112 was not always being done properly in some python types and extension
113 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have

115 would previously leak memory on the error path when such an allocation
116 failed have been fixed.

134
Guido van Rossumaa975432008-04-10 22:43:58 +0000135- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
136 having a self-referential tuple, which is possible from C code. Nor did
137 object's tp_str consider that a type's tp_str could do something that could
138 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
139 respectively, fixed the issues. (Backport of r58288 from trunk.)

146
Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +0000147- Issue #1477: With narrow Unicode builds, the unicode escape sequence
148 \Uxxxxxxxx did not accept values outside the Basic Multilingual Plane. This
149 affected raw unicode literals and the 'raw-unicode-escape' codec. Now
150 UTF-16 surrogates are generated in this case, like normal unicode literals
151 and the 'unicode-escape' codec.
152
Neal Norwitzb3635f92008-03-18 04:17:36 +0000153- Issue #2321: use pymalloc for unicode object string data to reduce

160 parameter but was not verifying that it was greater than zero. Values
161 less than zero will now raise a SystemError and return NULL to indicate a
162 bug in the calling C code.

Amaury Forgeot d'Arc22679b82008-08-18 19:33:42 +0000210- Issue #2234: distutils failed for some versions of the cygwin compiler. The
211 version reported by these tools does not necessarily follow the python

1199
Neal Norwitz0bcafac2006-09-11 08:51:17 +00001200- Make _PyGILState_NoteThreadState() static, it was not used anywhere
1201 outside of pystate.c and should not be necessary.
1202
Brett Cannon19d76c52006-09-09 07:18:44 +00001203- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
1204 allows calling unicode() on exceptions classes directly to succeed.
1205
Georg Brandlecab6232006-09-06 06:47:02 +00001206- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
1207 Also make sure that every exception class has __module__ set to
1208 'exceptions'.
1209
Georg Brandl37a9e572006-09-06 06:09:34 +00001210- Bug #1550983: emit better error messages for erroneous relative

1220
Neal Norwitz29a5fdb2006-09-05 02:21:38 +00001221- The return tuple from str.rpartition(sep) is (tail, sep, head) where
1222 head is the original string if sep was not found.
1223
Neal Norwitz3b3aae02006-09-05 03:56:01 +00001224- Bug #1520864: unpacking singleton tuples in list comprehensions and
1225 generator expressions (x for x, in ... ) works again. Fixing this problem
1226 required changing the .pyc magic number. This means that .pyc files
1227 generated before 2.5c2 will be regenerated.

1341
Neal Norwitz24b6f202006-09-05 04:43:56 +00001342- Fix infinite recursion when subclassing long and overriding __hash__.
1343
1344- Fix concatenation (+=) of long strings.
1345
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001346- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001347 compared equal or unequal to a string and a UnicodeDecodeError
1348 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001349
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001350 Instead, the equal (==) and unequal (!=) comparison operators will
1351 now issue a UnicodeWarning and interpret the two objects as
1352 unequal. The UnicodeWarning can be filtered as desired using
1353 the warning framework, e.g. silenced completely, turned into an
1354 exception, logged, etc.
1355
1356 Note that compare operators other than equal and unequal will still
1357 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001358
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001359- Fix segfault when doing string formatting on subclasses of long.
1360
1361- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1362 with new-style classes.
1363
1364- Fix bug related to __len__ functions returning negative values with
1365 classic classes.
1366
1367- Patch #1538606, Fix __index__() clipping. There were some problems
1368 discovered with the API and how integers that didn't fit into Py_ssize_t
1369 were handled. This patch attempts to provide enough alternatives
1370 to effectively use __index__.
1371
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001372- Bug #1536021: __hash__ may now return long int; the final hash
1373 value is obtained by invoking hash on the long int.
1374
Thomas Hellerab1049c2006-08-08 17:37:00 +00001375- Bug #1536786: buffer comparison could emit a RuntimeWarning.

Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001377- Bug #1535165: fixed a segfault in input() and raw_input() when
1378 sys.stdin is closed.
1379
Thomas Heller74d36f02006-08-04 18:17:40 +00001380- On Windows, the PyErr_Warn function is now exported from
1381 the Python dll again.
1382
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001383- Bug #1191458: tracing over for loops now produces a line event
1384 on each iteration. Fixing this problem required changing the .pyc
1385 magic number. This means that .pyc files generated before 2.5c1
1386 will be regenerated.
1387
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001388- Bug #1333982: string/number constants were inappropriately stored
1389 in the byte code and co_consts even if they were not used, ie
1390 immediately popped off the stack.
1391
Georg Brandle9462c72006-08-04 18:03:37 +00001392- Fixed a reference-counting problem in property().

1396-------
1397
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001398- Fix a bug in the ``compiler`` package that caused invalid code to be
1399 generated for generator expressions.
1400
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001401- The distutils version has been changed to 2.5.0. The change to
1402 keep it programmatically in sync with the Python version running
1403 the code (introduced in 2.5b3) has been reverted. It will continue
1404 to be maintained manually as static string literal.
1405
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001406- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001407 and this cannot be converted to the required C type, an exception is
1408 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001409 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001410
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001411- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001412 an exception.
1413
Tim Peterscbdd3502006-09-05 01:47:53 +00001414- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001415 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001416 workarounds for clocks with low resolution, to stop the code yielding
1417 duplicate UUIDs.
1418
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001419- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1420 before raising SystemExit, allowing IDLE to honor quit() and exit().
1421
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001422- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.

Georg Brandl7a1af772006-08-14 21:55:28 +00001424- Patch #1536071: trace.py should now find the full module name of a
1425 file correctly even on Windows.
1426
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001427- logging's atexit hook now runs even if the rest of the module has
1428 already been cleaned up.
1429
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001430- Bug #1112549, fix DoS attack on cgi.FieldStorage.

1433 str(exception) raised an exception.
1434
Neil Schemenauer06ded092006-08-04 16:20:30 +00001435- Fix a bug in the ``compiler`` package that caused invalid code to be

1453 uses the _as_parameter_ attribute when objects are passed to foreign
1454 function calls. The ctypes version number was changed to 1.0.1.
1455
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001456- Bug #1530559, struct.pack raises TypeError where it used to convert.
1457 Passing float arguments to struct.pack when integers are expected
1458 now triggers a DeprecationWarning.

Tim Peters4643c2f2006-08-10 22:45:34 +00001497- Bug #1069160. Internal correctness changes were made to
1498 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1499 the documentation was changed to state that the return value
1500 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001503What's New in Python 2.5 beta 3?
1504================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001505
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001506*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001507
1508Core and builtins
1509-----------------
1510
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001511- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001512 returned a long (see PEP 353).
1513
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001514- Bug #1515471: string.replace() accepts character buffers again.
1515
Neal Norwitz07aadb12006-07-30 06:55:48 +00001516- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1517 This provides the proper warning for struct.pack().
1518 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1519
Neal Norwitz0d62a062006-07-30 06:53:31 +00001520- Patch #1531113: Fix augmented assignment with yield expressions.
1521 Also fix a SystemError when trying to assign to yield expressions.
1522
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001523- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1524 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1525 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1526 excessive filesystem operations during imports.
1527
Tim Petersbc24eee2006-07-27 01:14:53 +00001528- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1529 operations on signed longs that are formally undefined by C.
1530 Unfortunately, at least one compiler now cares about that, so complicated
1531 the code to make that compiler happy again.
1532
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001533- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1534
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001535- Patch #1232023: Stop including current directory in search
1536 path on Windows.
1537
Neal Norwitze1fdb322006-07-21 05:32:28 +00001538- Fix some potential crashes found with failmalloc.
1539
Neal Norwitze7563102006-07-17 01:00:16 +00001540- Fix warnings reported by Klocwork's static analysis tool.
1541
Neal Norwitz84be93b2006-07-16 01:50:38 +00001542- Bug #1512814, Fix incorrect lineno's when code within a function
1543 had more than 255 blank lines.
1544
Georg Brandl9dceedb2006-07-12 15:31:17 +00001545- Patch #1521179: Python now accepts the standard options ``--help`` and
1546 ``--version`` as well as ``/?`` on Windows.
1547
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001548- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001549 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001550 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001551
Tim Peters112aad32006-07-19 00:03:19 +00001552- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001553 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001554 new ``sys._current_frames()`` returns a dictionary with one entry,
1555 mapping the faux "thread id" 0 to the current frame.
1556
Ronald Oussoren3075e162006-07-25 20:28:55 +00001557- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001558
Ronald Oussoren3075e162006-07-25 20:28:55 +00001559
Neal Norwitza1f10902006-07-12 07:28:29 +00001560Library
1561-------
1562
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001563- Correction of patch #1455898: In the mbcs decoder, set final=False
1564 for stream decoder, but final=True for the decode function.
1565
Georg Brandl07fec3a2006-08-01 18:49:24 +00001566- os.urandom no longer masks unrelated exceptions like SystemExit or
1567 KeyboardInterrupt.
1568
Tim Peters4643c2f2006-08-10 22:45:34 +00001569- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001570 shutil.copytree on Windows
1571
Georg Brandle34ac7c2006-07-30 11:07:23 +00001572- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1573 refers to file descriptors, not file objects.
1574
Tim Peterscbdd3502006-09-05 01:47:53 +00001575- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001576 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001577 #1513611, and probably others.
1578
Georg Brandledd9b0d2006-07-29 09:33:26 +00001579- Bug #1441397: The compiler module now recognizes module and function
1580 docstrings correctly as it did in Python 2.4.
1581
Tim Peters6f681472006-07-27 23:44:37 +00001582- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1583 lost that tests are sorted by name before being run. This rarely
1584 matters for well-written tests, but can create baffling symptoms if
1585 side effects from one test to the next affect outcomes. ``DocTestFinder``
1586 has been changed to sort the list of tests it returns.
1587
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001588- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001589 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001590
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001591- Bug #978833: Really close underlying socket in _socketobject.close.
1592
Georg Brandldb232dc2006-08-20 13:15:43 +00001593- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1594 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001595
Georg Brandlcf0c1722006-07-26 07:23:32 +00001596- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1597 to recursive calls and call it with the failing package name.
1598
Martin v. Löwis0b483032006-07-25 09:53:12 +00001599- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1600
Georg Brandlc13c34c2006-07-24 14:09:56 +00001601- Patch #1515343: Fix printing of deprecated string exceptions with a
1602 value in the traceback module.
1603
Greg Ward48fae7a2006-07-23 16:05:51 +00001604- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1605
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001606- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1607
Brett Cannoncaebe222006-07-18 04:41:36 +00001608- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1609 argument tuple. For arguments where zero is illegal, the value is forced to
1610 the minimum value that is correct. This is to support an undocumented but
1611 common way people used to fill in inconsequential information in the time
1612 tuple pre-2.4.
1613
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001614- Patch #1220874: Update the binhex module for Mach-O.
1615
Barry Warsawb110bad2006-07-21 14:51:07 +00001616- The email package has improved RFC 2231 support, specifically for
1617 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1618 (name*0=<blah>) parameter continuations. This may change the types of
1619 values returned from email.message.Message.get_param() and friends.
1620 Specifically in some cases where non-encoded continuations were used,
1621 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1622 will just return the string (since non-encoded continuations don't have
1623 charset and language parts).
1624
1625 Also, whereas % values were decoded in all parameter continuations, they are
1626 now only decoded in encoded parameter parts.
1627
Ronald Oussoren3075e162006-07-25 20:28:55 +00001628- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1629
1630- Bug #1517996: IDLE now longer shows the default Tk menu when a
1631 path browser, class browser or debugger is the frontmost window on MacOS X
1632
Barry Warsaw00decd72006-07-27 23:43:15 +00001633- Patch #1520294: Support for getset and member descriptors in types.py,
1634 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1635 of an object against these built-in types and more importantly, for getting
1636 their docstrings printed in the interactive interpreter's help() function.

1640-----------------
1641
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001642- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1643 a socket operation on a socket with a timeout, the exception will be
1644 caught correctly. Previously, the exception was not caught.
1645
Thomas Heller1393d6a2006-07-28 21:43:20 +00001646- Patch #1529514: The _ctypes extension is now compiled on more
1647 openbsd target platforms.
1648
Tim Peters9cab5932006-07-28 00:30:00 +00001649- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1650 a memory leak, affecting pickles and deep copies.
1651
Tim Petersbc24eee2006-07-27 01:14:53 +00001652- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001653 Paul Eggert.
1654
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001655- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1656
Thomas Hellerce049a02006-07-14 17:51:14 +00001657- Patch #1521817: Index range checking on ctypes arrays containing
1658 exactly one element enabled again. This allows iterating over these
1659 arrays, without the need to check the array size before.
1660
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001661- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001662 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001663 /dev/null in certain cases; this is now fixed.
1664
Thomas Heller47d7a062006-07-12 08:43:47 +00001665- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1666 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001667
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001668- Because of a misspelled preprocessor symbol, ctypes was always
1669 compiled without thread support; this is now fixed.
1670
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001671- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1672 methods now allow their database parameter to be None as the
1673 sleepycat API allows.
1674
Matt Flemingec926502006-07-28 11:27:27 +00001675- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1676 bluetooth API compared with Linux and FreeBSD.
1677
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001678Tests
1679-----
1680
1681- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1682 how long the test file should take to play. Now accepts taking 2.93 secs
1683 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1684
Georg Brandl4793aa32006-07-28 18:31:39 +00001685- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1686 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1687 run via ``regrtest.py``. Now they do.

1696
1697- PythonLauncher now works correctly when the path to the script contains
1698 characters that are treated specially by the shell (such as quotes).
1699
1700- Bug #1527397: PythonLauncher now launches scripts with the working directory
1701 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001702 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001703 expect.

Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001714- Bug #1441486: The literal representation of -(sys.maxint - 1)
1715 again evaluates to a int object, not a long.
1716
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001717- Bug #1501934: The scope of global variables that are locally assigned
1718 using augmented assignment is now correctly determined.

1724 and atof().
1725
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001726- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to

1728 the parser to take a codec from cjkcodecs again.

1731
Neal Norwitz28746ab2006-07-09 22:14:42 +00001732- On 64 bit systems, int literals that use less than 64 bits are

1736 started after line 256.
1737
Tim Peters32a83612006-07-10 21:08:24 +00001738- New function ``sys._current_frames()`` returns a dict mapping thread
1739 id to topmost thread stack frame. This is for expert use, and is
1740 especially useful for debugging application deadlocks. The functionality
1741 was previously available in Fazal Majid's ``threadframe`` extension
1742 module, but it wasn't possible to do this in a wholly threadsafe way from
1743 an extension.

1760
Thomas Woutersadd19112006-07-05 11:03:49 +00001761- string.Template() now correctly handles tuple-values. Previously,
1762 multi-value tuples would raise an exception and single-value tuples would
1763 be treated as the value they contain, instead.
1764
Martin v. Löwisede77f52006-07-03 13:01:35 +00001765- Bug #822974: Honor timeout in telnetlib.{expect,read_until}

1790
Brett Cannon53ab5b72006-06-22 16:49:14 +00001791- Bug #1510580: The 'warnings' module improperly required that a Warning
1792 category be either a types.ClassType and a subclass of Warning. The proper
1793 check is just that it is a subclass with Warning as the documentation states.
1794
Georg Brandlad29e632006-06-21 17:45:17 +00001795- The compiler module now correctly compiles the new try-except-finally
1796 statement (bug #1509132).
1797

1802
Gerhard Häring762fbd32006-07-02 17:48:30 +00001803- The sqlite3 module did cut off data from the SQLite database at the first
1804 null character before sending it to a custom converter. This has been fixed
1805 now.

1808-----------------
1809
Tim Peters112aad32006-07-19 00:03:19 +00001810- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1811 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1812 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001813
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001814- Assigning None to pointer type fields in ctypes structures possible
1815 overwrote the wrong fields, this is fixed now.
1816
1817- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1818 on non-Windows platforms.
1819
1820- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1821 integer or long, without range checking.
1822
1823- Patch #1517790: It is now possible to use custom objects in the ctypes
1824 foreign function argtypes sequence as long as they provide a from_param
1825 method, no longer is it required that the object is a ctypes type.
1826
1827- The '_ctypes' extension module now works when Python is configured
1828 with the --without-threads option.
1829
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001830- Bug #1513646: os.access on Windows now correctly determines write

1845
Tim Peters32a83612006-07-10 21:08:24 +00001846- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001847 Previously, the slight difference could cause compilation errors of the
1848 'zlib' module on systems with more than one version of zlib.
1849
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001850- The MSI compileall step was fixed to also support a TARGETDIR

1881Core and builtins
1882-----------------
1883
Georg Brandla56b9152006-06-19 06:35:54 +00001884- Patch #1507676: Error messages returned by invalid abstract object operations
1885 (such as iterating over an integer) have been improved and now include the
1886 type of the offending object to help with debugging.
1887
Brett Cannonea3912b2006-06-13 21:46:41 +00001888- Bug #992017: A classic class that defined a __coerce__() method that returned
1889 its arguments swapped would infinitely recurse and segfault the interpreter.
1890
Neal Norwitz909eb122006-06-12 02:13:21 +00001891- Fix the socket tests so they can be run concurrently.
1892
Neal Norwitzb9845e72006-06-12 02:11:18 +00001893- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001894 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001895
Brett Cannon22565aa2006-06-09 22:31:23 +00001896- Bug #532646: object.__call__() will continue looking for the __call__
1897 attribute on objects until one without one is found. This leads to recursion
1898 when you take a class and set its __call__ attribute to an instance of the
1899 class. Originally fixed for classic classes, but this fix is for new-style.
1900 Removes the infinite_rec_3 crasher.
1901
Georg Brandl24250812006-06-09 18:45:48 +00001902- The string and unicode methods startswith() and endswith() now accept
1903 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1904
Brett Cannonde3b0522006-06-08 17:00:45 +00001905- Buffer objects, at the C level, never used the char buffer
1906 implementation even when the char buffer for the wrapped object was
1907 explicitly requested (originally returned the read or write buffer).
1908 Now a TypeError is raised if the char buffer is not present but is
1909 requested.
1910
Georg Brandlddbaa662006-06-04 21:56:52 +00001911- Patch #1346214: Statements like "if 0: suite" are now again optimized
1912 away like they were in Python 2.4.
1913
Georg Brandlb7c8f542006-05-27 12:30:25 +00001914- Builtin exceptions are now full-blown new-style classes instead of
1915 instances pretending to be classes, which speeds up exception handling
1916 by about 80% in comparison to 2.5a2.
1917
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001918- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1919 Unicode 4.1.
1920
Georg Brandlf4ef1162006-05-26 18:03:31 +00001921- Patch #921466: sys.path_importer_cache is now used to cache valid and
1922 invalid file paths for the built-in import machinery which leads to
1923 fewer open calls on startup.
1924
Tim Peters696cf432006-05-24 21:10:40 +00001925- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1926 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1927 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1928 the number of input digits (it was and remains linear-time for bases
1929 2, 4, 8, 16 and 32).
1930
Tim Petersb713ec22006-05-23 18:45:30 +00001931- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1932 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1933 an integer close to ``sys.maxint``. This was repaired by patch
1934 #1335972, which also gives a nice speedup.
1935
Richard Jonescebbefc2006-05-23 18:28:17 +00001936- Patch #1337051: reduced size of frame objects.
1937
1938- PyErr_NewException now accepts a tuple of base classes as its
1939 "base" parameter.
1940
Richard Jones7c88dcc2006-05-23 10:37:38 +00001941- Patch #876206: function call speedup by retaining allocated frame
1942 objects.
1943
Georg Brandl7b90e162006-05-18 07:01:27 +00001944- Bug #1462152: file() now checks more thoroughly for invalid mode
1945 strings and removes a possible "U" before passing the mode to the
1946 C library function.
1947
Neal Norwitz1004a532006-05-15 07:17:23 +00001948- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1949
Neal Norwitz373f0a72006-05-15 07:04:36 +00001950- Bug #1487966: Fix SystemError with conditional expression in assignment
1951
Martin v. Löwis879768d2006-05-11 13:28:43 +00001952- WindowsError now has two error code attributes: errno, which carries
1953 the error values from errno.h, and winerror, which carries the error
1954 values from winerror.h. Previous versions put the winerror.h values
1955 (from GetLastError()) into the errno attribute.
1956
Martin v. Löwis77736712006-05-04 05:51:03 +00001957- Patch #1475845: Raise IndentationError for unexpected indent.
1958
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001959- Patch #1479181: split open() and file() from being aliases for each other.
1960
Tim Peters44bd9862006-06-01 13:49:23 +00001961- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1962 methods were always silently ignored by dictionaries when comparing keys.
1963 They are now passed through (except when using the C API function
1964 ``PyDict_GetItem()``, whose semantics did not change).
1965
1966- Bug #1456209: In some obscure cases it was possible for a class with a
1967 custom ``__eq__()`` method to confuse dict internals when class instances
1968 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1969 No, you don't have any code that did this ;-)

1979 buffer and actually follow its documentation.
1980
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001981- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1982
Nick Coghlanc649ec52006-05-29 12:43:05 +00001983- Patch #1478788 (modified version): The functional extension module has
1984 been renamed to _functools and a functools Python wrapper module added.
1985 This provides a home for additional function related utilities that are
1986 not specifically about functional programming. See PEP 309.
1987
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001988- Patch #1493701: performance enhancements for struct module.

1994
Andrew MacIntyre92913322006-06-13 15:04:24 +00001995- Patch #1454481: thread stack size is now tunable at runtime for thread
1996 enabled builds on Windows and systems with Posix threads support.
1997
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001998- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1999 (up to the system limit of 32K characters).
2000
2001- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
2002 As a result, these functions now raise WindowsError instead of OSError.
2003
Tim Peters7a822da2006-05-25 21:50:17 +00002004- ``time.clock()`` on Win64 should use the high-performance Windows
2005 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
2006 Windows platforms).
2007
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002008- Calling Tk_Init twice is refused if the first call failed as that
2009 may deadlock.
2010
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00002011- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
2012 accept it without potentially using an uninitialized pointer.
2013
2014- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
2015 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

2025 results. It could previously incorrectly return 0 in some cases.
2026 Fixes SF bug 1493322 (pybsddb bug 1184012).
2027
Gregory P. Smithff7d9912006-06-08 05:17:08 +00002028- bsddb: the bsddb.dbtables Modify method now raises the proper error and

Gregory P. Smith506f7b52006-06-15 08:52:32 +00002032- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00002033 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00002034 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
2035 database calls that would previously deadlock. [SF python bug #775414]
2036
Vinay Sajip28e57612006-07-01 10:45:20 +00002037- Patch #1446489: add support for the ZIP64 extensions to zipfile.

Vinay Sajip28e57612006-07-01 10:45:20 +00002050- Patch #1494750: Destroy master after deleting children in
Martin v. Löwis92733be2006-06-17 09:25:15 +00002051 Tkinter.BaseWidget.
2052

2059 mime.types file for determining MIME types.
2060
Georg Brandl2605ca82006-06-14 06:08:31 +00002061- Bug #1339007: Shelf objects now don't raise an exception in their
2062 __del__ method when initialization failed.
2063
Martin v. Löwisd8251432006-06-14 05:21:04 +00002064- Patch #1455898: The MBCS codec now supports the incremental mode for
2065 double-byte encodings.
2066
Tim Peters43898b42006-06-14 04:09:25 +00002067- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
2068 guarantee that adjacent triples in the return list always describe
2069 non-adjacent blocks. Previously, a pair of matching blocks could end
2070 up being described by multiple adjacent triples that formed a partition
2071 of the matching pair.
2072
Greg Ward0e0c9f42006-06-11 16:24:11 +00002073- Bug #1498146: fix optparse to handle Unicode strings in option help,
2074 description, and epilog.
2075
Greg Wardd1c797e2006-06-11 14:42:41 +00002076- Bug #1366250: minor optparse documentation error.
2077
Greg Ward7f547402006-06-11 00:40:49 +00002078- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
2079 clarify docs.
2080
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00002081- The wsgiref package has been added to the standard library.
2082
Nick Coghlan676725d2006-06-08 13:54:49 +00002083- The functions update_wrapper() and wraps() have been added to the functools
2084 module. These make it easier to copy relevant metadata from the original
2085 function when writing wrapper functions.
2086
Tim Petersd6a9eef2006-06-05 01:48:21 +00002087- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
2088 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00002089
Martin v. Löwis3f767792006-06-04 19:36:28 +00002090- Patch #1359618: Speed up charmap encoder by using a trie structure
2091 for lookup.
2092
Tim Petersd609b1a2006-06-02 23:22:51 +00002093- The functions in the ``pprint`` module now sort dictionaries by key
2094 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
2095 if and only if its display required more than one line, although that
2096 wasn't documented. The new behavior increases predictability; e.g.,
2097 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
2098
Georg Brandlfd9a4b12006-05-29 20:57:01 +00002099- Patch #1497027: try HTTP digest auth before basic auth in urllib2
2100 (thanks for J. J. Lee).
2101
Georg Brandl2b330372006-05-28 20:23:12 +00002102- Patch #1496206: improve urllib2 handling of passwords with respect to
2103 default HTTP and HTTPS ports.
2104
George Yoshidaf3c65de2006-05-28 16:39:09 +00002105- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
2106
Bob Ippolito7298f272006-05-23 18:43:47 +00002107- Patch #1281707: speed up gzip.readline.
2108
Georg Brandlb89316f2006-05-17 15:51:16 +00002109- Patch #1180296: Two new functions were added to the locale module:
2110 format_string() to get the effect of "format % items" but locale-aware,
2111 and currency() to format a monetary number with currency sign.
2112
Georg Brandle3a25832006-05-17 14:56:04 +00002113- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
2114 and several features added, such as speed and geometry control.
2115
Georg Brandl49c8f4c2006-05-15 19:30:35 +00002116- Patch #1488881: add support for external file objects in bz2 compressed
2117 tarfiles.
2118
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002119- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
2120 stdout arguments, making it possible to redirect input and output
2121 for remote debugging.
2122
2123- Patch #1484695: Update the tarfile module to version 0.8. This fixes
2124 a couple of issues, notably handling of long file names using the
2125 GNU LONGNAME extension.
2126
2127- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
2128 new flag when ``name`` is already the name of an option flag.
2129
2130- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
2131 package.
2132
2133- Patch #1472854: make the rlcompleter.Completer class usable on non-
2134 UNIX platforms.
2135
2136- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
2137
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00002138- Bug #1472827: correctly escape newlines and tabs in attribute values in
2139 the saxutils.XMLGenerator class.

2171

2174Core and builtins
2175-----------------
2176
Thomas Heller1b046642006-04-18 18:51:06 +00002177- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2178 by converting these apis from macros into exported functions again:
2179
2180 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2181 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2182 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
2183 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
2184 PyRun_String Py_CompileString
2185
Martin v. Löwis45294a92006-04-18 06:24:08 +00002186- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2187
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002188- All uses of PyStructSequence_InitType have been changed to initialize
2189 the type objects only once, even if the interpreter is initialized
2190 multiple times.
2191
Neal Norwitz61546162006-04-14 05:20:28 +00002192- Bug #1454485, array.array('u') could crash the interpreter. This was
2193 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2194 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2195
2196- Py_UNICODE is unsigned. It was always documented as unsigned, but
2197 due to a bug had a signed value in previous versions.
2198
Tim Peters3a5e8b12006-04-11 01:44:07 +00002199- Patch #837242: ``id()`` of any Python object always gives a positive
2200 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2201 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002202 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002203 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002204
Tim Peters3a5e8b12006-04-11 01:44:07 +00002205 def __hash__(self):
2206 return id(self) # WRONG
2207
2208 because a hash result must be a (short) Python int but it was always
2209 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002210 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002211 was always usable as a hash value before this patch. That's no longer
2212 necessarily so.
2213
2214- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002215 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002216 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002217 #1454844)
2218
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002219- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2220 involving generators that have paused outside of any ``try`` or ``with``
2221 blocks. (In 2.5a1, a paused generator that was part of a reference
2222 cycle could not be garbage collected, regardless of whether it was
2223 paused in a ``try`` or ``with`` block.)

2257 or exception is ignored).
2258
Nick Coghlanda2268f2006-04-24 04:37:15 +00002259- Fixed contextlib.nested to cope with exceptions being raised and
2260 caught inside exit handlers.
2261
Greg Wardab05edc2006-04-23 03:47:58 +00002262- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2263 hex, octal, or binary; add ``append_const`` action; keep going if
2264 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2265 added ``epilog`` for better help generation).
2266
Tim Peters21fbd572006-04-21 21:18:10 +00002267- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2268 called from a thread spawned as a side effect of importing a module.
2269
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002270- The pydoc module now supports documenting packages contained in
2271 .zip or .egg files.
2272
2273- The pkgutil module now has several new utility functions, such
2274 as ``walk_packages()`` to support working with packages that are either
2275 in the filesystem or zip files.
2276
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002277- The mailbox module can now modify and delete messages from

2279 K. Johnson for writing the code, and to the 2005 Google Summer of
2280 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002281
Tim Petersc7605f22006-04-17 21:12:33 +00002282- The ``__del__`` method of class ``local`` in module ``_threading_local``
2283 returned before accomplishing any of its intended cleanup.
2284

Nick Coghlan27ec1a72006-04-24 04:32:47 +00002337- test_cmd_line now checks operation of the -m and -c command switches
2338
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002339- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2340 it separately and by hand. It also wasn't cleaning up its changes to
2341 the current Decimal context.
2342
Thomas Woutersabd08882006-04-26 15:53:30 +00002343- regrtest.py now has a -M option to run tests that test the new limits of
2344 containers, on 64-bit architectures. Running these tests is only sensible
2345 on 64-bit machines with more than two gigabytes of memory. The argument
2346 passed is the maximum amount of memory for the tests to use.

2355-------------
2356
Tim Petersb06d28c2006-05-12 01:57:59 +00002357- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2358
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002359- PEP 343: Added Context Types section to the library reference
2360 and attempted to bring other PEP 343 related documentation into
2361 line with the implementation and/or python-dev discussions.
2362
Tim Peters8dc73d22006-04-24 02:03:16 +00002363- Bug #1337990: clarified that ``doctest`` does not support examples
2364 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002367What's New in Python 2.5 alpha 1?
2368=================================
2369
Anthony Baxterebed3f62006-04-03 15:03:44 +00002370*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002371
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002372Core and builtins
2373-----------------
2374
Nick Coghlan43832302006-04-23 17:04:07 +00002375- PEP 338: -m command line switch now delegates to runpy.run_module
2376 allowing it to support modules in packages and zipfiles
2377
Martin v. Löwisc661b882006-04-20 04:54:23 +00002378- On Windows, .DLL is not an accepted file name extension for
2379 extension modules anymore; extensions are only found if they
2380 end in .PYD.
2381
Martin v. Löwisea62d252006-04-03 10:56:49 +00002382- Bug #1421664: sys.stderr.encoding is now set to the same value as
2383 sys.stdout.encoding.
2384
Neal Norwitz92e212f2006-04-03 04:48:37 +00002385- __import__ accepts keyword arguments.
2386
Georg Brandlccadf842006-03-31 18:54:53 +00002387- Patch #1460496: round() now accepts keyword arguments.
2388
Anthony Baxter262c00a2006-03-30 10:53:17 +00002389- Fixed bug #1459029 - unicode reprs were double-escaped.
2390
Hye-Shik Changd478f342006-03-23 12:32:36 +00002391- Patch #1396919: The system scope threads are reenabled on FreeBSD
2392 5.4 and later versions.
2393
Neal Norwitze98ccf62006-03-23 05:39:47 +00002394- Bug #1115379: Compiling a Unicode string with an encoding declaration
2395 now gives a SyntaxError.
2396
Georg Brandlabd1ff82006-03-18 07:59:59 +00002397- Previously, Python code had no easy way to access the contents of a
2398 cell object. Now, a ``cell_contents`` attribute has been added
2399 (closes patch #1170323).
2400
Tim Peterscf79aac2006-03-16 01:14:46 +00002401- Patch #1123430: Python's small-object allocator now returns an arena to
2402 the system ``free()`` when all memory within an arena becomes unused
2403 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2404 freed. Some applications will see a drop in virtual memory size now,
2405 especially long-running applications that, from time to time, temporarily
2406 use a large number of small objects. Note that when Python returns an
2407 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002408 platform C library will in turn return that memory to the operating system.
2409 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002410 appears to be effective at least on Microsoft C and gcc-based systems.
2411 Thanks to Evan Jones for hard work and patience.
2412
Georg Brandl533ff6f2006-03-08 18:09:27 +00002413- Patch #1434038: property() now uses the getter's docstring if there is
2414 no "doc" argument given. This makes it possible to legitimately use
2415 property() as a decorator to produce a read-only property.
2416
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002417- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2418 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2419 of requiring an int or long in slicing and a few other contexts, enabling
2420 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2421
Neal Norwitz995acdf2006-03-07 05:01:00 +00002422- Fixed various bugs reported by Coverity's Prevent tool.
2423
Brett Cannonbf364092006-03-01 04:25:17 +00002424- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2425 new exception base class, BaseException, which has a new message attribute.
2426 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2427 Raising a string exception now raises a DeprecationWarning.
2428
Thomas Woutersfb609f42006-02-28 16:37:25 +00002429- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2430 explicitly relative, using 'from .module import name' to mean 'from the same
2431 package as this module is in. Imports without dots still default to the
2432 old relative-then-absolute, unless 'from __future__ import
2433 absolute_import' is used.
2434
Brett Cannona7446e32006-02-27 23:39:10 +00002435- Properly check if 'warnings' raises an exception (usually when a filter set
2436 to "error" is triggered) when raising a warning for raising string
2437 exceptions.
2438
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002439- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002440 The name was removed from Include/code.h.
2441
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002442- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002443
Guido van Rossum1968ad32006-02-25 22:38:04 +00002444- Patch 1433928:
2445 - The copy module now "copies" function objects (as atomic objects).
2446 - dict.__getitem__ now looks for a __missing__ hook before raising
2447 KeyError.
2448
Tim Peters84ef21c2006-02-28 20:39:06 +00002449- PEP 343: with statement implemented. Needs ``from __future__ import
2450 with_statement``. Use of 'with' as a variable will generate a warning.
2451 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002452 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002453 The following objects have __context__ methods:
2454 - The built-in file type.
2455 - The thread.LockType type.
2456 - The following types defined by the threading module:
2457 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2458 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002459
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002460- Fix the encodings package codec search function to only search
2461 inside its own package. Fixes problem reported in patch #1433198.
2462
2463 Note: Codec packages should implement and register their own
2464 codec search function. PEP 100 has the details.
2465
Tim Peters9ea89d22006-06-04 03:26:02 +00002466- PEP 353: Using ``Py_ssize_t`` as the index type.
2467
2468- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2469 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2470 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2471 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2472 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002473
Neal Norwitzfc76d632006-01-10 06:03:13 +00002474- Patch #1400181, fix unicode string formatting to not use the locale.
2475 This is how string objects work. u'%f' could use , instead of .
2476 for the decimal point. Now both strings and unicode always use periods.
2477
Neal Norwitz671b9e32006-01-09 07:07:12 +00002478- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2479 configure would break checking curses.h.
2480
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002481- Bug #959576: The pwd module is now builtin. This allows Python to be
2482 built on UNIX platforms without $HOME set.
2483
Neal Norwitzc10978f2005-12-19 06:07:16 +00002484- Bug #1072182, fix some potential problems if characters are signed.
2485
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002486- Bug #889500, fix line number on SyntaxWarning for global declarations.
2487
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002488- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2489
Neal Norwitze7214a12005-12-18 05:03:17 +00002490- Support for converting hex strings to floats no longer works.
2491 This was not portable. float('0x3') now raises a ValueError.
2492
Barry Warsaw2a38a862005-12-18 01:27:35 +00002493- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002494 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002495 is now displayed in interactive prompt banner.
2496
Georg Brandlfa166682005-12-17 21:45:17 +00002497- Implementation of PEP 341 - Unification of try/except and try/finally.
2498 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002499 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002500
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002501- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2502 now encodes backslash correctly.
2503
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002504- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2505
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002506- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002507 and long longs.
2508
Neal Norwitz67715f02005-11-09 06:59:35 +00002509- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002510 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002511 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002512
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002513- Replaced most Unicode charmap codecs with new ones using the
2514 new Unicode translate string feature in the builtin charmap
2515 codec; the codecs were created from the mapping tables available
2516 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2517 encodings now include a mapping for the Apple logo)
2518
Tim Peterse3547fd2005-12-16 23:13:57 +00002519- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002520
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002521- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002522
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002523- A new AST parser implementation was completed. The abstract
2524 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002525 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002526
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002527- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002528 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2529
Neal Norwitz708e51a2005-10-03 04:48:15 +00002530- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2531
Neal Norwitz11bd1192005-10-03 00:54:56 +00002532- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2533 Provide a warning when a directory is passed on the command line.
2534
Neal Norwitz40d37812005-10-02 01:48:49 +00002535- Fix segfault with invalid coding.
2536
2537- SF bug #772896: unknown encoding results in MemoryError.
2538
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002539- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002540 supported a __len__() method which evaluated to False when the iterator
2541 was empty.
2542
Guido van Rossum630db602005-09-20 18:49:54 +00002543- On 64-bit platforms, when __len__() returns a value that cannot be
2544 represented as a C int, raise OverflowError.
2545
Skip Montanarof8948ca2005-09-19 03:54:46 +00002546- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002547 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002548
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002549- SF bug #893549: parsing keyword arguments was broken with a few format
2550 codes.
2551
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002552- Changes donated by Elemental Security to make it work on AIX 5.3
2553 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2554 bug #105470: test_pwd fails on 64bit system (Opteron).
2555
Guido van Rossum539c6622005-09-14 17:49:54 +00002556- Changes donated by Elemental Security to make it work on HP-UX 11 on
2557 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2558
Georg Brandl4550b8d2005-08-26 06:43:52 +00002559- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002560 (fixes bug #1119418).
2561
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002562- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2563
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002564- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2565 exceptions that cause a function to exit.
2566
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002567- The implementation of set() and frozenset() was revised to use its
2568 own internal data structure. Memory consumption is reduced by 1/3
2569 and there are modest speed-ups as well. The API is unchanged.
2570
Tim Petersde7990b2005-07-17 23:45:23 +00002571- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2572
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002573- SF bug #1229429: PyObject_CallMethod failed to decrement some
2574 reference counts in some error exit cases.
2575
Tim Petersecc6e6a2005-07-10 22:30:55 +00002576- SF bug #1185883: Python's small-object memory allocator took over
2577 a block managed by the platform C library whenever a realloc specified
2578 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002579 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002580 portable way to copy data from the C-managed block into Python's
2581 small-object space without risking a memory fault. Python's small-object
2582 realloc now leaves such blocks under the control of the platform C
2583 realloc.
2584
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002585- SF bug #1232517: An overflow error was not detected properly when
2586 attempting to convert a large float to an int in os.utime().
2587
Raymond Hettinger3296e692005-06-29 23:29:56 +00002588- SF bug #1224347: hex longs now print with lowercase letters just
2589 like their int counterparts.
2590
Michael W. Hudson188d4362005-06-20 16:52:57 +00002591- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2592 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2593 interpreter states; back out that fix and do a better job (see
2594 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2595 for a longer write-up of the problem).
2596
Michael W. Hudsondf888462005-06-03 14:41:55 +00002597- SF patch #1180995: marshal now uses a binary format by default when
2598 serializing floats.
2599
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002600- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2601 the routines that promise to produce IEEE 754 binary representations
2602 of floats now simply copy bytes around.
2603
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002604- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2605 278.

Brett Cannonc3647ac2005-04-26 03:45:26 +00002607- patch #1109424: int, long, float, complex, and unicode now check for the
2608 proper magic slot for type conversions when subclassed. Previously the
2609 magic slot was ignored during conversion. Semantics now match the way
2610 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002611 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002612 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002613 Thanks Walter D�rwald.

Barry Warsawc8d907c2005-04-19 23:43:40 +00002615- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2616 NULL, now raise an AttributeError when attempting to set or delete the
2617 attribute. Previously a TypeError was raised, but this was inconsistent
2618 with the equivalent pure-Python implementation.
2619
Michael W. Hudson774479c2005-04-18 08:46:17 +00002620- It is now safe to call PyGILState_Release() before
2621 PyEval_InitThreads() (note that if there is reason to believe there
2622 are multiple threads around you still must call PyEval_InitThreads()
2623 before using the Python API; this fix is for extension modules that
2624 have no way of knowing if Python is multi-threaded yet).
2625
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002626- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2627 disabled caused a crash.
2628
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002629- Bug #1165306: instancemethod_new allowed the creation of a method
2630 with im_class == im_self == NULL, which caused a crash when called.
2631
Tim Petersecc6e6a2005-07-10 22:30:55 +00002632- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002633 fixes the crash seen in bug #1165761
2634
Raymond Hettinger96229b12005-03-11 06:49:40 +00002635- Added two new builtins, any() and all().
2636
Brett Cannon409d8f22005-03-05 06:47:57 +00002637- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002638 (e.g., ``class C(): pass`` is no longer a syntax error).
2639 Patch #1176012 added support to the 'parser' module and 'compiler' package
2640 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002641
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002642- Patch #1115086: Support PY_LONGLONG in structmember.
2643
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002644- Bug #1155938: new style classes did not check that __init__() was
2645 returning None.
2646
Tim Petersecc6e6a2005-07-10 22:30:55 +00002647- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002648 ('\') with a specific error message.
2649
Martin v. Löwisff232d72005-03-03 09:24:38 +00002650- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2651
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002652- Bug #1124295: the __name__ attribute of file objects was
2653 inadvertently made inaccessible in restricted mode.
2654
Tim Petersecc6e6a2005-07-10 22:30:55 +00002655- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002656 an ferror() call.
2657
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002658- min() and max() now support key= arguments with the same meaning as in
2659 list.sort().
2660
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002661- The peephole optimizer now performs simple constant folding in expressions:
2662 (2+3) --> (5).
2663
Raymond Hettingera422c342005-01-11 03:03:27 +00002664- set and frozenset objects can now be marshalled. SF #1098985.
2665
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002666- Bug #1077106: Poor argument checking could cause memory corruption
2667 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002668
Jeremy Hyltonab630502005-02-04 18:44:06 +00002669- The parser did not complain about future statements in illegal
2670 positions. It once again reports a syntax error if a future
2671 statement occurs after anything other than a doc string.
2672
Neil Schemenauercf52c072005-08-12 17:34:58 +00002673- Change the %s format specifier for str objects so that it returns a
2674 unicode instance if the argument is not an instance of basestring and
2675 calling __str__ on the argument returns a unicode instance.
2676
Tim Petersf4e69282006-02-27 17:15:31 +00002677- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2678 current thread state when the auto-GIL-state machinery knows about
2679 it (since the thread state is being deleted, continuing to remember it
2680 can't help, but can hurt if another thread happens to get created with
2681 the same thread id).

Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002873- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2874 been renamed to have only a single underscore prefix. This was done to
2875 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002876
Nick Coghlan43832302006-04-23 17:04:07 +00002877- PEP 338: new module runpy defines a run_module function to support
2878 executing modules which provide access to source code or a code object
2879 via the PEP 302 import mechanisms.
2880
Anthony Baxter93f5b932006-04-03 08:05:07 +00002881- The email module's parsedate_tz function now sets the daylight savings
2882 flag to -1 (unknown) since it can't tell from the date whether it should
2883 be set.
2884

2886 now sport attributes that provide access to the parts of the result.
2887

2889 in attribute values.
2890
Anthony Baxterc51ee692006-04-01 00:57:31 +00002891- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002892 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002893 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002894 module will not be built.
2895
Tim Petersc17976e2006-04-01 00:26:53 +00002896- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2897 aren't officially supported here, and trying to use them will probably
2898 raise an exception some day. But dicts have been allowed, and "mostly
2899 worked", so support for them won't go away without warning.
2900
Georg Brandl338ef7d2006-03-31 18:42:16 +00002901- Bug #1445068: getpass.getpass() can now be given an explicit stream
2902 argument to specify where to write the prompt.
2903
Georg Brandl22ec80b2006-03-31 18:25:44 +00002904- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2910 key to be used for signing the uploaded code.
2911
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002912- Queue.Queue objects now support .task_done() and .join() methods
2913 to make it easier to monitor when daemon threads have completed
2914 processing all enqueued tasks. Patch #1455676.
2915
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002916- popen2.Popen objects now preserve the command in a .cmd attribute.
2917
Thomas Hellerc61c0492006-03-22 10:09:27 +00002918- Added the ctypes ffi package.
2919
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002920- email 4.0 package now integrated. This is largely the same as the email 3.0
2921 package that was included in Python 2.3, except that PEP 8 module names are
2922 now used (e.g. mail.message instead of email.Message). The MIME classes
2923 have been moved to a subpackage (e.g. email.mime.text instead of
2924 email.MIMEText). The old names are still supported for now. Several
2925 deprecated Message methods have been removed and lots of bugs have been
2926 fixed. More details can be found in the email package documentation.
2927
Walter Dörwald40108c92006-03-27 08:15:44 +00002928- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2929 (a subclass of tuple) that provides incremental decoders and encoders
2930 (a way to use stateful codecs without the stream API). Python functions
2931 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2932 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2933 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002934
Walter Dörwald067db482006-03-15 22:17:27 +00002935- Patch #1359365: Calling next() on a closed StringIO.String object raises
2936 a ValueError instead of a StopIteration now (like file and cString.String do).
2937 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2938 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002939
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002940- A regrtest option -w was added to re-run failed tests in verbose mode.

2943 interpreter to exit.
2944
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002945- The function get_count() has been added to the gc module, and gc.collect()

2952 and helpful context managers nested() and closing().
2953

Tim Peterse3547fd2005-12-16 23:13:57 +00003012 SHA1, 224, 256, 384, and 512. Note that recent developments make the
3013 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
3014 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
3015 Ronald L. Rivest offered this advice for Python:
3016
3017 "The consensus of researchers in this area (at least as
3018 expressed at the NIST Hash Function Workshop 10/31/05),
3019 is that SHA-256 is a good choice for the time being, but
3020 that research should continue, and other alternatives may
3021 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00003022
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00003023- Added a subset of Fredrik Lundh's ElementTree package. Available

3134 files to PyPI.
3135
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00003136- distutils.commands.register now encodes the data as UTF-8 before posting
3137 them to PyPI.
3138
Raymond Hettinger267b8682005-03-27 10:47:39 +00003139- decimal operator and comparison methods now return NotImplemented
3140 instead of raising a TypeError when interacting with other types. This
3141 allows other classes to implement __radd__ style methods and have them
3142 work as expected.
3143
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00003144- Bug #1163325: Decimal infinities failed to hash. Attempting to
3145 hash a NaN raised an InvalidOperation instead of a TypeError.
3146
Tim Petersecc6e6a2005-07-10 22:30:55 +00003147- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00003148 stream compression; add, for symmetry reasons, r:* as a synonym of r.
3149
Martin v. Löwis00a73e72005-03-04 19:40:34 +00003150- Patch #1043890: Add extractall method to tarfile.

Martin v. Löwisc72dd382005-03-04 13:50:17 +00003152- Patch #1075887: Don't require MSVC in distutils if there is nothing
3153 to build.
3154
Martin v. Löwis637431b2005-03-03 23:12:42 +00003155- Patch #1103407: Properly deal with tarfile iterators when untarring
3156 symbolic links on Windows.
3157
Tim Petersecc6e6a2005-07-10 22:30:55 +00003158- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +00003159 profile.py if available.
3160
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00003161- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
3162
Martin v. Löwisc5574e82005-03-03 10:57:37 +00003163- Patch #1117454: Remove code to special-case cookies without values
3164 in LWPCookieJar.
3165
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00003166- Patch #1117339: Add cookielib special name tests.

3169
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00003170- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
3171
Martin v. Löwisdf241532005-03-03 08:17:42 +00003172- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
3173
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00003174- Patch #1104111: Alter setup.py --help and --help-commands.
3175
Martin v. Löwis4afe1542005-03-01 08:09:28 +00003176- Patch #1121234: Properly cleanup _exit and tkerror commands.
3177
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00003178- Patch #1049151: xdrlib now unpacks booleans as True or False.
3179
Raymond Hettingerbab41432005-02-05 01:31:19 +00003180- Fixed bug in a NameError bug in cookielib. Patch #1116583.
3181
Guido van Rossumd0641422005-02-03 15:01:24 +00003182- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
3183 disables recursive traversal through instance attributes, which can
3184 be exploited in various ways.
3185
Tim Peterse3547fd2005-12-16 23:13:57 +00003186- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00003187 flags on the HTTP listening socket.
3188
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00003189- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
3190 Fixed by reading the HTTP body in chunks instead of one big socket.read().
3191
Fred Drakefbdeaad2006-07-29 16:56:15 +00003192- Patches #893642, #1039083: add allow_none, encoding arguments to
3193 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00003194
Martin v. Löwis1d11de62005-01-29 13:29:23 +00003195- Bug #1110478: Revert os.environ.update to do putenv again.
3196
Thomas Hellerd6c6e222005-01-20 19:20:16 +00003197- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
3198
Martin v. Löwis22b457e2005-01-16 08:40:58 +00003199- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
3200
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003201- Enhancements to the csv module:
3202
3203 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003204 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003205 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003206 + Dialect parameter parsing has been re-implemented to improve error
3207 reporting.
3208 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3209 dictates.
3210 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003211 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003212 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003213 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3214 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003215 + reader now allows \r characters to be quoted (previously it only allowed
3216 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003217 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003218 + Dialect classes passed to the module are no longer instantiated by
3219 the module before being parsed (the former validation scheme required
3220 this, but the mechanism was unreliable).
3221 + The dialect registry now contains instances of the internal
3222 C-coded dialect type, rather than references to python objects.
3223 + the internal c-coded dialect type is now immutable.
3224 + register_dialect now accepts the same keyword dialect specifications
3225 as the reader and writer, allowing the user to register dialects
3226 without first creating a dialect class.
3227 + a configurable limit to the size of parsed fields has been added -
3228 previously, an unmatched quote character could result in the entire
3229 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003230 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003231 the parser field size limit (returning the former limit). The initial
3232 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003233 + A line_num attribute has been added to the reader object, which tracks
3234 the number of lines read from the source iterator. This is not
3235 the same as the number of records returned, as records can span
3236 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003237 + reader and writer objects were not being registered with the cyclic-GC.
3238 This has been fixed.
3239
Brett Cannone6539c42005-01-08 02:43:53 +00003240- _DummyThread objects in the threading module now delete self.__block that is
3241 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3242 lock primitives tend to be limited in number and thus should not be wasted on
3243 a _DummyThread object. Fixes bug #1089632.
3244
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003245- The imghdr module now detects Exif files.
3246
Raymond Hettinger6065d322004-12-20 23:51:53 +00003247- StringIO.truncate() now correctly adjusts the size attribute.
3248 (Bug #951915).
3249
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003250- locale.py now uses an updated locale alias table (built using
3251 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3252 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003253 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003254
Raymond Hettinger3557f422004-12-07 12:02:02 +00003255- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3256
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003257- the pickle module no longer accepts the deprecated None option in the
3258 args tuple returned by __reduce__().
3259
Brett Cannon84667c02004-12-07 03:25:18 +00003260- optparse now optionally imports gettext. This allows its use in setup.py.
3261
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003262- the pickle module no longer uses the deprecated bin parameter.
3263
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003264- the shelve module no longer uses the deprecated binary parameter.
3265
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003266- the pstats module no longer uses the deprecated ignore() method.
3267
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003268- the filecmp module no longer uses the deprecated use_statcache argument.
3269
Raymond Hettinger664347b2004-12-04 21:21:53 +00003270- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3271 extended or overridden by subclasses. Formerly, the subclassed method would
3272 be ignored by the rest of the module. (Bug #1078905).
3273
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003274- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003275 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003276
Walter Dörwald36733692004-12-22 12:50:50 +00003277- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3278 once when a size argument is given. This prevents a buffer overflow in the
3279 tokenizer with very long source lines.
3280
Barry Warsaw538561e2006-01-01 21:48:54 +00003281- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3282 immediately after creating the object, without any intervening
3283 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003284
Skip Montanaro05885812005-01-16 20:48:27 +00003285- The reconvert.quote function can now emit triple-quoted strings. The
3286 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003287
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003288- ``UserString.MutableString`` now supports negative indices in
3289 ``__setitem__`` and ``__delitem__``
3290
Greg Ward40407942005-03-05 02:53:17 +00003291- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3292 correctly.
3293
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003294- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3295 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3296 character even if the user has passed a size parameter to get a proper
3297 line ending. Remove the special handling of a "\r\n" that has been split
3298 between two lines.
3299
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003300- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3301 about illegal code points. The codec now supports PEP 293 style error
3302 handlers.
3303
Walter Dörwald78a78b02005-09-01 12:04:29 +00003304- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003305 from the input stream, so that the output is a byte string in the correct
3306 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003307
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003308- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3309 considering it exactly like a '*'.
3310
Walter Dörwald007f8df2005-10-09 19:42:27 +00003311- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3312 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003313
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003314- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3315
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003316- Patch #1413711: Certain patterns of differences were making difflib
3317 touch the recursion limit.
3318
Walter Dörwald58917a62006-03-31 15:26:22 +00003319- Bug #947906: An object oriented interface has been added to the calendar
3320 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003321 called as a script (e.g. via ``python -mcalendar``). Localized month and
3322 weekday names can be ouput (even if an exotic encoding is used) using
3323 special classes that use unicode.

Neal Norwitz602d3392006-03-31 08:21:40 +00003328- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3329 by using -mieee gcc option.
3330
Martin v. Löwis86d66262006-02-17 08:40:11 +00003331- Patch #1432345: Make python compile on DragonFly.
3332
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003333- Build support for Win64-AMD64 was added.
3334
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003335- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3336
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003337- Patch #881820: look for openpty and forkpty also in libbsd.
3338
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003339- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3340 The zlib module is now builtin on Windows.
3341
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003342- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3343
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003344- Bug #1189330: configure did not correctly determine the necessary
3345 value of LINKCC if python was built with GCC 4.0.
3346
Trent Mick8321b422005-07-26 02:29:21 +00003347- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3348 vulnerability in zlib 1.2.1 and 1.2.2.
3349
Brett Cannon08cd5982005-04-24 22:26:38 +00003350- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3351 flags that change binary compatibility. Changes were also made to
3352 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003353 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003354
Bob Ippolitoed233462005-03-29 13:47:59 +00003355- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3356 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3357 no longer exists). This configure patch makes things right.
3358
Martin v. Löwise2713be2005-03-08 15:03:08 +00003359- Bug #1158607: Build with --disable-unicode again.
3360
Brett Cannon46d96232005-02-16 00:07:19 +00003361- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3362 defined. Discovered as a result of not being able to build on OS X.
3363
Brett Cannon516592f2004-12-07 00:42:59 +00003364- setup.py now uses the directories specified in LDFLAGS using the -L option
3365 and in CPPFLAGS using the -I option for adding library and include
3366 directories, respectively, for compiling extension modules against. This has
3367 led to the core being compiled using the values in CPPFLAGS. It also removes
3368 the need for the special-casing of both DarwinPorts and Fink for darwin since
3369 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3370 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3371 Fink, ``-I/opt/local/include`` for DarwinPorts).
3372
Brett Cannon43802422005-02-10 20:48:03 +00003373- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3374 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3375 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3376 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003378C API
3379-----
3380
Tim Petersc9d78aa2006-03-26 23:27:58 +00003381- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3382 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3383 is obtained via the ``PyObject_`` family, it must be released via the
3384 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3385 always been officially true, but when Python's small-object allocator was
3386 introduced, an attempt was made to cater to a few extension modules
3387 discovered at the time that obtained memory via ``PyObject_New`` but
3388 released it via ``PyMem_DEL``. It's years later, and if such code still
3389 exists it will fail now (probably with segfaults, but calling wrong
3390 low-level memory management functions can yield many symptoms).
3391
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003392- Added a C API for set and frozenset objects.
3393
Raymond Hettinger66517482004-12-03 11:45:13 +00003394- Removed PyRange_New().
3395
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003396- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3397 mapping argument now. This string is used as a mapping table. Byte values
3398 greater than the length of the string and 0xFFFE are treated as undefined
3399 mappings.
