45 method does not return iterators for the 4th and 5th items.
46
Amaury Forgeot d'Arcb50f9922008-09-26 22:46:01 +000047- Issue #3967: Fixed a crash in the count() and find() methods of string-like
48 objects, when the "start" parameter is a huge value.
49
Benjamin Petersond1c7d072008-09-25 20:46:05 +000050- Issue #3936: The parser warnings for using "as" and "with" as variable names

Neal Norwitz83ac0142008-07-28 05:06:20 +000061- Issue #2620: Overflow checking when allocating or reallocating memory
62 was not always being done properly in some python types and extension
63 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
64 all been updated to perform better checks and places in the code that
65 would previously leak memory on the error path when such an allocation
66 failed have been fixed.

75 set to a custom object whose write() method happens to install
76 another file in sys.stdout.
77
Amaury Forgeot d'Arcb15bdf72008-07-01 20:59:49 +000078- Issue #3088: Corrected a race condition in classes derived from

84
Guido van Rossumaa975432008-04-10 22:43:58 +000085- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
86 having a self-referential tuple, which is possible from C code. Nor did
87 object's tp_str consider that a type's tp_str could do something that could
88 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
89 respectively, fixed the issues. (Backport of r58288 from trunk.)
90

95 reference on the outer class name.
96
Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +000097- Issue #1477: With narrow Unicode builds, the unicode escape sequence
98 \Uxxxxxxxx did not accept values outside the Basic Multilingual Plane. This
99 affected raw unicode literals and the 'raw-unicode-escape' codec. Now
100 UTF-16 surrogates are generated in this case, like normal unicode literals
101 and the 'unicode-escape' codec.
102
Neal Norwitzb3635f92008-03-18 04:17:36 +0000103- Issue #2321: use pymalloc for unicode object string data to reduce
104 memory usage in some circumstances.
Andrew M. Kuchlingbe0adfc2008-02-23 17:18:19 +0000105
Sean Reifscheider4af861c2008-03-20 17:39:31 +0000106- Issue #2238: Some syntax errors in *args and **kwargs expressions could give

110 parameter but was not verifying that it was greater than zero. Values
111 less than zero will now raise a SystemError and return NULL to indicate a
112 bug in the calling C code.
113
Gregory P. Smith9aa040d2008-06-02 00:07:25 +0000114- Issue #2588, #2589: Fix potential integer underflow and overflow
115 conditions in the PyOS_vsnprintf C API function.
116
Gregory P. Smithcae7f882008-09-07 06:44:12 +0000117- Issue #1204: The configure script now tests for additional libraries
118 that may be required when linking against readline. This fixes issues
119 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
Georg Brandld9f1da02008-03-29 01:50:46 +0000120
Gregory P. Smitha7a94a02008-09-22 00:22:44 +0000121- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
122 library targets in the Makefile.

Amaury Forgeot d'Arc22679b82008-08-18 19:33:42 +0000160- Issue #2234: distutils failed for some versions of the cygwin compiler. The
161 version reported by these tools does not necessarily follow the python
162 version numbering scheme, so the module is less strict when parsing it.
163
Hirokazu Yamamoto1d63a452008-08-17 09:49:10 +0000164- Issue #2222: Fixed reference leak when occured os.rename()

1154 allows calling unicode() on exceptions classes directly to succeed.
1155
Georg Brandlecab6232006-09-06 06:47:02 +00001156- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
1157 Also make sure that every exception class has __module__ set to
1158 'exceptions'.
1159
Georg Brandl37a9e572006-09-06 06:09:34 +00001160- Bug #1550983: emit better error messages for erroneous relative
1161 imports (if not in package and if beyond toplevel package).
1162

1170
Neal Norwitz29a5fdb2006-09-05 02:21:38 +00001171- The return tuple from str.rpartition(sep) is (tail, sep, head) where
1172 head is the original string if sep was not found.
1173
Neal Norwitz3b3aae02006-09-05 03:56:01 +00001174- Bug #1520864: unpacking singleton tuples in list comprehensions and
1175 generator expressions (x for x, in ... ) works again. Fixing this problem
1176 required changing the .pyc magic number. This means that .pyc files
1177 generated before 2.5c2 will be regenerated.

1289Core and builtins
1290-----------------
1291
Neal Norwitz24b6f202006-09-05 04:43:56 +00001292- Fix infinite recursion when subclassing long and overriding __hash__.
1293
1294- Fix concatenation (+=) of long strings.
1295
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001296- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001297 compared equal or unequal to a string and a UnicodeDecodeError
1298 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001299
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001300 Instead, the equal (==) and unequal (!=) comparison operators will
1301 now issue a UnicodeWarning and interpret the two objects as
1302 unequal. The UnicodeWarning can be filtered as desired using
1303 the warning framework, e.g. silenced completely, turned into an
1304 exception, logged, etc.
1305
1306 Note that compare operators other than equal and unequal will still
1307 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001308
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001309- Fix segfault when doing string formatting on subclasses of long.
1310
1311- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1312 with new-style classes.
1313
1314- Fix bug related to __len__ functions returning negative values with
1315 classic classes.
1316
1317- Patch #1538606, Fix __index__() clipping. There were some problems
1318 discovered with the API and how integers that didn't fit into Py_ssize_t
1319 were handled. This patch attempts to provide enough alternatives
1320 to effectively use __index__.
1321
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001322- Bug #1536021: __hash__ may now return long int; the final hash
1323 value is obtained by invoking hash on the long int.
1324
Thomas Hellerab1049c2006-08-08 17:37:00 +00001325- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1326
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001327- Bug #1535165: fixed a segfault in input() and raw_input() when
1328 sys.stdin is closed.
1329
Thomas Heller74d36f02006-08-04 18:17:40 +00001330- On Windows, the PyErr_Warn function is now exported from
1331 the Python dll again.
1332
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001333- Bug #1191458: tracing over for loops now produces a line event
1334 on each iteration. Fixing this problem required changing the .pyc
1335 magic number. This means that .pyc files generated before 2.5c1
1336 will be regenerated.
1337
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001338- Bug #1333982: string/number constants were inappropriately stored
1339 in the byte code and co_consts even if they were not used, ie
1340 immediately popped off the stack.
1341
Georg Brandle9462c72006-08-04 18:03:37 +00001342- Fixed a reference-counting problem in property().

1345Library
1346-------
1347
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001348- Fix a bug in the ``compiler`` package that caused invalid code to be
1349 generated for generator expressions.
1350
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001351- The distutils version has been changed to 2.5.0. The change to
1352 keep it programmatically in sync with the Python version running
1353 the code (introduced in 2.5b3) has been reverted. It will continue
1354 to be maintained manually as static string literal.
1355
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001356- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001357 and this cannot be converted to the required C type, an exception is
1358 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001359 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001360
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001361- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001362 an exception.
1363
Tim Peterscbdd3502006-09-05 01:47:53 +00001364- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001365 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001366 workarounds for clocks with low resolution, to stop the code yielding
1367 duplicate UUIDs.
1368
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001369- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1370 before raising SystemExit, allowing IDLE to honor quit() and exit().
1371
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001372- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1373
Georg Brandl7a1af772006-08-14 21:55:28 +00001374- Patch #1536071: trace.py should now find the full module name of a
1375 file correctly even on Windows.
1376
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001377- logging's atexit hook now runs even if the rest of the module has
1378 already been cleaned up.
1379
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001380- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001381
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001382- Bug #1531405, format_exception no longer raises an exception if
1383 str(exception) raised an exception.
1384
Neil Schemenauer06ded092006-08-04 16:20:30 +00001385- Fix a bug in the ``compiler`` package that caused invalid code to be
1386 generated for nested functions.

1403 uses the _as_parameter_ attribute when objects are passed to foreign
1404 function calls. The ctypes version number was changed to 1.0.1.
1405
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001406- Bug #1530559, struct.pack raises TypeError where it used to convert.
1407 Passing float arguments to struct.pack when integers are expected
1408 now triggers a DeprecationWarning.

Tim Peters4643c2f2006-08-10 22:45:34 +00001447- Bug #1069160. Internal correctness changes were made to
1448 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1449 the documentation was changed to state that the return value
1450 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001453What's New in Python 2.5 beta 3?
1454================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001455
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001456*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001457
1458Core and builtins
1459-----------------
1460
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001461- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001462 returned a long (see PEP 353).
1463
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001464- Bug #1515471: string.replace() accepts character buffers again.
1465
Neal Norwitz07aadb12006-07-30 06:55:48 +00001466- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1467 This provides the proper warning for struct.pack().
1468 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1469
Neal Norwitz0d62a062006-07-30 06:53:31 +00001470- Patch #1531113: Fix augmented assignment with yield expressions.
1471 Also fix a SystemError when trying to assign to yield expressions.
1472
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001473- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1474 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1475 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1476 excessive filesystem operations during imports.
1477
Tim Petersbc24eee2006-07-27 01:14:53 +00001478- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1479 operations on signed longs that are formally undefined by C.
1480 Unfortunately, at least one compiler now cares about that, so complicated
1481 the code to make that compiler happy again.
1482
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001483- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1484
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001485- Patch #1232023: Stop including current directory in search
1486 path on Windows.
1487
Neal Norwitze1fdb322006-07-21 05:32:28 +00001488- Fix some potential crashes found with failmalloc.
1489
Neal Norwitze7563102006-07-17 01:00:16 +00001490- Fix warnings reported by Klocwork's static analysis tool.
1491
Neal Norwitz84be93b2006-07-16 01:50:38 +00001492- Bug #1512814, Fix incorrect lineno's when code within a function
1493 had more than 255 blank lines.
1494
Georg Brandl9dceedb2006-07-12 15:31:17 +00001495- Patch #1521179: Python now accepts the standard options ``--help`` and
1496 ``--version`` as well as ``/?`` on Windows.
1497
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001498- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001499 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001500 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001501
Tim Peters112aad32006-07-19 00:03:19 +00001502- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001503 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001504 new ``sys._current_frames()`` returns a dictionary with one entry,
1505 mapping the faux "thread id" 0 to the current frame.
1506
Ronald Oussoren3075e162006-07-25 20:28:55 +00001507- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001508
Ronald Oussoren3075e162006-07-25 20:28:55 +00001509
Neal Norwitza1f10902006-07-12 07:28:29 +00001510Library
1511-------
1512
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001513- Correction of patch #1455898: In the mbcs decoder, set final=False
1514 for stream decoder, but final=True for the decode function.
1515
Georg Brandl07fec3a2006-08-01 18:49:24 +00001516- os.urandom no longer masks unrelated exceptions like SystemExit or
1517 KeyboardInterrupt.
1518
Tim Peters4643c2f2006-08-10 22:45:34 +00001519- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001520 shutil.copytree on Windows
1521
Georg Brandle34ac7c2006-07-30 11:07:23 +00001522- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1523 refers to file descriptors, not file objects.
1524
Tim Peterscbdd3502006-09-05 01:47:53 +00001525- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001526 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001527 #1513611, and probably others.
1528
Georg Brandledd9b0d2006-07-29 09:33:26 +00001529- Bug #1441397: The compiler module now recognizes module and function
1530 docstrings correctly as it did in Python 2.4.
1531
Tim Peters6f681472006-07-27 23:44:37 +00001532- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1533 lost that tests are sorted by name before being run. This rarely
1534 matters for well-written tests, but can create baffling symptoms if
1535 side effects from one test to the next affect outcomes. ``DocTestFinder``
1536 has been changed to sort the list of tests it returns.
1537
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001538- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001539 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001540
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001541- Bug #978833: Really close underlying socket in _socketobject.close.
1542
Georg Brandldb232dc2006-08-20 13:15:43 +00001543- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1544 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001545
Georg Brandlcf0c1722006-07-26 07:23:32 +00001546- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1547 to recursive calls and call it with the failing package name.
1548
Martin v. Löwis0b483032006-07-25 09:53:12 +00001549- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1550
Georg Brandlc13c34c2006-07-24 14:09:56 +00001551- Patch #1515343: Fix printing of deprecated string exceptions with a
1552 value in the traceback module.
1553
Greg Ward48fae7a2006-07-23 16:05:51 +00001554- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1555
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001556- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1557
Brett Cannoncaebe222006-07-18 04:41:36 +00001558- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1559 argument tuple. For arguments where zero is illegal, the value is forced to
1560 the minimum value that is correct. This is to support an undocumented but
1561 common way people used to fill in inconsequential information in the time
1562 tuple pre-2.4.
1563
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001564- Patch #1220874: Update the binhex module for Mach-O.
1565
Barry Warsawb110bad2006-07-21 14:51:07 +00001566- The email package has improved RFC 2231 support, specifically for
1567 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1568 (name*0=<blah>) parameter continuations. This may change the types of
1569 values returned from email.message.Message.get_param() and friends.
1570 Specifically in some cases where non-encoded continuations were used,
1571 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1572 will just return the string (since non-encoded continuations don't have
1573 charset and language parts).
1574
1575 Also, whereas % values were decoded in all parameter continuations, they are
1576 now only decoded in encoded parameter parts.
1577
Ronald Oussoren3075e162006-07-25 20:28:55 +00001578- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1579
1580- Bug #1517996: IDLE now longer shows the default Tk menu when a
1581 path browser, class browser or debugger is the frontmost window on MacOS X
1582
Barry Warsaw00decd72006-07-27 23:43:15 +00001583- Patch #1520294: Support for getset and member descriptors in types.py,
1584 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1585 of an object against these built-in types and more importantly, for getting
1586 their docstrings printed in the interactive interpreter's help() function.
1587
Ronald Oussoren3075e162006-07-25 20:28:55 +00001588
Neal Norwitza1f10902006-07-12 07:28:29 +00001589Extension Modules
1590-----------------
1591
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001592- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1593 a socket operation on a socket with a timeout, the exception will be
1594 caught correctly. Previously, the exception was not caught.
1595
Thomas Heller1393d6a2006-07-28 21:43:20 +00001596- Patch #1529514: The _ctypes extension is now compiled on more
1597 openbsd target platforms.
1598
Tim Peters9cab5932006-07-28 00:30:00 +00001599- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1600 a memory leak, affecting pickles and deep copies.
1601
Tim Petersbc24eee2006-07-27 01:14:53 +00001602- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001603 Paul Eggert.
1604
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001605- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1606
Thomas Hellerce049a02006-07-14 17:51:14 +00001607- Patch #1521817: Index range checking on ctypes arrays containing
1608 exactly one element enabled again. This allows iterating over these
1609 arrays, without the need to check the array size before.
1610
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001611- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001612 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001613 /dev/null in certain cases; this is now fixed.
1614
Thomas Heller47d7a062006-07-12 08:43:47 +00001615- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1616 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001617
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001618- Because of a misspelled preprocessor symbol, ctypes was always
1619 compiled without thread support; this is now fixed.
1620
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001621- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1622 methods now allow their database parameter to be None as the
1623 sleepycat API allows.
1624
Matt Flemingec926502006-07-28 11:27:27 +00001625- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1626 bluetooth API compared with Linux and FreeBSD.
1627
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001628Tests
1629-----
1630
1631- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1632 how long the test file should take to play. Now accepts taking 2.93 secs
1633 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1634
Georg Brandl4793aa32006-07-28 18:31:39 +00001635- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1636 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1637 run via ``regrtest.py``. Now they do.
Tim Peters3e246a82006-07-27 15:09:20 +00001638
Martin v. Löwis0907f4d2006-07-30 14:09:47 +00001639Build

Ronald Oussoren26cad082006-08-01 21:00:57 +00001644Mac
1645---
1646
1647- PythonLauncher now works correctly when the path to the script contains
1648 characters that are treated specially by the shell (such as quotes).
1649
1650- Bug #1527397: PythonLauncher now launches scripts with the working directory
1651 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001652 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001653 expect.

1662-----------------
1663
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001664- Bug #1441486: The literal representation of -(sys.maxint - 1)
1665 again evaluates to a int object, not a long.
1666
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001667- Bug #1501934: The scope of global variables that are locally assigned
1668 using augmented assignment is now correctly determined.
1669
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001670- Bug #927248: Recursive method-wrapper objects can now safely
1671 be released.
1672
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001673- Bug #1417699: Reject locale-specific decimal point in float()
1674 and atof().
1675
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001676- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1677 omit a default "error" argument for NULL pointer. This allows
1678 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001679
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001680- Bug #1519018: 'as' is now validated properly in import statements.
1681
Neal Norwitz28746ab2006-07-09 22:14:42 +00001682- On 64 bit systems, int literals that use less than 64 bits are
1683 now ints rather than longs.
1684
Neal Norwitzed657552006-07-10 00:04:44 +00001685- Bug #1512814, Fix incorrect lineno's when code at module scope
1686 started after line 256.
1687
Tim Peters32a83612006-07-10 21:08:24 +00001688- New function ``sys._current_frames()`` returns a dict mapping thread
1689 id to topmost thread stack frame. This is for expert use, and is
1690 especially useful for debugging application deadlocks. The functionality
1691 was previously available in Fazal Majid's ``threadframe`` extension
1692 module, but it wasn't possible to do this in a wholly threadsafe way from
1693 an extension.

Martin v. Löwis77621582006-07-30 13:27:31 +00001698- Bug #1257728: Mention Cygwin in distutils error message about a missing
1699 VS 2003.
1700
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001701- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1702
Tim Peters32a83612006-07-10 21:08:24 +00001703- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001704 environment variable to be set in order to the SDK environment
1705 for finding the compiler, include files, etc.

Martin v. Löwis388a8c22006-07-06 19:28:03 +00001707- Bug #1515998: Properly generate logical ids for files in bdist_msi.
1708
Nick Coghlan2d792252006-07-06 13:47:18 +00001709- warnings.py now ignores ImportWarning by default
1710
Thomas Woutersadd19112006-07-05 11:03:49 +00001711- string.Template() now correctly handles tuple-values. Previously,
1712 multi-value tuples would raise an exception and single-value tuples would
1713 be treated as the value they contain, instead.
1714
Martin v. Löwisede77f52006-07-03 13:01:35 +00001715- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1716 even if some data are received.
1717
Martin v. Löwis45482392006-07-03 12:28:58 +00001718- Bug #1267547: Put proper recursive setup.py call into the
1719 spec file generated by bdist_rpm.
1720
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001721- Bug #1514693: Update turtle's heading when switching between
1722 degrees and radians.
1723

Martin v. Löwis2b88f632006-07-03 10:19:49 +00001725 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001726
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001727- Bug #1514703: Only setup canvas window in turtle when the canvas
1728 is created.
1729
Martin v. Löwis7596e832006-07-01 15:33:37 +00001730- Bug #1513223: .close() of a _socketobj now releases the underlying
1731 socket again, which then gets closed as it becomes unreferenced.
1732
Fred Drake10497c82006-06-29 02:57:48 +00001733- Bug #1504333: Make sgmllib support angle brackets in quoted
1734 attribute values.
1735
1736- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1737 sgmllib ('[' and ']' were not accepted).
1738
Georg Brandl1be63af2006-06-28 20:23:25 +00001739- Fix a bug in the turtle module's end_fill function.
1740
Brett Cannon53ab5b72006-06-22 16:49:14 +00001741- Bug #1510580: The 'warnings' module improperly required that a Warning
1742 category be either a types.ClassType and a subclass of Warning. The proper
1743 check is just that it is a subclass with Warning as the documentation states.
1744
Georg Brandlad29e632006-06-21 17:45:17 +00001745- The compiler module now correctly compiles the new try-except-finally
1746 statement (bug #1509132).
1747
Neal Norwitz60373cd2006-06-22 06:30:50 +00001748- The wsgiref package is now installed properly on Unix.
1749
Vinay Sajip28e57612006-07-01 10:45:20 +00001750- A bug was fixed in logging.config.fileConfig() which caused a crash on
1751 shutdown when fileConfig() was called multiple times.
1752
Gerhard Häring762fbd32006-07-02 17:48:30 +00001753- The sqlite3 module did cut off data from the SQLite database at the first
1754 null character before sending it to a custom converter. This has been fixed
1755 now.
1756
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001757Extension Modules
1758-----------------
1759
Tim Peters112aad32006-07-19 00:03:19 +00001760- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1761 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1762 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001763
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001764- Assigning None to pointer type fields in ctypes structures possible
1765 overwrote the wrong fields, this is fixed now.
1766
1767- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1768 on non-Windows platforms.
1769
1770- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1771 integer or long, without range checking.
1772
1773- Patch #1517790: It is now possible to use custom objects in the ctypes
1774 foreign function argtypes sequence as long as they provide a from_param
1775 method, no longer is it required that the object is a ctypes type.
1776
1777- The '_ctypes' extension module now works when Python is configured
1778 with the --without-threads option.
1779
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001780- Bug #1513646: os.access on Windows now correctly determines write
1781 access, again.
1782
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001783- Bug #1512695: cPickle.loads could crash if it was interrupted with
1784 a KeyboardInterrupt.
1785
Neal Norwitza12aa882006-07-06 06:45:08 +00001786- Bug #1296433: parsing XML with a non-default encoding and
1787 a CharacterDataHandler could crash the interpreter in pyexpat.
1788

1795
Tim Peters32a83612006-07-10 21:08:24 +00001796- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001797 Previously, the slight difference could cause compilation errors of the
1798 'zlib' module on systems with more than one version of zlib.
1799
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001800- The MSI compileall step was fixed to also support a TARGETDIR

Anthony Baxter51bcb682006-04-05 14:51:42 +00001830
1831Core and builtins
1832-----------------
1833
Georg Brandla56b9152006-06-19 06:35:54 +00001834- Patch #1507676: Error messages returned by invalid abstract object operations
1835 (such as iterating over an integer) have been improved and now include the
1836 type of the offending object to help with debugging.
1837
Brett Cannonea3912b2006-06-13 21:46:41 +00001838- Bug #992017: A classic class that defined a __coerce__() method that returned
1839 its arguments swapped would infinitely recurse and segfault the interpreter.
1840
Neal Norwitz909eb122006-06-12 02:13:21 +00001841- Fix the socket tests so they can be run concurrently.
1842
Neal Norwitzb9845e72006-06-12 02:11:18 +00001843- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001844 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001845
Brett Cannon22565aa2006-06-09 22:31:23 +00001846- Bug #532646: object.__call__() will continue looking for the __call__
1847 attribute on objects until one without one is found. This leads to recursion
1848 when you take a class and set its __call__ attribute to an instance of the
1849 class. Originally fixed for classic classes, but this fix is for new-style.
1850 Removes the infinite_rec_3 crasher.
1851
Georg Brandl24250812006-06-09 18:45:48 +00001852- The string and unicode methods startswith() and endswith() now accept
1853 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1854
Brett Cannonde3b0522006-06-08 17:00:45 +00001855- Buffer objects, at the C level, never used the char buffer
1856 implementation even when the char buffer for the wrapped object was
1857 explicitly requested (originally returned the read or write buffer).
1858 Now a TypeError is raised if the char buffer is not present but is
1859 requested.
1860
Georg Brandlddbaa662006-06-04 21:56:52 +00001861- Patch #1346214: Statements like "if 0: suite" are now again optimized
1862 away like they were in Python 2.4.
1863
Georg Brandlb7c8f542006-05-27 12:30:25 +00001864- Builtin exceptions are now full-blown new-style classes instead of
1865 instances pretending to be classes, which speeds up exception handling
1866 by about 80% in comparison to 2.5a2.
1867
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001868- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1869 Unicode 4.1.
1870
Georg Brandlf4ef1162006-05-26 18:03:31 +00001871- Patch #921466: sys.path_importer_cache is now used to cache valid and
1872 invalid file paths for the built-in import machinery which leads to
1873 fewer open calls on startup.
1874
Tim Peters696cf432006-05-24 21:10:40 +00001875- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1876 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1877 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1878 the number of input digits (it was and remains linear-time for bases
1879 2, 4, 8, 16 and 32).
1880
Tim Petersb713ec22006-05-23 18:45:30 +00001881- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1882 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1883 an integer close to ``sys.maxint``. This was repaired by patch
1884 #1335972, which also gives a nice speedup.
1885
Richard Jonescebbefc2006-05-23 18:28:17 +00001886- Patch #1337051: reduced size of frame objects.
1887
1888- PyErr_NewException now accepts a tuple of base classes as its
1889 "base" parameter.
1890
Richard Jones7c88dcc2006-05-23 10:37:38 +00001891- Patch #876206: function call speedup by retaining allocated frame
1892 objects.
1893
Georg Brandl7b90e162006-05-18 07:01:27 +00001894- Bug #1462152: file() now checks more thoroughly for invalid mode
1895 strings and removes a possible "U" before passing the mode to the
1896 C library function.
1897
Neal Norwitz1004a532006-05-15 07:17:23 +00001898- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1899
Neal Norwitz373f0a72006-05-15 07:04:36 +00001900- Bug #1487966: Fix SystemError with conditional expression in assignment
1901
Martin v. Löwis879768d2006-05-11 13:28:43 +00001902- WindowsError now has two error code attributes: errno, which carries
1903 the error values from errno.h, and winerror, which carries the error
1904 values from winerror.h. Previous versions put the winerror.h values
1905 (from GetLastError()) into the errno attribute.
1906
Martin v. Löwis77736712006-05-04 05:51:03 +00001907- Patch #1475845: Raise IndentationError for unexpected indent.
1908
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001909- Patch #1479181: split open() and file() from being aliases for each other.
1910
Tim Peters44bd9862006-06-01 13:49:23 +00001911- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1912 methods were always silently ignored by dictionaries when comparing keys.
1913 They are now passed through (except when using the C API function
1914 ``PyDict_GetItem()``, whose semantics did not change).
1915
1916- Bug #1456209: In some obscure cases it was possible for a class with a
1917 custom ``__eq__()`` method to confuse dict internals when class instances
1918 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1919 No, you don't have any code that did this ;-)

1932
Nick Coghlanc649ec52006-05-29 12:43:05 +00001933- Patch #1478788 (modified version): The functional extension module has
1934 been renamed to _functools and a functools Python wrapper module added.
1935 This provides a home for additional function related utilities that are
1936 not specifically about functional programming. See PEP 309.
1937
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001938- Patch #1493701: performance enhancements for struct module.

1946 enabled builds on Windows and systems with Posix threads support.
1947
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001948- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1949 (up to the system limit of 32K characters).
1950
1951- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1952 As a result, these functions now raise WindowsError instead of OSError.
1953
Tim Peters7a822da2006-05-25 21:50:17 +00001954- ``time.clock()`` on Win64 should use the high-performance Windows
1955 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1956 Windows platforms).
1957
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001958- Calling Tk_Init twice is refused if the first call failed as that
1959 may deadlock.
1960
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001961- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1962 accept it without potentially using an uninitialized pointer.
1963
1964- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1965 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

1975 results. It could previously incorrectly return 0 in some cases.
1976 Fixes SF bug 1493322 (pybsddb bug 1184012).
1977
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001978- bsddb: the bsddb.dbtables Modify method now raises the proper error and

1980 Fixes SF python patch/bug #1408584.
1981
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001982- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001983 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001984 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1985 database calls that would previously deadlock. [SF python bug #775414]

Martin v. Löwisd8251432006-06-14 05:21:04 +00002014- Patch #1455898: The MBCS codec now supports the incremental mode for
2015 double-byte encodings.
2016
Tim Peters43898b42006-06-14 04:09:25 +00002017- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
2018 guarantee that adjacent triples in the return list always describe
2019 non-adjacent blocks. Previously, a pair of matching blocks could end
2020 up being described by multiple adjacent triples that formed a partition
2021 of the matching pair.
2022
Greg Ward0e0c9f42006-06-11 16:24:11 +00002023- Bug #1498146: fix optparse to handle Unicode strings in option help,
2024 description, and epilog.
2025
Greg Wardd1c797e2006-06-11 14:42:41 +00002026- Bug #1366250: minor optparse documentation error.
2027
Greg Ward7f547402006-06-11 00:40:49 +00002028- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
2029 clarify docs.
2030
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00002031- The wsgiref package has been added to the standard library.
2032
Nick Coghlan676725d2006-06-08 13:54:49 +00002033- The functions update_wrapper() and wraps() have been added to the functools
2034 module. These make it easier to copy relevant metadata from the original
2035 function when writing wrapper functions.
2036
Tim Petersd6a9eef2006-06-05 01:48:21 +00002037- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
2038 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00002039
Martin v. Löwis3f767792006-06-04 19:36:28 +00002040- Patch #1359618: Speed up charmap encoder by using a trie structure
2041 for lookup.
2042
Tim Petersd609b1a2006-06-02 23:22:51 +00002043- The functions in the ``pprint`` module now sort dictionaries by key
2044 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
2045 if and only if its display required more than one line, although that
2046 wasn't documented. The new behavior increases predictability; e.g.,
2047 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
2048
Georg Brandlfd9a4b12006-05-29 20:57:01 +00002049- Patch #1497027: try HTTP digest auth before basic auth in urllib2
2050 (thanks for J. J. Lee).
2051
Georg Brandl2b330372006-05-28 20:23:12 +00002052- Patch #1496206: improve urllib2 handling of passwords with respect to
2053 default HTTP and HTTPS ports.
2054
George Yoshidaf3c65de2006-05-28 16:39:09 +00002055- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
2056
Bob Ippolito7298f272006-05-23 18:43:47 +00002057- Patch #1281707: speed up gzip.readline.
2058
Georg Brandlb89316f2006-05-17 15:51:16 +00002059- Patch #1180296: Two new functions were added to the locale module:
2060 format_string() to get the effect of "format % items" but locale-aware,
2061 and currency() to format a monetary number with currency sign.
2062
Georg Brandle3a25832006-05-17 14:56:04 +00002063- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
2064 and several features added, such as speed and geometry control.
2065
Georg Brandl49c8f4c2006-05-15 19:30:35 +00002066- Patch #1488881: add support for external file objects in bz2 compressed
2067 tarfiles.
2068
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002069- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
2070 stdout arguments, making it possible to redirect input and output
2071 for remote debugging.
2072
2073- Patch #1484695: Update the tarfile module to version 0.8. This fixes
2074 a couple of issues, notably handling of long file names using the
2075 GNU LONGNAME extension.
2076
2077- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
2078 new flag when ``name`` is already the name of an option flag.
2079
2080- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
2081 package.
2082
2083- Patch #1472854: make the rlcompleter.Completer class usable on non-
2084 UNIX platforms.
2085
2086- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
2087
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00002088- Bug #1472827: correctly escape newlines and tabs in attribute values in
2089 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00002119What's New in Python 2.5 alpha 2?
2120=================================
2121
2122*Release date: 27-APR-2006*
2123
2124Core and builtins
2125-----------------
2126
Thomas Heller1b046642006-04-18 18:51:06 +00002127- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2128 by converting these apis from macros into exported functions again:
2129
2130 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2131 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2132 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
2133 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
2134 PyRun_String Py_CompileString
2135
Martin v. Löwis45294a92006-04-18 06:24:08 +00002136- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2137
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002138- All uses of PyStructSequence_InitType have been changed to initialize
2139 the type objects only once, even if the interpreter is initialized
2140 multiple times.
2141
Neal Norwitz61546162006-04-14 05:20:28 +00002142- Bug #1454485, array.array('u') could crash the interpreter. This was
2143 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2144 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2145
2146- Py_UNICODE is unsigned. It was always documented as unsigned, but
2147 due to a bug had a signed value in previous versions.
2148
Tim Peters3a5e8b12006-04-11 01:44:07 +00002149- Patch #837242: ``id()`` of any Python object always gives a positive
2150 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2151 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002152 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002153 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002154
Tim Peters3a5e8b12006-04-11 01:44:07 +00002155 def __hash__(self):
2156 return id(self) # WRONG
2157
2158 because a hash result must be a (short) Python int but it was always
2159 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002160 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002161 was always usable as a hash value before this patch. That's no longer
2162 necessarily so.
2163
2164- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002165 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002166 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002167 #1454844)
2168
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002169- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2170 involving generators that have paused outside of any ``try`` or ``with``
2171 blocks. (In 2.5a1, a paused generator that was part of a reference
2172 cycle could not be garbage collected, regardless of whether it was
2173 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00002174
Anthony Baxter51bcb682006-04-05 14:51:42 +00002175Extension Modules

2180
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00002181- Bug #1467952: os.listdir() now correctly raises an error if readdir()
2182 fails with an error condition.
2183
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00002184- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
2185
2186- Bug #1117761: bsddb.*open() no longer raises an exception when using
2187 the cachesize parameter.
2188
2189- Bug #1149413: bsddb.*open() no longer raises an exception when using
2190 a temporary db (file=None) with the 'n' flag to truncate on open.
2191
2192- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
2193 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00002194
Armin Rigoa9017c32006-04-19 11:50:27 +00002195- Patch #1062014: AF_UNIX sockets under Linux have a special
2196 abstract namespace that is now fully supported.

2202 of the process using the returncode attribute, instead of
2203 abusing errno.
2204
Tim Peters711bf302006-04-25 03:31:36 +00002205- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2206 a doctest to be skipped (the code is not run, and the expected output
2207 or exception is ignored).
2208
Nick Coghlanda2268f2006-04-24 04:37:15 +00002209- Fixed contextlib.nested to cope with exceptions being raised and
2210 caught inside exit handlers.
2211
Greg Wardab05edc2006-04-23 03:47:58 +00002212- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2213 hex, octal, or binary; add ``append_const`` action; keep going if
2214 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2215 added ``epilog`` for better help generation).
2216
Tim Peters21fbd572006-04-21 21:18:10 +00002217- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2218 called from a thread spawned as a side effect of importing a module.
2219
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002220- The pydoc module now supports documenting packages contained in
2221 .zip or .egg files.
2222
2223- The pkgutil module now has several new utility functions, such
2224 as ``walk_packages()`` to support working with packages that are either
2225 in the filesystem or zip files.
2226
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002227- The mailbox module can now modify and delete messages from
2228 mailboxes, in addition to simply reading them. Thanks to Gregory
2229 K. Johnson for writing the code, and to the 2005 Google Summer of
2230 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002231
Tim Petersc7605f22006-04-17 21:12:33 +00002232- The ``__del__`` method of class ``local`` in module ``_threading_local``
2233 returned before accomplishing any of its intended cleanup.
2234
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002235- Patch #790710: Add breakpoint command lists in pdb.
2236

2240
Anthony Baxtere29002c2006-04-12 12:07:31 +00002241- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
2242 Windows. Bug #1469163.
2243
Phillip J. Eby47032112006-04-11 01:07:43 +00002244- The warnings, linecache, inspect, traceback, site, and doctest modules
2245 were updated to work correctly with modules imported from zipfiles or
2246 via other PEP 302 __loader__ objects.
2247
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00002248- Patch #1467770: Reduce usage of subprocess._active to processes which

2260
Martin v. Löwis4be4e652006-04-17 19:25:49 +00002261- The Makefile now has a reindent target, which runs reindent.py on
2262 the library.
2263

2269 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002270 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002271 CXX from --with-cxx-main, see description in README.
2272

2276
Tim Peters8931ff12006-05-13 23:28:20 +00002277- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2278 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2279 and "%zu" for unsigned integers of type ``size_t``.
2280
Anthony Baxter51bcb682006-04-05 14:51:42 +00002281Tests
2282-----
2283
Nick Coghlanda2268f2006-04-24 04:37:15 +00002284- test_contextlib now checks contextlib.nested can cope with exceptions
2285 being raised and caught inside exit handlers.
2286
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002287- test_cmd_line now checks operation of the -m and -c command switches
2288
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002289- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2290 it separately and by hand. It also wasn't cleaning up its changes to
2291 the current Decimal context.
2292
Thomas Woutersabd08882006-04-26 15:53:30 +00002293- regrtest.py now has a -M option to run tests that test the new limits of
2294 containers, on 64-bit architectures. Running these tests is only sensible
2295 on 64-bit machines with more than two gigabytes of memory. The argument
2296 passed is the maximum amount of memory for the tests to use.

2326 allowing it to support modules in packages and zipfiles
2327
Martin v. Löwisc661b882006-04-20 04:54:23 +00002328- On Windows, .DLL is not an accepted file name extension for
2329 extension modules anymore; extensions are only found if they
2330 end in .PYD.
2331
Martin v. Löwisea62d252006-04-03 10:56:49 +00002332- Bug #1421664: sys.stderr.encoding is now set to the same value as
2333 sys.stdout.encoding.
2334
Neal Norwitz92e212f2006-04-03 04:48:37 +00002335- __import__ accepts keyword arguments.
2336
Georg Brandlccadf842006-03-31 18:54:53 +00002337- Patch #1460496: round() now accepts keyword arguments.
2338
Anthony Baxter262c00a2006-03-30 10:53:17 +00002339- Fixed bug #1459029 - unicode reprs were double-escaped.
2340
Hye-Shik Changd478f342006-03-23 12:32:36 +00002341- Patch #1396919: The system scope threads are reenabled on FreeBSD
2342 5.4 and later versions.
2343
Neal Norwitze98ccf62006-03-23 05:39:47 +00002344- Bug #1115379: Compiling a Unicode string with an encoding declaration
2345 now gives a SyntaxError.
2346
Georg Brandlabd1ff82006-03-18 07:59:59 +00002347- Previously, Python code had no easy way to access the contents of a
2348 cell object. Now, a ``cell_contents`` attribute has been added
2349 (closes patch #1170323).
2350
Tim Peterscf79aac2006-03-16 01:14:46 +00002351- Patch #1123430: Python's small-object allocator now returns an arena to
2352 the system ``free()`` when all memory within an arena becomes unused
2353 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2354 freed. Some applications will see a drop in virtual memory size now,
2355 especially long-running applications that, from time to time, temporarily
2356 use a large number of small objects. Note that when Python returns an
2357 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002358 platform C library will in turn return that memory to the operating system.
2359 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002360 appears to be effective at least on Microsoft C and gcc-based systems.
2361 Thanks to Evan Jones for hard work and patience.
2362
Georg Brandl533ff6f2006-03-08 18:09:27 +00002363- Patch #1434038: property() now uses the getter's docstring if there is
2364 no "doc" argument given. This makes it possible to legitimately use
2365 property() as a decorator to produce a read-only property.
2366
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002367- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2368 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2369 of requiring an int or long in slicing and a few other contexts, enabling
2370 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2371
Neal Norwitz995acdf2006-03-07 05:01:00 +00002372- Fixed various bugs reported by Coverity's Prevent tool.
2373
Brett Cannonbf364092006-03-01 04:25:17 +00002374- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2375 new exception base class, BaseException, which has a new message attribute.
2376 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2377 Raising a string exception now raises a DeprecationWarning.
2378
Thomas Woutersfb609f42006-02-28 16:37:25 +00002379- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2380 explicitly relative, using 'from .module import name' to mean 'from the same
2381 package as this module is in. Imports without dots still default to the
2382 old relative-then-absolute, unless 'from __future__ import
2383 absolute_import' is used.
2384
Brett Cannona7446e32006-02-27 23:39:10 +00002385- Properly check if 'warnings' raises an exception (usually when a filter set
2386 to "error" is triggered) when raising a warning for raising string
2387 exceptions.
2388
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002389- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002390 The name was removed from Include/code.h.
2391
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002392- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002393
Guido van Rossum1968ad32006-02-25 22:38:04 +00002394- Patch 1433928:
2395 - The copy module now "copies" function objects (as atomic objects).
2396 - dict.__getitem__ now looks for a __missing__ hook before raising
2397 KeyError.
2398
Tim Peters84ef21c2006-02-28 20:39:06 +00002399- PEP 343: with statement implemented. Needs ``from __future__ import
2400 with_statement``. Use of 'with' as a variable will generate a warning.
2401 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002402 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002403 The following objects have __context__ methods:
2404 - The built-in file type.
2405 - The thread.LockType type.
2406 - The following types defined by the threading module:
2407 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2408 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002409
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002410- Fix the encodings package codec search function to only search
2411 inside its own package. Fixes problem reported in patch #1433198.
2412
2413 Note: Codec packages should implement and register their own
2414 codec search function. PEP 100 has the details.
2415
Tim Peters9ea89d22006-06-04 03:26:02 +00002416- PEP 353: Using ``Py_ssize_t`` as the index type.
2417
2418- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2419 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2420 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2421 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2422 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002423
Neal Norwitzfc76d632006-01-10 06:03:13 +00002424- Patch #1400181, fix unicode string formatting to not use the locale.
2425 This is how string objects work. u'%f' could use , instead of .
2426 for the decimal point. Now both strings and unicode always use periods.
2427
Neal Norwitz671b9e32006-01-09 07:07:12 +00002428- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2429 configure would break checking curses.h.
2430
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002431- Bug #959576: The pwd module is now builtin. This allows Python to be
2432 built on UNIX platforms without $HOME set.
2433
Neal Norwitzc10978f2005-12-19 06:07:16 +00002434- Bug #1072182, fix some potential problems if characters are signed.
2435
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002436- Bug #889500, fix line number on SyntaxWarning for global declarations.
2437
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002438- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2439
Neal Norwitze7214a12005-12-18 05:03:17 +00002440- Support for converting hex strings to floats no longer works.
2441 This was not portable. float('0x3') now raises a ValueError.
2442
Barry Warsaw2a38a862005-12-18 01:27:35 +00002443- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002444 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002445 is now displayed in interactive prompt banner.
2446
Georg Brandlfa166682005-12-17 21:45:17 +00002447- Implementation of PEP 341 - Unification of try/except and try/finally.
2448 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002449 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002450
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002451- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2452 now encodes backslash correctly.
2453
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002454- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2455
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002456- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002457 and long longs.
2458
Neal Norwitz67715f02005-11-09 06:59:35 +00002459- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002460 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002461 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002462
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002463- Replaced most Unicode charmap codecs with new ones using the
2464 new Unicode translate string feature in the builtin charmap
2465 codec; the codecs were created from the mapping tables available
2466 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2467 encodings now include a mapping for the Apple logo)
2468
Tim Peterse3547fd2005-12-16 23:13:57 +00002469- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002470
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002471- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002472
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002473- A new AST parser implementation was completed. The abstract
2474 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002475 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002476
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002477- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002478 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2479
Neal Norwitz708e51a2005-10-03 04:48:15 +00002480- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2481
Neal Norwitz11bd1192005-10-03 00:54:56 +00002482- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2483 Provide a warning when a directory is passed on the command line.
2484
Neal Norwitz40d37812005-10-02 01:48:49 +00002485- Fix segfault with invalid coding.
2486
2487- SF bug #772896: unknown encoding results in MemoryError.
2488
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002489- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002490 supported a __len__() method which evaluated to False when the iterator
2491 was empty.
2492
Guido van Rossum630db602005-09-20 18:49:54 +00002493- On 64-bit platforms, when __len__() returns a value that cannot be
2494 represented as a C int, raise OverflowError.
2495
Skip Montanarof8948ca2005-09-19 03:54:46 +00002496- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002497 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002498
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002499- SF bug #893549: parsing keyword arguments was broken with a few format
2500 codes.
2501
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002502- Changes donated by Elemental Security to make it work on AIX 5.3
2503 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2504 bug #105470: test_pwd fails on 64bit system (Opteron).
2505
Guido van Rossum539c6622005-09-14 17:49:54 +00002506- Changes donated by Elemental Security to make it work on HP-UX 11 on
2507 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2508
Georg Brandl4550b8d2005-08-26 06:43:52 +00002509- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002510 (fixes bug #1119418).
2511
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002512- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2513
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002514- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2515 exceptions that cause a function to exit.
2516
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002517- The implementation of set() and frozenset() was revised to use its
2518 own internal data structure. Memory consumption is reduced by 1/3
2519 and there are modest speed-ups as well. The API is unchanged.
2520
Tim Petersde7990b2005-07-17 23:45:23 +00002521- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2522
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002523- SF bug #1229429: PyObject_CallMethod failed to decrement some
2524 reference counts in some error exit cases.
2525
Tim Petersecc6e6a2005-07-10 22:30:55 +00002526- SF bug #1185883: Python's small-object memory allocator took over
2527 a block managed by the platform C library whenever a realloc specified
2528 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002529 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002530 portable way to copy data from the C-managed block into Python's
2531 small-object space without risking a memory fault. Python's small-object
2532 realloc now leaves such blocks under the control of the platform C
2533 realloc.
2534
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002535- SF bug #1232517: An overflow error was not detected properly when
2536 attempting to convert a large float to an int in os.utime().
2537
Raymond Hettinger3296e692005-06-29 23:29:56 +00002538- SF bug #1224347: hex longs now print with lowercase letters just
2539 like their int counterparts.
2540
Michael W. Hudson188d4362005-06-20 16:52:57 +00002541- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2542 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2543 interpreter states; back out that fix and do a better job (see
2544 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2545 for a longer write-up of the problem).
2546
Michael W. Hudsondf888462005-06-03 14:41:55 +00002547- SF patch #1180995: marshal now uses a binary format by default when
2548 serializing floats.
2549
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002550- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2551 the routines that promise to produce IEEE 754 binary representations
2552 of floats now simply copy bytes around.
2553
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002554- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2555 278.
2556
Brett Cannonc3647ac2005-04-26 03:45:26 +00002557- patch #1109424: int, long, float, complex, and unicode now check for the
2558 proper magic slot for type conversions when subclassed. Previously the
2559 magic slot was ignored during conversion. Semantics now match the way
2560 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002561 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002562 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002563 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002564
Barry Warsawc8d907c2005-04-19 23:43:40 +00002565- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2566 NULL, now raise an AttributeError when attempting to set or delete the
2567 attribute. Previously a TypeError was raised, but this was inconsistent
2568 with the equivalent pure-Python implementation.
2569
Michael W. Hudson774479c2005-04-18 08:46:17 +00002570- It is now safe to call PyGILState_Release() before
2571 PyEval_InitThreads() (note that if there is reason to believe there
2572 are multiple threads around you still must call PyEval_InitThreads()
2573 before using the Python API; this fix is for extension modules that
2574 have no way of knowing if Python is multi-threaded yet).
2575
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002576- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2577 disabled caused a crash.
2578
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002579- Bug #1165306: instancemethod_new allowed the creation of a method
2580 with im_class == im_self == NULL, which caused a crash when called.
2581
Tim Petersecc6e6a2005-07-10 22:30:55 +00002582- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002583 fixes the crash seen in bug #1165761
2584
Raymond Hettinger96229b12005-03-11 06:49:40 +00002585- Added two new builtins, any() and all().
2586
Brett Cannon409d8f22005-03-05 06:47:57 +00002587- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002588 (e.g., ``class C(): pass`` is no longer a syntax error).

2628 current thread state when the auto-GIL-state machinery knows about
2629 it (since the thread state is being deleted, continuing to remember it
2630 can't help, but can hurt if another thread happens to get created with
2631 the same thread id).

Nick Coghlan43832302006-04-23 17:04:07 +00002827- PEP 338: new module runpy defines a run_module function to support
2828 executing modules which provide access to source code or a code object
2829 via the PEP 302 import mechanisms.
2830

2839 in attribute values.
2840
Anthony Baxterc51ee692006-04-01 00:57:31 +00002841- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002842 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002843 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002844 module will not be built.
2845
Tim Petersc17976e2006-04-01 00:26:53 +00002846- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2847 aren't officially supported here, and trying to use them will probably

2869
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002870- email 4.0 package now integrated. This is largely the same as the email 3.0
2871 package that was included in Python 2.3, except that PEP 8 module names are
2872 now used (e.g. mail.message instead of email.Message). The MIME classes
2873 have been moved to a subpackage (e.g. email.mime.text instead of
2874 email.MIMEText). The old names are still supported for now. Several
2875 deprecated Message methods have been removed and lots of bugs have been
2876 fixed. More details can be found in the email package documentation.

2879 (a subclass of tuple) that provides incremental decoders and encoders
2880 (a way to use stateful codecs without the stream API). Python functions
2881 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2882 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2883 have been added.

2886 a ValueError instead of a StopIteration now (like file and cString.String do).
2887 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2888 called before (like file and StringIO.StringIO do).

2963 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2964 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2965 Ronald L. Rivest offered this advice for Python:
2966
2967 "The consensus of researchers in this area (at least as
2968 expressed at the NIST Hash Function Workshop 10/31/05),
2969 is that SHA-256 is a good choice for the time being, but
2970 that research should continue, and other alternatives may
2971 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002972

3131
Guido van Rossumd0641422005-02-03 15:01:24 +00003132- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
3133 disables recursive traversal through instance attributes, which can
3134 be exploited in various ways.
3135
Tim Peterse3547fd2005-12-16 23:13:57 +00003136- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00003137 flags on the HTTP listening socket.
3138
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00003139- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
3140 Fixed by reading the HTTP body in chunks instead of one big socket.read().
3141
Fred Drakefbdeaad2006-07-29 16:56:15 +00003142- Patches #893642, #1039083: add allow_none, encoding arguments to
3143 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.

3150
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003151- Enhancements to the csv module:
3152
3153 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003154 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003155 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003156 + Dialect parameter parsing has been re-implemented to improve error
3157 reporting.
3158 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3159 dictates.
3160 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003161 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003162 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003163 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3164 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003165 + reader now allows \r characters to be quoted (previously it only allowed
3166 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003167 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003168 + Dialect classes passed to the module are no longer instantiated by
3169 the module before being parsed (the former validation scheme required
3170 this, but the mechanism was unreliable).
3171 + The dialect registry now contains instances of the internal
3172 C-coded dialect type, rather than references to python objects.
3173 + the internal c-coded dialect type is now immutable.
3174 + register_dialect now accepts the same keyword dialect specifications
3175 as the reader and writer, allowing the user to register dialects
3176 without first creating a dialect class.
3177 + a configurable limit to the size of parsed fields has been added -
3178 previously, an unmatched quote character could result in the entire
3179 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003180 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003181 the parser field size limit (returning the former limit). The initial
3182 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003183 + A line_num attribute has been added to the reader object, which tracks
3184 the number of lines read from the source iterator. This is not
3185 the same as the number of records returned, as records can span
3186 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003187 + reader and writer objects were not being registered with the cyclic-GC.
3188 This has been fixed.
3189
Brett Cannone6539c42005-01-08 02:43:53 +00003190- _DummyThread objects in the threading module now delete self.__block that is
3191 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3192 lock primitives tend to be limited in number and thus should not be wasted on
3193 a _DummyThread object. Fixes bug #1089632.
3194
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003195- The imghdr module now detects Exif files.
3196
Raymond Hettinger6065d322004-12-20 23:51:53 +00003197- StringIO.truncate() now correctly adjusts the size attribute.
3198 (Bug #951915).
3199
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003200- locale.py now uses an updated locale alias table (built using
3201 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3202 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003203 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003204
Raymond Hettinger3557f422004-12-07 12:02:02 +00003205- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3206
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003207- the pickle module no longer accepts the deprecated None option in the
3208 args tuple returned by __reduce__().
3209
Brett Cannon84667c02004-12-07 03:25:18 +00003210- optparse now optionally imports gettext. This allows its use in setup.py.
3211
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003212- the pickle module no longer uses the deprecated bin parameter.
3213
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003214- the shelve module no longer uses the deprecated binary parameter.
3215
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003216- the pstats module no longer uses the deprecated ignore() method.
3217
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003218- the filecmp module no longer uses the deprecated use_statcache argument.
3219
Raymond Hettinger664347b2004-12-04 21:21:53 +00003220- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3221 extended or overridden by subclasses. Formerly, the subclassed method would
3222 be ignored by the rest of the module. (Bug #1078905).
3223
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003224- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003225 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003226
Walter Dörwald36733692004-12-22 12:50:50 +00003227- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3228 once when a size argument is given. This prevents a buffer overflow in the
3229 tokenizer with very long source lines.
3230
Barry Warsaw538561e2006-01-01 21:48:54 +00003231- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3232 immediately after creating the object, without any intervening
3233 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003234
Skip Montanaro05885812005-01-16 20:48:27 +00003235- The reconvert.quote function can now emit triple-quoted strings. The
3236 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003237
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003238- ``UserString.MutableString`` now supports negative indices in
3239 ``__setitem__`` and ``__delitem__``
3240
Greg Ward40407942005-03-05 02:53:17 +00003241- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3242 correctly.
3243
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003244- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3245 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3246 character even if the user has passed a size parameter to get a proper
3247 line ending. Remove the special handling of a "\r\n" that has been split
3248 between two lines.
3249
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003250- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3251 about illegal code points. The codec now supports PEP 293 style error
3252 handlers.
3253
Walter Dörwald78a78b02005-09-01 12:04:29 +00003254- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003255 from the input stream, so that the output is a byte string in the correct
3256 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003257
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003258- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3259 considering it exactly like a '*'.
3260
Walter Dörwald007f8df2005-10-09 19:42:27 +00003261- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3262 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003263
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003264- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3265
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003266- Patch #1413711: Certain patterns of differences were making difflib
3267 touch the recursion limit.
3268
Walter Dörwald58917a62006-03-31 15:26:22 +00003269- Bug #947906: An object oriented interface has been added to the calendar
3270 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003271 called as a script (e.g. via ``python -mcalendar``). Localized month and
3272 weekday names can be ouput (even if an exotic encoding is used) using
3273 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003274
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003275Build
3276-----
3277
Neal Norwitz602d3392006-03-31 08:21:40 +00003278- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3279 by using -mieee gcc option.
3280

3282
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003283- Build support for Win64-AMD64 was added.
3284
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003285- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3286
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003287- Patch #881820: look for openpty and forkpty also in libbsd.
3288
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003289- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3290 The zlib module is now builtin on Windows.
3291
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003292- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3293
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003294- Bug #1189330: configure did not correctly determine the necessary
3295 value of LINKCC if python was built with GCC 4.0.
3296
Trent Mick8321b422005-07-26 02:29:21 +00003297- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3298 vulnerability in zlib 1.2.1 and 1.2.2.
3299
Brett Cannon08cd5982005-04-24 22:26:38 +00003300- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3301 flags that change binary compatibility. Changes were also made to
3302 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003303 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003304
Bob Ippolitoed233462005-03-29 13:47:59 +00003305- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3306 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3307 no longer exists). This configure patch makes things right.
3308
Martin v. Löwise2713be2005-03-08 15:03:08 +00003309- Bug #1158607: Build with --disable-unicode again.
3310
Brett Cannon46d96232005-02-16 00:07:19 +00003311- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3312 defined. Discovered as a result of not being able to build on OS X.
3313
Brett Cannon516592f2004-12-07 00:42:59 +00003314- setup.py now uses the directories specified in LDFLAGS using the -L option
3315 and in CPPFLAGS using the -I option for adding library and include
3316 directories, respectively, for compiling extension modules against. This has
3317 led to the core being compiled using the values in CPPFLAGS. It also removes
3318 the need for the special-casing of both DarwinPorts and Fink for darwin since
3319 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3320 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3321 Fink, ``-I/opt/local/include`` for DarwinPorts).
3322
Brett Cannon43802422005-02-10 20:48:03 +00003323- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3324 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3325 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3326 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003328C API
3329-----
3330
Tim Petersc9d78aa2006-03-26 23:27:58 +00003331- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3332 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3333 is obtained via the ``PyObject_`` family, it must be released via the
3334 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3335 always been officially true, but when Python's small-object allocator was
3336 introduced, an attempt was made to cater to a few extension modules
3337 discovered at the time that obtained memory via ``PyObject_New`` but
3338 released it via ``PyMem_DEL``. It's years later, and if such code still
3339 exists it will fail now (probably with segfaults, but calling wrong
3340 low-level memory management functions can yield many symptoms).
3341
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003342- Added a C API for set and frozenset objects.
3343

3345
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003346- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3347 mapping argument now. This string is used as a mapping table. Byte values
3348 greater than the length of the string and 0xFFFE are treated as undefined
3349 mappings.
