Georg Brandld59ea472007-03-08 18:37:35 +0000635- unittest now verifies more of its assumptions. In particular, TestCase
636 and TestSuite subclasses (not instances) are no longer accepted in
637 TestSuite.addTest(). This should cause no incompatibility since it

639 later, with a more cumbersome exception.

998
999- Fix concatenation (+=) of long strings.
1000
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001001- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001002 compared equal or unequal to a string and a UnicodeDecodeError
1003 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001004
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001005 Instead, the equal (==) and unequal (!=) comparison operators will
1006 now issue a UnicodeWarning and interpret the two objects as
1007 unequal. The UnicodeWarning can be filtered as desired using
1008 the warning framework, e.g. silenced completely, turned into an
1009 exception, logged, etc.
1010
1011 Note that compare operators other than equal and unequal will still
1012 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001013
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001014- Fix segfault when doing string formatting on subclasses of long.
1015
1016- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1017 with new-style classes.
1018
1019- Fix bug related to __len__ functions returning negative values with
1020 classic classes.
1021
1022- Patch #1538606, Fix __index__() clipping. There were some problems
1023 discovered with the API and how integers that didn't fit into Py_ssize_t
1024 were handled. This patch attempts to provide enough alternatives
1025 to effectively use __index__.
1026
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001027- Bug #1536021: __hash__ may now return long int; the final hash
1028 value is obtained by invoking hash on the long int.
1029
Thomas Hellerab1049c2006-08-08 17:37:00 +00001030- Bug #1536786: buffer comparison could emit a RuntimeWarning.

1033 sys.stdin is closed.
1034
Thomas Heller74d36f02006-08-04 18:17:40 +00001035- On Windows, the PyErr_Warn function is now exported from
1036 the Python dll again.
1037
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001038- Bug #1191458: tracing over for loops now produces a line event
1039 on each iteration. Fixing this problem required changing the .pyc
1040 magic number. This means that .pyc files generated before 2.5c1
1041 will be regenerated.
1042
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001043- Bug #1333982: string/number constants were inappropriately stored
1044 in the byte code and co_consts even if they were not used, ie
1045 immediately popped off the stack.
1046
Georg Brandle9462c72006-08-04 18:03:37 +00001047- Fixed a reference-counting problem in property().

1051-------
1052
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001053- Fix a bug in the ``compiler`` package that caused invalid code to be
1054 generated for generator expressions.
1055
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001056- The distutils version has been changed to 2.5.0. The change to
1057 keep it programmatically in sync with the Python version running
1058 the code (introduced in 2.5b3) has been reverted. It will continue
1059 to be maintained manually as static string literal.
1060
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001061- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001062 and this cannot be converted to the required C type, an exception is
1063 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001064 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001065
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001066- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001067 an exception.
1068
Tim Peterscbdd3502006-09-05 01:47:53 +00001069- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001070 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001071 workarounds for clocks with low resolution, to stop the code yielding
1072 duplicate UUIDs.
1073
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001074- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1075 before raising SystemExit, allowing IDLE to honor quit() and exit().
1076
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001077- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.

Georg Brandl7a1af772006-08-14 21:55:28 +00001079- Patch #1536071: trace.py should now find the full module name of a
1080 file correctly even on Windows.
1081
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001082- logging's atexit hook now runs even if the rest of the module has
1083 already been cleaned up.
1084

1088 str(exception) raised an exception.
1089
Neil Schemenauer06ded092006-08-04 16:20:30 +00001090- Fix a bug in the ``compiler`` package that caused invalid code to be

Thomas Heller86720042006-08-14 11:17:48 +00001107- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1108 uses the _as_parameter_ attribute when objects are passed to foreign
1109 function calls. The ctypes version number was changed to 1.0.1.
1110
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001111- Bug #1530559, struct.pack raises TypeError where it used to convert.

1164-----------------
1165
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001166- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001167 returned a long (see PEP 353).
1168
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001169- Bug #1515471: string.replace() accepts character buffers again.
1170
Neal Norwitz07aadb12006-07-30 06:55:48 +00001171- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1172 This provides the proper warning for struct.pack().
1173 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1174
Neal Norwitz0d62a062006-07-30 06:53:31 +00001175- Patch #1531113: Fix augmented assignment with yield expressions.

1177
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001178- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1179 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1180 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1181 excessive filesystem operations during imports.

Tim Petersbc24eee2006-07-27 01:14:53 +00001183- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1184 operations on signed longs that are formally undefined by C.
1185 Unfortunately, at least one compiler now cares about that, so complicated
1186 the code to make that compiler happy again.
1187
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001188- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1189
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001190- Patch #1232023: Stop including current directory in search
1191 path on Windows.
1192
Neal Norwitze1fdb322006-07-21 05:32:28 +00001193- Fix some potential crashes found with failmalloc.
1194
Neal Norwitze7563102006-07-17 01:00:16 +00001195- Fix warnings reported by Klocwork's static analysis tool.
1196
Neal Norwitz84be93b2006-07-16 01:50:38 +00001197- Bug #1512814, Fix incorrect lineno's when code within a function
1198 had more than 255 blank lines.
1199
Georg Brandl9dceedb2006-07-12 15:31:17 +00001200- Patch #1521179: Python now accepts the standard options ``--help`` and
1201 ``--version`` as well as ``/?`` on Windows.
1202
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001203- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001204 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001205 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001206
Tim Peters112aad32006-07-19 00:03:19 +00001207- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001208 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001209 new ``sys._current_frames()`` returns a dictionary with one entry,
1210 mapping the faux "thread id" 0 to the current frame.
1211
Ronald Oussoren3075e162006-07-25 20:28:55 +00001212- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

1217
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001218- Correction of patch #1455898: In the mbcs decoder, set final=False
1219 for stream decoder, but final=True for the decode function.
1220
Georg Brandl07fec3a2006-08-01 18:49:24 +00001221- os.urandom no longer masks unrelated exceptions like SystemExit or
1222 KeyboardInterrupt.
1223
Tim Peters4643c2f2006-08-10 22:45:34 +00001224- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001225 shutil.copytree on Windows
1226
Georg Brandle34ac7c2006-07-30 11:07:23 +00001227- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1228 refers to file descriptors, not file objects.
1229
Tim Peterscbdd3502006-09-05 01:47:53 +00001230- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001231 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001232 #1513611, and probably others.
1233
Georg Brandledd9b0d2006-07-29 09:33:26 +00001234- Bug #1441397: The compiler module now recognizes module and function
1235 docstrings correctly as it did in Python 2.4.
1236
Tim Peters6f681472006-07-27 23:44:37 +00001237- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1238 lost that tests are sorted by name before being run. This rarely
1239 matters for well-written tests, but can create baffling symptoms if
1240 side effects from one test to the next affect outcomes. ``DocTestFinder``
1241 has been changed to sort the list of tests it returns.
1242
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001243- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001244 in sync with sys.version_info[:3].

Martin v. Löwis9298eff2006-07-26 12:12:56 +00001246- Bug #978833: Really close underlying socket in _socketobject.close.
1247
Georg Brandldb232dc2006-08-20 13:15:43 +00001248- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1249 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001250
Georg Brandlcf0c1722006-07-26 07:23:32 +00001251- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1252 to recursive calls and call it with the failing package name.
1253
Martin v. Löwis0b483032006-07-25 09:53:12 +00001254- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1255
Georg Brandlc13c34c2006-07-24 14:09:56 +00001256- Patch #1515343: Fix printing of deprecated string exceptions with a
1257 value in the traceback module.
1258
Greg Ward48fae7a2006-07-23 16:05:51 +00001259- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1260
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001261- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1262
Brett Cannoncaebe222006-07-18 04:41:36 +00001263- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1264 argument tuple. For arguments where zero is illegal, the value is forced to
1265 the minimum value that is correct. This is to support an undocumented but
1266 common way people used to fill in inconsequential information in the time
1267 tuple pre-2.4.
1268
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001269- Patch #1220874: Update the binhex module for Mach-O.
1270
Barry Warsawb110bad2006-07-21 14:51:07 +00001271- The email package has improved RFC 2231 support, specifically for
1272 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1273 (name*0=<blah>) parameter continuations. This may change the types of
1274 values returned from email.message.Message.get_param() and friends.
1275 Specifically in some cases where non-encoded continuations were used,
1276 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1277 will just return the string (since non-encoded continuations don't have
1278 charset and language parts).
1279
1280 Also, whereas % values were decoded in all parameter continuations, they are
1281 now only decoded in encoded parameter parts.
1282
Ronald Oussoren3075e162006-07-25 20:28:55 +00001283- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1284
1285- Bug #1517996: IDLE now longer shows the default Tk menu when a
1286 path browser, class browser or debugger is the frontmost window on MacOS X
1287
Barry Warsaw00decd72006-07-27 23:43:15 +00001288- Patch #1520294: Support for getset and member descriptors in types.py,
1289 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1290 of an object against these built-in types and more importantly, for getting
1291 their docstrings printed in the interactive interpreter's help() function.

1295-----------------
1296
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001297- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1298 a socket operation on a socket with a timeout, the exception will be
1299 caught correctly. Previously, the exception was not caught.
1300
Thomas Heller1393d6a2006-07-28 21:43:20 +00001301- Patch #1529514: The _ctypes extension is now compiled on more
1302 openbsd target platforms.
1303
Tim Peters9cab5932006-07-28 00:30:00 +00001304- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1305 a memory leak, affecting pickles and deep copies.
1306
Tim Petersbc24eee2006-07-27 01:14:53 +00001307- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001308 Paul Eggert.
1309
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001310- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1311
Thomas Hellerce049a02006-07-14 17:51:14 +00001312- Patch #1521817: Index range checking on ctypes arrays containing
1313 exactly one element enabled again. This allows iterating over these
1314 arrays, without the need to check the array size before.
1315
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001316- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001317 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001318 /dev/null in certain cases; this is now fixed.
1319
Thomas Heller47d7a062006-07-12 08:43:47 +00001320- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1321 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001322
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001323- Because of a misspelled preprocessor symbol, ctypes was always
1324 compiled without thread support; this is now fixed.
1325
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001326- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1327 methods now allow their database parameter to be None as the
1328 sleepycat API allows.
1329
Matt Flemingec926502006-07-28 11:27:27 +00001330- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1331 bluetooth API compared with Linux and FreeBSD.
1332
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001333Tests
1334-----
1335
1336- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1337 how long the test file should take to play. Now accepts taking 2.93 secs
1338 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1339
Georg Brandl4793aa32006-07-28 18:31:39 +00001340- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1341 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1342 run via ``regrtest.py``. Now they do.

1351
1352- PythonLauncher now works correctly when the path to the script contains
1353 characters that are treated specially by the shell (such as quotes).
1354
1355- Bug #1527397: PythonLauncher now launches scripts with the working directory
1356 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001357 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001358 expect.

1367-----------------
1368
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001369- Bug #1441486: The literal representation of -(sys.maxint - 1)
1370 again evaluates to a int object, not a long.
1371
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001372- Bug #1501934: The scope of global variables that are locally assigned
1373 using augmented assignment is now correctly determined.
1374
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001375- Bug #927248: Recursive method-wrapper objects can now safely
1376 be released.
1377
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001378- Bug #1417699: Reject locale-specific decimal point in float()
1379 and atof().
1380
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001381- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1382 omit a default "error" argument for NULL pointer. This allows
1383 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001384
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001385- Bug #1519018: 'as' is now validated properly in import statements.
1386
Neal Norwitz28746ab2006-07-09 22:14:42 +00001387- On 64 bit systems, int literals that use less than 64 bits are
1388 now ints rather than longs.
1389
Neal Norwitzed657552006-07-10 00:04:44 +00001390- Bug #1512814, Fix incorrect lineno's when code at module scope
1391 started after line 256.
1392
Tim Peters32a83612006-07-10 21:08:24 +00001393- New function ``sys._current_frames()`` returns a dict mapping thread
1394 id to topmost thread stack frame. This is for expert use, and is
1395 especially useful for debugging application deadlocks. The functionality
1396 was previously available in Fazal Majid's ``threadframe`` extension
1397 module, but it wasn't possible to do this in a wholly threadsafe way from
1398 an extension.

1404 VS 2003.
1405
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001406- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1407
Tim Peters32a83612006-07-10 21:08:24 +00001408- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001409 environment variable to be set in order to the SDK environment
1410 for finding the compiler, include files, etc.

1415
Thomas Woutersadd19112006-07-05 11:03:49 +00001416- string.Template() now correctly handles tuple-values. Previously,
1417 multi-value tuples would raise an exception and single-value tuples would
1418 be treated as the value they contain, instead.
1419
Martin v. Löwisede77f52006-07-03 13:01:35 +00001420- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1421 even if some data are received.
1422
Martin v. Löwis45482392006-07-03 12:28:58 +00001423- Bug #1267547: Put proper recursive setup.py call into the
1424 spec file generated by bdist_rpm.
1425
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001426- Bug #1514693: Update turtle's heading when switching between
1427 degrees and radians.
1428
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001429- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001430 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001431
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001432- Bug #1514703: Only setup canvas window in turtle when the canvas
1433 is created.
1434
Martin v. Löwis7596e832006-07-01 15:33:37 +00001435- Bug #1513223: .close() of a _socketobj now releases the underlying
1436 socket again, which then gets closed as it becomes unreferenced.
1437
Fred Drake10497c82006-06-29 02:57:48 +00001438- Bug #1504333: Make sgmllib support angle brackets in quoted
1439 attribute values.
1440
1441- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1442 sgmllib ('[' and ']' were not accepted).
1443
Georg Brandl1be63af2006-06-28 20:23:25 +00001444- Fix a bug in the turtle module's end_fill function.
1445
Brett Cannon53ab5b72006-06-22 16:49:14 +00001446- Bug #1510580: The 'warnings' module improperly required that a Warning
1447 category be either a types.ClassType and a subclass of Warning. The proper
1448 check is just that it is a subclass with Warning as the documentation states.
1449
Georg Brandlad29e632006-06-21 17:45:17 +00001450- The compiler module now correctly compiles the new try-except-finally
1451 statement (bug #1509132).
1452
Neal Norwitz60373cd2006-06-22 06:30:50 +00001453- The wsgiref package is now installed properly on Unix.
1454
Vinay Sajip28e57612006-07-01 10:45:20 +00001455- A bug was fixed in logging.config.fileConfig() which caused a crash on
1456 shutdown when fileConfig() was called multiple times.
1457
Gerhard Häring762fbd32006-07-02 17:48:30 +00001458- The sqlite3 module did cut off data from the SQLite database at the first
1459 null character before sending it to a custom converter. This has been fixed
1460 now.

Tim Peters112aad32006-07-19 00:03:19 +00001465- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1466 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1467 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001468
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001469- Assigning None to pointer type fields in ctypes structures possible
1470 overwrote the wrong fields, this is fixed now.
1471
1472- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1473 on non-Windows platforms.
1474
1475- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1476 integer or long, without range checking.
1477
1478- Patch #1517790: It is now possible to use custom objects in the ctypes
1479 foreign function argtypes sequence as long as they provide a from_param
1480 method, no longer is it required that the object is a ctypes type.
1481
1482- The '_ctypes' extension module now works when Python is configured
1483 with the --without-threads option.
1484
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001485- Bug #1513646: os.access on Windows now correctly determines write
1486 access, again.
1487
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001488- Bug #1512695: cPickle.loads could crash if it was interrupted with
1489 a KeyboardInterrupt.
1490
Neal Norwitza12aa882006-07-06 06:45:08 +00001491- Bug #1296433: parsing XML with a non-default encoding and
1492 a CharacterDataHandler could crash the interpreter in pyexpat.
1493
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001494- Patch #1516912: improve Modules support for OpenVMS.

1497-----
1498
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001499- Automate Windows build process for the Win64 SSL module.
1500
Tim Peters32a83612006-07-10 21:08:24 +00001501- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001502 Previously, the slight difference could cause compilation errors of the
1503 'zlib' module on systems with more than one version of zlib.
1504
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001505- The MSI compileall step was fixed to also support a TARGETDIR
1506 with spaces in it.
1507
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001508- Bug #1517388: sqlite3.dll is now installed on Windows independent
1509 of Tcl/Tk.
1510
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001511- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001512 trying to be installed even though it's empty.

Nick Coghlan2d792252006-07-06 13:47:18 +00001523- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1524 documentation for the warnings module.
1525
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001526- Patch #1509163: MS Toolkit Compiler no longer available.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001535
1536Core and builtins
1537-----------------
1538
Georg Brandla56b9152006-06-19 06:35:54 +00001539- Patch #1507676: Error messages returned by invalid abstract object operations
1540 (such as iterating over an integer) have been improved and now include the
1541 type of the offending object to help with debugging.
1542
Brett Cannonea3912b2006-06-13 21:46:41 +00001543- Bug #992017: A classic class that defined a __coerce__() method that returned
1544 its arguments swapped would infinitely recurse and segfault the interpreter.
1545
Neal Norwitz909eb122006-06-12 02:13:21 +00001546- Fix the socket tests so they can be run concurrently.
1547
Neal Norwitzb9845e72006-06-12 02:11:18 +00001548- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001549 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001550
Brett Cannon22565aa2006-06-09 22:31:23 +00001551- Bug #532646: object.__call__() will continue looking for the __call__
1552 attribute on objects until one without one is found. This leads to recursion
1553 when you take a class and set its __call__ attribute to an instance of the
1554 class. Originally fixed for classic classes, but this fix is for new-style.
1555 Removes the infinite_rec_3 crasher.
1556
Georg Brandl24250812006-06-09 18:45:48 +00001557- The string and unicode methods startswith() and endswith() now accept
1558 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1559
Brett Cannonde3b0522006-06-08 17:00:45 +00001560- Buffer objects, at the C level, never used the char buffer
1561 implementation even when the char buffer for the wrapped object was
1562 explicitly requested (originally returned the read or write buffer).
1563 Now a TypeError is raised if the char buffer is not present but is
1564 requested.
1565
Georg Brandlddbaa662006-06-04 21:56:52 +00001566- Patch #1346214: Statements like "if 0: suite" are now again optimized
1567 away like they were in Python 2.4.
1568
Georg Brandlb7c8f542006-05-27 12:30:25 +00001569- Builtin exceptions are now full-blown new-style classes instead of
1570 instances pretending to be classes, which speeds up exception handling
1571 by about 80% in comparison to 2.5a2.
1572
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001573- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1574 Unicode 4.1.
1575
Georg Brandlf4ef1162006-05-26 18:03:31 +00001576- Patch #921466: sys.path_importer_cache is now used to cache valid and
1577 invalid file paths for the built-in import machinery which leads to
1578 fewer open calls on startup.
1579
Tim Peters696cf432006-05-24 21:10:40 +00001580- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1581 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1582 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1583 the number of input digits (it was and remains linear-time for bases
1584 2, 4, 8, 16 and 32).
1585
Tim Petersb713ec22006-05-23 18:45:30 +00001586- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1587 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1588 an integer close to ``sys.maxint``. This was repaired by patch
1589 #1335972, which also gives a nice speedup.
1590
Richard Jonescebbefc2006-05-23 18:28:17 +00001591- Patch #1337051: reduced size of frame objects.
1592
1593- PyErr_NewException now accepts a tuple of base classes as its
1594 "base" parameter.
1595
Richard Jones7c88dcc2006-05-23 10:37:38 +00001596- Patch #876206: function call speedup by retaining allocated frame
1597 objects.
1598
Georg Brandl7b90e162006-05-18 07:01:27 +00001599- Bug #1462152: file() now checks more thoroughly for invalid mode
1600 strings and removes a possible "U" before passing the mode to the
1601 C library function.
1602
Neal Norwitz1004a532006-05-15 07:17:23 +00001603- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1604
Neal Norwitz373f0a72006-05-15 07:04:36 +00001605- Bug #1487966: Fix SystemError with conditional expression in assignment
1606
Martin v. Löwis879768d2006-05-11 13:28:43 +00001607- WindowsError now has two error code attributes: errno, which carries
1608 the error values from errno.h, and winerror, which carries the error
1609 values from winerror.h. Previous versions put the winerror.h values
1610 (from GetLastError()) into the errno attribute.
1611
Martin v. Löwis77736712006-05-04 05:51:03 +00001612- Patch #1475845: Raise IndentationError for unexpected indent.
1613
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001614- Patch #1479181: split open() and file() from being aliases for each other.
1615
Tim Peters44bd9862006-06-01 13:49:23 +00001616- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1617 methods were always silently ignored by dictionaries when comparing keys.
1618 They are now passed through (except when using the C API function
1619 ``PyDict_GetItem()``, whose semantics did not change).
1620
1621- Bug #1456209: In some obscure cases it was possible for a class with a
1622 custom ``__eq__()`` method to confuse dict internals when class instances
1623 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1624 No, you don't have any code that did this ;-)

1627-----------------
1628
Trent Mick960a3f82006-06-28 20:30:41 +00001629- Bug #1295808: expat symbols should be namespaced in pyexpat
1630
1631- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1632
Brett Cannon6ee7d012006-06-08 16:23:04 +00001633- Change binascii.hexlify to accept a read-only buffer instead of only a char
1634 buffer and actually follow its documentation.
1635
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001636- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1637
Nick Coghlanc649ec52006-05-29 12:43:05 +00001638- Patch #1478788 (modified version): The functional extension module has
1639 been renamed to _functools and a functools Python wrapper module added.
1640 This provides a home for additional function related utilities that are
1641 not specifically about functional programming. See PEP 309.
1642
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001643- Patch #1493701: performance enhancements for struct module.
1644
Georg Brandl378d5922006-05-17 14:26:50 +00001645- Patch #1490224: time.altzone is now set correctly on Cygwin.
1646
Georg Brandl8d3342b2006-05-16 07:38:27 +00001647- Patch #1435422: zlib's compress and decompress objects now have a
1648 copy() method.
1649
Andrew MacIntyre92913322006-06-13 15:04:24 +00001650- Patch #1454481: thread stack size is now tunable at runtime for thread
1651 enabled builds on Windows and systems with Posix threads support.
1652
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001653- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1654 (up to the system limit of 32K characters).
1655
1656- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1657 As a result, these functions now raise WindowsError instead of OSError.
1658
Tim Peters7a822da2006-05-25 21:50:17 +00001659- ``time.clock()`` on Win64 should use the high-performance Windows
1660 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1661 Windows platforms).
1662
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001663- Calling Tk_Init twice is refused if the first call failed as that
1664 may deadlock.
1665
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001666- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1667 accept it without potentially using an uninitialized pointer.
1668
1669- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1670 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1671 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001672
Gregory P. Smith372b5832006-06-05 18:48:21 +00001673- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001674 [pybsddb project SF patch number 1466734]
1675
Gregory P. Smith372b5832006-06-05 18:48:21 +00001676- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1677 parameter is supplied. [SF pybsddb bug #1477863]
1678
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001679- bsddb: the __len__ method of a DB object has been fixed to return correct
1680 results. It could previously incorrectly return 0 in some cases.
1681 Fixes SF bug 1493322 (pybsddb bug 1184012).
1682
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001683- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1684 aborts the db transaction safely when a modifier callback fails.
1685 Fixes SF python patch/bug #1408584.
1686
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001687- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001688 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001689 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1690 database calls that would previously deadlock. [SF python bug #775414]
1691
Vinay Sajip28e57612006-07-01 10:45:20 +00001692- Patch #1446489: add support for the ZIP64 extensions to zipfile.
Gregory P. Smith372b5832006-06-05 18:48:21 +00001693
Walter Dörwald4994d952006-06-19 08:07:50 +00001694- Patch #1506645: add Python wrappers for the curses functions
1695 is_term_resized, resize_term and resizeterm.

1698-------
1699
Martin v. Löwis6fb20aa2006-06-17 19:03:26 +00001700- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
1701 functions.
1702
Martin v. Löwis3798da02006-06-17 18:44:27 +00001703- Patch #812986: Update turtle output even if not tracing.
1704
Vinay Sajip28e57612006-07-01 10:45:20 +00001705- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001706 Tkinter.BaseWidget.
1707
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001708- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1709
Martin v. Löwis337487e2006-06-17 09:15:14 +00001710- Patch #763580: Add name and value arguments to Tkinter variable
1711 classes.
1712
Georg Brandl83cc0d02006-06-14 08:50:03 +00001713- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1714 mime.types file for determining MIME types.
1715
Georg Brandl2605ca82006-06-14 06:08:31 +00001716- Bug #1339007: Shelf objects now don't raise an exception in their
1717 __del__ method when initialization failed.
1718
Martin v. Löwisd8251432006-06-14 05:21:04 +00001719- Patch #1455898: The MBCS codec now supports the incremental mode for
1720 double-byte encodings.
1721
Tim Peters43898b42006-06-14 04:09:25 +00001722- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1723 guarantee that adjacent triples in the return list always describe
1724 non-adjacent blocks. Previously, a pair of matching blocks could end
1725 up being described by multiple adjacent triples that formed a partition
1726 of the matching pair.
1727
Greg Ward0e0c9f42006-06-11 16:24:11 +00001728- Bug #1498146: fix optparse to handle Unicode strings in option help,
1729 description, and epilog.
1730
Greg Wardd1c797e2006-06-11 14:42:41 +00001731- Bug #1366250: minor optparse documentation error.
1732
Greg Ward7f547402006-06-11 00:40:49 +00001733- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1734 clarify docs.
1735
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001736- The wsgiref package has been added to the standard library.
1737
Nick Coghlan676725d2006-06-08 13:54:49 +00001738- The functions update_wrapper() and wraps() have been added to the functools
1739 module. These make it easier to copy relevant metadata from the original
1740 function when writing wrapper functions.
1741
Tim Petersd6a9eef2006-06-05 01:48:21 +00001742- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1743 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001744
Martin v. Löwis3f767792006-06-04 19:36:28 +00001745- Patch #1359618: Speed up charmap encoder by using a trie structure
1746 for lookup.
1747
Tim Petersd609b1a2006-06-02 23:22:51 +00001748- The functions in the ``pprint`` module now sort dictionaries by key
1749 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1750 if and only if its display required more than one line, although that
1751 wasn't documented. The new behavior increases predictability; e.g.,

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001824What's New in Python 2.5 alpha 2?
1825=================================
1826
1827*Release date: 27-APR-2006*
1828
1829Core and builtins
1830-----------------
1831
Thomas Heller1b046642006-04-18 18:51:06 +00001832- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1833 by converting these apis from macros into exported functions again:
1834
1835 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1836 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1837 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1838 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1839 PyRun_String Py_CompileString
1840
Martin v. Löwis45294a92006-04-18 06:24:08 +00001841- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1842
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001843- All uses of PyStructSequence_InitType have been changed to initialize
1844 the type objects only once, even if the interpreter is initialized
1845 multiple times.
1846
Neal Norwitz61546162006-04-14 05:20:28 +00001847- Bug #1454485, array.array('u') could crash the interpreter. This was
1848 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1849 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1850
1851- Py_UNICODE is unsigned. It was always documented as unsigned, but
1852 due to a bug had a signed value in previous versions.
1853
Tim Peters3a5e8b12006-04-11 01:44:07 +00001854- Patch #837242: ``id()`` of any Python object always gives a positive
1855 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1856 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001857 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001858 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001859
Tim Peters3a5e8b12006-04-11 01:44:07 +00001860 def __hash__(self):
1861 return id(self) # WRONG
1862
1863 because a hash result must be a (short) Python int but it was always
1864 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001865 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001866 was always usable as a hash value before this patch. That's no longer
1867 necessarily so.
1868
1869- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001870 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001871 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001872 #1454844)
1873
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001874- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1875 involving generators that have paused outside of any ``try`` or ``with``
1876 blocks. (In 2.5a1, a paused generator that was part of a reference
1877 cycle could not be garbage collected, regardless of whether it was
1878 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001879

Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001886- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1887 fails with an error condition.
1888
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001889- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1890
1891- Bug #1117761: bsddb.*open() no longer raises an exception when using
1892 the cachesize parameter.
1893
1894- Bug #1149413: bsddb.*open() no longer raises an exception when using
1895 a temporary db (file=None) with the 'n' flag to truncate on open.
1896
1897- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1898 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001899
Armin Rigoa9017c32006-04-19 11:50:27 +00001900- Patch #1062014: AF_UNIX sockets under Linux have a special
1901 abstract namespace that is now fully supported.

1907 of the process using the returncode attribute, instead of
1908 abusing errno.
1909
Tim Peters711bf302006-04-25 03:31:36 +00001910- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1911 a doctest to be skipped (the code is not run, and the expected output
1912 or exception is ignored).
1913
Nick Coghlanda2268f2006-04-24 04:37:15 +00001914- Fixed contextlib.nested to cope with exceptions being raised and
1915 caught inside exit handlers.
1916
Greg Wardab05edc2006-04-23 03:47:58 +00001917- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1918 hex, octal, or binary; add ``append_const`` action; keep going if
1919 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1920 added ``epilog`` for better help generation).
1921
Tim Peters21fbd572006-04-21 21:18:10 +00001922- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1923 called from a thread spawned as a side effect of importing a module.
1924
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001925- The pydoc module now supports documenting packages contained in
1926 .zip or .egg files.
1927
1928- The pkgutil module now has several new utility functions, such
1929 as ``walk_packages()`` to support working with packages that are either
1930 in the filesystem or zip files.
1931
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001932- The mailbox module can now modify and delete messages from
1933 mailboxes, in addition to simply reading them. Thanks to Gregory
1934 K. Johnson for writing the code, and to the 2005 Google Summer of
1935 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001936
Tim Petersc7605f22006-04-17 21:12:33 +00001937- The ``__del__`` method of class ``local`` in module ``_threading_local``
1938 returned before accomplishing any of its intended cleanup.
1939
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001940- Patch #790710: Add breakpoint command lists in pdb.
1941

1945
Anthony Baxtere29002c2006-04-12 12:07:31 +00001946- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1947 Windows. Bug #1469163.
1948
Phillip J. Eby47032112006-04-11 01:07:43 +00001949- The warnings, linecache, inspect, traceback, site, and doctest modules
1950 were updated to work correctly with modules imported from zipfiles or
1951 via other PEP 302 __loader__ objects.
1952
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001953- Patch #1467770: Reduce usage of subprocess._active to processes which
1954 the application hasn't waited on.
1955

1964-----
1965
Martin v. Löwis4be4e652006-04-17 19:25:49 +00001966- The Makefile now has a reindent target, which runs reindent.py on
1967 the library.
1968
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00001969- Patch #1470875: Building Python with MS Free Compiler

1974 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00001975 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00001976 CXX from --with-cxx-main, see description in README.
1977
Martin v. Löwis10acfd02006-04-10 12:39:36 +00001978- Patch #1429775: Link extension modules with the shared libpython.
1979
Hye-Shik Changf4795c82006-04-26 19:20:26 +00001980- Fixed a libffi build problem on MIPS systems.
1981
Tim Peters8931ff12006-05-13 23:28:20 +00001982- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
1983 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
1984 and "%zu" for unsigned integers of type ``size_t``.
1985
Anthony Baxter51bcb682006-04-05 14:51:42 +00001986Tests
1987-----
1988
Nick Coghlanda2268f2006-04-24 04:37:15 +00001989- test_contextlib now checks contextlib.nested can cope with exceptions
1990 being raised and caught inside exit handlers.
1991
Nick Coghlan27ec1a72006-04-24 04:32:47 +00001992- test_cmd_line now checks operation of the -m and -c command switches
1993
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001994- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
1995 it separately and by hand. It also wasn't cleaning up its changes to
1996 the current Decimal context.
1997
Thomas Woutersabd08882006-04-26 15:53:30 +00001998- regrtest.py now has a -M option to run tests that test the new limits of
1999 containers, on 64-bit architectures. Running these tests is only sensible
2000 on 64-bit machines with more than two gigabytes of memory. The argument
2001 passed is the maximum amount of memory for the tests to use.

Tim Petersb06d28c2006-05-12 01:57:59 +00002012- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2013
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002014- PEP 343: Added Context Types section to the library reference
2015 and attempted to bring other PEP 343 related documentation into
2016 line with the implementation and/or python-dev discussions.
2017
Tim Peters8dc73d22006-04-24 02:03:16 +00002018- Bug #1337990: clarified that ``doctest`` does not support examples

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002022What's New in Python 2.5 alpha 1?
2023=================================
2024
Anthony Baxterebed3f62006-04-03 15:03:44 +00002025*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002026
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002027Core and builtins
2028-----------------
2029
Nick Coghlan43832302006-04-23 17:04:07 +00002030- PEP 338: -m command line switch now delegates to runpy.run_module
2031 allowing it to support modules in packages and zipfiles
2032
Martin v. Löwisc661b882006-04-20 04:54:23 +00002033- On Windows, .DLL is not an accepted file name extension for
2034 extension modules anymore; extensions are only found if they
2035 end in .PYD.
2036
Martin v. Löwisea62d252006-04-03 10:56:49 +00002037- Bug #1421664: sys.stderr.encoding is now set to the same value as
2038 sys.stdout.encoding.
2039
Neal Norwitz92e212f2006-04-03 04:48:37 +00002040- __import__ accepts keyword arguments.
2041
Georg Brandlccadf842006-03-31 18:54:53 +00002042- Patch #1460496: round() now accepts keyword arguments.
2043
Anthony Baxter262c00a2006-03-30 10:53:17 +00002044- Fixed bug #1459029 - unicode reprs were double-escaped.
2045
Hye-Shik Changd478f342006-03-23 12:32:36 +00002046- Patch #1396919: The system scope threads are reenabled on FreeBSD
2047 5.4 and later versions.
2048
Neal Norwitze98ccf62006-03-23 05:39:47 +00002049- Bug #1115379: Compiling a Unicode string with an encoding declaration
2050 now gives a SyntaxError.
2051
Georg Brandlabd1ff82006-03-18 07:59:59 +00002052- Previously, Python code had no easy way to access the contents of a
2053 cell object. Now, a ``cell_contents`` attribute has been added
2054 (closes patch #1170323).
2055
Tim Peterscf79aac2006-03-16 01:14:46 +00002056- Patch #1123430: Python's small-object allocator now returns an arena to
2057 the system ``free()`` when all memory within an arena becomes unused
2058 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2059 freed. Some applications will see a drop in virtual memory size now,
2060 especially long-running applications that, from time to time, temporarily
2061 use a large number of small objects. Note that when Python returns an
2062 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002063 platform C library will in turn return that memory to the operating system.
2064 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002065 appears to be effective at least on Microsoft C and gcc-based systems.
2066 Thanks to Evan Jones for hard work and patience.
2067
Georg Brandl533ff6f2006-03-08 18:09:27 +00002068- Patch #1434038: property() now uses the getter's docstring if there is
2069 no "doc" argument given. This makes it possible to legitimately use
2070 property() as a decorator to produce a read-only property.
2071
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002072- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2073 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2074 of requiring an int or long in slicing and a few other contexts, enabling
2075 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2076
Neal Norwitz995acdf2006-03-07 05:01:00 +00002077- Fixed various bugs reported by Coverity's Prevent tool.
2078
Brett Cannonbf364092006-03-01 04:25:17 +00002079- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2080 new exception base class, BaseException, which has a new message attribute.
2081 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2082 Raising a string exception now raises a DeprecationWarning.
2083
Thomas Woutersfb609f42006-02-28 16:37:25 +00002084- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2085 explicitly relative, using 'from .module import name' to mean 'from the same
2086 package as this module is in. Imports without dots still default to the
2087 old relative-then-absolute, unless 'from __future__ import
2088 absolute_import' is used.
2089
Brett Cannona7446e32006-02-27 23:39:10 +00002090- Properly check if 'warnings' raises an exception (usually when a filter set
2091 to "error" is triggered) when raising a warning for raising string
2092 exceptions.
2093
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002094- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002095 The name was removed from Include/code.h.
2096
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002097- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002098
Guido van Rossum1968ad32006-02-25 22:38:04 +00002099- Patch 1433928:
2100 - The copy module now "copies" function objects (as atomic objects).
2101 - dict.__getitem__ now looks for a __missing__ hook before raising
2102 KeyError.
2103
Tim Peters84ef21c2006-02-28 20:39:06 +00002104- PEP 343: with statement implemented. Needs ``from __future__ import
2105 with_statement``. Use of 'with' as a variable will generate a warning.
2106 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002107 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002108 The following objects have __context__ methods:
2109 - The built-in file type.
2110 - The thread.LockType type.
2111 - The following types defined by the threading module:
2112 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2113 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002114
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002115- Fix the encodings package codec search function to only search
2116 inside its own package. Fixes problem reported in patch #1433198.
2117
2118 Note: Codec packages should implement and register their own
2119 codec search function. PEP 100 has the details.
2120
Tim Peters9ea89d22006-06-04 03:26:02 +00002121- PEP 353: Using ``Py_ssize_t`` as the index type.
2122
2123- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2124 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2125 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2126 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2127 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002128
Neal Norwitzfc76d632006-01-10 06:03:13 +00002129- Patch #1400181, fix unicode string formatting to not use the locale.
2130 This is how string objects work. u'%f' could use , instead of .
2131 for the decimal point. Now both strings and unicode always use periods.
2132
Neal Norwitz671b9e32006-01-09 07:07:12 +00002133- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2134 configure would break checking curses.h.
2135
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002136- Bug #959576: The pwd module is now builtin. This allows Python to be
2137 built on UNIX platforms without $HOME set.
2138
Neal Norwitzc10978f2005-12-19 06:07:16 +00002139- Bug #1072182, fix some potential problems if characters are signed.
2140
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002141- Bug #889500, fix line number on SyntaxWarning for global declarations.
2142
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002143- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2144
Neal Norwitze7214a12005-12-18 05:03:17 +00002145- Support for converting hex strings to floats no longer works.
2146 This was not portable. float('0x3') now raises a ValueError.
2147
Barry Warsaw2a38a862005-12-18 01:27:35 +00002148- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002149 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002150 is now displayed in interactive prompt banner.
2151
Georg Brandlfa166682005-12-17 21:45:17 +00002152- Implementation of PEP 341 - Unification of try/except and try/finally.
2153 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002154 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002155
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002156- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2157 now encodes backslash correctly.
2158
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002159- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2160
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002161- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002162 and long longs.
2163
Neal Norwitz67715f02005-11-09 06:59:35 +00002164- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002165 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002166 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002167
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002168- Replaced most Unicode charmap codecs with new ones using the
2169 new Unicode translate string feature in the builtin charmap
2170 codec; the codecs were created from the mapping tables available
2171 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2172 encodings now include a mapping for the Apple logo)
2173
Tim Peterse3547fd2005-12-16 23:13:57 +00002174- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002175
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002176- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002177
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002178- A new AST parser implementation was completed. The abstract
2179 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002180 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002181
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002182- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002183 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2184
Neal Norwitz708e51a2005-10-03 04:48:15 +00002185- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2186
Neal Norwitz11bd1192005-10-03 00:54:56 +00002187- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2188 Provide a warning when a directory is passed on the command line.
2189
Neal Norwitz40d37812005-10-02 01:48:49 +00002190- Fix segfault with invalid coding.
2191
2192- SF bug #772896: unknown encoding results in MemoryError.
2193
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002194- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002195 supported a __len__() method which evaluated to False when the iterator
2196 was empty.
2197
Guido van Rossum630db602005-09-20 18:49:54 +00002198- On 64-bit platforms, when __len__() returns a value that cannot be
2199 represented as a C int, raise OverflowError.
2200
Skip Montanarof8948ca2005-09-19 03:54:46 +00002201- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002202 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002203
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002204- SF bug #893549: parsing keyword arguments was broken with a few format
2205 codes.
2206
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002207- Changes donated by Elemental Security to make it work on AIX 5.3
2208 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2209 bug #105470: test_pwd fails on 64bit system (Opteron).
2210
Guido van Rossum539c6622005-09-14 17:49:54 +00002211- Changes donated by Elemental Security to make it work on HP-UX 11 on
2212 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2213
Georg Brandl4550b8d2005-08-26 06:43:52 +00002214- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002215 (fixes bug #1119418).
2216
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002217- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2218
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002219- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2220 exceptions that cause a function to exit.
2221
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002222- The implementation of set() and frozenset() was revised to use its
2223 own internal data structure. Memory consumption is reduced by 1/3
2224 and there are modest speed-ups as well. The API is unchanged.
2225
Tim Petersde7990b2005-07-17 23:45:23 +00002226- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2227
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002228- SF bug #1229429: PyObject_CallMethod failed to decrement some
2229 reference counts in some error exit cases.
2230
Tim Petersecc6e6a2005-07-10 22:30:55 +00002231- SF bug #1185883: Python's small-object memory allocator took over
2232 a block managed by the platform C library whenever a realloc specified
2233 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002234 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002235 portable way to copy data from the C-managed block into Python's
2236 small-object space without risking a memory fault. Python's small-object
2237 realloc now leaves such blocks under the control of the platform C
2238 realloc.
2239
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002240- SF bug #1232517: An overflow error was not detected properly when
2241 attempting to convert a large float to an int in os.utime().
2242
Raymond Hettinger3296e692005-06-29 23:29:56 +00002243- SF bug #1224347: hex longs now print with lowercase letters just
2244 like their int counterparts.
2245
Michael W. Hudson188d4362005-06-20 16:52:57 +00002246- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2247 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2248 interpreter states; back out that fix and do a better job (see
2249 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2250 for a longer write-up of the problem).
2251
Michael W. Hudsondf888462005-06-03 14:41:55 +00002252- SF patch #1180995: marshal now uses a binary format by default when
2253 serializing floats.
2254
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002255- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2256 the routines that promise to produce IEEE 754 binary representations
2257 of floats now simply copy bytes around.
2258
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002259- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2260 278.
2261
Brett Cannonc3647ac2005-04-26 03:45:26 +00002262- patch #1109424: int, long, float, complex, and unicode now check for the
2263 proper magic slot for type conversions when subclassed. Previously the
2264 magic slot was ignored during conversion. Semantics now match the way
2265 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002266 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002267 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002268 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002269
Barry Warsawc8d907c2005-04-19 23:43:40 +00002270- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2271 NULL, now raise an AttributeError when attempting to set or delete the
2272 attribute. Previously a TypeError was raised, but this was inconsistent
2273 with the equivalent pure-Python implementation.
2274
Michael W. Hudson774479c2005-04-18 08:46:17 +00002275- It is now safe to call PyGILState_Release() before
2276 PyEval_InitThreads() (note that if there is reason to believe there
2277 are multiple threads around you still must call PyEval_InitThreads()
2278 before using the Python API; this fix is for extension modules that
2279 have no way of knowing if Python is multi-threaded yet).
2280
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002281- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2282 disabled caused a crash.
2283
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002284- Bug #1165306: instancemethod_new allowed the creation of a method
2285 with im_class == im_self == NULL, which caused a crash when called.
2286
Tim Petersecc6e6a2005-07-10 22:30:55 +00002287- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002288 fixes the crash seen in bug #1165761
2289
Raymond Hettinger96229b12005-03-11 06:49:40 +00002290- Added two new builtins, any() and all().
2291
Brett Cannon409d8f22005-03-05 06:47:57 +00002292- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002293 (e.g., ``class C(): pass`` is no longer a syntax error).
2294 Patch #1176012 added support to the 'parser' module and 'compiler' package
2295 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002296
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002297- Patch #1115086: Support PY_LONGLONG in structmember.
2298
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002299- Bug #1155938: new style classes did not check that __init__() was
2300 returning None.
2301
Tim Petersecc6e6a2005-07-10 22:30:55 +00002302- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002303 ('\') with a specific error message.
2304
Martin v. Löwisff232d72005-03-03 09:24:38 +00002305- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2306
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002307- Bug #1124295: the __name__ attribute of file objects was
2308 inadvertently made inaccessible in restricted mode.
2309
Tim Petersecc6e6a2005-07-10 22:30:55 +00002310- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002311 an ferror() call.
2312
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002313- min() and max() now support key= arguments with the same meaning as in
2314 list.sort().
2315
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002316- The peephole optimizer now performs simple constant folding in expressions:
2317 (2+3) --> (5).
2318
Raymond Hettingera422c342005-01-11 03:03:27 +00002319- set and frozenset objects can now be marshalled. SF #1098985.
2320
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002321- Bug #1077106: Poor argument checking could cause memory corruption

Jeremy Hyltonab630502005-02-04 18:44:06 +00002324- The parser did not complain about future statements in illegal
2325 positions. It once again reports a syntax error if a future
2326 statement occurs after anything other than a doc string.
2327
Neil Schemenauercf52c072005-08-12 17:34:58 +00002328- Change the %s format specifier for str objects so that it returns a
2329 unicode instance if the argument is not an instance of basestring and
2330 calling __str__ on the argument returns a unicode instance.
2331
Tim Petersf4e69282006-02-27 17:15:31 +00002332- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2333 current thread state when the auto-GIL-state machinery knows about
2334 it (since the thread state is being deleted, continuing to remember it
2335 can't help, but can hurt if another thread happens to get created with
2336 the same thread id).

2469 the request code argument, which results in more C-like behaviour
2470 for large or negative values.
2471
Tim Petersecc6e6a2005-07-10 22:30:55 +00002472- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

2487
Raymond Hettinger984f9bb2005-03-09 16:38:48 +00002488- operator.itemgetter() and operator.attrgetter() now support retrieving

2511
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002512- the cPickle module no longer accepts the deprecated None option in the
2513 args tuple returned by __reduce__().
2514
Raymond Hettingerb2594052004-12-05 09:25:51 +00002515- itertools.islice() now accepts None for the start and step arguments.
2516 This allows islice() to work more readily with slices:
2517 islice(s.start, s.stop, s.step)
2518
Skip Montanaro0af3ade2005-01-13 04:12:31 +00002519- datetime.datetime() now has a strptime class method which can be used to

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002528- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2529 been renamed to have only a single underscore prefix. This was done to
2530 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002531
Nick Coghlan43832302006-04-23 17:04:07 +00002532- PEP 338: new module runpy defines a run_module function to support
2533 executing modules which provide access to source code or a code object
2534 via the PEP 302 import mechanisms.
2535
Anthony Baxter93f5b932006-04-03 08:05:07 +00002536- The email module's parsedate_tz function now sets the daylight savings

2544 in attribute values.
2545
Anthony Baxterc51ee692006-04-01 00:57:31 +00002546- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002547 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002548 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002549 module will not be built.
2550
Tim Petersc17976e2006-04-01 00:26:53 +00002551- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2552 aren't officially supported here, and trying to use them will probably
2553 raise an exception some day. But dicts have been allowed, and "mostly
2554 worked", so support for them won't go away without warning.
2555
Georg Brandl338ef7d2006-03-31 18:42:16 +00002556- Bug #1445068: getpass.getpass() can now be given an explicit stream
2557 argument to specify where to write the prompt.
2558
Georg Brandl22ec80b2006-03-31 18:25:44 +00002559- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2574
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002575- email 4.0 package now integrated. This is largely the same as the email 3.0
2576 package that was included in Python 2.3, except that PEP 8 module names are
2577 now used (e.g. mail.message instead of email.Message). The MIME classes
2578 have been moved to a subpackage (e.g. email.mime.text instead of
2579 email.MIMEText). The old names are still supported for now. Several
2580 deprecated Message methods have been removed and lots of bugs have been
2581 fixed. More details can be found in the email package documentation.
2582
Walter Dörwald40108c92006-03-27 08:15:44 +00002583- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2584 (a subclass of tuple) that provides incremental decoders and encoders
2585 (a way to use stateful codecs without the stream API). Python functions
2586 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2587 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2588 have been added.

2671
2672 "The consensus of researchers in this area (at least as
2673 expressed at the NIST Hash Function Workshop 10/31/05),
2674 is that SHA-256 is a good choice for the time being, but
2675 that research should continue, and other alternatives may
2676 arise from this research. The larger SHA's also seem OK."

Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002849
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002850- Bug #1110478: Revert os.environ.update to do putenv again.
2851
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002852- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2853
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002854- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2855
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002856- Enhancements to the csv module:
2857
2858 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002859 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002860 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002861 + Dialect parameter parsing has been re-implemented to improve error
2862 reporting.
2863 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2864 dictates.
2865 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002866 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002867 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002868 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2869 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002870 + reader now allows \r characters to be quoted (previously it only allowed
2871 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002872 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002873 + Dialect classes passed to the module are no longer instantiated by
2874 the module before being parsed (the former validation scheme required
2875 this, but the mechanism was unreliable).
2876 + The dialect registry now contains instances of the internal
2877 C-coded dialect type, rather than references to python objects.
2878 + the internal c-coded dialect type is now immutable.
2879 + register_dialect now accepts the same keyword dialect specifications
2880 as the reader and writer, allowing the user to register dialects
2881 without first creating a dialect class.
2882 + a configurable limit to the size of parsed fields has been added -
2883 previously, an unmatched quote character could result in the entire
2884 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002885 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002886 the parser field size limit (returning the former limit). The initial
2887 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002888 + A line_num attribute has been added to the reader object, which tracks
2889 the number of lines read from the source iterator. This is not
2890 the same as the number of records returned, as records can span
2891 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002892 + reader and writer objects were not being registered with the cyclic-GC.
2893 This has been fixed.
2894
Brett Cannone6539c42005-01-08 02:43:53 +00002895- _DummyThread objects in the threading module now delete self.__block that is
2896 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2897 lock primitives tend to be limited in number and thus should not be wasted on
2898 a _DummyThread object. Fixes bug #1089632.
2899
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002900- The imghdr module now detects Exif files.
2901
Raymond Hettinger6065d322004-12-20 23:51:53 +00002902- StringIO.truncate() now correctly adjusts the size attribute.
2903 (Bug #951915).
2904
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002905- locale.py now uses an updated locale alias table (built using
2906 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2907 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002908 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002909
Raymond Hettinger3557f422004-12-07 12:02:02 +00002910- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2911
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002912- the pickle module no longer accepts the deprecated None option in the
2913 args tuple returned by __reduce__().
2914
Brett Cannon84667c02004-12-07 03:25:18 +00002915- optparse now optionally imports gettext. This allows its use in setup.py.
2916
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002917- the pickle module no longer uses the deprecated bin parameter.
2918
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002919- the shelve module no longer uses the deprecated binary parameter.
2920
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002921- the pstats module no longer uses the deprecated ignore() method.
2922
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002923- the filecmp module no longer uses the deprecated use_statcache argument.
2924
Raymond Hettinger664347b2004-12-04 21:21:53 +00002925- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2926 extended or overridden by subclasses. Formerly, the subclassed method would
2927 be ignored by the rest of the module. (Bug #1078905).
2928
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002929- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002930 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002931
Walter Dörwald36733692004-12-22 12:50:50 +00002932- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2933 once when a size argument is given. This prevents a buffer overflow in the
2934 tokenizer with very long source lines.
2935
Barry Warsaw538561e2006-01-01 21:48:54 +00002936- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2937 immediately after creating the object, without any intervening
2938 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002939
Skip Montanaro05885812005-01-16 20:48:27 +00002940- The reconvert.quote function can now emit triple-quoted strings. The
2941 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002942
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002943- ``UserString.MutableString`` now supports negative indices in
2944 ``__setitem__`` and ``__delitem__``
2945
Greg Ward40407942005-03-05 02:53:17 +00002946- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2947 correctly.
2948
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002949- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2950 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2951 character even if the user has passed a size parameter to get a proper
2952 line ending. Remove the special handling of a "\r\n" that has been split
2953 between two lines.
2954
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002955- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2956 about illegal code points. The codec now supports PEP 293 style error
2957 handlers.
2958
Walter Dörwald78a78b02005-09-01 12:04:29 +00002959- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00002960 from the input stream, so that the output is a byte string in the correct
2961 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00002962
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002963- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
2964 considering it exactly like a '*'.
2965
Walter Dörwald007f8df2005-10-09 19:42:27 +00002966- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
2967 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00002968
Walter Dörwald09f0dd52005-11-21 19:10:07 +00002969- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
2970
Gustavo Niemeyer548148812006-01-31 18:34:13 +00002971- Patch #1413711: Certain patterns of differences were making difflib
2972 touch the recursion limit.
2973
Walter Dörwald58917a62006-03-31 15:26:22 +00002974- Bug #947906: An object oriented interface has been added to the calendar
2975 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00002976 called as a script (e.g. via ``python -mcalendar``). Localized month and
2977 weekday names can be ouput (even if an exotic encoding is used) using
2978 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00002979
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002980Build
2981-----
2982
Neal Norwitz602d3392006-03-31 08:21:40 +00002983- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
2984 by using -mieee gcc option.
2985
Martin v. Löwis86d66262006-02-17 08:40:11 +00002986- Patch #1432345: Make python compile on DragonFly.
2987
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00002988- Build support for Win64-AMD64 was added.
2989
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00002990- Patch #1428494: Prefer linking against ncursesw over ncurses library.
2991
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00002992- Patch #881820: look for openpty and forkpty also in libbsd.
2993
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00002994- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
2995 The zlib module is now builtin on Windows.
2996
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00002997- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
2998
Martin v. Löwis147fbe52005-08-07 21:09:30 +00002999- Bug #1189330: configure did not correctly determine the necessary
3000 value of LINKCC if python was built with GCC 4.0.
3001
Trent Mick8321b422005-07-26 02:29:21 +00003002- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3003 vulnerability in zlib 1.2.1 and 1.2.2.
3004
Brett Cannon08cd5982005-04-24 22:26:38 +00003005- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3006 flags that change binary compatibility. Changes were also made to
3007 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003008 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003009
Bob Ippolitoed233462005-03-29 13:47:59 +00003010- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3011 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3012 no longer exists). This configure patch makes things right.
3013
Martin v. Löwise2713be2005-03-08 15:03:08 +00003014- Bug #1158607: Build with --disable-unicode again.
3015
Brett Cannon46d96232005-02-16 00:07:19 +00003016- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3017 defined. Discovered as a result of not being able to build on OS X.
3018
Brett Cannon516592f2004-12-07 00:42:59 +00003019- setup.py now uses the directories specified in LDFLAGS using the -L option
3020 and in CPPFLAGS using the -I option for adding library and include
3021 directories, respectively, for compiling extension modules against. This has
3022 led to the core being compiled using the values in CPPFLAGS. It also removes
3023 the need for the special-casing of both DarwinPorts and Fink for darwin since
3024 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3025 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3026 Fink, ``-I/opt/local/include`` for DarwinPorts).
3027
Brett Cannon43802422005-02-10 20:48:03 +00003028- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3029 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3030 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3031 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003033C API
3034-----
3035
Tim Petersc9d78aa2006-03-26 23:27:58 +00003036- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3037 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3038 is obtained via the ``PyObject_`` family, it must be released via the
3039 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3040 always been officially true, but when Python's small-object allocator was
3041 introduced, an attempt was made to cater to a few extension modules
3042 discovered at the time that obtained memory via ``PyObject_New`` but
3043 released it via ``PyMem_DEL``. It's years later, and if such code still
3044 exists it will fail now (probably with segfaults, but calling wrong
3045 low-level memory management functions can yield many symptoms).
3046
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003047- Added a C API for set and frozenset objects.
3048
Raymond Hettinger66517482004-12-03 11:45:13 +00003049- Removed PyRange_New().
3050
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003051- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3052 mapping argument now. This string is used as a mapping table. Byte values
3053 greater than the length of the string and 0xFFFE are treated as undefined
3054 mappings.
