57 method does not return iterators for the 4th and 5th items.
58
Amaury Forgeot d'Arcb50f9922008-09-26 22:46:01 +000059- Issue #3967: Fixed a crash in the count() and find() methods of string-like
60 objects, when the "start" parameter is a huge value.

74 was not always being done properly in some python types and extension
75 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
76 all been updated to perform better checks and places in the code that
77 would previously leak memory on the error path when such an allocation
78 failed have been fixed.

88 another file in sys.stdout.
89
Amaury Forgeot d'Arcb15bdf72008-07-01 20:59:49 +000090- Issue #3088: Corrected a race condition in classes derived from

95 holds the last (strong) reference to its referent.
96
Guido van Rossumaa975432008-04-10 22:43:58 +000097- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
98 having a self-referential tuple, which is possible from C code. Nor did
99 object's tp_str consider that a type's tp_str could do something that could
100 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
101 respectively, fixed the issues. (Backport of r58288 from trunk.)
102

107 reference on the outer class name.
108
Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +0000109- Issue #1477: With narrow Unicode builds, the unicode escape sequence
110 \Uxxxxxxxx did not accept values outside the Basic Multilingual Plane. This
111 affected raw unicode literals and the 'raw-unicode-escape' codec. Now
112 UTF-16 surrogates are generated in this case, like normal unicode literals
113 and the 'unicode-escape' codec.
114
Neal Norwitzb3635f92008-03-18 04:17:36 +0000115- Issue #2321: use pymalloc for unicode object string data to reduce
116 memory usage in some circumstances.
Andrew M. Kuchlingbe0adfc2008-02-23 17:18:19 +0000117
Sean Reifscheider4af861c2008-03-20 17:39:31 +0000118- Issue #2238: Some syntax errors in *args and **kwargs expressions could give

122 parameter but was not verifying that it was greater than zero. Values
123 less than zero will now raise a SystemError and return NULL to indicate a
124 bug in the calling C code.
125
Gregory P. Smith9aa040d2008-06-02 00:07:25 +0000126- Issue #2588, #2589: Fix potential integer underflow and overflow
127 conditions in the PyOS_vsnprintf C API function.
128
Gregory P. Smithcae7f882008-09-07 06:44:12 +0000129- Issue #1204: The configure script now tests for additional libraries
130 that may be required when linking against readline. This fixes issues
131 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
Georg Brandld9f1da02008-03-29 01:50:46 +0000132
Gregory P. Smitha7a94a02008-09-22 00:22:44 +0000133- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
134 library targets in the Makefile.

Amaury Forgeot d'Arc22679b82008-08-18 19:33:42 +0000172- Issue #2234: distutils failed for some versions of the cygwin compiler. The
173 version reported by these tools does not necessarily follow the python
174 version numbering scheme, so the module is less strict when parsing it.
175
Hirokazu Yamamoto1d63a452008-08-17 09:49:10 +0000176- Issue #2222: Fixed reference leak when occured os.rename()

1160-----------------
1161
Neal Norwitz0bcafac2006-09-11 08:51:17 +00001162- Make _PyGILState_NoteThreadState() static, it was not used anywhere
1163 outside of pystate.c and should not be necessary.
1164
Brett Cannon19d76c52006-09-09 07:18:44 +00001165- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
1166 allows calling unicode() on exceptions classes directly to succeed.
1167
Georg Brandlecab6232006-09-06 06:47:02 +00001168- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
1169 Also make sure that every exception class has __module__ set to
1170 'exceptions'.
1171
Georg Brandl37a9e572006-09-06 06:09:34 +00001172- Bug #1550983: emit better error messages for erroneous relative
1173 imports (if not in package and if beyond toplevel package).
1174
Tim Peterscbdd3502006-09-05 01:47:53 +00001175- Overflow checking code in integer division ran afoul of new gcc
1176 optimizations. Changed to be more standard-conforming.

1182
Neal Norwitz29a5fdb2006-09-05 02:21:38 +00001183- The return tuple from str.rpartition(sep) is (tail, sep, head) where
1184 head is the original string if sep was not found.
1185
Neal Norwitz3b3aae02006-09-05 03:56:01 +00001186- Bug #1520864: unpacking singleton tuples in list comprehensions and
1187 generator expressions (x for x, in ... ) works again. Fixing this problem
1188 required changing the .pyc magic number. This means that .pyc files
1189 generated before 2.5c2 will be regenerated.

1301Core and builtins
1302-----------------
1303
Neal Norwitz24b6f202006-09-05 04:43:56 +00001304- Fix infinite recursion when subclassing long and overriding __hash__.
1305
1306- Fix concatenation (+=) of long strings.
1307
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001308- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001309 compared equal or unequal to a string and a UnicodeDecodeError
1310 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001311
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001312 Instead, the equal (==) and unequal (!=) comparison operators will
1313 now issue a UnicodeWarning and interpret the two objects as
1314 unequal. The UnicodeWarning can be filtered as desired using
1315 the warning framework, e.g. silenced completely, turned into an
1316 exception, logged, etc.
1317
1318 Note that compare operators other than equal and unequal will still
1319 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001320
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001321- Fix segfault when doing string formatting on subclasses of long.
1322
1323- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1324 with new-style classes.
1325
1326- Fix bug related to __len__ functions returning negative values with
1327 classic classes.
1328
1329- Patch #1538606, Fix __index__() clipping. There were some problems
1330 discovered with the API and how integers that didn't fit into Py_ssize_t
1331 were handled. This patch attempts to provide enough alternatives
1332 to effectively use __index__.
1333
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001334- Bug #1536021: __hash__ may now return long int; the final hash
1335 value is obtained by invoking hash on the long int.
1336
Thomas Hellerab1049c2006-08-08 17:37:00 +00001337- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1338
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001339- Bug #1535165: fixed a segfault in input() and raw_input() when
1340 sys.stdin is closed.
1341
Thomas Heller74d36f02006-08-04 18:17:40 +00001342- On Windows, the PyErr_Warn function is now exported from
1343 the Python dll again.
1344
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001345- Bug #1191458: tracing over for loops now produces a line event
1346 on each iteration. Fixing this problem required changing the .pyc
1347 magic number. This means that .pyc files generated before 2.5c1
1348 will be regenerated.
1349
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001350- Bug #1333982: string/number constants were inappropriately stored
1351 in the byte code and co_consts even if they were not used, ie
1352 immediately popped off the stack.
1353
Georg Brandle9462c72006-08-04 18:03:37 +00001354- Fixed a reference-counting problem in property().

1357Library
1358-------
1359
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001360- Fix a bug in the ``compiler`` package that caused invalid code to be
1361 generated for generator expressions.
1362
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001363- The distutils version has been changed to 2.5.0. The change to
1364 keep it programmatically in sync with the Python version running
1365 the code (introduced in 2.5b3) has been reverted. It will continue
1366 to be maintained manually as static string literal.
1367
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001368- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001369 and this cannot be converted to the required C type, an exception is
1370 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001371 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001372
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001373- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001374 an exception.
1375
Tim Peterscbdd3502006-09-05 01:47:53 +00001376- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001377 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001378 workarounds for clocks with low resolution, to stop the code yielding
1379 duplicate UUIDs.
1380
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001381- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1382 before raising SystemExit, allowing IDLE to honor quit() and exit().
1383
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001384- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1385
Georg Brandl7a1af772006-08-14 21:55:28 +00001386- Patch #1536071: trace.py should now find the full module name of a
1387 file correctly even on Windows.
1388
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001389- logging's atexit hook now runs even if the rest of the module has
1390 already been cleaned up.
1391
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001392- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001393
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001394- Bug #1531405, format_exception no longer raises an exception if
1395 str(exception) raised an exception.
1396
Neil Schemenauer06ded092006-08-04 16:20:30 +00001397- Fix a bug in the ``compiler`` package that caused invalid code to be
1398 generated for nested functions.

Thomas Heller86720042006-08-14 11:17:48 +00001414- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1415 uses the _as_parameter_ attribute when objects are passed to foreign
1416 function calls. The ctypes version number was changed to 1.0.1.
1417
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001418- Bug #1530559, struct.pack raises TypeError where it used to convert.
1419 Passing float arguments to struct.pack when integers are expected
1420 now triggers a DeprecationWarning.

Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001457- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1458
Tim Peters4643c2f2006-08-10 22:45:34 +00001459- Bug #1069160. Internal correctness changes were made to
1460 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1461 the documentation was changed to state that the return value
1462 is always 1 (normal) or 0 (if the specified thread wasn't found).

1470Core and builtins
1471-----------------
1472
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001473- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001474 returned a long (see PEP 353).
1475
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001476- Bug #1515471: string.replace() accepts character buffers again.
1477
Neal Norwitz07aadb12006-07-30 06:55:48 +00001478- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1479 This provides the proper warning for struct.pack().
1480 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1481
Neal Norwitz0d62a062006-07-30 06:53:31 +00001482- Patch #1531113: Fix augmented assignment with yield expressions.
1483 Also fix a SystemError when trying to assign to yield expressions.
1484
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001485- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1486 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1487 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1488 excessive filesystem operations during imports.
1489
Tim Petersbc24eee2006-07-27 01:14:53 +00001490- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1491 operations on signed longs that are formally undefined by C.
1492 Unfortunately, at least one compiler now cares about that, so complicated
1493 the code to make that compiler happy again.
1494
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001495- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1496
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001497- Patch #1232023: Stop including current directory in search
1498 path on Windows.
1499
Neal Norwitze1fdb322006-07-21 05:32:28 +00001500- Fix some potential crashes found with failmalloc.
1501
Neal Norwitze7563102006-07-17 01:00:16 +00001502- Fix warnings reported by Klocwork's static analysis tool.
1503
Neal Norwitz84be93b2006-07-16 01:50:38 +00001504- Bug #1512814, Fix incorrect lineno's when code within a function
1505 had more than 255 blank lines.
1506
Georg Brandl9dceedb2006-07-12 15:31:17 +00001507- Patch #1521179: Python now accepts the standard options ``--help`` and
1508 ``--version`` as well as ``/?`` on Windows.
1509
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001510- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001511 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001512 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001513
Tim Peters112aad32006-07-19 00:03:19 +00001514- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001515 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001516 new ``sys._current_frames()`` returns a dictionary with one entry,
1517 mapping the faux "thread id" 0 to the current frame.
1518
Ronald Oussoren3075e162006-07-25 20:28:55 +00001519- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001520

1523-------
1524
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001525- Correction of patch #1455898: In the mbcs decoder, set final=False
1526 for stream decoder, but final=True for the decode function.
1527
Georg Brandl07fec3a2006-08-01 18:49:24 +00001528- os.urandom no longer masks unrelated exceptions like SystemExit or
1529 KeyboardInterrupt.
1530
Tim Peters4643c2f2006-08-10 22:45:34 +00001531- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001532 shutil.copytree on Windows
1533
Georg Brandle34ac7c2006-07-30 11:07:23 +00001534- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1535 refers to file descriptors, not file objects.
1536
Tim Peterscbdd3502006-09-05 01:47:53 +00001537- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001538 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001539 #1513611, and probably others.
1540
Georg Brandledd9b0d2006-07-29 09:33:26 +00001541- Bug #1441397: The compiler module now recognizes module and function
1542 docstrings correctly as it did in Python 2.4.
1543
Tim Peters6f681472006-07-27 23:44:37 +00001544- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1545 lost that tests are sorted by name before being run. This rarely
1546 matters for well-written tests, but can create baffling symptoms if
1547 side effects from one test to the next affect outcomes. ``DocTestFinder``
1548 has been changed to sort the list of tests it returns.
1549
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001550- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001551 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001552
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001553- Bug #978833: Really close underlying socket in _socketobject.close.
1554
Georg Brandldb232dc2006-08-20 13:15:43 +00001555- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1556 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001557
Georg Brandlcf0c1722006-07-26 07:23:32 +00001558- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1559 to recursive calls and call it with the failing package name.
1560
Martin v. Löwis0b483032006-07-25 09:53:12 +00001561- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1562
Georg Brandlc13c34c2006-07-24 14:09:56 +00001563- Patch #1515343: Fix printing of deprecated string exceptions with a
1564 value in the traceback module.
1565
Greg Ward48fae7a2006-07-23 16:05:51 +00001566- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1567
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001568- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1569
Brett Cannoncaebe222006-07-18 04:41:36 +00001570- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1571 argument tuple. For arguments where zero is illegal, the value is forced to
1572 the minimum value that is correct. This is to support an undocumented but
1573 common way people used to fill in inconsequential information in the time
1574 tuple pre-2.4.
1575
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001576- Patch #1220874: Update the binhex module for Mach-O.
1577
Barry Warsawb110bad2006-07-21 14:51:07 +00001578- The email package has improved RFC 2231 support, specifically for
1579 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1580 (name*0=<blah>) parameter continuations. This may change the types of
1581 values returned from email.message.Message.get_param() and friends.
1582 Specifically in some cases where non-encoded continuations were used,
1583 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1584 will just return the string (since non-encoded continuations don't have
1585 charset and language parts).
1586
1587 Also, whereas % values were decoded in all parameter continuations, they are
1588 now only decoded in encoded parameter parts.
1589
Ronald Oussoren3075e162006-07-25 20:28:55 +00001590- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1591
1592- Bug #1517996: IDLE now longer shows the default Tk menu when a
1593 path browser, class browser or debugger is the frontmost window on MacOS X
1594
Barry Warsaw00decd72006-07-27 23:43:15 +00001595- Patch #1520294: Support for getset and member descriptors in types.py,
1596 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1597 of an object against these built-in types and more importantly, for getting
1598 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001601Extension Modules
1602-----------------
1603
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001604- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1605 a socket operation on a socket with a timeout, the exception will be
1606 caught correctly. Previously, the exception was not caught.
1607
Thomas Heller1393d6a2006-07-28 21:43:20 +00001608- Patch #1529514: The _ctypes extension is now compiled on more
1609 openbsd target platforms.
1610
Tim Peters9cab5932006-07-28 00:30:00 +00001611- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1612 a memory leak, affecting pickles and deep copies.
1613
Tim Petersbc24eee2006-07-27 01:14:53 +00001614- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001615 Paul Eggert.
1616
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001617- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1618
Thomas Hellerce049a02006-07-14 17:51:14 +00001619- Patch #1521817: Index range checking on ctypes arrays containing
1620 exactly one element enabled again. This allows iterating over these
1621 arrays, without the need to check the array size before.
1622
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001623- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001624 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001625 /dev/null in certain cases; this is now fixed.
1626
Thomas Heller47d7a062006-07-12 08:43:47 +00001627- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1628 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001629
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001630- Because of a misspelled preprocessor symbol, ctypes was always
1631 compiled without thread support; this is now fixed.
1632
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001633- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1634 methods now allow their database parameter to be None as the
1635 sleepycat API allows.
1636
Matt Flemingec926502006-07-28 11:27:27 +00001637- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1638 bluetooth API compared with Linux and FreeBSD.
1639
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001640Tests
1641-----
1642
1643- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1644 how long the test file should take to play. Now accepts taking 2.93 secs
1645 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1646
Georg Brandl4793aa32006-07-28 18:31:39 +00001647- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1648 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1649 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001656Mac
1657---
1658
1659- PythonLauncher now works correctly when the path to the script contains
1660 characters that are treated specially by the shell (such as quotes).
1661
1662- Bug #1527397: PythonLauncher now launches scripts with the working directory
1663 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001664 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001665 expect.

1675
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001676- Bug #1441486: The literal representation of -(sys.maxint - 1)
1677 again evaluates to a int object, not a long.
1678
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001679- Bug #1501934: The scope of global variables that are locally assigned
1680 using augmented assignment is now correctly determined.
1681
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001682- Bug #927248: Recursive method-wrapper objects can now safely
1683 be released.
1684
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001685- Bug #1417699: Reject locale-specific decimal point in float()
1686 and atof().
1687
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001688- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1689 omit a default "error" argument for NULL pointer. This allows
1690 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001691
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001692- Bug #1519018: 'as' is now validated properly in import statements.
1693
Neal Norwitz28746ab2006-07-09 22:14:42 +00001694- On 64 bit systems, int literals that use less than 64 bits are
1695 now ints rather than longs.
1696
Neal Norwitzed657552006-07-10 00:04:44 +00001697- Bug #1512814, Fix incorrect lineno's when code at module scope
1698 started after line 256.
1699
Tim Peters32a83612006-07-10 21:08:24 +00001700- New function ``sys._current_frames()`` returns a dict mapping thread
1701 id to topmost thread stack frame. This is for expert use, and is
1702 especially useful for debugging application deadlocks. The functionality
1703 was previously available in Fazal Majid's ``threadframe`` extension
1704 module, but it wasn't possible to do this in a wholly threadsafe way from
1705 an extension.

Martin v. Löwis77621582006-07-30 13:27:31 +00001710- Bug #1257728: Mention Cygwin in distutils error message about a missing
1711 VS 2003.
1712
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001713- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1714
Tim Peters32a83612006-07-10 21:08:24 +00001715- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001716 environment variable to be set in order to the SDK environment
1717 for finding the compiler, include files, etc.

Nick Coghlan2d792252006-07-06 13:47:18 +00001721- warnings.py now ignores ImportWarning by default
1722
Thomas Woutersadd19112006-07-05 11:03:49 +00001723- string.Template() now correctly handles tuple-values. Previously,
1724 multi-value tuples would raise an exception and single-value tuples would
1725 be treated as the value they contain, instead.
1726
Martin v. Löwisede77f52006-07-03 13:01:35 +00001727- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1728 even if some data are received.

Martin v. Löwis2b88f632006-07-03 10:19:49 +00001737 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001738
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001739- Bug #1514703: Only setup canvas window in turtle when the canvas
1740 is created.
1741
Martin v. Löwis7596e832006-07-01 15:33:37 +00001742- Bug #1513223: .close() of a _socketobj now releases the underlying
1743 socket again, which then gets closed as it becomes unreferenced.
1744
Fred Drake10497c82006-06-29 02:57:48 +00001745- Bug #1504333: Make sgmllib support angle brackets in quoted
1746 attribute values.
1747
1748- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1749 sgmllib ('[' and ']' were not accepted).
1750

1752
Brett Cannon53ab5b72006-06-22 16:49:14 +00001753- Bug #1510580: The 'warnings' module improperly required that a Warning
1754 category be either a types.ClassType and a subclass of Warning. The proper
1755 check is just that it is a subclass with Warning as the documentation states.
1756
Georg Brandlad29e632006-06-21 17:45:17 +00001757- The compiler module now correctly compiles the new try-except-finally
1758 statement (bug #1509132).
1759
Neal Norwitz60373cd2006-06-22 06:30:50 +00001760- The wsgiref package is now installed properly on Unix.
1761

1763 shutdown when fileConfig() was called multiple times.
1764
Gerhard Häring762fbd32006-07-02 17:48:30 +00001765- The sqlite3 module did cut off data from the SQLite database at the first
1766 null character before sending it to a custom converter. This has been fixed
1767 now.
1768
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001769Extension Modules
1770-----------------
1771
Tim Peters112aad32006-07-19 00:03:19 +00001772- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1773 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1774 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001775
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001776- Assigning None to pointer type fields in ctypes structures possible
1777 overwrote the wrong fields, this is fixed now.
1778
1779- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1780 on non-Windows platforms.
1781
1782- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1783 integer or long, without range checking.
1784
1785- Patch #1517790: It is now possible to use custom objects in the ctypes
1786 foreign function argtypes sequence as long as they provide a from_param
1787 method, no longer is it required that the object is a ctypes type.
1788
1789- The '_ctypes' extension module now works when Python is configured
1790 with the --without-threads option.
1791
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001792- Bug #1513646: os.access on Windows now correctly determines write
1793 access, again.
1794
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001795- Bug #1512695: cPickle.loads could crash if it was interrupted with

1807
Tim Peters32a83612006-07-10 21:08:24 +00001808- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001809 Previously, the slight difference could cause compilation errors of the
1810 'zlib' module on systems with more than one version of zlib.
1811
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001812- The MSI compileall step was fixed to also support a TARGETDIR

Anthony Baxter51bcb682006-04-05 14:51:42 +00001842
1843Core and builtins
1844-----------------
1845
Georg Brandla56b9152006-06-19 06:35:54 +00001846- Patch #1507676: Error messages returned by invalid abstract object operations
1847 (such as iterating over an integer) have been improved and now include the
1848 type of the offending object to help with debugging.
1849
Brett Cannonea3912b2006-06-13 21:46:41 +00001850- Bug #992017: A classic class that defined a __coerce__() method that returned
1851 its arguments swapped would infinitely recurse and segfault the interpreter.
1852
Neal Norwitz909eb122006-06-12 02:13:21 +00001853- Fix the socket tests so they can be run concurrently.
1854
Neal Norwitzb9845e72006-06-12 02:11:18 +00001855- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001856 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001857
Brett Cannon22565aa2006-06-09 22:31:23 +00001858- Bug #532646: object.__call__() will continue looking for the __call__
1859 attribute on objects until one without one is found. This leads to recursion
1860 when you take a class and set its __call__ attribute to an instance of the
1861 class. Originally fixed for classic classes, but this fix is for new-style.
1862 Removes the infinite_rec_3 crasher.
1863
Georg Brandl24250812006-06-09 18:45:48 +00001864- The string and unicode methods startswith() and endswith() now accept
1865 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1866
Brett Cannonde3b0522006-06-08 17:00:45 +00001867- Buffer objects, at the C level, never used the char buffer
1868 implementation even when the char buffer for the wrapped object was
1869 explicitly requested (originally returned the read or write buffer).
1870 Now a TypeError is raised if the char buffer is not present but is
1871 requested.
1872
Georg Brandlddbaa662006-06-04 21:56:52 +00001873- Patch #1346214: Statements like "if 0: suite" are now again optimized
1874 away like they were in Python 2.4.
1875
Georg Brandlb7c8f542006-05-27 12:30:25 +00001876- Builtin exceptions are now full-blown new-style classes instead of
1877 instances pretending to be classes, which speeds up exception handling
1878 by about 80% in comparison to 2.5a2.
1879
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001880- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1881 Unicode 4.1.
1882
Georg Brandlf4ef1162006-05-26 18:03:31 +00001883- Patch #921466: sys.path_importer_cache is now used to cache valid and
1884 invalid file paths for the built-in import machinery which leads to
1885 fewer open calls on startup.
1886
Tim Peters696cf432006-05-24 21:10:40 +00001887- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1888 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1889 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1890 the number of input digits (it was and remains linear-time for bases
1891 2, 4, 8, 16 and 32).
1892
Tim Petersb713ec22006-05-23 18:45:30 +00001893- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1894 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1895 an integer close to ``sys.maxint``. This was repaired by patch
1896 #1335972, which also gives a nice speedup.
1897
Richard Jonescebbefc2006-05-23 18:28:17 +00001898- Patch #1337051: reduced size of frame objects.
1899
1900- PyErr_NewException now accepts a tuple of base classes as its
1901 "base" parameter.
1902
Richard Jones7c88dcc2006-05-23 10:37:38 +00001903- Patch #876206: function call speedup by retaining allocated frame
1904 objects.
1905
Georg Brandl7b90e162006-05-18 07:01:27 +00001906- Bug #1462152: file() now checks more thoroughly for invalid mode
1907 strings and removes a possible "U" before passing the mode to the
1908 C library function.
1909
Neal Norwitz1004a532006-05-15 07:17:23 +00001910- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1911
Neal Norwitz373f0a72006-05-15 07:04:36 +00001912- Bug #1487966: Fix SystemError with conditional expression in assignment
1913
Martin v. Löwis879768d2006-05-11 13:28:43 +00001914- WindowsError now has two error code attributes: errno, which carries
1915 the error values from errno.h, and winerror, which carries the error
1916 values from winerror.h. Previous versions put the winerror.h values
1917 (from GetLastError()) into the errno attribute.
1918
Martin v. Löwis77736712006-05-04 05:51:03 +00001919- Patch #1475845: Raise IndentationError for unexpected indent.
1920
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001921- Patch #1479181: split open() and file() from being aliases for each other.
1922
Tim Peters44bd9862006-06-01 13:49:23 +00001923- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1924 methods were always silently ignored by dictionaries when comparing keys.
1925 They are now passed through (except when using the C API function
1926 ``PyDict_GetItem()``, whose semantics did not change).
1927
1928- Bug #1456209: In some obscure cases it was possible for a class with a
1929 custom ``__eq__()`` method to confuse dict internals when class instances
1930 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1931 No, you don't have any code that did this ;-)

1944
Nick Coghlanc649ec52006-05-29 12:43:05 +00001945- Patch #1478788 (modified version): The functional extension module has
1946 been renamed to _functools and a functools Python wrapper module added.
1947 This provides a home for additional function related utilities that are
1948 not specifically about functional programming. See PEP 309.
1949
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001950- Patch #1493701: performance enhancements for struct module.

1958 enabled builds on Windows and systems with Posix threads support.
1959
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001960- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1961 (up to the system limit of 32K characters).
1962
1963- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1964 As a result, these functions now raise WindowsError instead of OSError.
1965
Tim Peters7a822da2006-05-25 21:50:17 +00001966- ``time.clock()`` on Win64 should use the high-performance Windows
1967 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1968 Windows platforms).
1969
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001970- Calling Tk_Init twice is refused if the first call failed as that
1971 may deadlock.
1972
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001973- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1974 accept it without potentially using an uninitialized pointer.
1975
1976- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1977 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

1987 results. It could previously incorrectly return 0 in some cases.
1988 Fixes SF bug 1493322 (pybsddb bug 1184012).
1989
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001990- bsddb: the bsddb.dbtables Modify method now raises the proper error and

1992 Fixes SF python patch/bug #1408584.
1993
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001994- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001995 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001996 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1997 database calls that would previously deadlock. [SF python bug #775414]

Georg Brandl83cc0d02006-06-14 08:50:03 +00002020- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
2021 mime.types file for determining MIME types.
2022
Georg Brandl2605ca82006-06-14 06:08:31 +00002023- Bug #1339007: Shelf objects now don't raise an exception in their
2024 __del__ method when initialization failed.
2025
Martin v. Löwisd8251432006-06-14 05:21:04 +00002026- Patch #1455898: The MBCS codec now supports the incremental mode for
2027 double-byte encodings.
2028
Tim Peters43898b42006-06-14 04:09:25 +00002029- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
2030 guarantee that adjacent triples in the return list always describe
2031 non-adjacent blocks. Previously, a pair of matching blocks could end
2032 up being described by multiple adjacent triples that formed a partition
2033 of the matching pair.
2034
Greg Ward0e0c9f42006-06-11 16:24:11 +00002035- Bug #1498146: fix optparse to handle Unicode strings in option help,
2036 description, and epilog.
2037
Greg Wardd1c797e2006-06-11 14:42:41 +00002038- Bug #1366250: minor optparse documentation error.
2039
Greg Ward7f547402006-06-11 00:40:49 +00002040- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
2041 clarify docs.
2042
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00002043- The wsgiref package has been added to the standard library.
2044
Nick Coghlan676725d2006-06-08 13:54:49 +00002045- The functions update_wrapper() and wraps() have been added to the functools
2046 module. These make it easier to copy relevant metadata from the original
2047 function when writing wrapper functions.
2048
Tim Petersd6a9eef2006-06-05 01:48:21 +00002049- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
2050 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00002051
Martin v. Löwis3f767792006-06-04 19:36:28 +00002052- Patch #1359618: Speed up charmap encoder by using a trie structure
2053 for lookup.
2054
Tim Petersd609b1a2006-06-02 23:22:51 +00002055- The functions in the ``pprint`` module now sort dictionaries by key
2056 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
2057 if and only if its display required more than one line, although that
2058 wasn't documented. The new behavior increases predictability; e.g.,
2059 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
2060
Georg Brandlfd9a4b12006-05-29 20:57:01 +00002061- Patch #1497027: try HTTP digest auth before basic auth in urllib2
2062 (thanks for J. J. Lee).
2063
Georg Brandl2b330372006-05-28 20:23:12 +00002064- Patch #1496206: improve urllib2 handling of passwords with respect to
2065 default HTTP and HTTPS ports.
2066
George Yoshidaf3c65de2006-05-28 16:39:09 +00002067- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
2068
Bob Ippolito7298f272006-05-23 18:43:47 +00002069- Patch #1281707: speed up gzip.readline.
2070
Georg Brandlb89316f2006-05-17 15:51:16 +00002071- Patch #1180296: Two new functions were added to the locale module:
2072 format_string() to get the effect of "format % items" but locale-aware,
2073 and currency() to format a monetary number with currency sign.
2074
Georg Brandle3a25832006-05-17 14:56:04 +00002075- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
2076 and several features added, such as speed and geometry control.
2077
Georg Brandl49c8f4c2006-05-15 19:30:35 +00002078- Patch #1488881: add support for external file objects in bz2 compressed
2079 tarfiles.
2080
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002081- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
2082 stdout arguments, making it possible to redirect input and output
2083 for remote debugging.
2084
2085- Patch #1484695: Update the tarfile module to version 0.8. This fixes
2086 a couple of issues, notably handling of long file names using the
2087 GNU LONGNAME extension.
2088
2089- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
2090 new flag when ``name`` is already the name of an option flag.
2091
2092- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
2093 package.
2094
2095- Patch #1472854: make the rlcompleter.Completer class usable on non-
2096 UNIX platforms.
2097
2098- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
2099
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00002100- Bug #1472827: correctly escape newlines and tabs in attribute values in
2101 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00002131What's New in Python 2.5 alpha 2?
2132=================================
2133
2134*Release date: 27-APR-2006*
2135
2136Core and builtins
2137-----------------
2138
Thomas Heller1b046642006-04-18 18:51:06 +00002139- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2140 by converting these apis from macros into exported functions again:
2141
2142 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2143 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2144 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
2145 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
2146 PyRun_String Py_CompileString
2147
Martin v. Löwis45294a92006-04-18 06:24:08 +00002148- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2149
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002150- All uses of PyStructSequence_InitType have been changed to initialize
2151 the type objects only once, even if the interpreter is initialized
2152 multiple times.
2153
Neal Norwitz61546162006-04-14 05:20:28 +00002154- Bug #1454485, array.array('u') could crash the interpreter. This was
2155 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2156 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2157
2158- Py_UNICODE is unsigned. It was always documented as unsigned, but
2159 due to a bug had a signed value in previous versions.
2160
Tim Peters3a5e8b12006-04-11 01:44:07 +00002161- Patch #837242: ``id()`` of any Python object always gives a positive
2162 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2163 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002164 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002165 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002166
Tim Peters3a5e8b12006-04-11 01:44:07 +00002167 def __hash__(self):
2168 return id(self) # WRONG
2169
2170 because a hash result must be a (short) Python int but it was always
2171 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002172 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002173 was always usable as a hash value before this patch. That's no longer
2174 necessarily so.
2175
2176- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002177 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002178 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002179 #1454844)
2180
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002181- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2182 involving generators that have paused outside of any ``try`` or ``with``
2183 blocks. (In 2.5a1, a paused generator that was part of a reference
2184 cycle could not be garbage collected, regardless of whether it was
2185 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00002186
Anthony Baxter51bcb682006-04-05 14:51:42 +00002187Extension Modules

Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00002190- Patch #1191065: Fix preprocessor problems on systems where recvfrom
2191 is a macro.
2192
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00002193- Bug #1467952: os.listdir() now correctly raises an error if readdir()
2194 fails with an error condition.
2195
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00002196- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
2197
2198- Bug #1117761: bsddb.*open() no longer raises an exception when using
2199 the cachesize parameter.
2200
2201- Bug #1149413: bsddb.*open() no longer raises an exception when using
2202 a temporary db (file=None) with the 'n' flag to truncate on open.
2203
2204- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
2205 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00002206
Armin Rigoa9017c32006-04-19 11:50:27 +00002207- Patch #1062014: AF_UNIX sockets under Linux have a special
2208 abstract namespace that is now fully supported.

2211-------
2212
Peter Astrand7d1d4362006-07-14 14:04:45 +00002213- Bug #1223937: subprocess.CalledProcessError reports the exit status
2214 of the process using the returncode attribute, instead of
2215 abusing errno.
2216
Tim Peters711bf302006-04-25 03:31:36 +00002217- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2218 a doctest to be skipped (the code is not run, and the expected output
2219 or exception is ignored).
2220
Nick Coghlanda2268f2006-04-24 04:37:15 +00002221- Fixed contextlib.nested to cope with exceptions being raised and
2222 caught inside exit handlers.
2223
Greg Wardab05edc2006-04-23 03:47:58 +00002224- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2225 hex, octal, or binary; add ``append_const`` action; keep going if
2226 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2227 added ``epilog`` for better help generation).
2228
Tim Peters21fbd572006-04-21 21:18:10 +00002229- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2230 called from a thread spawned as a side effect of importing a module.
2231
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002232- The pydoc module now supports documenting packages contained in
2233 .zip or .egg files.
2234
2235- The pkgutil module now has several new utility functions, such
2236 as ``walk_packages()`` to support working with packages that are either
2237 in the filesystem or zip files.
2238
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002239- The mailbox module can now modify and delete messages from
2240 mailboxes, in addition to simply reading them. Thanks to Gregory
2241 K. Johnson for writing the code, and to the 2005 Google Summer of
2242 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002243
Tim Petersc7605f22006-04-17 21:12:33 +00002244- The ``__del__`` method of class ``local`` in module ``_threading_local``
2245 returned before accomplishing any of its intended cleanup.
2246
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002247- Patch #790710: Add breakpoint command lists in pdb.
2248
Martin v. Löwis0db2a982006-04-16 20:55:38 +00002249- Patch #1063914: Add Tkinter.Misc.clipboard_get().

2252
Anthony Baxtere29002c2006-04-12 12:07:31 +00002253- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
2254 Windows. Bug #1469163.
2255
Phillip J. Eby47032112006-04-11 01:07:43 +00002256- The warnings, linecache, inspect, traceback, site, and doctest modules
2257 were updated to work correctly with modules imported from zipfiles or
2258 via other PEP 302 __loader__ objects.
2259
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00002260- Patch #1467770: Reduce usage of subprocess._active to processes which
2261 the application hasn't waited on.

2271-----
2272
Martin v. Löwis4be4e652006-04-17 19:25:49 +00002273- The Makefile now has a reindent target, which runs reindent.py on
2274 the library.
2275
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002276- Patch #1470875: Building Python with MS Free Compiler

Martin v. Löwis0f48d982006-04-14 14:34:26 +00002280- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2281 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002282 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002283 CXX from --with-cxx-main, see description in README.
2284
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002285- Patch #1429775: Link extension modules with the shared libpython.

Hye-Shik Changf4795c82006-04-26 19:20:26 +00002287- Fixed a libffi build problem on MIPS systems.
2288
Tim Peters8931ff12006-05-13 23:28:20 +00002289- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2290 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2291 and "%zu" for unsigned integers of type ``size_t``.
2292
Anthony Baxter51bcb682006-04-05 14:51:42 +00002293Tests
2294-----
2295
Nick Coghlanda2268f2006-04-24 04:37:15 +00002296- test_contextlib now checks contextlib.nested can cope with exceptions
2297 being raised and caught inside exit handlers.
2298
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002299- test_cmd_line now checks operation of the -m and -c command switches
2300
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002301- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2302 it separately and by hand. It also wasn't cleaning up its changes to
2303 the current Decimal context.
2304
Thomas Woutersabd08882006-04-26 15:53:30 +00002305- regrtest.py now has a -M option to run tests that test the new limits of
2306 containers, on 64-bit architectures. Running these tests is only sensible
2307 on 64-bit machines with more than two gigabytes of memory. The argument
2308 passed is the maximum amount of memory for the tests to use.

2320
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002321- PEP 343: Added Context Types section to the library reference
2322 and attempted to bring other PEP 343 related documentation into
2323 line with the implementation and/or python-dev discussions.
2324
Tim Peters8dc73d22006-04-24 02:03:16 +00002325- Bug #1337990: clarified that ``doctest`` does not support examples

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002334Core and builtins
2335-----------------
2336
Nick Coghlan43832302006-04-23 17:04:07 +00002337- PEP 338: -m command line switch now delegates to runpy.run_module
2338 allowing it to support modules in packages and zipfiles
2339
Martin v. Löwisc661b882006-04-20 04:54:23 +00002340- On Windows, .DLL is not an accepted file name extension for
2341 extension modules anymore; extensions are only found if they
2342 end in .PYD.
2343
Martin v. Löwisea62d252006-04-03 10:56:49 +00002344- Bug #1421664: sys.stderr.encoding is now set to the same value as
2345 sys.stdout.encoding.
2346
Neal Norwitz92e212f2006-04-03 04:48:37 +00002347- __import__ accepts keyword arguments.
2348
Georg Brandlccadf842006-03-31 18:54:53 +00002349- Patch #1460496: round() now accepts keyword arguments.
2350
Anthony Baxter262c00a2006-03-30 10:53:17 +00002351- Fixed bug #1459029 - unicode reprs were double-escaped.
2352
Hye-Shik Changd478f342006-03-23 12:32:36 +00002353- Patch #1396919: The system scope threads are reenabled on FreeBSD
2354 5.4 and later versions.
2355
Neal Norwitze98ccf62006-03-23 05:39:47 +00002356- Bug #1115379: Compiling a Unicode string with an encoding declaration
2357 now gives a SyntaxError.
2358
Georg Brandlabd1ff82006-03-18 07:59:59 +00002359- Previously, Python code had no easy way to access the contents of a
2360 cell object. Now, a ``cell_contents`` attribute has been added
2361 (closes patch #1170323).
2362
Tim Peterscf79aac2006-03-16 01:14:46 +00002363- Patch #1123430: Python's small-object allocator now returns an arena to
2364 the system ``free()`` when all memory within an arena becomes unused
2365 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2366 freed. Some applications will see a drop in virtual memory size now,
2367 especially long-running applications that, from time to time, temporarily
2368 use a large number of small objects. Note that when Python returns an
2369 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002370 platform C library will in turn return that memory to the operating system.
2371 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002372 appears to be effective at least on Microsoft C and gcc-based systems.
2373 Thanks to Evan Jones for hard work and patience.
2374
Georg Brandl533ff6f2006-03-08 18:09:27 +00002375- Patch #1434038: property() now uses the getter's docstring if there is
2376 no "doc" argument given. This makes it possible to legitimately use
2377 property() as a decorator to produce a read-only property.
2378
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002379- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2380 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2381 of requiring an int or long in slicing and a few other contexts, enabling
2382 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2383
Neal Norwitz995acdf2006-03-07 05:01:00 +00002384- Fixed various bugs reported by Coverity's Prevent tool.
2385
Brett Cannonbf364092006-03-01 04:25:17 +00002386- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2387 new exception base class, BaseException, which has a new message attribute.
2388 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2389 Raising a string exception now raises a DeprecationWarning.
2390
Thomas Woutersfb609f42006-02-28 16:37:25 +00002391- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2392 explicitly relative, using 'from .module import name' to mean 'from the same
2393 package as this module is in. Imports without dots still default to the
2394 old relative-then-absolute, unless 'from __future__ import
2395 absolute_import' is used.
2396
Brett Cannona7446e32006-02-27 23:39:10 +00002397- Properly check if 'warnings' raises an exception (usually when a filter set
2398 to "error" is triggered) when raising a warning for raising string
2399 exceptions.
2400
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002401- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002402 The name was removed from Include/code.h.
2403
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002404- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002405
Guido van Rossum1968ad32006-02-25 22:38:04 +00002406- Patch 1433928:
2407 - The copy module now "copies" function objects (as atomic objects).
2408 - dict.__getitem__ now looks for a __missing__ hook before raising
2409 KeyError.
2410
Tim Peters84ef21c2006-02-28 20:39:06 +00002411- PEP 343: with statement implemented. Needs ``from __future__ import
2412 with_statement``. Use of 'with' as a variable will generate a warning.
2413 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002414 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002415 The following objects have __context__ methods:
2416 - The built-in file type.
2417 - The thread.LockType type.
2418 - The following types defined by the threading module:
2419 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2420 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002421
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002422- Fix the encodings package codec search function to only search
2423 inside its own package. Fixes problem reported in patch #1433198.
2424
2425 Note: Codec packages should implement and register their own
2426 codec search function. PEP 100 has the details.
2427
Tim Peters9ea89d22006-06-04 03:26:02 +00002428- PEP 353: Using ``Py_ssize_t`` as the index type.
2429
2430- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2431 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2432 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2433 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2434 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002435
Neal Norwitzfc76d632006-01-10 06:03:13 +00002436- Patch #1400181, fix unicode string formatting to not use the locale.
2437 This is how string objects work. u'%f' could use , instead of .
2438 for the decimal point. Now both strings and unicode always use periods.
2439
Neal Norwitz671b9e32006-01-09 07:07:12 +00002440- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2441 configure would break checking curses.h.
2442
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002443- Bug #959576: The pwd module is now builtin. This allows Python to be
2444 built on UNIX platforms without $HOME set.
2445
Neal Norwitzc10978f2005-12-19 06:07:16 +00002446- Bug #1072182, fix some potential problems if characters are signed.
2447
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002448- Bug #889500, fix line number on SyntaxWarning for global declarations.
2449
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002450- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2451
Neal Norwitze7214a12005-12-18 05:03:17 +00002452- Support for converting hex strings to floats no longer works.
2453 This was not portable. float('0x3') now raises a ValueError.
2454
Barry Warsaw2a38a862005-12-18 01:27:35 +00002455- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002456 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002457 is now displayed in interactive prompt banner.
2458
Georg Brandlfa166682005-12-17 21:45:17 +00002459- Implementation of PEP 341 - Unification of try/except and try/finally.
2460 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002461 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002462
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002463- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2464 now encodes backslash correctly.
2465
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002466- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2467
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002468- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002469 and long longs.
2470
Neal Norwitz67715f02005-11-09 06:59:35 +00002471- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002472 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002473 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002474
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002475- Replaced most Unicode charmap codecs with new ones using the
2476 new Unicode translate string feature in the builtin charmap
2477 codec; the codecs were created from the mapping tables available
2478 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2479 encodings now include a mapping for the Apple logo)
2480
Tim Peterse3547fd2005-12-16 23:13:57 +00002481- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002482
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002483- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002484
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002485- A new AST parser implementation was completed. The abstract
2486 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002487 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002488
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002489- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002490 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2491
Neal Norwitz708e51a2005-10-03 04:48:15 +00002492- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2493
Neal Norwitz11bd1192005-10-03 00:54:56 +00002494- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2495 Provide a warning when a directory is passed on the command line.
2496
Neal Norwitz40d37812005-10-02 01:48:49 +00002497- Fix segfault with invalid coding.
2498
2499- SF bug #772896: unknown encoding results in MemoryError.
2500
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002501- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002502 supported a __len__() method which evaluated to False when the iterator
2503 was empty.
2504
Guido van Rossum630db602005-09-20 18:49:54 +00002505- On 64-bit platforms, when __len__() returns a value that cannot be
2506 represented as a C int, raise OverflowError.
2507
Skip Montanarof8948ca2005-09-19 03:54:46 +00002508- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002509 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002510
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002511- SF bug #893549: parsing keyword arguments was broken with a few format
2512 codes.
2513
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002514- Changes donated by Elemental Security to make it work on AIX 5.3
2515 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2516 bug #105470: test_pwd fails on 64bit system (Opteron).
2517
Guido van Rossum539c6622005-09-14 17:49:54 +00002518- Changes donated by Elemental Security to make it work on HP-UX 11 on
2519 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2520
Georg Brandl4550b8d2005-08-26 06:43:52 +00002521- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002522 (fixes bug #1119418).
2523
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002524- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2525
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002526- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2527 exceptions that cause a function to exit.
2528
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002529- The implementation of set() and frozenset() was revised to use its
2530 own internal data structure. Memory consumption is reduced by 1/3
2531 and there are modest speed-ups as well. The API is unchanged.
2532
Tim Petersde7990b2005-07-17 23:45:23 +00002533- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2534
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002535- SF bug #1229429: PyObject_CallMethod failed to decrement some
2536 reference counts in some error exit cases.
2537
Tim Petersecc6e6a2005-07-10 22:30:55 +00002538- SF bug #1185883: Python's small-object memory allocator took over
2539 a block managed by the platform C library whenever a realloc specified
2540 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002541 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002542 portable way to copy data from the C-managed block into Python's
2543 small-object space without risking a memory fault. Python's small-object
2544 realloc now leaves such blocks under the control of the platform C
2545 realloc.
2546
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002547- SF bug #1232517: An overflow error was not detected properly when
2548 attempting to convert a large float to an int in os.utime().
2549
Raymond Hettinger3296e692005-06-29 23:29:56 +00002550- SF bug #1224347: hex longs now print with lowercase letters just
2551 like their int counterparts.
2552
Michael W. Hudson188d4362005-06-20 16:52:57 +00002553- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2554 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2555 interpreter states; back out that fix and do a better job (see
2556 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2557 for a longer write-up of the problem).
2558
Michael W. Hudsondf888462005-06-03 14:41:55 +00002559- SF patch #1180995: marshal now uses a binary format by default when
2560 serializing floats.
2561
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002562- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2563 the routines that promise to produce IEEE 754 binary representations
2564 of floats now simply copy bytes around.
2565
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002566- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2567 278.
2568
Brett Cannonc3647ac2005-04-26 03:45:26 +00002569- patch #1109424: int, long, float, complex, and unicode now check for the
2570 proper magic slot for type conversions when subclassed. Previously the
2571 magic slot was ignored during conversion. Semantics now match the way
2572 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002573 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002574 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002575 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002576
Barry Warsawc8d907c2005-04-19 23:43:40 +00002577- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2578 NULL, now raise an AttributeError when attempting to set or delete the
2579 attribute. Previously a TypeError was raised, but this was inconsistent
2580 with the equivalent pure-Python implementation.
2581
Michael W. Hudson774479c2005-04-18 08:46:17 +00002582- It is now safe to call PyGILState_Release() before
2583 PyEval_InitThreads() (note that if there is reason to believe there
2584 are multiple threads around you still must call PyEval_InitThreads()
2585 before using the Python API; this fix is for extension modules that
2586 have no way of knowing if Python is multi-threaded yet).
2587
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002588- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2589 disabled caused a crash.
2590
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002591- Bug #1165306: instancemethod_new allowed the creation of a method
2592 with im_class == im_self == NULL, which caused a crash when called.
2593
Tim Petersecc6e6a2005-07-10 22:30:55 +00002594- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002595 fixes the crash seen in bug #1165761
2596

2637 calling __str__ on the argument returns a unicode instance.
2638
Tim Petersf4e69282006-02-27 17:15:31 +00002639- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2640 current thread state when the auto-GIL-state machinery knows about
2641 it (since the thread state is being deleted, continuing to remember it
2642 can't help, but can hurt if another thread happens to get created with
2643 the same thread id).

Nick Coghlan43832302006-04-23 17:04:07 +00002839- PEP 338: new module runpy defines a run_module function to support
2840 executing modules which provide access to source code or a code object
2841 via the PEP 302 import mechanisms.

2851 in attribute values.
2852
Anthony Baxterc51ee692006-04-01 00:57:31 +00002853- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002854 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002855 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002856 module will not be built.
2857
Tim Petersc17976e2006-04-01 00:26:53 +00002858- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2859 aren't officially supported here, and trying to use them will probably
2860 raise an exception some day. But dicts have been allowed, and "mostly

2881
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002882- email 4.0 package now integrated. This is largely the same as the email 3.0
2883 package that was included in Python 2.3, except that PEP 8 module names are
2884 now used (e.g. mail.message instead of email.Message). The MIME classes
2885 have been moved to a subpackage (e.g. email.mime.text instead of
2886 email.MIMEText). The old names are still supported for now. Several
2887 deprecated Message methods have been removed and lots of bugs have been
2888 fixed. More details can be found in the email package documentation.

2891 (a subclass of tuple) that provides incremental decoders and encoders
2892 (a way to use stateful codecs without the stream API). Python functions
2893 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2894 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2895 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002896

2898 a ValueError instead of a StopIteration now (like file and cString.String do).
2899 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2900 called before (like file and StringIO.StringIO do).

Tim Peterse3547fd2005-12-16 23:13:57 +00002974 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2975 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2976 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2977 Ronald L. Rivest offered this advice for Python:
2978
2979 "The consensus of researchers in this area (at least as
2980 expressed at the NIST Hash Function Workshop 10/31/05),
2981 is that SHA-256 is a good choice for the time being, but
2982 that research should continue, and other alternatives may
2983 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002984
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002985- Added a subset of Fredrik Lundh's ElementTree package. Available

3141
Raymond Hettingerbab41432005-02-05 01:31:19 +00003142- Fixed bug in a NameError bug in cookielib. Patch #1116583.
3143
Guido van Rossumd0641422005-02-03 15:01:24 +00003144- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
3145 disables recursive traversal through instance attributes, which can
3146 be exploited in various ways.
3147
Tim Peterse3547fd2005-12-16 23:13:57 +00003148- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00003149 flags on the HTTP listening socket.
3150
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00003151- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
3152 Fixed by reading the HTTP body in chunks instead of one big socket.read().
3153
Fred Drakefbdeaad2006-07-29 16:56:15 +00003154- Patches #893642, #1039083: add allow_none, encoding arguments to
3155 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00003156

3160
Martin v. Löwis22b457e2005-01-16 08:40:58 +00003161- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
3162
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003163- Enhancements to the csv module:
3164
3165 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003166 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003167 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003168 + Dialect parameter parsing has been re-implemented to improve error
3169 reporting.
3170 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3171 dictates.
3172 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003173 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003174 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003175 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3176 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003177 + reader now allows \r characters to be quoted (previously it only allowed
3178 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003179 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003180 + Dialect classes passed to the module are no longer instantiated by
3181 the module before being parsed (the former validation scheme required
3182 this, but the mechanism was unreliable).
3183 + The dialect registry now contains instances of the internal
3184 C-coded dialect type, rather than references to python objects.
3185 + the internal c-coded dialect type is now immutable.
3186 + register_dialect now accepts the same keyword dialect specifications
3187 as the reader and writer, allowing the user to register dialects
3188 without first creating a dialect class.
3189 + a configurable limit to the size of parsed fields has been added -
3190 previously, an unmatched quote character could result in the entire
3191 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003192 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003193 the parser field size limit (returning the former limit). The initial
3194 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003195 + A line_num attribute has been added to the reader object, which tracks
3196 the number of lines read from the source iterator. This is not
3197 the same as the number of records returned, as records can span
3198 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003199 + reader and writer objects were not being registered with the cyclic-GC.
3200 This has been fixed.
3201
Brett Cannone6539c42005-01-08 02:43:53 +00003202- _DummyThread objects in the threading module now delete self.__block that is
3203 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3204 lock primitives tend to be limited in number and thus should not be wasted on
3205 a _DummyThread object. Fixes bug #1089632.
3206
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003207- The imghdr module now detects Exif files.
3208
Raymond Hettinger6065d322004-12-20 23:51:53 +00003209- StringIO.truncate() now correctly adjusts the size attribute.
3210 (Bug #951915).
3211
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003212- locale.py now uses an updated locale alias table (built using
3213 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3214 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003215 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003216
Raymond Hettinger3557f422004-12-07 12:02:02 +00003217- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3218
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003219- the pickle module no longer accepts the deprecated None option in the
3220 args tuple returned by __reduce__().
3221
Brett Cannon84667c02004-12-07 03:25:18 +00003222- optparse now optionally imports gettext. This allows its use in setup.py.
3223
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003224- the pickle module no longer uses the deprecated bin parameter.
3225
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003226- the shelve module no longer uses the deprecated binary parameter.
3227
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003228- the pstats module no longer uses the deprecated ignore() method.
3229
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003230- the filecmp module no longer uses the deprecated use_statcache argument.
3231
Raymond Hettinger664347b2004-12-04 21:21:53 +00003232- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3233 extended or overridden by subclasses. Formerly, the subclassed method would
3234 be ignored by the rest of the module. (Bug #1078905).
3235
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003236- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003237 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003238
Walter Dörwald36733692004-12-22 12:50:50 +00003239- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3240 once when a size argument is given. This prevents a buffer overflow in the
3241 tokenizer with very long source lines.
3242
Barry Warsaw538561e2006-01-01 21:48:54 +00003243- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3244 immediately after creating the object, without any intervening
3245 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003246
Skip Montanaro05885812005-01-16 20:48:27 +00003247- The reconvert.quote function can now emit triple-quoted strings. The
3248 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003249
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003250- ``UserString.MutableString`` now supports negative indices in
3251 ``__setitem__`` and ``__delitem__``
3252
Greg Ward40407942005-03-05 02:53:17 +00003253- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3254 correctly.
3255
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003256- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3257 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3258 character even if the user has passed a size parameter to get a proper
3259 line ending. Remove the special handling of a "\r\n" that has been split
3260 between two lines.
3261
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003262- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3263 about illegal code points. The codec now supports PEP 293 style error
3264 handlers.
3265
Walter Dörwald78a78b02005-09-01 12:04:29 +00003266- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003267 from the input stream, so that the output is a byte string in the correct
3268 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003269
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003270- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3271 considering it exactly like a '*'.
3272
Walter Dörwald007f8df2005-10-09 19:42:27 +00003273- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3274 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003275
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003276- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3277
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003278- Patch #1413711: Certain patterns of differences were making difflib
3279 touch the recursion limit.
3280
Walter Dörwald58917a62006-03-31 15:26:22 +00003281- Bug #947906: An object oriented interface has been added to the calendar
3282 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003283 called as a script (e.g. via ``python -mcalendar``). Localized month and
3284 weekday names can be ouput (even if an exotic encoding is used) using
3285 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003286
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003287Build
3288-----
3289
Neal Norwitz602d3392006-03-31 08:21:40 +00003290- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3291 by using -mieee gcc option.
3292

3294
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003295- Build support for Win64-AMD64 was added.
3296
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003297- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3298
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003299- Patch #881820: look for openpty and forkpty also in libbsd.
3300
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003301- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3302 The zlib module is now builtin on Windows.
3303
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003304- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3305
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003306- Bug #1189330: configure did not correctly determine the necessary
3307 value of LINKCC if python was built with GCC 4.0.
3308
Trent Mick8321b422005-07-26 02:29:21 +00003309- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3310 vulnerability in zlib 1.2.1 and 1.2.2.
3311
Brett Cannon08cd5982005-04-24 22:26:38 +00003312- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3313 flags that change binary compatibility. Changes were also made to
3314 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003315 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003316
Bob Ippolitoed233462005-03-29 13:47:59 +00003317- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3318 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3319 no longer exists). This configure patch makes things right.
3320
Martin v. Löwise2713be2005-03-08 15:03:08 +00003321- Bug #1158607: Build with --disable-unicode again.
3322
Brett Cannon46d96232005-02-16 00:07:19 +00003323- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3324 defined. Discovered as a result of not being able to build on OS X.
3325
Brett Cannon516592f2004-12-07 00:42:59 +00003326- setup.py now uses the directories specified in LDFLAGS using the -L option
3327 and in CPPFLAGS using the -I option for adding library and include
3328 directories, respectively, for compiling extension modules against. This has
3329 led to the core being compiled using the values in CPPFLAGS. It also removes
3330 the need for the special-casing of both DarwinPorts and Fink for darwin since
3331 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3332 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3333 Fink, ``-I/opt/local/include`` for DarwinPorts).
3334
Brett Cannon43802422005-02-10 20:48:03 +00003335- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3336 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3337 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3338 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003340C API
3341-----
3342
Tim Petersc9d78aa2006-03-26 23:27:58 +00003343- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3344 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3345 is obtained via the ``PyObject_`` family, it must be released via the
3346 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3347 always been officially true, but when Python's small-object allocator was
3348 introduced, an attempt was made to cater to a few extension modules
3349 discovered at the time that obtained memory via ``PyObject_New`` but
3350 released it via ``PyMem_DEL``. It's years later, and if such code still
3351 exists it will fail now (probably with segfaults, but calling wrong
3352 low-level memory management functions can yield many symptoms).
3353
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003354- Added a C API for set and frozenset objects.
3355
Raymond Hettinger66517482004-12-03 11:45:13 +00003356- Removed PyRange_New().
3357
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003358- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3359 mapping argument now. This string is used as a mapping table. Byte values
3360 greater than the length of the string and 0xFFFE are treated as undefined
3361 mappings.
