310
Georg Brandl2c94bf72006-09-24 10:36:01 +0000311- Make webbrowser.BackgroundBrowser usable in Windows (it wasn't because

396 mode by only placing a timeout on the select() if an input hook has
397 been defined. This prevents an interactive Python from waking up 10

408 variables.
409
Brett Cannon6d9520c2006-12-13 23:09:53 +0000410- Added guard_warnings_filter to test.test_support. It returns a context

509=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000510
Anthony Baxterb4096662006-08-16 03:42:26 +0000511*Release date: 17-AUG-2006*

513Core and builtins
514-----------------
515
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000516- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000517 compared equal or unequal to a string and a UnicodeDecodeError
518 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000519
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000520 Instead, the equal (==) and unequal (!=) comparison operators will
521 now issue a UnicodeWarning and interpret the two objects as
522 unequal. The UnicodeWarning can be filtered as desired using
523 the warning framework, e.g. silenced completely, turned into an
524 exception, logged, etc.
525
526 Note that compare operators other than equal and unequal will still
527 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000528
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000529- Fix segfault when doing string formatting on subclasses of long.
530
531- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
532 with new-style classes.
533
534- Fix bug related to __len__ functions returning negative values with
535 classic classes.
536
537- Patch #1538606, Fix __index__() clipping. There were some problems
538 discovered with the API and how integers that didn't fit into Py_ssize_t
539 were handled. This patch attempts to provide enough alternatives
540 to effectively use __index__.
541
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000542- Bug #1536021: __hash__ may now return long int; the final hash
543 value is obtained by invoking hash on the long int.
544
Thomas Hellerab1049c2006-08-08 17:37:00 +0000545- Bug #1536786: buffer comparison could emit a RuntimeWarning.
546
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000547- Bug #1535165: fixed a segfault in input() and raw_input() when
548 sys.stdin is closed.
549
Thomas Heller74d36f02006-08-04 18:17:40 +0000550- On Windows, the PyErr_Warn function is now exported from
551 the Python dll again.
552
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000553- Bug #1191458: tracing over for loops now produces a line event
554 on each iteration. Fixing this problem required changing the .pyc
555 magic number. This means that .pyc files generated before 2.5c1
556 will be regenerated.
557
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000558- Bug #1333982: string/number constants were inappropriately stored
559 in the byte code and co_consts even if they were not used, ie
560 immediately popped off the stack.
561
Georg Brandle9462c72006-08-04 18:03:37 +0000562- Fixed a reference-counting problem in property().

565Library
566-------
567
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000568- Fix a bug in the ``compiler`` package that caused invalid code to be
569 generated for generator expressions.
570
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000571- The distutils version has been changed to 2.5.0. The change to
572 keep it programmatically in sync with the Python version running
573 the code (introduced in 2.5b3) has been reverted. It will continue
574 to be maintained manually as static string literal.
575
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000576- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000577 and this cannot be converted to the required C type, an exception is
578 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000579 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000580
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000581- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000582 an exception.
583
Tim Petersc10c9d02006-09-05 02:18:09 +0000584- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000585 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000586 workarounds for clocks with low resolution, to stop the code yielding
587 duplicate UUIDs.
588
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000589- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
590 before raising SystemExit, allowing IDLE to honor quit() and exit().
591
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000592- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
593
Georg Brandl7a1af772006-08-14 21:55:28 +0000594- Patch #1536071: trace.py should now find the full module name of a
595 file correctly even on Windows.
596
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000597- logging's atexit hook now runs even if the rest of the module has
598 already been cleaned up.
599
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000600- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000601
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000602- Bug #1531405, format_exception no longer raises an exception if

619
Thomas Heller86720042006-08-14 11:17:48 +0000620- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
621 uses the _as_parameter_ attribute when objects are passed to foreign

623
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000624- Bug #1530559, struct.pack raises TypeError where it used to convert.

641
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000642

650-----
651
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +0000652- Bug #1535502, build _hashlib on Windows, and use masm assembler
653 code in OpenSSL.
654
Thomas Hellerdb7b4432006-08-04 19:49:31 +0000655- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

Fred Drake53912162006-07-29 13:22:49 +0000671What's New in Python 2.5 beta 3?
672================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000673
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000674*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000675
676Core and builtins
677-----------------
678
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000679- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000680 returned a long (see PEP 353).
681
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000682- Bug #1515471: string.replace() accepts character buffers again.
683
Neal Norwitz07aadb12006-07-30 06:55:48 +0000684- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
685 This provides the proper warning for struct.pack().
686 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
687
Neal Norwitz0d62a062006-07-30 06:53:31 +0000688- Patch #1531113: Fix augmented assignment with yield expressions.
689 Also fix a SystemError when trying to assign to yield expressions.
690
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000691- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
692 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
693 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
694 excessive filesystem operations during imports.
695
Tim Petersbc24eee2006-07-27 01:14:53 +0000696- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
697 operations on signed longs that are formally undefined by C.
698 Unfortunately, at least one compiler now cares about that, so complicated
699 the code to make that compiler happy again.
700
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000701- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
702
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000703- Patch #1232023: Stop including current directory in search
704 path on Windows.
705
Neal Norwitze1fdb322006-07-21 05:32:28 +0000706- Fix some potential crashes found with failmalloc.
707
Neal Norwitze7563102006-07-17 01:00:16 +0000708- Fix warnings reported by Klocwork's static analysis tool.
709
Neal Norwitz84be93b2006-07-16 01:50:38 +0000710- Bug #1512814, Fix incorrect lineno's when code within a function
711 had more than 255 blank lines.
712
Georg Brandl9dceedb2006-07-12 15:31:17 +0000713- Patch #1521179: Python now accepts the standard options ``--help`` and
714 ``--version`` as well as ``/?`` on Windows.
715
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000716- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000717 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000718 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000719
Tim Peters112aad32006-07-19 00:03:19 +0000720- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000721 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000722 new ``sys._current_frames()`` returns a dictionary with one entry,
723 mapping the faux "thread id" 0 to the current frame.
724
Ronald Oussoren3075e162006-07-25 20:28:55 +0000725- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000726
Ronald Oussoren3075e162006-07-25 20:28:55 +0000727
Neal Norwitza1f10902006-07-12 07:28:29 +0000728Library
729-------
730
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000731- Correction of patch #1455898: In the mbcs decoder, set final=False
732 for stream decoder, but final=True for the decode function.
733
Georg Brandl07fec3a2006-08-01 18:49:24 +0000734- os.urandom no longer masks unrelated exceptions like SystemExit or
735 KeyboardInterrupt.
736
Tim Peters4643c2f2006-08-10 22:45:34 +0000737- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000738 shutil.copytree on Windows
739
Georg Brandle34ac7c2006-07-30 11:07:23 +0000740- Bug #1002398: The documentation for os.path.sameopenfile now correctly
741 refers to file descriptors, not file objects.
742
Tim Petersc10c9d02006-09-05 02:18:09 +0000743- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000744 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000745 #1513611, and probably others.
746
Georg Brandledd9b0d2006-07-29 09:33:26 +0000747- Bug #1441397: The compiler module now recognizes module and function
748 docstrings correctly as it did in Python 2.4.
749
Tim Peters6f681472006-07-27 23:44:37 +0000750- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
751 lost that tests are sorted by name before being run. This rarely
752 matters for well-written tests, but can create baffling symptoms if
753 side effects from one test to the next affect outcomes. ``DocTestFinder``
754 has been changed to sort the list of tests it returns.
755
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000756- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000757 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000758
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000759- Bug #978833: Really close underlying socket in _socketobject.close.
760
Georg Brandl8c036cc2006-08-20 13:15:39 +0000761- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
762 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000763
Georg Brandlcf0c1722006-07-26 07:23:32 +0000764- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
765 to recursive calls and call it with the failing package name.
766
Martin v. Löwis0b483032006-07-25 09:53:12 +0000767- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
768
Georg Brandlc13c34c2006-07-24 14:09:56 +0000769- Patch #1515343: Fix printing of deprecated string exceptions with a
770 value in the traceback module.
771
Greg Ward48fae7a2006-07-23 16:05:51 +0000772- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
773
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000774- Patch #1524429: Use repr() instead of backticks in Tkinter again.
775
Brett Cannoncaebe222006-07-18 04:41:36 +0000776- Bug #1520914: Change time.strftime() to accept a zero for any position in its
777 argument tuple. For arguments where zero is illegal, the value is forced to
778 the minimum value that is correct. This is to support an undocumented but
779 common way people used to fill in inconsequential information in the time
780 tuple pre-2.4.
781
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000782- Patch #1220874: Update the binhex module for Mach-O.
783
Barry Warsawb110bad2006-07-21 14:51:07 +0000784- The email package has improved RFC 2231 support, specifically for
785 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
786 (name*0=<blah>) parameter continuations. This may change the types of
787 values returned from email.message.Message.get_param() and friends.
788 Specifically in some cases where non-encoded continuations were used,
789 get_param() used to return a 3-tuple of (None, None, string) whereas now it
790 will just return the string (since non-encoded continuations don't have
791 charset and language parts).
792
793 Also, whereas % values were decoded in all parameter continuations, they are
794 now only decoded in encoded parameter parts.
795
Ronald Oussoren3075e162006-07-25 20:28:55 +0000796- Bug #1517990: IDLE keybindings on MacOS X now work correctly
797
798- Bug #1517996: IDLE now longer shows the default Tk menu when a
799 path browser, class browser or debugger is the frontmost window on MacOS X
800
Barry Warsaw00decd72006-07-27 23:43:15 +0000801- Patch #1520294: Support for getset and member descriptors in types.py,
802 inspect.py, and pydoc.py. Specifically, this allows for querying the type
803 of an object against these built-in types and more importantly, for getting
804 their docstrings printed in the interactive interpreter's help() function.

809
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000810- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
811 a socket operation on a socket with a timeout, the exception will be
812 caught correctly. Previously, the exception was not caught.
813
Thomas Heller1393d6a2006-07-28 21:43:20 +0000814- Patch #1529514: The _ctypes extension is now compiled on more
815 openbsd target platforms.
816
Tim Peters9cab5932006-07-28 00:30:00 +0000817- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
818 a memory leak, affecting pickles and deep copies.
819
Tim Petersbc24eee2006-07-27 01:14:53 +0000820- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000821 Paul Eggert.
822
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000823- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
824
Thomas Hellerce049a02006-07-14 17:51:14 +0000825- Patch #1521817: Index range checking on ctypes arrays containing
826 exactly one element enabled again. This allows iterating over these
827 arrays, without the need to check the array size before.
828
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000829- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000830 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000831 /dev/null in certain cases; this is now fixed.
832
Thomas Heller47d7a062006-07-12 08:43:47 +0000833- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
834 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000835
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000836- Because of a misspelled preprocessor symbol, ctypes was always
837 compiled without thread support; this is now fixed.
838
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000839- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
840 methods now allow their database parameter to be None as the
841 sleepycat API allows.
842
Matt Flemingec926502006-07-28 11:27:27 +0000843- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
844 bluetooth API compared with Linux and FreeBSD.
845
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000846Tests
847-----
848
849- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
850 how long the test file should take to play. Now accepts taking 2.93 secs
851 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
852
Georg Brandl4793aa32006-07-28 18:31:39 +0000853- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
854 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
855 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +0000862Mac
863---
864
865- PythonLauncher now works correctly when the path to the script contains
866 characters that are treated specially by the shell (such as quotes).
867
868- Bug #1527397: PythonLauncher now launches scripts with the working directory
869 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000870 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000871 expect.

883 again evaluates to a int object, not a long.
884
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000885- Bug #1501934: The scope of global variables that are locally assigned

Neal Norwitz28746ab2006-07-09 22:14:42 +0000900- On 64 bit systems, int literals that use less than 64 bits are
901 now ints rather than longs.
902
Neal Norwitzed657552006-07-10 00:04:44 +0000903- Bug #1512814, Fix incorrect lineno's when code at module scope
904 started after line 256.
905
Tim Peters32a83612006-07-10 21:08:24 +0000906- New function ``sys._current_frames()`` returns a dict mapping thread
907 id to topmost thread stack frame. This is for expert use, and is
908 especially useful for debugging application deadlocks. The functionality
909 was previously available in Fazal Majid's ``threadframe`` extension
910 module, but it wasn't possible to do this in a wholly threadsafe way from
911 an extension.

931 be treated as the value they contain, instead.
932
Martin v. Löwisede77f52006-07-03 13:01:35 +0000933- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

958
Brett Cannon53ab5b72006-06-22 16:49:14 +0000959- Bug #1510580: The 'warnings' module improperly required that a Warning
960 category be either a types.ClassType and a subclass of Warning. The proper
961 check is just that it is a subclass with Warning as the documentation states.
962
Georg Brandlad29e632006-06-21 17:45:17 +0000963- The compiler module now correctly compiles the new try-except-finally
964 statement (bug #1509132).

976-----------------
977
Tim Peters112aad32006-07-19 00:03:19 +0000978- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
979 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
980 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000981
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000982- Assigning None to pointer type fields in ctypes structures possible
983 overwrote the wrong fields, this is fixed now.
984
985- Fixed a segfault in _ctypes when ctypes.wintypes were imported
986 on non-Windows platforms.
987
988- Bug #1518190: The ctypes.c_void_p constructor now accepts any
989 integer or long, without range checking.
990
991- Patch #1517790: It is now possible to use custom objects in the ctypes
992 foreign function argtypes sequence as long as they provide a from_param
993 method, no longer is it required that the object is a ctypes type.
994
995- The '_ctypes' extension module now works when Python is configured
996 with the --without-threads option.

1013
Tim Peters32a83612006-07-10 21:08:24 +00001014- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001015 Previously, the slight difference could cause compilation errors of the
1016 'zlib' module on systems with more than one version of zlib.
1017
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001018- The MSI compileall step was fixed to also support a TARGETDIR

1049Core and builtins
1050-----------------
1051
Georg Brandla56b9152006-06-19 06:35:54 +00001052- Patch #1507676: Error messages returned by invalid abstract object operations
1053 (such as iterating over an integer) have been improved and now include the
1054 type of the offending object to help with debugging.
1055
Brett Cannonea3912b2006-06-13 21:46:41 +00001056- Bug #992017: A classic class that defined a __coerce__() method that returned
1057 its arguments swapped would infinitely recurse and segfault the interpreter.
1058
Neal Norwitz909eb122006-06-12 02:13:21 +00001059- Fix the socket tests so they can be run concurrently.
1060
Neal Norwitzb9845e72006-06-12 02:11:18 +00001061- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001062 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001063
Brett Cannon22565aa2006-06-09 22:31:23 +00001064- Bug #532646: object.__call__() will continue looking for the __call__
1065 attribute on objects until one without one is found. This leads to recursion
1066 when you take a class and set its __call__ attribute to an instance of the
1067 class. Originally fixed for classic classes, but this fix is for new-style.
1068 Removes the infinite_rec_3 crasher.
1069
Georg Brandl24250812006-06-09 18:45:48 +00001070- The string and unicode methods startswith() and endswith() now accept
1071 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1072
Brett Cannonde3b0522006-06-08 17:00:45 +00001073- Buffer objects, at the C level, never used the char buffer
1074 implementation even when the char buffer for the wrapped object was
1075 explicitly requested (originally returned the read or write buffer).
1076 Now a TypeError is raised if the char buffer is not present but is
1077 requested.
1078
Georg Brandlddbaa662006-06-04 21:56:52 +00001079- Patch #1346214: Statements like "if 0: suite" are now again optimized
1080 away like they were in Python 2.4.
1081
Georg Brandlb7c8f542006-05-27 12:30:25 +00001082- Builtin exceptions are now full-blown new-style classes instead of
1083 instances pretending to be classes, which speeds up exception handling
1084 by about 80% in comparison to 2.5a2.
1085
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001086- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1087 Unicode 4.1.
1088
Georg Brandlf4ef1162006-05-26 18:03:31 +00001089- Patch #921466: sys.path_importer_cache is now used to cache valid and
1090 invalid file paths for the built-in import machinery which leads to
1091 fewer open calls on startup.
1092
Tim Peters696cf432006-05-24 21:10:40 +00001093- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1094 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1095 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1096 the number of input digits (it was and remains linear-time for bases
1097 2, 4, 8, 16 and 32).
1098
Tim Petersb713ec22006-05-23 18:45:30 +00001099- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1100 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1101 an integer close to ``sys.maxint``. This was repaired by patch
1102 #1335972, which also gives a nice speedup.
1103
Richard Jonescebbefc2006-05-23 18:28:17 +00001104- Patch #1337051: reduced size of frame objects.
1105
1106- PyErr_NewException now accepts a tuple of base classes as its
1107 "base" parameter.
1108
Richard Jones7c88dcc2006-05-23 10:37:38 +00001109- Patch #876206: function call speedup by retaining allocated frame
1110 objects.
1111
Georg Brandl7b90e162006-05-18 07:01:27 +00001112- Bug #1462152: file() now checks more thoroughly for invalid mode
1113 strings and removes a possible "U" before passing the mode to the
1114 C library function.
1115
Neal Norwitz1004a532006-05-15 07:17:23 +00001116- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1117
Neal Norwitz373f0a72006-05-15 07:04:36 +00001118- Bug #1487966: Fix SystemError with conditional expression in assignment
1119
Martin v. Löwis879768d2006-05-11 13:28:43 +00001120- WindowsError now has two error code attributes: errno, which carries
1121 the error values from errno.h, and winerror, which carries the error
1122 values from winerror.h. Previous versions put the winerror.h values
1123 (from GetLastError()) into the errno attribute.
1124
Martin v. Löwis77736712006-05-04 05:51:03 +00001125- Patch #1475845: Raise IndentationError for unexpected indent.
1126
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001127- Patch #1479181: split open() and file() from being aliases for each other.
1128
Tim Peters44bd9862006-06-01 13:49:23 +00001129- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1130 methods were always silently ignored by dictionaries when comparing keys.
1131 They are now passed through (except when using the C API function
1132 ``PyDict_GetItem()``, whose semantics did not change).
1133
1134- Bug #1456209: In some obscure cases it was possible for a class with a
1135 custom ``__eq__()`` method to confuse dict internals when class instances
1136 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1137 No, you don't have any code that did this ;-)

1145
Brett Cannon6ee7d012006-06-08 16:23:04 +00001146- Change binascii.hexlify to accept a read-only buffer instead of only a char
1147 buffer and actually follow its documentation.
1148
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001149- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1150
Nick Coghlanc649ec52006-05-29 12:43:05 +00001151- Patch #1478788 (modified version): The functional extension module has
1152 been renamed to _functools and a functools Python wrapper module added.
1153 This provides a home for additional function related utilities that are
1154 not specifically about functional programming. See PEP 309.
1155
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001156- Patch #1493701: performance enhancements for struct module.

1161 copy() method.
1162
Andrew MacIntyre92913322006-06-13 15:04:24 +00001163- Patch #1454481: thread stack size is now tunable at runtime for thread
1164 enabled builds on Windows and systems with Posix threads support.
1165
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001166- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1167 (up to the system limit of 32K characters).
1168
1169- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1170 As a result, these functions now raise WindowsError instead of OSError.
1171
Tim Peters7a822da2006-05-25 21:50:17 +00001172- ``time.clock()`` on Win64 should use the high-performance Windows
1173 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1174 Windows platforms).
1175
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001176- Calling Tk_Init twice is refused if the first call failed as that
1177 may deadlock.
1178
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001179- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1180 accept it without potentially using an uninitialized pointer.
1181
1182- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1183 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

Gregory P. Smithff7d9912006-06-08 05:17:08 +00001196- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1197 aborts the db transaction safely when a modifier callback fails.
1198 Fixes SF python patch/bug #1408584.

Gregory P. Smith506f7b52006-06-15 08:52:32 +00001200- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001201 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001202 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1203 database calls that would previously deadlock. [SF python bug #775414]

Martin v. Löwisd8251432006-06-14 05:21:04 +00001232- Patch #1455898: The MBCS codec now supports the incremental mode for
1233 double-byte encodings.
1234
Tim Peters43898b42006-06-14 04:09:25 +00001235- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1236 guarantee that adjacent triples in the return list always describe
1237 non-adjacent blocks. Previously, a pair of matching blocks could end
1238 up being described by multiple adjacent triples that formed a partition
1239 of the matching pair.

1247 clarify docs.
1248
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001249- The wsgiref package has been added to the standard library.
1250
Nick Coghlan676725d2006-06-08 13:54:49 +00001251- The functions update_wrapper() and wraps() have been added to the functools
1252 module. These make it easier to copy relevant metadata from the original
1253 function when writing wrapper functions.
1254
Tim Petersd6a9eef2006-06-05 01:48:21 +00001255- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1256 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001257
Martin v. Löwis3f767792006-06-04 19:36:28 +00001258- Patch #1359618: Speed up charmap encoder by using a trie structure
1259 for lookup.
1260
Tim Petersd609b1a2006-06-02 23:22:51 +00001261- The functions in the ``pprint`` module now sort dictionaries by key
1262 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1263 if and only if its display required more than one line, although that
1264 wasn't documented. The new behavior increases predictability; e.g.,
1265 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1266
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001267- Patch #1497027: try HTTP digest auth before basic auth in urllib2

Georg Brandlb89316f2006-05-17 15:51:16 +00001277- Patch #1180296: Two new functions were added to the locale module:
1278 format_string() to get the effect of "format % items" but locale-aware,
1279 and currency() to format a monetary number with currency sign.

1282 and several features added, such as speed and geometry control.
1283
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001284- Patch #1488881: add support for external file objects in bz2 compressed
1285 tarfiles.
1286
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001287- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1288 stdout arguments, making it possible to redirect input and output
1289 for remote debugging.
1290
1291- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1292 a couple of issues, notably handling of long file names using the
1293 GNU LONGNAME extension.
1294
1295- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1296 new flag when ``name`` is already the name of an option flag.
1297
1298- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1299 package.
1300
1301- Patch #1472854: make the rlcompleter.Completer class usable on non-
1302 UNIX platforms.
1303

1341
1342Core and builtins
1343-----------------
1344
Thomas Heller1b046642006-04-18 18:51:06 +00001345- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1346 by converting these apis from macros into exported functions again:
1347
1348 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1349 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1350 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1351 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1352 PyRun_String Py_CompileString
1353
Martin v. Löwis45294a92006-04-18 06:24:08 +00001354- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1355
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001356- All uses of PyStructSequence_InitType have been changed to initialize
1357 the type objects only once, even if the interpreter is initialized
1358 multiple times.
1359
Neal Norwitz61546162006-04-14 05:20:28 +00001360- Bug #1454485, array.array('u') could crash the interpreter. This was
1361 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1362 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1363
1364- Py_UNICODE is unsigned. It was always documented as unsigned, but
1365 due to a bug had a signed value in previous versions.
1366
Tim Peters3a5e8b12006-04-11 01:44:07 +00001367- Patch #837242: ``id()`` of any Python object always gives a positive
1368 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1369 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001370 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001371 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001372
Tim Peters3a5e8b12006-04-11 01:44:07 +00001373 def __hash__(self):
1374 return id(self) # WRONG
1375
1376 because a hash result must be a (short) Python int but it was always
1377 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001378 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001379 was always usable as a hash value before this patch. That's no longer
1380 necessarily so.
1381
1382- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001383 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001384 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001385 #1454844)
1386
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001387- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1388 involving generators that have paused outside of any ``try`` or ``with``
1389 blocks. (In 2.5a1, a paused generator that was part of a reference
1390 cycle could not be garbage collected, regardless of whether it was
1391 paused in a ``try`` or ``with`` block.)

1421 abusing errno.
1422
Tim Peters711bf302006-04-25 03:31:36 +00001423- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1424 a doctest to be skipped (the code is not run, and the expected output
1425 or exception is ignored).
1426
Nick Coghlanda2268f2006-04-24 04:37:15 +00001427- Fixed contextlib.nested to cope with exceptions being raised and
1428 caught inside exit handlers.
1429
Greg Wardab05edc2006-04-23 03:47:58 +00001430- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1431 hex, octal, or binary; add ``append_const`` action; keep going if
1432 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1433 added ``epilog`` for better help generation).
1434
Tim Peters21fbd572006-04-21 21:18:10 +00001435- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1436 called from a thread spawned as a side effect of importing a module.
1437
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001438- The pydoc module now supports documenting packages contained in
1439 .zip or .egg files.
1440
1441- The pkgutil module now has several new utility functions, such
1442 as ``walk_packages()`` to support working with packages that are either
1443 in the filesystem or zip files.
1444
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001445- The mailbox module can now modify and delete messages from
1446 mailboxes, in addition to simply reading them. Thanks to Gregory
1447 K. Johnson for writing the code, and to the 2005 Google Summer of
1448 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001449
Tim Petersc7605f22006-04-17 21:12:33 +00001450- The ``__del__`` method of class ``local`` in module ``_threading_local``
1451 returned before accomplishing any of its intended cleanup.
1452
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001453- Patch #790710: Add breakpoint command lists in pdb.

Nick Coghlanda2268f2006-04-24 04:37:15 +00001502- test_contextlib now checks contextlib.nested can cope with exceptions
1503 being raised and caught inside exit handlers.
1504
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001505- test_cmd_line now checks operation of the -m and -c command switches
1506
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001507- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1508 it separately and by hand. It also wasn't cleaning up its changes to
1509 the current Decimal context.
1510
Thomas Woutersabd08882006-04-26 15:53:30 +00001511- regrtest.py now has a -M option to run tests that test the new limits of
1512 containers, on 64-bit architectures. Running these tests is only sensible
1513 on 64-bit machines with more than two gigabytes of memory. The argument
1514 passed is the maximum amount of memory for the tests to use.

1523-------------
1524
Tim Petersb06d28c2006-05-12 01:57:59 +00001525- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1526
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001527- PEP 343: Added Context Types section to the library reference
1528 and attempted to bring other PEP 343 related documentation into
1529 line with the implementation and/or python-dev discussions.
1530
Tim Peters8dc73d22006-04-24 02:03:16 +00001531- Bug #1337990: clarified that ``doctest`` does not support examples
1532 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001540Core and builtins
1541-----------------
1542
Nick Coghlan43832302006-04-23 17:04:07 +00001543- PEP 338: -m command line switch now delegates to runpy.run_module
1544 allowing it to support modules in packages and zipfiles
1545
Martin v. Löwisc661b882006-04-20 04:54:23 +00001546- On Windows, .DLL is not an accepted file name extension for
1547 extension modules anymore; extensions are only found if they
1548 end in .PYD.
1549
Martin v. Löwisea62d252006-04-03 10:56:49 +00001550- Bug #1421664: sys.stderr.encoding is now set to the same value as
1551 sys.stdout.encoding.
1552
Neal Norwitz92e212f2006-04-03 04:48:37 +00001553- __import__ accepts keyword arguments.
1554
Georg Brandlccadf842006-03-31 18:54:53 +00001555- Patch #1460496: round() now accepts keyword arguments.
1556
Anthony Baxter262c00a2006-03-30 10:53:17 +00001557- Fixed bug #1459029 - unicode reprs were double-escaped.
1558
Hye-Shik Changd478f342006-03-23 12:32:36 +00001559- Patch #1396919: The system scope threads are reenabled on FreeBSD
1560 5.4 and later versions.
1561
Neal Norwitze98ccf62006-03-23 05:39:47 +00001562- Bug #1115379: Compiling a Unicode string with an encoding declaration
1563 now gives a SyntaxError.
1564
Georg Brandlabd1ff82006-03-18 07:59:59 +00001565- Previously, Python code had no easy way to access the contents of a
1566 cell object. Now, a ``cell_contents`` attribute has been added
1567 (closes patch #1170323).
1568
Tim Peterscf79aac2006-03-16 01:14:46 +00001569- Patch #1123430: Python's small-object allocator now returns an arena to
1570 the system ``free()`` when all memory within an arena becomes unused
1571 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1572 freed. Some applications will see a drop in virtual memory size now,
1573 especially long-running applications that, from time to time, temporarily
1574 use a large number of small objects. Note that when Python returns an
1575 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001576 platform C library will in turn return that memory to the operating system.
1577 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001578 appears to be effective at least on Microsoft C and gcc-based systems.
1579 Thanks to Evan Jones for hard work and patience.
1580
Georg Brandl533ff6f2006-03-08 18:09:27 +00001581- Patch #1434038: property() now uses the getter's docstring if there is
1582 no "doc" argument given. This makes it possible to legitimately use
1583 property() as a decorator to produce a read-only property.
1584
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001585- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1586 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1587 of requiring an int or long in slicing and a few other contexts, enabling
1588 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1589
Neal Norwitz995acdf2006-03-07 05:01:00 +00001590- Fixed various bugs reported by Coverity's Prevent tool.
1591
Brett Cannonbf364092006-03-01 04:25:17 +00001592- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1593 new exception base class, BaseException, which has a new message attribute.
1594 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1595 Raising a string exception now raises a DeprecationWarning.
1596
Thomas Woutersfb609f42006-02-28 16:37:25 +00001597- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1598 explicitly relative, using 'from .module import name' to mean 'from the same
1599 package as this module is in. Imports without dots still default to the
1600 old relative-then-absolute, unless 'from __future__ import
1601 absolute_import' is used.
1602
Brett Cannona7446e32006-02-27 23:39:10 +00001603- Properly check if 'warnings' raises an exception (usually when a filter set
1604 to "error" is triggered) when raising a warning for raising string
1605 exceptions.
1606
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001607- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001608 The name was removed from Include/code.h.
1609
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001610- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001611
Guido van Rossum1968ad32006-02-25 22:38:04 +00001612- Patch 1433928:
1613 - The copy module now "copies" function objects (as atomic objects).
1614 - dict.__getitem__ now looks for a __missing__ hook before raising
1615 KeyError.
1616
Tim Peters84ef21c2006-02-28 20:39:06 +00001617- PEP 343: with statement implemented. Needs ``from __future__ import
1618 with_statement``. Use of 'with' as a variable will generate a warning.
1619 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001620 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001621 The following objects have __context__ methods:
1622 - The built-in file type.
1623 - The thread.LockType type.
1624 - The following types defined by the threading module:
1625 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1626 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001627
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001628- Fix the encodings package codec search function to only search
1629 inside its own package. Fixes problem reported in patch #1433198.
1630
1631 Note: Codec packages should implement and register their own
1632 codec search function. PEP 100 has the details.
1633
Tim Peters9ea89d22006-06-04 03:26:02 +00001634- PEP 353: Using ``Py_ssize_t`` as the index type.
1635
1636- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1637 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1638 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1639 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1640 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001641
Neal Norwitzfc76d632006-01-10 06:03:13 +00001642- Patch #1400181, fix unicode string formatting to not use the locale.
1643 This is how string objects work. u'%f' could use , instead of .
1644 for the decimal point. Now both strings and unicode always use periods.
1645
Neal Norwitz671b9e32006-01-09 07:07:12 +00001646- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1647 configure would break checking curses.h.
1648
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001649- Bug #959576: The pwd module is now builtin. This allows Python to be
1650 built on UNIX platforms without $HOME set.
1651
Neal Norwitzc10978f2005-12-19 06:07:16 +00001652- Bug #1072182, fix some potential problems if characters are signed.
1653
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001654- Bug #889500, fix line number on SyntaxWarning for global declarations.
1655
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001656- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1657
Neal Norwitze7214a12005-12-18 05:03:17 +00001658- Support for converting hex strings to floats no longer works.
1659 This was not portable. float('0x3') now raises a ValueError.
1660
Barry Warsaw2a38a862005-12-18 01:27:35 +00001661- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001662 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001663 is now displayed in interactive prompt banner.
1664
Georg Brandlfa166682005-12-17 21:45:17 +00001665- Implementation of PEP 341 - Unification of try/except and try/finally.
1666 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001667 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001668
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001669- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1670 now encodes backslash correctly.
1671
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001672- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1673
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001674- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001675 and long longs.
1676
Neal Norwitz67715f02005-11-09 06:59:35 +00001677- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001678 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001679 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001680
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001681- Replaced most Unicode charmap codecs with new ones using the
1682 new Unicode translate string feature in the builtin charmap
1683 codec; the codecs were created from the mapping tables available
1684 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1685 encodings now include a mapping for the Apple logo)
1686
Tim Peterse3547fd2005-12-16 23:13:57 +00001687- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001688
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001689- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001690
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001691- A new AST parser implementation was completed. The abstract
1692 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001693 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001694
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001695- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001696 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1697
Neal Norwitz708e51a2005-10-03 04:48:15 +00001698- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1699
Neal Norwitz11bd1192005-10-03 00:54:56 +00001700- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1701 Provide a warning when a directory is passed on the command line.
1702
Neal Norwitz40d37812005-10-02 01:48:49 +00001703- Fix segfault with invalid coding.
1704
1705- SF bug #772896: unknown encoding results in MemoryError.
1706
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001707- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001708 supported a __len__() method which evaluated to False when the iterator
1709 was empty.
1710
Guido van Rossum630db602005-09-20 18:49:54 +00001711- On 64-bit platforms, when __len__() returns a value that cannot be
1712 represented as a C int, raise OverflowError.
1713
Skip Montanarof8948ca2005-09-19 03:54:46 +00001714- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001715 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001716
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001717- SF bug #893549: parsing keyword arguments was broken with a few format
1718 codes.
1719
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001720- Changes donated by Elemental Security to make it work on AIX 5.3
1721 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1722 bug #105470: test_pwd fails on 64bit system (Opteron).
1723
Guido van Rossum539c6622005-09-14 17:49:54 +00001724- Changes donated by Elemental Security to make it work on HP-UX 11 on
1725 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1726
Georg Brandl4550b8d2005-08-26 06:43:52 +00001727- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001728 (fixes bug #1119418).
1729
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001730- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1731
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001732- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1733 exceptions that cause a function to exit.
1734
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001735- The implementation of set() and frozenset() was revised to use its
1736 own internal data structure. Memory consumption is reduced by 1/3
1737 and there are modest speed-ups as well. The API is unchanged.
1738
Tim Petersde7990b2005-07-17 23:45:23 +00001739- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1740
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001741- SF bug #1229429: PyObject_CallMethod failed to decrement some
1742 reference counts in some error exit cases.
1743
Tim Petersecc6e6a2005-07-10 22:30:55 +00001744- SF bug #1185883: Python's small-object memory allocator took over
1745 a block managed by the platform C library whenever a realloc specified
1746 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001747 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001748 portable way to copy data from the C-managed block into Python's
1749 small-object space without risking a memory fault. Python's small-object
1750 realloc now leaves such blocks under the control of the platform C
1751 realloc.
1752
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001753- SF bug #1232517: An overflow error was not detected properly when
1754 attempting to convert a large float to an int in os.utime().
1755
Raymond Hettinger3296e692005-06-29 23:29:56 +00001756- SF bug #1224347: hex longs now print with lowercase letters just
1757 like their int counterparts.
1758
Michael W. Hudson188d4362005-06-20 16:52:57 +00001759- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1760 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1761 interpreter states; back out that fix and do a better job (see
1762 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1763 for a longer write-up of the problem).
1764
Michael W. Hudsondf888462005-06-03 14:41:55 +00001765- SF patch #1180995: marshal now uses a binary format by default when
1766 serializing floats.
1767
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001768- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1769 the routines that promise to produce IEEE 754 binary representations
1770 of floats now simply copy bytes around.
1771
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001772- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1773 278.
1774
Brett Cannonc3647ac2005-04-26 03:45:26 +00001775- patch #1109424: int, long, float, complex, and unicode now check for the
1776 proper magic slot for type conversions when subclassed. Previously the
1777 magic slot was ignored during conversion. Semantics now match the way
1778 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001779 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001780 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001781 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001782
Barry Warsawc8d907c2005-04-19 23:43:40 +00001783- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1784 NULL, now raise an AttributeError when attempting to set or delete the
1785 attribute. Previously a TypeError was raised, but this was inconsistent
1786 with the equivalent pure-Python implementation.
1787
Michael W. Hudson774479c2005-04-18 08:46:17 +00001788- It is now safe to call PyGILState_Release() before
1789 PyEval_InitThreads() (note that if there is reason to believe there
1790 are multiple threads around you still must call PyEval_InitThreads()
1791 before using the Python API; this fix is for extension modules that
1792 have no way of knowing if Python is multi-threaded yet).
1793
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001794- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1795 disabled caused a crash.
1796
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001797- Bug #1165306: instancemethod_new allowed the creation of a method
1798 with im_class == im_self == NULL, which caused a crash when called.
1799
Tim Petersecc6e6a2005-07-10 22:30:55 +00001800- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001801 fixes the crash seen in bug #1165761
1802
Raymond Hettinger96229b12005-03-11 06:49:40 +00001803- Added two new builtins, any() and all().
1804
Brett Cannon409d8f22005-03-05 06:47:57 +00001805- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001806 (e.g., ``class C(): pass`` is no longer a syntax error).
1807 Patch #1176012 added support to the 'parser' module and 'compiler' package
1808 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001809
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001810- Patch #1115086: Support PY_LONGLONG in structmember.
1811
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001812- Bug #1155938: new style classes did not check that __init__() was
1813 returning None.
1814
Tim Petersecc6e6a2005-07-10 22:30:55 +00001815- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001816 ('\') with a specific error message.
1817
Martin v. Löwisff232d72005-03-03 09:24:38 +00001818- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1819
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001820- Bug #1124295: the __name__ attribute of file objects was
1821 inadvertently made inaccessible in restricted mode.
1822
Tim Petersecc6e6a2005-07-10 22:30:55 +00001823- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001824 an ferror() call.
1825
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001826- min() and max() now support key= arguments with the same meaning as in
1827 list.sort().
1828
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001829- The peephole optimizer now performs simple constant folding in expressions:
1830 (2+3) --> (5).
1831
Raymond Hettingera422c342005-01-11 03:03:27 +00001832- set and frozenset objects can now be marshalled. SF #1098985.
1833
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001834- Bug #1077106: Poor argument checking could cause memory corruption
1835 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001836
Jeremy Hyltonab630502005-02-04 18:44:06 +00001837- The parser did not complain about future statements in illegal
1838 positions. It once again reports a syntax error if a future
1839 statement occurs after anything other than a doc string.
1840
Neil Schemenauercf52c072005-08-12 17:34:58 +00001841- Change the %s format specifier for str objects so that it returns a
1842 unicode instance if the argument is not an instance of basestring and
1843 calling __str__ on the argument returns a unicode instance.
1844
Tim Petersf4e69282006-02-27 17:15:31 +00001845- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1846 current thread state when the auto-GIL-state machinery knows about
1847 it (since the thread state is being deleted, continuing to remember it
1848 can't help, but can hurt if another thread happens to get created with
1849 the same thread id).
1850

1879 for applications that require this specific version (such as IDNA).
1880
Neal Norwitzb62c4332006-03-04 18:35:47 +00001881- The timing module is no longer built by default. It was deprecated

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002041- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2042 been renamed to have only a single underscore prefix. This was done to
2043 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002044
Nick Coghlan43832302006-04-23 17:04:07 +00002045- PEP 338: new module runpy defines a run_module function to support
2046 executing modules which provide access to source code or a code object
2047 via the PEP 302 import mechanisms.
2048
Anthony Baxter93f5b932006-04-03 08:05:07 +00002049- The email module's parsedate_tz function now sets the daylight savings
2050 flag to -1 (unknown) since it can't tell from the date whether it should
2051 be set.
2052
Fred Drakead5177c2006-04-01 22:14:43 +00002053- Patch #624325: urlparse.urlparse() and urlparse.urlsplit() results
2054 now sport attributes that provide access to the parts of the result.
2055

2057 in attribute values.
2058
Anthony Baxterc51ee692006-04-01 00:57:31 +00002059- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002060 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002061 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002062 module will not be built.
2063
Tim Petersc17976e2006-04-01 00:26:53 +00002064- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2065 aren't officially supported here, and trying to use them will probably
2066 raise an exception some day. But dicts have been allowed, and "mostly
2067 worked", so support for them won't go away without warning.
2068
Georg Brandl338ef7d2006-03-31 18:42:16 +00002069- Bug #1445068: getpass.getpass() can now be given an explicit stream
2070 argument to specify where to write the prompt.
2071
Georg Brandl22ec80b2006-03-31 18:25:44 +00002072- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2078 key to be used for signing the uploaded code.
2079
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002080- Queue.Queue objects now support .task_done() and .join() methods
2081 to make it easier to monitor when daemon threads have completed
2082 processing all enqueued tasks. Patch #1455676.
2083
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002084- popen2.Popen objects now preserve the command in a .cmd attribute.
2085
Thomas Hellerc61c0492006-03-22 10:09:27 +00002086- Added the ctypes ffi package.
2087
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002088- email 4.0 package now integrated. This is largely the same as the email 3.0
2089 package that was included in Python 2.3, except that PEP 8 module names are
2090 now used (e.g. mail.message instead of email.Message). The MIME classes
2091 have been moved to a subpackage (e.g. email.mime.text instead of
2092 email.MIMEText). The old names are still supported for now. Several
2093 deprecated Message methods have been removed and lots of bugs have been
2094 fixed. More details can be found in the email package documentation.
2095
Walter Dörwald40108c92006-03-27 08:15:44 +00002096- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2097 (a subclass of tuple) that provides incremental decoders and encoders
2098 (a way to use stateful codecs without the stream API). Python functions
2099 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2100 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2101 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002102
Walter Dörwald067db482006-03-15 22:17:27 +00002103- Patch #1359365: Calling next() on a closed StringIO.String object raises
2104 a ValueError instead of a StopIteration now (like file and cString.String do).
2105 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2106 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002107
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002108- A regrtest option -w was added to re-run failed tests in verbose mode.

2111 interpreter to exit.
2112
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002113- The function get_count() has been added to the gc module, and gc.collect()

2120 and helpful context managers nested() and closing().
2121

Martin v. Löwis3e865952006-01-24 15:51:21 +00002156 specifications, raises IOErrors when proxies for unsupported protocols

2181 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2182 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2183 Ronald L. Rivest offered this advice for Python:
2184
2185 "The consensus of researchers in this area (at least as
2186 expressed at the NIST Hash Function Workshop 10/31/05),
2187 is that SHA-256 is a good choice for the time being, but
2188 that research should continue, and other alternatives may
2189 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002190
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002191- Added a subset of Fredrik Lundh's ElementTree package. Available

2297 support for datetime.{datetime,date,time} objects. With use_datetime set
2298 to True, applications shouldn't have to fiddle with the DateTime wrapper
2299 class at all.
2300
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002301- distutils.commands.upload was added to support uploading distribution
2302 files to PyPI.
2303
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002304- distutils.commands.register now encodes the data as UTF-8 before posting
2305 them to PyPI.
2306
Raymond Hettinger267b8682005-03-27 10:47:39 +00002307- decimal operator and comparison methods now return NotImplemented
2308 instead of raising a TypeError when interacting with other types. This
2309 allows other classes to implement __radd__ style methods and have them
2310 work as expected.
2311
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002312- Bug #1163325: Decimal infinities failed to hash. Attempting to
2313 hash a NaN raised an InvalidOperation instead of a TypeError.
2314
Tim Petersecc6e6a2005-07-10 22:30:55 +00002315- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002316 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2317
Martin v. Löwis00a73e72005-03-04 19:40:34 +00002318- Patch #1043890: Add extractall method to tarfile.
2319
Martin v. Löwisc72dd382005-03-04 13:50:17 +00002320- Patch #1075887: Don't require MSVC in distutils if there is nothing
2321 to build.
2322
Martin v. Löwis637431b2005-03-03 23:12:42 +00002323- Patch #1103407: Properly deal with tarfile iterators when untarring
2324 symbolic links on Windows.
2325
Tim Petersecc6e6a2005-07-10 22:30:55 +00002326- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +00002327 profile.py if available.
2328
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00002329- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
2330
Martin v. Löwisc5574e82005-03-03 10:57:37 +00002331- Patch #1117454: Remove code to special-case cookies without values
2332 in LWPCookieJar.
2333
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00002334- Patch #1117339: Add cookielib special name tests.
2335
Martin v. Löwise869eb12005-03-03 09:46:07 +00002336- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
2337
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00002338- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
2339
Martin v. Löwisdf241532005-03-03 08:17:42 +00002340- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
2341
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00002342- Patch #1104111: Alter setup.py --help and --help-commands.
2343
Martin v. Löwis4afe1542005-03-01 08:09:28 +00002344- Patch #1121234: Properly cleanup _exit and tkerror commands.
2345
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00002346- Patch #1049151: xdrlib now unpacks booleans as True or False.
2347
Raymond Hettingerbab41432005-02-05 01:31:19 +00002348- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2349
Guido van Rossumd0641422005-02-03 15:01:24 +00002350- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2351 disables recursive traversal through instance attributes, which can
2352 be exploited in various ways.
2353
Tim Peterse3547fd2005-12-16 23:13:57 +00002354- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002355 flags on the HTTP listening socket.
2356
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002357- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2358 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2359
Fred Drakefbdeaad2006-07-29 16:56:15 +00002360- Patches #893642, #1039083: add allow_none, encoding arguments to
2361 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002362
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002363- Bug #1110478: Revert os.environ.update to do putenv again.
2364
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002365- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2366
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002367- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2368
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002369- Enhancements to the csv module:
2370
2371 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002372 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002373 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002374 + Dialect parameter parsing has been re-implemented to improve error
2375 reporting.
2376 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2377 dictates.
2378 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002379 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002380 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002381 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2382 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002383 + reader now allows \r characters to be quoted (previously it only allowed
2384 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002385 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002386 + Dialect classes passed to the module are no longer instantiated by
2387 the module before being parsed (the former validation scheme required
2388 this, but the mechanism was unreliable).
2389 + The dialect registry now contains instances of the internal
2390 C-coded dialect type, rather than references to python objects.
2391 + the internal c-coded dialect type is now immutable.
2392 + register_dialect now accepts the same keyword dialect specifications
2393 as the reader and writer, allowing the user to register dialects
2394 without first creating a dialect class.
2395 + a configurable limit to the size of parsed fields has been added -
2396 previously, an unmatched quote character could result in the entire
2397 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002398 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002399 the parser field size limit (returning the former limit). The initial
2400 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002401 + A line_num attribute has been added to the reader object, which tracks
2402 the number of lines read from the source iterator. This is not
2403 the same as the number of records returned, as records can span
2404 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002405 + reader and writer objects were not being registered with the cyclic-GC.
2406 This has been fixed.
2407
Brett Cannone6539c42005-01-08 02:43:53 +00002408- _DummyThread objects in the threading module now delete self.__block that is
2409 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2410 lock primitives tend to be limited in number and thus should not be wasted on
2411 a _DummyThread object. Fixes bug #1089632.
2412
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002413- The imghdr module now detects Exif files.
2414
Raymond Hettinger6065d322004-12-20 23:51:53 +00002415- StringIO.truncate() now correctly adjusts the size attribute.
2416 (Bug #951915).
2417
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002418- locale.py now uses an updated locale alias table (built using
2419 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2420 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002421 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002422
Raymond Hettinger3557f422004-12-07 12:02:02 +00002423- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2424
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002425- the pickle module no longer accepts the deprecated None option in the
2426 args tuple returned by __reduce__().
2427
Brett Cannon84667c02004-12-07 03:25:18 +00002428- optparse now optionally imports gettext. This allows its use in setup.py.
2429
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002430- the pickle module no longer uses the deprecated bin parameter.
2431
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002432- the shelve module no longer uses the deprecated binary parameter.
2433
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002434- the pstats module no longer uses the deprecated ignore() method.
2435
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002436- the filecmp module no longer uses the deprecated use_statcache argument.
2437
Raymond Hettinger664347b2004-12-04 21:21:53 +00002438- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2439 extended or overridden by subclasses. Formerly, the subclassed method would
2440 be ignored by the rest of the module. (Bug #1078905).
2441
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002442- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002443 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002444
Walter Dörwald36733692004-12-22 12:50:50 +00002445- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2446 once when a size argument is given. This prevents a buffer overflow in the
2447 tokenizer with very long source lines.
2448
Barry Warsaw538561e2006-01-01 21:48:54 +00002449- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2450 immediately after creating the object, without any intervening
2451 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002452
Skip Montanaro05885812005-01-16 20:48:27 +00002453- The reconvert.quote function can now emit triple-quoted strings. The
2454 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002455
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002456- ``UserString.MutableString`` now supports negative indices in
2457 ``__setitem__`` and ``__delitem__``
2458
Greg Ward40407942005-03-05 02:53:17 +00002459- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2460 correctly.
2461
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002462- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2463 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2464 character even if the user has passed a size parameter to get a proper
2465 line ending. Remove the special handling of a "\r\n" that has been split
2466 between two lines.
2467
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002468- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2469 about illegal code points. The codec now supports PEP 293 style error
2470 handlers.
2471
Walter Dörwald78a78b02005-09-01 12:04:29 +00002472- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002473 from the input stream, so that the output is a byte string in the correct
2474 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002475
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002476- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2477 considering it exactly like a '*'.
2478
Walter Dörwald007f8df2005-10-09 19:42:27 +00002479- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2480 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002481
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002482- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2483
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002484- Patch #1413711: Certain patterns of differences were making difflib
2485 touch the recursion limit.
2486
Walter Dörwald58917a62006-03-31 15:26:22 +00002487- Bug #947906: An object oriented interface has been added to the calendar
2488 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002489 called as a script (e.g. via ``python -mcalendar``). Localized month and
2490 weekday names can be ouput (even if an exotic encoding is used) using
2491 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002492
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002493Build
2494-----
2495
Neal Norwitz602d3392006-03-31 08:21:40 +00002496- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2497 by using -mieee gcc option.
2498
Martin v. Löwis86d66262006-02-17 08:40:11 +00002499- Patch #1432345: Make python compile on DragonFly.
2500
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002501- Build support for Win64-AMD64 was added.
2502
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002503- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2504
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002505- Patch #881820: look for openpty and forkpty also in libbsd.
2506
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002507- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2508 The zlib module is now builtin on Windows.
2509
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002510- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2511
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002512- Bug #1189330: configure did not correctly determine the necessary
2513 value of LINKCC if python was built with GCC 4.0.
2514
Trent Mick8321b422005-07-26 02:29:21 +00002515- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2516 vulnerability in zlib 1.2.1 and 1.2.2.
2517
Brett Cannon08cd5982005-04-24 22:26:38 +00002518- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2519 flags that change binary compatibility. Changes were also made to
2520 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002521 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002522
Bob Ippolitoed233462005-03-29 13:47:59 +00002523- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2524 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2525 no longer exists). This configure patch makes things right.
2526
Martin v. Löwise2713be2005-03-08 15:03:08 +00002527- Bug #1158607: Build with --disable-unicode again.
2528
Brett Cannon46d96232005-02-16 00:07:19 +00002529- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2530 defined. Discovered as a result of not being able to build on OS X.
2531
Brett Cannon516592f2004-12-07 00:42:59 +00002532- setup.py now uses the directories specified in LDFLAGS using the -L option
2533 and in CPPFLAGS using the -I option for adding library and include
2534 directories, respectively, for compiling extension modules against. This has
2535 led to the core being compiled using the values in CPPFLAGS. It also removes
2536 the need for the special-casing of both DarwinPorts and Fink for darwin since
2537 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2538 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2539 Fink, ``-I/opt/local/include`` for DarwinPorts).
2540
Brett Cannon43802422005-02-10 20:48:03 +00002541- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2542 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2543 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2544 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002546C API
2547-----
2548
Tim Petersc9d78aa2006-03-26 23:27:58 +00002549- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2550 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2551 is obtained via the ``PyObject_`` family, it must be released via the
2552 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2553 always been officially true, but when Python's small-object allocator was
2554 introduced, an attempt was made to cater to a few extension modules
2555 discovered at the time that obtained memory via ``PyObject_New`` but
2556 released it via ``PyMem_DEL``. It's years later, and if such code still
2557 exists it will fail now (probably with segfaults, but calling wrong
2558 low-level memory management functions can yield many symptoms).
2559
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002560- Added a C API for set and frozenset objects.
2561
