Georg Brandld9f1da02008-03-29 01:50:46 +000015- Patch #1442: properly report exceptions when the PYTHONSTARTUP file
16 cannot be executed.
17
Amaury Forgeot d'Arc8432d862008-03-28 20:45:42 +000018- The compilation of a class nested in another class used to leak one
19 reference on the outer class name.
20
Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +000021- Issue #1477: With narrow Unicode builds, the unicode escape sequence
22 \Uxxxxxxxx did not accept values outside the Basic Multilingual Plane. This
23 affected raw unicode literals and the 'raw-unicode-escape' codec. Now
24 UTF-16 surrogates are generated in this case, like normal unicode literals
25 and the 'unicode-escape' codec.
26
Neal Norwitzb3635f92008-03-18 04:17:36 +000027- Issue #2321: use pymalloc for unicode object string data to reduce
28 memory usage in some circumstances.

34 parameter but was not verifying that it was greater than zero. Values
35 less than zero will now raise a SystemError and return NULL to indicate a
36 bug in the calling C code.

Amaury Forgeot d'Arc198e3532008-03-27 23:41:59 +000042- Issue #2495: tokenize.untokenize now inserts a space between two consecutive
43 string literals; previously, ["" ""] was rendered as [""""], which is
44 incorrect python code.
45
Mark Dickinsonbfdbfd42008-03-25 18:58:13 +000046- Issue #2482: Make sure that the coefficient of a Decimal is always
47 stored as a str instance, not as a unicode instance. This ensures
48 that str(Decimal) is always an instance of str. This fixes a
49 regression from Python 2.5.1 to Python 2.5.2.
50
Mark Dickinson26c25d92008-03-25 14:35:25 +000051- Issue #2478: fix failure of decimal.Decimal(0).sqrt()

60
Martin v. Löwis0e305552008-03-06 07:14:26 +000061- Bug #1725737: In distutil's sdist, exclude RCS, CVS etc. also in the
62 root directory, and also exclude .hg, .git, .bzr, and _darcs.

126
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000127- Issue #1920: "while 0" statements were completely removed by the compiler,
128 even in the presence of an "else" clause, which is supposed to be run when
129 the condition is false. Now the compiler correctly emits bytecode for the
130 "else" suite.

947
Neal Norwitz0bcafac2006-09-11 08:51:17 +0000948- Make _PyGILState_NoteThreadState() static, it was not used anywhere
949 outside of pystate.c and should not be necessary.
950
Brett Cannon19d76c52006-09-09 07:18:44 +0000951- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
952 allows calling unicode() on exceptions classes directly to succeed.
953
Georg Brandlecab6232006-09-06 06:47:02 +0000954- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
955 Also make sure that every exception class has __module__ set to
956 'exceptions'.
957
Georg Brandl37a9e572006-09-06 06:09:34 +0000958- Bug #1550983: emit better error messages for erroneous relative

Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000969- The return tuple from str.rpartition(sep) is (tail, sep, head) where
970 head is the original string if sep was not found.
971
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000972- Bug #1520864: unpacking singleton tuples in list comprehensions and
973 generator expressions (x for x, in ... ) works again. Fixing this problem
974 required changing the .pyc magic number. This means that .pyc files
975 generated before 2.5c2 will be regenerated.

1089
Neal Norwitz24b6f202006-09-05 04:43:56 +00001090- Fix infinite recursion when subclassing long and overriding __hash__.
1091
1092- Fix concatenation (+=) of long strings.
1093
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001094- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001095 compared equal or unequal to a string and a UnicodeDecodeError
1096 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001097
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001098 Instead, the equal (==) and unequal (!=) comparison operators will
1099 now issue a UnicodeWarning and interpret the two objects as
1100 unequal. The UnicodeWarning can be filtered as desired using
1101 the warning framework, e.g. silenced completely, turned into an
1102 exception, logged, etc.
1103
1104 Note that compare operators other than equal and unequal will still
1105 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001106
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001107- Fix segfault when doing string formatting on subclasses of long.
1108
1109- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1110 with new-style classes.
1111
1112- Fix bug related to __len__ functions returning negative values with
1113 classic classes.
1114
1115- Patch #1538606, Fix __index__() clipping. There were some problems
1116 discovered with the API and how integers that didn't fit into Py_ssize_t
1117 were handled. This patch attempts to provide enough alternatives
1118 to effectively use __index__.
1119
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001120- Bug #1536021: __hash__ may now return long int; the final hash
1121 value is obtained by invoking hash on the long int.
1122
Thomas Hellerab1049c2006-08-08 17:37:00 +00001123- Bug #1536786: buffer comparison could emit a RuntimeWarning.

1126 sys.stdin is closed.
1127
Thomas Heller74d36f02006-08-04 18:17:40 +00001128- On Windows, the PyErr_Warn function is now exported from
1129 the Python dll again.
1130
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001131- Bug #1191458: tracing over for loops now produces a line event
1132 on each iteration. Fixing this problem required changing the .pyc
1133 magic number. This means that .pyc files generated before 2.5c1
1134 will be regenerated.
1135
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001136- Bug #1333982: string/number constants were inappropriately stored
1137 in the byte code and co_consts even if they were not used, ie
1138 immediately popped off the stack.
1139
Georg Brandle9462c72006-08-04 18:03:37 +00001140- Fixed a reference-counting problem in property().

1144-------
1145
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001146- Fix a bug in the ``compiler`` package that caused invalid code to be
1147 generated for generator expressions.
1148
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001149- The distutils version has been changed to 2.5.0. The change to
1150 keep it programmatically in sync with the Python version running
1151 the code (introduced in 2.5b3) has been reverted. It will continue
1152 to be maintained manually as static string literal.
1153
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001154- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001155 and this cannot be converted to the required C type, an exception is
1156 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001157 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001158
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001159- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001160 an exception.
1161
Tim Peterscbdd3502006-09-05 01:47:53 +00001162- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001163 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001164 workarounds for clocks with low resolution, to stop the code yielding
1165 duplicate UUIDs.
1166
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001167- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1168 before raising SystemExit, allowing IDLE to honor quit() and exit().
1169
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001170- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.

Georg Brandl7a1af772006-08-14 21:55:28 +00001172- Patch #1536071: trace.py should now find the full module name of a
1173 file correctly even on Windows.
1174
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001175- logging's atexit hook now runs even if the rest of the module has
1176 already been cleaned up.
1177
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001178- Bug #1112549, fix DoS attack on cgi.FieldStorage.

1181 str(exception) raised an exception.
1182
Neil Schemenauer06ded092006-08-04 16:20:30 +00001183- Fix a bug in the ``compiler`` package that caused invalid code to be

1199
Thomas Heller86720042006-08-14 11:17:48 +00001200- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1201 uses the _as_parameter_ attribute when objects are passed to foreign
1202 function calls. The ctypes version number was changed to 1.0.1.
1203
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001204- Bug #1530559, struct.pack raises TypeError where it used to convert.
1205 Passing float arguments to struct.pack when integers are expected
1206 now triggers a DeprecationWarning.

Fred Drake53912162006-07-29 13:22:49 +00001251What's New in Python 2.5 beta 3?
1252================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001253
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001254*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001255
1256Core and builtins
1257-----------------
1258
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001259- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001260 returned a long (see PEP 353).
1261
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001262- Bug #1515471: string.replace() accepts character buffers again.
1263
Neal Norwitz07aadb12006-07-30 06:55:48 +00001264- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1265 This provides the proper warning for struct.pack().
1266 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1267
Neal Norwitz0d62a062006-07-30 06:53:31 +00001268- Patch #1531113: Fix augmented assignment with yield expressions.
1269 Also fix a SystemError when trying to assign to yield expressions.
1270
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001271- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1272 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1273 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1274 excessive filesystem operations during imports.
1275
Tim Petersbc24eee2006-07-27 01:14:53 +00001276- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1277 operations on signed longs that are formally undefined by C.
1278 Unfortunately, at least one compiler now cares about that, so complicated
1279 the code to make that compiler happy again.
1280
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001281- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1282
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001283- Patch #1232023: Stop including current directory in search
1284 path on Windows.
1285
Neal Norwitze1fdb322006-07-21 05:32:28 +00001286- Fix some potential crashes found with failmalloc.
1287
Neal Norwitze7563102006-07-17 01:00:16 +00001288- Fix warnings reported by Klocwork's static analysis tool.
1289
Neal Norwitz84be93b2006-07-16 01:50:38 +00001290- Bug #1512814, Fix incorrect lineno's when code within a function
1291 had more than 255 blank lines.
1292
Georg Brandl9dceedb2006-07-12 15:31:17 +00001293- Patch #1521179: Python now accepts the standard options ``--help`` and
1294 ``--version`` as well as ``/?`` on Windows.
1295
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001296- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001297 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001298 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001299
Tim Peters112aad32006-07-19 00:03:19 +00001300- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001301 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001302 new ``sys._current_frames()`` returns a dictionary with one entry,
1303 mapping the faux "thread id" 0 to the current frame.
1304
Ronald Oussoren3075e162006-07-25 20:28:55 +00001305- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001306
Ronald Oussoren3075e162006-07-25 20:28:55 +00001307
Neal Norwitza1f10902006-07-12 07:28:29 +00001308Library
1309-------
1310
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001311- Correction of patch #1455898: In the mbcs decoder, set final=False
1312 for stream decoder, but final=True for the decode function.
1313
Georg Brandl07fec3a2006-08-01 18:49:24 +00001314- os.urandom no longer masks unrelated exceptions like SystemExit or
1315 KeyboardInterrupt.
1316
Tim Peters4643c2f2006-08-10 22:45:34 +00001317- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001318 shutil.copytree on Windows
1319
Georg Brandle34ac7c2006-07-30 11:07:23 +00001320- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1321 refers to file descriptors, not file objects.
1322
Tim Peterscbdd3502006-09-05 01:47:53 +00001323- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001324 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001325 #1513611, and probably others.
1326
Georg Brandledd9b0d2006-07-29 09:33:26 +00001327- Bug #1441397: The compiler module now recognizes module and function
1328 docstrings correctly as it did in Python 2.4.
1329
Tim Peters6f681472006-07-27 23:44:37 +00001330- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1331 lost that tests are sorted by name before being run. This rarely
1332 matters for well-written tests, but can create baffling symptoms if
1333 side effects from one test to the next affect outcomes. ``DocTestFinder``
1334 has been changed to sort the list of tests it returns.
1335
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001336- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001337 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001338
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001339- Bug #978833: Really close underlying socket in _socketobject.close.
1340
Georg Brandldb232dc2006-08-20 13:15:43 +00001341- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1342 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001343
Georg Brandlcf0c1722006-07-26 07:23:32 +00001344- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1345 to recursive calls and call it with the failing package name.
1346
Martin v. Löwis0b483032006-07-25 09:53:12 +00001347- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1348
Georg Brandlc13c34c2006-07-24 14:09:56 +00001349- Patch #1515343: Fix printing of deprecated string exceptions with a
1350 value in the traceback module.
1351
Greg Ward48fae7a2006-07-23 16:05:51 +00001352- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1353
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001354- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1355
Brett Cannoncaebe222006-07-18 04:41:36 +00001356- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1357 argument tuple. For arguments where zero is illegal, the value is forced to
1358 the minimum value that is correct. This is to support an undocumented but
1359 common way people used to fill in inconsequential information in the time
1360 tuple pre-2.4.
1361
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001362- Patch #1220874: Update the binhex module for Mach-O.
1363
Barry Warsawb110bad2006-07-21 14:51:07 +00001364- The email package has improved RFC 2231 support, specifically for
1365 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1366 (name*0=<blah>) parameter continuations. This may change the types of
1367 values returned from email.message.Message.get_param() and friends.
1368 Specifically in some cases where non-encoded continuations were used,
1369 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1370 will just return the string (since non-encoded continuations don't have
1371 charset and language parts).
1372
1373 Also, whereas % values were decoded in all parameter continuations, they are
1374 now only decoded in encoded parameter parts.
1375
Ronald Oussoren3075e162006-07-25 20:28:55 +00001376- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1377
1378- Bug #1517996: IDLE now longer shows the default Tk menu when a
1379 path browser, class browser or debugger is the frontmost window on MacOS X
1380
Barry Warsaw00decd72006-07-27 23:43:15 +00001381- Patch #1520294: Support for getset and member descriptors in types.py,
1382 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1383 of an object against these built-in types and more importantly, for getting
1384 their docstrings printed in the interactive interpreter's help() function.

1388-----------------
1389
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001390- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1391 a socket operation on a socket with a timeout, the exception will be
1392 caught correctly. Previously, the exception was not caught.
1393
Thomas Heller1393d6a2006-07-28 21:43:20 +00001394- Patch #1529514: The _ctypes extension is now compiled on more
1395 openbsd target platforms.
1396
Tim Peters9cab5932006-07-28 00:30:00 +00001397- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1398 a memory leak, affecting pickles and deep copies.
1399
Tim Petersbc24eee2006-07-27 01:14:53 +00001400- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001401 Paul Eggert.
1402
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001403- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1404
Thomas Hellerce049a02006-07-14 17:51:14 +00001405- Patch #1521817: Index range checking on ctypes arrays containing
1406 exactly one element enabled again. This allows iterating over these
1407 arrays, without the need to check the array size before.
1408
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001409- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001410 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001411 /dev/null in certain cases; this is now fixed.
1412
Thomas Heller47d7a062006-07-12 08:43:47 +00001413- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1414 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001415
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001416- Because of a misspelled preprocessor symbol, ctypes was always
1417 compiled without thread support; this is now fixed.
1418
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001419- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1420 methods now allow their database parameter to be None as the
1421 sleepycat API allows.
1422
Matt Flemingec926502006-07-28 11:27:27 +00001423- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1424 bluetooth API compared with Linux and FreeBSD.
1425
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001426Tests
1427-----
1428
1429- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1430 how long the test file should take to play. Now accepts taking 2.93 secs
1431 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1432
Georg Brandl4793aa32006-07-28 18:31:39 +00001433- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1434 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1435 run via ``regrtest.py``. Now they do.

1444
1445- PythonLauncher now works correctly when the path to the script contains
1446 characters that are treated specially by the shell (such as quotes).
1447
1448- Bug #1527397: PythonLauncher now launches scripts with the working directory
1449 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001450 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001451 expect.

1464
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001465- Bug #1501934: The scope of global variables that are locally assigned

Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001474- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1475 omit a default "error" argument for NULL pointer. This allows
1476 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001477
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001478- Bug #1519018: 'as' is now validated properly in import statements.
1479
Neal Norwitz28746ab2006-07-09 22:14:42 +00001480- On 64 bit systems, int literals that use less than 64 bits are
1481 now ints rather than longs.
1482
Neal Norwitzed657552006-07-10 00:04:44 +00001483- Bug #1512814, Fix incorrect lineno's when code at module scope
1484 started after line 256.
1485
Tim Peters32a83612006-07-10 21:08:24 +00001486- New function ``sys._current_frames()`` returns a dict mapping thread
1487 id to topmost thread stack frame. This is for expert use, and is
1488 especially useful for debugging application deadlocks. The functionality
1489 was previously available in Fazal Majid's ``threadframe`` extension
1490 module, but it wasn't possible to do this in a wholly threadsafe way from
1491 an extension.

1508
Thomas Woutersadd19112006-07-05 11:03:49 +00001509- string.Template() now correctly handles tuple-values. Previously,
1510 multi-value tuples would raise an exception and single-value tuples would
1511 be treated as the value they contain, instead.
1512
Martin v. Löwisede77f52006-07-03 13:01:35 +00001513- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1538
Brett Cannon53ab5b72006-06-22 16:49:14 +00001539- Bug #1510580: The 'warnings' module improperly required that a Warning
1540 category be either a types.ClassType and a subclass of Warning. The proper
1541 check is just that it is a subclass with Warning as the documentation states.
1542
Georg Brandlad29e632006-06-21 17:45:17 +00001543- The compiler module now correctly compiles the new try-except-finally
1544 statement (bug #1509132).
1545
Neal Norwitz60373cd2006-06-22 06:30:50 +00001546- The wsgiref package is now installed properly on Unix.

1550
Gerhard Häring762fbd32006-07-02 17:48:30 +00001551- The sqlite3 module did cut off data from the SQLite database at the first
1552 null character before sending it to a custom converter. This has been fixed
1553 now.

1556-----------------
1557
Tim Peters112aad32006-07-19 00:03:19 +00001558- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1559 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1560 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001561
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001562- Assigning None to pointer type fields in ctypes structures possible
1563 overwrote the wrong fields, this is fixed now.
1564
1565- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1566 on non-Windows platforms.
1567
1568- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1569 integer or long, without range checking.
1570
1571- Patch #1517790: It is now possible to use custom objects in the ctypes
1572 foreign function argtypes sequence as long as they provide a from_param
1573 method, no longer is it required that the object is a ctypes type.
1574
1575- The '_ctypes' extension module now works when Python is configured
1576 with the --without-threads option.
1577
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001578- Bug #1513646: os.access on Windows now correctly determines write

1593
Tim Peters32a83612006-07-10 21:08:24 +00001594- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001595 Previously, the slight difference could cause compilation errors of the
1596 'zlib' module on systems with more than one version of zlib.
1597
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001598- The MSI compileall step was fixed to also support a TARGETDIR

1629Core and builtins
1630-----------------
1631
Georg Brandla56b9152006-06-19 06:35:54 +00001632- Patch #1507676: Error messages returned by invalid abstract object operations
1633 (such as iterating over an integer) have been improved and now include the
1634 type of the offending object to help with debugging.
1635
Brett Cannonea3912b2006-06-13 21:46:41 +00001636- Bug #992017: A classic class that defined a __coerce__() method that returned
1637 its arguments swapped would infinitely recurse and segfault the interpreter.
1638
Neal Norwitz909eb122006-06-12 02:13:21 +00001639- Fix the socket tests so they can be run concurrently.
1640
Neal Norwitzb9845e72006-06-12 02:11:18 +00001641- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001642 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001643
Brett Cannon22565aa2006-06-09 22:31:23 +00001644- Bug #532646: object.__call__() will continue looking for the __call__
1645 attribute on objects until one without one is found. This leads to recursion
1646 when you take a class and set its __call__ attribute to an instance of the
1647 class. Originally fixed for classic classes, but this fix is for new-style.
1648 Removes the infinite_rec_3 crasher.
1649
Georg Brandl24250812006-06-09 18:45:48 +00001650- The string and unicode methods startswith() and endswith() now accept
1651 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1652
Brett Cannonde3b0522006-06-08 17:00:45 +00001653- Buffer objects, at the C level, never used the char buffer
1654 implementation even when the char buffer for the wrapped object was
1655 explicitly requested (originally returned the read or write buffer).
1656 Now a TypeError is raised if the char buffer is not present but is
1657 requested.
1658
Georg Brandlddbaa662006-06-04 21:56:52 +00001659- Patch #1346214: Statements like "if 0: suite" are now again optimized
1660 away like they were in Python 2.4.
1661
Georg Brandlb7c8f542006-05-27 12:30:25 +00001662- Builtin exceptions are now full-blown new-style classes instead of
1663 instances pretending to be classes, which speeds up exception handling
1664 by about 80% in comparison to 2.5a2.
1665
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001666- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1667 Unicode 4.1.
1668
Georg Brandlf4ef1162006-05-26 18:03:31 +00001669- Patch #921466: sys.path_importer_cache is now used to cache valid and
1670 invalid file paths for the built-in import machinery which leads to
1671 fewer open calls on startup.
1672
Tim Peters696cf432006-05-24 21:10:40 +00001673- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1674 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1675 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1676 the number of input digits (it was and remains linear-time for bases
1677 2, 4, 8, 16 and 32).
1678
Tim Petersb713ec22006-05-23 18:45:30 +00001679- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1680 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1681 an integer close to ``sys.maxint``. This was repaired by patch
1682 #1335972, which also gives a nice speedup.
1683
Richard Jonescebbefc2006-05-23 18:28:17 +00001684- Patch #1337051: reduced size of frame objects.
1685
1686- PyErr_NewException now accepts a tuple of base classes as its
1687 "base" parameter.
1688
Richard Jones7c88dcc2006-05-23 10:37:38 +00001689- Patch #876206: function call speedup by retaining allocated frame
1690 objects.
1691
Georg Brandl7b90e162006-05-18 07:01:27 +00001692- Bug #1462152: file() now checks more thoroughly for invalid mode
1693 strings and removes a possible "U" before passing the mode to the
1694 C library function.
1695
Neal Norwitz1004a532006-05-15 07:17:23 +00001696- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1697
Neal Norwitz373f0a72006-05-15 07:04:36 +00001698- Bug #1487966: Fix SystemError with conditional expression in assignment
1699
Martin v. Löwis879768d2006-05-11 13:28:43 +00001700- WindowsError now has two error code attributes: errno, which carries
1701 the error values from errno.h, and winerror, which carries the error
1702 values from winerror.h. Previous versions put the winerror.h values
1703 (from GetLastError()) into the errno attribute.
1704
Martin v. Löwis77736712006-05-04 05:51:03 +00001705- Patch #1475845: Raise IndentationError for unexpected indent.
1706
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001707- Patch #1479181: split open() and file() from being aliases for each other.
1708
Tim Peters44bd9862006-06-01 13:49:23 +00001709- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1710 methods were always silently ignored by dictionaries when comparing keys.
1711 They are now passed through (except when using the C API function
1712 ``PyDict_GetItem()``, whose semantics did not change).
1713
1714- Bug #1456209: In some obscure cases it was possible for a class with a
1715 custom ``__eq__()`` method to confuse dict internals when class instances
1716 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1717 No, you don't have any code that did this ;-)

1725
Brett Cannon6ee7d012006-06-08 16:23:04 +00001726- Change binascii.hexlify to accept a read-only buffer instead of only a char
1727 buffer and actually follow its documentation.
1728
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001729- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1730
Nick Coghlanc649ec52006-05-29 12:43:05 +00001731- Patch #1478788 (modified version): The functional extension module has
1732 been renamed to _functools and a functools Python wrapper module added.
1733 This provides a home for additional function related utilities that are
1734 not specifically about functional programming. See PEP 309.
1735
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001736- Patch #1493701: performance enhancements for struct module.

Georg Brandl8d3342b2006-05-16 07:38:27 +00001740- Patch #1435422: zlib's compress and decompress objects now have a
1741 copy() method.
1742
Andrew MacIntyre92913322006-06-13 15:04:24 +00001743- Patch #1454481: thread stack size is now tunable at runtime for thread
1744 enabled builds on Windows and systems with Posix threads support.
1745
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001746- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1747 (up to the system limit of 32K characters).
1748
1749- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1750 As a result, these functions now raise WindowsError instead of OSError.
1751
Tim Peters7a822da2006-05-25 21:50:17 +00001752- ``time.clock()`` on Win64 should use the high-performance Windows
1753 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1754 Windows platforms).
1755
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001756- Calling Tk_Init twice is refused if the first call failed as that
1757 may deadlock.
1758
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001759- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1760 accept it without potentially using an uninitialized pointer.
1761
1762- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1763 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

Gregory P. Smith372b5832006-06-05 18:48:21 +00001769- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1770 parameter is supplied. [SF pybsddb bug #1477863]
1771
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001772- bsddb: the __len__ method of a DB object has been fixed to return correct
1773 results. It could previously incorrectly return 0 in some cases.
1774 Fixes SF bug 1493322 (pybsddb bug 1184012).
1775
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001776- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1777 aborts the db transaction safely when a modifier callback fails.
1778 Fixes SF python patch/bug #1408584.
1779
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001780- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001781 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001782 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1783 database calls that would previously deadlock. [SF python bug #775414]
1784
Vinay Sajip28e57612006-07-01 10:45:20 +00001785- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001786

1807 mime.types file for determining MIME types.
1808
Georg Brandl2605ca82006-06-14 06:08:31 +00001809- Bug #1339007: Shelf objects now don't raise an exception in their
1810 __del__ method when initialization failed.
1811
Martin v. Löwisd8251432006-06-14 05:21:04 +00001812- Patch #1455898: The MBCS codec now supports the incremental mode for
1813 double-byte encodings.
1814
Tim Peters43898b42006-06-14 04:09:25 +00001815- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1816 guarantee that adjacent triples in the return list always describe
1817 non-adjacent blocks. Previously, a pair of matching blocks could end
1818 up being described by multiple adjacent triples that formed a partition
1819 of the matching pair.
1820
Greg Ward0e0c9f42006-06-11 16:24:11 +00001821- Bug #1498146: fix optparse to handle Unicode strings in option help,
1822 description, and epilog.
1823
Greg Wardd1c797e2006-06-11 14:42:41 +00001824- Bug #1366250: minor optparse documentation error.
1825
Greg Ward7f547402006-06-11 00:40:49 +00001826- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1827 clarify docs.
1828
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001829- The wsgiref package has been added to the standard library.
1830
Nick Coghlan676725d2006-06-08 13:54:49 +00001831- The functions update_wrapper() and wraps() have been added to the functools
1832 module. These make it easier to copy relevant metadata from the original
1833 function when writing wrapper functions.
1834
Tim Petersd6a9eef2006-06-05 01:48:21 +00001835- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1836 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001837
Martin v. Löwis3f767792006-06-04 19:36:28 +00001838- Patch #1359618: Speed up charmap encoder by using a trie structure
1839 for lookup.
1840
Tim Petersd609b1a2006-06-02 23:22:51 +00001841- The functions in the ``pprint`` module now sort dictionaries by key
1842 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1843 if and only if its display required more than one line, although that
1844 wasn't documented. The new behavior increases predictability; e.g.,
1845 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1846
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001847- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1848 (thanks for J. J. Lee).
1849
Georg Brandl2b330372006-05-28 20:23:12 +00001850- Patch #1496206: improve urllib2 handling of passwords with respect to
1851 default HTTP and HTTPS ports.
1852
George Yoshidaf3c65de2006-05-28 16:39:09 +00001853- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1854
Bob Ippolito7298f272006-05-23 18:43:47 +00001855- Patch #1281707: speed up gzip.readline.
1856
Georg Brandlb89316f2006-05-17 15:51:16 +00001857- Patch #1180296: Two new functions were added to the locale module:
1858 format_string() to get the effect of "format % items" but locale-aware,
1859 and currency() to format a monetary number with currency sign.
1860
Georg Brandle3a25832006-05-17 14:56:04 +00001861- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1862 and several features added, such as speed and geometry control.
1863
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001864- Patch #1488881: add support for external file objects in bz2 compressed
1865 tarfiles.
1866
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001867- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1868 stdout arguments, making it possible to redirect input and output
1869 for remote debugging.
1870
1871- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1872 a couple of issues, notably handling of long file names using the
1873 GNU LONGNAME extension.
1874
1875- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1876 new flag when ``name`` is already the name of an option flag.
1877
1878- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1879 package.
1880
1881- Patch #1472854: make the rlcompleter.Completer class usable on non-
1882 UNIX platforms.
1883
1884- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1885
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001886- Bug #1472827: correctly escape newlines and tabs in attribute values in
1887 the saxutils.XMLGenerator class.

1923-----------------
1924
Thomas Heller1b046642006-04-18 18:51:06 +00001925- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1926 by converting these apis from macros into exported functions again:
1927
1928 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1929 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1930 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1931 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1932 PyRun_String Py_CompileString
1933
Martin v. Löwis45294a92006-04-18 06:24:08 +00001934- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1935
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001936- All uses of PyStructSequence_InitType have been changed to initialize
1937 the type objects only once, even if the interpreter is initialized
1938 multiple times.
1939
Neal Norwitz61546162006-04-14 05:20:28 +00001940- Bug #1454485, array.array('u') could crash the interpreter. This was
1941 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1942 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1943
1944- Py_UNICODE is unsigned. It was always documented as unsigned, but
1945 due to a bug had a signed value in previous versions.
1946
Tim Peters3a5e8b12006-04-11 01:44:07 +00001947- Patch #837242: ``id()`` of any Python object always gives a positive
1948 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1949 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001950 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001951 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001952
Tim Peters3a5e8b12006-04-11 01:44:07 +00001953 def __hash__(self):
1954 return id(self) # WRONG
1955
1956 because a hash result must be a (short) Python int but it was always
1957 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001958 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001959 was always usable as a hash value before this patch. That's no longer
1960 necessarily so.
1961
1962- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001963 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001964 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001965 #1454844)
1966
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001967- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1968 involving generators that have paused outside of any ``try`` or ``with``
1969 blocks. (In 2.5a1, a paused generator that was part of a reference
1970 cycle could not be garbage collected, regardless of whether it was
1971 paused in a ``try`` or ``with`` block.)

Tim Peters711bf302006-04-25 03:31:36 +00002003- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2004 a doctest to be skipped (the code is not run, and the expected output
2005 or exception is ignored).
2006
Nick Coghlanda2268f2006-04-24 04:37:15 +00002007- Fixed contextlib.nested to cope with exceptions being raised and
2008 caught inside exit handlers.
2009
Greg Wardab05edc2006-04-23 03:47:58 +00002010- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2011 hex, octal, or binary; add ``append_const`` action; keep going if
2012 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2013 added ``epilog`` for better help generation).
2014
Tim Peters21fbd572006-04-21 21:18:10 +00002015- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2016 called from a thread spawned as a side effect of importing a module.
2017
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002018- The pydoc module now supports documenting packages contained in
2019 .zip or .egg files.
2020
2021- The pkgutil module now has several new utility functions, such
2022 as ``walk_packages()`` to support working with packages that are either
2023 in the filesystem or zip files.
2024
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002025- The mailbox module can now modify and delete messages from
2026 mailboxes, in addition to simply reading them. Thanks to Gregory
2027 K. Johnson for writing the code, and to the 2005 Google Summer of
2028 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002029
Tim Petersc7605f22006-04-17 21:12:33 +00002030- The ``__del__`` method of class ``local`` in module ``_threading_local``
2031 returned before accomplishing any of its intended cleanup.
2032
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002033- Patch #790710: Add breakpoint command lists in pdb.

Martin v. Löwis10acfd02006-04-10 12:39:36 +00002071- Patch #1429775: Link extension modules with the shared libpython.
2072
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002073- Fixed a libffi build problem on MIPS systems.
2074
Tim Peters8931ff12006-05-13 23:28:20 +00002075- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2076 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2077 and "%zu" for unsigned integers of type ``size_t``.
2078
Anthony Baxter51bcb682006-04-05 14:51:42 +00002079Tests
2080-----
2081
Nick Coghlanda2268f2006-04-24 04:37:15 +00002082- test_contextlib now checks contextlib.nested can cope with exceptions
2083 being raised and caught inside exit handlers.
2084
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002085- test_cmd_line now checks operation of the -m and -c command switches
2086
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002087- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2088 it separately and by hand. It also wasn't cleaning up its changes to
2089 the current Decimal context.
2090
Thomas Woutersabd08882006-04-26 15:53:30 +00002091- regrtest.py now has a -M option to run tests that test the new limits of
2092 containers, on 64-bit architectures. Running these tests is only sensible
2093 on 64-bit machines with more than two gigabytes of memory. The argument
2094 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +00002102Documentation
2103-------------
2104
Tim Petersb06d28c2006-05-12 01:57:59 +00002105- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2106
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002107- PEP 343: Added Context Types section to the library reference
2108 and attempted to bring other PEP 343 related documentation into
2109 line with the implementation and/or python-dev discussions.
2110
Tim Peters8dc73d22006-04-24 02:03:16 +00002111- Bug #1337990: clarified that ``doctest`` does not support examples
2112 requiring both expected output and an exception.
Anthony Baxter51bcb682006-04-05 14:51:42 +00002113
2114
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002115What's New in Python 2.5 alpha 1?
2116=================================
2117
Anthony Baxterebed3f62006-04-03 15:03:44 +00002118*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002119
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002120Core and builtins
2121-----------------
2122
Nick Coghlan43832302006-04-23 17:04:07 +00002123- PEP 338: -m command line switch now delegates to runpy.run_module
2124 allowing it to support modules in packages and zipfiles
2125
Martin v. Löwisc661b882006-04-20 04:54:23 +00002126- On Windows, .DLL is not an accepted file name extension for
2127 extension modules anymore; extensions are only found if they
2128 end in .PYD.
2129
Martin v. Löwisea62d252006-04-03 10:56:49 +00002130- Bug #1421664: sys.stderr.encoding is now set to the same value as
2131 sys.stdout.encoding.
2132
Neal Norwitz92e212f2006-04-03 04:48:37 +00002133- __import__ accepts keyword arguments.
2134
Georg Brandlccadf842006-03-31 18:54:53 +00002135- Patch #1460496: round() now accepts keyword arguments.
2136
Anthony Baxter262c00a2006-03-30 10:53:17 +00002137- Fixed bug #1459029 - unicode reprs were double-escaped.
2138
Hye-Shik Changd478f342006-03-23 12:32:36 +00002139- Patch #1396919: The system scope threads are reenabled on FreeBSD
2140 5.4 and later versions.
2141
Neal Norwitze98ccf62006-03-23 05:39:47 +00002142- Bug #1115379: Compiling a Unicode string with an encoding declaration
2143 now gives a SyntaxError.
2144
Georg Brandlabd1ff82006-03-18 07:59:59 +00002145- Previously, Python code had no easy way to access the contents of a
2146 cell object. Now, a ``cell_contents`` attribute has been added
2147 (closes patch #1170323).
2148
Tim Peterscf79aac2006-03-16 01:14:46 +00002149- Patch #1123430: Python's small-object allocator now returns an arena to
2150 the system ``free()`` when all memory within an arena becomes unused
2151 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2152 freed. Some applications will see a drop in virtual memory size now,
2153 especially long-running applications that, from time to time, temporarily
2154 use a large number of small objects. Note that when Python returns an
2155 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002156 platform C library will in turn return that memory to the operating system.
2157 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002158 appears to be effective at least on Microsoft C and gcc-based systems.
2159 Thanks to Evan Jones for hard work and patience.
2160
Georg Brandl533ff6f2006-03-08 18:09:27 +00002161- Patch #1434038: property() now uses the getter's docstring if there is
2162 no "doc" argument given. This makes it possible to legitimately use
2163 property() as a decorator to produce a read-only property.
2164
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002165- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2166 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2167 of requiring an int or long in slicing and a few other contexts, enabling
2168 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2169
Neal Norwitz995acdf2006-03-07 05:01:00 +00002170- Fixed various bugs reported by Coverity's Prevent tool.
2171
Brett Cannonbf364092006-03-01 04:25:17 +00002172- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2173 new exception base class, BaseException, which has a new message attribute.
2174 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2175 Raising a string exception now raises a DeprecationWarning.
2176
Thomas Woutersfb609f42006-02-28 16:37:25 +00002177- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2178 explicitly relative, using 'from .module import name' to mean 'from the same
2179 package as this module is in. Imports without dots still default to the
2180 old relative-then-absolute, unless 'from __future__ import
2181 absolute_import' is used.
2182
Brett Cannona7446e32006-02-27 23:39:10 +00002183- Properly check if 'warnings' raises an exception (usually when a filter set
2184 to "error" is triggered) when raising a warning for raising string
2185 exceptions.
2186
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002187- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002188 The name was removed from Include/code.h.
2189
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002190- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002191
Guido van Rossum1968ad32006-02-25 22:38:04 +00002192- Patch 1433928:
2193 - The copy module now "copies" function objects (as atomic objects).
2194 - dict.__getitem__ now looks for a __missing__ hook before raising
2195 KeyError.
2196
Tim Peters84ef21c2006-02-28 20:39:06 +00002197- PEP 343: with statement implemented. Needs ``from __future__ import
2198 with_statement``. Use of 'with' as a variable will generate a warning.
2199 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002200 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002201 The following objects have __context__ methods:
2202 - The built-in file type.
2203 - The thread.LockType type.
2204 - The following types defined by the threading module:
2205 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2206 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002207
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002208- Fix the encodings package codec search function to only search
2209 inside its own package. Fixes problem reported in patch #1433198.
2210
2211 Note: Codec packages should implement and register their own
2212 codec search function. PEP 100 has the details.
2213
Tim Peters9ea89d22006-06-04 03:26:02 +00002214- PEP 353: Using ``Py_ssize_t`` as the index type.
2215
2216- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2217 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2218 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2219 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2220 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002221
Neal Norwitzfc76d632006-01-10 06:03:13 +00002222- Patch #1400181, fix unicode string formatting to not use the locale.
2223 This is how string objects work. u'%f' could use , instead of .
2224 for the decimal point. Now both strings and unicode always use periods.
2225
Neal Norwitz671b9e32006-01-09 07:07:12 +00002226- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2227 configure would break checking curses.h.
2228
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002229- Bug #959576: The pwd module is now builtin. This allows Python to be
2230 built on UNIX platforms without $HOME set.
2231
Neal Norwitzc10978f2005-12-19 06:07:16 +00002232- Bug #1072182, fix some potential problems if characters are signed.
2233
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002234- Bug #889500, fix line number on SyntaxWarning for global declarations.
2235
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002236- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2237
Neal Norwitze7214a12005-12-18 05:03:17 +00002238- Support for converting hex strings to floats no longer works.
2239 This was not portable. float('0x3') now raises a ValueError.
2240
Barry Warsaw2a38a862005-12-18 01:27:35 +00002241- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002242 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002243 is now displayed in interactive prompt banner.
2244
Georg Brandlfa166682005-12-17 21:45:17 +00002245- Implementation of PEP 341 - Unification of try/except and try/finally.
2246 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002247 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002248
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002249- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2250 now encodes backslash correctly.
2251
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002252- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2253
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002254- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002255 and long longs.
2256
Neal Norwitz67715f02005-11-09 06:59:35 +00002257- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002258 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002259 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002260
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002261- Replaced most Unicode charmap codecs with new ones using the
2262 new Unicode translate string feature in the builtin charmap
2263 codec; the codecs were created from the mapping tables available
2264 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2265 encodings now include a mapping for the Apple logo)
2266
Tim Peterse3547fd2005-12-16 23:13:57 +00002267- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002268
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002269- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002270
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002271- A new AST parser implementation was completed. The abstract
2272 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002273 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002274
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002275- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002276 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2277
Neal Norwitz708e51a2005-10-03 04:48:15 +00002278- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2279
Neal Norwitz11bd1192005-10-03 00:54:56 +00002280- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2281 Provide a warning when a directory is passed on the command line.
2282
Neal Norwitz40d37812005-10-02 01:48:49 +00002283- Fix segfault with invalid coding.
2284
2285- SF bug #772896: unknown encoding results in MemoryError.
2286
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002287- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002288 supported a __len__() method which evaluated to False when the iterator
2289 was empty.
2290
Guido van Rossum630db602005-09-20 18:49:54 +00002291- On 64-bit platforms, when __len__() returns a value that cannot be
2292 represented as a C int, raise OverflowError.
2293
Skip Montanarof8948ca2005-09-19 03:54:46 +00002294- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002295 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002296
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002297- SF bug #893549: parsing keyword arguments was broken with a few format
2298 codes.
2299
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002300- Changes donated by Elemental Security to make it work on AIX 5.3
2301 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2302 bug #105470: test_pwd fails on 64bit system (Opteron).
2303
Guido van Rossum539c6622005-09-14 17:49:54 +00002304- Changes donated by Elemental Security to make it work on HP-UX 11 on
2305 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2306
Georg Brandl4550b8d2005-08-26 06:43:52 +00002307- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002308 (fixes bug #1119418).
2309
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002310- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2311
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002312- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2313 exceptions that cause a function to exit.
2314
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002315- The implementation of set() and frozenset() was revised to use its
2316 own internal data structure. Memory consumption is reduced by 1/3
2317 and there are modest speed-ups as well. The API is unchanged.
2318
Tim Petersde7990b2005-07-17 23:45:23 +00002319- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2320
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002321- SF bug #1229429: PyObject_CallMethod failed to decrement some
2322 reference counts in some error exit cases.
2323
Tim Petersecc6e6a2005-07-10 22:30:55 +00002324- SF bug #1185883: Python's small-object memory allocator took over
2325 a block managed by the platform C library whenever a realloc specified
2326 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002327 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002328 portable way to copy data from the C-managed block into Python's
2329 small-object space without risking a memory fault. Python's small-object
2330 realloc now leaves such blocks under the control of the platform C
2331 realloc.
2332
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002333- SF bug #1232517: An overflow error was not detected properly when
2334 attempting to convert a large float to an int in os.utime().
2335
Raymond Hettinger3296e692005-06-29 23:29:56 +00002336- SF bug #1224347: hex longs now print with lowercase letters just
2337 like their int counterparts.
2338
Michael W. Hudson188d4362005-06-20 16:52:57 +00002339- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2340 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2341 interpreter states; back out that fix and do a better job (see
2342 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2343 for a longer write-up of the problem).
2344
Michael W. Hudsondf888462005-06-03 14:41:55 +00002345- SF patch #1180995: marshal now uses a binary format by default when
2346 serializing floats.
2347
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002348- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2349 the routines that promise to produce IEEE 754 binary representations
2350 of floats now simply copy bytes around.
2351
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002352- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2353 278.
2354
Brett Cannonc3647ac2005-04-26 03:45:26 +00002355- patch #1109424: int, long, float, complex, and unicode now check for the
2356 proper magic slot for type conversions when subclassed. Previously the
2357 magic slot was ignored during conversion. Semantics now match the way
2358 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002359 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002360 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002361 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002362
Barry Warsawc8d907c2005-04-19 23:43:40 +00002363- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2364 NULL, now raise an AttributeError when attempting to set or delete the
2365 attribute. Previously a TypeError was raised, but this was inconsistent
2366 with the equivalent pure-Python implementation.
2367
Michael W. Hudson774479c2005-04-18 08:46:17 +00002368- It is now safe to call PyGILState_Release() before
2369 PyEval_InitThreads() (note that if there is reason to believe there
2370 are multiple threads around you still must call PyEval_InitThreads()
2371 before using the Python API; this fix is for extension modules that
2372 have no way of knowing if Python is multi-threaded yet).
2373
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002374- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2375 disabled caused a crash.
2376
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002377- Bug #1165306: instancemethod_new allowed the creation of a method
2378 with im_class == im_self == NULL, which caused a crash when called.
2379
Tim Petersecc6e6a2005-07-10 22:30:55 +00002380- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002381 fixes the crash seen in bug #1165761
2382
Raymond Hettinger96229b12005-03-11 06:49:40 +00002383- Added two new builtins, any() and all().
2384
Brett Cannon409d8f22005-03-05 06:47:57 +00002385- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002386 (e.g., ``class C(): pass`` is no longer a syntax error).
2387 Patch #1176012 added support to the 'parser' module and 'compiler' package
2388 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002389
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002390- Patch #1115086: Support PY_LONGLONG in structmember.
2391
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002392- Bug #1155938: new style classes did not check that __init__() was
2393 returning None.
2394
Tim Petersecc6e6a2005-07-10 22:30:55 +00002395- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002396 ('\') with a specific error message.
2397
Martin v. Löwisff232d72005-03-03 09:24:38 +00002398- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2399
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002400- Bug #1124295: the __name__ attribute of file objects was
2401 inadvertently made inaccessible in restricted mode.
2402
Tim Petersecc6e6a2005-07-10 22:30:55 +00002403- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002404 an ferror() call.
2405
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002406- min() and max() now support key= arguments with the same meaning as in
2407 list.sort().
2408
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002409- The peephole optimizer now performs simple constant folding in expressions:
2410 (2+3) --> (5).
2411
Raymond Hettingera422c342005-01-11 03:03:27 +00002412- set and frozenset objects can now be marshalled. SF #1098985.
2413
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002414- Bug #1077106: Poor argument checking could cause memory corruption
2415 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002416
Jeremy Hyltonab630502005-02-04 18:44:06 +00002417- The parser did not complain about future statements in illegal
2418 positions. It once again reports a syntax error if a future
2419 statement occurs after anything other than a doc string.
2420
Neil Schemenauercf52c072005-08-12 17:34:58 +00002421- Change the %s format specifier for str objects so that it returns a
2422 unicode instance if the argument is not an instance of basestring and
2423 calling __str__ on the argument returns a unicode instance.
2424
Tim Petersf4e69282006-02-27 17:15:31 +00002425- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2426 current thread state when the auto-GIL-state machinery knows about
2427 it (since the thread state is being deleted, continuing to remember it
2428 can't help, but can hurt if another thread happens to get created with
2429 the same thread id).
2430

2459 for applications that require this specific version (such as IDNA).
2460
Neal Norwitzb62c4332006-03-04 18:35:47 +00002461- The timing module is no longer built by default. It was deprecated

Raymond Hettingerb2594052004-12-05 09:25:51 +00002608- itertools.islice() now accepts None for the start and step arguments.
2609 This allows islice() to work more readily with slices:
2610 islice(s.start, s.stop, s.step)
2611

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002621- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2622 been renamed to have only a single underscore prefix. This was done to
2623 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002624
Nick Coghlan43832302006-04-23 17:04:07 +00002625- PEP 338: new module runpy defines a run_module function to support
2626 executing modules which provide access to source code or a code object
2627 via the PEP 302 import mechanisms.
2628
Anthony Baxter93f5b932006-04-03 08:05:07 +00002629- The email module's parsedate_tz function now sets the daylight savings

2637 in attribute values.
2638
Anthony Baxterc51ee692006-04-01 00:57:31 +00002639- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002640 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002641 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002642 module will not be built.
2643
Tim Petersc17976e2006-04-01 00:26:53 +00002644- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2645 aren't officially supported here, and trying to use them will probably
2646 raise an exception some day. But dicts have been allowed, and "mostly
2647 worked", so support for them won't go away without warning.
2648
Georg Brandl338ef7d2006-03-31 18:42:16 +00002649- Bug #1445068: getpass.getpass() can now be given an explicit stream
2650 argument to specify where to write the prompt.
2651

2667
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002668- email 4.0 package now integrated. This is largely the same as the email 3.0
2669 package that was included in Python 2.3, except that PEP 8 module names are
2670 now used (e.g. mail.message instead of email.Message). The MIME classes
2671 have been moved to a subpackage (e.g. email.mime.text instead of
2672 email.MIMEText). The old names are still supported for now. Several
2673 deprecated Message methods have been removed and lots of bugs have been
2674 fixed. More details can be found in the email package documentation.
2675
Walter Dörwald40108c92006-03-27 08:15:44 +00002676- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2677 (a subclass of tuple) that provides incremental decoders and encoders
2678 (a way to use stateful codecs without the stream API). Python functions
2679 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2680 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2681 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002682
Walter Dörwald067db482006-03-15 22:17:27 +00002683- Patch #1359365: Calling next() on a closed StringIO.String object raises
2684 a ValueError instead of a StopIteration now (like file and cString.String do).
2685 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2686 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002687
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002688- A regrtest option -w was added to re-run failed tests in verbose mode.

Tim Peterse3547fd2005-12-16 23:13:57 +00002760 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2761 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2762 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2763 Ronald L. Rivest offered this advice for Python:
2764
2765 "The consensus of researchers in this area (at least as
2766 expressed at the NIST Hash Function Workshop 10/31/05),
2767 is that SHA-256 is a good choice for the time being, but
2768 that research should continue, and other alternatives may
2769 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002770
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002771- Added a subset of Fredrik Lundh's ElementTree package. Available

Raymond Hettinger68c04532005-06-10 11:05:19 +00002868 the generate_tokens() function now accepts a callable argument that
2869 terminates by raising StopIteration.
2870
Georg Brandl9166e1a2005-06-04 09:20:03 +00002871- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2872
Georg Brandl268e61c2005-06-03 14:28:50 +00002873- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2874 component of the path.
2875
Skip Montanaro174dd222005-05-14 20:54:16 +00002876- Patch #1120353: The xmlrpclib module provides better, more transparent,
2877 support for datetime.{datetime,date,time} objects. With use_datetime set
2878 to True, applications shouldn't have to fiddle with the DateTime wrapper
2879 class at all.
2880
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002881- distutils.commands.upload was added to support uploading distribution
2882 files to PyPI.
2883
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002884- distutils.commands.register now encodes the data as UTF-8 before posting
2885 them to PyPI.
2886
Raymond Hettinger267b8682005-03-27 10:47:39 +00002887- decimal operator and comparison methods now return NotImplemented
2888 instead of raising a TypeError when interacting with other types. This
2889 allows other classes to implement __radd__ style methods and have them
2890 work as expected.
2891
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002892- Bug #1163325: Decimal infinities failed to hash. Attempting to
2893 hash a NaN raised an InvalidOperation instead of a TypeError.
2894
Tim Petersecc6e6a2005-07-10 22:30:55 +00002895- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002896 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2897
Martin v. Löwis00a73e72005-03-04 19:40:34 +00002898- Patch #1043890: Add extractall method to tarfile.

Martin v. Löwisc72dd382005-03-04 13:50:17 +00002900- Patch #1075887: Don't require MSVC in distutils if there is nothing
2901 to build.
2902
Martin v. Löwis637431b2005-03-03 23:12:42 +00002903- Patch #1103407: Properly deal with tarfile iterators when untarring
2904 symbolic links on Windows.
2905
Tim Petersecc6e6a2005-07-10 22:30:55 +00002906- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +00002907 profile.py if available.
2908
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00002909- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
2910
Martin v. Löwisc5574e82005-03-03 10:57:37 +00002911- Patch #1117454: Remove code to special-case cookies without values
2912 in LWPCookieJar.
2913
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00002914- Patch #1117339: Add cookielib special name tests.
2915
Martin v. Löwise869eb12005-03-03 09:46:07 +00002916- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
2917
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00002918- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
2919
Martin v. Löwisdf241532005-03-03 08:17:42 +00002920- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
2921
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00002922- Patch #1104111: Alter setup.py --help and --help-commands.
2923
Martin v. Löwis4afe1542005-03-01 08:09:28 +00002924- Patch #1121234: Properly cleanup _exit and tkerror commands.
2925
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00002926- Patch #1049151: xdrlib now unpacks booleans as True or False.
2927
Raymond Hettingerbab41432005-02-05 01:31:19 +00002928- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2929
Guido van Rossumd0641422005-02-03 15:01:24 +00002930- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2931 disables recursive traversal through instance attributes, which can
2932 be exploited in various ways.
2933
Tim Peterse3547fd2005-12-16 23:13:57 +00002934- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002935 flags on the HTTP listening socket.
2936
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002937- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2938 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2939
Fred Drakefbdeaad2006-07-29 16:56:15 +00002940- Patches #893642, #1039083: add allow_none, encoding arguments to
2941 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002942
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002943- Bug #1110478: Revert os.environ.update to do putenv again.
2944
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002945- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2946
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002947- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2948
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002949- Enhancements to the csv module:
2950
2951 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002952 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002953 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002954 + Dialect parameter parsing has been re-implemented to improve error
2955 reporting.
2956 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2957 dictates.
2958 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002959 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002960 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002961 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2962 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002963 + reader now allows \r characters to be quoted (previously it only allowed
2964 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002965 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002966 + Dialect classes passed to the module are no longer instantiated by
2967 the module before being parsed (the former validation scheme required
2968 this, but the mechanism was unreliable).
2969 + The dialect registry now contains instances of the internal
2970 C-coded dialect type, rather than references to python objects.
2971 + the internal c-coded dialect type is now immutable.
2972 + register_dialect now accepts the same keyword dialect specifications
2973 as the reader and writer, allowing the user to register dialects
2974 without first creating a dialect class.
2975 + a configurable limit to the size of parsed fields has been added -
2976 previously, an unmatched quote character could result in the entire
2977 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002978 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002979 the parser field size limit (returning the former limit). The initial
2980 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002981 + A line_num attribute has been added to the reader object, which tracks
2982 the number of lines read from the source iterator. This is not
2983 the same as the number of records returned, as records can span
2984 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002985 + reader and writer objects were not being registered with the cyclic-GC.
2986 This has been fixed.
2987
Brett Cannone6539c42005-01-08 02:43:53 +00002988- _DummyThread objects in the threading module now delete self.__block that is
2989 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2990 lock primitives tend to be limited in number and thus should not be wasted on
2991 a _DummyThread object. Fixes bug #1089632.
2992
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002993- The imghdr module now detects Exif files.
2994
Raymond Hettinger6065d322004-12-20 23:51:53 +00002995- StringIO.truncate() now correctly adjusts the size attribute.
2996 (Bug #951915).
2997
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002998- locale.py now uses an updated locale alias table (built using
2999 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3000 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003001 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003002
Raymond Hettinger3557f422004-12-07 12:02:02 +00003003- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3004
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003005- the pickle module no longer accepts the deprecated None option in the
3006 args tuple returned by __reduce__().
3007
Brett Cannon84667c02004-12-07 03:25:18 +00003008- optparse now optionally imports gettext. This allows its use in setup.py.
3009
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003010- the pickle module no longer uses the deprecated bin parameter.
3011
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003012- the shelve module no longer uses the deprecated binary parameter.
3013
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003014- the pstats module no longer uses the deprecated ignore() method.
3015
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003016- the filecmp module no longer uses the deprecated use_statcache argument.
3017
Raymond Hettinger664347b2004-12-04 21:21:53 +00003018- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3019 extended or overridden by subclasses. Formerly, the subclassed method would
3020 be ignored by the rest of the module. (Bug #1078905).
3021
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003022- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003023 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003024
Walter Dörwald36733692004-12-22 12:50:50 +00003025- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3026 once when a size argument is given. This prevents a buffer overflow in the
3027 tokenizer with very long source lines.
3028
Barry Warsaw538561e2006-01-01 21:48:54 +00003029- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3030 immediately after creating the object, without any intervening
3031 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003032
Skip Montanaro05885812005-01-16 20:48:27 +00003033- The reconvert.quote function can now emit triple-quoted strings. The
3034 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003035
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003036- ``UserString.MutableString`` now supports negative indices in
3037 ``__setitem__`` and ``__delitem__``
3038
Greg Ward40407942005-03-05 02:53:17 +00003039- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3040 correctly.
3041
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003042- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3043 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3044 character even if the user has passed a size parameter to get a proper
3045 line ending. Remove the special handling of a "\r\n" that has been split
3046 between two lines.
3047
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003048- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3049 about illegal code points. The codec now supports PEP 293 style error
3050 handlers.
3051
Walter Dörwald78a78b02005-09-01 12:04:29 +00003052- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003053 from the input stream, so that the output is a byte string in the correct
3054 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003055
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003056- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3057 considering it exactly like a '*'.
3058
Walter Dörwald007f8df2005-10-09 19:42:27 +00003059- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3060 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003061
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003062- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3063
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003064- Patch #1413711: Certain patterns of differences were making difflib
3065 touch the recursion limit.
3066
Walter Dörwald58917a62006-03-31 15:26:22 +00003067- Bug #947906: An object oriented interface has been added to the calendar
3068 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003069 called as a script (e.g. via ``python -mcalendar``). Localized month and
3070 weekday names can be ouput (even if an exotic encoding is used) using
3071 special classes that use unicode.

3082
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003083- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3084
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003085- Patch #881820: look for openpty and forkpty also in libbsd.
3086
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003087- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3088 The zlib module is now builtin on Windows.
3089
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003090- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3091
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003092- Bug #1189330: configure did not correctly determine the necessary
3093 value of LINKCC if python was built with GCC 4.0.
3094
Trent Mick8321b422005-07-26 02:29:21 +00003095- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3096 vulnerability in zlib 1.2.1 and 1.2.2.
3097
Brett Cannon08cd5982005-04-24 22:26:38 +00003098- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3099 flags that change binary compatibility. Changes were also made to
3100 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003101 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003102
Bob Ippolitoed233462005-03-29 13:47:59 +00003103- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3104 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3105 no longer exists). This configure patch makes things right.
3106
Martin v. Löwise2713be2005-03-08 15:03:08 +00003107- Bug #1158607: Build with --disable-unicode again.
3108
Brett Cannon46d96232005-02-16 00:07:19 +00003109- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3110 defined. Discovered as a result of not being able to build on OS X.
3111
Brett Cannon516592f2004-12-07 00:42:59 +00003112- setup.py now uses the directories specified in LDFLAGS using the -L option
3113 and in CPPFLAGS using the -I option for adding library and include
3114 directories, respectively, for compiling extension modules against. This has
3115 led to the core being compiled using the values in CPPFLAGS. It also removes
3116 the need for the special-casing of both DarwinPorts and Fink for darwin since
3117 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3118 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3119 Fink, ``-I/opt/local/include`` for DarwinPorts).
3120
Brett Cannon43802422005-02-10 20:48:03 +00003121- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3122 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3123 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3124 Closes bug #1096244. Thanks Gregory Bond.

Tim Petersc9d78aa2006-03-26 23:27:58 +00003129- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3130 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3131 is obtained via the ``PyObject_`` family, it must be released via the
3132 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3133 always been officially true, but when Python's small-object allocator was
3134 introduced, an attempt was made to cater to a few extension modules
3135 discovered at the time that obtained memory via ``PyObject_New`` but
3136 released it via ``PyMem_DEL``. It's years later, and if such code still
3137 exists it will fail now (probably with segfaults, but calling wrong
3138 low-level memory management functions can yield many symptoms).

Raymond Hettingerbeb31012005-08-16 03:47:52 +00003140- Added a C API for set and frozenset objects.

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003144- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3145 mapping argument now. This string is used as a mapping table. Byte values
3146 greater than the length of the string and 0xFFFE are treated as undefined
3147 mappings.
