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 Norwitz8b2bfbc2007-05-23 06:35:32 +000015- Add -3 option to the interpreter to warn about features that are
16 deprecated and will be changed/removed in Python 3.0.
17
Georg Brandl2134e752007-05-21 20:34:16 +000018- Patch #1686487: you can now pass any mapping after '**' in function
19 calls.
20
Collin Winter62903052007-05-18 23:11:24 +000021- except clauses may now be spelled either "except E, target:" or
22 "except E as target:". This is to provide forwards compatibility with
23 Python 3.0.
24
Brett Cannon229cee22007-05-05 01:34:02 +000025- Deprecate BaseException.message as per PEP 352.
26
Armin Rigo9790a272007-05-02 19:23:31 +000027- Bug #1303614: don't expose object's __dict__ when the dict is
28 inherited from a builtin base.
29
Vinay Sajip8549ce32007-05-06 17:53:37 +000030- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +000031 setting a plain string, ie don't expand to single letter identifiers.
32
Raymond Hettinger13936692007-04-11 18:40:58 +000033- Request #1191699: Slices can now be pickled.
34
Raymond Hettinger4db5fe92007-04-12 04:10:00 +000035- Request #1193128: str.translate() now allows a None argument for
36 translations that only remove characters without re-mapping the
37 remaining characters.
38
Georg Brandl5cb76c12007-03-21 09:00:39 +000039- Patch #1682205: a TypeError while unpacking an iterable is no longer
40 masked by a generic one with the message "unpack non-sequence".
41
Neal Norwitzaa754b72007-03-21 06:39:48 +000042- Remove unused file Python/fmod.c.
43
Guido van Rossum143b5642007-03-23 04:58:42 +000044- Bug #1683368: The object.__init__() and object.__new__() methods are
45 now stricter in rejecting excess arguments. The only time when
46 either allows excess arguments is when it is not overridden and the
47 other one is. For backwards compatibility, when both are
48 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +000049 warning later). Also, type.__init__() insists on the same signature
50 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +000051
Georg Brandl2b869942007-03-17 16:08:45 +000052- Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
53 to complex using its __complex__() method before falling back to the
54 __float__() method. Therefore, the functions in the cmath module now
55 can operate on objects that define a __complex__() method.
56
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +000057- Patch #1623563: allow __class__ assignment for classes with __slots__.
58 The old and the new class are still required to have the same slot names.
59
Collin Winter77c67bd2007-03-16 04:11:30 +000060- Patch #1642547: Fix an error/crash when encountering syntax errors in
61 complex if statements.
62
Žiga Seilnacht20f43d32007-03-15 11:44:55 +000063- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
64 is called with an object that is faking its type.
65
Žiga Seilnacht71436f02007-03-14 12:24:09 +000066- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
67 name.
68
Georg Brandl5240d742007-03-13 20:46:32 +000069- Patch #1444529: the builtin compile() now accepts keyword arguments.
70
Georg Brandl7b9c5552007-03-12 14:30:05 +000071- Bug #1678647: write a newline after printing an exception in any
72 case, even when converting the value to a string failed.
73
Georg Brandl871f1bc2007-03-12 13:17:36 +000074- The dir() function has been extended to call the __dir__() method on
75 its argument, if it exists. If not, it will work like before. This allows
76 customizing the output of dir() in the presence of a __getattr__().
77
Collin Winter276887b2007-03-12 16:11:39 +000078- Patch #922167: Python no longer segfaults when faced with infinitely
79 self-recursive reload() calls (as reported by bug #742342).
80
Žiga Seilnacht89032082007-03-11 15:54:54 +000081- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
82
Collin Wintere38051d2007-03-09 20:33:07 +000083- Patch #1491866: change the complex() constructor to allow parthensized
84 forms. This means complex(repr(x)) now works instead of raising a
85 ValueError.
86
Georg Brandlaa2321b2007-03-07 00:40:28 +000087- Patch #703779: unset __file__ in __main__ after running a file. This
88 makes the filenames the warning module prints much more sensible when
89 a PYTHONSTARTUP file is used.
90
Georg Brandl49aafc92007-03-07 00:34:46 +000091- Variant of patch #697613: don't exit the interpreter on a SystemExit
92 exception if the -i command line option or PYTHONINSPECT environment
93 variable is given, but break into the interactive interpreter just like
94 on other exceptions or normal program exit.
95
Georg Brandl00cd8182007-03-06 18:41:12 +000096- Patch #1638879: don't accept strings with embedded NUL bytes in long().
97
Georg Brandl098cd692007-03-06 12:17:50 +000098- Bug #1674503: close the file opened by execfile() in an error condition.
99
Georg Brandl0fca97a2007-03-05 22:28:08 +0000100- Patch #1674228: when assigning a slice (old-style), check for the
101 sq_ass_slice instead of the sq_slice slot.
102
Neal Norwitz88516a62007-02-26 22:41:45 +0000103- When printing an unraisable error, don't print exceptions. before the name.
104 This duplicates the behavior whening normally printing exceptions.
105
Martin v. Löwisfd963262007-02-09 12:19:32 +0000106- Bug #1653736: Properly discard third argument to slot_nb_inplace_power.
107
Brett Cannon129bd522007-01-30 21:34:36 +0000108- PEP 352: Raising a string exception now triggers a TypeError. Attempting to
109 catch a string exception raises DeprecationWarning.
110
Brett Cannonf5bee302007-01-23 23:21:22 +0000111- Bug #1377858: Fix the segfaulting of the interpreter when an object created
112 a weakref on itself during a __del__ call for new-style classes (classic
113 classes still have the bug).
114
Martin v. Löwis6c5c5022007-01-23 21:11:47 +0000115- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
116 frame's thread state.
117
Thomas Wouters6ed19652007-01-23 13:50:49 +0000118- patch #1630975: Fix crash when replacing sys.stdout in sitecustomize.py
119

121
Neal Norwitz72cd02c2007-01-05 05:25:22 +0000122- Prevent seg fault on shutdown which could occur if an object
123 raised a warning.
124
Martin v. Löwis7b7c9d42007-01-04 21:06:12 +0000125- Bug #1566280: Explicitly invoke threading._shutdown from Py_Main,
126 to avoid relying on atexit.
127
Raymond Hettinger94547f72006-12-20 06:42:06 +0000128- Bug #1590891: random.randrange don't return correct value for big number

140 the tuple isn't used as the "exception arguments tuple".
141

143
Thomas Hellerdf08f0b2006-10-27 18:31:36 +0000144- Bug #1576174: WindowsError now displays the windows error code
145 again, no longer the posix error code.
146
Martin v. Löwisb5bc5372006-10-27 06:16:31 +0000147- Patch #1549049: Support long values in structmember, issue warnings
148 if the assigned value for structmember fields gets truncated.
149
Neal Norwitzcbeb6872006-10-14 21:33:38 +0000150- Update the peephole optimizer to remove more dead code (jumps after returns)
151 and inline unconditional jumps to returns.
152
Georg Brandl2c1375c2006-10-12 11:27:59 +0000153- Bug #1545497: when given an explicit base, int() did ignore NULs
154 embedded in the string to convert.
155
Georg Brandl846f73a2006-10-08 07:11:54 +0000156- Bug #1569998: break inside a try statement (outside a loop) is now
157 recognized and rejected.
158
Armin Rigo7ccbca92006-10-04 12:17:45 +0000159- list.pop(x) accepts any object x following the __index__ protocol.
160
161- Fix some leftovers from the conversion from int to Py_ssize_t
162 (relevant to strings and sequences of more than 2**31 items).
163
164- A number of places, including integer negation and absolute value,
165 were fixed to not rely on undefined behaviour of the C compiler
166 anymore.
Martin v. Löwis820d6ac2006-10-04 05:47:34 +0000167

173 use them).
174
Georg Brandla10d3af2006-09-24 12:35:36 +0000175- Fix a bug in the parser's future statement handling that led to "with"

184
Brett Cannon9adeab72006-09-20 18:34:28 +0000185- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
186 allows calling unicode() on exceptions classes directly to succeed.
187
Georg Brandlec6c2df2006-09-11 09:38:35 +0000188- Make _PyGILState_NoteThreadState() static, it was not used anywhere

196 imports (if not in package and if beyond toplevel package).
197
Tim Petersc10c9d02006-09-05 02:18:09 +0000198- Overflow checking code in integer division ran afoul of new gcc

206 head is the original string if sep was not found.
207
Neal Norwitzdac090d2006-09-05 03:53:08 +0000208- Bug #1520864: unpacking singleton tuples in list comprehensions and
209 generator expressions (x for x, in ... ) works again. Fixing this problem

236
Neal Norwitz42dd86b2007-05-11 06:57:33 +0000237- The popen2 module and os.popen* are deprecated. Use the subprocess module.

251 (as opposed to the command line) will now write file names ending in
252 ".cpp" too.
253
Facundo Batistad918a652007-04-24 13:54:38 +0000254- As specified in RFC 2616, an HTTP response like 2xx indicates that

Facundo Batista70f996b2007-05-21 17:32:32 +0000270 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +0000271

Georg Brandl8f06d022007-03-16 07:55:09 +0000283- Bug #1681228: the webbrowser module now correctly uses the default
284 GNOME or KDE browser, depending on whether there is a session of one
285 of those present. Also, it tries the Windows default browser before
286 trying Mozilla variants.

375 and TestSuite subclasses (not instances) are no longer accepted in
376 TestSuite.addTest(). This should cause no incompatibility since it

Neal Norwitz8a267062006-08-19 04:25:29 +0000882- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx macro
883 so it can be used as an expression.

895
Brett Cannon5e263512007-05-20 23:17:38 +0000896- Removed the macfs module. It had been deprecated since Python 2.5. This
897 lead to the deprecation of macostools.touched() as it relied solely on macfs
898 and was a no-op under OS X.

906Core and builtins
907-----------------
908
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000909- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000910 compared equal or unequal to a string and a UnicodeDecodeError
911 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000912
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000913 Instead, the equal (==) and unequal (!=) comparison operators will
914 now issue a UnicodeWarning and interpret the two objects as
915 unequal. The UnicodeWarning can be filtered as desired using
916 the warning framework, e.g. silenced completely, turned into an
917 exception, logged, etc.
918
919 Note that compare operators other than equal and unequal will still
920 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000921
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000922- Fix segfault when doing string formatting on subclasses of long.
923
924- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
925 with new-style classes.
926
927- Fix bug related to __len__ functions returning negative values with
928 classic classes.
929
930- Patch #1538606, Fix __index__() clipping. There were some problems
931 discovered with the API and how integers that didn't fit into Py_ssize_t
932 were handled. This patch attempts to provide enough alternatives
933 to effectively use __index__.
934
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000935- Bug #1536021: __hash__ may now return long int; the final hash
936 value is obtained by invoking hash on the long int.
937
Thomas Hellerab1049c2006-08-08 17:37:00 +0000938- Bug #1536786: buffer comparison could emit a RuntimeWarning.
939
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000940- Bug #1535165: fixed a segfault in input() and raw_input() when
941 sys.stdin is closed.
942
Thomas Heller74d36f02006-08-04 18:17:40 +0000943- On Windows, the PyErr_Warn function is now exported from
944 the Python dll again.
945
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000946- Bug #1191458: tracing over for loops now produces a line event
947 on each iteration. Fixing this problem required changing the .pyc
948 magic number. This means that .pyc files generated before 2.5c1
949 will be regenerated.
950
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000951- Bug #1333982: string/number constants were inappropriately stored
952 in the byte code and co_consts even if they were not used, ie
953 immediately popped off the stack.
954
Georg Brandle9462c72006-08-04 18:03:37 +0000955- Fixed a reference-counting problem in property().

958Library
959-------
960
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000961- Fix a bug in the ``compiler`` package that caused invalid code to be
962 generated for generator expressions.
963
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000964- The distutils version has been changed to 2.5.0. The change to
965 keep it programmatically in sync with the Python version running
966 the code (introduced in 2.5b3) has been reverted. It will continue
967 to be maintained manually as static string literal.
968
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000969- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000970 and this cannot be converted to the required C type, an exception is
971 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000972 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000973
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000974- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000975 an exception.
976
Tim Petersc10c9d02006-09-05 02:18:09 +0000977- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000978 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000979 workarounds for clocks with low resolution, to stop the code yielding
980 duplicate UUIDs.
981
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000982- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
983 before raising SystemExit, allowing IDLE to honor quit() and exit().
984
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000985- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
986
Georg Brandl7a1af772006-08-14 21:55:28 +0000987- Patch #1536071: trace.py should now find the full module name of a
988 file correctly even on Windows.
989
Georg Brandl0a7d1bb2006-08-11 07:26:10 +0000990- logging's atexit hook now runs even if the rest of the module has
991 already been cleaned up.
992
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000993- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +0000994
Neal Norwitzff4b63b2006-08-04 04:50:21 +0000995- Bug #1531405, format_exception no longer raises an exception if
996 str(exception) raised an exception.
997
Neil Schemenauer06ded092006-08-04 16:20:30 +0000998- Fix a bug in the ``compiler`` package that caused invalid code to be
999 generated for nested functions.

Georg Brandl3335a7a2006-08-14 21:42:55 +00001007- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
1008 raises the correct exceptions.
1009
Thomas Heller1ce433e2006-08-14 16:20:04 +00001010- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1011 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1012
Thomas Heller86720042006-08-14 11:17:48 +00001013- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1014 uses the _as_parameter_ attribute when objects are passed to foreign
1015 function calls. The ctypes version number was changed to 1.0.1.
1016
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001017- Bug #1530559, struct.pack raises TypeError where it used to convert.
1018 Passing float arguments to struct.pack when integers are expected
1019 now triggers a DeprecationWarning.

Martin v. Löwisa09fd6e2006-08-16 12:55:10 +00001045- Bug #1535502, build _hashlib on Windows, and use masm assembler
1046 code in OpenSSL.
1047
Thomas Hellerdb7b4432006-08-04 19:49:31 +00001048- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

1054-----
1055
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001056- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1057
Tim Peters4643c2f2006-08-10 22:45:34 +00001058- Bug #1069160. Internal correctness changes were made to
1059 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1060 the documentation was changed to state that the return value
1061 is always 1 (normal) or 0 (if the specified thread wasn't found).

1069Core and builtins
1070-----------------
1071
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001072- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001073 returned a long (see PEP 353).
1074
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001075- Bug #1515471: string.replace() accepts character buffers again.
1076
Neal Norwitz07aadb12006-07-30 06:55:48 +00001077- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1078 This provides the proper warning for struct.pack().
1079 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1080
Neal Norwitz0d62a062006-07-30 06:53:31 +00001081- Patch #1531113: Fix augmented assignment with yield expressions.
1082 Also fix a SystemError when trying to assign to yield expressions.
1083
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001084- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1085 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1086 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1087 excessive filesystem operations during imports.
1088
Tim Petersbc24eee2006-07-27 01:14:53 +00001089- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1090 operations on signed longs that are formally undefined by C.
1091 Unfortunately, at least one compiler now cares about that, so complicated
1092 the code to make that compiler happy again.
1093
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001094- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1095
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001096- Patch #1232023: Stop including current directory in search
1097 path on Windows.
1098
Neal Norwitze1fdb322006-07-21 05:32:28 +00001099- Fix some potential crashes found with failmalloc.
1100
Neal Norwitze7563102006-07-17 01:00:16 +00001101- Fix warnings reported by Klocwork's static analysis tool.
1102
Neal Norwitz84be93b2006-07-16 01:50:38 +00001103- Bug #1512814, Fix incorrect lineno's when code within a function
1104 had more than 255 blank lines.
1105
Georg Brandl9dceedb2006-07-12 15:31:17 +00001106- Patch #1521179: Python now accepts the standard options ``--help`` and
1107 ``--version`` as well as ``/?`` on Windows.
1108
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001109- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001110 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001111 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001112
Tim Peters112aad32006-07-19 00:03:19 +00001113- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001114 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001115 new ``sys._current_frames()`` returns a dictionary with one entry,
1116 mapping the faux "thread id" 0 to the current frame.
1117
Ronald Oussoren3075e162006-07-25 20:28:55 +00001118- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001119
Ronald Oussoren3075e162006-07-25 20:28:55 +00001120
Neal Norwitza1f10902006-07-12 07:28:29 +00001121Library
1122-------
1123
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001124- Correction of patch #1455898: In the mbcs decoder, set final=False
1125 for stream decoder, but final=True for the decode function.
1126
Georg Brandl07fec3a2006-08-01 18:49:24 +00001127- os.urandom no longer masks unrelated exceptions like SystemExit or
1128 KeyboardInterrupt.
1129
Tim Peters4643c2f2006-08-10 22:45:34 +00001130- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001131 shutil.copytree on Windows
1132
Georg Brandle34ac7c2006-07-30 11:07:23 +00001133- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1134 refers to file descriptors, not file objects.
1135
Tim Petersc10c9d02006-09-05 02:18:09 +00001136- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001137 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001138 #1513611, and probably others.
1139
Georg Brandledd9b0d2006-07-29 09:33:26 +00001140- Bug #1441397: The compiler module now recognizes module and function
1141 docstrings correctly as it did in Python 2.4.
1142
Tim Peters6f681472006-07-27 23:44:37 +00001143- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1144 lost that tests are sorted by name before being run. This rarely
1145 matters for well-written tests, but can create baffling symptoms if
1146 side effects from one test to the next affect outcomes. ``DocTestFinder``
1147 has been changed to sort the list of tests it returns.
1148
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001149- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001150 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001151
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001152- Bug #978833: Really close underlying socket in _socketobject.close.
1153
Georg Brandl8c036cc2006-08-20 13:15:39 +00001154- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1155 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001156
Georg Brandlcf0c1722006-07-26 07:23:32 +00001157- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1158 to recursive calls and call it with the failing package name.
1159
Martin v. Löwis0b483032006-07-25 09:53:12 +00001160- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1161
Georg Brandlc13c34c2006-07-24 14:09:56 +00001162- Patch #1515343: Fix printing of deprecated string exceptions with a
1163 value in the traceback module.
1164
Greg Ward48fae7a2006-07-23 16:05:51 +00001165- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1166
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001167- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1168
Brett Cannoncaebe222006-07-18 04:41:36 +00001169- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1170 argument tuple. For arguments where zero is illegal, the value is forced to
1171 the minimum value that is correct. This is to support an undocumented but
1172 common way people used to fill in inconsequential information in the time
1173 tuple pre-2.4.
1174
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001175- Patch #1220874: Update the binhex module for Mach-O.
1176
Barry Warsawb110bad2006-07-21 14:51:07 +00001177- The email package has improved RFC 2231 support, specifically for
1178 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1179 (name*0=<blah>) parameter continuations. This may change the types of
1180 values returned from email.message.Message.get_param() and friends.
1181 Specifically in some cases where non-encoded continuations were used,
1182 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1183 will just return the string (since non-encoded continuations don't have
1184 charset and language parts).
1185
1186 Also, whereas % values were decoded in all parameter continuations, they are
1187 now only decoded in encoded parameter parts.
1188
Ronald Oussoren3075e162006-07-25 20:28:55 +00001189- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1190
1191- Bug #1517996: IDLE now longer shows the default Tk menu when a
1192 path browser, class browser or debugger is the frontmost window on MacOS X
1193
Barry Warsaw00decd72006-07-27 23:43:15 +00001194- Patch #1520294: Support for getset and member descriptors in types.py,
1195 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1196 of an object against these built-in types and more importantly, for getting
1197 their docstrings printed in the interactive interpreter's help() function.

1201-----------------
1202
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001203- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1204 a socket operation on a socket with a timeout, the exception will be
1205 caught correctly. Previously, the exception was not caught.
1206
Thomas Heller1393d6a2006-07-28 21:43:20 +00001207- Patch #1529514: The _ctypes extension is now compiled on more
1208 openbsd target platforms.
1209
Tim Peters9cab5932006-07-28 00:30:00 +00001210- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1211 a memory leak, affecting pickles and deep copies.
1212
Tim Petersbc24eee2006-07-27 01:14:53 +00001213- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1217
Thomas Hellerce049a02006-07-14 17:51:14 +00001218- Patch #1521817: Index range checking on ctypes arrays containing
1219 exactly one element enabled again. This allows iterating over these
1220 arrays, without the need to check the array size before.
1221
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001222- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001223 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001224 /dev/null in certain cases; this is now fixed.
1225
Thomas Heller47d7a062006-07-12 08:43:47 +00001226- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1227 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001228
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001229- Because of a misspelled preprocessor symbol, ctypes was always
1230 compiled without thread support; this is now fixed.
1231
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001232- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1233 methods now allow their database parameter to be None as the
1234 sleepycat API allows.
1235
Matt Flemingec926502006-07-28 11:27:27 +00001236- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1237 bluetooth API compared with Linux and FreeBSD.
1238
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001239Tests
1240-----
1241
1242- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1243 how long the test file should take to play. Now accepts taking 2.93 secs
1244 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1245
Georg Brandl4793aa32006-07-28 18:31:39 +00001246- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1247 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1248 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +00001249
Martin v. Löwis0907f4d2006-07-30 14:09:47 +00001250Build
1251-----
1252
1253- Bug #1439538: Drop usage of test -e in configure as it is not portable.
1254
Ronald Oussoren26cad082006-08-01 21:00:57 +00001255Mac
1256---
1257
1258- PythonLauncher now works correctly when the path to the script contains
1259 characters that are treated specially by the shell (such as quotes).
1260
1261- Bug #1527397: PythonLauncher now launches scripts with the working directory
1262 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001263 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001264 expect.

1273-----------------
1274
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001275- Bug #1441486: The literal representation of -(sys.maxint - 1)
1276 again evaluates to a int object, not a long.
1277
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001278- Bug #1501934: The scope of global variables that are locally assigned
1279 using augmented assignment is now correctly determined.
1280
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001281- Bug #927248: Recursive method-wrapper objects can now safely
1282 be released.
1283
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001284- Bug #1417699: Reject locale-specific decimal point in float()
1285 and atof().
1286
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001287- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1288 omit a default "error" argument for NULL pointer. This allows
1289 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001290
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001291- Bug #1519018: 'as' is now validated properly in import statements.
1292
Neal Norwitz28746ab2006-07-09 22:14:42 +00001293- On 64 bit systems, int literals that use less than 64 bits are
1294 now ints rather than longs.
1295
Neal Norwitzed657552006-07-10 00:04:44 +00001296- Bug #1512814, Fix incorrect lineno's when code at module scope
1297 started after line 256.
1298
Tim Peters32a83612006-07-10 21:08:24 +00001299- New function ``sys._current_frames()`` returns a dict mapping thread
1300 id to topmost thread stack frame. This is for expert use, and is
1301 especially useful for debugging application deadlocks. The functionality
1302 was previously available in Fazal Majid's ``threadframe`` extension
1303 module, but it wasn't possible to do this in a wholly threadsafe way from
1304 an extension.
1305

Martin v. Löwis8d656812006-07-10 07:23:48 +00001315 environment variable to be set in order to the SDK environment
1316 for finding the compiler, include files, etc.

1321
Thomas Woutersadd19112006-07-05 11:03:49 +00001322- string.Template() now correctly handles tuple-values. Previously,
1323 multi-value tuples would raise an exception and single-value tuples would
1324 be treated as the value they contain, instead.
1325
Martin v. Löwisede77f52006-07-03 13:01:35 +00001326- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1327 even if some data are received.
1328
Martin v. Löwis45482392006-07-03 12:28:58 +00001329- Bug #1267547: Put proper recursive setup.py call into the
1330 spec file generated by bdist_rpm.
1331
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001332- Bug #1514693: Update turtle's heading when switching between
1333 degrees and radians.
1334
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001335- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001336 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001337

1339 is created.
1340
Martin v. Löwis7596e832006-07-01 15:33:37 +00001341- Bug #1513223: .close() of a _socketobj now releases the underlying
1342 socket again, which then gets closed as it becomes unreferenced.
1343
Fred Drake10497c82006-06-29 02:57:48 +00001344- Bug #1504333: Make sgmllib support angle brackets in quoted
1345 attribute values.
1346
1347- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1348 sgmllib ('[' and ']' were not accepted).
1349
Georg Brandl1be63af2006-06-28 20:23:25 +00001350- Fix a bug in the turtle module's end_fill function.
1351
Brett Cannon53ab5b72006-06-22 16:49:14 +00001352- Bug #1510580: The 'warnings' module improperly required that a Warning
1353 category be either a types.ClassType and a subclass of Warning. The proper
1354 check is just that it is a subclass with Warning as the documentation states.
1355
Georg Brandlad29e632006-06-21 17:45:17 +00001356- The compiler module now correctly compiles the new try-except-finally
1357 statement (bug #1509132).
1358
Neal Norwitz60373cd2006-06-22 06:30:50 +00001359- The wsgiref package is now installed properly on Unix.
1360
Vinay Sajip28e57612006-07-01 10:45:20 +00001361- A bug was fixed in logging.config.fileConfig() which caused a crash on
1362 shutdown when fileConfig() was called multiple times.
1363
Gerhard Häring762fbd32006-07-02 17:48:30 +00001364- The sqlite3 module did cut off data from the SQLite database at the first
1365 null character before sending it to a custom converter. This has been fixed
1366 now.
1367
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001368Extension Modules
1369-----------------
1370
Tim Peters112aad32006-07-19 00:03:19 +00001371- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1372 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1373 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001374
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001375- Assigning None to pointer type fields in ctypes structures possible
1376 overwrote the wrong fields, this is fixed now.
1377
1378- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1379 on non-Windows platforms.
1380
1381- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1382 integer or long, without range checking.
1383
1384- Patch #1517790: It is now possible to use custom objects in the ctypes
1385 foreign function argtypes sequence as long as they provide a from_param
1386 method, no longer is it required that the object is a ctypes type.
1387
1388- The '_ctypes' extension module now works when Python is configured
1389 with the --without-threads option.
1390
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001391- Bug #1513646: os.access on Windows now correctly determines write
1392 access, again.
1393
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001394- Bug #1512695: cPickle.loads could crash if it was interrupted with
1395 a KeyboardInterrupt.

Neal Norwitza12aa882006-07-06 06:45:08 +00001397- Bug #1296433: parsing XML with a non-default encoding and
1398 a CharacterDataHandler could crash the interpreter in pyexpat.
1399

1406
Tim Peters32a83612006-07-10 21:08:24 +00001407- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001408 Previously, the slight difference could cause compilation errors of the
1409 'zlib' module on systems with more than one version of zlib.
1410
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001411- The MSI compileall step was fixed to also support a TARGETDIR
1412 with spaces in it.

1427-------------
1428
Nick Coghlan2d792252006-07-06 13:47:18 +00001429- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1430 documentation for the warnings module.
1431
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001432- Patch #1509163: MS Toolkit Compiler no longer available.

1443-----------------
1444
Georg Brandla56b9152006-06-19 06:35:54 +00001445- Patch #1507676: Error messages returned by invalid abstract object operations
1446 (such as iterating over an integer) have been improved and now include the
1447 type of the offending object to help with debugging.
1448
Brett Cannonea3912b2006-06-13 21:46:41 +00001449- Bug #992017: A classic class that defined a __coerce__() method that returned
1450 its arguments swapped would infinitely recurse and segfault the interpreter.
1451
Neal Norwitz909eb122006-06-12 02:13:21 +00001452- Fix the socket tests so they can be run concurrently.
1453
Neal Norwitzb9845e72006-06-12 02:11:18 +00001454- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001455 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001456
Brett Cannon22565aa2006-06-09 22:31:23 +00001457- Bug #532646: object.__call__() will continue looking for the __call__
1458 attribute on objects until one without one is found. This leads to recursion
1459 when you take a class and set its __call__ attribute to an instance of the
1460 class. Originally fixed for classic classes, but this fix is for new-style.
1461 Removes the infinite_rec_3 crasher.
1462
Georg Brandl24250812006-06-09 18:45:48 +00001463- The string and unicode methods startswith() and endswith() now accept
1464 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1465
Brett Cannonde3b0522006-06-08 17:00:45 +00001466- Buffer objects, at the C level, never used the char buffer
1467 implementation even when the char buffer for the wrapped object was
1468 explicitly requested (originally returned the read or write buffer).
1469 Now a TypeError is raised if the char buffer is not present but is
1470 requested.
1471
Georg Brandlddbaa662006-06-04 21:56:52 +00001472- Patch #1346214: Statements like "if 0: suite" are now again optimized
1473 away like they were in Python 2.4.
1474
Georg Brandlb7c8f542006-05-27 12:30:25 +00001475- Builtin exceptions are now full-blown new-style classes instead of
1476 instances pretending to be classes, which speeds up exception handling
1477 by about 80% in comparison to 2.5a2.
1478
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001479- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1480 Unicode 4.1.
1481
Georg Brandlf4ef1162006-05-26 18:03:31 +00001482- Patch #921466: sys.path_importer_cache is now used to cache valid and
1483 invalid file paths for the built-in import machinery which leads to
1484 fewer open calls on startup.
1485
Tim Peters696cf432006-05-24 21:10:40 +00001486- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1487 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1488 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1489 the number of input digits (it was and remains linear-time for bases
1490 2, 4, 8, 16 and 32).
1491
Tim Petersb713ec22006-05-23 18:45:30 +00001492- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1493 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1494 an integer close to ``sys.maxint``. This was repaired by patch
1495 #1335972, which also gives a nice speedup.
1496
Richard Jonescebbefc2006-05-23 18:28:17 +00001497- Patch #1337051: reduced size of frame objects.
1498
1499- PyErr_NewException now accepts a tuple of base classes as its
1500 "base" parameter.
1501
Richard Jones7c88dcc2006-05-23 10:37:38 +00001502- Patch #876206: function call speedup by retaining allocated frame
1503 objects.
1504
Georg Brandl7b90e162006-05-18 07:01:27 +00001505- Bug #1462152: file() now checks more thoroughly for invalid mode
1506 strings and removes a possible "U" before passing the mode to the
1507 C library function.
1508
Neal Norwitz1004a532006-05-15 07:17:23 +00001509- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1510
Neal Norwitz373f0a72006-05-15 07:04:36 +00001511- Bug #1487966: Fix SystemError with conditional expression in assignment
1512
Martin v. Löwis879768d2006-05-11 13:28:43 +00001513- WindowsError now has two error code attributes: errno, which carries
1514 the error values from errno.h, and winerror, which carries the error
1515 values from winerror.h. Previous versions put the winerror.h values
1516 (from GetLastError()) into the errno attribute.
1517
Martin v. Löwis77736712006-05-04 05:51:03 +00001518- Patch #1475845: Raise IndentationError for unexpected indent.
1519
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001520- Patch #1479181: split open() and file() from being aliases for each other.
1521
Tim Peters44bd9862006-06-01 13:49:23 +00001522- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1523 methods were always silently ignored by dictionaries when comparing keys.
1524 They are now passed through (except when using the C API function
1525 ``PyDict_GetItem()``, whose semantics did not change).
1526
1527- Bug #1456209: In some obscure cases it was possible for a class with a
1528 custom ``__eq__()`` method to confuse dict internals when class instances
1529 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1530 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001532Extension Modules
1533-----------------
1534
Trent Mick960a3f82006-06-28 20:30:41 +00001535- Bug #1295808: expat symbols should be namespaced in pyexpat
1536
1537- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1538
Brett Cannon6ee7d012006-06-08 16:23:04 +00001539- Change binascii.hexlify to accept a read-only buffer instead of only a char
1540 buffer and actually follow its documentation.
1541
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001542- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1543
Nick Coghlanc649ec52006-05-29 12:43:05 +00001544- Patch #1478788 (modified version): The functional extension module has
1545 been renamed to _functools and a functools Python wrapper module added.
1546 This provides a home for additional function related utilities that are
1547 not specifically about functional programming. See PEP 309.
1548
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001549- Patch #1493701: performance enhancements for struct module.
1550
Georg Brandl378d5922006-05-17 14:26:50 +00001551- Patch #1490224: time.altzone is now set correctly on Cygwin.
1552
Georg Brandl8d3342b2006-05-16 07:38:27 +00001553- Patch #1435422: zlib's compress and decompress objects now have a
1554 copy() method.
1555
Andrew MacIntyre92913322006-06-13 15:04:24 +00001556- Patch #1454481: thread stack size is now tunable at runtime for thread
1557 enabled builds on Windows and systems with Posix threads support.
1558
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001559- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1560 (up to the system limit of 32K characters).
1561
1562- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1563 As a result, these functions now raise WindowsError instead of OSError.
1564
Tim Peters7a822da2006-05-25 21:50:17 +00001565- ``time.clock()`` on Win64 should use the high-performance Windows
1566 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1567 Windows platforms).
1568
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001569- Calling Tk_Init twice is refused if the first call failed as that
1570 may deadlock.
1571
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001572- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1573 accept it without potentially using an uninitialized pointer.
1574
1575- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1576 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1577 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001578
Gregory P. Smith372b5832006-06-05 18:48:21 +00001579- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001580 [pybsddb project SF patch number 1466734]
1581
Gregory P. Smith372b5832006-06-05 18:48:21 +00001582- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1583 parameter is supplied. [SF pybsddb bug #1477863]
1584
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001585- bsddb: the __len__ method of a DB object has been fixed to return correct
1586 results. It could previously incorrectly return 0 in some cases.
1587 Fixes SF bug 1493322 (pybsddb bug 1184012).
1588
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001589- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1590 aborts the db transaction safely when a modifier callback fails.
1591 Fixes SF python patch/bug #1408584.
1592
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001593- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001594 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001595 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1596 database calls that would previously deadlock. [SF python bug #775414]
1597
Vinay Sajip28e57612006-07-01 10:45:20 +00001598- Patch #1446489: add support for the ZIP64 extensions to zipfile.

Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001606- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1607 functions.
1608
Martin v. Löwis3798da02006-06-17 18:44:27 +00001609- Patch #812986: Update turtle output even if not tracing.
1610
Vinay Sajip28e57612006-07-01 10:45:20 +00001611- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001612 Tkinter.BaseWidget.
1613
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001614- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1615
Martin v. Löwis337487e2006-06-17 09:15:14 +00001616- Patch #763580: Add name and value arguments to Tkinter variable
1617 classes.
1618
Georg Brandl83cc0d02006-06-14 08:50:03 +00001619- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1620 mime.types file for determining MIME types.
1621
Georg Brandl2605ca82006-06-14 06:08:31 +00001622- Bug #1339007: Shelf objects now don't raise an exception in their
1623 __del__ method when initialization failed.
1624
Martin v. Löwisd8251432006-06-14 05:21:04 +00001625- Patch #1455898: The MBCS codec now supports the incremental mode for
1626 double-byte encodings.
1627
Tim Peters43898b42006-06-14 04:09:25 +00001628- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1629 guarantee that adjacent triples in the return list always describe
1630 non-adjacent blocks. Previously, a pair of matching blocks could end
1631 up being described by multiple adjacent triples that formed a partition
1632 of the matching pair.
1633
Greg Ward0e0c9f42006-06-11 16:24:11 +00001634- Bug #1498146: fix optparse to handle Unicode strings in option help,
1635 description, and epilog.
1636
Greg Wardd1c797e2006-06-11 14:42:41 +00001637- Bug #1366250: minor optparse documentation error.
1638
Greg Ward7f547402006-06-11 00:40:49 +00001639- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1640 clarify docs.
1641
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001642- The wsgiref package has been added to the standard library.
1643
Nick Coghlan676725d2006-06-08 13:54:49 +00001644- The functions update_wrapper() and wraps() have been added to the functools
1645 module. These make it easier to copy relevant metadata from the original
1646 function when writing wrapper functions.
1647
Tim Petersd6a9eef2006-06-05 01:48:21 +00001648- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1649 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001650
Martin v. Löwis3f767792006-06-04 19:36:28 +00001651- Patch #1359618: Speed up charmap encoder by using a trie structure
1652 for lookup.
1653
Tim Petersd609b1a2006-06-02 23:22:51 +00001654- The functions in the ``pprint`` module now sort dictionaries by key
1655 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1656 if and only if its display required more than one line, although that
1657 wasn't documented. The new behavior increases predictability; e.g.,
1658 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1659
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001660- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1661 (thanks for J. J. Lee).
1662
Georg Brandl2b330372006-05-28 20:23:12 +00001663- Patch #1496206: improve urllib2 handling of passwords with respect to
1664 default HTTP and HTTPS ports.
1665
George Yoshidaf3c65de2006-05-28 16:39:09 +00001666- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1667
Bob Ippolito7298f272006-05-23 18:43:47 +00001668- Patch #1281707: speed up gzip.readline.
1669
Georg Brandlb89316f2006-05-17 15:51:16 +00001670- Patch #1180296: Two new functions were added to the locale module:
1671 format_string() to get the effect of "format % items" but locale-aware,
1672 and currency() to format a monetary number with currency sign.
1673
Georg Brandle3a25832006-05-17 14:56:04 +00001674- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1675 and several features added, such as speed and geometry control.
1676
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001677- Patch #1488881: add support for external file objects in bz2 compressed
1678 tarfiles.
1679
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001680- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1681 stdout arguments, making it possible to redirect input and output
1682 for remote debugging.
1683
1684- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1685 a couple of issues, notably handling of long file names using the
1686 GNU LONGNAME extension.
1687
1688- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1689 new flag when ``name`` is already the name of an option flag.
1690
1691- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1692 package.
1693
1694- Patch #1472854: make the rlcompleter.Completer class usable on non-
1695 UNIX platforms.
1696
1697- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1698
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001699- Bug #1472827: correctly escape newlines and tabs in attribute values in

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001730What's New in Python 2.5 alpha 2?

1732
1733*Release date: 27-APR-2006*
1734
1735Core and builtins
1736-----------------
1737
Thomas Heller1b046642006-04-18 18:51:06 +00001738- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1739 by converting these apis from macros into exported functions again:
1740
1741 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1742 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1743 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne

1745 PyRun_String Py_CompileString
1746
Martin v. Löwis45294a92006-04-18 06:24:08 +00001747- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1748
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001749- All uses of PyStructSequence_InitType have been changed to initialize
1750 the type objects only once, even if the interpreter is initialized
1751 multiple times.
1752
Neal Norwitz61546162006-04-14 05:20:28 +00001753- Bug #1454485, array.array('u') could crash the interpreter. This was
1754 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1755 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1756
1757- Py_UNICODE is unsigned. It was always documented as unsigned, but
1758 due to a bug had a signed value in previous versions.
1759
Tim Peters3a5e8b12006-04-11 01:44:07 +00001760- Patch #837242: ``id()`` of any Python object always gives a positive
1761 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1762 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001763 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001764 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001765
Tim Peters3a5e8b12006-04-11 01:44:07 +00001766 def __hash__(self):
1767 return id(self) # WRONG
1768
1769 because a hash result must be a (short) Python int but it was always
1770 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001771 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001772 was always usable as a hash value before this patch. That's no longer
1773 necessarily so.
1774
1775- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001776 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001777 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001778 #1454844)
1779
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001780- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1781 involving generators that have paused outside of any ``try`` or ``with``
1782 blocks. (In 2.5a1, a paused generator that was part of a reference
1783 cycle could not be garbage collected, regardless of whether it was
1784 paused in a ``try`` or ``with`` block.)

1797- Bug #1117761: bsddb.*open() no longer raises an exception when using
1798 the cachesize parameter.
1799
1800- Bug #1149413: bsddb.*open() no longer raises an exception when using
1801 a temporary db (file=None) with the 'n' flag to truncate on open.
1802
1803- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1804 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001805
Armin Rigoa9017c32006-04-19 11:50:27 +00001806- Patch #1062014: AF_UNIX sockets under Linux have a special

1811
Peter Astrand7d1d4362006-07-14 14:04:45 +00001812- Bug #1223937: subprocess.CalledProcessError reports the exit status
1813 of the process using the returncode attribute, instead of
1814 abusing errno.
1815
Tim Peters711bf302006-04-25 03:31:36 +00001816- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1817 a doctest to be skipped (the code is not run, and the expected output
1818 or exception is ignored).
1819
Nick Coghlanda2268f2006-04-24 04:37:15 +00001820- Fixed contextlib.nested to cope with exceptions being raised and
1821 caught inside exit handlers.
1822
Greg Wardab05edc2006-04-23 03:47:58 +00001823- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1824 hex, octal, or binary; add ``append_const`` action; keep going if
1825 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1826 added ``epilog`` for better help generation).
1827
Tim Peters21fbd572006-04-21 21:18:10 +00001828- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1829 called from a thread spawned as a side effect of importing a module.
1830
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001831- The pydoc module now supports documenting packages contained in
1832 .zip or .egg files.
1833
1834- The pkgutil module now has several new utility functions, such
1835 as ``walk_packages()`` to support working with packages that are either
1836 in the filesystem or zip files.
1837
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001838- The mailbox module can now modify and delete messages from
1839 mailboxes, in addition to simply reading them. Thanks to Gregory
1840 K. Johnson for writing the code, and to the 2005 Google Summer of
1841 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001842
Tim Petersc7605f22006-04-17 21:12:33 +00001843- The ``__del__`` method of class ``local`` in module ``_threading_local``

Anthony Baxtere29002c2006-04-12 12:07:31 +00001852- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1853 Windows. Bug #1469163.
1854
Phillip J. Eby47032112006-04-11 01:07:43 +00001855- The warnings, linecache, inspect, traceback, site, and doctest modules

1865
Skip Montanaro262fb922006-04-21 02:31:07 +00001866- The pstats.Stats class accepts an optional stream keyword argument to
1867 direct output to an alternate file-like object.
1868
Anthony Baxter51bcb682006-04-05 14:51:42 +00001869Build
1870-----
1871
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001872- The Makefile now has a reindent target, which runs reindent.py on
1873 the library.
1874
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001875- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001878
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001879- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1880 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001881 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001882 CXX from --with-cxx-main, see description in README.
1883
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001884- Patch #1429775: Link extension modules with the shared libpython.
1885
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001886- Fixed a libffi build problem on MIPS systems.
1887
Tim Peters8931ff12006-05-13 23:28:20 +00001888- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1889 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1890 and "%zu" for unsigned integers of type ``size_t``.
1891
Anthony Baxter51bcb682006-04-05 14:51:42 +00001892Tests
1893-----
1894
Nick Coghlanda2268f2006-04-24 04:37:15 +00001895- test_contextlib now checks contextlib.nested can cope with exceptions
1896 being raised and caught inside exit handlers.
1897
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001898- test_cmd_line now checks operation of the -m and -c command switches
1899
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001900- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1901 it separately and by hand. It also wasn't cleaning up its changes to
1902 the current Decimal context.
1903
Thomas Woutersabd08882006-04-26 15:53:30 +00001904- regrtest.py now has a -M option to run tests that test the new limits of
1905 containers, on 64-bit architectures. Running these tests is only sensible
1906 on 64-bit machines with more than two gigabytes of memory. The argument
1907 passed is the maximum amount of memory for the tests to use.

1916-------------
1917
Tim Petersb06d28c2006-05-12 01:57:59 +00001918- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1919
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001920- PEP 343: Added Context Types section to the library reference
1921 and attempted to bring other PEP 343 related documentation into
1922 line with the implementation and/or python-dev discussions.
1923
Tim Peters8dc73d22006-04-24 02:03:16 +00001924- Bug #1337990: clarified that ``doctest`` does not support examples
1925 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001928What's New in Python 2.5 alpha 1?
1929=================================
1930
Anthony Baxterebed3f62006-04-03 15:03:44 +00001931*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001932
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001933Core and builtins
1934-----------------
1935
Nick Coghlan43832302006-04-23 17:04:07 +00001936- PEP 338: -m command line switch now delegates to runpy.run_module
1937 allowing it to support modules in packages and zipfiles
1938
Martin v. Löwisc661b882006-04-20 04:54:23 +00001939- On Windows, .DLL is not an accepted file name extension for
1940 extension modules anymore; extensions are only found if they
1941 end in .PYD.
1942
Martin v. Löwisea62d252006-04-03 10:56:49 +00001943- Bug #1421664: sys.stderr.encoding is now set to the same value as
1944 sys.stdout.encoding.
1945
Neal Norwitz92e212f2006-04-03 04:48:37 +00001946- __import__ accepts keyword arguments.
1947
Georg Brandlccadf842006-03-31 18:54:53 +00001948- Patch #1460496: round() now accepts keyword arguments.
1949
Anthony Baxter262c00a2006-03-30 10:53:17 +00001950- Fixed bug #1459029 - unicode reprs were double-escaped.
1951
Hye-Shik Changd478f342006-03-23 12:32:36 +00001952- Patch #1396919: The system scope threads are reenabled on FreeBSD
1953 5.4 and later versions.
1954
Neal Norwitze98ccf62006-03-23 05:39:47 +00001955- Bug #1115379: Compiling a Unicode string with an encoding declaration
1956 now gives a SyntaxError.
1957
Georg Brandlabd1ff82006-03-18 07:59:59 +00001958- Previously, Python code had no easy way to access the contents of a
1959 cell object. Now, a ``cell_contents`` attribute has been added
1960 (closes patch #1170323).
1961
Tim Peterscf79aac2006-03-16 01:14:46 +00001962- Patch #1123430: Python's small-object allocator now returns an arena to
1963 the system ``free()`` when all memory within an arena becomes unused
1964 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1965 freed. Some applications will see a drop in virtual memory size now,
1966 especially long-running applications that, from time to time, temporarily
1967 use a large number of small objects. Note that when Python returns an
1968 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001969 platform C library will in turn return that memory to the operating system.
1970 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001971 appears to be effective at least on Microsoft C and gcc-based systems.
1972 Thanks to Evan Jones for hard work and patience.
1973
Georg Brandl533ff6f2006-03-08 18:09:27 +00001974- Patch #1434038: property() now uses the getter's docstring if there is
1975 no "doc" argument given. This makes it possible to legitimately use
1976 property() as a decorator to produce a read-only property.
1977
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001978- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1979 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1980 of requiring an int or long in slicing and a few other contexts, enabling
1981 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1982
Neal Norwitz995acdf2006-03-07 05:01:00 +00001983- Fixed various bugs reported by Coverity's Prevent tool.
1984
Brett Cannonbf364092006-03-01 04:25:17 +00001985- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
1986 new exception base class, BaseException, which has a new message attribute.
1987 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
1988 Raising a string exception now raises a DeprecationWarning.
1989
Thomas Woutersfb609f42006-02-28 16:37:25 +00001990- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
1991 explicitly relative, using 'from .module import name' to mean 'from the same
1992 package as this module is in. Imports without dots still default to the
1993 old relative-then-absolute, unless 'from __future__ import
1994 absolute_import' is used.
1995
Brett Cannona7446e32006-02-27 23:39:10 +00001996- Properly check if 'warnings' raises an exception (usually when a filter set
1997 to "error" is triggered) when raising a warning for raising string
1998 exceptions.
1999
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002000- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002001 The name was removed from Include/code.h.
2002
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002003- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002004
Guido van Rossum1968ad32006-02-25 22:38:04 +00002005- Patch 1433928:
2006 - The copy module now "copies" function objects (as atomic objects).
2007 - dict.__getitem__ now looks for a __missing__ hook before raising
2008 KeyError.
2009
Tim Peters84ef21c2006-02-28 20:39:06 +00002010- PEP 343: with statement implemented. Needs ``from __future__ import
2011 with_statement``. Use of 'with' as a variable will generate a warning.
2012 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002013 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002014 The following objects have __context__ methods:
2015 - The built-in file type.
2016 - The thread.LockType type.
2017 - The following types defined by the threading module:
2018 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2019 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002020
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002021- Fix the encodings package codec search function to only search
2022 inside its own package. Fixes problem reported in patch #1433198.
2023
2024 Note: Codec packages should implement and register their own
2025 codec search function. PEP 100 has the details.
2026
Tim Peters9ea89d22006-06-04 03:26:02 +00002027- PEP 353: Using ``Py_ssize_t`` as the index type.
2028
2029- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2030 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2031 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2032 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2033 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002034
Neal Norwitzfc76d632006-01-10 06:03:13 +00002035- Patch #1400181, fix unicode string formatting to not use the locale.
2036 This is how string objects work. u'%f' could use , instead of .
2037 for the decimal point. Now both strings and unicode always use periods.
2038
Neal Norwitz671b9e32006-01-09 07:07:12 +00002039- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2040 configure would break checking curses.h.
2041
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002042- Bug #959576: The pwd module is now builtin. This allows Python to be
2043 built on UNIX platforms without $HOME set.
2044
Neal Norwitzc10978f2005-12-19 06:07:16 +00002045- Bug #1072182, fix some potential problems if characters are signed.
2046
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002047- Bug #889500, fix line number on SyntaxWarning for global declarations.
2048
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002049- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2050
Neal Norwitze7214a12005-12-18 05:03:17 +00002051- Support for converting hex strings to floats no longer works.
2052 This was not portable. float('0x3') now raises a ValueError.
2053
Barry Warsaw2a38a862005-12-18 01:27:35 +00002054- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002055 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002056 is now displayed in interactive prompt banner.

Georg Brandlfa166682005-12-17 21:45:17 +00002058- Implementation of PEP 341 - Unification of try/except and try/finally.
2059 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002060 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002061
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002062- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2063 now encodes backslash correctly.
2064
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002065- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2066
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002067- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002068 and long longs.
2069
Neal Norwitz67715f02005-11-09 06:59:35 +00002070- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002071 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002072 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002073
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002074- Replaced most Unicode charmap codecs with new ones using the
2075 new Unicode translate string feature in the builtin charmap
2076 codec; the codecs were created from the mapping tables available
2077 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2078 encodings now include a mapping for the Apple logo)
2079
Tim Peterse3547fd2005-12-16 23:13:57 +00002080- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002081
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002082- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002083
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002084- A new AST parser implementation was completed. The abstract
2085 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002086 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002087
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002088- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002089 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2090
Neal Norwitz708e51a2005-10-03 04:48:15 +00002091- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2092
Neal Norwitz11bd1192005-10-03 00:54:56 +00002093- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2094 Provide a warning when a directory is passed on the command line.
2095
Neal Norwitz40d37812005-10-02 01:48:49 +00002096- Fix segfault with invalid coding.
2097
2098- SF bug #772896: unknown encoding results in MemoryError.
2099
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002100- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002101 supported a __len__() method which evaluated to False when the iterator
2102 was empty.
2103
Guido van Rossum630db602005-09-20 18:49:54 +00002104- On 64-bit platforms, when __len__() returns a value that cannot be
2105 represented as a C int, raise OverflowError.
2106
Skip Montanarof8948ca2005-09-19 03:54:46 +00002107- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002108 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002109
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002110- SF bug #893549: parsing keyword arguments was broken with a few format
2111 codes.
2112
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002113- Changes donated by Elemental Security to make it work on AIX 5.3
2114 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2115 bug #105470: test_pwd fails on 64bit system (Opteron).
2116
Guido van Rossum539c6622005-09-14 17:49:54 +00002117- Changes donated by Elemental Security to make it work on HP-UX 11 on
2118 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2119
Georg Brandl4550b8d2005-08-26 06:43:52 +00002120- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002121 (fixes bug #1119418).
2122
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002123- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2124
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002125- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2126 exceptions that cause a function to exit.
2127
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002128- The implementation of set() and frozenset() was revised to use its
2129 own internal data structure. Memory consumption is reduced by 1/3
2130 and there are modest speed-ups as well. The API is unchanged.
2131
Tim Petersde7990b2005-07-17 23:45:23 +00002132- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2133
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002134- SF bug #1229429: PyObject_CallMethod failed to decrement some
2135 reference counts in some error exit cases.
2136
Tim Petersecc6e6a2005-07-10 22:30:55 +00002137- SF bug #1185883: Python's small-object memory allocator took over
2138 a block managed by the platform C library whenever a realloc specified
2139 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002140 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002141 portable way to copy data from the C-managed block into Python's
2142 small-object space without risking a memory fault. Python's small-object
2143 realloc now leaves such blocks under the control of the platform C
2144 realloc.
2145
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002146- SF bug #1232517: An overflow error was not detected properly when
2147 attempting to convert a large float to an int in os.utime().
2148
Raymond Hettinger3296e692005-06-29 23:29:56 +00002149- SF bug #1224347: hex longs now print with lowercase letters just
2150 like their int counterparts.
2151
Michael W. Hudson188d4362005-06-20 16:52:57 +00002152- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2153 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2154 interpreter states; back out that fix and do a better job (see
2155 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2156 for a longer write-up of the problem).
2157
Michael W. Hudsondf888462005-06-03 14:41:55 +00002158- SF patch #1180995: marshal now uses a binary format by default when
2159 serializing floats.
2160
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002161- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2162 the routines that promise to produce IEEE 754 binary representations
2163 of floats now simply copy bytes around.
2164
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002165- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2166 278.
2167
Brett Cannonc3647ac2005-04-26 03:45:26 +00002168- patch #1109424: int, long, float, complex, and unicode now check for the
2169 proper magic slot for type conversions when subclassed. Previously the
2170 magic slot was ignored during conversion. Semantics now match the way
2171 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002172 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002173 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002174 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002175
Barry Warsawc8d907c2005-04-19 23:43:40 +00002176- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2177 NULL, now raise an AttributeError when attempting to set or delete the
2178 attribute. Previously a TypeError was raised, but this was inconsistent
2179 with the equivalent pure-Python implementation.
2180
Michael W. Hudson774479c2005-04-18 08:46:17 +00002181- It is now safe to call PyGILState_Release() before
2182 PyEval_InitThreads() (note that if there is reason to believe there
2183 are multiple threads around you still must call PyEval_InitThreads()
2184 before using the Python API; this fix is for extension modules that
2185 have no way of knowing if Python is multi-threaded yet).
2186
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002187- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2188 disabled caused a crash.
2189
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002190- Bug #1165306: instancemethod_new allowed the creation of a method
2191 with im_class == im_self == NULL, which caused a crash when called.
2192
Tim Petersecc6e6a2005-07-10 22:30:55 +00002193- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002194 fixes the crash seen in bug #1165761
2195
Raymond Hettinger96229b12005-03-11 06:49:40 +00002196- Added two new builtins, any() and all().
2197
Brett Cannon409d8f22005-03-05 06:47:57 +00002198- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002199 (e.g., ``class C(): pass`` is no longer a syntax error).
2200 Patch #1176012 added support to the 'parser' module and 'compiler' package
2201 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002202
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002203- Patch #1115086: Support PY_LONGLONG in structmember.
2204
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002205- Bug #1155938: new style classes did not check that __init__() was
2206 returning None.
2207
Tim Petersecc6e6a2005-07-10 22:30:55 +00002208- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002209 ('\') with a specific error message.
2210
Martin v. Löwisff232d72005-03-03 09:24:38 +00002211- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2212
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002213- Bug #1124295: the __name__ attribute of file objects was
2214 inadvertently made inaccessible in restricted mode.
2215
Tim Petersecc6e6a2005-07-10 22:30:55 +00002216- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002217 an ferror() call.
2218
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002219- min() and max() now support key= arguments with the same meaning as in
2220 list.sort().
2221
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002222- The peephole optimizer now performs simple constant folding in expressions:
2223 (2+3) --> (5).
2224
Raymond Hettingera422c342005-01-11 03:03:27 +00002225- set and frozenset objects can now be marshalled. SF #1098985.
2226
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002227- Bug #1077106: Poor argument checking could cause memory corruption
2228 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002229
Jeremy Hyltonab630502005-02-04 18:44:06 +00002230- The parser did not complain about future statements in illegal
2231 positions. It once again reports a syntax error if a future
2232 statement occurs after anything other than a doc string.
2233
Neil Schemenauercf52c072005-08-12 17:34:58 +00002234- Change the %s format specifier for str objects so that it returns a
2235 unicode instance if the argument is not an instance of basestring and
2236 calling __str__ on the argument returns a unicode instance.
2237
Tim Petersf4e69282006-02-27 17:15:31 +00002238- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2239 current thread state when the auto-GIL-state machinery knows about
2240 it (since the thread state is being deleted, continuing to remember it
2241 can't help, but can hurt if another thread happens to get created with
2242 the same thread id).
2243
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002244Extension Modules
2245-----------------
2246
Georg Brandl43f08a82006-03-31 18:01:16 +00002247- Patch #1380952: fix SSL objects timing out on consecutive read()s

Georg Brandlbc45a3f2006-03-17 19:17:34 +00002256
Neal Norwitz10be10c2006-03-16 06:50:13 +00002257- Everything under lib-old was removed. This includes the following modules:
2258 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00002259 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00002260 util, whatsound, whrandom, zmod
2261
2262- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2263
2264- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002265 is deprecated. The undocumented re.engine variable no longer exists.
2266
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002267- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2268 SS2 (single-shift 2) escape sequences correctly.
2269
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002270- The unicodedata module was updated to the 4.1 version of the Unicode
2271 database. The 3.2 version is still available as unicodedata.db_3_2_0
2272 for applications that require this specific version (such as IDNA).
2273
Neal Norwitzb62c4332006-03-04 18:35:47 +00002274- The timing module is no longer built by default. It was deprecated
2275 in PEP 4 in Python 2.0 or earlier.
2276
Guido van Rossum1968ad32006-02-25 22:38:04 +00002277- Patch 1433928: Added a new type, defaultdict, to the collections module.
2278 This uses the new __missing__ hook behavior added to dict (see above).
2279
Georg Brandldbd83392006-02-20 09:42:33 +00002280- Bug #854823: socketmodule now builds on Sun platforms even when
2281 INET_ADDRSTRLEN is not defined.
2282
Georg Brandlf4f44152006-02-18 22:29:33 +00002283- Patch #1393157: os.startfile() now has an optional argument to specify
2284 a "command verb" to invoke on the file.
2285
Neal Norwitz082b2df2006-02-07 07:04:46 +00002286- Bug #876637, prevent stack corruption when socket descriptor
2287 is larger than FD_SETSIZE.
2288
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00002289- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
2290 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
2291 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
2292
Martin v. Löwis57a34e82006-02-04 19:12:37 +00002293- Patch #1422385: The nis module now supports access to domains other
2294 than the system default domain.
2295
Martin v. Löwis14694662006-02-03 12:54:16 +00002296- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2297 are reported, the limit on path name lengths is removed, and stat reports
2298 WindowsError now (instead of OSError).
2299
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002300- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.
2301
Neal Norwitz62a21122006-01-25 05:21:55 +00002302- Bug #1413192, fix seg fault in bsddb if a transaction was deleted
2303 before the env.
2304
Martin v. Löwis11017b12006-01-14 18:12:57 +00002305- Patch #1103116: Basic AF_NETLINK support.
2306
Neal Norwitz3b4fff82006-01-11 08:54:45 +00002307- Bug #1402308, (possible) segfault when using mmap.mmap(-1, ...)
2308
Neal Norwitz88bbd732006-01-10 07:05:44 +00002309- Bug #1400822, _curses over{lay,write} doesn't work when passing 6 ints.
2310 Also fix ungetmouse() which did not accept arguments properly.
2311 The code now conforms to the documented signature.
2312
Neal Norwitz5e3d8622006-01-09 06:24:35 +00002313- Bug #1400115, Fix segfault when calling curses.panel.userptr()
2314 without prior setting of the userptr.
2315
Neal Norwitz40c6b472006-01-05 05:43:35 +00002316- Fix 64-bit problems in bsddb.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002434- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2435 been renamed to have only a single underscore prefix. This was done to
2436 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002437
Nick Coghlan43832302006-04-23 17:04:07 +00002438- PEP 338: new module runpy defines a run_module function to support
2439 executing modules which provide access to source code or a code object
2440 via the PEP 302 import mechanisms.
2441
Anthony Baxter93f5b932006-04-03 08:05:07 +00002442- The email module's parsedate_tz function now sets the daylight savings
2443 flag to -1 (unknown) since it can't tell from the date whether it should

2450 in attribute values.
2451
Anthony Baxterc51ee692006-04-01 00:57:31 +00002452- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002453 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002454 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002455 module will not be built.
2456
Tim Petersc17976e2006-04-01 00:26:53 +00002457- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2458 aren't officially supported here, and trying to use them will probably
2459 raise an exception some day. But dicts have been allowed, and "mostly
2460 worked", so support for them won't go away without warning.
2461
Georg Brandl338ef7d2006-03-31 18:42:16 +00002462- Bug #1445068: getpass.getpass() can now be given an explicit stream
2463 argument to specify where to write the prompt.
2464
Georg Brandl22ec80b2006-03-31 18:25:44 +00002465- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2472
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002473- Queue.Queue objects now support .task_done() and .join() methods
2474 to make it easier to monitor when daemon threads have completed
2475 processing all enqueued tasks. Patch #1455676.
2476

2480
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002481- email 4.0 package now integrated. This is largely the same as the email 3.0
2482 package that was included in Python 2.3, except that PEP 8 module names are
2483 now used (e.g. mail.message instead of email.Message). The MIME classes
2484 have been moved to a subpackage (e.g. email.mime.text instead of
2485 email.MIMEText). The old names are still supported for now. Several
2486 deprecated Message methods have been removed and lots of bugs have been
2487 fixed. More details can be found in the email package documentation.
2488
Walter Dörwald40108c92006-03-27 08:15:44 +00002489- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2490 (a subclass of tuple) that provides incremental decoders and encoders
2491 (a way to use stateful codecs without the stream API). Python functions
2492 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2493 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2494 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002495
Walter Dörwald067db482006-03-15 22:17:27 +00002496- Patch #1359365: Calling next() on a closed StringIO.String object raises
2497 a ValueError instead of a StopIteration now (like file and cString.String do).
2498 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2499 called before (like file and StringIO.StringIO do).

Martin v. Löwis3e865952006-01-24 15:51:21 +00002549 specifications, raises IOErrors when proxies for unsupported protocols
2550 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00002573 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2574 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2575 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2576 Ronald L. Rivest offered this advice for Python:
2577
2578 "The consensus of researchers in this area (at least as
2579 expressed at the NIST Hash Function Workshop 10/31/05),
2580 is that SHA-256 is a good choice for the time being, but
2581 that research should continue, and other alternatives may
2582 arise from this research. The larger SHA's also seem OK."

2637 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002638 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002639

2661 to W3C name (404 -> 'Not Found'). RFE #1216944.
2662
Georg Brandl9e43acf2005-07-04 17:16:07 +00002663- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2664 as this can cause problems with apps closing all file descriptors.

2677 Bug #1224621.
2678
Raymond Hettinger68c04532005-06-10 11:05:19 +00002679- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002680 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002681 the generate_tokens() function now accepts a callable argument that
2682 terminates by raising StopIteration.
2683
Georg Brandl9166e1a2005-06-04 09:20:03 +00002684- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2685
Georg Brandl268e61c2005-06-03 14:28:50 +00002686- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first

2688
Skip Montanaro174dd222005-05-14 20:54:16 +00002689- Patch #1120353: The xmlrpclib module provides better, more transparent,

2692 class at all.
2693
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002694- distutils.commands.upload was added to support uploading distribution
2695 files to PyPI.
2696
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002697- distutils.commands.register now encodes the data as UTF-8 before posting
2698 them to PyPI.
2699
Raymond Hettinger267b8682005-03-27 10:47:39 +00002700- decimal operator and comparison methods now return NotImplemented
2701 instead of raising a TypeError when interacting with other types. This
2702 allows other classes to implement __radd__ style methods and have them
2703 work as expected.
2704
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002705- Bug #1163325: Decimal infinities failed to hash. Attempting to
2706 hash a NaN raised an InvalidOperation instead of a TypeError.
2707
Tim Petersecc6e6a2005-07-10 22:30:55 +00002708- Patch #918101: Add tarfile open mode r|* for auto-detection of the

2742
Guido van Rossumd0641422005-02-03 15:01:24 +00002743- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2744 disables recursive traversal through instance attributes, which can
2745 be exploited in various ways.
2746
Tim Peterse3547fd2005-12-16 23:13:57 +00002747- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002748 flags on the HTTP listening socket.
2749
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002750- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2751 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2752
Fred Drakefbdeaad2006-07-29 16:56:15 +00002753- Patches #893642, #1039083: add allow_none, encoding arguments to
2754 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002755
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002756- Bug #1110478: Revert os.environ.update to do putenv again.
2757
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002758- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2759
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002760- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2761
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002762- Enhancements to the csv module:
2763
2764 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002765 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002766 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002767 + Dialect parameter parsing has been re-implemented to improve error
2768 reporting.
2769 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2770 dictates.
2771 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002772 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002773 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002774 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2775 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002776 + reader now allows \r characters to be quoted (previously it only allowed
2777 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002778 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002779 + Dialect classes passed to the module are no longer instantiated by
2780 the module before being parsed (the former validation scheme required
2781 this, but the mechanism was unreliable).
2782 + The dialect registry now contains instances of the internal
2783 C-coded dialect type, rather than references to python objects.
2784 + the internal c-coded dialect type is now immutable.
2785 + register_dialect now accepts the same keyword dialect specifications
2786 as the reader and writer, allowing the user to register dialects
2787 without first creating a dialect class.
2788 + a configurable limit to the size of parsed fields has been added -
2789 previously, an unmatched quote character could result in the entire
2790 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002791 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002792 the parser field size limit (returning the former limit). The initial
2793 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002794 + A line_num attribute has been added to the reader object, which tracks
2795 the number of lines read from the source iterator. This is not
2796 the same as the number of records returned, as records can span
2797 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002798 + reader and writer objects were not being registered with the cyclic-GC.
2799 This has been fixed.
2800
Brett Cannone6539c42005-01-08 02:43:53 +00002801- _DummyThread objects in the threading module now delete self.__block that is
2802 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2803 lock primitives tend to be limited in number and thus should not be wasted on
2804 a _DummyThread object. Fixes bug #1089632.
2805
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002806- The imghdr module now detects Exif files.
2807
Raymond Hettinger6065d322004-12-20 23:51:53 +00002808- StringIO.truncate() now correctly adjusts the size attribute.
2809 (Bug #951915).
2810
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002811- locale.py now uses an updated locale alias table (built using
2812 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2813 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002814 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002815
Raymond Hettinger3557f422004-12-07 12:02:02 +00002816- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2817
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002818- the pickle module no longer accepts the deprecated None option in the
2819 args tuple returned by __reduce__().
2820
Brett Cannon84667c02004-12-07 03:25:18 +00002821- optparse now optionally imports gettext. This allows its use in setup.py.
2822
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002823- the pickle module no longer uses the deprecated bin parameter.
2824
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002825- the shelve module no longer uses the deprecated binary parameter.
2826
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002827- the pstats module no longer uses the deprecated ignore() method.
2828
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002829- the filecmp module no longer uses the deprecated use_statcache argument.
2830
Raymond Hettinger664347b2004-12-04 21:21:53 +00002831- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2832 extended or overridden by subclasses. Formerly, the subclassed method would
2833 be ignored by the rest of the module. (Bug #1078905).
2834
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002835- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002836 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002837
Walter Dörwald36733692004-12-22 12:50:50 +00002838- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2839 once when a size argument is given. This prevents a buffer overflow in the
2840 tokenizer with very long source lines.
2841
Barry Warsaw538561e2006-01-01 21:48:54 +00002842- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2843 immediately after creating the object, without any intervening
2844 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002845
Skip Montanaro05885812005-01-16 20:48:27 +00002846- The reconvert.quote function can now emit triple-quoted strings. The
2847 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002848
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002849- ``UserString.MutableString`` now supports negative indices in
2850 ``__setitem__`` and ``__delitem__``
2851
Greg Ward40407942005-03-05 02:53:17 +00002852- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2853 correctly.
2854
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002855- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2856 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2857 character even if the user has passed a size parameter to get a proper
2858 line ending. Remove the special handling of a "\r\n" that has been split
2859 between two lines.
2860
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002861- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2862 about illegal code points. The codec now supports PEP 293 style error
2863 handlers.
2864
Walter Dörwald78a78b02005-09-01 12:04:29 +00002865- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002866 from the input stream, so that the output is a byte string in the correct
2867 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002868
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002869- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2870 considering it exactly like a '*'.
2871
Walter Dörwald007f8df2005-10-09 19:42:27 +00002872- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2873 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002874
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002875- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2876
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002877- Patch #1413711: Certain patterns of differences were making difflib
2878 touch the recursion limit.
2879
Walter Dörwald58917a62006-03-31 15:26:22 +00002880- Bug #947906: An object oriented interface has been added to the calendar
2881 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002882 called as a script (e.g. via ``python -mcalendar``). Localized month and
2883 weekday names can be ouput (even if an exotic encoding is used) using
2884 special classes that use unicode.

2887-----
2888
Neal Norwitz602d3392006-03-31 08:21:40 +00002889- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2890 by using -mieee gcc option.
2891

2893
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002894- Build support for Win64-AMD64 was added.
2895
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002896- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2897
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002898- Patch #881820: look for openpty and forkpty also in libbsd.
2899
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002900- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2901 The zlib module is now builtin on Windows.
2902
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002903- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2904
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002905- Bug #1189330: configure did not correctly determine the necessary
2906 value of LINKCC if python was built with GCC 4.0.
2907
Trent Mick8321b422005-07-26 02:29:21 +00002908- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2909 vulnerability in zlib 1.2.1 and 1.2.2.
2910
Brett Cannon08cd5982005-04-24 22:26:38 +00002911- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2912 flags that change binary compatibility. Changes were also made to
2913 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002914 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002915
Bob Ippolitoed233462005-03-29 13:47:59 +00002916- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2917 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2918 no longer exists). This configure patch makes things right.
2919
Martin v. Löwise2713be2005-03-08 15:03:08 +00002920- Bug #1158607: Build with --disable-unicode again.
2921
Brett Cannon46d96232005-02-16 00:07:19 +00002922- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2923 defined. Discovered as a result of not being able to build on OS X.
2924
Brett Cannon516592f2004-12-07 00:42:59 +00002925- setup.py now uses the directories specified in LDFLAGS using the -L option
2926 and in CPPFLAGS using the -I option for adding library and include
2927 directories, respectively, for compiling extension modules against. This has
2928 led to the core being compiled using the values in CPPFLAGS. It also removes
2929 the need for the special-casing of both DarwinPorts and Fink for darwin since
2930 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2931 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2932 Fink, ``-I/opt/local/include`` for DarwinPorts).
2933
Brett Cannon43802422005-02-10 20:48:03 +00002934- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2935 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2936 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2937 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002939C API
2940-----
2941
Tim Petersc9d78aa2006-03-26 23:27:58 +00002942- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2943 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2944 is obtained via the ``PyObject_`` family, it must be released via the
2945 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2946 always been officially true, but when Python's small-object allocator was
2947 introduced, an attempt was made to cater to a few extension modules
2948 discovered at the time that obtained memory via ``PyObject_New`` but
2949 released it via ``PyMem_DEL``. It's years later, and if such code still
2950 exists it will fail now (probably with segfaults, but calling wrong
2951 low-level memory management functions can yield many symptoms).
2952
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002953- Added a C API for set and frozenset objects.
2954
Raymond Hettinger66517482004-12-03 11:45:13 +00002955- Removed PyRange_New().
2956
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002957- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2958 mapping argument now. This string is used as a mapping table. Byte values
2959 greater than the length of the string and 0xFFFE are treated as undefined
2960 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002967
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002968- Patch #1276356: New resource "urlfetch" is implemented. This enables
2969 even impatient people to run tests that require remote files.
