594 outside of pystate.c and should not be necessary.
595
Brett Cannon19d76c52006-09-09 07:18:44 +0000596- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
597 allows calling unicode() on exceptions classes directly to succeed.
598
Georg Brandlecab6232006-09-06 06:47:02 +0000599- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000614- The return tuple from str.rpartition(sep) is (tail, sep, head) where
615 head is the original string if sep was not found.
616
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000617- Bug #1520864: unpacking singleton tuples in list comprehensions and
618 generator expressions (x for x, in ... ) works again. Fixing this problem
619 required changing the .pyc magic number. This means that .pyc files
620 generated before 2.5c2 will be regenerated.

732Core and builtins
733-----------------
734
Neal Norwitz24b6f202006-09-05 04:43:56 +0000735- Fix infinite recursion when subclassing long and overriding __hash__.
736
737- Fix concatenation (+=) of long strings.
738
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000739- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000740 compared equal or unequal to a string and a UnicodeDecodeError
741 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000742
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000743 Instead, the equal (==) and unequal (!=) comparison operators will
744 now issue a UnicodeWarning and interpret the two objects as
745 unequal. The UnicodeWarning can be filtered as desired using
746 the warning framework, e.g. silenced completely, turned into an
747 exception, logged, etc.
748
749 Note that compare operators other than equal and unequal will still
750 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000751
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000752- Fix segfault when doing string formatting on subclasses of long.
753
754- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
755 with new-style classes.
756
757- Fix bug related to __len__ functions returning negative values with
758 classic classes.
759
760- Patch #1538606, Fix __index__() clipping. There were some problems
761 discovered with the API and how integers that didn't fit into Py_ssize_t
762 were handled. This patch attempts to provide enough alternatives
763 to effectively use __index__.
764
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000765- Bug #1536021: __hash__ may now return long int; the final hash
766 value is obtained by invoking hash on the long int.
767
Thomas Hellerab1049c2006-08-08 17:37:00 +0000768- Bug #1536786: buffer comparison could emit a RuntimeWarning.
769
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000770- Bug #1535165: fixed a segfault in input() and raw_input() when
771 sys.stdin is closed.
772
Thomas Heller74d36f02006-08-04 18:17:40 +0000773- On Windows, the PyErr_Warn function is now exported from
774 the Python dll again.
775
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000776- Bug #1191458: tracing over for loops now produces a line event
777 on each iteration. Fixing this problem required changing the .pyc
778 magic number. This means that .pyc files generated before 2.5c1
779 will be regenerated.
780
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000781- Bug #1333982: string/number constants were inappropriately stored
782 in the byte code and co_consts even if they were not used, ie
783 immediately popped off the stack.
784
Georg Brandle9462c72006-08-04 18:03:37 +0000785- Fixed a reference-counting problem in property().

788Library
789-------
790
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000791- Fix a bug in the ``compiler`` package that caused invalid code to be
792 generated for generator expressions.
793
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000794- The distutils version has been changed to 2.5.0. The change to
795 keep it programmatically in sync with the Python version running
796 the code (introduced in 2.5b3) has been reverted. It will continue
797 to be maintained manually as static string literal.
798
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000799- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000800 and this cannot be converted to the required C type, an exception is
801 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000802 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000803
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000804- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000805 an exception.
806
Tim Peterscbdd3502006-09-05 01:47:53 +0000807- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000808 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000809 workarounds for clocks with low resolution, to stop the code yielding
810 duplicate UUIDs.
811
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000812- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
813 before raising SystemExit, allowing IDLE to honor quit() and exit().
814
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000815- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
816
Georg Brandl7a1af772006-08-14 21:55:28 +0000817- Patch #1536071: trace.py should now find the full module name of a
818 file correctly even on Windows.
819
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000820- logging's atexit hook now runs even if the rest of the module has
821 already been cleaned up.
822
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000823- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000824
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000825- Bug #1531405, format_exception no longer raises an exception if
826 str(exception) raised an exception.
827
Neil Schemenauer06ded092006-08-04 16:20:30 +0000828- Fix a bug in the ``compiler`` package that caused invalid code to be
829 generated for nested functions.

847 function calls. The ctypes version number was changed to 1.0.1.
848
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000849- Bug #1530559, struct.pack raises TypeError where it used to convert.
850 Passing float arguments to struct.pack when integers are expected
851 now triggers a DeprecationWarning.

Neal Norwitza1f10902006-07-12 07:28:29 +0000900
901Core and builtins
902-----------------
903
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000904- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000905 returned a long (see PEP 353).
906
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000907- Bug #1515471: string.replace() accepts character buffers again.
908
Neal Norwitz07aadb12006-07-30 06:55:48 +0000909- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
910 This provides the proper warning for struct.pack().
911 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
912
Neal Norwitz0d62a062006-07-30 06:53:31 +0000913- Patch #1531113: Fix augmented assignment with yield expressions.
914 Also fix a SystemError when trying to assign to yield expressions.
915
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000916- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
917 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
918 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
919 excessive filesystem operations during imports.
920
Tim Petersbc24eee2006-07-27 01:14:53 +0000921- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
922 operations on signed longs that are formally undefined by C.
923 Unfortunately, at least one compiler now cares about that, so complicated
924 the code to make that compiler happy again.
925
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000926- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
927
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000928- Patch #1232023: Stop including current directory in search
929 path on Windows.
930
Neal Norwitze1fdb322006-07-21 05:32:28 +0000931- Fix some potential crashes found with failmalloc.
932
Neal Norwitze7563102006-07-17 01:00:16 +0000933- Fix warnings reported by Klocwork's static analysis tool.
934
Neal Norwitz84be93b2006-07-16 01:50:38 +0000935- Bug #1512814, Fix incorrect lineno's when code within a function
936 had more than 255 blank lines.
937
Georg Brandl9dceedb2006-07-12 15:31:17 +0000938- Patch #1521179: Python now accepts the standard options ``--help`` and
939 ``--version`` as well as ``/?`` on Windows.
940
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000941- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000942 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000943 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000944
Tim Peters112aad32006-07-19 00:03:19 +0000945- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000946 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000947 new ``sys._current_frames()`` returns a dictionary with one entry,
948 mapping the faux "thread id" 0 to the current frame.
949
Ronald Oussoren3075e162006-07-25 20:28:55 +0000950- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000951
Ronald Oussoren3075e162006-07-25 20:28:55 +0000952

954-------
955
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000956- Correction of patch #1455898: In the mbcs decoder, set final=False
957 for stream decoder, but final=True for the decode function.
958
Georg Brandl07fec3a2006-08-01 18:49:24 +0000959- os.urandom no longer masks unrelated exceptions like SystemExit or
960 KeyboardInterrupt.
961
Tim Peters4643c2f2006-08-10 22:45:34 +0000962- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000963 shutil.copytree on Windows
964
Georg Brandle34ac7c2006-07-30 11:07:23 +0000965- Bug #1002398: The documentation for os.path.sameopenfile now correctly
966 refers to file descriptors, not file objects.
967
Tim Peterscbdd3502006-09-05 01:47:53 +0000968- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000969 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000970 #1513611, and probably others.
971
Georg Brandledd9b0d2006-07-29 09:33:26 +0000972- Bug #1441397: The compiler module now recognizes module and function
973 docstrings correctly as it did in Python 2.4.
974
Tim Peters6f681472006-07-27 23:44:37 +0000975- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
976 lost that tests are sorted by name before being run. This rarely
977 matters for well-written tests, but can create baffling symptoms if
978 side effects from one test to the next affect outcomes. ``DocTestFinder``
979 has been changed to sort the list of tests it returns.
980
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000981- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000982 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000983
Martin v. Löwis9298eff2006-07-26 12:12:56 +0000984- Bug #978833: Really close underlying socket in _socketobject.close.
985
Georg Brandldb232dc2006-08-20 13:15:43 +0000986- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
987 title().
Georg Brandl0619a322006-07-26 07:40:17 +0000988
Georg Brandlcf0c1722006-07-26 07:23:32 +0000989- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
990 to recursive calls and call it with the failing package name.
991
Martin v. Löwis0b483032006-07-25 09:53:12 +0000992- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
993
Georg Brandlc13c34c2006-07-24 14:09:56 +0000994- Patch #1515343: Fix printing of deprecated string exceptions with a
995 value in the traceback module.
996
Greg Ward48fae7a2006-07-23 16:05:51 +0000997- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
998
Martin v. Löwis426f4a12006-07-18 17:46:31 +0000999- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1000
Brett Cannoncaebe222006-07-18 04:41:36 +00001001- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1002 argument tuple. For arguments where zero is illegal, the value is forced to
1003 the minimum value that is correct. This is to support an undocumented but
1004 common way people used to fill in inconsequential information in the time
1005 tuple pre-2.4.
1006
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001007- Patch #1220874: Update the binhex module for Mach-O.
1008
Barry Warsawb110bad2006-07-21 14:51:07 +00001009- The email package has improved RFC 2231 support, specifically for
1010 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1011 (name*0=<blah>) parameter continuations. This may change the types of
1012 values returned from email.message.Message.get_param() and friends.
1013 Specifically in some cases where non-encoded continuations were used,
1014 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1015 will just return the string (since non-encoded continuations don't have
1016 charset and language parts).
1017
1018 Also, whereas % values were decoded in all parameter continuations, they are
1019 now only decoded in encoded parameter parts.
1020
Ronald Oussoren3075e162006-07-25 20:28:55 +00001021- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1022
1023- Bug #1517996: IDLE now longer shows the default Tk menu when a
1024 path browser, class browser or debugger is the frontmost window on MacOS X
1025
Barry Warsaw00decd72006-07-27 23:43:15 +00001026- Patch #1520294: Support for getset and member descriptors in types.py,
1027 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1028 of an object against these built-in types and more importantly, for getting
1029 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001032Extension Modules
1033-----------------
1034
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001035- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1036 a socket operation on a socket with a timeout, the exception will be
1037 caught correctly. Previously, the exception was not caught.
1038
Thomas Heller1393d6a2006-07-28 21:43:20 +00001039- Patch #1529514: The _ctypes extension is now compiled on more
1040 openbsd target platforms.
1041
Tim Peters9cab5932006-07-28 00:30:00 +00001042- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1043 a memory leak, affecting pickles and deep copies.
1044
Tim Petersbc24eee2006-07-27 01:14:53 +00001045- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001046 Paul Eggert.
1047
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001048- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1049
Thomas Hellerce049a02006-07-14 17:51:14 +00001050- Patch #1521817: Index range checking on ctypes arrays containing
1051 exactly one element enabled again. This allows iterating over these
1052 arrays, without the need to check the array size before.
1053
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001054- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001055 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001056 /dev/null in certain cases; this is now fixed.
1057
Thomas Heller47d7a062006-07-12 08:43:47 +00001058- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1059 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001060
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001061- Because of a misspelled preprocessor symbol, ctypes was always
1062 compiled without thread support; this is now fixed.
1063
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001064- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1065 methods now allow their database parameter to be None as the
1066 sleepycat API allows.
1067
Matt Flemingec926502006-07-28 11:27:27 +00001068- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1069 bluetooth API compared with Linux and FreeBSD.
1070
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001071Tests
1072-----
1073
1074- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1075 how long the test file should take to play. Now accepts taking 2.93 secs
1076 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1077
Georg Brandl4793aa32006-07-28 18:31:39 +00001078- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1079 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1080 run via ``regrtest.py``. Now they do.

1084
1085- Bug #1439538: Drop usage of test -e in configure as it is not portable.
1086
Ronald Oussoren26cad082006-08-01 21:00:57 +00001087Mac
1088---
1089
1090- PythonLauncher now works correctly when the path to the script contains
1091 characters that are treated specially by the shell (such as quotes).
1092
1093- Bug #1527397: PythonLauncher now launches scripts with the working directory
1094 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001095 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001096 expect.

1105-----------------
1106
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001107- Bug #1441486: The literal representation of -(sys.maxint - 1)
1108 again evaluates to a int object, not a long.
1109
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001110- Bug #1501934: The scope of global variables that are locally assigned
1111 using augmented assignment is now correctly determined.
1112
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001113- Bug #927248: Recursive method-wrapper objects can now safely
1114 be released.
1115
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001116- Bug #1417699: Reject locale-specific decimal point in float()
1117 and atof().
1118
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001119- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1120 omit a default "error" argument for NULL pointer. This allows
1121 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001122
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001123- Bug #1519018: 'as' is now validated properly in import statements.
1124
Neal Norwitz28746ab2006-07-09 22:14:42 +00001125- On 64 bit systems, int literals that use less than 64 bits are
1126 now ints rather than longs.
1127
Neal Norwitzed657552006-07-10 00:04:44 +00001128- Bug #1512814, Fix incorrect lineno's when code at module scope
1129 started after line 256.
1130
Tim Peters32a83612006-07-10 21:08:24 +00001131- New function ``sys._current_frames()`` returns a dict mapping thread
1132 id to topmost thread stack frame. This is for expert use, and is
1133 especially useful for debugging application deadlocks. The functionality
1134 was previously available in Fazal Majid's ``threadframe`` extension
1135 module, but it wasn't possible to do this in a wholly threadsafe way from
1136 an extension.

Martin v. Löwis77621582006-07-30 13:27:31 +00001141- Bug #1257728: Mention Cygwin in distutils error message about a missing
1142 VS 2003.
1143
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001144- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1145
Tim Peters32a83612006-07-10 21:08:24 +00001146- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001147 environment variable to be set in order to the SDK environment
1148 for finding the compiler, include files, etc.

1153
Thomas Woutersadd19112006-07-05 11:03:49 +00001154- string.Template() now correctly handles tuple-values. Previously,
1155 multi-value tuples would raise an exception and single-value tuples would
1156 be treated as the value they contain, instead.
1157
Martin v. Löwisede77f52006-07-03 13:01:35 +00001158- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1159 even if some data are received.
1160
Martin v. Löwis45482392006-07-03 12:28:58 +00001161- Bug #1267547: Put proper recursive setup.py call into the
1162 spec file generated by bdist_rpm.
1163
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001164- Bug #1514693: Update turtle's heading when switching between
1165 degrees and radians.
1166
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001167- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001168 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001169
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001170- Bug #1514703: Only setup canvas window in turtle when the canvas
1171 is created.
1172
Martin v. Löwis7596e832006-07-01 15:33:37 +00001173- Bug #1513223: .close() of a _socketobj now releases the underlying
1174 socket again, which then gets closed as it becomes unreferenced.
1175
Fred Drake10497c82006-06-29 02:57:48 +00001176- Bug #1504333: Make sgmllib support angle brackets in quoted
1177 attribute values.

Georg Brandl1be63af2006-06-28 20:23:25 +00001182- Fix a bug in the turtle module's end_fill function.
1183
Brett Cannon53ab5b72006-06-22 16:49:14 +00001184- Bug #1510580: The 'warnings' module improperly required that a Warning
1185 category be either a types.ClassType and a subclass of Warning. The proper
1186 check is just that it is a subclass with Warning as the documentation states.
1187
Georg Brandlad29e632006-06-21 17:45:17 +00001188- The compiler module now correctly compiles the new try-except-finally
1189 statement (bug #1509132).
1190
Neal Norwitz60373cd2006-06-22 06:30:50 +00001191- The wsgiref package is now installed properly on Unix.
1192
Vinay Sajip28e57612006-07-01 10:45:20 +00001193- A bug was fixed in logging.config.fileConfig() which caused a crash on
1194 shutdown when fileConfig() was called multiple times.
1195
Gerhard Häring762fbd32006-07-02 17:48:30 +00001196- The sqlite3 module did cut off data from the SQLite database at the first
1197 null character before sending it to a custom converter. This has been fixed
1198 now.
1199
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001200Extension Modules
1201-----------------
1202
Tim Peters112aad32006-07-19 00:03:19 +00001203- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1204 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1205 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001206
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001207- Assigning None to pointer type fields in ctypes structures possible
1208 overwrote the wrong fields, this is fixed now.
1209
1210- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1211 on non-Windows platforms.
1212
1213- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1214 integer or long, without range checking.
1215
1216- Patch #1517790: It is now possible to use custom objects in the ctypes
1217 foreign function argtypes sequence as long as they provide a from_param
1218 method, no longer is it required that the object is a ctypes type.
1219
1220- The '_ctypes' extension module now works when Python is configured
1221 with the --without-threads option.
1222
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001223- Bug #1513646: os.access on Windows now correctly determines write
1224 access, again.
1225
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001226- Bug #1512695: cPickle.loads could crash if it was interrupted with
1227 a KeyboardInterrupt.
1228
Neal Norwitza12aa882006-07-06 06:45:08 +00001229- Bug #1296433: parsing XML with a non-default encoding and
1230 a CharacterDataHandler could crash the interpreter in pyexpat.
1231

Martin v. Löwisd73168d2006-07-14 09:58:55 +00001237- Automate Windows build process for the Win64 SSL module.
1238
Tim Peters32a83612006-07-10 21:08:24 +00001239- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001240 Previously, the slight difference could cause compilation errors of the
1241 'zlib' module on systems with more than one version of zlib.
1242
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001243- The MSI compileall step was fixed to also support a TARGETDIR

Anthony Baxter51bcb682006-04-05 14:51:42 +00001273
1274Core and builtins
1275-----------------
1276
Georg Brandla56b9152006-06-19 06:35:54 +00001277- Patch #1507676: Error messages returned by invalid abstract object operations
1278 (such as iterating over an integer) have been improved and now include the
1279 type of the offending object to help with debugging.
1280
Brett Cannonea3912b2006-06-13 21:46:41 +00001281- Bug #992017: A classic class that defined a __coerce__() method that returned
1282 its arguments swapped would infinitely recurse and segfault the interpreter.
1283
Neal Norwitz909eb122006-06-12 02:13:21 +00001284- Fix the socket tests so they can be run concurrently.
1285
Neal Norwitzb9845e72006-06-12 02:11:18 +00001286- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001287 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001288
Brett Cannon22565aa2006-06-09 22:31:23 +00001289- Bug #532646: object.__call__() will continue looking for the __call__
1290 attribute on objects until one without one is found. This leads to recursion
1291 when you take a class and set its __call__ attribute to an instance of the
1292 class. Originally fixed for classic classes, but this fix is for new-style.
1293 Removes the infinite_rec_3 crasher.
1294
Georg Brandl24250812006-06-09 18:45:48 +00001295- The string and unicode methods startswith() and endswith() now accept
1296 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1297
Brett Cannonde3b0522006-06-08 17:00:45 +00001298- Buffer objects, at the C level, never used the char buffer
1299 implementation even when the char buffer for the wrapped object was
1300 explicitly requested (originally returned the read or write buffer).
1301 Now a TypeError is raised if the char buffer is not present but is
1302 requested.
1303
Georg Brandlddbaa662006-06-04 21:56:52 +00001304- Patch #1346214: Statements like "if 0: suite" are now again optimized
1305 away like they were in Python 2.4.
1306
Georg Brandlb7c8f542006-05-27 12:30:25 +00001307- Builtin exceptions are now full-blown new-style classes instead of
1308 instances pretending to be classes, which speeds up exception handling
1309 by about 80% in comparison to 2.5a2.
1310
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001311- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1312 Unicode 4.1.
1313
Georg Brandlf4ef1162006-05-26 18:03:31 +00001314- Patch #921466: sys.path_importer_cache is now used to cache valid and
1315 invalid file paths for the built-in import machinery which leads to
1316 fewer open calls on startup.
1317
Tim Peters696cf432006-05-24 21:10:40 +00001318- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1319 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1320 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1321 the number of input digits (it was and remains linear-time for bases
1322 2, 4, 8, 16 and 32).
1323
Tim Petersb713ec22006-05-23 18:45:30 +00001324- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1325 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1326 an integer close to ``sys.maxint``. This was repaired by patch
1327 #1335972, which also gives a nice speedup.
1328
Richard Jonescebbefc2006-05-23 18:28:17 +00001329- Patch #1337051: reduced size of frame objects.
1330
1331- PyErr_NewException now accepts a tuple of base classes as its
1332 "base" parameter.
1333
Richard Jones7c88dcc2006-05-23 10:37:38 +00001334- Patch #876206: function call speedup by retaining allocated frame
1335 objects.
1336
Georg Brandl7b90e162006-05-18 07:01:27 +00001337- Bug #1462152: file() now checks more thoroughly for invalid mode
1338 strings and removes a possible "U" before passing the mode to the
1339 C library function.
1340
Neal Norwitz1004a532006-05-15 07:17:23 +00001341- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1342
Neal Norwitz373f0a72006-05-15 07:04:36 +00001343- Bug #1487966: Fix SystemError with conditional expression in assignment
1344
Martin v. Löwis879768d2006-05-11 13:28:43 +00001345- WindowsError now has two error code attributes: errno, which carries
1346 the error values from errno.h, and winerror, which carries the error
1347 values from winerror.h. Previous versions put the winerror.h values
1348 (from GetLastError()) into the errno attribute.
1349
Martin v. Löwis77736712006-05-04 05:51:03 +00001350- Patch #1475845: Raise IndentationError for unexpected indent.
1351
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001352- Patch #1479181: split open() and file() from being aliases for each other.
1353
Tim Peters44bd9862006-06-01 13:49:23 +00001354- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1355 methods were always silently ignored by dictionaries when comparing keys.
1356 They are now passed through (except when using the C API function
1357 ``PyDict_GetItem()``, whose semantics did not change).
1358
1359- Bug #1456209: In some obscure cases it was possible for a class with a
1360 custom ``__eq__()`` method to confuse dict internals when class instances
1361 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1362 No, you don't have any code that did this ;-)

1370
Brett Cannon6ee7d012006-06-08 16:23:04 +00001371- Change binascii.hexlify to accept a read-only buffer instead of only a char
1372 buffer and actually follow its documentation.
1373
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001374- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1375
Nick Coghlanc649ec52006-05-29 12:43:05 +00001376- Patch #1478788 (modified version): The functional extension module has
1377 been renamed to _functools and a functools Python wrapper module added.
1378 This provides a home for additional function related utilities that are
1379 not specifically about functional programming. See PEP 309.
1380
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001381- Patch #1493701: performance enhancements for struct module.

1386 copy() method.
1387
Andrew MacIntyre92913322006-06-13 15:04:24 +00001388- Patch #1454481: thread stack size is now tunable at runtime for thread
1389 enabled builds on Windows and systems with Posix threads support.
1390
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001391- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1392 (up to the system limit of 32K characters).
1393
1394- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1395 As a result, these functions now raise WindowsError instead of OSError.
1396
Tim Peters7a822da2006-05-25 21:50:17 +00001397- ``time.clock()`` on Win64 should use the high-performance Windows
1398 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1399 Windows platforms).
1400
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001401- Calling Tk_Init twice is refused if the first call failed as that
1402 may deadlock.
1403
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001404- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1405 accept it without potentially using an uninitialized pointer.
1406
1407- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1408 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

1415 parameter is supplied. [SF pybsddb bug #1477863]
1416
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001417- bsddb: the __len__ method of a DB object has been fixed to return correct
1418 results. It could previously incorrectly return 0 in some cases.
1419 Fixes SF bug 1493322 (pybsddb bug 1184012).
1420
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001421- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1422 aborts the db transaction safely when a modifier callback fails.
1423 Fixes SF python patch/bug #1408584.
1424
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001425- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001426 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001427 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1428 database calls that would previously deadlock. [SF python bug #775414]

1458 double-byte encodings.
1459
Tim Peters43898b42006-06-14 04:09:25 +00001460- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1461 guarantee that adjacent triples in the return list always describe
1462 non-adjacent blocks. Previously, a pair of matching blocks could end
1463 up being described by multiple adjacent triples that formed a partition
1464 of the matching pair.

1473
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001474- The wsgiref package has been added to the standard library.
1475
Nick Coghlan676725d2006-06-08 13:54:49 +00001476- The functions update_wrapper() and wraps() have been added to the functools
1477 module. These make it easier to copy relevant metadata from the original
1478 function when writing wrapper functions.
1479
Tim Petersd6a9eef2006-06-05 01:48:21 +00001480- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1481 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001482
Martin v. Löwis3f767792006-06-04 19:36:28 +00001483- Patch #1359618: Speed up charmap encoder by using a trie structure
1484 for lookup.
1485
Tim Petersd609b1a2006-06-02 23:22:51 +00001486- The functions in the ``pprint`` module now sort dictionaries by key
1487 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1488 if and only if its display required more than one line, although that
1489 wasn't documented. The new behavior increases predictability; e.g.,
1490 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1491
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001492- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1493 (thanks for J. J. Lee).
1494
Georg Brandl2b330372006-05-28 20:23:12 +00001495- Patch #1496206: improve urllib2 handling of passwords with respect to
1496 default HTTP and HTTPS ports.
1497
George Yoshidaf3c65de2006-05-28 16:39:09 +00001498- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1499
Bob Ippolito7298f272006-05-23 18:43:47 +00001500- Patch #1281707: speed up gzip.readline.
1501
Georg Brandlb89316f2006-05-17 15:51:16 +00001502- Patch #1180296: Two new functions were added to the locale module:
1503 format_string() to get the effect of "format % items" but locale-aware,
1504 and currency() to format a monetary number with currency sign.
1505
Georg Brandle3a25832006-05-17 14:56:04 +00001506- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1507 and several features added, such as speed and geometry control.
1508
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001509- Patch #1488881: add support for external file objects in bz2 compressed
1510 tarfiles.
1511
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001512- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1513 stdout arguments, making it possible to redirect input and output
1514 for remote debugging.
1515
1516- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1517 a couple of issues, notably handling of long file names using the
1518 GNU LONGNAME extension.
1519
1520- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1521 new flag when ``name`` is already the name of an option flag.
1522
1523- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1524 package.
1525
1526- Patch #1472854: make the rlcompleter.Completer class usable on non-
1527 UNIX platforms.
1528
1529- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1530
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001531- Bug #1472827: correctly escape newlines and tabs in attribute values in
1532 the saxutils.XMLGenerator class.

Neal Norwitz58e28882006-05-19 07:00:58 +00001544- Bug/Patch #1481770: Use .so extension for shared libraries on HP-UX for ia64.
1545
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001546- Patch #1471883: Add --enable-universalsdk.

1561
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001562What's New in Python 2.5 alpha 2?
1563=================================
1564
1565*Release date: 27-APR-2006*
1566
1567Core and builtins
1568-----------------
1569
Thomas Heller1b046642006-04-18 18:51:06 +00001570- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1571 by converting these apis from macros into exported functions again:
1572
1573 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1574 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1575 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1576 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1577 PyRun_String Py_CompileString
1578
Martin v. Löwis45294a92006-04-18 06:24:08 +00001579- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1580
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001581- All uses of PyStructSequence_InitType have been changed to initialize
1582 the type objects only once, even if the interpreter is initialized
1583 multiple times.
1584
Neal Norwitz61546162006-04-14 05:20:28 +00001585- Bug #1454485, array.array('u') could crash the interpreter. This was
1586 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1587 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1588
1589- Py_UNICODE is unsigned. It was always documented as unsigned, but
1590 due to a bug had a signed value in previous versions.
1591
Tim Peters3a5e8b12006-04-11 01:44:07 +00001592- Patch #837242: ``id()`` of any Python object always gives a positive
1593 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1594 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001595 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001596 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001597
Tim Peters3a5e8b12006-04-11 01:44:07 +00001598 def __hash__(self):
1599 return id(self) # WRONG
1600
1601 because a hash result must be a (short) Python int but it was always
1602 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001603 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001604 was always usable as a hash value before this patch. That's no longer
1605 necessarily so.
1606
1607- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001608 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001609 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001610 #1454844)
1611
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001612- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1613 involving generators that have paused outside of any ``try`` or ``with``
1614 blocks. (In 2.5a1, a paused generator that was part of a reference
1615 cycle could not be garbage collected, regardless of whether it was
1616 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001617
Anthony Baxter51bcb682006-04-05 14:51:42 +00001618Extension Modules

1620
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001621- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1622 is a macro.
1623
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001624- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1625 fails with an error condition.
1626
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001627- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1628
1629- Bug #1117761: bsddb.*open() no longer raises an exception when using
1630 the cachesize parameter.
1631
1632- Bug #1149413: bsddb.*open() no longer raises an exception when using
1633 a temporary db (file=None) with the 'n' flag to truncate on open.
1634
1635- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1636 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001637
Armin Rigoa9017c32006-04-19 11:50:27 +00001638- Patch #1062014: AF_UNIX sockets under Linux have a special
1639 abstract namespace that is now fully supported.
1640

1642-------
1643
Peter Astrand7d1d4362006-07-14 14:04:45 +00001644- Bug #1223937: subprocess.CalledProcessError reports the exit status
1645 of the process using the returncode attribute, instead of
1646 abusing errno.
1647
Tim Peters711bf302006-04-25 03:31:36 +00001648- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1649 a doctest to be skipped (the code is not run, and the expected output
1650 or exception is ignored).
1651
Nick Coghlanda2268f2006-04-24 04:37:15 +00001652- Fixed contextlib.nested to cope with exceptions being raised and
1653 caught inside exit handlers.
1654
Greg Wardab05edc2006-04-23 03:47:58 +00001655- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1656 hex, octal, or binary; add ``append_const`` action; keep going if
1657 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1658 added ``epilog`` for better help generation).
1659
Tim Peters21fbd572006-04-21 21:18:10 +00001660- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1661 called from a thread spawned as a side effect of importing a module.
1662
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001663- The pydoc module now supports documenting packages contained in
1664 .zip or .egg files.
1665
1666- The pkgutil module now has several new utility functions, such
1667 as ``walk_packages()`` to support working with packages that are either
1668 in the filesystem or zip files.
1669
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001670- The mailbox module can now modify and delete messages from
1671 mailboxes, in addition to simply reading them. Thanks to Gregory
1672 K. Johnson for writing the code, and to the 2005 Google Summer of
1673 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001674
Tim Petersc7605f22006-04-17 21:12:33 +00001675- The ``__del__`` method of class ``local`` in module ``_threading_local``
1676 returned before accomplishing any of its intended cleanup.
1677
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001678- Patch #790710: Add breakpoint command lists in pdb.
1679
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001680- Patch #1063914: Add Tkinter.Misc.clipboard_get().

1683
Anthony Baxtere29002c2006-04-12 12:07:31 +00001684- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1685 Windows. Bug #1469163.
1686
Phillip J. Eby47032112006-04-11 01:07:43 +00001687- The warnings, linecache, inspect, traceback, site, and doctest modules
1688 were updated to work correctly with modules imported from zipfiles or
1689 via other PEP 302 __loader__ objects.
1690
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001691- Patch #1467770: Reduce usage of subprocess._active to processes which
1692 the application hasn't waited on.
1693

1702-----
1703
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001704- The Makefile now has a reindent target, which runs reindent.py on
1705 the library.
1706
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001707- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis0f48d982006-04-14 14:34:26 +00001711- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1712 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001713 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001714 CXX from --with-cxx-main, see description in README.
1715
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001716- Patch #1429775: Link extension modules with the shared libpython.
1717
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001718- Fixed a libffi build problem on MIPS systems.
1719
Tim Peters8931ff12006-05-13 23:28:20 +00001720- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1721 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1722 and "%zu" for unsigned integers of type ``size_t``.
1723
Anthony Baxter51bcb682006-04-05 14:51:42 +00001724Tests
1725-----
1726
Nick Coghlanda2268f2006-04-24 04:37:15 +00001727- test_contextlib now checks contextlib.nested can cope with exceptions
1728 being raised and caught inside exit handlers.
1729
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001730- test_cmd_line now checks operation of the -m and -c command switches
1731
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001732- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1733 it separately and by hand. It also wasn't cleaning up its changes to
1734 the current Decimal context.
1735
Thomas Woutersabd08882006-04-26 15:53:30 +00001736- regrtest.py now has a -M option to run tests that test the new limits of
1737 containers, on 64-bit architectures. Running these tests is only sensible
1738 on 64-bit machines with more than two gigabytes of memory. The argument
1739 passed is the maximum amount of memory for the tests to use.

Tim Petersb06d28c2006-05-12 01:57:59 +00001750- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1751
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001752- PEP 343: Added Context Types section to the library reference
1753 and attempted to bring other PEP 343 related documentation into
1754 line with the implementation and/or python-dev discussions.
1755
Tim Peters8dc73d22006-04-24 02:03:16 +00001756- Bug #1337990: clarified that ``doctest`` does not support examples

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001760What's New in Python 2.5 alpha 1?
1761=================================
1762
Anthony Baxterebed3f62006-04-03 15:03:44 +00001763*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001764
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001765Core and builtins
1766-----------------
1767
Nick Coghlan43832302006-04-23 17:04:07 +00001768- PEP 338: -m command line switch now delegates to runpy.run_module
1769 allowing it to support modules in packages and zipfiles
1770
Martin v. Löwisc661b882006-04-20 04:54:23 +00001771- On Windows, .DLL is not an accepted file name extension for
1772 extension modules anymore; extensions are only found if they
1773 end in .PYD.
1774
Martin v. Löwisea62d252006-04-03 10:56:49 +00001775- Bug #1421664: sys.stderr.encoding is now set to the same value as
1776 sys.stdout.encoding.
1777
Neal Norwitz92e212f2006-04-03 04:48:37 +00001778- __import__ accepts keyword arguments.
1779
Georg Brandlccadf842006-03-31 18:54:53 +00001780- Patch #1460496: round() now accepts keyword arguments.
1781
Anthony Baxter262c00a2006-03-30 10:53:17 +00001782- Fixed bug #1459029 - unicode reprs were double-escaped.
1783
Hye-Shik Changd478f342006-03-23 12:32:36 +00001784- Patch #1396919: The system scope threads are reenabled on FreeBSD
1785 5.4 and later versions.
1786
Neal Norwitze98ccf62006-03-23 05:39:47 +00001787- Bug #1115379: Compiling a Unicode string with an encoding declaration
1788 now gives a SyntaxError.
1789
Georg Brandlabd1ff82006-03-18 07:59:59 +00001790- Previously, Python code had no easy way to access the contents of a
1791 cell object. Now, a ``cell_contents`` attribute has been added
1792 (closes patch #1170323).
1793
Tim Peterscf79aac2006-03-16 01:14:46 +00001794- Patch #1123430: Python's small-object allocator now returns an arena to
1795 the system ``free()`` when all memory within an arena becomes unused
1796 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1797 freed. Some applications will see a drop in virtual memory size now,
1798 especially long-running applications that, from time to time, temporarily
1799 use a large number of small objects. Note that when Python returns an
1800 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001801 platform C library will in turn return that memory to the operating system.
1802 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001803 appears to be effective at least on Microsoft C and gcc-based systems.
1804 Thanks to Evan Jones for hard work and patience.
1805
Georg Brandl533ff6f2006-03-08 18:09:27 +00001806- Patch #1434038: property() now uses the getter's docstring if there is
1807 no "doc" argument given. This makes it possible to legitimately use
1808 property() as a decorator to produce a read-only property.
1809
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001810- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1811 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1812 of requiring an int or long in slicing and a few other contexts, enabling
1813 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1814
Neal Norwitz995acdf2006-03-07 05:01:00 +00001815- Fixed various bugs reported by Coverity's Prevent tool.
1816
Brett Cannonbf364092006-03-01 04:25:17 +00001817- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1818 new exception base class, BaseException, which has a new message attribute.
1819 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1820 Raising a string exception now raises a DeprecationWarning.
1821
Thomas Woutersfb609f42006-02-28 16:37:25 +00001822- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1823 explicitly relative, using 'from .module import name' to mean 'from the same
1824 package as this module is in. Imports without dots still default to the
1825 old relative-then-absolute, unless 'from __future__ import
1826 absolute_import' is used.
1827
Brett Cannona7446e32006-02-27 23:39:10 +00001828- Properly check if 'warnings' raises an exception (usually when a filter set
1829 to "error" is triggered) when raising a warning for raising string
1830 exceptions.
1831
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001832- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001833 The name was removed from Include/code.h.
1834
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001835- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001836
Guido van Rossum1968ad32006-02-25 22:38:04 +00001837- Patch 1433928:
1838 - The copy module now "copies" function objects (as atomic objects).
1839 - dict.__getitem__ now looks for a __missing__ hook before raising
1840 KeyError.
1841
Tim Peters84ef21c2006-02-28 20:39:06 +00001842- PEP 343: with statement implemented. Needs ``from __future__ import
1843 with_statement``. Use of 'with' as a variable will generate a warning.
1844 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001845 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001846 The following objects have __context__ methods:
1847 - The built-in file type.
1848 - The thread.LockType type.
1849 - The following types defined by the threading module:
1850 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1851 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001852
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001853- Fix the encodings package codec search function to only search
1854 inside its own package. Fixes problem reported in patch #1433198.
1855
1856 Note: Codec packages should implement and register their own
1857 codec search function. PEP 100 has the details.
1858
Tim Peters9ea89d22006-06-04 03:26:02 +00001859- PEP 353: Using ``Py_ssize_t`` as the index type.
1860
1861- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1862 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1863 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1864 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1865 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001866
Neal Norwitzfc76d632006-01-10 06:03:13 +00001867- Patch #1400181, fix unicode string formatting to not use the locale.
1868 This is how string objects work. u'%f' could use , instead of .
1869 for the decimal point. Now both strings and unicode always use periods.
1870
Neal Norwitz671b9e32006-01-09 07:07:12 +00001871- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1872 configure would break checking curses.h.
1873
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001874- Bug #959576: The pwd module is now builtin. This allows Python to be
1875 built on UNIX platforms without $HOME set.
1876
Neal Norwitzc10978f2005-12-19 06:07:16 +00001877- Bug #1072182, fix some potential problems if characters are signed.
1878
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001879- Bug #889500, fix line number on SyntaxWarning for global declarations.
1880
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001881- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1882
Neal Norwitze7214a12005-12-18 05:03:17 +00001883- Support for converting hex strings to floats no longer works.
1884 This was not portable. float('0x3') now raises a ValueError.
1885
Barry Warsaw2a38a862005-12-18 01:27:35 +00001886- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001887 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001888 is now displayed in interactive prompt banner.
1889
Georg Brandlfa166682005-12-17 21:45:17 +00001890- Implementation of PEP 341 - Unification of try/except and try/finally.
1891 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001892 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001893
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001894- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1895 now encodes backslash correctly.
1896
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001897- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1898
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001899- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001900 and long longs.
1901
Neal Norwitz67715f02005-11-09 06:59:35 +00001902- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001903 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001904 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001905
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001906- Replaced most Unicode charmap codecs with new ones using the
1907 new Unicode translate string feature in the builtin charmap
1908 codec; the codecs were created from the mapping tables available
1909 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1910 encodings now include a mapping for the Apple logo)
1911
Tim Peterse3547fd2005-12-16 23:13:57 +00001912- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001913
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001914- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001915
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001916- A new AST parser implementation was completed. The abstract
1917 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001918 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001919
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001920- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001921 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1922
Neal Norwitz708e51a2005-10-03 04:48:15 +00001923- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1924
Neal Norwitz11bd1192005-10-03 00:54:56 +00001925- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1926 Provide a warning when a directory is passed on the command line.
1927
Neal Norwitz40d37812005-10-02 01:48:49 +00001928- Fix segfault with invalid coding.
1929
1930- SF bug #772896: unknown encoding results in MemoryError.
1931
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001932- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001933 supported a __len__() method which evaluated to False when the iterator
1934 was empty.
1935
Guido van Rossum630db602005-09-20 18:49:54 +00001936- On 64-bit platforms, when __len__() returns a value that cannot be
1937 represented as a C int, raise OverflowError.
1938
Skip Montanarof8948ca2005-09-19 03:54:46 +00001939- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001940 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001941
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001942- SF bug #893549: parsing keyword arguments was broken with a few format
1943 codes.
1944
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001945- Changes donated by Elemental Security to make it work on AIX 5.3
1946 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1947 bug #105470: test_pwd fails on 64bit system (Opteron).
1948
Guido van Rossum539c6622005-09-14 17:49:54 +00001949- Changes donated by Elemental Security to make it work on HP-UX 11 on
1950 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1951
Georg Brandl4550b8d2005-08-26 06:43:52 +00001952- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001953 (fixes bug #1119418).
1954
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001955- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1956
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001957- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1958 exceptions that cause a function to exit.
1959
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001960- The implementation of set() and frozenset() was revised to use its
1961 own internal data structure. Memory consumption is reduced by 1/3
1962 and there are modest speed-ups as well. The API is unchanged.
1963
Tim Petersde7990b2005-07-17 23:45:23 +00001964- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1965
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001966- SF bug #1229429: PyObject_CallMethod failed to decrement some
1967 reference counts in some error exit cases.
1968
Tim Petersecc6e6a2005-07-10 22:30:55 +00001969- SF bug #1185883: Python's small-object memory allocator took over
1970 a block managed by the platform C library whenever a realloc specified
1971 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001972 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001973 portable way to copy data from the C-managed block into Python's
1974 small-object space without risking a memory fault. Python's small-object
1975 realloc now leaves such blocks under the control of the platform C
1976 realloc.
1977
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001978- SF bug #1232517: An overflow error was not detected properly when
1979 attempting to convert a large float to an int in os.utime().
1980
Raymond Hettinger3296e692005-06-29 23:29:56 +00001981- SF bug #1224347: hex longs now print with lowercase letters just
1982 like their int counterparts.
1983
Michael W. Hudson188d4362005-06-20 16:52:57 +00001984- SF bug #1163563: the original fix for bug #1010677 ("thread Module
1985 Breaks PyGILState_Ensure()") broke badly in the case of multiple
1986 interpreter states; back out that fix and do a better job (see
1987 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
1988 for a longer write-up of the problem).
1989
Michael W. Hudsondf888462005-06-03 14:41:55 +00001990- SF patch #1180995: marshal now uses a binary format by default when
1991 serializing floats.
1992
Michael W. Hudsonda85a902005-06-01 11:34:22 +00001993- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
1994 the routines that promise to produce IEEE 754 binary representations
1995 of floats now simply copy bytes around.
1996
Skip Montanarobbf12ba2005-05-20 03:07:06 +00001997- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
1998 278.
1999
Brett Cannonc3647ac2005-04-26 03:45:26 +00002000- patch #1109424: int, long, float, complex, and unicode now check for the
2001 proper magic slot for type conversions when subclassed. Previously the
2002 magic slot was ignored during conversion. Semantics now match the way
2003 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002004 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002005 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002006 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002007
Barry Warsawc8d907c2005-04-19 23:43:40 +00002008- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2009 NULL, now raise an AttributeError when attempting to set or delete the
2010 attribute. Previously a TypeError was raised, but this was inconsistent
2011 with the equivalent pure-Python implementation.
2012
Michael W. Hudson774479c2005-04-18 08:46:17 +00002013- It is now safe to call PyGILState_Release() before
2014 PyEval_InitThreads() (note that if there is reason to believe there
2015 are multiple threads around you still must call PyEval_InitThreads()
2016 before using the Python API; this fix is for extension modules that
2017 have no way of knowing if Python is multi-threaded yet).
2018
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002019- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2020 disabled caused a crash.
2021
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002022- Bug #1165306: instancemethod_new allowed the creation of a method
2023 with im_class == im_self == NULL, which caused a crash when called.
2024
Tim Petersecc6e6a2005-07-10 22:30:55 +00002025- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002026 fixes the crash seen in bug #1165761
2027
Raymond Hettinger96229b12005-03-11 06:49:40 +00002028- Added two new builtins, any() and all().
2029
Brett Cannon409d8f22005-03-05 06:47:57 +00002030- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002031 (e.g., ``class C(): pass`` is no longer a syntax error).
2032 Patch #1176012 added support to the 'parser' module and 'compiler' package
2033 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002034
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002035- Patch #1115086: Support PY_LONGLONG in structmember.
2036
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002037- Bug #1155938: new style classes did not check that __init__() was
2038 returning None.
2039
Tim Petersecc6e6a2005-07-10 22:30:55 +00002040- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002041 ('\') with a specific error message.
2042

2068 calling __str__ on the argument returns a unicode instance.
2069
Tim Petersf4e69282006-02-27 17:15:31 +00002070- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2071 current thread state when the auto-GIL-state machinery knows about
2072 it (since the thread state is being deleted, continuing to remember it
2073 can't help, but can hurt if another thread happens to get created with
2074 the same thread id).

2283
Anthony Baxterc51ee692006-04-01 00:57:31 +00002284- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002285 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002286 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002287 module will not be built.

Tim Petersc17976e2006-04-01 00:26:53 +00002289- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2290 aren't officially supported here, and trying to use them will probably

2312
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002313- email 4.0 package now integrated. This is largely the same as the email 3.0
2314 package that was included in Python 2.3, except that PEP 8 module names are
2315 now used (e.g. mail.message instead of email.Message). The MIME classes
2316 have been moved to a subpackage (e.g. email.mime.text instead of
2317 email.MIMEText). The old names are still supported for now. Several
2318 deprecated Message methods have been removed and lots of bugs have been
2319 fixed. More details can be found in the email package documentation.

2322 (a subclass of tuple) that provides incremental decoders and encoders
2323 (a way to use stateful codecs without the stream API). Python functions
2324 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2325 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2326 have been added.

2329 a ValueError instead of a StopIteration now (like file and cString.String do).

Tim Peterse3547fd2005-12-16 23:13:57 +00002405 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2406 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2407 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2408 Ronald L. Rivest offered this advice for Python:
2409
2410 "The consensus of researchers in this area (at least as
2411 expressed at the NIST Hash Function Workshop 10/31/05),
2412 is that SHA-256 is a good choice for the time being, but
2413 that research should continue, and other alternatives may
2414 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002415

Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00002571- Patch #1049151: xdrlib now unpacks booleans as True or False.
2572
Raymond Hettingerbab41432005-02-05 01:31:19 +00002573- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2574
Guido van Rossumd0641422005-02-03 15:01:24 +00002575- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2576 disables recursive traversal through instance attributes, which can
2577 be exploited in various ways.
2578
Tim Peterse3547fd2005-12-16 23:13:57 +00002579- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002580 flags on the HTTP listening socket.
2581
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002582- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2583 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2584
Fred Drakefbdeaad2006-07-29 16:56:15 +00002585- Patches #893642, #1039083: add allow_none, encoding arguments to
2586 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.

2589
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002590- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2591
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002592- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2593
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002594- Enhancements to the csv module:
2595
2596 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002597 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002598 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002599 + Dialect parameter parsing has been re-implemented to improve error
2600 reporting.
2601 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2602 dictates.
2603 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002604 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002605 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002606 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2607 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002608 + reader now allows \r characters to be quoted (previously it only allowed
2609 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002610 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002611 + Dialect classes passed to the module are no longer instantiated by
2612 the module before being parsed (the former validation scheme required
2613 this, but the mechanism was unreliable).
2614 + The dialect registry now contains instances of the internal
2615 C-coded dialect type, rather than references to python objects.
2616 + the internal c-coded dialect type is now immutable.
2617 + register_dialect now accepts the same keyword dialect specifications
2618 as the reader and writer, allowing the user to register dialects
2619 without first creating a dialect class.
2620 + a configurable limit to the size of parsed fields has been added -
2621 previously, an unmatched quote character could result in the entire
2622 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002623 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002624 the parser field size limit (returning the former limit). The initial
2625 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002626 + A line_num attribute has been added to the reader object, which tracks
2627 the number of lines read from the source iterator. This is not
2628 the same as the number of records returned, as records can span
2629 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002630 + reader and writer objects were not being registered with the cyclic-GC.
2631 This has been fixed.
2632
Brett Cannone6539c42005-01-08 02:43:53 +00002633- _DummyThread objects in the threading module now delete self.__block that is
2634 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2635 lock primitives tend to be limited in number and thus should not be wasted on
2636 a _DummyThread object. Fixes bug #1089632.
2637
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002638- The imghdr module now detects Exif files.
2639
Raymond Hettinger6065d322004-12-20 23:51:53 +00002640- StringIO.truncate() now correctly adjusts the size attribute.
2641 (Bug #951915).
2642
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002643- locale.py now uses an updated locale alias table (built using
2644 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2645 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002646 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002647
Raymond Hettinger3557f422004-12-07 12:02:02 +00002648- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2649
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002650- the pickle module no longer accepts the deprecated None option in the
2651 args tuple returned by __reduce__().
2652
Brett Cannon84667c02004-12-07 03:25:18 +00002653- optparse now optionally imports gettext. This allows its use in setup.py.
2654
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002655- the pickle module no longer uses the deprecated bin parameter.
2656
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002657- the shelve module no longer uses the deprecated binary parameter.
2658
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002659- the pstats module no longer uses the deprecated ignore() method.
2660
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002661- the filecmp module no longer uses the deprecated use_statcache argument.
2662
Raymond Hettinger664347b2004-12-04 21:21:53 +00002663- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2664 extended or overridden by subclasses. Formerly, the subclassed method would
2665 be ignored by the rest of the module. (Bug #1078905).
2666
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002667- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002668 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002669
Walter Dörwald36733692004-12-22 12:50:50 +00002670- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2671 once when a size argument is given. This prevents a buffer overflow in the
2672 tokenizer with very long source lines.
2673
Barry Warsaw538561e2006-01-01 21:48:54 +00002674- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2675 immediately after creating the object, without any intervening
2676 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002677
Skip Montanaro05885812005-01-16 20:48:27 +00002678- The reconvert.quote function can now emit triple-quoted strings. The
2679 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002680
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002681- ``UserString.MutableString`` now supports negative indices in
2682 ``__setitem__`` and ``__delitem__``
2683
Greg Ward40407942005-03-05 02:53:17 +00002684- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2685 correctly.
2686
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002687- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2688 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2689 character even if the user has passed a size parameter to get a proper
2690 line ending. Remove the special handling of a "\r\n" that has been split
2691 between two lines.
2692
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002693- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2694 about illegal code points. The codec now supports PEP 293 style error
2695 handlers.
2696
Walter Dörwald78a78b02005-09-01 12:04:29 +00002697- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002698 from the input stream, so that the output is a byte string in the correct
2699 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002700
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002701- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2702 considering it exactly like a '*'.
2703
Walter Dörwald007f8df2005-10-09 19:42:27 +00002704- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2705 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002706
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002707- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2708
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002709- Patch #1413711: Certain patterns of differences were making difflib
2710 touch the recursion limit.
2711
Walter Dörwald58917a62006-03-31 15:26:22 +00002712- Bug #947906: An object oriented interface has been added to the calendar
2713 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002714 called as a script (e.g. via ``python -mcalendar``). Localized month and
2715 weekday names can be ouput (even if an exotic encoding is used) using
2716 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002717
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002718Build
2719-----
2720
Neal Norwitz602d3392006-03-31 08:21:40 +00002721- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2722 by using -mieee gcc option.
2723

2725
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002726- Build support for Win64-AMD64 was added.
2727
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002728- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2729
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002730- Patch #881820: look for openpty and forkpty also in libbsd.
2731
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002732- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2733 The zlib module is now builtin on Windows.
2734
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002735- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2736
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002737- Bug #1189330: configure did not correctly determine the necessary
2738 value of LINKCC if python was built with GCC 4.0.
2739
Trent Mick8321b422005-07-26 02:29:21 +00002740- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2741 vulnerability in zlib 1.2.1 and 1.2.2.
2742
Brett Cannon08cd5982005-04-24 22:26:38 +00002743- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2744 flags that change binary compatibility. Changes were also made to
2745 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002746 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002747
Bob Ippolitoed233462005-03-29 13:47:59 +00002748- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2749 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2750 no longer exists). This configure patch makes things right.
2751
Martin v. Löwise2713be2005-03-08 15:03:08 +00002752- Bug #1158607: Build with --disable-unicode again.
2753
Brett Cannon46d96232005-02-16 00:07:19 +00002754- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2755 defined. Discovered as a result of not being able to build on OS X.
2756
Brett Cannon516592f2004-12-07 00:42:59 +00002757- setup.py now uses the directories specified in LDFLAGS using the -L option
2758 and in CPPFLAGS using the -I option for adding library and include
2759 directories, respectively, for compiling extension modules against. This has
2760 led to the core being compiled using the values in CPPFLAGS. It also removes
2761 the need for the special-casing of both DarwinPorts and Fink for darwin since
2762 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2763 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2764 Fink, ``-I/opt/local/include`` for DarwinPorts).
2765
Brett Cannon43802422005-02-10 20:48:03 +00002766- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2767 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2768 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2769 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002771C API
2772-----
2773
Tim Petersc9d78aa2006-03-26 23:27:58 +00002774- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2775 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2776 is obtained via the ``PyObject_`` family, it must be released via the
2777 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2778 always been officially true, but when Python's small-object allocator was
2779 introduced, an attempt was made to cater to a few extension modules
2780 discovered at the time that obtained memory via ``PyObject_New`` but
2781 released it via ``PyMem_DEL``. It's years later, and if such code still
2782 exists it will fail now (probably with segfaults, but calling wrong
2783 low-level memory management functions can yield many symptoms).
2784
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002785- Added a C API for set and frozenset objects.
2786
Raymond Hettinger66517482004-12-03 11:45:13 +00002787- Removed PyRange_New().
2788
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002789- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2790 mapping argument now. This string is used as a mapping table. Byte values
2791 greater than the length of the string and 0xFFFE are treated as undefined
2792 mappings.
