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

120 holds the last (strong) reference to its referent.
121
Guido van Rossumaa975432008-04-10 22:43:58 +0000122- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
123 having a self-referential tuple, which is possible from C code. Nor did
124 object's tp_str consider that a type's tp_str could do something that could
125 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
126 respectively, fixed the issues. (Backport of r58288 from trunk.)

132 reference on the outer class name.
133
Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +0000134- Issue #1477: With narrow Unicode builds, the unicode escape sequence
135 \Uxxxxxxxx did not accept values outside the Basic Multilingual Plane. This
136 affected raw unicode literals and the 'raw-unicode-escape' codec. Now
137 UTF-16 surrogates are generated in this case, like normal unicode literals
138 and the 'unicode-escape' codec.
139
Neal Norwitzb3635f92008-03-18 04:17:36 +0000140- Issue #2321: use pymalloc for unicode object string data to reduce
141 memory usage in some circumstances.

147 parameter but was not verifying that it was greater than zero. Values
148 less than zero will now raise a SystemError and return NULL to indicate a
149 bug in the calling C code.
150
Gregory P. Smith9aa040d2008-06-02 00:07:25 +0000151- Issue #2588, #2589: Fix potential integer underflow and overflow
152 conditions in the PyOS_vsnprintf C API function.
153
Gregory P. Smithcae7f882008-09-07 06:44:12 +0000154- Issue #1204: The configure script now tests for additional libraries
155 that may be required when linking against readline. This fixes issues
156 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
Georg Brandld9f1da02008-03-29 01:50:46 +0000157

1185-----------------
1186
Neal Norwitz0bcafac2006-09-11 08:51:17 +00001187- Make _PyGILState_NoteThreadState() static, it was not used anywhere
1188 outside of pystate.c and should not be necessary.
1189
Brett Cannon19d76c52006-09-09 07:18:44 +00001190- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
1191 allows calling unicode() on exceptions classes directly to succeed.
1192
Georg Brandlecab6232006-09-06 06:47:02 +00001193- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
1194 Also make sure that every exception class has __module__ set to
1195 'exceptions'.
1196
Georg Brandl37a9e572006-09-06 06:09:34 +00001197- Bug #1550983: emit better error messages for erroneous relative
1198 imports (if not in package and if beyond toplevel package).
1199
Tim Peterscbdd3502006-09-05 01:47:53 +00001200- Overflow checking code in integer division ran afoul of new gcc

Neal Norwitz29a5fdb2006-09-05 02:21:38 +00001208- The return tuple from str.rpartition(sep) is (tail, sep, head) where
1209 head is the original string if sep was not found.
1210
Neal Norwitz3b3aae02006-09-05 03:56:01 +00001211- Bug #1520864: unpacking singleton tuples in list comprehensions and
1212 generator expressions (x for x, in ... ) works again. Fixing this problem
1213 required changing the .pyc magic number. This means that .pyc files
1214 generated before 2.5c2 will be regenerated.

1327-----------------
1328
Neal Norwitz24b6f202006-09-05 04:43:56 +00001329- Fix infinite recursion when subclassing long and overriding __hash__.
1330
1331- Fix concatenation (+=) of long strings.
1332
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001333- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001334 compared equal or unequal to a string and a UnicodeDecodeError
1335 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001336
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001337 Instead, the equal (==) and unequal (!=) comparison operators will
1338 now issue a UnicodeWarning and interpret the two objects as
1339 unequal. The UnicodeWarning can be filtered as desired using
1340 the warning framework, e.g. silenced completely, turned into an
1341 exception, logged, etc.
1342
1343 Note that compare operators other than equal and unequal will still
1344 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001345
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001346- Fix segfault when doing string formatting on subclasses of long.
1347
1348- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1349 with new-style classes.
1350
1351- Fix bug related to __len__ functions returning negative values with
1352 classic classes.
1353
1354- Patch #1538606, Fix __index__() clipping. There were some problems
1355 discovered with the API and how integers that didn't fit into Py_ssize_t
1356 were handled. This patch attempts to provide enough alternatives
1357 to effectively use __index__.
1358
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001359- Bug #1536021: __hash__ may now return long int; the final hash
1360 value is obtained by invoking hash on the long int.
1361
Thomas Hellerab1049c2006-08-08 17:37:00 +00001362- Bug #1536786: buffer comparison could emit a RuntimeWarning.
1363
Georg Brandl7e3ba2a2006-08-06 08:23:54 +00001364- Bug #1535165: fixed a segfault in input() and raw_input() when
1365 sys.stdin is closed.
1366
Thomas Heller74d36f02006-08-04 18:17:40 +00001367- On Windows, the PyErr_Warn function is now exported from
1368 the Python dll again.
1369
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001370- Bug #1191458: tracing over for loops now produces a line event
1371 on each iteration. Fixing this problem required changing the .pyc
1372 magic number. This means that .pyc files generated before 2.5c1
1373 will be regenerated.
1374
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001375- Bug #1333982: string/number constants were inappropriately stored
1376 in the byte code and co_consts even if they were not used, ie
1377 immediately popped off the stack.
1378
Georg Brandle9462c72006-08-04 18:03:37 +00001379- Fixed a reference-counting problem in property().

1383-------
1384
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001385- Fix a bug in the ``compiler`` package that caused invalid code to be
1386 generated for generator expressions.
1387
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001388- The distutils version has been changed to 2.5.0. The change to
1389 keep it programmatically in sync with the Python version running
1390 the code (introduced in 2.5b3) has been reverted. It will continue
1391 to be maintained manually as static string literal.
1392
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001393- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001394 and this cannot be converted to the required C type, an exception is
1395 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001396 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001397
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001398- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001399 an exception.
1400
Tim Peterscbdd3502006-09-05 01:47:53 +00001401- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001402 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001403 workarounds for clocks with low resolution, to stop the code yielding
1404 duplicate UUIDs.
1405
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001406- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1407 before raising SystemExit, allowing IDLE to honor quit() and exit().
1408
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001409- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
1410
Georg Brandl7a1af772006-08-14 21:55:28 +00001411- Patch #1536071: trace.py should now find the full module name of a
1412 file correctly even on Windows.
1413
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001414- logging's atexit hook now runs even if the rest of the module has
1415 already been cleaned up.
1416
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001417- Bug #1112549, fix DoS attack on cgi.FieldStorage.
Guido van Rossum133f4e42006-08-10 17:42:50 +00001418
Neal Norwitzff4b63b2006-08-04 04:50:21 +00001419- Bug #1531405, format_exception no longer raises an exception if
1420 str(exception) raised an exception.
1421
Neil Schemenauer06ded092006-08-04 16:20:30 +00001422- Fix a bug in the ``compiler`` package that caused invalid code to be
1423 generated for nested functions.

1438
Thomas Heller86720042006-08-14 11:17:48 +00001439- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1440 uses the _as_parameter_ attribute when objects are passed to foreign
1441 function calls. The ctypes version number was changed to 1.0.1.
1442
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001443- Bug #1530559, struct.pack raises TypeError where it used to convert.
1444 Passing float arguments to struct.pack when integers are expected
1445 now triggers a DeprecationWarning.

1495Core and builtins
1496-----------------
1497
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001498- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001499 returned a long (see PEP 353).
1500
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001501- Bug #1515471: string.replace() accepts character buffers again.
1502
Neal Norwitz07aadb12006-07-30 06:55:48 +00001503- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1504 This provides the proper warning for struct.pack().
1505 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1506
Neal Norwitz0d62a062006-07-30 06:53:31 +00001507- Patch #1531113: Fix augmented assignment with yield expressions.
1508 Also fix a SystemError when trying to assign to yield expressions.
1509
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001510- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1511 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1512 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1513 excessive filesystem operations during imports.
1514
Tim Petersbc24eee2006-07-27 01:14:53 +00001515- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1516 operations on signed longs that are formally undefined by C.
1517 Unfortunately, at least one compiler now cares about that, so complicated
1518 the code to make that compiler happy again.
1519
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001520- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1521
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001522- Patch #1232023: Stop including current directory in search
1523 path on Windows.
1524
Neal Norwitze1fdb322006-07-21 05:32:28 +00001525- Fix some potential crashes found with failmalloc.
1526
Neal Norwitze7563102006-07-17 01:00:16 +00001527- Fix warnings reported by Klocwork's static analysis tool.
1528
Neal Norwitz84be93b2006-07-16 01:50:38 +00001529- Bug #1512814, Fix incorrect lineno's when code within a function
1530 had more than 255 blank lines.
1531
Georg Brandl9dceedb2006-07-12 15:31:17 +00001532- Patch #1521179: Python now accepts the standard options ``--help`` and
1533 ``--version`` as well as ``/?`` on Windows.
1534
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001535- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001536 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001537 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001538
Tim Peters112aad32006-07-19 00:03:19 +00001539- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001540 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001541 new ``sys._current_frames()`` returns a dictionary with one entry,
1542 mapping the faux "thread id" 0 to the current frame.
1543
Ronald Oussoren3075e162006-07-25 20:28:55 +00001544- Bug #1525447: build on MacOS X on a case-sensitive filesystem.

1548-------
1549
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001550- Correction of patch #1455898: In the mbcs decoder, set final=False
1551 for stream decoder, but final=True for the decode function.
1552
Georg Brandl07fec3a2006-08-01 18:49:24 +00001553- os.urandom no longer masks unrelated exceptions like SystemExit or
1554 KeyboardInterrupt.
1555
Tim Peters4643c2f2006-08-10 22:45:34 +00001556- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001557 shutil.copytree on Windows
1558
Georg Brandle34ac7c2006-07-30 11:07:23 +00001559- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1560 refers to file descriptors, not file objects.
1561
Tim Peterscbdd3502006-09-05 01:47:53 +00001562- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001563 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001564 #1513611, and probably others.
1565
Georg Brandledd9b0d2006-07-29 09:33:26 +00001566- Bug #1441397: The compiler module now recognizes module and function
1567 docstrings correctly as it did in Python 2.4.
1568
Tim Peters6f681472006-07-27 23:44:37 +00001569- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1570 lost that tests are sorted by name before being run. This rarely
1571 matters for well-written tests, but can create baffling symptoms if
1572 side effects from one test to the next affect outcomes. ``DocTestFinder``
1573 has been changed to sort the list of tests it returns.
1574
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001575- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001576 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001577
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001578- Bug #978833: Really close underlying socket in _socketobject.close.
1579
Georg Brandldb232dc2006-08-20 13:15:43 +00001580- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1581 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001582
Georg Brandlcf0c1722006-07-26 07:23:32 +00001583- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1584 to recursive calls and call it with the failing package name.
1585
Martin v. Löwis0b483032006-07-25 09:53:12 +00001586- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1587
Georg Brandlc13c34c2006-07-24 14:09:56 +00001588- Patch #1515343: Fix printing of deprecated string exceptions with a
1589 value in the traceback module.
1590
Greg Ward48fae7a2006-07-23 16:05:51 +00001591- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1592
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001593- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1594
Brett Cannoncaebe222006-07-18 04:41:36 +00001595- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1596 argument tuple. For arguments where zero is illegal, the value is forced to
1597 the minimum value that is correct. This is to support an undocumented but
1598 common way people used to fill in inconsequential information in the time
1599 tuple pre-2.4.
1600
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001601- Patch #1220874: Update the binhex module for Mach-O.
1602
Barry Warsawb110bad2006-07-21 14:51:07 +00001603- The email package has improved RFC 2231 support, specifically for
1604 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1605 (name*0=<blah>) parameter continuations. This may change the types of
1606 values returned from email.message.Message.get_param() and friends.
1607 Specifically in some cases where non-encoded continuations were used,
1608 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1609 will just return the string (since non-encoded continuations don't have
1610 charset and language parts).
1611
1612 Also, whereas % values were decoded in all parameter continuations, they are
1613 now only decoded in encoded parameter parts.
1614
Ronald Oussoren3075e162006-07-25 20:28:55 +00001615- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1616
1617- Bug #1517996: IDLE now longer shows the default Tk menu when a
1618 path browser, class browser or debugger is the frontmost window on MacOS X
1619
Barry Warsaw00decd72006-07-27 23:43:15 +00001620- Patch #1520294: Support for getset and member descriptors in types.py,
1621 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1622 of an object against these built-in types and more importantly, for getting
1623 their docstrings printed in the interactive interpreter's help() function.

1627-----------------
1628
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001629- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1630 a socket operation on a socket with a timeout, the exception will be
1631 caught correctly. Previously, the exception was not caught.
1632
Thomas Heller1393d6a2006-07-28 21:43:20 +00001633- Patch #1529514: The _ctypes extension is now compiled on more
1634 openbsd target platforms.
1635
Tim Peters9cab5932006-07-28 00:30:00 +00001636- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1637 a memory leak, affecting pickles and deep copies.
1638
Tim Petersbc24eee2006-07-27 01:14:53 +00001639- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1641
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001642- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1643
Thomas Hellerce049a02006-07-14 17:51:14 +00001644- Patch #1521817: Index range checking on ctypes arrays containing
1645 exactly one element enabled again. This allows iterating over these
1646 arrays, without the need to check the array size before.
1647
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001648- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001649 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001650 /dev/null in certain cases; this is now fixed.
1651
Thomas Heller47d7a062006-07-12 08:43:47 +00001652- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1653 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001654
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001655- Because of a misspelled preprocessor symbol, ctypes was always
1656 compiled without thread support; this is now fixed.
1657
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001658- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1659 methods now allow their database parameter to be None as the
1660 sleepycat API allows.
1661
Matt Flemingec926502006-07-28 11:27:27 +00001662- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1663 bluetooth API compared with Linux and FreeBSD.
1664
Brett Cannonf23ad3d2006-07-25 17:32:20 +00001665Tests

1667
1668- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1669 how long the test file should take to play. Now accepts taking 2.93 secs
1670 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1671
Georg Brandl4793aa32006-07-28 18:31:39 +00001672- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1673 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1674 run via ``regrtest.py``. Now they do.

1684- PythonLauncher now works correctly when the path to the script contains
1685 characters that are treated specially by the shell (such as quotes).
1686
1687- Bug #1527397: PythonLauncher now launches scripts with the working directory
1688 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001689 directory. That latter was an implementation accident and not what users

Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001701- Bug #1441486: The literal representation of -(sys.maxint - 1)
1702 again evaluates to a int object, not a long.
1703
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001704- Bug #1501934: The scope of global variables that are locally assigned
1705 using augmented assignment is now correctly determined.
1706
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001707- Bug #927248: Recursive method-wrapper objects can now safely

Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001710- Bug #1417699: Reject locale-specific decimal point in float()

1712
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001713- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1714 omit a default "error" argument for NULL pointer. This allows
1715 the parser to take a codec from cjkcodecs again.

1718
Neal Norwitz28746ab2006-07-09 22:14:42 +00001719- On 64 bit systems, int literals that use less than 64 bits are
1720 now ints rather than longs.
1721
Neal Norwitzed657552006-07-10 00:04:44 +00001722- Bug #1512814, Fix incorrect lineno's when code at module scope
1723 started after line 256.
1724
Tim Peters32a83612006-07-10 21:08:24 +00001725- New function ``sys._current_frames()`` returns a dict mapping thread
1726 id to topmost thread stack frame. This is for expert use, and is
1727 especially useful for debugging application deadlocks. The functionality
1728 was previously available in Fazal Majid's ``threadframe`` extension
1729 module, but it wasn't possible to do this in a wholly threadsafe way from
1730 an extension.

1739
Tim Peters32a83612006-07-10 21:08:24 +00001740- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001741 environment variable to be set in order to the SDK environment
1742 for finding the compiler, include files, etc.
1743
Martin v. Löwis388a8c22006-07-06 19:28:03 +00001744- Bug #1515998: Properly generate logical ids for files in bdist_msi.
1745
Nick Coghlan2d792252006-07-06 13:47:18 +00001746- warnings.py now ignores ImportWarning by default
1747
Thomas Woutersadd19112006-07-05 11:03:49 +00001748- string.Template() now correctly handles tuple-values. Previously,
1749 multi-value tuples would raise an exception and single-value tuples would
1750 be treated as the value they contain, instead.
1751
Martin v. Löwisede77f52006-07-03 13:01:35 +00001752- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1753 even if some data are received.
1754
Martin v. Löwis45482392006-07-03 12:28:58 +00001755- Bug #1267547: Put proper recursive setup.py call into the
1756 spec file generated by bdist_rpm.

1759 degrees and radians.
1760
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001761- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001762 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001763
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001764- Bug #1514703: Only setup canvas window in turtle when the canvas
1765 is created.
1766
Martin v. Löwis7596e832006-07-01 15:33:37 +00001767- Bug #1513223: .close() of a _socketobj now releases the underlying

1769
Fred Drake10497c82006-06-29 02:57:48 +00001770- Bug #1504333: Make sgmllib support angle brackets in quoted
1771 attribute values.
1772
1773- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1774 sgmllib ('[' and ']' were not accepted).
1775
Georg Brandl1be63af2006-06-28 20:23:25 +00001776- Fix a bug in the turtle module's end_fill function.
1777
Brett Cannon53ab5b72006-06-22 16:49:14 +00001778- Bug #1510580: The 'warnings' module improperly required that a Warning
1779 category be either a types.ClassType and a subclass of Warning. The proper
1780 check is just that it is a subclass with Warning as the documentation states.
1781
Georg Brandlad29e632006-06-21 17:45:17 +00001782- The compiler module now correctly compiles the new try-except-finally
1783 statement (bug #1509132).
1784
Neal Norwitz60373cd2006-06-22 06:30:50 +00001785- The wsgiref package is now installed properly on Unix.
1786
Vinay Sajip28e57612006-07-01 10:45:20 +00001787- A bug was fixed in logging.config.fileConfig() which caused a crash on
1788 shutdown when fileConfig() was called multiple times.
1789
Gerhard Häring762fbd32006-07-02 17:48:30 +00001790- The sqlite3 module did cut off data from the SQLite database at the first
1791 null character before sending it to a custom converter. This has been fixed
1792 now.
1793
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001794Extension Modules
1795-----------------
1796
Tim Peters112aad32006-07-19 00:03:19 +00001797- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1798 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1799 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001800
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001801- Assigning None to pointer type fields in ctypes structures possible
1802 overwrote the wrong fields, this is fixed now.
1803
1804- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1805 on non-Windows platforms.
1806
1807- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1808 integer or long, without range checking.
1809
1810- Patch #1517790: It is now possible to use custom objects in the ctypes
1811 foreign function argtypes sequence as long as they provide a from_param
1812 method, no longer is it required that the object is a ctypes type.
1813
1814- The '_ctypes' extension module now works when Python is configured
1815 with the --without-threads option.
1816
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001817- Bug #1513646: os.access on Windows now correctly determines write
1818 access, again.
1819
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001820- Bug #1512695: cPickle.loads could crash if it was interrupted with
1821 a KeyboardInterrupt.
1822
Neal Norwitza12aa882006-07-06 06:45:08 +00001823- Bug #1296433: parsing XML with a non-default encoding and
1824 a CharacterDataHandler could crash the interpreter in pyexpat.
1825
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001826- Patch #1516912: improve Modules support for OpenVMS.
1827

1829-----
1830
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001831- Automate Windows build process for the Win64 SSL module.
1832
Tim Peters32a83612006-07-10 21:08:24 +00001833- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001834 Previously, the slight difference could cause compilation errors of the
1835 'zlib' module on systems with more than one version of zlib.
1836
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001837- The MSI compileall step was fixed to also support a TARGETDIR
1838 with spaces in it.
1839
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001840- Bug #1517388: sqlite3.dll is now installed on Windows independent
1841 of Tcl/Tk.
1842
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001843- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001844 trying to be installed even though it's empty.

Neal Norwitzb15ac312006-06-29 04:10:08 +00001846Tests
1847-----
1848
1849- Call os.waitpid() at the end of tests that spawn child processes in order
1850 to minimize resources (zombies).
1851
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001852Documentation
1853-------------
1854
Nick Coghlan2d792252006-07-06 13:47:18 +00001855- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1856 documentation for the warnings module.
1857
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001858- Patch #1509163: MS Toolkit Compiler no longer available.
1859
Neal Norwitz56640df2006-07-10 02:36:41 +00001860- Patch #1504046: Add documentation for xml.etree.

Nick Coghlanc649ec52006-05-29 12:43:05 +00001863What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +00001864================================
Anthony Baxter51bcb682006-04-05 14:51:42 +00001865
Anthony Baxterd1136802006-06-19 12:04:15 +00001866*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +00001867
1868Core and builtins
1869-----------------
1870
Georg Brandla56b9152006-06-19 06:35:54 +00001871- Patch #1507676: Error messages returned by invalid abstract object operations
1872 (such as iterating over an integer) have been improved and now include the
1873 type of the offending object to help with debugging.
1874
Brett Cannonea3912b2006-06-13 21:46:41 +00001875- Bug #992017: A classic class that defined a __coerce__() method that returned
1876 its arguments swapped would infinitely recurse and segfault the interpreter.
1877
Neal Norwitz909eb122006-06-12 02:13:21 +00001878- Fix the socket tests so they can be run concurrently.
1879
Neal Norwitzb9845e72006-06-12 02:11:18 +00001880- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001881 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001882
Brett Cannon22565aa2006-06-09 22:31:23 +00001883- Bug #532646: object.__call__() will continue looking for the __call__
1884 attribute on objects until one without one is found. This leads to recursion
1885 when you take a class and set its __call__ attribute to an instance of the
1886 class. Originally fixed for classic classes, but this fix is for new-style.
1887 Removes the infinite_rec_3 crasher.
1888
Georg Brandl24250812006-06-09 18:45:48 +00001889- The string and unicode methods startswith() and endswith() now accept
1890 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1891
Brett Cannonde3b0522006-06-08 17:00:45 +00001892- Buffer objects, at the C level, never used the char buffer
1893 implementation even when the char buffer for the wrapped object was
1894 explicitly requested (originally returned the read or write buffer).
1895 Now a TypeError is raised if the char buffer is not present but is
1896 requested.
1897
Georg Brandlddbaa662006-06-04 21:56:52 +00001898- Patch #1346214: Statements like "if 0: suite" are now again optimized
1899 away like they were in Python 2.4.
1900
Georg Brandlb7c8f542006-05-27 12:30:25 +00001901- Builtin exceptions are now full-blown new-style classes instead of
1902 instances pretending to be classes, which speeds up exception handling
1903 by about 80% in comparison to 2.5a2.
1904
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001905- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1906 Unicode 4.1.
1907
Georg Brandlf4ef1162006-05-26 18:03:31 +00001908- Patch #921466: sys.path_importer_cache is now used to cache valid and
1909 invalid file paths for the built-in import machinery which leads to
1910 fewer open calls on startup.
1911
Tim Peters696cf432006-05-24 21:10:40 +00001912- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1913 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1914 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1915 the number of input digits (it was and remains linear-time for bases
1916 2, 4, 8, 16 and 32).
1917
Tim Petersb713ec22006-05-23 18:45:30 +00001918- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1919 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1920 an integer close to ``sys.maxint``. This was repaired by patch
1921 #1335972, which also gives a nice speedup.
1922
Richard Jonescebbefc2006-05-23 18:28:17 +00001923- Patch #1337051: reduced size of frame objects.
1924
1925- PyErr_NewException now accepts a tuple of base classes as its
1926 "base" parameter.
1927
Richard Jones7c88dcc2006-05-23 10:37:38 +00001928- Patch #876206: function call speedup by retaining allocated frame
1929 objects.
1930
Georg Brandl7b90e162006-05-18 07:01:27 +00001931- Bug #1462152: file() now checks more thoroughly for invalid mode
1932 strings and removes a possible "U" before passing the mode to the
1933 C library function.
1934
Neal Norwitz1004a532006-05-15 07:17:23 +00001935- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1936
Neal Norwitz373f0a72006-05-15 07:04:36 +00001937- Bug #1487966: Fix SystemError with conditional expression in assignment
1938
Martin v. Löwis879768d2006-05-11 13:28:43 +00001939- WindowsError now has two error code attributes: errno, which carries
1940 the error values from errno.h, and winerror, which carries the error
1941 values from winerror.h. Previous versions put the winerror.h values
1942 (from GetLastError()) into the errno attribute.
1943
Martin v. Löwis77736712006-05-04 05:51:03 +00001944- Patch #1475845: Raise IndentationError for unexpected indent.
1945
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001946- Patch #1479181: split open() and file() from being aliases for each other.
1947
Tim Peters44bd9862006-06-01 13:49:23 +00001948- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1949 methods were always silently ignored by dictionaries when comparing keys.
1950 They are now passed through (except when using the C API function
1951 ``PyDict_GetItem()``, whose semantics did not change).
1952
1953- Bug #1456209: In some obscure cases it was possible for a class with a
1954 custom ``__eq__()`` method to confuse dict internals when class instances
1955 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1956 No, you don't have any code that did this ;-)

1964
Brett Cannon6ee7d012006-06-08 16:23:04 +00001965- Change binascii.hexlify to accept a read-only buffer instead of only a char
1966 buffer and actually follow its documentation.
1967
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00001968- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
1969
Nick Coghlanc649ec52006-05-29 12:43:05 +00001970- Patch #1478788 (modified version): The functional extension module has
1971 been renamed to _functools and a functools Python wrapper module added.
1972 This provides a home for additional function related utilities that are
1973 not specifically about functional programming. See PEP 309.
1974
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00001975- Patch #1493701: performance enhancements for struct module.

1981
Andrew MacIntyre92913322006-06-13 15:04:24 +00001982- Patch #1454481: thread stack size is now tunable at runtime for thread
1983 enabled builds on Windows and systems with Posix threads support.
1984
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001985- On Win32, os.listdir now supports arbitrarily-long Unicode path names
1986 (up to the system limit of 32K characters).
1987
1988- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
1989 As a result, these functions now raise WindowsError instead of OSError.
1990
Tim Peters7a822da2006-05-25 21:50:17 +00001991- ``time.clock()`` on Win64 should use the high-performance Windows
1992 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
1993 Windows platforms).
1994
Neal Norwitz7a5fc282006-05-15 06:48:14 +00001995- Calling Tk_Init twice is refused if the first call failed as that
1996 may deadlock.
1997
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00001998- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
1999 accept it without potentially using an uninitialized pointer.
2000
2001- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
2002 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
2003 patch numbers 1494885 and 1494902]
Nick Coghlanc649ec52006-05-29 12:43:05 +00002004
Gregory P. Smith372b5832006-06-05 18:48:21 +00002005- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00002006 [pybsddb project SF patch number 1466734]
2007
Gregory P. Smith372b5832006-06-05 18:48:21 +00002008- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
2009 parameter is supplied. [SF pybsddb bug #1477863]
2010
Gregory P. Smith3c228b12006-06-05 23:59:37 +00002011- bsddb: the __len__ method of a DB object has been fixed to return correct
2012 results. It could previously incorrectly return 0 in some cases.
2013 Fixes SF bug 1493322 (pybsddb bug 1184012).
2014
Gregory P. Smithff7d9912006-06-08 05:17:08 +00002015- bsddb: the bsddb.dbtables Modify method now raises the proper error and
2016 aborts the db transaction safely when a modifier callback fails.
2017 Fixes SF python patch/bug #1408584.
2018
Gregory P. Smith506f7b52006-06-15 08:52:32 +00002019- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00002020 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00002021 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
2022 database calls that would previously deadlock. [SF python bug #775414]

2046 mime.types file for determining MIME types.
2047
Georg Brandl2605ca82006-06-14 06:08:31 +00002048- Bug #1339007: Shelf objects now don't raise an exception in their
2049 __del__ method when initialization failed.
2050
Martin v. Löwisd8251432006-06-14 05:21:04 +00002051- Patch #1455898: The MBCS codec now supports the incremental mode for
2052 double-byte encodings.
2053
Tim Peters43898b42006-06-14 04:09:25 +00002054- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
2055 guarantee that adjacent triples in the return list always describe
2056 non-adjacent blocks. Previously, a pair of matching blocks could end
2057 up being described by multiple adjacent triples that formed a partition
2058 of the matching pair.
2059
Greg Ward0e0c9f42006-06-11 16:24:11 +00002060- Bug #1498146: fix optparse to handle Unicode strings in option help,
2061 description, and epilog.
2062
Greg Wardd1c797e2006-06-11 14:42:41 +00002063- Bug #1366250: minor optparse documentation error.
2064
Greg Ward7f547402006-06-11 00:40:49 +00002065- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
2066 clarify docs.
2067
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00002068- The wsgiref package has been added to the standard library.
2069
Nick Coghlan676725d2006-06-08 13:54:49 +00002070- The functions update_wrapper() and wraps() have been added to the functools
2071 module. These make it easier to copy relevant metadata from the original
2072 function when writing wrapper functions.
2073
Tim Petersd6a9eef2006-06-05 01:48:21 +00002074- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
2075 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00002076
Martin v. Löwis3f767792006-06-04 19:36:28 +00002077- Patch #1359618: Speed up charmap encoder by using a trie structure
2078 for lookup.
2079
Tim Petersd609b1a2006-06-02 23:22:51 +00002080- The functions in the ``pprint`` module now sort dictionaries by key
2081 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
2082 if and only if its display required more than one line, although that
2083 wasn't documented. The new behavior increases predictability; e.g.,
2084 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
2085
Georg Brandlfd9a4b12006-05-29 20:57:01 +00002086- Patch #1497027: try HTTP digest auth before basic auth in urllib2

2095
Georg Brandlb89316f2006-05-17 15:51:16 +00002096- Patch #1180296: Two new functions were added to the locale module:
2097 format_string() to get the effect of "format % items" but locale-aware,
2098 and currency() to format a monetary number with currency sign.
2099
Georg Brandle3a25832006-05-17 14:56:04 +00002100- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
2101 and several features added, such as speed and geometry control.
2102
Georg Brandl49c8f4c2006-05-15 19:30:35 +00002103- Patch #1488881: add support for external file objects in bz2 compressed
2104 tarfiles.
2105
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002106- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
2107 stdout arguments, making it possible to redirect input and output
2108 for remote debugging.
2109
2110- Patch #1484695: Update the tarfile module to version 0.8. This fixes
2111 a couple of issues, notably handling of long file names using the
2112 GNU LONGNAME extension.
2113
2114- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
2115 new flag when ``name`` is already the name of an option flag.
2116
2117- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
2118 package.
2119
2120- Patch #1472854: make the rlcompleter.Completer class usable on non-
2121 UNIX platforms.
2122
2123- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
2124
Andrew M. Kuchling3fed2eb2006-06-09 16:44:40 +00002125- Bug #1472827: correctly escape newlines and tabs in attribute values in
2126 the saxutils.XMLGenerator class.

Neal Norwitz7a5fc282006-05-15 06:48:14 +00002156What's New in Python 2.5 alpha 2?

2158
2159*Release date: 27-APR-2006*
2160
2161Core and builtins
2162-----------------
2163
Thomas Heller1b046642006-04-18 18:51:06 +00002164- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2165 by converting these apis from macros into exported functions again:
2166
2167 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2168 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2169 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
2170 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
2171 PyRun_String Py_CompileString
2172
Martin v. Löwis45294a92006-04-18 06:24:08 +00002173- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2174
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002175- All uses of PyStructSequence_InitType have been changed to initialize
2176 the type objects only once, even if the interpreter is initialized
2177 multiple times.
2178
Neal Norwitz61546162006-04-14 05:20:28 +00002179- Bug #1454485, array.array('u') could crash the interpreter. This was
2180 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2181 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2182
2183- Py_UNICODE is unsigned. It was always documented as unsigned, but
2184 due to a bug had a signed value in previous versions.
2185
Tim Peters3a5e8b12006-04-11 01:44:07 +00002186- Patch #837242: ``id()`` of any Python object always gives a positive
2187 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2188 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002189 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002190 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002191
Tim Peters3a5e8b12006-04-11 01:44:07 +00002192 def __hash__(self):
2193 return id(self) # WRONG
2194
2195 because a hash result must be a (short) Python int but it was always
2196 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002197 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002198 was always usable as a hash value before this patch. That's no longer
2199 necessarily so.
2200
2201- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002202 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002203 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002204 #1454844)
2205
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002206- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2207 involving generators that have paused outside of any ``try`` or ``with``
2208 blocks. (In 2.5a1, a paused generator that was part of a reference
2209 cycle could not be garbage collected, regardless of whether it was
2210 paused in a ``try`` or ``with`` block.)

2223- Bug #1117761: bsddb.*open() no longer raises an exception when using
2224 the cachesize parameter.
2225
2226- Bug #1149413: bsddb.*open() no longer raises an exception when using
2227 a temporary db (file=None) with the 'n' flag to truncate on open.
2228
2229- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
2230 as older versions cause excessive test failures.
Gregory P. Smith7f5b6f42006-04-08 07:10:51 +00002231
Armin Rigoa9017c32006-04-19 11:50:27 +00002232- Patch #1062014: AF_UNIX sockets under Linux have a special

2240 abusing errno.
2241
Tim Peters711bf302006-04-25 03:31:36 +00002242- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2243 a doctest to be skipped (the code is not run, and the expected output
2244 or exception is ignored).
2245
Nick Coghlanda2268f2006-04-24 04:37:15 +00002246- Fixed contextlib.nested to cope with exceptions being raised and
2247 caught inside exit handlers.
2248
Greg Wardab05edc2006-04-23 03:47:58 +00002249- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2250 hex, octal, or binary; add ``append_const`` action; keep going if
2251 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2252 added ``epilog`` for better help generation).
2253
Tim Peters21fbd572006-04-21 21:18:10 +00002254- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2255 called from a thread spawned as a side effect of importing a module.
2256
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002257- The pydoc module now supports documenting packages contained in
2258 .zip or .egg files.
2259
2260- The pkgutil module now has several new utility functions, such
2261 as ``walk_packages()`` to support working with packages that are either
2262 in the filesystem or zip files.
2263
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002264- The mailbox module can now modify and delete messages from
2265 mailboxes, in addition to simply reading them. Thanks to Gregory
2266 K. Johnson for writing the code, and to the 2005 Google Summer of
2267 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002268
Tim Petersc7605f22006-04-17 21:12:33 +00002269- The ``__del__`` method of class ``local`` in module ``_threading_local``
2270 returned before accomplishing any of its intended cleanup.
2271
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002272- Patch #790710: Add breakpoint command lists in pdb.

2280
Phillip J. Eby47032112006-04-11 01:07:43 +00002281- The warnings, linecache, inspect, traceback, site, and doctest modules

Martin v. Löwis4be4e652006-04-17 19:25:49 +00002298- The Makefile now has a reindent target, which runs reindent.py on
2299 the library.

2306 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002307 specified. (Can be overridden by explicitly setting LINKCC.) Decouple

Anthony Baxter51bcb682006-04-05 14:51:42 +00002318Tests
2319-----
2320
Nick Coghlanda2268f2006-04-24 04:37:15 +00002321- test_contextlib now checks contextlib.nested can cope with exceptions
2322 being raised and caught inside exit handlers.

2325
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002326- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2327 it separately and by hand. It also wasn't cleaning up its changes to
2328 the current Decimal context.
2329
Thomas Woutersabd08882006-04-26 15:53:30 +00002330- regrtest.py now has a -M option to run tests that test the new limits of
2331 containers, on 64-bit architectures. Running these tests is only sensible
2332 on 64-bit machines with more than two gigabytes of memory. The argument
2333 passed is the maximum amount of memory for the tests to use.

2342-------------
2343
Tim Petersb06d28c2006-05-12 01:57:59 +00002344- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2345
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002346- PEP 343: Added Context Types section to the library reference
2347 and attempted to bring other PEP 343 related documentation into
2348 line with the implementation and/or python-dev discussions.
2349
Tim Peters8dc73d22006-04-24 02:03:16 +00002350- Bug #1337990: clarified that ``doctest`` does not support examples
2351 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002359Core and builtins
2360-----------------
2361
Nick Coghlan43832302006-04-23 17:04:07 +00002362- PEP 338: -m command line switch now delegates to runpy.run_module
2363 allowing it to support modules in packages and zipfiles
2364
Martin v. Löwisc661b882006-04-20 04:54:23 +00002365- On Windows, .DLL is not an accepted file name extension for
2366 extension modules anymore; extensions are only found if they
2367 end in .PYD.
2368
Martin v. Löwisea62d252006-04-03 10:56:49 +00002369- Bug #1421664: sys.stderr.encoding is now set to the same value as
2370 sys.stdout.encoding.
2371
Neal Norwitz92e212f2006-04-03 04:48:37 +00002372- __import__ accepts keyword arguments.
2373
Georg Brandlccadf842006-03-31 18:54:53 +00002374- Patch #1460496: round() now accepts keyword arguments.
2375
Anthony Baxter262c00a2006-03-30 10:53:17 +00002376- Fixed bug #1459029 - unicode reprs were double-escaped.
2377
Hye-Shik Changd478f342006-03-23 12:32:36 +00002378- Patch #1396919: The system scope threads are reenabled on FreeBSD
2379 5.4 and later versions.
2380
Neal Norwitze98ccf62006-03-23 05:39:47 +00002381- Bug #1115379: Compiling a Unicode string with an encoding declaration
2382 now gives a SyntaxError.
2383
Georg Brandlabd1ff82006-03-18 07:59:59 +00002384- Previously, Python code had no easy way to access the contents of a
2385 cell object. Now, a ``cell_contents`` attribute has been added
2386 (closes patch #1170323).
2387
Tim Peterscf79aac2006-03-16 01:14:46 +00002388- Patch #1123430: Python's small-object allocator now returns an arena to
2389 the system ``free()`` when all memory within an arena becomes unused
2390 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2391 freed. Some applications will see a drop in virtual memory size now,
2392 especially long-running applications that, from time to time, temporarily
2393 use a large number of small objects. Note that when Python returns an
2394 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002395 platform C library will in turn return that memory to the operating system.
2396 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002397 appears to be effective at least on Microsoft C and gcc-based systems.
2398 Thanks to Evan Jones for hard work and patience.
2399
Georg Brandl533ff6f2006-03-08 18:09:27 +00002400- Patch #1434038: property() now uses the getter's docstring if there is
2401 no "doc" argument given. This makes it possible to legitimately use
2402 property() as a decorator to produce a read-only property.
2403
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002404- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2405 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2406 of requiring an int or long in slicing and a few other contexts, enabling
2407 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2408
Neal Norwitz995acdf2006-03-07 05:01:00 +00002409- Fixed various bugs reported by Coverity's Prevent tool.
2410
Brett Cannonbf364092006-03-01 04:25:17 +00002411- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2412 new exception base class, BaseException, which has a new message attribute.
2413 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2414 Raising a string exception now raises a DeprecationWarning.
2415
Thomas Woutersfb609f42006-02-28 16:37:25 +00002416- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2417 explicitly relative, using 'from .module import name' to mean 'from the same
2418 package as this module is in. Imports without dots still default to the
2419 old relative-then-absolute, unless 'from __future__ import
2420 absolute_import' is used.
2421
Brett Cannona7446e32006-02-27 23:39:10 +00002422- Properly check if 'warnings' raises an exception (usually when a filter set
2423 to "error" is triggered) when raising a warning for raising string
2424 exceptions.
2425
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002426- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002427 The name was removed from Include/code.h.
2428
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002429- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002430
Guido van Rossum1968ad32006-02-25 22:38:04 +00002431- Patch 1433928:
2432 - The copy module now "copies" function objects (as atomic objects).
2433 - dict.__getitem__ now looks for a __missing__ hook before raising
2434 KeyError.
2435
Tim Peters84ef21c2006-02-28 20:39:06 +00002436- PEP 343: with statement implemented. Needs ``from __future__ import
2437 with_statement``. Use of 'with' as a variable will generate a warning.
2438 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002439 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002440 The following objects have __context__ methods:
2441 - The built-in file type.
2442 - The thread.LockType type.
2443 - The following types defined by the threading module:
2444 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2445 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002446
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002447- Fix the encodings package codec search function to only search
2448 inside its own package. Fixes problem reported in patch #1433198.
2449
2450 Note: Codec packages should implement and register their own
2451 codec search function. PEP 100 has the details.
2452
Tim Peters9ea89d22006-06-04 03:26:02 +00002453- PEP 353: Using ``Py_ssize_t`` as the index type.
2454
2455- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2456 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2457 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2458 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2459 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002460
Neal Norwitzfc76d632006-01-10 06:03:13 +00002461- Patch #1400181, fix unicode string formatting to not use the locale.
2462 This is how string objects work. u'%f' could use , instead of .
2463 for the decimal point. Now both strings and unicode always use periods.
2464
Neal Norwitz671b9e32006-01-09 07:07:12 +00002465- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2466 configure would break checking curses.h.
2467
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002468- Bug #959576: The pwd module is now builtin. This allows Python to be
2469 built on UNIX platforms without $HOME set.
2470
Neal Norwitzc10978f2005-12-19 06:07:16 +00002471- Bug #1072182, fix some potential problems if characters are signed.
2472
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002473- Bug #889500, fix line number on SyntaxWarning for global declarations.
2474
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002475- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2476
Neal Norwitze7214a12005-12-18 05:03:17 +00002477- Support for converting hex strings to floats no longer works.
2478 This was not portable. float('0x3') now raises a ValueError.
2479
Barry Warsaw2a38a862005-12-18 01:27:35 +00002480- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002481 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002482 is now displayed in interactive prompt banner.
2483
Georg Brandlfa166682005-12-17 21:45:17 +00002484- Implementation of PEP 341 - Unification of try/except and try/finally.
2485 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002486 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002487
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002488- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2489 now encodes backslash correctly.
2490
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002491- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2492
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002493- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002494 and long longs.
2495
Neal Norwitz67715f02005-11-09 06:59:35 +00002496- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002497 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002498 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002499
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002500- Replaced most Unicode charmap codecs with new ones using the
2501 new Unicode translate string feature in the builtin charmap
2502 codec; the codecs were created from the mapping tables available
2503 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2504 encodings now include a mapping for the Apple logo)
2505
Tim Peterse3547fd2005-12-16 23:13:57 +00002506- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002507
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002508- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002509
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002510- A new AST parser implementation was completed. The abstract
2511 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002512 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002513
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002514- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002515 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2516
Neal Norwitz708e51a2005-10-03 04:48:15 +00002517- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2518
Neal Norwitz11bd1192005-10-03 00:54:56 +00002519- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2520 Provide a warning when a directory is passed on the command line.
2521
Neal Norwitz40d37812005-10-02 01:48:49 +00002522- Fix segfault with invalid coding.
2523
2524- SF bug #772896: unknown encoding results in MemoryError.
2525
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002526- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002527 supported a __len__() method which evaluated to False when the iterator
2528 was empty.
2529
Guido van Rossum630db602005-09-20 18:49:54 +00002530- On 64-bit platforms, when __len__() returns a value that cannot be
2531 represented as a C int, raise OverflowError.
2532
Skip Montanarof8948ca2005-09-19 03:54:46 +00002533- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002534 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002535
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002536- SF bug #893549: parsing keyword arguments was broken with a few format
2537 codes.
2538
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002539- Changes donated by Elemental Security to make it work on AIX 5.3
2540 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2541 bug #105470: test_pwd fails on 64bit system (Opteron).
2542
Guido van Rossum539c6622005-09-14 17:49:54 +00002543- Changes donated by Elemental Security to make it work on HP-UX 11 on
2544 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2545
Georg Brandl4550b8d2005-08-26 06:43:52 +00002546- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002547 (fixes bug #1119418).
2548
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002549- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2550
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002551- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2552 exceptions that cause a function to exit.
2553
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002554- The implementation of set() and frozenset() was revised to use its
2555 own internal data structure. Memory consumption is reduced by 1/3
2556 and there are modest speed-ups as well. The API is unchanged.
2557
Tim Petersde7990b2005-07-17 23:45:23 +00002558- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2559
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002560- SF bug #1229429: PyObject_CallMethod failed to decrement some
2561 reference counts in some error exit cases.
2562
Tim Petersecc6e6a2005-07-10 22:30:55 +00002563- SF bug #1185883: Python's small-object memory allocator took over
2564 a block managed by the platform C library whenever a realloc specified
2565 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002566 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002567 portable way to copy data from the C-managed block into Python's
2568 small-object space without risking a memory fault. Python's small-object
2569 realloc now leaves such blocks under the control of the platform C
2570 realloc.
2571
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002572- SF bug #1232517: An overflow error was not detected properly when
2573 attempting to convert a large float to an int in os.utime().
2574
Raymond Hettinger3296e692005-06-29 23:29:56 +00002575- SF bug #1224347: hex longs now print with lowercase letters just
2576 like their int counterparts.
2577
Michael W. Hudson188d4362005-06-20 16:52:57 +00002578- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2579 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2580 interpreter states; back out that fix and do a better job (see
2581 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2582 for a longer write-up of the problem).
2583
Michael W. Hudsondf888462005-06-03 14:41:55 +00002584- SF patch #1180995: marshal now uses a binary format by default when
2585 serializing floats.
2586
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002587- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2588 the routines that promise to produce IEEE 754 binary representations
2589 of floats now simply copy bytes around.
2590
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002591- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2592 278.
2593
Brett Cannonc3647ac2005-04-26 03:45:26 +00002594- patch #1109424: int, long, float, complex, and unicode now check for the
2595 proper magic slot for type conversions when subclassed. Previously the
2596 magic slot was ignored during conversion. Semantics now match the way
2597 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002598 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002599 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002600 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002601
Barry Warsawc8d907c2005-04-19 23:43:40 +00002602- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2603 NULL, now raise an AttributeError when attempting to set or delete the
2604 attribute. Previously a TypeError was raised, but this was inconsistent
2605 with the equivalent pure-Python implementation.
2606
Michael W. Hudson774479c2005-04-18 08:46:17 +00002607- It is now safe to call PyGILState_Release() before
2608 PyEval_InitThreads() (note that if there is reason to believe there
2609 are multiple threads around you still must call PyEval_InitThreads()
2610 before using the Python API; this fix is for extension modules that
2611 have no way of knowing if Python is multi-threaded yet).
2612
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002613- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2614 disabled caused a crash.
2615
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002616- Bug #1165306: instancemethod_new allowed the creation of a method
2617 with im_class == im_self == NULL, which caused a crash when called.
2618
Tim Petersecc6e6a2005-07-10 22:30:55 +00002619- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002620 fixes the crash seen in bug #1165761
2621
Raymond Hettinger96229b12005-03-11 06:49:40 +00002622- Added two new builtins, any() and all().
2623
Brett Cannon409d8f22005-03-05 06:47:57 +00002624- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002625 (e.g., ``class C(): pass`` is no longer a syntax error).
2626 Patch #1176012 added support to the 'parser' module and 'compiler' package
2627 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002628
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002629- Patch #1115086: Support PY_LONGLONG in structmember.

2632 returning None.
2633
Tim Petersecc6e6a2005-07-10 22:30:55 +00002634- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002635 ('\') with a specific error message.
2636
Martin v. Löwisff232d72005-03-03 09:24:38 +00002637- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2638
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002639- Bug #1124295: the __name__ attribute of file objects was
2640 inadvertently made inaccessible in restricted mode.
2641
Tim Petersecc6e6a2005-07-10 22:30:55 +00002642- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002643 an ferror() call.
2644
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002645- min() and max() now support key= arguments with the same meaning as in
2646 list.sort().
2647
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002648- The peephole optimizer now performs simple constant folding in expressions:
2649 (2+3) --> (5).
2650
Raymond Hettingera422c342005-01-11 03:03:27 +00002651- set and frozenset objects can now be marshalled. SF #1098985.
2652
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002653- Bug #1077106: Poor argument checking could cause memory corruption
2654 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002655
Jeremy Hyltonab630502005-02-04 18:44:06 +00002656- The parser did not complain about future statements in illegal
2657 positions. It once again reports a syntax error if a future
2658 statement occurs after anything other than a doc string.
2659
Neil Schemenauercf52c072005-08-12 17:34:58 +00002660- Change the %s format specifier for str objects so that it returns a
2661 unicode instance if the argument is not an instance of basestring and
2662 calling __str__ on the argument returns a unicode instance.
2663
Tim Petersf4e69282006-02-27 17:15:31 +00002664- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2665 current thread state when the auto-GIL-state machinery knows about
2666 it (since the thread state is being deleted, continuing to remember it
2667 can't help, but can hurt if another thread happens to get created with
2668 the same thread id).

2699
Neal Norwitzb62c4332006-03-04 18:35:47 +00002700- The timing module is no longer built by default. It was deprecated

Nick Coghlan43832302006-04-23 17:04:07 +00002864- PEP 338: new module runpy defines a run_module function to support
2865 executing modules which provide access to source code or a code object
2866 via the PEP 302 import mechanisms.
2867
Anthony Baxter93f5b932006-04-03 08:05:07 +00002868- The email module's parsedate_tz function now sets the daylight savings

2876 in attribute values.
2877
Anthony Baxterc51ee692006-04-01 00:57:31 +00002878- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002879 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002880 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002881 module will not be built.
2882
Tim Petersc17976e2006-04-01 00:26:53 +00002883- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2884 aren't officially supported here, and trying to use them will probably
2885 raise an exception some day. But dicts have been allowed, and "mostly
2886 worked", so support for them won't go away without warning.
2887
Georg Brandl338ef7d2006-03-31 18:42:16 +00002888- Bug #1445068: getpass.getpass() can now be given an explicit stream

2900 to make it easier to monitor when daemon threads have completed
2901 processing all enqueued tasks. Patch #1455676.
2902

2906
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002907- email 4.0 package now integrated. This is largely the same as the email 3.0
2908 package that was included in Python 2.3, except that PEP 8 module names are
2909 now used (e.g. mail.message instead of email.Message). The MIME classes
2910 have been moved to a subpackage (e.g. email.mime.text instead of
2911 email.MIMEText). The old names are still supported for now. Several
2912 deprecated Message methods have been removed and lots of bugs have been
2913 fixed. More details can be found in the email package documentation.
2914
Walter Dörwald40108c92006-03-27 08:15:44 +00002915- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2916 (a subclass of tuple) that provides incremental decoders and encoders
2917 (a way to use stateful codecs without the stream API). Python functions
2918 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2919 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2920 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002921
Walter Dörwald067db482006-03-15 22:17:27 +00002922- Patch #1359365: Calling next() on a closed StringIO.String object raises
2923 a ValueError instead of a StopIteration now (like file and cString.String do).
2924 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2925 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002926

Tim Peterse3547fd2005-12-16 23:13:57 +00002999 SHA1, 224, 256, 384, and 512. Note that recent developments make the
3000 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
3001 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
3002 Ronald L. Rivest offered this advice for Python:
3003
3004 "The consensus of researchers in this area (at least as
3005 expressed at the NIST Hash Function Workshop 10/31/05),
3006 is that SHA-256 is a good choice for the time being, but
3007 that research should continue, and other alternatives may
3008 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00003009
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00003010- Added a subset of Fredrik Lundh's ElementTree package. Available

Raymond Hettinger267b8682005-03-27 10:47:39 +00003126- decimal operator and comparison methods now return NotImplemented
3127 instead of raising a TypeError when interacting with other types. This
3128 allows other classes to implement __radd__ style methods and have them
3129 work as expected.
3130
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00003131- Bug #1163325: Decimal infinities failed to hash. Attempting to
3132 hash a NaN raised an InvalidOperation instead of a TypeError.
3133
Tim Petersecc6e6a2005-07-10 22:30:55 +00003134- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00003135 stream compression; add, for symmetry reasons, r:* as a synonym of r.
3136
Martin v. Löwis00a73e72005-03-04 19:40:34 +00003137- Patch #1043890: Add extractall method to tarfile.
3138
Martin v. Löwisc72dd382005-03-04 13:50:17 +00003139- Patch #1075887: Don't require MSVC in distutils if there is nothing
3140 to build.
3141
Martin v. Löwis637431b2005-03-03 23:12:42 +00003142- Patch #1103407: Properly deal with tarfile iterators when untarring
3143 symbolic links on Windows.
3144
Tim Petersecc6e6a2005-07-10 22:30:55 +00003145- Patch #645894: Use getrusage for computing the time consumption in
Martin v. Löwisa4dac402005-03-03 11:39:45 +00003146 profile.py if available.
3147
Martin v. Löwisdf37c8c2005-03-03 11:08:03 +00003148- Patch #1046831: Use get_python_version where appropriate in sysconfig.py.
3149
Martin v. Löwisc5574e82005-03-03 10:57:37 +00003150- Patch #1117454: Remove code to special-case cookies without values
3151 in LWPCookieJar.
3152
Martin v. Löwis4ea3ead2005-03-03 10:48:12 +00003153- Patch #1117339: Add cookielib special name tests.
3154
Martin v. Löwise869eb12005-03-03 09:46:07 +00003155- Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
3156
Martin v. Löwisf2a8d632005-03-03 08:35:22 +00003157- Patch #1110248: SYNC_FLUSH the zlib buffer for GZipFile.flush.
3158
Martin v. Löwisdf241532005-03-03 08:17:42 +00003159- Patch #1107973: Allow to iterate over the lines of a tarfile.ExFileObject.
3160
Martin v. Löwis8ed338a2005-03-03 08:12:27 +00003161- Patch #1104111: Alter setup.py --help and --help-commands.
3162
Martin v. Löwis4afe1542005-03-01 08:09:28 +00003163- Patch #1121234: Properly cleanup _exit and tkerror commands.
3164
Martin v. Löwisc2a0ac22005-02-24 20:22:10 +00003165- Patch #1049151: xdrlib now unpacks booleans as True or False.
3166
Raymond Hettingerbab41432005-02-05 01:31:19 +00003167- Fixed bug in a NameError bug in cookielib. Patch #1116583.
3168
Guido van Rossumd0641422005-02-03 15:01:24 +00003169- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
3170 disables recursive traversal through instance attributes, which can
3171 be exploited in various ways.
3172
Tim Peterse3547fd2005-12-16 23:13:57 +00003173- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00003174 flags on the HTTP listening socket.
3175
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00003176- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
3177 Fixed by reading the HTTP body in chunks instead of one big socket.read().
3178
Fred Drakefbdeaad2006-07-29 16:56:15 +00003179- Patches #893642, #1039083: add allow_none, encoding arguments to
3180 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00003181
Martin v. Löwis1d11de62005-01-29 13:29:23 +00003182- Bug #1110478: Revert os.environ.update to do putenv again.
3183
Thomas Hellerd6c6e222005-01-20 19:20:16 +00003184- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
3185
Martin v. Löwis22b457e2005-01-16 08:40:58 +00003186- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
3187
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003188- Enhancements to the csv module:
3189
3190 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003191 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003192 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003193 + Dialect parameter parsing has been re-implemented to improve error
3194 reporting.
3195 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3196 dictates.
3197 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003198 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003199 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003200 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3201 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003202 + reader now allows \r characters to be quoted (previously it only allowed
3203 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003204 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003205 + Dialect classes passed to the module are no longer instantiated by
3206 the module before being parsed (the former validation scheme required
3207 this, but the mechanism was unreliable).
3208 + The dialect registry now contains instances of the internal
3209 C-coded dialect type, rather than references to python objects.
3210 + the internal c-coded dialect type is now immutable.
3211 + register_dialect now accepts the same keyword dialect specifications
3212 as the reader and writer, allowing the user to register dialects
3213 without first creating a dialect class.
3214 + a configurable limit to the size of parsed fields has been added -
3215 previously, an unmatched quote character could result in the entire
3216 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003217 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003218 the parser field size limit (returning the former limit). The initial
3219 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003220 + A line_num attribute has been added to the reader object, which tracks
3221 the number of lines read from the source iterator. This is not
3222 the same as the number of records returned, as records can span
3223 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003224 + reader and writer objects were not being registered with the cyclic-GC.
3225 This has been fixed.
3226
Brett Cannone6539c42005-01-08 02:43:53 +00003227- _DummyThread objects in the threading module now delete self.__block that is
3228 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3229 lock primitives tend to be limited in number and thus should not be wasted on
3230 a _DummyThread object. Fixes bug #1089632.
3231
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003232- The imghdr module now detects Exif files.
3233
Raymond Hettinger6065d322004-12-20 23:51:53 +00003234- StringIO.truncate() now correctly adjusts the size attribute.
3235 (Bug #951915).
3236
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003237- locale.py now uses an updated locale alias table (built using
3238 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3239 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003240 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003241
Raymond Hettinger3557f422004-12-07 12:02:02 +00003242- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3243
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003244- the pickle module no longer accepts the deprecated None option in the
3245 args tuple returned by __reduce__().
3246
Brett Cannon84667c02004-12-07 03:25:18 +00003247- optparse now optionally imports gettext. This allows its use in setup.py.
3248
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003249- the pickle module no longer uses the deprecated bin parameter.
3250
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003251- the shelve module no longer uses the deprecated binary parameter.
3252
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003253- the pstats module no longer uses the deprecated ignore() method.
3254
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003255- the filecmp module no longer uses the deprecated use_statcache argument.
3256
Raymond Hettinger664347b2004-12-04 21:21:53 +00003257- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3258 extended or overridden by subclasses. Formerly, the subclassed method would
3259 be ignored by the rest of the module. (Bug #1078905).
3260
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003261- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003262 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003263
Walter Dörwald36733692004-12-22 12:50:50 +00003264- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3265 once when a size argument is given. This prevents a buffer overflow in the
3266 tokenizer with very long source lines.
3267
Barry Warsaw538561e2006-01-01 21:48:54 +00003268- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3269 immediately after creating the object, without any intervening
3270 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003271
Skip Montanaro05885812005-01-16 20:48:27 +00003272- The reconvert.quote function can now emit triple-quoted strings. The
3273 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003274
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003275- ``UserString.MutableString`` now supports negative indices in
3276 ``__setitem__`` and ``__delitem__``
3277
Greg Ward40407942005-03-05 02:53:17 +00003278- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3279 correctly.
3280
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003281- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3282 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3283 character even if the user has passed a size parameter to get a proper
3284 line ending. Remove the special handling of a "\r\n" that has been split
3285 between two lines.
3286
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003287- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3288 about illegal code points. The codec now supports PEP 293 style error
3289 handlers.
3290
Walter Dörwald78a78b02005-09-01 12:04:29 +00003291- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003292 from the input stream, so that the output is a byte string in the correct
3293 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003294
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003295- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3296 considering it exactly like a '*'.
3297
Walter Dörwald007f8df2005-10-09 19:42:27 +00003298- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3299 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003300
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003301- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3302
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003303- Patch #1413711: Certain patterns of differences were making difflib
3304 touch the recursion limit.
3305
Walter Dörwald58917a62006-03-31 15:26:22 +00003306- Bug #947906: An object oriented interface has been added to the calendar
3307 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003308 called as a script (e.g. via ``python -mcalendar``). Localized month and
3309 weekday names can be ouput (even if an exotic encoding is used) using
3310 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003311

3313-----
3314
Neal Norwitz602d3392006-03-31 08:21:40 +00003315- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
3316 by using -mieee gcc option.
3317
Martin v. Löwis86d66262006-02-17 08:40:11 +00003318- Patch #1432345: Make python compile on DragonFly.
3319
Martin v. Löwis856bf9a2006-02-14 20:42:55 +00003320- Build support for Win64-AMD64 was added.
3321
Martin v. Löwisa55e55e2006-02-11 15:55:14 +00003322- Patch #1428494: Prefer linking against ncursesw over ncurses library.
3323
Martin v. Löwisfd9a72a2006-01-08 10:07:33 +00003324- Patch #881820: look for openpty and forkpty also in libbsd.
3325
Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003326- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3327 The zlib module is now builtin on Windows.
3328
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003329- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3330
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003331- Bug #1189330: configure did not correctly determine the necessary
3332 value of LINKCC if python was built with GCC 4.0.
3333
Trent Mick8321b422005-07-26 02:29:21 +00003334- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3335 vulnerability in zlib 1.2.1 and 1.2.2.
3336
Brett Cannon08cd5982005-04-24 22:26:38 +00003337- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3338 flags that change binary compatibility. Changes were also made to
3339 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003340 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003341
Bob Ippolitoed233462005-03-29 13:47:59 +00003342- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3343 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3344 no longer exists). This configure patch makes things right.
3345
Martin v. Löwise2713be2005-03-08 15:03:08 +00003346- Bug #1158607: Build with --disable-unicode again.
3347
Brett Cannon46d96232005-02-16 00:07:19 +00003348- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3349 defined. Discovered as a result of not being able to build on OS X.
3350
Brett Cannon516592f2004-12-07 00:42:59 +00003351- setup.py now uses the directories specified in LDFLAGS using the -L option
3352 and in CPPFLAGS using the -I option for adding library and include
3353 directories, respectively, for compiling extension modules against. This has
3354 led to the core being compiled using the values in CPPFLAGS. It also removes
3355 the need for the special-casing of both DarwinPorts and Fink for darwin since
3356 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3357 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3358 Fink, ``-I/opt/local/include`` for DarwinPorts).
3359
Brett Cannon43802422005-02-10 20:48:03 +00003360- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3361 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3362 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3363 Closes bug #1096244. Thanks Gregory Bond.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003365C API
3366-----
3367
Tim Petersc9d78aa2006-03-26 23:27:58 +00003368- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3369 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3370 is obtained via the ``PyObject_`` family, it must be released via the
3371 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3372 always been officially true, but when Python's small-object allocator was
3373 introduced, an attempt was made to cater to a few extension modules
3374 discovered at the time that obtained memory via ``PyObject_New`` but
3375 released it via ``PyMem_DEL``. It's years later, and if such code still
3376 exists it will fail now (probably with segfaults, but calling wrong
3377 low-level memory management functions can yield many symptoms).
3378
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003379- Added a C API for set and frozenset objects.
3380
Raymond Hettinger66517482004-12-03 11:45:13 +00003381- Removed PyRange_New().
3382
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003383- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3384 mapping argument now. This string is used as a mapping table. Byte values
3385 greater than the length of the string and 0xFFFE are treated as undefined
3386 mappings.
