12Core and builtins
13-----------------
Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +000014
Guido van Rossumaa975432008-04-10 22:43:58 +000015- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
16 having a self-referential tuple, which is possible from C code. Nor did
17 object's tp_str consider that a type's tp_str could do something that could
18 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
19 respectively, fixed the issues. (Backport of r58288 from trunk.)
20
Georg Brandld9f1da02008-03-29 01:50:46 +000021- Patch #1442: properly report exceptions when the PYTHONSTARTUP file
22 cannot be executed.
23
Amaury Forgeot d'Arc8432d862008-03-28 20:45:42 +000024- The compilation of a class nested in another class used to leak one
25 reference on the outer class name.
26
Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +000027- Issue #1477: With narrow Unicode builds, the unicode escape sequence
28 \Uxxxxxxxx did not accept values outside the Basic Multilingual Plane. This
29 affected raw unicode literals and the 'raw-unicode-escape' codec. Now
30 UTF-16 surrogates are generated in this case, like normal unicode literals
31 and the 'unicode-escape' codec.
32
Neal Norwitzb3635f92008-03-18 04:17:36 +000033- Issue #2321: use pymalloc for unicode object string data to reduce
34 memory usage in some circumstances.
Andrew M. Kuchlingbe0adfc2008-02-23 17:18:19 +000035
Sean Reifscheider4af861c2008-03-20 17:39:31 +000036- Issue #2238: Some syntax errors in *args and **kwargs expressions could give
37 bogus error messages.
38
Gregory P. Smith14acde32008-04-09 23:41:13 +000039- Issue #2587: In the C API, PyString_FromStringAndSize() takes a signed size
40 parameter but was not verifying that it was greater than zero. Values
41 less than zero will now raise a SystemError and return NULL to indicate a
42 bug in the calling C code.

47
Amaury Forgeot d'Arc8d904c32008-04-22 21:17:18 +000048- Issue #2670: Fix a failure in urllib2.build_opener(), when passed two
49 handlers that derive the same default base class.
50
Amaury Forgeot d'Arc198e3532008-03-27 23:41:59 +000051- Issue #2495: tokenize.untokenize now inserts a space between two consecutive
52 string literals; previously, ["" ""] was rendered as [""""], which is
53 incorrect python code.
54
Mark Dickinsonbfdbfd42008-03-25 18:58:13 +000055- Issue #2482: Make sure that the coefficient of a Decimal is always
56 stored as a str instance, not as a unicode instance. This ensures
57 that str(Decimal) is always an instance of str. This fixes a
58 regression from Python 2.5.1 to Python 2.5.2.
59
Mark Dickinson26c25d92008-03-25 14:35:25 +000060- Issue #2478: fix failure of decimal.Decimal(0).sqrt()

63 advertised in the docs.
64
Gregory P. Smitheff5a4e2008-03-18 19:24:40 +000065- Issue #1747858: Fix chown to work with large uid's and gid's on 64-bit
66 platforms.
67
Georg Brandlab61dce2008-03-06 07:46:26 +000068- Bug #2220: handle rlcompleter attribute match failure more gracefully.
69
Martin v. Löwis0e305552008-03-06 07:14:26 +000070- Bug #1725737: In distutil's sdist, exclude RCS, CVS etc. also in the
71 root directory, and also exclude .hg, .git, .bzr, and _darcs.
72
Andrew M. Kuchling37d4f7b2008-02-23 19:06:54 +000073- Bug #1389051: imaplib causes excessive memory fragmentation when reading
74 large messages.
75
Andrew M. Kuchling664553a2008-02-23 19:30:59 +000076- Bug #1389051, 1092502: fix excessively large memory allocations when
77 calling .read() on a socket object wrapped with makefile().
78
Andrew M. Kuchling05a19a52008-02-23 17:21:44 +000079- Bug #1433694: minidom's .normalize() failed to set .nextSibling for

135
Amaury Forgeot d'Arcf1a71782008-01-24 23:42:08 +0000136- Issue #1920: "while 0" statements were completely removed by the compiler,
137 even in the presence of an "else" clause, which is supposed to be run when
138 the condition is false. Now the compiler correctly emits bytecode for the
139 "else" suite.
140

955-----------------
956
Neal Norwitz0bcafac2006-09-11 08:51:17 +0000957- Make _PyGILState_NoteThreadState() static, it was not used anywhere
958 outside of pystate.c and should not be necessary.
959
Brett Cannon19d76c52006-09-09 07:18:44 +0000960- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
961 allows calling unicode() on exceptions classes directly to succeed.
962
Georg Brandlecab6232006-09-06 06:47:02 +0000963- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
964 Also make sure that every exception class has __module__ set to
965 'exceptions'.
966
Georg Brandl37a9e572006-09-06 06:09:34 +0000967- Bug #1550983: emit better error messages for erroneous relative

Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000978- The return tuple from str.rpartition(sep) is (tail, sep, head) where
979 head is the original string if sep was not found.
980
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000981- Bug #1520864: unpacking singleton tuples in list comprehensions and
982 generator expressions (x for x, in ... ) works again. Fixing this problem
983 required changing the .pyc magic number. This means that .pyc files
984 generated before 2.5c2 will be regenerated.

1098
Neal Norwitz24b6f202006-09-05 04:43:56 +00001099- Fix infinite recursion when subclassing long and overriding __hash__.
1100
1101- Fix concatenation (+=) of long strings.
1102
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001103- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001104 compared equal or unequal to a string and a UnicodeDecodeError
1105 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001106
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001107 Instead, the equal (==) and unequal (!=) comparison operators will
1108 now issue a UnicodeWarning and interpret the two objects as
1109 unequal. The UnicodeWarning can be filtered as desired using
1110 the warning framework, e.g. silenced completely, turned into an
1111 exception, logged, etc.
1112
1113 Note that compare operators other than equal and unequal will still
1114 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001115
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001116- Fix segfault when doing string formatting on subclasses of long.
1117
1118- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1119 with new-style classes.
1120
1121- Fix bug related to __len__ functions returning negative values with
1122 classic classes.
1123
1124- Patch #1538606, Fix __index__() clipping. There were some problems
1125 discovered with the API and how integers that didn't fit into Py_ssize_t
1126 were handled. This patch attempts to provide enough alternatives
1127 to effectively use __index__.
1128
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001129- Bug #1536021: __hash__ may now return long int; the final hash
1130 value is obtained by invoking hash on the long int.
1131
Thomas Hellerab1049c2006-08-08 17:37:00 +00001132- Bug #1536786: buffer comparison could emit a RuntimeWarning.

1135 sys.stdin is closed.
1136
Thomas Heller74d36f02006-08-04 18:17:40 +00001137- On Windows, the PyErr_Warn function is now exported from
1138 the Python dll again.
1139
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001140- Bug #1191458: tracing over for loops now produces a line event
1141 on each iteration. Fixing this problem required changing the .pyc
1142 magic number. This means that .pyc files generated before 2.5c1
1143 will be regenerated.
1144
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001145- Bug #1333982: string/number constants were inappropriately stored
1146 in the byte code and co_consts even if they were not used, ie
1147 immediately popped off the stack.
1148
Georg Brandle9462c72006-08-04 18:03:37 +00001149- Fixed a reference-counting problem in property().

1153-------
1154
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001155- Fix a bug in the ``compiler`` package that caused invalid code to be
1156 generated for generator expressions.
1157
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001158- The distutils version has been changed to 2.5.0. The change to
1159 keep it programmatically in sync with the Python version running
1160 the code (introduced in 2.5b3) has been reverted. It will continue
1161 to be maintained manually as static string literal.
1162
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001163- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001164 and this cannot be converted to the required C type, an exception is
1165 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001166 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001167
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001168- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001169 an exception.
1170
Tim Peterscbdd3502006-09-05 01:47:53 +00001171- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001172 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001173 workarounds for clocks with low resolution, to stop the code yielding
1174 duplicate UUIDs.
1175
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001176- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1177 before raising SystemExit, allowing IDLE to honor quit() and exit().
1178
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001179- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1180
Georg Brandl7a1af772006-08-14 21:55:28 +00001181- Patch #1536071: trace.py should now find the full module name of a
1182 file correctly even on Windows.
1183
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001184- logging's atexit hook now runs even if the rest of the module has
1185 already been cleaned up.
1186

Thomas Heller1ce433e2006-08-14 16:20:04 +00001206- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1207 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1208
Thomas Heller86720042006-08-14 11:17:48 +00001209- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1210 uses the _as_parameter_ attribute when objects are passed to foreign
1211 function calls. The ctypes version number was changed to 1.0.1.
1212
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001213- Bug #1530559, struct.pack raises TypeError where it used to convert.
1214 Passing float arguments to struct.pack when integers are expected
1215 now triggers a DeprecationWarning.

1253
Tim Peters4643c2f2006-08-10 22:45:34 +00001254- Bug #1069160. Internal correctness changes were made to
1255 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1256 the documentation was changed to state that the return value
1257 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001260What's New in Python 2.5 beta 3?
1261================================

1265Core and builtins
1266-----------------
1267
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001268- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001269 returned a long (see PEP 353).
1270
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001271- Bug #1515471: string.replace() accepts character buffers again.
1272
Neal Norwitz07aadb12006-07-30 06:55:48 +00001273- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1274 This provides the proper warning for struct.pack().
1275 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1276
Neal Norwitz0d62a062006-07-30 06:53:31 +00001277- Patch #1531113: Fix augmented assignment with yield expressions.
1278 Also fix a SystemError when trying to assign to yield expressions.
1279
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001280- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1281 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1282 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1283 excessive filesystem operations during imports.
1284
Tim Petersbc24eee2006-07-27 01:14:53 +00001285- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1286 operations on signed longs that are formally undefined by C.
1287 Unfortunately, at least one compiler now cares about that, so complicated
1288 the code to make that compiler happy again.
1289
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001290- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1291
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001292- Patch #1232023: Stop including current directory in search
1293 path on Windows.
1294
Neal Norwitze1fdb322006-07-21 05:32:28 +00001295- Fix some potential crashes found with failmalloc.
1296
Neal Norwitze7563102006-07-17 01:00:16 +00001297- Fix warnings reported by Klocwork's static analysis tool.
1298
Neal Norwitz84be93b2006-07-16 01:50:38 +00001299- Bug #1512814, Fix incorrect lineno's when code within a function
1300 had more than 255 blank lines.
1301
Georg Brandl9dceedb2006-07-12 15:31:17 +00001302- Patch #1521179: Python now accepts the standard options ``--help`` and
1303 ``--version`` as well as ``/?`` on Windows.
1304
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001305- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001306 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001307 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001308
Tim Peters112aad32006-07-19 00:03:19 +00001309- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001310 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001311 new ``sys._current_frames()`` returns a dictionary with one entry,
1312 mapping the faux "thread id" 0 to the current frame.
1313
Ronald Oussoren3075e162006-07-25 20:28:55 +00001314- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001315

Neal Norwitza1f10902006-07-12 07:28:29 +00001317Library
1318-------
1319
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001320- Correction of patch #1455898: In the mbcs decoder, set final=False
1321 for stream decoder, but final=True for the decode function.
1322
Georg Brandl07fec3a2006-08-01 18:49:24 +00001323- os.urandom no longer masks unrelated exceptions like SystemExit or
1324 KeyboardInterrupt.
1325
Tim Peters4643c2f2006-08-10 22:45:34 +00001326- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001327 shutil.copytree on Windows
1328
Georg Brandle34ac7c2006-07-30 11:07:23 +00001329- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1330 refers to file descriptors, not file objects.
1331
Tim Peterscbdd3502006-09-05 01:47:53 +00001332- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001333 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001334 #1513611, and probably others.
1335
Georg Brandledd9b0d2006-07-29 09:33:26 +00001336- Bug #1441397: The compiler module now recognizes module and function
1337 docstrings correctly as it did in Python 2.4.
1338
Tim Peters6f681472006-07-27 23:44:37 +00001339- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1340 lost that tests are sorted by name before being run. This rarely
1341 matters for well-written tests, but can create baffling symptoms if
1342 side effects from one test to the next affect outcomes. ``DocTestFinder``
1343 has been changed to sort the list of tests it returns.
1344
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001345- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001346 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001347
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001348- Bug #978833: Really close underlying socket in _socketobject.close.
1349
Georg Brandldb232dc2006-08-20 13:15:43 +00001350- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1351 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001352
Georg Brandlcf0c1722006-07-26 07:23:32 +00001353- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1354 to recursive calls and call it with the failing package name.
1355
Martin v. Löwis0b483032006-07-25 09:53:12 +00001356- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1357
Georg Brandlc13c34c2006-07-24 14:09:56 +00001358- Patch #1515343: Fix printing of deprecated string exceptions with a
1359 value in the traceback module.
1360
Greg Ward48fae7a2006-07-23 16:05:51 +00001361- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1362
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001363- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1364
Brett Cannoncaebe222006-07-18 04:41:36 +00001365- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1366 argument tuple. For arguments where zero is illegal, the value is forced to
1367 the minimum value that is correct. This is to support an undocumented but
1368 common way people used to fill in inconsequential information in the time
1369 tuple pre-2.4.
1370
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001371- Patch #1220874: Update the binhex module for Mach-O.
1372
Barry Warsawb110bad2006-07-21 14:51:07 +00001373- The email package has improved RFC 2231 support, specifically for
1374 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1375 (name*0=<blah>) parameter continuations. This may change the types of
1376 values returned from email.message.Message.get_param() and friends.
1377 Specifically in some cases where non-encoded continuations were used,
1378 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1379 will just return the string (since non-encoded continuations don't have
1380 charset and language parts).
1381
1382 Also, whereas % values were decoded in all parameter continuations, they are
1383 now only decoded in encoded parameter parts.
1384
Ronald Oussoren3075e162006-07-25 20:28:55 +00001385- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1386
1387- Bug #1517996: IDLE now longer shows the default Tk menu when a
1388 path browser, class browser or debugger is the frontmost window on MacOS X
1389
Barry Warsaw00decd72006-07-27 23:43:15 +00001390- Patch #1520294: Support for getset and member descriptors in types.py,
1391 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1392 of an object against these built-in types and more importantly, for getting
1393 their docstrings printed in the interactive interpreter's help() function.

1398
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001399- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1400 a socket operation on a socket with a timeout, the exception will be
1401 caught correctly. Previously, the exception was not caught.
1402
Thomas Heller1393d6a2006-07-28 21:43:20 +00001403- Patch #1529514: The _ctypes extension is now compiled on more
1404 openbsd target platforms.
1405
Tim Peters9cab5932006-07-28 00:30:00 +00001406- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1407 a memory leak, affecting pickles and deep copies.
1408
Tim Petersbc24eee2006-07-27 01:14:53 +00001409- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1411
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001412- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1413
Thomas Hellerce049a02006-07-14 17:51:14 +00001414- Patch #1521817: Index range checking on ctypes arrays containing
1415 exactly one element enabled again. This allows iterating over these
1416 arrays, without the need to check the array size before.
1417
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001418- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001419 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001420 /dev/null in certain cases; this is now fixed.
1421
Thomas Heller47d7a062006-07-12 08:43:47 +00001422- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1423 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001424
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001425- Because of a misspelled preprocessor symbol, ctypes was always
1426 compiled without thread support; this is now fixed.
1427
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001428- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1429 methods now allow their database parameter to be None as the
1430 sleepycat API allows.
1431
Matt Flemingec926502006-07-28 11:27:27 +00001432- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1433 bluetooth API compared with Linux and FreeBSD.

1436-----
1437
1438- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1439 how long the test file should take to play. Now accepts taking 2.93 secs
1440 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1441
Georg Brandl4793aa32006-07-28 18:31:39 +00001442- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1443 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1444 run via ``regrtest.py``. Now they do.

1454- PythonLauncher now works correctly when the path to the script contains
1455 characters that are treated specially by the shell (such as quotes).
1456
1457- Bug #1527397: PythonLauncher now launches scripts with the working directory
1458 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001459 directory. That latter was an implementation accident and not what users

Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001471- Bug #1441486: The literal representation of -(sys.maxint - 1)
1472 again evaluates to a int object, not a long.
1473
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001474- Bug #1501934: The scope of global variables that are locally assigned
1475 using augmented assignment is now correctly determined.
1476
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001477- Bug #927248: Recursive method-wrapper objects can now safely
1478 be released.
1479
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001480- Bug #1417699: Reject locale-specific decimal point in float()
1481 and atof().
1482
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001483- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1484 omit a default "error" argument for NULL pointer. This allows
1485 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001486
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001487- Bug #1519018: 'as' is now validated properly in import statements.
1488
Neal Norwitz28746ab2006-07-09 22:14:42 +00001489- On 64 bit systems, int literals that use less than 64 bits are
1490 now ints rather than longs.
1491
Neal Norwitzed657552006-07-10 00:04:44 +00001492- Bug #1512814, Fix incorrect lineno's when code at module scope
1493 started after line 256.
1494
Tim Peters32a83612006-07-10 21:08:24 +00001495- New function ``sys._current_frames()`` returns a dict mapping thread
1496 id to topmost thread stack frame. This is for expert use, and is
1497 especially useful for debugging application deadlocks. The functionality
1498 was previously available in Fazal Majid's ``threadframe`` extension
1499 module, but it wasn't possible to do this in a wholly threadsafe way from
1500 an extension.

1509
Tim Peters32a83612006-07-10 21:08:24 +00001510- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001511 environment variable to be set in order to the SDK environment
1512 for finding the compiler, include files, etc.

Martin v. Löwis388a8c22006-07-06 19:28:03 +00001514- Bug #1515998: Properly generate logical ids for files in bdist_msi.
1515
Nick Coghlan2d792252006-07-06 13:47:18 +00001516- warnings.py now ignores ImportWarning by default
1517
Thomas Woutersadd19112006-07-05 11:03:49 +00001518- string.Template() now correctly handles tuple-values. Previously,
1519 multi-value tuples would raise an exception and single-value tuples would
1520 be treated as the value they contain, instead.
1521
Martin v. Löwisede77f52006-07-03 13:01:35 +00001522- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1530
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001531- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001532 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001533
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001534- Bug #1514703: Only setup canvas window in turtle when the canvas
1535 is created.
1536
Martin v. Löwis7596e832006-07-01 15:33:37 +00001537- Bug #1513223: .close() of a _socketobj now releases the underlying

1541 attribute values.
1542
1543- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1544 sgmllib ('[' and ']' were not accepted).
1545
Georg Brandl1be63af2006-06-28 20:23:25 +00001546- Fix a bug in the turtle module's end_fill function.
1547
Brett Cannon53ab5b72006-06-22 16:49:14 +00001548- Bug #1510580: The 'warnings' module improperly required that a Warning
1549 category be either a types.ClassType and a subclass of Warning. The proper
1550 check is just that it is a subclass with Warning as the documentation states.
1551
Georg Brandlad29e632006-06-21 17:45:17 +00001552- The compiler module now correctly compiles the new try-except-finally
1553 statement (bug #1509132).
1554
Neal Norwitz60373cd2006-06-22 06:30:50 +00001555- The wsgiref package is now installed properly on Unix.
1556
Vinay Sajip28e57612006-07-01 10:45:20 +00001557- A bug was fixed in logging.config.fileConfig() which caused a crash on
1558 shutdown when fileConfig() was called multiple times.
1559
Gerhard Häring762fbd32006-07-02 17:48:30 +00001560- The sqlite3 module did cut off data from the SQLite database at the first
1561 null character before sending it to a custom converter. This has been fixed
1562 now.

Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001564Extension Modules
1565-----------------
1566
Tim Peters112aad32006-07-19 00:03:19 +00001567- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1568 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1569 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001570
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001571- Assigning None to pointer type fields in ctypes structures possible
1572 overwrote the wrong fields, this is fixed now.
1573
1574- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1575 on non-Windows platforms.
1576
1577- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1578 integer or long, without range checking.
1579
1580- Patch #1517790: It is now possible to use custom objects in the ctypes
1581 foreign function argtypes sequence as long as they provide a from_param
1582 method, no longer is it required that the object is a ctypes type.
1583
1584- The '_ctypes' extension module now works when Python is configured
1585 with the --without-threads option.
1586
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001587- Bug #1513646: os.access on Windows now correctly determines write
1588 access, again.
1589
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001590- Bug #1512695: cPickle.loads could crash if it was interrupted with
1591 a KeyboardInterrupt.
1592
Neal Norwitza12aa882006-07-06 06:45:08 +00001593- Bug #1296433: parsing XML with a non-default encoding and
1594 a CharacterDataHandler could crash the interpreter in pyexpat.
1595
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001596- Patch #1516912: improve Modules support for OpenVMS.

Martin v. Löwisd73168d2006-07-14 09:58:55 +00001601- Automate Windows build process for the Win64 SSL module.
1602
Tim Peters32a83612006-07-10 21:08:24 +00001603- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001604 Previously, the slight difference could cause compilation errors of the
1605 'zlib' module on systems with more than one version of zlib.
1606
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001607- The MSI compileall step was fixed to also support a TARGETDIR
1608 with spaces in it.

Martin v. Löwis88ef6372006-07-06 06:55:58 +00001610- Bug #1517388: sqlite3.dll is now installed on Windows independent
1611 of Tcl/Tk.
1612
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001613- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001614 trying to be installed even though it's empty.

1626 documentation for the warnings module.
1627
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001628- Patch #1509163: MS Toolkit Compiler no longer available.

1638Core and builtins
1639-----------------
1640
Georg Brandla56b9152006-06-19 06:35:54 +00001641- Patch #1507676: Error messages returned by invalid abstract object operations
1642 (such as iterating over an integer) have been improved and now include the
1643 type of the offending object to help with debugging.
1644
Brett Cannonea3912b2006-06-13 21:46:41 +00001645- Bug #992017: A classic class that defined a __coerce__() method that returned
1646 its arguments swapped would infinitely recurse and segfault the interpreter.
1647
Neal Norwitz909eb122006-06-12 02:13:21 +00001648- Fix the socket tests so they can be run concurrently.
1649
Neal Norwitzb9845e72006-06-12 02:11:18 +00001650- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001651 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001652
Brett Cannon22565aa2006-06-09 22:31:23 +00001653- Bug #532646: object.__call__() will continue looking for the __call__
1654 attribute on objects until one without one is found. This leads to recursion
1655 when you take a class and set its __call__ attribute to an instance of the
1656 class. Originally fixed for classic classes, but this fix is for new-style.
1657 Removes the infinite_rec_3 crasher.
1658
Georg Brandl24250812006-06-09 18:45:48 +00001659- The string and unicode methods startswith() and endswith() now accept
1660 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1661
Brett Cannonde3b0522006-06-08 17:00:45 +00001662- Buffer objects, at the C level, never used the char buffer
1663 implementation even when the char buffer for the wrapped object was
1664 explicitly requested (originally returned the read or write buffer).
1665 Now a TypeError is raised if the char buffer is not present but is
1666 requested.
1667
Georg Brandlddbaa662006-06-04 21:56:52 +00001668- Patch #1346214: Statements like "if 0: suite" are now again optimized
1669 away like they were in Python 2.4.
1670
Georg Brandlb7c8f542006-05-27 12:30:25 +00001671- Builtin exceptions are now full-blown new-style classes instead of
1672 instances pretending to be classes, which speeds up exception handling
1673 by about 80% in comparison to 2.5a2.
1674
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001675- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1676 Unicode 4.1.
1677
Georg Brandlf4ef1162006-05-26 18:03:31 +00001678- Patch #921466: sys.path_importer_cache is now used to cache valid and
1679 invalid file paths for the built-in import machinery which leads to
1680 fewer open calls on startup.
1681
Tim Peters696cf432006-05-24 21:10:40 +00001682- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1683 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1684 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1685 the number of input digits (it was and remains linear-time for bases
1686 2, 4, 8, 16 and 32).
1687
Tim Petersb713ec22006-05-23 18:45:30 +00001688- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1689 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1690 an integer close to ``sys.maxint``. This was repaired by patch
1691 #1335972, which also gives a nice speedup.
1692
Richard Jonescebbefc2006-05-23 18:28:17 +00001693- Patch #1337051: reduced size of frame objects.
1694
1695- PyErr_NewException now accepts a tuple of base classes as its
1696 "base" parameter.
1697
Richard Jones7c88dcc2006-05-23 10:37:38 +00001698- Patch #876206: function call speedup by retaining allocated frame
1699 objects.
1700
Georg Brandl7b90e162006-05-18 07:01:27 +00001701- Bug #1462152: file() now checks more thoroughly for invalid mode
1702 strings and removes a possible "U" before passing the mode to the
1703 C library function.
1704
Neal Norwitz1004a532006-05-15 07:17:23 +00001705- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1706
Neal Norwitz373f0a72006-05-15 07:04:36 +00001707- Bug #1487966: Fix SystemError with conditional expression in assignment
1708
Martin v. Löwis879768d2006-05-11 13:28:43 +00001709- WindowsError now has two error code attributes: errno, which carries
1710 the error values from errno.h, and winerror, which carries the error
1711 values from winerror.h. Previous versions put the winerror.h values
1712 (from GetLastError()) into the errno attribute.
1713
Martin v. Löwis77736712006-05-04 05:51:03 +00001714- Patch #1475845: Raise IndentationError for unexpected indent.
1715
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001716- Patch #1479181: split open() and file() from being aliases for each other.
1717
Tim Peters44bd9862006-06-01 13:49:23 +00001718- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1719 methods were always silently ignored by dictionaries when comparing keys.
1720 They are now passed through (except when using the C API function
1721 ``PyDict_GetItem()``, whose semantics did not change).
1722
1723- Bug #1456209: In some obscure cases it was possible for a class with a
1724 custom ``__eq__()`` method to confuse dict internals when class instances
1725 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1726 No, you don't have any code that did this ;-)

1729-----------------
1730
Trent Mick960a3f82006-06-28 20:30:41 +00001731- Bug #1295808: expat symbols should be namespaced in pyexpat
1732
1733- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1734
Brett Cannon6ee7d012006-06-08 16:23:04 +00001735- Change binascii.hexlify to accept a read-only buffer instead of only a char
1736 buffer and actually follow its documentation.
1737
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001738- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1739
Nick Coghlanc649ec52006-05-29 12:43:05 +00001740- Patch #1478788 (modified version): The functional extension module has
1741 been renamed to _functools and a functools Python wrapper module added.
1742 This provides a home for additional function related utilities that are
1743 not specifically about functional programming. See PEP 309.
1744
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001745- Patch #1493701: performance enhancements for struct module.
1746
Georg Brandl378d5922006-05-17 14:26:50 +00001747- Patch #1490224: time.altzone is now set correctly on Cygwin.
1748
Georg Brandl8d3342b2006-05-16 07:38:27 +00001749- Patch #1435422: zlib's compress and decompress objects now have a
1750 copy() method.
1751
Andrew MacIntyre92913322006-06-13 15:04:24 +00001752- Patch #1454481: thread stack size is now tunable at runtime for thread
1753 enabled builds on Windows and systems with Posix threads support.
1754
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001755- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1756 (up to the system limit of 32K characters).
1757
1758- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1759 As a result, these functions now raise WindowsError instead of OSError.
1760
Tim Peters7a822da2006-05-25 21:50:17 +00001761- ``time.clock()`` on Win64 should use the high-performance Windows
1762 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1763 Windows platforms).
1764
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001765- Calling Tk_Init twice is refused if the first call failed as that
1766 may deadlock.
1767
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001768- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1769 accept it without potentially using an uninitialized pointer.
1770
1771- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1772 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

1777
Gregory P. Smith372b5832006-06-05 18:48:21 +00001778- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1779 parameter is supplied. [SF pybsddb bug #1477863]
1780
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001781- bsddb: the __len__ method of a DB object has been fixed to return correct
1782 results. It could previously incorrectly return 0 in some cases.
1783 Fixes SF bug 1493322 (pybsddb bug 1184012).
1784
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001785- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1786 aborts the db transaction safely when a modifier callback fails.
1787 Fixes SF python patch/bug #1408584.
1788
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001789- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001790 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001791 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1792 database calls that would previously deadlock. [SF python bug #775414]

1823
Tim Peters43898b42006-06-14 04:09:25 +00001824- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1825 guarantee that adjacent triples in the return list always describe
1826 non-adjacent blocks. Previously, a pair of matching blocks could end
1827 up being described by multiple adjacent triples that formed a partition
1828 of the matching pair.

1837
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001838- The wsgiref package has been added to the standard library.
1839
Nick Coghlan676725d2006-06-08 13:54:49 +00001840- The functions update_wrapper() and wraps() have been added to the functools
1841 module. These make it easier to copy relevant metadata from the original
1842 function when writing wrapper functions.
1843
Tim Petersd6a9eef2006-06-05 01:48:21 +00001844- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1845 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001846
Martin v. Löwis3f767792006-06-04 19:36:28 +00001847- Patch #1359618: Speed up charmap encoder by using a trie structure
1848 for lookup.
1849
Tim Petersd609b1a2006-06-02 23:22:51 +00001850- The functions in the ``pprint`` module now sort dictionaries by key
1851 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1852 if and only if its display required more than one line, although that
1853 wasn't documented. The new behavior increases predictability; e.g.,
1854 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.

Georg Brandlb89316f2006-05-17 15:51:16 +00001866- Patch #1180296: Two new functions were added to the locale module:
1867 format_string() to get the effect of "format % items" but locale-aware,
1868 and currency() to format a monetary number with currency sign.

1881 a couple of issues, notably handling of long file names using the
1882 GNU LONGNAME extension.
1883
1884- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1885 new flag when ``name`` is already the name of an option flag.
1886
1887- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1888 package.
1889
1890- Patch #1472854: make the rlcompleter.Completer class usable on non-
1891 UNIX platforms.

1932-----------------
1933
Thomas Heller1b046642006-04-18 18:51:06 +00001934- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1935 by converting these apis from macros into exported functions again:
1936
1937 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1938 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1939 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne

1942
Martin v. Löwis45294a92006-04-18 06:24:08 +00001943- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1944
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001945- All uses of PyStructSequence_InitType have been changed to initialize
1946 the type objects only once, even if the interpreter is initialized
1947 multiple times.
1948
Neal Norwitz61546162006-04-14 05:20:28 +00001949- Bug #1454485, array.array('u') could crash the interpreter. This was
1950 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1951 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1952
1953- Py_UNICODE is unsigned. It was always documented as unsigned, but
1954 due to a bug had a signed value in previous versions.
1955
Tim Peters3a5e8b12006-04-11 01:44:07 +00001956- Patch #837242: ``id()`` of any Python object always gives a positive
1957 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1958 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001959 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001960 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001961
Tim Peters3a5e8b12006-04-11 01:44:07 +00001962 def __hash__(self):
1963 return id(self) # WRONG
1964
1965 because a hash result must be a (short) Python int but it was always
1966 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001967 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001968 was always usable as a hash value before this patch. That's no longer
1969 necessarily so.
1970
1971- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001972 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001973 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001974 #1454844)
1975
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001976- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1977 involving generators that have paused outside of any ``try`` or ``with``
1978 blocks. (In 2.5a1, a paused generator that was part of a reference
1979 cycle could not be garbage collected, regardless of whether it was
1980 paused in a ``try`` or ``with`` block.)

2014 or exception is ignored).
2015
Nick Coghlanda2268f2006-04-24 04:37:15 +00002016- Fixed contextlib.nested to cope with exceptions being raised and
2017 caught inside exit handlers.
2018
Greg Wardab05edc2006-04-23 03:47:58 +00002019- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2020 hex, octal, or binary; add ``append_const`` action; keep going if
2021 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2022 added ``epilog`` for better help generation).
2023
Tim Peters21fbd572006-04-21 21:18:10 +00002024- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2025 called from a thread spawned as a side effect of importing a module.
2026
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002027- The pydoc module now supports documenting packages contained in
2028 .zip or .egg files.
2029
2030- The pkgutil module now has several new utility functions, such
2031 as ``walk_packages()`` to support working with packages that are either
2032 in the filesystem or zip files.
2033
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002034- The mailbox module can now modify and delete messages from
2035 mailboxes, in addition to simply reading them. Thanks to Gregory
2036 K. Johnson for writing the code, and to the 2005 Google Summer of
2037 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002038
Tim Petersc7605f22006-04-17 21:12:33 +00002039- The ``__del__`` method of class ``local`` in module ``_threading_local``
2040 returned before accomplishing any of its intended cleanup.
2041
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002042- Patch #790710: Add breakpoint command lists in pdb.

Martin v. Löwisc90b17e2006-04-15 08:13:05 +00002073- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002074
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002075- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2076 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002077 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002078 CXX from --with-cxx-main, see description in README.
2079
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002080- Patch #1429775: Link extension modules with the shared libpython.
2081
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002082- Fixed a libffi build problem on MIPS systems.
2083
Tim Peters8931ff12006-05-13 23:28:20 +00002084- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2085 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2086 and "%zu" for unsigned integers of type ``size_t``.
2087
Anthony Baxter51bcb682006-04-05 14:51:42 +00002088Tests
2089-----
2090
Nick Coghlanda2268f2006-04-24 04:37:15 +00002091- test_contextlib now checks contextlib.nested can cope with exceptions
2092 being raised and caught inside exit handlers.
2093
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002094- test_cmd_line now checks operation of the -m and -c command switches
2095
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002096- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2097 it separately and by hand. It also wasn't cleaning up its changes to
2098 the current Decimal context.
2099
Thomas Woutersabd08882006-04-26 15:53:30 +00002100- regrtest.py now has a -M option to run tests that test the new limits of
2101 containers, on 64-bit architectures. Running these tests is only sensible
2102 on 64-bit machines with more than two gigabytes of memory. The argument
2103 passed is the maximum amount of memory for the tests to use.
2104
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00002105Tools

2107
2108- Added the Python benchmark suite pybench to the Tools/ directory;
2109 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +00002111Documentation
2112-------------
2113
Tim Petersb06d28c2006-05-12 01:57:59 +00002114- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2115
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002116- PEP 343: Added Context Types section to the library reference
2117 and attempted to bring other PEP 343 related documentation into
2118 line with the implementation and/or python-dev discussions.
2119
Tim Peters8dc73d22006-04-24 02:03:16 +00002120- Bug #1337990: clarified that ``doctest`` does not support examples
2121 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002124What's New in Python 2.5 alpha 1?
2125=================================
2126
Anthony Baxterebed3f62006-04-03 15:03:44 +00002127*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002128
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002129Core and builtins
2130-----------------
2131
Nick Coghlan43832302006-04-23 17:04:07 +00002132- PEP 338: -m command line switch now delegates to runpy.run_module
2133 allowing it to support modules in packages and zipfiles
2134
Martin v. Löwisc661b882006-04-20 04:54:23 +00002135- On Windows, .DLL is not an accepted file name extension for
2136 extension modules anymore; extensions are only found if they
2137 end in .PYD.
2138
Martin v. Löwisea62d252006-04-03 10:56:49 +00002139- Bug #1421664: sys.stderr.encoding is now set to the same value as
2140 sys.stdout.encoding.
2141
Neal Norwitz92e212f2006-04-03 04:48:37 +00002142- __import__ accepts keyword arguments.
2143
Georg Brandlccadf842006-03-31 18:54:53 +00002144- Patch #1460496: round() now accepts keyword arguments.
2145
Anthony Baxter262c00a2006-03-30 10:53:17 +00002146- Fixed bug #1459029 - unicode reprs were double-escaped.
2147
Hye-Shik Changd478f342006-03-23 12:32:36 +00002148- Patch #1396919: The system scope threads are reenabled on FreeBSD
2149 5.4 and later versions.
2150
Neal Norwitze98ccf62006-03-23 05:39:47 +00002151- Bug #1115379: Compiling a Unicode string with an encoding declaration
2152 now gives a SyntaxError.
2153
Georg Brandlabd1ff82006-03-18 07:59:59 +00002154- Previously, Python code had no easy way to access the contents of a
2155 cell object. Now, a ``cell_contents`` attribute has been added
2156 (closes patch #1170323).
2157
Tim Peterscf79aac2006-03-16 01:14:46 +00002158- Patch #1123430: Python's small-object allocator now returns an arena to
2159 the system ``free()`` when all memory within an arena becomes unused
2160 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2161 freed. Some applications will see a drop in virtual memory size now,
2162 especially long-running applications that, from time to time, temporarily
2163 use a large number of small objects. Note that when Python returns an
2164 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002165 platform C library will in turn return that memory to the operating system.
2166 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002167 appears to be effective at least on Microsoft C and gcc-based systems.
2168 Thanks to Evan Jones for hard work and patience.
2169
Georg Brandl533ff6f2006-03-08 18:09:27 +00002170- Patch #1434038: property() now uses the getter's docstring if there is
2171 no "doc" argument given. This makes it possible to legitimately use
2172 property() as a decorator to produce a read-only property.
2173
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002174- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2175 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2176 of requiring an int or long in slicing and a few other contexts, enabling
2177 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2178
Neal Norwitz995acdf2006-03-07 05:01:00 +00002179- Fixed various bugs reported by Coverity's Prevent tool.
2180
Brett Cannonbf364092006-03-01 04:25:17 +00002181- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2182 new exception base class, BaseException, which has a new message attribute.
2183 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2184 Raising a string exception now raises a DeprecationWarning.
2185
Thomas Woutersfb609f42006-02-28 16:37:25 +00002186- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2187 explicitly relative, using 'from .module import name' to mean 'from the same
2188 package as this module is in. Imports without dots still default to the
2189 old relative-then-absolute, unless 'from __future__ import
2190 absolute_import' is used.
2191
Brett Cannona7446e32006-02-27 23:39:10 +00002192- Properly check if 'warnings' raises an exception (usually when a filter set
2193 to "error" is triggered) when raising a warning for raising string
2194 exceptions.
2195
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002196- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002197 The name was removed from Include/code.h.
2198
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002199- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002200
Guido van Rossum1968ad32006-02-25 22:38:04 +00002201- Patch 1433928:
2202 - The copy module now "copies" function objects (as atomic objects).
2203 - dict.__getitem__ now looks for a __missing__ hook before raising
2204 KeyError.
2205
Tim Peters84ef21c2006-02-28 20:39:06 +00002206- PEP 343: with statement implemented. Needs ``from __future__ import
2207 with_statement``. Use of 'with' as a variable will generate a warning.
2208 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002209 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002210 The following objects have __context__ methods:
2211 - The built-in file type.
2212 - The thread.LockType type.
2213 - The following types defined by the threading module:
2214 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2215 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002216
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002217- Fix the encodings package codec search function to only search
2218 inside its own package. Fixes problem reported in patch #1433198.
2219
2220 Note: Codec packages should implement and register their own
2221 codec search function. PEP 100 has the details.
2222
Tim Peters9ea89d22006-06-04 03:26:02 +00002223- PEP 353: Using ``Py_ssize_t`` as the index type.
2224
2225- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2226 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2227 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2228 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2229 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002230
Neal Norwitzfc76d632006-01-10 06:03:13 +00002231- Patch #1400181, fix unicode string formatting to not use the locale.
2232 This is how string objects work. u'%f' could use , instead of .
2233 for the decimal point. Now both strings and unicode always use periods.
2234
Neal Norwitz671b9e32006-01-09 07:07:12 +00002235- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2236 configure would break checking curses.h.
2237
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002238- Bug #959576: The pwd module is now builtin. This allows Python to be
2239 built on UNIX platforms without $HOME set.
2240
Neal Norwitzc10978f2005-12-19 06:07:16 +00002241- Bug #1072182, fix some potential problems if characters are signed.
2242
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002243- Bug #889500, fix line number on SyntaxWarning for global declarations.
2244
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002245- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2246
Neal Norwitze7214a12005-12-18 05:03:17 +00002247- Support for converting hex strings to floats no longer works.
2248 This was not portable. float('0x3') now raises a ValueError.
2249
Barry Warsaw2a38a862005-12-18 01:27:35 +00002250- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002251 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002252 is now displayed in interactive prompt banner.
2253
Georg Brandlfa166682005-12-17 21:45:17 +00002254- Implementation of PEP 341 - Unification of try/except and try/finally.
2255 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002256 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002257
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002258- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2259 now encodes backslash correctly.
2260
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002261- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2262
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002263- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002264 and long longs.
2265
Neal Norwitz67715f02005-11-09 06:59:35 +00002266- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002267 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002268 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002269
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002270- Replaced most Unicode charmap codecs with new ones using the
2271 new Unicode translate string feature in the builtin charmap
2272 codec; the codecs were created from the mapping tables available
2273 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2274 encodings now include a mapping for the Apple logo)
2275
Tim Peterse3547fd2005-12-16 23:13:57 +00002276- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002277
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002278- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002279
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002280- A new AST parser implementation was completed. The abstract
2281 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002282 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002283
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002284- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002285 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2286
Neal Norwitz708e51a2005-10-03 04:48:15 +00002287- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2288
Neal Norwitz11bd1192005-10-03 00:54:56 +00002289- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2290 Provide a warning when a directory is passed on the command line.
2291
Neal Norwitz40d37812005-10-02 01:48:49 +00002292- Fix segfault with invalid coding.
2293
2294- SF bug #772896: unknown encoding results in MemoryError.
2295
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002296- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002297 supported a __len__() method which evaluated to False when the iterator
2298 was empty.
2299
Guido van Rossum630db602005-09-20 18:49:54 +00002300- On 64-bit platforms, when __len__() returns a value that cannot be
2301 represented as a C int, raise OverflowError.
2302
Skip Montanarof8948ca2005-09-19 03:54:46 +00002303- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002304 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002305
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002306- SF bug #893549: parsing keyword arguments was broken with a few format
2307 codes.
2308
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002309- Changes donated by Elemental Security to make it work on AIX 5.3
2310 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2311 bug #105470: test_pwd fails on 64bit system (Opteron).
2312
Guido van Rossum539c6622005-09-14 17:49:54 +00002313- Changes donated by Elemental Security to make it work on HP-UX 11 on
2314 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2315
Georg Brandl4550b8d2005-08-26 06:43:52 +00002316- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002317 (fixes bug #1119418).
2318
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002319- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2320
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002321- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2322 exceptions that cause a function to exit.
2323
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002324- The implementation of set() and frozenset() was revised to use its
2325 own internal data structure. Memory consumption is reduced by 1/3
2326 and there are modest speed-ups as well. The API is unchanged.
2327
Tim Petersde7990b2005-07-17 23:45:23 +00002328- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2329
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002330- SF bug #1229429: PyObject_CallMethod failed to decrement some
2331 reference counts in some error exit cases.
2332
Tim Petersecc6e6a2005-07-10 22:30:55 +00002333- SF bug #1185883: Python's small-object memory allocator took over
2334 a block managed by the platform C library whenever a realloc specified
2335 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002336 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002337 portable way to copy data from the C-managed block into Python's
2338 small-object space without risking a memory fault. Python's small-object
2339 realloc now leaves such blocks under the control of the platform C
2340 realloc.

Michael W. Hudsonb8963812005-07-05 15:21:58 +00002342- SF bug #1232517: An overflow error was not detected properly when
2343 attempting to convert a large float to an int in os.utime().
2344
Raymond Hettinger3296e692005-06-29 23:29:56 +00002345- SF bug #1224347: hex longs now print with lowercase letters just
2346 like their int counterparts.
2347
Michael W. Hudson188d4362005-06-20 16:52:57 +00002348- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2349 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2350 interpreter states; back out that fix and do a better job (see
2351 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2352 for a longer write-up of the problem).
2353
Michael W. Hudsondf888462005-06-03 14:41:55 +00002354- SF patch #1180995: marshal now uses a binary format by default when
2355 serializing floats.
2356
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002357- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2358 the routines that promise to produce IEEE 754 binary representations
2359 of floats now simply copy bytes around.
2360
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002361- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2362 278.
2363
Brett Cannonc3647ac2005-04-26 03:45:26 +00002364- patch #1109424: int, long, float, complex, and unicode now check for the
2365 proper magic slot for type conversions when subclassed. Previously the
2366 magic slot was ignored during conversion. Semantics now match the way
2367 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002368 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002369 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002370 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002371
Barry Warsawc8d907c2005-04-19 23:43:40 +00002372- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2373 NULL, now raise an AttributeError when attempting to set or delete the
2374 attribute. Previously a TypeError was raised, but this was inconsistent
2375 with the equivalent pure-Python implementation.
2376
Michael W. Hudson774479c2005-04-18 08:46:17 +00002377- It is now safe to call PyGILState_Release() before
2378 PyEval_InitThreads() (note that if there is reason to believe there
2379 are multiple threads around you still must call PyEval_InitThreads()
2380 before using the Python API; this fix is for extension modules that
2381 have no way of knowing if Python is multi-threaded yet).
2382
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002383- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2384 disabled caused a crash.
2385
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002386- Bug #1165306: instancemethod_new allowed the creation of a method
2387 with im_class == im_self == NULL, which caused a crash when called.
2388
Tim Petersecc6e6a2005-07-10 22:30:55 +00002389- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002390 fixes the crash seen in bug #1165761
2391
Raymond Hettinger96229b12005-03-11 06:49:40 +00002392- Added two new builtins, any() and all().
2393
Brett Cannon409d8f22005-03-05 06:47:57 +00002394- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002395 (e.g., ``class C(): pass`` is no longer a syntax error).
2396 Patch #1176012 added support to the 'parser' module and 'compiler' package
2397 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002398
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002399- Patch #1115086: Support PY_LONGLONG in structmember.
2400
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002401- Bug #1155938: new style classes did not check that __init__() was
2402 returning None.
2403
Tim Petersecc6e6a2005-07-10 22:30:55 +00002404- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002405 ('\') with a specific error message.
2406
Martin v. Löwisff232d72005-03-03 09:24:38 +00002407- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2408
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002409- Bug #1124295: the __name__ attribute of file objects was
2410 inadvertently made inaccessible in restricted mode.
2411
Tim Petersecc6e6a2005-07-10 22:30:55 +00002412- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002413 an ferror() call.
2414
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002415- min() and max() now support key= arguments with the same meaning as in
2416 list.sort().
2417
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002418- The peephole optimizer now performs simple constant folding in expressions:
2419 (2+3) --> (5).
2420
Raymond Hettingera422c342005-01-11 03:03:27 +00002421- set and frozenset objects can now be marshalled. SF #1098985.
2422
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002423- Bug #1077106: Poor argument checking could cause memory corruption
2424 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002425
Jeremy Hyltonab630502005-02-04 18:44:06 +00002426- The parser did not complain about future statements in illegal
2427 positions. It once again reports a syntax error if a future
2428 statement occurs after anything other than a doc string.
2429
Neil Schemenauercf52c072005-08-12 17:34:58 +00002430- Change the %s format specifier for str objects so that it returns a
2431 unicode instance if the argument is not an instance of basestring and
2432 calling __str__ on the argument returns a unicode instance.
2433
Tim Petersf4e69282006-02-27 17:15:31 +00002434- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2435 current thread state when the auto-GIL-state machinery knows about
2436 it (since the thread state is being deleted, continuing to remember it
2437 can't help, but can hurt if another thread happens to get created with
2438 the same thread id).
2439
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002440Extension Modules

2457
2458- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2459
2460- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002461 is deprecated. The undocumented re.engine variable no longer exists.
2462

2465
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002466- The unicodedata module was updated to the 4.1 version of the Unicode
2467 database. The 3.2 version is still available as unicodedata.db_3_2_0
2468 for applications that require this specific version (such as IDNA).
2469
Neal Norwitzb62c4332006-03-04 18:35:47 +00002470- The timing module is no longer built by default. It was deprecated
2471 in PEP 4 in Python 2.0 or earlier.
2472
Guido van Rossum1968ad32006-02-25 22:38:04 +00002473- Patch 1433928: Added a new type, defaultdict, to the collections module.

2475
Georg Brandldbd83392006-02-20 09:42:33 +00002476- Bug #854823: socketmodule now builds on Sun platforms even when

2491
Martin v. Löwis14694662006-02-03 12:54:16 +00002492- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2493 are reported, the limit on path name lengths is removed, and stat reports
2494 WindowsError now (instead of OSError).
2495
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002496- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

2571 the request code argument, which results in more C-like behaviour
2572 for large or negative values.
2573
Tim Petersecc6e6a2005-07-10 22:30:55 +00002574- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

2615 args tuple returned by __reduce__().
2616
Raymond Hettingerb2594052004-12-05 09:25:51 +00002617- itertools.islice() now accepts None for the start and step arguments.

Tim Peters112aad32006-07-19 00:03:19 +00002629
Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002630- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2631 been renamed to have only a single underscore prefix. This was done to
2632 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002633
Nick Coghlan43832302006-04-23 17:04:07 +00002634- PEP 338: new module runpy defines a run_module function to support
2635 executing modules which provide access to source code or a code object
2636 via the PEP 302 import mechanisms.
2637
Anthony Baxter93f5b932006-04-03 08:05:07 +00002638- The email module's parsedate_tz function now sets the daylight savings

2646 in attribute values.
2647
Anthony Baxterc51ee692006-04-01 00:57:31 +00002648- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002649 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002650 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002651 module will not be built.
2652
Tim Petersc17976e2006-04-01 00:26:53 +00002653- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2654 aren't officially supported here, and trying to use them will probably
2655 raise an exception some day. But dicts have been allowed, and "mostly
2656 worked", so support for them won't go away without warning.
2657
Georg Brandl338ef7d2006-03-31 18:42:16 +00002658- Bug #1445068: getpass.getpass() can now be given an explicit stream
2659 argument to specify where to write the prompt.
2660
Georg Brandl22ec80b2006-03-31 18:25:44 +00002661- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2670 to make it easier to monitor when daemon threads have completed
2671 processing all enqueued tasks. Patch #1455676.
2672
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002673- popen2.Popen objects now preserve the command in a .cmd attribute.

2676
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002677- email 4.0 package now integrated. This is largely the same as the email 3.0
2678 package that was included in Python 2.3, except that PEP 8 module names are
2679 now used (e.g. mail.message instead of email.Message). The MIME classes
2680 have been moved to a subpackage (e.g. email.mime.text instead of
2681 email.MIMEText). The old names are still supported for now. Several
2682 deprecated Message methods have been removed and lots of bugs have been
2683 fixed. More details can be found in the email package documentation.
2684
Walter Dörwald40108c92006-03-27 08:15:44 +00002685- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2686 (a subclass of tuple) that provides incremental decoders and encoders
2687 (a way to use stateful codecs without the stream API). Python functions
2688 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2689 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2690 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002691
Walter Dörwald067db482006-03-15 22:17:27 +00002692- Patch #1359365: Calling next() on a closed StringIO.String object raises
2693 a ValueError instead of a StopIteration now (like file and cString.String do).
2694 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2695 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002696
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002697- A regrtest option -w was added to re-run failed tests in verbose mode.

Martin v. Löwis3e865952006-01-24 15:51:21 +00002745 specifications, raises IOErrors when proxies for unsupported protocols
2746 are defined, and uses the https proxy on https redirections.

2770 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2771 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2772 Ronald L. Rivest offered this advice for Python:
2773
2774 "The consensus of researchers in this area (at least as
2775 expressed at the NIST Hash Function Workshop 10/31/05),
2776 is that SHA-256 is a good choice for the time being, but
2777 that research should continue, and other alternatives may
2778 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002779
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002780- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandl5284b532005-06-26 22:54:58 +00002864
Georg Brandl2f210b62005-06-26 22:09:06 +00002865- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
2866
Georg Brandlfbff1bc2005-06-26 21:36:25 +00002867- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
2868 error messages.
2869
Georg Brandl379f99d2005-06-26 21:09:38 +00002870- Bug #1108948: Cookie.py produced invalid JavaScript code.
2871
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00002872- The tokenize module now detects and reports indentation errors.
2873 Bug #1224621.
2874
Raymond Hettinger68c04532005-06-10 11:05:19 +00002875- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002876 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002877 the generate_tokens() function now accepts a callable argument that
2878 terminates by raising StopIteration.
2879
Georg Brandl9166e1a2005-06-04 09:20:03 +00002880- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2881
Georg Brandl268e61c2005-06-03 14:28:50 +00002882- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2883 component of the path.
2884
Skip Montanaro174dd222005-05-14 20:54:16 +00002885- Patch #1120353: The xmlrpclib module provides better, more transparent,
2886 support for datetime.{datetime,date,time} objects. With use_datetime set
2887 to True, applications shouldn't have to fiddle with the DateTime wrapper
2888 class at all.
2889
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002890- distutils.commands.upload was added to support uploading distribution
2891 files to PyPI.
2892
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002893- distutils.commands.register now encodes the data as UTF-8 before posting
2894 them to PyPI.
2895
Raymond Hettinger267b8682005-03-27 10:47:39 +00002896- decimal operator and comparison methods now return NotImplemented
2897 instead of raising a TypeError when interacting with other types. This
2898 allows other classes to implement __radd__ style methods and have them
2899 work as expected.
2900
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002901- Bug #1163325: Decimal infinities failed to hash. Attempting to
2902 hash a NaN raised an InvalidOperation instead of a TypeError.
2903
Tim Petersecc6e6a2005-07-10 22:30:55 +00002904- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002905 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2906

Raymond Hettingerbab41432005-02-05 01:31:19 +00002937- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2938
Guido van Rossumd0641422005-02-03 15:01:24 +00002939- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2940 disables recursive traversal through instance attributes, which can
2941 be exploited in various ways.
2942
Tim Peterse3547fd2005-12-16 23:13:57 +00002943- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002944 flags on the HTTP listening socket.
2945
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002946- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2947 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2948
Fred Drakefbdeaad2006-07-29 16:56:15 +00002949- Patches #893642, #1039083: add allow_none, encoding arguments to
2950 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002951
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002952- Bug #1110478: Revert os.environ.update to do putenv again.
2953
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002954- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2955
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002956- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2957
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002958- Enhancements to the csv module:
2959
2960 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002961 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002962 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002963 + Dialect parameter parsing has been re-implemented to improve error
2964 reporting.
2965 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2966 dictates.
2967 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002968 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002969 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002970 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2971 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002972 + reader now allows \r characters to be quoted (previously it only allowed
2973 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002974 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002975 + Dialect classes passed to the module are no longer instantiated by
2976 the module before being parsed (the former validation scheme required
2977 this, but the mechanism was unreliable).
2978 + The dialect registry now contains instances of the internal
2979 C-coded dialect type, rather than references to python objects.
2980 + the internal c-coded dialect type is now immutable.
2981 + register_dialect now accepts the same keyword dialect specifications
2982 as the reader and writer, allowing the user to register dialects
2983 without first creating a dialect class.
2984 + a configurable limit to the size of parsed fields has been added -
2985 previously, an unmatched quote character could result in the entire
2986 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002987 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002988 the parser field size limit (returning the former limit). The initial
2989 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002990 + A line_num attribute has been added to the reader object, which tracks
2991 the number of lines read from the source iterator. This is not
2992 the same as the number of records returned, as records can span
2993 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002994 + reader and writer objects were not being registered with the cyclic-GC.
2995 This has been fixed.
2996
Brett Cannone6539c42005-01-08 02:43:53 +00002997- _DummyThread objects in the threading module now delete self.__block that is
2998 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2999 lock primitives tend to be limited in number and thus should not be wasted on
3000 a _DummyThread object. Fixes bug #1089632.
3001
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003002- The imghdr module now detects Exif files.
3003
Raymond Hettinger6065d322004-12-20 23:51:53 +00003004- StringIO.truncate() now correctly adjusts the size attribute.
3005 (Bug #951915).
3006
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003007- locale.py now uses an updated locale alias table (built using
3008 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3009 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003010 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003011
Raymond Hettinger3557f422004-12-07 12:02:02 +00003012- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3013
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003014- the pickle module no longer accepts the deprecated None option in the
3015 args tuple returned by __reduce__().
3016
Brett Cannon84667c02004-12-07 03:25:18 +00003017- optparse now optionally imports gettext. This allows its use in setup.py.
3018
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003019- the pickle module no longer uses the deprecated bin parameter.
3020
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003021- the shelve module no longer uses the deprecated binary parameter.
3022
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003023- the pstats module no longer uses the deprecated ignore() method.
3024
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003025- the filecmp module no longer uses the deprecated use_statcache argument.
3026
Raymond Hettinger664347b2004-12-04 21:21:53 +00003027- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3028 extended or overridden by subclasses. Formerly, the subclassed method would
3029 be ignored by the rest of the module. (Bug #1078905).
3030
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003031- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003032 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003033
Walter Dörwald36733692004-12-22 12:50:50 +00003034- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3035 once when a size argument is given. This prevents a buffer overflow in the
3036 tokenizer with very long source lines.
3037
Barry Warsaw538561e2006-01-01 21:48:54 +00003038- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3039 immediately after creating the object, without any intervening
3040 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003041
Skip Montanaro05885812005-01-16 20:48:27 +00003042- The reconvert.quote function can now emit triple-quoted strings. The
3043 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003044
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003045- ``UserString.MutableString`` now supports negative indices in
3046 ``__setitem__`` and ``__delitem__``
3047
Greg Ward40407942005-03-05 02:53:17 +00003048- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3049 correctly.
3050
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003051- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3052 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3053 character even if the user has passed a size parameter to get a proper
3054 line ending. Remove the special handling of a "\r\n" that has been split
3055 between two lines.
3056
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003057- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3058 about illegal code points. The codec now supports PEP 293 style error
3059 handlers.
3060
Walter Dörwald78a78b02005-09-01 12:04:29 +00003061- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003062 from the input stream, so that the output is a byte string in the correct
3063 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003064
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003065- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3066 considering it exactly like a '*'.
3067
Walter Dörwald007f8df2005-10-09 19:42:27 +00003068- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3069 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003070
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003071- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3072
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003073- Patch #1413711: Certain patterns of differences were making difflib
3074 touch the recursion limit.
3075
Walter Dörwald58917a62006-03-31 15:26:22 +00003076- Bug #947906: An object oriented interface has been added to the calendar
3077 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003078 called as a script (e.g. via ``python -mcalendar``). Localized month and
3079 weekday names can be ouput (even if an exotic encoding is used) using
3080 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003081

3100
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003101- Bug #1189330: configure did not correctly determine the necessary
3102 value of LINKCC if python was built with GCC 4.0.
3103
Trent Mick8321b422005-07-26 02:29:21 +00003104- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3105 vulnerability in zlib 1.2.1 and 1.2.2.
3106
Brett Cannon08cd5982005-04-24 22:26:38 +00003107- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3108 flags that change binary compatibility. Changes were also made to
3109 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003110 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003111
Bob Ippolitoed233462005-03-29 13:47:59 +00003112- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3113 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3114 no longer exists). This configure patch makes things right.
3115
Martin v. Löwise2713be2005-03-08 15:03:08 +00003116- Bug #1158607: Build with --disable-unicode again.
3117
Brett Cannon46d96232005-02-16 00:07:19 +00003118- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3119 defined. Discovered as a result of not being able to build on OS X.
3120
Brett Cannon516592f2004-12-07 00:42:59 +00003121- setup.py now uses the directories specified in LDFLAGS using the -L option
3122 and in CPPFLAGS using the -I option for adding library and include
3123 directories, respectively, for compiling extension modules against. This has
3124 led to the core being compiled using the values in CPPFLAGS. It also removes
3125 the need for the special-casing of both DarwinPorts and Fink for darwin since
3126 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3127 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3128 Fink, ``-I/opt/local/include`` for DarwinPorts).

Brett Cannon43802422005-02-10 20:48:03 +00003130- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3131 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3132 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3133 Closes bug #1096244. Thanks Gregory Bond.

3136-----
3137
Tim Petersc9d78aa2006-03-26 23:27:58 +00003138- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3139 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3140 is obtained via the ``PyObject_`` family, it must be released via the
3141 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3142 always been officially true, but when Python's small-object allocator was
3143 introduced, an attempt was made to cater to a few extension modules
3144 discovered at the time that obtained memory via ``PyObject_New`` but
3145 released it via ``PyMem_DEL``. It's years later, and if such code still
3146 exists it will fail now (probably with segfaults, but calling wrong
3147 low-level memory management functions can yield many symptoms).
3148
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003149- Added a C API for set and frozenset objects.

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003153- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3154 mapping argument now. This string is used as a mapping table. Byte values
3155 greater than the length of the string and 0xFFFE are treated as undefined
3156 mappings.
