412Core and builtins
413-----------------
414
Neal Norwitz24b6f202006-09-05 04:43:56 +0000415- Fix infinite recursion when subclassing long and overriding __hash__.
416
417- Fix concatenation (+=) of long strings.
418
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000419- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000420 compared equal or unequal to a string and a UnicodeDecodeError
421 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000422
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000423 Instead, the equal (==) and unequal (!=) comparison operators will
424 now issue a UnicodeWarning and interpret the two objects as
425 unequal. The UnicodeWarning can be filtered as desired using
426 the warning framework, e.g. silenced completely, turned into an
427 exception, logged, etc.
428
429 Note that compare operators other than equal and unequal will still
430 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000431
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000432- Fix segfault when doing string formatting on subclasses of long.
433
434- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
435 with new-style classes.
436
437- Fix bug related to __len__ functions returning negative values with
438 classic classes.
439
440- Patch #1538606, Fix __index__() clipping. There were some problems
441 discovered with the API and how integers that didn't fit into Py_ssize_t
442 were handled. This patch attempts to provide enough alternatives
443 to effectively use __index__.
444
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000445- Bug #1536021: __hash__ may now return long int; the final hash
446 value is obtained by invoking hash on the long int.
447
Thomas Hellerab1049c2006-08-08 17:37:00 +0000448- Bug #1536786: buffer comparison could emit a RuntimeWarning.
449
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000450- Bug #1535165: fixed a segfault in input() and raw_input() when
451 sys.stdin is closed.
452
Thomas Heller74d36f02006-08-04 18:17:40 +0000453- On Windows, the PyErr_Warn function is now exported from
454 the Python dll again.
455
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000456- Bug #1191458: tracing over for loops now produces a line event
457 on each iteration. Fixing this problem required changing the .pyc
458 magic number. This means that .pyc files generated before 2.5c1
459 will be regenerated.
460
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000461- Bug #1333982: string/number constants were inappropriately stored
462 in the byte code and co_consts even if they were not used, ie
463 immediately popped off the stack.
464
Georg Brandle9462c72006-08-04 18:03:37 +0000465- Fixed a reference-counting problem in property().

468Library
469-------
470
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000471- Fix a bug in the ``compiler`` package that caused invalid code to be
472 generated for generator expressions.
473
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000474- The distutils version has been changed to 2.5.0. The change to
475 keep it programmatically in sync with the Python version running
476 the code (introduced in 2.5b3) has been reverted. It will continue
477 to be maintained manually as static string literal.
478
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000479- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000480 and this cannot be converted to the required C type, an exception is
481 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000482 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000483
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000484- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000485 an exception.
486
Tim Peterscbdd3502006-09-05 01:47:53 +0000487- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000488 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000489 workarounds for clocks with low resolution, to stop the code yielding
490 duplicate UUIDs.
491
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000492- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
493 before raising SystemExit, allowing IDLE to honor quit() and exit().
494
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000495- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
496
Georg Brandl7a1af772006-08-14 21:55:28 +0000497- Patch #1536071: trace.py should now find the full module name of a
498 file correctly even on Windows.
499
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000500- logging's atexit hook now runs even if the rest of the module has
501 already been cleaned up.
502
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000503- Bug #1112549, fix DoS attack on cgi.FieldStorage.

Neal Norwitzff4b63b2006-08-04 04:50:21 +0000505- Bug #1531405, format_exception no longer raises an exception if
506 str(exception) raised an exception.
507
Neil Schemenauer06ded092006-08-04 16:20:30 +0000508- Fix a bug in the ``compiler`` package that caused invalid code to be
509 generated for nested functions.

521
Thomas Heller1ce433e2006-08-14 16:20:04 +0000522- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
523 '-no-stack-protector' compiler flag for OpenBSD has been removed.
524
Thomas Heller86720042006-08-14 11:17:48 +0000525- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
526 uses the _as_parameter_ attribute when objects are passed to foreign
527 function calls. The ctypes version number was changed to 1.0.1.
528
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000529- Bug #1530559, struct.pack raises TypeError where it used to convert.
530 Passing float arguments to struct.pack when integers are expected
531 now triggers a DeprecationWarning.

581Core and builtins
582-----------------
583
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000584- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000585 returned a long (see PEP 353).
586
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000587- Bug #1515471: string.replace() accepts character buffers again.
588
Neal Norwitz07aadb12006-07-30 06:55:48 +0000589- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
590 This provides the proper warning for struct.pack().
591 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
592
Neal Norwitz0d62a062006-07-30 06:53:31 +0000593- Patch #1531113: Fix augmented assignment with yield expressions.
594 Also fix a SystemError when trying to assign to yield expressions.
595
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000596- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
597 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
598 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
599 excessive filesystem operations during imports.
600
Tim Petersbc24eee2006-07-27 01:14:53 +0000601- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
602 operations on signed longs that are formally undefined by C.
603 Unfortunately, at least one compiler now cares about that, so complicated
604 the code to make that compiler happy again.
605
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000606- Bug #1524310: Properly report errors from FindNextFile in os.listdir.

Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000621- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000622 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000623 This means that .pyc files generated before 2.5b3 will be regenerated.

Tim Peters112aad32006-07-19 00:03:19 +0000625- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000626 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000627 new ``sys._current_frames()`` returns a dictionary with one entry,
628 mapping the faux "thread id" 0 to the current frame.

634-------
635
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000636- Correction of patch #1455898: In the mbcs decoder, set final=False
637 for stream decoder, but final=True for the decode function.
638
Georg Brandl07fec3a2006-08-01 18:49:24 +0000639- os.urandom no longer masks unrelated exceptions like SystemExit or
640 KeyboardInterrupt.
641
Tim Peters4643c2f2006-08-10 22:45:34 +0000642- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000643 shutil.copytree on Windows
644
Georg Brandle34ac7c2006-07-30 11:07:23 +0000645- Bug #1002398: The documentation for os.path.sameopenfile now correctly
646 refers to file descriptors, not file objects.
647
Tim Peterscbdd3502006-09-05 01:47:53 +0000648- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000649 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000650 #1513611, and probably others.
651
Georg Brandledd9b0d2006-07-29 09:33:26 +0000652- Bug #1441397: The compiler module now recognizes module and function
653 docstrings correctly as it did in Python 2.4.
654
Tim Peters6f681472006-07-27 23:44:37 +0000655- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
656 lost that tests are sorted by name before being run. This rarely
657 matters for well-written tests, but can create baffling symptoms if
658 side effects from one test to the next affect outcomes. ``DocTestFinder``
659 has been changed to sort the list of tests it returns.
660
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000661- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000662 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000663
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000664- Bug #978833: Really close underlying socket in _socketobject.close.
665
Georg Brandldb232dc2006-08-20 13:15:43 +0000666- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
667 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000668
Georg Brandlcf0c1722006-07-26 07:23:32 +0000669- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
670 to recursive calls and call it with the failing package name.
671
Martin v. Löwis0b483032006-07-25 09:53:12 +0000672- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
673
Georg Brandlc13c34c2006-07-24 14:09:56 +0000674- Patch #1515343: Fix printing of deprecated string exceptions with a
675 value in the traceback module.
676
Greg Ward48fae7a2006-07-23 16:05:51 +0000677- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
678
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000679- Patch #1524429: Use repr() instead of backticks in Tkinter again.
680
Brett Cannoncaebe222006-07-18 04:41:36 +0000681- Bug #1520914: Change time.strftime() to accept a zero for any position in its
682 argument tuple. For arguments where zero is illegal, the value is forced to
683 the minimum value that is correct. This is to support an undocumented but
684 common way people used to fill in inconsequential information in the time
685 tuple pre-2.4.
686
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000687- Patch #1220874: Update the binhex module for Mach-O.
688
Barry Warsawb110bad2006-07-21 14:51:07 +0000689- The email package has improved RFC 2231 support, specifically for
690 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
691 (name*0=<blah>) parameter continuations. This may change the types of
692 values returned from email.message.Message.get_param() and friends.
693 Specifically in some cases where non-encoded continuations were used,
694 get_param() used to return a 3-tuple of (None, None, string) whereas now it
695 will just return the string (since non-encoded continuations don't have
696 charset and language parts).
697
698 Also, whereas % values were decoded in all parameter continuations, they are
699 now only decoded in encoded parameter parts.
700
Ronald Oussoren3075e162006-07-25 20:28:55 +0000701- Bug #1517990: IDLE keybindings on MacOS X now work correctly
702
703- Bug #1517996: IDLE now longer shows the default Tk menu when a
704 path browser, class browser or debugger is the frontmost window on MacOS X
705
Barry Warsaw00decd72006-07-27 23:43:15 +0000706- Patch #1520294: Support for getset and member descriptors in types.py,
707 inspect.py, and pydoc.py. Specifically, this allows for querying the type
708 of an object against these built-in types and more importantly, for getting
709 their docstrings printed in the interactive interpreter's help() function.

714
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000715- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
716 a socket operation on a socket with a timeout, the exception will be
717 caught correctly. Previously, the exception was not caught.
718
Thomas Heller1393d6a2006-07-28 21:43:20 +0000719- Patch #1529514: The _ctypes extension is now compiled on more
720 openbsd target platforms.
721
Tim Peters9cab5932006-07-28 00:30:00 +0000722- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
723 a memory leak, affecting pickles and deep copies.
724
Tim Petersbc24eee2006-07-27 01:14:53 +0000725- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000726 Paul Eggert.
727
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000728- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
729
Thomas Hellerce049a02006-07-14 17:51:14 +0000730- Patch #1521817: Index range checking on ctypes arrays containing
731 exactly one element enabled again. This allows iterating over these
732 arrays, without the need to check the array size before.
733
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000734- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000735 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000736 /dev/null in certain cases; this is now fixed.
737
Thomas Heller47d7a062006-07-12 08:43:47 +0000738- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
739 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000740
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000741- Because of a misspelled preprocessor symbol, ctypes was always
742 compiled without thread support; this is now fixed.
743
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000744- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
745 methods now allow their database parameter to be None as the
746 sleepycat API allows.
747
Matt Flemingec926502006-07-28 11:27:27 +0000748- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
749 bluetooth API compared with Linux and FreeBSD.
750
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000751Tests
752-----
753
754- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
755 how long the test file should take to play. Now accepts taking 2.93 secs
756 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
757
Georg Brandl4793aa32006-07-28 18:31:39 +0000758- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
759 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
760 run via ``regrtest.py``. Now they do.

769
770- PythonLauncher now works correctly when the path to the script contains
771 characters that are treated specially by the shell (such as quotes).
772
773- Bug #1527397: PythonLauncher now launches scripts with the working directory
774 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000775 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000776 expect.

784Core and builtins
785-----------------
786
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000787- Bug #1441486: The literal representation of -(sys.maxint - 1)
788 again evaluates to a int object, not a long.
789
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000790- Bug #1501934: The scope of global variables that are locally assigned
791 using augmented assignment is now correctly determined.
792
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000793- Bug #927248: Recursive method-wrapper objects can now safely
794 be released.
795
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000796- Bug #1417699: Reject locale-specific decimal point in float()
797 and atof().
798
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000799- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
800 omit a default "error" argument for NULL pointer. This allows
801 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000802
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000803- Bug #1519018: 'as' is now validated properly in import statements.
804
Neal Norwitz28746ab2006-07-09 22:14:42 +0000805- On 64 bit systems, int literals that use less than 64 bits are
806 now ints rather than longs.
807
Neal Norwitzed657552006-07-10 00:04:44 +0000808- Bug #1512814, Fix incorrect lineno's when code at module scope
809 started after line 256.
810
Tim Peters32a83612006-07-10 21:08:24 +0000811- New function ``sys._current_frames()`` returns a dict mapping thread
812 id to topmost thread stack frame. This is for expert use, and is
813 especially useful for debugging application deadlocks. The functionality
814 was previously available in Fazal Majid's ``threadframe`` extension
815 module, but it wasn't possible to do this in a wholly threadsafe way from
816 an extension.

Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000847- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000848 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000849
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000850- Bug #1514703: Only setup canvas window in turtle when the canvas
851 is created.
852
Martin v. Löwis7596e832006-07-01 15:33:37 +0000853- Bug #1513223: .close() of a _socketobj now releases the underlying
854 socket again, which then gets closed as it becomes unreferenced.

857 attribute values.
858
859- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
860 sgmllib ('[' and ']' were not accepted).

Georg Brandl1be63af2006-06-28 20:23:25 +0000862- Fix a bug in the turtle module's end_fill function.
863
Brett Cannon53ab5b72006-06-22 16:49:14 +0000864- Bug #1510580: The 'warnings' module improperly required that a Warning
865 category be either a types.ClassType and a subclass of Warning. The proper
866 check is just that it is a subclass with Warning as the documentation states.
867
Georg Brandlad29e632006-06-21 17:45:17 +0000868- The compiler module now correctly compiles the new try-except-finally
869 statement (bug #1509132).
870
Neal Norwitz60373cd2006-06-22 06:30:50 +0000871- The wsgiref package is now installed properly on Unix.
872
Vinay Sajip28e57612006-07-01 10:45:20 +0000873- A bug was fixed in logging.config.fileConfig() which caused a crash on
874 shutdown when fileConfig() was called multiple times.
875
Gerhard Häring762fbd32006-07-02 17:48:30 +0000876- The sqlite3 module did cut off data from the SQLite database at the first
877 null character before sending it to a custom converter. This has been fixed
878 now.

Tim Peters112aad32006-07-19 00:03:19 +0000883- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
884 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
885 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000886
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000887- Assigning None to pointer type fields in ctypes structures possible
888 overwrote the wrong fields, this is fixed now.
889
890- Fixed a segfault in _ctypes when ctypes.wintypes were imported
891 on non-Windows platforms.
892
893- Bug #1518190: The ctypes.c_void_p constructor now accepts any
894 integer or long, without range checking.
895
896- Patch #1517790: It is now possible to use custom objects in the ctypes
897 foreign function argtypes sequence as long as they provide a from_param
898 method, no longer is it required that the object is a ctypes type.
899
900- The '_ctypes' extension module now works when Python is configured
901 with the --without-threads option.
902
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000903- Bug #1513646: os.access on Windows now correctly determines write

Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000920 Previously, the slight difference could cause compilation errors of the
921 'zlib' module on systems with more than one version of zlib.
922
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000923- The MSI compileall step was fixed to also support a TARGETDIR
924 with spaces in it.
925
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000926- Bug #1517388: sqlite3.dll is now installed on Windows independent
927 of Tcl/Tk.
928
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000929- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000930 trying to be installed even though it's empty.

942 documentation for the warnings module.
943
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000944- Patch #1509163: MS Toolkit Compiler no longer available.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000953
954Core and builtins
955-----------------
956
Georg Brandla56b9152006-06-19 06:35:54 +0000957- Patch #1507676: Error messages returned by invalid abstract object operations
958 (such as iterating over an integer) have been improved and now include the
959 type of the offending object to help with debugging.
960
Brett Cannonea3912b2006-06-13 21:46:41 +0000961- Bug #992017: A classic class that defined a __coerce__() method that returned
962 its arguments swapped would infinitely recurse and segfault the interpreter.
963
Neal Norwitz909eb122006-06-12 02:13:21 +0000964- Fix the socket tests so they can be run concurrently.
965
Neal Norwitzb9845e72006-06-12 02:11:18 +0000966- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000967 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000968
Brett Cannon22565aa2006-06-09 22:31:23 +0000969- Bug #532646: object.__call__() will continue looking for the __call__
970 attribute on objects until one without one is found. This leads to recursion
971 when you take a class and set its __call__ attribute to an instance of the
972 class. Originally fixed for classic classes, but this fix is for new-style.
973 Removes the infinite_rec_3 crasher.
974
Georg Brandl24250812006-06-09 18:45:48 +0000975- The string and unicode methods startswith() and endswith() now accept
976 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
977
Brett Cannonde3b0522006-06-08 17:00:45 +0000978- Buffer objects, at the C level, never used the char buffer
979 implementation even when the char buffer for the wrapped object was
980 explicitly requested (originally returned the read or write buffer).
981 Now a TypeError is raised if the char buffer is not present but is
982 requested.
983
Georg Brandlddbaa662006-06-04 21:56:52 +0000984- Patch #1346214: Statements like "if 0: suite" are now again optimized
985 away like they were in Python 2.4.
986
Georg Brandlb7c8f542006-05-27 12:30:25 +0000987- Builtin exceptions are now full-blown new-style classes instead of
988 instances pretending to be classes, which speeds up exception handling
989 by about 80% in comparison to 2.5a2.
990
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000991- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
992 Unicode 4.1.
993
Georg Brandlf4ef1162006-05-26 18:03:31 +0000994- Patch #921466: sys.path_importer_cache is now used to cache valid and
995 invalid file paths for the built-in import machinery which leads to
996 fewer open calls on startup.
997
Tim Peters696cf432006-05-24 21:10:40 +0000998- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
999 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1000 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1001 the number of input digits (it was and remains linear-time for bases
1002 2, 4, 8, 16 and 32).
1003
Tim Petersb713ec22006-05-23 18:45:30 +00001004- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1005 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1006 an integer close to ``sys.maxint``. This was repaired by patch
1007 #1335972, which also gives a nice speedup.
1008
Richard Jonescebbefc2006-05-23 18:28:17 +00001009- Patch #1337051: reduced size of frame objects.
1010
1011- PyErr_NewException now accepts a tuple of base classes as its
1012 "base" parameter.
1013
Richard Jones7c88dcc2006-05-23 10:37:38 +00001014- Patch #876206: function call speedup by retaining allocated frame
1015 objects.
1016
Georg Brandl7b90e162006-05-18 07:01:27 +00001017- Bug #1462152: file() now checks more thoroughly for invalid mode
1018 strings and removes a possible "U" before passing the mode to the
1019 C library function.
1020
Neal Norwitz1004a532006-05-15 07:17:23 +00001021- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1022
Neal Norwitz373f0a72006-05-15 07:04:36 +00001023- Bug #1487966: Fix SystemError with conditional expression in assignment
1024
Martin v. Löwis879768d2006-05-11 13:28:43 +00001025- WindowsError now has two error code attributes: errno, which carries
1026 the error values from errno.h, and winerror, which carries the error
1027 values from winerror.h. Previous versions put the winerror.h values
1028 (from GetLastError()) into the errno attribute.
1029
Martin v. Löwis77736712006-05-04 05:51:03 +00001030- Patch #1475845: Raise IndentationError for unexpected indent.
1031
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001032- Patch #1479181: split open() and file() from being aliases for each other.
1033
Tim Peters44bd9862006-06-01 13:49:23 +00001034- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1035 methods were always silently ignored by dictionaries when comparing keys.
1036 They are now passed through (except when using the C API function
1037 ``PyDict_GetItem()``, whose semantics did not change).
1038
1039- Bug #1456209: In some obscure cases it was possible for a class with a
1040 custom ``__eq__()`` method to confuse dict internals when class instances
1041 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1042 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001044Extension Modules
1045-----------------
1046
Trent Mick960a3f82006-06-28 20:30:41 +00001047- Bug #1295808: expat symbols should be namespaced in pyexpat
1048
1049- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1050
Brett Cannon6ee7d012006-06-08 16:23:04 +00001051- Change binascii.hexlify to accept a read-only buffer instead of only a char
1052 buffer and actually follow its documentation.
1053
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001054- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1055
Nick Coghlanc649ec52006-05-29 12:43:05 +00001056- Patch #1478788 (modified version): The functional extension module has
1057 been renamed to _functools and a functools Python wrapper module added.
1058 This provides a home for additional function related utilities that are
1059 not specifically about functional programming. See PEP 309.
1060
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001061- Patch #1493701: performance enhancements for struct module.
1062
Georg Brandl378d5922006-05-17 14:26:50 +00001063- Patch #1490224: time.altzone is now set correctly on Cygwin.
1064
Georg Brandl8d3342b2006-05-16 07:38:27 +00001065- Patch #1435422: zlib's compress and decompress objects now have a
1066 copy() method.
1067
Andrew MacIntyre92913322006-06-13 15:04:24 +00001068- Patch #1454481: thread stack size is now tunable at runtime for thread
1069 enabled builds on Windows and systems with Posix threads support.
1070
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001071- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1072 (up to the system limit of 32K characters).
1073
1074- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1075 As a result, these functions now raise WindowsError instead of OSError.
1076
Tim Peters7a822da2006-05-25 21:50:17 +00001077- ``time.clock()`` on Win64 should use the high-performance Windows
1078 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1079 Windows platforms).
1080
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001081- Calling Tk_Init twice is refused if the first call failed as that
1082 may deadlock.
1083
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001084- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1085 accept it without potentially using an uninitialized pointer.
1086
1087- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1088 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1089 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001090
Gregory P. Smith372b5832006-06-05 18:48:21 +00001091- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001092 [pybsddb project SF patch number 1466734]
1093
Gregory P. Smith372b5832006-06-05 18:48:21 +00001094- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1095 parameter is supplied. [SF pybsddb bug #1477863]
1096
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001097- bsddb: the __len__ method of a DB object has been fixed to return correct
1098 results. It could previously incorrectly return 0 in some cases.
1099 Fixes SF bug 1493322 (pybsddb bug 1184012).
1100
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001101- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1102 aborts the db transaction safely when a modifier callback fails.
1103 Fixes SF python patch/bug #1408584.
1104
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001105- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001106 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001107 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1108 database calls that would previously deadlock. [SF python bug #775414]
1109
Vinay Sajip28e57612006-07-01 10:45:20 +00001110- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001111
Walter Dörwald4994d952006-06-19 08:07:50 +00001112- Patch #1506645: add Python wrappers for the curses functions
1113 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001114

1116-------
1117
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001118- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1119 functions.
1120
Martin v. Löwis3798da02006-06-17 18:44:27 +00001121- Patch #812986: Update turtle output even if not tracing.
1122
Vinay Sajip28e57612006-07-01 10:45:20 +00001123- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001124 Tkinter.BaseWidget.
1125
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001126- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1127
Martin v. Löwis337487e2006-06-17 09:15:14 +00001128- Patch #763580: Add name and value arguments to Tkinter variable
1129 classes.
1130
Georg Brandl83cc0d02006-06-14 08:50:03 +00001131- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1132 mime.types file for determining MIME types.
1133
Georg Brandl2605ca82006-06-14 06:08:31 +00001134- Bug #1339007: Shelf objects now don't raise an exception in their
1135 __del__ method when initialization failed.
1136
Martin v. Löwisd8251432006-06-14 05:21:04 +00001137- Patch #1455898: The MBCS codec now supports the incremental mode for
1138 double-byte encodings.
1139
Tim Peters43898b42006-06-14 04:09:25 +00001140- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1141 guarantee that adjacent triples in the return list always describe
1142 non-adjacent blocks. Previously, a pair of matching blocks could end
1143 up being described by multiple adjacent triples that formed a partition
1144 of the matching pair.
1145
Greg Ward0e0c9f42006-06-11 16:24:11 +00001146- Bug #1498146: fix optparse to handle Unicode strings in option help,
1147 description, and epilog.
1148
Greg Wardd1c797e2006-06-11 14:42:41 +00001149- Bug #1366250: minor optparse documentation error.
1150
Greg Ward7f547402006-06-11 00:40:49 +00001151- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1152 clarify docs.
1153
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001154- The wsgiref package has been added to the standard library.
1155
Nick Coghlan676725d2006-06-08 13:54:49 +00001156- The functions update_wrapper() and wraps() have been added to the functools
1157 module. These make it easier to copy relevant metadata from the original
1158 function when writing wrapper functions.
1159
Tim Petersd6a9eef2006-06-05 01:48:21 +00001160- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1161 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001162
Martin v. Löwis3f767792006-06-04 19:36:28 +00001163- Patch #1359618: Speed up charmap encoder by using a trie structure
1164 for lookup.
1165
Tim Petersd609b1a2006-06-02 23:22:51 +00001166- The functions in the ``pprint`` module now sort dictionaries by key
1167 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1168 if and only if its display required more than one line, although that
1169 wasn't documented. The new behavior increases predictability; e.g.,
1170 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1171
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001172- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1173 (thanks for J. J. Lee).
1174
Georg Brandl2b330372006-05-28 20:23:12 +00001175- Patch #1496206: improve urllib2 handling of passwords with respect to
1176 default HTTP and HTTPS ports.
1177
George Yoshidaf3c65de2006-05-28 16:39:09 +00001178- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1179
Bob Ippolito7298f272006-05-23 18:43:47 +00001180- Patch #1281707: speed up gzip.readline.
1181
Georg Brandlb89316f2006-05-17 15:51:16 +00001182- Patch #1180296: Two new functions were added to the locale module:
1183 format_string() to get the effect of "format % items" but locale-aware,
1184 and currency() to format a monetary number with currency sign.
1185
Georg Brandle3a25832006-05-17 14:56:04 +00001186- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1187 and several features added, such as speed and geometry control.
1188
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001189- Patch #1488881: add support for external file objects in bz2 compressed
1190 tarfiles.
1191
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001192- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1193 stdout arguments, making it possible to redirect input and output
1194 for remote debugging.
1195
1196- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1197 a couple of issues, notably handling of long file names using the
1198 GNU LONGNAME extension.
1199
1200- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1201 new flag when ``name`` is already the name of an option flag.
1202
1203- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1204 package.
1205
1206- Patch #1472854: make the rlcompleter.Completer class usable on non-
1207 UNIX platforms.
1208

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001242What's New in Python 2.5 alpha 2?
1243=================================
1244
1245*Release date: 27-APR-2006*
1246
1247Core and builtins
1248-----------------
1249
Thomas Heller1b046642006-04-18 18:51:06 +00001250- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1251 by converting these apis from macros into exported functions again:
1252
1253 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1254 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1255 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1256 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1257 PyRun_String Py_CompileString
1258
Martin v. Löwis45294a92006-04-18 06:24:08 +00001259- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1260
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001261- All uses of PyStructSequence_InitType have been changed to initialize
1262 the type objects only once, even if the interpreter is initialized
1263 multiple times.
1264
Neal Norwitz61546162006-04-14 05:20:28 +00001265- Bug #1454485, array.array('u') could crash the interpreter. This was
1266 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1267 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1268
1269- Py_UNICODE is unsigned. It was always documented as unsigned, but
1270 due to a bug had a signed value in previous versions.
1271
Tim Peters3a5e8b12006-04-11 01:44:07 +00001272- Patch #837242: ``id()`` of any Python object always gives a positive
1273 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1274 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001275 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001276 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001277
Tim Peters3a5e8b12006-04-11 01:44:07 +00001278 def __hash__(self):
1279 return id(self) # WRONG
1280
1281 because a hash result must be a (short) Python int but it was always
1282 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001283 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001284 was always usable as a hash value before this patch. That's no longer
1285 necessarily so.
1286
1287- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001288 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001289 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001290 #1454844)
1291
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001292- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1293 involving generators that have paused outside of any ``try`` or ``with``
1294 blocks. (In 2.5a1, a paused generator that was part of a reference
1295 cycle could not be garbage collected, regardless of whether it was
1296 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001297
Anthony Baxter51bcb682006-04-05 14:51:42 +00001298Extension Modules

1300
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001301- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1302 is a macro.
1303
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001304- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1305 fails with an error condition.
1306
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001307- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1308
1309- Bug #1117761: bsddb.*open() no longer raises an exception when using
1310 the cachesize parameter.
1311
1312- Bug #1149413: bsddb.*open() no longer raises an exception when using
1313 a temporary db (file=None) with the 'n' flag to truncate on open.
1314
1315- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1316 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001317
Armin Rigoa9017c32006-04-19 11:50:27 +00001318- Patch #1062014: AF_UNIX sockets under Linux have a special
1319 abstract namespace that is now fully supported.
1320
Anthony Baxter51bcb682006-04-05 14:51:42 +00001321Library
1322-------
1323
Peter Astrand7d1d4362006-07-14 14:04:45 +00001324- Bug #1223937: subprocess.CalledProcessError reports the exit status
1325 of the process using the returncode attribute, instead of
1326 abusing errno.
1327
Tim Peters711bf302006-04-25 03:31:36 +00001328- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1329 a doctest to be skipped (the code is not run, and the expected output
1330 or exception is ignored).
1331
Nick Coghlanda2268f2006-04-24 04:37:15 +00001332- Fixed contextlib.nested to cope with exceptions being raised and
1333 caught inside exit handlers.
1334
Greg Wardab05edc2006-04-23 03:47:58 +00001335- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1336 hex, octal, or binary; add ``append_const`` action; keep going if
1337 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1338 added ``epilog`` for better help generation).
1339
Tim Peters21fbd572006-04-21 21:18:10 +00001340- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1341 called from a thread spawned as a side effect of importing a module.
1342
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001343- The pydoc module now supports documenting packages contained in
1344 .zip or .egg files.
1345
1346- The pkgutil module now has several new utility functions, such
1347 as ``walk_packages()`` to support working with packages that are either
1348 in the filesystem or zip files.
1349
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001350- The mailbox module can now modify and delete messages from
1351 mailboxes, in addition to simply reading them. Thanks to Gregory
1352 K. Johnson for writing the code, and to the 2005 Google Summer of
1353 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001354
Tim Petersc7605f22006-04-17 21:12:33 +00001355- The ``__del__`` method of class ``local`` in module ``_threading_local``
1356 returned before accomplishing any of its intended cleanup.
1357
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001358- Patch #790710: Add breakpoint command lists in pdb.
1359
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001360- Patch #1063914: Add Tkinter.Misc.clipboard_get().
1361
Martin v. Löwis4b501e62006-04-15 08:41:11 +00001362- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1363
Anthony Baxtere29002c2006-04-12 12:07:31 +00001364- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1365 Windows. Bug #1469163.
1366
Phillip J. Eby47032112006-04-11 01:07:43 +00001367- The warnings, linecache, inspect, traceback, site, and doctest modules
1368 were updated to work correctly with modules imported from zipfiles or
1369 via other PEP 302 __loader__ objects.
1370
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001371- Patch #1467770: Reduce usage of subprocess._active to processes which
1372 the application hasn't waited on.
1373
Martin v. Löwisb04dee92006-04-10 08:34:21 +00001374- Patch #1462222: Fix Tix.Grid.
1375
Neal Norwitza31bf182006-04-09 03:35:43 +00001376- Fix exception when doing glob.glob('anything*/')
1377
Skip Montanaro262fb922006-04-21 02:31:07 +00001378- The pstats.Stats class accepts an optional stream keyword argument to
1379 direct output to an alternate file-like object.
1380
Anthony Baxter51bcb682006-04-05 14:51:42 +00001381Build
1382-----
1383
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001384- The Makefile now has a reindent target, which runs reindent.py on
1385 the library.
1386
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001387- Patch #1470875: Building Python with MS Free Compiler
1388
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001389- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001390
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001391- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1392 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001393 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001394 CXX from --with-cxx-main, see description in README.
1395
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001396- Patch #1429775: Link extension modules with the shared libpython.
1397
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001398- Fixed a libffi build problem on MIPS systems.
1399
Tim Peters8931ff12006-05-13 23:28:20 +00001400- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1401 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1402 and "%zu" for unsigned integers of type ``size_t``.
1403
Anthony Baxter51bcb682006-04-05 14:51:42 +00001404Tests
1405-----
1406
Nick Coghlanda2268f2006-04-24 04:37:15 +00001407- test_contextlib now checks contextlib.nested can cope with exceptions
1408 being raised and caught inside exit handlers.
1409
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001410- test_cmd_line now checks operation of the -m and -c command switches
1411
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001412- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1413 it separately and by hand. It also wasn't cleaning up its changes to
1414 the current Decimal context.
1415
Thomas Woutersabd08882006-04-26 15:53:30 +00001416- regrtest.py now has a -M option to run tests that test the new limits of
1417 containers, on 64-bit architectures. Running these tests is only sensible
1418 on 64-bit machines with more than two gigabytes of memory. The argument
1419 passed is the maximum amount of memory for the tests to use.
1420
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001421Tools

1423
1424- Added the Python benchmark suite pybench to the Tools/ directory;
1425 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001427Documentation
1428-------------
1429
Tim Petersb06d28c2006-05-12 01:57:59 +00001430- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1431
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001432- PEP 343: Added Context Types section to the library reference
1433 and attempted to bring other PEP 343 related documentation into
1434 line with the implementation and/or python-dev discussions.
1435
Tim Peters8dc73d22006-04-24 02:03:16 +00001436- Bug #1337990: clarified that ``doctest`` does not support examples
1437 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001440What's New in Python 2.5 alpha 1?
1441=================================
1442
Anthony Baxterebed3f62006-04-03 15:03:44 +00001443*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001444
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001445Core and builtins
1446-----------------
1447
Nick Coghlan43832302006-04-23 17:04:07 +00001448- PEP 338: -m command line switch now delegates to runpy.run_module
1449 allowing it to support modules in packages and zipfiles
1450
Martin v. Löwisc661b882006-04-20 04:54:23 +00001451- On Windows, .DLL is not an accepted file name extension for
1452 extension modules anymore; extensions are only found if they
1453 end in .PYD.
1454
Martin v. Löwisea62d252006-04-03 10:56:49 +00001455- Bug #1421664: sys.stderr.encoding is now set to the same value as
1456 sys.stdout.encoding.
1457
Neal Norwitz92e212f2006-04-03 04:48:37 +00001458- __import__ accepts keyword arguments.
1459
Georg Brandlccadf842006-03-31 18:54:53 +00001460- Patch #1460496: round() now accepts keyword arguments.
1461
Anthony Baxter262c00a2006-03-30 10:53:17 +00001462- Fixed bug #1459029 - unicode reprs were double-escaped.
1463
Hye-Shik Changd478f342006-03-23 12:32:36 +00001464- Patch #1396919: The system scope threads are reenabled on FreeBSD
1465 5.4 and later versions.
1466
Neal Norwitze98ccf62006-03-23 05:39:47 +00001467- Bug #1115379: Compiling a Unicode string with an encoding declaration
1468 now gives a SyntaxError.
1469
Georg Brandlabd1ff82006-03-18 07:59:59 +00001470- Previously, Python code had no easy way to access the contents of a
1471 cell object. Now, a ``cell_contents`` attribute has been added
1472 (closes patch #1170323).
1473
Tim Peterscf79aac2006-03-16 01:14:46 +00001474- Patch #1123430: Python's small-object allocator now returns an arena to
1475 the system ``free()`` when all memory within an arena becomes unused
1476 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1477 freed. Some applications will see a drop in virtual memory size now,
1478 especially long-running applications that, from time to time, temporarily
1479 use a large number of small objects. Note that when Python returns an
1480 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001481 platform C library will in turn return that memory to the operating system.
1482 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001483 appears to be effective at least on Microsoft C and gcc-based systems.
1484 Thanks to Evan Jones for hard work and patience.
1485
Georg Brandl533ff6f2006-03-08 18:09:27 +00001486- Patch #1434038: property() now uses the getter's docstring if there is
1487 no "doc" argument given. This makes it possible to legitimately use
1488 property() as a decorator to produce a read-only property.
1489
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001490- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1491 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1492 of requiring an int or long in slicing and a few other contexts, enabling
1493 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1494
Neal Norwitz995acdf2006-03-07 05:01:00 +00001495- Fixed various bugs reported by Coverity's Prevent tool.
1496
Brett Cannonbf364092006-03-01 04:25:17 +00001497- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1498 new exception base class, BaseException, which has a new message attribute.
1499 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1500 Raising a string exception now raises a DeprecationWarning.
1501
Thomas Woutersfb609f42006-02-28 16:37:25 +00001502- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1503 explicitly relative, using 'from .module import name' to mean 'from the same
1504 package as this module is in. Imports without dots still default to the
1505 old relative-then-absolute, unless 'from __future__ import
1506 absolute_import' is used.
1507
Brett Cannona7446e32006-02-27 23:39:10 +00001508- Properly check if 'warnings' raises an exception (usually when a filter set
1509 to "error" is triggered) when raising a warning for raising string
1510 exceptions.
1511
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001512- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001513 The name was removed from Include/code.h.
1514
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001515- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001516
Guido van Rossum1968ad32006-02-25 22:38:04 +00001517- Patch 1433928:
1518 - The copy module now "copies" function objects (as atomic objects).
1519 - dict.__getitem__ now looks for a __missing__ hook before raising
1520 KeyError.
1521
Tim Peters84ef21c2006-02-28 20:39:06 +00001522- PEP 343: with statement implemented. Needs ``from __future__ import
1523 with_statement``. Use of 'with' as a variable will generate a warning.
1524 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001525 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001526 The following objects have __context__ methods:
1527 - The built-in file type.
1528 - The thread.LockType type.
1529 - The following types defined by the threading module:
1530 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1531 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001532
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001533- Fix the encodings package codec search function to only search
1534 inside its own package. Fixes problem reported in patch #1433198.
1535
1536 Note: Codec packages should implement and register their own
1537 codec search function. PEP 100 has the details.
1538
Tim Peters9ea89d22006-06-04 03:26:02 +00001539- PEP 353: Using ``Py_ssize_t`` as the index type.
1540
1541- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1542 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1543 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1544 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1545 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001546
Neal Norwitzfc76d632006-01-10 06:03:13 +00001547- Patch #1400181, fix unicode string formatting to not use the locale.
1548 This is how string objects work. u'%f' could use , instead of .
1549 for the decimal point. Now both strings and unicode always use periods.
1550
Neal Norwitz671b9e32006-01-09 07:07:12 +00001551- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1552 configure would break checking curses.h.
1553
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001554- Bug #959576: The pwd module is now builtin. This allows Python to be
1555 built on UNIX platforms without $HOME set.
1556
Neal Norwitzc10978f2005-12-19 06:07:16 +00001557- Bug #1072182, fix some potential problems if characters are signed.
1558
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001559- Bug #889500, fix line number on SyntaxWarning for global declarations.
1560
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001561- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1562
Neal Norwitze7214a12005-12-18 05:03:17 +00001563- Support for converting hex strings to floats no longer works.
1564 This was not portable. float('0x3') now raises a ValueError.
1565
Barry Warsaw2a38a862005-12-18 01:27:35 +00001566- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001567 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001568 is now displayed in interactive prompt banner.
1569
Georg Brandlfa166682005-12-17 21:45:17 +00001570- Implementation of PEP 341 - Unification of try/except and try/finally.
1571 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001572 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001573
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001574- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1575 now encodes backslash correctly.
1576
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001577- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1578
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001579- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001580 and long longs.
1581
Neal Norwitz67715f02005-11-09 06:59:35 +00001582- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001583 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001584 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001585
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001586- Replaced most Unicode charmap codecs with new ones using the
1587 new Unicode translate string feature in the builtin charmap
1588 codec; the codecs were created from the mapping tables available
1589 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1590 encodings now include a mapping for the Apple logo)
1591
Tim Peterse3547fd2005-12-16 23:13:57 +00001592- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001593
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001594- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001595
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001596- A new AST parser implementation was completed. The abstract
1597 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001598 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001599
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001600- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001601 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1602
Neal Norwitz708e51a2005-10-03 04:48:15 +00001603- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1604
Neal Norwitz11bd1192005-10-03 00:54:56 +00001605- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1606 Provide a warning when a directory is passed on the command line.
1607
Neal Norwitz40d37812005-10-02 01:48:49 +00001608- Fix segfault with invalid coding.
1609
1610- SF bug #772896: unknown encoding results in MemoryError.
1611
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001612- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001613 supported a __len__() method which evaluated to False when the iterator
1614 was empty.
1615
Guido van Rossum630db602005-09-20 18:49:54 +00001616- On 64-bit platforms, when __len__() returns a value that cannot be
1617 represented as a C int, raise OverflowError.
1618
Skip Montanarof8948ca2005-09-19 03:54:46 +00001619- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001620 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001621
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001622- SF bug #893549: parsing keyword arguments was broken with a few format
1623 codes.
1624
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001625- Changes donated by Elemental Security to make it work on AIX 5.3
1626 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1627 bug #105470: test_pwd fails on 64bit system (Opteron).
1628
Guido van Rossum539c6622005-09-14 17:49:54 +00001629- Changes donated by Elemental Security to make it work on HP-UX 11 on
1630 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1631
Georg Brandl4550b8d2005-08-26 06:43:52 +00001632- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001633 (fixes bug #1119418).
1634
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001635- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1636
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001637- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1638 exceptions that cause a function to exit.
1639
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001640- The implementation of set() and frozenset() was revised to use its
1641 own internal data structure. Memory consumption is reduced by 1/3
1642 and there are modest speed-ups as well. The API is unchanged.
1643
Tim Petersde7990b2005-07-17 23:45:23 +00001644- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1645
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001646- SF bug #1229429: PyObject_CallMethod failed to decrement some
1647 reference counts in some error exit cases.
1648
Tim Petersecc6e6a2005-07-10 22:30:55 +00001649- SF bug #1185883: Python's small-object memory allocator took over
1650 a block managed by the platform C library whenever a realloc specified
1651 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001652 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001653 portable way to copy data from the C-managed block into Python's
1654 small-object space without risking a memory fault. Python's small-object
1655 realloc now leaves such blocks under the control of the platform C
1656 realloc.
1657
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001658- SF bug #1232517: An overflow error was not detected properly when
1659 attempting to convert a large float to an int in os.utime().
1660
Raymond Hettinger3296e692005-06-29 23:29:56 +00001661- SF bug #1224347: hex longs now print with lowercase letters just
1662 like their int counterparts.
1663
Michael W. Hudson188d4362005-06-20 16:52:57 +00001664- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1665 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1666 interpreter states; back out that fix and do a better job (see
1667 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1668 for a longer write-up of the problem).
1669
Michael W. Hudsondf888462005-06-03 14:41:55 +00001670- SF patch #1180995: marshal now uses a binary format by default when
1671 serializing floats.
1672
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001673- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1674 the routines that promise to produce IEEE 754 binary representations
1675 of floats now simply copy bytes around.
1676
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001677- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1678 278.
1679
Brett Cannonc3647ac2005-04-26 03:45:26 +00001680- patch #1109424: int, long, float, complex, and unicode now check for the
1681 proper magic slot for type conversions when subclassed. Previously the
1682 magic slot was ignored during conversion. Semantics now match the way
1683 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001684 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001685 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001686 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001687
Barry Warsawc8d907c2005-04-19 23:43:40 +00001688- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1689 NULL, now raise an AttributeError when attempting to set or delete the
1690 attribute. Previously a TypeError was raised, but this was inconsistent
1691 with the equivalent pure-Python implementation.
1692
Michael W. Hudson774479c2005-04-18 08:46:17 +00001693- It is now safe to call PyGILState_Release() before
1694 PyEval_InitThreads() (note that if there is reason to believe there
1695 are multiple threads around you still must call PyEval_InitThreads()
1696 before using the Python API; this fix is for extension modules that
1697 have no way of knowing if Python is multi-threaded yet).
1698
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001699- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1700 disabled caused a crash.
1701
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001702- Bug #1165306: instancemethod_new allowed the creation of a method
1703 with im_class == im_self == NULL, which caused a crash when called.
1704
Tim Petersecc6e6a2005-07-10 22:30:55 +00001705- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001706 fixes the crash seen in bug #1165761
1707
Raymond Hettinger96229b12005-03-11 06:49:40 +00001708- Added two new builtins, any() and all().
1709
Brett Cannon409d8f22005-03-05 06:47:57 +00001710- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001711 (e.g., ``class C(): pass`` is no longer a syntax error).
1712 Patch #1176012 added support to the 'parser' module and 'compiler' package
1713 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001714
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001715- Patch #1115086: Support PY_LONGLONG in structmember.
1716
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001717- Bug #1155938: new style classes did not check that __init__() was
1718 returning None.
1719
Tim Petersecc6e6a2005-07-10 22:30:55 +00001720- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001721 ('\') with a specific error message.
1722
Martin v. Löwisff232d72005-03-03 09:24:38 +00001723- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1724
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001725- Bug #1124295: the __name__ attribute of file objects was
1726 inadvertently made inaccessible in restricted mode.
1727
Tim Petersecc6e6a2005-07-10 22:30:55 +00001728- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001729 an ferror() call.
1730
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001731- min() and max() now support key= arguments with the same meaning as in
1732 list.sort().
1733
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001734- The peephole optimizer now performs simple constant folding in expressions:
1735 (2+3) --> (5).
1736
Raymond Hettingera422c342005-01-11 03:03:27 +00001737- set and frozenset objects can now be marshalled. SF #1098985.
1738
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001739- Bug #1077106: Poor argument checking could cause memory corruption
1740 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001741
Jeremy Hyltonab630502005-02-04 18:44:06 +00001742- The parser did not complain about future statements in illegal
1743 positions. It once again reports a syntax error if a future
1744 statement occurs after anything other than a doc string.
1745
Neil Schemenauercf52c072005-08-12 17:34:58 +00001746- Change the %s format specifier for str objects so that it returns a
1747 unicode instance if the argument is not an instance of basestring and
1748 calling __str__ on the argument returns a unicode instance.
1749
Tim Petersf4e69282006-02-27 17:15:31 +00001750- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1751 current thread state when the auto-GIL-state machinery knows about
1752 it (since the thread state is being deleted, continuing to remember it
1753 can't help, but can hurt if another thread happens to get created with
1754 the same thread id).
1755
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001756Extension Modules
1757-----------------
1758
Georg Brandl43f08a82006-03-31 18:01:16 +00001759- Patch #1380952: fix SSL objects timing out on consecutive read()s
1760
Neal Norwitz05a45592006-03-20 06:30:08 +00001761- Patch #1309579: wait3 and wait4 were added to the posix module.
1762
Anthony Baxterfa869072006-03-20 05:21:58 +00001763- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1764 In addition, the existing ulaw code was updated.
1765
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001766- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00001767 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001768
Neal Norwitz10be10c2006-03-16 06:50:13 +00001769- Everything under lib-old was removed. This includes the following modules:
1770 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00001771 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001772 util, whatsound, whrandom, zmod

Nick Coghlan43832302006-04-23 17:04:07 +00001950- PEP 338: new module runpy defines a run_module function to support
1951 executing modules which provide access to source code or a code object
1952 via the PEP 302 import mechanisms.
1953

1962 in attribute values.
1963
Anthony Baxterc51ee692006-04-01 00:57:31 +00001964- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001965 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001966 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001967 module will not be built.
1968
Tim Petersc17976e2006-04-01 00:26:53 +00001969- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1970 aren't officially supported here, and trying to use them will probably
1971 raise an exception some day. But dicts have been allowed, and "mostly
1972 worked", so support for them won't go away without warning.
1973
Georg Brandl338ef7d2006-03-31 18:42:16 +00001974- Bug #1445068: getpass.getpass() can now be given an explicit stream

1992
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001993- email 4.0 package now integrated. This is largely the same as the email 3.0
1994 package that was included in Python 2.3, except that PEP 8 module names are
1995 now used (e.g. mail.message instead of email.Message). The MIME classes
1996 have been moved to a subpackage (e.g. email.mime.text instead of
1997 email.MIMEText). The old names are still supported for now. Several
1998 deprecated Message methods have been removed and lots of bugs have been
1999 fixed. More details can be found in the email package documentation.
2000
Walter Dörwald40108c92006-03-27 08:15:44 +00002001- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2002 (a subclass of tuple) that provides incremental decoders and encoders
2003 (a way to use stateful codecs without the stream API). Python functions
2004 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2005 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2006 have been added.

2009 a ValueError instead of a StopIteration now (like file and cString.String do).

2081 LoadError as documented, instead of IOError. For compatibility,
2082 LoadError subclasses IOError.
2083
Brett Cannon3cbd0382005-12-16 22:49:23 +00002084- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00002085 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2086 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2087 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2088 Ronald L. Rivest offered this advice for Python:
2089
2090 "The consensus of researchers in this area (at least as
2091 expressed at the NIST Hash Function Workshop 10/31/05),
2092 is that SHA-256 is a good choice for the time being, but
2093 that research should continue, and other alternatives may
2094 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002095
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002096- Added a subset of Fredrik Lundh's ElementTree package. Available

Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002192 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002193 the generate_tokens() function now accepts a callable argument that

2215 work as expected.
2216
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002217- Bug #1163325: Decimal infinities failed to hash. Attempting to

Guido van Rossumd0641422005-02-03 15:01:24 +00002255- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2256 disables recursive traversal through instance attributes, which can
2257 be exploited in various ways.
2258
Tim Peterse3547fd2005-12-16 23:13:57 +00002259- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec

2273
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002274- Enhancements to the csv module:
2275
2276 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002277 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002278 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002279 + Dialect parameter parsing has been re-implemented to improve error
2280 reporting.
2281 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2282 dictates.
2283 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002284 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002285 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002286 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2287 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002288 + reader now allows \r characters to be quoted (previously it only allowed
2289 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002290 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002291 + Dialect classes passed to the module are no longer instantiated by
2292 the module before being parsed (the former validation scheme required
2293 this, but the mechanism was unreliable).
2294 + The dialect registry now contains instances of the internal
2295 C-coded dialect type, rather than references to python objects.
2296 + the internal c-coded dialect type is now immutable.
2297 + register_dialect now accepts the same keyword dialect specifications
2298 as the reader and writer, allowing the user to register dialects
2299 without first creating a dialect class.
2300 + a configurable limit to the size of parsed fields has been added -
2301 previously, an unmatched quote character could result in the entire
2302 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002303 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002304 the parser field size limit (returning the former limit). The initial
2305 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002306 + A line_num attribute has been added to the reader object, which tracks
2307 the number of lines read from the source iterator. This is not
2308 the same as the number of records returned, as records can span
2309 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002310 + reader and writer objects were not being registered with the cyclic-GC.
2311 This has been fixed.
2312
Brett Cannone6539c42005-01-08 02:43:53 +00002313- _DummyThread objects in the threading module now delete self.__block that is
2314 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2315 lock primitives tend to be limited in number and thus should not be wasted on
2316 a _DummyThread object. Fixes bug #1089632.
2317
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002318- The imghdr module now detects Exif files.
2319
Raymond Hettinger6065d322004-12-20 23:51:53 +00002320- StringIO.truncate() now correctly adjusts the size attribute.
2321 (Bug #951915).
2322
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002323- locale.py now uses an updated locale alias table (built using
2324 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2325 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002326 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002327
Raymond Hettinger3557f422004-12-07 12:02:02 +00002328- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2329
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002330- the pickle module no longer accepts the deprecated None option in the
2331 args tuple returned by __reduce__().
2332
Brett Cannon84667c02004-12-07 03:25:18 +00002333- optparse now optionally imports gettext. This allows its use in setup.py.
2334
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002335- the pickle module no longer uses the deprecated bin parameter.
2336
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002337- the shelve module no longer uses the deprecated binary parameter.
2338
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002339- the pstats module no longer uses the deprecated ignore() method.
2340
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002341- the filecmp module no longer uses the deprecated use_statcache argument.
2342
Raymond Hettinger664347b2004-12-04 21:21:53 +00002343- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2344 extended or overridden by subclasses. Formerly, the subclassed method would
2345 be ignored by the rest of the module. (Bug #1078905).
2346
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002347- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002348 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002349
Walter Dörwald36733692004-12-22 12:50:50 +00002350- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2351 once when a size argument is given. This prevents a buffer overflow in the
2352 tokenizer with very long source lines.
2353
Barry Warsaw538561e2006-01-01 21:48:54 +00002354- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2355 immediately after creating the object, without any intervening
2356 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002357
Skip Montanaro05885812005-01-16 20:48:27 +00002358- The reconvert.quote function can now emit triple-quoted strings. The
2359 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002360
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002361- ``UserString.MutableString`` now supports negative indices in
2362 ``__setitem__`` and ``__delitem__``
2363
Greg Ward40407942005-03-05 02:53:17 +00002364- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2365 correctly.
2366
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002367- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2368 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2369 character even if the user has passed a size parameter to get a proper
2370 line ending. Remove the special handling of a "\r\n" that has been split
2371 between two lines.
2372
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002373- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2374 about illegal code points. The codec now supports PEP 293 style error
2375 handlers.
2376
Walter Dörwald78a78b02005-09-01 12:04:29 +00002377- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002378 from the input stream, so that the output is a byte string in the correct
2379 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002380
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002381- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2382 considering it exactly like a '*'.
2383
Walter Dörwald007f8df2005-10-09 19:42:27 +00002384- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2385 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002386
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002387- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2388
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002389- Patch #1413711: Certain patterns of differences were making difflib
2390 touch the recursion limit.
2391
Walter Dörwald58917a62006-03-31 15:26:22 +00002392- Bug #947906: An object oriented interface has been added to the calendar
2393 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002394 called as a script (e.g. via ``python -mcalendar``). Localized month and
2395 weekday names can be ouput (even if an exotic encoding is used) using
2396 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002397
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002398Build
2399-----
2400
Neal Norwitz602d3392006-03-31 08:21:40 +00002401- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2402 by using -mieee gcc option.
2403
Martin v. Löwis86d66262006-02-17 08:40:11 +00002404- Patch #1432345: Make python compile on DragonFly.
2405
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002406- Build support for Win64-AMD64 was added.
2407
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002408- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2409
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002410- Patch #881820: look for openpty and forkpty also in libbsd.
2411
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002412- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2413 The zlib module is now builtin on Windows.
2414
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002415- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2416
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002417- Bug #1189330: configure did not correctly determine the necessary
2418 value of LINKCC if python was built with GCC 4.0.
2419
Trent Mick8321b422005-07-26 02:29:21 +00002420- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2421 vulnerability in zlib 1.2.1 and 1.2.2.
2422
Brett Cannon08cd5982005-04-24 22:26:38 +00002423- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2424 flags that change binary compatibility. Changes were also made to
2425 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002426 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002427
Bob Ippolitoed233462005-03-29 13:47:59 +00002428- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2429 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2430 no longer exists). This configure patch makes things right.
2431
Martin v. Löwise2713be2005-03-08 15:03:08 +00002432- Bug #1158607: Build with --disable-unicode again.
2433
Brett Cannon46d96232005-02-16 00:07:19 +00002434- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2435 defined. Discovered as a result of not being able to build on OS X.
2436
Brett Cannon516592f2004-12-07 00:42:59 +00002437- setup.py now uses the directories specified in LDFLAGS using the -L option
2438 and in CPPFLAGS using the -I option for adding library and include
2439 directories, respectively, for compiling extension modules against. This has
2440 led to the core being compiled using the values in CPPFLAGS. It also removes
2441 the need for the special-casing of both DarwinPorts and Fink for darwin since
2442 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2443 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2444 Fink, ``-I/opt/local/include`` for DarwinPorts).
2445
Brett Cannon43802422005-02-10 20:48:03 +00002446- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2447 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2448 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2449 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002451C API
2452-----
2453
Tim Petersc9d78aa2006-03-26 23:27:58 +00002454- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2455 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2456 is obtained via the ``PyObject_`` family, it must be released via the
2457 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2458 always been officially true, but when Python's small-object allocator was
2459 introduced, an attempt was made to cater to a few extension modules
2460 discovered at the time that obtained memory via ``PyObject_New`` but
2461 released it via ``PyMem_DEL``. It's years later, and if such code still
2462 exists it will fail now (probably with segfaults, but calling wrong
2463 low-level memory management functions can yield many symptoms).
2464
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002465- Added a C API for set and frozenset objects.
2466
Raymond Hettinger66517482004-12-03 11:45:13 +00002467- Removed PyRange_New().
2468
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002469- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2470 mapping argument now. This string is used as a mapping table. Byte values
2471 greater than the length of the string and 0xFFFE are treated as undefined
2472 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002479
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002480- Patch #1276356: New resource "urlfetch" is implemented. This enables
2481 even impatient people to run tests that require remote files.

2532 vimrc to it (was previous up a level).
2533
Georg Brandl56897312005-08-24 18:32:30 +00002534- Added two new files to Tools/scripts: pysource.py, which recursively
