Andrew M. Kuchling43889c02006-09-27 16:37:30 +0000310- Bug #1552726: in readline.c, avoid repeatedly polling in interactive
311 mode by only placing a timeout on the select() if an input hook has
312 been defined. This prevents an interactive Python from waking up 10
313 times per second. Patch by Richard Boulton.

318
Brett Cannon6d9520c2006-12-13 23:09:53 +0000319- Added guard_warnings_filter to test.test_support. It returns a context
320 manager that protects the 'warnings' module's filter from being mutated
321 once the context has been exited.
322
Thomas Heller112d1a62006-10-27 19:05:53 +0000323- Added some tests for modulefinder.

405Core and builtins
406-----------------
407
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000408- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000409 compared equal or unequal to a string and a UnicodeDecodeError
410 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000411
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000412 Instead, the equal (==) and unequal (!=) comparison operators will
413 now issue a UnicodeWarning and interpret the two objects as
414 unequal. The UnicodeWarning can be filtered as desired using
415 the warning framework, e.g. silenced completely, turned into an
416 exception, logged, etc.
417
418 Note that compare operators other than equal and unequal will still
419 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000420
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000421- Fix segfault when doing string formatting on subclasses of long.
422
423- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
424 with new-style classes.
425
426- Fix bug related to __len__ functions returning negative values with
427 classic classes.
428
429- Patch #1538606, Fix __index__() clipping. There were some problems
430 discovered with the API and how integers that didn't fit into Py_ssize_t
431 were handled. This patch attempts to provide enough alternatives
432 to effectively use __index__.
433
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000434- Bug #1536021: __hash__ may now return long int; the final hash
435 value is obtained by invoking hash on the long int.
436
Thomas Hellerab1049c2006-08-08 17:37:00 +0000437- Bug #1536786: buffer comparison could emit a RuntimeWarning.
438
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000439- Bug #1535165: fixed a segfault in input() and raw_input() when
440 sys.stdin is closed.
441
Thomas Heller74d36f02006-08-04 18:17:40 +0000442- On Windows, the PyErr_Warn function is now exported from
443 the Python dll again.
444
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000445- Bug #1191458: tracing over for loops now produces a line event
446 on each iteration. Fixing this problem required changing the .pyc
447 magic number. This means that .pyc files generated before 2.5c1
448 will be regenerated.
449
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000450- Bug #1333982: string/number constants were inappropriately stored
451 in the byte code and co_consts even if they were not used, ie
452 immediately popped off the stack.
453
Georg Brandle9462c72006-08-04 18:03:37 +0000454- Fixed a reference-counting problem in property().

457Library
458-------
459
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000460- Fix a bug in the ``compiler`` package that caused invalid code to be
461 generated for generator expressions.
462
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000463- The distutils version has been changed to 2.5.0. The change to
464 keep it programmatically in sync with the Python version running
465 the code (introduced in 2.5b3) has been reverted. It will continue
466 to be maintained manually as static string literal.
467
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000468- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000469 and this cannot be converted to the required C type, an exception is
470 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000471 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000472
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000473- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000474 an exception.
475
Tim Petersc10c9d02006-09-05 02:18:09 +0000476- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000477 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000478 workarounds for clocks with low resolution, to stop the code yielding
479 duplicate UUIDs.
480
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000481- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
482 before raising SystemExit, allowing IDLE to honor quit() and exit().
483
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000484- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
485
Georg Brandl7a1af772006-08-14 21:55:28 +0000486- Patch #1536071: trace.py should now find the full module name of a
487 file correctly even on Windows.
488
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000489- logging's atexit hook now runs even if the rest of the module has
490 already been cleaned up.
491
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000492- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000493
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000494- Bug #1531405, format_exception no longer raises an exception if
495 str(exception) raised an exception.
496
Neil Schemenauer06ded092006-08-04 16:20:30 +0000497- Fix a bug in the ``compiler`` package that caused invalid code to be
498 generated for nested functions.

507 raises the correct exceptions.
508
Thomas Heller1ce433e2006-08-14 16:20:04 +0000509- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
510 '-no-stack-protector' compiler flag for OpenBSD has been removed.
511
Thomas Heller86720042006-08-14 11:17:48 +0000512- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
513 uses the _as_parameter_ attribute when objects are passed to foreign
514 function calls. The ctypes version number was changed to 1.0.1.
515
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000516- Bug #1530559, struct.pack raises TypeError where it used to convert.
517 Passing float arguments to struct.pack when integers are expected
518 now triggers a DeprecationWarning.

568Core and builtins
569-----------------
570
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000571- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000572 returned a long (see PEP 353).
573
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000574- Bug #1515471: string.replace() accepts character buffers again.
575
Neal Norwitz07aadb12006-07-30 06:55:48 +0000576- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
577 This provides the proper warning for struct.pack().
578 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
579
Neal Norwitz0d62a062006-07-30 06:53:31 +0000580- Patch #1531113: Fix augmented assignment with yield expressions.
581 Also fix a SystemError when trying to assign to yield expressions.
582
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000583- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
584 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
585 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
586 excessive filesystem operations during imports.
587
Tim Petersbc24eee2006-07-27 01:14:53 +0000588- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
589 operations on signed longs that are formally undefined by C.
590 Unfortunately, at least one compiler now cares about that, so complicated
591 the code to make that compiler happy again.
592
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000593- Bug #1524310: Properly report errors from FindNextFile in os.listdir.

603 had more than 255 blank lines.
604
Georg Brandl9dceedb2006-07-12 15:31:17 +0000605- Patch #1521179: Python now accepts the standard options ``--help`` and

Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000608- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000609 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000610 This means that .pyc files generated before 2.5b3 will be regenerated.

Tim Peters112aad32006-07-19 00:03:19 +0000612- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000613 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000614 new ``sys._current_frames()`` returns a dictionary with one entry,
615 mapping the faux "thread id" 0 to the current frame.

621-------
622
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000623- Correction of patch #1455898: In the mbcs decoder, set final=False
624 for stream decoder, but final=True for the decode function.
625
Georg Brandl07fec3a2006-08-01 18:49:24 +0000626- os.urandom no longer masks unrelated exceptions like SystemExit or
627 KeyboardInterrupt.
628
Tim Peters4643c2f2006-08-10 22:45:34 +0000629- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000630 shutil.copytree on Windows
631
Georg Brandle34ac7c2006-07-30 11:07:23 +0000632- Bug #1002398: The documentation for os.path.sameopenfile now correctly
633 refers to file descriptors, not file objects.
634
Tim Petersc10c9d02006-09-05 02:18:09 +0000635- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000636 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000637 #1513611, and probably others.
638
Georg Brandledd9b0d2006-07-29 09:33:26 +0000639- Bug #1441397: The compiler module now recognizes module and function
640 docstrings correctly as it did in Python 2.4.
641
Tim Peters6f681472006-07-27 23:44:37 +0000642- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
643 lost that tests are sorted by name before being run. This rarely
644 matters for well-written tests, but can create baffling symptoms if
645 side effects from one test to the next affect outcomes. ``DocTestFinder``
646 has been changed to sort the list of tests it returns.
647
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000648- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000649 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000650
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000651- Bug #978833: Really close underlying socket in _socketobject.close.
652
Georg Brandl8c036cc2006-08-20 13:15:39 +0000653- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
654 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000655
Georg Brandlcf0c1722006-07-26 07:23:32 +0000656- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
657 to recursive calls and call it with the failing package name.
658
Martin v. Löwis0b483032006-07-25 09:53:12 +0000659- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
660
Georg Brandlc13c34c2006-07-24 14:09:56 +0000661- Patch #1515343: Fix printing of deprecated string exceptions with a
662 value in the traceback module.
663
Greg Ward48fae7a2006-07-23 16:05:51 +0000664- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
665
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000666- Patch #1524429: Use repr() instead of backticks in Tkinter again.
667
Brett Cannoncaebe222006-07-18 04:41:36 +0000668- Bug #1520914: Change time.strftime() to accept a zero for any position in its
669 argument tuple. For arguments where zero is illegal, the value is forced to
670 the minimum value that is correct. This is to support an undocumented but
671 common way people used to fill in inconsequential information in the time
672 tuple pre-2.4.
673
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000674- Patch #1220874: Update the binhex module for Mach-O.
675
Barry Warsawb110bad2006-07-21 14:51:07 +0000676- The email package has improved RFC 2231 support, specifically for
677 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
678 (name*0=<blah>) parameter continuations. This may change the types of
679 values returned from email.message.Message.get_param() and friends.
680 Specifically in some cases where non-encoded continuations were used,
681 get_param() used to return a 3-tuple of (None, None, string) whereas now it
682 will just return the string (since non-encoded continuations don't have
683 charset and language parts).
684
685 Also, whereas % values were decoded in all parameter continuations, they are
686 now only decoded in encoded parameter parts.
687
Ronald Oussoren3075e162006-07-25 20:28:55 +0000688- Bug #1517990: IDLE keybindings on MacOS X now work correctly
689
690- Bug #1517996: IDLE now longer shows the default Tk menu when a
691 path browser, class browser or debugger is the frontmost window on MacOS X
692
Barry Warsaw00decd72006-07-27 23:43:15 +0000693- Patch #1520294: Support for getset and member descriptors in types.py,
694 inspect.py, and pydoc.py. Specifically, this allows for querying the type
695 of an object against these built-in types and more importantly, for getting
696 their docstrings printed in the interactive interpreter's help() function.

701
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000702- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
703 a socket operation on a socket with a timeout, the exception will be
704 caught correctly. Previously, the exception was not caught.
705
Thomas Heller1393d6a2006-07-28 21:43:20 +0000706- Patch #1529514: The _ctypes extension is now compiled on more
707 openbsd target platforms.
708
Tim Peters9cab5932006-07-28 00:30:00 +0000709- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
710 a memory leak, affecting pickles and deep copies.
711
Tim Petersbc24eee2006-07-27 01:14:53 +0000712- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

714
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000715- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
716
Thomas Hellerce049a02006-07-14 17:51:14 +0000717- Patch #1521817: Index range checking on ctypes arrays containing
718 exactly one element enabled again. This allows iterating over these
719 arrays, without the need to check the array size before.
720
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000721- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000722 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000723 /dev/null in certain cases; this is now fixed.
724
Thomas Heller47d7a062006-07-12 08:43:47 +0000725- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
726 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000727
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000728- Because of a misspelled preprocessor symbol, ctypes was always
729 compiled without thread support; this is now fixed.
730
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000731- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
732 methods now allow their database parameter to be None as the
733 sleepycat API allows.
734
Matt Flemingec926502006-07-28 11:27:27 +0000735- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
736 bluetooth API compared with Linux and FreeBSD.
737
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000738Tests
739-----
740
741- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
742 how long the test file should take to play. Now accepts taking 2.93 secs
743 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
744
Georg Brandl4793aa32006-07-28 18:31:39 +0000745- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
746 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
747 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +0000754Mac
755---
756
757- PythonLauncher now works correctly when the path to the script contains
758 characters that are treated specially by the shell (such as quotes).
759
760- Bug #1527397: PythonLauncher now launches scripts with the working directory
761 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000762 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000763 expect.

772-----------------
773
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000774- Bug #1441486: The literal representation of -(sys.maxint - 1)
775 again evaluates to a int object, not a long.
776
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000777- Bug #1501934: The scope of global variables that are locally assigned
778 using augmented assignment is now correctly determined.
779
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000780- Bug #927248: Recursive method-wrapper objects can now safely
781 be released.
782
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000783- Bug #1417699: Reject locale-specific decimal point in float()
784 and atof().
785
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000786- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
787 omit a default "error" argument for NULL pointer. This allows
788 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000789
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000790- Bug #1519018: 'as' is now validated properly in import statements.
791
Neal Norwitz28746ab2006-07-09 22:14:42 +0000792- On 64 bit systems, int literals that use less than 64 bits are
793 now ints rather than longs.
794
Neal Norwitzed657552006-07-10 00:04:44 +0000795- Bug #1512814, Fix incorrect lineno's when code at module scope
796 started after line 256.
797
Tim Peters32a83612006-07-10 21:08:24 +0000798- New function ``sys._current_frames()`` returns a dict mapping thread
799 id to topmost thread stack frame. This is for expert use, and is
800 especially useful for debugging application deadlocks. The functionality
801 was previously available in Fazal Majid's ``threadframe`` extension
802 module, but it wasn't possible to do this in a wholly threadsafe way from
803 an extension.

Martin v. Löwis2b88f632006-07-03 10:19:49 +0000835 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000836
Martin v. Löwisbd39c032006-07-03 09:44:00 +0000837- Bug #1514703: Only setup canvas window in turtle when the canvas
838 is created.
839
Martin v. Löwis7596e832006-07-01 15:33:37 +0000840- Bug #1513223: .close() of a _socketobj now releases the underlying
841 socket again, which then gets closed as it becomes unreferenced.

844 attribute values.
845
846- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
847 sgmllib ('[' and ']' were not accepted).
848
Georg Brandl1be63af2006-06-28 20:23:25 +0000849- Fix a bug in the turtle module's end_fill function.
850
Brett Cannon53ab5b72006-06-22 16:49:14 +0000851- Bug #1510580: The 'warnings' module improperly required that a Warning
852 category be either a types.ClassType and a subclass of Warning. The proper
853 check is just that it is a subclass with Warning as the documentation states.
854
Georg Brandlad29e632006-06-21 17:45:17 +0000855- The compiler module now correctly compiles the new try-except-finally
856 statement (bug #1509132).
857
Neal Norwitz60373cd2006-06-22 06:30:50 +0000858- The wsgiref package is now installed properly on Unix.
859
Vinay Sajip28e57612006-07-01 10:45:20 +0000860- A bug was fixed in logging.config.fileConfig() which caused a crash on
861 shutdown when fileConfig() was called multiple times.
862
Gerhard Häring762fbd32006-07-02 17:48:30 +0000863- The sqlite3 module did cut off data from the SQLite database at the first
864 null character before sending it to a custom converter. This has been fixed
865 now.

Tim Peters112aad32006-07-19 00:03:19 +0000870- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
871 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
872 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000873
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000874- Assigning None to pointer type fields in ctypes structures possible
875 overwrote the wrong fields, this is fixed now.
876
877- Fixed a segfault in _ctypes when ctypes.wintypes were imported
878 on non-Windows platforms.
879
880- Bug #1518190: The ctypes.c_void_p constructor now accepts any
881 integer or long, without range checking.
882
883- Patch #1517790: It is now possible to use custom objects in the ctypes
884 foreign function argtypes sequence as long as they provide a from_param
885 method, no longer is it required that the object is a ctypes type.
886
887- The '_ctypes' extension module now works when Python is configured
888 with the --without-threads option.
889
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000890- Bug #1513646: os.access on Windows now correctly determines write

Tim Peters32a83612006-07-10 21:08:24 +0000906- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000907 Previously, the slight difference could cause compilation errors of the
908 'zlib' module on systems with more than one version of zlib.
909
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000910- The MSI compileall step was fixed to also support a TARGETDIR
911 with spaces in it.
912
Martin v. Löwis88ef6372006-07-06 06:55:58 +0000913- Bug #1517388: sqlite3.dll is now installed on Windows independent
914 of Tcl/Tk.
915
Neal Norwitzc315a0f2006-06-27 04:28:56 +0000916- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +0000917 trying to be installed even though it's empty.

929 documentation for the warnings module.
930
Martin v. Löwis1bf59592006-06-29 18:58:44 +0000931- Patch #1509163: MS Toolkit Compiler no longer available.

Anthony Baxterd1136802006-06-19 12:04:15 +0000939*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +0000940
941Core and builtins
942-----------------
943
Georg Brandla56b9152006-06-19 06:35:54 +0000944- Patch #1507676: Error messages returned by invalid abstract object operations
945 (such as iterating over an integer) have been improved and now include the
946 type of the offending object to help with debugging.
947
Brett Cannonea3912b2006-06-13 21:46:41 +0000948- Bug #992017: A classic class that defined a __coerce__() method that returned
949 its arguments swapped would infinitely recurse and segfault the interpreter.
950
Neal Norwitz909eb122006-06-12 02:13:21 +0000951- Fix the socket tests so they can be run concurrently.
952
Neal Norwitzb9845e72006-06-12 02:11:18 +0000953- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000954 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000955
Brett Cannon22565aa2006-06-09 22:31:23 +0000956- Bug #532646: object.__call__() will continue looking for the __call__
957 attribute on objects until one without one is found. This leads to recursion
958 when you take a class and set its __call__ attribute to an instance of the
959 class. Originally fixed for classic classes, but this fix is for new-style.
960 Removes the infinite_rec_3 crasher.
961
Georg Brandl24250812006-06-09 18:45:48 +0000962- The string and unicode methods startswith() and endswith() now accept
963 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
964
Brett Cannonde3b0522006-06-08 17:00:45 +0000965- Buffer objects, at the C level, never used the char buffer
966 implementation even when the char buffer for the wrapped object was
967 explicitly requested (originally returned the read or write buffer).
968 Now a TypeError is raised if the char buffer is not present but is
969 requested.
970
Georg Brandlddbaa662006-06-04 21:56:52 +0000971- Patch #1346214: Statements like "if 0: suite" are now again optimized
972 away like they were in Python 2.4.
973
Georg Brandlb7c8f542006-05-27 12:30:25 +0000974- Builtin exceptions are now full-blown new-style classes instead of
975 instances pretending to be classes, which speeds up exception handling
976 by about 80% in comparison to 2.5a2.
977
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000978- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
979 Unicode 4.1.
980
Georg Brandlf4ef1162006-05-26 18:03:31 +0000981- Patch #921466: sys.path_importer_cache is now used to cache valid and
982 invalid file paths for the built-in import machinery which leads to
983 fewer open calls on startup.
984
Tim Peters696cf432006-05-24 21:10:40 +0000985- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
986 of-2 bases. The largest speedup is for inputs with about 1000 decimal
987 digits. Conversion from non-power-of-2 bases remains quadratic-time in
988 the number of input digits (it was and remains linear-time for bases
989 2, 4, 8, 16 and 32).
990
Tim Petersb713ec22006-05-23 18:45:30 +0000991- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
992 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
993 an integer close to ``sys.maxint``. This was repaired by patch
994 #1335972, which also gives a nice speedup.
995
Richard Jonescebbefc2006-05-23 18:28:17 +0000996- Patch #1337051: reduced size of frame objects.
997
998- PyErr_NewException now accepts a tuple of base classes as its
999 "base" parameter.
1000
Richard Jones7c88dcc2006-05-23 10:37:38 +00001001- Patch #876206: function call speedup by retaining allocated frame
1002 objects.
1003
Georg Brandl7b90e162006-05-18 07:01:27 +00001004- Bug #1462152: file() now checks more thoroughly for invalid mode
1005 strings and removes a possible "U" before passing the mode to the
1006 C library function.
1007
Neal Norwitz1004a532006-05-15 07:17:23 +00001008- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1009
Neal Norwitz373f0a72006-05-15 07:04:36 +00001010- Bug #1487966: Fix SystemError with conditional expression in assignment
1011
Martin v. Löwis879768d2006-05-11 13:28:43 +00001012- WindowsError now has two error code attributes: errno, which carries
1013 the error values from errno.h, and winerror, which carries the error
1014 values from winerror.h. Previous versions put the winerror.h values
1015 (from GetLastError()) into the errno attribute.
1016
Martin v. Löwis77736712006-05-04 05:51:03 +00001017- Patch #1475845: Raise IndentationError for unexpected indent.
1018
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001019- Patch #1479181: split open() and file() from being aliases for each other.
1020
Tim Peters44bd9862006-06-01 13:49:23 +00001021- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1022 methods were always silently ignored by dictionaries when comparing keys.
1023 They are now passed through (except when using the C API function
1024 ``PyDict_GetItem()``, whose semantics did not change).
1025
1026- Bug #1456209: In some obscure cases it was possible for a class with a
1027 custom ``__eq__()`` method to confuse dict internals when class instances
1028 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1029 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001031Extension Modules
1032-----------------
1033
Trent Mick960a3f82006-06-28 20:30:41 +00001034- Bug #1295808: expat symbols should be namespaced in pyexpat
1035
1036- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1037
Brett Cannon6ee7d012006-06-08 16:23:04 +00001038- Change binascii.hexlify to accept a read-only buffer instead of only a char
1039 buffer and actually follow its documentation.
1040
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001041- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1042
Nick Coghlanc649ec52006-05-29 12:43:05 +00001043- Patch #1478788 (modified version): The functional extension module has
1044 been renamed to _functools and a functools Python wrapper module added.
1045 This provides a home for additional function related utilities that are
1046 not specifically about functional programming. See PEP 309.
1047
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001048- Patch #1493701: performance enhancements for struct module.
1049
Georg Brandl378d5922006-05-17 14:26:50 +00001050- Patch #1490224: time.altzone is now set correctly on Cygwin.
1051
Georg Brandl8d3342b2006-05-16 07:38:27 +00001052- Patch #1435422: zlib's compress and decompress objects now have a
1053 copy() method.
1054
Andrew MacIntyre92913322006-06-13 15:04:24 +00001055- Patch #1454481: thread stack size is now tunable at runtime for thread
1056 enabled builds on Windows and systems with Posix threads support.
1057
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001058- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1059 (up to the system limit of 32K characters).
1060
1061- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1062 As a result, these functions now raise WindowsError instead of OSError.
1063
Tim Peters7a822da2006-05-25 21:50:17 +00001064- ``time.clock()`` on Win64 should use the high-performance Windows
1065 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1066 Windows platforms).
1067
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001068- Calling Tk_Init twice is refused if the first call failed as that
1069 may deadlock.
1070
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001071- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1072 accept it without potentially using an uninitialized pointer.
1073
1074- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1075 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1076 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001077
Gregory P. Smith372b5832006-06-05 18:48:21 +00001078- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001079 [pybsddb project SF patch number 1466734]
1080
Gregory P. Smith372b5832006-06-05 18:48:21 +00001081- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1082 parameter is supplied. [SF pybsddb bug #1477863]
1083
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001084- bsddb: the __len__ method of a DB object has been fixed to return correct
1085 results. It could previously incorrectly return 0 in some cases.
1086 Fixes SF bug 1493322 (pybsddb bug 1184012).
1087
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001088- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1089 aborts the db transaction safely when a modifier callback fails.
1090 Fixes SF python patch/bug #1408584.
1091
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001092- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001093 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001094 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1095 database calls that would previously deadlock. [SF python bug #775414]
1096
Vinay Sajip28e57612006-07-01 10:45:20 +00001097- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001098
Walter Dörwald4994d952006-06-19 08:07:50 +00001099- Patch #1506645: add Python wrappers for the curses functions
1100 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001101

1103-------
1104
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001105- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1106 functions.
1107
Martin v. Löwis3798da02006-06-17 18:44:27 +00001108- Patch #812986: Update turtle output even if not tracing.
1109
Vinay Sajip28e57612006-07-01 10:45:20 +00001110- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001111 Tkinter.BaseWidget.
1112
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001113- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1114
Martin v. Löwis337487e2006-06-17 09:15:14 +00001115- Patch #763580: Add name and value arguments to Tkinter variable
1116 classes.
1117
Georg Brandl83cc0d02006-06-14 08:50:03 +00001118- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1119 mime.types file for determining MIME types.
1120
Georg Brandl2605ca82006-06-14 06:08:31 +00001121- Bug #1339007: Shelf objects now don't raise an exception in their
1122 __del__ method when initialization failed.
1123
Martin v. Löwisd8251432006-06-14 05:21:04 +00001124- Patch #1455898: The MBCS codec now supports the incremental mode for
1125 double-byte encodings.
1126
Tim Peters43898b42006-06-14 04:09:25 +00001127- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1128 guarantee that adjacent triples in the return list always describe
1129 non-adjacent blocks. Previously, a pair of matching blocks could end
1130 up being described by multiple adjacent triples that formed a partition
1131 of the matching pair.
1132
Greg Ward0e0c9f42006-06-11 16:24:11 +00001133- Bug #1498146: fix optparse to handle Unicode strings in option help,
1134 description, and epilog.
1135
Greg Wardd1c797e2006-06-11 14:42:41 +00001136- Bug #1366250: minor optparse documentation error.
1137
Greg Ward7f547402006-06-11 00:40:49 +00001138- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1139 clarify docs.
1140
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001141- The wsgiref package has been added to the standard library.
1142
Nick Coghlan676725d2006-06-08 13:54:49 +00001143- The functions update_wrapper() and wraps() have been added to the functools
1144 module. These make it easier to copy relevant metadata from the original
1145 function when writing wrapper functions.
1146
Tim Petersd6a9eef2006-06-05 01:48:21 +00001147- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1148 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001149
Martin v. Löwis3f767792006-06-04 19:36:28 +00001150- Patch #1359618: Speed up charmap encoder by using a trie structure
1151 for lookup.
1152
Tim Petersd609b1a2006-06-02 23:22:51 +00001153- The functions in the ``pprint`` module now sort dictionaries by key
1154 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1155 if and only if its display required more than one line, although that
1156 wasn't documented. The new behavior increases predictability; e.g.,
1157 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1158
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001159- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1160 (thanks for J. J. Lee).
1161
Georg Brandl2b330372006-05-28 20:23:12 +00001162- Patch #1496206: improve urllib2 handling of passwords with respect to
1163 default HTTP and HTTPS ports.
1164
George Yoshidaf3c65de2006-05-28 16:39:09 +00001165- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1166
Bob Ippolito7298f272006-05-23 18:43:47 +00001167- Patch #1281707: speed up gzip.readline.
1168
Georg Brandlb89316f2006-05-17 15:51:16 +00001169- Patch #1180296: Two new functions were added to the locale module:
1170 format_string() to get the effect of "format % items" but locale-aware,
1171 and currency() to format a monetary number with currency sign.
1172
Georg Brandle3a25832006-05-17 14:56:04 +00001173- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1174 and several features added, such as speed and geometry control.
1175
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001176- Patch #1488881: add support for external file objects in bz2 compressed
1177 tarfiles.
1178
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001179- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1180 stdout arguments, making it possible to redirect input and output
1181 for remote debugging.
1182
1183- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1184 a couple of issues, notably handling of long file names using the
1185 GNU LONGNAME extension.
1186
1187- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1188 new flag when ``name`` is already the name of an option flag.
1189
1190- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1191 package.
1192
1193- Patch #1472854: make the rlcompleter.Completer class usable on non-
1194 UNIX platforms.
1195

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001229What's New in Python 2.5 alpha 2?
1230=================================
1231
1232*Release date: 27-APR-2006*
1233
1234Core and builtins
1235-----------------
1236
Thomas Heller1b046642006-04-18 18:51:06 +00001237- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1238 by converting these apis from macros into exported functions again:
1239
1240 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1241 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1242 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1243 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1244 PyRun_String Py_CompileString
1245
Martin v. Löwis45294a92006-04-18 06:24:08 +00001246- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1247
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001248- All uses of PyStructSequence_InitType have been changed to initialize
1249 the type objects only once, even if the interpreter is initialized
1250 multiple times.
1251
Neal Norwitz61546162006-04-14 05:20:28 +00001252- Bug #1454485, array.array('u') could crash the interpreter. This was
1253 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1254 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1255
1256- Py_UNICODE is unsigned. It was always documented as unsigned, but
1257 due to a bug had a signed value in previous versions.
1258
Tim Peters3a5e8b12006-04-11 01:44:07 +00001259- Patch #837242: ``id()`` of any Python object always gives a positive
1260 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1261 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001262 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001263 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001264
Tim Peters3a5e8b12006-04-11 01:44:07 +00001265 def __hash__(self):
1266 return id(self) # WRONG
1267
1268 because a hash result must be a (short) Python int but it was always
1269 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001270 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001271 was always usable as a hash value before this patch. That's no longer
1272 necessarily so.
1273
1274- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001275 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001276 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001277 #1454844)
1278
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001279- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1280 involving generators that have paused outside of any ``try`` or ``with``
1281 blocks. (In 2.5a1, a paused generator that was part of a reference
1282 cycle could not be garbage collected, regardless of whether it was
1283 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001284
Anthony Baxter51bcb682006-04-05 14:51:42 +00001285Extension Modules

1287
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001288- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1289 is a macro.
1290
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001291- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1292 fails with an error condition.
1293
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001294- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1295
1296- Bug #1117761: bsddb.*open() no longer raises an exception when using
1297 the cachesize parameter.
1298
1299- Bug #1149413: bsddb.*open() no longer raises an exception when using
1300 a temporary db (file=None) with the 'n' flag to truncate on open.
1301
1302- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1303 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001304
Armin Rigoa9017c32006-04-19 11:50:27 +00001305- Patch #1062014: AF_UNIX sockets under Linux have a special
1306 abstract namespace that is now fully supported.
1307
Anthony Baxter51bcb682006-04-05 14:51:42 +00001308Library
1309-------
1310
Peter Astrand7d1d4362006-07-14 14:04:45 +00001311- Bug #1223937: subprocess.CalledProcessError reports the exit status
1312 of the process using the returncode attribute, instead of
1313 abusing errno.
1314
Tim Peters711bf302006-04-25 03:31:36 +00001315- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1316 a doctest to be skipped (the code is not run, and the expected output
1317 or exception is ignored).
1318
Nick Coghlanda2268f2006-04-24 04:37:15 +00001319- Fixed contextlib.nested to cope with exceptions being raised and
1320 caught inside exit handlers.
1321
Greg Wardab05edc2006-04-23 03:47:58 +00001322- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1323 hex, octal, or binary; add ``append_const`` action; keep going if
1324 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1325 added ``epilog`` for better help generation).
1326
Tim Peters21fbd572006-04-21 21:18:10 +00001327- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1328 called from a thread spawned as a side effect of importing a module.
1329
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001330- The pydoc module now supports documenting packages contained in
1331 .zip or .egg files.
1332
1333- The pkgutil module now has several new utility functions, such
1334 as ``walk_packages()`` to support working with packages that are either
1335 in the filesystem or zip files.
1336
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001337- The mailbox module can now modify and delete messages from
1338 mailboxes, in addition to simply reading them. Thanks to Gregory
1339 K. Johnson for writing the code, and to the 2005 Google Summer of
1340 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001341
Tim Petersc7605f22006-04-17 21:12:33 +00001342- The ``__del__`` method of class ``local`` in module ``_threading_local``
1343 returned before accomplishing any of its intended cleanup.
1344
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001345- Patch #790710: Add breakpoint command lists in pdb.
1346
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001347- Patch #1063914: Add Tkinter.Misc.clipboard_get().
1348
Martin v. Löwis4b501e62006-04-15 08:41:11 +00001349- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1350
Anthony Baxtere29002c2006-04-12 12:07:31 +00001351- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1352 Windows. Bug #1469163.
1353
Phillip J. Eby47032112006-04-11 01:07:43 +00001354- The warnings, linecache, inspect, traceback, site, and doctest modules
1355 were updated to work correctly with modules imported from zipfiles or
1356 via other PEP 302 __loader__ objects.
1357
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001358- Patch #1467770: Reduce usage of subprocess._active to processes which
1359 the application hasn't waited on.
1360
Martin v. Löwisb04dee92006-04-10 08:34:21 +00001361- Patch #1462222: Fix Tix.Grid.
1362
Neal Norwitza31bf182006-04-09 03:35:43 +00001363- Fix exception when doing glob.glob('anything*/')
1364
Skip Montanaro262fb922006-04-21 02:31:07 +00001365- The pstats.Stats class accepts an optional stream keyword argument to
1366 direct output to an alternate file-like object.
1367
Anthony Baxter51bcb682006-04-05 14:51:42 +00001368Build
1369-----
1370
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001371- The Makefile now has a reindent target, which runs reindent.py on
1372 the library.
1373
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001374- Patch #1470875: Building Python with MS Free Compiler
1375
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001376- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001377
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001378- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1379 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001380 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001381 CXX from --with-cxx-main, see description in README.
1382
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001383- Patch #1429775: Link extension modules with the shared libpython.
1384
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001385- Fixed a libffi build problem on MIPS systems.
1386
Tim Peters8931ff12006-05-13 23:28:20 +00001387- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1388 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1389 and "%zu" for unsigned integers of type ``size_t``.
1390
Anthony Baxter51bcb682006-04-05 14:51:42 +00001391Tests
1392-----
1393
Nick Coghlanda2268f2006-04-24 04:37:15 +00001394- test_contextlib now checks contextlib.nested can cope with exceptions
1395 being raised and caught inside exit handlers.
1396
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001397- test_cmd_line now checks operation of the -m and -c command switches
1398
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001399- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1400 it separately and by hand. It also wasn't cleaning up its changes to
1401 the current Decimal context.
1402
Thomas Woutersabd08882006-04-26 15:53:30 +00001403- regrtest.py now has a -M option to run tests that test the new limits of
1404 containers, on 64-bit architectures. Running these tests is only sensible
1405 on 64-bit machines with more than two gigabytes of memory. The argument
1406 passed is the maximum amount of memory for the tests to use.
1407
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001408Tools

1411- Added the Python benchmark suite pybench to the Tools/ directory;
1412 contributed by Marc-Andre Lemburg.
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001413
Anthony Baxter51bcb682006-04-05 14:51:42 +00001414Documentation
1415-------------
1416
Tim Petersb06d28c2006-05-12 01:57:59 +00001417- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1418
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001419- PEP 343: Added Context Types section to the library reference
1420 and attempted to bring other PEP 343 related documentation into
1421 line with the implementation and/or python-dev discussions.
1422
Tim Peters8dc73d22006-04-24 02:03:16 +00001423- Bug #1337990: clarified that ``doctest`` does not support examples
1424 requiring both expected output and an exception.
Anthony Baxter51bcb682006-04-05 14:51:42 +00001425

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001427What's New in Python 2.5 alpha 1?
1428=================================
1429
Anthony Baxterebed3f62006-04-03 15:03:44 +00001430*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001431
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001432Core and builtins
1433-----------------
1434
Nick Coghlan43832302006-04-23 17:04:07 +00001435- PEP 338: -m command line switch now delegates to runpy.run_module
1436 allowing it to support modules in packages and zipfiles
1437
Martin v. Löwisc661b882006-04-20 04:54:23 +00001438- On Windows, .DLL is not an accepted file name extension for
1439 extension modules anymore; extensions are only found if they
1440 end in .PYD.
1441
Martin v. Löwisea62d252006-04-03 10:56:49 +00001442- Bug #1421664: sys.stderr.encoding is now set to the same value as
1443 sys.stdout.encoding.
1444
Neal Norwitz92e212f2006-04-03 04:48:37 +00001445- __import__ accepts keyword arguments.
1446
Georg Brandlccadf842006-03-31 18:54:53 +00001447- Patch #1460496: round() now accepts keyword arguments.
1448
Anthony Baxter262c00a2006-03-30 10:53:17 +00001449- Fixed bug #1459029 - unicode reprs were double-escaped.
1450
Hye-Shik Changd478f342006-03-23 12:32:36 +00001451- Patch #1396919: The system scope threads are reenabled on FreeBSD
1452 5.4 and later versions.
1453
Neal Norwitze98ccf62006-03-23 05:39:47 +00001454- Bug #1115379: Compiling a Unicode string with an encoding declaration
1455 now gives a SyntaxError.
1456
Georg Brandlabd1ff82006-03-18 07:59:59 +00001457- Previously, Python code had no easy way to access the contents of a
1458 cell object. Now, a ``cell_contents`` attribute has been added
1459 (closes patch #1170323).
1460
Tim Peterscf79aac2006-03-16 01:14:46 +00001461- Patch #1123430: Python's small-object allocator now returns an arena to
1462 the system ``free()`` when all memory within an arena becomes unused
1463 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1464 freed. Some applications will see a drop in virtual memory size now,
1465 especially long-running applications that, from time to time, temporarily
1466 use a large number of small objects. Note that when Python returns an
1467 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001468 platform C library will in turn return that memory to the operating system.
1469 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001470 appears to be effective at least on Microsoft C and gcc-based systems.
1471 Thanks to Evan Jones for hard work and patience.
1472
Georg Brandl533ff6f2006-03-08 18:09:27 +00001473- Patch #1434038: property() now uses the getter's docstring if there is
1474 no "doc" argument given. This makes it possible to legitimately use
1475 property() as a decorator to produce a read-only property.
1476
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001477- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1478 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1479 of requiring an int or long in slicing and a few other contexts, enabling
1480 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1481
Neal Norwitz995acdf2006-03-07 05:01:00 +00001482- Fixed various bugs reported by Coverity's Prevent tool.
1483
Brett Cannonbf364092006-03-01 04:25:17 +00001484- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1485 new exception base class, BaseException, which has a new message attribute.
1486 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1487 Raising a string exception now raises a DeprecationWarning.
1488
Thomas Woutersfb609f42006-02-28 16:37:25 +00001489- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1490 explicitly relative, using 'from .module import name' to mean 'from the same
1491 package as this module is in. Imports without dots still default to the
1492 old relative-then-absolute, unless 'from __future__ import
1493 absolute_import' is used.
1494
Brett Cannona7446e32006-02-27 23:39:10 +00001495- Properly check if 'warnings' raises an exception (usually when a filter set
1496 to "error" is triggered) when raising a warning for raising string
1497 exceptions.
1498
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001499- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001500 The name was removed from Include/code.h.
1501
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001502- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001503
Guido van Rossum1968ad32006-02-25 22:38:04 +00001504- Patch 1433928:
1505 - The copy module now "copies" function objects (as atomic objects).
1506 - dict.__getitem__ now looks for a __missing__ hook before raising
1507 KeyError.
1508
Tim Peters84ef21c2006-02-28 20:39:06 +00001509- PEP 343: with statement implemented. Needs ``from __future__ import
1510 with_statement``. Use of 'with' as a variable will generate a warning.
1511 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001512 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001513 The following objects have __context__ methods:
1514 - The built-in file type.
1515 - The thread.LockType type.
1516 - The following types defined by the threading module:
1517 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1518 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001519
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001520- Fix the encodings package codec search function to only search
1521 inside its own package. Fixes problem reported in patch #1433198.
1522
1523 Note: Codec packages should implement and register their own
1524 codec search function. PEP 100 has the details.
1525
Tim Peters9ea89d22006-06-04 03:26:02 +00001526- PEP 353: Using ``Py_ssize_t`` as the index type.
1527
1528- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1529 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1530 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1531 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1532 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001533
Neal Norwitzfc76d632006-01-10 06:03:13 +00001534- Patch #1400181, fix unicode string formatting to not use the locale.
1535 This is how string objects work. u'%f' could use , instead of .
1536 for the decimal point. Now both strings and unicode always use periods.
1537
Neal Norwitz671b9e32006-01-09 07:07:12 +00001538- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1539 configure would break checking curses.h.
1540
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001541- Bug #959576: The pwd module is now builtin. This allows Python to be
1542 built on UNIX platforms without $HOME set.
1543
Neal Norwitzc10978f2005-12-19 06:07:16 +00001544- Bug #1072182, fix some potential problems if characters are signed.
1545
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001546- Bug #889500, fix line number on SyntaxWarning for global declarations.
1547
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001548- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1549
Neal Norwitze7214a12005-12-18 05:03:17 +00001550- Support for converting hex strings to floats no longer works.
1551 This was not portable. float('0x3') now raises a ValueError.
1552
Barry Warsaw2a38a862005-12-18 01:27:35 +00001553- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001554 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001555 is now displayed in interactive prompt banner.
1556
Georg Brandlfa166682005-12-17 21:45:17 +00001557- Implementation of PEP 341 - Unification of try/except and try/finally.
1558 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001559 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001560
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001561- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1562 now encodes backslash correctly.
1563
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001564- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1565
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001566- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001567 and long longs.
1568
Neal Norwitz67715f02005-11-09 06:59:35 +00001569- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001570 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001571 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001572
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001573- Replaced most Unicode charmap codecs with new ones using the
1574 new Unicode translate string feature in the builtin charmap
1575 codec; the codecs were created from the mapping tables available
1576 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1577 encodings now include a mapping for the Apple logo)
1578
Tim Peterse3547fd2005-12-16 23:13:57 +00001579- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001580
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001581- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001582
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001583- A new AST parser implementation was completed. The abstract
1584 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001585 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001586
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001587- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001588 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1589
Neal Norwitz708e51a2005-10-03 04:48:15 +00001590- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1591
Neal Norwitz11bd1192005-10-03 00:54:56 +00001592- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1593 Provide a warning when a directory is passed on the command line.
1594
Neal Norwitz40d37812005-10-02 01:48:49 +00001595- Fix segfault with invalid coding.
1596
1597- SF bug #772896: unknown encoding results in MemoryError.
1598
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001599- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001600 supported a __len__() method which evaluated to False when the iterator
1601 was empty.
1602
Guido van Rossum630db602005-09-20 18:49:54 +00001603- On 64-bit platforms, when __len__() returns a value that cannot be
1604 represented as a C int, raise OverflowError.
1605
Skip Montanarof8948ca2005-09-19 03:54:46 +00001606- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001607 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001608
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001609- SF bug #893549: parsing keyword arguments was broken with a few format
1610 codes.
1611
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001612- Changes donated by Elemental Security to make it work on AIX 5.3
1613 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1614 bug #105470: test_pwd fails on 64bit system (Opteron).
1615
Guido van Rossum539c6622005-09-14 17:49:54 +00001616- Changes donated by Elemental Security to make it work on HP-UX 11 on
1617 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1618
Georg Brandl4550b8d2005-08-26 06:43:52 +00001619- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001620 (fixes bug #1119418).
1621
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001622- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1623
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001624- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1625 exceptions that cause a function to exit.
1626
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001627- The implementation of set() and frozenset() was revised to use its
1628 own internal data structure. Memory consumption is reduced by 1/3
1629 and there are modest speed-ups as well. The API is unchanged.
1630
Tim Petersde7990b2005-07-17 23:45:23 +00001631- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1632
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001633- SF bug #1229429: PyObject_CallMethod failed to decrement some
1634 reference counts in some error exit cases.
1635
Tim Petersecc6e6a2005-07-10 22:30:55 +00001636- SF bug #1185883: Python's small-object memory allocator took over
1637 a block managed by the platform C library whenever a realloc specified
1638 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001639 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001640 portable way to copy data from the C-managed block into Python's
1641 small-object space without risking a memory fault. Python's small-object
1642 realloc now leaves such blocks under the control of the platform C
1643 realloc.
1644
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001645- SF bug #1232517: An overflow error was not detected properly when
1646 attempting to convert a large float to an int in os.utime().
1647
Raymond Hettinger3296e692005-06-29 23:29:56 +00001648- SF bug #1224347: hex longs now print with lowercase letters just
1649 like their int counterparts.
1650
Michael W. Hudson188d4362005-06-20 16:52:57 +00001651- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1652 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1653 interpreter states; back out that fix and do a better job (see
1654 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1655 for a longer write-up of the problem).
1656
Michael W. Hudsondf888462005-06-03 14:41:55 +00001657- SF patch #1180995: marshal now uses a binary format by default when
1658 serializing floats.
1659
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001660- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1661 the routines that promise to produce IEEE 754 binary representations
1662 of floats now simply copy bytes around.
1663
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001664- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1665 278.
1666
Brett Cannonc3647ac2005-04-26 03:45:26 +00001667- patch #1109424: int, long, float, complex, and unicode now check for the
1668 proper magic slot for type conversions when subclassed. Previously the
1669 magic slot was ignored during conversion. Semantics now match the way
1670 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001671 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001672 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001673 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001674
Barry Warsawc8d907c2005-04-19 23:43:40 +00001675- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1676 NULL, now raise an AttributeError when attempting to set or delete the
1677 attribute. Previously a TypeError was raised, but this was inconsistent
1678 with the equivalent pure-Python implementation.
1679
Michael W. Hudson774479c2005-04-18 08:46:17 +00001680- It is now safe to call PyGILState_Release() before
1681 PyEval_InitThreads() (note that if there is reason to believe there
1682 are multiple threads around you still must call PyEval_InitThreads()
1683 before using the Python API; this fix is for extension modules that
1684 have no way of knowing if Python is multi-threaded yet).
1685
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001686- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1687 disabled caused a crash.
1688
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001689- Bug #1165306: instancemethod_new allowed the creation of a method
1690 with im_class == im_self == NULL, which caused a crash when called.
1691
Tim Petersecc6e6a2005-07-10 22:30:55 +00001692- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001693 fixes the crash seen in bug #1165761
1694
Raymond Hettinger96229b12005-03-11 06:49:40 +00001695- Added two new builtins, any() and all().
1696
Brett Cannon409d8f22005-03-05 06:47:57 +00001697- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001698 (e.g., ``class C(): pass`` is no longer a syntax error).
1699 Patch #1176012 added support to the 'parser' module and 'compiler' package
1700 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001701
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001702- Patch #1115086: Support PY_LONGLONG in structmember.
1703
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001704- Bug #1155938: new style classes did not check that __init__() was
1705 returning None.
1706
Tim Petersecc6e6a2005-07-10 22:30:55 +00001707- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001708 ('\') with a specific error message.
1709
Martin v. Löwisff232d72005-03-03 09:24:38 +00001710- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1711
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001712- Bug #1124295: the __name__ attribute of file objects was
1713 inadvertently made inaccessible in restricted mode.
1714
Tim Petersecc6e6a2005-07-10 22:30:55 +00001715- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001716 an ferror() call.
1717
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001718- min() and max() now support key= arguments with the same meaning as in
1719 list.sort().
1720
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001721- The peephole optimizer now performs simple constant folding in expressions:
1722 (2+3) --> (5).
1723
Raymond Hettingera422c342005-01-11 03:03:27 +00001724- set and frozenset objects can now be marshalled. SF #1098985.
1725
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001726- Bug #1077106: Poor argument checking could cause memory corruption
1727 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001728
Jeremy Hyltonab630502005-02-04 18:44:06 +00001729- The parser did not complain about future statements in illegal
1730 positions. It once again reports a syntax error if a future
1731 statement occurs after anything other than a doc string.
1732
Neil Schemenauercf52c072005-08-12 17:34:58 +00001733- Change the %s format specifier for str objects so that it returns a
1734 unicode instance if the argument is not an instance of basestring and
1735 calling __str__ on the argument returns a unicode instance.
1736
Tim Petersf4e69282006-02-27 17:15:31 +00001737- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1738 current thread state when the auto-GIL-state machinery knows about
1739 it (since the thread state is being deleted, continuing to remember it
1740 can't help, but can hurt if another thread happens to get created with
1741 the same thread id).
1742
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001743Extension Modules
1744-----------------
1745
Georg Brandl43f08a82006-03-31 18:01:16 +00001746- Patch #1380952: fix SSL objects timing out on consecutive read()s
1747
Neal Norwitz05a45592006-03-20 06:30:08 +00001748- Patch #1309579: wait3 and wait4 were added to the posix module.
1749
Anthony Baxterfa869072006-03-20 05:21:58 +00001750- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1751 In addition, the existing ulaw code was updated.
1752
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001753- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00001754 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001755
Neal Norwitz10be10c2006-03-16 06:50:13 +00001756- Everything under lib-old was removed. This includes the following modules:
1757 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00001758 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001759 util, whatsound, whrandom, zmod

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001933- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1934 been renamed to have only a single underscore prefix. This was done to
1935 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001936
Nick Coghlan43832302006-04-23 17:04:07 +00001937- PEP 338: new module runpy defines a run_module function to support
1938 executing modules which provide access to source code or a code object
1939 via the PEP 302 import mechanisms.
1940
Anthony Baxter93f5b932006-04-03 08:05:07 +00001941- The email module's parsedate_tz function now sets the daylight savings

1949 in attribute values.
1950
Anthony Baxterc51ee692006-04-01 00:57:31 +00001951- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001952 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001953 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001954 module will not be built.
1955
Tim Petersc17976e2006-04-01 00:26:53 +00001956- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1957 aren't officially supported here, and trying to use them will probably
1958 raise an exception some day. But dicts have been allowed, and "mostly
1959 worked", so support for them won't go away without warning.
1960
Georg Brandl338ef7d2006-03-31 18:42:16 +00001961- Bug #1445068: getpass.getpass() can now be given an explicit stream

1979
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001980- email 4.0 package now integrated. This is largely the same as the email 3.0
1981 package that was included in Python 2.3, except that PEP 8 module names are
1982 now used (e.g. mail.message instead of email.Message). The MIME classes
1983 have been moved to a subpackage (e.g. email.mime.text instead of
1984 email.MIMEText). The old names are still supported for now. Several
1985 deprecated Message methods have been removed and lots of bugs have been
1986 fixed. More details can be found in the email package documentation.
1987
Walter Dörwald40108c92006-03-27 08:15:44 +00001988- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1989 (a subclass of tuple) that provides incremental decoders and encoders
1990 (a way to use stateful codecs without the stream API). Python functions
1991 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1992 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1993 have been added.

1996 a ValueError instead of a StopIteration now (like file and cString.String do).

Brett Cannon3cbd0382005-12-16 22:49:23 +00002071- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00002072 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2073 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2074 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2075 Ronald L. Rivest offered this advice for Python:
2076
2077 "The consensus of researchers in this area (at least as
2078 expressed at the NIST Hash Function Workshop 10/31/05),
2079 is that SHA-256 is a good choice for the time being, but
2080 that research should continue, and other alternatives may
2081 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002082
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002083- Added a subset of Fredrik Lundh's ElementTree package. Available

Guido van Rossumd0641422005-02-03 15:01:24 +00002242- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2243 disables recursive traversal through instance attributes, which can
2244 be exploited in various ways.
2245
Tim Peterse3547fd2005-12-16 23:13:57 +00002246- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec

2260
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002261- Enhancements to the csv module:
2262
2263 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002264 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002265 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002266 + Dialect parameter parsing has been re-implemented to improve error
2267 reporting.
2268 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2269 dictates.
2270 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002271 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002272 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002273 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2274 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002275 + reader now allows \r characters to be quoted (previously it only allowed
2276 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002277 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002278 + Dialect classes passed to the module are no longer instantiated by
2279 the module before being parsed (the former validation scheme required
2280 this, but the mechanism was unreliable).
2281 + The dialect registry now contains instances of the internal
2282 C-coded dialect type, rather than references to python objects.
2283 + the internal c-coded dialect type is now immutable.
2284 + register_dialect now accepts the same keyword dialect specifications
2285 as the reader and writer, allowing the user to register dialects
2286 without first creating a dialect class.
2287 + a configurable limit to the size of parsed fields has been added -
2288 previously, an unmatched quote character could result in the entire
2289 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002290 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002291 the parser field size limit (returning the former limit). The initial
2292 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002293 + A line_num attribute has been added to the reader object, which tracks
2294 the number of lines read from the source iterator. This is not
2295 the same as the number of records returned, as records can span
2296 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002297 + reader and writer objects were not being registered with the cyclic-GC.
2298 This has been fixed.
2299
Brett Cannone6539c42005-01-08 02:43:53 +00002300- _DummyThread objects in the threading module now delete self.__block that is
2301 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2302 lock primitives tend to be limited in number and thus should not be wasted on
2303 a _DummyThread object. Fixes bug #1089632.
2304
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002305- The imghdr module now detects Exif files.
2306
Raymond Hettinger6065d322004-12-20 23:51:53 +00002307- StringIO.truncate() now correctly adjusts the size attribute.
2308 (Bug #951915).
2309
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002310- locale.py now uses an updated locale alias table (built using
2311 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2312 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002313 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002314
Raymond Hettinger3557f422004-12-07 12:02:02 +00002315- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2316
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002317- the pickle module no longer accepts the deprecated None option in the
2318 args tuple returned by __reduce__().
2319
Brett Cannon84667c02004-12-07 03:25:18 +00002320- optparse now optionally imports gettext. This allows its use in setup.py.
2321
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002322- the pickle module no longer uses the deprecated bin parameter.
2323
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002324- the shelve module no longer uses the deprecated binary parameter.
2325
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002326- the pstats module no longer uses the deprecated ignore() method.
2327
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002328- the filecmp module no longer uses the deprecated use_statcache argument.
2329
Raymond Hettinger664347b2004-12-04 21:21:53 +00002330- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2331 extended or overridden by subclasses. Formerly, the subclassed method would
2332 be ignored by the rest of the module. (Bug #1078905).
2333
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002334- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002335 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002336
Walter Dörwald36733692004-12-22 12:50:50 +00002337- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2338 once when a size argument is given. This prevents a buffer overflow in the
2339 tokenizer with very long source lines.
2340
Barry Warsaw538561e2006-01-01 21:48:54 +00002341- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2342 immediately after creating the object, without any intervening
2343 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002344
Skip Montanaro05885812005-01-16 20:48:27 +00002345- The reconvert.quote function can now emit triple-quoted strings. The
2346 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002347
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002348- ``UserString.MutableString`` now supports negative indices in
2349 ``__setitem__`` and ``__delitem__``
2350
Greg Ward40407942005-03-05 02:53:17 +00002351- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2352 correctly.
2353
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002354- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2355 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2356 character even if the user has passed a size parameter to get a proper
2357 line ending. Remove the special handling of a "\r\n" that has been split
2358 between two lines.
2359
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002360- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2361 about illegal code points. The codec now supports PEP 293 style error
2362 handlers.
2363
Walter Dörwald78a78b02005-09-01 12:04:29 +00002364- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002365 from the input stream, so that the output is a byte string in the correct
2366 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002367
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002368- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2369 considering it exactly like a '*'.
2370
Walter Dörwald007f8df2005-10-09 19:42:27 +00002371- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2372 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002373
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002374- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2375
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002376- Patch #1413711: Certain patterns of differences were making difflib
2377 touch the recursion limit.
2378
Walter Dörwald58917a62006-03-31 15:26:22 +00002379- Bug #947906: An object oriented interface has been added to the calendar
2380 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002381 called as a script (e.g. via ``python -mcalendar``). Localized month and
2382 weekday names can be ouput (even if an exotic encoding is used) using
2383 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002384
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002385Build
2386-----
2387
Neal Norwitz602d3392006-03-31 08:21:40 +00002388- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2389 by using -mieee gcc option.
2390
Martin v. Löwis86d66262006-02-17 08:40:11 +00002391- Patch #1432345: Make python compile on DragonFly.
2392
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002393- Build support for Win64-AMD64 was added.
2394
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002395- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2396
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002397- Patch #881820: look for openpty and forkpty also in libbsd.
2398
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002399- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2400 The zlib module is now builtin on Windows.
2401
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002402- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2403
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002404- Bug #1189330: configure did not correctly determine the necessary
2405 value of LINKCC if python was built with GCC 4.0.
2406
Trent Mick8321b422005-07-26 02:29:21 +00002407- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2408 vulnerability in zlib 1.2.1 and 1.2.2.
2409
Brett Cannon08cd5982005-04-24 22:26:38 +00002410- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2411 flags that change binary compatibility. Changes were also made to
2412 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002413 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002414
Bob Ippolitoed233462005-03-29 13:47:59 +00002415- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2416 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2417 no longer exists). This configure patch makes things right.
2418
Martin v. Löwise2713be2005-03-08 15:03:08 +00002419- Bug #1158607: Build with --disable-unicode again.
2420
Brett Cannon46d96232005-02-16 00:07:19 +00002421- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2422 defined. Discovered as a result of not being able to build on OS X.
2423
Brett Cannon516592f2004-12-07 00:42:59 +00002424- setup.py now uses the directories specified in LDFLAGS using the -L option
2425 and in CPPFLAGS using the -I option for adding library and include
2426 directories, respectively, for compiling extension modules against. This has
2427 led to the core being compiled using the values in CPPFLAGS. It also removes
2428 the need for the special-casing of both DarwinPorts and Fink for darwin since
2429 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2430 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2431 Fink, ``-I/opt/local/include`` for DarwinPorts).
2432
Brett Cannon43802422005-02-10 20:48:03 +00002433- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2434 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2435 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2436 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002438C API
2439-----
2440
Tim Petersc9d78aa2006-03-26 23:27:58 +00002441- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2442 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2443 is obtained via the ``PyObject_`` family, it must be released via the
2444 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2445 always been officially true, but when Python's small-object allocator was
2446 introduced, an attempt was made to cater to a few extension modules
2447 discovered at the time that obtained memory via ``PyObject_New`` but
2448 released it via ``PyMem_DEL``. It's years later, and if such code still
2449 exists it will fail now (probably with segfaults, but calling wrong
2450 low-level memory management functions can yield many symptoms).
2451
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002452- Added a C API for set and frozenset objects.
2453
Raymond Hettinger66517482004-12-03 11:45:13 +00002454- Removed PyRange_New().
2455
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002456- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2457 mapping argument now. This string is used as a mapping table. Byte values
2458 greater than the length of the string and 0xFFFE are treated as undefined
2459 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002466
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002467- Patch #1276356: New resource "urlfetch" is implemented. This enables
