15- Issue #1477: With narrow Unicode builds, the unicode escape sequence
16 \Uxxxxxxxx did not accept values outside the Basic Multilingual Plane. This

19 and the 'unicode-escape' codec.

919-----------------
920
Neal Norwitz0bcafac2006-09-11 08:51:17 +0000921- Make _PyGILState_NoteThreadState() static, it was not used anywhere
922 outside of pystate.c and should not be necessary.
923
Brett Cannon19d76c52006-09-09 07:18:44 +0000924- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
925 allows calling unicode() on exceptions classes directly to succeed.
926
Georg Brandlecab6232006-09-06 06:47:02 +0000927- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
928 Also make sure that every exception class has __module__ set to
929 'exceptions'.
930
Georg Brandl37a9e572006-09-06 06:09:34 +0000931- Bug #1550983: emit better error messages for erroneous relative
932 imports (if not in package and if beyond toplevel package).
933
Tim Peterscbdd3502006-09-05 01:47:53 +0000934- Overflow checking code in integer division ran afoul of new gcc
935 optimizations. Changed to be more standard-conforming.

941
Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000942- The return tuple from str.rpartition(sep) is (tail, sep, head) where
943 head is the original string if sep was not found.
944
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000945- Bug #1520864: unpacking singleton tuples in list comprehensions and
946 generator expressions (x for x, in ... ) works again. Fixing this problem
947 required changing the .pyc magic number. This means that .pyc files
948 generated before 2.5c2 will be regenerated.

1061-----------------
1062
Neal Norwitz24b6f202006-09-05 04:43:56 +00001063- Fix infinite recursion when subclassing long and overriding __hash__.
1064
1065- Fix concatenation (+=) of long strings.
1066
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001067- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001068 compared equal or unequal to a string and a UnicodeDecodeError
1069 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001070
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001071 Instead, the equal (==) and unequal (!=) comparison operators will
1072 now issue a UnicodeWarning and interpret the two objects as
1073 unequal. The UnicodeWarning can be filtered as desired using
1074 the warning framework, e.g. silenced completely, turned into an
1075 exception, logged, etc.
1076
1077 Note that compare operators other than equal and unequal will still
1078 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001079
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001080- Fix segfault when doing string formatting on subclasses of long.
1081
1082- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1083 with new-style classes.
1084
1085- Fix bug related to __len__ functions returning negative values with
1086 classic classes.
1087
1088- Patch #1538606, Fix __index__() clipping. There were some problems
1089 discovered with the API and how integers that didn't fit into Py_ssize_t
1090 were handled. This patch attempts to provide enough alternatives
1091 to effectively use __index__.
1092
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001093- Bug #1536021: __hash__ may now return long int; the final hash
1094 value is obtained by invoking hash on the long int.
1095
Thomas Hellerab1049c2006-08-08 17:37:00 +00001096- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1097
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001098- Bug #1535165: fixed a segfault in input() and raw_input() when
1099 sys.stdin is closed.
1100
Thomas Heller74d36f02006-08-04 18:17:40 +00001101- On Windows, the PyErr_Warn function is now exported from
1102 the Python dll again.
1103
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001104- Bug #1191458: tracing over for loops now produces a line event
1105 on each iteration. Fixing this problem required changing the .pyc
1106 magic number. This means that .pyc files generated before 2.5c1
1107 will be regenerated.
1108
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001109- Bug #1333982: string/number constants were inappropriately stored
1110 in the byte code and co_consts even if they were not used, ie
1111 immediately popped off the stack.
1112
Georg Brandle9462c72006-08-04 18:03:37 +00001113- Fixed a reference-counting problem in property().

1117-------
1118
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001119- Fix a bug in the ``compiler`` package that caused invalid code to be
1120 generated for generator expressions.
1121
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001122- The distutils version has been changed to 2.5.0. The change to
1123 keep it programmatically in sync with the Python version running
1124 the code (introduced in 2.5b3) has been reverted. It will continue
1125 to be maintained manually as static string literal.
1126
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001127- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001128 and this cannot be converted to the required C type, an exception is
1129 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001130 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001131
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001132- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001133 an exception.
1134
Tim Peterscbdd3502006-09-05 01:47:53 +00001135- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001136 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001137 workarounds for clocks with low resolution, to stop the code yielding
1138 duplicate UUIDs.
1139
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001140- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1141 before raising SystemExit, allowing IDLE to honor quit() and exit().
1142
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001143- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1144
Georg Brandl7a1af772006-08-14 21:55:28 +00001145- Patch #1536071: trace.py should now find the full module name of a
1146 file correctly even on Windows.
1147
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001148- logging's atexit hook now runs even if the rest of the module has
1149 already been cleaned up.
1150
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001151- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001152
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001153- Bug #1531405, format_exception no longer raises an exception if
1154 str(exception) raised an exception.
1155
Neil Schemenauer06ded092006-08-04 16:20:30 +00001156- Fix a bug in the ``compiler`` package that caused invalid code to be
1157 generated for nested functions.

1172
Thomas Heller86720042006-08-14 11:17:48 +00001173- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1174 uses the _as_parameter_ attribute when objects are passed to foreign
1175 function calls. The ctypes version number was changed to 1.0.1.
1176
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001177- Bug #1530559, struct.pack raises TypeError where it used to convert.
1178 Passing float arguments to struct.pack when integers are expected
1179 now triggers a DeprecationWarning.

Fred Drake53912162006-07-29 13:22:49 +00001224What's New in Python 2.5 beta 3?
1225================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001226
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001227*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001228
1229Core and builtins
1230-----------------
1231
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001232- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001233 returned a long (see PEP 353).
1234
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001235- Bug #1515471: string.replace() accepts character buffers again.
1236
Neal Norwitz07aadb12006-07-30 06:55:48 +00001237- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1238 This provides the proper warning for struct.pack().
1239 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1240
Neal Norwitz0d62a062006-07-30 06:53:31 +00001241- Patch #1531113: Fix augmented assignment with yield expressions.
1242 Also fix a SystemError when trying to assign to yield expressions.
1243
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001244- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1245 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1246 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1247 excessive filesystem operations during imports.
1248
Tim Petersbc24eee2006-07-27 01:14:53 +00001249- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1250 operations on signed longs that are formally undefined by C.
1251 Unfortunately, at least one compiler now cares about that, so complicated
1252 the code to make that compiler happy again.
1253
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001254- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1255
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001256- Patch #1232023: Stop including current directory in search
1257 path on Windows.
1258
Neal Norwitze1fdb322006-07-21 05:32:28 +00001259- Fix some potential crashes found with failmalloc.
1260
Neal Norwitze7563102006-07-17 01:00:16 +00001261- Fix warnings reported by Klocwork's static analysis tool.
1262
Neal Norwitz84be93b2006-07-16 01:50:38 +00001263- Bug #1512814, Fix incorrect lineno's when code within a function
1264 had more than 255 blank lines.
1265
Georg Brandl9dceedb2006-07-12 15:31:17 +00001266- Patch #1521179: Python now accepts the standard options ``--help`` and
1267 ``--version`` as well as ``/?`` on Windows.
1268
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001269- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001270 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001271 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001272
Tim Peters112aad32006-07-19 00:03:19 +00001273- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001274 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001275 new ``sys._current_frames()`` returns a dictionary with one entry,
1276 mapping the faux "thread id" 0 to the current frame.
1277
Ronald Oussoren3075e162006-07-25 20:28:55 +00001278- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001279
Ronald Oussoren3075e162006-07-25 20:28:55 +00001280
Neal Norwitza1f10902006-07-12 07:28:29 +00001281Library
1282-------
1283
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001284- Correction of patch #1455898: In the mbcs decoder, set final=False
1285 for stream decoder, but final=True for the decode function.
1286
Georg Brandl07fec3a2006-08-01 18:49:24 +00001287- os.urandom no longer masks unrelated exceptions like SystemExit or
1288 KeyboardInterrupt.
1289
Tim Peters4643c2f2006-08-10 22:45:34 +00001290- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001291 shutil.copytree on Windows
1292
Georg Brandle34ac7c2006-07-30 11:07:23 +00001293- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1294 refers to file descriptors, not file objects.
1295
Tim Peterscbdd3502006-09-05 01:47:53 +00001296- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001297 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001298 #1513611, and probably others.
1299
Georg Brandledd9b0d2006-07-29 09:33:26 +00001300- Bug #1441397: The compiler module now recognizes module and function
1301 docstrings correctly as it did in Python 2.4.
1302
Tim Peters6f681472006-07-27 23:44:37 +00001303- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1304 lost that tests are sorted by name before being run. This rarely
1305 matters for well-written tests, but can create baffling symptoms if
1306 side effects from one test to the next affect outcomes. ``DocTestFinder``
1307 has been changed to sort the list of tests it returns.
1308
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001309- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001310 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001311
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001312- Bug #978833: Really close underlying socket in _socketobject.close.
1313
Georg Brandldb232dc2006-08-20 13:15:43 +00001314- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1315 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001316
Georg Brandlcf0c1722006-07-26 07:23:32 +00001317- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1318 to recursive calls and call it with the failing package name.
1319
Martin v. Löwis0b483032006-07-25 09:53:12 +00001320- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1321
Georg Brandlc13c34c2006-07-24 14:09:56 +00001322- Patch #1515343: Fix printing of deprecated string exceptions with a
1323 value in the traceback module.
1324
Greg Ward48fae7a2006-07-23 16:05:51 +00001325- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1326
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001327- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1328
Brett Cannoncaebe222006-07-18 04:41:36 +00001329- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1330 argument tuple. For arguments where zero is illegal, the value is forced to
1331 the minimum value that is correct. This is to support an undocumented but
1332 common way people used to fill in inconsequential information in the time
1333 tuple pre-2.4.
1334
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001335- Patch #1220874: Update the binhex module for Mach-O.
1336
Barry Warsawb110bad2006-07-21 14:51:07 +00001337- The email package has improved RFC 2231 support, specifically for
1338 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1339 (name*0=<blah>) parameter continuations. This may change the types of
1340 values returned from email.message.Message.get_param() and friends.
1341 Specifically in some cases where non-encoded continuations were used,
1342 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1343 will just return the string (since non-encoded continuations don't have
1344 charset and language parts).
1345
1346 Also, whereas % values were decoded in all parameter continuations, they are
1347 now only decoded in encoded parameter parts.
1348
Ronald Oussoren3075e162006-07-25 20:28:55 +00001349- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1350
1351- Bug #1517996: IDLE now longer shows the default Tk menu when a
1352 path browser, class browser or debugger is the frontmost window on MacOS X
1353
Barry Warsaw00decd72006-07-27 23:43:15 +00001354- Patch #1520294: Support for getset and member descriptors in types.py,
1355 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1356 of an object against these built-in types and more importantly, for getting
1357 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001360Extension Modules
1361-----------------
1362
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001363- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1364 a socket operation on a socket with a timeout, the exception will be
1365 caught correctly. Previously, the exception was not caught.
1366
Thomas Heller1393d6a2006-07-28 21:43:20 +00001367- Patch #1529514: The _ctypes extension is now compiled on more
1368 openbsd target platforms.
1369
Tim Peters9cab5932006-07-28 00:30:00 +00001370- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1371 a memory leak, affecting pickles and deep copies.
1372
Tim Petersbc24eee2006-07-27 01:14:53 +00001373- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001374 Paul Eggert.
1375
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001376- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1377
Thomas Hellerce049a02006-07-14 17:51:14 +00001378- Patch #1521817: Index range checking on ctypes arrays containing
1379 exactly one element enabled again. This allows iterating over these
1380 arrays, without the need to check the array size before.
1381
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001382- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001383 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001384 /dev/null in certain cases; this is now fixed.
1385
Thomas Heller47d7a062006-07-12 08:43:47 +00001386- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1387 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001388
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001389- Because of a misspelled preprocessor symbol, ctypes was always
1390 compiled without thread support; this is now fixed.
1391
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001392- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1393 methods now allow their database parameter to be None as the
1394 sleepycat API allows.
1395
Matt Flemingec926502006-07-28 11:27:27 +00001396- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1397 bluetooth API compared with Linux and FreeBSD.
1398
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001399Tests
1400-----
1401
1402- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1403 how long the test file should take to play. Now accepts taking 2.93 secs
1404 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1405
Georg Brandl4793aa32006-07-28 18:31:39 +00001406- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1407 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1408 run via ``regrtest.py``. Now they do.

1417
1418- PythonLauncher now works correctly when the path to the script contains
1419 characters that are treated specially by the shell (such as quotes).
1420
1421- Bug #1527397: PythonLauncher now launches scripts with the working directory
1422 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001423 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001424 expect.

1434
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001435- Bug #1441486: The literal representation of -(sys.maxint - 1)
1436 again evaluates to a int object, not a long.
1437
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001438- Bug #1501934: The scope of global variables that are locally assigned
1439 using augmented assignment is now correctly determined.
1440
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001441- Bug #927248: Recursive method-wrapper objects can now safely
1442 be released.
1443
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001444- Bug #1417699: Reject locale-specific decimal point in float()
1445 and atof().
1446
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001447- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1448 omit a default "error" argument for NULL pointer. This allows
1449 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001450
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001451- Bug #1519018: 'as' is now validated properly in import statements.
1452
Neal Norwitz28746ab2006-07-09 22:14:42 +00001453- On 64 bit systems, int literals that use less than 64 bits are
1454 now ints rather than longs.
1455
Neal Norwitzed657552006-07-10 00:04:44 +00001456- Bug #1512814, Fix incorrect lineno's when code at module scope
1457 started after line 256.
1458
Tim Peters32a83612006-07-10 21:08:24 +00001459- New function ``sys._current_frames()`` returns a dict mapping thread
1460 id to topmost thread stack frame. This is for expert use, and is
1461 especially useful for debugging application deadlocks. The functionality
1462 was previously available in Fazal Majid's ``threadframe`` extension
1463 module, but it wasn't possible to do this in a wholly threadsafe way from
1464 an extension.

Martin v. Löwis388a8c22006-07-06 19:28:03 +00001478- Bug #1515998: Properly generate logical ids for files in bdist_msi.
1479
Nick Coghlan2d792252006-07-06 13:47:18 +00001480- warnings.py now ignores ImportWarning by default
1481
Thomas Woutersadd19112006-07-05 11:03:49 +00001482- string.Template() now correctly handles tuple-values. Previously,
1483 multi-value tuples would raise an exception and single-value tuples would
1484 be treated as the value they contain, instead.
1485
Martin v. Löwisede77f52006-07-03 13:01:35 +00001486- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1487 even if some data are received.
1488
Martin v. Löwis45482392006-07-03 12:28:58 +00001489- Bug #1267547: Put proper recursive setup.py call into the
1490 spec file generated by bdist_rpm.
1491
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001492- Bug #1514693: Update turtle's heading when switching between
1493 degrees and radians.
1494
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001495- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001496 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001497
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001498- Bug #1514703: Only setup canvas window in turtle when the canvas
1499 is created.
1500
Martin v. Löwis7596e832006-07-01 15:33:37 +00001501- Bug #1513223: .close() of a _socketobj now releases the underlying
1502 socket again, which then gets closed as it becomes unreferenced.
1503
Fred Drake10497c82006-06-29 02:57:48 +00001504- Bug #1504333: Make sgmllib support angle brackets in quoted
1505 attribute values.
1506
1507- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1508 sgmllib ('[' and ']' were not accepted).
1509
Georg Brandl1be63af2006-06-28 20:23:25 +00001510- Fix a bug in the turtle module's end_fill function.
1511
Brett Cannon53ab5b72006-06-22 16:49:14 +00001512- Bug #1510580: The 'warnings' module improperly required that a Warning
1513 category be either a types.ClassType and a subclass of Warning. The proper
1514 check is just that it is a subclass with Warning as the documentation states.
1515
Georg Brandlad29e632006-06-21 17:45:17 +00001516- The compiler module now correctly compiles the new try-except-finally
1517 statement (bug #1509132).
1518
Neal Norwitz60373cd2006-06-22 06:30:50 +00001519- The wsgiref package is now installed properly on Unix.
1520
Vinay Sajip28e57612006-07-01 10:45:20 +00001521- A bug was fixed in logging.config.fileConfig() which caused a crash on
1522 shutdown when fileConfig() was called multiple times.
1523
Gerhard Häring762fbd32006-07-02 17:48:30 +00001524- The sqlite3 module did cut off data from the SQLite database at the first
1525 null character before sending it to a custom converter. This has been fixed
1526 now.
1527
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001528Extension Modules
1529-----------------
1530
Tim Peters112aad32006-07-19 00:03:19 +00001531- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1532 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1533 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001534
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001535- Assigning None to pointer type fields in ctypes structures possible
1536 overwrote the wrong fields, this is fixed now.
1537
1538- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1539 on non-Windows platforms.
1540
1541- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1542 integer or long, without range checking.
1543
1544- Patch #1517790: It is now possible to use custom objects in the ctypes
1545 foreign function argtypes sequence as long as they provide a from_param
1546 method, no longer is it required that the object is a ctypes type.
1547
1548- The '_ctypes' extension module now works when Python is configured
1549 with the --without-threads option.
1550
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001551- Bug #1513646: os.access on Windows now correctly determines write
1552 access, again.
1553
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001554- Bug #1512695: cPickle.loads could crash if it was interrupted with
1555 a KeyboardInterrupt.
1556
Neal Norwitza12aa882006-07-06 06:45:08 +00001557- Bug #1296433: parsing XML with a non-default encoding and
1558 a CharacterDataHandler could crash the interpreter in pyexpat.
1559
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001560- Patch #1516912: improve Modules support for OpenVMS.

1563-----
1564
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001565- Automate Windows build process for the Win64 SSL module.
1566
Tim Peters32a83612006-07-10 21:08:24 +00001567- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001568 Previously, the slight difference could cause compilation errors of the
1569 'zlib' module on systems with more than one version of zlib.
1570
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001571- The MSI compileall step was fixed to also support a TARGETDIR
1572 with spaces in it.

1575 of Tcl/Tk.
1576
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001577- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001578 trying to be installed even though it's empty.

1590 documentation for the warnings module.
1591
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001592- Patch #1509163: MS Toolkit Compiler no longer available.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001601
1602Core and builtins
1603-----------------
1604
Georg Brandla56b9152006-06-19 06:35:54 +00001605- Patch #1507676: Error messages returned by invalid abstract object operations
1606 (such as iterating over an integer) have been improved and now include the
1607 type of the offending object to help with debugging.
1608
Brett Cannonea3912b2006-06-13 21:46:41 +00001609- Bug #992017: A classic class that defined a __coerce__() method that returned
1610 its arguments swapped would infinitely recurse and segfault the interpreter.
1611
Neal Norwitz909eb122006-06-12 02:13:21 +00001612- Fix the socket tests so they can be run concurrently.
1613
Neal Norwitzb9845e72006-06-12 02:11:18 +00001614- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001615 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001616
Brett Cannon22565aa2006-06-09 22:31:23 +00001617- Bug #532646: object.__call__() will continue looking for the __call__
1618 attribute on objects until one without one is found. This leads to recursion
1619 when you take a class and set its __call__ attribute to an instance of the
1620 class. Originally fixed for classic classes, but this fix is for new-style.
1621 Removes the infinite_rec_3 crasher.
1622
Georg Brandl24250812006-06-09 18:45:48 +00001623- The string and unicode methods startswith() and endswith() now accept
1624 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1625
Brett Cannonde3b0522006-06-08 17:00:45 +00001626- Buffer objects, at the C level, never used the char buffer
1627 implementation even when the char buffer for the wrapped object was
1628 explicitly requested (originally returned the read or write buffer).
1629 Now a TypeError is raised if the char buffer is not present but is
1630 requested.
1631
Georg Brandlddbaa662006-06-04 21:56:52 +00001632- Patch #1346214: Statements like "if 0: suite" are now again optimized
1633 away like they were in Python 2.4.
1634
Georg Brandlb7c8f542006-05-27 12:30:25 +00001635- Builtin exceptions are now full-blown new-style classes instead of
1636 instances pretending to be classes, which speeds up exception handling
1637 by about 80% in comparison to 2.5a2.
1638
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001639- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1640 Unicode 4.1.
1641
Georg Brandlf4ef1162006-05-26 18:03:31 +00001642- Patch #921466: sys.path_importer_cache is now used to cache valid and
1643 invalid file paths for the built-in import machinery which leads to
1644 fewer open calls on startup.
1645
Tim Peters696cf432006-05-24 21:10:40 +00001646- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1647 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1648 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1649 the number of input digits (it was and remains linear-time for bases
1650 2, 4, 8, 16 and 32).
1651
Tim Petersb713ec22006-05-23 18:45:30 +00001652- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1653 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1654 an integer close to ``sys.maxint``. This was repaired by patch
1655 #1335972, which also gives a nice speedup.
1656
Richard Jonescebbefc2006-05-23 18:28:17 +00001657- Patch #1337051: reduced size of frame objects.
1658
1659- PyErr_NewException now accepts a tuple of base classes as its
1660 "base" parameter.
1661
Richard Jones7c88dcc2006-05-23 10:37:38 +00001662- Patch #876206: function call speedup by retaining allocated frame
1663 objects.
1664
Georg Brandl7b90e162006-05-18 07:01:27 +00001665- Bug #1462152: file() now checks more thoroughly for invalid mode
1666 strings and removes a possible "U" before passing the mode to the
1667 C library function.
1668
Neal Norwitz1004a532006-05-15 07:17:23 +00001669- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1670
Neal Norwitz373f0a72006-05-15 07:04:36 +00001671- Bug #1487966: Fix SystemError with conditional expression in assignment
1672
Martin v. Löwis879768d2006-05-11 13:28:43 +00001673- WindowsError now has two error code attributes: errno, which carries
1674 the error values from errno.h, and winerror, which carries the error
1675 values from winerror.h. Previous versions put the winerror.h values
1676 (from GetLastError()) into the errno attribute.
1677
Martin v. Löwis77736712006-05-04 05:51:03 +00001678- Patch #1475845: Raise IndentationError for unexpected indent.
1679
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001680- Patch #1479181: split open() and file() from being aliases for each other.
1681
Tim Peters44bd9862006-06-01 13:49:23 +00001682- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1683 methods were always silently ignored by dictionaries when comparing keys.
1684 They are now passed through (except when using the C API function
1685 ``PyDict_GetItem()``, whose semantics did not change).
1686
1687- Bug #1456209: In some obscure cases it was possible for a class with a
1688 custom ``__eq__()`` method to confuse dict internals when class instances
1689 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1690 No, you don't have any code that did this ;-)

Brett Cannon6ee7d012006-06-08 16:23:04 +00001699- Change binascii.hexlify to accept a read-only buffer instead of only a char
1700 buffer and actually follow its documentation.
1701

1703
Nick Coghlanc649ec52006-05-29 12:43:05 +00001704- Patch #1478788 (modified version): The functional extension module has
1705 been renamed to _functools and a functools Python wrapper module added.
1706 This provides a home for additional function related utilities that are
1707 not specifically about functional programming. See PEP 309.
1708
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001709- Patch #1493701: performance enhancements for struct module.

1717 enabled builds on Windows and systems with Posix threads support.
1718
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001719- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1720 (up to the system limit of 32K characters).
1721
1722- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1723 As a result, these functions now raise WindowsError instead of OSError.
1724
Tim Peters7a822da2006-05-25 21:50:17 +00001725- ``time.clock()`` on Win64 should use the high-performance Windows
1726 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1727 Windows platforms).
1728
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001729- Calling Tk_Init twice is refused if the first call failed as that
1730 may deadlock.
1731
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001732- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1733 accept it without potentially using an uninitialized pointer.
1734
1735- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1736 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

1746 results. It could previously incorrectly return 0 in some cases.
1747 Fixes SF bug 1493322 (pybsddb bug 1184012).
1748
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001749- bsddb: the bsddb.dbtables Modify method now raises the proper error and

1751 Fixes SF python patch/bug #1408584.
1752
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001753- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001754 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001755 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1756 database calls that would previously deadlock. [SF python bug #775414]

1770
Vinay Sajip28e57612006-07-01 10:45:20 +00001771- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00001772 Tkinter.BaseWidget.
1773

1780 mime.types file for determining MIME types.
1781
Georg Brandl2605ca82006-06-14 06:08:31 +00001782- Bug #1339007: Shelf objects now don't raise an exception in their
1783 __del__ method when initialization failed.
1784
Martin v. Löwisd8251432006-06-14 05:21:04 +00001785- Patch #1455898: The MBCS codec now supports the incremental mode for
1786 double-byte encodings.
1787
Tim Peters43898b42006-06-14 04:09:25 +00001788- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1789 guarantee that adjacent triples in the return list always describe
1790 non-adjacent blocks. Previously, a pair of matching blocks could end
1791 up being described by multiple adjacent triples that formed a partition
1792 of the matching pair.
1793
Greg Ward0e0c9f42006-06-11 16:24:11 +00001794- Bug #1498146: fix optparse to handle Unicode strings in option help,
1795 description, and epilog.
1796
Greg Wardd1c797e2006-06-11 14:42:41 +00001797- Bug #1366250: minor optparse documentation error.
1798
Greg Ward7f547402006-06-11 00:40:49 +00001799- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1800 clarify docs.
1801
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001802- The wsgiref package has been added to the standard library.
1803
Nick Coghlan676725d2006-06-08 13:54:49 +00001804- The functions update_wrapper() and wraps() have been added to the functools
1805 module. These make it easier to copy relevant metadata from the original
1806 function when writing wrapper functions.
1807
Tim Petersd6a9eef2006-06-05 01:48:21 +00001808- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1809 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001810
Martin v. Löwis3f767792006-06-04 19:36:28 +00001811- Patch #1359618: Speed up charmap encoder by using a trie structure
1812 for lookup.
1813
Tim Petersd609b1a2006-06-02 23:22:51 +00001814- The functions in the ``pprint`` module now sort dictionaries by key
1815 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1816 if and only if its display required more than one line, although that
1817 wasn't documented. The new behavior increases predictability; e.g.,
1818 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1819
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001820- Patch #1497027: try HTTP digest auth before basic auth in urllib2
1821 (thanks for J. J. Lee).
1822
Georg Brandl2b330372006-05-28 20:23:12 +00001823- Patch #1496206: improve urllib2 handling of passwords with respect to
1824 default HTTP and HTTPS ports.
1825
George Yoshidaf3c65de2006-05-28 16:39:09 +00001826- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1827
Bob Ippolito7298f272006-05-23 18:43:47 +00001828- Patch #1281707: speed up gzip.readline.
1829
Georg Brandlb89316f2006-05-17 15:51:16 +00001830- Patch #1180296: Two new functions were added to the locale module:
1831 format_string() to get the effect of "format % items" but locale-aware,
1832 and currency() to format a monetary number with currency sign.
1833
Georg Brandle3a25832006-05-17 14:56:04 +00001834- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1835 and several features added, such as speed and geometry control.
1836
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001837- Patch #1488881: add support for external file objects in bz2 compressed
1838 tarfiles.
1839
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001840- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1841 stdout arguments, making it possible to redirect input and output
1842 for remote debugging.
1843
1844- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1845 a couple of issues, notably handling of long file names using the
1846 GNU LONGNAME extension.
1847
1848- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1849 new flag when ``name`` is already the name of an option flag.
1850
1851- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1852 package.
1853
1854- Patch #1472854: make the rlcompleter.Completer class usable on non-
1855 UNIX platforms.
1856
1857- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
1858
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00001859- Bug #1472827: correctly escape newlines and tabs in attribute values in
1860 the saxutils.XMLGenerator class.

1895Core and builtins
1896-----------------
1897
Thomas Heller1b046642006-04-18 18:51:06 +00001898- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1899 by converting these apis from macros into exported functions again:
1900
1901 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1902 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1903 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1904 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1905 PyRun_String Py_CompileString
1906
Martin v. Löwis45294a92006-04-18 06:24:08 +00001907- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1908
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001909- All uses of PyStructSequence_InitType have been changed to initialize
1910 the type objects only once, even if the interpreter is initialized
1911 multiple times.
1912
Neal Norwitz61546162006-04-14 05:20:28 +00001913- Bug #1454485, array.array('u') could crash the interpreter. This was
1914 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1915 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1916
1917- Py_UNICODE is unsigned. It was always documented as unsigned, but
1918 due to a bug had a signed value in previous versions.
1919
Tim Peters3a5e8b12006-04-11 01:44:07 +00001920- Patch #837242: ``id()`` of any Python object always gives a positive
1921 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1922 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001923 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001924 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001925
Tim Peters3a5e8b12006-04-11 01:44:07 +00001926 def __hash__(self):
1927 return id(self) # WRONG
1928
1929 because a hash result must be a (short) Python int but it was always
1930 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001931 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001932 was always usable as a hash value before this patch. That's no longer
1933 necessarily so.
1934
1935- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001936 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001937 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001938 #1454844)
1939
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001940- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1941 involving generators that have paused outside of any ``try`` or ``with``
1942 blocks. (In 2.5a1, a paused generator that was part of a reference
1943 cycle could not be garbage collected, regardless of whether it was
1944 paused in a ``try`` or ``with`` block.)

Georg Brandlbbfe4fa2006-04-11 06:47:43 +00001952- Bug #1467952: os.listdir() now correctly raises an error if readdir()
1953 fails with an error condition.
1954
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00001955- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
1956
1957- Bug #1117761: bsddb.*open() no longer raises an exception when using
1958 the cachesize parameter.
1959
1960- Bug #1149413: bsddb.*open() no longer raises an exception when using
1961 a temporary db (file=None) with the 'n' flag to truncate on open.
1962
1963- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
1964 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00001965
Armin Rigoa9017c32006-04-19 11:50:27 +00001966- Patch #1062014: AF_UNIX sockets under Linux have a special
1967 abstract namespace that is now fully supported.

Peter Astrand7d1d4362006-07-14 14:04:45 +00001972- Bug #1223937: subprocess.CalledProcessError reports the exit status
1973 of the process using the returncode attribute, instead of
1974 abusing errno.
1975
Tim Peters711bf302006-04-25 03:31:36 +00001976- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
1977 a doctest to be skipped (the code is not run, and the expected output
1978 or exception is ignored).
1979
Nick Coghlanda2268f2006-04-24 04:37:15 +00001980- Fixed contextlib.nested to cope with exceptions being raised and
1981 caught inside exit handlers.
1982
Greg Wardab05edc2006-04-23 03:47:58 +00001983- Updated optparse module to Optik 1.5.1 (allow numeric constants in
1984 hex, octal, or binary; add ``append_const`` action; keep going if
1985 gettext cannot be imported; added ``OptionParser.destroy()`` method;
1986 added ``epilog`` for better help generation).
1987
Tim Peters21fbd572006-04-21 21:18:10 +00001988- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
1989 called from a thread spawned as a side effect of importing a module.
1990
Phillip J. Eby17a35f92006-04-18 16:45:14 +00001991- The pydoc module now supports documenting packages contained in
1992 .zip or .egg files.
1993
1994- The pkgutil module now has several new utility functions, such
1995 as ``walk_packages()`` to support working with packages that are either
1996 in the filesystem or zip files.
1997
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00001998- The mailbox module can now modify and delete messages from
1999 mailboxes, in addition to simply reading them. Thanks to Gregory
2000 K. Johnson for writing the code, and to the 2005 Google Summer of
2001 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002002
Tim Petersc7605f22006-04-17 21:12:33 +00002003- The ``__del__`` method of class ``local`` in module ``_threading_local``
2004 returned before accomplishing any of its intended cleanup.
2005
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002006- Patch #790710: Add breakpoint command lists in pdb.

Anthony Baxtere29002c2006-04-12 12:07:31 +00002012- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
2013 Windows. Bug #1469163.
2014
Phillip J. Eby47032112006-04-11 01:07:43 +00002015- The warnings, linecache, inspect, traceback, site, and doctest modules
2016 were updated to work correctly with modules imported from zipfiles or
2017 via other PEP 302 __loader__ objects.

Martin v. Löwis4be4e652006-04-17 19:25:49 +00002032- The Makefile now has a reindent target, which runs reindent.py on
2033 the library.

Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002041 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002042 CXX from --with-cxx-main, see description in README.
2043

2047
Tim Peters8931ff12006-05-13 23:28:20 +00002048- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2049 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,

2054
Nick Coghlanda2268f2006-04-24 04:37:15 +00002055- test_contextlib now checks contextlib.nested can cope with exceptions
2056 being raised and caught inside exit handlers.
2057
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002058- test_cmd_line now checks operation of the -m and -c command switches
2059
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002060- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2061 it separately and by hand. It also wasn't cleaning up its changes to
2062 the current Decimal context.
2063
Thomas Woutersabd08882006-04-26 15:53:30 +00002064- regrtest.py now has a -M option to run tests that test the new limits of
2065 containers, on 64-bit architectures. Running these tests is only sensible
2066 on 64-bit machines with more than two gigabytes of memory. The argument
2067 passed is the maximum amount of memory for the tests to use.

Nick Coghlanc195d8a2006-04-24 03:04:43 +00002080- PEP 343: Added Context Types section to the library reference
2081 and attempted to bring other PEP 343 related documentation into
2082 line with the implementation and/or python-dev discussions.
2083
Tim Peters8dc73d22006-04-24 02:03:16 +00002084- Bug #1337990: clarified that ``doctest`` does not support examples
2085 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002088What's New in Python 2.5 alpha 1?
2089=================================
2090
Anthony Baxterebed3f62006-04-03 15:03:44 +00002091*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002092
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002093Core and builtins
2094-----------------
2095
Nick Coghlan43832302006-04-23 17:04:07 +00002096- PEP 338: -m command line switch now delegates to runpy.run_module
2097 allowing it to support modules in packages and zipfiles
2098
Martin v. Löwisc661b882006-04-20 04:54:23 +00002099- On Windows, .DLL is not an accepted file name extension for
2100 extension modules anymore; extensions are only found if they
2101 end in .PYD.
2102
Martin v. Löwisea62d252006-04-03 10:56:49 +00002103- Bug #1421664: sys.stderr.encoding is now set to the same value as
2104 sys.stdout.encoding.
2105
Neal Norwitz92e212f2006-04-03 04:48:37 +00002106- __import__ accepts keyword arguments.
2107
Georg Brandlccadf842006-03-31 18:54:53 +00002108- Patch #1460496: round() now accepts keyword arguments.
2109
Anthony Baxter262c00a2006-03-30 10:53:17 +00002110- Fixed bug #1459029 - unicode reprs were double-escaped.
2111
Hye-Shik Changd478f342006-03-23 12:32:36 +00002112- Patch #1396919: The system scope threads are reenabled on FreeBSD
2113 5.4 and later versions.
2114
Neal Norwitze98ccf62006-03-23 05:39:47 +00002115- Bug #1115379: Compiling a Unicode string with an encoding declaration
2116 now gives a SyntaxError.
2117
Georg Brandlabd1ff82006-03-18 07:59:59 +00002118- Previously, Python code had no easy way to access the contents of a
2119 cell object. Now, a ``cell_contents`` attribute has been added
2120 (closes patch #1170323).
2121
Tim Peterscf79aac2006-03-16 01:14:46 +00002122- Patch #1123430: Python's small-object allocator now returns an arena to
2123 the system ``free()`` when all memory within an arena becomes unused
2124 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2125 freed. Some applications will see a drop in virtual memory size now,
2126 especially long-running applications that, from time to time, temporarily
2127 use a large number of small objects. Note that when Python returns an
2128 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002129 platform C library will in turn return that memory to the operating system.
2130 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002131 appears to be effective at least on Microsoft C and gcc-based systems.
2132 Thanks to Evan Jones for hard work and patience.
2133
Georg Brandl533ff6f2006-03-08 18:09:27 +00002134- Patch #1434038: property() now uses the getter's docstring if there is
2135 no "doc" argument given. This makes it possible to legitimately use
2136 property() as a decorator to produce a read-only property.
2137
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002138- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2139 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2140 of requiring an int or long in slicing and a few other contexts, enabling
2141 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2142
Neal Norwitz995acdf2006-03-07 05:01:00 +00002143- Fixed various bugs reported by Coverity's Prevent tool.
2144
Brett Cannonbf364092006-03-01 04:25:17 +00002145- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2146 new exception base class, BaseException, which has a new message attribute.
2147 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2148 Raising a string exception now raises a DeprecationWarning.
2149
Thomas Woutersfb609f42006-02-28 16:37:25 +00002150- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2151 explicitly relative, using 'from .module import name' to mean 'from the same
2152 package as this module is in. Imports without dots still default to the
2153 old relative-then-absolute, unless 'from __future__ import
2154 absolute_import' is used.
2155
Brett Cannona7446e32006-02-27 23:39:10 +00002156- Properly check if 'warnings' raises an exception (usually when a filter set
2157 to "error" is triggered) when raising a warning for raising string
2158 exceptions.
2159
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002160- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002161 The name was removed from Include/code.h.
2162
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002163- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002164
Guido van Rossum1968ad32006-02-25 22:38:04 +00002165- Patch 1433928:
2166 - The copy module now "copies" function objects (as atomic objects).
2167 - dict.__getitem__ now looks for a __missing__ hook before raising
2168 KeyError.
2169
Tim Peters84ef21c2006-02-28 20:39:06 +00002170- PEP 343: with statement implemented. Needs ``from __future__ import
2171 with_statement``. Use of 'with' as a variable will generate a warning.
2172 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002173 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002174 The following objects have __context__ methods:
2175 - The built-in file type.
2176 - The thread.LockType type.
2177 - The following types defined by the threading module:
2178 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2179 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002180
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002181- Fix the encodings package codec search function to only search
2182 inside its own package. Fixes problem reported in patch #1433198.
2183
2184 Note: Codec packages should implement and register their own
2185 codec search function. PEP 100 has the details.
2186
Tim Peters9ea89d22006-06-04 03:26:02 +00002187- PEP 353: Using ``Py_ssize_t`` as the index type.
2188
2189- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2190 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2191 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2192 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2193 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002194
Neal Norwitzfc76d632006-01-10 06:03:13 +00002195- Patch #1400181, fix unicode string formatting to not use the locale.
2196 This is how string objects work. u'%f' could use , instead of .
2197 for the decimal point. Now both strings and unicode always use periods.
2198
Neal Norwitz671b9e32006-01-09 07:07:12 +00002199- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2200 configure would break checking curses.h.
2201
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002202- Bug #959576: The pwd module is now builtin. This allows Python to be
2203 built on UNIX platforms without $HOME set.
2204
Neal Norwitzc10978f2005-12-19 06:07:16 +00002205- Bug #1072182, fix some potential problems if characters are signed.
2206
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002207- Bug #889500, fix line number on SyntaxWarning for global declarations.
2208
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002209- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2210
Neal Norwitze7214a12005-12-18 05:03:17 +00002211- Support for converting hex strings to floats no longer works.
2212 This was not portable. float('0x3') now raises a ValueError.
2213
Barry Warsaw2a38a862005-12-18 01:27:35 +00002214- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002215 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002216 is now displayed in interactive prompt banner.
2217
Georg Brandlfa166682005-12-17 21:45:17 +00002218- Implementation of PEP 341 - Unification of try/except and try/finally.
2219 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002220 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002221
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002222- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2223 now encodes backslash correctly.
2224
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002225- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2226
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002227- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002228 and long longs.
2229
Neal Norwitz67715f02005-11-09 06:59:35 +00002230- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002231 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002232 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002233
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002234- Replaced most Unicode charmap codecs with new ones using the
2235 new Unicode translate string feature in the builtin charmap
2236 codec; the codecs were created from the mapping tables available
2237 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2238 encodings now include a mapping for the Apple logo)
2239
Tim Peterse3547fd2005-12-16 23:13:57 +00002240- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002241
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002242- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002243
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002244- A new AST parser implementation was completed. The abstract
2245 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002246 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002247
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002248- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002249 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2250
Neal Norwitz708e51a2005-10-03 04:48:15 +00002251- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2252
Neal Norwitz11bd1192005-10-03 00:54:56 +00002253- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2254 Provide a warning when a directory is passed on the command line.
2255
Neal Norwitz40d37812005-10-02 01:48:49 +00002256- Fix segfault with invalid coding.
2257
2258- SF bug #772896: unknown encoding results in MemoryError.
2259
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002260- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002261 supported a __len__() method which evaluated to False when the iterator
2262 was empty.
2263
Guido van Rossum630db602005-09-20 18:49:54 +00002264- On 64-bit platforms, when __len__() returns a value that cannot be
2265 represented as a C int, raise OverflowError.
2266
Skip Montanarof8948ca2005-09-19 03:54:46 +00002267- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002268 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002269
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002270- SF bug #893549: parsing keyword arguments was broken with a few format
2271 codes.
2272
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002273- Changes donated by Elemental Security to make it work on AIX 5.3
2274 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2275 bug #105470: test_pwd fails on 64bit system (Opteron).
2276
Guido van Rossum539c6622005-09-14 17:49:54 +00002277- Changes donated by Elemental Security to make it work on HP-UX 11 on
2278 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2279
Georg Brandl4550b8d2005-08-26 06:43:52 +00002280- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002281 (fixes bug #1119418).
2282
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002283- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2284
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002285- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2286 exceptions that cause a function to exit.
2287
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002288- The implementation of set() and frozenset() was revised to use its
2289 own internal data structure. Memory consumption is reduced by 1/3
2290 and there are modest speed-ups as well. The API is unchanged.
2291
Tim Petersde7990b2005-07-17 23:45:23 +00002292- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2293
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002294- SF bug #1229429: PyObject_CallMethod failed to decrement some
2295 reference counts in some error exit cases.
2296
Tim Petersecc6e6a2005-07-10 22:30:55 +00002297- SF bug #1185883: Python's small-object memory allocator took over
2298 a block managed by the platform C library whenever a realloc specified
2299 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002300 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002301 portable way to copy data from the C-managed block into Python's
2302 small-object space without risking a memory fault. Python's small-object
2303 realloc now leaves such blocks under the control of the platform C
2304 realloc.
2305
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002306- SF bug #1232517: An overflow error was not detected properly when
2307 attempting to convert a large float to an int in os.utime().
2308
Raymond Hettinger3296e692005-06-29 23:29:56 +00002309- SF bug #1224347: hex longs now print with lowercase letters just
2310 like their int counterparts.
2311
Michael W. Hudson188d4362005-06-20 16:52:57 +00002312- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2313 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2314 interpreter states; back out that fix and do a better job (see
2315 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2316 for a longer write-up of the problem).
2317
Michael W. Hudsondf888462005-06-03 14:41:55 +00002318- SF patch #1180995: marshal now uses a binary format by default when
2319 serializing floats.
2320
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002321- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2322 the routines that promise to produce IEEE 754 binary representations
2323 of floats now simply copy bytes around.
2324
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002325- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2326 278.
2327
Brett Cannonc3647ac2005-04-26 03:45:26 +00002328- patch #1109424: int, long, float, complex, and unicode now check for the
2329 proper magic slot for type conversions when subclassed. Previously the
2330 magic slot was ignored during conversion. Semantics now match the way
2331 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002332 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002333 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002334 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002335
Barry Warsawc8d907c2005-04-19 23:43:40 +00002336- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2337 NULL, now raise an AttributeError when attempting to set or delete the
2338 attribute. Previously a TypeError was raised, but this was inconsistent
2339 with the equivalent pure-Python implementation.
2340
Michael W. Hudson774479c2005-04-18 08:46:17 +00002341- It is now safe to call PyGILState_Release() before
2342 PyEval_InitThreads() (note that if there is reason to believe there
2343 are multiple threads around you still must call PyEval_InitThreads()
2344 before using the Python API; this fix is for extension modules that

Georg Brandl828fdef2006-04-01 08:59:03 +00002613 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002614 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002615 module will not be built.
2616
Tim Petersc17976e2006-04-01 00:26:53 +00002617- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2618 aren't officially supported here, and trying to use them will probably
2619 raise an exception some day. But dicts have been allowed, and "mostly
2620 worked", so support for them won't go away without warning.
2621
Georg Brandl338ef7d2006-03-31 18:42:16 +00002622- Bug #1445068: getpass.getpass() can now be given an explicit stream
2623 argument to specify where to write the prompt.
2624
Georg Brandl22ec80b2006-03-31 18:25:44 +00002625- Patch #1462313, bug #1443328: the pickle modules now can handle classes
2626 that have __private names in their __slots__.
2627

2631 key to be used for signing the uploaded code.
2632
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002633- Queue.Queue objects now support .task_done() and .join() methods
2634 to make it easier to monitor when daemon threads have completed
2635 processing all enqueued tasks. Patch #1455676.
2636
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002637- popen2.Popen objects now preserve the command in a .cmd attribute.
2638
Thomas Hellerc61c0492006-03-22 10:09:27 +00002639- Added the ctypes ffi package.
2640
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002641- email 4.0 package now integrated. This is largely the same as the email 3.0
2642 package that was included in Python 2.3, except that PEP 8 module names are
2643 now used (e.g. mail.message instead of email.Message). The MIME classes
2644 have been moved to a subpackage (e.g. email.mime.text instead of
2645 email.MIMEText). The old names are still supported for now. Several
2646 deprecated Message methods have been removed and lots of bugs have been
2647 fixed. More details can be found in the email package documentation.
2648
Walter Dörwald40108c92006-03-27 08:15:44 +00002649- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2650 (a subclass of tuple) that provides incremental decoders and encoders
2651 (a way to use stateful codecs without the stream API). Python functions
2652 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2653 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2654 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002655
Walter Dörwald067db482006-03-15 22:17:27 +00002656- Patch #1359365: Calling next() on a closed StringIO.String object raises
2657 a ValueError instead of a StopIteration now (like file and cString.String do).
2658 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2659 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002660
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002661- A regrtest option -w was added to re-run failed tests in verbose mode.

2664 interpreter to exit.
2665
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002666- The function get_count() has been added to the gc module, and gc.collect()
2667 grew an optional 'generation' argument.
2668
Martin v. Löwisfbab90e2006-03-05 13:36:04 +00002669- A library msilib to generate Windows Installer files, and a distutils
2670 command bdist_msi have been added.
2671
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002672- PEP 343: new module contextlib.py defines decorator @contextmanager
2673 and helpful context managers nested() and closing().
2674
Martin v. Löwis415ed932006-02-27 19:56:30 +00002675- The compiler package now supports future imports after the module docstring.

2681 be used to control how files are opened.
2682
Georg Brandlc029f872006-02-19 14:12:34 +00002683- Patch #1212287: fileinput.input() now has a mode parameter for

2729 LoadError as documented, instead of IOError. For compatibility,
2730 LoadError subclasses IOError.
2731

Tim Peterse3547fd2005-12-16 23:13:57 +00002733 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2734 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2735 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2736 Ronald L. Rivest offered this advice for Python:
2737
2738 "The consensus of researchers in this area (at least as
2739 expressed at the NIST Hash Function Workshop 10/31/05),
2740 is that SHA-256 is a good choice for the time being, but
2741 that research should continue, and other alternatives may
2742 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002743
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002744- Added a subset of Fredrik Lundh's ElementTree package. Available

2797 even if there is an exception in later lines, resulting in
Walter Dörwalda05834e2005-10-09 19:38:21 +00002798 correct line numbers for decoding errors in source code.
Martin v. Löwis56066d22005-08-24 07:38:12 +00002799

2815 parameter, but uses the usual "kwargs=None".
2816
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002817- textwrap now processes text chunks at O(n) speed instead of O(n**2).

2837 Bug #1224621.
2838
Raymond Hettinger68c04532005-06-10 11:05:19 +00002839- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002840 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002841 the generate_tokens() function now accepts a callable argument that
2842 terminates by raising StopIteration.
2843
Georg Brandl9166e1a2005-06-04 09:20:03 +00002844- Bug #1196315: fix weakref.WeakValueDictionary constructor.

2847 component of the path.
2848
Skip Montanaro174dd222005-05-14 20:54:16 +00002849- Patch #1120353: The xmlrpclib module provides better, more transparent,

2852 class at all.
2853
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002854- distutils.commands.upload was added to support uploading distribution

2861 instead of raising a TypeError when interacting with other types. This
2862 allows other classes to implement __radd__ style methods and have them
2863 work as expected.
2864
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002865- Bug #1163325: Decimal infinities failed to hash. Attempting to

Martin v. Löwisa4dac402005-03-03 11:39:45 +00002880 profile.py if available.
2881
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00002882- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
2883

2890
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00002891- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
2892

2894
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00002895- Patch #1104111: Alter setup.py --help and --help-commands.
2896
Martin v. Löwis4afe1542005-03-01 08:09:28 +00002897- Patch #1121234: Properly cleanup _exit and tkerror commands.
2898
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00002899- Patch #1049151: xdrlib now unpacks booleans as True or False.
2900
Raymond Hettingerbab41432005-02-05 01:31:19 +00002901- Fixed bug in a NameError bug in cookielib. Patch #1116583.
2902
Guido van Rossumd0641422005-02-03 15:01:24 +00002903- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2904 disables recursive traversal through instance attributes, which can
2905 be exploited in various ways.
2906
Tim Peterse3547fd2005-12-16 23:13:57 +00002907- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002908 flags on the HTTP listening socket.
2909
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002910- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2911 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2912
Fred Drakefbdeaad2006-07-29 16:56:15 +00002913- Patches #893642, #1039083: add allow_none, encoding arguments to
2914 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002915
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002916- Bug #1110478: Revert os.environ.update to do putenv again.
2917
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002918- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2919
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002920- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2921
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002922- Enhancements to the csv module:
2923
2924 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002925 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002926 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002927 + Dialect parameter parsing has been re-implemented to improve error
2928 reporting.
2929 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2930 dictates.
2931 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002932 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002933 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002934 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2935 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002936 + reader now allows \r characters to be quoted (previously it only allowed
2937 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002938 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002939 + Dialect classes passed to the module are no longer instantiated by
2940 the module before being parsed (the former validation scheme required
2941 this, but the mechanism was unreliable).
2942 + The dialect registry now contains instances of the internal
2943 C-coded dialect type, rather than references to python objects.
2944 + the internal c-coded dialect type is now immutable.
2945 + register_dialect now accepts the same keyword dialect specifications
2946 as the reader and writer, allowing the user to register dialects
2947 without first creating a dialect class.
2948 + a configurable limit to the size of parsed fields has been added -
2949 previously, an unmatched quote character could result in the entire
2950 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00002951 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002952 the parser field size limit (returning the former limit). The initial
2953 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00002954 + A line_num attribute has been added to the reader object, which tracks
2955 the number of lines read from the source iterator. This is not
2956 the same as the number of records returned, as records can span
2957 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002958 + reader and writer objects were not being registered with the cyclic-GC.
2959 This has been fixed.
2960
Brett Cannone6539c42005-01-08 02:43:53 +00002961- _DummyThread objects in the threading module now delete self.__block that is
2962 inherited from _Thread since it uses up a lock allocated by 'thread'. The
2963 lock primitives tend to be limited in number and thus should not be wasted on
2964 a _DummyThread object. Fixes bug #1089632.
2965
Raymond Hettinger97db05d2005-01-07 08:15:41 +00002966- The imghdr module now detects Exif files.
2967
Raymond Hettinger6065d322004-12-20 23:51:53 +00002968- StringIO.truncate() now correctly adjusts the size attribute.
2969 (Bug #951915).
2970
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002971- locale.py now uses an updated locale alias table (built using
2972 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
2973 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002974 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00002975
Raymond Hettinger3557f422004-12-07 12:02:02 +00002976- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
2977
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002978- the pickle module no longer accepts the deprecated None option in the
2979 args tuple returned by __reduce__().
2980
Brett Cannon84667c02004-12-07 03:25:18 +00002981- optparse now optionally imports gettext. This allows its use in setup.py.
2982
Raymond Hettinger3489cad2004-12-05 05:20:42 +00002983- the pickle module no longer uses the deprecated bin parameter.
2984
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00002985- the shelve module no longer uses the deprecated binary parameter.
2986
Raymond Hettinger6c92d762004-12-05 03:28:00 +00002987- the pstats module no longer uses the deprecated ignore() method.
2988
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00002989- the filecmp module no longer uses the deprecated use_statcache argument.
2990
Raymond Hettinger664347b2004-12-04 21:21:53 +00002991- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
2992 extended or overridden by subclasses. Formerly, the subclassed method would
2993 be ignored by the rest of the module. (Bug #1078905).
2994
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002995- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002996 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002997
Walter Dörwald36733692004-12-22 12:50:50 +00002998- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
2999 once when a size argument is given. This prevents a buffer overflow in the
3000 tokenizer with very long source lines.
3001
Barry Warsaw538561e2006-01-01 21:48:54 +00003002- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3003 immediately after creating the object, without any intervening
3004 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003005
Skip Montanaro05885812005-01-16 20:48:27 +00003006- The reconvert.quote function can now emit triple-quoted strings. The
3007 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003008
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003009- ``UserString.MutableString`` now supports negative indices in
3010 ``__setitem__`` and ``__delitem__``
3011
Greg Ward40407942005-03-05 02:53:17 +00003012- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3013 correctly.
3014
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003015- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3016 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3017 character even if the user has passed a size parameter to get a proper
3018 line ending. Remove the special handling of a "\r\n" that has been split
3019 between two lines.
3020
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003021- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3022 about illegal code points. The codec now supports PEP 293 style error
3023 handlers.
3024
Walter Dörwald78a78b02005-09-01 12:04:29 +00003025- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003026 from the input stream, so that the output is a byte string in the correct
3027 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003028
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003029- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3030 considering it exactly like a '*'.
3031
Walter Dörwald007f8df2005-10-09 19:42:27 +00003032- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3033 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003034
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003035- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3036
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003037- Patch #1413711: Certain patterns of differences were making difflib
3038 touch the recursion limit.
3039
Walter Dörwald58917a62006-03-31 15:26:22 +00003040- Bug #947906: An object oriented interface has been added to the calendar
3041 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003042 called as a script (e.g. via ``python -mcalendar``). Localized month and
3043 weekday names can be ouput (even if an exotic encoding is used) using
3044 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003045
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003046Build
3047-----
3048
Neal Norwitz602d3392006-03-31 08:21:40 +00003049- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3050 by using -mieee gcc option.
3051
Martin v. Löwis86d66262006-02-17 08:40:11 +00003052- Patch #1432345: Make python compile on DragonFly.
3053
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003054- Build support for Win64-AMD64 was added.
3055
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003056- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3057
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003058- Patch #881820: look for openpty and forkpty also in libbsd.
3059
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003060- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3061 The zlib module is now builtin on Windows.
3062
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003063- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3064
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003065- Bug #1189330: configure did not correctly determine the necessary
3066 value of LINKCC if python was built with GCC 4.0.
3067
Trent Mick8321b422005-07-26 02:29:21 +00003068- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3069 vulnerability in zlib 1.2.1 and 1.2.2.
3070
Brett Cannon08cd5982005-04-24 22:26:38 +00003071- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3072 flags that change binary compatibility. Changes were also made to
3073 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003074 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003075
Bob Ippolitoed233462005-03-29 13:47:59 +00003076- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3077 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3078 no longer exists). This configure patch makes things right.
3079
Martin v. Löwise2713be2005-03-08 15:03:08 +00003080- Bug #1158607: Build with --disable-unicode again.
3081
Brett Cannon46d96232005-02-16 00:07:19 +00003082- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3083 defined. Discovered as a result of not being able to build on OS X.
3084
Brett Cannon516592f2004-12-07 00:42:59 +00003085- setup.py now uses the directories specified in LDFLAGS using the -L option
3086 and in CPPFLAGS using the -I option for adding library and include
3087 directories, respectively, for compiling extension modules against. This has
3088 led to the core being compiled using the values in CPPFLAGS. It also removes
3089 the need for the special-casing of both DarwinPorts and Fink for darwin since
3090 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3091 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3092 Fink, ``-I/opt/local/include`` for DarwinPorts).
3093
Brett Cannon43802422005-02-10 20:48:03 +00003094- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3095 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3096 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3097 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003099C API
3100-----
3101
Tim Petersc9d78aa2006-03-26 23:27:58 +00003102- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3103 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3104 is obtained via the ``PyObject_`` family, it must be released via the
3105 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3106 always been officially true, but when Python's small-object allocator was
3107 introduced, an attempt was made to cater to a few extension modules
3108 discovered at the time that obtained memory via ``PyObject_New`` but
3109 released it via ``PyMem_DEL``. It's years later, and if such code still
3110 exists it will fail now (probably with segfaults, but calling wrong
3111 low-level memory management functions can yield many symptoms).
3112
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003113- Added a C API for set and frozenset objects.
3114
Raymond Hettinger66517482004-12-03 11:45:13 +00003115- Removed PyRange_New().
3116
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003117- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3118 mapping argument now. This string is used as a mapping table. Byte values
3119 greater than the length of the string and 0xFFFE are treated as undefined
3120 mappings.
