8=================================
Martin v. Löwis2eb8c4f2006-08-18 03:47:18 +00009
Neal Norwitz92422fb2006-08-18 03:57:54 +000010*Release date: XX-XXX-200X*
11
12Core and builtins
13-----------------
14
Georg Brandla5ea6892007-06-01 11:33:33 +000015- Bug #1722484: remove docstrings again when running with -OO.
16
Neal Norwitz0ac60192007-05-27 04:08:54 +000017- Add new attribute names for function objects. All the func_* become
18 __*__ attributes. (Some already existed, e.g., __doc__ and __name__.)
19
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +000020- Add -3 option to the interpreter to warn about features that are
21 deprecated and will be changed/removed in Python 3.0.
22
Georg Brandl2134e752007-05-21 20:34:16 +000023- Patch #1686487: you can now pass any mapping after '**' in function
24 calls.
25
Collin Winter62903052007-05-18 23:11:24 +000026- except clauses may now be spelled either "except E, target:" or
27 "except E as target:". This is to provide forwards compatibility with
28 Python 3.0.
29
Brett Cannon229cee22007-05-05 01:34:02 +000030- Deprecate BaseException.message as per PEP 352.
31
Armin Rigo9790a272007-05-02 19:23:31 +000032- Bug #1303614: don't expose object's __dict__ when the dict is
33 inherited from a builtin base.
34
Vinay Sajip8549ce32007-05-06 17:53:37 +000035- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +000036 setting a plain string, ie don't expand to single letter identifiers.
37
Raymond Hettinger13936692007-04-11 18:40:58 +000038- Request #1191699: Slices can now be pickled.
39
Raymond Hettinger4db5fe92007-04-12 04:10:00 +000040- Request #1193128: str.translate() now allows a None argument for
41 translations that only remove characters without re-mapping the
42 remaining characters.
43
Georg Brandl5cb76c12007-03-21 09:00:39 +000044- Patch #1682205: a TypeError while unpacking an iterable is no longer
45 masked by a generic one with the message "unpack non-sequence".
46
Neal Norwitzaa754b72007-03-21 06:39:48 +000047- Remove unused file Python/fmod.c.
48
Guido van Rossum143b5642007-03-23 04:58:42 +000049- Bug #1683368: The object.__init__() and object.__new__() methods are
50 now stricter in rejecting excess arguments. The only time when
51 either allows excess arguments is when it is not overridden and the
52 other one is. For backwards compatibility, when both are
53 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +000054 warning later). Also, type.__init__() insists on the same signature
55 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +000056
Georg Brandl2b869942007-03-17 16:08:45 +000057- Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
58 to complex using its __complex__() method before falling back to the
59 __float__() method. Therefore, the functions in the cmath module now
60 can operate on objects that define a __complex__() method.
61
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +000062- Patch #1623563: allow __class__ assignment for classes with __slots__.
63 The old and the new class are still required to have the same slot names.
64
Collin Winter77c67bd2007-03-16 04:11:30 +000065- Patch #1642547: Fix an error/crash when encountering syntax errors in
66 complex if statements.
67
Žiga Seilnacht20f43d32007-03-15 11:44:55 +000068- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
69 is called with an object that is faking its type.
70
Žiga Seilnacht71436f02007-03-14 12:24:09 +000071- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
72 name.
73
Georg Brandl5240d742007-03-13 20:46:32 +000074- Patch #1444529: the builtin compile() now accepts keyword arguments.
75
Georg Brandl7b9c5552007-03-12 14:30:05 +000076- Bug #1678647: write a newline after printing an exception in any
77 case, even when converting the value to a string failed.
78
Georg Brandl871f1bc2007-03-12 13:17:36 +000079- The dir() function has been extended to call the __dir__() method on
80 its argument, if it exists. If not, it will work like before. This allows
81 customizing the output of dir() in the presence of a __getattr__().
82
Collin Winter276887b2007-03-12 16:11:39 +000083- Patch #922167: Python no longer segfaults when faced with infinitely
84 self-recursive reload() calls (as reported by bug #742342).
85
Žiga Seilnacht89032082007-03-11 15:54:54 +000086- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
87
Collin Wintere38051d2007-03-09 20:33:07 +000088- Patch #1491866: change the complex() constructor to allow parthensized
89 forms. This means complex(repr(x)) now works instead of raising a
90 ValueError.
91
Georg Brandlaa2321b2007-03-07 00:40:28 +000092- Patch #703779: unset __file__ in __main__ after running a file. This
93 makes the filenames the warning module prints much more sensible when
94 a PYTHONSTARTUP file is used.
95
Georg Brandl49aafc92007-03-07 00:34:46 +000096- Variant of patch #697613: don't exit the interpreter on a SystemExit
97 exception if the -i command line option or PYTHONINSPECT environment
98 variable is given, but break into the interactive interpreter just like
99 on other exceptions or normal program exit.
100
Georg Brandl00cd8182007-03-06 18:41:12 +0000101- Patch #1638879: don't accept strings with embedded NUL bytes in long().
102
Georg Brandl098cd692007-03-06 12:17:50 +0000103- Bug #1674503: close the file opened by execfile() in an error condition.
104
Georg Brandl0fca97a2007-03-05 22:28:08 +0000105- Patch #1674228: when assigning a slice (old-style), check for the
106 sq_ass_slice instead of the sq_slice slot.
107
Neal Norwitz88516a62007-02-26 22:41:45 +0000108- When printing an unraisable error, don't print exceptions. before the name.
109 This duplicates the behavior whening normally printing exceptions.
110
Martin v. Löwisfd963262007-02-09 12:19:32 +0000111- Bug #1653736: Properly discard third argument to slot_nb_inplace_power.
112
Brett Cannon129bd522007-01-30 21:34:36 +0000113- PEP 352: Raising a string exception now triggers a TypeError. Attempting to
114 catch a string exception raises DeprecationWarning.
115
Brett Cannonf5bee302007-01-23 23:21:22 +0000116- Bug #1377858: Fix the segfaulting of the interpreter when an object created
117 a weakref on itself during a __del__ call for new-style classes (classic
118 classes still have the bug).
119
Martin v. Löwis6c5c5022007-01-23 21:11:47 +0000120- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
121 frame's thread state.
122
Thomas Wouters6ed19652007-01-23 13:50:49 +0000123- patch #1630975: Fix crash when replacing sys.stdout in sitecustomize.py
124
Martin v. Löwis4885e7d2007-01-19 06:42:22 +0000125- Bug #1637022: Prefix AST symbols with _Py_.
126
Neal Norwitz72cd02c2007-01-05 05:25:22 +0000127- Prevent seg fault on shutdown which could occur if an object
128 raised a warning.
129
Martin v. Löwis7b7c9d42007-01-04 21:06:12 +0000130- Bug #1566280: Explicitly invoke threading._shutdown from Py_Main,
131 to avoid relying on atexit.
132
Raymond Hettinger94547f72006-12-20 06:42:06 +0000133- Bug #1590891: random.randrange don't return correct value for big number

Georg Brandlb9f4ad32006-10-29 18:31:42 +0000144- Bug #1576657: when setting a KeyError for a tuple key, make sure that
145 the tuple isn't used as the "exception arguments tuple".
146
Neal Norwitz21997af2006-10-28 21:19:07 +0000147- Bug #1565514, SystemError not raised on too many nested blocks.
148
Thomas Hellerdf08f0b2006-10-27 18:31:36 +0000149- Bug #1576174: WindowsError now displays the windows error code
150 again, no longer the posix error code.
151
Martin v. Löwisb5bc5372006-10-27 06:16:31 +0000152- Patch #1549049: Support long values in structmember, issue warnings
153 if the assigned value for structmember fields gets truncated.
154
Neal Norwitzcbeb6872006-10-14 21:33:38 +0000155- Update the peephole optimizer to remove more dead code (jumps after returns)
156 and inline unconditional jumps to returns.
157
Georg Brandl2c1375c2006-10-12 11:27:59 +0000158- Bug #1545497: when given an explicit base, int() did ignore NULs
159 embedded in the string to convert.
160
Georg Brandl846f73a2006-10-08 07:11:54 +0000161- Bug #1569998: break inside a try statement (outside a loop) is now
162 recognized and rejected.
163
Armin Rigo7ccbca92006-10-04 12:17:45 +0000164- list.pop(x) accepts any object x following the __index__ protocol.
165
166- Fix some leftovers from the conversion from int to Py_ssize_t
167 (relevant to strings and sequences of more than 2**31 items).
168
169- A number of places, including integer negation and absolute value,
170 were fixed to not rely on undefined behaviour of the C compiler
171 anymore.
Martin v. Löwis820d6ac2006-10-04 05:47:34 +0000172

178 use them).
179
Georg Brandla10d3af2006-09-24 12:35:36 +0000180- Fix a bug in the parser's future statement handling that led to "with"

189
Brett Cannon9adeab72006-09-20 18:34:28 +0000190- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This

192
Georg Brandlec6c2df2006-09-11 09:38:35 +0000193- Make _PyGILState_NoteThreadState() static, it was not used anywhere

201 imports (if not in package and if beyond toplevel package).
202
Tim Petersc10c9d02006-09-05 02:18:09 +0000203- Overflow checking code in integer division ran afoul of new gcc
204 optimizations. Changed to be more standard-conforming.

212
Neal Norwitzdac090d2006-09-05 03:53:08 +0000213- Bug #1520864: unpacking singleton tuples in list comprehensions and

396 and TestSuite subclasses (not instances) are no longer accepted in

931Core and builtins
932-----------------
933
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000934- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000935 compared equal or unequal to a string and a UnicodeDecodeError
936 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000937
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000938 Instead, the equal (==) and unequal (!=) comparison operators will
939 now issue a UnicodeWarning and interpret the two objects as
940 unequal. The UnicodeWarning can be filtered as desired using
941 the warning framework, e.g. silenced completely, turned into an
942 exception, logged, etc.
943
944 Note that compare operators other than equal and unequal will still
945 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000946
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000947- Fix segfault when doing string formatting on subclasses of long.
948
949- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
950 with new-style classes.
951
952- Fix bug related to __len__ functions returning negative values with
953 classic classes.
954
955- Patch #1538606, Fix __index__() clipping. There were some problems
956 discovered with the API and how integers that didn't fit into Py_ssize_t
957 were handled. This patch attempts to provide enough alternatives
958 to effectively use __index__.
959
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000960- Bug #1536021: __hash__ may now return long int; the final hash
961 value is obtained by invoking hash on the long int.
962
Thomas Hellerab1049c2006-08-08 17:37:00 +0000963- Bug #1536786: buffer comparison could emit a RuntimeWarning.
964
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000965- Bug #1535165: fixed a segfault in input() and raw_input() when
966 sys.stdin is closed.
967
Thomas Heller74d36f02006-08-04 18:17:40 +0000968- On Windows, the PyErr_Warn function is now exported from
969 the Python dll again.
970
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000971- Bug #1191458: tracing over for loops now produces a line event
972 on each iteration. Fixing this problem required changing the .pyc
973 magic number. This means that .pyc files generated before 2.5c1
974 will be regenerated.
975
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000976- Bug #1333982: string/number constants were inappropriately stored
977 in the byte code and co_consts even if they were not used, ie
978 immediately popped off the stack.
979
Georg Brandle9462c72006-08-04 18:03:37 +0000980- Fixed a reference-counting problem in property().

983Library
984-------
985
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000986- Fix a bug in the ``compiler`` package that caused invalid code to be
987 generated for generator expressions.
988
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000989- The distutils version has been changed to 2.5.0. The change to
990 keep it programmatically in sync with the Python version running
991 the code (introduced in 2.5b3) has been reverted. It will continue
992 to be maintained manually as static string literal.
993
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000994- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000995 and this cannot be converted to the required C type, an exception is
996 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000997 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000998
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000999- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001000 an exception.
1001
Tim Petersc10c9d02006-09-05 02:18:09 +00001002- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001003 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001004 workarounds for clocks with low resolution, to stop the code yielding
1005 duplicate UUIDs.
1006
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001007- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1008 before raising SystemExit, allowing IDLE to honor quit() and exit().
1009
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001010- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1011
Georg Brandl7a1af772006-08-14 21:55:28 +00001012- Patch #1536071: trace.py should now find the full module name of a
1013 file correctly even on Windows.
1014
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001015- logging's atexit hook now runs even if the rest of the module has
1016 already been cleaned up.
1017
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001018- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001019
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001020- Bug #1531405, format_exception no longer raises an exception if
1021 str(exception) raised an exception.
1022
Neil Schemenauer06ded092006-08-04 16:20:30 +00001023- Fix a bug in the ``compiler`` package that caused invalid code to be
1024 generated for nested functions.

1033 raises the correct exceptions.
1034
Thomas Heller1ce433e2006-08-14 16:20:04 +00001035- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1036 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1037
Thomas Heller86720042006-08-14 11:17:48 +00001038- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1039 uses the _as_parameter_ attribute when objects are passed to foreign
1040 function calls. The ctypes version number was changed to 1.0.1.
1041
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001042- Bug #1530559, struct.pack raises TypeError where it used to convert.
1043 Passing float arguments to struct.pack when integers are expected
1044 now triggers a DeprecationWarning.

1082
Tim Peters4643c2f2006-08-10 22:45:34 +00001083- Bug #1069160. Internal correctness changes were made to
1084 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1085 the documentation was changed to state that the return value
1086 is always 1 (normal) or 0 (if the specified thread wasn't found).

1094Core and builtins
1095-----------------
1096
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001097- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001098 returned a long (see PEP 353).
1099
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001100- Bug #1515471: string.replace() accepts character buffers again.
1101
Neal Norwitz07aadb12006-07-30 06:55:48 +00001102- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1103 This provides the proper warning for struct.pack().
1104 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1105
Neal Norwitz0d62a062006-07-30 06:53:31 +00001106- Patch #1531113: Fix augmented assignment with yield expressions.
1107 Also fix a SystemError when trying to assign to yield expressions.
1108
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001109- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1110 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1111 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1112 excessive filesystem operations during imports.
1113
Tim Petersbc24eee2006-07-27 01:14:53 +00001114- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1115 operations on signed longs that are formally undefined by C.
1116 Unfortunately, at least one compiler now cares about that, so complicated
1117 the code to make that compiler happy again.
1118
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001119- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1120
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001121- Patch #1232023: Stop including current directory in search
1122 path on Windows.
1123
Neal Norwitze1fdb322006-07-21 05:32:28 +00001124- Fix some potential crashes found with failmalloc.
1125
Neal Norwitze7563102006-07-17 01:00:16 +00001126- Fix warnings reported by Klocwork's static analysis tool.
1127
Neal Norwitz84be93b2006-07-16 01:50:38 +00001128- Bug #1512814, Fix incorrect lineno's when code within a function
1129 had more than 255 blank lines.
1130
Georg Brandl9dceedb2006-07-12 15:31:17 +00001131- Patch #1521179: Python now accepts the standard options ``--help`` and
1132 ``--version`` as well as ``/?`` on Windows.
1133
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001134- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001135 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001136 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001137
Tim Peters112aad32006-07-19 00:03:19 +00001138- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001139 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001140 new ``sys._current_frames()`` returns a dictionary with one entry,
1141 mapping the faux "thread id" 0 to the current frame.
1142
Ronald Oussoren3075e162006-07-25 20:28:55 +00001143- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001144

1147-------
1148
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001149- Correction of patch #1455898: In the mbcs decoder, set final=False
1150 for stream decoder, but final=True for the decode function.
1151
Georg Brandl07fec3a2006-08-01 18:49:24 +00001152- os.urandom no longer masks unrelated exceptions like SystemExit or
1153 KeyboardInterrupt.
1154
Tim Peters4643c2f2006-08-10 22:45:34 +00001155- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001156 shutil.copytree on Windows
1157
Georg Brandle34ac7c2006-07-30 11:07:23 +00001158- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1159 refers to file descriptors, not file objects.
1160
Tim Petersc10c9d02006-09-05 02:18:09 +00001161- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001162 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001163 #1513611, and probably others.
1164
Georg Brandledd9b0d2006-07-29 09:33:26 +00001165- Bug #1441397: The compiler module now recognizes module and function
1166 docstrings correctly as it did in Python 2.4.
1167
Tim Peters6f681472006-07-27 23:44:37 +00001168- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1169 lost that tests are sorted by name before being run. This rarely
1170 matters for well-written tests, but can create baffling symptoms if
1171 side effects from one test to the next affect outcomes. ``DocTestFinder``
1172 has been changed to sort the list of tests it returns.
1173
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001174- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001175 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001176
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001177- Bug #978833: Really close underlying socket in _socketobject.close.
1178
Georg Brandl8c036cc2006-08-20 13:15:39 +00001179- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1180 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001181
Georg Brandlcf0c1722006-07-26 07:23:32 +00001182- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1183 to recursive calls and call it with the failing package name.
1184
Martin v. Löwis0b483032006-07-25 09:53:12 +00001185- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1186
Georg Brandlc13c34c2006-07-24 14:09:56 +00001187- Patch #1515343: Fix printing of deprecated string exceptions with a
1188 value in the traceback module.
1189
Greg Ward48fae7a2006-07-23 16:05:51 +00001190- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1191
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001192- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1193
Brett Cannoncaebe222006-07-18 04:41:36 +00001194- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1195 argument tuple. For arguments where zero is illegal, the value is forced to
1196 the minimum value that is correct. This is to support an undocumented but
1197 common way people used to fill in inconsequential information in the time
1198 tuple pre-2.4.
1199
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001200- Patch #1220874: Update the binhex module for Mach-O.
1201
Barry Warsawb110bad2006-07-21 14:51:07 +00001202- The email package has improved RFC 2231 support, specifically for
1203 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1204 (name*0=<blah>) parameter continuations. This may change the types of
1205 values returned from email.message.Message.get_param() and friends.
1206 Specifically in some cases where non-encoded continuations were used,
1207 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1208 will just return the string (since non-encoded continuations don't have
1209 charset and language parts).
1210
1211 Also, whereas % values were decoded in all parameter continuations, they are
1212 now only decoded in encoded parameter parts.
1213
Ronald Oussoren3075e162006-07-25 20:28:55 +00001214- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1215
1216- Bug #1517996: IDLE now longer shows the default Tk menu when a
1217 path browser, class browser or debugger is the frontmost window on MacOS X
1218
Barry Warsaw00decd72006-07-27 23:43:15 +00001219- Patch #1520294: Support for getset and member descriptors in types.py,
1220 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1221 of an object against these built-in types and more importantly, for getting
1222 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001225Extension Modules
1226-----------------
1227
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001228- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1229 a socket operation on a socket with a timeout, the exception will be
1230 caught correctly. Previously, the exception was not caught.
1231
Thomas Heller1393d6a2006-07-28 21:43:20 +00001232- Patch #1529514: The _ctypes extension is now compiled on more
1233 openbsd target platforms.
1234
Tim Peters9cab5932006-07-28 00:30:00 +00001235- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1236 a memory leak, affecting pickles and deep copies.
1237
Tim Petersbc24eee2006-07-27 01:14:53 +00001238- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001239 Paul Eggert.
1240

1242
Thomas Hellerce049a02006-07-14 17:51:14 +00001243- Patch #1521817: Index range checking on ctypes arrays containing
1244 exactly one element enabled again. This allows iterating over these
1245 arrays, without the need to check the array size before.
1246
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001247- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001248 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001249 /dev/null in certain cases; this is now fixed.
1250
Thomas Heller47d7a062006-07-12 08:43:47 +00001251- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1252 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001253
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001254- Because of a misspelled preprocessor symbol, ctypes was always
1255 compiled without thread support; this is now fixed.
1256
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001257- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1258 methods now allow their database parameter to be None as the
1259 sleepycat API allows.
1260
Matt Flemingec926502006-07-28 11:27:27 +00001261- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1262 bluetooth API compared with Linux and FreeBSD.
1263
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001264Tests
1265-----
1266
1267- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1268 how long the test file should take to play. Now accepts taking 2.93 secs
1269 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1270
Georg Brandl4793aa32006-07-28 18:31:39 +00001271- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1272 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1273 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +00001274
Martin v. Löwis0907f4d2006-07-30 14:09:47 +00001275Build
1276-----
1277
1278- Bug #1439538: Drop usage of test -e in configure as it is not portable.
1279
Ronald Oussoren26cad082006-08-01 21:00:57 +00001280Mac
1281---
1282
1283- PythonLauncher now works correctly when the path to the script contains
1284 characters that are treated specially by the shell (such as quotes).
1285
1286- Bug #1527397: PythonLauncher now launches scripts with the working directory
1287 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001288 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001289 expect.

1298-----------------
1299
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001300- Bug #1441486: The literal representation of -(sys.maxint - 1)
1301 again evaluates to a int object, not a long.
1302
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001303- Bug #1501934: The scope of global variables that are locally assigned
1304 using augmented assignment is now correctly determined.
1305
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001306- Bug #927248: Recursive method-wrapper objects can now safely
1307 be released.
1308
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001309- Bug #1417699: Reject locale-specific decimal point in float()
1310 and atof().
1311
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001312- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1313 omit a default "error" argument for NULL pointer. This allows
1314 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001315
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001316- Bug #1519018: 'as' is now validated properly in import statements.
1317
Neal Norwitz28746ab2006-07-09 22:14:42 +00001318- On 64 bit systems, int literals that use less than 64 bits are
1319 now ints rather than longs.
1320
Neal Norwitzed657552006-07-10 00:04:44 +00001321- Bug #1512814, Fix incorrect lineno's when code at module scope
1322 started after line 256.
1323
Tim Peters32a83612006-07-10 21:08:24 +00001324- New function ``sys._current_frames()`` returns a dict mapping thread
1325 id to topmost thread stack frame. This is for expert use, and is
1326 especially useful for debugging application deadlocks. The functionality
1327 was previously available in Fazal Majid's ``threadframe`` extension
1328 module, but it wasn't possible to do this in a wholly threadsafe way from
1329 an extension.
1330

1346
Thomas Woutersadd19112006-07-05 11:03:49 +00001347- string.Template() now correctly handles tuple-values. Previously,
1348 multi-value tuples would raise an exception and single-value tuples would
1349 be treated as the value they contain, instead.
1350
Martin v. Löwisede77f52006-07-03 13:01:35 +00001351- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1356
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001357- Bug #1514693: Update turtle's heading when switching between
1358 degrees and radians.
1359
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001360- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001361 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001362

1364 is created.
1365
Martin v. Löwis7596e832006-07-01 15:33:37 +00001366- Bug #1513223: .close() of a _socketobj now releases the underlying
1367 socket again, which then gets closed as it becomes unreferenced.
1368
Fred Drake10497c82006-06-29 02:57:48 +00001369- Bug #1504333: Make sgmllib support angle brackets in quoted
1370 attribute values.

1372- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1373 sgmllib ('[' and ']' were not accepted).
1374
Georg Brandl1be63af2006-06-28 20:23:25 +00001375- Fix a bug in the turtle module's end_fill function.
1376
Brett Cannon53ab5b72006-06-22 16:49:14 +00001377- Bug #1510580: The 'warnings' module improperly required that a Warning
1378 category be either a types.ClassType and a subclass of Warning. The proper
1379 check is just that it is a subclass with Warning as the documentation states.
1380
Georg Brandlad29e632006-06-21 17:45:17 +00001381- The compiler module now correctly compiles the new try-except-finally
1382 statement (bug #1509132).
1383
Neal Norwitz60373cd2006-06-22 06:30:50 +00001384- The wsgiref package is now installed properly on Unix.
1385
Vinay Sajip28e57612006-07-01 10:45:20 +00001386- A bug was fixed in logging.config.fileConfig() which caused a crash on
1387 shutdown when fileConfig() was called multiple times.
1388
Gerhard Häring762fbd32006-07-02 17:48:30 +00001389- The sqlite3 module did cut off data from the SQLite database at the first
1390 null character before sending it to a custom converter. This has been fixed
1391 now.
1392
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001393Extension Modules
1394-----------------
1395
Tim Peters112aad32006-07-19 00:03:19 +00001396- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1397 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1398 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001399
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001400- Assigning None to pointer type fields in ctypes structures possible
1401 overwrote the wrong fields, this is fixed now.
1402
1403- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1404 on non-Windows platforms.
1405
1406- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1407 integer or long, without range checking.
1408
1409- Patch #1517790: It is now possible to use custom objects in the ctypes
1410 foreign function argtypes sequence as long as they provide a from_param
1411 method, no longer is it required that the object is a ctypes type.
1412
1413- The '_ctypes' extension module now works when Python is configured
1414 with the --without-threads option.
1415
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001416- Bug #1513646: os.access on Windows now correctly determines write

1431
Tim Peters32a83612006-07-10 21:08:24 +00001432- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001433 Previously, the slight difference could cause compilation errors of the
1434 'zlib' module on systems with more than one version of zlib.
1435
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001436- The MSI compileall step was fixed to also support a TARGETDIR
1437 with spaces in it.

1455 documentation for the warnings module.
1456
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001457- Patch #1509163: MS Toolkit Compiler no longer available.

1468-----------------
1469
Georg Brandla56b9152006-06-19 06:35:54 +00001470- Patch #1507676: Error messages returned by invalid abstract object operations
1471 (such as iterating over an integer) have been improved and now include the
1472 type of the offending object to help with debugging.
1473
Brett Cannonea3912b2006-06-13 21:46:41 +00001474- Bug #992017: A classic class that defined a __coerce__() method that returned
1475 its arguments swapped would infinitely recurse and segfault the interpreter.
1476
Neal Norwitz909eb122006-06-12 02:13:21 +00001477- Fix the socket tests so they can be run concurrently.
1478
Neal Norwitzb9845e72006-06-12 02:11:18 +00001479- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001480 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001481
Brett Cannon22565aa2006-06-09 22:31:23 +00001482- Bug #532646: object.__call__() will continue looking for the __call__
1483 attribute on objects until one without one is found. This leads to recursion
1484 when you take a class and set its __call__ attribute to an instance of the
1485 class. Originally fixed for classic classes, but this fix is for new-style.
1486 Removes the infinite_rec_3 crasher.
1487
Georg Brandl24250812006-06-09 18:45:48 +00001488- The string and unicode methods startswith() and endswith() now accept
1489 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1490
Brett Cannonde3b0522006-06-08 17:00:45 +00001491- Buffer objects, at the C level, never used the char buffer
1492 implementation even when the char buffer for the wrapped object was
1493 explicitly requested (originally returned the read or write buffer).
1494 Now a TypeError is raised if the char buffer is not present but is
1495 requested.
1496
Georg Brandlddbaa662006-06-04 21:56:52 +00001497- Patch #1346214: Statements like "if 0: suite" are now again optimized
1498 away like they were in Python 2.4.
1499
Georg Brandlb7c8f542006-05-27 12:30:25 +00001500- Builtin exceptions are now full-blown new-style classes instead of
1501 instances pretending to be classes, which speeds up exception handling
1502 by about 80% in comparison to 2.5a2.
1503
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001504- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1505 Unicode 4.1.
1506
Georg Brandlf4ef1162006-05-26 18:03:31 +00001507- Patch #921466: sys.path_importer_cache is now used to cache valid and
1508 invalid file paths for the built-in import machinery which leads to
1509 fewer open calls on startup.
1510
Tim Peters696cf432006-05-24 21:10:40 +00001511- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1512 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1513 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1514 the number of input digits (it was and remains linear-time for bases
1515 2, 4, 8, 16 and 32).
1516
Tim Petersb713ec22006-05-23 18:45:30 +00001517- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1518 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1519 an integer close to ``sys.maxint``. This was repaired by patch
1520 #1335972, which also gives a nice speedup.
1521
Richard Jonescebbefc2006-05-23 18:28:17 +00001522- Patch #1337051: reduced size of frame objects.
1523
1524- PyErr_NewException now accepts a tuple of base classes as its
1525 "base" parameter.
1526
Richard Jones7c88dcc2006-05-23 10:37:38 +00001527- Patch #876206: function call speedup by retaining allocated frame
1528 objects.
1529
Georg Brandl7b90e162006-05-18 07:01:27 +00001530- Bug #1462152: file() now checks more thoroughly for invalid mode
1531 strings and removes a possible "U" before passing the mode to the
1532 C library function.
1533
Neal Norwitz1004a532006-05-15 07:17:23 +00001534- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1535
Neal Norwitz373f0a72006-05-15 07:04:36 +00001536- Bug #1487966: Fix SystemError with conditional expression in assignment
1537
Martin v. Löwis879768d2006-05-11 13:28:43 +00001538- WindowsError now has two error code attributes: errno, which carries
1539 the error values from errno.h, and winerror, which carries the error
1540 values from winerror.h. Previous versions put the winerror.h values
1541 (from GetLastError()) into the errno attribute.
1542
Martin v. Löwis77736712006-05-04 05:51:03 +00001543- Patch #1475845: Raise IndentationError for unexpected indent.
1544
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001545- Patch #1479181: split open() and file() from being aliases for each other.
1546
Tim Peters44bd9862006-06-01 13:49:23 +00001547- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1548 methods were always silently ignored by dictionaries when comparing keys.
1549 They are now passed through (except when using the C API function
1550 ``PyDict_GetItem()``, whose semantics did not change).
1551
1552- Bug #1456209: In some obscure cases it was possible for a class with a
1553 custom ``__eq__()`` method to confuse dict internals when class instances
1554 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1555 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001557Extension Modules
1558-----------------
1559
Trent Mick960a3f82006-06-28 20:30:41 +00001560- Bug #1295808: expat symbols should be namespaced in pyexpat
1561
1562- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1563
Brett Cannon6ee7d012006-06-08 16:23:04 +00001564- Change binascii.hexlify to accept a read-only buffer instead of only a char
1565 buffer and actually follow its documentation.
1566
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001567- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1568
Nick Coghlanc649ec52006-05-29 12:43:05 +00001569- Patch #1478788 (modified version): The functional extension module has
1570 been renamed to _functools and a functools Python wrapper module added.
1571 This provides a home for additional function related utilities that are
1572 not specifically about functional programming. See PEP 309.
1573
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001574- Patch #1493701: performance enhancements for struct module.
1575
Georg Brandl378d5922006-05-17 14:26:50 +00001576- Patch #1490224: time.altzone is now set correctly on Cygwin.
1577
Georg Brandl8d3342b2006-05-16 07:38:27 +00001578- Patch #1435422: zlib's compress and decompress objects now have a
1579 copy() method.
1580
Andrew MacIntyre92913322006-06-13 15:04:24 +00001581- Patch #1454481: thread stack size is now tunable at runtime for thread
1582 enabled builds on Windows and systems with Posix threads support.
1583
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001584- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1585 (up to the system limit of 32K characters).
1586
1587- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1588 As a result, these functions now raise WindowsError instead of OSError.
1589
Tim Peters7a822da2006-05-25 21:50:17 +00001590- ``time.clock()`` on Win64 should use the high-performance Windows
1591 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1592 Windows platforms).
1593
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001594- Calling Tk_Init twice is refused if the first call failed as that
1595 may deadlock.
1596
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001597- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1598 accept it without potentially using an uninitialized pointer.
1599
1600- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1601 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1602 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001603
Gregory P. Smith372b5832006-06-05 18:48:21 +00001604- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001605 [pybsddb project SF patch number 1466734]
1606
Gregory P. Smith372b5832006-06-05 18:48:21 +00001607- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1608 parameter is supplied. [SF pybsddb bug #1477863]
1609
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001610- bsddb: the __len__ method of a DB object has been fixed to return correct
1611 results. It could previously incorrectly return 0 in some cases.
1612 Fixes SF bug 1493322 (pybsddb bug 1184012).
1613
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001614- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1615 aborts the db transaction safely when a modifier callback fails.
1616 Fixes SF python patch/bug #1408584.
1617
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001618- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001619 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001620 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1621 database calls that would previously deadlock. [SF python bug #775414]
1622
Vinay Sajip28e57612006-07-01 10:45:20 +00001623- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001624
Walter Dörwald4994d952006-06-19 08:07:50 +00001625- Patch #1506645: add Python wrappers for the curses functions
1626 is_term_resized, resize_term and resizeterm.

1630
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001631- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1632 functions.
1633
Martin v. Löwis3798da02006-06-17 18:44:27 +00001634- Patch #812986: Update turtle output even if not tracing.
1635
Vinay Sajip28e57612006-07-01 10:45:20 +00001636- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001637 Tkinter.BaseWidget.
1638
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001639- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1640
Martin v. Löwis337487e2006-06-17 09:15:14 +00001641- Patch #763580: Add name and value arguments to Tkinter variable
1642 classes.
1643
Georg Brandl83cc0d02006-06-14 08:50:03 +00001644- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1645 mime.types file for determining MIME types.
1646
Georg Brandl2605ca82006-06-14 06:08:31 +00001647- Bug #1339007: Shelf objects now don't raise an exception in their
1648 __del__ method when initialization failed.
1649
Martin v. Löwisd8251432006-06-14 05:21:04 +00001650- Patch #1455898: The MBCS codec now supports the incremental mode for
1651 double-byte encodings.
1652
Tim Peters43898b42006-06-14 04:09:25 +00001653- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1654 guarantee that adjacent triples in the return list always describe
1655 non-adjacent blocks. Previously, a pair of matching blocks could end
1656 up being described by multiple adjacent triples that formed a partition
1657 of the matching pair.
1658
Greg Ward0e0c9f42006-06-11 16:24:11 +00001659- Bug #1498146: fix optparse to handle Unicode strings in option help,
1660 description, and epilog.
1661
Greg Wardd1c797e2006-06-11 14:42:41 +00001662- Bug #1366250: minor optparse documentation error.
1663
Greg Ward7f547402006-06-11 00:40:49 +00001664- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1665 clarify docs.
1666
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001667- The wsgiref package has been added to the standard library.
1668
Nick Coghlan676725d2006-06-08 13:54:49 +00001669- The functions update_wrapper() and wraps() have been added to the functools
1670 module. These make it easier to copy relevant metadata from the original
1671 function when writing wrapper functions.
1672
Tim Petersd6a9eef2006-06-05 01:48:21 +00001673- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1674 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001675
Martin v. Löwis3f767792006-06-04 19:36:28 +00001676- Patch #1359618: Speed up charmap encoder by using a trie structure
1677 for lookup.
1678
Tim Petersd609b1a2006-06-02 23:22:51 +00001679- The functions in the ``pprint`` module now sort dictionaries by key
1680 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1681 if and only if its display required more than one line, although that
1682 wasn't documented. The new behavior increases predictability; e.g.,
1683 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1684
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001685- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1686 (thanks for J. J. Lee).
1687
Georg Brandl2b330372006-05-28 20:23:12 +00001688- Patch #1496206: improve urllib2 handling of passwords with respect to
1689 default HTTP and HTTPS ports.
1690
George Yoshidaf3c65de2006-05-28 16:39:09 +00001691- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1692
Bob Ippolito7298f272006-05-23 18:43:47 +00001693- Patch #1281707: speed up gzip.readline.
1694
Georg Brandlb89316f2006-05-17 15:51:16 +00001695- Patch #1180296: Two new functions were added to the locale module:
1696 format_string() to get the effect of "format % items" but locale-aware,
1697 and currency() to format a monetary number with currency sign.
1698
Georg Brandle3a25832006-05-17 14:56:04 +00001699- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1700 and several features added, such as speed and geometry control.
1701
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001702- Patch #1488881: add support for external file objects in bz2 compressed
1703 tarfiles.
1704
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001705- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1706 stdout arguments, making it possible to redirect input and output
1707 for remote debugging.
1708
1709- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1710 a couple of issues, notably handling of long file names using the
1711 GNU LONGNAME extension.
1712
1713- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1714 new flag when ``name`` is already the name of an option flag.
1715
1716- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1717 package.
1718
1719- Patch #1472854: make the rlcompleter.Completer class usable on non-
1720 UNIX platforms.
1721
1722- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1723
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001724- Bug #1472827: correctly escape newlines and tabs in attribute values in
1725 the saxutils.XMLGenerator class.

1762
Thomas Heller1b046642006-04-18 18:51:06 +00001763- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1764 by converting these apis from macros into exported functions again:
1765
1766 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile

Martin v. Löwis45294a92006-04-18 06:24:08 +00001772- Under COUNT_ALLOCS, types are not necessarily immortal anymore.

Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001774- All uses of PyStructSequence_InitType have been changed to initialize
1775 the type objects only once, even if the interpreter is initialized
1776 multiple times.
1777
Neal Norwitz61546162006-04-14 05:20:28 +00001778- Bug #1454485, array.array('u') could crash the interpreter. This was
1779 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1780 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1781
1782- Py_UNICODE is unsigned. It was always documented as unsigned, but
1783 due to a bug had a signed value in previous versions.
1784
Tim Peters3a5e8b12006-04-11 01:44:07 +00001785- Patch #837242: ``id()`` of any Python object always gives a positive
1786 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1787 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001788 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001789 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001790
Tim Peters3a5e8b12006-04-11 01:44:07 +00001791 def __hash__(self):
1792 return id(self) # WRONG
1793
1794 because a hash result must be a (short) Python int but it was always
1795 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001796 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001797 was always usable as a hash value before this patch. That's no longer
1798 necessarily so.
1799
1800- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001801 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001802 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001803 #1454844)
1804
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001805- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1806 involving generators that have paused outside of any ``try`` or ``with``
1807 blocks. (In 2.5a1, a paused generator that was part of a reference
1808 cycle could not be garbage collected, regardless of whether it was
1809 paused in a ``try`` or ``with`` block.)

1816
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001817- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1818 fails with an error condition.
1819
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001820- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1821
1822- Bug #1117761: bsddb.*open() no longer raises an exception when using
1823 the cachesize parameter.
1824
1825- Bug #1149413: bsddb.*open() no longer raises an exception when using
1826 a temporary db (file=None) with the 'n' flag to truncate on open.
1827
1828- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1829 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001830
Armin Rigoa9017c32006-04-19 11:50:27 +00001831- Patch #1062014: AF_UNIX sockets under Linux have a special
1832 abstract namespace that is now fully supported.
1833

1835-------
1836
Peter Astrand7d1d4362006-07-14 14:04:45 +00001837- Bug #1223937: subprocess.CalledProcessError reports the exit status
1838 of the process using the returncode attribute, instead of
1839 abusing errno.
1840
Tim Peters711bf302006-04-25 03:31:36 +00001841- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1842 a doctest to be skipped (the code is not run, and the expected output
1843 or exception is ignored).
1844
Nick Coghlanda2268f2006-04-24 04:37:15 +00001845- Fixed contextlib.nested to cope with exceptions being raised and
1846 caught inside exit handlers.
1847
Greg Wardab05edc2006-04-23 03:47:58 +00001848- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1849 hex, octal, or binary; add ``append_const`` action; keep going if
1850 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1851 added ``epilog`` for better help generation).
1852
Tim Peters21fbd572006-04-21 21:18:10 +00001853- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1854 called from a thread spawned as a side effect of importing a module.
1855
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001856- The pydoc module now supports documenting packages contained in
1857 .zip or .egg files.
1858
1859- The pkgutil module now has several new utility functions, such
1860 as ``walk_packages()`` to support working with packages that are either
1861 in the filesystem or zip files.
1862
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001863- The mailbox module can now modify and delete messages from
1864 mailboxes, in addition to simply reading them. Thanks to Gregory
1865 K. Johnson for writing the code, and to the 2005 Google Summer of
1866 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001867
Tim Petersc7605f22006-04-17 21:12:33 +00001868- The ``__del__`` method of class ``local`` in module ``_threading_local``
1869 returned before accomplishing any of its intended cleanup.

1876
Anthony Baxtere29002c2006-04-12 12:07:31 +00001877- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1878 Windows. Bug #1469163.
1879
Phillip J. Eby47032112006-04-11 01:07:43 +00001880- The warnings, linecache, inspect, traceback, site, and doctest modules
1881 were updated to work correctly with modules imported from zipfiles or
1882 via other PEP 302 __loader__ objects.
1883
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001884- Patch #1467770: Reduce usage of subprocess._active to processes which
1885 the application hasn't waited on.

1890
Skip Montanaro262fb922006-04-21 02:31:07 +00001891- The pstats.Stats class accepts an optional stream keyword argument to
1892 direct output to an alternate file-like object.
1893
Anthony Baxter51bcb682006-04-05 14:51:42 +00001894Build
1895-----
1896
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001897- The Makefile now has a reindent target, which runs reindent.py on
1898 the library.
1899
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001900- Patch #1470875: Building Python with MS Free Compiler
1901
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001902- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001903
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001904- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1905 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001906 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001907 CXX from --with-cxx-main, see description in README.
1908
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001909- Patch #1429775: Link extension modules with the shared libpython.
1910
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001911- Fixed a libffi build problem on MIPS systems.
1912
Tim Peters8931ff12006-05-13 23:28:20 +00001913- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1914 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1915 and "%zu" for unsigned integers of type ``size_t``.
1916
Anthony Baxter51bcb682006-04-05 14:51:42 +00001917Tests
1918-----
1919
Nick Coghlanda2268f2006-04-24 04:37:15 +00001920- test_contextlib now checks contextlib.nested can cope with exceptions
1921 being raised and caught inside exit handlers.
1922
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001923- test_cmd_line now checks operation of the -m and -c command switches
1924
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001925- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1926 it separately and by hand. It also wasn't cleaning up its changes to
1927 the current Decimal context.
1928
Thomas Woutersabd08882006-04-26 15:53:30 +00001929- regrtest.py now has a -M option to run tests that test the new limits of
1930 containers, on 64-bit architectures. Running these tests is only sensible
1931 on 64-bit machines with more than two gigabytes of memory. The argument
1932 passed is the maximum amount of memory for the tests to use.

1941-------------
1942
Tim Petersb06d28c2006-05-12 01:57:59 +00001943- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1944
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001945- PEP 343: Added Context Types section to the library reference
1946 and attempted to bring other PEP 343 related documentation into
1947 line with the implementation and/or python-dev discussions.
1948
Tim Peters8dc73d22006-04-24 02:03:16 +00001949- Bug #1337990: clarified that ``doctest`` does not support examples
1950 requiring both expected output and an exception.

Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001957
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001958Core and builtins
1959-----------------
1960
Nick Coghlan43832302006-04-23 17:04:07 +00001961- PEP 338: -m command line switch now delegates to runpy.run_module
1962 allowing it to support modules in packages and zipfiles
1963
Martin v. Löwisc661b882006-04-20 04:54:23 +00001964- On Windows, .DLL is not an accepted file name extension for
1965 extension modules anymore; extensions are only found if they
1966 end in .PYD.
1967
Martin v. Löwisea62d252006-04-03 10:56:49 +00001968- Bug #1421664: sys.stderr.encoding is now set to the same value as
1969 sys.stdout.encoding.
1970
Neal Norwitz92e212f2006-04-03 04:48:37 +00001971- __import__ accepts keyword arguments.
1972
Georg Brandlccadf842006-03-31 18:54:53 +00001973- Patch #1460496: round() now accepts keyword arguments.
1974
Anthony Baxter262c00a2006-03-30 10:53:17 +00001975- Fixed bug #1459029 - unicode reprs were double-escaped.
1976
Hye-Shik Changd478f342006-03-23 12:32:36 +00001977- Patch #1396919: The system scope threads are reenabled on FreeBSD
1978 5.4 and later versions.
1979
Neal Norwitze98ccf62006-03-23 05:39:47 +00001980- Bug #1115379: Compiling a Unicode string with an encoding declaration
1981 now gives a SyntaxError.
1982
Georg Brandlabd1ff82006-03-18 07:59:59 +00001983- Previously, Python code had no easy way to access the contents of a
1984 cell object. Now, a ``cell_contents`` attribute has been added
1985 (closes patch #1170323).
1986
Tim Peterscf79aac2006-03-16 01:14:46 +00001987- Patch #1123430: Python's small-object allocator now returns an arena to
1988 the system ``free()`` when all memory within an arena becomes unused
1989 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1990 freed. Some applications will see a drop in virtual memory size now,
1991 especially long-running applications that, from time to time, temporarily
1992 use a large number of small objects. Note that when Python returns an
1993 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001994 platform C library will in turn return that memory to the operating system.
1995 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001996 appears to be effective at least on Microsoft C and gcc-based systems.
1997 Thanks to Evan Jones for hard work and patience.
1998
Georg Brandl533ff6f2006-03-08 18:09:27 +00001999- Patch #1434038: property() now uses the getter's docstring if there is
2000 no "doc" argument given. This makes it possible to legitimately use
2001 property() as a decorator to produce a read-only property.
2002
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002003- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2004 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2005 of requiring an int or long in slicing and a few other contexts, enabling
2006 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2007
Neal Norwitz995acdf2006-03-07 05:01:00 +00002008- Fixed various bugs reported by Coverity's Prevent tool.
2009
Brett Cannonbf364092006-03-01 04:25:17 +00002010- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2011 new exception base class, BaseException, which has a new message attribute.
2012 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2013 Raising a string exception now raises a DeprecationWarning.
2014
Thomas Woutersfb609f42006-02-28 16:37:25 +00002015- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2016 explicitly relative, using 'from .module import name' to mean 'from the same
2017 package as this module is in. Imports without dots still default to the
2018 old relative-then-absolute, unless 'from __future__ import
2019 absolute_import' is used.
2020
Brett Cannona7446e32006-02-27 23:39:10 +00002021- Properly check if 'warnings' raises an exception (usually when a filter set
2022 to "error" is triggered) when raising a warning for raising string
2023 exceptions.
2024
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002025- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002026 The name was removed from Include/code.h.
2027
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002028- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002029
Guido van Rossum1968ad32006-02-25 22:38:04 +00002030- Patch 1433928:
2031 - The copy module now "copies" function objects (as atomic objects).
2032 - dict.__getitem__ now looks for a __missing__ hook before raising
2033 KeyError.
2034
Tim Peters84ef21c2006-02-28 20:39:06 +00002035- PEP 343: with statement implemented. Needs ``from __future__ import
2036 with_statement``. Use of 'with' as a variable will generate a warning.
2037 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002038 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002039 The following objects have __context__ methods:
2040 - The built-in file type.
2041 - The thread.LockType type.
2042 - The following types defined by the threading module:
2043 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2044 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002045
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002046- Fix the encodings package codec search function to only search
2047 inside its own package. Fixes problem reported in patch #1433198.
2048
2049 Note: Codec packages should implement and register their own
2050 codec search function. PEP 100 has the details.
2051
Tim Peters9ea89d22006-06-04 03:26:02 +00002052- PEP 353: Using ``Py_ssize_t`` as the index type.
2053
2054- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2055 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2056 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2057 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2058 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002059
Neal Norwitzfc76d632006-01-10 06:03:13 +00002060- Patch #1400181, fix unicode string formatting to not use the locale.
2061 This is how string objects work. u'%f' could use , instead of .
2062 for the decimal point. Now both strings and unicode always use periods.
2063
Neal Norwitz671b9e32006-01-09 07:07:12 +00002064- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2065 configure would break checking curses.h.
2066
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002067- Bug #959576: The pwd module is now builtin. This allows Python to be
2068 built on UNIX platforms without $HOME set.
2069
Neal Norwitzc10978f2005-12-19 06:07:16 +00002070- Bug #1072182, fix some potential problems if characters are signed.
2071
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002072- Bug #889500, fix line number on SyntaxWarning for global declarations.
2073
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002074- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2075
Neal Norwitze7214a12005-12-18 05:03:17 +00002076- Support for converting hex strings to floats no longer works.
2077 This was not portable. float('0x3') now raises a ValueError.
2078
Barry Warsaw2a38a862005-12-18 01:27:35 +00002079- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002080 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002081 is now displayed in interactive prompt banner.
2082
Georg Brandlfa166682005-12-17 21:45:17 +00002083- Implementation of PEP 341 - Unification of try/except and try/finally.
2084 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002085 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002086
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002087- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2088 now encodes backslash correctly.
2089
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002090- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2091
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002092- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002093 and long longs.
2094
Neal Norwitz67715f02005-11-09 06:59:35 +00002095- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002096 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002097 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002098
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002099- Replaced most Unicode charmap codecs with new ones using the
2100 new Unicode translate string feature in the builtin charmap
2101 codec; the codecs were created from the mapping tables available
2102 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2103 encodings now include a mapping for the Apple logo)
2104
Tim Peterse3547fd2005-12-16 23:13:57 +00002105- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002106
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002107- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002108
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002109- A new AST parser implementation was completed. The abstract
2110 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002111 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002112
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002113- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002114 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2115
Neal Norwitz708e51a2005-10-03 04:48:15 +00002116- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2117
Neal Norwitz11bd1192005-10-03 00:54:56 +00002118- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2119 Provide a warning when a directory is passed on the command line.
2120
Neal Norwitz40d37812005-10-02 01:48:49 +00002121- Fix segfault with invalid coding.
2122
2123- SF bug #772896: unknown encoding results in MemoryError.
2124
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002125- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002126 supported a __len__() method which evaluated to False when the iterator
2127 was empty.
2128
Guido van Rossum630db602005-09-20 18:49:54 +00002129- On 64-bit platforms, when __len__() returns a value that cannot be
2130 represented as a C int, raise OverflowError.
2131
Skip Montanarof8948ca2005-09-19 03:54:46 +00002132- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002133 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002134
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002135- SF bug #893549: parsing keyword arguments was broken with a few format
2136 codes.
2137
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002138- Changes donated by Elemental Security to make it work on AIX 5.3
2139 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2140 bug #105470: test_pwd fails on 64bit system (Opteron).
2141
Guido van Rossum539c6622005-09-14 17:49:54 +00002142- Changes donated by Elemental Security to make it work on HP-UX 11 on
2143 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2144
Georg Brandl4550b8d2005-08-26 06:43:52 +00002145- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002146 (fixes bug #1119418).
2147
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002148- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2149
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002150- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2151 exceptions that cause a function to exit.
2152
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002153- The implementation of set() and frozenset() was revised to use its
2154 own internal data structure. Memory consumption is reduced by 1/3
2155 and there are modest speed-ups as well. The API is unchanged.
2156
Tim Petersde7990b2005-07-17 23:45:23 +00002157- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2158
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002159- SF bug #1229429: PyObject_CallMethod failed to decrement some
2160 reference counts in some error exit cases.
2161
Tim Petersecc6e6a2005-07-10 22:30:55 +00002162- SF bug #1185883: Python's small-object memory allocator took over
2163 a block managed by the platform C library whenever a realloc specified
2164 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002165 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002166 portable way to copy data from the C-managed block into Python's
2167 small-object space without risking a memory fault. Python's small-object
2168 realloc now leaves such blocks under the control of the platform C
2169 realloc.
2170
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002171- SF bug #1232517: An overflow error was not detected properly when
2172 attempting to convert a large float to an int in os.utime().
2173
Raymond Hettinger3296e692005-06-29 23:29:56 +00002174- SF bug #1224347: hex longs now print with lowercase letters just
2175 like their int counterparts.
2176
Michael W. Hudson188d4362005-06-20 16:52:57 +00002177- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2178 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2179 interpreter states; back out that fix and do a better job (see
2180 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2181 for a longer write-up of the problem).
2182
Michael W. Hudsondf888462005-06-03 14:41:55 +00002183- SF patch #1180995: marshal now uses a binary format by default when
2184 serializing floats.
2185
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002186- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2187 the routines that promise to produce IEEE 754 binary representations
2188 of floats now simply copy bytes around.
2189
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002190- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2191 278.
2192
Brett Cannonc3647ac2005-04-26 03:45:26 +00002193- patch #1109424: int, long, float, complex, and unicode now check for the
2194 proper magic slot for type conversions when subclassed. Previously the
2195 magic slot was ignored during conversion. Semantics now match the way
2196 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002197 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002198 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002199 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002200
Barry Warsawc8d907c2005-04-19 23:43:40 +00002201- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2202 NULL, now raise an AttributeError when attempting to set or delete the
2203 attribute. Previously a TypeError was raised, but this was inconsistent
2204 with the equivalent pure-Python implementation.
2205
Michael W. Hudson774479c2005-04-18 08:46:17 +00002206- It is now safe to call PyGILState_Release() before
2207 PyEval_InitThreads() (note that if there is reason to believe there
2208 are multiple threads around you still must call PyEval_InitThreads()
2209 before using the Python API; this fix is for extension modules that
2210 have no way of knowing if Python is multi-threaded yet).
2211
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002212- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2213 disabled caused a crash.
2214
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002215- Bug #1165306: instancemethod_new allowed the creation of a method
2216 with im_class == im_self == NULL, which caused a crash when called.
2217
Tim Petersecc6e6a2005-07-10 22:30:55 +00002218- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002219 fixes the crash seen in bug #1165761
2220
Raymond Hettinger96229b12005-03-11 06:49:40 +00002221- Added two new builtins, any() and all().
2222
Brett Cannon409d8f22005-03-05 06:47:57 +00002223- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002224 (e.g., ``class C(): pass`` is no longer a syntax error).
2225 Patch #1176012 added support to the 'parser' module and 'compiler' package
2226 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002227
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002228- Patch #1115086: Support PY_LONGLONG in structmember.
2229
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002230- Bug #1155938: new style classes did not check that __init__() was
2231 returning None.
2232
Tim Petersecc6e6a2005-07-10 22:30:55 +00002233- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002234 ('\') with a specific error message.
2235
Martin v. Löwisff232d72005-03-03 09:24:38 +00002236- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2237
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002238- Bug #1124295: the __name__ attribute of file objects was
2239 inadvertently made inaccessible in restricted mode.
2240
Tim Petersecc6e6a2005-07-10 22:30:55 +00002241- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002242 an ferror() call.
2243
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002244- min() and max() now support key= arguments with the same meaning as in
2245 list.sort().
2246
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002247- The peephole optimizer now performs simple constant folding in expressions:
2248 (2+3) --> (5).
2249
Raymond Hettingera422c342005-01-11 03:03:27 +00002250- set and frozenset objects can now be marshalled. SF #1098985.
2251
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002252- Bug #1077106: Poor argument checking could cause memory corruption
2253 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002254
Jeremy Hyltonab630502005-02-04 18:44:06 +00002255- The parser did not complain about future statements in illegal
2256 positions. It once again reports a syntax error if a future
2257 statement occurs after anything other than a doc string.
2258
Neil Schemenauercf52c072005-08-12 17:34:58 +00002259- Change the %s format specifier for str objects so that it returns a
2260 unicode instance if the argument is not an instance of basestring and
2261 calling __str__ on the argument returns a unicode instance.
2262
Tim Petersf4e69282006-02-27 17:15:31 +00002263- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2264 current thread state when the auto-GIL-state machinery knows about
2265 it (since the thread state is being deleted, continuing to remember it
2266 can't help, but can hurt if another thread happens to get created with
2267 the same thread id).
2268
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002269Extension Modules
2270-----------------
2271
Georg Brandl43f08a82006-03-31 18:01:16 +00002272- Patch #1380952: fix SSL objects timing out on consecutive read()s

2275
Anthony Baxterfa869072006-03-20 05:21:58 +00002276- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
2277 In addition, the existing ulaw code was updated.
2278
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002279- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00002280 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002281
Neal Norwitz10be10c2006-03-16 06:50:13 +00002282- Everything under lib-old was removed. This includes the following modules:
2283 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00002284 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00002285 util, whatsound, whrandom, zmod
2286
2287- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2288
2289- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002290 is deprecated. The undocumented re.engine variable no longer exists.
2291
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002292- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2293 SS2 (single-shift 2) escape sequences correctly.
2294
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002295- The unicodedata module was updated to the 4.1 version of the Unicode
2296 database. The 3.2 version is still available as unicodedata.db_3_2_0
2297 for applications that require this specific version (such as IDNA).
2298
Neal Norwitzb62c4332006-03-04 18:35:47 +00002299- The timing module is no longer built by default. It was deprecated
2300 in PEP 4 in Python 2.0 or earlier.
2301
Guido van Rossum1968ad32006-02-25 22:38:04 +00002302- Patch 1433928: Added a new type, defaultdict, to the collections module.
2303 This uses the new __missing__ hook behavior added to dict (see above).
2304
Georg Brandldbd83392006-02-20 09:42:33 +00002305- Bug #854823: socketmodule now builds on Sun platforms even when
2306 INET_ADDRSTRLEN is not defined.
2307
Georg Brandlf4f44152006-02-18 22:29:33 +00002308- Patch #1393157: os.startfile() now has an optional argument to specify
2309 a "command verb" to invoke on the file.
2310
Neal Norwitz082b2df2006-02-07 07:04:46 +00002311- Bug #876637, prevent stack corruption when socket descriptor
2312 is larger than FD_SETSIZE.
2313
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00002314- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
2315 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
2316 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
2317
Martin v. Löwis57a34e82006-02-04 19:12:37 +00002318- Patch #1422385: The nis module now supports access to domains other
2319 than the system default domain.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002459- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2460 been renamed to have only a single underscore prefix. This was done to
2461 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002462
Nick Coghlan43832302006-04-23 17:04:07 +00002463- PEP 338: new module runpy defines a run_module function to support
2464 executing modules which provide access to source code or a code object
2465 via the PEP 302 import mechanisms.
2466
Anthony Baxter93f5b932006-04-03 08:05:07 +00002467- The email module's parsedate_tz function now sets the daylight savings

2475 in attribute values.
2476
Anthony Baxterc51ee692006-04-01 00:57:31 +00002477- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002478 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002479 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002480 module will not be built.
2481
Tim Petersc17976e2006-04-01 00:26:53 +00002482- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2483 aren't officially supported here, and trying to use them will probably
2484 raise an exception some day. But dicts have been allowed, and "mostly
2485 worked", so support for them won't go away without warning.
2486
Georg Brandl338ef7d2006-03-31 18:42:16 +00002487- Bug #1445068: getpass.getpass() can now be given an explicit stream

2505
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002506- email 4.0 package now integrated. This is largely the same as the email 3.0
2507 package that was included in Python 2.3, except that PEP 8 module names are
2508 now used (e.g. mail.message instead of email.Message). The MIME classes
2509 have been moved to a subpackage (e.g. email.mime.text instead of
2510 email.MIMEText). The old names are still supported for now. Several
2511 deprecated Message methods have been removed and lots of bugs have been
2512 fixed. More details can be found in the email package documentation.
2513
Walter Dörwald40108c92006-03-27 08:15:44 +00002514- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2515 (a subclass of tuple) that provides incremental decoders and encoders
2516 (a way to use stateful codecs without the stream API). Python functions
2517 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2518 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2519 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00002521- Patch #1359365: Calling next() on a closed StringIO.String object raises
2522 a ValueError instead of a StopIteration now (like file and cString.String do).
2523 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2524 called before (like file and StringIO.StringIO do).

Georg Brandl4edd9892006-01-13 16:59:46 +00002586- Bug #1403410: The warnings module now doesn't get confused
2587 when it can't find out the module name it generates a warning for.
Georg Brandlb709c2c2006-01-20 09:07:35 +00002588

2592
Neal Norwitz338e7862005-12-23 21:27:46 +00002593- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
2594 LoadError as documented, instead of IOError. For compatibility,
2595 LoadError subclasses IOError.
2596
Brett Cannon3cbd0382005-12-16 22:49:23 +00002597- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00002598 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2599 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2600 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2601 Ronald L. Rivest offered this advice for Python:
2602
2603 "The consensus of researchers in this area (at least as
2604 expressed at the NIST Hash Function Workshop 10/31/05),
2605 is that SHA-256 is a good choice for the time being, but
2606 that research should continue, and other alternatives may
2607 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002608
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002609- Added a subset of Fredrik Lundh's ElementTree package. Available

2662 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002663 correct line numbers for decoding errors in source code.

2702 Bug #1224621.
2703
Raymond Hettinger68c04532005-06-10 11:05:19 +00002704- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002705 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002706 the generate_tokens() function now accepts a callable argument that
2707 terminates by raising StopIteration.
2708
Georg Brandl9166e1a2005-06-04 09:20:03 +00002709- Bug #1196315: fix weakref.WeakValueDictionary constructor.

2713
Skip Montanaro174dd222005-05-14 20:54:16 +00002714- Patch #1120353: The xmlrpclib module provides better, more transparent,

2717 class at all.
2718
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002719- distutils.commands.upload was added to support uploading distribution

2723 them to PyPI.
2724
Raymond Hettinger267b8682005-03-27 10:47:39 +00002725- decimal operator and comparison methods now return NotImplemented
2726 instead of raising a TypeError when interacting with other types. This
2727 allows other classes to implement __radd__ style methods and have them
2728 work as expected.
2729
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002730- Bug #1163325: Decimal infinities failed to hash. Attempting to
2731 hash a NaN raised an InvalidOperation instead of a TypeError.
2732
Tim Petersecc6e6a2005-07-10 22:30:55 +00002733- Patch #918101: Add tarfile open mode r|* for auto-detection of the

2767
Guido van Rossumd0641422005-02-03 15:01:24 +00002768- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2769 disables recursive traversal through instance attributes, which can
2770 be exploited in various ways.
2771
Tim Peterse3547fd2005-12-16 23:13:57 +00002772- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002773 flags on the HTTP listening socket.
2774

Thomas Hellerd6c6e222005-01-20 19:20:16 +00002783- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2784
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002785- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2786
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002787- Enhancements to the csv module:
2788
2789 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002790 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002791 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002792 + Dialect parameter parsing has been re-implemented to improve error
2793 reporting.
2794 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2795 dictates.
2796 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002797 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002798 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002799 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2800 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002801 + reader now allows \r characters to be quoted (previously it only allowed
2802 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002803 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002804 + Dialect classes passed to the module are no longer instantiated by
2805 the module before being parsed (the former validation scheme required
2806 this, but the mechanism was unreliable).
2807 + The dialect registry now contains instances of the internal
2808 C-coded dialect type, rather than references to python objects.
2809 + the internal c-coded dialect type is now immutable.
2810 + register_dialect now accepts the same keyword dialect specifications
2811 as the reader and writer, allowing the user to register dialects
2812 without first creating a dialect class.
2813 + a configurable limit to the size of parsed fields has been added -
2814 previously, an unmatched quote character could result in the entire
2815 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002816 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002817 the parser field size limit (returning the former limit). The initial
2818 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002819 + A line_num attribute has been added to the reader object, which tracks
2820 the number of lines read from the source iterator. This is not
2821 the same as the number of records returned, as records can span
2822 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002823 + reader and writer objects were not being registered with the cyclic-GC.
2824 This has been fixed.
2825
Brett Cannone6539c42005-01-08 02:43:53 +00002826- _DummyThread objects in the threading module now delete self.__block that is
2827 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2828 lock primitives tend to be limited in number and thus should not be wasted on
2829 a _DummyThread object. Fixes bug #1089632.
2830
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002831- The imghdr module now detects Exif files.
2832
Raymond Hettinger6065d322004-12-20 23:51:53 +00002833- StringIO.truncate() now correctly adjusts the size attribute.
2834 (Bug #951915).
2835
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002836- locale.py now uses an updated locale alias table (built using
2837 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2838 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002839 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002840
Raymond Hettinger3557f422004-12-07 12:02:02 +00002841- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2842
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002843- the pickle module no longer accepts the deprecated None option in the
2844 args tuple returned by __reduce__().
2845
Brett Cannon84667c02004-12-07 03:25:18 +00002846- optparse now optionally imports gettext. This allows its use in setup.py.
2847
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002848- the pickle module no longer uses the deprecated bin parameter.
2849

2855
Raymond Hettinger664347b2004-12-04 21:21:53 +00002856- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2857 extended or overridden by subclasses. Formerly, the subclassed method would
2858 be ignored by the rest of the module. (Bug #1078905).
2859
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002860- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002861 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002862
Walter Dörwald36733692004-12-22 12:50:50 +00002863- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2864 once when a size argument is given. This prevents a buffer overflow in the
2865 tokenizer with very long source lines.
2866
Barry Warsaw538561e2006-01-01 21:48:54 +00002867- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2868 immediately after creating the object, without any intervening
2869 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002870
Skip Montanaro05885812005-01-16 20:48:27 +00002871- The reconvert.quote function can now emit triple-quoted strings. The
2872 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002873
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002874- ``UserString.MutableString`` now supports negative indices in
2875 ``__setitem__`` and ``__delitem__``
2876
Greg Ward40407942005-03-05 02:53:17 +00002877- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2878 correctly.
2879
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002880- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2881 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2882 character even if the user has passed a size parameter to get a proper
2883 line ending. Remove the special handling of a "\r\n" that has been split
2884 between two lines.
2885
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002886- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2887 about illegal code points. The codec now supports PEP 293 style error
2888 handlers.
2889
Walter Dörwald78a78b02005-09-01 12:04:29 +00002890- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002891 from the input stream, so that the output is a byte string in the correct
2892 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002893
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002894- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2895 considering it exactly like a '*'.
2896
Walter Dörwald007f8df2005-10-09 19:42:27 +00002897- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2898 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002899
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002900- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2901
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002902- Patch #1413711: Certain patterns of differences were making difflib
2903 touch the recursion limit.
2904
Walter Dörwald58917a62006-03-31 15:26:22 +00002905- Bug #947906: An object oriented interface has been added to the calendar
2906 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002907 called as a script (e.g. via ``python -mcalendar``). Localized month and
2908 weekday names can be ouput (even if an exotic encoding is used) using
2909 special classes that use unicode.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002911Build
2912-----
2913
Neal Norwitz602d3392006-03-31 08:21:40 +00002914- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2915 by using -mieee gcc option.
2916

2918
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002919- Build support for Win64-AMD64 was added.
2920
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002921- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2922
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002923- Patch #881820: look for openpty and forkpty also in libbsd.
2924
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002925- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2926 The zlib module is now builtin on Windows.
2927
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002928- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2929
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002930- Bug #1189330: configure did not correctly determine the necessary
2931 value of LINKCC if python was built with GCC 4.0.
2932
Trent Mick8321b422005-07-26 02:29:21 +00002933- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2934 vulnerability in zlib 1.2.1 and 1.2.2.
2935
Brett Cannon08cd5982005-04-24 22:26:38 +00002936- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2937 flags that change binary compatibility. Changes were also made to
2938 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002939 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002940
Bob Ippolitoed233462005-03-29 13:47:59 +00002941- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2942 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2943 no longer exists). This configure patch makes things right.
2944
Martin v. Löwise2713be2005-03-08 15:03:08 +00002945- Bug #1158607: Build with --disable-unicode again.
2946
Brett Cannon46d96232005-02-16 00:07:19 +00002947- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2948 defined. Discovered as a result of not being able to build on OS X.
2949
Brett Cannon516592f2004-12-07 00:42:59 +00002950- setup.py now uses the directories specified in LDFLAGS using the -L option
2951 and in CPPFLAGS using the -I option for adding library and include
2952 directories, respectively, for compiling extension modules against. This has
2953 led to the core being compiled using the values in CPPFLAGS. It also removes
2954 the need for the special-casing of both DarwinPorts and Fink for darwin since
2955 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2956 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2957 Fink, ``-I/opt/local/include`` for DarwinPorts).
2958
Brett Cannon43802422005-02-10 20:48:03 +00002959- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2960 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2961 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2962 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002964C API
2965-----
2966
Tim Petersc9d78aa2006-03-26 23:27:58 +00002967- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2968 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2969 is obtained via the ``PyObject_`` family, it must be released via the
2970 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2971 always been officially true, but when Python's small-object allocator was
2972 introduced, an attempt was made to cater to a few extension modules
2973 discovered at the time that obtained memory via ``PyObject_New`` but
2974 released it via ``PyMem_DEL``. It's years later, and if such code still
2975 exists it will fail now (probably with segfaults, but calling wrong
2976 low-level memory management functions can yield many symptoms).
2977
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002978- Added a C API for set and frozenset objects.
2979
Raymond Hettinger66517482004-12-03 11:45:13 +00002980- Removed PyRange_New().
2981
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002982- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2983 mapping argument now. This string is used as a mapping table. Byte values
2984 greater than the length of the string and 0xFFFE are treated as undefined
2985 mappings.

Martin v. Löwis4d394df2005-01-23 09:19:22 +00002991- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002992
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002993- Patch #1276356: New resource "urlfetch" is implemented. This enables
2994 even impatient people to run tests that require remote files.
