15- Issue #1477: With narrow Unicode builds, the unicode escape sequence
16 \Uxxxxxxxx did not accept values outside the Basic Multilingual Plane. This
17 affected raw unicode literals and the 'raw-unicode-escape' codec. Now
18 UTF-16 surrogates are generated in this case, like normal unicode literals
19 and the 'unicode-escape' codec.
20
Neal Norwitzb3635f92008-03-18 04:17:36 +000021- Issue #2321: use pymalloc for unicode object string data to reduce
22 memory usage in some circumstances.

32 incorrect python code.
33
Mark Dickinsonbfdbfd42008-03-25 18:58:13 +000034- Issue #2482: Make sure that the coefficient of a Decimal is always
35 stored as a str instance, not as a unicode instance. This ensures
36 that str(Decimal) is always an instance of str. This fixes a
37 regression from Python 2.5.1 to Python 2.5.2.

930-----------------
931
Neal Norwitz0bcafac2006-09-11 08:51:17 +0000932- Make _PyGILState_NoteThreadState() static, it was not used anywhere
933 outside of pystate.c and should not be necessary.
934
Brett Cannon19d76c52006-09-09 07:18:44 +0000935- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
936 allows calling unicode() on exceptions classes directly to succeed.
937
Georg Brandlecab6232006-09-06 06:47:02 +0000938- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
939 Also make sure that every exception class has __module__ set to
940 'exceptions'.
941
Georg Brandl37a9e572006-09-06 06:09:34 +0000942- Bug #1550983: emit better error messages for erroneous relative

952
Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000953- The return tuple from str.rpartition(sep) is (tail, sep, head) where
954 head is the original string if sep was not found.
955
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000956- Bug #1520864: unpacking singleton tuples in list comprehensions and
957 generator expressions (x for x, in ... ) works again. Fixing this problem
958 required changing the .pyc magic number. This means that .pyc files
959 generated before 2.5c2 will be regenerated.

1072-----------------
1073
Neal Norwitz24b6f202006-09-05 04:43:56 +00001074- Fix infinite recursion when subclassing long and overriding __hash__.
1075
1076- Fix concatenation (+=) of long strings.
1077
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001078- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001079 compared equal or unequal to a string and a UnicodeDecodeError
1080 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001081
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001082 Instead, the equal (==) and unequal (!=) comparison operators will
1083 now issue a UnicodeWarning and interpret the two objects as
1084 unequal. The UnicodeWarning can be filtered as desired using
1085 the warning framework, e.g. silenced completely, turned into an
1086 exception, logged, etc.
1087
1088 Note that compare operators other than equal and unequal will still
1089 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001090
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001091- Fix segfault when doing string formatting on subclasses of long.
1092
1093- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1094 with new-style classes.
1095
1096- Fix bug related to __len__ functions returning negative values with
1097 classic classes.
1098
1099- Patch #1538606, Fix __index__() clipping. There were some problems
1100 discovered with the API and how integers that didn't fit into Py_ssize_t
1101 were handled. This patch attempts to provide enough alternatives
1102 to effectively use __index__.
1103
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001104- Bug #1536021: __hash__ may now return long int; the final hash
1105 value is obtained by invoking hash on the long int.
1106
Thomas Hellerab1049c2006-08-08 17:37:00 +00001107- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1108
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001109- Bug #1535165: fixed a segfault in input() and raw_input() when
1110 sys.stdin is closed.
1111
Thomas Heller74d36f02006-08-04 18:17:40 +00001112- On Windows, the PyErr_Warn function is now exported from
1113 the Python dll again.
1114
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001115- Bug #1191458: tracing over for loops now produces a line event
1116 on each iteration. Fixing this problem required changing the .pyc
1117 magic number. This means that .pyc files generated before 2.5c1
1118 will be regenerated.
1119
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001120- Bug #1333982: string/number constants were inappropriately stored
1121 in the byte code and co_consts even if they were not used, ie
1122 immediately popped off the stack.
1123
Georg Brandle9462c72006-08-04 18:03:37 +00001124- Fixed a reference-counting problem in property().

1128-------
1129
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001130- Fix a bug in the ``compiler`` package that caused invalid code to be
1131 generated for generator expressions.
1132
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001133- The distutils version has been changed to 2.5.0. The change to
1134 keep it programmatically in sync with the Python version running
1135 the code (introduced in 2.5b3) has been reverted. It will continue
1136 to be maintained manually as static string literal.
1137
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001138- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001139 and this cannot be converted to the required C type, an exception is
1140 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001141 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001142
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001143- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001144 an exception.
1145
Tim Peterscbdd3502006-09-05 01:47:53 +00001146- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001147 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001148 workarounds for clocks with low resolution, to stop the code yielding
1149 duplicate UUIDs.
1150
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001151- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1152 before raising SystemExit, allowing IDLE to honor quit() and exit().
1153
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001154- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1155
Georg Brandl7a1af772006-08-14 21:55:28 +00001156- Patch #1536071: trace.py should now find the full module name of a
1157 file correctly even on Windows.
1158
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001159- logging's atexit hook now runs even if the rest of the module has
1160 already been cleaned up.
1161
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001162- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001163
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001164- Bug #1531405, format_exception no longer raises an exception if
1165 str(exception) raised an exception.
1166
Neil Schemenauer06ded092006-08-04 16:20:30 +00001167- Fix a bug in the ``compiler`` package that caused invalid code to be
1168 generated for nested functions.

1180
Thomas Heller1ce433e2006-08-14 16:20:04 +00001181- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The

1183
Thomas Heller86720042006-08-14 11:17:48 +00001184- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1185 uses the _as_parameter_ attribute when objects are passed to foreign
1186 function calls. The ctypes version number was changed to 1.0.1.
1187
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001188- Bug #1530559, struct.pack raises TypeError where it used to convert.
1189 Passing float arguments to struct.pack when integers are expected
1190 now triggers a DeprecationWarning.

1240Core and builtins
1241-----------------
1242
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001243- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001244 returned a long (see PEP 353).
1245
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001246- Bug #1515471: string.replace() accepts character buffers again.
1247
Neal Norwitz07aadb12006-07-30 06:55:48 +00001248- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1249 This provides the proper warning for struct.pack().
1250 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1251
Neal Norwitz0d62a062006-07-30 06:53:31 +00001252- Patch #1531113: Fix augmented assignment with yield expressions.
1253 Also fix a SystemError when trying to assign to yield expressions.
1254
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001255- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1256 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1257 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1258 excessive filesystem operations during imports.
1259
Tim Petersbc24eee2006-07-27 01:14:53 +00001260- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1261 operations on signed longs that are formally undefined by C.
1262 Unfortunately, at least one compiler now cares about that, so complicated
1263 the code to make that compiler happy again.
1264
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001265- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1266
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001267- Patch #1232023: Stop including current directory in search
1268 path on Windows.
1269
Neal Norwitze1fdb322006-07-21 05:32:28 +00001270- Fix some potential crashes found with failmalloc.
1271
Neal Norwitze7563102006-07-17 01:00:16 +00001272- Fix warnings reported by Klocwork's static analysis tool.
1273
Neal Norwitz84be93b2006-07-16 01:50:38 +00001274- Bug #1512814, Fix incorrect lineno's when code within a function
1275 had more than 255 blank lines.
1276
Georg Brandl9dceedb2006-07-12 15:31:17 +00001277- Patch #1521179: Python now accepts the standard options ``--help`` and
1278 ``--version`` as well as ``/?`` on Windows.
1279
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001280- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001281 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001282 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001283
Tim Peters112aad32006-07-19 00:03:19 +00001284- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001285 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001286 new ``sys._current_frames()`` returns a dictionary with one entry,
1287 mapping the faux "thread id" 0 to the current frame.
1288
Ronald Oussoren3075e162006-07-25 20:28:55 +00001289- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

1293-------
1294
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001295- Correction of patch #1455898: In the mbcs decoder, set final=False
1296 for stream decoder, but final=True for the decode function.
1297
Georg Brandl07fec3a2006-08-01 18:49:24 +00001298- os.urandom no longer masks unrelated exceptions like SystemExit or
1299 KeyboardInterrupt.
1300
Tim Peters4643c2f2006-08-10 22:45:34 +00001301- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001302 shutil.copytree on Windows
1303
Georg Brandle34ac7c2006-07-30 11:07:23 +00001304- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1305 refers to file descriptors, not file objects.
1306
Tim Peterscbdd3502006-09-05 01:47:53 +00001307- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001308 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001309 #1513611, and probably others.
1310
Georg Brandledd9b0d2006-07-29 09:33:26 +00001311- Bug #1441397: The compiler module now recognizes module and function
1312 docstrings correctly as it did in Python 2.4.
1313
Tim Peters6f681472006-07-27 23:44:37 +00001314- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1315 lost that tests are sorted by name before being run. This rarely
1316 matters for well-written tests, but can create baffling symptoms if
1317 side effects from one test to the next affect outcomes. ``DocTestFinder``
1318 has been changed to sort the list of tests it returns.
1319
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001320- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001321 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001322
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001323- Bug #978833: Really close underlying socket in _socketobject.close.
1324
Georg Brandldb232dc2006-08-20 13:15:43 +00001325- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1326 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001327
Georg Brandlcf0c1722006-07-26 07:23:32 +00001328- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1329 to recursive calls and call it with the failing package name.
1330
Martin v. Löwis0b483032006-07-25 09:53:12 +00001331- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1332
Georg Brandlc13c34c2006-07-24 14:09:56 +00001333- Patch #1515343: Fix printing of deprecated string exceptions with a
1334 value in the traceback module.
1335
Greg Ward48fae7a2006-07-23 16:05:51 +00001336- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1337
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001338- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1339
Brett Cannoncaebe222006-07-18 04:41:36 +00001340- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1341 argument tuple. For arguments where zero is illegal, the value is forced to
1342 the minimum value that is correct. This is to support an undocumented but
1343 common way people used to fill in inconsequential information in the time
1344 tuple pre-2.4.
1345
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001346- Patch #1220874: Update the binhex module for Mach-O.
1347
Barry Warsawb110bad2006-07-21 14:51:07 +00001348- The email package has improved RFC 2231 support, specifically for
1349 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1350 (name*0=<blah>) parameter continuations. This may change the types of
1351 values returned from email.message.Message.get_param() and friends.
1352 Specifically in some cases where non-encoded continuations were used,
1353 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1354 will just return the string (since non-encoded continuations don't have
1355 charset and language parts).
1356
1357 Also, whereas % values were decoded in all parameter continuations, they are
1358 now only decoded in encoded parameter parts.
1359
Ronald Oussoren3075e162006-07-25 20:28:55 +00001360- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1361
1362- Bug #1517996: IDLE now longer shows the default Tk menu when a
1363 path browser, class browser or debugger is the frontmost window on MacOS X
1364
Barry Warsaw00decd72006-07-27 23:43:15 +00001365- Patch #1520294: Support for getset and member descriptors in types.py,
1366 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1367 of an object against these built-in types and more importantly, for getting
1368 their docstrings printed in the interactive interpreter's help() function.

1372-----------------
1373
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001374- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1375 a socket operation on a socket with a timeout, the exception will be
1376 caught correctly. Previously, the exception was not caught.
1377
Thomas Heller1393d6a2006-07-28 21:43:20 +00001378- Patch #1529514: The _ctypes extension is now compiled on more
1379 openbsd target platforms.
1380
Tim Peters9cab5932006-07-28 00:30:00 +00001381- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1382 a memory leak, affecting pickles and deep copies.
1383
Tim Petersbc24eee2006-07-27 01:14:53 +00001384- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001385 Paul Eggert.
1386
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001387- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1388
Thomas Hellerce049a02006-07-14 17:51:14 +00001389- Patch #1521817: Index range checking on ctypes arrays containing
1390 exactly one element enabled again. This allows iterating over these
1391 arrays, without the need to check the array size before.
1392
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001393- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001394 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001395 /dev/null in certain cases; this is now fixed.
1396
Thomas Heller47d7a062006-07-12 08:43:47 +00001397- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1398 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001399
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001400- Because of a misspelled preprocessor symbol, ctypes was always
1401 compiled without thread support; this is now fixed.
1402
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001403- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1404 methods now allow their database parameter to be None as the
1405 sleepycat API allows.
1406
Matt Flemingec926502006-07-28 11:27:27 +00001407- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1408 bluetooth API compared with Linux and FreeBSD.
1409
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001410Tests

1412
1413- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1414 how long the test file should take to play. Now accepts taking 2.93 secs
1415 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1416
Georg Brandl4793aa32006-07-28 18:31:39 +00001417- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1418 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1419 run via ``regrtest.py``. Now they do.

1429- PythonLauncher now works correctly when the path to the script contains
1430 characters that are treated specially by the shell (such as quotes).
1431
1432- Bug #1527397: PythonLauncher now launches scripts with the working directory
1433 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001434 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001435 expect.

Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001446- Bug #1441486: The literal representation of -(sys.maxint - 1)
1447 again evaluates to a int object, not a long.
1448
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001449- Bug #1501934: The scope of global variables that are locally assigned
1450 using augmented assignment is now correctly determined.
1451
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001452- Bug #927248: Recursive method-wrapper objects can now safely

1454
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001455- Bug #1417699: Reject locale-specific decimal point in float()
1456 and atof().
1457
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001458- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1459 omit a default "error" argument for NULL pointer. This allows
1460 the parser to take a codec from cjkcodecs again.

Neal Norwitzfb48afa2006-07-08 05:31:37 +00001462- Bug #1519018: 'as' is now validated properly in import statements.
1463
Neal Norwitz28746ab2006-07-09 22:14:42 +00001464- On 64 bit systems, int literals that use less than 64 bits are
1465 now ints rather than longs.
1466
Neal Norwitzed657552006-07-10 00:04:44 +00001467- Bug #1512814, Fix incorrect lineno's when code at module scope
1468 started after line 256.
1469
Tim Peters32a83612006-07-10 21:08:24 +00001470- New function ``sys._current_frames()`` returns a dict mapping thread
1471 id to topmost thread stack frame. This is for expert use, and is
1472 especially useful for debugging application deadlocks. The functionality
1473 was previously available in Fazal Majid's ``threadframe`` extension
1474 module, but it wasn't possible to do this in a wholly threadsafe way from
1475 an extension.

1484
Tim Peters32a83612006-07-10 21:08:24 +00001485- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001486 environment variable to be set in order to the SDK environment
1487 for finding the compiler, include files, etc.
1488
Martin v. Löwis388a8c22006-07-06 19:28:03 +00001489- Bug #1515998: Properly generate logical ids for files in bdist_msi.
1490
Nick Coghlan2d792252006-07-06 13:47:18 +00001491- warnings.py now ignores ImportWarning by default
1492
Thomas Woutersadd19112006-07-05 11:03:49 +00001493- string.Template() now correctly handles tuple-values. Previously,
1494 multi-value tuples would raise an exception and single-value tuples would
1495 be treated as the value they contain, instead.
1496
Martin v. Löwisede77f52006-07-03 13:01:35 +00001497- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1498 even if some data are received.
1499
Martin v. Löwis45482392006-07-03 12:28:58 +00001500- Bug #1267547: Put proper recursive setup.py call into the
1501 spec file generated by bdist_rpm.

1504 degrees and radians.
1505
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001506- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001507 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001508
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001509- Bug #1514703: Only setup canvas window in turtle when the canvas
1510 is created.
1511
Martin v. Löwis7596e832006-07-01 15:33:37 +00001512- Bug #1513223: .close() of a _socketobj now releases the underlying
1513 socket again, which then gets closed as it becomes unreferenced.
1514
Fred Drake10497c82006-06-29 02:57:48 +00001515- Bug #1504333: Make sgmllib support angle brackets in quoted
1516 attribute values.
1517
1518- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1519 sgmllib ('[' and ']' were not accepted).
1520
Georg Brandl1be63af2006-06-28 20:23:25 +00001521- Fix a bug in the turtle module's end_fill function.
1522
Brett Cannon53ab5b72006-06-22 16:49:14 +00001523- Bug #1510580: The 'warnings' module improperly required that a Warning
1524 category be either a types.ClassType and a subclass of Warning. The proper
1525 check is just that it is a subclass with Warning as the documentation states.
1526
Georg Brandlad29e632006-06-21 17:45:17 +00001527- The compiler module now correctly compiles the new try-except-finally
1528 statement (bug #1509132).
1529
Neal Norwitz60373cd2006-06-22 06:30:50 +00001530- The wsgiref package is now installed properly on Unix.
1531
Vinay Sajip28e57612006-07-01 10:45:20 +00001532- A bug was fixed in logging.config.fileConfig() which caused a crash on
1533 shutdown when fileConfig() was called multiple times.
1534
Gerhard Häring762fbd32006-07-02 17:48:30 +00001535- The sqlite3 module did cut off data from the SQLite database at the first
1536 null character before sending it to a custom converter. This has been fixed
1537 now.
1538
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001539Extension Modules
1540-----------------
1541
Tim Peters112aad32006-07-19 00:03:19 +00001542- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1543 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1544 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001545
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001546- Assigning None to pointer type fields in ctypes structures possible
1547 overwrote the wrong fields, this is fixed now.
1548
1549- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1550 on non-Windows platforms.
1551
1552- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1553 integer or long, without range checking.
1554
1555- Patch #1517790: It is now possible to use custom objects in the ctypes
1556 foreign function argtypes sequence as long as they provide a from_param
1557 method, no longer is it required that the object is a ctypes type.
1558
1559- The '_ctypes' extension module now works when Python is configured
1560 with the --without-threads option.
1561
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001562- Bug #1513646: os.access on Windows now correctly determines write
1563 access, again.
1564
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001565- Bug #1512695: cPickle.loads could crash if it was interrupted with
1566 a KeyboardInterrupt.
1567
Neal Norwitza12aa882006-07-06 06:45:08 +00001568- Bug #1296433: parsing XML with a non-default encoding and
1569 a CharacterDataHandler could crash the interpreter in pyexpat.
1570
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001571- Patch #1516912: improve Modules support for OpenVMS.
1572

1574-----
1575
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001576- Automate Windows build process for the Win64 SSL module.
1577
Tim Peters32a83612006-07-10 21:08:24 +00001578- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001579 Previously, the slight difference could cause compilation errors of the
1580 'zlib' module on systems with more than one version of zlib.
1581
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001582- The MSI compileall step was fixed to also support a TARGETDIR
1583 with spaces in it.
1584
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001585- Bug #1517388: sqlite3.dll is now installed on Windows independent
1586 of Tcl/Tk.
1587
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001588- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001589 trying to be installed even though it's empty.

Neal Norwitzb15ac312006-06-29 04:10:08 +00001591Tests
1592-----
1593
1594- Call os.waitpid() at the end of tests that spawn child processes in order
1595 to minimize resources (zombies).
1596
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001597Documentation
1598-------------
1599
Nick Coghlan2d792252006-07-06 13:47:18 +00001600- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1601 documentation for the warnings module.
1602
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001603- Patch #1509163: MS Toolkit Compiler no longer available.
1604
Neal Norwitz56640df2006-07-10 02:36:41 +00001605- Patch #1504046: Add documentation for xml.etree.

Nick Coghlanc649ec52006-05-29 12:43:05 +00001608What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +00001609================================
Anthony Baxter51bcb682006-04-05 14:51:42 +00001610
Anthony Baxterd1136802006-06-19 12:04:15 +00001611*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +00001612
1613Core and builtins
1614-----------------
1615
Georg Brandla56b9152006-06-19 06:35:54 +00001616- Patch #1507676: Error messages returned by invalid abstract object operations
1617 (such as iterating over an integer) have been improved and now include the
1618 type of the offending object to help with debugging.
1619
Brett Cannonea3912b2006-06-13 21:46:41 +00001620- Bug #992017: A classic class that defined a __coerce__() method that returned
1621 its arguments swapped would infinitely recurse and segfault the interpreter.
1622
Neal Norwitz909eb122006-06-12 02:13:21 +00001623- Fix the socket tests so they can be run concurrently.
1624
Neal Norwitzb9845e72006-06-12 02:11:18 +00001625- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001626 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001627
Brett Cannon22565aa2006-06-09 22:31:23 +00001628- Bug #532646: object.__call__() will continue looking for the __call__
1629 attribute on objects until one without one is found. This leads to recursion
1630 when you take a class and set its __call__ attribute to an instance of the
1631 class. Originally fixed for classic classes, but this fix is for new-style.
1632 Removes the infinite_rec_3 crasher.
1633
Georg Brandl24250812006-06-09 18:45:48 +00001634- The string and unicode methods startswith() and endswith() now accept
1635 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1636
Brett Cannonde3b0522006-06-08 17:00:45 +00001637- Buffer objects, at the C level, never used the char buffer
1638 implementation even when the char buffer for the wrapped object was
1639 explicitly requested (originally returned the read or write buffer).
1640 Now a TypeError is raised if the char buffer is not present but is
1641 requested.
1642
Georg Brandlddbaa662006-06-04 21:56:52 +00001643- Patch #1346214: Statements like "if 0: suite" are now again optimized
1644 away like they were in Python 2.4.
1645
Georg Brandlb7c8f542006-05-27 12:30:25 +00001646- Builtin exceptions are now full-blown new-style classes instead of
1647 instances pretending to be classes, which speeds up exception handling
1648 by about 80% in comparison to 2.5a2.
1649
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001650- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1651 Unicode 4.1.
1652
Georg Brandlf4ef1162006-05-26 18:03:31 +00001653- Patch #921466: sys.path_importer_cache is now used to cache valid and
1654 invalid file paths for the built-in import machinery which leads to
1655 fewer open calls on startup.
1656
Tim Peters696cf432006-05-24 21:10:40 +00001657- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1658 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1659 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1660 the number of input digits (it was and remains linear-time for bases
1661 2, 4, 8, 16 and 32).
1662
Tim Petersb713ec22006-05-23 18:45:30 +00001663- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1664 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1665 an integer close to ``sys.maxint``. This was repaired by patch
1666 #1335972, which also gives a nice speedup.
1667
Richard Jonescebbefc2006-05-23 18:28:17 +00001668- Patch #1337051: reduced size of frame objects.
1669
1670- PyErr_NewException now accepts a tuple of base classes as its
1671 "base" parameter.
1672
Richard Jones7c88dcc2006-05-23 10:37:38 +00001673- Patch #876206: function call speedup by retaining allocated frame
1674 objects.
1675
Georg Brandl7b90e162006-05-18 07:01:27 +00001676- Bug #1462152: file() now checks more thoroughly for invalid mode
1677 strings and removes a possible "U" before passing the mode to the
1678 C library function.
1679
Neal Norwitz1004a532006-05-15 07:17:23 +00001680- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1681
Neal Norwitz373f0a72006-05-15 07:04:36 +00001682- Bug #1487966: Fix SystemError with conditional expression in assignment
1683
Martin v. Löwis879768d2006-05-11 13:28:43 +00001684- WindowsError now has two error code attributes: errno, which carries
1685 the error values from errno.h, and winerror, which carries the error
1686 values from winerror.h. Previous versions put the winerror.h values
1687 (from GetLastError()) into the errno attribute.
1688
Martin v. Löwis77736712006-05-04 05:51:03 +00001689- Patch #1475845: Raise IndentationError for unexpected indent.
1690
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001691- Patch #1479181: split open() and file() from being aliases for each other.
1692
Tim Peters44bd9862006-06-01 13:49:23 +00001693- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1694 methods were always silently ignored by dictionaries when comparing keys.
1695 They are now passed through (except when using the C API function
1696 ``PyDict_GetItem()``, whose semantics did not change).
1697
1698- Bug #1456209: In some obscure cases it was possible for a class with a
1699 custom ``__eq__()`` method to confuse dict internals when class instances
1700 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1701 No, you don't have any code that did this ;-)

1709
Brett Cannon6ee7d012006-06-08 16:23:04 +00001710- Change binascii.hexlify to accept a read-only buffer instead of only a char
1711 buffer and actually follow its documentation.
1712
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001713- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1714
Nick Coghlanc649ec52006-05-29 12:43:05 +00001715- Patch #1478788 (modified version): The functional extension module has
1716 been renamed to _functools and a functools Python wrapper module added.
1717 This provides a home for additional function related utilities that are
1718 not specifically about functional programming. See PEP 309.
1719
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001720- Patch #1493701: performance enhancements for struct module.

Georg Brandl8d3342b2006-05-16 07:38:27 +00001724- Patch #1435422: zlib's compress and decompress objects now have a
1725 copy() method.
1726
Andrew MacIntyre92913322006-06-13 15:04:24 +00001727- Patch #1454481: thread stack size is now tunable at runtime for thread
1728 enabled builds on Windows and systems with Posix threads support.
1729
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001730- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1731 (up to the system limit of 32K characters).
1732
1733- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1734 As a result, these functions now raise WindowsError instead of OSError.
1735
Tim Peters7a822da2006-05-25 21:50:17 +00001736- ``time.clock()`` on Win64 should use the high-performance Windows
1737 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1738 Windows platforms).
1739
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001740- Calling Tk_Init twice is refused if the first call failed as that
1741 may deadlock.
1742
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001743- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1744 accept it without potentially using an uninitialized pointer.
1745
1746- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1747 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1748 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001749
Gregory P. Smith372b5832006-06-05 18:48:21 +00001750- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001751 [pybsddb project SF patch number 1466734]
1752
Gregory P. Smith372b5832006-06-05 18:48:21 +00001753- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1754 parameter is supplied. [SF pybsddb bug #1477863]
1755
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001756- bsddb: the __len__ method of a DB object has been fixed to return correct
1757 results. It could previously incorrectly return 0 in some cases.
1758 Fixes SF bug 1493322 (pybsddb bug 1184012).
1759
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001760- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1761 aborts the db transaction safely when a modifier callback fails.
1762 Fixes SF python patch/bug #1408584.
1763
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001764- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001765 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001766 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1767 database calls that would previously deadlock. [SF python bug #775414]

1791 mime.types file for determining MIME types.
1792
Georg Brandl2605ca82006-06-14 06:08:31 +00001793- Bug #1339007: Shelf objects now don't raise an exception in their
1794 __del__ method when initialization failed.
1795
Martin v. Löwisd8251432006-06-14 05:21:04 +00001796- Patch #1455898: The MBCS codec now supports the incremental mode for
1797 double-byte encodings.
1798
Tim Peters43898b42006-06-14 04:09:25 +00001799- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1800 guarantee that adjacent triples in the return list always describe
1801 non-adjacent blocks. Previously, a pair of matching blocks could end
1802 up being described by multiple adjacent triples that formed a partition
1803 of the matching pair.
1804
Greg Ward0e0c9f42006-06-11 16:24:11 +00001805- Bug #1498146: fix optparse to handle Unicode strings in option help,
1806 description, and epilog.
1807
Greg Wardd1c797e2006-06-11 14:42:41 +00001808- Bug #1366250: minor optparse documentation error.
1809
Greg Ward7f547402006-06-11 00:40:49 +00001810- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1811 clarify docs.
1812
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001813- The wsgiref package has been added to the standard library.
1814
Nick Coghlan676725d2006-06-08 13:54:49 +00001815- The functions update_wrapper() and wraps() have been added to the functools
1816 module. These make it easier to copy relevant metadata from the original
1817 function when writing wrapper functions.
1818
Tim Petersd6a9eef2006-06-05 01:48:21 +00001819- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1820 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001821
Martin v. Löwis3f767792006-06-04 19:36:28 +00001822- Patch #1359618: Speed up charmap encoder by using a trie structure
1823 for lookup.
1824
Tim Petersd609b1a2006-06-02 23:22:51 +00001825- The functions in the ``pprint`` module now sort dictionaries by key
1826 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1827 if and only if its display required more than one line, although that
1828 wasn't documented. The new behavior increases predictability; e.g.,
1829 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1830
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001831- Patch #1497027: try HTTP digest auth before basic auth in urllib2

1840
Georg Brandlb89316f2006-05-17 15:51:16 +00001841- Patch #1180296: Two new functions were added to the locale module:
1842 format_string() to get the effect of "format % items" but locale-aware,
1843 and currency() to format a monetary number with currency sign.
1844
Georg Brandle3a25832006-05-17 14:56:04 +00001845- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1846 and several features added, such as speed and geometry control.
1847
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001848- Patch #1488881: add support for external file objects in bz2 compressed
1849 tarfiles.
1850
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001851- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1852 stdout arguments, making it possible to redirect input and output
1853 for remote debugging.
1854
1855- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1856 a couple of issues, notably handling of long file names using the
1857 GNU LONGNAME extension.
1858
1859- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1860 new flag when ``name`` is already the name of an option flag.
1861
1862- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1863 package.
1864
1865- Patch #1472854: make the rlcompleter.Completer class usable on non-
1866 UNIX platforms.
1867
1868- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1869
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001870- Bug #1472827: correctly escape newlines and tabs in attribute values in
1871 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001901What's New in Python 2.5 alpha 2?
1902=================================
1903
1904*Release date: 27-APR-2006*
1905
1906Core and builtins
1907-----------------
1908
Thomas Heller1b046642006-04-18 18:51:06 +00001909- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1910 by converting these apis from macros into exported functions again:
1911
1912 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1913 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1914 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1915 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1916 PyRun_String Py_CompileString
1917
Martin v. Löwis45294a92006-04-18 06:24:08 +00001918- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1919
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001920- All uses of PyStructSequence_InitType have been changed to initialize
1921 the type objects only once, even if the interpreter is initialized
1922 multiple times.
1923
Neal Norwitz61546162006-04-14 05:20:28 +00001924- Bug #1454485, array.array('u') could crash the interpreter. This was
1925 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1926 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1927
1928- Py_UNICODE is unsigned. It was always documented as unsigned, but
1929 due to a bug had a signed value in previous versions.
1930
Tim Peters3a5e8b12006-04-11 01:44:07 +00001931- Patch #837242: ``id()`` of any Python object always gives a positive
1932 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1933 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001934 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001935 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001936
Tim Peters3a5e8b12006-04-11 01:44:07 +00001937 def __hash__(self):
1938 return id(self) # WRONG
1939
1940 because a hash result must be a (short) Python int but it was always
1941 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001942 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001943 was always usable as a hash value before this patch. That's no longer
1944 necessarily so.
1945
1946- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001947 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001948 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001949 #1454844)
1950
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001951- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1952 involving generators that have paused outside of any ``try`` or ``with``
1953 blocks. (In 2.5a1, a paused generator that was part of a reference
1954 cycle could not be garbage collected, regardless of whether it was
1955 paused in a ``try`` or ``with`` block.)

1969 the cachesize parameter.
1970
1971- Bug #1149413: bsddb.*open() no longer raises an exception when using
1972 a temporary db (file=None) with the 'n' flag to truncate on open.
1973
1974- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1975 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001976
Armin Rigoa9017c32006-04-19 11:50:27 +00001977- Patch #1062014: AF_UNIX sockets under Linux have a special

Tim Peters711bf302006-04-25 03:31:36 +00001987- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1988 a doctest to be skipped (the code is not run, and the expected output
1989 or exception is ignored).
1990
Nick Coghlanda2268f2006-04-24 04:37:15 +00001991- Fixed contextlib.nested to cope with exceptions being raised and
1992 caught inside exit handlers.
1993
Greg Wardab05edc2006-04-23 03:47:58 +00001994- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1995 hex, octal, or binary; add ``append_const`` action; keep going if
1996 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1997 added ``epilog`` for better help generation).
1998
Tim Peters21fbd572006-04-21 21:18:10 +00001999- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2000 called from a thread spawned as a side effect of importing a module.
2001
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002002- The pydoc module now supports documenting packages contained in
2003 .zip or .egg files.
2004
2005- The pkgutil module now has several new utility functions, such
2006 as ``walk_packages()`` to support working with packages that are either
2007 in the filesystem or zip files.
2008
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002009- The mailbox module can now modify and delete messages from
2010 mailboxes, in addition to simply reading them. Thanks to Gregory
2011 K. Johnson for writing the code, and to the 2005 Google Summer of
2012 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002013
Tim Petersc7605f22006-04-17 21:12:33 +00002014- The ``__del__`` method of class ``local`` in module ``_threading_local``
2015 returned before accomplishing any of its intended cleanup.
2016
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002017- Patch #790710: Add breakpoint command lists in pdb.

2062
Anthony Baxter51bcb682006-04-05 14:51:42 +00002063Tests
2064-----
2065
Nick Coghlanda2268f2006-04-24 04:37:15 +00002066- test_contextlib now checks contextlib.nested can cope with exceptions
2067 being raised and caught inside exit handlers.

2070
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002071- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2072 it separately and by hand. It also wasn't cleaning up its changes to
2073 the current Decimal context.
2074
Thomas Woutersabd08882006-04-26 15:53:30 +00002075- regrtest.py now has a -M option to run tests that test the new limits of
2076 containers, on 64-bit architectures. Running these tests is only sensible
2077 on 64-bit machines with more than two gigabytes of memory. The argument
2078 passed is the maximum amount of memory for the tests to use.

2087-------------
2088
Tim Petersb06d28c2006-05-12 01:57:59 +00002089- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2090
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002091- PEP 343: Added Context Types section to the library reference
2092 and attempted to bring other PEP 343 related documentation into
2093 line with the implementation and/or python-dev discussions.
2094
Tim Peters8dc73d22006-04-24 02:03:16 +00002095- Bug #1337990: clarified that ``doctest`` does not support examples
2096 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002104Core and builtins
2105-----------------
2106
Nick Coghlan43832302006-04-23 17:04:07 +00002107- PEP 338: -m command line switch now delegates to runpy.run_module
2108 allowing it to support modules in packages and zipfiles
2109
Martin v. Löwisc661b882006-04-20 04:54:23 +00002110- On Windows, .DLL is not an accepted file name extension for
2111 extension modules anymore; extensions are only found if they
2112 end in .PYD.
2113
Martin v. Löwisea62d252006-04-03 10:56:49 +00002114- Bug #1421664: sys.stderr.encoding is now set to the same value as
2115 sys.stdout.encoding.
2116
Neal Norwitz92e212f2006-04-03 04:48:37 +00002117- __import__ accepts keyword arguments.
2118
Georg Brandlccadf842006-03-31 18:54:53 +00002119- Patch #1460496: round() now accepts keyword arguments.
2120
Anthony Baxter262c00a2006-03-30 10:53:17 +00002121- Fixed bug #1459029 - unicode reprs were double-escaped.
2122
Hye-Shik Changd478f342006-03-23 12:32:36 +00002123- Patch #1396919: The system scope threads are reenabled on FreeBSD
2124 5.4 and later versions.
2125
Neal Norwitze98ccf62006-03-23 05:39:47 +00002126- Bug #1115379: Compiling a Unicode string with an encoding declaration
2127 now gives a SyntaxError.
2128
Georg Brandlabd1ff82006-03-18 07:59:59 +00002129- Previously, Python code had no easy way to access the contents of a
2130 cell object. Now, a ``cell_contents`` attribute has been added
2131 (closes patch #1170323).
2132
Tim Peterscf79aac2006-03-16 01:14:46 +00002133- Patch #1123430: Python's small-object allocator now returns an arena to
2134 the system ``free()`` when all memory within an arena becomes unused
2135 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2136 freed. Some applications will see a drop in virtual memory size now,
2137 especially long-running applications that, from time to time, temporarily
2138 use a large number of small objects. Note that when Python returns an
2139 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002140 platform C library will in turn return that memory to the operating system.
2141 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002142 appears to be effective at least on Microsoft C and gcc-based systems.
2143 Thanks to Evan Jones for hard work and patience.
2144
Georg Brandl533ff6f2006-03-08 18:09:27 +00002145- Patch #1434038: property() now uses the getter's docstring if there is
2146 no "doc" argument given. This makes it possible to legitimately use
2147 property() as a decorator to produce a read-only property.
2148
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002149- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2150 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2151 of requiring an int or long in slicing and a few other contexts, enabling
2152 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2153
Neal Norwitz995acdf2006-03-07 05:01:00 +00002154- Fixed various bugs reported by Coverity's Prevent tool.
2155
Brett Cannonbf364092006-03-01 04:25:17 +00002156- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2157 new exception base class, BaseException, which has a new message attribute.
2158 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2159 Raising a string exception now raises a DeprecationWarning.
2160
Thomas Woutersfb609f42006-02-28 16:37:25 +00002161- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2162 explicitly relative, using 'from .module import name' to mean 'from the same
2163 package as this module is in. Imports without dots still default to the
2164 old relative-then-absolute, unless 'from __future__ import
2165 absolute_import' is used.
2166
Brett Cannona7446e32006-02-27 23:39:10 +00002167- Properly check if 'warnings' raises an exception (usually when a filter set
2168 to "error" is triggered) when raising a warning for raising string
2169 exceptions.
2170
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002171- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002172 The name was removed from Include/code.h.
2173
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002174- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002175
Guido van Rossum1968ad32006-02-25 22:38:04 +00002176- Patch 1433928:
2177 - The copy module now "copies" function objects (as atomic objects).
2178 - dict.__getitem__ now looks for a __missing__ hook before raising
2179 KeyError.
2180
Tim Peters84ef21c2006-02-28 20:39:06 +00002181- PEP 343: with statement implemented. Needs ``from __future__ import
2182 with_statement``. Use of 'with' as a variable will generate a warning.
2183 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002184 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002185 The following objects have __context__ methods:
2186 - The built-in file type.
2187 - The thread.LockType type.
2188 - The following types defined by the threading module:
2189 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2190 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002191
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002192- Fix the encodings package codec search function to only search
2193 inside its own package. Fixes problem reported in patch #1433198.
2194
2195 Note: Codec packages should implement and register their own
2196 codec search function. PEP 100 has the details.
2197
Tim Peters9ea89d22006-06-04 03:26:02 +00002198- PEP 353: Using ``Py_ssize_t`` as the index type.
2199
2200- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2201 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2202 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2203 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2204 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002205
Neal Norwitzfc76d632006-01-10 06:03:13 +00002206- Patch #1400181, fix unicode string formatting to not use the locale.
2207 This is how string objects work. u'%f' could use , instead of .
2208 for the decimal point. Now both strings and unicode always use periods.
2209
Neal Norwitz671b9e32006-01-09 07:07:12 +00002210- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2211 configure would break checking curses.h.
2212
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002213- Bug #959576: The pwd module is now builtin. This allows Python to be
2214 built on UNIX platforms without $HOME set.
2215
Neal Norwitzc10978f2005-12-19 06:07:16 +00002216- Bug #1072182, fix some potential problems if characters are signed.
2217
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002218- Bug #889500, fix line number on SyntaxWarning for global declarations.
2219
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002220- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2221
Neal Norwitze7214a12005-12-18 05:03:17 +00002222- Support for converting hex strings to floats no longer works.
2223 This was not portable. float('0x3') now raises a ValueError.
2224
Barry Warsaw2a38a862005-12-18 01:27:35 +00002225- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002226 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002227 is now displayed in interactive prompt banner.
2228
Georg Brandlfa166682005-12-17 21:45:17 +00002229- Implementation of PEP 341 - Unification of try/except and try/finally.
2230 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002231 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002232
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002233- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2234 now encodes backslash correctly.
2235
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002236- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2237
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002238- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002239 and long longs.
2240
Neal Norwitz67715f02005-11-09 06:59:35 +00002241- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002242 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002243 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002244
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002245- Replaced most Unicode charmap codecs with new ones using the
2246 new Unicode translate string feature in the builtin charmap
2247 codec; the codecs were created from the mapping tables available
2248 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2249 encodings now include a mapping for the Apple logo)
2250
Tim Peterse3547fd2005-12-16 23:13:57 +00002251- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002252
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002253- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002254
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002255- A new AST parser implementation was completed. The abstract
2256 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002257 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002258
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002259- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002260 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2261
Neal Norwitz708e51a2005-10-03 04:48:15 +00002262- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2263
Neal Norwitz11bd1192005-10-03 00:54:56 +00002264- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2265 Provide a warning when a directory is passed on the command line.
2266
Neal Norwitz40d37812005-10-02 01:48:49 +00002267- Fix segfault with invalid coding.
2268
2269- SF bug #772896: unknown encoding results in MemoryError.
2270
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002271- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002272 supported a __len__() method which evaluated to False when the iterator
2273 was empty.
2274
Guido van Rossum630db602005-09-20 18:49:54 +00002275- On 64-bit platforms, when __len__() returns a value that cannot be
2276 represented as a C int, raise OverflowError.
2277
Skip Montanarof8948ca2005-09-19 03:54:46 +00002278- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002279 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002280
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002281- SF bug #893549: parsing keyword arguments was broken with a few format
2282 codes.
2283
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002284- Changes donated by Elemental Security to make it work on AIX 5.3
2285 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2286 bug #105470: test_pwd fails on 64bit system (Opteron).
2287
Guido van Rossum539c6622005-09-14 17:49:54 +00002288- Changes donated by Elemental Security to make it work on HP-UX 11 on
2289 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2290
Georg Brandl4550b8d2005-08-26 06:43:52 +00002291- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002292 (fixes bug #1119418).
2293
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002294- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2295
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002296- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2297 exceptions that cause a function to exit.
2298
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002299- The implementation of set() and frozenset() was revised to use its
2300 own internal data structure. Memory consumption is reduced by 1/3
2301 and there are modest speed-ups as well. The API is unchanged.
2302
Tim Petersde7990b2005-07-17 23:45:23 +00002303- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2304
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002305- SF bug #1229429: PyObject_CallMethod failed to decrement some
2306 reference counts in some error exit cases.
2307
Tim Petersecc6e6a2005-07-10 22:30:55 +00002308- SF bug #1185883: Python's small-object memory allocator took over
2309 a block managed by the platform C library whenever a realloc specified
2310 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002311 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002312 portable way to copy data from the C-managed block into Python's
2313 small-object space without risking a memory fault. Python's small-object
2314 realloc now leaves such blocks under the control of the platform C
2315 realloc.
2316
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002317- SF bug #1232517: An overflow error was not detected properly when
2318 attempting to convert a large float to an int in os.utime().
2319
Raymond Hettinger3296e692005-06-29 23:29:56 +00002320- SF bug #1224347: hex longs now print with lowercase letters just
2321 like their int counterparts.
2322
Michael W. Hudson188d4362005-06-20 16:52:57 +00002323- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2324 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2325 interpreter states; back out that fix and do a better job (see
2326 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2327 for a longer write-up of the problem).
2328
Michael W. Hudsondf888462005-06-03 14:41:55 +00002329- SF patch #1180995: marshal now uses a binary format by default when
2330 serializing floats.
2331
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002332- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2333 the routines that promise to produce IEEE 754 binary representations
2334 of floats now simply copy bytes around.
2335
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002336- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2337 278.
2338
Brett Cannonc3647ac2005-04-26 03:45:26 +00002339- patch #1109424: int, long, float, complex, and unicode now check for the
2340 proper magic slot for type conversions when subclassed. Previously the
2341 magic slot was ignored during conversion. Semantics now match the way
2342 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002343 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002344 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002345 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002346
Barry Warsawc8d907c2005-04-19 23:43:40 +00002347- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2348 NULL, now raise an AttributeError when attempting to set or delete the
2349 attribute. Previously a TypeError was raised, but this was inconsistent
2350 with the equivalent pure-Python implementation.
2351
Michael W. Hudson774479c2005-04-18 08:46:17 +00002352- It is now safe to call PyGILState_Release() before
2353 PyEval_InitThreads() (note that if there is reason to believe there
2354 are multiple threads around you still must call PyEval_InitThreads()
2355 before using the Python API; this fix is for extension modules that
2356 have no way of knowing if Python is multi-threaded yet).
2357
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002358- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2359 disabled caused a crash.
2360
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002361- Bug #1165306: instancemethod_new allowed the creation of a method
2362 with im_class == im_self == NULL, which caused a crash when called.
2363
Tim Petersecc6e6a2005-07-10 22:30:55 +00002364- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002365 fixes the crash seen in bug #1165761
2366
Raymond Hettinger96229b12005-03-11 06:49:40 +00002367- Added two new builtins, any() and all().
2368
Brett Cannon409d8f22005-03-05 06:47:57 +00002369- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002370 (e.g., ``class C(): pass`` is no longer a syntax error).
2371 Patch #1176012 added support to the 'parser' module and 'compiler' package
2372 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002373

2377 returning None.
2378
Tim Petersecc6e6a2005-07-10 22:30:55 +00002379- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002380 ('\') with a specific error message.
2381
Martin v. Löwisff232d72005-03-03 09:24:38 +00002382- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2383
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002384- Bug #1124295: the __name__ attribute of file objects was

2386
Tim Petersecc6e6a2005-07-10 22:30:55 +00002387- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002388 an ferror() call.
2389
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002390- min() and max() now support key= arguments with the same meaning as in
2391 list.sort().
2392
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002393- The peephole optimizer now performs simple constant folding in expressions:
2394 (2+3) --> (5).
2395
Raymond Hettingera422c342005-01-11 03:03:27 +00002396- set and frozenset objects can now be marshalled. SF #1098985.
2397
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002398- Bug #1077106: Poor argument checking could cause memory corruption
2399 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002400
Jeremy Hyltonab630502005-02-04 18:44:06 +00002401- The parser did not complain about future statements in illegal
2402 positions. It once again reports a syntax error if a future
2403 statement occurs after anything other than a doc string.
2404
Neil Schemenauercf52c072005-08-12 17:34:58 +00002405- Change the %s format specifier for str objects so that it returns a
2406 unicode instance if the argument is not an instance of basestring and
2407 calling __str__ on the argument returns a unicode instance.
2408
Tim Petersf4e69282006-02-27 17:15:31 +00002409- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2410 current thread state when the auto-GIL-state machinery knows about
2411 it (since the thread state is being deleted, continuing to remember it
2412 can't help, but can hurt if another thread happens to get created with
2413 the same thread id).

Nick Coghlan43832302006-04-23 17:04:07 +00002609- PEP 338: new module runpy defines a run_module function to support
2610 executing modules which provide access to source code or a code object
2611 via the PEP 302 import mechanisms.
2612
Anthony Baxter93f5b932006-04-03 08:05:07 +00002613- The email module's parsedate_tz function now sets the daylight savings
2614 flag to -1 (unknown) since it can't tell from the date whether it should

2621 in attribute values.
2622
Anthony Baxterc51ee692006-04-01 00:57:31 +00002623- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002624 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002625 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002626 module will not be built.
2627
Tim Petersc17976e2006-04-01 00:26:53 +00002628- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2629 aren't officially supported here, and trying to use them will probably
2630 raise an exception some day. But dicts have been allowed, and "mostly
2631 worked", so support for them won't go away without warning.
2632
Georg Brandl338ef7d2006-03-31 18:42:16 +00002633- Bug #1445068: getpass.getpass() can now be given an explicit stream
2634 argument to specify where to write the prompt.
2635

2645 to make it easier to monitor when daemon threads have completed
2646 processing all enqueued tasks. Patch #1455676.
2647
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002648- popen2.Popen objects now preserve the command in a .cmd attribute.
2649

2651
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002652- email 4.0 package now integrated. This is largely the same as the email 3.0
2653 package that was included in Python 2.3, except that PEP 8 module names are
2654 now used (e.g. mail.message instead of email.Message). The MIME classes
2655 have been moved to a subpackage (e.g. email.mime.text instead of
2656 email.MIMEText). The old names are still supported for now. Several
2657 deprecated Message methods have been removed and lots of bugs have been
2658 fixed. More details can be found in the email package documentation.
2659
Walter Dörwald40108c92006-03-27 08:15:44 +00002660- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2661 (a subclass of tuple) that provides incremental decoders and encoders
2662 (a way to use stateful codecs without the stream API). Python functions
2663 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2664 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2665 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002666
Walter Dörwald067db482006-03-15 22:17:27 +00002667- Patch #1359365: Calling next() on a closed StringIO.String object raises
2668 a ValueError instead of a StopIteration now (like file and cString.String do).
2669 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2670 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002671
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002672- A regrtest option -w was added to re-run failed tests in verbose mode.

2745 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2746 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2747 Ronald L. Rivest offered this advice for Python:
2748
2749 "The consensus of researchers in this area (at least as
2750 expressed at the NIST Hash Function Workshop 10/31/05),
2751 is that SHA-256 is a good choice for the time being, but
2752 that research should continue, and other alternatives may
2753 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002754
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002755- Added a subset of Fredrik Lundh's ElementTree package. Available

Raymond Hettinger267b8682005-03-27 10:47:39 +00002871- decimal operator and comparison methods now return NotImplemented
2872 instead of raising a TypeError when interacting with other types. This
2873 allows other classes to implement __radd__ style methods and have them
2874 work as expected.
2875
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002876- Bug #1163325: Decimal infinities failed to hash. Attempting to
2877 hash a NaN raised an InvalidOperation instead of a TypeError.
2878
Tim Petersecc6e6a2005-07-10 22:30:55 +00002879- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00002880 stream compression; add, for symmetry reasons, r:* as a synonym of r.
2881
Martin v. Löwis00a73e72005-03-04 19:40:34 +00002882- Patch #1043890: Add extractall method to tarfile.
2883
Martin v. Löwisc72dd382005-03-04 13:50:17 +00002884- Patch #1075887: Don't require MSVC in distutils if there is nothing
2885 to build.
2886
Martin v. Löwis637431b2005-03-03 23:12:42 +00002887- Patch #1103407: Properly deal with tarfile iterators when untarring
2888 symbolic links on Windows.
2889
Tim Petersecc6e6a2005-07-10 22:30:55 +00002890- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +00002891 profile.py if available.
2892
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00002893- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
2894
Martin v. Löwisc5574e82005-03-03 10:57:37 +00002895- Patch #1117454: Remove code to special-case cookies without values
2896 in LWPCookieJar.
2897
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00002898- Patch #1117339: Add cookielib special name tests.
2899
Martin v. Löwise869eb12005-03-03 09:46:07 +00002900- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
2901
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00002902- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
2903
Martin v. Löwisdf241532005-03-03 08:17:42 +00002904- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
2905
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00002906- Patch #1104111: Alter setup.py --help and --help-commands.
2907
Martin v. Löwis4afe1542005-03-01 08:09:28 +00002908- Patch #1121234: Properly cleanup _exit and tkerror commands.
2909
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00002910- Patch #1049151: xdrlib now unpacks booleans as True or False.
2911
Raymond Hettingerbab41432005-02-05 01:31:19 +00002912- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2913
Guido van Rossumd0641422005-02-03 15:01:24 +00002914- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2915 disables recursive traversal through instance attributes, which can
2916 be exploited in various ways.
2917
Tim Peterse3547fd2005-12-16 23:13:57 +00002918- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002919 flags on the HTTP listening socket.
2920
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002921- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2922 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2923
Fred Drakefbdeaad2006-07-29 16:56:15 +00002924- Patches #893642, #1039083: add allow_none, encoding arguments to
2925 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002926
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002927- Bug #1110478: Revert os.environ.update to do putenv again.
2928
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002929- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2930
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002931- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2932
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002933- Enhancements to the csv module:
2934
2935 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002936 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002937 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002938 + Dialect parameter parsing has been re-implemented to improve error
2939 reporting.
2940 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2941 dictates.
2942 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002943 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002944 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002945 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2946 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002947 + reader now allows \r characters to be quoted (previously it only allowed
2948 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002949 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002950 + Dialect classes passed to the module are no longer instantiated by
2951 the module before being parsed (the former validation scheme required
2952 this, but the mechanism was unreliable).
2953 + The dialect registry now contains instances of the internal
2954 C-coded dialect type, rather than references to python objects.
2955 + the internal c-coded dialect type is now immutable.
2956 + register_dialect now accepts the same keyword dialect specifications
2957 as the reader and writer, allowing the user to register dialects
2958 without first creating a dialect class.
2959 + a configurable limit to the size of parsed fields has been added -
2960 previously, an unmatched quote character could result in the entire
2961 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002962 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002963 the parser field size limit (returning the former limit). The initial
2964 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002965 + A line_num attribute has been added to the reader object, which tracks
2966 the number of lines read from the source iterator. This is not
2967 the same as the number of records returned, as records can span
2968 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002969 + reader and writer objects were not being registered with the cyclic-GC.
2970 This has been fixed.
2971
Brett Cannone6539c42005-01-08 02:43:53 +00002972- _DummyThread objects in the threading module now delete self.__block that is
2973 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2974 lock primitives tend to be limited in number and thus should not be wasted on
2975 a _DummyThread object. Fixes bug #1089632.
2976
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002977- The imghdr module now detects Exif files.
2978
Raymond Hettinger6065d322004-12-20 23:51:53 +00002979- StringIO.truncate() now correctly adjusts the size attribute.
2980 (Bug #951915).
2981
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002982- locale.py now uses an updated locale alias table (built using
2983 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2984 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002985 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002986
Raymond Hettinger3557f422004-12-07 12:02:02 +00002987- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2988
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002989- the pickle module no longer accepts the deprecated None option in the
2990 args tuple returned by __reduce__().
2991
Brett Cannon84667c02004-12-07 03:25:18 +00002992- optparse now optionally imports gettext. This allows its use in setup.py.
2993
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002994- the pickle module no longer uses the deprecated bin parameter.
2995
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002996- the shelve module no longer uses the deprecated binary parameter.
2997
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002998- the pstats module no longer uses the deprecated ignore() method.
2999
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003000- the filecmp module no longer uses the deprecated use_statcache argument.
3001
Raymond Hettinger664347b2004-12-04 21:21:53 +00003002- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3003 extended or overridden by subclasses. Formerly, the subclassed method would
3004 be ignored by the rest of the module. (Bug #1078905).
3005
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003006- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003007 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003008
Walter Dörwald36733692004-12-22 12:50:50 +00003009- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3010 once when a size argument is given. This prevents a buffer overflow in the
3011 tokenizer with very long source lines.
3012
Barry Warsaw538561e2006-01-01 21:48:54 +00003013- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3014 immediately after creating the object, without any intervening
3015 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003016
Skip Montanaro05885812005-01-16 20:48:27 +00003017- The reconvert.quote function can now emit triple-quoted strings. The
3018 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003019
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003020- ``UserString.MutableString`` now supports negative indices in
3021 ``__setitem__`` and ``__delitem__``
3022
Greg Ward40407942005-03-05 02:53:17 +00003023- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3024 correctly.
3025
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003026- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3027 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3028 character even if the user has passed a size parameter to get a proper
3029 line ending. Remove the special handling of a "\r\n" that has been split
3030 between two lines.
3031
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003032- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3033 about illegal code points. The codec now supports PEP 293 style error
3034 handlers.
3035
Walter Dörwald78a78b02005-09-01 12:04:29 +00003036- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003037 from the input stream, so that the output is a byte string in the correct
3038 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003039
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003040- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3041 considering it exactly like a '*'.
3042
Walter Dörwald007f8df2005-10-09 19:42:27 +00003043- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3044 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003045
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003046- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3047
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003048- Patch #1413711: Certain patterns of differences were making difflib
3049 touch the recursion limit.
3050
Walter Dörwald58917a62006-03-31 15:26:22 +00003051- Bug #947906: An object oriented interface has been added to the calendar
3052 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003053 called as a script (e.g. via ``python -mcalendar``). Localized month and
3054 weekday names can be ouput (even if an exotic encoding is used) using
3055 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003056

3058-----
3059
Neal Norwitz602d3392006-03-31 08:21:40 +00003060- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3061 by using -mieee gcc option.
3062
Martin v. Löwis86d66262006-02-17 08:40:11 +00003063- Patch #1432345: Make python compile on DragonFly.
3064
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003065- Build support for Win64-AMD64 was added.
3066
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003067- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3068
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003069- Patch #881820: look for openpty and forkpty also in libbsd.
3070
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003071- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3072 The zlib module is now builtin on Windows.
3073
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003074- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3075
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003076- Bug #1189330: configure did not correctly determine the necessary
3077 value of LINKCC if python was built with GCC 4.0.
3078
Trent Mick8321b422005-07-26 02:29:21 +00003079- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3080 vulnerability in zlib 1.2.1 and 1.2.2.
3081
Brett Cannon08cd5982005-04-24 22:26:38 +00003082- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3083 flags that change binary compatibility. Changes were also made to
3084 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003085 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003086
Bob Ippolitoed233462005-03-29 13:47:59 +00003087- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3088 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3089 no longer exists). This configure patch makes things right.
3090
Martin v. Löwise2713be2005-03-08 15:03:08 +00003091- Bug #1158607: Build with --disable-unicode again.
3092
Brett Cannon46d96232005-02-16 00:07:19 +00003093- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3094 defined. Discovered as a result of not being able to build on OS X.
3095
Brett Cannon516592f2004-12-07 00:42:59 +00003096- setup.py now uses the directories specified in LDFLAGS using the -L option
3097 and in CPPFLAGS using the -I option for adding library and include
3098 directories, respectively, for compiling extension modules against. This has
3099 led to the core being compiled using the values in CPPFLAGS. It also removes
3100 the need for the special-casing of both DarwinPorts and Fink for darwin since
3101 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3102 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3103 Fink, ``-I/opt/local/include`` for DarwinPorts).
3104
Brett Cannon43802422005-02-10 20:48:03 +00003105- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3106 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3107 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3108 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003110C API
3111-----
3112
Tim Petersc9d78aa2006-03-26 23:27:58 +00003113- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3114 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3115 is obtained via the ``PyObject_`` family, it must be released via the
3116 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3117 always been officially true, but when Python's small-object allocator was
3118 introduced, an attempt was made to cater to a few extension modules
3119 discovered at the time that obtained memory via ``PyObject_New`` but
3120 released it via ``PyMem_DEL``. It's years later, and if such code still
3121 exists it will fail now (probably with segfaults, but calling wrong
3122 low-level memory management functions can yield many symptoms).
3123
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003124- Added a C API for set and frozenset objects.
3125
Raymond Hettinger66517482004-12-03 11:45:13 +00003126- Removed PyRange_New().
3127
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003128- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3129 mapping argument now. This string is used as a mapping table. Byte values
3130 greater than the length of the string and 0xFFFE are treated as undefined
3131 mappings.
