Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +000014
Guido van Rossumaa975432008-04-10 22:43:58 +000015- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
16 having a self-referential tuple, which is possible from C code. Nor did
17 object's tp_str consider that a type's tp_str could do something that could
18 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
19 respectively, fixed the issues. (Backport of r58288 from trunk.)
20
Georg Brandld9f1da02008-03-29 01:50:46 +000021- Patch #1442: properly report exceptions when the PYTHONSTARTUP file
22 cannot be executed.
23
Amaury Forgeot d'Arc8432d862008-03-28 20:45:42 +000024- The compilation of a class nested in another class used to leak one
25 reference on the outer class name.
26
Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +000027- Issue #1477: With narrow Unicode builds, the unicode escape sequence
28 \Uxxxxxxxx did not accept values outside the Basic Multilingual Plane. This
29 affected raw unicode literals and the 'raw-unicode-escape' codec. Now
30 UTF-16 surrogates are generated in this case, like normal unicode literals
31 and the 'unicode-escape' codec.
32
Neal Norwitzb3635f92008-03-18 04:17:36 +000033- Issue #2321: use pymalloc for unicode object string data to reduce
34 memory usage in some circumstances.
Andrew M. Kuchlingbe0adfc2008-02-23 17:18:19 +000035
Sean Reifscheider4af861c2008-03-20 17:39:31 +000036- Issue #2238: Some syntax errors in *args and **kwargs expressions could give
37 bogus error messages.
38
Gregory P. Smith14acde32008-04-09 23:41:13 +000039- Issue #2587: In the C API, PyString_FromStringAndSize() takes a signed size
40 parameter but was not verifying that it was greater than zero. Values
41 less than zero will now raise a SystemError and return NULL to indicate a
42 bug in the calling C code.
43
Gregory P. Smith9aa040d2008-06-02 00:07:25 +000044- Issue #2588, #2589: Fix potential integer underflow and overflow
45 conditions in the PyOS_vsnprintf C API function.

52 reference to themselves.
53
Amaury Forgeot d'Arc8d904c32008-04-22 21:17:18 +000054- Issue #2670: Fix a failure in urllib2.build_opener(), when passed two
55 handlers that derive the same default base class.
56
Amaury Forgeot d'Arc198e3532008-03-27 23:41:59 +000057- Issue #2495: tokenize.untokenize now inserts a space between two consecutive
58 string literals; previously, ["" ""] was rendered as [""""], which is
59 incorrect python code.
60
Mark Dickinsonbfdbfd42008-03-25 18:58:13 +000061- Issue #2482: Make sure that the coefficient of a Decimal is always
62 stored as a str instance, not as a unicode instance. This ensures
63 that str(Decimal) is always an instance of str. This fixes a
64 regression from Python 2.5.1 to Python 2.5.2.
65
Mark Dickinson26c25d92008-03-25 14:35:25 +000066- Issue #2478: fix failure of decimal.Decimal(0).sqrt()
67

69 advertised in the docs.
70

77 root directory, and also exclude .hg, .git, .bzr, and _darcs.
78
Andrew M. Kuchling37d4f7b2008-02-23 19:06:54 +000079- Bug #1389051: imaplib causes excessive memory fragmentation when reading
80 large messages.
81
Andrew M. Kuchling664553a2008-02-23 19:30:59 +000082- Bug #1389051, 1092502: fix excessively large memory allocations when
83 calling .read() on a socket object wrapped with makefile().
84
Andrew M. Kuchling05a19a52008-02-23 17:21:44 +000085- Bug #1433694: minidom's .normalize() failed to set .nextSibling for
86 last child element.
87
Gregory P. Smith26660402008-06-01 23:44:46 +000088- Issue #2791: subprocess.Popen.communicate explicitly closes its
89 stdout and stderr fds rather than leaving them open until the
90 instance is destroyed.

142-----------------
143
Martin v. Löwis73c01d42008-02-14 11:26:18 +0000144- Added checks for integer overflows, contributed by Google. Some are
145 only available if asserts are left in the code, in cases where they

971
Neal Norwitz0bcafac2006-09-11 08:51:17 +0000972- Make _PyGILState_NoteThreadState() static, it was not used anywhere
973 outside of pystate.c and should not be necessary.
974
Brett Cannon19d76c52006-09-09 07:18:44 +0000975- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
976 allows calling unicode() on exceptions classes directly to succeed.
977
Georg Brandlecab6232006-09-06 06:47:02 +0000978- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
979 Also make sure that every exception class has __module__ set to
980 'exceptions'.
981
Georg Brandl37a9e572006-09-06 06:09:34 +0000982- Bug #1550983: emit better error messages for erroneous relative

992
Neal Norwitz29a5fdb2006-09-05 02:21:38 +0000993- The return tuple from str.rpartition(sep) is (tail, sep, head) where
994 head is the original string if sep was not found.
995
Neal Norwitz3b3aae02006-09-05 03:56:01 +0000996- Bug #1520864: unpacking singleton tuples in list comprehensions and
997 generator expressions (x for x, in ... ) works again. Fixing this problem
998 required changing the .pyc magic number. This means that .pyc files
999 generated before 2.5c2 will be regenerated.

Neal Norwitz24b6f202006-09-05 04:43:56 +00001114- Fix infinite recursion when subclassing long and overriding __hash__.
1115
1116- Fix concatenation (+=) of long strings.
1117
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001118- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001119 compared equal or unequal to a string and a UnicodeDecodeError
1120 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001121
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001122 Instead, the equal (==) and unequal (!=) comparison operators will
1123 now issue a UnicodeWarning and interpret the two objects as
1124 unequal. The UnicodeWarning can be filtered as desired using
1125 the warning framework, e.g. silenced completely, turned into an
1126 exception, logged, etc.
1127
1128 Note that compare operators other than equal and unequal will still
1129 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001130
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001131- Fix segfault when doing string formatting on subclasses of long.
1132
1133- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1134 with new-style classes.
1135
1136- Fix bug related to __len__ functions returning negative values with
1137 classic classes.
1138
1139- Patch #1538606, Fix __index__() clipping. There were some problems
1140 discovered with the API and how integers that didn't fit into Py_ssize_t
1141 were handled. This patch attempts to provide enough alternatives
1142 to effectively use __index__.
1143
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001144- Bug #1536021: __hash__ may now return long int; the final hash
1145 value is obtained by invoking hash on the long int.
1146
Thomas Hellerab1049c2006-08-08 17:37:00 +00001147- Bug #1536786: buffer comparison could emit a RuntimeWarning.

1150 sys.stdin is closed.
1151
Thomas Heller74d36f02006-08-04 18:17:40 +00001152- On Windows, the PyErr_Warn function is now exported from
1153 the Python dll again.
1154
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001155- Bug #1191458: tracing over for loops now produces a line event
1156 on each iteration. Fixing this problem required changing the .pyc
1157 magic number. This means that .pyc files generated before 2.5c1
1158 will be regenerated.
1159
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001160- Bug #1333982: string/number constants were inappropriately stored
1161 in the byte code and co_consts even if they were not used, ie
1162 immediately popped off the stack.
1163
Georg Brandle9462c72006-08-04 18:03:37 +00001164- Fixed a reference-counting problem in property().

1168-------
1169
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001170- Fix a bug in the ``compiler`` package that caused invalid code to be
1171 generated for generator expressions.
1172
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001173- The distutils version has been changed to 2.5.0. The change to
1174 keep it programmatically in sync with the Python version running
1175 the code (introduced in 2.5b3) has been reverted. It will continue
1176 to be maintained manually as static string literal.
1177
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001178- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001179 and this cannot be converted to the required C type, an exception is
1180 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001181 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001182
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001183- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001184 an exception.
1185
Tim Peterscbdd3502006-09-05 01:47:53 +00001186- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001187 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001188 workarounds for clocks with low resolution, to stop the code yielding

1205 str(exception) raised an exception.
1206
Neil Schemenauer06ded092006-08-04 16:20:30 +00001207- Fix a bug in the ``compiler`` package that caused invalid code to be

1220
Thomas Heller1ce433e2006-08-14 16:20:04 +00001221- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1222 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1223
Thomas Heller86720042006-08-14 11:17:48 +00001224- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1225 uses the _as_parameter_ attribute when objects are passed to foreign
1226 function calls. The ctypes version number was changed to 1.0.1.
1227
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001228- Bug #1530559, struct.pack raises TypeError where it used to convert.
1229 Passing float arguments to struct.pack when integers are expected
1230 now triggers a DeprecationWarning.

1254-----
1255
Martin v. Löwisa09fd6e2006-08-16 12:55:10 +00001256- Bug #1535502, build _hashlib on Windows, and use masm assembler
1257 code in OpenSSL.
1258
Thomas Hellerdb7b4432006-08-04 19:49:31 +00001259- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

Tim Peters4643c2f2006-08-10 22:45:34 +00001264C API
1265-----
1266
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001267- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1268
Tim Peters4643c2f2006-08-10 22:45:34 +00001269- Bug #1069160. Internal correctness changes were made to
1270 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1271 the documentation was changed to state that the return value
1272 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001275What's New in Python 2.5 beta 3?
1276================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001277
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001278*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001279
1280Core and builtins
1281-----------------
1282
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001283- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001284 returned a long (see PEP 353).
1285
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001286- Bug #1515471: string.replace() accepts character buffers again.
1287
Neal Norwitz07aadb12006-07-30 06:55:48 +00001288- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1289 This provides the proper warning for struct.pack().
1290 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1291
Neal Norwitz0d62a062006-07-30 06:53:31 +00001292- Patch #1531113: Fix augmented assignment with yield expressions.
1293 Also fix a SystemError when trying to assign to yield expressions.
1294
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001295- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1296 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1297 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1298 excessive filesystem operations during imports.
1299
Tim Petersbc24eee2006-07-27 01:14:53 +00001300- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1301 operations on signed longs that are formally undefined by C.
1302 Unfortunately, at least one compiler now cares about that, so complicated
1303 the code to make that compiler happy again.
1304
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001305- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1306
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001307- Patch #1232023: Stop including current directory in search
1308 path on Windows.
1309
Neal Norwitze1fdb322006-07-21 05:32:28 +00001310- Fix some potential crashes found with failmalloc.
1311
Neal Norwitze7563102006-07-17 01:00:16 +00001312- Fix warnings reported by Klocwork's static analysis tool.
1313
Neal Norwitz84be93b2006-07-16 01:50:38 +00001314- Bug #1512814, Fix incorrect lineno's when code within a function
1315 had more than 255 blank lines.
1316
Georg Brandl9dceedb2006-07-12 15:31:17 +00001317- Patch #1521179: Python now accepts the standard options ``--help`` and
1318 ``--version`` as well as ``/?`` on Windows.
1319
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001320- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001321 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001322 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001323
Tim Peters112aad32006-07-19 00:03:19 +00001324- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001325 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001326 new ``sys._current_frames()`` returns a dictionary with one entry,
1327 mapping the faux "thread id" 0 to the current frame.
1328
Ronald Oussoren3075e162006-07-25 20:28:55 +00001329- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001330
Ronald Oussoren3075e162006-07-25 20:28:55 +00001331
Neal Norwitza1f10902006-07-12 07:28:29 +00001332Library
1333-------
1334
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001335- Correction of patch #1455898: In the mbcs decoder, set final=False
1336 for stream decoder, but final=True for the decode function.
1337
Georg Brandl07fec3a2006-08-01 18:49:24 +00001338- os.urandom no longer masks unrelated exceptions like SystemExit or
1339 KeyboardInterrupt.
1340
Tim Peters4643c2f2006-08-10 22:45:34 +00001341- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001342 shutil.copytree on Windows
1343
Georg Brandle34ac7c2006-07-30 11:07:23 +00001344- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1345 refers to file descriptors, not file objects.
1346
Tim Peterscbdd3502006-09-05 01:47:53 +00001347- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001348 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001349 #1513611, and probably others.
1350
Georg Brandledd9b0d2006-07-29 09:33:26 +00001351- Bug #1441397: The compiler module now recognizes module and function
1352 docstrings correctly as it did in Python 2.4.
1353
Tim Peters6f681472006-07-27 23:44:37 +00001354- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1355 lost that tests are sorted by name before being run. This rarely
1356 matters for well-written tests, but can create baffling symptoms if
1357 side effects from one test to the next affect outcomes. ``DocTestFinder``
1358 has been changed to sort the list of tests it returns.
1359
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001360- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001361 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001362
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001363- Bug #978833: Really close underlying socket in _socketobject.close.
1364
Georg Brandldb232dc2006-08-20 13:15:43 +00001365- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1366 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001367
Georg Brandlcf0c1722006-07-26 07:23:32 +00001368- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1369 to recursive calls and call it with the failing package name.
1370
Martin v. Löwis0b483032006-07-25 09:53:12 +00001371- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1372
Georg Brandlc13c34c2006-07-24 14:09:56 +00001373- Patch #1515343: Fix printing of deprecated string exceptions with a
1374 value in the traceback module.
1375
Greg Ward48fae7a2006-07-23 16:05:51 +00001376- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1377
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001378- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1379
Brett Cannoncaebe222006-07-18 04:41:36 +00001380- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1381 argument tuple. For arguments where zero is illegal, the value is forced to
1382 the minimum value that is correct. This is to support an undocumented but
1383 common way people used to fill in inconsequential information in the time
1384 tuple pre-2.4.
1385
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001386- Patch #1220874: Update the binhex module for Mach-O.
1387
Barry Warsawb110bad2006-07-21 14:51:07 +00001388- The email package has improved RFC 2231 support, specifically for
1389 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1390 (name*0=<blah>) parameter continuations. This may change the types of
1391 values returned from email.message.Message.get_param() and friends.
1392 Specifically in some cases where non-encoded continuations were used,
1393 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1394 will just return the string (since non-encoded continuations don't have
1395 charset and language parts).
1396
1397 Also, whereas % values were decoded in all parameter continuations, they are
1398 now only decoded in encoded parameter parts.
1399
Ronald Oussoren3075e162006-07-25 20:28:55 +00001400- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1401
1402- Bug #1517996: IDLE now longer shows the default Tk menu when a
1403 path browser, class browser or debugger is the frontmost window on MacOS X
1404
Barry Warsaw00decd72006-07-27 23:43:15 +00001405- Patch #1520294: Support for getset and member descriptors in types.py,
1406 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1407 of an object against these built-in types and more importantly, for getting
1408 their docstrings printed in the interactive interpreter's help() function.
1409

1413
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001414- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1415 a socket operation on a socket with a timeout, the exception will be
1416 caught correctly. Previously, the exception was not caught.
1417
Thomas Heller1393d6a2006-07-28 21:43:20 +00001418- Patch #1529514: The _ctypes extension is now compiled on more
1419 openbsd target platforms.
1420
Tim Peters9cab5932006-07-28 00:30:00 +00001421- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1422 a memory leak, affecting pickles and deep copies.
1423
Tim Petersbc24eee2006-07-27 01:14:53 +00001424- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1426
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001427- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1428
Thomas Hellerce049a02006-07-14 17:51:14 +00001429- Patch #1521817: Index range checking on ctypes arrays containing
1430 exactly one element enabled again. This allows iterating over these
1431 arrays, without the need to check the array size before.
1432
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001433- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001434 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001435 /dev/null in certain cases; this is now fixed.
1436
Thomas Heller47d7a062006-07-12 08:43:47 +00001437- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1438 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001439
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001440- Because of a misspelled preprocessor symbol, ctypes was always
1441 compiled without thread support; this is now fixed.
1442
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001443- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1444 methods now allow their database parameter to be None as the
1445 sleepycat API allows.
1446
Matt Flemingec926502006-07-28 11:27:27 +00001447- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1448 bluetooth API compared with Linux and FreeBSD.

Brett Cannonf23ad3d2006-07-25 17:32:20 +00001450Tests
1451-----
1452
1453- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1454 how long the test file should take to play. Now accepts taking 2.93 secs
1455 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1456
Georg Brandl4793aa32006-07-28 18:31:39 +00001457- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1458 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1459 run via ``regrtest.py``. Now they do.

1469- PythonLauncher now works correctly when the path to the script contains
1470 characters that are treated specially by the shell (such as quotes).
1471
1472- Bug #1527397: PythonLauncher now launches scripts with the working directory
1473 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001474 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001475 expect.

1483Core and builtins
1484-----------------
1485
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001486- Bug #1441486: The literal representation of -(sys.maxint - 1)
1487 again evaluates to a int object, not a long.
1488
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001489- Bug #1501934: The scope of global variables that are locally assigned
1490 using augmented assignment is now correctly determined.
1491
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001492- Bug #927248: Recursive method-wrapper objects can now safely
1493 be released.
1494
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001495- Bug #1417699: Reject locale-specific decimal point in float()
1496 and atof().
1497
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001498- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1499 omit a default "error" argument for NULL pointer. This allows
1500 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001501
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001502- Bug #1519018: 'as' is now validated properly in import statements.
1503
Neal Norwitz28746ab2006-07-09 22:14:42 +00001504- On 64 bit systems, int literals that use less than 64 bits are
1505 now ints rather than longs.
1506
Neal Norwitzed657552006-07-10 00:04:44 +00001507- Bug #1512814, Fix incorrect lineno's when code at module scope
1508 started after line 256.
1509
Tim Peters32a83612006-07-10 21:08:24 +00001510- New function ``sys._current_frames()`` returns a dict mapping thread
1511 id to topmost thread stack frame. This is for expert use, and is
1512 especially useful for debugging application deadlocks. The functionality
1513 was previously available in Fazal Majid's ``threadframe`` extension
1514 module, but it wasn't possible to do this in a wholly threadsafe way from
1515 an extension.

1518-------
1519
Martin v. Löwis77621582006-07-30 13:27:31 +00001520- Bug #1257728: Mention Cygwin in distutils error message about a missing
1521 VS 2003.
1522
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001523- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1524
Tim Peters32a83612006-07-10 21:08:24 +00001525- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001526 environment variable to be set in order to the SDK environment
1527 for finding the compiler, include files, etc.
1528
Martin v. Löwis388a8c22006-07-06 19:28:03 +00001529- Bug #1515998: Properly generate logical ids for files in bdist_msi.
1530
Nick Coghlan2d792252006-07-06 13:47:18 +00001531- warnings.py now ignores ImportWarning by default
1532
Thomas Woutersadd19112006-07-05 11:03:49 +00001533- string.Template() now correctly handles tuple-values. Previously,
1534 multi-value tuples would raise an exception and single-value tuples would
1535 be treated as the value they contain, instead.
1536
Martin v. Löwisede77f52006-07-03 13:01:35 +00001537- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1538 even if some data are received.
1539
Martin v. Löwis45482392006-07-03 12:28:58 +00001540- Bug #1267547: Put proper recursive setup.py call into the
1541 spec file generated by bdist_rpm.
1542
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001543- Bug #1514693: Update turtle's heading when switching between
1544 degrees and radians.
1545
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001546- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001547 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001548
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001549- Bug #1514703: Only setup canvas window in turtle when the canvas
1550 is created.
1551
Martin v. Löwis7596e832006-07-01 15:33:37 +00001552- Bug #1513223: .close() of a _socketobj now releases the underlying

1556 attribute values.
1557
1558- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1559 sgmllib ('[' and ']' were not accepted).
1560
Georg Brandl1be63af2006-06-28 20:23:25 +00001561- Fix a bug in the turtle module's end_fill function.
1562
Brett Cannon53ab5b72006-06-22 16:49:14 +00001563- Bug #1510580: The 'warnings' module improperly required that a Warning
1564 category be either a types.ClassType and a subclass of Warning. The proper
1565 check is just that it is a subclass with Warning as the documentation states.
1566
Georg Brandlad29e632006-06-21 17:45:17 +00001567- The compiler module now correctly compiles the new try-except-finally
1568 statement (bug #1509132).
1569
Neal Norwitz60373cd2006-06-22 06:30:50 +00001570- The wsgiref package is now installed properly on Unix.
1571
Vinay Sajip28e57612006-07-01 10:45:20 +00001572- A bug was fixed in logging.config.fileConfig() which caused a crash on
1573 shutdown when fileConfig() was called multiple times.
1574
Gerhard Häring762fbd32006-07-02 17:48:30 +00001575- The sqlite3 module did cut off data from the SQLite database at the first
1576 null character before sending it to a custom converter. This has been fixed
1577 now.
1578
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001579Extension Modules
1580-----------------
1581
Tim Peters112aad32006-07-19 00:03:19 +00001582- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1583 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1584 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001585
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001586- Assigning None to pointer type fields in ctypes structures possible
1587 overwrote the wrong fields, this is fixed now.
1588
1589- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1590 on non-Windows platforms.
1591
1592- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1593 integer or long, without range checking.
1594
1595- Patch #1517790: It is now possible to use custom objects in the ctypes
1596 foreign function argtypes sequence as long as they provide a from_param
1597 method, no longer is it required that the object is a ctypes type.
1598
1599- The '_ctypes' extension module now works when Python is configured
1600 with the --without-threads option.
1601
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001602- Bug #1513646: os.access on Windows now correctly determines write
1603 access, again.
1604
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001605- Bug #1512695: cPickle.loads could crash if it was interrupted with
1606 a KeyboardInterrupt.
1607
Neal Norwitza12aa882006-07-06 06:45:08 +00001608- Bug #1296433: parsing XML with a non-default encoding and
1609 a CharacterDataHandler could crash the interpreter in pyexpat.
1610
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001611- Patch #1516912: improve Modules support for OpenVMS.

1615
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001616- Automate Windows build process for the Win64 SSL module.
1617
Tim Peters32a83612006-07-10 21:08:24 +00001618- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001619 Previously, the slight difference could cause compilation errors of the
1620 'zlib' module on systems with more than one version of zlib.
1621
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001622- The MSI compileall step was fixed to also support a TARGETDIR
1623 with spaces in it.
1624
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001625- Bug #1517388: sqlite3.dll is now installed on Windows independent
1626 of Tcl/Tk.
1627
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001628- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001629 trying to be installed even though it's empty.

Neal Norwitzb15ac312006-06-29 04:10:08 +00001631Tests
1632-----
1633
1634- Call os.waitpid() at the end of tests that spawn child processes in order
1635 to minimize resources (zombies).
1636
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001637Documentation
1638-------------
1639
Nick Coghlan2d792252006-07-06 13:47:18 +00001640- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1641 documentation for the warnings module.
1642
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001643- Patch #1509163: MS Toolkit Compiler no longer available.
1644

Nick Coghlanc649ec52006-05-29 12:43:05 +00001648What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +00001649================================
Anthony Baxter51bcb682006-04-05 14:51:42 +00001650
Anthony Baxterd1136802006-06-19 12:04:15 +00001651*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +00001652
1653Core and builtins
1654-----------------
1655
Georg Brandla56b9152006-06-19 06:35:54 +00001656- Patch #1507676: Error messages returned by invalid abstract object operations
1657 (such as iterating over an integer) have been improved and now include the
1658 type of the offending object to help with debugging.
1659
Brett Cannonea3912b2006-06-13 21:46:41 +00001660- Bug #992017: A classic class that defined a __coerce__() method that returned
1661 its arguments swapped would infinitely recurse and segfault the interpreter.
1662
Neal Norwitz909eb122006-06-12 02:13:21 +00001663- Fix the socket tests so they can be run concurrently.
1664
Neal Norwitzb9845e72006-06-12 02:11:18 +00001665- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001666 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001667
Brett Cannon22565aa2006-06-09 22:31:23 +00001668- Bug #532646: object.__call__() will continue looking for the __call__
1669 attribute on objects until one without one is found. This leads to recursion
1670 when you take a class and set its __call__ attribute to an instance of the
1671 class. Originally fixed for classic classes, but this fix is for new-style.
1672 Removes the infinite_rec_3 crasher.
1673
Georg Brandl24250812006-06-09 18:45:48 +00001674- The string and unicode methods startswith() and endswith() now accept
1675 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1676
Brett Cannonde3b0522006-06-08 17:00:45 +00001677- Buffer objects, at the C level, never used the char buffer
1678 implementation even when the char buffer for the wrapped object was
1679 explicitly requested (originally returned the read or write buffer).
1680 Now a TypeError is raised if the char buffer is not present but is
1681 requested.
1682
Georg Brandlddbaa662006-06-04 21:56:52 +00001683- Patch #1346214: Statements like "if 0: suite" are now again optimized
1684 away like they were in Python 2.4.
1685
Georg Brandlb7c8f542006-05-27 12:30:25 +00001686- Builtin exceptions are now full-blown new-style classes instead of
1687 instances pretending to be classes, which speeds up exception handling
1688 by about 80% in comparison to 2.5a2.
1689
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001690- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1691 Unicode 4.1.
1692
Georg Brandlf4ef1162006-05-26 18:03:31 +00001693- Patch #921466: sys.path_importer_cache is now used to cache valid and
1694 invalid file paths for the built-in import machinery which leads to
1695 fewer open calls on startup.
1696
Tim Peters696cf432006-05-24 21:10:40 +00001697- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1698 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1699 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1700 the number of input digits (it was and remains linear-time for bases
1701 2, 4, 8, 16 and 32).
1702
Tim Petersb713ec22006-05-23 18:45:30 +00001703- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1704 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1705 an integer close to ``sys.maxint``. This was repaired by patch
1706 #1335972, which also gives a nice speedup.
1707
Richard Jonescebbefc2006-05-23 18:28:17 +00001708- Patch #1337051: reduced size of frame objects.
1709
1710- PyErr_NewException now accepts a tuple of base classes as its
1711 "base" parameter.
1712
Richard Jones7c88dcc2006-05-23 10:37:38 +00001713- Patch #876206: function call speedup by retaining allocated frame
1714 objects.
1715
Georg Brandl7b90e162006-05-18 07:01:27 +00001716- Bug #1462152: file() now checks more thoroughly for invalid mode
1717 strings and removes a possible "U" before passing the mode to the
1718 C library function.
1719
Neal Norwitz1004a532006-05-15 07:17:23 +00001720- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1721
Neal Norwitz373f0a72006-05-15 07:04:36 +00001722- Bug #1487966: Fix SystemError with conditional expression in assignment
1723
Martin v. Löwis879768d2006-05-11 13:28:43 +00001724- WindowsError now has two error code attributes: errno, which carries
1725 the error values from errno.h, and winerror, which carries the error
1726 values from winerror.h. Previous versions put the winerror.h values
1727 (from GetLastError()) into the errno attribute.
1728
Martin v. Löwis77736712006-05-04 05:51:03 +00001729- Patch #1475845: Raise IndentationError for unexpected indent.
1730
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001731- Patch #1479181: split open() and file() from being aliases for each other.
1732
Tim Peters44bd9862006-06-01 13:49:23 +00001733- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1734 methods were always silently ignored by dictionaries when comparing keys.
1735 They are now passed through (except when using the C API function
1736 ``PyDict_GetItem()``, whose semantics did not change).
1737
1738- Bug #1456209: In some obscure cases it was possible for a class with a
1739 custom ``__eq__()`` method to confuse dict internals when class instances
1740 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1741 No, you don't have any code that did this ;-)

Trent Mick960a3f82006-06-28 20:30:41 +00001746- Bug #1295808: expat symbols should be namespaced in pyexpat
1747
1748- Patch #1462338: Upgrade pyexpat to expat 2.0.0
1749
Brett Cannon6ee7d012006-06-08 16:23:04 +00001750- Change binascii.hexlify to accept a read-only buffer instead of only a char
1751 buffer and actually follow its documentation.
1752
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001753- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1754
Nick Coghlanc649ec52006-05-29 12:43:05 +00001755- Patch #1478788 (modified version): The functional extension module has
1756 been renamed to _functools and a functools Python wrapper module added.
1757 This provides a home for additional function related utilities that are
1758 not specifically about functional programming. See PEP 309.
1759
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001760- Patch #1493701: performance enhancements for struct module.

1763
Georg Brandl8d3342b2006-05-16 07:38:27 +00001764- Patch #1435422: zlib's compress and decompress objects now have a
1765 copy() method.
1766
Andrew MacIntyre92913322006-06-13 15:04:24 +00001767- Patch #1454481: thread stack size is now tunable at runtime for thread
1768 enabled builds on Windows and systems with Posix threads support.
1769
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001770- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1771 (up to the system limit of 32K characters).
1772
1773- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1774 As a result, these functions now raise WindowsError instead of OSError.
1775
Tim Peters7a822da2006-05-25 21:50:17 +00001776- ``time.clock()`` on Win64 should use the high-performance Windows
1777 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1778 Windows platforms).
1779
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001780- Calling Tk_Init twice is refused if the first call failed as that
1781 may deadlock.
1782
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001783- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1784 accept it without potentially using an uninitialized pointer.
1785
1786- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1787 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1788 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00001789
Gregory P. Smith372b5832006-06-05 18:48:21 +00001790- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00001791 [pybsddb project SF patch number 1466734]
1792
Gregory P. Smith372b5832006-06-05 18:48:21 +00001793- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
1794 parameter is supplied. [SF pybsddb bug #1477863]
1795
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001796- bsddb: the __len__ method of a DB object has been fixed to return correct
1797 results. It could previously incorrectly return 0 in some cases.
1798 Fixes SF bug 1493322 (pybsddb bug 1184012).
1799
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001800- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1801 aborts the db transaction safely when a modifier callback fails.
1802 Fixes SF python patch/bug #1408584.
1803
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001804- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001805 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001806 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1807 database calls that would previously deadlock. [SF python bug #775414]
1808
Vinay Sajip28e57612006-07-01 10:45:20 +00001809- Patch #1446489: add support for the ZIP64 extensions to zipfile.

1831 mime.types file for determining MIME types.
1832
Georg Brandl2605ca82006-06-14 06:08:31 +00001833- Bug #1339007: Shelf objects now don't raise an exception in their
1834 __del__ method when initialization failed.
1835
Martin v. Löwisd8251432006-06-14 05:21:04 +00001836- Patch #1455898: The MBCS codec now supports the incremental mode for
1837 double-byte encodings.
1838
Tim Peters43898b42006-06-14 04:09:25 +00001839- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
1840 guarantee that adjacent triples in the return list always describe
1841 non-adjacent blocks. Previously, a pair of matching blocks could end
1842 up being described by multiple adjacent triples that formed a partition
1843 of the matching pair.
1844
Greg Ward0e0c9f42006-06-11 16:24:11 +00001845- Bug #1498146: fix optparse to handle Unicode strings in option help,
1846 description, and epilog.
1847
Greg Wardd1c797e2006-06-11 14:42:41 +00001848- Bug #1366250: minor optparse documentation error.

Greg Ward7f547402006-06-11 00:40:49 +00001850- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
1851 clarify docs.
1852
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00001853- The wsgiref package has been added to the standard library.
1854
Nick Coghlan676725d2006-06-08 13:54:49 +00001855- The functions update_wrapper() and wraps() have been added to the functools
1856 module. These make it easier to copy relevant metadata from the original
1857 function when writing wrapper functions.
1858
Tim Petersd6a9eef2006-06-05 01:48:21 +00001859- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
1860 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00001861
Martin v. Löwis3f767792006-06-04 19:36:28 +00001862- Patch #1359618: Speed up charmap encoder by using a trie structure
1863 for lookup.
1864
Tim Petersd609b1a2006-06-02 23:22:51 +00001865- The functions in the ``pprint`` module now sort dictionaries by key
1866 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
1867 if and only if its display required more than one line, although that
1868 wasn't documented. The new behavior increases predictability; e.g.,
1869 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
1870
Georg Brandlfd9a4b12006-05-29 20:57:01 +00001871- Patch #1497027: try HTTP digest auth before basic auth in urllib2

1873
Georg Brandl2b330372006-05-28 20:23:12 +00001874- Patch #1496206: improve urllib2 handling of passwords with respect to
1875 default HTTP and HTTPS ports.
1876
George Yoshidaf3c65de2006-05-28 16:39:09 +00001877- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
1878
Bob Ippolito7298f272006-05-23 18:43:47 +00001879- Patch #1281707: speed up gzip.readline.
1880
Georg Brandlb89316f2006-05-17 15:51:16 +00001881- Patch #1180296: Two new functions were added to the locale module:
1882 format_string() to get the effect of "format % items" but locale-aware,
1883 and currency() to format a monetary number with currency sign.
1884
Georg Brandle3a25832006-05-17 14:56:04 +00001885- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
1886 and several features added, such as speed and geometry control.
1887
Georg Brandl49c8f4c2006-05-15 19:30:35 +00001888- Patch #1488881: add support for external file objects in bz2 compressed
1889 tarfiles.
1890
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001891- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
1892 stdout arguments, making it possible to redirect input and output
1893 for remote debugging.
1894
1895- Patch #1484695: Update the tarfile module to version 0.8. This fixes
1896 a couple of issues, notably handling of long file names using the
1897 GNU LONGNAME extension.
1898
1899- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
1900 new flag when ``name`` is already the name of an option flag.
1901
1902- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
1903 package.
1904
1905- Patch #1472854: make the rlcompleter.Completer class usable on non-
1906 UNIX platforms.
1907

1947-----------------
1948
Thomas Heller1b046642006-04-18 18:51:06 +00001949- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
1950 by converting these apis from macros into exported functions again:
1951
1952 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
1953 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
1954 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
1955 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
1956 PyRun_String Py_CompileString
1957
Martin v. Löwis45294a92006-04-18 06:24:08 +00001958- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
1959
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00001960- All uses of PyStructSequence_InitType have been changed to initialize
1961 the type objects only once, even if the interpreter is initialized
1962 multiple times.
1963
Neal Norwitz61546162006-04-14 05:20:28 +00001964- Bug #1454485, array.array('u') could crash the interpreter. This was
1965 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
1966 to unicode when it didn't make sense. 'u#' now requires a unicode string.
1967
1968- Py_UNICODE is unsigned. It was always documented as unsigned, but
1969 due to a bug had a signed value in previous versions.
1970
Tim Peters3a5e8b12006-04-11 01:44:07 +00001971- Patch #837242: ``id()`` of any Python object always gives a positive
1972 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
1973 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00001974 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00001975 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00001976
Tim Peters3a5e8b12006-04-11 01:44:07 +00001977 def __hash__(self):
1978 return id(self) # WRONG
1979
1980 because a hash result must be a (short) Python int but it was always
1981 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00001982 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00001983 was always usable as a hash value before this patch. That's no longer
1984 necessarily so.
1985
1986- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00001987 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00001988 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00001989 #1454844)
1990
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00001991- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
1992 involving generators that have paused outside of any ``try`` or ``with``
1993 blocks. (In 2.5a1, a paused generator that was part of a reference
1994 cycle could not be garbage collected, regardless of whether it was
1995 paused in a ``try`` or ``with`` block.)

2009 the cachesize parameter.
2010
2011- Bug #1149413: bsddb.*open() no longer raises an exception when using
2012 a temporary db (file=None) with the 'n' flag to truncate on open.

2014- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
2015 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00002016
Armin Rigoa9017c32006-04-19 11:50:27 +00002017- Patch #1062014: AF_UNIX sockets under Linux have a special

Peter Astrand7d1d4362006-07-14 14:04:45 +00002023- Bug #1223937: subprocess.CalledProcessError reports the exit status
2024 of the process using the returncode attribute, instead of
2025 abusing errno.
2026
Tim Peters711bf302006-04-25 03:31:36 +00002027- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2028 a doctest to be skipped (the code is not run, and the expected output
2029 or exception is ignored).
2030
Nick Coghlanda2268f2006-04-24 04:37:15 +00002031- Fixed contextlib.nested to cope with exceptions being raised and
2032 caught inside exit handlers.
2033
Greg Wardab05edc2006-04-23 03:47:58 +00002034- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2035 hex, octal, or binary; add ``append_const`` action; keep going if
2036 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2037 added ``epilog`` for better help generation).
2038
Tim Peters21fbd572006-04-21 21:18:10 +00002039- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2040 called from a thread spawned as a side effect of importing a module.
2041
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002042- The pydoc module now supports documenting packages contained in
2043 .zip or .egg files.
2044
2045- The pkgutil module now has several new utility functions, such
2046 as ``walk_packages()`` to support working with packages that are either
2047 in the filesystem or zip files.
2048
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002049- The mailbox module can now modify and delete messages from
2050 mailboxes, in addition to simply reading them. Thanks to Gregory
2051 K. Johnson for writing the code, and to the 2005 Google Summer of
2052 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002053
Tim Petersc7605f22006-04-17 21:12:33 +00002054- The ``__del__`` method of class ``local`` in module ``_threading_local``
2055 returned before accomplishing any of its intended cleanup.
2056
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002057- Patch #790710: Add breakpoint command lists in pdb.

2076
Skip Montanaro262fb922006-04-21 02:31:07 +00002077- The pstats.Stats class accepts an optional stream keyword argument to
2078 direct output to an alternate file-like object.
2079

2081-----
2082
Martin v. Löwis4be4e652006-04-17 19:25:49 +00002083- The Makefile now has a reindent target, which runs reindent.py on
2084 the library.
2085
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002086- Patch #1470875: Building Python with MS Free Compiler
2087

Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002089
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002090- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2091 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002092 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002093 CXX from --with-cxx-main, see description in README.
2094
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002095- Patch #1429775: Link extension modules with the shared libpython.
2096
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002097- Fixed a libffi build problem on MIPS systems.
2098
Tim Peters8931ff12006-05-13 23:28:20 +00002099- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2100 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2101 and "%zu" for unsigned integers of type ``size_t``.
2102
Anthony Baxter51bcb682006-04-05 14:51:42 +00002103Tests
2104-----
2105
Nick Coghlanda2268f2006-04-24 04:37:15 +00002106- test_contextlib now checks contextlib.nested can cope with exceptions
2107 being raised and caught inside exit handlers.
2108
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002109- test_cmd_line now checks operation of the -m and -c command switches
2110
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002111- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2112 it separately and by hand. It also wasn't cleaning up its changes to
2113 the current Decimal context.
2114
Thomas Woutersabd08882006-04-26 15:53:30 +00002115- regrtest.py now has a -M option to run tests that test the new limits of
2116 containers, on 64-bit architectures. Running these tests is only sensible
2117 on 64-bit machines with more than two gigabytes of memory. The argument
2118 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +00002126Documentation
2127-------------
2128
Tim Petersb06d28c2006-05-12 01:57:59 +00002129- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2130
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002131- PEP 343: Added Context Types section to the library reference
2132 and attempted to bring other PEP 343 related documentation into
2133 line with the implementation and/or python-dev discussions.
2134
Tim Peters8dc73d22006-04-24 02:03:16 +00002135- Bug #1337990: clarified that ``doctest`` does not support examples
2136 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002139What's New in Python 2.5 alpha 1?
2140=================================
2141
Anthony Baxterebed3f62006-04-03 15:03:44 +00002142*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002143
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002144Core and builtins
2145-----------------
2146
Nick Coghlan43832302006-04-23 17:04:07 +00002147- PEP 338: -m command line switch now delegates to runpy.run_module
2148 allowing it to support modules in packages and zipfiles
2149
Martin v. Löwisc661b882006-04-20 04:54:23 +00002150- On Windows, .DLL is not an accepted file name extension for
2151 extension modules anymore; extensions are only found if they
2152 end in .PYD.
2153
Martin v. Löwisea62d252006-04-03 10:56:49 +00002154- Bug #1421664: sys.stderr.encoding is now set to the same value as
2155 sys.stdout.encoding.
2156
Neal Norwitz92e212f2006-04-03 04:48:37 +00002157- __import__ accepts keyword arguments.
2158
Georg Brandlccadf842006-03-31 18:54:53 +00002159- Patch #1460496: round() now accepts keyword arguments.
2160
Anthony Baxter262c00a2006-03-30 10:53:17 +00002161- Fixed bug #1459029 - unicode reprs were double-escaped.
2162
Hye-Shik Changd478f342006-03-23 12:32:36 +00002163- Patch #1396919: The system scope threads are reenabled on FreeBSD
2164 5.4 and later versions.
2165
Neal Norwitze98ccf62006-03-23 05:39:47 +00002166- Bug #1115379: Compiling a Unicode string with an encoding declaration
2167 now gives a SyntaxError.
2168
Georg Brandlabd1ff82006-03-18 07:59:59 +00002169- Previously, Python code had no easy way to access the contents of a
2170 cell object. Now, a ``cell_contents`` attribute has been added
2171 (closes patch #1170323).
2172
Tim Peterscf79aac2006-03-16 01:14:46 +00002173- Patch #1123430: Python's small-object allocator now returns an arena to
2174 the system ``free()`` when all memory within an arena becomes unused
2175 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2176 freed. Some applications will see a drop in virtual memory size now,
2177 especially long-running applications that, from time to time, temporarily
2178 use a large number of small objects. Note that when Python returns an
2179 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002180 platform C library will in turn return that memory to the operating system.
2181 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002182 appears to be effective at least on Microsoft C and gcc-based systems.
2183 Thanks to Evan Jones for hard work and patience.
2184
Georg Brandl533ff6f2006-03-08 18:09:27 +00002185- Patch #1434038: property() now uses the getter's docstring if there is
2186 no "doc" argument given. This makes it possible to legitimately use
2187 property() as a decorator to produce a read-only property.
2188
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002189- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2190 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2191 of requiring an int or long in slicing and a few other contexts, enabling
2192 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2193
Neal Norwitz995acdf2006-03-07 05:01:00 +00002194- Fixed various bugs reported by Coverity's Prevent tool.
2195
Brett Cannonbf364092006-03-01 04:25:17 +00002196- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2197 new exception base class, BaseException, which has a new message attribute.
2198 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2199 Raising a string exception now raises a DeprecationWarning.
2200
Thomas Woutersfb609f42006-02-28 16:37:25 +00002201- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2202 explicitly relative, using 'from .module import name' to mean 'from the same
2203 package as this module is in. Imports without dots still default to the
2204 old relative-then-absolute, unless 'from __future__ import
2205 absolute_import' is used.
2206
Brett Cannona7446e32006-02-27 23:39:10 +00002207- Properly check if 'warnings' raises an exception (usually when a filter set
2208 to "error" is triggered) when raising a warning for raising string
2209 exceptions.
2210
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002211- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002212 The name was removed from Include/code.h.
2213
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002214- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002215
Guido van Rossum1968ad32006-02-25 22:38:04 +00002216- Patch 1433928:
2217 - The copy module now "copies" function objects (as atomic objects).
2218 - dict.__getitem__ now looks for a __missing__ hook before raising
2219 KeyError.
2220
Tim Peters84ef21c2006-02-28 20:39:06 +00002221- PEP 343: with statement implemented. Needs ``from __future__ import
2222 with_statement``. Use of 'with' as a variable will generate a warning.
2223 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002224 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002225 The following objects have __context__ methods:
2226 - The built-in file type.
2227 - The thread.LockType type.
2228 - The following types defined by the threading module:
2229 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2230 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002231
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002232- Fix the encodings package codec search function to only search
2233 inside its own package. Fixes problem reported in patch #1433198.
2234
2235 Note: Codec packages should implement and register their own
2236 codec search function. PEP 100 has the details.
2237
Tim Peters9ea89d22006-06-04 03:26:02 +00002238- PEP 353: Using ``Py_ssize_t`` as the index type.
2239
2240- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2241 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2242 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2243 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2244 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002245
Neal Norwitzfc76d632006-01-10 06:03:13 +00002246- Patch #1400181, fix unicode string formatting to not use the locale.
2247 This is how string objects work. u'%f' could use , instead of .
2248 for the decimal point. Now both strings and unicode always use periods.
2249
Neal Norwitz671b9e32006-01-09 07:07:12 +00002250- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2251 configure would break checking curses.h.
2252
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002253- Bug #959576: The pwd module is now builtin. This allows Python to be
2254 built on UNIX platforms without $HOME set.
2255
Neal Norwitzc10978f2005-12-19 06:07:16 +00002256- Bug #1072182, fix some potential problems if characters are signed.
2257
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002258- Bug #889500, fix line number on SyntaxWarning for global declarations.
2259
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002260- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2261
Neal Norwitze7214a12005-12-18 05:03:17 +00002262- Support for converting hex strings to floats no longer works.
2263 This was not portable. float('0x3') now raises a ValueError.
2264
Barry Warsaw2a38a862005-12-18 01:27:35 +00002265- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002266 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002267 is now displayed in interactive prompt banner.
2268
Georg Brandlfa166682005-12-17 21:45:17 +00002269- Implementation of PEP 341 - Unification of try/except and try/finally.
2270 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002271 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002272
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002273- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2274 now encodes backslash correctly.
2275
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002276- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2277
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002278- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002279 and long longs.
2280
Neal Norwitz67715f02005-11-09 06:59:35 +00002281- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002282 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002283 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002284
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002285- Replaced most Unicode charmap codecs with new ones using the
2286 new Unicode translate string feature in the builtin charmap
2287 codec; the codecs were created from the mapping tables available
2288 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2289 encodings now include a mapping for the Apple logo)
2290
Tim Peterse3547fd2005-12-16 23:13:57 +00002291- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002292
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002293- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002294
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002295- A new AST parser implementation was completed. The abstract
2296 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002297 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002298
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002299- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002300 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2301
Neal Norwitz708e51a2005-10-03 04:48:15 +00002302- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2303
Neal Norwitz11bd1192005-10-03 00:54:56 +00002304- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2305 Provide a warning when a directory is passed on the command line.
2306
Neal Norwitz40d37812005-10-02 01:48:49 +00002307- Fix segfault with invalid coding.
2308
2309- SF bug #772896: unknown encoding results in MemoryError.
2310
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002311- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002312 supported a __len__() method which evaluated to False when the iterator
2313 was empty.
2314
Guido van Rossum630db602005-09-20 18:49:54 +00002315- On 64-bit platforms, when __len__() returns a value that cannot be
2316 represented as a C int, raise OverflowError.
2317
Skip Montanarof8948ca2005-09-19 03:54:46 +00002318- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002319 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002320
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002321- SF bug #893549: parsing keyword arguments was broken with a few format
2322 codes.
2323
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002324- Changes donated by Elemental Security to make it work on AIX 5.3
2325 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2326 bug #105470: test_pwd fails on 64bit system (Opteron).
2327
Guido van Rossum539c6622005-09-14 17:49:54 +00002328- Changes donated by Elemental Security to make it work on HP-UX 11 on
2329 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2330
Georg Brandl4550b8d2005-08-26 06:43:52 +00002331- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002332 (fixes bug #1119418).
2333
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002334- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2335
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002336- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2337 exceptions that cause a function to exit.
2338
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002339- The implementation of set() and frozenset() was revised to use its
2340 own internal data structure. Memory consumption is reduced by 1/3
2341 and there are modest speed-ups as well. The API is unchanged.
2342
Tim Petersde7990b2005-07-17 23:45:23 +00002343- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2344
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002345- SF bug #1229429: PyObject_CallMethod failed to decrement some
2346 reference counts in some error exit cases.
2347
Tim Petersecc6e6a2005-07-10 22:30:55 +00002348- SF bug #1185883: Python's small-object memory allocator took over
2349 a block managed by the platform C library whenever a realloc specified
2350 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002351 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002352 portable way to copy data from the C-managed block into Python's
2353 small-object space without risking a memory fault. Python's small-object
2354 realloc now leaves such blocks under the control of the platform C
2355 realloc.
2356
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002357- SF bug #1232517: An overflow error was not detected properly when
2358 attempting to convert a large float to an int in os.utime().
2359
Raymond Hettinger3296e692005-06-29 23:29:56 +00002360- SF bug #1224347: hex longs now print with lowercase letters just
2361 like their int counterparts.
2362
Michael W. Hudson188d4362005-06-20 16:52:57 +00002363- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2364 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2365 interpreter states; back out that fix and do a better job (see
2366 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2367 for a longer write-up of the problem).
2368
Michael W. Hudsondf888462005-06-03 14:41:55 +00002369- SF patch #1180995: marshal now uses a binary format by default when
2370 serializing floats.
2371
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002372- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2373 the routines that promise to produce IEEE 754 binary representations
2374 of floats now simply copy bytes around.
2375
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002376- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2377 278.
2378
Brett Cannonc3647ac2005-04-26 03:45:26 +00002379- patch #1109424: int, long, float, complex, and unicode now check for the
2380 proper magic slot for type conversions when subclassed. Previously the
2381 magic slot was ignored during conversion. Semantics now match the way
2382 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002383 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002384 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002385 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002386
Barry Warsawc8d907c2005-04-19 23:43:40 +00002387- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2388 NULL, now raise an AttributeError when attempting to set or delete the
2389 attribute. Previously a TypeError was raised, but this was inconsistent
2390 with the equivalent pure-Python implementation.
2391
Michael W. Hudson774479c2005-04-18 08:46:17 +00002392- It is now safe to call PyGILState_Release() before
2393 PyEval_InitThreads() (note that if there is reason to believe there
2394 are multiple threads around you still must call PyEval_InitThreads()
2395 before using the Python API; this fix is for extension modules that
2396 have no way of knowing if Python is multi-threaded yet).
2397
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002398- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2399 disabled caused a crash.
2400
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002401- Bug #1165306: instancemethod_new allowed the creation of a method
2402 with im_class == im_self == NULL, which caused a crash when called.
2403
Tim Petersecc6e6a2005-07-10 22:30:55 +00002404- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002405 fixes the crash seen in bug #1165761
2406
Raymond Hettinger96229b12005-03-11 06:49:40 +00002407- Added two new builtins, any() and all().
2408
Brett Cannon409d8f22005-03-05 06:47:57 +00002409- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002410 (e.g., ``class C(): pass`` is no longer a syntax error).
2411 Patch #1176012 added support to the 'parser' module and 'compiler' package
2412 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002413
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002414- Patch #1115086: Support PY_LONGLONG in structmember.
2415
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002416- Bug #1155938: new style classes did not check that __init__() was
2417 returning None.
2418
Tim Petersecc6e6a2005-07-10 22:30:55 +00002419- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002420 ('\') with a specific error message.
2421
Martin v. Löwisff232d72005-03-03 09:24:38 +00002422- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2423
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002424- Bug #1124295: the __name__ attribute of file objects was
2425 inadvertently made inaccessible in restricted mode.
2426
Tim Petersecc6e6a2005-07-10 22:30:55 +00002427- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002428 an ferror() call.
2429
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002430- min() and max() now support key= arguments with the same meaning as in
2431 list.sort().
2432
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002433- The peephole optimizer now performs simple constant folding in expressions:
2434 (2+3) --> (5).
2435
Raymond Hettingera422c342005-01-11 03:03:27 +00002436- set and frozenset objects can now be marshalled. SF #1098985.
2437
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002438- Bug #1077106: Poor argument checking could cause memory corruption
2439 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002440
Jeremy Hyltonab630502005-02-04 18:44:06 +00002441- The parser did not complain about future statements in illegal
2442 positions. It once again reports a syntax error if a future
2443 statement occurs after anything other than a doc string.
2444
Neil Schemenauercf52c072005-08-12 17:34:58 +00002445- Change the %s format specifier for str objects so that it returns a
2446 unicode instance if the argument is not an instance of basestring and
2447 calling __str__ on the argument returns a unicode instance.
2448
Tim Petersf4e69282006-02-27 17:15:31 +00002449- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2450 current thread state when the auto-GIL-state machinery knows about
2451 it (since the thread state is being deleted, continuing to remember it
2452 can't help, but can hurt if another thread happens to get created with
2453 the same thread id).
2454

2472
2473- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2474
2475- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002476 is deprecated. The undocumented re.engine variable no longer exists.

2480
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002481- The unicodedata module was updated to the 4.1 version of the Unicode
2482 database. The 3.2 version is still available as unicodedata.db_3_2_0
2483 for applications that require this specific version (such as IDNA).
2484
Neal Norwitzb62c4332006-03-04 18:35:47 +00002485- The timing module is no longer built by default. It was deprecated

2506
Martin v. Löwis14694662006-02-03 12:54:16 +00002507- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2508 are reported, the limit on path name lengths is removed, and stat reports
2509 WindowsError now (instead of OSError).
2510

2586 the request code argument, which results in more C-like behaviour
2587 for large or negative values.
2588
Tim Petersecc6e6a2005-07-10 22:30:55 +00002589- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

2628
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002629- the cPickle module no longer accepts the deprecated None option in the
2630 args tuple returned by __reduce__().
2631
Raymond Hettingerb2594052004-12-05 09:25:51 +00002632- itertools.islice() now accepts None for the start and step arguments.
2633 This allows islice() to work more readily with slices:
2634 islice(s.start, s.stop, s.step)
2635
Skip Montanaro0af3ade2005-01-13 04:12:31 +00002636- datetime.datetime() now has a strptime class method which can be used to

Tim Peters112aad32006-07-19 00:03:19 +00002644
Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002645- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2646 been renamed to have only a single underscore prefix. This was done to
2647 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002648
Nick Coghlan43832302006-04-23 17:04:07 +00002649- PEP 338: new module runpy defines a run_module function to support
2650 executing modules which provide access to source code or a code object
2651 via the PEP 302 import mechanisms.
2652
Anthony Baxter93f5b932006-04-03 08:05:07 +00002653- The email module's parsedate_tz function now sets the daylight savings
2654 flag to -1 (unknown) since it can't tell from the date whether it should

2661 in attribute values.
2662
Anthony Baxterc51ee692006-04-01 00:57:31 +00002663- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002664 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002665 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002666 module will not be built.
2667
Tim Petersc17976e2006-04-01 00:26:53 +00002668- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2669 aren't officially supported here, and trying to use them will probably
2670 raise an exception some day. But dicts have been allowed, and "mostly
2671 worked", so support for them won't go away without warning.
2672
Georg Brandl338ef7d2006-03-31 18:42:16 +00002673- Bug #1445068: getpass.getpass() can now be given an explicit stream
2674 argument to specify where to write the prompt.
2675
Georg Brandl22ec80b2006-03-31 18:25:44 +00002676- Patch #1462313, bug #1443328: the pickle modules now can handle classes
2677 that have __private names in their __slots__.
2678

2683
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002684- Queue.Queue objects now support .task_done() and .join() methods
2685 to make it easier to monitor when daemon threads have completed
2686 processing all enqueued tasks. Patch #1455676.
2687
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002688- popen2.Popen objects now preserve the command in a .cmd attribute.
2689
Thomas Hellerc61c0492006-03-22 10:09:27 +00002690- Added the ctypes ffi package.
2691
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002692- email 4.0 package now integrated. This is largely the same as the email 3.0
2693 package that was included in Python 2.3, except that PEP 8 module names are
2694 now used (e.g. mail.message instead of email.Message). The MIME classes
2695 have been moved to a subpackage (e.g. email.mime.text instead of
2696 email.MIMEText). The old names are still supported for now. Several
2697 deprecated Message methods have been removed and lots of bugs have been
2698 fixed. More details can be found in the email package documentation.
2699
Walter Dörwald40108c92006-03-27 08:15:44 +00002700- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2701 (a subclass of tuple) that provides incremental decoders and encoders
2702 (a way to use stateful codecs without the stream API). Python functions
2703 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2704 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2705 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002706
Walter Dörwald067db482006-03-15 22:17:27 +00002707- Patch #1359365: Calling next() on a closed StringIO.String object raises
2708 a ValueError instead of a StopIteration now (like file and cString.String do).
2709 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2710 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002711
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002712- A regrtest option -w was added to re-run failed tests in verbose mode.

2724 and helpful context managers nested() and closing().
2725

2730
Georg Brandlc98eeed2006-02-19 14:57:47 +00002731- Patch #1215184: FileInput now can be given an opening hook which can

Martin v. Löwis3e865952006-01-24 15:51:21 +00002760 specifications, raises IOErrors when proxies for unsupported protocols
2761 are defined, and uses the https proxy on https redirections.

Tim Peterse3547fd2005-12-16 23:13:57 +00002784 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2785 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2786 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2787 Ronald L. Rivest offered this advice for Python:
2788
2789 "The consensus of researchers in this area (at least as
2790 expressed at the NIST Hash Function Workshop 10/31/05),
2791 is that SHA-256 is a good choice for the time being, but
2792 that research should continue, and other alternatives may
2793 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002794
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002795- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandl9e43acf2005-07-04 17:16:07 +00002874- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
2875 as this can cause problems with apps closing all file descriptors.
2876
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002877- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00002878 it can be missing in embedded interpreters
Georg Brandl5284b532005-06-26 22:54:58 +00002879
Georg Brandl2f210b62005-06-26 22:09:06 +00002880- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
2881
Georg Brandlfbff1bc2005-06-26 21:36:25 +00002882- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
2883 error messages.
2884
Georg Brandl379f99d2005-06-26 21:09:38 +00002885- Bug #1108948: Cookie.py produced invalid JavaScript code.
2886
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00002887- The tokenize module now detects and reports indentation errors.
2888 Bug #1224621.
2889
Raymond Hettinger68c04532005-06-10 11:05:19 +00002890- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002891 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00002892 the generate_tokens() function now accepts a callable argument that
2893 terminates by raising StopIteration.
2894
Georg Brandl9166e1a2005-06-04 09:20:03 +00002895- Bug #1196315: fix weakref.WeakValueDictionary constructor.
2896
Georg Brandl268e61c2005-06-03 14:28:50 +00002897- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
2898 component of the path.
2899
Skip Montanaro174dd222005-05-14 20:54:16 +00002900- Patch #1120353: The xmlrpclib module provides better, more transparent,
2901 support for datetime.{datetime,date,time} objects. With use_datetime set
2902 to True, applications shouldn't have to fiddle with the DateTime wrapper
2903 class at all.
2904
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00002905- distutils.commands.upload was added to support uploading distribution
2906 files to PyPI.
2907
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00002908- distutils.commands.register now encodes the data as UTF-8 before posting
2909 them to PyPI.
2910
Raymond Hettinger267b8682005-03-27 10:47:39 +00002911- decimal operator and comparison methods now return NotImplemented
2912 instead of raising a TypeError when interacting with other types. This
2913 allows other classes to implement __radd__ style methods and have them
2914 work as expected.
2915
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00002916- Bug #1163325: Decimal infinities failed to hash. Attempting to
2917 hash a NaN raised an InvalidOperation instead of a TypeError.
2918
Tim Petersecc6e6a2005-07-10 22:30:55 +00002919- Patch #918101: Add tarfile open mode r|* for auto-detection of the

2953
Guido van Rossumd0641422005-02-03 15:01:24 +00002954- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
2955 disables recursive traversal through instance attributes, which can
2956 be exploited in various ways.
2957
Tim Peterse3547fd2005-12-16 23:13:57 +00002958- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00002959 flags on the HTTP listening socket.
2960
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00002961- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
2962 Fixed by reading the HTTP body in chunks instead of one big socket.read().
2963
Fred Drakefbdeaad2006-07-29 16:56:15 +00002964- Patches #893642, #1039083: add allow_none, encoding arguments to
2965 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00002966
Martin v. Löwis1d11de62005-01-29 13:29:23 +00002967- Bug #1110478: Revert os.environ.update to do putenv again.
2968
Thomas Hellerd6c6e222005-01-20 19:20:16 +00002969- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
2970
Martin v. Löwis22b457e2005-01-16 08:40:58 +00002971- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
2972
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002973- Enhancements to the csv module:
2974
2975 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00002976 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00002977 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002978 + Dialect parameter parsing has been re-implemented to improve error
2979 reporting.
2980 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
2981 dictates.
2982 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002983 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00002984 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00002985 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
2986 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00002987 + reader now allows \r characters to be quoted (previously it only allowed
2988 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00002989 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00002990 + Dialect classes passed to the module are no longer instantiated by
2991 the module before being parsed (the former validation scheme required
2992 this, but the mechanism was unreliable).
2993 + The dialect registry now contains instances of the internal
2994 C-coded dialect type, rather than references to python objects.
2995 + the internal c-coded dialect type is now immutable.
2996 + register_dialect now accepts the same keyword dialect specifications
2997 as the reader and writer, allowing the user to register dialects
2998 without first creating a dialect class.
2999 + a configurable limit to the size of parsed fields has been added -
3000 previously, an unmatched quote character could result in the entire
3001 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003002 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003003 the parser field size limit (returning the former limit). The initial
3004 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003005 + A line_num attribute has been added to the reader object, which tracks
3006 the number of lines read from the source iterator. This is not
3007 the same as the number of records returned, as records can span
3008 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003009 + reader and writer objects were not being registered with the cyclic-GC.
3010 This has been fixed.
3011
Brett Cannone6539c42005-01-08 02:43:53 +00003012- _DummyThread objects in the threading module now delete self.__block that is
3013 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3014 lock primitives tend to be limited in number and thus should not be wasted on
3015 a _DummyThread object. Fixes bug #1089632.
3016
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003017- The imghdr module now detects Exif files.
3018
Raymond Hettinger6065d322004-12-20 23:51:53 +00003019- StringIO.truncate() now correctly adjusts the size attribute.
3020 (Bug #951915).
3021
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003022- locale.py now uses an updated locale alias table (built using
3023 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3024 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003025 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003026
Raymond Hettinger3557f422004-12-07 12:02:02 +00003027- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3028
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003029- the pickle module no longer accepts the deprecated None option in the
3030 args tuple returned by __reduce__().
3031
Brett Cannon84667c02004-12-07 03:25:18 +00003032- optparse now optionally imports gettext. This allows its use in setup.py.
3033
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003034- the pickle module no longer uses the deprecated bin parameter.
3035
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003036- the shelve module no longer uses the deprecated binary parameter.
3037
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003038- the pstats module no longer uses the deprecated ignore() method.
3039
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003040- the filecmp module no longer uses the deprecated use_statcache argument.
3041
Raymond Hettinger664347b2004-12-04 21:21:53 +00003042- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3043 extended or overridden by subclasses. Formerly, the subclassed method would
3044 be ignored by the rest of the module. (Bug #1078905).
3045
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003046- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003047 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003048
Walter Dörwald36733692004-12-22 12:50:50 +00003049- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3050 once when a size argument is given. This prevents a buffer overflow in the
3051 tokenizer with very long source lines.
3052
Barry Warsaw538561e2006-01-01 21:48:54 +00003053- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3054 immediately after creating the object, without any intervening
3055 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003056
Skip Montanaro05885812005-01-16 20:48:27 +00003057- The reconvert.quote function can now emit triple-quoted strings. The
3058 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003059
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003060- ``UserString.MutableString`` now supports negative indices in
3061 ``__setitem__`` and ``__delitem__``
3062
Greg Ward40407942005-03-05 02:53:17 +00003063- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3064 correctly.
3065
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003066- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3067 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3068 character even if the user has passed a size parameter to get a proper
3069 line ending. Remove the special handling of a "\r\n" that has been split
3070 between two lines.
3071
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003072- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3073 about illegal code points. The codec now supports PEP 293 style error
3074 handlers.
3075
Walter Dörwald78a78b02005-09-01 12:04:29 +00003076- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003077 from the input stream, so that the output is a byte string in the correct
3078 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003079
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003080- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3081 considering it exactly like a '*'.
3082
Walter Dörwald007f8df2005-10-09 19:42:27 +00003083- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3084 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003085
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003086- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3087
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003088- Patch #1413711: Certain patterns of differences were making difflib
3089 touch the recursion limit.
3090
Walter Dörwald58917a62006-03-31 15:26:22 +00003091- Bug #947906: An object oriented interface has been added to the calendar
3092 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003093 called as a script (e.g. via ``python -mcalendar``). Localized month and
3094 weekday names can be ouput (even if an exotic encoding is used) using
3095 special classes that use unicode.

Brett Cannon08cd5982005-04-24 22:26:38 +00003122- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3123 flags that change binary compatibility. Changes were also made to
3124 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003125 compilation of the interpreter and of C extensions through distutils.

Brett Cannon46d96232005-02-16 00:07:19 +00003133- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3134 defined. Discovered as a result of not being able to build on OS X.
3135
Brett Cannon516592f2004-12-07 00:42:59 +00003136- setup.py now uses the directories specified in LDFLAGS using the -L option
3137 and in CPPFLAGS using the -I option for adding library and include
3138 directories, respectively, for compiling extension modules against. This has
3139 led to the core being compiled using the values in CPPFLAGS. It also removes
3140 the need for the special-casing of both DarwinPorts and Fink for darwin since
3141 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3142 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3143 Fink, ``-I/opt/local/include`` for DarwinPorts).
3144
Brett Cannon43802422005-02-10 20:48:03 +00003145- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3146 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3147 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3148 Closes bug #1096244. Thanks Gregory Bond.

3151-----
3152
Tim Petersc9d78aa2006-03-26 23:27:58 +00003153- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3154 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3155 is obtained via the ``PyObject_`` family, it must be released via the
3156 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3157 always been officially true, but when Python's small-object allocator was
3158 introduced, an attempt was made to cater to a few extension modules
3159 discovered at the time that obtained memory via ``PyObject_New`` but
3160 released it via ``PyMem_DEL``. It's years later, and if such code still
3161 exists it will fail now (probably with segfaults, but calling wrong
3162 low-level memory management functions can yield many symptoms).
3163
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003164- Added a C API for set and frozenset objects.
3165
Raymond Hettinger66517482004-12-03 11:45:13 +00003166- Removed PyRange_New().
3167
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003168- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3169 mapping argument now. This string is used as a mapping table. Byte values
3170 greater than the length of the string and 0xFFFE are treated as undefined
3171 mappings.

Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00003179- Patch #1276356: New resource "urlfetch" is implemented. This enables
3180 even impatient people to run tests that require remote files.
