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

168 again, no longer the posix error code.
169
Martin v. Löwisb5bc5372006-10-27 06:16:31 +0000170- Patch #1549049: Support long values in structmember, issue warnings

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

352 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +0000353 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +0000354

367 GNOME or KDE browser, depending on whether there is a session of one
368 of those present. Also, it tries the Windows default browser before

370

Collin Winterfaaa2042007-03-10 03:35:34 +0000442 be equal to calling getsockname() on the server's socket. Fixed by
443 patch #1545011.
Collin Winter22c42ba2007-03-10 02:51:26 +0000444

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

496 import semantics.

1009
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001010- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001011 compared equal or unequal to a string and a UnicodeDecodeError
1012 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001013
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001014 Instead, the equal (==) and unequal (!=) comparison operators will
1015 now issue a UnicodeWarning and interpret the two objects as
1016 unequal. The UnicodeWarning can be filtered as desired using
1017 the warning framework, e.g. silenced completely, turned into an
1018 exception, logged, etc.
1019
1020 Note that compare operators other than equal and unequal will still
1021 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001022
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001023- Fix segfault when doing string formatting on subclasses of long.
1024
1025- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1026 with new-style classes.
1027
1028- Fix bug related to __len__ functions returning negative values with
1029 classic classes.
1030
1031- Patch #1538606, Fix __index__() clipping. There were some problems
1032 discovered with the API and how integers that didn't fit into Py_ssize_t
1033 were handled. This patch attempts to provide enough alternatives
1034 to effectively use __index__.
1035
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001036- Bug #1536021: __hash__ may now return long int; the final hash
1037 value is obtained by invoking hash on the long int.
1038
Thomas Hellerab1049c2006-08-08 17:37:00 +00001039- Bug #1536786: buffer comparison could emit a RuntimeWarning.

1043
Thomas Heller74d36f02006-08-04 18:17:40 +00001044- On Windows, the PyErr_Warn function is now exported from
1045 the Python dll again.
1046
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001047- Bug #1191458: tracing over for loops now produces a line event
1048 on each iteration. Fixing this problem required changing the .pyc
1049 magic number. This means that .pyc files generated before 2.5c1
1050 will be regenerated.
1051
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001052- Bug #1333982: string/number constants were inappropriately stored
1053 in the byte code and co_consts even if they were not used, ie
1054 immediately popped off the stack.
1055
Georg Brandle9462c72006-08-04 18:03:37 +00001056- Fixed a reference-counting problem in property().

1063 generated for generator expressions.
1064
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001065- The distutils version has been changed to 2.5.0. The change to
1066 keep it programmatically in sync with the Python version running
1067 the code (introduced in 2.5b3) has been reverted. It will continue
1068 to be maintained manually as static string literal.
1069
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001070- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001071 and this cannot be converted to the required C type, an exception is
1072 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001073 callback returned arbitrary values to the calling code.

1077
Tim Petersc10c9d02006-09-05 02:18:09 +00001078- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001079 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001080 workarounds for clocks with low resolution, to stop the code yielding
1081 duplicate UUIDs.
1082
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001083- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1084 before raising SystemExit, allowing IDLE to honor quit() and exit().
1085
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001086- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.

1113
Thomas Heller86720042006-08-14 11:17:48 +00001114- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1115 uses the _as_parameter_ attribute when objects are passed to foreign
1116 function calls. The ctypes version number was changed to 1.0.1.
1117
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001118- Bug #1530559, struct.pack raises TypeError where it used to convert.

Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001176- Bug #1515471: string.replace() accepts character buffers again.
1177
Neal Norwitz07aadb12006-07-30 06:55:48 +00001178- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1179 This provides the proper warning for struct.pack().
1180 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1181
Neal Norwitz0d62a062006-07-30 06:53:31 +00001182- Patch #1531113: Fix augmented assignment with yield expressions.
1183 Also fix a SystemError when trying to assign to yield expressions.
1184
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001185- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1186 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1187 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1188 excessive filesystem operations during imports.
1189
Tim Petersbc24eee2006-07-27 01:14:53 +00001190- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1191 operations on signed longs that are formally undefined by C.
1192 Unfortunately, at least one compiler now cares about that, so complicated
1193 the code to make that compiler happy again.
1194
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001195- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1196
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001197- Patch #1232023: Stop including current directory in search
1198 path on Windows.
1199
Neal Norwitze1fdb322006-07-21 05:32:28 +00001200- Fix some potential crashes found with failmalloc.
1201
Neal Norwitze7563102006-07-17 01:00:16 +00001202- Fix warnings reported by Klocwork's static analysis tool.
1203
Neal Norwitz84be93b2006-07-16 01:50:38 +00001204- Bug #1512814, Fix incorrect lineno's when code within a function
1205 had more than 255 blank lines.
1206
Georg Brandl9dceedb2006-07-12 15:31:17 +00001207- Patch #1521179: Python now accepts the standard options ``--help`` and
1208 ``--version`` as well as ``/?`` on Windows.
1209
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001210- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001211 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001212 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001213
Tim Peters112aad32006-07-19 00:03:19 +00001214- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001215 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001216 new ``sys._current_frames()`` returns a dictionary with one entry,
1217 mapping the faux "thread id" 0 to the current frame.
1218
Ronald Oussoren3075e162006-07-25 20:28:55 +00001219- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001220

1223-------
1224
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001225- Correction of patch #1455898: In the mbcs decoder, set final=False
1226 for stream decoder, but final=True for the decode function.
1227
Georg Brandl07fec3a2006-08-01 18:49:24 +00001228- os.urandom no longer masks unrelated exceptions like SystemExit or
1229 KeyboardInterrupt.
1230
Tim Peters4643c2f2006-08-10 22:45:34 +00001231- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001232 shutil.copytree on Windows
1233
Georg Brandle34ac7c2006-07-30 11:07:23 +00001234- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1235 refers to file descriptors, not file objects.
1236
Tim Petersc10c9d02006-09-05 02:18:09 +00001237- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001238 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001239 #1513611, and probably others.
1240
Georg Brandledd9b0d2006-07-29 09:33:26 +00001241- Bug #1441397: The compiler module now recognizes module and function
1242 docstrings correctly as it did in Python 2.4.
1243
Tim Peters6f681472006-07-27 23:44:37 +00001244- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1245 lost that tests are sorted by name before being run. This rarely
1246 matters for well-written tests, but can create baffling symptoms if
1247 side effects from one test to the next affect outcomes. ``DocTestFinder``
1248 has been changed to sort the list of tests it returns.
1249
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001250- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001251 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001252
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001253- Bug #978833: Really close underlying socket in _socketobject.close.
1254
Georg Brandl8c036cc2006-08-20 13:15:39 +00001255- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1256 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001257
Georg Brandlcf0c1722006-07-26 07:23:32 +00001258- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1259 to recursive calls and call it with the failing package name.
1260
Martin v. Löwis0b483032006-07-25 09:53:12 +00001261- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1262
Georg Brandlc13c34c2006-07-24 14:09:56 +00001263- Patch #1515343: Fix printing of deprecated string exceptions with a
1264 value in the traceback module.
1265
Greg Ward48fae7a2006-07-23 16:05:51 +00001266- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1267
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001268- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1269
Brett Cannoncaebe222006-07-18 04:41:36 +00001270- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1271 argument tuple. For arguments where zero is illegal, the value is forced to
1272 the minimum value that is correct. This is to support an undocumented but
1273 common way people used to fill in inconsequential information in the time
1274 tuple pre-2.4.
1275
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001276- Patch #1220874: Update the binhex module for Mach-O.
1277
Barry Warsawb110bad2006-07-21 14:51:07 +00001278- The email package has improved RFC 2231 support, specifically for
1279 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1280 (name*0=<blah>) parameter continuations. This may change the types of
1281 values returned from email.message.Message.get_param() and friends.
1282 Specifically in some cases where non-encoded continuations were used,
1283 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1284 will just return the string (since non-encoded continuations don't have
1285 charset and language parts).
1286
1287 Also, whereas % values were decoded in all parameter continuations, they are
1288 now only decoded in encoded parameter parts.
1289
Ronald Oussoren3075e162006-07-25 20:28:55 +00001290- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1291
1292- Bug #1517996: IDLE now longer shows the default Tk menu when a
1293 path browser, class browser or debugger is the frontmost window on MacOS X
1294
Barry Warsaw00decd72006-07-27 23:43:15 +00001295- Patch #1520294: Support for getset and member descriptors in types.py,
1296 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1297 of an object against these built-in types and more importantly, for getting
1298 their docstrings printed in the interactive interpreter's help() function.

1302-----------------
1303
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001304- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1305 a socket operation on a socket with a timeout, the exception will be
1306 caught correctly. Previously, the exception was not caught.
1307
Thomas Heller1393d6a2006-07-28 21:43:20 +00001308- Patch #1529514: The _ctypes extension is now compiled on more
1309 openbsd target platforms.
1310
Tim Peters9cab5932006-07-28 00:30:00 +00001311- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1312 a memory leak, affecting pickles and deep copies.
1313
Tim Petersbc24eee2006-07-27 01:14:53 +00001314- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001315 Paul Eggert.
1316
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001317- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1318
Thomas Hellerce049a02006-07-14 17:51:14 +00001319- Patch #1521817: Index range checking on ctypes arrays containing
1320 exactly one element enabled again. This allows iterating over these
1321 arrays, without the need to check the array size before.
1322
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001323- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001324 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001325 /dev/null in certain cases; this is now fixed.
1326
Thomas Heller47d7a062006-07-12 08:43:47 +00001327- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1328 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001329
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001330- Because of a misspelled preprocessor symbol, ctypes was always
1331 compiled without thread support; this is now fixed.
1332
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001333- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1334 methods now allow their database parameter to be None as the
1335 sleepycat API allows.
1336
Matt Flemingec926502006-07-28 11:27:27 +00001337- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1338 bluetooth API compared with Linux and FreeBSD.
1339
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001340Tests
1341-----
1342
1343- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1344 how long the test file should take to play. Now accepts taking 2.93 secs
1345 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1346
Georg Brandl4793aa32006-07-28 18:31:39 +00001347- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1348 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1349 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001356Mac
1357---
1358
1359- PythonLauncher now works correctly when the path to the script contains
1360 characters that are treated specially by the shell (such as quotes).
1361
1362- Bug #1527397: PythonLauncher now launches scripts with the working directory
1363 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001364 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001365 expect.

1374-----------------
1375
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001376- Bug #1441486: The literal representation of -(sys.maxint - 1)
1377 again evaluates to a int object, not a long.
1378
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001379- Bug #1501934: The scope of global variables that are locally assigned
1380 using augmented assignment is now correctly determined.
1381
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001382- Bug #927248: Recursive method-wrapper objects can now safely
1383 be released.
1384
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001385- Bug #1417699: Reject locale-specific decimal point in float()
1386 and atof().
1387
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001388- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1389 omit a default "error" argument for NULL pointer. This allows
1390 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001391
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001392- Bug #1519018: 'as' is now validated properly in import statements.
1393
Neal Norwitz28746ab2006-07-09 22:14:42 +00001394- On 64 bit systems, int literals that use less than 64 bits are
1395 now ints rather than longs.
1396
Neal Norwitzed657552006-07-10 00:04:44 +00001397- Bug #1512814, Fix incorrect lineno's when code at module scope
1398 started after line 256.
1399
Tim Peters32a83612006-07-10 21:08:24 +00001400- New function ``sys._current_frames()`` returns a dict mapping thread
1401 id to topmost thread stack frame. This is for expert use, and is
1402 especially useful for debugging application deadlocks. The functionality
1403 was previously available in Fazal Majid's ``threadframe`` extension
1404 module, but it wasn't possible to do this in a wholly threadsafe way from
1405 an extension.

Martin v. Löwis77621582006-07-30 13:27:31 +00001410- Bug #1257728: Mention Cygwin in distutils error message about a missing
1411 VS 2003.
1412
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001413- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1414
Tim Peters32a83612006-07-10 21:08:24 +00001415- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001416 environment variable to be set in order to the SDK environment
1417 for finding the compiler, include files, etc.

1422
Thomas Woutersadd19112006-07-05 11:03:49 +00001423- string.Template() now correctly handles tuple-values. Previously,
1424 multi-value tuples would raise an exception and single-value tuples would
1425 be treated as the value they contain, instead.
1426
Martin v. Löwisede77f52006-07-03 13:01:35 +00001427- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1428 even if some data are received.
1429
Martin v. Löwis45482392006-07-03 12:28:58 +00001430- Bug #1267547: Put proper recursive setup.py call into the
1431 spec file generated by bdist_rpm.
1432
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001433- Bug #1514693: Update turtle's heading when switching between
1434 degrees and radians.
1435
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001436- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001437 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001438
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001439- Bug #1514703: Only setup canvas window in turtle when the canvas
1440 is created.
1441
Martin v. Löwis7596e832006-07-01 15:33:37 +00001442- Bug #1513223: .close() of a _socketobj now releases the underlying
1443 socket again, which then gets closed as it becomes unreferenced.
1444
Fred Drake10497c82006-06-29 02:57:48 +00001445- Bug #1504333: Make sgmllib support angle brackets in quoted
1446 attribute values.
1447
1448- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1449 sgmllib ('[' and ']' were not accepted).
1450
Georg Brandl1be63af2006-06-28 20:23:25 +00001451- Fix a bug in the turtle module's end_fill function.
1452
Brett Cannon53ab5b72006-06-22 16:49:14 +00001453- Bug #1510580: The 'warnings' module improperly required that a Warning
1454 category be either a types.ClassType and a subclass of Warning. The proper
1455 check is just that it is a subclass with Warning as the documentation states.
1456
Georg Brandlad29e632006-06-21 17:45:17 +00001457- The compiler module now correctly compiles the new try-except-finally
1458 statement (bug #1509132).
1459
Neal Norwitz60373cd2006-06-22 06:30:50 +00001460- The wsgiref package is now installed properly on Unix.
1461
Vinay Sajip28e57612006-07-01 10:45:20 +00001462- A bug was fixed in logging.config.fileConfig() which caused a crash on
1463 shutdown when fileConfig() was called multiple times.
1464
Gerhard Häring762fbd32006-07-02 17:48:30 +00001465- The sqlite3 module did cut off data from the SQLite database at the first
1466 null character before sending it to a custom converter. This has been fixed
1467 now.
1468

1470-----------------
1471
Tim Peters112aad32006-07-19 00:03:19 +00001472- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1473 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1474 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001475
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001476- Assigning None to pointer type fields in ctypes structures possible
1477 overwrote the wrong fields, this is fixed now.
1478
1479- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1480 on non-Windows platforms.
1481
1482- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1483 integer or long, without range checking.
1484
1485- Patch #1517790: It is now possible to use custom objects in the ctypes
1486 foreign function argtypes sequence as long as they provide a from_param
1487 method, no longer is it required that the object is a ctypes type.
1488
1489- The '_ctypes' extension module now works when Python is configured
1490 with the --without-threads option.
1491
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001492- Bug #1513646: os.access on Windows now correctly determines write
1493 access, again.
1494
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001495- Bug #1512695: cPickle.loads could crash if it was interrupted with
1496 a KeyboardInterrupt.
1497
Neal Norwitza12aa882006-07-06 06:45:08 +00001498- Bug #1296433: parsing XML with a non-default encoding and
1499 a CharacterDataHandler could crash the interpreter in pyexpat.
1500
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001501- Patch #1516912: improve Modules support for OpenVMS.

1507
Tim Peters32a83612006-07-10 21:08:24 +00001508- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001509 Previously, the slight difference could cause compilation errors of the
1510 'zlib' module on systems with more than one version of zlib.
1511
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001512- The MSI compileall step was fixed to also support a TARGETDIR

1543Core and builtins
1544-----------------
1545
Georg Brandla56b9152006-06-19 06:35:54 +00001546- Patch #1507676: Error messages returned by invalid abstract object operations
1547 (such as iterating over an integer) have been improved and now include the
1548 type of the offending object to help with debugging.
1549
Brett Cannonea3912b2006-06-13 21:46:41 +00001550- Bug #992017: A classic class that defined a __coerce__() method that returned
1551 its arguments swapped would infinitely recurse and segfault the interpreter.
1552
Neal Norwitz909eb122006-06-12 02:13:21 +00001553- Fix the socket tests so they can be run concurrently.
1554
Neal Norwitzb9845e72006-06-12 02:11:18 +00001555- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001556 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001557
Brett Cannon22565aa2006-06-09 22:31:23 +00001558- Bug #532646: object.__call__() will continue looking for the __call__
1559 attribute on objects until one without one is found. This leads to recursion
1560 when you take a class and set its __call__ attribute to an instance of the
1561 class. Originally fixed for classic classes, but this fix is for new-style.
1562 Removes the infinite_rec_3 crasher.
1563
Georg Brandl24250812006-06-09 18:45:48 +00001564- The string and unicode methods startswith() and endswith() now accept
1565 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1566
Brett Cannonde3b0522006-06-08 17:00:45 +00001567- Buffer objects, at the C level, never used the char buffer
1568 implementation even when the char buffer for the wrapped object was
1569 explicitly requested (originally returned the read or write buffer).
1570 Now a TypeError is raised if the char buffer is not present but is
1571 requested.
1572
Georg Brandlddbaa662006-06-04 21:56:52 +00001573- Patch #1346214: Statements like "if 0: suite" are now again optimized
1574 away like they were in Python 2.4.
1575
Georg Brandlb7c8f542006-05-27 12:30:25 +00001576- Builtin exceptions are now full-blown new-style classes instead of
1577 instances pretending to be classes, which speeds up exception handling
1578 by about 80% in comparison to 2.5a2.
1579
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001580- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1581 Unicode 4.1.
1582
Georg Brandlf4ef1162006-05-26 18:03:31 +00001583- Patch #921466: sys.path_importer_cache is now used to cache valid and
1584 invalid file paths for the built-in import machinery which leads to
1585 fewer open calls on startup.
1586
Tim Peters696cf432006-05-24 21:10:40 +00001587- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1588 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1589 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1590 the number of input digits (it was and remains linear-time for bases
1591 2, 4, 8, 16 and 32).
1592
Tim Petersb713ec22006-05-23 18:45:30 +00001593- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1594 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1595 an integer close to ``sys.maxint``. This was repaired by patch
1596 #1335972, which also gives a nice speedup.
1597
Richard Jonescebbefc2006-05-23 18:28:17 +00001598- Patch #1337051: reduced size of frame objects.
1599
1600- PyErr_NewException now accepts a tuple of base classes as its
1601 "base" parameter.
1602
Richard Jones7c88dcc2006-05-23 10:37:38 +00001603- Patch #876206: function call speedup by retaining allocated frame
1604 objects.
1605
Georg Brandl7b90e162006-05-18 07:01:27 +00001606- Bug #1462152: file() now checks more thoroughly for invalid mode
1607 strings and removes a possible "U" before passing the mode to the
1608 C library function.
1609
Neal Norwitz1004a532006-05-15 07:17:23 +00001610- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1611
Neal Norwitz373f0a72006-05-15 07:04:36 +00001612- Bug #1487966: Fix SystemError with conditional expression in assignment
1613
Martin v. Löwis879768d2006-05-11 13:28:43 +00001614- WindowsError now has two error code attributes: errno, which carries
1615 the error values from errno.h, and winerror, which carries the error
1616 values from winerror.h. Previous versions put the winerror.h values
1617 (from GetLastError()) into the errno attribute.
1618
Martin v. Löwis77736712006-05-04 05:51:03 +00001619- Patch #1475845: Raise IndentationError for unexpected indent.
1620
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001621- Patch #1479181: split open() and file() from being aliases for each other.
1622
Tim Peters44bd9862006-06-01 13:49:23 +00001623- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1624 methods were always silently ignored by dictionaries when comparing keys.
1625 They are now passed through (except when using the C API function
1626 ``PyDict_GetItem()``, whose semantics did not change).
1627
1628- Bug #1456209: In some obscure cases it was possible for a class with a
1629 custom ``__eq__()`` method to confuse dict internals when class instances
1630 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1631 No, you don't have any code that did this ;-)

1639
Brett Cannon6ee7d012006-06-08 16:23:04 +00001640- Change binascii.hexlify to accept a read-only buffer instead of only a char
1641 buffer and actually follow its documentation.
1642
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001643- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1644
Nick Coghlanc649ec52006-05-29 12:43:05 +00001645- Patch #1478788 (modified version): The functional extension module has
1646 been renamed to _functools and a functools Python wrapper module added.
1647 This provides a home for additional function related utilities that are
1648 not specifically about functional programming. See PEP 309.
1649
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001650- Patch #1493701: performance enhancements for struct module.

Georg Brandl8d3342b2006-05-16 07:38:27 +00001654- Patch #1435422: zlib's compress and decompress objects now have a
1655 copy() method.
1656
Andrew MacIntyre92913322006-06-13 15:04:24 +00001657- Patch #1454481: thread stack size is now tunable at runtime for thread
1658 enabled builds on Windows and systems with Posix threads support.
1659
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001660- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1661 (up to the system limit of 32K characters).
1662
1663- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1664 As a result, these functions now raise WindowsError instead of OSError.
1665
Tim Peters7a822da2006-05-25 21:50:17 +00001666- ``time.clock()`` on Win64 should use the high-performance Windows
1667 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1668 Windows platforms).
1669
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001670- Calling Tk_Init twice is refused if the first call failed as that
1671 may deadlock.
1672
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001673- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1674 accept it without potentially using an uninitialized pointer.
1675
1676- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1677 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

1684 parameter is supplied. [SF pybsddb bug #1477863]
1685
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001686- bsddb: the __len__ method of a DB object has been fixed to return correct
1687 results. It could previously incorrectly return 0 in some cases.
1688 Fixes SF bug 1493322 (pybsddb bug 1184012).
1689
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001690- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1691 aborts the db transaction safely when a modifier callback fails.
1692 Fixes SF python patch/bug #1408584.
1693
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001694- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001695 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001696 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1697 database calls that would previously deadlock. [SF python bug #775414]

1727 double-byte encodings.
1728
Tim Peters43898b42006-06-14 04:09:25 +00001729- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1730 guarantee that adjacent triples in the return list always describe
1731 non-adjacent blocks. Previously, a pair of matching blocks could end
1732 up being described by multiple adjacent triples that formed a partition
1733 of the matching pair.
1734
Greg Ward0e0c9f42006-06-11 16:24:11 +00001735- Bug #1498146: fix optparse to handle Unicode strings in option help,

Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001743- The wsgiref package has been added to the standard library.
1744
Nick Coghlan676725d2006-06-08 13:54:49 +00001745- The functions update_wrapper() and wraps() have been added to the functools
1746 module. These make it easier to copy relevant metadata from the original
1747 function when writing wrapper functions.
1748
Tim Petersd6a9eef2006-06-05 01:48:21 +00001749- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1750 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001751
Martin v. Löwis3f767792006-06-04 19:36:28 +00001752- Patch #1359618: Speed up charmap encoder by using a trie structure
1753 for lookup.
1754
Tim Petersd609b1a2006-06-02 23:22:51 +00001755- The functions in the ``pprint`` module now sort dictionaries by key
1756 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1757 if and only if its display required more than one line, although that
1758 wasn't documented. The new behavior increases predictability; e.g.,
1759 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1760
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001761- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1762 (thanks for J. J. Lee).
1763
Georg Brandl2b330372006-05-28 20:23:12 +00001764- Patch #1496206: improve urllib2 handling of passwords with respect to
1765 default HTTP and HTTPS ports.
1766
George Yoshidaf3c65de2006-05-28 16:39:09 +00001767- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1768
Bob Ippolito7298f272006-05-23 18:43:47 +00001769- Patch #1281707: speed up gzip.readline.
1770
Georg Brandlb89316f2006-05-17 15:51:16 +00001771- Patch #1180296: Two new functions were added to the locale module:
1772 format_string() to get the effect of "format % items" but locale-aware,
1773 and currency() to format a monetary number with currency sign.
1774
Georg Brandle3a25832006-05-17 14:56:04 +00001775- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1776 and several features added, such as speed and geometry control.
1777
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001778- Patch #1488881: add support for external file objects in bz2 compressed
1779 tarfiles.
1780
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001781- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1782 stdout arguments, making it possible to redirect input and output
1783 for remote debugging.
1784
1785- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1786 a couple of issues, notably handling of long file names using the
1787 GNU LONGNAME extension.
1788
1789- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1790 new flag when ``name`` is already the name of an option flag.
1791
1792- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1793 package.
1794
1795- Patch #1472854: make the rlcompleter.Completer class usable on non-
1796 UNIX platforms.
1797
1798- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1799
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001800- Bug #1472827: correctly escape newlines and tabs in attribute values in
1801 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001831What's New in Python 2.5 alpha 2?
1832=================================
1833
1834*Release date: 27-APR-2006*
1835
1836Core and builtins
1837-----------------
1838
Thomas Heller1b046642006-04-18 18:51:06 +00001839- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1840 by converting these apis from macros into exported functions again:
1841
1842 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1843 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1844 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1845 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1846 PyRun_String Py_CompileString
1847
Martin v. Löwis45294a92006-04-18 06:24:08 +00001848- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1849
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001850- All uses of PyStructSequence_InitType have been changed to initialize
1851 the type objects only once, even if the interpreter is initialized
1852 multiple times.
1853
Neal Norwitz61546162006-04-14 05:20:28 +00001854- Bug #1454485, array.array('u') could crash the interpreter. This was
1855 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1856 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1857
1858- Py_UNICODE is unsigned. It was always documented as unsigned, but
1859 due to a bug had a signed value in previous versions.
1860
Tim Peters3a5e8b12006-04-11 01:44:07 +00001861- Patch #837242: ``id()`` of any Python object always gives a positive
1862 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1863 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001864 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001865 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001866
Tim Peters3a5e8b12006-04-11 01:44:07 +00001867 def __hash__(self):
1868 return id(self) # WRONG
1869
1870 because a hash result must be a (short) Python int but it was always
1871 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001872 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001873 was always usable as a hash value before this patch. That's no longer
1874 necessarily so.
1875
1876- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001877 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001878 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001879 #1454844)
1880
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001881- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1882 involving generators that have paused outside of any ``try`` or ``with``
1883 blocks. (In 2.5a1, a paused generator that was part of a reference
1884 cycle could not be garbage collected, regardless of whether it was
1885 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001886
Anthony Baxter51bcb682006-04-05 14:51:42 +00001887Extension Modules

Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001890- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1891 is a macro.
1892
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001893- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1894 fails with an error condition.
1895
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001896- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1897
1898- Bug #1117761: bsddb.*open() no longer raises an exception when using
1899 the cachesize parameter.
1900
1901- Bug #1149413: bsddb.*open() no longer raises an exception when using
1902 a temporary db (file=None) with the 'n' flag to truncate on open.
1903
1904- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1905 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001906
Armin Rigoa9017c32006-04-19 11:50:27 +00001907- Patch #1062014: AF_UNIX sockets under Linux have a special
1908 abstract namespace that is now fully supported.

1911-------
1912
Peter Astrand7d1d4362006-07-14 14:04:45 +00001913- Bug #1223937: subprocess.CalledProcessError reports the exit status
1914 of the process using the returncode attribute, instead of
1915 abusing errno.
1916
Tim Peters711bf302006-04-25 03:31:36 +00001917- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1918 a doctest to be skipped (the code is not run, and the expected output
1919 or exception is ignored).
1920
Nick Coghlanda2268f2006-04-24 04:37:15 +00001921- Fixed contextlib.nested to cope with exceptions being raised and
1922 caught inside exit handlers.
1923
Greg Wardab05edc2006-04-23 03:47:58 +00001924- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1925 hex, octal, or binary; add ``append_const`` action; keep going if
1926 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1927 added ``epilog`` for better help generation).
1928
Tim Peters21fbd572006-04-21 21:18:10 +00001929- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1930 called from a thread spawned as a side effect of importing a module.
1931
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001932- The pydoc module now supports documenting packages contained in
1933 .zip or .egg files.
1934
1935- The pkgutil module now has several new utility functions, such
1936 as ``walk_packages()`` to support working with packages that are either
1937 in the filesystem or zip files.
1938
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001939- The mailbox module can now modify and delete messages from
1940 mailboxes, in addition to simply reading them. Thanks to Gregory
1941 K. Johnson for writing the code, and to the 2005 Google Summer of
1942 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001943
Tim Petersc7605f22006-04-17 21:12:33 +00001944- The ``__del__`` method of class ``local`` in module ``_threading_local``
1945 returned before accomplishing any of its intended cleanup.
1946
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001947- Patch #790710: Add breakpoint command lists in pdb.
1948

1952
Anthony Baxtere29002c2006-04-12 12:07:31 +00001953- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1954 Windows. Bug #1469163.
1955
Phillip J. Eby47032112006-04-11 01:07:43 +00001956- The warnings, linecache, inspect, traceback, site, and doctest modules
1957 were updated to work correctly with modules imported from zipfiles or
1958 via other PEP 302 __loader__ objects.
1959
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001960- Patch #1467770: Reduce usage of subprocess._active to processes which
1961 the application hasn't waited on.

1971-----
1972
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001973- The Makefile now has a reindent target, which runs reindent.py on
1974 the library.
1975
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001976- Patch #1470875: Building Python with MS Free Compiler

1981 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001982 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001983 CXX from --with-cxx-main, see description in README.
1984
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001985- Patch #1429775: Link extension modules with the shared libpython.

Hye-Shik Changf4795c82006-04-26 19:20:26 +00001987- Fixed a libffi build problem on MIPS systems.
1988
Tim Peters8931ff12006-05-13 23:28:20 +00001989- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1990 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1991 and "%zu" for unsigned integers of type ``size_t``.
1992
Anthony Baxter51bcb682006-04-05 14:51:42 +00001993Tests
1994-----
1995
Nick Coghlanda2268f2006-04-24 04:37:15 +00001996- test_contextlib now checks contextlib.nested can cope with exceptions
1997 being raised and caught inside exit handlers.
1998
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001999- test_cmd_line now checks operation of the -m and -c command switches
2000
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002001- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2002 it separately and by hand. It also wasn't cleaning up its changes to
2003 the current Decimal context.
2004
Thomas Woutersabd08882006-04-26 15:53:30 +00002005- regrtest.py now has a -M option to run tests that test the new limits of
2006 containers, on 64-bit architectures. Running these tests is only sensible
2007 on 64-bit machines with more than two gigabytes of memory. The argument
2008 passed is the maximum amount of memory for the tests to use.

2022 and attempted to bring other PEP 343 related documentation into
2023 line with the implementation and/or python-dev discussions.
2024
Tim Peters8dc73d22006-04-24 02:03:16 +00002025- Bug #1337990: clarified that ``doctest`` does not support examples

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002029What's New in Python 2.5 alpha 1?
2030=================================
2031
Anthony Baxterebed3f62006-04-03 15:03:44 +00002032*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002033
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002034Core and builtins
2035-----------------
2036
Nick Coghlan43832302006-04-23 17:04:07 +00002037- PEP 338: -m command line switch now delegates to runpy.run_module

2039
Martin v. Löwisc661b882006-04-20 04:54:23 +00002040- On Windows, .DLL is not an accepted file name extension for
2041 extension modules anymore; extensions are only found if they
2042 end in .PYD.
2043
Martin v. Löwisea62d252006-04-03 10:56:49 +00002044- Bug #1421664: sys.stderr.encoding is now set to the same value as
2045 sys.stdout.encoding.
2046

2050
Anthony Baxter262c00a2006-03-30 10:53:17 +00002051- Fixed bug #1459029 - unicode reprs were double-escaped.
2052
Hye-Shik Changd478f342006-03-23 12:32:36 +00002053- Patch #1396919: The system scope threads are reenabled on FreeBSD
2054 5.4 and later versions.
2055
Neal Norwitze98ccf62006-03-23 05:39:47 +00002056- Bug #1115379: Compiling a Unicode string with an encoding declaration
2057 now gives a SyntaxError.
2058
Georg Brandlabd1ff82006-03-18 07:59:59 +00002059- Previously, Python code had no easy way to access the contents of a
2060 cell object. Now, a ``cell_contents`` attribute has been added
2061 (closes patch #1170323).
2062
Tim Peterscf79aac2006-03-16 01:14:46 +00002063- Patch #1123430: Python's small-object allocator now returns an arena to
2064 the system ``free()`` when all memory within an arena becomes unused
2065 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2066 freed. Some applications will see a drop in virtual memory size now,
2067 especially long-running applications that, from time to time, temporarily
2068 use a large number of small objects. Note that when Python returns an
2069 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002070 platform C library will in turn return that memory to the operating system.
2071 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002072 appears to be effective at least on Microsoft C and gcc-based systems.
2073 Thanks to Evan Jones for hard work and patience.
2074
Georg Brandl533ff6f2006-03-08 18:09:27 +00002075- Patch #1434038: property() now uses the getter's docstring if there is
2076 no "doc" argument given. This makes it possible to legitimately use
2077 property() as a decorator to produce a read-only property.
2078
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002079- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2080 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2081 of requiring an int or long in slicing and a few other contexts, enabling
2082 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2083
Neal Norwitz995acdf2006-03-07 05:01:00 +00002084- Fixed various bugs reported by Coverity's Prevent tool.
2085
Brett Cannonbf364092006-03-01 04:25:17 +00002086- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2087 new exception base class, BaseException, which has a new message attribute.
2088 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2089 Raising a string exception now raises a DeprecationWarning.
2090
Thomas Woutersfb609f42006-02-28 16:37:25 +00002091- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2092 explicitly relative, using 'from .module import name' to mean 'from the same
2093 package as this module is in. Imports without dots still default to the
2094 old relative-then-absolute, unless 'from __future__ import
2095 absolute_import' is used.
2096
Brett Cannona7446e32006-02-27 23:39:10 +00002097- Properly check if 'warnings' raises an exception (usually when a filter set
2098 to "error" is triggered) when raising a warning for raising string
2099 exceptions.
2100
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002101- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002102 The name was removed from Include/code.h.
2103
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002104- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002105
Guido van Rossum1968ad32006-02-25 22:38:04 +00002106- Patch 1433928:
2107 - The copy module now "copies" function objects (as atomic objects).
2108 - dict.__getitem__ now looks for a __missing__ hook before raising
2109 KeyError.
2110
Tim Peters84ef21c2006-02-28 20:39:06 +00002111- PEP 343: with statement implemented. Needs ``from __future__ import
2112 with_statement``. Use of 'with' as a variable will generate a warning.
2113 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002114 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002115 The following objects have __context__ methods:
2116 - The built-in file type.
2117 - The thread.LockType type.
2118 - The following types defined by the threading module:
2119 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2120 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002121
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002122- Fix the encodings package codec search function to only search
2123 inside its own package. Fixes problem reported in patch #1433198.
2124
2125 Note: Codec packages should implement and register their own
2126 codec search function. PEP 100 has the details.
2127
Tim Peters9ea89d22006-06-04 03:26:02 +00002128- PEP 353: Using ``Py_ssize_t`` as the index type.
2129
2130- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2131 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2132 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2133 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2134 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002135
Neal Norwitzfc76d632006-01-10 06:03:13 +00002136- Patch #1400181, fix unicode string formatting to not use the locale.
2137 This is how string objects work. u'%f' could use , instead of .
2138 for the decimal point. Now both strings and unicode always use periods.
2139
Neal Norwitz671b9e32006-01-09 07:07:12 +00002140- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2141 configure would break checking curses.h.
2142
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002143- Bug #959576: The pwd module is now builtin. This allows Python to be
2144 built on UNIX platforms without $HOME set.
2145
Neal Norwitzc10978f2005-12-19 06:07:16 +00002146- Bug #1072182, fix some potential problems if characters are signed.
2147
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002148- Bug #889500, fix line number on SyntaxWarning for global declarations.
2149
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002150- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2151
Neal Norwitze7214a12005-12-18 05:03:17 +00002152- Support for converting hex strings to floats no longer works.
2153 This was not portable. float('0x3') now raises a ValueError.
2154
Barry Warsaw2a38a862005-12-18 01:27:35 +00002155- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002156 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002157 is now displayed in interactive prompt banner.
2158
Georg Brandlfa166682005-12-17 21:45:17 +00002159- Implementation of PEP 341 - Unification of try/except and try/finally.
2160 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002161 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002162
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002163- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2164 now encodes backslash correctly.
2165
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002166- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2167
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002168- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002169 and long longs.
2170
Neal Norwitz67715f02005-11-09 06:59:35 +00002171- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002172 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002173 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002174
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002175- Replaced most Unicode charmap codecs with new ones using the
2176 new Unicode translate string feature in the builtin charmap
2177 codec; the codecs were created from the mapping tables available
2178 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2179 encodings now include a mapping for the Apple logo)
2180
Tim Peterse3547fd2005-12-16 23:13:57 +00002181- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002182
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002183- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002184
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002185- A new AST parser implementation was completed. The abstract
2186 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002187 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002188
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002189- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002190 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2191
Neal Norwitz708e51a2005-10-03 04:48:15 +00002192- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2193
Neal Norwitz11bd1192005-10-03 00:54:56 +00002194- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2195 Provide a warning when a directory is passed on the command line.
2196
Neal Norwitz40d37812005-10-02 01:48:49 +00002197- Fix segfault with invalid coding.
2198
2199- SF bug #772896: unknown encoding results in MemoryError.
2200
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002201- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002202 supported a __len__() method which evaluated to False when the iterator
2203 was empty.
2204
Guido van Rossum630db602005-09-20 18:49:54 +00002205- On 64-bit platforms, when __len__() returns a value that cannot be
2206 represented as a C int, raise OverflowError.
2207
Skip Montanarof8948ca2005-09-19 03:54:46 +00002208- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002209 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002210
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002211- SF bug #893549: parsing keyword arguments was broken with a few format
2212 codes.
2213
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002214- Changes donated by Elemental Security to make it work on AIX 5.3
2215 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2216 bug #105470: test_pwd fails on 64bit system (Opteron).
2217
Guido van Rossum539c6622005-09-14 17:49:54 +00002218- Changes donated by Elemental Security to make it work on HP-UX 11 on
2219 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2220
Georg Brandl4550b8d2005-08-26 06:43:52 +00002221- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002222 (fixes bug #1119418).
2223
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002224- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2225
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002226- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2227 exceptions that cause a function to exit.
2228
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002229- The implementation of set() and frozenset() was revised to use its
2230 own internal data structure. Memory consumption is reduced by 1/3
2231 and there are modest speed-ups as well. The API is unchanged.
2232
Tim Petersde7990b2005-07-17 23:45:23 +00002233- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2234
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002235- SF bug #1229429: PyObject_CallMethod failed to decrement some
2236 reference counts in some error exit cases.
2237
Tim Petersecc6e6a2005-07-10 22:30:55 +00002238- SF bug #1185883: Python's small-object memory allocator took over
2239 a block managed by the platform C library whenever a realloc specified
2240 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002241 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002242 portable way to copy data from the C-managed block into Python's
2243 small-object space without risking a memory fault. Python's small-object
2244 realloc now leaves such blocks under the control of the platform C
2245 realloc.
2246
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002247- SF bug #1232517: An overflow error was not detected properly when
2248 attempting to convert a large float to an int in os.utime().
2249
Raymond Hettinger3296e692005-06-29 23:29:56 +00002250- SF bug #1224347: hex longs now print with lowercase letters just
2251 like their int counterparts.
2252
Michael W. Hudson188d4362005-06-20 16:52:57 +00002253- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2254 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2255 interpreter states; back out that fix and do a better job (see
2256 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2257 for a longer write-up of the problem).
2258
Michael W. Hudsondf888462005-06-03 14:41:55 +00002259- SF patch #1180995: marshal now uses a binary format by default when
2260 serializing floats.
2261
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002262- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2263 the routines that promise to produce IEEE 754 binary representations
2264 of floats now simply copy bytes around.
2265
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002266- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2267 278.
2268
Brett Cannonc3647ac2005-04-26 03:45:26 +00002269- patch #1109424: int, long, float, complex, and unicode now check for the
2270 proper magic slot for type conversions when subclassed. Previously the
2271 magic slot was ignored during conversion. Semantics now match the way
2272 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002273 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002274 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002275 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002276
Barry Warsawc8d907c2005-04-19 23:43:40 +00002277- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2278 NULL, now raise an AttributeError when attempting to set or delete the
2279 attribute. Previously a TypeError was raised, but this was inconsistent
2280 with the equivalent pure-Python implementation.
2281
Michael W. Hudson774479c2005-04-18 08:46:17 +00002282- It is now safe to call PyGILState_Release() before
2283 PyEval_InitThreads() (note that if there is reason to believe there
2284 are multiple threads around you still must call PyEval_InitThreads()
2285 before using the Python API; this fix is for extension modules that
2286 have no way of knowing if Python is multi-threaded yet).
2287
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002288- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2289 disabled caused a crash.
2290
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002291- Bug #1165306: instancemethod_new allowed the creation of a method
2292 with im_class == im_self == NULL, which caused a crash when called.
2293
Tim Petersecc6e6a2005-07-10 22:30:55 +00002294- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002295 fixes the crash seen in bug #1165761
2296
Raymond Hettinger96229b12005-03-11 06:49:40 +00002297- Added two new builtins, any() and all().
2298
Brett Cannon409d8f22005-03-05 06:47:57 +00002299- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002300 (e.g., ``class C(): pass`` is no longer a syntax error).
2301 Patch #1176012 added support to the 'parser' module and 'compiler' package
2302 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002303
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002304- Patch #1115086: Support PY_LONGLONG in structmember.
2305
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002306- Bug #1155938: new style classes did not check that __init__() was
2307 returning None.
2308
Tim Petersecc6e6a2005-07-10 22:30:55 +00002309- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002310 ('\') with a specific error message.
2311
Martin v. Löwisff232d72005-03-03 09:24:38 +00002312- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2313
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002314- Bug #1124295: the __name__ attribute of file objects was
2315 inadvertently made inaccessible in restricted mode.

2336 unicode instance if the argument is not an instance of basestring and
2337 calling __str__ on the argument returns a unicode instance.
2338
Tim Petersf4e69282006-02-27 17:15:31 +00002339- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2340 current thread state when the auto-GIL-state machinery knows about
2341 it (since the thread state is being deleted, continuing to remember it
2342 can't help, but can hurt if another thread happens to get created with
2343 the same thread id).

Nick Coghlan43832302006-04-23 17:04:07 +00002539- PEP 338: new module runpy defines a run_module function to support
2540 executing modules which provide access to source code or a code object
2541 via the PEP 302 import mechanisms.

2551 in attribute values.
2552
Anthony Baxterc51ee692006-04-01 00:57:31 +00002553- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002554 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002555 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002556 module will not be built.

Tim Petersc17976e2006-04-01 00:26:53 +00002558- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2559 aren't officially supported here, and trying to use them will probably

Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002582- email 4.0 package now integrated. This is largely the same as the email 3.0
2583 package that was included in Python 2.3, except that PEP 8 module names are
2584 now used (e.g. mail.message instead of email.Message). The MIME classes
2585 have been moved to a subpackage (e.g. email.mime.text instead of
2586 email.MIMEText). The old names are still supported for now. Several
2587 deprecated Message methods have been removed and lots of bugs have been
2588 fixed. More details can be found in the email package documentation.

Walter Dörwald40108c92006-03-27 08:15:44 +00002590- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2591 (a subclass of tuple) that provides incremental decoders and encoders
2592 (a way to use stateful codecs without the stream API). Python functions
2593 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2594 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2595 have been added.

2598 a ValueError instead of a StopIteration now (like file and cString.String do).
2599 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2600 called before (like file and StringIO.StringIO do).

2676 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2677 Ronald L. Rivest offered this advice for Python:
2678
2679 "The consensus of researchers in this area (at least as
2680 expressed at the NIST Hash Function Workshop 10/31/05),
2681 is that SHA-256 is a good choice for the time being, but
2682 that research should continue, and other alternatives may
2683 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002684

Guido van Rossumd0641422005-02-03 15:01:24 +00002844- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2845 disables recursive traversal through instance attributes, which can
2846 be exploited in various ways.
2847
Tim Peterse3547fd2005-12-16 23:13:57 +00002848- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002849 flags on the HTTP listening socket.
2850
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002851- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2852 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2853
Fred Drakefbdeaad2006-07-29 16:56:15 +00002854- Patches #893642, #1039083: add allow_none, encoding arguments to
2855 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002856
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002857- Bug #1110478: Revert os.environ.update to do putenv again.
2858
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002859- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2860
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002861- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2862
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002863- Enhancements to the csv module:
2864
2865 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002866 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002867 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002868 + Dialect parameter parsing has been re-implemented to improve error
2869 reporting.
2870 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2871 dictates.
2872 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002873 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002874 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002875 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2876 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002877 + reader now allows \r characters to be quoted (previously it only allowed
2878 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002879 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002880 + Dialect classes passed to the module are no longer instantiated by
2881 the module before being parsed (the former validation scheme required
2882 this, but the mechanism was unreliable).
2883 + The dialect registry now contains instances of the internal
2884 C-coded dialect type, rather than references to python objects.
2885 + the internal c-coded dialect type is now immutable.
2886 + register_dialect now accepts the same keyword dialect specifications
2887 as the reader and writer, allowing the user to register dialects
2888 without first creating a dialect class.
2889 + a configurable limit to the size of parsed fields has been added -
2890 previously, an unmatched quote character could result in the entire
2891 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002892 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002893 the parser field size limit (returning the former limit). The initial
2894 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002895 + A line_num attribute has been added to the reader object, which tracks
2896 the number of lines read from the source iterator. This is not
2897 the same as the number of records returned, as records can span
2898 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002899 + reader and writer objects were not being registered with the cyclic-GC.
2900 This has been fixed.
2901
Brett Cannone6539c42005-01-08 02:43:53 +00002902- _DummyThread objects in the threading module now delete self.__block that is
2903 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2904 lock primitives tend to be limited in number and thus should not be wasted on
2905 a _DummyThread object. Fixes bug #1089632.
2906
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002907- The imghdr module now detects Exif files.
2908
Raymond Hettinger6065d322004-12-20 23:51:53 +00002909- StringIO.truncate() now correctly adjusts the size attribute.
2910 (Bug #951915).
2911
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002912- locale.py now uses an updated locale alias table (built using
2913 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2914 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002915 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002916
Raymond Hettinger3557f422004-12-07 12:02:02 +00002917- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2918
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002919- the pickle module no longer accepts the deprecated None option in the
2920 args tuple returned by __reduce__().
2921
Brett Cannon84667c02004-12-07 03:25:18 +00002922- optparse now optionally imports gettext. This allows its use in setup.py.
2923
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002924- the pickle module no longer uses the deprecated bin parameter.
2925
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002926- the shelve module no longer uses the deprecated binary parameter.
2927
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002928- the pstats module no longer uses the deprecated ignore() method.
2929
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002930- the filecmp module no longer uses the deprecated use_statcache argument.
2931
Raymond Hettinger664347b2004-12-04 21:21:53 +00002932- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2933 extended or overridden by subclasses. Formerly, the subclassed method would
2934 be ignored by the rest of the module. (Bug #1078905).
2935
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002936- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002937 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002938
Walter Dörwald36733692004-12-22 12:50:50 +00002939- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2940 once when a size argument is given. This prevents a buffer overflow in the
2941 tokenizer with very long source lines.
2942
Barry Warsaw538561e2006-01-01 21:48:54 +00002943- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2944 immediately after creating the object, without any intervening
2945 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002946
Skip Montanaro05885812005-01-16 20:48:27 +00002947- The reconvert.quote function can now emit triple-quoted strings. The
2948 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002949
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002950- ``UserString.MutableString`` now supports negative indices in
2951 ``__setitem__`` and ``__delitem__``
2952
Greg Ward40407942005-03-05 02:53:17 +00002953- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2954 correctly.
2955
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002956- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2957 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2958 character even if the user has passed a size parameter to get a proper
2959 line ending. Remove the special handling of a "\r\n" that has been split
2960 between two lines.
2961
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002962- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2963 about illegal code points. The codec now supports PEP 293 style error
2964 handlers.
2965
Walter Dörwald78a78b02005-09-01 12:04:29 +00002966- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002967 from the input stream, so that the output is a byte string in the correct
2968 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002969
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002970- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2971 considering it exactly like a '*'.
2972
Walter Dörwald007f8df2005-10-09 19:42:27 +00002973- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2974 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002975
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002976- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2977
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002978- Patch #1413711: Certain patterns of differences were making difflib
2979 touch the recursion limit.
2980
Walter Dörwald58917a62006-03-31 15:26:22 +00002981- Bug #947906: An object oriented interface has been added to the calendar
2982 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002983 called as a script (e.g. via ``python -mcalendar``). Localized month and
2984 weekday names can be ouput (even if an exotic encoding is used) using
2985 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002986
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002987Build
2988-----
2989
Neal Norwitz602d3392006-03-31 08:21:40 +00002990- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2991 by using -mieee gcc option.
2992

2994
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002995- Build support for Win64-AMD64 was added.
2996
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002997- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2998
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002999- Patch #881820: look for openpty and forkpty also in libbsd.
3000
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003001- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3002 The zlib module is now builtin on Windows.
3003
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003004- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3005
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003006- Bug #1189330: configure did not correctly determine the necessary
3007 value of LINKCC if python was built with GCC 4.0.
3008
Trent Mick8321b422005-07-26 02:29:21 +00003009- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3010 vulnerability in zlib 1.2.1 and 1.2.2.
3011
Brett Cannon08cd5982005-04-24 22:26:38 +00003012- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3013 flags that change binary compatibility. Changes were also made to
3014 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003015 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003016
Bob Ippolitoed233462005-03-29 13:47:59 +00003017- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3018 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3019 no longer exists). This configure patch makes things right.
3020
Martin v. Löwise2713be2005-03-08 15:03:08 +00003021- Bug #1158607: Build with --disable-unicode again.
3022
Brett Cannon46d96232005-02-16 00:07:19 +00003023- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3024 defined. Discovered as a result of not being able to build on OS X.
3025
Brett Cannon516592f2004-12-07 00:42:59 +00003026- setup.py now uses the directories specified in LDFLAGS using the -L option
3027 and in CPPFLAGS using the -I option for adding library and include
3028 directories, respectively, for compiling extension modules against. This has
3029 led to the core being compiled using the values in CPPFLAGS. It also removes
3030 the need for the special-casing of both DarwinPorts and Fink for darwin since
3031 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3032 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3033 Fink, ``-I/opt/local/include`` for DarwinPorts).
3034
Brett Cannon43802422005-02-10 20:48:03 +00003035- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3036 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3037 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3038 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003040C API
3041-----
3042
Tim Petersc9d78aa2006-03-26 23:27:58 +00003043- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3044 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3045 is obtained via the ``PyObject_`` family, it must be released via the
3046 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3047 always been officially true, but when Python's small-object allocator was
3048 introduced, an attempt was made to cater to a few extension modules
3049 discovered at the time that obtained memory via ``PyObject_New`` but
3050 released it via ``PyMem_DEL``. It's years later, and if such code still
3051 exists it will fail now (probably with segfaults, but calling wrong
3052 low-level memory management functions can yield many symptoms).
3053
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003054- Added a C API for set and frozenset objects.
3055
Raymond Hettinger66517482004-12-03 11:45:13 +00003056- Removed PyRange_New().
3057
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003058- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3059 mapping argument now. This string is used as a mapping table. Byte values
3060 greater than the length of the string and 0xFFFE are treated as undefined
3061 mappings.
