94
Brett Cannon9adeab72006-09-20 18:34:28 +000095- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This

97
Georg Brandlec6c2df2006-09-11 09:38:35 +000098- Make _PyGILState_NoteThreadState() static, it was not used anywhere

517=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000518
Anthony Baxterb4096662006-08-16 03:42:26 +0000519*Release date: 17-AUG-2006*

521Core and builtins
522-----------------
523
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000524- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000525 compared equal or unequal to a string and a UnicodeDecodeError
526 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000527
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000528 Instead, the equal (==) and unequal (!=) comparison operators will
529 now issue a UnicodeWarning and interpret the two objects as
530 unequal. The UnicodeWarning can be filtered as desired using
531 the warning framework, e.g. silenced completely, turned into an
532 exception, logged, etc.
533
534 Note that compare operators other than equal and unequal will still
535 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000536
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000537- Fix segfault when doing string formatting on subclasses of long.
538
539- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
540 with new-style classes.
541
542- Fix bug related to __len__ functions returning negative values with
543 classic classes.
544
545- Patch #1538606, Fix __index__() clipping. There were some problems
546 discovered with the API and how integers that didn't fit into Py_ssize_t
547 were handled. This patch attempts to provide enough alternatives
548 to effectively use __index__.
549
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000550- Bug #1536021: __hash__ may now return long int; the final hash
551 value is obtained by invoking hash on the long int.
552
Thomas Hellerab1049c2006-08-08 17:37:00 +0000553- Bug #1536786: buffer comparison could emit a RuntimeWarning.
554
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000555- Bug #1535165: fixed a segfault in input() and raw_input() when
556 sys.stdin is closed.
557
Thomas Heller74d36f02006-08-04 18:17:40 +0000558- On Windows, the PyErr_Warn function is now exported from
559 the Python dll again.
560
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000561- Bug #1191458: tracing over for loops now produces a line event
562 on each iteration. Fixing this problem required changing the .pyc
563 magic number. This means that .pyc files generated before 2.5c1
564 will be regenerated.
565
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000566- Bug #1333982: string/number constants were inappropriately stored
567 in the byte code and co_consts even if they were not used, ie
568 immediately popped off the stack.
569
Georg Brandle9462c72006-08-04 18:03:37 +0000570- Fixed a reference-counting problem in property().

573Library
574-------
575
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000576- Fix a bug in the ``compiler`` package that caused invalid code to be
577 generated for generator expressions.
578
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000579- The distutils version has been changed to 2.5.0. The change to
580 keep it programmatically in sync with the Python version running
581 the code (introduced in 2.5b3) has been reverted. It will continue
582 to be maintained manually as static string literal.
583
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000584- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000585 and this cannot be converted to the required C type, an exception is
586 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000587 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000588
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000589- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000590 an exception.
591
Tim Petersc10c9d02006-09-05 02:18:09 +0000592- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000593 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000594 workarounds for clocks with low resolution, to stop the code yielding
595 duplicate UUIDs.
596
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000597- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
598 before raising SystemExit, allowing IDLE to honor quit() and exit().
599
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000600- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
601
Georg Brandl7a1af772006-08-14 21:55:28 +0000602- Patch #1536071: trace.py should now find the full module name of a
603 file correctly even on Windows.
604
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000605- logging's atexit hook now runs even if the rest of the module has

627
Thomas Heller86720042006-08-14 11:17:48 +0000628- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
629 uses the _as_parameter_ attribute when objects are passed to foreign

Fred Drake53912162006-07-29 13:22:49 +0000679What's New in Python 2.5 beta 3?
680================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000681
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000682*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000683
684Core and builtins
685-----------------
686
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000687- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000688 returned a long (see PEP 353).
689
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000690- Bug #1515471: string.replace() accepts character buffers again.
691
Neal Norwitz07aadb12006-07-30 06:55:48 +0000692- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
693 This provides the proper warning for struct.pack().
694 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
695
Neal Norwitz0d62a062006-07-30 06:53:31 +0000696- Patch #1531113: Fix augmented assignment with yield expressions.
697 Also fix a SystemError when trying to assign to yield expressions.
698
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000699- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
700 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
701 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
702 excessive filesystem operations during imports.
703
Tim Petersbc24eee2006-07-27 01:14:53 +0000704- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
705 operations on signed longs that are formally undefined by C.
706 Unfortunately, at least one compiler now cares about that, so complicated
707 the code to make that compiler happy again.
708
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000709- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
710
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000711- Patch #1232023: Stop including current directory in search
712 path on Windows.
713
Neal Norwitze1fdb322006-07-21 05:32:28 +0000714- Fix some potential crashes found with failmalloc.
715
Neal Norwitze7563102006-07-17 01:00:16 +0000716- Fix warnings reported by Klocwork's static analysis tool.
717
Neal Norwitz84be93b2006-07-16 01:50:38 +0000718- Bug #1512814, Fix incorrect lineno's when code within a function
719 had more than 255 blank lines.
720
Georg Brandl9dceedb2006-07-12 15:31:17 +0000721- Patch #1521179: Python now accepts the standard options ``--help`` and
722 ``--version`` as well as ``/?`` on Windows.
723
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000724- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000725 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000726 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000727
Tim Peters112aad32006-07-19 00:03:19 +0000728- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000729 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000730 new ``sys._current_frames()`` returns a dictionary with one entry,
731 mapping the faux "thread id" 0 to the current frame.
732
Ronald Oussoren3075e162006-07-25 20:28:55 +0000733- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000734
Ronald Oussoren3075e162006-07-25 20:28:55 +0000735
Neal Norwitza1f10902006-07-12 07:28:29 +0000736Library
737-------
738
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000739- Correction of patch #1455898: In the mbcs decoder, set final=False
740 for stream decoder, but final=True for the decode function.
741
Georg Brandl07fec3a2006-08-01 18:49:24 +0000742- os.urandom no longer masks unrelated exceptions like SystemExit or
743 KeyboardInterrupt.
744
Tim Peters4643c2f2006-08-10 22:45:34 +0000745- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000746 shutil.copytree on Windows
747
Georg Brandle34ac7c2006-07-30 11:07:23 +0000748- Bug #1002398: The documentation for os.path.sameopenfile now correctly
749 refers to file descriptors, not file objects.
750
Tim Petersc10c9d02006-09-05 02:18:09 +0000751- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000752 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000753 #1513611, and probably others.
754
Georg Brandledd9b0d2006-07-29 09:33:26 +0000755- Bug #1441397: The compiler module now recognizes module and function
756 docstrings correctly as it did in Python 2.4.
757
Tim Peters6f681472006-07-27 23:44:37 +0000758- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
759 lost that tests are sorted by name before being run. This rarely
760 matters for well-written tests, but can create baffling symptoms if
761 side effects from one test to the next affect outcomes. ``DocTestFinder``
762 has been changed to sort the list of tests it returns.
763
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000764- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000765 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000766
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000767- Bug #978833: Really close underlying socket in _socketobject.close.
768
Georg Brandl8c036cc2006-08-20 13:15:39 +0000769- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
770 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000771
Georg Brandlcf0c1722006-07-26 07:23:32 +0000772- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
773 to recursive calls and call it with the failing package name.
774
Martin v. Löwis0b483032006-07-25 09:53:12 +0000775- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
776
Georg Brandlc13c34c2006-07-24 14:09:56 +0000777- Patch #1515343: Fix printing of deprecated string exceptions with a
778 value in the traceback module.
779
Greg Ward48fae7a2006-07-23 16:05:51 +0000780- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
781
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000782- Patch #1524429: Use repr() instead of backticks in Tkinter again.
783
Brett Cannoncaebe222006-07-18 04:41:36 +0000784- Bug #1520914: Change time.strftime() to accept a zero for any position in its
785 argument tuple. For arguments where zero is illegal, the value is forced to
786 the minimum value that is correct. This is to support an undocumented but
787 common way people used to fill in inconsequential information in the time
788 tuple pre-2.4.
789
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000790- Patch #1220874: Update the binhex module for Mach-O.
791
Barry Warsawb110bad2006-07-21 14:51:07 +0000792- The email package has improved RFC 2231 support, specifically for
793 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
794 (name*0=<blah>) parameter continuations. This may change the types of
795 values returned from email.message.Message.get_param() and friends.
796 Specifically in some cases where non-encoded continuations were used,
797 get_param() used to return a 3-tuple of (None, None, string) whereas now it
798 will just return the string (since non-encoded continuations don't have
799 charset and language parts).
800
801 Also, whereas % values were decoded in all parameter continuations, they are
802 now only decoded in encoded parameter parts.
803
Ronald Oussoren3075e162006-07-25 20:28:55 +0000804- Bug #1517990: IDLE keybindings on MacOS X now work correctly
805
806- Bug #1517996: IDLE now longer shows the default Tk menu when a
807 path browser, class browser or debugger is the frontmost window on MacOS X
808
Barry Warsaw00decd72006-07-27 23:43:15 +0000809- Patch #1520294: Support for getset and member descriptors in types.py,
810 inspect.py, and pydoc.py. Specifically, this allows for querying the type
811 of an object against these built-in types and more importantly, for getting
812 their docstrings printed in the interactive interpreter's help() function.

817
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000818- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
819 a socket operation on a socket with a timeout, the exception will be
820 caught correctly. Previously, the exception was not caught.
821
Thomas Heller1393d6a2006-07-28 21:43:20 +0000822- Patch #1529514: The _ctypes extension is now compiled on more
823 openbsd target platforms.
824
Tim Peters9cab5932006-07-28 00:30:00 +0000825- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
826 a memory leak, affecting pickles and deep copies.
827
Tim Petersbc24eee2006-07-27 01:14:53 +0000828- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000829 Paul Eggert.
830
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000831- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
832
Thomas Hellerce049a02006-07-14 17:51:14 +0000833- Patch #1521817: Index range checking on ctypes arrays containing
834 exactly one element enabled again. This allows iterating over these
835 arrays, without the need to check the array size before.
836
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000837- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000838 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000839 /dev/null in certain cases; this is now fixed.
840
Thomas Heller47d7a062006-07-12 08:43:47 +0000841- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
842 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000843
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000844- Because of a misspelled preprocessor symbol, ctypes was always
845 compiled without thread support; this is now fixed.
846
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000847- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
848 methods now allow their database parameter to be None as the
849 sleepycat API allows.
850
Matt Flemingec926502006-07-28 11:27:27 +0000851- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
852 bluetooth API compared with Linux and FreeBSD.
853
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000854Tests
855-----
856
857- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
858 how long the test file should take to play. Now accepts taking 2.93 secs
859 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
860
Georg Brandl4793aa32006-07-28 18:31:39 +0000861- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
862 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
863 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +0000870Mac
871---
872
873- PythonLauncher now works correctly when the path to the script contains
874 characters that are treated specially by the shell (such as quotes).
875
876- Bug #1527397: PythonLauncher now launches scripts with the working directory
877 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000878 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000879 expect.

889
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000890- Bug #1441486: The literal representation of -(sys.maxint - 1)
891 again evaluates to a int object, not a long.
892
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000893- Bug #1501934: The scope of global variables that are locally assigned
894 using augmented assignment is now correctly determined.
895
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000896- Bug #927248: Recursive method-wrapper objects can now safely

Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000902- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
903 omit a default "error" argument for NULL pointer. This allows
904 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000905
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000906- Bug #1519018: 'as' is now validated properly in import statements.
907
Neal Norwitz28746ab2006-07-09 22:14:42 +0000908- On 64 bit systems, int literals that use less than 64 bits are
909 now ints rather than longs.
910
Neal Norwitzed657552006-07-10 00:04:44 +0000911- Bug #1512814, Fix incorrect lineno's when code at module scope
912 started after line 256.
913
Tim Peters32a83612006-07-10 21:08:24 +0000914- New function ``sys._current_frames()`` returns a dict mapping thread
915 id to topmost thread stack frame. This is for expert use, and is
916 especially useful for debugging application deadlocks. The functionality
917 was previously available in Fazal Majid's ``threadframe`` extension
918 module, but it wasn't possible to do this in a wholly threadsafe way from
919 an extension.

966
Brett Cannon53ab5b72006-06-22 16:49:14 +0000967- Bug #1510580: The 'warnings' module improperly required that a Warning
968 category be either a types.ClassType and a subclass of Warning. The proper
969 check is just that it is a subclass with Warning as the documentation states.
970
Georg Brandlad29e632006-06-21 17:45:17 +0000971- The compiler module now correctly compiles the new try-except-finally
972 statement (bug #1509132).

984-----------------
985
Tim Peters112aad32006-07-19 00:03:19 +0000986- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
987 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
988 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000989
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000990- Assigning None to pointer type fields in ctypes structures possible
991 overwrote the wrong fields, this is fixed now.
992
993- Fixed a segfault in _ctypes when ctypes.wintypes were imported
994 on non-Windows platforms.
995
996- Bug #1518190: The ctypes.c_void_p constructor now accepts any
997 integer or long, without range checking.
998
999- Patch #1517790: It is now possible to use custom objects in the ctypes
1000 foreign function argtypes sequence as long as they provide a from_param
1001 method, no longer is it required that the object is a ctypes type.
1002
1003- The '_ctypes' extension module now works when Python is configured
1004 with the --without-threads option.
1005

Martin v. Löwisd73168d2006-07-14 09:58:55 +00001020- Automate Windows build process for the Win64 SSL module.
1021
Tim Peters32a83612006-07-10 21:08:24 +00001022- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001023 Previously, the slight difference could cause compilation errors of the
1024 'zlib' module on systems with more than one version of zlib.
1025
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001026- The MSI compileall step was fixed to also support a TARGETDIR

1057Core and builtins
1058-----------------
1059
Georg Brandla56b9152006-06-19 06:35:54 +00001060- Patch #1507676: Error messages returned by invalid abstract object operations
1061 (such as iterating over an integer) have been improved and now include the
1062 type of the offending object to help with debugging.
1063
Brett Cannonea3912b2006-06-13 21:46:41 +00001064- Bug #992017: A classic class that defined a __coerce__() method that returned
1065 its arguments swapped would infinitely recurse and segfault the interpreter.
1066
Neal Norwitz909eb122006-06-12 02:13:21 +00001067- Fix the socket tests so they can be run concurrently.
1068
Neal Norwitzb9845e72006-06-12 02:11:18 +00001069- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001070 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001071
Brett Cannon22565aa2006-06-09 22:31:23 +00001072- Bug #532646: object.__call__() will continue looking for the __call__
1073 attribute on objects until one without one is found. This leads to recursion
1074 when you take a class and set its __call__ attribute to an instance of the
1075 class. Originally fixed for classic classes, but this fix is for new-style.
1076 Removes the infinite_rec_3 crasher.
1077
Georg Brandl24250812006-06-09 18:45:48 +00001078- The string and unicode methods startswith() and endswith() now accept
1079 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1080
Brett Cannonde3b0522006-06-08 17:00:45 +00001081- Buffer objects, at the C level, never used the char buffer
1082 implementation even when the char buffer for the wrapped object was
1083 explicitly requested (originally returned the read or write buffer).
1084 Now a TypeError is raised if the char buffer is not present but is
1085 requested.
1086
Georg Brandlddbaa662006-06-04 21:56:52 +00001087- Patch #1346214: Statements like "if 0: suite" are now again optimized
1088 away like they were in Python 2.4.
1089
Georg Brandlb7c8f542006-05-27 12:30:25 +00001090- Builtin exceptions are now full-blown new-style classes instead of
1091 instances pretending to be classes, which speeds up exception handling
1092 by about 80% in comparison to 2.5a2.
1093
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001094- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1095 Unicode 4.1.
1096
Georg Brandlf4ef1162006-05-26 18:03:31 +00001097- Patch #921466: sys.path_importer_cache is now used to cache valid and
1098 invalid file paths for the built-in import machinery which leads to
1099 fewer open calls on startup.
1100
Tim Peters696cf432006-05-24 21:10:40 +00001101- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1102 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1103 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1104 the number of input digits (it was and remains linear-time for bases
1105 2, 4, 8, 16 and 32).
1106
Tim Petersb713ec22006-05-23 18:45:30 +00001107- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1108 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1109 an integer close to ``sys.maxint``. This was repaired by patch
1110 #1335972, which also gives a nice speedup.
1111
Richard Jonescebbefc2006-05-23 18:28:17 +00001112- Patch #1337051: reduced size of frame objects.
1113
1114- PyErr_NewException now accepts a tuple of base classes as its
1115 "base" parameter.
1116
Richard Jones7c88dcc2006-05-23 10:37:38 +00001117- Patch #876206: function call speedup by retaining allocated frame
1118 objects.
1119
Georg Brandl7b90e162006-05-18 07:01:27 +00001120- Bug #1462152: file() now checks more thoroughly for invalid mode
1121 strings and removes a possible "U" before passing the mode to the
1122 C library function.
1123
Neal Norwitz1004a532006-05-15 07:17:23 +00001124- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1125
Neal Norwitz373f0a72006-05-15 07:04:36 +00001126- Bug #1487966: Fix SystemError with conditional expression in assignment
1127
Martin v. Löwis879768d2006-05-11 13:28:43 +00001128- WindowsError now has two error code attributes: errno, which carries
1129 the error values from errno.h, and winerror, which carries the error
1130 values from winerror.h. Previous versions put the winerror.h values
1131 (from GetLastError()) into the errno attribute.
1132
Martin v. Löwis77736712006-05-04 05:51:03 +00001133- Patch #1475845: Raise IndentationError for unexpected indent.
1134
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001135- Patch #1479181: split open() and file() from being aliases for each other.
1136
Tim Peters44bd9862006-06-01 13:49:23 +00001137- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1138 methods were always silently ignored by dictionaries when comparing keys.
1139 They are now passed through (except when using the C API function
1140 ``PyDict_GetItem()``, whose semantics did not change).
1141
1142- Bug #1456209: In some obscure cases it was possible for a class with a
1143 custom ``__eq__()`` method to confuse dict internals when class instances
1144 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1145 No, you don't have any code that did this ;-)

1153
Brett Cannon6ee7d012006-06-08 16:23:04 +00001154- Change binascii.hexlify to accept a read-only buffer instead of only a char
1155 buffer and actually follow its documentation.
1156
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001157- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1158
Nick Coghlanc649ec52006-05-29 12:43:05 +00001159- Patch #1478788 (modified version): The functional extension module has
1160 been renamed to _functools and a functools Python wrapper module added.
1161 This provides a home for additional function related utilities that are
1162 not specifically about functional programming. See PEP 309.
1163
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001164- Patch #1493701: performance enhancements for struct module.

1169 copy() method.
1170
Andrew MacIntyre92913322006-06-13 15:04:24 +00001171- Patch #1454481: thread stack size is now tunable at runtime for thread
1172 enabled builds on Windows and systems with Posix threads support.
1173
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001174- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1175 (up to the system limit of 32K characters).
1176
1177- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1178 As a result, these functions now raise WindowsError instead of OSError.
1179
Tim Peters7a822da2006-05-25 21:50:17 +00001180- ``time.clock()`` on Win64 should use the high-performance Windows
1181 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1182 Windows platforms).
1183
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001184- Calling Tk_Init twice is refused if the first call failed as that
1185 may deadlock.
1186
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001187- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1188 accept it without potentially using an uninitialized pointer.
1189
1190- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1191 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

Gregory P. Smith3c228b12006-06-05 23:59:37 +00001200- bsddb: the __len__ method of a DB object has been fixed to return correct
1201 results. It could previously incorrectly return 0 in some cases.
1202 Fixes SF bug 1493322 (pybsddb bug 1184012).
1203
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001204- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1205 aborts the db transaction safely when a modifier callback fails.
1206 Fixes SF python patch/bug #1408584.
1207
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001208- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001209 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001210 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1211 database calls that would previously deadlock. [SF python bug #775414]

1242
Tim Peters43898b42006-06-14 04:09:25 +00001243- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1244 guarantee that adjacent triples in the return list always describe
1245 non-adjacent blocks. Previously, a pair of matching blocks could end
1246 up being described by multiple adjacent triples that formed a partition
1247 of the matching pair.

1256
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001257- The wsgiref package has been added to the standard library.
1258
Nick Coghlan676725d2006-06-08 13:54:49 +00001259- The functions update_wrapper() and wraps() have been added to the functools
1260 module. These make it easier to copy relevant metadata from the original
1261 function when writing wrapper functions.
1262
Tim Petersd6a9eef2006-06-05 01:48:21 +00001263- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1264 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001265
Martin v. Löwis3f767792006-06-04 19:36:28 +00001266- Patch #1359618: Speed up charmap encoder by using a trie structure
1267 for lookup.
1268
Tim Petersd609b1a2006-06-02 23:22:51 +00001269- The functions in the ``pprint`` module now sort dictionaries by key
1270 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1271 if and only if its display required more than one line, although that
1272 wasn't documented. The new behavior increases predictability; e.g.,
1273 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.

1300 a couple of issues, notably handling of long file names using the
1301 GNU LONGNAME extension.
1302
1303- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1304 new flag when ``name`` is already the name of an option flag.
1305
1306- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1307 package.

1347
1348*Release date: 27-APR-2006*

1350Core and builtins
1351-----------------
1352
Thomas Heller1b046642006-04-18 18:51:06 +00001353- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1354 by converting these apis from macros into exported functions again:
1355
1356 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1357 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1358 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1359 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1360 PyRun_String Py_CompileString
1361
Martin v. Löwis45294a92006-04-18 06:24:08 +00001362- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1363
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001364- All uses of PyStructSequence_InitType have been changed to initialize
1365 the type objects only once, even if the interpreter is initialized
1366 multiple times.
1367
Neal Norwitz61546162006-04-14 05:20:28 +00001368- Bug #1454485, array.array('u') could crash the interpreter. This was
1369 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1370 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1371
1372- Py_UNICODE is unsigned. It was always documented as unsigned, but
1373 due to a bug had a signed value in previous versions.
1374
Tim Peters3a5e8b12006-04-11 01:44:07 +00001375- Patch #837242: ``id()`` of any Python object always gives a positive
1376 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1377 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001378 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001379 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001380
Tim Peters3a5e8b12006-04-11 01:44:07 +00001381 def __hash__(self):
1382 return id(self) # WRONG
1383
1384 because a hash result must be a (short) Python int but it was always
1385 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001386 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001387 was always usable as a hash value before this patch. That's no longer
1388 necessarily so.
1389
1390- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001391 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001392 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001393 #1454844)
1394
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001395- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1396 involving generators that have paused outside of any ``try`` or ``with``
1397 blocks. (In 2.5a1, a paused generator that was part of a reference
1398 cycle could not be garbage collected, regardless of whether it was
1399 paused in a ``try`` or ``with`` block.)

1429 abusing errno.
1430
Tim Peters711bf302006-04-25 03:31:36 +00001431- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1432 a doctest to be skipped (the code is not run, and the expected output
1433 or exception is ignored).
1434
Nick Coghlanda2268f2006-04-24 04:37:15 +00001435- Fixed contextlib.nested to cope with exceptions being raised and
1436 caught inside exit handlers.
1437
Greg Wardab05edc2006-04-23 03:47:58 +00001438- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1439 hex, octal, or binary; add ``append_const`` action; keep going if
1440 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1441 added ``epilog`` for better help generation).
1442
Tim Peters21fbd572006-04-21 21:18:10 +00001443- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1444 called from a thread spawned as a side effect of importing a module.
1445
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001446- The pydoc module now supports documenting packages contained in
1447 .zip or .egg files.
1448
1449- The pkgutil module now has several new utility functions, such
1450 as ``walk_packages()`` to support working with packages that are either
1451 in the filesystem or zip files.
1452
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001453- The mailbox module can now modify and delete messages from
1454 mailboxes, in addition to simply reading them. Thanks to Gregory
1455 K. Johnson for writing the code, and to the 2005 Google Summer of
1456 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001457
Tim Petersc7605f22006-04-17 21:12:33 +00001458- The ``__del__`` method of class ``local`` in module ``_threading_local``
1459 returned before accomplishing any of its intended cleanup.
1460
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001461- Patch #790710: Add breakpoint command lists in pdb.

Tim Peters8931ff12006-05-13 23:28:20 +00001503- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1504 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1505 and "%zu" for unsigned integers of type ``size_t``.
1506

1508-----
1509
Nick Coghlanda2268f2006-04-24 04:37:15 +00001510- test_contextlib now checks contextlib.nested can cope with exceptions
1511 being raised and caught inside exit handlers.
1512
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001513- test_cmd_line now checks operation of the -m and -c command switches
1514
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001515- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1516 it separately and by hand. It also wasn't cleaning up its changes to
1517 the current Decimal context.
1518
Thomas Woutersabd08882006-04-26 15:53:30 +00001519- regrtest.py now has a -M option to run tests that test the new limits of
1520 containers, on 64-bit architectures. Running these tests is only sensible
1521 on 64-bit machines with more than two gigabytes of memory. The argument
1522 passed is the maximum amount of memory for the tests to use.
1523
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001524Tools

1526
1527- Added the Python benchmark suite pybench to the Tools/ directory;
1528 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001530Documentation
1531-------------
1532
Tim Petersb06d28c2006-05-12 01:57:59 +00001533- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1534
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001535- PEP 343: Added Context Types section to the library reference
1536 and attempted to bring other PEP 343 related documentation into
1537 line with the implementation and/or python-dev discussions.
1538
Tim Peters8dc73d22006-04-24 02:03:16 +00001539- Bug #1337990: clarified that ``doctest`` does not support examples
1540 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001543What's New in Python 2.5 alpha 1?
1544=================================
1545
Anthony Baxterebed3f62006-04-03 15:03:44 +00001546*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001547
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001548Core and builtins
1549-----------------
1550
Nick Coghlan43832302006-04-23 17:04:07 +00001551- PEP 338: -m command line switch now delegates to runpy.run_module
1552 allowing it to support modules in packages and zipfiles
1553
Martin v. Löwisc661b882006-04-20 04:54:23 +00001554- On Windows, .DLL is not an accepted file name extension for
1555 extension modules anymore; extensions are only found if they
1556 end in .PYD.
1557
Martin v. Löwisea62d252006-04-03 10:56:49 +00001558- Bug #1421664: sys.stderr.encoding is now set to the same value as
1559 sys.stdout.encoding.
1560
Neal Norwitz92e212f2006-04-03 04:48:37 +00001561- __import__ accepts keyword arguments.
1562
Georg Brandlccadf842006-03-31 18:54:53 +00001563- Patch #1460496: round() now accepts keyword arguments.
1564
Anthony Baxter262c00a2006-03-30 10:53:17 +00001565- Fixed bug #1459029 - unicode reprs were double-escaped.
1566
Hye-Shik Changd478f342006-03-23 12:32:36 +00001567- Patch #1396919: The system scope threads are reenabled on FreeBSD
1568 5.4 and later versions.
1569
Neal Norwitze98ccf62006-03-23 05:39:47 +00001570- Bug #1115379: Compiling a Unicode string with an encoding declaration
1571 now gives a SyntaxError.
1572
Georg Brandlabd1ff82006-03-18 07:59:59 +00001573- Previously, Python code had no easy way to access the contents of a
1574 cell object. Now, a ``cell_contents`` attribute has been added
1575 (closes patch #1170323).
1576
Tim Peterscf79aac2006-03-16 01:14:46 +00001577- Patch #1123430: Python's small-object allocator now returns an arena to
1578 the system ``free()`` when all memory within an arena becomes unused
1579 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1580 freed. Some applications will see a drop in virtual memory size now,
1581 especially long-running applications that, from time to time, temporarily
1582 use a large number of small objects. Note that when Python returns an
1583 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001584 platform C library will in turn return that memory to the operating system.
1585 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001586 appears to be effective at least on Microsoft C and gcc-based systems.
1587 Thanks to Evan Jones for hard work and patience.
1588
Georg Brandl533ff6f2006-03-08 18:09:27 +00001589- Patch #1434038: property() now uses the getter's docstring if there is
1590 no "doc" argument given. This makes it possible to legitimately use
1591 property() as a decorator to produce a read-only property.
1592
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001593- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1594 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1595 of requiring an int or long in slicing and a few other contexts, enabling
1596 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1597
Neal Norwitz995acdf2006-03-07 05:01:00 +00001598- Fixed various bugs reported by Coverity's Prevent tool.
1599
Brett Cannonbf364092006-03-01 04:25:17 +00001600- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1601 new exception base class, BaseException, which has a new message attribute.
1602 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1603 Raising a string exception now raises a DeprecationWarning.
1604
Thomas Woutersfb609f42006-02-28 16:37:25 +00001605- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1606 explicitly relative, using 'from .module import name' to mean 'from the same
1607 package as this module is in. Imports without dots still default to the
1608 old relative-then-absolute, unless 'from __future__ import
1609 absolute_import' is used.
1610
Brett Cannona7446e32006-02-27 23:39:10 +00001611- Properly check if 'warnings' raises an exception (usually when a filter set
1612 to "error" is triggered) when raising a warning for raising string
1613 exceptions.
1614
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001615- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001616 The name was removed from Include/code.h.
1617
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001618- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001619
Guido van Rossum1968ad32006-02-25 22:38:04 +00001620- Patch 1433928:
1621 - The copy module now "copies" function objects (as atomic objects).
1622 - dict.__getitem__ now looks for a __missing__ hook before raising
1623 KeyError.
1624
Tim Peters84ef21c2006-02-28 20:39:06 +00001625- PEP 343: with statement implemented. Needs ``from __future__ import
1626 with_statement``. Use of 'with' as a variable will generate a warning.
1627 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001628 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001629 The following objects have __context__ methods:
1630 - The built-in file type.
1631 - The thread.LockType type.
1632 - The following types defined by the threading module:
1633 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1634 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001635
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001636- Fix the encodings package codec search function to only search
1637 inside its own package. Fixes problem reported in patch #1433198.
1638
1639 Note: Codec packages should implement and register their own
1640 codec search function. PEP 100 has the details.
1641
Tim Peters9ea89d22006-06-04 03:26:02 +00001642- PEP 353: Using ``Py_ssize_t`` as the index type.
1643
1644- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1645 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1646 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1647 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1648 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001649
Neal Norwitzfc76d632006-01-10 06:03:13 +00001650- Patch #1400181, fix unicode string formatting to not use the locale.
1651 This is how string objects work. u'%f' could use , instead of .
1652 for the decimal point. Now both strings and unicode always use periods.
1653
Neal Norwitz671b9e32006-01-09 07:07:12 +00001654- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1655 configure would break checking curses.h.
1656
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001657- Bug #959576: The pwd module is now builtin. This allows Python to be
1658 built on UNIX platforms without $HOME set.
1659
Neal Norwitzc10978f2005-12-19 06:07:16 +00001660- Bug #1072182, fix some potential problems if characters are signed.
1661
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001662- Bug #889500, fix line number on SyntaxWarning for global declarations.
1663
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001664- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1665
Neal Norwitze7214a12005-12-18 05:03:17 +00001666- Support for converting hex strings to floats no longer works.
1667 This was not portable. float('0x3') now raises a ValueError.
1668
Barry Warsaw2a38a862005-12-18 01:27:35 +00001669- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001670 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001671 is now displayed in interactive prompt banner.
1672
Georg Brandlfa166682005-12-17 21:45:17 +00001673- Implementation of PEP 341 - Unification of try/except and try/finally.
1674 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001675 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001676
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001677- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1678 now encodes backslash correctly.
1679
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001680- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1681
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001682- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001683 and long longs.
1684
Neal Norwitz67715f02005-11-09 06:59:35 +00001685- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001686 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001687 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001688
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001689- Replaced most Unicode charmap codecs with new ones using the
1690 new Unicode translate string feature in the builtin charmap
1691 codec; the codecs were created from the mapping tables available
1692 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1693 encodings now include a mapping for the Apple logo)
1694
Tim Peterse3547fd2005-12-16 23:13:57 +00001695- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001696
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001697- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001698
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001699- A new AST parser implementation was completed. The abstract
1700 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001701 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001702
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001703- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001704 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1705
Neal Norwitz708e51a2005-10-03 04:48:15 +00001706- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1707
Neal Norwitz11bd1192005-10-03 00:54:56 +00001708- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1709 Provide a warning when a directory is passed on the command line.
1710
Neal Norwitz40d37812005-10-02 01:48:49 +00001711- Fix segfault with invalid coding.
1712
1713- SF bug #772896: unknown encoding results in MemoryError.
1714
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001715- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001716 supported a __len__() method which evaluated to False when the iterator
1717 was empty.
1718
Guido van Rossum630db602005-09-20 18:49:54 +00001719- On 64-bit platforms, when __len__() returns a value that cannot be
1720 represented as a C int, raise OverflowError.
1721
Skip Montanarof8948ca2005-09-19 03:54:46 +00001722- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001723 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001724
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001725- SF bug #893549: parsing keyword arguments was broken with a few format
1726 codes.
1727
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001728- Changes donated by Elemental Security to make it work on AIX 5.3
1729 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1730 bug #105470: test_pwd fails on 64bit system (Opteron).
1731
Guido van Rossum539c6622005-09-14 17:49:54 +00001732- Changes donated by Elemental Security to make it work on HP-UX 11 on
1733 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1734
Georg Brandl4550b8d2005-08-26 06:43:52 +00001735- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001736 (fixes bug #1119418).
1737
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001738- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1739
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001740- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1741 exceptions that cause a function to exit.
1742
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001743- The implementation of set() and frozenset() was revised to use its
1744 own internal data structure. Memory consumption is reduced by 1/3
1745 and there are modest speed-ups as well. The API is unchanged.
1746
Tim Petersde7990b2005-07-17 23:45:23 +00001747- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1748
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001749- SF bug #1229429: PyObject_CallMethod failed to decrement some
1750 reference counts in some error exit cases.
1751
Tim Petersecc6e6a2005-07-10 22:30:55 +00001752- SF bug #1185883: Python's small-object memory allocator took over
1753 a block managed by the platform C library whenever a realloc specified
1754 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001755 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001756 portable way to copy data from the C-managed block into Python's
1757 small-object space without risking a memory fault. Python's small-object
1758 realloc now leaves such blocks under the control of the platform C
1759 realloc.
1760
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001761- SF bug #1232517: An overflow error was not detected properly when
1762 attempting to convert a large float to an int in os.utime().
1763
Raymond Hettinger3296e692005-06-29 23:29:56 +00001764- SF bug #1224347: hex longs now print with lowercase letters just
1765 like their int counterparts.
1766
Michael W. Hudson188d4362005-06-20 16:52:57 +00001767- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1768 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1769 interpreter states; back out that fix and do a better job (see
1770 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1771 for a longer write-up of the problem).
1772
Michael W. Hudsondf888462005-06-03 14:41:55 +00001773- SF patch #1180995: marshal now uses a binary format by default when
1774 serializing floats.
1775
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001776- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1777 the routines that promise to produce IEEE 754 binary representations
1778 of floats now simply copy bytes around.
1779
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001780- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1781 278.
1782
Brett Cannonc3647ac2005-04-26 03:45:26 +00001783- patch #1109424: int, long, float, complex, and unicode now check for the
1784 proper magic slot for type conversions when subclassed. Previously the
1785 magic slot was ignored during conversion. Semantics now match the way
1786 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001787 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001788 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001789 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001790
Barry Warsawc8d907c2005-04-19 23:43:40 +00001791- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1792 NULL, now raise an AttributeError when attempting to set or delete the
1793 attribute. Previously a TypeError was raised, but this was inconsistent
1794 with the equivalent pure-Python implementation.
1795
Michael W. Hudson774479c2005-04-18 08:46:17 +00001796- It is now safe to call PyGILState_Release() before
1797 PyEval_InitThreads() (note that if there is reason to believe there
1798 are multiple threads around you still must call PyEval_InitThreads()
1799 before using the Python API; this fix is for extension modules that
1800 have no way of knowing if Python is multi-threaded yet).
1801
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001802- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1803 disabled caused a crash.
1804
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001805- Bug #1165306: instancemethod_new allowed the creation of a method
1806 with im_class == im_self == NULL, which caused a crash when called.
1807
Tim Petersecc6e6a2005-07-10 22:30:55 +00001808- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001809 fixes the crash seen in bug #1165761
1810
Raymond Hettinger96229b12005-03-11 06:49:40 +00001811- Added two new builtins, any() and all().
1812
Brett Cannon409d8f22005-03-05 06:47:57 +00001813- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001814 (e.g., ``class C(): pass`` is no longer a syntax error).
1815 Patch #1176012 added support to the 'parser' module and 'compiler' package
1816 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001817
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001818- Patch #1115086: Support PY_LONGLONG in structmember.
1819
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001820- Bug #1155938: new style classes did not check that __init__() was
1821 returning None.
1822
Tim Petersecc6e6a2005-07-10 22:30:55 +00001823- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001824 ('\') with a specific error message.
1825
Martin v. Löwisff232d72005-03-03 09:24:38 +00001826- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1827
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001828- Bug #1124295: the __name__ attribute of file objects was
1829 inadvertently made inaccessible in restricted mode.
1830
Tim Petersecc6e6a2005-07-10 22:30:55 +00001831- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001832 an ferror() call.
1833
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001834- min() and max() now support key= arguments with the same meaning as in
1835 list.sort().
1836
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001837- The peephole optimizer now performs simple constant folding in expressions:
1838 (2+3) --> (5).
1839
Raymond Hettingera422c342005-01-11 03:03:27 +00001840- set and frozenset objects can now be marshalled. SF #1098985.
1841
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001842- Bug #1077106: Poor argument checking could cause memory corruption
1843 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001844
Jeremy Hyltonab630502005-02-04 18:44:06 +00001845- The parser did not complain about future statements in illegal
1846 positions. It once again reports a syntax error if a future
1847 statement occurs after anything other than a doc string.
1848
Neil Schemenauercf52c072005-08-12 17:34:58 +00001849- Change the %s format specifier for str objects so that it returns a
1850 unicode instance if the argument is not an instance of basestring and
1851 calling __str__ on the argument returns a unicode instance.
1852
Tim Petersf4e69282006-02-27 17:15:31 +00001853- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1854 current thread state when the auto-GIL-state machinery knows about
1855 it (since the thread state is being deleted, continuing to remember it
1856 can't help, but can hurt if another thread happens to get created with
1857 the same thread id).
1858

1887 for applications that require this specific version (such as IDNA).
1888
Neal Norwitzb62c4332006-03-04 18:35:47 +00001889- The timing module is no longer built by default. It was deprecated

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002049- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2050 been renamed to have only a single underscore prefix. This was done to
2051 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002052
Nick Coghlan43832302006-04-23 17:04:07 +00002053- PEP 338: new module runpy defines a run_module function to support
2054 executing modules which provide access to source code or a code object
2055 via the PEP 302 import mechanisms.
2056
Anthony Baxter93f5b932006-04-03 08:05:07 +00002057- The email module's parsedate_tz function now sets the daylight savings

2065 in attribute values.
2066
Anthony Baxterc51ee692006-04-01 00:57:31 +00002067- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002068 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002069 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002070 module will not be built.
2071
Tim Petersc17976e2006-04-01 00:26:53 +00002072- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2073 aren't officially supported here, and trying to use them will probably
2074 raise an exception some day. But dicts have been allowed, and "mostly
2075 worked", so support for them won't go away without warning.
2076
Georg Brandl338ef7d2006-03-31 18:42:16 +00002077- Bug #1445068: getpass.getpass() can now be given an explicit stream

2095
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002096- email 4.0 package now integrated. This is largely the same as the email 3.0
2097 package that was included in Python 2.3, except that PEP 8 module names are
2098 now used (e.g. mail.message instead of email.Message). The MIME classes
2099 have been moved to a subpackage (e.g. email.mime.text instead of
2100 email.MIMEText). The old names are still supported for now. Several
2101 deprecated Message methods have been removed and lots of bugs have been
2102 fixed. More details can be found in the email package documentation.
2103
Walter Dörwald40108c92006-03-27 08:15:44 +00002104- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2105 (a subclass of tuple) that provides incremental decoders and encoders
2106 (a way to use stateful codecs without the stream API). Python functions
2107 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2108 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2109 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002110
Walter Dörwald067db482006-03-15 22:17:27 +00002111- Patch #1359365: Calling next() on a closed StringIO.String object raises
2112 a ValueError instead of a StopIteration now (like file and cString.String do).
2113 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2114 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002115

2189 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2190 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2191 Ronald L. Rivest offered this advice for Python:
2192
2193 "The consensus of researchers in this area (at least as
2194 expressed at the NIST Hash Function Workshop 10/31/05),
2195 is that SHA-256 is a good choice for the time being, but
2196 that research should continue, and other alternatives may
2197 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002198
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002199- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandl9166e1a2005-06-04 09:20:03 +00002299- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2300
Georg Brandl268e61c2005-06-03 14:28:50 +00002301- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2302 component of the path.
2303
Skip Montanaro174dd222005-05-14 20:54:16 +00002304- Patch #1120353: The xmlrpclib module provides better, more transparent,
2305 support for datetime.{datetime,date,time} objects. With use_datetime set
2306 to True, applications shouldn't have to fiddle with the DateTime wrapper
2307 class at all.
2308
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002309- distutils.commands.upload was added to support uploading distribution
2310 files to PyPI.
2311
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002312- distutils.commands.register now encodes the data as UTF-8 before posting
2313 them to PyPI.
2314
Raymond Hettinger267b8682005-03-27 10:47:39 +00002315- decimal operator and comparison methods now return NotImplemented
2316 instead of raising a TypeError when interacting with other types. This
2317 allows other classes to implement __radd__ style methods and have them
2318 work as expected.
2319
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002320- Bug #1163325: Decimal infinities failed to hash. Attempting to
2321 hash a NaN raised an InvalidOperation instead of a TypeError.
2322
Tim Petersecc6e6a2005-07-10 22:30:55 +00002323- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002324 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2325
Martin v. Löwis00a73e72005-03-04 19:40:34 +00002326- Patch #1043890: Add extractall method to tarfile.

Martin v. Löwisc72dd382005-03-04 13:50:17 +00002328- Patch #1075887: Don't require MSVC in distutils if there is nothing
2329 to build.
2330
Martin v. Löwis637431b2005-03-03 23:12:42 +00002331- Patch #1103407: Properly deal with tarfile iterators when untarring
2332 symbolic links on Windows.
2333
Tim Petersecc6e6a2005-07-10 22:30:55 +00002334- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +00002335 profile.py if available.
2336
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00002337- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
2338
Martin v. Löwisc5574e82005-03-03 10:57:37 +00002339- Patch #1117454: Remove code to special-case cookies without values
2340 in LWPCookieJar.
2341
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00002342- Patch #1117339: Add cookielib special name tests.
2343

2345
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00002346- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
2347
Martin v. Löwisdf241532005-03-03 08:17:42 +00002348- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
2349
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00002350- Patch #1104111: Alter setup.py --help and --help-commands.
2351
Martin v. Löwis4afe1542005-03-01 08:09:28 +00002352- Patch #1121234: Properly cleanup _exit and tkerror commands.
2353
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00002354- Patch #1049151: xdrlib now unpacks booleans as True or False.
2355
Raymond Hettingerbab41432005-02-05 01:31:19 +00002356- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2357
Guido van Rossumd0641422005-02-03 15:01:24 +00002358- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2359 disables recursive traversal through instance attributes, which can
2360 be exploited in various ways.
2361
Tim Peterse3547fd2005-12-16 23:13:57 +00002362- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002363 flags on the HTTP listening socket.
2364
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002365- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2366 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2367
Fred Drakefbdeaad2006-07-29 16:56:15 +00002368- Patches #893642, #1039083: add allow_none, encoding arguments to
2369 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002370
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002371- Bug #1110478: Revert os.environ.update to do putenv again.
2372
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002373- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2374
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002375- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2376
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002377- Enhancements to the csv module:
2378
2379 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002380 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002381 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002382 + Dialect parameter parsing has been re-implemented to improve error
2383 reporting.
2384 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2385 dictates.
2386 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002387 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002388 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002389 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2390 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002391 + reader now allows \r characters to be quoted (previously it only allowed
2392 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002393 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002394 + Dialect classes passed to the module are no longer instantiated by
2395 the module before being parsed (the former validation scheme required
2396 this, but the mechanism was unreliable).
2397 + The dialect registry now contains instances of the internal
2398 C-coded dialect type, rather than references to python objects.
2399 + the internal c-coded dialect type is now immutable.
2400 + register_dialect now accepts the same keyword dialect specifications
2401 as the reader and writer, allowing the user to register dialects
2402 without first creating a dialect class.
2403 + a configurable limit to the size of parsed fields has been added -
2404 previously, an unmatched quote character could result in the entire
2405 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002406 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002407 the parser field size limit (returning the former limit). The initial
2408 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002409 + A line_num attribute has been added to the reader object, which tracks
2410 the number of lines read from the source iterator. This is not
2411 the same as the number of records returned, as records can span
2412 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002413 + reader and writer objects were not being registered with the cyclic-GC.
2414 This has been fixed.
2415
Brett Cannone6539c42005-01-08 02:43:53 +00002416- _DummyThread objects in the threading module now delete self.__block that is
2417 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2418 lock primitives tend to be limited in number and thus should not be wasted on
2419 a _DummyThread object. Fixes bug #1089632.
2420
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002421- The imghdr module now detects Exif files.
2422
Raymond Hettinger6065d322004-12-20 23:51:53 +00002423- StringIO.truncate() now correctly adjusts the size attribute.
2424 (Bug #951915).
2425
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002426- locale.py now uses an updated locale alias table (built using
2427 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2428 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002429 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002430
Raymond Hettinger3557f422004-12-07 12:02:02 +00002431- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2432
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002433- the pickle module no longer accepts the deprecated None option in the
2434 args tuple returned by __reduce__().
2435
Brett Cannon84667c02004-12-07 03:25:18 +00002436- optparse now optionally imports gettext. This allows its use in setup.py.
2437
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002438- the pickle module no longer uses the deprecated bin parameter.
2439
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002440- the shelve module no longer uses the deprecated binary parameter.
2441
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002442- the pstats module no longer uses the deprecated ignore() method.
2443
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002444- the filecmp module no longer uses the deprecated use_statcache argument.
2445
Raymond Hettinger664347b2004-12-04 21:21:53 +00002446- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2447 extended or overridden by subclasses. Formerly, the subclassed method would
2448 be ignored by the rest of the module. (Bug #1078905).
2449
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002450- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002451 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002452
Walter Dörwald36733692004-12-22 12:50:50 +00002453- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2454 once when a size argument is given. This prevents a buffer overflow in the
2455 tokenizer with very long source lines.
2456
Barry Warsaw538561e2006-01-01 21:48:54 +00002457- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2458 immediately after creating the object, without any intervening
2459 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002460
Skip Montanaro05885812005-01-16 20:48:27 +00002461- The reconvert.quote function can now emit triple-quoted strings. The
2462 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002463
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002464- ``UserString.MutableString`` now supports negative indices in
2465 ``__setitem__`` and ``__delitem__``
2466
Greg Ward40407942005-03-05 02:53:17 +00002467- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2468 correctly.
2469
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002470- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2471 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2472 character even if the user has passed a size parameter to get a proper
2473 line ending. Remove the special handling of a "\r\n" that has been split
2474 between two lines.
2475
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002476- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2477 about illegal code points. The codec now supports PEP 293 style error
2478 handlers.
2479
Walter Dörwald78a78b02005-09-01 12:04:29 +00002480- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002481 from the input stream, so that the output is a byte string in the correct
2482 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002483
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002484- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2485 considering it exactly like a '*'.
2486
Walter Dörwald007f8df2005-10-09 19:42:27 +00002487- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2488 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002489
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002490- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2491
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002492- Patch #1413711: Certain patterns of differences were making difflib
2493 touch the recursion limit.
2494
Walter Dörwald58917a62006-03-31 15:26:22 +00002495- Bug #947906: An object oriented interface has been added to the calendar
2496 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002497 called as a script (e.g. via ``python -mcalendar``). Localized month and
2498 weekday names can be ouput (even if an exotic encoding is used) using
2499 special classes that use unicode.

2502-----
2503
Neal Norwitz602d3392006-03-31 08:21:40 +00002504- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2505 by using -mieee gcc option.
2506
Martin v. Löwis86d66262006-02-17 08:40:11 +00002507- Patch #1432345: Make python compile on DragonFly.
2508
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002509- Build support for Win64-AMD64 was added.
2510
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002511- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2512
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002513- Patch #881820: look for openpty and forkpty also in libbsd.
2514
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002515- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2516 The zlib module is now builtin on Windows.
2517
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002518- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2519
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002520- Bug #1189330: configure did not correctly determine the necessary
2521 value of LINKCC if python was built with GCC 4.0.
2522
Trent Mick8321b422005-07-26 02:29:21 +00002523- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2524 vulnerability in zlib 1.2.1 and 1.2.2.
2525
Brett Cannon08cd5982005-04-24 22:26:38 +00002526- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2527 flags that change binary compatibility. Changes were also made to
2528 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002529 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002530
Bob Ippolitoed233462005-03-29 13:47:59 +00002531- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2532 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2533 no longer exists). This configure patch makes things right.
2534
Martin v. Löwise2713be2005-03-08 15:03:08 +00002535- Bug #1158607: Build with --disable-unicode again.
2536
Brett Cannon46d96232005-02-16 00:07:19 +00002537- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2538 defined. Discovered as a result of not being able to build on OS X.
2539
Brett Cannon516592f2004-12-07 00:42:59 +00002540- setup.py now uses the directories specified in LDFLAGS using the -L option
2541 and in CPPFLAGS using the -I option for adding library and include
2542 directories, respectively, for compiling extension modules against. This has
2543 led to the core being compiled using the values in CPPFLAGS. It also removes
2544 the need for the special-casing of both DarwinPorts and Fink for darwin since
2545 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2546 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2547 Fink, ``-I/opt/local/include`` for DarwinPorts).
2548
Brett Cannon43802422005-02-10 20:48:03 +00002549- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2550 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2551 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2552 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002554C API
2555-----
2556
Tim Petersc9d78aa2006-03-26 23:27:58 +00002557- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2558 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2559 is obtained via the ``PyObject_`` family, it must be released via the
2560 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2561 always been officially true, but when Python's small-object allocator was
2562 introduced, an attempt was made to cater to a few extension modules
2563 discovered at the time that obtained memory via ``PyObject_New`` but
2564 released it via ``PyMem_DEL``. It's years later, and if such code still
