Guido van Rossumaa975432008-04-10 22:43:58 +0000156- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
157 having a self-referential tuple, which is possible from C code. Nor did
158 object's tp_str consider that a type's tp_str could do something that could
159 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
160 respectively, fixed the issues. (Backport of r58288 from trunk.)

169 \Uxxxxxxxx did not accept values outside the Basic Multilingual Plane. This
170 affected raw unicode literals and the 'raw-unicode-escape' codec. Now
171 UTF-16 surrogates are generated in this case, like normal unicode literals
172 and the 'unicode-escape' codec.

182 less than zero will now raise a SystemError and return NULL to indicate a
183 bug in the calling C code.

1219-----------------
1220
Neal Norwitz0bcafac2006-09-11 08:51:17 +00001221- Make _PyGILState_NoteThreadState() static, it was not used anywhere
1222 outside of pystate.c and should not be necessary.
1223
Brett Cannon19d76c52006-09-09 07:18:44 +00001224- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
1225 allows calling unicode() on exceptions classes directly to succeed.
1226
Georg Brandlecab6232006-09-06 06:47:02 +00001227- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
1228 Also make sure that every exception class has __module__ set to
1229 'exceptions'.
1230
Georg Brandl37a9e572006-09-06 06:09:34 +00001231- Bug #1550983: emit better error messages for erroneous relative
1232 imports (if not in package and if beyond toplevel package).
1233
Tim Peterscbdd3502006-09-05 01:47:53 +00001234- Overflow checking code in integer division ran afoul of new gcc

1241
Neal Norwitz29a5fdb2006-09-05 02:21:38 +00001242- The return tuple from str.rpartition(sep) is (tail, sep, head) where
1243 head is the original string if sep was not found.
1244
Neal Norwitz3b3aae02006-09-05 03:56:01 +00001245- Bug #1520864: unpacking singleton tuples in list comprehensions and
1246 generator expressions (x for x, in ... ) works again. Fixing this problem
1247 required changing the .pyc magic number. This means that .pyc files
1248 generated before 2.5c2 will be regenerated.

Neal Norwitz24b6f202006-09-05 04:43:56 +00001363- Fix infinite recursion when subclassing long and overriding __hash__.
1364
1365- Fix concatenation (+=) of long strings.
1366
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001367- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001368 compared equal or unequal to a string and a UnicodeDecodeError
1369 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001370
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001371 Instead, the equal (==) and unequal (!=) comparison operators will
1372 now issue a UnicodeWarning and interpret the two objects as
1373 unequal. The UnicodeWarning can be filtered as desired using
1374 the warning framework, e.g. silenced completely, turned into an
1375 exception, logged, etc.
1376
1377 Note that compare operators other than equal and unequal will still
1378 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001379
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001380- Fix segfault when doing string formatting on subclasses of long.
1381
1382- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1383 with new-style classes.
1384
1385- Fix bug related to __len__ functions returning negative values with
1386 classic classes.
1387
1388- Patch #1538606, Fix __index__() clipping. There were some problems
1389 discovered with the API and how integers that didn't fit into Py_ssize_t
1390 were handled. This patch attempts to provide enough alternatives
1391 to effectively use __index__.
1392
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001393- Bug #1536021: __hash__ may now return long int; the final hash
1394 value is obtained by invoking hash on the long int.
1395
Thomas Hellerab1049c2006-08-08 17:37:00 +00001396- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1397
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001398- Bug #1535165: fixed a segfault in input() and raw_input() when
1399 sys.stdin is closed.
1400
Thomas Heller74d36f02006-08-04 18:17:40 +00001401- On Windows, the PyErr_Warn function is now exported from
1402 the Python dll again.
1403
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001404- Bug #1191458: tracing over for loops now produces a line event
1405 on each iteration. Fixing this problem required changing the .pyc
1406 magic number. This means that .pyc files generated before 2.5c1
1407 will be regenerated.
1408
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001409- Bug #1333982: string/number constants were inappropriately stored
1410 in the byte code and co_consts even if they were not used, ie
1411 immediately popped off the stack.
1412
Georg Brandle9462c72006-08-04 18:03:37 +00001413- Fixed a reference-counting problem in property().

1417-------
1418
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001419- Fix a bug in the ``compiler`` package that caused invalid code to be
1420 generated for generator expressions.
1421
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001422- The distutils version has been changed to 2.5.0. The change to
1423 keep it programmatically in sync with the Python version running
1424 the code (introduced in 2.5b3) has been reverted. It will continue
1425 to be maintained manually as static string literal.
1426
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001427- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001428 and this cannot be converted to the required C type, an exception is
1429 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001430 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001431
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001432- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001433 an exception.
1434
Tim Peterscbdd3502006-09-05 01:47:53 +00001435- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001436 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001437 workarounds for clocks with low resolution, to stop the code yielding
1438 duplicate UUIDs.
1439
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001440- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1441 before raising SystemExit, allowing IDLE to honor quit() and exit().
1442
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001443- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.

Georg Brandl7a1af772006-08-14 21:55:28 +00001445- Patch #1536071: trace.py should now find the full module name of a
1446 file correctly even on Windows.
1447
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001448- logging's atexit hook now runs even if the rest of the module has
1449 already been cleaned up.

1472
Thomas Heller86720042006-08-14 11:17:48 +00001473- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1474 uses the _as_parameter_ attribute when objects are passed to foreign
1475 function calls. The ctypes version number was changed to 1.0.1.
1476
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001477- Bug #1530559, struct.pack raises TypeError where it used to convert.
1478 Passing float arguments to struct.pack when integers are expected
1479 now triggers a DeprecationWarning.

1520 the documentation was changed to state that the return value
1521 is always 1 (normal) or 0 (if the specified thread wasn't found).

1530-----------------
1531
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001532- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001533 returned a long (see PEP 353).
1534
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001535- Bug #1515471: string.replace() accepts character buffers again.
1536
Neal Norwitz07aadb12006-07-30 06:55:48 +00001537- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1538 This provides the proper warning for struct.pack().
1539 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1540
Neal Norwitz0d62a062006-07-30 06:53:31 +00001541- Patch #1531113: Fix augmented assignment with yield expressions.
1542 Also fix a SystemError when trying to assign to yield expressions.
1543
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001544- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1545 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1546 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1547 excessive filesystem operations during imports.
1548
Tim Petersbc24eee2006-07-27 01:14:53 +00001549- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1550 operations on signed longs that are formally undefined by C.
1551 Unfortunately, at least one compiler now cares about that, so complicated
1552 the code to make that compiler happy again.
1553
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001554- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1555
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001556- Patch #1232023: Stop including current directory in search
1557 path on Windows.
1558
Neal Norwitze1fdb322006-07-21 05:32:28 +00001559- Fix some potential crashes found with failmalloc.
1560
Neal Norwitze7563102006-07-17 01:00:16 +00001561- Fix warnings reported by Klocwork's static analysis tool.
1562
Neal Norwitz84be93b2006-07-16 01:50:38 +00001563- Bug #1512814, Fix incorrect lineno's when code within a function
1564 had more than 255 blank lines.
1565
Georg Brandl9dceedb2006-07-12 15:31:17 +00001566- Patch #1521179: Python now accepts the standard options ``--help`` and
1567 ``--version`` as well as ``/?`` on Windows.
1568
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001569- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001570 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001571 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001572
Tim Peters112aad32006-07-19 00:03:19 +00001573- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001574 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001575 new ``sys._current_frames()`` returns a dictionary with one entry,
1576 mapping the faux "thread id" 0 to the current frame.
1577
Ronald Oussoren3075e162006-07-25 20:28:55 +00001578- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

Neal Norwitza1f10902006-07-12 07:28:29 +00001581Library
1582-------
1583
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001584- Correction of patch #1455898: In the mbcs decoder, set final=False
1585 for stream decoder, but final=True for the decode function.
1586
Georg Brandl07fec3a2006-08-01 18:49:24 +00001587- os.urandom no longer masks unrelated exceptions like SystemExit or
1588 KeyboardInterrupt.
1589
Tim Peters4643c2f2006-08-10 22:45:34 +00001590- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001591 shutil.copytree on Windows
1592
Georg Brandle34ac7c2006-07-30 11:07:23 +00001593- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1594 refers to file descriptors, not file objects.
1595
Tim Peterscbdd3502006-09-05 01:47:53 +00001596- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001597 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001598 #1513611, and probably others.
1599
Georg Brandledd9b0d2006-07-29 09:33:26 +00001600- Bug #1441397: The compiler module now recognizes module and function
1601 docstrings correctly as it did in Python 2.4.
1602
Tim Peters6f681472006-07-27 23:44:37 +00001603- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1604 lost that tests are sorted by name before being run. This rarely
1605 matters for well-written tests, but can create baffling symptoms if
1606 side effects from one test to the next affect outcomes. ``DocTestFinder``
1607 has been changed to sort the list of tests it returns.
1608
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001609- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001610 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001611
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001612- Bug #978833: Really close underlying socket in _socketobject.close.
1613
Georg Brandldb232dc2006-08-20 13:15:43 +00001614- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1615 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001616
Georg Brandlcf0c1722006-07-26 07:23:32 +00001617- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1618 to recursive calls and call it with the failing package name.
1619
Martin v. Löwis0b483032006-07-25 09:53:12 +00001620- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1621
Georg Brandlc13c34c2006-07-24 14:09:56 +00001622- Patch #1515343: Fix printing of deprecated string exceptions with a
1623 value in the traceback module.
1624
Greg Ward48fae7a2006-07-23 16:05:51 +00001625- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1626
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001627- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1628
Brett Cannoncaebe222006-07-18 04:41:36 +00001629- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1630 argument tuple. For arguments where zero is illegal, the value is forced to
1631 the minimum value that is correct. This is to support an undocumented but
1632 common way people used to fill in inconsequential information in the time
1633 tuple pre-2.4.
1634
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001635- Patch #1220874: Update the binhex module for Mach-O.
1636
Barry Warsawb110bad2006-07-21 14:51:07 +00001637- The email package has improved RFC 2231 support, specifically for
1638 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1639 (name*0=<blah>) parameter continuations. This may change the types of
1640 values returned from email.message.Message.get_param() and friends.
1641 Specifically in some cases where non-encoded continuations were used,
1642 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1643 will just return the string (since non-encoded continuations don't have
1644 charset and language parts).
1645
1646 Also, whereas % values were decoded in all parameter continuations, they are
1647 now only decoded in encoded parameter parts.
1648
Ronald Oussoren3075e162006-07-25 20:28:55 +00001649- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1650
1651- Bug #1517996: IDLE now longer shows the default Tk menu when a
1652 path browser, class browser or debugger is the frontmost window on MacOS X
1653
Barry Warsaw00decd72006-07-27 23:43:15 +00001654- Patch #1520294: Support for getset and member descriptors in types.py,
1655 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1656 of an object against these built-in types and more importantly, for getting
1657 their docstrings printed in the interactive interpreter's help() function.

1662
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001663- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1664 a socket operation on a socket with a timeout, the exception will be
1665 caught correctly. Previously, the exception was not caught.
1666
Thomas Heller1393d6a2006-07-28 21:43:20 +00001667- Patch #1529514: The _ctypes extension is now compiled on more
1668 openbsd target platforms.
1669
Tim Peters9cab5932006-07-28 00:30:00 +00001670- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1671 a memory leak, affecting pickles and deep copies.
1672
Tim Petersbc24eee2006-07-27 01:14:53 +00001673- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1675
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001676- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1677
Thomas Hellerce049a02006-07-14 17:51:14 +00001678- Patch #1521817: Index range checking on ctypes arrays containing
1679 exactly one element enabled again. This allows iterating over these
1680 arrays, without the need to check the array size before.
1681
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001682- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001683 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001684 /dev/null in certain cases; this is now fixed.
1685
Thomas Heller47d7a062006-07-12 08:43:47 +00001686- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1687 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001688
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001689- Because of a misspelled preprocessor symbol, ctypes was always
1690 compiled without thread support; this is now fixed.
1691
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001692- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1693 methods now allow their database parameter to be None as the
1694 sleepycat API allows.
1695
Matt Flemingec926502006-07-28 11:27:27 +00001696- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1697 bluetooth API compared with Linux and FreeBSD.

1702- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1703 how long the test file should take to play. Now accepts taking 2.93 secs
1704 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1705
Georg Brandl4793aa32006-07-28 18:31:39 +00001706- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1707 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1708 run via ``regrtest.py``. Now they do.

1718- PythonLauncher now works correctly when the path to the script contains
1719 characters that are treated specially by the shell (such as quotes).
1720
1721- Bug #1527397: PythonLauncher now launches scripts with the working directory
1722 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001723 directory. That latter was an implementation accident and not what users

Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001735- Bug #1441486: The literal representation of -(sys.maxint - 1)
1736 again evaluates to a int object, not a long.
1737
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001738- Bug #1501934: The scope of global variables that are locally assigned
1739 using augmented assignment is now correctly determined.
1740
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001741- Bug #927248: Recursive method-wrapper objects can now safely
1742 be released.
1743
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001744- Bug #1417699: Reject locale-specific decimal point in float()
1745 and atof().
1746
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001747- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1748 omit a default "error" argument for NULL pointer. This allows
1749 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001750
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001751- Bug #1519018: 'as' is now validated properly in import statements.
1752
Neal Norwitz28746ab2006-07-09 22:14:42 +00001753- On 64 bit systems, int literals that use less than 64 bits are
1754 now ints rather than longs.
1755
Neal Norwitzed657552006-07-10 00:04:44 +00001756- Bug #1512814, Fix incorrect lineno's when code at module scope
1757 started after line 256.
1758
Tim Peters32a83612006-07-10 21:08:24 +00001759- New function ``sys._current_frames()`` returns a dict mapping thread
1760 id to topmost thread stack frame. This is for expert use, and is
1761 especially useful for debugging application deadlocks. The functionality
1762 was previously available in Fazal Majid's ``threadframe`` extension
1763 module, but it wasn't possible to do this in a wholly threadsafe way from
1764 an extension.

1770 VS 2003.
1771
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001772- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1773
Tim Peters32a83612006-07-10 21:08:24 +00001774- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001775 environment variable to be set in order to the SDK environment
1776 for finding the compiler, include files, etc.

1779
Nick Coghlan2d792252006-07-06 13:47:18 +00001780- warnings.py now ignores ImportWarning by default
1781
Thomas Woutersadd19112006-07-05 11:03:49 +00001782- string.Template() now correctly handles tuple-values. Previously,
1783 multi-value tuples would raise an exception and single-value tuples would
1784 be treated as the value they contain, instead.
1785
Martin v. Löwisede77f52006-07-03 13:01:35 +00001786- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1793 degrees and radians.
1794
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001795- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001796 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001797
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001798- Bug #1514703: Only setup canvas window in turtle when the canvas
1799 is created.
1800
Martin v. Löwis7596e832006-07-01 15:33:37 +00001801- Bug #1513223: .close() of a _socketobj now releases the underlying
1802 socket again, which then gets closed as it becomes unreferenced.
1803
Fred Drake10497c82006-06-29 02:57:48 +00001804- Bug #1504333: Make sgmllib support angle brackets in quoted
1805 attribute values.
1806
1807- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1808 sgmllib ('[' and ']' were not accepted).
1809
Georg Brandl1be63af2006-06-28 20:23:25 +00001810- Fix a bug in the turtle module's end_fill function.
1811
Brett Cannon53ab5b72006-06-22 16:49:14 +00001812- Bug #1510580: The 'warnings' module improperly required that a Warning
1813 category be either a types.ClassType and a subclass of Warning. The proper
1814 check is just that it is a subclass with Warning as the documentation states.
1815
Georg Brandlad29e632006-06-21 17:45:17 +00001816- The compiler module now correctly compiles the new try-except-finally
1817 statement (bug #1509132).
1818
Neal Norwitz60373cd2006-06-22 06:30:50 +00001819- The wsgiref package is now installed properly on Unix.
1820
Vinay Sajip28e57612006-07-01 10:45:20 +00001821- A bug was fixed in logging.config.fileConfig() which caused a crash on
1822 shutdown when fileConfig() was called multiple times.
1823
Gerhard Häring762fbd32006-07-02 17:48:30 +00001824- The sqlite3 module did cut off data from the SQLite database at the first
1825 null character before sending it to a custom converter. This has been fixed
1826 now.

1829-----------------
1830
Tim Peters112aad32006-07-19 00:03:19 +00001831- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1832 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1833 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001834
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001835- Assigning None to pointer type fields in ctypes structures possible
1836 overwrote the wrong fields, this is fixed now.
1837
1838- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1839 on non-Windows platforms.
1840
1841- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1842 integer or long, without range checking.
1843
1844- Patch #1517790: It is now possible to use custom objects in the ctypes
1845 foreign function argtypes sequence as long as they provide a from_param
1846 method, no longer is it required that the object is a ctypes type.
1847
1848- The '_ctypes' extension module now works when Python is configured
1849 with the --without-threads option.
1850
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001851- Bug #1513646: os.access on Windows now correctly determines write
1852 access, again.
1853
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001854- Bug #1512695: cPickle.loads could crash if it was interrupted with
1855 a KeyboardInterrupt.
1856
Neal Norwitza12aa882006-07-06 06:45:08 +00001857- Bug #1296433: parsing XML with a non-default encoding and
1858 a CharacterDataHandler could crash the interpreter in pyexpat.
1859
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001860- Patch #1516912: improve Modules support for OpenVMS.

1863-----
1864
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001865- Automate Windows build process for the Win64 SSL module.
1866
Tim Peters32a83612006-07-10 21:08:24 +00001867- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001868 Previously, the slight difference could cause compilation errors of the
1869 'zlib' module on systems with more than one version of zlib.
1870
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001871- The MSI compileall step was fixed to also support a TARGETDIR
1872 with spaces in it.
1873
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001874- Bug #1517388: sqlite3.dll is now installed on Windows independent
1875 of Tcl/Tk.
1876
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001877- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001878 trying to be installed even though it's empty.

Anthony Baxter51bcb682006-04-05 14:51:42 +00001899
Anthony Baxterd1136802006-06-19 12:04:15 +00001900*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +00001901
1902Core and builtins
1903-----------------
1904
Georg Brandla56b9152006-06-19 06:35:54 +00001905- Patch #1507676: Error messages returned by invalid abstract object operations
1906 (such as iterating over an integer) have been improved and now include the
1907 type of the offending object to help with debugging.
1908
Brett Cannonea3912b2006-06-13 21:46:41 +00001909- Bug #992017: A classic class that defined a __coerce__() method that returned
1910 its arguments swapped would infinitely recurse and segfault the interpreter.
1911
Neal Norwitz909eb122006-06-12 02:13:21 +00001912- Fix the socket tests so they can be run concurrently.
1913
Neal Norwitzb9845e72006-06-12 02:11:18 +00001914- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001915 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001916
Brett Cannon22565aa2006-06-09 22:31:23 +00001917- Bug #532646: object.__call__() will continue looking for the __call__
1918 attribute on objects until one without one is found. This leads to recursion
1919 when you take a class and set its __call__ attribute to an instance of the
1920 class. Originally fixed for classic classes, but this fix is for new-style.
1921 Removes the infinite_rec_3 crasher.
1922
Georg Brandl24250812006-06-09 18:45:48 +00001923- The string and unicode methods startswith() and endswith() now accept
1924 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1925
Brett Cannonde3b0522006-06-08 17:00:45 +00001926- Buffer objects, at the C level, never used the char buffer
1927 implementation even when the char buffer for the wrapped object was
1928 explicitly requested (originally returned the read or write buffer).
1929 Now a TypeError is raised if the char buffer is not present but is
1930 requested.
1931
Georg Brandlddbaa662006-06-04 21:56:52 +00001932- Patch #1346214: Statements like "if 0: suite" are now again optimized
1933 away like they were in Python 2.4.
1934
Georg Brandlb7c8f542006-05-27 12:30:25 +00001935- Builtin exceptions are now full-blown new-style classes instead of
1936 instances pretending to be classes, which speeds up exception handling
1937 by about 80% in comparison to 2.5a2.
1938
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001939- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1940 Unicode 4.1.
1941
Georg Brandlf4ef1162006-05-26 18:03:31 +00001942- Patch #921466: sys.path_importer_cache is now used to cache valid and
1943 invalid file paths for the built-in import machinery which leads to
1944 fewer open calls on startup.
1945
Tim Peters696cf432006-05-24 21:10:40 +00001946- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1947 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1948 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1949 the number of input digits (it was and remains linear-time for bases
1950 2, 4, 8, 16 and 32).
1951
Tim Petersb713ec22006-05-23 18:45:30 +00001952- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1953 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1954 an integer close to ``sys.maxint``. This was repaired by patch
1955 #1335972, which also gives a nice speedup.
1956
Richard Jonescebbefc2006-05-23 18:28:17 +00001957- Patch #1337051: reduced size of frame objects.
1958
1959- PyErr_NewException now accepts a tuple of base classes as its
1960 "base" parameter.
1961
Richard Jones7c88dcc2006-05-23 10:37:38 +00001962- Patch #876206: function call speedup by retaining allocated frame
1963 objects.
1964
Georg Brandl7b90e162006-05-18 07:01:27 +00001965- Bug #1462152: file() now checks more thoroughly for invalid mode
1966 strings and removes a possible "U" before passing the mode to the
1967 C library function.
1968
Neal Norwitz1004a532006-05-15 07:17:23 +00001969- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1970
Neal Norwitz373f0a72006-05-15 07:04:36 +00001971- Bug #1487966: Fix SystemError with conditional expression in assignment
1972
Martin v. Löwis879768d2006-05-11 13:28:43 +00001973- WindowsError now has two error code attributes: errno, which carries
1974 the error values from errno.h, and winerror, which carries the error
1975 values from winerror.h. Previous versions put the winerror.h values
1976 (from GetLastError()) into the errno attribute.
1977
Martin v. Löwis77736712006-05-04 05:51:03 +00001978- Patch #1475845: Raise IndentationError for unexpected indent.
1979
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001980- Patch #1479181: split open() and file() from being aliases for each other.
1981
Tim Peters44bd9862006-06-01 13:49:23 +00001982- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1983 methods were always silently ignored by dictionaries when comparing keys.
1984 They are now passed through (except when using the C API function
1985 ``PyDict_GetItem()``, whose semantics did not change).
1986
1987- Bug #1456209: In some obscure cases it was possible for a class with a
1988 custom ``__eq__()`` method to confuse dict internals when class instances
1989 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1990 No, you don't have any code that did this ;-)

1998
Brett Cannon6ee7d012006-06-08 16:23:04 +00001999- Change binascii.hexlify to accept a read-only buffer instead of only a char
2000 buffer and actually follow its documentation.
2001
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00002002- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
2003
Nick Coghlanc649ec52006-05-29 12:43:05 +00002004- Patch #1478788 (modified version): The functional extension module has
2005 been renamed to _functools and a functools Python wrapper module added.
2006 This provides a home for additional function related utilities that are
2007 not specifically about functional programming. See PEP 309.
2008
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00002009- Patch #1493701: performance enhancements for struct module.

Georg Brandl8d3342b2006-05-16 07:38:27 +00002013- Patch #1435422: zlib's compress and decompress objects now have a
2014 copy() method.
2015
Andrew MacIntyre92913322006-06-13 15:04:24 +00002016- Patch #1454481: thread stack size is now tunable at runtime for thread
2017 enabled builds on Windows and systems with Posix threads support.
2018
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002019- On Win32, os.listdir now supports arbitrarily-long Unicode path names
2020 (up to the system limit of 32K characters).
2021
2022- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
2023 As a result, these functions now raise WindowsError instead of OSError.
2024
Tim Peters7a822da2006-05-25 21:50:17 +00002025- ``time.clock()`` on Win64 should use the high-performance Windows
2026 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
2027 Windows platforms).
2028
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002029- Calling Tk_Init twice is refused if the first call failed as that
2030 may deadlock.
2031
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00002032- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
2033 accept it without potentially using an uninitialized pointer.
2034
2035- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
2036 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

2041
Gregory P. Smith372b5832006-06-05 18:48:21 +00002042- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
2043 parameter is supplied. [SF pybsddb bug #1477863]
2044
Gregory P. Smith3c228b12006-06-05 23:59:37 +00002045- bsddb: the __len__ method of a DB object has been fixed to return correct
2046 results. It could previously incorrectly return 0 in some cases.
2047 Fixes SF bug 1493322 (pybsddb bug 1184012).
2048
Gregory P. Smithff7d9912006-06-08 05:17:08 +00002049- bsddb: the bsddb.dbtables Modify method now raises the proper error and
2050 aborts the db transaction safely when a modifier callback fails.
2051 Fixes SF python patch/bug #1408584.
2052
Gregory P. Smith506f7b52006-06-15 08:52:32 +00002053- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00002054 now works reliably. It has been updated to use automatic BerkeleyDB

2087
Tim Peters43898b42006-06-14 04:09:25 +00002088- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
2089 guarantee that adjacent triples in the return list always describe
2090 non-adjacent blocks. Previously, a pair of matching blocks could end
2091 up being described by multiple adjacent triples that formed a partition
2092 of the matching pair.

2101
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00002102- The wsgiref package has been added to the standard library.
2103
Nick Coghlan676725d2006-06-08 13:54:49 +00002104- The functions update_wrapper() and wraps() have been added to the functools
2105 module. These make it easier to copy relevant metadata from the original
2106 function when writing wrapper functions.
2107
Tim Petersd6a9eef2006-06-05 01:48:21 +00002108- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
2109 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00002110
Martin v. Löwis3f767792006-06-04 19:36:28 +00002111- Patch #1359618: Speed up charmap encoder by using a trie structure
2112 for lookup.
2113
Tim Petersd609b1a2006-06-02 23:22:51 +00002114- The functions in the ``pprint`` module now sort dictionaries by key
2115 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
2116 if and only if its display required more than one line, although that
2117 wasn't documented. The new behavior increases predictability; e.g.,
2118 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.

Georg Brandlb89316f2006-05-17 15:51:16 +00002130- Patch #1180296: Two new functions were added to the locale module:
2131 format_string() to get the effect of "format % items" but locale-aware,
2132 and currency() to format a monetary number with currency sign.

2141 stdout arguments, making it possible to redirect input and output
2142 for remote debugging.
2143
2144- Patch #1484695: Update the tarfile module to version 0.8. This fixes
2145 a couple of issues, notably handling of long file names using the
2146 GNU LONGNAME extension.
2147
2148- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
2149 new flag when ``name`` is already the name of an option flag.
2150
2151- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
2152 package.
2153
2154- Patch #1472854: make the rlcompleter.Completer class usable on non-
2155 UNIX platforms.

2195Core and builtins
2196-----------------
2197
Thomas Heller1b046642006-04-18 18:51:06 +00002198- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2199 by converting these apis from macros into exported functions again:
2200
2201 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2202 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2203 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
2204 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
2205 PyRun_String Py_CompileString
2206
Martin v. Löwis45294a92006-04-18 06:24:08 +00002207- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2208
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002209- All uses of PyStructSequence_InitType have been changed to initialize
2210 the type objects only once, even if the interpreter is initialized
2211 multiple times.
2212
Neal Norwitz61546162006-04-14 05:20:28 +00002213- Bug #1454485, array.array('u') could crash the interpreter. This was
2214 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2215 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2216
2217- Py_UNICODE is unsigned. It was always documented as unsigned, but
2218 due to a bug had a signed value in previous versions.
2219
Tim Peters3a5e8b12006-04-11 01:44:07 +00002220- Patch #837242: ``id()`` of any Python object always gives a positive
2221 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2222 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002223 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002224 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002225
Tim Peters3a5e8b12006-04-11 01:44:07 +00002226 def __hash__(self):
2227 return id(self) # WRONG
2228
2229 because a hash result must be a (short) Python int but it was always
2230 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002231 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002232 was always usable as a hash value before this patch. That's no longer
2233 necessarily so.
2234
2235- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002236 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002237 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002238 #1454844)
2239
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002240- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2241 involving generators that have paused outside of any ``try`` or ``with``
2242 blocks. (In 2.5a1, a paused generator that was part of a reference
2243 cycle could not be garbage collected, regardless of whether it was
2244 paused in a ``try`` or ``with`` block.)

Tim Peters711bf302006-04-25 03:31:36 +00002276- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2277 a doctest to be skipped (the code is not run, and the expected output
2278 or exception is ignored).
2279
Nick Coghlanda2268f2006-04-24 04:37:15 +00002280- Fixed contextlib.nested to cope with exceptions being raised and
2281 caught inside exit handlers.
2282
Greg Wardab05edc2006-04-23 03:47:58 +00002283- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2284 hex, octal, or binary; add ``append_const`` action; keep going if
2285 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2286 added ``epilog`` for better help generation).
2287
Tim Peters21fbd572006-04-21 21:18:10 +00002288- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2289 called from a thread spawned as a side effect of importing a module.
2290
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002291- The pydoc module now supports documenting packages contained in
2292 .zip or .egg files.
2293
2294- The pkgutil module now has several new utility functions, such
2295 as ``walk_packages()`` to support working with packages that are either
2296 in the filesystem or zip files.
2297
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002298- The mailbox module can now modify and delete messages from
2299 mailboxes, in addition to simply reading them. Thanks to Gregory
2300 K. Johnson for writing the code, and to the 2005 Google Summer of
2301 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002302
Tim Petersc7605f22006-04-17 21:12:33 +00002303- The ``__del__`` method of class ``local`` in module ``_threading_local``
2304 returned before accomplishing any of its intended cleanup.
2305
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002306- Patch #790710: Add breakpoint command lists in pdb.

Martin v. Löwisc90b17e2006-04-15 08:13:05 +00002337- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002338
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002339- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2340 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002341 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002342 CXX from --with-cxx-main, see description in README.
2343
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002344- Patch #1429775: Link extension modules with the shared libpython.
2345
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002346- Fixed a libffi build problem on MIPS systems.
2347
Tim Peters8931ff12006-05-13 23:28:20 +00002348- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2349 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2350 and "%zu" for unsigned integers of type ``size_t``.

Anthony Baxter51bcb682006-04-05 14:51:42 +00002352Tests
2353-----
2354
Nick Coghlanda2268f2006-04-24 04:37:15 +00002355- test_contextlib now checks contextlib.nested can cope with exceptions
2356 being raised and caught inside exit handlers.
2357
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002358- test_cmd_line now checks operation of the -m and -c command switches
2359
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002360- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2361 it separately and by hand. It also wasn't cleaning up its changes to
2362 the current Decimal context.
2363
Thomas Woutersabd08882006-04-26 15:53:30 +00002364- regrtest.py now has a -M option to run tests that test the new limits of
2365 containers, on 64-bit architectures. Running these tests is only sensible
2366 on 64-bit machines with more than two gigabytes of memory. The argument
2367 passed is the maximum amount of memory for the tests to use.
2368
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00002369Tools

2371
2372- Added the Python benchmark suite pybench to the Tools/ directory;
2373 contributed by Marc-Andre Lemburg.

Anthony Baxter51bcb682006-04-05 14:51:42 +00002375Documentation
2376-------------
2377
Tim Petersb06d28c2006-05-12 01:57:59 +00002378- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2379
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002380- PEP 343: Added Context Types section to the library reference
2381 and attempted to bring other PEP 343 related documentation into
2382 line with the implementation and/or python-dev discussions.
2383
Tim Peters8dc73d22006-04-24 02:03:16 +00002384- Bug #1337990: clarified that ``doctest`` does not support examples
2385 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002388What's New in Python 2.5 alpha 1?
2389=================================
2390
Anthony Baxterebed3f62006-04-03 15:03:44 +00002391*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002392
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002393Core and builtins
2394-----------------
2395
Nick Coghlan43832302006-04-23 17:04:07 +00002396- PEP 338: -m command line switch now delegates to runpy.run_module
2397 allowing it to support modules in packages and zipfiles
2398
Martin v. Löwisc661b882006-04-20 04:54:23 +00002399- On Windows, .DLL is not an accepted file name extension for
2400 extension modules anymore; extensions are only found if they
2401 end in .PYD.
2402
Martin v. Löwisea62d252006-04-03 10:56:49 +00002403- Bug #1421664: sys.stderr.encoding is now set to the same value as
2404 sys.stdout.encoding.
2405
Neal Norwitz92e212f2006-04-03 04:48:37 +00002406- __import__ accepts keyword arguments.
2407
Georg Brandlccadf842006-03-31 18:54:53 +00002408- Patch #1460496: round() now accepts keyword arguments.
2409
Anthony Baxter262c00a2006-03-30 10:53:17 +00002410- Fixed bug #1459029 - unicode reprs were double-escaped.
2411
Hye-Shik Changd478f342006-03-23 12:32:36 +00002412- Patch #1396919: The system scope threads are reenabled on FreeBSD
2413 5.4 and later versions.
2414
Neal Norwitze98ccf62006-03-23 05:39:47 +00002415- Bug #1115379: Compiling a Unicode string with an encoding declaration
2416 now gives a SyntaxError.
2417
Georg Brandlabd1ff82006-03-18 07:59:59 +00002418- Previously, Python code had no easy way to access the contents of a
2419 cell object. Now, a ``cell_contents`` attribute has been added
2420 (closes patch #1170323).
2421
Tim Peterscf79aac2006-03-16 01:14:46 +00002422- Patch #1123430: Python's small-object allocator now returns an arena to
2423 the system ``free()`` when all memory within an arena becomes unused
2424 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2425 freed. Some applications will see a drop in virtual memory size now,
2426 especially long-running applications that, from time to time, temporarily
2427 use a large number of small objects. Note that when Python returns an
2428 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002429 platform C library will in turn return that memory to the operating system.
2430 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002431 appears to be effective at least on Microsoft C and gcc-based systems.
2432 Thanks to Evan Jones for hard work and patience.
2433
Georg Brandl533ff6f2006-03-08 18:09:27 +00002434- Patch #1434038: property() now uses the getter's docstring if there is
2435 no "doc" argument given. This makes it possible to legitimately use
2436 property() as a decorator to produce a read-only property.
2437
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002438- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2439 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2440 of requiring an int or long in slicing and a few other contexts, enabling
2441 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2442
Neal Norwitz995acdf2006-03-07 05:01:00 +00002443- Fixed various bugs reported by Coverity's Prevent tool.
2444
Brett Cannonbf364092006-03-01 04:25:17 +00002445- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2446 new exception base class, BaseException, which has a new message attribute.
2447 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2448 Raising a string exception now raises a DeprecationWarning.
2449
Thomas Woutersfb609f42006-02-28 16:37:25 +00002450- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2451 explicitly relative, using 'from .module import name' to mean 'from the same
2452 package as this module is in. Imports without dots still default to the
2453 old relative-then-absolute, unless 'from __future__ import
2454 absolute_import' is used.
2455
Brett Cannona7446e32006-02-27 23:39:10 +00002456- Properly check if 'warnings' raises an exception (usually when a filter set
2457 to "error" is triggered) when raising a warning for raising string
2458 exceptions.
2459
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002460- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002461 The name was removed from Include/code.h.
2462
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002463- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002464
Guido van Rossum1968ad32006-02-25 22:38:04 +00002465- Patch 1433928:
2466 - The copy module now "copies" function objects (as atomic objects).
2467 - dict.__getitem__ now looks for a __missing__ hook before raising
2468 KeyError.
2469
Tim Peters84ef21c2006-02-28 20:39:06 +00002470- PEP 343: with statement implemented. Needs ``from __future__ import
2471 with_statement``. Use of 'with' as a variable will generate a warning.
2472 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002473 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002474 The following objects have __context__ methods:
2475 - The built-in file type.
2476 - The thread.LockType type.
2477 - The following types defined by the threading module:
2478 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2479 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002480
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002481- Fix the encodings package codec search function to only search
2482 inside its own package. Fixes problem reported in patch #1433198.
2483
2484 Note: Codec packages should implement and register their own
2485 codec search function. PEP 100 has the details.
2486
Tim Peters9ea89d22006-06-04 03:26:02 +00002487- PEP 353: Using ``Py_ssize_t`` as the index type.
2488
2489- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2490 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2491 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2492 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2493 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002494
Neal Norwitzfc76d632006-01-10 06:03:13 +00002495- Patch #1400181, fix unicode string formatting to not use the locale.
2496 This is how string objects work. u'%f' could use , instead of .
2497 for the decimal point. Now both strings and unicode always use periods.
2498
Neal Norwitz671b9e32006-01-09 07:07:12 +00002499- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2500 configure would break checking curses.h.
2501
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002502- Bug #959576: The pwd module is now builtin. This allows Python to be
2503 built on UNIX platforms without $HOME set.
2504
Neal Norwitzc10978f2005-12-19 06:07:16 +00002505- Bug #1072182, fix some potential problems if characters are signed.
2506
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002507- Bug #889500, fix line number on SyntaxWarning for global declarations.
2508
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002509- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2510
Neal Norwitze7214a12005-12-18 05:03:17 +00002511- Support for converting hex strings to floats no longer works.
2512 This was not portable. float('0x3') now raises a ValueError.
2513
Barry Warsaw2a38a862005-12-18 01:27:35 +00002514- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002515 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002516 is now displayed in interactive prompt banner.
2517
Georg Brandlfa166682005-12-17 21:45:17 +00002518- Implementation of PEP 341 - Unification of try/except and try/finally.
2519 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002520 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002521
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002522- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2523 now encodes backslash correctly.
2524
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002525- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2526
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002527- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002528 and long longs.
2529
Neal Norwitz67715f02005-11-09 06:59:35 +00002530- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002531 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002532 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002533
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002534- Replaced most Unicode charmap codecs with new ones using the
2535 new Unicode translate string feature in the builtin charmap
2536 codec; the codecs were created from the mapping tables available
2537 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2538 encodings now include a mapping for the Apple logo)
2539
Tim Peterse3547fd2005-12-16 23:13:57 +00002540- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002541
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002542- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002543
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002544- A new AST parser implementation was completed. The abstract
2545 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002546 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002547
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002548- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002549 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2550
Neal Norwitz708e51a2005-10-03 04:48:15 +00002551- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2552
Neal Norwitz11bd1192005-10-03 00:54:56 +00002553- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2554 Provide a warning when a directory is passed on the command line.
2555
Neal Norwitz40d37812005-10-02 01:48:49 +00002556- Fix segfault with invalid coding.
2557
2558- SF bug #772896: unknown encoding results in MemoryError.
2559
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002560- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002561 supported a __len__() method which evaluated to False when the iterator
2562 was empty.
2563
Guido van Rossum630db602005-09-20 18:49:54 +00002564- On 64-bit platforms, when __len__() returns a value that cannot be
2565 represented as a C int, raise OverflowError.
2566
Skip Montanarof8948ca2005-09-19 03:54:46 +00002567- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002568 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002569
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002570- SF bug #893549: parsing keyword arguments was broken with a few format
2571 codes.
2572
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002573- Changes donated by Elemental Security to make it work on AIX 5.3
2574 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2575 bug #105470: test_pwd fails on 64bit system (Opteron).
2576
Guido van Rossum539c6622005-09-14 17:49:54 +00002577- Changes donated by Elemental Security to make it work on HP-UX 11 on
2578 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2579
Georg Brandl4550b8d2005-08-26 06:43:52 +00002580- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002581 (fixes bug #1119418).
2582
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002583- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2584
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002585- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2586 exceptions that cause a function to exit.
2587
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002588- The implementation of set() and frozenset() was revised to use its
2589 own internal data structure. Memory consumption is reduced by 1/3
2590 and there are modest speed-ups as well. The API is unchanged.
2591
Tim Petersde7990b2005-07-17 23:45:23 +00002592- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2593
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002594- SF bug #1229429: PyObject_CallMethod failed to decrement some
2595 reference counts in some error exit cases.
2596
Tim Petersecc6e6a2005-07-10 22:30:55 +00002597- SF bug #1185883: Python's small-object memory allocator took over
2598 a block managed by the platform C library whenever a realloc specified
2599 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002600 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002601 portable way to copy data from the C-managed block into Python's
2602 small-object space without risking a memory fault. Python's small-object
2603 realloc now leaves such blocks under the control of the platform C
2604 realloc.
2605
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002606- SF bug #1232517: An overflow error was not detected properly when
2607 attempting to convert a large float to an int in os.utime().
2608
Raymond Hettinger3296e692005-06-29 23:29:56 +00002609- SF bug #1224347: hex longs now print with lowercase letters just
2610 like their int counterparts.
2611
Michael W. Hudson188d4362005-06-20 16:52:57 +00002612- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2613 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2614 interpreter states; back out that fix and do a better job (see
2615 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2616 for a longer write-up of the problem).
2617
Michael W. Hudsondf888462005-06-03 14:41:55 +00002618- SF patch #1180995: marshal now uses a binary format by default when
2619 serializing floats.
2620
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002621- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2622 the routines that promise to produce IEEE 754 binary representations
2623 of floats now simply copy bytes around.
2624
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002625- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2626 278.
2627
Brett Cannonc3647ac2005-04-26 03:45:26 +00002628- patch #1109424: int, long, float, complex, and unicode now check for the
2629 proper magic slot for type conversions when subclassed. Previously the
2630 magic slot was ignored during conversion. Semantics now match the way
2631 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002632 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002633 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002634 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002635
Barry Warsawc8d907c2005-04-19 23:43:40 +00002636- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2637 NULL, now raise an AttributeError when attempting to set or delete the
2638 attribute. Previously a TypeError was raised, but this was inconsistent
2639 with the equivalent pure-Python implementation.
2640
Michael W. Hudson774479c2005-04-18 08:46:17 +00002641- It is now safe to call PyGILState_Release() before
2642 PyEval_InitThreads() (note that if there is reason to believe there
2643 are multiple threads around you still must call PyEval_InitThreads()
2644 before using the Python API; this fix is for extension modules that
2645 have no way of knowing if Python is multi-threaded yet).
2646
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002647- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2648 disabled caused a crash.
2649
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002650- Bug #1165306: instancemethod_new allowed the creation of a method
2651 with im_class == im_self == NULL, which caused a crash when called.
2652
Tim Petersecc6e6a2005-07-10 22:30:55 +00002653- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002654 fixes the crash seen in bug #1165761
2655
Raymond Hettinger96229b12005-03-11 06:49:40 +00002656- Added two new builtins, any() and all().
2657
Brett Cannon409d8f22005-03-05 06:47:57 +00002658- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002659 (e.g., ``class C(): pass`` is no longer a syntax error).
2660 Patch #1176012 added support to the 'parser' module and 'compiler' package
2661 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002662
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002663- Patch #1115086: Support PY_LONGLONG in structmember.
2664
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002665- Bug #1155938: new style classes did not check that __init__() was
2666 returning None.
2667
Tim Petersecc6e6a2005-07-10 22:30:55 +00002668- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002669 ('\') with a specific error message.
2670
Martin v. Löwisff232d72005-03-03 09:24:38 +00002671- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2672
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002673- Bug #1124295: the __name__ attribute of file objects was
2674 inadvertently made inaccessible in restricted mode.
2675
Tim Petersecc6e6a2005-07-10 22:30:55 +00002676- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002677 an ferror() call.
2678
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002679- min() and max() now support key= arguments with the same meaning as in
2680 list.sort().
2681
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002682- The peephole optimizer now performs simple constant folding in expressions:
2683 (2+3) --> (5).
2684
Raymond Hettingera422c342005-01-11 03:03:27 +00002685- set and frozenset objects can now be marshalled. SF #1098985.
2686
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002687- Bug #1077106: Poor argument checking could cause memory corruption
2688 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002689
Jeremy Hyltonab630502005-02-04 18:44:06 +00002690- The parser did not complain about future statements in illegal
2691 positions. It once again reports a syntax error if a future
2692 statement occurs after anything other than a doc string.
2693
Neil Schemenauercf52c072005-08-12 17:34:58 +00002694- Change the %s format specifier for str objects so that it returns a
2695 unicode instance if the argument is not an instance of basestring and
2696 calling __str__ on the argument returns a unicode instance.
2697
Tim Petersf4e69282006-02-27 17:15:31 +00002698- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2699 current thread state when the auto-GIL-state machinery knows about
2700 it (since the thread state is being deleted, continuing to remember it
2701 can't help, but can hurt if another thread happens to get created with
2702 the same thread id).
2703
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002704Extension Modules

2721
2722- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2723
2724- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002725 is deprecated. The undocumented re.engine variable no longer exists.

2729
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002730- The unicodedata module was updated to the 4.1 version of the Unicode
2731 database. The 3.2 version is still available as unicodedata.db_3_2_0
2732 for applications that require this specific version (such as IDNA).
2733
Neal Norwitzb62c4332006-03-04 18:35:47 +00002734- The timing module is no longer built by default. It was deprecated
2735 in PEP 4 in Python 2.0 or earlier.
2736
Guido van Rossum1968ad32006-02-25 22:38:04 +00002737- Patch 1433928: Added a new type, defaultdict, to the collections module.

2739
Georg Brandldbd83392006-02-20 09:42:33 +00002740- Bug #854823: socketmodule now builds on Sun platforms even when

2755
Martin v. Löwis14694662006-02-03 12:54:16 +00002756- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2757 are reported, the limit on path name lengths is removed, and stat reports
2758 WindowsError now (instead of OSError).
2759

2835 the request code argument, which results in more C-like behaviour
2836 for large or negative values.
2837
Tim Petersecc6e6a2005-07-10 22:30:55 +00002838- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

2880
Raymond Hettingerb2594052004-12-05 09:25:51 +00002881- itertools.islice() now accepts None for the start and step arguments.

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002894- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2895 been renamed to have only a single underscore prefix. This was done to
2896 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002897
Nick Coghlan43832302006-04-23 17:04:07 +00002898- PEP 338: new module runpy defines a run_module function to support
2899 executing modules which provide access to source code or a code object
2900 via the PEP 302 import mechanisms.
2901
Anthony Baxter93f5b932006-04-03 08:05:07 +00002902- The email module's parsedate_tz function now sets the daylight savings

2910 in attribute values.
2911
Anthony Baxterc51ee692006-04-01 00:57:31 +00002912- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002913 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002914 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002915 module will not be built.
2916
Tim Petersc17976e2006-04-01 00:26:53 +00002917- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2918 aren't officially supported here, and trying to use them will probably
2919 raise an exception some day. But dicts have been allowed, and "mostly
2920 worked", so support for them won't go away without warning.
2921
Georg Brandl338ef7d2006-03-31 18:42:16 +00002922- Bug #1445068: getpass.getpass() can now be given an explicit stream
2923 argument to specify where to write the prompt.
2924
Georg Brandl22ec80b2006-03-31 18:25:44 +00002925- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2934 to make it easier to monitor when daemon threads have completed
2935 processing all enqueued tasks. Patch #1455676.
2936
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002937- popen2.Popen objects now preserve the command in a .cmd attribute.

2940
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002941- email 4.0 package now integrated. This is largely the same as the email 3.0
2942 package that was included in Python 2.3, except that PEP 8 module names are
2943 now used (e.g. mail.message instead of email.Message). The MIME classes
2944 have been moved to a subpackage (e.g. email.mime.text instead of
2945 email.MIMEText). The old names are still supported for now. Several
2946 deprecated Message methods have been removed and lots of bugs have been
2947 fixed. More details can be found in the email package documentation.
2948
Walter Dörwald40108c92006-03-27 08:15:44 +00002949- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2950 (a subclass of tuple) that provides incremental decoders and encoders
2951 (a way to use stateful codecs without the stream API). Python functions
2952 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2953 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2954 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002955
Walter Dörwald067db482006-03-15 22:17:27 +00002956- Patch #1359365: Calling next() on a closed StringIO.String object raises
2957 a ValueError instead of a StopIteration now (like file and cString.String do).
2958 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2959 called before (like file and StringIO.StringIO do).

3034 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
3035 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
3036 Ronald L. Rivest offered this advice for Python:
3037
3038 "The consensus of researchers in this area (at least as
3039 expressed at the NIST Hash Function Workshop 10/31/05),
3040 is that SHA-256 is a good choice for the time being, but
3041 that research should continue, and other alternatives may
3042 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00003043
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00003044- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandl5284b532005-06-26 22:54:58 +00003128
Georg Brandl2f210b62005-06-26 22:09:06 +00003129- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
3130
Georg Brandlfbff1bc2005-06-26 21:36:25 +00003131- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
3132 error messages.
3133
Georg Brandl379f99d2005-06-26 21:09:38 +00003134- Bug #1108948: Cookie.py produced invalid JavaScript code.
3135
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00003136- The tokenize module now detects and reports indentation errors.
3137 Bug #1224621.
3138
Raymond Hettinger68c04532005-06-10 11:05:19 +00003139- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00003140 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00003141 the generate_tokens() function now accepts a callable argument that
3142 terminates by raising StopIteration.
3143
Georg Brandl9166e1a2005-06-04 09:20:03 +00003144- Bug #1196315: fix weakref.WeakValueDictionary constructor.
3145
Georg Brandl268e61c2005-06-03 14:28:50 +00003146- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
3147 component of the path.
3148
Skip Montanaro174dd222005-05-14 20:54:16 +00003149- Patch #1120353: The xmlrpclib module provides better, more transparent,
3150 support for datetime.{datetime,date,time} objects. With use_datetime set
3151 to True, applications shouldn't have to fiddle with the DateTime wrapper
3152 class at all.
3153
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00003154- distutils.commands.upload was added to support uploading distribution
3155 files to PyPI.
3156
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00003157- distutils.commands.register now encodes the data as UTF-8 before posting
3158 them to PyPI.
3159
Raymond Hettinger267b8682005-03-27 10:47:39 +00003160- decimal operator and comparison methods now return NotImplemented
3161 instead of raising a TypeError when interacting with other types. This
3162 allows other classes to implement __radd__ style methods and have them
3163 work as expected.
3164
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00003165- Bug #1163325: Decimal infinities failed to hash. Attempting to
3166 hash a NaN raised an InvalidOperation instead of a TypeError.
3167
Tim Petersecc6e6a2005-07-10 22:30:55 +00003168- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00003169 stream compression; add, for symmetry reasons, r:* as a synonym of r.
3170
Martin v. Löwis00a73e72005-03-04 19:40:34 +00003171- Patch #1043890: Add extractall method to tarfile.

3174 to build.
3175
Martin v. Löwis637431b2005-03-03 23:12:42 +00003176- Patch #1103407: Properly deal with tarfile iterators when untarring
3177 symbolic links on Windows.

3200
Raymond Hettingerbab41432005-02-05 01:31:19 +00003201- Fixed bug in a NameError bug in cookielib. Patch #1116583.
3202
Guido van Rossumd0641422005-02-03 15:01:24 +00003203- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
3204 disables recursive traversal through instance attributes, which can
3205 be exploited in various ways.
3206
Tim Peterse3547fd2005-12-16 23:13:57 +00003207- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00003208 flags on the HTTP listening socket.
3209
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00003210- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
3211 Fixed by reading the HTTP body in chunks instead of one big socket.read().
3212
Fred Drakefbdeaad2006-07-29 16:56:15 +00003213- Patches #893642, #1039083: add allow_none, encoding arguments to
3214 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00003215
Martin v. Löwis1d11de62005-01-29 13:29:23 +00003216- Bug #1110478: Revert os.environ.update to do putenv again.
3217
Thomas Hellerd6c6e222005-01-20 19:20:16 +00003218- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
3219
Martin v. Löwis22b457e2005-01-16 08:40:58 +00003220- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
3221
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003222- Enhancements to the csv module:
3223
3224 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003225 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003226 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003227 + Dialect parameter parsing has been re-implemented to improve error
3228 reporting.
3229 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3230 dictates.
3231 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003232 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003233 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003234 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3235 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003236 + reader now allows \r characters to be quoted (previously it only allowed
3237 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003238 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003239 + Dialect classes passed to the module are no longer instantiated by
3240 the module before being parsed (the former validation scheme required
3241 this, but the mechanism was unreliable).
3242 + The dialect registry now contains instances of the internal
3243 C-coded dialect type, rather than references to python objects.
3244 + the internal c-coded dialect type is now immutable.
3245 + register_dialect now accepts the same keyword dialect specifications
3246 as the reader and writer, allowing the user to register dialects
3247 without first creating a dialect class.
3248 + a configurable limit to the size of parsed fields has been added -
3249 previously, an unmatched quote character could result in the entire
3250 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003251 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003252 the parser field size limit (returning the former limit). The initial
3253 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003254 + A line_num attribute has been added to the reader object, which tracks
3255 the number of lines read from the source iterator. This is not
3256 the same as the number of records returned, as records can span
3257 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003258 + reader and writer objects were not being registered with the cyclic-GC.
3259 This has been fixed.
3260
Brett Cannone6539c42005-01-08 02:43:53 +00003261- _DummyThread objects in the threading module now delete self.__block that is
3262 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3263 lock primitives tend to be limited in number and thus should not be wasted on
3264 a _DummyThread object. Fixes bug #1089632.
3265
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003266- The imghdr module now detects Exif files.
3267
Raymond Hettinger6065d322004-12-20 23:51:53 +00003268- StringIO.truncate() now correctly adjusts the size attribute.
3269 (Bug #951915).
3270
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003271- locale.py now uses an updated locale alias table (built using
3272 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3273 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003274 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003275
Raymond Hettinger3557f422004-12-07 12:02:02 +00003276- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3277
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003278- the pickle module no longer accepts the deprecated None option in the
3279 args tuple returned by __reduce__().
3280
Brett Cannon84667c02004-12-07 03:25:18 +00003281- optparse now optionally imports gettext. This allows its use in setup.py.
3282
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003283- the pickle module no longer uses the deprecated bin parameter.
3284
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003285- the shelve module no longer uses the deprecated binary parameter.
3286
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003287- the pstats module no longer uses the deprecated ignore() method.
3288
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003289- the filecmp module no longer uses the deprecated use_statcache argument.
3290
Raymond Hettinger664347b2004-12-04 21:21:53 +00003291- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3292 extended or overridden by subclasses. Formerly, the subclassed method would
3293 be ignored by the rest of the module. (Bug #1078905).
3294
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003295- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003296 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003297
Walter Dörwald36733692004-12-22 12:50:50 +00003298- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3299 once when a size argument is given. This prevents a buffer overflow in the
3300 tokenizer with very long source lines.
3301
Barry Warsaw538561e2006-01-01 21:48:54 +00003302- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3303 immediately after creating the object, without any intervening
3304 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003305
Skip Montanaro05885812005-01-16 20:48:27 +00003306- The reconvert.quote function can now emit triple-quoted strings. The
3307 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003308
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003309- ``UserString.MutableString`` now supports negative indices in
3310 ``__setitem__`` and ``__delitem__``
3311
Greg Ward40407942005-03-05 02:53:17 +00003312- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3313 correctly.
3314
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003315- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3316 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3317 character even if the user has passed a size parameter to get a proper
3318 line ending. Remove the special handling of a "\r\n" that has been split
3319 between two lines.
3320
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003321- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3322 about illegal code points. The codec now supports PEP 293 style error
3323 handlers.
3324
Walter Dörwald78a78b02005-09-01 12:04:29 +00003325- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003326 from the input stream, so that the output is a byte string in the correct
3327 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003328
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003329- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3330 considering it exactly like a '*'.
3331
Walter Dörwald007f8df2005-10-09 19:42:27 +00003332- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3333 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003334
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003335- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3336
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003337- Patch #1413711: Certain patterns of differences were making difflib
3338 touch the recursion limit.
3339
Walter Dörwald58917a62006-03-31 15:26:22 +00003340- Bug #947906: An object oriented interface has been added to the calendar
3341 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003342 called as a script (e.g. via ``python -mcalendar``). Localized month and
3343 weekday names can be ouput (even if an exotic encoding is used) using
3344 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003345

Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003360- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3361 The zlib module is now builtin on Windows.
3362
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003363- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3364
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003365- Bug #1189330: configure did not correctly determine the necessary
3366 value of LINKCC if python was built with GCC 4.0.
3367
Trent Mick8321b422005-07-26 02:29:21 +00003368- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3369 vulnerability in zlib 1.2.1 and 1.2.2.
3370
Brett Cannon08cd5982005-04-24 22:26:38 +00003371- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3372 flags that change binary compatibility. Changes were also made to
3373 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003374 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003375
Bob Ippolitoed233462005-03-29 13:47:59 +00003376- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3377 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3378 no longer exists). This configure patch makes things right.
3379
Martin v. Löwise2713be2005-03-08 15:03:08 +00003380- Bug #1158607: Build with --disable-unicode again.
3381
Brett Cannon46d96232005-02-16 00:07:19 +00003382- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3383 defined. Discovered as a result of not being able to build on OS X.
3384
Brett Cannon516592f2004-12-07 00:42:59 +00003385- setup.py now uses the directories specified in LDFLAGS using the -L option
3386 and in CPPFLAGS using the -I option for adding library and include
3387 directories, respectively, for compiling extension modules against. This has
3388 led to the core being compiled using the values in CPPFLAGS. It also removes
3389 the need for the special-casing of both DarwinPorts and Fink for darwin since
3390 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3391 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3392 Fink, ``-I/opt/local/include`` for DarwinPorts).

Brett Cannon43802422005-02-10 20:48:03 +00003394- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3395 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3396 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3397 Closes bug #1096244. Thanks Gregory Bond.

Tim Petersc9d78aa2006-03-26 23:27:58 +00003402- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3403 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3404 is obtained via the ``PyObject_`` family, it must be released via the
3405 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3406 always been officially true, but when Python's small-object allocator was
3407 introduced, an attempt was made to cater to a few extension modules
3408 discovered at the time that obtained memory via ``PyObject_New`` but
3409 released it via ``PyMem_DEL``. It's years later, and if such code still
3410 exists it will fail now (probably with segfaults, but calling wrong
3411 low-level memory management functions can yield many symptoms).
3412
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003413- Added a C API for set and frozenset objects.

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003417- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3418 mapping argument now. This string is used as a mapping table. Byte values
3419 greater than the length of the string and 0xFFFE are treated as undefined
3420 mappings.
