecc6e6a2005-07-10 22:30:55 +00001799- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001800 fixes the crash seen in bug #1165761
1801
Raymond Hettinger96229b12005-03-11 06:49:40 +00001802- Added two new builtins, any() and all().
1803
Brett Cannon409d8f22005-03-05 06:47:57 +00001804- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001805 (e.g., ``class C(): pass`` is no longer a syntax error).
1806 Patch #1176012 added support to the 'parser' module and 'compiler' package
1807 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001808

1810
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001811- Bug #1155938: new style classes did not check that __init__() was
1812 returning None.
1813
Tim Petersecc6e6a2005-07-10 22:30:55 +00001814- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001815 ('\') with a specific error message.
1816
Martin v. Löwisff232d72005-03-03 09:24:38 +00001817- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1818
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001819- Bug #1124295: the __name__ attribute of file objects was
1820 inadvertently made inaccessible in restricted mode.
1821
Tim Petersecc6e6a2005-07-10 22:30:55 +00001822- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001823 an ferror() call.
1824
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001825- min() and max() now support key= arguments with the same meaning as in
1826 list.sort().
1827
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001828- The peephole optimizer now performs simple constant folding in expressions:
1829 (2+3) --> (5).
1830
Raymond Hettingera422c342005-01-11 03:03:27 +00001831- set and frozenset objects can now be marshalled. SF #1098985.
1832
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001833- Bug #1077106: Poor argument checking could cause memory corruption
1834 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001835
Jeremy Hyltonab630502005-02-04 18:44:06 +00001836- The parser did not complain about future statements in illegal
1837 positions. It once again reports a syntax error if a future
1838 statement occurs after anything other than a doc string.
1839
Neil Schemenauercf52c072005-08-12 17:34:58 +00001840- Change the %s format specifier for str objects so that it returns a
1841 unicode instance if the argument is not an instance of basestring and
1842 calling __str__ on the argument returns a unicode instance.
1843
Tim Petersf4e69282006-02-27 17:15:31 +00001844- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1845 current thread state when the auto-GIL-state machinery knows about
1846 it (since the thread state is being deleted, continuing to remember it
1847 can't help, but can hurt if another thread happens to get created with
1848 the same thread id).

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002040- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2041 been renamed to have only a single underscore prefix. This was done to
2042 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002043
Nick Coghlan43832302006-04-23 17:04:07 +00002044- PEP 338: new module runpy defines a run_module function to support
2045 executing modules which provide access to source code or a code object
2046 via the PEP 302 import mechanisms.
2047
Anthony Baxter93f5b932006-04-03 08:05:07 +00002048- The email module's parsedate_tz function now sets the daylight savings
2049 flag to -1 (unknown) since it can't tell from the date whether it should
2050 be set.
2051

2053 now sport attributes that provide access to the parts of the result.
2054

2056 in attribute values.
2057
Anthony Baxterc51ee692006-04-01 00:57:31 +00002058- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002059 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002060 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002061 module will not be built.
2062
Tim Petersc17976e2006-04-01 00:26:53 +00002063- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2064 aren't officially supported here, and trying to use them will probably
2065 raise an exception some day. But dicts have been allowed, and "mostly
2066 worked", so support for them won't go away without warning.
2067
Georg Brandl338ef7d2006-03-31 18:42:16 +00002068- Bug #1445068: getpass.getpass() can now be given an explicit stream
2069 argument to specify where to write the prompt.
2070
Georg Brandl22ec80b2006-03-31 18:25:44 +00002071- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2077 key to be used for signing the uploaded code.
2078
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002079- Queue.Queue objects now support .task_done() and .join() methods
2080 to make it easier to monitor when daemon threads have completed
2081 processing all enqueued tasks. Patch #1455676.
2082
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002083- popen2.Popen objects now preserve the command in a .cmd attribute.
2084
Thomas Hellerc61c0492006-03-22 10:09:27 +00002085- Added the ctypes ffi package.
2086
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002087- email 4.0 package now integrated. This is largely the same as the email 3.0
2088 package that was included in Python 2.3, except that PEP 8 module names are
2089 now used (e.g. mail.message instead of email.Message). The MIME classes
2090 have been moved to a subpackage (e.g. email.mime.text instead of
2091 email.MIMEText). The old names are still supported for now. Several
2092 deprecated Message methods have been removed and lots of bugs have been
2093 fixed. More details can be found in the email package documentation.
2094
Walter Dörwald40108c92006-03-27 08:15:44 +00002095- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2096 (a subclass of tuple) that provides incremental decoders and encoders
2097 (a way to use stateful codecs without the stream API). Python functions
2098 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2099 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2100 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002101
Walter Dörwald067db482006-03-15 22:17:27 +00002102- Patch #1359365: Calling next() on a closed StringIO.String object raises
2103 a ValueError instead of a StopIteration now (like file and cString.String do).
2104 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2105 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002106
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002107- A regrtest option -w was added to re-run failed tests in verbose mode.

2110 interpreter to exit.
2111
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002112- The function get_count() has been added to the gc module, and gc.collect()

2180 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2181 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2182 Ronald L. Rivest offered this advice for Python:
2183
2184 "The consensus of researchers in this area (at least as
2185 expressed at the NIST Hash Function Workshop 10/31/05),
2186 is that SHA-256 is a good choice for the time being, but
2187 that research should continue, and other alternatives may
2188 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002189
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002190- Added a subset of Fredrik Lundh's ElementTree package. Available

2301 files to PyPI.
2302
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002303- distutils.commands.register now encodes the data as UTF-8 before posting
2304 them to PyPI.
2305
Raymond Hettinger267b8682005-03-27 10:47:39 +00002306- decimal operator and comparison methods now return NotImplemented
2307 instead of raising a TypeError when interacting with other types. This
2308 allows other classes to implement __radd__ style methods and have them
2309 work as expected.
2310
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002311- Bug #1163325: Decimal infinities failed to hash. Attempting to
2312 hash a NaN raised an InvalidOperation instead of a TypeError.
2313
Tim Petersecc6e6a2005-07-10 22:30:55 +00002314- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002315 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2316

Martin v. Löwisc72dd382005-03-04 13:50:17 +00002319- Patch #1075887: Don't require MSVC in distutils if there is nothing
2320 to build.
2321
Martin v. Löwis637431b2005-03-03 23:12:42 +00002322- Patch #1103407: Properly deal with tarfile iterators when untarring
2323 symbolic links on Windows.
2324
Tim Petersecc6e6a2005-07-10 22:30:55 +00002325- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +00002326 profile.py if available.
2327
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00002328- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
2329
Martin v. Löwisc5574e82005-03-03 10:57:37 +00002330- Patch #1117454: Remove code to special-case cookies without values
2331 in LWPCookieJar.
2332
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00002333- Patch #1117339: Add cookielib special name tests.

2336
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00002337- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
2338
Martin v. Löwisdf241532005-03-03 08:17:42 +00002339- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
2340
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00002341- Patch #1104111: Alter setup.py --help and --help-commands.
2342
Martin v. Löwis4afe1542005-03-01 08:09:28 +00002343- Patch #1121234: Properly cleanup _exit and tkerror commands.
2344
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00002345- Patch #1049151: xdrlib now unpacks booleans as True or False.
2346
Raymond Hettingerbab41432005-02-05 01:31:19 +00002347- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2348
Guido van Rossumd0641422005-02-03 15:01:24 +00002349- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2350 disables recursive traversal through instance attributes, which can
2351 be exploited in various ways.
2352
Tim Peterse3547fd2005-12-16 23:13:57 +00002353- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002354 flags on the HTTP listening socket.
2355
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002356- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2357 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2358
Fred Drakefbdeaad2006-07-29 16:56:15 +00002359- Patches #893642, #1039083: add allow_none, encoding arguments to
2360 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002361
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002362- Bug #1110478: Revert os.environ.update to do putenv again.
2363
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002364- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2365
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002366- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2367
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002368- Enhancements to the csv module:
2369
2370 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002371 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002372 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002373 + Dialect parameter parsing has been re-implemented to improve error
2374 reporting.
2375 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2376 dictates.
2377 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002378 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002379 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002380 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2381 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002382 + reader now allows \r characters to be quoted (previously it only allowed
2383 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002384 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002385 + Dialect classes passed to the module are no longer instantiated by
2386 the module before being parsed (the former validation scheme required
2387 this, but the mechanism was unreliable).
2388 + The dialect registry now contains instances of the internal
2389 C-coded dialect type, rather than references to python objects.
2390 + the internal c-coded dialect type is now immutable.
2391 + register_dialect now accepts the same keyword dialect specifications
2392 as the reader and writer, allowing the user to register dialects
2393 without first creating a dialect class.
2394 + a configurable limit to the size of parsed fields has been added -
2395 previously, an unmatched quote character could result in the entire
2396 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002397 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002398 the parser field size limit (returning the former limit). The initial
2399 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002400 + A line_num attribute has been added to the reader object, which tracks
2401 the number of lines read from the source iterator. This is not
2402 the same as the number of records returned, as records can span
2403 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002404 + reader and writer objects were not being registered with the cyclic-GC.
2405 This has been fixed.
2406
Brett Cannone6539c42005-01-08 02:43:53 +00002407- _DummyThread objects in the threading module now delete self.__block that is
2408 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2409 lock primitives tend to be limited in number and thus should not be wasted on
2410 a _DummyThread object. Fixes bug #1089632.
2411
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002412- The imghdr module now detects Exif files.
2413
Raymond Hettinger6065d322004-12-20 23:51:53 +00002414- StringIO.truncate() now correctly adjusts the size attribute.
2415 (Bug #951915).
2416
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002417- locale.py now uses an updated locale alias table (built using
2418 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2419 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002420 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002421
Raymond Hettinger3557f422004-12-07 12:02:02 +00002422- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2423
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002424- the pickle module no longer accepts the deprecated None option in the
2425 args tuple returned by __reduce__().
2426
Brett Cannon84667c02004-12-07 03:25:18 +00002427- optparse now optionally imports gettext. This allows its use in setup.py.
2428
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002429- the pickle module no longer uses the deprecated bin parameter.
2430
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002431- the shelve module no longer uses the deprecated binary parameter.
2432
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002433- the pstats module no longer uses the deprecated ignore() method.
2434
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002435- the filecmp module no longer uses the deprecated use_statcache argument.
2436
Raymond Hettinger664347b2004-12-04 21:21:53 +00002437- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2438 extended or overridden by subclasses. Formerly, the subclassed method would
2439 be ignored by the rest of the module. (Bug #1078905).
2440
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002441- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002442 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002443
Walter Dörwald36733692004-12-22 12:50:50 +00002444- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2445 once when a size argument is given. This prevents a buffer overflow in the
2446 tokenizer with very long source lines.
2447
Barry Warsaw538561e2006-01-01 21:48:54 +00002448- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2449 immediately after creating the object, without any intervening
2450 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002451
Skip Montanaro05885812005-01-16 20:48:27 +00002452- The reconvert.quote function can now emit triple-quoted strings. The
2453 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002454
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002455- ``UserString.MutableString`` now supports negative indices in
2456 ``__setitem__`` and ``__delitem__``
2457
Greg Ward40407942005-03-05 02:53:17 +00002458- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2459 correctly.
2460
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002461- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2462 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2463 character even if the user has passed a size parameter to get a proper
2464 line ending. Remove the special handling of a "\r\n" that has been split
2465 between two lines.
2466
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002467- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2468 about illegal code points. The codec now supports PEP 293 style error
2469 handlers.
2470
Walter Dörwald78a78b02005-09-01 12:04:29 +00002471- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002472 from the input stream, so that the output is a byte string in the correct
2473 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002474
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002475- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2476 considering it exactly like a '*'.
2477
Walter Dörwald007f8df2005-10-09 19:42:27 +00002478- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2479 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002480
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002481- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2482
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002483- Patch #1413711: Certain patterns of differences were making difflib
2484 touch the recursion limit.
2485
Walter Dörwald58917a62006-03-31 15:26:22 +00002486- Bug #947906: An object oriented interface has been added to the calendar
2487 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002488 called as a script (e.g. via ``python -mcalendar``). Localized month and
2489 weekday names can be ouput (even if an exotic encoding is used) using
2490 special classes that use unicode.

Neal Norwitz602d3392006-03-31 08:21:40 +00002495- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2496 by using -mieee gcc option.
2497
Martin v. Löwis86d66262006-02-17 08:40:11 +00002498- Patch #1432345: Make python compile on DragonFly.
2499
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002500- Build support for Win64-AMD64 was added.
2501
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002502- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2503
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002504- Patch #881820: look for openpty and forkpty also in libbsd.
2505
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002506- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2507 The zlib module is now builtin on Windows.
2508
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002509- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2510
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002511- Bug #1189330: configure did not correctly determine the necessary
2512 value of LINKCC if python was built with GCC 4.0.
2513
Trent Mick8321b422005-07-26 02:29:21 +00002514- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2515 vulnerability in zlib 1.2.1 and 1.2.2.
2516
Brett Cannon08cd5982005-04-24 22:26:38 +00002517- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2518 flags that change binary compatibility. Changes were also made to
2519 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002520 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002521
Bob Ippolitoed233462005-03-29 13:47:59 +00002522- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2523 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2524 no longer exists). This configure patch makes things right.
2525
Martin v. Löwise2713be2005-03-08 15:03:08 +00002526- Bug #1158607: Build with --disable-unicode again.
2527
Brett Cannon46d96232005-02-16 00:07:19 +00002528- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2529 defined. Discovered as a result of not being able to build on OS X.
2530
Brett Cannon516592f2004-12-07 00:42:59 +00002531- setup.py now uses the directories specified in LDFLAGS using the -L option
2532 and in CPPFLAGS using the -I option for adding library and include
2533 directories, respectively, for compiling extension modules against. This has
2534 led to the core being compiled using the values in CPPFLAGS. It also removes
2535 the need for the special-casing of both DarwinPorts and Fink for darwin since
2536 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2537 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2538 Fink, ``-I/opt/local/include`` for DarwinPorts).
2539
Brett Cannon43802422005-02-10 20:48:03 +00002540- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2541 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2542 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2543 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002545C API
2546-----
2547
Tim Petersc9d78aa2006-03-26 23:27:58 +00002548- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2549 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2550 is obtained via the ``PyObject_`` family, it must be released via the
2551 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2552 always been officially true, but when Python's small-object allocator was
2553 introduced, an attempt was made to cater to a few extension modules
2554 discovered at the time that obtained memory via ``PyObject_New`` but
2555 released it via ``PyMem_DEL``. It's years later, and if such code still
2556 exists it will fail now (probably with segfaults, but calling wrong
2557 low-level memory management functions can yield many symptoms).
2558
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002559- Added a C API for set and frozenset objects.
2560
Raymond Hettinger66517482004-12-03 11:45:13 +00002561- Removed PyRange_New().
2562
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002563- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2564 mapping argument now. This string is used as a mapping table. Byte values
2565 greater than the length of the string and 0xFFFE are treated as undefined
2566 mappings.
