Brett Cannon19d76c52006-09-09 07:18:44 +0000901- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
902 allows calling unicode() on exceptions classes directly to succeed.
903
Georg Brandlecab6232006-09-06 06:47:02 +0000904- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
905 Also make sure that every exception class has __module__ set to
906 'exceptions'.
907
Georg Brandl37a9e572006-09-06 06:09:34 +0000908- Bug #1550983: emit better error messages for erroneous relative

Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000919- The return tuple from str.rpartition(sep) is (tail, sep, head) where
920 head is the original string if sep was not found.
921
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000922- Bug #1520864: unpacking singleton tuples in list comprehensions and
923 generator expressions (x for x, in ... ) works again. Fixing this problem
924 required changing the .pyc magic number. This means that .pyc files
925 generated before 2.5c2 will be regenerated.

1037Core and builtins
1038-----------------
1039
Neal Norwitz24b6f202006-09-05 04:43:56 +00001040- Fix infinite recursion when subclassing long and overriding __hash__.
1041
1042- Fix concatenation (+=) of long strings.
1043
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001044- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001045 compared equal or unequal to a string and a UnicodeDecodeError
1046 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001047
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001048 Instead, the equal (==) and unequal (!=) comparison operators will
1049 now issue a UnicodeWarning and interpret the two objects as
1050 unequal. The UnicodeWarning can be filtered as desired using
1051 the warning framework, e.g. silenced completely, turned into an
1052 exception, logged, etc.
1053
1054 Note that compare operators other than equal and unequal will still
1055 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001056
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001057- Fix segfault when doing string formatting on subclasses of long.
1058
1059- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1060 with new-style classes.
1061
1062- Fix bug related to __len__ functions returning negative values with
1063 classic classes.
1064
1065- Patch #1538606, Fix __index__() clipping. There were some problems
1066 discovered with the API and how integers that didn't fit into Py_ssize_t
1067 were handled. This patch attempts to provide enough alternatives
1068 to effectively use __index__.
1069
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001070- Bug #1536021: __hash__ may now return long int; the final hash
1071 value is obtained by invoking hash on the long int.
1072
Thomas Hellerab1049c2006-08-08 17:37:00 +00001073- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1074
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001075- Bug #1535165: fixed a segfault in input() and raw_input() when
1076 sys.stdin is closed.
1077
Thomas Heller74d36f02006-08-04 18:17:40 +00001078- On Windows, the PyErr_Warn function is now exported from
1079 the Python dll again.
1080
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001081- Bug #1191458: tracing over for loops now produces a line event
1082 on each iteration. Fixing this problem required changing the .pyc
1083 magic number. This means that .pyc files generated before 2.5c1
1084 will be regenerated.
1085
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001086- Bug #1333982: string/number constants were inappropriately stored
1087 in the byte code and co_consts even if they were not used, ie
1088 immediately popped off the stack.
1089
Georg Brandle9462c72006-08-04 18:03:37 +00001090- Fixed a reference-counting problem in property().

1093Library
1094-------
1095
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001096- Fix a bug in the ``compiler`` package that caused invalid code to be
1097 generated for generator expressions.
1098
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001099- The distutils version has been changed to 2.5.0. The change to
1100 keep it programmatically in sync with the Python version running
1101 the code (introduced in 2.5b3) has been reverted. It will continue
1102 to be maintained manually as static string literal.
1103
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001104- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001105 and this cannot be converted to the required C type, an exception is
1106 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001107 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001108
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001109- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001110 an exception.
1111
Tim Peterscbdd3502006-09-05 01:47:53 +00001112- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001113 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001114 workarounds for clocks with low resolution, to stop the code yielding
1115 duplicate UUIDs.
1116
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001117- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1118 before raising SystemExit, allowing IDLE to honor quit() and exit().
1119
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001120- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1121
Georg Brandl7a1af772006-08-14 21:55:28 +00001122- Patch #1536071: trace.py should now find the full module name of a
1123 file correctly even on Windows.
1124
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001125- logging's atexit hook now runs even if the rest of the module has
1126 already been cleaned up.
1127
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001128- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001129
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001130- Bug #1531405, format_exception no longer raises an exception if
1131 str(exception) raised an exception.
1132
Neil Schemenauer06ded092006-08-04 16:20:30 +00001133- Fix a bug in the ``compiler`` package that caused invalid code to be
1134 generated for nested functions.

1151 uses the _as_parameter_ attribute when objects are passed to foreign
1152 function calls. The ctypes version number was changed to 1.0.1.
1153
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001154- Bug #1530559, struct.pack raises TypeError where it used to convert.
1155 Passing float arguments to struct.pack when integers are expected
1156 now triggers a DeprecationWarning.

Fred Drake53912162006-07-29 13:22:49 +00001201What's New in Python 2.5 beta 3?
1202================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001203
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001204*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001205
1206Core and builtins
1207-----------------
1208
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001209- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001210 returned a long (see PEP 353).
1211
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001212- Bug #1515471: string.replace() accepts character buffers again.
1213
Neal Norwitz07aadb12006-07-30 06:55:48 +00001214- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1215 This provides the proper warning for struct.pack().
1216 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1217
Neal Norwitz0d62a062006-07-30 06:53:31 +00001218- Patch #1531113: Fix augmented assignment with yield expressions.
1219 Also fix a SystemError when trying to assign to yield expressions.
1220
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001221- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1222 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1223 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1224 excessive filesystem operations during imports.
1225
Tim Petersbc24eee2006-07-27 01:14:53 +00001226- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1227 operations on signed longs that are formally undefined by C.
1228 Unfortunately, at least one compiler now cares about that, so complicated
1229 the code to make that compiler happy again.
1230
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001231- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1232
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001233- Patch #1232023: Stop including current directory in search
1234 path on Windows.
1235
Neal Norwitze1fdb322006-07-21 05:32:28 +00001236- Fix some potential crashes found with failmalloc.
1237
Neal Norwitze7563102006-07-17 01:00:16 +00001238- Fix warnings reported by Klocwork's static analysis tool.
1239
Neal Norwitz84be93b2006-07-16 01:50:38 +00001240- Bug #1512814, Fix incorrect lineno's when code within a function
1241 had more than 255 blank lines.
1242
Georg Brandl9dceedb2006-07-12 15:31:17 +00001243- Patch #1521179: Python now accepts the standard options ``--help`` and
1244 ``--version`` as well as ``/?`` on Windows.
1245
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001246- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001247 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001248 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001249
Tim Peters112aad32006-07-19 00:03:19 +00001250- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001251 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001252 new ``sys._current_frames()`` returns a dictionary with one entry,
1253 mapping the faux "thread id" 0 to the current frame.
1254
Ronald Oussoren3075e162006-07-25 20:28:55 +00001255- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001256
Ronald Oussoren3075e162006-07-25 20:28:55 +00001257
Neal Norwitza1f10902006-07-12 07:28:29 +00001258Library
1259-------
1260
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001261- Correction of patch #1455898: In the mbcs decoder, set final=False
1262 for stream decoder, but final=True for the decode function.
1263
Georg Brandl07fec3a2006-08-01 18:49:24 +00001264- os.urandom no longer masks unrelated exceptions like SystemExit or
1265 KeyboardInterrupt.
1266
Tim Peters4643c2f2006-08-10 22:45:34 +00001267- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001268 shutil.copytree on Windows
1269
Georg Brandle34ac7c2006-07-30 11:07:23 +00001270- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1271 refers to file descriptors, not file objects.
1272
Tim Peterscbdd3502006-09-05 01:47:53 +00001273- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001274 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001275 #1513611, and probably others.
1276
Georg Brandledd9b0d2006-07-29 09:33:26 +00001277- Bug #1441397: The compiler module now recognizes module and function
1278 docstrings correctly as it did in Python 2.4.
1279
Tim Peters6f681472006-07-27 23:44:37 +00001280- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1281 lost that tests are sorted by name before being run. This rarely
1282 matters for well-written tests, but can create baffling symptoms if
1283 side effects from one test to the next affect outcomes. ``DocTestFinder``
1284 has been changed to sort the list of tests it returns.
1285
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001286- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001287 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001288
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001289- Bug #978833: Really close underlying socket in _socketobject.close.
1290
Georg Brandldb232dc2006-08-20 13:15:43 +00001291- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1292 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001293
Georg Brandlcf0c1722006-07-26 07:23:32 +00001294- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1295 to recursive calls and call it with the failing package name.
1296
Martin v. Löwis0b483032006-07-25 09:53:12 +00001297- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1298
Georg Brandlc13c34c2006-07-24 14:09:56 +00001299- Patch #1515343: Fix printing of deprecated string exceptions with a
1300 value in the traceback module.
1301
Greg Ward48fae7a2006-07-23 16:05:51 +00001302- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1303
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001304- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1305
Brett Cannoncaebe222006-07-18 04:41:36 +00001306- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1307 argument tuple. For arguments where zero is illegal, the value is forced to
1308 the minimum value that is correct. This is to support an undocumented but
1309 common way people used to fill in inconsequential information in the time
1310 tuple pre-2.4.
1311
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001312- Patch #1220874: Update the binhex module for Mach-O.
1313
Barry Warsawb110bad2006-07-21 14:51:07 +00001314- The email package has improved RFC 2231 support, specifically for
1315 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1316 (name*0=<blah>) parameter continuations. This may change the types of
1317 values returned from email.message.Message.get_param() and friends.
1318 Specifically in some cases where non-encoded continuations were used,
1319 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1320 will just return the string (since non-encoded continuations don't have
1321 charset and language parts).
1322
1323 Also, whereas % values were decoded in all parameter continuations, they are
1324 now only decoded in encoded parameter parts.
1325
Ronald Oussoren3075e162006-07-25 20:28:55 +00001326- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1327
1328- Bug #1517996: IDLE now longer shows the default Tk menu when a
1329 path browser, class browser or debugger is the frontmost window on MacOS X
1330
Barry Warsaw00decd72006-07-27 23:43:15 +00001331- Patch #1520294: Support for getset and member descriptors in types.py,
1332 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1333 of an object against these built-in types and more importantly, for getting
1334 their docstrings printed in the interactive interpreter's help() function.
1335
Ronald Oussoren3075e162006-07-25 20:28:55 +00001336
Neal Norwitza1f10902006-07-12 07:28:29 +00001337Extension Modules
1338-----------------
1339
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001340- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1341 a socket operation on a socket with a timeout, the exception will be
1342 caught correctly. Previously, the exception was not caught.
1343
Thomas Heller1393d6a2006-07-28 21:43:20 +00001344- Patch #1529514: The _ctypes extension is now compiled on more
1345 openbsd target platforms.
1346
Tim Peters9cab5932006-07-28 00:30:00 +00001347- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1348 a memory leak, affecting pickles and deep copies.
1349
Tim Petersbc24eee2006-07-27 01:14:53 +00001350- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001351 Paul Eggert.
1352
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001353- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1354
Thomas Hellerce049a02006-07-14 17:51:14 +00001355- Patch #1521817: Index range checking on ctypes arrays containing
1356 exactly one element enabled again. This allows iterating over these
1357 arrays, without the need to check the array size before.
1358
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001359- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001360 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001361 /dev/null in certain cases; this is now fixed.
1362
Thomas Heller47d7a062006-07-12 08:43:47 +00001363- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1364 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001365
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001366- Because of a misspelled preprocessor symbol, ctypes was always
1367 compiled without thread support; this is now fixed.
1368
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001369- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1370 methods now allow their database parameter to be None as the
1371 sleepycat API allows.
1372
Matt Flemingec926502006-07-28 11:27:27 +00001373- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1374 bluetooth API compared with Linux and FreeBSD.
1375
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001376Tests
1377-----
1378
1379- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1380 how long the test file should take to play. Now accepts taking 2.93 secs
1381 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1382
Georg Brandl4793aa32006-07-28 18:31:39 +00001383- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1384 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1385 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +00001386
Martin v. Löwis0907f4d2006-07-30 14:09:47 +00001387Build

Ronald Oussoren26cad082006-08-01 21:00:57 +00001392Mac
1393---
1394
1395- PythonLauncher now works correctly when the path to the script contains
1396 characters that are treated specially by the shell (such as quotes).
1397
1398- Bug #1527397: PythonLauncher now launches scripts with the working directory
1399 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001400 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001401 expect.

1410-----------------
1411
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001412- Bug #1441486: The literal representation of -(sys.maxint - 1)
1413 again evaluates to a int object, not a long.
1414
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001415- Bug #1501934: The scope of global variables that are locally assigned
1416 using augmented assignment is now correctly determined.
1417
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001418- Bug #927248: Recursive method-wrapper objects can now safely
1419 be released.
1420
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001421- Bug #1417699: Reject locale-specific decimal point in float()
1422 and atof().
1423
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001424- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1425 omit a default "error" argument for NULL pointer. This allows
1426 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001427
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001428- Bug #1519018: 'as' is now validated properly in import statements.
1429
Neal Norwitz28746ab2006-07-09 22:14:42 +00001430- On 64 bit systems, int literals that use less than 64 bits are
1431 now ints rather than longs.
1432
Neal Norwitzed657552006-07-10 00:04:44 +00001433- Bug #1512814, Fix incorrect lineno's when code at module scope
1434 started after line 256.
1435
Tim Peters32a83612006-07-10 21:08:24 +00001436- New function ``sys._current_frames()`` returns a dict mapping thread
1437 id to topmost thread stack frame. This is for expert use, and is
1438 especially useful for debugging application deadlocks. The functionality
1439 was previously available in Fazal Majid's ``threadframe`` extension
1440 module, but it wasn't possible to do this in a wholly threadsafe way from
1441 an extension.

Martin v. Löwis77621582006-07-30 13:27:31 +00001446- Bug #1257728: Mention Cygwin in distutils error message about a missing
1447 VS 2003.
1448
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001449- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1450
Tim Peters32a83612006-07-10 21:08:24 +00001451- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001452 environment variable to be set in order to the SDK environment
1453 for finding the compiler, include files, etc.

Martin v. Löwis388a8c22006-07-06 19:28:03 +00001455- Bug #1515998: Properly generate logical ids for files in bdist_msi.
1456
Nick Coghlan2d792252006-07-06 13:47:18 +00001457- warnings.py now ignores ImportWarning by default
1458
Thomas Woutersadd19112006-07-05 11:03:49 +00001459- string.Template() now correctly handles tuple-values. Previously,
1460 multi-value tuples would raise an exception and single-value tuples would
1461 be treated as the value they contain, instead.
1462
Martin v. Löwisede77f52006-07-03 13:01:35 +00001463- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1464 even if some data are received.
1465
Martin v. Löwis45482392006-07-03 12:28:58 +00001466- Bug #1267547: Put proper recursive setup.py call into the
1467 spec file generated by bdist_rpm.
1468
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001469- Bug #1514693: Update turtle's heading when switching between
1470 degrees and radians.
1471
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001472- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001473 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001474
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001475- Bug #1514703: Only setup canvas window in turtle when the canvas
1476 is created.

Martin v. Löwis7596e832006-07-01 15:33:37 +00001478- Bug #1513223: .close() of a _socketobj now releases the underlying
1479 socket again, which then gets closed as it becomes unreferenced.
1480
Fred Drake10497c82006-06-29 02:57:48 +00001481- Bug #1504333: Make sgmllib support angle brackets in quoted
1482 attribute values.
1483
1484- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1485 sgmllib ('[' and ']' were not accepted).
1486
Georg Brandl1be63af2006-06-28 20:23:25 +00001487- Fix a bug in the turtle module's end_fill function.
1488
Brett Cannon53ab5b72006-06-22 16:49:14 +00001489- Bug #1510580: The 'warnings' module improperly required that a Warning
1490 category be either a types.ClassType and a subclass of Warning. The proper
1491 check is just that it is a subclass with Warning as the documentation states.
1492
Georg Brandlad29e632006-06-21 17:45:17 +00001493- The compiler module now correctly compiles the new try-except-finally
1494 statement (bug #1509132).
1495
Neal Norwitz60373cd2006-06-22 06:30:50 +00001496- The wsgiref package is now installed properly on Unix.
1497
Vinay Sajip28e57612006-07-01 10:45:20 +00001498- A bug was fixed in logging.config.fileConfig() which caused a crash on
1499 shutdown when fileConfig() was called multiple times.
1500
Gerhard Häring762fbd32006-07-02 17:48:30 +00001501- The sqlite3 module did cut off data from the SQLite database at the first
1502 null character before sending it to a custom converter. This has been fixed
1503 now.
1504
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001505Extension Modules
1506-----------------
1507
Tim Peters112aad32006-07-19 00:03:19 +00001508- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1509 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1510 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001511
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001512- Assigning None to pointer type fields in ctypes structures possible
1513 overwrote the wrong fields, this is fixed now.
1514
1515- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1516 on non-Windows platforms.
1517
1518- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1519 integer or long, without range checking.
1520
1521- Patch #1517790: It is now possible to use custom objects in the ctypes
1522 foreign function argtypes sequence as long as they provide a from_param
1523 method, no longer is it required that the object is a ctypes type.
1524
1525- The '_ctypes' extension module now works when Python is configured
1526 with the --without-threads option.
1527
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001528- Bug #1513646: os.access on Windows now correctly determines write
1529 access, again.
1530
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001531- Bug #1512695: cPickle.loads could crash if it was interrupted with
1532 a KeyboardInterrupt.
1533
Neal Norwitza12aa882006-07-06 06:45:08 +00001534- Bug #1296433: parsing XML with a non-default encoding and
1535 a CharacterDataHandler could crash the interpreter in pyexpat.
1536
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001537- Patch #1516912: improve Modules support for OpenVMS.
1538

1540-----
1541
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001542- Automate Windows build process for the Win64 SSL module.
1543
Tim Peters32a83612006-07-10 21:08:24 +00001544- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001545 Previously, the slight difference could cause compilation errors of the
1546 'zlib' module on systems with more than one version of zlib.
1547
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001548- The MSI compileall step was fixed to also support a TARGETDIR
1549 with spaces in it.
1550
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001551- Bug #1517388: sqlite3.dll is now installed on Windows independent
1552 of Tcl/Tk.
1553
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001554- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001555 trying to be installed even though it's empty.

Neal Norwitzb15ac312006-06-29 04:10:08 +00001557Tests
1558-----
1559
1560- Call os.waitpid() at the end of tests that spawn child processes in order
1561 to minimize resources (zombies).
1562
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001563Documentation
1564-------------
1565
Nick Coghlan2d792252006-07-06 13:47:18 +00001566- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1567 documentation for the warnings module.
1568
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001569- Patch #1509163: MS Toolkit Compiler no longer available.
1570
Neal Norwitz56640df2006-07-10 02:36:41 +00001571- Patch #1504046: Add documentation for xml.etree.

Georg Brandl212b5872006-08-05 06:10:54 +00001573
Nick Coghlanc649ec52006-05-29 12:43:05 +00001574What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +00001575================================
Anthony Baxter51bcb682006-04-05 14:51:42 +00001576

Anthony Baxter51bcb682006-04-05 14:51:42 +00001578
1579Core and builtins
1580-----------------
1581
Georg Brandla56b9152006-06-19 06:35:54 +00001582- Patch #1507676: Error messages returned by invalid abstract object operations
1583 (such as iterating over an integer) have been improved and now include the
1584 type of the offending object to help with debugging.
1585
Brett Cannonea3912b2006-06-13 21:46:41 +00001586- Bug #992017: A classic class that defined a __coerce__() method that returned
1587 its arguments swapped would infinitely recurse and segfault the interpreter.
1588
Neal Norwitz909eb122006-06-12 02:13:21 +00001589- Fix the socket tests so they can be run concurrently.
1590
Neal Norwitzb9845e72006-06-12 02:11:18 +00001591- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001592 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001593
Brett Cannon22565aa2006-06-09 22:31:23 +00001594- Bug #532646: object.__call__() will continue looking for the __call__
1595 attribute on objects until one without one is found. This leads to recursion
1596 when you take a class and set its __call__ attribute to an instance of the
1597 class. Originally fixed for classic classes, but this fix is for new-style.
1598 Removes the infinite_rec_3 crasher.
1599
Georg Brandl24250812006-06-09 18:45:48 +00001600- The string and unicode methods startswith() and endswith() now accept
1601 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1602
Brett Cannonde3b0522006-06-08 17:00:45 +00001603- Buffer objects, at the C level, never used the char buffer
1604 implementation even when the char buffer for the wrapped object was
1605 explicitly requested (originally returned the read or write buffer).
1606 Now a TypeError is raised if the char buffer is not present but is
1607 requested.
1608
Georg Brandlddbaa662006-06-04 21:56:52 +00001609- Patch #1346214: Statements like "if 0: suite" are now again optimized
1610 away like they were in Python 2.4.
1611
Georg Brandlb7c8f542006-05-27 12:30:25 +00001612- Builtin exceptions are now full-blown new-style classes instead of
1613 instances pretending to be classes, which speeds up exception handling
1614 by about 80% in comparison to 2.5a2.
1615
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001616- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1617 Unicode 4.1.
1618
Georg Brandlf4ef1162006-05-26 18:03:31 +00001619- Patch #921466: sys.path_importer_cache is now used to cache valid and
1620 invalid file paths for the built-in import machinery which leads to
1621 fewer open calls on startup.
1622
Tim Peters696cf432006-05-24 21:10:40 +00001623- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1624 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1625 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1626 the number of input digits (it was and remains linear-time for bases
1627 2, 4, 8, 16 and 32).
1628
Tim Petersb713ec22006-05-23 18:45:30 +00001629- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1630 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1631 an integer close to ``sys.maxint``. This was repaired by patch
1632 #1335972, which also gives a nice speedup.
1633
Richard Jonescebbefc2006-05-23 18:28:17 +00001634- Patch #1337051: reduced size of frame objects.
1635
1636- PyErr_NewException now accepts a tuple of base classes as its
1637 "base" parameter.
1638
Richard Jones7c88dcc2006-05-23 10:37:38 +00001639- Patch #876206: function call speedup by retaining allocated frame
1640 objects.
1641
Georg Brandl7b90e162006-05-18 07:01:27 +00001642- Bug #1462152: file() now checks more thoroughly for invalid mode
1643 strings and removes a possible "U" before passing the mode to the
1644 C library function.
1645
Neal Norwitz1004a532006-05-15 07:17:23 +00001646- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1647
Neal Norwitz373f0a72006-05-15 07:04:36 +00001648- Bug #1487966: Fix SystemError with conditional expression in assignment
1649
Martin v. Löwis879768d2006-05-11 13:28:43 +00001650- WindowsError now has two error code attributes: errno, which carries
1651 the error values from errno.h, and winerror, which carries the error
1652 values from winerror.h. Previous versions put the winerror.h values
1653 (from GetLastError()) into the errno attribute.
1654
Martin v. Löwis77736712006-05-04 05:51:03 +00001655- Patch #1475845: Raise IndentationError for unexpected indent.
1656
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001657- Patch #1479181: split open() and file() from being aliases for each other.
1658
Tim Peters44bd9862006-06-01 13:49:23 +00001659- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1660 methods were always silently ignored by dictionaries when comparing keys.
1661 They are now passed through (except when using the C API function
1662 ``PyDict_GetItem()``, whose semantics did not change).
1663
1664- Bug #1456209: In some obscure cases it was possible for a class with a
1665 custom ``__eq__()`` method to confuse dict internals when class instances
1666 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1667 No, you don't have any code that did this ;-)

1670-----------------
1671
Trent Mick960a3f82006-06-28 20:30:41 +00001672- Bug #1295808: expat symbols should be namespaced in pyexpat
1673
1674- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1675
Brett Cannon6ee7d012006-06-08 16:23:04 +00001676- Change binascii.hexlify to accept a read-only buffer instead of only a char
1677 buffer and actually follow its documentation.
1678
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001679- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1680
Nick Coghlanc649ec52006-05-29 12:43:05 +00001681- Patch #1478788 (modified version): The functional extension module has
1682 been renamed to _functools and a functools Python wrapper module added.
1683 This provides a home for additional function related utilities that are
1684 not specifically about functional programming. See PEP 309.
1685
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001686- Patch #1493701: performance enhancements for struct module.
1687
Georg Brandl378d5922006-05-17 14:26:50 +00001688- Patch #1490224: time.altzone is now set correctly on Cygwin.
1689
Georg Brandl8d3342b2006-05-16 07:38:27 +00001690- Patch #1435422: zlib's compress and decompress objects now have a
1691 copy() method.
1692
Andrew MacIntyre92913322006-06-13 15:04:24 +00001693- Patch #1454481: thread stack size is now tunable at runtime for thread
1694 enabled builds on Windows and systems with Posix threads support.
1695
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001696- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1697 (up to the system limit of 32K characters).
1698
1699- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1700 As a result, these functions now raise WindowsError instead of OSError.
1701
Tim Peters7a822da2006-05-25 21:50:17 +00001702- ``time.clock()`` on Win64 should use the high-performance Windows
1703 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1704 Windows platforms).
1705
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001706- Calling Tk_Init twice is refused if the first call failed as that
1707 may deadlock.
1708
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001709- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1710 accept it without potentially using an uninitialized pointer.
1711
1712- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1713 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1714 patch numbers 1494885 and 1494902]

1718
Gregory P. Smith372b5832006-06-05 18:48:21 +00001719- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1720 parameter is supplied. [SF pybsddb bug #1477863]
1721
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001722- bsddb: the __len__ method of a DB object has been fixed to return correct
1723 results. It could previously incorrectly return 0 in some cases.
1724 Fixes SF bug 1493322 (pybsddb bug 1184012).
1725
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001726- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1727 aborts the db transaction safely when a modifier callback fails.
1728 Fixes SF python patch/bug #1408584.
1729
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001730- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001731 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001732 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1733 database calls that would previously deadlock. [SF python bug #775414]
1734
Vinay Sajip28e57612006-07-01 10:45:20 +00001735- Patch #1446489: add support for the ZIP64 extensions to zipfile.

1750
Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00001751- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
1752
Martin v. Löwis337487e2006-06-17 09:15:14 +00001753- Patch #763580: Add name and value arguments to Tkinter variable
1754 classes.
1755
Georg Brandl83cc0d02006-06-14 08:50:03 +00001756- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
1757 mime.types file for determining MIME types.
1758
Georg Brandl2605ca82006-06-14 06:08:31 +00001759- Bug #1339007: Shelf objects now don't raise an exception in their
1760 __del__ method when initialization failed.
1761
Martin v. Löwisd8251432006-06-14 05:21:04 +00001762- Patch #1455898: The MBCS codec now supports the incremental mode for
1763 double-byte encodings.
1764
Tim Peters43898b42006-06-14 04:09:25 +00001765- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1766 guarantee that adjacent triples in the return list always describe
1767 non-adjacent blocks. Previously, a pair of matching blocks could end
1768 up being described by multiple adjacent triples that formed a partition

Greg Ward0e0c9f42006-06-11 16:24:11 +00001771- Bug #1498146: fix optparse to handle Unicode strings in option help,
1772 description, and epilog.
1773
Greg Wardd1c797e2006-06-11 14:42:41 +00001774- Bug #1366250: minor optparse documentation error.
1775
Greg Ward7f547402006-06-11 00:40:49 +00001776- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1777 clarify docs.
1778
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001779- The wsgiref package has been added to the standard library.
1780
Nick Coghlan676725d2006-06-08 13:54:49 +00001781- The functions update_wrapper() and wraps() have been added to the functools
1782 module. These make it easier to copy relevant metadata from the original
1783 function when writing wrapper functions.
1784
Tim Petersd6a9eef2006-06-05 01:48:21 +00001785- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1786 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001787
Martin v. Löwis3f767792006-06-04 19:36:28 +00001788- Patch #1359618: Speed up charmap encoder by using a trie structure
1789 for lookup.
1790
Tim Petersd609b1a2006-06-02 23:22:51 +00001791- The functions in the ``pprint`` module now sort dictionaries by key
1792 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1793 if and only if its display required more than one line, although that
1794 wasn't documented. The new behavior increases predictability; e.g.,
1795 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1796
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001797- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1798 (thanks for J. J. Lee).
1799
Georg Brandl2b330372006-05-28 20:23:12 +00001800- Patch #1496206: improve urllib2 handling of passwords with respect to
1801 default HTTP and HTTPS ports.
1802
George Yoshidaf3c65de2006-05-28 16:39:09 +00001803- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1804
Bob Ippolito7298f272006-05-23 18:43:47 +00001805- Patch #1281707: speed up gzip.readline.
1806
Georg Brandlb89316f2006-05-17 15:51:16 +00001807- Patch #1180296: Two new functions were added to the locale module:
1808 format_string() to get the effect of "format % items" but locale-aware,
1809 and currency() to format a monetary number with currency sign.
1810
Georg Brandle3a25832006-05-17 14:56:04 +00001811- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1812 and several features added, such as speed and geometry control.
1813
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001814- Patch #1488881: add support for external file objects in bz2 compressed
1815 tarfiles.
1816
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001817- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1818 stdout arguments, making it possible to redirect input and output
1819 for remote debugging.
1820
1821- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1822 a couple of issues, notably handling of long file names using the
1823 GNU LONGNAME extension.
1824
1825- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1826 new flag when ``name`` is already the name of an option flag.
1827
1828- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1829 package.
1830
1831- Patch #1472854: make the rlcompleter.Completer class usable on non-
1832 UNIX platforms.
1833
1834- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1835
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001836- Bug #1472827: correctly escape newlines and tabs in attribute values in
1837 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00001867What's New in Python 2.5 alpha 2?
1868=================================
1869
1870*Release date: 27-APR-2006*
1871
1872Core and builtins
1873-----------------
1874
Thomas Heller1b046642006-04-18 18:51:06 +00001875- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1876 by converting these apis from macros into exported functions again:
1877
1878 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1879 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1880 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1881 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1882 PyRun_String Py_CompileString
1883
Martin v. Löwis45294a92006-04-18 06:24:08 +00001884- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1885
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001886- All uses of PyStructSequence_InitType have been changed to initialize
1887 the type objects only once, even if the interpreter is initialized
1888 multiple times.
1889
Neal Norwitz61546162006-04-14 05:20:28 +00001890- Bug #1454485, array.array('u') could crash the interpreter. This was
1891 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1892 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1893
1894- Py_UNICODE is unsigned. It was always documented as unsigned, but
1895 due to a bug had a signed value in previous versions.
1896
Tim Peters3a5e8b12006-04-11 01:44:07 +00001897- Patch #837242: ``id()`` of any Python object always gives a positive
1898 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1899 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001900 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001901 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001902
Tim Peters3a5e8b12006-04-11 01:44:07 +00001903 def __hash__(self):
1904 return id(self) # WRONG
1905
1906 because a hash result must be a (short) Python int but it was always
1907 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001908 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001909 was always usable as a hash value before this patch. That's no longer
1910 necessarily so.
1911
1912- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001913 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001914 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001915 #1454844)
1916
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001917- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1918 involving generators that have paused outside of any ``try`` or ``with``
1919 blocks. (In 2.5a1, a paused generator that was part of a reference
1920 cycle could not be garbage collected, regardless of whether it was
1921 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00001922
Anthony Baxter51bcb682006-04-05 14:51:42 +00001923Extension Modules

1925
Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00001926- Patch #1191065: Fix preprocessor problems on systems where recvfrom
1927 is a macro.
1928
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001929- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1930 fails with an error condition.
1931
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001932- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1933
1934- Bug #1117761: bsddb.*open() no longer raises an exception when using
1935 the cachesize parameter.
1936
1937- Bug #1149413: bsddb.*open() no longer raises an exception when using
1938 a temporary db (file=None) with the 'n' flag to truncate on open.
1939
1940- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1941 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001942
Armin Rigoa9017c32006-04-19 11:50:27 +00001943- Patch #1062014: AF_UNIX sockets under Linux have a special
1944 abstract namespace that is now fully supported.

1948
Peter Astrand7d1d4362006-07-14 14:04:45 +00001949- Bug #1223937: subprocess.CalledProcessError reports the exit status
1950 of the process using the returncode attribute, instead of
1951 abusing errno.
1952
Tim Peters711bf302006-04-25 03:31:36 +00001953- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1954 a doctest to be skipped (the code is not run, and the expected output
1955 or exception is ignored).
1956
Nick Coghlanda2268f2006-04-24 04:37:15 +00001957- Fixed contextlib.nested to cope with exceptions being raised and
1958 caught inside exit handlers.
1959
Greg Wardab05edc2006-04-23 03:47:58 +00001960- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1961 hex, octal, or binary; add ``append_const`` action; keep going if
1962 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1963 added ``epilog`` for better help generation).
1964
Tim Peters21fbd572006-04-21 21:18:10 +00001965- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1966 called from a thread spawned as a side effect of importing a module.
1967
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001968- The pydoc module now supports documenting packages contained in
1969 .zip or .egg files.
1970
1971- The pkgutil module now has several new utility functions, such
1972 as ``walk_packages()`` to support working with packages that are either
1973 in the filesystem or zip files.
1974
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001975- The mailbox module can now modify and delete messages from
1976 mailboxes, in addition to simply reading them. Thanks to Gregory
1977 K. Johnson for writing the code, and to the 2005 Google Summer of
1978 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001979
Tim Petersc7605f22006-04-17 21:12:33 +00001980- The ``__del__`` method of class ``local`` in module ``_threading_local``
1981 returned before accomplishing any of its intended cleanup.
1982
Martin v. Löwisbd30f522006-04-17 17:08:37 +00001983- Patch #790710: Add breakpoint command lists in pdb.
1984

1988
Anthony Baxtere29002c2006-04-12 12:07:31 +00001989- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
1990 Windows. Bug #1469163.
1991
Phillip J. Eby47032112006-04-11 01:07:43 +00001992- The warnings, linecache, inspect, traceback, site, and doctest modules
1993 were updated to work correctly with modules imported from zipfiles or
1994 via other PEP 302 __loader__ objects.
1995
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00001996- Patch #1467770: Reduce usage of subprocess._active to processes which

2008
Martin v. Löwis4be4e652006-04-17 19:25:49 +00002009- The Makefile now has a reindent target, which runs reindent.py on
2010 the library.
2011
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002012- Patch #1470875: Building Python with MS Free Compiler

2017 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002018 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002019 CXX from --with-cxx-main, see description in README.
2020

Hye-Shik Changf4795c82006-04-26 19:20:26 +00002023- Fixed a libffi build problem on MIPS systems.
2024
Tim Peters8931ff12006-05-13 23:28:20 +00002025- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2026 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2027 and "%zu" for unsigned integers of type ``size_t``.
2028
Anthony Baxter51bcb682006-04-05 14:51:42 +00002029Tests
2030-----
2031
Nick Coghlanda2268f2006-04-24 04:37:15 +00002032- test_contextlib now checks contextlib.nested can cope with exceptions
2033 being raised and caught inside exit handlers.
2034
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002035- test_cmd_line now checks operation of the -m and -c command switches
2036
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002037- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2038 it separately and by hand. It also wasn't cleaning up its changes to
2039 the current Decimal context.
2040
Thomas Woutersabd08882006-04-26 15:53:30 +00002041- regrtest.py now has a -M option to run tests that test the new limits of
2042 containers, on 64-bit architectures. Running these tests is only sensible
2043 on 64-bit machines with more than two gigabytes of memory. The argument
2044 passed is the maximum amount of memory for the tests to use.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002065What's New in Python 2.5 alpha 1?
2066=================================
2067
Anthony Baxterebed3f62006-04-03 15:03:44 +00002068*Release date: 05-APR-2006*

2071-----------------
2072
Nick Coghlan43832302006-04-23 17:04:07 +00002073- PEP 338: -m command line switch now delegates to runpy.run_module
2074 allowing it to support modules in packages and zipfiles
2075
Martin v. Löwisc661b882006-04-20 04:54:23 +00002076- On Windows, .DLL is not an accepted file name extension for
2077 extension modules anymore; extensions are only found if they
2078 end in .PYD.
2079
Martin v. Löwisea62d252006-04-03 10:56:49 +00002080- Bug #1421664: sys.stderr.encoding is now set to the same value as
2081 sys.stdout.encoding.
2082
Neal Norwitz92e212f2006-04-03 04:48:37 +00002083- __import__ accepts keyword arguments.
2084
Georg Brandlccadf842006-03-31 18:54:53 +00002085- Patch #1460496: round() now accepts keyword arguments.
2086
Anthony Baxter262c00a2006-03-30 10:53:17 +00002087- Fixed bug #1459029 - unicode reprs were double-escaped.
2088
Hye-Shik Changd478f342006-03-23 12:32:36 +00002089- Patch #1396919: The system scope threads are reenabled on FreeBSD
2090 5.4 and later versions.
2091
Neal Norwitze98ccf62006-03-23 05:39:47 +00002092- Bug #1115379: Compiling a Unicode string with an encoding declaration
2093 now gives a SyntaxError.
2094
Georg Brandlabd1ff82006-03-18 07:59:59 +00002095- Previously, Python code had no easy way to access the contents of a
2096 cell object. Now, a ``cell_contents`` attribute has been added
2097 (closes patch #1170323).
2098
Tim Peterscf79aac2006-03-16 01:14:46 +00002099- Patch #1123430: Python's small-object allocator now returns an arena to
2100 the system ``free()`` when all memory within an arena becomes unused
2101 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2102 freed. Some applications will see a drop in virtual memory size now,
2103 especially long-running applications that, from time to time, temporarily
2104 use a large number of small objects. Note that when Python returns an
2105 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002106 platform C library will in turn return that memory to the operating system.
2107 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002108 appears to be effective at least on Microsoft C and gcc-based systems.
2109 Thanks to Evan Jones for hard work and patience.
2110
Georg Brandl533ff6f2006-03-08 18:09:27 +00002111- Patch #1434038: property() now uses the getter's docstring if there is
2112 no "doc" argument given. This makes it possible to legitimately use
2113 property() as a decorator to produce a read-only property.
2114
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002115- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2116 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2117 of requiring an int or long in slicing and a few other contexts, enabling
2118 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2119
Neal Norwitz995acdf2006-03-07 05:01:00 +00002120- Fixed various bugs reported by Coverity's Prevent tool.
2121
Brett Cannonbf364092006-03-01 04:25:17 +00002122- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2123 new exception base class, BaseException, which has a new message attribute.
2124 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2125 Raising a string exception now raises a DeprecationWarning.
2126
Thomas Woutersfb609f42006-02-28 16:37:25 +00002127- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2128 explicitly relative, using 'from .module import name' to mean 'from the same
2129 package as this module is in. Imports without dots still default to the
2130 old relative-then-absolute, unless 'from __future__ import
2131 absolute_import' is used.
2132
Brett Cannona7446e32006-02-27 23:39:10 +00002133- Properly check if 'warnings' raises an exception (usually when a filter set
2134 to "error" is triggered) when raising a warning for raising string
2135 exceptions.
2136
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002137- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002138 The name was removed from Include/code.h.
2139
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002140- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002141
Guido van Rossum1968ad32006-02-25 22:38:04 +00002142- Patch 1433928:
2143 - The copy module now "copies" function objects (as atomic objects).
2144 - dict.__getitem__ now looks for a __missing__ hook before raising
2145 KeyError.
2146
Tim Peters84ef21c2006-02-28 20:39:06 +00002147- PEP 343: with statement implemented. Needs ``from __future__ import
2148 with_statement``. Use of 'with' as a variable will generate a warning.
2149 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002150 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002151 The following objects have __context__ methods:
2152 - The built-in file type.
2153 - The thread.LockType type.
2154 - The following types defined by the threading module:
2155 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2156 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002157
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002158- Fix the encodings package codec search function to only search
2159 inside its own package. Fixes problem reported in patch #1433198.
2160
2161 Note: Codec packages should implement and register their own
2162 codec search function. PEP 100 has the details.
2163
Tim Peters9ea89d22006-06-04 03:26:02 +00002164- PEP 353: Using ``Py_ssize_t`` as the index type.
2165
2166- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2167 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2168 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2169 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2170 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002171
Neal Norwitzfc76d632006-01-10 06:03:13 +00002172- Patch #1400181, fix unicode string formatting to not use the locale.
2173 This is how string objects work. u'%f' could use , instead of .
2174 for the decimal point. Now both strings and unicode always use periods.
2175
Neal Norwitz671b9e32006-01-09 07:07:12 +00002176- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2177 configure would break checking curses.h.
2178
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002179- Bug #959576: The pwd module is now builtin. This allows Python to be
2180 built on UNIX platforms without $HOME set.
2181
Neal Norwitzc10978f2005-12-19 06:07:16 +00002182- Bug #1072182, fix some potential problems if characters are signed.
2183
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002184- Bug #889500, fix line number on SyntaxWarning for global declarations.
2185
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002186- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2187
Neal Norwitze7214a12005-12-18 05:03:17 +00002188- Support for converting hex strings to floats no longer works.
2189 This was not portable. float('0x3') now raises a ValueError.
2190
Barry Warsaw2a38a862005-12-18 01:27:35 +00002191- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002192 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002193 is now displayed in interactive prompt banner.
2194
Georg Brandlfa166682005-12-17 21:45:17 +00002195- Implementation of PEP 341 - Unification of try/except and try/finally.
2196 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002197 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002198
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002199- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2200 now encodes backslash correctly.
2201
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002202- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2203
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002204- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002205 and long longs.
2206
Neal Norwitz67715f02005-11-09 06:59:35 +00002207- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002208 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002209 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002210
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002211- Replaced most Unicode charmap codecs with new ones using the
2212 new Unicode translate string feature in the builtin charmap
2213 codec; the codecs were created from the mapping tables available
2214 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2215 encodings now include a mapping for the Apple logo)
2216
Tim Peterse3547fd2005-12-16 23:13:57 +00002217- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002218
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002219- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002220
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002221- A new AST parser implementation was completed. The abstract
2222 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002223 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002224
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002225- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002226 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2227
Neal Norwitz708e51a2005-10-03 04:48:15 +00002228- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2229
Neal Norwitz11bd1192005-10-03 00:54:56 +00002230- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2231 Provide a warning when a directory is passed on the command line.
2232
Neal Norwitz40d37812005-10-02 01:48:49 +00002233- Fix segfault with invalid coding.
2234
2235- SF bug #772896: unknown encoding results in MemoryError.
2236
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002237- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002238 supported a __len__() method which evaluated to False when the iterator
2239 was empty.
2240
Guido van Rossum630db602005-09-20 18:49:54 +00002241- On 64-bit platforms, when __len__() returns a value that cannot be
2242 represented as a C int, raise OverflowError.
2243
Skip Montanarof8948ca2005-09-19 03:54:46 +00002244- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002245 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002246
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002247- SF bug #893549: parsing keyword arguments was broken with a few format
2248 codes.
2249
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002250- Changes donated by Elemental Security to make it work on AIX 5.3
2251 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2252 bug #105470: test_pwd fails on 64bit system (Opteron).
2253
Guido van Rossum539c6622005-09-14 17:49:54 +00002254- Changes donated by Elemental Security to make it work on HP-UX 11 on
2255 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2256
Georg Brandl4550b8d2005-08-26 06:43:52 +00002257- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002258 (fixes bug #1119418).
2259
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002260- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2261
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002262- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2263 exceptions that cause a function to exit.
2264
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002265- The implementation of set() and frozenset() was revised to use its
2266 own internal data structure. Memory consumption is reduced by 1/3
2267 and there are modest speed-ups as well. The API is unchanged.
2268
Tim Petersde7990b2005-07-17 23:45:23 +00002269- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2270
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002271- SF bug #1229429: PyObject_CallMethod failed to decrement some
2272 reference counts in some error exit cases.
2273
Tim Petersecc6e6a2005-07-10 22:30:55 +00002274- SF bug #1185883: Python's small-object memory allocator took over
2275 a block managed by the platform C library whenever a realloc specified
2276 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002277 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002278 portable way to copy data from the C-managed block into Python's
2279 small-object space without risking a memory fault. Python's small-object
2280 realloc now leaves such blocks under the control of the platform C
2281 realloc.
2282
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002283- SF bug #1232517: An overflow error was not detected properly when
2284 attempting to convert a large float to an int in os.utime().
2285
Raymond Hettinger3296e692005-06-29 23:29:56 +00002286- SF bug #1224347: hex longs now print with lowercase letters just
2287 like their int counterparts.
2288
Michael W. Hudson188d4362005-06-20 16:52:57 +00002289- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2290 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2291 interpreter states; back out that fix and do a better job (see
2292 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2293 for a longer write-up of the problem).
2294
Michael W. Hudsondf888462005-06-03 14:41:55 +00002295- SF patch #1180995: marshal now uses a binary format by default when
2296 serializing floats.
2297
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002298- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2299 the routines that promise to produce IEEE 754 binary representations
2300 of floats now simply copy bytes around.
2301
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002302- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2303 278.
2304
Brett Cannonc3647ac2005-04-26 03:45:26 +00002305- patch #1109424: int, long, float, complex, and unicode now check for the
2306 proper magic slot for type conversions when subclassed. Previously the
2307 magic slot was ignored during conversion. Semantics now match the way
2308 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002309 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002310 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002311 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002312
Barry Warsawc8d907c2005-04-19 23:43:40 +00002313- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2314 NULL, now raise an AttributeError when attempting to set or delete the
2315 attribute. Previously a TypeError was raised, but this was inconsistent
2316 with the equivalent pure-Python implementation.
2317
Michael W. Hudson774479c2005-04-18 08:46:17 +00002318- It is now safe to call PyGILState_Release() before
2319 PyEval_InitThreads() (note that if there is reason to believe there
2320 are multiple threads around you still must call PyEval_InitThreads()
2321 before using the Python API; this fix is for extension modules that
2322 have no way of knowing if Python is multi-threaded yet).
2323
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002324- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2325 disabled caused a crash.
2326
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002327- Bug #1165306: instancemethod_new allowed the creation of a method
2328 with im_class == im_self == NULL, which caused a crash when called.
2329
Tim Petersecc6e6a2005-07-10 22:30:55 +00002330- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002331 fixes the crash seen in bug #1165761
2332
Raymond Hettinger96229b12005-03-11 06:49:40 +00002333- Added two new builtins, any() and all().
2334
Brett Cannon409d8f22005-03-05 06:47:57 +00002335- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002336 (e.g., ``class C(): pass`` is no longer a syntax error).
2337 Patch #1176012 added support to the 'parser' module and 'compiler' package
2338 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002339
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002340- Patch #1115086: Support PY_LONGLONG in structmember.
2341
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002342- Bug #1155938: new style classes did not check that __init__() was
2343 returning None.

Tim Petersf4e69282006-02-27 17:15:31 +00002375- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2376 current thread state when the auto-GIL-state machinery knows about
2377 it (since the thread state is being deleted, continuing to remember it
2378 can't help, but can hurt if another thread happens to get created with
2379 the same thread id).

Nick Coghlan43832302006-04-23 17:04:07 +00002575- PEP 338: new module runpy defines a run_module function to support
2576 executing modules which provide access to source code or a code object
2577 via the PEP 302 import mechanisms.

2587 in attribute values.
2588
Anthony Baxterc51ee692006-04-01 00:57:31 +00002589- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002590 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002591 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002592 module will not be built.

Tim Petersc17976e2006-04-01 00:26:53 +00002594- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2595 aren't officially supported here, and trying to use them will probably

2617
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002618- email 4.0 package now integrated. This is largely the same as the email 3.0
2619 package that was included in Python 2.3, except that PEP 8 module names are
2620 now used (e.g. mail.message instead of email.Message). The MIME classes
2621 have been moved to a subpackage (e.g. email.mime.text instead of
2622 email.MIMEText). The old names are still supported for now. Several
2623 deprecated Message methods have been removed and lots of bugs have been
2624 fixed. More details can be found in the email package documentation.

2627 (a subclass of tuple) that provides incremental decoders and encoders
2628 (a way to use stateful codecs without the stream API). Python functions
2629 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2630 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2631 have been added.

2634 a ValueError instead of a StopIteration now (like file and cString.String do).
2635 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2636 called before (like file and StringIO.StringIO do).

Tim Peterse3547fd2005-12-16 23:13:57 +00002710 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2711 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2712 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2713 Ronald L. Rivest offered this advice for Python:
2714
2715 "The consensus of researchers in this area (at least as
2716 expressed at the NIST Hash Function Workshop 10/31/05),
2717 is that SHA-256 is a good choice for the time being, but
2718 that research should continue, and other alternatives may
2719 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002720

2873
Martin v. Löwis4afe1542005-03-01 08:09:28 +00002874- Patch #1121234: Properly cleanup _exit and tkerror commands.
2875

2877
Raymond Hettingerbab41432005-02-05 01:31:19 +00002878- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2879
Guido van Rossumd0641422005-02-03 15:01:24 +00002880- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2881 disables recursive traversal through instance attributes, which can
2882 be exploited in various ways.
2883
Tim Peterse3547fd2005-12-16 23:13:57 +00002884- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002885 flags on the HTTP listening socket.
2886
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002887- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2888 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2889
Fred Drakefbdeaad2006-07-29 16:56:15 +00002890- Patches #893642, #1039083: add allow_none, encoding arguments to
2891 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.

2896
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002897- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2898
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002899- Enhancements to the csv module:
2900
2901 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002902 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002903 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002904 + Dialect parameter parsing has been re-implemented to improve error
2905 reporting.
2906 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2907 dictates.
2908 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002909 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002910 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002911 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2912 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002913 + reader now allows \r characters to be quoted (previously it only allowed
2914 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002915 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002916 + Dialect classes passed to the module are no longer instantiated by
2917 the module before being parsed (the former validation scheme required
2918 this, but the mechanism was unreliable).
2919 + The dialect registry now contains instances of the internal
2920 C-coded dialect type, rather than references to python objects.
2921 + the internal c-coded dialect type is now immutable.
2922 + register_dialect now accepts the same keyword dialect specifications
2923 as the reader and writer, allowing the user to register dialects
2924 without first creating a dialect class.
2925 + a configurable limit to the size of parsed fields has been added -
2926 previously, an unmatched quote character could result in the entire
2927 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002928 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002929 the parser field size limit (returning the former limit). The initial
2930 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002931 + A line_num attribute has been added to the reader object, which tracks
2932 the number of lines read from the source iterator. This is not
2933 the same as the number of records returned, as records can span
2934 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002935 + reader and writer objects were not being registered with the cyclic-GC.
2936 This has been fixed.
2937
Brett Cannone6539c42005-01-08 02:43:53 +00002938- _DummyThread objects in the threading module now delete self.__block that is
2939 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2940 lock primitives tend to be limited in number and thus should not be wasted on
2941 a _DummyThread object. Fixes bug #1089632.
2942
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002943- The imghdr module now detects Exif files.
2944
Raymond Hettinger6065d322004-12-20 23:51:53 +00002945- StringIO.truncate() now correctly adjusts the size attribute.
2946 (Bug #951915).
2947
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002948- locale.py now uses an updated locale alias table (built using
2949 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2950 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002951 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002952
Raymond Hettinger3557f422004-12-07 12:02:02 +00002953- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2954
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002955- the pickle module no longer accepts the deprecated None option in the
2956 args tuple returned by __reduce__().
2957
Brett Cannon84667c02004-12-07 03:25:18 +00002958- optparse now optionally imports gettext. This allows its use in setup.py.
2959
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002960- the pickle module no longer uses the deprecated bin parameter.
2961
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002962- the shelve module no longer uses the deprecated binary parameter.
2963
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002964- the pstats module no longer uses the deprecated ignore() method.
2965
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002966- the filecmp module no longer uses the deprecated use_statcache argument.
2967
Raymond Hettinger664347b2004-12-04 21:21:53 +00002968- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2969 extended or overridden by subclasses. Formerly, the subclassed method would
2970 be ignored by the rest of the module. (Bug #1078905).
2971
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002972- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002973 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002974
Walter Dörwald36733692004-12-22 12:50:50 +00002975- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2976 once when a size argument is given. This prevents a buffer overflow in the
2977 tokenizer with very long source lines.
2978
Barry Warsaw538561e2006-01-01 21:48:54 +00002979- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
2980 immediately after creating the object, without any intervening
2981 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00002982
Skip Montanaro05885812005-01-16 20:48:27 +00002983- The reconvert.quote function can now emit triple-quoted strings. The
2984 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002985
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00002986- ``UserString.MutableString`` now supports negative indices in
2987 ``__setitem__`` and ``__delitem__``
2988
Greg Ward40407942005-03-05 02:53:17 +00002989- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
2990 correctly.
2991
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00002992- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
2993 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
2994 character even if the user has passed a size parameter to get a proper
2995 line ending. Remove the special handling of a "\r\n" that has been split
2996 between two lines.
2997
Walter Dörwalda47d1c02005-08-30 10:23:14 +00002998- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
2999 about illegal code points. The codec now supports PEP 293 style error
3000 handlers.
3001
Walter Dörwald78a78b02005-09-01 12:04:29 +00003002- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003003 from the input stream, so that the output is a byte string in the correct
3004 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003005
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003006- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3007 considering it exactly like a '*'.
3008
Walter Dörwald007f8df2005-10-09 19:42:27 +00003009- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3010 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003011
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003012- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3013
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003014- Patch #1413711: Certain patterns of differences were making difflib
3015 touch the recursion limit.
3016
Walter Dörwald58917a62006-03-31 15:26:22 +00003017- Bug #947906: An object oriented interface has been added to the calendar
3018 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003019 called as a script (e.g. via ``python -mcalendar``). Localized month and
3020 weekday names can be ouput (even if an exotic encoding is used) using
3021 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003022
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003023Build
3024-----
3025
Neal Norwitz602d3392006-03-31 08:21:40 +00003026- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3027 by using -mieee gcc option.
3028

3030
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003031- Build support for Win64-AMD64 was added.
3032
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003033- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3034
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003035- Patch #881820: look for openpty and forkpty also in libbsd.
3036
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003037- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3038 The zlib module is now builtin on Windows.
3039
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003040- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3041
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003042- Bug #1189330: configure did not correctly determine the necessary
3043 value of LINKCC if python was built with GCC 4.0.
3044
Trent Mick8321b422005-07-26 02:29:21 +00003045- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3046 vulnerability in zlib 1.2.1 and 1.2.2.
3047
Brett Cannon08cd5982005-04-24 22:26:38 +00003048- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3049 flags that change binary compatibility. Changes were also made to
3050 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003051 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003052
Bob Ippolitoed233462005-03-29 13:47:59 +00003053- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3054 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3055 no longer exists). This configure patch makes things right.
3056
Martin v. Löwise2713be2005-03-08 15:03:08 +00003057- Bug #1158607: Build with --disable-unicode again.
3058
Brett Cannon46d96232005-02-16 00:07:19 +00003059- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3060 defined. Discovered as a result of not being able to build on OS X.
3061
Brett Cannon516592f2004-12-07 00:42:59 +00003062- setup.py now uses the directories specified in LDFLAGS using the -L option
3063 and in CPPFLAGS using the -I option for adding library and include
3064 directories, respectively, for compiling extension modules against. This has
3065 led to the core being compiled using the values in CPPFLAGS. It also removes
3066 the need for the special-casing of both DarwinPorts and Fink for darwin since
3067 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3068 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3069 Fink, ``-I/opt/local/include`` for DarwinPorts).
3070
Brett Cannon43802422005-02-10 20:48:03 +00003071- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3072 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3073 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3074 Closes bug #1096244. Thanks Gregory Bond.
3075
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003076C API
3077-----
3078
Tim Petersc9d78aa2006-03-26 23:27:58 +00003079- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3080 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3081 is obtained via the ``PyObject_`` family, it must be released via the
3082 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3083 always been officially true, but when Python's small-object allocator was
3084 introduced, an attempt was made to cater to a few extension modules
3085 discovered at the time that obtained memory via ``PyObject_New`` but
3086 released it via ``PyMem_DEL``. It's years later, and if such code still
3087 exists it will fail now (probably with segfaults, but calling wrong
3088 low-level memory management functions can yield many symptoms).
3089
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003090- Added a C API for set and frozenset objects.
3091
Raymond Hettinger66517482004-12-03 11:45:13 +00003092- Removed PyRange_New().
3093
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003094- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3095 mapping argument now. This string is used as a mapping table. Byte values
3096 greater than the length of the string and 0xFFFE are treated as undefined
3097 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003104
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00003105- Patch #1276356: New resource "urlfetch" is implemented. This enables
