Nick Coghlanbb0996c2006-09-03 01:20:46 +00007What's New in Python 2.6 alpha 1?
8=================================
Martin v. Löwis2eb8c4f2006-08-18 03:47:18 +00009
Neal Norwitz92422fb2006-08-18 03:57:54 +000010*Release date: XX-XXX-200X*
11
12Core and builtins
13-----------------
14
Neal Norwitz0ac60192007-05-27 04:08:54 +000015- Add new attribute names for function objects. All the func_* become
16 __*__ attributes. (Some already existed, e.g., __doc__ and __name__.)
17
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +000018- Add -3 option to the interpreter to warn about features that are
19 deprecated and will be changed/removed in Python 3.0.
20
Georg Brandl2134e752007-05-21 20:34:16 +000021- Patch #1686487: you can now pass any mapping after '**' in function
22 calls.
23
Collin Winter62903052007-05-18 23:11:24 +000024- except clauses may now be spelled either "except E, target:" or
25 "except E as target:". This is to provide forwards compatibility with
26 Python 3.0.
27
Brett Cannon229cee22007-05-05 01:34:02 +000028- Deprecate BaseException.message as per PEP 352.
29
Armin Rigo9790a272007-05-02 19:23:31 +000030- Bug #1303614: don't expose object's __dict__ when the dict is
31 inherited from a builtin base.
32
Vinay Sajip8549ce32007-05-06 17:53:37 +000033- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +000034 setting a plain string, ie don't expand to single letter identifiers.
35
Raymond Hettinger13936692007-04-11 18:40:58 +000036- Request #1191699: Slices can now be pickled.
37
Raymond Hettinger4db5fe92007-04-12 04:10:00 +000038- Request #1193128: str.translate() now allows a None argument for
39 translations that only remove characters without re-mapping the
40 remaining characters.
41
Georg Brandl5cb76c12007-03-21 09:00:39 +000042- Patch #1682205: a TypeError while unpacking an iterable is no longer
43 masked by a generic one with the message "unpack non-sequence".
44
Neal Norwitzaa754b72007-03-21 06:39:48 +000045- Remove unused file Python/fmod.c.
46
Guido van Rossum143b5642007-03-23 04:58:42 +000047- Bug #1683368: The object.__init__() and object.__new__() methods are
48 now stricter in rejecting excess arguments. The only time when
49 either allows excess arguments is when it is not overridden and the
50 other one is. For backwards compatibility, when both are
51 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +000052 warning later). Also, type.__init__() insists on the same signature
53 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +000054
Georg Brandl2b869942007-03-17 16:08:45 +000055- Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
56 to complex using its __complex__() method before falling back to the
57 __float__() method. Therefore, the functions in the cmath module now
58 can operate on objects that define a __complex__() method.
59
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +000060- Patch #1623563: allow __class__ assignment for classes with __slots__.
61 The old and the new class are still required to have the same slot names.
62
Collin Winter77c67bd2007-03-16 04:11:30 +000063- Patch #1642547: Fix an error/crash when encountering syntax errors in
64 complex if statements.
65
Žiga Seilnacht20f43d32007-03-15 11:44:55 +000066- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
67 is called with an object that is faking its type.
68
Žiga Seilnacht71436f02007-03-14 12:24:09 +000069- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
70 name.
71
Georg Brandl5240d742007-03-13 20:46:32 +000072- Patch #1444529: the builtin compile() now accepts keyword arguments.
73
Georg Brandl7b9c5552007-03-12 14:30:05 +000074- Bug #1678647: write a newline after printing an exception in any
75 case, even when converting the value to a string failed.
76
Georg Brandl871f1bc2007-03-12 13:17:36 +000077- The dir() function has been extended to call the __dir__() method on
78 its argument, if it exists. If not, it will work like before. This allows
79 customizing the output of dir() in the presence of a __getattr__().
80
Collin Winter276887b2007-03-12 16:11:39 +000081- Patch #922167: Python no longer segfaults when faced with infinitely
82 self-recursive reload() calls (as reported by bug #742342).
83
Žiga Seilnacht89032082007-03-11 15:54:54 +000084- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
85
Collin Wintere38051d2007-03-09 20:33:07 +000086- Patch #1491866: change the complex() constructor to allow parthensized
87 forms. This means complex(repr(x)) now works instead of raising a
88 ValueError.
89
Georg Brandlaa2321b2007-03-07 00:40:28 +000090- Patch #703779: unset __file__ in __main__ after running a file. This
91 makes the filenames the warning module prints much more sensible when
92 a PYTHONSTARTUP file is used.
93
Georg Brandl49aafc92007-03-07 00:34:46 +000094- Variant of patch #697613: don't exit the interpreter on a SystemExit
95 exception if the -i command line option or PYTHONINSPECT environment
96 variable is given, but break into the interactive interpreter just like
97 on other exceptions or normal program exit.
98
Georg Brandl00cd8182007-03-06 18:41:12 +000099- Patch #1638879: don't accept strings with embedded NUL bytes in long().
100
Georg Brandl098cd692007-03-06 12:17:50 +0000101- Bug #1674503: close the file opened by execfile() in an error condition.
102
Georg Brandl0fca97a2007-03-05 22:28:08 +0000103- Patch #1674228: when assigning a slice (old-style), check for the
104 sq_ass_slice instead of the sq_slice slot.
105
Neal Norwitz88516a62007-02-26 22:41:45 +0000106- When printing an unraisable error, don't print exceptions. before the name.
107 This duplicates the behavior whening normally printing exceptions.
108
Martin v. Löwisfd963262007-02-09 12:19:32 +0000109- Bug #1653736: Properly discard third argument to slot_nb_inplace_power.
110
Brett Cannon129bd522007-01-30 21:34:36 +0000111- PEP 352: Raising a string exception now triggers a TypeError. Attempting to
112 catch a string exception raises DeprecationWarning.
113
Brett Cannonf5bee302007-01-23 23:21:22 +0000114- Bug #1377858: Fix the segfaulting of the interpreter when an object created
115 a weakref on itself during a __del__ call for new-style classes (classic
116 classes still have the bug).
117
Martin v. Löwis6c5c5022007-01-23 21:11:47 +0000118- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
119 frame's thread state.
120
Thomas Wouters6ed19652007-01-23 13:50:49 +0000121- patch #1630975: Fix crash when replacing sys.stdout in sitecustomize.py
122
Martin v. Löwis4885e7d2007-01-19 06:42:22 +0000123- Bug #1637022: Prefix AST symbols with _Py_.
124
Neal Norwitz72cd02c2007-01-05 05:25:22 +0000125- Prevent seg fault on shutdown which could occur if an object
126 raised a warning.
127
Martin v. Löwis7b7c9d42007-01-04 21:06:12 +0000128- Bug #1566280: Explicitly invoke threading._shutdown from Py_Main,
129 to avoid relying on atexit.
130
Raymond Hettinger94547f72006-12-20 06:42:06 +0000131- Bug #1590891: random.randrange don't return correct value for big number
132
Georg Brandl283a1352006-11-19 08:48:30 +0000133- Patch #1586791: Better exception messages for some operations on strings,

148 again, no longer the posix error code.
149
Martin v. Löwisb5bc5372006-10-27 06:16:31 +0000150- Patch #1549049: Support long values in structmember, issue warnings
151 if the assigned value for structmember fields gets truncated.
152
Neal Norwitzcbeb6872006-10-14 21:33:38 +0000153- Update the peephole optimizer to remove more dead code (jumps after returns)
154 and inline unconditional jumps to returns.
155
Georg Brandl2c1375c2006-10-12 11:27:59 +0000156- Bug #1545497: when given an explicit base, int() did ignore NULs
157 embedded in the string to convert.
158
Georg Brandl846f73a2006-10-08 07:11:54 +0000159- Bug #1569998: break inside a try statement (outside a loop) is now
160 recognized and rejected.
161
Armin Rigo7ccbca92006-10-04 12:17:45 +0000162- list.pop(x) accepts any object x following the __index__ protocol.
163
164- Fix some leftovers from the conversion from int to Py_ssize_t
165 (relevant to strings and sequences of more than 2**31 items).
166
167- A number of places, including integer negation and absolute value,
168 were fixed to not rely on undefined behaviour of the C compiler
169 anymore.
Martin v. Löwis820d6ac2006-10-04 05:47:34 +0000170

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

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

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

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

Brett Cannon5e263512007-05-20 23:17:38 +0000910- Removed the macfs module. It had been deprecated since Python 2.5. This
911 lead to the deprecation of macostools.touched() as it relied solely on macfs
912 and was a no-op under OS X.

Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000923- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000924 compared equal or unequal to a string and a UnicodeDecodeError
925 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000926
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000927 Instead, the equal (==) and unequal (!=) comparison operators will
928 now issue a UnicodeWarning and interpret the two objects as
929 unequal. The UnicodeWarning can be filtered as desired using
930 the warning framework, e.g. silenced completely, turned into an
931 exception, logged, etc.
932
933 Note that compare operators other than equal and unequal will still
934 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000935
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000936- Fix segfault when doing string formatting on subclasses of long.
937
938- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
939 with new-style classes.
940
941- Fix bug related to __len__ functions returning negative values with
942 classic classes.
943
944- Patch #1538606, Fix __index__() clipping. There were some problems
945 discovered with the API and how integers that didn't fit into Py_ssize_t
946 were handled. This patch attempts to provide enough alternatives
947 to effectively use __index__.
948
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000949- Bug #1536021: __hash__ may now return long int; the final hash
950 value is obtained by invoking hash on the long int.
951
Thomas Hellerab1049c2006-08-08 17:37:00 +0000952- Bug #1536786: buffer comparison could emit a RuntimeWarning.
953
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000954- Bug #1535165: fixed a segfault in input() and raw_input() when
955 sys.stdin is closed.
956
Thomas Heller74d36f02006-08-04 18:17:40 +0000957- On Windows, the PyErr_Warn function is now exported from
958 the Python dll again.
959
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000960- Bug #1191458: tracing over for loops now produces a line event
961 on each iteration. Fixing this problem required changing the .pyc
962 magic number. This means that .pyc files generated before 2.5c1
963 will be regenerated.
964
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000965- Bug #1333982: string/number constants were inappropriately stored
966 in the byte code and co_consts even if they were not used, ie
967 immediately popped off the stack.
968
Georg Brandle9462c72006-08-04 18:03:37 +0000969- Fixed a reference-counting problem in property().

973-------
974
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +0000975- Fix a bug in the ``compiler`` package that caused invalid code to be
976 generated for generator expressions.
977
Marc-André Lemburg574cfea2006-08-16 16:11:01 +0000978- The distutils version has been changed to 2.5.0. The change to
979 keep it programmatically in sync with the Python version running
980 the code (introduced in 2.5b3) has been reverted. It will continue
981 to be maintained manually as static string literal.
982
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000983- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000984 and this cannot be converted to the required C type, an exception is
985 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +0000986 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +0000987
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000988- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +0000989 an exception.
990
Tim Petersc10c9d02006-09-05 02:18:09 +0000991- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000992 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +0000993 workarounds for clocks with low resolution, to stop the code yielding
994 duplicate UUIDs.
995
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +0000996- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
997 before raising SystemExit, allowing IDLE to honor quit() and exit().
998
Neal Norwitzbf8c1952006-08-15 04:14:57 +0000999- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1000
Georg Brandl7a1af772006-08-14 21:55:28 +00001001- Patch #1536071: trace.py should now find the full module name of a
1002 file correctly even on Windows.
1003
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001004- logging's atexit hook now runs even if the rest of the module has
1005 already been cleaned up.
1006
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001007- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001008
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001009- Bug #1531405, format_exception no longer raises an exception if
1010 str(exception) raised an exception.
1011
Neil Schemenauer06ded092006-08-04 16:20:30 +00001012- Fix a bug in the ``compiler`` package that caused invalid code to be
1013 generated for nested functions.

Georg Brandl3335a7a2006-08-14 21:42:55 +00001021- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
1022 raises the correct exceptions.
1023
Thomas Heller1ce433e2006-08-14 16:20:04 +00001024- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1025 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1026
Thomas Heller86720042006-08-14 11:17:48 +00001027- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1028 uses the _as_parameter_ attribute when objects are passed to foreign
1029 function calls. The ctypes version number was changed to 1.0.1.
1030
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001031- Bug #1530559, struct.pack raises TypeError where it used to convert.
1032 Passing float arguments to struct.pack when integers are expected
1033 now triggers a DeprecationWarning.

Martin v. Löwisa09fd6e2006-08-16 12:55:10 +00001059- Bug #1535502, build _hashlib on Windows, and use masm assembler
1060 code in OpenSSL.
1061
Thomas Hellerdb7b4432006-08-04 19:49:31 +00001062- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

1083Core and builtins
1084-----------------
1085
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001086- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001087 returned a long (see PEP 353).
1088
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001089- Bug #1515471: string.replace() accepts character buffers again.
1090
Neal Norwitz07aadb12006-07-30 06:55:48 +00001091- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1092 This provides the proper warning for struct.pack().
1093 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1094
Neal Norwitz0d62a062006-07-30 06:53:31 +00001095- Patch #1531113: Fix augmented assignment with yield expressions.
1096 Also fix a SystemError when trying to assign to yield expressions.
1097
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001098- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1099 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1100 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1101 excessive filesystem operations during imports.
1102
Tim Petersbc24eee2006-07-27 01:14:53 +00001103- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1104 operations on signed longs that are formally undefined by C.
1105 Unfortunately, at least one compiler now cares about that, so complicated
1106 the code to make that compiler happy again.
1107
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001108- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1109
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001110- Patch #1232023: Stop including current directory in search
1111 path on Windows.
1112
Neal Norwitze1fdb322006-07-21 05:32:28 +00001113- Fix some potential crashes found with failmalloc.
1114
Neal Norwitze7563102006-07-17 01:00:16 +00001115- Fix warnings reported by Klocwork's static analysis tool.
1116
Neal Norwitz84be93b2006-07-16 01:50:38 +00001117- Bug #1512814, Fix incorrect lineno's when code within a function
1118 had more than 255 blank lines.
1119
Georg Brandl9dceedb2006-07-12 15:31:17 +00001120- Patch #1521179: Python now accepts the standard options ``--help`` and
1121 ``--version`` as well as ``/?`` on Windows.
1122
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001123- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001124 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001125 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001126
Tim Peters112aad32006-07-19 00:03:19 +00001127- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001128 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001129 new ``sys._current_frames()`` returns a dictionary with one entry,
1130 mapping the faux "thread id" 0 to the current frame.
1131
Ronald Oussoren3075e162006-07-25 20:28:55 +00001132- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001133

1136-------
1137
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001138- Correction of patch #1455898: In the mbcs decoder, set final=False
1139 for stream decoder, but final=True for the decode function.
1140
Georg Brandl07fec3a2006-08-01 18:49:24 +00001141- os.urandom no longer masks unrelated exceptions like SystemExit or
1142 KeyboardInterrupt.
1143
Tim Peters4643c2f2006-08-10 22:45:34 +00001144- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001145 shutil.copytree on Windows
1146
Georg Brandle34ac7c2006-07-30 11:07:23 +00001147- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1148 refers to file descriptors, not file objects.
1149
Tim Petersc10c9d02006-09-05 02:18:09 +00001150- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001151 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001152 #1513611, and probably others.
1153
Georg Brandledd9b0d2006-07-29 09:33:26 +00001154- Bug #1441397: The compiler module now recognizes module and function
1155 docstrings correctly as it did in Python 2.4.
1156
Tim Peters6f681472006-07-27 23:44:37 +00001157- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1158 lost that tests are sorted by name before being run. This rarely
1159 matters for well-written tests, but can create baffling symptoms if
1160 side effects from one test to the next affect outcomes. ``DocTestFinder``
1161 has been changed to sort the list of tests it returns.
1162
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001163- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001164 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001165
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001166- Bug #978833: Really close underlying socket in _socketobject.close.
1167
Georg Brandl8c036cc2006-08-20 13:15:39 +00001168- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1169 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001170
Georg Brandlcf0c1722006-07-26 07:23:32 +00001171- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1172 to recursive calls and call it with the failing package name.
1173
Martin v. Löwis0b483032006-07-25 09:53:12 +00001174- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1175
Georg Brandlc13c34c2006-07-24 14:09:56 +00001176- Patch #1515343: Fix printing of deprecated string exceptions with a
1177 value in the traceback module.
1178
Greg Ward48fae7a2006-07-23 16:05:51 +00001179- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1180
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001181- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1182
Brett Cannoncaebe222006-07-18 04:41:36 +00001183- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1184 argument tuple. For arguments where zero is illegal, the value is forced to
1185 the minimum value that is correct. This is to support an undocumented but
1186 common way people used to fill in inconsequential information in the time
1187 tuple pre-2.4.
1188
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001189- Patch #1220874: Update the binhex module for Mach-O.
1190
Barry Warsawb110bad2006-07-21 14:51:07 +00001191- The email package has improved RFC 2231 support, specifically for
1192 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1193 (name*0=<blah>) parameter continuations. This may change the types of
1194 values returned from email.message.Message.get_param() and friends.
1195 Specifically in some cases where non-encoded continuations were used,
1196 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1197 will just return the string (since non-encoded continuations don't have
1198 charset and language parts).
1199
1200 Also, whereas % values were decoded in all parameter continuations, they are
1201 now only decoded in encoded parameter parts.
1202
Ronald Oussoren3075e162006-07-25 20:28:55 +00001203- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1204
1205- Bug #1517996: IDLE now longer shows the default Tk menu when a
1206 path browser, class browser or debugger is the frontmost window on MacOS X
1207
Barry Warsaw00decd72006-07-27 23:43:15 +00001208- Patch #1520294: Support for getset and member descriptors in types.py,
1209 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1210 of an object against these built-in types and more importantly, for getting
1211 their docstrings printed in the interactive interpreter's help() function.

1215-----------------
1216
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001217- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1218 a socket operation on a socket with a timeout, the exception will be
1219 caught correctly. Previously, the exception was not caught.
1220
Thomas Heller1393d6a2006-07-28 21:43:20 +00001221- Patch #1529514: The _ctypes extension is now compiled on more
1222 openbsd target platforms.
1223
Tim Peters9cab5932006-07-28 00:30:00 +00001224- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1225 a memory leak, affecting pickles and deep copies.
1226
Tim Petersbc24eee2006-07-27 01:14:53 +00001227- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1231
Thomas Hellerce049a02006-07-14 17:51:14 +00001232- Patch #1521817: Index range checking on ctypes arrays containing
1233 exactly one element enabled again. This allows iterating over these
1234 arrays, without the need to check the array size before.
1235
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001236- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001237 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001238 /dev/null in certain cases; this is now fixed.
1239
Thomas Heller47d7a062006-07-12 08:43:47 +00001240- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1241 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001242
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001243- Because of a misspelled preprocessor symbol, ctypes was always
1244 compiled without thread support; this is now fixed.
1245
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001246- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1247 methods now allow their database parameter to be None as the
1248 sleepycat API allows.
1249
Matt Flemingec926502006-07-28 11:27:27 +00001250- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1251 bluetooth API compared with Linux and FreeBSD.
1252
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001253Tests
1254-----
1255
1256- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1257 how long the test file should take to play. Now accepts taking 2.93 secs
1258 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1259
Georg Brandl4793aa32006-07-28 18:31:39 +00001260- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1261 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1262 run via ``regrtest.py``. Now they do.

Martin v. Löwis0907f4d2006-07-30 14:09:47 +00001264Build
1265-----
1266
1267- Bug #1439538: Drop usage of test -e in configure as it is not portable.
1268
Ronald Oussoren26cad082006-08-01 21:00:57 +00001269Mac
1270---
1271
1272- PythonLauncher now works correctly when the path to the script contains
1273 characters that are treated specially by the shell (such as quotes).
1274
1275- Bug #1527397: PythonLauncher now launches scripts with the working directory
1276 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001277 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001278 expect.

1287-----------------
1288
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001289- Bug #1441486: The literal representation of -(sys.maxint - 1)
1290 again evaluates to a int object, not a long.
1291
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001292- Bug #1501934: The scope of global variables that are locally assigned
1293 using augmented assignment is now correctly determined.
1294
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001295- Bug #927248: Recursive method-wrapper objects can now safely
1296 be released.
1297
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001298- Bug #1417699: Reject locale-specific decimal point in float()
1299 and atof().
1300
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001301- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1302 omit a default "error" argument for NULL pointer. This allows
1303 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001304
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001305- Bug #1519018: 'as' is now validated properly in import statements.
1306
Neal Norwitz28746ab2006-07-09 22:14:42 +00001307- On 64 bit systems, int literals that use less than 64 bits are
1308 now ints rather than longs.
1309
Neal Norwitzed657552006-07-10 00:04:44 +00001310- Bug #1512814, Fix incorrect lineno's when code at module scope
1311 started after line 256.
1312
Tim Peters32a83612006-07-10 21:08:24 +00001313- New function ``sys._current_frames()`` returns a dict mapping thread
1314 id to topmost thread stack frame. This is for expert use, and is
1315 especially useful for debugging application deadlocks. The functionality
1316 was previously available in Fazal Majid's ``threadframe`` extension
1317 module, but it wasn't possible to do this in a wholly threadsafe way from
1318 an extension.
1319

1335
Thomas Woutersadd19112006-07-05 11:03:49 +00001336- string.Template() now correctly handles tuple-values. Previously,
1337 multi-value tuples would raise an exception and single-value tuples would
1338 be treated as the value they contain, instead.
1339
Martin v. Löwisede77f52006-07-03 13:01:35 +00001340- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1342
Martin v. Löwis45482392006-07-03 12:28:58 +00001343- Bug #1267547: Put proper recursive setup.py call into the

1347 degrees and radians.
1348
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001349- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001350 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001351
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001352- Bug #1514703: Only setup canvas window in turtle when the canvas
1353 is created.
1354
Martin v. Löwis7596e832006-07-01 15:33:37 +00001355- Bug #1513223: .close() of a _socketobj now releases the underlying
1356 socket again, which then gets closed as it becomes unreferenced.

1361- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1362 sgmllib ('[' and ']' were not accepted).
1363
Georg Brandl1be63af2006-06-28 20:23:25 +00001364- Fix a bug in the turtle module's end_fill function.
1365
Brett Cannon53ab5b72006-06-22 16:49:14 +00001366- Bug #1510580: The 'warnings' module improperly required that a Warning
1367 category be either a types.ClassType and a subclass of Warning. The proper
1368 check is just that it is a subclass with Warning as the documentation states.
1369
Georg Brandlad29e632006-06-21 17:45:17 +00001370- The compiler module now correctly compiles the new try-except-finally
1371 statement (bug #1509132).
1372
Neal Norwitz60373cd2006-06-22 06:30:50 +00001373- The wsgiref package is now installed properly on Unix.
1374
Vinay Sajip28e57612006-07-01 10:45:20 +00001375- A bug was fixed in logging.config.fileConfig() which caused a crash on
1376 shutdown when fileConfig() was called multiple times.
1377
Gerhard Häring762fbd32006-07-02 17:48:30 +00001378- The sqlite3 module did cut off data from the SQLite database at the first
1379 null character before sending it to a custom converter. This has been fixed
1380 now.
1381
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001382Extension Modules
1383-----------------
1384
Tim Peters112aad32006-07-19 00:03:19 +00001385- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1386 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1387 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001388
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001389- Assigning None to pointer type fields in ctypes structures possible
1390 overwrote the wrong fields, this is fixed now.
1391
1392- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1393 on non-Windows platforms.
1394
1395- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1396 integer or long, without range checking.
1397
1398- Patch #1517790: It is now possible to use custom objects in the ctypes
1399 foreign function argtypes sequence as long as they provide a from_param
1400 method, no longer is it required that the object is a ctypes type.
1401
1402- The '_ctypes' extension module now works when Python is configured
1403 with the --without-threads option.
1404
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001405- Bug #1513646: os.access on Windows now correctly determines write

1420
Tim Peters32a83612006-07-10 21:08:24 +00001421- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001422 Previously, the slight difference could cause compilation errors of the
1423 'zlib' module on systems with more than one version of zlib.
1424
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001425- The MSI compileall step was fixed to also support a TARGETDIR

1444 documentation for the warnings module.
1445
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001446- Patch #1509163: MS Toolkit Compiler no longer available.

1462
Brett Cannonea3912b2006-06-13 21:46:41 +00001463- Bug #992017: A classic class that defined a __coerce__() method that returned
1464 its arguments swapped would infinitely recurse and segfault the interpreter.
1465
Neal Norwitz909eb122006-06-12 02:13:21 +00001466- Fix the socket tests so they can be run concurrently.

Neal Norwitzb9845e72006-06-12 02:11:18 +00001470
Brett Cannon22565aa2006-06-09 22:31:23 +00001471- Bug #532646: object.__call__() will continue looking for the __call__
1472 attribute on objects until one without one is found. This leads to recursion
1473 when you take a class and set its __call__ attribute to an instance of the
1474 class. Originally fixed for classic classes, but this fix is for new-style.
1475 Removes the infinite_rec_3 crasher.
1476
Georg Brandl24250812006-06-09 18:45:48 +00001477- The string and unicode methods startswith() and endswith() now accept
1478 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1479
Brett Cannonde3b0522006-06-08 17:00:45 +00001480- Buffer objects, at the C level, never used the char buffer
1481 implementation even when the char buffer for the wrapped object was
1482 explicitly requested (originally returned the read or write buffer).
1483 Now a TypeError is raised if the char buffer is not present but is
1484 requested.
1485
Georg Brandlddbaa662006-06-04 21:56:52 +00001486- Patch #1346214: Statements like "if 0: suite" are now again optimized
1487 away like they were in Python 2.4.
1488
Georg Brandlb7c8f542006-05-27 12:30:25 +00001489- Builtin exceptions are now full-blown new-style classes instead of
1490 instances pretending to be classes, which speeds up exception handling
1491 by about 80% in comparison to 2.5a2.
1492
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001493- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1494 Unicode 4.1.
1495
Georg Brandlf4ef1162006-05-26 18:03:31 +00001496- Patch #921466: sys.path_importer_cache is now used to cache valid and
1497 invalid file paths for the built-in import machinery which leads to
1498 fewer open calls on startup.
1499
Tim Peters696cf432006-05-24 21:10:40 +00001500- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1501 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1502 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1503 the number of input digits (it was and remains linear-time for bases
1504 2, 4, 8, 16 and 32).
1505
Tim Petersb713ec22006-05-23 18:45:30 +00001506- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1507 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1508 an integer close to ``sys.maxint``. This was repaired by patch
1509 #1335972, which also gives a nice speedup.
1510
Richard Jonescebbefc2006-05-23 18:28:17 +00001511- Patch #1337051: reduced size of frame objects.
1512
1513- PyErr_NewException now accepts a tuple of base classes as its
1514 "base" parameter.
1515
Richard Jones7c88dcc2006-05-23 10:37:38 +00001516- Patch #876206: function call speedup by retaining allocated frame
1517 objects.
1518
Georg Brandl7b90e162006-05-18 07:01:27 +00001519- Bug #1462152: file() now checks more thoroughly for invalid mode
1520 strings and removes a possible "U" before passing the mode to the
1521 C library function.
1522
Neal Norwitz1004a532006-05-15 07:17:23 +00001523- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1524
Neal Norwitz373f0a72006-05-15 07:04:36 +00001525- Bug #1487966: Fix SystemError with conditional expression in assignment
1526
Martin v. Löwis879768d2006-05-11 13:28:43 +00001527- WindowsError now has two error code attributes: errno, which carries
1528 the error values from errno.h, and winerror, which carries the error
1529 values from winerror.h. Previous versions put the winerror.h values
1530 (from GetLastError()) into the errno attribute.
1531
Martin v. Löwis77736712006-05-04 05:51:03 +00001532- Patch #1475845: Raise IndentationError for unexpected indent.
1533
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001534- Patch #1479181: split open() and file() from being aliases for each other.
1535
Tim Peters44bd9862006-06-01 13:49:23 +00001536- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1537 methods were always silently ignored by dictionaries when comparing keys.
1538 They are now passed through (except when using the C API function
1539 ``PyDict_GetItem()``, whose semantics did not change).
1540
1541- Bug #1456209: In some obscure cases it was possible for a class with a
1542 custom ``__eq__()`` method to confuse dict internals when class instances
1543 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1544 No, you don't have any code that did this ;-)

1547-----------------
1548
Trent Mick960a3f82006-06-28 20:30:41 +00001549- Bug #1295808: expat symbols should be namespaced in pyexpat
1550
1551- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1552
Brett Cannon6ee7d012006-06-08 16:23:04 +00001553- Change binascii.hexlify to accept a read-only buffer instead of only a char
1554 buffer and actually follow its documentation.
1555
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001556- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1557
Nick Coghlanc649ec52006-05-29 12:43:05 +00001558- Patch #1478788 (modified version): The functional extension module has
1559 been renamed to _functools and a functools Python wrapper module added.
1560 This provides a home for additional function related utilities that are
1561 not specifically about functional programming. See PEP 309.
1562
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001563- Patch #1493701: performance enhancements for struct module.
1564
Georg Brandl378d5922006-05-17 14:26:50 +00001565- Patch #1490224: time.altzone is now set correctly on Cygwin.
1566
Georg Brandl8d3342b2006-05-16 07:38:27 +00001567- Patch #1435422: zlib's compress and decompress objects now have a
1568 copy() method.
1569
Andrew MacIntyre92913322006-06-13 15:04:24 +00001570- Patch #1454481: thread stack size is now tunable at runtime for thread
1571 enabled builds on Windows and systems with Posix threads support.
1572
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001573- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1574 (up to the system limit of 32K characters).
1575
1576- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1577 As a result, these functions now raise WindowsError instead of OSError.
1578
Tim Peters7a822da2006-05-25 21:50:17 +00001579- ``time.clock()`` on Win64 should use the high-performance Windows
1580 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1581 Windows platforms).
1582
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001583- Calling Tk_Init twice is refused if the first call failed as that
1584 may deadlock.
1585
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001586- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1587 accept it without potentially using an uninitialized pointer.
1588
1589- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1590 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1591 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001592
Gregory P. Smith372b5832006-06-05 18:48:21 +00001593- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001594 [pybsddb project SF patch number 1466734]
1595
Gregory P. Smith372b5832006-06-05 18:48:21 +00001596- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1597 parameter is supplied. [SF pybsddb bug #1477863]
1598
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001599- bsddb: the __len__ method of a DB object has been fixed to return correct
1600 results. It could previously incorrectly return 0 in some cases.
1601 Fixes SF bug 1493322 (pybsddb bug 1184012).
1602
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001603- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1604 aborts the db transaction safely when a modifier callback fails.
1605 Fixes SF python patch/bug #1408584.
1606
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001607- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001608 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001609 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1610 database calls that would previously deadlock. [SF python bug #775414]
1611
Vinay Sajip28e57612006-07-01 10:45:20 +00001612- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001613
Walter Dörwald4994d952006-06-19 08:07:50 +00001614- Patch #1506645: add Python wrappers for the curses functions
1615 is_term_resized, resize_term and resizeterm.

1619
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001620- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1621 functions.
1622
Martin v. Löwis3798da02006-06-17 18:44:27 +00001623- Patch #812986: Update turtle output even if not tracing.
1624
Vinay Sajip28e57612006-07-01 10:45:20 +00001625- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001626 Tkinter.BaseWidget.
1627
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001628- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1629
Martin v. Löwis337487e2006-06-17 09:15:14 +00001630- Patch #763580: Add name and value arguments to Tkinter variable
1631 classes.
1632
Georg Brandl83cc0d02006-06-14 08:50:03 +00001633- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1634 mime.types file for determining MIME types.
1635
Georg Brandl2605ca82006-06-14 06:08:31 +00001636- Bug #1339007: Shelf objects now don't raise an exception in their
1637 __del__ method when initialization failed.
1638
Martin v. Löwisd8251432006-06-14 05:21:04 +00001639- Patch #1455898: The MBCS codec now supports the incremental mode for
1640 double-byte encodings.
1641
Tim Peters43898b42006-06-14 04:09:25 +00001642- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1643 guarantee that adjacent triples in the return list always describe
1644 non-adjacent blocks. Previously, a pair of matching blocks could end
1645 up being described by multiple adjacent triples that formed a partition
1646 of the matching pair.
1647
Greg Ward0e0c9f42006-06-11 16:24:11 +00001648- Bug #1498146: fix optparse to handle Unicode strings in option help,
1649 description, and epilog.
1650
Greg Wardd1c797e2006-06-11 14:42:41 +00001651- Bug #1366250: minor optparse documentation error.
1652
Greg Ward7f547402006-06-11 00:40:49 +00001653- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1654 clarify docs.
1655
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001656- The wsgiref package has been added to the standard library.
1657
Nick Coghlan676725d2006-06-08 13:54:49 +00001658- The functions update_wrapper() and wraps() have been added to the functools
1659 module. These make it easier to copy relevant metadata from the original
1660 function when writing wrapper functions.
1661
Tim Petersd6a9eef2006-06-05 01:48:21 +00001662- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1663 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001664
Martin v. Löwis3f767792006-06-04 19:36:28 +00001665- Patch #1359618: Speed up charmap encoder by using a trie structure
1666 for lookup.
1667
Tim Petersd609b1a2006-06-02 23:22:51 +00001668- The functions in the ``pprint`` module now sort dictionaries by key
1669 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1670 if and only if its display required more than one line, although that
1671 wasn't documented. The new behavior increases predictability; e.g.,
1672 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1673
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001674- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1675 (thanks for J. J. Lee).
1676
Georg Brandl2b330372006-05-28 20:23:12 +00001677- Patch #1496206: improve urllib2 handling of passwords with respect to
1678 default HTTP and HTTPS ports.
1679
George Yoshidaf3c65de2006-05-28 16:39:09 +00001680- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1681
Bob Ippolito7298f272006-05-23 18:43:47 +00001682- Patch #1281707: speed up gzip.readline.
1683
Georg Brandlb89316f2006-05-17 15:51:16 +00001684- Patch #1180296: Two new functions were added to the locale module:
1685 format_string() to get the effect of "format % items" but locale-aware,
1686 and currency() to format a monetary number with currency sign.
1687
Georg Brandle3a25832006-05-17 14:56:04 +00001688- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1689 and several features added, such as speed and geometry control.
1690
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001691- Patch #1488881: add support for external file objects in bz2 compressed
1692 tarfiles.
1693
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001694- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1695 stdout arguments, making it possible to redirect input and output
1696 for remote debugging.
1697
1698- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1699 a couple of issues, notably handling of long file names using the
1700 GNU LONGNAME extension.
1701
1702- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1703 new flag when ``name`` is already the name of an option flag.
1704
1705- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1706 package.
1707
1708- Patch #1472854: make the rlcompleter.Completer class usable on non-
1709 UNIX platforms.
1710
1711- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1712
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001713- Bug #1472827: correctly escape newlines and tabs in attribute values in
1714 the saxutils.XMLGenerator class.

1746
1747*Release date: 27-APR-2006*

1749Core and builtins
1750-----------------
1751
Thomas Heller1b046642006-04-18 18:51:06 +00001752- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1753 by converting these apis from macros into exported functions again:
1754
1755 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1756 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1757 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne

1759 PyRun_String Py_CompileString
1760
Martin v. Löwis45294a92006-04-18 06:24:08 +00001761- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1762
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001763- All uses of PyStructSequence_InitType have been changed to initialize
1764 the type objects only once, even if the interpreter is initialized
1765 multiple times.
1766
Neal Norwitz61546162006-04-14 05:20:28 +00001767- Bug #1454485, array.array('u') could crash the interpreter. This was
1768 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1769 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1770
1771- Py_UNICODE is unsigned. It was always documented as unsigned, but
1772 due to a bug had a signed value in previous versions.

Tim Peters3a5e8b12006-04-11 01:44:07 +00001774- Patch #837242: ``id()`` of any Python object always gives a positive
1775 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1776 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001777 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001778 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001779
Tim Peters3a5e8b12006-04-11 01:44:07 +00001780 def __hash__(self):
1781 return id(self) # WRONG
1782
1783 because a hash result must be a (short) Python int but it was always
1784 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001785 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001786 was always usable as a hash value before this patch. That's no longer
1787 necessarily so.
1788
1789- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001790 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001791 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001792 #1454844)
1793
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001794- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1795 involving generators that have paused outside of any ``try`` or ``with``
1796 blocks. (In 2.5a1, a paused generator that was part of a reference
1797 cycle could not be garbage collected, regardless of whether it was
1798 paused in a ``try`` or ``with`` block.)

1812 the cachesize parameter.
1813
1814- Bug #1149413: bsddb.*open() no longer raises an exception when using
1815 a temporary db (file=None) with the 'n' flag to truncate on open.
1816
1817- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1818 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001819
Armin Rigoa9017c32006-04-19 11:50:27 +00001820- Patch #1062014: AF_UNIX sockets under Linux have a special

1825
Peter Astrand7d1d4362006-07-14 14:04:45 +00001826- Bug #1223937: subprocess.CalledProcessError reports the exit status
1827 of the process using the returncode attribute, instead of
1828 abusing errno.
1829
Tim Peters711bf302006-04-25 03:31:36 +00001830- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1831 a doctest to be skipped (the code is not run, and the expected output
1832 or exception is ignored).
1833
Nick Coghlanda2268f2006-04-24 04:37:15 +00001834- Fixed contextlib.nested to cope with exceptions being raised and
1835 caught inside exit handlers.
1836
Greg Wardab05edc2006-04-23 03:47:58 +00001837- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1838 hex, octal, or binary; add ``append_const`` action; keep going if
1839 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1840 added ``epilog`` for better help generation).
1841
Tim Peters21fbd572006-04-21 21:18:10 +00001842- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1843 called from a thread spawned as a side effect of importing a module.
1844
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001845- The pydoc module now supports documenting packages contained in
1846 .zip or .egg files.
1847
1848- The pkgutil module now has several new utility functions, such
1849 as ``walk_packages()`` to support working with packages that are either
1850 in the filesystem or zip files.
1851
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001852- The mailbox module can now modify and delete messages from
1853 mailboxes, in addition to simply reading them. Thanks to Gregory
1854 K. Johnson for writing the code, and to the 2005 Google Summer of
1855 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001856

1879
Skip Montanaro262fb922006-04-21 02:31:07 +00001880- The pstats.Stats class accepts an optional stream keyword argument to
1881 direct output to an alternate file-like object.
1882
Anthony Baxter51bcb682006-04-05 14:51:42 +00001883Build
1884-----
1885
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001886- The Makefile now has a reindent target, which runs reindent.py on
1887 the library.
1888
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001889- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001892
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001893- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1894 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001895 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001896 CXX from --with-cxx-main, see description in README.
1897
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001898- Patch #1429775: Link extension modules with the shared libpython.
1899
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001900- Fixed a libffi build problem on MIPS systems.
1901
Tim Peters8931ff12006-05-13 23:28:20 +00001902- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1903 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1904 and "%zu" for unsigned integers of type ``size_t``.
1905
Anthony Baxter51bcb682006-04-05 14:51:42 +00001906Tests
1907-----
1908
Nick Coghlanda2268f2006-04-24 04:37:15 +00001909- test_contextlib now checks contextlib.nested can cope with exceptions
1910 being raised and caught inside exit handlers.
1911
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001912- test_cmd_line now checks operation of the -m and -c command switches
1913
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001914- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1915 it separately and by hand. It also wasn't cleaning up its changes to
1916 the current Decimal context.
1917
Thomas Woutersabd08882006-04-26 15:53:30 +00001918- regrtest.py now has a -M option to run tests that test the new limits of
1919 containers, on 64-bit architectures. Running these tests is only sensible
1920 on 64-bit machines with more than two gigabytes of memory. The argument
1921 passed is the maximum amount of memory for the tests to use.

1930-------------
1931
Tim Petersb06d28c2006-05-12 01:57:59 +00001932- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1933
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001934- PEP 343: Added Context Types section to the library reference
1935 and attempted to bring other PEP 343 related documentation into
1936 line with the implementation and/or python-dev discussions.
1937
Tim Peters8dc73d22006-04-24 02:03:16 +00001938- Bug #1337990: clarified that ``doctest`` does not support examples
1939 requiring both expected output and an exception.

Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001946
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001947Core and builtins
1948-----------------
1949
Nick Coghlan43832302006-04-23 17:04:07 +00001950- PEP 338: -m command line switch now delegates to runpy.run_module
1951 allowing it to support modules in packages and zipfiles
1952
Martin v. Löwisc661b882006-04-20 04:54:23 +00001953- On Windows, .DLL is not an accepted file name extension for
1954 extension modules anymore; extensions are only found if they
1955 end in .PYD.
1956
Martin v. Löwisea62d252006-04-03 10:56:49 +00001957- Bug #1421664: sys.stderr.encoding is now set to the same value as
1958 sys.stdout.encoding.
1959
Neal Norwitz92e212f2006-04-03 04:48:37 +00001960- __import__ accepts keyword arguments.
1961
Georg Brandlccadf842006-03-31 18:54:53 +00001962- Patch #1460496: round() now accepts keyword arguments.
1963
Anthony Baxter262c00a2006-03-30 10:53:17 +00001964- Fixed bug #1459029 - unicode reprs were double-escaped.
1965
Hye-Shik Changd478f342006-03-23 12:32:36 +00001966- Patch #1396919: The system scope threads are reenabled on FreeBSD
1967 5.4 and later versions.
1968
Neal Norwitze98ccf62006-03-23 05:39:47 +00001969- Bug #1115379: Compiling a Unicode string with an encoding declaration
1970 now gives a SyntaxError.
1971
Georg Brandlabd1ff82006-03-18 07:59:59 +00001972- Previously, Python code had no easy way to access the contents of a
1973 cell object. Now, a ``cell_contents`` attribute has been added
1974 (closes patch #1170323).
1975
Tim Peterscf79aac2006-03-16 01:14:46 +00001976- Patch #1123430: Python's small-object allocator now returns an arena to
1977 the system ``free()`` when all memory within an arena becomes unused
1978 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
1979 freed. Some applications will see a drop in virtual memory size now,
1980 especially long-running applications that, from time to time, temporarily
1981 use a large number of small objects. Note that when Python returns an
1982 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001983 platform C library will in turn return that memory to the operating system.
1984 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00001985 appears to be effective at least on Microsoft C and gcc-based systems.
1986 Thanks to Evan Jones for hard work and patience.
1987
Georg Brandl533ff6f2006-03-08 18:09:27 +00001988- Patch #1434038: property() now uses the getter's docstring if there is
1989 no "doc" argument given. This makes it possible to legitimately use
1990 property() as a decorator to produce a read-only property.
1991
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00001992- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
1993 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
1994 of requiring an int or long in slicing and a few other contexts, enabling
1995 other objects (e.g. Numeric Python's integers) to be used as slice indices.
1996
Neal Norwitz995acdf2006-03-07 05:01:00 +00001997- Fixed various bugs reported by Coverity's Prevent tool.
1998
Brett Cannonbf364092006-03-01 04:25:17 +00001999- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2000 new exception base class, BaseException, which has a new message attribute.
2001 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2002 Raising a string exception now raises a DeprecationWarning.
2003
Thomas Woutersfb609f42006-02-28 16:37:25 +00002004- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2005 explicitly relative, using 'from .module import name' to mean 'from the same
2006 package as this module is in. Imports without dots still default to the
2007 old relative-then-absolute, unless 'from __future__ import
2008 absolute_import' is used.
2009
Brett Cannona7446e32006-02-27 23:39:10 +00002010- Properly check if 'warnings' raises an exception (usually when a filter set
2011 to "error" is triggered) when raising a warning for raising string
2012 exceptions.
2013
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002014- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002015 The name was removed from Include/code.h.
2016
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002017- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002018
Guido van Rossum1968ad32006-02-25 22:38:04 +00002019- Patch 1433928:
2020 - The copy module now "copies" function objects (as atomic objects).
2021 - dict.__getitem__ now looks for a __missing__ hook before raising
2022 KeyError.
2023
Tim Peters84ef21c2006-02-28 20:39:06 +00002024- PEP 343: with statement implemented. Needs ``from __future__ import
2025 with_statement``. Use of 'with' as a variable will generate a warning.
2026 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002027 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002028 The following objects have __context__ methods:
2029 - The built-in file type.
2030 - The thread.LockType type.
2031 - The following types defined by the threading module:
2032 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2033 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002034
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002035- Fix the encodings package codec search function to only search
2036 inside its own package. Fixes problem reported in patch #1433198.
2037
2038 Note: Codec packages should implement and register their own
2039 codec search function. PEP 100 has the details.
2040
Tim Peters9ea89d22006-06-04 03:26:02 +00002041- PEP 353: Using ``Py_ssize_t`` as the index type.
2042
2043- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2044 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2045 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2046 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2047 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002048
Neal Norwitzfc76d632006-01-10 06:03:13 +00002049- Patch #1400181, fix unicode string formatting to not use the locale.
2050 This is how string objects work. u'%f' could use , instead of .
2051 for the decimal point. Now both strings and unicode always use periods.
2052
Neal Norwitz671b9e32006-01-09 07:07:12 +00002053- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2054 configure would break checking curses.h.
2055
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002056- Bug #959576: The pwd module is now builtin. This allows Python to be
2057 built on UNIX platforms without $HOME set.
2058
Neal Norwitzc10978f2005-12-19 06:07:16 +00002059- Bug #1072182, fix some potential problems if characters are signed.
2060
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002061- Bug #889500, fix line number on SyntaxWarning for global declarations.
2062
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002063- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2064
Neal Norwitze7214a12005-12-18 05:03:17 +00002065- Support for converting hex strings to floats no longer works.
2066 This was not portable. float('0x3') now raises a ValueError.
2067
Barry Warsaw2a38a862005-12-18 01:27:35 +00002068- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002069 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002070 is now displayed in interactive prompt banner.
2071
Georg Brandlfa166682005-12-17 21:45:17 +00002072- Implementation of PEP 341 - Unification of try/except and try/finally.
2073 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002074 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002075
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002076- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2077 now encodes backslash correctly.
2078
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002079- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2080
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002081- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002082 and long longs.
2083
Neal Norwitz67715f02005-11-09 06:59:35 +00002084- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002085 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002086 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002087
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002088- Replaced most Unicode charmap codecs with new ones using the
2089 new Unicode translate string feature in the builtin charmap
2090 codec; the codecs were created from the mapping tables available
2091 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2092 encodings now include a mapping for the Apple logo)
2093
Tim Peterse3547fd2005-12-16 23:13:57 +00002094- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002095
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002096- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002097
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002098- A new AST parser implementation was completed. The abstract
2099 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002100 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002101
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002102- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002103 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2104
Neal Norwitz708e51a2005-10-03 04:48:15 +00002105- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2106
Neal Norwitz11bd1192005-10-03 00:54:56 +00002107- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2108 Provide a warning when a directory is passed on the command line.
2109
Neal Norwitz40d37812005-10-02 01:48:49 +00002110- Fix segfault with invalid coding.
2111
2112- SF bug #772896: unknown encoding results in MemoryError.
2113
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002114- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002115 supported a __len__() method which evaluated to False when the iterator
2116 was empty.
2117
Guido van Rossum630db602005-09-20 18:49:54 +00002118- On 64-bit platforms, when __len__() returns a value that cannot be
2119 represented as a C int, raise OverflowError.
2120
Skip Montanarof8948ca2005-09-19 03:54:46 +00002121- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002122 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002123
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002124- SF bug #893549: parsing keyword arguments was broken with a few format
2125 codes.
2126
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002127- Changes donated by Elemental Security to make it work on AIX 5.3
2128 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2129 bug #105470: test_pwd fails on 64bit system (Opteron).
2130
Guido van Rossum539c6622005-09-14 17:49:54 +00002131- Changes donated by Elemental Security to make it work on HP-UX 11 on
2132 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2133
Georg Brandl4550b8d2005-08-26 06:43:52 +00002134- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002135 (fixes bug #1119418).
2136
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002137- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2138
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002139- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2140 exceptions that cause a function to exit.
2141
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002142- The implementation of set() and frozenset() was revised to use its
2143 own internal data structure. Memory consumption is reduced by 1/3
2144 and there are modest speed-ups as well. The API is unchanged.
2145
Tim Petersde7990b2005-07-17 23:45:23 +00002146- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2147
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002148- SF bug #1229429: PyObject_CallMethod failed to decrement some
2149 reference counts in some error exit cases.
2150
Tim Petersecc6e6a2005-07-10 22:30:55 +00002151- SF bug #1185883: Python's small-object memory allocator took over
2152 a block managed by the platform C library whenever a realloc specified
2153 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002154 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002155 portable way to copy data from the C-managed block into Python's
2156 small-object space without risking a memory fault. Python's small-object
2157 realloc now leaves such blocks under the control of the platform C
2158 realloc.
2159
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002160- SF bug #1232517: An overflow error was not detected properly when
2161 attempting to convert a large float to an int in os.utime().
2162
Raymond Hettinger3296e692005-06-29 23:29:56 +00002163- SF bug #1224347: hex longs now print with lowercase letters just
2164 like their int counterparts.
2165
Michael W. Hudson188d4362005-06-20 16:52:57 +00002166- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2167 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2168 interpreter states; back out that fix and do a better job (see
2169 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2170 for a longer write-up of the problem).
2171
Michael W. Hudsondf888462005-06-03 14:41:55 +00002172- SF patch #1180995: marshal now uses a binary format by default when
2173 serializing floats.
2174
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002175- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2176 the routines that promise to produce IEEE 754 binary representations
2177 of floats now simply copy bytes around.
2178
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002179- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2180 278.
2181
Brett Cannonc3647ac2005-04-26 03:45:26 +00002182- patch #1109424: int, long, float, complex, and unicode now check for the
2183 proper magic slot for type conversions when subclassed. Previously the
2184 magic slot was ignored during conversion. Semantics now match the way
2185 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002186 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002187 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002188 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002189
Barry Warsawc8d907c2005-04-19 23:43:40 +00002190- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2191 NULL, now raise an AttributeError when attempting to set or delete the
2192 attribute. Previously a TypeError was raised, but this was inconsistent
2193 with the equivalent pure-Python implementation.
2194
Michael W. Hudson774479c2005-04-18 08:46:17 +00002195- It is now safe to call PyGILState_Release() before
2196 PyEval_InitThreads() (note that if there is reason to believe there
2197 are multiple threads around you still must call PyEval_InitThreads()
2198 before using the Python API; this fix is for extension modules that
2199 have no way of knowing if Python is multi-threaded yet).
2200
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002201- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2202 disabled caused a crash.
2203
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002204- Bug #1165306: instancemethod_new allowed the creation of a method
2205 with im_class == im_self == NULL, which caused a crash when called.
2206
Tim Petersecc6e6a2005-07-10 22:30:55 +00002207- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002208 fixes the crash seen in bug #1165761
2209
Raymond Hettinger96229b12005-03-11 06:49:40 +00002210- Added two new builtins, any() and all().
2211
Brett Cannon409d8f22005-03-05 06:47:57 +00002212- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002213 (e.g., ``class C(): pass`` is no longer a syntax error).
2214 Patch #1176012 added support to the 'parser' module and 'compiler' package
2215 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002216
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002217- Patch #1115086: Support PY_LONGLONG in structmember.
2218
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002219- Bug #1155938: new style classes did not check that __init__() was
2220 returning None.
2221
Tim Petersecc6e6a2005-07-10 22:30:55 +00002222- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002223 ('\') with a specific error message.
2224
Martin v. Löwisff232d72005-03-03 09:24:38 +00002225- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2226
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002227- Bug #1124295: the __name__ attribute of file objects was
2228 inadvertently made inaccessible in restricted mode.
2229
Tim Petersecc6e6a2005-07-10 22:30:55 +00002230- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002231 an ferror() call.
2232
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002233- min() and max() now support key= arguments with the same meaning as in
2234 list.sort().
2235
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002236- The peephole optimizer now performs simple constant folding in expressions:
2237 (2+3) --> (5).
2238
Raymond Hettingera422c342005-01-11 03:03:27 +00002239- set and frozenset objects can now be marshalled. SF #1098985.
2240
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002241- Bug #1077106: Poor argument checking could cause memory corruption
2242 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002243
Jeremy Hyltonab630502005-02-04 18:44:06 +00002244- The parser did not complain about future statements in illegal
2245 positions. It once again reports a syntax error if a future
2246 statement occurs after anything other than a doc string.
2247
Neil Schemenauercf52c072005-08-12 17:34:58 +00002248- Change the %s format specifier for str objects so that it returns a
2249 unicode instance if the argument is not an instance of basestring and
2250 calling __str__ on the argument returns a unicode instance.
2251
Tim Petersf4e69282006-02-27 17:15:31 +00002252- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2253 current thread state when the auto-GIL-state machinery knows about
2254 it (since the thread state is being deleted, continuing to remember it
2255 can't help, but can hurt if another thread happens to get created with
2256 the same thread id).
2257
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002258Extension Modules
2259-----------------
2260
Georg Brandl43f08a82006-03-31 18:01:16 +00002261- Patch #1380952: fix SSL objects timing out on consecutive read()s

2264
Anthony Baxterfa869072006-03-20 05:21:58 +00002265- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
2266 In addition, the existing ulaw code was updated.
2267
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002268- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00002269 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002270
Neal Norwitz10be10c2006-03-16 06:50:13 +00002271- Everything under lib-old was removed. This includes the following modules:
2272 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00002273 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00002274 util, whatsound, whrandom, zmod
2275
2276- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2277
2278- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002279 is deprecated. The undocumented re.engine variable no longer exists.
2280
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002281- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2282 SS2 (single-shift 2) escape sequences correctly.
2283
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002284- The unicodedata module was updated to the 4.1 version of the Unicode
2285 database. The 3.2 version is still available as unicodedata.db_3_2_0
2286 for applications that require this specific version (such as IDNA).
2287
Neal Norwitzb62c4332006-03-04 18:35:47 +00002288- The timing module is no longer built by default. It was deprecated
2289 in PEP 4 in Python 2.0 or earlier.
2290
Guido van Rossum1968ad32006-02-25 22:38:04 +00002291- Patch 1433928: Added a new type, defaultdict, to the collections module.
2292 This uses the new __missing__ hook behavior added to dict (see above).
2293
Georg Brandldbd83392006-02-20 09:42:33 +00002294- Bug #854823: socketmodule now builds on Sun platforms even when
2295 INET_ADDRSTRLEN is not defined.
2296
Georg Brandlf4f44152006-02-18 22:29:33 +00002297- Patch #1393157: os.startfile() now has an optional argument to specify
2298 a "command verb" to invoke on the file.
2299
Neal Norwitz082b2df2006-02-07 07:04:46 +00002300- Bug #876637, prevent stack corruption when socket descriptor
2301 is larger than FD_SETSIZE.
2302
Neal Norwitz0e6bc8c2006-02-05 05:45:43 +00002303- Patch #1407135, bug #1424041: harmonize mmap behavior of anonymous memory.
2304 mmap.mmap(-1, size) now returns anonymous memory in both Unix and Windows.
2305 mmap.mmap(0, size) should not be used on Windows for anonymous memory.
2306
Martin v. Löwis57a34e82006-02-04 19:12:37 +00002307- Patch #1422385: The nis module now supports access to domains other
2308 than the system default domain.
2309
Martin v. Löwis14694662006-02-03 12:54:16 +00002310- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2311 are reported, the limit on path name lengths is removed, and stat reports
2312 WindowsError now (instead of OSError).
2313
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002314- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.
2315
Neal Norwitz62a21122006-01-25 05:21:55 +00002316- Bug #1413192, fix seg fault in bsddb if a transaction was deleted
2317 before the env.
2318
Martin v. Löwis11017b12006-01-14 18:12:57 +00002319- Patch #1103116: Basic AF_NETLINK support.
2320

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002448- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2449 been renamed to have only a single underscore prefix. This was done to
2450 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002451
Nick Coghlan43832302006-04-23 17:04:07 +00002452- PEP 338: new module runpy defines a run_module function to support
2453 executing modules which provide access to source code or a code object
2454 via the PEP 302 import mechanisms.
2455
Anthony Baxter93f5b932006-04-03 08:05:07 +00002456- The email module's parsedate_tz function now sets the daylight savings

2464 in attribute values.
2465
Anthony Baxterc51ee692006-04-01 00:57:31 +00002466- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002467 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002468 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002469 module will not be built.
2470
Tim Petersc17976e2006-04-01 00:26:53 +00002471- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2472 aren't officially supported here, and trying to use them will probably
2473 raise an exception some day. But dicts have been allowed, and "mostly
2474 worked", so support for them won't go away without warning.
2475
Georg Brandl338ef7d2006-03-31 18:42:16 +00002476- Bug #1445068: getpass.getpass() can now be given an explicit stream

2494
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002495- email 4.0 package now integrated. This is largely the same as the email 3.0
2496 package that was included in Python 2.3, except that PEP 8 module names are
2497 now used (e.g. mail.message instead of email.Message). The MIME classes
2498 have been moved to a subpackage (e.g. email.mime.text instead of
2499 email.MIMEText). The old names are still supported for now. Several
2500 deprecated Message methods have been removed and lots of bugs have been
2501 fixed. More details can be found in the email package documentation.
2502
Walter Dörwald40108c92006-03-27 08:15:44 +00002503- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2504 (a subclass of tuple) that provides incremental decoders and encoders
2505 (a way to use stateful codecs without the stream API). Python functions
2506 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2507 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2508 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00002510- Patch #1359365: Calling next() on a closed StringIO.String object raises
2511 a ValueError instead of a StopIteration now (like file and cString.String do).
2512 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2513 called before (like file and StringIO.StringIO do).

Brett Cannon3cbd0382005-12-16 22:49:23 +00002586- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00002587 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2588 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2589 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2590 Ronald L. Rivest offered this advice for Python:
2591
2592 "The consensus of researchers in this area (at least as
2593 expressed at the NIST Hash Function Workshop 10/31/05),
2594 is that SHA-256 is a good choice for the time being, but
2595 that research should continue, and other alternatives may
2596 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002597

2651 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002652 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002653

2691 Bug #1224621.
2692
Raymond Hettinger68c04532005-06-10 11:05:19 +00002693- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002694 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002695 the generate_tokens() function now accepts a callable argument that
2696 terminates by raising StopIteration.
2697
Georg Brandl9166e1a2005-06-04 09:20:03 +00002698- Bug #1196315: fix weakref.WeakValueDictionary constructor.

2706 class at all.
2707
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002708- distutils.commands.upload was added to support uploading distribution

2712 them to PyPI.
2713
Raymond Hettinger267b8682005-03-27 10:47:39 +00002714- decimal operator and comparison methods now return NotImplemented
2715 instead of raising a TypeError when interacting with other types. This
2716 allows other classes to implement __radd__ style methods and have them
2717 work as expected.
2718
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002719- Bug #1163325: Decimal infinities failed to hash. Attempting to
2720 hash a NaN raised an InvalidOperation instead of a TypeError.
2721
Tim Petersecc6e6a2005-07-10 22:30:55 +00002722- Patch #918101: Add tarfile open mode r|* for auto-detection of the

2756
Guido van Rossumd0641422005-02-03 15:01:24 +00002757- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2758 disables recursive traversal through instance attributes, which can
2759 be exploited in various ways.
2760
Tim Peterse3547fd2005-12-16 23:13:57 +00002761- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002762 flags on the HTTP listening socket.
2763
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002764- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2765 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2766

2773
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002774- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2775
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002776- Enhancements to the csv module:
2777
2778 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002779 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002780 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002781 + Dialect parameter parsing has been re-implemented to improve error
2782 reporting.
2783 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2784 dictates.
2785 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002786 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002787 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002788 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2789 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002790 + reader now allows \r characters to be quoted (previously it only allowed
2791 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002792 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002793 + Dialect classes passed to the module are no longer instantiated by
2794 the module before being parsed (the former validation scheme required
2795 this, but the mechanism was unreliable).
2796 + The dialect registry now contains instances of the internal
2797 C-coded dialect type, rather than references to python objects.
2798 + the internal c-coded dialect type is now immutable.
2799 + register_dialect now accepts the same keyword dialect specifications
2800 as the reader and writer, allowing the user to register dialects
2801 without first creating a dialect class.
2802 + a configurable limit to the size of parsed fields has been added -
2803 previously, an unmatched quote character could result in the entire
2804 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002805 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002806 the parser field size limit (returning the former limit). The initial
2807 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002808 + A line_num attribute has been added to the reader object, which tracks
2809 the number of lines read from the source iterator. This is not
2810 the same as the number of records returned, as records can span
2811 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002812 + reader and writer objects were not being registered with the cyclic-GC.
2813 This has been fixed.
2814
Brett Cannone6539c42005-01-08 02:43:53 +00002815- _DummyThread objects in the threading module now delete self.__block that is
2816 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2817 lock primitives tend to be limited in number and thus should not be wasted on
2818 a _DummyThread object. Fixes bug #1089632.
2819
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002820- The imghdr module now detects Exif files.
2821
Raymond Hettinger6065d322004-12-20 23:51:53 +00002822- StringIO.truncate() now correctly adjusts the size attribute.
2823 (Bug #951915).
2824
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002825- locale.py now uses an updated locale alias table (built using
2826 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2827 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002828 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002829
Raymond Hettinger3557f422004-12-07 12:02:02 +00002830- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2831
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002832- the pickle module no longer accepts the deprecated None option in the
2833 args tuple returned by __reduce__().
2834
Brett Cannon84667c02004-12-07 03:25:18 +00002835- optparse now optionally imports gettext. This allows its use in setup.py.
2836
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002837- the pickle module no longer uses the deprecated bin parameter.
2838
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002839- the shelve module no longer uses the deprecated binary parameter.
2840
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002841- the pstats module no longer uses the deprecated ignore() method.
2842
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002843- the filecmp module no longer uses the deprecated use_statcache argument.
2844
Raymond Hettinger664347b2004-12-04 21:21:53 +00002845- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2846 extended or overridden by subclasses. Formerly, the subclassed method would
2847 be ignored by the rest of the module. (Bug #1078905).
2848
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002849- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002850 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002851
Walter Dörwald36733692004-12-22 12:50:50 +00002852- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2853 once when a size argument is given. This prevents a buffer overflow in the
2854 tokenizer with very long source lines.
2855
Barry Warsaw538561e2006-01-01 21:48:54 +00002856- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2857 immediately after creating the object, without any intervening
2858 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002859
Skip Montanaro05885812005-01-16 20:48:27 +00002860- The reconvert.quote function can now emit triple-quoted strings. The
2861 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002862
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002863- ``UserString.MutableString`` now supports negative indices in
2864 ``__setitem__`` and ``__delitem__``
2865
Greg Ward40407942005-03-05 02:53:17 +00002866- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2867 correctly.
2868
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002869- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2870 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2871 character even if the user has passed a size parameter to get a proper
2872 line ending. Remove the special handling of a "\r\n" that has been split
2873 between two lines.
2874
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002875- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2876 about illegal code points. The codec now supports PEP 293 style error
2877 handlers.
2878
Walter Dörwald78a78b02005-09-01 12:04:29 +00002879- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002880 from the input stream, so that the output is a byte string in the correct
2881 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002882
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002883- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2884 considering it exactly like a '*'.
2885
Walter Dörwald007f8df2005-10-09 19:42:27 +00002886- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2887 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002888
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002889- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2890
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002891- Patch #1413711: Certain patterns of differences were making difflib
2892 touch the recursion limit.
2893
Walter Dörwald58917a62006-03-31 15:26:22 +00002894- Bug #947906: An object oriented interface has been added to the calendar
2895 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002896 called as a script (e.g. via ``python -mcalendar``). Localized month and
2897 weekday names can be ouput (even if an exotic encoding is used) using
2898 special classes that use unicode.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002900Build
2901-----
2902
Neal Norwitz602d3392006-03-31 08:21:40 +00002903- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2904 by using -mieee gcc option.
2905

2907
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002908- Build support for Win64-AMD64 was added.
2909
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002910- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2911
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002912- Patch #881820: look for openpty and forkpty also in libbsd.
2913
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002914- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2915 The zlib module is now builtin on Windows.
2916
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002917- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2918
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002919- Bug #1189330: configure did not correctly determine the necessary
2920 value of LINKCC if python was built with GCC 4.0.
2921
Trent Mick8321b422005-07-26 02:29:21 +00002922- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2923 vulnerability in zlib 1.2.1 and 1.2.2.
2924
Brett Cannon08cd5982005-04-24 22:26:38 +00002925- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2926 flags that change binary compatibility. Changes were also made to
2927 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002928 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002929
Bob Ippolitoed233462005-03-29 13:47:59 +00002930- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2931 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2932 no longer exists). This configure patch makes things right.
2933
Martin v. Löwise2713be2005-03-08 15:03:08 +00002934- Bug #1158607: Build with --disable-unicode again.
2935
Brett Cannon46d96232005-02-16 00:07:19 +00002936- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2937 defined. Discovered as a result of not being able to build on OS X.
2938
Brett Cannon516592f2004-12-07 00:42:59 +00002939- setup.py now uses the directories specified in LDFLAGS using the -L option
2940 and in CPPFLAGS using the -I option for adding library and include
2941 directories, respectively, for compiling extension modules against. This has
2942 led to the core being compiled using the values in CPPFLAGS. It also removes
2943 the need for the special-casing of both DarwinPorts and Fink for darwin since
2944 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2945 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2946 Fink, ``-I/opt/local/include`` for DarwinPorts).
2947
Brett Cannon43802422005-02-10 20:48:03 +00002948- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2949 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2950 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2951 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002953C API
2954-----
2955
Tim Petersc9d78aa2006-03-26 23:27:58 +00002956- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2957 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2958 is obtained via the ``PyObject_`` family, it must be released via the
2959 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2960 always been officially true, but when Python's small-object allocator was
2961 introduced, an attempt was made to cater to a few extension modules
2962 discovered at the time that obtained memory via ``PyObject_New`` but
2963 released it via ``PyMem_DEL``. It's years later, and if such code still
2964 exists it will fail now (probably with segfaults, but calling wrong
2965 low-level memory management functions can yield many symptoms).
2966
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002967- Added a C API for set and frozenset objects.
2968
Raymond Hettinger66517482004-12-03 11:45:13 +00002969- Removed PyRange_New().
2970
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00002971- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
2972 mapping argument now. This string is used as a mapping table. Byte values
2973 greater than the length of the string and 0xFFFE are treated as undefined
2974 mappings.

2979
Martin v. Löwis4d394df2005-01-23 09:19:22 +00002980- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002981
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00002982- Patch #1276356: New resource "urlfetch" is implemented. This enables
2983 even impatient people to run tests that require remote files.
