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

122 holds the last (strong) reference to its referent.
123
Guido van Rossumaa975432008-04-10 22:43:58 +0000124- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
125 having a self-referential tuple, which is possible from C code. Nor did
126 object's tp_str consider that a type's tp_str could do something that could
127 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
128 respectively, fixed the issues. (Backport of r58288 from trunk.)

134 reference on the outer class name.
135
Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +0000136- Issue #1477: With narrow Unicode builds, the unicode escape sequence
137 \Uxxxxxxxx did not accept values outside the Basic Multilingual Plane. This
138 affected raw unicode literals and the 'raw-unicode-escape' codec. Now
139 UTF-16 surrogates are generated in this case, like normal unicode literals
140 and the 'unicode-escape' codec.
141
Neal Norwitzb3635f92008-03-18 04:17:36 +0000142- Issue #2321: use pymalloc for unicode object string data to reduce
143 memory usage in some circumstances.
Andrew M. Kuchlingbe0adfc2008-02-23 17:18:19 +0000144
Sean Reifscheider4af861c2008-03-20 17:39:31 +0000145- Issue #2238: Some syntax errors in *args and **kwargs expressions could give

149 parameter but was not verifying that it was greater than zero. Values
150 less than zero will now raise a SystemError and return NULL to indicate a
151 bug in the calling C code.
152
Gregory P. Smith9aa040d2008-06-02 00:07:25 +0000153- Issue #2588, #2589: Fix potential integer underflow and overflow

155
Gregory P. Smithcae7f882008-09-07 06:44:12 +0000156- Issue #1204: The configure script now tests for additional libraries
157 that may be required when linking against readline. This fixes issues
158 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
Georg Brandld9f1da02008-03-29 01:50:46 +0000159

1187-----------------
1188
Neal Norwitz0bcafac2006-09-11 08:51:17 +00001189- Make _PyGILState_NoteThreadState() static, it was not used anywhere
1190 outside of pystate.c and should not be necessary.
1191
Brett Cannon19d76c52006-09-09 07:18:44 +00001192- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
1193 allows calling unicode() on exceptions classes directly to succeed.
1194
Georg Brandlecab6232006-09-06 06:47:02 +00001195- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
1196 Also make sure that every exception class has __module__ set to
1197 'exceptions'.
1198
Georg Brandl37a9e572006-09-06 06:09:34 +00001199- Bug #1550983: emit better error messages for erroneous relative
1200 imports (if not in package and if beyond toplevel package).
1201
Tim Peterscbdd3502006-09-05 01:47:53 +00001202- Overflow checking code in integer division ran afoul of new gcc

1209
Neal Norwitz29a5fdb2006-09-05 02:21:38 +00001210- The return tuple from str.rpartition(sep) is (tail, sep, head) where
1211 head is the original string if sep was not found.
1212
Neal Norwitz3b3aae02006-09-05 03:56:01 +00001213- Bug #1520864: unpacking singleton tuples in list comprehensions and
1214 generator expressions (x for x, in ... ) works again. Fixing this problem
1215 required changing the .pyc magic number. This means that .pyc files
1216 generated before 2.5c2 will be regenerated.

1329-----------------
1330
Neal Norwitz24b6f202006-09-05 04:43:56 +00001331- Fix infinite recursion when subclassing long and overriding __hash__.
1332
1333- Fix concatenation (+=) of long strings.
1334
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001335- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001336 compared equal or unequal to a string and a UnicodeDecodeError
1337 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001338
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001339 Instead, the equal (==) and unequal (!=) comparison operators will
1340 now issue a UnicodeWarning and interpret the two objects as
1341 unequal. The UnicodeWarning can be filtered as desired using
1342 the warning framework, e.g. silenced completely, turned into an
1343 exception, logged, etc.
1344
1345 Note that compare operators other than equal and unequal will still
1346 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001347
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001348- Fix segfault when doing string formatting on subclasses of long.
1349
1350- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1351 with new-style classes.
1352
1353- Fix bug related to __len__ functions returning negative values with
1354 classic classes.
1355
1356- Patch #1538606, Fix __index__() clipping. There were some problems
1357 discovered with the API and how integers that didn't fit into Py_ssize_t
1358 were handled. This patch attempts to provide enough alternatives
1359 to effectively use __index__.
1360
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001361- Bug #1536021: __hash__ may now return long int; the final hash
1362 value is obtained by invoking hash on the long int.
1363
Thomas Hellerab1049c2006-08-08 17:37:00 +00001364- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1365
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001366- Bug #1535165: fixed a segfault in input() and raw_input() when
1367 sys.stdin is closed.
1368
Thomas Heller74d36f02006-08-04 18:17:40 +00001369- On Windows, the PyErr_Warn function is now exported from
1370 the Python dll again.
1371
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001372- Bug #1191458: tracing over for loops now produces a line event
1373 on each iteration. Fixing this problem required changing the .pyc
1374 magic number. This means that .pyc files generated before 2.5c1
1375 will be regenerated.
1376
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001377- Bug #1333982: string/number constants were inappropriately stored
1378 in the byte code and co_consts even if they were not used, ie
1379 immediately popped off the stack.
1380
Georg Brandle9462c72006-08-04 18:03:37 +00001381- Fixed a reference-counting problem in property().

1384Library
1385-------
1386
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001387- Fix a bug in the ``compiler`` package that caused invalid code to be
1388 generated for generator expressions.
1389
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001390- The distutils version has been changed to 2.5.0. The change to
1391 keep it programmatically in sync with the Python version running
1392 the code (introduced in 2.5b3) has been reverted. It will continue
1393 to be maintained manually as static string literal.
1394
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001395- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001396 and this cannot be converted to the required C type, an exception is
1397 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001398 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001399
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001400- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001401 an exception.
1402
Tim Peterscbdd3502006-09-05 01:47:53 +00001403- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001404 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001405 workarounds for clocks with low resolution, to stop the code yielding
1406 duplicate UUIDs.
1407
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001408- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1409 before raising SystemExit, allowing IDLE to honor quit() and exit().
1410
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001411- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1412
Georg Brandl7a1af772006-08-14 21:55:28 +00001413- Patch #1536071: trace.py should now find the full module name of a
1414 file correctly even on Windows.
1415
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001416- logging's atexit hook now runs even if the rest of the module has
1417 already been cleaned up.
1418
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001419- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001420
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001421- Bug #1531405, format_exception no longer raises an exception if
1422 str(exception) raised an exception.
1423
Neil Schemenauer06ded092006-08-04 16:20:30 +00001424- Fix a bug in the ``compiler`` package that caused invalid code to be
1425 generated for nested functions.

1437
Thomas Heller1ce433e2006-08-14 16:20:04 +00001438- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The

Thomas Heller86720042006-08-14 11:17:48 +00001441- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1442 uses the _as_parameter_ attribute when objects are passed to foreign
1443 function calls. The ctypes version number was changed to 1.0.1.

1497Core and builtins
1498-----------------
1499
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001500- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001501 returned a long (see PEP 353).
1502
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001503- Bug #1515471: string.replace() accepts character buffers again.
1504
Neal Norwitz07aadb12006-07-30 06:55:48 +00001505- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1506 This provides the proper warning for struct.pack().
1507 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1508
Neal Norwitz0d62a062006-07-30 06:53:31 +00001509- Patch #1531113: Fix augmented assignment with yield expressions.
1510 Also fix a SystemError when trying to assign to yield expressions.
1511
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001512- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1513 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1514 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1515 excessive filesystem operations during imports.
1516
Tim Petersbc24eee2006-07-27 01:14:53 +00001517- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1518 operations on signed longs that are formally undefined by C.
1519 Unfortunately, at least one compiler now cares about that, so complicated
1520 the code to make that compiler happy again.
1521
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001522- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1523
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001524- Patch #1232023: Stop including current directory in search
1525 path on Windows.
1526
Neal Norwitze1fdb322006-07-21 05:32:28 +00001527- Fix some potential crashes found with failmalloc.
1528
Neal Norwitze7563102006-07-17 01:00:16 +00001529- Fix warnings reported by Klocwork's static analysis tool.
1530
Neal Norwitz84be93b2006-07-16 01:50:38 +00001531- Bug #1512814, Fix incorrect lineno's when code within a function
1532 had more than 255 blank lines.
1533
Georg Brandl9dceedb2006-07-12 15:31:17 +00001534- Patch #1521179: Python now accepts the standard options ``--help`` and
1535 ``--version`` as well as ``/?`` on Windows.
1536
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001537- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001538 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001539 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001540
Tim Peters112aad32006-07-19 00:03:19 +00001541- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001542 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001543 new ``sys._current_frames()`` returns a dictionary with one entry,
1544 mapping the faux "thread id" 0 to the current frame.
1545
Ronald Oussoren3075e162006-07-25 20:28:55 +00001546- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

1550-------
1551
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001552- Correction of patch #1455898: In the mbcs decoder, set final=False
1553 for stream decoder, but final=True for the decode function.
1554
Georg Brandl07fec3a2006-08-01 18:49:24 +00001555- os.urandom no longer masks unrelated exceptions like SystemExit or
1556 KeyboardInterrupt.
1557
Tim Peters4643c2f2006-08-10 22:45:34 +00001558- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001559 shutil.copytree on Windows
1560
Georg Brandle34ac7c2006-07-30 11:07:23 +00001561- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1562 refers to file descriptors, not file objects.
1563
Tim Peterscbdd3502006-09-05 01:47:53 +00001564- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001565 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001566 #1513611, and probably others.
1567
Georg Brandledd9b0d2006-07-29 09:33:26 +00001568- Bug #1441397: The compiler module now recognizes module and function
1569 docstrings correctly as it did in Python 2.4.
1570
Tim Peters6f681472006-07-27 23:44:37 +00001571- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1572 lost that tests are sorted by name before being run. This rarely
1573 matters for well-written tests, but can create baffling symptoms if
1574 side effects from one test to the next affect outcomes. ``DocTestFinder``
1575 has been changed to sort the list of tests it returns.
1576
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001577- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001578 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001579
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001580- Bug #978833: Really close underlying socket in _socketobject.close.
1581
Georg Brandldb232dc2006-08-20 13:15:43 +00001582- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1583 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001584
Georg Brandlcf0c1722006-07-26 07:23:32 +00001585- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1586 to recursive calls and call it with the failing package name.
1587
Martin v. Löwis0b483032006-07-25 09:53:12 +00001588- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1589
Georg Brandlc13c34c2006-07-24 14:09:56 +00001590- Patch #1515343: Fix printing of deprecated string exceptions with a
1591 value in the traceback module.
1592
Greg Ward48fae7a2006-07-23 16:05:51 +00001593- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1594
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001595- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1596
Brett Cannoncaebe222006-07-18 04:41:36 +00001597- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1598 argument tuple. For arguments where zero is illegal, the value is forced to
1599 the minimum value that is correct. This is to support an undocumented but
1600 common way people used to fill in inconsequential information in the time
1601 tuple pre-2.4.
1602
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001603- Patch #1220874: Update the binhex module for Mach-O.
1604
Barry Warsawb110bad2006-07-21 14:51:07 +00001605- The email package has improved RFC 2231 support, specifically for
1606 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1607 (name*0=<blah>) parameter continuations. This may change the types of
1608 values returned from email.message.Message.get_param() and friends.
1609 Specifically in some cases where non-encoded continuations were used,
1610 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1611 will just return the string (since non-encoded continuations don't have
1612 charset and language parts).
1613
1614 Also, whereas % values were decoded in all parameter continuations, they are
1615 now only decoded in encoded parameter parts.
1616
Ronald Oussoren3075e162006-07-25 20:28:55 +00001617- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1618
1619- Bug #1517996: IDLE now longer shows the default Tk menu when a
1620 path browser, class browser or debugger is the frontmost window on MacOS X
1621
Barry Warsaw00decd72006-07-27 23:43:15 +00001622- Patch #1520294: Support for getset and member descriptors in types.py,
1623 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1624 of an object against these built-in types and more importantly, for getting
1625 their docstrings printed in the interactive interpreter's help() function.

1629-----------------
1630
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001631- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1632 a socket operation on a socket with a timeout, the exception will be
1633 caught correctly. Previously, the exception was not caught.
1634
Thomas Heller1393d6a2006-07-28 21:43:20 +00001635- Patch #1529514: The _ctypes extension is now compiled on more
1636 openbsd target platforms.
1637
Tim Peters9cab5932006-07-28 00:30:00 +00001638- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1639 a memory leak, affecting pickles and deep copies.
1640
Tim Petersbc24eee2006-07-27 01:14:53 +00001641- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1643
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001644- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1645
Thomas Hellerce049a02006-07-14 17:51:14 +00001646- Patch #1521817: Index range checking on ctypes arrays containing
1647 exactly one element enabled again. This allows iterating over these
1648 arrays, without the need to check the array size before.
1649
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001650- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001651 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001652 /dev/null in certain cases; this is now fixed.
1653
Thomas Heller47d7a062006-07-12 08:43:47 +00001654- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1655 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001656
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001657- Because of a misspelled preprocessor symbol, ctypes was always
1658 compiled without thread support; this is now fixed.
1659
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001660- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1661 methods now allow their database parameter to be None as the
1662 sleepycat API allows.
1663
Matt Flemingec926502006-07-28 11:27:27 +00001664- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1665 bluetooth API compared with Linux and FreeBSD.

1668-----
1669
1670- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1671 how long the test file should take to play. Now accepts taking 2.93 secs
1672 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1673
Georg Brandl4793aa32006-07-28 18:31:39 +00001674- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1675 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1676 run via ``regrtest.py``. Now they do.

1685
1686- PythonLauncher now works correctly when the path to the script contains
1687 characters that are treated specially by the shell (such as quotes).
1688
1689- Bug #1527397: PythonLauncher now launches scripts with the working directory
1690 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001691 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001692 expect.

Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001703- Bug #1441486: The literal representation of -(sys.maxint - 1)
1704 again evaluates to a int object, not a long.
1705
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001706- Bug #1501934: The scope of global variables that are locally assigned
1707 using augmented assignment is now correctly determined.
1708
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001709- Bug #927248: Recursive method-wrapper objects can now safely
1710 be released.

Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001712- Bug #1417699: Reject locale-specific decimal point in float()
1713 and atof().
1714
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001715- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1716 omit a default "error" argument for NULL pointer. This allows
1717 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001718
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001719- Bug #1519018: 'as' is now validated properly in import statements.
1720
Neal Norwitz28746ab2006-07-09 22:14:42 +00001721- On 64 bit systems, int literals that use less than 64 bits are
1722 now ints rather than longs.
1723
Neal Norwitzed657552006-07-10 00:04:44 +00001724- Bug #1512814, Fix incorrect lineno's when code at module scope
1725 started after line 256.
1726
Tim Peters32a83612006-07-10 21:08:24 +00001727- New function ``sys._current_frames()`` returns a dict mapping thread
1728 id to topmost thread stack frame. This is for expert use, and is
1729 especially useful for debugging application deadlocks. The functionality
1730 was previously available in Fazal Majid's ``threadframe`` extension
1731 module, but it wasn't possible to do this in a wholly threadsafe way from
1732 an extension.

1749
Thomas Woutersadd19112006-07-05 11:03:49 +00001750- string.Template() now correctly handles tuple-values. Previously,
1751 multi-value tuples would raise an exception and single-value tuples would
1752 be treated as the value they contain, instead.
1753
Martin v. Löwisede77f52006-07-03 13:01:35 +00001754- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1779
Brett Cannon53ab5b72006-06-22 16:49:14 +00001780- Bug #1510580: The 'warnings' module improperly required that a Warning
1781 category be either a types.ClassType and a subclass of Warning. The proper
1782 check is just that it is a subclass with Warning as the documentation states.
1783
Georg Brandlad29e632006-06-21 17:45:17 +00001784- The compiler module now correctly compiles the new try-except-finally
1785 statement (bug #1509132).
1786
Neal Norwitz60373cd2006-06-22 06:30:50 +00001787- The wsgiref package is now installed properly on Unix.
1788

1791
Gerhard Häring762fbd32006-07-02 17:48:30 +00001792- The sqlite3 module did cut off data from the SQLite database at the first
1793 null character before sending it to a custom converter. This has been fixed
1794 now.
1795
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001796Extension Modules
1797-----------------
1798
Tim Peters112aad32006-07-19 00:03:19 +00001799- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1800 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1801 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001802
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001803- Assigning None to pointer type fields in ctypes structures possible
1804 overwrote the wrong fields, this is fixed now.
1805
1806- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1807 on non-Windows platforms.
1808
1809- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1810 integer or long, without range checking.
1811
1812- Patch #1517790: It is now possible to use custom objects in the ctypes
1813 foreign function argtypes sequence as long as they provide a from_param
1814 method, no longer is it required that the object is a ctypes type.
1815
1816- The '_ctypes' extension module now works when Python is configured
1817 with the --without-threads option.
1818
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001819- Bug #1513646: os.access on Windows now correctly determines write
1820 access, again.
1821
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001822- Bug #1512695: cPickle.loads could crash if it was interrupted with
1823 a KeyboardInterrupt.
1824
Neal Norwitza12aa882006-07-06 06:45:08 +00001825- Bug #1296433: parsing XML with a non-default encoding and
1826 a CharacterDataHandler could crash the interpreter in pyexpat.
1827
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001828- Patch #1516912: improve Modules support for OpenVMS.

1831-----
1832
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001833- Automate Windows build process for the Win64 SSL module.
1834
Tim Peters32a83612006-07-10 21:08:24 +00001835- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001836 Previously, the slight difference could cause compilation errors of the
1837 'zlib' module on systems with more than one version of zlib.
1838
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001839- The MSI compileall step was fixed to also support a TARGETDIR

1843 of Tcl/Tk.
1844
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001845- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001846 trying to be installed even though it's empty.

1858 documentation for the warnings module.
1859
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001860- Patch #1509163: MS Toolkit Compiler no longer available.

1870Core and builtins
1871-----------------
1872
Georg Brandla56b9152006-06-19 06:35:54 +00001873- Patch #1507676: Error messages returned by invalid abstract object operations
1874 (such as iterating over an integer) have been improved and now include the
1875 type of the offending object to help with debugging.
1876
Brett Cannonea3912b2006-06-13 21:46:41 +00001877- Bug #992017: A classic class that defined a __coerce__() method that returned
1878 its arguments swapped would infinitely recurse and segfault the interpreter.
1879
Neal Norwitz909eb122006-06-12 02:13:21 +00001880- Fix the socket tests so they can be run concurrently.
1881
Neal Norwitzb9845e72006-06-12 02:11:18 +00001882- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001883 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001884
Brett Cannon22565aa2006-06-09 22:31:23 +00001885- Bug #532646: object.__call__() will continue looking for the __call__
1886 attribute on objects until one without one is found. This leads to recursion
1887 when you take a class and set its __call__ attribute to an instance of the
1888 class. Originally fixed for classic classes, but this fix is for new-style.
1889 Removes the infinite_rec_3 crasher.
1890
Georg Brandl24250812006-06-09 18:45:48 +00001891- The string and unicode methods startswith() and endswith() now accept
1892 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1893
Brett Cannonde3b0522006-06-08 17:00:45 +00001894- Buffer objects, at the C level, never used the char buffer
1895 implementation even when the char buffer for the wrapped object was
1896 explicitly requested (originally returned the read or write buffer).
1897 Now a TypeError is raised if the char buffer is not present but is
1898 requested.
1899
Georg Brandlddbaa662006-06-04 21:56:52 +00001900- Patch #1346214: Statements like "if 0: suite" are now again optimized
1901 away like they were in Python 2.4.
1902
Georg Brandlb7c8f542006-05-27 12:30:25 +00001903- Builtin exceptions are now full-blown new-style classes instead of
1904 instances pretending to be classes, which speeds up exception handling
1905 by about 80% in comparison to 2.5a2.
1906
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001907- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1908 Unicode 4.1.
1909
Georg Brandlf4ef1162006-05-26 18:03:31 +00001910- Patch #921466: sys.path_importer_cache is now used to cache valid and
1911 invalid file paths for the built-in import machinery which leads to
1912 fewer open calls on startup.
1913
Tim Peters696cf432006-05-24 21:10:40 +00001914- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1915 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1916 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1917 the number of input digits (it was and remains linear-time for bases
1918 2, 4, 8, 16 and 32).
1919
Tim Petersb713ec22006-05-23 18:45:30 +00001920- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1921 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1922 an integer close to ``sys.maxint``. This was repaired by patch
1923 #1335972, which also gives a nice speedup.
1924
Richard Jonescebbefc2006-05-23 18:28:17 +00001925- Patch #1337051: reduced size of frame objects.
1926
1927- PyErr_NewException now accepts a tuple of base classes as its
1928 "base" parameter.
1929
Richard Jones7c88dcc2006-05-23 10:37:38 +00001930- Patch #876206: function call speedup by retaining allocated frame
1931 objects.
1932
Georg Brandl7b90e162006-05-18 07:01:27 +00001933- Bug #1462152: file() now checks more thoroughly for invalid mode
1934 strings and removes a possible "U" before passing the mode to the
1935 C library function.
1936
Neal Norwitz1004a532006-05-15 07:17:23 +00001937- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1938
Neal Norwitz373f0a72006-05-15 07:04:36 +00001939- Bug #1487966: Fix SystemError with conditional expression in assignment
1940
Martin v. Löwis879768d2006-05-11 13:28:43 +00001941- WindowsError now has two error code attributes: errno, which carries
1942 the error values from errno.h, and winerror, which carries the error
1943 values from winerror.h. Previous versions put the winerror.h values
1944 (from GetLastError()) into the errno attribute.
1945
Martin v. Löwis77736712006-05-04 05:51:03 +00001946- Patch #1475845: Raise IndentationError for unexpected indent.
1947
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001948- Patch #1479181: split open() and file() from being aliases for each other.
1949
Tim Peters44bd9862006-06-01 13:49:23 +00001950- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1951 methods were always silently ignored by dictionaries when comparing keys.
1952 They are now passed through (except when using the C API function
1953 ``PyDict_GetItem()``, whose semantics did not change).
1954
1955- Bug #1456209: In some obscure cases it was possible for a class with a
1956 custom ``__eq__()`` method to confuse dict internals when class instances
1957 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1958 No, you don't have any code that did this ;-)

1966
Brett Cannon6ee7d012006-06-08 16:23:04 +00001967- Change binascii.hexlify to accept a read-only buffer instead of only a char
1968 buffer and actually follow its documentation.
1969
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001970- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1971
Nick Coghlanc649ec52006-05-29 12:43:05 +00001972- Patch #1478788 (modified version): The functional extension module has
1973 been renamed to _functools and a functools Python wrapper module added.
1974 This provides a home for additional function related utilities that are
1975 not specifically about functional programming. See PEP 309.
1976
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001977- Patch #1493701: performance enhancements for struct module.

Georg Brandl8d3342b2006-05-16 07:38:27 +00001981- Patch #1435422: zlib's compress and decompress objects now have a
1982 copy() method.
1983
Andrew MacIntyre92913322006-06-13 15:04:24 +00001984- Patch #1454481: thread stack size is now tunable at runtime for thread
1985 enabled builds on Windows and systems with Posix threads support.
1986
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001987- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1988 (up to the system limit of 32K characters).
1989
1990- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1991 As a result, these functions now raise WindowsError instead of OSError.
1992
Tim Peters7a822da2006-05-25 21:50:17 +00001993- ``time.clock()`` on Win64 should use the high-performance Windows
1994 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1995 Windows platforms).
1996
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001997- Calling Tk_Init twice is refused if the first call failed as that
1998 may deadlock.
1999
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00002000- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
2001 accept it without potentially using an uninitialized pointer.
2002
2003- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
2004 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
2005 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00002006
Gregory P. Smith372b5832006-06-05 18:48:21 +00002007- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00002008 [pybsddb project SF patch number 1466734]

2012
Gregory P. Smith3c228b12006-06-05 23:59:37 +00002013- bsddb: the __len__ method of a DB object has been fixed to return correct
2014 results. It could previously incorrectly return 0 in some cases.
2015 Fixes SF bug 1493322 (pybsddb bug 1184012).
2016
Gregory P. Smithff7d9912006-06-08 05:17:08 +00002017- bsddb: the bsddb.dbtables Modify method now raises the proper error and
2018 aborts the db transaction safely when a modifier callback fails.
2019 Fixes SF python patch/bug #1408584.
2020
Gregory P. Smith506f7b52006-06-15 08:52:32 +00002021- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00002022 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00002023 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
2024 database calls that would previously deadlock. [SF python bug #775414]

Georg Brandl2605ca82006-06-14 06:08:31 +00002050- Bug #1339007: Shelf objects now don't raise an exception in their
2051 __del__ method when initialization failed.
2052
Martin v. Löwisd8251432006-06-14 05:21:04 +00002053- Patch #1455898: The MBCS codec now supports the incremental mode for
2054 double-byte encodings.
2055
Tim Peters43898b42006-06-14 04:09:25 +00002056- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
2057 guarantee that adjacent triples in the return list always describe
2058 non-adjacent blocks. Previously, a pair of matching blocks could end
2059 up being described by multiple adjacent triples that formed a partition
2060 of the matching pair.
2061
Greg Ward0e0c9f42006-06-11 16:24:11 +00002062- Bug #1498146: fix optparse to handle Unicode strings in option help,
2063 description, and epilog.

2068 clarify docs.
2069
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00002070- The wsgiref package has been added to the standard library.
2071
Nick Coghlan676725d2006-06-08 13:54:49 +00002072- The functions update_wrapper() and wraps() have been added to the functools
2073 module. These make it easier to copy relevant metadata from the original
2074 function when writing wrapper functions.
2075
Tim Petersd6a9eef2006-06-05 01:48:21 +00002076- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
2077 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00002078
Martin v. Löwis3f767792006-06-04 19:36:28 +00002079- Patch #1359618: Speed up charmap encoder by using a trie structure
2080 for lookup.
2081
Tim Petersd609b1a2006-06-02 23:22:51 +00002082- The functions in the ``pprint`` module now sort dictionaries by key
2083 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
2084 if and only if its display required more than one line, although that
2085 wasn't documented. The new behavior increases predictability; e.g.,
2086 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
2087

2113 a couple of issues, notably handling of long file names using the
2114 GNU LONGNAME extension.
2115
2116- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
2117 new flag when ``name`` is already the name of an option flag.
2118
2119- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
2120 package.
2121
2122- Patch #1472854: make the rlcompleter.Completer class usable on non-
2123 UNIX platforms.

2160
2161*Release date: 27-APR-2006*
2162
2163Core and builtins
2164-----------------
2165
Thomas Heller1b046642006-04-18 18:51:06 +00002166- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2167 by converting these apis from macros into exported functions again:
2168
2169 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2170 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2171 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
2172 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
2173 PyRun_String Py_CompileString
2174
Martin v. Löwis45294a92006-04-18 06:24:08 +00002175- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2176
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002177- All uses of PyStructSequence_InitType have been changed to initialize
2178 the type objects only once, even if the interpreter is initialized
2179 multiple times.
2180
Neal Norwitz61546162006-04-14 05:20:28 +00002181- Bug #1454485, array.array('u') could crash the interpreter. This was
2182 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2183 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2184
2185- Py_UNICODE is unsigned. It was always documented as unsigned, but
2186 due to a bug had a signed value in previous versions.
2187
Tim Peters3a5e8b12006-04-11 01:44:07 +00002188- Patch #837242: ``id()`` of any Python object always gives a positive
2189 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2190 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002191 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002192 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002193
Tim Peters3a5e8b12006-04-11 01:44:07 +00002194 def __hash__(self):
2195 return id(self) # WRONG
2196
2197 because a hash result must be a (short) Python int but it was always
2198 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002199 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002200 was always usable as a hash value before this patch. That's no longer
2201 necessarily so.
2202
2203- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002204 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002205 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002206 #1454844)
2207
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002208- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2209 involving generators that have paused outside of any ``try`` or ``with``
2210 blocks. (In 2.5a1, a paused generator that was part of a reference
2211 cycle could not be garbage collected, regardless of whether it was
2212 paused in a ``try`` or ``with`` block.)

Tim Peters711bf302006-04-25 03:31:36 +00002244- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2245 a doctest to be skipped (the code is not run, and the expected output
2246 or exception is ignored).
2247
Nick Coghlanda2268f2006-04-24 04:37:15 +00002248- Fixed contextlib.nested to cope with exceptions being raised and
2249 caught inside exit handlers.
2250
Greg Wardab05edc2006-04-23 03:47:58 +00002251- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2252 hex, octal, or binary; add ``append_const`` action; keep going if
2253 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2254 added ``epilog`` for better help generation).
2255
Tim Peters21fbd572006-04-21 21:18:10 +00002256- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2257 called from a thread spawned as a side effect of importing a module.
2258
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002259- The pydoc module now supports documenting packages contained in
2260 .zip or .egg files.
2261
2262- The pkgutil module now has several new utility functions, such
2263 as ``walk_packages()`` to support working with packages that are either
2264 in the filesystem or zip files.
2265
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002266- The mailbox module can now modify and delete messages from

2268 K. Johnson for writing the code, and to the 2005 Google Summer of
2269 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002270
Tim Petersc7605f22006-04-17 21:12:33 +00002271- The ``__del__`` method of class ``local`` in module ``_threading_local``
2272 returned before accomplishing any of its intended cleanup.
2273
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002274- Patch #790710: Add breakpoint command lists in pdb.

Nick Coghlan27ec1a72006-04-24 04:32:47 +00002326- test_cmd_line now checks operation of the -m and -c command switches
2327
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002328- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2329 it separately and by hand. It also wasn't cleaning up its changes to
2330 the current Decimal context.
2331
Thomas Woutersabd08882006-04-26 15:53:30 +00002332- regrtest.py now has a -M option to run tests that test the new limits of
2333 containers, on 64-bit architectures. Running these tests is only sensible
2334 on 64-bit machines with more than two gigabytes of memory. The argument
2335 passed is the maximum amount of memory for the tests to use.

2344-------------
2345
Tim Petersb06d28c2006-05-12 01:57:59 +00002346- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2347
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002348- PEP 343: Added Context Types section to the library reference
2349 and attempted to bring other PEP 343 related documentation into
2350 line with the implementation and/or python-dev discussions.
2351
Tim Peters8dc73d22006-04-24 02:03:16 +00002352- Bug #1337990: clarified that ``doctest`` does not support examples
2353 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002356What's New in Python 2.5 alpha 1?
2357=================================
2358
Anthony Baxterebed3f62006-04-03 15:03:44 +00002359*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002360
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002361Core and builtins
2362-----------------
2363
Nick Coghlan43832302006-04-23 17:04:07 +00002364- PEP 338: -m command line switch now delegates to runpy.run_module
2365 allowing it to support modules in packages and zipfiles
2366
Martin v. Löwisc661b882006-04-20 04:54:23 +00002367- On Windows, .DLL is not an accepted file name extension for
2368 extension modules anymore; extensions are only found if they
2369 end in .PYD.
2370
Martin v. Löwisea62d252006-04-03 10:56:49 +00002371- Bug #1421664: sys.stderr.encoding is now set to the same value as
2372 sys.stdout.encoding.
2373
Neal Norwitz92e212f2006-04-03 04:48:37 +00002374- __import__ accepts keyword arguments.
2375
Georg Brandlccadf842006-03-31 18:54:53 +00002376- Patch #1460496: round() now accepts keyword arguments.
2377
Anthony Baxter262c00a2006-03-30 10:53:17 +00002378- Fixed bug #1459029 - unicode reprs were double-escaped.
2379
Hye-Shik Changd478f342006-03-23 12:32:36 +00002380- Patch #1396919: The system scope threads are reenabled on FreeBSD
2381 5.4 and later versions.
2382
Neal Norwitze98ccf62006-03-23 05:39:47 +00002383- Bug #1115379: Compiling a Unicode string with an encoding declaration
2384 now gives a SyntaxError.
2385
Georg Brandlabd1ff82006-03-18 07:59:59 +00002386- Previously, Python code had no easy way to access the contents of a
2387 cell object. Now, a ``cell_contents`` attribute has been added
2388 (closes patch #1170323).
2389
Tim Peterscf79aac2006-03-16 01:14:46 +00002390- Patch #1123430: Python's small-object allocator now returns an arena to
2391 the system ``free()`` when all memory within an arena becomes unused
2392 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2393 freed. Some applications will see a drop in virtual memory size now,
2394 especially long-running applications that, from time to time, temporarily
2395 use a large number of small objects. Note that when Python returns an
2396 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002397 platform C library will in turn return that memory to the operating system.
2398 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002399 appears to be effective at least on Microsoft C and gcc-based systems.
2400 Thanks to Evan Jones for hard work and patience.
2401
Georg Brandl533ff6f2006-03-08 18:09:27 +00002402- Patch #1434038: property() now uses the getter's docstring if there is
2403 no "doc" argument given. This makes it possible to legitimately use
2404 property() as a decorator to produce a read-only property.
2405
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002406- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2407 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2408 of requiring an int or long in slicing and a few other contexts, enabling
2409 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2410
Neal Norwitz995acdf2006-03-07 05:01:00 +00002411- Fixed various bugs reported by Coverity's Prevent tool.
2412
Brett Cannonbf364092006-03-01 04:25:17 +00002413- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2414 new exception base class, BaseException, which has a new message attribute.
2415 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2416 Raising a string exception now raises a DeprecationWarning.
2417
Thomas Woutersfb609f42006-02-28 16:37:25 +00002418- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2419 explicitly relative, using 'from .module import name' to mean 'from the same
2420 package as this module is in. Imports without dots still default to the
2421 old relative-then-absolute, unless 'from __future__ import
2422 absolute_import' is used.
2423
Brett Cannona7446e32006-02-27 23:39:10 +00002424- Properly check if 'warnings' raises an exception (usually when a filter set
2425 to "error" is triggered) when raising a warning for raising string
2426 exceptions.
2427
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002428- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002429 The name was removed from Include/code.h.
2430
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002431- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002432
Guido van Rossum1968ad32006-02-25 22:38:04 +00002433- Patch 1433928:
2434 - The copy module now "copies" function objects (as atomic objects).
2435 - dict.__getitem__ now looks for a __missing__ hook before raising
2436 KeyError.
2437
Tim Peters84ef21c2006-02-28 20:39:06 +00002438- PEP 343: with statement implemented. Needs ``from __future__ import
2439 with_statement``. Use of 'with' as a variable will generate a warning.
2440 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002441 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002442 The following objects have __context__ methods:
2443 - The built-in file type.
2444 - The thread.LockType type.
2445 - The following types defined by the threading module:
2446 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2447 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002448
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002449- Fix the encodings package codec search function to only search
2450 inside its own package. Fixes problem reported in patch #1433198.
2451
2452 Note: Codec packages should implement and register their own
2453 codec search function. PEP 100 has the details.
2454
Tim Peters9ea89d22006-06-04 03:26:02 +00002455- PEP 353: Using ``Py_ssize_t`` as the index type.
2456
2457- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2458 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2459 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2460 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2461 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002462
Neal Norwitzfc76d632006-01-10 06:03:13 +00002463- Patch #1400181, fix unicode string formatting to not use the locale.
2464 This is how string objects work. u'%f' could use , instead of .
2465 for the decimal point. Now both strings and unicode always use periods.
2466
Neal Norwitz671b9e32006-01-09 07:07:12 +00002467- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2468 configure would break checking curses.h.
2469
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002470- Bug #959576: The pwd module is now builtin. This allows Python to be
2471 built on UNIX platforms without $HOME set.
2472
Neal Norwitzc10978f2005-12-19 06:07:16 +00002473- Bug #1072182, fix some potential problems if characters are signed.
2474
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002475- Bug #889500, fix line number on SyntaxWarning for global declarations.
2476
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002477- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2478
Neal Norwitze7214a12005-12-18 05:03:17 +00002479- Support for converting hex strings to floats no longer works.
2480 This was not portable. float('0x3') now raises a ValueError.
2481
Barry Warsaw2a38a862005-12-18 01:27:35 +00002482- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002483 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002484 is now displayed in interactive prompt banner.
2485
Georg Brandlfa166682005-12-17 21:45:17 +00002486- Implementation of PEP 341 - Unification of try/except and try/finally.
2487 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002488 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002489
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002490- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2491 now encodes backslash correctly.
2492
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002493- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2494
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002495- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002496 and long longs.
2497
Neal Norwitz67715f02005-11-09 06:59:35 +00002498- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002499 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002500 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002501
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002502- Replaced most Unicode charmap codecs with new ones using the
2503 new Unicode translate string feature in the builtin charmap
2504 codec; the codecs were created from the mapping tables available
2505 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2506 encodings now include a mapping for the Apple logo)
2507
Tim Peterse3547fd2005-12-16 23:13:57 +00002508- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002509
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002510- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002511
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002512- A new AST parser implementation was completed. The abstract
2513 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002514 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002515
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002516- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002517 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2518
Neal Norwitz708e51a2005-10-03 04:48:15 +00002519- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2520
Neal Norwitz11bd1192005-10-03 00:54:56 +00002521- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2522 Provide a warning when a directory is passed on the command line.
2523
Neal Norwitz40d37812005-10-02 01:48:49 +00002524- Fix segfault with invalid coding.
2525
2526- SF bug #772896: unknown encoding results in MemoryError.
2527
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002528- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002529 supported a __len__() method which evaluated to False when the iterator
2530 was empty.
2531
Guido van Rossum630db602005-09-20 18:49:54 +00002532- On 64-bit platforms, when __len__() returns a value that cannot be
2533 represented as a C int, raise OverflowError.
2534
Skip Montanarof8948ca2005-09-19 03:54:46 +00002535- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002536 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002537
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002538- SF bug #893549: parsing keyword arguments was broken with a few format
2539 codes.
2540
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002541- Changes donated by Elemental Security to make it work on AIX 5.3
2542 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2543 bug #105470: test_pwd fails on 64bit system (Opteron).
2544
Guido van Rossum539c6622005-09-14 17:49:54 +00002545- Changes donated by Elemental Security to make it work on HP-UX 11 on
2546 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2547
Georg Brandl4550b8d2005-08-26 06:43:52 +00002548- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002549 (fixes bug #1119418).
2550
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002551- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2552
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002553- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2554 exceptions that cause a function to exit.
2555
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002556- The implementation of set() and frozenset() was revised to use its
2557 own internal data structure. Memory consumption is reduced by 1/3
2558 and there are modest speed-ups as well. The API is unchanged.
2559
Tim Petersde7990b2005-07-17 23:45:23 +00002560- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2561
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002562- SF bug #1229429: PyObject_CallMethod failed to decrement some
2563 reference counts in some error exit cases.
2564
Tim Petersecc6e6a2005-07-10 22:30:55 +00002565- SF bug #1185883: Python's small-object memory allocator took over
2566 a block managed by the platform C library whenever a realloc specified
2567 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002568 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002569 portable way to copy data from the C-managed block into Python's
2570 small-object space without risking a memory fault. Python's small-object
2571 realloc now leaves such blocks under the control of the platform C
2572 realloc.
2573
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002574- SF bug #1232517: An overflow error was not detected properly when
2575 attempting to convert a large float to an int in os.utime().
2576
Raymond Hettinger3296e692005-06-29 23:29:56 +00002577- SF bug #1224347: hex longs now print with lowercase letters just
2578 like their int counterparts.
2579
Michael W. Hudson188d4362005-06-20 16:52:57 +00002580- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2581 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2582 interpreter states; back out that fix and do a better job (see
2583 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2584 for a longer write-up of the problem).
2585
Michael W. Hudsondf888462005-06-03 14:41:55 +00002586- SF patch #1180995: marshal now uses a binary format by default when
2587 serializing floats.
2588
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002589- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2590 the routines that promise to produce IEEE 754 binary representations
2591 of floats now simply copy bytes around.
2592
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002593- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2594 278.

Brett Cannonc3647ac2005-04-26 03:45:26 +00002596- patch #1109424: int, long, float, complex, and unicode now check for the
2597 proper magic slot for type conversions when subclassed. Previously the
2598 magic slot was ignored during conversion. Semantics now match the way
2599 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002600 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002601 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002602 Thanks Walter D�rwald.

Barry Warsawc8d907c2005-04-19 23:43:40 +00002604- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2605 NULL, now raise an AttributeError when attempting to set or delete the
2606 attribute. Previously a TypeError was raised, but this was inconsistent
2607 with the equivalent pure-Python implementation.
2608
Michael W. Hudson774479c2005-04-18 08:46:17 +00002609- It is now safe to call PyGILState_Release() before
2610 PyEval_InitThreads() (note that if there is reason to believe there
2611 are multiple threads around you still must call PyEval_InitThreads()
2612 before using the Python API; this fix is for extension modules that
2613 have no way of knowing if Python is multi-threaded yet).
2614
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002615- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2616 disabled caused a crash.
2617
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002618- Bug #1165306: instancemethod_new allowed the creation of a method
2619 with im_class == im_self == NULL, which caused a crash when called.
2620
Tim Petersecc6e6a2005-07-10 22:30:55 +00002621- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002622 fixes the crash seen in bug #1165761
2623
Raymond Hettinger96229b12005-03-11 06:49:40 +00002624- Added two new builtins, any() and all().
2625
Brett Cannon409d8f22005-03-05 06:47:57 +00002626- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002627 (e.g., ``class C(): pass`` is no longer a syntax error).
2628 Patch #1176012 added support to the 'parser' module and 'compiler' package
2629 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002630
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002631- Patch #1115086: Support PY_LONGLONG in structmember.
2632
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002633- Bug #1155938: new style classes did not check that __init__() was
2634 returning None.
2635
Tim Petersecc6e6a2005-07-10 22:30:55 +00002636- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002637 ('\') with a specific error message.
2638
Martin v. Löwisff232d72005-03-03 09:24:38 +00002639- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2640
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002641- Bug #1124295: the __name__ attribute of file objects was
2642 inadvertently made inaccessible in restricted mode.
2643
Tim Petersecc6e6a2005-07-10 22:30:55 +00002644- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002645 an ferror() call.
2646
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002647- min() and max() now support key= arguments with the same meaning as in
2648 list.sort().
2649
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002650- The peephole optimizer now performs simple constant folding in expressions:
2651 (2+3) --> (5).
2652
Raymond Hettingera422c342005-01-11 03:03:27 +00002653- set and frozenset objects can now be marshalled. SF #1098985.
2654
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002655- Bug #1077106: Poor argument checking could cause memory corruption
2656 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002657
Jeremy Hyltonab630502005-02-04 18:44:06 +00002658- The parser did not complain about future statements in illegal
2659 positions. It once again reports a syntax error if a future
2660 statement occurs after anything other than a doc string.
2661
Neil Schemenauercf52c072005-08-12 17:34:58 +00002662- Change the %s format specifier for str objects so that it returns a
2663 unicode instance if the argument is not an instance of basestring and
2664 calling __str__ on the argument returns a unicode instance.
2665
Tim Petersf4e69282006-02-27 17:15:31 +00002666- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2667 current thread state when the auto-GIL-state machinery knows about
2668 it (since the thread state is being deleted, continuing to remember it
2669 can't help, but can hurt if another thread happens to get created with
2670 the same thread id).

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002862- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2863 been renamed to have only a single underscore prefix. This was done to
2864 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002865
Nick Coghlan43832302006-04-23 17:04:07 +00002866- PEP 338: new module runpy defines a run_module function to support
2867 executing modules which provide access to source code or a code object
2868 via the PEP 302 import mechanisms.
2869
Anthony Baxter93f5b932006-04-03 08:05:07 +00002870- The email module's parsedate_tz function now sets the daylight savings
2871 flag to -1 (unknown) since it can't tell from the date whether it should

2878 in attribute values.
2879
Anthony Baxterc51ee692006-04-01 00:57:31 +00002880- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002881 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002882 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002883 module will not be built.
2884
Tim Petersc17976e2006-04-01 00:26:53 +00002885- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2886 aren't officially supported here, and trying to use them will probably
2887 raise an exception some day. But dicts have been allowed, and "mostly
2888 worked", so support for them won't go away without warning.
2889
Georg Brandl338ef7d2006-03-31 18:42:16 +00002890- Bug #1445068: getpass.getpass() can now be given an explicit stream
2891 argument to specify where to write the prompt.
2892
Georg Brandl22ec80b2006-03-31 18:25:44 +00002893- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2899 key to be used for signing the uploaded code.
2900
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002901- Queue.Queue objects now support .task_done() and .join() methods
2902 to make it easier to monitor when daemon threads have completed
2903 processing all enqueued tasks. Patch #1455676.
2904
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002905- popen2.Popen objects now preserve the command in a .cmd attribute.
2906
Thomas Hellerc61c0492006-03-22 10:09:27 +00002907- Added the ctypes ffi package.
2908
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002909- email 4.0 package now integrated. This is largely the same as the email 3.0
2910 package that was included in Python 2.3, except that PEP 8 module names are
2911 now used (e.g. mail.message instead of email.Message). The MIME classes
2912 have been moved to a subpackage (e.g. email.mime.text instead of
2913 email.MIMEText). The old names are still supported for now. Several
2914 deprecated Message methods have been removed and lots of bugs have been
2915 fixed. More details can be found in the email package documentation.
2916
Walter Dörwald40108c92006-03-27 08:15:44 +00002917- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2918 (a subclass of tuple) that provides incremental decoders and encoders
2919 (a way to use stateful codecs without the stream API). Python functions
2920 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2921 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2922 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002923
Walter Dörwald067db482006-03-15 22:17:27 +00002924- Patch #1359365: Calling next() on a closed StringIO.String object raises
2925 a ValueError instead of a StopIteration now (like file and cString.String do).
2926 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2927 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002928
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002929- A regrtest option -w was added to re-run failed tests in verbose mode.

2932 interpreter to exit.
2933
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002934- The function get_count() has been added to the gc module, and gc.collect()

2941 and helpful context managers nested() and closing().
2942

3002 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
3003 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
3004 Ronald L. Rivest offered this advice for Python:
3005
3006 "The consensus of researchers in this area (at least as
3007 expressed at the NIST Hash Function Workshop 10/31/05),
3008 is that SHA-256 is a good choice for the time being, but
3009 that research should continue, and other alternatives may
3010 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00003011
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00003012- Added a subset of Fredrik Lundh's ElementTree package. Available

3123 files to PyPI.
3124
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00003125- distutils.commands.register now encodes the data as UTF-8 before posting
3126 them to PyPI.
3127
Raymond Hettinger267b8682005-03-27 10:47:39 +00003128- decimal operator and comparison methods now return NotImplemented
3129 instead of raising a TypeError when interacting with other types. This
3130 allows other classes to implement __radd__ style methods and have them
3131 work as expected.
3132
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00003133- Bug #1163325: Decimal infinities failed to hash. Attempting to
3134 hash a NaN raised an InvalidOperation instead of a TypeError.
3135
Tim Petersecc6e6a2005-07-10 22:30:55 +00003136- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00003137 stream compression; add, for symmetry reasons, r:* as a synonym of r.
3138
Martin v. Löwis00a73e72005-03-04 19:40:34 +00003139- Patch #1043890: Add extractall method to tarfile.

Martin v. Löwisc72dd382005-03-04 13:50:17 +00003141- Patch #1075887: Don't require MSVC in distutils if there is nothing
3142 to build.
3143
Martin v. Löwis637431b2005-03-03 23:12:42 +00003144- Patch #1103407: Properly deal with tarfile iterators when untarring
3145 symbolic links on Windows.
3146
Tim Petersecc6e6a2005-07-10 22:30:55 +00003147- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +00003148 profile.py if available.
3149
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00003150- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
3151
Martin v. Löwisc5574e82005-03-03 10:57:37 +00003152- Patch #1117454: Remove code to special-case cookies without values
3153 in LWPCookieJar.
3154
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00003155- Patch #1117339: Add cookielib special name tests.
3156
Martin v. Löwise869eb12005-03-03 09:46:07 +00003157- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
3158
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00003159- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
3160
Martin v. Löwisdf241532005-03-03 08:17:42 +00003161- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
3162
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00003163- Patch #1104111: Alter setup.py --help and --help-commands.
3164
Martin v. Löwis4afe1542005-03-01 08:09:28 +00003165- Patch #1121234: Properly cleanup _exit and tkerror commands.
3166
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00003167- Patch #1049151: xdrlib now unpacks booleans as True or False.
3168
Raymond Hettingerbab41432005-02-05 01:31:19 +00003169- Fixed bug in a NameError bug in cookielib. Patch #1116583.
3170
Guido van Rossumd0641422005-02-03 15:01:24 +00003171- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
3172 disables recursive traversal through instance attributes, which can
3173 be exploited in various ways.
3174
Tim Peterse3547fd2005-12-16 23:13:57 +00003175- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00003176 flags on the HTTP listening socket.
3177
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00003178- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
3179 Fixed by reading the HTTP body in chunks instead of one big socket.read().
3180
Fred Drakefbdeaad2006-07-29 16:56:15 +00003181- Patches #893642, #1039083: add allow_none, encoding arguments to
3182 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00003183
Martin v. Löwis1d11de62005-01-29 13:29:23 +00003184- Bug #1110478: Revert os.environ.update to do putenv again.
3185
Thomas Hellerd6c6e222005-01-20 19:20:16 +00003186- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
3187
Martin v. Löwis22b457e2005-01-16 08:40:58 +00003188- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
3189
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003190- Enhancements to the csv module:
3191
3192 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003193 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003194 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003195 + Dialect parameter parsing has been re-implemented to improve error
3196 reporting.
3197 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3198 dictates.
3199 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003200 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003201 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003202 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3203 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003204 + reader now allows \r characters to be quoted (previously it only allowed
3205 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003206 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003207 + Dialect classes passed to the module are no longer instantiated by
3208 the module before being parsed (the former validation scheme required
3209 this, but the mechanism was unreliable).
3210 + The dialect registry now contains instances of the internal
3211 C-coded dialect type, rather than references to python objects.
3212 + the internal c-coded dialect type is now immutable.
3213 + register_dialect now accepts the same keyword dialect specifications
3214 as the reader and writer, allowing the user to register dialects
3215 without first creating a dialect class.
3216 + a configurable limit to the size of parsed fields has been added -
3217 previously, an unmatched quote character could result in the entire
3218 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003219 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003220 the parser field size limit (returning the former limit). The initial
3221 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003222 + A line_num attribute has been added to the reader object, which tracks
3223 the number of lines read from the source iterator. This is not
3224 the same as the number of records returned, as records can span
3225 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003226 + reader and writer objects were not being registered with the cyclic-GC.
3227 This has been fixed.
3228
Brett Cannone6539c42005-01-08 02:43:53 +00003229- _DummyThread objects in the threading module now delete self.__block that is
3230 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3231 lock primitives tend to be limited in number and thus should not be wasted on
3232 a _DummyThread object. Fixes bug #1089632.
3233
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003234- The imghdr module now detects Exif files.
3235
Raymond Hettinger6065d322004-12-20 23:51:53 +00003236- StringIO.truncate() now correctly adjusts the size attribute.
3237 (Bug #951915).
3238
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003239- locale.py now uses an updated locale alias table (built using
3240 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3241 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003242 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003243
Raymond Hettinger3557f422004-12-07 12:02:02 +00003244- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3245
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003246- the pickle module no longer accepts the deprecated None option in the
3247 args tuple returned by __reduce__().
3248
Brett Cannon84667c02004-12-07 03:25:18 +00003249- optparse now optionally imports gettext. This allows its use in setup.py.
3250
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003251- the pickle module no longer uses the deprecated bin parameter.
3252
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003253- the shelve module no longer uses the deprecated binary parameter.
3254
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003255- the pstats module no longer uses the deprecated ignore() method.
3256
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003257- the filecmp module no longer uses the deprecated use_statcache argument.
3258
Raymond Hettinger664347b2004-12-04 21:21:53 +00003259- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3260 extended or overridden by subclasses. Formerly, the subclassed method would
3261 be ignored by the rest of the module. (Bug #1078905).
3262
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003263- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003264 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003265
Walter Dörwald36733692004-12-22 12:50:50 +00003266- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3267 once when a size argument is given. This prevents a buffer overflow in the
3268 tokenizer with very long source lines.
3269
Barry Warsaw538561e2006-01-01 21:48:54 +00003270- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3271 immediately after creating the object, without any intervening
3272 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003273
Skip Montanaro05885812005-01-16 20:48:27 +00003274- The reconvert.quote function can now emit triple-quoted strings. The
3275 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003276
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003277- ``UserString.MutableString`` now supports negative indices in
3278 ``__setitem__`` and ``__delitem__``
3279
Greg Ward40407942005-03-05 02:53:17 +00003280- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3281 correctly.
3282
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003283- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3284 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3285 character even if the user has passed a size parameter to get a proper
3286 line ending. Remove the special handling of a "\r\n" that has been split
3287 between two lines.
3288
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003289- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3290 about illegal code points. The codec now supports PEP 293 style error
3291 handlers.
3292
Walter Dörwald78a78b02005-09-01 12:04:29 +00003293- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003294 from the input stream, so that the output is a byte string in the correct
3295 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003296
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003297- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3298 considering it exactly like a '*'.
3299
Walter Dörwald007f8df2005-10-09 19:42:27 +00003300- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3301 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003302
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003303- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3304
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003305- Patch #1413711: Certain patterns of differences were making difflib
3306 touch the recursion limit.
3307
Walter Dörwald58917a62006-03-31 15:26:22 +00003308- Bug #947906: An object oriented interface has been added to the calendar
3309 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003310 called as a script (e.g. via ``python -mcalendar``). Localized month and
3311 weekday names can be ouput (even if an exotic encoding is used) using
3312 special classes that use unicode.

3316
Neal Norwitz602d3392006-03-31 08:21:40 +00003317- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3318 by using -mieee gcc option.
3319
Martin v. Löwis86d66262006-02-17 08:40:11 +00003320- Patch #1432345: Make python compile on DragonFly.
3321
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003322- Build support for Win64-AMD64 was added.
3323
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003324- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3325
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003326- Patch #881820: look for openpty and forkpty also in libbsd.
3327
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003328- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3329 The zlib module is now builtin on Windows.
3330
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003331- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3332
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003333- Bug #1189330: configure did not correctly determine the necessary
3334 value of LINKCC if python was built with GCC 4.0.
3335
Trent Mick8321b422005-07-26 02:29:21 +00003336- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3337 vulnerability in zlib 1.2.1 and 1.2.2.
3338
Brett Cannon08cd5982005-04-24 22:26:38 +00003339- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3340 flags that change binary compatibility. Changes were also made to
3341 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003342 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003343
Bob Ippolitoed233462005-03-29 13:47:59 +00003344- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3345 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3346 no longer exists). This configure patch makes things right.
3347
Martin v. Löwise2713be2005-03-08 15:03:08 +00003348- Bug #1158607: Build with --disable-unicode again.
3349
Brett Cannon46d96232005-02-16 00:07:19 +00003350- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3351 defined. Discovered as a result of not being able to build on OS X.
3352
Brett Cannon516592f2004-12-07 00:42:59 +00003353- setup.py now uses the directories specified in LDFLAGS using the -L option
3354 and in CPPFLAGS using the -I option for adding library and include
3355 directories, respectively, for compiling extension modules against. This has
3356 led to the core being compiled using the values in CPPFLAGS. It also removes
3357 the need for the special-casing of both DarwinPorts and Fink for darwin since
3358 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3359 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3360 Fink, ``-I/opt/local/include`` for DarwinPorts).
3361
Brett Cannon43802422005-02-10 20:48:03 +00003362- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3363 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3364 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3365 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003367C API
3368-----
3369
Tim Petersc9d78aa2006-03-26 23:27:58 +00003370- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3371 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3372 is obtained via the ``PyObject_`` family, it must be released via the
3373 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3374 always been officially true, but when Python's small-object allocator was
3375 introduced, an attempt was made to cater to a few extension modules
3376 discovered at the time that obtained memory via ``PyObject_New`` but
3377 released it via ``PyMem_DEL``. It's years later, and if such code still
3378 exists it will fail now (probably with segfaults, but calling wrong
3379 low-level memory management functions can yield many symptoms).
3380
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003381- Added a C API for set and frozenset objects.
3382
Raymond Hettinger66517482004-12-03 11:45:13 +00003383- Removed PyRange_New().
3384
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003385- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3386 mapping argument now. This string is used as a mapping table. Byte values
3387 greater than the length of the string and 0xFFFE are treated as undefined
3388 mappings.
