Amaury Forgeot d'Arcb50f9922008-09-26 22:46:01 +000061- Issue #3967: Fixed a crash in the count() and find() methods of string-like
62 objects, when the "start" parameter is a huge value.

74
Neal Norwitz83ac0142008-07-28 05:06:20 +000075- Issue #2620: Overflow checking when allocating or reallocating memory
76 was not always being done properly in some python types and extension
77 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have

91
Amaury Forgeot d'Arcb15bdf72008-07-01 20:59:49 +000092- Issue #3088: Corrected a race condition in classes derived from

98
Guido van Rossumaa975432008-04-10 22:43:58 +000099- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
100 having a self-referential tuple, which is possible from C code. Nor did
101 object's tp_str consider that a type's tp_str could do something that could
102 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
103 respectively, fixed the issues. (Backport of r58288 from trunk.)

112 \Uxxxxxxxx did not accept values outside the Basic Multilingual Plane. This
113 affected raw unicode literals and the 'raw-unicode-escape' codec. Now
114 UTF-16 surrogates are generated in this case, like normal unicode literals
115 and the 'unicode-escape' codec.
116
Neal Norwitzb3635f92008-03-18 04:17:36 +0000117- Issue #2321: use pymalloc for unicode object string data to reduce
118 memory usage in some circumstances.
Andrew M. Kuchlingbe0adfc2008-02-23 17:18:19 +0000119
Sean Reifscheider4af861c2008-03-20 17:39:31 +0000120- Issue #2238: Some syntax errors in *args and **kwargs expressions could give
121 bogus error messages.
122

124 parameter but was not verifying that it was greater than zero. Values
125 less than zero will now raise a SystemError and return NULL to indicate a
126 bug in the calling C code.
127
Gregory P. Smith9aa040d2008-06-02 00:07:25 +0000128- Issue #2588, #2589: Fix potential integer underflow and overflow
129 conditions in the PyOS_vsnprintf C API function.
130
Gregory P. Smithcae7f882008-09-07 06:44:12 +0000131- Issue #1204: The configure script now tests for additional libraries
132 that may be required when linking against readline. This fixes issues
133 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
Georg Brandld9f1da02008-03-29 01:50:46 +0000134
Gregory P. Smitha7a94a02008-09-22 00:22:44 +0000135- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
136 library targets in the Makefile.

Amaury Forgeot d'Arc22679b82008-08-18 19:33:42 +0000174- Issue #2234: distutils failed for some versions of the cygwin compiler. The
175 version reported by these tools does not necessarily follow the python
176 version numbering scheme, so the module is less strict when parsing it.
177
Hirokazu Yamamoto1d63a452008-08-17 09:49:10 +0000178- Issue #2222: Fixed reference leak when occured os.rename()

1162-----------------
1163
Neal Norwitz0bcafac2006-09-11 08:51:17 +00001164- Make _PyGILState_NoteThreadState() static, it was not used anywhere
1165 outside of pystate.c and should not be necessary.
1166
Brett Cannon19d76c52006-09-09 07:18:44 +00001167- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
1168 allows calling unicode() on exceptions classes directly to succeed.
1169
Georg Brandlecab6232006-09-06 06:47:02 +00001170- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
1171 Also make sure that every exception class has __module__ set to
1172 'exceptions'.
1173
Georg Brandl37a9e572006-09-06 06:09:34 +00001174- Bug #1550983: emit better error messages for erroneous relative
1175 imports (if not in package and if beyond toplevel package).
1176
Tim Peterscbdd3502006-09-05 01:47:53 +00001177- Overflow checking code in integer division ran afoul of new gcc
1178 optimizations. Changed to be more standard-conforming.

1184
Neal Norwitz29a5fdb2006-09-05 02:21:38 +00001185- The return tuple from str.rpartition(sep) is (tail, sep, head) where
1186 head is the original string if sep was not found.
1187
Neal Norwitz3b3aae02006-09-05 03:56:01 +00001188- Bug #1520864: unpacking singleton tuples in list comprehensions and
1189 generator expressions (x for x, in ... ) works again. Fixing this problem
1190 required changing the .pyc magic number. This means that .pyc files
1191 generated before 2.5c2 will be regenerated.
1192
Neal Norwitz19c35bb2006-08-21 22:13:11 +00001193

Guido van Rossumc69ac252006-08-10 18:09:25 +00001298What's New in Python 2.5 release candidate 1?
1299=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001300
Anthony Baxterb4096662006-08-16 03:42:26 +00001301*Release date: 17-AUG-2006*
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001302
1303Core and builtins
1304-----------------
1305
Neal Norwitz24b6f202006-09-05 04:43:56 +00001306- Fix infinite recursion when subclassing long and overriding __hash__.
1307
1308- Fix concatenation (+=) of long strings.
1309
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001310- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001311 compared equal or unequal to a string and a UnicodeDecodeError
1312 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001313
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001314 Instead, the equal (==) and unequal (!=) comparison operators will
1315 now issue a UnicodeWarning and interpret the two objects as
1316 unequal. The UnicodeWarning can be filtered as desired using
1317 the warning framework, e.g. silenced completely, turned into an
1318 exception, logged, etc.
1319
1320 Note that compare operators other than equal and unequal will still
1321 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001322
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001323- Fix segfault when doing string formatting on subclasses of long.
1324
1325- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1326 with new-style classes.
1327
1328- Fix bug related to __len__ functions returning negative values with
1329 classic classes.
1330
1331- Patch #1538606, Fix __index__() clipping. There were some problems
1332 discovered with the API and how integers that didn't fit into Py_ssize_t
1333 were handled. This patch attempts to provide enough alternatives
1334 to effectively use __index__.
1335
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001336- Bug #1536021: __hash__ may now return long int; the final hash
1337 value is obtained by invoking hash on the long int.
1338
Thomas Hellerab1049c2006-08-08 17:37:00 +00001339- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1340
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001341- Bug #1535165: fixed a segfault in input() and raw_input() when
1342 sys.stdin is closed.
1343
Thomas Heller74d36f02006-08-04 18:17:40 +00001344- On Windows, the PyErr_Warn function is now exported from
1345 the Python dll again.
1346
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001347- Bug #1191458: tracing over for loops now produces a line event
1348 on each iteration. Fixing this problem required changing the .pyc
1349 magic number. This means that .pyc files generated before 2.5c1
1350 will be regenerated.
1351
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001352- Bug #1333982: string/number constants were inappropriately stored
1353 in the byte code and co_consts even if they were not used, ie
1354 immediately popped off the stack.
1355
Georg Brandle9462c72006-08-04 18:03:37 +00001356- Fixed a reference-counting problem in property().
1357
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001358
1359Library
1360-------
1361
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001362- Fix a bug in the ``compiler`` package that caused invalid code to be
1363 generated for generator expressions.
1364
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001365- The distutils version has been changed to 2.5.0. The change to
1366 keep it programmatically in sync with the Python version running
1367 the code (introduced in 2.5b3) has been reverted. It will continue
1368 to be maintained manually as static string literal.
1369
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001370- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001371 and this cannot be converted to the required C type, an exception is
1372 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001373 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001374
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001375- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001376 an exception.
1377
Tim Peterscbdd3502006-09-05 01:47:53 +00001378- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001379 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001380 workarounds for clocks with low resolution, to stop the code yielding
1381 duplicate UUIDs.
1382
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001383- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1384 before raising SystemExit, allowing IDLE to honor quit() and exit().
1385
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001386- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1387
Georg Brandl7a1af772006-08-14 21:55:28 +00001388- Patch #1536071: trace.py should now find the full module name of a
1389 file correctly even on Windows.
1390
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001391- logging's atexit hook now runs even if the rest of the module has
1392 already been cleaned up.
1393
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001394- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001395
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001396- Bug #1531405, format_exception no longer raises an exception if
1397 str(exception) raised an exception.
1398
Neil Schemenauer06ded092006-08-04 16:20:30 +00001399- Fix a bug in the ``compiler`` package that caused invalid code to be
1400 generated for nested functions.

1411 raises the correct exceptions.
1412
Thomas Heller1ce433e2006-08-14 16:20:04 +00001413- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The

1415
Thomas Heller86720042006-08-14 11:17:48 +00001416- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1417 uses the _as_parameter_ attribute when objects are passed to foreign
1418 function calls. The ctypes version number was changed to 1.0.1.
1419
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001420- Bug #1530559, struct.pack raises TypeError where it used to convert.
1421 Passing float arguments to struct.pack when integers are expected
1422 now triggers a DeprecationWarning.

Thomas Hellerdb7b4432006-08-04 19:49:31 +00001451- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.
1452
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001453- Bug #1530448, ctypes build failure on Solaris 10 was fixed.

Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001459- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1460
Tim Peters4643c2f2006-08-10 22:45:34 +00001461- Bug #1069160. Internal correctness changes were made to
1462 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1463 the documentation was changed to state that the return value
1464 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001467What's New in Python 2.5 beta 3?
1468================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001469
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001470*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001471
1472Core and builtins
1473-----------------
1474
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001475- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001476 returned a long (see PEP 353).
1477
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001478- Bug #1515471: string.replace() accepts character buffers again.
1479
Neal Norwitz07aadb12006-07-30 06:55:48 +00001480- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1481 This provides the proper warning for struct.pack().
1482 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1483
Neal Norwitz0d62a062006-07-30 06:53:31 +00001484- Patch #1531113: Fix augmented assignment with yield expressions.
1485 Also fix a SystemError when trying to assign to yield expressions.
1486
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001487- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1488 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1489 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1490 excessive filesystem operations during imports.
1491
Tim Petersbc24eee2006-07-27 01:14:53 +00001492- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1493 operations on signed longs that are formally undefined by C.
1494 Unfortunately, at least one compiler now cares about that, so complicated
1495 the code to make that compiler happy again.
1496
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001497- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1498
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001499- Patch #1232023: Stop including current directory in search
1500 path on Windows.
1501
Neal Norwitze1fdb322006-07-21 05:32:28 +00001502- Fix some potential crashes found with failmalloc.
1503
Neal Norwitze7563102006-07-17 01:00:16 +00001504- Fix warnings reported by Klocwork's static analysis tool.
1505
Neal Norwitz84be93b2006-07-16 01:50:38 +00001506- Bug #1512814, Fix incorrect lineno's when code within a function
1507 had more than 255 blank lines.
1508
Georg Brandl9dceedb2006-07-12 15:31:17 +00001509- Patch #1521179: Python now accepts the standard options ``--help`` and
1510 ``--version`` as well as ``/?`` on Windows.
1511
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001512- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001513 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001514 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001515
Tim Peters112aad32006-07-19 00:03:19 +00001516- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001517 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001518 new ``sys._current_frames()`` returns a dictionary with one entry,
1519 mapping the faux "thread id" 0 to the current frame.
1520
Ronald Oussoren3075e162006-07-25 20:28:55 +00001521- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001522

Neal Norwitza1f10902006-07-12 07:28:29 +00001524Library
1525-------
1526
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001527- Correction of patch #1455898: In the mbcs decoder, set final=False
1528 for stream decoder, but final=True for the decode function.
1529
Georg Brandl07fec3a2006-08-01 18:49:24 +00001530- os.urandom no longer masks unrelated exceptions like SystemExit or
1531 KeyboardInterrupt.
1532
Tim Peters4643c2f2006-08-10 22:45:34 +00001533- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001534 shutil.copytree on Windows
1535
Georg Brandle34ac7c2006-07-30 11:07:23 +00001536- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1537 refers to file descriptors, not file objects.
1538
Tim Peterscbdd3502006-09-05 01:47:53 +00001539- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001540 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001541 #1513611, and probably others.
1542
Georg Brandledd9b0d2006-07-29 09:33:26 +00001543- Bug #1441397: The compiler module now recognizes module and function
1544 docstrings correctly as it did in Python 2.4.
1545
Tim Peters6f681472006-07-27 23:44:37 +00001546- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1547 lost that tests are sorted by name before being run. This rarely
1548 matters for well-written tests, but can create baffling symptoms if
1549 side effects from one test to the next affect outcomes. ``DocTestFinder``
1550 has been changed to sort the list of tests it returns.
1551
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001552- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001553 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001554
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001555- Bug #978833: Really close underlying socket in _socketobject.close.
1556
Georg Brandldb232dc2006-08-20 13:15:43 +00001557- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1558 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001559
Georg Brandlcf0c1722006-07-26 07:23:32 +00001560- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1561 to recursive calls and call it with the failing package name.
1562
Martin v. Löwis0b483032006-07-25 09:53:12 +00001563- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1564
Georg Brandlc13c34c2006-07-24 14:09:56 +00001565- Patch #1515343: Fix printing of deprecated string exceptions with a
1566 value in the traceback module.
1567
Greg Ward48fae7a2006-07-23 16:05:51 +00001568- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1569
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001570- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1571
Brett Cannoncaebe222006-07-18 04:41:36 +00001572- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1573 argument tuple. For arguments where zero is illegal, the value is forced to
1574 the minimum value that is correct. This is to support an undocumented but
1575 common way people used to fill in inconsequential information in the time
1576 tuple pre-2.4.
1577
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001578- Patch #1220874: Update the binhex module for Mach-O.
1579
Barry Warsawb110bad2006-07-21 14:51:07 +00001580- The email package has improved RFC 2231 support, specifically for
1581 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1582 (name*0=<blah>) parameter continuations. This may change the types of
1583 values returned from email.message.Message.get_param() and friends.
1584 Specifically in some cases where non-encoded continuations were used,
1585 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1586 will just return the string (since non-encoded continuations don't have
1587 charset and language parts).
1588
1589 Also, whereas % values were decoded in all parameter continuations, they are
1590 now only decoded in encoded parameter parts.
1591
Ronald Oussoren3075e162006-07-25 20:28:55 +00001592- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1593
1594- Bug #1517996: IDLE now longer shows the default Tk menu when a
1595 path browser, class browser or debugger is the frontmost window on MacOS X
1596
Barry Warsaw00decd72006-07-27 23:43:15 +00001597- Patch #1520294: Support for getset and member descriptors in types.py,
1598 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1599 of an object against these built-in types and more importantly, for getting
1600 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001603Extension Modules
1604-----------------
1605
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001606- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1607 a socket operation on a socket with a timeout, the exception will be
1608 caught correctly. Previously, the exception was not caught.
1609
Thomas Heller1393d6a2006-07-28 21:43:20 +00001610- Patch #1529514: The _ctypes extension is now compiled on more
1611 openbsd target platforms.
1612
Tim Peters9cab5932006-07-28 00:30:00 +00001613- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1614 a memory leak, affecting pickles and deep copies.
1615
Tim Petersbc24eee2006-07-27 01:14:53 +00001616- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001617 Paul Eggert.
1618
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001619- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1620
Thomas Hellerce049a02006-07-14 17:51:14 +00001621- Patch #1521817: Index range checking on ctypes arrays containing
1622 exactly one element enabled again. This allows iterating over these
1623 arrays, without the need to check the array size before.
1624
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001625- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001626 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001627 /dev/null in certain cases; this is now fixed.
1628
Thomas Heller47d7a062006-07-12 08:43:47 +00001629- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1630 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001631
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001632- Because of a misspelled preprocessor symbol, ctypes was always
1633 compiled without thread support; this is now fixed.
1634
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001635- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1636 methods now allow their database parameter to be None as the
1637 sleepycat API allows.
1638
Matt Flemingec926502006-07-28 11:27:27 +00001639- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1640 bluetooth API compared with Linux and FreeBSD.
1641
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001642Tests
1643-----
1644
1645- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1646 how long the test file should take to play. Now accepts taking 2.93 secs
1647 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1648
Georg Brandl4793aa32006-07-28 18:31:39 +00001649- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1650 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1651 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001658Mac
1659---
1660
1661- PythonLauncher now works correctly when the path to the script contains
1662 characters that are treated specially by the shell (such as quotes).
1663
1664- Bug #1527397: PythonLauncher now launches scripts with the working directory
1665 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001666 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001667 expect.

1676-----------------
1677
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001678- Bug #1441486: The literal representation of -(sys.maxint - 1)
1679 again evaluates to a int object, not a long.
1680
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001681- Bug #1501934: The scope of global variables that are locally assigned
1682 using augmented assignment is now correctly determined.
1683
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001684- Bug #927248: Recursive method-wrapper objects can now safely
1685 be released.
1686
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001687- Bug #1417699: Reject locale-specific decimal point in float()
1688 and atof().
1689
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001690- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1691 omit a default "error" argument for NULL pointer. This allows
1692 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001693
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001694- Bug #1519018: 'as' is now validated properly in import statements.
1695
Neal Norwitz28746ab2006-07-09 22:14:42 +00001696- On 64 bit systems, int literals that use less than 64 bits are
1697 now ints rather than longs.
1698
Neal Norwitzed657552006-07-10 00:04:44 +00001699- Bug #1512814, Fix incorrect lineno's when code at module scope
1700 started after line 256.
1701
Tim Peters32a83612006-07-10 21:08:24 +00001702- New function ``sys._current_frames()`` returns a dict mapping thread
1703 id to topmost thread stack frame. This is for expert use, and is
1704 especially useful for debugging application deadlocks. The functionality
1705 was previously available in Fazal Majid's ``threadframe`` extension
1706 module, but it wasn't possible to do this in a wholly threadsafe way from
1707 an extension.

Martin v. Löwis77621582006-07-30 13:27:31 +00001712- Bug #1257728: Mention Cygwin in distutils error message about a missing
1713 VS 2003.
1714
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001715- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1716
Tim Peters32a83612006-07-10 21:08:24 +00001717- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001718 environment variable to be set in order to the SDK environment
1719 for finding the compiler, include files, etc.

1724
Thomas Woutersadd19112006-07-05 11:03:49 +00001725- string.Template() now correctly handles tuple-values. Previously,
1726 multi-value tuples would raise an exception and single-value tuples would
1727 be treated as the value they contain, instead.
1728

Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001740
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001741- Bug #1514703: Only setup canvas window in turtle when the canvas
1742 is created.
1743
Martin v. Löwis7596e832006-07-01 15:33:37 +00001744- Bug #1513223: .close() of a _socketobj now releases the underlying
1745 socket again, which then gets closed as it becomes unreferenced.
1746
Fred Drake10497c82006-06-29 02:57:48 +00001747- Bug #1504333: Make sgmllib support angle brackets in quoted
1748 attribute values.
1749
1750- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1751 sgmllib ('[' and ']' were not accepted).
1752

1754
Brett Cannon53ab5b72006-06-22 16:49:14 +00001755- Bug #1510580: The 'warnings' module improperly required that a Warning
1756 category be either a types.ClassType and a subclass of Warning. The proper
1757 check is just that it is a subclass with Warning as the documentation states.
1758
Georg Brandlad29e632006-06-21 17:45:17 +00001759- The compiler module now correctly compiles the new try-except-finally
1760 statement (bug #1509132).
1761
Neal Norwitz60373cd2006-06-22 06:30:50 +00001762- The wsgiref package is now installed properly on Unix.
1763

1765 shutdown when fileConfig() was called multiple times.
1766
Gerhard Häring762fbd32006-07-02 17:48:30 +00001767- The sqlite3 module did cut off data from the SQLite database at the first
1768 null character before sending it to a custom converter. This has been fixed
1769 now.
1770
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001771Extension Modules
1772-----------------
1773
Tim Peters112aad32006-07-19 00:03:19 +00001774- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1775 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1776 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001777
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001778- Assigning None to pointer type fields in ctypes structures possible
1779 overwrote the wrong fields, this is fixed now.
1780
1781- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1782 on non-Windows platforms.
1783
1784- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1785 integer or long, without range checking.
1786
1787- Patch #1517790: It is now possible to use custom objects in the ctypes
1788 foreign function argtypes sequence as long as they provide a from_param
1789 method, no longer is it required that the object is a ctypes type.
1790
1791- The '_ctypes' extension module now works when Python is configured
1792 with the --without-threads option.
1793
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001794- Bug #1513646: os.access on Windows now correctly determines write
1795 access, again.
1796
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001797- Bug #1512695: cPickle.loads could crash if it was interrupted with

1809
Tim Peters32a83612006-07-10 21:08:24 +00001810- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001811 Previously, the slight difference could cause compilation errors of the
1812 'zlib' module on systems with more than one version of zlib.
1813
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001814- The MSI compileall step was fixed to also support a TARGETDIR

Anthony Baxter51bcb682006-04-05 14:51:42 +00001844
1845Core and builtins
1846-----------------
1847
Georg Brandla56b9152006-06-19 06:35:54 +00001848- Patch #1507676: Error messages returned by invalid abstract object operations
1849 (such as iterating over an integer) have been improved and now include the
1850 type of the offending object to help with debugging.
1851
Brett Cannonea3912b2006-06-13 21:46:41 +00001852- Bug #992017: A classic class that defined a __coerce__() method that returned
1853 its arguments swapped would infinitely recurse and segfault the interpreter.
1854
Neal Norwitz909eb122006-06-12 02:13:21 +00001855- Fix the socket tests so they can be run concurrently.
1856
Neal Norwitzb9845e72006-06-12 02:11:18 +00001857- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001858 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001859
Brett Cannon22565aa2006-06-09 22:31:23 +00001860- Bug #532646: object.__call__() will continue looking for the __call__
1861 attribute on objects until one without one is found. This leads to recursion
1862 when you take a class and set its __call__ attribute to an instance of the
1863 class. Originally fixed for classic classes, but this fix is for new-style.
1864 Removes the infinite_rec_3 crasher.
1865
Georg Brandl24250812006-06-09 18:45:48 +00001866- The string and unicode methods startswith() and endswith() now accept
1867 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1868
Brett Cannonde3b0522006-06-08 17:00:45 +00001869- Buffer objects, at the C level, never used the char buffer
1870 implementation even when the char buffer for the wrapped object was
1871 explicitly requested (originally returned the read or write buffer).
1872 Now a TypeError is raised if the char buffer is not present but is
1873 requested.
1874
Georg Brandlddbaa662006-06-04 21:56:52 +00001875- Patch #1346214: Statements like "if 0: suite" are now again optimized
1876 away like they were in Python 2.4.
1877
Georg Brandlb7c8f542006-05-27 12:30:25 +00001878- Builtin exceptions are now full-blown new-style classes instead of
1879 instances pretending to be classes, which speeds up exception handling
1880 by about 80% in comparison to 2.5a2.
1881
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001882- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1883 Unicode 4.1.
1884
Georg Brandlf4ef1162006-05-26 18:03:31 +00001885- Patch #921466: sys.path_importer_cache is now used to cache valid and
1886 invalid file paths for the built-in import machinery which leads to
1887 fewer open calls on startup.
1888
Tim Peters696cf432006-05-24 21:10:40 +00001889- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1890 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1891 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1892 the number of input digits (it was and remains linear-time for bases
1893 2, 4, 8, 16 and 32).
1894
Tim Petersb713ec22006-05-23 18:45:30 +00001895- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1896 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1897 an integer close to ``sys.maxint``. This was repaired by patch
1898 #1335972, which also gives a nice speedup.
1899
Richard Jonescebbefc2006-05-23 18:28:17 +00001900- Patch #1337051: reduced size of frame objects.
1901
1902- PyErr_NewException now accepts a tuple of base classes as its
1903 "base" parameter.
1904
Richard Jones7c88dcc2006-05-23 10:37:38 +00001905- Patch #876206: function call speedup by retaining allocated frame
1906 objects.
1907
Georg Brandl7b90e162006-05-18 07:01:27 +00001908- Bug #1462152: file() now checks more thoroughly for invalid mode
1909 strings and removes a possible "U" before passing the mode to the
1910 C library function.
1911
Neal Norwitz1004a532006-05-15 07:17:23 +00001912- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1913
Neal Norwitz373f0a72006-05-15 07:04:36 +00001914- Bug #1487966: Fix SystemError with conditional expression in assignment
1915
Martin v. Löwis879768d2006-05-11 13:28:43 +00001916- WindowsError now has two error code attributes: errno, which carries
1917 the error values from errno.h, and winerror, which carries the error
1918 values from winerror.h. Previous versions put the winerror.h values
1919 (from GetLastError()) into the errno attribute.
1920
Martin v. Löwis77736712006-05-04 05:51:03 +00001921- Patch #1475845: Raise IndentationError for unexpected indent.
1922
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001923- Patch #1479181: split open() and file() from being aliases for each other.
1924
Tim Peters44bd9862006-06-01 13:49:23 +00001925- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1926 methods were always silently ignored by dictionaries when comparing keys.
1927 They are now passed through (except when using the C API function
1928 ``PyDict_GetItem()``, whose semantics did not change).
1929
1930- Bug #1456209: In some obscure cases it was possible for a class with a
1931 custom ``__eq__()`` method to confuse dict internals when class instances
1932 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1933 No, you don't have any code that did this ;-)

1946
Nick Coghlanc649ec52006-05-29 12:43:05 +00001947- Patch #1478788 (modified version): The functional extension module has
1948 been renamed to _functools and a functools Python wrapper module added.
1949 This provides a home for additional function related utilities that are
1950 not specifically about functional programming. See PEP 309.
1951
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001952- Patch #1493701: performance enhancements for struct module.

1960 enabled builds on Windows and systems with Posix threads support.
1961
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001962- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1963 (up to the system limit of 32K characters).
1964
1965- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1966 As a result, these functions now raise WindowsError instead of OSError.
1967
Tim Peters7a822da2006-05-25 21:50:17 +00001968- ``time.clock()`` on Win64 should use the high-performance Windows
1969 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1970 Windows platforms).
1971
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001972- Calling Tk_Init twice is refused if the first call failed as that
1973 may deadlock.
1974
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001975- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1976 accept it without potentially using an uninitialized pointer.
1977
1978- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1979 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

1989 results. It could previously incorrectly return 0 in some cases.
1990 Fixes SF bug 1493322 (pybsddb bug 1184012).
1991
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001992- bsddb: the bsddb.dbtables Modify method now raises the proper error and

1994 Fixes SF python patch/bug #1408584.
1995
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001996- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00001997 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001998 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
1999 database calls that would previously deadlock. [SF python bug #775414]

Martin v. Löwis337487e2006-06-17 09:15:14 +00002019- Patch #763580: Add name and value arguments to Tkinter variable
2020 classes.
2021
Georg Brandl83cc0d02006-06-14 08:50:03 +00002022- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
2023 mime.types file for determining MIME types.
2024
Georg Brandl2605ca82006-06-14 06:08:31 +00002025- Bug #1339007: Shelf objects now don't raise an exception in their
2026 __del__ method when initialization failed.
2027
Martin v. Löwisd8251432006-06-14 05:21:04 +00002028- Patch #1455898: The MBCS codec now supports the incremental mode for
2029 double-byte encodings.
2030
Tim Peters43898b42006-06-14 04:09:25 +00002031- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
2032 guarantee that adjacent triples in the return list always describe
2033 non-adjacent blocks. Previously, a pair of matching blocks could end
2034 up being described by multiple adjacent triples that formed a partition
2035 of the matching pair.
2036
Greg Ward0e0c9f42006-06-11 16:24:11 +00002037- Bug #1498146: fix optparse to handle Unicode strings in option help,
2038 description, and epilog.
2039
Greg Wardd1c797e2006-06-11 14:42:41 +00002040- Bug #1366250: minor optparse documentation error.
2041
Greg Ward7f547402006-06-11 00:40:49 +00002042- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
2043 clarify docs.
2044
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00002045- The wsgiref package has been added to the standard library.
2046
Nick Coghlan676725d2006-06-08 13:54:49 +00002047- The functions update_wrapper() and wraps() have been added to the functools
2048 module. These make it easier to copy relevant metadata from the original
2049 function when writing wrapper functions.
2050
Tim Petersd6a9eef2006-06-05 01:48:21 +00002051- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
2052 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00002053
Martin v. Löwis3f767792006-06-04 19:36:28 +00002054- Patch #1359618: Speed up charmap encoder by using a trie structure
2055 for lookup.
2056
Tim Petersd609b1a2006-06-02 23:22:51 +00002057- The functions in the ``pprint`` module now sort dictionaries by key
2058 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
2059 if and only if its display required more than one line, although that
2060 wasn't documented. The new behavior increases predictability; e.g.,
2061 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
2062
Georg Brandlfd9a4b12006-05-29 20:57:01 +00002063- Patch #1497027: try HTTP digest auth before basic auth in urllib2
2064 (thanks for J. J. Lee).
2065
Georg Brandl2b330372006-05-28 20:23:12 +00002066- Patch #1496206: improve urllib2 handling of passwords with respect to
2067 default HTTP and HTTPS ports.
2068
George Yoshidaf3c65de2006-05-28 16:39:09 +00002069- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
2070
Bob Ippolito7298f272006-05-23 18:43:47 +00002071- Patch #1281707: speed up gzip.readline.
2072
Georg Brandlb89316f2006-05-17 15:51:16 +00002073- Patch #1180296: Two new functions were added to the locale module:
2074 format_string() to get the effect of "format % items" but locale-aware,
2075 and currency() to format a monetary number with currency sign.
2076
Georg Brandle3a25832006-05-17 14:56:04 +00002077- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
2078 and several features added, such as speed and geometry control.
2079
Georg Brandl49c8f4c2006-05-15 19:30:35 +00002080- Patch #1488881: add support for external file objects in bz2 compressed
2081 tarfiles.
2082
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002083- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
2084 stdout arguments, making it possible to redirect input and output
2085 for remote debugging.
2086
2087- Patch #1484695: Update the tarfile module to version 0.8. This fixes
2088 a couple of issues, notably handling of long file names using the
2089 GNU LONGNAME extension.
2090
2091- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
2092 new flag when ``name`` is already the name of an option flag.
2093
2094- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
2095 package.
2096
2097- Patch #1472854: make the rlcompleter.Completer class usable on non-
2098 UNIX platforms.
2099
2100- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
2101
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00002102- Bug #1472827: correctly escape newlines and tabs in attribute values in
2103 the saxutils.XMLGenerator class.

2138Core and builtins
2139-----------------
2140
Thomas Heller1b046642006-04-18 18:51:06 +00002141- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2142 by converting these apis from macros into exported functions again:
2143
2144 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2145 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2146 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
2147 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
2148 PyRun_String Py_CompileString
2149
Martin v. Löwis45294a92006-04-18 06:24:08 +00002150- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2151
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002152- All uses of PyStructSequence_InitType have been changed to initialize
2153 the type objects only once, even if the interpreter is initialized
2154 multiple times.
2155
Neal Norwitz61546162006-04-14 05:20:28 +00002156- Bug #1454485, array.array('u') could crash the interpreter. This was
2157 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2158 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2159
2160- Py_UNICODE is unsigned. It was always documented as unsigned, but
2161 due to a bug had a signed value in previous versions.
2162
Tim Peters3a5e8b12006-04-11 01:44:07 +00002163- Patch #837242: ``id()`` of any Python object always gives a positive
2164 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2165 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002166 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002167 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002168
Tim Peters3a5e8b12006-04-11 01:44:07 +00002169 def __hash__(self):
2170 return id(self) # WRONG
2171
2172 because a hash result must be a (short) Python int but it was always
2173 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002174 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002175 was always usable as a hash value before this patch. That's no longer
2176 necessarily so.
2177
2178- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002179 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002180 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002181 #1454844)
2182
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002183- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2184 involving generators that have paused outside of any ``try`` or ``with``
2185 blocks. (In 2.5a1, a paused generator that was part of a reference
2186 cycle could not be garbage collected, regardless of whether it was
2187 paused in a ``try`` or ``with`` block.)

2201 the cachesize parameter.
2202
2203- Bug #1149413: bsddb.*open() no longer raises an exception when using
2204 a temporary db (file=None) with the 'n' flag to truncate on open.

2206- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
2207 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00002208
Armin Rigoa9017c32006-04-19 11:50:27 +00002209- Patch #1062014: AF_UNIX sockets under Linux have a special

2217 abusing errno.
2218
Tim Peters711bf302006-04-25 03:31:36 +00002219- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2220 a doctest to be skipped (the code is not run, and the expected output
2221 or exception is ignored).
2222
Nick Coghlanda2268f2006-04-24 04:37:15 +00002223- Fixed contextlib.nested to cope with exceptions being raised and
2224 caught inside exit handlers.
2225
Greg Wardab05edc2006-04-23 03:47:58 +00002226- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2227 hex, octal, or binary; add ``append_const`` action; keep going if
2228 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2229 added ``epilog`` for better help generation).
2230
Tim Peters21fbd572006-04-21 21:18:10 +00002231- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2232 called from a thread spawned as a side effect of importing a module.
2233
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002234- The pydoc module now supports documenting packages contained in
2235 .zip or .egg files.
2236
2237- The pkgutil module now has several new utility functions, such
2238 as ``walk_packages()`` to support working with packages that are either
2239 in the filesystem or zip files.
2240
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002241- The mailbox module can now modify and delete messages from
2242 mailboxes, in addition to simply reading them. Thanks to Gregory
2243 K. Johnson for writing the code, and to the 2005 Google Summer of
2244 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002245
Tim Petersc7605f22006-04-17 21:12:33 +00002246- The ``__del__`` method of class ``local`` in module ``_threading_local``
2247 returned before accomplishing any of its intended cleanup.
2248
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002249- Patch #790710: Add breakpoint command lists in pdb.

Anthony Baxtere29002c2006-04-12 12:07:31 +00002255- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
2256 Windows. Bug #1469163.
2257
Phillip J. Eby47032112006-04-11 01:07:43 +00002258- The warnings, linecache, inspect, traceback, site, and doctest modules
2259 were updated to work correctly with modules imported from zipfiles or
2260 via other PEP 302 __loader__ objects.
2261

Martin v. Löwis4be4e652006-04-17 19:25:49 +00002275- The Makefile now has a reindent target, which runs reindent.py on
2276 the library.

2283 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002284 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002285 CXX from --with-cxx-main, see description in README.
2286

2290
Tim Peters8931ff12006-05-13 23:28:20 +00002291- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2292 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,

2294
Anthony Baxter51bcb682006-04-05 14:51:42 +00002295Tests

2297
Nick Coghlanda2268f2006-04-24 04:37:15 +00002298- test_contextlib now checks contextlib.nested can cope with exceptions
2299 being raised and caught inside exit handlers.
2300
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002301- test_cmd_line now checks operation of the -m and -c command switches
2302
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002303- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2304 it separately and by hand. It also wasn't cleaning up its changes to
2305 the current Decimal context.
2306
Thomas Woutersabd08882006-04-26 15:53:30 +00002307- regrtest.py now has a -M option to run tests that test the new limits of
2308 containers, on 64-bit architectures. Running these tests is only sensible
2309 on 64-bit machines with more than two gigabytes of memory. The argument
2310 passed is the maximum amount of memory for the tests to use.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002331What's New in Python 2.5 alpha 1?
2332=================================
2333
Anthony Baxterebed3f62006-04-03 15:03:44 +00002334*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002335
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002336Core and builtins
2337-----------------
2338
Nick Coghlan43832302006-04-23 17:04:07 +00002339- PEP 338: -m command line switch now delegates to runpy.run_module
2340 allowing it to support modules in packages and zipfiles
2341
Martin v. Löwisc661b882006-04-20 04:54:23 +00002342- On Windows, .DLL is not an accepted file name extension for
2343 extension modules anymore; extensions are only found if they
2344 end in .PYD.
2345
Martin v. Löwisea62d252006-04-03 10:56:49 +00002346- Bug #1421664: sys.stderr.encoding is now set to the same value as
2347 sys.stdout.encoding.
2348
Neal Norwitz92e212f2006-04-03 04:48:37 +00002349- __import__ accepts keyword arguments.
2350
Georg Brandlccadf842006-03-31 18:54:53 +00002351- Patch #1460496: round() now accepts keyword arguments.
2352
Anthony Baxter262c00a2006-03-30 10:53:17 +00002353- Fixed bug #1459029 - unicode reprs were double-escaped.
2354
Hye-Shik Changd478f342006-03-23 12:32:36 +00002355- Patch #1396919: The system scope threads are reenabled on FreeBSD
2356 5.4 and later versions.
2357
Neal Norwitze98ccf62006-03-23 05:39:47 +00002358- Bug #1115379: Compiling a Unicode string with an encoding declaration
2359 now gives a SyntaxError.
2360
Georg Brandlabd1ff82006-03-18 07:59:59 +00002361- Previously, Python code had no easy way to access the contents of a
2362 cell object. Now, a ``cell_contents`` attribute has been added
2363 (closes patch #1170323).
2364
Tim Peterscf79aac2006-03-16 01:14:46 +00002365- Patch #1123430: Python's small-object allocator now returns an arena to
2366 the system ``free()`` when all memory within an arena becomes unused
2367 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2368 freed. Some applications will see a drop in virtual memory size now,
2369 especially long-running applications that, from time to time, temporarily
2370 use a large number of small objects. Note that when Python returns an
2371 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002372 platform C library will in turn return that memory to the operating system.
2373 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002374 appears to be effective at least on Microsoft C and gcc-based systems.
2375 Thanks to Evan Jones for hard work and patience.
2376
Georg Brandl533ff6f2006-03-08 18:09:27 +00002377- Patch #1434038: property() now uses the getter's docstring if there is
2378 no "doc" argument given. This makes it possible to legitimately use
2379 property() as a decorator to produce a read-only property.
2380
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002381- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2382 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2383 of requiring an int or long in slicing and a few other contexts, enabling
2384 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2385
Neal Norwitz995acdf2006-03-07 05:01:00 +00002386- Fixed various bugs reported by Coverity's Prevent tool.
2387
Brett Cannonbf364092006-03-01 04:25:17 +00002388- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2389 new exception base class, BaseException, which has a new message attribute.
2390 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2391 Raising a string exception now raises a DeprecationWarning.
2392
Thomas Woutersfb609f42006-02-28 16:37:25 +00002393- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2394 explicitly relative, using 'from .module import name' to mean 'from the same
2395 package as this module is in. Imports without dots still default to the
2396 old relative-then-absolute, unless 'from __future__ import
2397 absolute_import' is used.
2398
Brett Cannona7446e32006-02-27 23:39:10 +00002399- Properly check if 'warnings' raises an exception (usually when a filter set
2400 to "error" is triggered) when raising a warning for raising string
2401 exceptions.
2402
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002403- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002404 The name was removed from Include/code.h.
2405
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002406- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002407
Guido van Rossum1968ad32006-02-25 22:38:04 +00002408- Patch 1433928:
2409 - The copy module now "copies" function objects (as atomic objects).
2410 - dict.__getitem__ now looks for a __missing__ hook before raising
2411 KeyError.
2412
Tim Peters84ef21c2006-02-28 20:39:06 +00002413- PEP 343: with statement implemented. Needs ``from __future__ import
2414 with_statement``. Use of 'with' as a variable will generate a warning.
2415 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002416 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002417 The following objects have __context__ methods:
2418 - The built-in file type.
2419 - The thread.LockType type.
2420 - The following types defined by the threading module:
2421 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2422 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002423
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002424- Fix the encodings package codec search function to only search
2425 inside its own package. Fixes problem reported in patch #1433198.
2426
2427 Note: Codec packages should implement and register their own
2428 codec search function. PEP 100 has the details.
2429
Tim Peters9ea89d22006-06-04 03:26:02 +00002430- PEP 353: Using ``Py_ssize_t`` as the index type.
2431
2432- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2433 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2434 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2435 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2436 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002437
Neal Norwitzfc76d632006-01-10 06:03:13 +00002438- Patch #1400181, fix unicode string formatting to not use the locale.
2439 This is how string objects work. u'%f' could use , instead of .
2440 for the decimal point. Now both strings and unicode always use periods.
2441
Neal Norwitz671b9e32006-01-09 07:07:12 +00002442- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2443 configure would break checking curses.h.
2444
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002445- Bug #959576: The pwd module is now builtin. This allows Python to be
2446 built on UNIX platforms without $HOME set.
2447
Neal Norwitzc10978f2005-12-19 06:07:16 +00002448- Bug #1072182, fix some potential problems if characters are signed.
2449
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002450- Bug #889500, fix line number on SyntaxWarning for global declarations.
2451
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002452- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2453
Neal Norwitze7214a12005-12-18 05:03:17 +00002454- Support for converting hex strings to floats no longer works.
2455 This was not portable. float('0x3') now raises a ValueError.
2456
Barry Warsaw2a38a862005-12-18 01:27:35 +00002457- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002458 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002459 is now displayed in interactive prompt banner.
2460
Georg Brandlfa166682005-12-17 21:45:17 +00002461- Implementation of PEP 341 - Unification of try/except and try/finally.
2462 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002463 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002464
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002465- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2466 now encodes backslash correctly.
2467
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002468- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2469
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002470- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002471 and long longs.
2472
Neal Norwitz67715f02005-11-09 06:59:35 +00002473- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002474 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002475 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002476
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002477- Replaced most Unicode charmap codecs with new ones using the
2478 new Unicode translate string feature in the builtin charmap
2479 codec; the codecs were created from the mapping tables available
2480 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2481 encodings now include a mapping for the Apple logo)
2482
Tim Peterse3547fd2005-12-16 23:13:57 +00002483- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002484
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002485- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002486
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002487- A new AST parser implementation was completed. The abstract
2488 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002489 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002490
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002491- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002492 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2493
Neal Norwitz708e51a2005-10-03 04:48:15 +00002494- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2495
Neal Norwitz11bd1192005-10-03 00:54:56 +00002496- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2497 Provide a warning when a directory is passed on the command line.
2498
Neal Norwitz40d37812005-10-02 01:48:49 +00002499- Fix segfault with invalid coding.
2500
2501- SF bug #772896: unknown encoding results in MemoryError.
2502
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002503- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002504 supported a __len__() method which evaluated to False when the iterator
2505 was empty.
2506
Guido van Rossum630db602005-09-20 18:49:54 +00002507- On 64-bit platforms, when __len__() returns a value that cannot be
2508 represented as a C int, raise OverflowError.
2509
Skip Montanarof8948ca2005-09-19 03:54:46 +00002510- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002511 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002512
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002513- SF bug #893549: parsing keyword arguments was broken with a few format
2514 codes.
2515
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002516- Changes donated by Elemental Security to make it work on AIX 5.3
2517 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2518 bug #105470: test_pwd fails on 64bit system (Opteron).
2519
Guido van Rossum539c6622005-09-14 17:49:54 +00002520- Changes donated by Elemental Security to make it work on HP-UX 11 on
2521 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2522
Georg Brandl4550b8d2005-08-26 06:43:52 +00002523- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002524 (fixes bug #1119418).
2525
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002526- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2527
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002528- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2529 exceptions that cause a function to exit.
2530
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002531- The implementation of set() and frozenset() was revised to use its
2532 own internal data structure. Memory consumption is reduced by 1/3
2533 and there are modest speed-ups as well. The API is unchanged.
2534
Tim Petersde7990b2005-07-17 23:45:23 +00002535- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2536
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002537- SF bug #1229429: PyObject_CallMethod failed to decrement some
2538 reference counts in some error exit cases.
2539
Tim Petersecc6e6a2005-07-10 22:30:55 +00002540- SF bug #1185883: Python's small-object memory allocator took over
2541 a block managed by the platform C library whenever a realloc specified
2542 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002543 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002544 portable way to copy data from the C-managed block into Python's
2545 small-object space without risking a memory fault. Python's small-object
2546 realloc now leaves such blocks under the control of the platform C
2547 realloc.
2548
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002549- SF bug #1232517: An overflow error was not detected properly when
2550 attempting to convert a large float to an int in os.utime().
2551
Raymond Hettinger3296e692005-06-29 23:29:56 +00002552- SF bug #1224347: hex longs now print with lowercase letters just
2553 like their int counterparts.
2554
Michael W. Hudson188d4362005-06-20 16:52:57 +00002555- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2556 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2557 interpreter states; back out that fix and do a better job (see
2558 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2559 for a longer write-up of the problem).
2560
Michael W. Hudsondf888462005-06-03 14:41:55 +00002561- SF patch #1180995: marshal now uses a binary format by default when
2562 serializing floats.
2563
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002564- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2565 the routines that promise to produce IEEE 754 binary representations
2566 of floats now simply copy bytes around.
2567
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002568- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2569 278.
2570
Brett Cannonc3647ac2005-04-26 03:45:26 +00002571- patch #1109424: int, long, float, complex, and unicode now check for the
2572 proper magic slot for type conversions when subclassed. Previously the
2573 magic slot was ignored during conversion. Semantics now match the way
2574 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002575 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002576 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002577 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002578
Barry Warsawc8d907c2005-04-19 23:43:40 +00002579- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2580 NULL, now raise an AttributeError when attempting to set or delete the
2581 attribute. Previously a TypeError was raised, but this was inconsistent
2582 with the equivalent pure-Python implementation.
2583
Michael W. Hudson774479c2005-04-18 08:46:17 +00002584- It is now safe to call PyGILState_Release() before
2585 PyEval_InitThreads() (note that if there is reason to believe there
2586 are multiple threads around you still must call PyEval_InitThreads()
2587 before using the Python API; this fix is for extension modules that
2588 have no way of knowing if Python is multi-threaded yet).
2589
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002590- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2591 disabled caused a crash.
2592
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002593- Bug #1165306: instancemethod_new allowed the creation of a method
2594 with im_class == im_self == NULL, which caused a crash when called.

2642 current thread state when the auto-GIL-state machinery knows about
2643 it (since the thread state is being deleted, continuing to remember it
2644 can't help, but can hurt if another thread happens to get created with
2645 the same thread id).

Anthony Baxterc51ee692006-04-01 00:57:31 +00002855- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002856 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or

Tim Petersc17976e2006-04-01 00:26:53 +00002860- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2861 aren't officially supported here, and trying to use them will probably
2862 raise an exception some day. But dicts have been allowed, and "mostly
2863 worked", so support for them won't go away without warning.
2864
Georg Brandl338ef7d2006-03-31 18:42:16 +00002865- Bug #1445068: getpass.getpass() can now be given an explicit stream

Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002876- Queue.Queue objects now support .task_done() and .join() methods
2877 to make it easier to monitor when daemon threads have completed
2878 processing all enqueued tasks. Patch #1455676.
2879
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002880- popen2.Popen objects now preserve the command in a .cmd attribute.

2883
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002884- email 4.0 package now integrated. This is largely the same as the email 3.0
2885 package that was included in Python 2.3, except that PEP 8 module names are
2886 now used (e.g. mail.message instead of email.Message). The MIME classes
2887 have been moved to a subpackage (e.g. email.mime.text instead of
2888 email.MIMEText). The old names are still supported for now. Several
2889 deprecated Message methods have been removed and lots of bugs have been
2890 fixed. More details can be found in the email package documentation.
2891
Walter Dörwald40108c92006-03-27 08:15:44 +00002892- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2893 (a subclass of tuple) that provides incremental decoders and encoders
2894 (a way to use stateful codecs without the stream API). Python functions
2895 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2896 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2897 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002898
Walter Dörwald067db482006-03-15 22:17:27 +00002899- Patch #1359365: Calling next() on a closed StringIO.String object raises
2900 a ValueError instead of a StopIteration now (like file and cString.String do).
2901 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2902 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002903
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002904- A regrtest option -w was added to re-run failed tests in verbose mode.

2910 grew an optional 'generation' argument.
2911
Martin v. Löwisfbab90e2006-03-05 13:36:04 +00002912- A library msilib to generate Windows Installer files, and a distutils

2972 LoadError as documented, instead of IOError. For compatibility,
2973 LoadError subclasses IOError.

Tim Peterse3547fd2005-12-16 23:13:57 +00002976 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2977 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2978 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2979 Ronald L. Rivest offered this advice for Python:
2980
2981 "The consensus of researchers in this area (at least as
2982 expressed at the NIST Hash Function Workshop 10/31/05),
2983 is that SHA-256 is a good choice for the time being, but
2984 that research should continue, and other alternatives may
2985 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002986
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002987- Added a subset of Fredrik Lundh's ElementTree package. Available

3145
Guido van Rossumd0641422005-02-03 15:01:24 +00003146- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
3147 disables recursive traversal through instance attributes, which can
3148 be exploited in various ways.
3149
Tim Peterse3547fd2005-12-16 23:13:57 +00003150- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00003151 flags on the HTTP listening socket.
3152
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00003153- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
3154 Fixed by reading the HTTP body in chunks instead of one big socket.read().
3155
Fred Drakefbdeaad2006-07-29 16:56:15 +00003156- Patches #893642, #1039083: add allow_none, encoding arguments to

3162
Martin v. Löwis22b457e2005-01-16 08:40:58 +00003163- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
3164
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003165- Enhancements to the csv module:
3166
3167 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003168 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003169 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003170 + Dialect parameter parsing has been re-implemented to improve error
3171 reporting.
3172 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3173 dictates.
3174 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003175 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003176 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003177 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3178 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003179 + reader now allows \r characters to be quoted (previously it only allowed
3180 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003181 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003182 + Dialect classes passed to the module are no longer instantiated by
3183 the module before being parsed (the former validation scheme required
3184 this, but the mechanism was unreliable).
3185 + The dialect registry now contains instances of the internal
3186 C-coded dialect type, rather than references to python objects.
3187 + the internal c-coded dialect type is now immutable.
3188 + register_dialect now accepts the same keyword dialect specifications
3189 as the reader and writer, allowing the user to register dialects
3190 without first creating a dialect class.
3191 + a configurable limit to the size of parsed fields has been added -
3192 previously, an unmatched quote character could result in the entire
3193 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003194 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003195 the parser field size limit (returning the former limit). The initial
3196 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003197 + A line_num attribute has been added to the reader object, which tracks
3198 the number of lines read from the source iterator. This is not
3199 the same as the number of records returned, as records can span
3200 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003201 + reader and writer objects were not being registered with the cyclic-GC.
3202 This has been fixed.
3203
Brett Cannone6539c42005-01-08 02:43:53 +00003204- _DummyThread objects in the threading module now delete self.__block that is
3205 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3206 lock primitives tend to be limited in number and thus should not be wasted on
3207 a _DummyThread object. Fixes bug #1089632.
3208
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003209- The imghdr module now detects Exif files.
3210
Raymond Hettinger6065d322004-12-20 23:51:53 +00003211- StringIO.truncate() now correctly adjusts the size attribute.
3212 (Bug #951915).
3213
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003214- locale.py now uses an updated locale alias table (built using
3215 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3216 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003217 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003218
Raymond Hettinger3557f422004-12-07 12:02:02 +00003219- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3220
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003221- the pickle module no longer accepts the deprecated None option in the
3222 args tuple returned by __reduce__().
3223
Brett Cannon84667c02004-12-07 03:25:18 +00003224- optparse now optionally imports gettext. This allows its use in setup.py.
3225
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003226- the pickle module no longer uses the deprecated bin parameter.
3227
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003228- the shelve module no longer uses the deprecated binary parameter.
3229
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003230- the pstats module no longer uses the deprecated ignore() method.
3231
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003232- the filecmp module no longer uses the deprecated use_statcache argument.
3233
Raymond Hettinger664347b2004-12-04 21:21:53 +00003234- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3235 extended or overridden by subclasses. Formerly, the subclassed method would
3236 be ignored by the rest of the module. (Bug #1078905).
3237
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003238- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003239 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003240
Walter Dörwald36733692004-12-22 12:50:50 +00003241- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3242 once when a size argument is given. This prevents a buffer overflow in the
3243 tokenizer with very long source lines.
3244
Barry Warsaw538561e2006-01-01 21:48:54 +00003245- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3246 immediately after creating the object, without any intervening
3247 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003248
Skip Montanaro05885812005-01-16 20:48:27 +00003249- The reconvert.quote function can now emit triple-quoted strings. The
3250 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003251
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003252- ``UserString.MutableString`` now supports negative indices in
3253 ``__setitem__`` and ``__delitem__``
3254
Greg Ward40407942005-03-05 02:53:17 +00003255- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3256 correctly.
3257
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003258- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3259 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3260 character even if the user has passed a size parameter to get a proper
3261 line ending. Remove the special handling of a "\r\n" that has been split
3262 between two lines.
3263
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003264- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3265 about illegal code points. The codec now supports PEP 293 style error
3266 handlers.
3267
Walter Dörwald78a78b02005-09-01 12:04:29 +00003268- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003269 from the input stream, so that the output is a byte string in the correct
3270 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003271
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003272- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3273 considering it exactly like a '*'.
3274
Walter Dörwald007f8df2005-10-09 19:42:27 +00003275- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3276 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003277
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003278- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3279
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003280- Patch #1413711: Certain patterns of differences were making difflib
3281 touch the recursion limit.
3282
Walter Dörwald58917a62006-03-31 15:26:22 +00003283- Bug #947906: An object oriented interface has been added to the calendar
3284 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003285 called as a script (e.g. via ``python -mcalendar``). Localized month and
3286 weekday names can be ouput (even if an exotic encoding is used) using
3287 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003288
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003289Build
3290-----
3291
Neal Norwitz602d3392006-03-31 08:21:40 +00003292- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3293 by using -mieee gcc option.
3294
Martin v. Löwis86d66262006-02-17 08:40:11 +00003295- Patch #1432345: Make python compile on DragonFly.
3296
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003297- Build support for Win64-AMD64 was added.
3298
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003299- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3300
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003301- Patch #881820: look for openpty and forkpty also in libbsd.
3302
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003303- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3304 The zlib module is now builtin on Windows.
3305
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003306- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3307
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003308- Bug #1189330: configure did not correctly determine the necessary
3309 value of LINKCC if python was built with GCC 4.0.
3310
Trent Mick8321b422005-07-26 02:29:21 +00003311- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3312 vulnerability in zlib 1.2.1 and 1.2.2.
3313
Brett Cannon08cd5982005-04-24 22:26:38 +00003314- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3315 flags that change binary compatibility. Changes were also made to
3316 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003317 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003318
Bob Ippolitoed233462005-03-29 13:47:59 +00003319- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3320 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3321 no longer exists). This configure patch makes things right.
3322
Martin v. Löwise2713be2005-03-08 15:03:08 +00003323- Bug #1158607: Build with --disable-unicode again.
3324
Brett Cannon46d96232005-02-16 00:07:19 +00003325- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3326 defined. Discovered as a result of not being able to build on OS X.
3327
Brett Cannon516592f2004-12-07 00:42:59 +00003328- setup.py now uses the directories specified in LDFLAGS using the -L option
3329 and in CPPFLAGS using the -I option for adding library and include
3330 directories, respectively, for compiling extension modules against. This has
3331 led to the core being compiled using the values in CPPFLAGS. It also removes
3332 the need for the special-casing of both DarwinPorts and Fink for darwin since
3333 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3334 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3335 Fink, ``-I/opt/local/include`` for DarwinPorts).
3336
Brett Cannon43802422005-02-10 20:48:03 +00003337- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3338 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3339 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3340 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003342C API
3343-----
3344
Tim Petersc9d78aa2006-03-26 23:27:58 +00003345- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3346 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3347 is obtained via the ``PyObject_`` family, it must be released via the
3348 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3349 always been officially true, but when Python's small-object allocator was
3350 introduced, an attempt was made to cater to a few extension modules
3351 discovered at the time that obtained memory via ``PyObject_New`` but
3352 released it via ``PyMem_DEL``. It's years later, and if such code still
3353 exists it will fail now (probably with segfaults, but calling wrong
3354 low-level memory management functions can yield many symptoms).
3355
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003356- Added a C API for set and frozenset objects.
3357
Raymond Hettinger66517482004-12-03 11:45:13 +00003358- Removed PyRange_New().
3359
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003360- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3361 mapping argument now. This string is used as a mapping table. Byte values
3362 greater than the length of the string and 0xFFFE are treated as undefined
3363 mappings.
