334-----------------
335
Neal Norwitz0bcafac2006-09-11 08:51:17 +0000336- Make _PyGILState_NoteThreadState() static, it was not used anywhere
337 outside of pystate.c and should not be necessary.
338
Brett Cannon19d76c52006-09-09 07:18:44 +0000339- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
340 allows calling unicode() on exceptions classes directly to succeed.
341
Georg Brandlecab6232006-09-06 06:47:02 +0000342- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000357- The return tuple from str.rpartition(sep) is (tail, sep, head) where
358 head is the original string if sep was not found.
359
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000360- Bug #1520864: unpacking singleton tuples in list comprehensions and
361 generator expressions (x for x, in ... ) works again. Fixing this problem
362 required changing the .pyc magic number. This means that .pyc files
363 generated before 2.5c2 will be regenerated.

466Core and builtins
467-----------------
468
Neal Norwitz24b6f202006-09-05 04:43:56 +0000469- Fix infinite recursion when subclassing long and overriding __hash__.
470
471- Fix concatenation (+=) of long strings.
472
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000473- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000474 compared equal or unequal to a string and a UnicodeDecodeError
475 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000476
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000477 Instead, the equal (==) and unequal (!=) comparison operators will
478 now issue a UnicodeWarning and interpret the two objects as
479 unequal. The UnicodeWarning can be filtered as desired using
480 the warning framework, e.g. silenced completely, turned into an
481 exception, logged, etc.
482
483 Note that compare operators other than equal and unequal will still
484 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000485
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000486- Fix segfault when doing string formatting on subclasses of long.
487
488- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
489 with new-style classes.
490
491- Fix bug related to __len__ functions returning negative values with
492 classic classes.
493
494- Patch #1538606, Fix __index__() clipping. There were some problems
495 discovered with the API and how integers that didn't fit into Py_ssize_t
496 were handled. This patch attempts to provide enough alternatives
497 to effectively use __index__.
498
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000499- Bug #1536021: __hash__ may now return long int; the final hash
500 value is obtained by invoking hash on the long int.
501
Thomas Hellerab1049c2006-08-08 17:37:00 +0000502- Bug #1536786: buffer comparison could emit a RuntimeWarning.

Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000504- Bug #1535165: fixed a segfault in input() and raw_input() when
505 sys.stdin is closed.
506
Thomas Heller74d36f02006-08-04 18:17:40 +0000507- On Windows, the PyErr_Warn function is now exported from
508 the Python dll again.
509
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000510- Bug #1191458: tracing over for loops now produces a line event
511 on each iteration. Fixing this problem required changing the .pyc
512 magic number. This means that .pyc files generated before 2.5c1
513 will be regenerated.
514
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000515- Bug #1333982: string/number constants were inappropriately stored
516 in the byte code and co_consts even if they were not used, ie
517 immediately popped off the stack.
518
Georg Brandle9462c72006-08-04 18:03:37 +0000519- Fixed a reference-counting problem in property().

522Library
523-------
524
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000525- Fix a bug in the ``compiler`` package that caused invalid code to be
526 generated for generator expressions.
527
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000528- The distutils version has been changed to 2.5.0. The change to
529 keep it programmatically in sync with the Python version running
530 the code (introduced in 2.5b3) has been reverted. It will continue
531 to be maintained manually as static string literal.
532
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000533- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000534 and this cannot be converted to the required C type, an exception is
535 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000536 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000537
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000538- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000539 an exception.
540
Tim Peterscbdd3502006-09-05 01:47:53 +0000541- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000542 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000543 workarounds for clocks with low resolution, to stop the code yielding
544 duplicate UUIDs.
545
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000546- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
547 before raising SystemExit, allowing IDLE to honor quit() and exit().
548
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000549- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
550
Georg Brandl7a1af772006-08-14 21:55:28 +0000551- Patch #1536071: trace.py should now find the full module name of a
552 file correctly even on Windows.
553
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000554- logging's atexit hook now runs even if the rest of the module has
555 already been cleaned up.
556
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000557- Bug #1112549, fix DoS attack on cgi.FieldStorage.

560 str(exception) raised an exception.
561
Neil Schemenauer06ded092006-08-04 16:20:30 +0000562- Fix a bug in the ``compiler`` package that caused invalid code to be
563 generated for nested functions.

575
Thomas Heller1ce433e2006-08-14 16:20:04 +0000576- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
577 '-no-stack-protector' compiler flag for OpenBSD has been removed.
578
Thomas Heller86720042006-08-14 11:17:48 +0000579- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
580 uses the _as_parameter_ attribute when objects are passed to foreign
581 function calls. The ctypes version number was changed to 1.0.1.
582
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000583- Bug #1530559, struct.pack raises TypeError where it used to convert.
584 Passing float arguments to struct.pack when integers are expected
585 now triggers a DeprecationWarning.

Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000622- New API for Unicode rich comparisons: PyUnicode_RichCompare()
623
Tim Peters4643c2f2006-08-10 22:45:34 +0000624- Bug #1069160. Internal correctness changes were made to
625 ``PyThreadState_SetAsyncExc()``. A test case was added, and
626 the documentation was changed to state that the return value
627 is always 1 (normal) or 0 (if the specified thread wasn't found).

631================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000632
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000633*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000634
635Core and builtins
636-----------------
637
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000638- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000639 returned a long (see PEP 353).
640
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000641- Bug #1515471: string.replace() accepts character buffers again.
642
Neal Norwitz07aadb12006-07-30 06:55:48 +0000643- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
644 This provides the proper warning for struct.pack().
645 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
646
Neal Norwitz0d62a062006-07-30 06:53:31 +0000647- Patch #1531113: Fix augmented assignment with yield expressions.
648 Also fix a SystemError when trying to assign to yield expressions.
649
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000650- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
651 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
652 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
653 excessive filesystem operations during imports.
654
Tim Petersbc24eee2006-07-27 01:14:53 +0000655- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
656 operations on signed longs that are formally undefined by C.
657 Unfortunately, at least one compiler now cares about that, so complicated
658 the code to make that compiler happy again.
659
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000660- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
661
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000662- Patch #1232023: Stop including current directory in search
663 path on Windows.
664
Neal Norwitze1fdb322006-07-21 05:32:28 +0000665- Fix some potential crashes found with failmalloc.
666
Neal Norwitze7563102006-07-17 01:00:16 +0000667- Fix warnings reported by Klocwork's static analysis tool.
668
Neal Norwitz84be93b2006-07-16 01:50:38 +0000669- Bug #1512814, Fix incorrect lineno's when code within a function
670 had more than 255 blank lines.
671
Georg Brandl9dceedb2006-07-12 15:31:17 +0000672- Patch #1521179: Python now accepts the standard options ``--help`` and
673 ``--version`` as well as ``/?`` on Windows.
674
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000675- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000676 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000677 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000678
Tim Peters112aad32006-07-19 00:03:19 +0000679- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000680 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000681 new ``sys._current_frames()`` returns a dictionary with one entry,
682 mapping the faux "thread id" 0 to the current frame.
683
Ronald Oussoren3075e162006-07-25 20:28:55 +0000684- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000685
Ronald Oussoren3075e162006-07-25 20:28:55 +0000686
Neal Norwitza1f10902006-07-12 07:28:29 +0000687Library
688-------
689
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000690- Correction of patch #1455898: In the mbcs decoder, set final=False
691 for stream decoder, but final=True for the decode function.
692
Georg Brandl07fec3a2006-08-01 18:49:24 +0000693- os.urandom no longer masks unrelated exceptions like SystemExit or
694 KeyboardInterrupt.
695
Tim Peters4643c2f2006-08-10 22:45:34 +0000696- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000697 shutil.copytree on Windows
698
Georg Brandle34ac7c2006-07-30 11:07:23 +0000699- Bug #1002398: The documentation for os.path.sameopenfile now correctly
700 refers to file descriptors, not file objects.
701
Tim Peterscbdd3502006-09-05 01:47:53 +0000702- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000703 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000704 #1513611, and probably others.
705
Georg Brandledd9b0d2006-07-29 09:33:26 +0000706- Bug #1441397: The compiler module now recognizes module and function
707 docstrings correctly as it did in Python 2.4.
708
Tim Peters6f681472006-07-27 23:44:37 +0000709- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
710 lost that tests are sorted by name before being run. This rarely
711 matters for well-written tests, but can create baffling symptoms if
712 side effects from one test to the next affect outcomes. ``DocTestFinder``
713 has been changed to sort the list of tests it returns.
714
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000715- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000716 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000717
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000718- Bug #978833: Really close underlying socket in _socketobject.close.
719
Georg Brandldb232dc2006-08-20 13:15:43 +0000720- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
721 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000722
Georg Brandlcf0c1722006-07-26 07:23:32 +0000723- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
724 to recursive calls and call it with the failing package name.
725
Martin v. Löwis0b483032006-07-25 09:53:12 +0000726- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
727
Georg Brandlc13c34c2006-07-24 14:09:56 +0000728- Patch #1515343: Fix printing of deprecated string exceptions with a
729 value in the traceback module.
730
Greg Ward48fae7a2006-07-23 16:05:51 +0000731- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
732
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000733- Patch #1524429: Use repr() instead of backticks in Tkinter again.
734
Brett Cannoncaebe222006-07-18 04:41:36 +0000735- Bug #1520914: Change time.strftime() to accept a zero for any position in its
736 argument tuple. For arguments where zero is illegal, the value is forced to
737 the minimum value that is correct. This is to support an undocumented but
738 common way people used to fill in inconsequential information in the time
739 tuple pre-2.4.
740
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000741- Patch #1220874: Update the binhex module for Mach-O.
742
Barry Warsawb110bad2006-07-21 14:51:07 +0000743- The email package has improved RFC 2231 support, specifically for
744 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
745 (name*0=<blah>) parameter continuations. This may change the types of
746 values returned from email.message.Message.get_param() and friends.
747 Specifically in some cases where non-encoded continuations were used,
748 get_param() used to return a 3-tuple of (None, None, string) whereas now it
749 will just return the string (since non-encoded continuations don't have
750 charset and language parts).
751
752 Also, whereas % values were decoded in all parameter continuations, they are
753 now only decoded in encoded parameter parts.
754
Ronald Oussoren3075e162006-07-25 20:28:55 +0000755- Bug #1517990: IDLE keybindings on MacOS X now work correctly
756
757- Bug #1517996: IDLE now longer shows the default Tk menu when a
758 path browser, class browser or debugger is the frontmost window on MacOS X
759
Barry Warsaw00decd72006-07-27 23:43:15 +0000760- Patch #1520294: Support for getset and member descriptors in types.py,
761 inspect.py, and pydoc.py. Specifically, this allows for querying the type
762 of an object against these built-in types and more importantly, for getting
763 their docstrings printed in the interactive interpreter's help() function.
764
Ronald Oussoren3075e162006-07-25 20:28:55 +0000765
Neal Norwitza1f10902006-07-12 07:28:29 +0000766Extension Modules
767-----------------
768
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000769- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
770 a socket operation on a socket with a timeout, the exception will be
771 caught correctly. Previously, the exception was not caught.
772
Thomas Heller1393d6a2006-07-28 21:43:20 +0000773- Patch #1529514: The _ctypes extension is now compiled on more
774 openbsd target platforms.
775
Tim Peters9cab5932006-07-28 00:30:00 +0000776- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
777 a memory leak, affecting pickles and deep copies.
778
Tim Petersbc24eee2006-07-27 01:14:53 +0000779- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000780 Paul Eggert.
781
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000782- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
783
Thomas Hellerce049a02006-07-14 17:51:14 +0000784- Patch #1521817: Index range checking on ctypes arrays containing
785 exactly one element enabled again. This allows iterating over these
786 arrays, without the need to check the array size before.
787
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000788- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000789 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000790 /dev/null in certain cases; this is now fixed.
791
Thomas Heller47d7a062006-07-12 08:43:47 +0000792- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
793 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000794
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000795- Because of a misspelled preprocessor symbol, ctypes was always
796 compiled without thread support; this is now fixed.
797
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000798- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
799 methods now allow their database parameter to be None as the
800 sleepycat API allows.
801
Matt Flemingec926502006-07-28 11:27:27 +0000802- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
803 bluetooth API compared with Linux and FreeBSD.
804
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000805Tests
806-----
807
808- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
809 how long the test file should take to play. Now accepts taking 2.93 secs
810 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
811
Georg Brandl4793aa32006-07-28 18:31:39 +0000812- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
813 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
814 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +0000815
Martin v. Löwis0907f4d2006-07-30 14:09:47 +0000816Build
817-----
818
819- Bug #1439538: Drop usage of test -e in configure as it is not portable.
820
Ronald Oussoren26cad082006-08-01 21:00:57 +0000821Mac
822---
823
824- PythonLauncher now works correctly when the path to the script contains
825 characters that are treated specially by the shell (such as quotes).
826
827- Bug #1527397: PythonLauncher now launches scripts with the working directory
828 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000829 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000830 expect.

838Core and builtins
839-----------------
840
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000841- Bug #1441486: The literal representation of -(sys.maxint - 1)
842 again evaluates to a int object, not a long.
843
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000844- Bug #1501934: The scope of global variables that are locally assigned
845 using augmented assignment is now correctly determined.
846
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000847- Bug #927248: Recursive method-wrapper objects can now safely
848 be released.
849
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000850- Bug #1417699: Reject locale-specific decimal point in float()
851 and atof().
852
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000853- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
854 omit a default "error" argument for NULL pointer. This allows
855 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000856
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000857- Bug #1519018: 'as' is now validated properly in import statements.
858
Neal Norwitz28746ab2006-07-09 22:14:42 +0000859- On 64 bit systems, int literals that use less than 64 bits are
860 now ints rather than longs.
861
Neal Norwitzed657552006-07-10 00:04:44 +0000862- Bug #1512814, Fix incorrect lineno's when code at module scope
863 started after line 256.
864
Tim Peters32a83612006-07-10 21:08:24 +0000865- New function ``sys._current_frames()`` returns a dict mapping thread
866 id to topmost thread stack frame. This is for expert use, and is
867 especially useful for debugging application deadlocks. The functionality
868 was previously available in Fazal Majid's ``threadframe`` extension
869 module, but it wasn't possible to do this in a wholly threadsafe way from
870 an extension.

873-------
874
Martin v. Löwis77621582006-07-30 13:27:31 +0000875- Bug #1257728: Mention Cygwin in distutils error message about a missing

879
Tim Peters32a83612006-07-10 21:08:24 +0000880- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000881 environment variable to be set in order to the SDK environment
882 for finding the compiler, include files, etc.
883
Martin v. Löwis388a8c22006-07-06 19:28:03 +0000884- Bug #1515998: Properly generate logical ids for files in bdist_msi.

Nick Coghlan2d792252006-07-06 13:47:18 +0000886- warnings.py now ignores ImportWarning by default
887
Thomas Woutersadd19112006-07-05 11:03:49 +0000888- string.Template() now correctly handles tuple-values. Previously,
889 multi-value tuples would raise an exception and single-value tuples would
890 be treated as the value they contain, instead.
891
Martin v. Löwisede77f52006-07-03 13:01:35 +0000892- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

899 degrees and radians.
900
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000901- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000902 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000903

905 is created.
906
Martin v. Löwis7596e832006-07-01 15:33:37 +0000907- Bug #1513223: .close() of a _socketobj now releases the underlying
908 socket again, which then gets closed as it becomes unreferenced.
909
Fred Drake10497c82006-06-29 02:57:48 +0000910- Bug #1504333: Make sgmllib support angle brackets in quoted
911 attribute values.
912
913- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
914 sgmllib ('[' and ']' were not accepted).
915
Georg Brandl1be63af2006-06-28 20:23:25 +0000916- Fix a bug in the turtle module's end_fill function.
917
Brett Cannon53ab5b72006-06-22 16:49:14 +0000918- Bug #1510580: The 'warnings' module improperly required that a Warning
919 category be either a types.ClassType and a subclass of Warning. The proper
920 check is just that it is a subclass with Warning as the documentation states.
921
Georg Brandlad29e632006-06-21 17:45:17 +0000922- The compiler module now correctly compiles the new try-except-finally
923 statement (bug #1509132).
924
Neal Norwitz60373cd2006-06-22 06:30:50 +0000925- The wsgiref package is now installed properly on Unix.
926
Vinay Sajip28e57612006-07-01 10:45:20 +0000927- A bug was fixed in logging.config.fileConfig() which caused a crash on
928 shutdown when fileConfig() was called multiple times.
929
Gerhard Häring762fbd32006-07-02 17:48:30 +0000930- The sqlite3 module did cut off data from the SQLite database at the first
931 null character before sending it to a custom converter. This has been fixed
932 now.
933

935-----------------
936
Tim Peters112aad32006-07-19 00:03:19 +0000937- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
938 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
939 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000940
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000941- Assigning None to pointer type fields in ctypes structures possible
942 overwrote the wrong fields, this is fixed now.
943
944- Fixed a segfault in _ctypes when ctypes.wintypes were imported
945 on non-Windows platforms.
946
947- Bug #1518190: The ctypes.c_void_p constructor now accepts any
948 integer or long, without range checking.
949
950- Patch #1517790: It is now possible to use custom objects in the ctypes
951 foreign function argtypes sequence as long as they provide a from_param
952 method, no longer is it required that the object is a ctypes type.
953
954- The '_ctypes' extension module now works when Python is configured
955 with the --without-threads option.
956
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000957- Bug #1513646: os.access on Windows now correctly determines write
958 access, again.
959
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000960- Bug #1512695: cPickle.loads could crash if it was interrupted with
961 a KeyboardInterrupt.
962
Neal Norwitza12aa882006-07-06 06:45:08 +0000963- Bug #1296433: parsing XML with a non-default encoding and
964 a CharacterDataHandler could crash the interpreter in pyexpat.
965
Neal Norwitz2a30cd02006-07-10 01:18:57 +0000966- Patch #1516912: improve Modules support for OpenVMS.

972
Tim Peters32a83612006-07-10 21:08:24 +0000973- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000974 Previously, the slight difference could cause compilation errors of the
975 'zlib' module on systems with more than one version of zlib.
976
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000977- The MSI compileall step was fixed to also support a TARGETDIR
978 with spaces in it.

981 of Tcl/Tk.
982
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000983- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000984 trying to be installed even though it's empty.

1008Core and builtins
1009-----------------
1010
Georg Brandla56b9152006-06-19 06:35:54 +00001011- Patch #1507676: Error messages returned by invalid abstract object operations
1012 (such as iterating over an integer) have been improved and now include the
1013 type of the offending object to help with debugging.
1014
Brett Cannonea3912b2006-06-13 21:46:41 +00001015- Bug #992017: A classic class that defined a __coerce__() method that returned
1016 its arguments swapped would infinitely recurse and segfault the interpreter.
1017
Neal Norwitz909eb122006-06-12 02:13:21 +00001018- Fix the socket tests so they can be run concurrently.
1019
Neal Norwitzb9845e72006-06-12 02:11:18 +00001020- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001021 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001022
Brett Cannon22565aa2006-06-09 22:31:23 +00001023- Bug #532646: object.__call__() will continue looking for the __call__
1024 attribute on objects until one without one is found. This leads to recursion
1025 when you take a class and set its __call__ attribute to an instance of the
1026 class. Originally fixed for classic classes, but this fix is for new-style.
1027 Removes the infinite_rec_3 crasher.
1028
Georg Brandl24250812006-06-09 18:45:48 +00001029- The string and unicode methods startswith() and endswith() now accept
1030 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1031
Brett Cannonde3b0522006-06-08 17:00:45 +00001032- Buffer objects, at the C level, never used the char buffer
1033 implementation even when the char buffer for the wrapped object was
1034 explicitly requested (originally returned the read or write buffer).
1035 Now a TypeError is raised if the char buffer is not present but is
1036 requested.
1037
Georg Brandlddbaa662006-06-04 21:56:52 +00001038- Patch #1346214: Statements like "if 0: suite" are now again optimized
1039 away like they were in Python 2.4.
1040
Georg Brandlb7c8f542006-05-27 12:30:25 +00001041- Builtin exceptions are now full-blown new-style classes instead of
1042 instances pretending to be classes, which speeds up exception handling
1043 by about 80% in comparison to 2.5a2.
1044
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001045- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1046 Unicode 4.1.
1047
Georg Brandlf4ef1162006-05-26 18:03:31 +00001048- Patch #921466: sys.path_importer_cache is now used to cache valid and
1049 invalid file paths for the built-in import machinery which leads to
1050 fewer open calls on startup.
1051
Tim Peters696cf432006-05-24 21:10:40 +00001052- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1053 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1054 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1055 the number of input digits (it was and remains linear-time for bases
1056 2, 4, 8, 16 and 32).
1057
Tim Petersb713ec22006-05-23 18:45:30 +00001058- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1059 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1060 an integer close to ``sys.maxint``. This was repaired by patch
1061 #1335972, which also gives a nice speedup.
1062
Richard Jonescebbefc2006-05-23 18:28:17 +00001063- Patch #1337051: reduced size of frame objects.
1064
1065- PyErr_NewException now accepts a tuple of base classes as its
1066 "base" parameter.
1067
Richard Jones7c88dcc2006-05-23 10:37:38 +00001068- Patch #876206: function call speedup by retaining allocated frame
1069 objects.
1070
Georg Brandl7b90e162006-05-18 07:01:27 +00001071- Bug #1462152: file() now checks more thoroughly for invalid mode
1072 strings and removes a possible "U" before passing the mode to the
1073 C library function.
1074
Neal Norwitz1004a532006-05-15 07:17:23 +00001075- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1076
Neal Norwitz373f0a72006-05-15 07:04:36 +00001077- Bug #1487966: Fix SystemError with conditional expression in assignment
1078
Martin v. Löwis879768d2006-05-11 13:28:43 +00001079- WindowsError now has two error code attributes: errno, which carries
1080 the error values from errno.h, and winerror, which carries the error
1081 values from winerror.h. Previous versions put the winerror.h values
1082 (from GetLastError()) into the errno attribute.
1083
Martin v. Löwis77736712006-05-04 05:51:03 +00001084- Patch #1475845: Raise IndentationError for unexpected indent.
1085
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001086- Patch #1479181: split open() and file() from being aliases for each other.
1087
Tim Peters44bd9862006-06-01 13:49:23 +00001088- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1089 methods were always silently ignored by dictionaries when comparing keys.
1090 They are now passed through (except when using the C API function
1091 ``PyDict_GetItem()``, whose semantics did not change).
1092
1093- Bug #1456209: In some obscure cases it was possible for a class with a
1094 custom ``__eq__()`` method to confuse dict internals when class instances
1095 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1096 No, you don't have any code that did this ;-)

1100
Trent Mick960a3f82006-06-28 20:30:41 +00001101- Bug #1295808: expat symbols should be namespaced in pyexpat
1102
1103- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1104
Brett Cannon6ee7d012006-06-08 16:23:04 +00001105- Change binascii.hexlify to accept a read-only buffer instead of only a char
1106 buffer and actually follow its documentation.
1107
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001108- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1109
Nick Coghlanc649ec52006-05-29 12:43:05 +00001110- Patch #1478788 (modified version): The functional extension module has
1111 been renamed to _functools and a functools Python wrapper module added.
1112 This provides a home for additional function related utilities that are
1113 not specifically about functional programming. See PEP 309.
1114
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001115- Patch #1493701: performance enhancements for struct module.

Georg Brandl8d3342b2006-05-16 07:38:27 +00001119- Patch #1435422: zlib's compress and decompress objects now have a
1120 copy() method.
1121
Andrew MacIntyre92913322006-06-13 15:04:24 +00001122- Patch #1454481: thread stack size is now tunable at runtime for thread
1123 enabled builds on Windows and systems with Posix threads support.
1124
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001125- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1126 (up to the system limit of 32K characters).
1127
1128- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1129 As a result, these functions now raise WindowsError instead of OSError.
1130
Tim Peters7a822da2006-05-25 21:50:17 +00001131- ``time.clock()`` on Win64 should use the high-performance Windows
1132 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1133 Windows platforms).
1134
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001135- Calling Tk_Init twice is refused if the first call failed as that
1136 may deadlock.
1137
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001138- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1139 accept it without potentially using an uninitialized pointer.
1140
1141- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1142 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1143 patch numbers 1494885 and 1494902]

1147
Gregory P. Smith372b5832006-06-05 18:48:21 +00001148- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1149 parameter is supplied. [SF pybsddb bug #1477863]
1150
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001151- bsddb: the __len__ method of a DB object has been fixed to return correct
1152 results. It could previously incorrectly return 0 in some cases.
1153 Fixes SF bug 1493322 (pybsddb bug 1184012).
1154
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001155- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1156 aborts the db transaction safely when a modifier callback fails.
1157 Fixes SF python patch/bug #1408584.
1158
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001159- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001160 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001161 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1162 database calls that would previously deadlock. [SF python bug #775414]
1163

1190
Martin v. Löwisd8251432006-06-14 05:21:04 +00001191- Patch #1455898: The MBCS codec now supports the incremental mode for
1192 double-byte encodings.
1193
Tim Peters43898b42006-06-14 04:09:25 +00001194- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1195 guarantee that adjacent triples in the return list always describe
1196 non-adjacent blocks. Previously, a pair of matching blocks could end
1197 up being described by multiple adjacent triples that formed a partition

Greg Ward0e0c9f42006-06-11 16:24:11 +00001200- Bug #1498146: fix optparse to handle Unicode strings in option help,
1201 description, and epilog.
1202
Greg Wardd1c797e2006-06-11 14:42:41 +00001203- Bug #1366250: minor optparse documentation error.
1204
Greg Ward7f547402006-06-11 00:40:49 +00001205- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1206 clarify docs.
1207
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001208- The wsgiref package has been added to the standard library.
1209
Nick Coghlan676725d2006-06-08 13:54:49 +00001210- The functions update_wrapper() and wraps() have been added to the functools
1211 module. These make it easier to copy relevant metadata from the original
1212 function when writing wrapper functions.
1213
Tim Petersd6a9eef2006-06-05 01:48:21 +00001214- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1215 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001216
Martin v. Löwis3f767792006-06-04 19:36:28 +00001217- Patch #1359618: Speed up charmap encoder by using a trie structure
1218 for lookup.
1219
Tim Petersd609b1a2006-06-02 23:22:51 +00001220- The functions in the ``pprint`` module now sort dictionaries by key
1221 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1222 if and only if its display required more than one line, although that
1223 wasn't documented. The new behavior increases predictability; e.g.,
1224 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1225
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001226- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1227 (thanks for J. J. Lee).
1228
Georg Brandl2b330372006-05-28 20:23:12 +00001229- Patch #1496206: improve urllib2 handling of passwords with respect to
1230 default HTTP and HTTPS ports.
1231
George Yoshidaf3c65de2006-05-28 16:39:09 +00001232- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1233
Bob Ippolito7298f272006-05-23 18:43:47 +00001234- Patch #1281707: speed up gzip.readline.
1235
Georg Brandlb89316f2006-05-17 15:51:16 +00001236- Patch #1180296: Two new functions were added to the locale module:
1237 format_string() to get the effect of "format % items" but locale-aware,
1238 and currency() to format a monetary number with currency sign.
1239
Georg Brandle3a25832006-05-17 14:56:04 +00001240- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1241 and several features added, such as speed and geometry control.
1242
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001243- Patch #1488881: add support for external file objects in bz2 compressed
1244 tarfiles.
1245
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001246- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1247 stdout arguments, making it possible to redirect input and output
1248 for remote debugging.
1249
1250- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1251 a couple of issues, notably handling of long file names using the
1252 GNU LONGNAME extension.
1253
1254- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1255 new flag when ``name`` is already the name of an option flag.
1256
1257- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1258 package.
1259
1260- Patch #1472854: make the rlcompleter.Completer class usable on non-
1261 UNIX platforms.
1262
1263- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1264
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001265- Bug #1472827: correctly escape newlines and tabs in attribute values in
1266 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001296What's New in Python 2.5 alpha 2?
1297=================================
1298
1299*Release date: 27-APR-2006*
1300
1301Core and builtins
1302-----------------
1303
Thomas Heller1b046642006-04-18 18:51:06 +00001304- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1305 by converting these apis from macros into exported functions again:
1306
1307 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1308 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1309 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1310 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1311 PyRun_String Py_CompileString
1312
Martin v. Löwis45294a92006-04-18 06:24:08 +00001313- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1314
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001315- All uses of PyStructSequence_InitType have been changed to initialize
1316 the type objects only once, even if the interpreter is initialized
1317 multiple times.
1318
Neal Norwitz61546162006-04-14 05:20:28 +00001319- Bug #1454485, array.array('u') could crash the interpreter. This was
1320 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1321 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1322
1323- Py_UNICODE is unsigned. It was always documented as unsigned, but
1324 due to a bug had a signed value in previous versions.
1325
Tim Peters3a5e8b12006-04-11 01:44:07 +00001326- Patch #837242: ``id()`` of any Python object always gives a positive
1327 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1328 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001329 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001330 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001331
Tim Peters3a5e8b12006-04-11 01:44:07 +00001332 def __hash__(self):
1333 return id(self) # WRONG
1334
1335 because a hash result must be a (short) Python int but it was always
1336 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001337 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001338 was always usable as a hash value before this patch. That's no longer
1339 necessarily so.
1340
1341- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001342 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001343 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001344 #1454844)
1345
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001346- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1347 involving generators that have paused outside of any ``try`` or ``with``
1348 blocks. (In 2.5a1, a paused generator that was part of a reference
1349 cycle could not be garbage collected, regardless of whether it was
1350 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001351
Anthony Baxter51bcb682006-04-05 14:51:42 +00001352Extension Modules

1354
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001355- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1356 is a macro.
1357
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001358- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1359 fails with an error condition.
1360
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001361- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1362
1363- Bug #1117761: bsddb.*open() no longer raises an exception when using
1364 the cachesize parameter.
1365
1366- Bug #1149413: bsddb.*open() no longer raises an exception when using
1367 a temporary db (file=None) with the 'n' flag to truncate on open.
1368
1369- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1370 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001371
Armin Rigoa9017c32006-04-19 11:50:27 +00001372- Patch #1062014: AF_UNIX sockets under Linux have a special
1373 abstract namespace that is now fully supported.

1377
Peter Astrand7d1d4362006-07-14 14:04:45 +00001378- Bug #1223937: subprocess.CalledProcessError reports the exit status
1379 of the process using the returncode attribute, instead of
1380 abusing errno.
1381
Tim Peters711bf302006-04-25 03:31:36 +00001382- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1383 a doctest to be skipped (the code is not run, and the expected output
1384 or exception is ignored).
1385
Nick Coghlanda2268f2006-04-24 04:37:15 +00001386- Fixed contextlib.nested to cope with exceptions being raised and
1387 caught inside exit handlers.
1388
Greg Wardab05edc2006-04-23 03:47:58 +00001389- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1390 hex, octal, or binary; add ``append_const`` action; keep going if
1391 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1392 added ``epilog`` for better help generation).
1393
Tim Peters21fbd572006-04-21 21:18:10 +00001394- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1395 called from a thread spawned as a side effect of importing a module.
1396
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001397- The pydoc module now supports documenting packages contained in
1398 .zip or .egg files.
1399
1400- The pkgutil module now has several new utility functions, such
1401 as ``walk_packages()`` to support working with packages that are either
1402 in the filesystem or zip files.
1403
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001404- The mailbox module can now modify and delete messages from
1405 mailboxes, in addition to simply reading them. Thanks to Gregory
1406 K. Johnson for writing the code, and to the 2005 Google Summer of
1407 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001408
Tim Petersc7605f22006-04-17 21:12:33 +00001409- The ``__del__`` method of class ``local`` in module ``_threading_local``
1410 returned before accomplishing any of its intended cleanup.
1411
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001412- Patch #790710: Add breakpoint command lists in pdb.
1413
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001414- Patch #1063914: Add Tkinter.Misc.clipboard_get().

1417
Anthony Baxtere29002c2006-04-12 12:07:31 +00001418- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1419 Windows. Bug #1469163.
1420
Phillip J. Eby47032112006-04-11 01:07:43 +00001421- The warnings, linecache, inspect, traceback, site, and doctest modules
1422 were updated to work correctly with modules imported from zipfiles or
1423 via other PEP 302 __loader__ objects.
1424
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001425- Patch #1467770: Reduce usage of subprocess._active to processes which
1426 the application hasn't waited on.

1436-----
1437
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001438- The Makefile now has a reindent target, which runs reindent.py on
1439 the library.
1440
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001441- Patch #1470875: Building Python with MS Free Compiler

1446 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001447 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001448 CXX from --with-cxx-main, see description in README.
1449
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001450- Patch #1429775: Link extension modules with the shared libpython.
1451
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001452- Fixed a libffi build problem on MIPS systems.
1453
Tim Peters8931ff12006-05-13 23:28:20 +00001454- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1455 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1456 and "%zu" for unsigned integers of type ``size_t``.
1457
Anthony Baxter51bcb682006-04-05 14:51:42 +00001458Tests
1459-----
1460
Nick Coghlanda2268f2006-04-24 04:37:15 +00001461- test_contextlib now checks contextlib.nested can cope with exceptions
1462 being raised and caught inside exit handlers.
1463
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001464- test_cmd_line now checks operation of the -m and -c command switches
1465
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001466- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1467 it separately and by hand. It also wasn't cleaning up its changes to
1468 the current Decimal context.
1469
Thomas Woutersabd08882006-04-26 15:53:30 +00001470- regrtest.py now has a -M option to run tests that test the new limits of
1471 containers, on 64-bit architectures. Running these tests is only sensible
1472 on 64-bit machines with more than two gigabytes of memory. The argument
1473 passed is the maximum amount of memory for the tests to use.

1485
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001486- PEP 343: Added Context Types section to the library reference
1487 and attempted to bring other PEP 343 related documentation into
1488 line with the implementation and/or python-dev discussions.
1489
Tim Peters8dc73d22006-04-24 02:03:16 +00001490- Bug #1337990: clarified that ``doctest`` does not support examples

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001494What's New in Python 2.5 alpha 1?
1495=================================
1496
Anthony Baxterebed3f62006-04-03 15:03:44 +00001497*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001498
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001499Core and builtins
1500-----------------
1501
Nick Coghlan43832302006-04-23 17:04:07 +00001502- PEP 338: -m command line switch now delegates to runpy.run_module
1503 allowing it to support modules in packages and zipfiles
1504
Martin v. Löwisc661b882006-04-20 04:54:23 +00001505- On Windows, .DLL is not an accepted file name extension for
1506 extension modules anymore; extensions are only found if they
1507 end in .PYD.
1508
Martin v. Löwisea62d252006-04-03 10:56:49 +00001509- Bug #1421664: sys.stderr.encoding is now set to the same value as
1510 sys.stdout.encoding.
1511
Neal Norwitz92e212f2006-04-03 04:48:37 +00001512- __import__ accepts keyword arguments.
1513
Georg Brandlccadf842006-03-31 18:54:53 +00001514- Patch #1460496: round() now accepts keyword arguments.
1515
Anthony Baxter262c00a2006-03-30 10:53:17 +00001516- Fixed bug #1459029 - unicode reprs were double-escaped.
1517
Hye-Shik Changd478f342006-03-23 12:32:36 +00001518- Patch #1396919: The system scope threads are reenabled on FreeBSD
1519 5.4 and later versions.
1520
Neal Norwitze98ccf62006-03-23 05:39:47 +00001521- Bug #1115379: Compiling a Unicode string with an encoding declaration
1522 now gives a SyntaxError.
1523
Georg Brandlabd1ff82006-03-18 07:59:59 +00001524- Previously, Python code had no easy way to access the contents of a
1525 cell object. Now, a ``cell_contents`` attribute has been added
1526 (closes patch #1170323).
1527
Tim Peterscf79aac2006-03-16 01:14:46 +00001528- Patch #1123430: Python's small-object allocator now returns an arena to
1529 the system ``free()`` when all memory within an arena becomes unused
1530 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1531 freed. Some applications will see a drop in virtual memory size now,
1532 especially long-running applications that, from time to time, temporarily
1533 use a large number of small objects. Note that when Python returns an
1534 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001535 platform C library will in turn return that memory to the operating system.
1536 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001537 appears to be effective at least on Microsoft C and gcc-based systems.
1538 Thanks to Evan Jones for hard work and patience.
1539
Georg Brandl533ff6f2006-03-08 18:09:27 +00001540- Patch #1434038: property() now uses the getter's docstring if there is
1541 no "doc" argument given. This makes it possible to legitimately use
1542 property() as a decorator to produce a read-only property.
1543
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001544- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1545 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1546 of requiring an int or long in slicing and a few other contexts, enabling
1547 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1548
Neal Norwitz995acdf2006-03-07 05:01:00 +00001549- Fixed various bugs reported by Coverity's Prevent tool.
1550
Brett Cannonbf364092006-03-01 04:25:17 +00001551- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1552 new exception base class, BaseException, which has a new message attribute.
1553 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1554 Raising a string exception now raises a DeprecationWarning.
1555
Thomas Woutersfb609f42006-02-28 16:37:25 +00001556- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1557 explicitly relative, using 'from .module import name' to mean 'from the same
1558 package as this module is in. Imports without dots still default to the
1559 old relative-then-absolute, unless 'from __future__ import
1560 absolute_import' is used.
1561
Brett Cannona7446e32006-02-27 23:39:10 +00001562- Properly check if 'warnings' raises an exception (usually when a filter set
1563 to "error" is triggered) when raising a warning for raising string
1564 exceptions.
1565
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001566- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001567 The name was removed from Include/code.h.
1568
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001569- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001570
Guido van Rossum1968ad32006-02-25 22:38:04 +00001571- Patch 1433928:
1572 - The copy module now "copies" function objects (as atomic objects).
1573 - dict.__getitem__ now looks for a __missing__ hook before raising
1574 KeyError.
1575
Tim Peters84ef21c2006-02-28 20:39:06 +00001576- PEP 343: with statement implemented. Needs ``from __future__ import
1577 with_statement``. Use of 'with' as a variable will generate a warning.
1578 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001579 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001580 The following objects have __context__ methods:
1581 - The built-in file type.
1582 - The thread.LockType type.
1583 - The following types defined by the threading module:
1584 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1585 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001586
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001587- Fix the encodings package codec search function to only search
1588 inside its own package. Fixes problem reported in patch #1433198.
1589
1590 Note: Codec packages should implement and register their own
1591 codec search function. PEP 100 has the details.
1592
Tim Peters9ea89d22006-06-04 03:26:02 +00001593- PEP 353: Using ``Py_ssize_t`` as the index type.
1594
1595- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1596 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1597 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1598 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1599 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001600
Neal Norwitzfc76d632006-01-10 06:03:13 +00001601- Patch #1400181, fix unicode string formatting to not use the locale.
1602 This is how string objects work. u'%f' could use , instead of .
1603 for the decimal point. Now both strings and unicode always use periods.
1604
Neal Norwitz671b9e32006-01-09 07:07:12 +00001605- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1606 configure would break checking curses.h.
1607
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001608- Bug #959576: The pwd module is now builtin. This allows Python to be
1609 built on UNIX platforms without $HOME set.
1610
Neal Norwitzc10978f2005-12-19 06:07:16 +00001611- Bug #1072182, fix some potential problems if characters are signed.
1612
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001613- Bug #889500, fix line number on SyntaxWarning for global declarations.
1614
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001615- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1616
Neal Norwitze7214a12005-12-18 05:03:17 +00001617- Support for converting hex strings to floats no longer works.
1618 This was not portable. float('0x3') now raises a ValueError.
1619
Barry Warsaw2a38a862005-12-18 01:27:35 +00001620- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001621 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001622 is now displayed in interactive prompt banner.
1623
Georg Brandlfa166682005-12-17 21:45:17 +00001624- Implementation of PEP 341 - Unification of try/except and try/finally.
1625 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001626 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001627
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001628- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1629 now encodes backslash correctly.
1630
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001631- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1632
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001633- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001634 and long longs.
1635
Neal Norwitz67715f02005-11-09 06:59:35 +00001636- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001637 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001638 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001639
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001640- Replaced most Unicode charmap codecs with new ones using the
1641 new Unicode translate string feature in the builtin charmap
1642 codec; the codecs were created from the mapping tables available
1643 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1644 encodings now include a mapping for the Apple logo)
1645
Tim Peterse3547fd2005-12-16 23:13:57 +00001646- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001647
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001648- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001649
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001650- A new AST parser implementation was completed. The abstract
1651 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001652 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001653
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001654- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001655 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1656
Neal Norwitz708e51a2005-10-03 04:48:15 +00001657- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1658
Neal Norwitz11bd1192005-10-03 00:54:56 +00001659- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1660 Provide a warning when a directory is passed on the command line.
1661
Neal Norwitz40d37812005-10-02 01:48:49 +00001662- Fix segfault with invalid coding.
1663
1664- SF bug #772896: unknown encoding results in MemoryError.
1665
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001666- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001667 supported a __len__() method which evaluated to False when the iterator
1668 was empty.
1669
Guido van Rossum630db602005-09-20 18:49:54 +00001670- On 64-bit platforms, when __len__() returns a value that cannot be
1671 represented as a C int, raise OverflowError.
1672
Skip Montanarof8948ca2005-09-19 03:54:46 +00001673- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001674 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001675
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001676- SF bug #893549: parsing keyword arguments was broken with a few format
1677 codes.
1678
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001679- Changes donated by Elemental Security to make it work on AIX 5.3
1680 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1681 bug #105470: test_pwd fails on 64bit system (Opteron).
1682
Guido van Rossum539c6622005-09-14 17:49:54 +00001683- Changes donated by Elemental Security to make it work on HP-UX 11 on
1684 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1685
Georg Brandl4550b8d2005-08-26 06:43:52 +00001686- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001687 (fixes bug #1119418).
1688
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001689- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1690
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001691- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1692 exceptions that cause a function to exit.
1693
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001694- The implementation of set() and frozenset() was revised to use its
1695 own internal data structure. Memory consumption is reduced by 1/3
1696 and there are modest speed-ups as well. The API is unchanged.
1697
Tim Petersde7990b2005-07-17 23:45:23 +00001698- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1699
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001700- SF bug #1229429: PyObject_CallMethod failed to decrement some
1701 reference counts in some error exit cases.
1702
Tim Petersecc6e6a2005-07-10 22:30:55 +00001703- SF bug #1185883: Python's small-object memory allocator took over
1704 a block managed by the platform C library whenever a realloc specified
1705 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001706 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001707 portable way to copy data from the C-managed block into Python's
1708 small-object space without risking a memory fault. Python's small-object
1709 realloc now leaves such blocks under the control of the platform C
1710 realloc.
1711
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001712- SF bug #1232517: An overflow error was not detected properly when
1713 attempting to convert a large float to an int in os.utime().
1714
Raymond Hettinger3296e692005-06-29 23:29:56 +00001715- SF bug #1224347: hex longs now print with lowercase letters just
1716 like their int counterparts.
1717
Michael W. Hudson188d4362005-06-20 16:52:57 +00001718- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1719 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1720 interpreter states; back out that fix and do a better job (see
1721 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1722 for a longer write-up of the problem).
1723
Michael W. Hudsondf888462005-06-03 14:41:55 +00001724- SF patch #1180995: marshal now uses a binary format by default when
1725 serializing floats.
1726
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001727- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1728 the routines that promise to produce IEEE 754 binary representations
1729 of floats now simply copy bytes around.
1730
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001731- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1732 278.
1733
Brett Cannonc3647ac2005-04-26 03:45:26 +00001734- patch #1109424: int, long, float, complex, and unicode now check for the
1735 proper magic slot for type conversions when subclassed. Previously the
1736 magic slot was ignored during conversion. Semantics now match the way
1737 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001738 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001739 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001740 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001741
Barry Warsawc8d907c2005-04-19 23:43:40 +00001742- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1743 NULL, now raise an AttributeError when attempting to set or delete the
1744 attribute. Previously a TypeError was raised, but this was inconsistent
1745 with the equivalent pure-Python implementation.
1746
Michael W. Hudson774479c2005-04-18 08:46:17 +00001747- It is now safe to call PyGILState_Release() before
1748 PyEval_InitThreads() (note that if there is reason to believe there
1749 are multiple threads around you still must call PyEval_InitThreads()
1750 before using the Python API; this fix is for extension modules that
1751 have no way of knowing if Python is multi-threaded yet).
1752
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001753- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1754 disabled caused a crash.
1755
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001756- Bug #1165306: instancemethod_new allowed the creation of a method
1757 with im_class == im_self == NULL, which caused a crash when called.
1758
Tim Petersecc6e6a2005-07-10 22:30:55 +00001759- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001760 fixes the crash seen in bug #1165761
1761
Raymond Hettinger96229b12005-03-11 06:49:40 +00001762- Added two new builtins, any() and all().
1763
Brett Cannon409d8f22005-03-05 06:47:57 +00001764- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001765 (e.g., ``class C(): pass`` is no longer a syntax error).
1766 Patch #1176012 added support to the 'parser' module and 'compiler' package
1767 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001768
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001769- Patch #1115086: Support PY_LONGLONG in structmember.
1770
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001771- Bug #1155938: new style classes did not check that __init__() was
1772 returning None.

1805 current thread state when the auto-GIL-state machinery knows about
1806 it (since the thread state is being deleted, continuing to remember it
1807 can't help, but can hurt if another thread happens to get created with
1808 the same thread id).

2016 in attribute values.
2017
Anthony Baxterc51ee692006-04-01 00:57:31 +00002018- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002019 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002020 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002021 module will not be built.

2046
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002047- email 4.0 package now integrated. This is largely the same as the email 3.0
2048 package that was included in Python 2.3, except that PEP 8 module names are
2049 now used (e.g. mail.message instead of email.Message). The MIME classes
2050 have been moved to a subpackage (e.g. email.mime.text instead of
2051 email.MIMEText). The old names are still supported for now. Several
2052 deprecated Message methods have been removed and lots of bugs have been
2053 fixed. More details can be found in the email package documentation.

2056 (a subclass of tuple) that provides incremental decoders and encoders
2057 (a way to use stateful codecs without the stream API). Python functions
2058 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2059 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2060 have been added.

2063 a ValueError instead of a StopIteration now (like file and cString.String do).
2064 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2065 called before (like file and StringIO.StringIO do).

Tim Peterse3547fd2005-12-16 23:13:57 +00002139 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2140 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2141 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2142 Ronald L. Rivest offered this advice for Python:
2143
2144 "The consensus of researchers in this area (at least as
2145 expressed at the NIST Hash Function Workshop 10/31/05),
2146 is that SHA-256 is a good choice for the time being, but
2147 that research should continue, and other alternatives may
2148 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002149

2302
Martin v. Löwis4afe1542005-03-01 08:09:28 +00002303- Patch #1121234: Properly cleanup _exit and tkerror commands.
2304
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00002305- Patch #1049151: xdrlib now unpacks booleans as True or False.
2306
Raymond Hettingerbab41432005-02-05 01:31:19 +00002307- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2308
Guido van Rossumd0641422005-02-03 15:01:24 +00002309- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2310 disables recursive traversal through instance attributes, which can
2311 be exploited in various ways.
2312
Tim Peterse3547fd2005-12-16 23:13:57 +00002313- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002314 flags on the HTTP listening socket.
2315
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002316- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2317 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2318
Fred Drakefbdeaad2006-07-29 16:56:15 +00002319- Patches #893642, #1039083: add allow_none, encoding arguments to
2320 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002321

Thomas Hellerd6c6e222005-01-20 19:20:16 +00002324- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2325
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002326- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2327
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002328- Enhancements to the csv module:
2329
2330 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002331 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002332 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002333 + Dialect parameter parsing has been re-implemented to improve error
2334 reporting.
2335 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2336 dictates.
2337 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002338 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002339 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002340 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2341 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002342 + reader now allows \r characters to be quoted (previously it only allowed
2343 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002344 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002345 + Dialect classes passed to the module are no longer instantiated by
2346 the module before being parsed (the former validation scheme required
2347 this, but the mechanism was unreliable).
2348 + The dialect registry now contains instances of the internal
2349 C-coded dialect type, rather than references to python objects.
2350 + the internal c-coded dialect type is now immutable.
2351 + register_dialect now accepts the same keyword dialect specifications
2352 as the reader and writer, allowing the user to register dialects
2353 without first creating a dialect class.
2354 + a configurable limit to the size of parsed fields has been added -
2355 previously, an unmatched quote character could result in the entire
2356 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002357 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002358 the parser field size limit (returning the former limit). The initial
2359 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002360 + A line_num attribute has been added to the reader object, which tracks
2361 the number of lines read from the source iterator. This is not
2362 the same as the number of records returned, as records can span
2363 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002364 + reader and writer objects were not being registered with the cyclic-GC.
2365 This has been fixed.
2366
Brett Cannone6539c42005-01-08 02:43:53 +00002367- _DummyThread objects in the threading module now delete self.__block that is
2368 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2369 lock primitives tend to be limited in number and thus should not be wasted on
2370 a _DummyThread object. Fixes bug #1089632.
2371
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002372- The imghdr module now detects Exif files.
2373
Raymond Hettinger6065d322004-12-20 23:51:53 +00002374- StringIO.truncate() now correctly adjusts the size attribute.
2375 (Bug #951915).
2376
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002377- locale.py now uses an updated locale alias table (built using
2378 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2379 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002380 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002381
Raymond Hettinger3557f422004-12-07 12:02:02 +00002382- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2383
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002384- the pickle module no longer accepts the deprecated None option in the
2385 args tuple returned by __reduce__().
2386
Brett Cannon84667c02004-12-07 03:25:18 +00002387- optparse now optionally imports gettext. This allows its use in setup.py.
2388
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002389- the pickle module no longer uses the deprecated bin parameter.
2390
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002391- the shelve module no longer uses the deprecated binary parameter.
2392
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002393- the pstats module no longer uses the deprecated ignore() method.
2394
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002395- the filecmp module no longer uses the deprecated use_statcache argument.
2396
Raymond Hettinger664347b2004-12-04 21:21:53 +00002397- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2398 extended or overridden by subclasses. Formerly, the subclassed method would
2399 be ignored by the rest of the module. (Bug #1078905).
2400
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002401- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002402 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002403
Walter Dörwald36733692004-12-22 12:50:50 +00002404- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2405 once when a size argument is given. This prevents a buffer overflow in the
2406 tokenizer with very long source lines.
2407
Barry Warsaw538561e2006-01-01 21:48:54 +00002408- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2409 immediately after creating the object, without any intervening
2410 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002411
Skip Montanaro05885812005-01-16 20:48:27 +00002412- The reconvert.quote function can now emit triple-quoted strings. The
2413 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002414
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002415- ``UserString.MutableString`` now supports negative indices in
2416 ``__setitem__`` and ``__delitem__``
2417
Greg Ward40407942005-03-05 02:53:17 +00002418- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2419 correctly.
2420
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002421- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2422 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2423 character even if the user has passed a size parameter to get a proper
2424 line ending. Remove the special handling of a "\r\n" that has been split
2425 between two lines.
2426
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002427- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2428 about illegal code points. The codec now supports PEP 293 style error
2429 handlers.
2430
Walter Dörwald78a78b02005-09-01 12:04:29 +00002431- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002432 from the input stream, so that the output is a byte string in the correct
2433 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002434
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002435- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2436 considering it exactly like a '*'.
2437
Walter Dörwald007f8df2005-10-09 19:42:27 +00002438- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2439 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002440
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002441- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2442
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002443- Patch #1413711: Certain patterns of differences were making difflib
2444 touch the recursion limit.
2445
Walter Dörwald58917a62006-03-31 15:26:22 +00002446- Bug #947906: An object oriented interface has been added to the calendar
2447 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002448 called as a script (e.g. via ``python -mcalendar``). Localized month and
2449 weekday names can be ouput (even if an exotic encoding is used) using
2450 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002451
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002452Build
2453-----
2454
Neal Norwitz602d3392006-03-31 08:21:40 +00002455- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2456 by using -mieee gcc option.
2457
Martin v. Löwis86d66262006-02-17 08:40:11 +00002458- Patch #1432345: Make python compile on DragonFly.
2459
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002460- Build support for Win64-AMD64 was added.
2461
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002462- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2463
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002464- Patch #881820: look for openpty and forkpty also in libbsd.
2465
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002466- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2467 The zlib module is now builtin on Windows.
2468
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002469- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2470
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002471- Bug #1189330: configure did not correctly determine the necessary
2472 value of LINKCC if python was built with GCC 4.0.
2473
Trent Mick8321b422005-07-26 02:29:21 +00002474- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2475 vulnerability in zlib 1.2.1 and 1.2.2.
2476
Brett Cannon08cd5982005-04-24 22:26:38 +00002477- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2478 flags that change binary compatibility. Changes were also made to
2479 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002480 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002481
Bob Ippolitoed233462005-03-29 13:47:59 +00002482- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2483 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2484 no longer exists). This configure patch makes things right.
2485
Martin v. Löwise2713be2005-03-08 15:03:08 +00002486- Bug #1158607: Build with --disable-unicode again.
2487
Brett Cannon46d96232005-02-16 00:07:19 +00002488- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2489 defined. Discovered as a result of not being able to build on OS X.
2490
Brett Cannon516592f2004-12-07 00:42:59 +00002491- setup.py now uses the directories specified in LDFLAGS using the -L option
2492 and in CPPFLAGS using the -I option for adding library and include
2493 directories, respectively, for compiling extension modules against. This has
2494 led to the core being compiled using the values in CPPFLAGS. It also removes
2495 the need for the special-casing of both DarwinPorts and Fink for darwin since
2496 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2497 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2498 Fink, ``-I/opt/local/include`` for DarwinPorts).
2499
Brett Cannon43802422005-02-10 20:48:03 +00002500- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2501 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2502 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2503 Closes bug #1096244. Thanks Gregory Bond.
2504
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002505C API
2506-----
2507
Tim Petersc9d78aa2006-03-26 23:27:58 +00002508- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2509 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2510 is obtained via the ``PyObject_`` family, it must be released via the
2511 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2512 always been officially true, but when Python's small-object allocator was
2513 introduced, an attempt was made to cater to a few extension modules
2514 discovered at the time that obtained memory via ``PyObject_New`` but
2515 released it via ``PyMem_DEL``. It's years later, and if such code still
2516 exists it will fail now (probably with segfaults, but calling wrong
2517 low-level memory management functions can yield many symptoms).
2518
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002519- Added a C API for set and frozenset objects.
2520
Raymond Hettinger66517482004-12-03 11:45:13 +00002521- Removed PyRange_New().
2522
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002523- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2524 mapping argument now. This string is used as a mapping table. Byte values
2525 greater than the length of the string and 0xFFFE are treated as undefined
2526 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002533
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002534- Patch #1276356: New resource "urlfetch" is implemented. This enables
