13-----------------
14
Collin Winter77c67bd2007-03-16 04:11:30 +000015- Patch #1642547: Fix an error/crash when encountering syntax errors in
16 complex if statements.
17
Žiga Seilnacht20f43d32007-03-15 11:44:55 +000018- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
19 is called with an object that is faking its type.
20
Žiga Seilnacht71436f02007-03-14 12:24:09 +000021- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
22 name.
23
Georg Brandl5240d742007-03-13 20:46:32 +000024- Patch #1444529: the builtin compile() now accepts keyword arguments.
25
Georg Brandl7b9c5552007-03-12 14:30:05 +000026- Bug #1678647: write a newline after printing an exception in any
27 case, even when converting the value to a string failed.
28
Georg Brandl871f1bc2007-03-12 13:17:36 +000029- The dir() function has been extended to call the __dir__() method on
30 its argument, if it exists. If not, it will work like before. This allows
31 customizing the output of dir() in the presence of a __getattr__().
32
Collin Winter276887b2007-03-12 16:11:39 +000033- Patch #922167: Python no longer segfaults when faced with infinitely
34 self-recursive reload() calls (as reported by bug #742342).
35
Žiga Seilnacht89032082007-03-11 15:54:54 +000036- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
37
Collin Wintere38051d2007-03-09 20:33:07 +000038- Patch #1491866: change the complex() constructor to allow parthensized
39 forms. This means complex(repr(x)) now works instead of raising a
40 ValueError.
41
Georg Brandlaa2321b2007-03-07 00:40:28 +000042- Patch #703779: unset __file__ in __main__ after running a file. This
43 makes the filenames the warning module prints much more sensible when
44 a PYTHONSTARTUP file is used.
45
Georg Brandl49aafc92007-03-07 00:34:46 +000046- Variant of patch #697613: don't exit the interpreter on a SystemExit
47 exception if the -i command line option or PYTHONINSPECT environment
48 variable is given, but break into the interactive interpreter just like
49 on other exceptions or normal program exit.
50
Georg Brandl00cd8182007-03-06 18:41:12 +000051- Patch #1638879: don't accept strings with embedded NUL bytes in long().
52

54
Georg Brandl0fca97a2007-03-05 22:28:08 +000055- Patch #1674228: when assigning a slice (old-style), check for the
56 sq_ass_slice instead of the sq_slice slot.
57
Neal Norwitz88516a62007-02-26 22:41:45 +000058- When printing an unraisable error, don't print exceptions. before the name.
59 This duplicates the behavior whening normally printing exceptions.
60
Martin v. Löwisfd963262007-02-09 12:19:32 +000061- Bug #1653736: Properly discard third argument to slot_nb_inplace_power.
62
Brett Cannon129bd522007-01-30 21:34:36 +000063- PEP 352: Raising a string exception now triggers a TypeError. Attempting to
64 catch a string exception raises DeprecationWarning.
65
Brett Cannonf5bee302007-01-23 23:21:22 +000066- Bug #1377858: Fix the segfaulting of the interpreter when an object created
67 a weakref on itself during a __del__ call for new-style classes (classic
68 classes still have the bug).
69
Martin v. Löwis6c5c5022007-01-23 21:11:47 +000070- Bug #1579370: Make PyTraceBack_Here use the current thread, not the

78 raised a warning.
79

81 to avoid relying on atexit.
82

103 if the assigned value for structmember fields gets truncated.
104
Neal Norwitzcbeb6872006-10-14 21:33:38 +0000105- Update the peephole optimizer to remove more dead code (jumps after returns)

107
Georg Brandl2c1375c2006-10-12 11:27:59 +0000108- Bug #1545497: when given an explicit base, int() did ignore NULs
109 embedded in the string to convert.
110
Georg Brandl846f73a2006-10-08 07:11:54 +0000111- Bug #1569998: break inside a try statement (outside a loop) is now

115
116- Fix some leftovers from the conversion from int to Py_ssize_t
117 (relevant to strings and sequences of more than 2**31 items).
118
119- A number of places, including integer negation and absolute value,
120 were fixed to not rely on undefined behaviour of the C compiler
121 anymore.
Martin v. Löwis820d6ac2006-10-04 05:47:34 +0000122
Georg Brandl3267d282006-09-30 09:03:42 +0000123- Bug #1566800: make sure that EnvironmentError can be called with any

139
Brett Cannon9adeab72006-09-20 18:34:28 +0000140- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
141 allows calling unicode() on exceptions classes directly to succeed.
142
Georg Brandlec6c2df2006-09-11 09:38:35 +0000143- Make _PyGILState_NoteThreadState() static, it was not used anywhere
144 outside of pystate.c and should not be necessary.
145
Georg Brandl4e933132006-09-06 20:05:58 +0000146- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

151 imports (if not in package and if beyond toplevel package).
152
Tim Petersc10c9d02006-09-05 02:18:09 +0000153- Overflow checking code in integer division ran afoul of new gcc
154 optimizations. Changed to be more standard-conforming.
155

Neal Norwitza22975f2006-09-05 02:24:03 +0000158- Patch #1546288: fix seg fault in dict_equal due to ref counting bug.
159
Neal Norwitzd34e4272006-09-05 02:36:20 +0000160- The return tuple from str.rpartition(sep) is (tail, sep, head) where
161 head is the original string if sep was not found.
162
Neal Norwitzdac090d2006-09-05 03:53:08 +0000163- Bug #1520864: unpacking singleton tuples in list comprehensions and
164 generator expressions (x for x, in ... ) works again. Fixing this problem
165 required changing the .pyc magic number. This means that .pyc files
166 generated before 2.5c2 will be regenerated.
167
Neal Norwitzca460d92006-09-06 06:28:06 +0000168- with and as are now keywords.
169
Jeremy Hyltonc5ceb252007-02-25 15:57:45 +0000170- Bug #1664966: Fix crash in exec if Unicode filename can't be decoded.

Jeremy Hyltoncca75402007-02-27 18:33:31 +0000172- Add new requirements for metaclasses. 1) If type or a subclass of type
173 occurs in __bases__, it must occur before any non-type bases, e.g.
174 before regular classes. 2) If you assign to __bases__, you may not
175 change the metaclass. Many more illegal assignments to __bases__
176 are now checked and raise TypeErrors. This changed fixed at least
177 one known crash.
178

Georg Brandl8844e432007-03-16 08:22:40 +0000182- Patch #1273829: os.walk() now has a "followlinks" parameter. If set to
183 True (which is not the default), it visits symlinks pointing to
184 directories.
185
Georg Brandl8f06d022007-03-16 07:55:09 +0000186- Bug #1681228: the webbrowser module now correctly uses the default

204 correctly now.
205
Georg Brandlbad6f192007-03-13 21:32:56 +0000206- The nonobvious commands.getstatus() function is now deprecated.

Collin Winter22c42ba2007-03-10 02:51:26 +0000262
Thomas Heller2456a3c2007-03-09 20:39:22 +0000263- Bug #1651235: When a tuple was passed to a ctypes function call,
264 Python would crash instead of raising an error.
265
Thomas Hellerc2f77252007-03-09 19:21:28 +0000266- Bug #1646630: ctypes.string_at(buf, 0) and ctypes.wstring_at(buf, 0)

274
Georg Brandl9caadf82007-03-08 18:37:31 +0000275- unittest now verifies more of its assumptions. In particular, TestCase
276 and TestSuite subclasses (not instances) are no longer accepted in
277 TestSuite.addTest(). This should cause no incompatibility since it
278 never made sense with ordinary subclasses -- the failure just occurred
279 later, with a more cumbersome exception.
280
Georg Brandld0a96252007-03-07 09:21:06 +0000281- Patch #787789: allow to pass custom TestRunner instances to unittest's

289
Skip Montanarod1287322007-03-06 15:41:38 +0000290- Patch #1673619: setup.py identifies extension modules it doesn't know how
291 to build and those it knows how to build but that fail to build.
292
Martin v. Löwisab8a6bb2007-03-06 14:43:00 +0000293- Patch #912410: Replace HTML entity references for attribute values

633 mode by only placing a timeout on the select() if an input hook has
634 been defined. This prevents an interactive Python from waking up 10
635 times per second. Patch by Richard Boulton.

658 variables.
659
Brett Cannon6d9520c2006-12-13 23:09:53 +0000660- Added guard_warnings_filter to test.test_support. It returns a context

772=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000773
Anthony Baxterb4096662006-08-16 03:42:26 +0000774*Release date: 17-AUG-2006*

776Core and builtins
777-----------------
778
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000779- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000780 compared equal or unequal to a string and a UnicodeDecodeError
781 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000782
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000783 Instead, the equal (==) and unequal (!=) comparison operators will
784 now issue a UnicodeWarning and interpret the two objects as
785 unequal. The UnicodeWarning can be filtered as desired using
786 the warning framework, e.g. silenced completely, turned into an
787 exception, logged, etc.
788
789 Note that compare operators other than equal and unequal will still
790 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000791
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000792- Fix segfault when doing string formatting on subclasses of long.
793
794- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
795 with new-style classes.
796
797- Fix bug related to __len__ functions returning negative values with
798 classic classes.
799
800- Patch #1538606, Fix __index__() clipping. There were some problems
801 discovered with the API and how integers that didn't fit into Py_ssize_t
802 were handled. This patch attempts to provide enough alternatives
803 to effectively use __index__.
804
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000805- Bug #1536021: __hash__ may now return long int; the final hash
806 value is obtained by invoking hash on the long int.
807
Thomas Hellerab1049c2006-08-08 17:37:00 +0000808- Bug #1536786: buffer comparison could emit a RuntimeWarning.
809
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000810- Bug #1535165: fixed a segfault in input() and raw_input() when
811 sys.stdin is closed.
812
Thomas Heller74d36f02006-08-04 18:17:40 +0000813- On Windows, the PyErr_Warn function is now exported from
814 the Python dll again.
815
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000816- Bug #1191458: tracing over for loops now produces a line event
817 on each iteration. Fixing this problem required changing the .pyc
818 magic number. This means that .pyc files generated before 2.5c1
819 will be regenerated.
820
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000821- Bug #1333982: string/number constants were inappropriately stored
822 in the byte code and co_consts even if they were not used, ie
823 immediately popped off the stack.
824
Georg Brandle9462c72006-08-04 18:03:37 +0000825- Fixed a reference-counting problem in property().

828Library
829-------
830
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000831- Fix a bug in the ``compiler`` package that caused invalid code to be
832 generated for generator expressions.
833
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000834- The distutils version has been changed to 2.5.0. The change to
835 keep it programmatically in sync with the Python version running
836 the code (introduced in 2.5b3) has been reverted. It will continue
837 to be maintained manually as static string literal.
838
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000839- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000840 and this cannot be converted to the required C type, an exception is
841 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000842 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000843
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000844- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000845 an exception.
846
Tim Petersc10c9d02006-09-05 02:18:09 +0000847- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000848 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000849 workarounds for clocks with low resolution, to stop the code yielding
850 duplicate UUIDs.
851
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000852- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
853 before raising SystemExit, allowing IDLE to honor quit() and exit().
854
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000855- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
856
Georg Brandl7a1af772006-08-14 21:55:28 +0000857- Patch #1536071: trace.py should now find the full module name of a
858 file correctly even on Windows.
859
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000860- logging's atexit hook now runs even if the rest of the module has
861 already been cleaned up.
862
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000863- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000864
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000865- Bug #1531405, format_exception no longer raises an exception if
866 str(exception) raised an exception.

Neil Schemenauer06ded092006-08-04 16:20:30 +0000868- Fix a bug in the ``compiler`` package that caused invalid code to be
869 generated for nested functions.

879
Thomas Heller1ce433e2006-08-14 16:20:04 +0000880- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
881 '-no-stack-protector' compiler flag for OpenBSD has been removed.
882
Thomas Heller86720042006-08-14 11:17:48 +0000883- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
884 uses the _as_parameter_ attribute when objects are passed to foreign
885 function calls. The ctypes version number was changed to 1.0.1.
886
Bob Ippolitoe6c9f982006-08-04 23:59:21 +0000887- Bug #1530559, struct.pack raises TypeError where it used to convert.
888 Passing float arguments to struct.pack when integers are expected
889 now triggers a DeprecationWarning.

939Core and builtins
940-----------------
941
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000942- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +0000943 returned a long (see PEP 353).
944
Neal Norwitzf71ec5a2006-07-30 06:57:04 +0000945- Bug #1515471: string.replace() accepts character buffers again.
946
Neal Norwitz07aadb12006-07-30 06:55:48 +0000947- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
948 This provides the proper warning for struct.pack().
949 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
950
Neal Norwitz0d62a062006-07-30 06:53:31 +0000951- Patch #1531113: Fix augmented assignment with yield expressions.
952 Also fix a SystemError when trying to assign to yield expressions.
953
Phillip J. Ebyf7575d02006-07-28 21:12:07 +0000954- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
955 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
956 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
957 excessive filesystem operations during imports.
958
Tim Petersbc24eee2006-07-27 01:14:53 +0000959- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
960 operations on signed longs that are formally undefined by C.
961 Unfortunately, at least one compiler now cares about that, so complicated
962 the code to make that compiler happy again.
963
Martin v. Löwis982e9fe2006-07-24 12:54:17 +0000964- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
965
Martin v. Löwisd22968a2006-07-24 11:54:53 +0000966- Patch #1232023: Stop including current directory in search
967 path on Windows.
968
Neal Norwitze1fdb322006-07-21 05:32:28 +0000969- Fix some potential crashes found with failmalloc.
970
Neal Norwitze7563102006-07-17 01:00:16 +0000971- Fix warnings reported by Klocwork's static analysis tool.
972
Neal Norwitz84be93b2006-07-16 01:50:38 +0000973- Bug #1512814, Fix incorrect lineno's when code within a function
974 had more than 255 blank lines.
975
Georg Brandl9dceedb2006-07-12 15:31:17 +0000976- Patch #1521179: Python now accepts the standard options ``--help`` and
977 ``--version`` as well as ``/?`` on Windows.
978
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +0000979- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +0000980 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000981 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +0000982
Tim Peters112aad32006-07-19 00:03:19 +0000983- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000984 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +0000985 new ``sys._current_frames()`` returns a dictionary with one entry,
986 mapping the faux "thread id" 0 to the current frame.
987
Ronald Oussoren3075e162006-07-25 20:28:55 +0000988- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

992-------
993
Martin v. Löwis961b91b2006-08-02 13:53:55 +0000994- Correction of patch #1455898: In the mbcs decoder, set final=False
995 for stream decoder, but final=True for the decode function.
996
Georg Brandl07fec3a2006-08-01 18:49:24 +0000997- os.urandom no longer masks unrelated exceptions like SystemExit or
998 KeyboardInterrupt.
999
Tim Peters4643c2f2006-08-10 22:45:34 +00001000- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001001 shutil.copytree on Windows
1002
Georg Brandle34ac7c2006-07-30 11:07:23 +00001003- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1004 refers to file descriptors, not file objects.
1005
Tim Petersc10c9d02006-09-05 02:18:09 +00001006- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001007 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001008 #1513611, and probably others.
1009
Georg Brandledd9b0d2006-07-29 09:33:26 +00001010- Bug #1441397: The compiler module now recognizes module and function
1011 docstrings correctly as it did in Python 2.4.
1012
Tim Peters6f681472006-07-27 23:44:37 +00001013- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1014 lost that tests are sorted by name before being run. This rarely
1015 matters for well-written tests, but can create baffling symptoms if
1016 side effects from one test to the next affect outcomes. ``DocTestFinder``
1017 has been changed to sort the list of tests it returns.
1018
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001019- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001020 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001021
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001022- Bug #978833: Really close underlying socket in _socketobject.close.
1023
Georg Brandl8c036cc2006-08-20 13:15:39 +00001024- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1025 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001026
Georg Brandlcf0c1722006-07-26 07:23:32 +00001027- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1028 to recursive calls and call it with the failing package name.
1029
Martin v. Löwis0b483032006-07-25 09:53:12 +00001030- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1031
Georg Brandlc13c34c2006-07-24 14:09:56 +00001032- Patch #1515343: Fix printing of deprecated string exceptions with a
1033 value in the traceback module.
1034
Greg Ward48fae7a2006-07-23 16:05:51 +00001035- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1036
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001037- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1038
Brett Cannoncaebe222006-07-18 04:41:36 +00001039- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1040 argument tuple. For arguments where zero is illegal, the value is forced to
1041 the minimum value that is correct. This is to support an undocumented but
1042 common way people used to fill in inconsequential information in the time
1043 tuple pre-2.4.
1044
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001045- Patch #1220874: Update the binhex module for Mach-O.
1046
Barry Warsawb110bad2006-07-21 14:51:07 +00001047- The email package has improved RFC 2231 support, specifically for
1048 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1049 (name*0=<blah>) parameter continuations. This may change the types of
1050 values returned from email.message.Message.get_param() and friends.
1051 Specifically in some cases where non-encoded continuations were used,
1052 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1053 will just return the string (since non-encoded continuations don't have
1054 charset and language parts).
1055
1056 Also, whereas % values were decoded in all parameter continuations, they are
1057 now only decoded in encoded parameter parts.
1058
Ronald Oussoren3075e162006-07-25 20:28:55 +00001059- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1060
1061- Bug #1517996: IDLE now longer shows the default Tk menu when a
1062 path browser, class browser or debugger is the frontmost window on MacOS X
1063
Barry Warsaw00decd72006-07-27 23:43:15 +00001064- Patch #1520294: Support for getset and member descriptors in types.py,
1065 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1066 of an object against these built-in types and more importantly, for getting
1067 their docstrings printed in the interactive interpreter's help() function.

1071-----------------
1072
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001073- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1074 a socket operation on a socket with a timeout, the exception will be
1075 caught correctly. Previously, the exception was not caught.
1076
Thomas Heller1393d6a2006-07-28 21:43:20 +00001077- Patch #1529514: The _ctypes extension is now compiled on more
1078 openbsd target platforms.
1079
Tim Peters9cab5932006-07-28 00:30:00 +00001080- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1081 a memory leak, affecting pickles and deep copies.
1082
Tim Petersbc24eee2006-07-27 01:14:53 +00001083- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001084 Paul Eggert.
1085
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001086- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1087
Thomas Hellerce049a02006-07-14 17:51:14 +00001088- Patch #1521817: Index range checking on ctypes arrays containing
1089 exactly one element enabled again. This allows iterating over these
1090 arrays, without the need to check the array size before.
1091
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001092- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001093 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001094 /dev/null in certain cases; this is now fixed.
1095
Thomas Heller47d7a062006-07-12 08:43:47 +00001096- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1097 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001098
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001099- Because of a misspelled preprocessor symbol, ctypes was always
1100 compiled without thread support; this is now fixed.
1101
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001102- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1103 methods now allow their database parameter to be None as the
1104 sleepycat API allows.
1105
Matt Flemingec926502006-07-28 11:27:27 +00001106- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1107 bluetooth API compared with Linux and FreeBSD.
1108
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001109Tests
1110-----
1111
1112- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1113 how long the test file should take to play. Now accepts taking 2.93 secs
1114 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1115
Georg Brandl4793aa32006-07-28 18:31:39 +00001116- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1117 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1118 run via ``regrtest.py``. Now they do.

1128- PythonLauncher now works correctly when the path to the script contains
1129 characters that are treated specially by the shell (such as quotes).
1130
1131- Bug #1527397: PythonLauncher now launches scripts with the working directory
1132 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001133 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001134 expect.

Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001145- Bug #1441486: The literal representation of -(sys.maxint - 1)
1146 again evaluates to a int object, not a long.
1147
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001148- Bug #1501934: The scope of global variables that are locally assigned
1149 using augmented assignment is now correctly determined.
1150
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001151- Bug #927248: Recursive method-wrapper objects can now safely

1153
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001154- Bug #1417699: Reject locale-specific decimal point in float()
1155 and atof().
1156
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001157- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1158 omit a default "error" argument for NULL pointer. This allows
1159 the parser to take a codec from cjkcodecs again.

Neal Norwitzfb48afa2006-07-08 05:31:37 +00001161- Bug #1519018: 'as' is now validated properly in import statements.
1162
Neal Norwitz28746ab2006-07-09 22:14:42 +00001163- On 64 bit systems, int literals that use less than 64 bits are
1164 now ints rather than longs.
1165
Neal Norwitzed657552006-07-10 00:04:44 +00001166- Bug #1512814, Fix incorrect lineno's when code at module scope
1167 started after line 256.
1168
Tim Peters32a83612006-07-10 21:08:24 +00001169- New function ``sys._current_frames()`` returns a dict mapping thread
1170 id to topmost thread stack frame. This is for expert use, and is
1171 especially useful for debugging application deadlocks. The functionality
1172 was previously available in Fazal Majid's ``threadframe`` extension
1173 module, but it wasn't possible to do this in a wholly threadsafe way from
1174 an extension.

Martin v. Löwis06c68b82006-07-10 22:11:28 +00001182- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1183
Tim Peters32a83612006-07-10 21:08:24 +00001184- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001185 environment variable to be set in order to the SDK environment
1186 for finding the compiler, include files, etc.
1187
Martin v. Löwis388a8c22006-07-06 19:28:03 +00001188- Bug #1515998: Properly generate logical ids for files in bdist_msi.
1189
Nick Coghlan2d792252006-07-06 13:47:18 +00001190- warnings.py now ignores ImportWarning by default
1191
Thomas Woutersadd19112006-07-05 11:03:49 +00001192- string.Template() now correctly handles tuple-values. Previously,
1193 multi-value tuples would raise an exception and single-value tuples would
1194 be treated as the value they contain, instead.
1195
Martin v. Löwisede77f52006-07-03 13:01:35 +00001196- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1197 even if some data are received.
1198
Martin v. Löwis45482392006-07-03 12:28:58 +00001199- Bug #1267547: Put proper recursive setup.py call into the
1200 spec file generated by bdist_rpm.
1201
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001202- Bug #1514693: Update turtle's heading when switching between
1203 degrees and radians.
1204
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001205- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001206 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001207
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001208- Bug #1514703: Only setup canvas window in turtle when the canvas
1209 is created.
1210
Martin v. Löwis7596e832006-07-01 15:33:37 +00001211- Bug #1513223: .close() of a _socketobj now releases the underlying
1212 socket again, which then gets closed as it becomes unreferenced.
1213
Fred Drake10497c82006-06-29 02:57:48 +00001214- Bug #1504333: Make sgmllib support angle brackets in quoted
1215 attribute values.
1216
1217- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1218 sgmllib ('[' and ']' were not accepted).
1219
Georg Brandl1be63af2006-06-28 20:23:25 +00001220- Fix a bug in the turtle module's end_fill function.
1221
Brett Cannon53ab5b72006-06-22 16:49:14 +00001222- Bug #1510580: The 'warnings' module improperly required that a Warning
1223 category be either a types.ClassType and a subclass of Warning. The proper
1224 check is just that it is a subclass with Warning as the documentation states.
1225
Georg Brandlad29e632006-06-21 17:45:17 +00001226- The compiler module now correctly compiles the new try-except-finally
1227 statement (bug #1509132).
1228
Neal Norwitz60373cd2006-06-22 06:30:50 +00001229- The wsgiref package is now installed properly on Unix.
1230
Vinay Sajip28e57612006-07-01 10:45:20 +00001231- A bug was fixed in logging.config.fileConfig() which caused a crash on
1232 shutdown when fileConfig() was called multiple times.
1233
Gerhard Häring762fbd32006-07-02 17:48:30 +00001234- The sqlite3 module did cut off data from the SQLite database at the first
1235 null character before sending it to a custom converter. This has been fixed
1236 now.
1237
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001238Extension Modules
1239-----------------
1240
Tim Peters112aad32006-07-19 00:03:19 +00001241- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1242 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1243 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001244
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001245- Assigning None to pointer type fields in ctypes structures possible
1246 overwrote the wrong fields, this is fixed now.
1247
1248- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1249 on non-Windows platforms.
1250
1251- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1252 integer or long, without range checking.
1253
1254- Patch #1517790: It is now possible to use custom objects in the ctypes
1255 foreign function argtypes sequence as long as they provide a from_param
1256 method, no longer is it required that the object is a ctypes type.
1257
1258- The '_ctypes' extension module now works when Python is configured
1259 with the --without-threads option.
1260
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001261- Bug #1513646: os.access on Windows now correctly determines write
1262 access, again.
1263
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001264- Bug #1512695: cPickle.loads could crash if it was interrupted with
1265 a KeyboardInterrupt.
1266
Neal Norwitza12aa882006-07-06 06:45:08 +00001267- Bug #1296433: parsing XML with a non-default encoding and
1268 a CharacterDataHandler could crash the interpreter in pyexpat.
1269
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001270- Patch #1516912: improve Modules support for OpenVMS.
1271

1273-----
1274
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001275- Automate Windows build process for the Win64 SSL module.
1276
Tim Peters32a83612006-07-10 21:08:24 +00001277- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001278 Previously, the slight difference could cause compilation errors of the
1279 'zlib' module on systems with more than one version of zlib.
1280
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001281- The MSI compileall step was fixed to also support a TARGETDIR
1282 with spaces in it.
1283
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001284- Bug #1517388: sqlite3.dll is now installed on Windows independent
1285 of Tcl/Tk.
1286
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001287- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001288 trying to be installed even though it's empty.

1293- Call os.waitpid() at the end of tests that spawn child processes in order
1294 to minimize resources (zombies).
1295
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001296Documentation
1297-------------
1298
Nick Coghlan2d792252006-07-06 13:47:18 +00001299- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1300 documentation for the warnings module.
1301
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001302- Patch #1509163: MS Toolkit Compiler no longer available.
1303
Neal Norwitz56640df2006-07-10 02:36:41 +00001304- Patch #1504046: Add documentation for xml.etree.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001311
1312Core and builtins
1313-----------------
1314
Georg Brandla56b9152006-06-19 06:35:54 +00001315- Patch #1507676: Error messages returned by invalid abstract object operations
1316 (such as iterating over an integer) have been improved and now include the
1317 type of the offending object to help with debugging.
1318
Brett Cannonea3912b2006-06-13 21:46:41 +00001319- Bug #992017: A classic class that defined a __coerce__() method that returned
1320 its arguments swapped would infinitely recurse and segfault the interpreter.
1321
Neal Norwitz909eb122006-06-12 02:13:21 +00001322- Fix the socket tests so they can be run concurrently.
1323
Neal Norwitzb9845e72006-06-12 02:11:18 +00001324- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001325 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001326
Brett Cannon22565aa2006-06-09 22:31:23 +00001327- Bug #532646: object.__call__() will continue looking for the __call__
1328 attribute on objects until one without one is found. This leads to recursion
1329 when you take a class and set its __call__ attribute to an instance of the
1330 class. Originally fixed for classic classes, but this fix is for new-style.
1331 Removes the infinite_rec_3 crasher.
1332
Georg Brandl24250812006-06-09 18:45:48 +00001333- The string and unicode methods startswith() and endswith() now accept
1334 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1335
Brett Cannonde3b0522006-06-08 17:00:45 +00001336- Buffer objects, at the C level, never used the char buffer
1337 implementation even when the char buffer for the wrapped object was
1338 explicitly requested (originally returned the read or write buffer).
1339 Now a TypeError is raised if the char buffer is not present but is
1340 requested.
1341
Georg Brandlddbaa662006-06-04 21:56:52 +00001342- Patch #1346214: Statements like "if 0: suite" are now again optimized
1343 away like they were in Python 2.4.
1344
Georg Brandlb7c8f542006-05-27 12:30:25 +00001345- Builtin exceptions are now full-blown new-style classes instead of
1346 instances pretending to be classes, which speeds up exception handling
1347 by about 80% in comparison to 2.5a2.
1348
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001349- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1350 Unicode 4.1.
1351
Georg Brandlf4ef1162006-05-26 18:03:31 +00001352- Patch #921466: sys.path_importer_cache is now used to cache valid and
1353 invalid file paths for the built-in import machinery which leads to
1354 fewer open calls on startup.
1355
Tim Peters696cf432006-05-24 21:10:40 +00001356- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1357 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1358 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1359 the number of input digits (it was and remains linear-time for bases
1360 2, 4, 8, 16 and 32).
1361
Tim Petersb713ec22006-05-23 18:45:30 +00001362- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1363 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1364 an integer close to ``sys.maxint``. This was repaired by patch
1365 #1335972, which also gives a nice speedup.
1366
Richard Jonescebbefc2006-05-23 18:28:17 +00001367- Patch #1337051: reduced size of frame objects.
1368
1369- PyErr_NewException now accepts a tuple of base classes as its
1370 "base" parameter.
1371
Richard Jones7c88dcc2006-05-23 10:37:38 +00001372- Patch #876206: function call speedup by retaining allocated frame
1373 objects.
1374
Georg Brandl7b90e162006-05-18 07:01:27 +00001375- Bug #1462152: file() now checks more thoroughly for invalid mode
1376 strings and removes a possible "U" before passing the mode to the
1377 C library function.
1378
Neal Norwitz1004a532006-05-15 07:17:23 +00001379- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1380
Neal Norwitz373f0a72006-05-15 07:04:36 +00001381- Bug #1487966: Fix SystemError with conditional expression in assignment
1382
Martin v. Löwis879768d2006-05-11 13:28:43 +00001383- WindowsError now has two error code attributes: errno, which carries
1384 the error values from errno.h, and winerror, which carries the error
1385 values from winerror.h. Previous versions put the winerror.h values
1386 (from GetLastError()) into the errno attribute.
1387
Martin v. Löwis77736712006-05-04 05:51:03 +00001388- Patch #1475845: Raise IndentationError for unexpected indent.
1389
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001390- Patch #1479181: split open() and file() from being aliases for each other.
1391
Tim Peters44bd9862006-06-01 13:49:23 +00001392- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1393 methods were always silently ignored by dictionaries when comparing keys.
1394 They are now passed through (except when using the C API function
1395 ``PyDict_GetItem()``, whose semantics did not change).
1396
1397- Bug #1456209: In some obscure cases it was possible for a class with a
1398 custom ``__eq__()`` method to confuse dict internals when class instances
1399 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1400 No, you don't have any code that did this ;-)

1408
Brett Cannon6ee7d012006-06-08 16:23:04 +00001409- Change binascii.hexlify to accept a read-only buffer instead of only a char
1410 buffer and actually follow its documentation.
1411
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001412- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1413
Nick Coghlanc649ec52006-05-29 12:43:05 +00001414- Patch #1478788 (modified version): The functional extension module has
1415 been renamed to _functools and a functools Python wrapper module added.
1416 This provides a home for additional function related utilities that are
1417 not specifically about functional programming. See PEP 309.
1418
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001419- Patch #1493701: performance enhancements for struct module.

Georg Brandl8d3342b2006-05-16 07:38:27 +00001423- Patch #1435422: zlib's compress and decompress objects now have a
1424 copy() method.
1425
Andrew MacIntyre92913322006-06-13 15:04:24 +00001426- Patch #1454481: thread stack size is now tunable at runtime for thread
1427 enabled builds on Windows and systems with Posix threads support.
1428
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001429- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1430 (up to the system limit of 32K characters).
1431
1432- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1433 As a result, these functions now raise WindowsError instead of OSError.
1434
Tim Peters7a822da2006-05-25 21:50:17 +00001435- ``time.clock()`` on Win64 should use the high-performance Windows
1436 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1437 Windows platforms).
1438
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001439- Calling Tk_Init twice is refused if the first call failed as that
1440 may deadlock.
1441
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001442- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1443 accept it without potentially using an uninitialized pointer.
1444
1445- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1446 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1447 patch numbers 1494885 and 1494902]

1454
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001455- bsddb: the __len__ method of a DB object has been fixed to return correct
1456 results. It could previously incorrectly return 0 in some cases.
1457 Fixes SF bug 1493322 (pybsddb bug 1184012).
1458
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001459- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1460 aborts the db transaction safely when a modifier callback fails.
1461 Fixes SF python patch/bug #1408584.
1462
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001463- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001464 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001465 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1466 database calls that would previously deadlock. [SF python bug #775414]
1467

1477 functions.
1478
Martin v. Löwis3798da02006-06-17 18:44:27 +00001479- Patch #812986: Update turtle output even if not tracing.
1480
Vinay Sajip28e57612006-07-01 10:45:20 +00001481- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001482 Tkinter.BaseWidget.
1483
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001484- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.

1487 classes.
1488
Georg Brandl83cc0d02006-06-14 08:50:03 +00001489- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1490 mime.types file for determining MIME types.
1491
Georg Brandl2605ca82006-06-14 06:08:31 +00001492- Bug #1339007: Shelf objects now don't raise an exception in their
1493 __del__ method when initialization failed.
1494
Martin v. Löwisd8251432006-06-14 05:21:04 +00001495- Patch #1455898: The MBCS codec now supports the incremental mode for
1496 double-byte encodings.
1497
Tim Peters43898b42006-06-14 04:09:25 +00001498- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1499 guarantee that adjacent triples in the return list always describe
1500 non-adjacent blocks. Previously, a pair of matching blocks could end
1501 up being described by multiple adjacent triples that formed a partition
1502 of the matching pair.
1503
Greg Ward0e0c9f42006-06-11 16:24:11 +00001504- Bug #1498146: fix optparse to handle Unicode strings in option help,
1505 description, and epilog.
1506
Greg Wardd1c797e2006-06-11 14:42:41 +00001507- Bug #1366250: minor optparse documentation error.
1508
Greg Ward7f547402006-06-11 00:40:49 +00001509- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1510 clarify docs.
1511
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001512- The wsgiref package has been added to the standard library.
1513
Nick Coghlan676725d2006-06-08 13:54:49 +00001514- The functions update_wrapper() and wraps() have been added to the functools
1515 module. These make it easier to copy relevant metadata from the original
1516 function when writing wrapper functions.
1517
Tim Petersd6a9eef2006-06-05 01:48:21 +00001518- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1519 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001520
Martin v. Löwis3f767792006-06-04 19:36:28 +00001521- Patch #1359618: Speed up charmap encoder by using a trie structure
1522 for lookup.
1523
Tim Petersd609b1a2006-06-02 23:22:51 +00001524- The functions in the ``pprint`` module now sort dictionaries by key
1525 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1526 if and only if its display required more than one line, although that
1527 wasn't documented. The new behavior increases predictability; e.g.,
1528 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1529
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001530- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1531 (thanks for J. J. Lee).
1532
Georg Brandl2b330372006-05-28 20:23:12 +00001533- Patch #1496206: improve urllib2 handling of passwords with respect to
1534 default HTTP and HTTPS ports.
1535
George Yoshidaf3c65de2006-05-28 16:39:09 +00001536- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1537
Bob Ippolito7298f272006-05-23 18:43:47 +00001538- Patch #1281707: speed up gzip.readline.
1539
Georg Brandlb89316f2006-05-17 15:51:16 +00001540- Patch #1180296: Two new functions were added to the locale module:
1541 format_string() to get the effect of "format % items" but locale-aware,
1542 and currency() to format a monetary number with currency sign.
1543
Georg Brandle3a25832006-05-17 14:56:04 +00001544- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1545 and several features added, such as speed and geometry control.
1546
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001547- Patch #1488881: add support for external file objects in bz2 compressed
1548 tarfiles.
1549
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001550- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1551 stdout arguments, making it possible to redirect input and output
1552 for remote debugging.
1553
1554- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1555 a couple of issues, notably handling of long file names using the
1556 GNU LONGNAME extension.
1557
1558- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1559 new flag when ``name`` is already the name of an option flag.
1560
1561- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1562 package.
1563
1564- Patch #1472854: make the rlcompleter.Completer class usable on non-
1565 UNIX platforms.
1566
1567- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1568
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001569- Bug #1472827: correctly escape newlines and tabs in attribute values in
1570 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001600What's New in Python 2.5 alpha 2?
1601=================================
1602
1603*Release date: 27-APR-2006*
1604
1605Core and builtins
1606-----------------
1607
Thomas Heller1b046642006-04-18 18:51:06 +00001608- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1609 by converting these apis from macros into exported functions again:
1610
1611 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1612 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1613 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1614 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1615 PyRun_String Py_CompileString
1616
Martin v. Löwis45294a92006-04-18 06:24:08 +00001617- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1618
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001619- All uses of PyStructSequence_InitType have been changed to initialize
1620 the type objects only once, even if the interpreter is initialized
1621 multiple times.
1622
Neal Norwitz61546162006-04-14 05:20:28 +00001623- Bug #1454485, array.array('u') could crash the interpreter. This was
1624 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1625 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1626
1627- Py_UNICODE is unsigned. It was always documented as unsigned, but
1628 due to a bug had a signed value in previous versions.
1629
Tim Peters3a5e8b12006-04-11 01:44:07 +00001630- Patch #837242: ``id()`` of any Python object always gives a positive
1631 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1632 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001633 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001634 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001635
Tim Peters3a5e8b12006-04-11 01:44:07 +00001636 def __hash__(self):
1637 return id(self) # WRONG
1638
1639 because a hash result must be a (short) Python int but it was always
1640 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001641 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001642 was always usable as a hash value before this patch. That's no longer
1643 necessarily so.
1644
1645- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001646 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001647 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001648 #1454844)
1649
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001650- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1651 involving generators that have paused outside of any ``try`` or ``with``
1652 blocks. (In 2.5a1, a paused generator that was part of a reference
1653 cycle could not be garbage collected, regardless of whether it was
1654 paused in a ``try`` or ``with`` block.)

1661
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001662- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1663 fails with an error condition.
1664
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001665- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.

1667- Bug #1117761: bsddb.*open() no longer raises an exception when using
1668 the cachesize parameter.
1669
1670- Bug #1149413: bsddb.*open() no longer raises an exception when using
1671 a temporary db (file=None) with the 'n' flag to truncate on open.
1672
1673- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1674 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001675
Armin Rigoa9017c32006-04-19 11:50:27 +00001676- Patch #1062014: AF_UNIX sockets under Linux have a special

1684 abusing errno.
1685
Tim Peters711bf302006-04-25 03:31:36 +00001686- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1687 a doctest to be skipped (the code is not run, and the expected output
1688 or exception is ignored).
1689
Nick Coghlanda2268f2006-04-24 04:37:15 +00001690- Fixed contextlib.nested to cope with exceptions being raised and
1691 caught inside exit handlers.
1692
Greg Wardab05edc2006-04-23 03:47:58 +00001693- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1694 hex, octal, or binary; add ``append_const`` action; keep going if
1695 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1696 added ``epilog`` for better help generation).
1697
Tim Peters21fbd572006-04-21 21:18:10 +00001698- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1699 called from a thread spawned as a side effect of importing a module.
1700
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001701- The pydoc module now supports documenting packages contained in
1702 .zip or .egg files.
1703
1704- The pkgutil module now has several new utility functions, such
1705 as ``walk_packages()`` to support working with packages that are either
1706 in the filesystem or zip files.
1707
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001708- The mailbox module can now modify and delete messages from
1709 mailboxes, in addition to simply reading them. Thanks to Gregory
1710 K. Johnson for writing the code, and to the 2005 Google Summer of
1711 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001712
Tim Petersc7605f22006-04-17 21:12:33 +00001713- The ``__del__`` method of class ``local`` in module ``_threading_local``
1714 returned before accomplishing any of its intended cleanup.
1715
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001716- Patch #790710: Add breakpoint command lists in pdb.

Anthony Baxtere29002c2006-04-12 12:07:31 +00001722- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1723 Windows. Bug #1469163.
1724
Phillip J. Eby47032112006-04-11 01:07:43 +00001725- The warnings, linecache, inspect, traceback, site, and doctest modules
1726 were updated to work correctly with modules imported from zipfiles or
1727 via other PEP 302 __loader__ objects.
1728
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001729- Patch #1467770: Reduce usage of subprocess._active to processes which

1741
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001742- The Makefile now has a reindent target, which runs reindent.py on
1743 the library.
1744
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001745- Patch #1470875: Building Python with MS Free Compiler

1750 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001751 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001752 CXX from --with-cxx-main, see description in README.
1753

1757
Tim Peters8931ff12006-05-13 23:28:20 +00001758- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1759 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1760 and "%zu" for unsigned integers of type ``size_t``.
1761
Anthony Baxter51bcb682006-04-05 14:51:42 +00001762Tests
1763-----
1764
Nick Coghlanda2268f2006-04-24 04:37:15 +00001765- test_contextlib now checks contextlib.nested can cope with exceptions
1766 being raised and caught inside exit handlers.
1767
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001768- test_cmd_line now checks operation of the -m and -c command switches
1769
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001770- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1771 it separately and by hand. It also wasn't cleaning up its changes to
1772 the current Decimal context.
1773
Thomas Woutersabd08882006-04-26 15:53:30 +00001774- regrtest.py now has a -M option to run tests that test the new limits of
1775 containers, on 64-bit architectures. Running these tests is only sensible
1776 on 64-bit machines with more than two gigabytes of memory. The argument

1786-------------
1787
Tim Petersb06d28c2006-05-12 01:57:59 +00001788- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1789
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001790- PEP 343: Added Context Types section to the library reference
1791 and attempted to bring other PEP 343 related documentation into
1792 line with the implementation and/or python-dev discussions.
1793
Tim Peters8dc73d22006-04-24 02:03:16 +00001794- Bug #1337990: clarified that ``doctest`` does not support examples
1795 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001803Core and builtins
1804-----------------
1805
Nick Coghlan43832302006-04-23 17:04:07 +00001806- PEP 338: -m command line switch now delegates to runpy.run_module
1807 allowing it to support modules in packages and zipfiles
1808
Martin v. Löwisc661b882006-04-20 04:54:23 +00001809- On Windows, .DLL is not an accepted file name extension for
1810 extension modules anymore; extensions are only found if they
1811 end in .PYD.
1812
Martin v. Löwisea62d252006-04-03 10:56:49 +00001813- Bug #1421664: sys.stderr.encoding is now set to the same value as
1814 sys.stdout.encoding.
1815
Neal Norwitz92e212f2006-04-03 04:48:37 +00001816- __import__ accepts keyword arguments.
1817
Georg Brandlccadf842006-03-31 18:54:53 +00001818- Patch #1460496: round() now accepts keyword arguments.
1819
Anthony Baxter262c00a2006-03-30 10:53:17 +00001820- Fixed bug #1459029 - unicode reprs were double-escaped.
1821
Hye-Shik Changd478f342006-03-23 12:32:36 +00001822- Patch #1396919: The system scope threads are reenabled on FreeBSD
1823 5.4 and later versions.
1824
Neal Norwitze98ccf62006-03-23 05:39:47 +00001825- Bug #1115379: Compiling a Unicode string with an encoding declaration
1826 now gives a SyntaxError.
1827
Georg Brandlabd1ff82006-03-18 07:59:59 +00001828- Previously, Python code had no easy way to access the contents of a
1829 cell object. Now, a ``cell_contents`` attribute has been added
1830 (closes patch #1170323).
1831
Tim Peterscf79aac2006-03-16 01:14:46 +00001832- Patch #1123430: Python's small-object allocator now returns an arena to
1833 the system ``free()`` when all memory within an arena becomes unused
1834 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1835 freed. Some applications will see a drop in virtual memory size now,
1836 especially long-running applications that, from time to time, temporarily
1837 use a large number of small objects. Note that when Python returns an
1838 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001839 platform C library will in turn return that memory to the operating system.
1840 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001841 appears to be effective at least on Microsoft C and gcc-based systems.
1842 Thanks to Evan Jones for hard work and patience.
1843
Georg Brandl533ff6f2006-03-08 18:09:27 +00001844- Patch #1434038: property() now uses the getter's docstring if there is
1845 no "doc" argument given. This makes it possible to legitimately use
1846 property() as a decorator to produce a read-only property.
1847
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001848- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1849 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1850 of requiring an int or long in slicing and a few other contexts, enabling
1851 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1852
Neal Norwitz995acdf2006-03-07 05:01:00 +00001853- Fixed various bugs reported by Coverity's Prevent tool.
1854
Brett Cannonbf364092006-03-01 04:25:17 +00001855- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1856 new exception base class, BaseException, which has a new message attribute.
1857 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1858 Raising a string exception now raises a DeprecationWarning.
1859
Thomas Woutersfb609f42006-02-28 16:37:25 +00001860- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1861 explicitly relative, using 'from .module import name' to mean 'from the same
1862 package as this module is in. Imports without dots still default to the
1863 old relative-then-absolute, unless 'from __future__ import
1864 absolute_import' is used.
1865
Brett Cannona7446e32006-02-27 23:39:10 +00001866- Properly check if 'warnings' raises an exception (usually when a filter set
1867 to "error" is triggered) when raising a warning for raising string
1868 exceptions.
1869
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001870- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00001871 The name was removed from Include/code.h.
1872
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001873- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00001874
Guido van Rossum1968ad32006-02-25 22:38:04 +00001875- Patch 1433928:
1876 - The copy module now "copies" function objects (as atomic objects).
1877 - dict.__getitem__ now looks for a __missing__ hook before raising
1878 KeyError.
1879
Tim Peters84ef21c2006-02-28 20:39:06 +00001880- PEP 343: with statement implemented. Needs ``from __future__ import
1881 with_statement``. Use of 'with' as a variable will generate a warning.
1882 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00001883 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00001884 The following objects have __context__ methods:
1885 - The built-in file type.
1886 - The thread.LockType type.
1887 - The following types defined by the threading module:
1888 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
1889 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00001890
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00001891- Fix the encodings package codec search function to only search
1892 inside its own package. Fixes problem reported in patch #1433198.
1893
1894 Note: Codec packages should implement and register their own
1895 codec search function. PEP 100 has the details.
1896
Tim Peters9ea89d22006-06-04 03:26:02 +00001897- PEP 353: Using ``Py_ssize_t`` as the index type.
1898
1899- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
1900 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
1901 now allow Python to make use of memory blocks exceeding 2**32 bytes for
1902 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
1903 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00001904
Neal Norwitzfc76d632006-01-10 06:03:13 +00001905- Patch #1400181, fix unicode string formatting to not use the locale.
1906 This is how string objects work. u'%f' could use , instead of .
1907 for the decimal point. Now both strings and unicode always use periods.
1908
Neal Norwitz671b9e32006-01-09 07:07:12 +00001909- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
1910 configure would break checking curses.h.
1911
Georg Brandlcd4d1e82005-12-27 17:37:07 +00001912- Bug #959576: The pwd module is now builtin. This allows Python to be
1913 built on UNIX platforms without $HOME set.
1914
Neal Norwitzc10978f2005-12-19 06:07:16 +00001915- Bug #1072182, fix some potential problems if characters are signed.
1916
Neal Norwitz5d0ad502005-12-19 04:27:42 +00001917- Bug #889500, fix line number on SyntaxWarning for global declarations.
1918
Neal Norwitzdb83eb32005-12-18 05:29:30 +00001919- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
1920
Neal Norwitze7214a12005-12-18 05:03:17 +00001921- Support for converting hex strings to floats no longer works.
1922 This was not portable. float('0x3') now raises a ValueError.
1923
Barry Warsaw2a38a862005-12-18 01:27:35 +00001924- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00001925 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00001926 is now displayed in interactive prompt banner.
1927
Georg Brandlfa166682005-12-17 21:45:17 +00001928- Implementation of PEP 341 - Unification of try/except and try/finally.
1929 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00001930 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00001931
Hye-Shik Chang835b2432005-12-17 04:38:31 +00001932- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
1933 now encodes backslash correctly.
1934
Martin v. Löwisb45b3152005-11-28 17:34:23 +00001935- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
1936
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001937- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00001938 and long longs.
1939
Neal Norwitz67715f02005-11-09 06:59:35 +00001940- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00001941 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001942 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00001943
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001944- Replaced most Unicode charmap codecs with new ones using the
1945 new Unicode translate string feature in the builtin charmap
1946 codec; the codecs were created from the mapping tables available
1947 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
1948 encodings now include a mapping for the Apple logo)
1949
Tim Peterse3547fd2005-12-16 23:13:57 +00001950- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00001951
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001952- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001953
Martin v. Löwisbd260da2006-02-26 19:42:26 +00001954- A new AST parser implementation was completed. The abstract
1955 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00001956 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00001957
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001958- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00001959 The following code now raises a SyntaxError: foo(a = i for i in range(10))
1960
Neal Norwitz708e51a2005-10-03 04:48:15 +00001961- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
1962
Neal Norwitz11bd1192005-10-03 00:54:56 +00001963- SF Bug #887946: fix segfault when redirecting stdin from a directory.
1964 Provide a warning when a directory is passed on the command line.
1965
Neal Norwitz40d37812005-10-02 01:48:49 +00001966- Fix segfault with invalid coding.
1967
1968- SF bug #772896: unknown encoding results in MemoryError.
1969
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00001970- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00001971 supported a __len__() method which evaluated to False when the iterator
1972 was empty.
1973
Guido van Rossum630db602005-09-20 18:49:54 +00001974- On 64-bit platforms, when __len__() returns a value that cannot be
1975 represented as a C int, raise OverflowError.
1976
Skip Montanarof8948ca2005-09-19 03:54:46 +00001977- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00001978 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00001979
Georg Brandl80bbf3f2005-09-14 19:38:29 +00001980- SF bug #893549: parsing keyword arguments was broken with a few format
1981 codes.
1982
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00001983- Changes donated by Elemental Security to make it work on AIX 5.3
1984 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
1985 bug #105470: test_pwd fails on 64bit system (Opteron).
1986
Guido van Rossum539c6622005-09-14 17:49:54 +00001987- Changes donated by Elemental Security to make it work on HP-UX 11 on
1988 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
1989
Georg Brandl4550b8d2005-08-26 06:43:52 +00001990- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00001991 (fixes bug #1119418).
1992
Martin v. Löwisd35edda2005-08-24 08:39:24 +00001993- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
1994
Barry Warsawe2eca0b2005-08-15 18:14:19 +00001995- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
1996 exceptions that cause a function to exit.
1997
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00001998- The implementation of set() and frozenset() was revised to use its
1999 own internal data structure. Memory consumption is reduced by 1/3
2000 and there are modest speed-ups as well. The API is unchanged.
2001
Tim Petersde7990b2005-07-17 23:45:23 +00002002- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2003
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002004- SF bug #1229429: PyObject_CallMethod failed to decrement some
2005 reference counts in some error exit cases.
2006
Tim Petersecc6e6a2005-07-10 22:30:55 +00002007- SF bug #1185883: Python's small-object memory allocator took over
2008 a block managed by the platform C library whenever a realloc specified
2009 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002010 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002011 portable way to copy data from the C-managed block into Python's
2012 small-object space without risking a memory fault. Python's small-object
2013 realloc now leaves such blocks under the control of the platform C
2014 realloc.
2015
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002016- SF bug #1232517: An overflow error was not detected properly when
2017 attempting to convert a large float to an int in os.utime().
2018
Raymond Hettinger3296e692005-06-29 23:29:56 +00002019- SF bug #1224347: hex longs now print with lowercase letters just
2020 like their int counterparts.
2021
Michael W. Hudson188d4362005-06-20 16:52:57 +00002022- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2023 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2024 interpreter states; back out that fix and do a better job (see
2025 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2026 for a longer write-up of the problem).
2027
Michael W. Hudsondf888462005-06-03 14:41:55 +00002028- SF patch #1180995: marshal now uses a binary format by default when
2029 serializing floats.
2030
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002031- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2032 the routines that promise to produce IEEE 754 binary representations
2033 of floats now simply copy bytes around.
2034
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002035- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2036 278.
2037
Brett Cannonc3647ac2005-04-26 03:45:26 +00002038- patch #1109424: int, long, float, complex, and unicode now check for the
2039 proper magic slot for type conversions when subclassed. Previously the
2040 magic slot was ignored during conversion. Semantics now match the way
2041 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002042 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002043 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002044 Thanks Walter D�rwald.

Barry Warsawc8d907c2005-04-19 23:43:40 +00002046- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2047 NULL, now raise an AttributeError when attempting to set or delete the
2048 attribute. Previously a TypeError was raised, but this was inconsistent
2049 with the equivalent pure-Python implementation.
2050
Michael W. Hudson774479c2005-04-18 08:46:17 +00002051- It is now safe to call PyGILState_Release() before
2052 PyEval_InitThreads() (note that if there is reason to believe there
2053 are multiple threads around you still must call PyEval_InitThreads()
2054 before using the Python API; this fix is for extension modules that
2055 have no way of knowing if Python is multi-threaded yet).
2056
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002057- Typing Ctrl-C whilst raw_input() was waiting in a build with threads

2061 with im_class == im_self == NULL, which caused a crash when called.
2062
Tim Petersecc6e6a2005-07-10 22:30:55 +00002063- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002064 fixes the crash seen in bug #1165761
2065

Brett Cannonf4189912005-04-09 02:30:16 +00002069 (e.g., ``class C(): pass`` is no longer a syntax error).
2070 Patch #1176012 added support to the 'parser' module and 'compiler' package
2071 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002072

2076 returning None.
2077
Tim Petersecc6e6a2005-07-10 22:30:55 +00002078- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002079 ('\') with a specific error message.
2080
Martin v. Löwisff232d72005-03-03 09:24:38 +00002081- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2082
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002083- Bug #1124295: the __name__ attribute of file objects was

Tim Petersecc6e6a2005-07-10 22:30:55 +00002086- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002087 an ferror() call.
2088
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002089- min() and max() now support key= arguments with the same meaning as in

Raymond Hettingera422c342005-01-11 03:03:27 +00002095- set and frozenset objects can now be marshalled. SF #1098985.
2096
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002097- Bug #1077106: Poor argument checking could cause memory corruption
2098 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002099
Jeremy Hyltonab630502005-02-04 18:44:06 +00002100- The parser did not complain about future statements in illegal
2101 positions. It once again reports a syntax error if a future
2102 statement occurs after anything other than a doc string.
2103
Neil Schemenauercf52c072005-08-12 17:34:58 +00002104- Change the %s format specifier for str objects so that it returns a
2105 unicode instance if the argument is not an instance of basestring and
2106 calling __str__ on the argument returns a unicode instance.
2107
Tim Petersf4e69282006-02-27 17:15:31 +00002108- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2109 current thread state when the auto-GIL-state machinery knows about
2110 it (since the thread state is being deleted, continuing to remember it
2111 can't help, but can hurt if another thread happens to get created with
2112 the same thread id).

2313 flag to -1 (unknown) since it can't tell from the date whether it should
2314 be set.
2315
Fred Drakead5177c2006-04-01 22:14:43 +00002316- Patch #624325: urlparse.urlparse() and urlparse.urlsplit() results
2317 now sport attributes that provide access to the parts of the result.
2318
Georg Brandl7f6b67c2006-04-01 08:35:18 +00002319- Patch #1462498: sgmllib now handles entity and character references
2320 in attribute values.
2321
Anthony Baxterc51ee692006-04-01 00:57:31 +00002322- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002323 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002324 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002325 module will not be built.
2326
Tim Petersc17976e2006-04-01 00:26:53 +00002327- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2328 aren't officially supported here, and trying to use them will probably
2329 raise an exception some day. But dicts have been allowed, and "mostly
2330 worked", so support for them won't go away without warning.
2331
Georg Brandl338ef7d2006-03-31 18:42:16 +00002332- Bug #1445068: getpass.getpass() can now be given an explicit stream
2333 argument to specify where to write the prompt.
2334

2341 key to be used for signing the uploaded code.
2342
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002343- Queue.Queue objects now support .task_done() and .join() methods
2344 to make it easier to monitor when daemon threads have completed
2345 processing all enqueued tasks. Patch #1455676.
2346
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002347- popen2.Popen objects now preserve the command in a .cmd attribute.
2348
Thomas Hellerc61c0492006-03-22 10:09:27 +00002349- Added the ctypes ffi package.
2350
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002351- email 4.0 package now integrated. This is largely the same as the email 3.0
2352 package that was included in Python 2.3, except that PEP 8 module names are
2353 now used (e.g. mail.message instead of email.Message). The MIME classes
2354 have been moved to a subpackage (e.g. email.mime.text instead of
2355 email.MIMEText). The old names are still supported for now. Several
2356 deprecated Message methods have been removed and lots of bugs have been
2357 fixed. More details can be found in the email package documentation.
2358
Walter Dörwald40108c92006-03-27 08:15:44 +00002359- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2360 (a subclass of tuple) that provides incremental decoders and encoders
2361 (a way to use stateful codecs without the stream API). Python functions
2362 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2363 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2364 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002365
Walter Dörwald067db482006-03-15 22:17:27 +00002366- Patch #1359365: Calling next() on a closed StringIO.String object raises
2367 a ValueError instead of a StopIteration now (like file and cString.String do).
2368 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2369 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002370
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002371- A regrtest option -w was added to re-run failed tests in verbose mode.

2374 interpreter to exit.
2375
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002376- The function get_count() has been added to the gc module, and gc.collect()
2377 grew an optional 'generation' argument.
2378
Martin v. Löwisfbab90e2006-03-05 13:36:04 +00002379- A library msilib to generate Windows Installer files, and a distutils

2439 LoadError as documented, instead of IOError. For compatibility,
2440 LoadError subclasses IOError.
2441

Tim Peterse3547fd2005-12-16 23:13:57 +00002443 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2444 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2445 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2446 Ronald L. Rivest offered this advice for Python:
2447
2448 "The consensus of researchers in this area (at least as
2449 expressed at the NIST Hash Function Workshop 10/31/05),
2450 is that SHA-256 is a good choice for the time being, but
2451 that research should continue, and other alternatives may
2452 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002453
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002454- Added a subset of Fredrik Lundh's ElementTree package. Available

2507 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002508 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002509

2525 parameter, but uses the usual "kwargs=None".
2526
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002527- textwrap now processes text chunks at O(n) speed instead of O(n**2).

2531 to W3C name (404 -> 'Not Found'). RFE #1216944.
2532

2547 Bug #1224621.
2548
Raymond Hettinger68c04532005-06-10 11:05:19 +00002549- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002550 roundtrip from lexed tokens back to Python source code. In addition,

2562 class at all.
2563
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002564- distutils.commands.upload was added to support uploading distribution

Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002575- Bug #1163325: Decimal infinities failed to hash. Attempting to
2576 hash a NaN raised an InvalidOperation instead of a TypeError.
2577
Tim Petersecc6e6a2005-07-10 22:30:55 +00002578- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002579 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2580
Martin v. Löwis00a73e72005-03-04 19:40:34 +00002581- Patch #1043890: Add extractall method to tarfile.
2582
Martin v. Löwisc72dd382005-03-04 13:50:17 +00002583- Patch #1075887: Don't require MSVC in distutils if there is nothing
2584 to build.
2585
Martin v. Löwis637431b2005-03-03 23:12:42 +00002586- Patch #1103407: Properly deal with tarfile iterators when untarring
2587 symbolic links on Windows.
2588

Martin v. Löwisa4dac402005-03-03 11:39:45 +00002590 profile.py if available.
2591
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00002592- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
2593
Martin v. Löwisc5574e82005-03-03 10:57:37 +00002594- Patch #1117454: Remove code to special-case cookies without values
2595 in LWPCookieJar.
2596
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00002597- Patch #1117339: Add cookielib special name tests.
2598

2600
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00002601- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
2602
Martin v. Löwisdf241532005-03-03 08:17:42 +00002603- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
2604
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00002605- Patch #1104111: Alter setup.py --help and --help-commands.
2606
Martin v. Löwis4afe1542005-03-01 08:09:28 +00002607- Patch #1121234: Properly cleanup _exit and tkerror commands.
2608
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00002609- Patch #1049151: xdrlib now unpacks booleans as True or False.
2610
Raymond Hettingerbab41432005-02-05 01:31:19 +00002611- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2612
Guido van Rossumd0641422005-02-03 15:01:24 +00002613- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2614 disables recursive traversal through instance attributes, which can
2615 be exploited in various ways.
2616
Tim Peterse3547fd2005-12-16 23:13:57 +00002617- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002618 flags on the HTTP listening socket.
2619
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002620- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2621 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2622
Fred Drakefbdeaad2006-07-29 16:56:15 +00002623- Patches #893642, #1039083: add allow_none, encoding arguments to
2624 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002625
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002626- Bug #1110478: Revert os.environ.update to do putenv again.
2627
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002628- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2629
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002630- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2631
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002632- Enhancements to the csv module:
2633
2634 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002635 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002636 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002637 + Dialect parameter parsing has been re-implemented to improve error
2638 reporting.
2639 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2640 dictates.
2641 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002642 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002643 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002644 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2645 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002646 + reader now allows \r characters to be quoted (previously it only allowed
2647 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002648 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002649 + Dialect classes passed to the module are no longer instantiated by
2650 the module before being parsed (the former validation scheme required
2651 this, but the mechanism was unreliable).
2652 + The dialect registry now contains instances of the internal
2653 C-coded dialect type, rather than references to python objects.
2654 + the internal c-coded dialect type is now immutable.
2655 + register_dialect now accepts the same keyword dialect specifications
2656 as the reader and writer, allowing the user to register dialects
2657 without first creating a dialect class.
2658 + a configurable limit to the size of parsed fields has been added -
2659 previously, an unmatched quote character could result in the entire
2660 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002661 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002662 the parser field size limit (returning the former limit). The initial
2663 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002664 + A line_num attribute has been added to the reader object, which tracks
2665 the number of lines read from the source iterator. This is not
2666 the same as the number of records returned, as records can span
2667 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002668 + reader and writer objects were not being registered with the cyclic-GC.
2669 This has been fixed.
2670
Brett Cannone6539c42005-01-08 02:43:53 +00002671- _DummyThread objects in the threading module now delete self.__block that is
2672 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2673 lock primitives tend to be limited in number and thus should not be wasted on
2674 a _DummyThread object. Fixes bug #1089632.
2675
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002676- The imghdr module now detects Exif files.
2677
Raymond Hettinger6065d322004-12-20 23:51:53 +00002678- StringIO.truncate() now correctly adjusts the size attribute.
2679 (Bug #951915).
2680
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002681- locale.py now uses an updated locale alias table (built using
2682 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2683 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002684 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002685
Raymond Hettinger3557f422004-12-07 12:02:02 +00002686- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2687
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002688- the pickle module no longer accepts the deprecated None option in the
2689 args tuple returned by __reduce__().
2690
Brett Cannon84667c02004-12-07 03:25:18 +00002691- optparse now optionally imports gettext. This allows its use in setup.py.
2692
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002693- the pickle module no longer uses the deprecated bin parameter.
2694
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002695- the shelve module no longer uses the deprecated binary parameter.
2696
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002697- the pstats module no longer uses the deprecated ignore() method.
2698
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002699- the filecmp module no longer uses the deprecated use_statcache argument.
2700
Raymond Hettinger664347b2004-12-04 21:21:53 +00002701- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2702 extended or overridden by subclasses. Formerly, the subclassed method would
2703 be ignored by the rest of the module. (Bug #1078905).
2704
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002705- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002706 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002707
Walter Dörwald36733692004-12-22 12:50:50 +00002708- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2709 once when a size argument is given. This prevents a buffer overflow in the
2710 tokenizer with very long source lines.
2711
Barry Warsaw538561e2006-01-01 21:48:54 +00002712- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2713 immediately after creating the object, without any intervening
2714 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002715
Skip Montanaro05885812005-01-16 20:48:27 +00002716- The reconvert.quote function can now emit triple-quoted strings. The
2717 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002718
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002719- ``UserString.MutableString`` now supports negative indices in
2720 ``__setitem__`` and ``__delitem__``
2721
Greg Ward40407942005-03-05 02:53:17 +00002722- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2723 correctly.
2724
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002725- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2726 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2727 character even if the user has passed a size parameter to get a proper
2728 line ending. Remove the special handling of a "\r\n" that has been split
2729 between two lines.
2730
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002731- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2732 about illegal code points. The codec now supports PEP 293 style error
2733 handlers.
2734
Walter Dörwald78a78b02005-09-01 12:04:29 +00002735- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002736 from the input stream, so that the output is a byte string in the correct
2737 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002738
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002739- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2740 considering it exactly like a '*'.
2741
Walter Dörwald007f8df2005-10-09 19:42:27 +00002742- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2743 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002744
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002745- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2746
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002747- Patch #1413711: Certain patterns of differences were making difflib
2748 touch the recursion limit.
2749
Walter Dörwald58917a62006-03-31 15:26:22 +00002750- Bug #947906: An object oriented interface has been added to the calendar
2751 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002752 called as a script (e.g. via ``python -mcalendar``). Localized month and
2753 weekday names can be ouput (even if an exotic encoding is used) using
2754 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002755

2757-----
2758
Neal Norwitz602d3392006-03-31 08:21:40 +00002759- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2760 by using -mieee gcc option.
2761
Martin v. Löwis86d66262006-02-17 08:40:11 +00002762- Patch #1432345: Make python compile on DragonFly.
2763
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002764- Build support for Win64-AMD64 was added.
2765
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002766- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2767
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002768- Patch #881820: look for openpty and forkpty also in libbsd.
2769
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002770- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2771 The zlib module is now builtin on Windows.
2772
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002773- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2774
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002775- Bug #1189330: configure did not correctly determine the necessary
2776 value of LINKCC if python was built with GCC 4.0.
2777
Trent Mick8321b422005-07-26 02:29:21 +00002778- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2779 vulnerability in zlib 1.2.1 and 1.2.2.
2780
Brett Cannon08cd5982005-04-24 22:26:38 +00002781- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2782 flags that change binary compatibility. Changes were also made to
2783 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002784 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002785
Bob Ippolitoed233462005-03-29 13:47:59 +00002786- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2787 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2788 no longer exists). This configure patch makes things right.
2789
Martin v. Löwise2713be2005-03-08 15:03:08 +00002790- Bug #1158607: Build with --disable-unicode again.
2791
Brett Cannon46d96232005-02-16 00:07:19 +00002792- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2793 defined. Discovered as a result of not being able to build on OS X.
2794
Brett Cannon516592f2004-12-07 00:42:59 +00002795- setup.py now uses the directories specified in LDFLAGS using the -L option
2796 and in CPPFLAGS using the -I option for adding library and include
2797 directories, respectively, for compiling extension modules against. This has
2798 led to the core being compiled using the values in CPPFLAGS. It also removes
2799 the need for the special-casing of both DarwinPorts and Fink for darwin since
2800 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2801 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2802 Fink, ``-I/opt/local/include`` for DarwinPorts).
2803
Brett Cannon43802422005-02-10 20:48:03 +00002804- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2805 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2806 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2807 Closes bug #1096244. Thanks Gregory Bond.

2810-----
2811
Tim Petersc9d78aa2006-03-26 23:27:58 +00002812- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2813 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2814 is obtained via the ``PyObject_`` family, it must be released via the
2815 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2816 always been officially true, but when Python's small-object allocator was
2817 introduced, an attempt was made to cater to a few extension modules
2818 discovered at the time that obtained memory via ``PyObject_New`` but
2819 released it via ``PyMem_DEL``. It's years later, and if such code still
2820 exists it will fail now (probably with segfaults, but calling wrong
2821 low-level memory management functions can yield many symptoms).
2822
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002823- Added a C API for set and frozenset objects.
2824
Raymond Hettinger66517482004-12-03 11:45:13 +00002825- Removed PyRange_New().
2826
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002827- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2828 mapping argument now. This string is used as a mapping table. Byte values
2829 greater than the length of the string and 0xFFFE are treated as undefined
2830 mappings.

Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002838- Patch #1276356: New resource "urlfetch" is implemented. This enables
