901-----------------
902
Neal Norwitz0bcafac2006-09-11 08:51:17 +0000903- Make _PyGILState_NoteThreadState() static, it was not used anywhere
904 outside of pystate.c and should not be necessary.
905
Brett Cannon19d76c52006-09-09 07:18:44 +0000906- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
907 allows calling unicode() on exceptions classes directly to succeed.
908
Georg Brandlecab6232006-09-06 06:47:02 +0000909- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
910 Also make sure that every exception class has __module__ set to
911 'exceptions'.
912
Georg Brandl37a9e572006-09-06 06:09:34 +0000913- Bug #1550983: emit better error messages for erroneous relative

915
Tim Peterscbdd3502006-09-05 01:47:53 +0000916- Overflow checking code in integer division ran afoul of new gcc
917 optimizations. Changed to be more standard-conforming.

923
Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000924- The return tuple from str.rpartition(sep) is (tail, sep, head) where
925 head is the original string if sep was not found.
926
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000927- Bug #1520864: unpacking singleton tuples in list comprehensions and
928 generator expressions (x for x, in ... ) works again. Fixing this problem
929 required changing the .pyc magic number. This means that .pyc files
930 generated before 2.5c2 will be regenerated.

1042Core and builtins
1043-----------------
1044
Neal Norwitz24b6f202006-09-05 04:43:56 +00001045- Fix infinite recursion when subclassing long and overriding __hash__.
1046
1047- Fix concatenation (+=) of long strings.
1048
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001049- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001050 compared equal or unequal to a string and a UnicodeDecodeError
1051 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001052
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001053 Instead, the equal (==) and unequal (!=) comparison operators will
1054 now issue a UnicodeWarning and interpret the two objects as
1055 unequal. The UnicodeWarning can be filtered as desired using
1056 the warning framework, e.g. silenced completely, turned into an
1057 exception, logged, etc.
1058
1059 Note that compare operators other than equal and unequal will still
1060 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001061
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001062- Fix segfault when doing string formatting on subclasses of long.
1063
1064- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1065 with new-style classes.
1066
1067- Fix bug related to __len__ functions returning negative values with
1068 classic classes.
1069
1070- Patch #1538606, Fix __index__() clipping. There were some problems
1071 discovered with the API and how integers that didn't fit into Py_ssize_t
1072 were handled. This patch attempts to provide enough alternatives
1073 to effectively use __index__.
1074
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001075- Bug #1536021: __hash__ may now return long int; the final hash
1076 value is obtained by invoking hash on the long int.
1077
Thomas Hellerab1049c2006-08-08 17:37:00 +00001078- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1079
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001080- Bug #1535165: fixed a segfault in input() and raw_input() when
1081 sys.stdin is closed.
1082
Thomas Heller74d36f02006-08-04 18:17:40 +00001083- On Windows, the PyErr_Warn function is now exported from
1084 the Python dll again.
1085
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001086- Bug #1191458: tracing over for loops now produces a line event
1087 on each iteration. Fixing this problem required changing the .pyc
1088 magic number. This means that .pyc files generated before 2.5c1
1089 will be regenerated.
1090
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001091- Bug #1333982: string/number constants were inappropriately stored
1092 in the byte code and co_consts even if they were not used, ie
1093 immediately popped off the stack.
1094
Georg Brandle9462c72006-08-04 18:03:37 +00001095- Fixed a reference-counting problem in property().

1099-------
1100
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001101- Fix a bug in the ``compiler`` package that caused invalid code to be
1102 generated for generator expressions.
1103
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001104- The distutils version has been changed to 2.5.0. The change to
1105 keep it programmatically in sync with the Python version running
1106 the code (introduced in 2.5b3) has been reverted. It will continue
1107 to be maintained manually as static string literal.
1108
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001109- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001110 and this cannot be converted to the required C type, an exception is
1111 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001112 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001113
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001114- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001115 an exception.
1116
Tim Peterscbdd3502006-09-05 01:47:53 +00001117- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001118 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001119 workarounds for clocks with low resolution, to stop the code yielding
1120 duplicate UUIDs.
1121
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001122- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1123 before raising SystemExit, allowing IDLE to honor quit() and exit().
1124
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001125- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1126
Georg Brandl7a1af772006-08-14 21:55:28 +00001127- Patch #1536071: trace.py should now find the full module name of a
1128 file correctly even on Windows.
1129
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001130- logging's atexit hook now runs even if the rest of the module has
1131 already been cleaned up.
1132
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001133- Bug #1112549, fix DoS attack on cgi.FieldStorage.

1136 str(exception) raised an exception.
1137
Neil Schemenauer06ded092006-08-04 16:20:30 +00001138- Fix a bug in the ``compiler`` package that caused invalid code to be
1139 generated for nested functions.

1156 uses the _as_parameter_ attribute when objects are passed to foreign
1157 function calls. The ctypes version number was changed to 1.0.1.
1158
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001159- Bug #1530559, struct.pack raises TypeError where it used to convert.

Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001198- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1199
Tim Peters4643c2f2006-08-10 22:45:34 +00001200- Bug #1069160. Internal correctness changes were made to
1201 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1202 the documentation was changed to state that the return value
1203 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001206What's New in Python 2.5 beta 3?
1207================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001208
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001209*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001210
1211Core and builtins
1212-----------------
1213
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001214- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001215 returned a long (see PEP 353).
1216
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001217- Bug #1515471: string.replace() accepts character buffers again.
1218
Neal Norwitz07aadb12006-07-30 06:55:48 +00001219- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1220 This provides the proper warning for struct.pack().
1221 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1222
Neal Norwitz0d62a062006-07-30 06:53:31 +00001223- Patch #1531113: Fix augmented assignment with yield expressions.
1224 Also fix a SystemError when trying to assign to yield expressions.
1225
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001226- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1227 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1228 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1229 excessive filesystem operations during imports.
1230
Tim Petersbc24eee2006-07-27 01:14:53 +00001231- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1232 operations on signed longs that are formally undefined by C.
1233 Unfortunately, at least one compiler now cares about that, so complicated
1234 the code to make that compiler happy again.
1235
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001236- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1237
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001238- Patch #1232023: Stop including current directory in search
1239 path on Windows.
1240
Neal Norwitze1fdb322006-07-21 05:32:28 +00001241- Fix some potential crashes found with failmalloc.
1242
Neal Norwitze7563102006-07-17 01:00:16 +00001243- Fix warnings reported by Klocwork's static analysis tool.
1244
Neal Norwitz84be93b2006-07-16 01:50:38 +00001245- Bug #1512814, Fix incorrect lineno's when code within a function
1246 had more than 255 blank lines.
1247
Georg Brandl9dceedb2006-07-12 15:31:17 +00001248- Patch #1521179: Python now accepts the standard options ``--help`` and
1249 ``--version`` as well as ``/?`` on Windows.
1250
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001251- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001252 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001253 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001254
Tim Peters112aad32006-07-19 00:03:19 +00001255- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001256 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001257 new ``sys._current_frames()`` returns a dictionary with one entry,
1258 mapping the faux "thread id" 0 to the current frame.
1259
Ronald Oussoren3075e162006-07-25 20:28:55 +00001260- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001261
Ronald Oussoren3075e162006-07-25 20:28:55 +00001262
Neal Norwitza1f10902006-07-12 07:28:29 +00001263Library
1264-------
1265
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001266- Correction of patch #1455898: In the mbcs decoder, set final=False
1267 for stream decoder, but final=True for the decode function.
1268
Georg Brandl07fec3a2006-08-01 18:49:24 +00001269- os.urandom no longer masks unrelated exceptions like SystemExit or
1270 KeyboardInterrupt.
1271
Tim Peters4643c2f2006-08-10 22:45:34 +00001272- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001273 shutil.copytree on Windows
1274
Georg Brandle34ac7c2006-07-30 11:07:23 +00001275- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1276 refers to file descriptors, not file objects.
1277
Tim Peterscbdd3502006-09-05 01:47:53 +00001278- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001279 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001280 #1513611, and probably others.
1281
Georg Brandledd9b0d2006-07-29 09:33:26 +00001282- Bug #1441397: The compiler module now recognizes module and function
1283 docstrings correctly as it did in Python 2.4.
1284
Tim Peters6f681472006-07-27 23:44:37 +00001285- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1286 lost that tests are sorted by name before being run. This rarely
1287 matters for well-written tests, but can create baffling symptoms if
1288 side effects from one test to the next affect outcomes. ``DocTestFinder``
1289 has been changed to sort the list of tests it returns.
1290
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001291- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001292 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001293
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001294- Bug #978833: Really close underlying socket in _socketobject.close.
1295
Georg Brandldb232dc2006-08-20 13:15:43 +00001296- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1297 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001298
Georg Brandlcf0c1722006-07-26 07:23:32 +00001299- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1300 to recursive calls and call it with the failing package name.
1301
Martin v. Löwis0b483032006-07-25 09:53:12 +00001302- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1303
Georg Brandlc13c34c2006-07-24 14:09:56 +00001304- Patch #1515343: Fix printing of deprecated string exceptions with a
1305 value in the traceback module.
1306
Greg Ward48fae7a2006-07-23 16:05:51 +00001307- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1308
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001309- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1310
Brett Cannoncaebe222006-07-18 04:41:36 +00001311- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1312 argument tuple. For arguments where zero is illegal, the value is forced to
1313 the minimum value that is correct. This is to support an undocumented but
1314 common way people used to fill in inconsequential information in the time
1315 tuple pre-2.4.
1316
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001317- Patch #1220874: Update the binhex module for Mach-O.
1318
Barry Warsawb110bad2006-07-21 14:51:07 +00001319- The email package has improved RFC 2231 support, specifically for
1320 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1321 (name*0=<blah>) parameter continuations. This may change the types of
1322 values returned from email.message.Message.get_param() and friends.
1323 Specifically in some cases where non-encoded continuations were used,
1324 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1325 will just return the string (since non-encoded continuations don't have
1326 charset and language parts).
1327
1328 Also, whereas % values were decoded in all parameter continuations, they are
1329 now only decoded in encoded parameter parts.
1330
Ronald Oussoren3075e162006-07-25 20:28:55 +00001331- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1332
1333- Bug #1517996: IDLE now longer shows the default Tk menu when a
1334 path browser, class browser or debugger is the frontmost window on MacOS X
1335
Barry Warsaw00decd72006-07-27 23:43:15 +00001336- Patch #1520294: Support for getset and member descriptors in types.py,
1337 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1338 of an object against these built-in types and more importantly, for getting
1339 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001342Extension Modules
1343-----------------
1344
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001345- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1346 a socket operation on a socket with a timeout, the exception will be
1347 caught correctly. Previously, the exception was not caught.
1348
Thomas Heller1393d6a2006-07-28 21:43:20 +00001349- Patch #1529514: The _ctypes extension is now compiled on more
1350 openbsd target platforms.
1351
Tim Peters9cab5932006-07-28 00:30:00 +00001352- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1353 a memory leak, affecting pickles and deep copies.
1354
Tim Petersbc24eee2006-07-27 01:14:53 +00001355- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001356 Paul Eggert.
1357
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001358- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1359
Thomas Hellerce049a02006-07-14 17:51:14 +00001360- Patch #1521817: Index range checking on ctypes arrays containing
1361 exactly one element enabled again. This allows iterating over these
1362 arrays, without the need to check the array size before.
1363
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001364- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001365 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001366 /dev/null in certain cases; this is now fixed.
1367
Thomas Heller47d7a062006-07-12 08:43:47 +00001368- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1369 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001370
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001371- Because of a misspelled preprocessor symbol, ctypes was always
1372 compiled without thread support; this is now fixed.
1373
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001374- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1375 methods now allow their database parameter to be None as the
1376 sleepycat API allows.
1377
Matt Flemingec926502006-07-28 11:27:27 +00001378- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1379 bluetooth API compared with Linux and FreeBSD.
1380
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001381Tests
1382-----
1383
1384- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1385 how long the test file should take to play. Now accepts taking 2.93 secs
1386 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1387
Georg Brandl4793aa32006-07-28 18:31:39 +00001388- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1389 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1390 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001397Mac
1398---
1399
1400- PythonLauncher now works correctly when the path to the script contains
1401 characters that are treated specially by the shell (such as quotes).
1402
1403- Bug #1527397: PythonLauncher now launches scripts with the working directory
1404 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001405 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001406 expect.

1415-----------------
1416
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001417- Bug #1441486: The literal representation of -(sys.maxint - 1)
1418 again evaluates to a int object, not a long.
1419
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001420- Bug #1501934: The scope of global variables that are locally assigned
1421 using augmented assignment is now correctly determined.
1422
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001423- Bug #927248: Recursive method-wrapper objects can now safely
1424 be released.
1425
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001426- Bug #1417699: Reject locale-specific decimal point in float()
1427 and atof().
1428
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001429- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1430 omit a default "error" argument for NULL pointer. This allows
1431 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001432
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001433- Bug #1519018: 'as' is now validated properly in import statements.
1434
Neal Norwitz28746ab2006-07-09 22:14:42 +00001435- On 64 bit systems, int literals that use less than 64 bits are
1436 now ints rather than longs.
1437
Neal Norwitzed657552006-07-10 00:04:44 +00001438- Bug #1512814, Fix incorrect lineno's when code at module scope
1439 started after line 256.
1440
Tim Peters32a83612006-07-10 21:08:24 +00001441- New function ``sys._current_frames()`` returns a dict mapping thread
1442 id to topmost thread stack frame. This is for expert use, and is
1443 especially useful for debugging application deadlocks. The functionality
1444 was previously available in Fazal Majid's ``threadframe`` extension
1445 module, but it wasn't possible to do this in a wholly threadsafe way from
1446 an extension.

1452 VS 2003.
1453
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001454- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1455
Tim Peters32a83612006-07-10 21:08:24 +00001456- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001457 environment variable to be set in order to the SDK environment
1458 for finding the compiler, include files, etc.

1463
Thomas Woutersadd19112006-07-05 11:03:49 +00001464- string.Template() now correctly handles tuple-values. Previously,
1465 multi-value tuples would raise an exception and single-value tuples would
1466 be treated as the value they contain, instead.
1467
Martin v. Löwisede77f52006-07-03 13:01:35 +00001468- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001479
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001480- Bug #1514703: Only setup canvas window in turtle when the canvas
1481 is created.
1482
Martin v. Löwis7596e832006-07-01 15:33:37 +00001483- Bug #1513223: .close() of a _socketobj now releases the underlying
1484 socket again, which then gets closed as it becomes unreferenced.
1485

1493
Brett Cannon53ab5b72006-06-22 16:49:14 +00001494- Bug #1510580: The 'warnings' module improperly required that a Warning
1495 category be either a types.ClassType and a subclass of Warning. The proper
1496 check is just that it is a subclass with Warning as the documentation states.
1497
Georg Brandlad29e632006-06-21 17:45:17 +00001498- The compiler module now correctly compiles the new try-except-finally
1499 statement (bug #1509132).
1500
Neal Norwitz60373cd2006-06-22 06:30:50 +00001501- The wsgiref package is now installed properly on Unix.
1502

1504 shutdown when fileConfig() was called multiple times.
1505
Gerhard Häring762fbd32006-07-02 17:48:30 +00001506- The sqlite3 module did cut off data from the SQLite database at the first
1507 null character before sending it to a custom converter. This has been fixed
1508 now.
1509
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001510Extension Modules
1511-----------------
1512
Tim Peters112aad32006-07-19 00:03:19 +00001513- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1514 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1515 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001516
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001517- Assigning None to pointer type fields in ctypes structures possible
1518 overwrote the wrong fields, this is fixed now.
1519
1520- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1521 on non-Windows platforms.
1522
1523- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1524 integer or long, without range checking.
1525
1526- Patch #1517790: It is now possible to use custom objects in the ctypes
1527 foreign function argtypes sequence as long as they provide a from_param
1528 method, no longer is it required that the object is a ctypes type.
1529
1530- The '_ctypes' extension module now works when Python is configured
1531 with the --without-threads option.
1532
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001533- Bug #1513646: os.access on Windows now correctly determines write
1534 access, again.
1535
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001536- Bug #1512695: cPickle.loads could crash if it was interrupted with

1548
Tim Peters32a83612006-07-10 21:08:24 +00001549- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001550 Previously, the slight difference could cause compilation errors of the
1551 'zlib' module on systems with more than one version of zlib.
1552
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001553- The MSI compileall step was fixed to also support a TARGETDIR

1584Core and builtins
1585-----------------
1586
Georg Brandla56b9152006-06-19 06:35:54 +00001587- Patch #1507676: Error messages returned by invalid abstract object operations
1588 (such as iterating over an integer) have been improved and now include the
1589 type of the offending object to help with debugging.
1590
Brett Cannonea3912b2006-06-13 21:46:41 +00001591- Bug #992017: A classic class that defined a __coerce__() method that returned
1592 its arguments swapped would infinitely recurse and segfault the interpreter.
1593
Neal Norwitz909eb122006-06-12 02:13:21 +00001594- Fix the socket tests so they can be run concurrently.
1595
Neal Norwitzb9845e72006-06-12 02:11:18 +00001596- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001597 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001598
Brett Cannon22565aa2006-06-09 22:31:23 +00001599- Bug #532646: object.__call__() will continue looking for the __call__
1600 attribute on objects until one without one is found. This leads to recursion
1601 when you take a class and set its __call__ attribute to an instance of the
1602 class. Originally fixed for classic classes, but this fix is for new-style.
1603 Removes the infinite_rec_3 crasher.
1604
Georg Brandl24250812006-06-09 18:45:48 +00001605- The string and unicode methods startswith() and endswith() now accept
1606 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1607
Brett Cannonde3b0522006-06-08 17:00:45 +00001608- Buffer objects, at the C level, never used the char buffer
1609 implementation even when the char buffer for the wrapped object was
1610 explicitly requested (originally returned the read or write buffer).
1611 Now a TypeError is raised if the char buffer is not present but is
1612 requested.
1613
Georg Brandlddbaa662006-06-04 21:56:52 +00001614- Patch #1346214: Statements like "if 0: suite" are now again optimized
1615 away like they were in Python 2.4.
1616
Georg Brandlb7c8f542006-05-27 12:30:25 +00001617- Builtin exceptions are now full-blown new-style classes instead of
1618 instances pretending to be classes, which speeds up exception handling
1619 by about 80% in comparison to 2.5a2.
1620
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001621- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1622 Unicode 4.1.
1623
Georg Brandlf4ef1162006-05-26 18:03:31 +00001624- Patch #921466: sys.path_importer_cache is now used to cache valid and
1625 invalid file paths for the built-in import machinery which leads to
1626 fewer open calls on startup.
1627
Tim Peters696cf432006-05-24 21:10:40 +00001628- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1629 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1630 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1631 the number of input digits (it was and remains linear-time for bases
1632 2, 4, 8, 16 and 32).
1633
Tim Petersb713ec22006-05-23 18:45:30 +00001634- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1635 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1636 an integer close to ``sys.maxint``. This was repaired by patch
1637 #1335972, which also gives a nice speedup.
1638
Richard Jonescebbefc2006-05-23 18:28:17 +00001639- Patch #1337051: reduced size of frame objects.
1640
1641- PyErr_NewException now accepts a tuple of base classes as its
1642 "base" parameter.
1643
Richard Jones7c88dcc2006-05-23 10:37:38 +00001644- Patch #876206: function call speedup by retaining allocated frame
1645 objects.
1646
Georg Brandl7b90e162006-05-18 07:01:27 +00001647- Bug #1462152: file() now checks more thoroughly for invalid mode
1648 strings and removes a possible "U" before passing the mode to the
1649 C library function.
1650
Neal Norwitz1004a532006-05-15 07:17:23 +00001651- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1652
Neal Norwitz373f0a72006-05-15 07:04:36 +00001653- Bug #1487966: Fix SystemError with conditional expression in assignment
1654
Martin v. Löwis879768d2006-05-11 13:28:43 +00001655- WindowsError now has two error code attributes: errno, which carries
1656 the error values from errno.h, and winerror, which carries the error
1657 values from winerror.h. Previous versions put the winerror.h values
1658 (from GetLastError()) into the errno attribute.
1659
Martin v. Löwis77736712006-05-04 05:51:03 +00001660- Patch #1475845: Raise IndentationError for unexpected indent.
1661
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001662- Patch #1479181: split open() and file() from being aliases for each other.
1663
Tim Peters44bd9862006-06-01 13:49:23 +00001664- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1665 methods were always silently ignored by dictionaries when comparing keys.
1666 They are now passed through (except when using the C API function
1667 ``PyDict_GetItem()``, whose semantics did not change).
1668
1669- Bug #1456209: In some obscure cases it was possible for a class with a
1670 custom ``__eq__()`` method to confuse dict internals when class instances
1671 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1672 No, you don't have any code that did this ;-)

1680
Brett Cannon6ee7d012006-06-08 16:23:04 +00001681- Change binascii.hexlify to accept a read-only buffer instead of only a char
1682 buffer and actually follow its documentation.
1683

1685
Nick Coghlanc649ec52006-05-29 12:43:05 +00001686- Patch #1478788 (modified version): The functional extension module has
1687 been renamed to _functools and a functools Python wrapper module added.
1688 This provides a home for additional function related utilities that are
1689 not specifically about functional programming. See PEP 309.
1690
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001691- Patch #1493701: performance enhancements for struct module.

1699 enabled builds on Windows and systems with Posix threads support.
1700
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001701- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1702 (up to the system limit of 32K characters).
1703
1704- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1705 As a result, these functions now raise WindowsError instead of OSError.
1706
Tim Peters7a822da2006-05-25 21:50:17 +00001707- ``time.clock()`` on Win64 should use the high-performance Windows
1708 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1709 Windows platforms).
1710
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001711- Calling Tk_Init twice is refused if the first call failed as that
1712 may deadlock.
1713
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001714- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1715 accept it without potentially using an uninitialized pointer.
1716
1717- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1718 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

1728 results. It could previously incorrectly return 0 in some cases.
1729 Fixes SF bug 1493322 (pybsddb bug 1184012).
1730
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001731- bsddb: the bsddb.dbtables Modify method now raises the proper error and

1733 Fixes SF python patch/bug #1408584.
1734
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001735- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001736 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001737 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1738 database calls that would previously deadlock. [SF python bug #775414]

Georg Brandl2605ca82006-06-14 06:08:31 +00001764- Bug #1339007: Shelf objects now don't raise an exception in their
1765 __del__ method when initialization failed.
1766
Martin v. Löwisd8251432006-06-14 05:21:04 +00001767- Patch #1455898: The MBCS codec now supports the incremental mode for
1768 double-byte encodings.
1769
Tim Peters43898b42006-06-14 04:09:25 +00001770- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1771 guarantee that adjacent triples in the return list always describe
1772 non-adjacent blocks. Previously, a pair of matching blocks could end
1773 up being described by multiple adjacent triples that formed a partition
1774 of the matching pair.
1775
Greg Ward0e0c9f42006-06-11 16:24:11 +00001776- Bug #1498146: fix optparse to handle Unicode strings in option help,
1777 description, and epilog.
1778
Greg Wardd1c797e2006-06-11 14:42:41 +00001779- Bug #1366250: minor optparse documentation error.
1780
Greg Ward7f547402006-06-11 00:40:49 +00001781- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1782 clarify docs.
1783
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001784- The wsgiref package has been added to the standard library.
1785
Nick Coghlan676725d2006-06-08 13:54:49 +00001786- The functions update_wrapper() and wraps() have been added to the functools
1787 module. These make it easier to copy relevant metadata from the original
1788 function when writing wrapper functions.
1789
Tim Petersd6a9eef2006-06-05 01:48:21 +00001790- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1791 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001792
Martin v. Löwis3f767792006-06-04 19:36:28 +00001793- Patch #1359618: Speed up charmap encoder by using a trie structure
1794 for lookup.
1795
Tim Petersd609b1a2006-06-02 23:22:51 +00001796- The functions in the ``pprint`` module now sort dictionaries by key
1797 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1798 if and only if its display required more than one line, although that
1799 wasn't documented. The new behavior increases predictability; e.g.,
1800 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1801
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001802- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1803 (thanks for J. J. Lee).
1804
Georg Brandl2b330372006-05-28 20:23:12 +00001805- Patch #1496206: improve urllib2 handling of passwords with respect to
1806 default HTTP and HTTPS ports.
1807
George Yoshidaf3c65de2006-05-28 16:39:09 +00001808- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1809
Bob Ippolito7298f272006-05-23 18:43:47 +00001810- Patch #1281707: speed up gzip.readline.
1811
Georg Brandlb89316f2006-05-17 15:51:16 +00001812- Patch #1180296: Two new functions were added to the locale module:
1813 format_string() to get the effect of "format % items" but locale-aware,
1814 and currency() to format a monetary number with currency sign.
1815
Georg Brandle3a25832006-05-17 14:56:04 +00001816- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1817 and several features added, such as speed and geometry control.
1818
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001819- Patch #1488881: add support for external file objects in bz2 compressed
1820 tarfiles.
1821
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001822- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1823 stdout arguments, making it possible to redirect input and output
1824 for remote debugging.
1825
1826- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1827 a couple of issues, notably handling of long file names using the
1828 GNU LONGNAME extension.
1829
1830- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1831 new flag when ``name`` is already the name of an option flag.
1832
1833- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1834 package.
1835
1836- Patch #1472854: make the rlcompleter.Completer class usable on non-
1837 UNIX platforms.
1838
1839- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1840
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001841- Bug #1472827: correctly escape newlines and tabs in attribute values in
1842 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001872What's New in Python 2.5 alpha 2?
1873=================================
1874
1875*Release date: 27-APR-2006*
1876
1877Core and builtins
1878-----------------
1879
Thomas Heller1b046642006-04-18 18:51:06 +00001880- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1881 by converting these apis from macros into exported functions again:
1882
1883 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1884 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1885 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1886 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1887 PyRun_String Py_CompileString
1888
Martin v. Löwis45294a92006-04-18 06:24:08 +00001889- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1890
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001891- All uses of PyStructSequence_InitType have been changed to initialize
1892 the type objects only once, even if the interpreter is initialized
1893 multiple times.
1894
Neal Norwitz61546162006-04-14 05:20:28 +00001895- Bug #1454485, array.array('u') could crash the interpreter. This was
1896 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1897 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1898
1899- Py_UNICODE is unsigned. It was always documented as unsigned, but
1900 due to a bug had a signed value in previous versions.
1901
Tim Peters3a5e8b12006-04-11 01:44:07 +00001902- Patch #837242: ``id()`` of any Python object always gives a positive
1903 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1904 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001905 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001906 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001907
Tim Peters3a5e8b12006-04-11 01:44:07 +00001908 def __hash__(self):
1909 return id(self) # WRONG
1910
1911 because a hash result must be a (short) Python int but it was always
1912 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001913 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001914 was always usable as a hash value before this patch. That's no longer
1915 necessarily so.
1916
1917- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001918 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001919 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001920 #1454844)
1921
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001922- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1923 involving generators that have paused outside of any ``try`` or ``with``
1924 blocks. (In 2.5a1, a paused generator that was part of a reference
1925 cycle could not be garbage collected, regardless of whether it was
1926 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001927
Anthony Baxter51bcb682006-04-05 14:51:42 +00001928Extension Modules

1930
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001931- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1932 is a macro.
1933
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001934- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1935 fails with an error condition.
1936
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001937- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1938
1939- Bug #1117761: bsddb.*open() no longer raises an exception when using
1940 the cachesize parameter.
1941
1942- Bug #1149413: bsddb.*open() no longer raises an exception when using
1943 a temporary db (file=None) with the 'n' flag to truncate on open.
1944
1945- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1946 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001947
Armin Rigoa9017c32006-04-19 11:50:27 +00001948- Patch #1062014: AF_UNIX sockets under Linux have a special
1949 abstract namespace that is now fully supported.

Peter Astrand7d1d4362006-07-14 14:04:45 +00001954- Bug #1223937: subprocess.CalledProcessError reports the exit status
1955 of the process using the returncode attribute, instead of
1956 abusing errno.
1957
Tim Peters711bf302006-04-25 03:31:36 +00001958- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1959 a doctest to be skipped (the code is not run, and the expected output
1960 or exception is ignored).
1961
Nick Coghlanda2268f2006-04-24 04:37:15 +00001962- Fixed contextlib.nested to cope with exceptions being raised and
1963 caught inside exit handlers.
1964
Greg Wardab05edc2006-04-23 03:47:58 +00001965- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1966 hex, octal, or binary; add ``append_const`` action; keep going if
1967 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1968 added ``epilog`` for better help generation).
1969
Tim Peters21fbd572006-04-21 21:18:10 +00001970- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1971 called from a thread spawned as a side effect of importing a module.
1972
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001973- The pydoc module now supports documenting packages contained in
1974 .zip or .egg files.
1975
1976- The pkgutil module now has several new utility functions, such
1977 as ``walk_packages()`` to support working with packages that are either
1978 in the filesystem or zip files.
1979
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001980- The mailbox module can now modify and delete messages from
1981 mailboxes, in addition to simply reading them. Thanks to Gregory
1982 K. Johnson for writing the code, and to the 2005 Google Summer of
1983 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001984
Tim Petersc7605f22006-04-17 21:12:33 +00001985- The ``__del__`` method of class ``local`` in module ``_threading_local``
1986 returned before accomplishing any of its intended cleanup.
1987
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001988- Patch #790710: Add breakpoint command lists in pdb.
1989

1993
Anthony Baxtere29002c2006-04-12 12:07:31 +00001994- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1995 Windows. Bug #1469163.
1996
Phillip J. Eby47032112006-04-11 01:07:43 +00001997- The warnings, linecache, inspect, traceback, site, and doctest modules
1998 were updated to work correctly with modules imported from zipfiles or
1999 via other PEP 302 __loader__ objects.
2000
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00002001- Patch #1467770: Reduce usage of subprocess._active to processes which

2013
Martin v. Löwis4be4e652006-04-17 19:25:49 +00002014- The Makefile now has a reindent target, which runs reindent.py on
2015 the library.
2016
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002017- Patch #1470875: Building Python with MS Free Compiler

2022 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002023 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002024 CXX from --with-cxx-main, see description in README.
2025

2029
Tim Peters8931ff12006-05-13 23:28:20 +00002030- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2031 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2032 and "%zu" for unsigned integers of type ``size_t``.
2033
Anthony Baxter51bcb682006-04-05 14:51:42 +00002034Tests
2035-----
2036
Nick Coghlanda2268f2006-04-24 04:37:15 +00002037- test_contextlib now checks contextlib.nested can cope with exceptions
2038 being raised and caught inside exit handlers.
2039
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002040- test_cmd_line now checks operation of the -m and -c command switches
2041
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002042- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2043 it separately and by hand. It also wasn't cleaning up its changes to
2044 the current Decimal context.
2045
Thomas Woutersabd08882006-04-26 15:53:30 +00002046- regrtest.py now has a -M option to run tests that test the new limits of
2047 containers, on 64-bit architectures. Running these tests is only sensible
2048 on 64-bit machines with more than two gigabytes of memory. The argument
2049 passed is the maximum amount of memory for the tests to use.

2076-----------------
2077
Nick Coghlan43832302006-04-23 17:04:07 +00002078- PEP 338: -m command line switch now delegates to runpy.run_module
2079 allowing it to support modules in packages and zipfiles
2080
Martin v. Löwisc661b882006-04-20 04:54:23 +00002081- On Windows, .DLL is not an accepted file name extension for
2082 extension modules anymore; extensions are only found if they
2083 end in .PYD.
2084
Martin v. Löwisea62d252006-04-03 10:56:49 +00002085- Bug #1421664: sys.stderr.encoding is now set to the same value as
2086 sys.stdout.encoding.
2087
Neal Norwitz92e212f2006-04-03 04:48:37 +00002088- __import__ accepts keyword arguments.
2089
Georg Brandlccadf842006-03-31 18:54:53 +00002090- Patch #1460496: round() now accepts keyword arguments.
2091
Anthony Baxter262c00a2006-03-30 10:53:17 +00002092- Fixed bug #1459029 - unicode reprs were double-escaped.
2093
Hye-Shik Changd478f342006-03-23 12:32:36 +00002094- Patch #1396919: The system scope threads are reenabled on FreeBSD
2095 5.4 and later versions.
2096
Neal Norwitze98ccf62006-03-23 05:39:47 +00002097- Bug #1115379: Compiling a Unicode string with an encoding declaration
2098 now gives a SyntaxError.
2099
Georg Brandlabd1ff82006-03-18 07:59:59 +00002100- Previously, Python code had no easy way to access the contents of a
2101 cell object. Now, a ``cell_contents`` attribute has been added
2102 (closes patch #1170323).
2103
Tim Peterscf79aac2006-03-16 01:14:46 +00002104- Patch #1123430: Python's small-object allocator now returns an arena to
2105 the system ``free()`` when all memory within an arena becomes unused
2106 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2107 freed. Some applications will see a drop in virtual memory size now,
2108 especially long-running applications that, from time to time, temporarily
2109 use a large number of small objects. Note that when Python returns an
2110 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002111 platform C library will in turn return that memory to the operating system.
2112 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002113 appears to be effective at least on Microsoft C and gcc-based systems.
2114 Thanks to Evan Jones for hard work and patience.
2115
Georg Brandl533ff6f2006-03-08 18:09:27 +00002116- Patch #1434038: property() now uses the getter's docstring if there is
2117 no "doc" argument given. This makes it possible to legitimately use
2118 property() as a decorator to produce a read-only property.
2119
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002120- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2121 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2122 of requiring an int or long in slicing and a few other contexts, enabling
2123 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2124
Neal Norwitz995acdf2006-03-07 05:01:00 +00002125- Fixed various bugs reported by Coverity's Prevent tool.
2126
Brett Cannonbf364092006-03-01 04:25:17 +00002127- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2128 new exception base class, BaseException, which has a new message attribute.
2129 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2130 Raising a string exception now raises a DeprecationWarning.
2131
Thomas Woutersfb609f42006-02-28 16:37:25 +00002132- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2133 explicitly relative, using 'from .module import name' to mean 'from the same
2134 package as this module is in. Imports without dots still default to the
2135 old relative-then-absolute, unless 'from __future__ import
2136 absolute_import' is used.
2137
Brett Cannona7446e32006-02-27 23:39:10 +00002138- Properly check if 'warnings' raises an exception (usually when a filter set
2139 to "error" is triggered) when raising a warning for raising string
2140 exceptions.
2141
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002142- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002143 The name was removed from Include/code.h.
2144
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002145- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002146
Guido van Rossum1968ad32006-02-25 22:38:04 +00002147- Patch 1433928:
2148 - The copy module now "copies" function objects (as atomic objects).
2149 - dict.__getitem__ now looks for a __missing__ hook before raising
2150 KeyError.
2151
Tim Peters84ef21c2006-02-28 20:39:06 +00002152- PEP 343: with statement implemented. Needs ``from __future__ import
2153 with_statement``. Use of 'with' as a variable will generate a warning.
2154 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002155 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002156 The following objects have __context__ methods:
2157 - The built-in file type.
2158 - The thread.LockType type.
2159 - The following types defined by the threading module:
2160 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2161 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002162
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002163- Fix the encodings package codec search function to only search
2164 inside its own package. Fixes problem reported in patch #1433198.
2165
2166 Note: Codec packages should implement and register their own
2167 codec search function. PEP 100 has the details.
2168
Tim Peters9ea89d22006-06-04 03:26:02 +00002169- PEP 353: Using ``Py_ssize_t`` as the index type.
2170
2171- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2172 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2173 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2174 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2175 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002176
Neal Norwitzfc76d632006-01-10 06:03:13 +00002177- Patch #1400181, fix unicode string formatting to not use the locale.
2178 This is how string objects work. u'%f' could use , instead of .
2179 for the decimal point. Now both strings and unicode always use periods.
2180
Neal Norwitz671b9e32006-01-09 07:07:12 +00002181- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2182 configure would break checking curses.h.
2183
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002184- Bug #959576: The pwd module is now builtin. This allows Python to be
2185 built on UNIX platforms without $HOME set.
2186
Neal Norwitzc10978f2005-12-19 06:07:16 +00002187- Bug #1072182, fix some potential problems if characters are signed.
2188
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002189- Bug #889500, fix line number on SyntaxWarning for global declarations.
2190
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002191- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2192
Neal Norwitze7214a12005-12-18 05:03:17 +00002193- Support for converting hex strings to floats no longer works.
2194 This was not portable. float('0x3') now raises a ValueError.
2195
Barry Warsaw2a38a862005-12-18 01:27:35 +00002196- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002197 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002198 is now displayed in interactive prompt banner.
2199
Georg Brandlfa166682005-12-17 21:45:17 +00002200- Implementation of PEP 341 - Unification of try/except and try/finally.
2201 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002202 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002203
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002204- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2205 now encodes backslash correctly.
2206
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002207- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2208
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002209- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002210 and long longs.
2211
Neal Norwitz67715f02005-11-09 06:59:35 +00002212- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002213 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002214 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002215
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002216- Replaced most Unicode charmap codecs with new ones using the
2217 new Unicode translate string feature in the builtin charmap
2218 codec; the codecs were created from the mapping tables available
2219 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2220 encodings now include a mapping for the Apple logo)
2221
Tim Peterse3547fd2005-12-16 23:13:57 +00002222- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002223
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002224- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002225
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002226- A new AST parser implementation was completed. The abstract
2227 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002228 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002229
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002230- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002231 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2232
Neal Norwitz708e51a2005-10-03 04:48:15 +00002233- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2234
Neal Norwitz11bd1192005-10-03 00:54:56 +00002235- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2236 Provide a warning when a directory is passed on the command line.
2237
Neal Norwitz40d37812005-10-02 01:48:49 +00002238- Fix segfault with invalid coding.
2239
2240- SF bug #772896: unknown encoding results in MemoryError.
2241
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002242- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002243 supported a __len__() method which evaluated to False when the iterator
2244 was empty.
2245
Guido van Rossum630db602005-09-20 18:49:54 +00002246- On 64-bit platforms, when __len__() returns a value that cannot be
2247 represented as a C int, raise OverflowError.
2248
Skip Montanarof8948ca2005-09-19 03:54:46 +00002249- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002250 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002251
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002252- SF bug #893549: parsing keyword arguments was broken with a few format
2253 codes.
2254
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002255- Changes donated by Elemental Security to make it work on AIX 5.3
2256 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2257 bug #105470: test_pwd fails on 64bit system (Opteron).
2258
Guido van Rossum539c6622005-09-14 17:49:54 +00002259- Changes donated by Elemental Security to make it work on HP-UX 11 on
2260 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2261
Georg Brandl4550b8d2005-08-26 06:43:52 +00002262- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002263 (fixes bug #1119418).
2264
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002265- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2266
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002267- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2268 exceptions that cause a function to exit.
2269
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002270- The implementation of set() and frozenset() was revised to use its
2271 own internal data structure. Memory consumption is reduced by 1/3
2272 and there are modest speed-ups as well. The API is unchanged.
2273
Tim Petersde7990b2005-07-17 23:45:23 +00002274- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2275
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002276- SF bug #1229429: PyObject_CallMethod failed to decrement some
2277 reference counts in some error exit cases.
2278
Tim Petersecc6e6a2005-07-10 22:30:55 +00002279- SF bug #1185883: Python's small-object memory allocator took over
2280 a block managed by the platform C library whenever a realloc specified
2281 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002282 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002283 portable way to copy data from the C-managed block into Python's
2284 small-object space without risking a memory fault. Python's small-object
2285 realloc now leaves such blocks under the control of the platform C
2286 realloc.
2287
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002288- SF bug #1232517: An overflow error was not detected properly when
2289 attempting to convert a large float to an int in os.utime().
2290
Raymond Hettinger3296e692005-06-29 23:29:56 +00002291- SF bug #1224347: hex longs now print with lowercase letters just
2292 like their int counterparts.
2293
Michael W. Hudson188d4362005-06-20 16:52:57 +00002294- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2295 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2296 interpreter states; back out that fix and do a better job (see
2297 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2298 for a longer write-up of the problem).
2299
Michael W. Hudsondf888462005-06-03 14:41:55 +00002300- SF patch #1180995: marshal now uses a binary format by default when
2301 serializing floats.
2302
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002303- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2304 the routines that promise to produce IEEE 754 binary representations
2305 of floats now simply copy bytes around.
2306
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002307- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2308 278.
2309
Brett Cannonc3647ac2005-04-26 03:45:26 +00002310- patch #1109424: int, long, float, complex, and unicode now check for the
2311 proper magic slot for type conversions when subclassed. Previously the
2312 magic slot was ignored during conversion. Semantics now match the way
2313 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002314 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002315 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002316 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002317
Barry Warsawc8d907c2005-04-19 23:43:40 +00002318- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2319 NULL, now raise an AttributeError when attempting to set or delete the
2320 attribute. Previously a TypeError was raised, but this was inconsistent
2321 with the equivalent pure-Python implementation.
2322
Michael W. Hudson774479c2005-04-18 08:46:17 +00002323- It is now safe to call PyGILState_Release() before
2324 PyEval_InitThreads() (note that if there is reason to believe there
2325 are multiple threads around you still must call PyEval_InitThreads()
2326 before using the Python API; this fix is for extension modules that
2327 have no way of knowing if Python is multi-threaded yet).
2328
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002329- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2330 disabled caused a crash.
2331
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002332- Bug #1165306: instancemethod_new allowed the creation of a method
2333 with im_class == im_self == NULL, which caused a crash when called.
2334
Tim Petersecc6e6a2005-07-10 22:30:55 +00002335- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002336 fixes the crash seen in bug #1165761
2337
Raymond Hettinger96229b12005-03-11 06:49:40 +00002338- Added two new builtins, any() and all().

Tim Petersf4e69282006-02-27 17:15:31 +00002380- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2381 current thread state when the auto-GIL-state machinery knows about
2382 it (since the thread state is being deleted, continuing to remember it
2383 can't help, but can hurt if another thread happens to get created with
2384 the same thread id).

2592 in attribute values.
2593
Anthony Baxterc51ee692006-04-01 00:57:31 +00002594- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002595 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002596 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002597 module will not be built.

Tim Petersc17976e2006-04-01 00:26:53 +00002599- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2600 aren't officially supported here, and trying to use them will probably

2622
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002623- email 4.0 package now integrated. This is largely the same as the email 3.0
2624 package that was included in Python 2.3, except that PEP 8 module names are
2625 now used (e.g. mail.message instead of email.Message). The MIME classes
2626 have been moved to a subpackage (e.g. email.mime.text instead of
2627 email.MIMEText). The old names are still supported for now. Several
2628 deprecated Message methods have been removed and lots of bugs have been
2629 fixed. More details can be found in the email package documentation.

2632 (a subclass of tuple) that provides incremental decoders and encoders
2633 (a way to use stateful codecs without the stream API). Python functions
2634 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2635 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2636 have been added.

2639 a ValueError instead of a StopIteration now (like file and cString.String do).
2640 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2641 called before (like file and StringIO.StringIO do).

Tim Peterse3547fd2005-12-16 23:13:57 +00002715 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2716 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2717 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2718 Ronald L. Rivest offered this advice for Python:
2719
2720 "The consensus of researchers in this area (at least as
2721 expressed at the NIST Hash Function Workshop 10/31/05),
2722 is that SHA-256 is a good choice for the time being, but
2723 that research should continue, and other alternatives may
2724 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002725
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002726- Added a subset of Fredrik Lundh's ElementTree package. Available

2882
Raymond Hettingerbab41432005-02-05 01:31:19 +00002883- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2884
Guido van Rossumd0641422005-02-03 15:01:24 +00002885- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2886 disables recursive traversal through instance attributes, which can
2887 be exploited in various ways.
2888
Tim Peterse3547fd2005-12-16 23:13:57 +00002889- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002890 flags on the HTTP listening socket.
2891
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002892- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2893 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2894
Fred Drakefbdeaad2006-07-29 16:56:15 +00002895- Patches #893642, #1039083: add allow_none, encoding arguments to
2896 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.

Thomas Hellerd6c6e222005-01-20 19:20:16 +00002900- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2901
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002902- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2903
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002904- Enhancements to the csv module:
2905
2906 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002907 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002908 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002909 + Dialect parameter parsing has been re-implemented to improve error
2910 reporting.
2911 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2912 dictates.
2913 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002914 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002915 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002916 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2917 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002918 + reader now allows \r characters to be quoted (previously it only allowed
2919 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002920 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002921 + Dialect classes passed to the module are no longer instantiated by
2922 the module before being parsed (the former validation scheme required
2923 this, but the mechanism was unreliable).
2924 + The dialect registry now contains instances of the internal
2925 C-coded dialect type, rather than references to python objects.
2926 + the internal c-coded dialect type is now immutable.
2927 + register_dialect now accepts the same keyword dialect specifications
2928 as the reader and writer, allowing the user to register dialects
2929 without first creating a dialect class.
2930 + a configurable limit to the size of parsed fields has been added -
2931 previously, an unmatched quote character could result in the entire
2932 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002933 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002934 the parser field size limit (returning the former limit). The initial
2935 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002936 + A line_num attribute has been added to the reader object, which tracks
2937 the number of lines read from the source iterator. This is not
2938 the same as the number of records returned, as records can span
2939 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002940 + reader and writer objects were not being registered with the cyclic-GC.
2941 This has been fixed.
2942
Brett Cannone6539c42005-01-08 02:43:53 +00002943- _DummyThread objects in the threading module now delete self.__block that is
2944 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2945 lock primitives tend to be limited in number and thus should not be wasted on
2946 a _DummyThread object. Fixes bug #1089632.
2947
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002948- The imghdr module now detects Exif files.
2949
Raymond Hettinger6065d322004-12-20 23:51:53 +00002950- StringIO.truncate() now correctly adjusts the size attribute.
2951 (Bug #951915).
2952
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002953- locale.py now uses an updated locale alias table (built using
2954 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2955 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002956 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002957
Raymond Hettinger3557f422004-12-07 12:02:02 +00002958- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2959
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002960- the pickle module no longer accepts the deprecated None option in the
2961 args tuple returned by __reduce__().
2962
Brett Cannon84667c02004-12-07 03:25:18 +00002963- optparse now optionally imports gettext. This allows its use in setup.py.
2964
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002965- the pickle module no longer uses the deprecated bin parameter.
2966
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002967- the shelve module no longer uses the deprecated binary parameter.
2968
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002969- the pstats module no longer uses the deprecated ignore() method.
2970
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002971- the filecmp module no longer uses the deprecated use_statcache argument.
2972
Raymond Hettinger664347b2004-12-04 21:21:53 +00002973- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2974 extended or overridden by subclasses. Formerly, the subclassed method would
2975 be ignored by the rest of the module. (Bug #1078905).
2976
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002977- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002978 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002979
Walter Dörwald36733692004-12-22 12:50:50 +00002980- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2981 once when a size argument is given. This prevents a buffer overflow in the
2982 tokenizer with very long source lines.
2983
Barry Warsaw538561e2006-01-01 21:48:54 +00002984- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2985 immediately after creating the object, without any intervening
2986 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002987
Skip Montanaro05885812005-01-16 20:48:27 +00002988- The reconvert.quote function can now emit triple-quoted strings. The
2989 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002990
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002991- ``UserString.MutableString`` now supports negative indices in
2992 ``__setitem__`` and ``__delitem__``
2993
Greg Ward40407942005-03-05 02:53:17 +00002994- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2995 correctly.
2996
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002997- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2998 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2999 character even if the user has passed a size parameter to get a proper
3000 line ending. Remove the special handling of a "\r\n" that has been split
3001 between two lines.
3002
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003003- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3004 about illegal code points. The codec now supports PEP 293 style error
3005 handlers.
3006
Walter Dörwald78a78b02005-09-01 12:04:29 +00003007- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003008 from the input stream, so that the output is a byte string in the correct
3009 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003010
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003011- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3012 considering it exactly like a '*'.
3013
Walter Dörwald007f8df2005-10-09 19:42:27 +00003014- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3015 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003016
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003017- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3018
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003019- Patch #1413711: Certain patterns of differences were making difflib
3020 touch the recursion limit.
3021
Walter Dörwald58917a62006-03-31 15:26:22 +00003022- Bug #947906: An object oriented interface has been added to the calendar
3023 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003024 called as a script (e.g. via ``python -mcalendar``). Localized month and
3025 weekday names can be ouput (even if an exotic encoding is used) using
3026 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003027
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003028Build

3035
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003036- Build support for Win64-AMD64 was added.
3037
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003038- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3039
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003040- Patch #881820: look for openpty and forkpty also in libbsd.
3041
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003042- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3043 The zlib module is now builtin on Windows.
3044
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003045- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3046
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003047- Bug #1189330: configure did not correctly determine the necessary
3048 value of LINKCC if python was built with GCC 4.0.
3049
Trent Mick8321b422005-07-26 02:29:21 +00003050- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3051 vulnerability in zlib 1.2.1 and 1.2.2.
3052
Brett Cannon08cd5982005-04-24 22:26:38 +00003053- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3054 flags that change binary compatibility. Changes were also made to
3055 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003056 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003057
Bob Ippolitoed233462005-03-29 13:47:59 +00003058- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3059 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3060 no longer exists). This configure patch makes things right.
3061
Martin v. Löwise2713be2005-03-08 15:03:08 +00003062- Bug #1158607: Build with --disable-unicode again.
3063
Brett Cannon46d96232005-02-16 00:07:19 +00003064- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3065 defined. Discovered as a result of not being able to build on OS X.
3066
Brett Cannon516592f2004-12-07 00:42:59 +00003067- setup.py now uses the directories specified in LDFLAGS using the -L option
3068 and in CPPFLAGS using the -I option for adding library and include
3069 directories, respectively, for compiling extension modules against. This has
3070 led to the core being compiled using the values in CPPFLAGS. It also removes
3071 the need for the special-casing of both DarwinPorts and Fink for darwin since
3072 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3073 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3074 Fink, ``-I/opt/local/include`` for DarwinPorts).
3075
Brett Cannon43802422005-02-10 20:48:03 +00003076- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3077 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3078 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3079 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003081C API
3082-----
3083
Tim Petersc9d78aa2006-03-26 23:27:58 +00003084- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3085 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3086 is obtained via the ``PyObject_`` family, it must be released via the
3087 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3088 always been officially true, but when Python's small-object allocator was
3089 introduced, an attempt was made to cater to a few extension modules
3090 discovered at the time that obtained memory via ``PyObject_New`` but
3091 released it via ``PyMem_DEL``. It's years later, and if such code still
3092 exists it will fail now (probably with segfaults, but calling wrong
3093 low-level memory management functions can yield many symptoms).
3094
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003095- Added a C API for set and frozenset objects.
3096

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003099- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3100 mapping argument now. This string is used as a mapping table. Byte values
3101 greater than the length of the string and 0xFFFE are treated as undefined
3102 mappings.
