Neal Norwitz0bcafac2006-09-11 08:51:17 +0000349- Make _PyGILState_NoteThreadState() static, it was not used anywhere
350 outside of pystate.c and should not be necessary.
351
Brett Cannon19d76c52006-09-09 07:18:44 +0000352- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
353 allows calling unicode() on exceptions classes directly to succeed.

Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000370- The return tuple from str.rpartition(sep) is (tail, sep, head) where
371 head is the original string if sep was not found.
372
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000373- Bug #1520864: unpacking singleton tuples in list comprehensions and
374 generator expressions (x for x, in ... ) works again. Fixing this problem
375 required changing the .pyc magic number. This means that .pyc files
376 generated before 2.5c2 will be regenerated.

479Core and builtins
480-----------------
481
Neal Norwitz24b6f202006-09-05 04:43:56 +0000482- Fix infinite recursion when subclassing long and overriding __hash__.
483
484- Fix concatenation (+=) of long strings.
485
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000486- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000487 compared equal or unequal to a string and a UnicodeDecodeError
488 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000489
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000490 Instead, the equal (==) and unequal (!=) comparison operators will
491 now issue a UnicodeWarning and interpret the two objects as
492 unequal. The UnicodeWarning can be filtered as desired using
493 the warning framework, e.g. silenced completely, turned into an
494 exception, logged, etc.
495
496 Note that compare operators other than equal and unequal will still
497 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000498
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000499- Fix segfault when doing string formatting on subclasses of long.
500
501- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
502 with new-style classes.
503
504- Fix bug related to __len__ functions returning negative values with
505 classic classes.
506
507- Patch #1538606, Fix __index__() clipping. There were some problems
508 discovered with the API and how integers that didn't fit into Py_ssize_t
509 were handled. This patch attempts to provide enough alternatives
510 to effectively use __index__.
511
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000512- Bug #1536021: __hash__ may now return long int; the final hash
513 value is obtained by invoking hash on the long int.
514
Thomas Hellerab1049c2006-08-08 17:37:00 +0000515- Bug #1536786: buffer comparison could emit a RuntimeWarning.

518 sys.stdin is closed.
519
Thomas Heller74d36f02006-08-04 18:17:40 +0000520- On Windows, the PyErr_Warn function is now exported from
521 the Python dll again.
522
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000523- Bug #1191458: tracing over for loops now produces a line event
524 on each iteration. Fixing this problem required changing the .pyc
525 magic number. This means that .pyc files generated before 2.5c1
526 will be regenerated.
527
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000528- Bug #1333982: string/number constants were inappropriately stored
529 in the byte code and co_consts even if they were not used, ie
530 immediately popped off the stack.
531
Georg Brandle9462c72006-08-04 18:03:37 +0000532- Fixed a reference-counting problem in property().

536-------
537
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000538- Fix a bug in the ``compiler`` package that caused invalid code to be
539 generated for generator expressions.
540
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000541- The distutils version has been changed to 2.5.0. The change to
542 keep it programmatically in sync with the Python version running
543 the code (introduced in 2.5b3) has been reverted. It will continue
544 to be maintained manually as static string literal.
545
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000546- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000547 and this cannot be converted to the required C type, an exception is
548 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000549 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000550
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000551- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000552 an exception.
553
Tim Peterscbdd3502006-09-05 01:47:53 +0000554- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000555 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000556 workarounds for clocks with low resolution, to stop the code yielding
557 duplicate UUIDs.
558
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000559- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
560 before raising SystemExit, allowing IDLE to honor quit() and exit().
561
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000562- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.

Georg Brandl7a1af772006-08-14 21:55:28 +0000564- Patch #1536071: trace.py should now find the full module name of a
565 file correctly even on Windows.
566
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000567- logging's atexit hook now runs even if the rest of the module has
568 already been cleaned up.
569
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000570- Bug #1112549, fix DoS attack on cgi.FieldStorage.

588
Thomas Heller1ce433e2006-08-14 16:20:04 +0000589- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
590 '-no-stack-protector' compiler flag for OpenBSD has been removed.
591
Thomas Heller86720042006-08-14 11:17:48 +0000592- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
593 uses the _as_parameter_ attribute when objects are passed to foreign
594 function calls. The ctypes version number was changed to 1.0.1.
595
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000596- Bug #1530559, struct.pack raises TypeError where it used to convert.
597 Passing float arguments to struct.pack when integers are expected
598 now triggers a DeprecationWarning.

636
Tim Peters4643c2f2006-08-10 22:45:34 +0000637- Bug #1069160. Internal correctness changes were made to
638 ``PyThreadState_SetAsyncExc()``. A test case was added, and
639 the documentation was changed to state that the return value
640 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +0000643What's New in Python 2.5 beta 3?
644================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000645
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000646*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000647
648Core and builtins
649-----------------
650
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000651- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000652 returned a long (see PEP 353).
653
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000654- Bug #1515471: string.replace() accepts character buffers again.
655
Neal Norwitz07aadb12006-07-30 06:55:48 +0000656- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
657 This provides the proper warning for struct.pack().
658 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
659
Neal Norwitz0d62a062006-07-30 06:53:31 +0000660- Patch #1531113: Fix augmented assignment with yield expressions.
661 Also fix a SystemError when trying to assign to yield expressions.
662
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000663- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
664 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
665 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
666 excessive filesystem operations during imports.
667
Tim Petersbc24eee2006-07-27 01:14:53 +0000668- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
669 operations on signed longs that are formally undefined by C.
670 Unfortunately, at least one compiler now cares about that, so complicated
671 the code to make that compiler happy again.
672
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000673- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
674
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000675- Patch #1232023: Stop including current directory in search
676 path on Windows.
677
Neal Norwitze1fdb322006-07-21 05:32:28 +0000678- Fix some potential crashes found with failmalloc.
679
Neal Norwitze7563102006-07-17 01:00:16 +0000680- Fix warnings reported by Klocwork's static analysis tool.
681
Neal Norwitz84be93b2006-07-16 01:50:38 +0000682- Bug #1512814, Fix incorrect lineno's when code within a function
683 had more than 255 blank lines.
684
Georg Brandl9dceedb2006-07-12 15:31:17 +0000685- Patch #1521179: Python now accepts the standard options ``--help`` and
686 ``--version`` as well as ``/?`` on Windows.
687
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000688- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000689 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000690 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000691
Tim Peters112aad32006-07-19 00:03:19 +0000692- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000693 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000694 new ``sys._current_frames()`` returns a dictionary with one entry,
695 mapping the faux "thread id" 0 to the current frame.
696
Ronald Oussoren3075e162006-07-25 20:28:55 +0000697- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000698
Ronald Oussoren3075e162006-07-25 20:28:55 +0000699
Neal Norwitza1f10902006-07-12 07:28:29 +0000700Library
701-------
702
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000703- Correction of patch #1455898: In the mbcs decoder, set final=False
704 for stream decoder, but final=True for the decode function.
705
Georg Brandl07fec3a2006-08-01 18:49:24 +0000706- os.urandom no longer masks unrelated exceptions like SystemExit or
707 KeyboardInterrupt.
708
Tim Peters4643c2f2006-08-10 22:45:34 +0000709- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000710 shutil.copytree on Windows
711
Georg Brandle34ac7c2006-07-30 11:07:23 +0000712- Bug #1002398: The documentation for os.path.sameopenfile now correctly
713 refers to file descriptors, not file objects.
714
Tim Peterscbdd3502006-09-05 01:47:53 +0000715- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000716 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000717 #1513611, and probably others.
718
Georg Brandledd9b0d2006-07-29 09:33:26 +0000719- Bug #1441397: The compiler module now recognizes module and function
720 docstrings correctly as it did in Python 2.4.
721
Tim Peters6f681472006-07-27 23:44:37 +0000722- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
723 lost that tests are sorted by name before being run. This rarely
724 matters for well-written tests, but can create baffling symptoms if
725 side effects from one test to the next affect outcomes. ``DocTestFinder``
726 has been changed to sort the list of tests it returns.
727
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000728- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000729 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000730
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000731- Bug #978833: Really close underlying socket in _socketobject.close.
732
Georg Brandldb232dc2006-08-20 13:15:43 +0000733- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
734 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000735
Georg Brandlcf0c1722006-07-26 07:23:32 +0000736- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
737 to recursive calls and call it with the failing package name.
738
Martin v. Löwis0b483032006-07-25 09:53:12 +0000739- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
740
Georg Brandlc13c34c2006-07-24 14:09:56 +0000741- Patch #1515343: Fix printing of deprecated string exceptions with a
742 value in the traceback module.
743
Greg Ward48fae7a2006-07-23 16:05:51 +0000744- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
745
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000746- Patch #1524429: Use repr() instead of backticks in Tkinter again.
747
Brett Cannoncaebe222006-07-18 04:41:36 +0000748- Bug #1520914: Change time.strftime() to accept a zero for any position in its
749 argument tuple. For arguments where zero is illegal, the value is forced to
750 the minimum value that is correct. This is to support an undocumented but
751 common way people used to fill in inconsequential information in the time
752 tuple pre-2.4.
753
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000754- Patch #1220874: Update the binhex module for Mach-O.
755
Barry Warsawb110bad2006-07-21 14:51:07 +0000756- The email package has improved RFC 2231 support, specifically for
757 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
758 (name*0=<blah>) parameter continuations. This may change the types of
759 values returned from email.message.Message.get_param() and friends.
760 Specifically in some cases where non-encoded continuations were used,
761 get_param() used to return a 3-tuple of (None, None, string) whereas now it
762 will just return the string (since non-encoded continuations don't have
763 charset and language parts).
764
765 Also, whereas % values were decoded in all parameter continuations, they are
766 now only decoded in encoded parameter parts.
767
Ronald Oussoren3075e162006-07-25 20:28:55 +0000768- Bug #1517990: IDLE keybindings on MacOS X now work correctly
769
770- Bug #1517996: IDLE now longer shows the default Tk menu when a
771 path browser, class browser or debugger is the frontmost window on MacOS X
772
Barry Warsaw00decd72006-07-27 23:43:15 +0000773- Patch #1520294: Support for getset and member descriptors in types.py,
774 inspect.py, and pydoc.py. Specifically, this allows for querying the type
775 of an object against these built-in types and more importantly, for getting
776 their docstrings printed in the interactive interpreter's help() function.
777
Ronald Oussoren3075e162006-07-25 20:28:55 +0000778
Neal Norwitza1f10902006-07-12 07:28:29 +0000779Extension Modules
780-----------------
781
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000782- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
783 a socket operation on a socket with a timeout, the exception will be
784 caught correctly. Previously, the exception was not caught.
785
Thomas Heller1393d6a2006-07-28 21:43:20 +0000786- Patch #1529514: The _ctypes extension is now compiled on more
787 openbsd target platforms.
788
Tim Peters9cab5932006-07-28 00:30:00 +0000789- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
790 a memory leak, affecting pickles and deep copies.
791
Tim Petersbc24eee2006-07-27 01:14:53 +0000792- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000793 Paul Eggert.
794
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000795- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
796
Thomas Hellerce049a02006-07-14 17:51:14 +0000797- Patch #1521817: Index range checking on ctypes arrays containing
798 exactly one element enabled again. This allows iterating over these
799 arrays, without the need to check the array size before.
800
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000801- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000802 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000803 /dev/null in certain cases; this is now fixed.
804
Thomas Heller47d7a062006-07-12 08:43:47 +0000805- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
806 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000807
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000808- Because of a misspelled preprocessor symbol, ctypes was always
809 compiled without thread support; this is now fixed.
810
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000811- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
812 methods now allow their database parameter to be None as the
813 sleepycat API allows.
814
Matt Flemingec926502006-07-28 11:27:27 +0000815- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
816 bluetooth API compared with Linux and FreeBSD.
817
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000818Tests
819-----
820
821- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
822 how long the test file should take to play. Now accepts taking 2.93 secs
823 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
824
Georg Brandl4793aa32006-07-28 18:31:39 +0000825- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
826 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
827 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +0000828
Martin v. Löwis0907f4d2006-07-30 14:09:47 +0000829Build
830-----
831
832- Bug #1439538: Drop usage of test -e in configure as it is not portable.
833
Ronald Oussoren26cad082006-08-01 21:00:57 +0000834Mac
835---
836
837- PythonLauncher now works correctly when the path to the script contains
838 characters that are treated specially by the shell (such as quotes).
839
840- Bug #1527397: PythonLauncher now launches scripts with the working directory
841 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000842 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000843 expect.

851Core and builtins
852-----------------
853
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000854- Bug #1441486: The literal representation of -(sys.maxint - 1)
855 again evaluates to a int object, not a long.
856
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000857- Bug #1501934: The scope of global variables that are locally assigned
858 using augmented assignment is now correctly determined.
859
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000860- Bug #927248: Recursive method-wrapper objects can now safely
861 be released.
862
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000863- Bug #1417699: Reject locale-specific decimal point in float()
864 and atof().
865
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000866- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
867 omit a default "error" argument for NULL pointer. This allows
868 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000869
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000870- Bug #1519018: 'as' is now validated properly in import statements.
871
Neal Norwitz28746ab2006-07-09 22:14:42 +0000872- On 64 bit systems, int literals that use less than 64 bits are
873 now ints rather than longs.
874
Neal Norwitzed657552006-07-10 00:04:44 +0000875- Bug #1512814, Fix incorrect lineno's when code at module scope
876 started after line 256.
877
Tim Peters32a83612006-07-10 21:08:24 +0000878- New function ``sys._current_frames()`` returns a dict mapping thread
879 id to topmost thread stack frame. This is for expert use, and is
880 especially useful for debugging application deadlocks. The functionality
881 was previously available in Fazal Majid's ``threadframe`` extension
882 module, but it wasn't possible to do this in a wholly threadsafe way from
883 an extension.
884
Georg Brandlad29e632006-06-21 17:45:17 +0000885Library
886-------
887
Martin v. Löwis77621582006-07-30 13:27:31 +0000888- Bug #1257728: Mention Cygwin in distutils error message about a missing
889 VS 2003.
890
Martin v. Löwis06c68b82006-07-10 22:11:28 +0000891- Patch #1519566: Update turtle demo, make begin_fill idempotent.
892
Tim Peters32a83612006-07-10 21:08:24 +0000893- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +0000894 environment variable to be set in order to the SDK environment
895 for finding the compiler, include files, etc.
896
Martin v. Löwis388a8c22006-07-06 19:28:03 +0000897- Bug #1515998: Properly generate logical ids for files in bdist_msi.

Nick Coghlan2d792252006-07-06 13:47:18 +0000899- warnings.py now ignores ImportWarning by default
900
Thomas Woutersadd19112006-07-05 11:03:49 +0000901- string.Template() now correctly handles tuple-values. Previously,
902 multi-value tuples would raise an exception and single-value tuples would
903 be treated as the value they contain, instead.
904
Martin v. Löwisede77f52006-07-03 13:01:35 +0000905- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

918 is created.
919
Martin v. Löwis7596e832006-07-01 15:33:37 +0000920- Bug #1513223: .close() of a _socketobj now releases the underlying
921 socket again, which then gets closed as it becomes unreferenced.
922

930
Brett Cannon53ab5b72006-06-22 16:49:14 +0000931- Bug #1510580: The 'warnings' module improperly required that a Warning
932 category be either a types.ClassType and a subclass of Warning. The proper
933 check is just that it is a subclass with Warning as the documentation states.
934
Georg Brandlad29e632006-06-21 17:45:17 +0000935- The compiler module now correctly compiles the new try-except-finally
936 statement (bug #1509132).
937
Neal Norwitz60373cd2006-06-22 06:30:50 +0000938- The wsgiref package is now installed properly on Unix.
939

941 shutdown when fileConfig() was called multiple times.
942
Gerhard Häring762fbd32006-07-02 17:48:30 +0000943- The sqlite3 module did cut off data from the SQLite database at the first
944 null character before sending it to a custom converter. This has been fixed
945 now.
946

948-----------------
949
Tim Peters112aad32006-07-19 00:03:19 +0000950- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
951 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
952 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000953
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000954- Assigning None to pointer type fields in ctypes structures possible
955 overwrote the wrong fields, this is fixed now.
956
957- Fixed a segfault in _ctypes when ctypes.wintypes were imported
958 on non-Windows platforms.
959
960- Bug #1518190: The ctypes.c_void_p constructor now accepts any
961 integer or long, without range checking.
962
963- Patch #1517790: It is now possible to use custom objects in the ctypes
964 foreign function argtypes sequence as long as they provide a from_param
965 method, no longer is it required that the object is a ctypes type.
966
967- The '_ctypes' extension module now works when Python is configured
968 with the --without-threads option.
969
Martin v. Löwisee1e06d2006-07-02 18:44:00 +0000970- Bug #1513646: os.access on Windows now correctly determines write
971 access, again.
972
Neal Norwitz0f8b31a2006-06-28 06:28:31 +0000973- Bug #1512695: cPickle.loads could crash if it was interrupted with

985
Tim Peters32a83612006-07-10 21:08:24 +0000986- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +0000987 Previously, the slight difference could cause compilation errors of the
988 'zlib' module on systems with more than one version of zlib.
989
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +0000990- The MSI compileall step was fixed to also support a TARGETDIR
991 with spaces in it.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001020
1021Core and builtins
1022-----------------
1023
Georg Brandla56b9152006-06-19 06:35:54 +00001024- Patch #1507676: Error messages returned by invalid abstract object operations
1025 (such as iterating over an integer) have been improved and now include the
1026 type of the offending object to help with debugging.
1027
Brett Cannonea3912b2006-06-13 21:46:41 +00001028- Bug #992017: A classic class that defined a __coerce__() method that returned
1029 its arguments swapped would infinitely recurse and segfault the interpreter.
1030
Neal Norwitz909eb122006-06-12 02:13:21 +00001031- Fix the socket tests so they can be run concurrently.
1032
Neal Norwitzb9845e72006-06-12 02:11:18 +00001033- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001034 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001035
Brett Cannon22565aa2006-06-09 22:31:23 +00001036- Bug #532646: object.__call__() will continue looking for the __call__
1037 attribute on objects until one without one is found. This leads to recursion
1038 when you take a class and set its __call__ attribute to an instance of the
1039 class. Originally fixed for classic classes, but this fix is for new-style.
1040 Removes the infinite_rec_3 crasher.
1041
Georg Brandl24250812006-06-09 18:45:48 +00001042- The string and unicode methods startswith() and endswith() now accept
1043 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1044
Brett Cannonde3b0522006-06-08 17:00:45 +00001045- Buffer objects, at the C level, never used the char buffer
1046 implementation even when the char buffer for the wrapped object was
1047 explicitly requested (originally returned the read or write buffer).
1048 Now a TypeError is raised if the char buffer is not present but is
1049 requested.
1050
Georg Brandlddbaa662006-06-04 21:56:52 +00001051- Patch #1346214: Statements like "if 0: suite" are now again optimized
1052 away like they were in Python 2.4.
1053
Georg Brandlb7c8f542006-05-27 12:30:25 +00001054- Builtin exceptions are now full-blown new-style classes instead of
1055 instances pretending to be classes, which speeds up exception handling
1056 by about 80% in comparison to 2.5a2.
1057
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001058- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1059 Unicode 4.1.
1060
Georg Brandlf4ef1162006-05-26 18:03:31 +00001061- Patch #921466: sys.path_importer_cache is now used to cache valid and
1062 invalid file paths for the built-in import machinery which leads to
1063 fewer open calls on startup.
1064
Tim Peters696cf432006-05-24 21:10:40 +00001065- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1066 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1067 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1068 the number of input digits (it was and remains linear-time for bases
1069 2, 4, 8, 16 and 32).
1070
Tim Petersb713ec22006-05-23 18:45:30 +00001071- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1072 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1073 an integer close to ``sys.maxint``. This was repaired by patch
1074 #1335972, which also gives a nice speedup.
1075
Richard Jonescebbefc2006-05-23 18:28:17 +00001076- Patch #1337051: reduced size of frame objects.
1077
1078- PyErr_NewException now accepts a tuple of base classes as its
1079 "base" parameter.
1080
Richard Jones7c88dcc2006-05-23 10:37:38 +00001081- Patch #876206: function call speedup by retaining allocated frame
1082 objects.
1083
Georg Brandl7b90e162006-05-18 07:01:27 +00001084- Bug #1462152: file() now checks more thoroughly for invalid mode
1085 strings and removes a possible "U" before passing the mode to the
1086 C library function.
1087
Neal Norwitz1004a532006-05-15 07:17:23 +00001088- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1089
Neal Norwitz373f0a72006-05-15 07:04:36 +00001090- Bug #1487966: Fix SystemError with conditional expression in assignment
1091
Martin v. Löwis879768d2006-05-11 13:28:43 +00001092- WindowsError now has two error code attributes: errno, which carries
1093 the error values from errno.h, and winerror, which carries the error
1094 values from winerror.h. Previous versions put the winerror.h values
1095 (from GetLastError()) into the errno attribute.
1096
Martin v. Löwis77736712006-05-04 05:51:03 +00001097- Patch #1475845: Raise IndentationError for unexpected indent.
1098
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001099- Patch #1479181: split open() and file() from being aliases for each other.
1100
Tim Peters44bd9862006-06-01 13:49:23 +00001101- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1102 methods were always silently ignored by dictionaries when comparing keys.
1103 They are now passed through (except when using the C API function
1104 ``PyDict_GetItem()``, whose semantics did not change).
1105
1106- Bug #1456209: In some obscure cases it was possible for a class with a
1107 custom ``__eq__()`` method to confuse dict internals when class instances
1108 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1109 No, you don't have any code that did this ;-)

1117
Brett Cannon6ee7d012006-06-08 16:23:04 +00001118- Change binascii.hexlify to accept a read-only buffer instead of only a char
1119 buffer and actually follow its documentation.
1120
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001121- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1122
Nick Coghlanc649ec52006-05-29 12:43:05 +00001123- Patch #1478788 (modified version): The functional extension module has
1124 been renamed to _functools and a functools Python wrapper module added.
1125 This provides a home for additional function related utilities that are
1126 not specifically about functional programming. See PEP 309.
1127
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001128- Patch #1493701: performance enhancements for struct module.

1136 enabled builds on Windows and systems with Posix threads support.
1137
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001138- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1139 (up to the system limit of 32K characters).
1140
1141- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1142 As a result, these functions now raise WindowsError instead of OSError.
1143
Tim Peters7a822da2006-05-25 21:50:17 +00001144- ``time.clock()`` on Win64 should use the high-performance Windows
1145 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1146 Windows platforms).
1147
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001148- Calling Tk_Init twice is refused if the first call failed as that
1149 may deadlock.
1150
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001151- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1152 accept it without potentially using an uninitialized pointer.
1153
1154- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1155 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

1165 results. It could previously incorrectly return 0 in some cases.
1166 Fixes SF bug 1493322 (pybsddb bug 1184012).
1167
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001168- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1169 aborts the db transaction safely when a modifier callback fails.
1170 Fixes SF python patch/bug #1408584.
1171
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001172- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001173 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001174 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1175 database calls that would previously deadlock. [SF python bug #775414]

Georg Brandl2605ca82006-06-14 06:08:31 +00001201- Bug #1339007: Shelf objects now don't raise an exception in their
1202 __del__ method when initialization failed.
1203
Martin v. Löwisd8251432006-06-14 05:21:04 +00001204- Patch #1455898: The MBCS codec now supports the incremental mode for
1205 double-byte encodings.
1206
Tim Peters43898b42006-06-14 04:09:25 +00001207- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1208 guarantee that adjacent triples in the return list always describe
1209 non-adjacent blocks. Previously, a pair of matching blocks could end
1210 up being described by multiple adjacent triples that formed a partition
1211 of the matching pair.
1212
Greg Ward0e0c9f42006-06-11 16:24:11 +00001213- Bug #1498146: fix optparse to handle Unicode strings in option help,
1214 description, and epilog.
1215
Greg Wardd1c797e2006-06-11 14:42:41 +00001216- Bug #1366250: minor optparse documentation error.
1217
Greg Ward7f547402006-06-11 00:40:49 +00001218- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1219 clarify docs.
1220
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001221- The wsgiref package has been added to the standard library.
1222
Nick Coghlan676725d2006-06-08 13:54:49 +00001223- The functions update_wrapper() and wraps() have been added to the functools
1224 module. These make it easier to copy relevant metadata from the original
1225 function when writing wrapper functions.
1226
Tim Petersd6a9eef2006-06-05 01:48:21 +00001227- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1228 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001229
Martin v. Löwis3f767792006-06-04 19:36:28 +00001230- Patch #1359618: Speed up charmap encoder by using a trie structure
1231 for lookup.
1232
Tim Petersd609b1a2006-06-02 23:22:51 +00001233- The functions in the ``pprint`` module now sort dictionaries by key
1234 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1235 if and only if its display required more than one line, although that
1236 wasn't documented. The new behavior increases predictability; e.g.,
1237 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1238
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001239- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1240 (thanks for J. J. Lee).
1241
Georg Brandl2b330372006-05-28 20:23:12 +00001242- Patch #1496206: improve urllib2 handling of passwords with respect to
1243 default HTTP and HTTPS ports.
1244
George Yoshidaf3c65de2006-05-28 16:39:09 +00001245- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1246
Bob Ippolito7298f272006-05-23 18:43:47 +00001247- Patch #1281707: speed up gzip.readline.
1248
Georg Brandlb89316f2006-05-17 15:51:16 +00001249- Patch #1180296: Two new functions were added to the locale module:
1250 format_string() to get the effect of "format % items" but locale-aware,
1251 and currency() to format a monetary number with currency sign.
1252
Georg Brandle3a25832006-05-17 14:56:04 +00001253- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1254 and several features added, such as speed and geometry control.
1255
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001256- Patch #1488881: add support for external file objects in bz2 compressed
1257 tarfiles.
1258
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001259- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1260 stdout arguments, making it possible to redirect input and output
1261 for remote debugging.
1262
1263- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1264 a couple of issues, notably handling of long file names using the
1265 GNU LONGNAME extension.
1266
1267- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1268 new flag when ``name`` is already the name of an option flag.
1269
1270- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1271 package.
1272
1273- Patch #1472854: make the rlcompleter.Completer class usable on non-
1274 UNIX platforms.
1275
1276- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1277
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001278- Bug #1472827: correctly escape newlines and tabs in attribute values in
1279 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001309What's New in Python 2.5 alpha 2?
1310=================================
1311
1312*Release date: 27-APR-2006*
1313
1314Core and builtins
1315-----------------
1316
Thomas Heller1b046642006-04-18 18:51:06 +00001317- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1318 by converting these apis from macros into exported functions again:
1319
1320 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1321 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1322 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1323 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1324 PyRun_String Py_CompileString
1325
Martin v. Löwis45294a92006-04-18 06:24:08 +00001326- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1327
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001328- All uses of PyStructSequence_InitType have been changed to initialize
1329 the type objects only once, even if the interpreter is initialized
1330 multiple times.
1331
Neal Norwitz61546162006-04-14 05:20:28 +00001332- Bug #1454485, array.array('u') could crash the interpreter. This was
1333 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1334 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1335
1336- Py_UNICODE is unsigned. It was always documented as unsigned, but
1337 due to a bug had a signed value in previous versions.
1338
Tim Peters3a5e8b12006-04-11 01:44:07 +00001339- Patch #837242: ``id()`` of any Python object always gives a positive
1340 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1341 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001342 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001343 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001344
Tim Peters3a5e8b12006-04-11 01:44:07 +00001345 def __hash__(self):
1346 return id(self) # WRONG
1347
1348 because a hash result must be a (short) Python int but it was always
1349 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001350 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001351 was always usable as a hash value before this patch. That's no longer
1352 necessarily so.
1353
1354- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001355 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001356 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001357 #1454844)
1358
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001359- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1360 involving generators that have paused outside of any ``try`` or ``with``
1361 blocks. (In 2.5a1, a paused generator that was part of a reference
1362 cycle could not be garbage collected, regardless of whether it was
1363 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001364
Anthony Baxter51bcb682006-04-05 14:51:42 +00001365Extension Modules

1367
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001368- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1369 is a macro.
1370
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001371- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1372 fails with an error condition.
1373
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001374- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1375
1376- Bug #1117761: bsddb.*open() no longer raises an exception when using
1377 the cachesize parameter.
1378
1379- Bug #1149413: bsddb.*open() no longer raises an exception when using
1380 a temporary db (file=None) with the 'n' flag to truncate on open.
1381
1382- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1383 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001384
Armin Rigoa9017c32006-04-19 11:50:27 +00001385- Patch #1062014: AF_UNIX sockets under Linux have a special
1386 abstract namespace that is now fully supported.

Peter Astrand7d1d4362006-07-14 14:04:45 +00001391- Bug #1223937: subprocess.CalledProcessError reports the exit status
1392 of the process using the returncode attribute, instead of
1393 abusing errno.
1394
Tim Peters711bf302006-04-25 03:31:36 +00001395- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1396 a doctest to be skipped (the code is not run, and the expected output
1397 or exception is ignored).
1398
Nick Coghlanda2268f2006-04-24 04:37:15 +00001399- Fixed contextlib.nested to cope with exceptions being raised and
1400 caught inside exit handlers.
1401
Greg Wardab05edc2006-04-23 03:47:58 +00001402- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1403 hex, octal, or binary; add ``append_const`` action; keep going if
1404 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1405 added ``epilog`` for better help generation).
1406
Tim Peters21fbd572006-04-21 21:18:10 +00001407- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1408 called from a thread spawned as a side effect of importing a module.
1409
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001410- The pydoc module now supports documenting packages contained in
1411 .zip or .egg files.
1412
1413- The pkgutil module now has several new utility functions, such
1414 as ``walk_packages()`` to support working with packages that are either
1415 in the filesystem or zip files.
1416
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001417- The mailbox module can now modify and delete messages from
1418 mailboxes, in addition to simply reading them. Thanks to Gregory
1419 K. Johnson for writing the code, and to the 2005 Google Summer of
1420 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001421
Tim Petersc7605f22006-04-17 21:12:33 +00001422- The ``__del__`` method of class ``local`` in module ``_threading_local``
1423 returned before accomplishing any of its intended cleanup.
1424
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001425- Patch #790710: Add breakpoint command lists in pdb.
1426
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001427- Patch #1063914: Add Tkinter.Misc.clipboard_get().

1430
Anthony Baxtere29002c2006-04-12 12:07:31 +00001431- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1432 Windows. Bug #1469163.
1433
Phillip J. Eby47032112006-04-11 01:07:43 +00001434- The warnings, linecache, inspect, traceback, site, and doctest modules
1435 were updated to work correctly with modules imported from zipfiles or
1436 via other PEP 302 __loader__ objects.
1437
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001438- Patch #1467770: Reduce usage of subprocess._active to processes which
1439 the application hasn't waited on.

1450
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001451- The Makefile now has a reindent target, which runs reindent.py on
1452 the library.
1453
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001454- Patch #1470875: Building Python with MS Free Compiler

1459 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001460 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001461 CXX from --with-cxx-main, see description in README.
1462
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001463- Patch #1429775: Link extension modules with the shared libpython.

1466
Tim Peters8931ff12006-05-13 23:28:20 +00001467- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1468 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1469 and "%zu" for unsigned integers of type ``size_t``.
1470
Anthony Baxter51bcb682006-04-05 14:51:42 +00001471Tests
1472-----
1473
Nick Coghlanda2268f2006-04-24 04:37:15 +00001474- test_contextlib now checks contextlib.nested can cope with exceptions
1475 being raised and caught inside exit handlers.
1476
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001477- test_cmd_line now checks operation of the -m and -c command switches
1478
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001479- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1480 it separately and by hand. It also wasn't cleaning up its changes to
1481 the current Decimal context.
1482
Thomas Woutersabd08882006-04-26 15:53:30 +00001483- regrtest.py now has a -M option to run tests that test the new limits of
1484 containers, on 64-bit architectures. Running these tests is only sensible
1485 on 64-bit machines with more than two gigabytes of memory. The argument
1486 passed is the maximum amount of memory for the tests to use.

1513-----------------
1514
Nick Coghlan43832302006-04-23 17:04:07 +00001515- PEP 338: -m command line switch now delegates to runpy.run_module
1516 allowing it to support modules in packages and zipfiles
1517
Martin v. Löwisc661b882006-04-20 04:54:23 +00001518- On Windows, .DLL is not an accepted file name extension for
1519 extension modules anymore; extensions are only found if they
1520 end in .PYD.
1521
Martin v. Löwisea62d252006-04-03 10:56:49 +00001522- Bug #1421664: sys.stderr.encoding is now set to the same value as
1523 sys.stdout.encoding.
1524
Neal Norwitz92e212f2006-04-03 04:48:37 +00001525- __import__ accepts keyword arguments.
1526
Georg Brandlccadf842006-03-31 18:54:53 +00001527- Patch #1460496: round() now accepts keyword arguments.
1528
Anthony Baxter262c00a2006-03-30 10:53:17 +00001529- Fixed bug #1459029 - unicode reprs were double-escaped.
1530
Hye-Shik Changd478f342006-03-23 12:32:36 +00001531- Patch #1396919: The system scope threads are reenabled on FreeBSD
1532 5.4 and later versions.
1533
Neal Norwitze98ccf62006-03-23 05:39:47 +00001534- Bug #1115379: Compiling a Unicode string with an encoding declaration
1535 now gives a SyntaxError.
1536
Georg Brandlabd1ff82006-03-18 07:59:59 +00001537- Previously, Python code had no easy way to access the contents of a
1538 cell object. Now, a ``cell_contents`` attribute has been added
1539 (closes patch #1170323).
1540
Tim Peterscf79aac2006-03-16 01:14:46 +00001541- Patch #1123430: Python's small-object allocator now returns an arena to
1542 the system ``free()`` when all memory within an arena becomes unused
1543 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1544 freed. Some applications will see a drop in virtual memory size now,
1545 especially long-running applications that, from time to time, temporarily
1546 use a large number of small objects. Note that when Python returns an
1547 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001548 platform C library will in turn return that memory to the operating system.
1549 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001550 appears to be effective at least on Microsoft C and gcc-based systems.
1551 Thanks to Evan Jones for hard work and patience.
1552
Georg Brandl533ff6f2006-03-08 18:09:27 +00001553- Patch #1434038: property() now uses the getter's docstring if there is
1554 no "doc" argument given. This makes it possible to legitimately use
1555 property() as a decorator to produce a read-only property.
1556
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001557- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1558 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1559 of requiring an int or long in slicing and a few other contexts, enabling
1560 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1561
Neal Norwitz995acdf2006-03-07 05:01:00 +00001562- Fixed various bugs reported by Coverity's Prevent tool.
1563
Brett Cannonbf364092006-03-01 04:25:17 +00001564- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1565 new exception base class, BaseException, which has a new message attribute.
1566 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1567 Raising a string exception now raises a DeprecationWarning.
1568
Thomas Woutersfb609f42006-02-28 16:37:25 +00001569- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1570 explicitly relative, using 'from .module import name' to mean 'from the same
1571 package as this module is in. Imports without dots still default to the
1572 old relative-then-absolute, unless 'from __future__ import
1573 absolute_import' is used.
1574
Brett Cannona7446e32006-02-27 23:39:10 +00001575- Properly check if 'warnings' raises an exception (usually when a filter set
1576 to "error" is triggered) when raising a warning for raising string
1577 exceptions.
1578
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001579- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001580 The name was removed from Include/code.h.
1581
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001582- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001583
Guido van Rossum1968ad32006-02-25 22:38:04 +00001584- Patch 1433928:
1585 - The copy module now "copies" function objects (as atomic objects).
1586 - dict.__getitem__ now looks for a __missing__ hook before raising
1587 KeyError.
1588
Tim Peters84ef21c2006-02-28 20:39:06 +00001589- PEP 343: with statement implemented. Needs ``from __future__ import
1590 with_statement``. Use of 'with' as a variable will generate a warning.
1591 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001592 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001593 The following objects have __context__ methods:
1594 - The built-in file type.
1595 - The thread.LockType type.
1596 - The following types defined by the threading module:
1597 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1598 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001599
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001600- Fix the encodings package codec search function to only search
1601 inside its own package. Fixes problem reported in patch #1433198.
1602
1603 Note: Codec packages should implement and register their own
1604 codec search function. PEP 100 has the details.
1605
Tim Peters9ea89d22006-06-04 03:26:02 +00001606- PEP 353: Using ``Py_ssize_t`` as the index type.
1607
1608- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1609 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1610 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1611 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1612 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001613
Neal Norwitzfc76d632006-01-10 06:03:13 +00001614- Patch #1400181, fix unicode string formatting to not use the locale.
1615 This is how string objects work. u'%f' could use , instead of .
1616 for the decimal point. Now both strings and unicode always use periods.
1617
Neal Norwitz671b9e32006-01-09 07:07:12 +00001618- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1619 configure would break checking curses.h.
1620
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001621- Bug #959576: The pwd module is now builtin. This allows Python to be
1622 built on UNIX platforms without $HOME set.
1623
Neal Norwitzc10978f2005-12-19 06:07:16 +00001624- Bug #1072182, fix some potential problems if characters are signed.
1625
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001626- Bug #889500, fix line number on SyntaxWarning for global declarations.
1627
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001628- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1629
Neal Norwitze7214a12005-12-18 05:03:17 +00001630- Support for converting hex strings to floats no longer works.
1631 This was not portable. float('0x3') now raises a ValueError.
1632
Barry Warsaw2a38a862005-12-18 01:27:35 +00001633- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001634 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001635 is now displayed in interactive prompt banner.
1636
Georg Brandlfa166682005-12-17 21:45:17 +00001637- Implementation of PEP 341 - Unification of try/except and try/finally.
1638 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001639 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001640
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001641- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1642 now encodes backslash correctly.
1643
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001644- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1645
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001646- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001647 and long longs.
1648
Neal Norwitz67715f02005-11-09 06:59:35 +00001649- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001650 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001651 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001652
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001653- Replaced most Unicode charmap codecs with new ones using the
1654 new Unicode translate string feature in the builtin charmap
1655 codec; the codecs were created from the mapping tables available
1656 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1657 encodings now include a mapping for the Apple logo)
1658
Tim Peterse3547fd2005-12-16 23:13:57 +00001659- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001660
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001661- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001662
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001663- A new AST parser implementation was completed. The abstract
1664 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001665 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001666
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001667- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001668 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1669
Neal Norwitz708e51a2005-10-03 04:48:15 +00001670- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1671
Neal Norwitz11bd1192005-10-03 00:54:56 +00001672- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1673 Provide a warning when a directory is passed on the command line.
1674
Neal Norwitz40d37812005-10-02 01:48:49 +00001675- Fix segfault with invalid coding.
1676
1677- SF bug #772896: unknown encoding results in MemoryError.
1678
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001679- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001680 supported a __len__() method which evaluated to False when the iterator
1681 was empty.
1682
Guido van Rossum630db602005-09-20 18:49:54 +00001683- On 64-bit platforms, when __len__() returns a value that cannot be
1684 represented as a C int, raise OverflowError.
1685
Skip Montanarof8948ca2005-09-19 03:54:46 +00001686- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001687 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001688
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001689- SF bug #893549: parsing keyword arguments was broken with a few format
1690 codes.
1691
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001692- Changes donated by Elemental Security to make it work on AIX 5.3
1693 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1694 bug #105470: test_pwd fails on 64bit system (Opteron).
1695
Guido van Rossum539c6622005-09-14 17:49:54 +00001696- Changes donated by Elemental Security to make it work on HP-UX 11 on
1697 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1698
Georg Brandl4550b8d2005-08-26 06:43:52 +00001699- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001700 (fixes bug #1119418).
1701
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001702- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1703
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001704- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1705 exceptions that cause a function to exit.
1706
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001707- The implementation of set() and frozenset() was revised to use its
1708 own internal data structure. Memory consumption is reduced by 1/3
1709 and there are modest speed-ups as well. The API is unchanged.
1710
Tim Petersde7990b2005-07-17 23:45:23 +00001711- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1712
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001713- SF bug #1229429: PyObject_CallMethod failed to decrement some
1714 reference counts in some error exit cases.
1715
Tim Petersecc6e6a2005-07-10 22:30:55 +00001716- SF bug #1185883: Python's small-object memory allocator took over
1717 a block managed by the platform C library whenever a realloc specified
1718 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001719 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001720 portable way to copy data from the C-managed block into Python's
1721 small-object space without risking a memory fault. Python's small-object
1722 realloc now leaves such blocks under the control of the platform C
1723 realloc.
1724
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001725- SF bug #1232517: An overflow error was not detected properly when
1726 attempting to convert a large float to an int in os.utime().
1727
Raymond Hettinger3296e692005-06-29 23:29:56 +00001728- SF bug #1224347: hex longs now print with lowercase letters just
1729 like their int counterparts.
1730
Michael W. Hudson188d4362005-06-20 16:52:57 +00001731- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1732 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1733 interpreter states; back out that fix and do a better job (see
1734 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1735 for a longer write-up of the problem).
1736
Michael W. Hudsondf888462005-06-03 14:41:55 +00001737- SF patch #1180995: marshal now uses a binary format by default when
1738 serializing floats.
1739
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001740- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1741 the routines that promise to produce IEEE 754 binary representations
1742 of floats now simply copy bytes around.
1743
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001744- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1745 278.
1746
Brett Cannonc3647ac2005-04-26 03:45:26 +00001747- patch #1109424: int, long, float, complex, and unicode now check for the
1748 proper magic slot for type conversions when subclassed. Previously the
1749 magic slot was ignored during conversion. Semantics now match the way
1750 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001751 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001752 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001753 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001754
Barry Warsawc8d907c2005-04-19 23:43:40 +00001755- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1756 NULL, now raise an AttributeError when attempting to set or delete the
1757 attribute. Previously a TypeError was raised, but this was inconsistent
1758 with the equivalent pure-Python implementation.
1759
Michael W. Hudson774479c2005-04-18 08:46:17 +00001760- It is now safe to call PyGILState_Release() before
1761 PyEval_InitThreads() (note that if there is reason to believe there
1762 are multiple threads around you still must call PyEval_InitThreads()
1763 before using the Python API; this fix is for extension modules that
1764 have no way of knowing if Python is multi-threaded yet).
1765
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001766- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1767 disabled caused a crash.
1768
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001769- Bug #1165306: instancemethod_new allowed the creation of a method
1770 with im_class == im_self == NULL, which caused a crash when called.
1771
Tim Petersecc6e6a2005-07-10 22:30:55 +00001772- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001773 fixes the crash seen in bug #1165761
1774
Raymond Hettinger96229b12005-03-11 06:49:40 +00001775- Added two new builtins, any() and all().

Tim Petersf4e69282006-02-27 17:15:31 +00001817- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1818 current thread state when the auto-GIL-state machinery knows about
1819 it (since the thread state is being deleted, continuing to remember it
1820 can't help, but can hurt if another thread happens to get created with
1821 the same thread id).

2029 in attribute values.
2030
Anthony Baxterc51ee692006-04-01 00:57:31 +00002031- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002032 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002033 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002034 module will not be built.

Tim Petersc17976e2006-04-01 00:26:53 +00002036- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2037 aren't officially supported here, and trying to use them will probably

2059
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002060- email 4.0 package now integrated. This is largely the same as the email 3.0
2061 package that was included in Python 2.3, except that PEP 8 module names are
2062 now used (e.g. mail.message instead of email.Message). The MIME classes
2063 have been moved to a subpackage (e.g. email.mime.text instead of
2064 email.MIMEText). The old names are still supported for now. Several
2065 deprecated Message methods have been removed and lots of bugs have been
2066 fixed. More details can be found in the email package documentation.

2069 (a subclass of tuple) that provides incremental decoders and encoders
2070 (a way to use stateful codecs without the stream API). Python functions
2071 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2072 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2073 have been added.

2076 a ValueError instead of a StopIteration now (like file and cString.String do).
2077 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2078 called before (like file and StringIO.StringIO do).

Tim Peterse3547fd2005-12-16 23:13:57 +00002152 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2153 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2154 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2155 Ronald L. Rivest offered this advice for Python:
2156
2157 "The consensus of researchers in this area (at least as
2158 expressed at the NIST Hash Function Workshop 10/31/05),
2159 is that SHA-256 is a good choice for the time being, but
2160 that research should continue, and other alternatives may
2161 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002162

2319
Raymond Hettingerbab41432005-02-05 01:31:19 +00002320- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2321
Guido van Rossumd0641422005-02-03 15:01:24 +00002322- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2323 disables recursive traversal through instance attributes, which can
2324 be exploited in various ways.
2325
Tim Peterse3547fd2005-12-16 23:13:57 +00002326- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002327 flags on the HTTP listening socket.
2328
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002329- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2330 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2331
Fred Drakefbdeaad2006-07-29 16:56:15 +00002332- Patches #893642, #1039083: add allow_none, encoding arguments to
2333 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002334

2340
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002341- Enhancements to the csv module:
2342
2343 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002344 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002345 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002346 + Dialect parameter parsing has been re-implemented to improve error
2347 reporting.
2348 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2349 dictates.
2350 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002351 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002352 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002353 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2354 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002355 + reader now allows \r characters to be quoted (previously it only allowed
2356 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002357 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002358 + Dialect classes passed to the module are no longer instantiated by
2359 the module before being parsed (the former validation scheme required
2360 this, but the mechanism was unreliable).
2361 + The dialect registry now contains instances of the internal
2362 C-coded dialect type, rather than references to python objects.
2363 + the internal c-coded dialect type is now immutable.
2364 + register_dialect now accepts the same keyword dialect specifications
2365 as the reader and writer, allowing the user to register dialects
2366 without first creating a dialect class.
2367 + a configurable limit to the size of parsed fields has been added -
2368 previously, an unmatched quote character could result in the entire
2369 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002370 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002371 the parser field size limit (returning the former limit). The initial
2372 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002373 + A line_num attribute has been added to the reader object, which tracks
2374 the number of lines read from the source iterator. This is not
2375 the same as the number of records returned, as records can span
2376 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002377 + reader and writer objects were not being registered with the cyclic-GC.
2378 This has been fixed.
2379
Brett Cannone6539c42005-01-08 02:43:53 +00002380- _DummyThread objects in the threading module now delete self.__block that is
2381 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2382 lock primitives tend to be limited in number and thus should not be wasted on
2383 a _DummyThread object. Fixes bug #1089632.
2384
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002385- The imghdr module now detects Exif files.
2386
Raymond Hettinger6065d322004-12-20 23:51:53 +00002387- StringIO.truncate() now correctly adjusts the size attribute.
2388 (Bug #951915).
2389
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002390- locale.py now uses an updated locale alias table (built using
2391 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2392 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002393 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002394
Raymond Hettinger3557f422004-12-07 12:02:02 +00002395- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2396
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002397- the pickle module no longer accepts the deprecated None option in the
2398 args tuple returned by __reduce__().
2399
Brett Cannon84667c02004-12-07 03:25:18 +00002400- optparse now optionally imports gettext. This allows its use in setup.py.
2401
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002402- the pickle module no longer uses the deprecated bin parameter.
2403
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002404- the shelve module no longer uses the deprecated binary parameter.
2405
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002406- the pstats module no longer uses the deprecated ignore() method.
2407
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002408- the filecmp module no longer uses the deprecated use_statcache argument.
2409
Raymond Hettinger664347b2004-12-04 21:21:53 +00002410- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2411 extended or overridden by subclasses. Formerly, the subclassed method would
2412 be ignored by the rest of the module. (Bug #1078905).
2413
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002414- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002415 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002416
Walter Dörwald36733692004-12-22 12:50:50 +00002417- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2418 once when a size argument is given. This prevents a buffer overflow in the
2419 tokenizer with very long source lines.
2420
Barry Warsaw538561e2006-01-01 21:48:54 +00002421- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2422 immediately after creating the object, without any intervening
2423 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002424
Skip Montanaro05885812005-01-16 20:48:27 +00002425- The reconvert.quote function can now emit triple-quoted strings. The
2426 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002427
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002428- ``UserString.MutableString`` now supports negative indices in
2429 ``__setitem__`` and ``__delitem__``
2430
Greg Ward40407942005-03-05 02:53:17 +00002431- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2432 correctly.
2433
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002434- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2435 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2436 character even if the user has passed a size parameter to get a proper
2437 line ending. Remove the special handling of a "\r\n" that has been split
2438 between two lines.
2439
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002440- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2441 about illegal code points. The codec now supports PEP 293 style error
2442 handlers.
2443
Walter Dörwald78a78b02005-09-01 12:04:29 +00002444- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002445 from the input stream, so that the output is a byte string in the correct
2446 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002447
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002448- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2449 considering it exactly like a '*'.
2450
Walter Dörwald007f8df2005-10-09 19:42:27 +00002451- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2452 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002453
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002454- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2455
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002456- Patch #1413711: Certain patterns of differences were making difflib
2457 touch the recursion limit.
2458
Walter Dörwald58917a62006-03-31 15:26:22 +00002459- Bug #947906: An object oriented interface has been added to the calendar
2460 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002461 called as a script (e.g. via ``python -mcalendar``). Localized month and
2462 weekday names can be ouput (even if an exotic encoding is used) using
2463 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002464
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002465Build
2466-----
2467
Neal Norwitz602d3392006-03-31 08:21:40 +00002468- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2469 by using -mieee gcc option.
2470
Martin v. Löwis86d66262006-02-17 08:40:11 +00002471- Patch #1432345: Make python compile on DragonFly.
2472
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002473- Build support for Win64-AMD64 was added.
2474
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002475- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2476
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002477- Patch #881820: look for openpty and forkpty also in libbsd.
2478
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002479- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2480 The zlib module is now builtin on Windows.
2481
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002482- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2483
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002484- Bug #1189330: configure did not correctly determine the necessary
2485 value of LINKCC if python was built with GCC 4.0.
2486
Trent Mick8321b422005-07-26 02:29:21 +00002487- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2488 vulnerability in zlib 1.2.1 and 1.2.2.
2489
Brett Cannon08cd5982005-04-24 22:26:38 +00002490- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2491 flags that change binary compatibility. Changes were also made to
2492 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002493 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002494
Bob Ippolitoed233462005-03-29 13:47:59 +00002495- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2496 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2497 no longer exists). This configure patch makes things right.
2498
Martin v. Löwise2713be2005-03-08 15:03:08 +00002499- Bug #1158607: Build with --disable-unicode again.
2500
Brett Cannon46d96232005-02-16 00:07:19 +00002501- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2502 defined. Discovered as a result of not being able to build on OS X.
2503
Brett Cannon516592f2004-12-07 00:42:59 +00002504- setup.py now uses the directories specified in LDFLAGS using the -L option
2505 and in CPPFLAGS using the -I option for adding library and include
2506 directories, respectively, for compiling extension modules against. This has
2507 led to the core being compiled using the values in CPPFLAGS. It also removes
2508 the need for the special-casing of both DarwinPorts and Fink for darwin since
2509 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2510 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2511 Fink, ``-I/opt/local/include`` for DarwinPorts).
2512
Brett Cannon43802422005-02-10 20:48:03 +00002513- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2514 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2515 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2516 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002518C API
2519-----
2520
Tim Petersc9d78aa2006-03-26 23:27:58 +00002521- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2522 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2523 is obtained via the ``PyObject_`` family, it must be released via the
2524 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2525 always been officially true, but when Python's small-object allocator was
2526 introduced, an attempt was made to cater to a few extension modules
2527 discovered at the time that obtained memory via ``PyObject_New`` but
2528 released it via ``PyMem_DEL``. It's years later, and if such code still
2529 exists it will fail now (probably with segfaults, but calling wrong
2530 low-level memory management functions can yield many symptoms).
2531
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002532- Added a C API for set and frozenset objects.
2533
Raymond Hettinger66517482004-12-03 11:45:13 +00002534- Removed PyRange_New().
2535
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002536- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2537 mapping argument now. This string is used as a mapping table. Byte values
2538 greater than the length of the string and 0xFFFE are treated as undefined
2539 mappings.
