407Core and builtins
408-----------------
409
Neal Norwitz24b6f202006-09-05 04:43:56 +0000410- Fix infinite recursion when subclassing long and overriding __hash__.
411
412- Fix concatenation (+=) of long strings.
413
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000414- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000415 compared equal or unequal to a string and a UnicodeDecodeError
416 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000417
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000418 Instead, the equal (==) and unequal (!=) comparison operators will
419 now issue a UnicodeWarning and interpret the two objects as
420 unequal. The UnicodeWarning can be filtered as desired using
421 the warning framework, e.g. silenced completely, turned into an
422 exception, logged, etc.
423
424 Note that compare operators other than equal and unequal will still
425 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000426
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000427- Fix segfault when doing string formatting on subclasses of long.
428
429- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
430 with new-style classes.
431
432- Fix bug related to __len__ functions returning negative values with
433 classic classes.
434
435- Patch #1538606, Fix __index__() clipping. There were some problems
436 discovered with the API and how integers that didn't fit into Py_ssize_t
437 were handled. This patch attempts to provide enough alternatives
438 to effectively use __index__.
439
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000440- Bug #1536021: __hash__ may now return long int; the final hash
441 value is obtained by invoking hash on the long int.
442
Thomas Hellerab1049c2006-08-08 17:37:00 +0000443- Bug #1536786: buffer comparison could emit a RuntimeWarning.
444
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000445- Bug #1535165: fixed a segfault in input() and raw_input() when
446 sys.stdin is closed.
447
Thomas Heller74d36f02006-08-04 18:17:40 +0000448- On Windows, the PyErr_Warn function is now exported from
449 the Python dll again.
450
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000451- Bug #1191458: tracing over for loops now produces a line event
452 on each iteration. Fixing this problem required changing the .pyc
453 magic number. This means that .pyc files generated before 2.5c1
454 will be regenerated.
455
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000456- Bug #1333982: string/number constants were inappropriately stored
457 in the byte code and co_consts even if they were not used, ie
458 immediately popped off the stack.
459
Georg Brandle9462c72006-08-04 18:03:37 +0000460- Fixed a reference-counting problem in property().

463Library
464-------
465
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000466- Fix a bug in the ``compiler`` package that caused invalid code to be
467 generated for generator expressions.
468
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000469- The distutils version has been changed to 2.5.0. The change to
470 keep it programmatically in sync with the Python version running
471 the code (introduced in 2.5b3) has been reverted. It will continue
472 to be maintained manually as static string literal.
473
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000474- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000475 and this cannot be converted to the required C type, an exception is
476 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000477 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000478
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000479- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000480 an exception.
481
Tim Peterscbdd3502006-09-05 01:47:53 +0000482- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000483 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000484 workarounds for clocks with low resolution, to stop the code yielding
485 duplicate UUIDs.
486
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000487- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
488 before raising SystemExit, allowing IDLE to honor quit() and exit().
489
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000490- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
491
Georg Brandl7a1af772006-08-14 21:55:28 +0000492- Patch #1536071: trace.py should now find the full module name of a
493 file correctly even on Windows.
494
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000495- logging's atexit hook now runs even if the rest of the module has
496 already been cleaned up.
497
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000498- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000499
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000500- Bug #1531405, format_exception no longer raises an exception if
501 str(exception) raised an exception.
502
Neil Schemenauer06ded092006-08-04 16:20:30 +0000503- Fix a bug in the ``compiler`` package that caused invalid code to be
504 generated for nested functions.

515 raises the correct exceptions.
516
Thomas Heller1ce433e2006-08-14 16:20:04 +0000517- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
518 '-no-stack-protector' compiler flag for OpenBSD has been removed.
519
Thomas Heller86720042006-08-14 11:17:48 +0000520- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
521 uses the _as_parameter_ attribute when objects are passed to foreign
522 function calls. The ctypes version number was changed to 1.0.1.
523
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000524- Bug #1530559, struct.pack raises TypeError where it used to convert.
525 Passing float arguments to struct.pack when integers are expected
526 now triggers a DeprecationWarning.
527
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000528

576Core and builtins
577-----------------
578
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000579- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000580 returned a long (see PEP 353).
581
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000582- Bug #1515471: string.replace() accepts character buffers again.
583
Neal Norwitz07aadb12006-07-30 06:55:48 +0000584- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
585 This provides the proper warning for struct.pack().
586 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
587
Neal Norwitz0d62a062006-07-30 06:53:31 +0000588- Patch #1531113: Fix augmented assignment with yield expressions.
589 Also fix a SystemError when trying to assign to yield expressions.
590
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000591- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
592 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
593 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
594 excessive filesystem operations during imports.
595
Tim Petersbc24eee2006-07-27 01:14:53 +0000596- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
597 operations on signed longs that are formally undefined by C.
598 Unfortunately, at least one compiler now cares about that, so complicated
599 the code to make that compiler happy again.
600
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000601- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
602
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000603- Patch #1232023: Stop including current directory in search
604 path on Windows.
605
Neal Norwitze1fdb322006-07-21 05:32:28 +0000606- Fix some potential crashes found with failmalloc.
607
Neal Norwitze7563102006-07-17 01:00:16 +0000608- Fix warnings reported by Klocwork's static analysis tool.
609
Neal Norwitz84be93b2006-07-16 01:50:38 +0000610- Bug #1512814, Fix incorrect lineno's when code within a function
611 had more than 255 blank lines.
612
Georg Brandl9dceedb2006-07-12 15:31:17 +0000613- Patch #1521179: Python now accepts the standard options ``--help`` and
614 ``--version`` as well as ``/?`` on Windows.
615
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000616- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000617 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000618 This means that .pyc files generated before 2.5b3 will be regenerated.

Tim Peters112aad32006-07-19 00:03:19 +0000620- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000621 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000622 new ``sys._current_frames()`` returns a dictionary with one entry,
623 mapping the faux "thread id" 0 to the current frame.

629-------
630
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000631- Correction of patch #1455898: In the mbcs decoder, set final=False
632 for stream decoder, but final=True for the decode function.
633
Georg Brandl07fec3a2006-08-01 18:49:24 +0000634- os.urandom no longer masks unrelated exceptions like SystemExit or
635 KeyboardInterrupt.
636
Tim Peters4643c2f2006-08-10 22:45:34 +0000637- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000638 shutil.copytree on Windows
639
Georg Brandle34ac7c2006-07-30 11:07:23 +0000640- Bug #1002398: The documentation for os.path.sameopenfile now correctly
641 refers to file descriptors, not file objects.
642
Tim Peterscbdd3502006-09-05 01:47:53 +0000643- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000644 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000645 #1513611, and probably others.
646
Georg Brandledd9b0d2006-07-29 09:33:26 +0000647- Bug #1441397: The compiler module now recognizes module and function
648 docstrings correctly as it did in Python 2.4.
649
Tim Peters6f681472006-07-27 23:44:37 +0000650- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
651 lost that tests are sorted by name before being run. This rarely
652 matters for well-written tests, but can create baffling symptoms if
653 side effects from one test to the next affect outcomes. ``DocTestFinder``
654 has been changed to sort the list of tests it returns.
655
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000656- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000657 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000658
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000659- Bug #978833: Really close underlying socket in _socketobject.close.
660
Georg Brandldb232dc2006-08-20 13:15:43 +0000661- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
662 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000663
Georg Brandlcf0c1722006-07-26 07:23:32 +0000664- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
665 to recursive calls and call it with the failing package name.
666
Martin v. Löwis0b483032006-07-25 09:53:12 +0000667- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
668
Georg Brandlc13c34c2006-07-24 14:09:56 +0000669- Patch #1515343: Fix printing of deprecated string exceptions with a
670 value in the traceback module.
671
Greg Ward48fae7a2006-07-23 16:05:51 +0000672- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
673
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000674- Patch #1524429: Use repr() instead of backticks in Tkinter again.
675
Brett Cannoncaebe222006-07-18 04:41:36 +0000676- Bug #1520914: Change time.strftime() to accept a zero for any position in its
677 argument tuple. For arguments where zero is illegal, the value is forced to
678 the minimum value that is correct. This is to support an undocumented but
679 common way people used to fill in inconsequential information in the time
680 tuple pre-2.4.
681
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000682- Patch #1220874: Update the binhex module for Mach-O.
683
Barry Warsawb110bad2006-07-21 14:51:07 +0000684- The email package has improved RFC 2231 support, specifically for
685 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
686 (name*0=<blah>) parameter continuations. This may change the types of
687 values returned from email.message.Message.get_param() and friends.
688 Specifically in some cases where non-encoded continuations were used,
689 get_param() used to return a 3-tuple of (None, None, string) whereas now it
690 will just return the string (since non-encoded continuations don't have
691 charset and language parts).
692
693 Also, whereas % values were decoded in all parameter continuations, they are
694 now only decoded in encoded parameter parts.
695
Ronald Oussoren3075e162006-07-25 20:28:55 +0000696- Bug #1517990: IDLE keybindings on MacOS X now work correctly
697
698- Bug #1517996: IDLE now longer shows the default Tk menu when a
699 path browser, class browser or debugger is the frontmost window on MacOS X
700
Barry Warsaw00decd72006-07-27 23:43:15 +0000701- Patch #1520294: Support for getset and member descriptors in types.py,
702 inspect.py, and pydoc.py. Specifically, this allows for querying the type
703 of an object against these built-in types and more importantly, for getting
704 their docstrings printed in the interactive interpreter's help() function.

708-----------------
709
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000710- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
711 a socket operation on a socket with a timeout, the exception will be
712 caught correctly. Previously, the exception was not caught.
713
Thomas Heller1393d6a2006-07-28 21:43:20 +0000714- Patch #1529514: The _ctypes extension is now compiled on more
715 openbsd target platforms.
716
Tim Peters9cab5932006-07-28 00:30:00 +0000717- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
718 a memory leak, affecting pickles and deep copies.
719
Tim Petersbc24eee2006-07-27 01:14:53 +0000720- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

722
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000723- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
724
Thomas Hellerce049a02006-07-14 17:51:14 +0000725- Patch #1521817: Index range checking on ctypes arrays containing
726 exactly one element enabled again. This allows iterating over these
727 arrays, without the need to check the array size before.
728
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000729- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000730 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000731 /dev/null in certain cases; this is now fixed.
732
Thomas Heller47d7a062006-07-12 08:43:47 +0000733- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
734 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000735
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000736- Because of a misspelled preprocessor symbol, ctypes was always
737 compiled without thread support; this is now fixed.
738
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000739- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
740 methods now allow their database parameter to be None as the
741 sleepycat API allows.
742
Matt Flemingec926502006-07-28 11:27:27 +0000743- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
744 bluetooth API compared with Linux and FreeBSD.
745
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000746Tests
747-----
748
749- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
750 how long the test file should take to play. Now accepts taking 2.93 secs
751 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
752
Georg Brandl4793aa32006-07-28 18:31:39 +0000753- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
754 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
755 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +0000762Mac
763---
764
765- PythonLauncher now works correctly when the path to the script contains
766 characters that are treated specially by the shell (such as quotes).
767
768- Bug #1527397: PythonLauncher now launches scripts with the working directory
769 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000770 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000771 expect.

780-----------------
781
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000782- Bug #1441486: The literal representation of -(sys.maxint - 1)
783 again evaluates to a int object, not a long.
784
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000785- Bug #1501934: The scope of global variables that are locally assigned
786 using augmented assignment is now correctly determined.
787
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000788- Bug #927248: Recursive method-wrapper objects can now safely
789 be released.
790
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000791- Bug #1417699: Reject locale-specific decimal point in float()
792 and atof().
793
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000794- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
795 omit a default "error" argument for NULL pointer. This allows
796 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000797
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000798- Bug #1519018: 'as' is now validated properly in import statements.
799
Neal Norwitz28746ab2006-07-09 22:14:42 +0000800- On 64 bit systems, int literals that use less than 64 bits are
801 now ints rather than longs.
802
Neal Norwitzed657552006-07-10 00:04:44 +0000803- Bug #1512814, Fix incorrect lineno's when code at module scope
804 started after line 256.
805
Tim Peters32a83612006-07-10 21:08:24 +0000806- New function ``sys._current_frames()`` returns a dict mapping thread
807 id to topmost thread stack frame. This is for expert use, and is
808 especially useful for debugging application deadlocks. The functionality
809 was previously available in Fazal Majid's ``threadframe`` extension
810 module, but it wasn't possible to do this in a wholly threadsafe way from
811 an extension.

820
Tim Peters32a83612006-07-10 21:08:24 +0000821- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000822 environment variable to be set in order to the SDK environment
823 for finding the compiler, include files, etc.

828
Thomas Woutersadd19112006-07-05 11:03:49 +0000829- string.Template() now correctly handles tuple-values. Previously,
830 multi-value tuples would raise an exception and single-value tuples would
831 be treated as the value they contain, instead.
832
Martin v. Löwisede77f52006-07-03 13:01:35 +0000833- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

841
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000842- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +0000843 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +0000844

846 is created.
847

852 attribute values.
853
854- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
855 sgmllib ('[' and ']' were not accepted).
856
Georg Brandl1be63af2006-06-28 20:23:25 +0000857- Fix a bug in the turtle module's end_fill function.
858
Brett Cannon53ab5b72006-06-22 16:49:14 +0000859- Bug #1510580: The 'warnings' module improperly required that a Warning
860 category be either a types.ClassType and a subclass of Warning. The proper
861 check is just that it is a subclass with Warning as the documentation states.
862
Georg Brandlad29e632006-06-21 17:45:17 +0000863- The compiler module now correctly compiles the new try-except-finally
864 statement (bug #1509132).
865
Neal Norwitz60373cd2006-06-22 06:30:50 +0000866- The wsgiref package is now installed properly on Unix.
867
Vinay Sajip28e57612006-07-01 10:45:20 +0000868- A bug was fixed in logging.config.fileConfig() which caused a crash on
869 shutdown when fileConfig() was called multiple times.
870
Gerhard Häring762fbd32006-07-02 17:48:30 +0000871- The sqlite3 module did cut off data from the SQLite database at the first
872 null character before sending it to a custom converter. This has been fixed
873 now.

877
Tim Peters112aad32006-07-19 00:03:19 +0000878- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
879 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
880 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000881
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000882- Assigning None to pointer type fields in ctypes structures possible
883 overwrote the wrong fields, this is fixed now.
884
885- Fixed a segfault in _ctypes when ctypes.wintypes were imported
886 on non-Windows platforms.
887
888- Bug #1518190: The ctypes.c_void_p constructor now accepts any
889 integer or long, without range checking.
890
891- Patch #1517790: It is now possible to use custom objects in the ctypes
892 foreign function argtypes sequence as long as they provide a from_param
893 method, no longer is it required that the object is a ctypes type.
894
895- The '_ctypes' extension module now works when Python is configured
896 with the --without-threads option.
897
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000898- Bug #1513646: os.access on Windows now correctly determines write
899 access, again.

913
Tim Peters32a83612006-07-10 21:08:24 +0000914- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000915 Previously, the slight difference could cause compilation errors of the
916 'zlib' module on systems with more than one version of zlib.

949Core and builtins
950-----------------
951
Georg Brandla56b9152006-06-19 06:35:54 +0000952- Patch #1507676: Error messages returned by invalid abstract object operations
953 (such as iterating over an integer) have been improved and now include the
954 type of the offending object to help with debugging.
955
Brett Cannonea3912b2006-06-13 21:46:41 +0000956- Bug #992017: A classic class that defined a __coerce__() method that returned
957 its arguments swapped would infinitely recurse and segfault the interpreter.
958
Neal Norwitz909eb122006-06-12 02:13:21 +0000959- Fix the socket tests so they can be run concurrently.
960
Neal Norwitzb9845e72006-06-12 02:11:18 +0000961- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +0000962 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +0000963
Brett Cannon22565aa2006-06-09 22:31:23 +0000964- Bug #532646: object.__call__() will continue looking for the __call__
965 attribute on objects until one without one is found. This leads to recursion
966 when you take a class and set its __call__ attribute to an instance of the
967 class. Originally fixed for classic classes, but this fix is for new-style.
968 Removes the infinite_rec_3 crasher.
969
Georg Brandl24250812006-06-09 18:45:48 +0000970- The string and unicode methods startswith() and endswith() now accept
971 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
972
Brett Cannonde3b0522006-06-08 17:00:45 +0000973- Buffer objects, at the C level, never used the char buffer
974 implementation even when the char buffer for the wrapped object was
975 explicitly requested (originally returned the read or write buffer).
976 Now a TypeError is raised if the char buffer is not present but is
977 requested.
978
Georg Brandlddbaa662006-06-04 21:56:52 +0000979- Patch #1346214: Statements like "if 0: suite" are now again optimized
980 away like they were in Python 2.4.
981
Georg Brandlb7c8f542006-05-27 12:30:25 +0000982- Builtin exceptions are now full-blown new-style classes instead of
983 instances pretending to be classes, which speeds up exception handling
984 by about 80% in comparison to 2.5a2.
985
Martin v. Löwisd004fc82006-05-27 08:36:52 +0000986- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
987 Unicode 4.1.
988
Georg Brandlf4ef1162006-05-26 18:03:31 +0000989- Patch #921466: sys.path_importer_cache is now used to cache valid and
990 invalid file paths for the built-in import machinery which leads to
991 fewer open calls on startup.
992
Tim Peters696cf432006-05-24 21:10:40 +0000993- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
994 of-2 bases. The largest speedup is for inputs with about 1000 decimal
995 digits. Conversion from non-power-of-2 bases remains quadratic-time in
996 the number of input digits (it was and remains linear-time for bases
997 2, 4, 8, 16 and 32).
998
Tim Petersb713ec22006-05-23 18:45:30 +0000999- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1000 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1001 an integer close to ``sys.maxint``. This was repaired by patch
1002 #1335972, which also gives a nice speedup.
1003
Richard Jonescebbefc2006-05-23 18:28:17 +00001004- Patch #1337051: reduced size of frame objects.
1005
1006- PyErr_NewException now accepts a tuple of base classes as its
1007 "base" parameter.
1008
Richard Jones7c88dcc2006-05-23 10:37:38 +00001009- Patch #876206: function call speedup by retaining allocated frame
1010 objects.
1011
Georg Brandl7b90e162006-05-18 07:01:27 +00001012- Bug #1462152: file() now checks more thoroughly for invalid mode
1013 strings and removes a possible "U" before passing the mode to the
1014 C library function.
1015
Neal Norwitz1004a532006-05-15 07:17:23 +00001016- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1017
Neal Norwitz373f0a72006-05-15 07:04:36 +00001018- Bug #1487966: Fix SystemError with conditional expression in assignment
1019
Martin v. Löwis879768d2006-05-11 13:28:43 +00001020- WindowsError now has two error code attributes: errno, which carries
1021 the error values from errno.h, and winerror, which carries the error
1022 values from winerror.h. Previous versions put the winerror.h values
1023 (from GetLastError()) into the errno attribute.
1024
Martin v. Löwis77736712006-05-04 05:51:03 +00001025- Patch #1475845: Raise IndentationError for unexpected indent.
1026
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001027- Patch #1479181: split open() and file() from being aliases for each other.
1028
Tim Peters44bd9862006-06-01 13:49:23 +00001029- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1030 methods were always silently ignored by dictionaries when comparing keys.
1031 They are now passed through (except when using the C API function
1032 ``PyDict_GetItem()``, whose semantics did not change).
1033
1034- Bug #1456209: In some obscure cases it was possible for a class with a
1035 custom ``__eq__()`` method to confuse dict internals when class instances
1036 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1037 No, you don't have any code that did this ;-)

1041
Trent Mick960a3f82006-06-28 20:30:41 +00001042- Bug #1295808: expat symbols should be namespaced in pyexpat
1043
1044- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1045
Brett Cannon6ee7d012006-06-08 16:23:04 +00001046- Change binascii.hexlify to accept a read-only buffer instead of only a char
1047 buffer and actually follow its documentation.
1048
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001049- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1050
Nick Coghlanc649ec52006-05-29 12:43:05 +00001051- Patch #1478788 (modified version): The functional extension module has
1052 been renamed to _functools and a functools Python wrapper module added.
1053 This provides a home for additional function related utilities that are
1054 not specifically about functional programming. See PEP 309.
1055
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001056- Patch #1493701: performance enhancements for struct module.
1057
Georg Brandl378d5922006-05-17 14:26:50 +00001058- Patch #1490224: time.altzone is now set correctly on Cygwin.
1059
Georg Brandl8d3342b2006-05-16 07:38:27 +00001060- Patch #1435422: zlib's compress and decompress objects now have a
1061 copy() method.
1062
Andrew MacIntyre92913322006-06-13 15:04:24 +00001063- Patch #1454481: thread stack size is now tunable at runtime for thread
1064 enabled builds on Windows and systems with Posix threads support.
1065
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001066- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1067 (up to the system limit of 32K characters).
1068
1069- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1070 As a result, these functions now raise WindowsError instead of OSError.
1071
Tim Peters7a822da2006-05-25 21:50:17 +00001072- ``time.clock()`` on Win64 should use the high-performance Windows
1073 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1074 Windows platforms).
1075
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001076- Calling Tk_Init twice is refused if the first call failed as that
1077 may deadlock.
1078
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001079- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1080 accept it without potentially using an uninitialized pointer.
1081
1082- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1083 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1084 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001085
Gregory P. Smith372b5832006-06-05 18:48:21 +00001086- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001087 [pybsddb project SF patch number 1466734]
1088
Gregory P. Smith372b5832006-06-05 18:48:21 +00001089- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1090 parameter is supplied. [SF pybsddb bug #1477863]
1091
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001092- bsddb: the __len__ method of a DB object has been fixed to return correct
1093 results. It could previously incorrectly return 0 in some cases.
1094 Fixes SF bug 1493322 (pybsddb bug 1184012).
1095
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001096- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1097 aborts the db transaction safely when a modifier callback fails.
1098 Fixes SF python patch/bug #1408584.
1099
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001100- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001101 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001102 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1103 database calls that would previously deadlock. [SF python bug #775414]
1104
Vinay Sajip28e57612006-07-01 10:45:20 +00001105- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001106
Walter Dörwald4994d952006-06-19 08:07:50 +00001107- Patch #1506645: add Python wrappers for the curses functions
1108 is_term_resized, resize_term and resizeterm.

1111-------
1112
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001113- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1114 functions.
1115
Martin v. Löwis3798da02006-06-17 18:44:27 +00001116- Patch #812986: Update turtle output even if not tracing.
1117
Vinay Sajip28e57612006-07-01 10:45:20 +00001118- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001119 Tkinter.BaseWidget.
1120
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001121- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1122
Martin v. Löwis337487e2006-06-17 09:15:14 +00001123- Patch #763580: Add name and value arguments to Tkinter variable
1124 classes.
1125
Georg Brandl83cc0d02006-06-14 08:50:03 +00001126- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1127 mime.types file for determining MIME types.
1128
Georg Brandl2605ca82006-06-14 06:08:31 +00001129- Bug #1339007: Shelf objects now don't raise an exception in their
1130 __del__ method when initialization failed.
1131
Martin v. Löwisd8251432006-06-14 05:21:04 +00001132- Patch #1455898: The MBCS codec now supports the incremental mode for
1133 double-byte encodings.
1134
Tim Peters43898b42006-06-14 04:09:25 +00001135- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1136 guarantee that adjacent triples in the return list always describe
1137 non-adjacent blocks. Previously, a pair of matching blocks could end
1138 up being described by multiple adjacent triples that formed a partition
1139 of the matching pair.
1140
Greg Ward0e0c9f42006-06-11 16:24:11 +00001141- Bug #1498146: fix optparse to handle Unicode strings in option help,
1142 description, and epilog.
1143
Greg Wardd1c797e2006-06-11 14:42:41 +00001144- Bug #1366250: minor optparse documentation error.
1145
Greg Ward7f547402006-06-11 00:40:49 +00001146- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1147 clarify docs.
1148
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001149- The wsgiref package has been added to the standard library.
1150
Nick Coghlan676725d2006-06-08 13:54:49 +00001151- The functions update_wrapper() and wraps() have been added to the functools
1152 module. These make it easier to copy relevant metadata from the original
1153 function when writing wrapper functions.
1154
Tim Petersd6a9eef2006-06-05 01:48:21 +00001155- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1156 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001157
Martin v. Löwis3f767792006-06-04 19:36:28 +00001158- Patch #1359618: Speed up charmap encoder by using a trie structure
1159 for lookup.
1160
Tim Petersd609b1a2006-06-02 23:22:51 +00001161- The functions in the ``pprint`` module now sort dictionaries by key
1162 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1163 if and only if its display required more than one line, although that
1164 wasn't documented. The new behavior increases predictability; e.g.,
1165 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1166
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001167- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1168 (thanks for J. J. Lee).
1169
Georg Brandl2b330372006-05-28 20:23:12 +00001170- Patch #1496206: improve urllib2 handling of passwords with respect to
1171 default HTTP and HTTPS ports.
1172
George Yoshidaf3c65de2006-05-28 16:39:09 +00001173- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1174
Bob Ippolito7298f272006-05-23 18:43:47 +00001175- Patch #1281707: speed up gzip.readline.
1176
Georg Brandlb89316f2006-05-17 15:51:16 +00001177- Patch #1180296: Two new functions were added to the locale module:
1178 format_string() to get the effect of "format % items" but locale-aware,
1179 and currency() to format a monetary number with currency sign.
1180
Georg Brandle3a25832006-05-17 14:56:04 +00001181- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1182 and several features added, such as speed and geometry control.
1183
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001184- Patch #1488881: add support for external file objects in bz2 compressed
1185 tarfiles.
1186
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001187- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1188 stdout arguments, making it possible to redirect input and output
1189 for remote debugging.
1190
1191- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1192 a couple of issues, notably handling of long file names using the
1193 GNU LONGNAME extension.
1194
1195- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1196 new flag when ``name`` is already the name of an option flag.
1197
1198- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1199 package.
1200
1201- Patch #1472854: make the rlcompleter.Completer class usable on non-
1202 UNIX platforms.
1203
1204- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1205
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001206- Bug #1472827: correctly escape newlines and tabs in attribute values in
1207 the saxutils.XMLGenerator class.

Georg Brandl66a0dbb2006-06-08 12:54:13 +00001213- Bug #1502728: Correctly link against librt library on HP-UX.
1214
Martin v. Löwis222c5152006-06-03 07:37:13 +00001215- OpenBSD 3.9 is supported now.
1216

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001237What's New in Python 2.5 alpha 2?
1238=================================
1239
1240*Release date: 27-APR-2006*
1241
1242Core and builtins
1243-----------------
1244
Thomas Heller1b046642006-04-18 18:51:06 +00001245- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1246 by converting these apis from macros into exported functions again:
1247
1248 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1249 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1250 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1251 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1252 PyRun_String Py_CompileString
1253
Martin v. Löwis45294a92006-04-18 06:24:08 +00001254- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1255
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001256- All uses of PyStructSequence_InitType have been changed to initialize
1257 the type objects only once, even if the interpreter is initialized
1258 multiple times.
1259
Neal Norwitz61546162006-04-14 05:20:28 +00001260- Bug #1454485, array.array('u') could crash the interpreter. This was
1261 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1262 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1263
1264- Py_UNICODE is unsigned. It was always documented as unsigned, but
1265 due to a bug had a signed value in previous versions.
1266
Tim Peters3a5e8b12006-04-11 01:44:07 +00001267- Patch #837242: ``id()`` of any Python object always gives a positive
1268 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1269 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001270 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001271 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001272
Tim Peters3a5e8b12006-04-11 01:44:07 +00001273 def __hash__(self):
1274 return id(self) # WRONG
1275
1276 because a hash result must be a (short) Python int but it was always
1277 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001278 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001279 was always usable as a hash value before this patch. That's no longer
1280 necessarily so.
1281
1282- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001283 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001284 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001285 #1454844)
1286
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001287- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1288 involving generators that have paused outside of any ``try`` or ``with``
1289 blocks. (In 2.5a1, a paused generator that was part of a reference
1290 cycle could not be garbage collected, regardless of whether it was
1291 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001292
Anthony Baxter51bcb682006-04-05 14:51:42 +00001293Extension Modules
1294-----------------
1295
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001296- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1297 is a macro.
1298
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001299- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1300 fails with an error condition.
1301
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001302- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1303
1304- Bug #1117761: bsddb.*open() no longer raises an exception when using
1305 the cachesize parameter.
1306
1307- Bug #1149413: bsddb.*open() no longer raises an exception when using
1308 a temporary db (file=None) with the 'n' flag to truncate on open.
1309
1310- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1311 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001312
Armin Rigoa9017c32006-04-19 11:50:27 +00001313- Patch #1062014: AF_UNIX sockets under Linux have a special
1314 abstract namespace that is now fully supported.
1315
Anthony Baxter51bcb682006-04-05 14:51:42 +00001316Library
1317-------
1318
Peter Astrand7d1d4362006-07-14 14:04:45 +00001319- Bug #1223937: subprocess.CalledProcessError reports the exit status
1320 of the process using the returncode attribute, instead of
1321 abusing errno.
1322
Tim Peters711bf302006-04-25 03:31:36 +00001323- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1324 a doctest to be skipped (the code is not run, and the expected output
1325 or exception is ignored).
1326
Nick Coghlanda2268f2006-04-24 04:37:15 +00001327- Fixed contextlib.nested to cope with exceptions being raised and
1328 caught inside exit handlers.
1329
Greg Wardab05edc2006-04-23 03:47:58 +00001330- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1331 hex, octal, or binary; add ``append_const`` action; keep going if
1332 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1333 added ``epilog`` for better help generation).
1334
Tim Peters21fbd572006-04-21 21:18:10 +00001335- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1336 called from a thread spawned as a side effect of importing a module.
1337
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001338- The pydoc module now supports documenting packages contained in
1339 .zip or .egg files.
1340
1341- The pkgutil module now has several new utility functions, such
1342 as ``walk_packages()`` to support working with packages that are either
1343 in the filesystem or zip files.
1344
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001345- The mailbox module can now modify and delete messages from
1346 mailboxes, in addition to simply reading them. Thanks to Gregory
1347 K. Johnson for writing the code, and to the 2005 Google Summer of
1348 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001349
Tim Petersc7605f22006-04-17 21:12:33 +00001350- The ``__del__`` method of class ``local`` in module ``_threading_local``
1351 returned before accomplishing any of its intended cleanup.
1352
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001353- Patch #790710: Add breakpoint command lists in pdb.
1354
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001355- Patch #1063914: Add Tkinter.Misc.clipboard_get().
1356
Martin v. Löwis4b501e62006-04-15 08:41:11 +00001357- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1358
Anthony Baxtere29002c2006-04-12 12:07:31 +00001359- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1360 Windows. Bug #1469163.
1361
Phillip J. Eby47032112006-04-11 01:07:43 +00001362- The warnings, linecache, inspect, traceback, site, and doctest modules
1363 were updated to work correctly with modules imported from zipfiles or
1364 via other PEP 302 __loader__ objects.
1365
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001366- Patch #1467770: Reduce usage of subprocess._active to processes which
1367 the application hasn't waited on.
1368
Martin v. Löwisb04dee92006-04-10 08:34:21 +00001369- Patch #1462222: Fix Tix.Grid.
1370
Neal Norwitza31bf182006-04-09 03:35:43 +00001371- Fix exception when doing glob.glob('anything*/')
1372
Skip Montanaro262fb922006-04-21 02:31:07 +00001373- The pstats.Stats class accepts an optional stream keyword argument to
1374 direct output to an alternate file-like object.
1375
Anthony Baxter51bcb682006-04-05 14:51:42 +00001376Build
1377-----
1378
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001379- The Makefile now has a reindent target, which runs reindent.py on
1380 the library.
1381
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001382- Patch #1470875: Building Python with MS Free Compiler
1383
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001384- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001385
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001386- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1387 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001388 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001389 CXX from --with-cxx-main, see description in README.
1390
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001391- Patch #1429775: Link extension modules with the shared libpython.
1392
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001393- Fixed a libffi build problem on MIPS systems.
1394
Tim Peters8931ff12006-05-13 23:28:20 +00001395- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1396 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1397 and "%zu" for unsigned integers of type ``size_t``.
1398
Anthony Baxter51bcb682006-04-05 14:51:42 +00001399Tests
1400-----
1401
Nick Coghlanda2268f2006-04-24 04:37:15 +00001402- test_contextlib now checks contextlib.nested can cope with exceptions
1403 being raised and caught inside exit handlers.
1404
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001405- test_cmd_line now checks operation of the -m and -c command switches
1406
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001407- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1408 it separately and by hand. It also wasn't cleaning up its changes to
1409 the current Decimal context.
1410
Thomas Woutersabd08882006-04-26 15:53:30 +00001411- regrtest.py now has a -M option to run tests that test the new limits of
1412 containers, on 64-bit architectures. Running these tests is only sensible
1413 on 64-bit machines with more than two gigabytes of memory. The argument
1414 passed is the maximum amount of memory for the tests to use.
1415
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001416Tools
1417-----
1418
1419- Added the Python benchmark suite pybench to the Tools/ directory;
1420 contributed by Marc-Andre Lemburg.
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001421
Anthony Baxter51bcb682006-04-05 14:51:42 +00001422Documentation
1423-------------
1424
Tim Petersb06d28c2006-05-12 01:57:59 +00001425- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1426
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001427- PEP 343: Added Context Types section to the library reference
1428 and attempted to bring other PEP 343 related documentation into
1429 line with the implementation and/or python-dev discussions.
1430
Tim Peters8dc73d22006-04-24 02:03:16 +00001431- Bug #1337990: clarified that ``doctest`` does not support examples
1432 requiring both expected output and an exception.
Anthony Baxter51bcb682006-04-05 14:51:42 +00001433
1434
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001435What's New in Python 2.5 alpha 1?
1436=================================
1437
Anthony Baxterebed3f62006-04-03 15:03:44 +00001438*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001439
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001440Core and builtins
1441-----------------
1442
Nick Coghlan43832302006-04-23 17:04:07 +00001443- PEP 338: -m command line switch now delegates to runpy.run_module
1444 allowing it to support modules in packages and zipfiles
1445
Martin v. Löwisc661b882006-04-20 04:54:23 +00001446- On Windows, .DLL is not an accepted file name extension for
1447 extension modules anymore; extensions are only found if they
1448 end in .PYD.
1449
Martin v. Löwisea62d252006-04-03 10:56:49 +00001450- Bug #1421664: sys.stderr.encoding is now set to the same value as
1451 sys.stdout.encoding.
1452
Neal Norwitz92e212f2006-04-03 04:48:37 +00001453- __import__ accepts keyword arguments.
1454
Georg Brandlccadf842006-03-31 18:54:53 +00001455- Patch #1460496: round() now accepts keyword arguments.
1456
Anthony Baxter262c00a2006-03-30 10:53:17 +00001457- Fixed bug #1459029 - unicode reprs were double-escaped.
1458
Hye-Shik Changd478f342006-03-23 12:32:36 +00001459- Patch #1396919: The system scope threads are reenabled on FreeBSD
1460 5.4 and later versions.
1461
Neal Norwitze98ccf62006-03-23 05:39:47 +00001462- Bug #1115379: Compiling a Unicode string with an encoding declaration
1463 now gives a SyntaxError.
1464
Georg Brandlabd1ff82006-03-18 07:59:59 +00001465- Previously, Python code had no easy way to access the contents of a
1466 cell object. Now, a ``cell_contents`` attribute has been added
1467 (closes patch #1170323).
1468
Tim Peterscf79aac2006-03-16 01:14:46 +00001469- Patch #1123430: Python's small-object allocator now returns an arena to
1470 the system ``free()`` when all memory within an arena becomes unused
1471 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1472 freed. Some applications will see a drop in virtual memory size now,
1473 especially long-running applications that, from time to time, temporarily
1474 use a large number of small objects. Note that when Python returns an
1475 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001476 platform C library will in turn return that memory to the operating system.
1477 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001478 appears to be effective at least on Microsoft C and gcc-based systems.
1479 Thanks to Evan Jones for hard work and patience.
1480
Georg Brandl533ff6f2006-03-08 18:09:27 +00001481- Patch #1434038: property() now uses the getter's docstring if there is
1482 no "doc" argument given. This makes it possible to legitimately use
1483 property() as a decorator to produce a read-only property.
1484
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001485- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1486 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1487 of requiring an int or long in slicing and a few other contexts, enabling
1488 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1489
Neal Norwitz995acdf2006-03-07 05:01:00 +00001490- Fixed various bugs reported by Coverity's Prevent tool.
1491
Brett Cannonbf364092006-03-01 04:25:17 +00001492- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1493 new exception base class, BaseException, which has a new message attribute.
1494 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1495 Raising a string exception now raises a DeprecationWarning.
1496
Thomas Woutersfb609f42006-02-28 16:37:25 +00001497- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1498 explicitly relative, using 'from .module import name' to mean 'from the same
1499 package as this module is in. Imports without dots still default to the
1500 old relative-then-absolute, unless 'from __future__ import
1501 absolute_import' is used.
1502
Brett Cannona7446e32006-02-27 23:39:10 +00001503- Properly check if 'warnings' raises an exception (usually when a filter set
1504 to "error" is triggered) when raising a warning for raising string
1505 exceptions.
1506
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001507- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001508 The name was removed from Include/code.h.
1509
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001510- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001511
Guido van Rossum1968ad32006-02-25 22:38:04 +00001512- Patch 1433928:
1513 - The copy module now "copies" function objects (as atomic objects).
1514 - dict.__getitem__ now looks for a __missing__ hook before raising
1515 KeyError.
1516
Tim Peters84ef21c2006-02-28 20:39:06 +00001517- PEP 343: with statement implemented. Needs ``from __future__ import
1518 with_statement``. Use of 'with' as a variable will generate a warning.
1519 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001520 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001521 The following objects have __context__ methods:
1522 - The built-in file type.
1523 - The thread.LockType type.
1524 - The following types defined by the threading module:
1525 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1526 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001527
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001528- Fix the encodings package codec search function to only search
1529 inside its own package. Fixes problem reported in patch #1433198.
1530
1531 Note: Codec packages should implement and register their own
1532 codec search function. PEP 100 has the details.
1533
Tim Peters9ea89d22006-06-04 03:26:02 +00001534- PEP 353: Using ``Py_ssize_t`` as the index type.
1535
1536- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1537 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1538 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1539 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1540 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001541
Neal Norwitzfc76d632006-01-10 06:03:13 +00001542- Patch #1400181, fix unicode string formatting to not use the locale.
1543 This is how string objects work. u'%f' could use , instead of .
1544 for the decimal point. Now both strings and unicode always use periods.
1545
Neal Norwitz671b9e32006-01-09 07:07:12 +00001546- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1547 configure would break checking curses.h.
1548
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001549- Bug #959576: The pwd module is now builtin. This allows Python to be
1550 built on UNIX platforms without $HOME set.
1551
Neal Norwitzc10978f2005-12-19 06:07:16 +00001552- Bug #1072182, fix some potential problems if characters are signed.
1553
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001554- Bug #889500, fix line number on SyntaxWarning for global declarations.
1555
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001556- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1557
Neal Norwitze7214a12005-12-18 05:03:17 +00001558- Support for converting hex strings to floats no longer works.
1559 This was not portable. float('0x3') now raises a ValueError.
1560
Barry Warsaw2a38a862005-12-18 01:27:35 +00001561- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001562 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001563 is now displayed in interactive prompt banner.
1564
Georg Brandlfa166682005-12-17 21:45:17 +00001565- Implementation of PEP 341 - Unification of try/except and try/finally.
1566 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001567 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001568
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001569- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1570 now encodes backslash correctly.
1571
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001572- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1573
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001574- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001575 and long longs.
1576
Neal Norwitz67715f02005-11-09 06:59:35 +00001577- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001578 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001579 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001580
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001581- Replaced most Unicode charmap codecs with new ones using the
1582 new Unicode translate string feature in the builtin charmap
1583 codec; the codecs were created from the mapping tables available
1584 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1585 encodings now include a mapping for the Apple logo)
1586
Tim Peterse3547fd2005-12-16 23:13:57 +00001587- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001588
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001589- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001590
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001591- A new AST parser implementation was completed. The abstract
1592 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001593 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001594
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001595- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001596 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1597
Neal Norwitz708e51a2005-10-03 04:48:15 +00001598- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1599
Neal Norwitz11bd1192005-10-03 00:54:56 +00001600- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1601 Provide a warning when a directory is passed on the command line.
1602
Neal Norwitz40d37812005-10-02 01:48:49 +00001603- Fix segfault with invalid coding.
1604
1605- SF bug #772896: unknown encoding results in MemoryError.
1606
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001607- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001608 supported a __len__() method which evaluated to False when the iterator
1609 was empty.
1610
Guido van Rossum630db602005-09-20 18:49:54 +00001611- On 64-bit platforms, when __len__() returns a value that cannot be
1612 represented as a C int, raise OverflowError.
1613
Skip Montanarof8948ca2005-09-19 03:54:46 +00001614- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001615 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001616
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001617- SF bug #893549: parsing keyword arguments was broken with a few format
1618 codes.
1619
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001620- Changes donated by Elemental Security to make it work on AIX 5.3
1621 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1622 bug #105470: test_pwd fails on 64bit system (Opteron).
1623
Guido van Rossum539c6622005-09-14 17:49:54 +00001624- Changes donated by Elemental Security to make it work on HP-UX 11 on
1625 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1626
Georg Brandl4550b8d2005-08-26 06:43:52 +00001627- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001628 (fixes bug #1119418).
1629
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001630- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1631
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001632- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1633 exceptions that cause a function to exit.
1634
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001635- The implementation of set() and frozenset() was revised to use its
1636 own internal data structure. Memory consumption is reduced by 1/3
1637 and there are modest speed-ups as well. The API is unchanged.
1638
Tim Petersde7990b2005-07-17 23:45:23 +00001639- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1640
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001641- SF bug #1229429: PyObject_CallMethod failed to decrement some
1642 reference counts in some error exit cases.
1643
Tim Petersecc6e6a2005-07-10 22:30:55 +00001644- SF bug #1185883: Python's small-object memory allocator took over
1645 a block managed by the platform C library whenever a realloc specified
1646 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001647 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001648 portable way to copy data from the C-managed block into Python's
1649 small-object space without risking a memory fault. Python's small-object
1650 realloc now leaves such blocks under the control of the platform C
1651 realloc.
1652
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001653- SF bug #1232517: An overflow error was not detected properly when
1654 attempting to convert a large float to an int in os.utime().
1655
Raymond Hettinger3296e692005-06-29 23:29:56 +00001656- SF bug #1224347: hex longs now print with lowercase letters just
1657 like their int counterparts.
1658
Michael W. Hudson188d4362005-06-20 16:52:57 +00001659- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1660 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1661 interpreter states; back out that fix and do a better job (see
1662 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1663 for a longer write-up of the problem).
1664
Michael W. Hudsondf888462005-06-03 14:41:55 +00001665- SF patch #1180995: marshal now uses a binary format by default when
1666 serializing floats.
1667
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001668- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1669 the routines that promise to produce IEEE 754 binary representations
1670 of floats now simply copy bytes around.
1671
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001672- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1673 278.
1674
Brett Cannonc3647ac2005-04-26 03:45:26 +00001675- patch #1109424: int, long, float, complex, and unicode now check for the
1676 proper magic slot for type conversions when subclassed. Previously the
1677 magic slot was ignored during conversion. Semantics now match the way
1678 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001679 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001680 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001681 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001682
Barry Warsawc8d907c2005-04-19 23:43:40 +00001683- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1684 NULL, now raise an AttributeError when attempting to set or delete the
1685 attribute. Previously a TypeError was raised, but this was inconsistent
1686 with the equivalent pure-Python implementation.
1687
Michael W. Hudson774479c2005-04-18 08:46:17 +00001688- It is now safe to call PyGILState_Release() before
1689 PyEval_InitThreads() (note that if there is reason to believe there
1690 are multiple threads around you still must call PyEval_InitThreads()
1691 before using the Python API; this fix is for extension modules that
1692 have no way of knowing if Python is multi-threaded yet).
1693
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001694- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1695 disabled caused a crash.
1696
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001697- Bug #1165306: instancemethod_new allowed the creation of a method
1698 with im_class == im_self == NULL, which caused a crash when called.
1699
Tim Petersecc6e6a2005-07-10 22:30:55 +00001700- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001701 fixes the crash seen in bug #1165761
1702
Raymond Hettinger96229b12005-03-11 06:49:40 +00001703- Added two new builtins, any() and all().
1704
Brett Cannon409d8f22005-03-05 06:47:57 +00001705- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001706 (e.g., ``class C(): pass`` is no longer a syntax error).
1707 Patch #1176012 added support to the 'parser' module and 'compiler' package
1708 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001709
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001710- Patch #1115086: Support PY_LONGLONG in structmember.
1711
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001712- Bug #1155938: new style classes did not check that __init__() was
1713 returning None.
1714
Tim Petersecc6e6a2005-07-10 22:30:55 +00001715- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001716 ('\') with a specific error message.
1717
Martin v. Löwisff232d72005-03-03 09:24:38 +00001718- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1719
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001720- Bug #1124295: the __name__ attribute of file objects was
1721 inadvertently made inaccessible in restricted mode.
1722
Tim Petersecc6e6a2005-07-10 22:30:55 +00001723- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001724 an ferror() call.
1725
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001726- min() and max() now support key= arguments with the same meaning as in
1727 list.sort().
1728
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001729- The peephole optimizer now performs simple constant folding in expressions:
1730 (2+3) --> (5).
1731
Raymond Hettingera422c342005-01-11 03:03:27 +00001732- set and frozenset objects can now be marshalled. SF #1098985.
1733
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001734- Bug #1077106: Poor argument checking could cause memory corruption
1735 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001736
Jeremy Hyltonab630502005-02-04 18:44:06 +00001737- The parser did not complain about future statements in illegal
1738 positions. It once again reports a syntax error if a future
1739 statement occurs after anything other than a doc string.
1740
Neil Schemenauercf52c072005-08-12 17:34:58 +00001741- Change the %s format specifier for str objects so that it returns a
1742 unicode instance if the argument is not an instance of basestring and
1743 calling __str__ on the argument returns a unicode instance.
1744
Tim Petersf4e69282006-02-27 17:15:31 +00001745- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1746 current thread state when the auto-GIL-state machinery knows about
1747 it (since the thread state is being deleted, continuing to remember it
1748 can't help, but can hurt if another thread happens to get created with
1749 the same thread id).
1750
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001751Extension Modules
1752-----------------
1753
Georg Brandl43f08a82006-03-31 18:01:16 +00001754- Patch #1380952: fix SSL objects timing out on consecutive read()s
1755
Neal Norwitz05a45592006-03-20 06:30:08 +00001756- Patch #1309579: wait3 and wait4 were added to the posix module.
1757
Anthony Baxterfa869072006-03-20 05:21:58 +00001758- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
1759 In addition, the existing ulaw code was updated.
1760
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001761- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00001762 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00001763
Neal Norwitz10be10c2006-03-16 06:50:13 +00001764- Everything under lib-old was removed. This includes the following modules:
1765 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00001766 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00001767 util, whatsound, whrandom, zmod
1768
1769- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1770
1771- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001772 is deprecated. The undocumented re.engine variable no longer exists.
1773
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001774- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00001941- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
1942 been renamed to have only a single underscore prefix. This was done to
1943 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001944
Nick Coghlan43832302006-04-23 17:04:07 +00001945- PEP 338: new module runpy defines a run_module function to support
1946 executing modules which provide access to source code or a code object
1947 via the PEP 302 import mechanisms.
1948

1957 in attribute values.
1958
Anthony Baxterc51ee692006-04-01 00:57:31 +00001959- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00001960 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00001961 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00001962 module will not be built.
1963
Tim Petersc17976e2006-04-01 00:26:53 +00001964- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
1965 aren't officially supported here, and trying to use them will probably
1966 raise an exception some day. But dicts have been allowed, and "mostly
1967 worked", so support for them won't go away without warning.
1968
Georg Brandl338ef7d2006-03-31 18:42:16 +00001969- Bug #1445068: getpass.getpass() can now be given an explicit stream

1987
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00001988- email 4.0 package now integrated. This is largely the same as the email 3.0
1989 package that was included in Python 2.3, except that PEP 8 module names are
1990 now used (e.g. mail.message instead of email.Message). The MIME classes
1991 have been moved to a subpackage (e.g. email.mime.text instead of
1992 email.MIMEText). The old names are still supported for now. Several
1993 deprecated Message methods have been removed and lots of bugs have been
1994 fixed. More details can be found in the email package documentation.
1995
Walter Dörwald40108c92006-03-27 08:15:44 +00001996- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
1997 (a subclass of tuple) that provides incremental decoders and encoders
1998 (a way to use stateful codecs without the stream API). Python functions
1999 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2000 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2001 have been added.

2004 a ValueError instead of a StopIteration now (like file and cString.String do).

2074
Neal Norwitz338e7862005-12-23 21:27:46 +00002075- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
2076 LoadError as documented, instead of IOError. For compatibility,
2077 LoadError subclasses IOError.
2078
Brett Cannon3cbd0382005-12-16 22:49:23 +00002079- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00002080 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2081 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2082 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2083 Ronald L. Rivest offered this advice for Python:
2084
2085 "The consensus of researchers in this area (at least as
2086 expressed at the NIST Hash Function Workshop 10/31/05),
2087 is that SHA-256 is a good choice for the time being, but
2088 that research should continue, and other alternatives may
2089 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002090
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002091- Added a subset of Fredrik Lundh's ElementTree package. Available

2210 work as expected.
2211
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002212- Bug #1163325: Decimal infinities failed to hash. Attempting to

Guido van Rossumd0641422005-02-03 15:01:24 +00002250- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2251 disables recursive traversal through instance attributes, which can
2252 be exploited in various ways.
2253
Tim Peterse3547fd2005-12-16 23:13:57 +00002254- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec

2268
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002269- Enhancements to the csv module:
2270
2271 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002272 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002273 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002274 + Dialect parameter parsing has been re-implemented to improve error
2275 reporting.
2276 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2277 dictates.
2278 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002279 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002280 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002281 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2282 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002283 + reader now allows \r characters to be quoted (previously it only allowed
2284 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002285 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002286 + Dialect classes passed to the module are no longer instantiated by
2287 the module before being parsed (the former validation scheme required
2288 this, but the mechanism was unreliable).
2289 + The dialect registry now contains instances of the internal
2290 C-coded dialect type, rather than references to python objects.
2291 + the internal c-coded dialect type is now immutable.
2292 + register_dialect now accepts the same keyword dialect specifications
2293 as the reader and writer, allowing the user to register dialects
2294 without first creating a dialect class.
2295 + a configurable limit to the size of parsed fields has been added -
2296 previously, an unmatched quote character could result in the entire
2297 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002298 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002299 the parser field size limit (returning the former limit). The initial
2300 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002301 + A line_num attribute has been added to the reader object, which tracks
2302 the number of lines read from the source iterator. This is not
2303 the same as the number of records returned, as records can span
2304 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002305 + reader and writer objects were not being registered with the cyclic-GC.
2306 This has been fixed.
2307
Brett Cannone6539c42005-01-08 02:43:53 +00002308- _DummyThread objects in the threading module now delete self.__block that is
2309 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2310 lock primitives tend to be limited in number and thus should not be wasted on
2311 a _DummyThread object. Fixes bug #1089632.
2312
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002313- The imghdr module now detects Exif files.
2314
Raymond Hettinger6065d322004-12-20 23:51:53 +00002315- StringIO.truncate() now correctly adjusts the size attribute.
2316 (Bug #951915).
2317
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002318- locale.py now uses an updated locale alias table (built using
2319 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2320 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002321 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002322
Raymond Hettinger3557f422004-12-07 12:02:02 +00002323- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2324
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002325- the pickle module no longer accepts the deprecated None option in the
2326 args tuple returned by __reduce__().
2327
Brett Cannon84667c02004-12-07 03:25:18 +00002328- optparse now optionally imports gettext. This allows its use in setup.py.
2329
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002330- the pickle module no longer uses the deprecated bin parameter.
2331
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002332- the shelve module no longer uses the deprecated binary parameter.
2333

2335
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002336- the filecmp module no longer uses the deprecated use_statcache argument.
2337
Raymond Hettinger664347b2004-12-04 21:21:53 +00002338- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2339 extended or overridden by subclasses. Formerly, the subclassed method would
2340 be ignored by the rest of the module. (Bug #1078905).
2341
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002342- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002343 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002344
Walter Dörwald36733692004-12-22 12:50:50 +00002345- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2346 once when a size argument is given. This prevents a buffer overflow in the
2347 tokenizer with very long source lines.
2348
Barry Warsaw538561e2006-01-01 21:48:54 +00002349- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2350 immediately after creating the object, without any intervening
2351 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002352
Skip Montanaro05885812005-01-16 20:48:27 +00002353- The reconvert.quote function can now emit triple-quoted strings. The
2354 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002355
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002356- ``UserString.MutableString`` now supports negative indices in
2357 ``__setitem__`` and ``__delitem__``
2358
Greg Ward40407942005-03-05 02:53:17 +00002359- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2360 correctly.
2361
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002362- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2363 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2364 character even if the user has passed a size parameter to get a proper
2365 line ending. Remove the special handling of a "\r\n" that has been split
2366 between two lines.
2367
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002368- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2369 about illegal code points. The codec now supports PEP 293 style error
2370 handlers.
2371
Walter Dörwald78a78b02005-09-01 12:04:29 +00002372- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002373 from the input stream, so that the output is a byte string in the correct
2374 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002375
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002376- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2377 considering it exactly like a '*'.
2378
Walter Dörwald007f8df2005-10-09 19:42:27 +00002379- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2380 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002381
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002382- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2383
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002384- Patch #1413711: Certain patterns of differences were making difflib
2385 touch the recursion limit.
2386
Walter Dörwald58917a62006-03-31 15:26:22 +00002387- Bug #947906: An object oriented interface has been added to the calendar
2388 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002389 called as a script (e.g. via ``python -mcalendar``). Localized month and
2390 weekday names can be ouput (even if an exotic encoding is used) using
2391 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002392
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002393Build
2394-----
2395
Neal Norwitz602d3392006-03-31 08:21:40 +00002396- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2397 by using -mieee gcc option.
2398
Martin v. Löwis86d66262006-02-17 08:40:11 +00002399- Patch #1432345: Make python compile on DragonFly.
2400
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002401- Build support for Win64-AMD64 was added.
2402
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002403- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2404
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002405- Patch #881820: look for openpty and forkpty also in libbsd.
2406
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002407- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2408 The zlib module is now builtin on Windows.
2409
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002410- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2411
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002412- Bug #1189330: configure did not correctly determine the necessary
2413 value of LINKCC if python was built with GCC 4.0.
2414
Trent Mick8321b422005-07-26 02:29:21 +00002415- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2416 vulnerability in zlib 1.2.1 and 1.2.2.
2417
Brett Cannon08cd5982005-04-24 22:26:38 +00002418- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2419 flags that change binary compatibility. Changes were also made to
2420 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002421 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002422
Bob Ippolitoed233462005-03-29 13:47:59 +00002423- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2424 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2425 no longer exists). This configure patch makes things right.
2426
Martin v. Löwise2713be2005-03-08 15:03:08 +00002427- Bug #1158607: Build with --disable-unicode again.
2428
Brett Cannon46d96232005-02-16 00:07:19 +00002429- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2430 defined. Discovered as a result of not being able to build on OS X.
2431
Brett Cannon516592f2004-12-07 00:42:59 +00002432- setup.py now uses the directories specified in LDFLAGS using the -L option
2433 and in CPPFLAGS using the -I option for adding library and include
2434 directories, respectively, for compiling extension modules against. This has
2435 led to the core being compiled using the values in CPPFLAGS. It also removes
2436 the need for the special-casing of both DarwinPorts and Fink for darwin since
2437 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2438 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2439 Fink, ``-I/opt/local/include`` for DarwinPorts).
2440
Brett Cannon43802422005-02-10 20:48:03 +00002441- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2442 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2443 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2444 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002446C API
2447-----
2448
Tim Petersc9d78aa2006-03-26 23:27:58 +00002449- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2450 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2451 is obtained via the ``PyObject_`` family, it must be released via the
2452 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2453 always been officially true, but when Python's small-object allocator was
2454 introduced, an attempt was made to cater to a few extension modules
2455 discovered at the time that obtained memory via ``PyObject_New`` but
2456 released it via ``PyMem_DEL``. It's years later, and if such code still
2457 exists it will fail now (probably with segfaults, but calling wrong
2458 low-level memory management functions can yield many symptoms).
2459
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002460- Added a C API for set and frozenset objects.
2461
Raymond Hettinger66517482004-12-03 11:45:13 +00002462- Removed PyRange_New().
2463
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002464- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2465 mapping argument now. This string is used as a mapping table. Byte values
2466 greater than the length of the string and 0xFFFE are treated as undefined
2467 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002474
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002475- Patch #1276356: New resource "urlfetch" is implemented. This enables
