Andrew M. Kuchling830358a2006-11-17 16:16:28 +0000309- mailbox.py: Change MH.pack() to not lock individual message files; this

385
Brett Cannon19d76c52006-09-09 07:18:44 +0000386- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
387 allows calling unicode() on exceptions classes directly to succeed.
388
Georg Brandlecab6232006-09-06 06:47:02 +0000389- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

406
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000407- Bug #1520864: unpacking singleton tuples in list comprehensions and
408 generator expressions (x for x, in ... ) works again. Fixing this problem
409 required changing the .pyc magic number. This means that .pyc files
410 generated before 2.5c2 will be regenerated.

521- Fix concatenation (+=) of long strings.
522
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000523- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000524 compared equal or unequal to a string and a UnicodeDecodeError
525 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000526
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000527 Instead, the equal (==) and unequal (!=) comparison operators will
528 now issue a UnicodeWarning and interpret the two objects as
529 unequal. The UnicodeWarning can be filtered as desired using
530 the warning framework, e.g. silenced completely, turned into an
531 exception, logged, etc.
532
533 Note that compare operators other than equal and unequal will still
534 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000535
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000536- Fix segfault when doing string formatting on subclasses of long.

540
541- Fix bug related to __len__ functions returning negative values with
542 classic classes.
543
544- Patch #1538606, Fix __index__() clipping. There were some problems
545 discovered with the API and how integers that didn't fit into Py_ssize_t
546 were handled. This patch attempts to provide enough alternatives
547 to effectively use __index__.
548
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000549- Bug #1536021: __hash__ may now return long int; the final hash
550 value is obtained by invoking hash on the long int.
551
Thomas Hellerab1049c2006-08-08 17:37:00 +0000552- Bug #1536786: buffer comparison could emit a RuntimeWarning.

555 sys.stdin is closed.
556
Thomas Heller74d36f02006-08-04 18:17:40 +0000557- On Windows, the PyErr_Warn function is now exported from
558 the Python dll again.
559
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000560- Bug #1191458: tracing over for loops now produces a line event
561 on each iteration. Fixing this problem required changing the .pyc
562 magic number. This means that .pyc files generated before 2.5c1
563 will be regenerated.
564
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000565- Bug #1333982: string/number constants were inappropriately stored
566 in the byte code and co_consts even if they were not used, ie
567 immediately popped off the stack.

576 generated for generator expressions.
577
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000578- The distutils version has been changed to 2.5.0. The change to
579 keep it programmatically in sync with the Python version running
580 the code (introduced in 2.5b3) has been reverted. It will continue
581 to be maintained manually as static string literal.
582
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000583- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000584 and this cannot be converted to the required C type, an exception is
585 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000586 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000587
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000588- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000589 an exception.
590
Tim Peterscbdd3502006-09-05 01:47:53 +0000591- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000592 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000593 workarounds for clocks with low resolution, to stop the code yielding
594 duplicate UUIDs.
595
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000596- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
597 before raising SystemExit, allowing IDLE to honor quit() and exit().
598
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000599- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.

628
Thomas Heller86720042006-08-14 11:17:48 +0000629- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
630 uses the _as_parameter_ attribute when objects are passed to foreign
631 function calls. The ctypes version number was changed to 1.0.1.
632
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000633- Bug #1530559, struct.pack raises TypeError where it used to convert.
634 Passing float arguments to struct.pack when integers are expected
635 now triggers a DeprecationWarning.

Fred Drake53912162006-07-29 13:22:49 +0000680What's New in Python 2.5 beta 3?
681================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000682
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000683*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000684
685Core and builtins
686-----------------
687
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000688- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000689 returned a long (see PEP 353).
690
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000691- Bug #1515471: string.replace() accepts character buffers again.
692
Neal Norwitz07aadb12006-07-30 06:55:48 +0000693- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
694 This provides the proper warning for struct.pack().
695 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
696
Neal Norwitz0d62a062006-07-30 06:53:31 +0000697- Patch #1531113: Fix augmented assignment with yield expressions.
698 Also fix a SystemError when trying to assign to yield expressions.
699
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000700- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
701 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
702 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
703 excessive filesystem operations during imports.
704
Tim Petersbc24eee2006-07-27 01:14:53 +0000705- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
706 operations on signed longs that are formally undefined by C.
707 Unfortunately, at least one compiler now cares about that, so complicated
708 the code to make that compiler happy again.
709
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000710- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
711
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000712- Patch #1232023: Stop including current directory in search
713 path on Windows.
714
Neal Norwitze1fdb322006-07-21 05:32:28 +0000715- Fix some potential crashes found with failmalloc.
716
Neal Norwitze7563102006-07-17 01:00:16 +0000717- Fix warnings reported by Klocwork's static analysis tool.
718
Neal Norwitz84be93b2006-07-16 01:50:38 +0000719- Bug #1512814, Fix incorrect lineno's when code within a function
720 had more than 255 blank lines.
721
Georg Brandl9dceedb2006-07-12 15:31:17 +0000722- Patch #1521179: Python now accepts the standard options ``--help`` and
723 ``--version`` as well as ``/?`` on Windows.
724
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000725- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000726 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000727 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000728
Tim Peters112aad32006-07-19 00:03:19 +0000729- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000730 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000731 new ``sys._current_frames()`` returns a dictionary with one entry,
732 mapping the faux "thread id" 0 to the current frame.
733
Ronald Oussoren3075e162006-07-25 20:28:55 +0000734- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000735

Neal Norwitza1f10902006-07-12 07:28:29 +0000737Library
738-------
739
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000740- Correction of patch #1455898: In the mbcs decoder, set final=False
741 for stream decoder, but final=True for the decode function.
742
Georg Brandl07fec3a2006-08-01 18:49:24 +0000743- os.urandom no longer masks unrelated exceptions like SystemExit or
744 KeyboardInterrupt.
745
Tim Peters4643c2f2006-08-10 22:45:34 +0000746- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000747 shutil.copytree on Windows
748
Georg Brandle34ac7c2006-07-30 11:07:23 +0000749- Bug #1002398: The documentation for os.path.sameopenfile now correctly
750 refers to file descriptors, not file objects.
751
Tim Peterscbdd3502006-09-05 01:47:53 +0000752- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000753 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000754 #1513611, and probably others.
755
Georg Brandledd9b0d2006-07-29 09:33:26 +0000756- Bug #1441397: The compiler module now recognizes module and function
757 docstrings correctly as it did in Python 2.4.
758
Tim Peters6f681472006-07-27 23:44:37 +0000759- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
760 lost that tests are sorted by name before being run. This rarely
761 matters for well-written tests, but can create baffling symptoms if
762 side effects from one test to the next affect outcomes. ``DocTestFinder``
763 has been changed to sort the list of tests it returns.
764
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000765- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000766 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000767
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000768- Bug #978833: Really close underlying socket in _socketobject.close.
769
Georg Brandldb232dc2006-08-20 13:15:43 +0000770- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
771 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000772
Georg Brandlcf0c1722006-07-26 07:23:32 +0000773- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
774 to recursive calls and call it with the failing package name.
775
Martin v. Löwis0b483032006-07-25 09:53:12 +0000776- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
777
Georg Brandlc13c34c2006-07-24 14:09:56 +0000778- Patch #1515343: Fix printing of deprecated string exceptions with a
779 value in the traceback module.
780
Greg Ward48fae7a2006-07-23 16:05:51 +0000781- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
782
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000783- Patch #1524429: Use repr() instead of backticks in Tkinter again.
784
Brett Cannoncaebe222006-07-18 04:41:36 +0000785- Bug #1520914: Change time.strftime() to accept a zero for any position in its
786 argument tuple. For arguments where zero is illegal, the value is forced to
787 the minimum value that is correct. This is to support an undocumented but
788 common way people used to fill in inconsequential information in the time
789 tuple pre-2.4.
790
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000791- Patch #1220874: Update the binhex module for Mach-O.
792
Barry Warsawb110bad2006-07-21 14:51:07 +0000793- The email package has improved RFC 2231 support, specifically for
794 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
795 (name*0=<blah>) parameter continuations. This may change the types of
796 values returned from email.message.Message.get_param() and friends.
797 Specifically in some cases where non-encoded continuations were used,
798 get_param() used to return a 3-tuple of (None, None, string) whereas now it
799 will just return the string (since non-encoded continuations don't have
800 charset and language parts).
801
802 Also, whereas % values were decoded in all parameter continuations, they are
803 now only decoded in encoded parameter parts.
804
Ronald Oussoren3075e162006-07-25 20:28:55 +0000805- Bug #1517990: IDLE keybindings on MacOS X now work correctly
806
807- Bug #1517996: IDLE now longer shows the default Tk menu when a
808 path browser, class browser or debugger is the frontmost window on MacOS X
809
Barry Warsaw00decd72006-07-27 23:43:15 +0000810- Patch #1520294: Support for getset and member descriptors in types.py,
811 inspect.py, and pydoc.py. Specifically, this allows for querying the type
812 of an object against these built-in types and more importantly, for getting
813 their docstrings printed in the interactive interpreter's help() function.

818
Neal Norwitz9b0ca792006-08-02 06:46:21 +0000819- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
820 a socket operation on a socket with a timeout, the exception will be
821 caught correctly. Previously, the exception was not caught.
822
Thomas Heller1393d6a2006-07-28 21:43:20 +0000823- Patch #1529514: The _ctypes extension is now compiled on more
824 openbsd target platforms.
825
Tim Peters9cab5932006-07-28 00:30:00 +0000826- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
827 a memory leak, affecting pickles and deep copies.
828
Tim Petersbc24eee2006-07-27 01:14:53 +0000829- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

831
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000832- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
833
Thomas Hellerce049a02006-07-14 17:51:14 +0000834- Patch #1521817: Index range checking on ctypes arrays containing
835 exactly one element enabled again. This allows iterating over these
836 arrays, without the need to check the array size before.
837
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000838- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000839 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000840 /dev/null in certain cases; this is now fixed.
841
Thomas Heller47d7a062006-07-12 08:43:47 +0000842- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
843 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000844
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000845- Because of a misspelled preprocessor symbol, ctypes was always
846 compiled without thread support; this is now fixed.
847
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000848- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
849 methods now allow their database parameter to be None as the
850 sleepycat API allows.
851
Matt Flemingec926502006-07-28 11:27:27 +0000852- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
853 bluetooth API compared with Linux and FreeBSD.
854
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000855Tests
856-----
857
858- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
859 how long the test file should take to play. Now accepts taking 2.93 secs
860 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
861
Georg Brandl4793aa32006-07-28 18:31:39 +0000862- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
863 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
864 run via ``regrtest.py``. Now they do.

873
874- PythonLauncher now works correctly when the path to the script contains
875 characters that are treated specially by the shell (such as quotes).
876
877- Bug #1527397: PythonLauncher now launches scripts with the working directory
878 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000879 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000880 expect.

893
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000894- Bug #1501934: The scope of global variables that are locally assigned

Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000903- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
904 omit a default "error" argument for NULL pointer. This allows
905 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000906
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000907- Bug #1519018: 'as' is now validated properly in import statements.
908
Neal Norwitz28746ab2006-07-09 22:14:42 +0000909- On 64 bit systems, int literals that use less than 64 bits are
910 now ints rather than longs.
911
Neal Norwitzed657552006-07-10 00:04:44 +0000912- Bug #1512814, Fix incorrect lineno's when code at module scope
913 started after line 256.
914
Tim Peters32a83612006-07-10 21:08:24 +0000915- New function ``sys._current_frames()`` returns a dict mapping thread
916 id to topmost thread stack frame. This is for expert use, and is
917 especially useful for debugging application deadlocks. The functionality
918 was previously available in Fazal Majid's ``threadframe`` extension
919 module, but it wasn't possible to do this in a wholly threadsafe way from
920 an extension.

967
Brett Cannon53ab5b72006-06-22 16:49:14 +0000968- Bug #1510580: The 'warnings' module improperly required that a Warning
969 category be either a types.ClassType and a subclass of Warning. The proper
970 check is just that it is a subclass with Warning as the documentation states.
971
Georg Brandlad29e632006-06-21 17:45:17 +0000972- The compiler module now correctly compiles the new try-except-finally
973 statement (bug #1509132).

985-----------------
986
Tim Peters112aad32006-07-19 00:03:19 +0000987- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
988 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
989 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +0000990
Thomas Hellerb9cb84f2006-07-10 11:17:37 +0000991- Assigning None to pointer type fields in ctypes structures possible
992 overwrote the wrong fields, this is fixed now.
993
994- Fixed a segfault in _ctypes when ctypes.wintypes were imported
995 on non-Windows platforms.
996
997- Bug #1518190: The ctypes.c_void_p constructor now accepts any
998 integer or long, without range checking.
999
1000- Patch #1517790: It is now possible to use custom objects in the ctypes
1001 foreign function argtypes sequence as long as they provide a from_param
1002 method, no longer is it required that the object is a ctypes type.
1003
1004- The '_ctypes' extension module now works when Python is configured
1005 with the --without-threads option.

Martin v. Löwisd73168d2006-07-14 09:58:55 +00001021- Automate Windows build process for the Win64 SSL module.
1022
Tim Peters32a83612006-07-10 21:08:24 +00001023- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001024 Previously, the slight difference could cause compilation errors of the
1025 'zlib' module on systems with more than one version of zlib.
1026
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001027- The MSI compileall step was fixed to also support a TARGETDIR

1059-----------------
1060
Georg Brandla56b9152006-06-19 06:35:54 +00001061- Patch #1507676: Error messages returned by invalid abstract object operations
1062 (such as iterating over an integer) have been improved and now include the
1063 type of the offending object to help with debugging.
1064
Brett Cannonea3912b2006-06-13 21:46:41 +00001065- Bug #992017: A classic class that defined a __coerce__() method that returned
1066 its arguments swapped would infinitely recurse and segfault the interpreter.
1067
Neal Norwitz909eb122006-06-12 02:13:21 +00001068- Fix the socket tests so they can be run concurrently.
1069
Neal Norwitzb9845e72006-06-12 02:11:18 +00001070- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001071 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001072
Brett Cannon22565aa2006-06-09 22:31:23 +00001073- Bug #532646: object.__call__() will continue looking for the __call__
1074 attribute on objects until one without one is found. This leads to recursion
1075 when you take a class and set its __call__ attribute to an instance of the
1076 class. Originally fixed for classic classes, but this fix is for new-style.
1077 Removes the infinite_rec_3 crasher.
1078
Georg Brandl24250812006-06-09 18:45:48 +00001079- The string and unicode methods startswith() and endswith() now accept
1080 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1081
Brett Cannonde3b0522006-06-08 17:00:45 +00001082- Buffer objects, at the C level, never used the char buffer
1083 implementation even when the char buffer for the wrapped object was
1084 explicitly requested (originally returned the read or write buffer).
1085 Now a TypeError is raised if the char buffer is not present but is
1086 requested.
1087
Georg Brandlddbaa662006-06-04 21:56:52 +00001088- Patch #1346214: Statements like "if 0: suite" are now again optimized
1089 away like they were in Python 2.4.
1090
Georg Brandlb7c8f542006-05-27 12:30:25 +00001091- Builtin exceptions are now full-blown new-style classes instead of
1092 instances pretending to be classes, which speeds up exception handling
1093 by about 80% in comparison to 2.5a2.
1094
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001095- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1096 Unicode 4.1.
1097
Georg Brandlf4ef1162006-05-26 18:03:31 +00001098- Patch #921466: sys.path_importer_cache is now used to cache valid and
1099 invalid file paths for the built-in import machinery which leads to
1100 fewer open calls on startup.
1101
Tim Peters696cf432006-05-24 21:10:40 +00001102- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1103 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1104 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1105 the number of input digits (it was and remains linear-time for bases
1106 2, 4, 8, 16 and 32).
1107
Tim Petersb713ec22006-05-23 18:45:30 +00001108- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1109 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1110 an integer close to ``sys.maxint``. This was repaired by patch
1111 #1335972, which also gives a nice speedup.
1112
Richard Jonescebbefc2006-05-23 18:28:17 +00001113- Patch #1337051: reduced size of frame objects.
1114
1115- PyErr_NewException now accepts a tuple of base classes as its
1116 "base" parameter.
1117
Richard Jones7c88dcc2006-05-23 10:37:38 +00001118- Patch #876206: function call speedup by retaining allocated frame
1119 objects.
1120
Georg Brandl7b90e162006-05-18 07:01:27 +00001121- Bug #1462152: file() now checks more thoroughly for invalid mode
1122 strings and removes a possible "U" before passing the mode to the
1123 C library function.
1124
Neal Norwitz1004a532006-05-15 07:17:23 +00001125- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1126
Neal Norwitz373f0a72006-05-15 07:04:36 +00001127- Bug #1487966: Fix SystemError with conditional expression in assignment
1128
Martin v. Löwis879768d2006-05-11 13:28:43 +00001129- WindowsError now has two error code attributes: errno, which carries
1130 the error values from errno.h, and winerror, which carries the error
1131 values from winerror.h. Previous versions put the winerror.h values
1132 (from GetLastError()) into the errno attribute.
1133
Martin v. Löwis77736712006-05-04 05:51:03 +00001134- Patch #1475845: Raise IndentationError for unexpected indent.
1135
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001136- Patch #1479181: split open() and file() from being aliases for each other.
1137
Tim Peters44bd9862006-06-01 13:49:23 +00001138- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1139 methods were always silently ignored by dictionaries when comparing keys.
1140 They are now passed through (except when using the C API function
1141 ``PyDict_GetItem()``, whose semantics did not change).
1142
1143- Bug #1456209: In some obscure cases it was possible for a class with a
1144 custom ``__eq__()`` method to confuse dict internals when class instances
1145 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1146 No, you don't have any code that did this ;-)

1154
Brett Cannon6ee7d012006-06-08 16:23:04 +00001155- Change binascii.hexlify to accept a read-only buffer instead of only a char
1156 buffer and actually follow its documentation.
1157
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001158- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1159
Nick Coghlanc649ec52006-05-29 12:43:05 +00001160- Patch #1478788 (modified version): The functional extension module has
1161 been renamed to _functools and a functools Python wrapper module added.
1162 This provides a home for additional function related utilities that are
1163 not specifically about functional programming. See PEP 309.
1164
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001165- Patch #1493701: performance enhancements for struct module.

1170 copy() method.
1171
Andrew MacIntyre92913322006-06-13 15:04:24 +00001172- Patch #1454481: thread stack size is now tunable at runtime for thread
1173 enabled builds on Windows and systems with Posix threads support.
1174
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001175- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1176 (up to the system limit of 32K characters).
1177
1178- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1179 As a result, these functions now raise WindowsError instead of OSError.
1180
Tim Peters7a822da2006-05-25 21:50:17 +00001181- ``time.clock()`` on Win64 should use the high-performance Windows
1182 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1183 Windows platforms).
1184
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001185- Calling Tk_Init twice is refused if the first call failed as that
1186 may deadlock.
1187
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001188- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1189 accept it without potentially using an uninitialized pointer.
1190
1191- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1192 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

Gregory P. Smith3c228b12006-06-05 23:59:37 +00001201- bsddb: the __len__ method of a DB object has been fixed to return correct
1202 results. It could previously incorrectly return 0 in some cases.
1203 Fixes SF bug 1493322 (pybsddb bug 1184012).
1204
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001205- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1206 aborts the db transaction safely when a modifier callback fails.
1207 Fixes SF python patch/bug #1408584.
1208
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001209- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001210 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001211 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1212 database calls that would previously deadlock. [SF python bug #775414]

1243
Tim Peters43898b42006-06-14 04:09:25 +00001244- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1245 guarantee that adjacent triples in the return list always describe
1246 non-adjacent blocks. Previously, a pair of matching blocks could end
1247 up being described by multiple adjacent triples that formed a partition
1248 of the matching pair.

1257
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001258- The wsgiref package has been added to the standard library.
1259
Nick Coghlan676725d2006-06-08 13:54:49 +00001260- The functions update_wrapper() and wraps() have been added to the functools
1261 module. These make it easier to copy relevant metadata from the original
1262 function when writing wrapper functions.
1263
Tim Petersd6a9eef2006-06-05 01:48:21 +00001264- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1265 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001266
Martin v. Löwis3f767792006-06-04 19:36:28 +00001267- Patch #1359618: Speed up charmap encoder by using a trie structure
1268 for lookup.
1269
Tim Petersd609b1a2006-06-02 23:22:51 +00001270- The functions in the ``pprint`` module now sort dictionaries by key
1271 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1272 if and only if its display required more than one line, although that
1273 wasn't documented. The new behavior increases predictability; e.g.,
1274 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.

1301 a couple of issues, notably handling of long file names using the
1302 GNU LONGNAME extension.
1303
1304- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1305 new flag when ``name`` is already the name of an option flag.
1306
1307- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1308 package.

1348
1349*Release date: 27-APR-2006*
1350
1351Core and builtins
1352-----------------
1353
Thomas Heller1b046642006-04-18 18:51:06 +00001354- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1355 by converting these apis from macros into exported functions again:
1356
1357 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1358 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1359 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1360 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1361 PyRun_String Py_CompileString
1362
Martin v. Löwis45294a92006-04-18 06:24:08 +00001363- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1364
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001365- All uses of PyStructSequence_InitType have been changed to initialize
1366 the type objects only once, even if the interpreter is initialized
1367 multiple times.
1368
Neal Norwitz61546162006-04-14 05:20:28 +00001369- Bug #1454485, array.array('u') could crash the interpreter. This was
1370 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1371 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1372
1373- Py_UNICODE is unsigned. It was always documented as unsigned, but
1374 due to a bug had a signed value in previous versions.
1375
Tim Peters3a5e8b12006-04-11 01:44:07 +00001376- Patch #837242: ``id()`` of any Python object always gives a positive
1377 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1378 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001379 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001380 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001381
Tim Peters3a5e8b12006-04-11 01:44:07 +00001382 def __hash__(self):
1383 return id(self) # WRONG
1384
1385 because a hash result must be a (short) Python int but it was always
1386 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001387 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001388 was always usable as a hash value before this patch. That's no longer
1389 necessarily so.
1390
1391- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001392 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001393 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001394 #1454844)
1395
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001396- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1397 involving generators that have paused outside of any ``try`` or ``with``
1398 blocks. (In 2.5a1, a paused generator that was part of a reference
1399 cycle could not be garbage collected, regardless of whether it was
1400 paused in a ``try`` or ``with`` block.)

1430 abusing errno.
1431
Tim Peters711bf302006-04-25 03:31:36 +00001432- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1433 a doctest to be skipped (the code is not run, and the expected output
1434 or exception is ignored).
1435
Nick Coghlanda2268f2006-04-24 04:37:15 +00001436- Fixed contextlib.nested to cope with exceptions being raised and
1437 caught inside exit handlers.
1438
Greg Wardab05edc2006-04-23 03:47:58 +00001439- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1440 hex, octal, or binary; add ``append_const`` action; keep going if
1441 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1442 added ``epilog`` for better help generation).
1443
Tim Peters21fbd572006-04-21 21:18:10 +00001444- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1445 called from a thread spawned as a side effect of importing a module.
1446
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001447- The pydoc module now supports documenting packages contained in
1448 .zip or .egg files.
1449
1450- The pkgutil module now has several new utility functions, such
1451 as ``walk_packages()`` to support working with packages that are either
1452 in the filesystem or zip files.
1453
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001454- The mailbox module can now modify and delete messages from
1455 mailboxes, in addition to simply reading them. Thanks to Gregory
1456 K. Johnson for writing the code, and to the 2005 Google Summer of
1457 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001458
Tim Petersc7605f22006-04-17 21:12:33 +00001459- The ``__del__`` method of class ``local`` in module ``_threading_local``
1460 returned before accomplishing any of its intended cleanup.
1461
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001462- Patch #790710: Add breakpoint command lists in pdb.

Tim Peters8931ff12006-05-13 23:28:20 +00001504- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1505 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1506 and "%zu" for unsigned integers of type ``size_t``.
1507

1509-----
1510
Nick Coghlanda2268f2006-04-24 04:37:15 +00001511- test_contextlib now checks contextlib.nested can cope with exceptions
1512 being raised and caught inside exit handlers.
1513
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001514- test_cmd_line now checks operation of the -m and -c command switches
1515
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001516- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1517 it separately and by hand. It also wasn't cleaning up its changes to
1518 the current Decimal context.
1519
Thomas Woutersabd08882006-04-26 15:53:30 +00001520- regrtest.py now has a -M option to run tests that test the new limits of
1521 containers, on 64-bit architectures. Running these tests is only sensible
1522 on 64-bit machines with more than two gigabytes of memory. The argument
1523 passed is the maximum amount of memory for the tests to use.
1524
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001525Tools
1526-----
1527
1528- Added the Python benchmark suite pybench to the Tools/ directory;
1529 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001531Documentation
1532-------------
1533
Tim Petersb06d28c2006-05-12 01:57:59 +00001534- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1535
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001536- PEP 343: Added Context Types section to the library reference
1537 and attempted to bring other PEP 343 related documentation into
1538 line with the implementation and/or python-dev discussions.
1539
Tim Peters8dc73d22006-04-24 02:03:16 +00001540- Bug #1337990: clarified that ``doctest`` does not support examples
1541 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001544What's New in Python 2.5 alpha 1?
1545=================================
1546
Anthony Baxterebed3f62006-04-03 15:03:44 +00001547*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001548
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001549Core and builtins
1550-----------------
1551
Nick Coghlan43832302006-04-23 17:04:07 +00001552- PEP 338: -m command line switch now delegates to runpy.run_module
1553 allowing it to support modules in packages and zipfiles
1554
Martin v. Löwisc661b882006-04-20 04:54:23 +00001555- On Windows, .DLL is not an accepted file name extension for
1556 extension modules anymore; extensions are only found if they
1557 end in .PYD.
1558
Martin v. Löwisea62d252006-04-03 10:56:49 +00001559- Bug #1421664: sys.stderr.encoding is now set to the same value as
1560 sys.stdout.encoding.
1561
Neal Norwitz92e212f2006-04-03 04:48:37 +00001562- __import__ accepts keyword arguments.
1563
Georg Brandlccadf842006-03-31 18:54:53 +00001564- Patch #1460496: round() now accepts keyword arguments.
1565
Anthony Baxter262c00a2006-03-30 10:53:17 +00001566- Fixed bug #1459029 - unicode reprs were double-escaped.
1567
Hye-Shik Changd478f342006-03-23 12:32:36 +00001568- Patch #1396919: The system scope threads are reenabled on FreeBSD
1569 5.4 and later versions.
1570
Neal Norwitze98ccf62006-03-23 05:39:47 +00001571- Bug #1115379: Compiling a Unicode string with an encoding declaration
1572 now gives a SyntaxError.
1573
Georg Brandlabd1ff82006-03-18 07:59:59 +00001574- Previously, Python code had no easy way to access the contents of a
1575 cell object. Now, a ``cell_contents`` attribute has been added
1576 (closes patch #1170323).
1577
Tim Peterscf79aac2006-03-16 01:14:46 +00001578- Patch #1123430: Python's small-object allocator now returns an arena to
1579 the system ``free()`` when all memory within an arena becomes unused
1580 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1581 freed. Some applications will see a drop in virtual memory size now,
1582 especially long-running applications that, from time to time, temporarily
1583 use a large number of small objects. Note that when Python returns an
1584 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001585 platform C library will in turn return that memory to the operating system.
1586 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001587 appears to be effective at least on Microsoft C and gcc-based systems.
1588 Thanks to Evan Jones for hard work and patience.
1589
Georg Brandl533ff6f2006-03-08 18:09:27 +00001590- Patch #1434038: property() now uses the getter's docstring if there is
1591 no "doc" argument given. This makes it possible to legitimately use
1592 property() as a decorator to produce a read-only property.
1593
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001594- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1595 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1596 of requiring an int or long in slicing and a few other contexts, enabling
1597 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1598
Neal Norwitz995acdf2006-03-07 05:01:00 +00001599- Fixed various bugs reported by Coverity's Prevent tool.
1600
Brett Cannonbf364092006-03-01 04:25:17 +00001601- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1602 new exception base class, BaseException, which has a new message attribute.
1603 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1604 Raising a string exception now raises a DeprecationWarning.
1605
Thomas Woutersfb609f42006-02-28 16:37:25 +00001606- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1607 explicitly relative, using 'from .module import name' to mean 'from the same
1608 package as this module is in. Imports without dots still default to the
1609 old relative-then-absolute, unless 'from __future__ import
1610 absolute_import' is used.
1611
Brett Cannona7446e32006-02-27 23:39:10 +00001612- Properly check if 'warnings' raises an exception (usually when a filter set
1613 to "error" is triggered) when raising a warning for raising string
1614 exceptions.
1615
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001616- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001617 The name was removed from Include/code.h.
1618
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001619- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001620
Guido van Rossum1968ad32006-02-25 22:38:04 +00001621- Patch 1433928:
1622 - The copy module now "copies" function objects (as atomic objects).
1623 - dict.__getitem__ now looks for a __missing__ hook before raising
1624 KeyError.
1625
Tim Peters84ef21c2006-02-28 20:39:06 +00001626- PEP 343: with statement implemented. Needs ``from __future__ import
1627 with_statement``. Use of 'with' as a variable will generate a warning.
1628 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001629 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001630 The following objects have __context__ methods:
1631 - The built-in file type.
1632 - The thread.LockType type.
1633 - The following types defined by the threading module:
1634 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1635 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001636
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001637- Fix the encodings package codec search function to only search
1638 inside its own package. Fixes problem reported in patch #1433198.
1639
1640 Note: Codec packages should implement and register their own
1641 codec search function. PEP 100 has the details.
1642
Tim Peters9ea89d22006-06-04 03:26:02 +00001643- PEP 353: Using ``Py_ssize_t`` as the index type.
1644
1645- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1646 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1647 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1648 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1649 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001650
Neal Norwitzfc76d632006-01-10 06:03:13 +00001651- Patch #1400181, fix unicode string formatting to not use the locale.
1652 This is how string objects work. u'%f' could use , instead of .
1653 for the decimal point. Now both strings and unicode always use periods.
1654
Neal Norwitz671b9e32006-01-09 07:07:12 +00001655- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1656 configure would break checking curses.h.
1657
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001658- Bug #959576: The pwd module is now builtin. This allows Python to be
1659 built on UNIX platforms without $HOME set.
1660
Neal Norwitzc10978f2005-12-19 06:07:16 +00001661- Bug #1072182, fix some potential problems if characters are signed.
1662
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001663- Bug #889500, fix line number on SyntaxWarning for global declarations.
1664
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001665- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1666
Neal Norwitze7214a12005-12-18 05:03:17 +00001667- Support for converting hex strings to floats no longer works.
1668 This was not portable. float('0x3') now raises a ValueError.
1669
Barry Warsaw2a38a862005-12-18 01:27:35 +00001670- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001671 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001672 is now displayed in interactive prompt banner.
1673
Georg Brandlfa166682005-12-17 21:45:17 +00001674- Implementation of PEP 341 - Unification of try/except and try/finally.
1675 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001676 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001677
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001678- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1679 now encodes backslash correctly.
1680
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001681- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1682
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001683- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001684 and long longs.
1685
Neal Norwitz67715f02005-11-09 06:59:35 +00001686- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001687 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001688 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001689
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001690- Replaced most Unicode charmap codecs with new ones using the
1691 new Unicode translate string feature in the builtin charmap
1692 codec; the codecs were created from the mapping tables available
1693 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1694 encodings now include a mapping for the Apple logo)
1695
Tim Peterse3547fd2005-12-16 23:13:57 +00001696- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001697
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001698- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001699
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001700- A new AST parser implementation was completed. The abstract
1701 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001702 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001703
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001704- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001705 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1706
Neal Norwitz708e51a2005-10-03 04:48:15 +00001707- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1708
Neal Norwitz11bd1192005-10-03 00:54:56 +00001709- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1710 Provide a warning when a directory is passed on the command line.
1711
Neal Norwitz40d37812005-10-02 01:48:49 +00001712- Fix segfault with invalid coding.
1713
1714- SF bug #772896: unknown encoding results in MemoryError.
1715
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001716- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001717 supported a __len__() method which evaluated to False when the iterator
1718 was empty.
1719
Guido van Rossum630db602005-09-20 18:49:54 +00001720- On 64-bit platforms, when __len__() returns a value that cannot be
1721 represented as a C int, raise OverflowError.
1722
Skip Montanarof8948ca2005-09-19 03:54:46 +00001723- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001724 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001725
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001726- SF bug #893549: parsing keyword arguments was broken with a few format
1727 codes.
1728
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001729- Changes donated by Elemental Security to make it work on AIX 5.3
1730 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1731 bug #105470: test_pwd fails on 64bit system (Opteron).
1732
Guido van Rossum539c6622005-09-14 17:49:54 +00001733- Changes donated by Elemental Security to make it work on HP-UX 11 on
1734 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1735
Georg Brandl4550b8d2005-08-26 06:43:52 +00001736- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001737 (fixes bug #1119418).
1738
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001739- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1740
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001741- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1742 exceptions that cause a function to exit.
1743
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001744- The implementation of set() and frozenset() was revised to use its
1745 own internal data structure. Memory consumption is reduced by 1/3
1746 and there are modest speed-ups as well. The API is unchanged.
1747
Tim Petersde7990b2005-07-17 23:45:23 +00001748- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1749
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001750- SF bug #1229429: PyObject_CallMethod failed to decrement some
1751 reference counts in some error exit cases.
1752
Tim Petersecc6e6a2005-07-10 22:30:55 +00001753- SF bug #1185883: Python's small-object memory allocator took over
1754 a block managed by the platform C library whenever a realloc specified
1755 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001756 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001757 portable way to copy data from the C-managed block into Python's
1758 small-object space without risking a memory fault. Python's small-object
1759 realloc now leaves such blocks under the control of the platform C
1760 realloc.
1761
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001762- SF bug #1232517: An overflow error was not detected properly when
1763 attempting to convert a large float to an int in os.utime().
1764
Raymond Hettinger3296e692005-06-29 23:29:56 +00001765- SF bug #1224347: hex longs now print with lowercase letters just
1766 like their int counterparts.
1767
Michael W. Hudson188d4362005-06-20 16:52:57 +00001768- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1769 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1770 interpreter states; back out that fix and do a better job (see
1771 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1772 for a longer write-up of the problem).
1773
Michael W. Hudsondf888462005-06-03 14:41:55 +00001774- SF patch #1180995: marshal now uses a binary format by default when
1775 serializing floats.
1776
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001777- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1778 the routines that promise to produce IEEE 754 binary representations
1779 of floats now simply copy bytes around.
1780
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001781- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1782 278.
1783
Brett Cannonc3647ac2005-04-26 03:45:26 +00001784- patch #1109424: int, long, float, complex, and unicode now check for the
1785 proper magic slot for type conversions when subclassed. Previously the
1786 magic slot was ignored during conversion. Semantics now match the way
1787 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001788 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001789 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001790 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001791
Barry Warsawc8d907c2005-04-19 23:43:40 +00001792- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1793 NULL, now raise an AttributeError when attempting to set or delete the
1794 attribute. Previously a TypeError was raised, but this was inconsistent
1795 with the equivalent pure-Python implementation.
1796
Michael W. Hudson774479c2005-04-18 08:46:17 +00001797- It is now safe to call PyGILState_Release() before
1798 PyEval_InitThreads() (note that if there is reason to believe there
1799 are multiple threads around you still must call PyEval_InitThreads()
1800 before using the Python API; this fix is for extension modules that
1801 have no way of knowing if Python is multi-threaded yet).
1802
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001803- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1804 disabled caused a crash.
1805
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001806- Bug #1165306: instancemethod_new allowed the creation of a method
1807 with im_class == im_self == NULL, which caused a crash when called.
1808
Tim Petersecc6e6a2005-07-10 22:30:55 +00001809- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001810 fixes the crash seen in bug #1165761
1811
Raymond Hettinger96229b12005-03-11 06:49:40 +00001812- Added two new builtins, any() and all().
1813
Brett Cannon409d8f22005-03-05 06:47:57 +00001814- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001815 (e.g., ``class C(): pass`` is no longer a syntax error).
1816 Patch #1176012 added support to the 'parser' module and 'compiler' package
1817 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001818
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001819- Patch #1115086: Support PY_LONGLONG in structmember.
1820
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001821- Bug #1155938: new style classes did not check that __init__() was
1822 returning None.
1823
Tim Petersecc6e6a2005-07-10 22:30:55 +00001824- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001825 ('\') with a specific error message.
1826
Martin v. Löwisff232d72005-03-03 09:24:38 +00001827- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1828
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001829- Bug #1124295: the __name__ attribute of file objects was
1830 inadvertently made inaccessible in restricted mode.
1831
Tim Petersecc6e6a2005-07-10 22:30:55 +00001832- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001833 an ferror() call.
1834
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001835- min() and max() now support key= arguments with the same meaning as in
1836 list.sort().
1837
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001838- The peephole optimizer now performs simple constant folding in expressions:
1839 (2+3) --> (5).
1840
Raymond Hettingera422c342005-01-11 03:03:27 +00001841- set and frozenset objects can now be marshalled. SF #1098985.
1842
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001843- Bug #1077106: Poor argument checking could cause memory corruption
1844 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001845
Jeremy Hyltonab630502005-02-04 18:44:06 +00001846- The parser did not complain about future statements in illegal
1847 positions. It once again reports a syntax error if a future
1848 statement occurs after anything other than a doc string.
1849
Neil Schemenauercf52c072005-08-12 17:34:58 +00001850- Change the %s format specifier for str objects so that it returns a
1851 unicode instance if the argument is not an instance of basestring and
1852 calling __str__ on the argument returns a unicode instance.
1853
Tim Petersf4e69282006-02-27 17:15:31 +00001854- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1855 current thread state when the auto-GIL-state machinery knows about
1856 it (since the thread state is being deleted, continuing to remember it
1857 can't help, but can hurt if another thread happens to get created with
1858 the same thread id).
1859

1888 for applications that require this specific version (such as IDNA).
1889
Neal Norwitzb62c4332006-03-04 18:35:47 +00001890- The timing module is no longer built by default. It was deprecated

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002050- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2051 been renamed to have only a single underscore prefix. This was done to
2052 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002053
Nick Coghlan43832302006-04-23 17:04:07 +00002054- PEP 338: new module runpy defines a run_module function to support
2055 executing modules which provide access to source code or a code object
2056 via the PEP 302 import mechanisms.
2057
Anthony Baxter93f5b932006-04-03 08:05:07 +00002058- The email module's parsedate_tz function now sets the daylight savings

2066 in attribute values.
2067
Anthony Baxterc51ee692006-04-01 00:57:31 +00002068- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002069 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002070 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002071 module will not be built.
2072
Tim Petersc17976e2006-04-01 00:26:53 +00002073- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2074 aren't officially supported here, and trying to use them will probably
2075 raise an exception some day. But dicts have been allowed, and "mostly
2076 worked", so support for them won't go away without warning.
2077
Georg Brandl338ef7d2006-03-31 18:42:16 +00002078- Bug #1445068: getpass.getpass() can now be given an explicit stream

2096
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002097- email 4.0 package now integrated. This is largely the same as the email 3.0
2098 package that was included in Python 2.3, except that PEP 8 module names are
2099 now used (e.g. mail.message instead of email.Message). The MIME classes
2100 have been moved to a subpackage (e.g. email.mime.text instead of
2101 email.MIMEText). The old names are still supported for now. Several
2102 deprecated Message methods have been removed and lots of bugs have been
2103 fixed. More details can be found in the email package documentation.
2104
Walter Dörwald40108c92006-03-27 08:15:44 +00002105- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2106 (a subclass of tuple) that provides incremental decoders and encoders
2107 (a way to use stateful codecs without the stream API). Python functions
2108 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2109 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2110 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002111
Walter Dörwald067db482006-03-15 22:17:27 +00002112- Patch #1359365: Calling next() on a closed StringIO.String object raises
2113 a ValueError instead of a StopIteration now (like file and cString.String do).
2114 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2115 called before (like file and StringIO.StringIO do).

2190 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2191 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2192 Ronald L. Rivest offered this advice for Python:
2193
2194 "The consensus of researchers in this area (at least as
2195 expressed at the NIST Hash Function Workshop 10/31/05),
2196 is that SHA-256 is a good choice for the time being, but
2197 that research should continue, and other alternatives may
2198 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002199
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002200- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandl9166e1a2005-06-04 09:20:03 +00002300- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2301
Georg Brandl268e61c2005-06-03 14:28:50 +00002302- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2303 component of the path.
2304
Skip Montanaro174dd222005-05-14 20:54:16 +00002305- Patch #1120353: The xmlrpclib module provides better, more transparent,
2306 support for datetime.{datetime,date,time} objects. With use_datetime set
2307 to True, applications shouldn't have to fiddle with the DateTime wrapper
2308 class at all.
2309
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002310- distutils.commands.upload was added to support uploading distribution
2311 files to PyPI.
2312
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002313- distutils.commands.register now encodes the data as UTF-8 before posting
2314 them to PyPI.
2315
Raymond Hettinger267b8682005-03-27 10:47:39 +00002316- decimal operator and comparison methods now return NotImplemented
2317 instead of raising a TypeError when interacting with other types. This
2318 allows other classes to implement __radd__ style methods and have them
2319 work as expected.
2320
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002321- Bug #1163325: Decimal infinities failed to hash. Attempting to
2322 hash a NaN raised an InvalidOperation instead of a TypeError.
2323
Tim Petersecc6e6a2005-07-10 22:30:55 +00002324- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002325 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2326
Martin v. Löwis00a73e72005-03-04 19:40:34 +00002327- Patch #1043890: Add extractall method to tarfile.

2330 to build.
2331
Martin v. Löwis637431b2005-03-03 23:12:42 +00002332- Patch #1103407: Properly deal with tarfile iterators when untarring
2333 symbolic links on Windows.
2334

Martin v. Löwisa4dac402005-03-03 11:39:45 +00002336 profile.py if available.
2337
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00002338- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
2339
Martin v. Löwisc5574e82005-03-03 10:57:37 +00002340- Patch #1117454: Remove code to special-case cookies without values
2341 in LWPCookieJar.
2342
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00002343- Patch #1117339: Add cookielib special name tests.
2344

2346
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00002347- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
2348
Martin v. Löwisdf241532005-03-03 08:17:42 +00002349- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
2350
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00002351- Patch #1104111: Alter setup.py --help and --help-commands.
2352
Martin v. Löwis4afe1542005-03-01 08:09:28 +00002353- Patch #1121234: Properly cleanup _exit and tkerror commands.
2354
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00002355- Patch #1049151: xdrlib now unpacks booleans as True or False.
2356
Raymond Hettingerbab41432005-02-05 01:31:19 +00002357- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2358
Guido van Rossumd0641422005-02-03 15:01:24 +00002359- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2360 disables recursive traversal through instance attributes, which can
2361 be exploited in various ways.
2362
Tim Peterse3547fd2005-12-16 23:13:57 +00002363- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002364 flags on the HTTP listening socket.
2365
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002366- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2367 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2368
Fred Drakefbdeaad2006-07-29 16:56:15 +00002369- Patches #893642, #1039083: add allow_none, encoding arguments to
2370 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002371
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002372- Bug #1110478: Revert os.environ.update to do putenv again.
2373
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002374- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2375
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002376- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2377
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002378- Enhancements to the csv module:
2379
2380 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002381 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002382 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002383 + Dialect parameter parsing has been re-implemented to improve error
2384 reporting.
2385 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2386 dictates.
2387 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002388 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002389 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002390 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2391 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002392 + reader now allows \r characters to be quoted (previously it only allowed
2393 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002394 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002395 + Dialect classes passed to the module are no longer instantiated by
2396 the module before being parsed (the former validation scheme required
2397 this, but the mechanism was unreliable).
2398 + The dialect registry now contains instances of the internal
2399 C-coded dialect type, rather than references to python objects.
2400 + the internal c-coded dialect type is now immutable.
2401 + register_dialect now accepts the same keyword dialect specifications
2402 as the reader and writer, allowing the user to register dialects
2403 without first creating a dialect class.
2404 + a configurable limit to the size of parsed fields has been added -
2405 previously, an unmatched quote character could result in the entire
2406 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002407 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002408 the parser field size limit (returning the former limit). The initial
2409 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002410 + A line_num attribute has been added to the reader object, which tracks
2411 the number of lines read from the source iterator. This is not
2412 the same as the number of records returned, as records can span
2413 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002414 + reader and writer objects were not being registered with the cyclic-GC.
2415 This has been fixed.
2416
Brett Cannone6539c42005-01-08 02:43:53 +00002417- _DummyThread objects in the threading module now delete self.__block that is
2418 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2419 lock primitives tend to be limited in number and thus should not be wasted on
2420 a _DummyThread object. Fixes bug #1089632.
2421
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002422- The imghdr module now detects Exif files.
2423
Raymond Hettinger6065d322004-12-20 23:51:53 +00002424- StringIO.truncate() now correctly adjusts the size attribute.
2425 (Bug #951915).
2426
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002427- locale.py now uses an updated locale alias table (built using
2428 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2429 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002430 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002431
Raymond Hettinger3557f422004-12-07 12:02:02 +00002432- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2433
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002434- the pickle module no longer accepts the deprecated None option in the
2435 args tuple returned by __reduce__().
2436
Brett Cannon84667c02004-12-07 03:25:18 +00002437- optparse now optionally imports gettext. This allows its use in setup.py.
2438
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002439- the pickle module no longer uses the deprecated bin parameter.
2440
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002441- the shelve module no longer uses the deprecated binary parameter.
2442
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002443- the pstats module no longer uses the deprecated ignore() method.
2444
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002445- the filecmp module no longer uses the deprecated use_statcache argument.
2446
Raymond Hettinger664347b2004-12-04 21:21:53 +00002447- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2448 extended or overridden by subclasses. Formerly, the subclassed method would
2449 be ignored by the rest of the module. (Bug #1078905).
2450
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002451- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002452 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002453
Walter Dörwald36733692004-12-22 12:50:50 +00002454- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2455 once when a size argument is given. This prevents a buffer overflow in the
2456 tokenizer with very long source lines.
2457
Barry Warsaw538561e2006-01-01 21:48:54 +00002458- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2459 immediately after creating the object, without any intervening
2460 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002461
Skip Montanaro05885812005-01-16 20:48:27 +00002462- The reconvert.quote function can now emit triple-quoted strings. The
2463 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002464
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002465- ``UserString.MutableString`` now supports negative indices in
2466 ``__setitem__`` and ``__delitem__``
2467
Greg Ward40407942005-03-05 02:53:17 +00002468- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2469 correctly.
2470
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002471- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2472 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2473 character even if the user has passed a size parameter to get a proper
2474 line ending. Remove the special handling of a "\r\n" that has been split
2475 between two lines.
2476
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002477- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2478 about illegal code points. The codec now supports PEP 293 style error
2479 handlers.
2480
Walter Dörwald78a78b02005-09-01 12:04:29 +00002481- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002482 from the input stream, so that the output is a byte string in the correct
2483 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002484
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002485- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2486 considering it exactly like a '*'.
2487
Walter Dörwald007f8df2005-10-09 19:42:27 +00002488- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2489 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002490
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002491- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2492
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002493- Patch #1413711: Certain patterns of differences were making difflib
2494 touch the recursion limit.
2495
Walter Dörwald58917a62006-03-31 15:26:22 +00002496- Bug #947906: An object oriented interface has been added to the calendar
2497 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002498 called as a script (e.g. via ``python -mcalendar``). Localized month and
2499 weekday names can be ouput (even if an exotic encoding is used) using
2500 special classes that use unicode.

2503-----
2504
Neal Norwitz602d3392006-03-31 08:21:40 +00002505- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2506 by using -mieee gcc option.
2507
Martin v. Löwis86d66262006-02-17 08:40:11 +00002508- Patch #1432345: Make python compile on DragonFly.
2509
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002510- Build support for Win64-AMD64 was added.
2511
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002512- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2513
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002514- Patch #881820: look for openpty and forkpty also in libbsd.
2515
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002516- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2517 The zlib module is now builtin on Windows.
2518
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002519- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2520
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002521- Bug #1189330: configure did not correctly determine the necessary
2522 value of LINKCC if python was built with GCC 4.0.
2523
Trent Mick8321b422005-07-26 02:29:21 +00002524- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2525 vulnerability in zlib 1.2.1 and 1.2.2.
2526
Brett Cannon08cd5982005-04-24 22:26:38 +00002527- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2528 flags that change binary compatibility. Changes were also made to
2529 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002530 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002531
Bob Ippolitoed233462005-03-29 13:47:59 +00002532- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2533 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2534 no longer exists). This configure patch makes things right.
2535
Martin v. Löwise2713be2005-03-08 15:03:08 +00002536- Bug #1158607: Build with --disable-unicode again.
2537
Brett Cannon46d96232005-02-16 00:07:19 +00002538- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2539 defined. Discovered as a result of not being able to build on OS X.
2540
Brett Cannon516592f2004-12-07 00:42:59 +00002541- setup.py now uses the directories specified in LDFLAGS using the -L option
2542 and in CPPFLAGS using the -I option for adding library and include
2543 directories, respectively, for compiling extension modules against. This has
2544 led to the core being compiled using the values in CPPFLAGS. It also removes
2545 the need for the special-casing of both DarwinPorts and Fink for darwin since
2546 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2547 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2548 Fink, ``-I/opt/local/include`` for DarwinPorts).
2549
Brett Cannon43802422005-02-10 20:48:03 +00002550- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2551 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2552 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2553 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002555C API
2556-----
2557
Tim Petersc9d78aa2006-03-26 23:27:58 +00002558- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2559 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2560 is obtained via the ``PyObject_`` family, it must be released via the
2561 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2562 always been officially true, but when Python's small-object allocator was
2563 introduced, an attempt was made to cater to a few extension modules
2564 discovered at the time that obtained memory via ``PyObject_New`` but
2565 released it via ``PyMem_DEL``. It's years later, and if such code still
