324-----------------
325
Neal Norwitz0bcafac2006-09-11 08:51:17 +0000326- Make _PyGILState_NoteThreadState() static, it was not used anywhere
327 outside of pystate.c and should not be necessary.
328
Brett Cannon19d76c52006-09-09 07:18:44 +0000329- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
330 allows calling unicode() on exceptions classes directly to succeed.
331
Georg Brandlecab6232006-09-06 06:47:02 +0000332- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

334 'exceptions'.
335
Georg Brandl37a9e572006-09-06 06:09:34 +0000336- Bug #1550983: emit better error messages for erroneous relative

Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000347- The return tuple from str.rpartition(sep) is (tail, sep, head) where
348 head is the original string if sep was not found.
349
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000350- Bug #1520864: unpacking singleton tuples in list comprehensions and
351 generator expressions (x for x, in ... ) works again. Fixing this problem
352 required changing the .pyc magic number. This means that .pyc files
353 generated before 2.5c2 will be regenerated.

456Core and builtins
457-----------------
458
Neal Norwitz24b6f202006-09-05 04:43:56 +0000459- Fix infinite recursion when subclassing long and overriding __hash__.
460
461- Fix concatenation (+=) of long strings.
462
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000463- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000464 compared equal or unequal to a string and a UnicodeDecodeError
465 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000466
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000467 Instead, the equal (==) and unequal (!=) comparison operators will
468 now issue a UnicodeWarning and interpret the two objects as
469 unequal. The UnicodeWarning can be filtered as desired using
470 the warning framework, e.g. silenced completely, turned into an
471 exception, logged, etc.
472
473 Note that compare operators other than equal and unequal will still
474 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000475
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000476- Fix segfault when doing string formatting on subclasses of long.
477
478- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
479 with new-style classes.
480
481- Fix bug related to __len__ functions returning negative values with
482 classic classes.
483
484- Patch #1538606, Fix __index__() clipping. There were some problems
485 discovered with the API and how integers that didn't fit into Py_ssize_t
486 were handled. This patch attempts to provide enough alternatives
487 to effectively use __index__.
488
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000489- Bug #1536021: __hash__ may now return long int; the final hash
490 value is obtained by invoking hash on the long int.
491
Thomas Hellerab1049c2006-08-08 17:37:00 +0000492- Bug #1536786: buffer comparison could emit a RuntimeWarning.

Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000494- Bug #1535165: fixed a segfault in input() and raw_input() when
495 sys.stdin is closed.
496
Thomas Heller74d36f02006-08-04 18:17:40 +0000497- On Windows, the PyErr_Warn function is now exported from
498 the Python dll again.
499
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000500- Bug #1191458: tracing over for loops now produces a line event
501 on each iteration. Fixing this problem required changing the .pyc
502 magic number. This means that .pyc files generated before 2.5c1
503 will be regenerated.
504
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000505- Bug #1333982: string/number constants were inappropriately stored
506 in the byte code and co_consts even if they were not used, ie
507 immediately popped off the stack.
508
Georg Brandle9462c72006-08-04 18:03:37 +0000509- Fixed a reference-counting problem in property().

512Library
513-------
514
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000515- Fix a bug in the ``compiler`` package that caused invalid code to be
516 generated for generator expressions.
517
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000518- The distutils version has been changed to 2.5.0. The change to
519 keep it programmatically in sync with the Python version running
520 the code (introduced in 2.5b3) has been reverted. It will continue
521 to be maintained manually as static string literal.
522
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000523- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000524 and this cannot be converted to the required C type, an exception is
525 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000526 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000527
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000528- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000529 an exception.
530
Tim Peterscbdd3502006-09-05 01:47:53 +0000531- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000532 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000533 workarounds for clocks with low resolution, to stop the code yielding
534 duplicate UUIDs.
535
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000536- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
537 before raising SystemExit, allowing IDLE to honor quit() and exit().
538
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000539- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
540
Georg Brandl7a1af772006-08-14 21:55:28 +0000541- Patch #1536071: trace.py should now find the full module name of a
542 file correctly even on Windows.
543
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000544- logging's atexit hook now runs even if the rest of the module has
545 already been cleaned up.
546
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000547- Bug #1112549, fix DoS attack on cgi.FieldStorage.

Neal Norwitzff4b63b2006-08-04 04:50:21 +0000549- Bug #1531405, format_exception no longer raises an exception if
550 str(exception) raised an exception.
551
Neil Schemenauer06ded092006-08-04 16:20:30 +0000552- Fix a bug in the ``compiler`` package that caused invalid code to be
553 generated for nested functions.

565
Thomas Heller1ce433e2006-08-14 16:20:04 +0000566- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
567 '-no-stack-protector' compiler flag for OpenBSD has been removed.
568
Thomas Heller86720042006-08-14 11:17:48 +0000569- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
570 uses the _as_parameter_ attribute when objects are passed to foreign
571 function calls. The ctypes version number was changed to 1.0.1.
572
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000573- Bug #1530559, struct.pack raises TypeError where it used to convert.
574 Passing float arguments to struct.pack when integers are expected
575 now triggers a DeprecationWarning.

Fred Drake53912162006-07-29 13:22:49 +0000620What's New in Python 2.5 beta 3?
621================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000622
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000623*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000624
625Core and builtins
626-----------------
627
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000628- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000629 returned a long (see PEP 353).
630
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000631- Bug #1515471: string.replace() accepts character buffers again.
632
Neal Norwitz07aadb12006-07-30 06:55:48 +0000633- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
634 This provides the proper warning for struct.pack().
635 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
636
Neal Norwitz0d62a062006-07-30 06:53:31 +0000637- Patch #1531113: Fix augmented assignment with yield expressions.
638 Also fix a SystemError when trying to assign to yield expressions.
639
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000640- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
641 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
642 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
643 excessive filesystem operations during imports.
644
Tim Petersbc24eee2006-07-27 01:14:53 +0000645- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
646 operations on signed longs that are formally undefined by C.
647 Unfortunately, at least one compiler now cares about that, so complicated
648 the code to make that compiler happy again.
649
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000650- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
651
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000652- Patch #1232023: Stop including current directory in search
653 path on Windows.
654
Neal Norwitze1fdb322006-07-21 05:32:28 +0000655- Fix some potential crashes found with failmalloc.
656
Neal Norwitze7563102006-07-17 01:00:16 +0000657- Fix warnings reported by Klocwork's static analysis tool.
658
Neal Norwitz84be93b2006-07-16 01:50:38 +0000659- Bug #1512814, Fix incorrect lineno's when code within a function
660 had more than 255 blank lines.
661
Georg Brandl9dceedb2006-07-12 15:31:17 +0000662- Patch #1521179: Python now accepts the standard options ``--help`` and
663 ``--version`` as well as ``/?`` on Windows.
664
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000665- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000666 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000667 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000668
Tim Peters112aad32006-07-19 00:03:19 +0000669- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000670 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000671 new ``sys._current_frames()`` returns a dictionary with one entry,
672 mapping the faux "thread id" 0 to the current frame.
673
Ronald Oussoren3075e162006-07-25 20:28:55 +0000674- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000675
Ronald Oussoren3075e162006-07-25 20:28:55 +0000676
Neal Norwitza1f10902006-07-12 07:28:29 +0000677Library
678-------
679
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000680- Correction of patch #1455898: In the mbcs decoder, set final=False
681 for stream decoder, but final=True for the decode function.
682
Georg Brandl07fec3a2006-08-01 18:49:24 +0000683- os.urandom no longer masks unrelated exceptions like SystemExit or
684 KeyboardInterrupt.
685
Tim Peters4643c2f2006-08-10 22:45:34 +0000686- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000687 shutil.copytree on Windows
688
Georg Brandle34ac7c2006-07-30 11:07:23 +0000689- Bug #1002398: The documentation for os.path.sameopenfile now correctly
690 refers to file descriptors, not file objects.
691
Tim Peterscbdd3502006-09-05 01:47:53 +0000692- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000693 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000694 #1513611, and probably others.
695
Georg Brandledd9b0d2006-07-29 09:33:26 +0000696- Bug #1441397: The compiler module now recognizes module and function
697 docstrings correctly as it did in Python 2.4.
698
Tim Peters6f681472006-07-27 23:44:37 +0000699- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
700 lost that tests are sorted by name before being run. This rarely
701 matters for well-written tests, but can create baffling symptoms if
702 side effects from one test to the next affect outcomes. ``DocTestFinder``
703 has been changed to sort the list of tests it returns.
704
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000705- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000706 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000707
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000708- Bug #978833: Really close underlying socket in _socketobject.close.
709
Georg Brandldb232dc2006-08-20 13:15:43 +0000710- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
711 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000712
Georg Brandlcf0c1722006-07-26 07:23:32 +0000713- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
714 to recursive calls and call it with the failing package name.
715
Martin v. Löwis0b483032006-07-25 09:53:12 +0000716- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
717
Georg Brandlc13c34c2006-07-24 14:09:56 +0000718- Patch #1515343: Fix printing of deprecated string exceptions with a
719 value in the traceback module.
720
Greg Ward48fae7a2006-07-23 16:05:51 +0000721- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
722
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000723- Patch #1524429: Use repr() instead of backticks in Tkinter again.
724
Brett Cannoncaebe222006-07-18 04:41:36 +0000725- Bug #1520914: Change time.strftime() to accept a zero for any position in its
726 argument tuple. For arguments where zero is illegal, the value is forced to
727 the minimum value that is correct. This is to support an undocumented but
728 common way people used to fill in inconsequential information in the time
729 tuple pre-2.4.
730
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000731- Patch #1220874: Update the binhex module for Mach-O.
732
Barry Warsawb110bad2006-07-21 14:51:07 +0000733- The email package has improved RFC 2231 support, specifically for
734 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
735 (name*0=<blah>) parameter continuations. This may change the types of
736 values returned from email.message.Message.get_param() and friends.
737 Specifically in some cases where non-encoded continuations were used,
738 get_param() used to return a 3-tuple of (None, None, string) whereas now it
739 will just return the string (since non-encoded continuations don't have
740 charset and language parts).
741
742 Also, whereas % values were decoded in all parameter continuations, they are
743 now only decoded in encoded parameter parts.
744
Ronald Oussoren3075e162006-07-25 20:28:55 +0000745- Bug #1517990: IDLE keybindings on MacOS X now work correctly
746
747- Bug #1517996: IDLE now longer shows the default Tk menu when a
748 path browser, class browser or debugger is the frontmost window on MacOS X
749
Barry Warsaw00decd72006-07-27 23:43:15 +0000750- Patch #1520294: Support for getset and member descriptors in types.py,
751 inspect.py, and pydoc.py. Specifically, this allows for querying the type
752 of an object against these built-in types and more importantly, for getting
753 their docstrings printed in the interactive interpreter's help() function.
754
Ronald Oussoren3075e162006-07-25 20:28:55 +0000755
Neal Norwitza1f10902006-07-12 07:28:29 +0000756Extension Modules
757-----------------
758
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000759- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
760 a socket operation on a socket with a timeout, the exception will be
761 caught correctly. Previously, the exception was not caught.
762
Thomas Heller1393d6a2006-07-28 21:43:20 +0000763- Patch #1529514: The _ctypes extension is now compiled on more
764 openbsd target platforms.
765
Tim Peters9cab5932006-07-28 00:30:00 +0000766- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
767 a memory leak, affecting pickles and deep copies.
768
Tim Petersbc24eee2006-07-27 01:14:53 +0000769- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000770 Paul Eggert.
771
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000772- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
773
Thomas Hellerce049a02006-07-14 17:51:14 +0000774- Patch #1521817: Index range checking on ctypes arrays containing
775 exactly one element enabled again. This allows iterating over these
776 arrays, without the need to check the array size before.
777
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000778- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000779 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000780 /dev/null in certain cases; this is now fixed.
781
Thomas Heller47d7a062006-07-12 08:43:47 +0000782- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
783 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000784
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000785- Because of a misspelled preprocessor symbol, ctypes was always
786 compiled without thread support; this is now fixed.
787
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000788- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
789 methods now allow their database parameter to be None as the
790 sleepycat API allows.
791
Matt Flemingec926502006-07-28 11:27:27 +0000792- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
793 bluetooth API compared with Linux and FreeBSD.
794
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000795Tests
796-----
797
798- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
799 how long the test file should take to play. Now accepts taking 2.93 secs
800 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
801
Georg Brandl4793aa32006-07-28 18:31:39 +0000802- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
803 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
804 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +0000805
Martin v. Löwis0907f4d2006-07-30 14:09:47 +0000806Build
807-----
808
809- Bug #1439538: Drop usage of test -e in configure as it is not portable.
810
Ronald Oussoren26cad082006-08-01 21:00:57 +0000811Mac
812---
813
814- PythonLauncher now works correctly when the path to the script contains
815 characters that are treated specially by the shell (such as quotes).
816
817- Bug #1527397: PythonLauncher now launches scripts with the working directory
818 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000819 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000820 expect.
821
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000822
Georg Brandlad29e632006-06-21 17:45:17 +0000823What's New in Python 2.5 beta 2?
824================================

Anthony Baxter70e8e872006-07-10 07:41:04 +0000826*Release date: 11-JUL-2006*
Georg Brandlad29e632006-06-21 17:45:17 +0000827
828Core and builtins
829-----------------
830
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000831- Bug #1441486: The literal representation of -(sys.maxint - 1)
832 again evaluates to a int object, not a long.
833
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000834- Bug #1501934: The scope of global variables that are locally assigned
835 using augmented assignment is now correctly determined.
836
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000837- Bug #927248: Recursive method-wrapper objects can now safely
838 be released.
839
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000840- Bug #1417699: Reject locale-specific decimal point in float()
841 and atof().
842
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000843- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
844 omit a default "error" argument for NULL pointer. This allows
845 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000846
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000847- Bug #1519018: 'as' is now validated properly in import statements.
848
Neal Norwitz28746ab2006-07-09 22:14:42 +0000849- On 64 bit systems, int literals that use less than 64 bits are
850 now ints rather than longs.
851
Neal Norwitzed657552006-07-10 00:04:44 +0000852- Bug #1512814, Fix incorrect lineno's when code at module scope
853 started after line 256.
854
Tim Peters32a83612006-07-10 21:08:24 +0000855- New function ``sys._current_frames()`` returns a dict mapping thread
856 id to topmost thread stack frame. This is for expert use, and is
857 especially useful for debugging application deadlocks. The functionality
858 was previously available in Fazal Majid's ``threadframe`` extension
859 module, but it wasn't possible to do this in a wholly threadsafe way from
860 an extension.
861
Georg Brandlad29e632006-06-21 17:45:17 +0000862Library
863-------
864
Martin v. Löwis77621582006-07-30 13:27:31 +0000865- Bug #1257728: Mention Cygwin in distutils error message about a missing

869
Tim Peters32a83612006-07-10 21:08:24 +0000870- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000871 environment variable to be set in order to the SDK environment
872 for finding the compiler, include files, etc.
873

Nick Coghlan2d792252006-07-06 13:47:18 +0000876- warnings.py now ignores ImportWarning by default
877
Thomas Woutersadd19112006-07-05 11:03:49 +0000878- string.Template() now correctly handles tuple-values. Previously,
879 multi-value tuples would raise an exception and single-value tuples would
880 be treated as the value they contain, instead.
881
Martin v. Löwisede77f52006-07-03 13:01:35 +0000882- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
883 even if some data are received.
884
Martin v. Löwis45482392006-07-03 12:28:58 +0000885- Bug #1267547: Put proper recursive setup.py call into the
886 spec file generated by bdist_rpm.

889 degrees and radians.
890
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000891- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000892 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000893
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000894- Bug #1514703: Only setup canvas window in turtle when the canvas
895 is created.
896
Martin v. Löwis7596e832006-07-01 15:33:37 +0000897- Bug #1513223: .close() of a _socketobj now releases the underlying
898 socket again, which then gets closed as it becomes unreferenced.
899
Fred Drake10497c82006-06-29 02:57:48 +0000900- Bug #1504333: Make sgmllib support angle brackets in quoted
901 attribute values.
902
903- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
904 sgmllib ('[' and ']' were not accepted).
905
Georg Brandl1be63af2006-06-28 20:23:25 +0000906- Fix a bug in the turtle module's end_fill function.
907
Brett Cannon53ab5b72006-06-22 16:49:14 +0000908- Bug #1510580: The 'warnings' module improperly required that a Warning
909 category be either a types.ClassType and a subclass of Warning. The proper
910 check is just that it is a subclass with Warning as the documentation states.
911
Georg Brandlad29e632006-06-21 17:45:17 +0000912- The compiler module now correctly compiles the new try-except-finally
913 statement (bug #1509132).
914
Neal Norwitz60373cd2006-06-22 06:30:50 +0000915- The wsgiref package is now installed properly on Unix.
916
Vinay Sajip28e57612006-07-01 10:45:20 +0000917- A bug was fixed in logging.config.fileConfig() which caused a crash on
918 shutdown when fileConfig() was called multiple times.
919
Gerhard Häring762fbd32006-07-02 17:48:30 +0000920- The sqlite3 module did cut off data from the SQLite database at the first
921 null character before sending it to a custom converter. This has been fixed
922 now.

925-----------------
926
Tim Peters112aad32006-07-19 00:03:19 +0000927- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
928 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
929 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000930
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000931- Assigning None to pointer type fields in ctypes structures possible
932 overwrote the wrong fields, this is fixed now.
933
934- Fixed a segfault in _ctypes when ctypes.wintypes were imported
935 on non-Windows platforms.
936
937- Bug #1518190: The ctypes.c_void_p constructor now accepts any
938 integer or long, without range checking.
939
940- Patch #1517790: It is now possible to use custom objects in the ctypes
941 foreign function argtypes sequence as long as they provide a from_param
942 method, no longer is it required that the object is a ctypes type.
943
944- The '_ctypes' extension module now works when Python is configured
945 with the --without-threads option.
946
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000947- Bug #1513646: os.access on Windows now correctly determines write
948 access, again.
949
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000950- Bug #1512695: cPickle.loads could crash if it was interrupted with
951 a KeyboardInterrupt.
952
Neal Norwitza12aa882006-07-06 06:45:08 +0000953- Bug #1296433: parsing XML with a non-default encoding and
954 a CharacterDataHandler could crash the interpreter in pyexpat.
955

962
Tim Peters32a83612006-07-10 21:08:24 +0000963- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000964 Previously, the slight difference could cause compilation errors of the
965 'zlib' module on systems with more than one version of zlib.
966
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000967- The MSI compileall step was fixed to also support a TARGETDIR

998Core and builtins
999-----------------
1000
Georg Brandla56b9152006-06-19 06:35:54 +00001001- Patch #1507676: Error messages returned by invalid abstract object operations
1002 (such as iterating over an integer) have been improved and now include the
1003 type of the offending object to help with debugging.
1004
Brett Cannonea3912b2006-06-13 21:46:41 +00001005- Bug #992017: A classic class that defined a __coerce__() method that returned
1006 its arguments swapped would infinitely recurse and segfault the interpreter.
1007
Neal Norwitz909eb122006-06-12 02:13:21 +00001008- Fix the socket tests so they can be run concurrently.
1009
Neal Norwitzb9845e72006-06-12 02:11:18 +00001010- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001011 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001012
Brett Cannon22565aa2006-06-09 22:31:23 +00001013- Bug #532646: object.__call__() will continue looking for the __call__
1014 attribute on objects until one without one is found. This leads to recursion
1015 when you take a class and set its __call__ attribute to an instance of the
1016 class. Originally fixed for classic classes, but this fix is for new-style.
1017 Removes the infinite_rec_3 crasher.
1018
Georg Brandl24250812006-06-09 18:45:48 +00001019- The string and unicode methods startswith() and endswith() now accept
1020 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1021
Brett Cannonde3b0522006-06-08 17:00:45 +00001022- Buffer objects, at the C level, never used the char buffer
1023 implementation even when the char buffer for the wrapped object was
1024 explicitly requested (originally returned the read or write buffer).
1025 Now a TypeError is raised if the char buffer is not present but is
1026 requested.
1027
Georg Brandlddbaa662006-06-04 21:56:52 +00001028- Patch #1346214: Statements like "if 0: suite" are now again optimized
1029 away like they were in Python 2.4.
1030
Georg Brandlb7c8f542006-05-27 12:30:25 +00001031- Builtin exceptions are now full-blown new-style classes instead of
1032 instances pretending to be classes, which speeds up exception handling
1033 by about 80% in comparison to 2.5a2.
1034
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001035- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1036 Unicode 4.1.
1037
Georg Brandlf4ef1162006-05-26 18:03:31 +00001038- Patch #921466: sys.path_importer_cache is now used to cache valid and
1039 invalid file paths for the built-in import machinery which leads to
1040 fewer open calls on startup.
1041
Tim Peters696cf432006-05-24 21:10:40 +00001042- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1043 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1044 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1045 the number of input digits (it was and remains linear-time for bases
1046 2, 4, 8, 16 and 32).
1047
Tim Petersb713ec22006-05-23 18:45:30 +00001048- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1049 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1050 an integer close to ``sys.maxint``. This was repaired by patch
1051 #1335972, which also gives a nice speedup.
1052
Richard Jonescebbefc2006-05-23 18:28:17 +00001053- Patch #1337051: reduced size of frame objects.
1054
1055- PyErr_NewException now accepts a tuple of base classes as its
1056 "base" parameter.
1057
Richard Jones7c88dcc2006-05-23 10:37:38 +00001058- Patch #876206: function call speedup by retaining allocated frame
1059 objects.
1060
Georg Brandl7b90e162006-05-18 07:01:27 +00001061- Bug #1462152: file() now checks more thoroughly for invalid mode
1062 strings and removes a possible "U" before passing the mode to the
1063 C library function.
1064
Neal Norwitz1004a532006-05-15 07:17:23 +00001065- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1066
Neal Norwitz373f0a72006-05-15 07:04:36 +00001067- Bug #1487966: Fix SystemError with conditional expression in assignment
1068
Martin v. Löwis879768d2006-05-11 13:28:43 +00001069- WindowsError now has two error code attributes: errno, which carries
1070 the error values from errno.h, and winerror, which carries the error
1071 values from winerror.h. Previous versions put the winerror.h values
1072 (from GetLastError()) into the errno attribute.
1073
Martin v. Löwis77736712006-05-04 05:51:03 +00001074- Patch #1475845: Raise IndentationError for unexpected indent.
1075
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001076- Patch #1479181: split open() and file() from being aliases for each other.
1077
Tim Peters44bd9862006-06-01 13:49:23 +00001078- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1079 methods were always silently ignored by dictionaries when comparing keys.
1080 They are now passed through (except when using the C API function
1081 ``PyDict_GetItem()``, whose semantics did not change).
1082
1083- Bug #1456209: In some obscure cases it was possible for a class with a
1084 custom ``__eq__()`` method to confuse dict internals when class instances
1085 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1086 No, you don't have any code that did this ;-)

1093- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1094
Brett Cannon6ee7d012006-06-08 16:23:04 +00001095- Change binascii.hexlify to accept a read-only buffer instead of only a char
1096 buffer and actually follow its documentation.
1097
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001098- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1099
Nick Coghlanc649ec52006-05-29 12:43:05 +00001100- Patch #1478788 (modified version): The functional extension module has
1101 been renamed to _functools and a functools Python wrapper module added.
1102 This provides a home for additional function related utilities that are
1103 not specifically about functional programming. See PEP 309.
1104
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001105- Patch #1493701: performance enhancements for struct module.

Georg Brandl8d3342b2006-05-16 07:38:27 +00001109- Patch #1435422: zlib's compress and decompress objects now have a
1110 copy() method.
1111
Andrew MacIntyre92913322006-06-13 15:04:24 +00001112- Patch #1454481: thread stack size is now tunable at runtime for thread
1113 enabled builds on Windows and systems with Posix threads support.
1114
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001115- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1116 (up to the system limit of 32K characters).
1117
1118- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1119 As a result, these functions now raise WindowsError instead of OSError.
1120
Tim Peters7a822da2006-05-25 21:50:17 +00001121- ``time.clock()`` on Win64 should use the high-performance Windows
1122 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1123 Windows platforms).
1124
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001125- Calling Tk_Init twice is refused if the first call failed as that
1126 may deadlock.
1127
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001128- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1129 accept it without potentially using an uninitialized pointer.
1130
1131- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1132 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

Gregory P. Smith372b5832006-06-05 18:48:21 +00001138- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1139 parameter is supplied. [SF pybsddb bug #1477863]
1140
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001141- bsddb: the __len__ method of a DB object has been fixed to return correct
1142 results. It could previously incorrectly return 0 in some cases.
1143 Fixes SF bug 1493322 (pybsddb bug 1184012).
1144
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001145- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1146 aborts the db transaction safely when a modifier callback fails.
1147 Fixes SF python patch/bug #1408584.
1148
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001149- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001150 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001151 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1152 database calls that would previously deadlock. [SF python bug #775414]

1182 double-byte encodings.
1183
Tim Peters43898b42006-06-14 04:09:25 +00001184- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1185 guarantee that adjacent triples in the return list always describe
1186 non-adjacent blocks. Previously, a pair of matching blocks could end
1187 up being described by multiple adjacent triples that formed a partition
1188 of the matching pair.
1189
Greg Ward0e0c9f42006-06-11 16:24:11 +00001190- Bug #1498146: fix optparse to handle Unicode strings in option help,

Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001198- The wsgiref package has been added to the standard library.
1199
Nick Coghlan676725d2006-06-08 13:54:49 +00001200- The functions update_wrapper() and wraps() have been added to the functools
1201 module. These make it easier to copy relevant metadata from the original
1202 function when writing wrapper functions.
1203
Tim Petersd6a9eef2006-06-05 01:48:21 +00001204- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1205 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001206
Martin v. Löwis3f767792006-06-04 19:36:28 +00001207- Patch #1359618: Speed up charmap encoder by using a trie structure
1208 for lookup.
1209
Tim Petersd609b1a2006-06-02 23:22:51 +00001210- The functions in the ``pprint`` module now sort dictionaries by key
1211 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1212 if and only if its display required more than one line, although that
1213 wasn't documented. The new behavior increases predictability; e.g.,
1214 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1215
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001216- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1217 (thanks for J. J. Lee).
1218
Georg Brandl2b330372006-05-28 20:23:12 +00001219- Patch #1496206: improve urllib2 handling of passwords with respect to
1220 default HTTP and HTTPS ports.
1221
George Yoshidaf3c65de2006-05-28 16:39:09 +00001222- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1223
Bob Ippolito7298f272006-05-23 18:43:47 +00001224- Patch #1281707: speed up gzip.readline.
1225
Georg Brandlb89316f2006-05-17 15:51:16 +00001226- Patch #1180296: Two new functions were added to the locale module:
1227 format_string() to get the effect of "format % items" but locale-aware,
1228 and currency() to format a monetary number with currency sign.
1229
Georg Brandle3a25832006-05-17 14:56:04 +00001230- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1231 and several features added, such as speed and geometry control.
1232
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001233- Patch #1488881: add support for external file objects in bz2 compressed
1234 tarfiles.
1235
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001236- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1237 stdout arguments, making it possible to redirect input and output
1238 for remote debugging.
1239
1240- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1241 a couple of issues, notably handling of long file names using the
1242 GNU LONGNAME extension.
1243
1244- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1245 new flag when ``name`` is already the name of an option flag.
1246
1247- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1248 package.
1249
1250- Patch #1472854: make the rlcompleter.Completer class usable on non-
1251 UNIX platforms.
1252
1253- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1254
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001255- Bug #1472827: correctly escape newlines and tabs in attribute values in
1256 the saxutils.XMLGenerator class.

1265
Martin v. Löwisa43190b2006-05-22 09:15:18 +00001266- Patch #1492356: Port to Windows CE.
1267
Neal Norwitz58e28882006-05-19 07:00:58 +00001268- Bug/Patch #1481770: Use .so extension for shared libraries on HP-UX for ia64.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001286What's New in Python 2.5 alpha 2?
1287=================================
1288
1289*Release date: 27-APR-2006*
1290
1291Core and builtins
1292-----------------
1293
Thomas Heller1b046642006-04-18 18:51:06 +00001294- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1295 by converting these apis from macros into exported functions again:
1296
1297 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1298 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1299 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1300 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1301 PyRun_String Py_CompileString
1302
Martin v. Löwis45294a92006-04-18 06:24:08 +00001303- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1304
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001305- All uses of PyStructSequence_InitType have been changed to initialize
1306 the type objects only once, even if the interpreter is initialized
1307 multiple times.
1308
Neal Norwitz61546162006-04-14 05:20:28 +00001309- Bug #1454485, array.array('u') could crash the interpreter. This was
1310 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1311 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1312
1313- Py_UNICODE is unsigned. It was always documented as unsigned, but
1314 due to a bug had a signed value in previous versions.
1315
Tim Peters3a5e8b12006-04-11 01:44:07 +00001316- Patch #837242: ``id()`` of any Python object always gives a positive
1317 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1318 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001319 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001320 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001321
Tim Peters3a5e8b12006-04-11 01:44:07 +00001322 def __hash__(self):
1323 return id(self) # WRONG
1324
1325 because a hash result must be a (short) Python int but it was always
1326 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001327 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001328 was always usable as a hash value before this patch. That's no longer
1329 necessarily so.
1330
1331- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001332 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001333 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001334 #1454844)
1335
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001336- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1337 involving generators that have paused outside of any ``try`` or ``with``
1338 blocks. (In 2.5a1, a paused generator that was part of a reference
1339 cycle could not be garbage collected, regardless of whether it was
1340 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001341
Anthony Baxter51bcb682006-04-05 14:51:42 +00001342Extension Modules

1344
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001345- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1346 is a macro.
1347
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001348- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1349 fails with an error condition.
1350
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001351- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1352
1353- Bug #1117761: bsddb.*open() no longer raises an exception when using
1354 the cachesize parameter.
1355
1356- Bug #1149413: bsddb.*open() no longer raises an exception when using
1357 a temporary db (file=None) with the 'n' flag to truncate on open.
1358
1359- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1360 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001361
Armin Rigoa9017c32006-04-19 11:50:27 +00001362- Patch #1062014: AF_UNIX sockets under Linux have a special
1363 abstract namespace that is now fully supported.

1366-------
1367
Peter Astrand7d1d4362006-07-14 14:04:45 +00001368- Bug #1223937: subprocess.CalledProcessError reports the exit status
1369 of the process using the returncode attribute, instead of
1370 abusing errno.
1371
Tim Peters711bf302006-04-25 03:31:36 +00001372- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1373 a doctest to be skipped (the code is not run, and the expected output
1374 or exception is ignored).
1375
Nick Coghlanda2268f2006-04-24 04:37:15 +00001376- Fixed contextlib.nested to cope with exceptions being raised and
1377 caught inside exit handlers.
1378
Greg Wardab05edc2006-04-23 03:47:58 +00001379- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1380 hex, octal, or binary; add ``append_const`` action; keep going if
1381 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1382 added ``epilog`` for better help generation).
1383
Tim Peters21fbd572006-04-21 21:18:10 +00001384- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1385 called from a thread spawned as a side effect of importing a module.
1386
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001387- The pydoc module now supports documenting packages contained in
1388 .zip or .egg files.
1389
1390- The pkgutil module now has several new utility functions, such
1391 as ``walk_packages()`` to support working with packages that are either
1392 in the filesystem or zip files.
1393
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001394- The mailbox module can now modify and delete messages from
1395 mailboxes, in addition to simply reading them. Thanks to Gregory
1396 K. Johnson for writing the code, and to the 2005 Google Summer of
1397 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001398
Tim Petersc7605f22006-04-17 21:12:33 +00001399- The ``__del__`` method of class ``local`` in module ``_threading_local``
1400 returned before accomplishing any of its intended cleanup.
1401
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001402- Patch #790710: Add breakpoint command lists in pdb.
1403
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001404- Patch #1063914: Add Tkinter.Misc.clipboard_get().

1407
Anthony Baxtere29002c2006-04-12 12:07:31 +00001408- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1409 Windows. Bug #1469163.
1410
Phillip J. Eby47032112006-04-11 01:07:43 +00001411- The warnings, linecache, inspect, traceback, site, and doctest modules
1412 were updated to work correctly with modules imported from zipfiles or
1413 via other PEP 302 __loader__ objects.
1414
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001415- Patch #1467770: Reduce usage of subprocess._active to processes which
1416 the application hasn't waited on.

1423 direct output to an alternate file-like object.
1424

1426-----
1427
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001428- The Makefile now has a reindent target, which runs reindent.py on
1429 the library.
1430
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001431- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis0f48d982006-04-14 14:34:26 +00001435- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1436 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001437 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001438 CXX from --with-cxx-main, see description in README.
1439
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001440- Patch #1429775: Link extension modules with the shared libpython.
1441
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001442- Fixed a libffi build problem on MIPS systems.
1443
Tim Peters8931ff12006-05-13 23:28:20 +00001444- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1445 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1446 and "%zu" for unsigned integers of type ``size_t``.
1447
Anthony Baxter51bcb682006-04-05 14:51:42 +00001448Tests
1449-----
1450
Nick Coghlanda2268f2006-04-24 04:37:15 +00001451- test_contextlib now checks contextlib.nested can cope with exceptions
1452 being raised and caught inside exit handlers.
1453
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001454- test_cmd_line now checks operation of the -m and -c command switches
1455
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001456- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1457 it separately and by hand. It also wasn't cleaning up its changes to
1458 the current Decimal context.
1459
Thomas Woutersabd08882006-04-26 15:53:30 +00001460- regrtest.py now has a -M option to run tests that test the new limits of
1461 containers, on 64-bit architectures. Running these tests is only sensible
1462 on 64-bit machines with more than two gigabytes of memory. The argument
1463 passed is the maximum amount of memory for the tests to use.

1475
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001476- PEP 343: Added Context Types section to the library reference
1477 and attempted to bring other PEP 343 related documentation into
1478 line with the implementation and/or python-dev discussions.
1479
Tim Peters8dc73d22006-04-24 02:03:16 +00001480- Bug #1337990: clarified that ``doctest`` does not support examples

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001484What's New in Python 2.5 alpha 1?
1485=================================
1486
Anthony Baxterebed3f62006-04-03 15:03:44 +00001487*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001488
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001489Core and builtins
1490-----------------
1491
Nick Coghlan43832302006-04-23 17:04:07 +00001492- PEP 338: -m command line switch now delegates to runpy.run_module

1494
Martin v. Löwisc661b882006-04-20 04:54:23 +00001495- On Windows, .DLL is not an accepted file name extension for
1496 extension modules anymore; extensions are only found if they
1497 end in .PYD.
1498
Martin v. Löwisea62d252006-04-03 10:56:49 +00001499- Bug #1421664: sys.stderr.encoding is now set to the same value as
1500 sys.stdout.encoding.
1501
Neal Norwitz92e212f2006-04-03 04:48:37 +00001502- __import__ accepts keyword arguments.

1505
Anthony Baxter262c00a2006-03-30 10:53:17 +00001506- Fixed bug #1459029 - unicode reprs were double-escaped.
1507
Hye-Shik Changd478f342006-03-23 12:32:36 +00001508- Patch #1396919: The system scope threads are reenabled on FreeBSD
1509 5.4 and later versions.
1510
Neal Norwitze98ccf62006-03-23 05:39:47 +00001511- Bug #1115379: Compiling a Unicode string with an encoding declaration
1512 now gives a SyntaxError.
1513
Georg Brandlabd1ff82006-03-18 07:59:59 +00001514- Previously, Python code had no easy way to access the contents of a
1515 cell object. Now, a ``cell_contents`` attribute has been added
1516 (closes patch #1170323).
1517
Tim Peterscf79aac2006-03-16 01:14:46 +00001518- Patch #1123430: Python's small-object allocator now returns an arena to
1519 the system ``free()`` when all memory within an arena becomes unused
1520 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1521 freed. Some applications will see a drop in virtual memory size now,
1522 especially long-running applications that, from time to time, temporarily
1523 use a large number of small objects. Note that when Python returns an
1524 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001525 platform C library will in turn return that memory to the operating system.
1526 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001527 appears to be effective at least on Microsoft C and gcc-based systems.
1528 Thanks to Evan Jones for hard work and patience.
1529
Georg Brandl533ff6f2006-03-08 18:09:27 +00001530- Patch #1434038: property() now uses the getter's docstring if there is
1531 no "doc" argument given. This makes it possible to legitimately use
1532 property() as a decorator to produce a read-only property.
1533
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001534- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1535 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1536 of requiring an int or long in slicing and a few other contexts, enabling
1537 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1538
Neal Norwitz995acdf2006-03-07 05:01:00 +00001539- Fixed various bugs reported by Coverity's Prevent tool.
1540
Brett Cannonbf364092006-03-01 04:25:17 +00001541- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1542 new exception base class, BaseException, which has a new message attribute.
1543 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1544 Raising a string exception now raises a DeprecationWarning.
1545
Thomas Woutersfb609f42006-02-28 16:37:25 +00001546- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1547 explicitly relative, using 'from .module import name' to mean 'from the same
1548 package as this module is in. Imports without dots still default to the
1549 old relative-then-absolute, unless 'from __future__ import
1550 absolute_import' is used.
1551
Brett Cannona7446e32006-02-27 23:39:10 +00001552- Properly check if 'warnings' raises an exception (usually when a filter set
1553 to "error" is triggered) when raising a warning for raising string
1554 exceptions.
1555
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001556- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001557 The name was removed from Include/code.h.
1558
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001559- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001560
Guido van Rossum1968ad32006-02-25 22:38:04 +00001561- Patch 1433928:
1562 - The copy module now "copies" function objects (as atomic objects).
1563 - dict.__getitem__ now looks for a __missing__ hook before raising
1564 KeyError.
1565
Tim Peters84ef21c2006-02-28 20:39:06 +00001566- PEP 343: with statement implemented. Needs ``from __future__ import
1567 with_statement``. Use of 'with' as a variable will generate a warning.
1568 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001569 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001570 The following objects have __context__ methods:
1571 - The built-in file type.
1572 - The thread.LockType type.
1573 - The following types defined by the threading module:
1574 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1575 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001576
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001577- Fix the encodings package codec search function to only search
1578 inside its own package. Fixes problem reported in patch #1433198.
1579
1580 Note: Codec packages should implement and register their own
1581 codec search function. PEP 100 has the details.
1582
Tim Peters9ea89d22006-06-04 03:26:02 +00001583- PEP 353: Using ``Py_ssize_t`` as the index type.
1584
1585- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1586 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1587 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1588 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1589 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001590
Neal Norwitzfc76d632006-01-10 06:03:13 +00001591- Patch #1400181, fix unicode string formatting to not use the locale.
1592 This is how string objects work. u'%f' could use , instead of .
1593 for the decimal point. Now both strings and unicode always use periods.
1594
Neal Norwitz671b9e32006-01-09 07:07:12 +00001595- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1596 configure would break checking curses.h.
1597
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001598- Bug #959576: The pwd module is now builtin. This allows Python to be
1599 built on UNIX platforms without $HOME set.
1600
Neal Norwitzc10978f2005-12-19 06:07:16 +00001601- Bug #1072182, fix some potential problems if characters are signed.
1602
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001603- Bug #889500, fix line number on SyntaxWarning for global declarations.
1604
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001605- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1606
Neal Norwitze7214a12005-12-18 05:03:17 +00001607- Support for converting hex strings to floats no longer works.
1608 This was not portable. float('0x3') now raises a ValueError.
1609
Barry Warsaw2a38a862005-12-18 01:27:35 +00001610- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001611 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001612 is now displayed in interactive prompt banner.
1613
Georg Brandlfa166682005-12-17 21:45:17 +00001614- Implementation of PEP 341 - Unification of try/except and try/finally.
1615 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001616 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001617
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001618- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1619 now encodes backslash correctly.
1620
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001621- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1622
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001623- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001624 and long longs.
1625
Neal Norwitz67715f02005-11-09 06:59:35 +00001626- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001627 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001628 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001629
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001630- Replaced most Unicode charmap codecs with new ones using the
1631 new Unicode translate string feature in the builtin charmap
1632 codec; the codecs were created from the mapping tables available
1633 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1634 encodings now include a mapping for the Apple logo)
1635
Tim Peterse3547fd2005-12-16 23:13:57 +00001636- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001637
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001638- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001639
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001640- A new AST parser implementation was completed. The abstract
1641 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001642 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001643
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001644- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001645 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1646
Neal Norwitz708e51a2005-10-03 04:48:15 +00001647- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1648
Neal Norwitz11bd1192005-10-03 00:54:56 +00001649- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1650 Provide a warning when a directory is passed on the command line.
1651
Neal Norwitz40d37812005-10-02 01:48:49 +00001652- Fix segfault with invalid coding.
1653
1654- SF bug #772896: unknown encoding results in MemoryError.
1655
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001656- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001657 supported a __len__() method which evaluated to False when the iterator
1658 was empty.
1659
Guido van Rossum630db602005-09-20 18:49:54 +00001660- On 64-bit platforms, when __len__() returns a value that cannot be
1661 represented as a C int, raise OverflowError.
1662
Skip Montanarof8948ca2005-09-19 03:54:46 +00001663- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001664 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001665
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001666- SF bug #893549: parsing keyword arguments was broken with a few format
1667 codes.
1668
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001669- Changes donated by Elemental Security to make it work on AIX 5.3
1670 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1671 bug #105470: test_pwd fails on 64bit system (Opteron).
1672
Guido van Rossum539c6622005-09-14 17:49:54 +00001673- Changes donated by Elemental Security to make it work on HP-UX 11 on
1674 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1675
Georg Brandl4550b8d2005-08-26 06:43:52 +00001676- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001677 (fixes bug #1119418).
1678
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001679- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1680
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001681- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1682 exceptions that cause a function to exit.
1683
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001684- The implementation of set() and frozenset() was revised to use its
1685 own internal data structure. Memory consumption is reduced by 1/3
1686 and there are modest speed-ups as well. The API is unchanged.
1687
Tim Petersde7990b2005-07-17 23:45:23 +00001688- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1689
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001690- SF bug #1229429: PyObject_CallMethod failed to decrement some
1691 reference counts in some error exit cases.
1692
Tim Petersecc6e6a2005-07-10 22:30:55 +00001693- SF bug #1185883: Python's small-object memory allocator took over
1694 a block managed by the platform C library whenever a realloc specified
1695 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001696 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001697 portable way to copy data from the C-managed block into Python's
1698 small-object space without risking a memory fault. Python's small-object
1699 realloc now leaves such blocks under the control of the platform C
1700 realloc.
1701
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001702- SF bug #1232517: An overflow error was not detected properly when
1703 attempting to convert a large float to an int in os.utime().
1704
Raymond Hettinger3296e692005-06-29 23:29:56 +00001705- SF bug #1224347: hex longs now print with lowercase letters just
1706 like their int counterparts.
1707
Michael W. Hudson188d4362005-06-20 16:52:57 +00001708- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1709 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1710 interpreter states; back out that fix and do a better job (see
1711 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1712 for a longer write-up of the problem).
1713
Michael W. Hudsondf888462005-06-03 14:41:55 +00001714- SF patch #1180995: marshal now uses a binary format by default when
1715 serializing floats.
1716
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001717- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1718 the routines that promise to produce IEEE 754 binary representations
1719 of floats now simply copy bytes around.
1720
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001721- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1722 278.
1723
Brett Cannonc3647ac2005-04-26 03:45:26 +00001724- patch #1109424: int, long, float, complex, and unicode now check for the
1725 proper magic slot for type conversions when subclassed. Previously the
1726 magic slot was ignored during conversion. Semantics now match the way
1727 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001728 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001729 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001730 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001731
Barry Warsawc8d907c2005-04-19 23:43:40 +00001732- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1733 NULL, now raise an AttributeError when attempting to set or delete the
1734 attribute. Previously a TypeError was raised, but this was inconsistent
1735 with the equivalent pure-Python implementation.
1736
Michael W. Hudson774479c2005-04-18 08:46:17 +00001737- It is now safe to call PyGILState_Release() before
1738 PyEval_InitThreads() (note that if there is reason to believe there
1739 are multiple threads around you still must call PyEval_InitThreads()
1740 before using the Python API; this fix is for extension modules that
1741 have no way of knowing if Python is multi-threaded yet).
1742
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001743- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1744 disabled caused a crash.
1745
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001746- Bug #1165306: instancemethod_new allowed the creation of a method
1747 with im_class == im_self == NULL, which caused a crash when called.
1748
Tim Petersecc6e6a2005-07-10 22:30:55 +00001749- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001750 fixes the crash seen in bug #1165761
1751
Raymond Hettinger96229b12005-03-11 06:49:40 +00001752- Added two new builtins, any() and all().
1753
Brett Cannon409d8f22005-03-05 06:47:57 +00001754- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001755 (e.g., ``class C(): pass`` is no longer a syntax error).
1756 Patch #1176012 added support to the 'parser' module and 'compiler' package
1757 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001758
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001759- Patch #1115086: Support PY_LONGLONG in structmember.
1760
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001761- Bug #1155938: new style classes did not check that __init__() was
1762 returning None.
1763
Tim Petersecc6e6a2005-07-10 22:30:55 +00001764- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001765 ('\') with a specific error message.
1766
Martin v. Löwisff232d72005-03-03 09:24:38 +00001767- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1768
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001769- Bug #1124295: the __name__ attribute of file objects was
1770 inadvertently made inaccessible in restricted mode.

1791 unicode instance if the argument is not an instance of basestring and
1792 calling __str__ on the argument returns a unicode instance.
1793
Tim Petersf4e69282006-02-27 17:15:31 +00001794- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1795 current thread state when the auto-GIL-state machinery knows about
1796 it (since the thread state is being deleted, continuing to remember it
1797 can't help, but can hurt if another thread happens to get created with
1798 the same thread id).

2006 in attribute values.
2007
Anthony Baxterc51ee692006-04-01 00:57:31 +00002008- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002009 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002010 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002011 module will not be built.

Tim Petersc17976e2006-04-01 00:26:53 +00002013- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2014 aren't officially supported here, and trying to use them will probably

2038 package that was included in Python 2.3, except that PEP 8 module names are
2039 now used (e.g. mail.message instead of email.Message). The MIME classes
2040 have been moved to a subpackage (e.g. email.mime.text instead of
2041 email.MIMEText). The old names are still supported for now. Several
2042 deprecated Message methods have been removed and lots of bugs have been
2043 fixed. More details can be found in the email package documentation.

2046 (a subclass of tuple) that provides incremental decoders and encoders
2047 (a way to use stateful codecs without the stream API). Python functions
2048 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2049 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2050 have been added.

2131 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2132 Ronald L. Rivest offered this advice for Python:
2133
2134 "The consensus of researchers in this area (at least as
2135 expressed at the NIST Hash Function Workshop 10/31/05),
2136 is that SHA-256 is a good choice for the time being, but
2137 that research should continue, and other alternatives may
2138 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002139

Guido van Rossumd0641422005-02-03 15:01:24 +00002299- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2300 disables recursive traversal through instance attributes, which can
2301 be exploited in various ways.
2302
Tim Peterse3547fd2005-12-16 23:13:57 +00002303- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002304 flags on the HTTP listening socket.
2305
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002306- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2307 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2308
Fred Drakefbdeaad2006-07-29 16:56:15 +00002309- Patches #893642, #1039083: add allow_none, encoding arguments to
2310 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002311
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002312- Bug #1110478: Revert os.environ.update to do putenv again.
2313
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002314- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2315
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002316- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2317
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002318- Enhancements to the csv module:
2319
2320 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002321 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002322 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002323 + Dialect parameter parsing has been re-implemented to improve error
2324 reporting.
2325 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2326 dictates.
2327 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002328 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002329 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002330 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2331 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002332 + reader now allows \r characters to be quoted (previously it only allowed
2333 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002334 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002335 + Dialect classes passed to the module are no longer instantiated by
2336 the module before being parsed (the former validation scheme required
2337 this, but the mechanism was unreliable).
2338 + The dialect registry now contains instances of the internal
2339 C-coded dialect type, rather than references to python objects.
2340 + the internal c-coded dialect type is now immutable.
2341 + register_dialect now accepts the same keyword dialect specifications
2342 as the reader and writer, allowing the user to register dialects
2343 without first creating a dialect class.
2344 + a configurable limit to the size of parsed fields has been added -
2345 previously, an unmatched quote character could result in the entire
2346 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002347 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002348 the parser field size limit (returning the former limit). The initial
2349 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002350 + A line_num attribute has been added to the reader object, which tracks
2351 the number of lines read from the source iterator. This is not
2352 the same as the number of records returned, as records can span
2353 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002354 + reader and writer objects were not being registered with the cyclic-GC.
2355 This has been fixed.
2356
Brett Cannone6539c42005-01-08 02:43:53 +00002357- _DummyThread objects in the threading module now delete self.__block that is
2358 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2359 lock primitives tend to be limited in number and thus should not be wasted on
2360 a _DummyThread object. Fixes bug #1089632.
2361
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002362- The imghdr module now detects Exif files.
2363
Raymond Hettinger6065d322004-12-20 23:51:53 +00002364- StringIO.truncate() now correctly adjusts the size attribute.
2365 (Bug #951915).
2366
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002367- locale.py now uses an updated locale alias table (built using
2368 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2369 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002370 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002371
Raymond Hettinger3557f422004-12-07 12:02:02 +00002372- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2373
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002374- the pickle module no longer accepts the deprecated None option in the
2375 args tuple returned by __reduce__().
2376
Brett Cannon84667c02004-12-07 03:25:18 +00002377- optparse now optionally imports gettext. This allows its use in setup.py.
2378
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002379- the pickle module no longer uses the deprecated bin parameter.
2380
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002381- the shelve module no longer uses the deprecated binary parameter.
2382
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002383- the pstats module no longer uses the deprecated ignore() method.
2384
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002385- the filecmp module no longer uses the deprecated use_statcache argument.
2386
Raymond Hettinger664347b2004-12-04 21:21:53 +00002387- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2388 extended or overridden by subclasses. Formerly, the subclassed method would
2389 be ignored by the rest of the module. (Bug #1078905).
2390
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002391- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002392 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002393
Walter Dörwald36733692004-12-22 12:50:50 +00002394- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2395 once when a size argument is given. This prevents a buffer overflow in the
2396 tokenizer with very long source lines.
2397
Barry Warsaw538561e2006-01-01 21:48:54 +00002398- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2399 immediately after creating the object, without any intervening
2400 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002401
Skip Montanaro05885812005-01-16 20:48:27 +00002402- The reconvert.quote function can now emit triple-quoted strings. The
2403 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002404
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002405- ``UserString.MutableString`` now supports negative indices in
2406 ``__setitem__`` and ``__delitem__``
2407
Greg Ward40407942005-03-05 02:53:17 +00002408- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2409 correctly.
2410
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002411- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2412 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2413 character even if the user has passed a size parameter to get a proper
2414 line ending. Remove the special handling of a "\r\n" that has been split
2415 between two lines.
2416
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002417- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2418 about illegal code points. The codec now supports PEP 293 style error
2419 handlers.
2420
Walter Dörwald78a78b02005-09-01 12:04:29 +00002421- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002422 from the input stream, so that the output is a byte string in the correct
2423 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002424
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002425- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2426 considering it exactly like a '*'.
2427
Walter Dörwald007f8df2005-10-09 19:42:27 +00002428- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2429 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002430
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002431- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2432
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002433- Patch #1413711: Certain patterns of differences were making difflib
2434 touch the recursion limit.
2435
Walter Dörwald58917a62006-03-31 15:26:22 +00002436- Bug #947906: An object oriented interface has been added to the calendar
2437 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002438 called as a script (e.g. via ``python -mcalendar``). Localized month and
2439 weekday names can be ouput (even if an exotic encoding is used) using
2440 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002441
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002442Build
2443-----
2444
Neal Norwitz602d3392006-03-31 08:21:40 +00002445- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2446 by using -mieee gcc option.
2447

2449
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002450- Build support for Win64-AMD64 was added.
2451
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002452- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2453
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002454- Patch #881820: look for openpty and forkpty also in libbsd.
2455
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002456- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2457 The zlib module is now builtin on Windows.
2458
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002459- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2460
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002461- Bug #1189330: configure did not correctly determine the necessary
2462 value of LINKCC if python was built with GCC 4.0.
2463
Trent Mick8321b422005-07-26 02:29:21 +00002464- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2465 vulnerability in zlib 1.2.1 and 1.2.2.
2466
Brett Cannon08cd5982005-04-24 22:26:38 +00002467- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2468 flags that change binary compatibility. Changes were also made to
2469 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002470 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002471
Bob Ippolitoed233462005-03-29 13:47:59 +00002472- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2473 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2474 no longer exists). This configure patch makes things right.
2475
Martin v. Löwise2713be2005-03-08 15:03:08 +00002476- Bug #1158607: Build with --disable-unicode again.
2477
Brett Cannon46d96232005-02-16 00:07:19 +00002478- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2479 defined. Discovered as a result of not being able to build on OS X.
2480
Brett Cannon516592f2004-12-07 00:42:59 +00002481- setup.py now uses the directories specified in LDFLAGS using the -L option
2482 and in CPPFLAGS using the -I option for adding library and include
2483 directories, respectively, for compiling extension modules against. This has
2484 led to the core being compiled using the values in CPPFLAGS. It also removes
2485 the need for the special-casing of both DarwinPorts and Fink for darwin since
2486 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2487 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2488 Fink, ``-I/opt/local/include`` for DarwinPorts).
2489
Brett Cannon43802422005-02-10 20:48:03 +00002490- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2491 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2492 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2493 Closes bug #1096244. Thanks Gregory Bond.
2494
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002495C API
2496-----
2497
Tim Petersc9d78aa2006-03-26 23:27:58 +00002498- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2499 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2500 is obtained via the ``PyObject_`` family, it must be released via the
2501 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2502 always been officially true, but when Python's small-object allocator was
2503 introduced, an attempt was made to cater to a few extension modules
2504 discovered at the time that obtained memory via ``PyObject_New`` but
2505 released it via ``PyMem_DEL``. It's years later, and if such code still
2506 exists it will fail now (probably with segfaults, but calling wrong
2507 low-level memory management functions can yield many symptoms).
2508
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002509- Added a C API for set and frozenset objects.
2510
Raymond Hettinger66517482004-12-03 11:45:13 +00002511- Removed PyRange_New().
2512
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002513- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2514 mapping argument now. This string is used as a mapping table. Byte values
2515 greater than the length of the string and 0xFFFE are treated as undefined
2516 mappings.
