604-----------------
605
Neal Norwitz0bcafac2006-09-11 08:51:17 +0000606- Make _PyGILState_NoteThreadState() static, it was not used anywhere
607 outside of pystate.c and should not be necessary.
608
Brett Cannon19d76c52006-09-09 07:18:44 +0000609- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
610 allows calling unicode() on exceptions classes directly to succeed.
611
Georg Brandlecab6232006-09-06 06:47:02 +0000612- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
613 Also make sure that every exception class has __module__ set to
614 'exceptions'.
615
Georg Brandl37a9e572006-09-06 06:09:34 +0000616- Bug #1550983: emit better error messages for erroneous relative
617 imports (if not in package and if beyond toplevel package).
618
Tim Peterscbdd3502006-09-05 01:47:53 +0000619- Overflow checking code in integer division ran afoul of new gcc
620 optimizations. Changed to be more standard-conforming.
621
Neal Norwitz19c35bb2006-08-21 22:13:11 +0000622- Patch #1541585: fix buffer overrun when performing repr() on
623 a unicode string in a build with wide unicode (UCS-4) support.
624
Neal Norwitzd3da7d32006-09-05 01:54:06 +0000625- Patch #1546288: fix seg fault in dict_equal due to ref counting bug.
626
Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000627- The return tuple from str.rpartition(sep) is (tail, sep, head) where
628 head is the original string if sep was not found.
629
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000630- Bug #1520864: unpacking singleton tuples in list comprehensions and
631 generator expressions (x for x, in ... ) works again. Fixing this problem
632 required changing the .pyc magic number. This means that .pyc files
633 generated before 2.5c2 will be regenerated.

Guido van Rossumc69ac252006-08-10 18:09:25 +0000740What's New in Python 2.5 release candidate 1?
741=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000742
Anthony Baxterb4096662006-08-16 03:42:26 +0000743*Release date: 17-AUG-2006*
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000744
745Core and builtins
746-----------------
747
Neal Norwitz24b6f202006-09-05 04:43:56 +0000748- Fix infinite recursion when subclassing long and overriding __hash__.
749
750- Fix concatenation (+=) of long strings.
751
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000752- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000753 compared equal or unequal to a string and a UnicodeDecodeError
754 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000755
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000756 Instead, the equal (==) and unequal (!=) comparison operators will
757 now issue a UnicodeWarning and interpret the two objects as
758 unequal. The UnicodeWarning can be filtered as desired using
759 the warning framework, e.g. silenced completely, turned into an
760 exception, logged, etc.
761
762 Note that compare operators other than equal and unequal will still
763 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000764
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000765- Fix segfault when doing string formatting on subclasses of long.
766
767- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
768 with new-style classes.
769
770- Fix bug related to __len__ functions returning negative values with
771 classic classes.
772
773- Patch #1538606, Fix __index__() clipping. There were some problems
774 discovered with the API and how integers that didn't fit into Py_ssize_t
775 were handled. This patch attempts to provide enough alternatives
776 to effectively use __index__.
777
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000778- Bug #1536021: __hash__ may now return long int; the final hash
779 value is obtained by invoking hash on the long int.
780
Thomas Hellerab1049c2006-08-08 17:37:00 +0000781- Bug #1536786: buffer comparison could emit a RuntimeWarning.
782
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000783- Bug #1535165: fixed a segfault in input() and raw_input() when
784 sys.stdin is closed.
785
Thomas Heller74d36f02006-08-04 18:17:40 +0000786- On Windows, the PyErr_Warn function is now exported from
787 the Python dll again.
788
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000789- Bug #1191458: tracing over for loops now produces a line event
790 on each iteration. Fixing this problem required changing the .pyc
791 magic number. This means that .pyc files generated before 2.5c1
792 will be regenerated.
793
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000794- Bug #1333982: string/number constants were inappropriately stored
795 in the byte code and co_consts even if they were not used, ie
796 immediately popped off the stack.
797
Georg Brandle9462c72006-08-04 18:03:37 +0000798- Fixed a reference-counting problem in property().
799

801Library
802-------
803
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000804- Fix a bug in the ``compiler`` package that caused invalid code to be
805 generated for generator expressions.
806
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000807- The distutils version has been changed to 2.5.0. The change to
808 keep it programmatically in sync with the Python version running
809 the code (introduced in 2.5b3) has been reverted. It will continue
810 to be maintained manually as static string literal.
811
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000812- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000813 and this cannot be converted to the required C type, an exception is
814 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000815 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000816
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000817- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000818 an exception.
819
Tim Peterscbdd3502006-09-05 01:47:53 +0000820- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000821 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000822 workarounds for clocks with low resolution, to stop the code yielding
823 duplicate UUIDs.
824
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000825- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
826 before raising SystemExit, allowing IDLE to honor quit() and exit().
827
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000828- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
829
Georg Brandl7a1af772006-08-14 21:55:28 +0000830- Patch #1536071: trace.py should now find the full module name of a
831 file correctly even on Windows.
832
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000833- logging's atexit hook now runs even if the rest of the module has
834 already been cleaned up.
835
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000836- Bug #1112549, fix DoS attack on cgi.FieldStorage.

Neal Norwitzff4b63b2006-08-04 04:50:21 +0000838- Bug #1531405, format_exception no longer raises an exception if
839 str(exception) raised an exception.
840
Neil Schemenauer06ded092006-08-04 16:20:30 +0000841- Fix a bug in the ``compiler`` package that caused invalid code to be
842 generated for nested functions.

853 raises the correct exceptions.
854
Thomas Heller1ce433e2006-08-14 16:20:04 +0000855- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
856 '-no-stack-protector' compiler flag for OpenBSD has been removed.
857
Thomas Heller86720042006-08-14 11:17:48 +0000858- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
859 uses the _as_parameter_ attribute when objects are passed to foreign
860 function calls. The ctypes version number was changed to 1.0.1.
861
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000862- Bug #1530559, struct.pack raises TypeError where it used to convert.
863 Passing float arguments to struct.pack when integers are expected
864 now triggers a DeprecationWarning.
865
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000866

Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000901- New API for Unicode rich comparisons: PyUnicode_RichCompare()
902
Tim Peters4643c2f2006-08-10 22:45:34 +0000903- Bug #1069160. Internal correctness changes were made to
904 ``PyThreadState_SetAsyncExc()``. A test case was added, and
905 the documentation was changed to state that the return value
906 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +0000909What's New in Python 2.5 beta 3?
910================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000911
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000912*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000913
914Core and builtins
915-----------------
916
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000917- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000918 returned a long (see PEP 353).
919
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000920- Bug #1515471: string.replace() accepts character buffers again.
921
Neal Norwitz07aadb12006-07-30 06:55:48 +0000922- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
923 This provides the proper warning for struct.pack().
924 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
925
Neal Norwitz0d62a062006-07-30 06:53:31 +0000926- Patch #1531113: Fix augmented assignment with yield expressions.
927 Also fix a SystemError when trying to assign to yield expressions.
928
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000929- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
930 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
931 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
932 excessive filesystem operations during imports.
933
Tim Petersbc24eee2006-07-27 01:14:53 +0000934- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
935 operations on signed longs that are formally undefined by C.
936 Unfortunately, at least one compiler now cares about that, so complicated
937 the code to make that compiler happy again.
938
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000939- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
940
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000941- Patch #1232023: Stop including current directory in search
942 path on Windows.
943
Neal Norwitze1fdb322006-07-21 05:32:28 +0000944- Fix some potential crashes found with failmalloc.
945
Neal Norwitze7563102006-07-17 01:00:16 +0000946- Fix warnings reported by Klocwork's static analysis tool.
947
Neal Norwitz84be93b2006-07-16 01:50:38 +0000948- Bug #1512814, Fix incorrect lineno's when code within a function
949 had more than 255 blank lines.
950
Georg Brandl9dceedb2006-07-12 15:31:17 +0000951- Patch #1521179: Python now accepts the standard options ``--help`` and
952 ``--version`` as well as ``/?`` on Windows.
953
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000954- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000955 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000956 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000957
Tim Peters112aad32006-07-19 00:03:19 +0000958- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000959 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000960 new ``sys._current_frames()`` returns a dictionary with one entry,
961 mapping the faux "thread id" 0 to the current frame.
962
Ronald Oussoren3075e162006-07-25 20:28:55 +0000963- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000964

967-------
968
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000969- Correction of patch #1455898: In the mbcs decoder, set final=False
970 for stream decoder, but final=True for the decode function.
971
Georg Brandl07fec3a2006-08-01 18:49:24 +0000972- os.urandom no longer masks unrelated exceptions like SystemExit or
973 KeyboardInterrupt.
974
Tim Peters4643c2f2006-08-10 22:45:34 +0000975- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000976 shutil.copytree on Windows
977
Georg Brandle34ac7c2006-07-30 11:07:23 +0000978- Bug #1002398: The documentation for os.path.sameopenfile now correctly
979 refers to file descriptors, not file objects.
980
Tim Peterscbdd3502006-09-05 01:47:53 +0000981- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000982 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000983 #1513611, and probably others.
984
Georg Brandledd9b0d2006-07-29 09:33:26 +0000985- Bug #1441397: The compiler module now recognizes module and function
986 docstrings correctly as it did in Python 2.4.
987
Tim Peters6f681472006-07-27 23:44:37 +0000988- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
989 lost that tests are sorted by name before being run. This rarely
990 matters for well-written tests, but can create baffling symptoms if
991 side effects from one test to the next affect outcomes. ``DocTestFinder``
992 has been changed to sort the list of tests it returns.
993
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000994- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000995 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000996
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000997- Bug #978833: Really close underlying socket in _socketobject.close.
998
Georg Brandldb232dc2006-08-20 13:15:43 +0000999- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1000 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001001
Georg Brandlcf0c1722006-07-26 07:23:32 +00001002- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1003 to recursive calls and call it with the failing package name.
1004
Martin v. Löwis0b483032006-07-25 09:53:12 +00001005- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1006
Georg Brandlc13c34c2006-07-24 14:09:56 +00001007- Patch #1515343: Fix printing of deprecated string exceptions with a
1008 value in the traceback module.
1009
Greg Ward48fae7a2006-07-23 16:05:51 +00001010- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1011
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001012- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1013
Brett Cannoncaebe222006-07-18 04:41:36 +00001014- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1015 argument tuple. For arguments where zero is illegal, the value is forced to
1016 the minimum value that is correct. This is to support an undocumented but
1017 common way people used to fill in inconsequential information in the time
1018 tuple pre-2.4.
1019
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001020- Patch #1220874: Update the binhex module for Mach-O.
1021
Barry Warsawb110bad2006-07-21 14:51:07 +00001022- The email package has improved RFC 2231 support, specifically for
1023 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1024 (name*0=<blah>) parameter continuations. This may change the types of
1025 values returned from email.message.Message.get_param() and friends.
1026 Specifically in some cases where non-encoded continuations were used,
1027 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1028 will just return the string (since non-encoded continuations don't have
1029 charset and language parts).
1030
1031 Also, whereas % values were decoded in all parameter continuations, they are
1032 now only decoded in encoded parameter parts.
1033
Ronald Oussoren3075e162006-07-25 20:28:55 +00001034- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1035
1036- Bug #1517996: IDLE now longer shows the default Tk menu when a
1037 path browser, class browser or debugger is the frontmost window on MacOS X
1038
Barry Warsaw00decd72006-07-27 23:43:15 +00001039- Patch #1520294: Support for getset and member descriptors in types.py,
1040 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1041 of an object against these built-in types and more importantly, for getting
1042 their docstrings printed in the interactive interpreter's help() function.
1043
Ronald Oussoren3075e162006-07-25 20:28:55 +00001044
Neal Norwitza1f10902006-07-12 07:28:29 +00001045Extension Modules
1046-----------------
1047
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001048- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1049 a socket operation on a socket with a timeout, the exception will be
1050 caught correctly. Previously, the exception was not caught.
1051
Thomas Heller1393d6a2006-07-28 21:43:20 +00001052- Patch #1529514: The _ctypes extension is now compiled on more
1053 openbsd target platforms.
1054
Tim Peters9cab5932006-07-28 00:30:00 +00001055- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1056 a memory leak, affecting pickles and deep copies.
1057
Tim Petersbc24eee2006-07-27 01:14:53 +00001058- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001059 Paul Eggert.
1060
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001061- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1062
Thomas Hellerce049a02006-07-14 17:51:14 +00001063- Patch #1521817: Index range checking on ctypes arrays containing
1064 exactly one element enabled again. This allows iterating over these
1065 arrays, without the need to check the array size before.
1066
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001067- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001068 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001069 /dev/null in certain cases; this is now fixed.
1070
Thomas Heller47d7a062006-07-12 08:43:47 +00001071- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1072 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001073
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001074- Because of a misspelled preprocessor symbol, ctypes was always
1075 compiled without thread support; this is now fixed.
1076
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001077- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1078 methods now allow their database parameter to be None as the
1079 sleepycat API allows.
1080
Matt Flemingec926502006-07-28 11:27:27 +00001081- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1082 bluetooth API compared with Linux and FreeBSD.
1083
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001084Tests
1085-----
1086
1087- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1088 how long the test file should take to play. Now accepts taking 2.93 secs
1089 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1090
Georg Brandl4793aa32006-07-28 18:31:39 +00001091- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1092 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1093 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001100Mac
1101---
1102
1103- PythonLauncher now works correctly when the path to the script contains
1104 characters that are treated specially by the shell (such as quotes).
1105
1106- Bug #1527397: PythonLauncher now launches scripts with the working directory
1107 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001108 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001109 expect.

1118-----------------
1119
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001120- Bug #1441486: The literal representation of -(sys.maxint - 1)
1121 again evaluates to a int object, not a long.
1122
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001123- Bug #1501934: The scope of global variables that are locally assigned
1124 using augmented assignment is now correctly determined.
1125
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001126- Bug #927248: Recursive method-wrapper objects can now safely
1127 be released.
1128
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001129- Bug #1417699: Reject locale-specific decimal point in float()
1130 and atof().
1131
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001132- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1133 omit a default "error" argument for NULL pointer. This allows
1134 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001135
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001136- Bug #1519018: 'as' is now validated properly in import statements.
1137
Neal Norwitz28746ab2006-07-09 22:14:42 +00001138- On 64 bit systems, int literals that use less than 64 bits are
1139 now ints rather than longs.
1140
Neal Norwitzed657552006-07-10 00:04:44 +00001141- Bug #1512814, Fix incorrect lineno's when code at module scope
1142 started after line 256.
1143
Tim Peters32a83612006-07-10 21:08:24 +00001144- New function ``sys._current_frames()`` returns a dict mapping thread
1145 id to topmost thread stack frame. This is for expert use, and is
1146 especially useful for debugging application deadlocks. The functionality
1147 was previously available in Fazal Majid's ``threadframe`` extension
1148 module, but it wasn't possible to do this in a wholly threadsafe way from
1149 an extension.

1155 VS 2003.
1156
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001157- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1158
Tim Peters32a83612006-07-10 21:08:24 +00001159- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001160 environment variable to be set in order to the SDK environment
1161 for finding the compiler, include files, etc.

1166
Thomas Woutersadd19112006-07-05 11:03:49 +00001167- string.Template() now correctly handles tuple-values. Previously,
1168 multi-value tuples would raise an exception and single-value tuples would
1169 be treated as the value they contain, instead.
1170
Martin v. Löwisede77f52006-07-03 13:01:35 +00001171- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1176
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001177- Bug #1514693: Update turtle's heading when switching between
1178 degrees and radians.
1179
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001180- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001181 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001182

1184 is created.
1185
Martin v. Löwis7596e832006-07-01 15:33:37 +00001186- Bug #1513223: .close() of a _socketobj now releases the underlying
1187 socket again, which then gets closed as it becomes unreferenced.
1188
Fred Drake10497c82006-06-29 02:57:48 +00001189- Bug #1504333: Make sgmllib support angle brackets in quoted
1190 attribute values.
1191
1192- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1193 sgmllib ('[' and ']' were not accepted).
1194
Georg Brandl1be63af2006-06-28 20:23:25 +00001195- Fix a bug in the turtle module's end_fill function.
1196
Brett Cannon53ab5b72006-06-22 16:49:14 +00001197- Bug #1510580: The 'warnings' module improperly required that a Warning
1198 category be either a types.ClassType and a subclass of Warning. The proper
1199 check is just that it is a subclass with Warning as the documentation states.
1200
Georg Brandlad29e632006-06-21 17:45:17 +00001201- The compiler module now correctly compiles the new try-except-finally
1202 statement (bug #1509132).
1203
Neal Norwitz60373cd2006-06-22 06:30:50 +00001204- The wsgiref package is now installed properly on Unix.
1205
Vinay Sajip28e57612006-07-01 10:45:20 +00001206- A bug was fixed in logging.config.fileConfig() which caused a crash on
1207 shutdown when fileConfig() was called multiple times.
1208
Gerhard Häring762fbd32006-07-02 17:48:30 +00001209- The sqlite3 module did cut off data from the SQLite database at the first
1210 null character before sending it to a custom converter. This has been fixed
1211 now.
1212
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001213Extension Modules
1214-----------------
1215
Tim Peters112aad32006-07-19 00:03:19 +00001216- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1217 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1218 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001219
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001220- Assigning None to pointer type fields in ctypes structures possible
1221 overwrote the wrong fields, this is fixed now.
1222
1223- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1224 on non-Windows platforms.
1225
1226- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1227 integer or long, without range checking.
1228
1229- Patch #1517790: It is now possible to use custom objects in the ctypes
1230 foreign function argtypes sequence as long as they provide a from_param
1231 method, no longer is it required that the object is a ctypes type.
1232
1233- The '_ctypes' extension module now works when Python is configured
1234 with the --without-threads option.
1235
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001236- Bug #1513646: os.access on Windows now correctly determines write
1237 access, again.
1238
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001239- Bug #1512695: cPickle.loads could crash if it was interrupted with
1240 a KeyboardInterrupt.
1241
Neal Norwitza12aa882006-07-06 06:45:08 +00001242- Bug #1296433: parsing XML with a non-default encoding and
1243 a CharacterDataHandler could crash the interpreter in pyexpat.
1244

1249
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001250- Automate Windows build process for the Win64 SSL module.
1251
Tim Peters32a83612006-07-10 21:08:24 +00001252- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001253 Previously, the slight difference could cause compilation errors of the
1254 'zlib' module on systems with more than one version of zlib.
1255
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001256- The MSI compileall step was fixed to also support a TARGETDIR

1275 documentation for the warnings module.
1276
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001277- Patch #1509163: MS Toolkit Compiler no longer available.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001286
1287Core and builtins
1288-----------------
1289
Georg Brandla56b9152006-06-19 06:35:54 +00001290- Patch #1507676: Error messages returned by invalid abstract object operations
1291 (such as iterating over an integer) have been improved and now include the
1292 type of the offending object to help with debugging.
1293
Brett Cannonea3912b2006-06-13 21:46:41 +00001294- Bug #992017: A classic class that defined a __coerce__() method that returned
1295 its arguments swapped would infinitely recurse and segfault the interpreter.
1296
Neal Norwitz909eb122006-06-12 02:13:21 +00001297- Fix the socket tests so they can be run concurrently.
1298
Neal Norwitzb9845e72006-06-12 02:11:18 +00001299- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001300 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001301
Brett Cannon22565aa2006-06-09 22:31:23 +00001302- Bug #532646: object.__call__() will continue looking for the __call__
1303 attribute on objects until one without one is found. This leads to recursion
1304 when you take a class and set its __call__ attribute to an instance of the
1305 class. Originally fixed for classic classes, but this fix is for new-style.
1306 Removes the infinite_rec_3 crasher.
1307
Georg Brandl24250812006-06-09 18:45:48 +00001308- The string and unicode methods startswith() and endswith() now accept
1309 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1310
Brett Cannonde3b0522006-06-08 17:00:45 +00001311- Buffer objects, at the C level, never used the char buffer
1312 implementation even when the char buffer for the wrapped object was
1313 explicitly requested (originally returned the read or write buffer).
1314 Now a TypeError is raised if the char buffer is not present but is
1315 requested.
1316
Georg Brandlddbaa662006-06-04 21:56:52 +00001317- Patch #1346214: Statements like "if 0: suite" are now again optimized
1318 away like they were in Python 2.4.
1319
Georg Brandlb7c8f542006-05-27 12:30:25 +00001320- Builtin exceptions are now full-blown new-style classes instead of
1321 instances pretending to be classes, which speeds up exception handling
1322 by about 80% in comparison to 2.5a2.
1323
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001324- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1325 Unicode 4.1.
1326
Georg Brandlf4ef1162006-05-26 18:03:31 +00001327- Patch #921466: sys.path_importer_cache is now used to cache valid and
1328 invalid file paths for the built-in import machinery which leads to
1329 fewer open calls on startup.
1330
Tim Peters696cf432006-05-24 21:10:40 +00001331- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1332 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1333 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1334 the number of input digits (it was and remains linear-time for bases
1335 2, 4, 8, 16 and 32).
1336
Tim Petersb713ec22006-05-23 18:45:30 +00001337- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1338 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1339 an integer close to ``sys.maxint``. This was repaired by patch
1340 #1335972, which also gives a nice speedup.
1341
Richard Jonescebbefc2006-05-23 18:28:17 +00001342- Patch #1337051: reduced size of frame objects.
1343
1344- PyErr_NewException now accepts a tuple of base classes as its
1345 "base" parameter.
1346
Richard Jones7c88dcc2006-05-23 10:37:38 +00001347- Patch #876206: function call speedup by retaining allocated frame
1348 objects.
1349
Georg Brandl7b90e162006-05-18 07:01:27 +00001350- Bug #1462152: file() now checks more thoroughly for invalid mode
1351 strings and removes a possible "U" before passing the mode to the
1352 C library function.
1353
Neal Norwitz1004a532006-05-15 07:17:23 +00001354- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1355
Neal Norwitz373f0a72006-05-15 07:04:36 +00001356- Bug #1487966: Fix SystemError with conditional expression in assignment
1357
Martin v. Löwis879768d2006-05-11 13:28:43 +00001358- WindowsError now has two error code attributes: errno, which carries
1359 the error values from errno.h, and winerror, which carries the error
1360 values from winerror.h. Previous versions put the winerror.h values
1361 (from GetLastError()) into the errno attribute.
1362
Martin v. Löwis77736712006-05-04 05:51:03 +00001363- Patch #1475845: Raise IndentationError for unexpected indent.
1364
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001365- Patch #1479181: split open() and file() from being aliases for each other.
1366
Tim Peters44bd9862006-06-01 13:49:23 +00001367- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1368 methods were always silently ignored by dictionaries when comparing keys.
1369 They are now passed through (except when using the C API function
1370 ``PyDict_GetItem()``, whose semantics did not change).
1371
1372- Bug #1456209: In some obscure cases it was possible for a class with a
1373 custom ``__eq__()`` method to confuse dict internals when class instances
1374 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1375 No, you don't have any code that did this ;-)

1383
Brett Cannon6ee7d012006-06-08 16:23:04 +00001384- Change binascii.hexlify to accept a read-only buffer instead of only a char
1385 buffer and actually follow its documentation.
1386
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001387- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1388
Nick Coghlanc649ec52006-05-29 12:43:05 +00001389- Patch #1478788 (modified version): The functional extension module has
1390 been renamed to _functools and a functools Python wrapper module added.
1391 This provides a home for additional function related utilities that are
1392 not specifically about functional programming. See PEP 309.
1393
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001394- Patch #1493701: performance enhancements for struct module.

1402 enabled builds on Windows and systems with Posix threads support.
1403
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001404- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1405 (up to the system limit of 32K characters).
1406
1407- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1408 As a result, these functions now raise WindowsError instead of OSError.
1409
Tim Peters7a822da2006-05-25 21:50:17 +00001410- ``time.clock()`` on Win64 should use the high-performance Windows
1411 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1412 Windows platforms).
1413
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001414- Calling Tk_Init twice is refused if the first call failed as that
1415 may deadlock.
1416
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001417- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1418 accept it without potentially using an uninitialized pointer.
1419
1420- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1421 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

1429
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001430- bsddb: the __len__ method of a DB object has been fixed to return correct
1431 results. It could previously incorrectly return 0 in some cases.
1432 Fixes SF bug 1493322 (pybsddb bug 1184012).
1433
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001434- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1435 aborts the db transaction safely when a modifier callback fails.
1436 Fixes SF python patch/bug #1408584.
1437
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001438- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001439 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001440 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1441 database calls that would previously deadlock. [SF python bug #775414]
1442

Tim Peters43898b42006-06-14 04:09:25 +00001473- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1474 guarantee that adjacent triples in the return list always describe
1475 non-adjacent blocks. Previously, a pair of matching blocks could end
1476 up being described by multiple adjacent triples that formed a partition
1477 of the matching pair.
1478
Greg Ward0e0c9f42006-06-11 16:24:11 +00001479- Bug #1498146: fix optparse to handle Unicode strings in option help,
1480 description, and epilog.
1481
Greg Wardd1c797e2006-06-11 14:42:41 +00001482- Bug #1366250: minor optparse documentation error.
1483
Greg Ward7f547402006-06-11 00:40:49 +00001484- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1485 clarify docs.
1486
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001487- The wsgiref package has been added to the standard library.
1488
Nick Coghlan676725d2006-06-08 13:54:49 +00001489- The functions update_wrapper() and wraps() have been added to the functools
1490 module. These make it easier to copy relevant metadata from the original
1491 function when writing wrapper functions.
1492
Tim Petersd6a9eef2006-06-05 01:48:21 +00001493- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1494 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001495
Martin v. Löwis3f767792006-06-04 19:36:28 +00001496- Patch #1359618: Speed up charmap encoder by using a trie structure
1497 for lookup.
1498
Tim Petersd609b1a2006-06-02 23:22:51 +00001499- The functions in the ``pprint`` module now sort dictionaries by key
1500 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1501 if and only if its display required more than one line, although that
1502 wasn't documented. The new behavior increases predictability; e.g.,
1503 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1504
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001505- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1506 (thanks for J. J. Lee).
1507
Georg Brandl2b330372006-05-28 20:23:12 +00001508- Patch #1496206: improve urllib2 handling of passwords with respect to
1509 default HTTP and HTTPS ports.
1510
George Yoshidaf3c65de2006-05-28 16:39:09 +00001511- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1512
Bob Ippolito7298f272006-05-23 18:43:47 +00001513- Patch #1281707: speed up gzip.readline.
1514
Georg Brandlb89316f2006-05-17 15:51:16 +00001515- Patch #1180296: Two new functions were added to the locale module:
1516 format_string() to get the effect of "format % items" but locale-aware,
1517 and currency() to format a monetary number with currency sign.
1518
Georg Brandle3a25832006-05-17 14:56:04 +00001519- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1520 and several features added, such as speed and geometry control.
1521
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001522- Patch #1488881: add support for external file objects in bz2 compressed
1523 tarfiles.
1524
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001525- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1526 stdout arguments, making it possible to redirect input and output
1527 for remote debugging.
1528
1529- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1530 a couple of issues, notably handling of long file names using the
1531 GNU LONGNAME extension.
1532
1533- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1534 new flag when ``name`` is already the name of an option flag.
1535
1536- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1537 package.
1538
1539- Patch #1472854: make the rlcompleter.Completer class usable on non-
1540 UNIX platforms.
1541
1542- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1543
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001544- Bug #1472827: correctly escape newlines and tabs in attribute values in
1545 the saxutils.XMLGenerator class.

1552
Martin v. Löwis222c5152006-06-03 07:37:13 +00001553- OpenBSD 3.9 is supported now.
1554
Martin v. Löwisa43190b2006-05-22 09:15:18 +00001555- Patch #1492356: Port to Windows CE.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001575What's New in Python 2.5 alpha 2?
1576=================================
1577
1578*Release date: 27-APR-2006*
1579
1580Core and builtins
1581-----------------
1582
Thomas Heller1b046642006-04-18 18:51:06 +00001583- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1584 by converting these apis from macros into exported functions again:
1585
1586 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1587 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1588 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1589 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1590 PyRun_String Py_CompileString
1591
Martin v. Löwis45294a92006-04-18 06:24:08 +00001592- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1593
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001594- All uses of PyStructSequence_InitType have been changed to initialize
1595 the type objects only once, even if the interpreter is initialized
1596 multiple times.
1597
Neal Norwitz61546162006-04-14 05:20:28 +00001598- Bug #1454485, array.array('u') could crash the interpreter. This was
1599 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1600 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1601
1602- Py_UNICODE is unsigned. It was always documented as unsigned, but
1603 due to a bug had a signed value in previous versions.
1604
Tim Peters3a5e8b12006-04-11 01:44:07 +00001605- Patch #837242: ``id()`` of any Python object always gives a positive
1606 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1607 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001608 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001609 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001610
Tim Peters3a5e8b12006-04-11 01:44:07 +00001611 def __hash__(self):
1612 return id(self) # WRONG
1613
1614 because a hash result must be a (short) Python int but it was always
1615 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001616 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001617 was always usable as a hash value before this patch. That's no longer
1618 necessarily so.
1619
1620- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001621 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001622 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001623 #1454844)
1624
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001625- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1626 involving generators that have paused outside of any ``try`` or ``with``
1627 blocks. (In 2.5a1, a paused generator that was part of a reference
1628 cycle could not be garbage collected, regardless of whether it was
1629 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001630
Anthony Baxter51bcb682006-04-05 14:51:42 +00001631Extension Modules

1633
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001634- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1635 is a macro.
1636
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001637- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1638 fails with an error condition.
1639
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001640- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1641
1642- Bug #1117761: bsddb.*open() no longer raises an exception when using
1643 the cachesize parameter.
1644
1645- Bug #1149413: bsddb.*open() no longer raises an exception when using
1646 a temporary db (file=None) with the 'n' flag to truncate on open.
1647
1648- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1649 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001650
Armin Rigoa9017c32006-04-19 11:50:27 +00001651- Patch #1062014: AF_UNIX sockets under Linux have a special
1652 abstract namespace that is now fully supported.

1656
Peter Astrand7d1d4362006-07-14 14:04:45 +00001657- Bug #1223937: subprocess.CalledProcessError reports the exit status
1658 of the process using the returncode attribute, instead of
1659 abusing errno.
1660
Tim Peters711bf302006-04-25 03:31:36 +00001661- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1662 a doctest to be skipped (the code is not run, and the expected output
1663 or exception is ignored).
1664
Nick Coghlanda2268f2006-04-24 04:37:15 +00001665- Fixed contextlib.nested to cope with exceptions being raised and
1666 caught inside exit handlers.
1667
Greg Wardab05edc2006-04-23 03:47:58 +00001668- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1669 hex, octal, or binary; add ``append_const`` action; keep going if
1670 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1671 added ``epilog`` for better help generation).
1672
Tim Peters21fbd572006-04-21 21:18:10 +00001673- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1674 called from a thread spawned as a side effect of importing a module.
1675
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001676- The pydoc module now supports documenting packages contained in
1677 .zip or .egg files.
1678
1679- The pkgutil module now has several new utility functions, such
1680 as ``walk_packages()`` to support working with packages that are either
1681 in the filesystem or zip files.
1682
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001683- The mailbox module can now modify and delete messages from
1684 mailboxes, in addition to simply reading them. Thanks to Gregory
1685 K. Johnson for writing the code, and to the 2005 Google Summer of
1686 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001687
Tim Petersc7605f22006-04-17 21:12:33 +00001688- The ``__del__`` method of class ``local`` in module ``_threading_local``
1689 returned before accomplishing any of its intended cleanup.
1690
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001691- Patch #790710: Add breakpoint command lists in pdb.
1692
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001693- Patch #1063914: Add Tkinter.Misc.clipboard_get().

1696
Anthony Baxtere29002c2006-04-12 12:07:31 +00001697- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1698 Windows. Bug #1469163.
1699
Phillip J. Eby47032112006-04-11 01:07:43 +00001700- The warnings, linecache, inspect, traceback, site, and doctest modules
1701 were updated to work correctly with modules imported from zipfiles or
1702 via other PEP 302 __loader__ objects.
1703
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001704- Patch #1467770: Reduce usage of subprocess._active to processes which
1705 the application hasn't waited on.

1712 direct output to an alternate file-like object.
1713

1715-----
1716
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001717- The Makefile now has a reindent target, which runs reindent.py on
1718 the library.
1719
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001720- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis0f48d982006-04-14 14:34:26 +00001724- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1725 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001726 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001727 CXX from --with-cxx-main, see description in README.
1728
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001729- Patch #1429775: Link extension modules with the shared libpython.
1730
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001731- Fixed a libffi build problem on MIPS systems.
1732
Tim Peters8931ff12006-05-13 23:28:20 +00001733- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1734 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1735 and "%zu" for unsigned integers of type ``size_t``.
1736
Anthony Baxter51bcb682006-04-05 14:51:42 +00001737Tests
1738-----
1739
Nick Coghlanda2268f2006-04-24 04:37:15 +00001740- test_contextlib now checks contextlib.nested can cope with exceptions
1741 being raised and caught inside exit handlers.
1742
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001743- test_cmd_line now checks operation of the -m and -c command switches
1744
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001745- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1746 it separately and by hand. It also wasn't cleaning up its changes to
1747 the current Decimal context.
1748
Thomas Woutersabd08882006-04-26 15:53:30 +00001749- regrtest.py now has a -M option to run tests that test the new limits of
1750 containers, on 64-bit architectures. Running these tests is only sensible
1751 on 64-bit machines with more than two gigabytes of memory. The argument
1752 passed is the maximum amount of memory for the tests to use.

Tim Petersb06d28c2006-05-12 01:57:59 +00001763- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1764
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001765- PEP 343: Added Context Types section to the library reference
1766 and attempted to bring other PEP 343 related documentation into
1767 line with the implementation and/or python-dev discussions.
1768
Tim Peters8dc73d22006-04-24 02:03:16 +00001769- Bug #1337990: clarified that ``doctest`` does not support examples

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001773What's New in Python 2.5 alpha 1?
1774=================================
1775
Anthony Baxterebed3f62006-04-03 15:03:44 +00001776*Release date: 05-APR-2006*

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001778Core and builtins
1779-----------------
1780
Nick Coghlan43832302006-04-23 17:04:07 +00001781- PEP 338: -m command line switch now delegates to runpy.run_module
1782 allowing it to support modules in packages and zipfiles
1783
Martin v. Löwisc661b882006-04-20 04:54:23 +00001784- On Windows, .DLL is not an accepted file name extension for
1785 extension modules anymore; extensions are only found if they
1786 end in .PYD.
1787
Martin v. Löwisea62d252006-04-03 10:56:49 +00001788- Bug #1421664: sys.stderr.encoding is now set to the same value as
1789 sys.stdout.encoding.
1790
Neal Norwitz92e212f2006-04-03 04:48:37 +00001791- __import__ accepts keyword arguments.
1792
Georg Brandlccadf842006-03-31 18:54:53 +00001793- Patch #1460496: round() now accepts keyword arguments.
1794
Anthony Baxter262c00a2006-03-30 10:53:17 +00001795- Fixed bug #1459029 - unicode reprs were double-escaped.
1796
Hye-Shik Changd478f342006-03-23 12:32:36 +00001797- Patch #1396919: The system scope threads are reenabled on FreeBSD
1798 5.4 and later versions.
1799
Neal Norwitze98ccf62006-03-23 05:39:47 +00001800- Bug #1115379: Compiling a Unicode string with an encoding declaration
1801 now gives a SyntaxError.
1802
Georg Brandlabd1ff82006-03-18 07:59:59 +00001803- Previously, Python code had no easy way to access the contents of a
1804 cell object. Now, a ``cell_contents`` attribute has been added
1805 (closes patch #1170323).
1806
Tim Peterscf79aac2006-03-16 01:14:46 +00001807- Patch #1123430: Python's small-object allocator now returns an arena to
1808 the system ``free()`` when all memory within an arena becomes unused
1809 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1810 freed. Some applications will see a drop in virtual memory size now,
1811 especially long-running applications that, from time to time, temporarily
1812 use a large number of small objects. Note that when Python returns an
1813 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001814 platform C library will in turn return that memory to the operating system.
1815 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001816 appears to be effective at least on Microsoft C and gcc-based systems.
1817 Thanks to Evan Jones for hard work and patience.
1818
Georg Brandl533ff6f2006-03-08 18:09:27 +00001819- Patch #1434038: property() now uses the getter's docstring if there is
1820 no "doc" argument given. This makes it possible to legitimately use
1821 property() as a decorator to produce a read-only property.
1822
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001823- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1824 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1825 of requiring an int or long in slicing and a few other contexts, enabling
1826 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1827
Neal Norwitz995acdf2006-03-07 05:01:00 +00001828- Fixed various bugs reported by Coverity's Prevent tool.
1829
Brett Cannonbf364092006-03-01 04:25:17 +00001830- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1831 new exception base class, BaseException, which has a new message attribute.
1832 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1833 Raising a string exception now raises a DeprecationWarning.
1834
Thomas Woutersfb609f42006-02-28 16:37:25 +00001835- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1836 explicitly relative, using 'from .module import name' to mean 'from the same
1837 package as this module is in. Imports without dots still default to the
1838 old relative-then-absolute, unless 'from __future__ import
1839 absolute_import' is used.
1840
Brett Cannona7446e32006-02-27 23:39:10 +00001841- Properly check if 'warnings' raises an exception (usually when a filter set
1842 to "error" is triggered) when raising a warning for raising string
1843 exceptions.
1844
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001845- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001846 The name was removed from Include/code.h.
1847
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001848- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001849
Guido van Rossum1968ad32006-02-25 22:38:04 +00001850- Patch 1433928:
1851 - The copy module now "copies" function objects (as atomic objects).
1852 - dict.__getitem__ now looks for a __missing__ hook before raising
1853 KeyError.
1854
Tim Peters84ef21c2006-02-28 20:39:06 +00001855- PEP 343: with statement implemented. Needs ``from __future__ import
1856 with_statement``. Use of 'with' as a variable will generate a warning.
1857 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001858 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001859 The following objects have __context__ methods:
1860 - The built-in file type.
1861 - The thread.LockType type.
1862 - The following types defined by the threading module:
1863 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1864 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001865
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001866- Fix the encodings package codec search function to only search
1867 inside its own package. Fixes problem reported in patch #1433198.
1868
1869 Note: Codec packages should implement and register their own
1870 codec search function. PEP 100 has the details.
1871
Tim Peters9ea89d22006-06-04 03:26:02 +00001872- PEP 353: Using ``Py_ssize_t`` as the index type.
1873
1874- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1875 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1876 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1877 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1878 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001879
Neal Norwitzfc76d632006-01-10 06:03:13 +00001880- Patch #1400181, fix unicode string formatting to not use the locale.
1881 This is how string objects work. u'%f' could use , instead of .
1882 for the decimal point. Now both strings and unicode always use periods.
1883
Neal Norwitz671b9e32006-01-09 07:07:12 +00001884- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1885 configure would break checking curses.h.
1886
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001887- Bug #959576: The pwd module is now builtin. This allows Python to be
1888 built on UNIX platforms without $HOME set.
1889
Neal Norwitzc10978f2005-12-19 06:07:16 +00001890- Bug #1072182, fix some potential problems if characters are signed.
1891
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001892- Bug #889500, fix line number on SyntaxWarning for global declarations.
1893
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001894- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1895
Neal Norwitze7214a12005-12-18 05:03:17 +00001896- Support for converting hex strings to floats no longer works.
1897 This was not portable. float('0x3') now raises a ValueError.
1898
Barry Warsaw2a38a862005-12-18 01:27:35 +00001899- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001900 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001901 is now displayed in interactive prompt banner.
1902
Georg Brandlfa166682005-12-17 21:45:17 +00001903- Implementation of PEP 341 - Unification of try/except and try/finally.
1904 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001905 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001906
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001907- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1908 now encodes backslash correctly.
1909
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001910- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1911
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001912- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001913 and long longs.
1914
Neal Norwitz67715f02005-11-09 06:59:35 +00001915- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001916 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001917 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001918
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001919- Replaced most Unicode charmap codecs with new ones using the
1920 new Unicode translate string feature in the builtin charmap
1921 codec; the codecs were created from the mapping tables available
1922 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1923 encodings now include a mapping for the Apple logo)
1924
Tim Peterse3547fd2005-12-16 23:13:57 +00001925- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001926
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001927- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001928
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001929- A new AST parser implementation was completed. The abstract
1930 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001931 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001932
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001933- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001934 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1935
Neal Norwitz708e51a2005-10-03 04:48:15 +00001936- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1937
Neal Norwitz11bd1192005-10-03 00:54:56 +00001938- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1939 Provide a warning when a directory is passed on the command line.
1940
Neal Norwitz40d37812005-10-02 01:48:49 +00001941- Fix segfault with invalid coding.
1942
1943- SF bug #772896: unknown encoding results in MemoryError.
1944
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001945- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001946 supported a __len__() method which evaluated to False when the iterator
1947 was empty.
1948
Guido van Rossum630db602005-09-20 18:49:54 +00001949- On 64-bit platforms, when __len__() returns a value that cannot be
1950 represented as a C int, raise OverflowError.
1951
Skip Montanarof8948ca2005-09-19 03:54:46 +00001952- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001953 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001954
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001955- SF bug #893549: parsing keyword arguments was broken with a few format
1956 codes.
1957
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001958- Changes donated by Elemental Security to make it work on AIX 5.3
1959 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1960 bug #105470: test_pwd fails on 64bit system (Opteron).
1961
Guido van Rossum539c6622005-09-14 17:49:54 +00001962- Changes donated by Elemental Security to make it work on HP-UX 11 on
1963 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1964
Georg Brandl4550b8d2005-08-26 06:43:52 +00001965- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001966 (fixes bug #1119418).
1967
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001968- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1969
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001970- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1971 exceptions that cause a function to exit.
1972
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001973- The implementation of set() and frozenset() was revised to use its
1974 own internal data structure. Memory consumption is reduced by 1/3
1975 and there are modest speed-ups as well. The API is unchanged.
1976
Tim Petersde7990b2005-07-17 23:45:23 +00001977- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1978
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001979- SF bug #1229429: PyObject_CallMethod failed to decrement some
1980 reference counts in some error exit cases.
1981
Tim Petersecc6e6a2005-07-10 22:30:55 +00001982- SF bug #1185883: Python's small-object memory allocator took over
1983 a block managed by the platform C library whenever a realloc specified
1984 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001985 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001986 portable way to copy data from the C-managed block into Python's
1987 small-object space without risking a memory fault. Python's small-object
1988 realloc now leaves such blocks under the control of the platform C
1989 realloc.
1990
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001991- SF bug #1232517: An overflow error was not detected properly when
1992 attempting to convert a large float to an int in os.utime().
1993
Raymond Hettinger3296e692005-06-29 23:29:56 +00001994- SF bug #1224347: hex longs now print with lowercase letters just
1995 like their int counterparts.
1996
Michael W. Hudson188d4362005-06-20 16:52:57 +00001997- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1998 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1999 interpreter states; back out that fix and do a better job (see
2000 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2001 for a longer write-up of the problem).
2002
Michael W. Hudsondf888462005-06-03 14:41:55 +00002003- SF patch #1180995: marshal now uses a binary format by default when
2004 serializing floats.
2005
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002006- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2007 the routines that promise to produce IEEE 754 binary representations
2008 of floats now simply copy bytes around.
2009
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002010- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2011 278.
2012
Brett Cannonc3647ac2005-04-26 03:45:26 +00002013- patch #1109424: int, long, float, complex, and unicode now check for the
2014 proper magic slot for type conversions when subclassed. Previously the
2015 magic slot was ignored during conversion. Semantics now match the way
2016 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002017 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002018 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002019 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002020
Barry Warsawc8d907c2005-04-19 23:43:40 +00002021- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2022 NULL, now raise an AttributeError when attempting to set or delete the
2023 attribute. Previously a TypeError was raised, but this was inconsistent
2024 with the equivalent pure-Python implementation.
2025
Michael W. Hudson774479c2005-04-18 08:46:17 +00002026- It is now safe to call PyGILState_Release() before
2027 PyEval_InitThreads() (note that if there is reason to believe there
2028 are multiple threads around you still must call PyEval_InitThreads()
2029 before using the Python API; this fix is for extension modules that
2030 have no way of knowing if Python is multi-threaded yet).
2031
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002032- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2033 disabled caused a crash.
2034
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002035- Bug #1165306: instancemethod_new allowed the creation of a method
2036 with im_class == im_self == NULL, which caused a crash when called.
2037
Tim Petersecc6e6a2005-07-10 22:30:55 +00002038- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002039 fixes the crash seen in bug #1165761
2040
Raymond Hettinger96229b12005-03-11 06:49:40 +00002041- Added two new builtins, any() and all().
2042
Brett Cannon409d8f22005-03-05 06:47:57 +00002043- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002044 (e.g., ``class C(): pass`` is no longer a syntax error).
2045 Patch #1176012 added support to the 'parser' module and 'compiler' package
2046 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002047

2086 can't help, but can hurt if another thread happens to get created with
2087 the same thread id).

2295 in attribute values.
2296
Anthony Baxterc51ee692006-04-01 00:57:31 +00002297- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002298 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002299 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002300 module will not be built.

Tim Petersc17976e2006-04-01 00:26:53 +00002302- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2303 aren't officially supported here, and trying to use them will probably

2325
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002326- email 4.0 package now integrated. This is largely the same as the email 3.0
2327 package that was included in Python 2.3, except that PEP 8 module names are
2328 now used (e.g. mail.message instead of email.Message). The MIME classes
2329 have been moved to a subpackage (e.g. email.mime.text instead of
2330 email.MIMEText). The old names are still supported for now. Several
2331 deprecated Message methods have been removed and lots of bugs have been
2332 fixed. More details can be found in the email package documentation.

2335 (a subclass of tuple) that provides incremental decoders and encoders
2336 (a way to use stateful codecs without the stream API). Python functions
2337 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2338 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2339 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002340
Walter Dörwald067db482006-03-15 22:17:27 +00002341- Patch #1359365: Calling next() on a closed StringIO.String object raises
2342 a ValueError instead of a StopIteration now (like file and cString.String do).
2343 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2344 called before (like file and StringIO.StringIO do).

Tim Peterse3547fd2005-12-16 23:13:57 +00002418 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2419 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2420 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2421 Ronald L. Rivest offered this advice for Python:
2422
2423 "The consensus of researchers in this area (at least as
2424 expressed at the NIST Hash Function Workshop 10/31/05),
2425 is that SHA-256 is a good choice for the time being, but
2426 that research should continue, and other alternatives may
2427 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002428
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002429- Added a subset of Fredrik Lundh's ElementTree package. Available

2587
Guido van Rossumd0641422005-02-03 15:01:24 +00002588- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2589 disables recursive traversal through instance attributes, which can
2590 be exploited in various ways.
2591
Tim Peterse3547fd2005-12-16 23:13:57 +00002592- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002593 flags on the HTTP listening socket.
2594
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002595- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2596 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2597
Fred Drakefbdeaad2006-07-29 16:56:15 +00002598- Patches #893642, #1039083: add allow_none, encoding arguments to
2599 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002600

Thomas Hellerd6c6e222005-01-20 19:20:16 +00002603- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2604
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002605- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2606
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002607- Enhancements to the csv module:
2608
2609 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002610 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002611 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002612 + Dialect parameter parsing has been re-implemented to improve error
2613 reporting.
2614 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2615 dictates.
2616 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002617 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002618 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002619 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2620 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002621 + reader now allows \r characters to be quoted (previously it only allowed
2622 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002623 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002624 + Dialect classes passed to the module are no longer instantiated by
2625 the module before being parsed (the former validation scheme required
2626 this, but the mechanism was unreliable).
2627 + The dialect registry now contains instances of the internal
2628 C-coded dialect type, rather than references to python objects.
2629 + the internal c-coded dialect type is now immutable.
2630 + register_dialect now accepts the same keyword dialect specifications
2631 as the reader and writer, allowing the user to register dialects
2632 without first creating a dialect class.
2633 + a configurable limit to the size of parsed fields has been added -
2634 previously, an unmatched quote character could result in the entire
2635 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002636 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002637 the parser field size limit (returning the former limit). The initial
2638 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002639 + A line_num attribute has been added to the reader object, which tracks
2640 the number of lines read from the source iterator. This is not
2641 the same as the number of records returned, as records can span
2642 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002643 + reader and writer objects were not being registered with the cyclic-GC.
2644 This has been fixed.
2645
Brett Cannone6539c42005-01-08 02:43:53 +00002646- _DummyThread objects in the threading module now delete self.__block that is
2647 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2648 lock primitives tend to be limited in number and thus should not be wasted on
2649 a _DummyThread object. Fixes bug #1089632.
2650
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002651- The imghdr module now detects Exif files.
2652
Raymond Hettinger6065d322004-12-20 23:51:53 +00002653- StringIO.truncate() now correctly adjusts the size attribute.
2654 (Bug #951915).
2655
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002656- locale.py now uses an updated locale alias table (built using
2657 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2658 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002659 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002660
Raymond Hettinger3557f422004-12-07 12:02:02 +00002661- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2662
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002663- the pickle module no longer accepts the deprecated None option in the
2664 args tuple returned by __reduce__().
2665
Brett Cannon84667c02004-12-07 03:25:18 +00002666- optparse now optionally imports gettext. This allows its use in setup.py.
2667
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002668- the pickle module no longer uses the deprecated bin parameter.
2669
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002670- the shelve module no longer uses the deprecated binary parameter.
2671
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002672- the pstats module no longer uses the deprecated ignore() method.
2673
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002674- the filecmp module no longer uses the deprecated use_statcache argument.
2675
Raymond Hettinger664347b2004-12-04 21:21:53 +00002676- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2677 extended or overridden by subclasses. Formerly, the subclassed method would
2678 be ignored by the rest of the module. (Bug #1078905).
2679
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002680- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002681 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002682
Walter Dörwald36733692004-12-22 12:50:50 +00002683- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2684 once when a size argument is given. This prevents a buffer overflow in the
2685 tokenizer with very long source lines.
2686
Barry Warsaw538561e2006-01-01 21:48:54 +00002687- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2688 immediately after creating the object, without any intervening
2689 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002690
Skip Montanaro05885812005-01-16 20:48:27 +00002691- The reconvert.quote function can now emit triple-quoted strings. The
2692 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002693
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002694- ``UserString.MutableString`` now supports negative indices in
2695 ``__setitem__`` and ``__delitem__``
2696
Greg Ward40407942005-03-05 02:53:17 +00002697- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2698 correctly.
2699
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002700- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2701 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2702 character even if the user has passed a size parameter to get a proper
2703 line ending. Remove the special handling of a "\r\n" that has been split
2704 between two lines.
2705
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002706- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2707 about illegal code points. The codec now supports PEP 293 style error
2708 handlers.
2709
Walter Dörwald78a78b02005-09-01 12:04:29 +00002710- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002711 from the input stream, so that the output is a byte string in the correct
2712 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002713
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002714- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2715 considering it exactly like a '*'.
2716
Walter Dörwald007f8df2005-10-09 19:42:27 +00002717- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2718 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002719
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002720- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2721
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002722- Patch #1413711: Certain patterns of differences were making difflib
2723 touch the recursion limit.
2724
Walter Dörwald58917a62006-03-31 15:26:22 +00002725- Bug #947906: An object oriented interface has been added to the calendar
2726 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002727 called as a script (e.g. via ``python -mcalendar``). Localized month and
2728 weekday names can be ouput (even if an exotic encoding is used) using
2729 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002730
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002731Build
2732-----
2733
Neal Norwitz602d3392006-03-31 08:21:40 +00002734- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2735 by using -mieee gcc option.
2736

2738
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002739- Build support for Win64-AMD64 was added.
2740
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002741- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2742
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002743- Patch #881820: look for openpty and forkpty also in libbsd.
2744
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002745- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2746 The zlib module is now builtin on Windows.
2747
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002748- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2749
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002750- Bug #1189330: configure did not correctly determine the necessary
2751 value of LINKCC if python was built with GCC 4.0.
2752
Trent Mick8321b422005-07-26 02:29:21 +00002753- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2754 vulnerability in zlib 1.2.1 and 1.2.2.
2755
Brett Cannon08cd5982005-04-24 22:26:38 +00002756- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2757 flags that change binary compatibility. Changes were also made to
2758 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002759 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002760
Bob Ippolitoed233462005-03-29 13:47:59 +00002761- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2762 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2763 no longer exists). This configure patch makes things right.
2764
Martin v. Löwise2713be2005-03-08 15:03:08 +00002765- Bug #1158607: Build with --disable-unicode again.
2766
Brett Cannon46d96232005-02-16 00:07:19 +00002767- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2768 defined. Discovered as a result of not being able to build on OS X.
2769
Brett Cannon516592f2004-12-07 00:42:59 +00002770- setup.py now uses the directories specified in LDFLAGS using the -L option
2771 and in CPPFLAGS using the -I option for adding library and include
2772 directories, respectively, for compiling extension modules against. This has
2773 led to the core being compiled using the values in CPPFLAGS. It also removes
2774 the need for the special-casing of both DarwinPorts and Fink for darwin since
2775 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2776 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2777 Fink, ``-I/opt/local/include`` for DarwinPorts).
2778
Brett Cannon43802422005-02-10 20:48:03 +00002779- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2780 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2781 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2782 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002784C API
2785-----
2786
Tim Petersc9d78aa2006-03-26 23:27:58 +00002787- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2788 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2789 is obtained via the ``PyObject_`` family, it must be released via the
2790 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2791 always been officially true, but when Python's small-object allocator was
2792 introduced, an attempt was made to cater to a few extension modules
2793 discovered at the time that obtained memory via ``PyObject_New`` but
2794 released it via ``PyMem_DEL``. It's years later, and if such code still
2795 exists it will fail now (probably with segfaults, but calling wrong
2796 low-level memory management functions can yield many symptoms).
2797
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002798- Added a C API for set and frozenset objects.
2799
Raymond Hettinger66517482004-12-03 11:45:13 +00002800- Removed PyRange_New().
2801
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002802- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2803 mapping argument now. This string is used as a mapping table. Byte values
2804 greater than the length of the string and 0xFFFE are treated as undefined
2805 mappings.
