101
Brett Cannon9adeab72006-09-20 18:34:28 +0000102- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
103 allows calling unicode() on exceptions classes directly to succeed.
104
Georg Brandlec6c2df2006-09-11 09:38:35 +0000105- Make _PyGILState_NoteThreadState() static, it was not used anywhere

123 head is the original string if sep was not found.
124
Neal Norwitzdac090d2006-09-05 03:53:08 +0000125- Bug #1520864: unpacking singleton tuples in list comprehensions and
126 generator expressions (x for x, in ... ) works again. Fixing this problem
127 required changing the .pyc magic number. This means that .pyc files
128 generated before 2.5c2 will be regenerated.

Jeremy Hyltoncca75402007-02-27 18:33:31 +0000134- Add new requirements for metaclasses. 1) If type or a subclass of type
135 occurs in __bases__, it must occur before any non-type bases, e.g.
136 before regular classes. 2) If you assign to __bases__, you may not
137 change the metaclass. Many more illegal assignments to __bases__
138 are now checked and raise TypeErrors. This changed fixed at least
139 one known crash.

597 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000598
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000599 Instead, the equal (==) and unequal (!=) comparison operators will
600 now issue a UnicodeWarning and interpret the two objects as
601 unequal. The UnicodeWarning can be filtered as desired using
602 the warning framework, e.g. silenced completely, turned into an
603 exception, logged, etc.
604
605 Note that compare operators other than equal and unequal will still
606 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000607
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000608- Fix segfault when doing string formatting on subclasses of long.
609
610- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
611 with new-style classes.
612
613- Fix bug related to __len__ functions returning negative values with
614 classic classes.
615
616- Patch #1538606, Fix __index__() clipping. There were some problems
617 discovered with the API and how integers that didn't fit into Py_ssize_t
618 were handled. This patch attempts to provide enough alternatives
619 to effectively use __index__.
620
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000621- Bug #1536021: __hash__ may now return long int; the final hash
622 value is obtained by invoking hash on the long int.
623
Thomas Hellerab1049c2006-08-08 17:37:00 +0000624- Bug #1536786: buffer comparison could emit a RuntimeWarning.
625
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000626- Bug #1535165: fixed a segfault in input() and raw_input() when
627 sys.stdin is closed.
628
Thomas Heller74d36f02006-08-04 18:17:40 +0000629- On Windows, the PyErr_Warn function is now exported from
630 the Python dll again.
631
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000632- Bug #1191458: tracing over for loops now produces a line event
633 on each iteration. Fixing this problem required changing the .pyc
634 magic number. This means that .pyc files generated before 2.5c1
635 will be regenerated.
636
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000637- Bug #1333982: string/number constants were inappropriately stored
638 in the byte code and co_consts even if they were not used, ie
639 immediately popped off the stack.
640
Georg Brandle9462c72006-08-04 18:03:37 +0000641- Fixed a reference-counting problem in property().

644Library
645-------
646
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000647- Fix a bug in the ``compiler`` package that caused invalid code to be
648 generated for generator expressions.
649
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000650- The distutils version has been changed to 2.5.0. The change to
651 keep it programmatically in sync with the Python version running
652 the code (introduced in 2.5b3) has been reverted. It will continue
653 to be maintained manually as static string literal.
654
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000655- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000656 and this cannot be converted to the required C type, an exception is
657 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000658 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000659
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000660- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000661 an exception.
662
Tim Petersc10c9d02006-09-05 02:18:09 +0000663- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000664 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000665 workarounds for clocks with low resolution, to stop the code yielding
666 duplicate UUIDs.
667
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000668- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
669 before raising SystemExit, allowing IDLE to honor quit() and exit().
670
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000671- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
672
Georg Brandl7a1af772006-08-14 21:55:28 +0000673- Patch #1536071: trace.py should now find the full module name of a
674 file correctly even on Windows.
675
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000676- logging's atexit hook now runs even if the rest of the module has
677 already been cleaned up.
678
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000679- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000680
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000681- Bug #1531405, format_exception no longer raises an exception if
682 str(exception) raised an exception.
683
Neil Schemenauer06ded092006-08-04 16:20:30 +0000684- Fix a bug in the ``compiler`` package that caused invalid code to be
685 generated for nested functions.

694 raises the correct exceptions.
695
Thomas Heller1ce433e2006-08-14 16:20:04 +0000696- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
697 '-no-stack-protector' compiler flag for OpenBSD has been removed.
698
Thomas Heller86720042006-08-14 11:17:48 +0000699- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
700 uses the _as_parameter_ attribute when objects are passed to foreign
701 function calls. The ctypes version number was changed to 1.0.1.
702
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000703- Bug #1530559, struct.pack raises TypeError where it used to convert.
704 Passing float arguments to struct.pack when integers are expected
705 now triggers a DeprecationWarning.

Georg Brandl9908d162006-08-06 07:06:33 +0000716- Bug #1535182: really test the xreadlines() method of bz2 objects.
717
Andrew MacIntyre16ee33a2006-08-06 12:37:03 +0000718- test_threading now skips testing alternate thread stack sizes on
719 platforms that don't support changing thread stack size.

729-----
730
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +0000731- Bug #1535502, build _hashlib on Windows, and use masm assembler
732 code in OpenSSL.
733
Thomas Hellerdb7b4432006-08-04 19:49:31 +0000734- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

Tim Peters4643c2f2006-08-10 22:45:34 +0000739C API
740-----
741
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000742- New API for Unicode rich comparisons: PyUnicode_RichCompare()
743
Tim Peters4643c2f2006-08-10 22:45:34 +0000744- Bug #1069160. Internal correctness changes were made to
745 ``PyThreadState_SetAsyncExc()``. A test case was added, and
746 the documentation was changed to state that the return value
747 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +0000750What's New in Python 2.5 beta 3?
751================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000752
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000753*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000754
755Core and builtins
756-----------------
757
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000758- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000759 returned a long (see PEP 353).
760
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000761- Bug #1515471: string.replace() accepts character buffers again.
762
Neal Norwitz07aadb12006-07-30 06:55:48 +0000763- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
764 This provides the proper warning for struct.pack().
765 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
766
Neal Norwitz0d62a062006-07-30 06:53:31 +0000767- Patch #1531113: Fix augmented assignment with yield expressions.
768 Also fix a SystemError when trying to assign to yield expressions.
769
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000770- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
771 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
772 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
773 excessive filesystem operations during imports.
774
Tim Petersbc24eee2006-07-27 01:14:53 +0000775- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
776 operations on signed longs that are formally undefined by C.
777 Unfortunately, at least one compiler now cares about that, so complicated
778 the code to make that compiler happy again.
779
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000780- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
781
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000782- Patch #1232023: Stop including current directory in search
783 path on Windows.
784
Neal Norwitze1fdb322006-07-21 05:32:28 +0000785- Fix some potential crashes found with failmalloc.
786
Neal Norwitze7563102006-07-17 01:00:16 +0000787- Fix warnings reported by Klocwork's static analysis tool.
788
Neal Norwitz84be93b2006-07-16 01:50:38 +0000789- Bug #1512814, Fix incorrect lineno's when code within a function
790 had more than 255 blank lines.
791
Georg Brandl9dceedb2006-07-12 15:31:17 +0000792- Patch #1521179: Python now accepts the standard options ``--help`` and
793 ``--version`` as well as ``/?`` on Windows.
794
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000795- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000796 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000797 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000798
Tim Peters112aad32006-07-19 00:03:19 +0000799- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000800 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000801 new ``sys._current_frames()`` returns a dictionary with one entry,
802 mapping the faux "thread id" 0 to the current frame.
803
Ronald Oussoren3075e162006-07-25 20:28:55 +0000804- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000805
Ronald Oussoren3075e162006-07-25 20:28:55 +0000806
Neal Norwitza1f10902006-07-12 07:28:29 +0000807Library
808-------
809
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000810- Correction of patch #1455898: In the mbcs decoder, set final=False
811 for stream decoder, but final=True for the decode function.
812
Georg Brandl07fec3a2006-08-01 18:49:24 +0000813- os.urandom no longer masks unrelated exceptions like SystemExit or
814 KeyboardInterrupt.
815
Tim Peters4643c2f2006-08-10 22:45:34 +0000816- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000817 shutil.copytree on Windows
818
Georg Brandle34ac7c2006-07-30 11:07:23 +0000819- Bug #1002398: The documentation for os.path.sameopenfile now correctly
820 refers to file descriptors, not file objects.
821
Tim Petersc10c9d02006-09-05 02:18:09 +0000822- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000823 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000824 #1513611, and probably others.
825
Georg Brandledd9b0d2006-07-29 09:33:26 +0000826- Bug #1441397: The compiler module now recognizes module and function
827 docstrings correctly as it did in Python 2.4.
828
Tim Peters6f681472006-07-27 23:44:37 +0000829- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
830 lost that tests are sorted by name before being run. This rarely
831 matters for well-written tests, but can create baffling symptoms if
832 side effects from one test to the next affect outcomes. ``DocTestFinder``
833 has been changed to sort the list of tests it returns.
834
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000835- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000836 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000837
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000838- Bug #978833: Really close underlying socket in _socketobject.close.
839
Georg Brandl8c036cc2006-08-20 13:15:39 +0000840- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
841 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000842
Georg Brandlcf0c1722006-07-26 07:23:32 +0000843- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
844 to recursive calls and call it with the failing package name.
845
Martin v. Löwis0b483032006-07-25 09:53:12 +0000846- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
847
Georg Brandlc13c34c2006-07-24 14:09:56 +0000848- Patch #1515343: Fix printing of deprecated string exceptions with a
849 value in the traceback module.
850
Greg Ward48fae7a2006-07-23 16:05:51 +0000851- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
852
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000853- Patch #1524429: Use repr() instead of backticks in Tkinter again.
854
Brett Cannoncaebe222006-07-18 04:41:36 +0000855- Bug #1520914: Change time.strftime() to accept a zero for any position in its
856 argument tuple. For arguments where zero is illegal, the value is forced to
857 the minimum value that is correct. This is to support an undocumented but
858 common way people used to fill in inconsequential information in the time
859 tuple pre-2.4.
860
Bob Ippolito5ea4bf12006-07-15 16:53:15 +0000861- Patch #1220874: Update the binhex module for Mach-O.
862
Barry Warsawb110bad2006-07-21 14:51:07 +0000863- The email package has improved RFC 2231 support, specifically for
864 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
865 (name*0=<blah>) parameter continuations. This may change the types of
866 values returned from email.message.Message.get_param() and friends.
867 Specifically in some cases where non-encoded continuations were used,
868 get_param() used to return a 3-tuple of (None, None, string) whereas now it
869 will just return the string (since non-encoded continuations don't have
870 charset and language parts).
871
872 Also, whereas % values were decoded in all parameter continuations, they are
873 now only decoded in encoded parameter parts.
874
Ronald Oussoren3075e162006-07-25 20:28:55 +0000875- Bug #1517990: IDLE keybindings on MacOS X now work correctly
876
877- Bug #1517996: IDLE now longer shows the default Tk menu when a
878 path browser, class browser or debugger is the frontmost window on MacOS X
879
Barry Warsaw00decd72006-07-27 23:43:15 +0000880- Patch #1520294: Support for getset and member descriptors in types.py,
881 inspect.py, and pydoc.py. Specifically, this allows for querying the type
882 of an object against these built-in types and more importantly, for getting
883 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitz9b0ca792006-08-02 06:46:21 +0000889- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
890 a socket operation on a socket with a timeout, the exception will be
891 caught correctly. Previously, the exception was not caught.
892
Thomas Heller1393d6a2006-07-28 21:43:20 +0000893- Patch #1529514: The _ctypes extension is now compiled on more
894 openbsd target platforms.
895
Tim Peters9cab5932006-07-28 00:30:00 +0000896- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
897 a memory leak, affecting pickles and deep copies.
898
Tim Petersbc24eee2006-07-27 01:14:53 +0000899- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +0000900 Paul Eggert.
901
Martin v. Löwisbda0dde2006-07-24 10:26:33 +0000902- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
903
Thomas Hellerce049a02006-07-14 17:51:14 +0000904- Patch #1521817: Index range checking on ctypes arrays containing
905 exactly one element enabled again. This allows iterating over these
906 arrays, without the need to check the array size before.
907
Thomas Heller6e1ad2e2006-07-13 17:05:13 +0000908- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +0000909 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +0000910 /dev/null in certain cases; this is now fixed.
911
Thomas Heller47d7a062006-07-12 08:43:47 +0000912- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
913 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +0000914
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +0000915- Because of a misspelled preprocessor symbol, ctypes was always
916 compiled without thread support; this is now fixed.
917
Gregory P. Smith641cddf2006-07-28 01:35:25 +0000918- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
919 methods now allow their database parameter to be None as the
920 sleepycat API allows.
921
Matt Flemingec926502006-07-28 11:27:27 +0000922- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
923 bluetooth API compared with Linux and FreeBSD.
924
Brett Cannonf23ad3d2006-07-25 17:32:20 +0000925Tests
926-----
927
928- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
929 how long the test file should take to play. Now accepts taking 2.93 secs
930 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
931
Georg Brandl4793aa32006-07-28 18:31:39 +0000932- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
933 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
934 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +0000935
Martin v. Löwis0907f4d2006-07-30 14:09:47 +0000936Build

938
939- Bug #1439538: Drop usage of test -e in configure as it is not portable.
940
Ronald Oussoren26cad082006-08-01 21:00:57 +0000941Mac
942---
943
944- PythonLauncher now works correctly when the path to the script contains
945 characters that are treated specially by the shell (such as quotes).
946
947- Bug #1527397: PythonLauncher now launches scripts with the working directory
948 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +0000949 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +0000950 expect.

Georg Brandlad29e632006-06-21 17:45:17 +0000957
958Core and builtins
959-----------------
960
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +0000961- Bug #1441486: The literal representation of -(sys.maxint - 1)
962 again evaluates to a int object, not a long.
963
Neil Schemenauer0e07b602006-07-09 16:16:34 +0000964- Bug #1501934: The scope of global variables that are locally assigned
965 using augmented assignment is now correctly determined.
966
Martin v. Löwisd5cfa542006-07-03 13:47:40 +0000967- Bug #927248: Recursive method-wrapper objects can now safely
968 be released.
969
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +0000970- Bug #1417699: Reject locale-specific decimal point in float()
971 and atof().
972
Hye-Shik Change6a1cb92006-06-23 21:16:18 +0000973- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
974 omit a default "error" argument for NULL pointer. This allows
975 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +0000976
Neal Norwitzfb48afa2006-07-08 05:31:37 +0000977- Bug #1519018: 'as' is now validated properly in import statements.
978
Neal Norwitz28746ab2006-07-09 22:14:42 +0000979- On 64 bit systems, int literals that use less than 64 bits are
980 now ints rather than longs.
981
Neal Norwitzed657552006-07-10 00:04:44 +0000982- Bug #1512814, Fix incorrect lineno's when code at module scope
983 started after line 256.
984
Tim Peters32a83612006-07-10 21:08:24 +0000985- New function ``sys._current_frames()`` returns a dict mapping thread
986 id to topmost thread stack frame. This is for expert use, and is
987 especially useful for debugging application deadlocks. The functionality
988 was previously available in Fazal Majid's ``threadframe`` extension
989 module, but it wasn't possible to do this in a wholly threadsafe way from
990 an extension.
991

999
Tim Peters32a83612006-07-10 21:08:24 +00001000- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001001 environment variable to be set in order to the SDK environment
1002 for finding the compiler, include files, etc.

Nick Coghlan2d792252006-07-06 13:47:18 +00001006- warnings.py now ignores ImportWarning by default
1007
Thomas Woutersadd19112006-07-05 11:03:49 +00001008- string.Template() now correctly handles tuple-values. Previously,
1009 multi-value tuples would raise an exception and single-value tuples would
1010 be treated as the value they contain, instead.
1011
Martin v. Löwisede77f52006-07-03 13:01:35 +00001012- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1014
Martin v. Löwis45482392006-07-03 12:28:58 +00001015- Bug #1267547: Put proper recursive setup.py call into the
1016 spec file generated by bdist_rpm.
1017
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001018- Bug #1514693: Update turtle's heading when switching between
1019 degrees and radians.
1020
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001021- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001022 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001023
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001024- Bug #1514703: Only setup canvas window in turtle when the canvas
1025 is created.
1026
Martin v. Löwis7596e832006-07-01 15:33:37 +00001027- Bug #1513223: .close() of a _socketobj now releases the underlying
1028 socket again, which then gets closed as it becomes unreferenced.

1031 attribute values.
1032
1033- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1034 sgmllib ('[' and ']' were not accepted).
1035
Georg Brandl1be63af2006-06-28 20:23:25 +00001036- Fix a bug in the turtle module's end_fill function.
1037
Brett Cannon53ab5b72006-06-22 16:49:14 +00001038- Bug #1510580: The 'warnings' module improperly required that a Warning
1039 category be either a types.ClassType and a subclass of Warning. The proper
1040 check is just that it is a subclass with Warning as the documentation states.
1041
Georg Brandlad29e632006-06-21 17:45:17 +00001042- The compiler module now correctly compiles the new try-except-finally
1043 statement (bug #1509132).
1044
Neal Norwitz60373cd2006-06-22 06:30:50 +00001045- The wsgiref package is now installed properly on Unix.
1046
Vinay Sajip28e57612006-07-01 10:45:20 +00001047- A bug was fixed in logging.config.fileConfig() which caused a crash on
1048 shutdown when fileConfig() was called multiple times.
1049
Gerhard Häring762fbd32006-07-02 17:48:30 +00001050- The sqlite3 module did cut off data from the SQLite database at the first
1051 null character before sending it to a custom converter. This has been fixed
1052 now.
1053
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001054Extension Modules
1055-----------------
1056
Tim Peters112aad32006-07-19 00:03:19 +00001057- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1058 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1059 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001060
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001061- Assigning None to pointer type fields in ctypes structures possible
1062 overwrote the wrong fields, this is fixed now.
1063
1064- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1065 on non-Windows platforms.
1066
1067- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1068 integer or long, without range checking.
1069
1070- Patch #1517790: It is now possible to use custom objects in the ctypes
1071 foreign function argtypes sequence as long as they provide a from_param
1072 method, no longer is it required that the object is a ctypes type.
1073
1074- The '_ctypes' extension module now works when Python is configured
1075 with the --without-threads option.
1076
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001077- Bug #1513646: os.access on Windows now correctly determines write
1078 access, again.
1079
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001080- Bug #1512695: cPickle.loads could crash if it was interrupted with
1081 a KeyboardInterrupt.
1082
Neal Norwitza12aa882006-07-06 06:45:08 +00001083- Bug #1296433: parsing XML with a non-default encoding and
1084 a CharacterDataHandler could crash the interpreter in pyexpat.
1085
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001086- Patch #1516912: improve Modules support for OpenVMS.
1087
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001088Build
1089-----
1090
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001091- Automate Windows build process for the Win64 SSL module.
1092
Tim Peters32a83612006-07-10 21:08:24 +00001093- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001094 Previously, the slight difference could cause compilation errors of the
1095 'zlib' module on systems with more than one version of zlib.
1096
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001097- The MSI compileall step was fixed to also support a TARGETDIR
1098 with spaces in it.
1099
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001100- Bug #1517388: sqlite3.dll is now installed on Windows independent
1101 of Tcl/Tk.
1102
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001103- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001104 trying to be installed even though it's empty.

1108
1109- Call os.waitpid() at the end of tests that spawn child processes in order
1110 to minimize resources (zombies).
1111
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001112Documentation
1113-------------
1114
Nick Coghlan2d792252006-07-06 13:47:18 +00001115- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1116 documentation for the warnings module.
1117
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001118- Patch #1509163: MS Toolkit Compiler no longer available.
1119

1128Core and builtins
1129-----------------
1130
Georg Brandla56b9152006-06-19 06:35:54 +00001131- Patch #1507676: Error messages returned by invalid abstract object operations
1132 (such as iterating over an integer) have been improved and now include the
1133 type of the offending object to help with debugging.
1134
Brett Cannonea3912b2006-06-13 21:46:41 +00001135- Bug #992017: A classic class that defined a __coerce__() method that returned
1136 its arguments swapped would infinitely recurse and segfault the interpreter.
1137
Neal Norwitz909eb122006-06-12 02:13:21 +00001138- Fix the socket tests so they can be run concurrently.
1139
Neal Norwitzb9845e72006-06-12 02:11:18 +00001140- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001141 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001142
Brett Cannon22565aa2006-06-09 22:31:23 +00001143- Bug #532646: object.__call__() will continue looking for the __call__
1144 attribute on objects until one without one is found. This leads to recursion
1145 when you take a class and set its __call__ attribute to an instance of the
1146 class. Originally fixed for classic classes, but this fix is for new-style.
1147 Removes the infinite_rec_3 crasher.
1148
Georg Brandl24250812006-06-09 18:45:48 +00001149- The string and unicode methods startswith() and endswith() now accept
1150 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1151
Brett Cannonde3b0522006-06-08 17:00:45 +00001152- Buffer objects, at the C level, never used the char buffer
1153 implementation even when the char buffer for the wrapped object was
1154 explicitly requested (originally returned the read or write buffer).
1155 Now a TypeError is raised if the char buffer is not present but is
1156 requested.
1157
Georg Brandlddbaa662006-06-04 21:56:52 +00001158- Patch #1346214: Statements like "if 0: suite" are now again optimized
1159 away like they were in Python 2.4.
1160
Georg Brandlb7c8f542006-05-27 12:30:25 +00001161- Builtin exceptions are now full-blown new-style classes instead of
1162 instances pretending to be classes, which speeds up exception handling
1163 by about 80% in comparison to 2.5a2.
1164
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001165- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1166 Unicode 4.1.
1167
Georg Brandlf4ef1162006-05-26 18:03:31 +00001168- Patch #921466: sys.path_importer_cache is now used to cache valid and
1169 invalid file paths for the built-in import machinery which leads to
1170 fewer open calls on startup.
1171
Tim Peters696cf432006-05-24 21:10:40 +00001172- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1173 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1174 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1175 the number of input digits (it was and remains linear-time for bases
1176 2, 4, 8, 16 and 32).
1177
Tim Petersb713ec22006-05-23 18:45:30 +00001178- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1179 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1180 an integer close to ``sys.maxint``. This was repaired by patch
1181 #1335972, which also gives a nice speedup.
1182
Richard Jonescebbefc2006-05-23 18:28:17 +00001183- Patch #1337051: reduced size of frame objects.
1184
1185- PyErr_NewException now accepts a tuple of base classes as its
1186 "base" parameter.
1187
Richard Jones7c88dcc2006-05-23 10:37:38 +00001188- Patch #876206: function call speedup by retaining allocated frame
1189 objects.
1190
Georg Brandl7b90e162006-05-18 07:01:27 +00001191- Bug #1462152: file() now checks more thoroughly for invalid mode
1192 strings and removes a possible "U" before passing the mode to the
1193 C library function.
1194
Neal Norwitz1004a532006-05-15 07:17:23 +00001195- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1196
Neal Norwitz373f0a72006-05-15 07:04:36 +00001197- Bug #1487966: Fix SystemError with conditional expression in assignment
1198
Martin v. Löwis879768d2006-05-11 13:28:43 +00001199- WindowsError now has two error code attributes: errno, which carries
1200 the error values from errno.h, and winerror, which carries the error
1201 values from winerror.h. Previous versions put the winerror.h values
1202 (from GetLastError()) into the errno attribute.
1203
Martin v. Löwis77736712006-05-04 05:51:03 +00001204- Patch #1475845: Raise IndentationError for unexpected indent.
1205
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001206- Patch #1479181: split open() and file() from being aliases for each other.
1207
Tim Peters44bd9862006-06-01 13:49:23 +00001208- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1209 methods were always silently ignored by dictionaries when comparing keys.
1210 They are now passed through (except when using the C API function
1211 ``PyDict_GetItem()``, whose semantics did not change).
1212
1213- Bug #1456209: In some obscure cases it was possible for a class with a
1214 custom ``__eq__()`` method to confuse dict internals when class instances
1215 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1216 No, you don't have any code that did this ;-)

1219-----------------
1220
Trent Mick960a3f82006-06-28 20:30:41 +00001221- Bug #1295808: expat symbols should be namespaced in pyexpat
1222
1223- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1224
Brett Cannon6ee7d012006-06-08 16:23:04 +00001225- Change binascii.hexlify to accept a read-only buffer instead of only a char
1226 buffer and actually follow its documentation.
1227
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001228- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1229
Nick Coghlanc649ec52006-05-29 12:43:05 +00001230- Patch #1478788 (modified version): The functional extension module has
1231 been renamed to _functools and a functools Python wrapper module added.
1232 This provides a home for additional function related utilities that are
1233 not specifically about functional programming. See PEP 309.
1234
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001235- Patch #1493701: performance enhancements for struct module.
1236
Georg Brandl378d5922006-05-17 14:26:50 +00001237- Patch #1490224: time.altzone is now set correctly on Cygwin.
1238
Georg Brandl8d3342b2006-05-16 07:38:27 +00001239- Patch #1435422: zlib's compress and decompress objects now have a
1240 copy() method.
1241
Andrew MacIntyre92913322006-06-13 15:04:24 +00001242- Patch #1454481: thread stack size is now tunable at runtime for thread
1243 enabled builds on Windows and systems with Posix threads support.
1244
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001245- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1246 (up to the system limit of 32K characters).
1247
1248- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1249 As a result, these functions now raise WindowsError instead of OSError.
1250
Tim Peters7a822da2006-05-25 21:50:17 +00001251- ``time.clock()`` on Win64 should use the high-performance Windows
1252 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1253 Windows platforms).
1254
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001255- Calling Tk_Init twice is refused if the first call failed as that
1256 may deadlock.
1257
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001258- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1259 accept it without potentially using an uninitialized pointer.
1260
1261- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1262 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1263 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001264
Gregory P. Smith372b5832006-06-05 18:48:21 +00001265- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001266 [pybsddb project SF patch number 1466734]
1267
Gregory P. Smith372b5832006-06-05 18:48:21 +00001268- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1269 parameter is supplied. [SF pybsddb bug #1477863]
1270
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001271- bsddb: the __len__ method of a DB object has been fixed to return correct
1272 results. It could previously incorrectly return 0 in some cases.
1273 Fixes SF bug 1493322 (pybsddb bug 1184012).
1274
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001275- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1276 aborts the db transaction safely when a modifier callback fails.
1277 Fixes SF python patch/bug #1408584.
1278
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001279- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001280 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001281 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1282 database calls that would previously deadlock. [SF python bug #775414]
1283
Vinay Sajip28e57612006-07-01 10:45:20 +00001284- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001285
Walter Dörwald4994d952006-06-19 08:07:50 +00001286- Patch #1506645: add Python wrappers for the curses functions
1287 is_term_resized, resize_term and resizeterm.

1293 functions.
1294
Martin v. Löwis3798da02006-06-17 18:44:27 +00001295- Patch #812986: Update turtle output even if not tracing.

Vinay Sajip28e57612006-07-01 10:45:20 +00001297- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001298 Tkinter.BaseWidget.
1299
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001300- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1301
Martin v. Löwis337487e2006-06-17 09:15:14 +00001302- Patch #763580: Add name and value arguments to Tkinter variable
1303 classes.
1304
Georg Brandl83cc0d02006-06-14 08:50:03 +00001305- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1306 mime.types file for determining MIME types.
1307
Georg Brandl2605ca82006-06-14 06:08:31 +00001308- Bug #1339007: Shelf objects now don't raise an exception in their
1309 __del__ method when initialization failed.
1310
Martin v. Löwisd8251432006-06-14 05:21:04 +00001311- Patch #1455898: The MBCS codec now supports the incremental mode for
1312 double-byte encodings.
1313
Tim Peters43898b42006-06-14 04:09:25 +00001314- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1315 guarantee that adjacent triples in the return list always describe
1316 non-adjacent blocks. Previously, a pair of matching blocks could end
1317 up being described by multiple adjacent triples that formed a partition
1318 of the matching pair.
1319
Greg Ward0e0c9f42006-06-11 16:24:11 +00001320- Bug #1498146: fix optparse to handle Unicode strings in option help,
1321 description, and epilog.
1322
Greg Wardd1c797e2006-06-11 14:42:41 +00001323- Bug #1366250: minor optparse documentation error.
1324
Greg Ward7f547402006-06-11 00:40:49 +00001325- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1326 clarify docs.
1327
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001328- The wsgiref package has been added to the standard library.
1329
Nick Coghlan676725d2006-06-08 13:54:49 +00001330- The functions update_wrapper() and wraps() have been added to the functools
1331 module. These make it easier to copy relevant metadata from the original
1332 function when writing wrapper functions.
1333
Tim Petersd6a9eef2006-06-05 01:48:21 +00001334- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1335 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001336
Martin v. Löwis3f767792006-06-04 19:36:28 +00001337- Patch #1359618: Speed up charmap encoder by using a trie structure
1338 for lookup.
1339
Tim Petersd609b1a2006-06-02 23:22:51 +00001340- The functions in the ``pprint`` module now sort dictionaries by key
1341 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1342 if and only if its display required more than one line, although that
1343 wasn't documented. The new behavior increases predictability; e.g.,
1344 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1345
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001346- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1347 (thanks for J. J. Lee).
1348
Georg Brandl2b330372006-05-28 20:23:12 +00001349- Patch #1496206: improve urllib2 handling of passwords with respect to
1350 default HTTP and HTTPS ports.
1351
George Yoshidaf3c65de2006-05-28 16:39:09 +00001352- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1353
Bob Ippolito7298f272006-05-23 18:43:47 +00001354- Patch #1281707: speed up gzip.readline.
1355
Georg Brandlb89316f2006-05-17 15:51:16 +00001356- Patch #1180296: Two new functions were added to the locale module:
1357 format_string() to get the effect of "format % items" but locale-aware,
1358 and currency() to format a monetary number with currency sign.
1359
Georg Brandle3a25832006-05-17 14:56:04 +00001360- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1361 and several features added, such as speed and geometry control.
1362
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001363- Patch #1488881: add support for external file objects in bz2 compressed
1364 tarfiles.
1365
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001366- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1367 stdout arguments, making it possible to redirect input and output
1368 for remote debugging.
1369
1370- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1371 a couple of issues, notably handling of long file names using the
1372 GNU LONGNAME extension.
1373
1374- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1375 new flag when ``name`` is already the name of an option flag.
1376
1377- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1378 package.
1379
1380- Patch #1472854: make the rlcompleter.Completer class usable on non-
1381 UNIX platforms.
1382
1383- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1384
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001385- Bug #1472827: correctly escape newlines and tabs in attribute values in
1386 the saxutils.XMLGenerator class.

1421Core and builtins
1422-----------------
1423
Thomas Heller1b046642006-04-18 18:51:06 +00001424- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1425 by converting these apis from macros into exported functions again:
1426
1427 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1428 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1429 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1430 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1431 PyRun_String Py_CompileString
1432
Martin v. Löwis45294a92006-04-18 06:24:08 +00001433- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1434
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001435- All uses of PyStructSequence_InitType have been changed to initialize
1436 the type objects only once, even if the interpreter is initialized
1437 multiple times.
1438
Neal Norwitz61546162006-04-14 05:20:28 +00001439- Bug #1454485, array.array('u') could crash the interpreter. This was
1440 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1441 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1442
1443- Py_UNICODE is unsigned. It was always documented as unsigned, but
1444 due to a bug had a signed value in previous versions.
1445
Tim Peters3a5e8b12006-04-11 01:44:07 +00001446- Patch #837242: ``id()`` of any Python object always gives a positive
1447 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1448 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001449 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001450 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001451
Tim Peters3a5e8b12006-04-11 01:44:07 +00001452 def __hash__(self):
1453 return id(self) # WRONG
1454
1455 because a hash result must be a (short) Python int but it was always
1456 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001457 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001458 was always usable as a hash value before this patch. That's no longer
1459 necessarily so.
1460
1461- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001462 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001463 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001464 #1454844)
1465
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001466- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1467 involving generators that have paused outside of any ``try`` or ``with``
1468 blocks. (In 2.5a1, a paused generator that was part of a reference
1469 cycle could not be garbage collected, regardless of whether it was
1470 paused in a ``try`` or ``with`` block.)

1473-----------------
1474
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001475- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1476 is a macro.
1477
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001478- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1479 fails with an error condition.
1480
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001481- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1482
1483- Bug #1117761: bsddb.*open() no longer raises an exception when using
1484 the cachesize parameter.
1485
1486- Bug #1149413: bsddb.*open() no longer raises an exception when using
1487 a temporary db (file=None) with the 'n' flag to truncate on open.
1488
1489- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1490 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001491
Armin Rigoa9017c32006-04-19 11:50:27 +00001492- Patch #1062014: AF_UNIX sockets under Linux have a special

1497
Peter Astrand7d1d4362006-07-14 14:04:45 +00001498- Bug #1223937: subprocess.CalledProcessError reports the exit status
1499 of the process using the returncode attribute, instead of
1500 abusing errno.
1501
Tim Peters711bf302006-04-25 03:31:36 +00001502- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1503 a doctest to be skipped (the code is not run, and the expected output
1504 or exception is ignored).
1505
Nick Coghlanda2268f2006-04-24 04:37:15 +00001506- Fixed contextlib.nested to cope with exceptions being raised and
1507 caught inside exit handlers.
1508
Greg Wardab05edc2006-04-23 03:47:58 +00001509- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1510 hex, octal, or binary; add ``append_const`` action; keep going if
1511 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1512 added ``epilog`` for better help generation).
1513
Tim Peters21fbd572006-04-21 21:18:10 +00001514- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1515 called from a thread spawned as a side effect of importing a module.
1516
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001517- The pydoc module now supports documenting packages contained in
1518 .zip or .egg files.
1519
1520- The pkgutil module now has several new utility functions, such
1521 as ``walk_packages()`` to support working with packages that are either
1522 in the filesystem or zip files.
1523
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001524- The mailbox module can now modify and delete messages from
1525 mailboxes, in addition to simply reading them. Thanks to Gregory
1526 K. Johnson for writing the code, and to the 2005 Google Summer of
1527 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001528
Tim Petersc7605f22006-04-17 21:12:33 +00001529- The ``__del__`` method of class ``local`` in module ``_threading_local``
1530 returned before accomplishing any of its intended cleanup.

1537
Anthony Baxtere29002c2006-04-12 12:07:31 +00001538- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1539 Windows. Bug #1469163.
1540
Phillip J. Eby47032112006-04-11 01:07:43 +00001541- The warnings, linecache, inspect, traceback, site, and doctest modules
1542 were updated to work correctly with modules imported from zipfiles or
1543 via other PEP 302 __loader__ objects.
1544
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001545- Patch #1467770: Reduce usage of subprocess._active to processes which

1551
Skip Montanaro262fb922006-04-21 02:31:07 +00001552- The pstats.Stats class accepts an optional stream keyword argument to
1553 direct output to an alternate file-like object.
1554
Anthony Baxter51bcb682006-04-05 14:51:42 +00001555Build
1556-----
1557
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001558- The Makefile now has a reindent target, which runs reindent.py on
1559 the library.
1560
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001561- Patch #1470875: Building Python with MS Free Compiler
1562
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001563- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001564
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001565- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1566 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001567 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001568 CXX from --with-cxx-main, see description in README.
1569
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001570- Patch #1429775: Link extension modules with the shared libpython.
1571
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001572- Fixed a libffi build problem on MIPS systems.
1573
Tim Peters8931ff12006-05-13 23:28:20 +00001574- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1575 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1576 and "%zu" for unsigned integers of type ``size_t``.
1577
Anthony Baxter51bcb682006-04-05 14:51:42 +00001578Tests
1579-----
1580
Nick Coghlanda2268f2006-04-24 04:37:15 +00001581- test_contextlib now checks contextlib.nested can cope with exceptions
1582 being raised and caught inside exit handlers.
1583
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001584- test_cmd_line now checks operation of the -m and -c command switches
1585
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001586- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1587 it separately and by hand. It also wasn't cleaning up its changes to
1588 the current Decimal context.
1589
Thomas Woutersabd08882006-04-26 15:53:30 +00001590- regrtest.py now has a -M option to run tests that test the new limits of
1591 containers, on 64-bit architectures. Running these tests is only sensible
1592 on 64-bit machines with more than two gigabytes of memory. The argument
1593 passed is the maximum amount of memory for the tests to use.
1594
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001595Tools

Anthony Baxter51bcb682006-04-05 14:51:42 +00001601Documentation
1602-------------
1603
Tim Petersb06d28c2006-05-12 01:57:59 +00001604- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1605
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001606- PEP 343: Added Context Types section to the library reference
1607 and attempted to bring other PEP 343 related documentation into
1608 line with the implementation and/or python-dev discussions.
1609
Tim Peters8dc73d22006-04-24 02:03:16 +00001610- Bug #1337990: clarified that ``doctest`` does not support examples
1611 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001614What's New in Python 2.5 alpha 1?
1615=================================
1616
Anthony Baxterebed3f62006-04-03 15:03:44 +00001617*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001618
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001619Core and builtins
1620-----------------
1621
Nick Coghlan43832302006-04-23 17:04:07 +00001622- PEP 338: -m command line switch now delegates to runpy.run_module
1623 allowing it to support modules in packages and zipfiles
1624
Martin v. Löwisc661b882006-04-20 04:54:23 +00001625- On Windows, .DLL is not an accepted file name extension for
1626 extension modules anymore; extensions are only found if they
1627 end in .PYD.
1628
Martin v. Löwisea62d252006-04-03 10:56:49 +00001629- Bug #1421664: sys.stderr.encoding is now set to the same value as
1630 sys.stdout.encoding.
1631
Neal Norwitz92e212f2006-04-03 04:48:37 +00001632- __import__ accepts keyword arguments.
1633
Georg Brandlccadf842006-03-31 18:54:53 +00001634- Patch #1460496: round() now accepts keyword arguments.
1635
Anthony Baxter262c00a2006-03-30 10:53:17 +00001636- Fixed bug #1459029 - unicode reprs were double-escaped.
1637
Hye-Shik Changd478f342006-03-23 12:32:36 +00001638- Patch #1396919: The system scope threads are reenabled on FreeBSD
1639 5.4 and later versions.
1640
Neal Norwitze98ccf62006-03-23 05:39:47 +00001641- Bug #1115379: Compiling a Unicode string with an encoding declaration
1642 now gives a SyntaxError.
1643
Georg Brandlabd1ff82006-03-18 07:59:59 +00001644- Previously, Python code had no easy way to access the contents of a
1645 cell object. Now, a ``cell_contents`` attribute has been added
1646 (closes patch #1170323).
1647
Tim Peterscf79aac2006-03-16 01:14:46 +00001648- Patch #1123430: Python's small-object allocator now returns an arena to
1649 the system ``free()`` when all memory within an arena becomes unused
1650 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1651 freed. Some applications will see a drop in virtual memory size now,
1652 especially long-running applications that, from time to time, temporarily
1653 use a large number of small objects. Note that when Python returns an
1654 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001655 platform C library will in turn return that memory to the operating system.
1656 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001657 appears to be effective at least on Microsoft C and gcc-based systems.
1658 Thanks to Evan Jones for hard work and patience.
1659
Georg Brandl533ff6f2006-03-08 18:09:27 +00001660- Patch #1434038: property() now uses the getter's docstring if there is
1661 no "doc" argument given. This makes it possible to legitimately use
1662 property() as a decorator to produce a read-only property.
1663
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001664- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1665 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1666 of requiring an int or long in slicing and a few other contexts, enabling
1667 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1668
Neal Norwitz995acdf2006-03-07 05:01:00 +00001669- Fixed various bugs reported by Coverity's Prevent tool.
1670
Brett Cannonbf364092006-03-01 04:25:17 +00001671- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1672 new exception base class, BaseException, which has a new message attribute.
1673 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1674 Raising a string exception now raises a DeprecationWarning.
1675
Thomas Woutersfb609f42006-02-28 16:37:25 +00001676- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1677 explicitly relative, using 'from .module import name' to mean 'from the same
1678 package as this module is in. Imports without dots still default to the
1679 old relative-then-absolute, unless 'from __future__ import
1680 absolute_import' is used.
1681
Brett Cannona7446e32006-02-27 23:39:10 +00001682- Properly check if 'warnings' raises an exception (usually when a filter set
1683 to "error" is triggered) when raising a warning for raising string
1684 exceptions.
1685
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001686- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001687 The name was removed from Include/code.h.
1688
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001689- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001690
Guido van Rossum1968ad32006-02-25 22:38:04 +00001691- Patch 1433928:
1692 - The copy module now "copies" function objects (as atomic objects).
1693 - dict.__getitem__ now looks for a __missing__ hook before raising
1694 KeyError.
1695
Tim Peters84ef21c2006-02-28 20:39:06 +00001696- PEP 343: with statement implemented. Needs ``from __future__ import
1697 with_statement``. Use of 'with' as a variable will generate a warning.
1698 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001699 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001700 The following objects have __context__ methods:
1701 - The built-in file type.
1702 - The thread.LockType type.
1703 - The following types defined by the threading module:
1704 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1705 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001706
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001707- Fix the encodings package codec search function to only search
1708 inside its own package. Fixes problem reported in patch #1433198.
1709
1710 Note: Codec packages should implement and register their own
1711 codec search function. PEP 100 has the details.
1712
Tim Peters9ea89d22006-06-04 03:26:02 +00001713- PEP 353: Using ``Py_ssize_t`` as the index type.
1714
1715- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1716 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1717 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1718 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1719 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001720
Neal Norwitzfc76d632006-01-10 06:03:13 +00001721- Patch #1400181, fix unicode string formatting to not use the locale.
1722 This is how string objects work. u'%f' could use , instead of .
1723 for the decimal point. Now both strings and unicode always use periods.
1724
Neal Norwitz671b9e32006-01-09 07:07:12 +00001725- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1726 configure would break checking curses.h.
1727
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001728- Bug #959576: The pwd module is now builtin. This allows Python to be
1729 built on UNIX platforms without $HOME set.
1730
Neal Norwitzc10978f2005-12-19 06:07:16 +00001731- Bug #1072182, fix some potential problems if characters are signed.
1732
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001733- Bug #889500, fix line number on SyntaxWarning for global declarations.
1734
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001735- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1736
Neal Norwitze7214a12005-12-18 05:03:17 +00001737- Support for converting hex strings to floats no longer works.
1738 This was not portable. float('0x3') now raises a ValueError.
1739
Barry Warsaw2a38a862005-12-18 01:27:35 +00001740- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001741 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001742 is now displayed in interactive prompt banner.
1743
Georg Brandlfa166682005-12-17 21:45:17 +00001744- Implementation of PEP 341 - Unification of try/except and try/finally.
1745 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001746 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001747
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001748- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1749 now encodes backslash correctly.
1750
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001751- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1752
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001753- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001754 and long longs.
1755
Neal Norwitz67715f02005-11-09 06:59:35 +00001756- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001757 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001758 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001759
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001760- Replaced most Unicode charmap codecs with new ones using the
1761 new Unicode translate string feature in the builtin charmap
1762 codec; the codecs were created from the mapping tables available
1763 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1764 encodings now include a mapping for the Apple logo)
1765
Tim Peterse3547fd2005-12-16 23:13:57 +00001766- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001767
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001768- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001769
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001770- A new AST parser implementation was completed. The abstract
1771 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001772 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001773
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001774- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001775 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1776
Neal Norwitz708e51a2005-10-03 04:48:15 +00001777- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1778
Neal Norwitz11bd1192005-10-03 00:54:56 +00001779- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1780 Provide a warning when a directory is passed on the command line.
1781
Neal Norwitz40d37812005-10-02 01:48:49 +00001782- Fix segfault with invalid coding.
1783
1784- SF bug #772896: unknown encoding results in MemoryError.
1785
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001786- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001787 supported a __len__() method which evaluated to False when the iterator
1788 was empty.
1789
Guido van Rossum630db602005-09-20 18:49:54 +00001790- On 64-bit platforms, when __len__() returns a value that cannot be
1791 represented as a C int, raise OverflowError.
1792
Skip Montanarof8948ca2005-09-19 03:54:46 +00001793- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001794 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001795
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001796- SF bug #893549: parsing keyword arguments was broken with a few format
1797 codes.
1798
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001799- Changes donated by Elemental Security to make it work on AIX 5.3
1800 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1801 bug #105470: test_pwd fails on 64bit system (Opteron).
1802
Guido van Rossum539c6622005-09-14 17:49:54 +00001803- Changes donated by Elemental Security to make it work on HP-UX 11 on
1804 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1805
Georg Brandl4550b8d2005-08-26 06:43:52 +00001806- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001807 (fixes bug #1119418).
1808
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001809- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1810
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001811- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1812 exceptions that cause a function to exit.
1813
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001814- The implementation of set() and frozenset() was revised to use its
1815 own internal data structure. Memory consumption is reduced by 1/3
1816 and there are modest speed-ups as well. The API is unchanged.
1817
Tim Petersde7990b2005-07-17 23:45:23 +00001818- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1819
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001820- SF bug #1229429: PyObject_CallMethod failed to decrement some
1821 reference counts in some error exit cases.
1822
Tim Petersecc6e6a2005-07-10 22:30:55 +00001823- SF bug #1185883: Python's small-object memory allocator took over
1824 a block managed by the platform C library whenever a realloc specified
1825 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001826 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001827 portable way to copy data from the C-managed block into Python's
1828 small-object space without risking a memory fault. Python's small-object
1829 realloc now leaves such blocks under the control of the platform C
1830 realloc.
1831
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001832- SF bug #1232517: An overflow error was not detected properly when
1833 attempting to convert a large float to an int in os.utime().
1834
Raymond Hettinger3296e692005-06-29 23:29:56 +00001835- SF bug #1224347: hex longs now print with lowercase letters just
1836 like their int counterparts.
1837
Michael W. Hudson188d4362005-06-20 16:52:57 +00001838- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1839 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1840 interpreter states; back out that fix and do a better job (see
1841 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1842 for a longer write-up of the problem).
1843
Michael W. Hudsondf888462005-06-03 14:41:55 +00001844- SF patch #1180995: marshal now uses a binary format by default when
1845 serializing floats.
1846
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001847- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1848 the routines that promise to produce IEEE 754 binary representations
1849 of floats now simply copy bytes around.
1850
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001851- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1852 278.
1853
Brett Cannonc3647ac2005-04-26 03:45:26 +00001854- patch #1109424: int, long, float, complex, and unicode now check for the
1855 proper magic slot for type conversions when subclassed. Previously the
1856 magic slot was ignored during conversion. Semantics now match the way
1857 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00001858 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00001859 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00001860 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00001861
Barry Warsawc8d907c2005-04-19 23:43:40 +00001862- Descriptors defined in C with a PyGetSetDef structure, where the setter is
1863 NULL, now raise an AttributeError when attempting to set or delete the
1864 attribute. Previously a TypeError was raised, but this was inconsistent
1865 with the equivalent pure-Python implementation.
1866
Michael W. Hudson774479c2005-04-18 08:46:17 +00001867- It is now safe to call PyGILState_Release() before
1868 PyEval_InitThreads() (note that if there is reason to believe there
1869 are multiple threads around you still must call PyEval_InitThreads()
1870 before using the Python API; this fix is for extension modules that
1871 have no way of knowing if Python is multi-threaded yet).
1872
Michael W. Hudsone3afc592005-04-07 10:11:19 +00001873- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
1874 disabled caused a crash.
1875
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00001876- Bug #1165306: instancemethod_new allowed the creation of a method
1877 with im_class == im_self == NULL, which caused a crash when called.
1878
Tim Petersecc6e6a2005-07-10 22:30:55 +00001879- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001880 fixes the crash seen in bug #1165761
1881
Raymond Hettinger96229b12005-03-11 06:49:40 +00001882- Added two new builtins, any() and all().
1883
Brett Cannon409d8f22005-03-05 06:47:57 +00001884- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00001885 (e.g., ``class C(): pass`` is no longer a syntax error).
1886 Patch #1176012 added support to the 'parser' module and 'compiler' package
1887 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00001888
Martin v. Löwis96d743e2005-03-03 23:00:26 +00001889- Patch #1115086: Support PY_LONGLONG in structmember.
1890
Raymond Hettingerb67cc802005-03-03 16:45:19 +00001891- Bug #1155938: new style classes did not check that __init__() was
1892 returning None.
1893
Tim Petersecc6e6a2005-07-10 22:30:55 +00001894- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00001895 ('\') with a specific error message.
1896
Martin v. Löwisff232d72005-03-03 09:24:38 +00001897- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
1898
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00001899- Bug #1124295: the __name__ attribute of file objects was
1900 inadvertently made inaccessible in restricted mode.
1901
Tim Petersecc6e6a2005-07-10 22:30:55 +00001902- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00001903 an ferror() call.
1904
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00001905- min() and max() now support key= arguments with the same meaning as in
1906 list.sort().
1907
Raymond Hettingerc34f8672005-01-02 06:17:33 +00001908- The peephole optimizer now performs simple constant folding in expressions:
1909 (2+3) --> (5).
1910
Raymond Hettingera422c342005-01-11 03:03:27 +00001911- set and frozenset objects can now be marshalled. SF #1098985.
1912
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00001913- Bug #1077106: Poor argument checking could cause memory corruption
1914 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001915
Jeremy Hyltonab630502005-02-04 18:44:06 +00001916- The parser did not complain about future statements in illegal
1917 positions. It once again reports a syntax error if a future
1918 statement occurs after anything other than a doc string.
1919
Neil Schemenauercf52c072005-08-12 17:34:58 +00001920- Change the %s format specifier for str objects so that it returns a
1921 unicode instance if the argument is not an instance of basestring and
1922 calling __str__ on the argument returns a unicode instance.
1923
Tim Petersf4e69282006-02-27 17:15:31 +00001924- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
1925 current thread state when the auto-GIL-state machinery knows about
1926 it (since the thread state is being deleted, continuing to remember it
1927 can't help, but can hurt if another thread happens to get created with
1928 the same thread id).
1929
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001930Extension Modules
1931-----------------
1932

Neal Norwitz10be10c2006-03-16 06:50:13 +00001946 util, whatsound, whrandom, zmod
1947
1948- The following modules were removed: regsub, reconvert, regex, regex_syntax.
1949
1950- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00001951 is deprecated. The undocumented re.engine variable no longer exists.
1952
Hye-Shik Changabb903f2006-03-13 10:20:08 +00001953- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
1954 SS2 (single-shift 2) escape sequences correctly.
1955
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00001956- The unicodedata module was updated to the 4.1 version of the Unicode
1957 database. The 3.2 version is still available as unicodedata.db_3_2_0
1958 for applications that require this specific version (such as IDNA).
1959
Neal Norwitzb62c4332006-03-04 18:35:47 +00001960- The timing module is no longer built by default. It was deprecated
1961 in PEP 4 in Python 2.0 or earlier.
1962
Guido van Rossum1968ad32006-02-25 22:38:04 +00001963- Patch 1433928: Added a new type, defaultdict, to the collections module.
1964 This uses the new __missing__ hook behavior added to dict (see above).
1965
Georg Brandldbd83392006-02-20 09:42:33 +00001966- Bug #854823: socketmodule now builds on Sun platforms even when
1967 INET_ADDRSTRLEN is not defined.
1968
Georg Brandlf4f44152006-02-18 22:29:33 +00001969- Patch #1393157: os.startfile() now has an optional argument to specify
1970 a "command verb" to invoke on the file.
1971
Neal Norwitz082b2df2006-02-07 07:04:46 +00001972- Bug #876637, prevent stack corruption when socket descriptor

1974
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00001975- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
1976 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
1977 mmap.mmap(0, size) should not be used on Windows for anonymous memory.

1980 than the system default domain.
1981
Martin v. Löwis14694662006-02-03 12:54:16 +00001982- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
1983 are reported, the limit on path name lengths is removed, and stat reports
1984 WindowsError now (instead of OSError).
1985
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00001986- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

2061 the request code argument, which results in more C-like behaviour
2062 for large or negative values.
2063
Tim Petersecc6e6a2005-07-10 22:30:55 +00002064- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

2079
Raymond Hettinger984f9bb2005-03-09 16:38:48 +00002080- operator.itemgetter() and operator.attrgetter() now support retrieving

Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002104- the cPickle module no longer accepts the deprecated None option in the
2105 args tuple returned by __reduce__().
2106
Raymond Hettingerb2594052004-12-05 09:25:51 +00002107- itertools.islice() now accepts None for the start and step arguments.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002120- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2121 been renamed to have only a single underscore prefix. This was done to
2122 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002123
Nick Coghlan43832302006-04-23 17:04:07 +00002124- PEP 338: new module runpy defines a run_module function to support
2125 executing modules which provide access to source code or a code object
2126 via the PEP 302 import mechanisms.
2127
Anthony Baxter93f5b932006-04-03 08:05:07 +00002128- The email module's parsedate_tz function now sets the daylight savings

2136 in attribute values.
2137
Anthony Baxterc51ee692006-04-01 00:57:31 +00002138- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002139 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002140 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002141 module will not be built.
2142
Tim Petersc17976e2006-04-01 00:26:53 +00002143- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2144 aren't officially supported here, and trying to use them will probably
2145 raise an exception some day. But dicts have been allowed, and "mostly
2146 worked", so support for them won't go away without warning.
2147
Georg Brandl338ef7d2006-03-31 18:42:16 +00002148- Bug #1445068: getpass.getpass() can now be given an explicit stream
2149 argument to specify where to write the prompt.
2150
Georg Brandl22ec80b2006-03-31 18:25:44 +00002151- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2158
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002159- Queue.Queue objects now support .task_done() and .join() methods
2160 to make it easier to monitor when daemon threads have completed
2161 processing all enqueued tasks. Patch #1455676.
2162

2166
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002167- email 4.0 package now integrated. This is largely the same as the email 3.0
2168 package that was included in Python 2.3, except that PEP 8 module names are
2169 now used (e.g. mail.message instead of email.Message). The MIME classes
2170 have been moved to a subpackage (e.g. email.mime.text instead of
2171 email.MIMEText). The old names are still supported for now. Several
2172 deprecated Message methods have been removed and lots of bugs have been
2173 fixed. More details can be found in the email package documentation.
2174
Walter Dörwald40108c92006-03-27 08:15:44 +00002175- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2176 (a subclass of tuple) that provides incremental decoders and encoders
2177 (a way to use stateful codecs without the stream API). Python functions
2178 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2179 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2180 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002181
Walter Dörwald067db482006-03-15 22:17:27 +00002182- Patch #1359365: Calling next() on a closed StringIO.String object raises
2183 a ValueError instead of a StopIteration now (like file and cString.String do).
2184 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2185 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002186
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002187- A regrtest option -w was added to re-run failed tests in verbose mode.

Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002198- PEP 343: new module contextlib.py defines decorator @contextmanager
2199 and helpful context managers nested() and closing().
2200

Martin v. Löwis3e865952006-01-24 15:51:21 +00002235 specifications, raises IOErrors when proxies for unsupported protocols
2236 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00002259 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2260 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2261 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2262 Ronald L. Rivest offered this advice for Python:
2263
2264 "The consensus of researchers in this area (at least as
2265 expressed at the NIST Hash Function Workshop 10/31/05),
2266 is that SHA-256 is a good choice for the time being, but
2267 that research should continue, and other alternatives may
2268 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002269
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002270- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandlb9256022005-08-24 18:46:39 +00002316- Patch #1062060: urllib.urlretrieve() now raises a new exception, named
2317 ContentTooShortException, when the actually downloaded size does not
2318 match the Content-Length header.
2319
Martin v. Löwis0a5d4a22005-08-24 14:55:22 +00002320- Bug #1121494: distutils.dir_utils.mkpath now accepts Unicode strings.
2321
Martin v. Löwis56066d22005-08-24 07:38:12 +00002322- Bug #1178484: Return complete lines from codec stream readers
2323 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002324 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002325

2339
Georg Brandla4a8b822005-07-15 09:13:21 +00002340- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
2341 parameter, but uses the usual "kwargs=None".
2342
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002343- textwrap now processes text chunks at O(n) speed instead of O(n**2).

2345
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00002346- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
2347 to W3C name (404 -> 'Not Found'). RFE #1216944.
2348
Georg Brandl9e43acf2005-07-04 17:16:07 +00002349- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2350 as this can cause problems with apps closing all file descriptors.
2351
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002352- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002353 it can be missing in embedded interpreters

2361
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00002362- The tokenize module now detects and reports indentation errors.
2363 Bug #1224621.
2364
Raymond Hettinger68c04532005-06-10 11:05:19 +00002365- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002366 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002367 the generate_tokens() function now accepts a callable argument that
2368 terminates by raising StopIteration.
2369
Georg Brandl9166e1a2005-06-04 09:20:03 +00002370- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2371
Georg Brandl268e61c2005-06-03 14:28:50 +00002372- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2373 component of the path.
2374
Skip Montanaro174dd222005-05-14 20:54:16 +00002375- Patch #1120353: The xmlrpclib module provides better, more transparent,
2376 support for datetime.{datetime,date,time} objects. With use_datetime set
2377 to True, applications shouldn't have to fiddle with the DateTime wrapper
2378 class at all.
2379
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002380- distutils.commands.upload was added to support uploading distribution
2381 files to PyPI.
2382
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002383- distutils.commands.register now encodes the data as UTF-8 before posting
2384 them to PyPI.
2385
Raymond Hettinger267b8682005-03-27 10:47:39 +00002386- decimal operator and comparison methods now return NotImplemented
2387 instead of raising a TypeError when interacting with other types. This
2388 allows other classes to implement __radd__ style methods and have them
2389 work as expected.
2390
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002391- Bug #1163325: Decimal infinities failed to hash. Attempting to
2392 hash a NaN raised an InvalidOperation instead of a TypeError.
2393
Tim Petersecc6e6a2005-07-10 22:30:55 +00002394- Patch #918101: Add tarfile open mode r|* for auto-detection of the

2428
Guido van Rossumd0641422005-02-03 15:01:24 +00002429- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2430 disables recursive traversal through instance attributes, which can
2431 be exploited in various ways.
2432
Tim Peterse3547fd2005-12-16 23:13:57 +00002433- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002434 flags on the HTTP listening socket.
2435
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002436- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2437 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2438
Fred Drakefbdeaad2006-07-29 16:56:15 +00002439- Patches #893642, #1039083: add allow_none, encoding arguments to
2440 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002441
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002442- Bug #1110478: Revert os.environ.update to do putenv again.
2443
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002444- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2445
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002446- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2447
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002448- Enhancements to the csv module:
2449
2450 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002451 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002452 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002453 + Dialect parameter parsing has been re-implemented to improve error
2454 reporting.
2455 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2456 dictates.
2457 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002458 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002459 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002460 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2461 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002462 + reader now allows \r characters to be quoted (previously it only allowed
2463 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002464 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002465 + Dialect classes passed to the module are no longer instantiated by
2466 the module before being parsed (the former validation scheme required
2467 this, but the mechanism was unreliable).
2468 + The dialect registry now contains instances of the internal
2469 C-coded dialect type, rather than references to python objects.
2470 + the internal c-coded dialect type is now immutable.
2471 + register_dialect now accepts the same keyword dialect specifications
2472 as the reader and writer, allowing the user to register dialects
2473 without first creating a dialect class.
2474 + a configurable limit to the size of parsed fields has been added -
2475 previously, an unmatched quote character could result in the entire
2476 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002477 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002478 the parser field size limit (returning the former limit). The initial
2479 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002480 + A line_num attribute has been added to the reader object, which tracks
2481 the number of lines read from the source iterator. This is not
2482 the same as the number of records returned, as records can span
2483 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002484 + reader and writer objects were not being registered with the cyclic-GC.
2485 This has been fixed.
2486
Brett Cannone6539c42005-01-08 02:43:53 +00002487- _DummyThread objects in the threading module now delete self.__block that is
2488 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2489 lock primitives tend to be limited in number and thus should not be wasted on
2490 a _DummyThread object. Fixes bug #1089632.
2491
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002492- The imghdr module now detects Exif files.
2493
Raymond Hettinger6065d322004-12-20 23:51:53 +00002494- StringIO.truncate() now correctly adjusts the size attribute.
2495 (Bug #951915).
2496
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002497- locale.py now uses an updated locale alias table (built using
2498 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2499 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002500 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002501
Raymond Hettinger3557f422004-12-07 12:02:02 +00002502- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2503
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002504- the pickle module no longer accepts the deprecated None option in the
2505 args tuple returned by __reduce__().
2506
Brett Cannon84667c02004-12-07 03:25:18 +00002507- optparse now optionally imports gettext. This allows its use in setup.py.
2508
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002509- the pickle module no longer uses the deprecated bin parameter.
2510
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002511- the shelve module no longer uses the deprecated binary parameter.
2512
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002513- the pstats module no longer uses the deprecated ignore() method.
2514
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002515- the filecmp module no longer uses the deprecated use_statcache argument.
2516
Raymond Hettinger664347b2004-12-04 21:21:53 +00002517- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2518 extended or overridden by subclasses. Formerly, the subclassed method would
2519 be ignored by the rest of the module. (Bug #1078905).
2520
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002521- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002522 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002523
Walter Dörwald36733692004-12-22 12:50:50 +00002524- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2525 once when a size argument is given. This prevents a buffer overflow in the
2526 tokenizer with very long source lines.
2527
Barry Warsaw538561e2006-01-01 21:48:54 +00002528- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2529 immediately after creating the object, without any intervening
2530 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002531
Skip Montanaro05885812005-01-16 20:48:27 +00002532- The reconvert.quote function can now emit triple-quoted strings. The
2533 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002534
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002535- ``UserString.MutableString`` now supports negative indices in
2536 ``__setitem__`` and ``__delitem__``
2537
Greg Ward40407942005-03-05 02:53:17 +00002538- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2539 correctly.
2540
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002541- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2542 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2543 character even if the user has passed a size parameter to get a proper
2544 line ending. Remove the special handling of a "\r\n" that has been split
2545 between two lines.
2546
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002547- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2548 about illegal code points. The codec now supports PEP 293 style error
2549 handlers.
2550
Walter Dörwald78a78b02005-09-01 12:04:29 +00002551- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002552 from the input stream, so that the output is a byte string in the correct
2553 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002554
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002555- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2556 considering it exactly like a '*'.
2557
Walter Dörwald007f8df2005-10-09 19:42:27 +00002558- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2559 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002560
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002561- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2562
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002563- Patch #1413711: Certain patterns of differences were making difflib
2564 touch the recursion limit.
2565
Walter Dörwald58917a62006-03-31 15:26:22 +00002566- Bug #947906: An object oriented interface has been added to the calendar
2567 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002568 called as a script (e.g. via ``python -mcalendar``). Localized month and
2569 weekday names can be ouput (even if an exotic encoding is used) using
2570 special classes that use unicode.

2579
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002580- Build support for Win64-AMD64 was added.
2581
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002582- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2583
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002584- Patch #881820: look for openpty and forkpty also in libbsd.
2585
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002586- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2587 The zlib module is now builtin on Windows.
2588
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002589- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2590
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002591- Bug #1189330: configure did not correctly determine the necessary
2592 value of LINKCC if python was built with GCC 4.0.
2593
Trent Mick8321b422005-07-26 02:29:21 +00002594- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2595 vulnerability in zlib 1.2.1 and 1.2.2.
2596
Brett Cannon08cd5982005-04-24 22:26:38 +00002597- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2598 flags that change binary compatibility. Changes were also made to
2599 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002600 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002601
Bob Ippolitoed233462005-03-29 13:47:59 +00002602- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2603 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2604 no longer exists). This configure patch makes things right.
2605
Martin v. Löwise2713be2005-03-08 15:03:08 +00002606- Bug #1158607: Build with --disable-unicode again.
2607
Brett Cannon46d96232005-02-16 00:07:19 +00002608- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2609 defined. Discovered as a result of not being able to build on OS X.
2610
Brett Cannon516592f2004-12-07 00:42:59 +00002611- setup.py now uses the directories specified in LDFLAGS using the -L option
2612 and in CPPFLAGS using the -I option for adding library and include
2613 directories, respectively, for compiling extension modules against. This has
2614 led to the core being compiled using the values in CPPFLAGS. It also removes
2615 the need for the special-casing of both DarwinPorts and Fink for darwin since
2616 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2617 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2618 Fink, ``-I/opt/local/include`` for DarwinPorts).
2619
Brett Cannon43802422005-02-10 20:48:03 +00002620- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2621 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2622 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2623 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002625C API
2626-----
2627
Tim Petersc9d78aa2006-03-26 23:27:58 +00002628- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2629 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2630 is obtained via the ``PyObject_`` family, it must be released via the
2631 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2632 always been officially true, but when Python's small-object allocator was
2633 introduced, an attempt was made to cater to a few extension modules
2634 discovered at the time that obtained memory via ``PyObject_New`` but
2635 released it via ``PyMem_DEL``. It's years later, and if such code still
2636 exists it will fail now (probably with segfaults, but calling wrong
2637 low-level memory management functions can yield many symptoms).
2638
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002639- Added a C API for set and frozenset objects.
2640
Raymond Hettinger66517482004-12-03 11:45:13 +00002641- Removed PyRange_New().
2642
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002643- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2644 mapping argument now. This string is used as a mapping table. Byte values
2645 greater than the length of the string and 0xFFFE are treated as undefined
2646 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00002652- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002653
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002654- Patch #1276356: New resource "urlfetch" is implemented. This enables
2655 even impatient people to run tests that require remote files.
