72
Georg Brandlec6c2df2006-09-11 09:38:35 +000073- Make _PyGILState_NoteThreadState() static, it was not used anywhere

372Core and builtins
373-----------------
374
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000375- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000376 compared equal or unequal to a string and a UnicodeDecodeError
377 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000378
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000379 Instead, the equal (==) and unequal (!=) comparison operators will
380 now issue a UnicodeWarning and interpret the two objects as
381 unequal. The UnicodeWarning can be filtered as desired using
382 the warning framework, e.g. silenced completely, turned into an
383 exception, logged, etc.
384
385 Note that compare operators other than equal and unequal will still
386 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000387
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000388- Fix segfault when doing string formatting on subclasses of long.
389
390- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
391 with new-style classes.
392
393- Fix bug related to __len__ functions returning negative values with
394 classic classes.
395
396- Patch #1538606, Fix __index__() clipping. There were some problems
397 discovered with the API and how integers that didn't fit into Py_ssize_t
398 were handled. This patch attempts to provide enough alternatives
399 to effectively use __index__.
400
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000401- Bug #1536021: __hash__ may now return long int; the final hash
402 value is obtained by invoking hash on the long int.
403
Thomas Hellerab1049c2006-08-08 17:37:00 +0000404- Bug #1536786: buffer comparison could emit a RuntimeWarning.
405
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000406- Bug #1535165: fixed a segfault in input() and raw_input() when
407 sys.stdin is closed.
408
Thomas Heller74d36f02006-08-04 18:17:40 +0000409- On Windows, the PyErr_Warn function is now exported from
410 the Python dll again.
411
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000412- Bug #1191458: tracing over for loops now produces a line event
413 on each iteration. Fixing this problem required changing the .pyc
414 magic number. This means that .pyc files generated before 2.5c1
415 will be regenerated.
416
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000417- Bug #1333982: string/number constants were inappropriately stored
418 in the byte code and co_consts even if they were not used, ie
419 immediately popped off the stack.
420
Georg Brandle9462c72006-08-04 18:03:37 +0000421- Fixed a reference-counting problem in property().
422

424Library
425-------
426
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000427- Fix a bug in the ``compiler`` package that caused invalid code to be
428 generated for generator expressions.
429
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000430- The distutils version has been changed to 2.5.0. The change to
431 keep it programmatically in sync with the Python version running
432 the code (introduced in 2.5b3) has been reverted. It will continue
433 to be maintained manually as static string literal.
434
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000435- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000436 and this cannot be converted to the required C type, an exception is
437 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000438 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000439
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000440- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000441 an exception.
442
Tim Petersc10c9d02006-09-05 02:18:09 +0000443- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000444 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000445 workarounds for clocks with low resolution, to stop the code yielding
446 duplicate UUIDs.
447
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000448- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
449 before raising SystemExit, allowing IDLE to honor quit() and exit().
450
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000451- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
452
Georg Brandl7a1af772006-08-14 21:55:28 +0000453- Patch #1536071: trace.py should now find the full module name of a
454 file correctly even on Windows.
455
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000456- logging's atexit hook now runs even if the rest of the module has
457 already been cleaned up.
458
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000459- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000460
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000461- Bug #1531405, format_exception no longer raises an exception if
462 str(exception) raised an exception.
463
Neil Schemenauer06ded092006-08-04 16:20:30 +0000464- Fix a bug in the ``compiler`` package that caused invalid code to be
465 generated for nested functions.

Georg Brandl3335a7a2006-08-14 21:42:55 +0000473- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
474 raises the correct exceptions.
475
Thomas Heller1ce433e2006-08-14 16:20:04 +0000476- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
477 '-no-stack-protector' compiler flag for OpenBSD has been removed.
478
Thomas Heller86720042006-08-14 11:17:48 +0000479- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
480 uses the _as_parameter_ attribute when objects are passed to foreign
481 function calls. The ctypes version number was changed to 1.0.1.
482
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000483- Bug #1530559, struct.pack raises TypeError where it used to convert.
484 Passing float arguments to struct.pack when integers are expected
485 now triggers a DeprecationWarning.
486
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000487

535Core and builtins
536-----------------
537
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000538- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000539 returned a long (see PEP 353).
540
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000541- Bug #1515471: string.replace() accepts character buffers again.
542
Neal Norwitz07aadb12006-07-30 06:55:48 +0000543- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
544 This provides the proper warning for struct.pack().
545 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
546
Neal Norwitz0d62a062006-07-30 06:53:31 +0000547- Patch #1531113: Fix augmented assignment with yield expressions.
548 Also fix a SystemError when trying to assign to yield expressions.
549
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000550- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
551 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
552 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
553 excessive filesystem operations during imports.
554
Tim Petersbc24eee2006-07-27 01:14:53 +0000555- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
556 operations on signed longs that are formally undefined by C.
557 Unfortunately, at least one compiler now cares about that, so complicated
558 the code to make that compiler happy again.
559
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000560- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
561
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000562- Patch #1232023: Stop including current directory in search
563 path on Windows.
564
Neal Norwitze1fdb322006-07-21 05:32:28 +0000565- Fix some potential crashes found with failmalloc.
566
Neal Norwitze7563102006-07-17 01:00:16 +0000567- Fix warnings reported by Klocwork's static analysis tool.
568
Neal Norwitz84be93b2006-07-16 01:50:38 +0000569- Bug #1512814, Fix incorrect lineno's when code within a function
570 had more than 255 blank lines.
571
Georg Brandl9dceedb2006-07-12 15:31:17 +0000572- Patch #1521179: Python now accepts the standard options ``--help`` and
573 ``--version`` as well as ``/?`` on Windows.
574
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000575- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000576 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000577 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000578
Tim Peters112aad32006-07-19 00:03:19 +0000579- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000580 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000581 new ``sys._current_frames()`` returns a dictionary with one entry,
582 mapping the faux "thread id" 0 to the current frame.
583
Ronald Oussoren3075e162006-07-25 20:28:55 +0000584- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

589
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000590- Correction of patch #1455898: In the mbcs decoder, set final=False
591 for stream decoder, but final=True for the decode function.
592
Georg Brandl07fec3a2006-08-01 18:49:24 +0000593- os.urandom no longer masks unrelated exceptions like SystemExit or
594 KeyboardInterrupt.
595
Tim Peters4643c2f2006-08-10 22:45:34 +0000596- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000597 shutil.copytree on Windows
598
Georg Brandle34ac7c2006-07-30 11:07:23 +0000599- Bug #1002398: The documentation for os.path.sameopenfile now correctly
600 refers to file descriptors, not file objects.
601
Tim Petersc10c9d02006-09-05 02:18:09 +0000602- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000603 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000604 #1513611, and probably others.
605
Georg Brandledd9b0d2006-07-29 09:33:26 +0000606- Bug #1441397: The compiler module now recognizes module and function
607 docstrings correctly as it did in Python 2.4.
608
Tim Peters6f681472006-07-27 23:44:37 +0000609- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
610 lost that tests are sorted by name before being run. This rarely
611 matters for well-written tests, but can create baffling symptoms if
612 side effects from one test to the next affect outcomes. ``DocTestFinder``
613 has been changed to sort the list of tests it returns.
614
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000615- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000616 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000617
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000618- Bug #978833: Really close underlying socket in _socketobject.close.
619
Georg Brandl8c036cc2006-08-20 13:15:39 +0000620- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
621 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000622
Georg Brandlcf0c1722006-07-26 07:23:32 +0000623- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
624 to recursive calls and call it with the failing package name.
625
Martin v. Löwis0b483032006-07-25 09:53:12 +0000626- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
627
Georg Brandlc13c34c2006-07-24 14:09:56 +0000628- Patch #1515343: Fix printing of deprecated string exceptions with a
629 value in the traceback module.
630
Greg Ward48fae7a2006-07-23 16:05:51 +0000631- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
632
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000633- Patch #1524429: Use repr() instead of backticks in Tkinter again.
634
Brett Cannoncaebe222006-07-18 04:41:36 +0000635- Bug #1520914: Change time.strftime() to accept a zero for any position in its
636 argument tuple. For arguments where zero is illegal, the value is forced to
637 the minimum value that is correct. This is to support an undocumented but
638 common way people used to fill in inconsequential information in the time
639 tuple pre-2.4.
640
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000641- Patch #1220874: Update the binhex module for Mach-O.
642
Barry Warsawb110bad2006-07-21 14:51:07 +0000643- The email package has improved RFC 2231 support, specifically for
644 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
645 (name*0=<blah>) parameter continuations. This may change the types of
646 values returned from email.message.Message.get_param() and friends.
647 Specifically in some cases where non-encoded continuations were used,
648 get_param() used to return a 3-tuple of (None, None, string) whereas now it
649 will just return the string (since non-encoded continuations don't have
650 charset and language parts).
651
652 Also, whereas % values were decoded in all parameter continuations, they are
653 now only decoded in encoded parameter parts.
654
Ronald Oussoren3075e162006-07-25 20:28:55 +0000655- Bug #1517990: IDLE keybindings on MacOS X now work correctly
656
657- Bug #1517996: IDLE now longer shows the default Tk menu when a
658 path browser, class browser or debugger is the frontmost window on MacOS X
659
Barry Warsaw00decd72006-07-27 23:43:15 +0000660- Patch #1520294: Support for getset and member descriptors in types.py,
661 inspect.py, and pydoc.py. Specifically, this allows for querying the type
662 of an object against these built-in types and more importantly, for getting
663 their docstrings printed in the interactive interpreter's help() function.

667-----------------
668
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000669- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
670 a socket operation on a socket with a timeout, the exception will be
671 caught correctly. Previously, the exception was not caught.
672
Thomas Heller1393d6a2006-07-28 21:43:20 +0000673- Patch #1529514: The _ctypes extension is now compiled on more
674 openbsd target platforms.
675
Tim Peters9cab5932006-07-28 00:30:00 +0000676- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
677 a memory leak, affecting pickles and deep copies.
678
Tim Petersbc24eee2006-07-27 01:14:53 +0000679- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

681
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000682- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
683
Thomas Hellerce049a02006-07-14 17:51:14 +0000684- Patch #1521817: Index range checking on ctypes arrays containing
685 exactly one element enabled again. This allows iterating over these
686 arrays, without the need to check the array size before.
687
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000688- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000689 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000690 /dev/null in certain cases; this is now fixed.
691
Thomas Heller47d7a062006-07-12 08:43:47 +0000692- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
693 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000694
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000695- Because of a misspelled preprocessor symbol, ctypes was always
696 compiled without thread support; this is now fixed.
697
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000698- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
699 methods now allow their database parameter to be None as the
700 sleepycat API allows.
701
Matt Flemingec926502006-07-28 11:27:27 +0000702- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
703 bluetooth API compared with Linux and FreeBSD.
704
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000705Tests
706-----
707
708- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
709 how long the test file should take to play. Now accepts taking 2.93 secs
710 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
711
Georg Brandl4793aa32006-07-28 18:31:39 +0000712- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
713 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
714 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +0000721Mac
722---
723
724- PythonLauncher now works correctly when the path to the script contains
725 characters that are treated specially by the shell (such as quotes).
726
727- Bug #1527397: PythonLauncher now launches scripts with the working directory
728 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000729 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000730 expect.

738Core and builtins
739-----------------
740
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000741- Bug #1441486: The literal representation of -(sys.maxint - 1)
742 again evaluates to a int object, not a long.
743
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000744- Bug #1501934: The scope of global variables that are locally assigned
745 using augmented assignment is now correctly determined.
746
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000747- Bug #927248: Recursive method-wrapper objects can now safely
748 be released.
749
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000750- Bug #1417699: Reject locale-specific decimal point in float()
751 and atof().
752
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000753- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
754 omit a default "error" argument for NULL pointer. This allows
755 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000756
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000757- Bug #1519018: 'as' is now validated properly in import statements.
758
Neal Norwitz28746ab2006-07-09 22:14:42 +0000759- On 64 bit systems, int literals that use less than 64 bits are
760 now ints rather than longs.
761
Neal Norwitzed657552006-07-10 00:04:44 +0000762- Bug #1512814, Fix incorrect lineno's when code at module scope
763 started after line 256.
764
Tim Peters32a83612006-07-10 21:08:24 +0000765- New function ``sys._current_frames()`` returns a dict mapping thread
766 id to topmost thread stack frame. This is for expert use, and is
767 especially useful for debugging application deadlocks. The functionality
768 was previously available in Fazal Majid's ``threadframe`` extension
769 module, but it wasn't possible to do this in a wholly threadsafe way from
770 an extension.

787
Thomas Woutersadd19112006-07-05 11:03:49 +0000788- string.Template() now correctly handles tuple-values. Previously,
789 multi-value tuples would raise an exception and single-value tuples would
790 be treated as the value they contain, instead.
791
Martin v. Löwisede77f52006-07-03 13:01:35 +0000792- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

805 is created.
806

811 attribute values.
812
813- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
814 sgmllib ('[' and ']' were not accepted).
815
Georg Brandl1be63af2006-06-28 20:23:25 +0000816- Fix a bug in the turtle module's end_fill function.
817
Brett Cannon53ab5b72006-06-22 16:49:14 +0000818- Bug #1510580: The 'warnings' module improperly required that a Warning
819 category be either a types.ClassType and a subclass of Warning. The proper
820 check is just that it is a subclass with Warning as the documentation states.
821
Georg Brandlad29e632006-06-21 17:45:17 +0000822- The compiler module now correctly compiles the new try-except-finally
823 statement (bug #1509132).
824
Neal Norwitz60373cd2006-06-22 06:30:50 +0000825- The wsgiref package is now installed properly on Unix.
826
Vinay Sajip28e57612006-07-01 10:45:20 +0000827- A bug was fixed in logging.config.fileConfig() which caused a crash on
828 shutdown when fileConfig() was called multiple times.
829
Gerhard Häring762fbd32006-07-02 17:48:30 +0000830- The sqlite3 module did cut off data from the SQLite database at the first
831 null character before sending it to a custom converter. This has been fixed
832 now.

835-----------------
836
Tim Peters112aad32006-07-19 00:03:19 +0000837- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
838 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
839 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000840
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000841- Assigning None to pointer type fields in ctypes structures possible
842 overwrote the wrong fields, this is fixed now.
843
844- Fixed a segfault in _ctypes when ctypes.wintypes were imported
845 on non-Windows platforms.
846
847- Bug #1518190: The ctypes.c_void_p constructor now accepts any
848 integer or long, without range checking.
849
850- Patch #1517790: It is now possible to use custom objects in the ctypes
851 foreign function argtypes sequence as long as they provide a from_param
852 method, no longer is it required that the object is a ctypes type.
853
854- The '_ctypes' extension module now works when Python is configured
855 with the --without-threads option.
856
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000857- Bug #1513646: os.access on Windows now correctly determines write

872
Tim Peters32a83612006-07-10 21:08:24 +0000873- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000874 Previously, the slight difference could cause compilation errors of the
875 'zlib' module on systems with more than one version of zlib.
876
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000877- The MSI compileall step was fixed to also support a TARGETDIR

Anthony Baxter51bcb682006-04-05 14:51:42 +0000907
908Core and builtins
909-----------------
910
Georg Brandla56b9152006-06-19 06:35:54 +0000911- Patch #1507676: Error messages returned by invalid abstract object operations
912 (such as iterating over an integer) have been improved and now include the
913 type of the offending object to help with debugging.
914
Brett Cannonea3912b2006-06-13 21:46:41 +0000915- Bug #992017: A classic class that defined a __coerce__() method that returned
916 its arguments swapped would infinitely recurse and segfault the interpreter.
917
Neal Norwitz909eb122006-06-12 02:13:21 +0000918- Fix the socket tests so they can be run concurrently.
919
Neal Norwitzb9845e72006-06-12 02:11:18 +0000920- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000921 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000922
Brett Cannon22565aa2006-06-09 22:31:23 +0000923- Bug #532646: object.__call__() will continue looking for the __call__
924 attribute on objects until one without one is found. This leads to recursion
925 when you take a class and set its __call__ attribute to an instance of the
926 class. Originally fixed for classic classes, but this fix is for new-style.
927 Removes the infinite_rec_3 crasher.
928
Georg Brandl24250812006-06-09 18:45:48 +0000929- The string and unicode methods startswith() and endswith() now accept
930 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
931
Brett Cannonde3b0522006-06-08 17:00:45 +0000932- Buffer objects, at the C level, never used the char buffer
933 implementation even when the char buffer for the wrapped object was
934 explicitly requested (originally returned the read or write buffer).
935 Now a TypeError is raised if the char buffer is not present but is
936 requested.
937
Georg Brandlddbaa662006-06-04 21:56:52 +0000938- Patch #1346214: Statements like "if 0: suite" are now again optimized
939 away like they were in Python 2.4.
940
Georg Brandlb7c8f542006-05-27 12:30:25 +0000941- Builtin exceptions are now full-blown new-style classes instead of
942 instances pretending to be classes, which speeds up exception handling
943 by about 80% in comparison to 2.5a2.
944
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000945- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
946 Unicode 4.1.
947
Georg Brandlf4ef1162006-05-26 18:03:31 +0000948- Patch #921466: sys.path_importer_cache is now used to cache valid and
949 invalid file paths for the built-in import machinery which leads to
950 fewer open calls on startup.
951
Tim Peters696cf432006-05-24 21:10:40 +0000952- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
953 of-2 bases. The largest speedup is for inputs with about 1000 decimal
954 digits. Conversion from non-power-of-2 bases remains quadratic-time in
955 the number of input digits (it was and remains linear-time for bases
956 2, 4, 8, 16 and 32).
957
Tim Petersb713ec22006-05-23 18:45:30 +0000958- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
959 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
960 an integer close to ``sys.maxint``. This was repaired by patch
961 #1335972, which also gives a nice speedup.
962
Richard Jonescebbefc2006-05-23 18:28:17 +0000963- Patch #1337051: reduced size of frame objects.
964
965- PyErr_NewException now accepts a tuple of base classes as its
966 "base" parameter.
967
Richard Jones7c88dcc2006-05-23 10:37:38 +0000968- Patch #876206: function call speedup by retaining allocated frame
969 objects.
970
Georg Brandl7b90e162006-05-18 07:01:27 +0000971- Bug #1462152: file() now checks more thoroughly for invalid mode
972 strings and removes a possible "U" before passing the mode to the
973 C library function.
974
Neal Norwitz1004a532006-05-15 07:17:23 +0000975- Patch #1488312, Fix memory alignment problem on SPARC in unicode
976
Neal Norwitz373f0a72006-05-15 07:04:36 +0000977- Bug #1487966: Fix SystemError with conditional expression in assignment
978
Martin v. Löwis879768d2006-05-11 13:28:43 +0000979- WindowsError now has two error code attributes: errno, which carries
980 the error values from errno.h, and winerror, which carries the error
981 values from winerror.h. Previous versions put the winerror.h values
982 (from GetLastError()) into the errno attribute.
983
Martin v. Löwis77736712006-05-04 05:51:03 +0000984- Patch #1475845: Raise IndentationError for unexpected indent.
985
Neal Norwitzc4edb0e2006-05-02 04:43:14 +0000986- Patch #1479181: split open() and file() from being aliases for each other.
987
Tim Peters44bd9862006-06-01 13:49:23 +0000988- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
989 methods were always silently ignored by dictionaries when comparing keys.
990 They are now passed through (except when using the C API function
991 ``PyDict_GetItem()``, whose semantics did not change).
992
993- Bug #1456209: In some obscure cases it was possible for a class with a
994 custom ``__eq__()`` method to confuse dict internals when class instances
995 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
996 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +0000998Extension Modules
999-----------------
1000
Trent Mick960a3f82006-06-28 20:30:41 +00001001- Bug #1295808: expat symbols should be namespaced in pyexpat
1002
1003- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1004
Brett Cannon6ee7d012006-06-08 16:23:04 +00001005- Change binascii.hexlify to accept a read-only buffer instead of only a char
1006 buffer and actually follow its documentation.
1007
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001008- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1009
Nick Coghlanc649ec52006-05-29 12:43:05 +00001010- Patch #1478788 (modified version): The functional extension module has
1011 been renamed to _functools and a functools Python wrapper module added.
1012 This provides a home for additional function related utilities that are
1013 not specifically about functional programming. See PEP 309.
1014
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001015- Patch #1493701: performance enhancements for struct module.
1016
Georg Brandl378d5922006-05-17 14:26:50 +00001017- Patch #1490224: time.altzone is now set correctly on Cygwin.
1018
Georg Brandl8d3342b2006-05-16 07:38:27 +00001019- Patch #1435422: zlib's compress and decompress objects now have a
1020 copy() method.
1021
Andrew MacIntyre92913322006-06-13 15:04:24 +00001022- Patch #1454481: thread stack size is now tunable at runtime for thread
1023 enabled builds on Windows and systems with Posix threads support.
1024
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001025- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1026 (up to the system limit of 32K characters).
1027
1028- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1029 As a result, these functions now raise WindowsError instead of OSError.
1030
Tim Peters7a822da2006-05-25 21:50:17 +00001031- ``time.clock()`` on Win64 should use the high-performance Windows
1032 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1033 Windows platforms).
1034
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001035- Calling Tk_Init twice is refused if the first call failed as that
1036 may deadlock.
1037
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001038- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1039 accept it without potentially using an uninitialized pointer.
1040
1041- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1042 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1043 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001044
Gregory P. Smith372b5832006-06-05 18:48:21 +00001045- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001046 [pybsddb project SF patch number 1466734]
1047
Gregory P. Smith372b5832006-06-05 18:48:21 +00001048- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1049 parameter is supplied. [SF pybsddb bug #1477863]
1050
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001051- bsddb: the __len__ method of a DB object has been fixed to return correct
1052 results. It could previously incorrectly return 0 in some cases.
1053 Fixes SF bug 1493322 (pybsddb bug 1184012).
1054
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001055- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1056 aborts the db transaction safely when a modifier callback fails.
1057 Fixes SF python patch/bug #1408584.
1058
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001059- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001060 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001061 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1062 database calls that would previously deadlock. [SF python bug #775414]
1063
Vinay Sajip28e57612006-07-01 10:45:20 +00001064- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001065

1071
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001072- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1073 functions.
1074
Martin v. Löwis3798da02006-06-17 18:44:27 +00001075- Patch #812986: Update turtle output even if not tracing.
1076
Vinay Sajip28e57612006-07-01 10:45:20 +00001077- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001078 Tkinter.BaseWidget.
1079
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001080- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1081
Martin v. Löwis337487e2006-06-17 09:15:14 +00001082- Patch #763580: Add name and value arguments to Tkinter variable
1083 classes.
1084
Georg Brandl83cc0d02006-06-14 08:50:03 +00001085- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1086 mime.types file for determining MIME types.
1087
Georg Brandl2605ca82006-06-14 06:08:31 +00001088- Bug #1339007: Shelf objects now don't raise an exception in their
1089 __del__ method when initialization failed.
1090
Martin v. Löwisd8251432006-06-14 05:21:04 +00001091- Patch #1455898: The MBCS codec now supports the incremental mode for
1092 double-byte encodings.
1093
Tim Peters43898b42006-06-14 04:09:25 +00001094- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1095 guarantee that adjacent triples in the return list always describe
1096 non-adjacent blocks. Previously, a pair of matching blocks could end
1097 up being described by multiple adjacent triples that formed a partition
1098 of the matching pair.
1099
Greg Ward0e0c9f42006-06-11 16:24:11 +00001100- Bug #1498146: fix optparse to handle Unicode strings in option help,
1101 description, and epilog.
1102
Greg Wardd1c797e2006-06-11 14:42:41 +00001103- Bug #1366250: minor optparse documentation error.
1104
Greg Ward7f547402006-06-11 00:40:49 +00001105- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1106 clarify docs.
1107
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001108- The wsgiref package has been added to the standard library.
1109
Nick Coghlan676725d2006-06-08 13:54:49 +00001110- The functions update_wrapper() and wraps() have been added to the functools
1111 module. These make it easier to copy relevant metadata from the original
1112 function when writing wrapper functions.
1113
Tim Petersd6a9eef2006-06-05 01:48:21 +00001114- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1115 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001116
Martin v. Löwis3f767792006-06-04 19:36:28 +00001117- Patch #1359618: Speed up charmap encoder by using a trie structure
1118 for lookup.
1119
Tim Petersd609b1a2006-06-02 23:22:51 +00001120- The functions in the ``pprint`` module now sort dictionaries by key
1121 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1122 if and only if its display required more than one line, although that
1123 wasn't documented. The new behavior increases predictability; e.g.,
1124 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1125
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001126- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1127 (thanks for J. J. Lee).
1128
Georg Brandl2b330372006-05-28 20:23:12 +00001129- Patch #1496206: improve urllib2 handling of passwords with respect to
1130 default HTTP and HTTPS ports.
1131
George Yoshidaf3c65de2006-05-28 16:39:09 +00001132- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1133
Bob Ippolito7298f272006-05-23 18:43:47 +00001134- Patch #1281707: speed up gzip.readline.
1135
Georg Brandlb89316f2006-05-17 15:51:16 +00001136- Patch #1180296: Two new functions were added to the locale module:
1137 format_string() to get the effect of "format % items" but locale-aware,
1138 and currency() to format a monetary number with currency sign.
1139
Georg Brandle3a25832006-05-17 14:56:04 +00001140- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1141 and several features added, such as speed and geometry control.
1142
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001143- Patch #1488881: add support for external file objects in bz2 compressed
1144 tarfiles.
1145
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001146- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1147 stdout arguments, making it possible to redirect input and output
1148 for remote debugging.
1149
1150- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1151 a couple of issues, notably handling of long file names using the
1152 GNU LONGNAME extension.
1153
1154- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1155 new flag when ``name`` is already the name of an option flag.
1156
1157- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1158 package.
1159
1160- Patch #1472854: make the rlcompleter.Completer class usable on non-
1161 UNIX platforms.
1162
1163- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1164
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001165- Bug #1472827: correctly escape newlines and tabs in attribute values in
1166 the saxutils.XMLGenerator class.

Thomas Heller1b046642006-04-18 18:51:06 +00001204- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1205 by converting these apis from macros into exported functions again:
1206
1207 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile

Martin v. Löwis45294a92006-04-18 06:24:08 +00001213- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1214
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001215- All uses of PyStructSequence_InitType have been changed to initialize
1216 the type objects only once, even if the interpreter is initialized
1217 multiple times.
1218
Neal Norwitz61546162006-04-14 05:20:28 +00001219- Bug #1454485, array.array('u') could crash the interpreter. This was
1220 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1221 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1222
1223- Py_UNICODE is unsigned. It was always documented as unsigned, but
1224 due to a bug had a signed value in previous versions.
1225
Tim Peters3a5e8b12006-04-11 01:44:07 +00001226- Patch #837242: ``id()`` of any Python object always gives a positive
1227 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1228 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001229 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001230 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001231
Tim Peters3a5e8b12006-04-11 01:44:07 +00001232 def __hash__(self):
1233 return id(self) # WRONG
1234
1235 because a hash result must be a (short) Python int but it was always
1236 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001237 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001238 was always usable as a hash value before this patch. That's no longer
1239 necessarily so.
1240
1241- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001242 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001243 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001244 #1454844)
1245
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001246- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1247 involving generators that have paused outside of any ``try`` or ``with``
1248 blocks. (In 2.5a1, a paused generator that was part of a reference
1249 cycle could not be garbage collected, regardless of whether it was
1250 paused in a ``try`` or ``with`` block.)

1254
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001255- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1256 is a macro.
1257
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001258- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1259 fails with an error condition.
1260
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001261- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1262
1263- Bug #1117761: bsddb.*open() no longer raises an exception when using
1264 the cachesize parameter.
1265
1266- Bug #1149413: bsddb.*open() no longer raises an exception when using
1267 a temporary db (file=None) with the 'n' flag to truncate on open.
1268
1269- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1270 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001271
Armin Rigoa9017c32006-04-19 11:50:27 +00001272- Patch #1062014: AF_UNIX sockets under Linux have a special
1273 abstract namespace that is now fully supported.
1274
Anthony Baxter51bcb682006-04-05 14:51:42 +00001275Library
1276-------
1277
Peter Astrand7d1d4362006-07-14 14:04:45 +00001278- Bug #1223937: subprocess.CalledProcessError reports the exit status
1279 of the process using the returncode attribute, instead of
1280 abusing errno.
1281
Tim Peters711bf302006-04-25 03:31:36 +00001282- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1283 a doctest to be skipped (the code is not run, and the expected output
1284 or exception is ignored).
1285
Nick Coghlanda2268f2006-04-24 04:37:15 +00001286- Fixed contextlib.nested to cope with exceptions being raised and
1287 caught inside exit handlers.
1288
Greg Wardab05edc2006-04-23 03:47:58 +00001289- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1290 hex, octal, or binary; add ``append_const`` action; keep going if
1291 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1292 added ``epilog`` for better help generation).
1293
Tim Peters21fbd572006-04-21 21:18:10 +00001294- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1295 called from a thread spawned as a side effect of importing a module.
1296
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001297- The pydoc module now supports documenting packages contained in
1298 .zip or .egg files.
1299
1300- The pkgutil module now has several new utility functions, such
1301 as ``walk_packages()`` to support working with packages that are either
1302 in the filesystem or zip files.
1303
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001304- The mailbox module can now modify and delete messages from
1305 mailboxes, in addition to simply reading them. Thanks to Gregory
1306 K. Johnson for writing the code, and to the 2005 Google Summer of
1307 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001308
Tim Petersc7605f22006-04-17 21:12:33 +00001309- The ``__del__`` method of class ``local`` in module ``_threading_local``
1310 returned before accomplishing any of its intended cleanup.
1311

1317
Anthony Baxtere29002c2006-04-12 12:07:31 +00001318- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1319 Windows. Bug #1469163.
1320
Phillip J. Eby47032112006-04-11 01:07:43 +00001321- The warnings, linecache, inspect, traceback, site, and doctest modules
1322 were updated to work correctly with modules imported from zipfiles or
1323 via other PEP 302 __loader__ objects.
1324
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001325- Patch #1467770: Reduce usage of subprocess._active to processes which
1326 the application hasn't waited on.

1331
Skip Montanaro262fb922006-04-21 02:31:07 +00001332- The pstats.Stats class accepts an optional stream keyword argument to
1333 direct output to an alternate file-like object.
1334
Anthony Baxter51bcb682006-04-05 14:51:42 +00001335Build
1336-----
1337
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001338- The Makefile now has a reindent target, which runs reindent.py on
1339 the library.
1340
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001341- Patch #1470875: Building Python with MS Free Compiler
1342
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001343- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001344
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001345- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1346 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001347 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001348 CXX from --with-cxx-main, see description in README.
1349
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001350- Patch #1429775: Link extension modules with the shared libpython.
1351
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001352- Fixed a libffi build problem on MIPS systems.
1353
Tim Peters8931ff12006-05-13 23:28:20 +00001354- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1355 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1356 and "%zu" for unsigned integers of type ``size_t``.
1357
Anthony Baxter51bcb682006-04-05 14:51:42 +00001358Tests
1359-----
1360
Nick Coghlanda2268f2006-04-24 04:37:15 +00001361- test_contextlib now checks contextlib.nested can cope with exceptions
1362 being raised and caught inside exit handlers.
1363
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001364- test_cmd_line now checks operation of the -m and -c command switches
1365
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001366- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1367 it separately and by hand. It also wasn't cleaning up its changes to
1368 the current Decimal context.
1369
Thomas Woutersabd08882006-04-26 15:53:30 +00001370- regrtest.py now has a -M option to run tests that test the new limits of
1371 containers, on 64-bit architectures. Running these tests is only sensible
1372 on 64-bit machines with more than two gigabytes of memory. The argument
1373 passed is the maximum amount of memory for the tests to use.

1382-------------
1383
Tim Petersb06d28c2006-05-12 01:57:59 +00001384- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1385
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001386- PEP 343: Added Context Types section to the library reference
1387 and attempted to bring other PEP 343 related documentation into
1388 line with the implementation and/or python-dev discussions.
1389
Tim Peters8dc73d22006-04-24 02:03:16 +00001390- Bug #1337990: clarified that ``doctest`` does not support examples
1391 requiring both expected output and an exception.

Anthony Baxterebed3f62006-04-03 15:03:44 +00001397*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001398
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001399Core and builtins
1400-----------------
1401
Nick Coghlan43832302006-04-23 17:04:07 +00001402- PEP 338: -m command line switch now delegates to runpy.run_module
1403 allowing it to support modules in packages and zipfiles
1404
Martin v. Löwisc661b882006-04-20 04:54:23 +00001405- On Windows, .DLL is not an accepted file name extension for
1406 extension modules anymore; extensions are only found if they
1407 end in .PYD.
1408
Martin v. Löwisea62d252006-04-03 10:56:49 +00001409- Bug #1421664: sys.stderr.encoding is now set to the same value as
1410 sys.stdout.encoding.
1411
Neal Norwitz92e212f2006-04-03 04:48:37 +00001412- __import__ accepts keyword arguments.
1413
Georg Brandlccadf842006-03-31 18:54:53 +00001414- Patch #1460496: round() now accepts keyword arguments.
1415
Anthony Baxter262c00a2006-03-30 10:53:17 +00001416- Fixed bug #1459029 - unicode reprs were double-escaped.
1417
Hye-Shik Changd478f342006-03-23 12:32:36 +00001418- Patch #1396919: The system scope threads are reenabled on FreeBSD
1419 5.4 and later versions.
1420
Neal Norwitze98ccf62006-03-23 05:39:47 +00001421- Bug #1115379: Compiling a Unicode string with an encoding declaration
1422 now gives a SyntaxError.
1423
Georg Brandlabd1ff82006-03-18 07:59:59 +00001424- Previously, Python code had no easy way to access the contents of a
1425 cell object. Now, a ``cell_contents`` attribute has been added
1426 (closes patch #1170323).
1427
Tim Peterscf79aac2006-03-16 01:14:46 +00001428- Patch #1123430: Python's small-object allocator now returns an arena to
1429 the system ``free()`` when all memory within an arena becomes unused
1430 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1431 freed. Some applications will see a drop in virtual memory size now,
1432 especially long-running applications that, from time to time, temporarily
1433 use a large number of small objects. Note that when Python returns an
1434 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001435 platform C library will in turn return that memory to the operating system.
1436 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001437 appears to be effective at least on Microsoft C and gcc-based systems.
1438 Thanks to Evan Jones for hard work and patience.
1439
Georg Brandl533ff6f2006-03-08 18:09:27 +00001440- Patch #1434038: property() now uses the getter's docstring if there is
1441 no "doc" argument given. This makes it possible to legitimately use
1442 property() as a decorator to produce a read-only property.
1443
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001444- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1445 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1446 of requiring an int or long in slicing and a few other contexts, enabling
1447 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1448
Neal Norwitz995acdf2006-03-07 05:01:00 +00001449- Fixed various bugs reported by Coverity's Prevent tool.
1450
Brett Cannonbf364092006-03-01 04:25:17 +00001451- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1452 new exception base class, BaseException, which has a new message attribute.
1453 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1454 Raising a string exception now raises a DeprecationWarning.
1455
Thomas Woutersfb609f42006-02-28 16:37:25 +00001456- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1457 explicitly relative, using 'from .module import name' to mean 'from the same
1458 package as this module is in. Imports without dots still default to the
1459 old relative-then-absolute, unless 'from __future__ import
1460 absolute_import' is used.
1461
Brett Cannona7446e32006-02-27 23:39:10 +00001462- Properly check if 'warnings' raises an exception (usually when a filter set
1463 to "error" is triggered) when raising a warning for raising string
1464 exceptions.
1465
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001466- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001467 The name was removed from Include/code.h.
1468
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001469- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001470
Guido van Rossum1968ad32006-02-25 22:38:04 +00001471- Patch 1433928:
1472 - The copy module now "copies" function objects (as atomic objects).
1473 - dict.__getitem__ now looks for a __missing__ hook before raising
1474 KeyError.
1475
Tim Peters84ef21c2006-02-28 20:39:06 +00001476- PEP 343: with statement implemented. Needs ``from __future__ import
1477 with_statement``. Use of 'with' as a variable will generate a warning.
1478 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001479 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001480 The following objects have __context__ methods:
1481 - The built-in file type.
1482 - The thread.LockType type.
1483 - The following types defined by the threading module:
1484 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1485 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001486
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001487- Fix the encodings package codec search function to only search
1488 inside its own package. Fixes problem reported in patch #1433198.
1489
1490 Note: Codec packages should implement and register their own
1491 codec search function. PEP 100 has the details.
1492
Tim Peters9ea89d22006-06-04 03:26:02 +00001493- PEP 353: Using ``Py_ssize_t`` as the index type.
1494
1495- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1496 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1497 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1498 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1499 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001500
Neal Norwitzfc76d632006-01-10 06:03:13 +00001501- Patch #1400181, fix unicode string formatting to not use the locale.
1502 This is how string objects work. u'%f' could use , instead of .
1503 for the decimal point. Now both strings and unicode always use periods.
1504
Neal Norwitz671b9e32006-01-09 07:07:12 +00001505- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1506 configure would break checking curses.h.
1507
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001508- Bug #959576: The pwd module is now builtin. This allows Python to be
1509 built on UNIX platforms without $HOME set.
1510
Neal Norwitzc10978f2005-12-19 06:07:16 +00001511- Bug #1072182, fix some potential problems if characters are signed.
1512
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001513- Bug #889500, fix line number on SyntaxWarning for global declarations.
1514
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001515- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1516
Neal Norwitze7214a12005-12-18 05:03:17 +00001517- Support for converting hex strings to floats no longer works.
1518 This was not portable. float('0x3') now raises a ValueError.
1519
Barry Warsaw2a38a862005-12-18 01:27:35 +00001520- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001521 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001522 is now displayed in interactive prompt banner.
1523
Georg Brandlfa166682005-12-17 21:45:17 +00001524- Implementation of PEP 341 - Unification of try/except and try/finally.
1525 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001526 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001527
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001528- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1529 now encodes backslash correctly.
1530
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001531- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1532
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001533- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001534 and long longs.
1535
Neal Norwitz67715f02005-11-09 06:59:35 +00001536- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001537 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001538 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001539
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001540- Replaced most Unicode charmap codecs with new ones using the
1541 new Unicode translate string feature in the builtin charmap
1542 codec; the codecs were created from the mapping tables available
1543 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1544 encodings now include a mapping for the Apple logo)
1545
Tim Peterse3547fd2005-12-16 23:13:57 +00001546- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001547
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001548- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001549
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001550- A new AST parser implementation was completed. The abstract
1551 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001552 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001553
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001554- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001555 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1556
Neal Norwitz708e51a2005-10-03 04:48:15 +00001557- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1558
Neal Norwitz11bd1192005-10-03 00:54:56 +00001559- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1560 Provide a warning when a directory is passed on the command line.
1561
Neal Norwitz40d37812005-10-02 01:48:49 +00001562- Fix segfault with invalid coding.
1563
1564- SF bug #772896: unknown encoding results in MemoryError.
1565
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001566- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001567 supported a __len__() method which evaluated to False when the iterator
1568 was empty.
1569
Guido van Rossum630db602005-09-20 18:49:54 +00001570- On 64-bit platforms, when __len__() returns a value that cannot be
1571 represented as a C int, raise OverflowError.
1572
Skip Montanarof8948ca2005-09-19 03:54:46 +00001573- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001574 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001575
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001576- SF bug #893549: parsing keyword arguments was broken with a few format
1577 codes.
1578
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001579- Changes donated by Elemental Security to make it work on AIX 5.3
1580 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1581 bug #105470: test_pwd fails on 64bit system (Opteron).
1582
Guido van Rossum539c6622005-09-14 17:49:54 +00001583- Changes donated by Elemental Security to make it work on HP-UX 11 on
1584 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1585
Georg Brandl4550b8d2005-08-26 06:43:52 +00001586- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001587 (fixes bug #1119418).
1588
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001589- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1590
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001591- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1592 exceptions that cause a function to exit.
1593
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001594- The implementation of set() and frozenset() was revised to use its
1595 own internal data structure. Memory consumption is reduced by 1/3
1596 and there are modest speed-ups as well. The API is unchanged.
1597
Tim Petersde7990b2005-07-17 23:45:23 +00001598- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1599
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001600- SF bug #1229429: PyObject_CallMethod failed to decrement some
1601 reference counts in some error exit cases.
1602
Tim Petersecc6e6a2005-07-10 22:30:55 +00001603- SF bug #1185883: Python's small-object memory allocator took over
1604 a block managed by the platform C library whenever a realloc specified
1605 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001606 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001607 portable way to copy data from the C-managed block into Python's
1608 small-object space without risking a memory fault. Python's small-object
1609 realloc now leaves such blocks under the control of the platform C
1610 realloc.
1611
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001612- SF bug #1232517: An overflow error was not detected properly when
1613 attempting to convert a large float to an int in os.utime().
1614
Raymond Hettinger3296e692005-06-29 23:29:56 +00001615- SF bug #1224347: hex longs now print with lowercase letters just
1616 like their int counterparts.
1617
Michael W. Hudson188d4362005-06-20 16:52:57 +00001618- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1619 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1620 interpreter states; back out that fix and do a better job (see
1621 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1622 for a longer write-up of the problem).
1623
Michael W. Hudsondf888462005-06-03 14:41:55 +00001624- SF patch #1180995: marshal now uses a binary format by default when
1625 serializing floats.
1626
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001627- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1628 the routines that promise to produce IEEE 754 binary representations
1629 of floats now simply copy bytes around.
1630
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001631- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1632 278.
1633
Brett Cannonc3647ac2005-04-26 03:45:26 +00001634- patch #1109424: int, long, float, complex, and unicode now check for the
1635 proper magic slot for type conversions when subclassed. Previously the
1636 magic slot was ignored during conversion. Semantics now match the way
1637 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001638 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001639 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001640 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001641
Barry Warsawc8d907c2005-04-19 23:43:40 +00001642- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1643 NULL, now raise an AttributeError when attempting to set or delete the
1644 attribute. Previously a TypeError was raised, but this was inconsistent
1645 with the equivalent pure-Python implementation.
1646
Michael W. Hudson774479c2005-04-18 08:46:17 +00001647- It is now safe to call PyGILState_Release() before
1648 PyEval_InitThreads() (note that if there is reason to believe there
1649 are multiple threads around you still must call PyEval_InitThreads()
1650 before using the Python API; this fix is for extension modules that
1651 have no way of knowing if Python is multi-threaded yet).
1652
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001653- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1654 disabled caused a crash.
1655
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001656- Bug #1165306: instancemethod_new allowed the creation of a method
1657 with im_class == im_self == NULL, which caused a crash when called.
1658
Tim Petersecc6e6a2005-07-10 22:30:55 +00001659- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001660 fixes the crash seen in bug #1165761
1661
Raymond Hettinger96229b12005-03-11 06:49:40 +00001662- Added two new builtins, any() and all().
1663
Brett Cannon409d8f22005-03-05 06:47:57 +00001664- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001665 (e.g., ``class C(): pass`` is no longer a syntax error).
1666 Patch #1176012 added support to the 'parser' module and 'compiler' package
1667 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001668
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001669- Patch #1115086: Support PY_LONGLONG in structmember.
1670
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001671- Bug #1155938: new style classes did not check that __init__() was
1672 returning None.
1673
Tim Petersecc6e6a2005-07-10 22:30:55 +00001674- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001675 ('\') with a specific error message.
1676
Martin v. Löwisff232d72005-03-03 09:24:38 +00001677- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1678
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001679- Bug #1124295: the __name__ attribute of file objects was
1680 inadvertently made inaccessible in restricted mode.
1681
Tim Petersecc6e6a2005-07-10 22:30:55 +00001682- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001683 an ferror() call.
1684
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001685- min() and max() now support key= arguments with the same meaning as in
1686 list.sort().
1687
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001688- The peephole optimizer now performs simple constant folding in expressions:
1689 (2+3) --> (5).
1690
Raymond Hettingera422c342005-01-11 03:03:27 +00001691- set and frozenset objects can now be marshalled. SF #1098985.
1692
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001693- Bug #1077106: Poor argument checking could cause memory corruption
1694 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001695
Jeremy Hyltonab630502005-02-04 18:44:06 +00001696- The parser did not complain about future statements in illegal
1697 positions. It once again reports a syntax error if a future
1698 statement occurs after anything other than a doc string.
1699
Neil Schemenauercf52c072005-08-12 17:34:58 +00001700- Change the %s format specifier for str objects so that it returns a
1701 unicode instance if the argument is not an instance of basestring and
1702 calling __str__ on the argument returns a unicode instance.
1703
Tim Petersf4e69282006-02-27 17:15:31 +00001704- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1705 current thread state when the auto-GIL-state machinery knows about
1706 it (since the thread state is being deleted, continuing to remember it
1707 can't help, but can hurt if another thread happens to get created with
1708 the same thread id).
1709
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001710Extension Modules
1711-----------------
1712
Georg Brandl43f08a82006-03-31 18:01:16 +00001713- Patch #1380952: fix SSL objects timing out on consecutive read()s

1716
Anthony Baxterfa869072006-03-20 05:21:58 +00001717- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1718 In addition, the existing ulaw code was updated.
1719
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001720- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00001721 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001722
Neal Norwitz10be10c2006-03-16 06:50:13 +00001723- Everything under lib-old was removed. This includes the following modules:
1724 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00001725 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001726 util, whatsound, whrandom, zmod
1727
1728- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1729
1730- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001731 is deprecated. The undocumented re.engine variable no longer exists.
1732
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001733- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1734 SS2 (single-shift 2) escape sequences correctly.
1735
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001736- The unicodedata module was updated to the 4.1 version of the Unicode
1737 database. The 3.2 version is still available as unicodedata.db_3_2_0
1738 for applications that require this specific version (such as IDNA).
1739
Neal Norwitzb62c4332006-03-04 18:35:47 +00001740- The timing module is no longer built by default. It was deprecated
1741 in PEP 4 in Python 2.0 or earlier.
1742
Guido van Rossum1968ad32006-02-25 22:38:04 +00001743- Patch 1433928: Added a new type, defaultdict, to the collections module.
1744 This uses the new __missing__ hook behavior added to dict (see above).
1745
Georg Brandldbd83392006-02-20 09:42:33 +00001746- Bug #854823: socketmodule now builds on Sun platforms even when
1747 INET_ADDRSTRLEN is not defined.
1748
Georg Brandlf4f44152006-02-18 22:29:33 +00001749- Patch #1393157: os.startfile() now has an optional argument to specify
1750 a "command verb" to invoke on the file.
1751
Neal Norwitz082b2df2006-02-07 07:04:46 +00001752- Bug #876637, prevent stack corruption when socket descriptor
1753 is larger than FD_SETSIZE.
1754
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00001755- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
1756 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1757 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
1758
Martin v. Löwis57a34e82006-02-04 19:12:37 +00001759- Patch #1422385: The nis module now supports access to domains other
1760 than the system default domain.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001900- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1901 been renamed to have only a single underscore prefix. This was done to
1902 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001903
Nick Coghlan43832302006-04-23 17:04:07 +00001904- PEP 338: new module runpy defines a run_module function to support
1905 executing modules which provide access to source code or a code object
1906 via the PEP 302 import mechanisms.
1907

1916 in attribute values.
1917
Anthony Baxterc51ee692006-04-01 00:57:31 +00001918- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001919 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001920 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001921 module will not be built.
1922
Tim Petersc17976e2006-04-01 00:26:53 +00001923- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1924 aren't officially supported here, and trying to use them will probably
1925 raise an exception some day. But dicts have been allowed, and "mostly
1926 worked", so support for them won't go away without warning.
1927
Georg Brandl338ef7d2006-03-31 18:42:16 +00001928- Bug #1445068: getpass.getpass() can now be given an explicit stream
1929 argument to specify where to write the prompt.

1946
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001947- email 4.0 package now integrated. This is largely the same as the email 3.0
1948 package that was included in Python 2.3, except that PEP 8 module names are
1949 now used (e.g. mail.message instead of email.Message). The MIME classes
1950 have been moved to a subpackage (e.g. email.mime.text instead of
1951 email.MIMEText). The old names are still supported for now. Several
1952 deprecated Message methods have been removed and lots of bugs have been
1953 fixed. More details can be found in the email package documentation.
1954
Walter Dörwald40108c92006-03-27 08:15:44 +00001955- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1956 (a subclass of tuple) that provides incremental decoders and encoders
1957 (a way to use stateful codecs without the stream API). Python functions
1958 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
1959 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
1960 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00001962- Patch #1359365: Calling next() on a closed StringIO.String object raises
1963 a ValueError instead of a StopIteration now (like file and cString.String do).
1964 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
1965 called before (like file and StringIO.StringIO do).

2033
Neal Norwitz338e7862005-12-23 21:27:46 +00002034- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
2035 LoadError as documented, instead of IOError. For compatibility,
2036 LoadError subclasses IOError.
2037
Brett Cannon3cbd0382005-12-16 22:49:23 +00002038- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00002039 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2040 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2041 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2042 Ronald L. Rivest offered this advice for Python:
2043
2044 "The consensus of researchers in this area (at least as
2045 expressed at the NIST Hash Function Workshop 10/31/05),
2046 is that SHA-256 is a good choice for the time being, but
2047 that research should continue, and other alternatives may
2048 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002049
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002050- Added a subset of Fredrik Lundh's ElementTree package. Available

2103 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002104 correct line numbers for decoding errors in source code.

2127 to W3C name (404 -> 'Not Found'). RFE #1216944.
2128
Georg Brandl9e43acf2005-07-04 17:16:07 +00002129- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2130 as this can cause problems with apps closing all file descriptors.

2143 Bug #1224621.
2144
Raymond Hettinger68c04532005-06-10 11:05:19 +00002145- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002146 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002147 the generate_tokens() function now accepts a callable argument that
2148 terminates by raising StopIteration.
2149
Georg Brandl9166e1a2005-06-04 09:20:03 +00002150- Bug #1196315: fix weakref.WeakValueDictionary constructor.

2154
Skip Montanaro174dd222005-05-14 20:54:16 +00002155- Patch #1120353: The xmlrpclib module provides better, more transparent,

2158 class at all.
2159
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002160- distutils.commands.upload was added to support uploading distribution

2164 them to PyPI.
2165
Raymond Hettinger267b8682005-03-27 10:47:39 +00002166- decimal operator and comparison methods now return NotImplemented
2167 instead of raising a TypeError when interacting with other types. This
2168 allows other classes to implement __radd__ style methods and have them
2169 work as expected.
2170
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002171- Bug #1163325: Decimal infinities failed to hash. Attempting to
2172 hash a NaN raised an InvalidOperation instead of a TypeError.
2173
Tim Petersecc6e6a2005-07-10 22:30:55 +00002174- Patch #918101: Add tarfile open mode r|* for auto-detection of the

2208
Guido van Rossumd0641422005-02-03 15:01:24 +00002209- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2210 disables recursive traversal through instance attributes, which can
2211 be exploited in various ways.
2212
Tim Peterse3547fd2005-12-16 23:13:57 +00002213- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002214 flags on the HTTP listening socket.
2215

Thomas Hellerd6c6e222005-01-20 19:20:16 +00002224- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2225
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002226- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2227
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002228- Enhancements to the csv module:
2229
2230 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002231 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002232 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002233 + Dialect parameter parsing has been re-implemented to improve error
2234 reporting.
2235 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2236 dictates.
2237 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002238 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002239 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002240 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2241 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002242 + reader now allows \r characters to be quoted (previously it only allowed
2243 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002244 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002245 + Dialect classes passed to the module are no longer instantiated by
2246 the module before being parsed (the former validation scheme required
2247 this, but the mechanism was unreliable).
2248 + The dialect registry now contains instances of the internal
2249 C-coded dialect type, rather than references to python objects.
2250 + the internal c-coded dialect type is now immutable.
2251 + register_dialect now accepts the same keyword dialect specifications
2252 as the reader and writer, allowing the user to register dialects
2253 without first creating a dialect class.
2254 + a configurable limit to the size of parsed fields has been added -
2255 previously, an unmatched quote character could result in the entire
2256 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002257 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002258 the parser field size limit (returning the former limit). The initial
2259 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002260 + A line_num attribute has been added to the reader object, which tracks
2261 the number of lines read from the source iterator. This is not
2262 the same as the number of records returned, as records can span
2263 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002264 + reader and writer objects were not being registered with the cyclic-GC.
2265 This has been fixed.
2266
Brett Cannone6539c42005-01-08 02:43:53 +00002267- _DummyThread objects in the threading module now delete self.__block that is
2268 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2269 lock primitives tend to be limited in number and thus should not be wasted on
2270 a _DummyThread object. Fixes bug #1089632.
2271
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002272- The imghdr module now detects Exif files.
2273
Raymond Hettinger6065d322004-12-20 23:51:53 +00002274- StringIO.truncate() now correctly adjusts the size attribute.
2275 (Bug #951915).
2276
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002277- locale.py now uses an updated locale alias table (built using
2278 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2279 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002280 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002281
Raymond Hettinger3557f422004-12-07 12:02:02 +00002282- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2283
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002284- the pickle module no longer accepts the deprecated None option in the
2285 args tuple returned by __reduce__().
2286
Brett Cannon84667c02004-12-07 03:25:18 +00002287- optparse now optionally imports gettext. This allows its use in setup.py.
2288
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002289- the pickle module no longer uses the deprecated bin parameter.
2290

2296
Raymond Hettinger664347b2004-12-04 21:21:53 +00002297- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2298 extended or overridden by subclasses. Formerly, the subclassed method would
2299 be ignored by the rest of the module. (Bug #1078905).
2300
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002301- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002302 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002303
Walter Dörwald36733692004-12-22 12:50:50 +00002304- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2305 once when a size argument is given. This prevents a buffer overflow in the
2306 tokenizer with very long source lines.
2307
Barry Warsaw538561e2006-01-01 21:48:54 +00002308- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2309 immediately after creating the object, without any intervening
2310 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002311
Skip Montanaro05885812005-01-16 20:48:27 +00002312- The reconvert.quote function can now emit triple-quoted strings. The
2313 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002314
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002315- ``UserString.MutableString`` now supports negative indices in
2316 ``__setitem__`` and ``__delitem__``
2317
Greg Ward40407942005-03-05 02:53:17 +00002318- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2319 correctly.
2320
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002321- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2322 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2323 character even if the user has passed a size parameter to get a proper
2324 line ending. Remove the special handling of a "\r\n" that has been split
2325 between two lines.
2326
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002327- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2328 about illegal code points. The codec now supports PEP 293 style error
2329 handlers.
2330
Walter Dörwald78a78b02005-09-01 12:04:29 +00002331- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002332 from the input stream, so that the output is a byte string in the correct
2333 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002334
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002335- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2336 considering it exactly like a '*'.
2337
Walter Dörwald007f8df2005-10-09 19:42:27 +00002338- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2339 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002340
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002341- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2342
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002343- Patch #1413711: Certain patterns of differences were making difflib
2344 touch the recursion limit.
2345
Walter Dörwald58917a62006-03-31 15:26:22 +00002346- Bug #947906: An object oriented interface has been added to the calendar
2347 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002348 called as a script (e.g. via ``python -mcalendar``). Localized month and
2349 weekday names can be ouput (even if an exotic encoding is used) using
2350 special classes that use unicode.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002352Build
2353-----
2354
Neal Norwitz602d3392006-03-31 08:21:40 +00002355- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2356 by using -mieee gcc option.
2357

2359
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002360- Build support for Win64-AMD64 was added.
2361
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002362- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2363
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002364- Patch #881820: look for openpty and forkpty also in libbsd.
2365
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002366- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2367 The zlib module is now builtin on Windows.
2368
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002369- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2370
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002371- Bug #1189330: configure did not correctly determine the necessary
2372 value of LINKCC if python was built with GCC 4.0.
2373
Trent Mick8321b422005-07-26 02:29:21 +00002374- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2375 vulnerability in zlib 1.2.1 and 1.2.2.
2376
Brett Cannon08cd5982005-04-24 22:26:38 +00002377- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2378 flags that change binary compatibility. Changes were also made to
2379 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002380 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002381
Bob Ippolitoed233462005-03-29 13:47:59 +00002382- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2383 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2384 no longer exists). This configure patch makes things right.
2385
Martin v. Löwise2713be2005-03-08 15:03:08 +00002386- Bug #1158607: Build with --disable-unicode again.
2387
Brett Cannon46d96232005-02-16 00:07:19 +00002388- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2389 defined. Discovered as a result of not being able to build on OS X.
2390
Brett Cannon516592f2004-12-07 00:42:59 +00002391- setup.py now uses the directories specified in LDFLAGS using the -L option
2392 and in CPPFLAGS using the -I option for adding library and include
2393 directories, respectively, for compiling extension modules against. This has
2394 led to the core being compiled using the values in CPPFLAGS. It also removes
2395 the need for the special-casing of both DarwinPorts and Fink for darwin since
2396 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2397 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2398 Fink, ``-I/opt/local/include`` for DarwinPorts).
2399
Brett Cannon43802422005-02-10 20:48:03 +00002400- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2401 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2402 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2403 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002405C API
2406-----
2407
Tim Petersc9d78aa2006-03-26 23:27:58 +00002408- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2409 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2410 is obtained via the ``PyObject_`` family, it must be released via the
2411 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2412 always been officially true, but when Python's small-object allocator was
2413 introduced, an attempt was made to cater to a few extension modules
2414 discovered at the time that obtained memory via ``PyObject_New`` but
2415 released it via ``PyMem_DEL``. It's years later, and if such code still
2416 exists it will fail now (probably with segfaults, but calling wrong
2417 low-level memory management functions can yield many symptoms).
2418
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002419- Added a C API for set and frozenset objects.
2420

2422
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002423- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2424 mapping argument now. This string is used as a mapping table. Byte values
2425 greater than the length of the string and 0xFFFE are treated as undefined
2426 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00002432- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002433
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002434- Patch #1276356: New resource "urlfetch" is implemented. This enables
2435 even impatient people to run tests that require remote files.
