Amaury Forgeot d'Arcb50f9922008-09-26 22:46:01 +000046- Issue #3967: Fixed a crash in the count() and find() methods of string-like
47 objects, when the "start" parameter is a huge value.

75 another file in sys.stdout.
76
Amaury Forgeot d'Arcb15bdf72008-07-01 20:59:49 +000077- Issue #3088: Corrected a race condition in classes derived from

83
Guido van Rossumaa975432008-04-10 22:43:58 +000084- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
85 having a self-referential tuple, which is possible from C code. Nor did
86 object's tp_str consider that a type's tp_str could do something that could
87 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
88 respectively, fixed the issues. (Backport of r58288 from trunk.)

94 reference on the outer class name.
95
Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +000096- Issue #1477: With narrow Unicode builds, the unicode escape sequence
97 \Uxxxxxxxx did not accept values outside the Basic Multilingual Plane. This
98 affected raw unicode literals and the 'raw-unicode-escape' codec. Now
99 UTF-16 surrogates are generated in this case, like normal unicode literals
100 and the 'unicode-escape' codec.
101
Neal Norwitzb3635f92008-03-18 04:17:36 +0000102- Issue #2321: use pymalloc for unicode object string data to reduce
103 memory usage in some circumstances.
Andrew M. Kuchlingbe0adfc2008-02-23 17:18:19 +0000104
Sean Reifscheider4af861c2008-03-20 17:39:31 +0000105- Issue #2238: Some syntax errors in *args and **kwargs expressions could give

109 parameter but was not verifying that it was greater than zero. Values
110 less than zero will now raise a SystemError and return NULL to indicate a
111 bug in the calling C code.
112
Gregory P. Smith9aa040d2008-06-02 00:07:25 +0000113- Issue #2588, #2589: Fix potential integer underflow and overflow
114 conditions in the PyOS_vsnprintf C API function.
115
Gregory P. Smithcae7f882008-09-07 06:44:12 +0000116- Issue #1204: The configure script now tests for additional libraries
117 that may be required when linking against readline. This fixes issues
118 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
Georg Brandld9f1da02008-03-29 01:50:46 +0000119
Gregory P. Smitha7a94a02008-09-22 00:22:44 +0000120- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
121 library targets in the Makefile.

158
Amaury Forgeot d'Arc22679b82008-08-18 19:33:42 +0000159- Issue #2234: distutils failed for some versions of the cygwin compiler. The
160 version reported by these tools does not necessarily follow the python
161 version numbering scheme, so the module is less strict when parsing it.
162
Hirokazu Yamamoto1d63a452008-08-17 09:49:10 +0000163- Issue #2222: Fixed reference leak when occured os.rename()

1288Core and builtins
1289-----------------
1290
Neal Norwitz24b6f202006-09-05 04:43:56 +00001291- Fix infinite recursion when subclassing long and overriding __hash__.
1292
1293- Fix concatenation (+=) of long strings.
1294
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001295- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001296 compared equal or unequal to a string and a UnicodeDecodeError
1297 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001298
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001299 Instead, the equal (==) and unequal (!=) comparison operators will
1300 now issue a UnicodeWarning and interpret the two objects as
1301 unequal. The UnicodeWarning can be filtered as desired using
1302 the warning framework, e.g. silenced completely, turned into an
1303 exception, logged, etc.
1304
1305 Note that compare operators other than equal and unequal will still
1306 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001307
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001308- Fix segfault when doing string formatting on subclasses of long.
1309
1310- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1311 with new-style classes.
1312
1313- Fix bug related to __len__ functions returning negative values with
1314 classic classes.
1315
1316- Patch #1538606, Fix __index__() clipping. There were some problems
1317 discovered with the API and how integers that didn't fit into Py_ssize_t
1318 were handled. This patch attempts to provide enough alternatives
1319 to effectively use __index__.
1320
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001321- Bug #1536021: __hash__ may now return long int; the final hash
1322 value is obtained by invoking hash on the long int.
1323
Thomas Hellerab1049c2006-08-08 17:37:00 +00001324- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1325
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001326- Bug #1535165: fixed a segfault in input() and raw_input() when
1327 sys.stdin is closed.
1328
Thomas Heller74d36f02006-08-04 18:17:40 +00001329- On Windows, the PyErr_Warn function is now exported from
1330 the Python dll again.
1331
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001332- Bug #1191458: tracing over for loops now produces a line event
1333 on each iteration. Fixing this problem required changing the .pyc
1334 magic number. This means that .pyc files generated before 2.5c1
1335 will be regenerated.
1336
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001337- Bug #1333982: string/number constants were inappropriately stored
1338 in the byte code and co_consts even if they were not used, ie
1339 immediately popped off the stack.
1340
Georg Brandle9462c72006-08-04 18:03:37 +00001341- Fixed a reference-counting problem in property().

1344Library
1345-------
1346
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001347- Fix a bug in the ``compiler`` package that caused invalid code to be
1348 generated for generator expressions.
1349
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001350- The distutils version has been changed to 2.5.0. The change to
1351 keep it programmatically in sync with the Python version running
1352 the code (introduced in 2.5b3) has been reverted. It will continue
1353 to be maintained manually as static string literal.
1354
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001355- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001356 and this cannot be converted to the required C type, an exception is
1357 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001358 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001359
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001360- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001361 an exception.
1362
Tim Peterscbdd3502006-09-05 01:47:53 +00001363- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001364 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001365 workarounds for clocks with low resolution, to stop the code yielding
1366 duplicate UUIDs.
1367
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001368- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1369 before raising SystemExit, allowing IDLE to honor quit() and exit().
1370
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001371- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1372
Georg Brandl7a1af772006-08-14 21:55:28 +00001373- Patch #1536071: trace.py should now find the full module name of a
1374 file correctly even on Windows.
1375
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001376- logging's atexit hook now runs even if the rest of the module has
1377 already been cleaned up.
1378
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001379- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001380
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001381- Bug #1531405, format_exception no longer raises an exception if
1382 str(exception) raised an exception.
1383
Neil Schemenauer06ded092006-08-04 16:20:30 +00001384- Fix a bug in the ``compiler`` package that caused invalid code to be
1385 generated for nested functions.

Thomas Heller86720042006-08-14 11:17:48 +00001401- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1402 uses the _as_parameter_ attribute when objects are passed to foreign
1403 function calls. The ctypes version number was changed to 1.0.1.
1404
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001405- Bug #1530559, struct.pack raises TypeError where it used to convert.
1406 Passing float arguments to struct.pack when integers are expected
1407 now triggers a DeprecationWarning.

1457Core and builtins
1458-----------------
1459
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001460- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001461 returned a long (see PEP 353).
1462
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001463- Bug #1515471: string.replace() accepts character buffers again.
1464
Neal Norwitz07aadb12006-07-30 06:55:48 +00001465- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1466 This provides the proper warning for struct.pack().
1467 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1468
Neal Norwitz0d62a062006-07-30 06:53:31 +00001469- Patch #1531113: Fix augmented assignment with yield expressions.
1470 Also fix a SystemError when trying to assign to yield expressions.
1471
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001472- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1473 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1474 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1475 excessive filesystem operations during imports.
1476
Tim Petersbc24eee2006-07-27 01:14:53 +00001477- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1478 operations on signed longs that are formally undefined by C.
1479 Unfortunately, at least one compiler now cares about that, so complicated
1480 the code to make that compiler happy again.
1481
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001482- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1483
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001484- Patch #1232023: Stop including current directory in search
1485 path on Windows.
1486
Neal Norwitze1fdb322006-07-21 05:32:28 +00001487- Fix some potential crashes found with failmalloc.
1488
Neal Norwitze7563102006-07-17 01:00:16 +00001489- Fix warnings reported by Klocwork's static analysis tool.
1490
Neal Norwitz84be93b2006-07-16 01:50:38 +00001491- Bug #1512814, Fix incorrect lineno's when code within a function
1492 had more than 255 blank lines.
1493
Georg Brandl9dceedb2006-07-12 15:31:17 +00001494- Patch #1521179: Python now accepts the standard options ``--help`` and
1495 ``--version`` as well as ``/?`` on Windows.
1496
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001497- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001498 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001499 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001500
Tim Peters112aad32006-07-19 00:03:19 +00001501- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001502 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001503 new ``sys._current_frames()`` returns a dictionary with one entry,
1504 mapping the faux "thread id" 0 to the current frame.
1505
Ronald Oussoren3075e162006-07-25 20:28:55 +00001506- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001507

1510-------
1511
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001512- Correction of patch #1455898: In the mbcs decoder, set final=False
1513 for stream decoder, but final=True for the decode function.
1514
Georg Brandl07fec3a2006-08-01 18:49:24 +00001515- os.urandom no longer masks unrelated exceptions like SystemExit or
1516 KeyboardInterrupt.
1517
Tim Peters4643c2f2006-08-10 22:45:34 +00001518- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001519 shutil.copytree on Windows
1520
Georg Brandle34ac7c2006-07-30 11:07:23 +00001521- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1522 refers to file descriptors, not file objects.
1523
Tim Peterscbdd3502006-09-05 01:47:53 +00001524- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001525 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001526 #1513611, and probably others.
1527
Georg Brandledd9b0d2006-07-29 09:33:26 +00001528- Bug #1441397: The compiler module now recognizes module and function
1529 docstrings correctly as it did in Python 2.4.
1530
Tim Peters6f681472006-07-27 23:44:37 +00001531- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1532 lost that tests are sorted by name before being run. This rarely
1533 matters for well-written tests, but can create baffling symptoms if
1534 side effects from one test to the next affect outcomes. ``DocTestFinder``
1535 has been changed to sort the list of tests it returns.
1536
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001537- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001538 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001539
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001540- Bug #978833: Really close underlying socket in _socketobject.close.
1541
Georg Brandldb232dc2006-08-20 13:15:43 +00001542- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1543 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001544
Georg Brandlcf0c1722006-07-26 07:23:32 +00001545- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1546 to recursive calls and call it with the failing package name.
1547
Martin v. Löwis0b483032006-07-25 09:53:12 +00001548- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1549
Georg Brandlc13c34c2006-07-24 14:09:56 +00001550- Patch #1515343: Fix printing of deprecated string exceptions with a
1551 value in the traceback module.
1552
Greg Ward48fae7a2006-07-23 16:05:51 +00001553- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1554
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001555- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1556
Brett Cannoncaebe222006-07-18 04:41:36 +00001557- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1558 argument tuple. For arguments where zero is illegal, the value is forced to
1559 the minimum value that is correct. This is to support an undocumented but
1560 common way people used to fill in inconsequential information in the time
1561 tuple pre-2.4.
1562
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001563- Patch #1220874: Update the binhex module for Mach-O.
1564
Barry Warsawb110bad2006-07-21 14:51:07 +00001565- The email package has improved RFC 2231 support, specifically for
1566 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1567 (name*0=<blah>) parameter continuations. This may change the types of
1568 values returned from email.message.Message.get_param() and friends.
1569 Specifically in some cases where non-encoded continuations were used,
1570 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1571 will just return the string (since non-encoded continuations don't have
1572 charset and language parts).
1573
1574 Also, whereas % values were decoded in all parameter continuations, they are
1575 now only decoded in encoded parameter parts.
1576
Ronald Oussoren3075e162006-07-25 20:28:55 +00001577- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1578
1579- Bug #1517996: IDLE now longer shows the default Tk menu when a
1580 path browser, class browser or debugger is the frontmost window on MacOS X
1581
Barry Warsaw00decd72006-07-27 23:43:15 +00001582- Patch #1520294: Support for getset and member descriptors in types.py,
1583 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1584 of an object against these built-in types and more importantly, for getting
1585 their docstrings printed in the interactive interpreter's help() function.

1589-----------------
1590
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001591- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1592 a socket operation on a socket with a timeout, the exception will be
1593 caught correctly. Previously, the exception was not caught.
1594
Thomas Heller1393d6a2006-07-28 21:43:20 +00001595- Patch #1529514: The _ctypes extension is now compiled on more
1596 openbsd target platforms.
1597
Tim Peters9cab5932006-07-28 00:30:00 +00001598- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1599 a memory leak, affecting pickles and deep copies.
1600
Tim Petersbc24eee2006-07-27 01:14:53 +00001601- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001602 Paul Eggert.
1603
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001604- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1605
Thomas Hellerce049a02006-07-14 17:51:14 +00001606- Patch #1521817: Index range checking on ctypes arrays containing
1607 exactly one element enabled again. This allows iterating over these
1608 arrays, without the need to check the array size before.
1609
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001610- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001611 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001612 /dev/null in certain cases; this is now fixed.
1613
Thomas Heller47d7a062006-07-12 08:43:47 +00001614- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1615 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001616
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001617- Because of a misspelled preprocessor symbol, ctypes was always
1618 compiled without thread support; this is now fixed.
1619
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001620- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1621 methods now allow their database parameter to be None as the
1622 sleepycat API allows.
1623
Matt Flemingec926502006-07-28 11:27:27 +00001624- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1625 bluetooth API compared with Linux and FreeBSD.
1626
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001627Tests
1628-----
1629
1630- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1631 how long the test file should take to play. Now accepts taking 2.93 secs
1632 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1633
Georg Brandl4793aa32006-07-28 18:31:39 +00001634- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1635 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1636 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001643Mac
1644---
1645
1646- PythonLauncher now works correctly when the path to the script contains
1647 characters that are treated specially by the shell (such as quotes).
1648
1649- Bug #1527397: PythonLauncher now launches scripts with the working directory
1650 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001651 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001652 expect.

1662
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001663- Bug #1441486: The literal representation of -(sys.maxint - 1)
1664 again evaluates to a int object, not a long.
1665
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001666- Bug #1501934: The scope of global variables that are locally assigned
1667 using augmented assignment is now correctly determined.
1668
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001669- Bug #927248: Recursive method-wrapper objects can now safely
1670 be released.
1671
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001672- Bug #1417699: Reject locale-specific decimal point in float()
1673 and atof().
1674
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001675- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1676 omit a default "error" argument for NULL pointer. This allows
1677 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001678
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001679- Bug #1519018: 'as' is now validated properly in import statements.
1680
Neal Norwitz28746ab2006-07-09 22:14:42 +00001681- On 64 bit systems, int literals that use less than 64 bits are
1682 now ints rather than longs.
1683
Neal Norwitzed657552006-07-10 00:04:44 +00001684- Bug #1512814, Fix incorrect lineno's when code at module scope
1685 started after line 256.
1686
Tim Peters32a83612006-07-10 21:08:24 +00001687- New function ``sys._current_frames()`` returns a dict mapping thread
1688 id to topmost thread stack frame. This is for expert use, and is
1689 especially useful for debugging application deadlocks. The functionality
1690 was previously available in Fazal Majid's ``threadframe`` extension
1691 module, but it wasn't possible to do this in a wholly threadsafe way from
1692 an extension.

1698 VS 2003.
1699
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001700- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1701
Tim Peters32a83612006-07-10 21:08:24 +00001702- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001703 environment variable to be set in order to the SDK environment
1704 for finding the compiler, include files, etc.

1709
Thomas Woutersadd19112006-07-05 11:03:49 +00001710- string.Template() now correctly handles tuple-values. Previously,
1711 multi-value tuples would raise an exception and single-value tuples would
1712 be treated as the value they contain, instead.
1713
Martin v. Löwisede77f52006-07-03 13:01:35 +00001714- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1715 even if some data are received.
1716
Martin v. Löwis45482392006-07-03 12:28:58 +00001717- Bug #1267547: Put proper recursive setup.py call into the
1718 spec file generated by bdist_rpm.
1719
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001720- Bug #1514693: Update turtle's heading when switching between
1721 degrees and radians.
1722
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001723- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001724 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001725
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001726- Bug #1514703: Only setup canvas window in turtle when the canvas
1727 is created.
1728
Martin v. Löwis7596e832006-07-01 15:33:37 +00001729- Bug #1513223: .close() of a _socketobj now releases the underlying
1730 socket again, which then gets closed as it becomes unreferenced.

1733 attribute values.
1734
1735- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1736 sgmllib ('[' and ']' were not accepted).
1737
Georg Brandl1be63af2006-06-28 20:23:25 +00001738- Fix a bug in the turtle module's end_fill function.
1739
Brett Cannon53ab5b72006-06-22 16:49:14 +00001740- Bug #1510580: The 'warnings' module improperly required that a Warning
1741 category be either a types.ClassType and a subclass of Warning. The proper
1742 check is just that it is a subclass with Warning as the documentation states.
1743
Georg Brandlad29e632006-06-21 17:45:17 +00001744- The compiler module now correctly compiles the new try-except-finally
1745 statement (bug #1509132).
1746
Neal Norwitz60373cd2006-06-22 06:30:50 +00001747- The wsgiref package is now installed properly on Unix.
1748
Vinay Sajip28e57612006-07-01 10:45:20 +00001749- A bug was fixed in logging.config.fileConfig() which caused a crash on
1750 shutdown when fileConfig() was called multiple times.
1751
Gerhard Häring762fbd32006-07-02 17:48:30 +00001752- The sqlite3 module did cut off data from the SQLite database at the first
1753 null character before sending it to a custom converter. This has been fixed
1754 now.

1757-----------------
1758
Tim Peters112aad32006-07-19 00:03:19 +00001759- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1760 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1761 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001762
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001763- Assigning None to pointer type fields in ctypes structures possible
1764 overwrote the wrong fields, this is fixed now.
1765
1766- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1767 on non-Windows platforms.
1768
1769- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1770 integer or long, without range checking.
1771
1772- Patch #1517790: It is now possible to use custom objects in the ctypes
1773 foreign function argtypes sequence as long as they provide a from_param
1774 method, no longer is it required that the object is a ctypes type.
1775
1776- The '_ctypes' extension module now works when Python is configured
1777 with the --without-threads option.
1778
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001779- Bug #1513646: os.access on Windows now correctly determines write
1780 access, again.
1781
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001782- Bug #1512695: cPickle.loads could crash if it was interrupted with
1783 a KeyboardInterrupt.
1784
Neal Norwitza12aa882006-07-06 06:45:08 +00001785- Bug #1296433: parsing XML with a non-default encoding and
1786 a CharacterDataHandler could crash the interpreter in pyexpat.
1787

1794
Tim Peters32a83612006-07-10 21:08:24 +00001795- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001796 Previously, the slight difference could cause compilation errors of the
1797 'zlib' module on systems with more than one version of zlib.
1798
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001799- The MSI compileall step was fixed to also support a TARGETDIR

1830Core and builtins
1831-----------------
1832
Georg Brandla56b9152006-06-19 06:35:54 +00001833- Patch #1507676: Error messages returned by invalid abstract object operations
1834 (such as iterating over an integer) have been improved and now include the
1835 type of the offending object to help with debugging.
1836
Brett Cannonea3912b2006-06-13 21:46:41 +00001837- Bug #992017: A classic class that defined a __coerce__() method that returned
1838 its arguments swapped would infinitely recurse and segfault the interpreter.
1839
Neal Norwitz909eb122006-06-12 02:13:21 +00001840- Fix the socket tests so they can be run concurrently.
1841
Neal Norwitzb9845e72006-06-12 02:11:18 +00001842- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001843 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001844
Brett Cannon22565aa2006-06-09 22:31:23 +00001845- Bug #532646: object.__call__() will continue looking for the __call__
1846 attribute on objects until one without one is found. This leads to recursion
1847 when you take a class and set its __call__ attribute to an instance of the
1848 class. Originally fixed for classic classes, but this fix is for new-style.
1849 Removes the infinite_rec_3 crasher.
1850
Georg Brandl24250812006-06-09 18:45:48 +00001851- The string and unicode methods startswith() and endswith() now accept
1852 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1853
Brett Cannonde3b0522006-06-08 17:00:45 +00001854- Buffer objects, at the C level, never used the char buffer
1855 implementation even when the char buffer for the wrapped object was
1856 explicitly requested (originally returned the read or write buffer).
1857 Now a TypeError is raised if the char buffer is not present but is
1858 requested.
1859
Georg Brandlddbaa662006-06-04 21:56:52 +00001860- Patch #1346214: Statements like "if 0: suite" are now again optimized
1861 away like they were in Python 2.4.
1862
Georg Brandlb7c8f542006-05-27 12:30:25 +00001863- Builtin exceptions are now full-blown new-style classes instead of
1864 instances pretending to be classes, which speeds up exception handling
1865 by about 80% in comparison to 2.5a2.
1866
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001867- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1868 Unicode 4.1.
1869
Georg Brandlf4ef1162006-05-26 18:03:31 +00001870- Patch #921466: sys.path_importer_cache is now used to cache valid and
1871 invalid file paths for the built-in import machinery which leads to
1872 fewer open calls on startup.
1873
Tim Peters696cf432006-05-24 21:10:40 +00001874- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1875 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1876 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1877 the number of input digits (it was and remains linear-time for bases
1878 2, 4, 8, 16 and 32).
1879
Tim Petersb713ec22006-05-23 18:45:30 +00001880- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1881 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1882 an integer close to ``sys.maxint``. This was repaired by patch
1883 #1335972, which also gives a nice speedup.
1884
Richard Jonescebbefc2006-05-23 18:28:17 +00001885- Patch #1337051: reduced size of frame objects.
1886
1887- PyErr_NewException now accepts a tuple of base classes as its
1888 "base" parameter.
1889
Richard Jones7c88dcc2006-05-23 10:37:38 +00001890- Patch #876206: function call speedup by retaining allocated frame
1891 objects.
1892
Georg Brandl7b90e162006-05-18 07:01:27 +00001893- Bug #1462152: file() now checks more thoroughly for invalid mode
1894 strings and removes a possible "U" before passing the mode to the
1895 C library function.
1896
Neal Norwitz1004a532006-05-15 07:17:23 +00001897- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1898
Neal Norwitz373f0a72006-05-15 07:04:36 +00001899- Bug #1487966: Fix SystemError with conditional expression in assignment
1900
Martin v. Löwis879768d2006-05-11 13:28:43 +00001901- WindowsError now has two error code attributes: errno, which carries
1902 the error values from errno.h, and winerror, which carries the error
1903 values from winerror.h. Previous versions put the winerror.h values
1904 (from GetLastError()) into the errno attribute.
1905
Martin v. Löwis77736712006-05-04 05:51:03 +00001906- Patch #1475845: Raise IndentationError for unexpected indent.
1907
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001908- Patch #1479181: split open() and file() from being aliases for each other.
1909
Tim Peters44bd9862006-06-01 13:49:23 +00001910- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1911 methods were always silently ignored by dictionaries when comparing keys.
1912 They are now passed through (except when using the C API function
1913 ``PyDict_GetItem()``, whose semantics did not change).
1914
1915- Bug #1456209: In some obscure cases it was possible for a class with a
1916 custom ``__eq__()`` method to confuse dict internals when class instances
1917 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1918 No, you don't have any code that did this ;-)

1926
Brett Cannon6ee7d012006-06-08 16:23:04 +00001927- Change binascii.hexlify to accept a read-only buffer instead of only a char
1928 buffer and actually follow its documentation.
1929
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001930- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1931
Nick Coghlanc649ec52006-05-29 12:43:05 +00001932- Patch #1478788 (modified version): The functional extension module has
1933 been renamed to _functools and a functools Python wrapper module added.
1934 This provides a home for additional function related utilities that are
1935 not specifically about functional programming. See PEP 309.
1936
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001937- Patch #1493701: performance enhancements for struct module.

1942 copy() method.
1943
Andrew MacIntyre92913322006-06-13 15:04:24 +00001944- Patch #1454481: thread stack size is now tunable at runtime for thread
1945 enabled builds on Windows and systems with Posix threads support.
1946
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001947- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1948 (up to the system limit of 32K characters).
1949
1950- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1951 As a result, these functions now raise WindowsError instead of OSError.
1952
Tim Peters7a822da2006-05-25 21:50:17 +00001953- ``time.clock()`` on Win64 should use the high-performance Windows
1954 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1955 Windows platforms).
1956
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001957- Calling Tk_Init twice is refused if the first call failed as that
1958 may deadlock.
1959
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001960- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1961 accept it without potentially using an uninitialized pointer.
1962
1963- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1964 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
1965 patch numbers 1494885 and 1494902]

1971 parameter is supplied. [SF pybsddb bug #1477863]
1972
Gregory P. Smith3c228b12006-06-05 23:59:37 +00001973- bsddb: the __len__ method of a DB object has been fixed to return correct
1974 results. It could previously incorrectly return 0 in some cases.
1975 Fixes SF bug 1493322 (pybsddb bug 1184012).
1976
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001977- bsddb: the bsddb.dbtables Modify method now raises the proper error and
1978 aborts the db transaction safely when a modifier callback fails.
1979 Fixes SF python patch/bug #1408584.
1980
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001981- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001982 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001983 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1984 database calls that would previously deadlock. [SF python bug #775414]

2014 double-byte encodings.
2015
Tim Peters43898b42006-06-14 04:09:25 +00002016- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
2017 guarantee that adjacent triples in the return list always describe
2018 non-adjacent blocks. Previously, a pair of matching blocks could end
2019 up being described by multiple adjacent triples that formed a partition
2020 of the matching pair.
2021
Greg Ward0e0c9f42006-06-11 16:24:11 +00002022- Bug #1498146: fix optparse to handle Unicode strings in option help,

Greg Wardd1c797e2006-06-11 14:42:41 +00002025- Bug #1366250: minor optparse documentation error.
2026
Greg Ward7f547402006-06-11 00:40:49 +00002027- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
2028 clarify docs.
2029
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00002030- The wsgiref package has been added to the standard library.
2031
Nick Coghlan676725d2006-06-08 13:54:49 +00002032- The functions update_wrapper() and wraps() have been added to the functools
2033 module. These make it easier to copy relevant metadata from the original
2034 function when writing wrapper functions.
2035
Tim Petersd6a9eef2006-06-05 01:48:21 +00002036- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
2037 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00002038
Martin v. Löwis3f767792006-06-04 19:36:28 +00002039- Patch #1359618: Speed up charmap encoder by using a trie structure
2040 for lookup.
2041
Tim Petersd609b1a2006-06-02 23:22:51 +00002042- The functions in the ``pprint`` module now sort dictionaries by key
2043 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
2044 if and only if its display required more than one line, although that
2045 wasn't documented. The new behavior increases predictability; e.g.,
2046 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
2047
Georg Brandlfd9a4b12006-05-29 20:57:01 +00002048- Patch #1497027: try HTTP digest auth before basic auth in urllib2
2049 (thanks for J. J. Lee).
2050
Georg Brandl2b330372006-05-28 20:23:12 +00002051- Patch #1496206: improve urllib2 handling of passwords with respect to
2052 default HTTP and HTTPS ports.
2053
George Yoshidaf3c65de2006-05-28 16:39:09 +00002054- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
2055
Bob Ippolito7298f272006-05-23 18:43:47 +00002056- Patch #1281707: speed up gzip.readline.
2057
Georg Brandlb89316f2006-05-17 15:51:16 +00002058- Patch #1180296: Two new functions were added to the locale module:
2059 format_string() to get the effect of "format % items" but locale-aware,
2060 and currency() to format a monetary number with currency sign.
2061
Georg Brandle3a25832006-05-17 14:56:04 +00002062- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
2063 and several features added, such as speed and geometry control.
2064
Georg Brandl49c8f4c2006-05-15 19:30:35 +00002065- Patch #1488881: add support for external file objects in bz2 compressed
2066 tarfiles.
2067
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002068- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
2069 stdout arguments, making it possible to redirect input and output
2070 for remote debugging.
2071
2072- Patch #1484695: Update the tarfile module to version 0.8. This fixes
2073 a couple of issues, notably handling of long file names using the
2074 GNU LONGNAME extension.
2075
2076- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
2077 new flag when ``name`` is already the name of an option flag.
2078
2079- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
2080 package.
2081
2082- Patch #1472854: make the rlcompleter.Completer class usable on non-
2083 UNIX platforms.
2084
2085- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
2086
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00002087- Bug #1472827: correctly escape newlines and tabs in attribute values in
2088 the saxutils.XMLGenerator class.

2099
Neal Norwitz58e28882006-05-19 07:00:58 +00002100- Bug/Patch #1481770: Use .so extension for shared libraries on HP-UX for ia64.
2101
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002102- Patch #1471883: Add --enable-universalsdk.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00002118What's New in Python 2.5 alpha 2?
2119=================================
2120
2121*Release date: 27-APR-2006*
2122
2123Core and builtins
2124-----------------
2125
Thomas Heller1b046642006-04-18 18:51:06 +00002126- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2127 by converting these apis from macros into exported functions again:
2128
2129 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2130 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2131 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
2132 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
2133 PyRun_String Py_CompileString
2134
Martin v. Löwis45294a92006-04-18 06:24:08 +00002135- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2136
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002137- All uses of PyStructSequence_InitType have been changed to initialize
2138 the type objects only once, even if the interpreter is initialized
2139 multiple times.
2140
Neal Norwitz61546162006-04-14 05:20:28 +00002141- Bug #1454485, array.array('u') could crash the interpreter. This was
2142 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2143 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2144
2145- Py_UNICODE is unsigned. It was always documented as unsigned, but
2146 due to a bug had a signed value in previous versions.
2147
Tim Peters3a5e8b12006-04-11 01:44:07 +00002148- Patch #837242: ``id()`` of any Python object always gives a positive
2149 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2150 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002151 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002152 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002153
Tim Peters3a5e8b12006-04-11 01:44:07 +00002154 def __hash__(self):
2155 return id(self) # WRONG
2156
2157 because a hash result must be a (short) Python int but it was always
2158 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002159 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002160 was always usable as a hash value before this patch. That's no longer
2161 necessarily so.
2162
2163- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002164 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002165 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002166 #1454844)
2167
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002168- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2169 involving generators that have paused outside of any ``try`` or ``with``
2170 blocks. (In 2.5a1, a paused generator that was part of a reference
2171 cycle could not be garbage collected, regardless of whether it was
2172 paused in a ``try`` or ``with`` block.)
Anthony Baxter82201742006-04-09 15:07:40 +00002173
Anthony Baxter51bcb682006-04-05 14:51:42 +00002174Extension Modules

Martin v. Löwis7e75f1a2006-04-15 08:35:59 +00002177- Patch #1191065: Fix preprocessor problems on systems where recvfrom
2178 is a macro.
2179
Georg Brandlbbfe4fa2006-04-11 06:47:43 +00002180- Bug #1467952: os.listdir() now correctly raises an error if readdir()
2181 fails with an error condition.
2182
Gregory P. Smith3adc4aa2006-04-13 19:19:01 +00002183- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
2184
2185- Bug #1117761: bsddb.*open() no longer raises an exception when using
2186 the cachesize parameter.
2187
2188- Bug #1149413: bsddb.*open() no longer raises an exception when using
2189 a temporary db (file=None) with the 'n' flag to truncate on open.
2190
2191- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
2192 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00002193
Armin Rigoa9017c32006-04-19 11:50:27 +00002194- Patch #1062014: AF_UNIX sockets under Linux have a special
2195 abstract namespace that is now fully supported.

2199
Peter Astrand7d1d4362006-07-14 14:04:45 +00002200- Bug #1223937: subprocess.CalledProcessError reports the exit status
2201 of the process using the returncode attribute, instead of
2202 abusing errno.
2203
Tim Peters711bf302006-04-25 03:31:36 +00002204- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2205 a doctest to be skipped (the code is not run, and the expected output
2206 or exception is ignored).
2207
Nick Coghlanda2268f2006-04-24 04:37:15 +00002208- Fixed contextlib.nested to cope with exceptions being raised and
2209 caught inside exit handlers.
2210
Greg Wardab05edc2006-04-23 03:47:58 +00002211- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2212 hex, octal, or binary; add ``append_const`` action; keep going if
2213 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2214 added ``epilog`` for better help generation).
2215
Tim Peters21fbd572006-04-21 21:18:10 +00002216- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2217 called from a thread spawned as a side effect of importing a module.
2218
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002219- The pydoc module now supports documenting packages contained in
2220 .zip or .egg files.
2221
2222- The pkgutil module now has several new utility functions, such
2223 as ``walk_packages()`` to support working with packages that are either
2224 in the filesystem or zip files.
2225
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002226- The mailbox module can now modify and delete messages from
2227 mailboxes, in addition to simply reading them. Thanks to Gregory
2228 K. Johnson for writing the code, and to the 2005 Google Summer of
2229 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002230
Tim Petersc7605f22006-04-17 21:12:33 +00002231- The ``__del__`` method of class ``local`` in module ``_threading_local``
2232 returned before accomplishing any of its intended cleanup.
2233
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002234- Patch #790710: Add breakpoint command lists in pdb.
2235

2239
Anthony Baxtere29002c2006-04-12 12:07:31 +00002240- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
2241 Windows. Bug #1469163.
2242
Phillip J. Eby47032112006-04-11 01:07:43 +00002243- The warnings, linecache, inspect, traceback, site, and doctest modules
2244 were updated to work correctly with modules imported from zipfiles or
2245 via other PEP 302 __loader__ objects.
2246
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00002247- Patch #1467770: Reduce usage of subprocess._active to processes which
2248 the application hasn't waited on.

2259
Martin v. Löwis4be4e652006-04-17 19:25:49 +00002260- The Makefile now has a reindent target, which runs reindent.py on
2261 the library.
2262
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002263- Patch #1470875: Building Python with MS Free Compiler
2264

2268 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002269 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002270 CXX from --with-cxx-main, see description in README.
2271
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002272- Patch #1429775: Link extension modules with the shared libpython.

2275
Tim Peters8931ff12006-05-13 23:28:20 +00002276- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2277 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2278 and "%zu" for unsigned integers of type ``size_t``.
2279
Anthony Baxter51bcb682006-04-05 14:51:42 +00002280Tests
2281-----
2282
Nick Coghlanda2268f2006-04-24 04:37:15 +00002283- test_contextlib now checks contextlib.nested can cope with exceptions
2284 being raised and caught inside exit handlers.
2285
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002286- test_cmd_line now checks operation of the -m and -c command switches
2287
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002288- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2289 it separately and by hand. It also wasn't cleaning up its changes to
2290 the current Decimal context.
2291
Thomas Woutersabd08882006-04-26 15:53:30 +00002292- regrtest.py now has a -M option to run tests that test the new limits of
2293 containers, on 64-bit architectures. Running these tests is only sensible
2294 on 64-bit machines with more than two gigabytes of memory. The argument
2295 passed is the maximum amount of memory for the tests to use.

2307
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002308- PEP 343: Added Context Types section to the library reference
2309 and attempted to bring other PEP 343 related documentation into
2310 line with the implementation and/or python-dev discussions.
2311
Tim Peters8dc73d22006-04-24 02:03:16 +00002312- Bug #1337990: clarified that ``doctest`` does not support examples

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002316What's New in Python 2.5 alpha 1?
2317=================================
2318
Anthony Baxterebed3f62006-04-03 15:03:44 +00002319*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002320
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002321Core and builtins
2322-----------------
2323
Nick Coghlan43832302006-04-23 17:04:07 +00002324- PEP 338: -m command line switch now delegates to runpy.run_module
2325 allowing it to support modules in packages and zipfiles
2326
Martin v. Löwisc661b882006-04-20 04:54:23 +00002327- On Windows, .DLL is not an accepted file name extension for
2328 extension modules anymore; extensions are only found if they
2329 end in .PYD.
2330
Martin v. Löwisea62d252006-04-03 10:56:49 +00002331- Bug #1421664: sys.stderr.encoding is now set to the same value as
2332 sys.stdout.encoding.
2333
Neal Norwitz92e212f2006-04-03 04:48:37 +00002334- __import__ accepts keyword arguments.
2335
Georg Brandlccadf842006-03-31 18:54:53 +00002336- Patch #1460496: round() now accepts keyword arguments.
2337
Anthony Baxter262c00a2006-03-30 10:53:17 +00002338- Fixed bug #1459029 - unicode reprs were double-escaped.
2339
Hye-Shik Changd478f342006-03-23 12:32:36 +00002340- Patch #1396919: The system scope threads are reenabled on FreeBSD
2341 5.4 and later versions.
2342
Neal Norwitze98ccf62006-03-23 05:39:47 +00002343- Bug #1115379: Compiling a Unicode string with an encoding declaration
2344 now gives a SyntaxError.
2345
Georg Brandlabd1ff82006-03-18 07:59:59 +00002346- Previously, Python code had no easy way to access the contents of a
2347 cell object. Now, a ``cell_contents`` attribute has been added
2348 (closes patch #1170323).
2349
Tim Peterscf79aac2006-03-16 01:14:46 +00002350- Patch #1123430: Python's small-object allocator now returns an arena to
2351 the system ``free()`` when all memory within an arena becomes unused
2352 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2353 freed. Some applications will see a drop in virtual memory size now,
2354 especially long-running applications that, from time to time, temporarily
2355 use a large number of small objects. Note that when Python returns an
2356 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002357 platform C library will in turn return that memory to the operating system.
2358 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002359 appears to be effective at least on Microsoft C and gcc-based systems.
2360 Thanks to Evan Jones for hard work and patience.
2361
Georg Brandl533ff6f2006-03-08 18:09:27 +00002362- Patch #1434038: property() now uses the getter's docstring if there is
2363 no "doc" argument given. This makes it possible to legitimately use
2364 property() as a decorator to produce a read-only property.
2365
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002366- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2367 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2368 of requiring an int or long in slicing and a few other contexts, enabling
2369 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2370
Neal Norwitz995acdf2006-03-07 05:01:00 +00002371- Fixed various bugs reported by Coverity's Prevent tool.
2372
Brett Cannonbf364092006-03-01 04:25:17 +00002373- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2374 new exception base class, BaseException, which has a new message attribute.
2375 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2376 Raising a string exception now raises a DeprecationWarning.
2377
Thomas Woutersfb609f42006-02-28 16:37:25 +00002378- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2379 explicitly relative, using 'from .module import name' to mean 'from the same
2380 package as this module is in. Imports without dots still default to the
2381 old relative-then-absolute, unless 'from __future__ import
2382 absolute_import' is used.
2383
Brett Cannona7446e32006-02-27 23:39:10 +00002384- Properly check if 'warnings' raises an exception (usually when a filter set
2385 to "error" is triggered) when raising a warning for raising string
2386 exceptions.
2387
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002388- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002389 The name was removed from Include/code.h.
2390
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002391- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002392
Guido van Rossum1968ad32006-02-25 22:38:04 +00002393- Patch 1433928:
2394 - The copy module now "copies" function objects (as atomic objects).
2395 - dict.__getitem__ now looks for a __missing__ hook before raising
2396 KeyError.
2397
Tim Peters84ef21c2006-02-28 20:39:06 +00002398- PEP 343: with statement implemented. Needs ``from __future__ import
2399 with_statement``. Use of 'with' as a variable will generate a warning.
2400 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002401 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002402 The following objects have __context__ methods:
2403 - The built-in file type.
2404 - The thread.LockType type.
2405 - The following types defined by the threading module:
2406 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2407 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002408
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002409- Fix the encodings package codec search function to only search
2410 inside its own package. Fixes problem reported in patch #1433198.
2411
2412 Note: Codec packages should implement and register their own
2413 codec search function. PEP 100 has the details.
2414
Tim Peters9ea89d22006-06-04 03:26:02 +00002415- PEP 353: Using ``Py_ssize_t`` as the index type.
2416
2417- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2418 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2419 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2420 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2421 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002422
Neal Norwitzfc76d632006-01-10 06:03:13 +00002423- Patch #1400181, fix unicode string formatting to not use the locale.
2424 This is how string objects work. u'%f' could use , instead of .
2425 for the decimal point. Now both strings and unicode always use periods.
2426
Neal Norwitz671b9e32006-01-09 07:07:12 +00002427- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2428 configure would break checking curses.h.
2429
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002430- Bug #959576: The pwd module is now builtin. This allows Python to be
2431 built on UNIX platforms without $HOME set.
2432
Neal Norwitzc10978f2005-12-19 06:07:16 +00002433- Bug #1072182, fix some potential problems if characters are signed.
2434
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002435- Bug #889500, fix line number on SyntaxWarning for global declarations.
2436
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002437- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2438
Neal Norwitze7214a12005-12-18 05:03:17 +00002439- Support for converting hex strings to floats no longer works.
2440 This was not portable. float('0x3') now raises a ValueError.
2441
Barry Warsaw2a38a862005-12-18 01:27:35 +00002442- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002443 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002444 is now displayed in interactive prompt banner.
2445
Georg Brandlfa166682005-12-17 21:45:17 +00002446- Implementation of PEP 341 - Unification of try/except and try/finally.
2447 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002448 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002449
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002450- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2451 now encodes backslash correctly.
2452
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002453- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2454
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002455- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002456 and long longs.
2457
Neal Norwitz67715f02005-11-09 06:59:35 +00002458- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002459 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002460 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002461
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002462- Replaced most Unicode charmap codecs with new ones using the
2463 new Unicode translate string feature in the builtin charmap
2464 codec; the codecs were created from the mapping tables available
2465 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2466 encodings now include a mapping for the Apple logo)
2467
Tim Peterse3547fd2005-12-16 23:13:57 +00002468- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002469
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002470- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002471
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002472- A new AST parser implementation was completed. The abstract
2473 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002474 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002475
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002476- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002477 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2478
Neal Norwitz708e51a2005-10-03 04:48:15 +00002479- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2480
Neal Norwitz11bd1192005-10-03 00:54:56 +00002481- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2482 Provide a warning when a directory is passed on the command line.
2483
Neal Norwitz40d37812005-10-02 01:48:49 +00002484- Fix segfault with invalid coding.
2485
2486- SF bug #772896: unknown encoding results in MemoryError.
2487
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002488- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002489 supported a __len__() method which evaluated to False when the iterator
2490 was empty.
2491
Guido van Rossum630db602005-09-20 18:49:54 +00002492- On 64-bit platforms, when __len__() returns a value that cannot be
2493 represented as a C int, raise OverflowError.
2494
Skip Montanarof8948ca2005-09-19 03:54:46 +00002495- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002496 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002497
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002498- SF bug #893549: parsing keyword arguments was broken with a few format
2499 codes.
2500
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002501- Changes donated by Elemental Security to make it work on AIX 5.3
2502 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2503 bug #105470: test_pwd fails on 64bit system (Opteron).
2504
Guido van Rossum539c6622005-09-14 17:49:54 +00002505- Changes donated by Elemental Security to make it work on HP-UX 11 on
2506 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2507
Georg Brandl4550b8d2005-08-26 06:43:52 +00002508- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002509 (fixes bug #1119418).
2510
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002511- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2512
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002513- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2514 exceptions that cause a function to exit.
2515
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002516- The implementation of set() and frozenset() was revised to use its
2517 own internal data structure. Memory consumption is reduced by 1/3
2518 and there are modest speed-ups as well. The API is unchanged.
2519
Tim Petersde7990b2005-07-17 23:45:23 +00002520- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2521
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002522- SF bug #1229429: PyObject_CallMethod failed to decrement some
2523 reference counts in some error exit cases.
2524
Tim Petersecc6e6a2005-07-10 22:30:55 +00002525- SF bug #1185883: Python's small-object memory allocator took over
2526 a block managed by the platform C library whenever a realloc specified
2527 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002528 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002529 portable way to copy data from the C-managed block into Python's
2530 small-object space without risking a memory fault. Python's small-object
2531 realloc now leaves such blocks under the control of the platform C
2532 realloc.
2533
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002534- SF bug #1232517: An overflow error was not detected properly when
2535 attempting to convert a large float to an int in os.utime().
2536
Raymond Hettinger3296e692005-06-29 23:29:56 +00002537- SF bug #1224347: hex longs now print with lowercase letters just
2538 like their int counterparts.
2539
Michael W. Hudson188d4362005-06-20 16:52:57 +00002540- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2541 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2542 interpreter states; back out that fix and do a better job (see
2543 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2544 for a longer write-up of the problem).
2545
Michael W. Hudsondf888462005-06-03 14:41:55 +00002546- SF patch #1180995: marshal now uses a binary format by default when
2547 serializing floats.
2548
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002549- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2550 the routines that promise to produce IEEE 754 binary representations
2551 of floats now simply copy bytes around.
2552
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002553- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2554 278.
2555
Brett Cannonc3647ac2005-04-26 03:45:26 +00002556- patch #1109424: int, long, float, complex, and unicode now check for the
2557 proper magic slot for type conversions when subclassed. Previously the
2558 magic slot was ignored during conversion. Semantics now match the way
2559 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002560 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002561 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002562 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002563
Barry Warsawc8d907c2005-04-19 23:43:40 +00002564- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2565 NULL, now raise an AttributeError when attempting to set or delete the
2566 attribute. Previously a TypeError was raised, but this was inconsistent
2567 with the equivalent pure-Python implementation.
2568
Michael W. Hudson774479c2005-04-18 08:46:17 +00002569- It is now safe to call PyGILState_Release() before
2570 PyEval_InitThreads() (note that if there is reason to believe there
2571 are multiple threads around you still must call PyEval_InitThreads()
2572 before using the Python API; this fix is for extension modules that
2573 have no way of knowing if Python is multi-threaded yet).
2574
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002575- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2576 disabled caused a crash.
2577
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002578- Bug #1165306: instancemethod_new allowed the creation of a method
2579 with im_class == im_self == NULL, which caused a crash when called.
2580
Tim Petersecc6e6a2005-07-10 22:30:55 +00002581- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002582 fixes the crash seen in bug #1165761
2583
Raymond Hettinger96229b12005-03-11 06:49:40 +00002584- Added two new builtins, any() and all().
2585
Brett Cannon409d8f22005-03-05 06:47:57 +00002586- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002587 (e.g., ``class C(): pass`` is no longer a syntax error).
2588 Patch #1176012 added support to the 'parser' module and 'compiler' package
2589 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002590
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002591- Patch #1115086: Support PY_LONGLONG in structmember.
2592
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002593- Bug #1155938: new style classes did not check that __init__() was
2594 returning None.
2595
Tim Petersecc6e6a2005-07-10 22:30:55 +00002596- Patch #802188: Report characters after line continuation character

2624 calling __str__ on the argument returns a unicode instance.
2625
Tim Petersf4e69282006-02-27 17:15:31 +00002626- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2627 current thread state when the auto-GIL-state machinery knows about
2628 it (since the thread state is being deleted, continuing to remember it
2629 can't help, but can hurt if another thread happens to get created with
2630 the same thread id).

2838 in attribute values.
2839
Anthony Baxterc51ee692006-04-01 00:57:31 +00002840- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002841 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002842 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002843 module will not be built.

Tim Petersc17976e2006-04-01 00:26:53 +00002845- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2846 aren't officially supported here, and trying to use them will probably

2868
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002869- email 4.0 package now integrated. This is largely the same as the email 3.0
2870 package that was included in Python 2.3, except that PEP 8 module names are
2871 now used (e.g. mail.message instead of email.Message). The MIME classes
2872 have been moved to a subpackage (e.g. email.mime.text instead of
2873 email.MIMEText). The old names are still supported for now. Several
2874 deprecated Message methods have been removed and lots of bugs have been
2875 fixed. More details can be found in the email package documentation.

2878 (a subclass of tuple) that provides incremental decoders and encoders
2879 (a way to use stateful codecs without the stream API). Python functions
2880 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2881 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2882 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002883
Walter Dörwald067db482006-03-15 22:17:27 +00002884- Patch #1359365: Calling next() on a closed StringIO.String object raises
2885 a ValueError instead of a StopIteration now (like file and cString.String do).
2886 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2887 called before (like file and StringIO.StringIO do).

Tim Peterse3547fd2005-12-16 23:13:57 +00002961 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2962 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2963 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2964 Ronald L. Rivest offered this advice for Python:
2965
2966 "The consensus of researchers in this area (at least as
2967 expressed at the NIST Hash Function Workshop 10/31/05),
2968 is that SHA-256 is a good choice for the time being, but
2969 that research should continue, and other alternatives may
2970 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002971

Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00003127- Patch #1049151: xdrlib now unpacks booleans as True or False.
3128
Raymond Hettingerbab41432005-02-05 01:31:19 +00003129- Fixed bug in a NameError bug in cookielib. Patch #1116583.
3130
Guido van Rossumd0641422005-02-03 15:01:24 +00003131- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
3132 disables recursive traversal through instance attributes, which can
3133 be exploited in various ways.
3134
Tim Peterse3547fd2005-12-16 23:13:57 +00003135- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00003136 flags on the HTTP listening socket.
3137
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00003138- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
3139 Fixed by reading the HTTP body in chunks instead of one big socket.read().
3140
Fred Drakefbdeaad2006-07-29 16:56:15 +00003141- Patches #893642, #1039083: add allow_none, encoding arguments to
3142 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.

3147
Martin v. Löwis22b457e2005-01-16 08:40:58 +00003148- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
3149
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003150- Enhancements to the csv module:
3151
3152 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003153 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003154 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003155 + Dialect parameter parsing has been re-implemented to improve error
3156 reporting.
3157 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3158 dictates.
3159 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003160 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003161 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003162 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3163 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003164 + reader now allows \r characters to be quoted (previously it only allowed
3165 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003166 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003167 + Dialect classes passed to the module are no longer instantiated by
3168 the module before being parsed (the former validation scheme required
3169 this, but the mechanism was unreliable).
3170 + The dialect registry now contains instances of the internal
3171 C-coded dialect type, rather than references to python objects.
3172 + the internal c-coded dialect type is now immutable.
3173 + register_dialect now accepts the same keyword dialect specifications
3174 as the reader and writer, allowing the user to register dialects
3175 without first creating a dialect class.
3176 + a configurable limit to the size of parsed fields has been added -
3177 previously, an unmatched quote character could result in the entire
3178 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003179 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003180 the parser field size limit (returning the former limit). The initial
3181 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003182 + A line_num attribute has been added to the reader object, which tracks
3183 the number of lines read from the source iterator. This is not
3184 the same as the number of records returned, as records can span
3185 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003186 + reader and writer objects were not being registered with the cyclic-GC.
3187 This has been fixed.
3188
Brett Cannone6539c42005-01-08 02:43:53 +00003189- _DummyThread objects in the threading module now delete self.__block that is
3190 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3191 lock primitives tend to be limited in number and thus should not be wasted on
3192 a _DummyThread object. Fixes bug #1089632.
3193
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003194- The imghdr module now detects Exif files.
3195
Raymond Hettinger6065d322004-12-20 23:51:53 +00003196- StringIO.truncate() now correctly adjusts the size attribute.
3197 (Bug #951915).
3198
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003199- locale.py now uses an updated locale alias table (built using
3200 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3201 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003202 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003203
Raymond Hettinger3557f422004-12-07 12:02:02 +00003204- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3205
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003206- the pickle module no longer accepts the deprecated None option in the
3207 args tuple returned by __reduce__().
3208
Brett Cannon84667c02004-12-07 03:25:18 +00003209- optparse now optionally imports gettext. This allows its use in setup.py.
3210
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003211- the pickle module no longer uses the deprecated bin parameter.
3212
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003213- the shelve module no longer uses the deprecated binary parameter.
3214
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003215- the pstats module no longer uses the deprecated ignore() method.
3216
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003217- the filecmp module no longer uses the deprecated use_statcache argument.
3218
Raymond Hettinger664347b2004-12-04 21:21:53 +00003219- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3220 extended or overridden by subclasses. Formerly, the subclassed method would
3221 be ignored by the rest of the module. (Bug #1078905).
3222
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003223- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003224 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003225
Walter Dörwald36733692004-12-22 12:50:50 +00003226- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3227 once when a size argument is given. This prevents a buffer overflow in the
3228 tokenizer with very long source lines.
3229
Barry Warsaw538561e2006-01-01 21:48:54 +00003230- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3231 immediately after creating the object, without any intervening
3232 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003233
Skip Montanaro05885812005-01-16 20:48:27 +00003234- The reconvert.quote function can now emit triple-quoted strings. The
3235 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003236
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003237- ``UserString.MutableString`` now supports negative indices in
3238 ``__setitem__`` and ``__delitem__``
3239
Greg Ward40407942005-03-05 02:53:17 +00003240- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3241 correctly.
3242
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003243- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3244 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3245 character even if the user has passed a size parameter to get a proper
3246 line ending. Remove the special handling of a "\r\n" that has been split
3247 between two lines.
3248
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003249- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3250 about illegal code points. The codec now supports PEP 293 style error
3251 handlers.
3252
Walter Dörwald78a78b02005-09-01 12:04:29 +00003253- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003254 from the input stream, so that the output is a byte string in the correct
3255 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003256
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003257- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3258 considering it exactly like a '*'.
3259
Walter Dörwald007f8df2005-10-09 19:42:27 +00003260- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3261 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003262
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003263- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3264
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003265- Patch #1413711: Certain patterns of differences were making difflib
3266 touch the recursion limit.
3267
Walter Dörwald58917a62006-03-31 15:26:22 +00003268- Bug #947906: An object oriented interface has been added to the calendar
3269 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003270 called as a script (e.g. via ``python -mcalendar``). Localized month and
3271 weekday names can be ouput (even if an exotic encoding is used) using
3272 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003273
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003274Build
3275-----
3276
Neal Norwitz602d3392006-03-31 08:21:40 +00003277- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3278 by using -mieee gcc option.
3279
Martin v. Löwis86d66262006-02-17 08:40:11 +00003280- Patch #1432345: Make python compile on DragonFly.
3281
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003282- Build support for Win64-AMD64 was added.
3283
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003284- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3285
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003286- Patch #881820: look for openpty and forkpty also in libbsd.
3287
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003288- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3289 The zlib module is now builtin on Windows.
3290
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003291- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3292
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003293- Bug #1189330: configure did not correctly determine the necessary
3294 value of LINKCC if python was built with GCC 4.0.
3295
Trent Mick8321b422005-07-26 02:29:21 +00003296- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3297 vulnerability in zlib 1.2.1 and 1.2.2.
3298
Brett Cannon08cd5982005-04-24 22:26:38 +00003299- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3300 flags that change binary compatibility. Changes were also made to
3301 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003302 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003303
Bob Ippolitoed233462005-03-29 13:47:59 +00003304- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3305 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3306 no longer exists). This configure patch makes things right.
3307
Martin v. Löwise2713be2005-03-08 15:03:08 +00003308- Bug #1158607: Build with --disable-unicode again.
3309
Brett Cannon46d96232005-02-16 00:07:19 +00003310- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3311 defined. Discovered as a result of not being able to build on OS X.
3312
Brett Cannon516592f2004-12-07 00:42:59 +00003313- setup.py now uses the directories specified in LDFLAGS using the -L option
3314 and in CPPFLAGS using the -I option for adding library and include
3315 directories, respectively, for compiling extension modules against. This has
3316 led to the core being compiled using the values in CPPFLAGS. It also removes
3317 the need for the special-casing of both DarwinPorts and Fink for darwin since
3318 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3319 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3320 Fink, ``-I/opt/local/include`` for DarwinPorts).
3321
Brett Cannon43802422005-02-10 20:48:03 +00003322- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3323 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3324 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3325 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003327C API
3328-----
3329
Tim Petersc9d78aa2006-03-26 23:27:58 +00003330- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3331 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3332 is obtained via the ``PyObject_`` family, it must be released via the
3333 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3334 always been officially true, but when Python's small-object allocator was
3335 introduced, an attempt was made to cater to a few extension modules
3336 discovered at the time that obtained memory via ``PyObject_New`` but
3337 released it via ``PyMem_DEL``. It's years later, and if such code still
3338 exists it will fail now (probably with segfaults, but calling wrong
3339 low-level memory management functions can yield many symptoms).
3340
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003341- Added a C API for set and frozenset objects.
3342
Raymond Hettinger66517482004-12-03 11:45:13 +00003343- Removed PyRange_New().
3344
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003345- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3346 mapping argument now. This string is used as a mapping table. Byte values
3347 greater than the length of the string and 0xFFFE are treated as undefined
3348 mappings.
