164
Guido van Rossumaa975432008-04-10 22:43:58 +0000165- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
166 having a self-referential tuple, which is possible from C code. Nor did
167 object's tp_str consider that a type's tp_str could do something that could
168 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
169 respectively, fixed the issues. (Backport of r58288 from trunk.)

178 \Uxxxxxxxx did not accept values outside the Basic Multilingual Plane. This
179 affected raw unicode literals and the 'raw-unicode-escape' codec. Now
180 UTF-16 surrogates are generated in this case, like normal unicode literals
181 and the 'unicode-escape' codec.
182
Neal Norwitzb3635f92008-03-18 04:17:36 +0000183- Issue #2321: use pymalloc for unicode object string data to reduce

191 less than zero will now raise a SystemError and return NULL to indicate a
192 bug in the calling C code.
193
Gregory P. Smith9aa040d2008-06-02 00:07:25 +0000194- Issue #2588, #2589: Fix potential integer underflow and overflow
195 conditions in the PyOS_vsnprintf C API function.

Gregory P. Smithcae7f882008-09-07 06:44:12 +0000197- Issue #1204: The configure script now tests for additional libraries
198 that may be required when linking against readline. This fixes issues
199 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

1229
Neal Norwitz0bcafac2006-09-11 08:51:17 +00001230- Make _PyGILState_NoteThreadState() static, it was not used anywhere
1231 outside of pystate.c and should not be necessary.
1232
Brett Cannon19d76c52006-09-09 07:18:44 +00001233- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
1234 allows calling unicode() on exceptions classes directly to succeed.
1235
Georg Brandlecab6232006-09-06 06:47:02 +00001236- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
1237 Also make sure that every exception class has __module__ set to
1238 'exceptions'.
1239
Georg Brandl37a9e572006-09-06 06:09:34 +00001240- Bug #1550983: emit better error messages for erroneous relative

Neal Norwitz29a5fdb2006-09-05 02:21:38 +00001251- The return tuple from str.rpartition(sep) is (tail, sep, head) where
1252 head is the original string if sep was not found.
1253
Neal Norwitz3b3aae02006-09-05 03:56:01 +00001254- Bug #1520864: unpacking singleton tuples in list comprehensions and
1255 generator expressions (x for x, in ... ) works again. Fixing this problem
1256 required changing the .pyc magic number. This means that .pyc files
1257 generated before 2.5c2 will be regenerated.

Neal Norwitz24b6f202006-09-05 04:43:56 +00001372- Fix infinite recursion when subclassing long and overriding __hash__.
1373
1374- Fix concatenation (+=) of long strings.
1375
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001376- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001377 compared equal or unequal to a string and a UnicodeDecodeError
1378 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001379
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001380 Instead, the equal (==) and unequal (!=) comparison operators will
1381 now issue a UnicodeWarning and interpret the two objects as
1382 unequal. The UnicodeWarning can be filtered as desired using
1383 the warning framework, e.g. silenced completely, turned into an
1384 exception, logged, etc.
1385
1386 Note that compare operators other than equal and unequal will still
1387 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001388
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001389- Fix segfault when doing string formatting on subclasses of long.
1390
1391- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1392 with new-style classes.
1393
1394- Fix bug related to __len__ functions returning negative values with
1395 classic classes.
1396
1397- Patch #1538606, Fix __index__() clipping. There were some problems
1398 discovered with the API and how integers that didn't fit into Py_ssize_t
1399 were handled. This patch attempts to provide enough alternatives
1400 to effectively use __index__.
1401
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001402- Bug #1536021: __hash__ may now return long int; the final hash
1403 value is obtained by invoking hash on the long int.
1404
Thomas Hellerab1049c2006-08-08 17:37:00 +00001405- Bug #1536786: buffer comparison could emit a RuntimeWarning.

1408 sys.stdin is closed.
1409
Thomas Heller74d36f02006-08-04 18:17:40 +00001410- On Windows, the PyErr_Warn function is now exported from
1411 the Python dll again.
1412
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001413- Bug #1191458: tracing over for loops now produces a line event
1414 on each iteration. Fixing this problem required changing the .pyc
1415 magic number. This means that .pyc files generated before 2.5c1
1416 will be regenerated.
1417
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001418- Bug #1333982: string/number constants were inappropriately stored
1419 in the byte code and co_consts even if they were not used, ie
1420 immediately popped off the stack.
1421
Georg Brandle9462c72006-08-04 18:03:37 +00001422- Fixed a reference-counting problem in property().

1429 generated for generator expressions.
1430
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001431- The distutils version has been changed to 2.5.0. The change to
1432 keep it programmatically in sync with the Python version running
1433 the code (introduced in 2.5b3) has been reverted. It will continue
1434 to be maintained manually as static string literal.
1435
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001436- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001437 and this cannot be converted to the required C type, an exception is
1438 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001439 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001440
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001441- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001442 an exception.
1443
Tim Peterscbdd3502006-09-05 01:47:53 +00001444- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001445 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001446 workarounds for clocks with low resolution, to stop the code yielding
1447 duplicate UUIDs.
1448
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001449- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1450 before raising SystemExit, allowing IDLE to honor quit() and exit().
1451
Neal Norwitzbf8c1952006-08-15 04:14:57 +00001452- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.

1455 file correctly even on Windows.
1456
Georg Brandl0a7d1bb2006-08-11 07:26:10 +00001457- logging's atexit hook now runs even if the rest of the module has
1458 already been cleaned up.
1459
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001460- Bug #1112549, fix DoS attack on cgi.FieldStorage.

Neal Norwitzff4b63b2006-08-04 04:50:21 +00001462- Bug #1531405, format_exception no longer raises an exception if
1463 str(exception) raised an exception.
1464
Neil Schemenauer06ded092006-08-04 16:20:30 +00001465- Fix a bug in the ``compiler`` package that caused invalid code to be
1466 generated for nested functions.

1477 raises the correct exceptions.
1478
Thomas Heller1ce433e2006-08-14 16:20:04 +00001479- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1480 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1481
Thomas Heller86720042006-08-14 11:17:48 +00001482- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1483 uses the _as_parameter_ attribute when objects are passed to foreign
1484 function calls. The ctypes version number was changed to 1.0.1.
1485
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001486- Bug #1530559, struct.pack raises TypeError where it used to convert.
1487 Passing float arguments to struct.pack when integers are expected
1488 now triggers a DeprecationWarning.

1515 code in OpenSSL.
1516
Thomas Hellerdb7b4432006-08-04 19:49:31 +00001517- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.

1523-----
1524
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001525- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1526
Tim Peters4643c2f2006-08-10 22:45:34 +00001527- Bug #1069160. Internal correctness changes were made to
1528 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1529 the documentation was changed to state that the return value
1530 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001533What's New in Python 2.5 beta 3?
1534================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001535
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001536*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001537
1538Core and builtins
1539-----------------
1540
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001541- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001542 returned a long (see PEP 353).
1543
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001544- Bug #1515471: string.replace() accepts character buffers again.
1545
Neal Norwitz07aadb12006-07-30 06:55:48 +00001546- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1547 This provides the proper warning for struct.pack().
1548 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1549
Neal Norwitz0d62a062006-07-30 06:53:31 +00001550- Patch #1531113: Fix augmented assignment with yield expressions.
1551 Also fix a SystemError when trying to assign to yield expressions.
1552
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001553- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1554 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1555 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1556 excessive filesystem operations during imports.
1557
Tim Petersbc24eee2006-07-27 01:14:53 +00001558- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1559 operations on signed longs that are formally undefined by C.
1560 Unfortunately, at least one compiler now cares about that, so complicated
1561 the code to make that compiler happy again.
1562
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001563- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1564
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001565- Patch #1232023: Stop including current directory in search
1566 path on Windows.
1567
Neal Norwitze1fdb322006-07-21 05:32:28 +00001568- Fix some potential crashes found with failmalloc.
1569
Neal Norwitze7563102006-07-17 01:00:16 +00001570- Fix warnings reported by Klocwork's static analysis tool.
1571
Neal Norwitz84be93b2006-07-16 01:50:38 +00001572- Bug #1512814, Fix incorrect lineno's when code within a function
1573 had more than 255 blank lines.
1574
Georg Brandl9dceedb2006-07-12 15:31:17 +00001575- Patch #1521179: Python now accepts the standard options ``--help`` and
1576 ``--version`` as well as ``/?`` on Windows.
1577
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001578- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001579 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001580 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001581
Tim Peters112aad32006-07-19 00:03:19 +00001582- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001583 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001584 new ``sys._current_frames()`` returns a dictionary with one entry,
1585 mapping the faux "thread id" 0 to the current frame.
1586
Ronald Oussoren3075e162006-07-25 20:28:55 +00001587- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001588
Ronald Oussoren3075e162006-07-25 20:28:55 +00001589
Neal Norwitza1f10902006-07-12 07:28:29 +00001590Library
1591-------
1592
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001593- Correction of patch #1455898: In the mbcs decoder, set final=False
1594 for stream decoder, but final=True for the decode function.
1595
Georg Brandl07fec3a2006-08-01 18:49:24 +00001596- os.urandom no longer masks unrelated exceptions like SystemExit or
1597 KeyboardInterrupt.
1598
Tim Peters4643c2f2006-08-10 22:45:34 +00001599- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001600 shutil.copytree on Windows
1601
Georg Brandle34ac7c2006-07-30 11:07:23 +00001602- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1603 refers to file descriptors, not file objects.
1604
Tim Peterscbdd3502006-09-05 01:47:53 +00001605- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001606 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001607 #1513611, and probably others.
1608
Georg Brandledd9b0d2006-07-29 09:33:26 +00001609- Bug #1441397: The compiler module now recognizes module and function
1610 docstrings correctly as it did in Python 2.4.
1611
Tim Peters6f681472006-07-27 23:44:37 +00001612- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1613 lost that tests are sorted by name before being run. This rarely
1614 matters for well-written tests, but can create baffling symptoms if
1615 side effects from one test to the next affect outcomes. ``DocTestFinder``
1616 has been changed to sort the list of tests it returns.
1617
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001618- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001619 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001620
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001621- Bug #978833: Really close underlying socket in _socketobject.close.
1622
Georg Brandldb232dc2006-08-20 13:15:43 +00001623- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1624 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001625
Georg Brandlcf0c1722006-07-26 07:23:32 +00001626- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1627 to recursive calls and call it with the failing package name.
1628
Martin v. Löwis0b483032006-07-25 09:53:12 +00001629- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1630
Georg Brandlc13c34c2006-07-24 14:09:56 +00001631- Patch #1515343: Fix printing of deprecated string exceptions with a
1632 value in the traceback module.
1633
Greg Ward48fae7a2006-07-23 16:05:51 +00001634- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1635
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001636- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1637
Brett Cannoncaebe222006-07-18 04:41:36 +00001638- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1639 argument tuple. For arguments where zero is illegal, the value is forced to
1640 the minimum value that is correct. This is to support an undocumented but
1641 common way people used to fill in inconsequential information in the time
1642 tuple pre-2.4.
1643
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001644- Patch #1220874: Update the binhex module for Mach-O.
1645
Barry Warsawb110bad2006-07-21 14:51:07 +00001646- The email package has improved RFC 2231 support, specifically for
1647 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1648 (name*0=<blah>) parameter continuations. This may change the types of
1649 values returned from email.message.Message.get_param() and friends.
1650 Specifically in some cases where non-encoded continuations were used,
1651 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1652 will just return the string (since non-encoded continuations don't have
1653 charset and language parts).
1654
1655 Also, whereas % values were decoded in all parameter continuations, they are
1656 now only decoded in encoded parameter parts.
1657
Ronald Oussoren3075e162006-07-25 20:28:55 +00001658- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1659
1660- Bug #1517996: IDLE now longer shows the default Tk menu when a
1661 path browser, class browser or debugger is the frontmost window on MacOS X
1662
Barry Warsaw00decd72006-07-27 23:43:15 +00001663- Patch #1520294: Support for getset and member descriptors in types.py,
1664 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1665 of an object against these built-in types and more importantly, for getting
1666 their docstrings printed in the interactive interpreter's help() function.
1667

1671
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001672- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1673 a socket operation on a socket with a timeout, the exception will be
1674 caught correctly. Previously, the exception was not caught.
1675
Thomas Heller1393d6a2006-07-28 21:43:20 +00001676- Patch #1529514: The _ctypes extension is now compiled on more
1677 openbsd target platforms.
1678
Tim Peters9cab5932006-07-28 00:30:00 +00001679- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1680 a memory leak, affecting pickles and deep copies.
1681
Tim Petersbc24eee2006-07-27 01:14:53 +00001682- Bug #1471938: Fix curses module build problem on Solaris 8; patch by

1686
Thomas Hellerce049a02006-07-14 17:51:14 +00001687- Patch #1521817: Index range checking on ctypes arrays containing
1688 exactly one element enabled again. This allows iterating over these
1689 arrays, without the need to check the array size before.
1690
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001691- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001692 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001693 /dev/null in certain cases; this is now fixed.
1694
Thomas Heller47d7a062006-07-12 08:43:47 +00001695- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1696 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001697
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001698- Because of a misspelled preprocessor symbol, ctypes was always
1699 compiled without thread support; this is now fixed.
1700
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001701- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1702 methods now allow their database parameter to be None as the
1703 sleepycat API allows.
1704
Matt Flemingec926502006-07-28 11:27:27 +00001705- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1706 bluetooth API compared with Linux and FreeBSD.

1709-----
1710
1711- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1712 how long the test file should take to play. Now accepts taking 2.93 secs
1713 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1714
Georg Brandl4793aa32006-07-28 18:31:39 +00001715- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1716 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1717 run via ``regrtest.py``. Now they do.

Ronald Oussoren26cad082006-08-01 21:00:57 +00001724Mac
1725---
1726
1727- PythonLauncher now works correctly when the path to the script contains
1728 characters that are treated specially by the shell (such as quotes).
1729
1730- Bug #1527397: PythonLauncher now launches scripts with the working directory
1731 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001732 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001733 expect.

1741Core and builtins
1742-----------------
1743
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001744- Bug #1441486: The literal representation of -(sys.maxint - 1)
1745 again evaluates to a int object, not a long.
1746
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001747- Bug #1501934: The scope of global variables that are locally assigned
1748 using augmented assignment is now correctly determined.
1749
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001750- Bug #927248: Recursive method-wrapper objects can now safely
1751 be released.
1752
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001753- Bug #1417699: Reject locale-specific decimal point in float()
1754 and atof().
1755
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001756- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1757 omit a default "error" argument for NULL pointer. This allows
1758 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001759
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001760- Bug #1519018: 'as' is now validated properly in import statements.
1761
Neal Norwitz28746ab2006-07-09 22:14:42 +00001762- On 64 bit systems, int literals that use less than 64 bits are
1763 now ints rather than longs.
1764
Neal Norwitzed657552006-07-10 00:04:44 +00001765- Bug #1512814, Fix incorrect lineno's when code at module scope
1766 started after line 256.
1767
Tim Peters32a83612006-07-10 21:08:24 +00001768- New function ``sys._current_frames()`` returns a dict mapping thread
1769 id to topmost thread stack frame. This is for expert use, and is
1770 especially useful for debugging application deadlocks. The functionality
1771 was previously available in Fazal Majid's ``threadframe`` extension
1772 module, but it wasn't possible to do this in a wholly threadsafe way from
1773 an extension.
1774

1782
Tim Peters32a83612006-07-10 21:08:24 +00001783- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001784 environment variable to be set in order to the SDK environment
1785 for finding the compiler, include files, etc.
1786

1788
Nick Coghlan2d792252006-07-06 13:47:18 +00001789- warnings.py now ignores ImportWarning by default
1790
Thomas Woutersadd19112006-07-05 11:03:49 +00001791- string.Template() now correctly handles tuple-values. Previously,
1792 multi-value tuples would raise an exception and single-value tuples would
1793 be treated as the value they contain, instead.
1794
Martin v. Löwisede77f52006-07-03 13:01:35 +00001795- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1796 even if some data are received.
1797
Martin v. Löwis45482392006-07-03 12:28:58 +00001798- Bug #1267547: Put proper recursive setup.py call into the
1799 spec file generated by bdist_rpm.

1802 degrees and radians.
1803
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001804- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001805 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001806
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001807- Bug #1514703: Only setup canvas window in turtle when the canvas
1808 is created.
1809
Martin v. Löwis7596e832006-07-01 15:33:37 +00001810- Bug #1513223: .close() of a _socketobj now releases the underlying

1814 attribute values.
1815
1816- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1817 sgmllib ('[' and ']' were not accepted).
1818
Georg Brandl1be63af2006-06-28 20:23:25 +00001819- Fix a bug in the turtle module's end_fill function.
1820
Brett Cannon53ab5b72006-06-22 16:49:14 +00001821- Bug #1510580: The 'warnings' module improperly required that a Warning
1822 category be either a types.ClassType and a subclass of Warning. The proper
1823 check is just that it is a subclass with Warning as the documentation states.
1824
Georg Brandlad29e632006-06-21 17:45:17 +00001825- The compiler module now correctly compiles the new try-except-finally
1826 statement (bug #1509132).
1827
Neal Norwitz60373cd2006-06-22 06:30:50 +00001828- The wsgiref package is now installed properly on Unix.
1829
Vinay Sajip28e57612006-07-01 10:45:20 +00001830- A bug was fixed in logging.config.fileConfig() which caused a crash on
1831 shutdown when fileConfig() was called multiple times.
1832
Gerhard Häring762fbd32006-07-02 17:48:30 +00001833- The sqlite3 module did cut off data from the SQLite database at the first
1834 null character before sending it to a custom converter. This has been fixed
1835 now.
1836
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001837Extension Modules
1838-----------------
1839
Tim Peters112aad32006-07-19 00:03:19 +00001840- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1841 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1842 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001843
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001844- Assigning None to pointer type fields in ctypes structures possible
1845 overwrote the wrong fields, this is fixed now.
1846
1847- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1848 on non-Windows platforms.
1849
1850- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1851 integer or long, without range checking.
1852
1853- Patch #1517790: It is now possible to use custom objects in the ctypes
1854 foreign function argtypes sequence as long as they provide a from_param
1855 method, no longer is it required that the object is a ctypes type.
1856
1857- The '_ctypes' extension module now works when Python is configured
1858 with the --without-threads option.
1859
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001860- Bug #1513646: os.access on Windows now correctly determines write
1861 access, again.
1862
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001863- Bug #1512695: cPickle.loads could crash if it was interrupted with
1864 a KeyboardInterrupt.
1865
Neal Norwitza12aa882006-07-06 06:45:08 +00001866- Bug #1296433: parsing XML with a non-default encoding and
1867 a CharacterDataHandler could crash the interpreter in pyexpat.
1868
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001869- Patch #1516912: improve Modules support for OpenVMS.
1870
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001871Build
1872-----
1873
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001874- Automate Windows build process for the Win64 SSL module.
1875
Tim Peters32a83612006-07-10 21:08:24 +00001876- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001877 Previously, the slight difference could cause compilation errors of the
1878 'zlib' module on systems with more than one version of zlib.
1879
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001880- The MSI compileall step was fixed to also support a TARGETDIR
1881 with spaces in it.
1882
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001883- Bug #1517388: sqlite3.dll is now installed on Windows independent
1884 of Tcl/Tk.
1885
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001886- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001887 trying to be installed even though it's empty.

Neal Norwitzb15ac312006-06-29 04:10:08 +00001889Tests
1890-----
1891
1892- Call os.waitpid() at the end of tests that spawn child processes in order
1893 to minimize resources (zombies).
1894
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001895Documentation
1896-------------
1897
Nick Coghlan2d792252006-07-06 13:47:18 +00001898- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1899 documentation for the warnings module.
1900
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001901- Patch #1509163: MS Toolkit Compiler no longer available.
1902

Nick Coghlanc649ec52006-05-29 12:43:05 +00001906What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +00001907================================
Anthony Baxter51bcb682006-04-05 14:51:42 +00001908
Anthony Baxterd1136802006-06-19 12:04:15 +00001909*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +00001910
1911Core and builtins
1912-----------------
1913
Georg Brandla56b9152006-06-19 06:35:54 +00001914- Patch #1507676: Error messages returned by invalid abstract object operations
1915 (such as iterating over an integer) have been improved and now include the
1916 type of the offending object to help with debugging.
1917
Brett Cannonea3912b2006-06-13 21:46:41 +00001918- Bug #992017: A classic class that defined a __coerce__() method that returned
1919 its arguments swapped would infinitely recurse and segfault the interpreter.
1920
Neal Norwitz909eb122006-06-12 02:13:21 +00001921- Fix the socket tests so they can be run concurrently.
1922
Neal Norwitzb9845e72006-06-12 02:11:18 +00001923- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001924 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001925
Brett Cannon22565aa2006-06-09 22:31:23 +00001926- Bug #532646: object.__call__() will continue looking for the __call__
1927 attribute on objects until one without one is found. This leads to recursion
1928 when you take a class and set its __call__ attribute to an instance of the
1929 class. Originally fixed for classic classes, but this fix is for new-style.
1930 Removes the infinite_rec_3 crasher.
1931
Georg Brandl24250812006-06-09 18:45:48 +00001932- The string and unicode methods startswith() and endswith() now accept
1933 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1934
Brett Cannonde3b0522006-06-08 17:00:45 +00001935- Buffer objects, at the C level, never used the char buffer
1936 implementation even when the char buffer for the wrapped object was
1937 explicitly requested (originally returned the read or write buffer).
1938 Now a TypeError is raised if the char buffer is not present but is
1939 requested.
1940
Georg Brandlddbaa662006-06-04 21:56:52 +00001941- Patch #1346214: Statements like "if 0: suite" are now again optimized
1942 away like they were in Python 2.4.
1943
Georg Brandlb7c8f542006-05-27 12:30:25 +00001944- Builtin exceptions are now full-blown new-style classes instead of
1945 instances pretending to be classes, which speeds up exception handling
1946 by about 80% in comparison to 2.5a2.
1947
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001948- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1949 Unicode 4.1.
1950
Georg Brandlf4ef1162006-05-26 18:03:31 +00001951- Patch #921466: sys.path_importer_cache is now used to cache valid and
1952 invalid file paths for the built-in import machinery which leads to
1953 fewer open calls on startup.
1954
Tim Peters696cf432006-05-24 21:10:40 +00001955- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1956 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1957 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1958 the number of input digits (it was and remains linear-time for bases
1959 2, 4, 8, 16 and 32).
1960
Tim Petersb713ec22006-05-23 18:45:30 +00001961- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1962 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1963 an integer close to ``sys.maxint``. This was repaired by patch
1964 #1335972, which also gives a nice speedup.
1965
Richard Jonescebbefc2006-05-23 18:28:17 +00001966- Patch #1337051: reduced size of frame objects.
1967
1968- PyErr_NewException now accepts a tuple of base classes as its
1969 "base" parameter.
1970
Richard Jones7c88dcc2006-05-23 10:37:38 +00001971- Patch #876206: function call speedup by retaining allocated frame
1972 objects.
1973
Georg Brandl7b90e162006-05-18 07:01:27 +00001974- Bug #1462152: file() now checks more thoroughly for invalid mode
1975 strings and removes a possible "U" before passing the mode to the
1976 C library function.
1977
Neal Norwitz1004a532006-05-15 07:17:23 +00001978- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1979
Neal Norwitz373f0a72006-05-15 07:04:36 +00001980- Bug #1487966: Fix SystemError with conditional expression in assignment
1981
Martin v. Löwis879768d2006-05-11 13:28:43 +00001982- WindowsError now has two error code attributes: errno, which carries
1983 the error values from errno.h, and winerror, which carries the error
1984 values from winerror.h. Previous versions put the winerror.h values
1985 (from GetLastError()) into the errno attribute.
1986
Martin v. Löwis77736712006-05-04 05:51:03 +00001987- Patch #1475845: Raise IndentationError for unexpected indent.
1988
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001989- Patch #1479181: split open() and file() from being aliases for each other.
1990
Tim Peters44bd9862006-06-01 13:49:23 +00001991- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1992 methods were always silently ignored by dictionaries when comparing keys.
1993 They are now passed through (except when using the C API function
1994 ``PyDict_GetItem()``, whose semantics did not change).
1995
1996- Bug #1456209: In some obscure cases it was possible for a class with a
1997 custom ``__eq__()`` method to confuse dict internals when class instances
1998 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1999 No, you don't have any code that did this ;-)

Trent Mick960a3f82006-06-28 20:30:41 +00002004- Bug #1295808: expat symbols should be namespaced in pyexpat
2005
2006- Patch #1462338: Upgrade pyexpat to expat 2.0.0
2007
Brett Cannon6ee7d012006-06-08 16:23:04 +00002008- Change binascii.hexlify to accept a read-only buffer instead of only a char
2009 buffer and actually follow its documentation.
2010
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00002011- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
2012
Nick Coghlanc649ec52006-05-29 12:43:05 +00002013- Patch #1478788 (modified version): The functional extension module has
2014 been renamed to _functools and a functools Python wrapper module added.
2015 This provides a home for additional function related utilities that are
2016 not specifically about functional programming. See PEP 309.
2017
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00002018- Patch #1493701: performance enhancements for struct module.

Georg Brandl8d3342b2006-05-16 07:38:27 +00002022- Patch #1435422: zlib's compress and decompress objects now have a
2023 copy() method.
2024
Andrew MacIntyre92913322006-06-13 15:04:24 +00002025- Patch #1454481: thread stack size is now tunable at runtime for thread
2026 enabled builds on Windows and systems with Posix threads support.
2027
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002028- On Win32, os.listdir now supports arbitrarily-long Unicode path names
2029 (up to the system limit of 32K characters).
2030
2031- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
2032 As a result, these functions now raise WindowsError instead of OSError.
2033
Tim Peters7a822da2006-05-25 21:50:17 +00002034- ``time.clock()`` on Win64 should use the high-performance Windows
2035 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
2036 Windows platforms).
2037
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002038- Calling Tk_Init twice is refused if the first call failed as that
2039 may deadlock.
2040
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00002041- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
2042 accept it without potentially using an uninitialized pointer.
2043
2044- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
2045 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
2046 patch numbers 1494885 and 1494902]

Gregory P. Smith372b5832006-06-05 18:48:21 +00002048- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
Gregory P. Smithf0547d02006-06-05 17:38:04 +00002049 [pybsddb project SF patch number 1466734]
2050
Gregory P. Smith372b5832006-06-05 18:48:21 +00002051- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
2052 parameter is supplied. [SF pybsddb bug #1477863]
2053
Gregory P. Smith3c228b12006-06-05 23:59:37 +00002054- bsddb: the __len__ method of a DB object has been fixed to return correct
2055 results. It could previously incorrectly return 0 in some cases.
2056 Fixes SF bug 1493322 (pybsddb bug 1184012).
2057
Gregory P. Smithff7d9912006-06-08 05:17:08 +00002058- bsddb: the bsddb.dbtables Modify method now raises the proper error and
2059 aborts the db transaction safely when a modifier callback fails.
2060 Fixes SF python patch/bug #1408584.
2061
Gregory P. Smith506f7b52006-06-15 08:52:32 +00002062- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00002063 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00002064 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
2065 database calls that would previously deadlock. [SF python bug #775414]
2066
Vinay Sajip28e57612006-07-01 10:45:20 +00002067- Patch #1446489: add support for the ZIP64 extensions to zipfile.

2093
Martin v. Löwisd8251432006-06-14 05:21:04 +00002094- Patch #1455898: The MBCS codec now supports the incremental mode for
2095 double-byte encodings.
2096
Tim Peters43898b42006-06-14 04:09:25 +00002097- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
2098 guarantee that adjacent triples in the return list always describe
2099 non-adjacent blocks. Previously, a pair of matching blocks could end
2100 up being described by multiple adjacent triples that formed a partition
2101 of the matching pair.
2102
Greg Ward0e0c9f42006-06-11 16:24:11 +00002103- Bug #1498146: fix optparse to handle Unicode strings in option help,
2104 description, and epilog.
2105

2109 clarify docs.
2110
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00002111- The wsgiref package has been added to the standard library.
2112
Nick Coghlan676725d2006-06-08 13:54:49 +00002113- The functions update_wrapper() and wraps() have been added to the functools
2114 module. These make it easier to copy relevant metadata from the original
2115 function when writing wrapper functions.
2116
Tim Petersd6a9eef2006-06-05 01:48:21 +00002117- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
2118 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00002119
Martin v. Löwis3f767792006-06-04 19:36:28 +00002120- Patch #1359618: Speed up charmap encoder by using a trie structure
2121 for lookup.
2122
Tim Petersd609b1a2006-06-02 23:22:51 +00002123- The functions in the ``pprint`` module now sort dictionaries by key
2124 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
2125 if and only if its display required more than one line, although that
2126 wasn't documented. The new behavior increases predictability; e.g.,
2127 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
2128
Georg Brandlfd9a4b12006-05-29 20:57:01 +00002129- Patch #1497027: try HTTP digest auth before basic auth in urllib2

2138
Georg Brandlb89316f2006-05-17 15:51:16 +00002139- Patch #1180296: Two new functions were added to the locale module:
2140 format_string() to get the effect of "format % items" but locale-aware,
2141 and currency() to format a monetary number with currency sign.
2142
Georg Brandle3a25832006-05-17 14:56:04 +00002143- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
2144 and several features added, such as speed and geometry control.

2148
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002149- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
2150 stdout arguments, making it possible to redirect input and output
2151 for remote debugging.
2152
2153- Patch #1484695: Update the tarfile module to version 0.8. This fixes
2154 a couple of issues, notably handling of long file names using the
2155 GNU LONGNAME extension.
2156
2157- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
2158 new flag when ``name`` is already the name of an option flag.
2159
2160- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
2161 package.
2162
2163- Patch #1472854: make the rlcompleter.Completer class usable on non-
2164 UNIX platforms.

2205-----------------
2206
Thomas Heller1b046642006-04-18 18:51:06 +00002207- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2208 by converting these apis from macros into exported functions again:
2209
2210 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2211 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2212 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
2213 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
2214 PyRun_String Py_CompileString
2215
Martin v. Löwis45294a92006-04-18 06:24:08 +00002216- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2217
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002218- All uses of PyStructSequence_InitType have been changed to initialize
2219 the type objects only once, even if the interpreter is initialized
2220 multiple times.
2221
Neal Norwitz61546162006-04-14 05:20:28 +00002222- Bug #1454485, array.array('u') could crash the interpreter. This was
2223 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2224 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2225
2226- Py_UNICODE is unsigned. It was always documented as unsigned, but
2227 due to a bug had a signed value in previous versions.
2228
Tim Peters3a5e8b12006-04-11 01:44:07 +00002229- Patch #837242: ``id()`` of any Python object always gives a positive
2230 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2231 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002232 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002233 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002234
Tim Peters3a5e8b12006-04-11 01:44:07 +00002235 def __hash__(self):
2236 return id(self) # WRONG
2237
2238 because a hash result must be a (short) Python int but it was always
2239 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002240 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002241 was always usable as a hash value before this patch. That's no longer
2242 necessarily so.
2243
2244- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002245 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002246 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002247 #1454844)
2248
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002249- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2250 involving generators that have paused outside of any ``try`` or ``with``
2251 blocks. (In 2.5a1, a paused generator that was part of a reference
2252 cycle could not be garbage collected, regardless of whether it was
2253 paused in a ``try`` or ``with`` block.)

2267 the cachesize parameter.
2268
2269- Bug #1149413: bsddb.*open() no longer raises an exception when using
2270 a temporary db (file=None) with the 'n' flag to truncate on open.

Peter Astrand7d1d4362006-07-14 14:04:45 +00002281- Bug #1223937: subprocess.CalledProcessError reports the exit status
2282 of the process using the returncode attribute, instead of
2283 abusing errno.
2284
Tim Peters711bf302006-04-25 03:31:36 +00002285- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2286 a doctest to be skipped (the code is not run, and the expected output
2287 or exception is ignored).
2288
Nick Coghlanda2268f2006-04-24 04:37:15 +00002289- Fixed contextlib.nested to cope with exceptions being raised and
2290 caught inside exit handlers.
2291
Greg Wardab05edc2006-04-23 03:47:58 +00002292- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2293 hex, octal, or binary; add ``append_const`` action; keep going if
2294 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2295 added ``epilog`` for better help generation).
2296
Tim Peters21fbd572006-04-21 21:18:10 +00002297- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2298 called from a thread spawned as a side effect of importing a module.
2299
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002300- The pydoc module now supports documenting packages contained in
2301 .zip or .egg files.
2302
2303- The pkgutil module now has several new utility functions, such
2304 as ``walk_packages()`` to support working with packages that are either
2305 in the filesystem or zip files.
2306
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002307- The mailbox module can now modify and delete messages from
2308 mailboxes, in addition to simply reading them. Thanks to Gregory
2309 K. Johnson for writing the code, and to the 2005 Google Summer of
2310 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002311
Tim Petersc7605f22006-04-17 21:12:33 +00002312- The ``__del__`` method of class ``local`` in module ``_threading_local``
2313 returned before accomplishing any of its intended cleanup.
2314
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002315- Patch #790710: Add breakpoint command lists in pdb.
2316

2320
Anthony Baxtere29002c2006-04-12 12:07:31 +00002321- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
2322 Windows. Bug #1469163.
2323
Phillip J. Eby47032112006-04-11 01:07:43 +00002324- The warnings, linecache, inspect, traceback, site, and doctest modules
2325 were updated to work correctly with modules imported from zipfiles or
2326 via other PEP 302 __loader__ objects.
2327

2334
Skip Montanaro262fb922006-04-21 02:31:07 +00002335- The pstats.Stats class accepts an optional stream keyword argument to
2336 direct output to an alternate file-like object.
2337
Anthony Baxter51bcb682006-04-05 14:51:42 +00002338Build
2339-----
2340
Martin v. Löwis4be4e652006-04-17 19:25:49 +00002341- The Makefile now has a reindent target, which runs reindent.py on
2342 the library.
2343
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002344- Patch #1470875: Building Python with MS Free Compiler
2345
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00002346- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002347
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002348- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2349 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002350 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002351 CXX from --with-cxx-main, see description in README.
2352
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002353- Patch #1429775: Link extension modules with the shared libpython.
2354
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002355- Fixed a libffi build problem on MIPS systems.
2356
Tim Peters8931ff12006-05-13 23:28:20 +00002357- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2358 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2359 and "%zu" for unsigned integers of type ``size_t``.
2360
Anthony Baxter51bcb682006-04-05 14:51:42 +00002361Tests
2362-----
2363
Nick Coghlanda2268f2006-04-24 04:37:15 +00002364- test_contextlib now checks contextlib.nested can cope with exceptions
2365 being raised and caught inside exit handlers.
2366
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002367- test_cmd_line now checks operation of the -m and -c command switches
2368
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002369- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2370 it separately and by hand. It also wasn't cleaning up its changes to
2371 the current Decimal context.
2372
Thomas Woutersabd08882006-04-26 15:53:30 +00002373- regrtest.py now has a -M option to run tests that test the new limits of
2374 containers, on 64-bit architectures. Running these tests is only sensible
2375 on 64-bit machines with more than two gigabytes of memory. The argument
2376 passed is the maximum amount of memory for the tests to use.
2377
Marc-André Lemburgd0b8e832006-04-19 15:48:59 +00002378Tools

Anthony Baxter51bcb682006-04-05 14:51:42 +00002384Documentation
2385-------------
2386
Tim Petersb06d28c2006-05-12 01:57:59 +00002387- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2388
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002389- PEP 343: Added Context Types section to the library reference
2390 and attempted to bring other PEP 343 related documentation into
2391 line with the implementation and/or python-dev discussions.
2392
Tim Peters8dc73d22006-04-24 02:03:16 +00002393- Bug #1337990: clarified that ``doctest`` does not support examples
2394 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002397What's New in Python 2.5 alpha 1?
2398=================================
2399
Anthony Baxterebed3f62006-04-03 15:03:44 +00002400*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002401
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002402Core and builtins
2403-----------------
2404
Nick Coghlan43832302006-04-23 17:04:07 +00002405- PEP 338: -m command line switch now delegates to runpy.run_module
2406 allowing it to support modules in packages and zipfiles
2407
Martin v. Löwisc661b882006-04-20 04:54:23 +00002408- On Windows, .DLL is not an accepted file name extension for
2409 extension modules anymore; extensions are only found if they
2410 end in .PYD.
2411
Martin v. Löwisea62d252006-04-03 10:56:49 +00002412- Bug #1421664: sys.stderr.encoding is now set to the same value as
2413 sys.stdout.encoding.
2414
Neal Norwitz92e212f2006-04-03 04:48:37 +00002415- __import__ accepts keyword arguments.
2416
Georg Brandlccadf842006-03-31 18:54:53 +00002417- Patch #1460496: round() now accepts keyword arguments.
2418
Anthony Baxter262c00a2006-03-30 10:53:17 +00002419- Fixed bug #1459029 - unicode reprs were double-escaped.
2420
Hye-Shik Changd478f342006-03-23 12:32:36 +00002421- Patch #1396919: The system scope threads are reenabled on FreeBSD
2422 5.4 and later versions.
2423
Neal Norwitze98ccf62006-03-23 05:39:47 +00002424- Bug #1115379: Compiling a Unicode string with an encoding declaration
2425 now gives a SyntaxError.
2426
Georg Brandlabd1ff82006-03-18 07:59:59 +00002427- Previously, Python code had no easy way to access the contents of a
2428 cell object. Now, a ``cell_contents`` attribute has been added
2429 (closes patch #1170323).
2430
Tim Peterscf79aac2006-03-16 01:14:46 +00002431- Patch #1123430: Python's small-object allocator now returns an arena to
2432 the system ``free()`` when all memory within an arena becomes unused
2433 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2434 freed. Some applications will see a drop in virtual memory size now,
2435 especially long-running applications that, from time to time, temporarily
2436 use a large number of small objects. Note that when Python returns an
2437 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002438 platform C library will in turn return that memory to the operating system.
2439 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002440 appears to be effective at least on Microsoft C and gcc-based systems.
2441 Thanks to Evan Jones for hard work and patience.
2442
Georg Brandl533ff6f2006-03-08 18:09:27 +00002443- Patch #1434038: property() now uses the getter's docstring if there is
2444 no "doc" argument given. This makes it possible to legitimately use
2445 property() as a decorator to produce a read-only property.
2446
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002447- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2448 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2449 of requiring an int or long in slicing and a few other contexts, enabling
2450 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2451
Neal Norwitz995acdf2006-03-07 05:01:00 +00002452- Fixed various bugs reported by Coverity's Prevent tool.
2453
Brett Cannonbf364092006-03-01 04:25:17 +00002454- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2455 new exception base class, BaseException, which has a new message attribute.
2456 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2457 Raising a string exception now raises a DeprecationWarning.
2458
Thomas Woutersfb609f42006-02-28 16:37:25 +00002459- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2460 explicitly relative, using 'from .module import name' to mean 'from the same
2461 package as this module is in. Imports without dots still default to the
2462 old relative-then-absolute, unless 'from __future__ import
2463 absolute_import' is used.
2464
Brett Cannona7446e32006-02-27 23:39:10 +00002465- Properly check if 'warnings' raises an exception (usually when a filter set
2466 to "error" is triggered) when raising a warning for raising string
2467 exceptions.
2468
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002469- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002470 The name was removed from Include/code.h.
2471
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002472- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002473
Guido van Rossum1968ad32006-02-25 22:38:04 +00002474- Patch 1433928:
2475 - The copy module now "copies" function objects (as atomic objects).
2476 - dict.__getitem__ now looks for a __missing__ hook before raising
2477 KeyError.
2478
Tim Peters84ef21c2006-02-28 20:39:06 +00002479- PEP 343: with statement implemented. Needs ``from __future__ import
2480 with_statement``. Use of 'with' as a variable will generate a warning.
2481 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002482 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002483 The following objects have __context__ methods:
2484 - The built-in file type.
2485 - The thread.LockType type.
2486 - The following types defined by the threading module:
2487 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2488 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002489
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002490- Fix the encodings package codec search function to only search
2491 inside its own package. Fixes problem reported in patch #1433198.
2492
2493 Note: Codec packages should implement and register their own
2494 codec search function. PEP 100 has the details.
2495
Tim Peters9ea89d22006-06-04 03:26:02 +00002496- PEP 353: Using ``Py_ssize_t`` as the index type.
2497
2498- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2499 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2500 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2501 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2502 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002503
Neal Norwitzfc76d632006-01-10 06:03:13 +00002504- Patch #1400181, fix unicode string formatting to not use the locale.
2505 This is how string objects work. u'%f' could use , instead of .
2506 for the decimal point. Now both strings and unicode always use periods.
2507
Neal Norwitz671b9e32006-01-09 07:07:12 +00002508- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2509 configure would break checking curses.h.
2510
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002511- Bug #959576: The pwd module is now builtin. This allows Python to be
2512 built on UNIX platforms without $HOME set.
2513
Neal Norwitzc10978f2005-12-19 06:07:16 +00002514- Bug #1072182, fix some potential problems if characters are signed.
2515
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002516- Bug #889500, fix line number on SyntaxWarning for global declarations.
2517
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002518- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2519
Neal Norwitze7214a12005-12-18 05:03:17 +00002520- Support for converting hex strings to floats no longer works.
2521 This was not portable. float('0x3') now raises a ValueError.
2522
Barry Warsaw2a38a862005-12-18 01:27:35 +00002523- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002524 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002525 is now displayed in interactive prompt banner.
2526
Georg Brandlfa166682005-12-17 21:45:17 +00002527- Implementation of PEP 341 - Unification of try/except and try/finally.
2528 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002529 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002530
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002531- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2532 now encodes backslash correctly.
2533
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002534- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2535
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002536- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002537 and long longs.
2538
Neal Norwitz67715f02005-11-09 06:59:35 +00002539- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002540 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002541 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002542
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002543- Replaced most Unicode charmap codecs with new ones using the
2544 new Unicode translate string feature in the builtin charmap
2545 codec; the codecs were created from the mapping tables available
2546 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2547 encodings now include a mapping for the Apple logo)
2548
Tim Peterse3547fd2005-12-16 23:13:57 +00002549- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002550
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002551- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002552
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002553- A new AST parser implementation was completed. The abstract
2554 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002555 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002556
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002557- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002558 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2559
Neal Norwitz708e51a2005-10-03 04:48:15 +00002560- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2561
Neal Norwitz11bd1192005-10-03 00:54:56 +00002562- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2563 Provide a warning when a directory is passed on the command line.
2564
Neal Norwitz40d37812005-10-02 01:48:49 +00002565- Fix segfault with invalid coding.
2566
2567- SF bug #772896: unknown encoding results in MemoryError.
2568
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002569- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002570 supported a __len__() method which evaluated to False when the iterator
2571 was empty.
2572
Guido van Rossum630db602005-09-20 18:49:54 +00002573- On 64-bit platforms, when __len__() returns a value that cannot be
2574 represented as a C int, raise OverflowError.
2575
Skip Montanarof8948ca2005-09-19 03:54:46 +00002576- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002577 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002578
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002579- SF bug #893549: parsing keyword arguments was broken with a few format
2580 codes.
2581
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002582- Changes donated by Elemental Security to make it work on AIX 5.3
2583 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2584 bug #105470: test_pwd fails on 64bit system (Opteron).
2585
Guido van Rossum539c6622005-09-14 17:49:54 +00002586- Changes donated by Elemental Security to make it work on HP-UX 11 on
2587 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2588
Georg Brandl4550b8d2005-08-26 06:43:52 +00002589- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002590 (fixes bug #1119418).
2591
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002592- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2593
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002594- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2595 exceptions that cause a function to exit.
2596
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002597- The implementation of set() and frozenset() was revised to use its
2598 own internal data structure. Memory consumption is reduced by 1/3
2599 and there are modest speed-ups as well. The API is unchanged.
2600
Tim Petersde7990b2005-07-17 23:45:23 +00002601- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2602
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002603- SF bug #1229429: PyObject_CallMethod failed to decrement some
2604 reference counts in some error exit cases.
2605
Tim Petersecc6e6a2005-07-10 22:30:55 +00002606- SF bug #1185883: Python's small-object memory allocator took over
2607 a block managed by the platform C library whenever a realloc specified
2608 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002609 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002610 portable way to copy data from the C-managed block into Python's
2611 small-object space without risking a memory fault. Python's small-object
2612 realloc now leaves such blocks under the control of the platform C
2613 realloc.
2614
Michael W. Hudsonb8963812005-07-05 15:21:58 +00002615- SF bug #1232517: An overflow error was not detected properly when
2616 attempting to convert a large float to an int in os.utime().
2617
Raymond Hettinger3296e692005-06-29 23:29:56 +00002618- SF bug #1224347: hex longs now print with lowercase letters just
2619 like their int counterparts.
2620
Michael W. Hudson188d4362005-06-20 16:52:57 +00002621- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2622 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2623 interpreter states; back out that fix and do a better job (see
2624 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2625 for a longer write-up of the problem).
2626
Michael W. Hudsondf888462005-06-03 14:41:55 +00002627- SF patch #1180995: marshal now uses a binary format by default when
2628 serializing floats.
2629
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002630- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2631 the routines that promise to produce IEEE 754 binary representations
2632 of floats now simply copy bytes around.
2633
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002634- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2635 278.
2636
Brett Cannonc3647ac2005-04-26 03:45:26 +00002637- patch #1109424: int, long, float, complex, and unicode now check for the
2638 proper magic slot for type conversions when subclassed. Previously the
2639 magic slot was ignored during conversion. Semantics now match the way
2640 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002641 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002642 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002643 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002644
Barry Warsawc8d907c2005-04-19 23:43:40 +00002645- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2646 NULL, now raise an AttributeError when attempting to set or delete the
2647 attribute. Previously a TypeError was raised, but this was inconsistent
2648 with the equivalent pure-Python implementation.
2649
Michael W. Hudson774479c2005-04-18 08:46:17 +00002650- It is now safe to call PyGILState_Release() before
2651 PyEval_InitThreads() (note that if there is reason to believe there
2652 are multiple threads around you still must call PyEval_InitThreads()
2653 before using the Python API; this fix is for extension modules that
2654 have no way of knowing if Python is multi-threaded yet).
2655
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002656- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2657 disabled caused a crash.
2658
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002659- Bug #1165306: instancemethod_new allowed the creation of a method
2660 with im_class == im_self == NULL, which caused a crash when called.
2661
Tim Petersecc6e6a2005-07-10 22:30:55 +00002662- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002663 fixes the crash seen in bug #1165761
2664
Raymond Hettinger96229b12005-03-11 06:49:40 +00002665- Added two new builtins, any() and all().
2666
Brett Cannon409d8f22005-03-05 06:47:57 +00002667- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002668 (e.g., ``class C(): pass`` is no longer a syntax error).
2669 Patch #1176012 added support to the 'parser' module and 'compiler' package
2670 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002671
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002672- Patch #1115086: Support PY_LONGLONG in structmember.
2673
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002674- Bug #1155938: new style classes did not check that __init__() was
2675 returning None.
2676
Tim Petersecc6e6a2005-07-10 22:30:55 +00002677- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002678 ('\') with a specific error message.
2679
Martin v. Löwisff232d72005-03-03 09:24:38 +00002680- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2681
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002682- Bug #1124295: the __name__ attribute of file objects was
2683 inadvertently made inaccessible in restricted mode.
2684
Tim Petersecc6e6a2005-07-10 22:30:55 +00002685- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002686 an ferror() call.
2687
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002688- min() and max() now support key= arguments with the same meaning as in
2689 list.sort().
2690
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002691- The peephole optimizer now performs simple constant folding in expressions:
2692 (2+3) --> (5).
2693
Raymond Hettingera422c342005-01-11 03:03:27 +00002694- set and frozenset objects can now be marshalled. SF #1098985.
2695
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002696- Bug #1077106: Poor argument checking could cause memory corruption
2697 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002698
Jeremy Hyltonab630502005-02-04 18:44:06 +00002699- The parser did not complain about future statements in illegal
2700 positions. It once again reports a syntax error if a future
2701 statement occurs after anything other than a doc string.
2702
Neil Schemenauercf52c072005-08-12 17:34:58 +00002703- Change the %s format specifier for str objects so that it returns a
2704 unicode instance if the argument is not an instance of basestring and
2705 calling __str__ on the argument returns a unicode instance.
2706
Tim Petersf4e69282006-02-27 17:15:31 +00002707- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2708 current thread state when the auto-GIL-state machinery knows about
2709 it (since the thread state is being deleted, continuing to remember it
2710 can't help, but can hurt if another thread happens to get created with
2711 the same thread id).
2712
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002713Extension Modules
2714-----------------
2715

Tim Petersc9d78aa2006-03-26 23:27:58 +00002728 lockfile, newdir, ni, packmail, poly, rand, statcache, tb, tzparse,
Neal Norwitz10be10c2006-03-16 06:50:13 +00002729 util, whatsound, whrandom, zmod
2730
2731- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2732
2733- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002734 is deprecated. The undocumented re.engine variable no longer exists.
2735
Hye-Shik Changabb903f2006-03-13 10:20:08 +00002736- Bug #1448490: Fixed a bug that ISO-2022 codecs could not handle
2737 SS2 (single-shift 2) escape sequences correctly.
2738
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002739- The unicodedata module was updated to the 4.1 version of the Unicode
2740 database. The 3.2 version is still available as unicodedata.db_3_2_0
2741 for applications that require this specific version (such as IDNA).
2742
Neal Norwitzb62c4332006-03-04 18:35:47 +00002743- The timing module is no longer built by default. It was deprecated
2744 in PEP 4 in Python 2.0 or earlier.
2745
Guido van Rossum1968ad32006-02-25 22:38:04 +00002746- Patch 1433928: Added a new type, defaultdict, to the collections module.
2747 This uses the new __missing__ hook behavior added to dict (see above).
2748
Georg Brandldbd83392006-02-20 09:42:33 +00002749- Bug #854823: socketmodule now builds on Sun platforms even when
2750 INET_ADDRSTRLEN is not defined.
2751
Georg Brandlf4f44152006-02-18 22:29:33 +00002752- Patch #1393157: os.startfile() now has an optional argument to specify
2753 a "command verb" to invoke on the file.
2754
Neal Norwitz082b2df2006-02-07 07:04:46 +00002755- Bug #876637, prevent stack corruption when socket descriptor

2763 than the system default domain.
2764
Martin v. Löwis14694662006-02-03 12:54:16 +00002765- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2766 are reported, the limit on path name lengths is removed, and stat reports
2767 WindowsError now (instead of OSError).
2768
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002769- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

Michael W. Hudson8137bea2005-07-27 20:24:40 +00002843- Patch #1231069: The fcntl.ioctl function now uses the 'I' code for
2844 the request code argument, which results in more C-like behaviour
2845 for large or negative values.
2846
Tim Petersecc6e6a2005-07-10 22:30:55 +00002847- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

2862
Raymond Hettinger984f9bb2005-03-09 16:38:48 +00002863- operator.itemgetter() and operator.attrgetter() now support retrieving

2886
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00002887- the cPickle module no longer accepts the deprecated None option in the
2888 args tuple returned by __reduce__().
2889
Raymond Hettingerb2594052004-12-05 09:25:51 +00002890- itertools.islice() now accepts None for the start and step arguments.
2891 This allows islice() to work more readily with slices:
2892 islice(s.start, s.stop, s.step)
2893
Skip Montanaro0af3ade2005-01-13 04:12:31 +00002894- datetime.datetime() now has a strptime class method which can be used to

Tim Peters112aad32006-07-19 00:03:19 +00002902
Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002903- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2904 been renamed to have only a single underscore prefix. This was done to
2905 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002906
Nick Coghlan43832302006-04-23 17:04:07 +00002907- PEP 338: new module runpy defines a run_module function to support
2908 executing modules which provide access to source code or a code object
2909 via the PEP 302 import mechanisms.
2910
Anthony Baxter93f5b932006-04-03 08:05:07 +00002911- The email module's parsedate_tz function now sets the daylight savings
2912 flag to -1 (unknown) since it can't tell from the date whether it should

2919 in attribute values.
2920
Anthony Baxterc51ee692006-04-01 00:57:31 +00002921- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002922 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002923 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002924 module will not be built.
2925
Tim Petersc17976e2006-04-01 00:26:53 +00002926- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2927 aren't officially supported here, and trying to use them will probably
2928 raise an exception some day. But dicts have been allowed, and "mostly
2929 worked", so support for them won't go away without warning.
2930
Georg Brandl338ef7d2006-03-31 18:42:16 +00002931- Bug #1445068: getpass.getpass() can now be given an explicit stream
2932 argument to specify where to write the prompt.
2933
Georg Brandl22ec80b2006-03-31 18:25:44 +00002934- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2941
Raymond Hettingerfd3fcf02006-03-24 20:43:29 +00002942- Queue.Queue objects now support .task_done() and .join() methods
2943 to make it easier to monitor when daemon threads have completed
2944 processing all enqueued tasks. Patch #1455676.
2945
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002946- popen2.Popen objects now preserve the command in a .cmd attribute.
2947
Thomas Hellerc61c0492006-03-22 10:09:27 +00002948- Added the ctypes ffi package.
2949
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002950- email 4.0 package now integrated. This is largely the same as the email 3.0
2951 package that was included in Python 2.3, except that PEP 8 module names are
2952 now used (e.g. mail.message instead of email.Message). The MIME classes
2953 have been moved to a subpackage (e.g. email.mime.text instead of
2954 email.MIMEText). The old names are still supported for now. Several
2955 deprecated Message methods have been removed and lots of bugs have been
2956 fixed. More details can be found in the email package documentation.
2957
Walter Dörwald40108c92006-03-27 08:15:44 +00002958- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2959 (a subclass of tuple) that provides incremental decoders and encoders
2960 (a way to use stateful codecs without the stream API). Python functions
2961 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2962 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2963 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002964
Walter Dörwald067db482006-03-15 22:17:27 +00002965- Patch #1359365: Calling next() on a closed StringIO.String object raises
2966 a ValueError instead of a StopIteration now (like file and cString.String do).
2967 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2968 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002969
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002970- A regrtest option -w was added to re-run failed tests in verbose mode.

2982 and helpful context managers nested() and closing().
2983

Tim Peterse3547fd2005-12-16 23:13:57 +00003042 SHA1, 224, 256, 384, and 512. Note that recent developments make the
3043 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
3044 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
3045 Ronald L. Rivest offered this advice for Python:
3046
3047 "The consensus of researchers in this area (at least as
3048 expressed at the NIST Hash Function Workshop 10/31/05),
3049 is that SHA-256 is a good choice for the time being, but
3050 that research should continue, and other alternatives may
3051 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00003052
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00003053- Added a subset of Fredrik Lundh's ElementTree package. Available

Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003126- textwrap now processes text chunks at O(n) speed instead of O(n**2).
Raymond Hettinger8bfa8932005-07-15 06:53:35 +00003127 Patch #1209527 (Contributed by Connelly).
3128
Georg Brandl5c5fe2f2005-07-14 06:40:47 +00003129- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
3130 to W3C name (404 -> 'Not Found'). RFE #1216944.
3131
Georg Brandl9e43acf2005-07-04 17:16:07 +00003132- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
3133 as this can cause problems with apps closing all file descriptors.
3134
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00003135- Bug #839151: Fix an attempt to access sys.argv in the warnings module;
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003136 it can be missing in embedded interpreters
Georg Brandl5284b532005-06-26 22:54:58 +00003137
Georg Brandl2f210b62005-06-26 22:09:06 +00003138- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
3139
Georg Brandlfbff1bc2005-06-26 21:36:25 +00003140- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
3141 error messages.
3142
Georg Brandl379f99d2005-06-26 21:09:38 +00003143- Bug #1108948: Cookie.py produced invalid JavaScript code.
3144
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00003145- The tokenize module now detects and reports indentation errors.
3146 Bug #1224621.
3147
Raymond Hettinger68c04532005-06-10 11:05:19 +00003148- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00003149 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00003150 the generate_tokens() function now accepts a callable argument that
3151 terminates by raising StopIteration.
3152
Georg Brandl9166e1a2005-06-04 09:20:03 +00003153- Bug #1196315: fix weakref.WeakValueDictionary constructor.
3154
Georg Brandl268e61c2005-06-03 14:28:50 +00003155- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
3156 component of the path.
3157
Skip Montanaro174dd222005-05-14 20:54:16 +00003158- Patch #1120353: The xmlrpclib module provides better, more transparent,
3159 support for datetime.{datetime,date,time} objects. With use_datetime set
3160 to True, applications shouldn't have to fiddle with the DateTime wrapper
3161 class at all.
3162
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00003163- distutils.commands.upload was added to support uploading distribution
3164 files to PyPI.
3165
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00003166- distutils.commands.register now encodes the data as UTF-8 before posting
3167 them to PyPI.
3168
Raymond Hettinger267b8682005-03-27 10:47:39 +00003169- decimal operator and comparison methods now return NotImplemented
3170 instead of raising a TypeError when interacting with other types. This
3171 allows other classes to implement __radd__ style methods and have them
3172 work as expected.
3173
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00003174- Bug #1163325: Decimal infinities failed to hash. Attempting to
3175 hash a NaN raised an InvalidOperation instead of a TypeError.
3176
Tim Petersecc6e6a2005-07-10 22:30:55 +00003177- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00003178 stream compression; add, for symmetry reasons, r:* as a synonym of r.
3179

3211
Guido van Rossumd0641422005-02-03 15:01:24 +00003212- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
3213 disables recursive traversal through instance attributes, which can
3214 be exploited in various ways.
3215
Tim Peterse3547fd2005-12-16 23:13:57 +00003216- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00003217 flags on the HTTP listening socket.
3218
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00003219- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
3220 Fixed by reading the HTTP body in chunks instead of one big socket.read().
3221
Fred Drakefbdeaad2006-07-29 16:56:15 +00003222- Patches #893642, #1039083: add allow_none, encoding arguments to
3223 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00003224
Martin v. Löwis1d11de62005-01-29 13:29:23 +00003225- Bug #1110478: Revert os.environ.update to do putenv again.
3226
Thomas Hellerd6c6e222005-01-20 19:20:16 +00003227- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
3228
Martin v. Löwis22b457e2005-01-16 08:40:58 +00003229- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
3230
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003231- Enhancements to the csv module:
3232
3233 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003234 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003235 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003236 + Dialect parameter parsing has been re-implemented to improve error
3237 reporting.
3238 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3239 dictates.
3240 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003241 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003242 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003243 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3244 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003245 + reader now allows \r characters to be quoted (previously it only allowed
3246 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003247 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003248 + Dialect classes passed to the module are no longer instantiated by
3249 the module before being parsed (the former validation scheme required
3250 this, but the mechanism was unreliable).
3251 + The dialect registry now contains instances of the internal
3252 C-coded dialect type, rather than references to python objects.
3253 + the internal c-coded dialect type is now immutable.
3254 + register_dialect now accepts the same keyword dialect specifications
3255 as the reader and writer, allowing the user to register dialects
3256 without first creating a dialect class.
3257 + a configurable limit to the size of parsed fields has been added -
3258 previously, an unmatched quote character could result in the entire
3259 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003260 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003261 the parser field size limit (returning the former limit). The initial
3262 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003263 + A line_num attribute has been added to the reader object, which tracks
3264 the number of lines read from the source iterator. This is not
3265 the same as the number of records returned, as records can span
3266 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003267 + reader and writer objects were not being registered with the cyclic-GC.
3268 This has been fixed.
3269
Brett Cannone6539c42005-01-08 02:43:53 +00003270- _DummyThread objects in the threading module now delete self.__block that is
3271 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3272 lock primitives tend to be limited in number and thus should not be wasted on
3273 a _DummyThread object. Fixes bug #1089632.
3274
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003275- The imghdr module now detects Exif files.
3276
Raymond Hettinger6065d322004-12-20 23:51:53 +00003277- StringIO.truncate() now correctly adjusts the size attribute.
3278 (Bug #951915).
3279
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003280- locale.py now uses an updated locale alias table (built using
3281 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3282 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003283 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003284
Raymond Hettinger3557f422004-12-07 12:02:02 +00003285- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3286
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003287- the pickle module no longer accepts the deprecated None option in the
3288 args tuple returned by __reduce__().
3289
Brett Cannon84667c02004-12-07 03:25:18 +00003290- optparse now optionally imports gettext. This allows its use in setup.py.
3291
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003292- the pickle module no longer uses the deprecated bin parameter.
3293
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003294- the shelve module no longer uses the deprecated binary parameter.
3295
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003296- the pstats module no longer uses the deprecated ignore() method.
3297
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003298- the filecmp module no longer uses the deprecated use_statcache argument.
3299
Raymond Hettinger664347b2004-12-04 21:21:53 +00003300- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3301 extended or overridden by subclasses. Formerly, the subclassed method would
3302 be ignored by the rest of the module. (Bug #1078905).
3303
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003304- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003305 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003306
Walter Dörwald36733692004-12-22 12:50:50 +00003307- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3308 once when a size argument is given. This prevents a buffer overflow in the
3309 tokenizer with very long source lines.
3310
Barry Warsaw538561e2006-01-01 21:48:54 +00003311- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3312 immediately after creating the object, without any intervening
3313 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003314
Skip Montanaro05885812005-01-16 20:48:27 +00003315- The reconvert.quote function can now emit triple-quoted strings. The
3316 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003317
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003318- ``UserString.MutableString`` now supports negative indices in
3319 ``__setitem__`` and ``__delitem__``
3320
Greg Ward40407942005-03-05 02:53:17 +00003321- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3322 correctly.
3323
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003324- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3325 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3326 character even if the user has passed a size parameter to get a proper
3327 line ending. Remove the special handling of a "\r\n" that has been split
3328 between two lines.
3329
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003330- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3331 about illegal code points. The codec now supports PEP 293 style error
3332 handlers.
3333
Walter Dörwald78a78b02005-09-01 12:04:29 +00003334- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003335 from the input stream, so that the output is a byte string in the correct
3336 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003337
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003338- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3339 considering it exactly like a '*'.
3340
Walter Dörwald007f8df2005-10-09 19:42:27 +00003341- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3342 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003343
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003344- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3345
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003346- Patch #1413711: Certain patterns of differences were making difflib
3347 touch the recursion limit.
3348
Walter Dörwald58917a62006-03-31 15:26:22 +00003349- Bug #947906: An object oriented interface has been added to the calendar
3350 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003351 called as a script (e.g. via ``python -mcalendar``). Localized month and
3352 weekday names can be ouput (even if an exotic encoding is used) using
3353 special classes that use unicode.

3378 vulnerability in zlib 1.2.1 and 1.2.2.
3379
Brett Cannon08cd5982005-04-24 22:26:38 +00003380- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3381 flags that change binary compatibility. Changes were also made to
3382 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003383 compilation of the interpreter and of C extensions through distutils.

Bob Ippolitoed233462005-03-29 13:47:59 +00003385- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3386 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3387 no longer exists). This configure patch makes things right.
3388
Martin v. Löwise2713be2005-03-08 15:03:08 +00003389- Bug #1158607: Build with --disable-unicode again.
3390
Brett Cannon46d96232005-02-16 00:07:19 +00003391- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3392 defined. Discovered as a result of not being able to build on OS X.
3393
Brett Cannon516592f2004-12-07 00:42:59 +00003394- setup.py now uses the directories specified in LDFLAGS using the -L option
3395 and in CPPFLAGS using the -I option for adding library and include
3396 directories, respectively, for compiling extension modules against. This has
3397 led to the core being compiled using the values in CPPFLAGS. It also removes
3398 the need for the special-casing of both DarwinPorts and Fink for darwin since
3399 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3400 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3401 Fink, ``-I/opt/local/include`` for DarwinPorts).
3402
Brett Cannon43802422005-02-10 20:48:03 +00003403- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3404 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3405 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3406 Closes bug #1096244. Thanks Gregory Bond.

3409-----
3410
Tim Petersc9d78aa2006-03-26 23:27:58 +00003411- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3412 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3413 is obtained via the ``PyObject_`` family, it must be released via the
3414 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3415 always been officially true, but when Python's small-object allocator was
3416 introduced, an attempt was made to cater to a few extension modules
3417 discovered at the time that obtained memory via ``PyObject_New`` but
3418 released it via ``PyMem_DEL``. It's years later, and if such code still
3419 exists it will fail now (probably with segfaults, but calling wrong
3420 low-level memory management functions can yield many symptoms).
3421
Raymond Hettingerbeb31012005-08-16 03:47:52 +00003422- Added a C API for set and frozenset objects.
3423
Raymond Hettinger66517482004-12-03 11:45:13 +00003424- Removed PyRange_New().
3425
Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003426- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3427 mapping argument now. This string is used as a mapping table. Byte values
3428 greater than the length of the string and 0xFFFE are treated as undefined
3429 mappings.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003436
Hye-Shik Changaaa2f1d2005-12-10 17:44:27 +00003437- Patch #1276356: New resource "urlfetch" is implemented. This enables
3438 even impatient people to run tests that require remote files.
