Georg Brandl2134e752007-05-21 20:34:16 +000035- Patch #1686487: you can now pass any mapping after '**' in function
36 calls.
37
Collin Winter62903052007-05-18 23:11:24 +000038- except clauses may now be spelled either "except E, target:" or
39 "except E as target:". This is to provide forwards compatibility with

41
Brett Cannon229cee22007-05-05 01:34:02 +000042- Deprecate BaseException.message as per PEP 352.

45 inherited from a builtin base.
46
Vinay Sajip8549ce32007-05-06 17:53:37 +000047- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +000048 setting a plain string, ie don't expand to single letter identifiers.
49
Raymond Hettinger13936692007-04-11 18:40:58 +000050- Request #1191699: Slices can now be pickled.
51
Raymond Hettinger4db5fe92007-04-12 04:10:00 +000052- Request #1193128: str.translate() now allows a None argument for

54 remaining characters.
55
Georg Brandl5cb76c12007-03-21 09:00:39 +000056- Patch #1682205: a TypeError while unpacking an iterable is no longer

58
Neal Norwitzaa754b72007-03-21 06:39:48 +000059- Remove unused file Python/fmod.c.
60
Guido van Rossum143b5642007-03-23 04:58:42 +000061- Bug #1683368: The object.__init__() and object.__new__() methods are
62 now stricter in rejecting excess arguments. The only time when
63 either allows excess arguments is when it is not overridden and the
64 other one is. For backwards compatibility, when both are
65 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +000066 warning later). Also, type.__init__() insists on the same signature
67 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +000068
Georg Brandl2b869942007-03-17 16:08:45 +000069- Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
70 to complex using its __complex__() method before falling back to the
71 __float__() method. Therefore, the functions in the cmath module now
72 can operate on objects that define a __complex__() method.
73
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +000074- Patch #1623563: allow __class__ assignment for classes with __slots__.
75 The old and the new class are still required to have the same slot names.
76
Collin Winter77c67bd2007-03-16 04:11:30 +000077- Patch #1642547: Fix an error/crash when encountering syntax errors in
78 complex if statements.
79
Žiga Seilnacht20f43d32007-03-15 11:44:55 +000080- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
81 is called with an object that is faking its type.
82
Žiga Seilnacht71436f02007-03-14 12:24:09 +000083- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
84 name.
85
Georg Brandl5240d742007-03-13 20:46:32 +000086- Patch #1444529: the builtin compile() now accepts keyword arguments.
87
Georg Brandl7b9c5552007-03-12 14:30:05 +000088- Bug #1678647: write a newline after printing an exception in any
89 case, even when converting the value to a string failed.
90
Georg Brandl871f1bc2007-03-12 13:17:36 +000091- The dir() function has been extended to call the __dir__() method on
92 its argument, if it exists. If not, it will work like before. This allows
93 customizing the output of dir() in the presence of a __getattr__().
94
Collin Winter276887b2007-03-12 16:11:39 +000095- Patch #922167: Python no longer segfaults when faced with infinitely
96 self-recursive reload() calls (as reported by bug #742342).
97
Žiga Seilnacht89032082007-03-11 15:54:54 +000098- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
99
Collin Wintere38051d2007-03-09 20:33:07 +0000100- Patch #1491866: change the complex() constructor to allow parthensized
101 forms. This means complex(repr(x)) now works instead of raising a
102 ValueError.
103
Georg Brandlaa2321b2007-03-07 00:40:28 +0000104- Patch #703779: unset __file__ in __main__ after running a file. This
105 makes the filenames the warning module prints much more sensible when
106 a PYTHONSTARTUP file is used.
107
Georg Brandl49aafc92007-03-07 00:34:46 +0000108- Variant of patch #697613: don't exit the interpreter on a SystemExit
109 exception if the -i command line option or PYTHONINSPECT environment
110 variable is given, but break into the interactive interpreter just like
111 on other exceptions or normal program exit.
112
Georg Brandl00cd8182007-03-06 18:41:12 +0000113- Patch #1638879: don't accept strings with embedded NUL bytes in long().
114
Georg Brandl098cd692007-03-06 12:17:50 +0000115- Bug #1674503: close the file opened by execfile() in an error condition.
116
Georg Brandl0fca97a2007-03-05 22:28:08 +0000117- Patch #1674228: when assigning a slice (old-style), check for the
118 sq_ass_slice instead of the sq_slice slot.
119
Neal Norwitz88516a62007-02-26 22:41:45 +0000120- When printing an unraisable error, don't print exceptions. before the name.
121 This duplicates the behavior whening normally printing exceptions.
122
Martin v. Löwisfd963262007-02-09 12:19:32 +0000123- Bug #1653736: Properly discard third argument to slot_nb_inplace_power.
124
Brett Cannon129bd522007-01-30 21:34:36 +0000125- PEP 352: Raising a string exception now triggers a TypeError. Attempting to
126 catch a string exception raises DeprecationWarning.
127
Brett Cannonf5bee302007-01-23 23:21:22 +0000128- Bug #1377858: Fix the segfaulting of the interpreter when an object created
129 a weakref on itself during a __del__ call for new-style classes (classic
130 classes still have the bug).
131
Martin v. Löwis6c5c5022007-01-23 21:11:47 +0000132- Bug #1579370: Make PyTraceBack_Here use the current thread, not the

166
Neal Norwitzcbeb6872006-10-14 21:33:38 +0000167- Update the peephole optimizer to remove more dead code (jumps after returns)
168 and inline unconditional jumps to returns.
169
Georg Brandl2c1375c2006-10-12 11:27:59 +0000170- Bug #1545497: when given an explicit base, int() did ignore NULs
171 embedded in the string to convert.
172
Georg Brandl846f73a2006-10-08 07:11:54 +0000173- Bug #1569998: break inside a try statement (outside a loop) is now
174 recognized and rejected.
175
Armin Rigo7ccbca92006-10-04 12:17:45 +0000176- list.pop(x) accepts any object x following the __index__ protocol.
177
178- Fix some leftovers from the conversion from int to Py_ssize_t
179 (relevant to strings and sequences of more than 2**31 items).

181- A number of places, including integer negation and absolute value,
182 were fixed to not rely on undefined behaviour of the C compiler
183 anymore.

201
Brett Cannon9adeab72006-09-20 18:34:28 +0000202- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This

204
Georg Brandlec6c2df2006-09-11 09:38:35 +0000205- Make _PyGILState_NoteThreadState() static, it was not used anywhere

306 (as opposed to the command line) will now write file names ending in
307 ".cpp" too.
308
Facundo Batistad918a652007-04-24 13:54:38 +0000309- As specified in RFC 2616, an HTTP response like 2xx indicates that

324 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +0000325 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +0000326

339 GNOME or KDE browser, depending on whether there is a session of one
340 of those present. Also, it tries the Windows default browser before
341 trying Mozilla variants.
342
Collin Winter6f187742007-03-16 22:16:08 +0000343- Patch #1339796: add a relpath() function to os.path.

Collin Winterfaaa2042007-03-10 03:35:34 +0000414 be equal to calling getsockname() on the server's socket. Fixed by
415 patch #1545011.
Collin Winter22c42ba2007-03-10 02:51:26 +0000416

432
Georg Brandl9caadf82007-03-08 18:37:31 +0000433- unittest now verifies more of its assumptions. In particular, TestCase
434 and TestSuite subclasses (not instances) are no longer accepted in

468 import semantics.

979
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000980- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000981 compared equal or unequal to a string and a UnicodeDecodeError
982 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000983
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000984 Instead, the equal (==) and unequal (!=) comparison operators will
985 now issue a UnicodeWarning and interpret the two objects as
986 unequal. The UnicodeWarning can be filtered as desired using
987 the warning framework, e.g. silenced completely, turned into an
988 exception, logged, etc.
989
990 Note that compare operators other than equal and unequal will still
991 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000992
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000993- Fix segfault when doing string formatting on subclasses of long.
994
995- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
996 with new-style classes.
997
998- Fix bug related to __len__ functions returning negative values with
999 classic classes.
1000
1001- Patch #1538606, Fix __index__() clipping. There were some problems
1002 discovered with the API and how integers that didn't fit into Py_ssize_t
1003 were handled. This patch attempts to provide enough alternatives
1004 to effectively use __index__.
1005
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001006- Bug #1536021: __hash__ may now return long int; the final hash
1007 value is obtained by invoking hash on the long int.
1008
Thomas Hellerab1049c2006-08-08 17:37:00 +00001009- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1010
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001011- Bug #1535165: fixed a segfault in input() and raw_input() when
1012 sys.stdin is closed.
1013
Thomas Heller74d36f02006-08-04 18:17:40 +00001014- On Windows, the PyErr_Warn function is now exported from
1015 the Python dll again.
1016
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001017- Bug #1191458: tracing over for loops now produces a line event
1018 on each iteration. Fixing this problem required changing the .pyc
1019 magic number. This means that .pyc files generated before 2.5c1
1020 will be regenerated.
1021
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001022- Bug #1333982: string/number constants were inappropriately stored
1023 in the byte code and co_consts even if they were not used, ie
1024 immediately popped off the stack.
1025
Georg Brandle9462c72006-08-04 18:03:37 +00001026- Fixed a reference-counting problem in property().

1029Library
1030-------
1031
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001032- Fix a bug in the ``compiler`` package that caused invalid code to be
1033 generated for generator expressions.
1034
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001035- The distutils version has been changed to 2.5.0. The change to
1036 keep it programmatically in sync with the Python version running
1037 the code (introduced in 2.5b3) has been reverted. It will continue
1038 to be maintained manually as static string literal.
1039
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001040- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001041 and this cannot be converted to the required C type, an exception is
1042 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001043 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001044
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001045- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001046 an exception.
1047
Tim Petersc10c9d02006-09-05 02:18:09 +00001048- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001049 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001050 workarounds for clocks with low resolution, to stop the code yielding
1051 duplicate UUIDs.
1052
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001053- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1054 before raising SystemExit, allowing IDLE to honor quit() and exit().
1055
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001056- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1057
Georg Brandl7a1af772006-08-14 21:55:28 +00001058- Patch #1536071: trace.py should now find the full module name of a
1059 file correctly even on Windows.
1060
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001061- logging's atexit hook now runs even if the rest of the module has
1062 already been cleaned up.
1063
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001064- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001065
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001066- Bug #1531405, format_exception no longer raises an exception if
1067 str(exception) raised an exception.
1068
Neil Schemenauer06ded092006-08-04 16:20:30 +00001069- Fix a bug in the ``compiler`` package that caused invalid code to be
1070 generated for nested functions.

Georg Brandl3335a7a2006-08-14 21:42:55 +00001078- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
1079 raises the correct exceptions.
1080
Thomas Heller1ce433e2006-08-14 16:20:04 +00001081- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1082 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1083
Thomas Heller86720042006-08-14 11:17:48 +00001084- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1085 uses the _as_parameter_ attribute when objects are passed to foreign
1086 function calls. The ctypes version number was changed to 1.0.1.
1087
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001088- Bug #1530559, struct.pack raises TypeError where it used to convert.
1089 Passing float arguments to struct.pack when integers are expected
1090 now triggers a DeprecationWarning.

1141-----------------
1142
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001143- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001144 returned a long (see PEP 353).
1145
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001146- Bug #1515471: string.replace() accepts character buffers again.
1147
Neal Norwitz07aadb12006-07-30 06:55:48 +00001148- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1149 This provides the proper warning for struct.pack().
1150 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1151
Neal Norwitz0d62a062006-07-30 06:53:31 +00001152- Patch #1531113: Fix augmented assignment with yield expressions.
1153 Also fix a SystemError when trying to assign to yield expressions.
1154
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001155- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1156 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1157 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1158 excessive filesystem operations during imports.
1159
Tim Petersbc24eee2006-07-27 01:14:53 +00001160- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1161 operations on signed longs that are formally undefined by C.
1162 Unfortunately, at least one compiler now cares about that, so complicated
1163 the code to make that compiler happy again.
1164
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001165- Bug #1524310: Properly report errors from FindNextFile in os.listdir.

1175 had more than 255 blank lines.
1176
Georg Brandl9dceedb2006-07-12 15:31:17 +00001177- Patch #1521179: Python now accepts the standard options ``--help`` and
1178 ``--version`` as well as ``/?`` on Windows.
1179
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001180- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001181 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001182 This means that .pyc files generated before 2.5b3 will be regenerated.

Tim Peters112aad32006-07-19 00:03:19 +00001184- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001185 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001186 new ``sys._current_frames()`` returns a dictionary with one entry,
1187 mapping the faux "thread id" 0 to the current frame.

1193-------
1194
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001195- Correction of patch #1455898: In the mbcs decoder, set final=False
1196 for stream decoder, but final=True for the decode function.
1197
Georg Brandl07fec3a2006-08-01 18:49:24 +00001198- os.urandom no longer masks unrelated exceptions like SystemExit or
1199 KeyboardInterrupt.
1200
Tim Peters4643c2f2006-08-10 22:45:34 +00001201- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001202 shutil.copytree on Windows
1203
Georg Brandle34ac7c2006-07-30 11:07:23 +00001204- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1205 refers to file descriptors, not file objects.
1206
Tim Petersc10c9d02006-09-05 02:18:09 +00001207- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001208 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001209 #1513611, and probably others.
1210
Georg Brandledd9b0d2006-07-29 09:33:26 +00001211- Bug #1441397: The compiler module now recognizes module and function
1212 docstrings correctly as it did in Python 2.4.
1213
Tim Peters6f681472006-07-27 23:44:37 +00001214- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1215 lost that tests are sorted by name before being run. This rarely
1216 matters for well-written tests, but can create baffling symptoms if
1217 side effects from one test to the next affect outcomes. ``DocTestFinder``
1218 has been changed to sort the list of tests it returns.
1219
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001220- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001221 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001222
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001223- Bug #978833: Really close underlying socket in _socketobject.close.
1224
Georg Brandl8c036cc2006-08-20 13:15:39 +00001225- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1226 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001227
Georg Brandlcf0c1722006-07-26 07:23:32 +00001228- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1229 to recursive calls and call it with the failing package name.
1230
Martin v. Löwis0b483032006-07-25 09:53:12 +00001231- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1232
Georg Brandlc13c34c2006-07-24 14:09:56 +00001233- Patch #1515343: Fix printing of deprecated string exceptions with a
1234 value in the traceback module.
1235
Greg Ward48fae7a2006-07-23 16:05:51 +00001236- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1237
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001238- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1239
Brett Cannoncaebe222006-07-18 04:41:36 +00001240- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1241 argument tuple. For arguments where zero is illegal, the value is forced to
1242 the minimum value that is correct. This is to support an undocumented but
1243 common way people used to fill in inconsequential information in the time
1244 tuple pre-2.4.
1245
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001246- Patch #1220874: Update the binhex module for Mach-O.
1247
Barry Warsawb110bad2006-07-21 14:51:07 +00001248- The email package has improved RFC 2231 support, specifically for
1249 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1250 (name*0=<blah>) parameter continuations. This may change the types of
1251 values returned from email.message.Message.get_param() and friends.
1252 Specifically in some cases where non-encoded continuations were used,
1253 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1254 will just return the string (since non-encoded continuations don't have
1255 charset and language parts).
1256
1257 Also, whereas % values were decoded in all parameter continuations, they are
1258 now only decoded in encoded parameter parts.
1259
Ronald Oussoren3075e162006-07-25 20:28:55 +00001260- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1261
1262- Bug #1517996: IDLE now longer shows the default Tk menu when a
1263 path browser, class browser or debugger is the frontmost window on MacOS X
1264
Barry Warsaw00decd72006-07-27 23:43:15 +00001265- Patch #1520294: Support for getset and member descriptors in types.py,
1266 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1267 of an object against these built-in types and more importantly, for getting
1268 their docstrings printed in the interactive interpreter's help() function.

1272-----------------
1273
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001274- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1275 a socket operation on a socket with a timeout, the exception will be
1276 caught correctly. Previously, the exception was not caught.
1277
Thomas Heller1393d6a2006-07-28 21:43:20 +00001278- Patch #1529514: The _ctypes extension is now compiled on more
1279 openbsd target platforms.
1280
Tim Peters9cab5932006-07-28 00:30:00 +00001281- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1282 a memory leak, affecting pickles and deep copies.
1283
Tim Petersbc24eee2006-07-27 01:14:53 +00001284- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1286
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001287- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1288
Thomas Hellerce049a02006-07-14 17:51:14 +00001289- Patch #1521817: Index range checking on ctypes arrays containing
1290 exactly one element enabled again. This allows iterating over these
1291 arrays, without the need to check the array size before.
1292
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001293- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001294 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001295 /dev/null in certain cases; this is now fixed.
1296
Thomas Heller47d7a062006-07-12 08:43:47 +00001297- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1298 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001299
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001300- Because of a misspelled preprocessor symbol, ctypes was always
1301 compiled without thread support; this is now fixed.
1302
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001303- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1304 methods now allow their database parameter to be None as the
1305 sleepycat API allows.
1306
Matt Flemingec926502006-07-28 11:27:27 +00001307- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1308 bluetooth API compared with Linux and FreeBSD.
1309
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001310Tests
1311-----
1312
1313- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1314 how long the test file should take to play. Now accepts taking 2.93 secs
1315 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1316
Georg Brandl4793aa32006-07-28 18:31:39 +00001317- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1318 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1319 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001326Mac
1327---
1328
1329- PythonLauncher now works correctly when the path to the script contains
1330 characters that are treated specially by the shell (such as quotes).
1331
1332- Bug #1527397: PythonLauncher now launches scripts with the working directory
1333 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001334 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001335 expect.

1344-----------------
1345
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001346- Bug #1441486: The literal representation of -(sys.maxint - 1)
1347 again evaluates to a int object, not a long.
1348
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001349- Bug #1501934: The scope of global variables that are locally assigned
1350 using augmented assignment is now correctly determined.
1351
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001352- Bug #927248: Recursive method-wrapper objects can now safely
1353 be released.
1354
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001355- Bug #1417699: Reject locale-specific decimal point in float()
1356 and atof().
1357
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001358- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1359 omit a default "error" argument for NULL pointer. This allows
1360 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001361
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001362- Bug #1519018: 'as' is now validated properly in import statements.
1363
Neal Norwitz28746ab2006-07-09 22:14:42 +00001364- On 64 bit systems, int literals that use less than 64 bits are
1365 now ints rather than longs.
1366
Neal Norwitzed657552006-07-10 00:04:44 +00001367- Bug #1512814, Fix incorrect lineno's when code at module scope
1368 started after line 256.
1369
Tim Peters32a83612006-07-10 21:08:24 +00001370- New function ``sys._current_frames()`` returns a dict mapping thread
1371 id to topmost thread stack frame. This is for expert use, and is
1372 especially useful for debugging application deadlocks. The functionality
1373 was previously available in Fazal Majid's ``threadframe`` extension
1374 module, but it wasn't possible to do this in a wholly threadsafe way from
1375 an extension.

1384
Tim Peters32a83612006-07-10 21:08:24 +00001385- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001386 environment variable to be set in order to the SDK environment
1387 for finding the compiler, include files, etc.

1392
Thomas Woutersadd19112006-07-05 11:03:49 +00001393- string.Template() now correctly handles tuple-values. Previously,
1394 multi-value tuples would raise an exception and single-value tuples would
1395 be treated as the value they contain, instead.
1396
Martin v. Löwisede77f52006-07-03 13:01:35 +00001397- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1399
Martin v. Löwis45482392006-07-03 12:28:58 +00001400- Bug #1267547: Put proper recursive setup.py call into the
1401 spec file generated by bdist_rpm.
1402
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001403- Bug #1514693: Update turtle's heading when switching between
1404 degrees and radians.
1405
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001406- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001407 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001408
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001409- Bug #1514703: Only setup canvas window in turtle when the canvas
1410 is created.
1411
Martin v. Löwis7596e832006-07-01 15:33:37 +00001412- Bug #1513223: .close() of a _socketobj now releases the underlying
1413 socket again, which then gets closed as it becomes unreferenced.
1414
Fred Drake10497c82006-06-29 02:57:48 +00001415- Bug #1504333: Make sgmllib support angle brackets in quoted
1416 attribute values.
1417
1418- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1419 sgmllib ('[' and ']' were not accepted).
1420
Georg Brandl1be63af2006-06-28 20:23:25 +00001421- Fix a bug in the turtle module's end_fill function.
1422
Brett Cannon53ab5b72006-06-22 16:49:14 +00001423- Bug #1510580: The 'warnings' module improperly required that a Warning
1424 category be either a types.ClassType and a subclass of Warning. The proper
1425 check is just that it is a subclass with Warning as the documentation states.
1426
Georg Brandlad29e632006-06-21 17:45:17 +00001427- The compiler module now correctly compiles the new try-except-finally
1428 statement (bug #1509132).
1429
Neal Norwitz60373cd2006-06-22 06:30:50 +00001430- The wsgiref package is now installed properly on Unix.
1431
Vinay Sajip28e57612006-07-01 10:45:20 +00001432- A bug was fixed in logging.config.fileConfig() which caused a crash on
1433 shutdown when fileConfig() was called multiple times.
1434
Gerhard Häring762fbd32006-07-02 17:48:30 +00001435- The sqlite3 module did cut off data from the SQLite database at the first
1436 null character before sending it to a custom converter. This has been fixed
1437 now.

1440-----------------
1441
Tim Peters112aad32006-07-19 00:03:19 +00001442- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1443 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1444 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001445
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001446- Assigning None to pointer type fields in ctypes structures possible
1447 overwrote the wrong fields, this is fixed now.
1448
1449- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1450 on non-Windows platforms.
1451
1452- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1453 integer or long, without range checking.
1454
1455- Patch #1517790: It is now possible to use custom objects in the ctypes
1456 foreign function argtypes sequence as long as they provide a from_param
1457 method, no longer is it required that the object is a ctypes type.
1458
1459- The '_ctypes' extension module now works when Python is configured
1460 with the --without-threads option.
1461
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001462- Bug #1513646: os.access on Windows now correctly determines write
1463 access, again.
1464
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001465- Bug #1512695: cPickle.loads could crash if it was interrupted with

1477
Tim Peters32a83612006-07-10 21:08:24 +00001478- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001479 Previously, the slight difference could cause compilation errors of the
1480 'zlib' module on systems with more than one version of zlib.
1481
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001482- The MSI compileall step was fixed to also support a TARGETDIR

Anthony Baxterd1136802006-06-19 12:04:15 +00001511*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +00001512
1513Core and builtins
1514-----------------
1515
Georg Brandla56b9152006-06-19 06:35:54 +00001516- Patch #1507676: Error messages returned by invalid abstract object operations
1517 (such as iterating over an integer) have been improved and now include the
1518 type of the offending object to help with debugging.
1519
Brett Cannonea3912b2006-06-13 21:46:41 +00001520- Bug #992017: A classic class that defined a __coerce__() method that returned
1521 its arguments swapped would infinitely recurse and segfault the interpreter.
1522
Neal Norwitz909eb122006-06-12 02:13:21 +00001523- Fix the socket tests so they can be run concurrently.
1524
Neal Norwitzb9845e72006-06-12 02:11:18 +00001525- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001526 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001527
Brett Cannon22565aa2006-06-09 22:31:23 +00001528- Bug #532646: object.__call__() will continue looking for the __call__
1529 attribute on objects until one without one is found. This leads to recursion
1530 when you take a class and set its __call__ attribute to an instance of the
1531 class. Originally fixed for classic classes, but this fix is for new-style.
1532 Removes the infinite_rec_3 crasher.
1533
Georg Brandl24250812006-06-09 18:45:48 +00001534- The string and unicode methods startswith() and endswith() now accept
1535 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1536
Brett Cannonde3b0522006-06-08 17:00:45 +00001537- Buffer objects, at the C level, never used the char buffer
1538 implementation even when the char buffer for the wrapped object was
1539 explicitly requested (originally returned the read or write buffer).
1540 Now a TypeError is raised if the char buffer is not present but is
1541 requested.
1542
Georg Brandlddbaa662006-06-04 21:56:52 +00001543- Patch #1346214: Statements like "if 0: suite" are now again optimized
1544 away like they were in Python 2.4.
1545
Georg Brandlb7c8f542006-05-27 12:30:25 +00001546- Builtin exceptions are now full-blown new-style classes instead of
1547 instances pretending to be classes, which speeds up exception handling
1548 by about 80% in comparison to 2.5a2.
1549
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001550- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1551 Unicode 4.1.
1552
Georg Brandlf4ef1162006-05-26 18:03:31 +00001553- Patch #921466: sys.path_importer_cache is now used to cache valid and
1554 invalid file paths for the built-in import machinery which leads to
1555 fewer open calls on startup.
1556
Tim Peters696cf432006-05-24 21:10:40 +00001557- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1558 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1559 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1560 the number of input digits (it was and remains linear-time for bases
1561 2, 4, 8, 16 and 32).
1562
Tim Petersb713ec22006-05-23 18:45:30 +00001563- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1564 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1565 an integer close to ``sys.maxint``. This was repaired by patch
1566 #1335972, which also gives a nice speedup.
1567
Richard Jonescebbefc2006-05-23 18:28:17 +00001568- Patch #1337051: reduced size of frame objects.
1569
1570- PyErr_NewException now accepts a tuple of base classes as its
1571 "base" parameter.
1572
Richard Jones7c88dcc2006-05-23 10:37:38 +00001573- Patch #876206: function call speedup by retaining allocated frame
1574 objects.
1575
Georg Brandl7b90e162006-05-18 07:01:27 +00001576- Bug #1462152: file() now checks more thoroughly for invalid mode
1577 strings and removes a possible "U" before passing the mode to the
1578 C library function.
1579
Neal Norwitz1004a532006-05-15 07:17:23 +00001580- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1581
Neal Norwitz373f0a72006-05-15 07:04:36 +00001582- Bug #1487966: Fix SystemError with conditional expression in assignment
1583
Martin v. Löwis879768d2006-05-11 13:28:43 +00001584- WindowsError now has two error code attributes: errno, which carries
1585 the error values from errno.h, and winerror, which carries the error
1586 values from winerror.h. Previous versions put the winerror.h values
1587 (from GetLastError()) into the errno attribute.
1588
Martin v. Löwis77736712006-05-04 05:51:03 +00001589- Patch #1475845: Raise IndentationError for unexpected indent.
1590
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001591- Patch #1479181: split open() and file() from being aliases for each other.
1592
Tim Peters44bd9862006-06-01 13:49:23 +00001593- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1594 methods were always silently ignored by dictionaries when comparing keys.
1595 They are now passed through (except when using the C API function
1596 ``PyDict_GetItem()``, whose semantics did not change).
1597
1598- Bug #1456209: In some obscure cases it was possible for a class with a
1599 custom ``__eq__()`` method to confuse dict internals when class instances
1600 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1601 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001603Extension Modules
1604-----------------
1605
Trent Mick960a3f82006-06-28 20:30:41 +00001606- Bug #1295808: expat symbols should be namespaced in pyexpat
1607
1608- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1609
Brett Cannon6ee7d012006-06-08 16:23:04 +00001610- Change binascii.hexlify to accept a read-only buffer instead of only a char
1611 buffer and actually follow its documentation.
1612
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001613- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1614
Nick Coghlanc649ec52006-05-29 12:43:05 +00001615- Patch #1478788 (modified version): The functional extension module has
1616 been renamed to _functools and a functools Python wrapper module added.
1617 This provides a home for additional function related utilities that are
1618 not specifically about functional programming. See PEP 309.
1619
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001620- Patch #1493701: performance enhancements for struct module.
1621
Georg Brandl378d5922006-05-17 14:26:50 +00001622- Patch #1490224: time.altzone is now set correctly on Cygwin.
1623
Georg Brandl8d3342b2006-05-16 07:38:27 +00001624- Patch #1435422: zlib's compress and decompress objects now have a
1625 copy() method.
1626
Andrew MacIntyre92913322006-06-13 15:04:24 +00001627- Patch #1454481: thread stack size is now tunable at runtime for thread
1628 enabled builds on Windows and systems with Posix threads support.
1629
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001630- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1631 (up to the system limit of 32K characters).
1632
1633- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1634 As a result, these functions now raise WindowsError instead of OSError.
1635
Tim Peters7a822da2006-05-25 21:50:17 +00001636- ``time.clock()`` on Win64 should use the high-performance Windows
1637 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1638 Windows platforms).
1639
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001640- Calling Tk_Init twice is refused if the first call failed as that
1641 may deadlock.
1642
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001643- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1644 accept it without potentially using an uninitialized pointer.
1645
1646- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1647 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1648 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001649
Gregory P. Smith372b5832006-06-05 18:48:21 +00001650- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001651 [pybsddb project SF patch number 1466734]
1652
Gregory P. Smith372b5832006-06-05 18:48:21 +00001653- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1654 parameter is supplied. [SF pybsddb bug #1477863]
1655
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001656- bsddb: the __len__ method of a DB object has been fixed to return correct
1657 results. It could previously incorrectly return 0 in some cases.
1658 Fixes SF bug 1493322 (pybsddb bug 1184012).
1659
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001660- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1661 aborts the db transaction safely when a modifier callback fails.
1662 Fixes SF python patch/bug #1408584.
1663
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001664- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001665 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001666 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1667 database calls that would previously deadlock. [SF python bug #775414]
1668
Vinay Sajip28e57612006-07-01 10:45:20 +00001669- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001670
Walter Dörwald4994d952006-06-19 08:07:50 +00001671- Patch #1506645: add Python wrappers for the curses functions
1672 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001673

1675-------
1676
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001677- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1678 functions.
1679
Martin v. Löwis3798da02006-06-17 18:44:27 +00001680- Patch #812986: Update turtle output even if not tracing.
1681
Vinay Sajip28e57612006-07-01 10:45:20 +00001682- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001683 Tkinter.BaseWidget.
1684
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001685- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1686
Martin v. Löwis337487e2006-06-17 09:15:14 +00001687- Patch #763580: Add name and value arguments to Tkinter variable
1688 classes.
1689
Georg Brandl83cc0d02006-06-14 08:50:03 +00001690- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1691 mime.types file for determining MIME types.
1692
Georg Brandl2605ca82006-06-14 06:08:31 +00001693- Bug #1339007: Shelf objects now don't raise an exception in their
1694 __del__ method when initialization failed.
1695
Martin v. Löwisd8251432006-06-14 05:21:04 +00001696- Patch #1455898: The MBCS codec now supports the incremental mode for
1697 double-byte encodings.
1698
Tim Peters43898b42006-06-14 04:09:25 +00001699- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1700 guarantee that adjacent triples in the return list always describe
1701 non-adjacent blocks. Previously, a pair of matching blocks could end
1702 up being described by multiple adjacent triples that formed a partition
1703 of the matching pair.
1704
Greg Ward0e0c9f42006-06-11 16:24:11 +00001705- Bug #1498146: fix optparse to handle Unicode strings in option help,
1706 description, and epilog.
1707
Greg Wardd1c797e2006-06-11 14:42:41 +00001708- Bug #1366250: minor optparse documentation error.
1709
Greg Ward7f547402006-06-11 00:40:49 +00001710- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1711 clarify docs.
1712
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001713- The wsgiref package has been added to the standard library.
1714
Nick Coghlan676725d2006-06-08 13:54:49 +00001715- The functions update_wrapper() and wraps() have been added to the functools
1716 module. These make it easier to copy relevant metadata from the original
1717 function when writing wrapper functions.
1718
Tim Petersd6a9eef2006-06-05 01:48:21 +00001719- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1720 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001721
Martin v. Löwis3f767792006-06-04 19:36:28 +00001722- Patch #1359618: Speed up charmap encoder by using a trie structure
1723 for lookup.
1724
Tim Petersd609b1a2006-06-02 23:22:51 +00001725- The functions in the ``pprint`` module now sort dictionaries by key
1726 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1727 if and only if its display required more than one line, although that
1728 wasn't documented. The new behavior increases predictability; e.g.,
1729 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1730
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001731- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1732 (thanks for J. J. Lee).
1733
Georg Brandl2b330372006-05-28 20:23:12 +00001734- Patch #1496206: improve urllib2 handling of passwords with respect to
1735 default HTTP and HTTPS ports.
1736
George Yoshidaf3c65de2006-05-28 16:39:09 +00001737- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1738
Bob Ippolito7298f272006-05-23 18:43:47 +00001739- Patch #1281707: speed up gzip.readline.
1740
Georg Brandlb89316f2006-05-17 15:51:16 +00001741- Patch #1180296: Two new functions were added to the locale module:
1742 format_string() to get the effect of "format % items" but locale-aware,
1743 and currency() to format a monetary number with currency sign.
1744
Georg Brandle3a25832006-05-17 14:56:04 +00001745- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1746 and several features added, such as speed and geometry control.
1747
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001748- Patch #1488881: add support for external file objects in bz2 compressed
1749 tarfiles.
1750
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001751- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1752 stdout arguments, making it possible to redirect input and output
1753 for remote debugging.
1754
1755- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1756 a couple of issues, notably handling of long file names using the
1757 GNU LONGNAME extension.
1758
1759- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1760 new flag when ``name`` is already the name of an option flag.
1761
1762- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1763 package.
1764
1765- Patch #1472854: make the rlcompleter.Completer class usable on non-
1766 UNIX platforms.
1767
1768- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1769
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001770- Bug #1472827: correctly escape newlines and tabs in attribute values in
1771 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001801What's New in Python 2.5 alpha 2?
1802=================================
1803
1804*Release date: 27-APR-2006*
1805
1806Core and builtins
1807-----------------
1808
Thomas Heller1b046642006-04-18 18:51:06 +00001809- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1810 by converting these apis from macros into exported functions again:
1811
1812 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1813 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1814 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1815 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1816 PyRun_String Py_CompileString
1817
Martin v. Löwis45294a92006-04-18 06:24:08 +00001818- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1819
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001820- All uses of PyStructSequence_InitType have been changed to initialize
1821 the type objects only once, even if the interpreter is initialized
1822 multiple times.
1823
Neal Norwitz61546162006-04-14 05:20:28 +00001824- Bug #1454485, array.array('u') could crash the interpreter. This was
1825 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1826 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1827
1828- Py_UNICODE is unsigned. It was always documented as unsigned, but
1829 due to a bug had a signed value in previous versions.
1830
Tim Peters3a5e8b12006-04-11 01:44:07 +00001831- Patch #837242: ``id()`` of any Python object always gives a positive
1832 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1833 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001834 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001835 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001836
Tim Peters3a5e8b12006-04-11 01:44:07 +00001837 def __hash__(self):
1838 return id(self) # WRONG
1839
1840 because a hash result must be a (short) Python int but it was always
1841 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001842 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001843 was always usable as a hash value before this patch. That's no longer
1844 necessarily so.
1845
1846- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001847 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001848 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001849 #1454844)
1850
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001851- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1852 involving generators that have paused outside of any ``try`` or ``with``
1853 blocks. (In 2.5a1, a paused generator that was part of a reference
1854 cycle could not be garbage collected, regardless of whether it was
1855 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001856
Anthony Baxter51bcb682006-04-05 14:51:42 +00001857Extension Modules
1858-----------------
1859
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001860- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1861 is a macro.
1862
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001863- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1864 fails with an error condition.
1865
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001866- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1867
1868- Bug #1117761: bsddb.*open() no longer raises an exception when using
1869 the cachesize parameter.
1870
1871- Bug #1149413: bsddb.*open() no longer raises an exception when using
1872 a temporary db (file=None) with the 'n' flag to truncate on open.
1873
1874- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1875 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001876
Armin Rigoa9017c32006-04-19 11:50:27 +00001877- Patch #1062014: AF_UNIX sockets under Linux have a special
1878 abstract namespace that is now fully supported.
1879
Anthony Baxter51bcb682006-04-05 14:51:42 +00001880Library
1881-------
1882
Peter Astrand7d1d4362006-07-14 14:04:45 +00001883- Bug #1223937: subprocess.CalledProcessError reports the exit status
1884 of the process using the returncode attribute, instead of
1885 abusing errno.
1886
Tim Peters711bf302006-04-25 03:31:36 +00001887- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1888 a doctest to be skipped (the code is not run, and the expected output
1889 or exception is ignored).
1890
Nick Coghlanda2268f2006-04-24 04:37:15 +00001891- Fixed contextlib.nested to cope with exceptions being raised and
1892 caught inside exit handlers.
1893
Greg Wardab05edc2006-04-23 03:47:58 +00001894- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1895 hex, octal, or binary; add ``append_const`` action; keep going if
1896 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1897 added ``epilog`` for better help generation).
1898
Tim Peters21fbd572006-04-21 21:18:10 +00001899- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1900 called from a thread spawned as a side effect of importing a module.
1901
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001902- The pydoc module now supports documenting packages contained in
1903 .zip or .egg files.
1904
1905- The pkgutil module now has several new utility functions, such
1906 as ``walk_packages()`` to support working with packages that are either
1907 in the filesystem or zip files.
1908
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001909- The mailbox module can now modify and delete messages from
1910 mailboxes, in addition to simply reading them. Thanks to Gregory
1911 K. Johnson for writing the code, and to the 2005 Google Summer of
1912 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001913
Tim Petersc7605f22006-04-17 21:12:33 +00001914- The ``__del__`` method of class ``local`` in module ``_threading_local``
1915 returned before accomplishing any of its intended cleanup.
1916
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001917- Patch #790710: Add breakpoint command lists in pdb.
1918
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001919- Patch #1063914: Add Tkinter.Misc.clipboard_get().
1920
Martin v. Löwis4b501e62006-04-15 08:41:11 +00001921- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1922
Anthony Baxtere29002c2006-04-12 12:07:31 +00001923- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1924 Windows. Bug #1469163.
1925
Phillip J. Eby47032112006-04-11 01:07:43 +00001926- The warnings, linecache, inspect, traceback, site, and doctest modules
1927 were updated to work correctly with modules imported from zipfiles or
1928 via other PEP 302 __loader__ objects.
1929
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001930- Patch #1467770: Reduce usage of subprocess._active to processes which
1931 the application hasn't waited on.
1932
Martin v. Löwisb04dee92006-04-10 08:34:21 +00001933- Patch #1462222: Fix Tix.Grid.
1934
Neal Norwitza31bf182006-04-09 03:35:43 +00001935- Fix exception when doing glob.glob('anything*/')
1936
Skip Montanaro262fb922006-04-21 02:31:07 +00001937- The pstats.Stats class accepts an optional stream keyword argument to
1938 direct output to an alternate file-like object.
1939
Anthony Baxter51bcb682006-04-05 14:51:42 +00001940Build
1941-----
1942
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001943- The Makefile now has a reindent target, which runs reindent.py on
1944 the library.
1945
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001946- Patch #1470875: Building Python with MS Free Compiler
1947
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001948- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001949
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001950- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1951 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001952 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001953 CXX from --with-cxx-main, see description in README.
1954
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001955- Patch #1429775: Link extension modules with the shared libpython.
1956
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001957- Fixed a libffi build problem on MIPS systems.
1958
Tim Peters8931ff12006-05-13 23:28:20 +00001959- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1960 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1961 and "%zu" for unsigned integers of type ``size_t``.
1962
Anthony Baxter51bcb682006-04-05 14:51:42 +00001963Tests
1964-----
1965
Nick Coghlanda2268f2006-04-24 04:37:15 +00001966- test_contextlib now checks contextlib.nested can cope with exceptions
1967 being raised and caught inside exit handlers.
1968
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001969- test_cmd_line now checks operation of the -m and -c command switches
1970
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001971- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1972 it separately and by hand. It also wasn't cleaning up its changes to
1973 the current Decimal context.
1974
Thomas Woutersabd08882006-04-26 15:53:30 +00001975- regrtest.py now has a -M option to run tests that test the new limits of
1976 containers, on 64-bit architectures. Running these tests is only sensible
1977 on 64-bit machines with more than two gigabytes of memory. The argument
1978 passed is the maximum amount of memory for the tests to use.
1979
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001980Tools
1981-----
1982
1983- Added the Python benchmark suite pybench to the Tools/ directory;
1984 contributed by Marc-Andre Lemburg.
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001985
Anthony Baxter51bcb682006-04-05 14:51:42 +00001986Documentation
1987-------------
1988
Tim Petersb06d28c2006-05-12 01:57:59 +00001989- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1990
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001991- PEP 343: Added Context Types section to the library reference
1992 and attempted to bring other PEP 343 related documentation into
1993 line with the implementation and/or python-dev discussions.
1994
Tim Peters8dc73d22006-04-24 02:03:16 +00001995- Bug #1337990: clarified that ``doctest`` does not support examples
1996 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001999What's New in Python 2.5 alpha 1?
2000=================================
2001
Anthony Baxterebed3f62006-04-03 15:03:44 +00002002*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002003
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002004Core and builtins
2005-----------------
2006
Nick Coghlan43832302006-04-23 17:04:07 +00002007- PEP 338: -m command line switch now delegates to runpy.run_module
2008 allowing it to support modules in packages and zipfiles
2009
Martin v. Löwisc661b882006-04-20 04:54:23 +00002010- On Windows, .DLL is not an accepted file name extension for
2011 extension modules anymore; extensions are only found if they
2012 end in .PYD.
2013
Martin v. Löwisea62d252006-04-03 10:56:49 +00002014- Bug #1421664: sys.stderr.encoding is now set to the same value as
2015 sys.stdout.encoding.
2016
Neal Norwitz92e212f2006-04-03 04:48:37 +00002017- __import__ accepts keyword arguments.
2018
Georg Brandlccadf842006-03-31 18:54:53 +00002019- Patch #1460496: round() now accepts keyword arguments.
2020
Anthony Baxter262c00a2006-03-30 10:53:17 +00002021- Fixed bug #1459029 - unicode reprs were double-escaped.
2022
Hye-Shik Changd478f342006-03-23 12:32:36 +00002023- Patch #1396919: The system scope threads are reenabled on FreeBSD
2024 5.4 and later versions.
2025
Neal Norwitze98ccf62006-03-23 05:39:47 +00002026- Bug #1115379: Compiling a Unicode string with an encoding declaration
2027 now gives a SyntaxError.
2028
Georg Brandlabd1ff82006-03-18 07:59:59 +00002029- Previously, Python code had no easy way to access the contents of a
2030 cell object. Now, a ``cell_contents`` attribute has been added
2031 (closes patch #1170323).
2032
Tim Peterscf79aac2006-03-16 01:14:46 +00002033- Patch #1123430: Python's small-object allocator now returns an arena to
2034 the system ``free()`` when all memory within an arena becomes unused
2035 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2036 freed. Some applications will see a drop in virtual memory size now,
2037 especially long-running applications that, from time to time, temporarily
2038 use a large number of small objects. Note that when Python returns an
2039 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002040 platform C library will in turn return that memory to the operating system.
2041 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002042 appears to be effective at least on Microsoft C and gcc-based systems.
2043 Thanks to Evan Jones for hard work and patience.
2044
Georg Brandl533ff6f2006-03-08 18:09:27 +00002045- Patch #1434038: property() now uses the getter's docstring if there is
2046 no "doc" argument given. This makes it possible to legitimately use
2047 property() as a decorator to produce a read-only property.
2048
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002049- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2050 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2051 of requiring an int or long in slicing and a few other contexts, enabling
2052 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2053
Neal Norwitz995acdf2006-03-07 05:01:00 +00002054- Fixed various bugs reported by Coverity's Prevent tool.
2055
Brett Cannonbf364092006-03-01 04:25:17 +00002056- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2057 new exception base class, BaseException, which has a new message attribute.
2058 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2059 Raising a string exception now raises a DeprecationWarning.
2060
Thomas Woutersfb609f42006-02-28 16:37:25 +00002061- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2062 explicitly relative, using 'from .module import name' to mean 'from the same
2063 package as this module is in. Imports without dots still default to the
2064 old relative-then-absolute, unless 'from __future__ import
2065 absolute_import' is used.
2066
Brett Cannona7446e32006-02-27 23:39:10 +00002067- Properly check if 'warnings' raises an exception (usually when a filter set
2068 to "error" is triggered) when raising a warning for raising string
2069 exceptions.
2070
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002071- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002072 The name was removed from Include/code.h.
2073
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002074- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002075
Guido van Rossum1968ad32006-02-25 22:38:04 +00002076- Patch 1433928:
2077 - The copy module now "copies" function objects (as atomic objects).
2078 - dict.__getitem__ now looks for a __missing__ hook before raising
2079 KeyError.
2080
Tim Peters84ef21c2006-02-28 20:39:06 +00002081- PEP 343: with statement implemented. Needs ``from __future__ import
2082 with_statement``. Use of 'with' as a variable will generate a warning.
2083 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002084 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002085 The following objects have __context__ methods:
2086 - The built-in file type.
2087 - The thread.LockType type.
2088 - The following types defined by the threading module:
2089 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2090 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002091
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002092- Fix the encodings package codec search function to only search
2093 inside its own package. Fixes problem reported in patch #1433198.
2094
2095 Note: Codec packages should implement and register their own
2096 codec search function. PEP 100 has the details.
2097
Tim Peters9ea89d22006-06-04 03:26:02 +00002098- PEP 353: Using ``Py_ssize_t`` as the index type.
2099
2100- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2101 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2102 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2103 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2104 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002105
Neal Norwitzfc76d632006-01-10 06:03:13 +00002106- Patch #1400181, fix unicode string formatting to not use the locale.
2107 This is how string objects work. u'%f' could use , instead of .
2108 for the decimal point. Now both strings and unicode always use periods.
2109
Neal Norwitz671b9e32006-01-09 07:07:12 +00002110- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2111 configure would break checking curses.h.
2112
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002113- Bug #959576: The pwd module is now builtin. This allows Python to be
2114 built on UNIX platforms without $HOME set.
2115
Neal Norwitzc10978f2005-12-19 06:07:16 +00002116- Bug #1072182, fix some potential problems if characters are signed.
2117
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002118- Bug #889500, fix line number on SyntaxWarning for global declarations.
2119
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002120- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2121
Neal Norwitze7214a12005-12-18 05:03:17 +00002122- Support for converting hex strings to floats no longer works.
2123 This was not portable. float('0x3') now raises a ValueError.
2124
Barry Warsaw2a38a862005-12-18 01:27:35 +00002125- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002126 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002127 is now displayed in interactive prompt banner.
2128
Georg Brandlfa166682005-12-17 21:45:17 +00002129- Implementation of PEP 341 - Unification of try/except and try/finally.
2130 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002131 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002132
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002133- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2134 now encodes backslash correctly.
2135
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002136- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2137
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002138- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002139 and long longs.
2140
Neal Norwitz67715f02005-11-09 06:59:35 +00002141- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002142 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002143 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002144
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002145- Replaced most Unicode charmap codecs with new ones using the
2146 new Unicode translate string feature in the builtin charmap
2147 codec; the codecs were created from the mapping tables available
2148 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2149 encodings now include a mapping for the Apple logo)
2150
Tim Peterse3547fd2005-12-16 23:13:57 +00002151- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002152
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002153- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002154
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002155- A new AST parser implementation was completed. The abstract
2156 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002157 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002158
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002159- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002160 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2161
Neal Norwitz708e51a2005-10-03 04:48:15 +00002162- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2163
Neal Norwitz11bd1192005-10-03 00:54:56 +00002164- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2165 Provide a warning when a directory is passed on the command line.
2166
Neal Norwitz40d37812005-10-02 01:48:49 +00002167- Fix segfault with invalid coding.
2168
2169- SF bug #772896: unknown encoding results in MemoryError.
2170
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002171- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002172 supported a __len__() method which evaluated to False when the iterator
2173 was empty.
2174
Guido van Rossum630db602005-09-20 18:49:54 +00002175- On 64-bit platforms, when __len__() returns a value that cannot be
2176 represented as a C int, raise OverflowError.
2177
Skip Montanarof8948ca2005-09-19 03:54:46 +00002178- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002179 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002180
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002181- SF bug #893549: parsing keyword arguments was broken with a few format
2182 codes.
2183
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002184- Changes donated by Elemental Security to make it work on AIX 5.3
2185 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2186 bug #105470: test_pwd fails on 64bit system (Opteron).
2187
Guido van Rossum539c6622005-09-14 17:49:54 +00002188- Changes donated by Elemental Security to make it work on HP-UX 11 on
2189 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2190
Georg Brandl4550b8d2005-08-26 06:43:52 +00002191- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002192 (fixes bug #1119418).
2193
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002194- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2195
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002196- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2197 exceptions that cause a function to exit.
2198
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002199- The implementation of set() and frozenset() was revised to use its
2200 own internal data structure. Memory consumption is reduced by 1/3
2201 and there are modest speed-ups as well. The API is unchanged.
2202
Tim Petersde7990b2005-07-17 23:45:23 +00002203- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2204
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002205- SF bug #1229429: PyObject_CallMethod failed to decrement some
2206 reference counts in some error exit cases.
2207
Tim Petersecc6e6a2005-07-10 22:30:55 +00002208- SF bug #1185883: Python's small-object memory allocator took over
2209 a block managed by the platform C library whenever a realloc specified
2210 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002211 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002212 portable way to copy data from the C-managed block into Python's
2213 small-object space without risking a memory fault. Python's small-object
2214 realloc now leaves such blocks under the control of the platform C
2215 realloc.
2216
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002217- SF bug #1232517: An overflow error was not detected properly when
2218 attempting to convert a large float to an int in os.utime().
2219
Raymond Hettinger3296e692005-06-29 23:29:56 +00002220- SF bug #1224347: hex longs now print with lowercase letters just
2221 like their int counterparts.
2222
Michael W. Hudson188d4362005-06-20 16:52:57 +00002223- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2224 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2225 interpreter states; back out that fix and do a better job (see
2226 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2227 for a longer write-up of the problem).
2228
Michael W. Hudsondf888462005-06-03 14:41:55 +00002229- SF patch #1180995: marshal now uses a binary format by default when
2230 serializing floats.
2231
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002232- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2233 the routines that promise to produce IEEE 754 binary representations
2234 of floats now simply copy bytes around.
2235
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002236- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2237 278.
2238
Brett Cannonc3647ac2005-04-26 03:45:26 +00002239- patch #1109424: int, long, float, complex, and unicode now check for the
2240 proper magic slot for type conversions when subclassed. Previously the
2241 magic slot was ignored during conversion. Semantics now match the way
2242 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002243 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002244 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002245 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002246
Barry Warsawc8d907c2005-04-19 23:43:40 +00002247- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2248 NULL, now raise an AttributeError when attempting to set or delete the
2249 attribute. Previously a TypeError was raised, but this was inconsistent
2250 with the equivalent pure-Python implementation.
2251
Michael W. Hudson774479c2005-04-18 08:46:17 +00002252- It is now safe to call PyGILState_Release() before
2253 PyEval_InitThreads() (note that if there is reason to believe there
2254 are multiple threads around you still must call PyEval_InitThreads()
2255 before using the Python API; this fix is for extension modules that
2256 have no way of knowing if Python is multi-threaded yet).
2257
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002258- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2259 disabled caused a crash.
2260
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002261- Bug #1165306: instancemethod_new allowed the creation of a method
2262 with im_class == im_self == NULL, which caused a crash when called.
2263
Tim Petersecc6e6a2005-07-10 22:30:55 +00002264- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002265 fixes the crash seen in bug #1165761
2266
Raymond Hettinger96229b12005-03-11 06:49:40 +00002267- Added two new builtins, any() and all().
2268
Brett Cannon409d8f22005-03-05 06:47:57 +00002269- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002270 (e.g., ``class C(): pass`` is no longer a syntax error).
2271 Patch #1176012 added support to the 'parser' module and 'compiler' package
2272 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002273
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002274- Patch #1115086: Support PY_LONGLONG in structmember.
2275
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002276- Bug #1155938: new style classes did not check that __init__() was
2277 returning None.
2278
Tim Petersecc6e6a2005-07-10 22:30:55 +00002279- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002280 ('\') with a specific error message.
2281
Martin v. Löwisff232d72005-03-03 09:24:38 +00002282- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2283
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002284- Bug #1124295: the __name__ attribute of file objects was
2285 inadvertently made inaccessible in restricted mode.
2286
Tim Petersecc6e6a2005-07-10 22:30:55 +00002287- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002288 an ferror() call.
2289
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002290- min() and max() now support key= arguments with the same meaning as in
2291 list.sort().
2292
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002293- The peephole optimizer now performs simple constant folding in expressions:
2294 (2+3) --> (5).
2295
Raymond Hettingera422c342005-01-11 03:03:27 +00002296- set and frozenset objects can now be marshalled. SF #1098985.
2297
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002298- Bug #1077106: Poor argument checking could cause memory corruption
2299 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002300
Jeremy Hyltonab630502005-02-04 18:44:06 +00002301- The parser did not complain about future statements in illegal
2302 positions. It once again reports a syntax error if a future
2303 statement occurs after anything other than a doc string.
2304
Neil Schemenauercf52c072005-08-12 17:34:58 +00002305- Change the %s format specifier for str objects so that it returns a
2306 unicode instance if the argument is not an instance of basestring and
2307 calling __str__ on the argument returns a unicode instance.
2308
Tim Petersf4e69282006-02-27 17:15:31 +00002309- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2310 current thread state when the auto-GIL-state machinery knows about
2311 it (since the thread state is being deleted, continuing to remember it
2312 can't help, but can hurt if another thread happens to get created with
2313 the same thread id).
2314
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002315Extension Modules
2316-----------------
2317
Georg Brandl43f08a82006-03-31 18:01:16 +00002318- Patch #1380952: fix SSL objects timing out on consecutive read()s
2319
Neal Norwitz05a45592006-03-20 06:30:08 +00002320- Patch #1309579: wait3 and wait4 were added to the posix module.
2321
Anthony Baxterfa869072006-03-20 05:21:58 +00002322- Patch #1231053: The audioop module now supports encoding/decoding of alaw.

2446 the request code argument, which results in more C-like behaviour
2447 for large or negative values.

2491
Raymond Hettingerb2594052004-12-05 09:25:51 +00002492- itertools.islice() now accepts None for the start and step arguments.
2493 This allows islice() to work more readily with slices:
2494 islice(s.start, s.stop, s.step)
2495
Skip Montanaro0af3ade2005-01-13 04:12:31 +00002496- datetime.datetime() now has a strptime class method which can be used to

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002505- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2506 been renamed to have only a single underscore prefix. This was done to
2507 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002508
Nick Coghlan43832302006-04-23 17:04:07 +00002509- PEP 338: new module runpy defines a run_module function to support
2510 executing modules which provide access to source code or a code object
2511 via the PEP 302 import mechanisms.
2512
Anthony Baxter93f5b932006-04-03 08:05:07 +00002513- The email module's parsedate_tz function now sets the daylight savings

2521 in attribute values.
2522
Anthony Baxterc51ee692006-04-01 00:57:31 +00002523- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002524 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002525 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002526 module will not be built.
2527
Tim Petersc17976e2006-04-01 00:26:53 +00002528- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2529 aren't officially supported here, and trying to use them will probably
2530 raise an exception some day. But dicts have been allowed, and "mostly
2531 worked", so support for them won't go away without warning.
2532
Georg Brandl338ef7d2006-03-31 18:42:16 +00002533- Bug #1445068: getpass.getpass() can now be given an explicit stream
2534 argument to specify where to write the prompt.
2535

2551
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002552- email 4.0 package now integrated. This is largely the same as the email 3.0
2553 package that was included in Python 2.3, except that PEP 8 module names are
2554 now used (e.g. mail.message instead of email.Message). The MIME classes
2555 have been moved to a subpackage (e.g. email.mime.text instead of
2556 email.MIMEText). The old names are still supported for now. Several
2557 deprecated Message methods have been removed and lots of bugs have been
2558 fixed. More details can be found in the email package documentation.
2559
Walter Dörwald40108c92006-03-27 08:15:44 +00002560- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2561 (a subclass of tuple) that provides incremental decoders and encoders
2562 (a way to use stateful codecs without the stream API). Python functions
2563 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2564 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2565 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00002567- Patch #1359365: Calling next() on a closed StringIO.String object raises
2568 a ValueError instead of a StopIteration now (like file and cString.String do).
2569 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2570 called before (like file and StringIO.StringIO do).

2646 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2647 Ronald L. Rivest offered this advice for Python:
2648
2649 "The consensus of researchers in this area (at least as
2650 expressed at the NIST Hash Function Workshop 10/31/05),
2651 is that SHA-256 is a good choice for the time being, but
2652 that research should continue, and other alternatives may
2653 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002654

2835 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002836 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002837 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002838 + Dialect parameter parsing has been re-implemented to improve error

2840 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2841 dictates.
2842 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002843 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002844 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002845 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2846 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002847 + reader now allows \r characters to be quoted (previously it only allowed
2848 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002849 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002850 + Dialect classes passed to the module are no longer instantiated by
2851 the module before being parsed (the former validation scheme required
2852 this, but the mechanism was unreliable).
2853 + The dialect registry now contains instances of the internal
2854 C-coded dialect type, rather than references to python objects.
2855 + the internal c-coded dialect type is now immutable.
2856 + register_dialect now accepts the same keyword dialect specifications
2857 as the reader and writer, allowing the user to register dialects
2858 without first creating a dialect class.
2859 + a configurable limit to the size of parsed fields has been added -
2860 previously, an unmatched quote character could result in the entire
2861 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002862 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002863 the parser field size limit (returning the former limit). The initial
2864 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002865 + A line_num attribute has been added to the reader object, which tracks
2866 the number of lines read from the source iterator. This is not
2867 the same as the number of records returned, as records can span
2868 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002869 + reader and writer objects were not being registered with the cyclic-GC.
2870 This has been fixed.
2871
Brett Cannone6539c42005-01-08 02:43:53 +00002872- _DummyThread objects in the threading module now delete self.__block that is
2873 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2874 lock primitives tend to be limited in number and thus should not be wasted on
2875 a _DummyThread object. Fixes bug #1089632.
2876
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002877- The imghdr module now detects Exif files.
2878
Raymond Hettinger6065d322004-12-20 23:51:53 +00002879- StringIO.truncate() now correctly adjusts the size attribute.
2880 (Bug #951915).
2881
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002882- locale.py now uses an updated locale alias table (built using
2883 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2884 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002885 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002886
Raymond Hettinger3557f422004-12-07 12:02:02 +00002887- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2888
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002889- the pickle module no longer accepts the deprecated None option in the
2890 args tuple returned by __reduce__().
2891
Brett Cannon84667c02004-12-07 03:25:18 +00002892- optparse now optionally imports gettext. This allows its use in setup.py.
2893
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002894- the pickle module no longer uses the deprecated bin parameter.
2895
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002896- the shelve module no longer uses the deprecated binary parameter.
2897
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002898- the pstats module no longer uses the deprecated ignore() method.
2899
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002900- the filecmp module no longer uses the deprecated use_statcache argument.
2901
Raymond Hettinger664347b2004-12-04 21:21:53 +00002902- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2903 extended or overridden by subclasses. Formerly, the subclassed method would
2904 be ignored by the rest of the module. (Bug #1078905).
2905
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002906- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002907 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002908
Walter Dörwald36733692004-12-22 12:50:50 +00002909- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2910 once when a size argument is given. This prevents a buffer overflow in the
2911 tokenizer with very long source lines.
2912
Barry Warsaw538561e2006-01-01 21:48:54 +00002913- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2914 immediately after creating the object, without any intervening
2915 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002916
Skip Montanaro05885812005-01-16 20:48:27 +00002917- The reconvert.quote function can now emit triple-quoted strings. The
2918 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002919
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002920- ``UserString.MutableString`` now supports negative indices in
2921 ``__setitem__`` and ``__delitem__``
2922
Greg Ward40407942005-03-05 02:53:17 +00002923- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2924 correctly.
2925
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002926- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2927 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2928 character even if the user has passed a size parameter to get a proper
2929 line ending. Remove the special handling of a "\r\n" that has been split
2930 between two lines.
2931
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002932- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2933 about illegal code points. The codec now supports PEP 293 style error
2934 handlers.
2935
Walter Dörwald78a78b02005-09-01 12:04:29 +00002936- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002937 from the input stream, so that the output is a byte string in the correct
2938 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002939
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002940- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2941 considering it exactly like a '*'.
2942
Walter Dörwald007f8df2005-10-09 19:42:27 +00002943- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2944 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002945
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002946- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2947
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002948- Patch #1413711: Certain patterns of differences were making difflib
2949 touch the recursion limit.
2950
Walter Dörwald58917a62006-03-31 15:26:22 +00002951- Bug #947906: An object oriented interface has been added to the calendar
2952 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002953 called as a script (e.g. via ``python -mcalendar``). Localized month and
2954 weekday names can be ouput (even if an exotic encoding is used) using
2955 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002956
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002957Build
2958-----
2959
Neal Norwitz602d3392006-03-31 08:21:40 +00002960- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2961 by using -mieee gcc option.
2962
Martin v. Löwis86d66262006-02-17 08:40:11 +00002963- Patch #1432345: Make python compile on DragonFly.
2964
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002965- Build support for Win64-AMD64 was added.
2966
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002967- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2968
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002969- Patch #881820: look for openpty and forkpty also in libbsd.
2970
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002971- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2972 The zlib module is now builtin on Windows.
2973
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002974- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2975
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002976- Bug #1189330: configure did not correctly determine the necessary
2977 value of LINKCC if python was built with GCC 4.0.
2978
Trent Mick8321b422005-07-26 02:29:21 +00002979- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2980 vulnerability in zlib 1.2.1 and 1.2.2.
2981
Brett Cannon08cd5982005-04-24 22:26:38 +00002982- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2983 flags that change binary compatibility. Changes were also made to
2984 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002985 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002986
Bob Ippolitoed233462005-03-29 13:47:59 +00002987- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2988 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2989 no longer exists). This configure patch makes things right.
2990
Martin v. Löwise2713be2005-03-08 15:03:08 +00002991- Bug #1158607: Build with --disable-unicode again.
2992
Brett Cannon46d96232005-02-16 00:07:19 +00002993- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2994 defined. Discovered as a result of not being able to build on OS X.
2995
Brett Cannon516592f2004-12-07 00:42:59 +00002996- setup.py now uses the directories specified in LDFLAGS using the -L option
2997 and in CPPFLAGS using the -I option for adding library and include
2998 directories, respectively, for compiling extension modules against. This has
2999 led to the core being compiled using the values in CPPFLAGS. It also removes
3000 the need for the special-casing of both DarwinPorts and Fink for darwin since
3001 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3002 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3003 Fink, ``-I/opt/local/include`` for DarwinPorts).
3004
Brett Cannon43802422005-02-10 20:48:03 +00003005- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3006 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3007 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3008 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003010C API
3011-----
3012
Tim Petersc9d78aa2006-03-26 23:27:58 +00003013- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3014 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3015 is obtained via the ``PyObject_`` family, it must be released via the
3016 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3017 always been officially true, but when Python's small-object allocator was
3018 introduced, an attempt was made to cater to a few extension modules
3019 discovered at the time that obtained memory via ``PyObject_New`` but
3020 released it via ``PyMem_DEL``. It's years later, and if such code still
3021 exists it will fail now (probably with segfaults, but calling wrong
3022 low-level memory management functions can yield many symptoms).
3023
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003024- Added a C API for set and frozenset objects.
3025
Raymond Hettinger66517482004-12-03 11:45:13 +00003026- Removed PyRange_New().
3027
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003028- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3029 mapping argument now. This string is used as a mapping table. Byte values
3030 greater than the length of the string and 0xFFFE are treated as undefined
3031 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003038
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00003039- Patch #1276356: New resource "urlfetch" is implemented. This enables
