395Core and builtins
396-----------------
397
Neal Norwitz24b6f202006-09-05 04:43:56 +0000398- Fix infinite recursion when subclassing long and overriding __hash__.
399
400- Fix concatenation (+=) of long strings.
401
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000402- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000403 compared equal or unequal to a string and a UnicodeDecodeError
404 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000405
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000406 Instead, the equal (==) and unequal (!=) comparison operators will
407 now issue a UnicodeWarning and interpret the two objects as
408 unequal. The UnicodeWarning can be filtered as desired using
409 the warning framework, e.g. silenced completely, turned into an
410 exception, logged, etc.
411
412 Note that compare operators other than equal and unequal will still
413 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000414
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000415- Fix segfault when doing string formatting on subclasses of long.
416
417- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
418 with new-style classes.
419
420- Fix bug related to __len__ functions returning negative values with
421 classic classes.
422
423- Patch #1538606, Fix __index__() clipping. There were some problems
424 discovered with the API and how integers that didn't fit into Py_ssize_t
425 were handled. This patch attempts to provide enough alternatives
426 to effectively use __index__.
427
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000428- Bug #1536021: __hash__ may now return long int; the final hash
429 value is obtained by invoking hash on the long int.
430
Thomas Hellerab1049c2006-08-08 17:37:00 +0000431- Bug #1536786: buffer comparison could emit a RuntimeWarning.
432
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000433- Bug #1535165: fixed a segfault in input() and raw_input() when
434 sys.stdin is closed.
435
Thomas Heller74d36f02006-08-04 18:17:40 +0000436- On Windows, the PyErr_Warn function is now exported from
437 the Python dll again.
438
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000439- Bug #1191458: tracing over for loops now produces a line event
440 on each iteration. Fixing this problem required changing the .pyc
441 magic number. This means that .pyc files generated before 2.5c1
442 will be regenerated.
443
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000444- Bug #1333982: string/number constants were inappropriately stored
445 in the byte code and co_consts even if they were not used, ie
446 immediately popped off the stack.
447
Georg Brandle9462c72006-08-04 18:03:37 +0000448- Fixed a reference-counting problem in property().

451Library
452-------
453
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000454- Fix a bug in the ``compiler`` package that caused invalid code to be
455 generated for generator expressions.
456
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000457- The distutils version has been changed to 2.5.0. The change to
458 keep it programmatically in sync with the Python version running
459 the code (introduced in 2.5b3) has been reverted. It will continue
460 to be maintained manually as static string literal.
461
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000462- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000463 and this cannot be converted to the required C type, an exception is
464 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000465 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000466
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000467- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000468 an exception.
469
Tim Peterscbdd3502006-09-05 01:47:53 +0000470- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000471 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000472 workarounds for clocks with low resolution, to stop the code yielding
473 duplicate UUIDs.
474
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000475- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
476 before raising SystemExit, allowing IDLE to honor quit() and exit().
477
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000478- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
479
Georg Brandl7a1af772006-08-14 21:55:28 +0000480- Patch #1536071: trace.py should now find the full module name of a
481 file correctly even on Windows.
482
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000483- logging's atexit hook now runs even if the rest of the module has
484 already been cleaned up.
485
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000486- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000487
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000488- Bug #1531405, format_exception no longer raises an exception if
489 str(exception) raised an exception.
490
Neil Schemenauer06ded092006-08-04 16:20:30 +0000491- Fix a bug in the ``compiler`` package that caused invalid code to be
492 generated for nested functions.

503 raises the correct exceptions.
504
Thomas Heller1ce433e2006-08-14 16:20:04 +0000505- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
506 '-no-stack-protector' compiler flag for OpenBSD has been removed.
507
Thomas Heller86720042006-08-14 11:17:48 +0000508- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
509 uses the _as_parameter_ attribute when objects are passed to foreign
510 function calls. The ctypes version number was changed to 1.0.1.
511
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000512- Bug #1530559, struct.pack raises TypeError where it used to convert.
513 Passing float arguments to struct.pack when integers are expected
514 now triggers a DeprecationWarning.

564Core and builtins
565-----------------
566
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000567- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000568 returned a long (see PEP 353).
569
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000570- Bug #1515471: string.replace() accepts character buffers again.
571
Neal Norwitz07aadb12006-07-30 06:55:48 +0000572- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
573 This provides the proper warning for struct.pack().
574 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
575
Neal Norwitz0d62a062006-07-30 06:53:31 +0000576- Patch #1531113: Fix augmented assignment with yield expressions.
577 Also fix a SystemError when trying to assign to yield expressions.
578
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000579- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
580 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
581 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
582 excessive filesystem operations during imports.
583
Tim Petersbc24eee2006-07-27 01:14:53 +0000584- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
585 operations on signed longs that are formally undefined by C.
586 Unfortunately, at least one compiler now cares about that, so complicated
587 the code to make that compiler happy again.
588
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000589- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
590
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000591- Patch #1232023: Stop including current directory in search
592 path on Windows.
593
Neal Norwitze1fdb322006-07-21 05:32:28 +0000594- Fix some potential crashes found with failmalloc.
595
Neal Norwitze7563102006-07-17 01:00:16 +0000596- Fix warnings reported by Klocwork's static analysis tool.
597
Neal Norwitz84be93b2006-07-16 01:50:38 +0000598- Bug #1512814, Fix incorrect lineno's when code within a function
599 had more than 255 blank lines.
600
Georg Brandl9dceedb2006-07-12 15:31:17 +0000601- Patch #1521179: Python now accepts the standard options ``--help`` and
602 ``--version`` as well as ``/?`` on Windows.
603
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000604- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000605 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000606 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000607
Tim Peters112aad32006-07-19 00:03:19 +0000608- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000609 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000610 new ``sys._current_frames()`` returns a dictionary with one entry,
611 mapping the faux "thread id" 0 to the current frame.
612

617-------
618
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000619- Correction of patch #1455898: In the mbcs decoder, set final=False
620 for stream decoder, but final=True for the decode function.
621
Georg Brandl07fec3a2006-08-01 18:49:24 +0000622- os.urandom no longer masks unrelated exceptions like SystemExit or
623 KeyboardInterrupt.
624
Tim Peters4643c2f2006-08-10 22:45:34 +0000625- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000626 shutil.copytree on Windows
627
Georg Brandle34ac7c2006-07-30 11:07:23 +0000628- Bug #1002398: The documentation for os.path.sameopenfile now correctly
629 refers to file descriptors, not file objects.
630
Tim Peterscbdd3502006-09-05 01:47:53 +0000631- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000632 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000633 #1513611, and probably others.
634
Georg Brandledd9b0d2006-07-29 09:33:26 +0000635- Bug #1441397: The compiler module now recognizes module and function
636 docstrings correctly as it did in Python 2.4.
637
Tim Peters6f681472006-07-27 23:44:37 +0000638- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
639 lost that tests are sorted by name before being run. This rarely
640 matters for well-written tests, but can create baffling symptoms if
641 side effects from one test to the next affect outcomes. ``DocTestFinder``
642 has been changed to sort the list of tests it returns.
643
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000644- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000645 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000646
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000647- Bug #978833: Really close underlying socket in _socketobject.close.
648
Georg Brandldb232dc2006-08-20 13:15:43 +0000649- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
650 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000651
Georg Brandlcf0c1722006-07-26 07:23:32 +0000652- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
653 to recursive calls and call it with the failing package name.
654
Martin v. Löwis0b483032006-07-25 09:53:12 +0000655- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
656
Georg Brandlc13c34c2006-07-24 14:09:56 +0000657- Patch #1515343: Fix printing of deprecated string exceptions with a
658 value in the traceback module.
659
Greg Ward48fae7a2006-07-23 16:05:51 +0000660- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
661
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000662- Patch #1524429: Use repr() instead of backticks in Tkinter again.
663
Brett Cannoncaebe222006-07-18 04:41:36 +0000664- Bug #1520914: Change time.strftime() to accept a zero for any position in its
665 argument tuple. For arguments where zero is illegal, the value is forced to
666 the minimum value that is correct. This is to support an undocumented but
667 common way people used to fill in inconsequential information in the time
668 tuple pre-2.4.
669
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000670- Patch #1220874: Update the binhex module for Mach-O.
671
Barry Warsawb110bad2006-07-21 14:51:07 +0000672- The email package has improved RFC 2231 support, specifically for
673 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
674 (name*0=<blah>) parameter continuations. This may change the types of
675 values returned from email.message.Message.get_param() and friends.
676 Specifically in some cases where non-encoded continuations were used,
677 get_param() used to return a 3-tuple of (None, None, string) whereas now it
678 will just return the string (since non-encoded continuations don't have
679 charset and language parts).
680
681 Also, whereas % values were decoded in all parameter continuations, they are
682 now only decoded in encoded parameter parts.
683
Ronald Oussoren3075e162006-07-25 20:28:55 +0000684- Bug #1517990: IDLE keybindings on MacOS X now work correctly
685
686- Bug #1517996: IDLE now longer shows the default Tk menu when a
687 path browser, class browser or debugger is the frontmost window on MacOS X
688
Barry Warsaw00decd72006-07-27 23:43:15 +0000689- Patch #1520294: Support for getset and member descriptors in types.py,
690 inspect.py, and pydoc.py. Specifically, this allows for querying the type
691 of an object against these built-in types and more importantly, for getting
692 their docstrings printed in the interactive interpreter's help() function.

696-----------------
697
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000698- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
699 a socket operation on a socket with a timeout, the exception will be
700 caught correctly. Previously, the exception was not caught.
701
Thomas Heller1393d6a2006-07-28 21:43:20 +0000702- Patch #1529514: The _ctypes extension is now compiled on more
703 openbsd target platforms.
704
Tim Peters9cab5932006-07-28 00:30:00 +0000705- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
706 a memory leak, affecting pickles and deep copies.
707
Tim Petersbc24eee2006-07-27 01:14:53 +0000708- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

710
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000711- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
712
Thomas Hellerce049a02006-07-14 17:51:14 +0000713- Patch #1521817: Index range checking on ctypes arrays containing
714 exactly one element enabled again. This allows iterating over these
715 arrays, without the need to check the array size before.
716
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000717- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000718 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000719 /dev/null in certain cases; this is now fixed.
720
Thomas Heller47d7a062006-07-12 08:43:47 +0000721- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
722 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000723
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000724- Because of a misspelled preprocessor symbol, ctypes was always
725 compiled without thread support; this is now fixed.
726
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000727- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
728 methods now allow their database parameter to be None as the
729 sleepycat API allows.
730
Matt Flemingec926502006-07-28 11:27:27 +0000731- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
732 bluetooth API compared with Linux and FreeBSD.
733
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000734Tests
735-----
736
737- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
738 how long the test file should take to play. Now accepts taking 2.93 secs
739 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
740
Georg Brandl4793aa32006-07-28 18:31:39 +0000741- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
742 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
743 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +0000750Mac
751---
752
753- PythonLauncher now works correctly when the path to the script contains
754 characters that are treated specially by the shell (such as quotes).
755
756- Bug #1527397: PythonLauncher now launches scripts with the working directory
757 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000758 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000759 expect.

767Core and builtins
768-----------------
769
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000770- Bug #1441486: The literal representation of -(sys.maxint - 1)
771 again evaluates to a int object, not a long.
772
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000773- Bug #1501934: The scope of global variables that are locally assigned
774 using augmented assignment is now correctly determined.
775
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000776- Bug #927248: Recursive method-wrapper objects can now safely
777 be released.
778
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000779- Bug #1417699: Reject locale-specific decimal point in float()
780 and atof().
781
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000782- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
783 omit a default "error" argument for NULL pointer. This allows
784 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000785
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000786- Bug #1519018: 'as' is now validated properly in import statements.
787
Neal Norwitz28746ab2006-07-09 22:14:42 +0000788- On 64 bit systems, int literals that use less than 64 bits are
789 now ints rather than longs.
790
Neal Norwitzed657552006-07-10 00:04:44 +0000791- Bug #1512814, Fix incorrect lineno's when code at module scope
792 started after line 256.
793
Tim Peters32a83612006-07-10 21:08:24 +0000794- New function ``sys._current_frames()`` returns a dict mapping thread
795 id to topmost thread stack frame. This is for expert use, and is
796 especially useful for debugging application deadlocks. The functionality
797 was previously available in Fazal Majid's ``threadframe`` extension
798 module, but it wasn't possible to do this in a wholly threadsafe way from
799 an extension.

816
Thomas Woutersadd19112006-07-05 11:03:49 +0000817- string.Template() now correctly handles tuple-values. Previously,
818 multi-value tuples would raise an exception and single-value tuples would
819 be treated as the value they contain, instead.

Georg Brandl1be63af2006-06-28 20:23:25 +0000845- Fix a bug in the turtle module's end_fill function.
846
Brett Cannon53ab5b72006-06-22 16:49:14 +0000847- Bug #1510580: The 'warnings' module improperly required that a Warning
848 category be either a types.ClassType and a subclass of Warning. The proper
849 check is just that it is a subclass with Warning as the documentation states.
850
Georg Brandlad29e632006-06-21 17:45:17 +0000851- The compiler module now correctly compiles the new try-except-finally
852 statement (bug #1509132).
853
Neal Norwitz60373cd2006-06-22 06:30:50 +0000854- The wsgiref package is now installed properly on Unix.
855
Vinay Sajip28e57612006-07-01 10:45:20 +0000856- A bug was fixed in logging.config.fileConfig() which caused a crash on
857 shutdown when fileConfig() was called multiple times.
858
Gerhard Häring762fbd32006-07-02 17:48:30 +0000859- The sqlite3 module did cut off data from the SQLite database at the first
860 null character before sending it to a custom converter. This has been fixed
861 now.

Tim Peters112aad32006-07-19 00:03:19 +0000866- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
867 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
868 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000869
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000870- Assigning None to pointer type fields in ctypes structures possible
871 overwrote the wrong fields, this is fixed now.
872
873- Fixed a segfault in _ctypes when ctypes.wintypes were imported
874 on non-Windows platforms.
875
876- Bug #1518190: The ctypes.c_void_p constructor now accepts any
877 integer or long, without range checking.
878
879- Patch #1517790: It is now possible to use custom objects in the ctypes
880 foreign function argtypes sequence as long as they provide a from_param
881 method, no longer is it required that the object is a ctypes type.
882
883- The '_ctypes' extension module now works when Python is configured
884 with the --without-threads option.
885
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000886- Bug #1513646: os.access on Windows now correctly determines write

901
Tim Peters32a83612006-07-10 21:08:24 +0000902- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000903 Previously, the slight difference could cause compilation errors of the
904 'zlib' module on systems with more than one version of zlib.
905
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000906- The MSI compileall step was fixed to also support a TARGETDIR

Anthony Baxter51bcb682006-04-05 14:51:42 +0000936
937Core and builtins
938-----------------
939
Georg Brandla56b9152006-06-19 06:35:54 +0000940- Patch #1507676: Error messages returned by invalid abstract object operations
941 (such as iterating over an integer) have been improved and now include the
942 type of the offending object to help with debugging.
943
Brett Cannonea3912b2006-06-13 21:46:41 +0000944- Bug #992017: A classic class that defined a __coerce__() method that returned
945 its arguments swapped would infinitely recurse and segfault the interpreter.
946
Neal Norwitz909eb122006-06-12 02:13:21 +0000947- Fix the socket tests so they can be run concurrently.
948
Neal Norwitzb9845e72006-06-12 02:11:18 +0000949- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000950 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000951
Brett Cannon22565aa2006-06-09 22:31:23 +0000952- Bug #532646: object.__call__() will continue looking for the __call__
953 attribute on objects until one without one is found. This leads to recursion
954 when you take a class and set its __call__ attribute to an instance of the
955 class. Originally fixed for classic classes, but this fix is for new-style.
956 Removes the infinite_rec_3 crasher.
957
Georg Brandl24250812006-06-09 18:45:48 +0000958- The string and unicode methods startswith() and endswith() now accept
959 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
960
Brett Cannonde3b0522006-06-08 17:00:45 +0000961- Buffer objects, at the C level, never used the char buffer
962 implementation even when the char buffer for the wrapped object was
963 explicitly requested (originally returned the read or write buffer).
964 Now a TypeError is raised if the char buffer is not present but is
965 requested.
966
Georg Brandlddbaa662006-06-04 21:56:52 +0000967- Patch #1346214: Statements like "if 0: suite" are now again optimized
968 away like they were in Python 2.4.
969
Georg Brandlb7c8f542006-05-27 12:30:25 +0000970- Builtin exceptions are now full-blown new-style classes instead of
971 instances pretending to be classes, which speeds up exception handling
972 by about 80% in comparison to 2.5a2.
973
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000974- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
975 Unicode 4.1.
976
Georg Brandlf4ef1162006-05-26 18:03:31 +0000977- Patch #921466: sys.path_importer_cache is now used to cache valid and
978 invalid file paths for the built-in import machinery which leads to
979 fewer open calls on startup.
980
Tim Peters696cf432006-05-24 21:10:40 +0000981- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
982 of-2 bases. The largest speedup is for inputs with about 1000 decimal
983 digits. Conversion from non-power-of-2 bases remains quadratic-time in
984 the number of input digits (it was and remains linear-time for bases
985 2, 4, 8, 16 and 32).
986
Tim Petersb713ec22006-05-23 18:45:30 +0000987- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
988 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
989 an integer close to ``sys.maxint``. This was repaired by patch
990 #1335972, which also gives a nice speedup.
991
Richard Jonescebbefc2006-05-23 18:28:17 +0000992- Patch #1337051: reduced size of frame objects.
993
994- PyErr_NewException now accepts a tuple of base classes as its
995 "base" parameter.
996
Richard Jones7c88dcc2006-05-23 10:37:38 +0000997- Patch #876206: function call speedup by retaining allocated frame
998 objects.
999
Georg Brandl7b90e162006-05-18 07:01:27 +00001000- Bug #1462152: file() now checks more thoroughly for invalid mode
1001 strings and removes a possible "U" before passing the mode to the
1002 C library function.
1003
Neal Norwitz1004a532006-05-15 07:17:23 +00001004- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1005
Neal Norwitz373f0a72006-05-15 07:04:36 +00001006- Bug #1487966: Fix SystemError with conditional expression in assignment
1007
Martin v. Löwis879768d2006-05-11 13:28:43 +00001008- WindowsError now has two error code attributes: errno, which carries
1009 the error values from errno.h, and winerror, which carries the error
1010 values from winerror.h. Previous versions put the winerror.h values
1011 (from GetLastError()) into the errno attribute.
1012
Martin v. Löwis77736712006-05-04 05:51:03 +00001013- Patch #1475845: Raise IndentationError for unexpected indent.
1014
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001015- Patch #1479181: split open() and file() from being aliases for each other.
1016
Tim Peters44bd9862006-06-01 13:49:23 +00001017- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1018 methods were always silently ignored by dictionaries when comparing keys.
1019 They are now passed through (except when using the C API function
1020 ``PyDict_GetItem()``, whose semantics did not change).
1021
1022- Bug #1456209: In some obscure cases it was possible for a class with a
1023 custom ``__eq__()`` method to confuse dict internals when class instances
1024 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1025 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001027Extension Modules
1028-----------------
1029
Trent Mick960a3f82006-06-28 20:30:41 +00001030- Bug #1295808: expat symbols should be namespaced in pyexpat
1031
1032- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1033
Brett Cannon6ee7d012006-06-08 16:23:04 +00001034- Change binascii.hexlify to accept a read-only buffer instead of only a char
1035 buffer and actually follow its documentation.
1036
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001037- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1038
Nick Coghlanc649ec52006-05-29 12:43:05 +00001039- Patch #1478788 (modified version): The functional extension module has
1040 been renamed to _functools and a functools Python wrapper module added.
1041 This provides a home for additional function related utilities that are
1042 not specifically about functional programming. See PEP 309.
1043
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001044- Patch #1493701: performance enhancements for struct module.
1045
Georg Brandl378d5922006-05-17 14:26:50 +00001046- Patch #1490224: time.altzone is now set correctly on Cygwin.
1047
Georg Brandl8d3342b2006-05-16 07:38:27 +00001048- Patch #1435422: zlib's compress and decompress objects now have a
1049 copy() method.
1050
Andrew MacIntyre92913322006-06-13 15:04:24 +00001051- Patch #1454481: thread stack size is now tunable at runtime for thread
1052 enabled builds on Windows and systems with Posix threads support.
1053
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001054- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1055 (up to the system limit of 32K characters).
1056
1057- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1058 As a result, these functions now raise WindowsError instead of OSError.
1059
Tim Peters7a822da2006-05-25 21:50:17 +00001060- ``time.clock()`` on Win64 should use the high-performance Windows
1061 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1062 Windows platforms).
1063
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001064- Calling Tk_Init twice is refused if the first call failed as that
1065 may deadlock.
1066
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001067- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1068 accept it without potentially using an uninitialized pointer.
1069
1070- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1071 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1072 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001073
Gregory P. Smith372b5832006-06-05 18:48:21 +00001074- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001075 [pybsddb project SF patch number 1466734]
1076
Gregory P. Smith372b5832006-06-05 18:48:21 +00001077- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1078 parameter is supplied. [SF pybsddb bug #1477863]
1079
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001080- bsddb: the __len__ method of a DB object has been fixed to return correct
1081 results. It could previously incorrectly return 0 in some cases.
1082 Fixes SF bug 1493322 (pybsddb bug 1184012).
1083
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001084- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1085 aborts the db transaction safely when a modifier callback fails.
1086 Fixes SF python patch/bug #1408584.
1087
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001088- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001089 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001090 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1091 database calls that would previously deadlock. [SF python bug #775414]
1092
Vinay Sajip28e57612006-07-01 10:45:20 +00001093- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001094
Walter Dörwald4994d952006-06-19 08:07:50 +00001095- Patch #1506645: add Python wrappers for the curses functions
1096 is_term_resized, resize_term and resizeterm.

1100
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001101- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1102 functions.
1103
Martin v. Löwis3798da02006-06-17 18:44:27 +00001104- Patch #812986: Update turtle output even if not tracing.
1105
Vinay Sajip28e57612006-07-01 10:45:20 +00001106- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001107 Tkinter.BaseWidget.
1108
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001109- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1110
Martin v. Löwis337487e2006-06-17 09:15:14 +00001111- Patch #763580: Add name and value arguments to Tkinter variable
1112 classes.
1113
Georg Brandl83cc0d02006-06-14 08:50:03 +00001114- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1115 mime.types file for determining MIME types.
1116
Georg Brandl2605ca82006-06-14 06:08:31 +00001117- Bug #1339007: Shelf objects now don't raise an exception in their
1118 __del__ method when initialization failed.
1119
Martin v. Löwisd8251432006-06-14 05:21:04 +00001120- Patch #1455898: The MBCS codec now supports the incremental mode for
1121 double-byte encodings.
1122
Tim Peters43898b42006-06-14 04:09:25 +00001123- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1124 guarantee that adjacent triples in the return list always describe
1125 non-adjacent blocks. Previously, a pair of matching blocks could end
1126 up being described by multiple adjacent triples that formed a partition
1127 of the matching pair.
1128
Greg Ward0e0c9f42006-06-11 16:24:11 +00001129- Bug #1498146: fix optparse to handle Unicode strings in option help,
1130 description, and epilog.
1131
Greg Wardd1c797e2006-06-11 14:42:41 +00001132- Bug #1366250: minor optparse documentation error.
1133
Greg Ward7f547402006-06-11 00:40:49 +00001134- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1135 clarify docs.
1136
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001137- The wsgiref package has been added to the standard library.
1138
Nick Coghlan676725d2006-06-08 13:54:49 +00001139- The functions update_wrapper() and wraps() have been added to the functools
1140 module. These make it easier to copy relevant metadata from the original
1141 function when writing wrapper functions.
1142
Tim Petersd6a9eef2006-06-05 01:48:21 +00001143- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1144 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001145
Martin v. Löwis3f767792006-06-04 19:36:28 +00001146- Patch #1359618: Speed up charmap encoder by using a trie structure
1147 for lookup.
1148
Tim Petersd609b1a2006-06-02 23:22:51 +00001149- The functions in the ``pprint`` module now sort dictionaries by key
1150 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1151 if and only if its display required more than one line, although that
1152 wasn't documented. The new behavior increases predictability; e.g.,
1153 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1154
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001155- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1156 (thanks for J. J. Lee).
1157
Georg Brandl2b330372006-05-28 20:23:12 +00001158- Patch #1496206: improve urllib2 handling of passwords with respect to
1159 default HTTP and HTTPS ports.
1160
George Yoshidaf3c65de2006-05-28 16:39:09 +00001161- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1162
Bob Ippolito7298f272006-05-23 18:43:47 +00001163- Patch #1281707: speed up gzip.readline.
1164
Georg Brandlb89316f2006-05-17 15:51:16 +00001165- Patch #1180296: Two new functions were added to the locale module:
1166 format_string() to get the effect of "format % items" but locale-aware,
1167 and currency() to format a monetary number with currency sign.
1168
Georg Brandle3a25832006-05-17 14:56:04 +00001169- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1170 and several features added, such as speed and geometry control.
1171
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001172- Patch #1488881: add support for external file objects in bz2 compressed
1173 tarfiles.
1174
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001175- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1176 stdout arguments, making it possible to redirect input and output
1177 for remote debugging.
1178
1179- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1180 a couple of issues, notably handling of long file names using the
1181 GNU LONGNAME extension.
1182
1183- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1184 new flag when ``name`` is already the name of an option flag.
1185
1186- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1187 package.
1188
1189- Patch #1472854: make the rlcompleter.Completer class usable on non-
1190 UNIX platforms.
1191
1192- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1193
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001194- Bug #1472827: correctly escape newlines and tabs in attribute values in
1195 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001225What's New in Python 2.5 alpha 2?
1226=================================
1227
1228*Release date: 27-APR-2006*
1229
1230Core and builtins
1231-----------------
1232
Thomas Heller1b046642006-04-18 18:51:06 +00001233- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1234 by converting these apis from macros into exported functions again:
1235
1236 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1237 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1238 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1239 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1240 PyRun_String Py_CompileString
1241
Martin v. Löwis45294a92006-04-18 06:24:08 +00001242- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1243
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001244- All uses of PyStructSequence_InitType have been changed to initialize
1245 the type objects only once, even if the interpreter is initialized
1246 multiple times.
1247
Neal Norwitz61546162006-04-14 05:20:28 +00001248- Bug #1454485, array.array('u') could crash the interpreter. This was
1249 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1250 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1251
1252- Py_UNICODE is unsigned. It was always documented as unsigned, but
1253 due to a bug had a signed value in previous versions.
1254
Tim Peters3a5e8b12006-04-11 01:44:07 +00001255- Patch #837242: ``id()`` of any Python object always gives a positive
1256 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1257 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001258 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001259 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001260
Tim Peters3a5e8b12006-04-11 01:44:07 +00001261 def __hash__(self):
1262 return id(self) # WRONG
1263
1264 because a hash result must be a (short) Python int but it was always
1265 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001266 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001267 was always usable as a hash value before this patch. That's no longer
1268 necessarily so.
1269
1270- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001271 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001272 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001273 #1454844)
1274
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001275- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1276 involving generators that have paused outside of any ``try`` or ``with``
1277 blocks. (In 2.5a1, a paused generator that was part of a reference
1278 cycle could not be garbage collected, regardless of whether it was
1279 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001280
Anthony Baxter51bcb682006-04-05 14:51:42 +00001281Extension Modules
1282-----------------
1283
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001284- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1285 is a macro.
1286
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001287- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1288 fails with an error condition.
1289
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001290- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1291
1292- Bug #1117761: bsddb.*open() no longer raises an exception when using
1293 the cachesize parameter.
1294
1295- Bug #1149413: bsddb.*open() no longer raises an exception when using
1296 a temporary db (file=None) with the 'n' flag to truncate on open.
1297
1298- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1299 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001300
Armin Rigoa9017c32006-04-19 11:50:27 +00001301- Patch #1062014: AF_UNIX sockets under Linux have a special
1302 abstract namespace that is now fully supported.
1303
Anthony Baxter51bcb682006-04-05 14:51:42 +00001304Library
1305-------
1306
Peter Astrand7d1d4362006-07-14 14:04:45 +00001307- Bug #1223937: subprocess.CalledProcessError reports the exit status
1308 of the process using the returncode attribute, instead of
1309 abusing errno.
1310
Tim Peters711bf302006-04-25 03:31:36 +00001311- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1312 a doctest to be skipped (the code is not run, and the expected output
1313 or exception is ignored).
1314
Nick Coghlanda2268f2006-04-24 04:37:15 +00001315- Fixed contextlib.nested to cope with exceptions being raised and
1316 caught inside exit handlers.
1317
Greg Wardab05edc2006-04-23 03:47:58 +00001318- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1319 hex, octal, or binary; add ``append_const`` action; keep going if
1320 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1321 added ``epilog`` for better help generation).
1322
Tim Peters21fbd572006-04-21 21:18:10 +00001323- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1324 called from a thread spawned as a side effect of importing a module.
1325
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001326- The pydoc module now supports documenting packages contained in
1327 .zip or .egg files.
1328
1329- The pkgutil module now has several new utility functions, such
1330 as ``walk_packages()`` to support working with packages that are either
1331 in the filesystem or zip files.
1332
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001333- The mailbox module can now modify and delete messages from
1334 mailboxes, in addition to simply reading them. Thanks to Gregory
1335 K. Johnson for writing the code, and to the 2005 Google Summer of
1336 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001337
Tim Petersc7605f22006-04-17 21:12:33 +00001338- The ``__del__`` method of class ``local`` in module ``_threading_local``
1339 returned before accomplishing any of its intended cleanup.
1340
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001341- Patch #790710: Add breakpoint command lists in pdb.
1342
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001343- Patch #1063914: Add Tkinter.Misc.clipboard_get().
1344
Martin v. Löwis4b501e62006-04-15 08:41:11 +00001345- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1346
Anthony Baxtere29002c2006-04-12 12:07:31 +00001347- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1348 Windows. Bug #1469163.
1349
Phillip J. Eby47032112006-04-11 01:07:43 +00001350- The warnings, linecache, inspect, traceback, site, and doctest modules
1351 were updated to work correctly with modules imported from zipfiles or
1352 via other PEP 302 __loader__ objects.
1353
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001354- Patch #1467770: Reduce usage of subprocess._active to processes which
1355 the application hasn't waited on.
1356
Martin v. Löwisb04dee92006-04-10 08:34:21 +00001357- Patch #1462222: Fix Tix.Grid.
1358
Neal Norwitza31bf182006-04-09 03:35:43 +00001359- Fix exception when doing glob.glob('anything*/')
1360
Skip Montanaro262fb922006-04-21 02:31:07 +00001361- The pstats.Stats class accepts an optional stream keyword argument to
1362 direct output to an alternate file-like object.
1363
Anthony Baxter51bcb682006-04-05 14:51:42 +00001364Build
1365-----
1366
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001367- The Makefile now has a reindent target, which runs reindent.py on
1368 the library.
1369
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001370- Patch #1470875: Building Python with MS Free Compiler
1371
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001372- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001373
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001374- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1375 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001376 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001377 CXX from --with-cxx-main, see description in README.
1378
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001379- Patch #1429775: Link extension modules with the shared libpython.
1380
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001381- Fixed a libffi build problem on MIPS systems.
1382
Tim Peters8931ff12006-05-13 23:28:20 +00001383- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1384 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1385 and "%zu" for unsigned integers of type ``size_t``.
1386
Anthony Baxter51bcb682006-04-05 14:51:42 +00001387Tests
1388-----
1389
Nick Coghlanda2268f2006-04-24 04:37:15 +00001390- test_contextlib now checks contextlib.nested can cope with exceptions
1391 being raised and caught inside exit handlers.
1392
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001393- test_cmd_line now checks operation of the -m and -c command switches
1394
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001395- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1396 it separately and by hand. It also wasn't cleaning up its changes to
1397 the current Decimal context.
1398
Thomas Woutersabd08882006-04-26 15:53:30 +00001399- regrtest.py now has a -M option to run tests that test the new limits of
1400 containers, on 64-bit architectures. Running these tests is only sensible
1401 on 64-bit machines with more than two gigabytes of memory. The argument
1402 passed is the maximum amount of memory for the tests to use.
1403
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001404Tools

1406
1407- Added the Python benchmark suite pybench to the Tools/ directory;
1408 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001410Documentation
1411-------------
1412
Tim Petersb06d28c2006-05-12 01:57:59 +00001413- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1414
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001415- PEP 343: Added Context Types section to the library reference
1416 and attempted to bring other PEP 343 related documentation into
1417 line with the implementation and/or python-dev discussions.
1418
Tim Peters8dc73d22006-04-24 02:03:16 +00001419- Bug #1337990: clarified that ``doctest`` does not support examples
1420 requiring both expected output and an exception.
Anthony Baxter51bcb682006-04-05 14:51:42 +00001421

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001423What's New in Python 2.5 alpha 1?
1424=================================
1425
Anthony Baxterebed3f62006-04-03 15:03:44 +00001426*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001427
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001428Core and builtins
1429-----------------
1430
Nick Coghlan43832302006-04-23 17:04:07 +00001431- PEP 338: -m command line switch now delegates to runpy.run_module
1432 allowing it to support modules in packages and zipfiles
1433
Martin v. Löwisc661b882006-04-20 04:54:23 +00001434- On Windows, .DLL is not an accepted file name extension for
1435 extension modules anymore; extensions are only found if they
1436 end in .PYD.
1437
Martin v. Löwisea62d252006-04-03 10:56:49 +00001438- Bug #1421664: sys.stderr.encoding is now set to the same value as
1439 sys.stdout.encoding.
1440
Neal Norwitz92e212f2006-04-03 04:48:37 +00001441- __import__ accepts keyword arguments.
1442
Georg Brandlccadf842006-03-31 18:54:53 +00001443- Patch #1460496: round() now accepts keyword arguments.
1444
Anthony Baxter262c00a2006-03-30 10:53:17 +00001445- Fixed bug #1459029 - unicode reprs were double-escaped.
1446
Hye-Shik Changd478f342006-03-23 12:32:36 +00001447- Patch #1396919: The system scope threads are reenabled on FreeBSD
1448 5.4 and later versions.
1449
Neal Norwitze98ccf62006-03-23 05:39:47 +00001450- Bug #1115379: Compiling a Unicode string with an encoding declaration
1451 now gives a SyntaxError.
1452
Georg Brandlabd1ff82006-03-18 07:59:59 +00001453- Previously, Python code had no easy way to access the contents of a
1454 cell object. Now, a ``cell_contents`` attribute has been added
1455 (closes patch #1170323).
1456
Tim Peterscf79aac2006-03-16 01:14:46 +00001457- Patch #1123430: Python's small-object allocator now returns an arena to
1458 the system ``free()`` when all memory within an arena becomes unused
1459 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1460 freed. Some applications will see a drop in virtual memory size now,
1461 especially long-running applications that, from time to time, temporarily
1462 use a large number of small objects. Note that when Python returns an
1463 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001464 platform C library will in turn return that memory to the operating system.
1465 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001466 appears to be effective at least on Microsoft C and gcc-based systems.
1467 Thanks to Evan Jones for hard work and patience.
1468
Georg Brandl533ff6f2006-03-08 18:09:27 +00001469- Patch #1434038: property() now uses the getter's docstring if there is
1470 no "doc" argument given. This makes it possible to legitimately use
1471 property() as a decorator to produce a read-only property.
1472
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001473- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1474 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1475 of requiring an int or long in slicing and a few other contexts, enabling
1476 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1477
Neal Norwitz995acdf2006-03-07 05:01:00 +00001478- Fixed various bugs reported by Coverity's Prevent tool.
1479
Brett Cannonbf364092006-03-01 04:25:17 +00001480- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1481 new exception base class, BaseException, which has a new message attribute.
1482 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1483 Raising a string exception now raises a DeprecationWarning.
1484
Thomas Woutersfb609f42006-02-28 16:37:25 +00001485- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1486 explicitly relative, using 'from .module import name' to mean 'from the same
1487 package as this module is in. Imports without dots still default to the
1488 old relative-then-absolute, unless 'from __future__ import
1489 absolute_import' is used.
1490
Brett Cannona7446e32006-02-27 23:39:10 +00001491- Properly check if 'warnings' raises an exception (usually when a filter set
1492 to "error" is triggered) when raising a warning for raising string
1493 exceptions.
1494
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001495- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001496 The name was removed from Include/code.h.
1497
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001498- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001499
Guido van Rossum1968ad32006-02-25 22:38:04 +00001500- Patch 1433928:
1501 - The copy module now "copies" function objects (as atomic objects).
1502 - dict.__getitem__ now looks for a __missing__ hook before raising
1503 KeyError.
1504
Tim Peters84ef21c2006-02-28 20:39:06 +00001505- PEP 343: with statement implemented. Needs ``from __future__ import
1506 with_statement``. Use of 'with' as a variable will generate a warning.
1507 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001508 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001509 The following objects have __context__ methods:
1510 - The built-in file type.
1511 - The thread.LockType type.
1512 - The following types defined by the threading module:
1513 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1514 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001515
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001516- Fix the encodings package codec search function to only search
1517 inside its own package. Fixes problem reported in patch #1433198.
1518
1519 Note: Codec packages should implement and register their own
1520 codec search function. PEP 100 has the details.
1521
Tim Peters9ea89d22006-06-04 03:26:02 +00001522- PEP 353: Using ``Py_ssize_t`` as the index type.
1523
1524- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1525 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1526 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1527 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1528 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001529
Neal Norwitzfc76d632006-01-10 06:03:13 +00001530- Patch #1400181, fix unicode string formatting to not use the locale.
1531 This is how string objects work. u'%f' could use , instead of .
1532 for the decimal point. Now both strings and unicode always use periods.
1533
Neal Norwitz671b9e32006-01-09 07:07:12 +00001534- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1535 configure would break checking curses.h.
1536
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001537- Bug #959576: The pwd module is now builtin. This allows Python to be
1538 built on UNIX platforms without $HOME set.
1539
Neal Norwitzc10978f2005-12-19 06:07:16 +00001540- Bug #1072182, fix some potential problems if characters are signed.
1541
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001542- Bug #889500, fix line number on SyntaxWarning for global declarations.
1543
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001544- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1545
Neal Norwitze7214a12005-12-18 05:03:17 +00001546- Support for converting hex strings to floats no longer works.
1547 This was not portable. float('0x3') now raises a ValueError.
1548
Barry Warsaw2a38a862005-12-18 01:27:35 +00001549- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001550 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001551 is now displayed in interactive prompt banner.
1552
Georg Brandlfa166682005-12-17 21:45:17 +00001553- Implementation of PEP 341 - Unification of try/except and try/finally.
1554 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001555 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001556
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001557- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1558 now encodes backslash correctly.
1559
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001560- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1561
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001562- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001563 and long longs.
1564
Neal Norwitz67715f02005-11-09 06:59:35 +00001565- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001566 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001567 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001568
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001569- Replaced most Unicode charmap codecs with new ones using the
1570 new Unicode translate string feature in the builtin charmap
1571 codec; the codecs were created from the mapping tables available
1572 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1573 encodings now include a mapping for the Apple logo)
1574
Tim Peterse3547fd2005-12-16 23:13:57 +00001575- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001576
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001577- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001578
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001579- A new AST parser implementation was completed. The abstract
1580 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001581 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001582
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001583- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001584 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1585
Neal Norwitz708e51a2005-10-03 04:48:15 +00001586- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1587
Neal Norwitz11bd1192005-10-03 00:54:56 +00001588- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1589 Provide a warning when a directory is passed on the command line.
1590
Neal Norwitz40d37812005-10-02 01:48:49 +00001591- Fix segfault with invalid coding.
1592
1593- SF bug #772896: unknown encoding results in MemoryError.
1594
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001595- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001596 supported a __len__() method which evaluated to False when the iterator
1597 was empty.
1598
Guido van Rossum630db602005-09-20 18:49:54 +00001599- On 64-bit platforms, when __len__() returns a value that cannot be
1600 represented as a C int, raise OverflowError.
1601
Skip Montanarof8948ca2005-09-19 03:54:46 +00001602- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001603 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001604
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001605- SF bug #893549: parsing keyword arguments was broken with a few format
1606 codes.
1607
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001608- Changes donated by Elemental Security to make it work on AIX 5.3
1609 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1610 bug #105470: test_pwd fails on 64bit system (Opteron).
1611
Guido van Rossum539c6622005-09-14 17:49:54 +00001612- Changes donated by Elemental Security to make it work on HP-UX 11 on
1613 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1614
Georg Brandl4550b8d2005-08-26 06:43:52 +00001615- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001616 (fixes bug #1119418).
1617
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001618- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1619
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001620- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1621 exceptions that cause a function to exit.
1622
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001623- The implementation of set() and frozenset() was revised to use its
1624 own internal data structure. Memory consumption is reduced by 1/3
1625 and there are modest speed-ups as well. The API is unchanged.
1626
Tim Petersde7990b2005-07-17 23:45:23 +00001627- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1628
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001629- SF bug #1229429: PyObject_CallMethod failed to decrement some
1630 reference counts in some error exit cases.
1631
Tim Petersecc6e6a2005-07-10 22:30:55 +00001632- SF bug #1185883: Python's small-object memory allocator took over
1633 a block managed by the platform C library whenever a realloc specified
1634 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001635 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001636 portable way to copy data from the C-managed block into Python's
1637 small-object space without risking a memory fault. Python's small-object
1638 realloc now leaves such blocks under the control of the platform C
1639 realloc.
1640
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001641- SF bug #1232517: An overflow error was not detected properly when
1642 attempting to convert a large float to an int in os.utime().
1643
Raymond Hettinger3296e692005-06-29 23:29:56 +00001644- SF bug #1224347: hex longs now print with lowercase letters just
1645 like their int counterparts.
1646
Michael W. Hudson188d4362005-06-20 16:52:57 +00001647- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1648 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1649 interpreter states; back out that fix and do a better job (see
1650 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1651 for a longer write-up of the problem).
1652
Michael W. Hudsondf888462005-06-03 14:41:55 +00001653- SF patch #1180995: marshal now uses a binary format by default when
1654 serializing floats.
1655
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001656- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1657 the routines that promise to produce IEEE 754 binary representations
1658 of floats now simply copy bytes around.
1659
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001660- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1661 278.
1662
Brett Cannonc3647ac2005-04-26 03:45:26 +00001663- patch #1109424: int, long, float, complex, and unicode now check for the
1664 proper magic slot for type conversions when subclassed. Previously the
1665 magic slot was ignored during conversion. Semantics now match the way
1666 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001667 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001668 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001669 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001670
Barry Warsawc8d907c2005-04-19 23:43:40 +00001671- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1672 NULL, now raise an AttributeError when attempting to set or delete the
1673 attribute. Previously a TypeError was raised, but this was inconsistent
1674 with the equivalent pure-Python implementation.
1675
Michael W. Hudson774479c2005-04-18 08:46:17 +00001676- It is now safe to call PyGILState_Release() before
1677 PyEval_InitThreads() (note that if there is reason to believe there
1678 are multiple threads around you still must call PyEval_InitThreads()
1679 before using the Python API; this fix is for extension modules that
1680 have no way of knowing if Python is multi-threaded yet).
1681
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001682- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1683 disabled caused a crash.
1684
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001685- Bug #1165306: instancemethod_new allowed the creation of a method
1686 with im_class == im_self == NULL, which caused a crash when called.
1687
Tim Petersecc6e6a2005-07-10 22:30:55 +00001688- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001689 fixes the crash seen in bug #1165761
1690
Raymond Hettinger96229b12005-03-11 06:49:40 +00001691- Added two new builtins, any() and all().
1692
Brett Cannon409d8f22005-03-05 06:47:57 +00001693- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001694 (e.g., ``class C(): pass`` is no longer a syntax error).
1695 Patch #1176012 added support to the 'parser' module and 'compiler' package
1696 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001697
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001698- Patch #1115086: Support PY_LONGLONG in structmember.
1699
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001700- Bug #1155938: new style classes did not check that __init__() was
1701 returning None.
1702
Tim Petersecc6e6a2005-07-10 22:30:55 +00001703- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001704 ('\') with a specific error message.
1705
Martin v. Löwisff232d72005-03-03 09:24:38 +00001706- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1707
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001708- Bug #1124295: the __name__ attribute of file objects was
1709 inadvertently made inaccessible in restricted mode.
1710
Tim Petersecc6e6a2005-07-10 22:30:55 +00001711- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001712 an ferror() call.
1713
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001714- min() and max() now support key= arguments with the same meaning as in
1715 list.sort().
1716
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001717- The peephole optimizer now performs simple constant folding in expressions:
1718 (2+3) --> (5).
1719
Raymond Hettingera422c342005-01-11 03:03:27 +00001720- set and frozenset objects can now be marshalled. SF #1098985.
1721
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001722- Bug #1077106: Poor argument checking could cause memory corruption
1723 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001724
Jeremy Hyltonab630502005-02-04 18:44:06 +00001725- The parser did not complain about future statements in illegal
1726 positions. It once again reports a syntax error if a future
1727 statement occurs after anything other than a doc string.
1728
Neil Schemenauercf52c072005-08-12 17:34:58 +00001729- Change the %s format specifier for str objects so that it returns a
1730 unicode instance if the argument is not an instance of basestring and
1731 calling __str__ on the argument returns a unicode instance.
1732
Tim Petersf4e69282006-02-27 17:15:31 +00001733- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1734 current thread state when the auto-GIL-state machinery knows about
1735 it (since the thread state is being deleted, continuing to remember it
1736 can't help, but can hurt if another thread happens to get created with
1737 the same thread id).
1738
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001739Extension Modules
1740-----------------
1741
Georg Brandl43f08a82006-03-31 18:01:16 +00001742- Patch #1380952: fix SSL objects timing out on consecutive read()s
1743
Neal Norwitz05a45592006-03-20 06:30:08 +00001744- Patch #1309579: wait3 and wait4 were added to the posix module.
1745
Anthony Baxterfa869072006-03-20 05:21:58 +00001746- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1747 In addition, the existing ulaw code was updated.
1748
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001749- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00001750 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001751
Neal Norwitz10be10c2006-03-16 06:50:13 +00001752- Everything under lib-old was removed. This includes the following modules:
1753 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00001754 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001755 util, whatsound, whrandom, zmod
1756
1757- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1758
1759- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001760 is deprecated. The undocumented re.engine variable no longer exists.
1761
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001762- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1763 SS2 (single-shift 2) escape sequences correctly.
1764
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001765- The unicodedata module was updated to the 4.1 version of the Unicode
1766 database. The 3.2 version is still available as unicodedata.db_3_2_0
1767 for applications that require this specific version (such as IDNA).
1768
Neal Norwitzb62c4332006-03-04 18:35:47 +00001769- The timing module is no longer built by default. It was deprecated

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001929- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1930 been renamed to have only a single underscore prefix. This was done to
1931 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001932
Nick Coghlan43832302006-04-23 17:04:07 +00001933- PEP 338: new module runpy defines a run_module function to support
1934 executing modules which provide access to source code or a code object
1935 via the PEP 302 import mechanisms.
1936
Anthony Baxter93f5b932006-04-03 08:05:07 +00001937- The email module's parsedate_tz function now sets the daylight savings

1945 in attribute values.
1946
Anthony Baxterc51ee692006-04-01 00:57:31 +00001947- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001948 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001949 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001950 module will not be built.
1951
Tim Petersc17976e2006-04-01 00:26:53 +00001952- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1953 aren't officially supported here, and trying to use them will probably
1954 raise an exception some day. But dicts have been allowed, and "mostly
1955 worked", so support for them won't go away without warning.
1956
Georg Brandl338ef7d2006-03-31 18:42:16 +00001957- Bug #1445068: getpass.getpass() can now be given an explicit stream
1958 argument to specify where to write the prompt.

1975
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001976- email 4.0 package now integrated. This is largely the same as the email 3.0
1977 package that was included in Python 2.3, except that PEP 8 module names are
1978 now used (e.g. mail.message instead of email.Message). The MIME classes
1979 have been moved to a subpackage (e.g. email.mime.text instead of
1980 email.MIMEText). The old names are still supported for now. Several
1981 deprecated Message methods have been removed and lots of bugs have been
1982 fixed. More details can be found in the email package documentation.
1983
Walter Dörwald40108c92006-03-27 08:15:44 +00001984- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1985 (a subclass of tuple) that provides incremental decoders and encoders
1986 (a way to use stateful codecs without the stream API). Python functions
1987 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1988 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1989 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00001991- Patch #1359365: Calling next() on a closed StringIO.String object raises
1992 a ValueError instead of a StopIteration now (like file and cString.String do).
1993 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1994 called before (like file and StringIO.StringIO do).

2062
Neal Norwitz338e7862005-12-23 21:27:46 +00002063- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
2064 LoadError as documented, instead of IOError. For compatibility,
2065 LoadError subclasses IOError.
2066
Brett Cannon3cbd0382005-12-16 22:49:23 +00002067- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00002068 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2069 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2070 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2071 Ronald L. Rivest offered this advice for Python:
2072
2073 "The consensus of researchers in this area (at least as
2074 expressed at the NIST Hash Function Workshop 10/31/05),
2075 is that SHA-256 is a good choice for the time being, but
2076 that research should continue, and other alternatives may
2077 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002078
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002079- Added a subset of Fredrik Lundh's ElementTree package. Available

2132 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002133 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002134

2157
Georg Brandl9e43acf2005-07-04 17:16:07 +00002158- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2159 as this can cause problems with apps closing all file descriptors.

2173
Raymond Hettinger68c04532005-06-10 11:05:19 +00002174- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002175 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002176 the generate_tokens() function now accepts a callable argument that
2177 terminates by raising StopIteration.
2178
Georg Brandl9166e1a2005-06-04 09:20:03 +00002179- Bug #1196315: fix weakref.WeakValueDictionary constructor.

2196 instead of raising a TypeError when interacting with other types. This
2197 allows other classes to implement __radd__ style methods and have them
2198 work as expected.
2199
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002200- Bug #1163325: Decimal infinities failed to hash. Attempting to

Guido van Rossumd0641422005-02-03 15:01:24 +00002238- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2239 disables recursive traversal through instance attributes, which can
2240 be exploited in various ways.
2241
Tim Peterse3547fd2005-12-16 23:13:57 +00002242- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002243 flags on the HTTP listening socket.
2244

2254
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002255- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2256
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002257- Enhancements to the csv module:
2258
2259 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002260 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002261 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002262 + Dialect parameter parsing has been re-implemented to improve error
2263 reporting.
2264 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2265 dictates.
2266 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002267 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002268 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002269 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2270 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002271 + reader now allows \r characters to be quoted (previously it only allowed
2272 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002273 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002274 + Dialect classes passed to the module are no longer instantiated by
2275 the module before being parsed (the former validation scheme required
2276 this, but the mechanism was unreliable).
2277 + The dialect registry now contains instances of the internal
2278 C-coded dialect type, rather than references to python objects.
2279 + the internal c-coded dialect type is now immutable.
2280 + register_dialect now accepts the same keyword dialect specifications
2281 as the reader and writer, allowing the user to register dialects
2282 without first creating a dialect class.
2283 + a configurable limit to the size of parsed fields has been added -
2284 previously, an unmatched quote character could result in the entire
2285 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002286 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002287 the parser field size limit (returning the former limit). The initial
2288 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002289 + A line_num attribute has been added to the reader object, which tracks
2290 the number of lines read from the source iterator. This is not
2291 the same as the number of records returned, as records can span
2292 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002293 + reader and writer objects were not being registered with the cyclic-GC.
2294 This has been fixed.
2295
Brett Cannone6539c42005-01-08 02:43:53 +00002296- _DummyThread objects in the threading module now delete self.__block that is
2297 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2298 lock primitives tend to be limited in number and thus should not be wasted on
2299 a _DummyThread object. Fixes bug #1089632.
2300
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002301- The imghdr module now detects Exif files.
2302
Raymond Hettinger6065d322004-12-20 23:51:53 +00002303- StringIO.truncate() now correctly adjusts the size attribute.
2304 (Bug #951915).
2305
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002306- locale.py now uses an updated locale alias table (built using
2307 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2308 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002309 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002310
Raymond Hettinger3557f422004-12-07 12:02:02 +00002311- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2312
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002313- the pickle module no longer accepts the deprecated None option in the
2314 args tuple returned by __reduce__().
2315
Brett Cannon84667c02004-12-07 03:25:18 +00002316- optparse now optionally imports gettext. This allows its use in setup.py.
2317
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002318- the pickle module no longer uses the deprecated bin parameter.
2319
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002320- the shelve module no longer uses the deprecated binary parameter.
2321
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002322- the pstats module no longer uses the deprecated ignore() method.
2323
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002324- the filecmp module no longer uses the deprecated use_statcache argument.
2325
Raymond Hettinger664347b2004-12-04 21:21:53 +00002326- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2327 extended or overridden by subclasses. Formerly, the subclassed method would
2328 be ignored by the rest of the module. (Bug #1078905).
2329
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002330- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002331 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002332
Walter Dörwald36733692004-12-22 12:50:50 +00002333- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2334 once when a size argument is given. This prevents a buffer overflow in the
2335 tokenizer with very long source lines.
2336
Barry Warsaw538561e2006-01-01 21:48:54 +00002337- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2338 immediately after creating the object, without any intervening
2339 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002340
Skip Montanaro05885812005-01-16 20:48:27 +00002341- The reconvert.quote function can now emit triple-quoted strings. The
2342 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002343
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002344- ``UserString.MutableString`` now supports negative indices in
2345 ``__setitem__`` and ``__delitem__``
2346
Greg Ward40407942005-03-05 02:53:17 +00002347- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2348 correctly.
2349
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002350- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2351 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2352 character even if the user has passed a size parameter to get a proper
2353 line ending. Remove the special handling of a "\r\n" that has been split
2354 between two lines.
2355
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002356- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2357 about illegal code points. The codec now supports PEP 293 style error
2358 handlers.
2359
Walter Dörwald78a78b02005-09-01 12:04:29 +00002360- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002361 from the input stream, so that the output is a byte string in the correct
2362 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002363
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002364- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2365 considering it exactly like a '*'.
2366
Walter Dörwald007f8df2005-10-09 19:42:27 +00002367- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2368 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002369
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002370- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2371
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002372- Patch #1413711: Certain patterns of differences were making difflib
2373 touch the recursion limit.
2374
Walter Dörwald58917a62006-03-31 15:26:22 +00002375- Bug #947906: An object oriented interface has been added to the calendar
2376 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002377 called as a script (e.g. via ``python -mcalendar``). Localized month and
2378 weekday names can be ouput (even if an exotic encoding is used) using
2379 special classes that use unicode.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002381Build
2382-----
2383
Neal Norwitz602d3392006-03-31 08:21:40 +00002384- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2385 by using -mieee gcc option.
2386
Martin v. Löwis86d66262006-02-17 08:40:11 +00002387- Patch #1432345: Make python compile on DragonFly.
2388
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002389- Build support for Win64-AMD64 was added.
2390
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002391- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2392
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002393- Patch #881820: look for openpty and forkpty also in libbsd.
2394
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002395- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2396 The zlib module is now builtin on Windows.
2397
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002398- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2399
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002400- Bug #1189330: configure did not correctly determine the necessary
2401 value of LINKCC if python was built with GCC 4.0.
2402
Trent Mick8321b422005-07-26 02:29:21 +00002403- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2404 vulnerability in zlib 1.2.1 and 1.2.2.
2405
Brett Cannon08cd5982005-04-24 22:26:38 +00002406- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2407 flags that change binary compatibility. Changes were also made to
2408 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002409 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002410
Bob Ippolitoed233462005-03-29 13:47:59 +00002411- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2412 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2413 no longer exists). This configure patch makes things right.
2414
Martin v. Löwise2713be2005-03-08 15:03:08 +00002415- Bug #1158607: Build with --disable-unicode again.
2416
Brett Cannon46d96232005-02-16 00:07:19 +00002417- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2418 defined. Discovered as a result of not being able to build on OS X.
2419
Brett Cannon516592f2004-12-07 00:42:59 +00002420- setup.py now uses the directories specified in LDFLAGS using the -L option
2421 and in CPPFLAGS using the -I option for adding library and include
2422 directories, respectively, for compiling extension modules against. This has
2423 led to the core being compiled using the values in CPPFLAGS. It also removes
2424 the need for the special-casing of both DarwinPorts and Fink for darwin since
2425 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2426 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2427 Fink, ``-I/opt/local/include`` for DarwinPorts).
2428
Brett Cannon43802422005-02-10 20:48:03 +00002429- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2430 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2431 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2432 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002434C API
2435-----
2436
Tim Petersc9d78aa2006-03-26 23:27:58 +00002437- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2438 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2439 is obtained via the ``PyObject_`` family, it must be released via the
2440 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2441 always been officially true, but when Python's small-object allocator was
2442 introduced, an attempt was made to cater to a few extension modules
2443 discovered at the time that obtained memory via ``PyObject_New`` but
2444 released it via ``PyMem_DEL``. It's years later, and if such code still
2445 exists it will fail now (probably with segfaults, but calling wrong
2446 low-level memory management functions can yield many symptoms).
2447
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002448- Added a C API for set and frozenset objects.
2449
Raymond Hettinger66517482004-12-03 11:45:13 +00002450- Removed PyRange_New().
2451
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002452- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2453 mapping argument now. This string is used as a mapping table. Byte values
2454 greater than the length of the string and 0xFFFE are treated as undefined
2455 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002462
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002463- Patch #1276356: New resource "urlfetch" is implemented. This enables
