12Core and builtins
13-----------------
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.

49 reference to themselves.
50
Amaury Forgeot d'Arc8d904c32008-04-22 21:17:18 +000051- Issue #2670: Fix a failure in urllib2.build_opener(), when passed two
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
Mark Dickinson26c25d92008-03-25 14:35:25 +000063- Issue #2478: fix failure of decimal.Decimal(0).sqrt()

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
69 platforms.

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.
78
Andrew M. Kuchling664553a2008-02-23 19:30:59 +000079- Bug #1389051, 1092502: fix excessively large memory allocations when
80 calling .read() on a socket object wrapped with makefile().

138
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000139- Issue #1920: "while 0" statements were completely removed by the compiler,
140 even in the presence of an "else" clause, which is supposed to be run when
141 the condition is false. Now the compiler correctly emits bytecode for the
142 "else" suite.
143

958-----------------
959
Neal Norwitz0bcafac2006-09-11 08:51:17 +0000960- Make _PyGILState_NoteThreadState() static, it was not used anywhere
961 outside of pystate.c and should not be necessary.
962
Brett Cannon19d76c52006-09-09 07:18:44 +0000963- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
964 allows calling unicode() on exceptions classes directly to succeed.
965
Georg Brandlecab6232006-09-06 06:47:02 +0000966- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
967 Also make sure that every exception class has __module__ set to
968 'exceptions'.
969
Georg Brandl37a9e572006-09-06 06:09:34 +0000970- Bug #1550983: emit better error messages for erroneous relative

980
Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000981- The return tuple from str.rpartition(sep) is (tail, sep, head) where
982 head is the original string if sep was not found.
983
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000984- Bug #1520864: unpacking singleton tuples in list comprehensions and
985 generator expressions (x for x, in ... ) works again. Fixing this problem
986 required changing the .pyc magic number. This means that .pyc files
987 generated before 2.5c2 will be regenerated.

1101
Neal Norwitz24b6f202006-09-05 04:43:56 +00001102- Fix infinite recursion when subclassing long and overriding __hash__.
1103
1104- Fix concatenation (+=) of long strings.
1105
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001106- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001107 compared equal or unequal to a string and a UnicodeDecodeError
1108 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001109
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001110 Instead, the equal (==) and unequal (!=) comparison operators will
1111 now issue a UnicodeWarning and interpret the two objects as
1112 unequal. The UnicodeWarning can be filtered as desired using
1113 the warning framework, e.g. silenced completely, turned into an
1114 exception, logged, etc.
1115
1116 Note that compare operators other than equal and unequal will still
1117 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001118
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001119- Fix segfault when doing string formatting on subclasses of long.
1120
1121- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1122 with new-style classes.
1123
1124- Fix bug related to __len__ functions returning negative values with
1125 classic classes.
1126
1127- Patch #1538606, Fix __index__() clipping. There were some problems
1128 discovered with the API and how integers that didn't fit into Py_ssize_t
1129 were handled. This patch attempts to provide enough alternatives
1130 to effectively use __index__.
1131
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001132- Bug #1536021: __hash__ may now return long int; the final hash
1133 value is obtained by invoking hash on the long int.
1134
Thomas Hellerab1049c2006-08-08 17:37:00 +00001135- Bug #1536786: buffer comparison could emit a RuntimeWarning.

1138 sys.stdin is closed.
1139
Thomas Heller74d36f02006-08-04 18:17:40 +00001140- On Windows, the PyErr_Warn function is now exported from
1141 the Python dll again.
1142
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001143- Bug #1191458: tracing over for loops now produces a line event
1144 on each iteration. Fixing this problem required changing the .pyc
1145 magic number. This means that .pyc files generated before 2.5c1
1146 will be regenerated.
1147
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001148- Bug #1333982: string/number constants were inappropriately stored
1149 in the byte code and co_consts even if they were not used, ie
1150 immediately popped off the stack.
1151
Georg Brandle9462c72006-08-04 18:03:37 +00001152- Fixed a reference-counting problem in property().

1156-------
1157
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001158- Fix a bug in the ``compiler`` package that caused invalid code to be
1159 generated for generator expressions.
1160
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001161- The distutils version has been changed to 2.5.0. The change to
1162 keep it programmatically in sync with the Python version running
1163 the code (introduced in 2.5b3) has been reverted. It will continue
1164 to be maintained manually as static string literal.
1165
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001166- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001167 and this cannot be converted to the required C type, an exception is
1168 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001169 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001170
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001171- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001172 an exception.
1173
Tim Peterscbdd3502006-09-05 01:47:53 +00001174- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001175 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001176 workarounds for clocks with low resolution, to stop the code yielding
1177 duplicate UUIDs.
1178
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001179- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1180 before raising SystemExit, allowing IDLE to honor quit() and exit().
1181
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001182- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1183
Georg Brandl7a1af772006-08-14 21:55:28 +00001184- Patch #1536071: trace.py should now find the full module name of a

1193 str(exception) raised an exception.
1194
Neil Schemenauer06ded092006-08-04 16:20:30 +00001195- Fix a bug in the ``compiler`` package that caused invalid code to be
1196 generated for nested functions.

Thomas Heller1ce433e2006-08-14 16:20:04 +00001209- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1210 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1211
Thomas Heller86720042006-08-14 11:17:48 +00001212- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1213 uses the _as_parameter_ attribute when objects are passed to foreign
1214 function calls. The ctypes version number was changed to 1.0.1.
1215
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001216- Bug #1530559, struct.pack raises TypeError where it used to convert.
1217 Passing float arguments to struct.pack when integers are expected
1218 now triggers a DeprecationWarning.

1253-----
1254
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001255- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1256
Tim Peters4643c2f2006-08-10 22:45:34 +00001257- Bug #1069160. Internal correctness changes were made to
1258 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1259 the documentation was changed to state that the return value
1260 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001263What's New in Python 2.5 beta 3?
1264================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001265
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001266*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001267
1268Core and builtins
1269-----------------
1270
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001271- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001272 returned a long (see PEP 353).
1273
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001274- Bug #1515471: string.replace() accepts character buffers again.
1275
Neal Norwitz07aadb12006-07-30 06:55:48 +00001276- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1277 This provides the proper warning for struct.pack().
1278 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1279
Neal Norwitz0d62a062006-07-30 06:53:31 +00001280- Patch #1531113: Fix augmented assignment with yield expressions.
1281 Also fix a SystemError when trying to assign to yield expressions.
1282
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001283- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1284 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1285 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1286 excessive filesystem operations during imports.
1287
Tim Petersbc24eee2006-07-27 01:14:53 +00001288- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1289 operations on signed longs that are formally undefined by C.
1290 Unfortunately, at least one compiler now cares about that, so complicated
1291 the code to make that compiler happy again.
1292
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001293- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1294
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001295- Patch #1232023: Stop including current directory in search
1296 path on Windows.
1297
Neal Norwitze1fdb322006-07-21 05:32:28 +00001298- Fix some potential crashes found with failmalloc.
1299
Neal Norwitze7563102006-07-17 01:00:16 +00001300- Fix warnings reported by Klocwork's static analysis tool.
1301
Neal Norwitz84be93b2006-07-16 01:50:38 +00001302- Bug #1512814, Fix incorrect lineno's when code within a function
1303 had more than 255 blank lines.
1304
Georg Brandl9dceedb2006-07-12 15:31:17 +00001305- Patch #1521179: Python now accepts the standard options ``--help`` and
1306 ``--version`` as well as ``/?`` on Windows.
1307
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001308- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001309 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001310 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001311
Tim Peters112aad32006-07-19 00:03:19 +00001312- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001313 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001314 new ``sys._current_frames()`` returns a dictionary with one entry,
1315 mapping the faux "thread id" 0 to the current frame.
1316
Ronald Oussoren3075e162006-07-25 20:28:55 +00001317- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001318
Ronald Oussoren3075e162006-07-25 20:28:55 +00001319
Neal Norwitza1f10902006-07-12 07:28:29 +00001320Library
1321-------
1322
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001323- Correction of patch #1455898: In the mbcs decoder, set final=False
1324 for stream decoder, but final=True for the decode function.
1325
Georg Brandl07fec3a2006-08-01 18:49:24 +00001326- os.urandom no longer masks unrelated exceptions like SystemExit or
1327 KeyboardInterrupt.
1328
Tim Peters4643c2f2006-08-10 22:45:34 +00001329- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001330 shutil.copytree on Windows
1331
Georg Brandle34ac7c2006-07-30 11:07:23 +00001332- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1333 refers to file descriptors, not file objects.
1334
Tim Peterscbdd3502006-09-05 01:47:53 +00001335- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001336 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001337 #1513611, and probably others.
1338
Georg Brandledd9b0d2006-07-29 09:33:26 +00001339- Bug #1441397: The compiler module now recognizes module and function
1340 docstrings correctly as it did in Python 2.4.
1341
Tim Peters6f681472006-07-27 23:44:37 +00001342- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1343 lost that tests are sorted by name before being run. This rarely
1344 matters for well-written tests, but can create baffling symptoms if
1345 side effects from one test to the next affect outcomes. ``DocTestFinder``
1346 has been changed to sort the list of tests it returns.
1347
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001348- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001349 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001350
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001351- Bug #978833: Really close underlying socket in _socketobject.close.
1352
Georg Brandldb232dc2006-08-20 13:15:43 +00001353- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1354 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001355
Georg Brandlcf0c1722006-07-26 07:23:32 +00001356- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1357 to recursive calls and call it with the failing package name.
1358
Martin v. Löwis0b483032006-07-25 09:53:12 +00001359- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1360
Georg Brandlc13c34c2006-07-24 14:09:56 +00001361- Patch #1515343: Fix printing of deprecated string exceptions with a
1362 value in the traceback module.
1363
Greg Ward48fae7a2006-07-23 16:05:51 +00001364- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1365
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001366- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1367
Brett Cannoncaebe222006-07-18 04:41:36 +00001368- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1369 argument tuple. For arguments where zero is illegal, the value is forced to
1370 the minimum value that is correct. This is to support an undocumented but
1371 common way people used to fill in inconsequential information in the time
1372 tuple pre-2.4.
1373
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001374- Patch #1220874: Update the binhex module for Mach-O.
1375
Barry Warsawb110bad2006-07-21 14:51:07 +00001376- The email package has improved RFC 2231 support, specifically for
1377 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1378 (name*0=<blah>) parameter continuations. This may change the types of
1379 values returned from email.message.Message.get_param() and friends.
1380 Specifically in some cases where non-encoded continuations were used,
1381 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1382 will just return the string (since non-encoded continuations don't have
1383 charset and language parts).
1384
1385 Also, whereas % values were decoded in all parameter continuations, they are
1386 now only decoded in encoded parameter parts.
1387
Ronald Oussoren3075e162006-07-25 20:28:55 +00001388- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1389
1390- Bug #1517996: IDLE now longer shows the default Tk menu when a
1391 path browser, class browser or debugger is the frontmost window on MacOS X
1392
Barry Warsaw00decd72006-07-27 23:43:15 +00001393- Patch #1520294: Support for getset and member descriptors in types.py,
1394 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1395 of an object against these built-in types and more importantly, for getting
1396 their docstrings printed in the interactive interpreter's help() function.

1401
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001402- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1403 a socket operation on a socket with a timeout, the exception will be
1404 caught correctly. Previously, the exception was not caught.
1405
Thomas Heller1393d6a2006-07-28 21:43:20 +00001406- Patch #1529514: The _ctypes extension is now compiled on more
1407 openbsd target platforms.
1408
Tim Peters9cab5932006-07-28 00:30:00 +00001409- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1410 a memory leak, affecting pickles and deep copies.
1411
Tim Petersbc24eee2006-07-27 01:14:53 +00001412- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1414
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001415- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1416
Thomas Hellerce049a02006-07-14 17:51:14 +00001417- Patch #1521817: Index range checking on ctypes arrays containing
1418 exactly one element enabled again. This allows iterating over these
1419 arrays, without the need to check the array size before.
1420
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001421- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001422 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001423 /dev/null in certain cases; this is now fixed.
1424
Thomas Heller47d7a062006-07-12 08:43:47 +00001425- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1426 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001427
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001428- Because of a misspelled preprocessor symbol, ctypes was always
1429 compiled without thread support; this is now fixed.
1430
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001431- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1432 methods now allow their database parameter to be None as the
1433 sleepycat API allows.
1434
Matt Flemingec926502006-07-28 11:27:27 +00001435- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1436 bluetooth API compared with Linux and FreeBSD.
1437
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001438Tests
1439-----
1440
1441- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1442 how long the test file should take to play. Now accepts taking 2.93 secs
1443 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1444
Georg Brandl4793aa32006-07-28 18:31:39 +00001445- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1446 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1447 run via ``regrtest.py``. Now they do.

1456
1457- PythonLauncher now works correctly when the path to the script contains
1458 characters that are treated specially by the shell (such as quotes).
1459
1460- Bug #1527397: PythonLauncher now launches scripts with the working directory
1461 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001462 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001463 expect.

1471Core and builtins
1472-----------------
1473
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001474- Bug #1441486: The literal representation of -(sys.maxint - 1)
1475 again evaluates to a int object, not a long.
1476
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001477- Bug #1501934: The scope of global variables that are locally assigned
1478 using augmented assignment is now correctly determined.
1479
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001480- Bug #927248: Recursive method-wrapper objects can now safely
1481 be released.
1482
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001483- Bug #1417699: Reject locale-specific decimal point in float()
1484 and atof().
1485
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001486- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1487 omit a default "error" argument for NULL pointer. This allows
1488 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001489
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001490- Bug #1519018: 'as' is now validated properly in import statements.
1491
Neal Norwitz28746ab2006-07-09 22:14:42 +00001492- On 64 bit systems, int literals that use less than 64 bits are
1493 now ints rather than longs.
1494
Neal Norwitzed657552006-07-10 00:04:44 +00001495- Bug #1512814, Fix incorrect lineno's when code at module scope
1496 started after line 256.
1497
Tim Peters32a83612006-07-10 21:08:24 +00001498- New function ``sys._current_frames()`` returns a dict mapping thread
1499 id to topmost thread stack frame. This is for expert use, and is
1500 especially useful for debugging application deadlocks. The functionality
1501 was previously available in Fazal Majid's ``threadframe`` extension
1502 module, but it wasn't possible to do this in a wholly threadsafe way from
1503 an extension.

1506-------
1507
Martin v. Löwis77621582006-07-30 13:27:31 +00001508- Bug #1257728: Mention Cygwin in distutils error message about a missing
1509 VS 2003.
1510
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001511- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1512
Tim Peters32a83612006-07-10 21:08:24 +00001513- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001514 environment variable to be set in order to the SDK environment
1515 for finding the compiler, include files, etc.
1516
Martin v. Löwis388a8c22006-07-06 19:28:03 +00001517- Bug #1515998: Properly generate logical ids for files in bdist_msi.
1518
Nick Coghlan2d792252006-07-06 13:47:18 +00001519- warnings.py now ignores ImportWarning by default
1520
Thomas Woutersadd19112006-07-05 11:03:49 +00001521- string.Template() now correctly handles tuple-values. Previously,
1522 multi-value tuples would raise an exception and single-value tuples would
1523 be treated as the value they contain, instead.
1524
Martin v. Löwisede77f52006-07-03 13:01:35 +00001525- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1526 even if some data are received.
1527
Martin v. Löwis45482392006-07-03 12:28:58 +00001528- Bug #1267547: Put proper recursive setup.py call into the
1529 spec file generated by bdist_rpm.
1530
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001531- Bug #1514693: Update turtle's heading when switching between
1532 degrees and radians.
1533
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001534- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001535 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001536
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001537- Bug #1514703: Only setup canvas window in turtle when the canvas
1538 is created.
1539
Martin v. Löwis7596e832006-07-01 15:33:37 +00001540- Bug #1513223: .close() of a _socketobj now releases the underlying
1541 socket again, which then gets closed as it becomes unreferenced.
1542

1544 attribute values.
1545
1546- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1547 sgmllib ('[' and ']' were not accepted).
1548
Georg Brandl1be63af2006-06-28 20:23:25 +00001549- Fix a bug in the turtle module's end_fill function.
1550
Brett Cannon53ab5b72006-06-22 16:49:14 +00001551- Bug #1510580: The 'warnings' module improperly required that a Warning
1552 category be either a types.ClassType and a subclass of Warning. The proper
1553 check is just that it is a subclass with Warning as the documentation states.
1554
Georg Brandlad29e632006-06-21 17:45:17 +00001555- The compiler module now correctly compiles the new try-except-finally
1556 statement (bug #1509132).
1557
Neal Norwitz60373cd2006-06-22 06:30:50 +00001558- The wsgiref package is now installed properly on Unix.
1559
Vinay Sajip28e57612006-07-01 10:45:20 +00001560- A bug was fixed in logging.config.fileConfig() which caused a crash on
1561 shutdown when fileConfig() was called multiple times.
1562
Gerhard Häring762fbd32006-07-02 17:48:30 +00001563- The sqlite3 module did cut off data from the SQLite database at the first
1564 null character before sending it to a custom converter. This has been fixed
1565 now.
1566
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001567Extension Modules
1568-----------------
1569
Tim Peters112aad32006-07-19 00:03:19 +00001570- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1571 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1572 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001573
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001574- Assigning None to pointer type fields in ctypes structures possible
1575 overwrote the wrong fields, this is fixed now.
1576
1577- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1578 on non-Windows platforms.
1579
1580- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1581 integer or long, without range checking.
1582
1583- Patch #1517790: It is now possible to use custom objects in the ctypes
1584 foreign function argtypes sequence as long as they provide a from_param
1585 method, no longer is it required that the object is a ctypes type.
1586
1587- The '_ctypes' extension module now works when Python is configured
1588 with the --without-threads option.
1589
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001590- Bug #1513646: os.access on Windows now correctly determines write
1591 access, again.
1592
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001593- Bug #1512695: cPickle.loads could crash if it was interrupted with
1594 a KeyboardInterrupt.
1595
Neal Norwitza12aa882006-07-06 06:45:08 +00001596- Bug #1296433: parsing XML with a non-default encoding and
1597 a CharacterDataHandler could crash the interpreter in pyexpat.
1598
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001599- Patch #1516912: improve Modules support for OpenVMS.
1600
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001601Build
1602-----
1603
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001604- Automate Windows build process for the Win64 SSL module.
1605
Tim Peters32a83612006-07-10 21:08:24 +00001606- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001607 Previously, the slight difference could cause compilation errors of the
1608 'zlib' module on systems with more than one version of zlib.
1609
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001610- The MSI compileall step was fixed to also support a TARGETDIR
1611 with spaces in it.
1612
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001613- Bug #1517388: sqlite3.dll is now installed on Windows independent
1614 of Tcl/Tk.
1615
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001616- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001617 trying to be installed even though it's empty.

Neal Norwitzb15ac312006-06-29 04:10:08 +00001619Tests
1620-----
1621
1622- Call os.waitpid() at the end of tests that spawn child processes in order
1623 to minimize resources (zombies).
1624
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001625Documentation
1626-------------
1627
Nick Coghlan2d792252006-07-06 13:47:18 +00001628- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1629 documentation for the warnings module.
1630
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001631- Patch #1509163: MS Toolkit Compiler no longer available.
1632
Neal Norwitz56640df2006-07-10 02:36:41 +00001633- Patch #1504046: Add documentation for xml.etree.

1641Core and builtins
1642-----------------
1643
Georg Brandla56b9152006-06-19 06:35:54 +00001644- Patch #1507676: Error messages returned by invalid abstract object operations
1645 (such as iterating over an integer) have been improved and now include the
1646 type of the offending object to help with debugging.
1647
Brett Cannonea3912b2006-06-13 21:46:41 +00001648- Bug #992017: A classic class that defined a __coerce__() method that returned
1649 its arguments swapped would infinitely recurse and segfault the interpreter.
1650
Neal Norwitz909eb122006-06-12 02:13:21 +00001651- Fix the socket tests so they can be run concurrently.
1652
Neal Norwitzb9845e72006-06-12 02:11:18 +00001653- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001654 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001655
Brett Cannon22565aa2006-06-09 22:31:23 +00001656- Bug #532646: object.__call__() will continue looking for the __call__
1657 attribute on objects until one without one is found. This leads to recursion
1658 when you take a class and set its __call__ attribute to an instance of the
1659 class. Originally fixed for classic classes, but this fix is for new-style.
1660 Removes the infinite_rec_3 crasher.
1661
Georg Brandl24250812006-06-09 18:45:48 +00001662- The string and unicode methods startswith() and endswith() now accept
1663 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1664
Brett Cannonde3b0522006-06-08 17:00:45 +00001665- Buffer objects, at the C level, never used the char buffer
1666 implementation even when the char buffer for the wrapped object was
1667 explicitly requested (originally returned the read or write buffer).
1668 Now a TypeError is raised if the char buffer is not present but is
1669 requested.
1670
Georg Brandlddbaa662006-06-04 21:56:52 +00001671- Patch #1346214: Statements like "if 0: suite" are now again optimized
1672 away like they were in Python 2.4.
1673
Georg Brandlb7c8f542006-05-27 12:30:25 +00001674- Builtin exceptions are now full-blown new-style classes instead of
1675 instances pretending to be classes, which speeds up exception handling
1676 by about 80% in comparison to 2.5a2.
1677
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001678- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1679 Unicode 4.1.
1680
Georg Brandlf4ef1162006-05-26 18:03:31 +00001681- Patch #921466: sys.path_importer_cache is now used to cache valid and
1682 invalid file paths for the built-in import machinery which leads to
1683 fewer open calls on startup.
1684
Tim Peters696cf432006-05-24 21:10:40 +00001685- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1686 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1687 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1688 the number of input digits (it was and remains linear-time for bases
1689 2, 4, 8, 16 and 32).
1690
Tim Petersb713ec22006-05-23 18:45:30 +00001691- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1692 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1693 an integer close to ``sys.maxint``. This was repaired by patch
1694 #1335972, which also gives a nice speedup.
1695
Richard Jonescebbefc2006-05-23 18:28:17 +00001696- Patch #1337051: reduced size of frame objects.
1697
1698- PyErr_NewException now accepts a tuple of base classes as its
1699 "base" parameter.
1700
Richard Jones7c88dcc2006-05-23 10:37:38 +00001701- Patch #876206: function call speedup by retaining allocated frame
1702 objects.
1703
Georg Brandl7b90e162006-05-18 07:01:27 +00001704- Bug #1462152: file() now checks more thoroughly for invalid mode
1705 strings and removes a possible "U" before passing the mode to the
1706 C library function.
1707
Neal Norwitz1004a532006-05-15 07:17:23 +00001708- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1709
Neal Norwitz373f0a72006-05-15 07:04:36 +00001710- Bug #1487966: Fix SystemError with conditional expression in assignment
1711
Martin v. Löwis879768d2006-05-11 13:28:43 +00001712- WindowsError now has two error code attributes: errno, which carries
1713 the error values from errno.h, and winerror, which carries the error
1714 values from winerror.h. Previous versions put the winerror.h values
1715 (from GetLastError()) into the errno attribute.
1716
Martin v. Löwis77736712006-05-04 05:51:03 +00001717- Patch #1475845: Raise IndentationError for unexpected indent.
1718
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001719- Patch #1479181: split open() and file() from being aliases for each other.
1720
Tim Peters44bd9862006-06-01 13:49:23 +00001721- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1722 methods were always silently ignored by dictionaries when comparing keys.
1723 They are now passed through (except when using the C API function
1724 ``PyDict_GetItem()``, whose semantics did not change).
1725
1726- Bug #1456209: In some obscure cases it was possible for a class with a
1727 custom ``__eq__()`` method to confuse dict internals when class instances
1728 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1729 No, you don't have any code that did this ;-)

1732-----------------
1733
Trent Mick960a3f82006-06-28 20:30:41 +00001734- Bug #1295808: expat symbols should be namespaced in pyexpat
1735
1736- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1737
Brett Cannon6ee7d012006-06-08 16:23:04 +00001738- Change binascii.hexlify to accept a read-only buffer instead of only a char
1739 buffer and actually follow its documentation.
1740
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001741- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1742
Nick Coghlanc649ec52006-05-29 12:43:05 +00001743- Patch #1478788 (modified version): The functional extension module has
1744 been renamed to _functools and a functools Python wrapper module added.
1745 This provides a home for additional function related utilities that are
1746 not specifically about functional programming. See PEP 309.
1747
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001748- Patch #1493701: performance enhancements for struct module.
1749
Georg Brandl378d5922006-05-17 14:26:50 +00001750- Patch #1490224: time.altzone is now set correctly on Cygwin.
1751
Georg Brandl8d3342b2006-05-16 07:38:27 +00001752- Patch #1435422: zlib's compress and decompress objects now have a
1753 copy() method.
1754
Andrew MacIntyre92913322006-06-13 15:04:24 +00001755- Patch #1454481: thread stack size is now tunable at runtime for thread
1756 enabled builds on Windows and systems with Posix threads support.
1757
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001758- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1759 (up to the system limit of 32K characters).
1760
1761- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1762 As a result, these functions now raise WindowsError instead of OSError.
1763
Tim Peters7a822da2006-05-25 21:50:17 +00001764- ``time.clock()`` on Win64 should use the high-performance Windows
1765 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1766 Windows platforms).
1767
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001768- Calling Tk_Init twice is refused if the first call failed as that
1769 may deadlock.
1770
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001771- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1772 accept it without potentially using an uninitialized pointer.
1773
1774- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1775 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

1780
Gregory P. Smith372b5832006-06-05 18:48:21 +00001781- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1782 parameter is supplied. [SF pybsddb bug #1477863]
1783
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001784- bsddb: the __len__ method of a DB object has been fixed to return correct
1785 results. It could previously incorrectly return 0 in some cases.
1786 Fixes SF bug 1493322 (pybsddb bug 1184012).
1787
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001788- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1789 aborts the db transaction safely when a modifier callback fails.
1790 Fixes SF python patch/bug #1408584.
1791
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001792- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001793 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001794 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1795 database calls that would previously deadlock. [SF python bug #775414]

1826
Tim Peters43898b42006-06-14 04:09:25 +00001827- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1828 guarantee that adjacent triples in the return list always describe
1829 non-adjacent blocks. Previously, a pair of matching blocks could end
1830 up being described by multiple adjacent triples that formed a partition
1831 of the matching pair.

Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001841- The wsgiref package has been added to the standard library.
1842
Nick Coghlan676725d2006-06-08 13:54:49 +00001843- The functions update_wrapper() and wraps() have been added to the functools
1844 module. These make it easier to copy relevant metadata from the original
1845 function when writing wrapper functions.
1846
Tim Petersd6a9eef2006-06-05 01:48:21 +00001847- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1848 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001849
Martin v. Löwis3f767792006-06-04 19:36:28 +00001850- Patch #1359618: Speed up charmap encoder by using a trie structure
1851 for lookup.
1852
Tim Petersd609b1a2006-06-02 23:22:51 +00001853- The functions in the ``pprint`` module now sort dictionaries by key
1854 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1855 if and only if its display required more than one line, although that
1856 wasn't documented. The new behavior increases predictability; e.g.,
1857 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.

Georg Brandlb89316f2006-05-17 15:51:16 +00001869- Patch #1180296: Two new functions were added to the locale module:
1870 format_string() to get the effect of "format % items" but locale-aware,
1871 and currency() to format a monetary number with currency sign.

1884 a couple of issues, notably handling of long file names using the
1885 GNU LONGNAME extension.
1886
1887- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1888 new flag when ``name`` is already the name of an option flag.
1889
1890- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1891 package.
1892

1935-----------------
1936
Thomas Heller1b046642006-04-18 18:51:06 +00001937- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1938 by converting these apis from macros into exported functions again:
1939
1940 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1941 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1942 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne

1944 PyRun_String Py_CompileString
1945
Martin v. Löwis45294a92006-04-18 06:24:08 +00001946- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1947
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001948- All uses of PyStructSequence_InitType have been changed to initialize
1949 the type objects only once, even if the interpreter is initialized
1950 multiple times.
1951
Neal Norwitz61546162006-04-14 05:20:28 +00001952- Bug #1454485, array.array('u') could crash the interpreter. This was
1953 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1954 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1955
1956- Py_UNICODE is unsigned. It was always documented as unsigned, but
1957 due to a bug had a signed value in previous versions.
1958
Tim Peters3a5e8b12006-04-11 01:44:07 +00001959- Patch #837242: ``id()`` of any Python object always gives a positive
1960 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1961 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001962 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001963 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001964
Tim Peters3a5e8b12006-04-11 01:44:07 +00001965 def __hash__(self):
1966 return id(self) # WRONG
1967
1968 because a hash result must be a (short) Python int but it was always
1969 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001970 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001971 was always usable as a hash value before this patch. That's no longer
1972 necessarily so.
1973
1974- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001975 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001976 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001977 #1454844)
1978
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001979- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1980 involving generators that have paused outside of any ``try`` or ``with``
1981 blocks. (In 2.5a1, a paused generator that was part of a reference
1982 cycle could not be garbage collected, regardless of whether it was
1983 paused in a ``try`` or ``with`` block.)

Tim Peters711bf302006-04-25 03:31:36 +00002015- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes

2017 or exception is ignored).
2018
Nick Coghlanda2268f2006-04-24 04:37:15 +00002019- Fixed contextlib.nested to cope with exceptions being raised and
2020 caught inside exit handlers.
2021
Greg Wardab05edc2006-04-23 03:47:58 +00002022- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2023 hex, octal, or binary; add ``append_const`` action; keep going if
2024 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2025 added ``epilog`` for better help generation).
2026
Tim Peters21fbd572006-04-21 21:18:10 +00002027- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2028 called from a thread spawned as a side effect of importing a module.
2029
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002030- The pydoc module now supports documenting packages contained in
2031 .zip or .egg files.
2032
2033- The pkgutil module now has several new utility functions, such
2034 as ``walk_packages()`` to support working with packages that are either
2035 in the filesystem or zip files.
2036
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002037- The mailbox module can now modify and delete messages from
2038 mailboxes, in addition to simply reading them. Thanks to Gregory
2039 K. Johnson for writing the code, and to the 2005 Google Summer of
2040 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002041
Tim Petersc7605f22006-04-17 21:12:33 +00002042- The ``__del__`` method of class ``local`` in module ``_threading_local``
2043 returned before accomplishing any of its intended cleanup.
2044
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002045- Patch #790710: Add breakpoint command lists in pdb.

2075
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00002076- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002077
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002078- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2079 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002080 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002081 CXX from --with-cxx-main, see description in README.
2082
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002083- Patch #1429775: Link extension modules with the shared libpython.
2084
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002085- Fixed a libffi build problem on MIPS systems.
2086
Tim Peters8931ff12006-05-13 23:28:20 +00002087- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2088 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2089 and "%zu" for unsigned integers of type ``size_t``.

Anthony Baxter51bcb682006-04-05 14:51:42 +00002091Tests
2092-----
2093
Nick Coghlanda2268f2006-04-24 04:37:15 +00002094- test_contextlib now checks contextlib.nested can cope with exceptions
2095 being raised and caught inside exit handlers.
2096
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002097- test_cmd_line now checks operation of the -m and -c command switches
2098
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002099- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2100 it separately and by hand. It also wasn't cleaning up its changes to
2101 the current Decimal context.
2102
Thomas Woutersabd08882006-04-26 15:53:30 +00002103- regrtest.py now has a -M option to run tests that test the new limits of
2104 containers, on 64-bit architectures. Running these tests is only sensible
2105 on 64-bit machines with more than two gigabytes of memory. The argument
2106 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +00002114Documentation
2115-------------
2116
Tim Petersb06d28c2006-05-12 01:57:59 +00002117- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2118
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002119- PEP 343: Added Context Types section to the library reference
2120 and attempted to bring other PEP 343 related documentation into
2121 line with the implementation and/or python-dev discussions.
2122
Tim Peters8dc73d22006-04-24 02:03:16 +00002123- Bug #1337990: clarified that ``doctest`` does not support examples
2124 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002127What's New in Python 2.5 alpha 1?
2128=================================
2129
Anthony Baxterebed3f62006-04-03 15:03:44 +00002130*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002131
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002132Core and builtins
2133-----------------
2134
Nick Coghlan43832302006-04-23 17:04:07 +00002135- PEP 338: -m command line switch now delegates to runpy.run_module
2136 allowing it to support modules in packages and zipfiles
2137
Martin v. Löwisc661b882006-04-20 04:54:23 +00002138- On Windows, .DLL is not an accepted file name extension for
2139 extension modules anymore; extensions are only found if they
2140 end in .PYD.
2141
Martin v. Löwisea62d252006-04-03 10:56:49 +00002142- Bug #1421664: sys.stderr.encoding is now set to the same value as
2143 sys.stdout.encoding.
2144
Neal Norwitz92e212f2006-04-03 04:48:37 +00002145- __import__ accepts keyword arguments.
2146
Georg Brandlccadf842006-03-31 18:54:53 +00002147- Patch #1460496: round() now accepts keyword arguments.
2148
Anthony Baxter262c00a2006-03-30 10:53:17 +00002149- Fixed bug #1459029 - unicode reprs were double-escaped.
2150
Hye-Shik Changd478f342006-03-23 12:32:36 +00002151- Patch #1396919: The system scope threads are reenabled on FreeBSD
2152 5.4 and later versions.
2153
Neal Norwitze98ccf62006-03-23 05:39:47 +00002154- Bug #1115379: Compiling a Unicode string with an encoding declaration
2155 now gives a SyntaxError.
2156
Georg Brandlabd1ff82006-03-18 07:59:59 +00002157- Previously, Python code had no easy way to access the contents of a
2158 cell object. Now, a ``cell_contents`` attribute has been added
2159 (closes patch #1170323).
2160
Tim Peterscf79aac2006-03-16 01:14:46 +00002161- Patch #1123430: Python's small-object allocator now returns an arena to
2162 the system ``free()`` when all memory within an arena becomes unused
2163 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2164 freed. Some applications will see a drop in virtual memory size now,
2165 especially long-running applications that, from time to time, temporarily
2166 use a large number of small objects. Note that when Python returns an
2167 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002168 platform C library will in turn return that memory to the operating system.
2169 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002170 appears to be effective at least on Microsoft C and gcc-based systems.
2171 Thanks to Evan Jones for hard work and patience.
2172
Georg Brandl533ff6f2006-03-08 18:09:27 +00002173- Patch #1434038: property() now uses the getter's docstring if there is
2174 no "doc" argument given. This makes it possible to legitimately use
2175 property() as a decorator to produce a read-only property.
2176
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002177- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2178 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2179 of requiring an int or long in slicing and a few other contexts, enabling
2180 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2181
Neal Norwitz995acdf2006-03-07 05:01:00 +00002182- Fixed various bugs reported by Coverity's Prevent tool.
2183
Brett Cannonbf364092006-03-01 04:25:17 +00002184- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2185 new exception base class, BaseException, which has a new message attribute.
2186 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2187 Raising a string exception now raises a DeprecationWarning.
2188
Thomas Woutersfb609f42006-02-28 16:37:25 +00002189- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2190 explicitly relative, using 'from .module import name' to mean 'from the same
2191 package as this module is in. Imports without dots still default to the
2192 old relative-then-absolute, unless 'from __future__ import
2193 absolute_import' is used.
2194
Brett Cannona7446e32006-02-27 23:39:10 +00002195- Properly check if 'warnings' raises an exception (usually when a filter set
2196 to "error" is triggered) when raising a warning for raising string
2197 exceptions.
2198
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002199- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002200 The name was removed from Include/code.h.
2201
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002202- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002203
Guido van Rossum1968ad32006-02-25 22:38:04 +00002204- Patch 1433928:
2205 - The copy module now "copies" function objects (as atomic objects).
2206 - dict.__getitem__ now looks for a __missing__ hook before raising
2207 KeyError.
2208
Tim Peters84ef21c2006-02-28 20:39:06 +00002209- PEP 343: with statement implemented. Needs ``from __future__ import
2210 with_statement``. Use of 'with' as a variable will generate a warning.
2211 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002212 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002213 The following objects have __context__ methods:
2214 - The built-in file type.
2215 - The thread.LockType type.
2216 - The following types defined by the threading module:
2217 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2218 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002219
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002220- Fix the encodings package codec search function to only search
2221 inside its own package. Fixes problem reported in patch #1433198.
2222
2223 Note: Codec packages should implement and register their own
2224 codec search function. PEP 100 has the details.
2225
Tim Peters9ea89d22006-06-04 03:26:02 +00002226- PEP 353: Using ``Py_ssize_t`` as the index type.
2227
2228- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2229 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2230 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2231 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2232 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002233
Neal Norwitzfc76d632006-01-10 06:03:13 +00002234- Patch #1400181, fix unicode string formatting to not use the locale.
2235 This is how string objects work. u'%f' could use , instead of .
2236 for the decimal point. Now both strings and unicode always use periods.
2237
Neal Norwitz671b9e32006-01-09 07:07:12 +00002238- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2239 configure would break checking curses.h.
2240
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002241- Bug #959576: The pwd module is now builtin. This allows Python to be
2242 built on UNIX platforms without $HOME set.
2243
Neal Norwitzc10978f2005-12-19 06:07:16 +00002244- Bug #1072182, fix some potential problems if characters are signed.
2245
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002246- Bug #889500, fix line number on SyntaxWarning for global declarations.
2247
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002248- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2249
Neal Norwitze7214a12005-12-18 05:03:17 +00002250- Support for converting hex strings to floats no longer works.
2251 This was not portable. float('0x3') now raises a ValueError.
2252
Barry Warsaw2a38a862005-12-18 01:27:35 +00002253- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002254 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002255 is now displayed in interactive prompt banner.
2256
Georg Brandlfa166682005-12-17 21:45:17 +00002257- Implementation of PEP 341 - Unification of try/except and try/finally.
2258 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002259 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002260
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002261- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2262 now encodes backslash correctly.
2263
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002264- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2265
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002266- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002267 and long longs.
2268
Neal Norwitz67715f02005-11-09 06:59:35 +00002269- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002270 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002271 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002272
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002273- Replaced most Unicode charmap codecs with new ones using the
2274 new Unicode translate string feature in the builtin charmap
2275 codec; the codecs were created from the mapping tables available
2276 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2277 encodings now include a mapping for the Apple logo)
2278
Tim Peterse3547fd2005-12-16 23:13:57 +00002279- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002280
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002281- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002282
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002283- A new AST parser implementation was completed. The abstract
2284 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002285 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002286
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002287- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002288 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2289
Neal Norwitz708e51a2005-10-03 04:48:15 +00002290- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2291
Neal Norwitz11bd1192005-10-03 00:54:56 +00002292- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2293 Provide a warning when a directory is passed on the command line.
2294
Neal Norwitz40d37812005-10-02 01:48:49 +00002295- Fix segfault with invalid coding.
2296
2297- SF bug #772896: unknown encoding results in MemoryError.
2298
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002299- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002300 supported a __len__() method which evaluated to False when the iterator
2301 was empty.
2302
Guido van Rossum630db602005-09-20 18:49:54 +00002303- On 64-bit platforms, when __len__() returns a value that cannot be
2304 represented as a C int, raise OverflowError.
2305
Skip Montanarof8948ca2005-09-19 03:54:46 +00002306- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002307 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002308
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002309- SF bug #893549: parsing keyword arguments was broken with a few format
2310 codes.
2311
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002312- Changes donated by Elemental Security to make it work on AIX 5.3
2313 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2314 bug #105470: test_pwd fails on 64bit system (Opteron).
2315
Guido van Rossum539c6622005-09-14 17:49:54 +00002316- Changes donated by Elemental Security to make it work on HP-UX 11 on
2317 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2318
Georg Brandl4550b8d2005-08-26 06:43:52 +00002319- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002320 (fixes bug #1119418).
2321
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002322- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2323
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002324- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2325 exceptions that cause a function to exit.
2326
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002327- The implementation of set() and frozenset() was revised to use its
2328 own internal data structure. Memory consumption is reduced by 1/3
2329 and there are modest speed-ups as well. The API is unchanged.
2330
Tim Petersde7990b2005-07-17 23:45:23 +00002331- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2332
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002333- SF bug #1229429: PyObject_CallMethod failed to decrement some
2334 reference counts in some error exit cases.
2335
Tim Petersecc6e6a2005-07-10 22:30:55 +00002336- SF bug #1185883: Python's small-object memory allocator took over
2337 a block managed by the platform C library whenever a realloc specified
2338 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002339 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002340 portable way to copy data from the C-managed block into Python's
2341 small-object space without risking a memory fault. Python's small-object
2342 realloc now leaves such blocks under the control of the platform C
2343 realloc.

Michael W. Hudsonb8963812005-07-05 15:21:58 +00002345- SF bug #1232517: An overflow error was not detected properly when
2346 attempting to convert a large float to an int in os.utime().
2347
Raymond Hettinger3296e692005-06-29 23:29:56 +00002348- SF bug #1224347: hex longs now print with lowercase letters just
2349 like their int counterparts.
2350
Michael W. Hudson188d4362005-06-20 16:52:57 +00002351- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2352 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2353 interpreter states; back out that fix and do a better job (see
2354 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2355 for a longer write-up of the problem).
2356
Michael W. Hudsondf888462005-06-03 14:41:55 +00002357- SF patch #1180995: marshal now uses a binary format by default when
2358 serializing floats.
2359
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002360- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2361 the routines that promise to produce IEEE 754 binary representations
2362 of floats now simply copy bytes around.
2363
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002364- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2365 278.
2366
Brett Cannonc3647ac2005-04-26 03:45:26 +00002367- patch #1109424: int, long, float, complex, and unicode now check for the
2368 proper magic slot for type conversions when subclassed. Previously the
2369 magic slot was ignored during conversion. Semantics now match the way
2370 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002371 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002372 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002373 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002374
Barry Warsawc8d907c2005-04-19 23:43:40 +00002375- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2376 NULL, now raise an AttributeError when attempting to set or delete the
2377 attribute. Previously a TypeError was raised, but this was inconsistent
2378 with the equivalent pure-Python implementation.
2379
Michael W. Hudson774479c2005-04-18 08:46:17 +00002380- It is now safe to call PyGILState_Release() before
2381 PyEval_InitThreads() (note that if there is reason to believe there
2382 are multiple threads around you still must call PyEval_InitThreads()
2383 before using the Python API; this fix is for extension modules that
2384 have no way of knowing if Python is multi-threaded yet).
2385
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002386- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2387 disabled caused a crash.
2388
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002389- Bug #1165306: instancemethod_new allowed the creation of a method
2390 with im_class == im_self == NULL, which caused a crash when called.
2391
Tim Petersecc6e6a2005-07-10 22:30:55 +00002392- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002393 fixes the crash seen in bug #1165761
2394
Raymond Hettinger96229b12005-03-11 06:49:40 +00002395- Added two new builtins, any() and all().
2396
Brett Cannon409d8f22005-03-05 06:47:57 +00002397- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002398 (e.g., ``class C(): pass`` is no longer a syntax error).
2399 Patch #1176012 added support to the 'parser' module and 'compiler' package
2400 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002401
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002402- Patch #1115086: Support PY_LONGLONG in structmember.
2403
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002404- Bug #1155938: new style classes did not check that __init__() was
2405 returning None.
2406
Tim Petersecc6e6a2005-07-10 22:30:55 +00002407- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002408 ('\') with a specific error message.
2409
Martin v. Löwisff232d72005-03-03 09:24:38 +00002410- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2411
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002412- Bug #1124295: the __name__ attribute of file objects was
2413 inadvertently made inaccessible in restricted mode.
2414
Tim Petersecc6e6a2005-07-10 22:30:55 +00002415- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002416 an ferror() call.
2417
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002418- min() and max() now support key= arguments with the same meaning as in
2419 list.sort().
2420
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002421- The peephole optimizer now performs simple constant folding in expressions:
2422 (2+3) --> (5).
2423
Raymond Hettingera422c342005-01-11 03:03:27 +00002424- set and frozenset objects can now be marshalled. SF #1098985.
2425
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002426- Bug #1077106: Poor argument checking could cause memory corruption
2427 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002428
Jeremy Hyltonab630502005-02-04 18:44:06 +00002429- The parser did not complain about future statements in illegal
2430 positions. It once again reports a syntax error if a future
2431 statement occurs after anything other than a doc string.
2432
Neil Schemenauercf52c072005-08-12 17:34:58 +00002433- Change the %s format specifier for str objects so that it returns a
2434 unicode instance if the argument is not an instance of basestring and
2435 calling __str__ on the argument returns a unicode instance.
2436
Tim Petersf4e69282006-02-27 17:15:31 +00002437- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2438 current thread state when the auto-GIL-state machinery knows about
2439 it (since the thread state is being deleted, continuing to remember it
2440 can't help, but can hurt if another thread happens to get created with
2441 the same thread id).
2442
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002443Extension Modules

2460
2461- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2462
2463- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002464 is deprecated. The undocumented re.engine variable no longer exists.
2465

2468
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002469- The unicodedata module was updated to the 4.1 version of the Unicode
2470 database. The 3.2 version is still available as unicodedata.db_3_2_0
2471 for applications that require this specific version (such as IDNA).
2472
Neal Norwitzb62c4332006-03-04 18:35:47 +00002473- The timing module is no longer built by default. It was deprecated
2474 in PEP 4 in Python 2.0 or earlier.
2475
Guido van Rossum1968ad32006-02-25 22:38:04 +00002476- Patch 1433928: Added a new type, defaultdict, to the collections module.

2478
Georg Brandldbd83392006-02-20 09:42:33 +00002479- Bug #854823: socketmodule now builds on Sun platforms even when

2494
Martin v. Löwis14694662006-02-03 12:54:16 +00002495- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2496 are reported, the limit on path name lengths is removed, and stat reports
2497 WindowsError now (instead of OSError).
2498

2574 the request code argument, which results in more C-like behaviour
2575 for large or negative values.
2576
Tim Petersecc6e6a2005-07-10 22:30:55 +00002577- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

2618 args tuple returned by __reduce__().
2619
Raymond Hettingerb2594052004-12-05 09:25:51 +00002620- itertools.islice() now accepts None for the start and step arguments.
2621 This allows islice() to work more readily with slices:

Tim Peters112aad32006-07-19 00:03:19 +00002632
Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002633- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2634 been renamed to have only a single underscore prefix. This was done to
2635 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002636
Nick Coghlan43832302006-04-23 17:04:07 +00002637- PEP 338: new module runpy defines a run_module function to support
2638 executing modules which provide access to source code or a code object
2639 via the PEP 302 import mechanisms.
2640
Anthony Baxter93f5b932006-04-03 08:05:07 +00002641- The email module's parsedate_tz function now sets the daylight savings
2642 flag to -1 (unknown) since it can't tell from the date whether it should

2649 in attribute values.
2650
Anthony Baxterc51ee692006-04-01 00:57:31 +00002651- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002652 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002653 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002654 module will not be built.
2655
Tim Petersc17976e2006-04-01 00:26:53 +00002656- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2657 aren't officially supported here, and trying to use them will probably
2658 raise an exception some day. But dicts have been allowed, and "mostly
2659 worked", so support for them won't go away without warning.
2660
Georg Brandl338ef7d2006-03-31 18:42:16 +00002661- Bug #1445068: getpass.getpass() can now be given an explicit stream
2662 argument to specify where to write the prompt.
2663
Georg Brandl22ec80b2006-03-31 18:25:44 +00002664- Patch #1462313, bug #1443328: the pickle modules now can handle classes
2665 that have __private names in their __slots__.
2666

2673 to make it easier to monitor when daemon threads have completed
2674 processing all enqueued tasks. Patch #1455676.
2675
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002676- popen2.Popen objects now preserve the command in a .cmd attribute.
2677
Thomas Hellerc61c0492006-03-22 10:09:27 +00002678- Added the ctypes ffi package.
2679
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002680- email 4.0 package now integrated. This is largely the same as the email 3.0
2681 package that was included in Python 2.3, except that PEP 8 module names are
2682 now used (e.g. mail.message instead of email.Message). The MIME classes
2683 have been moved to a subpackage (e.g. email.mime.text instead of
2684 email.MIMEText). The old names are still supported for now. Several
2685 deprecated Message methods have been removed and lots of bugs have been
2686 fixed. More details can be found in the email package documentation.
2687
Walter Dörwald40108c92006-03-27 08:15:44 +00002688- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2689 (a subclass of tuple) that provides incremental decoders and encoders
2690 (a way to use stateful codecs without the stream API). Python functions
2691 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2692 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2693 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002694
Walter Dörwald067db482006-03-15 22:17:27 +00002695- Patch #1359365: Calling next() on a closed StringIO.String object raises
2696 a ValueError instead of a StopIteration now (like file and cString.String do).
2697 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2698 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002699
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002700- A regrtest option -w was added to re-run failed tests in verbose mode.

2773 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2774 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2775 Ronald L. Rivest offered this advice for Python:
2776
2777 "The consensus of researchers in this area (at least as
2778 expressed at the NIST Hash Function Workshop 10/31/05),
2779 is that SHA-256 is a good choice for the time being, but
2780 that research should continue, and other alternatives may
2781 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002782
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002783- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandl5284b532005-06-26 22:54:58 +00002867
Georg Brandl2f210b62005-06-26 22:09:06 +00002868- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
2869
Georg Brandlfbff1bc2005-06-26 21:36:25 +00002870- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
2871 error messages.
2872
Georg Brandl379f99d2005-06-26 21:09:38 +00002873- Bug #1108948: Cookie.py produced invalid JavaScript code.
2874
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00002875- The tokenize module now detects and reports indentation errors.
2876 Bug #1224621.
2877
Raymond Hettinger68c04532005-06-10 11:05:19 +00002878- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002879 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002880 the generate_tokens() function now accepts a callable argument that
2881 terminates by raising StopIteration.
2882
Georg Brandl9166e1a2005-06-04 09:20:03 +00002883- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2884
Georg Brandl268e61c2005-06-03 14:28:50 +00002885- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2886 component of the path.
2887
Skip Montanaro174dd222005-05-14 20:54:16 +00002888- Patch #1120353: The xmlrpclib module provides better, more transparent,
2889 support for datetime.{datetime,date,time} objects. With use_datetime set
2890 to True, applications shouldn't have to fiddle with the DateTime wrapper
2891 class at all.
2892
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002893- distutils.commands.upload was added to support uploading distribution
2894 files to PyPI.
2895
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002896- distutils.commands.register now encodes the data as UTF-8 before posting
2897 them to PyPI.
2898
Raymond Hettinger267b8682005-03-27 10:47:39 +00002899- decimal operator and comparison methods now return NotImplemented
2900 instead of raising a TypeError when interacting with other types. This
2901 allows other classes to implement __radd__ style methods and have them
2902 work as expected.
2903
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002904- Bug #1163325: Decimal infinities failed to hash. Attempting to
2905 hash a NaN raised an InvalidOperation instead of a TypeError.
2906
Tim Petersecc6e6a2005-07-10 22:30:55 +00002907- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002908 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2909
Martin v. Löwis00a73e72005-03-04 19:40:34 +00002910- Patch #1043890: Add extractall method to tarfile.

2913 to build.
2914
Martin v. Löwis637431b2005-03-03 23:12:42 +00002915- Patch #1103407: Properly deal with tarfile iterators when untarring

2939
Raymond Hettingerbab41432005-02-05 01:31:19 +00002940- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2941
Guido van Rossumd0641422005-02-03 15:01:24 +00002942- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2943 disables recursive traversal through instance attributes, which can
2944 be exploited in various ways.
2945
Tim Peterse3547fd2005-12-16 23:13:57 +00002946- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002947 flags on the HTTP listening socket.
2948
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002949- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2950 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2951
Fred Drakefbdeaad2006-07-29 16:56:15 +00002952- Patches #893642, #1039083: add allow_none, encoding arguments to
2953 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002954
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002955- Bug #1110478: Revert os.environ.update to do putenv again.
2956
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002957- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2958
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002959- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2960
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002961- Enhancements to the csv module:
2962
2963 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002964 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002965 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002966 + Dialect parameter parsing has been re-implemented to improve error
2967 reporting.
2968 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2969 dictates.
2970 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002971 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002972 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002973 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2974 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002975 + reader now allows \r characters to be quoted (previously it only allowed
2976 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002977 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002978 + Dialect classes passed to the module are no longer instantiated by
2979 the module before being parsed (the former validation scheme required
2980 this, but the mechanism was unreliable).
2981 + The dialect registry now contains instances of the internal
2982 C-coded dialect type, rather than references to python objects.
2983 + the internal c-coded dialect type is now immutable.
2984 + register_dialect now accepts the same keyword dialect specifications
2985 as the reader and writer, allowing the user to register dialects
2986 without first creating a dialect class.
2987 + a configurable limit to the size of parsed fields has been added -
2988 previously, an unmatched quote character could result in the entire
2989 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002990 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002991 the parser field size limit (returning the former limit). The initial
2992 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002993 + A line_num attribute has been added to the reader object, which tracks
2994 the number of lines read from the source iterator. This is not
2995 the same as the number of records returned, as records can span
2996 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002997 + reader and writer objects were not being registered with the cyclic-GC.
2998 This has been fixed.
2999
Brett Cannone6539c42005-01-08 02:43:53 +00003000- _DummyThread objects in the threading module now delete self.__block that is
3001 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3002 lock primitives tend to be limited in number and thus should not be wasted on
3003 a _DummyThread object. Fixes bug #1089632.
3004
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003005- The imghdr module now detects Exif files.
3006
Raymond Hettinger6065d322004-12-20 23:51:53 +00003007- StringIO.truncate() now correctly adjusts the size attribute.
3008 (Bug #951915).
3009
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003010- locale.py now uses an updated locale alias table (built using
3011 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3012 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003013 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003014
Raymond Hettinger3557f422004-12-07 12:02:02 +00003015- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3016
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003017- the pickle module no longer accepts the deprecated None option in the
3018 args tuple returned by __reduce__().
3019
Brett Cannon84667c02004-12-07 03:25:18 +00003020- optparse now optionally imports gettext. This allows its use in setup.py.
3021
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003022- the pickle module no longer uses the deprecated bin parameter.
3023
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003024- the shelve module no longer uses the deprecated binary parameter.
3025
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003026- the pstats module no longer uses the deprecated ignore() method.
3027
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003028- the filecmp module no longer uses the deprecated use_statcache argument.
3029
Raymond Hettinger664347b2004-12-04 21:21:53 +00003030- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3031 extended or overridden by subclasses. Formerly, the subclassed method would
3032 be ignored by the rest of the module. (Bug #1078905).
3033
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003034- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003035 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003036
Walter Dörwald36733692004-12-22 12:50:50 +00003037- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3038 once when a size argument is given. This prevents a buffer overflow in the
3039 tokenizer with very long source lines.
3040
Barry Warsaw538561e2006-01-01 21:48:54 +00003041- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3042 immediately after creating the object, without any intervening
3043 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003044
Skip Montanaro05885812005-01-16 20:48:27 +00003045- The reconvert.quote function can now emit triple-quoted strings. The
3046 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003047
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003048- ``UserString.MutableString`` now supports negative indices in
3049 ``__setitem__`` and ``__delitem__``
3050
Greg Ward40407942005-03-05 02:53:17 +00003051- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3052 correctly.
3053
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003054- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3055 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3056 character even if the user has passed a size parameter to get a proper
3057 line ending. Remove the special handling of a "\r\n" that has been split
3058 between two lines.
3059
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003060- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3061 about illegal code points. The codec now supports PEP 293 style error
3062 handlers.
3063
Walter Dörwald78a78b02005-09-01 12:04:29 +00003064- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003065 from the input stream, so that the output is a byte string in the correct
3066 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003067
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003068- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3069 considering it exactly like a '*'.
3070
Walter Dörwald007f8df2005-10-09 19:42:27 +00003071- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3072 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003073
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003074- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3075
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003076- Patch #1413711: Certain patterns of differences were making difflib
3077 touch the recursion limit.
3078
Walter Dörwald58917a62006-03-31 15:26:22 +00003079- Bug #947906: An object oriented interface has been added to the calendar
3080 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003081 called as a script (e.g. via ``python -mcalendar``). Localized month and
3082 weekday names can be ouput (even if an exotic encoding is used) using
3083 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003084

Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003099- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3100 The zlib module is now builtin on Windows.
3101
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003102- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3103
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003104- Bug #1189330: configure did not correctly determine the necessary
3105 value of LINKCC if python was built with GCC 4.0.
3106
Trent Mick8321b422005-07-26 02:29:21 +00003107- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3108 vulnerability in zlib 1.2.1 and 1.2.2.
3109
Brett Cannon08cd5982005-04-24 22:26:38 +00003110- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3111 flags that change binary compatibility. Changes were also made to
3112 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003113 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003114
Bob Ippolitoed233462005-03-29 13:47:59 +00003115- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3116 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3117 no longer exists). This configure patch makes things right.
3118
Martin v. Löwise2713be2005-03-08 15:03:08 +00003119- Bug #1158607: Build with --disable-unicode again.
3120
Brett Cannon46d96232005-02-16 00:07:19 +00003121- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3122 defined. Discovered as a result of not being able to build on OS X.
3123
Brett Cannon516592f2004-12-07 00:42:59 +00003124- setup.py now uses the directories specified in LDFLAGS using the -L option
3125 and in CPPFLAGS using the -I option for adding library and include
3126 directories, respectively, for compiling extension modules against. This has
3127 led to the core being compiled using the values in CPPFLAGS. It also removes
3128 the need for the special-casing of both DarwinPorts and Fink for darwin since
3129 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3130 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3131 Fink, ``-I/opt/local/include`` for DarwinPorts).

Brett Cannon43802422005-02-10 20:48:03 +00003133- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3134 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3135 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3136 Closes bug #1096244. Thanks Gregory Bond.

Tim Petersc9d78aa2006-03-26 23:27:58 +00003141- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3142 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3143 is obtained via the ``PyObject_`` family, it must be released via the
3144 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3145 always been officially true, but when Python's small-object allocator was
3146 introduced, an attempt was made to cater to a few extension modules
3147 discovered at the time that obtained memory via ``PyObject_New`` but
3148 released it via ``PyMem_DEL``. It's years later, and if such code still
3149 exists it will fail now (probably with segfaults, but calling wrong
3150 low-level memory management functions can yield many symptoms).

Raymond Hettingerbeb31012005-08-16 03:47:52 +00003152- Added a C API for set and frozenset objects.

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003156- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3157 mapping argument now. This string is used as a mapping table. Byte values
3158 greater than the length of the string and 0xFFFE are treated as undefined
3159 mappings.
