Andrew M. Kuchling43889c02006-09-27 16:37:30 +0000349- Bug #1552726: in readline.c, avoid repeatedly polling in interactive
350 mode by only placing a timeout on the select() if an input hook has
351 been defined. This prevents an interactive Python from waking up 10
352 times per second. Patch by Richard Boulton.

358-----
359
Brett Cannon92d54d52007-01-04 00:23:49 +0000360- Added test.test_support.EnvironmentVarGuard. It's a class that provides a
361 context manager so that one can temporarily set or unset environment
362 variables.
363
Brett Cannon6d9520c2006-12-13 23:09:53 +0000364- Added guard_warnings_filter to test.test_support. It returns a context
365 manager that protects the 'warnings' module's filter from being mutated
366 once the context has been exited.
367
Thomas Heller112d1a62006-10-27 19:05:53 +0000368- Added some tests for modulefinder.

450Core and builtins
451-----------------
452
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000453- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000454 compared equal or unequal to a string and a UnicodeDecodeError
455 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000456
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000457 Instead, the equal (==) and unequal (!=) comparison operators will
458 now issue a UnicodeWarning and interpret the two objects as
459 unequal. The UnicodeWarning can be filtered as desired using
460 the warning framework, e.g. silenced completely, turned into an
461 exception, logged, etc.
462
463 Note that compare operators other than equal and unequal will still
464 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000465
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000466- Fix segfault when doing string formatting on subclasses of long.
467
468- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
469 with new-style classes.
470
471- Fix bug related to __len__ functions returning negative values with
472 classic classes.
473
474- Patch #1538606, Fix __index__() clipping. There were some problems
475 discovered with the API and how integers that didn't fit into Py_ssize_t
476 were handled. This patch attempts to provide enough alternatives
477 to effectively use __index__.
478
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000479- Bug #1536021: __hash__ may now return long int; the final hash
480 value is obtained by invoking hash on the long int.
481
Thomas Hellerab1049c2006-08-08 17:37:00 +0000482- Bug #1536786: buffer comparison could emit a RuntimeWarning.
483
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000484- Bug #1535165: fixed a segfault in input() and raw_input() when
485 sys.stdin is closed.
486
Thomas Heller74d36f02006-08-04 18:17:40 +0000487- On Windows, the PyErr_Warn function is now exported from
488 the Python dll again.
489
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000490- Bug #1191458: tracing over for loops now produces a line event
491 on each iteration. Fixing this problem required changing the .pyc
492 magic number. This means that .pyc files generated before 2.5c1
493 will be regenerated.
494
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000495- Bug #1333982: string/number constants were inappropriately stored
496 in the byte code and co_consts even if they were not used, ie
497 immediately popped off the stack.
498
Georg Brandle9462c72006-08-04 18:03:37 +0000499- Fixed a reference-counting problem in property().

502Library
503-------
504
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000505- Fix a bug in the ``compiler`` package that caused invalid code to be
506 generated for generator expressions.
507
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000508- The distutils version has been changed to 2.5.0. The change to
509 keep it programmatically in sync with the Python version running
510 the code (introduced in 2.5b3) has been reverted. It will continue
511 to be maintained manually as static string literal.
512
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000513- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000514 and this cannot be converted to the required C type, an exception is
515 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000516 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000517
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000518- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000519 an exception.
520
Tim Petersc10c9d02006-09-05 02:18:09 +0000521- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000522 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000523 workarounds for clocks with low resolution, to stop the code yielding
524 duplicate UUIDs.
525
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000526- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
527 before raising SystemExit, allowing IDLE to honor quit() and exit().
528
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000529- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
530
Georg Brandl7a1af772006-08-14 21:55:28 +0000531- Patch #1536071: trace.py should now find the full module name of a
532 file correctly even on Windows.
533
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000534- logging's atexit hook now runs even if the rest of the module has
535 already been cleaned up.
536
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000537- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000538
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000539- Bug #1531405, format_exception no longer raises an exception if
540 str(exception) raised an exception.
541
Neil Schemenauer06ded092006-08-04 16:20:30 +0000542- Fix a bug in the ``compiler`` package that caused invalid code to be
543 generated for nested functions.

556
Thomas Heller86720042006-08-14 11:17:48 +0000557- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
558 uses the _as_parameter_ attribute when objects are passed to foreign
559 function calls. The ctypes version number was changed to 1.0.1.
560
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000561- Bug #1530559, struct.pack raises TypeError where it used to convert.
562 Passing float arguments to struct.pack when integers are expected
563 now triggers a DeprecationWarning.

Neal Norwitza1f10902006-07-12 07:28:29 +0000612
613Core and builtins
614-----------------
615
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000616- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000617 returned a long (see PEP 353).
618
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000619- Bug #1515471: string.replace() accepts character buffers again.
620
Neal Norwitz07aadb12006-07-30 06:55:48 +0000621- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
622 This provides the proper warning for struct.pack().
623 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
624
Neal Norwitz0d62a062006-07-30 06:53:31 +0000625- Patch #1531113: Fix augmented assignment with yield expressions.
626 Also fix a SystemError when trying to assign to yield expressions.
627
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000628- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
629 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
630 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
631 excessive filesystem operations during imports.
632
Tim Petersbc24eee2006-07-27 01:14:53 +0000633- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
634 operations on signed longs that are formally undefined by C.
635 Unfortunately, at least one compiler now cares about that, so complicated
636 the code to make that compiler happy again.
637
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000638- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
639
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000640- Patch #1232023: Stop including current directory in search
641 path on Windows.
642
Neal Norwitze1fdb322006-07-21 05:32:28 +0000643- Fix some potential crashes found with failmalloc.
644
Neal Norwitze7563102006-07-17 01:00:16 +0000645- Fix warnings reported by Klocwork's static analysis tool.
646
Neal Norwitz84be93b2006-07-16 01:50:38 +0000647- Bug #1512814, Fix incorrect lineno's when code within a function
648 had more than 255 blank lines.
649
Georg Brandl9dceedb2006-07-12 15:31:17 +0000650- Patch #1521179: Python now accepts the standard options ``--help`` and
651 ``--version`` as well as ``/?`` on Windows.
652
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000653- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000654 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000655 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000656
Tim Peters112aad32006-07-19 00:03:19 +0000657- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000658 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000659 new ``sys._current_frames()`` returns a dictionary with one entry,
660 mapping the faux "thread id" 0 to the current frame.
661
Ronald Oussoren3075e162006-07-25 20:28:55 +0000662- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000663
Ronald Oussoren3075e162006-07-25 20:28:55 +0000664
Neal Norwitza1f10902006-07-12 07:28:29 +0000665Library
666-------
667
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000668- Correction of patch #1455898: In the mbcs decoder, set final=False
669 for stream decoder, but final=True for the decode function.
670
Georg Brandl07fec3a2006-08-01 18:49:24 +0000671- os.urandom no longer masks unrelated exceptions like SystemExit or
672 KeyboardInterrupt.
673
Tim Peters4643c2f2006-08-10 22:45:34 +0000674- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000675 shutil.copytree on Windows
676
Georg Brandle34ac7c2006-07-30 11:07:23 +0000677- Bug #1002398: The documentation for os.path.sameopenfile now correctly
678 refers to file descriptors, not file objects.
679
Tim Petersc10c9d02006-09-05 02:18:09 +0000680- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000681 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000682 #1513611, and probably others.
683
Georg Brandledd9b0d2006-07-29 09:33:26 +0000684- Bug #1441397: The compiler module now recognizes module and function
685 docstrings correctly as it did in Python 2.4.
686
Tim Peters6f681472006-07-27 23:44:37 +0000687- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
688 lost that tests are sorted by name before being run. This rarely
689 matters for well-written tests, but can create baffling symptoms if
690 side effects from one test to the next affect outcomes. ``DocTestFinder``
691 has been changed to sort the list of tests it returns.
692
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000693- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000694 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000695
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000696- Bug #978833: Really close underlying socket in _socketobject.close.
697
Georg Brandl8c036cc2006-08-20 13:15:39 +0000698- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
699 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000700
Georg Brandlcf0c1722006-07-26 07:23:32 +0000701- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
702 to recursive calls and call it with the failing package name.
703
Martin v. Löwis0b483032006-07-25 09:53:12 +0000704- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
705
Georg Brandlc13c34c2006-07-24 14:09:56 +0000706- Patch #1515343: Fix printing of deprecated string exceptions with a
707 value in the traceback module.
708
Greg Ward48fae7a2006-07-23 16:05:51 +0000709- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
710
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000711- Patch #1524429: Use repr() instead of backticks in Tkinter again.
712
Brett Cannoncaebe222006-07-18 04:41:36 +0000713- Bug #1520914: Change time.strftime() to accept a zero for any position in its
714 argument tuple. For arguments where zero is illegal, the value is forced to
715 the minimum value that is correct. This is to support an undocumented but
716 common way people used to fill in inconsequential information in the time
717 tuple pre-2.4.
718
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000719- Patch #1220874: Update the binhex module for Mach-O.
720
Barry Warsawb110bad2006-07-21 14:51:07 +0000721- The email package has improved RFC 2231 support, specifically for
722 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
723 (name*0=<blah>) parameter continuations. This may change the types of
724 values returned from email.message.Message.get_param() and friends.
725 Specifically in some cases where non-encoded continuations were used,
726 get_param() used to return a 3-tuple of (None, None, string) whereas now it
727 will just return the string (since non-encoded continuations don't have
728 charset and language parts).
729
730 Also, whereas % values were decoded in all parameter continuations, they are
731 now only decoded in encoded parameter parts.
732
Ronald Oussoren3075e162006-07-25 20:28:55 +0000733- Bug #1517990: IDLE keybindings on MacOS X now work correctly
734
735- Bug #1517996: IDLE now longer shows the default Tk menu when a
736 path browser, class browser or debugger is the frontmost window on MacOS X
737
Barry Warsaw00decd72006-07-27 23:43:15 +0000738- Patch #1520294: Support for getset and member descriptors in types.py,
739 inspect.py, and pydoc.py. Specifically, this allows for querying the type
740 of an object against these built-in types and more importantly, for getting
741 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +0000744Extension Modules
745-----------------
746
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000747- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
748 a socket operation on a socket with a timeout, the exception will be
749 caught correctly. Previously, the exception was not caught.
750
Thomas Heller1393d6a2006-07-28 21:43:20 +0000751- Patch #1529514: The _ctypes extension is now compiled on more
752 openbsd target platforms.
753
Tim Peters9cab5932006-07-28 00:30:00 +0000754- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
755 a memory leak, affecting pickles and deep copies.
756
Tim Petersbc24eee2006-07-27 01:14:53 +0000757- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000758 Paul Eggert.
759
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000760- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
761
Thomas Hellerce049a02006-07-14 17:51:14 +0000762- Patch #1521817: Index range checking on ctypes arrays containing
763 exactly one element enabled again. This allows iterating over these
764 arrays, without the need to check the array size before.
765
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000766- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000767 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000768 /dev/null in certain cases; this is now fixed.
769
Thomas Heller47d7a062006-07-12 08:43:47 +0000770- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
771 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000772
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000773- Because of a misspelled preprocessor symbol, ctypes was always
774 compiled without thread support; this is now fixed.
775
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000776- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
777 methods now allow their database parameter to be None as the
778 sleepycat API allows.
779
Matt Flemingec926502006-07-28 11:27:27 +0000780- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
781 bluetooth API compared with Linux and FreeBSD.
782
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000783Tests
784-----
785
786- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
787 how long the test file should take to play. Now accepts taking 2.93 secs
788 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
789
Georg Brandl4793aa32006-07-28 18:31:39 +0000790- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
791 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
792 run via ``regrtest.py``. Now they do.

Martin v. Löwis0907f4d2006-07-30 14:09:47 +0000794Build
795-----
796
797- Bug #1439538: Drop usage of test -e in configure as it is not portable.
798
Ronald Oussoren26cad082006-08-01 21:00:57 +0000799Mac
800---
801
802- PythonLauncher now works correctly when the path to the script contains
803 characters that are treated specially by the shell (such as quotes).
804
805- Bug #1527397: PythonLauncher now launches scripts with the working directory
806 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000807 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000808 expect.

816Core and builtins
817-----------------
818
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000819- Bug #1441486: The literal representation of -(sys.maxint - 1)
820 again evaluates to a int object, not a long.
821
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000822- Bug #1501934: The scope of global variables that are locally assigned
823 using augmented assignment is now correctly determined.
824
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000825- Bug #927248: Recursive method-wrapper objects can now safely
826 be released.
827
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000828- Bug #1417699: Reject locale-specific decimal point in float()
829 and atof().
830
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000831- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
832 omit a default "error" argument for NULL pointer. This allows
833 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000834
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000835- Bug #1519018: 'as' is now validated properly in import statements.
836
Neal Norwitz28746ab2006-07-09 22:14:42 +0000837- On 64 bit systems, int literals that use less than 64 bits are
838 now ints rather than longs.
839
Neal Norwitzed657552006-07-10 00:04:44 +0000840- Bug #1512814, Fix incorrect lineno's when code at module scope
841 started after line 256.
842
Tim Peters32a83612006-07-10 21:08:24 +0000843- New function ``sys._current_frames()`` returns a dict mapping thread
844 id to topmost thread stack frame. This is for expert use, and is
845 especially useful for debugging application deadlocks. The functionality
846 was previously available in Fazal Majid's ``threadframe`` extension
847 module, but it wasn't possible to do this in a wholly threadsafe way from
848 an extension.

851-------
852
Martin v. Löwis77621582006-07-30 13:27:31 +0000853- Bug #1257728: Mention Cygwin in distutils error message about a missing

857
Tim Peters32a83612006-07-10 21:08:24 +0000858- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000859 environment variable to be set in order to the SDK environment
860 for finding the compiler, include files, etc.
861
Martin v. Löwis388a8c22006-07-06 19:28:03 +0000862- Bug #1515998: Properly generate logical ids for files in bdist_msi.
863
Nick Coghlan2d792252006-07-06 13:47:18 +0000864- warnings.py now ignores ImportWarning by default
865
Thomas Woutersadd19112006-07-05 11:03:49 +0000866- string.Template() now correctly handles tuple-values. Previously,
867 multi-value tuples would raise an exception and single-value tuples would
868 be treated as the value they contain, instead.
869
Martin v. Löwisede77f52006-07-03 13:01:35 +0000870- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
871 even if some data are received.
872
Martin v. Löwis45482392006-07-03 12:28:58 +0000873- Bug #1267547: Put proper recursive setup.py call into the
874 spec file generated by bdist_rpm.
875
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000876- Bug #1514693: Update turtle's heading when switching between
877 degrees and radians.
878
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000879- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000880 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000881
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000882- Bug #1514703: Only setup canvas window in turtle when the canvas
883 is created.
884
Martin v. Löwis7596e832006-07-01 15:33:37 +0000885- Bug #1513223: .close() of a _socketobj now releases the underlying
886 socket again, which then gets closed as it becomes unreferenced.
887
Fred Drake10497c82006-06-29 02:57:48 +0000888- Bug #1504333: Make sgmllib support angle brackets in quoted
889 attribute values.
890
891- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
892 sgmllib ('[' and ']' were not accepted).
893
Georg Brandl1be63af2006-06-28 20:23:25 +0000894- Fix a bug in the turtle module's end_fill function.
895
Brett Cannon53ab5b72006-06-22 16:49:14 +0000896- Bug #1510580: The 'warnings' module improperly required that a Warning
897 category be either a types.ClassType and a subclass of Warning. The proper
898 check is just that it is a subclass with Warning as the documentation states.
899
Georg Brandlad29e632006-06-21 17:45:17 +0000900- The compiler module now correctly compiles the new try-except-finally
901 statement (bug #1509132).
902
Neal Norwitz60373cd2006-06-22 06:30:50 +0000903- The wsgiref package is now installed properly on Unix.
904
Vinay Sajip28e57612006-07-01 10:45:20 +0000905- A bug was fixed in logging.config.fileConfig() which caused a crash on
906 shutdown when fileConfig() was called multiple times.
907
Gerhard Häring762fbd32006-07-02 17:48:30 +0000908- The sqlite3 module did cut off data from the SQLite database at the first
909 null character before sending it to a custom converter. This has been fixed
910 now.

913-----------------
914
Tim Peters112aad32006-07-19 00:03:19 +0000915- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
916 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
917 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000918
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000919- Assigning None to pointer type fields in ctypes structures possible
920 overwrote the wrong fields, this is fixed now.
921
922- Fixed a segfault in _ctypes when ctypes.wintypes were imported
923 on non-Windows platforms.
924
925- Bug #1518190: The ctypes.c_void_p constructor now accepts any
926 integer or long, without range checking.
927
928- Patch #1517790: It is now possible to use custom objects in the ctypes
929 foreign function argtypes sequence as long as they provide a from_param
930 method, no longer is it required that the object is a ctypes type.
931
932- The '_ctypes' extension module now works when Python is configured
933 with the --without-threads option.
934
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000935- Bug #1513646: os.access on Windows now correctly determines write
936 access, again.
937
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000938- Bug #1512695: cPickle.loads could crash if it was interrupted with
939 a KeyboardInterrupt.
940
Neal Norwitza12aa882006-07-06 06:45:08 +0000941- Bug #1296433: parsing XML with a non-default encoding and
942 a CharacterDataHandler could crash the interpreter in pyexpat.
943

Martin v. Löwisd73168d2006-07-14 09:58:55 +0000949- Automate Windows build process for the Win64 SSL module.
950
Tim Peters32a83612006-07-10 21:08:24 +0000951- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000952 Previously, the slight difference could cause compilation errors of the
953 'zlib' module on systems with more than one version of zlib.
954
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000955- The MSI compileall step was fixed to also support a TARGETDIR
956 with spaces in it.

Anthony Baxter51bcb682006-04-05 14:51:42 +0000985
986Core and builtins
987-----------------
988
Georg Brandla56b9152006-06-19 06:35:54 +0000989- Patch #1507676: Error messages returned by invalid abstract object operations
990 (such as iterating over an integer) have been improved and now include the
991 type of the offending object to help with debugging.
992
Brett Cannonea3912b2006-06-13 21:46:41 +0000993- Bug #992017: A classic class that defined a __coerce__() method that returned
994 its arguments swapped would infinitely recurse and segfault the interpreter.
995
Neal Norwitz909eb122006-06-12 02:13:21 +0000996- Fix the socket tests so they can be run concurrently.
997
Neal Norwitzb9845e72006-06-12 02:11:18 +0000998- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000999 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001000
Brett Cannon22565aa2006-06-09 22:31:23 +00001001- Bug #532646: object.__call__() will continue looking for the __call__
1002 attribute on objects until one without one is found. This leads to recursion
1003 when you take a class and set its __call__ attribute to an instance of the
1004 class. Originally fixed for classic classes, but this fix is for new-style.
1005 Removes the infinite_rec_3 crasher.
1006
Georg Brandl24250812006-06-09 18:45:48 +00001007- The string and unicode methods startswith() and endswith() now accept
1008 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1009
Brett Cannonde3b0522006-06-08 17:00:45 +00001010- Buffer objects, at the C level, never used the char buffer
1011 implementation even when the char buffer for the wrapped object was
1012 explicitly requested (originally returned the read or write buffer).
1013 Now a TypeError is raised if the char buffer is not present but is
1014 requested.
1015
Georg Brandlddbaa662006-06-04 21:56:52 +00001016- Patch #1346214: Statements like "if 0: suite" are now again optimized
1017 away like they were in Python 2.4.
1018
Georg Brandlb7c8f542006-05-27 12:30:25 +00001019- Builtin exceptions are now full-blown new-style classes instead of
1020 instances pretending to be classes, which speeds up exception handling
1021 by about 80% in comparison to 2.5a2.
1022
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001023- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1024 Unicode 4.1.
1025
Georg Brandlf4ef1162006-05-26 18:03:31 +00001026- Patch #921466: sys.path_importer_cache is now used to cache valid and
1027 invalid file paths for the built-in import machinery which leads to
1028 fewer open calls on startup.
1029
Tim Peters696cf432006-05-24 21:10:40 +00001030- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1031 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1032 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1033 the number of input digits (it was and remains linear-time for bases
1034 2, 4, 8, 16 and 32).
1035
Tim Petersb713ec22006-05-23 18:45:30 +00001036- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1037 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1038 an integer close to ``sys.maxint``. This was repaired by patch
1039 #1335972, which also gives a nice speedup.
1040
Richard Jonescebbefc2006-05-23 18:28:17 +00001041- Patch #1337051: reduced size of frame objects.
1042
1043- PyErr_NewException now accepts a tuple of base classes as its
1044 "base" parameter.
1045
Richard Jones7c88dcc2006-05-23 10:37:38 +00001046- Patch #876206: function call speedup by retaining allocated frame
1047 objects.
1048
Georg Brandl7b90e162006-05-18 07:01:27 +00001049- Bug #1462152: file() now checks more thoroughly for invalid mode
1050 strings and removes a possible "U" before passing the mode to the
1051 C library function.
1052
Neal Norwitz1004a532006-05-15 07:17:23 +00001053- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1054
Neal Norwitz373f0a72006-05-15 07:04:36 +00001055- Bug #1487966: Fix SystemError with conditional expression in assignment
1056
Martin v. Löwis879768d2006-05-11 13:28:43 +00001057- WindowsError now has two error code attributes: errno, which carries
1058 the error values from errno.h, and winerror, which carries the error
1059 values from winerror.h. Previous versions put the winerror.h values
1060 (from GetLastError()) into the errno attribute.
1061
Martin v. Löwis77736712006-05-04 05:51:03 +00001062- Patch #1475845: Raise IndentationError for unexpected indent.
1063
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001064- Patch #1479181: split open() and file() from being aliases for each other.
1065
Tim Peters44bd9862006-06-01 13:49:23 +00001066- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1067 methods were always silently ignored by dictionaries when comparing keys.
1068 They are now passed through (except when using the C API function
1069 ``PyDict_GetItem()``, whose semantics did not change).
1070
1071- Bug #1456209: In some obscure cases it was possible for a class with a
1072 custom ``__eq__()`` method to confuse dict internals when class instances
1073 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1074 No, you don't have any code that did this ;-)

1082
Brett Cannon6ee7d012006-06-08 16:23:04 +00001083- Change binascii.hexlify to accept a read-only buffer instead of only a char
1084 buffer and actually follow its documentation.
1085
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001086- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1087
Nick Coghlanc649ec52006-05-29 12:43:05 +00001088- Patch #1478788 (modified version): The functional extension module has
1089 been renamed to _functools and a functools Python wrapper module added.
1090 This provides a home for additional function related utilities that are
1091 not specifically about functional programming. See PEP 309.
1092
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001093- Patch #1493701: performance enhancements for struct module.

Georg Brandl8d3342b2006-05-16 07:38:27 +00001097- Patch #1435422: zlib's compress and decompress objects now have a
1098 copy() method.
1099
Andrew MacIntyre92913322006-06-13 15:04:24 +00001100- Patch #1454481: thread stack size is now tunable at runtime for thread
1101 enabled builds on Windows and systems with Posix threads support.
1102
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001103- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1104 (up to the system limit of 32K characters).
1105
1106- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1107 As a result, these functions now raise WindowsError instead of OSError.
1108
Tim Peters7a822da2006-05-25 21:50:17 +00001109- ``time.clock()`` on Win64 should use the high-performance Windows
1110 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1111 Windows platforms).
1112
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001113- Calling Tk_Init twice is refused if the first call failed as that
1114 may deadlock.
1115
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001116- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1117 accept it without potentially using an uninitialized pointer.
1118
1119- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1120 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

Gregory P. Smith372b5832006-06-05 18:48:21 +00001126- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1127 parameter is supplied. [SF pybsddb bug #1477863]
1128
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001129- bsddb: the __len__ method of a DB object has been fixed to return correct
1130 results. It could previously incorrectly return 0 in some cases.
1131 Fixes SF bug 1493322 (pybsddb bug 1184012).
1132
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001133- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1134 aborts the db transaction safely when a modifier callback fails.
1135 Fixes SF python patch/bug #1408584.
1136
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001137- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001138 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001139 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1140 database calls that would previously deadlock. [SF python bug #775414]

1170 double-byte encodings.
1171
Tim Peters43898b42006-06-14 04:09:25 +00001172- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1173 guarantee that adjacent triples in the return list always describe
1174 non-adjacent blocks. Previously, a pair of matching blocks could end
1175 up being described by multiple adjacent triples that formed a partition
1176 of the matching pair.
1177
Greg Ward0e0c9f42006-06-11 16:24:11 +00001178- Bug #1498146: fix optparse to handle Unicode strings in option help,

1184 clarify docs.
1185
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001186- The wsgiref package has been added to the standard library.
1187
Nick Coghlan676725d2006-06-08 13:54:49 +00001188- The functions update_wrapper() and wraps() have been added to the functools
1189 module. These make it easier to copy relevant metadata from the original
1190 function when writing wrapper functions.
1191
Tim Petersd6a9eef2006-06-05 01:48:21 +00001192- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1193 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001194
Martin v. Löwis3f767792006-06-04 19:36:28 +00001195- Patch #1359618: Speed up charmap encoder by using a trie structure
1196 for lookup.
1197
Tim Petersd609b1a2006-06-02 23:22:51 +00001198- The functions in the ``pprint`` module now sort dictionaries by key
1199 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1200 if and only if its display required more than one line, although that
1201 wasn't documented. The new behavior increases predictability; e.g.,
1202 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1203
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001204- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1205 (thanks for J. J. Lee).
1206
Georg Brandl2b330372006-05-28 20:23:12 +00001207- Patch #1496206: improve urllib2 handling of passwords with respect to
1208 default HTTP and HTTPS ports.
1209
George Yoshidaf3c65de2006-05-28 16:39:09 +00001210- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1211
Bob Ippolito7298f272006-05-23 18:43:47 +00001212- Patch #1281707: speed up gzip.readline.
1213
Georg Brandlb89316f2006-05-17 15:51:16 +00001214- Patch #1180296: Two new functions were added to the locale module:
1215 format_string() to get the effect of "format % items" but locale-aware,
1216 and currency() to format a monetary number with currency sign.
1217
Georg Brandle3a25832006-05-17 14:56:04 +00001218- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1219 and several features added, such as speed and geometry control.
1220
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001221- Patch #1488881: add support for external file objects in bz2 compressed
1222 tarfiles.
1223
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001224- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1225 stdout arguments, making it possible to redirect input and output
1226 for remote debugging.
1227
1228- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1229 a couple of issues, notably handling of long file names using the
1230 GNU LONGNAME extension.
1231
1232- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1233 new flag when ``name`` is already the name of an option flag.
1234
1235- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1236 package.
1237
1238- Patch #1472854: make the rlcompleter.Completer class usable on non-
1239 UNIX platforms.
1240
1241- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1242
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001243- Bug #1472827: correctly escape newlines and tabs in attribute values in
1244 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001274What's New in Python 2.5 alpha 2?
1275=================================
1276
1277*Release date: 27-APR-2006*
1278
1279Core and builtins
1280-----------------
1281
Thomas Heller1b046642006-04-18 18:51:06 +00001282- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1283 by converting these apis from macros into exported functions again:
1284
1285 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1286 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1287 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1288 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1289 PyRun_String Py_CompileString
1290
Martin v. Löwis45294a92006-04-18 06:24:08 +00001291- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1292
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001293- All uses of PyStructSequence_InitType have been changed to initialize
1294 the type objects only once, even if the interpreter is initialized
1295 multiple times.
1296
Neal Norwitz61546162006-04-14 05:20:28 +00001297- Bug #1454485, array.array('u') could crash the interpreter. This was
1298 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1299 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1300
1301- Py_UNICODE is unsigned. It was always documented as unsigned, but
1302 due to a bug had a signed value in previous versions.
1303
Tim Peters3a5e8b12006-04-11 01:44:07 +00001304- Patch #837242: ``id()`` of any Python object always gives a positive
1305 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1306 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001307 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001308 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001309
Tim Peters3a5e8b12006-04-11 01:44:07 +00001310 def __hash__(self):
1311 return id(self) # WRONG
1312
1313 because a hash result must be a (short) Python int but it was always
1314 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001315 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001316 was always usable as a hash value before this patch. That's no longer
1317 necessarily so.
1318
1319- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001320 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001321 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001322 #1454844)
1323
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001324- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1325 involving generators that have paused outside of any ``try`` or ``with``
1326 blocks. (In 2.5a1, a paused generator that was part of a reference
1327 cycle could not be garbage collected, regardless of whether it was
1328 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001329
Anthony Baxter51bcb682006-04-05 14:51:42 +00001330Extension Modules

Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001333- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1334 is a macro.
1335
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001336- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1337 fails with an error condition.
1338
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001339- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1340
1341- Bug #1117761: bsddb.*open() no longer raises an exception when using
1342 the cachesize parameter.
1343
1344- Bug #1149413: bsddb.*open() no longer raises an exception when using
1345 a temporary db (file=None) with the 'n' flag to truncate on open.
1346
1347- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1348 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001349
Armin Rigoa9017c32006-04-19 11:50:27 +00001350- Patch #1062014: AF_UNIX sockets under Linux have a special
1351 abstract namespace that is now fully supported.

1355
Peter Astrand7d1d4362006-07-14 14:04:45 +00001356- Bug #1223937: subprocess.CalledProcessError reports the exit status
1357 of the process using the returncode attribute, instead of
1358 abusing errno.
1359
Tim Peters711bf302006-04-25 03:31:36 +00001360- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1361 a doctest to be skipped (the code is not run, and the expected output
1362 or exception is ignored).
1363
Nick Coghlanda2268f2006-04-24 04:37:15 +00001364- Fixed contextlib.nested to cope with exceptions being raised and
1365 caught inside exit handlers.
1366
Greg Wardab05edc2006-04-23 03:47:58 +00001367- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1368 hex, octal, or binary; add ``append_const`` action; keep going if
1369 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1370 added ``epilog`` for better help generation).
1371
Tim Peters21fbd572006-04-21 21:18:10 +00001372- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1373 called from a thread spawned as a side effect of importing a module.
1374
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001375- The pydoc module now supports documenting packages contained in
1376 .zip or .egg files.
1377
1378- The pkgutil module now has several new utility functions, such
1379 as ``walk_packages()`` to support working with packages that are either
1380 in the filesystem or zip files.
1381
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001382- The mailbox module can now modify and delete messages from
1383 mailboxes, in addition to simply reading them. Thanks to Gregory
1384 K. Johnson for writing the code, and to the 2005 Google Summer of
1385 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001386
Tim Petersc7605f22006-04-17 21:12:33 +00001387- The ``__del__`` method of class ``local`` in module ``_threading_local``
1388 returned before accomplishing any of its intended cleanup.
1389
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001390- Patch #790710: Add breakpoint command lists in pdb.
1391

Martin v. Löwis4b501e62006-04-15 08:41:11 +00001394- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1395
Anthony Baxtere29002c2006-04-12 12:07:31 +00001396- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1397 Windows. Bug #1469163.
1398
Phillip J. Eby47032112006-04-11 01:07:43 +00001399- The warnings, linecache, inspect, traceback, site, and doctest modules
1400 were updated to work correctly with modules imported from zipfiles or
1401 via other PEP 302 __loader__ objects.
1402
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001403- Patch #1467770: Reduce usage of subprocess._active to processes which
1404 the application hasn't waited on.

1411 direct output to an alternate file-like object.
1412
Anthony Baxter51bcb682006-04-05 14:51:42 +00001413Build

1415
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001416- The Makefile now has a reindent target, which runs reindent.py on
1417 the library.
1418
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001419- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis0f48d982006-04-14 14:34:26 +00001423- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1424 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001425 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001426 CXX from --with-cxx-main, see description in README.
1427
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001428- Patch #1429775: Link extension modules with the shared libpython.
1429
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001430- Fixed a libffi build problem on MIPS systems.
1431
Tim Peters8931ff12006-05-13 23:28:20 +00001432- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1433 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1434 and "%zu" for unsigned integers of type ``size_t``.
1435
Anthony Baxter51bcb682006-04-05 14:51:42 +00001436Tests
1437-----
1438
Nick Coghlanda2268f2006-04-24 04:37:15 +00001439- test_contextlib now checks contextlib.nested can cope with exceptions
1440 being raised and caught inside exit handlers.
1441
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001442- test_cmd_line now checks operation of the -m and -c command switches
1443
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001444- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1445 it separately and by hand. It also wasn't cleaning up its changes to
1446 the current Decimal context.
1447
Thomas Woutersabd08882006-04-26 15:53:30 +00001448- regrtest.py now has a -M option to run tests that test the new limits of
1449 containers, on 64-bit architectures. Running these tests is only sensible
1450 on 64-bit machines with more than two gigabytes of memory. The argument
1451 passed is the maximum amount of memory for the tests to use.

Tim Petersb06d28c2006-05-12 01:57:59 +00001462- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1463
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001464- PEP 343: Added Context Types section to the library reference
1465 and attempted to bring other PEP 343 related documentation into
1466 line with the implementation and/or python-dev discussions.
1467
Tim Peters8dc73d22006-04-24 02:03:16 +00001468- Bug #1337990: clarified that ``doctest`` does not support examples
1469 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001472What's New in Python 2.5 alpha 1?
1473=================================
1474
Anthony Baxterebed3f62006-04-03 15:03:44 +00001475*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001476
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001477Core and builtins
1478-----------------
1479
Nick Coghlan43832302006-04-23 17:04:07 +00001480- PEP 338: -m command line switch now delegates to runpy.run_module
1481 allowing it to support modules in packages and zipfiles
1482
Martin v. Löwisc661b882006-04-20 04:54:23 +00001483- On Windows, .DLL is not an accepted file name extension for
1484 extension modules anymore; extensions are only found if they
1485 end in .PYD.
1486
Martin v. Löwisea62d252006-04-03 10:56:49 +00001487- Bug #1421664: sys.stderr.encoding is now set to the same value as
1488 sys.stdout.encoding.
1489
Neal Norwitz92e212f2006-04-03 04:48:37 +00001490- __import__ accepts keyword arguments.
1491
Georg Brandlccadf842006-03-31 18:54:53 +00001492- Patch #1460496: round() now accepts keyword arguments.
1493
Anthony Baxter262c00a2006-03-30 10:53:17 +00001494- Fixed bug #1459029 - unicode reprs were double-escaped.
1495
Hye-Shik Changd478f342006-03-23 12:32:36 +00001496- Patch #1396919: The system scope threads are reenabled on FreeBSD
1497 5.4 and later versions.
1498
Neal Norwitze98ccf62006-03-23 05:39:47 +00001499- Bug #1115379: Compiling a Unicode string with an encoding declaration
1500 now gives a SyntaxError.
1501
Georg Brandlabd1ff82006-03-18 07:59:59 +00001502- Previously, Python code had no easy way to access the contents of a
1503 cell object. Now, a ``cell_contents`` attribute has been added
1504 (closes patch #1170323).
1505
Tim Peterscf79aac2006-03-16 01:14:46 +00001506- Patch #1123430: Python's small-object allocator now returns an arena to
1507 the system ``free()`` when all memory within an arena becomes unused
1508 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1509 freed. Some applications will see a drop in virtual memory size now,
1510 especially long-running applications that, from time to time, temporarily
1511 use a large number of small objects. Note that when Python returns an
1512 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001513 platform C library will in turn return that memory to the operating system.
1514 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001515 appears to be effective at least on Microsoft C and gcc-based systems.
1516 Thanks to Evan Jones for hard work and patience.
1517
Georg Brandl533ff6f2006-03-08 18:09:27 +00001518- Patch #1434038: property() now uses the getter's docstring if there is
1519 no "doc" argument given. This makes it possible to legitimately use
1520 property() as a decorator to produce a read-only property.
1521
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001522- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1523 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1524 of requiring an int or long in slicing and a few other contexts, enabling
1525 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1526
Neal Norwitz995acdf2006-03-07 05:01:00 +00001527- Fixed various bugs reported by Coverity's Prevent tool.
1528
Brett Cannonbf364092006-03-01 04:25:17 +00001529- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1530 new exception base class, BaseException, which has a new message attribute.
1531 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1532 Raising a string exception now raises a DeprecationWarning.
1533
Thomas Woutersfb609f42006-02-28 16:37:25 +00001534- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1535 explicitly relative, using 'from .module import name' to mean 'from the same
1536 package as this module is in. Imports without dots still default to the
1537 old relative-then-absolute, unless 'from __future__ import
1538 absolute_import' is used.
1539
Brett Cannona7446e32006-02-27 23:39:10 +00001540- Properly check if 'warnings' raises an exception (usually when a filter set
1541 to "error" is triggered) when raising a warning for raising string
1542 exceptions.
1543
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001544- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001545 The name was removed from Include/code.h.
1546
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001547- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001548
Guido van Rossum1968ad32006-02-25 22:38:04 +00001549- Patch 1433928:
1550 - The copy module now "copies" function objects (as atomic objects).
1551 - dict.__getitem__ now looks for a __missing__ hook before raising
1552 KeyError.
1553
Tim Peters84ef21c2006-02-28 20:39:06 +00001554- PEP 343: with statement implemented. Needs ``from __future__ import
1555 with_statement``. Use of 'with' as a variable will generate a warning.
1556 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001557 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001558 The following objects have __context__ methods:
1559 - The built-in file type.
1560 - The thread.LockType type.
1561 - The following types defined by the threading module:
1562 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1563 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001564
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001565- Fix the encodings package codec search function to only search
1566 inside its own package. Fixes problem reported in patch #1433198.
1567
1568 Note: Codec packages should implement and register their own
1569 codec search function. PEP 100 has the details.
1570
Tim Peters9ea89d22006-06-04 03:26:02 +00001571- PEP 353: Using ``Py_ssize_t`` as the index type.
1572
1573- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1574 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1575 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1576 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1577 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001578
Neal Norwitzfc76d632006-01-10 06:03:13 +00001579- Patch #1400181, fix unicode string formatting to not use the locale.
1580 This is how string objects work. u'%f' could use , instead of .
1581 for the decimal point. Now both strings and unicode always use periods.
1582
Neal Norwitz671b9e32006-01-09 07:07:12 +00001583- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1584 configure would break checking curses.h.
1585
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001586- Bug #959576: The pwd module is now builtin. This allows Python to be
1587 built on UNIX platforms without $HOME set.
1588
Neal Norwitzc10978f2005-12-19 06:07:16 +00001589- Bug #1072182, fix some potential problems if characters are signed.
1590
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001591- Bug #889500, fix line number on SyntaxWarning for global declarations.
1592
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001593- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1594
Neal Norwitze7214a12005-12-18 05:03:17 +00001595- Support for converting hex strings to floats no longer works.
1596 This was not portable. float('0x3') now raises a ValueError.
1597
Barry Warsaw2a38a862005-12-18 01:27:35 +00001598- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001599 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001600 is now displayed in interactive prompt banner.
1601
Georg Brandlfa166682005-12-17 21:45:17 +00001602- Implementation of PEP 341 - Unification of try/except and try/finally.
1603 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001604 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001605
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001606- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1607 now encodes backslash correctly.
1608
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001609- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1610
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001611- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001612 and long longs.
1613
Neal Norwitz67715f02005-11-09 06:59:35 +00001614- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001615 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001616 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001617
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001618- Replaced most Unicode charmap codecs with new ones using the
1619 new Unicode translate string feature in the builtin charmap
1620 codec; the codecs were created from the mapping tables available
1621 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1622 encodings now include a mapping for the Apple logo)
1623
Tim Peterse3547fd2005-12-16 23:13:57 +00001624- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001625
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001626- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001627
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001628- A new AST parser implementation was completed. The abstract
1629 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001630 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001631
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001632- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001633 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1634
Neal Norwitz708e51a2005-10-03 04:48:15 +00001635- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1636
Neal Norwitz11bd1192005-10-03 00:54:56 +00001637- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1638 Provide a warning when a directory is passed on the command line.
1639
Neal Norwitz40d37812005-10-02 01:48:49 +00001640- Fix segfault with invalid coding.
1641
1642- SF bug #772896: unknown encoding results in MemoryError.
1643
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001644- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001645 supported a __len__() method which evaluated to False when the iterator
1646 was empty.
1647
Guido van Rossum630db602005-09-20 18:49:54 +00001648- On 64-bit platforms, when __len__() returns a value that cannot be
1649 represented as a C int, raise OverflowError.
1650
Skip Montanarof8948ca2005-09-19 03:54:46 +00001651- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001652 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001653
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001654- SF bug #893549: parsing keyword arguments was broken with a few format
1655 codes.
1656
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001657- Changes donated by Elemental Security to make it work on AIX 5.3
1658 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1659 bug #105470: test_pwd fails on 64bit system (Opteron).
1660
Guido van Rossum539c6622005-09-14 17:49:54 +00001661- Changes donated by Elemental Security to make it work on HP-UX 11 on
1662 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1663
Georg Brandl4550b8d2005-08-26 06:43:52 +00001664- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001665 (fixes bug #1119418).
1666
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001667- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1668
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001669- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1670 exceptions that cause a function to exit.
1671
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001672- The implementation of set() and frozenset() was revised to use its
1673 own internal data structure. Memory consumption is reduced by 1/3
1674 and there are modest speed-ups as well. The API is unchanged.
1675
Tim Petersde7990b2005-07-17 23:45:23 +00001676- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1677
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001678- SF bug #1229429: PyObject_CallMethod failed to decrement some
1679 reference counts in some error exit cases.
1680
Tim Petersecc6e6a2005-07-10 22:30:55 +00001681- SF bug #1185883: Python's small-object memory allocator took over
1682 a block managed by the platform C library whenever a realloc specified
1683 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001684 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001685 portable way to copy data from the C-managed block into Python's
1686 small-object space without risking a memory fault. Python's small-object
1687 realloc now leaves such blocks under the control of the platform C
1688 realloc.
1689
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001690- SF bug #1232517: An overflow error was not detected properly when
1691 attempting to convert a large float to an int in os.utime().
1692
Raymond Hettinger3296e692005-06-29 23:29:56 +00001693- SF bug #1224347: hex longs now print with lowercase letters just
1694 like their int counterparts.
1695
Michael W. Hudson188d4362005-06-20 16:52:57 +00001696- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1697 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1698 interpreter states; back out that fix and do a better job (see
1699 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1700 for a longer write-up of the problem).
1701
Michael W. Hudsondf888462005-06-03 14:41:55 +00001702- SF patch #1180995: marshal now uses a binary format by default when
1703 serializing floats.
1704
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001705- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1706 the routines that promise to produce IEEE 754 binary representations
1707 of floats now simply copy bytes around.
1708
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001709- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1710 278.
1711
Brett Cannonc3647ac2005-04-26 03:45:26 +00001712- patch #1109424: int, long, float, complex, and unicode now check for the
1713 proper magic slot for type conversions when subclassed. Previously the
1714 magic slot was ignored during conversion. Semantics now match the way
1715 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001716 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001717 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001718 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001719
Barry Warsawc8d907c2005-04-19 23:43:40 +00001720- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1721 NULL, now raise an AttributeError when attempting to set or delete the
1722 attribute. Previously a TypeError was raised, but this was inconsistent
1723 with the equivalent pure-Python implementation.
1724
Michael W. Hudson774479c2005-04-18 08:46:17 +00001725- It is now safe to call PyGILState_Release() before
1726 PyEval_InitThreads() (note that if there is reason to believe there
1727 are multiple threads around you still must call PyEval_InitThreads()
1728 before using the Python API; this fix is for extension modules that
1729 have no way of knowing if Python is multi-threaded yet).
1730
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001731- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1732 disabled caused a crash.
1733
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001734- Bug #1165306: instancemethod_new allowed the creation of a method
1735 with im_class == im_self == NULL, which caused a crash when called.
1736
Tim Petersecc6e6a2005-07-10 22:30:55 +00001737- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001738 fixes the crash seen in bug #1165761
1739
Raymond Hettinger96229b12005-03-11 06:49:40 +00001740- Added two new builtins, any() and all().
1741
Brett Cannon409d8f22005-03-05 06:47:57 +00001742- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001743 (e.g., ``class C(): pass`` is no longer a syntax error).
1744 Patch #1176012 added support to the 'parser' module and 'compiler' package
1745 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001746
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001747- Patch #1115086: Support PY_LONGLONG in structmember.
1748
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001749- Bug #1155938: new style classes did not check that __init__() was
1750 returning None.
1751
Tim Petersecc6e6a2005-07-10 22:30:55 +00001752- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001753 ('\') with a specific error message.
1754
Martin v. Löwisff232d72005-03-03 09:24:38 +00001755- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1756
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001757- Bug #1124295: the __name__ attribute of file objects was
1758 inadvertently made inaccessible in restricted mode.
1759
Tim Petersecc6e6a2005-07-10 22:30:55 +00001760- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001761 an ferror() call.
1762
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001763- min() and max() now support key= arguments with the same meaning as in

Jeremy Hyltonab630502005-02-04 18:44:06 +00001774- The parser did not complain about future statements in illegal
1775 positions. It once again reports a syntax error if a future
1776 statement occurs after anything other than a doc string.
1777
Neil Schemenauercf52c072005-08-12 17:34:58 +00001778- Change the %s format specifier for str objects so that it returns a
1779 unicode instance if the argument is not an instance of basestring and
1780 calling __str__ on the argument returns a unicode instance.
1781
Tim Petersf4e69282006-02-27 17:15:31 +00001782- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1783 current thread state when the auto-GIL-state machinery knows about
1784 it (since the thread state is being deleted, continuing to remember it
1785 can't help, but can hurt if another thread happens to get created with
1786 the same thread id).

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001978- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1979 been renamed to have only a single underscore prefix. This was done to
1980 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001981
Nick Coghlan43832302006-04-23 17:04:07 +00001982- PEP 338: new module runpy defines a run_module function to support
1983 executing modules which provide access to source code or a code object
1984 via the PEP 302 import mechanisms.
1985
Anthony Baxter93f5b932006-04-03 08:05:07 +00001986- The email module's parsedate_tz function now sets the daylight savings

1994 in attribute values.
1995
Anthony Baxterc51ee692006-04-01 00:57:31 +00001996- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001997 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001998 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001999 module will not be built.
2000
Tim Petersc17976e2006-04-01 00:26:53 +00002001- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2002 aren't officially supported here, and trying to use them will probably
2003 raise an exception some day. But dicts have been allowed, and "mostly
2004 worked", so support for them won't go away without warning.
2005
Georg Brandl338ef7d2006-03-31 18:42:16 +00002006- Bug #1445068: getpass.getpass() can now be given an explicit stream

2024
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002025- email 4.0 package now integrated. This is largely the same as the email 3.0
2026 package that was included in Python 2.3, except that PEP 8 module names are
2027 now used (e.g. mail.message instead of email.Message). The MIME classes
2028 have been moved to a subpackage (e.g. email.mime.text instead of
2029 email.MIMEText). The old names are still supported for now. Several
2030 deprecated Message methods have been removed and lots of bugs have been

2034 (a subclass of tuple) that provides incremental decoders and encoders
2035 (a way to use stateful codecs without the stream API). Python functions
2036 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well

2121
2122 "The consensus of researchers in this area (at least as
2123 expressed at the NIST Hash Function Workshop 10/31/05),
2124 is that SHA-256 is a good choice for the time being, but
2125 that research should continue, and other alternatives may
2126 arise from this research. The larger SHA's also seem OK."

Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002292 flags on the HTTP listening socket.
2293
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002294- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2295 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2296
Fred Drakefbdeaad2006-07-29 16:56:15 +00002297- Patches #893642, #1039083: add allow_none, encoding arguments to
2298 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.

Martin v. Löwis1d11de62005-01-29 13:29:23 +00002300- Bug #1110478: Revert os.environ.update to do putenv again.
2301
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002302- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2303
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002304- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2305
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002306- Enhancements to the csv module:
2307
2308 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002309 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002310 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002311 + Dialect parameter parsing has been re-implemented to improve error
2312 reporting.
2313 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2314 dictates.
2315 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002316 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002317 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002318 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2319 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002320 + reader now allows \r characters to be quoted (previously it only allowed
2321 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002322 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002323 + Dialect classes passed to the module are no longer instantiated by
2324 the module before being parsed (the former validation scheme required
2325 this, but the mechanism was unreliable).
2326 + The dialect registry now contains instances of the internal
2327 C-coded dialect type, rather than references to python objects.
2328 + the internal c-coded dialect type is now immutable.
2329 + register_dialect now accepts the same keyword dialect specifications
2330 as the reader and writer, allowing the user to register dialects
2331 without first creating a dialect class.
2332 + a configurable limit to the size of parsed fields has been added -
2333 previously, an unmatched quote character could result in the entire
2334 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002335 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002336 the parser field size limit (returning the former limit). The initial
2337 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002338 + A line_num attribute has been added to the reader object, which tracks
2339 the number of lines read from the source iterator. This is not
2340 the same as the number of records returned, as records can span
2341 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002342 + reader and writer objects were not being registered with the cyclic-GC.
2343 This has been fixed.
2344
Brett Cannone6539c42005-01-08 02:43:53 +00002345- _DummyThread objects in the threading module now delete self.__block that is
2346 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2347 lock primitives tend to be limited in number and thus should not be wasted on
2348 a _DummyThread object. Fixes bug #1089632.
2349
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002350- The imghdr module now detects Exif files.
2351
Raymond Hettinger6065d322004-12-20 23:51:53 +00002352- StringIO.truncate() now correctly adjusts the size attribute.
2353 (Bug #951915).
2354
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002355- locale.py now uses an updated locale alias table (built using
2356 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2357 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002358 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002359
Raymond Hettinger3557f422004-12-07 12:02:02 +00002360- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2361
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002362- the pickle module no longer accepts the deprecated None option in the
2363 args tuple returned by __reduce__().
2364
Brett Cannon84667c02004-12-07 03:25:18 +00002365- optparse now optionally imports gettext. This allows its use in setup.py.
2366
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002367- the pickle module no longer uses the deprecated bin parameter.
2368
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002369- the shelve module no longer uses the deprecated binary parameter.
2370
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002371- the pstats module no longer uses the deprecated ignore() method.
2372
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002373- the filecmp module no longer uses the deprecated use_statcache argument.
2374
Raymond Hettinger664347b2004-12-04 21:21:53 +00002375- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2376 extended or overridden by subclasses. Formerly, the subclassed method would
2377 be ignored by the rest of the module. (Bug #1078905).
2378
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002379- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002380 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002381
Walter Dörwald36733692004-12-22 12:50:50 +00002382- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2383 once when a size argument is given. This prevents a buffer overflow in the
2384 tokenizer with very long source lines.
2385
Barry Warsaw538561e2006-01-01 21:48:54 +00002386- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2387 immediately after creating the object, without any intervening
2388 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002389
Skip Montanaro05885812005-01-16 20:48:27 +00002390- The reconvert.quote function can now emit triple-quoted strings. The
2391 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002392
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002393- ``UserString.MutableString`` now supports negative indices in
2394 ``__setitem__`` and ``__delitem__``
2395
Greg Ward40407942005-03-05 02:53:17 +00002396- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2397 correctly.
2398
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002399- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2400 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2401 character even if the user has passed a size parameter to get a proper
2402 line ending. Remove the special handling of a "\r\n" that has been split
2403 between two lines.
2404
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002405- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2406 about illegal code points. The codec now supports PEP 293 style error
2407 handlers.
2408
Walter Dörwald78a78b02005-09-01 12:04:29 +00002409- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002410 from the input stream, so that the output is a byte string in the correct
2411 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002412
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002413- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2414 considering it exactly like a '*'.
2415
Walter Dörwald007f8df2005-10-09 19:42:27 +00002416- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2417 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002418
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002419- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2420
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002421- Patch #1413711: Certain patterns of differences were making difflib
2422 touch the recursion limit.
2423
Walter Dörwald58917a62006-03-31 15:26:22 +00002424- Bug #947906: An object oriented interface has been added to the calendar
2425 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002426 called as a script (e.g. via ``python -mcalendar``). Localized month and
2427 weekday names can be ouput (even if an exotic encoding is used) using
2428 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002429

2432
Neal Norwitz602d3392006-03-31 08:21:40 +00002433- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2434 by using -mieee gcc option.
2435

2437
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002438- Build support for Win64-AMD64 was added.
2439
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002440- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2441
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002442- Patch #881820: look for openpty and forkpty also in libbsd.
2443
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002444- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2445 The zlib module is now builtin on Windows.
2446
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002447- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2448
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002449- Bug #1189330: configure did not correctly determine the necessary
2450 value of LINKCC if python was built with GCC 4.0.
2451
Trent Mick8321b422005-07-26 02:29:21 +00002452- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2453 vulnerability in zlib 1.2.1 and 1.2.2.
2454
Brett Cannon08cd5982005-04-24 22:26:38 +00002455- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2456 flags that change binary compatibility. Changes were also made to
2457 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002458 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002459
Bob Ippolitoed233462005-03-29 13:47:59 +00002460- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2461 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2462 no longer exists). This configure patch makes things right.
2463
Martin v. Löwise2713be2005-03-08 15:03:08 +00002464- Bug #1158607: Build with --disable-unicode again.
2465
Brett Cannon46d96232005-02-16 00:07:19 +00002466- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2467 defined. Discovered as a result of not being able to build on OS X.
2468
Brett Cannon516592f2004-12-07 00:42:59 +00002469- setup.py now uses the directories specified in LDFLAGS using the -L option
2470 and in CPPFLAGS using the -I option for adding library and include
2471 directories, respectively, for compiling extension modules against. This has
2472 led to the core being compiled using the values in CPPFLAGS. It also removes
2473 the need for the special-casing of both DarwinPorts and Fink for darwin since
2474 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2475 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2476 Fink, ``-I/opt/local/include`` for DarwinPorts).
2477
Brett Cannon43802422005-02-10 20:48:03 +00002478- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2479 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2480 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2481 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002483C API
2484-----
2485
Tim Petersc9d78aa2006-03-26 23:27:58 +00002486- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2487 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2488 is obtained via the ``PyObject_`` family, it must be released via the
2489 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2490 always been officially true, but when Python's small-object allocator was
2491 introduced, an attempt was made to cater to a few extension modules
2492 discovered at the time that obtained memory via ``PyObject_New`` but
2493 released it via ``PyMem_DEL``. It's years later, and if such code still
2494 exists it will fail now (probably with segfaults, but calling wrong
2495 low-level memory management functions can yield many symptoms).
2496
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002497- Added a C API for set and frozenset objects.
2498
Raymond Hettinger66517482004-12-03 11:45:13 +00002499- Removed PyRange_New().
2500
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002501- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2502 mapping argument now. This string is used as a mapping table. Byte values
2503 greater than the length of the string and 0xFFFE are treated as undefined
2504 mappings.

2564 vimrc to it (was previous up a level).
2565
Georg Brandl56897312005-08-24 18:32:30 +00002566- Added two new files to Tools/scripts: pysource.py, which recursively
