92 set to a custom object whose write() method happens to install
93 another file in sys.stdout.
94
Amaury Forgeot d'Arcb15bdf72008-07-01 20:59:49 +000095- Issue #3088: Corrected a race condition in classes derived from

101
Guido van Rossumaa975432008-04-10 22:43:58 +0000102- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
103 having a self-referential tuple, which is possible from C code. Nor did
104 object's tp_str consider that a type's tp_str could do something that could
105 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
106 respectively, fixed the issues. (Backport of r58288 from trunk.)

115 \Uxxxxxxxx did not accept values outside the Basic Multilingual Plane. This
116 affected raw unicode literals and the 'raw-unicode-escape' codec. Now
117 UTF-16 surrogates are generated in this case, like normal unicode literals
118 and the 'unicode-escape' codec.
119
Neal Norwitzb3635f92008-03-18 04:17:36 +0000120- Issue #2321: use pymalloc for unicode object string data to reduce
121 memory usage in some circumstances.
Andrew M. Kuchlingbe0adfc2008-02-23 17:18:19 +0000122
Sean Reifscheider4af861c2008-03-20 17:39:31 +0000123- Issue #2238: Some syntax errors in *args and **kwargs expressions could give

127 parameter but was not verifying that it was greater than zero. Values
128 less than zero will now raise a SystemError and return NULL to indicate a
129 bug in the calling C code.
130
Gregory P. Smith9aa040d2008-06-02 00:07:25 +0000131- Issue #2588, #2589: Fix potential integer underflow and overflow
132 conditions in the PyOS_vsnprintf C API function.
133
Gregory P. Smithcae7f882008-09-07 06:44:12 +0000134- Issue #1204: The configure script now tests for additional libraries
135 that may be required when linking against readline. This fixes issues
136 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
Georg Brandld9f1da02008-03-29 01:50:46 +0000137
Gregory P. Smitha7a94a02008-09-22 00:22:44 +0000138- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
139 library targets in the Makefile.

175 error when they failed.
176
Amaury Forgeot d'Arc22679b82008-08-18 19:33:42 +0000177- Issue #2234: distutils failed for some versions of the cygwin compiler. The
178 version reported by these tools does not necessarily follow the python
179 version numbering scheme, so the module is less strict when parsing it.
180
Hirokazu Yamamoto1d63a452008-08-17 09:49:10 +0000181- Issue #2222: Fixed reference leak when occured os.rename()

1165-----------------
1166
Neal Norwitz0bcafac2006-09-11 08:51:17 +00001167- Make _PyGILState_NoteThreadState() static, it was not used anywhere
1168 outside of pystate.c and should not be necessary.
1169
Brett Cannon19d76c52006-09-09 07:18:44 +00001170- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
1171 allows calling unicode() on exceptions classes directly to succeed.
1172
Georg Brandlecab6232006-09-06 06:47:02 +00001173- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
1174 Also make sure that every exception class has __module__ set to
1175 'exceptions'.
1176
Georg Brandl37a9e572006-09-06 06:09:34 +00001177- Bug #1550983: emit better error messages for erroneous relative
1178 imports (if not in package and if beyond toplevel package).
1179
Tim Peterscbdd3502006-09-05 01:47:53 +00001180- Overflow checking code in integer division ran afoul of new gcc
1181 optimizations. Changed to be more standard-conforming.

1187
Neal Norwitz29a5fdb2006-09-05 02:21:38 +00001188- The return tuple from str.rpartition(sep) is (tail, sep, head) where
1189 head is the original string if sep was not found.
1190
Neal Norwitz3b3aae02006-09-05 03:56:01 +00001191- Bug #1520864: unpacking singleton tuples in list comprehensions and
1192 generator expressions (x for x, in ... ) works again. Fixing this problem
1193 required changing the .pyc magic number. This means that .pyc files
1194 generated before 2.5c2 will be regenerated.

Guido van Rossumc69ac252006-08-10 18:09:25 +00001301What's New in Python 2.5 release candidate 1?
1302=============================================
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001303
Anthony Baxterb4096662006-08-16 03:42:26 +00001304*Release date: 17-AUG-2006*

1306Core and builtins
1307-----------------
1308
Neal Norwitz24b6f202006-09-05 04:43:56 +00001309- Fix infinite recursion when subclassing long and overriding __hash__.
1310
1311- Fix concatenation (+=) of long strings.
1312
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001313- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001314 compared equal or unequal to a string and a UnicodeDecodeError
1315 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001316
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001317 Instead, the equal (==) and unequal (!=) comparison operators will
1318 now issue a UnicodeWarning and interpret the two objects as
1319 unequal. The UnicodeWarning can be filtered as desired using
1320 the warning framework, e.g. silenced completely, turned into an
1321 exception, logged, etc.
1322
1323 Note that compare operators other than equal and unequal will still
1324 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001325
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001326- Fix segfault when doing string formatting on subclasses of long.
1327
1328- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1329 with new-style classes.
1330
1331- Fix bug related to __len__ functions returning negative values with
1332 classic classes.
1333
1334- Patch #1538606, Fix __index__() clipping. There were some problems
1335 discovered with the API and how integers that didn't fit into Py_ssize_t
1336 were handled. This patch attempts to provide enough alternatives
1337 to effectively use __index__.
1338
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001339- Bug #1536021: __hash__ may now return long int; the final hash
1340 value is obtained by invoking hash on the long int.
1341
Thomas Hellerab1049c2006-08-08 17:37:00 +00001342- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1343
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001344- Bug #1535165: fixed a segfault in input() and raw_input() when
1345 sys.stdin is closed.
1346
Thomas Heller74d36f02006-08-04 18:17:40 +00001347- On Windows, the PyErr_Warn function is now exported from
1348 the Python dll again.
1349
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001350- Bug #1191458: tracing over for loops now produces a line event
1351 on each iteration. Fixing this problem required changing the .pyc
1352 magic number. This means that .pyc files generated before 2.5c1
1353 will be regenerated.
1354
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001355- Bug #1333982: string/number constants were inappropriately stored
1356 in the byte code and co_consts even if they were not used, ie
1357 immediately popped off the stack.
1358
Georg Brandle9462c72006-08-04 18:03:37 +00001359- Fixed a reference-counting problem in property().

1362Library
1363-------
1364
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001365- Fix a bug in the ``compiler`` package that caused invalid code to be
1366 generated for generator expressions.
1367
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001368- The distutils version has been changed to 2.5.0. The change to
1369 keep it programmatically in sync with the Python version running
1370 the code (introduced in 2.5b3) has been reverted. It will continue
1371 to be maintained manually as static string literal.
1372
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001373- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001374 and this cannot be converted to the required C type, an exception is
1375 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001376 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001377
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001378- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001379 an exception.
1380
Tim Peterscbdd3502006-09-05 01:47:53 +00001381- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001382 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001383 workarounds for clocks with low resolution, to stop the code yielding
1384 duplicate UUIDs.
1385
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001386- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1387 before raising SystemExit, allowing IDLE to honor quit() and exit().
1388
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001389- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1390
Georg Brandl7a1af772006-08-14 21:55:28 +00001391- Patch #1536071: trace.py should now find the full module name of a
1392 file correctly even on Windows.
1393
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001394- logging's atexit hook now runs even if the rest of the module has
1395 already been cleaned up.
1396
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001397- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001398
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001399- Bug #1531405, format_exception no longer raises an exception if
1400 str(exception) raised an exception.
1401
Neil Schemenauer06ded092006-08-04 16:20:30 +00001402- Fix a bug in the ``compiler`` package that caused invalid code to be
1403 generated for nested functions.

1414 raises the correct exceptions.
1415
Thomas Heller1ce433e2006-08-14 16:20:04 +00001416- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1417 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1418
Thomas Heller86720042006-08-14 11:17:48 +00001419- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1420 uses the _as_parameter_ attribute when objects are passed to foreign
1421 function calls. The ctypes version number was changed to 1.0.1.
1422
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001423- Bug #1530559, struct.pack raises TypeError where it used to convert.
1424 Passing float arguments to struct.pack when integers are expected
1425 now triggers a DeprecationWarning.

Martin v. Löwisa09fd6e2006-08-16 12:55:10 +00001451- Bug #1535502, build _hashlib on Windows, and use masm assembler
1452 code in OpenSSL.
1453
Thomas Hellerdb7b4432006-08-04 19:49:31 +00001454- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.
1455
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001456- Bug #1530448, ctypes build failure on Solaris 10 was fixed.

Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001462- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1463
Tim Peters4643c2f2006-08-10 22:45:34 +00001464- Bug #1069160. Internal correctness changes were made to
1465 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1466 the documentation was changed to state that the return value
1467 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001470What's New in Python 2.5 beta 3?
1471================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001472
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001473*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001474
1475Core and builtins
1476-----------------
1477
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001478- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001479 returned a long (see PEP 353).
1480
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001481- Bug #1515471: string.replace() accepts character buffers again.
1482
Neal Norwitz07aadb12006-07-30 06:55:48 +00001483- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1484 This provides the proper warning for struct.pack().
1485 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1486
Neal Norwitz0d62a062006-07-30 06:53:31 +00001487- Patch #1531113: Fix augmented assignment with yield expressions.
1488 Also fix a SystemError when trying to assign to yield expressions.
1489
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001490- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1491 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1492 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1493 excessive filesystem operations during imports.
1494
Tim Petersbc24eee2006-07-27 01:14:53 +00001495- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1496 operations on signed longs that are formally undefined by C.
1497 Unfortunately, at least one compiler now cares about that, so complicated
1498 the code to make that compiler happy again.
1499
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001500- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1501
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001502- Patch #1232023: Stop including current directory in search
1503 path on Windows.
1504
Neal Norwitze1fdb322006-07-21 05:32:28 +00001505- Fix some potential crashes found with failmalloc.
1506
Neal Norwitze7563102006-07-17 01:00:16 +00001507- Fix warnings reported by Klocwork's static analysis tool.
1508
Neal Norwitz84be93b2006-07-16 01:50:38 +00001509- Bug #1512814, Fix incorrect lineno's when code within a function
1510 had more than 255 blank lines.
1511
Georg Brandl9dceedb2006-07-12 15:31:17 +00001512- Patch #1521179: Python now accepts the standard options ``--help`` and
1513 ``--version`` as well as ``/?`` on Windows.
1514
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001515- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001516 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001517 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001518
Tim Peters112aad32006-07-19 00:03:19 +00001519- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001520 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001521 new ``sys._current_frames()`` returns a dictionary with one entry,
1522 mapping the faux "thread id" 0 to the current frame.
1523
Ronald Oussoren3075e162006-07-25 20:28:55 +00001524- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001525

1528-------
1529
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001530- Correction of patch #1455898: In the mbcs decoder, set final=False
1531 for stream decoder, but final=True for the decode function.
1532
Georg Brandl07fec3a2006-08-01 18:49:24 +00001533- os.urandom no longer masks unrelated exceptions like SystemExit or
1534 KeyboardInterrupt.
1535
Tim Peters4643c2f2006-08-10 22:45:34 +00001536- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001537 shutil.copytree on Windows
1538
Georg Brandle34ac7c2006-07-30 11:07:23 +00001539- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1540 refers to file descriptors, not file objects.
1541
Tim Peterscbdd3502006-09-05 01:47:53 +00001542- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001543 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001544 #1513611, and probably others.
1545
Georg Brandledd9b0d2006-07-29 09:33:26 +00001546- Bug #1441397: The compiler module now recognizes module and function
1547 docstrings correctly as it did in Python 2.4.
1548
Tim Peters6f681472006-07-27 23:44:37 +00001549- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1550 lost that tests are sorted by name before being run. This rarely
1551 matters for well-written tests, but can create baffling symptoms if
1552 side effects from one test to the next affect outcomes. ``DocTestFinder``
1553 has been changed to sort the list of tests it returns.
1554
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001555- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001556 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001557
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001558- Bug #978833: Really close underlying socket in _socketobject.close.
1559
Georg Brandldb232dc2006-08-20 13:15:43 +00001560- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1561 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001562
Georg Brandlcf0c1722006-07-26 07:23:32 +00001563- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1564 to recursive calls and call it with the failing package name.
1565
Martin v. Löwis0b483032006-07-25 09:53:12 +00001566- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1567
Georg Brandlc13c34c2006-07-24 14:09:56 +00001568- Patch #1515343: Fix printing of deprecated string exceptions with a
1569 value in the traceback module.
1570
Greg Ward48fae7a2006-07-23 16:05:51 +00001571- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1572
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001573- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1574
Brett Cannoncaebe222006-07-18 04:41:36 +00001575- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1576 argument tuple. For arguments where zero is illegal, the value is forced to
1577 the minimum value that is correct. This is to support an undocumented but
1578 common way people used to fill in inconsequential information in the time
1579 tuple pre-2.4.
1580
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001581- Patch #1220874: Update the binhex module for Mach-O.
1582
Barry Warsawb110bad2006-07-21 14:51:07 +00001583- The email package has improved RFC 2231 support, specifically for
1584 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1585 (name*0=<blah>) parameter continuations. This may change the types of
1586 values returned from email.message.Message.get_param() and friends.
1587 Specifically in some cases where non-encoded continuations were used,
1588 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1589 will just return the string (since non-encoded continuations don't have
1590 charset and language parts).
1591
1592 Also, whereas % values were decoded in all parameter continuations, they are
1593 now only decoded in encoded parameter parts.
1594
Ronald Oussoren3075e162006-07-25 20:28:55 +00001595- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1596
1597- Bug #1517996: IDLE now longer shows the default Tk menu when a
1598 path browser, class browser or debugger is the frontmost window on MacOS X
1599
Barry Warsaw00decd72006-07-27 23:43:15 +00001600- Patch #1520294: Support for getset and member descriptors in types.py,
1601 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1602 of an object against these built-in types and more importantly, for getting
1603 their docstrings printed in the interactive interpreter's help() function.

Neal Norwitza1f10902006-07-12 07:28:29 +00001606Extension Modules
1607-----------------
1608
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001609- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1610 a socket operation on a socket with a timeout, the exception will be
1611 caught correctly. Previously, the exception was not caught.
1612
Thomas Heller1393d6a2006-07-28 21:43:20 +00001613- Patch #1529514: The _ctypes extension is now compiled on more
1614 openbsd target platforms.
1615
Tim Peters9cab5932006-07-28 00:30:00 +00001616- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1617 a memory leak, affecting pickles and deep copies.
1618
Tim Petersbc24eee2006-07-27 01:14:53 +00001619- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001620 Paul Eggert.
1621
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001622- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1623
Thomas Hellerce049a02006-07-14 17:51:14 +00001624- Patch #1521817: Index range checking on ctypes arrays containing
1625 exactly one element enabled again. This allows iterating over these
1626 arrays, without the need to check the array size before.
1627
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001628- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001629 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001630 /dev/null in certain cases; this is now fixed.
1631
Thomas Heller47d7a062006-07-12 08:43:47 +00001632- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1633 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001634
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001635- Because of a misspelled preprocessor symbol, ctypes was always
1636 compiled without thread support; this is now fixed.
1637
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001638- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1639 methods now allow their database parameter to be None as the
1640 sleepycat API allows.
1641
Matt Flemingec926502006-07-28 11:27:27 +00001642- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1643 bluetooth API compared with Linux and FreeBSD.
1644
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001645Tests
1646-----
1647
1648- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1649 how long the test file should take to play. Now accepts taking 2.93 secs
1650 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1651
Georg Brandl4793aa32006-07-28 18:31:39 +00001652- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1653 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1654 run via ``regrtest.py``. Now they do.

1663
1664- PythonLauncher now works correctly when the path to the script contains
1665 characters that are treated specially by the shell (such as quotes).
1666
1667- Bug #1527397: PythonLauncher now launches scripts with the working directory
1668 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001669 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001670 expect.

1680
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001681- Bug #1441486: The literal representation of -(sys.maxint - 1)
1682 again evaluates to a int object, not a long.
1683
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001684- Bug #1501934: The scope of global variables that are locally assigned
1685 using augmented assignment is now correctly determined.
1686
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001687- Bug #927248: Recursive method-wrapper objects can now safely
1688 be released.
1689
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001690- Bug #1417699: Reject locale-specific decimal point in float()
1691 and atof().
1692
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001693- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1694 omit a default "error" argument for NULL pointer. This allows
1695 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001696
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001697- Bug #1519018: 'as' is now validated properly in import statements.
1698
Neal Norwitz28746ab2006-07-09 22:14:42 +00001699- On 64 bit systems, int literals that use less than 64 bits are
1700 now ints rather than longs.
1701
Neal Norwitzed657552006-07-10 00:04:44 +00001702- Bug #1512814, Fix incorrect lineno's when code at module scope
1703 started after line 256.
1704
Tim Peters32a83612006-07-10 21:08:24 +00001705- New function ``sys._current_frames()`` returns a dict mapping thread
1706 id to topmost thread stack frame. This is for expert use, and is
1707 especially useful for debugging application deadlocks. The functionality
1708 was previously available in Fazal Majid's ``threadframe`` extension
1709 module, but it wasn't possible to do this in a wholly threadsafe way from
1710 an extension.

1717
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001718- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1719
Tim Peters32a83612006-07-10 21:08:24 +00001720- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001721 environment variable to be set in order to the SDK environment

1727
Thomas Woutersadd19112006-07-05 11:03:49 +00001728- string.Template() now correctly handles tuple-values. Previously,
1729 multi-value tuples would raise an exception and single-value tuples would
1730 be treated as the value they contain, instead.

Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001743
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001744- Bug #1514703: Only setup canvas window in turtle when the canvas
1745 is created.
1746
Martin v. Löwis7596e832006-07-01 15:33:37 +00001747- Bug #1513223: .close() of a _socketobj now releases the underlying
1748 socket again, which then gets closed as it becomes unreferenced.
1749
Fred Drake10497c82006-06-29 02:57:48 +00001750- Bug #1504333: Make sgmllib support angle brackets in quoted
1751 attribute values.
1752
1753- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1754 sgmllib ('[' and ']' were not accepted).

1757
Brett Cannon53ab5b72006-06-22 16:49:14 +00001758- Bug #1510580: The 'warnings' module improperly required that a Warning
1759 category be either a types.ClassType and a subclass of Warning. The proper
1760 check is just that it is a subclass with Warning as the documentation states.
1761
Georg Brandlad29e632006-06-21 17:45:17 +00001762- The compiler module now correctly compiles the new try-except-finally
1763 statement (bug #1509132).
1764
Neal Norwitz60373cd2006-06-22 06:30:50 +00001765- The wsgiref package is now installed properly on Unix.
1766

1768 shutdown when fileConfig() was called multiple times.
1769
Gerhard Häring762fbd32006-07-02 17:48:30 +00001770- The sqlite3 module did cut off data from the SQLite database at the first
1771 null character before sending it to a custom converter. This has been fixed
1772 now.
1773
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001774Extension Modules
1775-----------------
1776
Tim Peters112aad32006-07-19 00:03:19 +00001777- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1778 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1779 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001780
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001781- Assigning None to pointer type fields in ctypes structures possible
1782 overwrote the wrong fields, this is fixed now.
1783
1784- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1785 on non-Windows platforms.
1786
1787- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1788 integer or long, without range checking.
1789
1790- Patch #1517790: It is now possible to use custom objects in the ctypes
1791 foreign function argtypes sequence as long as they provide a from_param
1792 method, no longer is it required that the object is a ctypes type.
1793
1794- The '_ctypes' extension module now works when Python is configured
1795 with the --without-threads option.
1796
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001797- Bug #1513646: os.access on Windows now correctly determines write
1798 access, again.
1799
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001800- Bug #1512695: cPickle.loads could crash if it was interrupted with
1801 a KeyboardInterrupt.
1802

1810
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001811- Automate Windows build process for the Win64 SSL module.
1812
Tim Peters32a83612006-07-10 21:08:24 +00001813- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001814 Previously, the slight difference could cause compilation errors of the
1815 'zlib' module on systems with more than one version of zlib.
1816
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001817- The MSI compileall step was fixed to also support a TARGETDIR
1818 with spaces in it.

1848Core and builtins
1849-----------------
1850
Georg Brandla56b9152006-06-19 06:35:54 +00001851- Patch #1507676: Error messages returned by invalid abstract object operations
1852 (such as iterating over an integer) have been improved and now include the
1853 type of the offending object to help with debugging.
1854
Brett Cannonea3912b2006-06-13 21:46:41 +00001855- Bug #992017: A classic class that defined a __coerce__() method that returned
1856 its arguments swapped would infinitely recurse and segfault the interpreter.
1857
Neal Norwitz909eb122006-06-12 02:13:21 +00001858- Fix the socket tests so they can be run concurrently.
1859
Neal Norwitzb9845e72006-06-12 02:11:18 +00001860- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001861 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001862
Brett Cannon22565aa2006-06-09 22:31:23 +00001863- Bug #532646: object.__call__() will continue looking for the __call__
1864 attribute on objects until one without one is found. This leads to recursion
1865 when you take a class and set its __call__ attribute to an instance of the
1866 class. Originally fixed for classic classes, but this fix is for new-style.
1867 Removes the infinite_rec_3 crasher.
1868
Georg Brandl24250812006-06-09 18:45:48 +00001869- The string and unicode methods startswith() and endswith() now accept
1870 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1871
Brett Cannonde3b0522006-06-08 17:00:45 +00001872- Buffer objects, at the C level, never used the char buffer
1873 implementation even when the char buffer for the wrapped object was
1874 explicitly requested (originally returned the read or write buffer).
1875 Now a TypeError is raised if the char buffer is not present but is
1876 requested.
1877
Georg Brandlddbaa662006-06-04 21:56:52 +00001878- Patch #1346214: Statements like "if 0: suite" are now again optimized
1879 away like they were in Python 2.4.
1880
Georg Brandlb7c8f542006-05-27 12:30:25 +00001881- Builtin exceptions are now full-blown new-style classes instead of
1882 instances pretending to be classes, which speeds up exception handling
1883 by about 80% in comparison to 2.5a2.
1884
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001885- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1886 Unicode 4.1.
1887
Georg Brandlf4ef1162006-05-26 18:03:31 +00001888- Patch #921466: sys.path_importer_cache is now used to cache valid and
1889 invalid file paths for the built-in import machinery which leads to
1890 fewer open calls on startup.
1891
Tim Peters696cf432006-05-24 21:10:40 +00001892- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1893 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1894 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1895 the number of input digits (it was and remains linear-time for bases
1896 2, 4, 8, 16 and 32).
1897
Tim Petersb713ec22006-05-23 18:45:30 +00001898- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1899 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1900 an integer close to ``sys.maxint``. This was repaired by patch
1901 #1335972, which also gives a nice speedup.
1902
Richard Jonescebbefc2006-05-23 18:28:17 +00001903- Patch #1337051: reduced size of frame objects.
1904
1905- PyErr_NewException now accepts a tuple of base classes as its
1906 "base" parameter.
1907
Richard Jones7c88dcc2006-05-23 10:37:38 +00001908- Patch #876206: function call speedup by retaining allocated frame
1909 objects.
1910
Georg Brandl7b90e162006-05-18 07:01:27 +00001911- Bug #1462152: file() now checks more thoroughly for invalid mode
1912 strings and removes a possible "U" before passing the mode to the
1913 C library function.
1914
Neal Norwitz1004a532006-05-15 07:17:23 +00001915- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1916
Neal Norwitz373f0a72006-05-15 07:04:36 +00001917- Bug #1487966: Fix SystemError with conditional expression in assignment
1918
Martin v. Löwis879768d2006-05-11 13:28:43 +00001919- WindowsError now has two error code attributes: errno, which carries
1920 the error values from errno.h, and winerror, which carries the error
1921 values from winerror.h. Previous versions put the winerror.h values
1922 (from GetLastError()) into the errno attribute.
1923
Martin v. Löwis77736712006-05-04 05:51:03 +00001924- Patch #1475845: Raise IndentationError for unexpected indent.
1925
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001926- Patch #1479181: split open() and file() from being aliases for each other.
1927
Tim Peters44bd9862006-06-01 13:49:23 +00001928- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1929 methods were always silently ignored by dictionaries when comparing keys.
1930 They are now passed through (except when using the C API function
1931 ``PyDict_GetItem()``, whose semantics did not change).
1932
1933- Bug #1456209: In some obscure cases it was possible for a class with a
1934 custom ``__eq__()`` method to confuse dict internals when class instances
1935 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1936 No, you don't have any code that did this ;-)

1949
Nick Coghlanc649ec52006-05-29 12:43:05 +00001950- Patch #1478788 (modified version): The functional extension module has
1951 been renamed to _functools and a functools Python wrapper module added.
1952 This provides a home for additional function related utilities that are
1953 not specifically about functional programming. See PEP 309.
1954
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001955- Patch #1493701: performance enhancements for struct module.

1963 enabled builds on Windows and systems with Posix threads support.
1964
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001965- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1966 (up to the system limit of 32K characters).
1967
1968- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1969 As a result, these functions now raise WindowsError instead of OSError.
1970
Tim Peters7a822da2006-05-25 21:50:17 +00001971- ``time.clock()`` on Win64 should use the high-performance Windows
1972 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1973 Windows platforms).
1974
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001975- Calling Tk_Init twice is refused if the first call failed as that
1976 may deadlock.
1977
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001978- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1979 accept it without potentially using an uninitialized pointer.
1980
1981- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
1982 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF

1992 results. It could previously incorrectly return 0 in some cases.
1993 Fixes SF bug 1493322 (pybsddb bug 1184012).
1994
Gregory P. Smithff7d9912006-06-08 05:17:08 +00001995- bsddb: the bsddb.dbtables Modify method now raises the proper error and

1997 Fixes SF python patch/bug #1408584.
1998
Gregory P. Smith506f7b52006-06-15 08:52:32 +00001999- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00002000 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00002001 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
2002 database calls that would previously deadlock. [SF python bug #775414]

Martin v. Löwis5ecad9c2006-06-17 09:20:41 +00002020- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
2021
Martin v. Löwis337487e2006-06-17 09:15:14 +00002022- Patch #763580: Add name and value arguments to Tkinter variable
2023 classes.
2024
Georg Brandl83cc0d02006-06-14 08:50:03 +00002025- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
2026 mime.types file for determining MIME types.
2027
Georg Brandl2605ca82006-06-14 06:08:31 +00002028- Bug #1339007: Shelf objects now don't raise an exception in their
2029 __del__ method when initialization failed.
2030
Martin v. Löwisd8251432006-06-14 05:21:04 +00002031- Patch #1455898: The MBCS codec now supports the incremental mode for
2032 double-byte encodings.
2033
Tim Peters43898b42006-06-14 04:09:25 +00002034- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
2035 guarantee that adjacent triples in the return list always describe
2036 non-adjacent blocks. Previously, a pair of matching blocks could end
2037 up being described by multiple adjacent triples that formed a partition
2038 of the matching pair.
2039
Greg Ward0e0c9f42006-06-11 16:24:11 +00002040- Bug #1498146: fix optparse to handle Unicode strings in option help,
2041 description, and epilog.
2042
Greg Wardd1c797e2006-06-11 14:42:41 +00002043- Bug #1366250: minor optparse documentation error.
2044
Greg Ward7f547402006-06-11 00:40:49 +00002045- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
2046 clarify docs.
2047
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00002048- The wsgiref package has been added to the standard library.
2049
Nick Coghlan676725d2006-06-08 13:54:49 +00002050- The functions update_wrapper() and wraps() have been added to the functools
2051 module. These make it easier to copy relevant metadata from the original
2052 function when writing wrapper functions.
2053
Tim Petersd6a9eef2006-06-05 01:48:21 +00002054- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
2055 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00002056
Martin v. Löwis3f767792006-06-04 19:36:28 +00002057- Patch #1359618: Speed up charmap encoder by using a trie structure
2058 for lookup.
2059
Tim Petersd609b1a2006-06-02 23:22:51 +00002060- The functions in the ``pprint`` module now sort dictionaries by key
2061 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
2062 if and only if its display required more than one line, although that
2063 wasn't documented. The new behavior increases predictability; e.g.,
2064 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
2065
Georg Brandlfd9a4b12006-05-29 20:57:01 +00002066- Patch #1497027: try HTTP digest auth before basic auth in urllib2
2067 (thanks for J. J. Lee).
2068
Georg Brandl2b330372006-05-28 20:23:12 +00002069- Patch #1496206: improve urllib2 handling of passwords with respect to
2070 default HTTP and HTTPS ports.
2071
George Yoshidaf3c65de2006-05-28 16:39:09 +00002072- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
2073
Bob Ippolito7298f272006-05-23 18:43:47 +00002074- Patch #1281707: speed up gzip.readline.
2075
Georg Brandlb89316f2006-05-17 15:51:16 +00002076- Patch #1180296: Two new functions were added to the locale module:
2077 format_string() to get the effect of "format % items" but locale-aware,
2078 and currency() to format a monetary number with currency sign.
2079
Georg Brandle3a25832006-05-17 14:56:04 +00002080- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
2081 and several features added, such as speed and geometry control.
2082
Georg Brandl49c8f4c2006-05-15 19:30:35 +00002083- Patch #1488881: add support for external file objects in bz2 compressed
2084 tarfiles.
2085
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002086- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
2087 stdout arguments, making it possible to redirect input and output
2088 for remote debugging.
2089
2090- Patch #1484695: Update the tarfile module to version 0.8. This fixes
2091 a couple of issues, notably handling of long file names using the
2092 GNU LONGNAME extension.
2093
2094- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
2095 new flag when ``name`` is already the name of an option flag.
2096
2097- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
2098 package.
2099
2100- Patch #1472854: make the rlcompleter.Completer class usable on non-
2101 UNIX platforms.
2102
2103- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
2104
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00002105- Bug #1472827: correctly escape newlines and tabs in attribute values in
2106 the saxutils.XMLGenerator class.

2138
2139*Release date: 27-APR-2006*
2140
2141Core and builtins
2142-----------------
2143
Thomas Heller1b046642006-04-18 18:51:06 +00002144- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2145 by converting these apis from macros into exported functions again:
2146
2147 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2148 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2149 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
2150 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
2151 PyRun_String Py_CompileString
2152
Martin v. Löwis45294a92006-04-18 06:24:08 +00002153- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2154
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002155- All uses of PyStructSequence_InitType have been changed to initialize
2156 the type objects only once, even if the interpreter is initialized
2157 multiple times.
2158
Neal Norwitz61546162006-04-14 05:20:28 +00002159- Bug #1454485, array.array('u') could crash the interpreter. This was
2160 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2161 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2162
2163- Py_UNICODE is unsigned. It was always documented as unsigned, but
2164 due to a bug had a signed value in previous versions.
2165
Tim Peters3a5e8b12006-04-11 01:44:07 +00002166- Patch #837242: ``id()`` of any Python object always gives a positive
2167 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2168 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002169 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002170 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002171
Tim Peters3a5e8b12006-04-11 01:44:07 +00002172 def __hash__(self):
2173 return id(self) # WRONG
2174
2175 because a hash result must be a (short) Python int but it was always
2176 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002177 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002178 was always usable as a hash value before this patch. That's no longer
2179 necessarily so.
2180
2181- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002182 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002183 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002184 #1454844)
2185
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002186- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2187 involving generators that have paused outside of any ``try`` or ``with``
2188 blocks. (In 2.5a1, a paused generator that was part of a reference
2189 cycle could not be garbage collected, regardless of whether it was
2190 paused in a ``try`` or ``with`` block.)

2204 the cachesize parameter.
2205
2206- Bug #1149413: bsddb.*open() no longer raises an exception when using
2207 a temporary db (file=None) with the 'n' flag to truncate on open.
2208
2209- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
2210 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00002211
Armin Rigoa9017c32006-04-19 11:50:27 +00002212- Patch #1062014: AF_UNIX sockets under Linux have a special

2220 abusing errno.
2221
Tim Peters711bf302006-04-25 03:31:36 +00002222- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2223 a doctest to be skipped (the code is not run, and the expected output
2224 or exception is ignored).
2225
Nick Coghlanda2268f2006-04-24 04:37:15 +00002226- Fixed contextlib.nested to cope with exceptions being raised and
2227 caught inside exit handlers.
2228
Greg Wardab05edc2006-04-23 03:47:58 +00002229- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2230 hex, octal, or binary; add ``append_const`` action; keep going if
2231 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2232 added ``epilog`` for better help generation).
2233
Tim Peters21fbd572006-04-21 21:18:10 +00002234- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2235 called from a thread spawned as a side effect of importing a module.
2236
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002237- The pydoc module now supports documenting packages contained in
2238 .zip or .egg files.
2239
2240- The pkgutil module now has several new utility functions, such
2241 as ``walk_packages()`` to support working with packages that are either
2242 in the filesystem or zip files.
2243
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002244- The mailbox module can now modify and delete messages from
2245 mailboxes, in addition to simply reading them. Thanks to Gregory
2246 K. Johnson for writing the code, and to the 2005 Google Summer of
2247 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002248
Tim Petersc7605f22006-04-17 21:12:33 +00002249- The ``__del__`` method of class ``local`` in module ``_threading_local``
2250 returned before accomplishing any of its intended cleanup.
2251
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002252- Patch #790710: Add breakpoint command lists in pdb.

Anthony Baxtere29002c2006-04-12 12:07:31 +00002258- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
2259 Windows. Bug #1469163.
2260
Phillip J. Eby47032112006-04-11 01:07:43 +00002261- The warnings, linecache, inspect, traceback, site, and doctest modules
2262 were updated to work correctly with modules imported from zipfiles or
2263 via other PEP 302 __loader__ objects.
2264
Martin v. Löwis17de8ff2006-04-10 15:55:37 +00002265- Patch #1467770: Reduce usage of subprocess._active to processes which

Martin v. Löwis4be4e652006-04-17 19:25:49 +00002278- The Makefile now has a reindent target, which runs reindent.py on
2279 the library.
2280

2286 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002287 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002288 CXX from --with-cxx-main, see description in README.
2289

2293
Tim Peters8931ff12006-05-13 23:28:20 +00002294- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2295 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,

2297
Anthony Baxter51bcb682006-04-05 14:51:42 +00002298Tests

2300
Nick Coghlanda2268f2006-04-24 04:37:15 +00002301- test_contextlib now checks contextlib.nested can cope with exceptions
2302 being raised and caught inside exit handlers.
2303
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002304- test_cmd_line now checks operation of the -m and -c command switches
2305
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002306- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2307 it separately and by hand. It also wasn't cleaning up its changes to
2308 the current Decimal context.
2309
Thomas Woutersabd08882006-04-26 15:53:30 +00002310- regrtest.py now has a -M option to run tests that test the new limits of
2311 containers, on 64-bit architectures. Running these tests is only sensible
2312 on 64-bit machines with more than two gigabytes of memory. The argument
2313 passed is the maximum amount of memory for the tests to use.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002334What's New in Python 2.5 alpha 1?
2335=================================
2336
Anthony Baxterebed3f62006-04-03 15:03:44 +00002337*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002338
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002339Core and builtins
2340-----------------
2341
Nick Coghlan43832302006-04-23 17:04:07 +00002342- PEP 338: -m command line switch now delegates to runpy.run_module
2343 allowing it to support modules in packages and zipfiles
2344
Martin v. Löwisc661b882006-04-20 04:54:23 +00002345- On Windows, .DLL is not an accepted file name extension for
2346 extension modules anymore; extensions are only found if they
2347 end in .PYD.
2348
Martin v. Löwisea62d252006-04-03 10:56:49 +00002349- Bug #1421664: sys.stderr.encoding is now set to the same value as
2350 sys.stdout.encoding.
2351
Neal Norwitz92e212f2006-04-03 04:48:37 +00002352- __import__ accepts keyword arguments.
2353
Georg Brandlccadf842006-03-31 18:54:53 +00002354- Patch #1460496: round() now accepts keyword arguments.
2355
Anthony Baxter262c00a2006-03-30 10:53:17 +00002356- Fixed bug #1459029 - unicode reprs were double-escaped.
2357
Hye-Shik Changd478f342006-03-23 12:32:36 +00002358- Patch #1396919: The system scope threads are reenabled on FreeBSD
2359 5.4 and later versions.
2360
Neal Norwitze98ccf62006-03-23 05:39:47 +00002361- Bug #1115379: Compiling a Unicode string with an encoding declaration
2362 now gives a SyntaxError.
2363
Georg Brandlabd1ff82006-03-18 07:59:59 +00002364- Previously, Python code had no easy way to access the contents of a
2365 cell object. Now, a ``cell_contents`` attribute has been added
2366 (closes patch #1170323).
2367
Tim Peterscf79aac2006-03-16 01:14:46 +00002368- Patch #1123430: Python's small-object allocator now returns an arena to
2369 the system ``free()`` when all memory within an arena becomes unused
2370 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2371 freed. Some applications will see a drop in virtual memory size now,
2372 especially long-running applications that, from time to time, temporarily
2373 use a large number of small objects. Note that when Python returns an
2374 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002375 platform C library will in turn return that memory to the operating system.
2376 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002377 appears to be effective at least on Microsoft C and gcc-based systems.
2378 Thanks to Evan Jones for hard work and patience.
2379
Georg Brandl533ff6f2006-03-08 18:09:27 +00002380- Patch #1434038: property() now uses the getter's docstring if there is
2381 no "doc" argument given. This makes it possible to legitimately use
2382 property() as a decorator to produce a read-only property.
2383
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002384- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2385 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2386 of requiring an int or long in slicing and a few other contexts, enabling
2387 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2388
Neal Norwitz995acdf2006-03-07 05:01:00 +00002389- Fixed various bugs reported by Coverity's Prevent tool.
2390
Brett Cannonbf364092006-03-01 04:25:17 +00002391- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2392 new exception base class, BaseException, which has a new message attribute.
2393 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2394 Raising a string exception now raises a DeprecationWarning.
2395
Thomas Woutersfb609f42006-02-28 16:37:25 +00002396- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2397 explicitly relative, using 'from .module import name' to mean 'from the same
2398 package as this module is in. Imports without dots still default to the
2399 old relative-then-absolute, unless 'from __future__ import
2400 absolute_import' is used.
2401
Brett Cannona7446e32006-02-27 23:39:10 +00002402- Properly check if 'warnings' raises an exception (usually when a filter set
2403 to "error" is triggered) when raising a warning for raising string
2404 exceptions.
2405
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002406- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002407 The name was removed from Include/code.h.
2408
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002409- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002410
Guido van Rossum1968ad32006-02-25 22:38:04 +00002411- Patch 1433928:
2412 - The copy module now "copies" function objects (as atomic objects).
2413 - dict.__getitem__ now looks for a __missing__ hook before raising
2414 KeyError.
2415
Tim Peters84ef21c2006-02-28 20:39:06 +00002416- PEP 343: with statement implemented. Needs ``from __future__ import
2417 with_statement``. Use of 'with' as a variable will generate a warning.
2418 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002419 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002420 The following objects have __context__ methods:
2421 - The built-in file type.
2422 - The thread.LockType type.
2423 - The following types defined by the threading module:
2424 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2425 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002426
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002427- Fix the encodings package codec search function to only search
2428 inside its own package. Fixes problem reported in patch #1433198.
2429
2430 Note: Codec packages should implement and register their own
2431 codec search function. PEP 100 has the details.
2432
Tim Peters9ea89d22006-06-04 03:26:02 +00002433- PEP 353: Using ``Py_ssize_t`` as the index type.
2434
2435- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2436 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2437 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2438 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2439 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002440
Neal Norwitzfc76d632006-01-10 06:03:13 +00002441- Patch #1400181, fix unicode string formatting to not use the locale.
2442 This is how string objects work. u'%f' could use , instead of .
2443 for the decimal point. Now both strings and unicode always use periods.
2444
Neal Norwitz671b9e32006-01-09 07:07:12 +00002445- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2446 configure would break checking curses.h.
2447
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002448- Bug #959576: The pwd module is now builtin. This allows Python to be
2449 built on UNIX platforms without $HOME set.
2450
Neal Norwitzc10978f2005-12-19 06:07:16 +00002451- Bug #1072182, fix some potential problems if characters are signed.
2452
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002453- Bug #889500, fix line number on SyntaxWarning for global declarations.
2454
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002455- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2456
Neal Norwitze7214a12005-12-18 05:03:17 +00002457- Support for converting hex strings to floats no longer works.
2458 This was not portable. float('0x3') now raises a ValueError.
2459
Barry Warsaw2a38a862005-12-18 01:27:35 +00002460- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002461 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002462 is now displayed in interactive prompt banner.
2463
Georg Brandlfa166682005-12-17 21:45:17 +00002464- Implementation of PEP 341 - Unification of try/except and try/finally.
2465 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002466 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002467
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002468- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2469 now encodes backslash correctly.
2470
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002471- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2472
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002473- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002474 and long longs.
2475
Neal Norwitz67715f02005-11-09 06:59:35 +00002476- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002477 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002478 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002479
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002480- Replaced most Unicode charmap codecs with new ones using the
2481 new Unicode translate string feature in the builtin charmap
2482 codec; the codecs were created from the mapping tables available
2483 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2484 encodings now include a mapping for the Apple logo)
2485
Tim Peterse3547fd2005-12-16 23:13:57 +00002486- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002487
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002488- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002489
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002490- A new AST parser implementation was completed. The abstract
2491 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002492 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002493
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002494- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002495 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2496
Neal Norwitz708e51a2005-10-03 04:48:15 +00002497- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2498
Neal Norwitz11bd1192005-10-03 00:54:56 +00002499- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2500 Provide a warning when a directory is passed on the command line.
2501
Neal Norwitz40d37812005-10-02 01:48:49 +00002502- Fix segfault with invalid coding.
2503
2504- SF bug #772896: unknown encoding results in MemoryError.
2505
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002506- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002507 supported a __len__() method which evaluated to False when the iterator
2508 was empty.
2509
Guido van Rossum630db602005-09-20 18:49:54 +00002510- On 64-bit platforms, when __len__() returns a value that cannot be
2511 represented as a C int, raise OverflowError.
2512
Skip Montanarof8948ca2005-09-19 03:54:46 +00002513- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002514 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002515
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002516- SF bug #893549: parsing keyword arguments was broken with a few format
2517 codes.
2518
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002519- Changes donated by Elemental Security to make it work on AIX 5.3
2520 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2521 bug #105470: test_pwd fails on 64bit system (Opteron).
2522
Guido van Rossum539c6622005-09-14 17:49:54 +00002523- Changes donated by Elemental Security to make it work on HP-UX 11 on
2524 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2525
Georg Brandl4550b8d2005-08-26 06:43:52 +00002526- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002527 (fixes bug #1119418).
2528
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002529- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2530
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002531- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2532 exceptions that cause a function to exit.
2533
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002534- The implementation of set() and frozenset() was revised to use its
2535 own internal data structure. Memory consumption is reduced by 1/3
2536 and there are modest speed-ups as well. The API is unchanged.
2537
Tim Petersde7990b2005-07-17 23:45:23 +00002538- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2539
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002540- SF bug #1229429: PyObject_CallMethod failed to decrement some
2541 reference counts in some error exit cases.
2542
Tim Petersecc6e6a2005-07-10 22:30:55 +00002543- SF bug #1185883: Python's small-object memory allocator took over
2544 a block managed by the platform C library whenever a realloc specified
2545 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002546 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002547 portable way to copy data from the C-managed block into Python's
2548 small-object space without risking a memory fault. Python's small-object
2549 realloc now leaves such blocks under the control of the platform C
2550 realloc.
2551
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002552- SF bug #1232517: An overflow error was not detected properly when
2553 attempting to convert a large float to an int in os.utime().
2554
Raymond Hettinger3296e692005-06-29 23:29:56 +00002555- SF bug #1224347: hex longs now print with lowercase letters just
2556 like their int counterparts.
2557
Michael W. Hudson188d4362005-06-20 16:52:57 +00002558- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2559 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2560 interpreter states; back out that fix and do a better job (see
2561 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2562 for a longer write-up of the problem).
2563
Michael W. Hudsondf888462005-06-03 14:41:55 +00002564- SF patch #1180995: marshal now uses a binary format by default when
2565 serializing floats.
2566
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002567- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2568 the routines that promise to produce IEEE 754 binary representations
2569 of floats now simply copy bytes around.
2570
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002571- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2572 278.
2573
Brett Cannonc3647ac2005-04-26 03:45:26 +00002574- patch #1109424: int, long, float, complex, and unicode now check for the
2575 proper magic slot for type conversions when subclassed. Previously the
2576 magic slot was ignored during conversion. Semantics now match the way
2577 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002578 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002579 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002580 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002581
Barry Warsawc8d907c2005-04-19 23:43:40 +00002582- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2583 NULL, now raise an AttributeError when attempting to set or delete the
2584 attribute. Previously a TypeError was raised, but this was inconsistent
2585 with the equivalent pure-Python implementation.
2586
Michael W. Hudson774479c2005-04-18 08:46:17 +00002587- It is now safe to call PyGILState_Release() before
2588 PyEval_InitThreads() (note that if there is reason to believe there
2589 are multiple threads around you still must call PyEval_InitThreads()
2590 before using the Python API; this fix is for extension modules that
2591 have no way of knowing if Python is multi-threaded yet).
2592
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002593- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2594 disabled caused a crash.
2595
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002596- Bug #1165306: instancemethod_new allowed the creation of a method

2645 current thread state when the auto-GIL-state machinery knows about
2646 it (since the thread state is being deleted, continuing to remember it
2647 can't help, but can hurt if another thread happens to get created with
2648 the same thread id).

Anthony Baxterc51ee692006-04-01 00:57:31 +00002858- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002859 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or

Tim Petersc17976e2006-04-01 00:26:53 +00002863- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2864 aren't officially supported here, and trying to use them will probably
2865 raise an exception some day. But dicts have been allowed, and "mostly
2866 worked", so support for them won't go away without warning.
2867
Georg Brandl338ef7d2006-03-31 18:42:16 +00002868- Bug #1445068: getpass.getpass() can now be given an explicit stream
2869 argument to specify where to write the prompt.
2870

2877 key to be used for signing the uploaded code.
2878
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002879- Queue.Queue objects now support .task_done() and .join() methods
2880 to make it easier to monitor when daemon threads have completed
2881 processing all enqueued tasks. Patch #1455676.
2882
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002883- popen2.Popen objects now preserve the command in a .cmd attribute.
2884

2886
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002887- email 4.0 package now integrated. This is largely the same as the email 3.0
2888 package that was included in Python 2.3, except that PEP 8 module names are
2889 now used (e.g. mail.message instead of email.Message). The MIME classes
2890 have been moved to a subpackage (e.g. email.mime.text instead of
2891 email.MIMEText). The old names are still supported for now. Several
2892 deprecated Message methods have been removed and lots of bugs have been
2893 fixed. More details can be found in the email package documentation.
2894
Walter Dörwald40108c92006-03-27 08:15:44 +00002895- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2896 (a subclass of tuple) that provides incremental decoders and encoders
2897 (a way to use stateful codecs without the stream API). Python functions
2898 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2899 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2900 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002901
Walter Dörwald067db482006-03-15 22:17:27 +00002902- Patch #1359365: Calling next() on a closed StringIO.String object raises
2903 a ValueError instead of a StopIteration now (like file and cString.String do).
2904 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2905 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002906
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002907- A regrtest option -w was added to re-run failed tests in verbose mode.

2913 grew an optional 'generation' argument.
2914
Martin v. Löwisfbab90e2006-03-05 13:36:04 +00002915- A library msilib to generate Windows Installer files, and a distutils

2975 LoadError as documented, instead of IOError. For compatibility,
2976 LoadError subclasses IOError.
2977

Tim Peterse3547fd2005-12-16 23:13:57 +00002979 SHA1, 224, 256, 384, and 512. Note that recent developments make the
2980 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
2981 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
2982 Ronald L. Rivest offered this advice for Python:
2983
2984 "The consensus of researchers in this area (at least as
2985 expressed at the NIST Hash Function Workshop 10/31/05),
2986 is that SHA-256 is a good choice for the time being, but
2987 that research should continue, and other alternatives may
2988 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00002989
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00002990- Added a subset of Fredrik Lundh's ElementTree package. Available

3148
Guido van Rossumd0641422005-02-03 15:01:24 +00003149- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
3150 disables recursive traversal through instance attributes, which can
3151 be exploited in various ways.
3152
Tim Peterse3547fd2005-12-16 23:13:57 +00003153- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00003154 flags on the HTTP listening socket.
3155
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00003156- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
3157 Fixed by reading the HTTP body in chunks instead of one big socket.read().
3158
Fred Drakefbdeaad2006-07-29 16:56:15 +00003159- Patches #893642, #1039083: add allow_none, encoding arguments to

3165
Martin v. Löwis22b457e2005-01-16 08:40:58 +00003166- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
3167
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003168- Enhancements to the csv module:
3169
3170 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003171 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003172 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003173 + Dialect parameter parsing has been re-implemented to improve error
3174 reporting.
3175 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3176 dictates.
3177 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003178 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003179 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003180 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3181 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003182 + reader now allows \r characters to be quoted (previously it only allowed
3183 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003184 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003185 + Dialect classes passed to the module are no longer instantiated by
3186 the module before being parsed (the former validation scheme required
3187 this, but the mechanism was unreliable).
3188 + The dialect registry now contains instances of the internal
3189 C-coded dialect type, rather than references to python objects.
3190 + the internal c-coded dialect type is now immutable.
3191 + register_dialect now accepts the same keyword dialect specifications
3192 as the reader and writer, allowing the user to register dialects
3193 without first creating a dialect class.
3194 + a configurable limit to the size of parsed fields has been added -
3195 previously, an unmatched quote character could result in the entire
3196 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003197 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003198 the parser field size limit (returning the former limit). The initial
3199 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003200 + A line_num attribute has been added to the reader object, which tracks
3201 the number of lines read from the source iterator. This is not
3202 the same as the number of records returned, as records can span
3203 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003204 + reader and writer objects were not being registered with the cyclic-GC.
3205 This has been fixed.
3206
Brett Cannone6539c42005-01-08 02:43:53 +00003207- _DummyThread objects in the threading module now delete self.__block that is
3208 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3209 lock primitives tend to be limited in number and thus should not be wasted on
3210 a _DummyThread object. Fixes bug #1089632.
3211
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003212- The imghdr module now detects Exif files.
3213
Raymond Hettinger6065d322004-12-20 23:51:53 +00003214- StringIO.truncate() now correctly adjusts the size attribute.
3215 (Bug #951915).
3216
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003217- locale.py now uses an updated locale alias table (built using
3218 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3219 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003220 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003221
Raymond Hettinger3557f422004-12-07 12:02:02 +00003222- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3223
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003224- the pickle module no longer accepts the deprecated None option in the
3225 args tuple returned by __reduce__().
3226
Brett Cannon84667c02004-12-07 03:25:18 +00003227- optparse now optionally imports gettext. This allows its use in setup.py.
3228
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003229- the pickle module no longer uses the deprecated bin parameter.
3230
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003231- the shelve module no longer uses the deprecated binary parameter.
3232
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003233- the pstats module no longer uses the deprecated ignore() method.
3234
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003235- the filecmp module no longer uses the deprecated use_statcache argument.
3236
Raymond Hettinger664347b2004-12-04 21:21:53 +00003237- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3238 extended or overridden by subclasses. Formerly, the subclassed method would
3239 be ignored by the rest of the module. (Bug #1078905).
3240
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003241- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003242 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003243
Walter Dörwald36733692004-12-22 12:50:50 +00003244- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3245 once when a size argument is given. This prevents a buffer overflow in the
3246 tokenizer with very long source lines.
3247
Barry Warsaw538561e2006-01-01 21:48:54 +00003248- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3249 immediately after creating the object, without any intervening
3250 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003251
Skip Montanaro05885812005-01-16 20:48:27 +00003252- The reconvert.quote function can now emit triple-quoted strings. The
3253 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003254
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003255- ``UserString.MutableString`` now supports negative indices in
3256 ``__setitem__`` and ``__delitem__``
3257
Greg Ward40407942005-03-05 02:53:17 +00003258- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3259 correctly.
3260
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003261- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3262 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3263 character even if the user has passed a size parameter to get a proper
3264 line ending. Remove the special handling of a "\r\n" that has been split
3265 between two lines.
3266
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003267- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3268 about illegal code points. The codec now supports PEP 293 style error
3269 handlers.
3270
Walter Dörwald78a78b02005-09-01 12:04:29 +00003271- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003272 from the input stream, so that the output is a byte string in the correct
3273 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003274
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003275- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3276 considering it exactly like a '*'.
3277
Walter Dörwald007f8df2005-10-09 19:42:27 +00003278- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3279 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003280
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003281- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3282
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003283- Patch #1413711: Certain patterns of differences were making difflib
3284 touch the recursion limit.
3285
Walter Dörwald58917a62006-03-31 15:26:22 +00003286- Bug #947906: An object oriented interface has been added to the calendar
3287 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003288 called as a script (e.g. via ``python -mcalendar``). Localized month and
3289 weekday names can be ouput (even if an exotic encoding is used) using
3290 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003291
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003292Build
3293-----
3294
Neal Norwitz602d3392006-03-31 08:21:40 +00003295- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3296 by using -mieee gcc option.
3297
Martin v. Löwis86d66262006-02-17 08:40:11 +00003298- Patch #1432345: Make python compile on DragonFly.
3299
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003300- Build support for Win64-AMD64 was added.
3301
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003302- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3303
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003304- Patch #881820: look for openpty and forkpty also in libbsd.
3305
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003306- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3307 The zlib module is now builtin on Windows.
3308
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003309- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3310
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003311- Bug #1189330: configure did not correctly determine the necessary
3312 value of LINKCC if python was built with GCC 4.0.
3313
Trent Mick8321b422005-07-26 02:29:21 +00003314- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3315 vulnerability in zlib 1.2.1 and 1.2.2.
3316
Brett Cannon08cd5982005-04-24 22:26:38 +00003317- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3318 flags that change binary compatibility. Changes were also made to
3319 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003320 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003321
Bob Ippolitoed233462005-03-29 13:47:59 +00003322- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3323 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3324 no longer exists). This configure patch makes things right.
3325
Martin v. Löwise2713be2005-03-08 15:03:08 +00003326- Bug #1158607: Build with --disable-unicode again.
3327
Brett Cannon46d96232005-02-16 00:07:19 +00003328- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3329 defined. Discovered as a result of not being able to build on OS X.
3330
Brett Cannon516592f2004-12-07 00:42:59 +00003331- setup.py now uses the directories specified in LDFLAGS using the -L option
3332 and in CPPFLAGS using the -I option for adding library and include
3333 directories, respectively, for compiling extension modules against. This has
3334 led to the core being compiled using the values in CPPFLAGS. It also removes
3335 the need for the special-casing of both DarwinPorts and Fink for darwin since
3336 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3337 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3338 Fink, ``-I/opt/local/include`` for DarwinPorts).
3339
Brett Cannon43802422005-02-10 20:48:03 +00003340- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3341 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3342 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3343 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003345C API
3346-----
3347
Tim Petersc9d78aa2006-03-26 23:27:58 +00003348- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3349 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3350 is obtained via the ``PyObject_`` family, it must be released via the
3351 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3352 always been officially true, but when Python's small-object allocator was
3353 introduced, an attempt was made to cater to a few extension modules
3354 discovered at the time that obtained memory via ``PyObject_New`` but
3355 released it via ``PyMem_DEL``. It's years later, and if such code still
3356 exists it will fail now (probably with segfaults, but calling wrong
3357 low-level memory management functions can yield many symptoms).
3358
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003359- Added a C API for set and frozenset objects.
3360
Raymond Hettinger66517482004-12-03 11:45:13 +00003361- Removed PyRange_New().
3362
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003363- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3364 mapping argument now. This string is used as a mapping table. Byte values
3365 greater than the length of the string and 0xFFFE are treated as undefined
3366 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003373
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00003374- Patch #1276356: New resource "urlfetch" is implemented. This enables
