Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +000014
Guido van Rossumaa975432008-04-10 22:43:58 +000015- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
16 having a self-referential tuple, which is possible from C code. Nor did
17 object's tp_str consider that a type's tp_str could do something that could
18 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
19 respectively, fixed the issues. (Backport of r58288 from trunk.)
20
Georg Brandld9f1da02008-03-29 01:50:46 +000021- Patch #1442: properly report exceptions when the PYTHONSTARTUP file
22 cannot be executed.
23
Amaury Forgeot d'Arc8432d862008-03-28 20:45:42 +000024- The compilation of a class nested in another class used to leak one
25 reference on the outer class name.
26
Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +000027- Issue #1477: With narrow Unicode builds, the unicode escape sequence
28 \Uxxxxxxxx did not accept values outside the Basic Multilingual Plane. This
29 affected raw unicode literals and the 'raw-unicode-escape' codec. Now
30 UTF-16 surrogates are generated in this case, like normal unicode literals
31 and the 'unicode-escape' codec.
32
Neal Norwitzb3635f92008-03-18 04:17:36 +000033- Issue #2321: use pymalloc for unicode object string data to reduce
34 memory usage in some circumstances.
Andrew M. Kuchlingbe0adfc2008-02-23 17:18:19 +000035
Sean Reifscheider4af861c2008-03-20 17:39:31 +000036- Issue #2238: Some syntax errors in *args and **kwargs expressions could give
37 bogus error messages.
38
Gregory P. Smith14acde32008-04-09 23:41:13 +000039- Issue #2587: In the C API, PyString_FromStringAndSize() takes a signed size
40 parameter but was not verifying that it was greater than zero. Values
41 less than zero will now raise a SystemError and return NULL to indicate a
42 bug in the calling C code.

52 handlers that derive the same default base class.
53
Amaury Forgeot d'Arc198e3532008-03-27 23:41:59 +000054- Issue #2495: tokenize.untokenize now inserts a space between two consecutive
55 string literals; previously, ["" ""] was rendered as [""""], which is
56 incorrect python code.
57
Mark Dickinsonbfdbfd42008-03-25 18:58:13 +000058- Issue #2482: Make sure that the coefficient of a Decimal is always
59 stored as a str instance, not as a unicode instance. This ensures
60 that str(Decimal) is always an instance of str. This fixes a
61 regression from Python 2.5.1 to Python 2.5.2.
62

66 advertised in the docs.
67
Gregory P. Smitheff5a4e2008-03-18 19:24:40 +000068- Issue #1747858: Fix chown to work with large uid's and gid's on 64-bit

72
Martin v. Löwis0e305552008-03-06 07:14:26 +000073- Bug #1725737: In distutil's sdist, exclude RCS, CVS etc. also in the
74 root directory, and also exclude .hg, .git, .bzr, and _darcs.
75
Andrew M. Kuchling37d4f7b2008-02-23 19:06:54 +000076- Bug #1389051: imaplib causes excessive memory fragmentation when reading
77 large messages.

135-----------------
136
Martin v. Löwis73c01d42008-02-14 11:26:18 +0000137- Added checks for integer overflows, contributed by Google. Some are
138 only available if asserts are left in the code, in cases where they

143
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000144- Issue #1920: "while 0" statements were completely removed by the compiler,
145 even in the presence of an "else" clause, which is supposed to be run when

963-----------------
964
Neal Norwitz0bcafac2006-09-11 08:51:17 +0000965- Make _PyGILState_NoteThreadState() static, it was not used anywhere
966 outside of pystate.c and should not be necessary.
967
Brett Cannon19d76c52006-09-09 07:18:44 +0000968- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
969 allows calling unicode() on exceptions classes directly to succeed.
970
Georg Brandlecab6232006-09-06 06:47:02 +0000971- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
972 Also make sure that every exception class has __module__ set to
973 'exceptions'.
974
Georg Brandl37a9e572006-09-06 06:09:34 +0000975- Bug #1550983: emit better error messages for erroneous relative

985
Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000986- The return tuple from str.rpartition(sep) is (tail, sep, head) where
987 head is the original string if sep was not found.
988
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000989- Bug #1520864: unpacking singleton tuples in list comprehensions and
990 generator expressions (x for x, in ... ) works again. Fixing this problem
991 required changing the .pyc magic number. This means that .pyc files
992 generated before 2.5c2 will be regenerated.

1106
Neal Norwitz24b6f202006-09-05 04:43:56 +00001107- Fix infinite recursion when subclassing long and overriding __hash__.
1108
1109- Fix concatenation (+=) of long strings.
1110
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001111- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001112 compared equal or unequal to a string and a UnicodeDecodeError
1113 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001114
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001115 Instead, the equal (==) and unequal (!=) comparison operators will
1116 now issue a UnicodeWarning and interpret the two objects as
1117 unequal. The UnicodeWarning can be filtered as desired using
1118 the warning framework, e.g. silenced completely, turned into an
1119 exception, logged, etc.
1120
1121 Note that compare operators other than equal and unequal will still
1122 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001123
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001124- Fix segfault when doing string formatting on subclasses of long.
1125
1126- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1127 with new-style classes.
1128
1129- Fix bug related to __len__ functions returning negative values with
1130 classic classes.
1131
1132- Patch #1538606, Fix __index__() clipping. There were some problems
1133 discovered with the API and how integers that didn't fit into Py_ssize_t
1134 were handled. This patch attempts to provide enough alternatives
1135 to effectively use __index__.
1136
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001137- Bug #1536021: __hash__ may now return long int; the final hash
1138 value is obtained by invoking hash on the long int.
1139
Thomas Hellerab1049c2006-08-08 17:37:00 +00001140- Bug #1536786: buffer comparison could emit a RuntimeWarning.

1143 sys.stdin is closed.
1144
Thomas Heller74d36f02006-08-04 18:17:40 +00001145- On Windows, the PyErr_Warn function is now exported from
1146 the Python dll again.
1147
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001148- Bug #1191458: tracing over for loops now produces a line event
1149 on each iteration. Fixing this problem required changing the .pyc
1150 magic number. This means that .pyc files generated before 2.5c1
1151 will be regenerated.
1152
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001153- Bug #1333982: string/number constants were inappropriately stored
1154 in the byte code and co_consts even if they were not used, ie
1155 immediately popped off the stack.
1156
Georg Brandle9462c72006-08-04 18:03:37 +00001157- Fixed a reference-counting problem in property().

1161-------
1162
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001163- Fix a bug in the ``compiler`` package that caused invalid code to be
1164 generated for generator expressions.
1165
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001166- The distutils version has been changed to 2.5.0. The change to
1167 keep it programmatically in sync with the Python version running
1168 the code (introduced in 2.5b3) has been reverted. It will continue
1169 to be maintained manually as static string literal.
1170
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001171- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001172 and this cannot be converted to the required C type, an exception is
1173 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001174 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001175
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001176- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001177 an exception.
1178
Tim Peterscbdd3502006-09-05 01:47:53 +00001179- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001180 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001181 workarounds for clocks with low resolution, to stop the code yielding
1182 duplicate UUIDs.
1183
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001184- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1185 before raising SystemExit, allowing IDLE to honor quit() and exit().
1186

1198 str(exception) raised an exception.
1199
Neil Schemenauer06ded092006-08-04 16:20:30 +00001200- Fix a bug in the ``compiler`` package that caused invalid code to be

Thomas Heller1ce433e2006-08-14 16:20:04 +00001214- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1215 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1216
Thomas Heller86720042006-08-14 11:17:48 +00001217- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1218 uses the _as_parameter_ attribute when objects are passed to foreign
1219 function calls. The ctypes version number was changed to 1.0.1.
1220
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001221- Bug #1530559, struct.pack raises TypeError where it used to convert.
1222 Passing float arguments to struct.pack when integers are expected
1223 now triggers a DeprecationWarning.

1258-----
1259
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001260- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1261
Tim Peters4643c2f2006-08-10 22:45:34 +00001262- Bug #1069160. Internal correctness changes were made to
1263 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1264 the documentation was changed to state that the return value
1265 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001268What's New in Python 2.5 beta 3?
1269================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001270
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001271*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001272
1273Core and builtins
1274-----------------
1275
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001276- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001277 returned a long (see PEP 353).
1278
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001279- Bug #1515471: string.replace() accepts character buffers again.
1280
Neal Norwitz07aadb12006-07-30 06:55:48 +00001281- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1282 This provides the proper warning for struct.pack().
1283 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1284
Neal Norwitz0d62a062006-07-30 06:53:31 +00001285- Patch #1531113: Fix augmented assignment with yield expressions.
1286 Also fix a SystemError when trying to assign to yield expressions.
1287
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001288- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1289 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1290 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1291 excessive filesystem operations during imports.
1292
Tim Petersbc24eee2006-07-27 01:14:53 +00001293- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1294 operations on signed longs that are formally undefined by C.
1295 Unfortunately, at least one compiler now cares about that, so complicated
1296 the code to make that compiler happy again.
1297
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001298- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1299
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001300- Patch #1232023: Stop including current directory in search
1301 path on Windows.
1302
Neal Norwitze1fdb322006-07-21 05:32:28 +00001303- Fix some potential crashes found with failmalloc.
1304
Neal Norwitze7563102006-07-17 01:00:16 +00001305- Fix warnings reported by Klocwork's static analysis tool.
1306
Neal Norwitz84be93b2006-07-16 01:50:38 +00001307- Bug #1512814, Fix incorrect lineno's when code within a function
1308 had more than 255 blank lines.
1309
Georg Brandl9dceedb2006-07-12 15:31:17 +00001310- Patch #1521179: Python now accepts the standard options ``--help`` and
1311 ``--version`` as well as ``/?`` on Windows.
1312
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001313- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001314 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001315 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001316
Tim Peters112aad32006-07-19 00:03:19 +00001317- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001318 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001319 new ``sys._current_frames()`` returns a dictionary with one entry,
1320 mapping the faux "thread id" 0 to the current frame.
1321
Ronald Oussoren3075e162006-07-25 20:28:55 +00001322- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001323
Ronald Oussoren3075e162006-07-25 20:28:55 +00001324
Neal Norwitza1f10902006-07-12 07:28:29 +00001325Library
1326-------
1327
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001328- Correction of patch #1455898: In the mbcs decoder, set final=False
1329 for stream decoder, but final=True for the decode function.
1330
Georg Brandl07fec3a2006-08-01 18:49:24 +00001331- os.urandom no longer masks unrelated exceptions like SystemExit or
1332 KeyboardInterrupt.
1333
Tim Peters4643c2f2006-08-10 22:45:34 +00001334- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001335 shutil.copytree on Windows
1336
Georg Brandle34ac7c2006-07-30 11:07:23 +00001337- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1338 refers to file descriptors, not file objects.
1339
Tim Peterscbdd3502006-09-05 01:47:53 +00001340- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001341 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001342 #1513611, and probably others.
1343
Georg Brandledd9b0d2006-07-29 09:33:26 +00001344- Bug #1441397: The compiler module now recognizes module and function
1345 docstrings correctly as it did in Python 2.4.
1346
Tim Peters6f681472006-07-27 23:44:37 +00001347- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1348 lost that tests are sorted by name before being run. This rarely
1349 matters for well-written tests, but can create baffling symptoms if
1350 side effects from one test to the next affect outcomes. ``DocTestFinder``
1351 has been changed to sort the list of tests it returns.
1352
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001353- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001354 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001355
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001356- Bug #978833: Really close underlying socket in _socketobject.close.
1357
Georg Brandldb232dc2006-08-20 13:15:43 +00001358- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1359 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001360
Georg Brandlcf0c1722006-07-26 07:23:32 +00001361- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1362 to recursive calls and call it with the failing package name.
1363
Martin v. Löwis0b483032006-07-25 09:53:12 +00001364- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1365
Georg Brandlc13c34c2006-07-24 14:09:56 +00001366- Patch #1515343: Fix printing of deprecated string exceptions with a
1367 value in the traceback module.
1368
Greg Ward48fae7a2006-07-23 16:05:51 +00001369- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1370
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001371- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1372
Brett Cannoncaebe222006-07-18 04:41:36 +00001373- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1374 argument tuple. For arguments where zero is illegal, the value is forced to
1375 the minimum value that is correct. This is to support an undocumented but
1376 common way people used to fill in inconsequential information in the time
1377 tuple pre-2.4.
1378
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001379- Patch #1220874: Update the binhex module for Mach-O.
1380
Barry Warsawb110bad2006-07-21 14:51:07 +00001381- The email package has improved RFC 2231 support, specifically for
1382 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1383 (name*0=<blah>) parameter continuations. This may change the types of
1384 values returned from email.message.Message.get_param() and friends.
1385 Specifically in some cases where non-encoded continuations were used,
1386 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1387 will just return the string (since non-encoded continuations don't have
1388 charset and language parts).
1389
1390 Also, whereas % values were decoded in all parameter continuations, they are
1391 now only decoded in encoded parameter parts.
1392
Ronald Oussoren3075e162006-07-25 20:28:55 +00001393- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1394
1395- Bug #1517996: IDLE now longer shows the default Tk menu when a
1396 path browser, class browser or debugger is the frontmost window on MacOS X
1397
Barry Warsaw00decd72006-07-27 23:43:15 +00001398- Patch #1520294: Support for getset and member descriptors in types.py,
1399 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1400 of an object against these built-in types and more importantly, for getting
1401 their docstrings printed in the interactive interpreter's help() function.

1405-----------------
1406
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001407- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1408 a socket operation on a socket with a timeout, the exception will be
1409 caught correctly. Previously, the exception was not caught.
1410
Thomas Heller1393d6a2006-07-28 21:43:20 +00001411- Patch #1529514: The _ctypes extension is now compiled on more
1412 openbsd target platforms.
1413
Tim Peters9cab5932006-07-28 00:30:00 +00001414- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1415 a memory leak, affecting pickles and deep copies.
1416
Tim Petersbc24eee2006-07-27 01:14:53 +00001417- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001418 Paul Eggert.
1419
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001420- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1421
Thomas Hellerce049a02006-07-14 17:51:14 +00001422- Patch #1521817: Index range checking on ctypes arrays containing
1423 exactly one element enabled again. This allows iterating over these
1424 arrays, without the need to check the array size before.
1425
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001426- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001427 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001428 /dev/null in certain cases; this is now fixed.
1429
Thomas Heller47d7a062006-07-12 08:43:47 +00001430- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1431 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001432
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001433- Because of a misspelled preprocessor symbol, ctypes was always
1434 compiled without thread support; this is now fixed.
1435
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001436- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1437 methods now allow their database parameter to be None as the
1438 sleepycat API allows.
1439
Matt Flemingec926502006-07-28 11:27:27 +00001440- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1441 bluetooth API compared with Linux and FreeBSD.

Brett Cannonf23ad3d2006-07-25 17:32:20 +00001443Tests
1444-----
1445
1446- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1447 how long the test file should take to play. Now accepts taking 2.93 secs
1448 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1449
Georg Brandl4793aa32006-07-28 18:31:39 +00001450- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1451 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1452 run via ``regrtest.py``. Now they do.

1461
1462- PythonLauncher now works correctly when the path to the script contains
1463 characters that are treated specially by the shell (such as quotes).
1464
1465- Bug #1527397: PythonLauncher now launches scripts with the working directory
1466 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001467 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001468 expect.

1476Core and builtins
1477-----------------
1478
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001479- Bug #1441486: The literal representation of -(sys.maxint - 1)
1480 again evaluates to a int object, not a long.
1481
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001482- Bug #1501934: The scope of global variables that are locally assigned
1483 using augmented assignment is now correctly determined.
1484
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001485- Bug #927248: Recursive method-wrapper objects can now safely
1486 be released.
1487
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001488- Bug #1417699: Reject locale-specific decimal point in float()
1489 and atof().
1490
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001491- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1492 omit a default "error" argument for NULL pointer. This allows
1493 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001494
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001495- Bug #1519018: 'as' is now validated properly in import statements.
1496
Neal Norwitz28746ab2006-07-09 22:14:42 +00001497- On 64 bit systems, int literals that use less than 64 bits are
1498 now ints rather than longs.
1499
Neal Norwitzed657552006-07-10 00:04:44 +00001500- Bug #1512814, Fix incorrect lineno's when code at module scope
1501 started after line 256.
1502
Tim Peters32a83612006-07-10 21:08:24 +00001503- New function ``sys._current_frames()`` returns a dict mapping thread
1504 id to topmost thread stack frame. This is for expert use, and is
1505 especially useful for debugging application deadlocks. The functionality
1506 was previously available in Fazal Majid's ``threadframe`` extension
1507 module, but it wasn't possible to do this in a wholly threadsafe way from
1508 an extension.
1509

1511-------
1512
Martin v. Löwis77621582006-07-30 13:27:31 +00001513- Bug #1257728: Mention Cygwin in distutils error message about a missing
1514 VS 2003.
1515
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001516- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1517
Tim Peters32a83612006-07-10 21:08:24 +00001518- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001519 environment variable to be set in order to the SDK environment
1520 for finding the compiler, include files, etc.
1521
Martin v. Löwis388a8c22006-07-06 19:28:03 +00001522- Bug #1515998: Properly generate logical ids for files in bdist_msi.
1523
Nick Coghlan2d792252006-07-06 13:47:18 +00001524- warnings.py now ignores ImportWarning by default
1525
Thomas Woutersadd19112006-07-05 11:03:49 +00001526- string.Template() now correctly handles tuple-values. Previously,
1527 multi-value tuples would raise an exception and single-value tuples would
1528 be treated as the value they contain, instead.
1529
Martin v. Löwisede77f52006-07-03 13:01:35 +00001530- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1531 even if some data are received.
1532
Martin v. Löwis45482392006-07-03 12:28:58 +00001533- Bug #1267547: Put proper recursive setup.py call into the
1534 spec file generated by bdist_rpm.
1535
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001536- Bug #1514693: Update turtle's heading when switching between
1537 degrees and radians.
1538
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001539- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001540 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001541
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001542- Bug #1514703: Only setup canvas window in turtle when the canvas
1543 is created.
1544
Martin v. Löwis7596e832006-07-01 15:33:37 +00001545- Bug #1513223: .close() of a _socketobj now releases the underlying
1546 socket again, which then gets closed as it becomes unreferenced.

1549 attribute values.
1550
1551- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1552 sgmllib ('[' and ']' were not accepted).
1553
Georg Brandl1be63af2006-06-28 20:23:25 +00001554- Fix a bug in the turtle module's end_fill function.
1555
Brett Cannon53ab5b72006-06-22 16:49:14 +00001556- Bug #1510580: The 'warnings' module improperly required that a Warning
1557 category be either a types.ClassType and a subclass of Warning. The proper
1558 check is just that it is a subclass with Warning as the documentation states.
1559
Georg Brandlad29e632006-06-21 17:45:17 +00001560- The compiler module now correctly compiles the new try-except-finally
1561 statement (bug #1509132).
1562
Neal Norwitz60373cd2006-06-22 06:30:50 +00001563- The wsgiref package is now installed properly on Unix.
1564
Vinay Sajip28e57612006-07-01 10:45:20 +00001565- A bug was fixed in logging.config.fileConfig() which caused a crash on
1566 shutdown when fileConfig() was called multiple times.
1567
Gerhard Häring762fbd32006-07-02 17:48:30 +00001568- The sqlite3 module did cut off data from the SQLite database at the first
1569 null character before sending it to a custom converter. This has been fixed
1570 now.
1571
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001572Extension Modules
1573-----------------
1574
Tim Peters112aad32006-07-19 00:03:19 +00001575- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1576 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1577 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001578
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001579- Assigning None to pointer type fields in ctypes structures possible
1580 overwrote the wrong fields, this is fixed now.
1581
1582- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1583 on non-Windows platforms.
1584
1585- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1586 integer or long, without range checking.
1587
1588- Patch #1517790: It is now possible to use custom objects in the ctypes
1589 foreign function argtypes sequence as long as they provide a from_param
1590 method, no longer is it required that the object is a ctypes type.
1591
1592- The '_ctypes' extension module now works when Python is configured
1593 with the --without-threads option.
1594
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001595- Bug #1513646: os.access on Windows now correctly determines write
1596 access, again.
1597
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001598- Bug #1512695: cPickle.loads could crash if it was interrupted with
1599 a KeyboardInterrupt.
1600
Neal Norwitza12aa882006-07-06 06:45:08 +00001601- Bug #1296433: parsing XML with a non-default encoding and
1602 a CharacterDataHandler could crash the interpreter in pyexpat.
1603
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001604- Patch #1516912: improve Modules support for OpenVMS.
1605
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001606Build
1607-----
1608
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001609- Automate Windows build process for the Win64 SSL module.
1610
Tim Peters32a83612006-07-10 21:08:24 +00001611- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001612 Previously, the slight difference could cause compilation errors of the
1613 'zlib' module on systems with more than one version of zlib.
1614
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001615- The MSI compileall step was fixed to also support a TARGETDIR
1616 with spaces in it.
1617
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001618- Bug #1517388: sqlite3.dll is now installed on Windows independent
1619 of Tcl/Tk.
1620
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001621- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001622 trying to be installed even though it's empty.
Georg Brandlad29e632006-06-21 17:45:17 +00001623
Neal Norwitzb15ac312006-06-29 04:10:08 +00001624Tests
1625-----
1626
1627- Call os.waitpid() at the end of tests that spawn child processes in order
1628 to minimize resources (zombies).
1629
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001630Documentation
1631-------------
1632
Nick Coghlan2d792252006-07-06 13:47:18 +00001633- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1634 documentation for the warnings module.
1635
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001636- Patch #1509163: MS Toolkit Compiler no longer available.
1637
Neal Norwitz56640df2006-07-10 02:36:41 +00001638- Patch #1504046: Add documentation for xml.etree.

Nick Coghlanc649ec52006-05-29 12:43:05 +00001641What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +00001642================================
Anthony Baxter51bcb682006-04-05 14:51:42 +00001643
Anthony Baxterd1136802006-06-19 12:04:15 +00001644*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +00001645
1646Core and builtins
1647-----------------
1648
Georg Brandla56b9152006-06-19 06:35:54 +00001649- Patch #1507676: Error messages returned by invalid abstract object operations
1650 (such as iterating over an integer) have been improved and now include the
1651 type of the offending object to help with debugging.
1652
Brett Cannonea3912b2006-06-13 21:46:41 +00001653- Bug #992017: A classic class that defined a __coerce__() method that returned
1654 its arguments swapped would infinitely recurse and segfault the interpreter.
1655
Neal Norwitz909eb122006-06-12 02:13:21 +00001656- Fix the socket tests so they can be run concurrently.
1657
Neal Norwitzb9845e72006-06-12 02:11:18 +00001658- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001659 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001660
Brett Cannon22565aa2006-06-09 22:31:23 +00001661- Bug #532646: object.__call__() will continue looking for the __call__
1662 attribute on objects until one without one is found. This leads to recursion
1663 when you take a class and set its __call__ attribute to an instance of the
1664 class. Originally fixed for classic classes, but this fix is for new-style.
1665 Removes the infinite_rec_3 crasher.
1666
Georg Brandl24250812006-06-09 18:45:48 +00001667- The string and unicode methods startswith() and endswith() now accept
1668 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1669
Brett Cannonde3b0522006-06-08 17:00:45 +00001670- Buffer objects, at the C level, never used the char buffer
1671 implementation even when the char buffer for the wrapped object was
1672 explicitly requested (originally returned the read or write buffer).
1673 Now a TypeError is raised if the char buffer is not present but is
1674 requested.
1675
Georg Brandlddbaa662006-06-04 21:56:52 +00001676- Patch #1346214: Statements like "if 0: suite" are now again optimized
1677 away like they were in Python 2.4.
1678
Georg Brandlb7c8f542006-05-27 12:30:25 +00001679- Builtin exceptions are now full-blown new-style classes instead of
1680 instances pretending to be classes, which speeds up exception handling
1681 by about 80% in comparison to 2.5a2.
1682
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001683- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1684 Unicode 4.1.
1685
Georg Brandlf4ef1162006-05-26 18:03:31 +00001686- Patch #921466: sys.path_importer_cache is now used to cache valid and
1687 invalid file paths for the built-in import machinery which leads to
1688 fewer open calls on startup.
1689
Tim Peters696cf432006-05-24 21:10:40 +00001690- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1691 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1692 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1693 the number of input digits (it was and remains linear-time for bases
1694 2, 4, 8, 16 and 32).
1695
Tim Petersb713ec22006-05-23 18:45:30 +00001696- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1697 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1698 an integer close to ``sys.maxint``. This was repaired by patch
1699 #1335972, which also gives a nice speedup.
1700
Richard Jonescebbefc2006-05-23 18:28:17 +00001701- Patch #1337051: reduced size of frame objects.
1702
1703- PyErr_NewException now accepts a tuple of base classes as its
1704 "base" parameter.
1705
Richard Jones7c88dcc2006-05-23 10:37:38 +00001706- Patch #876206: function call speedup by retaining allocated frame
1707 objects.
1708
Georg Brandl7b90e162006-05-18 07:01:27 +00001709- Bug #1462152: file() now checks more thoroughly for invalid mode
1710 strings and removes a possible "U" before passing the mode to the
1711 C library function.
1712
Neal Norwitz1004a532006-05-15 07:17:23 +00001713- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1714
Neal Norwitz373f0a72006-05-15 07:04:36 +00001715- Bug #1487966: Fix SystemError with conditional expression in assignment
1716
Martin v. Löwis879768d2006-05-11 13:28:43 +00001717- WindowsError now has two error code attributes: errno, which carries
1718 the error values from errno.h, and winerror, which carries the error
1719 values from winerror.h. Previous versions put the winerror.h values
1720 (from GetLastError()) into the errno attribute.
1721
Martin v. Löwis77736712006-05-04 05:51:03 +00001722- Patch #1475845: Raise IndentationError for unexpected indent.
1723
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001724- Patch #1479181: split open() and file() from being aliases for each other.
1725
Tim Peters44bd9862006-06-01 13:49:23 +00001726- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1727 methods were always silently ignored by dictionaries when comparing keys.
1728 They are now passed through (except when using the C API function
1729 ``PyDict_GetItem()``, whose semantics did not change).
1730
1731- Bug #1456209: In some obscure cases it was possible for a class with a
1732 custom ``__eq__()`` method to confuse dict internals when class instances
1733 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1734 No, you don't have any code that did this ;-)

1737-----------------
1738
Trent Mick960a3f82006-06-28 20:30:41 +00001739- Bug #1295808: expat symbols should be namespaced in pyexpat
1740
1741- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1742
Brett Cannon6ee7d012006-06-08 16:23:04 +00001743- Change binascii.hexlify to accept a read-only buffer instead of only a char
1744 buffer and actually follow its documentation.
1745
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001746- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1747
Nick Coghlanc649ec52006-05-29 12:43:05 +00001748- Patch #1478788 (modified version): The functional extension module has
1749 been renamed to _functools and a functools Python wrapper module added.
1750 This provides a home for additional function related utilities that are
1751 not specifically about functional programming. See PEP 309.
1752
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001753- Patch #1493701: performance enhancements for struct module.
1754
Georg Brandl378d5922006-05-17 14:26:50 +00001755- Patch #1490224: time.altzone is now set correctly on Cygwin.
1756
Georg Brandl8d3342b2006-05-16 07:38:27 +00001757- Patch #1435422: zlib's compress and decompress objects now have a
1758 copy() method.
1759
Andrew MacIntyre92913322006-06-13 15:04:24 +00001760- Patch #1454481: thread stack size is now tunable at runtime for thread
1761 enabled builds on Windows and systems with Posix threads support.
1762
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001763- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1764 (up to the system limit of 32K characters).
1765
1766- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1767 As a result, these functions now raise WindowsError instead of OSError.
1768
Tim Peters7a822da2006-05-25 21:50:17 +00001769- ``time.clock()`` on Win64 should use the high-performance Windows
1770 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1771 Windows platforms).
1772
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001773- Calling Tk_Init twice is refused if the first call failed as that
1774 may deadlock.
1775
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001776- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1777 accept it without potentially using an uninitialized pointer.
1778
1779- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1780 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

1785
Gregory P. Smith372b5832006-06-05 18:48:21 +00001786- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1787 parameter is supplied. [SF pybsddb bug #1477863]
1788
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001789- bsddb: the __len__ method of a DB object has been fixed to return correct
1790 results. It could previously incorrectly return 0 in some cases.
1791 Fixes SF bug 1493322 (pybsddb bug 1184012).
1792
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001793- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1794 aborts the db transaction safely when a modifier callback fails.
1795 Fixes SF python patch/bug #1408584.
1796
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001797- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001798 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001799 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1800 database calls that would previously deadlock. [SF python bug #775414]

1831
Tim Peters43898b42006-06-14 04:09:25 +00001832- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1833 guarantee that adjacent triples in the return list always describe
1834 non-adjacent blocks. Previously, a pair of matching blocks could end
1835 up being described by multiple adjacent triples that formed a partition
1836 of the matching pair.

Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001846- The wsgiref package has been added to the standard library.
1847
Nick Coghlan676725d2006-06-08 13:54:49 +00001848- The functions update_wrapper() and wraps() have been added to the functools
1849 module. These make it easier to copy relevant metadata from the original
1850 function when writing wrapper functions.
1851
Tim Petersd6a9eef2006-06-05 01:48:21 +00001852- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1853 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001854
Martin v. Löwis3f767792006-06-04 19:36:28 +00001855- Patch #1359618: Speed up charmap encoder by using a trie structure
1856 for lookup.
1857
Tim Petersd609b1a2006-06-02 23:22:51 +00001858- The functions in the ``pprint`` module now sort dictionaries by key
1859 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1860 if and only if its display required more than one line, although that
1861 wasn't documented. The new behavior increases predictability; e.g.,
1862 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1863
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001864- Patch #1497027: try HTTP digest auth before basic auth in urllib2

1873
Georg Brandlb89316f2006-05-17 15:51:16 +00001874- Patch #1180296: Two new functions were added to the locale module:
1875 format_string() to get the effect of "format % items" but locale-aware,
1876 and currency() to format a monetary number with currency sign.

1885 stdout arguments, making it possible to redirect input and output
1886 for remote debugging.
1887
1888- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1889 a couple of issues, notably handling of long file names using the
1890 GNU LONGNAME extension.
1891
1892- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1893 new flag when ``name`` is already the name of an option flag.
1894
1895- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1896 package.

1940-----------------
1941
Thomas Heller1b046642006-04-18 18:51:06 +00001942- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1943 by converting these apis from macros into exported functions again:
1944
1945 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1946 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1947 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne

1950
Martin v. Löwis45294a92006-04-18 06:24:08 +00001951- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1952
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001953- All uses of PyStructSequence_InitType have been changed to initialize
1954 the type objects only once, even if the interpreter is initialized
1955 multiple times.
1956
Neal Norwitz61546162006-04-14 05:20:28 +00001957- Bug #1454485, array.array('u') could crash the interpreter. This was
1958 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1959 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1960
1961- Py_UNICODE is unsigned. It was always documented as unsigned, but
1962 due to a bug had a signed value in previous versions.
1963
Tim Peters3a5e8b12006-04-11 01:44:07 +00001964- Patch #837242: ``id()`` of any Python object always gives a positive
1965 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1966 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001967 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001968 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001969
Tim Peters3a5e8b12006-04-11 01:44:07 +00001970 def __hash__(self):
1971 return id(self) # WRONG
1972
1973 because a hash result must be a (short) Python int but it was always
1974 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001975 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001976 was always usable as a hash value before this patch. That's no longer
1977 necessarily so.
1978
1979- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001980 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001981 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001982 #1454844)
1983
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001984- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1985 involving generators that have paused outside of any ``try`` or ``with``
1986 blocks. (In 2.5a1, a paused generator that was part of a reference
1987 cycle could not be garbage collected, regardless of whether it was
1988 paused in a ``try`` or ``with`` block.)

2018 abusing errno.
2019
Tim Peters711bf302006-04-25 03:31:36 +00002020- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2021 a doctest to be skipped (the code is not run, and the expected output
2022 or exception is ignored).
2023
Nick Coghlanda2268f2006-04-24 04:37:15 +00002024- Fixed contextlib.nested to cope with exceptions being raised and
2025 caught inside exit handlers.
2026
Greg Wardab05edc2006-04-23 03:47:58 +00002027- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2028 hex, octal, or binary; add ``append_const`` action; keep going if
2029 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2030 added ``epilog`` for better help generation).
2031
Tim Peters21fbd572006-04-21 21:18:10 +00002032- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2033 called from a thread spawned as a side effect of importing a module.
2034
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002035- The pydoc module now supports documenting packages contained in
2036 .zip or .egg files.
2037
2038- The pkgutil module now has several new utility functions, such
2039 as ``walk_packages()`` to support working with packages that are either
2040 in the filesystem or zip files.
2041
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002042- The mailbox module can now modify and delete messages from
2043 mailboxes, in addition to simply reading them. Thanks to Gregory
2044 K. Johnson for writing the code, and to the 2005 Google Summer of
2045 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002046
Tim Petersc7605f22006-04-17 21:12:33 +00002047- The ``__del__`` method of class ``local`` in module ``_threading_local``
2048 returned before accomplishing any of its intended cleanup.
2049
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002050- Patch #790710: Add breakpoint command lists in pdb.

Martin v. Löwis4be4e652006-04-17 19:25:49 +00002076- The Makefile now has a reindent target, which runs reindent.py on
2077 the library.
2078
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002079- Patch #1470875: Building Python with MS Free Compiler
2080
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00002081- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002082
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002083- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2084 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002085 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002086 CXX from --with-cxx-main, see description in README.
2087
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002088- Patch #1429775: Link extension modules with the shared libpython.
2089
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002090- Fixed a libffi build problem on MIPS systems.
2091
Tim Peters8931ff12006-05-13 23:28:20 +00002092- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2093 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2094 and "%zu" for unsigned integers of type ``size_t``.
2095
Anthony Baxter51bcb682006-04-05 14:51:42 +00002096Tests
2097-----
2098
Nick Coghlanda2268f2006-04-24 04:37:15 +00002099- test_contextlib now checks contextlib.nested can cope with exceptions
2100 being raised and caught inside exit handlers.
2101
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002102- test_cmd_line now checks operation of the -m and -c command switches
2103
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002104- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2105 it separately and by hand. It also wasn't cleaning up its changes to
2106 the current Decimal context.
2107
Thomas Woutersabd08882006-04-26 15:53:30 +00002108- regrtest.py now has a -M option to run tests that test the new limits of
2109 containers, on 64-bit architectures. Running these tests is only sensible
2110 on 64-bit machines with more than two gigabytes of memory. The argument
2111 passed is the maximum amount of memory for the tests to use.
2112
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00002113Tools

Anthony Baxter51bcb682006-04-05 14:51:42 +00002119Documentation
2120-------------
2121
Tim Petersb06d28c2006-05-12 01:57:59 +00002122- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2123
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002124- PEP 343: Added Context Types section to the library reference
2125 and attempted to bring other PEP 343 related documentation into
2126 line with the implementation and/or python-dev discussions.
2127
Tim Peters8dc73d22006-04-24 02:03:16 +00002128- Bug #1337990: clarified that ``doctest`` does not support examples
2129 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002132What's New in Python 2.5 alpha 1?
2133=================================
2134
Anthony Baxterebed3f62006-04-03 15:03:44 +00002135*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002136
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002137Core and builtins
2138-----------------
2139
Nick Coghlan43832302006-04-23 17:04:07 +00002140- PEP 338: -m command line switch now delegates to runpy.run_module
2141 allowing it to support modules in packages and zipfiles
2142
Martin v. Löwisc661b882006-04-20 04:54:23 +00002143- On Windows, .DLL is not an accepted file name extension for
2144 extension modules anymore; extensions are only found if they
2145 end in .PYD.
2146
Martin v. Löwisea62d252006-04-03 10:56:49 +00002147- Bug #1421664: sys.stderr.encoding is now set to the same value as
2148 sys.stdout.encoding.
2149
Neal Norwitz92e212f2006-04-03 04:48:37 +00002150- __import__ accepts keyword arguments.
2151
Georg Brandlccadf842006-03-31 18:54:53 +00002152- Patch #1460496: round() now accepts keyword arguments.
2153
Anthony Baxter262c00a2006-03-30 10:53:17 +00002154- Fixed bug #1459029 - unicode reprs were double-escaped.
2155
Hye-Shik Changd478f342006-03-23 12:32:36 +00002156- Patch #1396919: The system scope threads are reenabled on FreeBSD
2157 5.4 and later versions.
2158
Neal Norwitze98ccf62006-03-23 05:39:47 +00002159- Bug #1115379: Compiling a Unicode string with an encoding declaration
2160 now gives a SyntaxError.
2161
Georg Brandlabd1ff82006-03-18 07:59:59 +00002162- Previously, Python code had no easy way to access the contents of a
2163 cell object. Now, a ``cell_contents`` attribute has been added
2164 (closes patch #1170323).
2165
Tim Peterscf79aac2006-03-16 01:14:46 +00002166- Patch #1123430: Python's small-object allocator now returns an arena to
2167 the system ``free()`` when all memory within an arena becomes unused
2168 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2169 freed. Some applications will see a drop in virtual memory size now,
2170 especially long-running applications that, from time to time, temporarily
2171 use a large number of small objects. Note that when Python returns an
2172 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002173 platform C library will in turn return that memory to the operating system.
2174 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002175 appears to be effective at least on Microsoft C and gcc-based systems.
2176 Thanks to Evan Jones for hard work and patience.
2177
Georg Brandl533ff6f2006-03-08 18:09:27 +00002178- Patch #1434038: property() now uses the getter's docstring if there is
2179 no "doc" argument given. This makes it possible to legitimately use
2180 property() as a decorator to produce a read-only property.
2181
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002182- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2183 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2184 of requiring an int or long in slicing and a few other contexts, enabling
2185 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2186
Neal Norwitz995acdf2006-03-07 05:01:00 +00002187- Fixed various bugs reported by Coverity's Prevent tool.
2188
Brett Cannonbf364092006-03-01 04:25:17 +00002189- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2190 new exception base class, BaseException, which has a new message attribute.
2191 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2192 Raising a string exception now raises a DeprecationWarning.
2193
Thomas Woutersfb609f42006-02-28 16:37:25 +00002194- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2195 explicitly relative, using 'from .module import name' to mean 'from the same
2196 package as this module is in. Imports without dots still default to the
2197 old relative-then-absolute, unless 'from __future__ import
2198 absolute_import' is used.
2199
Brett Cannona7446e32006-02-27 23:39:10 +00002200- Properly check if 'warnings' raises an exception (usually when a filter set
2201 to "error" is triggered) when raising a warning for raising string
2202 exceptions.
2203
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002204- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002205 The name was removed from Include/code.h.
2206
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002207- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002208
Guido van Rossum1968ad32006-02-25 22:38:04 +00002209- Patch 1433928:
2210 - The copy module now "copies" function objects (as atomic objects).
2211 - dict.__getitem__ now looks for a __missing__ hook before raising
2212 KeyError.
2213
Tim Peters84ef21c2006-02-28 20:39:06 +00002214- PEP 343: with statement implemented. Needs ``from __future__ import
2215 with_statement``. Use of 'with' as a variable will generate a warning.
2216 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002217 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002218 The following objects have __context__ methods:
2219 - The built-in file type.
2220 - The thread.LockType type.
2221 - The following types defined by the threading module:
2222 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2223 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002224
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002225- Fix the encodings package codec search function to only search
2226 inside its own package. Fixes problem reported in patch #1433198.
2227
2228 Note: Codec packages should implement and register their own
2229 codec search function. PEP 100 has the details.
2230
Tim Peters9ea89d22006-06-04 03:26:02 +00002231- PEP 353: Using ``Py_ssize_t`` as the index type.
2232
2233- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2234 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2235 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2236 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2237 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002238
Neal Norwitzfc76d632006-01-10 06:03:13 +00002239- Patch #1400181, fix unicode string formatting to not use the locale.
2240 This is how string objects work. u'%f' could use , instead of .
2241 for the decimal point. Now both strings and unicode always use periods.
2242
Neal Norwitz671b9e32006-01-09 07:07:12 +00002243- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2244 configure would break checking curses.h.
2245
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002246- Bug #959576: The pwd module is now builtin. This allows Python to be
2247 built on UNIX platforms without $HOME set.
2248
Neal Norwitzc10978f2005-12-19 06:07:16 +00002249- Bug #1072182, fix some potential problems if characters are signed.
2250
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002251- Bug #889500, fix line number on SyntaxWarning for global declarations.
2252
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002253- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2254
Neal Norwitze7214a12005-12-18 05:03:17 +00002255- Support for converting hex strings to floats no longer works.
2256 This was not portable. float('0x3') now raises a ValueError.
2257
Barry Warsaw2a38a862005-12-18 01:27:35 +00002258- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002259 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002260 is now displayed in interactive prompt banner.
2261
Georg Brandlfa166682005-12-17 21:45:17 +00002262- Implementation of PEP 341 - Unification of try/except and try/finally.
2263 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002264 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002265
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002266- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2267 now encodes backslash correctly.
2268
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002269- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2270
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002271- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002272 and long longs.
2273
Neal Norwitz67715f02005-11-09 06:59:35 +00002274- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002275 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002276 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002277
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002278- Replaced most Unicode charmap codecs with new ones using the
2279 new Unicode translate string feature in the builtin charmap
2280 codec; the codecs were created from the mapping tables available
2281 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2282 encodings now include a mapping for the Apple logo)
2283
Tim Peterse3547fd2005-12-16 23:13:57 +00002284- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002285
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002286- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002287
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002288- A new AST parser implementation was completed. The abstract
2289 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002290 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002291
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002292- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002293 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2294
Neal Norwitz708e51a2005-10-03 04:48:15 +00002295- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2296
Neal Norwitz11bd1192005-10-03 00:54:56 +00002297- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2298 Provide a warning when a directory is passed on the command line.
2299
Neal Norwitz40d37812005-10-02 01:48:49 +00002300- Fix segfault with invalid coding.
2301
2302- SF bug #772896: unknown encoding results in MemoryError.
2303
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002304- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002305 supported a __len__() method which evaluated to False when the iterator
2306 was empty.
2307
Guido van Rossum630db602005-09-20 18:49:54 +00002308- On 64-bit platforms, when __len__() returns a value that cannot be
2309 represented as a C int, raise OverflowError.
2310
Skip Montanarof8948ca2005-09-19 03:54:46 +00002311- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002312 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002313
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002314- SF bug #893549: parsing keyword arguments was broken with a few format
2315 codes.
2316
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002317- Changes donated by Elemental Security to make it work on AIX 5.3
2318 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2319 bug #105470: test_pwd fails on 64bit system (Opteron).
2320
Guido van Rossum539c6622005-09-14 17:49:54 +00002321- Changes donated by Elemental Security to make it work on HP-UX 11 on
2322 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2323
Georg Brandl4550b8d2005-08-26 06:43:52 +00002324- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002325 (fixes bug #1119418).
2326
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002327- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2328
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002329- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2330 exceptions that cause a function to exit.
2331
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002332- The implementation of set() and frozenset() was revised to use its
2333 own internal data structure. Memory consumption is reduced by 1/3
2334 and there are modest speed-ups as well. The API is unchanged.
2335
Tim Petersde7990b2005-07-17 23:45:23 +00002336- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2337
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002338- SF bug #1229429: PyObject_CallMethod failed to decrement some
2339 reference counts in some error exit cases.
2340
Tim Petersecc6e6a2005-07-10 22:30:55 +00002341- SF bug #1185883: Python's small-object memory allocator took over
2342 a block managed by the platform C library whenever a realloc specified
2343 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002344 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002345 portable way to copy data from the C-managed block into Python's
2346 small-object space without risking a memory fault. Python's small-object
2347 realloc now leaves such blocks under the control of the platform C
2348 realloc.

Michael W. Hudsonb8963812005-07-05 15:21:58 +00002350- SF bug #1232517: An overflow error was not detected properly when
2351 attempting to convert a large float to an int in os.utime().
2352
Raymond Hettinger3296e692005-06-29 23:29:56 +00002353- SF bug #1224347: hex longs now print with lowercase letters just
2354 like their int counterparts.
2355
Michael W. Hudson188d4362005-06-20 16:52:57 +00002356- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2357 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2358 interpreter states; back out that fix and do a better job (see
2359 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2360 for a longer write-up of the problem).
2361
Michael W. Hudsondf888462005-06-03 14:41:55 +00002362- SF patch #1180995: marshal now uses a binary format by default when
2363 serializing floats.
2364
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002365- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2366 the routines that promise to produce IEEE 754 binary representations
2367 of floats now simply copy bytes around.
2368
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002369- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2370 278.
2371
Brett Cannonc3647ac2005-04-26 03:45:26 +00002372- patch #1109424: int, long, float, complex, and unicode now check for the
2373 proper magic slot for type conversions when subclassed. Previously the
2374 magic slot was ignored during conversion. Semantics now match the way
2375 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002376 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002377 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002378 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002379
Barry Warsawc8d907c2005-04-19 23:43:40 +00002380- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2381 NULL, now raise an AttributeError when attempting to set or delete the
2382 attribute. Previously a TypeError was raised, but this was inconsistent
2383 with the equivalent pure-Python implementation.
2384
Michael W. Hudson774479c2005-04-18 08:46:17 +00002385- It is now safe to call PyGILState_Release() before
2386 PyEval_InitThreads() (note that if there is reason to believe there
2387 are multiple threads around you still must call PyEval_InitThreads()
2388 before using the Python API; this fix is for extension modules that
2389 have no way of knowing if Python is multi-threaded yet).
2390
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002391- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2392 disabled caused a crash.
2393
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002394- Bug #1165306: instancemethod_new allowed the creation of a method
2395 with im_class == im_self == NULL, which caused a crash when called.
2396
Tim Petersecc6e6a2005-07-10 22:30:55 +00002397- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002398 fixes the crash seen in bug #1165761
2399
Raymond Hettinger96229b12005-03-11 06:49:40 +00002400- Added two new builtins, any() and all().
2401
Brett Cannon409d8f22005-03-05 06:47:57 +00002402- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002403 (e.g., ``class C(): pass`` is no longer a syntax error).
2404 Patch #1176012 added support to the 'parser' module and 'compiler' package
2405 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002406
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002407- Patch #1115086: Support PY_LONGLONG in structmember.
2408
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002409- Bug #1155938: new style classes did not check that __init__() was
2410 returning None.
2411
Tim Petersecc6e6a2005-07-10 22:30:55 +00002412- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002413 ('\') with a specific error message.
2414
Martin v. Löwisff232d72005-03-03 09:24:38 +00002415- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2416
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002417- Bug #1124295: the __name__ attribute of file objects was
2418 inadvertently made inaccessible in restricted mode.
2419
Tim Petersecc6e6a2005-07-10 22:30:55 +00002420- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002421 an ferror() call.
2422
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002423- min() and max() now support key= arguments with the same meaning as in
2424 list.sort().
2425
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002426- The peephole optimizer now performs simple constant folding in expressions:
2427 (2+3) --> (5).
2428
Raymond Hettingera422c342005-01-11 03:03:27 +00002429- set and frozenset objects can now be marshalled. SF #1098985.
2430
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002431- Bug #1077106: Poor argument checking could cause memory corruption
2432 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002433
Jeremy Hyltonab630502005-02-04 18:44:06 +00002434- The parser did not complain about future statements in illegal
2435 positions. It once again reports a syntax error if a future
2436 statement occurs after anything other than a doc string.
2437
Neil Schemenauercf52c072005-08-12 17:34:58 +00002438- Change the %s format specifier for str objects so that it returns a
2439 unicode instance if the argument is not an instance of basestring and
2440 calling __str__ on the argument returns a unicode instance.
2441
Tim Petersf4e69282006-02-27 17:15:31 +00002442- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2443 current thread state when the auto-GIL-state machinery knows about
2444 it (since the thread state is being deleted, continuing to remember it
2445 can't help, but can hurt if another thread happens to get created with
2446 the same thread id).
2447
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002448Extension Modules

2465
2466- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2467
2468- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002469 is deprecated. The undocumented re.engine variable no longer exists.

2473
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002474- The unicodedata module was updated to the 4.1 version of the Unicode
2475 database. The 3.2 version is still available as unicodedata.db_3_2_0
2476 for applications that require this specific version (such as IDNA).
2477
Neal Norwitzb62c4332006-03-04 18:35:47 +00002478- The timing module is no longer built by default. It was deprecated

2499
Martin v. Löwis14694662006-02-03 12:54:16 +00002500- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2501 are reported, the limit on path name lengths is removed, and stat reports
2502 WindowsError now (instead of OSError).
2503

2579 the request code argument, which results in more C-like behaviour
2580 for large or negative values.
2581
Tim Petersecc6e6a2005-07-10 22:30:55 +00002582- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

2621
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002622- the cPickle module no longer accepts the deprecated None option in the
2623 args tuple returned by __reduce__().
2624
Raymond Hettingerb2594052004-12-05 09:25:51 +00002625- itertools.islice() now accepts None for the start and step arguments.
2626 This allows islice() to work more readily with slices:

Tim Peters112aad32006-07-19 00:03:19 +00002637
Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002638- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2639 been renamed to have only a single underscore prefix. This was done to
2640 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002641
Nick Coghlan43832302006-04-23 17:04:07 +00002642- PEP 338: new module runpy defines a run_module function to support
2643 executing modules which provide access to source code or a code object
2644 via the PEP 302 import mechanisms.
2645
Anthony Baxter93f5b932006-04-03 08:05:07 +00002646- The email module's parsedate_tz function now sets the daylight savings
2647 flag to -1 (unknown) since it can't tell from the date whether it should

2654 in attribute values.
2655
Anthony Baxterc51ee692006-04-01 00:57:31 +00002656- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002657 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002658 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002659 module will not be built.
2660
Tim Petersc17976e2006-04-01 00:26:53 +00002661- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2662 aren't officially supported here, and trying to use them will probably
2663 raise an exception some day. But dicts have been allowed, and "mostly
2664 worked", so support for them won't go away without warning.
2665
Georg Brandl338ef7d2006-03-31 18:42:16 +00002666- Bug #1445068: getpass.getpass() can now be given an explicit stream
2667 argument to specify where to write the prompt.
2668
Georg Brandl22ec80b2006-03-31 18:25:44 +00002669- Patch #1462313, bug #1443328: the pickle modules now can handle classes
2670 that have __private names in their __slots__.
2671

2678 to make it easier to monitor when daemon threads have completed
2679 processing all enqueued tasks. Patch #1455676.
2680
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002681- popen2.Popen objects now preserve the command in a .cmd attribute.
2682
Thomas Hellerc61c0492006-03-22 10:09:27 +00002683- Added the ctypes ffi package.
2684
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002685- email 4.0 package now integrated. This is largely the same as the email 3.0
2686 package that was included in Python 2.3, except that PEP 8 module names are
2687 now used (e.g. mail.message instead of email.Message). The MIME classes
2688 have been moved to a subpackage (e.g. email.mime.text instead of
2689 email.MIMEText). The old names are still supported for now. Several
2690 deprecated Message methods have been removed and lots of bugs have been
2691 fixed. More details can be found in the email package documentation.
2692
Walter Dörwald40108c92006-03-27 08:15:44 +00002693- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2694 (a subclass of tuple) that provides incremental decoders and encoders
2695 (a way to use stateful codecs without the stream API). Python functions
2696 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2697 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2698 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002699
Walter Dörwald067db482006-03-15 22:17:27 +00002700- Patch #1359365: Calling next() on a closed StringIO.String object raises
2701 a ValueError instead of a StopIteration now (like file and cString.String do).
2702 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2703 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002704
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002705- A regrtest option -w was added to re-run failed tests in verbose mode.

Martin v. Löwis3e865952006-01-24 15:51:21 +00002753 specifications, raises IOErrors when proxies for unsupported protocols
2754 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00002777 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2778 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2779 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2780 Ronald L. Rivest offered this advice for Python:
2781
2782 "The consensus of researchers in this area (at least as
2783 expressed at the NIST Hash Function Workshop 10/31/05),
2784 is that SHA-256 is a good choice for the time being, but
2785 that research should continue, and other alternatives may
2786 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002787
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002788- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandl5284b532005-06-26 22:54:58 +00002872
Georg Brandl2f210b62005-06-26 22:09:06 +00002873- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
2874
Georg Brandlfbff1bc2005-06-26 21:36:25 +00002875- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
2876 error messages.
2877
Georg Brandl379f99d2005-06-26 21:09:38 +00002878- Bug #1108948: Cookie.py produced invalid JavaScript code.
2879
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00002880- The tokenize module now detects and reports indentation errors.
2881 Bug #1224621.
2882
Raymond Hettinger68c04532005-06-10 11:05:19 +00002883- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002884 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002885 the generate_tokens() function now accepts a callable argument that
2886 terminates by raising StopIteration.
2887
Georg Brandl9166e1a2005-06-04 09:20:03 +00002888- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2889
Georg Brandl268e61c2005-06-03 14:28:50 +00002890- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2891 component of the path.
2892
Skip Montanaro174dd222005-05-14 20:54:16 +00002893- Patch #1120353: The xmlrpclib module provides better, more transparent,
2894 support for datetime.{datetime,date,time} objects. With use_datetime set
2895 to True, applications shouldn't have to fiddle with the DateTime wrapper
2896 class at all.
2897
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002898- distutils.commands.upload was added to support uploading distribution
2899 files to PyPI.
2900
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002901- distutils.commands.register now encodes the data as UTF-8 before posting
2902 them to PyPI.
2903
Raymond Hettinger267b8682005-03-27 10:47:39 +00002904- decimal operator and comparison methods now return NotImplemented
2905 instead of raising a TypeError when interacting with other types. This
2906 allows other classes to implement __radd__ style methods and have them
2907 work as expected.
2908
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002909- Bug #1163325: Decimal infinities failed to hash. Attempting to
2910 hash a NaN raised an InvalidOperation instead of a TypeError.
2911
Tim Petersecc6e6a2005-07-10 22:30:55 +00002912- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002913 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2914

2918 to build.
2919
Martin v. Löwis637431b2005-03-03 23:12:42 +00002920- Patch #1103407: Properly deal with tarfile iterators when untarring
2921 symbolic links on Windows.

2944
Raymond Hettingerbab41432005-02-05 01:31:19 +00002945- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2946
Guido van Rossumd0641422005-02-03 15:01:24 +00002947- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2948 disables recursive traversal through instance attributes, which can
2949 be exploited in various ways.
2950
Tim Peterse3547fd2005-12-16 23:13:57 +00002951- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002952 flags on the HTTP listening socket.
2953
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002954- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2955 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2956
Fred Drakefbdeaad2006-07-29 16:56:15 +00002957- Patches #893642, #1039083: add allow_none, encoding arguments to
2958 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002959
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002960- Bug #1110478: Revert os.environ.update to do putenv again.
2961
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002962- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2963
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002964- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2965
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002966- Enhancements to the csv module:
2967
2968 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002969 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002970 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002971 + Dialect parameter parsing has been re-implemented to improve error
2972 reporting.
2973 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2974 dictates.
2975 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002976 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002977 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002978 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2979 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002980 + reader now allows \r characters to be quoted (previously it only allowed
2981 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002982 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002983 + Dialect classes passed to the module are no longer instantiated by
2984 the module before being parsed (the former validation scheme required
2985 this, but the mechanism was unreliable).
2986 + The dialect registry now contains instances of the internal
2987 C-coded dialect type, rather than references to python objects.
2988 + the internal c-coded dialect type is now immutable.
2989 + register_dialect now accepts the same keyword dialect specifications
2990 as the reader and writer, allowing the user to register dialects
2991 without first creating a dialect class.
2992 + a configurable limit to the size of parsed fields has been added -
2993 previously, an unmatched quote character could result in the entire
2994 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002995 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002996 the parser field size limit (returning the former limit). The initial
2997 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002998 + A line_num attribute has been added to the reader object, which tracks
2999 the number of lines read from the source iterator. This is not
3000 the same as the number of records returned, as records can span
3001 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003002 + reader and writer objects were not being registered with the cyclic-GC.
3003 This has been fixed.
3004
Brett Cannone6539c42005-01-08 02:43:53 +00003005- _DummyThread objects in the threading module now delete self.__block that is
3006 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3007 lock primitives tend to be limited in number and thus should not be wasted on
3008 a _DummyThread object. Fixes bug #1089632.
3009
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003010- The imghdr module now detects Exif files.
3011
Raymond Hettinger6065d322004-12-20 23:51:53 +00003012- StringIO.truncate() now correctly adjusts the size attribute.
3013 (Bug #951915).
3014
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003015- locale.py now uses an updated locale alias table (built using
3016 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3017 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003018 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003019
Raymond Hettinger3557f422004-12-07 12:02:02 +00003020- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3021
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003022- the pickle module no longer accepts the deprecated None option in the
3023 args tuple returned by __reduce__().
3024
Brett Cannon84667c02004-12-07 03:25:18 +00003025- optparse now optionally imports gettext. This allows its use in setup.py.
3026
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003027- the pickle module no longer uses the deprecated bin parameter.
3028
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003029- the shelve module no longer uses the deprecated binary parameter.
3030
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003031- the pstats module no longer uses the deprecated ignore() method.
3032
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003033- the filecmp module no longer uses the deprecated use_statcache argument.
3034
Raymond Hettinger664347b2004-12-04 21:21:53 +00003035- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3036 extended or overridden by subclasses. Formerly, the subclassed method would
3037 be ignored by the rest of the module. (Bug #1078905).
3038
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003039- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003040 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003041
Walter Dörwald36733692004-12-22 12:50:50 +00003042- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3043 once when a size argument is given. This prevents a buffer overflow in the
3044 tokenizer with very long source lines.
3045
Barry Warsaw538561e2006-01-01 21:48:54 +00003046- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3047 immediately after creating the object, without any intervening
3048 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003049
Skip Montanaro05885812005-01-16 20:48:27 +00003050- The reconvert.quote function can now emit triple-quoted strings. The
3051 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003052
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003053- ``UserString.MutableString`` now supports negative indices in
3054 ``__setitem__`` and ``__delitem__``
3055
Greg Ward40407942005-03-05 02:53:17 +00003056- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3057 correctly.
3058
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003059- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3060 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3061 character even if the user has passed a size parameter to get a proper
3062 line ending. Remove the special handling of a "\r\n" that has been split
3063 between two lines.
3064
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003065- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3066 about illegal code points. The codec now supports PEP 293 style error
3067 handlers.
3068
Walter Dörwald78a78b02005-09-01 12:04:29 +00003069- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003070 from the input stream, so that the output is a byte string in the correct
3071 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003072
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003073- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3074 considering it exactly like a '*'.
3075
Walter Dörwald007f8df2005-10-09 19:42:27 +00003076- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3077 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003078
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003079- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3080
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003081- Patch #1413711: Certain patterns of differences were making difflib
3082 touch the recursion limit.
3083
Walter Dörwald58917a62006-03-31 15:26:22 +00003084- Bug #947906: An object oriented interface has been added to the calendar
3085 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003086 called as a script (e.g. via ``python -mcalendar``). Localized month and
3087 weekday names can be ouput (even if an exotic encoding is used) using
3088 special classes that use unicode.

3105 The zlib module is now builtin on Windows.
3106
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003107- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3108
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003109- Bug #1189330: configure did not correctly determine the necessary
3110 value of LINKCC if python was built with GCC 4.0.
3111
Trent Mick8321b422005-07-26 02:29:21 +00003112- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3113 vulnerability in zlib 1.2.1 and 1.2.2.
3114
Brett Cannon08cd5982005-04-24 22:26:38 +00003115- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3116 flags that change binary compatibility. Changes were also made to
3117 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003118 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003119
Bob Ippolitoed233462005-03-29 13:47:59 +00003120- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3121 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3122 no longer exists). This configure patch makes things right.
3123
Martin v. Löwise2713be2005-03-08 15:03:08 +00003124- Bug #1158607: Build with --disable-unicode again.
3125
Brett Cannon46d96232005-02-16 00:07:19 +00003126- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3127 defined. Discovered as a result of not being able to build on OS X.
3128
Brett Cannon516592f2004-12-07 00:42:59 +00003129- setup.py now uses the directories specified in LDFLAGS using the -L option
3130 and in CPPFLAGS using the -I option for adding library and include
3131 directories, respectively, for compiling extension modules against. This has
3132 led to the core being compiled using the values in CPPFLAGS. It also removes
3133 the need for the special-casing of both DarwinPorts and Fink for darwin since
3134 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3135 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3136 Fink, ``-I/opt/local/include`` for DarwinPorts).

Brett Cannon43802422005-02-10 20:48:03 +00003138- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3139 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3140 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3141 Closes bug #1096244. Thanks Gregory Bond.

3145
Tim Petersc9d78aa2006-03-26 23:27:58 +00003146- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3147 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3148 is obtained via the ``PyObject_`` family, it must be released via the
3149 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3150 always been officially true, but when Python's small-object allocator was
3151 introduced, an attempt was made to cater to a few extension modules
3152 discovered at the time that obtained memory via ``PyObject_New`` but
3153 released it via ``PyMem_DEL``. It's years later, and if such code still
3154 exists it will fail now (probably with segfaults, but calling wrong
3155 low-level memory management functions can yield many symptoms).
3156
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003157- Added a C API for set and frozenset objects.

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003161- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3162 mapping argument now. This string is used as a mapping table. Byte values
3163 greater than the length of the string and 0xFFFE are treated as undefined
3164 mappings.
