Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000319- The return tuple from str.rpartition(sep) is (tail, sep, head) where
320 head is the original string if sep was not found.
321
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000322- Bug #1520864: unpacking singleton tuples in list comprehensions and
323 generator expressions (x for x, in ... ) works again. Fixing this problem
324 required changing the .pyc magic number. This means that .pyc files
325 generated before 2.5c2 will be regenerated.

425Core and builtins
426-----------------
427
Neal Norwitz24b6f202006-09-05 04:43:56 +0000428- Fix infinite recursion when subclassing long and overriding __hash__.
429
430- Fix concatenation (+=) of long strings.
431
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000432- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000433 compared equal or unequal to a string and a UnicodeDecodeError
434 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000435
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000436 Instead, the equal (==) and unequal (!=) comparison operators will
437 now issue a UnicodeWarning and interpret the two objects as
438 unequal. The UnicodeWarning can be filtered as desired using
439 the warning framework, e.g. silenced completely, turned into an
440 exception, logged, etc.
441
442 Note that compare operators other than equal and unequal will still
443 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000444
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000445- Fix segfault when doing string formatting on subclasses of long.
446
447- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
448 with new-style classes.
449
450- Fix bug related to __len__ functions returning negative values with
451 classic classes.
452
453- Patch #1538606, Fix __index__() clipping. There were some problems
454 discovered with the API and how integers that didn't fit into Py_ssize_t
455 were handled. This patch attempts to provide enough alternatives
456 to effectively use __index__.
457
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000458- Bug #1536021: __hash__ may now return long int; the final hash
459 value is obtained by invoking hash on the long int.
460
Thomas Hellerab1049c2006-08-08 17:37:00 +0000461- Bug #1536786: buffer comparison could emit a RuntimeWarning.

Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000463- Bug #1535165: fixed a segfault in input() and raw_input() when
464 sys.stdin is closed.
465
Thomas Heller74d36f02006-08-04 18:17:40 +0000466- On Windows, the PyErr_Warn function is now exported from
467 the Python dll again.
468
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000469- Bug #1191458: tracing over for loops now produces a line event
470 on each iteration. Fixing this problem required changing the .pyc
471 magic number. This means that .pyc files generated before 2.5c1
472 will be regenerated.
473
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000474- Bug #1333982: string/number constants were inappropriately stored
475 in the byte code and co_consts even if they were not used, ie
476 immediately popped off the stack.
477
Georg Brandle9462c72006-08-04 18:03:37 +0000478- Fixed a reference-counting problem in property().

481Library
482-------
483
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000484- Fix a bug in the ``compiler`` package that caused invalid code to be
485 generated for generator expressions.
486
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000487- The distutils version has been changed to 2.5.0. The change to
488 keep it programmatically in sync with the Python version running
489 the code (introduced in 2.5b3) has been reverted. It will continue
490 to be maintained manually as static string literal.
491
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000492- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000493 and this cannot be converted to the required C type, an exception is
494 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000495 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000496
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000497- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000498 an exception.
499
Tim Peterscbdd3502006-09-05 01:47:53 +0000500- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000501 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000502 workarounds for clocks with low resolution, to stop the code yielding
503 duplicate UUIDs.
504
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000505- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
506 before raising SystemExit, allowing IDLE to honor quit() and exit().
507
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000508- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
509
Georg Brandl7a1af772006-08-14 21:55:28 +0000510- Patch #1536071: trace.py should now find the full module name of a
511 file correctly even on Windows.
512
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000513- logging's atexit hook now runs even if the rest of the module has
514 already been cleaned up.
515
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000516- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000517
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000518- Bug #1531405, format_exception no longer raises an exception if
519 str(exception) raised an exception.
520
Neil Schemenauer06ded092006-08-04 16:20:30 +0000521- Fix a bug in the ``compiler`` package that caused invalid code to be
522 generated for nested functions.

533 raises the correct exceptions.
534
Thomas Heller1ce433e2006-08-14 16:20:04 +0000535- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
536 '-no-stack-protector' compiler flag for OpenBSD has been removed.
537
Thomas Heller86720042006-08-14 11:17:48 +0000538- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
539 uses the _as_parameter_ attribute when objects are passed to foreign
540 function calls. The ctypes version number was changed to 1.0.1.
541
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000542- Bug #1530559, struct.pack raises TypeError where it used to convert.
543 Passing float arguments to struct.pack when integers are expected
544 now triggers a DeprecationWarning.

594Core and builtins
595-----------------
596
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000597- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000598 returned a long (see PEP 353).
599
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000600- Bug #1515471: string.replace() accepts character buffers again.
601
Neal Norwitz07aadb12006-07-30 06:55:48 +0000602- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
603 This provides the proper warning for struct.pack().
604 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
605
Neal Norwitz0d62a062006-07-30 06:53:31 +0000606- Patch #1531113: Fix augmented assignment with yield expressions.
607 Also fix a SystemError when trying to assign to yield expressions.
608
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000609- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
610 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
611 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
612 excessive filesystem operations during imports.
613
Tim Petersbc24eee2006-07-27 01:14:53 +0000614- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
615 operations on signed longs that are formally undefined by C.
616 Unfortunately, at least one compiler now cares about that, so complicated
617 the code to make that compiler happy again.
618
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000619- Bug #1524310: Properly report errors from FindNextFile in os.listdir.

625
Neal Norwitze7563102006-07-17 01:00:16 +0000626- Fix warnings reported by Klocwork's static analysis tool.
627
Neal Norwitz84be93b2006-07-16 01:50:38 +0000628- Bug #1512814, Fix incorrect lineno's when code within a function
629 had more than 255 blank lines.
630
Georg Brandl9dceedb2006-07-12 15:31:17 +0000631- Patch #1521179: Python now accepts the standard options ``--help`` and
632 ``--version`` as well as ``/?`` on Windows.
633
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000634- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000635 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000636 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000637
Tim Peters112aad32006-07-19 00:03:19 +0000638- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000639 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000640 new ``sys._current_frames()`` returns a dictionary with one entry,
641 mapping the faux "thread id" 0 to the current frame.
642
Ronald Oussoren3075e162006-07-25 20:28:55 +0000643- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

647-------
648
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000649- Correction of patch #1455898: In the mbcs decoder, set final=False
650 for stream decoder, but final=True for the decode function.
651
Georg Brandl07fec3a2006-08-01 18:49:24 +0000652- os.urandom no longer masks unrelated exceptions like SystemExit or
653 KeyboardInterrupt.
654
Tim Peters4643c2f2006-08-10 22:45:34 +0000655- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000656 shutil.copytree on Windows
657
Georg Brandle34ac7c2006-07-30 11:07:23 +0000658- Bug #1002398: The documentation for os.path.sameopenfile now correctly
659 refers to file descriptors, not file objects.
660
Tim Peterscbdd3502006-09-05 01:47:53 +0000661- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000662 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000663 #1513611, and probably others.
664
Georg Brandledd9b0d2006-07-29 09:33:26 +0000665- Bug #1441397: The compiler module now recognizes module and function
666 docstrings correctly as it did in Python 2.4.
667
Tim Peters6f681472006-07-27 23:44:37 +0000668- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
669 lost that tests are sorted by name before being run. This rarely
670 matters for well-written tests, but can create baffling symptoms if
671 side effects from one test to the next affect outcomes. ``DocTestFinder``
672 has been changed to sort the list of tests it returns.
673
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000674- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000675 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000676

Georg Brandldb232dc2006-08-20 13:15:43 +0000679- Bug #1459963: urllib and urllib2 now normalize HTTP header names with

Georg Brandl0619a322006-07-26 07:40:17 +0000681
Georg Brandlcf0c1722006-07-26 07:23:32 +0000682- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
683 to recursive calls and call it with the failing package name.
684
Martin v. Löwis0b483032006-07-25 09:53:12 +0000685- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
686
Georg Brandlc13c34c2006-07-24 14:09:56 +0000687- Patch #1515343: Fix printing of deprecated string exceptions with a
688 value in the traceback module.
689
Greg Ward48fae7a2006-07-23 16:05:51 +0000690- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
691
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000692- Patch #1524429: Use repr() instead of backticks in Tkinter again.
693
Brett Cannoncaebe222006-07-18 04:41:36 +0000694- Bug #1520914: Change time.strftime() to accept a zero for any position in its
695 argument tuple. For arguments where zero is illegal, the value is forced to
696 the minimum value that is correct. This is to support an undocumented but
697 common way people used to fill in inconsequential information in the time
698 tuple pre-2.4.
699
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000700- Patch #1220874: Update the binhex module for Mach-O.
701
Barry Warsawb110bad2006-07-21 14:51:07 +0000702- The email package has improved RFC 2231 support, specifically for
703 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
704 (name*0=<blah>) parameter continuations. This may change the types of
705 values returned from email.message.Message.get_param() and friends.
706 Specifically in some cases where non-encoded continuations were used,
707 get_param() used to return a 3-tuple of (None, None, string) whereas now it
708 will just return the string (since non-encoded continuations don't have
709 charset and language parts).
710
711 Also, whereas % values were decoded in all parameter continuations, they are
712 now only decoded in encoded parameter parts.
713
Ronald Oussoren3075e162006-07-25 20:28:55 +0000714- Bug #1517990: IDLE keybindings on MacOS X now work correctly
715
716- Bug #1517996: IDLE now longer shows the default Tk menu when a
717 path browser, class browser or debugger is the frontmost window on MacOS X
718
Barry Warsaw00decd72006-07-27 23:43:15 +0000719- Patch #1520294: Support for getset and member descriptors in types.py,
720 inspect.py, and pydoc.py. Specifically, this allows for querying the type
721 of an object against these built-in types and more importantly, for getting
722 their docstrings printed in the interactive interpreter's help() function.

726-----------------
727
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000728- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
729 a socket operation on a socket with a timeout, the exception will be
730 caught correctly. Previously, the exception was not caught.
731
Thomas Heller1393d6a2006-07-28 21:43:20 +0000732- Patch #1529514: The _ctypes extension is now compiled on more
733 openbsd target platforms.
734
Tim Peters9cab5932006-07-28 00:30:00 +0000735- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
736 a memory leak, affecting pickles and deep copies.
737
Tim Petersbc24eee2006-07-27 01:14:53 +0000738- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000739 Paul Eggert.
740
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000741- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
742
Thomas Hellerce049a02006-07-14 17:51:14 +0000743- Patch #1521817: Index range checking on ctypes arrays containing
744 exactly one element enabled again. This allows iterating over these
745 arrays, without the need to check the array size before.
746
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000747- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000748 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000749 /dev/null in certain cases; this is now fixed.
750
Thomas Heller47d7a062006-07-12 08:43:47 +0000751- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
752 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000753
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000754- Because of a misspelled preprocessor symbol, ctypes was always
755 compiled without thread support; this is now fixed.
756
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000757- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
758 methods now allow their database parameter to be None as the
759 sleepycat API allows.
760
Matt Flemingec926502006-07-28 11:27:27 +0000761- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
762 bluetooth API compared with Linux and FreeBSD.
763
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000764Tests
765-----
766
767- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
768 how long the test file should take to play. Now accepts taking 2.93 secs
769 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
770
Georg Brandl4793aa32006-07-28 18:31:39 +0000771- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
772 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
773 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +0000780Mac
781---
782
783- PythonLauncher now works correctly when the path to the script contains
784 characters that are treated specially by the shell (such as quotes).
785
786- Bug #1527397: PythonLauncher now launches scripts with the working directory
787 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000788 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000789 expect.

798-----------------
799
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000800- Bug #1441486: The literal representation of -(sys.maxint - 1)
801 again evaluates to a int object, not a long.
802
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000803- Bug #1501934: The scope of global variables that are locally assigned
804 using augmented assignment is now correctly determined.
805
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000806- Bug #927248: Recursive method-wrapper objects can now safely
807 be released.
808
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000809- Bug #1417699: Reject locale-specific decimal point in float()
810 and atof().
811
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000812- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
813 omit a default "error" argument for NULL pointer. This allows
814 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000815
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000816- Bug #1519018: 'as' is now validated properly in import statements.
817
Neal Norwitz28746ab2006-07-09 22:14:42 +0000818- On 64 bit systems, int literals that use less than 64 bits are
819 now ints rather than longs.
820
Neal Norwitzed657552006-07-10 00:04:44 +0000821- Bug #1512814, Fix incorrect lineno's when code at module scope
822 started after line 256.
823
Tim Peters32a83612006-07-10 21:08:24 +0000824- New function ``sys._current_frames()`` returns a dict mapping thread
825 id to topmost thread stack frame. This is for expert use, and is
826 especially useful for debugging application deadlocks. The functionality
827 was previously available in Fazal Majid's ``threadframe`` extension
828 module, but it wasn't possible to do this in a wholly threadsafe way from
829 an extension.

838
Tim Peters32a83612006-07-10 21:08:24 +0000839- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000840 environment variable to be set in order to the SDK environment
841 for finding the compiler, include files, etc.

846
Thomas Woutersadd19112006-07-05 11:03:49 +0000847- string.Template() now correctly handles tuple-values. Previously,
848 multi-value tuples would raise an exception and single-value tuples would
849 be treated as the value they contain, instead.
850
Martin v. Löwisede77f52006-07-03 13:01:35 +0000851- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

858 degrees and radians.
859
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000860- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000861 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000862
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000863- Bug #1514703: Only setup canvas window in turtle when the canvas
864 is created.
865
Martin v. Löwis7596e832006-07-01 15:33:37 +0000866- Bug #1513223: .close() of a _socketobj now releases the underlying
867 socket again, which then gets closed as it becomes unreferenced.

870 attribute values.
871
872- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
873 sgmllib ('[' and ']' were not accepted).
874
Georg Brandl1be63af2006-06-28 20:23:25 +0000875- Fix a bug in the turtle module's end_fill function.
876
Brett Cannon53ab5b72006-06-22 16:49:14 +0000877- Bug #1510580: The 'warnings' module improperly required that a Warning
878 category be either a types.ClassType and a subclass of Warning. The proper
879 check is just that it is a subclass with Warning as the documentation states.
880
Georg Brandlad29e632006-06-21 17:45:17 +0000881- The compiler module now correctly compiles the new try-except-finally
882 statement (bug #1509132).
883
Neal Norwitz60373cd2006-06-22 06:30:50 +0000884- The wsgiref package is now installed properly on Unix.
885
Vinay Sajip28e57612006-07-01 10:45:20 +0000886- A bug was fixed in logging.config.fileConfig() which caused a crash on
887 shutdown when fileConfig() was called multiple times.
888
Gerhard Häring762fbd32006-07-02 17:48:30 +0000889- The sqlite3 module did cut off data from the SQLite database at the first
890 null character before sending it to a custom converter. This has been fixed
891 now.

Tim Peters112aad32006-07-19 00:03:19 +0000896- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
897 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
898 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000899
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000900- Assigning None to pointer type fields in ctypes structures possible
901 overwrote the wrong fields, this is fixed now.
902
903- Fixed a segfault in _ctypes when ctypes.wintypes were imported
904 on non-Windows platforms.
905
906- Bug #1518190: The ctypes.c_void_p constructor now accepts any
907 integer or long, without range checking.
908
909- Patch #1517790: It is now possible to use custom objects in the ctypes
910 foreign function argtypes sequence as long as they provide a from_param
911 method, no longer is it required that the object is a ctypes type.
912
913- The '_ctypes' extension module now works when Python is configured
914 with the --without-threads option.
915
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000916- Bug #1513646: os.access on Windows now correctly determines write
917 access, again.
918
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000919- Bug #1512695: cPickle.loads could crash if it was interrupted with

931
Tim Peters32a83612006-07-10 21:08:24 +0000932- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000933 Previously, the slight difference could cause compilation errors of the
934 'zlib' module on systems with more than one version of zlib.
935
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000936- The MSI compileall step was fixed to also support a TARGETDIR

Anthony Baxter51bcb682006-04-05 14:51:42 +0000966
967Core and builtins
968-----------------
969
Georg Brandla56b9152006-06-19 06:35:54 +0000970- Patch #1507676: Error messages returned by invalid abstract object operations
971 (such as iterating over an integer) have been improved and now include the
972 type of the offending object to help with debugging.
973
Brett Cannonea3912b2006-06-13 21:46:41 +0000974- Bug #992017: A classic class that defined a __coerce__() method that returned
975 its arguments swapped would infinitely recurse and segfault the interpreter.
976
Neal Norwitz909eb122006-06-12 02:13:21 +0000977- Fix the socket tests so they can be run concurrently.
978
Neal Norwitzb9845e72006-06-12 02:11:18 +0000979- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000980 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000981
Brett Cannon22565aa2006-06-09 22:31:23 +0000982- Bug #532646: object.__call__() will continue looking for the __call__
983 attribute on objects until one without one is found. This leads to recursion
984 when you take a class and set its __call__ attribute to an instance of the
985 class. Originally fixed for classic classes, but this fix is for new-style.
986 Removes the infinite_rec_3 crasher.
987
Georg Brandl24250812006-06-09 18:45:48 +0000988- The string and unicode methods startswith() and endswith() now accept
989 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
990
Brett Cannonde3b0522006-06-08 17:00:45 +0000991- Buffer objects, at the C level, never used the char buffer
992 implementation even when the char buffer for the wrapped object was
993 explicitly requested (originally returned the read or write buffer).
994 Now a TypeError is raised if the char buffer is not present but is
995 requested.
996
Georg Brandlddbaa662006-06-04 21:56:52 +0000997- Patch #1346214: Statements like "if 0: suite" are now again optimized
998 away like they were in Python 2.4.
999
Georg Brandlb7c8f542006-05-27 12:30:25 +00001000- Builtin exceptions are now full-blown new-style classes instead of
1001 instances pretending to be classes, which speeds up exception handling
1002 by about 80% in comparison to 2.5a2.
1003
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001004- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1005 Unicode 4.1.
1006
Georg Brandlf4ef1162006-05-26 18:03:31 +00001007- Patch #921466: sys.path_importer_cache is now used to cache valid and
1008 invalid file paths for the built-in import machinery which leads to
1009 fewer open calls on startup.
1010
Tim Peters696cf432006-05-24 21:10:40 +00001011- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1012 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1013 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1014 the number of input digits (it was and remains linear-time for bases
1015 2, 4, 8, 16 and 32).
1016
Tim Petersb713ec22006-05-23 18:45:30 +00001017- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1018 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1019 an integer close to ``sys.maxint``. This was repaired by patch
1020 #1335972, which also gives a nice speedup.
1021
Richard Jonescebbefc2006-05-23 18:28:17 +00001022- Patch #1337051: reduced size of frame objects.
1023
1024- PyErr_NewException now accepts a tuple of base classes as its
1025 "base" parameter.
1026
Richard Jones7c88dcc2006-05-23 10:37:38 +00001027- Patch #876206: function call speedup by retaining allocated frame
1028 objects.
1029
Georg Brandl7b90e162006-05-18 07:01:27 +00001030- Bug #1462152: file() now checks more thoroughly for invalid mode
1031 strings and removes a possible "U" before passing the mode to the
1032 C library function.
1033
Neal Norwitz1004a532006-05-15 07:17:23 +00001034- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1035
Neal Norwitz373f0a72006-05-15 07:04:36 +00001036- Bug #1487966: Fix SystemError with conditional expression in assignment
1037
Martin v. Löwis879768d2006-05-11 13:28:43 +00001038- WindowsError now has two error code attributes: errno, which carries
1039 the error values from errno.h, and winerror, which carries the error
1040 values from winerror.h. Previous versions put the winerror.h values
1041 (from GetLastError()) into the errno attribute.
1042
Martin v. Löwis77736712006-05-04 05:51:03 +00001043- Patch #1475845: Raise IndentationError for unexpected indent.
1044
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001045- Patch #1479181: split open() and file() from being aliases for each other.
1046
Tim Peters44bd9862006-06-01 13:49:23 +00001047- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1048 methods were always silently ignored by dictionaries when comparing keys.
1049 They are now passed through (except when using the C API function
1050 ``PyDict_GetItem()``, whose semantics did not change).
1051
1052- Bug #1456209: In some obscure cases it was possible for a class with a
1053 custom ``__eq__()`` method to confuse dict internals when class instances
1054 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1055 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001057Extension Modules
1058-----------------
1059
Trent Mick960a3f82006-06-28 20:30:41 +00001060- Bug #1295808: expat symbols should be namespaced in pyexpat
1061
1062- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1063
Brett Cannon6ee7d012006-06-08 16:23:04 +00001064- Change binascii.hexlify to accept a read-only buffer instead of only a char
1065 buffer and actually follow its documentation.
1066
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001067- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1068
Nick Coghlanc649ec52006-05-29 12:43:05 +00001069- Patch #1478788 (modified version): The functional extension module has
1070 been renamed to _functools and a functools Python wrapper module added.
1071 This provides a home for additional function related utilities that are
1072 not specifically about functional programming. See PEP 309.
1073
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001074- Patch #1493701: performance enhancements for struct module.
1075
Georg Brandl378d5922006-05-17 14:26:50 +00001076- Patch #1490224: time.altzone is now set correctly on Cygwin.
1077
Georg Brandl8d3342b2006-05-16 07:38:27 +00001078- Patch #1435422: zlib's compress and decompress objects now have a
1079 copy() method.
1080
Andrew MacIntyre92913322006-06-13 15:04:24 +00001081- Patch #1454481: thread stack size is now tunable at runtime for thread
1082 enabled builds on Windows and systems with Posix threads support.
1083
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001084- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1085 (up to the system limit of 32K characters).
1086
1087- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1088 As a result, these functions now raise WindowsError instead of OSError.
1089
Tim Peters7a822da2006-05-25 21:50:17 +00001090- ``time.clock()`` on Win64 should use the high-performance Windows
1091 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1092 Windows platforms).
1093
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001094- Calling Tk_Init twice is refused if the first call failed as that
1095 may deadlock.
1096
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001097- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1098 accept it without potentially using an uninitialized pointer.
1099
1100- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1101 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1102 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001103
Gregory P. Smith372b5832006-06-05 18:48:21 +00001104- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001105 [pybsddb project SF patch number 1466734]
1106
Gregory P. Smith372b5832006-06-05 18:48:21 +00001107- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1108 parameter is supplied. [SF pybsddb bug #1477863]
1109
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001110- bsddb: the __len__ method of a DB object has been fixed to return correct
1111 results. It could previously incorrectly return 0 in some cases.
1112 Fixes SF bug 1493322 (pybsddb bug 1184012).
1113
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001114- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1115 aborts the db transaction safely when a modifier callback fails.
1116 Fixes SF python patch/bug #1408584.
1117
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001118- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001119 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001120 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1121 database calls that would previously deadlock. [SF python bug #775414]
1122
Vinay Sajip28e57612006-07-01 10:45:20 +00001123- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001124
Walter Dörwald4994d952006-06-19 08:07:50 +00001125- Patch #1506645: add Python wrappers for the curses functions
1126 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001127
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001128Library
1129-------
1130
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001131- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1132 functions.
1133
Martin v. Löwis3798da02006-06-17 18:44:27 +00001134- Patch #812986: Update turtle output even if not tracing.
1135
Vinay Sajip28e57612006-07-01 10:45:20 +00001136- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001137 Tkinter.BaseWidget.
1138
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001139- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1140
Martin v. Löwis337487e2006-06-17 09:15:14 +00001141- Patch #763580: Add name and value arguments to Tkinter variable
1142 classes.
1143
Georg Brandl83cc0d02006-06-14 08:50:03 +00001144- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1145 mime.types file for determining MIME types.
1146
Georg Brandl2605ca82006-06-14 06:08:31 +00001147- Bug #1339007: Shelf objects now don't raise an exception in their
1148 __del__ method when initialization failed.
1149
Martin v. Löwisd8251432006-06-14 05:21:04 +00001150- Patch #1455898: The MBCS codec now supports the incremental mode for
1151 double-byte encodings.
1152
Tim Peters43898b42006-06-14 04:09:25 +00001153- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1154 guarantee that adjacent triples in the return list always describe
1155 non-adjacent blocks. Previously, a pair of matching blocks could end
1156 up being described by multiple adjacent triples that formed a partition
1157 of the matching pair.
1158
Greg Ward0e0c9f42006-06-11 16:24:11 +00001159- Bug #1498146: fix optparse to handle Unicode strings in option help,
1160 description, and epilog.
1161
Greg Wardd1c797e2006-06-11 14:42:41 +00001162- Bug #1366250: minor optparse documentation error.
1163
Greg Ward7f547402006-06-11 00:40:49 +00001164- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1165 clarify docs.
1166
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001167- The wsgiref package has been added to the standard library.
1168
Nick Coghlan676725d2006-06-08 13:54:49 +00001169- The functions update_wrapper() and wraps() have been added to the functools
1170 module. These make it easier to copy relevant metadata from the original
1171 function when writing wrapper functions.
1172
Tim Petersd6a9eef2006-06-05 01:48:21 +00001173- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1174 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001175
Martin v. Löwis3f767792006-06-04 19:36:28 +00001176- Patch #1359618: Speed up charmap encoder by using a trie structure
1177 for lookup.
1178
Tim Petersd609b1a2006-06-02 23:22:51 +00001179- The functions in the ``pprint`` module now sort dictionaries by key
1180 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1181 if and only if its display required more than one line, although that
1182 wasn't documented. The new behavior increases predictability; e.g.,
1183 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1184
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001185- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1186 (thanks for J. J. Lee).
1187
Georg Brandl2b330372006-05-28 20:23:12 +00001188- Patch #1496206: improve urllib2 handling of passwords with respect to
1189 default HTTP and HTTPS ports.
1190
George Yoshidaf3c65de2006-05-28 16:39:09 +00001191- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1192
Bob Ippolito7298f272006-05-23 18:43:47 +00001193- Patch #1281707: speed up gzip.readline.
1194
Georg Brandlb89316f2006-05-17 15:51:16 +00001195- Patch #1180296: Two new functions were added to the locale module:
1196 format_string() to get the effect of "format % items" but locale-aware,
1197 and currency() to format a monetary number with currency sign.
1198
Georg Brandle3a25832006-05-17 14:56:04 +00001199- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1200 and several features added, such as speed and geometry control.
1201
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001202- Patch #1488881: add support for external file objects in bz2 compressed
1203 tarfiles.
1204
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001205- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1206 stdout arguments, making it possible to redirect input and output
1207 for remote debugging.

1211 GNU LONGNAME extension.
1212
1213- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1214 new flag when ``name`` is already the name of an option flag.
1215

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001255What's New in Python 2.5 alpha 2?
1256=================================
1257
1258*Release date: 27-APR-2006*
1259
1260Core and builtins
1261-----------------
1262
Thomas Heller1b046642006-04-18 18:51:06 +00001263- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1264 by converting these apis from macros into exported functions again:
1265
1266 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1267 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1268 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1269 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1270 PyRun_String Py_CompileString
1271
Martin v. Löwis45294a92006-04-18 06:24:08 +00001272- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1273
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001274- All uses of PyStructSequence_InitType have been changed to initialize
1275 the type objects only once, even if the interpreter is initialized
1276 multiple times.
1277
Neal Norwitz61546162006-04-14 05:20:28 +00001278- Bug #1454485, array.array('u') could crash the interpreter. This was
1279 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1280 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1281
1282- Py_UNICODE is unsigned. It was always documented as unsigned, but
1283 due to a bug had a signed value in previous versions.
1284
Tim Peters3a5e8b12006-04-11 01:44:07 +00001285- Patch #837242: ``id()`` of any Python object always gives a positive
1286 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1287 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001288 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001289 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001290
Tim Peters3a5e8b12006-04-11 01:44:07 +00001291 def __hash__(self):
1292 return id(self) # WRONG
1293
1294 because a hash result must be a (short) Python int but it was always
1295 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001296 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001297 was always usable as a hash value before this patch. That's no longer
1298 necessarily so.
1299
1300- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001301 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001302 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001303 #1454844)
1304
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001305- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1306 involving generators that have paused outside of any ``try`` or ``with``
1307 blocks. (In 2.5a1, a paused generator that was part of a reference
1308 cycle could not be garbage collected, regardless of whether it was
1309 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001310
Anthony Baxter51bcb682006-04-05 14:51:42 +00001311Extension Modules
1312-----------------
1313
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001314- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1315 is a macro.
1316
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001317- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1318 fails with an error condition.
1319
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001320- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1321
1322- Bug #1117761: bsddb.*open() no longer raises an exception when using
1323 the cachesize parameter.
1324
1325- Bug #1149413: bsddb.*open() no longer raises an exception when using
1326 a temporary db (file=None) with the 'n' flag to truncate on open.
1327
1328- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1329 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001330
Armin Rigoa9017c32006-04-19 11:50:27 +00001331- Patch #1062014: AF_UNIX sockets under Linux have a special
1332 abstract namespace that is now fully supported.
1333
Anthony Baxter51bcb682006-04-05 14:51:42 +00001334Library
1335-------
1336
Peter Astrand7d1d4362006-07-14 14:04:45 +00001337- Bug #1223937: subprocess.CalledProcessError reports the exit status
1338 of the process using the returncode attribute, instead of
1339 abusing errno.
1340
Tim Peters711bf302006-04-25 03:31:36 +00001341- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1342 a doctest to be skipped (the code is not run, and the expected output
1343 or exception is ignored).
1344
Nick Coghlanda2268f2006-04-24 04:37:15 +00001345- Fixed contextlib.nested to cope with exceptions being raised and
1346 caught inside exit handlers.
1347
Greg Wardab05edc2006-04-23 03:47:58 +00001348- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1349 hex, octal, or binary; add ``append_const`` action; keep going if
1350 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1351 added ``epilog`` for better help generation).
1352
Tim Peters21fbd572006-04-21 21:18:10 +00001353- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1354 called from a thread spawned as a side effect of importing a module.
1355
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001356- The pydoc module now supports documenting packages contained in
1357 .zip or .egg files.
1358
1359- The pkgutil module now has several new utility functions, such
1360 as ``walk_packages()`` to support working with packages that are either
1361 in the filesystem or zip files.
1362
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001363- The mailbox module can now modify and delete messages from
1364 mailboxes, in addition to simply reading them. Thanks to Gregory
1365 K. Johnson for writing the code, and to the 2005 Google Summer of
1366 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001367
Tim Petersc7605f22006-04-17 21:12:33 +00001368- The ``__del__`` method of class ``local`` in module ``_threading_local``
1369 returned before accomplishing any of its intended cleanup.
1370
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001371- Patch #790710: Add breakpoint command lists in pdb.
1372
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001373- Patch #1063914: Add Tkinter.Misc.clipboard_get().
1374
Martin v. Löwis4b501e62006-04-15 08:41:11 +00001375- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1376
Anthony Baxtere29002c2006-04-12 12:07:31 +00001377- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1378 Windows. Bug #1469163.
1379
Phillip J. Eby47032112006-04-11 01:07:43 +00001380- The warnings, linecache, inspect, traceback, site, and doctest modules
1381 were updated to work correctly with modules imported from zipfiles or
1382 via other PEP 302 __loader__ objects.
1383
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001384- Patch #1467770: Reduce usage of subprocess._active to processes which
1385 the application hasn't waited on.
1386
Martin v. Löwisb04dee92006-04-10 08:34:21 +00001387- Patch #1462222: Fix Tix.Grid.
1388
Neal Norwitza31bf182006-04-09 03:35:43 +00001389- Fix exception when doing glob.glob('anything*/')
1390
Skip Montanaro262fb922006-04-21 02:31:07 +00001391- The pstats.Stats class accepts an optional stream keyword argument to
1392 direct output to an alternate file-like object.
1393
Anthony Baxter51bcb682006-04-05 14:51:42 +00001394Build
1395-----
1396
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001397- The Makefile now has a reindent target, which runs reindent.py on
1398 the library.
1399
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001400- Patch #1470875: Building Python with MS Free Compiler
1401
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001402- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001403
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001404- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1405 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001406 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001407 CXX from --with-cxx-main, see description in README.
1408
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001409- Patch #1429775: Link extension modules with the shared libpython.
1410
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001411- Fixed a libffi build problem on MIPS systems.
1412
Tim Peters8931ff12006-05-13 23:28:20 +00001413- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1414 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1415 and "%zu" for unsigned integers of type ``size_t``.
1416
Anthony Baxter51bcb682006-04-05 14:51:42 +00001417Tests
1418-----
1419
Nick Coghlanda2268f2006-04-24 04:37:15 +00001420- test_contextlib now checks contextlib.nested can cope with exceptions
1421 being raised and caught inside exit handlers.
1422
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001423- test_cmd_line now checks operation of the -m and -c command switches
1424
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001425- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1426 it separately and by hand. It also wasn't cleaning up its changes to
1427 the current Decimal context.
1428
Thomas Woutersabd08882006-04-26 15:53:30 +00001429- regrtest.py now has a -M option to run tests that test the new limits of
1430 containers, on 64-bit architectures. Running these tests is only sensible
1431 on 64-bit machines with more than two gigabytes of memory. The argument
1432 passed is the maximum amount of memory for the tests to use.
1433
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001434Tools
1435-----
1436
1437- Added the Python benchmark suite pybench to the Tools/ directory;
1438 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001440Documentation
1441-------------
1442
Tim Petersb06d28c2006-05-12 01:57:59 +00001443- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1444
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001445- PEP 343: Added Context Types section to the library reference
1446 and attempted to bring other PEP 343 related documentation into
1447 line with the implementation and/or python-dev discussions.
1448
Tim Peters8dc73d22006-04-24 02:03:16 +00001449- Bug #1337990: clarified that ``doctest`` does not support examples
1450 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001453What's New in Python 2.5 alpha 1?
1454=================================
1455
Anthony Baxterebed3f62006-04-03 15:03:44 +00001456*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001457
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001458Core and builtins
1459-----------------
1460
Nick Coghlan43832302006-04-23 17:04:07 +00001461- PEP 338: -m command line switch now delegates to runpy.run_module
1462 allowing it to support modules in packages and zipfiles
1463
Martin v. Löwisc661b882006-04-20 04:54:23 +00001464- On Windows, .DLL is not an accepted file name extension for
1465 extension modules anymore; extensions are only found if they
1466 end in .PYD.
1467
Martin v. Löwisea62d252006-04-03 10:56:49 +00001468- Bug #1421664: sys.stderr.encoding is now set to the same value as
1469 sys.stdout.encoding.
1470
Neal Norwitz92e212f2006-04-03 04:48:37 +00001471- __import__ accepts keyword arguments.
1472
Georg Brandlccadf842006-03-31 18:54:53 +00001473- Patch #1460496: round() now accepts keyword arguments.
1474
Anthony Baxter262c00a2006-03-30 10:53:17 +00001475- Fixed bug #1459029 - unicode reprs were double-escaped.
1476
Hye-Shik Changd478f342006-03-23 12:32:36 +00001477- Patch #1396919: The system scope threads are reenabled on FreeBSD
1478 5.4 and later versions.
1479
Neal Norwitze98ccf62006-03-23 05:39:47 +00001480- Bug #1115379: Compiling a Unicode string with an encoding declaration
1481 now gives a SyntaxError.
1482
Georg Brandlabd1ff82006-03-18 07:59:59 +00001483- Previously, Python code had no easy way to access the contents of a
1484 cell object. Now, a ``cell_contents`` attribute has been added
1485 (closes patch #1170323).
1486
Tim Peterscf79aac2006-03-16 01:14:46 +00001487- Patch #1123430: Python's small-object allocator now returns an arena to
1488 the system ``free()`` when all memory within an arena becomes unused
1489 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1490 freed. Some applications will see a drop in virtual memory size now,
1491 especially long-running applications that, from time to time, temporarily
1492 use a large number of small objects. Note that when Python returns an
1493 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001494 platform C library will in turn return that memory to the operating system.
1495 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001496 appears to be effective at least on Microsoft C and gcc-based systems.
1497 Thanks to Evan Jones for hard work and patience.
1498
Georg Brandl533ff6f2006-03-08 18:09:27 +00001499- Patch #1434038: property() now uses the getter's docstring if there is
1500 no "doc" argument given. This makes it possible to legitimately use
1501 property() as a decorator to produce a read-only property.
1502
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001503- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1504 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1505 of requiring an int or long in slicing and a few other contexts, enabling
1506 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1507
Neal Norwitz995acdf2006-03-07 05:01:00 +00001508- Fixed various bugs reported by Coverity's Prevent tool.
1509
Brett Cannonbf364092006-03-01 04:25:17 +00001510- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1511 new exception base class, BaseException, which has a new message attribute.
1512 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1513 Raising a string exception now raises a DeprecationWarning.
1514
Thomas Woutersfb609f42006-02-28 16:37:25 +00001515- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1516 explicitly relative, using 'from .module import name' to mean 'from the same
1517 package as this module is in. Imports without dots still default to the
1518 old relative-then-absolute, unless 'from __future__ import
1519 absolute_import' is used.
1520
Brett Cannona7446e32006-02-27 23:39:10 +00001521- Properly check if 'warnings' raises an exception (usually when a filter set
1522 to "error" is triggered) when raising a warning for raising string
1523 exceptions.
1524
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001525- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001526 The name was removed from Include/code.h.
1527
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001528- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001529
Guido van Rossum1968ad32006-02-25 22:38:04 +00001530- Patch 1433928:
1531 - The copy module now "copies" function objects (as atomic objects).
1532 - dict.__getitem__ now looks for a __missing__ hook before raising
1533 KeyError.
1534
Tim Peters84ef21c2006-02-28 20:39:06 +00001535- PEP 343: with statement implemented. Needs ``from __future__ import
1536 with_statement``. Use of 'with' as a variable will generate a warning.
1537 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001538 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001539 The following objects have __context__ methods:
1540 - The built-in file type.
1541 - The thread.LockType type.
1542 - The following types defined by the threading module:
1543 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1544 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001545
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001546- Fix the encodings package codec search function to only search
1547 inside its own package. Fixes problem reported in patch #1433198.
1548
1549 Note: Codec packages should implement and register their own
1550 codec search function. PEP 100 has the details.
1551
Tim Peters9ea89d22006-06-04 03:26:02 +00001552- PEP 353: Using ``Py_ssize_t`` as the index type.
1553
1554- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1555 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1556 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1557 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1558 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001559
Neal Norwitzfc76d632006-01-10 06:03:13 +00001560- Patch #1400181, fix unicode string formatting to not use the locale.
1561 This is how string objects work. u'%f' could use , instead of .
1562 for the decimal point. Now both strings and unicode always use periods.
1563
Neal Norwitz671b9e32006-01-09 07:07:12 +00001564- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1565 configure would break checking curses.h.
1566
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001567- Bug #959576: The pwd module is now builtin. This allows Python to be
1568 built on UNIX platforms without $HOME set.
1569
Neal Norwitzc10978f2005-12-19 06:07:16 +00001570- Bug #1072182, fix some potential problems if characters are signed.
1571
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001572- Bug #889500, fix line number on SyntaxWarning for global declarations.
1573
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001574- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1575
Neal Norwitze7214a12005-12-18 05:03:17 +00001576- Support for converting hex strings to floats no longer works.
1577 This was not portable. float('0x3') now raises a ValueError.
1578
Barry Warsaw2a38a862005-12-18 01:27:35 +00001579- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001580 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001581 is now displayed in interactive prompt banner.
1582
Georg Brandlfa166682005-12-17 21:45:17 +00001583- Implementation of PEP 341 - Unification of try/except and try/finally.
1584 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001585 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001586
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001587- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1588 now encodes backslash correctly.
1589
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001590- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1591
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001592- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001593 and long longs.
1594
Neal Norwitz67715f02005-11-09 06:59:35 +00001595- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001596 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001597 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001598
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001599- Replaced most Unicode charmap codecs with new ones using the
1600 new Unicode translate string feature in the builtin charmap
1601 codec; the codecs were created from the mapping tables available
1602 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1603 encodings now include a mapping for the Apple logo)
1604
Tim Peterse3547fd2005-12-16 23:13:57 +00001605- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001606
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001607- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001608
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001609- A new AST parser implementation was completed. The abstract
1610 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001611 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001612
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001613- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001614 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1615
Neal Norwitz708e51a2005-10-03 04:48:15 +00001616- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1617
Neal Norwitz11bd1192005-10-03 00:54:56 +00001618- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1619 Provide a warning when a directory is passed on the command line.
1620
Neal Norwitz40d37812005-10-02 01:48:49 +00001621- Fix segfault with invalid coding.
1622
1623- SF bug #772896: unknown encoding results in MemoryError.
1624
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001625- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001626 supported a __len__() method which evaluated to False when the iterator
1627 was empty.
1628
Guido van Rossum630db602005-09-20 18:49:54 +00001629- On 64-bit platforms, when __len__() returns a value that cannot be
1630 represented as a C int, raise OverflowError.
1631
Skip Montanarof8948ca2005-09-19 03:54:46 +00001632- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001633 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001634
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001635- SF bug #893549: parsing keyword arguments was broken with a few format
1636 codes.
1637
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001638- Changes donated by Elemental Security to make it work on AIX 5.3
1639 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1640 bug #105470: test_pwd fails on 64bit system (Opteron).
1641
Guido van Rossum539c6622005-09-14 17:49:54 +00001642- Changes donated by Elemental Security to make it work on HP-UX 11 on
1643 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1644
Georg Brandl4550b8d2005-08-26 06:43:52 +00001645- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001646 (fixes bug #1119418).
1647
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001648- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1649
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001650- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1651 exceptions that cause a function to exit.
1652
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001653- The implementation of set() and frozenset() was revised to use its
1654 own internal data structure. Memory consumption is reduced by 1/3
1655 and there are modest speed-ups as well. The API is unchanged.
1656
Tim Petersde7990b2005-07-17 23:45:23 +00001657- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1658
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001659- SF bug #1229429: PyObject_CallMethod failed to decrement some
1660 reference counts in some error exit cases.
1661
Tim Petersecc6e6a2005-07-10 22:30:55 +00001662- SF bug #1185883: Python's small-object memory allocator took over
1663 a block managed by the platform C library whenever a realloc specified
1664 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001665 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001666 portable way to copy data from the C-managed block into Python's
1667 small-object space without risking a memory fault. Python's small-object
1668 realloc now leaves such blocks under the control of the platform C
1669 realloc.
1670
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001671- SF bug #1232517: An overflow error was not detected properly when
1672 attempting to convert a large float to an int in os.utime().
1673
Raymond Hettinger3296e692005-06-29 23:29:56 +00001674- SF bug #1224347: hex longs now print with lowercase letters just
1675 like their int counterparts.
1676
Michael W. Hudson188d4362005-06-20 16:52:57 +00001677- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1678 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1679 interpreter states; back out that fix and do a better job (see
1680 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1681 for a longer write-up of the problem).
1682
Michael W. Hudsondf888462005-06-03 14:41:55 +00001683- SF patch #1180995: marshal now uses a binary format by default when
1684 serializing floats.
1685
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001686- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1687 the routines that promise to produce IEEE 754 binary representations
1688 of floats now simply copy bytes around.
1689
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001690- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1691 278.
1692
Brett Cannonc3647ac2005-04-26 03:45:26 +00001693- patch #1109424: int, long, float, complex, and unicode now check for the
1694 proper magic slot for type conversions when subclassed. Previously the
1695 magic slot was ignored during conversion. Semantics now match the way
1696 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001697 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001698 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001699 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001700
Barry Warsawc8d907c2005-04-19 23:43:40 +00001701- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1702 NULL, now raise an AttributeError when attempting to set or delete the
1703 attribute. Previously a TypeError was raised, but this was inconsistent
1704 with the equivalent pure-Python implementation.
1705
Michael W. Hudson774479c2005-04-18 08:46:17 +00001706- It is now safe to call PyGILState_Release() before
1707 PyEval_InitThreads() (note that if there is reason to believe there
1708 are multiple threads around you still must call PyEval_InitThreads()
1709 before using the Python API; this fix is for extension modules that
1710 have no way of knowing if Python is multi-threaded yet).
1711
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001712- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1713 disabled caused a crash.
1714
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001715- Bug #1165306: instancemethod_new allowed the creation of a method
1716 with im_class == im_self == NULL, which caused a crash when called.
1717
Tim Petersecc6e6a2005-07-10 22:30:55 +00001718- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001719 fixes the crash seen in bug #1165761
1720
Raymond Hettinger96229b12005-03-11 06:49:40 +00001721- Added two new builtins, any() and all().
1722
Brett Cannon409d8f22005-03-05 06:47:57 +00001723- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001724 (e.g., ``class C(): pass`` is no longer a syntax error).
1725 Patch #1176012 added support to the 'parser' module and 'compiler' package
1726 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001727
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001728- Patch #1115086: Support PY_LONGLONG in structmember.
1729
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001730- Bug #1155938: new style classes did not check that __init__() was
1731 returning None.
1732
Tim Petersecc6e6a2005-07-10 22:30:55 +00001733- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001734 ('\') with a specific error message.
1735
Martin v. Löwisff232d72005-03-03 09:24:38 +00001736- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1737
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001738- Bug #1124295: the __name__ attribute of file objects was
1739 inadvertently made inaccessible in restricted mode.
1740
Tim Petersecc6e6a2005-07-10 22:30:55 +00001741- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001742 an ferror() call.
1743
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001744- min() and max() now support key= arguments with the same meaning as in
1745 list.sort().
1746
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001747- The peephole optimizer now performs simple constant folding in expressions:
1748 (2+3) --> (5).
1749
Raymond Hettingera422c342005-01-11 03:03:27 +00001750- set and frozenset objects can now be marshalled. SF #1098985.
1751
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001752- Bug #1077106: Poor argument checking could cause memory corruption
1753 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001754
Jeremy Hyltonab630502005-02-04 18:44:06 +00001755- The parser did not complain about future statements in illegal
1756 positions. It once again reports a syntax error if a future
1757 statement occurs after anything other than a doc string.
1758
Neil Schemenauercf52c072005-08-12 17:34:58 +00001759- Change the %s format specifier for str objects so that it returns a
1760 unicode instance if the argument is not an instance of basestring and
1761 calling __str__ on the argument returns a unicode instance.
1762
Tim Petersf4e69282006-02-27 17:15:31 +00001763- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1764 current thread state when the auto-GIL-state machinery knows about
1765 it (since the thread state is being deleted, continuing to remember it
1766 can't help, but can hurt if another thread happens to get created with
1767 the same thread id).

1770-----------------
1771
Georg Brandl43f08a82006-03-31 18:01:16 +00001772- Patch #1380952: fix SSL objects timing out on consecutive read()s
1773
Neal Norwitz05a45592006-03-20 06:30:08 +00001774- Patch #1309579: wait3 and wait4 were added to the posix module.
1775
Anthony Baxterfa869072006-03-20 05:21:58 +00001776- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1777 In addition, the existing ulaw code was updated.
1778
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001779- RFE #567972: Socket objects' family, type and proto properties are

Nick Coghlan43832302006-04-23 17:04:07 +00001963- PEP 338: new module runpy defines a run_module function to support
1964 executing modules which provide access to source code or a code object
1965 via the PEP 302 import mechanisms.

1975 in attribute values.
1976
Anthony Baxterc51ee692006-04-01 00:57:31 +00001977- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001978 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001979 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001980 module will not be built.
1981
Tim Petersc17976e2006-04-01 00:26:53 +00001982- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1983 aren't officially supported here, and trying to use them will probably
1984 raise an exception some day. But dicts have been allowed, and "mostly
1985 worked", so support for them won't go away without warning.
1986
Georg Brandl338ef7d2006-03-31 18:42:16 +00001987- Bug #1445068: getpass.getpass() can now be given an explicit stream

2005
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002006- email 4.0 package now integrated. This is largely the same as the email 3.0
2007 package that was included in Python 2.3, except that PEP 8 module names are
2008 now used (e.g. mail.message instead of email.Message). The MIME classes
2009 have been moved to a subpackage (e.g. email.mime.text instead of
2010 email.MIMEText). The old names are still supported for now. Several
2011 deprecated Message methods have been removed and lots of bugs have been
2012 fixed. More details can be found in the email package documentation.
2013
Walter Dörwald40108c92006-03-27 08:15:44 +00002014- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2015 (a subclass of tuple) that provides incremental decoders and encoders
2016 (a way to use stateful codecs without the stream API). Python functions
2017 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2018 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2019 have been added.

2022 a ValueError instead of a StopIteration now (like file and cString.String do).

2100 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2101 Ronald L. Rivest offered this advice for Python:
2102
2103 "The consensus of researchers in this area (at least as
2104 expressed at the NIST Hash Function Workshop 10/31/05),
2105 is that SHA-256 is a good choice for the time being, but
2106 that research should continue, and other alternatives may
2107 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002108

2289 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002290 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002291 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002292 + Dialect parameter parsing has been re-implemented to improve error

2294 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2295 dictates.
2296 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002297 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002298 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002299 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2300 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002301 + reader now allows \r characters to be quoted (previously it only allowed
2302 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002303 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002304 + Dialect classes passed to the module are no longer instantiated by
2305 the module before being parsed (the former validation scheme required
2306 this, but the mechanism was unreliable).
2307 + The dialect registry now contains instances of the internal
2308 C-coded dialect type, rather than references to python objects.
2309 + the internal c-coded dialect type is now immutable.
2310 + register_dialect now accepts the same keyword dialect specifications
2311 as the reader and writer, allowing the user to register dialects
2312 without first creating a dialect class.
2313 + a configurable limit to the size of parsed fields has been added -
2314 previously, an unmatched quote character could result in the entire
2315 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002316 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002317 the parser field size limit (returning the former limit). The initial
2318 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002319 + A line_num attribute has been added to the reader object, which tracks
2320 the number of lines read from the source iterator. This is not
2321 the same as the number of records returned, as records can span
2322 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002323 + reader and writer objects were not being registered with the cyclic-GC.
2324 This has been fixed.
2325
Brett Cannone6539c42005-01-08 02:43:53 +00002326- _DummyThread objects in the threading module now delete self.__block that is
2327 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2328 lock primitives tend to be limited in number and thus should not be wasted on
2329 a _DummyThread object. Fixes bug #1089632.
2330
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002331- The imghdr module now detects Exif files.
2332
Raymond Hettinger6065d322004-12-20 23:51:53 +00002333- StringIO.truncate() now correctly adjusts the size attribute.
2334 (Bug #951915).
2335
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002336- locale.py now uses an updated locale alias table (built using
2337 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2338 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002339 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002340
Raymond Hettinger3557f422004-12-07 12:02:02 +00002341- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2342
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002343- the pickle module no longer accepts the deprecated None option in the
2344 args tuple returned by __reduce__().
2345
Brett Cannon84667c02004-12-07 03:25:18 +00002346- optparse now optionally imports gettext. This allows its use in setup.py.
2347
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002348- the pickle module no longer uses the deprecated bin parameter.
2349
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002350- the shelve module no longer uses the deprecated binary parameter.
2351
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002352- the pstats module no longer uses the deprecated ignore() method.
2353
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002354- the filecmp module no longer uses the deprecated use_statcache argument.
2355
Raymond Hettinger664347b2004-12-04 21:21:53 +00002356- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2357 extended or overridden by subclasses. Formerly, the subclassed method would
2358 be ignored by the rest of the module. (Bug #1078905).
2359
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002360- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002361 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002362
Walter Dörwald36733692004-12-22 12:50:50 +00002363- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2364 once when a size argument is given. This prevents a buffer overflow in the
2365 tokenizer with very long source lines.
2366
Barry Warsaw538561e2006-01-01 21:48:54 +00002367- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2368 immediately after creating the object, without any intervening
2369 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002370
Skip Montanaro05885812005-01-16 20:48:27 +00002371- The reconvert.quote function can now emit triple-quoted strings. The
2372 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002373
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002374- ``UserString.MutableString`` now supports negative indices in
2375 ``__setitem__`` and ``__delitem__``
2376
Greg Ward40407942005-03-05 02:53:17 +00002377- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2378 correctly.
2379
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002380- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2381 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2382 character even if the user has passed a size parameter to get a proper
2383 line ending. Remove the special handling of a "\r\n" that has been split
2384 between two lines.
2385
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002386- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2387 about illegal code points. The codec now supports PEP 293 style error
2388 handlers.
2389
Walter Dörwald78a78b02005-09-01 12:04:29 +00002390- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002391 from the input stream, so that the output is a byte string in the correct
2392 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002393
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002394- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2395 considering it exactly like a '*'.
2396
Walter Dörwald007f8df2005-10-09 19:42:27 +00002397- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2398 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002399
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002400- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2401
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002402- Patch #1413711: Certain patterns of differences were making difflib
2403 touch the recursion limit.
2404
Walter Dörwald58917a62006-03-31 15:26:22 +00002405- Bug #947906: An object oriented interface has been added to the calendar
2406 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002407 called as a script (e.g. via ``python -mcalendar``). Localized month and
2408 weekday names can be ouput (even if an exotic encoding is used) using
2409 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002410

2412-----
2413
Neal Norwitz602d3392006-03-31 08:21:40 +00002414- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2415 by using -mieee gcc option.
2416
Martin v. Löwis86d66262006-02-17 08:40:11 +00002417- Patch #1432345: Make python compile on DragonFly.
2418
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002419- Build support for Win64-AMD64 was added.
2420
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002421- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2422
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002423- Patch #881820: look for openpty and forkpty also in libbsd.
2424
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002425- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2426 The zlib module is now builtin on Windows.
2427
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002428- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2429
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002430- Bug #1189330: configure did not correctly determine the necessary
2431 value of LINKCC if python was built with GCC 4.0.
2432
Trent Mick8321b422005-07-26 02:29:21 +00002433- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2434 vulnerability in zlib 1.2.1 and 1.2.2.
2435
Brett Cannon08cd5982005-04-24 22:26:38 +00002436- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2437 flags that change binary compatibility. Changes were also made to
2438 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002439 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002440
Bob Ippolitoed233462005-03-29 13:47:59 +00002441- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2442 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2443 no longer exists). This configure patch makes things right.
2444
Martin v. Löwise2713be2005-03-08 15:03:08 +00002445- Bug #1158607: Build with --disable-unicode again.
2446
Brett Cannon46d96232005-02-16 00:07:19 +00002447- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2448 defined. Discovered as a result of not being able to build on OS X.
2449
Brett Cannon516592f2004-12-07 00:42:59 +00002450- setup.py now uses the directories specified in LDFLAGS using the -L option
2451 and in CPPFLAGS using the -I option for adding library and include
2452 directories, respectively, for compiling extension modules against. This has
2453 led to the core being compiled using the values in CPPFLAGS. It also removes
2454 the need for the special-casing of both DarwinPorts and Fink for darwin since
2455 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2456 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2457 Fink, ``-I/opt/local/include`` for DarwinPorts).
2458
Brett Cannon43802422005-02-10 20:48:03 +00002459- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2460 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2461 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2462 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002464C API
2465-----
2466
Tim Petersc9d78aa2006-03-26 23:27:58 +00002467- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2468 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2469 is obtained via the ``PyObject_`` family, it must be released via the
2470 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2471 always been officially true, but when Python's small-object allocator was
2472 introduced, an attempt was made to cater to a few extension modules
2473 discovered at the time that obtained memory via ``PyObject_New`` but
2474 released it via ``PyMem_DEL``. It's years later, and if such code still
2475 exists it will fail now (probably with segfaults, but calling wrong
2476 low-level memory management functions can yield many symptoms).
2477
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002478- Added a C API for set and frozenset objects.
2479
Raymond Hettinger66517482004-12-03 11:45:13 +00002480- Removed PyRange_New().
2481
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002482- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2483 mapping argument now. This string is used as a mapping table. Byte values
2484 greater than the length of the string and 0xFFFE are treated as undefined
2485 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002492
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002493- Patch #1276356: New resource "urlfetch" is implemented. This enables
