619-----------------
620
Neal Norwitz0bcafac2006-09-11 08:51:17 +0000621- Make _PyGILState_NoteThreadState() static, it was not used anywhere
622 outside of pystate.c and should not be necessary.
623
Brett Cannon19d76c52006-09-09 07:18:44 +0000624- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
625 allows calling unicode() on exceptions classes directly to succeed.
626
Georg Brandlecab6232006-09-06 06:47:02 +0000627- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
628 Also make sure that every exception class has __module__ set to
629 'exceptions'.
630
Georg Brandl37a9e572006-09-06 06:09:34 +0000631- Bug #1550983: emit better error messages for erroneous relative

633
Tim Peterscbdd3502006-09-05 01:47:53 +0000634- Overflow checking code in integer division ran afoul of new gcc
635 optimizations. Changed to be more standard-conforming.

Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000642- The return tuple from str.rpartition(sep) is (tail, sep, head) where
643 head is the original string if sep was not found.
644
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000645- Bug #1520864: unpacking singleton tuples in list comprehensions and
646 generator expressions (x for x, in ... ) works again. Fixing this problem
647 required changing the .pyc magic number. This means that .pyc files
648 generated before 2.5c2 will be regenerated.

760Core and builtins
761-----------------
762
Neal Norwitz24b6f202006-09-05 04:43:56 +0000763- Fix infinite recursion when subclassing long and overriding __hash__.
764
765- Fix concatenation (+=) of long strings.
766
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000767- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000768 compared equal or unequal to a string and a UnicodeDecodeError
769 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000770
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000771 Instead, the equal (==) and unequal (!=) comparison operators will
772 now issue a UnicodeWarning and interpret the two objects as
773 unequal. The UnicodeWarning can be filtered as desired using
774 the warning framework, e.g. silenced completely, turned into an
775 exception, logged, etc.
776
777 Note that compare operators other than equal and unequal will still
778 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000779
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000780- Fix segfault when doing string formatting on subclasses of long.
781
782- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
783 with new-style classes.
784
785- Fix bug related to __len__ functions returning negative values with
786 classic classes.
787
788- Patch #1538606, Fix __index__() clipping. There were some problems
789 discovered with the API and how integers that didn't fit into Py_ssize_t
790 were handled. This patch attempts to provide enough alternatives
791 to effectively use __index__.
792
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000793- Bug #1536021: __hash__ may now return long int; the final hash
794 value is obtained by invoking hash on the long int.
795
Thomas Hellerab1049c2006-08-08 17:37:00 +0000796- Bug #1536786: buffer comparison could emit a RuntimeWarning.
797
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000798- Bug #1535165: fixed a segfault in input() and raw_input() when
799 sys.stdin is closed.
800
Thomas Heller74d36f02006-08-04 18:17:40 +0000801- On Windows, the PyErr_Warn function is now exported from
802 the Python dll again.
803
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000804- Bug #1191458: tracing over for loops now produces a line event
805 on each iteration. Fixing this problem required changing the .pyc
806 magic number. This means that .pyc files generated before 2.5c1
807 will be regenerated.
808
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000809- Bug #1333982: string/number constants were inappropriately stored
810 in the byte code and co_consts even if they were not used, ie
811 immediately popped off the stack.
812
Georg Brandle9462c72006-08-04 18:03:37 +0000813- Fixed a reference-counting problem in property().

817-------
818
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000819- Fix a bug in the ``compiler`` package that caused invalid code to be
820 generated for generator expressions.
821
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000822- The distutils version has been changed to 2.5.0. The change to
823 keep it programmatically in sync with the Python version running
824 the code (introduced in 2.5b3) has been reverted. It will continue
825 to be maintained manually as static string literal.
826
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000827- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000828 and this cannot be converted to the required C type, an exception is
829 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000830 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000831
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000832- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000833 an exception.
834
Tim Peterscbdd3502006-09-05 01:47:53 +0000835- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000836 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000837 workarounds for clocks with low resolution, to stop the code yielding
838 duplicate UUIDs.
839
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000840- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
841 before raising SystemExit, allowing IDLE to honor quit() and exit().
842
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000843- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
844
Georg Brandl7a1af772006-08-14 21:55:28 +0000845- Patch #1536071: trace.py should now find the full module name of a
846 file correctly even on Windows.
847
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000848- logging's atexit hook now runs even if the rest of the module has
849 already been cleaned up.
850
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000851- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000852
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000853- Bug #1531405, format_exception no longer raises an exception if
854 str(exception) raised an exception.
855
Neil Schemenauer06ded092006-08-04 16:20:30 +0000856- Fix a bug in the ``compiler`` package that caused invalid code to be
857 generated for nested functions.

869
Thomas Heller1ce433e2006-08-14 16:20:04 +0000870- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
871 '-no-stack-protector' compiler flag for OpenBSD has been removed.
872
Thomas Heller86720042006-08-14 11:17:48 +0000873- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
874 uses the _as_parameter_ attribute when objects are passed to foreign
875 function calls. The ctypes version number was changed to 1.0.1.
876
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000877- Bug #1530559, struct.pack raises TypeError where it used to convert.
878 Passing float arguments to struct.pack when integers are expected
879 now triggers a DeprecationWarning.

917
Tim Peters4643c2f2006-08-10 22:45:34 +0000918- Bug #1069160. Internal correctness changes were made to
919 ``PyThreadState_SetAsyncExc()``. A test case was added, and
920 the documentation was changed to state that the return value
921 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +0000924What's New in Python 2.5 beta 3?
925================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000926
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000927*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000928
929Core and builtins
930-----------------
931
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000932- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000933 returned a long (see PEP 353).
934
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000935- Bug #1515471: string.replace() accepts character buffers again.
936
Neal Norwitz07aadb12006-07-30 06:55:48 +0000937- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
938 This provides the proper warning for struct.pack().
939 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
940
Neal Norwitz0d62a062006-07-30 06:53:31 +0000941- Patch #1531113: Fix augmented assignment with yield expressions.
942 Also fix a SystemError when trying to assign to yield expressions.
943
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000944- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
945 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
946 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
947 excessive filesystem operations during imports.
948
Tim Petersbc24eee2006-07-27 01:14:53 +0000949- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
950 operations on signed longs that are formally undefined by C.
951 Unfortunately, at least one compiler now cares about that, so complicated
952 the code to make that compiler happy again.
953
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000954- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
955
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000956- Patch #1232023: Stop including current directory in search
957 path on Windows.
958
Neal Norwitze1fdb322006-07-21 05:32:28 +0000959- Fix some potential crashes found with failmalloc.
960
Neal Norwitze7563102006-07-17 01:00:16 +0000961- Fix warnings reported by Klocwork's static analysis tool.
962
Neal Norwitz84be93b2006-07-16 01:50:38 +0000963- Bug #1512814, Fix incorrect lineno's when code within a function
964 had more than 255 blank lines.
965
Georg Brandl9dceedb2006-07-12 15:31:17 +0000966- Patch #1521179: Python now accepts the standard options ``--help`` and
967 ``--version`` as well as ``/?`` on Windows.
968
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000969- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000970 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000971 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000972
Tim Peters112aad32006-07-19 00:03:19 +0000973- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000974 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000975 new ``sys._current_frames()`` returns a dictionary with one entry,
976 mapping the faux "thread id" 0 to the current frame.
977
Ronald Oussoren3075e162006-07-25 20:28:55 +0000978- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000979

Neal Norwitza1f10902006-07-12 07:28:29 +0000981Library
982-------
983
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000984- Correction of patch #1455898: In the mbcs decoder, set final=False
985 for stream decoder, but final=True for the decode function.
986
Georg Brandl07fec3a2006-08-01 18:49:24 +0000987- os.urandom no longer masks unrelated exceptions like SystemExit or
988 KeyboardInterrupt.
989
Tim Peters4643c2f2006-08-10 22:45:34 +0000990- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000991 shutil.copytree on Windows
992
Georg Brandle34ac7c2006-07-30 11:07:23 +0000993- Bug #1002398: The documentation for os.path.sameopenfile now correctly
994 refers to file descriptors, not file objects.
995
Tim Peterscbdd3502006-09-05 01:47:53 +0000996- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000997 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000998 #1513611, and probably others.
999
Georg Brandledd9b0d2006-07-29 09:33:26 +00001000- Bug #1441397: The compiler module now recognizes module and function
1001 docstrings correctly as it did in Python 2.4.
1002
Tim Peters6f681472006-07-27 23:44:37 +00001003- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1004 lost that tests are sorted by name before being run. This rarely
1005 matters for well-written tests, but can create baffling symptoms if
1006 side effects from one test to the next affect outcomes. ``DocTestFinder``
1007 has been changed to sort the list of tests it returns.
1008
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001009- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001010 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001011
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001012- Bug #978833: Really close underlying socket in _socketobject.close.
1013
Georg Brandldb232dc2006-08-20 13:15:43 +00001014- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1015 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001016
Georg Brandlcf0c1722006-07-26 07:23:32 +00001017- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1018 to recursive calls and call it with the failing package name.
1019
Martin v. Löwis0b483032006-07-25 09:53:12 +00001020- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1021
Georg Brandlc13c34c2006-07-24 14:09:56 +00001022- Patch #1515343: Fix printing of deprecated string exceptions with a
1023 value in the traceback module.
1024
Greg Ward48fae7a2006-07-23 16:05:51 +00001025- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1026
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001027- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1028
Brett Cannoncaebe222006-07-18 04:41:36 +00001029- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1030 argument tuple. For arguments where zero is illegal, the value is forced to
1031 the minimum value that is correct. This is to support an undocumented but
1032 common way people used to fill in inconsequential information in the time
1033 tuple pre-2.4.
1034
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001035- Patch #1220874: Update the binhex module for Mach-O.
1036
Barry Warsawb110bad2006-07-21 14:51:07 +00001037- The email package has improved RFC 2231 support, specifically for
1038 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1039 (name*0=<blah>) parameter continuations. This may change the types of
1040 values returned from email.message.Message.get_param() and friends.
1041 Specifically in some cases where non-encoded continuations were used,
1042 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1043 will just return the string (since non-encoded continuations don't have
1044 charset and language parts).
1045
1046 Also, whereas % values were decoded in all parameter continuations, they are
1047 now only decoded in encoded parameter parts.
1048
Ronald Oussoren3075e162006-07-25 20:28:55 +00001049- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1050
1051- Bug #1517996: IDLE now longer shows the default Tk menu when a
1052 path browser, class browser or debugger is the frontmost window on MacOS X
1053
Barry Warsaw00decd72006-07-27 23:43:15 +00001054- Patch #1520294: Support for getset and member descriptors in types.py,
1055 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1056 of an object against these built-in types and more importantly, for getting
1057 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001060Extension Modules
1061-----------------
1062
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001063- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1064 a socket operation on a socket with a timeout, the exception will be
1065 caught correctly. Previously, the exception was not caught.
1066
Thomas Heller1393d6a2006-07-28 21:43:20 +00001067- Patch #1529514: The _ctypes extension is now compiled on more
1068 openbsd target platforms.
1069
Tim Peters9cab5932006-07-28 00:30:00 +00001070- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1071 a memory leak, affecting pickles and deep copies.
1072
Tim Petersbc24eee2006-07-27 01:14:53 +00001073- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001074 Paul Eggert.
1075
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001076- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1077
Thomas Hellerce049a02006-07-14 17:51:14 +00001078- Patch #1521817: Index range checking on ctypes arrays containing
1079 exactly one element enabled again. This allows iterating over these
1080 arrays, without the need to check the array size before.
1081
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001082- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001083 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001084 /dev/null in certain cases; this is now fixed.
1085
Thomas Heller47d7a062006-07-12 08:43:47 +00001086- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1087 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001088
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001089- Because of a misspelled preprocessor symbol, ctypes was always
1090 compiled without thread support; this is now fixed.
1091
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001092- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1093 methods now allow their database parameter to be None as the
1094 sleepycat API allows.
1095
Matt Flemingec926502006-07-28 11:27:27 +00001096- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1097 bluetooth API compared with Linux and FreeBSD.
1098
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001099Tests
1100-----
1101
1102- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1103 how long the test file should take to play. Now accepts taking 2.93 secs
1104 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1105
Georg Brandl4793aa32006-07-28 18:31:39 +00001106- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1107 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1108 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001115Mac
1116---
1117
1118- PythonLauncher now works correctly when the path to the script contains
1119 characters that are treated specially by the shell (such as quotes).
1120
1121- Bug #1527397: PythonLauncher now launches scripts with the working directory
1122 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001123 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001124 expect.

1133-----------------
1134
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001135- Bug #1441486: The literal representation of -(sys.maxint - 1)
1136 again evaluates to a int object, not a long.
1137
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001138- Bug #1501934: The scope of global variables that are locally assigned
1139 using augmented assignment is now correctly determined.
1140
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001141- Bug #927248: Recursive method-wrapper objects can now safely
1142 be released.
1143
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001144- Bug #1417699: Reject locale-specific decimal point in float()
1145 and atof().
1146
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001147- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1148 omit a default "error" argument for NULL pointer. This allows
1149 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001150
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001151- Bug #1519018: 'as' is now validated properly in import statements.
1152
Neal Norwitz28746ab2006-07-09 22:14:42 +00001153- On 64 bit systems, int literals that use less than 64 bits are
1154 now ints rather than longs.
1155
Neal Norwitzed657552006-07-10 00:04:44 +00001156- Bug #1512814, Fix incorrect lineno's when code at module scope
1157 started after line 256.
1158
Tim Peters32a83612006-07-10 21:08:24 +00001159- New function ``sys._current_frames()`` returns a dict mapping thread
1160 id to topmost thread stack frame. This is for expert use, and is
1161 especially useful for debugging application deadlocks. The functionality
1162 was previously available in Fazal Majid's ``threadframe`` extension
1163 module, but it wasn't possible to do this in a wholly threadsafe way from
1164 an extension.

1170 VS 2003.
1171
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001172- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1173
Tim Peters32a83612006-07-10 21:08:24 +00001174- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001175 environment variable to be set in order to the SDK environment
1176 for finding the compiler, include files, etc.

1181
Thomas Woutersadd19112006-07-05 11:03:49 +00001182- string.Template() now correctly handles tuple-values. Previously,
1183 multi-value tuples would raise an exception and single-value tuples would

Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001197
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001198- Bug #1514703: Only setup canvas window in turtle when the canvas
1199 is created.
1200
Martin v. Löwis7596e832006-07-01 15:33:37 +00001201- Bug #1513223: .close() of a _socketobj now releases the underlying
1202 socket again, which then gets closed as it becomes unreferenced.
1203
Fred Drake10497c82006-06-29 02:57:48 +00001204- Bug #1504333: Make sgmllib support angle brackets in quoted
1205 attribute values.
1206
1207- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1208 sgmllib ('[' and ']' were not accepted).
1209

1211
Brett Cannon53ab5b72006-06-22 16:49:14 +00001212- Bug #1510580: The 'warnings' module improperly required that a Warning
1213 category be either a types.ClassType and a subclass of Warning. The proper
1214 check is just that it is a subclass with Warning as the documentation states.
1215
Georg Brandlad29e632006-06-21 17:45:17 +00001216- The compiler module now correctly compiles the new try-except-finally
1217 statement (bug #1509132).
1218
Neal Norwitz60373cd2006-06-22 06:30:50 +00001219- The wsgiref package is now installed properly on Unix.
1220

1222 shutdown when fileConfig() was called multiple times.
1223
Gerhard Häring762fbd32006-07-02 17:48:30 +00001224- The sqlite3 module did cut off data from the SQLite database at the first
1225 null character before sending it to a custom converter. This has been fixed
1226 now.
1227
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001228Extension Modules
1229-----------------
1230
Tim Peters112aad32006-07-19 00:03:19 +00001231- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1232 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1233 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001234
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001235- Assigning None to pointer type fields in ctypes structures possible
1236 overwrote the wrong fields, this is fixed now.
1237
1238- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1239 on non-Windows platforms.
1240
1241- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1242 integer or long, without range checking.
1243
1244- Patch #1517790: It is now possible to use custom objects in the ctypes
1245 foreign function argtypes sequence as long as they provide a from_param
1246 method, no longer is it required that the object is a ctypes type.
1247
1248- The '_ctypes' extension module now works when Python is configured
1249 with the --without-threads option.
1250
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001251- Bug #1513646: os.access on Windows now correctly determines write
1252 access, again.
1253
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001254- Bug #1512695: cPickle.loads could crash if it was interrupted with
1255 a KeyboardInterrupt.
1256

1263-----
1264
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001265- Automate Windows build process for the Win64 SSL module.
1266
Tim Peters32a83612006-07-10 21:08:24 +00001267- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001268 Previously, the slight difference could cause compilation errors of the
1269 'zlib' module on systems with more than one version of zlib.
1270
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001271- The MSI compileall step was fixed to also support a TARGETDIR

1302Core and builtins
1303-----------------
1304
Georg Brandla56b9152006-06-19 06:35:54 +00001305- Patch #1507676: Error messages returned by invalid abstract object operations
1306 (such as iterating over an integer) have been improved and now include the
1307 type of the offending object to help with debugging.
1308
Brett Cannonea3912b2006-06-13 21:46:41 +00001309- Bug #992017: A classic class that defined a __coerce__() method that returned
1310 its arguments swapped would infinitely recurse and segfault the interpreter.
1311
Neal Norwitz909eb122006-06-12 02:13:21 +00001312- Fix the socket tests so they can be run concurrently.
1313
Neal Norwitzb9845e72006-06-12 02:11:18 +00001314- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001315 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001316
Brett Cannon22565aa2006-06-09 22:31:23 +00001317- Bug #532646: object.__call__() will continue looking for the __call__
1318 attribute on objects until one without one is found. This leads to recursion
1319 when you take a class and set its __call__ attribute to an instance of the
1320 class. Originally fixed for classic classes, but this fix is for new-style.
1321 Removes the infinite_rec_3 crasher.
1322
Georg Brandl24250812006-06-09 18:45:48 +00001323- The string and unicode methods startswith() and endswith() now accept
1324 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1325
Brett Cannonde3b0522006-06-08 17:00:45 +00001326- Buffer objects, at the C level, never used the char buffer
1327 implementation even when the char buffer for the wrapped object was
1328 explicitly requested (originally returned the read or write buffer).
1329 Now a TypeError is raised if the char buffer is not present but is
1330 requested.
1331
Georg Brandlddbaa662006-06-04 21:56:52 +00001332- Patch #1346214: Statements like "if 0: suite" are now again optimized
1333 away like they were in Python 2.4.
1334
Georg Brandlb7c8f542006-05-27 12:30:25 +00001335- Builtin exceptions are now full-blown new-style classes instead of
1336 instances pretending to be classes, which speeds up exception handling
1337 by about 80% in comparison to 2.5a2.
1338
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001339- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1340 Unicode 4.1.
1341
Georg Brandlf4ef1162006-05-26 18:03:31 +00001342- Patch #921466: sys.path_importer_cache is now used to cache valid and
1343 invalid file paths for the built-in import machinery which leads to
1344 fewer open calls on startup.
1345
Tim Peters696cf432006-05-24 21:10:40 +00001346- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1347 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1348 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1349 the number of input digits (it was and remains linear-time for bases
1350 2, 4, 8, 16 and 32).
1351
Tim Petersb713ec22006-05-23 18:45:30 +00001352- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1353 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1354 an integer close to ``sys.maxint``. This was repaired by patch
1355 #1335972, which also gives a nice speedup.
1356
Richard Jonescebbefc2006-05-23 18:28:17 +00001357- Patch #1337051: reduced size of frame objects.
1358
1359- PyErr_NewException now accepts a tuple of base classes as its
1360 "base" parameter.
1361
Richard Jones7c88dcc2006-05-23 10:37:38 +00001362- Patch #876206: function call speedup by retaining allocated frame
1363 objects.
1364
Georg Brandl7b90e162006-05-18 07:01:27 +00001365- Bug #1462152: file() now checks more thoroughly for invalid mode
1366 strings and removes a possible "U" before passing the mode to the
1367 C library function.
1368
Neal Norwitz1004a532006-05-15 07:17:23 +00001369- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1370
Neal Norwitz373f0a72006-05-15 07:04:36 +00001371- Bug #1487966: Fix SystemError with conditional expression in assignment
1372
Martin v. Löwis879768d2006-05-11 13:28:43 +00001373- WindowsError now has two error code attributes: errno, which carries
1374 the error values from errno.h, and winerror, which carries the error
1375 values from winerror.h. Previous versions put the winerror.h values
1376 (from GetLastError()) into the errno attribute.
1377
Martin v. Löwis77736712006-05-04 05:51:03 +00001378- Patch #1475845: Raise IndentationError for unexpected indent.
1379
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001380- Patch #1479181: split open() and file() from being aliases for each other.
1381
Tim Peters44bd9862006-06-01 13:49:23 +00001382- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1383 methods were always silently ignored by dictionaries when comparing keys.
1384 They are now passed through (except when using the C API function
1385 ``PyDict_GetItem()``, whose semantics did not change).
1386
1387- Bug #1456209: In some obscure cases it was possible for a class with a
1388 custom ``__eq__()`` method to confuse dict internals when class instances
1389 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1390 No, you don't have any code that did this ;-)

1403
Nick Coghlanc649ec52006-05-29 12:43:05 +00001404- Patch #1478788 (modified version): The functional extension module has
1405 been renamed to _functools and a functools Python wrapper module added.
1406 This provides a home for additional function related utilities that are
1407 not specifically about functional programming. See PEP 309.
1408
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001409- Patch #1493701: performance enhancements for struct module.

1417 enabled builds on Windows and systems with Posix threads support.
1418
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001419- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1420 (up to the system limit of 32K characters).
1421
1422- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1423 As a result, these functions now raise WindowsError instead of OSError.
1424
Tim Peters7a822da2006-05-25 21:50:17 +00001425- ``time.clock()`` on Win64 should use the high-performance Windows
1426 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1427 Windows platforms).
1428
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001429- Calling Tk_Init twice is refused if the first call failed as that
1430 may deadlock.
1431
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001432- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1433 accept it without potentially using an uninitialized pointer.
1434
1435- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1436 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

1446 results. It could previously incorrectly return 0 in some cases.
1447 Fixes SF bug 1493322 (pybsddb bug 1184012).
1448
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001449- bsddb: the bsddb.dbtables Modify method now raises the proper error and

1451 Fixes SF python patch/bug #1408584.
1452
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001453- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001454 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001455 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1456 database calls that would previously deadlock. [SF python bug #775414]

1475
Martin v. Löwis337487e2006-06-17 09:15:14 +00001476- Patch #763580: Add name and value arguments to Tkinter variable
1477 classes.
1478
Georg Brandl83cc0d02006-06-14 08:50:03 +00001479- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1480 mime.types file for determining MIME types.
1481
Georg Brandl2605ca82006-06-14 06:08:31 +00001482- Bug #1339007: Shelf objects now don't raise an exception in their
1483 __del__ method when initialization failed.
1484
Martin v. Löwisd8251432006-06-14 05:21:04 +00001485- Patch #1455898: The MBCS codec now supports the incremental mode for
1486 double-byte encodings.
1487
Tim Peters43898b42006-06-14 04:09:25 +00001488- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1489 guarantee that adjacent triples in the return list always describe
1490 non-adjacent blocks. Previously, a pair of matching blocks could end
1491 up being described by multiple adjacent triples that formed a partition
1492 of the matching pair.
1493
Greg Ward0e0c9f42006-06-11 16:24:11 +00001494- Bug #1498146: fix optparse to handle Unicode strings in option help,
1495 description, and epilog.
1496
Greg Wardd1c797e2006-06-11 14:42:41 +00001497- Bug #1366250: minor optparse documentation error.
1498
Greg Ward7f547402006-06-11 00:40:49 +00001499- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1500 clarify docs.
1501
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001502- The wsgiref package has been added to the standard library.
1503
Nick Coghlan676725d2006-06-08 13:54:49 +00001504- The functions update_wrapper() and wraps() have been added to the functools
1505 module. These make it easier to copy relevant metadata from the original
1506 function when writing wrapper functions.
1507
Tim Petersd6a9eef2006-06-05 01:48:21 +00001508- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1509 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001510
Martin v. Löwis3f767792006-06-04 19:36:28 +00001511- Patch #1359618: Speed up charmap encoder by using a trie structure
1512 for lookup.
1513
Tim Petersd609b1a2006-06-02 23:22:51 +00001514- The functions in the ``pprint`` module now sort dictionaries by key
1515 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1516 if and only if its display required more than one line, although that
1517 wasn't documented. The new behavior increases predictability; e.g.,
1518 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1519
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001520- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1521 (thanks for J. J. Lee).
1522
Georg Brandl2b330372006-05-28 20:23:12 +00001523- Patch #1496206: improve urllib2 handling of passwords with respect to
1524 default HTTP and HTTPS ports.
1525
George Yoshidaf3c65de2006-05-28 16:39:09 +00001526- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1527
Bob Ippolito7298f272006-05-23 18:43:47 +00001528- Patch #1281707: speed up gzip.readline.
1529
Georg Brandlb89316f2006-05-17 15:51:16 +00001530- Patch #1180296: Two new functions were added to the locale module:
1531 format_string() to get the effect of "format % items" but locale-aware,
1532 and currency() to format a monetary number with currency sign.
1533
Georg Brandle3a25832006-05-17 14:56:04 +00001534- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1535 and several features added, such as speed and geometry control.
1536
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001537- Patch #1488881: add support for external file objects in bz2 compressed
1538 tarfiles.
1539
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001540- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1541 stdout arguments, making it possible to redirect input and output
1542 for remote debugging.
1543
1544- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1545 a couple of issues, notably handling of long file names using the
1546 GNU LONGNAME extension.
1547
1548- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1549 new flag when ``name`` is already the name of an option flag.
1550
1551- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1552 package.
1553
1554- Patch #1472854: make the rlcompleter.Completer class usable on non-
1555 UNIX platforms.
1556
1557- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1558
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001559- Bug #1472827: correctly escape newlines and tabs in attribute values in
1560 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001590What's New in Python 2.5 alpha 2?

1592
1593*Release date: 27-APR-2006*
1594
1595Core and builtins
1596-----------------
1597
Thomas Heller1b046642006-04-18 18:51:06 +00001598- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1599 by converting these apis from macros into exported functions again:
1600
1601 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1602 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1603 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1604 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1605 PyRun_String Py_CompileString
1606
Martin v. Löwis45294a92006-04-18 06:24:08 +00001607- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1608
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001609- All uses of PyStructSequence_InitType have been changed to initialize
1610 the type objects only once, even if the interpreter is initialized
1611 multiple times.
1612
Neal Norwitz61546162006-04-14 05:20:28 +00001613- Bug #1454485, array.array('u') could crash the interpreter. This was
1614 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1615 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1616
1617- Py_UNICODE is unsigned. It was always documented as unsigned, but
1618 due to a bug had a signed value in previous versions.
1619
Tim Peters3a5e8b12006-04-11 01:44:07 +00001620- Patch #837242: ``id()`` of any Python object always gives a positive
1621 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1622 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001623 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001624 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001625
Tim Peters3a5e8b12006-04-11 01:44:07 +00001626 def __hash__(self):
1627 return id(self) # WRONG
1628
1629 because a hash result must be a (short) Python int but it was always
1630 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001631 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001632 was always usable as a hash value before this patch. That's no longer
1633 necessarily so.
1634
1635- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001636 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001637 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001638 #1454844)
1639
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001640- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1641 involving generators that have paused outside of any ``try`` or ``with``
1642 blocks. (In 2.5a1, a paused generator that was part of a reference
1643 cycle could not be garbage collected, regardless of whether it was
1644 paused in a ``try`` or ``with`` block.)

1651
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001652- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1653 fails with an error condition.
1654
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001655- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.

1657- Bug #1117761: bsddb.*open() no longer raises an exception when using
1658 the cachesize parameter.
1659
1660- Bug #1149413: bsddb.*open() no longer raises an exception when using
1661 a temporary db (file=None) with the 'n' flag to truncate on open.
1662
1663- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1664 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001665
Armin Rigoa9017c32006-04-19 11:50:27 +00001666- Patch #1062014: AF_UNIX sockets under Linux have a special
1667 abstract namespace that is now fully supported.

Peter Astrand7d1d4362006-07-14 14:04:45 +00001672- Bug #1223937: subprocess.CalledProcessError reports the exit status
1673 of the process using the returncode attribute, instead of
1674 abusing errno.
1675
Tim Peters711bf302006-04-25 03:31:36 +00001676- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1677 a doctest to be skipped (the code is not run, and the expected output
1678 or exception is ignored).
1679
Nick Coghlanda2268f2006-04-24 04:37:15 +00001680- Fixed contextlib.nested to cope with exceptions being raised and
1681 caught inside exit handlers.
1682
Greg Wardab05edc2006-04-23 03:47:58 +00001683- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1684 hex, octal, or binary; add ``append_const`` action; keep going if
1685 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1686 added ``epilog`` for better help generation).
1687
Tim Peters21fbd572006-04-21 21:18:10 +00001688- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1689 called from a thread spawned as a side effect of importing a module.
1690
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001691- The pydoc module now supports documenting packages contained in
1692 .zip or .egg files.
1693
1694- The pkgutil module now has several new utility functions, such
1695 as ``walk_packages()`` to support working with packages that are either
1696 in the filesystem or zip files.
1697
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001698- The mailbox module can now modify and delete messages from
1699 mailboxes, in addition to simply reading them. Thanks to Gregory
1700 K. Johnson for writing the code, and to the 2005 Google Summer of
1701 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001702
Tim Petersc7605f22006-04-17 21:12:33 +00001703- The ``__del__`` method of class ``local`` in module ``_threading_local``
1704 returned before accomplishing any of its intended cleanup.
1705
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001706- Patch #790710: Add breakpoint command lists in pdb.

1711
Anthony Baxtere29002c2006-04-12 12:07:31 +00001712- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1713 Windows. Bug #1469163.
1714
Phillip J. Eby47032112006-04-11 01:07:43 +00001715- The warnings, linecache, inspect, traceback, site, and doctest modules
1716 were updated to work correctly with modules imported from zipfiles or
1717 via other PEP 302 __loader__ objects.
1718
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001719- Patch #1467770: Reduce usage of subprocess._active to processes which

1731
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001732- The Makefile now has a reindent target, which runs reindent.py on
1733 the library.
1734
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001735- Patch #1470875: Building Python with MS Free Compiler

1740 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001741 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001742 CXX from --with-cxx-main, see description in README.
1743

1747
Tim Peters8931ff12006-05-13 23:28:20 +00001748- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1749 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1750 and "%zu" for unsigned integers of type ``size_t``.
1751
Anthony Baxter51bcb682006-04-05 14:51:42 +00001752Tests
1753-----
1754
Nick Coghlanda2268f2006-04-24 04:37:15 +00001755- test_contextlib now checks contextlib.nested can cope with exceptions
1756 being raised and caught inside exit handlers.
1757
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001758- test_cmd_line now checks operation of the -m and -c command switches
1759
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001760- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1761 it separately and by hand. It also wasn't cleaning up its changes to
1762 the current Decimal context.
1763
Thomas Woutersabd08882006-04-26 15:53:30 +00001764- regrtest.py now has a -M option to run tests that test the new limits of
1765 containers, on 64-bit architectures. Running these tests is only sensible
1766 on 64-bit machines with more than two gigabytes of memory. The argument
1767 passed is the maximum amount of memory for the tests to use.

1776-------------
1777
Tim Petersb06d28c2006-05-12 01:57:59 +00001778- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1779
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001780- PEP 343: Added Context Types section to the library reference
1781 and attempted to bring other PEP 343 related documentation into
1782 line with the implementation and/or python-dev discussions.
1783
Tim Peters8dc73d22006-04-24 02:03:16 +00001784- Bug #1337990: clarified that ``doctest`` does not support examples
1785 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001788What's New in Python 2.5 alpha 1?
1789=================================
1790
Anthony Baxterebed3f62006-04-03 15:03:44 +00001791*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001792
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001793Core and builtins
1794-----------------
1795
Nick Coghlan43832302006-04-23 17:04:07 +00001796- PEP 338: -m command line switch now delegates to runpy.run_module
1797 allowing it to support modules in packages and zipfiles
1798
Martin v. Löwisc661b882006-04-20 04:54:23 +00001799- On Windows, .DLL is not an accepted file name extension for
1800 extension modules anymore; extensions are only found if they
1801 end in .PYD.
1802
Martin v. Löwisea62d252006-04-03 10:56:49 +00001803- Bug #1421664: sys.stderr.encoding is now set to the same value as
1804 sys.stdout.encoding.
1805
Neal Norwitz92e212f2006-04-03 04:48:37 +00001806- __import__ accepts keyword arguments.
1807
Georg Brandlccadf842006-03-31 18:54:53 +00001808- Patch #1460496: round() now accepts keyword arguments.
1809
Anthony Baxter262c00a2006-03-30 10:53:17 +00001810- Fixed bug #1459029 - unicode reprs were double-escaped.
1811
Hye-Shik Changd478f342006-03-23 12:32:36 +00001812- Patch #1396919: The system scope threads are reenabled on FreeBSD
1813 5.4 and later versions.
1814
Neal Norwitze98ccf62006-03-23 05:39:47 +00001815- Bug #1115379: Compiling a Unicode string with an encoding declaration
1816 now gives a SyntaxError.
1817
Georg Brandlabd1ff82006-03-18 07:59:59 +00001818- Previously, Python code had no easy way to access the contents of a
1819 cell object. Now, a ``cell_contents`` attribute has been added
1820 (closes patch #1170323).
1821
Tim Peterscf79aac2006-03-16 01:14:46 +00001822- Patch #1123430: Python's small-object allocator now returns an arena to
1823 the system ``free()`` when all memory within an arena becomes unused
1824 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1825 freed. Some applications will see a drop in virtual memory size now,
1826 especially long-running applications that, from time to time, temporarily
1827 use a large number of small objects. Note that when Python returns an
1828 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001829 platform C library will in turn return that memory to the operating system.
1830 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001831 appears to be effective at least on Microsoft C and gcc-based systems.
1832 Thanks to Evan Jones for hard work and patience.
1833
Georg Brandl533ff6f2006-03-08 18:09:27 +00001834- Patch #1434038: property() now uses the getter's docstring if there is
1835 no "doc" argument given. This makes it possible to legitimately use
1836 property() as a decorator to produce a read-only property.
1837
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001838- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1839 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1840 of requiring an int or long in slicing and a few other contexts, enabling
1841 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1842
Neal Norwitz995acdf2006-03-07 05:01:00 +00001843- Fixed various bugs reported by Coverity's Prevent tool.
1844
Brett Cannonbf364092006-03-01 04:25:17 +00001845- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1846 new exception base class, BaseException, which has a new message attribute.
1847 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1848 Raising a string exception now raises a DeprecationWarning.
1849
Thomas Woutersfb609f42006-02-28 16:37:25 +00001850- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1851 explicitly relative, using 'from .module import name' to mean 'from the same
1852 package as this module is in. Imports without dots still default to the
1853 old relative-then-absolute, unless 'from __future__ import
1854 absolute_import' is used.
1855
Brett Cannona7446e32006-02-27 23:39:10 +00001856- Properly check if 'warnings' raises an exception (usually when a filter set
1857 to "error" is triggered) when raising a warning for raising string
1858 exceptions.
1859
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001860- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001861 The name was removed from Include/code.h.
1862
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001863- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001864
Guido van Rossum1968ad32006-02-25 22:38:04 +00001865- Patch 1433928:
1866 - The copy module now "copies" function objects (as atomic objects).
1867 - dict.__getitem__ now looks for a __missing__ hook before raising
1868 KeyError.
1869
Tim Peters84ef21c2006-02-28 20:39:06 +00001870- PEP 343: with statement implemented. Needs ``from __future__ import
1871 with_statement``. Use of 'with' as a variable will generate a warning.
1872 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001873 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001874 The following objects have __context__ methods:
1875 - The built-in file type.
1876 - The thread.LockType type.
1877 - The following types defined by the threading module:
1878 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1879 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001880
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001881- Fix the encodings package codec search function to only search
1882 inside its own package. Fixes problem reported in patch #1433198.
1883
1884 Note: Codec packages should implement and register their own
1885 codec search function. PEP 100 has the details.
1886
Tim Peters9ea89d22006-06-04 03:26:02 +00001887- PEP 353: Using ``Py_ssize_t`` as the index type.
1888
1889- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1890 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1891 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1892 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1893 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001894
Neal Norwitzfc76d632006-01-10 06:03:13 +00001895- Patch #1400181, fix unicode string formatting to not use the locale.
1896 This is how string objects work. u'%f' could use , instead of .
1897 for the decimal point. Now both strings and unicode always use periods.
1898
Neal Norwitz671b9e32006-01-09 07:07:12 +00001899- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1900 configure would break checking curses.h.
1901
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001902- Bug #959576: The pwd module is now builtin. This allows Python to be
1903 built on UNIX platforms without $HOME set.
1904
Neal Norwitzc10978f2005-12-19 06:07:16 +00001905- Bug #1072182, fix some potential problems if characters are signed.
1906
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001907- Bug #889500, fix line number on SyntaxWarning for global declarations.
1908
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001909- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1910
Neal Norwitze7214a12005-12-18 05:03:17 +00001911- Support for converting hex strings to floats no longer works.
1912 This was not portable. float('0x3') now raises a ValueError.
1913
Barry Warsaw2a38a862005-12-18 01:27:35 +00001914- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001915 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001916 is now displayed in interactive prompt banner.
1917
Georg Brandlfa166682005-12-17 21:45:17 +00001918- Implementation of PEP 341 - Unification of try/except and try/finally.
1919 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001920 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001921
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001922- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1923 now encodes backslash correctly.
1924
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001925- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1926
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001927- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001928 and long longs.
1929
Neal Norwitz67715f02005-11-09 06:59:35 +00001930- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001931 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001932 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001933
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001934- Replaced most Unicode charmap codecs with new ones using the
1935 new Unicode translate string feature in the builtin charmap
1936 codec; the codecs were created from the mapping tables available
1937 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1938 encodings now include a mapping for the Apple logo)
1939
Tim Peterse3547fd2005-12-16 23:13:57 +00001940- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001941
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001942- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001943
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001944- A new AST parser implementation was completed. The abstract
1945 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001946 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001947
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001948- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001949 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1950
Neal Norwitz708e51a2005-10-03 04:48:15 +00001951- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1952
Neal Norwitz11bd1192005-10-03 00:54:56 +00001953- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1954 Provide a warning when a directory is passed on the command line.
1955
Neal Norwitz40d37812005-10-02 01:48:49 +00001956- Fix segfault with invalid coding.
1957
1958- SF bug #772896: unknown encoding results in MemoryError.
1959
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001960- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001961 supported a __len__() method which evaluated to False when the iterator
1962 was empty.
1963
Guido van Rossum630db602005-09-20 18:49:54 +00001964- On 64-bit platforms, when __len__() returns a value that cannot be
1965 represented as a C int, raise OverflowError.
1966
Skip Montanarof8948ca2005-09-19 03:54:46 +00001967- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001968 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001969
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001970- SF bug #893549: parsing keyword arguments was broken with a few format
1971 codes.
1972
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001973- Changes donated by Elemental Security to make it work on AIX 5.3
1974 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1975 bug #105470: test_pwd fails on 64bit system (Opteron).
1976
Guido van Rossum539c6622005-09-14 17:49:54 +00001977- Changes donated by Elemental Security to make it work on HP-UX 11 on
1978 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1979
Georg Brandl4550b8d2005-08-26 06:43:52 +00001980- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001981 (fixes bug #1119418).
1982
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001983- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1984
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001985- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1986 exceptions that cause a function to exit.
1987
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001988- The implementation of set() and frozenset() was revised to use its
1989 own internal data structure. Memory consumption is reduced by 1/3
1990 and there are modest speed-ups as well. The API is unchanged.
1991
Tim Petersde7990b2005-07-17 23:45:23 +00001992- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1993
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001994- SF bug #1229429: PyObject_CallMethod failed to decrement some
1995 reference counts in some error exit cases.
1996
Tim Petersecc6e6a2005-07-10 22:30:55 +00001997- SF bug #1185883: Python's small-object memory allocator took over
1998 a block managed by the platform C library whenever a realloc specified
1999 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002000 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002001 portable way to copy data from the C-managed block into Python's
2002 small-object space without risking a memory fault. Python's small-object
2003 realloc now leaves such blocks under the control of the platform C
2004 realloc.
2005
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002006- SF bug #1232517: An overflow error was not detected properly when
2007 attempting to convert a large float to an int in os.utime().
2008
Raymond Hettinger3296e692005-06-29 23:29:56 +00002009- SF bug #1224347: hex longs now print with lowercase letters just
2010 like their int counterparts.
2011
Michael W. Hudson188d4362005-06-20 16:52:57 +00002012- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2013 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2014 interpreter states; back out that fix and do a better job (see
2015 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2016 for a longer write-up of the problem).
2017
Michael W. Hudsondf888462005-06-03 14:41:55 +00002018- SF patch #1180995: marshal now uses a binary format by default when
2019 serializing floats.
2020
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002021- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2022 the routines that promise to produce IEEE 754 binary representations
2023 of floats now simply copy bytes around.
2024
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002025- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2026 278.
2027
Brett Cannonc3647ac2005-04-26 03:45:26 +00002028- patch #1109424: int, long, float, complex, and unicode now check for the
2029 proper magic slot for type conversions when subclassed. Previously the
2030 magic slot was ignored during conversion. Semantics now match the way
2031 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002032 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002033 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002034 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002035
Barry Warsawc8d907c2005-04-19 23:43:40 +00002036- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2037 NULL, now raise an AttributeError when attempting to set or delete the
2038 attribute. Previously a TypeError was raised, but this was inconsistent
2039 with the equivalent pure-Python implementation.
2040
Michael W. Hudson774479c2005-04-18 08:46:17 +00002041- It is now safe to call PyGILState_Release() before
2042 PyEval_InitThreads() (note that if there is reason to believe there
2043 are multiple threads around you still must call PyEval_InitThreads()
2044 before using the Python API; this fix is for extension modules that
2045 have no way of knowing if Python is multi-threaded yet).
2046
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002047- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2048 disabled caused a crash.
2049
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002050- Bug #1165306: instancemethod_new allowed the creation of a method

2100 it (since the thread state is being deleted, continuing to remember it
2101 can't help, but can hurt if another thread happens to get created with
2102 the same thread id).

Tim Petersc17976e2006-04-01 00:26:53 +00002317- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2318 aren't officially supported here, and trying to use them will probably
2319 raise an exception some day. But dicts have been allowed, and "mostly
2320 worked", so support for them won't go away without warning.
2321
Georg Brandl338ef7d2006-03-31 18:42:16 +00002322- Bug #1445068: getpass.getpass() can now be given an explicit stream
2323 argument to specify where to write the prompt.
2324
Georg Brandl22ec80b2006-03-31 18:25:44 +00002325- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2332
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002333- Queue.Queue objects now support .task_done() and .join() methods
2334 to make it easier to monitor when daemon threads have completed
2335 processing all enqueued tasks. Patch #1455676.
2336
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002337- popen2.Popen objects now preserve the command in a .cmd attribute.

2340
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002341- email 4.0 package now integrated. This is largely the same as the email 3.0
2342 package that was included in Python 2.3, except that PEP 8 module names are
2343 now used (e.g. mail.message instead of email.Message). The MIME classes
2344 have been moved to a subpackage (e.g. email.mime.text instead of
2345 email.MIMEText). The old names are still supported for now. Several
2346 deprecated Message methods have been removed and lots of bugs have been
2347 fixed. More details can be found in the email package documentation.
2348
Walter Dörwald40108c92006-03-27 08:15:44 +00002349- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2350 (a subclass of tuple) that provides incremental decoders and encoders
2351 (a way to use stateful codecs without the stream API). Python functions
2352 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2353 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2354 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002355
Walter Dörwald067db482006-03-15 22:17:27 +00002356- Patch #1359365: Calling next() on a closed StringIO.String object raises
2357 a ValueError instead of a StopIteration now (like file and cString.String do).
2358 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2359 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002360
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002361- A regrtest option -w was added to re-run failed tests in verbose mode.

2367 grew an optional 'generation' argument.
2368
Martin v. Löwisfbab90e2006-03-05 13:36:04 +00002369- A library msilib to generate Windows Installer files, and a distutils

2429 LoadError as documented, instead of IOError. For compatibility,
2430 LoadError subclasses IOError.
2431

Tim Peterse3547fd2005-12-16 23:13:57 +00002433 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2434 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2435 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2436 Ronald L. Rivest offered this advice for Python:
2437
2438 "The consensus of researchers in this area (at least as
2439 expressed at the NIST Hash Function Workshop 10/31/05),
2440 is that SHA-256 is a good choice for the time being, but
2441 that research should continue, and other alternatives may
2442 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002443
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002444- Added a subset of Fredrik Lundh's ElementTree package. Available

2594
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00002595- Patch #1104111: Alter setup.py --help and --help-commands.
2596
Martin v. Löwis4afe1542005-03-01 08:09:28 +00002597- Patch #1121234: Properly cleanup _exit and tkerror commands.
2598
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00002599- Patch #1049151: xdrlib now unpacks booleans as True or False.
2600
Raymond Hettingerbab41432005-02-05 01:31:19 +00002601- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2602
Guido van Rossumd0641422005-02-03 15:01:24 +00002603- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2604 disables recursive traversal through instance attributes, which can
2605 be exploited in various ways.
2606
Tim Peterse3547fd2005-12-16 23:13:57 +00002607- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002608 flags on the HTTP listening socket.
2609
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002610- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2611 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2612
Fred Drakefbdeaad2006-07-29 16:56:15 +00002613- Patches #893642, #1039083: add allow_none, encoding arguments to
2614 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002615

Thomas Hellerd6c6e222005-01-20 19:20:16 +00002618- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2619
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002620- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2621
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002622- Enhancements to the csv module:
2623
2624 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002625 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002626 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002627 + Dialect parameter parsing has been re-implemented to improve error
2628 reporting.
2629 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2630 dictates.
2631 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002632 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002633 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002634 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2635 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002636 + reader now allows \r characters to be quoted (previously it only allowed
2637 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002638 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002639 + Dialect classes passed to the module are no longer instantiated by
2640 the module before being parsed (the former validation scheme required
2641 this, but the mechanism was unreliable).
2642 + The dialect registry now contains instances of the internal
2643 C-coded dialect type, rather than references to python objects.
2644 + the internal c-coded dialect type is now immutable.
2645 + register_dialect now accepts the same keyword dialect specifications
2646 as the reader and writer, allowing the user to register dialects
2647 without first creating a dialect class.
2648 + a configurable limit to the size of parsed fields has been added -
2649 previously, an unmatched quote character could result in the entire
2650 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002651 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002652 the parser field size limit (returning the former limit). The initial
2653 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002654 + A line_num attribute has been added to the reader object, which tracks
2655 the number of lines read from the source iterator. This is not
2656 the same as the number of records returned, as records can span
2657 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002658 + reader and writer objects were not being registered with the cyclic-GC.
2659 This has been fixed.
2660
Brett Cannone6539c42005-01-08 02:43:53 +00002661- _DummyThread objects in the threading module now delete self.__block that is
2662 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2663 lock primitives tend to be limited in number and thus should not be wasted on
2664 a _DummyThread object. Fixes bug #1089632.
2665
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002666- The imghdr module now detects Exif files.
2667
Raymond Hettinger6065d322004-12-20 23:51:53 +00002668- StringIO.truncate() now correctly adjusts the size attribute.
2669 (Bug #951915).
2670
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002671- locale.py now uses an updated locale alias table (built using
2672 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2673 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002674 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002675
Raymond Hettinger3557f422004-12-07 12:02:02 +00002676- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2677
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002678- the pickle module no longer accepts the deprecated None option in the
2679 args tuple returned by __reduce__().
2680
Brett Cannon84667c02004-12-07 03:25:18 +00002681- optparse now optionally imports gettext. This allows its use in setup.py.
2682
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002683- the pickle module no longer uses the deprecated bin parameter.
2684
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002685- the shelve module no longer uses the deprecated binary parameter.
2686
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002687- the pstats module no longer uses the deprecated ignore() method.
2688
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002689- the filecmp module no longer uses the deprecated use_statcache argument.
2690
Raymond Hettinger664347b2004-12-04 21:21:53 +00002691- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2692 extended or overridden by subclasses. Formerly, the subclassed method would
2693 be ignored by the rest of the module. (Bug #1078905).
2694
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002695- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002696 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002697
Walter Dörwald36733692004-12-22 12:50:50 +00002698- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2699 once when a size argument is given. This prevents a buffer overflow in the
2700 tokenizer with very long source lines.
2701
Barry Warsaw538561e2006-01-01 21:48:54 +00002702- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2703 immediately after creating the object, without any intervening
2704 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002705
Skip Montanaro05885812005-01-16 20:48:27 +00002706- The reconvert.quote function can now emit triple-quoted strings. The
2707 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002708
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002709- ``UserString.MutableString`` now supports negative indices in
2710 ``__setitem__`` and ``__delitem__``
2711
Greg Ward40407942005-03-05 02:53:17 +00002712- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2713 correctly.
2714
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002715- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2716 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2717 character even if the user has passed a size parameter to get a proper
2718 line ending. Remove the special handling of a "\r\n" that has been split
2719 between two lines.
2720
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002721- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2722 about illegal code points. The codec now supports PEP 293 style error
2723 handlers.
2724
Walter Dörwald78a78b02005-09-01 12:04:29 +00002725- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002726 from the input stream, so that the output is a byte string in the correct
2727 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002728
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002729- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2730 considering it exactly like a '*'.
2731
Walter Dörwald007f8df2005-10-09 19:42:27 +00002732- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2733 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002734
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002735- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2736
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002737- Patch #1413711: Certain patterns of differences were making difflib
2738 touch the recursion limit.
2739
Walter Dörwald58917a62006-03-31 15:26:22 +00002740- Bug #947906: An object oriented interface has been added to the calendar
2741 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002742 called as a script (e.g. via ``python -mcalendar``). Localized month and
2743 weekday names can be ouput (even if an exotic encoding is used) using
2744 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002745
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002746Build
2747-----
2748
Neal Norwitz602d3392006-03-31 08:21:40 +00002749- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2750 by using -mieee gcc option.
2751
Martin v. Löwis86d66262006-02-17 08:40:11 +00002752- Patch #1432345: Make python compile on DragonFly.
2753
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002754- Build support for Win64-AMD64 was added.
2755
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002756- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2757
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002758- Patch #881820: look for openpty and forkpty also in libbsd.
2759
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002760- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2761 The zlib module is now builtin on Windows.
2762
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002763- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2764
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002765- Bug #1189330: configure did not correctly determine the necessary
2766 value of LINKCC if python was built with GCC 4.0.
2767
Trent Mick8321b422005-07-26 02:29:21 +00002768- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2769 vulnerability in zlib 1.2.1 and 1.2.2.
2770
Brett Cannon08cd5982005-04-24 22:26:38 +00002771- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2772 flags that change binary compatibility. Changes were also made to
2773 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002774 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002775
Bob Ippolitoed233462005-03-29 13:47:59 +00002776- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2777 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2778 no longer exists). This configure patch makes things right.
2779
Martin v. Löwise2713be2005-03-08 15:03:08 +00002780- Bug #1158607: Build with --disable-unicode again.
2781
Brett Cannon46d96232005-02-16 00:07:19 +00002782- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2783 defined. Discovered as a result of not being able to build on OS X.
2784
Brett Cannon516592f2004-12-07 00:42:59 +00002785- setup.py now uses the directories specified in LDFLAGS using the -L option
2786 and in CPPFLAGS using the -I option for adding library and include
2787 directories, respectively, for compiling extension modules against. This has
2788 led to the core being compiled using the values in CPPFLAGS. It also removes
2789 the need for the special-casing of both DarwinPorts and Fink for darwin since
2790 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2791 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2792 Fink, ``-I/opt/local/include`` for DarwinPorts).
2793
Brett Cannon43802422005-02-10 20:48:03 +00002794- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2795 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2796 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2797 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002799C API
2800-----
2801
Tim Petersc9d78aa2006-03-26 23:27:58 +00002802- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2803 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2804 is obtained via the ``PyObject_`` family, it must be released via the
2805 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2806 always been officially true, but when Python's small-object allocator was
2807 introduced, an attempt was made to cater to a few extension modules
2808 discovered at the time that obtained memory via ``PyObject_New`` but
2809 released it via ``PyMem_DEL``. It's years later, and if such code still
2810 exists it will fail now (probably with segfaults, but calling wrong
2811 low-level memory management functions can yield many symptoms).
2812
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002813- Added a C API for set and frozenset objects.
2814
Raymond Hettinger66517482004-12-03 11:45:13 +00002815- Removed PyRange_New().
2816
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002817- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2818 mapping argument now. This string is used as a mapping table. Byte values
2819 greater than the length of the string and 0xFFFE are treated as undefined
2820 mappings.
