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.

Amaury Forgeot d'Arc8d904c32008-04-22 21:17:18 +000051- Issue #2670: Fix a failure in urllib2.build_opener(), when passed two
52 handlers that derive the same default base class.
53
Amaury Forgeot d'Arc198e3532008-03-27 23:41:59 +000054- Issue #2495: tokenize.untokenize now inserts a space between two consecutive
55 string literals; previously, ["" ""] was rendered as [""""], which is
56 incorrect python code.
57
Mark Dickinsonbfdbfd42008-03-25 18:58:13 +000058- Issue #2482: Make sure that the coefficient of a Decimal is always
59 stored as a str instance, not as a unicode instance. This ensures
60 that str(Decimal) is always an instance of str. This fixes a
61 regression from Python 2.5.1 to Python 2.5.2.
62
Mark Dickinson26c25d92008-03-25 14:35:25 +000063- Issue #2478: fix failure of decimal.Decimal(0).sqrt()
64
Georg Brandld9b9d682008-03-21 20:01:55 +000065- Issue #2432: give DictReader the dialect and line_num attributes
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.
70

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().
81
Andrew M. Kuchling05a19a52008-02-23 17:21:44 +000082- Bug #1433694: minidom's .normalize() failed to set .nextSibling for
83 last child element.
84
Gregory P. Smith26660402008-06-01 23:44:46 +000085- Issue #2791: subprocess.Popen.communicate explicitly closes its
86 stdout and stderr fds rather than leaving them open until the
87 instance is destroyed.

94
Gregory P. Smith14acde32008-04-09 23:41:13 +000095- zlib.decompressobj().flush(value) no longer crashes the interpreter when
96 passed a value less than or equal to zero.
97
Gregory P. Smith0812de62008-05-17 06:46:39 +000098- issue2858: Fix potential memory corruption when bsddb.db.DBEnv.lock_get
99 and other bsddb.db object constructors raised an exception.

139-----------------
140
Martin v. Löwis73c01d42008-02-14 11:26:18 +0000141- Added checks for integer overflows, contributed by Google. Some are
142 only available if asserts are left in the code, in cases where they

968
Neal Norwitz0bcafac2006-09-11 08:51:17 +0000969- Make _PyGILState_NoteThreadState() static, it was not used anywhere
970 outside of pystate.c and should not be necessary.
971
Brett Cannon19d76c52006-09-09 07:18:44 +0000972- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
973 allows calling unicode() on exceptions classes directly to succeed.
974
Georg Brandlecab6232006-09-06 06:47:02 +0000975- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
976 Also make sure that every exception class has __module__ set to
977 'exceptions'.
978
Georg Brandl37a9e572006-09-06 06:09:34 +0000979- Bug #1550983: emit better error messages for erroneous relative

989
Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000990- The return tuple from str.rpartition(sep) is (tail, sep, head) where
991 head is the original string if sep was not found.
992
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000993- Bug #1520864: unpacking singleton tuples in list comprehensions and
994 generator expressions (x for x, in ... ) works again. Fixing this problem
995 required changing the .pyc magic number. This means that .pyc files
996 generated before 2.5c2 will be regenerated.

1110
Neal Norwitz24b6f202006-09-05 04:43:56 +00001111- Fix infinite recursion when subclassing long and overriding __hash__.
1112
1113- Fix concatenation (+=) of long strings.
1114
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001115- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001116 compared equal or unequal to a string and a UnicodeDecodeError
1117 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001118
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001119 Instead, the equal (==) and unequal (!=) comparison operators will
1120 now issue a UnicodeWarning and interpret the two objects as
1121 unequal. The UnicodeWarning can be filtered as desired using
1122 the warning framework, e.g. silenced completely, turned into an
1123 exception, logged, etc.
1124
1125 Note that compare operators other than equal and unequal will still
1126 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001127
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001128- Fix segfault when doing string formatting on subclasses of long.
1129
1130- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1131 with new-style classes.
1132
1133- Fix bug related to __len__ functions returning negative values with
1134 classic classes.
1135
1136- Patch #1538606, Fix __index__() clipping. There were some problems
1137 discovered with the API and how integers that didn't fit into Py_ssize_t
1138 were handled. This patch attempts to provide enough alternatives
1139 to effectively use __index__.
1140
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001141- Bug #1536021: __hash__ may now return long int; the final hash
1142 value is obtained by invoking hash on the long int.
1143
Thomas Hellerab1049c2006-08-08 17:37:00 +00001144- Bug #1536786: buffer comparison could emit a RuntimeWarning.

1147 sys.stdin is closed.
1148
Thomas Heller74d36f02006-08-04 18:17:40 +00001149- On Windows, the PyErr_Warn function is now exported from
1150 the Python dll again.
1151
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001152- Bug #1191458: tracing over for loops now produces a line event
1153 on each iteration. Fixing this problem required changing the .pyc
1154 magic number. This means that .pyc files generated before 2.5c1
1155 will be regenerated.
1156
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001157- Bug #1333982: string/number constants were inappropriately stored
1158 in the byte code and co_consts even if they were not used, ie
1159 immediately popped off the stack.
1160
Georg Brandle9462c72006-08-04 18:03:37 +00001161- Fixed a reference-counting problem in property().

1165-------
1166
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001167- Fix a bug in the ``compiler`` package that caused invalid code to be
1168 generated for generator expressions.
1169
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001170- The distutils version has been changed to 2.5.0. The change to
1171 keep it programmatically in sync with the Python version running
1172 the code (introduced in 2.5b3) has been reverted. It will continue
1173 to be maintained manually as static string literal.
1174
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001175- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001176 and this cannot be converted to the required C type, an exception is
1177 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001178 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001179
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001180- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001181 an exception.
1182
Tim Peterscbdd3502006-09-05 01:47:53 +00001183- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001184 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001185 workarounds for clocks with low resolution, to stop the code yielding
1186 duplicate UUIDs.
1187
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001188- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1189 before raising SystemExit, allowing IDLE to honor quit() and exit().
1190

1202 str(exception) raised an exception.
1203
Neil Schemenauer06ded092006-08-04 16:20:30 +00001204- Fix a bug in the ``compiler`` package that caused invalid code to be

1217
Thomas Heller1ce433e2006-08-14 16:20:04 +00001218- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1219 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1220
Thomas Heller86720042006-08-14 11:17:48 +00001221- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1222 uses the _as_parameter_ attribute when objects are passed to foreign
1223 function calls. The ctypes version number was changed to 1.0.1.
1224
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001225- Bug #1530559, struct.pack raises TypeError where it used to convert.
1226 Passing float arguments to struct.pack when integers are expected
1227 now triggers a DeprecationWarning.

1262-----
1263

1265
Tim Peters4643c2f2006-08-10 22:45:34 +00001266- Bug #1069160. Internal correctness changes were made to
1267 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1268 the documentation was changed to state that the return value
1269 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001272What's New in Python 2.5 beta 3?
1273================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001274
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001275*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001276
1277Core and builtins
1278-----------------
1279
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001280- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001281 returned a long (see PEP 353).
1282
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001283- Bug #1515471: string.replace() accepts character buffers again.
1284
Neal Norwitz07aadb12006-07-30 06:55:48 +00001285- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1286 This provides the proper warning for struct.pack().
1287 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1288
Neal Norwitz0d62a062006-07-30 06:53:31 +00001289- Patch #1531113: Fix augmented assignment with yield expressions.
1290 Also fix a SystemError when trying to assign to yield expressions.
1291
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001292- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1293 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1294 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1295 excessive filesystem operations during imports.
1296
Tim Petersbc24eee2006-07-27 01:14:53 +00001297- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1298 operations on signed longs that are formally undefined by C.
1299 Unfortunately, at least one compiler now cares about that, so complicated
1300 the code to make that compiler happy again.
1301
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001302- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1303
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001304- Patch #1232023: Stop including current directory in search
1305 path on Windows.
1306
Neal Norwitze1fdb322006-07-21 05:32:28 +00001307- Fix some potential crashes found with failmalloc.
1308
Neal Norwitze7563102006-07-17 01:00:16 +00001309- Fix warnings reported by Klocwork's static analysis tool.
1310
Neal Norwitz84be93b2006-07-16 01:50:38 +00001311- Bug #1512814, Fix incorrect lineno's when code within a function
1312 had more than 255 blank lines.
1313
Georg Brandl9dceedb2006-07-12 15:31:17 +00001314- Patch #1521179: Python now accepts the standard options ``--help`` and
1315 ``--version`` as well as ``/?`` on Windows.
1316
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001317- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001318 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001319 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001320
Tim Peters112aad32006-07-19 00:03:19 +00001321- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001322 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001323 new ``sys._current_frames()`` returns a dictionary with one entry,
1324 mapping the faux "thread id" 0 to the current frame.
1325
Ronald Oussoren3075e162006-07-25 20:28:55 +00001326- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001327
Ronald Oussoren3075e162006-07-25 20:28:55 +00001328
Neal Norwitza1f10902006-07-12 07:28:29 +00001329Library
1330-------
1331
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001332- Correction of patch #1455898: In the mbcs decoder, set final=False
1333 for stream decoder, but final=True for the decode function.
1334
Georg Brandl07fec3a2006-08-01 18:49:24 +00001335- os.urandom no longer masks unrelated exceptions like SystemExit or
1336 KeyboardInterrupt.
1337
Tim Peters4643c2f2006-08-10 22:45:34 +00001338- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001339 shutil.copytree on Windows
1340
Georg Brandle34ac7c2006-07-30 11:07:23 +00001341- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1342 refers to file descriptors, not file objects.
1343
Tim Peterscbdd3502006-09-05 01:47:53 +00001344- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001345 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001346 #1513611, and probably others.
1347
Georg Brandledd9b0d2006-07-29 09:33:26 +00001348- Bug #1441397: The compiler module now recognizes module and function
1349 docstrings correctly as it did in Python 2.4.
1350
Tim Peters6f681472006-07-27 23:44:37 +00001351- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1352 lost that tests are sorted by name before being run. This rarely
1353 matters for well-written tests, but can create baffling symptoms if
1354 side effects from one test to the next affect outcomes. ``DocTestFinder``
1355 has been changed to sort the list of tests it returns.
1356
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001357- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001358 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001359
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001360- Bug #978833: Really close underlying socket in _socketobject.close.
1361
Georg Brandldb232dc2006-08-20 13:15:43 +00001362- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1363 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001364
Georg Brandlcf0c1722006-07-26 07:23:32 +00001365- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1366 to recursive calls and call it with the failing package name.
1367
Martin v. Löwis0b483032006-07-25 09:53:12 +00001368- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1369
Georg Brandlc13c34c2006-07-24 14:09:56 +00001370- Patch #1515343: Fix printing of deprecated string exceptions with a
1371 value in the traceback module.
1372
Greg Ward48fae7a2006-07-23 16:05:51 +00001373- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1374
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001375- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1376
Brett Cannoncaebe222006-07-18 04:41:36 +00001377- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1378 argument tuple. For arguments where zero is illegal, the value is forced to
1379 the minimum value that is correct. This is to support an undocumented but
1380 common way people used to fill in inconsequential information in the time
1381 tuple pre-2.4.
1382
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001383- Patch #1220874: Update the binhex module for Mach-O.
1384
Barry Warsawb110bad2006-07-21 14:51:07 +00001385- The email package has improved RFC 2231 support, specifically for
1386 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1387 (name*0=<blah>) parameter continuations. This may change the types of
1388 values returned from email.message.Message.get_param() and friends.
1389 Specifically in some cases where non-encoded continuations were used,
1390 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1391 will just return the string (since non-encoded continuations don't have
1392 charset and language parts).
1393
1394 Also, whereas % values were decoded in all parameter continuations, they are
1395 now only decoded in encoded parameter parts.
1396
Ronald Oussoren3075e162006-07-25 20:28:55 +00001397- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1398
1399- Bug #1517996: IDLE now longer shows the default Tk menu when a
1400 path browser, class browser or debugger is the frontmost window on MacOS X
1401
Barry Warsaw00decd72006-07-27 23:43:15 +00001402- Patch #1520294: Support for getset and member descriptors in types.py,
1403 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1404 of an object against these built-in types and more importantly, for getting
1405 their docstrings printed in the interactive interpreter's help() function.

1410
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001411- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1412 a socket operation on a socket with a timeout, the exception will be
1413 caught correctly. Previously, the exception was not caught.
1414
Thomas Heller1393d6a2006-07-28 21:43:20 +00001415- Patch #1529514: The _ctypes extension is now compiled on more
1416 openbsd target platforms.
1417
Tim Peters9cab5932006-07-28 00:30:00 +00001418- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1419 a memory leak, affecting pickles and deep copies.
1420
Tim Petersbc24eee2006-07-27 01:14:53 +00001421- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1423
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001424- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1425
Thomas Hellerce049a02006-07-14 17:51:14 +00001426- Patch #1521817: Index range checking on ctypes arrays containing
1427 exactly one element enabled again. This allows iterating over these
1428 arrays, without the need to check the array size before.
1429
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001430- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001431 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001432 /dev/null in certain cases; this is now fixed.
1433
Thomas Heller47d7a062006-07-12 08:43:47 +00001434- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1435 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001436
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001437- Because of a misspelled preprocessor symbol, ctypes was always
1438 compiled without thread support; this is now fixed.
1439
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001440- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1441 methods now allow their database parameter to be None as the
1442 sleepycat API allows.
1443
Matt Flemingec926502006-07-28 11:27:27 +00001444- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1445 bluetooth API compared with Linux and FreeBSD.
1446
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001447Tests
1448-----
1449
1450- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1451 how long the test file should take to play. Now accepts taking 2.93 secs
1452 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1453
Georg Brandl4793aa32006-07-28 18:31:39 +00001454- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1455 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1456 run via ``regrtest.py``. Now they do.

1465
1466- PythonLauncher now works correctly when the path to the script contains
1467 characters that are treated specially by the shell (such as quotes).
1468
1469- Bug #1527397: PythonLauncher now launches scripts with the working directory
1470 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001471 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001472 expect.

1480Core and builtins
1481-----------------
1482
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001483- Bug #1441486: The literal representation of -(sys.maxint - 1)
1484 again evaluates to a int object, not a long.
1485
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001486- Bug #1501934: The scope of global variables that are locally assigned
1487 using augmented assignment is now correctly determined.
1488
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001489- Bug #927248: Recursive method-wrapper objects can now safely
1490 be released.
1491
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001492- Bug #1417699: Reject locale-specific decimal point in float()
1493 and atof().
1494
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001495- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1496 omit a default "error" argument for NULL pointer. This allows
1497 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001498
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001499- Bug #1519018: 'as' is now validated properly in import statements.
1500
Neal Norwitz28746ab2006-07-09 22:14:42 +00001501- On 64 bit systems, int literals that use less than 64 bits are
1502 now ints rather than longs.
1503
Neal Norwitzed657552006-07-10 00:04:44 +00001504- Bug #1512814, Fix incorrect lineno's when code at module scope
1505 started after line 256.
1506
Tim Peters32a83612006-07-10 21:08:24 +00001507- New function ``sys._current_frames()`` returns a dict mapping thread
1508 id to topmost thread stack frame. This is for expert use, and is
1509 especially useful for debugging application deadlocks. The functionality
1510 was previously available in Fazal Majid's ``threadframe`` extension
1511 module, but it wasn't possible to do this in a wholly threadsafe way from
1512 an extension.
1513

1515-------
1516
Martin v. Löwis77621582006-07-30 13:27:31 +00001517- Bug #1257728: Mention Cygwin in distutils error message about a missing
1518 VS 2003.
1519
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001520- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1521
Tim Peters32a83612006-07-10 21:08:24 +00001522- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001523 environment variable to be set in order to the SDK environment
1524 for finding the compiler, include files, etc.
1525
Martin v. Löwis388a8c22006-07-06 19:28:03 +00001526- Bug #1515998: Properly generate logical ids for files in bdist_msi.
1527
Nick Coghlan2d792252006-07-06 13:47:18 +00001528- warnings.py now ignores ImportWarning by default
1529
Thomas Woutersadd19112006-07-05 11:03:49 +00001530- string.Template() now correctly handles tuple-values. Previously,
1531 multi-value tuples would raise an exception and single-value tuples would
1532 be treated as the value they contain, instead.
1533
Martin v. Löwisede77f52006-07-03 13:01:35 +00001534- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1535 even if some data are received.
1536
Martin v. Löwis45482392006-07-03 12:28:58 +00001537- Bug #1267547: Put proper recursive setup.py call into the
1538 spec file generated by bdist_rpm.
1539
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001540- Bug #1514693: Update turtle's heading when switching between
1541 degrees and radians.
1542
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001543- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001544 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001545
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001546- Bug #1514703: Only setup canvas window in turtle when the canvas
1547 is created.
1548
Martin v. Löwis7596e832006-07-01 15:33:37 +00001549- Bug #1513223: .close() of a _socketobj now releases the underlying

1553 attribute values.
1554
1555- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1556 sgmllib ('[' and ']' were not accepted).
1557
Georg Brandl1be63af2006-06-28 20:23:25 +00001558- Fix a bug in the turtle module's end_fill function.
1559
Brett Cannon53ab5b72006-06-22 16:49:14 +00001560- Bug #1510580: The 'warnings' module improperly required that a Warning
1561 category be either a types.ClassType and a subclass of Warning. The proper
1562 check is just that it is a subclass with Warning as the documentation states.
1563
Georg Brandlad29e632006-06-21 17:45:17 +00001564- The compiler module now correctly compiles the new try-except-finally
1565 statement (bug #1509132).
1566
Neal Norwitz60373cd2006-06-22 06:30:50 +00001567- The wsgiref package is now installed properly on Unix.
1568
Vinay Sajip28e57612006-07-01 10:45:20 +00001569- A bug was fixed in logging.config.fileConfig() which caused a crash on
1570 shutdown when fileConfig() was called multiple times.
1571
Gerhard Häring762fbd32006-07-02 17:48:30 +00001572- The sqlite3 module did cut off data from the SQLite database at the first
1573 null character before sending it to a custom converter. This has been fixed
1574 now.
1575
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001576Extension Modules
1577-----------------
1578
Tim Peters112aad32006-07-19 00:03:19 +00001579- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1580 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1581 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001582
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001583- Assigning None to pointer type fields in ctypes structures possible
1584 overwrote the wrong fields, this is fixed now.
1585
1586- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1587 on non-Windows platforms.
1588
1589- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1590 integer or long, without range checking.
1591
1592- Patch #1517790: It is now possible to use custom objects in the ctypes
1593 foreign function argtypes sequence as long as they provide a from_param
1594 method, no longer is it required that the object is a ctypes type.
1595
1596- The '_ctypes' extension module now works when Python is configured
1597 with the --without-threads option.
1598
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001599- Bug #1513646: os.access on Windows now correctly determines write
1600 access, again.
1601
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001602- Bug #1512695: cPickle.loads could crash if it was interrupted with
1603 a KeyboardInterrupt.
1604
Neal Norwitza12aa882006-07-06 06:45:08 +00001605- Bug #1296433: parsing XML with a non-default encoding and
1606 a CharacterDataHandler could crash the interpreter in pyexpat.
1607
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001608- Patch #1516912: improve Modules support for OpenVMS.
1609
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001610Build
1611-----
1612
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001613- Automate Windows build process for the Win64 SSL module.
1614
Tim Peters32a83612006-07-10 21:08:24 +00001615- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001616 Previously, the slight difference could cause compilation errors of the
1617 'zlib' module on systems with more than one version of zlib.
1618
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001619- The MSI compileall step was fixed to also support a TARGETDIR
1620 with spaces in it.
1621
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001622- Bug #1517388: sqlite3.dll is now installed on Windows independent
1623 of Tcl/Tk.
1624
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001625- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001626 trying to be installed even though it's empty.
Georg Brandlad29e632006-06-21 17:45:17 +00001627
Neal Norwitzb15ac312006-06-29 04:10:08 +00001628Tests
1629-----
1630
1631- Call os.waitpid() at the end of tests that spawn child processes in order
1632 to minimize resources (zombies).
1633
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001634Documentation
1635-------------
1636
Nick Coghlan2d792252006-07-06 13:47:18 +00001637- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1638 documentation for the warnings module.
1639
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001640- Patch #1509163: MS Toolkit Compiler no longer available.
1641
Neal Norwitz56640df2006-07-10 02:36:41 +00001642- Patch #1504046: Add documentation for xml.etree.

Nick Coghlanc649ec52006-05-29 12:43:05 +00001645What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +00001646================================
Anthony Baxter51bcb682006-04-05 14:51:42 +00001647
Anthony Baxterd1136802006-06-19 12:04:15 +00001648*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +00001649
1650Core and builtins
1651-----------------
1652
Georg Brandla56b9152006-06-19 06:35:54 +00001653- Patch #1507676: Error messages returned by invalid abstract object operations
1654 (such as iterating over an integer) have been improved and now include the
1655 type of the offending object to help with debugging.
1656
Brett Cannonea3912b2006-06-13 21:46:41 +00001657- Bug #992017: A classic class that defined a __coerce__() method that returned
1658 its arguments swapped would infinitely recurse and segfault the interpreter.
1659
Neal Norwitz909eb122006-06-12 02:13:21 +00001660- Fix the socket tests so they can be run concurrently.
1661
Neal Norwitzb9845e72006-06-12 02:11:18 +00001662- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001663 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001664
Brett Cannon22565aa2006-06-09 22:31:23 +00001665- Bug #532646: object.__call__() will continue looking for the __call__
1666 attribute on objects until one without one is found. This leads to recursion
1667 when you take a class and set its __call__ attribute to an instance of the
1668 class. Originally fixed for classic classes, but this fix is for new-style.
1669 Removes the infinite_rec_3 crasher.
1670
Georg Brandl24250812006-06-09 18:45:48 +00001671- The string and unicode methods startswith() and endswith() now accept
1672 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1673
Brett Cannonde3b0522006-06-08 17:00:45 +00001674- Buffer objects, at the C level, never used the char buffer
1675 implementation even when the char buffer for the wrapped object was
1676 explicitly requested (originally returned the read or write buffer).
1677 Now a TypeError is raised if the char buffer is not present but is
1678 requested.
1679
Georg Brandlddbaa662006-06-04 21:56:52 +00001680- Patch #1346214: Statements like "if 0: suite" are now again optimized
1681 away like they were in Python 2.4.
1682
Georg Brandlb7c8f542006-05-27 12:30:25 +00001683- Builtin exceptions are now full-blown new-style classes instead of
1684 instances pretending to be classes, which speeds up exception handling
1685 by about 80% in comparison to 2.5a2.
1686
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001687- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1688 Unicode 4.1.
1689
Georg Brandlf4ef1162006-05-26 18:03:31 +00001690- Patch #921466: sys.path_importer_cache is now used to cache valid and
1691 invalid file paths for the built-in import machinery which leads to
1692 fewer open calls on startup.
1693
Tim Peters696cf432006-05-24 21:10:40 +00001694- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1695 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1696 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1697 the number of input digits (it was and remains linear-time for bases
1698 2, 4, 8, 16 and 32).
1699
Tim Petersb713ec22006-05-23 18:45:30 +00001700- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1701 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1702 an integer close to ``sys.maxint``. This was repaired by patch
1703 #1335972, which also gives a nice speedup.
1704
Richard Jonescebbefc2006-05-23 18:28:17 +00001705- Patch #1337051: reduced size of frame objects.
1706
1707- PyErr_NewException now accepts a tuple of base classes as its
1708 "base" parameter.
1709
Richard Jones7c88dcc2006-05-23 10:37:38 +00001710- Patch #876206: function call speedup by retaining allocated frame
1711 objects.
1712
Georg Brandl7b90e162006-05-18 07:01:27 +00001713- Bug #1462152: file() now checks more thoroughly for invalid mode
1714 strings and removes a possible "U" before passing the mode to the
1715 C library function.
1716
Neal Norwitz1004a532006-05-15 07:17:23 +00001717- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1718
Neal Norwitz373f0a72006-05-15 07:04:36 +00001719- Bug #1487966: Fix SystemError with conditional expression in assignment
1720
Martin v. Löwis879768d2006-05-11 13:28:43 +00001721- WindowsError now has two error code attributes: errno, which carries
1722 the error values from errno.h, and winerror, which carries the error
1723 values from winerror.h. Previous versions put the winerror.h values
1724 (from GetLastError()) into the errno attribute.
1725
Martin v. Löwis77736712006-05-04 05:51:03 +00001726- Patch #1475845: Raise IndentationError for unexpected indent.
1727
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001728- Patch #1479181: split open() and file() from being aliases for each other.
1729
Tim Peters44bd9862006-06-01 13:49:23 +00001730- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1731 methods were always silently ignored by dictionaries when comparing keys.
1732 They are now passed through (except when using the C API function
1733 ``PyDict_GetItem()``, whose semantics did not change).
1734
1735- Bug #1456209: In some obscure cases it was possible for a class with a
1736 custom ``__eq__()`` method to confuse dict internals when class instances
1737 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1738 No, you don't have any code that did this ;-)

1741-----------------
1742
Trent Mick960a3f82006-06-28 20:30:41 +00001743- Bug #1295808: expat symbols should be namespaced in pyexpat
1744
1745- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1746
Brett Cannon6ee7d012006-06-08 16:23:04 +00001747- Change binascii.hexlify to accept a read-only buffer instead of only a char
1748 buffer and actually follow its documentation.
1749
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001750- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1751
Nick Coghlanc649ec52006-05-29 12:43:05 +00001752- Patch #1478788 (modified version): The functional extension module has
1753 been renamed to _functools and a functools Python wrapper module added.
1754 This provides a home for additional function related utilities that are
1755 not specifically about functional programming. See PEP 309.
1756
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001757- Patch #1493701: performance enhancements for struct module.

Georg Brandl378d5922006-05-17 14:26:50 +00001759- Patch #1490224: time.altzone is now set correctly on Cygwin.
1760
Georg Brandl8d3342b2006-05-16 07:38:27 +00001761- Patch #1435422: zlib's compress and decompress objects now have a
1762 copy() method.
1763
Andrew MacIntyre92913322006-06-13 15:04:24 +00001764- Patch #1454481: thread stack size is now tunable at runtime for thread
1765 enabled builds on Windows and systems with Posix threads support.
1766
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001767- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1768 (up to the system limit of 32K characters).
1769
1770- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1771 As a result, these functions now raise WindowsError instead of OSError.
1772
Tim Peters7a822da2006-05-25 21:50:17 +00001773- ``time.clock()`` on Win64 should use the high-performance Windows
1774 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1775 Windows platforms).
1776
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001777- Calling Tk_Init twice is refused if the first call failed as that
1778 may deadlock.
1779
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001780- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1781 accept it without potentially using an uninitialized pointer.
1782
1783- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1784 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

Gregory P. Smith372b5832006-06-05 18:48:21 +00001790- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1791 parameter is supplied. [SF pybsddb bug #1477863]
1792
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001793- bsddb: the __len__ method of a DB object has been fixed to return correct
1794 results. It could previously incorrectly return 0 in some cases.
1795 Fixes SF bug 1493322 (pybsddb bug 1184012).
1796
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001797- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1798 aborts the db transaction safely when a modifier callback fails.
1799 Fixes SF python patch/bug #1408584.
1800
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001801- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001802 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001803 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1804 database calls that would previously deadlock. [SF python bug #775414]

Tim Peters43898b42006-06-14 04:09:25 +00001836- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1837 guarantee that adjacent triples in the return list always describe
1838 non-adjacent blocks. Previously, a pair of matching blocks could end
1839 up being described by multiple adjacent triples that formed a partition
1840 of the matching pair.

Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001850- The wsgiref package has been added to the standard library.
1851
Nick Coghlan676725d2006-06-08 13:54:49 +00001852- The functions update_wrapper() and wraps() have been added to the functools

1855
Tim Petersd6a9eef2006-06-05 01:48:21 +00001856- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1857 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001858
Martin v. Löwis3f767792006-06-04 19:36:28 +00001859- Patch #1359618: Speed up charmap encoder by using a trie structure
1860 for lookup.
1861
Tim Petersd609b1a2006-06-02 23:22:51 +00001862- The functions in the ``pprint`` module now sort dictionaries by key
1863 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1864 if and only if its display required more than one line, although that
1865 wasn't documented. The new behavior increases predictability; e.g.,
1866 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1867
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001868- Patch #1497027: try HTTP digest auth before basic auth in urllib2

Georg Brandlb89316f2006-05-17 15:51:16 +00001878- Patch #1180296: Two new functions were added to the locale module:
1879 format_string() to get the effect of "format % items" but locale-aware,
1880 and currency() to format a monetary number with currency sign.

1893 a couple of issues, notably handling of long file names using the
1894 GNU LONGNAME extension.
1895
1896- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1897 new flag when ``name`` is already the name of an option flag.
1898
1899- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1900 package.

1944-----------------
1945
Thomas Heller1b046642006-04-18 18:51:06 +00001946- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1947 by converting these apis from macros into exported functions again:
1948
1949 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1950 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1951 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne

1953 PyRun_String Py_CompileString
1954
Martin v. Löwis45294a92006-04-18 06:24:08 +00001955- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1956
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001957- All uses of PyStructSequence_InitType have been changed to initialize
1958 the type objects only once, even if the interpreter is initialized
1959 multiple times.
1960
Neal Norwitz61546162006-04-14 05:20:28 +00001961- Bug #1454485, array.array('u') could crash the interpreter. This was
1962 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1963 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1964
1965- Py_UNICODE is unsigned. It was always documented as unsigned, but
1966 due to a bug had a signed value in previous versions.
1967
Tim Peters3a5e8b12006-04-11 01:44:07 +00001968- Patch #837242: ``id()`` of any Python object always gives a positive
1969 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1970 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001971 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001972 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001973
Tim Peters3a5e8b12006-04-11 01:44:07 +00001974 def __hash__(self):
1975 return id(self) # WRONG
1976
1977 because a hash result must be a (short) Python int but it was always
1978 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001979 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001980 was always usable as a hash value before this patch. That's no longer
1981 necessarily so.
1982
1983- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001984 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001985 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001986 #1454844)
1987
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001988- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1989 involving generators that have paused outside of any ``try`` or ``with``
1990 blocks. (In 2.5a1, a paused generator that was part of a reference
1991 cycle could not be garbage collected, regardless of whether it was
1992 paused in a ``try`` or ``with`` block.)

2022 abusing errno.
2023
Tim Peters711bf302006-04-25 03:31:36 +00002024- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2025 a doctest to be skipped (the code is not run, and the expected output
2026 or exception is ignored).
2027
Nick Coghlanda2268f2006-04-24 04:37:15 +00002028- Fixed contextlib.nested to cope with exceptions being raised and
2029 caught inside exit handlers.
2030
Greg Wardab05edc2006-04-23 03:47:58 +00002031- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2032 hex, octal, or binary; add ``append_const`` action; keep going if
2033 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2034 added ``epilog`` for better help generation).
2035
Tim Peters21fbd572006-04-21 21:18:10 +00002036- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2037 called from a thread spawned as a side effect of importing a module.
2038
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002039- The pydoc module now supports documenting packages contained in
2040 .zip or .egg files.
2041
2042- The pkgutil module now has several new utility functions, such
2043 as ``walk_packages()`` to support working with packages that are either
2044 in the filesystem or zip files.
2045
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002046- The mailbox module can now modify and delete messages from
2047 mailboxes, in addition to simply reading them. Thanks to Gregory
2048 K. Johnson for writing the code, and to the 2005 Google Summer of
2049 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002050
Tim Petersc7605f22006-04-17 21:12:33 +00002051- The ``__del__`` method of class ``local`` in module ``_threading_local``
2052 returned before accomplishing any of its intended cleanup.
2053
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002054- Patch #790710: Add breakpoint command lists in pdb.

Martin v. Löwis4be4e652006-04-17 19:25:49 +00002080- The Makefile now has a reindent target, which runs reindent.py on
2081 the library.
2082
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002083- Patch #1470875: Building Python with MS Free Compiler
2084
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00002085- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002086
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002087- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2088 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002089 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002090 CXX from --with-cxx-main, see description in README.
2091
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002092- Patch #1429775: Link extension modules with the shared libpython.
2093
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002094- Fixed a libffi build problem on MIPS systems.
2095
Tim Peters8931ff12006-05-13 23:28:20 +00002096- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2097 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2098 and "%zu" for unsigned integers of type ``size_t``.
2099
Anthony Baxter51bcb682006-04-05 14:51:42 +00002100Tests
2101-----
2102
Nick Coghlanda2268f2006-04-24 04:37:15 +00002103- test_contextlib now checks contextlib.nested can cope with exceptions
2104 being raised and caught inside exit handlers.
2105
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002106- test_cmd_line now checks operation of the -m and -c command switches
2107
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002108- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2109 it separately and by hand. It also wasn't cleaning up its changes to
2110 the current Decimal context.
2111
Thomas Woutersabd08882006-04-26 15:53:30 +00002112- regrtest.py now has a -M option to run tests that test the new limits of
2113 containers, on 64-bit architectures. Running these tests is only sensible
2114 on 64-bit machines with more than two gigabytes of memory. The argument
2115 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +00002123Documentation
2124-------------
2125
Tim Petersb06d28c2006-05-12 01:57:59 +00002126- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2127
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002128- PEP 343: Added Context Types section to the library reference
2129 and attempted to bring other PEP 343 related documentation into
2130 line with the implementation and/or python-dev discussions.
2131
Tim Peters8dc73d22006-04-24 02:03:16 +00002132- Bug #1337990: clarified that ``doctest`` does not support examples
2133 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002136What's New in Python 2.5 alpha 1?
2137=================================
2138
Anthony Baxterebed3f62006-04-03 15:03:44 +00002139*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002140
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002141Core and builtins
2142-----------------
2143
Nick Coghlan43832302006-04-23 17:04:07 +00002144- PEP 338: -m command line switch now delegates to runpy.run_module
2145 allowing it to support modules in packages and zipfiles
2146
Martin v. Löwisc661b882006-04-20 04:54:23 +00002147- On Windows, .DLL is not an accepted file name extension for
2148 extension modules anymore; extensions are only found if they
2149 end in .PYD.
2150
Martin v. Löwisea62d252006-04-03 10:56:49 +00002151- Bug #1421664: sys.stderr.encoding is now set to the same value as
2152 sys.stdout.encoding.
2153
Neal Norwitz92e212f2006-04-03 04:48:37 +00002154- __import__ accepts keyword arguments.
2155
Georg Brandlccadf842006-03-31 18:54:53 +00002156- Patch #1460496: round() now accepts keyword arguments.
2157
Anthony Baxter262c00a2006-03-30 10:53:17 +00002158- Fixed bug #1459029 - unicode reprs were double-escaped.
2159
Hye-Shik Changd478f342006-03-23 12:32:36 +00002160- Patch #1396919: The system scope threads are reenabled on FreeBSD
2161 5.4 and later versions.
2162
Neal Norwitze98ccf62006-03-23 05:39:47 +00002163- Bug #1115379: Compiling a Unicode string with an encoding declaration
2164 now gives a SyntaxError.
2165
Georg Brandlabd1ff82006-03-18 07:59:59 +00002166- Previously, Python code had no easy way to access the contents of a
2167 cell object. Now, a ``cell_contents`` attribute has been added
2168 (closes patch #1170323).
2169
Tim Peterscf79aac2006-03-16 01:14:46 +00002170- Patch #1123430: Python's small-object allocator now returns an arena to
2171 the system ``free()`` when all memory within an arena becomes unused
2172 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2173 freed. Some applications will see a drop in virtual memory size now,
2174 especially long-running applications that, from time to time, temporarily
2175 use a large number of small objects. Note that when Python returns an
2176 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002177 platform C library will in turn return that memory to the operating system.
2178 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002179 appears to be effective at least on Microsoft C and gcc-based systems.
2180 Thanks to Evan Jones for hard work and patience.
2181
Georg Brandl533ff6f2006-03-08 18:09:27 +00002182- Patch #1434038: property() now uses the getter's docstring if there is
2183 no "doc" argument given. This makes it possible to legitimately use
2184 property() as a decorator to produce a read-only property.
2185
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002186- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2187 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2188 of requiring an int or long in slicing and a few other contexts, enabling
2189 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2190
Neal Norwitz995acdf2006-03-07 05:01:00 +00002191- Fixed various bugs reported by Coverity's Prevent tool.
2192
Brett Cannonbf364092006-03-01 04:25:17 +00002193- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2194 new exception base class, BaseException, which has a new message attribute.
2195 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2196 Raising a string exception now raises a DeprecationWarning.
2197
Thomas Woutersfb609f42006-02-28 16:37:25 +00002198- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2199 explicitly relative, using 'from .module import name' to mean 'from the same
2200 package as this module is in. Imports without dots still default to the
2201 old relative-then-absolute, unless 'from __future__ import
2202 absolute_import' is used.
2203
Brett Cannona7446e32006-02-27 23:39:10 +00002204- Properly check if 'warnings' raises an exception (usually when a filter set
2205 to "error" is triggered) when raising a warning for raising string
2206 exceptions.
2207
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002208- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002209 The name was removed from Include/code.h.
2210
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002211- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002212
Guido van Rossum1968ad32006-02-25 22:38:04 +00002213- Patch 1433928:
2214 - The copy module now "copies" function objects (as atomic objects).
2215 - dict.__getitem__ now looks for a __missing__ hook before raising
2216 KeyError.
2217
Tim Peters84ef21c2006-02-28 20:39:06 +00002218- PEP 343: with statement implemented. Needs ``from __future__ import
2219 with_statement``. Use of 'with' as a variable will generate a warning.
2220 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002221 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002222 The following objects have __context__ methods:
2223 - The built-in file type.
2224 - The thread.LockType type.
2225 - The following types defined by the threading module:
2226 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2227 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002228
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002229- Fix the encodings package codec search function to only search
2230 inside its own package. Fixes problem reported in patch #1433198.
2231
2232 Note: Codec packages should implement and register their own
2233 codec search function. PEP 100 has the details.
2234
Tim Peters9ea89d22006-06-04 03:26:02 +00002235- PEP 353: Using ``Py_ssize_t`` as the index type.
2236
2237- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2238 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2239 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2240 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2241 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002242
Neal Norwitzfc76d632006-01-10 06:03:13 +00002243- Patch #1400181, fix unicode string formatting to not use the locale.
2244 This is how string objects work. u'%f' could use , instead of .
2245 for the decimal point. Now both strings and unicode always use periods.
2246
Neal Norwitz671b9e32006-01-09 07:07:12 +00002247- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2248 configure would break checking curses.h.
2249
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002250- Bug #959576: The pwd module is now builtin. This allows Python to be
2251 built on UNIX platforms without $HOME set.
2252
Neal Norwitzc10978f2005-12-19 06:07:16 +00002253- Bug #1072182, fix some potential problems if characters are signed.
2254
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002255- Bug #889500, fix line number on SyntaxWarning for global declarations.
2256
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002257- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2258
Neal Norwitze7214a12005-12-18 05:03:17 +00002259- Support for converting hex strings to floats no longer works.
2260 This was not portable. float('0x3') now raises a ValueError.
2261
Barry Warsaw2a38a862005-12-18 01:27:35 +00002262- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002263 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002264 is now displayed in interactive prompt banner.
2265
Georg Brandlfa166682005-12-17 21:45:17 +00002266- Implementation of PEP 341 - Unification of try/except and try/finally.
2267 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002268 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002269
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002270- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2271 now encodes backslash correctly.
2272
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002273- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2274
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002275- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002276 and long longs.
2277
Neal Norwitz67715f02005-11-09 06:59:35 +00002278- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002279 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002280 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002281
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002282- Replaced most Unicode charmap codecs with new ones using the
2283 new Unicode translate string feature in the builtin charmap
2284 codec; the codecs were created from the mapping tables available
2285 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2286 encodings now include a mapping for the Apple logo)
2287
Tim Peterse3547fd2005-12-16 23:13:57 +00002288- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002289
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002290- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002291
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002292- A new AST parser implementation was completed. The abstract
2293 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002294 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002295
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002296- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002297 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2298
Neal Norwitz708e51a2005-10-03 04:48:15 +00002299- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2300
Neal Norwitz11bd1192005-10-03 00:54:56 +00002301- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2302 Provide a warning when a directory is passed on the command line.
2303
Neal Norwitz40d37812005-10-02 01:48:49 +00002304- Fix segfault with invalid coding.
2305
2306- SF bug #772896: unknown encoding results in MemoryError.
2307
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002308- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002309 supported a __len__() method which evaluated to False when the iterator
2310 was empty.
2311
Guido van Rossum630db602005-09-20 18:49:54 +00002312- On 64-bit platforms, when __len__() returns a value that cannot be
2313 represented as a C int, raise OverflowError.
2314
Skip Montanarof8948ca2005-09-19 03:54:46 +00002315- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002316 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002317
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002318- SF bug #893549: parsing keyword arguments was broken with a few format
2319 codes.
2320
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002321- Changes donated by Elemental Security to make it work on AIX 5.3
2322 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2323 bug #105470: test_pwd fails on 64bit system (Opteron).
2324
Guido van Rossum539c6622005-09-14 17:49:54 +00002325- Changes donated by Elemental Security to make it work on HP-UX 11 on
2326 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2327
Georg Brandl4550b8d2005-08-26 06:43:52 +00002328- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002329 (fixes bug #1119418).
2330
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002331- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2332
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002333- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2334 exceptions that cause a function to exit.
2335
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002336- The implementation of set() and frozenset() was revised to use its
2337 own internal data structure. Memory consumption is reduced by 1/3
2338 and there are modest speed-ups as well. The API is unchanged.
2339
Tim Petersde7990b2005-07-17 23:45:23 +00002340- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2341
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002342- SF bug #1229429: PyObject_CallMethod failed to decrement some
2343 reference counts in some error exit cases.
2344
Tim Petersecc6e6a2005-07-10 22:30:55 +00002345- SF bug #1185883: Python's small-object memory allocator took over
2346 a block managed by the platform C library whenever a realloc specified
2347 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002348 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002349 portable way to copy data from the C-managed block into Python's
2350 small-object space without risking a memory fault. Python's small-object
2351 realloc now leaves such blocks under the control of the platform C
2352 realloc.

Michael W. Hudsonb8963812005-07-05 15:21:58 +00002354- SF bug #1232517: An overflow error was not detected properly when
2355 attempting to convert a large float to an int in os.utime().
2356
Raymond Hettinger3296e692005-06-29 23:29:56 +00002357- SF bug #1224347: hex longs now print with lowercase letters just
2358 like their int counterparts.
2359
Michael W. Hudson188d4362005-06-20 16:52:57 +00002360- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2361 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2362 interpreter states; back out that fix and do a better job (see
2363 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2364 for a longer write-up of the problem).
2365
Michael W. Hudsondf888462005-06-03 14:41:55 +00002366- SF patch #1180995: marshal now uses a binary format by default when
2367 serializing floats.
2368
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002369- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2370 the routines that promise to produce IEEE 754 binary representations
2371 of floats now simply copy bytes around.
2372
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002373- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2374 278.
2375
Brett Cannonc3647ac2005-04-26 03:45:26 +00002376- patch #1109424: int, long, float, complex, and unicode now check for the
2377 proper magic slot for type conversions when subclassed. Previously the
2378 magic slot was ignored during conversion. Semantics now match the way
2379 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002380 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002381 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002382 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002383
Barry Warsawc8d907c2005-04-19 23:43:40 +00002384- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2385 NULL, now raise an AttributeError when attempting to set or delete the
2386 attribute. Previously a TypeError was raised, but this was inconsistent
2387 with the equivalent pure-Python implementation.
2388
Michael W. Hudson774479c2005-04-18 08:46:17 +00002389- It is now safe to call PyGILState_Release() before
2390 PyEval_InitThreads() (note that if there is reason to believe there
2391 are multiple threads around you still must call PyEval_InitThreads()
2392 before using the Python API; this fix is for extension modules that
2393 have no way of knowing if Python is multi-threaded yet).
2394
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002395- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2396 disabled caused a crash.
2397
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002398- Bug #1165306: instancemethod_new allowed the creation of a method
2399 with im_class == im_self == NULL, which caused a crash when called.
2400
Tim Petersecc6e6a2005-07-10 22:30:55 +00002401- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002402 fixes the crash seen in bug #1165761
2403
Raymond Hettinger96229b12005-03-11 06:49:40 +00002404- Added two new builtins, any() and all().
2405
Brett Cannon409d8f22005-03-05 06:47:57 +00002406- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002407 (e.g., ``class C(): pass`` is no longer a syntax error).
2408 Patch #1176012 added support to the 'parser' module and 'compiler' package
2409 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002410
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002411- Patch #1115086: Support PY_LONGLONG in structmember.
2412
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002413- Bug #1155938: new style classes did not check that __init__() was
2414 returning None.
2415
Tim Petersecc6e6a2005-07-10 22:30:55 +00002416- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002417 ('\') with a specific error message.
2418
Martin v. Löwisff232d72005-03-03 09:24:38 +00002419- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2420
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002421- Bug #1124295: the __name__ attribute of file objects was
2422 inadvertently made inaccessible in restricted mode.
2423
Tim Petersecc6e6a2005-07-10 22:30:55 +00002424- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002425 an ferror() call.
2426
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002427- min() and max() now support key= arguments with the same meaning as in
2428 list.sort().
2429
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002430- The peephole optimizer now performs simple constant folding in expressions:
2431 (2+3) --> (5).
2432
Raymond Hettingera422c342005-01-11 03:03:27 +00002433- set and frozenset objects can now be marshalled. SF #1098985.
2434
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002435- Bug #1077106: Poor argument checking could cause memory corruption
2436 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002437
Jeremy Hyltonab630502005-02-04 18:44:06 +00002438- The parser did not complain about future statements in illegal
2439 positions. It once again reports a syntax error if a future
2440 statement occurs after anything other than a doc string.
2441
Neil Schemenauercf52c072005-08-12 17:34:58 +00002442- Change the %s format specifier for str objects so that it returns a
2443 unicode instance if the argument is not an instance of basestring and
2444 calling __str__ on the argument returns a unicode instance.
2445
Tim Petersf4e69282006-02-27 17:15:31 +00002446- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2447 current thread state when the auto-GIL-state machinery knows about
2448 it (since the thread state is being deleted, continuing to remember it
2449 can't help, but can hurt if another thread happens to get created with
2450 the same thread id).
2451
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002452Extension Modules

2469
2470- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2471
2472- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002473 is deprecated. The undocumented re.engine variable no longer exists.

2477
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002478- The unicodedata module was updated to the 4.1 version of the Unicode
2479 database. The 3.2 version is still available as unicodedata.db_3_2_0
2480 for applications that require this specific version (such as IDNA).
2481
Neal Norwitzb62c4332006-03-04 18:35:47 +00002482- The timing module is no longer built by default. It was deprecated

2484
Guido van Rossum1968ad32006-02-25 22:38:04 +00002485- Patch 1433928: Added a new type, defaultdict, to the collections module.

2503
Martin v. Löwis14694662006-02-03 12:54:16 +00002504- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2505 are reported, the limit on path name lengths is removed, and stat reports
2506 WindowsError now (instead of OSError).
2507
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002508- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

2583 the request code argument, which results in more C-like behaviour
2584 for large or negative values.
2585
Tim Petersecc6e6a2005-07-10 22:30:55 +00002586- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

2628
Raymond Hettingerb2594052004-12-05 09:25:51 +00002629- itertools.islice() now accepts None for the start and step arguments.

Tim Peters112aad32006-07-19 00:03:19 +00002641
Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002642- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2643 been renamed to have only a single underscore prefix. This was done to
2644 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002645
Nick Coghlan43832302006-04-23 17:04:07 +00002646- PEP 338: new module runpy defines a run_module function to support
2647 executing modules which provide access to source code or a code object
2648 via the PEP 302 import mechanisms.
2649
Anthony Baxter93f5b932006-04-03 08:05:07 +00002650- The email module's parsedate_tz function now sets the daylight savings

2658 in attribute values.
2659
Anthony Baxterc51ee692006-04-01 00:57:31 +00002660- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002661 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002662 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002663 module will not be built.
2664
Tim Petersc17976e2006-04-01 00:26:53 +00002665- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2666 aren't officially supported here, and trying to use them will probably
2667 raise an exception some day. But dicts have been allowed, and "mostly
2668 worked", so support for them won't go away without warning.
2669
Georg Brandl338ef7d2006-03-31 18:42:16 +00002670- Bug #1445068: getpass.getpass() can now be given an explicit stream
2671 argument to specify where to write the prompt.
2672
Georg Brandl22ec80b2006-03-31 18:25:44 +00002673- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2682 to make it easier to monitor when daemon threads have completed
2683 processing all enqueued tasks. Patch #1455676.
2684
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002685- popen2.Popen objects now preserve the command in a .cmd attribute.

2688
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002689- email 4.0 package now integrated. This is largely the same as the email 3.0
2690 package that was included in Python 2.3, except that PEP 8 module names are
2691 now used (e.g. mail.message instead of email.Message). The MIME classes
2692 have been moved to a subpackage (e.g. email.mime.text instead of
2693 email.MIMEText). The old names are still supported for now. Several
2694 deprecated Message methods have been removed and lots of bugs have been
2695 fixed. More details can be found in the email package documentation.
2696
Walter Dörwald40108c92006-03-27 08:15:44 +00002697- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2698 (a subclass of tuple) that provides incremental decoders and encoders
2699 (a way to use stateful codecs without the stream API). Python functions
2700 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2701 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2702 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002703
Walter Dörwald067db482006-03-15 22:17:27 +00002704- Patch #1359365: Calling next() on a closed StringIO.String object raises
2705 a ValueError instead of a StopIteration now (like file and cString.String do).
2706 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2707 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002708
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002709- A regrtest option -w was added to re-run failed tests in verbose mode.

2782 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2783 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2784 Ronald L. Rivest offered this advice for Python:
2785
2786 "The consensus of researchers in this area (at least as
2787 expressed at the NIST Hash Function Workshop 10/31/05),
2788 is that SHA-256 is a good choice for the time being, but
2789 that research should continue, and other alternatives may
2790 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002791
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002792- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandl5284b532005-06-26 22:54:58 +00002876
Georg Brandl2f210b62005-06-26 22:09:06 +00002877- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
2878
Georg Brandlfbff1bc2005-06-26 21:36:25 +00002879- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
2880 error messages.
2881
Georg Brandl379f99d2005-06-26 21:09:38 +00002882- Bug #1108948: Cookie.py produced invalid JavaScript code.
2883
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00002884- The tokenize module now detects and reports indentation errors.
2885 Bug #1224621.
2886
Raymond Hettinger68c04532005-06-10 11:05:19 +00002887- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002888 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002889 the generate_tokens() function now accepts a callable argument that
2890 terminates by raising StopIteration.
2891
Georg Brandl9166e1a2005-06-04 09:20:03 +00002892- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2893
Georg Brandl268e61c2005-06-03 14:28:50 +00002894- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2895 component of the path.
2896
Skip Montanaro174dd222005-05-14 20:54:16 +00002897- Patch #1120353: The xmlrpclib module provides better, more transparent,
2898 support for datetime.{datetime,date,time} objects. With use_datetime set
2899 to True, applications shouldn't have to fiddle with the DateTime wrapper
2900 class at all.
2901
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002902- distutils.commands.upload was added to support uploading distribution
2903 files to PyPI.
2904
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002905- distutils.commands.register now encodes the data as UTF-8 before posting
2906 them to PyPI.
2907
Raymond Hettinger267b8682005-03-27 10:47:39 +00002908- decimal operator and comparison methods now return NotImplemented
2909 instead of raising a TypeError when interacting with other types. This
2910 allows other classes to implement __radd__ style methods and have them
2911 work as expected.
2912
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002913- Bug #1163325: Decimal infinities failed to hash. Attempting to
2914 hash a NaN raised an InvalidOperation instead of a TypeError.
2915
Tim Petersecc6e6a2005-07-10 22:30:55 +00002916- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002917 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2918
Martin v. Löwis00a73e72005-03-04 19:40:34 +00002919- Patch #1043890: Add extractall method to tarfile.

2922 to build.
2923
Martin v. Löwis637431b2005-03-03 23:12:42 +00002924- Patch #1103407: Properly deal with tarfile iterators when untarring
2925 symbolic links on Windows.

2948
Raymond Hettingerbab41432005-02-05 01:31:19 +00002949- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2950
Guido van Rossumd0641422005-02-03 15:01:24 +00002951- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2952 disables recursive traversal through instance attributes, which can
2953 be exploited in various ways.
2954
Tim Peterse3547fd2005-12-16 23:13:57 +00002955- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002956 flags on the HTTP listening socket.
2957
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002958- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2959 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2960
Fred Drakefbdeaad2006-07-29 16:56:15 +00002961- Patches #893642, #1039083: add allow_none, encoding arguments to
2962 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002963
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002964- Bug #1110478: Revert os.environ.update to do putenv again.
2965
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002966- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2967
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002968- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2969
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002970- Enhancements to the csv module:
2971
2972 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002973 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002974 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002975 + Dialect parameter parsing has been re-implemented to improve error
2976 reporting.
2977 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2978 dictates.
2979 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002980 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002981 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002982 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2983 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002984 + reader now allows \r characters to be quoted (previously it only allowed
2985 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002986 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002987 + Dialect classes passed to the module are no longer instantiated by
2988 the module before being parsed (the former validation scheme required
2989 this, but the mechanism was unreliable).
2990 + The dialect registry now contains instances of the internal
2991 C-coded dialect type, rather than references to python objects.
2992 + the internal c-coded dialect type is now immutable.
2993 + register_dialect now accepts the same keyword dialect specifications
2994 as the reader and writer, allowing the user to register dialects
2995 without first creating a dialect class.
2996 + a configurable limit to the size of parsed fields has been added -
2997 previously, an unmatched quote character could result in the entire
2998 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002999 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003000 the parser field size limit (returning the former limit). The initial
3001 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003002 + A line_num attribute has been added to the reader object, which tracks
3003 the number of lines read from the source iterator. This is not
3004 the same as the number of records returned, as records can span
3005 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003006 + reader and writer objects were not being registered with the cyclic-GC.
3007 This has been fixed.
3008
Brett Cannone6539c42005-01-08 02:43:53 +00003009- _DummyThread objects in the threading module now delete self.__block that is
3010 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3011 lock primitives tend to be limited in number and thus should not be wasted on
3012 a _DummyThread object. Fixes bug #1089632.
3013
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003014- The imghdr module now detects Exif files.
3015
Raymond Hettinger6065d322004-12-20 23:51:53 +00003016- StringIO.truncate() now correctly adjusts the size attribute.
3017 (Bug #951915).
3018
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003019- locale.py now uses an updated locale alias table (built using
3020 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3021 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003022 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003023
Raymond Hettinger3557f422004-12-07 12:02:02 +00003024- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3025
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003026- the pickle module no longer accepts the deprecated None option in the
3027 args tuple returned by __reduce__().
3028
Brett Cannon84667c02004-12-07 03:25:18 +00003029- optparse now optionally imports gettext. This allows its use in setup.py.
3030
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003031- the pickle module no longer uses the deprecated bin parameter.
3032
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003033- the shelve module no longer uses the deprecated binary parameter.
3034
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003035- the pstats module no longer uses the deprecated ignore() method.
3036
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003037- the filecmp module no longer uses the deprecated use_statcache argument.
3038
Raymond Hettinger664347b2004-12-04 21:21:53 +00003039- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3040 extended or overridden by subclasses. Formerly, the subclassed method would
3041 be ignored by the rest of the module. (Bug #1078905).
3042
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003043- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003044 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003045
Walter Dörwald36733692004-12-22 12:50:50 +00003046- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3047 once when a size argument is given. This prevents a buffer overflow in the
3048 tokenizer with very long source lines.
3049
Barry Warsaw538561e2006-01-01 21:48:54 +00003050- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3051 immediately after creating the object, without any intervening
3052 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003053
Skip Montanaro05885812005-01-16 20:48:27 +00003054- The reconvert.quote function can now emit triple-quoted strings. The
3055 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003056
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003057- ``UserString.MutableString`` now supports negative indices in
3058 ``__setitem__`` and ``__delitem__``
3059
Greg Ward40407942005-03-05 02:53:17 +00003060- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3061 correctly.
3062
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003063- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3064 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3065 character even if the user has passed a size parameter to get a proper
3066 line ending. Remove the special handling of a "\r\n" that has been split
3067 between two lines.
3068
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003069- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3070 about illegal code points. The codec now supports PEP 293 style error
3071 handlers.
3072
Walter Dörwald78a78b02005-09-01 12:04:29 +00003073- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003074 from the input stream, so that the output is a byte string in the correct
3075 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003076
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003077- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3078 considering it exactly like a '*'.
3079
Walter Dörwald007f8df2005-10-09 19:42:27 +00003080- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3081 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003082
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003083- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3084
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003085- Patch #1413711: Certain patterns of differences were making difflib
3086 touch the recursion limit.
3087
Walter Dörwald58917a62006-03-31 15:26:22 +00003088- Bug #947906: An object oriented interface has been added to the calendar
3089 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003090 called as a script (e.g. via ``python -mcalendar``). Localized month and
3091 weekday names can be ouput (even if an exotic encoding is used) using
3092 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003093

Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003108- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3109 The zlib module is now builtin on Windows.
3110
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003111- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3112
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003113- Bug #1189330: configure did not correctly determine the necessary
3114 value of LINKCC if python was built with GCC 4.0.
3115
Trent Mick8321b422005-07-26 02:29:21 +00003116- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3117 vulnerability in zlib 1.2.1 and 1.2.2.
3118
Brett Cannon08cd5982005-04-24 22:26:38 +00003119- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3120 flags that change binary compatibility. Changes were also made to
3121 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003122 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003123
Bob Ippolitoed233462005-03-29 13:47:59 +00003124- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3125 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3126 no longer exists). This configure patch makes things right.
3127
Martin v. Löwise2713be2005-03-08 15:03:08 +00003128- Bug #1158607: Build with --disable-unicode again.
3129
Brett Cannon46d96232005-02-16 00:07:19 +00003130- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3131 defined. Discovered as a result of not being able to build on OS X.
3132
Brett Cannon516592f2004-12-07 00:42:59 +00003133- setup.py now uses the directories specified in LDFLAGS using the -L option
3134 and in CPPFLAGS using the -I option for adding library and include
3135 directories, respectively, for compiling extension modules against. This has
3136 led to the core being compiled using the values in CPPFLAGS. It also removes
3137 the need for the special-casing of both DarwinPorts and Fink for darwin since
3138 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3139 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3140 Fink, ``-I/opt/local/include`` for DarwinPorts).

Brett Cannon43802422005-02-10 20:48:03 +00003142- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3143 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3144 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3145 Closes bug #1096244. Thanks Gregory Bond.

Tim Petersc9d78aa2006-03-26 23:27:58 +00003150- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3151 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3152 is obtained via the ``PyObject_`` family, it must be released via the
3153 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3154 always been officially true, but when Python's small-object allocator was
3155 introduced, an attempt was made to cater to a few extension modules
3156 discovered at the time that obtained memory via ``PyObject_New`` but
3157 released it via ``PyMem_DEL``. It's years later, and if such code still
3158 exists it will fail now (probably with segfaults, but calling wrong
3159 low-level memory management functions can yield many symptoms).

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003165- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3166 mapping argument now. This string is used as a mapping table. Byte values
3167 greater than the length of the string and 0xFFFE are treated as undefined
3168 mappings.
