630-----------------
631
Neal Norwitz0bcafac2006-09-11 08:51:17 +0000632- Make _PyGILState_NoteThreadState() static, it was not used anywhere
633 outside of pystate.c and should not be necessary.
634
Brett Cannon19d76c52006-09-09 07:18:44 +0000635- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
636 allows calling unicode() on exceptions classes directly to succeed.
637
Georg Brandlecab6232006-09-06 06:47:02 +0000638- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000653- The return tuple from str.rpartition(sep) is (tail, sep, head) where
654 head is the original string if sep was not found.
655
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000656- Bug #1520864: unpacking singleton tuples in list comprehensions and
657 generator expressions (x for x, in ... ) works again. Fixing this problem
658 required changing the .pyc magic number. This means that .pyc files
659 generated before 2.5c2 will be regenerated.

773
Neal Norwitz24b6f202006-09-05 04:43:56 +0000774- Fix infinite recursion when subclassing long and overriding __hash__.
775
776- Fix concatenation (+=) of long strings.
777
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000778- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000779 compared equal or unequal to a string and a UnicodeDecodeError
780 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000781
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000782 Instead, the equal (==) and unequal (!=) comparison operators will
783 now issue a UnicodeWarning and interpret the two objects as
784 unequal. The UnicodeWarning can be filtered as desired using
785 the warning framework, e.g. silenced completely, turned into an
786 exception, logged, etc.
787
788 Note that compare operators other than equal and unequal will still
789 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000790
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000791- Fix segfault when doing string formatting on subclasses of long.
792
793- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
794 with new-style classes.
795
796- Fix bug related to __len__ functions returning negative values with
797 classic classes.
798
799- Patch #1538606, Fix __index__() clipping. There were some problems
800 discovered with the API and how integers that didn't fit into Py_ssize_t
801 were handled. This patch attempts to provide enough alternatives
802 to effectively use __index__.
803
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000804- Bug #1536021: __hash__ may now return long int; the final hash
805 value is obtained by invoking hash on the long int.
806
Thomas Hellerab1049c2006-08-08 17:37:00 +0000807- Bug #1536786: buffer comparison could emit a RuntimeWarning.

Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000809- Bug #1535165: fixed a segfault in input() and raw_input() when
810 sys.stdin is closed.
811
Thomas Heller74d36f02006-08-04 18:17:40 +0000812- On Windows, the PyErr_Warn function is now exported from
813 the Python dll again.
814
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000815- Bug #1191458: tracing over for loops now produces a line event
816 on each iteration. Fixing this problem required changing the .pyc
817 magic number. This means that .pyc files generated before 2.5c1
818 will be regenerated.
819
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000820- Bug #1333982: string/number constants were inappropriately stored
821 in the byte code and co_consts even if they were not used, ie
822 immediately popped off the stack.
823
Georg Brandle9462c72006-08-04 18:03:37 +0000824- Fixed a reference-counting problem in property().

828-------
829
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000830- Fix a bug in the ``compiler`` package that caused invalid code to be
831 generated for generator expressions.
832
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000833- The distutils version has been changed to 2.5.0. The change to
834 keep it programmatically in sync with the Python version running
835 the code (introduced in 2.5b3) has been reverted. It will continue
836 to be maintained manually as static string literal.
837
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000838- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000839 and this cannot be converted to the required C type, an exception is
840 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000841 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000842
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000843- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000844 an exception.
845
Tim Peterscbdd3502006-09-05 01:47:53 +0000846- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000847 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000848 workarounds for clocks with low resolution, to stop the code yielding
849 duplicate UUIDs.
850
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000851- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
852 before raising SystemExit, allowing IDLE to honor quit() and exit().
853
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000854- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.

Georg Brandl7a1af772006-08-14 21:55:28 +0000856- Patch #1536071: trace.py should now find the full module name of a
857 file correctly even on Windows.

Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000859- logging's atexit hook now runs even if the rest of the module has
860 already been cleaned up.

880
Thomas Heller1ce433e2006-08-14 16:20:04 +0000881- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
882 '-no-stack-protector' compiler flag for OpenBSD has been removed.
883
Thomas Heller86720042006-08-14 11:17:48 +0000884- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
885 uses the _as_parameter_ attribute when objects are passed to foreign
886 function calls. The ctypes version number was changed to 1.0.1.
887
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000888- Bug #1530559, struct.pack raises TypeError where it used to convert.

Fred Drake53912162006-07-29 13:22:49 +0000935What's New in Python 2.5 beta 3?
936================================
Neal Norwitza1f10902006-07-12 07:28:29 +0000937
Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000938*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000939
940Core and builtins
941-----------------
942
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000943- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000944 returned a long (see PEP 353).
945
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000946- Bug #1515471: string.replace() accepts character buffers again.
947
Neal Norwitz07aadb12006-07-30 06:55:48 +0000948- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
949 This provides the proper warning for struct.pack().
950 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
951
Neal Norwitz0d62a062006-07-30 06:53:31 +0000952- Patch #1531113: Fix augmented assignment with yield expressions.
953 Also fix a SystemError when trying to assign to yield expressions.
954
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000955- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
956 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
957 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
958 excessive filesystem operations during imports.
959
Tim Petersbc24eee2006-07-27 01:14:53 +0000960- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
961 operations on signed longs that are formally undefined by C.
962 Unfortunately, at least one compiler now cares about that, so complicated
963 the code to make that compiler happy again.
964
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000965- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
966
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000967- Patch #1232023: Stop including current directory in search
968 path on Windows.
969
Neal Norwitze1fdb322006-07-21 05:32:28 +0000970- Fix some potential crashes found with failmalloc.
971
Neal Norwitze7563102006-07-17 01:00:16 +0000972- Fix warnings reported by Klocwork's static analysis tool.
973
Neal Norwitz84be93b2006-07-16 01:50:38 +0000974- Bug #1512814, Fix incorrect lineno's when code within a function
975 had more than 255 blank lines.
976
Georg Brandl9dceedb2006-07-12 15:31:17 +0000977- Patch #1521179: Python now accepts the standard options ``--help`` and
978 ``--version`` as well as ``/?`` on Windows.
979
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000980- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000981 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000982 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000983
Tim Peters112aad32006-07-19 00:03:19 +0000984- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000985 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000986 new ``sys._current_frames()`` returns a dictionary with one entry,
987 mapping the faux "thread id" 0 to the current frame.
988
Ronald Oussoren3075e162006-07-25 20:28:55 +0000989- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000990

993-------
994
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000995- Correction of patch #1455898: In the mbcs decoder, set final=False
996 for stream decoder, but final=True for the decode function.
997
Georg Brandl07fec3a2006-08-01 18:49:24 +0000998- os.urandom no longer masks unrelated exceptions like SystemExit or
999 KeyboardInterrupt.
1000
Tim Peters4643c2f2006-08-10 22:45:34 +00001001- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001002 shutil.copytree on Windows
1003
Georg Brandle34ac7c2006-07-30 11:07:23 +00001004- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1005 refers to file descriptors, not file objects.
1006
Tim Peterscbdd3502006-09-05 01:47:53 +00001007- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001008 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001009 #1513611, and probably others.
1010
Georg Brandledd9b0d2006-07-29 09:33:26 +00001011- Bug #1441397: The compiler module now recognizes module and function
1012 docstrings correctly as it did in Python 2.4.
1013
Tim Peters6f681472006-07-27 23:44:37 +00001014- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1015 lost that tests are sorted by name before being run. This rarely
1016 matters for well-written tests, but can create baffling symptoms if
1017 side effects from one test to the next affect outcomes. ``DocTestFinder``
1018 has been changed to sort the list of tests it returns.
1019
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001020- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001021 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001022
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001023- Bug #978833: Really close underlying socket in _socketobject.close.
1024
Georg Brandldb232dc2006-08-20 13:15:43 +00001025- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1026 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001027
Georg Brandlcf0c1722006-07-26 07:23:32 +00001028- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1029 to recursive calls and call it with the failing package name.
1030
Martin v. Löwis0b483032006-07-25 09:53:12 +00001031- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1032
Georg Brandlc13c34c2006-07-24 14:09:56 +00001033- Patch #1515343: Fix printing of deprecated string exceptions with a
1034 value in the traceback module.
1035
Greg Ward48fae7a2006-07-23 16:05:51 +00001036- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1037
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001038- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1039
Brett Cannoncaebe222006-07-18 04:41:36 +00001040- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1041 argument tuple. For arguments where zero is illegal, the value is forced to
1042 the minimum value that is correct. This is to support an undocumented but
1043 common way people used to fill in inconsequential information in the time
1044 tuple pre-2.4.
1045
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001046- Patch #1220874: Update the binhex module for Mach-O.
1047
Barry Warsawb110bad2006-07-21 14:51:07 +00001048- The email package has improved RFC 2231 support, specifically for
1049 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1050 (name*0=<blah>) parameter continuations. This may change the types of
1051 values returned from email.message.Message.get_param() and friends.
1052 Specifically in some cases where non-encoded continuations were used,
1053 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1054 will just return the string (since non-encoded continuations don't have
1055 charset and language parts).
1056
1057 Also, whereas % values were decoded in all parameter continuations, they are
1058 now only decoded in encoded parameter parts.
1059
Ronald Oussoren3075e162006-07-25 20:28:55 +00001060- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1061
1062- Bug #1517996: IDLE now longer shows the default Tk menu when a
1063 path browser, class browser or debugger is the frontmost window on MacOS X
1064
Barry Warsaw00decd72006-07-27 23:43:15 +00001065- Patch #1520294: Support for getset and member descriptors in types.py,
1066 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1067 of an object against these built-in types and more importantly, for getting
1068 their docstrings printed in the interactive interpreter's help() function.

1072-----------------
1073
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001074- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1075 a socket operation on a socket with a timeout, the exception will be
1076 caught correctly. Previously, the exception was not caught.
1077
Thomas Heller1393d6a2006-07-28 21:43:20 +00001078- Patch #1529514: The _ctypes extension is now compiled on more
1079 openbsd target platforms.
1080
Tim Peters9cab5932006-07-28 00:30:00 +00001081- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1082 a memory leak, affecting pickles and deep copies.
1083
Tim Petersbc24eee2006-07-27 01:14:53 +00001084- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001085 Paul Eggert.
1086
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001087- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1088
Thomas Hellerce049a02006-07-14 17:51:14 +00001089- Patch #1521817: Index range checking on ctypes arrays containing
1090 exactly one element enabled again. This allows iterating over these
1091 arrays, without the need to check the array size before.
1092
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001093- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001094 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001095 /dev/null in certain cases; this is now fixed.
1096
Thomas Heller47d7a062006-07-12 08:43:47 +00001097- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1098 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001099
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001100- Because of a misspelled preprocessor symbol, ctypes was always
1101 compiled without thread support; this is now fixed.
1102
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001103- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1104 methods now allow their database parameter to be None as the
1105 sleepycat API allows.
1106
Matt Flemingec926502006-07-28 11:27:27 +00001107- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1108 bluetooth API compared with Linux and FreeBSD.
1109
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001110Tests
1111-----
1112
1113- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1114 how long the test file should take to play. Now accepts taking 2.93 secs
1115 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1116
Georg Brandl4793aa32006-07-28 18:31:39 +00001117- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1118 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1119 run via ``regrtest.py``. Now they do.

1128
1129- PythonLauncher now works correctly when the path to the script contains
1130 characters that are treated specially by the shell (such as quotes).
1131
1132- Bug #1527397: PythonLauncher now launches scripts with the working directory
1133 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001134 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001135 expect.

1145
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001146- Bug #1441486: The literal representation of -(sys.maxint - 1)
1147 again evaluates to a int object, not a long.
1148
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001149- Bug #1501934: The scope of global variables that are locally assigned
1150 using augmented assignment is now correctly determined.
1151
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001152- Bug #927248: Recursive method-wrapper objects can now safely
1153 be released.
1154
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001155- Bug #1417699: Reject locale-specific decimal point in float()
1156 and atof().
1157
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001158- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1159 omit a default "error" argument for NULL pointer. This allows
1160 the parser to take a codec from cjkcodecs again.

Neal Norwitzfb48afa2006-07-08 05:31:37 +00001162- Bug #1519018: 'as' is now validated properly in import statements.
1163
Neal Norwitz28746ab2006-07-09 22:14:42 +00001164- On 64 bit systems, int literals that use less than 64 bits are
1165 now ints rather than longs.
1166
Neal Norwitzed657552006-07-10 00:04:44 +00001167- Bug #1512814, Fix incorrect lineno's when code at module scope
1168 started after line 256.
1169
Tim Peters32a83612006-07-10 21:08:24 +00001170- New function ``sys._current_frames()`` returns a dict mapping thread
1171 id to topmost thread stack frame. This is for expert use, and is
1172 especially useful for debugging application deadlocks. The functionality
1173 was previously available in Fazal Majid's ``threadframe`` extension
1174 module, but it wasn't possible to do this in a wholly threadsafe way from
1175 an extension.

1184
Tim Peters32a83612006-07-10 21:08:24 +00001185- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001186 environment variable to be set in order to the SDK environment
1187 for finding the compiler, include files, etc.
1188
Martin v. Löwis388a8c22006-07-06 19:28:03 +00001189- Bug #1515998: Properly generate logical ids for files in bdist_msi.
1190
Nick Coghlan2d792252006-07-06 13:47:18 +00001191- warnings.py now ignores ImportWarning by default
1192
Thomas Woutersadd19112006-07-05 11:03:49 +00001193- string.Template() now correctly handles tuple-values. Previously,
1194 multi-value tuples would raise an exception and single-value tuples would
1195 be treated as the value they contain, instead.
1196
Martin v. Löwisede77f52006-07-03 13:01:35 +00001197- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1198 even if some data are received.
1199
Martin v. Löwis45482392006-07-03 12:28:58 +00001200- Bug #1267547: Put proper recursive setup.py call into the
1201 spec file generated by bdist_rpm.
1202
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001203- Bug #1514693: Update turtle's heading when switching between
1204 degrees and radians.
1205
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001206- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001207 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001208
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001209- Bug #1514703: Only setup canvas window in turtle when the canvas
1210 is created.
1211
Martin v. Löwis7596e832006-07-01 15:33:37 +00001212- Bug #1513223: .close() of a _socketobj now releases the underlying
1213 socket again, which then gets closed as it becomes unreferenced.
1214
Fred Drake10497c82006-06-29 02:57:48 +00001215- Bug #1504333: Make sgmllib support angle brackets in quoted
1216 attribute values.
1217
1218- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1219 sgmllib ('[' and ']' were not accepted).
1220
Georg Brandl1be63af2006-06-28 20:23:25 +00001221- Fix a bug in the turtle module's end_fill function.
1222
Brett Cannon53ab5b72006-06-22 16:49:14 +00001223- Bug #1510580: The 'warnings' module improperly required that a Warning
1224 category be either a types.ClassType and a subclass of Warning. The proper
1225 check is just that it is a subclass with Warning as the documentation states.
1226
Georg Brandlad29e632006-06-21 17:45:17 +00001227- The compiler module now correctly compiles the new try-except-finally
1228 statement (bug #1509132).
1229
Neal Norwitz60373cd2006-06-22 06:30:50 +00001230- The wsgiref package is now installed properly on Unix.
1231
Vinay Sajip28e57612006-07-01 10:45:20 +00001232- A bug was fixed in logging.config.fileConfig() which caused a crash on
1233 shutdown when fileConfig() was called multiple times.
1234
Gerhard Häring762fbd32006-07-02 17:48:30 +00001235- The sqlite3 module did cut off data from the SQLite database at the first
1236 null character before sending it to a custom converter. This has been fixed
1237 now.
1238
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001239Extension Modules
1240-----------------
1241
Tim Peters112aad32006-07-19 00:03:19 +00001242- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1243 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1244 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001245
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001246- Assigning None to pointer type fields in ctypes structures possible
1247 overwrote the wrong fields, this is fixed now.
1248
1249- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1250 on non-Windows platforms.
1251
1252- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1253 integer or long, without range checking.
1254
1255- Patch #1517790: It is now possible to use custom objects in the ctypes
1256 foreign function argtypes sequence as long as they provide a from_param
1257 method, no longer is it required that the object is a ctypes type.
1258
1259- The '_ctypes' extension module now works when Python is configured
1260 with the --without-threads option.
1261
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001262- Bug #1513646: os.access on Windows now correctly determines write
1263 access, again.
1264
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001265- Bug #1512695: cPickle.loads could crash if it was interrupted with
1266 a KeyboardInterrupt.
1267
Neal Norwitza12aa882006-07-06 06:45:08 +00001268- Bug #1296433: parsing XML with a non-default encoding and
1269 a CharacterDataHandler could crash the interpreter in pyexpat.
1270
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001271- Patch #1516912: improve Modules support for OpenVMS.
1272

1274-----
1275
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001276- Automate Windows build process for the Win64 SSL module.
1277
Tim Peters32a83612006-07-10 21:08:24 +00001278- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001279 Previously, the slight difference could cause compilation errors of the
1280 'zlib' module on systems with more than one version of zlib.
1281
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001282- The MSI compileall step was fixed to also support a TARGETDIR
1283 with spaces in it.
1284
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001285- Bug #1517388: sqlite3.dll is now installed on Windows independent
1286 of Tcl/Tk.
1287
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001288- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001289 trying to be installed even though it's empty.

1294- Call os.waitpid() at the end of tests that spawn child processes in order
1295 to minimize resources (zombies).
1296
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001297Documentation
1298-------------
1299
Nick Coghlan2d792252006-07-06 13:47:18 +00001300- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1301 documentation for the warnings module.
1302
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001303- Patch #1509163: MS Toolkit Compiler no longer available.
1304
Neal Norwitz56640df2006-07-10 02:36:41 +00001305- Patch #1504046: Add documentation for xml.etree.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001310
Anthony Baxterd1136802006-06-19 12:04:15 +00001311*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +00001312
1313Core and builtins
1314-----------------
1315
Georg Brandla56b9152006-06-19 06:35:54 +00001316- Patch #1507676: Error messages returned by invalid abstract object operations
1317 (such as iterating over an integer) have been improved and now include the
1318 type of the offending object to help with debugging.
1319
Brett Cannonea3912b2006-06-13 21:46:41 +00001320- Bug #992017: A classic class that defined a __coerce__() method that returned
1321 its arguments swapped would infinitely recurse and segfault the interpreter.
1322
Neal Norwitz909eb122006-06-12 02:13:21 +00001323- Fix the socket tests so they can be run concurrently.
1324
Neal Norwitzb9845e72006-06-12 02:11:18 +00001325- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001326 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001327
Brett Cannon22565aa2006-06-09 22:31:23 +00001328- Bug #532646: object.__call__() will continue looking for the __call__
1329 attribute on objects until one without one is found. This leads to recursion
1330 when you take a class and set its __call__ attribute to an instance of the
1331 class. Originally fixed for classic classes, but this fix is for new-style.
1332 Removes the infinite_rec_3 crasher.
1333
Georg Brandl24250812006-06-09 18:45:48 +00001334- The string and unicode methods startswith() and endswith() now accept
1335 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1336
Brett Cannonde3b0522006-06-08 17:00:45 +00001337- Buffer objects, at the C level, never used the char buffer
1338 implementation even when the char buffer for the wrapped object was
1339 explicitly requested (originally returned the read or write buffer).
1340 Now a TypeError is raised if the char buffer is not present but is
1341 requested.
1342
Georg Brandlddbaa662006-06-04 21:56:52 +00001343- Patch #1346214: Statements like "if 0: suite" are now again optimized
1344 away like they were in Python 2.4.
1345
Georg Brandlb7c8f542006-05-27 12:30:25 +00001346- Builtin exceptions are now full-blown new-style classes instead of
1347 instances pretending to be classes, which speeds up exception handling
1348 by about 80% in comparison to 2.5a2.
1349
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001350- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1351 Unicode 4.1.
1352
Georg Brandlf4ef1162006-05-26 18:03:31 +00001353- Patch #921466: sys.path_importer_cache is now used to cache valid and
1354 invalid file paths for the built-in import machinery which leads to
1355 fewer open calls on startup.
1356
Tim Peters696cf432006-05-24 21:10:40 +00001357- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1358 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1359 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1360 the number of input digits (it was and remains linear-time for bases
1361 2, 4, 8, 16 and 32).
1362
Tim Petersb713ec22006-05-23 18:45:30 +00001363- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1364 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1365 an integer close to ``sys.maxint``. This was repaired by patch
1366 #1335972, which also gives a nice speedup.
1367
Richard Jonescebbefc2006-05-23 18:28:17 +00001368- Patch #1337051: reduced size of frame objects.
1369
1370- PyErr_NewException now accepts a tuple of base classes as its
1371 "base" parameter.
1372
Richard Jones7c88dcc2006-05-23 10:37:38 +00001373- Patch #876206: function call speedup by retaining allocated frame
1374 objects.
1375
Georg Brandl7b90e162006-05-18 07:01:27 +00001376- Bug #1462152: file() now checks more thoroughly for invalid mode
1377 strings and removes a possible "U" before passing the mode to the
1378 C library function.
1379
Neal Norwitz1004a532006-05-15 07:17:23 +00001380- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1381
Neal Norwitz373f0a72006-05-15 07:04:36 +00001382- Bug #1487966: Fix SystemError with conditional expression in assignment
1383
Martin v. Löwis879768d2006-05-11 13:28:43 +00001384- WindowsError now has two error code attributes: errno, which carries
1385 the error values from errno.h, and winerror, which carries the error
1386 values from winerror.h. Previous versions put the winerror.h values
1387 (from GetLastError()) into the errno attribute.
1388
Martin v. Löwis77736712006-05-04 05:51:03 +00001389- Patch #1475845: Raise IndentationError for unexpected indent.
1390
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001391- Patch #1479181: split open() and file() from being aliases for each other.
1392
Tim Peters44bd9862006-06-01 13:49:23 +00001393- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1394 methods were always silently ignored by dictionaries when comparing keys.
1395 They are now passed through (except when using the C API function
1396 ``PyDict_GetItem()``, whose semantics did not change).
1397
1398- Bug #1456209: In some obscure cases it was possible for a class with a
1399 custom ``__eq__()`` method to confuse dict internals when class instances
1400 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1401 No, you don't have any code that did this ;-)

1409
Brett Cannon6ee7d012006-06-08 16:23:04 +00001410- Change binascii.hexlify to accept a read-only buffer instead of only a char
1411 buffer and actually follow its documentation.
1412
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001413- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1414
Nick Coghlanc649ec52006-05-29 12:43:05 +00001415- Patch #1478788 (modified version): The functional extension module has
1416 been renamed to _functools and a functools Python wrapper module added.
1417 This provides a home for additional function related utilities that are
1418 not specifically about functional programming. See PEP 309.
1419
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001420- Patch #1493701: performance enhancements for struct module.

1425 copy() method.
1426
Andrew MacIntyre92913322006-06-13 15:04:24 +00001427- Patch #1454481: thread stack size is now tunable at runtime for thread
1428 enabled builds on Windows and systems with Posix threads support.
1429
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001430- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1431 (up to the system limit of 32K characters).
1432
1433- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1434 As a result, these functions now raise WindowsError instead of OSError.
1435
Tim Peters7a822da2006-05-25 21:50:17 +00001436- ``time.clock()`` on Win64 should use the high-performance Windows
1437 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1438 Windows platforms).
1439
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001440- Calling Tk_Init twice is refused if the first call failed as that
1441 may deadlock.
1442
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001443- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1444 accept it without potentially using an uninitialized pointer.
1445
1446- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1447 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1448 patch numbers 1494885 and 1494902]

1455
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001456- bsddb: the __len__ method of a DB object has been fixed to return correct
1457 results. It could previously incorrectly return 0 in some cases.
1458 Fixes SF bug 1493322 (pybsddb bug 1184012).
1459
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001460- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1461 aborts the db transaction safely when a modifier callback fails.
1462 Fixes SF python patch/bug #1408584.
1463
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001464- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001465 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001466 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1467 database calls that would previously deadlock. [SF python bug #775414]
1468

1478 functions.
1479
Martin v. Löwis3798da02006-06-17 18:44:27 +00001480- Patch #812986: Update turtle output even if not tracing.
1481
Vinay Sajip28e57612006-07-01 10:45:20 +00001482- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001483 Tkinter.BaseWidget.
1484
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001485- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.

1488 classes.
1489
Georg Brandl83cc0d02006-06-14 08:50:03 +00001490- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1491 mime.types file for determining MIME types.
1492
Georg Brandl2605ca82006-06-14 06:08:31 +00001493- Bug #1339007: Shelf objects now don't raise an exception in their
1494 __del__ method when initialization failed.
1495
Martin v. Löwisd8251432006-06-14 05:21:04 +00001496- Patch #1455898: The MBCS codec now supports the incremental mode for
1497 double-byte encodings.
1498
Tim Peters43898b42006-06-14 04:09:25 +00001499- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1500 guarantee that adjacent triples in the return list always describe
1501 non-adjacent blocks. Previously, a pair of matching blocks could end
1502 up being described by multiple adjacent triples that formed a partition
1503 of the matching pair.
1504
Greg Ward0e0c9f42006-06-11 16:24:11 +00001505- Bug #1498146: fix optparse to handle Unicode strings in option help,
1506 description, and epilog.
1507
Greg Wardd1c797e2006-06-11 14:42:41 +00001508- Bug #1366250: minor optparse documentation error.
1509
Greg Ward7f547402006-06-11 00:40:49 +00001510- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1511 clarify docs.
1512
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001513- The wsgiref package has been added to the standard library.
1514
Nick Coghlan676725d2006-06-08 13:54:49 +00001515- The functions update_wrapper() and wraps() have been added to the functools
1516 module. These make it easier to copy relevant metadata from the original
1517 function when writing wrapper functions.
1518
Tim Petersd6a9eef2006-06-05 01:48:21 +00001519- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1520 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001521
Martin v. Löwis3f767792006-06-04 19:36:28 +00001522- Patch #1359618: Speed up charmap encoder by using a trie structure
1523 for lookup.
1524
Tim Petersd609b1a2006-06-02 23:22:51 +00001525- The functions in the ``pprint`` module now sort dictionaries by key
1526 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1527 if and only if its display required more than one line, although that
1528 wasn't documented. The new behavior increases predictability; e.g.,
1529 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1530
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001531- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1532 (thanks for J. J. Lee).
1533
Georg Brandl2b330372006-05-28 20:23:12 +00001534- Patch #1496206: improve urllib2 handling of passwords with respect to
1535 default HTTP and HTTPS ports.
1536
George Yoshidaf3c65de2006-05-28 16:39:09 +00001537- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1538
Bob Ippolito7298f272006-05-23 18:43:47 +00001539- Patch #1281707: speed up gzip.readline.
1540
Georg Brandlb89316f2006-05-17 15:51:16 +00001541- Patch #1180296: Two new functions were added to the locale module:
1542 format_string() to get the effect of "format % items" but locale-aware,
1543 and currency() to format a monetary number with currency sign.
1544
Georg Brandle3a25832006-05-17 14:56:04 +00001545- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1546 and several features added, such as speed and geometry control.
1547
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001548- Patch #1488881: add support for external file objects in bz2 compressed
1549 tarfiles.
1550
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001551- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1552 stdout arguments, making it possible to redirect input and output
1553 for remote debugging.
1554
1555- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1556 a couple of issues, notably handling of long file names using the
1557 GNU LONGNAME extension.
1558
1559- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1560 new flag when ``name`` is already the name of an option flag.
1561
1562- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1563 package.
1564
1565- Patch #1472854: make the rlcompleter.Completer class usable on non-
1566 UNIX platforms.
1567
1568- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1569
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001570- Bug #1472827: correctly escape newlines and tabs in attribute values in
1571 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001601What's New in Python 2.5 alpha 2?
1602=================================
1603
1604*Release date: 27-APR-2006*
1605
1606Core and builtins
1607-----------------
1608
Thomas Heller1b046642006-04-18 18:51:06 +00001609- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1610 by converting these apis from macros into exported functions again:
1611
1612 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1613 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1614 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1615 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1616 PyRun_String Py_CompileString
1617
Martin v. Löwis45294a92006-04-18 06:24:08 +00001618- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1619
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001620- All uses of PyStructSequence_InitType have been changed to initialize
1621 the type objects only once, even if the interpreter is initialized
1622 multiple times.
1623
Neal Norwitz61546162006-04-14 05:20:28 +00001624- Bug #1454485, array.array('u') could crash the interpreter. This was
1625 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1626 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1627
1628- Py_UNICODE is unsigned. It was always documented as unsigned, but
1629 due to a bug had a signed value in previous versions.
1630
Tim Peters3a5e8b12006-04-11 01:44:07 +00001631- Patch #837242: ``id()`` of any Python object always gives a positive
1632 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1633 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001634 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001635 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001636
Tim Peters3a5e8b12006-04-11 01:44:07 +00001637 def __hash__(self):
1638 return id(self) # WRONG
1639
1640 because a hash result must be a (short) Python int but it was always
1641 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001642 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001643 was always usable as a hash value before this patch. That's no longer
1644 necessarily so.
1645
1646- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001647 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001648 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001649 #1454844)
1650
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001651- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1652 involving generators that have paused outside of any ``try`` or ``with``
1653 blocks. (In 2.5a1, a paused generator that was part of a reference
1654 cycle could not be garbage collected, regardless of whether it was
1655 paused in a ``try`` or ``with`` block.)

1662
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001663- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1664 fails with an error condition.
1665
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001666- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1667
1668- Bug #1117761: bsddb.*open() no longer raises an exception when using
1669 the cachesize parameter.
1670
1671- Bug #1149413: bsddb.*open() no longer raises an exception when using
1672 a temporary db (file=None) with the 'n' flag to truncate on open.
1673
1674- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1675 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001676
Armin Rigoa9017c32006-04-19 11:50:27 +00001677- Patch #1062014: AF_UNIX sockets under Linux have a special

1684 of the process using the returncode attribute, instead of
1685 abusing errno.
1686
Tim Peters711bf302006-04-25 03:31:36 +00001687- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1688 a doctest to be skipped (the code is not run, and the expected output
1689 or exception is ignored).
1690
Nick Coghlanda2268f2006-04-24 04:37:15 +00001691- Fixed contextlib.nested to cope with exceptions being raised and
1692 caught inside exit handlers.
1693
Greg Wardab05edc2006-04-23 03:47:58 +00001694- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1695 hex, octal, or binary; add ``append_const`` action; keep going if
1696 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1697 added ``epilog`` for better help generation).
1698
Tim Peters21fbd572006-04-21 21:18:10 +00001699- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1700 called from a thread spawned as a side effect of importing a module.
1701
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001702- The pydoc module now supports documenting packages contained in
1703 .zip or .egg files.
1704
1705- The pkgutil module now has several new utility functions, such
1706 as ``walk_packages()`` to support working with packages that are either
1707 in the filesystem or zip files.
1708
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001709- The mailbox module can now modify and delete messages from
1710 mailboxes, in addition to simply reading them. Thanks to Gregory
1711 K. Johnson for writing the code, and to the 2005 Google Summer of
1712 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001713
Tim Petersc7605f22006-04-17 21:12:33 +00001714- The ``__del__`` method of class ``local`` in module ``_threading_local``
1715 returned before accomplishing any of its intended cleanup.
1716
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001717- Patch #790710: Add breakpoint command lists in pdb.

1722
Anthony Baxtere29002c2006-04-12 12:07:31 +00001723- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1724 Windows. Bug #1469163.
1725
Phillip J. Eby47032112006-04-11 01:07:43 +00001726- The warnings, linecache, inspect, traceback, site, and doctest modules
1727 were updated to work correctly with modules imported from zipfiles or
1728 via other PEP 302 __loader__ objects.
1729
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001730- Patch #1467770: Reduce usage of subprocess._active to processes which

1742
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001743- The Makefile now has a reindent target, which runs reindent.py on
1744 the library.
1745
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001746- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001749
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001750- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1751 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001752 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001753 CXX from --with-cxx-main, see description in README.
1754
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001755- Patch #1429775: Link extension modules with the shared libpython.
1756
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001757- Fixed a libffi build problem on MIPS systems.
1758
Tim Peters8931ff12006-05-13 23:28:20 +00001759- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1760 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1761 and "%zu" for unsigned integers of type ``size_t``.
1762
Anthony Baxter51bcb682006-04-05 14:51:42 +00001763Tests
1764-----
1765
Nick Coghlanda2268f2006-04-24 04:37:15 +00001766- test_contextlib now checks contextlib.nested can cope with exceptions
1767 being raised and caught inside exit handlers.
1768
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001769- test_cmd_line now checks operation of the -m and -c command switches
1770
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001771- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1772 it separately and by hand. It also wasn't cleaning up its changes to
1773 the current Decimal context.
1774
Thomas Woutersabd08882006-04-26 15:53:30 +00001775- regrtest.py now has a -M option to run tests that test the new limits of
1776 containers, on 64-bit architectures. Running these tests is only sensible
1777 on 64-bit machines with more than two gigabytes of memory. The argument

1787-------------
1788
Tim Petersb06d28c2006-05-12 01:57:59 +00001789- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1790
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001791- PEP 343: Added Context Types section to the library reference
1792 and attempted to bring other PEP 343 related documentation into
1793 line with the implementation and/or python-dev discussions.
1794
Tim Peters8dc73d22006-04-24 02:03:16 +00001795- Bug #1337990: clarified that ``doctest`` does not support examples
1796 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001804Core and builtins
1805-----------------
1806
Nick Coghlan43832302006-04-23 17:04:07 +00001807- PEP 338: -m command line switch now delegates to runpy.run_module
1808 allowing it to support modules in packages and zipfiles
1809
Martin v. Löwisc661b882006-04-20 04:54:23 +00001810- On Windows, .DLL is not an accepted file name extension for
1811 extension modules anymore; extensions are only found if they
1812 end in .PYD.
1813
Martin v. Löwisea62d252006-04-03 10:56:49 +00001814- Bug #1421664: sys.stderr.encoding is now set to the same value as
1815 sys.stdout.encoding.
1816
Neal Norwitz92e212f2006-04-03 04:48:37 +00001817- __import__ accepts keyword arguments.
1818
Georg Brandlccadf842006-03-31 18:54:53 +00001819- Patch #1460496: round() now accepts keyword arguments.
1820
Anthony Baxter262c00a2006-03-30 10:53:17 +00001821- Fixed bug #1459029 - unicode reprs were double-escaped.
1822
Hye-Shik Changd478f342006-03-23 12:32:36 +00001823- Patch #1396919: The system scope threads are reenabled on FreeBSD
1824 5.4 and later versions.
1825
Neal Norwitze98ccf62006-03-23 05:39:47 +00001826- Bug #1115379: Compiling a Unicode string with an encoding declaration
1827 now gives a SyntaxError.
1828
Georg Brandlabd1ff82006-03-18 07:59:59 +00001829- Previously, Python code had no easy way to access the contents of a
1830 cell object. Now, a ``cell_contents`` attribute has been added
1831 (closes patch #1170323).
1832
Tim Peterscf79aac2006-03-16 01:14:46 +00001833- Patch #1123430: Python's small-object allocator now returns an arena to
1834 the system ``free()`` when all memory within an arena becomes unused
1835 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1836 freed. Some applications will see a drop in virtual memory size now,
1837 especially long-running applications that, from time to time, temporarily
1838 use a large number of small objects. Note that when Python returns an
1839 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001840 platform C library will in turn return that memory to the operating system.
1841 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001842 appears to be effective at least on Microsoft C and gcc-based systems.
1843 Thanks to Evan Jones for hard work and patience.
1844
Georg Brandl533ff6f2006-03-08 18:09:27 +00001845- Patch #1434038: property() now uses the getter's docstring if there is
1846 no "doc" argument given. This makes it possible to legitimately use
1847 property() as a decorator to produce a read-only property.
1848
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001849- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1850 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1851 of requiring an int or long in slicing and a few other contexts, enabling
1852 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1853
Neal Norwitz995acdf2006-03-07 05:01:00 +00001854- Fixed various bugs reported by Coverity's Prevent tool.
1855
Brett Cannonbf364092006-03-01 04:25:17 +00001856- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1857 new exception base class, BaseException, which has a new message attribute.
1858 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1859 Raising a string exception now raises a DeprecationWarning.
1860
Thomas Woutersfb609f42006-02-28 16:37:25 +00001861- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1862 explicitly relative, using 'from .module import name' to mean 'from the same
1863 package as this module is in. Imports without dots still default to the
1864 old relative-then-absolute, unless 'from __future__ import
1865 absolute_import' is used.
1866
Brett Cannona7446e32006-02-27 23:39:10 +00001867- Properly check if 'warnings' raises an exception (usually when a filter set
1868 to "error" is triggered) when raising a warning for raising string
1869 exceptions.
1870
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001871- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001872 The name was removed from Include/code.h.
1873
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001874- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001875
Guido van Rossum1968ad32006-02-25 22:38:04 +00001876- Patch 1433928:
1877 - The copy module now "copies" function objects (as atomic objects).
1878 - dict.__getitem__ now looks for a __missing__ hook before raising
1879 KeyError.
1880
Tim Peters84ef21c2006-02-28 20:39:06 +00001881- PEP 343: with statement implemented. Needs ``from __future__ import
1882 with_statement``. Use of 'with' as a variable will generate a warning.
1883 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001884 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001885 The following objects have __context__ methods:
1886 - The built-in file type.
1887 - The thread.LockType type.
1888 - The following types defined by the threading module:
1889 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1890 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001891
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001892- Fix the encodings package codec search function to only search
1893 inside its own package. Fixes problem reported in patch #1433198.
1894
1895 Note: Codec packages should implement and register their own
1896 codec search function. PEP 100 has the details.
1897
Tim Peters9ea89d22006-06-04 03:26:02 +00001898- PEP 353: Using ``Py_ssize_t`` as the index type.
1899
1900- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1901 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1902 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1903 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1904 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001905
Neal Norwitzfc76d632006-01-10 06:03:13 +00001906- Patch #1400181, fix unicode string formatting to not use the locale.
1907 This is how string objects work. u'%f' could use , instead of .
1908 for the decimal point. Now both strings and unicode always use periods.
1909
Neal Norwitz671b9e32006-01-09 07:07:12 +00001910- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1911 configure would break checking curses.h.
1912
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001913- Bug #959576: The pwd module is now builtin. This allows Python to be
1914 built on UNIX platforms without $HOME set.
1915
Neal Norwitzc10978f2005-12-19 06:07:16 +00001916- Bug #1072182, fix some potential problems if characters are signed.
1917
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001918- Bug #889500, fix line number on SyntaxWarning for global declarations.
1919
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001920- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1921
Neal Norwitze7214a12005-12-18 05:03:17 +00001922- Support for converting hex strings to floats no longer works.
1923 This was not portable. float('0x3') now raises a ValueError.
1924
Barry Warsaw2a38a862005-12-18 01:27:35 +00001925- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001926 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001927 is now displayed in interactive prompt banner.
1928
Georg Brandlfa166682005-12-17 21:45:17 +00001929- Implementation of PEP 341 - Unification of try/except and try/finally.
1930 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001931 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001932
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001933- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1934 now encodes backslash correctly.
1935
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001936- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1937
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001938- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001939 and long longs.
1940
Neal Norwitz67715f02005-11-09 06:59:35 +00001941- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001942 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001943 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001944
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001945- Replaced most Unicode charmap codecs with new ones using the
1946 new Unicode translate string feature in the builtin charmap
1947 codec; the codecs were created from the mapping tables available
1948 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1949 encodings now include a mapping for the Apple logo)
1950
Tim Peterse3547fd2005-12-16 23:13:57 +00001951- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001952
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001953- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001954
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001955- A new AST parser implementation was completed. The abstract
1956 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001957 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001958
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001959- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001960 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1961
Neal Norwitz708e51a2005-10-03 04:48:15 +00001962- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1963
Neal Norwitz11bd1192005-10-03 00:54:56 +00001964- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1965 Provide a warning when a directory is passed on the command line.
1966
Neal Norwitz40d37812005-10-02 01:48:49 +00001967- Fix segfault with invalid coding.
1968
1969- SF bug #772896: unknown encoding results in MemoryError.
1970
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001971- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001972 supported a __len__() method which evaluated to False when the iterator
1973 was empty.
1974
Guido van Rossum630db602005-09-20 18:49:54 +00001975- On 64-bit platforms, when __len__() returns a value that cannot be
1976 represented as a C int, raise OverflowError.
1977
Skip Montanarof8948ca2005-09-19 03:54:46 +00001978- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001979 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001980
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001981- SF bug #893549: parsing keyword arguments was broken with a few format
1982 codes.
1983
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001984- Changes donated by Elemental Security to make it work on AIX 5.3
1985 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1986 bug #105470: test_pwd fails on 64bit system (Opteron).
1987
Guido van Rossum539c6622005-09-14 17:49:54 +00001988- Changes donated by Elemental Security to make it work on HP-UX 11 on
1989 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1990
Georg Brandl4550b8d2005-08-26 06:43:52 +00001991- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001992 (fixes bug #1119418).
1993
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001994- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1995
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001996- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1997 exceptions that cause a function to exit.
1998
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001999- The implementation of set() and frozenset() was revised to use its
2000 own internal data structure. Memory consumption is reduced by 1/3
2001 and there are modest speed-ups as well. The API is unchanged.
2002
Tim Petersde7990b2005-07-17 23:45:23 +00002003- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2004
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002005- SF bug #1229429: PyObject_CallMethod failed to decrement some
2006 reference counts in some error exit cases.
2007
Tim Petersecc6e6a2005-07-10 22:30:55 +00002008- SF bug #1185883: Python's small-object memory allocator took over
2009 a block managed by the platform C library whenever a realloc specified
2010 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002011 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002012 portable way to copy data from the C-managed block into Python's
2013 small-object space without risking a memory fault. Python's small-object
2014 realloc now leaves such blocks under the control of the platform C
2015 realloc.
2016
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002017- SF bug #1232517: An overflow error was not detected properly when
2018 attempting to convert a large float to an int in os.utime().
2019
Raymond Hettinger3296e692005-06-29 23:29:56 +00002020- SF bug #1224347: hex longs now print with lowercase letters just
2021 like their int counterparts.
2022
Michael W. Hudson188d4362005-06-20 16:52:57 +00002023- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2024 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2025 interpreter states; back out that fix and do a better job (see
2026 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2027 for a longer write-up of the problem).
2028
Michael W. Hudsondf888462005-06-03 14:41:55 +00002029- SF patch #1180995: marshal now uses a binary format by default when
2030 serializing floats.
2031
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002032- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2033 the routines that promise to produce IEEE 754 binary representations
2034 of floats now simply copy bytes around.
2035
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002036- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2037 278.
2038
Brett Cannonc3647ac2005-04-26 03:45:26 +00002039- patch #1109424: int, long, float, complex, and unicode now check for the
2040 proper magic slot for type conversions when subclassed. Previously the
2041 magic slot was ignored during conversion. Semantics now match the way
2042 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002043 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002044 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002045 Thanks Walter D�rwald.

Barry Warsawc8d907c2005-04-19 23:43:40 +00002047- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2048 NULL, now raise an AttributeError when attempting to set or delete the
2049 attribute. Previously a TypeError was raised, but this was inconsistent
2050 with the equivalent pure-Python implementation.
2051
Michael W. Hudson774479c2005-04-18 08:46:17 +00002052- It is now safe to call PyGILState_Release() before
2053 PyEval_InitThreads() (note that if there is reason to believe there
2054 are multiple threads around you still must call PyEval_InitThreads()
2055 before using the Python API; this fix is for extension modules that
2056 have no way of knowing if Python is multi-threaded yet).
2057
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002058- Typing Ctrl-C whilst raw_input() was waiting in a build with threads

2062 with im_class == im_self == NULL, which caused a crash when called.
2063
Tim Petersecc6e6a2005-07-10 22:30:55 +00002064- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002065 fixes the crash seen in bug #1165761
2066
Raymond Hettinger96229b12005-03-11 06:49:40 +00002067- Added two new builtins, any() and all().
2068
Brett Cannon409d8f22005-03-05 06:47:57 +00002069- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002070 (e.g., ``class C(): pass`` is no longer a syntax error).
2071 Patch #1176012 added support to the 'parser' module and 'compiler' package
2072 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002073

2077 returning None.
2078
Tim Petersecc6e6a2005-07-10 22:30:55 +00002079- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002080 ('\') with a specific error message.
2081
Martin v. Löwisff232d72005-03-03 09:24:38 +00002082- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2083
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002084- Bug #1124295: the __name__ attribute of file objects was
2085 inadvertently made inaccessible in restricted mode.
2086
Tim Petersecc6e6a2005-07-10 22:30:55 +00002087- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002088 an ferror() call.
2089
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002090- min() and max() now support key= arguments with the same meaning as in

2094 (2+3) --> (5).
2095
Raymond Hettingera422c342005-01-11 03:03:27 +00002096- set and frozenset objects can now be marshalled. SF #1098985.
2097
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002098- Bug #1077106: Poor argument checking could cause memory corruption
2099 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002100
Jeremy Hyltonab630502005-02-04 18:44:06 +00002101- The parser did not complain about future statements in illegal
2102 positions. It once again reports a syntax error if a future
2103 statement occurs after anything other than a doc string.
2104
Neil Schemenauercf52c072005-08-12 17:34:58 +00002105- Change the %s format specifier for str objects so that it returns a
2106 unicode instance if the argument is not an instance of basestring and
2107 calling __str__ on the argument returns a unicode instance.
2108
Tim Petersf4e69282006-02-27 17:15:31 +00002109- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2110 current thread state when the auto-GIL-state machinery knows about
2111 it (since the thread state is being deleted, continuing to remember it
2112 can't help, but can hurt if another thread happens to get created with
2113 the same thread id).

2144
Neal Norwitzb62c4332006-03-04 18:35:47 +00002145- The timing module is no longer built by default. It was deprecated

2314 flag to -1 (unknown) since it can't tell from the date whether it should
2315 be set.
2316
Fred Drakead5177c2006-04-01 22:14:43 +00002317- Patch #624325: urlparse.urlparse() and urlparse.urlsplit() results
2318 now sport attributes that provide access to the parts of the result.
2319
Georg Brandl7f6b67c2006-04-01 08:35:18 +00002320- Patch #1462498: sgmllib now handles entity and character references
2321 in attribute values.
2322
Anthony Baxterc51ee692006-04-01 00:57:31 +00002323- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002324 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002325 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002326 module will not be built.
2327
Tim Petersc17976e2006-04-01 00:26:53 +00002328- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2329 aren't officially supported here, and trying to use them will probably
2330 raise an exception some day. But dicts have been allowed, and "mostly
2331 worked", so support for them won't go away without warning.
2332
Georg Brandl338ef7d2006-03-31 18:42:16 +00002333- Bug #1445068: getpass.getpass() can now be given an explicit stream
2334 argument to specify where to write the prompt.
2335

2342 key to be used for signing the uploaded code.
2343
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002344- Queue.Queue objects now support .task_done() and .join() methods
2345 to make it easier to monitor when daemon threads have completed
2346 processing all enqueued tasks. Patch #1455676.
2347
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002348- popen2.Popen objects now preserve the command in a .cmd attribute.
2349
Thomas Hellerc61c0492006-03-22 10:09:27 +00002350- Added the ctypes ffi package.
2351
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002352- email 4.0 package now integrated. This is largely the same as the email 3.0
2353 package that was included in Python 2.3, except that PEP 8 module names are
2354 now used (e.g. mail.message instead of email.Message). The MIME classes
2355 have been moved to a subpackage (e.g. email.mime.text instead of
2356 email.MIMEText). The old names are still supported for now. Several
2357 deprecated Message methods have been removed and lots of bugs have been
2358 fixed. More details can be found in the email package documentation.
2359
Walter Dörwald40108c92006-03-27 08:15:44 +00002360- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2361 (a subclass of tuple) that provides incremental decoders and encoders
2362 (a way to use stateful codecs without the stream API). Python functions
2363 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2364 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2365 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002366
Walter Dörwald067db482006-03-15 22:17:27 +00002367- Patch #1359365: Calling next() on a closed StringIO.String object raises
2368 a ValueError instead of a StopIteration now (like file and cString.String do).
2369 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2370 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002371
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002372- A regrtest option -w was added to re-run failed tests in verbose mode.

2375 interpreter to exit.
2376
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002377- The function get_count() has been added to the gc module, and gc.collect()
2378 grew an optional 'generation' argument.
2379
Martin v. Löwisfbab90e2006-03-05 13:36:04 +00002380- A library msilib to generate Windows Installer files, and a distutils

2440 LoadError as documented, instead of IOError. For compatibility,
2441 LoadError subclasses IOError.
2442

Tim Peterse3547fd2005-12-16 23:13:57 +00002444 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2445 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2446 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2447 Ronald L. Rivest offered this advice for Python:
2448
2449 "The consensus of researchers in this area (at least as
2450 expressed at the NIST Hash Function Workshop 10/31/05),
2451 is that SHA-256 is a good choice for the time being, but
2452 that research should continue, and other alternatives may
2453 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002454
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002455- Added a subset of Fredrik Lundh's ElementTree package. Available

2508 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002509 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002510

2526 parameter, but uses the usual "kwargs=None".
2527
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002528- textwrap now processes text chunks at O(n) speed instead of O(n**2).

2549
Raymond Hettinger68c04532005-06-10 11:05:19 +00002550- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002551 roundtrip from lexed tokens back to Python source code. In addition,

2563 class at all.
2564
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002565- distutils.commands.upload was added to support uploading distribution

Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002576- Bug #1163325: Decimal infinities failed to hash. Attempting to
2577 hash a NaN raised an InvalidOperation instead of a TypeError.
2578
Tim Petersecc6e6a2005-07-10 22:30:55 +00002579- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002580 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2581
Martin v. Löwis00a73e72005-03-04 19:40:34 +00002582- Patch #1043890: Add extractall method to tarfile.
2583
Martin v. Löwisc72dd382005-03-04 13:50:17 +00002584- Patch #1075887: Don't require MSVC in distutils if there is nothing
2585 to build.
2586
Martin v. Löwis637431b2005-03-03 23:12:42 +00002587- Patch #1103407: Properly deal with tarfile iterators when untarring
2588 symbolic links on Windows.
2589

Martin v. Löwisa4dac402005-03-03 11:39:45 +00002591 profile.py if available.
2592
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00002593- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
2594
Martin v. Löwisc5574e82005-03-03 10:57:37 +00002595- Patch #1117454: Remove code to special-case cookies without values
2596 in LWPCookieJar.
2597
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00002598- Patch #1117339: Add cookielib special name tests.
2599

2605
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00002606- Patch #1104111: Alter setup.py --help and --help-commands.
2607
Martin v. Löwis4afe1542005-03-01 08:09:28 +00002608- Patch #1121234: Properly cleanup _exit and tkerror commands.
2609
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00002610- Patch #1049151: xdrlib now unpacks booleans as True or False.
2611
Raymond Hettingerbab41432005-02-05 01:31:19 +00002612- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2613
Guido van Rossumd0641422005-02-03 15:01:24 +00002614- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2615 disables recursive traversal through instance attributes, which can
2616 be exploited in various ways.
2617
Tim Peterse3547fd2005-12-16 23:13:57 +00002618- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002619 flags on the HTTP listening socket.
2620
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002621- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2622 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2623
Fred Drakefbdeaad2006-07-29 16:56:15 +00002624- Patches #893642, #1039083: add allow_none, encoding arguments to
2625 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002626
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002627- Bug #1110478: Revert os.environ.update to do putenv again.
2628
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002629- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2630
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002631- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2632
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002633- Enhancements to the csv module:
2634
2635 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002636 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002637 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002638 + Dialect parameter parsing has been re-implemented to improve error
2639 reporting.
2640 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2641 dictates.
2642 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002643 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002644 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002645 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2646 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002647 + reader now allows \r characters to be quoted (previously it only allowed
2648 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002649 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002650 + Dialect classes passed to the module are no longer instantiated by
2651 the module before being parsed (the former validation scheme required
2652 this, but the mechanism was unreliable).
2653 + The dialect registry now contains instances of the internal
2654 C-coded dialect type, rather than references to python objects.
2655 + the internal c-coded dialect type is now immutable.
2656 + register_dialect now accepts the same keyword dialect specifications
2657 as the reader and writer, allowing the user to register dialects
2658 without first creating a dialect class.
2659 + a configurable limit to the size of parsed fields has been added -
2660 previously, an unmatched quote character could result in the entire
2661 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002662 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002663 the parser field size limit (returning the former limit). The initial
2664 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002665 + A line_num attribute has been added to the reader object, which tracks
2666 the number of lines read from the source iterator. This is not
2667 the same as the number of records returned, as records can span
2668 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002669 + reader and writer objects were not being registered with the cyclic-GC.
2670 This has been fixed.
2671
Brett Cannone6539c42005-01-08 02:43:53 +00002672- _DummyThread objects in the threading module now delete self.__block that is
2673 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2674 lock primitives tend to be limited in number and thus should not be wasted on
2675 a _DummyThread object. Fixes bug #1089632.
2676
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002677- The imghdr module now detects Exif files.
2678
Raymond Hettinger6065d322004-12-20 23:51:53 +00002679- StringIO.truncate() now correctly adjusts the size attribute.
2680 (Bug #951915).
2681
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002682- locale.py now uses an updated locale alias table (built using
2683 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2684 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002685 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002686
Raymond Hettinger3557f422004-12-07 12:02:02 +00002687- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2688
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002689- the pickle module no longer accepts the deprecated None option in the
2690 args tuple returned by __reduce__().
2691
Brett Cannon84667c02004-12-07 03:25:18 +00002692- optparse now optionally imports gettext. This allows its use in setup.py.
2693
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002694- the pickle module no longer uses the deprecated bin parameter.
2695
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002696- the shelve module no longer uses the deprecated binary parameter.
2697
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002698- the pstats module no longer uses the deprecated ignore() method.
2699
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002700- the filecmp module no longer uses the deprecated use_statcache argument.
2701
Raymond Hettinger664347b2004-12-04 21:21:53 +00002702- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2703 extended or overridden by subclasses. Formerly, the subclassed method would
2704 be ignored by the rest of the module. (Bug #1078905).
2705
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002706- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002707 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002708
Walter Dörwald36733692004-12-22 12:50:50 +00002709- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2710 once when a size argument is given. This prevents a buffer overflow in the
2711 tokenizer with very long source lines.
2712
Barry Warsaw538561e2006-01-01 21:48:54 +00002713- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2714 immediately after creating the object, without any intervening
2715 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002716
Skip Montanaro05885812005-01-16 20:48:27 +00002717- The reconvert.quote function can now emit triple-quoted strings. The
2718 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002719
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002720- ``UserString.MutableString`` now supports negative indices in
2721 ``__setitem__`` and ``__delitem__``
2722
Greg Ward40407942005-03-05 02:53:17 +00002723- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2724 correctly.
2725
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002726- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2727 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2728 character even if the user has passed a size parameter to get a proper
2729 line ending. Remove the special handling of a "\r\n" that has been split
2730 between two lines.
2731
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002732- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2733 about illegal code points. The codec now supports PEP 293 style error
2734 handlers.
2735
Walter Dörwald78a78b02005-09-01 12:04:29 +00002736- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002737 from the input stream, so that the output is a byte string in the correct
2738 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002739
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002740- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2741 considering it exactly like a '*'.
2742
Walter Dörwald007f8df2005-10-09 19:42:27 +00002743- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2744 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002745
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002746- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2747
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002748- Patch #1413711: Certain patterns of differences were making difflib
2749 touch the recursion limit.
2750
Walter Dörwald58917a62006-03-31 15:26:22 +00002751- Bug #947906: An object oriented interface has been added to the calendar
2752 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002753 called as a script (e.g. via ``python -mcalendar``). Localized month and
2754 weekday names can be ouput (even if an exotic encoding is used) using
2755 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002756
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002757Build
2758-----
2759
Neal Norwitz602d3392006-03-31 08:21:40 +00002760- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2761 by using -mieee gcc option.
2762
Martin v. Löwis86d66262006-02-17 08:40:11 +00002763- Patch #1432345: Make python compile on DragonFly.
2764
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002765- Build support for Win64-AMD64 was added.
2766
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002767- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2768
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002769- Patch #881820: look for openpty and forkpty also in libbsd.
2770
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002771- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2772 The zlib module is now builtin on Windows.
2773
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002774- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2775
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002776- Bug #1189330: configure did not correctly determine the necessary
2777 value of LINKCC if python was built with GCC 4.0.
2778
Trent Mick8321b422005-07-26 02:29:21 +00002779- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2780 vulnerability in zlib 1.2.1 and 1.2.2.
2781
Brett Cannon08cd5982005-04-24 22:26:38 +00002782- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2783 flags that change binary compatibility. Changes were also made to
2784 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002785 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002786
Bob Ippolitoed233462005-03-29 13:47:59 +00002787- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2788 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2789 no longer exists). This configure patch makes things right.
2790
Martin v. Löwise2713be2005-03-08 15:03:08 +00002791- Bug #1158607: Build with --disable-unicode again.
2792
Brett Cannon46d96232005-02-16 00:07:19 +00002793- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2794 defined. Discovered as a result of not being able to build on OS X.
2795
Brett Cannon516592f2004-12-07 00:42:59 +00002796- setup.py now uses the directories specified in LDFLAGS using the -L option
2797 and in CPPFLAGS using the -I option for adding library and include
2798 directories, respectively, for compiling extension modules against. This has
2799 led to the core being compiled using the values in CPPFLAGS. It also removes
2800 the need for the special-casing of both DarwinPorts and Fink for darwin since
2801 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2802 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2803 Fink, ``-I/opt/local/include`` for DarwinPorts).
2804
Brett Cannon43802422005-02-10 20:48:03 +00002805- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2806 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2807 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2808 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002810C API
2811-----
2812
Tim Petersc9d78aa2006-03-26 23:27:58 +00002813- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2814 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2815 is obtained via the ``PyObject_`` family, it must be released via the
2816 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2817 always been officially true, but when Python's small-object allocator was
2818 introduced, an attempt was made to cater to a few extension modules
2819 discovered at the time that obtained memory via ``PyObject_New`` but
2820 released it via ``PyMem_DEL``. It's years later, and if such code still
2821 exists it will fail now (probably with segfaults, but calling wrong
2822 low-level memory management functions can yield many symptoms).
2823
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002824- Added a C API for set and frozenset objects.
2825
Raymond Hettinger66517482004-12-03 11:45:13 +00002826- Removed PyRange_New().
2827
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002828- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2829 mapping argument now. This string is used as a mapping table. Byte values
2830 greater than the length of the string and 0xFFFE are treated as undefined
2831 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002838
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002839- Patch #1276356: New resource "urlfetch" is implemented. This enables
