Neal Norwitz0ac60192007-05-27 04:08:54 +000035- Add new attribute names for function objects. All the func_* become
36 __*__ attributes. (Some already existed, e.g., __doc__ and __name__.)
37
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +000038- Add -3 option to the interpreter to warn about features that are
39 deprecated and will be changed/removed in Python 3.0.
40
Georg Brandl2134e752007-05-21 20:34:16 +000041- Patch #1686487: you can now pass any mapping after '**' in function
42 calls.
43
Collin Winter62903052007-05-18 23:11:24 +000044- except clauses may now be spelled either "except E, target:" or
45 "except E as target:". This is to provide forwards compatibility with
46 Python 3.0.
47
Brett Cannon229cee22007-05-05 01:34:02 +000048- Deprecate BaseException.message as per PEP 352.

51 inherited from a builtin base.
52
Vinay Sajip8549ce32007-05-06 17:53:37 +000053- When __slots__ are set to a unicode string, make it work the same as

55
Raymond Hettinger13936692007-04-11 18:40:58 +000056- Request #1191699: Slices can now be pickled.
57
Raymond Hettinger4db5fe92007-04-12 04:10:00 +000058- Request #1193128: str.translate() now allows a None argument for
59 translations that only remove characters without re-mapping the
60 remaining characters.
61
Georg Brandl5cb76c12007-03-21 09:00:39 +000062- Patch #1682205: a TypeError while unpacking an iterable is no longer
63 masked by a generic one with the message "unpack non-sequence".
64
Neal Norwitzaa754b72007-03-21 06:39:48 +000065- Remove unused file Python/fmod.c.
66
Guido van Rossum143b5642007-03-23 04:58:42 +000067- Bug #1683368: The object.__init__() and object.__new__() methods are
68 now stricter in rejecting excess arguments. The only time when
69 either allows excess arguments is when it is not overridden and the
70 other one is. For backwards compatibility, when both are
71 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +000072 warning later). Also, type.__init__() insists on the same signature
73 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +000074
Georg Brandl2b869942007-03-17 16:08:45 +000075- Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
76 to complex using its __complex__() method before falling back to the
77 __float__() method. Therefore, the functions in the cmath module now
78 can operate on objects that define a __complex__() method.
79
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +000080- Patch #1623563: allow __class__ assignment for classes with __slots__.
81 The old and the new class are still required to have the same slot names.
82
Collin Winter77c67bd2007-03-16 04:11:30 +000083- Patch #1642547: Fix an error/crash when encountering syntax errors in
84 complex if statements.
85
Žiga Seilnacht20f43d32007-03-15 11:44:55 +000086- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
87 is called with an object that is faking its type.
88
Žiga Seilnacht71436f02007-03-14 12:24:09 +000089- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
90 name.
91
Georg Brandl5240d742007-03-13 20:46:32 +000092- Patch #1444529: the builtin compile() now accepts keyword arguments.
93
Georg Brandl7b9c5552007-03-12 14:30:05 +000094- Bug #1678647: write a newline after printing an exception in any
95 case, even when converting the value to a string failed.
96
Georg Brandl871f1bc2007-03-12 13:17:36 +000097- The dir() function has been extended to call the __dir__() method on
98 its argument, if it exists. If not, it will work like before. This allows
99 customizing the output of dir() in the presence of a __getattr__().
100
Collin Winter276887b2007-03-12 16:11:39 +0000101- Patch #922167: Python no longer segfaults when faced with infinitely
102 self-recursive reload() calls (as reported by bug #742342).
103
Žiga Seilnacht89032082007-03-11 15:54:54 +0000104- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
105
Collin Wintere38051d2007-03-09 20:33:07 +0000106- Patch #1491866: change the complex() constructor to allow parthensized
107 forms. This means complex(repr(x)) now works instead of raising a
108 ValueError.
109
Georg Brandlaa2321b2007-03-07 00:40:28 +0000110- Patch #703779: unset __file__ in __main__ after running a file. This
111 makes the filenames the warning module prints much more sensible when
112 a PYTHONSTARTUP file is used.
113
Georg Brandl49aafc92007-03-07 00:34:46 +0000114- Variant of patch #697613: don't exit the interpreter on a SystemExit
115 exception if the -i command line option or PYTHONINSPECT environment
116 variable is given, but break into the interactive interpreter just like
117 on other exceptions or normal program exit.
118
Georg Brandl00cd8182007-03-06 18:41:12 +0000119- Patch #1638879: don't accept strings with embedded NUL bytes in long().
120
Georg Brandl098cd692007-03-06 12:17:50 +0000121- Bug #1674503: close the file opened by execfile() in an error condition.
122
Georg Brandl0fca97a2007-03-05 22:28:08 +0000123- Patch #1674228: when assigning a slice (old-style), check for the
124 sq_ass_slice instead of the sq_slice slot.
125
Neal Norwitz88516a62007-02-26 22:41:45 +0000126- When printing an unraisable error, don't print exceptions. before the name.
127 This duplicates the behavior whening normally printing exceptions.
128
Martin v. Löwisfd963262007-02-09 12:19:32 +0000129- Bug #1653736: Properly discard third argument to slot_nb_inplace_power.
130
Brett Cannon129bd522007-01-30 21:34:36 +0000131- PEP 352: Raising a string exception now triggers a TypeError. Attempting to
132 catch a string exception raises DeprecationWarning.
133
Brett Cannonf5bee302007-01-23 23:21:22 +0000134- Bug #1377858: Fix the segfaulting of the interpreter when an object created
135 a weakref on itself during a __del__ call for new-style classes (classic
136 classes still have the bug).
137
Martin v. Löwis6c5c5022007-01-23 21:11:47 +0000138- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
139 frame's thread state.
140

146 raised a warning.
147
Martin v. Löwis7b7c9d42007-01-04 21:06:12 +0000148- Bug #1566280: Explicitly invoke threading._shutdown from Py_Main,

172
Neal Norwitzcbeb6872006-10-14 21:33:38 +0000173- Update the peephole optimizer to remove more dead code (jumps after returns)
174 and inline unconditional jumps to returns.
175
Georg Brandl2c1375c2006-10-12 11:27:59 +0000176- Bug #1545497: when given an explicit base, int() did ignore NULs

183
184- Fix some leftovers from the conversion from int to Py_ssize_t
185 (relevant to strings and sequences of more than 2**31 items).
186
187- A number of places, including integer negation and absolute value,
188 were fixed to not rely on undefined behaviour of the C compiler
189 anymore.

207
Brett Cannon9adeab72006-09-20 18:34:28 +0000208- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This

380

Collin Winterfaaa2042007-03-10 03:35:34 +0000452 be equal to calling getsockname() on the server's socket. Fixed by
453 patch #1545011.
Collin Winter22c42ba2007-03-10 02:51:26 +0000454

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

475 later, with a more cumbersome exception.

506 import semantics.

1025-----------------
1026
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001027- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001028 compared equal or unequal to a string and a UnicodeDecodeError
1029 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001030
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001031 Instead, the equal (==) and unequal (!=) comparison operators will
1032 now issue a UnicodeWarning and interpret the two objects as
1033 unequal. The UnicodeWarning can be filtered as desired using
1034 the warning framework, e.g. silenced completely, turned into an
1035 exception, logged, etc.
1036
1037 Note that compare operators other than equal and unequal will still
1038 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001039
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001040- Fix segfault when doing string formatting on subclasses of long.
1041
1042- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1043 with new-style classes.
1044
1045- Fix bug related to __len__ functions returning negative values with
1046 classic classes.
1047
1048- Patch #1538606, Fix __index__() clipping. There were some problems
1049 discovered with the API and how integers that didn't fit into Py_ssize_t
1050 were handled. This patch attempts to provide enough alternatives
1051 to effectively use __index__.
1052
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001053- Bug #1536021: __hash__ may now return long int; the final hash
1054 value is obtained by invoking hash on the long int.
1055
Thomas Hellerab1049c2006-08-08 17:37:00 +00001056- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1057
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001058- Bug #1535165: fixed a segfault in input() and raw_input() when
1059 sys.stdin is closed.
1060
Thomas Heller74d36f02006-08-04 18:17:40 +00001061- On Windows, the PyErr_Warn function is now exported from
1062 the Python dll again.
1063
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001064- Bug #1191458: tracing over for loops now produces a line event
1065 on each iteration. Fixing this problem required changing the .pyc
1066 magic number. This means that .pyc files generated before 2.5c1
1067 will be regenerated.
1068
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001069- Bug #1333982: string/number constants were inappropriately stored
1070 in the byte code and co_consts even if they were not used, ie
1071 immediately popped off the stack.
1072
Georg Brandle9462c72006-08-04 18:03:37 +00001073- Fixed a reference-counting problem in property().

1076Library
1077-------
1078
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001079- Fix a bug in the ``compiler`` package that caused invalid code to be
1080 generated for generator expressions.
1081
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001082- The distutils version has been changed to 2.5.0. The change to
1083 keep it programmatically in sync with the Python version running
1084 the code (introduced in 2.5b3) has been reverted. It will continue
1085 to be maintained manually as static string literal.
1086
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001087- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001088 and this cannot be converted to the required C type, an exception is
1089 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001090 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001091
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001092- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001093 an exception.
1094
Tim Petersc10c9d02006-09-05 02:18:09 +00001095- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001096 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001097 workarounds for clocks with low resolution, to stop the code yielding
1098 duplicate UUIDs.
1099
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001100- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1101 before raising SystemExit, allowing IDLE to honor quit() and exit().
1102
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001103- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.

Georg Brandl7a1af772006-08-14 21:55:28 +00001105- Patch #1536071: trace.py should now find the full module name of a
1106 file correctly even on Windows.
1107
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001108- logging's atexit hook now runs even if the rest of the module has
1109 already been cleaned up.
1110
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001111- Bug #1112549, fix DoS attack on cgi.FieldStorage.

1114 str(exception) raised an exception.
1115
Neil Schemenauer06ded092006-08-04 16:20:30 +00001116- Fix a bug in the ``compiler`` package that caused invalid code to be
1117 generated for nested functions.

1130
Thomas Heller86720042006-08-14 11:17:48 +00001131- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1132 uses the _as_parameter_ attribute when objects are passed to foreign
1133 function calls. The ctypes version number was changed to 1.0.1.
1134
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001135- Bug #1530559, struct.pack raises TypeError where it used to convert.
1136 Passing float arguments to struct.pack when integers are expected
1137 now triggers a DeprecationWarning.

Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001174- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1175
Tim Peters4643c2f2006-08-10 22:45:34 +00001176- Bug #1069160. Internal correctness changes were made to
1177 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1178 the documentation was changed to state that the return value
1179 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001182What's New in Python 2.5 beta 3?
1183================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001184
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001185*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001186
1187Core and builtins
1188-----------------
1189
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001190- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001191 returned a long (see PEP 353).
1192
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001193- Bug #1515471: string.replace() accepts character buffers again.
1194
Neal Norwitz07aadb12006-07-30 06:55:48 +00001195- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1196 This provides the proper warning for struct.pack().
1197 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1198
Neal Norwitz0d62a062006-07-30 06:53:31 +00001199- Patch #1531113: Fix augmented assignment with yield expressions.
1200 Also fix a SystemError when trying to assign to yield expressions.
1201
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001202- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1203 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1204 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1205 excessive filesystem operations during imports.
1206
Tim Petersbc24eee2006-07-27 01:14:53 +00001207- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1208 operations on signed longs that are formally undefined by C.
1209 Unfortunately, at least one compiler now cares about that, so complicated
1210 the code to make that compiler happy again.
1211
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001212- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1213
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001214- Patch #1232023: Stop including current directory in search
1215 path on Windows.
1216
Neal Norwitze1fdb322006-07-21 05:32:28 +00001217- Fix some potential crashes found with failmalloc.
1218
Neal Norwitze7563102006-07-17 01:00:16 +00001219- Fix warnings reported by Klocwork's static analysis tool.
1220
Neal Norwitz84be93b2006-07-16 01:50:38 +00001221- Bug #1512814, Fix incorrect lineno's when code within a function
1222 had more than 255 blank lines.
1223
Georg Brandl9dceedb2006-07-12 15:31:17 +00001224- Patch #1521179: Python now accepts the standard options ``--help`` and
1225 ``--version`` as well as ``/?`` on Windows.
1226
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001227- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001228 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001229 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001230
Tim Peters112aad32006-07-19 00:03:19 +00001231- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001232 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001233 new ``sys._current_frames()`` returns a dictionary with one entry,
1234 mapping the faux "thread id" 0 to the current frame.
1235
Ronald Oussoren3075e162006-07-25 20:28:55 +00001236- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001237
Ronald Oussoren3075e162006-07-25 20:28:55 +00001238
Neal Norwitza1f10902006-07-12 07:28:29 +00001239Library
1240-------
1241
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001242- Correction of patch #1455898: In the mbcs decoder, set final=False
1243 for stream decoder, but final=True for the decode function.
1244
Georg Brandl07fec3a2006-08-01 18:49:24 +00001245- os.urandom no longer masks unrelated exceptions like SystemExit or
1246 KeyboardInterrupt.
1247
Tim Peters4643c2f2006-08-10 22:45:34 +00001248- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001249 shutil.copytree on Windows
1250
Georg Brandle34ac7c2006-07-30 11:07:23 +00001251- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1252 refers to file descriptors, not file objects.
1253
Tim Petersc10c9d02006-09-05 02:18:09 +00001254- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001255 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001256 #1513611, and probably others.
1257
Georg Brandledd9b0d2006-07-29 09:33:26 +00001258- Bug #1441397: The compiler module now recognizes module and function
1259 docstrings correctly as it did in Python 2.4.
1260
Tim Peters6f681472006-07-27 23:44:37 +00001261- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1262 lost that tests are sorted by name before being run. This rarely
1263 matters for well-written tests, but can create baffling symptoms if
1264 side effects from one test to the next affect outcomes. ``DocTestFinder``
1265 has been changed to sort the list of tests it returns.
1266
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001267- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001268 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001269
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001270- Bug #978833: Really close underlying socket in _socketobject.close.
1271
Georg Brandl8c036cc2006-08-20 13:15:39 +00001272- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1273 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001274
Georg Brandlcf0c1722006-07-26 07:23:32 +00001275- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1276 to recursive calls and call it with the failing package name.
1277
Martin v. Löwis0b483032006-07-25 09:53:12 +00001278- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1279
Georg Brandlc13c34c2006-07-24 14:09:56 +00001280- Patch #1515343: Fix printing of deprecated string exceptions with a
1281 value in the traceback module.
1282
Greg Ward48fae7a2006-07-23 16:05:51 +00001283- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1284
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001285- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1286
Brett Cannoncaebe222006-07-18 04:41:36 +00001287- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1288 argument tuple. For arguments where zero is illegal, the value is forced to
1289 the minimum value that is correct. This is to support an undocumented but
1290 common way people used to fill in inconsequential information in the time
1291 tuple pre-2.4.
1292
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001293- Patch #1220874: Update the binhex module for Mach-O.
1294
Barry Warsawb110bad2006-07-21 14:51:07 +00001295- The email package has improved RFC 2231 support, specifically for
1296 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1297 (name*0=<blah>) parameter continuations. This may change the types of
1298 values returned from email.message.Message.get_param() and friends.
1299 Specifically in some cases where non-encoded continuations were used,
1300 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1301 will just return the string (since non-encoded continuations don't have
1302 charset and language parts).
1303
1304 Also, whereas % values were decoded in all parameter continuations, they are
1305 now only decoded in encoded parameter parts.
1306
Ronald Oussoren3075e162006-07-25 20:28:55 +00001307- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1308
1309- Bug #1517996: IDLE now longer shows the default Tk menu when a
1310 path browser, class browser or debugger is the frontmost window on MacOS X
1311
Barry Warsaw00decd72006-07-27 23:43:15 +00001312- Patch #1520294: Support for getset and member descriptors in types.py,
1313 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1314 of an object against these built-in types and more importantly, for getting
1315 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001318Extension Modules
1319-----------------
1320
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001321- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1322 a socket operation on a socket with a timeout, the exception will be
1323 caught correctly. Previously, the exception was not caught.
1324
Thomas Heller1393d6a2006-07-28 21:43:20 +00001325- Patch #1529514: The _ctypes extension is now compiled on more
1326 openbsd target platforms.
1327
Tim Peters9cab5932006-07-28 00:30:00 +00001328- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1329 a memory leak, affecting pickles and deep copies.
1330
Tim Petersbc24eee2006-07-27 01:14:53 +00001331- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001332 Paul Eggert.
1333
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001334- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1335
Thomas Hellerce049a02006-07-14 17:51:14 +00001336- Patch #1521817: Index range checking on ctypes arrays containing
1337 exactly one element enabled again. This allows iterating over these
1338 arrays, without the need to check the array size before.
1339
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001340- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001341 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001342 /dev/null in certain cases; this is now fixed.
1343
Thomas Heller47d7a062006-07-12 08:43:47 +00001344- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1345 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001346
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001347- Because of a misspelled preprocessor symbol, ctypes was always
1348 compiled without thread support; this is now fixed.
1349
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001350- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1351 methods now allow their database parameter to be None as the
1352 sleepycat API allows.
1353
Matt Flemingec926502006-07-28 11:27:27 +00001354- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1355 bluetooth API compared with Linux and FreeBSD.
1356
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001357Tests
1358-----
1359
1360- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1361 how long the test file should take to play. Now accepts taking 2.93 secs
1362 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1363
Georg Brandl4793aa32006-07-28 18:31:39 +00001364- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1365 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1366 run via ``regrtest.py``. Now they do.

1375
1376- PythonLauncher now works correctly when the path to the script contains
1377 characters that are treated specially by the shell (such as quotes).
1378
1379- Bug #1527397: PythonLauncher now launches scripts with the working directory
1380 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001381 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001382 expect.

1392
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001393- Bug #1441486: The literal representation of -(sys.maxint - 1)
1394 again evaluates to a int object, not a long.
1395
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001396- Bug #1501934: The scope of global variables that are locally assigned
1397 using augmented assignment is now correctly determined.
1398
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001399- Bug #927248: Recursive method-wrapper objects can now safely
1400 be released.
1401
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001402- Bug #1417699: Reject locale-specific decimal point in float()
1403 and atof().
1404
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001405- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1406 omit a default "error" argument for NULL pointer. This allows
1407 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001408
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001409- Bug #1519018: 'as' is now validated properly in import statements.
1410
Neal Norwitz28746ab2006-07-09 22:14:42 +00001411- On 64 bit systems, int literals that use less than 64 bits are
1412 now ints rather than longs.
1413
Neal Norwitzed657552006-07-10 00:04:44 +00001414- Bug #1512814, Fix incorrect lineno's when code at module scope
1415 started after line 256.
1416
Tim Peters32a83612006-07-10 21:08:24 +00001417- New function ``sys._current_frames()`` returns a dict mapping thread
1418 id to topmost thread stack frame. This is for expert use, and is
1419 especially useful for debugging application deadlocks. The functionality
1420 was previously available in Fazal Majid's ``threadframe`` extension
1421 module, but it wasn't possible to do this in a wholly threadsafe way from
1422 an extension.

1429
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001430- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1431
Tim Peters32a83612006-07-10 21:08:24 +00001432- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001433 environment variable to be set in order to the SDK environment

1439
Thomas Woutersadd19112006-07-05 11:03:49 +00001440- string.Template() now correctly handles tuple-values. Previously,
1441 multi-value tuples would raise an exception and single-value tuples would
1442 be treated as the value they contain, instead.
1443
Martin v. Löwisede77f52006-07-03 13:01:35 +00001444- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1449
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001450- Bug #1514693: Update turtle's heading when switching between
1451 degrees and radians.
1452
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001453- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001454 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001455
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001456- Bug #1514703: Only setup canvas window in turtle when the canvas
1457 is created.
1458
Martin v. Löwis7596e832006-07-01 15:33:37 +00001459- Bug #1513223: .close() of a _socketobj now releases the underlying
1460 socket again, which then gets closed as it becomes unreferenced.
1461
Fred Drake10497c82006-06-29 02:57:48 +00001462- Bug #1504333: Make sgmllib support angle brackets in quoted
1463 attribute values.
1464
1465- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1466 sgmllib ('[' and ']' were not accepted).
1467

1469
Brett Cannon53ab5b72006-06-22 16:49:14 +00001470- Bug #1510580: The 'warnings' module improperly required that a Warning
1471 category be either a types.ClassType and a subclass of Warning. The proper
1472 check is just that it is a subclass with Warning as the documentation states.
1473
Georg Brandlad29e632006-06-21 17:45:17 +00001474- The compiler module now correctly compiles the new try-except-finally
1475 statement (bug #1509132).
1476
Neal Norwitz60373cd2006-06-22 06:30:50 +00001477- The wsgiref package is now installed properly on Unix.
1478

1480 shutdown when fileConfig() was called multiple times.
1481
Gerhard Häring762fbd32006-07-02 17:48:30 +00001482- The sqlite3 module did cut off data from the SQLite database at the first
1483 null character before sending it to a custom converter. This has been fixed
1484 now.
1485
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001486Extension Modules
1487-----------------
1488
Tim Peters112aad32006-07-19 00:03:19 +00001489- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1490 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1491 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001492
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001493- Assigning None to pointer type fields in ctypes structures possible
1494 overwrote the wrong fields, this is fixed now.
1495
1496- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1497 on non-Windows platforms.
1498
1499- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1500 integer or long, without range checking.
1501
1502- Patch #1517790: It is now possible to use custom objects in the ctypes
1503 foreign function argtypes sequence as long as they provide a from_param
1504 method, no longer is it required that the object is a ctypes type.
1505
1506- The '_ctypes' extension module now works when Python is configured
1507 with the --without-threads option.
1508
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001509- Bug #1513646: os.access on Windows now correctly determines write
1510 access, again.
1511
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001512- Bug #1512695: cPickle.loads could crash if it was interrupted with
1513 a KeyboardInterrupt.
1514
Neal Norwitza12aa882006-07-06 06:45:08 +00001515- Bug #1296433: parsing XML with a non-default encoding and
1516 a CharacterDataHandler could crash the interpreter in pyexpat.
1517

Martin v. Löwisd73168d2006-07-14 09:58:55 +00001523- Automate Windows build process for the Win64 SSL module.
1524
Tim Peters32a83612006-07-10 21:08:24 +00001525- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001526 Previously, the slight difference could cause compilation errors of the
1527 'zlib' module on systems with more than one version of zlib.
1528
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001529- The MSI compileall step was fixed to also support a TARGETDIR

Anthony Baxter51bcb682006-04-05 14:51:42 +00001559
1560Core and builtins
1561-----------------
1562
Georg Brandla56b9152006-06-19 06:35:54 +00001563- Patch #1507676: Error messages returned by invalid abstract object operations
1564 (such as iterating over an integer) have been improved and now include the
1565 type of the offending object to help with debugging.
1566
Brett Cannonea3912b2006-06-13 21:46:41 +00001567- Bug #992017: A classic class that defined a __coerce__() method that returned
1568 its arguments swapped would infinitely recurse and segfault the interpreter.
1569
Neal Norwitz909eb122006-06-12 02:13:21 +00001570- Fix the socket tests so they can be run concurrently.
1571
Neal Norwitzb9845e72006-06-12 02:11:18 +00001572- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001573 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001574
Brett Cannon22565aa2006-06-09 22:31:23 +00001575- Bug #532646: object.__call__() will continue looking for the __call__
1576 attribute on objects until one without one is found. This leads to recursion
1577 when you take a class and set its __call__ attribute to an instance of the
1578 class. Originally fixed for classic classes, but this fix is for new-style.
1579 Removes the infinite_rec_3 crasher.
1580
Georg Brandl24250812006-06-09 18:45:48 +00001581- The string and unicode methods startswith() and endswith() now accept
1582 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1583
Brett Cannonde3b0522006-06-08 17:00:45 +00001584- Buffer objects, at the C level, never used the char buffer
1585 implementation even when the char buffer for the wrapped object was
1586 explicitly requested (originally returned the read or write buffer).
1587 Now a TypeError is raised if the char buffer is not present but is
1588 requested.
1589
Georg Brandlddbaa662006-06-04 21:56:52 +00001590- Patch #1346214: Statements like "if 0: suite" are now again optimized
1591 away like they were in Python 2.4.
1592
Georg Brandlb7c8f542006-05-27 12:30:25 +00001593- Builtin exceptions are now full-blown new-style classes instead of
1594 instances pretending to be classes, which speeds up exception handling
1595 by about 80% in comparison to 2.5a2.
1596
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001597- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1598 Unicode 4.1.
1599
Georg Brandlf4ef1162006-05-26 18:03:31 +00001600- Patch #921466: sys.path_importer_cache is now used to cache valid and
1601 invalid file paths for the built-in import machinery which leads to
1602 fewer open calls on startup.
1603
Tim Peters696cf432006-05-24 21:10:40 +00001604- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1605 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1606 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1607 the number of input digits (it was and remains linear-time for bases
1608 2, 4, 8, 16 and 32).
1609
Tim Petersb713ec22006-05-23 18:45:30 +00001610- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1611 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1612 an integer close to ``sys.maxint``. This was repaired by patch
1613 #1335972, which also gives a nice speedup.
1614
Richard Jonescebbefc2006-05-23 18:28:17 +00001615- Patch #1337051: reduced size of frame objects.
1616
1617- PyErr_NewException now accepts a tuple of base classes as its
1618 "base" parameter.
1619
Richard Jones7c88dcc2006-05-23 10:37:38 +00001620- Patch #876206: function call speedup by retaining allocated frame
1621 objects.
1622
Georg Brandl7b90e162006-05-18 07:01:27 +00001623- Bug #1462152: file() now checks more thoroughly for invalid mode
1624 strings and removes a possible "U" before passing the mode to the
1625 C library function.
1626
Neal Norwitz1004a532006-05-15 07:17:23 +00001627- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1628
Neal Norwitz373f0a72006-05-15 07:04:36 +00001629- Bug #1487966: Fix SystemError with conditional expression in assignment
1630
Martin v. Löwis879768d2006-05-11 13:28:43 +00001631- WindowsError now has two error code attributes: errno, which carries
1632 the error values from errno.h, and winerror, which carries the error
1633 values from winerror.h. Previous versions put the winerror.h values
1634 (from GetLastError()) into the errno attribute.
1635
Martin v. Löwis77736712006-05-04 05:51:03 +00001636- Patch #1475845: Raise IndentationError for unexpected indent.
1637
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001638- Patch #1479181: split open() and file() from being aliases for each other.
1639
Tim Peters44bd9862006-06-01 13:49:23 +00001640- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1641 methods were always silently ignored by dictionaries when comparing keys.
1642 They are now passed through (except when using the C API function
1643 ``PyDict_GetItem()``, whose semantics did not change).
1644
1645- Bug #1456209: In some obscure cases it was possible for a class with a
1646 custom ``__eq__()`` method to confuse dict internals when class instances
1647 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1648 No, you don't have any code that did this ;-)

1656
Brett Cannon6ee7d012006-06-08 16:23:04 +00001657- Change binascii.hexlify to accept a read-only buffer instead of only a char
1658 buffer and actually follow its documentation.
1659
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001660- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1661
Nick Coghlanc649ec52006-05-29 12:43:05 +00001662- Patch #1478788 (modified version): The functional extension module has
1663 been renamed to _functools and a functools Python wrapper module added.
1664 This provides a home for additional function related utilities that are
1665 not specifically about functional programming. See PEP 309.
1666
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001667- Patch #1493701: performance enhancements for struct module.

1675 enabled builds on Windows and systems with Posix threads support.
1676
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001677- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1678 (up to the system limit of 32K characters).
1679
1680- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1681 As a result, these functions now raise WindowsError instead of OSError.
1682
Tim Peters7a822da2006-05-25 21:50:17 +00001683- ``time.clock()`` on Win64 should use the high-performance Windows
1684 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1685 Windows platforms).
1686
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001687- Calling Tk_Init twice is refused if the first call failed as that
1688 may deadlock.
1689
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001690- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1691 accept it without potentially using an uninitialized pointer.
1692
1693- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1694 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1695 patch numbers 1494885 and 1494902]

1702
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001703- bsddb: the __len__ method of a DB object has been fixed to return correct
1704 results. It could previously incorrectly return 0 in some cases.
1705 Fixes SF bug 1493322 (pybsddb bug 1184012).
1706
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001707- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1708 aborts the db transaction safely when a modifier callback fails.
1709 Fixes SF python patch/bug #1408584.
1710
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001711- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001712 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001713 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1714 database calls that would previously deadlock. [SF python bug #775414]
1715

Martin v. Löwisd8251432006-06-14 05:21:04 +00001743- Patch #1455898: The MBCS codec now supports the incremental mode for
1744 double-byte encodings.
1745
Tim Peters43898b42006-06-14 04:09:25 +00001746- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1747 guarantee that adjacent triples in the return list always describe
1748 non-adjacent blocks. Previously, a pair of matching blocks could end
1749 up being described by multiple adjacent triples that formed a partition
1750 of the matching pair.
1751
Greg Ward0e0c9f42006-06-11 16:24:11 +00001752- Bug #1498146: fix optparse to handle Unicode strings in option help,
1753 description, and epilog.
1754
Greg Wardd1c797e2006-06-11 14:42:41 +00001755- Bug #1366250: minor optparse documentation error.
1756
Greg Ward7f547402006-06-11 00:40:49 +00001757- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1758 clarify docs.
1759
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001760- The wsgiref package has been added to the standard library.
1761
Nick Coghlan676725d2006-06-08 13:54:49 +00001762- The functions update_wrapper() and wraps() have been added to the functools
1763 module. These make it easier to copy relevant metadata from the original
1764 function when writing wrapper functions.
1765
Tim Petersd6a9eef2006-06-05 01:48:21 +00001766- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1767 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001768
Martin v. Löwis3f767792006-06-04 19:36:28 +00001769- Patch #1359618: Speed up charmap encoder by using a trie structure
1770 for lookup.
1771
Tim Petersd609b1a2006-06-02 23:22:51 +00001772- The functions in the ``pprint`` module now sort dictionaries by key
1773 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1774 if and only if its display required more than one line, although that
1775 wasn't documented. The new behavior increases predictability; e.g.,
1776 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1777
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001778- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1779 (thanks for J. J. Lee).
1780
Georg Brandl2b330372006-05-28 20:23:12 +00001781- Patch #1496206: improve urllib2 handling of passwords with respect to
1782 default HTTP and HTTPS ports.
1783
George Yoshidaf3c65de2006-05-28 16:39:09 +00001784- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1785
Bob Ippolito7298f272006-05-23 18:43:47 +00001786- Patch #1281707: speed up gzip.readline.
1787
Georg Brandlb89316f2006-05-17 15:51:16 +00001788- Patch #1180296: Two new functions were added to the locale module:
1789 format_string() to get the effect of "format % items" but locale-aware,
1790 and currency() to format a monetary number with currency sign.
1791
Georg Brandle3a25832006-05-17 14:56:04 +00001792- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1793 and several features added, such as speed and geometry control.
1794
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001795- Patch #1488881: add support for external file objects in bz2 compressed
1796 tarfiles.
1797
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001798- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1799 stdout arguments, making it possible to redirect input and output
1800 for remote debugging.
1801
1802- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1803 a couple of issues, notably handling of long file names using the
1804 GNU LONGNAME extension.
1805
1806- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1807 new flag when ``name`` is already the name of an option flag.
1808
1809- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1810 package.
1811
1812- Patch #1472854: make the rlcompleter.Completer class usable on non-
1813 UNIX platforms.
1814
1815- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1816
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001817- Bug #1472827: correctly escape newlines and tabs in attribute values in
1818 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001848What's New in Python 2.5 alpha 2?
1849=================================
1850
1851*Release date: 27-APR-2006*
1852
1853Core and builtins
1854-----------------
1855
Thomas Heller1b046642006-04-18 18:51:06 +00001856- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1857 by converting these apis from macros into exported functions again:
1858
1859 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1860 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1861 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1862 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1863 PyRun_String Py_CompileString
1864
Martin v. Löwis45294a92006-04-18 06:24:08 +00001865- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1866
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001867- All uses of PyStructSequence_InitType have been changed to initialize
1868 the type objects only once, even if the interpreter is initialized
1869 multiple times.
1870
Neal Norwitz61546162006-04-14 05:20:28 +00001871- Bug #1454485, array.array('u') could crash the interpreter. This was
1872 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1873 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1874
1875- Py_UNICODE is unsigned. It was always documented as unsigned, but
1876 due to a bug had a signed value in previous versions.
1877
Tim Peters3a5e8b12006-04-11 01:44:07 +00001878- Patch #837242: ``id()`` of any Python object always gives a positive
1879 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1880 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001881 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001882 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001883
Tim Peters3a5e8b12006-04-11 01:44:07 +00001884 def __hash__(self):
1885 return id(self) # WRONG
1886
1887 because a hash result must be a (short) Python int but it was always
1888 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001889 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001890 was always usable as a hash value before this patch. That's no longer
1891 necessarily so.
1892
1893- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001894 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001895 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001896 #1454844)
1897
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001898- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1899 involving generators that have paused outside of any ``try`` or ``with``
1900 blocks. (In 2.5a1, a paused generator that was part of a reference
1901 cycle could not be garbage collected, regardless of whether it was
1902 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001903
Anthony Baxter51bcb682006-04-05 14:51:42 +00001904Extension Modules

1909
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001910- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1911 fails with an error condition.
1912
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001913- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1914
1915- Bug #1117761: bsddb.*open() no longer raises an exception when using
1916 the cachesize parameter.
1917
1918- Bug #1149413: bsddb.*open() no longer raises an exception when using
1919 a temporary db (file=None) with the 'n' flag to truncate on open.
1920
1921- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1922 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001923
Armin Rigoa9017c32006-04-19 11:50:27 +00001924- Patch #1062014: AF_UNIX sockets under Linux have a special
1925 abstract namespace that is now fully supported.

1931 of the process using the returncode attribute, instead of
1932 abusing errno.
1933
Tim Peters711bf302006-04-25 03:31:36 +00001934- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1935 a doctest to be skipped (the code is not run, and the expected output
1936 or exception is ignored).
1937
Nick Coghlanda2268f2006-04-24 04:37:15 +00001938- Fixed contextlib.nested to cope with exceptions being raised and
1939 caught inside exit handlers.
1940
Greg Wardab05edc2006-04-23 03:47:58 +00001941- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1942 hex, octal, or binary; add ``append_const`` action; keep going if
1943 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1944 added ``epilog`` for better help generation).
1945
Tim Peters21fbd572006-04-21 21:18:10 +00001946- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1947 called from a thread spawned as a side effect of importing a module.
1948
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001949- The pydoc module now supports documenting packages contained in
1950 .zip or .egg files.
1951
1952- The pkgutil module now has several new utility functions, such
1953 as ``walk_packages()`` to support working with packages that are either
1954 in the filesystem or zip files.
1955
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001956- The mailbox module can now modify and delete messages from
1957 mailboxes, in addition to simply reading them. Thanks to Gregory
1958 K. Johnson for writing the code, and to the 2005 Google Summer of
1959 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001960
Tim Petersc7605f22006-04-17 21:12:33 +00001961- The ``__del__`` method of class ``local`` in module ``_threading_local``
1962 returned before accomplishing any of its intended cleanup.
1963
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001964- Patch #790710: Add breakpoint command lists in pdb.
1965

1969
Anthony Baxtere29002c2006-04-12 12:07:31 +00001970- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1971 Windows. Bug #1469163.
1972
Phillip J. Eby47032112006-04-11 01:07:43 +00001973- The warnings, linecache, inspect, traceback, site, and doctest modules
1974 were updated to work correctly with modules imported from zipfiles or
1975 via other PEP 302 __loader__ objects.
1976
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001977- Patch #1467770: Reduce usage of subprocess._active to processes which

1989
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001990- The Makefile now has a reindent target, which runs reindent.py on
1991 the library.
1992

1998 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001999 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002000 CXX from --with-cxx-main, see description in README.
2001

2005
Tim Peters8931ff12006-05-13 23:28:20 +00002006- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2007 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2008 and "%zu" for unsigned integers of type ``size_t``.
2009
Anthony Baxter51bcb682006-04-05 14:51:42 +00002010Tests
2011-----
2012
Nick Coghlanda2268f2006-04-24 04:37:15 +00002013- test_contextlib now checks contextlib.nested can cope with exceptions
2014 being raised and caught inside exit handlers.
2015
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002016- test_cmd_line now checks operation of the -m and -c command switches
2017
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002018- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2019 it separately and by hand. It also wasn't cleaning up its changes to
2020 the current Decimal context.
2021
Thomas Woutersabd08882006-04-26 15:53:30 +00002022- regrtest.py now has a -M option to run tests that test the new limits of
2023 containers, on 64-bit architectures. Running these tests is only sensible
2024 on 64-bit machines with more than two gigabytes of memory. The argument
2025 passed is the maximum amount of memory for the tests to use.

2055 allowing it to support modules in packages and zipfiles
2056
Martin v. Löwisc661b882006-04-20 04:54:23 +00002057- On Windows, .DLL is not an accepted file name extension for
2058 extension modules anymore; extensions are only found if they
2059 end in .PYD.
2060
Martin v. Löwisea62d252006-04-03 10:56:49 +00002061- Bug #1421664: sys.stderr.encoding is now set to the same value as
2062 sys.stdout.encoding.
2063
Neal Norwitz92e212f2006-04-03 04:48:37 +00002064- __import__ accepts keyword arguments.
2065
Georg Brandlccadf842006-03-31 18:54:53 +00002066- Patch #1460496: round() now accepts keyword arguments.
2067
Anthony Baxter262c00a2006-03-30 10:53:17 +00002068- Fixed bug #1459029 - unicode reprs were double-escaped.
2069
Hye-Shik Changd478f342006-03-23 12:32:36 +00002070- Patch #1396919: The system scope threads are reenabled on FreeBSD
2071 5.4 and later versions.
2072
Neal Norwitze98ccf62006-03-23 05:39:47 +00002073- Bug #1115379: Compiling a Unicode string with an encoding declaration
2074 now gives a SyntaxError.
2075
Georg Brandlabd1ff82006-03-18 07:59:59 +00002076- Previously, Python code had no easy way to access the contents of a
2077 cell object. Now, a ``cell_contents`` attribute has been added
2078 (closes patch #1170323).
2079
Tim Peterscf79aac2006-03-16 01:14:46 +00002080- Patch #1123430: Python's small-object allocator now returns an arena to
2081 the system ``free()`` when all memory within an arena becomes unused
2082 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2083 freed. Some applications will see a drop in virtual memory size now,
2084 especially long-running applications that, from time to time, temporarily
2085 use a large number of small objects. Note that when Python returns an
2086 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002087 platform C library will in turn return that memory to the operating system.
2088 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002089 appears to be effective at least on Microsoft C and gcc-based systems.
2090 Thanks to Evan Jones for hard work and patience.
2091
Georg Brandl533ff6f2006-03-08 18:09:27 +00002092- Patch #1434038: property() now uses the getter's docstring if there is
2093 no "doc" argument given. This makes it possible to legitimately use
2094 property() as a decorator to produce a read-only property.
2095
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002096- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2097 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2098 of requiring an int or long in slicing and a few other contexts, enabling
2099 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2100
Neal Norwitz995acdf2006-03-07 05:01:00 +00002101- Fixed various bugs reported by Coverity's Prevent tool.
2102
Brett Cannonbf364092006-03-01 04:25:17 +00002103- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2104 new exception base class, BaseException, which has a new message attribute.
2105 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2106 Raising a string exception now raises a DeprecationWarning.
2107
Thomas Woutersfb609f42006-02-28 16:37:25 +00002108- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2109 explicitly relative, using 'from .module import name' to mean 'from the same
2110 package as this module is in. Imports without dots still default to the
2111 old relative-then-absolute, unless 'from __future__ import
2112 absolute_import' is used.
2113
Brett Cannona7446e32006-02-27 23:39:10 +00002114- Properly check if 'warnings' raises an exception (usually when a filter set
2115 to "error" is triggered) when raising a warning for raising string
2116 exceptions.
2117
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002118- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002119 The name was removed from Include/code.h.
2120
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002121- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002122
Guido van Rossum1968ad32006-02-25 22:38:04 +00002123- Patch 1433928:
2124 - The copy module now "copies" function objects (as atomic objects).
2125 - dict.__getitem__ now looks for a __missing__ hook before raising
2126 KeyError.
2127
Tim Peters84ef21c2006-02-28 20:39:06 +00002128- PEP 343: with statement implemented. Needs ``from __future__ import
2129 with_statement``. Use of 'with' as a variable will generate a warning.
2130 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002131 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002132 The following objects have __context__ methods:
2133 - The built-in file type.
2134 - The thread.LockType type.
2135 - The following types defined by the threading module:
2136 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2137 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002138
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002139- Fix the encodings package codec search function to only search
2140 inside its own package. Fixes problem reported in patch #1433198.
2141
2142 Note: Codec packages should implement and register their own
2143 codec search function. PEP 100 has the details.
2144
Tim Peters9ea89d22006-06-04 03:26:02 +00002145- PEP 353: Using ``Py_ssize_t`` as the index type.
2146
2147- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2148 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2149 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2150 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2151 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002152
Neal Norwitzfc76d632006-01-10 06:03:13 +00002153- Patch #1400181, fix unicode string formatting to not use the locale.
2154 This is how string objects work. u'%f' could use , instead of .
2155 for the decimal point. Now both strings and unicode always use periods.
2156
Neal Norwitz671b9e32006-01-09 07:07:12 +00002157- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2158 configure would break checking curses.h.
2159
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002160- Bug #959576: The pwd module is now builtin. This allows Python to be
2161 built on UNIX platforms without $HOME set.
2162
Neal Norwitzc10978f2005-12-19 06:07:16 +00002163- Bug #1072182, fix some potential problems if characters are signed.
2164
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002165- Bug #889500, fix line number on SyntaxWarning for global declarations.
2166
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002167- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2168
Neal Norwitze7214a12005-12-18 05:03:17 +00002169- Support for converting hex strings to floats no longer works.
2170 This was not portable. float('0x3') now raises a ValueError.
2171
Barry Warsaw2a38a862005-12-18 01:27:35 +00002172- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002173 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002174 is now displayed in interactive prompt banner.
2175
Georg Brandlfa166682005-12-17 21:45:17 +00002176- Implementation of PEP 341 - Unification of try/except and try/finally.
2177 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002178 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002179
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002180- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2181 now encodes backslash correctly.
2182
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002183- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2184
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002185- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002186 and long longs.
2187
Neal Norwitz67715f02005-11-09 06:59:35 +00002188- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002189 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002190 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002191
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002192- Replaced most Unicode charmap codecs with new ones using the
2193 new Unicode translate string feature in the builtin charmap
2194 codec; the codecs were created from the mapping tables available
2195 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2196 encodings now include a mapping for the Apple logo)
2197
Tim Peterse3547fd2005-12-16 23:13:57 +00002198- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002199
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002200- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002201
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002202- A new AST parser implementation was completed. The abstract
2203 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002204 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002205
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002206- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002207 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2208
Neal Norwitz708e51a2005-10-03 04:48:15 +00002209- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2210
Neal Norwitz11bd1192005-10-03 00:54:56 +00002211- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2212 Provide a warning when a directory is passed on the command line.
2213
Neal Norwitz40d37812005-10-02 01:48:49 +00002214- Fix segfault with invalid coding.
2215
2216- SF bug #772896: unknown encoding results in MemoryError.
2217
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002218- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002219 supported a __len__() method which evaluated to False when the iterator
2220 was empty.
2221
Guido van Rossum630db602005-09-20 18:49:54 +00002222- On 64-bit platforms, when __len__() returns a value that cannot be
2223 represented as a C int, raise OverflowError.
2224
Skip Montanarof8948ca2005-09-19 03:54:46 +00002225- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002226 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002227
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002228- SF bug #893549: parsing keyword arguments was broken with a few format
2229 codes.
2230
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002231- Changes donated by Elemental Security to make it work on AIX 5.3
2232 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2233 bug #105470: test_pwd fails on 64bit system (Opteron).
2234
Guido van Rossum539c6622005-09-14 17:49:54 +00002235- Changes donated by Elemental Security to make it work on HP-UX 11 on
2236 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2237
Georg Brandl4550b8d2005-08-26 06:43:52 +00002238- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002239 (fixes bug #1119418).
2240
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002241- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2242
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002243- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2244 exceptions that cause a function to exit.
2245
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002246- The implementation of set() and frozenset() was revised to use its
2247 own internal data structure. Memory consumption is reduced by 1/3
2248 and there are modest speed-ups as well. The API is unchanged.
2249
Tim Petersde7990b2005-07-17 23:45:23 +00002250- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2251
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002252- SF bug #1229429: PyObject_CallMethod failed to decrement some
2253 reference counts in some error exit cases.
2254
Tim Petersecc6e6a2005-07-10 22:30:55 +00002255- SF bug #1185883: Python's small-object memory allocator took over
2256 a block managed by the platform C library whenever a realloc specified
2257 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002258 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002259 portable way to copy data from the C-managed block into Python's
2260 small-object space without risking a memory fault. Python's small-object
2261 realloc now leaves such blocks under the control of the platform C
2262 realloc.
2263
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002264- SF bug #1232517: An overflow error was not detected properly when
2265 attempting to convert a large float to an int in os.utime().
2266
Raymond Hettinger3296e692005-06-29 23:29:56 +00002267- SF bug #1224347: hex longs now print with lowercase letters just
2268 like their int counterparts.
2269
Michael W. Hudson188d4362005-06-20 16:52:57 +00002270- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2271 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2272 interpreter states; back out that fix and do a better job (see
2273 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2274 for a longer write-up of the problem).
2275
Michael W. Hudsondf888462005-06-03 14:41:55 +00002276- SF patch #1180995: marshal now uses a binary format by default when
2277 serializing floats.
2278
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002279- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2280 the routines that promise to produce IEEE 754 binary representations
2281 of floats now simply copy bytes around.
2282
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002283- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2284 278.
2285
Brett Cannonc3647ac2005-04-26 03:45:26 +00002286- patch #1109424: int, long, float, complex, and unicode now check for the
2287 proper magic slot for type conversions when subclassed. Previously the
2288 magic slot was ignored during conversion. Semantics now match the way
2289 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002290 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002291 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002292 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002293
Barry Warsawc8d907c2005-04-19 23:43:40 +00002294- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2295 NULL, now raise an AttributeError when attempting to set or delete the
2296 attribute. Previously a TypeError was raised, but this was inconsistent
2297 with the equivalent pure-Python implementation.
2298
Michael W. Hudson774479c2005-04-18 08:46:17 +00002299- It is now safe to call PyGILState_Release() before
2300 PyEval_InitThreads() (note that if there is reason to believe there
2301 are multiple threads around you still must call PyEval_InitThreads()
2302 before using the Python API; this fix is for extension modules that
2303 have no way of knowing if Python is multi-threaded yet).
2304
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002305- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2306 disabled caused a crash.
2307
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002308- Bug #1165306: instancemethod_new allowed the creation of a method
2309 with im_class == im_self == NULL, which caused a crash when called.
2310
Tim Petersecc6e6a2005-07-10 22:30:55 +00002311- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002312 fixes the crash seen in bug #1165761
2313
Raymond Hettinger96229b12005-03-11 06:49:40 +00002314- Added two new builtins, any() and all().
2315
Brett Cannon409d8f22005-03-05 06:47:57 +00002316- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002317 (e.g., ``class C(): pass`` is no longer a syntax error).

2357 current thread state when the auto-GIL-state machinery knows about
2358 it (since the thread state is being deleted, continuing to remember it
2359 can't help, but can hurt if another thread happens to get created with
2360 the same thread id).

Nick Coghlan43832302006-04-23 17:04:07 +00002556- PEP 338: new module runpy defines a run_module function to support
2557 executing modules which provide access to source code or a code object
2558 via the PEP 302 import mechanisms.
2559

2568 in attribute values.
2569
Anthony Baxterc51ee692006-04-01 00:57:31 +00002570- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002571 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002572 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002573 module will not be built.
2574
Tim Petersc17976e2006-04-01 00:26:53 +00002575- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2576 aren't officially supported here, and trying to use them will probably

2598
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002599- email 4.0 package now integrated. This is largely the same as the email 3.0
2600 package that was included in Python 2.3, except that PEP 8 module names are
2601 now used (e.g. mail.message instead of email.Message). The MIME classes
2602 have been moved to a subpackage (e.g. email.mime.text instead of
2603 email.MIMEText). The old names are still supported for now. Several
2604 deprecated Message methods have been removed and lots of bugs have been
2605 fixed. More details can be found in the email package documentation.

2608 (a subclass of tuple) that provides incremental decoders and encoders
2609 (a way to use stateful codecs without the stream API). Python functions
2610 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2611 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2612 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002613

2615 a ValueError instead of a StopIteration now (like file and cString.String do).
2616 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2617 called before (like file and StringIO.StringIO do).

Tim Peterse3547fd2005-12-16 23:13:57 +00002691 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2692 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2693 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2694 Ronald L. Rivest offered this advice for Python:
2695
2696 "The consensus of researchers in this area (at least as
2697 expressed at the NIST Hash Function Workshop 10/31/05),
2698 is that SHA-256 is a good choice for the time being, but
2699 that research should continue, and other alternatives may
2700 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002701
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002702- Added a subset of Fredrik Lundh's ElementTree package. Available

2860
Guido van Rossumd0641422005-02-03 15:01:24 +00002861- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2862 disables recursive traversal through instance attributes, which can
2863 be exploited in various ways.
2864
Tim Peterse3547fd2005-12-16 23:13:57 +00002865- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002866 flags on the HTTP listening socket.
2867
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002868- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2869 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2870
Fred Drakefbdeaad2006-07-29 16:56:15 +00002871- Patches #893642, #1039083: add allow_none, encoding arguments to
2872 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.

2877
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002878- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2879
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002880- Enhancements to the csv module:
2881
2882 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002883 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002884 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002885 + Dialect parameter parsing has been re-implemented to improve error
2886 reporting.
2887 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2888 dictates.
2889 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002890 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002891 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002892 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2893 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002894 + reader now allows \r characters to be quoted (previously it only allowed
2895 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002896 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002897 + Dialect classes passed to the module are no longer instantiated by
2898 the module before being parsed (the former validation scheme required
2899 this, but the mechanism was unreliable).
2900 + The dialect registry now contains instances of the internal
2901 C-coded dialect type, rather than references to python objects.
2902 + the internal c-coded dialect type is now immutable.
2903 + register_dialect now accepts the same keyword dialect specifications
2904 as the reader and writer, allowing the user to register dialects
2905 without first creating a dialect class.
2906 + a configurable limit to the size of parsed fields has been added -
2907 previously, an unmatched quote character could result in the entire
2908 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002909 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002910 the parser field size limit (returning the former limit). The initial
2911 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002912 + A line_num attribute has been added to the reader object, which tracks
2913 the number of lines read from the source iterator. This is not
2914 the same as the number of records returned, as records can span
2915 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002916 + reader and writer objects were not being registered with the cyclic-GC.
2917 This has been fixed.
2918
Brett Cannone6539c42005-01-08 02:43:53 +00002919- _DummyThread objects in the threading module now delete self.__block that is
2920 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2921 lock primitives tend to be limited in number and thus should not be wasted on
2922 a _DummyThread object. Fixes bug #1089632.
2923
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002924- The imghdr module now detects Exif files.
2925
Raymond Hettinger6065d322004-12-20 23:51:53 +00002926- StringIO.truncate() now correctly adjusts the size attribute.
2927 (Bug #951915).
2928
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002929- locale.py now uses an updated locale alias table (built using
2930 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2931 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002932 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002933
Raymond Hettinger3557f422004-12-07 12:02:02 +00002934- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2935
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002936- the pickle module no longer accepts the deprecated None option in the
2937 args tuple returned by __reduce__().
2938
Brett Cannon84667c02004-12-07 03:25:18 +00002939- optparse now optionally imports gettext. This allows its use in setup.py.
2940
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002941- the pickle module no longer uses the deprecated bin parameter.
2942
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002943- the shelve module no longer uses the deprecated binary parameter.
2944
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002945- the pstats module no longer uses the deprecated ignore() method.
2946
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002947- the filecmp module no longer uses the deprecated use_statcache argument.
2948
Raymond Hettinger664347b2004-12-04 21:21:53 +00002949- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2950 extended or overridden by subclasses. Formerly, the subclassed method would
2951 be ignored by the rest of the module. (Bug #1078905).
2952
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002953- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002954 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002955
Walter Dörwald36733692004-12-22 12:50:50 +00002956- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2957 once when a size argument is given. This prevents a buffer overflow in the
2958 tokenizer with very long source lines.
2959
Barry Warsaw538561e2006-01-01 21:48:54 +00002960- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2961 immediately after creating the object, without any intervening
2962 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002963
Skip Montanaro05885812005-01-16 20:48:27 +00002964- The reconvert.quote function can now emit triple-quoted strings. The
2965 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002966
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002967- ``UserString.MutableString`` now supports negative indices in
2968 ``__setitem__`` and ``__delitem__``
2969
Greg Ward40407942005-03-05 02:53:17 +00002970- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2971 correctly.
2972
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002973- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2974 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2975 character even if the user has passed a size parameter to get a proper
2976 line ending. Remove the special handling of a "\r\n" that has been split
2977 between two lines.
2978
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002979- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2980 about illegal code points. The codec now supports PEP 293 style error
2981 handlers.
2982
Walter Dörwald78a78b02005-09-01 12:04:29 +00002983- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002984 from the input stream, so that the output is a byte string in the correct
2985 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002986
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002987- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2988 considering it exactly like a '*'.
2989
Walter Dörwald007f8df2005-10-09 19:42:27 +00002990- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2991 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002992
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002993- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2994
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002995- Patch #1413711: Certain patterns of differences were making difflib
2996 touch the recursion limit.
2997
Walter Dörwald58917a62006-03-31 15:26:22 +00002998- Bug #947906: An object oriented interface has been added to the calendar
2999 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003000 called as a script (e.g. via ``python -mcalendar``). Localized month and
3001 weekday names can be ouput (even if an exotic encoding is used) using
3002 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003003
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003004Build

3011
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003012- Build support for Win64-AMD64 was added.
3013
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003014- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3015
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003016- Patch #881820: look for openpty and forkpty also in libbsd.
3017
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003018- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3019 The zlib module is now builtin on Windows.
3020
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003021- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3022
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003023- Bug #1189330: configure did not correctly determine the necessary
3024 value of LINKCC if python was built with GCC 4.0.
3025
Trent Mick8321b422005-07-26 02:29:21 +00003026- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3027 vulnerability in zlib 1.2.1 and 1.2.2.
3028
Brett Cannon08cd5982005-04-24 22:26:38 +00003029- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3030 flags that change binary compatibility. Changes were also made to
3031 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003032 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003033
Bob Ippolitoed233462005-03-29 13:47:59 +00003034- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3035 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3036 no longer exists). This configure patch makes things right.
3037
Martin v. Löwise2713be2005-03-08 15:03:08 +00003038- Bug #1158607: Build with --disable-unicode again.
3039
Brett Cannon46d96232005-02-16 00:07:19 +00003040- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3041 defined. Discovered as a result of not being able to build on OS X.
3042
Brett Cannon516592f2004-12-07 00:42:59 +00003043- setup.py now uses the directories specified in LDFLAGS using the -L option
3044 and in CPPFLAGS using the -I option for adding library and include
3045 directories, respectively, for compiling extension modules against. This has
3046 led to the core being compiled using the values in CPPFLAGS. It also removes
3047 the need for the special-casing of both DarwinPorts and Fink for darwin since
3048 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3049 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3050 Fink, ``-I/opt/local/include`` for DarwinPorts).
3051
Brett Cannon43802422005-02-10 20:48:03 +00003052- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3053 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3054 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3055 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003057C API
3058-----
3059
Tim Petersc9d78aa2006-03-26 23:27:58 +00003060- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3061 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3062 is obtained via the ``PyObject_`` family, it must be released via the
3063 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3064 always been officially true, but when Python's small-object allocator was
3065 introduced, an attempt was made to cater to a few extension modules
3066 discovered at the time that obtained memory via ``PyObject_New`` but
3067 released it via ``PyMem_DEL``. It's years later, and if such code still
3068 exists it will fail now (probably with segfaults, but calling wrong
3069 low-level memory management functions can yield many symptoms).
3070
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003071- Added a C API for set and frozenset objects.
3072

3074
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003075- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3076 mapping argument now. This string is used as a mapping table. Byte values
3077 greater than the length of the string and 0xFFFE are treated as undefined
3078 mappings.
