Georg Brandld59ea472007-03-08 18:37:35 +0000587- unittest now verifies more of its assumptions. In particular, TestCase
588 and TestSuite subclasses (not instances) are no longer accepted in
589 TestSuite.addTest(). This should cause no incompatibility since it
590 never made sense with ordinary subclasses -- the failure just occurred
591 later, with a more cumbersome exception.

Neal Norwitzff4b63b2006-08-04 04:50:21 +0000945
946Core and builtins
947-----------------
948
Neal Norwitz24b6f202006-09-05 04:43:56 +0000949- Fix infinite recursion when subclassing long and overriding __hash__.
950
951- Fix concatenation (+=) of long strings.
952
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000953- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +0000954 compared equal or unequal to a string and a UnicodeDecodeError
955 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +0000956
Marc-André Lemburg040f76b2006-08-14 10:55:19 +0000957 Instead, the equal (==) and unequal (!=) comparison operators will
958 now issue a UnicodeWarning and interpret the two objects as
959 unequal. The UnicodeWarning can be filtered as desired using
960 the warning framework, e.g. silenced completely, turned into an
961 exception, logged, etc.
962
963 Note that compare operators other than equal and unequal will still
964 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +0000965
Marc-André Lemburg757ea272006-08-14 11:44:34 +0000966- Fix segfault when doing string formatting on subclasses of long.
967
968- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
969 with new-style classes.
970
971- Fix bug related to __len__ functions returning negative values with
972 classic classes.
973
974- Patch #1538606, Fix __index__() clipping. There were some problems
975 discovered with the API and how integers that didn't fit into Py_ssize_t
976 were handled. This patch attempts to provide enough alternatives
977 to effectively use __index__.
978
Martin v. Löwisab2f8f72006-08-09 07:57:39 +0000979- Bug #1536021: __hash__ may now return long int; the final hash
980 value is obtained by invoking hash on the long int.
981
Thomas Hellerab1049c2006-08-08 17:37:00 +0000982- Bug #1536786: buffer comparison could emit a RuntimeWarning.
983
Georg Brandl7e3ba2a2006-08-06 08:23:54 +0000984- Bug #1535165: fixed a segfault in input() and raw_input() when
985 sys.stdin is closed.
986
Thomas Heller74d36f02006-08-04 18:17:40 +0000987- On Windows, the PyErr_Warn function is now exported from
988 the Python dll again.
989
Neal Norwitz4ffedad2006-08-04 04:58:47 +0000990- Bug #1191458: tracing over for loops now produces a line event
991 on each iteration. Fixing this problem required changing the .pyc
992 magic number. This means that .pyc files generated before 2.5c1
993 will be regenerated.
994
Neal Norwitz0cbd8052006-08-04 05:09:28 +0000995- Bug #1333982: string/number constants were inappropriately stored
996 in the byte code and co_consts even if they were not used, ie
997 immediately popped off the stack.
998
Georg Brandle9462c72006-08-04 18:03:37 +0000999- Fixed a reference-counting problem in property().

1002Library
1003-------
1004
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001005- Fix a bug in the ``compiler`` package that caused invalid code to be
1006 generated for generator expressions.
1007
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001008- The distutils version has been changed to 2.5.0. The change to
1009 keep it programmatically in sync with the Python version running
1010 the code (introduced in 2.5b3) has been reverted. It will continue
1011 to be maintained manually as static string literal.
1012
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001013- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001014 and this cannot be converted to the required C type, an exception is
1015 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001016 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001017
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001018- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001019 an exception.
1020
Tim Peterscbdd3502006-09-05 01:47:53 +00001021- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001022 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001023 workarounds for clocks with low resolution, to stop the code yielding
1024 duplicate UUIDs.
1025
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001026- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1027 before raising SystemExit, allowing IDLE to honor quit() and exit().
1028
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001029- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1030
Georg Brandl7a1af772006-08-14 21:55:28 +00001031- Patch #1536071: trace.py should now find the full module name of a
1032 file correctly even on Windows.
1033
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001034- logging's atexit hook now runs even if the rest of the module has
1035 already been cleaned up.
1036
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001037- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001038
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001039- Bug #1531405, format_exception no longer raises an exception if
1040 str(exception) raised an exception.
1041
Neil Schemenauer06ded092006-08-04 16:20:30 +00001042- Fix a bug in the ``compiler`` package that caused invalid code to be
1043 generated for nested functions.

1054 raises the correct exceptions.
1055
Thomas Heller1ce433e2006-08-14 16:20:04 +00001056- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1057 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1058
Thomas Heller86720042006-08-14 11:17:48 +00001059- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1060 uses the _as_parameter_ attribute when objects are passed to foreign
1061 function calls. The ctypes version number was changed to 1.0.1.
1062
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001063- Bug #1530559, struct.pack raises TypeError where it used to convert.
1064 Passing float arguments to struct.pack when integers are expected
1065 now triggers a DeprecationWarning.

1115Core and builtins
1116-----------------
1117
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001118- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001119 returned a long (see PEP 353).
1120
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001121- Bug #1515471: string.replace() accepts character buffers again.
1122
Neal Norwitz07aadb12006-07-30 06:55:48 +00001123- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1124 This provides the proper warning for struct.pack().
1125 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1126
Neal Norwitz0d62a062006-07-30 06:53:31 +00001127- Patch #1531113: Fix augmented assignment with yield expressions.
1128 Also fix a SystemError when trying to assign to yield expressions.
1129
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001130- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1131 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1132 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1133 excessive filesystem operations during imports.
1134
Tim Petersbc24eee2006-07-27 01:14:53 +00001135- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1136 operations on signed longs that are formally undefined by C.
1137 Unfortunately, at least one compiler now cares about that, so complicated
1138 the code to make that compiler happy again.
1139
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001140- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1141
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001142- Patch #1232023: Stop including current directory in search
1143 path on Windows.
1144
Neal Norwitze1fdb322006-07-21 05:32:28 +00001145- Fix some potential crashes found with failmalloc.
1146
Neal Norwitze7563102006-07-17 01:00:16 +00001147- Fix warnings reported by Klocwork's static analysis tool.
1148
Neal Norwitz84be93b2006-07-16 01:50:38 +00001149- Bug #1512814, Fix incorrect lineno's when code within a function
1150 had more than 255 blank lines.
1151
Georg Brandl9dceedb2006-07-12 15:31:17 +00001152- Patch #1521179: Python now accepts the standard options ``--help`` and
1153 ``--version`` as well as ``/?`` on Windows.
1154
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001155- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001156 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001157 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001158
Tim Peters112aad32006-07-19 00:03:19 +00001159- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001160 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001161 new ``sys._current_frames()`` returns a dictionary with one entry,
1162 mapping the faux "thread id" 0 to the current frame.
1163
Ronald Oussoren3075e162006-07-25 20:28:55 +00001164- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001165

1169
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001170- Correction of patch #1455898: In the mbcs decoder, set final=False
1171 for stream decoder, but final=True for the decode function.
1172
Georg Brandl07fec3a2006-08-01 18:49:24 +00001173- os.urandom no longer masks unrelated exceptions like SystemExit or
1174 KeyboardInterrupt.
1175
Tim Peters4643c2f2006-08-10 22:45:34 +00001176- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001177 shutil.copytree on Windows
1178
Georg Brandle34ac7c2006-07-30 11:07:23 +00001179- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1180 refers to file descriptors, not file objects.
1181
Tim Peterscbdd3502006-09-05 01:47:53 +00001182- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001183 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001184 #1513611, and probably others.
1185
Georg Brandledd9b0d2006-07-29 09:33:26 +00001186- Bug #1441397: The compiler module now recognizes module and function
1187 docstrings correctly as it did in Python 2.4.
1188
Tim Peters6f681472006-07-27 23:44:37 +00001189- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1190 lost that tests are sorted by name before being run. This rarely
1191 matters for well-written tests, but can create baffling symptoms if
1192 side effects from one test to the next affect outcomes. ``DocTestFinder``
1193 has been changed to sort the list of tests it returns.
1194
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001195- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001196 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001197
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001198- Bug #978833: Really close underlying socket in _socketobject.close.
1199
Georg Brandldb232dc2006-08-20 13:15:43 +00001200- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1201 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001202
Georg Brandlcf0c1722006-07-26 07:23:32 +00001203- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1204 to recursive calls and call it with the failing package name.
1205
Martin v. Löwis0b483032006-07-25 09:53:12 +00001206- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1207
Georg Brandlc13c34c2006-07-24 14:09:56 +00001208- Patch #1515343: Fix printing of deprecated string exceptions with a
1209 value in the traceback module.
1210
Greg Ward48fae7a2006-07-23 16:05:51 +00001211- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1212
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001213- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1214
Brett Cannoncaebe222006-07-18 04:41:36 +00001215- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1216 argument tuple. For arguments where zero is illegal, the value is forced to
1217 the minimum value that is correct. This is to support an undocumented but
1218 common way people used to fill in inconsequential information in the time
1219 tuple pre-2.4.
1220
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001221- Patch #1220874: Update the binhex module for Mach-O.
1222
Barry Warsawb110bad2006-07-21 14:51:07 +00001223- The email package has improved RFC 2231 support, specifically for
1224 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1225 (name*0=<blah>) parameter continuations. This may change the types of
1226 values returned from email.message.Message.get_param() and friends.
1227 Specifically in some cases where non-encoded continuations were used,
1228 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1229 will just return the string (since non-encoded continuations don't have
1230 charset and language parts).
1231
1232 Also, whereas % values were decoded in all parameter continuations, they are
1233 now only decoded in encoded parameter parts.
1234
Ronald Oussoren3075e162006-07-25 20:28:55 +00001235- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1236
1237- Bug #1517996: IDLE now longer shows the default Tk menu when a
1238 path browser, class browser or debugger is the frontmost window on MacOS X
1239
Barry Warsaw00decd72006-07-27 23:43:15 +00001240- Patch #1520294: Support for getset and member descriptors in types.py,
1241 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1242 of an object against these built-in types and more importantly, for getting
1243 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001246Extension Modules
1247-----------------
1248
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001249- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1250 a socket operation on a socket with a timeout, the exception will be
1251 caught correctly. Previously, the exception was not caught.
1252
Thomas Heller1393d6a2006-07-28 21:43:20 +00001253- Patch #1529514: The _ctypes extension is now compiled on more
1254 openbsd target platforms.
1255
Tim Peters9cab5932006-07-28 00:30:00 +00001256- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1257 a memory leak, affecting pickles and deep copies.
1258
Tim Petersbc24eee2006-07-27 01:14:53 +00001259- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001260 Paul Eggert.
1261
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001262- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1263
Thomas Hellerce049a02006-07-14 17:51:14 +00001264- Patch #1521817: Index range checking on ctypes arrays containing
1265 exactly one element enabled again. This allows iterating over these
1266 arrays, without the need to check the array size before.
1267
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001268- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001269 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001270 /dev/null in certain cases; this is now fixed.
1271
Thomas Heller47d7a062006-07-12 08:43:47 +00001272- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1273 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001274
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001275- Because of a misspelled preprocessor symbol, ctypes was always
1276 compiled without thread support; this is now fixed.
1277
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001278- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1279 methods now allow their database parameter to be None as the
1280 sleepycat API allows.
1281
Matt Flemingec926502006-07-28 11:27:27 +00001282- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1283 bluetooth API compared with Linux and FreeBSD.
1284
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001285Tests
1286-----
1287
1288- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1289 how long the test file should take to play. Now accepts taking 2.93 secs
1290 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1291
Georg Brandl4793aa32006-07-28 18:31:39 +00001292- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1293 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1294 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001301Mac
1302---
1303
1304- PythonLauncher now works correctly when the path to the script contains
1305 characters that are treated specially by the shell (such as quotes).
1306
1307- Bug #1527397: PythonLauncher now launches scripts with the working directory
1308 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001309 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001310 expect.

1319-----------------
1320
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001321- Bug #1441486: The literal representation of -(sys.maxint - 1)
1322 again evaluates to a int object, not a long.
1323
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001324- Bug #1501934: The scope of global variables that are locally assigned
1325 using augmented assignment is now correctly determined.
1326
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001327- Bug #927248: Recursive method-wrapper objects can now safely
1328 be released.
1329
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001330- Bug #1417699: Reject locale-specific decimal point in float()
1331 and atof().
1332
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001333- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1334 omit a default "error" argument for NULL pointer. This allows
1335 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001336
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001337- Bug #1519018: 'as' is now validated properly in import statements.
1338
Neal Norwitz28746ab2006-07-09 22:14:42 +00001339- On 64 bit systems, int literals that use less than 64 bits are
1340 now ints rather than longs.
1341
Neal Norwitzed657552006-07-10 00:04:44 +00001342- Bug #1512814, Fix incorrect lineno's when code at module scope
1343 started after line 256.
1344
Tim Peters32a83612006-07-10 21:08:24 +00001345- New function ``sys._current_frames()`` returns a dict mapping thread
1346 id to topmost thread stack frame. This is for expert use, and is
1347 especially useful for debugging application deadlocks. The functionality
1348 was previously available in Fazal Majid's ``threadframe`` extension
1349 module, but it wasn't possible to do this in a wholly threadsafe way from
1350 an extension.

1367
Thomas Woutersadd19112006-07-05 11:03:49 +00001368- string.Template() now correctly handles tuple-values. Previously,
1369 multi-value tuples would raise an exception and single-value tuples would
1370 be treated as the value they contain, instead.
1371
Martin v. Löwisede77f52006-07-03 13:01:35 +00001372- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1379 degrees and radians.
1380
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001381- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001382 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001383

1385 is created.
1386
Martin v. Löwis7596e832006-07-01 15:33:37 +00001387- Bug #1513223: .close() of a _socketobj now releases the underlying
1388 socket again, which then gets closed as it becomes unreferenced.
1389
Fred Drake10497c82006-06-29 02:57:48 +00001390- Bug #1504333: Make sgmllib support angle brackets in quoted
1391 attribute values.

1393- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1394 sgmllib ('[' and ']' were not accepted).
1395
Georg Brandl1be63af2006-06-28 20:23:25 +00001396- Fix a bug in the turtle module's end_fill function.
1397
Brett Cannon53ab5b72006-06-22 16:49:14 +00001398- Bug #1510580: The 'warnings' module improperly required that a Warning
1399 category be either a types.ClassType and a subclass of Warning. The proper
1400 check is just that it is a subclass with Warning as the documentation states.
1401
Georg Brandlad29e632006-06-21 17:45:17 +00001402- The compiler module now correctly compiles the new try-except-finally
1403 statement (bug #1509132).
1404
Neal Norwitz60373cd2006-06-22 06:30:50 +00001405- The wsgiref package is now installed properly on Unix.
1406
Vinay Sajip28e57612006-07-01 10:45:20 +00001407- A bug was fixed in logging.config.fileConfig() which caused a crash on
1408 shutdown when fileConfig() was called multiple times.
1409
Gerhard Häring762fbd32006-07-02 17:48:30 +00001410- The sqlite3 module did cut off data from the SQLite database at the first
1411 null character before sending it to a custom converter. This has been fixed
1412 now.

1415-----------------
1416
Tim Peters112aad32006-07-19 00:03:19 +00001417- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1418 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1419 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001420
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001421- Assigning None to pointer type fields in ctypes structures possible
1422 overwrote the wrong fields, this is fixed now.
1423
1424- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1425 on non-Windows platforms.
1426
1427- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1428 integer or long, without range checking.
1429
1430- Patch #1517790: It is now possible to use custom objects in the ctypes
1431 foreign function argtypes sequence as long as they provide a from_param
1432 method, no longer is it required that the object is a ctypes type.
1433
1434- The '_ctypes' extension module now works when Python is configured
1435 with the --without-threads option.
1436
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001437- Bug #1513646: os.access on Windows now correctly determines write
1438 access, again.
1439
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001440- Bug #1512695: cPickle.loads could crash if it was interrupted with
1441 a KeyboardInterrupt.

1452
Tim Peters32a83612006-07-10 21:08:24 +00001453- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001454 Previously, the slight difference could cause compilation errors of the
1455 'zlib' module on systems with more than one version of zlib.
1456
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001457- The MSI compileall step was fixed to also support a TARGETDIR
1458 with spaces in it.

1488Core and builtins
1489-----------------
1490
Georg Brandla56b9152006-06-19 06:35:54 +00001491- Patch #1507676: Error messages returned by invalid abstract object operations
1492 (such as iterating over an integer) have been improved and now include the
1493 type of the offending object to help with debugging.
1494
Brett Cannonea3912b2006-06-13 21:46:41 +00001495- Bug #992017: A classic class that defined a __coerce__() method that returned
1496 its arguments swapped would infinitely recurse and segfault the interpreter.
1497
Neal Norwitz909eb122006-06-12 02:13:21 +00001498- Fix the socket tests so they can be run concurrently.
1499
Neal Norwitzb9845e72006-06-12 02:11:18 +00001500- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001501 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001502
Brett Cannon22565aa2006-06-09 22:31:23 +00001503- Bug #532646: object.__call__() will continue looking for the __call__
1504 attribute on objects until one without one is found. This leads to recursion
1505 when you take a class and set its __call__ attribute to an instance of the
1506 class. Originally fixed for classic classes, but this fix is for new-style.
1507 Removes the infinite_rec_3 crasher.
1508
Georg Brandl24250812006-06-09 18:45:48 +00001509- The string and unicode methods startswith() and endswith() now accept
1510 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1511
Brett Cannonde3b0522006-06-08 17:00:45 +00001512- Buffer objects, at the C level, never used the char buffer
1513 implementation even when the char buffer for the wrapped object was
1514 explicitly requested (originally returned the read or write buffer).
1515 Now a TypeError is raised if the char buffer is not present but is
1516 requested.
1517
Georg Brandlddbaa662006-06-04 21:56:52 +00001518- Patch #1346214: Statements like "if 0: suite" are now again optimized
1519 away like they were in Python 2.4.
1520
Georg Brandlb7c8f542006-05-27 12:30:25 +00001521- Builtin exceptions are now full-blown new-style classes instead of
1522 instances pretending to be classes, which speeds up exception handling
1523 by about 80% in comparison to 2.5a2.
1524
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001525- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1526 Unicode 4.1.
1527
Georg Brandlf4ef1162006-05-26 18:03:31 +00001528- Patch #921466: sys.path_importer_cache is now used to cache valid and
1529 invalid file paths for the built-in import machinery which leads to
1530 fewer open calls on startup.
1531
Tim Peters696cf432006-05-24 21:10:40 +00001532- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1533 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1534 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1535 the number of input digits (it was and remains linear-time for bases
1536 2, 4, 8, 16 and 32).
1537
Tim Petersb713ec22006-05-23 18:45:30 +00001538- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1539 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1540 an integer close to ``sys.maxint``. This was repaired by patch
1541 #1335972, which also gives a nice speedup.
1542
Richard Jonescebbefc2006-05-23 18:28:17 +00001543- Patch #1337051: reduced size of frame objects.
1544
1545- PyErr_NewException now accepts a tuple of base classes as its
1546 "base" parameter.
1547
Richard Jones7c88dcc2006-05-23 10:37:38 +00001548- Patch #876206: function call speedup by retaining allocated frame
1549 objects.
1550
Georg Brandl7b90e162006-05-18 07:01:27 +00001551- Bug #1462152: file() now checks more thoroughly for invalid mode
1552 strings and removes a possible "U" before passing the mode to the
1553 C library function.
1554
Neal Norwitz1004a532006-05-15 07:17:23 +00001555- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1556
Neal Norwitz373f0a72006-05-15 07:04:36 +00001557- Bug #1487966: Fix SystemError with conditional expression in assignment
1558
Martin v. Löwis879768d2006-05-11 13:28:43 +00001559- WindowsError now has two error code attributes: errno, which carries
1560 the error values from errno.h, and winerror, which carries the error
1561 values from winerror.h. Previous versions put the winerror.h values
1562 (from GetLastError()) into the errno attribute.
1563
Martin v. Löwis77736712006-05-04 05:51:03 +00001564- Patch #1475845: Raise IndentationError for unexpected indent.
1565
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001566- Patch #1479181: split open() and file() from being aliases for each other.
1567
Tim Peters44bd9862006-06-01 13:49:23 +00001568- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1569 methods were always silently ignored by dictionaries when comparing keys.
1570 They are now passed through (except when using the C API function
1571 ``PyDict_GetItem()``, whose semantics did not change).
1572
1573- Bug #1456209: In some obscure cases it was possible for a class with a
1574 custom ``__eq__()`` method to confuse dict internals when class instances
1575 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1576 No, you don't have any code that did this ;-)

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001578Extension Modules
1579-----------------
1580
Trent Mick960a3f82006-06-28 20:30:41 +00001581- Bug #1295808: expat symbols should be namespaced in pyexpat
1582
1583- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1584
Brett Cannon6ee7d012006-06-08 16:23:04 +00001585- Change binascii.hexlify to accept a read-only buffer instead of only a char
1586 buffer and actually follow its documentation.
1587
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001588- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1589
Nick Coghlanc649ec52006-05-29 12:43:05 +00001590- Patch #1478788 (modified version): The functional extension module has
1591 been renamed to _functools and a functools Python wrapper module added.
1592 This provides a home for additional function related utilities that are
1593 not specifically about functional programming. See PEP 309.
1594
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001595- Patch #1493701: performance enhancements for struct module.
1596
Georg Brandl378d5922006-05-17 14:26:50 +00001597- Patch #1490224: time.altzone is now set correctly on Cygwin.
1598
Georg Brandl8d3342b2006-05-16 07:38:27 +00001599- Patch #1435422: zlib's compress and decompress objects now have a
1600 copy() method.
1601
Andrew MacIntyre92913322006-06-13 15:04:24 +00001602- Patch #1454481: thread stack size is now tunable at runtime for thread
1603 enabled builds on Windows and systems with Posix threads support.
1604
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001605- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1606 (up to the system limit of 32K characters).
1607
1608- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1609 As a result, these functions now raise WindowsError instead of OSError.
1610
Tim Peters7a822da2006-05-25 21:50:17 +00001611- ``time.clock()`` on Win64 should use the high-performance Windows
1612 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1613 Windows platforms).
1614
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001615- Calling Tk_Init twice is refused if the first call failed as that
1616 may deadlock.
1617
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001618- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1619 accept it without potentially using an uninitialized pointer.
1620
1621- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1622 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1623 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001624
Gregory P. Smith372b5832006-06-05 18:48:21 +00001625- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001626 [pybsddb project SF patch number 1466734]
1627
Gregory P. Smith372b5832006-06-05 18:48:21 +00001628- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1629 parameter is supplied. [SF pybsddb bug #1477863]
1630
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001631- bsddb: the __len__ method of a DB object has been fixed to return correct
1632 results. It could previously incorrectly return 0 in some cases.
1633 Fixes SF bug 1493322 (pybsddb bug 1184012).
1634
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001635- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1636 aborts the db transaction safely when a modifier callback fails.
1637 Fixes SF python patch/bug #1408584.
1638
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001639- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001640 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001641 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1642 database calls that would previously deadlock. [SF python bug #775414]
1643
Vinay Sajip28e57612006-07-01 10:45:20 +00001644- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001645
Walter Dörwald4994d952006-06-19 08:07:50 +00001646- Patch #1506645: add Python wrappers for the curses functions
1647 is_term_resized, resize_term and resizeterm.

1650-------
1651
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001652- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1653 functions.
1654
Martin v. Löwis3798da02006-06-17 18:44:27 +00001655- Patch #812986: Update turtle output even if not tracing.
1656
Vinay Sajip28e57612006-07-01 10:45:20 +00001657- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001658 Tkinter.BaseWidget.
1659
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001660- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1661
Martin v. Löwis337487e2006-06-17 09:15:14 +00001662- Patch #763580: Add name and value arguments to Tkinter variable
1663 classes.
1664
Georg Brandl83cc0d02006-06-14 08:50:03 +00001665- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1666 mime.types file for determining MIME types.
1667
Georg Brandl2605ca82006-06-14 06:08:31 +00001668- Bug #1339007: Shelf objects now don't raise an exception in their
1669 __del__ method when initialization failed.
1670
Martin v. Löwisd8251432006-06-14 05:21:04 +00001671- Patch #1455898: The MBCS codec now supports the incremental mode for
1672 double-byte encodings.
1673
Tim Peters43898b42006-06-14 04:09:25 +00001674- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1675 guarantee that adjacent triples in the return list always describe
1676 non-adjacent blocks. Previously, a pair of matching blocks could end
1677 up being described by multiple adjacent triples that formed a partition
1678 of the matching pair.
1679
Greg Ward0e0c9f42006-06-11 16:24:11 +00001680- Bug #1498146: fix optparse to handle Unicode strings in option help,
1681 description, and epilog.
1682
Greg Wardd1c797e2006-06-11 14:42:41 +00001683- Bug #1366250: minor optparse documentation error.
1684
Greg Ward7f547402006-06-11 00:40:49 +00001685- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1686 clarify docs.
1687
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001688- The wsgiref package has been added to the standard library.
1689
Nick Coghlan676725d2006-06-08 13:54:49 +00001690- The functions update_wrapper() and wraps() have been added to the functools
1691 module. These make it easier to copy relevant metadata from the original
1692 function when writing wrapper functions.
1693
Tim Petersd6a9eef2006-06-05 01:48:21 +00001694- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1695 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001696
Martin v. Löwis3f767792006-06-04 19:36:28 +00001697- Patch #1359618: Speed up charmap encoder by using a trie structure
1698 for lookup.
1699
Tim Petersd609b1a2006-06-02 23:22:51 +00001700- The functions in the ``pprint`` module now sort dictionaries by key
1701 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1702 if and only if its display required more than one line, although that
1703 wasn't documented. The new behavior increases predictability; e.g.,
1704 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1705
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001706- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1707 (thanks for J. J. Lee).
1708
Georg Brandl2b330372006-05-28 20:23:12 +00001709- Patch #1496206: improve urllib2 handling of passwords with respect to
1710 default HTTP and HTTPS ports.
1711
George Yoshidaf3c65de2006-05-28 16:39:09 +00001712- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1713
Bob Ippolito7298f272006-05-23 18:43:47 +00001714- Patch #1281707: speed up gzip.readline.
1715
Georg Brandlb89316f2006-05-17 15:51:16 +00001716- Patch #1180296: Two new functions were added to the locale module:
1717 format_string() to get the effect of "format % items" but locale-aware,
1718 and currency() to format a monetary number with currency sign.
1719
Georg Brandle3a25832006-05-17 14:56:04 +00001720- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1721 and several features added, such as speed and geometry control.
1722
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001723- Patch #1488881: add support for external file objects in bz2 compressed
1724 tarfiles.
1725
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001726- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1727 stdout arguments, making it possible to redirect input and output
1728 for remote debugging.
1729
1730- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1731 a couple of issues, notably handling of long file names using the
1732 GNU LONGNAME extension.
1733
1734- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1735 new flag when ``name`` is already the name of an option flag.
1736
1737- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1738 package.
1739
1740- Patch #1472854: make the rlcompleter.Completer class usable on non-
1741 UNIX platforms.
1742
1743- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1744
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001745- Bug #1472827: correctly escape newlines and tabs in attribute values in
1746 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001776What's New in Python 2.5 alpha 2?
1777=================================
1778
1779*Release date: 27-APR-2006*
1780
1781Core and builtins
1782-----------------
1783
Thomas Heller1b046642006-04-18 18:51:06 +00001784- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1785 by converting these apis from macros into exported functions again:
1786
1787 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1788 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1789 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1790 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1791 PyRun_String Py_CompileString
1792
Martin v. Löwis45294a92006-04-18 06:24:08 +00001793- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1794
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001795- All uses of PyStructSequence_InitType have been changed to initialize
1796 the type objects only once, even if the interpreter is initialized
1797 multiple times.
1798
Neal Norwitz61546162006-04-14 05:20:28 +00001799- Bug #1454485, array.array('u') could crash the interpreter. This was
1800 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1801 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1802
1803- Py_UNICODE is unsigned. It was always documented as unsigned, but
1804 due to a bug had a signed value in previous versions.
1805
Tim Peters3a5e8b12006-04-11 01:44:07 +00001806- Patch #837242: ``id()`` of any Python object always gives a positive
1807 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1808 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001809 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001810 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001811
Tim Peters3a5e8b12006-04-11 01:44:07 +00001812 def __hash__(self):
1813 return id(self) # WRONG
1814
1815 because a hash result must be a (short) Python int but it was always
1816 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001817 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001818 was always usable as a hash value before this patch. That's no longer
1819 necessarily so.
1820
1821- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001822 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001823 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001824 #1454844)
1825
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001826- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1827 involving generators that have paused outside of any ``try`` or ``with``
1828 blocks. (In 2.5a1, a paused generator that was part of a reference
1829 cycle could not be garbage collected, regardless of whether it was
1830 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001831
Anthony Baxter51bcb682006-04-05 14:51:42 +00001832Extension Modules

1834
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001835- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1836 is a macro.
1837
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001838- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1839 fails with an error condition.
1840
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001841- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1842
1843- Bug #1117761: bsddb.*open() no longer raises an exception when using
1844 the cachesize parameter.
1845
1846- Bug #1149413: bsddb.*open() no longer raises an exception when using
1847 a temporary db (file=None) with the 'n' flag to truncate on open.
1848
1849- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1850 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001851
Armin Rigoa9017c32006-04-19 11:50:27 +00001852- Patch #1062014: AF_UNIX sockets under Linux have a special
1853 abstract namespace that is now fully supported.
1854
Anthony Baxter51bcb682006-04-05 14:51:42 +00001855Library
1856-------
1857
Peter Astrand7d1d4362006-07-14 14:04:45 +00001858- Bug #1223937: subprocess.CalledProcessError reports the exit status
1859 of the process using the returncode attribute, instead of
1860 abusing errno.
1861
Tim Peters711bf302006-04-25 03:31:36 +00001862- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1863 a doctest to be skipped (the code is not run, and the expected output
1864 or exception is ignored).
1865
Nick Coghlanda2268f2006-04-24 04:37:15 +00001866- Fixed contextlib.nested to cope with exceptions being raised and
1867 caught inside exit handlers.
1868
Greg Wardab05edc2006-04-23 03:47:58 +00001869- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1870 hex, octal, or binary; add ``append_const`` action; keep going if
1871 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1872 added ``epilog`` for better help generation).
1873
Tim Peters21fbd572006-04-21 21:18:10 +00001874- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1875 called from a thread spawned as a side effect of importing a module.
1876
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001877- The pydoc module now supports documenting packages contained in
1878 .zip or .egg files.
1879
1880- The pkgutil module now has several new utility functions, such
1881 as ``walk_packages()`` to support working with packages that are either
1882 in the filesystem or zip files.
1883
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001884- The mailbox module can now modify and delete messages from
1885 mailboxes, in addition to simply reading them. Thanks to Gregory
1886 K. Johnson for writing the code, and to the 2005 Google Summer of
1887 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001888
Tim Petersc7605f22006-04-17 21:12:33 +00001889- The ``__del__`` method of class ``local`` in module ``_threading_local``
1890 returned before accomplishing any of its intended cleanup.
1891
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001892- Patch #790710: Add breakpoint command lists in pdb.
1893
Martin v. Löwis0db2a982006-04-16 20:55:38 +00001894- Patch #1063914: Add Tkinter.Misc.clipboard_get().
1895
Martin v. Löwis4b501e62006-04-15 08:41:11 +00001896- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
1897
Anthony Baxtere29002c2006-04-12 12:07:31 +00001898- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1899 Windows. Bug #1469163.
1900
Phillip J. Eby47032112006-04-11 01:07:43 +00001901- The warnings, linecache, inspect, traceback, site, and doctest modules
1902 were updated to work correctly with modules imported from zipfiles or
1903 via other PEP 302 __loader__ objects.
1904
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001905- Patch #1467770: Reduce usage of subprocess._active to processes which
1906 the application hasn't waited on.
1907
Martin v. Löwisb04dee92006-04-10 08:34:21 +00001908- Patch #1462222: Fix Tix.Grid.
1909
Neal Norwitza31bf182006-04-09 03:35:43 +00001910- Fix exception when doing glob.glob('anything*/')
1911
Skip Montanaro262fb922006-04-21 02:31:07 +00001912- The pstats.Stats class accepts an optional stream keyword argument to
1913 direct output to an alternate file-like object.
1914
Anthony Baxter51bcb682006-04-05 14:51:42 +00001915Build
1916-----
1917
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001918- The Makefile now has a reindent target, which runs reindent.py on
1919 the library.
1920
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001921- Patch #1470875: Building Python with MS Free Compiler
1922
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00001923- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001924
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001925- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
1926 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001927 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001928 CXX from --with-cxx-main, see description in README.
1929
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001930- Patch #1429775: Link extension modules with the shared libpython.
1931
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001932- Fixed a libffi build problem on MIPS systems.
1933
Tim Peters8931ff12006-05-13 23:28:20 +00001934- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1935 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1936 and "%zu" for unsigned integers of type ``size_t``.
1937
Anthony Baxter51bcb682006-04-05 14:51:42 +00001938Tests
1939-----
1940
Nick Coghlanda2268f2006-04-24 04:37:15 +00001941- test_contextlib now checks contextlib.nested can cope with exceptions
1942 being raised and caught inside exit handlers.
1943
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001944- test_cmd_line now checks operation of the -m and -c command switches
1945
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001946- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1947 it separately and by hand. It also wasn't cleaning up its changes to
1948 the current Decimal context.
1949
Thomas Woutersabd08882006-04-26 15:53:30 +00001950- regrtest.py now has a -M option to run tests that test the new limits of
1951 containers, on 64-bit architectures. Running these tests is only sensible
1952 on 64-bit machines with more than two gigabytes of memory. The argument
1953 passed is the maximum amount of memory for the tests to use.
1954
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00001955Tools
1956-----
1957
1958- Added the Python benchmark suite pybench to the Tools/ directory;
1959 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001961Documentation
1962-------------
1963
Tim Petersb06d28c2006-05-12 01:57:59 +00001964- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
1965
Nick Coghlanc195d8a2006-04-24 03:04:43 +00001966- PEP 343: Added Context Types section to the library reference
1967 and attempted to bring other PEP 343 related documentation into
1968 line with the implementation and/or python-dev discussions.
1969
Tim Peters8dc73d22006-04-24 02:03:16 +00001970- Bug #1337990: clarified that ``doctest`` does not support examples
1971 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001974What's New in Python 2.5 alpha 1?
1975=================================
1976
Anthony Baxterebed3f62006-04-03 15:03:44 +00001977*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00001978
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00001979Core and builtins
1980-----------------
1981
Nick Coghlan43832302006-04-23 17:04:07 +00001982- PEP 338: -m command line switch now delegates to runpy.run_module
1983 allowing it to support modules in packages and zipfiles
1984
Martin v. Löwisc661b882006-04-20 04:54:23 +00001985- On Windows, .DLL is not an accepted file name extension for
1986 extension modules anymore; extensions are only found if they
1987 end in .PYD.
1988
Martin v. Löwisea62d252006-04-03 10:56:49 +00001989- Bug #1421664: sys.stderr.encoding is now set to the same value as
1990 sys.stdout.encoding.
1991
Neal Norwitz92e212f2006-04-03 04:48:37 +00001992- __import__ accepts keyword arguments.
1993
Georg Brandlccadf842006-03-31 18:54:53 +00001994- Patch #1460496: round() now accepts keyword arguments.
1995
Anthony Baxter262c00a2006-03-30 10:53:17 +00001996- Fixed bug #1459029 - unicode reprs were double-escaped.
1997
Hye-Shik Changd478f342006-03-23 12:32:36 +00001998- Patch #1396919: The system scope threads are reenabled on FreeBSD
1999 5.4 and later versions.
2000
Neal Norwitze98ccf62006-03-23 05:39:47 +00002001- Bug #1115379: Compiling a Unicode string with an encoding declaration
2002 now gives a SyntaxError.
2003
Georg Brandlabd1ff82006-03-18 07:59:59 +00002004- Previously, Python code had no easy way to access the contents of a
2005 cell object. Now, a ``cell_contents`` attribute has been added
2006 (closes patch #1170323).
2007
Tim Peterscf79aac2006-03-16 01:14:46 +00002008- Patch #1123430: Python's small-object allocator now returns an arena to
2009 the system ``free()`` when all memory within an arena becomes unused
2010 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2011 freed. Some applications will see a drop in virtual memory size now,
2012 especially long-running applications that, from time to time, temporarily
2013 use a large number of small objects. Note that when Python returns an
2014 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002015 platform C library will in turn return that memory to the operating system.
2016 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002017 appears to be effective at least on Microsoft C and gcc-based systems.
2018 Thanks to Evan Jones for hard work and patience.
2019
Georg Brandl533ff6f2006-03-08 18:09:27 +00002020- Patch #1434038: property() now uses the getter's docstring if there is
2021 no "doc" argument given. This makes it possible to legitimately use
2022 property() as a decorator to produce a read-only property.
2023
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002024- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2025 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2026 of requiring an int or long in slicing and a few other contexts, enabling
2027 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2028
Neal Norwitz995acdf2006-03-07 05:01:00 +00002029- Fixed various bugs reported by Coverity's Prevent tool.
2030
Brett Cannonbf364092006-03-01 04:25:17 +00002031- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2032 new exception base class, BaseException, which has a new message attribute.
2033 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2034 Raising a string exception now raises a DeprecationWarning.
2035
Thomas Woutersfb609f42006-02-28 16:37:25 +00002036- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2037 explicitly relative, using 'from .module import name' to mean 'from the same
2038 package as this module is in. Imports without dots still default to the
2039 old relative-then-absolute, unless 'from __future__ import
2040 absolute_import' is used.
2041
Brett Cannona7446e32006-02-27 23:39:10 +00002042- Properly check if 'warnings' raises an exception (usually when a filter set
2043 to "error" is triggered) when raising a warning for raising string
2044 exceptions.
2045
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002046- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002047 The name was removed from Include/code.h.
2048
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002049- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002050
Guido van Rossum1968ad32006-02-25 22:38:04 +00002051- Patch 1433928:
2052 - The copy module now "copies" function objects (as atomic objects).
2053 - dict.__getitem__ now looks for a __missing__ hook before raising
2054 KeyError.
2055
Tim Peters84ef21c2006-02-28 20:39:06 +00002056- PEP 343: with statement implemented. Needs ``from __future__ import
2057 with_statement``. Use of 'with' as a variable will generate a warning.
2058 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002059 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002060 The following objects have __context__ methods:
2061 - The built-in file type.
2062 - The thread.LockType type.
2063 - The following types defined by the threading module:
2064 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2065 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002066
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002067- Fix the encodings package codec search function to only search
2068 inside its own package. Fixes problem reported in patch #1433198.
2069
2070 Note: Codec packages should implement and register their own
2071 codec search function. PEP 100 has the details.
2072
Tim Peters9ea89d22006-06-04 03:26:02 +00002073- PEP 353: Using ``Py_ssize_t`` as the index type.
2074
2075- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2076 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2077 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2078 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2079 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002080
Neal Norwitzfc76d632006-01-10 06:03:13 +00002081- Patch #1400181, fix unicode string formatting to not use the locale.
2082 This is how string objects work. u'%f' could use , instead of .
2083 for the decimal point. Now both strings and unicode always use periods.
2084
Neal Norwitz671b9e32006-01-09 07:07:12 +00002085- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2086 configure would break checking curses.h.
2087
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002088- Bug #959576: The pwd module is now builtin. This allows Python to be
2089 built on UNIX platforms without $HOME set.
2090
Neal Norwitzc10978f2005-12-19 06:07:16 +00002091- Bug #1072182, fix some potential problems if characters are signed.
2092
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002093- Bug #889500, fix line number on SyntaxWarning for global declarations.
2094
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002095- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2096
Neal Norwitze7214a12005-12-18 05:03:17 +00002097- Support for converting hex strings to floats no longer works.
2098 This was not portable. float('0x3') now raises a ValueError.
2099
Barry Warsaw2a38a862005-12-18 01:27:35 +00002100- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002101 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002102 is now displayed in interactive prompt banner.
2103
Georg Brandlfa166682005-12-17 21:45:17 +00002104- Implementation of PEP 341 - Unification of try/except and try/finally.
2105 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002106 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002107
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002108- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2109 now encodes backslash correctly.
2110
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002111- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2112
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002113- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002114 and long longs.
2115
Neal Norwitz67715f02005-11-09 06:59:35 +00002116- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002117 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002118 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002119
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002120- Replaced most Unicode charmap codecs with new ones using the
2121 new Unicode translate string feature in the builtin charmap
2122 codec; the codecs were created from the mapping tables available
2123 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2124 encodings now include a mapping for the Apple logo)
2125
Tim Peterse3547fd2005-12-16 23:13:57 +00002126- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002127
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002128- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002129
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002130- A new AST parser implementation was completed. The abstract
2131 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002132 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002133
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002134- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002135 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2136
Neal Norwitz708e51a2005-10-03 04:48:15 +00002137- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2138
Neal Norwitz11bd1192005-10-03 00:54:56 +00002139- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2140 Provide a warning when a directory is passed on the command line.
2141
Neal Norwitz40d37812005-10-02 01:48:49 +00002142- Fix segfault with invalid coding.
2143
2144- SF bug #772896: unknown encoding results in MemoryError.
2145
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002146- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002147 supported a __len__() method which evaluated to False when the iterator
2148 was empty.
2149
Guido van Rossum630db602005-09-20 18:49:54 +00002150- On 64-bit platforms, when __len__() returns a value that cannot be
2151 represented as a C int, raise OverflowError.
2152
Skip Montanarof8948ca2005-09-19 03:54:46 +00002153- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002154 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002155
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002156- SF bug #893549: parsing keyword arguments was broken with a few format
2157 codes.
2158
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002159- Changes donated by Elemental Security to make it work on AIX 5.3
2160 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2161 bug #105470: test_pwd fails on 64bit system (Opteron).
2162
Guido van Rossum539c6622005-09-14 17:49:54 +00002163- Changes donated by Elemental Security to make it work on HP-UX 11 on
2164 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2165
Georg Brandl4550b8d2005-08-26 06:43:52 +00002166- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002167 (fixes bug #1119418).
2168
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002169- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2170
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002171- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2172 exceptions that cause a function to exit.
2173
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002174- The implementation of set() and frozenset() was revised to use its
2175 own internal data structure. Memory consumption is reduced by 1/3
2176 and there are modest speed-ups as well. The API is unchanged.
2177
Tim Petersde7990b2005-07-17 23:45:23 +00002178- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2179
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002180- SF bug #1229429: PyObject_CallMethod failed to decrement some
2181 reference counts in some error exit cases.
2182
Tim Petersecc6e6a2005-07-10 22:30:55 +00002183- SF bug #1185883: Python's small-object memory allocator took over
2184 a block managed by the platform C library whenever a realloc specified
2185 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002186 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002187 portable way to copy data from the C-managed block into Python's
2188 small-object space without risking a memory fault. Python's small-object
2189 realloc now leaves such blocks under the control of the platform C
2190 realloc.
2191
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002192- SF bug #1232517: An overflow error was not detected properly when
2193 attempting to convert a large float to an int in os.utime().
2194
Raymond Hettinger3296e692005-06-29 23:29:56 +00002195- SF bug #1224347: hex longs now print with lowercase letters just
2196 like their int counterparts.
2197
Michael W. Hudson188d4362005-06-20 16:52:57 +00002198- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2199 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2200 interpreter states; back out that fix and do a better job (see
2201 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2202 for a longer write-up of the problem).
2203
Michael W. Hudsondf888462005-06-03 14:41:55 +00002204- SF patch #1180995: marshal now uses a binary format by default when
2205 serializing floats.
2206
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002207- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2208 the routines that promise to produce IEEE 754 binary representations
2209 of floats now simply copy bytes around.
2210
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002211- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2212 278.
2213
Brett Cannonc3647ac2005-04-26 03:45:26 +00002214- patch #1109424: int, long, float, complex, and unicode now check for the
2215 proper magic slot for type conversions when subclassed. Previously the
2216 magic slot was ignored during conversion. Semantics now match the way
2217 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002218 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002219 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002220 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002221
Barry Warsawc8d907c2005-04-19 23:43:40 +00002222- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2223 NULL, now raise an AttributeError when attempting to set or delete the
2224 attribute. Previously a TypeError was raised, but this was inconsistent
2225 with the equivalent pure-Python implementation.
2226
Michael W. Hudson774479c2005-04-18 08:46:17 +00002227- It is now safe to call PyGILState_Release() before
2228 PyEval_InitThreads() (note that if there is reason to believe there
2229 are multiple threads around you still must call PyEval_InitThreads()
2230 before using the Python API; this fix is for extension modules that
2231 have no way of knowing if Python is multi-threaded yet).
2232
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002233- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2234 disabled caused a crash.
2235
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002236- Bug #1165306: instancemethod_new allowed the creation of a method
2237 with im_class == im_self == NULL, which caused a crash when called.
2238
Tim Petersecc6e6a2005-07-10 22:30:55 +00002239- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002240 fixes the crash seen in bug #1165761
2241
Raymond Hettinger96229b12005-03-11 06:49:40 +00002242- Added two new builtins, any() and all().
2243
Brett Cannon409d8f22005-03-05 06:47:57 +00002244- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002245 (e.g., ``class C(): pass`` is no longer a syntax error).
2246 Patch #1176012 added support to the 'parser' module and 'compiler' package
2247 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002248
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002249- Patch #1115086: Support PY_LONGLONG in structmember.
2250
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002251- Bug #1155938: new style classes did not check that __init__() was
2252 returning None.
2253
Tim Petersecc6e6a2005-07-10 22:30:55 +00002254- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002255 ('\') with a specific error message.
2256
Martin v. Löwisff232d72005-03-03 09:24:38 +00002257- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2258
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002259- Bug #1124295: the __name__ attribute of file objects was
2260 inadvertently made inaccessible in restricted mode.
2261
Tim Petersecc6e6a2005-07-10 22:30:55 +00002262- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002263 an ferror() call.
2264
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002265- min() and max() now support key= arguments with the same meaning as in
2266 list.sort().
2267
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002268- The peephole optimizer now performs simple constant folding in expressions:
2269 (2+3) --> (5).
2270
Raymond Hettingera422c342005-01-11 03:03:27 +00002271- set and frozenset objects can now be marshalled. SF #1098985.
2272
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002273- Bug #1077106: Poor argument checking could cause memory corruption
2274 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002275
Jeremy Hyltonab630502005-02-04 18:44:06 +00002276- The parser did not complain about future statements in illegal
2277 positions. It once again reports a syntax error if a future
2278 statement occurs after anything other than a doc string.
2279
Neil Schemenauercf52c072005-08-12 17:34:58 +00002280- Change the %s format specifier for str objects so that it returns a
2281 unicode instance if the argument is not an instance of basestring and
2282 calling __str__ on the argument returns a unicode instance.
2283
Tim Petersf4e69282006-02-27 17:15:31 +00002284- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2285 current thread state when the auto-GIL-state machinery knows about
2286 it (since the thread state is being deleted, continuing to remember it
2287 can't help, but can hurt if another thread happens to get created with
2288 the same thread id).
2289
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002290Extension Modules
2291-----------------
2292
Georg Brandl43f08a82006-03-31 18:01:16 +00002293- Patch #1380952: fix SSL objects timing out on consecutive read()s
2294
Neal Norwitz05a45592006-03-20 06:30:08 +00002295- Patch #1309579: wait3 and wait4 were added to the posix module.
2296
Anthony Baxterfa869072006-03-20 05:21:58 +00002297- Patch #1231053: The audioop module now supports encoding/decoding of alaw.
2298 In addition, the existing ulaw code was updated.
2299
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002300- RFE #567972: Socket objects' family, type and proto properties are
Georg Brandl72d7a782006-03-22 06:44:14 +00002301 now exposed via new attributes.
Georg Brandlbc45a3f2006-03-17 19:17:34 +00002302
Neal Norwitz10be10c2006-03-16 06:50:13 +00002303- Everything under lib-old was removed. This includes the following modules:
2304 Para, addpack, cmp, cmpcache, codehack, dircmp, dump, find, fmt, grep,
Tim Petersc9d78aa2006-03-26 23:27:58 +00002305 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00002306 util, whatsound, whrandom, zmod
2307
2308- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2309
2310- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002311 is deprecated. The undocumented re.engine variable no longer exists.
2312
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002313- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2314 SS2 (single-shift 2) escape sequences correctly.
2315
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002316- The unicodedata module was updated to the 4.1 version of the Unicode
2317 database. The 3.2 version is still available as unicodedata.db_3_2_0
2318 for applications that require this specific version (such as IDNA).
2319
Neal Norwitzb62c4332006-03-04 18:35:47 +00002320- The timing module is no longer built by default. It was deprecated

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002480- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2481 been renamed to have only a single underscore prefix. This was done to
2482 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002483
Nick Coghlan43832302006-04-23 17:04:07 +00002484- PEP 338: new module runpy defines a run_module function to support
2485 executing modules which provide access to source code or a code object
2486 via the PEP 302 import mechanisms.
2487
Anthony Baxter93f5b932006-04-03 08:05:07 +00002488- The email module's parsedate_tz function now sets the daylight savings

2496 in attribute values.
2497
Anthony Baxterc51ee692006-04-01 00:57:31 +00002498- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002499 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002500 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002501 module will not be built.
2502
Tim Petersc17976e2006-04-01 00:26:53 +00002503- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2504 aren't officially supported here, and trying to use them will probably
2505 raise an exception some day. But dicts have been allowed, and "mostly
2506 worked", so support for them won't go away without warning.
2507
Georg Brandl338ef7d2006-03-31 18:42:16 +00002508- Bug #1445068: getpass.getpass() can now be given an explicit stream
2509 argument to specify where to write the prompt.
2510

2526
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002527- email 4.0 package now integrated. This is largely the same as the email 3.0
2528 package that was included in Python 2.3, except that PEP 8 module names are
2529 now used (e.g. mail.message instead of email.Message). The MIME classes
2530 have been moved to a subpackage (e.g. email.mime.text instead of
2531 email.MIMEText). The old names are still supported for now. Several
2532 deprecated Message methods have been removed and lots of bugs have been
2533 fixed. More details can be found in the email package documentation.
2534
Walter Dörwald40108c92006-03-27 08:15:44 +00002535- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2536 (a subclass of tuple) that provides incremental decoders and encoders
2537 (a way to use stateful codecs without the stream API). Python functions
2538 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2539 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2540 have been added.

Walter Dörwald067db482006-03-15 22:17:27 +00002542- Patch #1359365: Calling next() on a closed StringIO.String object raises
2543 a ValueError instead of a StopIteration now (like file and cString.String do).
2544 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2545 called before (like file and StringIO.StringIO do).

Tim Petersda1329b2006-02-27 16:50:01 +00002594- Patch #1349118: urllib now supports user:pass@ style proxy
Martin v. Löwis3e865952006-01-24 15:51:21 +00002595 specifications, raises IOErrors when proxies for unsupported protocols
2596 are defined, and uses the https proxy on https redirections.

2613
Neal Norwitz338e7862005-12-23 21:27:46 +00002614- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
2615 LoadError as documented, instead of IOError. For compatibility,
2616 LoadError subclasses IOError.
2617
Brett Cannon3cbd0382005-12-16 22:49:23 +00002618- Added the hashlib module. It provides secure hash functions for MD5 and
Tim Peterse3547fd2005-12-16 23:13:57 +00002619 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2620 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2621 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2622 Ronald L. Rivest offered this advice for Python:
2623
2624 "The consensus of researchers in this area (at least as
2625 expressed at the NIST Hash Function Workshop 10/31/05),
2626 is that SHA-256 is a good choice for the time being, but
2627 that research should continue, and other alternatives may
2628 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002629
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002630- Added a subset of Fredrik Lundh's ElementTree package. Available

2723 Bug #1224621.
2724
Raymond Hettinger68c04532005-06-10 11:05:19 +00002725- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002726 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002727 the generate_tokens() function now accepts a callable argument that
2728 terminates by raising StopIteration.
2729
Georg Brandl9166e1a2005-06-04 09:20:03 +00002730- Bug #1196315: fix weakref.WeakValueDictionary constructor.

2745
Raymond Hettinger267b8682005-03-27 10:47:39 +00002746- decimal operator and comparison methods now return NotImplemented
2747 instead of raising a TypeError when interacting with other types. This
2748 allows other classes to implement __radd__ style methods and have them
2749 work as expected.
2750
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002751- Bug #1163325: Decimal infinities failed to hash. Attempting to

Guido van Rossumd0641422005-02-03 15:01:24 +00002789- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2790 disables recursive traversal through instance attributes, which can
2791 be exploited in various ways.
2792
Tim Peterse3547fd2005-12-16 23:13:57 +00002793- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002794 flags on the HTTP listening socket.
2795

2805
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002806- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2807
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002808- Enhancements to the csv module:
2809
2810 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002811 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002812 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002813 + Dialect parameter parsing has been re-implemented to improve error
2814 reporting.
2815 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2816 dictates.
2817 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002818 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002819 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002820 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2821 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002822 + reader now allows \r characters to be quoted (previously it only allowed
2823 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002824 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002825 + Dialect classes passed to the module are no longer instantiated by
2826 the module before being parsed (the former validation scheme required
2827 this, but the mechanism was unreliable).
2828 + The dialect registry now contains instances of the internal
2829 C-coded dialect type, rather than references to python objects.
2830 + the internal c-coded dialect type is now immutable.
2831 + register_dialect now accepts the same keyword dialect specifications
2832 as the reader and writer, allowing the user to register dialects
2833 without first creating a dialect class.
2834 + a configurable limit to the size of parsed fields has been added -
2835 previously, an unmatched quote character could result in the entire
2836 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002837 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002838 the parser field size limit (returning the former limit). The initial
2839 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002840 + A line_num attribute has been added to the reader object, which tracks
2841 the number of lines read from the source iterator. This is not
2842 the same as the number of records returned, as records can span
2843 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002844 + reader and writer objects were not being registered with the cyclic-GC.
2845 This has been fixed.
2846
Brett Cannone6539c42005-01-08 02:43:53 +00002847- _DummyThread objects in the threading module now delete self.__block that is
2848 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2849 lock primitives tend to be limited in number and thus should not be wasted on
2850 a _DummyThread object. Fixes bug #1089632.
2851
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002852- The imghdr module now detects Exif files.
2853
Raymond Hettinger6065d322004-12-20 23:51:53 +00002854- StringIO.truncate() now correctly adjusts the size attribute.
2855 (Bug #951915).
2856
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002857- locale.py now uses an updated locale alias table (built using
2858 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2859 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002860 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002861
Raymond Hettinger3557f422004-12-07 12:02:02 +00002862- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2863
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002864- the pickle module no longer accepts the deprecated None option in the
2865 args tuple returned by __reduce__().
2866
Brett Cannon84667c02004-12-07 03:25:18 +00002867- optparse now optionally imports gettext. This allows its use in setup.py.
2868
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002869- the pickle module no longer uses the deprecated bin parameter.
2870
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002871- the shelve module no longer uses the deprecated binary parameter.
2872
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002873- the pstats module no longer uses the deprecated ignore() method.
2874
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002875- the filecmp module no longer uses the deprecated use_statcache argument.
2876
Raymond Hettinger664347b2004-12-04 21:21:53 +00002877- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2878 extended or overridden by subclasses. Formerly, the subclassed method would
2879 be ignored by the rest of the module. (Bug #1078905).
2880
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002881- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002882 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002883
Walter Dörwald36733692004-12-22 12:50:50 +00002884- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2885 once when a size argument is given. This prevents a buffer overflow in the
2886 tokenizer with very long source lines.
2887
Barry Warsaw538561e2006-01-01 21:48:54 +00002888- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2889 immediately after creating the object, without any intervening
2890 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002891
Skip Montanaro05885812005-01-16 20:48:27 +00002892- The reconvert.quote function can now emit triple-quoted strings. The
2893 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002894
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002895- ``UserString.MutableString`` now supports negative indices in
2896 ``__setitem__`` and ``__delitem__``
2897
Greg Ward40407942005-03-05 02:53:17 +00002898- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2899 correctly.
2900
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002901- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2902 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2903 character even if the user has passed a size parameter to get a proper
2904 line ending. Remove the special handling of a "\r\n" that has been split
2905 between two lines.
2906
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002907- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2908 about illegal code points. The codec now supports PEP 293 style error
2909 handlers.
2910
Walter Dörwald78a78b02005-09-01 12:04:29 +00002911- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002912 from the input stream, so that the output is a byte string in the correct
2913 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002914
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002915- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2916 considering it exactly like a '*'.
2917
Walter Dörwald007f8df2005-10-09 19:42:27 +00002918- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2919 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002920
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002921- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2922
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002923- Patch #1413711: Certain patterns of differences were making difflib
2924 touch the recursion limit.
2925
Walter Dörwald58917a62006-03-31 15:26:22 +00002926- Bug #947906: An object oriented interface has been added to the calendar
2927 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002928 called as a script (e.g. via ``python -mcalendar``). Localized month and
2929 weekday names can be ouput (even if an exotic encoding is used) using
2930 special classes that use unicode.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002932Build
2933-----
2934
Neal Norwitz602d3392006-03-31 08:21:40 +00002935- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2936 by using -mieee gcc option.
2937
Martin v. Löwis86d66262006-02-17 08:40:11 +00002938- Patch #1432345: Make python compile on DragonFly.
2939
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002940- Build support for Win64-AMD64 was added.
2941
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002942- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2943
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002944- Patch #881820: look for openpty and forkpty also in libbsd.
2945
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002946- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2947 The zlib module is now builtin on Windows.
2948
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002949- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2950
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002951- Bug #1189330: configure did not correctly determine the necessary
2952 value of LINKCC if python was built with GCC 4.0.
2953
Trent Mick8321b422005-07-26 02:29:21 +00002954- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
2955 vulnerability in zlib 1.2.1 and 1.2.2.
2956
Brett Cannon08cd5982005-04-24 22:26:38 +00002957- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
2958 flags that change binary compatibility. Changes were also made to
2959 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00002960 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00002961
Bob Ippolitoed233462005-03-29 13:47:59 +00002962- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
2963 and linking has changed (prebinding is now deprecated, and libcc_dynamic
2964 no longer exists). This configure patch makes things right.
2965
Martin v. Löwise2713be2005-03-08 15:03:08 +00002966- Bug #1158607: Build with --disable-unicode again.
2967
Brett Cannon46d96232005-02-16 00:07:19 +00002968- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
2969 defined. Discovered as a result of not being able to build on OS X.
2970
Brett Cannon516592f2004-12-07 00:42:59 +00002971- setup.py now uses the directories specified in LDFLAGS using the -L option
2972 and in CPPFLAGS using the -I option for adding library and include
2973 directories, respectively, for compiling extension modules against. This has
2974 led to the core being compiled using the values in CPPFLAGS. It also removes
2975 the need for the special-casing of both DarwinPorts and Fink for darwin since
2976 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
2977 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
2978 Fink, ``-I/opt/local/include`` for DarwinPorts).
2979
Brett Cannon43802422005-02-10 20:48:03 +00002980- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
2981 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
2982 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
2983 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002985C API
2986-----
2987
Tim Petersc9d78aa2006-03-26 23:27:58 +00002988- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
2989 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
2990 is obtained via the ``PyObject_`` family, it must be released via the
2991 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
2992 always been officially true, but when Python's small-object allocator was
2993 introduced, an attempt was made to cater to a few extension modules
2994 discovered at the time that obtained memory via ``PyObject_New`` but
2995 released it via ``PyMem_DEL``. It's years later, and if such code still
2996 exists it will fail now (probably with segfaults, but calling wrong
2997 low-level memory management functions can yield many symptoms).
2998
Raymond Hettingerbeb31012005-08-16 03:47:52 +00002999- Added a C API for set and frozenset objects.
3000
Raymond Hettinger66517482004-12-03 11:45:13 +00003001- Removed PyRange_New().
3002
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003003- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3004 mapping argument now. This string is used as a mapping table. Byte values
3005 greater than the length of the string and 0xFFFE are treated as undefined
3006 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003013
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00003014- Patch #1276356: New resource "urlfetch" is implemented. This enables
