583 contain a valid HTTP status line.

600 be equal to calling getsockname() on the server's socket. Fixed by patch
601 #1545011.
602
Thomas Heller8bf469d2007-03-09 20:48:57 +0000603- Bug #1651235: When a tuple was passed to a ctypes function call,
604 Python would crash instead of raising an error.
Georg Brandl1f215782006-09-24 10:36:08 +0000605

Georg Brandld59ea472007-03-08 18:37:35 +0000613- unittest now verifies more of its assumptions. In particular, TestCase
614 and TestSuite subclasses (not instances) are no longer accepted in
615 TestSuite.addTest(). This should cause no incompatibility since it
616 never made sense with ordinary subclasses -- the failure just occurred
617 later, with a more cumbersome exception.

Neal Norwitzff4b63b2006-08-04 04:50:21 +0000971
972Core and builtins
973-----------------
974
Neal Norwitz24b6f202006-09-05 04:43:56 +0000975- Fix infinite recursion when subclassing long and overriding __hash__.
976
977- Fix concatenation (+=) of long strings.
978
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000979- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000980 compared equal or unequal to a string and a UnicodeDecodeError
981 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000982
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000983 Instead, the equal (==) and unequal (!=) comparison operators will
984 now issue a UnicodeWarning and interpret the two objects as
985 unequal. The UnicodeWarning can be filtered as desired using
986 the warning framework, e.g. silenced completely, turned into an
987 exception, logged, etc.
988
989 Note that compare operators other than equal and unequal will still
990 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000991
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000992- Fix segfault when doing string formatting on subclasses of long.
993
994- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
995 with new-style classes.
996
997- Fix bug related to __len__ functions returning negative values with
998 classic classes.
999
1000- Patch #1538606, Fix __index__() clipping. There were some problems
1001 discovered with the API and how integers that didn't fit into Py_ssize_t
1002 were handled. This patch attempts to provide enough alternatives
1003 to effectively use __index__.
1004
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001005- Bug #1536021: __hash__ may now return long int; the final hash
1006 value is obtained by invoking hash on the long int.
1007
Thomas Hellerab1049c2006-08-08 17:37:00 +00001008- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1009
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001010- Bug #1535165: fixed a segfault in input() and raw_input() when
1011 sys.stdin is closed.
1012
Thomas Heller74d36f02006-08-04 18:17:40 +00001013- On Windows, the PyErr_Warn function is now exported from
1014 the Python dll again.
1015
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001016- Bug #1191458: tracing over for loops now produces a line event
1017 on each iteration. Fixing this problem required changing the .pyc
1018 magic number. This means that .pyc files generated before 2.5c1
1019 will be regenerated.
1020
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001021- Bug #1333982: string/number constants were inappropriately stored
1022 in the byte code and co_consts even if they were not used, ie
1023 immediately popped off the stack.
1024
Georg Brandle9462c72006-08-04 18:03:37 +00001025- Fixed a reference-counting problem in property().

1028Library
1029-------
1030
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001031- Fix a bug in the ``compiler`` package that caused invalid code to be
1032 generated for generator expressions.
1033
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001034- The distutils version has been changed to 2.5.0. The change to
1035 keep it programmatically in sync with the Python version running
1036 the code (introduced in 2.5b3) has been reverted. It will continue
1037 to be maintained manually as static string literal.
1038
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001039- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001040 and this cannot be converted to the required C type, an exception is
1041 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001042 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001043
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001044- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001045 an exception.
1046
Tim Peterscbdd3502006-09-05 01:47:53 +00001047- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001048 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001049 workarounds for clocks with low resolution, to stop the code yielding
1050 duplicate UUIDs.
1051
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001052- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1053 before raising SystemExit, allowing IDLE to honor quit() and exit().
1054
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001055- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1056
Georg Brandl7a1af772006-08-14 21:55:28 +00001057- Patch #1536071: trace.py should now find the full module name of a
1058 file correctly even on Windows.
1059
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001060- logging's atexit hook now runs even if the rest of the module has
1061 already been cleaned up.
1062
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001063- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001064
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001065- Bug #1531405, format_exception no longer raises an exception if
1066 str(exception) raised an exception.
1067
Neil Schemenauer06ded092006-08-04 16:20:30 +00001068- Fix a bug in the ``compiler`` package that caused invalid code to be
1069 generated for nested functions.

1080 raises the correct exceptions.
1081
Thomas Heller1ce433e2006-08-14 16:20:04 +00001082- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1083 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1084
Thomas Heller86720042006-08-14 11:17:48 +00001085- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1086 uses the _as_parameter_ attribute when objects are passed to foreign
1087 function calls. The ctypes version number was changed to 1.0.1.
1088
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001089- Bug #1530559, struct.pack raises TypeError where it used to convert.

Neal Norwitza1f10902006-07-12 07:28:29 +00001140
1141Core and builtins
1142-----------------
1143
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001144- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001145 returned a long (see PEP 353).
1146
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001147- Bug #1515471: string.replace() accepts character buffers again.
1148
Neal Norwitz07aadb12006-07-30 06:55:48 +00001149- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1150 This provides the proper warning for struct.pack().
1151 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1152
Neal Norwitz0d62a062006-07-30 06:53:31 +00001153- Patch #1531113: Fix augmented assignment with yield expressions.
1154 Also fix a SystemError when trying to assign to yield expressions.
1155
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001156- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1157 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1158 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1159 excessive filesystem operations during imports.
1160
Tim Petersbc24eee2006-07-27 01:14:53 +00001161- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1162 operations on signed longs that are formally undefined by C.
1163 Unfortunately, at least one compiler now cares about that, so complicated
1164 the code to make that compiler happy again.
1165
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001166- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1167

1169 path on Windows.
1170
Neal Norwitze1fdb322006-07-21 05:32:28 +00001171- Fix some potential crashes found with failmalloc.
1172
Neal Norwitze7563102006-07-17 01:00:16 +00001173- Fix warnings reported by Klocwork's static analysis tool.

1176 had more than 255 blank lines.
1177
Georg Brandl9dceedb2006-07-12 15:31:17 +00001178- Patch #1521179: Python now accepts the standard options ``--help`` and
1179 ``--version`` as well as ``/?`` on Windows.
1180
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001181- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001182 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001183 This means that .pyc files generated before 2.5b3 will be regenerated.

Tim Peters112aad32006-07-19 00:03:19 +00001185- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001186 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001187 new ``sys._current_frames()`` returns a dictionary with one entry,
1188 mapping the faux "thread id" 0 to the current frame.

1194-------
1195
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001196- Correction of patch #1455898: In the mbcs decoder, set final=False
1197 for stream decoder, but final=True for the decode function.
1198
Georg Brandl07fec3a2006-08-01 18:49:24 +00001199- os.urandom no longer masks unrelated exceptions like SystemExit or
1200 KeyboardInterrupt.
1201
Tim Peters4643c2f2006-08-10 22:45:34 +00001202- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001203 shutil.copytree on Windows
1204
Georg Brandle34ac7c2006-07-30 11:07:23 +00001205- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1206 refers to file descriptors, not file objects.
1207
Tim Peterscbdd3502006-09-05 01:47:53 +00001208- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001209 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001210 #1513611, and probably others.
1211
Georg Brandledd9b0d2006-07-29 09:33:26 +00001212- Bug #1441397: The compiler module now recognizes module and function
1213 docstrings correctly as it did in Python 2.4.
1214
Tim Peters6f681472006-07-27 23:44:37 +00001215- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1216 lost that tests are sorted by name before being run. This rarely
1217 matters for well-written tests, but can create baffling symptoms if
1218 side effects from one test to the next affect outcomes. ``DocTestFinder``
1219 has been changed to sort the list of tests it returns.
1220
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001221- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001222 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001223
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001224- Bug #978833: Really close underlying socket in _socketobject.close.
1225
Georg Brandldb232dc2006-08-20 13:15:43 +00001226- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1227 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001228
Georg Brandlcf0c1722006-07-26 07:23:32 +00001229- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1230 to recursive calls and call it with the failing package name.
1231
Martin v. Löwis0b483032006-07-25 09:53:12 +00001232- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1233
Georg Brandlc13c34c2006-07-24 14:09:56 +00001234- Patch #1515343: Fix printing of deprecated string exceptions with a
1235 value in the traceback module.
1236
Greg Ward48fae7a2006-07-23 16:05:51 +00001237- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1238
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001239- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1240
Brett Cannoncaebe222006-07-18 04:41:36 +00001241- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1242 argument tuple. For arguments where zero is illegal, the value is forced to
1243 the minimum value that is correct. This is to support an undocumented but
1244 common way people used to fill in inconsequential information in the time
1245 tuple pre-2.4.
1246
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001247- Patch #1220874: Update the binhex module for Mach-O.
1248
Barry Warsawb110bad2006-07-21 14:51:07 +00001249- The email package has improved RFC 2231 support, specifically for
1250 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1251 (name*0=<blah>) parameter continuations. This may change the types of
1252 values returned from email.message.Message.get_param() and friends.
1253 Specifically in some cases where non-encoded continuations were used,
1254 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1255 will just return the string (since non-encoded continuations don't have
1256 charset and language parts).
1257
1258 Also, whereas % values were decoded in all parameter continuations, they are
1259 now only decoded in encoded parameter parts.
1260
Ronald Oussoren3075e162006-07-25 20:28:55 +00001261- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1262
1263- Bug #1517996: IDLE now longer shows the default Tk menu when a
1264 path browser, class browser or debugger is the frontmost window on MacOS X
1265
Barry Warsaw00decd72006-07-27 23:43:15 +00001266- Patch #1520294: Support for getset and member descriptors in types.py,
1267 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1268 of an object against these built-in types and more importantly, for getting
1269 their docstrings printed in the interactive interpreter's help() function.

1273-----------------
1274
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001275- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1276 a socket operation on a socket with a timeout, the exception will be
1277 caught correctly. Previously, the exception was not caught.
1278
Thomas Heller1393d6a2006-07-28 21:43:20 +00001279- Patch #1529514: The _ctypes extension is now compiled on more
1280 openbsd target platforms.
1281
Tim Peters9cab5932006-07-28 00:30:00 +00001282- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1283 a memory leak, affecting pickles and deep copies.
1284
Tim Petersbc24eee2006-07-27 01:14:53 +00001285- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1287
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001288- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1289
Thomas Hellerce049a02006-07-14 17:51:14 +00001290- Patch #1521817: Index range checking on ctypes arrays containing
1291 exactly one element enabled again. This allows iterating over these
1292 arrays, without the need to check the array size before.
1293
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001294- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001295 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001296 /dev/null in certain cases; this is now fixed.
1297
Thomas Heller47d7a062006-07-12 08:43:47 +00001298- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1299 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001300
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001301- Because of a misspelled preprocessor symbol, ctypes was always
1302 compiled without thread support; this is now fixed.
1303
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001304- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1305 methods now allow their database parameter to be None as the
1306 sleepycat API allows.
1307
Matt Flemingec926502006-07-28 11:27:27 +00001308- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1309 bluetooth API compared with Linux and FreeBSD.
1310
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001311Tests
1312-----
1313
1314- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1315 how long the test file should take to play. Now accepts taking 2.93 secs
1316 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1317
Georg Brandl4793aa32006-07-28 18:31:39 +00001318- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1319 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1320 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001327Mac
1328---
1329
1330- PythonLauncher now works correctly when the path to the script contains
1331 characters that are treated specially by the shell (such as quotes).
1332
1333- Bug #1527397: PythonLauncher now launches scripts with the working directory
1334 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001335 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001336 expect.

1345-----------------
1346
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001347- Bug #1441486: The literal representation of -(sys.maxint - 1)
1348 again evaluates to a int object, not a long.
1349
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001350- Bug #1501934: The scope of global variables that are locally assigned
1351 using augmented assignment is now correctly determined.
1352
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001353- Bug #927248: Recursive method-wrapper objects can now safely
1354 be released.
1355
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001356- Bug #1417699: Reject locale-specific decimal point in float()
1357 and atof().
1358
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001359- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1360 omit a default "error" argument for NULL pointer. This allows
1361 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001362
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001363- Bug #1519018: 'as' is now validated properly in import statements.
1364
Neal Norwitz28746ab2006-07-09 22:14:42 +00001365- On 64 bit systems, int literals that use less than 64 bits are
1366 now ints rather than longs.
1367
Neal Norwitzed657552006-07-10 00:04:44 +00001368- Bug #1512814, Fix incorrect lineno's when code at module scope
1369 started after line 256.
1370
Tim Peters32a83612006-07-10 21:08:24 +00001371- New function ``sys._current_frames()`` returns a dict mapping thread
1372 id to topmost thread stack frame. This is for expert use, and is
1373 especially useful for debugging application deadlocks. The functionality
1374 was previously available in Fazal Majid's ``threadframe`` extension
1375 module, but it wasn't possible to do this in a wholly threadsafe way from
1376 an extension.

1385
Tim Peters32a83612006-07-10 21:08:24 +00001386- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001387 environment variable to be set in order to the SDK environment
1388 for finding the compiler, include files, etc.

1393
Thomas Woutersadd19112006-07-05 11:03:49 +00001394- string.Template() now correctly handles tuple-values. Previously,
1395 multi-value tuples would raise an exception and single-value tuples would
1396 be treated as the value they contain, instead.
1397
Martin v. Löwisede77f52006-07-03 13:01:35 +00001398- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1400
Martin v. Löwis45482392006-07-03 12:28:58 +00001401- Bug #1267547: Put proper recursive setup.py call into the
1402 spec file generated by bdist_rpm.
1403
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001404- Bug #1514693: Update turtle's heading when switching between
1405 degrees and radians.
1406
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001407- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001408 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001409
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001410- Bug #1514703: Only setup canvas window in turtle when the canvas
1411 is created.
1412
Martin v. Löwis7596e832006-07-01 15:33:37 +00001413- Bug #1513223: .close() of a _socketobj now releases the underlying
1414 socket again, which then gets closed as it becomes unreferenced.
1415
Fred Drake10497c82006-06-29 02:57:48 +00001416- Bug #1504333: Make sgmllib support angle brackets in quoted
1417 attribute values.
1418
1419- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1420 sgmllib ('[' and ']' were not accepted).
1421
Georg Brandl1be63af2006-06-28 20:23:25 +00001422- Fix a bug in the turtle module's end_fill function.
1423
Brett Cannon53ab5b72006-06-22 16:49:14 +00001424- Bug #1510580: The 'warnings' module improperly required that a Warning
1425 category be either a types.ClassType and a subclass of Warning. The proper
1426 check is just that it is a subclass with Warning as the documentation states.
1427
Georg Brandlad29e632006-06-21 17:45:17 +00001428- The compiler module now correctly compiles the new try-except-finally
1429 statement (bug #1509132).
1430
Neal Norwitz60373cd2006-06-22 06:30:50 +00001431- The wsgiref package is now installed properly on Unix.
1432
Vinay Sajip28e57612006-07-01 10:45:20 +00001433- A bug was fixed in logging.config.fileConfig() which caused a crash on
1434 shutdown when fileConfig() was called multiple times.
1435
Gerhard Häring762fbd32006-07-02 17:48:30 +00001436- The sqlite3 module did cut off data from the SQLite database at the first
1437 null character before sending it to a custom converter. This has been fixed
1438 now.

1441-----------------
1442
Tim Peters112aad32006-07-19 00:03:19 +00001443- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1444 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1445 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001446
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001447- Assigning None to pointer type fields in ctypes structures possible
1448 overwrote the wrong fields, this is fixed now.
1449
1450- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1451 on non-Windows platforms.
1452
1453- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1454 integer or long, without range checking.
1455
1456- Patch #1517790: It is now possible to use custom objects in the ctypes
1457 foreign function argtypes sequence as long as they provide a from_param
1458 method, no longer is it required that the object is a ctypes type.
1459
1460- The '_ctypes' extension module now works when Python is configured
1461 with the --without-threads option.
1462
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001463- Bug #1513646: os.access on Windows now correctly determines write
1464 access, again.
1465
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001466- Bug #1512695: cPickle.loads could crash if it was interrupted with

1478
Tim Peters32a83612006-07-10 21:08:24 +00001479- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001480 Previously, the slight difference could cause compilation errors of the
1481 'zlib' module on systems with more than one version of zlib.
1482
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001483- The MSI compileall step was fixed to also support a TARGETDIR

Anthony Baxter51bcb682006-04-05 14:51:42 +00001511
Anthony Baxterd1136802006-06-19 12:04:15 +00001512*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +00001513
1514Core and builtins
1515-----------------
1516
Georg Brandla56b9152006-06-19 06:35:54 +00001517- Patch #1507676: Error messages returned by invalid abstract object operations
1518 (such as iterating over an integer) have been improved and now include the
1519 type of the offending object to help with debugging.
1520
Brett Cannonea3912b2006-06-13 21:46:41 +00001521- Bug #992017: A classic class that defined a __coerce__() method that returned
1522 its arguments swapped would infinitely recurse and segfault the interpreter.
1523
Neal Norwitz909eb122006-06-12 02:13:21 +00001524- Fix the socket tests so they can be run concurrently.
1525
Neal Norwitzb9845e72006-06-12 02:11:18 +00001526- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001527 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001528
Brett Cannon22565aa2006-06-09 22:31:23 +00001529- Bug #532646: object.__call__() will continue looking for the __call__
1530 attribute on objects until one without one is found. This leads to recursion
1531 when you take a class and set its __call__ attribute to an instance of the
1532 class. Originally fixed for classic classes, but this fix is for new-style.
1533 Removes the infinite_rec_3 crasher.
1534
Georg Brandl24250812006-06-09 18:45:48 +00001535- The string and unicode methods startswith() and endswith() now accept
1536 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1537
Brett Cannonde3b0522006-06-08 17:00:45 +00001538- Buffer objects, at the C level, never used the char buffer
1539 implementation even when the char buffer for the wrapped object was
1540 explicitly requested (originally returned the read or write buffer).
1541 Now a TypeError is raised if the char buffer is not present but is
1542 requested.
1543
Georg Brandlddbaa662006-06-04 21:56:52 +00001544- Patch #1346214: Statements like "if 0: suite" are now again optimized
1545 away like they were in Python 2.4.
1546
Georg Brandlb7c8f542006-05-27 12:30:25 +00001547- Builtin exceptions are now full-blown new-style classes instead of
1548 instances pretending to be classes, which speeds up exception handling
1549 by about 80% in comparison to 2.5a2.
1550
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001551- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1552 Unicode 4.1.
1553
Georg Brandlf4ef1162006-05-26 18:03:31 +00001554- Patch #921466: sys.path_importer_cache is now used to cache valid and
1555 invalid file paths for the built-in import machinery which leads to
1556 fewer open calls on startup.
1557
Tim Peters696cf432006-05-24 21:10:40 +00001558- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1559 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1560 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1561 the number of input digits (it was and remains linear-time for bases
1562 2, 4, 8, 16 and 32).
1563
Tim Petersb713ec22006-05-23 18:45:30 +00001564- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1565 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1566 an integer close to ``sys.maxint``. This was repaired by patch
1567 #1335972, which also gives a nice speedup.
1568
Richard Jonescebbefc2006-05-23 18:28:17 +00001569- Patch #1337051: reduced size of frame objects.
1570
1571- PyErr_NewException now accepts a tuple of base classes as its
1572 "base" parameter.
1573
Richard Jones7c88dcc2006-05-23 10:37:38 +00001574- Patch #876206: function call speedup by retaining allocated frame
1575 objects.
1576
Georg Brandl7b90e162006-05-18 07:01:27 +00001577- Bug #1462152: file() now checks more thoroughly for invalid mode
1578 strings and removes a possible "U" before passing the mode to the
1579 C library function.
1580
Neal Norwitz1004a532006-05-15 07:17:23 +00001581- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1582
Neal Norwitz373f0a72006-05-15 07:04:36 +00001583- Bug #1487966: Fix SystemError with conditional expression in assignment
1584
Martin v. Löwis879768d2006-05-11 13:28:43 +00001585- WindowsError now has two error code attributes: errno, which carries
1586 the error values from errno.h, and winerror, which carries the error
1587 values from winerror.h. Previous versions put the winerror.h values
1588 (from GetLastError()) into the errno attribute.
1589
Martin v. Löwis77736712006-05-04 05:51:03 +00001590- Patch #1475845: Raise IndentationError for unexpected indent.
1591
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001592- Patch #1479181: split open() and file() from being aliases for each other.
1593
Tim Peters44bd9862006-06-01 13:49:23 +00001594- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1595 methods were always silently ignored by dictionaries when comparing keys.
1596 They are now passed through (except when using the C API function
1597 ``PyDict_GetItem()``, whose semantics did not change).
1598
1599- Bug #1456209: In some obscure cases it was possible for a class with a
1600 custom ``__eq__()`` method to confuse dict internals when class instances
1601 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1602 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001604Extension Modules
1605-----------------
1606
Trent Mick960a3f82006-06-28 20:30:41 +00001607- Bug #1295808: expat symbols should be namespaced in pyexpat
1608
1609- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1610
Brett Cannon6ee7d012006-06-08 16:23:04 +00001611- Change binascii.hexlify to accept a read-only buffer instead of only a char
1612 buffer and actually follow its documentation.
1613
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001614- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1615
Nick Coghlanc649ec52006-05-29 12:43:05 +00001616- Patch #1478788 (modified version): The functional extension module has
1617 been renamed to _functools and a functools Python wrapper module added.
1618 This provides a home for additional function related utilities that are
1619 not specifically about functional programming. See PEP 309.
1620
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001621- Patch #1493701: performance enhancements for struct module.
1622
Georg Brandl378d5922006-05-17 14:26:50 +00001623- Patch #1490224: time.altzone is now set correctly on Cygwin.
1624
Georg Brandl8d3342b2006-05-16 07:38:27 +00001625- Patch #1435422: zlib's compress and decompress objects now have a
1626 copy() method.
1627
Andrew MacIntyre92913322006-06-13 15:04:24 +00001628- Patch #1454481: thread stack size is now tunable at runtime for thread
1629 enabled builds on Windows and systems with Posix threads support.
1630
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001631- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1632 (up to the system limit of 32K characters).
1633
1634- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1635 As a result, these functions now raise WindowsError instead of OSError.
1636
Tim Peters7a822da2006-05-25 21:50:17 +00001637- ``time.clock()`` on Win64 should use the high-performance Windows
1638 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1639 Windows platforms).
1640
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001641- Calling Tk_Init twice is refused if the first call failed as that
1642 may deadlock.
1643
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001644- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1645 accept it without potentially using an uninitialized pointer.
1646
1647- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1648 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1649 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001650
Gregory P. Smith372b5832006-06-05 18:48:21 +00001651- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001652 [pybsddb project SF patch number 1466734]
1653
Gregory P. Smith372b5832006-06-05 18:48:21 +00001654- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1655 parameter is supplied. [SF pybsddb bug #1477863]
1656
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001657- bsddb: the __len__ method of a DB object has been fixed to return correct
1658 results. It could previously incorrectly return 0 in some cases.
1659 Fixes SF bug 1493322 (pybsddb bug 1184012).
1660
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001661- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1662 aborts the db transaction safely when a modifier callback fails.
1663 Fixes SF python patch/bug #1408584.
1664
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001665- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001666 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001667 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1668 database calls that would previously deadlock. [SF python bug #775414]
1669
Vinay Sajip28e57612006-07-01 10:45:20 +00001670- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001671
Walter Dörwald4994d952006-06-19 08:07:50 +00001672- Patch #1506645: add Python wrappers for the curses functions
1673 is_term_resized, resize_term and resizeterm.
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001674

1676-------
1677
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001678- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1679 functions.
1680
Martin v. Löwis3798da02006-06-17 18:44:27 +00001681- Patch #812986: Update turtle output even if not tracing.
1682
Vinay Sajip28e57612006-07-01 10:45:20 +00001683- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001684 Tkinter.BaseWidget.
1685
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001686- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1687
Martin v. Löwis337487e2006-06-17 09:15:14 +00001688- Patch #763580: Add name and value arguments to Tkinter variable
1689 classes.
1690
Georg Brandl83cc0d02006-06-14 08:50:03 +00001691- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1692 mime.types file for determining MIME types.
1693
Georg Brandl2605ca82006-06-14 06:08:31 +00001694- Bug #1339007: Shelf objects now don't raise an exception in their
1695 __del__ method when initialization failed.
1696
Martin v. Löwisd8251432006-06-14 05:21:04 +00001697- Patch #1455898: The MBCS codec now supports the incremental mode for
1698 double-byte encodings.
1699
Tim Peters43898b42006-06-14 04:09:25 +00001700- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1701 guarantee that adjacent triples in the return list always describe
1702 non-adjacent blocks. Previously, a pair of matching blocks could end
1703 up being described by multiple adjacent triples that formed a partition
1704 of the matching pair.
1705
Greg Ward0e0c9f42006-06-11 16:24:11 +00001706- Bug #1498146: fix optparse to handle Unicode strings in option help,
1707 description, and epilog.
1708
Greg Wardd1c797e2006-06-11 14:42:41 +00001709- Bug #1366250: minor optparse documentation error.
1710
Greg Ward7f547402006-06-11 00:40:49 +00001711- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1712 clarify docs.
1713
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001714- The wsgiref package has been added to the standard library.
1715
Nick Coghlan676725d2006-06-08 13:54:49 +00001716- The functions update_wrapper() and wraps() have been added to the functools
1717 module. These make it easier to copy relevant metadata from the original
1718 function when writing wrapper functions.
1719
Tim Petersd6a9eef2006-06-05 01:48:21 +00001720- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1721 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001722
Martin v. Löwis3f767792006-06-04 19:36:28 +00001723- Patch #1359618: Speed up charmap encoder by using a trie structure
1724 for lookup.
1725
Tim Petersd609b1a2006-06-02 23:22:51 +00001726- The functions in the ``pprint`` module now sort dictionaries by key
1727 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1728 if and only if its display required more than one line, although that
1729 wasn't documented. The new behavior increases predictability; e.g.,
1730 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1731
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001732- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1733 (thanks for J. J. Lee).
1734
Georg Brandl2b330372006-05-28 20:23:12 +00001735- Patch #1496206: improve urllib2 handling of passwords with respect to
1736 default HTTP and HTTPS ports.
1737
George Yoshidaf3c65de2006-05-28 16:39:09 +00001738- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1739
Bob Ippolito7298f272006-05-23 18:43:47 +00001740- Patch #1281707: speed up gzip.readline.
1741
Georg Brandlb89316f2006-05-17 15:51:16 +00001742- Patch #1180296: Two new functions were added to the locale module:
1743 format_string() to get the effect of "format % items" but locale-aware,
1744 and currency() to format a monetary number with currency sign.
1745
Georg Brandle3a25832006-05-17 14:56:04 +00001746- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1747 and several features added, such as speed and geometry control.
1748
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001749- Patch #1488881: add support for external file objects in bz2 compressed
1750 tarfiles.
1751
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001752- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1753 stdout arguments, making it possible to redirect input and output
1754 for remote debugging.
1755
1756- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1757 a couple of issues, notably handling of long file names using the
1758 GNU LONGNAME extension.
1759
1760- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1761 new flag when ``name`` is already the name of an option flag.
1762
1763- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1764 package.
1765
1766- Patch #1472854: make the rlcompleter.Completer class usable on non-
1767 UNIX platforms.
1768
1769- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1770

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001802What's New in Python 2.5 alpha 2?
1803=================================
1804
1805*Release date: 27-APR-2006*
1806
1807Core and builtins
1808-----------------
1809
Thomas Heller1b046642006-04-18 18:51:06 +00001810- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1811 by converting these apis from macros into exported functions again:
1812
1813 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1814 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1815 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1816 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1817 PyRun_String Py_CompileString
1818
Martin v. Löwis45294a92006-04-18 06:24:08 +00001819- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1820
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001821- All uses of PyStructSequence_InitType have been changed to initialize
1822 the type objects only once, even if the interpreter is initialized
1823 multiple times.
1824
Neal Norwitz61546162006-04-14 05:20:28 +00001825- Bug #1454485, array.array('u') could crash the interpreter. This was
1826 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1827 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1828
1829- Py_UNICODE is unsigned. It was always documented as unsigned, but
1830 due to a bug had a signed value in previous versions.
1831
Tim Peters3a5e8b12006-04-11 01:44:07 +00001832- Patch #837242: ``id()`` of any Python object always gives a positive
1833 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1834 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001835 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001836 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001837
Tim Peters3a5e8b12006-04-11 01:44:07 +00001838 def __hash__(self):
1839 return id(self) # WRONG
1840
1841 because a hash result must be a (short) Python int but it was always
1842 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001843 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001844 was always usable as a hash value before this patch. That's no longer
1845 necessarily so.
1846
1847- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001848 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001849 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001850 #1454844)
1851
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001852- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1853 involving generators that have paused outside of any ``try`` or ``with``
1854 blocks. (In 2.5a1, a paused generator that was part of a reference
1855 cycle could not be garbage collected, regardless of whether it was
1856 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001857
Anthony Baxter51bcb682006-04-05 14:51:42 +00001858Extension Modules

1860
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001861- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1862 is a macro.
1863
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001864- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1865 fails with an error condition.
1866
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001867- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1868
1869- Bug #1117761: bsddb.*open() no longer raises an exception when using
1870 the cachesize parameter.
1871
1872- Bug #1149413: bsddb.*open() no longer raises an exception when using
1873 a temporary db (file=None) with the 'n' flag to truncate on open.
1874
1875- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1876 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001877
Armin Rigoa9017c32006-04-19 11:50:27 +00001878- Patch #1062014: AF_UNIX sockets under Linux have a special
1879 abstract namespace that is now fully supported.
1880
Anthony Baxter51bcb682006-04-05 14:51:42 +00001881Library
1882-------
1883
Peter Astrand7d1d4362006-07-14 14:04:45 +00001884- Bug #1223937: subprocess.CalledProcessError reports the exit status
1885 of the process using the returncode attribute, instead of
1886 abusing errno.
1887
Tim Peters711bf302006-04-25 03:31:36 +00001888- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1889 a doctest to be skipped (the code is not run, and the expected output
1890 or exception is ignored).
1891
Nick Coghlanda2268f2006-04-24 04:37:15 +00001892- Fixed contextlib.nested to cope with exceptions being raised and
1893 caught inside exit handlers.
1894
Greg Wardab05edc2006-04-23 03:47:58 +00001895- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1896 hex, octal, or binary; add ``append_const`` action; keep going if
1897 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1898 added ``epilog`` for better help generation).
1899
Tim Peters21fbd572006-04-21 21:18:10 +00001900- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1901 called from a thread spawned as a side effect of importing a module.
1902
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001903- The pydoc module now supports documenting packages contained in
1904 .zip or .egg files.
1905
1906- The pkgutil module now has several new utility functions, such
1907 as ``walk_packages()`` to support working with packages that are either
1908 in the filesystem or zip files.
1909
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001910- The mailbox module can now modify and delete messages from
1911 mailboxes, in addition to simply reading them. Thanks to Gregory
1912 K. Johnson for writing the code, and to the 2005 Google Summer of
1913 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001914
Tim Petersc7605f22006-04-17 21:12:33 +00001915- The ``__del__`` method of class ``local`` in module ``_threading_local``
1916 returned before accomplishing any of its intended cleanup.
1917
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001918- Patch #790710: Add breakpoint command lists in pdb.
1919
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001920- Patch #1063914: Add Tkinter.Misc.clipboard_get().
1921
Martin v. Löwis4b501e62006-04-15 08:41:11 +00001922- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1923
Anthony Baxtere29002c2006-04-12 12:07:31 +00001924- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1925 Windows. Bug #1469163.
1926
Phillip J. Eby47032112006-04-11 01:07:43 +00001927- The warnings, linecache, inspect, traceback, site, and doctest modules
1928 were updated to work correctly with modules imported from zipfiles or
1929 via other PEP 302 __loader__ objects.
1930
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001931- Patch #1467770: Reduce usage of subprocess._active to processes which
1932 the application hasn't waited on.
1933
Martin v. Löwisb04dee92006-04-10 08:34:21 +00001934- Patch #1462222: Fix Tix.Grid.
1935
Neal Norwitza31bf182006-04-09 03:35:43 +00001936- Fix exception when doing glob.glob('anything*/')
1937
Skip Montanaro262fb922006-04-21 02:31:07 +00001938- The pstats.Stats class accepts an optional stream keyword argument to
1939 direct output to an alternate file-like object.
1940
Anthony Baxter51bcb682006-04-05 14:51:42 +00001941Build
1942-----
1943
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001944- The Makefile now has a reindent target, which runs reindent.py on
1945 the library.
1946
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001947- Patch #1470875: Building Python with MS Free Compiler
1948
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001949- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001950
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001951- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1952 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001953 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001954 CXX from --with-cxx-main, see description in README.
1955
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001956- Patch #1429775: Link extension modules with the shared libpython.
1957
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001958- Fixed a libffi build problem on MIPS systems.
1959
Tim Peters8931ff12006-05-13 23:28:20 +00001960- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1961 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1962 and "%zu" for unsigned integers of type ``size_t``.
1963
Anthony Baxter51bcb682006-04-05 14:51:42 +00001964Tests
1965-----
1966
Nick Coghlanda2268f2006-04-24 04:37:15 +00001967- test_contextlib now checks contextlib.nested can cope with exceptions
1968 being raised and caught inside exit handlers.
1969
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001970- test_cmd_line now checks operation of the -m and -c command switches
1971
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001972- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1973 it separately and by hand. It also wasn't cleaning up its changes to
1974 the current Decimal context.
1975
Thomas Woutersabd08882006-04-26 15:53:30 +00001976- regrtest.py now has a -M option to run tests that test the new limits of
1977 containers, on 64-bit architectures. Running these tests is only sensible
1978 on 64-bit machines with more than two gigabytes of memory. The argument
1979 passed is the maximum amount of memory for the tests to use.
1980
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001981Tools

1984- Added the Python benchmark suite pybench to the Tools/ directory;
1985 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001987Documentation
1988-------------
1989
Tim Petersb06d28c2006-05-12 01:57:59 +00001990- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1991
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001992- PEP 343: Added Context Types section to the library reference
1993 and attempted to bring other PEP 343 related documentation into
1994 line with the implementation and/or python-dev discussions.
1995
Tim Peters8dc73d22006-04-24 02:03:16 +00001996- Bug #1337990: clarified that ``doctest`` does not support examples
1997 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002000What's New in Python 2.5 alpha 1?
2001=================================
2002
Anthony Baxterebed3f62006-04-03 15:03:44 +00002003*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002004
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002005Core and builtins
2006-----------------
2007
Nick Coghlan43832302006-04-23 17:04:07 +00002008- PEP 338: -m command line switch now delegates to runpy.run_module
2009 allowing it to support modules in packages and zipfiles
2010
Martin v. Löwisc661b882006-04-20 04:54:23 +00002011- On Windows, .DLL is not an accepted file name extension for
2012 extension modules anymore; extensions are only found if they
2013 end in .PYD.
2014
Martin v. Löwisea62d252006-04-03 10:56:49 +00002015- Bug #1421664: sys.stderr.encoding is now set to the same value as
2016 sys.stdout.encoding.
2017
Neal Norwitz92e212f2006-04-03 04:48:37 +00002018- __import__ accepts keyword arguments.
2019
Georg Brandlccadf842006-03-31 18:54:53 +00002020- Patch #1460496: round() now accepts keyword arguments.
2021
Anthony Baxter262c00a2006-03-30 10:53:17 +00002022- Fixed bug #1459029 - unicode reprs were double-escaped.
2023
Hye-Shik Changd478f342006-03-23 12:32:36 +00002024- Patch #1396919: The system scope threads are reenabled on FreeBSD
2025 5.4 and later versions.
2026
Neal Norwitze98ccf62006-03-23 05:39:47 +00002027- Bug #1115379: Compiling a Unicode string with an encoding declaration
2028 now gives a SyntaxError.
2029
Georg Brandlabd1ff82006-03-18 07:59:59 +00002030- Previously, Python code had no easy way to access the contents of a
2031 cell object. Now, a ``cell_contents`` attribute has been added
2032 (closes patch #1170323).
2033
Tim Peterscf79aac2006-03-16 01:14:46 +00002034- Patch #1123430: Python's small-object allocator now returns an arena to
2035 the system ``free()`` when all memory within an arena becomes unused
2036 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2037 freed. Some applications will see a drop in virtual memory size now,
2038 especially long-running applications that, from time to time, temporarily
2039 use a large number of small objects. Note that when Python returns an
2040 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002041 platform C library will in turn return that memory to the operating system.
2042 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002043 appears to be effective at least on Microsoft C and gcc-based systems.
2044 Thanks to Evan Jones for hard work and patience.
2045
Georg Brandl533ff6f2006-03-08 18:09:27 +00002046- Patch #1434038: property() now uses the getter's docstring if there is
2047 no "doc" argument given. This makes it possible to legitimately use
2048 property() as a decorator to produce a read-only property.
2049
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002050- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2051 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2052 of requiring an int or long in slicing and a few other contexts, enabling
2053 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2054
Neal Norwitz995acdf2006-03-07 05:01:00 +00002055- Fixed various bugs reported by Coverity's Prevent tool.
2056
Brett Cannonbf364092006-03-01 04:25:17 +00002057- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2058 new exception base class, BaseException, which has a new message attribute.
2059 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2060 Raising a string exception now raises a DeprecationWarning.
2061
Thomas Woutersfb609f42006-02-28 16:37:25 +00002062- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2063 explicitly relative, using 'from .module import name' to mean 'from the same
2064 package as this module is in. Imports without dots still default to the
2065 old relative-then-absolute, unless 'from __future__ import
2066 absolute_import' is used.
2067
Brett Cannona7446e32006-02-27 23:39:10 +00002068- Properly check if 'warnings' raises an exception (usually when a filter set
2069 to "error" is triggered) when raising a warning for raising string
2070 exceptions.
2071
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002072- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002073 The name was removed from Include/code.h.
2074
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002075- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002076
Guido van Rossum1968ad32006-02-25 22:38:04 +00002077- Patch 1433928:
2078 - The copy module now "copies" function objects (as atomic objects).
2079 - dict.__getitem__ now looks for a __missing__ hook before raising
2080 KeyError.
2081
Tim Peters84ef21c2006-02-28 20:39:06 +00002082- PEP 343: with statement implemented. Needs ``from __future__ import
2083 with_statement``. Use of 'with' as a variable will generate a warning.
2084 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002085 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002086 The following objects have __context__ methods:
2087 - The built-in file type.
2088 - The thread.LockType type.
2089 - The following types defined by the threading module:
2090 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2091 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002092
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002093- Fix the encodings package codec search function to only search
2094 inside its own package. Fixes problem reported in patch #1433198.
2095
2096 Note: Codec packages should implement and register their own
2097 codec search function. PEP 100 has the details.
2098
Tim Peters9ea89d22006-06-04 03:26:02 +00002099- PEP 353: Using ``Py_ssize_t`` as the index type.
2100
2101- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2102 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2103 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2104 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2105 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002106
Neal Norwitzfc76d632006-01-10 06:03:13 +00002107- Patch #1400181, fix unicode string formatting to not use the locale.
2108 This is how string objects work. u'%f' could use , instead of .
2109 for the decimal point. Now both strings and unicode always use periods.
2110
Neal Norwitz671b9e32006-01-09 07:07:12 +00002111- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2112 configure would break checking curses.h.
2113
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002114- Bug #959576: The pwd module is now builtin. This allows Python to be
2115 built on UNIX platforms without $HOME set.
2116
Neal Norwitzc10978f2005-12-19 06:07:16 +00002117- Bug #1072182, fix some potential problems if characters are signed.
2118
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002119- Bug #889500, fix line number on SyntaxWarning for global declarations.
2120
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002121- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2122
Neal Norwitze7214a12005-12-18 05:03:17 +00002123- Support for converting hex strings to floats no longer works.
2124 This was not portable. float('0x3') now raises a ValueError.
2125
Barry Warsaw2a38a862005-12-18 01:27:35 +00002126- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002127 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002128 is now displayed in interactive prompt banner.
2129
Georg Brandlfa166682005-12-17 21:45:17 +00002130- Implementation of PEP 341 - Unification of try/except and try/finally.
2131 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002132 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002133
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002134- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2135 now encodes backslash correctly.
2136
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002137- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2138
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002139- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002140 and long longs.
2141
Neal Norwitz67715f02005-11-09 06:59:35 +00002142- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002143 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002144 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002145
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002146- Replaced most Unicode charmap codecs with new ones using the
2147 new Unicode translate string feature in the builtin charmap
2148 codec; the codecs were created from the mapping tables available
2149 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2150 encodings now include a mapping for the Apple logo)
2151
Tim Peterse3547fd2005-12-16 23:13:57 +00002152- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002153
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002154- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002155
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002156- A new AST parser implementation was completed. The abstract
2157 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002158 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002159
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002160- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002161 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2162
Neal Norwitz708e51a2005-10-03 04:48:15 +00002163- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2164
Neal Norwitz11bd1192005-10-03 00:54:56 +00002165- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2166 Provide a warning when a directory is passed on the command line.
2167
Neal Norwitz40d37812005-10-02 01:48:49 +00002168- Fix segfault with invalid coding.
2169
2170- SF bug #772896: unknown encoding results in MemoryError.
2171
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002172- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002173 supported a __len__() method which evaluated to False when the iterator
2174 was empty.
2175
Guido van Rossum630db602005-09-20 18:49:54 +00002176- On 64-bit platforms, when __len__() returns a value that cannot be
2177 represented as a C int, raise OverflowError.
2178
Skip Montanarof8948ca2005-09-19 03:54:46 +00002179- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002180 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002181
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002182- SF bug #893549: parsing keyword arguments was broken with a few format
2183 codes.
2184
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002185- Changes donated by Elemental Security to make it work on AIX 5.3
2186 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2187 bug #105470: test_pwd fails on 64bit system (Opteron).
2188
Guido van Rossum539c6622005-09-14 17:49:54 +00002189- Changes donated by Elemental Security to make it work on HP-UX 11 on
2190 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2191
Georg Brandl4550b8d2005-08-26 06:43:52 +00002192- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002193 (fixes bug #1119418).
2194
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002195- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2196
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002197- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2198 exceptions that cause a function to exit.
2199
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002200- The implementation of set() and frozenset() was revised to use its
2201 own internal data structure. Memory consumption is reduced by 1/3
2202 and there are modest speed-ups as well. The API is unchanged.
2203
Tim Petersde7990b2005-07-17 23:45:23 +00002204- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2205
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002206- SF bug #1229429: PyObject_CallMethod failed to decrement some
2207 reference counts in some error exit cases.
2208
Tim Petersecc6e6a2005-07-10 22:30:55 +00002209- SF bug #1185883: Python's small-object memory allocator took over
2210 a block managed by the platform C library whenever a realloc specified
2211 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002212 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002213 portable way to copy data from the C-managed block into Python's
2214 small-object space without risking a memory fault. Python's small-object
2215 realloc now leaves such blocks under the control of the platform C
2216 realloc.
2217
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002218- SF bug #1232517: An overflow error was not detected properly when
2219 attempting to convert a large float to an int in os.utime().
2220
Raymond Hettinger3296e692005-06-29 23:29:56 +00002221- SF bug #1224347: hex longs now print with lowercase letters just
2222 like their int counterparts.
2223
Michael W. Hudson188d4362005-06-20 16:52:57 +00002224- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2225 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2226 interpreter states; back out that fix and do a better job (see
2227 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2228 for a longer write-up of the problem).
2229
Michael W. Hudsondf888462005-06-03 14:41:55 +00002230- SF patch #1180995: marshal now uses a binary format by default when
2231 serializing floats.
2232
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002233- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2234 the routines that promise to produce IEEE 754 binary representations
2235 of floats now simply copy bytes around.
2236
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002237- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2238 278.
2239
Brett Cannonc3647ac2005-04-26 03:45:26 +00002240- patch #1109424: int, long, float, complex, and unicode now check for the
2241 proper magic slot for type conversions when subclassed. Previously the
2242 magic slot was ignored during conversion. Semantics now match the way
2243 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002244 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002245 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002246 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002247
Barry Warsawc8d907c2005-04-19 23:43:40 +00002248- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2249 NULL, now raise an AttributeError when attempting to set or delete the
2250 attribute. Previously a TypeError was raised, but this was inconsistent
2251 with the equivalent pure-Python implementation.
2252
Michael W. Hudson774479c2005-04-18 08:46:17 +00002253- It is now safe to call PyGILState_Release() before
2254 PyEval_InitThreads() (note that if there is reason to believe there
2255 are multiple threads around you still must call PyEval_InitThreads()
2256 before using the Python API; this fix is for extension modules that
2257 have no way of knowing if Python is multi-threaded yet).
2258
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002259- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2260 disabled caused a crash.
2261
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002262- Bug #1165306: instancemethod_new allowed the creation of a method
2263 with im_class == im_self == NULL, which caused a crash when called.
2264
Tim Petersecc6e6a2005-07-10 22:30:55 +00002265- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002266 fixes the crash seen in bug #1165761
2267
Raymond Hettinger96229b12005-03-11 06:49:40 +00002268- Added two new builtins, any() and all().
2269
Brett Cannon409d8f22005-03-05 06:47:57 +00002270- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002271 (e.g., ``class C(): pass`` is no longer a syntax error).
2272 Patch #1176012 added support to the 'parser' module and 'compiler' package
2273 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002274
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002275- Patch #1115086: Support PY_LONGLONG in structmember.
2276
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002277- Bug #1155938: new style classes did not check that __init__() was
2278 returning None.
2279
Tim Petersecc6e6a2005-07-10 22:30:55 +00002280- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002281 ('\') with a specific error message.
2282
Martin v. Löwisff232d72005-03-03 09:24:38 +00002283- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2284
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002285- Bug #1124295: the __name__ attribute of file objects was
2286 inadvertently made inaccessible in restricted mode.
2287
Tim Petersecc6e6a2005-07-10 22:30:55 +00002288- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002289 an ferror() call.
2290
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002291- min() and max() now support key= arguments with the same meaning as in
2292 list.sort().
2293
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002294- The peephole optimizer now performs simple constant folding in expressions:
2295 (2+3) --> (5).
2296
Raymond Hettingera422c342005-01-11 03:03:27 +00002297- set and frozenset objects can now be marshalled. SF #1098985.
2298
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002299- Bug #1077106: Poor argument checking could cause memory corruption
2300 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002301
Jeremy Hyltonab630502005-02-04 18:44:06 +00002302- The parser did not complain about future statements in illegal
2303 positions. It once again reports a syntax error if a future
2304 statement occurs after anything other than a doc string.
2305
Neil Schemenauercf52c072005-08-12 17:34:58 +00002306- Change the %s format specifier for str objects so that it returns a
2307 unicode instance if the argument is not an instance of basestring and
2308 calling __str__ on the argument returns a unicode instance.
2309
Tim Petersf4e69282006-02-27 17:15:31 +00002310- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2311 current thread state when the auto-GIL-state machinery knows about
2312 it (since the thread state is being deleted, continuing to remember it
2313 can't help, but can hurt if another thread happens to get created with
2314 the same thread id).
2315
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002316Extension Modules
2317-----------------
2318
Georg Brandl43f08a82006-03-31 18:01:16 +00002319- Patch #1380952: fix SSL objects timing out on consecutive read()s
2320
Neal Norwitz05a45592006-03-20 06:30:08 +00002321- Patch #1309579: wait3 and wait4 were added to the posix module.
2322
Anthony Baxterfa869072006-03-20 05:21:58 +00002323- Patch #1231053: The audioop module now supports encoding/decoding of alaw.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002506- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2507 been renamed to have only a single underscore prefix. This was done to
2508 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002509
Nick Coghlan43832302006-04-23 17:04:07 +00002510- PEP 338: new module runpy defines a run_module function to support
2511 executing modules which provide access to source code or a code object
2512 via the PEP 302 import mechanisms.
2513
Anthony Baxter93f5b932006-04-03 08:05:07 +00002514- The email module's parsedate_tz function now sets the daylight savings

2522 in attribute values.
2523
Anthony Baxterc51ee692006-04-01 00:57:31 +00002524- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002525 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002526 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002527 module will not be built.
2528
Tim Petersc17976e2006-04-01 00:26:53 +00002529- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2530 aren't officially supported here, and trying to use them will probably
2531 raise an exception some day. But dicts have been allowed, and "mostly
2532 worked", so support for them won't go away without warning.
2533
Georg Brandl338ef7d2006-03-31 18:42:16 +00002534- Bug #1445068: getpass.getpass() can now be given an explicit stream
2535 argument to specify where to write the prompt.
2536

2552
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002553- email 4.0 package now integrated. This is largely the same as the email 3.0
2554 package that was included in Python 2.3, except that PEP 8 module names are
2555 now used (e.g. mail.message instead of email.Message). The MIME classes
2556 have been moved to a subpackage (e.g. email.mime.text instead of
2557 email.MIMEText). The old names are still supported for now. Several
2558 deprecated Message methods have been removed and lots of bugs have been
2559 fixed. More details can be found in the email package documentation.
2560
Walter Dörwald40108c92006-03-27 08:15:44 +00002561- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2562 (a subclass of tuple) that provides incremental decoders and encoders
2563 (a way to use stateful codecs without the stream API). Python functions
2564 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2565 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2566 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00002568- Patch #1359365: Calling next() on a closed StringIO.String object raises
2569 a ValueError instead of a StopIteration now (like file and cString.String do).
2570 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2571 called before (like file and StringIO.StringIO do).

2647 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2648 Ronald L. Rivest offered this advice for Python:
2649
2650 "The consensus of researchers in this area (at least as
2651 expressed at the NIST Hash Function Workshop 10/31/05),
2652 is that SHA-256 is a good choice for the time being, but
2653 that research should continue, and other alternatives may
2654 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002655

2836 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002837 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002838 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002839 + Dialect parameter parsing has been re-implemented to improve error

2841 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2842 dictates.
2843 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002844 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002845 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002846 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2847 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002848 + reader now allows \r characters to be quoted (previously it only allowed
2849 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002850 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002851 + Dialect classes passed to the module are no longer instantiated by
2852 the module before being parsed (the former validation scheme required
2853 this, but the mechanism was unreliable).
2854 + The dialect registry now contains instances of the internal
2855 C-coded dialect type, rather than references to python objects.
2856 + the internal c-coded dialect type is now immutable.
2857 + register_dialect now accepts the same keyword dialect specifications
2858 as the reader and writer, allowing the user to register dialects
2859 without first creating a dialect class.
2860 + a configurable limit to the size of parsed fields has been added -
2861 previously, an unmatched quote character could result in the entire
2862 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002863 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002864 the parser field size limit (returning the former limit). The initial
2865 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002866 + A line_num attribute has been added to the reader object, which tracks
2867 the number of lines read from the source iterator. This is not
2868 the same as the number of records returned, as records can span
2869 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002870 + reader and writer objects were not being registered with the cyclic-GC.
2871 This has been fixed.
2872
Brett Cannone6539c42005-01-08 02:43:53 +00002873- _DummyThread objects in the threading module now delete self.__block that is
2874 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2875 lock primitives tend to be limited in number and thus should not be wasted on
2876 a _DummyThread object. Fixes bug #1089632.
2877
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002878- The imghdr module now detects Exif files.
2879
Raymond Hettinger6065d322004-12-20 23:51:53 +00002880- StringIO.truncate() now correctly adjusts the size attribute.
2881 (Bug #951915).
2882
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002883- locale.py now uses an updated locale alias table (built using
2884 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2885 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002886 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002887
Raymond Hettinger3557f422004-12-07 12:02:02 +00002888- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2889
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002890- the pickle module no longer accepts the deprecated None option in the
2891 args tuple returned by __reduce__().
2892
Brett Cannon84667c02004-12-07 03:25:18 +00002893- optparse now optionally imports gettext. This allows its use in setup.py.
2894
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002895- the pickle module no longer uses the deprecated bin parameter.
2896
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002897- the shelve module no longer uses the deprecated binary parameter.
2898
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002899- the pstats module no longer uses the deprecated ignore() method.
2900
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002901- the filecmp module no longer uses the deprecated use_statcache argument.
2902
Raymond Hettinger664347b2004-12-04 21:21:53 +00002903- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2904 extended or overridden by subclasses. Formerly, the subclassed method would
2905 be ignored by the rest of the module. (Bug #1078905).
2906
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002907- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002908 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002909
Walter Dörwald36733692004-12-22 12:50:50 +00002910- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2911 once when a size argument is given. This prevents a buffer overflow in the
2912 tokenizer with very long source lines.
2913
Barry Warsaw538561e2006-01-01 21:48:54 +00002914- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2915 immediately after creating the object, without any intervening
2916 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002917
Skip Montanaro05885812005-01-16 20:48:27 +00002918- The reconvert.quote function can now emit triple-quoted strings. The
2919 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002920
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002921- ``UserString.MutableString`` now supports negative indices in
2922 ``__setitem__`` and ``__delitem__``
2923
Greg Ward40407942005-03-05 02:53:17 +00002924- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2925 correctly.
2926
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002927- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2928 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2929 character even if the user has passed a size parameter to get a proper
2930 line ending. Remove the special handling of a "\r\n" that has been split
2931 between two lines.
2932
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002933- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2934 about illegal code points. The codec now supports PEP 293 style error
2935 handlers.
2936
Walter Dörwald78a78b02005-09-01 12:04:29 +00002937- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002938 from the input stream, so that the output is a byte string in the correct
2939 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002940
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002941- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2942 considering it exactly like a '*'.
2943
Walter Dörwald007f8df2005-10-09 19:42:27 +00002944- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2945 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002946
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002947- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2948
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002949- Patch #1413711: Certain patterns of differences were making difflib
2950 touch the recursion limit.
2951
Walter Dörwald58917a62006-03-31 15:26:22 +00002952- Bug #947906: An object oriented interface has been added to the calendar
2953 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002954 called as a script (e.g. via ``python -mcalendar``). Localized month and
2955 weekday names can be ouput (even if an exotic encoding is used) using
2956 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002957
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002958Build
2959-----
2960
Neal Norwitz602d3392006-03-31 08:21:40 +00002961- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2962 by using -mieee gcc option.
2963
Martin v. Löwis86d66262006-02-17 08:40:11 +00002964- Patch #1432345: Make python compile on DragonFly.
2965
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002966- Build support for Win64-AMD64 was added.
2967
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002968- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2969
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002970- Patch #881820: look for openpty and forkpty also in libbsd.
2971
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002972- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2973 The zlib module is now builtin on Windows.
2974
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002975- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2976
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002977- Bug #1189330: configure did not correctly determine the necessary
2978 value of LINKCC if python was built with GCC 4.0.
2979
Trent Mick8321b422005-07-26 02:29:21 +00002980- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2981 vulnerability in zlib 1.2.1 and 1.2.2.
2982
Brett Cannon08cd5982005-04-24 22:26:38 +00002983- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2984 flags that change binary compatibility. Changes were also made to
2985 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002986 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002987
Bob Ippolitoed233462005-03-29 13:47:59 +00002988- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2989 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2990 no longer exists). This configure patch makes things right.
2991
Martin v. Löwise2713be2005-03-08 15:03:08 +00002992- Bug #1158607: Build with --disable-unicode again.
2993
Brett Cannon46d96232005-02-16 00:07:19 +00002994- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2995 defined. Discovered as a result of not being able to build on OS X.
2996
Brett Cannon516592f2004-12-07 00:42:59 +00002997- setup.py now uses the directories specified in LDFLAGS using the -L option
2998 and in CPPFLAGS using the -I option for adding library and include
2999 directories, respectively, for compiling extension modules against. This has
3000 led to the core being compiled using the values in CPPFLAGS. It also removes
3001 the need for the special-casing of both DarwinPorts and Fink for darwin since
3002 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3003 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3004 Fink, ``-I/opt/local/include`` for DarwinPorts).
3005
Brett Cannon43802422005-02-10 20:48:03 +00003006- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3007 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3008 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3009 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003011C API
3012-----
3013
Tim Petersc9d78aa2006-03-26 23:27:58 +00003014- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3015 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3016 is obtained via the ``PyObject_`` family, it must be released via the
3017 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3018 always been officially true, but when Python's small-object allocator was
3019 introduced, an attempt was made to cater to a few extension modules
3020 discovered at the time that obtained memory via ``PyObject_New`` but
3021 released it via ``PyMem_DEL``. It's years later, and if such code still
3022 exists it will fail now (probably with segfaults, but calling wrong
3023 low-level memory management functions can yield many symptoms).
3024
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003025- Added a C API for set and frozenset objects.
3026
Raymond Hettinger66517482004-12-03 11:45:13 +00003027- Removed PyRange_New().
3028
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003029- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3030 mapping argument now. This string is used as a mapping table. Byte values
3031 greater than the length of the string and 0xFFFE are treated as undefined
3032 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003039
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00003040- Patch #1276356: New resource "urlfetch" is implemented. This enables
