607-----------------
608
Neal Norwitz0bcafac2006-09-11 08:51:17 +0000609- Make _PyGILState_NoteThreadState() static, it was not used anywhere
610 outside of pystate.c and should not be necessary.
611
Brett Cannon19d76c52006-09-09 07:18:44 +0000612- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
613 allows calling unicode() on exceptions classes directly to succeed.
614
Georg Brandlecab6232006-09-06 06:47:02 +0000615- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
616 Also make sure that every exception class has __module__ set to
617 'exceptions'.
618
Georg Brandl37a9e572006-09-06 06:09:34 +0000619- Bug #1550983: emit better error messages for erroneous relative

621
Tim Peterscbdd3502006-09-05 01:47:53 +0000622- Overflow checking code in integer division ran afoul of new gcc
623 optimizations. Changed to be more standard-conforming.

629
Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000630- The return tuple from str.rpartition(sep) is (tail, sep, head) where
631 head is the original string if sep was not found.
632
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000633- Bug #1520864: unpacking singleton tuples in list comprehensions and
634 generator expressions (x for x, in ... ) works again. Fixing this problem
635 required changing the .pyc magic number. This means that .pyc files
636 generated before 2.5c2 will be regenerated.

748Core and builtins
749-----------------
750
Neal Norwitz24b6f202006-09-05 04:43:56 +0000751- Fix infinite recursion when subclassing long and overriding __hash__.
752
753- Fix concatenation (+=) of long strings.
754
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000755- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000756 compared equal or unequal to a string and a UnicodeDecodeError
757 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000758
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000759 Instead, the equal (==) and unequal (!=) comparison operators will
760 now issue a UnicodeWarning and interpret the two objects as
761 unequal. The UnicodeWarning can be filtered as desired using
762 the warning framework, e.g. silenced completely, turned into an
763 exception, logged, etc.
764
765 Note that compare operators other than equal and unequal will still
766 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000767
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000768- Fix segfault when doing string formatting on subclasses of long.
769
770- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
771 with new-style classes.
772
773- Fix bug related to __len__ functions returning negative values with
774 classic classes.
775
776- Patch #1538606, Fix __index__() clipping. There were some problems
777 discovered with the API and how integers that didn't fit into Py_ssize_t
778 were handled. This patch attempts to provide enough alternatives
779 to effectively use __index__.
780
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000781- Bug #1536021: __hash__ may now return long int; the final hash
782 value is obtained by invoking hash on the long int.
783
Thomas Hellerab1049c2006-08-08 17:37:00 +0000784- Bug #1536786: buffer comparison could emit a RuntimeWarning.
785
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000786- Bug #1535165: fixed a segfault in input() and raw_input() when
787 sys.stdin is closed.
788
Thomas Heller74d36f02006-08-04 18:17:40 +0000789- On Windows, the PyErr_Warn function is now exported from
790 the Python dll again.
791
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000792- Bug #1191458: tracing over for loops now produces a line event
793 on each iteration. Fixing this problem required changing the .pyc
794 magic number. This means that .pyc files generated before 2.5c1
795 will be regenerated.
796
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000797- Bug #1333982: string/number constants were inappropriately stored
798 in the byte code and co_consts even if they were not used, ie
799 immediately popped off the stack.
800
Georg Brandle9462c72006-08-04 18:03:37 +0000801- Fixed a reference-counting problem in property().

804Library
805-------
806
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000807- Fix a bug in the ``compiler`` package that caused invalid code to be
808 generated for generator expressions.
809
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000810- The distutils version has been changed to 2.5.0. The change to
811 keep it programmatically in sync with the Python version running
812 the code (introduced in 2.5b3) has been reverted. It will continue
813 to be maintained manually as static string literal.
814
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000815- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000816 and this cannot be converted to the required C type, an exception is
817 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000818 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000819
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000820- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000821 an exception.
822
Tim Peterscbdd3502006-09-05 01:47:53 +0000823- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000824 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000825 workarounds for clocks with low resolution, to stop the code yielding
826 duplicate UUIDs.
827
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000828- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
829 before raising SystemExit, allowing IDLE to honor quit() and exit().
830
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000831- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
832
Georg Brandl7a1af772006-08-14 21:55:28 +0000833- Patch #1536071: trace.py should now find the full module name of a
834 file correctly even on Windows.
835
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000836- logging's atexit hook now runs even if the rest of the module has
837 already been cleaned up.
838
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000839- Bug #1112549, fix DoS attack on cgi.FieldStorage.

Neal Norwitzff4b63b2006-08-04 04:50:21 +0000841- Bug #1531405, format_exception no longer raises an exception if
842 str(exception) raised an exception.
843
Neil Schemenauer06ded092006-08-04 16:20:30 +0000844- Fix a bug in the ``compiler`` package that caused invalid code to be
845 generated for nested functions.

856 raises the correct exceptions.
857
Thomas Heller1ce433e2006-08-14 16:20:04 +0000858- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
859 '-no-stack-protector' compiler flag for OpenBSD has been removed.
860
Thomas Heller86720042006-08-14 11:17:48 +0000861- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
862 uses the _as_parameter_ attribute when objects are passed to foreign
863 function calls. The ctypes version number was changed to 1.0.1.
864
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000865- Bug #1530559, struct.pack raises TypeError where it used to convert.
866 Passing float arguments to struct.pack when integers are expected
867 now triggers a DeprecationWarning.
868
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000869

Tim Peters4643c2f2006-08-10 22:45:34 +0000906- Bug #1069160. Internal correctness changes were made to
907 ``PyThreadState_SetAsyncExc()``. A test case was added, and
908 the documentation was changed to state that the return value
909 is always 1 (normal) or 0 (if the specified thread wasn't found).

Anthony Baxter5d32a9f2006-08-02 07:43:09 +0000915*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +0000916
917Core and builtins
918-----------------
919
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000920- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000921 returned a long (see PEP 353).
922
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000923- Bug #1515471: string.replace() accepts character buffers again.
924
Neal Norwitz07aadb12006-07-30 06:55:48 +0000925- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
926 This provides the proper warning for struct.pack().
927 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
928
Neal Norwitz0d62a062006-07-30 06:53:31 +0000929- Patch #1531113: Fix augmented assignment with yield expressions.
930 Also fix a SystemError when trying to assign to yield expressions.
931
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000932- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
933 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
934 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
935 excessive filesystem operations during imports.
936
Tim Petersbc24eee2006-07-27 01:14:53 +0000937- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
938 operations on signed longs that are formally undefined by C.
939 Unfortunately, at least one compiler now cares about that, so complicated
940 the code to make that compiler happy again.
941
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000942- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
943
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000944- Patch #1232023: Stop including current directory in search
945 path on Windows.
946
Neal Norwitze1fdb322006-07-21 05:32:28 +0000947- Fix some potential crashes found with failmalloc.
948
Neal Norwitze7563102006-07-17 01:00:16 +0000949- Fix warnings reported by Klocwork's static analysis tool.
950
Neal Norwitz84be93b2006-07-16 01:50:38 +0000951- Bug #1512814, Fix incorrect lineno's when code within a function
952 had more than 255 blank lines.
953
Georg Brandl9dceedb2006-07-12 15:31:17 +0000954- Patch #1521179: Python now accepts the standard options ``--help`` and
955 ``--version`` as well as ``/?`` on Windows.
956
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000957- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000958 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000959 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000960
Tim Peters112aad32006-07-19 00:03:19 +0000961- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000962 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000963 new ``sys._current_frames()`` returns a dictionary with one entry,
964 mapping the faux "thread id" 0 to the current frame.
965
Ronald Oussoren3075e162006-07-25 20:28:55 +0000966- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +0000967

970-------
971
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000972- Correction of patch #1455898: In the mbcs decoder, set final=False
973 for stream decoder, but final=True for the decode function.
974
Georg Brandl07fec3a2006-08-01 18:49:24 +0000975- os.urandom no longer masks unrelated exceptions like SystemExit or
976 KeyboardInterrupt.
977
Tim Peters4643c2f2006-08-10 22:45:34 +0000978- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +0000979 shutil.copytree on Windows
980
Georg Brandle34ac7c2006-07-30 11:07:23 +0000981- Bug #1002398: The documentation for os.path.sameopenfile now correctly
982 refers to file descriptors, not file objects.
983
Tim Peterscbdd3502006-09-05 01:47:53 +0000984- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000985 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +0000986 #1513611, and probably others.
987
Georg Brandledd9b0d2006-07-29 09:33:26 +0000988- Bug #1441397: The compiler module now recognizes module and function
989 docstrings correctly as it did in Python 2.4.
990
Tim Peters6f681472006-07-27 23:44:37 +0000991- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
992 lost that tests are sorted by name before being run. This rarely
993 matters for well-written tests, but can create baffling symptoms if
994 side effects from one test to the next affect outcomes. ``DocTestFinder``
995 has been changed to sort the list of tests it returns.
996
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000997- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +0000998 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +0000999
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001000- Bug #978833: Really close underlying socket in _socketobject.close.
1001
Georg Brandldb232dc2006-08-20 13:15:43 +00001002- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1003 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001004
Georg Brandlcf0c1722006-07-26 07:23:32 +00001005- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1006 to recursive calls and call it with the failing package name.
1007
Martin v. Löwis0b483032006-07-25 09:53:12 +00001008- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1009
Georg Brandlc13c34c2006-07-24 14:09:56 +00001010- Patch #1515343: Fix printing of deprecated string exceptions with a
1011 value in the traceback module.
1012
Greg Ward48fae7a2006-07-23 16:05:51 +00001013- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1014
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001015- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1016
Brett Cannoncaebe222006-07-18 04:41:36 +00001017- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1018 argument tuple. For arguments where zero is illegal, the value is forced to
1019 the minimum value that is correct. This is to support an undocumented but
1020 common way people used to fill in inconsequential information in the time
1021 tuple pre-2.4.
1022
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001023- Patch #1220874: Update the binhex module for Mach-O.
1024
Barry Warsawb110bad2006-07-21 14:51:07 +00001025- The email package has improved RFC 2231 support, specifically for
1026 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1027 (name*0=<blah>) parameter continuations. This may change the types of
1028 values returned from email.message.Message.get_param() and friends.
1029 Specifically in some cases where non-encoded continuations were used,
1030 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1031 will just return the string (since non-encoded continuations don't have
1032 charset and language parts).
1033
1034 Also, whereas % values were decoded in all parameter continuations, they are
1035 now only decoded in encoded parameter parts.
1036
Ronald Oussoren3075e162006-07-25 20:28:55 +00001037- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1038
1039- Bug #1517996: IDLE now longer shows the default Tk menu when a
1040 path browser, class browser or debugger is the frontmost window on MacOS X
1041
Barry Warsaw00decd72006-07-27 23:43:15 +00001042- Patch #1520294: Support for getset and member descriptors in types.py,
1043 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1044 of an object against these built-in types and more importantly, for getting
1045 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001048Extension Modules
1049-----------------
1050
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001051- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1052 a socket operation on a socket with a timeout, the exception will be
1053 caught correctly. Previously, the exception was not caught.
1054
Thomas Heller1393d6a2006-07-28 21:43:20 +00001055- Patch #1529514: The _ctypes extension is now compiled on more
1056 openbsd target platforms.
1057
Tim Peters9cab5932006-07-28 00:30:00 +00001058- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1059 a memory leak, affecting pickles and deep copies.
1060
Tim Petersbc24eee2006-07-27 01:14:53 +00001061- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001062 Paul Eggert.
1063
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001064- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1065
Thomas Hellerce049a02006-07-14 17:51:14 +00001066- Patch #1521817: Index range checking on ctypes arrays containing
1067 exactly one element enabled again. This allows iterating over these
1068 arrays, without the need to check the array size before.
1069
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001070- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001071 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001072 /dev/null in certain cases; this is now fixed.
1073
Thomas Heller47d7a062006-07-12 08:43:47 +00001074- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1075 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001076
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001077- Because of a misspelled preprocessor symbol, ctypes was always
1078 compiled without thread support; this is now fixed.
1079
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001080- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1081 methods now allow their database parameter to be None as the
1082 sleepycat API allows.
1083
Matt Flemingec926502006-07-28 11:27:27 +00001084- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1085 bluetooth API compared with Linux and FreeBSD.
1086
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001087Tests
1088-----
1089
1090- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1091 how long the test file should take to play. Now accepts taking 2.93 secs
1092 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1093
Georg Brandl4793aa32006-07-28 18:31:39 +00001094- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1095 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1096 run via ``regrtest.py``. Now they do.

1105
1106- PythonLauncher now works correctly when the path to the script contains
1107 characters that are treated specially by the shell (such as quotes).
1108
1109- Bug #1527397: PythonLauncher now launches scripts with the working directory
1110 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001111 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001112 expect.

1122
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001123- Bug #1441486: The literal representation of -(sys.maxint - 1)
1124 again evaluates to a int object, not a long.
1125
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001126- Bug #1501934: The scope of global variables that are locally assigned
1127 using augmented assignment is now correctly determined.
1128
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001129- Bug #927248: Recursive method-wrapper objects can now safely
1130 be released.
1131
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001132- Bug #1417699: Reject locale-specific decimal point in float()
1133 and atof().
1134
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001135- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1136 omit a default "error" argument for NULL pointer. This allows
1137 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001138
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001139- Bug #1519018: 'as' is now validated properly in import statements.
1140
Neal Norwitz28746ab2006-07-09 22:14:42 +00001141- On 64 bit systems, int literals that use less than 64 bits are
1142 now ints rather than longs.
1143
Neal Norwitzed657552006-07-10 00:04:44 +00001144- Bug #1512814, Fix incorrect lineno's when code at module scope
1145 started after line 256.
1146
Tim Peters32a83612006-07-10 21:08:24 +00001147- New function ``sys._current_frames()`` returns a dict mapping thread
1148 id to topmost thread stack frame. This is for expert use, and is
1149 especially useful for debugging application deadlocks. The functionality
1150 was previously available in Fazal Majid's ``threadframe`` extension
1151 module, but it wasn't possible to do this in a wholly threadsafe way from
1152 an extension.

1159
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001160- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1161
Tim Peters32a83612006-07-10 21:08:24 +00001162- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001163 environment variable to be set in order to the SDK environment

1169
Thomas Woutersadd19112006-07-05 11:03:49 +00001170- string.Template() now correctly handles tuple-values. Previously,
1171 multi-value tuples would raise an exception and single-value tuples would
1172 be treated as the value they contain, instead.
1173
Martin v. Löwisede77f52006-07-03 13:01:35 +00001174- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1179
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001180- Bug #1514693: Update turtle's heading when switching between

Martin v. Löwis2b88f632006-07-03 10:19:49 +00001184 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001185
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001186- Bug #1514703: Only setup canvas window in turtle when the canvas
1187 is created.
1188
Martin v. Löwis7596e832006-07-01 15:33:37 +00001189- Bug #1513223: .close() of a _socketobj now releases the underlying
1190 socket again, which then gets closed as it becomes unreferenced.
1191
Fred Drake10497c82006-06-29 02:57:48 +00001192- Bug #1504333: Make sgmllib support angle brackets in quoted
1193 attribute values.
1194
1195- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1196 sgmllib ('[' and ']' were not accepted).
1197
Georg Brandl1be63af2006-06-28 20:23:25 +00001198- Fix a bug in the turtle module's end_fill function.
1199
Brett Cannon53ab5b72006-06-22 16:49:14 +00001200- Bug #1510580: The 'warnings' module improperly required that a Warning
1201 category be either a types.ClassType and a subclass of Warning. The proper
1202 check is just that it is a subclass with Warning as the documentation states.
1203
Georg Brandlad29e632006-06-21 17:45:17 +00001204- The compiler module now correctly compiles the new try-except-finally
1205 statement (bug #1509132).
1206
Neal Norwitz60373cd2006-06-22 06:30:50 +00001207- The wsgiref package is now installed properly on Unix.
1208

1210 shutdown when fileConfig() was called multiple times.
1211
Gerhard Häring762fbd32006-07-02 17:48:30 +00001212- The sqlite3 module did cut off data from the SQLite database at the first
1213 null character before sending it to a custom converter. This has been fixed
1214 now.
1215
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001216Extension Modules
1217-----------------
1218
Tim Peters112aad32006-07-19 00:03:19 +00001219- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1220 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1221 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001222
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001223- Assigning None to pointer type fields in ctypes structures possible
1224 overwrote the wrong fields, this is fixed now.
1225
1226- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1227 on non-Windows platforms.
1228
1229- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1230 integer or long, without range checking.
1231
1232- Patch #1517790: It is now possible to use custom objects in the ctypes
1233 foreign function argtypes sequence as long as they provide a from_param
1234 method, no longer is it required that the object is a ctypes type.
1235
1236- The '_ctypes' extension module now works when Python is configured
1237 with the --without-threads option.
1238
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001239- Bug #1513646: os.access on Windows now correctly determines write
1240 access, again.
1241
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001242- Bug #1512695: cPickle.loads could crash if it was interrupted with
1243 a KeyboardInterrupt.
1244
Neal Norwitza12aa882006-07-06 06:45:08 +00001245- Bug #1296433: parsing XML with a non-default encoding and
1246 a CharacterDataHandler could crash the interpreter in pyexpat.
1247
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001248- Patch #1516912: improve Modules support for OpenVMS.

1252
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001253- Automate Windows build process for the Win64 SSL module.
1254
Tim Peters32a83612006-07-10 21:08:24 +00001255- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001256 Previously, the slight difference could cause compilation errors of the
1257 'zlib' module on systems with more than one version of zlib.
1258
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001259- The MSI compileall step was fixed to also support a TARGETDIR

Anthony Baxter51bcb682006-04-05 14:51:42 +00001289
1290Core and builtins
1291-----------------
1292
Georg Brandla56b9152006-06-19 06:35:54 +00001293- Patch #1507676: Error messages returned by invalid abstract object operations
1294 (such as iterating over an integer) have been improved and now include the
1295 type of the offending object to help with debugging.
1296
Brett Cannonea3912b2006-06-13 21:46:41 +00001297- Bug #992017: A classic class that defined a __coerce__() method that returned
1298 its arguments swapped would infinitely recurse and segfault the interpreter.
1299
Neal Norwitz909eb122006-06-12 02:13:21 +00001300- Fix the socket tests so they can be run concurrently.
1301
Neal Norwitzb9845e72006-06-12 02:11:18 +00001302- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001303 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001304
Brett Cannon22565aa2006-06-09 22:31:23 +00001305- Bug #532646: object.__call__() will continue looking for the __call__
1306 attribute on objects until one without one is found. This leads to recursion
1307 when you take a class and set its __call__ attribute to an instance of the
1308 class. Originally fixed for classic classes, but this fix is for new-style.
1309 Removes the infinite_rec_3 crasher.
1310
Georg Brandl24250812006-06-09 18:45:48 +00001311- The string and unicode methods startswith() and endswith() now accept
1312 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1313
Brett Cannonde3b0522006-06-08 17:00:45 +00001314- Buffer objects, at the C level, never used the char buffer
1315 implementation even when the char buffer for the wrapped object was
1316 explicitly requested (originally returned the read or write buffer).
1317 Now a TypeError is raised if the char buffer is not present but is
1318 requested.
1319
Georg Brandlddbaa662006-06-04 21:56:52 +00001320- Patch #1346214: Statements like "if 0: suite" are now again optimized
1321 away like they were in Python 2.4.
1322
Georg Brandlb7c8f542006-05-27 12:30:25 +00001323- Builtin exceptions are now full-blown new-style classes instead of
1324 instances pretending to be classes, which speeds up exception handling
1325 by about 80% in comparison to 2.5a2.
1326
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001327- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1328 Unicode 4.1.
1329
Georg Brandlf4ef1162006-05-26 18:03:31 +00001330- Patch #921466: sys.path_importer_cache is now used to cache valid and
1331 invalid file paths for the built-in import machinery which leads to
1332 fewer open calls on startup.
1333
Tim Peters696cf432006-05-24 21:10:40 +00001334- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1335 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1336 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1337 the number of input digits (it was and remains linear-time for bases
1338 2, 4, 8, 16 and 32).
1339
Tim Petersb713ec22006-05-23 18:45:30 +00001340- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1341 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1342 an integer close to ``sys.maxint``. This was repaired by patch
1343 #1335972, which also gives a nice speedup.
1344
Richard Jonescebbefc2006-05-23 18:28:17 +00001345- Patch #1337051: reduced size of frame objects.
1346
1347- PyErr_NewException now accepts a tuple of base classes as its
1348 "base" parameter.
1349
Richard Jones7c88dcc2006-05-23 10:37:38 +00001350- Patch #876206: function call speedup by retaining allocated frame
1351 objects.
1352
Georg Brandl7b90e162006-05-18 07:01:27 +00001353- Bug #1462152: file() now checks more thoroughly for invalid mode
1354 strings and removes a possible "U" before passing the mode to the
1355 C library function.
1356
Neal Norwitz1004a532006-05-15 07:17:23 +00001357- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1358
Neal Norwitz373f0a72006-05-15 07:04:36 +00001359- Bug #1487966: Fix SystemError with conditional expression in assignment
1360
Martin v. Löwis879768d2006-05-11 13:28:43 +00001361- WindowsError now has two error code attributes: errno, which carries
1362 the error values from errno.h, and winerror, which carries the error
1363 values from winerror.h. Previous versions put the winerror.h values
1364 (from GetLastError()) into the errno attribute.
1365
Martin v. Löwis77736712006-05-04 05:51:03 +00001366- Patch #1475845: Raise IndentationError for unexpected indent.
1367
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001368- Patch #1479181: split open() and file() from being aliases for each other.
1369
Tim Peters44bd9862006-06-01 13:49:23 +00001370- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1371 methods were always silently ignored by dictionaries when comparing keys.
1372 They are now passed through (except when using the C API function
1373 ``PyDict_GetItem()``, whose semantics did not change).
1374
1375- Bug #1456209: In some obscure cases it was possible for a class with a
1376 custom ``__eq__()`` method to confuse dict internals when class instances
1377 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1378 No, you don't have any code that did this ;-)

1386
Brett Cannon6ee7d012006-06-08 16:23:04 +00001387- Change binascii.hexlify to accept a read-only buffer instead of only a char
1388 buffer and actually follow its documentation.
1389
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001390- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1391
Nick Coghlanc649ec52006-05-29 12:43:05 +00001392- Patch #1478788 (modified version): The functional extension module has
1393 been renamed to _functools and a functools Python wrapper module added.
1394 This provides a home for additional function related utilities that are
1395 not specifically about functional programming. See PEP 309.
1396
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001397- Patch #1493701: performance enhancements for struct module.

1403
Andrew MacIntyre92913322006-06-13 15:04:24 +00001404- Patch #1454481: thread stack size is now tunable at runtime for thread
1405 enabled builds on Windows and systems with Posix threads support.
1406
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001407- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1408 (up to the system limit of 32K characters).
1409
1410- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1411 As a result, these functions now raise WindowsError instead of OSError.
1412
Tim Peters7a822da2006-05-25 21:50:17 +00001413- ``time.clock()`` on Win64 should use the high-performance Windows
1414 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1415 Windows platforms).
1416
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001417- Calling Tk_Init twice is refused if the first call failed as that
1418 may deadlock.
1419
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001420- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1421 accept it without potentially using an uninitialized pointer.
1422
1423- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1424 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1425 patch numbers 1494885 and 1494902]

1432
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001433- bsddb: the __len__ method of a DB object has been fixed to return correct
1434 results. It could previously incorrectly return 0 in some cases.
1435 Fixes SF bug 1493322 (pybsddb bug 1184012).
1436
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001437- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1438 aborts the db transaction safely when a modifier callback fails.
1439 Fixes SF python patch/bug #1408584.
1440
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001441- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001442 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001443 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1444 database calls that would previously deadlock. [SF python bug #775414]
1445

Martin v. Löwisd8251432006-06-14 05:21:04 +00001473- Patch #1455898: The MBCS codec now supports the incremental mode for
1474 double-byte encodings.
1475
Tim Peters43898b42006-06-14 04:09:25 +00001476- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1477 guarantee that adjacent triples in the return list always describe
1478 non-adjacent blocks. Previously, a pair of matching blocks could end
1479 up being described by multiple adjacent triples that formed a partition
1480 of the matching pair.
1481
Greg Ward0e0c9f42006-06-11 16:24:11 +00001482- Bug #1498146: fix optparse to handle Unicode strings in option help,
1483 description, and epilog.
1484
Greg Wardd1c797e2006-06-11 14:42:41 +00001485- Bug #1366250: minor optparse documentation error.
1486
Greg Ward7f547402006-06-11 00:40:49 +00001487- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1488 clarify docs.
1489
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001490- The wsgiref package has been added to the standard library.
1491
Nick Coghlan676725d2006-06-08 13:54:49 +00001492- The functions update_wrapper() and wraps() have been added to the functools
1493 module. These make it easier to copy relevant metadata from the original
1494 function when writing wrapper functions.
1495
Tim Petersd6a9eef2006-06-05 01:48:21 +00001496- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1497 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001498
Martin v. Löwis3f767792006-06-04 19:36:28 +00001499- Patch #1359618: Speed up charmap encoder by using a trie structure
1500 for lookup.
1501
Tim Petersd609b1a2006-06-02 23:22:51 +00001502- The functions in the ``pprint`` module now sort dictionaries by key
1503 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1504 if and only if its display required more than one line, although that
1505 wasn't documented. The new behavior increases predictability; e.g.,
1506 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1507
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001508- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1509 (thanks for J. J. Lee).
1510
Georg Brandl2b330372006-05-28 20:23:12 +00001511- Patch #1496206: improve urllib2 handling of passwords with respect to
1512 default HTTP and HTTPS ports.
1513
George Yoshidaf3c65de2006-05-28 16:39:09 +00001514- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1515
Bob Ippolito7298f272006-05-23 18:43:47 +00001516- Patch #1281707: speed up gzip.readline.
1517
Georg Brandlb89316f2006-05-17 15:51:16 +00001518- Patch #1180296: Two new functions were added to the locale module:
1519 format_string() to get the effect of "format % items" but locale-aware,
1520 and currency() to format a monetary number with currency sign.
1521
Georg Brandle3a25832006-05-17 14:56:04 +00001522- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1523 and several features added, such as speed and geometry control.
1524
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001525- Patch #1488881: add support for external file objects in bz2 compressed
1526 tarfiles.
1527
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001528- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1529 stdout arguments, making it possible to redirect input and output
1530 for remote debugging.
1531
1532- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1533 a couple of issues, notably handling of long file names using the
1534 GNU LONGNAME extension.
1535
1536- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1537 new flag when ``name`` is already the name of an option flag.
1538
1539- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1540 package.
1541
1542- Patch #1472854: make the rlcompleter.Completer class usable on non-
1543 UNIX platforms.
1544
1545- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1546
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001547- Bug #1472827: correctly escape newlines and tabs in attribute values in
1548 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001578What's New in Python 2.5 alpha 2?
1579=================================
1580
1581*Release date: 27-APR-2006*
1582
1583Core and builtins
1584-----------------
1585
Thomas Heller1b046642006-04-18 18:51:06 +00001586- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1587 by converting these apis from macros into exported functions again:
1588
1589 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1590 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1591 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1592 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1593 PyRun_String Py_CompileString
1594
Martin v. Löwis45294a92006-04-18 06:24:08 +00001595- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1596
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001597- All uses of PyStructSequence_InitType have been changed to initialize
1598 the type objects only once, even if the interpreter is initialized
1599 multiple times.
1600
Neal Norwitz61546162006-04-14 05:20:28 +00001601- Bug #1454485, array.array('u') could crash the interpreter. This was
1602 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1603 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1604
1605- Py_UNICODE is unsigned. It was always documented as unsigned, but
1606 due to a bug had a signed value in previous versions.
1607
Tim Peters3a5e8b12006-04-11 01:44:07 +00001608- Patch #837242: ``id()`` of any Python object always gives a positive
1609 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1610 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001611 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001612 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001613
Tim Peters3a5e8b12006-04-11 01:44:07 +00001614 def __hash__(self):
1615 return id(self) # WRONG
1616
1617 because a hash result must be a (short) Python int but it was always
1618 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001619 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001620 was always usable as a hash value before this patch. That's no longer
1621 necessarily so.
1622
1623- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001624 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001625 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001626 #1454844)
1627
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001628- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1629 involving generators that have paused outside of any ``try`` or ``with``
1630 blocks. (In 2.5a1, a paused generator that was part of a reference
1631 cycle could not be garbage collected, regardless of whether it was
1632 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001633
Anthony Baxter51bcb682006-04-05 14:51:42 +00001634Extension Modules

1636
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001637- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1638 is a macro.
1639
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001640- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1641 fails with an error condition.
1642
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001643- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1644
1645- Bug #1117761: bsddb.*open() no longer raises an exception when using
1646 the cachesize parameter.
1647
1648- Bug #1149413: bsddb.*open() no longer raises an exception when using
1649 a temporary db (file=None) with the 'n' flag to truncate on open.
1650
1651- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1652 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001653
Armin Rigoa9017c32006-04-19 11:50:27 +00001654- Patch #1062014: AF_UNIX sockets under Linux have a special
1655 abstract namespace that is now fully supported.

Peter Astrand7d1d4362006-07-14 14:04:45 +00001660- Bug #1223937: subprocess.CalledProcessError reports the exit status
1661 of the process using the returncode attribute, instead of
1662 abusing errno.
1663
Tim Peters711bf302006-04-25 03:31:36 +00001664- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1665 a doctest to be skipped (the code is not run, and the expected output
1666 or exception is ignored).
1667
Nick Coghlanda2268f2006-04-24 04:37:15 +00001668- Fixed contextlib.nested to cope with exceptions being raised and
1669 caught inside exit handlers.
1670
Greg Wardab05edc2006-04-23 03:47:58 +00001671- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1672 hex, octal, or binary; add ``append_const`` action; keep going if
1673 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1674 added ``epilog`` for better help generation).
1675
Tim Peters21fbd572006-04-21 21:18:10 +00001676- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1677 called from a thread spawned as a side effect of importing a module.
1678
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001679- The pydoc module now supports documenting packages contained in
1680 .zip or .egg files.
1681
1682- The pkgutil module now has several new utility functions, such
1683 as ``walk_packages()`` to support working with packages that are either
1684 in the filesystem or zip files.
1685
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001686- The mailbox module can now modify and delete messages from
1687 mailboxes, in addition to simply reading them. Thanks to Gregory
1688 K. Johnson for writing the code, and to the 2005 Google Summer of
1689 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001690
Tim Petersc7605f22006-04-17 21:12:33 +00001691- The ``__del__`` method of class ``local`` in module ``_threading_local``
1692 returned before accomplishing any of its intended cleanup.
1693
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001694- Patch #790710: Add breakpoint command lists in pdb.
1695
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001696- Patch #1063914: Add Tkinter.Misc.clipboard_get().

1699
Anthony Baxtere29002c2006-04-12 12:07:31 +00001700- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1701 Windows. Bug #1469163.
1702
Phillip J. Eby47032112006-04-11 01:07:43 +00001703- The warnings, linecache, inspect, traceback, site, and doctest modules
1704 were updated to work correctly with modules imported from zipfiles or
1705 via other PEP 302 __loader__ objects.
1706
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001707- Patch #1467770: Reduce usage of subprocess._active to processes which
1708 the application hasn't waited on.

1719
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001720- The Makefile now has a reindent target, which runs reindent.py on
1721 the library.
1722
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001723- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis0f48d982006-04-14 14:34:26 +00001727- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1728 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001729 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001730 CXX from --with-cxx-main, see description in README.
1731

1735
Tim Peters8931ff12006-05-13 23:28:20 +00001736- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1737 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1738 and "%zu" for unsigned integers of type ``size_t``.
1739
Anthony Baxter51bcb682006-04-05 14:51:42 +00001740Tests
1741-----
1742
Nick Coghlanda2268f2006-04-24 04:37:15 +00001743- test_contextlib now checks contextlib.nested can cope with exceptions
1744 being raised and caught inside exit handlers.
1745
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001746- test_cmd_line now checks operation of the -m and -c command switches
1747
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001748- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1749 it separately and by hand. It also wasn't cleaning up its changes to
1750 the current Decimal context.
1751
Thomas Woutersabd08882006-04-26 15:53:30 +00001752- regrtest.py now has a -M option to run tests that test the new limits of
1753 containers, on 64-bit architectures. Running these tests is only sensible
1754 on 64-bit machines with more than two gigabytes of memory. The argument
1755 passed is the maximum amount of memory for the tests to use.

Nick Coghlanc195d8a2006-04-24 03:04:43 +00001768- PEP 343: Added Context Types section to the library reference
1769 and attempted to bring other PEP 343 related documentation into
1770 line with the implementation and/or python-dev discussions.
1771
Tim Peters8dc73d22006-04-24 02:03:16 +00001772- Bug #1337990: clarified that ``doctest`` does not support examples

1785 allowing it to support modules in packages and zipfiles
1786
Martin v. Löwisc661b882006-04-20 04:54:23 +00001787- On Windows, .DLL is not an accepted file name extension for
1788 extension modules anymore; extensions are only found if they
1789 end in .PYD.
1790
Martin v. Löwisea62d252006-04-03 10:56:49 +00001791- Bug #1421664: sys.stderr.encoding is now set to the same value as
1792 sys.stdout.encoding.
1793
Neal Norwitz92e212f2006-04-03 04:48:37 +00001794- __import__ accepts keyword arguments.
1795
Georg Brandlccadf842006-03-31 18:54:53 +00001796- Patch #1460496: round() now accepts keyword arguments.
1797
Anthony Baxter262c00a2006-03-30 10:53:17 +00001798- Fixed bug #1459029 - unicode reprs were double-escaped.
1799
Hye-Shik Changd478f342006-03-23 12:32:36 +00001800- Patch #1396919: The system scope threads are reenabled on FreeBSD
1801 5.4 and later versions.
1802
Neal Norwitze98ccf62006-03-23 05:39:47 +00001803- Bug #1115379: Compiling a Unicode string with an encoding declaration
1804 now gives a SyntaxError.
1805
Georg Brandlabd1ff82006-03-18 07:59:59 +00001806- Previously, Python code had no easy way to access the contents of a
1807 cell object. Now, a ``cell_contents`` attribute has been added
1808 (closes patch #1170323).
1809
Tim Peterscf79aac2006-03-16 01:14:46 +00001810- Patch #1123430: Python's small-object allocator now returns an arena to
1811 the system ``free()`` when all memory within an arena becomes unused
1812 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1813 freed. Some applications will see a drop in virtual memory size now,
1814 especially long-running applications that, from time to time, temporarily
1815 use a large number of small objects. Note that when Python returns an
1816 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001817 platform C library will in turn return that memory to the operating system.
1818 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001819 appears to be effective at least on Microsoft C and gcc-based systems.
1820 Thanks to Evan Jones for hard work and patience.
1821
Georg Brandl533ff6f2006-03-08 18:09:27 +00001822- Patch #1434038: property() now uses the getter's docstring if there is
1823 no "doc" argument given. This makes it possible to legitimately use
1824 property() as a decorator to produce a read-only property.
1825
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001826- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1827 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1828 of requiring an int or long in slicing and a few other contexts, enabling
1829 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1830
Neal Norwitz995acdf2006-03-07 05:01:00 +00001831- Fixed various bugs reported by Coverity's Prevent tool.
1832
Brett Cannonbf364092006-03-01 04:25:17 +00001833- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1834 new exception base class, BaseException, which has a new message attribute.
1835 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1836 Raising a string exception now raises a DeprecationWarning.
1837
Thomas Woutersfb609f42006-02-28 16:37:25 +00001838- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1839 explicitly relative, using 'from .module import name' to mean 'from the same
1840 package as this module is in. Imports without dots still default to the
1841 old relative-then-absolute, unless 'from __future__ import
1842 absolute_import' is used.
1843
Brett Cannona7446e32006-02-27 23:39:10 +00001844- Properly check if 'warnings' raises an exception (usually when a filter set
1845 to "error" is triggered) when raising a warning for raising string
1846 exceptions.
1847
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001848- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001849 The name was removed from Include/code.h.
1850
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001851- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001852
Guido van Rossum1968ad32006-02-25 22:38:04 +00001853- Patch 1433928:
1854 - The copy module now "copies" function objects (as atomic objects).
1855 - dict.__getitem__ now looks for a __missing__ hook before raising
1856 KeyError.
1857
Tim Peters84ef21c2006-02-28 20:39:06 +00001858- PEP 343: with statement implemented. Needs ``from __future__ import
1859 with_statement``. Use of 'with' as a variable will generate a warning.
1860 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001861 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001862 The following objects have __context__ methods:
1863 - The built-in file type.
1864 - The thread.LockType type.
1865 - The following types defined by the threading module:
1866 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1867 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001868
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001869- Fix the encodings package codec search function to only search
1870 inside its own package. Fixes problem reported in patch #1433198.
1871
1872 Note: Codec packages should implement and register their own
1873 codec search function. PEP 100 has the details.
1874
Tim Peters9ea89d22006-06-04 03:26:02 +00001875- PEP 353: Using ``Py_ssize_t`` as the index type.
1876
1877- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1878 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1879 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1880 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1881 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001882
Neal Norwitzfc76d632006-01-10 06:03:13 +00001883- Patch #1400181, fix unicode string formatting to not use the locale.
1884 This is how string objects work. u'%f' could use , instead of .
1885 for the decimal point. Now both strings and unicode always use periods.
1886
Neal Norwitz671b9e32006-01-09 07:07:12 +00001887- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1888 configure would break checking curses.h.
1889
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001890- Bug #959576: The pwd module is now builtin. This allows Python to be
1891 built on UNIX platforms without $HOME set.
1892
Neal Norwitzc10978f2005-12-19 06:07:16 +00001893- Bug #1072182, fix some potential problems if characters are signed.
1894
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001895- Bug #889500, fix line number on SyntaxWarning for global declarations.
1896
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001897- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1898
Neal Norwitze7214a12005-12-18 05:03:17 +00001899- Support for converting hex strings to floats no longer works.
1900 This was not portable. float('0x3') now raises a ValueError.
1901
Barry Warsaw2a38a862005-12-18 01:27:35 +00001902- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001903 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001904 is now displayed in interactive prompt banner.
1905
Georg Brandlfa166682005-12-17 21:45:17 +00001906- Implementation of PEP 341 - Unification of try/except and try/finally.
1907 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001908 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001909
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001910- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1911 now encodes backslash correctly.
1912
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001913- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1914
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001915- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001916 and long longs.
1917
Neal Norwitz67715f02005-11-09 06:59:35 +00001918- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001919 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001920 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001921
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001922- Replaced most Unicode charmap codecs with new ones using the
1923 new Unicode translate string feature in the builtin charmap
1924 codec; the codecs were created from the mapping tables available
1925 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1926 encodings now include a mapping for the Apple logo)
1927
Tim Peterse3547fd2005-12-16 23:13:57 +00001928- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001929
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001930- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001931
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001932- A new AST parser implementation was completed. The abstract
1933 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001934 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001935
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001936- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001937 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1938
Neal Norwitz708e51a2005-10-03 04:48:15 +00001939- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1940
Neal Norwitz11bd1192005-10-03 00:54:56 +00001941- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1942 Provide a warning when a directory is passed on the command line.
1943
Neal Norwitz40d37812005-10-02 01:48:49 +00001944- Fix segfault with invalid coding.
1945
1946- SF bug #772896: unknown encoding results in MemoryError.
1947
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001948- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001949 supported a __len__() method which evaluated to False when the iterator
1950 was empty.
1951
Guido van Rossum630db602005-09-20 18:49:54 +00001952- On 64-bit platforms, when __len__() returns a value that cannot be
1953 represented as a C int, raise OverflowError.
1954
Skip Montanarof8948ca2005-09-19 03:54:46 +00001955- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001956 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001957
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001958- SF bug #893549: parsing keyword arguments was broken with a few format
1959 codes.
1960
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001961- Changes donated by Elemental Security to make it work on AIX 5.3
1962 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1963 bug #105470: test_pwd fails on 64bit system (Opteron).
1964
Guido van Rossum539c6622005-09-14 17:49:54 +00001965- Changes donated by Elemental Security to make it work on HP-UX 11 on
1966 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1967
Georg Brandl4550b8d2005-08-26 06:43:52 +00001968- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001969 (fixes bug #1119418).
1970
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001971- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1972
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001973- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1974 exceptions that cause a function to exit.
1975
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001976- The implementation of set() and frozenset() was revised to use its
1977 own internal data structure. Memory consumption is reduced by 1/3
1978 and there are modest speed-ups as well. The API is unchanged.
1979
Tim Petersde7990b2005-07-17 23:45:23 +00001980- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
1981
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00001982- SF bug #1229429: PyObject_CallMethod failed to decrement some
1983 reference counts in some error exit cases.
1984
Tim Petersecc6e6a2005-07-10 22:30:55 +00001985- SF bug #1185883: Python's small-object memory allocator took over
1986 a block managed by the platform C library whenever a realloc specified
1987 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001988 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00001989 portable way to copy data from the C-managed block into Python's
1990 small-object space without risking a memory fault. Python's small-object
1991 realloc now leaves such blocks under the control of the platform C
1992 realloc.
1993
Michael W. Hudsonb8963812005-07-05 15:21:58 +00001994- SF bug #1232517: An overflow error was not detected properly when
1995 attempting to convert a large float to an int in os.utime().
1996
Raymond Hettinger3296e692005-06-29 23:29:56 +00001997- SF bug #1224347: hex longs now print with lowercase letters just
1998 like their int counterparts.
1999
Michael W. Hudson188d4362005-06-20 16:52:57 +00002000- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2001 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2002 interpreter states; back out that fix and do a better job (see
2003 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2004 for a longer write-up of the problem).
2005
Michael W. Hudsondf888462005-06-03 14:41:55 +00002006- SF patch #1180995: marshal now uses a binary format by default when
2007 serializing floats.
2008
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002009- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2010 the routines that promise to produce IEEE 754 binary representations
2011 of floats now simply copy bytes around.
2012
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002013- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2014 278.
2015
Brett Cannonc3647ac2005-04-26 03:45:26 +00002016- patch #1109424: int, long, float, complex, and unicode now check for the
2017 proper magic slot for type conversions when subclassed. Previously the
2018 magic slot was ignored during conversion. Semantics now match the way
2019 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002020 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002021 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002022 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002023
Barry Warsawc8d907c2005-04-19 23:43:40 +00002024- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2025 NULL, now raise an AttributeError when attempting to set or delete the
2026 attribute. Previously a TypeError was raised, but this was inconsistent
2027 with the equivalent pure-Python implementation.
2028
Michael W. Hudson774479c2005-04-18 08:46:17 +00002029- It is now safe to call PyGILState_Release() before
2030 PyEval_InitThreads() (note that if there is reason to believe there
2031 are multiple threads around you still must call PyEval_InitThreads()
2032 before using the Python API; this fix is for extension modules that
2033 have no way of knowing if Python is multi-threaded yet).
2034
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002035- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2036 disabled caused a crash.
2037
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002038- Bug #1165306: instancemethod_new allowed the creation of a method
2039 with im_class == im_self == NULL, which caused a crash when called.
2040
Tim Petersecc6e6a2005-07-10 22:30:55 +00002041- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002042 fixes the crash seen in bug #1165761
2043
Raymond Hettinger96229b12005-03-11 06:49:40 +00002044- Added two new builtins, any() and all().
2045
Brett Cannon409d8f22005-03-05 06:47:57 +00002046- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002047 (e.g., ``class C(): pass`` is no longer a syntax error).

2089 can't help, but can hurt if another thread happens to get created with
2090 the same thread id).

Nick Coghlan43832302006-04-23 17:04:07 +00002286- PEP 338: new module runpy defines a run_module function to support
2287 executing modules which provide access to source code or a code object
2288 via the PEP 302 import mechanisms.

2298 in attribute values.
2299
Anthony Baxterc51ee692006-04-01 00:57:31 +00002300- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002301 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002302 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002303 module will not be built.

Tim Petersc17976e2006-04-01 00:26:53 +00002305- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2306 aren't officially supported here, and trying to use them will probably

2328
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002329- email 4.0 package now integrated. This is largely the same as the email 3.0
2330 package that was included in Python 2.3, except that PEP 8 module names are
2331 now used (e.g. mail.message instead of email.Message). The MIME classes
2332 have been moved to a subpackage (e.g. email.mime.text instead of
2333 email.MIMEText). The old names are still supported for now. Several
2334 deprecated Message methods have been removed and lots of bugs have been
2335 fixed. More details can be found in the email package documentation.

2338 (a subclass of tuple) that provides incremental decoders and encoders
2339 (a way to use stateful codecs without the stream API). Python functions
2340 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2341 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2342 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002343

2345 a ValueError instead of a StopIteration now (like file and cString.String do).
2346 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2347 called before (like file and StringIO.StringIO do).

Tim Peterse3547fd2005-12-16 23:13:57 +00002421 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2422 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2423 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2424 Ronald L. Rivest offered this advice for Python:
2425
2426 "The consensus of researchers in this area (at least as
2427 expressed at the NIST Hash Function Workshop 10/31/05),
2428 is that SHA-256 is a good choice for the time being, but
2429 that research should continue, and other alternatives may
2430 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002431
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002432- Added a subset of Fredrik Lundh's ElementTree package. Available

2590
Guido van Rossumd0641422005-02-03 15:01:24 +00002591- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2592 disables recursive traversal through instance attributes, which can
2593 be exploited in various ways.
2594
Tim Peterse3547fd2005-12-16 23:13:57 +00002595- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002596 flags on the HTTP listening socket.
2597
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002598- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2599 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2600
Fred Drakefbdeaad2006-07-29 16:56:15 +00002601- Patches #893642, #1039083: add allow_none, encoding arguments to
2602 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.

2607
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002608- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2609
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002610- Enhancements to the csv module:
2611
2612 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002613 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002614 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002615 + Dialect parameter parsing has been re-implemented to improve error
2616 reporting.
2617 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2618 dictates.
2619 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002620 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002621 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002622 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2623 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002624 + reader now allows \r characters to be quoted (previously it only allowed
2625 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002626 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002627 + Dialect classes passed to the module are no longer instantiated by
2628 the module before being parsed (the former validation scheme required
2629 this, but the mechanism was unreliable).
2630 + The dialect registry now contains instances of the internal
2631 C-coded dialect type, rather than references to python objects.
2632 + the internal c-coded dialect type is now immutable.
2633 + register_dialect now accepts the same keyword dialect specifications
2634 as the reader and writer, allowing the user to register dialects
2635 without first creating a dialect class.
2636 + a configurable limit to the size of parsed fields has been added -
2637 previously, an unmatched quote character could result in the entire
2638 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002639 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002640 the parser field size limit (returning the former limit). The initial
2641 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002642 + A line_num attribute has been added to the reader object, which tracks
2643 the number of lines read from the source iterator. This is not
2644 the same as the number of records returned, as records can span
2645 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002646 + reader and writer objects were not being registered with the cyclic-GC.
2647 This has been fixed.
2648
Brett Cannone6539c42005-01-08 02:43:53 +00002649- _DummyThread objects in the threading module now delete self.__block that is
2650 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2651 lock primitives tend to be limited in number and thus should not be wasted on
2652 a _DummyThread object. Fixes bug #1089632.
2653
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002654- The imghdr module now detects Exif files.
2655
Raymond Hettinger6065d322004-12-20 23:51:53 +00002656- StringIO.truncate() now correctly adjusts the size attribute.
2657 (Bug #951915).
2658
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002659- locale.py now uses an updated locale alias table (built using
2660 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2661 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002662 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002663
Raymond Hettinger3557f422004-12-07 12:02:02 +00002664- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2665
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002666- the pickle module no longer accepts the deprecated None option in the
2667 args tuple returned by __reduce__().
2668
Brett Cannon84667c02004-12-07 03:25:18 +00002669- optparse now optionally imports gettext. This allows its use in setup.py.
2670
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002671- the pickle module no longer uses the deprecated bin parameter.
2672
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002673- the shelve module no longer uses the deprecated binary parameter.
2674
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002675- the pstats module no longer uses the deprecated ignore() method.
2676
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002677- the filecmp module no longer uses the deprecated use_statcache argument.
2678
Raymond Hettinger664347b2004-12-04 21:21:53 +00002679- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2680 extended or overridden by subclasses. Formerly, the subclassed method would
2681 be ignored by the rest of the module. (Bug #1078905).
2682
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002683- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002684 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002685
Walter Dörwald36733692004-12-22 12:50:50 +00002686- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2687 once when a size argument is given. This prevents a buffer overflow in the
2688 tokenizer with very long source lines.
2689
Barry Warsaw538561e2006-01-01 21:48:54 +00002690- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2691 immediately after creating the object, without any intervening
2692 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002693
Skip Montanaro05885812005-01-16 20:48:27 +00002694- The reconvert.quote function can now emit triple-quoted strings. The
2695 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002696
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002697- ``UserString.MutableString`` now supports negative indices in
2698 ``__setitem__`` and ``__delitem__``
2699
Greg Ward40407942005-03-05 02:53:17 +00002700- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2701 correctly.
2702
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002703- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2704 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2705 character even if the user has passed a size parameter to get a proper
2706 line ending. Remove the special handling of a "\r\n" that has been split
2707 between two lines.
2708
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002709- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2710 about illegal code points. The codec now supports PEP 293 style error
2711 handlers.
2712
Walter Dörwald78a78b02005-09-01 12:04:29 +00002713- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002714 from the input stream, so that the output is a byte string in the correct
2715 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002716
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002717- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2718 considering it exactly like a '*'.
2719
Walter Dörwald007f8df2005-10-09 19:42:27 +00002720- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2721 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002722
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002723- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2724
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002725- Patch #1413711: Certain patterns of differences were making difflib
2726 touch the recursion limit.
2727
Walter Dörwald58917a62006-03-31 15:26:22 +00002728- Bug #947906: An object oriented interface has been added to the calendar
2729 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002730 called as a script (e.g. via ``python -mcalendar``). Localized month and
2731 weekday names can be ouput (even if an exotic encoding is used) using
2732 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002733
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002734Build
2735-----
2736
Neal Norwitz602d3392006-03-31 08:21:40 +00002737- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2738 by using -mieee gcc option.
2739

2741
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002742- Build support for Win64-AMD64 was added.
2743
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002744- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2745
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002746- Patch #881820: look for openpty and forkpty also in libbsd.
2747
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002748- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2749 The zlib module is now builtin on Windows.
2750
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002751- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2752
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002753- Bug #1189330: configure did not correctly determine the necessary
2754 value of LINKCC if python was built with GCC 4.0.
2755
Trent Mick8321b422005-07-26 02:29:21 +00002756- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2757 vulnerability in zlib 1.2.1 and 1.2.2.
2758
Brett Cannon08cd5982005-04-24 22:26:38 +00002759- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2760 flags that change binary compatibility. Changes were also made to
2761 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002762 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002763
Bob Ippolitoed233462005-03-29 13:47:59 +00002764- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2765 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2766 no longer exists). This configure patch makes things right.
2767
Martin v. Löwise2713be2005-03-08 15:03:08 +00002768- Bug #1158607: Build with --disable-unicode again.
2769
Brett Cannon46d96232005-02-16 00:07:19 +00002770- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2771 defined. Discovered as a result of not being able to build on OS X.
2772
Brett Cannon516592f2004-12-07 00:42:59 +00002773- setup.py now uses the directories specified in LDFLAGS using the -L option
2774 and in CPPFLAGS using the -I option for adding library and include
2775 directories, respectively, for compiling extension modules against. This has
2776 led to the core being compiled using the values in CPPFLAGS. It also removes
2777 the need for the special-casing of both DarwinPorts and Fink for darwin since
2778 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2779 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2780 Fink, ``-I/opt/local/include`` for DarwinPorts).
2781
Brett Cannon43802422005-02-10 20:48:03 +00002782- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2783 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2784 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2785 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002787C API
2788-----
2789
Tim Petersc9d78aa2006-03-26 23:27:58 +00002790- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2791 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2792 is obtained via the ``PyObject_`` family, it must be released via the
2793 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2794 always been officially true, but when Python's small-object allocator was
2795 introduced, an attempt was made to cater to a few extension modules
2796 discovered at the time that obtained memory via ``PyObject_New`` but
2797 released it via ``PyMem_DEL``. It's years later, and if such code still
2798 exists it will fail now (probably with segfaults, but calling wrong
2799 low-level memory management functions can yield many symptoms).
2800
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002801- Added a C API for set and frozenset objects.
2802

2804
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002805- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2806 mapping argument now. This string is used as a mapping table. Byte values
2807 greater than the length of the string and 0xFFFE are treated as undefined
2808 mappings.
