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

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().

133-----------------
134

138
Amaury Forgeot d'Arc3e5f8a62008-02-08 01:05:21 +0000139- Issue #2045: Fix an infinite recursion triggered when printing a subclass of

141
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000142- Issue #1920: "while 0" statements were completely removed by the compiler,
143 even in the presence of an "else" clause, which is supposed to be run when
144 the condition is false. Now the compiler correctly emits bytecode for the
145 "else" suite.
146

961-----------------
962
Neal Norwitz0bcafac2006-09-11 08:51:17 +0000963- Make _PyGILState_NoteThreadState() static, it was not used anywhere
964 outside of pystate.c and should not be necessary.
965
Brett Cannon19d76c52006-09-09 07:18:44 +0000966- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
967 allows calling unicode() on exceptions classes directly to succeed.
968
Georg Brandlecab6232006-09-06 06:47:02 +0000969- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
970 Also make sure that every exception class has __module__ set to
971 'exceptions'.
972
Georg Brandl37a9e572006-09-06 06:09:34 +0000973- Bug #1550983: emit better error messages for erroneous relative

983
Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000984- The return tuple from str.rpartition(sep) is (tail, sep, head) where
985 head is the original string if sep was not found.
986
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000987- Bug #1520864: unpacking singleton tuples in list comprehensions and
988 generator expressions (x for x, in ... ) works again. Fixing this problem
989 required changing the .pyc magic number. This means that .pyc files
990 generated before 2.5c2 will be regenerated.

Neal Norwitz24b6f202006-09-05 04:43:56 +00001105- Fix infinite recursion when subclassing long and overriding __hash__.
1106
1107- Fix concatenation (+=) of long strings.
1108
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001109- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001110 compared equal or unequal to a string and a UnicodeDecodeError
1111 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001112
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001113 Instead, the equal (==) and unequal (!=) comparison operators will
1114 now issue a UnicodeWarning and interpret the two objects as
1115 unequal. The UnicodeWarning can be filtered as desired using
1116 the warning framework, e.g. silenced completely, turned into an
1117 exception, logged, etc.
1118
1119 Note that compare operators other than equal and unequal will still
1120 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001121
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001122- Fix segfault when doing string formatting on subclasses of long.
1123
1124- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1125 with new-style classes.
1126
1127- Fix bug related to __len__ functions returning negative values with
1128 classic classes.
1129
1130- Patch #1538606, Fix __index__() clipping. There were some problems
1131 discovered with the API and how integers that didn't fit into Py_ssize_t
1132 were handled. This patch attempts to provide enough alternatives
1133 to effectively use __index__.
1134
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001135- Bug #1536021: __hash__ may now return long int; the final hash
1136 value is obtained by invoking hash on the long int.
1137
Thomas Hellerab1049c2006-08-08 17:37:00 +00001138- Bug #1536786: buffer comparison could emit a RuntimeWarning.

1141 sys.stdin is closed.
1142
Thomas Heller74d36f02006-08-04 18:17:40 +00001143- On Windows, the PyErr_Warn function is now exported from
1144 the Python dll again.
1145
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001146- Bug #1191458: tracing over for loops now produces a line event
1147 on each iteration. Fixing this problem required changing the .pyc
1148 magic number. This means that .pyc files generated before 2.5c1
1149 will be regenerated.
1150
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001151- Bug #1333982: string/number constants were inappropriately stored
1152 in the byte code and co_consts even if they were not used, ie
1153 immediately popped off the stack.
1154
Georg Brandle9462c72006-08-04 18:03:37 +00001155- Fixed a reference-counting problem in property().

Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001161- Fix a bug in the ``compiler`` package that caused invalid code to be
1162 generated for generator expressions.
1163
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001164- The distutils version has been changed to 2.5.0. The change to
1165 keep it programmatically in sync with the Python version running
1166 the code (introduced in 2.5b3) has been reverted. It will continue
1167 to be maintained manually as static string literal.
1168
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001169- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001170 and this cannot be converted to the required C type, an exception is
1171 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001172 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001173
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001174- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001175 an exception.
1176
Tim Peterscbdd3502006-09-05 01:47:53 +00001177- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001178 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001179 workarounds for clocks with low resolution, to stop the code yielding
1180 duplicate UUIDs.
1181
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001182- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1183 before raising SystemExit, allowing IDLE to honor quit() and exit().
1184
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001185- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1186
Georg Brandl7a1af772006-08-14 21:55:28 +00001187- Patch #1536071: trace.py should now find the full module name of a

1196 str(exception) raised an exception.
1197
Neil Schemenauer06ded092006-08-04 16:20:30 +00001198- Fix a bug in the ``compiler`` package that caused invalid code to be
1199 generated for nested functions.

Thomas Heller1ce433e2006-08-14 16:20:04 +00001212- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1213 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1214
Thomas Heller86720042006-08-14 11:17:48 +00001215- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1216 uses the _as_parameter_ attribute when objects are passed to foreign
1217 function calls. The ctypes version number was changed to 1.0.1.
1218
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001219- Bug #1530559, struct.pack raises TypeError where it used to convert.
1220 Passing float arguments to struct.pack when integers are expected
1221 now triggers a DeprecationWarning.

1256-----
1257
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001258- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1259
Tim Peters4643c2f2006-08-10 22:45:34 +00001260- Bug #1069160. Internal correctness changes were made to
1261 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1262 the documentation was changed to state that the return value
1263 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001266What's New in Python 2.5 beta 3?
1267================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001268
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001269*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001270
1271Core and builtins
1272-----------------
1273
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001274- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001275 returned a long (see PEP 353).
1276
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001277- Bug #1515471: string.replace() accepts character buffers again.
1278
Neal Norwitz07aadb12006-07-30 06:55:48 +00001279- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1280 This provides the proper warning for struct.pack().
1281 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1282
Neal Norwitz0d62a062006-07-30 06:53:31 +00001283- Patch #1531113: Fix augmented assignment with yield expressions.
1284 Also fix a SystemError when trying to assign to yield expressions.
1285
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001286- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1287 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1288 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1289 excessive filesystem operations during imports.
1290
Tim Petersbc24eee2006-07-27 01:14:53 +00001291- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1292 operations on signed longs that are formally undefined by C.
1293 Unfortunately, at least one compiler now cares about that, so complicated
1294 the code to make that compiler happy again.
1295
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001296- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1297
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001298- Patch #1232023: Stop including current directory in search
1299 path on Windows.
1300
Neal Norwitze1fdb322006-07-21 05:32:28 +00001301- Fix some potential crashes found with failmalloc.
1302
Neal Norwitze7563102006-07-17 01:00:16 +00001303- Fix warnings reported by Klocwork's static analysis tool.
1304
Neal Norwitz84be93b2006-07-16 01:50:38 +00001305- Bug #1512814, Fix incorrect lineno's when code within a function
1306 had more than 255 blank lines.
1307
Georg Brandl9dceedb2006-07-12 15:31:17 +00001308- Patch #1521179: Python now accepts the standard options ``--help`` and
1309 ``--version`` as well as ``/?`` on Windows.
1310
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001311- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001312 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001313 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001314
Tim Peters112aad32006-07-19 00:03:19 +00001315- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001316 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001317 new ``sys._current_frames()`` returns a dictionary with one entry,
1318 mapping the faux "thread id" 0 to the current frame.
1319
Ronald Oussoren3075e162006-07-25 20:28:55 +00001320- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001321
Ronald Oussoren3075e162006-07-25 20:28:55 +00001322
Neal Norwitza1f10902006-07-12 07:28:29 +00001323Library
1324-------
1325
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001326- Correction of patch #1455898: In the mbcs decoder, set final=False
1327 for stream decoder, but final=True for the decode function.
1328
Georg Brandl07fec3a2006-08-01 18:49:24 +00001329- os.urandom no longer masks unrelated exceptions like SystemExit or
1330 KeyboardInterrupt.
1331
Tim Peters4643c2f2006-08-10 22:45:34 +00001332- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001333 shutil.copytree on Windows
1334
Georg Brandle34ac7c2006-07-30 11:07:23 +00001335- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1336 refers to file descriptors, not file objects.
1337
Tim Peterscbdd3502006-09-05 01:47:53 +00001338- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001339 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001340 #1513611, and probably others.
1341
Georg Brandledd9b0d2006-07-29 09:33:26 +00001342- Bug #1441397: The compiler module now recognizes module and function
1343 docstrings correctly as it did in Python 2.4.
1344
Tim Peters6f681472006-07-27 23:44:37 +00001345- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1346 lost that tests are sorted by name before being run. This rarely
1347 matters for well-written tests, but can create baffling symptoms if
1348 side effects from one test to the next affect outcomes. ``DocTestFinder``
1349 has been changed to sort the list of tests it returns.
1350
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001351- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001352 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001353
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001354- Bug #978833: Really close underlying socket in _socketobject.close.
1355
Georg Brandldb232dc2006-08-20 13:15:43 +00001356- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1357 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001358
Georg Brandlcf0c1722006-07-26 07:23:32 +00001359- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1360 to recursive calls and call it with the failing package name.
1361
Martin v. Löwis0b483032006-07-25 09:53:12 +00001362- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1363
Georg Brandlc13c34c2006-07-24 14:09:56 +00001364- Patch #1515343: Fix printing of deprecated string exceptions with a
1365 value in the traceback module.
1366
Greg Ward48fae7a2006-07-23 16:05:51 +00001367- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1368
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001369- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1370
Brett Cannoncaebe222006-07-18 04:41:36 +00001371- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1372 argument tuple. For arguments where zero is illegal, the value is forced to
1373 the minimum value that is correct. This is to support an undocumented but
1374 common way people used to fill in inconsequential information in the time
1375 tuple pre-2.4.
1376
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001377- Patch #1220874: Update the binhex module for Mach-O.
1378
Barry Warsawb110bad2006-07-21 14:51:07 +00001379- The email package has improved RFC 2231 support, specifically for
1380 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1381 (name*0=<blah>) parameter continuations. This may change the types of
1382 values returned from email.message.Message.get_param() and friends.
1383 Specifically in some cases where non-encoded continuations were used,
1384 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1385 will just return the string (since non-encoded continuations don't have
1386 charset and language parts).
1387
1388 Also, whereas % values were decoded in all parameter continuations, they are
1389 now only decoded in encoded parameter parts.
1390
Ronald Oussoren3075e162006-07-25 20:28:55 +00001391- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1392
1393- Bug #1517996: IDLE now longer shows the default Tk menu when a
1394 path browser, class browser or debugger is the frontmost window on MacOS X
1395
Barry Warsaw00decd72006-07-27 23:43:15 +00001396- Patch #1520294: Support for getset and member descriptors in types.py,
1397 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1398 of an object against these built-in types and more importantly, for getting
1399 their docstrings printed in the interactive interpreter's help() function.

1404
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001405- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1406 a socket operation on a socket with a timeout, the exception will be
1407 caught correctly. Previously, the exception was not caught.
1408
Thomas Heller1393d6a2006-07-28 21:43:20 +00001409- Patch #1529514: The _ctypes extension is now compiled on more
1410 openbsd target platforms.
1411
Tim Peters9cab5932006-07-28 00:30:00 +00001412- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1413 a memory leak, affecting pickles and deep copies.
1414
Tim Petersbc24eee2006-07-27 01:14:53 +00001415- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001416 Paul Eggert.
1417
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001418- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1419
Thomas Hellerce049a02006-07-14 17:51:14 +00001420- Patch #1521817: Index range checking on ctypes arrays containing
1421 exactly one element enabled again. This allows iterating over these
1422 arrays, without the need to check the array size before.
1423
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001424- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001425 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001426 /dev/null in certain cases; this is now fixed.
1427
Thomas Heller47d7a062006-07-12 08:43:47 +00001428- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1429 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001430
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001431- Because of a misspelled preprocessor symbol, ctypes was always
1432 compiled without thread support; this is now fixed.
1433
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001434- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1435 methods now allow their database parameter to be None as the
1436 sleepycat API allows.
1437
Matt Flemingec926502006-07-28 11:27:27 +00001438- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1439 bluetooth API compared with Linux and FreeBSD.

1442-----
1443
1444- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1445 how long the test file should take to play. Now accepts taking 2.93 secs
1446 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1447
Georg Brandl4793aa32006-07-28 18:31:39 +00001448- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1449 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1450 run via ``regrtest.py``. Now they do.

1459
1460- PythonLauncher now works correctly when the path to the script contains
1461 characters that are treated specially by the shell (such as quotes).
1462
1463- Bug #1527397: PythonLauncher now launches scripts with the working directory
1464 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001465 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001466 expect.

1474Core and builtins
1475-----------------
1476
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001477- Bug #1441486: The literal representation of -(sys.maxint - 1)
1478 again evaluates to a int object, not a long.
1479
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001480- Bug #1501934: The scope of global variables that are locally assigned
1481 using augmented assignment is now correctly determined.
1482
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001483- Bug #927248: Recursive method-wrapper objects can now safely
1484 be released.
1485
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001486- Bug #1417699: Reject locale-specific decimal point in float()
1487 and atof().
1488
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001489- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1490 omit a default "error" argument for NULL pointer. This allows
1491 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001492
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001493- Bug #1519018: 'as' is now validated properly in import statements.
1494
Neal Norwitz28746ab2006-07-09 22:14:42 +00001495- On 64 bit systems, int literals that use less than 64 bits are
1496 now ints rather than longs.
1497
Neal Norwitzed657552006-07-10 00:04:44 +00001498- Bug #1512814, Fix incorrect lineno's when code at module scope
1499 started after line 256.
1500
Tim Peters32a83612006-07-10 21:08:24 +00001501- New function ``sys._current_frames()`` returns a dict mapping thread
1502 id to topmost thread stack frame. This is for expert use, and is
1503 especially useful for debugging application deadlocks. The functionality
1504 was previously available in Fazal Majid's ``threadframe`` extension
1505 module, but it wasn't possible to do this in a wholly threadsafe way from
1506 an extension.

1509-------
1510
Martin v. Löwis77621582006-07-30 13:27:31 +00001511- Bug #1257728: Mention Cygwin in distutils error message about a missing
1512 VS 2003.
1513
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001514- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1515
Tim Peters32a83612006-07-10 21:08:24 +00001516- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001517 environment variable to be set in order to the SDK environment
1518 for finding the compiler, include files, etc.
1519
Martin v. Löwis388a8c22006-07-06 19:28:03 +00001520- Bug #1515998: Properly generate logical ids for files in bdist_msi.
1521
Nick Coghlan2d792252006-07-06 13:47:18 +00001522- warnings.py now ignores ImportWarning by default
1523
Thomas Woutersadd19112006-07-05 11:03:49 +00001524- string.Template() now correctly handles tuple-values. Previously,
1525 multi-value tuples would raise an exception and single-value tuples would
1526 be treated as the value they contain, instead.
1527
Martin v. Löwisede77f52006-07-03 13:01:35 +00001528- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1529 even if some data are received.
1530
Martin v. Löwis45482392006-07-03 12:28:58 +00001531- Bug #1267547: Put proper recursive setup.py call into the
1532 spec file generated by bdist_rpm.
1533
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001534- Bug #1514693: Update turtle's heading when switching between
1535 degrees and radians.
1536
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001537- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001538 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001539
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001540- Bug #1514703: Only setup canvas window in turtle when the canvas
1541 is created.
1542
Martin v. Löwis7596e832006-07-01 15:33:37 +00001543- Bug #1513223: .close() of a _socketobj now releases the underlying
1544 socket again, which then gets closed as it becomes unreferenced.
1545

1547 attribute values.
1548
1549- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1550 sgmllib ('[' and ']' were not accepted).
1551
Georg Brandl1be63af2006-06-28 20:23:25 +00001552- Fix a bug in the turtle module's end_fill function.
1553
Brett Cannon53ab5b72006-06-22 16:49:14 +00001554- Bug #1510580: The 'warnings' module improperly required that a Warning
1555 category be either a types.ClassType and a subclass of Warning. The proper
1556 check is just that it is a subclass with Warning as the documentation states.
1557
Georg Brandlad29e632006-06-21 17:45:17 +00001558- The compiler module now correctly compiles the new try-except-finally
1559 statement (bug #1509132).
1560
Neal Norwitz60373cd2006-06-22 06:30:50 +00001561- The wsgiref package is now installed properly on Unix.
1562
Vinay Sajip28e57612006-07-01 10:45:20 +00001563- A bug was fixed in logging.config.fileConfig() which caused a crash on
1564 shutdown when fileConfig() was called multiple times.
1565
Gerhard Häring762fbd32006-07-02 17:48:30 +00001566- The sqlite3 module did cut off data from the SQLite database at the first
1567 null character before sending it to a custom converter. This has been fixed
1568 now.
1569
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001570Extension Modules
1571-----------------
1572
Tim Peters112aad32006-07-19 00:03:19 +00001573- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1574 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1575 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001576
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001577- Assigning None to pointer type fields in ctypes structures possible
1578 overwrote the wrong fields, this is fixed now.
1579
1580- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1581 on non-Windows platforms.
1582
1583- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1584 integer or long, without range checking.
1585
1586- Patch #1517790: It is now possible to use custom objects in the ctypes
1587 foreign function argtypes sequence as long as they provide a from_param
1588 method, no longer is it required that the object is a ctypes type.
1589
1590- The '_ctypes' extension module now works when Python is configured
1591 with the --without-threads option.
1592
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001593- Bug #1513646: os.access on Windows now correctly determines write
1594 access, again.
1595
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001596- Bug #1512695: cPickle.loads could crash if it was interrupted with
1597 a KeyboardInterrupt.
1598
Neal Norwitza12aa882006-07-06 06:45:08 +00001599- Bug #1296433: parsing XML with a non-default encoding and
1600 a CharacterDataHandler could crash the interpreter in pyexpat.
1601
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001602- Patch #1516912: improve Modules support for OpenVMS.
1603
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001604Build
1605-----
1606
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001607- Automate Windows build process for the Win64 SSL module.
1608
Tim Peters32a83612006-07-10 21:08:24 +00001609- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001610 Previously, the slight difference could cause compilation errors of the
1611 'zlib' module on systems with more than one version of zlib.
1612
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001613- The MSI compileall step was fixed to also support a TARGETDIR
1614 with spaces in it.
1615
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001616- Bug #1517388: sqlite3.dll is now installed on Windows independent
1617 of Tcl/Tk.
1618
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001619- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001620 trying to be installed even though it's empty.
Georg Brandlad29e632006-06-21 17:45:17 +00001621
Neal Norwitzb15ac312006-06-29 04:10:08 +00001622Tests
1623-----
1624
1625- Call os.waitpid() at the end of tests that spawn child processes in order
1626 to minimize resources (zombies).
1627
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001628Documentation
1629-------------
1630
Nick Coghlan2d792252006-07-06 13:47:18 +00001631- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1632 documentation for the warnings module.
1633
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001634- Patch #1509163: MS Toolkit Compiler no longer available.
1635
Neal Norwitz56640df2006-07-10 02:36:41 +00001636- Patch #1504046: Add documentation for xml.etree.

1644Core and builtins
1645-----------------
1646
Georg Brandla56b9152006-06-19 06:35:54 +00001647- Patch #1507676: Error messages returned by invalid abstract object operations
1648 (such as iterating over an integer) have been improved and now include the
1649 type of the offending object to help with debugging.
1650
Brett Cannonea3912b2006-06-13 21:46:41 +00001651- Bug #992017: A classic class that defined a __coerce__() method that returned
1652 its arguments swapped would infinitely recurse and segfault the interpreter.
1653
Neal Norwitz909eb122006-06-12 02:13:21 +00001654- Fix the socket tests so they can be run concurrently.
1655
Neal Norwitzb9845e72006-06-12 02:11:18 +00001656- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001657 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001658
Brett Cannon22565aa2006-06-09 22:31:23 +00001659- Bug #532646: object.__call__() will continue looking for the __call__
1660 attribute on objects until one without one is found. This leads to recursion
1661 when you take a class and set its __call__ attribute to an instance of the
1662 class. Originally fixed for classic classes, but this fix is for new-style.
1663 Removes the infinite_rec_3 crasher.
1664
Georg Brandl24250812006-06-09 18:45:48 +00001665- The string and unicode methods startswith() and endswith() now accept
1666 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1667
Brett Cannonde3b0522006-06-08 17:00:45 +00001668- Buffer objects, at the C level, never used the char buffer
1669 implementation even when the char buffer for the wrapped object was
1670 explicitly requested (originally returned the read or write buffer).
1671 Now a TypeError is raised if the char buffer is not present but is
1672 requested.
1673
Georg Brandlddbaa662006-06-04 21:56:52 +00001674- Patch #1346214: Statements like "if 0: suite" are now again optimized
1675 away like they were in Python 2.4.
1676
Georg Brandlb7c8f542006-05-27 12:30:25 +00001677- Builtin exceptions are now full-blown new-style classes instead of
1678 instances pretending to be classes, which speeds up exception handling
1679 by about 80% in comparison to 2.5a2.
1680
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001681- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1682 Unicode 4.1.
1683
Georg Brandlf4ef1162006-05-26 18:03:31 +00001684- Patch #921466: sys.path_importer_cache is now used to cache valid and
1685 invalid file paths for the built-in import machinery which leads to
1686 fewer open calls on startup.
1687
Tim Peters696cf432006-05-24 21:10:40 +00001688- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1689 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1690 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1691 the number of input digits (it was and remains linear-time for bases
1692 2, 4, 8, 16 and 32).
1693
Tim Petersb713ec22006-05-23 18:45:30 +00001694- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1695 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1696 an integer close to ``sys.maxint``. This was repaired by patch
1697 #1335972, which also gives a nice speedup.
1698
Richard Jonescebbefc2006-05-23 18:28:17 +00001699- Patch #1337051: reduced size of frame objects.
1700
1701- PyErr_NewException now accepts a tuple of base classes as its
1702 "base" parameter.
1703
Richard Jones7c88dcc2006-05-23 10:37:38 +00001704- Patch #876206: function call speedup by retaining allocated frame
1705 objects.
1706
Georg Brandl7b90e162006-05-18 07:01:27 +00001707- Bug #1462152: file() now checks more thoroughly for invalid mode
1708 strings and removes a possible "U" before passing the mode to the
1709 C library function.
1710
Neal Norwitz1004a532006-05-15 07:17:23 +00001711- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1712
Neal Norwitz373f0a72006-05-15 07:04:36 +00001713- Bug #1487966: Fix SystemError with conditional expression in assignment
1714
Martin v. Löwis879768d2006-05-11 13:28:43 +00001715- WindowsError now has two error code attributes: errno, which carries
1716 the error values from errno.h, and winerror, which carries the error
1717 values from winerror.h. Previous versions put the winerror.h values
1718 (from GetLastError()) into the errno attribute.
1719
Martin v. Löwis77736712006-05-04 05:51:03 +00001720- Patch #1475845: Raise IndentationError for unexpected indent.
1721
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001722- Patch #1479181: split open() and file() from being aliases for each other.
1723
Tim Peters44bd9862006-06-01 13:49:23 +00001724- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1725 methods were always silently ignored by dictionaries when comparing keys.
1726 They are now passed through (except when using the C API function
1727 ``PyDict_GetItem()``, whose semantics did not change).
1728
1729- Bug #1456209: In some obscure cases it was possible for a class with a
1730 custom ``__eq__()`` method to confuse dict internals when class instances
1731 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1732 No, you don't have any code that did this ;-)

1735-----------------
1736
Trent Mick960a3f82006-06-28 20:30:41 +00001737- Bug #1295808: expat symbols should be namespaced in pyexpat
1738
1739- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1740
Brett Cannon6ee7d012006-06-08 16:23:04 +00001741- Change binascii.hexlify to accept a read-only buffer instead of only a char
1742 buffer and actually follow its documentation.
1743
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001744- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1745
Nick Coghlanc649ec52006-05-29 12:43:05 +00001746- Patch #1478788 (modified version): The functional extension module has
1747 been renamed to _functools and a functools Python wrapper module added.
1748 This provides a home for additional function related utilities that are
1749 not specifically about functional programming. See PEP 309.
1750
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001751- Patch #1493701: performance enhancements for struct module.
1752
Georg Brandl378d5922006-05-17 14:26:50 +00001753- Patch #1490224: time.altzone is now set correctly on Cygwin.
1754
Georg Brandl8d3342b2006-05-16 07:38:27 +00001755- Patch #1435422: zlib's compress and decompress objects now have a
1756 copy() method.
1757
Andrew MacIntyre92913322006-06-13 15:04:24 +00001758- Patch #1454481: thread stack size is now tunable at runtime for thread
1759 enabled builds on Windows and systems with Posix threads support.
1760
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001761- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1762 (up to the system limit of 32K characters).
1763
1764- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1765 As a result, these functions now raise WindowsError instead of OSError.
1766
Tim Peters7a822da2006-05-25 21:50:17 +00001767- ``time.clock()`` on Win64 should use the high-performance Windows
1768 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1769 Windows platforms).
1770
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001771- Calling Tk_Init twice is refused if the first call failed as that
1772 may deadlock.
1773
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001774- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1775 accept it without potentially using an uninitialized pointer.
1776
1777- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1778 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

1783
Gregory P. Smith372b5832006-06-05 18:48:21 +00001784- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1785 parameter is supplied. [SF pybsddb bug #1477863]
1786
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001787- bsddb: the __len__ method of a DB object has been fixed to return correct
1788 results. It could previously incorrectly return 0 in some cases.
1789 Fixes SF bug 1493322 (pybsddb bug 1184012).
1790
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001791- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1792 aborts the db transaction safely when a modifier callback fails.
1793 Fixes SF python patch/bug #1408584.
1794
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001795- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001796 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001797 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1798 database calls that would previously deadlock. [SF python bug #775414]

1829
Tim Peters43898b42006-06-14 04:09:25 +00001830- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1831 guarantee that adjacent triples in the return list always describe
1832 non-adjacent blocks. Previously, a pair of matching blocks could end
1833 up being described by multiple adjacent triples that formed a partition
1834 of the matching pair.

1843
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001844- The wsgiref package has been added to the standard library.
1845
Nick Coghlan676725d2006-06-08 13:54:49 +00001846- The functions update_wrapper() and wraps() have been added to the functools
1847 module. These make it easier to copy relevant metadata from the original
1848 function when writing wrapper functions.
1849
Tim Petersd6a9eef2006-06-05 01:48:21 +00001850- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1851 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001852
Martin v. Löwis3f767792006-06-04 19:36:28 +00001853- Patch #1359618: Speed up charmap encoder by using a trie structure
1854 for lookup.
1855
Tim Petersd609b1a2006-06-02 23:22:51 +00001856- The functions in the ``pprint`` module now sort dictionaries by key
1857 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1858 if and only if its display required more than one line, although that
1859 wasn't documented. The new behavior increases predictability; e.g.,
1860 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1861
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001862- Patch #1497027: try HTTP digest auth before basic auth in urllib2

Georg Brandlb89316f2006-05-17 15:51:16 +00001872- Patch #1180296: Two new functions were added to the locale module:
1873 format_string() to get the effect of "format % items" but locale-aware,
1874 and currency() to format a monetary number with currency sign.

1883 stdout arguments, making it possible to redirect input and output
1884 for remote debugging.
1885

1887 a couple of issues, notably handling of long file names using the
1888 GNU LONGNAME extension.
1889
1890- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1891 new flag when ``name`` is already the name of an option flag.
1892
1893- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1894 package.
1895

1938-----------------
1939
Thomas Heller1b046642006-04-18 18:51:06 +00001940- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1941 by converting these apis from macros into exported functions again:
1942
1943 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1944 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1945 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne

1947 PyRun_String Py_CompileString
1948
Martin v. Löwis45294a92006-04-18 06:24:08 +00001949- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1950
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001951- All uses of PyStructSequence_InitType have been changed to initialize
1952 the type objects only once, even if the interpreter is initialized
1953 multiple times.
1954
Neal Norwitz61546162006-04-14 05:20:28 +00001955- Bug #1454485, array.array('u') could crash the interpreter. This was
1956 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1957 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1958
1959- Py_UNICODE is unsigned. It was always documented as unsigned, but
1960 due to a bug had a signed value in previous versions.
1961
Tim Peters3a5e8b12006-04-11 01:44:07 +00001962- Patch #837242: ``id()`` of any Python object always gives a positive
1963 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1964 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001965 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001966 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001967
Tim Peters3a5e8b12006-04-11 01:44:07 +00001968 def __hash__(self):
1969 return id(self) # WRONG
1970
1971 because a hash result must be a (short) Python int but it was always
1972 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001973 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001974 was always usable as a hash value before this patch. That's no longer
1975 necessarily so.
1976
1977- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001978 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001979 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001980 #1454844)
1981
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001982- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1983 involving generators that have paused outside of any ``try`` or ``with``
1984 blocks. (In 2.5a1, a paused generator that was part of a reference
1985 cycle could not be garbage collected, regardless of whether it was
1986 paused in a ``try`` or ``with`` block.)

Tim Peters711bf302006-04-25 03:31:36 +00002018- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2019 a doctest to be skipped (the code is not run, and the expected output
2020 or exception is ignored).
2021
Nick Coghlanda2268f2006-04-24 04:37:15 +00002022- Fixed contextlib.nested to cope with exceptions being raised and
2023 caught inside exit handlers.
2024
Greg Wardab05edc2006-04-23 03:47:58 +00002025- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2026 hex, octal, or binary; add ``append_const`` action; keep going if
2027 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2028 added ``epilog`` for better help generation).
2029
Tim Peters21fbd572006-04-21 21:18:10 +00002030- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2031 called from a thread spawned as a side effect of importing a module.
2032
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002033- The pydoc module now supports documenting packages contained in
2034 .zip or .egg files.
2035
2036- The pkgutil module now has several new utility functions, such
2037 as ``walk_packages()`` to support working with packages that are either
2038 in the filesystem or zip files.
2039
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002040- The mailbox module can now modify and delete messages from
2041 mailboxes, in addition to simply reading them. Thanks to Gregory
2042 K. Johnson for writing the code, and to the 2005 Google Summer of
2043 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002044
Tim Petersc7605f22006-04-17 21:12:33 +00002045- The ``__del__`` method of class ``local`` in module ``_threading_local``
2046 returned before accomplishing any of its intended cleanup.
2047
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002048- Patch #790710: Add breakpoint command lists in pdb.

2078
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00002079- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002080
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002081- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2082 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002083 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002084 CXX from --with-cxx-main, see description in README.
2085
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002086- Patch #1429775: Link extension modules with the shared libpython.
2087
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002088- Fixed a libffi build problem on MIPS systems.
2089
Tim Peters8931ff12006-05-13 23:28:20 +00002090- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2091 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2092 and "%zu" for unsigned integers of type ``size_t``.
2093
Anthony Baxter51bcb682006-04-05 14:51:42 +00002094Tests
2095-----
2096
Nick Coghlanda2268f2006-04-24 04:37:15 +00002097- test_contextlib now checks contextlib.nested can cope with exceptions
2098 being raised and caught inside exit handlers.
2099
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002100- test_cmd_line now checks operation of the -m and -c command switches
2101
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002102- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2103 it separately and by hand. It also wasn't cleaning up its changes to
2104 the current Decimal context.
2105
Thomas Woutersabd08882006-04-26 15:53:30 +00002106- regrtest.py now has a -M option to run tests that test the new limits of
2107 containers, on 64-bit architectures. Running these tests is only sensible
2108 on 64-bit machines with more than two gigabytes of memory. The argument
2109 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +00002117Documentation
2118-------------
2119
Tim Petersb06d28c2006-05-12 01:57:59 +00002120- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2121
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002122- PEP 343: Added Context Types section to the library reference
2123 and attempted to bring other PEP 343 related documentation into
2124 line with the implementation and/or python-dev discussions.
2125
Tim Peters8dc73d22006-04-24 02:03:16 +00002126- Bug #1337990: clarified that ``doctest`` does not support examples
2127 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002130What's New in Python 2.5 alpha 1?
2131=================================
2132
Anthony Baxterebed3f62006-04-03 15:03:44 +00002133*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002134
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002135Core and builtins
2136-----------------
2137
Nick Coghlan43832302006-04-23 17:04:07 +00002138- PEP 338: -m command line switch now delegates to runpy.run_module
2139 allowing it to support modules in packages and zipfiles
2140
Martin v. Löwisc661b882006-04-20 04:54:23 +00002141- On Windows, .DLL is not an accepted file name extension for
2142 extension modules anymore; extensions are only found if they
2143 end in .PYD.
2144
Martin v. Löwisea62d252006-04-03 10:56:49 +00002145- Bug #1421664: sys.stderr.encoding is now set to the same value as
2146 sys.stdout.encoding.
2147
Neal Norwitz92e212f2006-04-03 04:48:37 +00002148- __import__ accepts keyword arguments.
2149
Georg Brandlccadf842006-03-31 18:54:53 +00002150- Patch #1460496: round() now accepts keyword arguments.
2151
Anthony Baxter262c00a2006-03-30 10:53:17 +00002152- Fixed bug #1459029 - unicode reprs were double-escaped.
2153
Hye-Shik Changd478f342006-03-23 12:32:36 +00002154- Patch #1396919: The system scope threads are reenabled on FreeBSD
2155 5.4 and later versions.
2156
Neal Norwitze98ccf62006-03-23 05:39:47 +00002157- Bug #1115379: Compiling a Unicode string with an encoding declaration
2158 now gives a SyntaxError.
2159
Georg Brandlabd1ff82006-03-18 07:59:59 +00002160- Previously, Python code had no easy way to access the contents of a
2161 cell object. Now, a ``cell_contents`` attribute has been added
2162 (closes patch #1170323).
2163
Tim Peterscf79aac2006-03-16 01:14:46 +00002164- Patch #1123430: Python's small-object allocator now returns an arena to
2165 the system ``free()`` when all memory within an arena becomes unused
2166 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2167 freed. Some applications will see a drop in virtual memory size now,
2168 especially long-running applications that, from time to time, temporarily
2169 use a large number of small objects. Note that when Python returns an
2170 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002171 platform C library will in turn return that memory to the operating system.
2172 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002173 appears to be effective at least on Microsoft C and gcc-based systems.
2174 Thanks to Evan Jones for hard work and patience.
2175
Georg Brandl533ff6f2006-03-08 18:09:27 +00002176- Patch #1434038: property() now uses the getter's docstring if there is
2177 no "doc" argument given. This makes it possible to legitimately use
2178 property() as a decorator to produce a read-only property.
2179
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002180- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2181 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2182 of requiring an int or long in slicing and a few other contexts, enabling
2183 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2184
Neal Norwitz995acdf2006-03-07 05:01:00 +00002185- Fixed various bugs reported by Coverity's Prevent tool.
2186
Brett Cannonbf364092006-03-01 04:25:17 +00002187- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2188 new exception base class, BaseException, which has a new message attribute.
2189 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2190 Raising a string exception now raises a DeprecationWarning.
2191
Thomas Woutersfb609f42006-02-28 16:37:25 +00002192- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2193 explicitly relative, using 'from .module import name' to mean 'from the same
2194 package as this module is in. Imports without dots still default to the
2195 old relative-then-absolute, unless 'from __future__ import
2196 absolute_import' is used.
2197
Brett Cannona7446e32006-02-27 23:39:10 +00002198- Properly check if 'warnings' raises an exception (usually when a filter set
2199 to "error" is triggered) when raising a warning for raising string
2200 exceptions.
2201
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002202- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002203 The name was removed from Include/code.h.
2204
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002205- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002206
Guido van Rossum1968ad32006-02-25 22:38:04 +00002207- Patch 1433928:
2208 - The copy module now "copies" function objects (as atomic objects).
2209 - dict.__getitem__ now looks for a __missing__ hook before raising
2210 KeyError.
2211
Tim Peters84ef21c2006-02-28 20:39:06 +00002212- PEP 343: with statement implemented. Needs ``from __future__ import
2213 with_statement``. Use of 'with' as a variable will generate a warning.
2214 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002215 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002216 The following objects have __context__ methods:
2217 - The built-in file type.
2218 - The thread.LockType type.
2219 - The following types defined by the threading module:
2220 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2221 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002222
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002223- Fix the encodings package codec search function to only search
2224 inside its own package. Fixes problem reported in patch #1433198.
2225
2226 Note: Codec packages should implement and register their own
2227 codec search function. PEP 100 has the details.
2228
Tim Peters9ea89d22006-06-04 03:26:02 +00002229- PEP 353: Using ``Py_ssize_t`` as the index type.
2230
2231- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2232 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2233 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2234 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2235 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002236
Neal Norwitzfc76d632006-01-10 06:03:13 +00002237- Patch #1400181, fix unicode string formatting to not use the locale.
2238 This is how string objects work. u'%f' could use , instead of .
2239 for the decimal point. Now both strings and unicode always use periods.
2240
Neal Norwitz671b9e32006-01-09 07:07:12 +00002241- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2242 configure would break checking curses.h.
2243
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002244- Bug #959576: The pwd module is now builtin. This allows Python to be
2245 built on UNIX platforms without $HOME set.
2246
Neal Norwitzc10978f2005-12-19 06:07:16 +00002247- Bug #1072182, fix some potential problems if characters are signed.
2248
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002249- Bug #889500, fix line number on SyntaxWarning for global declarations.
2250
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002251- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2252
Neal Norwitze7214a12005-12-18 05:03:17 +00002253- Support for converting hex strings to floats no longer works.
2254 This was not portable. float('0x3') now raises a ValueError.
2255
Barry Warsaw2a38a862005-12-18 01:27:35 +00002256- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002257 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002258 is now displayed in interactive prompt banner.
2259
Georg Brandlfa166682005-12-17 21:45:17 +00002260- Implementation of PEP 341 - Unification of try/except and try/finally.
2261 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002262 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002263
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002264- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2265 now encodes backslash correctly.
2266
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002267- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2268
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002269- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002270 and long longs.
2271
Neal Norwitz67715f02005-11-09 06:59:35 +00002272- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002273 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002274 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002275
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002276- Replaced most Unicode charmap codecs with new ones using the
2277 new Unicode translate string feature in the builtin charmap
2278 codec; the codecs were created from the mapping tables available
2279 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2280 encodings now include a mapping for the Apple logo)
2281
Tim Peterse3547fd2005-12-16 23:13:57 +00002282- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002283
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002284- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002285
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002286- A new AST parser implementation was completed. The abstract
2287 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002288 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002289
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002290- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002291 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2292
Neal Norwitz708e51a2005-10-03 04:48:15 +00002293- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2294
Neal Norwitz11bd1192005-10-03 00:54:56 +00002295- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2296 Provide a warning when a directory is passed on the command line.
2297
Neal Norwitz40d37812005-10-02 01:48:49 +00002298- Fix segfault with invalid coding.
2299
2300- SF bug #772896: unknown encoding results in MemoryError.
2301
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002302- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002303 supported a __len__() method which evaluated to False when the iterator
2304 was empty.
2305
Guido van Rossum630db602005-09-20 18:49:54 +00002306- On 64-bit platforms, when __len__() returns a value that cannot be
2307 represented as a C int, raise OverflowError.
2308
Skip Montanarof8948ca2005-09-19 03:54:46 +00002309- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002310 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002311
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002312- SF bug #893549: parsing keyword arguments was broken with a few format
2313 codes.
2314
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002315- Changes donated by Elemental Security to make it work on AIX 5.3
2316 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2317 bug #105470: test_pwd fails on 64bit system (Opteron).
2318
Guido van Rossum539c6622005-09-14 17:49:54 +00002319- Changes donated by Elemental Security to make it work on HP-UX 11 on
2320 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2321
Georg Brandl4550b8d2005-08-26 06:43:52 +00002322- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002323 (fixes bug #1119418).
2324
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002325- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2326
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002327- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2328 exceptions that cause a function to exit.
2329
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002330- The implementation of set() and frozenset() was revised to use its
2331 own internal data structure. Memory consumption is reduced by 1/3
2332 and there are modest speed-ups as well. The API is unchanged.
2333
Tim Petersde7990b2005-07-17 23:45:23 +00002334- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2335
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002336- SF bug #1229429: PyObject_CallMethod failed to decrement some
2337 reference counts in some error exit cases.
2338
Tim Petersecc6e6a2005-07-10 22:30:55 +00002339- SF bug #1185883: Python's small-object memory allocator took over
2340 a block managed by the platform C library whenever a realloc specified
2341 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002342 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002343 portable way to copy data from the C-managed block into Python's
2344 small-object space without risking a memory fault. Python's small-object
2345 realloc now leaves such blocks under the control of the platform C
2346 realloc.

Michael W. Hudsonb8963812005-07-05 15:21:58 +00002348- SF bug #1232517: An overflow error was not detected properly when
2349 attempting to convert a large float to an int in os.utime().
2350
Raymond Hettinger3296e692005-06-29 23:29:56 +00002351- SF bug #1224347: hex longs now print with lowercase letters just
2352 like their int counterparts.
2353
Michael W. Hudson188d4362005-06-20 16:52:57 +00002354- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2355 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2356 interpreter states; back out that fix and do a better job (see
2357 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2358 for a longer write-up of the problem).
2359
Michael W. Hudsondf888462005-06-03 14:41:55 +00002360- SF patch #1180995: marshal now uses a binary format by default when
2361 serializing floats.
2362
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002363- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2364 the routines that promise to produce IEEE 754 binary representations
2365 of floats now simply copy bytes around.
2366
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002367- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2368 278.
2369
Brett Cannonc3647ac2005-04-26 03:45:26 +00002370- patch #1109424: int, long, float, complex, and unicode now check for the
2371 proper magic slot for type conversions when subclassed. Previously the
2372 magic slot was ignored during conversion. Semantics now match the way
2373 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002374 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002375 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002376 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002377
Barry Warsawc8d907c2005-04-19 23:43:40 +00002378- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2379 NULL, now raise an AttributeError when attempting to set or delete the
2380 attribute. Previously a TypeError was raised, but this was inconsistent
2381 with the equivalent pure-Python implementation.
2382
Michael W. Hudson774479c2005-04-18 08:46:17 +00002383- It is now safe to call PyGILState_Release() before
2384 PyEval_InitThreads() (note that if there is reason to believe there
2385 are multiple threads around you still must call PyEval_InitThreads()
2386 before using the Python API; this fix is for extension modules that
2387 have no way of knowing if Python is multi-threaded yet).
2388
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002389- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2390 disabled caused a crash.
2391
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002392- Bug #1165306: instancemethod_new allowed the creation of a method
2393 with im_class == im_self == NULL, which caused a crash when called.
2394
Tim Petersecc6e6a2005-07-10 22:30:55 +00002395- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002396 fixes the crash seen in bug #1165761
2397
Raymond Hettinger96229b12005-03-11 06:49:40 +00002398- Added two new builtins, any() and all().
2399
Brett Cannon409d8f22005-03-05 06:47:57 +00002400- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002401 (e.g., ``class C(): pass`` is no longer a syntax error).
2402 Patch #1176012 added support to the 'parser' module and 'compiler' package
2403 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002404
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002405- Patch #1115086: Support PY_LONGLONG in structmember.
2406
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002407- Bug #1155938: new style classes did not check that __init__() was
2408 returning None.
2409
Tim Petersecc6e6a2005-07-10 22:30:55 +00002410- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002411 ('\') with a specific error message.
2412
Martin v. Löwisff232d72005-03-03 09:24:38 +00002413- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2414
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002415- Bug #1124295: the __name__ attribute of file objects was
2416 inadvertently made inaccessible in restricted mode.
2417
Tim Petersecc6e6a2005-07-10 22:30:55 +00002418- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002419 an ferror() call.
2420
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002421- min() and max() now support key= arguments with the same meaning as in
2422 list.sort().
2423
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002424- The peephole optimizer now performs simple constant folding in expressions:
2425 (2+3) --> (5).
2426
Raymond Hettingera422c342005-01-11 03:03:27 +00002427- set and frozenset objects can now be marshalled. SF #1098985.
2428
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002429- Bug #1077106: Poor argument checking could cause memory corruption
2430 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002431
Jeremy Hyltonab630502005-02-04 18:44:06 +00002432- The parser did not complain about future statements in illegal
2433 positions. It once again reports a syntax error if a future
2434 statement occurs after anything other than a doc string.
2435
Neil Schemenauercf52c072005-08-12 17:34:58 +00002436- Change the %s format specifier for str objects so that it returns a
2437 unicode instance if the argument is not an instance of basestring and
2438 calling __str__ on the argument returns a unicode instance.
2439
Tim Petersf4e69282006-02-27 17:15:31 +00002440- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2441 current thread state when the auto-GIL-state machinery knows about
2442 it (since the thread state is being deleted, continuing to remember it
2443 can't help, but can hurt if another thread happens to get created with
2444 the same thread id).
2445
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002446Extension Modules

2463
2464- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2465
2466- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002467 is deprecated. The undocumented re.engine variable no longer exists.

2471
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002472- The unicodedata module was updated to the 4.1 version of the Unicode
2473 database. The 3.2 version is still available as unicodedata.db_3_2_0
2474 for applications that require this specific version (such as IDNA).
2475
Neal Norwitzb62c4332006-03-04 18:35:47 +00002476- The timing module is no longer built by default. It was deprecated

2497
Martin v. Löwis14694662006-02-03 12:54:16 +00002498- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2499 are reported, the limit on path name lengths is removed, and stat reports
2500 WindowsError now (instead of OSError).
2501

2577 the request code argument, which results in more C-like behaviour
2578 for large or negative values.
2579
Tim Petersecc6e6a2005-07-10 22:30:55 +00002580- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

2622
Raymond Hettingerb2594052004-12-05 09:25:51 +00002623- itertools.islice() now accepts None for the start and step arguments.

Tim Peters112aad32006-07-19 00:03:19 +00002635
Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002636- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2637 been renamed to have only a single underscore prefix. This was done to
2638 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002639
Nick Coghlan43832302006-04-23 17:04:07 +00002640- PEP 338: new module runpy defines a run_module function to support
2641 executing modules which provide access to source code or a code object
2642 via the PEP 302 import mechanisms.
2643
Anthony Baxter93f5b932006-04-03 08:05:07 +00002644- The email module's parsedate_tz function now sets the daylight savings

2652 in attribute values.
2653
Anthony Baxterc51ee692006-04-01 00:57:31 +00002654- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002655 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002656 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002657 module will not be built.
2658
Tim Petersc17976e2006-04-01 00:26:53 +00002659- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2660 aren't officially supported here, and trying to use them will probably
2661 raise an exception some day. But dicts have been allowed, and "mostly
2662 worked", so support for them won't go away without warning.
2663
Georg Brandl338ef7d2006-03-31 18:42:16 +00002664- Bug #1445068: getpass.getpass() can now be given an explicit stream
2665 argument to specify where to write the prompt.
2666
Georg Brandl22ec80b2006-03-31 18:25:44 +00002667- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2676 to make it easier to monitor when daemon threads have completed
2677 processing all enqueued tasks. Patch #1455676.
2678
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002679- popen2.Popen objects now preserve the command in a .cmd attribute.
2680
Thomas Hellerc61c0492006-03-22 10:09:27 +00002681- Added the ctypes ffi package.
2682
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002683- email 4.0 package now integrated. This is largely the same as the email 3.0
2684 package that was included in Python 2.3, except that PEP 8 module names are
2685 now used (e.g. mail.message instead of email.Message). The MIME classes
2686 have been moved to a subpackage (e.g. email.mime.text instead of
2687 email.MIMEText). The old names are still supported for now. Several
2688 deprecated Message methods have been removed and lots of bugs have been
2689 fixed. More details can be found in the email package documentation.
2690
Walter Dörwald40108c92006-03-27 08:15:44 +00002691- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2692 (a subclass of tuple) that provides incremental decoders and encoders
2693 (a way to use stateful codecs without the stream API). Python functions
2694 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2695 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2696 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002697
Walter Dörwald067db482006-03-15 22:17:27 +00002698- Patch #1359365: Calling next() on a closed StringIO.String object raises
2699 a ValueError instead of a StopIteration now (like file and cString.String do).
2700 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2701 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002702
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002703- A regrtest option -w was added to re-run failed tests in verbose mode.

2776 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2777 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2778 Ronald L. Rivest offered this advice for Python:
2779
2780 "The consensus of researchers in this area (at least as
2781 expressed at the NIST Hash Function Workshop 10/31/05),
2782 is that SHA-256 is a good choice for the time being, but
2783 that research should continue, and other alternatives may
2784 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002785
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002786- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandl5284b532005-06-26 22:54:58 +00002870
Georg Brandl2f210b62005-06-26 22:09:06 +00002871- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
2872
Georg Brandlfbff1bc2005-06-26 21:36:25 +00002873- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
2874 error messages.
2875
Georg Brandl379f99d2005-06-26 21:09:38 +00002876- Bug #1108948: Cookie.py produced invalid JavaScript code.
2877
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00002878- The tokenize module now detects and reports indentation errors.
2879 Bug #1224621.
2880
Raymond Hettinger68c04532005-06-10 11:05:19 +00002881- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002882 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002883 the generate_tokens() function now accepts a callable argument that
2884 terminates by raising StopIteration.
2885
Georg Brandl9166e1a2005-06-04 09:20:03 +00002886- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2887
Georg Brandl268e61c2005-06-03 14:28:50 +00002888- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2889 component of the path.
2890
Skip Montanaro174dd222005-05-14 20:54:16 +00002891- Patch #1120353: The xmlrpclib module provides better, more transparent,
2892 support for datetime.{datetime,date,time} objects. With use_datetime set
2893 to True, applications shouldn't have to fiddle with the DateTime wrapper
2894 class at all.
2895
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002896- distutils.commands.upload was added to support uploading distribution
2897 files to PyPI.
2898
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002899- distutils.commands.register now encodes the data as UTF-8 before posting
2900 them to PyPI.
2901
Raymond Hettinger267b8682005-03-27 10:47:39 +00002902- decimal operator and comparison methods now return NotImplemented
2903 instead of raising a TypeError when interacting with other types. This
2904 allows other classes to implement __radd__ style methods and have them
2905 work as expected.
2906
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002907- Bug #1163325: Decimal infinities failed to hash. Attempting to
2908 hash a NaN raised an InvalidOperation instead of a TypeError.
2909
Tim Petersecc6e6a2005-07-10 22:30:55 +00002910- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002911 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2912

2916 to build.
2917
Martin v. Löwis637431b2005-03-03 23:12:42 +00002918- Patch #1103407: Properly deal with tarfile iterators when untarring
2919 symbolic links on Windows.

2942
Raymond Hettingerbab41432005-02-05 01:31:19 +00002943- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2944
Guido van Rossumd0641422005-02-03 15:01:24 +00002945- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2946 disables recursive traversal through instance attributes, which can
2947 be exploited in various ways.
2948
Tim Peterse3547fd2005-12-16 23:13:57 +00002949- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002950 flags on the HTTP listening socket.
2951
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002952- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2953 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2954
Fred Drakefbdeaad2006-07-29 16:56:15 +00002955- Patches #893642, #1039083: add allow_none, encoding arguments to
2956 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002957
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002958- Bug #1110478: Revert os.environ.update to do putenv again.
2959
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002960- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2961
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002962- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2963
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002964- Enhancements to the csv module:
2965
2966 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002967 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002968 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002969 + Dialect parameter parsing has been re-implemented to improve error
2970 reporting.
2971 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2972 dictates.
2973 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002974 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002975 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002976 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2977 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002978 + reader now allows \r characters to be quoted (previously it only allowed
2979 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002980 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002981 + Dialect classes passed to the module are no longer instantiated by
2982 the module before being parsed (the former validation scheme required
2983 this, but the mechanism was unreliable).
2984 + The dialect registry now contains instances of the internal
2985 C-coded dialect type, rather than references to python objects.
2986 + the internal c-coded dialect type is now immutable.
2987 + register_dialect now accepts the same keyword dialect specifications
2988 as the reader and writer, allowing the user to register dialects
2989 without first creating a dialect class.
2990 + a configurable limit to the size of parsed fields has been added -
2991 previously, an unmatched quote character could result in the entire
2992 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002993 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002994 the parser field size limit (returning the former limit). The initial
2995 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002996 + A line_num attribute has been added to the reader object, which tracks
2997 the number of lines read from the source iterator. This is not
2998 the same as the number of records returned, as records can span
2999 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003000 + reader and writer objects were not being registered with the cyclic-GC.
3001 This has been fixed.
3002
Brett Cannone6539c42005-01-08 02:43:53 +00003003- _DummyThread objects in the threading module now delete self.__block that is
3004 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3005 lock primitives tend to be limited in number and thus should not be wasted on
3006 a _DummyThread object. Fixes bug #1089632.
3007
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003008- The imghdr module now detects Exif files.
3009
Raymond Hettinger6065d322004-12-20 23:51:53 +00003010- StringIO.truncate() now correctly adjusts the size attribute.
3011 (Bug #951915).
3012
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003013- locale.py now uses an updated locale alias table (built using
3014 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3015 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003016 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003017
Raymond Hettinger3557f422004-12-07 12:02:02 +00003018- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3019
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003020- the pickle module no longer accepts the deprecated None option in the
3021 args tuple returned by __reduce__().
3022
Brett Cannon84667c02004-12-07 03:25:18 +00003023- optparse now optionally imports gettext. This allows its use in setup.py.
3024
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003025- the pickle module no longer uses the deprecated bin parameter.
3026
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003027- the shelve module no longer uses the deprecated binary parameter.
3028
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003029- the pstats module no longer uses the deprecated ignore() method.
3030
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003031- the filecmp module no longer uses the deprecated use_statcache argument.
3032
Raymond Hettinger664347b2004-12-04 21:21:53 +00003033- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3034 extended or overridden by subclasses. Formerly, the subclassed method would
3035 be ignored by the rest of the module. (Bug #1078905).
3036
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003037- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003038 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003039
Walter Dörwald36733692004-12-22 12:50:50 +00003040- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3041 once when a size argument is given. This prevents a buffer overflow in the
3042 tokenizer with very long source lines.
3043
Barry Warsaw538561e2006-01-01 21:48:54 +00003044- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3045 immediately after creating the object, without any intervening
3046 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003047
Skip Montanaro05885812005-01-16 20:48:27 +00003048- The reconvert.quote function can now emit triple-quoted strings. The
3049 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003050
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003051- ``UserString.MutableString`` now supports negative indices in
3052 ``__setitem__`` and ``__delitem__``
3053
Greg Ward40407942005-03-05 02:53:17 +00003054- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3055 correctly.
3056
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003057- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3058 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3059 character even if the user has passed a size parameter to get a proper
3060 line ending. Remove the special handling of a "\r\n" that has been split
3061 between two lines.
3062
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003063- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3064 about illegal code points. The codec now supports PEP 293 style error
3065 handlers.
3066
Walter Dörwald78a78b02005-09-01 12:04:29 +00003067- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003068 from the input stream, so that the output is a byte string in the correct
3069 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003070
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003071- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3072 considering it exactly like a '*'.
3073
Walter Dörwald007f8df2005-10-09 19:42:27 +00003074- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3075 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003076
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003077- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3078
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003079- Patch #1413711: Certain patterns of differences were making difflib
3080 touch the recursion limit.
3081
Walter Dörwald58917a62006-03-31 15:26:22 +00003082- Bug #947906: An object oriented interface has been added to the calendar
3083 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003084 called as a script (e.g. via ``python -mcalendar``). Localized month and
3085 weekday names can be ouput (even if an exotic encoding is used) using
3086 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003087

Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003102- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3103 The zlib module is now builtin on Windows.
3104
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003105- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3106
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003107- Bug #1189330: configure did not correctly determine the necessary
3108 value of LINKCC if python was built with GCC 4.0.
3109
Trent Mick8321b422005-07-26 02:29:21 +00003110- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3111 vulnerability in zlib 1.2.1 and 1.2.2.
3112
Brett Cannon08cd5982005-04-24 22:26:38 +00003113- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3114 flags that change binary compatibility. Changes were also made to
3115 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003116 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003117
Bob Ippolitoed233462005-03-29 13:47:59 +00003118- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3119 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3120 no longer exists). This configure patch makes things right.
3121
Martin v. Löwise2713be2005-03-08 15:03:08 +00003122- Bug #1158607: Build with --disable-unicode again.
3123
Brett Cannon46d96232005-02-16 00:07:19 +00003124- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3125 defined. Discovered as a result of not being able to build on OS X.
3126
Brett Cannon516592f2004-12-07 00:42:59 +00003127- setup.py now uses the directories specified in LDFLAGS using the -L option
3128 and in CPPFLAGS using the -I option for adding library and include
3129 directories, respectively, for compiling extension modules against. This has
3130 led to the core being compiled using the values in CPPFLAGS. It also removes
3131 the need for the special-casing of both DarwinPorts and Fink for darwin since
3132 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3133 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3134 Fink, ``-I/opt/local/include`` for DarwinPorts).

Brett Cannon43802422005-02-10 20:48:03 +00003136- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3137 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3138 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3139 Closes bug #1096244. Thanks Gregory Bond.

Tim Petersc9d78aa2006-03-26 23:27:58 +00003144- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3145 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3146 is obtained via the ``PyObject_`` family, it must be released via the
3147 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3148 always been officially true, but when Python's small-object allocator was
3149 introduced, an attempt was made to cater to a few extension modules
3150 discovered at the time that obtained memory via ``PyObject_New`` but
3151 released it via ``PyMem_DEL``. It's years later, and if such code still
3152 exists it will fail now (probably with segfaults, but calling wrong
3153 low-level memory management functions can yield many symptoms).
3154
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003155- Added a C API for set and frozenset objects.

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003159- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3160 mapping argument now. This string is used as a mapping table. Byte values
3161 greater than the length of the string and 0xFFFE are treated as undefined
3162 mappings.
