Neal Norwitz0ac60192007-05-27 04:08:54 +000033- Add new attribute names for function objects. All the func_* become
34 __*__ attributes. (Some already existed, e.g., __doc__ and __name__.)
35
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +000036- Add -3 option to the interpreter to warn about features that are
37 deprecated and will be changed/removed in Python 3.0.
38
Georg Brandl2134e752007-05-21 20:34:16 +000039- Patch #1686487: you can now pass any mapping after '**' in function
40 calls.
41
Collin Winter62903052007-05-18 23:11:24 +000042- except clauses may now be spelled either "except E, target:" or
43 "except E as target:". This is to provide forwards compatibility with
44 Python 3.0.
45
Brett Cannon229cee22007-05-05 01:34:02 +000046- Deprecate BaseException.message as per PEP 352.
47

49 inherited from a builtin base.
50
Vinay Sajip8549ce32007-05-06 17:53:37 +000051- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +000052 setting a plain string, ie don't expand to single letter identifiers.
53
Raymond Hettinger13936692007-04-11 18:40:58 +000054- Request #1191699: Slices can now be pickled.
55
Raymond Hettinger4db5fe92007-04-12 04:10:00 +000056- Request #1193128: str.translate() now allows a None argument for
57 translations that only remove characters without re-mapping the
58 remaining characters.
59
Georg Brandl5cb76c12007-03-21 09:00:39 +000060- Patch #1682205: a TypeError while unpacking an iterable is no longer
61 masked by a generic one with the message "unpack non-sequence".
62
Neal Norwitzaa754b72007-03-21 06:39:48 +000063- Remove unused file Python/fmod.c.
64
Guido van Rossum143b5642007-03-23 04:58:42 +000065- Bug #1683368: The object.__init__() and object.__new__() methods are
66 now stricter in rejecting excess arguments. The only time when
67 either allows excess arguments is when it is not overridden and the
68 other one is. For backwards compatibility, when both are
69 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +000070 warning later). Also, type.__init__() insists on the same signature
71 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +000072
Georg Brandl2b869942007-03-17 16:08:45 +000073- Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
74 to complex using its __complex__() method before falling back to the
75 __float__() method. Therefore, the functions in the cmath module now
76 can operate on objects that define a __complex__() method.
77
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +000078- Patch #1623563: allow __class__ assignment for classes with __slots__.
79 The old and the new class are still required to have the same slot names.
80
Collin Winter77c67bd2007-03-16 04:11:30 +000081- Patch #1642547: Fix an error/crash when encountering syntax errors in
82 complex if statements.
83
Žiga Seilnacht20f43d32007-03-15 11:44:55 +000084- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
85 is called with an object that is faking its type.
86
Žiga Seilnacht71436f02007-03-14 12:24:09 +000087- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
88 name.
89
Georg Brandl5240d742007-03-13 20:46:32 +000090- Patch #1444529: the builtin compile() now accepts keyword arguments.
91
Georg Brandl7b9c5552007-03-12 14:30:05 +000092- Bug #1678647: write a newline after printing an exception in any
93 case, even when converting the value to a string failed.
94
Georg Brandl871f1bc2007-03-12 13:17:36 +000095- The dir() function has been extended to call the __dir__() method on
96 its argument, if it exists. If not, it will work like before. This allows
97 customizing the output of dir() in the presence of a __getattr__().
98
Collin Winter276887b2007-03-12 16:11:39 +000099- Patch #922167: Python no longer segfaults when faced with infinitely
100 self-recursive reload() calls (as reported by bug #742342).
101
Žiga Seilnacht89032082007-03-11 15:54:54 +0000102- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
103
Collin Wintere38051d2007-03-09 20:33:07 +0000104- Patch #1491866: change the complex() constructor to allow parthensized
105 forms. This means complex(repr(x)) now works instead of raising a
106 ValueError.
107
Georg Brandlaa2321b2007-03-07 00:40:28 +0000108- Patch #703779: unset __file__ in __main__ after running a file. This
109 makes the filenames the warning module prints much more sensible when
110 a PYTHONSTARTUP file is used.
111
Georg Brandl49aafc92007-03-07 00:34:46 +0000112- Variant of patch #697613: don't exit the interpreter on a SystemExit
113 exception if the -i command line option or PYTHONINSPECT environment
114 variable is given, but break into the interactive interpreter just like
115 on other exceptions or normal program exit.
116
Georg Brandl00cd8182007-03-06 18:41:12 +0000117- Patch #1638879: don't accept strings with embedded NUL bytes in long().
118
Georg Brandl098cd692007-03-06 12:17:50 +0000119- Bug #1674503: close the file opened by execfile() in an error condition.
120
Georg Brandl0fca97a2007-03-05 22:28:08 +0000121- Patch #1674228: when assigning a slice (old-style), check for the
122 sq_ass_slice instead of the sq_slice slot.
123
Neal Norwitz88516a62007-02-26 22:41:45 +0000124- When printing an unraisable error, don't print exceptions. before the name.
125 This duplicates the behavior whening normally printing exceptions.
126
Martin v. Löwisfd963262007-02-09 12:19:32 +0000127- Bug #1653736: Properly discard third argument to slot_nb_inplace_power.
128
Brett Cannon129bd522007-01-30 21:34:36 +0000129- PEP 352: Raising a string exception now triggers a TypeError. Attempting to
130 catch a string exception raises DeprecationWarning.
131
Brett Cannonf5bee302007-01-23 23:21:22 +0000132- Bug #1377858: Fix the segfaulting of the interpreter when an object created
133 a weakref on itself during a __del__ call for new-style classes (classic
134 classes still have the bug).
135
Martin v. Löwis6c5c5022007-01-23 21:11:47 +0000136- Bug #1579370: Make PyTraceBack_Here use the current thread, not the

170
Neal Norwitzcbeb6872006-10-14 21:33:38 +0000171- Update the peephole optimizer to remove more dead code (jumps after returns)
172 and inline unconditional jumps to returns.
173
Georg Brandl2c1375c2006-10-12 11:27:59 +0000174- Bug #1545497: when given an explicit base, int() did ignore NULs
175 embedded in the string to convert.
176
Georg Brandl846f73a2006-10-08 07:11:54 +0000177- Bug #1569998: break inside a try statement (outside a loop) is now
178 recognized and rejected.
179
Armin Rigo7ccbca92006-10-04 12:17:45 +0000180- list.pop(x) accepts any object x following the __index__ protocol.
181
182- Fix some leftovers from the conversion from int to Py_ssize_t
183 (relevant to strings and sequences of more than 2**31 items).
184
185- A number of places, including integer negation and absolute value,
186 were fixed to not rely on undefined behaviour of the C compiler
187 anymore.

205
Brett Cannon9adeab72006-09-20 18:34:28 +0000206- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This

Facundo Batista70f996b2007-05-21 17:32:32 +0000336 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +0000337

Collin Winterfaaa2042007-03-10 03:35:34 +0000425 be equal to calling getsockname() on the server's socket. Fixed by

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

479 import semantics.

Georg Brandldb846032007-03-31 18:56:11 +0000931- Bug #1655392: don't add -L/usr/lib/pythonX.Y/config to the LDFLAGS
932 returned by python-config if Python was built with --enable-shared
933 because that prevented the shared library from being used.
934
Georg Brandl18c47f62007-03-13 10:19:22 +0000935- Patch #1569798: fix a bug in distutils when building Python from a

993
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000994- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000995 compared equal or unequal to a string and a UnicodeDecodeError
996 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000997
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000998 Instead, the equal (==) and unequal (!=) comparison operators will
999 now issue a UnicodeWarning and interpret the two objects as
1000 unequal. The UnicodeWarning can be filtered as desired using
1001 the warning framework, e.g. silenced completely, turned into an
1002 exception, logged, etc.
1003
1004 Note that compare operators other than equal and unequal will still
1005 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001006
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001007- Fix segfault when doing string formatting on subclasses of long.
1008
1009- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1010 with new-style classes.
1011
1012- Fix bug related to __len__ functions returning negative values with
1013 classic classes.
1014
1015- Patch #1538606, Fix __index__() clipping. There were some problems
1016 discovered with the API and how integers that didn't fit into Py_ssize_t
1017 were handled. This patch attempts to provide enough alternatives
1018 to effectively use __index__.
1019
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001020- Bug #1536021: __hash__ may now return long int; the final hash
1021 value is obtained by invoking hash on the long int.
1022
Thomas Hellerab1049c2006-08-08 17:37:00 +00001023- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1024
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001025- Bug #1535165: fixed a segfault in input() and raw_input() when
1026 sys.stdin is closed.
1027
Thomas Heller74d36f02006-08-04 18:17:40 +00001028- On Windows, the PyErr_Warn function is now exported from
1029 the Python dll again.
1030
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001031- Bug #1191458: tracing over for loops now produces a line event
1032 on each iteration. Fixing this problem required changing the .pyc
1033 magic number. This means that .pyc files generated before 2.5c1
1034 will be regenerated.
1035
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001036- Bug #1333982: string/number constants were inappropriately stored
1037 in the byte code and co_consts even if they were not used, ie
1038 immediately popped off the stack.
1039
Georg Brandle9462c72006-08-04 18:03:37 +00001040- Fixed a reference-counting problem in property().

1043Library
1044-------
1045
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001046- Fix a bug in the ``compiler`` package that caused invalid code to be
1047 generated for generator expressions.
1048
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001049- The distutils version has been changed to 2.5.0. The change to
1050 keep it programmatically in sync with the Python version running
1051 the code (introduced in 2.5b3) has been reverted. It will continue
1052 to be maintained manually as static string literal.
1053
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001054- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001055 and this cannot be converted to the required C type, an exception is
1056 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001057 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001058
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001059- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001060 an exception.
1061
Tim Petersc10c9d02006-09-05 02:18:09 +00001062- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001063 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001064 workarounds for clocks with low resolution, to stop the code yielding
1065 duplicate UUIDs.
1066
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001067- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1068 before raising SystemExit, allowing IDLE to honor quit() and exit().
1069
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001070- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1071
Georg Brandl7a1af772006-08-14 21:55:28 +00001072- Patch #1536071: trace.py should now find the full module name of a
1073 file correctly even on Windows.
1074
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001075- logging's atexit hook now runs even if the rest of the module has
1076 already been cleaned up.
1077
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001078- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001079
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001080- Bug #1531405, format_exception no longer raises an exception if
1081 str(exception) raised an exception.
1082
Neil Schemenauer06ded092006-08-04 16:20:30 +00001083- Fix a bug in the ``compiler`` package that caused invalid code to be
1084 generated for nested functions.

Georg Brandl3335a7a2006-08-14 21:42:55 +00001092- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
1093 raises the correct exceptions.
1094
Thomas Heller1ce433e2006-08-14 16:20:04 +00001095- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1096 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1097
Thomas Heller86720042006-08-14 11:17:48 +00001098- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1099 uses the _as_parameter_ attribute when objects are passed to foreign
1100 function calls. The ctypes version number was changed to 1.0.1.
1101
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001102- Bug #1530559, struct.pack raises TypeError where it used to convert.
1103 Passing float arguments to struct.pack when integers are expected
1104 now triggers a DeprecationWarning.

1155-----------------
1156
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001157- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001158 returned a long (see PEP 353).
1159
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001160- Bug #1515471: string.replace() accepts character buffers again.
1161
Neal Norwitz07aadb12006-07-30 06:55:48 +00001162- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1163 This provides the proper warning for struct.pack().
1164 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1165
Neal Norwitz0d62a062006-07-30 06:53:31 +00001166- Patch #1531113: Fix augmented assignment with yield expressions.
1167 Also fix a SystemError when trying to assign to yield expressions.
1168
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001169- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1170 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1171 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1172 excessive filesystem operations during imports.
1173
Tim Petersbc24eee2006-07-27 01:14:53 +00001174- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1175 operations on signed longs that are formally undefined by C.
1176 Unfortunately, at least one compiler now cares about that, so complicated
1177 the code to make that compiler happy again.
1178
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001179- Bug #1524310: Properly report errors from FindNextFile in os.listdir.

Martin v. Löwisd22968a2006-07-24 11:54:53 +00001181- Patch #1232023: Stop including current directory in search
1182 path on Windows.
1183
Neal Norwitze1fdb322006-07-21 05:32:28 +00001184- Fix some potential crashes found with failmalloc.

1187
Neal Norwitz84be93b2006-07-16 01:50:38 +00001188- Bug #1512814, Fix incorrect lineno's when code within a function
1189 had more than 255 blank lines.
1190
Georg Brandl9dceedb2006-07-12 15:31:17 +00001191- Patch #1521179: Python now accepts the standard options ``--help`` and
1192 ``--version`` as well as ``/?`` on Windows.
1193
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001194- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001195 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001196 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001197
Tim Peters112aad32006-07-19 00:03:19 +00001198- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001199 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001200 new ``sys._current_frames()`` returns a dictionary with one entry,
1201 mapping the faux "thread id" 0 to the current frame.
1202
Ronald Oussoren3075e162006-07-25 20:28:55 +00001203- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

1207-------
1208
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001209- Correction of patch #1455898: In the mbcs decoder, set final=False
1210 for stream decoder, but final=True for the decode function.
1211
Georg Brandl07fec3a2006-08-01 18:49:24 +00001212- os.urandom no longer masks unrelated exceptions like SystemExit or
1213 KeyboardInterrupt.
1214
Tim Peters4643c2f2006-08-10 22:45:34 +00001215- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001216 shutil.copytree on Windows
1217
Georg Brandle34ac7c2006-07-30 11:07:23 +00001218- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1219 refers to file descriptors, not file objects.
1220
Tim Petersc10c9d02006-09-05 02:18:09 +00001221- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001222 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001223 #1513611, and probably others.
1224
Georg Brandledd9b0d2006-07-29 09:33:26 +00001225- Bug #1441397: The compiler module now recognizes module and function
1226 docstrings correctly as it did in Python 2.4.
1227
Tim Peters6f681472006-07-27 23:44:37 +00001228- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1229 lost that tests are sorted by name before being run. This rarely
1230 matters for well-written tests, but can create baffling symptoms if
1231 side effects from one test to the next affect outcomes. ``DocTestFinder``
1232 has been changed to sort the list of tests it returns.
1233
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001234- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001235 in sync with sys.version_info[:3].

Martin v. Löwis9298eff2006-07-26 12:12:56 +00001237- Bug #978833: Really close underlying socket in _socketobject.close.
1238
Georg Brandl8c036cc2006-08-20 13:15:39 +00001239- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1240 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001241
Georg Brandlcf0c1722006-07-26 07:23:32 +00001242- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1243 to recursive calls and call it with the failing package name.
1244
Martin v. Löwis0b483032006-07-25 09:53:12 +00001245- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1246
Georg Brandlc13c34c2006-07-24 14:09:56 +00001247- Patch #1515343: Fix printing of deprecated string exceptions with a
1248 value in the traceback module.
1249
Greg Ward48fae7a2006-07-23 16:05:51 +00001250- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1251
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001252- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1253
Brett Cannoncaebe222006-07-18 04:41:36 +00001254- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1255 argument tuple. For arguments where zero is illegal, the value is forced to
1256 the minimum value that is correct. This is to support an undocumented but
1257 common way people used to fill in inconsequential information in the time
1258 tuple pre-2.4.
1259
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001260- Patch #1220874: Update the binhex module for Mach-O.
1261
Barry Warsawb110bad2006-07-21 14:51:07 +00001262- The email package has improved RFC 2231 support, specifically for
1263 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1264 (name*0=<blah>) parameter continuations. This may change the types of
1265 values returned from email.message.Message.get_param() and friends.
1266 Specifically in some cases where non-encoded continuations were used,
1267 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1268 will just return the string (since non-encoded continuations don't have
1269 charset and language parts).
1270
1271 Also, whereas % values were decoded in all parameter continuations, they are
1272 now only decoded in encoded parameter parts.
1273
Ronald Oussoren3075e162006-07-25 20:28:55 +00001274- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1275
1276- Bug #1517996: IDLE now longer shows the default Tk menu when a
1277 path browser, class browser or debugger is the frontmost window on MacOS X
1278
Barry Warsaw00decd72006-07-27 23:43:15 +00001279- Patch #1520294: Support for getset and member descriptors in types.py,
1280 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1281 of an object against these built-in types and more importantly, for getting
1282 their docstrings printed in the interactive interpreter's help() function.

1286-----------------
1287
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001288- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1289 a socket operation on a socket with a timeout, the exception will be
1290 caught correctly. Previously, the exception was not caught.
1291
Thomas Heller1393d6a2006-07-28 21:43:20 +00001292- Patch #1529514: The _ctypes extension is now compiled on more
1293 openbsd target platforms.
1294
Tim Peters9cab5932006-07-28 00:30:00 +00001295- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1296 a memory leak, affecting pickles and deep copies.
1297
Tim Petersbc24eee2006-07-27 01:14:53 +00001298- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1300
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001301- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1302
Thomas Hellerce049a02006-07-14 17:51:14 +00001303- Patch #1521817: Index range checking on ctypes arrays containing
1304 exactly one element enabled again. This allows iterating over these
1305 arrays, without the need to check the array size before.
1306
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001307- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001308 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001309 /dev/null in certain cases; this is now fixed.
1310
Thomas Heller47d7a062006-07-12 08:43:47 +00001311- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1312 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001313
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001314- Because of a misspelled preprocessor symbol, ctypes was always
1315 compiled without thread support; this is now fixed.
1316
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001317- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1318 methods now allow their database parameter to be None as the
1319 sleepycat API allows.
1320
Matt Flemingec926502006-07-28 11:27:27 +00001321- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1322 bluetooth API compared with Linux and FreeBSD.
1323
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001324Tests
1325-----
1326
1327- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1328 how long the test file should take to play. Now accepts taking 2.93 secs
1329 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1330
Georg Brandl4793aa32006-07-28 18:31:39 +00001331- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1332 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1333 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001340Mac
1341---
1342
1343- PythonLauncher now works correctly when the path to the script contains
1344 characters that are treated specially by the shell (such as quotes).
1345
1346- Bug #1527397: PythonLauncher now launches scripts with the working directory
1347 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001348 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001349 expect.

1358-----------------
1359
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001360- Bug #1441486: The literal representation of -(sys.maxint - 1)
1361 again evaluates to a int object, not a long.
1362
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001363- Bug #1501934: The scope of global variables that are locally assigned
1364 using augmented assignment is now correctly determined.
1365
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001366- Bug #927248: Recursive method-wrapper objects can now safely
1367 be released.
1368
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001369- Bug #1417699: Reject locale-specific decimal point in float()
1370 and atof().
1371
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001372- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1373 omit a default "error" argument for NULL pointer. This allows
1374 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001375
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001376- Bug #1519018: 'as' is now validated properly in import statements.
1377
Neal Norwitz28746ab2006-07-09 22:14:42 +00001378- On 64 bit systems, int literals that use less than 64 bits are
1379 now ints rather than longs.
1380
Neal Norwitzed657552006-07-10 00:04:44 +00001381- Bug #1512814, Fix incorrect lineno's when code at module scope
1382 started after line 256.
1383
Tim Peters32a83612006-07-10 21:08:24 +00001384- New function ``sys._current_frames()`` returns a dict mapping thread
1385 id to topmost thread stack frame. This is for expert use, and is
1386 especially useful for debugging application deadlocks. The functionality
1387 was previously available in Fazal Majid's ``threadframe`` extension
1388 module, but it wasn't possible to do this in a wholly threadsafe way from
1389 an extension.

1398
Tim Peters32a83612006-07-10 21:08:24 +00001399- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001400 environment variable to be set in order to the SDK environment
1401 for finding the compiler, include files, etc.

Nick Coghlan2d792252006-07-06 13:47:18 +00001405- warnings.py now ignores ImportWarning by default
1406
Thomas Woutersadd19112006-07-05 11:03:49 +00001407- string.Template() now correctly handles tuple-values. Previously,
1408 multi-value tuples would raise an exception and single-value tuples would
1409 be treated as the value they contain, instead.
1410
Martin v. Löwisede77f52006-07-03 13:01:35 +00001411- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1412 even if some data are received.
1413
Martin v. Löwis45482392006-07-03 12:28:58 +00001414- Bug #1267547: Put proper recursive setup.py call into the
1415 spec file generated by bdist_rpm.
1416
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001417- Bug #1514693: Update turtle's heading when switching between
1418 degrees and radians.
1419
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001420- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001421 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001422
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001423- Bug #1514703: Only setup canvas window in turtle when the canvas
1424 is created.
1425
Martin v. Löwis7596e832006-07-01 15:33:37 +00001426- Bug #1513223: .close() of a _socketobj now releases the underlying
1427 socket again, which then gets closed as it becomes unreferenced.
1428
Fred Drake10497c82006-06-29 02:57:48 +00001429- Bug #1504333: Make sgmllib support angle brackets in quoted
1430 attribute values.
1431
1432- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1433 sgmllib ('[' and ']' were not accepted).
1434
Georg Brandl1be63af2006-06-28 20:23:25 +00001435- Fix a bug in the turtle module's end_fill function.
1436
Brett Cannon53ab5b72006-06-22 16:49:14 +00001437- Bug #1510580: The 'warnings' module improperly required that a Warning
1438 category be either a types.ClassType and a subclass of Warning. The proper
1439 check is just that it is a subclass with Warning as the documentation states.
1440
Georg Brandlad29e632006-06-21 17:45:17 +00001441- The compiler module now correctly compiles the new try-except-finally
1442 statement (bug #1509132).
1443
Neal Norwitz60373cd2006-06-22 06:30:50 +00001444- The wsgiref package is now installed properly on Unix.
1445
Vinay Sajip28e57612006-07-01 10:45:20 +00001446- A bug was fixed in logging.config.fileConfig() which caused a crash on
1447 shutdown when fileConfig() was called multiple times.
1448
Gerhard Häring762fbd32006-07-02 17:48:30 +00001449- The sqlite3 module did cut off data from the SQLite database at the first
1450 null character before sending it to a custom converter. This has been fixed
1451 now.

Tim Peters112aad32006-07-19 00:03:19 +00001456- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1457 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1458 The patch makes sockets use poll() internally where available.

Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001460- Assigning None to pointer type fields in ctypes structures possible
1461 overwrote the wrong fields, this is fixed now.
1462
1463- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1464 on non-Windows platforms.
1465
1466- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1467 integer or long, without range checking.
1468
1469- Patch #1517790: It is now possible to use custom objects in the ctypes
1470 foreign function argtypes sequence as long as they provide a from_param
1471 method, no longer is it required that the object is a ctypes type.
1472
1473- The '_ctypes' extension module now works when Python is configured
1474 with the --without-threads option.
1475
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001476- Bug #1513646: os.access on Windows now correctly determines write
1477 access, again.
1478
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001479- Bug #1512695: cPickle.loads could crash if it was interrupted with
1480 a KeyboardInterrupt.
1481
Neal Norwitza12aa882006-07-06 06:45:08 +00001482- Bug #1296433: parsing XML with a non-default encoding and
1483 a CharacterDataHandler could crash the interpreter in pyexpat.
1484
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001485- Patch #1516912: improve Modules support for OpenVMS.

1488-----
1489
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001490- Automate Windows build process for the Win64 SSL module.
1491
Tim Peters32a83612006-07-10 21:08:24 +00001492- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001493 Previously, the slight difference could cause compilation errors of the
1494 'zlib' module on systems with more than one version of zlib.
1495
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001496- The MSI compileall step was fixed to also support a TARGETDIR
1497 with spaces in it.
1498
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001499- Bug #1517388: sqlite3.dll is now installed on Windows independent
1500 of Tcl/Tk.
1501
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001502- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001503 trying to be installed even though it's empty.

1506-----
1507
1508- Call os.waitpid() at the end of tests that spawn child processes in order
1509 to minimize resources (zombies).
1510
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001511Documentation
1512-------------
1513
Nick Coghlan2d792252006-07-06 13:47:18 +00001514- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1515 documentation for the warnings module.
1516
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001517- Patch #1509163: MS Toolkit Compiler no longer available.
1518
Neal Norwitz56640df2006-07-10 02:36:41 +00001519- Patch #1504046: Add documentation for xml.etree.

Nick Coghlanc649ec52006-05-29 12:43:05 +00001522What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +00001523================================
Anthony Baxter51bcb682006-04-05 14:51:42 +00001524
Anthony Baxterd1136802006-06-19 12:04:15 +00001525*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +00001526
1527Core and builtins
1528-----------------
1529
Georg Brandla56b9152006-06-19 06:35:54 +00001530- Patch #1507676: Error messages returned by invalid abstract object operations
1531 (such as iterating over an integer) have been improved and now include the
1532 type of the offending object to help with debugging.
1533
Brett Cannonea3912b2006-06-13 21:46:41 +00001534- Bug #992017: A classic class that defined a __coerce__() method that returned
1535 its arguments swapped would infinitely recurse and segfault the interpreter.
1536
Neal Norwitz909eb122006-06-12 02:13:21 +00001537- Fix the socket tests so they can be run concurrently.
1538
Neal Norwitzb9845e72006-06-12 02:11:18 +00001539- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001540 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001541
Brett Cannon22565aa2006-06-09 22:31:23 +00001542- Bug #532646: object.__call__() will continue looking for the __call__
1543 attribute on objects until one without one is found. This leads to recursion
1544 when you take a class and set its __call__ attribute to an instance of the
1545 class. Originally fixed for classic classes, but this fix is for new-style.
1546 Removes the infinite_rec_3 crasher.
1547
Georg Brandl24250812006-06-09 18:45:48 +00001548- The string and unicode methods startswith() and endswith() now accept
1549 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1550
Brett Cannonde3b0522006-06-08 17:00:45 +00001551- Buffer objects, at the C level, never used the char buffer
1552 implementation even when the char buffer for the wrapped object was
1553 explicitly requested (originally returned the read or write buffer).
1554 Now a TypeError is raised if the char buffer is not present but is
1555 requested.
1556
Georg Brandlddbaa662006-06-04 21:56:52 +00001557- Patch #1346214: Statements like "if 0: suite" are now again optimized
1558 away like they were in Python 2.4.
1559
Georg Brandlb7c8f542006-05-27 12:30:25 +00001560- Builtin exceptions are now full-blown new-style classes instead of
1561 instances pretending to be classes, which speeds up exception handling
1562 by about 80% in comparison to 2.5a2.
1563
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001564- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1565 Unicode 4.1.
1566
Georg Brandlf4ef1162006-05-26 18:03:31 +00001567- Patch #921466: sys.path_importer_cache is now used to cache valid and
1568 invalid file paths for the built-in import machinery which leads to
1569 fewer open calls on startup.
1570
Tim Peters696cf432006-05-24 21:10:40 +00001571- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1572 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1573 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1574 the number of input digits (it was and remains linear-time for bases
1575 2, 4, 8, 16 and 32).
1576
Tim Petersb713ec22006-05-23 18:45:30 +00001577- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1578 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1579 an integer close to ``sys.maxint``. This was repaired by patch
1580 #1335972, which also gives a nice speedup.
1581
Richard Jonescebbefc2006-05-23 18:28:17 +00001582- Patch #1337051: reduced size of frame objects.
1583
1584- PyErr_NewException now accepts a tuple of base classes as its
1585 "base" parameter.
1586
Richard Jones7c88dcc2006-05-23 10:37:38 +00001587- Patch #876206: function call speedup by retaining allocated frame
1588 objects.
1589
Georg Brandl7b90e162006-05-18 07:01:27 +00001590- Bug #1462152: file() now checks more thoroughly for invalid mode
1591 strings and removes a possible "U" before passing the mode to the
1592 C library function.
1593
Neal Norwitz1004a532006-05-15 07:17:23 +00001594- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1595
Neal Norwitz373f0a72006-05-15 07:04:36 +00001596- Bug #1487966: Fix SystemError with conditional expression in assignment
1597
Martin v. Löwis879768d2006-05-11 13:28:43 +00001598- WindowsError now has two error code attributes: errno, which carries
1599 the error values from errno.h, and winerror, which carries the error
1600 values from winerror.h. Previous versions put the winerror.h values
1601 (from GetLastError()) into the errno attribute.
1602
Martin v. Löwis77736712006-05-04 05:51:03 +00001603- Patch #1475845: Raise IndentationError for unexpected indent.
1604
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001605- Patch #1479181: split open() and file() from being aliases for each other.
1606
Tim Peters44bd9862006-06-01 13:49:23 +00001607- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1608 methods were always silently ignored by dictionaries when comparing keys.
1609 They are now passed through (except when using the C API function
1610 ``PyDict_GetItem()``, whose semantics did not change).
1611
1612- Bug #1456209: In some obscure cases it was possible for a class with a
1613 custom ``__eq__()`` method to confuse dict internals when class instances
1614 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1615 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001617Extension Modules
1618-----------------
1619
Trent Mick960a3f82006-06-28 20:30:41 +00001620- Bug #1295808: expat symbols should be namespaced in pyexpat
1621
1622- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1623
Brett Cannon6ee7d012006-06-08 16:23:04 +00001624- Change binascii.hexlify to accept a read-only buffer instead of only a char
1625 buffer and actually follow its documentation.
1626
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001627- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1628
Nick Coghlanc649ec52006-05-29 12:43:05 +00001629- Patch #1478788 (modified version): The functional extension module has
1630 been renamed to _functools and a functools Python wrapper module added.
1631 This provides a home for additional function related utilities that are
1632 not specifically about functional programming. See PEP 309.
1633
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001634- Patch #1493701: performance enhancements for struct module.
1635
Georg Brandl378d5922006-05-17 14:26:50 +00001636- Patch #1490224: time.altzone is now set correctly on Cygwin.
1637
Georg Brandl8d3342b2006-05-16 07:38:27 +00001638- Patch #1435422: zlib's compress and decompress objects now have a
1639 copy() method.
1640
Andrew MacIntyre92913322006-06-13 15:04:24 +00001641- Patch #1454481: thread stack size is now tunable at runtime for thread
1642 enabled builds on Windows and systems with Posix threads support.
1643
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001644- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1645 (up to the system limit of 32K characters).
1646
1647- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1648 As a result, these functions now raise WindowsError instead of OSError.
1649
Tim Peters7a822da2006-05-25 21:50:17 +00001650- ``time.clock()`` on Win64 should use the high-performance Windows
1651 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1652 Windows platforms).
1653
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001654- Calling Tk_Init twice is refused if the first call failed as that
1655 may deadlock.
1656
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001657- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1658 accept it without potentially using an uninitialized pointer.
1659
1660- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1661 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1662 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001663
Gregory P. Smith372b5832006-06-05 18:48:21 +00001664- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001665 [pybsddb project SF patch number 1466734]
1666
Gregory P. Smith372b5832006-06-05 18:48:21 +00001667- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1668 parameter is supplied. [SF pybsddb bug #1477863]
1669
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001670- bsddb: the __len__ method of a DB object has been fixed to return correct
1671 results. It could previously incorrectly return 0 in some cases.
1672 Fixes SF bug 1493322 (pybsddb bug 1184012).
1673
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001674- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1675 aborts the db transaction safely when a modifier callback fails.
1676 Fixes SF python patch/bug #1408584.
1677
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001678- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001679 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001680 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1681 database calls that would previously deadlock. [SF python bug #775414]
1682
Vinay Sajip28e57612006-07-01 10:45:20 +00001683- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001684
Walter Dörwald4994d952006-06-19 08:07:50 +00001685- Patch #1506645: add Python wrappers for the curses functions
1686 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001687

1689-------
1690
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001691- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1692 functions.
1693
Martin v. Löwis3798da02006-06-17 18:44:27 +00001694- Patch #812986: Update turtle output even if not tracing.
1695
Vinay Sajip28e57612006-07-01 10:45:20 +00001696- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001697 Tkinter.BaseWidget.
1698
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001699- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1700
Martin v. Löwis337487e2006-06-17 09:15:14 +00001701- Patch #763580: Add name and value arguments to Tkinter variable
1702 classes.
1703
Georg Brandl83cc0d02006-06-14 08:50:03 +00001704- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1705 mime.types file for determining MIME types.
1706
Georg Brandl2605ca82006-06-14 06:08:31 +00001707- Bug #1339007: Shelf objects now don't raise an exception in their
1708 __del__ method when initialization failed.
1709
Martin v. Löwisd8251432006-06-14 05:21:04 +00001710- Patch #1455898: The MBCS codec now supports the incremental mode for
1711 double-byte encodings.
1712
Tim Peters43898b42006-06-14 04:09:25 +00001713- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1714 guarantee that adjacent triples in the return list always describe
1715 non-adjacent blocks. Previously, a pair of matching blocks could end
1716 up being described by multiple adjacent triples that formed a partition
1717 of the matching pair.
1718
Greg Ward0e0c9f42006-06-11 16:24:11 +00001719- Bug #1498146: fix optparse to handle Unicode strings in option help,
1720 description, and epilog.
1721
Greg Wardd1c797e2006-06-11 14:42:41 +00001722- Bug #1366250: minor optparse documentation error.
1723
Greg Ward7f547402006-06-11 00:40:49 +00001724- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1725 clarify docs.
1726
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001727- The wsgiref package has been added to the standard library.
1728
Nick Coghlan676725d2006-06-08 13:54:49 +00001729- The functions update_wrapper() and wraps() have been added to the functools
1730 module. These make it easier to copy relevant metadata from the original
1731 function when writing wrapper functions.
1732
Tim Petersd6a9eef2006-06-05 01:48:21 +00001733- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1734 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001735
Martin v. Löwis3f767792006-06-04 19:36:28 +00001736- Patch #1359618: Speed up charmap encoder by using a trie structure
1737 for lookup.
1738
Tim Petersd609b1a2006-06-02 23:22:51 +00001739- The functions in the ``pprint`` module now sort dictionaries by key
1740 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1741 if and only if its display required more than one line, although that
1742 wasn't documented. The new behavior increases predictability; e.g.,
1743 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1744
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001745- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1746 (thanks for J. J. Lee).
1747

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001815What's New in Python 2.5 alpha 2?
1816=================================
1817
1818*Release date: 27-APR-2006*
1819
1820Core and builtins
1821-----------------
1822
Thomas Heller1b046642006-04-18 18:51:06 +00001823- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1824 by converting these apis from macros into exported functions again:
1825
1826 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1827 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1828 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1829 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1830 PyRun_String Py_CompileString
1831
Martin v. Löwis45294a92006-04-18 06:24:08 +00001832- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1833
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001834- All uses of PyStructSequence_InitType have been changed to initialize
1835 the type objects only once, even if the interpreter is initialized
1836 multiple times.
1837
Neal Norwitz61546162006-04-14 05:20:28 +00001838- Bug #1454485, array.array('u') could crash the interpreter. This was
1839 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1840 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1841
1842- Py_UNICODE is unsigned. It was always documented as unsigned, but
1843 due to a bug had a signed value in previous versions.
1844
Tim Peters3a5e8b12006-04-11 01:44:07 +00001845- Patch #837242: ``id()`` of any Python object always gives a positive
1846 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1847 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001848 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001849 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001850
Tim Peters3a5e8b12006-04-11 01:44:07 +00001851 def __hash__(self):
1852 return id(self) # WRONG
1853
1854 because a hash result must be a (short) Python int but it was always
1855 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001856 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001857 was always usable as a hash value before this patch. That's no longer
1858 necessarily so.
1859
1860- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001861 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001862 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001863 #1454844)
1864
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001865- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1866 involving generators that have paused outside of any ``try`` or ``with``
1867 blocks. (In 2.5a1, a paused generator that was part of a reference
1868 cycle could not be garbage collected, regardless of whether it was
1869 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001870
Anthony Baxter51bcb682006-04-05 14:51:42 +00001871Extension Modules

Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001874- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1875 is a macro.
1876
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001877- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1878 fails with an error condition.
1879
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001880- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1881
1882- Bug #1117761: bsddb.*open() no longer raises an exception when using
1883 the cachesize parameter.
1884
1885- Bug #1149413: bsddb.*open() no longer raises an exception when using
1886 a temporary db (file=None) with the 'n' flag to truncate on open.
1887
1888- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1889 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001890
Armin Rigoa9017c32006-04-19 11:50:27 +00001891- Patch #1062014: AF_UNIX sockets under Linux have a special
1892 abstract namespace that is now fully supported.

1895-------
1896
Peter Astrand7d1d4362006-07-14 14:04:45 +00001897- Bug #1223937: subprocess.CalledProcessError reports the exit status
1898 of the process using the returncode attribute, instead of
1899 abusing errno.
1900
Tim Peters711bf302006-04-25 03:31:36 +00001901- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1902 a doctest to be skipped (the code is not run, and the expected output
1903 or exception is ignored).
1904
Nick Coghlanda2268f2006-04-24 04:37:15 +00001905- Fixed contextlib.nested to cope with exceptions being raised and
1906 caught inside exit handlers.
1907
Greg Wardab05edc2006-04-23 03:47:58 +00001908- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1909 hex, octal, or binary; add ``append_const`` action; keep going if
1910 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1911 added ``epilog`` for better help generation).
1912
Tim Peters21fbd572006-04-21 21:18:10 +00001913- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1914 called from a thread spawned as a side effect of importing a module.
1915
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001916- The pydoc module now supports documenting packages contained in
1917 .zip or .egg files.
1918
1919- The pkgutil module now has several new utility functions, such
1920 as ``walk_packages()`` to support working with packages that are either
1921 in the filesystem or zip files.
1922
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001923- The mailbox module can now modify and delete messages from
1924 mailboxes, in addition to simply reading them. Thanks to Gregory
1925 K. Johnson for writing the code, and to the 2005 Google Summer of
1926 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001927
Tim Petersc7605f22006-04-17 21:12:33 +00001928- The ``__del__`` method of class ``local`` in module ``_threading_local``
1929 returned before accomplishing any of its intended cleanup.
1930
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001931- Patch #790710: Add breakpoint command lists in pdb.
1932
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001933- Patch #1063914: Add Tkinter.Misc.clipboard_get().

Martin v. Löwis4b501e62006-04-15 08:41:11 +00001935- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1936
Anthony Baxtere29002c2006-04-12 12:07:31 +00001937- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1938 Windows. Bug #1469163.
1939
Phillip J. Eby47032112006-04-11 01:07:43 +00001940- The warnings, linecache, inspect, traceback, site, and doctest modules
1941 were updated to work correctly with modules imported from zipfiles or
1942 via other PEP 302 __loader__ objects.
1943
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001944- Patch #1467770: Reduce usage of subprocess._active to processes which
1945 the application hasn't waited on.
1946
Martin v. Löwisb04dee92006-04-10 08:34:21 +00001947- Patch #1462222: Fix Tix.Grid.

1950
Skip Montanaro262fb922006-04-21 02:31:07 +00001951- The pstats.Stats class accepts an optional stream keyword argument to
1952 direct output to an alternate file-like object.
1953
Anthony Baxter51bcb682006-04-05 14:51:42 +00001954Build
1955-----
1956
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001957- The Makefile now has a reindent target, which runs reindent.py on
1958 the library.
1959
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001960- Patch #1470875: Building Python with MS Free Compiler
1961
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001962- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001963
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001964- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1965 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001966 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001967 CXX from --with-cxx-main, see description in README.
1968
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001969- Patch #1429775: Link extension modules with the shared libpython.
1970
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001971- Fixed a libffi build problem on MIPS systems.
1972
Tim Peters8931ff12006-05-13 23:28:20 +00001973- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1974 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1975 and "%zu" for unsigned integers of type ``size_t``.
1976
Anthony Baxter51bcb682006-04-05 14:51:42 +00001977Tests
1978-----
1979
Nick Coghlanda2268f2006-04-24 04:37:15 +00001980- test_contextlib now checks contextlib.nested can cope with exceptions
1981 being raised and caught inside exit handlers.
1982
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001983- test_cmd_line now checks operation of the -m and -c command switches
1984
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001985- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1986 it separately and by hand. It also wasn't cleaning up its changes to
1987 the current Decimal context.
1988
Thomas Woutersabd08882006-04-26 15:53:30 +00001989- regrtest.py now has a -M option to run tests that test the new limits of
1990 containers, on 64-bit architectures. Running these tests is only sensible
1991 on 64-bit machines with more than two gigabytes of memory. The argument
1992 passed is the maximum amount of memory for the tests to use.

2001-------------
2002
Tim Petersb06d28c2006-05-12 01:57:59 +00002003- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2004
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002005- PEP 343: Added Context Types section to the library reference
2006 and attempted to bring other PEP 343 related documentation into
2007 line with the implementation and/or python-dev discussions.
2008
Tim Peters8dc73d22006-04-24 02:03:16 +00002009- Bug #1337990: clarified that ``doctest`` does not support examples
2010 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002013What's New in Python 2.5 alpha 1?
2014=================================
2015
Anthony Baxterebed3f62006-04-03 15:03:44 +00002016*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002017
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002018Core and builtins
2019-----------------
2020
Nick Coghlan43832302006-04-23 17:04:07 +00002021- PEP 338: -m command line switch now delegates to runpy.run_module
2022 allowing it to support modules in packages and zipfiles
2023
Martin v. Löwisc661b882006-04-20 04:54:23 +00002024- On Windows, .DLL is not an accepted file name extension for
2025 extension modules anymore; extensions are only found if they
2026 end in .PYD.
2027
Martin v. Löwisea62d252006-04-03 10:56:49 +00002028- Bug #1421664: sys.stderr.encoding is now set to the same value as
2029 sys.stdout.encoding.
2030
Neal Norwitz92e212f2006-04-03 04:48:37 +00002031- __import__ accepts keyword arguments.
2032
Georg Brandlccadf842006-03-31 18:54:53 +00002033- Patch #1460496: round() now accepts keyword arguments.
2034
Anthony Baxter262c00a2006-03-30 10:53:17 +00002035- Fixed bug #1459029 - unicode reprs were double-escaped.
2036
Hye-Shik Changd478f342006-03-23 12:32:36 +00002037- Patch #1396919: The system scope threads are reenabled on FreeBSD
2038 5.4 and later versions.
2039
Neal Norwitze98ccf62006-03-23 05:39:47 +00002040- Bug #1115379: Compiling a Unicode string with an encoding declaration
2041 now gives a SyntaxError.
2042
Georg Brandlabd1ff82006-03-18 07:59:59 +00002043- Previously, Python code had no easy way to access the contents of a
2044 cell object. Now, a ``cell_contents`` attribute has been added
2045 (closes patch #1170323).
2046
Tim Peterscf79aac2006-03-16 01:14:46 +00002047- Patch #1123430: Python's small-object allocator now returns an arena to
2048 the system ``free()`` when all memory within an arena becomes unused
2049 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2050 freed. Some applications will see a drop in virtual memory size now,
2051 especially long-running applications that, from time to time, temporarily
2052 use a large number of small objects. Note that when Python returns an
2053 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002054 platform C library will in turn return that memory to the operating system.
2055 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002056 appears to be effective at least on Microsoft C and gcc-based systems.
2057 Thanks to Evan Jones for hard work and patience.
2058
Georg Brandl533ff6f2006-03-08 18:09:27 +00002059- Patch #1434038: property() now uses the getter's docstring if there is
2060 no "doc" argument given. This makes it possible to legitimately use
2061 property() as a decorator to produce a read-only property.
2062
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002063- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2064 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2065 of requiring an int or long in slicing and a few other contexts, enabling
2066 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2067
Neal Norwitz995acdf2006-03-07 05:01:00 +00002068- Fixed various bugs reported by Coverity's Prevent tool.
2069
Brett Cannonbf364092006-03-01 04:25:17 +00002070- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2071 new exception base class, BaseException, which has a new message attribute.
2072 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2073 Raising a string exception now raises a DeprecationWarning.
2074
Thomas Woutersfb609f42006-02-28 16:37:25 +00002075- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2076 explicitly relative, using 'from .module import name' to mean 'from the same
2077 package as this module is in. Imports without dots still default to the
2078 old relative-then-absolute, unless 'from __future__ import
2079 absolute_import' is used.
2080
Brett Cannona7446e32006-02-27 23:39:10 +00002081- Properly check if 'warnings' raises an exception (usually when a filter set
2082 to "error" is triggered) when raising a warning for raising string
2083 exceptions.
2084
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002085- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002086 The name was removed from Include/code.h.
2087
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002088- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002089
Guido van Rossum1968ad32006-02-25 22:38:04 +00002090- Patch 1433928:
2091 - The copy module now "copies" function objects (as atomic objects).
2092 - dict.__getitem__ now looks for a __missing__ hook before raising
2093 KeyError.
2094
Tim Peters84ef21c2006-02-28 20:39:06 +00002095- PEP 343: with statement implemented. Needs ``from __future__ import
2096 with_statement``. Use of 'with' as a variable will generate a warning.
2097 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002098 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002099 The following objects have __context__ methods:
2100 - The built-in file type.
2101 - The thread.LockType type.
2102 - The following types defined by the threading module:
2103 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2104 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002105
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002106- Fix the encodings package codec search function to only search
2107 inside its own package. Fixes problem reported in patch #1433198.
2108
2109 Note: Codec packages should implement and register their own
2110 codec search function. PEP 100 has the details.
2111
Tim Peters9ea89d22006-06-04 03:26:02 +00002112- PEP 353: Using ``Py_ssize_t`` as the index type.
2113
2114- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2115 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2116 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2117 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2118 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002119
Neal Norwitzfc76d632006-01-10 06:03:13 +00002120- Patch #1400181, fix unicode string formatting to not use the locale.
2121 This is how string objects work. u'%f' could use , instead of .
2122 for the decimal point. Now both strings and unicode always use periods.
2123
Neal Norwitz671b9e32006-01-09 07:07:12 +00002124- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2125 configure would break checking curses.h.
2126
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002127- Bug #959576: The pwd module is now builtin. This allows Python to be
2128 built on UNIX platforms without $HOME set.
2129
Neal Norwitzc10978f2005-12-19 06:07:16 +00002130- Bug #1072182, fix some potential problems if characters are signed.
2131
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002132- Bug #889500, fix line number on SyntaxWarning for global declarations.
2133
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002134- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2135
Neal Norwitze7214a12005-12-18 05:03:17 +00002136- Support for converting hex strings to floats no longer works.
2137 This was not portable. float('0x3') now raises a ValueError.
2138
Barry Warsaw2a38a862005-12-18 01:27:35 +00002139- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002140 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002141 is now displayed in interactive prompt banner.
2142
Georg Brandlfa166682005-12-17 21:45:17 +00002143- Implementation of PEP 341 - Unification of try/except and try/finally.
2144 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002145 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002146
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002147- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2148 now encodes backslash correctly.
2149
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002150- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2151
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002152- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002153 and long longs.
2154
Neal Norwitz67715f02005-11-09 06:59:35 +00002155- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002156 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002157 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002158
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002159- Replaced most Unicode charmap codecs with new ones using the
2160 new Unicode translate string feature in the builtin charmap
2161 codec; the codecs were created from the mapping tables available
2162 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2163 encodings now include a mapping for the Apple logo)
2164
Tim Peterse3547fd2005-12-16 23:13:57 +00002165- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002166
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002167- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002168
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002169- A new AST parser implementation was completed. The abstract
2170 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002171 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002172
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002173- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002174 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2175
Neal Norwitz708e51a2005-10-03 04:48:15 +00002176- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2177
Neal Norwitz11bd1192005-10-03 00:54:56 +00002178- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2179 Provide a warning when a directory is passed on the command line.
2180
Neal Norwitz40d37812005-10-02 01:48:49 +00002181- Fix segfault with invalid coding.
2182
2183- SF bug #772896: unknown encoding results in MemoryError.
2184
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002185- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002186 supported a __len__() method which evaluated to False when the iterator
2187 was empty.
2188
Guido van Rossum630db602005-09-20 18:49:54 +00002189- On 64-bit platforms, when __len__() returns a value that cannot be
2190 represented as a C int, raise OverflowError.
2191
Skip Montanarof8948ca2005-09-19 03:54:46 +00002192- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002193 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002194
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002195- SF bug #893549: parsing keyword arguments was broken with a few format
2196 codes.
2197
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002198- Changes donated by Elemental Security to make it work on AIX 5.3
2199 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2200 bug #105470: test_pwd fails on 64bit system (Opteron).
2201
Guido van Rossum539c6622005-09-14 17:49:54 +00002202- Changes donated by Elemental Security to make it work on HP-UX 11 on
2203 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2204
Georg Brandl4550b8d2005-08-26 06:43:52 +00002205- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002206 (fixes bug #1119418).
2207
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002208- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2209
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002210- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2211 exceptions that cause a function to exit.
2212
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002213- The implementation of set() and frozenset() was revised to use its
2214 own internal data structure. Memory consumption is reduced by 1/3
2215 and there are modest speed-ups as well. The API is unchanged.
2216
Tim Petersde7990b2005-07-17 23:45:23 +00002217- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2218
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002219- SF bug #1229429: PyObject_CallMethod failed to decrement some
2220 reference counts in some error exit cases.
2221
Tim Petersecc6e6a2005-07-10 22:30:55 +00002222- SF bug #1185883: Python's small-object memory allocator took over
2223 a block managed by the platform C library whenever a realloc specified
2224 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002225 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002226 portable way to copy data from the C-managed block into Python's
2227 small-object space without risking a memory fault. Python's small-object
2228 realloc now leaves such blocks under the control of the platform C
2229 realloc.
2230
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002231- SF bug #1232517: An overflow error was not detected properly when
2232 attempting to convert a large float to an int in os.utime().
2233
Raymond Hettinger3296e692005-06-29 23:29:56 +00002234- SF bug #1224347: hex longs now print with lowercase letters just
2235 like their int counterparts.
2236
Michael W. Hudson188d4362005-06-20 16:52:57 +00002237- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2238 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2239 interpreter states; back out that fix and do a better job (see
2240 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2241 for a longer write-up of the problem).
2242
Michael W. Hudsondf888462005-06-03 14:41:55 +00002243- SF patch #1180995: marshal now uses a binary format by default when
2244 serializing floats.
2245
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002246- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2247 the routines that promise to produce IEEE 754 binary representations
2248 of floats now simply copy bytes around.
2249
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002250- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2251 278.
2252
Brett Cannonc3647ac2005-04-26 03:45:26 +00002253- patch #1109424: int, long, float, complex, and unicode now check for the
2254 proper magic slot for type conversions when subclassed. Previously the
2255 magic slot was ignored during conversion. Semantics now match the way
2256 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002257 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002258 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002259 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002260
Barry Warsawc8d907c2005-04-19 23:43:40 +00002261- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2262 NULL, now raise an AttributeError when attempting to set or delete the
2263 attribute. Previously a TypeError was raised, but this was inconsistent
2264 with the equivalent pure-Python implementation.
2265
Michael W. Hudson774479c2005-04-18 08:46:17 +00002266- It is now safe to call PyGILState_Release() before
2267 PyEval_InitThreads() (note that if there is reason to believe there
2268 are multiple threads around you still must call PyEval_InitThreads()
2269 before using the Python API; this fix is for extension modules that
2270 have no way of knowing if Python is multi-threaded yet).
2271
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002272- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2273 disabled caused a crash.
2274
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002275- Bug #1165306: instancemethod_new allowed the creation of a method
2276 with im_class == im_self == NULL, which caused a crash when called.
2277
Tim Petersecc6e6a2005-07-10 22:30:55 +00002278- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002279 fixes the crash seen in bug #1165761
2280
Raymond Hettinger96229b12005-03-11 06:49:40 +00002281- Added two new builtins, any() and all().
2282
Brett Cannon409d8f22005-03-05 06:47:57 +00002283- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002284 (e.g., ``class C(): pass`` is no longer a syntax error).
2285 Patch #1176012 added support to the 'parser' module and 'compiler' package
2286 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002287
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002288- Patch #1115086: Support PY_LONGLONG in structmember.
2289
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002290- Bug #1155938: new style classes did not check that __init__() was
2291 returning None.
2292
Tim Petersecc6e6a2005-07-10 22:30:55 +00002293- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002294 ('\') with a specific error message.
2295
Martin v. Löwisff232d72005-03-03 09:24:38 +00002296- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2297
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002298- Bug #1124295: the __name__ attribute of file objects was
2299 inadvertently made inaccessible in restricted mode.
2300
Tim Petersecc6e6a2005-07-10 22:30:55 +00002301- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002302 an ferror() call.
2303
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002304- min() and max() now support key= arguments with the same meaning as in
2305 list.sort().
2306
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002307- The peephole optimizer now performs simple constant folding in expressions:
2308 (2+3) --> (5).
2309
Raymond Hettingera422c342005-01-11 03:03:27 +00002310- set and frozenset objects can now be marshalled. SF #1098985.
2311
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002312- Bug #1077106: Poor argument checking could cause memory corruption
2313 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002314
Jeremy Hyltonab630502005-02-04 18:44:06 +00002315- The parser did not complain about future statements in illegal
2316 positions. It once again reports a syntax error if a future
2317 statement occurs after anything other than a doc string.
2318
Neil Schemenauercf52c072005-08-12 17:34:58 +00002319- Change the %s format specifier for str objects so that it returns a
2320 unicode instance if the argument is not an instance of basestring and
2321 calling __str__ on the argument returns a unicode instance.
2322
Tim Petersf4e69282006-02-27 17:15:31 +00002323- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2324 current thread state when the auto-GIL-state machinery knows about
2325 it (since the thread state is being deleted, continuing to remember it
2326 can't help, but can hurt if another thread happens to get created with
2327 the same thread id).

2460 the request code argument, which results in more C-like behaviour
2461 for large or negative values.
2462
Tim Petersecc6e6a2005-07-10 22:30:55 +00002463- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

2478
Raymond Hettinger984f9bb2005-03-09 16:38:48 +00002479- operator.itemgetter() and operator.attrgetter() now support retrieving

Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002503- the cPickle module no longer accepts the deprecated None option in the
2504 args tuple returned by __reduce__().
2505
Raymond Hettingerb2594052004-12-05 09:25:51 +00002506- itertools.islice() now accepts None for the start and step arguments.
2507 This allows islice() to work more readily with slices:
2508 islice(s.start, s.stop, s.step)
2509
Skip Montanaro0af3ade2005-01-13 04:12:31 +00002510- datetime.datetime() now has a strptime class method which can be used to

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002519- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2520 been renamed to have only a single underscore prefix. This was done to
2521 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002522
Nick Coghlan43832302006-04-23 17:04:07 +00002523- PEP 338: new module runpy defines a run_module function to support
2524 executing modules which provide access to source code or a code object
2525 via the PEP 302 import mechanisms.
2526
Anthony Baxter93f5b932006-04-03 08:05:07 +00002527- The email module's parsedate_tz function now sets the daylight savings

2535 in attribute values.
2536
Anthony Baxterc51ee692006-04-01 00:57:31 +00002537- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002538 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002539 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002540 module will not be built.
2541
Tim Petersc17976e2006-04-01 00:26:53 +00002542- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2543 aren't officially supported here, and trying to use them will probably
2544 raise an exception some day. But dicts have been allowed, and "mostly
2545 worked", so support for them won't go away without warning.
2546
Georg Brandl338ef7d2006-03-31 18:42:16 +00002547- Bug #1445068: getpass.getpass() can now be given an explicit stream
2548 argument to specify where to write the prompt.
2549
Georg Brandl22ec80b2006-03-31 18:25:44 +00002550- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2565
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002566- email 4.0 package now integrated. This is largely the same as the email 3.0
2567 package that was included in Python 2.3, except that PEP 8 module names are
2568 now used (e.g. mail.message instead of email.Message). The MIME classes
2569 have been moved to a subpackage (e.g. email.mime.text instead of
2570 email.MIMEText). The old names are still supported for now. Several
2571 deprecated Message methods have been removed and lots of bugs have been
2572 fixed. More details can be found in the email package documentation.
2573
Walter Dörwald40108c92006-03-27 08:15:44 +00002574- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2575 (a subclass of tuple) that provides incremental decoders and encoders
2576 (a way to use stateful codecs without the stream API). Python functions
2577 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2578 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2579 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00002581- Patch #1359365: Calling next() on a closed StringIO.String object raises
2582 a ValueError instead of a StopIteration now (like file and cString.String do).
2583 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2584 called before (like file and StringIO.StringIO do).

2663 "The consensus of researchers in this area (at least as
2664 expressed at the NIST Hash Function Workshop 10/31/05),
2665 is that SHA-256 is a good choice for the time being, but
2666 that research should continue, and other alternatives may
2667 arise from this research. The larger SHA's also seem OK."

Martin v. Löwis22b457e2005-01-16 08:40:58 +00002845- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2846
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002847- Enhancements to the csv module:
2848
2849 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002850 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002851 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002852 + Dialect parameter parsing has been re-implemented to improve error
2853 reporting.
2854 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2855 dictates.
2856 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002857 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002858 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002859 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2860 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002861 + reader now allows \r characters to be quoted (previously it only allowed
2862 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002863 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002864 + Dialect classes passed to the module are no longer instantiated by
2865 the module before being parsed (the former validation scheme required
2866 this, but the mechanism was unreliable).
2867 + The dialect registry now contains instances of the internal
2868 C-coded dialect type, rather than references to python objects.
2869 + the internal c-coded dialect type is now immutable.
2870 + register_dialect now accepts the same keyword dialect specifications
2871 as the reader and writer, allowing the user to register dialects
2872 without first creating a dialect class.
2873 + a configurable limit to the size of parsed fields has been added -
2874 previously, an unmatched quote character could result in the entire
2875 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002876 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002877 the parser field size limit (returning the former limit). The initial
2878 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002879 + A line_num attribute has been added to the reader object, which tracks
2880 the number of lines read from the source iterator. This is not
2881 the same as the number of records returned, as records can span
2882 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002883 + reader and writer objects were not being registered with the cyclic-GC.
2884 This has been fixed.
2885
Brett Cannone6539c42005-01-08 02:43:53 +00002886- _DummyThread objects in the threading module now delete self.__block that is
2887 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2888 lock primitives tend to be limited in number and thus should not be wasted on
2889 a _DummyThread object. Fixes bug #1089632.
2890
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002891- The imghdr module now detects Exif files.
2892
Raymond Hettinger6065d322004-12-20 23:51:53 +00002893- StringIO.truncate() now correctly adjusts the size attribute.
2894 (Bug #951915).
2895
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002896- locale.py now uses an updated locale alias table (built using
2897 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2898 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002899 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002900
Raymond Hettinger3557f422004-12-07 12:02:02 +00002901- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2902
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002903- the pickle module no longer accepts the deprecated None option in the
2904 args tuple returned by __reduce__().
2905
Brett Cannon84667c02004-12-07 03:25:18 +00002906- optparse now optionally imports gettext. This allows its use in setup.py.
2907
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002908- the pickle module no longer uses the deprecated bin parameter.
2909
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002910- the shelve module no longer uses the deprecated binary parameter.
2911
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002912- the pstats module no longer uses the deprecated ignore() method.
2913
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002914- the filecmp module no longer uses the deprecated use_statcache argument.
2915
Raymond Hettinger664347b2004-12-04 21:21:53 +00002916- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2917 extended or overridden by subclasses. Formerly, the subclassed method would
2918 be ignored by the rest of the module. (Bug #1078905).
2919
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002920- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002921 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002922
Walter Dörwald36733692004-12-22 12:50:50 +00002923- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2924 once when a size argument is given. This prevents a buffer overflow in the
2925 tokenizer with very long source lines.
2926
Barry Warsaw538561e2006-01-01 21:48:54 +00002927- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2928 immediately after creating the object, without any intervening
2929 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002930
Skip Montanaro05885812005-01-16 20:48:27 +00002931- The reconvert.quote function can now emit triple-quoted strings. The
2932 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002933
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002934- ``UserString.MutableString`` now supports negative indices in
2935 ``__setitem__`` and ``__delitem__``
2936
Greg Ward40407942005-03-05 02:53:17 +00002937- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2938 correctly.
2939
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002940- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2941 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2942 character even if the user has passed a size parameter to get a proper
2943 line ending. Remove the special handling of a "\r\n" that has been split
2944 between two lines.
2945
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002946- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2947 about illegal code points. The codec now supports PEP 293 style error
2948 handlers.
2949
Walter Dörwald78a78b02005-09-01 12:04:29 +00002950- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002951 from the input stream, so that the output is a byte string in the correct
2952 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002953
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002954- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2955 considering it exactly like a '*'.
2956
Walter Dörwald007f8df2005-10-09 19:42:27 +00002957- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2958 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002959
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002960- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2961
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002962- Patch #1413711: Certain patterns of differences were making difflib
2963 touch the recursion limit.
2964
Walter Dörwald58917a62006-03-31 15:26:22 +00002965- Bug #947906: An object oriented interface has been added to the calendar
2966 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002967 called as a script (e.g. via ``python -mcalendar``). Localized month and
2968 weekday names can be ouput (even if an exotic encoding is used) using
2969 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002970
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002971Build
2972-----
2973
Neal Norwitz602d3392006-03-31 08:21:40 +00002974- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2975 by using -mieee gcc option.
2976

2978
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002979- Build support for Win64-AMD64 was added.
2980
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002981- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2982
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002983- Patch #881820: look for openpty and forkpty also in libbsd.
2984
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002985- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2986 The zlib module is now builtin on Windows.
2987
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002988- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2989
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002990- Bug #1189330: configure did not correctly determine the necessary
2991 value of LINKCC if python was built with GCC 4.0.
2992
Trent Mick8321b422005-07-26 02:29:21 +00002993- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2994 vulnerability in zlib 1.2.1 and 1.2.2.
2995
Brett Cannon08cd5982005-04-24 22:26:38 +00002996- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2997 flags that change binary compatibility. Changes were also made to
2998 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002999 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003000
Bob Ippolitoed233462005-03-29 13:47:59 +00003001- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3002 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3003 no longer exists). This configure patch makes things right.
3004
Martin v. Löwise2713be2005-03-08 15:03:08 +00003005- Bug #1158607: Build with --disable-unicode again.
3006
Brett Cannon46d96232005-02-16 00:07:19 +00003007- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3008 defined. Discovered as a result of not being able to build on OS X.
3009
Brett Cannon516592f2004-12-07 00:42:59 +00003010- setup.py now uses the directories specified in LDFLAGS using the -L option
3011 and in CPPFLAGS using the -I option for adding library and include
3012 directories, respectively, for compiling extension modules against. This has
3013 led to the core being compiled using the values in CPPFLAGS. It also removes
3014 the need for the special-casing of both DarwinPorts and Fink for darwin since
3015 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3016 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3017 Fink, ``-I/opt/local/include`` for DarwinPorts).
3018
Brett Cannon43802422005-02-10 20:48:03 +00003019- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3020 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3021 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3022 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003024C API
3025-----
3026
Tim Petersc9d78aa2006-03-26 23:27:58 +00003027- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3028 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3029 is obtained via the ``PyObject_`` family, it must be released via the
3030 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3031 always been officially true, but when Python's small-object allocator was
3032 introduced, an attempt was made to cater to a few extension modules
3033 discovered at the time that obtained memory via ``PyObject_New`` but
3034 released it via ``PyMem_DEL``. It's years later, and if such code still
3035 exists it will fail now (probably with segfaults, but calling wrong
3036 low-level memory management functions can yield many symptoms).
3037
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003038- Added a C API for set and frozenset objects.
3039
Raymond Hettinger66517482004-12-03 11:45:13 +00003040- Removed PyRange_New().
3041
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003042- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3043 mapping argument now. This string is used as a mapping table. Byte values
3044 greater than the length of the string and 0xFFFE are treated as undefined
3045 mappings.
