Nick Coghlanbb0996c2006-09-03 01:20:46 +00007What's New in Python 2.6 alpha 1?
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
Neal Norwitz0ac60192007-05-27 04:08:54 +000015- Add new attribute names for function objects. All the func_* become
16 __*__ attributes. (Some already existed, e.g., __doc__ and __name__.)
17
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +000018- Add -3 option to the interpreter to warn about features that are
19 deprecated and will be changed/removed in Python 3.0.
20
Georg Brandl2134e752007-05-21 20:34:16 +000021- Patch #1686487: you can now pass any mapping after '**' in function
22 calls.
23
Collin Winter62903052007-05-18 23:11:24 +000024- except clauses may now be spelled either "except E, target:" or
25 "except E as target:". This is to provide forwards compatibility with
26 Python 3.0.
27
Brett Cannon229cee22007-05-05 01:34:02 +000028- Deprecate BaseException.message as per PEP 352.
29
Armin Rigo9790a272007-05-02 19:23:31 +000030- Bug #1303614: don't expose object's __dict__ when the dict is
31 inherited from a builtin base.
32
Vinay Sajip8549ce32007-05-06 17:53:37 +000033- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +000034 setting a plain string, ie don't expand to single letter identifiers.
35
Raymond Hettinger13936692007-04-11 18:40:58 +000036- Request #1191699: Slices can now be pickled.
37
Raymond Hettinger4db5fe92007-04-12 04:10:00 +000038- Request #1193128: str.translate() now allows a None argument for
39 translations that only remove characters without re-mapping the
40 remaining characters.
41
Georg Brandl5cb76c12007-03-21 09:00:39 +000042- Patch #1682205: a TypeError while unpacking an iterable is no longer
43 masked by a generic one with the message "unpack non-sequence".
44
Neal Norwitzaa754b72007-03-21 06:39:48 +000045- Remove unused file Python/fmod.c.
46
Guido van Rossum143b5642007-03-23 04:58:42 +000047- Bug #1683368: The object.__init__() and object.__new__() methods are
48 now stricter in rejecting excess arguments. The only time when
49 either allows excess arguments is when it is not overridden and the
50 other one is. For backwards compatibility, when both are
51 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +000052 warning later). Also, type.__init__() insists on the same signature
53 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +000054
Georg Brandl2b869942007-03-17 16:08:45 +000055- Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
56 to complex using its __complex__() method before falling back to the
57 __float__() method. Therefore, the functions in the cmath module now
58 can operate on objects that define a __complex__() method.
59
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +000060- Patch #1623563: allow __class__ assignment for classes with __slots__.
61 The old and the new class are still required to have the same slot names.
62
Collin Winter77c67bd2007-03-16 04:11:30 +000063- Patch #1642547: Fix an error/crash when encountering syntax errors in
64 complex if statements.
65
Žiga Seilnacht20f43d32007-03-15 11:44:55 +000066- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
67 is called with an object that is faking its type.
68
Žiga Seilnacht71436f02007-03-14 12:24:09 +000069- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
70 name.
71
Georg Brandl5240d742007-03-13 20:46:32 +000072- Patch #1444529: the builtin compile() now accepts keyword arguments.
73
Georg Brandl7b9c5552007-03-12 14:30:05 +000074- Bug #1678647: write a newline after printing an exception in any
75 case, even when converting the value to a string failed.
76
Georg Brandl871f1bc2007-03-12 13:17:36 +000077- The dir() function has been extended to call the __dir__() method on
78 its argument, if it exists. If not, it will work like before. This allows
79 customizing the output of dir() in the presence of a __getattr__().
80
Collin Winter276887b2007-03-12 16:11:39 +000081- Patch #922167: Python no longer segfaults when faced with infinitely
82 self-recursive reload() calls (as reported by bug #742342).
83
Žiga Seilnacht89032082007-03-11 15:54:54 +000084- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
85
Collin Wintere38051d2007-03-09 20:33:07 +000086- Patch #1491866: change the complex() constructor to allow parthensized
87 forms. This means complex(repr(x)) now works instead of raising a
88 ValueError.
89
Georg Brandlaa2321b2007-03-07 00:40:28 +000090- Patch #703779: unset __file__ in __main__ after running a file. This
91 makes the filenames the warning module prints much more sensible when
92 a PYTHONSTARTUP file is used.
93
Georg Brandl49aafc92007-03-07 00:34:46 +000094- Variant of patch #697613: don't exit the interpreter on a SystemExit
95 exception if the -i command line option or PYTHONINSPECT environment
96 variable is given, but break into the interactive interpreter just like
97 on other exceptions or normal program exit.
98
Georg Brandl00cd8182007-03-06 18:41:12 +000099- Patch #1638879: don't accept strings with embedded NUL bytes in long().
100
Georg Brandl098cd692007-03-06 12:17:50 +0000101- Bug #1674503: close the file opened by execfile() in an error condition.
102
Georg Brandl0fca97a2007-03-05 22:28:08 +0000103- Patch #1674228: when assigning a slice (old-style), check for the
104 sq_ass_slice instead of the sq_slice slot.
105
Neal Norwitz88516a62007-02-26 22:41:45 +0000106- When printing an unraisable error, don't print exceptions. before the name.
107 This duplicates the behavior whening normally printing exceptions.
108
Martin v. Löwisfd963262007-02-09 12:19:32 +0000109- Bug #1653736: Properly discard third argument to slot_nb_inplace_power.
110
Brett Cannon129bd522007-01-30 21:34:36 +0000111- PEP 352: Raising a string exception now triggers a TypeError. Attempting to
112 catch a string exception raises DeprecationWarning.
113
Brett Cannonf5bee302007-01-23 23:21:22 +0000114- Bug #1377858: Fix the segfaulting of the interpreter when an object created
115 a weakref on itself during a __del__ call for new-style classes (classic
116 classes still have the bug).
117
Martin v. Löwis6c5c5022007-01-23 21:11:47 +0000118- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
119 frame's thread state.
120
Thomas Wouters6ed19652007-01-23 13:50:49 +0000121- patch #1630975: Fix crash when replacing sys.stdout in sitecustomize.py
122
Martin v. Löwis4885e7d2007-01-19 06:42:22 +0000123- Bug #1637022: Prefix AST symbols with _Py_.
124
Neal Norwitz72cd02c2007-01-05 05:25:22 +0000125- Prevent seg fault on shutdown which could occur if an object
126 raised a warning.
127
Martin v. Löwis7b7c9d42007-01-04 21:06:12 +0000128- Bug #1566280: Explicitly invoke threading._shutdown from Py_Main,
129 to avoid relying on atexit.
130
Raymond Hettinger94547f72006-12-20 06:42:06 +0000131- Bug #1590891: random.randrange don't return correct value for big number
132

Georg Brandlb9f4ad32006-10-29 18:31:42 +0000142- Bug #1576657: when setting a KeyError for a tuple key, make sure that
143 the tuple isn't used as the "exception arguments tuple".
144
Neal Norwitz21997af2006-10-28 21:19:07 +0000145- Bug #1565514, SystemError not raised on too many nested blocks.
146
Thomas Hellerdf08f0b2006-10-27 18:31:36 +0000147- Bug #1576174: WindowsError now displays the windows error code
148 again, no longer the posix error code.
149
Martin v. Löwisb5bc5372006-10-27 06:16:31 +0000150- Patch #1549049: Support long values in structmember, issue warnings
151 if the assigned value for structmember fields gets truncated.
152
Neal Norwitzcbeb6872006-10-14 21:33:38 +0000153- Update the peephole optimizer to remove more dead code (jumps after returns)
154 and inline unconditional jumps to returns.
155
Georg Brandl2c1375c2006-10-12 11:27:59 +0000156- Bug #1545497: when given an explicit base, int() did ignore NULs
157 embedded in the string to convert.
158
Georg Brandl846f73a2006-10-08 07:11:54 +0000159- Bug #1569998: break inside a try statement (outside a loop) is now
160 recognized and rejected.
161
Armin Rigo7ccbca92006-10-04 12:17:45 +0000162- list.pop(x) accepts any object x following the __index__ protocol.
163
164- Fix some leftovers from the conversion from int to Py_ssize_t
165 (relevant to strings and sequences of more than 2**31 items).
166
167- A number of places, including integer negation and absolute value,
168 were fixed to not rely on undefined behaviour of the C compiler
169 anymore.
Martin v. Löwis820d6ac2006-10-04 05:47:34 +0000170

Georg Brandla10d3af2006-09-24 12:35:36 +0000178- Fix a bug in the parser's future statement handling that led to "with"

187
Brett Cannon9adeab72006-09-20 18:34:28 +0000188- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This

190
Georg Brandlec6c2df2006-09-11 09:38:35 +0000191- Make _PyGILState_NoteThreadState() static, it was not used anywhere

200
Tim Petersc10c9d02006-09-05 02:18:09 +0000201- Overflow checking code in integer division ran afoul of new gcc
202 optimizations. Changed to be more standard-conforming.

209 head is the original string if sep was not found.
210
Neal Norwitzdac090d2006-09-05 03:53:08 +0000211- Bug #1520864: unpacking singleton tuples in list comprehensions and
212 generator expressions (x for x, in ... ) works again. Fixing this problem

925-----------------
926
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000927- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000928 compared equal or unequal to a string and a UnicodeDecodeError
929 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000930
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000931 Instead, the equal (==) and unequal (!=) comparison operators will
932 now issue a UnicodeWarning and interpret the two objects as
933 unequal. The UnicodeWarning can be filtered as desired using
934 the warning framework, e.g. silenced completely, turned into an
935 exception, logged, etc.
936
937 Note that compare operators other than equal and unequal will still
938 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000939
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000940- Fix segfault when doing string formatting on subclasses of long.
941
942- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
943 with new-style classes.
944
945- Fix bug related to __len__ functions returning negative values with
946 classic classes.
947
948- Patch #1538606, Fix __index__() clipping. There were some problems
949 discovered with the API and how integers that didn't fit into Py_ssize_t
950 were handled. This patch attempts to provide enough alternatives
951 to effectively use __index__.
952
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000953- Bug #1536021: __hash__ may now return long int; the final hash
954 value is obtained by invoking hash on the long int.
955
Thomas Hellerab1049c2006-08-08 17:37:00 +0000956- Bug #1536786: buffer comparison could emit a RuntimeWarning.
957
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000958- Bug #1535165: fixed a segfault in input() and raw_input() when
959 sys.stdin is closed.
960
Thomas Heller74d36f02006-08-04 18:17:40 +0000961- On Windows, the PyErr_Warn function is now exported from
962 the Python dll again.
963
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000964- Bug #1191458: tracing over for loops now produces a line event
965 on each iteration. Fixing this problem required changing the .pyc
966 magic number. This means that .pyc files generated before 2.5c1
967 will be regenerated.
968
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000969- Bug #1333982: string/number constants were inappropriately stored
970 in the byte code and co_consts even if they were not used, ie
971 immediately popped off the stack.
972
Georg Brandle9462c72006-08-04 18:03:37 +0000973- Fixed a reference-counting problem in property().

976Library
977-------
978
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000979- Fix a bug in the ``compiler`` package that caused invalid code to be
980 generated for generator expressions.
981
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000982- The distutils version has been changed to 2.5.0. The change to
983 keep it programmatically in sync with the Python version running
984 the code (introduced in 2.5b3) has been reverted. It will continue
985 to be maintained manually as static string literal.
986
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000987- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000988 and this cannot be converted to the required C type, an exception is
989 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000990 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000991
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000992- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000993 an exception.
994
Tim Petersc10c9d02006-09-05 02:18:09 +0000995- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000996 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000997 workarounds for clocks with low resolution, to stop the code yielding
998 duplicate UUIDs.
999
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001000- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1001 before raising SystemExit, allowing IDLE to honor quit() and exit().
1002
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001003- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1004
Georg Brandl7a1af772006-08-14 21:55:28 +00001005- Patch #1536071: trace.py should now find the full module name of a
1006 file correctly even on Windows.
1007
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001008- logging's atexit hook now runs even if the rest of the module has
1009 already been cleaned up.
1010
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001011- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001012
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001013- Bug #1531405, format_exception no longer raises an exception if
1014 str(exception) raised an exception.
1015
Neil Schemenauer06ded092006-08-04 16:20:30 +00001016- Fix a bug in the ``compiler`` package that caused invalid code to be
1017 generated for nested functions.

1026 raises the correct exceptions.
1027
Thomas Heller1ce433e2006-08-14 16:20:04 +00001028- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1029 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1030
Thomas Heller86720042006-08-14 11:17:48 +00001031- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1032 uses the _as_parameter_ attribute when objects are passed to foreign
1033 function calls. The ctypes version number was changed to 1.0.1.
1034
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001035- Bug #1530559, struct.pack raises TypeError where it used to convert.
1036 Passing float arguments to struct.pack when integers are expected
1037 now triggers a DeprecationWarning.

1075
Tim Peters4643c2f2006-08-10 22:45:34 +00001076- Bug #1069160. Internal correctness changes were made to
1077 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1078 the documentation was changed to state that the return value
1079 is always 1 (normal) or 0 (if the specified thread wasn't found).

1087Core and builtins
1088-----------------
1089
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001090- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001091 returned a long (see PEP 353).
1092
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001093- Bug #1515471: string.replace() accepts character buffers again.
1094
Neal Norwitz07aadb12006-07-30 06:55:48 +00001095- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1096 This provides the proper warning for struct.pack().
1097 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1098
Neal Norwitz0d62a062006-07-30 06:53:31 +00001099- Patch #1531113: Fix augmented assignment with yield expressions.
1100 Also fix a SystemError when trying to assign to yield expressions.
1101
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001102- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1103 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1104 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1105 excessive filesystem operations during imports.
1106
Tim Petersbc24eee2006-07-27 01:14:53 +00001107- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1108 operations on signed longs that are formally undefined by C.
1109 Unfortunately, at least one compiler now cares about that, so complicated
1110 the code to make that compiler happy again.
1111
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001112- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1113
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001114- Patch #1232023: Stop including current directory in search
1115 path on Windows.
1116
Neal Norwitze1fdb322006-07-21 05:32:28 +00001117- Fix some potential crashes found with failmalloc.
1118
Neal Norwitze7563102006-07-17 01:00:16 +00001119- Fix warnings reported by Klocwork's static analysis tool.
1120
Neal Norwitz84be93b2006-07-16 01:50:38 +00001121- Bug #1512814, Fix incorrect lineno's when code within a function
1122 had more than 255 blank lines.
1123
Georg Brandl9dceedb2006-07-12 15:31:17 +00001124- Patch #1521179: Python now accepts the standard options ``--help`` and
1125 ``--version`` as well as ``/?`` on Windows.
1126
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001127- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001128 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001129 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001130
Tim Peters112aad32006-07-19 00:03:19 +00001131- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001132 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001133 new ``sys._current_frames()`` returns a dictionary with one entry,
1134 mapping the faux "thread id" 0 to the current frame.
1135
Ronald Oussoren3075e162006-07-25 20:28:55 +00001136- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001137

Neal Norwitza1f10902006-07-12 07:28:29 +00001139Library
1140-------
1141
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001142- Correction of patch #1455898: In the mbcs decoder, set final=False
1143 for stream decoder, but final=True for the decode function.
1144
Georg Brandl07fec3a2006-08-01 18:49:24 +00001145- os.urandom no longer masks unrelated exceptions like SystemExit or
1146 KeyboardInterrupt.
1147
Tim Peters4643c2f2006-08-10 22:45:34 +00001148- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001149 shutil.copytree on Windows
1150
Georg Brandle34ac7c2006-07-30 11:07:23 +00001151- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1152 refers to file descriptors, not file objects.
1153
Tim Petersc10c9d02006-09-05 02:18:09 +00001154- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001155 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001156 #1513611, and probably others.
1157
Georg Brandledd9b0d2006-07-29 09:33:26 +00001158- Bug #1441397: The compiler module now recognizes module and function
1159 docstrings correctly as it did in Python 2.4.
1160
Tim Peters6f681472006-07-27 23:44:37 +00001161- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1162 lost that tests are sorted by name before being run. This rarely
1163 matters for well-written tests, but can create baffling symptoms if
1164 side effects from one test to the next affect outcomes. ``DocTestFinder``
1165 has been changed to sort the list of tests it returns.
1166
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001167- The distutils version has been changed to 2.5.0, and is now kept

Martin v. Löwis9298eff2006-07-26 12:12:56 +00001170- Bug #978833: Really close underlying socket in _socketobject.close.
1171
Georg Brandl8c036cc2006-08-20 13:15:39 +00001172- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1173 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001174
Georg Brandlcf0c1722006-07-26 07:23:32 +00001175- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1176 to recursive calls and call it with the failing package name.
1177
Martin v. Löwis0b483032006-07-25 09:53:12 +00001178- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1179
Georg Brandlc13c34c2006-07-24 14:09:56 +00001180- Patch #1515343: Fix printing of deprecated string exceptions with a
1181 value in the traceback module.
1182
Greg Ward48fae7a2006-07-23 16:05:51 +00001183- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1184
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001185- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1186
Brett Cannoncaebe222006-07-18 04:41:36 +00001187- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1188 argument tuple. For arguments where zero is illegal, the value is forced to
1189 the minimum value that is correct. This is to support an undocumented but
1190 common way people used to fill in inconsequential information in the time
1191 tuple pre-2.4.
1192
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001193- Patch #1220874: Update the binhex module for Mach-O.
1194
Barry Warsawb110bad2006-07-21 14:51:07 +00001195- The email package has improved RFC 2231 support, specifically for
1196 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1197 (name*0=<blah>) parameter continuations. This may change the types of
1198 values returned from email.message.Message.get_param() and friends.
1199 Specifically in some cases where non-encoded continuations were used,
1200 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1201 will just return the string (since non-encoded continuations don't have
1202 charset and language parts).
1203
1204 Also, whereas % values were decoded in all parameter continuations, they are
1205 now only decoded in encoded parameter parts.
1206
Ronald Oussoren3075e162006-07-25 20:28:55 +00001207- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1208
1209- Bug #1517996: IDLE now longer shows the default Tk menu when a
1210 path browser, class browser or debugger is the frontmost window on MacOS X
1211
Barry Warsaw00decd72006-07-27 23:43:15 +00001212- Patch #1520294: Support for getset and member descriptors in types.py,
1213 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1214 of an object against these built-in types and more importantly, for getting
1215 their docstrings printed in the interactive interpreter's help() function.

1219-----------------
1220
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001221- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1222 a socket operation on a socket with a timeout, the exception will be
1223 caught correctly. Previously, the exception was not caught.
1224
Thomas Heller1393d6a2006-07-28 21:43:20 +00001225- Patch #1529514: The _ctypes extension is now compiled on more
1226 openbsd target platforms.
1227
Tim Peters9cab5932006-07-28 00:30:00 +00001228- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1229 a memory leak, affecting pickles and deep copies.
1230
Tim Petersbc24eee2006-07-27 01:14:53 +00001231- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1235
Thomas Hellerce049a02006-07-14 17:51:14 +00001236- Patch #1521817: Index range checking on ctypes arrays containing
1237 exactly one element enabled again. This allows iterating over these
1238 arrays, without the need to check the array size before.
1239
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001240- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001241 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001242 /dev/null in certain cases; this is now fixed.
1243
Thomas Heller47d7a062006-07-12 08:43:47 +00001244- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1245 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001246
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001247- Because of a misspelled preprocessor symbol, ctypes was always
1248 compiled without thread support; this is now fixed.
1249
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001250- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1251 methods now allow their database parameter to be None as the
1252 sleepycat API allows.
1253
Matt Flemingec926502006-07-28 11:27:27 +00001254- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1255 bluetooth API compared with Linux and FreeBSD.
1256
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001257Tests
1258-----
1259
1260- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1261 how long the test file should take to play. Now accepts taking 2.93 secs
1262 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1263
Georg Brandl4793aa32006-07-28 18:31:39 +00001264- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1265 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1266 run via ``regrtest.py``. Now they do.

1272
Ronald Oussoren26cad082006-08-01 21:00:57 +00001273Mac
1274---
1275
1276- PythonLauncher now works correctly when the path to the script contains
1277 characters that are treated specially by the shell (such as quotes).
1278
1279- Bug #1527397: PythonLauncher now launches scripts with the working directory
1280 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001281 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001282 expect.

1291-----------------
1292
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001293- Bug #1441486: The literal representation of -(sys.maxint - 1)
1294 again evaluates to a int object, not a long.
1295
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001296- Bug #1501934: The scope of global variables that are locally assigned
1297 using augmented assignment is now correctly determined.
1298
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001299- Bug #927248: Recursive method-wrapper objects can now safely
1300 be released.
1301
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001302- Bug #1417699: Reject locale-specific decimal point in float()
1303 and atof().
1304
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001305- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1306 omit a default "error" argument for NULL pointer. This allows
1307 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001308
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001309- Bug #1519018: 'as' is now validated properly in import statements.
1310
Neal Norwitz28746ab2006-07-09 22:14:42 +00001311- On 64 bit systems, int literals that use less than 64 bits are
1312 now ints rather than longs.
1313
Neal Norwitzed657552006-07-10 00:04:44 +00001314- Bug #1512814, Fix incorrect lineno's when code at module scope
1315 started after line 256.
1316
Tim Peters32a83612006-07-10 21:08:24 +00001317- New function ``sys._current_frames()`` returns a dict mapping thread
1318 id to topmost thread stack frame. This is for expert use, and is
1319 especially useful for debugging application deadlocks. The functionality
1320 was previously available in Fazal Majid's ``threadframe`` extension
1321 module, but it wasn't possible to do this in a wholly threadsafe way from
1322 an extension.
1323

1339
Thomas Woutersadd19112006-07-05 11:03:49 +00001340- string.Template() now correctly handles tuple-values. Previously,
1341 multi-value tuples would raise an exception and single-value tuples would
1342 be treated as the value they contain, instead.
1343
Martin v. Löwisede77f52006-07-03 13:01:35 +00001344- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1351 degrees and radians.
1352
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001353- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001354 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001355

1357 is created.
1358
Martin v. Löwis7596e832006-07-01 15:33:37 +00001359- Bug #1513223: .close() of a _socketobj now releases the underlying
1360 socket again, which then gets closed as it becomes unreferenced.
1361
Fred Drake10497c82006-06-29 02:57:48 +00001362- Bug #1504333: Make sgmllib support angle brackets in quoted
1363 attribute values.
1364
1365- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1366 sgmllib ('[' and ']' were not accepted).
1367
Georg Brandl1be63af2006-06-28 20:23:25 +00001368- Fix a bug in the turtle module's end_fill function.
1369
Brett Cannon53ab5b72006-06-22 16:49:14 +00001370- Bug #1510580: The 'warnings' module improperly required that a Warning
1371 category be either a types.ClassType and a subclass of Warning. The proper
1372 check is just that it is a subclass with Warning as the documentation states.
1373
Georg Brandlad29e632006-06-21 17:45:17 +00001374- The compiler module now correctly compiles the new try-except-finally
1375 statement (bug #1509132).
1376
Neal Norwitz60373cd2006-06-22 06:30:50 +00001377- The wsgiref package is now installed properly on Unix.
1378
Vinay Sajip28e57612006-07-01 10:45:20 +00001379- A bug was fixed in logging.config.fileConfig() which caused a crash on
1380 shutdown when fileConfig() was called multiple times.
1381
Gerhard Häring762fbd32006-07-02 17:48:30 +00001382- The sqlite3 module did cut off data from the SQLite database at the first
1383 null character before sending it to a custom converter. This has been fixed
1384 now.
1385
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001386Extension Modules
1387-----------------
1388
Tim Peters112aad32006-07-19 00:03:19 +00001389- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1390 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1391 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001392
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001393- Assigning None to pointer type fields in ctypes structures possible
1394 overwrote the wrong fields, this is fixed now.
1395
1396- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1397 on non-Windows platforms.
1398
1399- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1400 integer or long, without range checking.
1401
1402- Patch #1517790: It is now possible to use custom objects in the ctypes
1403 foreign function argtypes sequence as long as they provide a from_param
1404 method, no longer is it required that the object is a ctypes type.
1405
1406- The '_ctypes' extension module now works when Python is configured
1407 with the --without-threads option.
1408
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001409- Bug #1513646: os.access on Windows now correctly determines write

1424
Tim Peters32a83612006-07-10 21:08:24 +00001425- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001426 Previously, the slight difference could cause compilation errors of the
1427 'zlib' module on systems with more than one version of zlib.
1428
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001429- The MSI compileall step was fixed to also support a TARGETDIR
1430 with spaces in it.

1464 (such as iterating over an integer) have been improved and now include the
1465 type of the offending object to help with debugging.
1466
Brett Cannonea3912b2006-06-13 21:46:41 +00001467- Bug #992017: A classic class that defined a __coerce__() method that returned
1468 its arguments swapped would infinitely recurse and segfault the interpreter.
1469
Neal Norwitz909eb122006-06-12 02:13:21 +00001470- Fix the socket tests so they can be run concurrently.
1471
Neal Norwitzb9845e72006-06-12 02:11:18 +00001472- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001473 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001474
Brett Cannon22565aa2006-06-09 22:31:23 +00001475- Bug #532646: object.__call__() will continue looking for the __call__
1476 attribute on objects until one without one is found. This leads to recursion
1477 when you take a class and set its __call__ attribute to an instance of the
1478 class. Originally fixed for classic classes, but this fix is for new-style.
1479 Removes the infinite_rec_3 crasher.
1480
Georg Brandl24250812006-06-09 18:45:48 +00001481- The string and unicode methods startswith() and endswith() now accept
1482 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1483
Brett Cannonde3b0522006-06-08 17:00:45 +00001484- Buffer objects, at the C level, never used the char buffer
1485 implementation even when the char buffer for the wrapped object was
1486 explicitly requested (originally returned the read or write buffer).
1487 Now a TypeError is raised if the char buffer is not present but is
1488 requested.
1489
Georg Brandlddbaa662006-06-04 21:56:52 +00001490- Patch #1346214: Statements like "if 0: suite" are now again optimized
1491 away like they were in Python 2.4.
1492
Georg Brandlb7c8f542006-05-27 12:30:25 +00001493- Builtin exceptions are now full-blown new-style classes instead of
1494 instances pretending to be classes, which speeds up exception handling
1495 by about 80% in comparison to 2.5a2.
1496
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001497- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1498 Unicode 4.1.
1499
Georg Brandlf4ef1162006-05-26 18:03:31 +00001500- Patch #921466: sys.path_importer_cache is now used to cache valid and
1501 invalid file paths for the built-in import machinery which leads to
1502 fewer open calls on startup.
1503
Tim Peters696cf432006-05-24 21:10:40 +00001504- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1505 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1506 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1507 the number of input digits (it was and remains linear-time for bases
1508 2, 4, 8, 16 and 32).
1509
Tim Petersb713ec22006-05-23 18:45:30 +00001510- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1511 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1512 an integer close to ``sys.maxint``. This was repaired by patch
1513 #1335972, which also gives a nice speedup.
1514
Richard Jonescebbefc2006-05-23 18:28:17 +00001515- Patch #1337051: reduced size of frame objects.
1516
1517- PyErr_NewException now accepts a tuple of base classes as its
1518 "base" parameter.
1519
Richard Jones7c88dcc2006-05-23 10:37:38 +00001520- Patch #876206: function call speedup by retaining allocated frame
1521 objects.
1522
Georg Brandl7b90e162006-05-18 07:01:27 +00001523- Bug #1462152: file() now checks more thoroughly for invalid mode
1524 strings and removes a possible "U" before passing the mode to the
1525 C library function.
1526
Neal Norwitz1004a532006-05-15 07:17:23 +00001527- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1528
Neal Norwitz373f0a72006-05-15 07:04:36 +00001529- Bug #1487966: Fix SystemError with conditional expression in assignment
1530
Martin v. Löwis879768d2006-05-11 13:28:43 +00001531- WindowsError now has two error code attributes: errno, which carries
1532 the error values from errno.h, and winerror, which carries the error
1533 values from winerror.h. Previous versions put the winerror.h values
1534 (from GetLastError()) into the errno attribute.
1535
Martin v. Löwis77736712006-05-04 05:51:03 +00001536- Patch #1475845: Raise IndentationError for unexpected indent.
1537
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001538- Patch #1479181: split open() and file() from being aliases for each other.
1539
Tim Peters44bd9862006-06-01 13:49:23 +00001540- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1541 methods were always silently ignored by dictionaries when comparing keys.
1542 They are now passed through (except when using the C API function
1543 ``PyDict_GetItem()``, whose semantics did not change).
1544
1545- Bug #1456209: In some obscure cases it was possible for a class with a
1546 custom ``__eq__()`` method to confuse dict internals when class instances
1547 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1548 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001550Extension Modules
1551-----------------
1552
Trent Mick960a3f82006-06-28 20:30:41 +00001553- Bug #1295808: expat symbols should be namespaced in pyexpat
1554
1555- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1556
Brett Cannon6ee7d012006-06-08 16:23:04 +00001557- Change binascii.hexlify to accept a read-only buffer instead of only a char
1558 buffer and actually follow its documentation.
1559
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001560- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1561
Nick Coghlanc649ec52006-05-29 12:43:05 +00001562- Patch #1478788 (modified version): The functional extension module has
1563 been renamed to _functools and a functools Python wrapper module added.
1564 This provides a home for additional function related utilities that are
1565 not specifically about functional programming. See PEP 309.
1566
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001567- Patch #1493701: performance enhancements for struct module.
1568
Georg Brandl378d5922006-05-17 14:26:50 +00001569- Patch #1490224: time.altzone is now set correctly on Cygwin.
1570
Georg Brandl8d3342b2006-05-16 07:38:27 +00001571- Patch #1435422: zlib's compress and decompress objects now have a
1572 copy() method.
1573
Andrew MacIntyre92913322006-06-13 15:04:24 +00001574- Patch #1454481: thread stack size is now tunable at runtime for thread
1575 enabled builds on Windows and systems with Posix threads support.
1576
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001577- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1578 (up to the system limit of 32K characters).
1579
1580- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1581 As a result, these functions now raise WindowsError instead of OSError.
1582
Tim Peters7a822da2006-05-25 21:50:17 +00001583- ``time.clock()`` on Win64 should use the high-performance Windows
1584 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1585 Windows platforms).
1586
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001587- Calling Tk_Init twice is refused if the first call failed as that
1588 may deadlock.
1589
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001590- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1591 accept it without potentially using an uninitialized pointer.
1592
1593- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1594 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1595 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001596
Gregory P. Smith372b5832006-06-05 18:48:21 +00001597- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001598 [pybsddb project SF patch number 1466734]
1599
Gregory P. Smith372b5832006-06-05 18:48:21 +00001600- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1601 parameter is supplied. [SF pybsddb bug #1477863]
1602
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001603- bsddb: the __len__ method of a DB object has been fixed to return correct
1604 results. It could previously incorrectly return 0 in some cases.
1605 Fixes SF bug 1493322 (pybsddb bug 1184012).
1606
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001607- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1608 aborts the db transaction safely when a modifier callback fails.
1609 Fixes SF python patch/bug #1408584.
1610
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001611- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001612 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001613 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1614 database calls that would previously deadlock. [SF python bug #775414]
1615
Vinay Sajip28e57612006-07-01 10:45:20 +00001616- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001617
Walter Dörwald4994d952006-06-19 08:07:50 +00001618- Patch #1506645: add Python wrappers for the curses functions
1619 is_term_resized, resize_term and resizeterm.

1623
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001624- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1625 functions.
1626
Martin v. Löwis3798da02006-06-17 18:44:27 +00001627- Patch #812986: Update turtle output even if not tracing.
1628
Vinay Sajip28e57612006-07-01 10:45:20 +00001629- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001630 Tkinter.BaseWidget.
1631
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001632- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1633
Martin v. Löwis337487e2006-06-17 09:15:14 +00001634- Patch #763580: Add name and value arguments to Tkinter variable
1635 classes.
1636
Georg Brandl83cc0d02006-06-14 08:50:03 +00001637- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1638 mime.types file for determining MIME types.
1639
Georg Brandl2605ca82006-06-14 06:08:31 +00001640- Bug #1339007: Shelf objects now don't raise an exception in their
1641 __del__ method when initialization failed.
1642
Martin v. Löwisd8251432006-06-14 05:21:04 +00001643- Patch #1455898: The MBCS codec now supports the incremental mode for
1644 double-byte encodings.
1645
Tim Peters43898b42006-06-14 04:09:25 +00001646- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1647 guarantee that adjacent triples in the return list always describe
1648 non-adjacent blocks. Previously, a pair of matching blocks could end
1649 up being described by multiple adjacent triples that formed a partition
1650 of the matching pair.
1651
Greg Ward0e0c9f42006-06-11 16:24:11 +00001652- Bug #1498146: fix optparse to handle Unicode strings in option help,
1653 description, and epilog.
1654
Greg Wardd1c797e2006-06-11 14:42:41 +00001655- Bug #1366250: minor optparse documentation error.
1656
Greg Ward7f547402006-06-11 00:40:49 +00001657- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1658 clarify docs.
1659
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001660- The wsgiref package has been added to the standard library.
1661
Nick Coghlan676725d2006-06-08 13:54:49 +00001662- The functions update_wrapper() and wraps() have been added to the functools
1663 module. These make it easier to copy relevant metadata from the original
1664 function when writing wrapper functions.
1665
Tim Petersd6a9eef2006-06-05 01:48:21 +00001666- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1667 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001668
Martin v. Löwis3f767792006-06-04 19:36:28 +00001669- Patch #1359618: Speed up charmap encoder by using a trie structure
1670 for lookup.
1671
Tim Petersd609b1a2006-06-02 23:22:51 +00001672- The functions in the ``pprint`` module now sort dictionaries by key
1673 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1674 if and only if its display required more than one line, although that
1675 wasn't documented. The new behavior increases predictability; e.g.,
1676 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1677
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001678- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1679 (thanks for J. J. Lee).
1680
Georg Brandl2b330372006-05-28 20:23:12 +00001681- Patch #1496206: improve urllib2 handling of passwords with respect to
1682 default HTTP and HTTPS ports.
1683
George Yoshidaf3c65de2006-05-28 16:39:09 +00001684- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1685
Bob Ippolito7298f272006-05-23 18:43:47 +00001686- Patch #1281707: speed up gzip.readline.
1687
Georg Brandlb89316f2006-05-17 15:51:16 +00001688- Patch #1180296: Two new functions were added to the locale module:
1689 format_string() to get the effect of "format % items" but locale-aware,
1690 and currency() to format a monetary number with currency sign.
1691
Georg Brandle3a25832006-05-17 14:56:04 +00001692- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1693 and several features added, such as speed and geometry control.
1694
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001695- Patch #1488881: add support for external file objects in bz2 compressed
1696 tarfiles.
1697
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001698- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1699 stdout arguments, making it possible to redirect input and output
1700 for remote debugging.
1701
1702- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1703 a couple of issues, notably handling of long file names using the
1704 GNU LONGNAME extension.
1705
1706- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1707 new flag when ``name`` is already the name of an option flag.
1708
1709- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1710 package.
1711
1712- Patch #1472854: make the rlcompleter.Completer class usable on non-
1713 UNIX platforms.
1714
1715- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1716
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001717- Bug #1472827: correctly escape newlines and tabs in attribute values in
1718 the saxutils.XMLGenerator class.

1754-----------------
1755
Thomas Heller1b046642006-04-18 18:51:06 +00001756- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1757 by converting these apis from macros into exported functions again:
1758
1759 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1760 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1761 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne

1764
Martin v. Löwis45294a92006-04-18 06:24:08 +00001765- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1766
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001767- All uses of PyStructSequence_InitType have been changed to initialize
1768 the type objects only once, even if the interpreter is initialized
1769 multiple times.
1770
Neal Norwitz61546162006-04-14 05:20:28 +00001771- Bug #1454485, array.array('u') could crash the interpreter. This was
1772 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1773 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1774
1775- Py_UNICODE is unsigned. It was always documented as unsigned, but
1776 due to a bug had a signed value in previous versions.
1777
Tim Peters3a5e8b12006-04-11 01:44:07 +00001778- Patch #837242: ``id()`` of any Python object always gives a positive
1779 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1780 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001781 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001782 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001783
Tim Peters3a5e8b12006-04-11 01:44:07 +00001784 def __hash__(self):
1785 return id(self) # WRONG
1786
1787 because a hash result must be a (short) Python int but it was always
1788 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001789 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001790 was always usable as a hash value before this patch. That's no longer
1791 necessarily so.
1792
1793- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001794 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001795 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001796 #1454844)
1797
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001798- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1799 involving generators that have paused outside of any ``try`` or ``with``
1800 blocks. (In 2.5a1, a paused generator that was part of a reference
1801 cycle could not be garbage collected, regardless of whether it was
1802 paused in a ``try`` or ``with`` block.)

1809
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001810- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1811 fails with an error condition.
1812
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001813- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1814
1815- Bug #1117761: bsddb.*open() no longer raises an exception when using
1816 the cachesize parameter.
1817
1818- Bug #1149413: bsddb.*open() no longer raises an exception when using
1819 a temporary db (file=None) with the 'n' flag to truncate on open.
1820
1821- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1822 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001823
Armin Rigoa9017c32006-04-19 11:50:27 +00001824- Patch #1062014: AF_UNIX sockets under Linux have a special
1825 abstract namespace that is now fully supported.
1826

1828-------
1829
Peter Astrand7d1d4362006-07-14 14:04:45 +00001830- Bug #1223937: subprocess.CalledProcessError reports the exit status
1831 of the process using the returncode attribute, instead of
1832 abusing errno.
1833
Tim Peters711bf302006-04-25 03:31:36 +00001834- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1835 a doctest to be skipped (the code is not run, and the expected output
1836 or exception is ignored).
1837
Nick Coghlanda2268f2006-04-24 04:37:15 +00001838- Fixed contextlib.nested to cope with exceptions being raised and
1839 caught inside exit handlers.
1840
Greg Wardab05edc2006-04-23 03:47:58 +00001841- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1842 hex, octal, or binary; add ``append_const`` action; keep going if
1843 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1844 added ``epilog`` for better help generation).
1845
Tim Peters21fbd572006-04-21 21:18:10 +00001846- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1847 called from a thread spawned as a side effect of importing a module.
1848
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001849- The pydoc module now supports documenting packages contained in
1850 .zip or .egg files.
1851
1852- The pkgutil module now has several new utility functions, such
1853 as ``walk_packages()`` to support working with packages that are either
1854 in the filesystem or zip files.
1855
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001856- The mailbox module can now modify and delete messages from
1857 mailboxes, in addition to simply reading them. Thanks to Gregory
1858 K. Johnson for writing the code, and to the 2005 Google Summer of
1859 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001860
Tim Petersc7605f22006-04-17 21:12:33 +00001861- The ``__del__`` method of class ``local`` in module ``_threading_local``
1862 returned before accomplishing any of its intended cleanup.

1869
Anthony Baxtere29002c2006-04-12 12:07:31 +00001870- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1871 Windows. Bug #1469163.
1872
Phillip J. Eby47032112006-04-11 01:07:43 +00001873- The warnings, linecache, inspect, traceback, site, and doctest modules
1874 were updated to work correctly with modules imported from zipfiles or
1875 via other PEP 302 __loader__ objects.
1876
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001877- Patch #1467770: Reduce usage of subprocess._active to processes which

1883
Skip Montanaro262fb922006-04-21 02:31:07 +00001884- The pstats.Stats class accepts an optional stream keyword argument to
1885 direct output to an alternate file-like object.
1886
Anthony Baxter51bcb682006-04-05 14:51:42 +00001887Build
1888-----
1889
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001890- The Makefile now has a reindent target, which runs reindent.py on
1891 the library.
1892
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001893- Patch #1470875: Building Python with MS Free Compiler
1894
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001895- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001896
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001897- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1898 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001899 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001900 CXX from --with-cxx-main, see description in README.
1901
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001902- Patch #1429775: Link extension modules with the shared libpython.
1903
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001904- Fixed a libffi build problem on MIPS systems.
1905
Tim Peters8931ff12006-05-13 23:28:20 +00001906- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1907 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1908 and "%zu" for unsigned integers of type ``size_t``.
1909
Anthony Baxter51bcb682006-04-05 14:51:42 +00001910Tests
1911-----
1912
Nick Coghlanda2268f2006-04-24 04:37:15 +00001913- test_contextlib now checks contextlib.nested can cope with exceptions
1914 being raised and caught inside exit handlers.
1915
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001916- test_cmd_line now checks operation of the -m and -c command switches
1917
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001918- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1919 it separately and by hand. It also wasn't cleaning up its changes to
1920 the current Decimal context.
1921
Thomas Woutersabd08882006-04-26 15:53:30 +00001922- regrtest.py now has a -M option to run tests that test the new limits of
1923 containers, on 64-bit architectures. Running these tests is only sensible
1924 on 64-bit machines with more than two gigabytes of memory. The argument
1925 passed is the maximum amount of memory for the tests to use.

1934-------------
1935
Tim Petersb06d28c2006-05-12 01:57:59 +00001936- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1937
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001938- PEP 343: Added Context Types section to the library reference
1939 and attempted to bring other PEP 343 related documentation into
1940 line with the implementation and/or python-dev discussions.
1941
Tim Peters8dc73d22006-04-24 02:03:16 +00001942- Bug #1337990: clarified that ``doctest`` does not support examples
1943 requiring both expected output and an exception.

Anthony Baxterebed3f62006-04-03 15:03:44 +00001949*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001950
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001951Core and builtins
1952-----------------
1953
Nick Coghlan43832302006-04-23 17:04:07 +00001954- PEP 338: -m command line switch now delegates to runpy.run_module
1955 allowing it to support modules in packages and zipfiles
1956
Martin v. Löwisc661b882006-04-20 04:54:23 +00001957- On Windows, .DLL is not an accepted file name extension for
1958 extension modules anymore; extensions are only found if they
1959 end in .PYD.
1960
Martin v. Löwisea62d252006-04-03 10:56:49 +00001961- Bug #1421664: sys.stderr.encoding is now set to the same value as
1962 sys.stdout.encoding.
1963
Neal Norwitz92e212f2006-04-03 04:48:37 +00001964- __import__ accepts keyword arguments.
1965
Georg Brandlccadf842006-03-31 18:54:53 +00001966- Patch #1460496: round() now accepts keyword arguments.
1967
Anthony Baxter262c00a2006-03-30 10:53:17 +00001968- Fixed bug #1459029 - unicode reprs were double-escaped.
1969
Hye-Shik Changd478f342006-03-23 12:32:36 +00001970- Patch #1396919: The system scope threads are reenabled on FreeBSD
1971 5.4 and later versions.
1972
Neal Norwitze98ccf62006-03-23 05:39:47 +00001973- Bug #1115379: Compiling a Unicode string with an encoding declaration
1974 now gives a SyntaxError.
1975
Georg Brandlabd1ff82006-03-18 07:59:59 +00001976- Previously, Python code had no easy way to access the contents of a
1977 cell object. Now, a ``cell_contents`` attribute has been added
1978 (closes patch #1170323).
1979
Tim Peterscf79aac2006-03-16 01:14:46 +00001980- Patch #1123430: Python's small-object allocator now returns an arena to
1981 the system ``free()`` when all memory within an arena becomes unused
1982 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1983 freed. Some applications will see a drop in virtual memory size now,
1984 especially long-running applications that, from time to time, temporarily
1985 use a large number of small objects. Note that when Python returns an
1986 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001987 platform C library will in turn return that memory to the operating system.
1988 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001989 appears to be effective at least on Microsoft C and gcc-based systems.
1990 Thanks to Evan Jones for hard work and patience.
1991
Georg Brandl533ff6f2006-03-08 18:09:27 +00001992- Patch #1434038: property() now uses the getter's docstring if there is
1993 no "doc" argument given. This makes it possible to legitimately use
1994 property() as a decorator to produce a read-only property.
1995
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001996- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1997 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1998 of requiring an int or long in slicing and a few other contexts, enabling
1999 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2000
Neal Norwitz995acdf2006-03-07 05:01:00 +00002001- Fixed various bugs reported by Coverity's Prevent tool.
2002
Brett Cannonbf364092006-03-01 04:25:17 +00002003- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2004 new exception base class, BaseException, which has a new message attribute.
2005 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2006 Raising a string exception now raises a DeprecationWarning.
2007
Thomas Woutersfb609f42006-02-28 16:37:25 +00002008- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2009 explicitly relative, using 'from .module import name' to mean 'from the same
2010 package as this module is in. Imports without dots still default to the
2011 old relative-then-absolute, unless 'from __future__ import
2012 absolute_import' is used.
2013
Brett Cannona7446e32006-02-27 23:39:10 +00002014- Properly check if 'warnings' raises an exception (usually when a filter set
2015 to "error" is triggered) when raising a warning for raising string
2016 exceptions.
2017
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002018- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002019 The name was removed from Include/code.h.
2020
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002021- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002022
Guido van Rossum1968ad32006-02-25 22:38:04 +00002023- Patch 1433928:
2024 - The copy module now "copies" function objects (as atomic objects).
2025 - dict.__getitem__ now looks for a __missing__ hook before raising
2026 KeyError.
2027
Tim Peters84ef21c2006-02-28 20:39:06 +00002028- PEP 343: with statement implemented. Needs ``from __future__ import
2029 with_statement``. Use of 'with' as a variable will generate a warning.
2030 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002031 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002032 The following objects have __context__ methods:
2033 - The built-in file type.
2034 - The thread.LockType type.
2035 - The following types defined by the threading module:
2036 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2037 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002038
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002039- Fix the encodings package codec search function to only search
2040 inside its own package. Fixes problem reported in patch #1433198.
2041
2042 Note: Codec packages should implement and register their own
2043 codec search function. PEP 100 has the details.
2044
Tim Peters9ea89d22006-06-04 03:26:02 +00002045- PEP 353: Using ``Py_ssize_t`` as the index type.
2046
2047- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2048 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2049 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2050 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2051 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002052
Neal Norwitzfc76d632006-01-10 06:03:13 +00002053- Patch #1400181, fix unicode string formatting to not use the locale.
2054 This is how string objects work. u'%f' could use , instead of .
2055 for the decimal point. Now both strings and unicode always use periods.
2056
Neal Norwitz671b9e32006-01-09 07:07:12 +00002057- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2058 configure would break checking curses.h.
2059
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002060- Bug #959576: The pwd module is now builtin. This allows Python to be
2061 built on UNIX platforms without $HOME set.
2062
Neal Norwitzc10978f2005-12-19 06:07:16 +00002063- Bug #1072182, fix some potential problems if characters are signed.
2064
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002065- Bug #889500, fix line number on SyntaxWarning for global declarations.
2066
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002067- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2068
Neal Norwitze7214a12005-12-18 05:03:17 +00002069- Support for converting hex strings to floats no longer works.
2070 This was not portable. float('0x3') now raises a ValueError.
2071
Barry Warsaw2a38a862005-12-18 01:27:35 +00002072- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002073 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002074 is now displayed in interactive prompt banner.
2075
Georg Brandlfa166682005-12-17 21:45:17 +00002076- Implementation of PEP 341 - Unification of try/except and try/finally.
2077 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002078 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002079
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002080- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2081 now encodes backslash correctly.
2082
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002083- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2084
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002085- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002086 and long longs.
2087
Neal Norwitz67715f02005-11-09 06:59:35 +00002088- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002089 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002090 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002091
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002092- Replaced most Unicode charmap codecs with new ones using the
2093 new Unicode translate string feature in the builtin charmap
2094 codec; the codecs were created from the mapping tables available
2095 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2096 encodings now include a mapping for the Apple logo)
2097
Tim Peterse3547fd2005-12-16 23:13:57 +00002098- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002099
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002100- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002101
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002102- A new AST parser implementation was completed. The abstract
2103 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002104 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002105
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002106- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002107 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2108
Neal Norwitz708e51a2005-10-03 04:48:15 +00002109- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2110
Neal Norwitz11bd1192005-10-03 00:54:56 +00002111- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2112 Provide a warning when a directory is passed on the command line.
2113
Neal Norwitz40d37812005-10-02 01:48:49 +00002114- Fix segfault with invalid coding.
2115
2116- SF bug #772896: unknown encoding results in MemoryError.
2117
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002118- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002119 supported a __len__() method which evaluated to False when the iterator
2120 was empty.
2121
Guido van Rossum630db602005-09-20 18:49:54 +00002122- On 64-bit platforms, when __len__() returns a value that cannot be
2123 represented as a C int, raise OverflowError.
2124
Skip Montanarof8948ca2005-09-19 03:54:46 +00002125- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002126 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002127
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002128- SF bug #893549: parsing keyword arguments was broken with a few format
2129 codes.
2130
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002131- Changes donated by Elemental Security to make it work on AIX 5.3
2132 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2133 bug #105470: test_pwd fails on 64bit system (Opteron).
2134
Guido van Rossum539c6622005-09-14 17:49:54 +00002135- Changes donated by Elemental Security to make it work on HP-UX 11 on
2136 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2137
Georg Brandl4550b8d2005-08-26 06:43:52 +00002138- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002139 (fixes bug #1119418).
2140
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002141- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2142
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002143- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2144 exceptions that cause a function to exit.
2145
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002146- The implementation of set() and frozenset() was revised to use its
2147 own internal data structure. Memory consumption is reduced by 1/3
2148 and there are modest speed-ups as well. The API is unchanged.
2149
Tim Petersde7990b2005-07-17 23:45:23 +00002150- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2151
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002152- SF bug #1229429: PyObject_CallMethod failed to decrement some
2153 reference counts in some error exit cases.
2154
Tim Petersecc6e6a2005-07-10 22:30:55 +00002155- SF bug #1185883: Python's small-object memory allocator took over
2156 a block managed by the platform C library whenever a realloc specified
2157 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002158 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002159 portable way to copy data from the C-managed block into Python's
2160 small-object space without risking a memory fault. Python's small-object
2161 realloc now leaves such blocks under the control of the platform C
2162 realloc.
2163
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002164- SF bug #1232517: An overflow error was not detected properly when
2165 attempting to convert a large float to an int in os.utime().
2166
Raymond Hettinger3296e692005-06-29 23:29:56 +00002167- SF bug #1224347: hex longs now print with lowercase letters just
2168 like their int counterparts.
2169
Michael W. Hudson188d4362005-06-20 16:52:57 +00002170- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2171 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2172 interpreter states; back out that fix and do a better job (see
2173 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2174 for a longer write-up of the problem).
2175
Michael W. Hudsondf888462005-06-03 14:41:55 +00002176- SF patch #1180995: marshal now uses a binary format by default when
2177 serializing floats.
2178
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002179- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2180 the routines that promise to produce IEEE 754 binary representations
2181 of floats now simply copy bytes around.
2182
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002183- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2184 278.
2185
Brett Cannonc3647ac2005-04-26 03:45:26 +00002186- patch #1109424: int, long, float, complex, and unicode now check for the
2187 proper magic slot for type conversions when subclassed. Previously the
2188 magic slot was ignored during conversion. Semantics now match the way
2189 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002190 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002191 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002192 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002193
Barry Warsawc8d907c2005-04-19 23:43:40 +00002194- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2195 NULL, now raise an AttributeError when attempting to set or delete the
2196 attribute. Previously a TypeError was raised, but this was inconsistent
2197 with the equivalent pure-Python implementation.
2198
Michael W. Hudson774479c2005-04-18 08:46:17 +00002199- It is now safe to call PyGILState_Release() before
2200 PyEval_InitThreads() (note that if there is reason to believe there
2201 are multiple threads around you still must call PyEval_InitThreads()
2202 before using the Python API; this fix is for extension modules that
2203 have no way of knowing if Python is multi-threaded yet).
2204
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002205- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2206 disabled caused a crash.
2207
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002208- Bug #1165306: instancemethod_new allowed the creation of a method
2209 with im_class == im_self == NULL, which caused a crash when called.
2210
Tim Petersecc6e6a2005-07-10 22:30:55 +00002211- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002212 fixes the crash seen in bug #1165761
2213
Raymond Hettinger96229b12005-03-11 06:49:40 +00002214- Added two new builtins, any() and all().
2215
Brett Cannon409d8f22005-03-05 06:47:57 +00002216- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002217 (e.g., ``class C(): pass`` is no longer a syntax error).
2218 Patch #1176012 added support to the 'parser' module and 'compiler' package
2219 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002220
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002221- Patch #1115086: Support PY_LONGLONG in structmember.
2222
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002223- Bug #1155938: new style classes did not check that __init__() was
2224 returning None.
2225
Tim Petersecc6e6a2005-07-10 22:30:55 +00002226- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002227 ('\') with a specific error message.
2228
Martin v. Löwisff232d72005-03-03 09:24:38 +00002229- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2230
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002231- Bug #1124295: the __name__ attribute of file objects was
2232 inadvertently made inaccessible in restricted mode.
2233
Tim Petersecc6e6a2005-07-10 22:30:55 +00002234- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002235 an ferror() call.
2236
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002237- min() and max() now support key= arguments with the same meaning as in
2238 list.sort().
2239
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002240- The peephole optimizer now performs simple constant folding in expressions:
2241 (2+3) --> (5).
2242
Raymond Hettingera422c342005-01-11 03:03:27 +00002243- set and frozenset objects can now be marshalled. SF #1098985.
2244
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002245- Bug #1077106: Poor argument checking could cause memory corruption
2246 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002247
Jeremy Hyltonab630502005-02-04 18:44:06 +00002248- The parser did not complain about future statements in illegal
2249 positions. It once again reports a syntax error if a future
2250 statement occurs after anything other than a doc string.
2251
Neil Schemenauercf52c072005-08-12 17:34:58 +00002252- Change the %s format specifier for str objects so that it returns a
2253 unicode instance if the argument is not an instance of basestring and
2254 calling __str__ on the argument returns a unicode instance.
2255
Tim Petersf4e69282006-02-27 17:15:31 +00002256- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2257 current thread state when the auto-GIL-state machinery knows about
2258 it (since the thread state is being deleted, continuing to remember it
2259 can't help, but can hurt if another thread happens to get created with
2260 the same thread id).
2261
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002262Extension Modules
2263-----------------
2264
Georg Brandl43f08a82006-03-31 18:01:16 +00002265- Patch #1380952: fix SSL objects timing out on consecutive read()s

2268
Anthony Baxterfa869072006-03-20 05:21:58 +00002269- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
2270 In addition, the existing ulaw code was updated.
2271
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002272- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00002273 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002274
Neal Norwitz10be10c2006-03-16 06:50:13 +00002275- Everything under lib-old was removed. This includes the following modules:
2276 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00002277 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00002278 util, whatsound, whrandom, zmod
2279
2280- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2281
2282- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002283 is deprecated. The undocumented re.engine variable no longer exists.
2284
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002285- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2286 SS2 (single-shift 2) escape sequences correctly.
2287
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002288- The unicodedata module was updated to the 4.1 version of the Unicode
2289 database. The 3.2 version is still available as unicodedata.db_3_2_0
2290 for applications that require this specific version (such as IDNA).
2291
Neal Norwitzb62c4332006-03-04 18:35:47 +00002292- The timing module is no longer built by default. It was deprecated
2293 in PEP 4 in Python 2.0 or earlier.
2294
Guido van Rossum1968ad32006-02-25 22:38:04 +00002295- Patch 1433928: Added a new type, defaultdict, to the collections module.
2296 This uses the new __missing__ hook behavior added to dict (see above).
2297
Georg Brandldbd83392006-02-20 09:42:33 +00002298- Bug #854823: socketmodule now builds on Sun platforms even when
2299 INET_ADDRSTRLEN is not defined.
2300
Georg Brandlf4f44152006-02-18 22:29:33 +00002301- Patch #1393157: os.startfile() now has an optional argument to specify
2302 a "command verb" to invoke on the file.
2303
Neal Norwitz082b2df2006-02-07 07:04:46 +00002304- Bug #876637, prevent stack corruption when socket descriptor
2305 is larger than FD_SETSIZE.
2306
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00002307- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
2308 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
2309 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
2310
Martin v. Löwis57a34e82006-02-04 19:12:37 +00002311- Patch #1422385: The nis module now supports access to domains other
2312 than the system default domain.
2313
Martin v. Löwis14694662006-02-03 12:54:16 +00002314- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2315 are reported, the limit on path name lengths is removed, and stat reports
2316 WindowsError now (instead of OSError).
2317
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002318- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.
2319

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002452- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2453 been renamed to have only a single underscore prefix. This was done to
2454 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002455
Nick Coghlan43832302006-04-23 17:04:07 +00002456- PEP 338: new module runpy defines a run_module function to support
2457 executing modules which provide access to source code or a code object
2458 via the PEP 302 import mechanisms.
2459
Anthony Baxter93f5b932006-04-03 08:05:07 +00002460- The email module's parsedate_tz function now sets the daylight savings

2468 in attribute values.
2469
Anthony Baxterc51ee692006-04-01 00:57:31 +00002470- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002471 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002472 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002473 module will not be built.
2474
Tim Petersc17976e2006-04-01 00:26:53 +00002475- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2476 aren't officially supported here, and trying to use them will probably
2477 raise an exception some day. But dicts have been allowed, and "mostly
2478 worked", so support for them won't go away without warning.
2479
Georg Brandl338ef7d2006-03-31 18:42:16 +00002480- Bug #1445068: getpass.getpass() can now be given an explicit stream

2498
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002499- email 4.0 package now integrated. This is largely the same as the email 3.0
2500 package that was included in Python 2.3, except that PEP 8 module names are
2501 now used (e.g. mail.message instead of email.Message). The MIME classes
2502 have been moved to a subpackage (e.g. email.mime.text instead of
2503 email.MIMEText). The old names are still supported for now. Several
2504 deprecated Message methods have been removed and lots of bugs have been
2505 fixed. More details can be found in the email package documentation.
2506
Walter Dörwald40108c92006-03-27 08:15:44 +00002507- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2508 (a subclass of tuple) that provides incremental decoders and encoders
2509 (a way to use stateful codecs without the stream API). Python functions
2510 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2511 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2512 have been added.

2515 a ValueError instead of a StopIteration now (like file and cString.String do).
2516 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2517 called before (like file and StringIO.StringIO do).

Neal Norwitzab86f8e2005-12-23 21:44:36 +00002584- Patch #1157027: cookielib mishandles RFC 2109 cookies in Netscape mode
2585
Neal Norwitz338e7862005-12-23 21:27:46 +00002586- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
2587 LoadError as documented, instead of IOError. For compatibility,
2588 LoadError subclasses IOError.
2589
Brett Cannon3cbd0382005-12-16 22:49:23 +00002590- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00002591 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2592 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2593 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2594 Ronald L. Rivest offered this advice for Python:
2595
2596 "The consensus of researchers in this area (at least as
2597 expressed at the NIST Hash Function Workshop 10/31/05),
2598 is that SHA-256 is a good choice for the time being, but
2599 that research should continue, and other alternatives may
2600 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002601
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002602- Added a subset of Fredrik Lundh's ElementTree package. Available

2644
Georg Brandl532efab2005-08-24 22:34:21 +00002645- Patch #848017: Make Cookie more RFC-compliant. Use CRLF as default output
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002646 separator and do not output trailing semicolon.
Georg Brandl532efab2005-08-24 22:34:21 +00002647
Georg Brandlb9256022005-08-24 18:46:39 +00002648- Patch #1062060: urllib.urlretrieve() now raises a new exception, named
2649 ContentTooShortException, when the actually downloaded size does not
2650 match the Content-Length header.
2651

2655 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002656 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002657

2671
Georg Brandla4a8b822005-07-15 09:13:21 +00002672- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
2673 parameter, but uses the usual "kwargs=None".
2674
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002675- textwrap now processes text chunks at O(n) speed instead of O(n**2).

2677
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00002678- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
2679 to W3C name (404 -> 'Not Found'). RFE #1216944.
2680
Georg Brandl9e43acf2005-07-04 17:16:07 +00002681- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2682 as this can cause problems with apps closing all file descriptors.

2695 Bug #1224621.
2696
Raymond Hettinger68c04532005-06-10 11:05:19 +00002697- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002698 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002699 the generate_tokens() function now accepts a callable argument that
2700 terminates by raising StopIteration.
2701
Georg Brandl9166e1a2005-06-04 09:20:03 +00002702- Bug #1196315: fix weakref.WeakValueDictionary constructor.

2706
Skip Montanaro174dd222005-05-14 20:54:16 +00002707- Patch #1120353: The xmlrpclib module provides better, more transparent,
2708 support for datetime.{datetime,date,time} objects. With use_datetime set
2709 to True, applications shouldn't have to fiddle with the DateTime wrapper
2710 class at all.
2711
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002712- distutils.commands.upload was added to support uploading distribution

2714
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002715- distutils.commands.register now encodes the data as UTF-8 before posting
2716 them to PyPI.
2717
Raymond Hettinger267b8682005-03-27 10:47:39 +00002718- decimal operator and comparison methods now return NotImplemented
2719 instead of raising a TypeError when interacting with other types. This
2720 allows other classes to implement __radd__ style methods and have them
2721 work as expected.
2722
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002723- Bug #1163325: Decimal infinities failed to hash. Attempting to
2724 hash a NaN raised an InvalidOperation instead of a TypeError.
2725
Tim Petersecc6e6a2005-07-10 22:30:55 +00002726- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002727 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2728

Martin v. Löwisa4dac402005-03-03 11:39:45 +00002738 profile.py if available.
2739
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00002740- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
2741

2760
Guido van Rossumd0641422005-02-03 15:01:24 +00002761- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2762 disables recursive traversal through instance attributes, which can
2763 be exploited in various ways.
2764
Tim Peterse3547fd2005-12-16 23:13:57 +00002765- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002766 flags on the HTTP listening socket.
2767
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002768- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2769 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2770
Fred Drakefbdeaad2006-07-29 16:56:15 +00002771- Patches #893642, #1039083: add allow_none, encoding arguments to
2772 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002773
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002774- Bug #1110478: Revert os.environ.update to do putenv again.

Thomas Hellerd6c6e222005-01-20 19:20:16 +00002776- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2777
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002778- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2779
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002780- Enhancements to the csv module:
2781
2782 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002783 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002784 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002785 + Dialect parameter parsing has been re-implemented to improve error
2786 reporting.
2787 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2788 dictates.
2789 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002790 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002791 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002792 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2793 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002794 + reader now allows \r characters to be quoted (previously it only allowed
2795 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002796 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002797 + Dialect classes passed to the module are no longer instantiated by
2798 the module before being parsed (the former validation scheme required
2799 this, but the mechanism was unreliable).
2800 + The dialect registry now contains instances of the internal
2801 C-coded dialect type, rather than references to python objects.
2802 + the internal c-coded dialect type is now immutable.
2803 + register_dialect now accepts the same keyword dialect specifications
2804 as the reader and writer, allowing the user to register dialects
2805 without first creating a dialect class.
2806 + a configurable limit to the size of parsed fields has been added -
2807 previously, an unmatched quote character could result in the entire
2808 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002809 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002810 the parser field size limit (returning the former limit). The initial
2811 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002812 + A line_num attribute has been added to the reader object, which tracks
2813 the number of lines read from the source iterator. This is not
2814 the same as the number of records returned, as records can span
2815 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002816 + reader and writer objects were not being registered with the cyclic-GC.
2817 This has been fixed.
2818
Brett Cannone6539c42005-01-08 02:43:53 +00002819- _DummyThread objects in the threading module now delete self.__block that is
2820 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2821 lock primitives tend to be limited in number and thus should not be wasted on
2822 a _DummyThread object. Fixes bug #1089632.
2823
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002824- The imghdr module now detects Exif files.
2825
Raymond Hettinger6065d322004-12-20 23:51:53 +00002826- StringIO.truncate() now correctly adjusts the size attribute.
2827 (Bug #951915).
2828
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002829- locale.py now uses an updated locale alias table (built using
2830 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2831 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002832 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002833
Raymond Hettinger3557f422004-12-07 12:02:02 +00002834- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2835
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002836- the pickle module no longer accepts the deprecated None option in the
2837 args tuple returned by __reduce__().
2838
Brett Cannon84667c02004-12-07 03:25:18 +00002839- optparse now optionally imports gettext. This allows its use in setup.py.
2840
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002841- the pickle module no longer uses the deprecated bin parameter.
2842
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002843- the shelve module no longer uses the deprecated binary parameter.
2844
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002845- the pstats module no longer uses the deprecated ignore() method.
2846
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002847- the filecmp module no longer uses the deprecated use_statcache argument.
2848
Raymond Hettinger664347b2004-12-04 21:21:53 +00002849- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2850 extended or overridden by subclasses. Formerly, the subclassed method would
2851 be ignored by the rest of the module. (Bug #1078905).
2852
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002853- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002854 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002855
Walter Dörwald36733692004-12-22 12:50:50 +00002856- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2857 once when a size argument is given. This prevents a buffer overflow in the
2858 tokenizer with very long source lines.
2859
Barry Warsaw538561e2006-01-01 21:48:54 +00002860- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2861 immediately after creating the object, without any intervening
2862 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002863
Skip Montanaro05885812005-01-16 20:48:27 +00002864- The reconvert.quote function can now emit triple-quoted strings. The
2865 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002866
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002867- ``UserString.MutableString`` now supports negative indices in
2868 ``__setitem__`` and ``__delitem__``
2869
Greg Ward40407942005-03-05 02:53:17 +00002870- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2871 correctly.
2872
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002873- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2874 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2875 character even if the user has passed a size parameter to get a proper
2876 line ending. Remove the special handling of a "\r\n" that has been split
2877 between two lines.
2878
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002879- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2880 about illegal code points. The codec now supports PEP 293 style error
2881 handlers.
2882
Walter Dörwald78a78b02005-09-01 12:04:29 +00002883- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002884 from the input stream, so that the output is a byte string in the correct
2885 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002886
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002887- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2888 considering it exactly like a '*'.
2889
Walter Dörwald007f8df2005-10-09 19:42:27 +00002890- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2891 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002892
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002893- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2894
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002895- Patch #1413711: Certain patterns of differences were making difflib
2896 touch the recursion limit.
2897
Walter Dörwald58917a62006-03-31 15:26:22 +00002898- Bug #947906: An object oriented interface has been added to the calendar
2899 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002900 called as a script (e.g. via ``python -mcalendar``). Localized month and
2901 weekday names can be ouput (even if an exotic encoding is used) using
2902 special classes that use unicode.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002904Build
2905-----
2906
Neal Norwitz602d3392006-03-31 08:21:40 +00002907- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2908 by using -mieee gcc option.
2909

2911
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002912- Build support for Win64-AMD64 was added.
2913
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002914- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2915
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002916- Patch #881820: look for openpty and forkpty also in libbsd.
2917
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002918- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2919 The zlib module is now builtin on Windows.
2920
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002921- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2922
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002923- Bug #1189330: configure did not correctly determine the necessary
2924 value of LINKCC if python was built with GCC 4.0.
2925
Trent Mick8321b422005-07-26 02:29:21 +00002926- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2927 vulnerability in zlib 1.2.1 and 1.2.2.
2928
Brett Cannon08cd5982005-04-24 22:26:38 +00002929- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2930 flags that change binary compatibility. Changes were also made to
2931 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002932 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002933
Bob Ippolitoed233462005-03-29 13:47:59 +00002934- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2935 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2936 no longer exists). This configure patch makes things right.
2937
Martin v. Löwise2713be2005-03-08 15:03:08 +00002938- Bug #1158607: Build with --disable-unicode again.
2939
Brett Cannon46d96232005-02-16 00:07:19 +00002940- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2941 defined. Discovered as a result of not being able to build on OS X.
2942
Brett Cannon516592f2004-12-07 00:42:59 +00002943- setup.py now uses the directories specified in LDFLAGS using the -L option
2944 and in CPPFLAGS using the -I option for adding library and include
2945 directories, respectively, for compiling extension modules against. This has
2946 led to the core being compiled using the values in CPPFLAGS. It also removes
2947 the need for the special-casing of both DarwinPorts and Fink for darwin since
2948 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2949 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2950 Fink, ``-I/opt/local/include`` for DarwinPorts).
2951
Brett Cannon43802422005-02-10 20:48:03 +00002952- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2953 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2954 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2955 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002957C API
2958-----
2959
Tim Petersc9d78aa2006-03-26 23:27:58 +00002960- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2961 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2962 is obtained via the ``PyObject_`` family, it must be released via the
2963 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2964 always been officially true, but when Python's small-object allocator was
2965 introduced, an attempt was made to cater to a few extension modules
2966 discovered at the time that obtained memory via ``PyObject_New`` but
2967 released it via ``PyMem_DEL``. It's years later, and if such code still
2968 exists it will fail now (probably with segfaults, but calling wrong
2969 low-level memory management functions can yield many symptoms).
2970
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002971- Added a C API for set and frozenset objects.
2972
Raymond Hettinger66517482004-12-03 11:45:13 +00002973- Removed PyRange_New().
2974
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002975- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2976 mapping argument now. This string is used as a mapping table. Byte values
2977 greater than the length of the string and 0xFFFE are treated as undefined
2978 mappings.

2983
Martin v. Löwis4d394df2005-01-23 09:19:22 +00002984- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002985
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002986- Patch #1276356: New resource "urlfetch" is implemented. This enables
2987 even impatient people to run tests that require remote files.
