161
Guido van Rossumaa975432008-04-10 22:43:58 +0000162- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
163 having a self-referential tuple, which is possible from C code. Nor did
164 object's tp_str consider that a type's tp_str could do something that could
165 lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
166 respectively, fixed the issues. (Backport of r58288 from trunk.)

172 reference on the outer class name.
173
Amaury Forgeot d'Arca79e0502008-03-24 21:16:28 +0000174- Issue #1477: With narrow Unicode builds, the unicode escape sequence
175 \Uxxxxxxxx did not accept values outside the Basic Multilingual Plane. This
176 affected raw unicode literals and the 'raw-unicode-escape' codec. Now
177 UTF-16 surrogates are generated in this case, like normal unicode literals
178 and the 'unicode-escape' codec.
179
Neal Norwitzb3635f92008-03-18 04:17:36 +0000180- Issue #2321: use pymalloc for unicode object string data to reduce
181 memory usage in some circumstances.

187 parameter but was not verifying that it was greater than zero. Values
188 less than zero will now raise a SystemError and return NULL to indicate a
189 bug in the calling C code.
190
Gregory P. Smith9aa040d2008-06-02 00:07:25 +0000191- Issue #2588, #2589: Fix potential integer underflow and overflow
192 conditions in the PyOS_vsnprintf C API function.
193
Gregory P. Smithcae7f882008-09-07 06:44:12 +0000194- Issue #1204: The configure script now tests for additional libraries
195 that may be required when linking against readline. This fixes issues
196 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

1225-----------------
1226
Neal Norwitz0bcafac2006-09-11 08:51:17 +00001227- Make _PyGILState_NoteThreadState() static, it was not used anywhere
1228 outside of pystate.c and should not be necessary.
1229
Brett Cannon19d76c52006-09-09 07:18:44 +00001230- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
1231 allows calling unicode() on exceptions classes directly to succeed.
1232
Georg Brandlecab6232006-09-06 06:47:02 +00001233- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
1234 Also make sure that every exception class has __module__ set to
1235 'exceptions'.
1236
Georg Brandl37a9e572006-09-06 06:09:34 +00001237- Bug #1550983: emit better error messages for erroneous relative

Neal Norwitz29a5fdb2006-09-05 02:21:38 +00001248- The return tuple from str.rpartition(sep) is (tail, sep, head) where
1249 head is the original string if sep was not found.
1250
Neal Norwitz3b3aae02006-09-05 03:56:01 +00001251- Bug #1520864: unpacking singleton tuples in list comprehensions and
1252 generator expressions (x for x, in ... ) works again. Fixing this problem
1253 required changing the .pyc magic number. This means that .pyc files
1254 generated before 2.5c2 will be regenerated.

Neal Norwitz24b6f202006-09-05 04:43:56 +00001369- Fix infinite recursion when subclassing long and overriding __hash__.
1370
1371- Fix concatenation (+=) of long strings.
1372
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001373- Unicode objects will no longer raise an exception when being
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001374 compared equal or unequal to a string and a UnicodeDecodeError
1375 exception occurs, e.g. as result of a decoding failure.
Neal Norwitz56423e52006-08-13 18:11:08 +00001376
Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001377 Instead, the equal (==) and unequal (!=) comparison operators will
1378 now issue a UnicodeWarning and interpret the two objects as
1379 unequal. The UnicodeWarning can be filtered as desired using
1380 the warning framework, e.g. silenced completely, turned into an
1381 exception, logged, etc.
1382
1383 Note that compare operators other than equal and unequal will still
1384 raise UnicodeDecodeError exceptions as they've always done.
Neal Norwitz8a87f5d2006-08-12 17:03:09 +00001385
Marc-André Lemburg757ea272006-08-14 11:44:34 +00001386- Fix segfault when doing string formatting on subclasses of long.
1387
1388- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines
1389 with new-style classes.
1390
1391- Fix bug related to __len__ functions returning negative values with
1392 classic classes.
1393
1394- Patch #1538606, Fix __index__() clipping. There were some problems
1395 discovered with the API and how integers that didn't fit into Py_ssize_t
1396 were handled. This patch attempts to provide enough alternatives
1397 to effectively use __index__.
1398
Martin v. Löwisab2f8f72006-08-09 07:57:39 +00001399- Bug #1536021: __hash__ may now return long int; the final hash
1400 value is obtained by invoking hash on the long int.
1401
Thomas Hellerab1049c2006-08-08 17:37:00 +00001402- Bug #1536786: buffer comparison could emit a RuntimeWarning.

1405 sys.stdin is closed.
1406
Thomas Heller74d36f02006-08-04 18:17:40 +00001407- On Windows, the PyErr_Warn function is now exported from
1408 the Python dll again.
1409
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001410- Bug #1191458: tracing over for loops now produces a line event
1411 on each iteration. Fixing this problem required changing the .pyc
1412 magic number. This means that .pyc files generated before 2.5c1
1413 will be regenerated.
1414
Neal Norwitz0cbd8052006-08-04 05:09:28 +00001415- Bug #1333982: string/number constants were inappropriately stored
1416 in the byte code and co_consts even if they were not used, ie
1417 immediately popped off the stack.
1418
Georg Brandle9462c72006-08-04 18:03:37 +00001419- Fixed a reference-counting problem in property().

1424
Neil Schemenauer4c6b0d52006-08-16 23:38:05 +00001425- Fix a bug in the ``compiler`` package that caused invalid code to be
1426 generated for generator expressions.
1427
Marc-André Lemburg574cfea2006-08-16 16:11:01 +00001428- The distutils version has been changed to 2.5.0. The change to
1429 keep it programmatically in sync with the Python version running
1430 the code (introduced in 2.5b3) has been reverted. It will continue
1431 to be maintained manually as static string literal.
1432
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001433- If the Python part of a ctypes callback function returns None,
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001434 and this cannot be converted to the required C type, an exception is
1435 printed with PyErr_WriteUnraisable. Before this change, the C
Andrew M. Kuchlingc13324e2006-08-16 17:11:18 +00001436 callback returned arbitrary values to the calling code.
Thomas Hellerb4a0cf12006-08-16 15:10:12 +00001437
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001438- The __repr__ method of a NULL ctypes.py_object() no longer raises
Thomas Hellerb0aa98f2006-08-16 14:07:44 +00001439 an exception.
1440
Tim Peterscbdd3502006-09-05 01:47:53 +00001441- uuid.UUID now has a bytes_le attribute. This returns the UUID in
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001442 little-endian byte order for Windows. In addition, uuid.py gained some
Anthony Baxter58179592006-08-16 13:08:25 +00001443 workarounds for clocks with low resolution, to stop the code yielding
1444 duplicate UUIDs.
1445
Kurt B. Kaiserd112bc72006-08-16 05:01:42 +00001446- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
1447 before raising SystemExit, allowing IDLE to honor quit() and exit().

1460 str(exception) raised an exception.
1461
Neil Schemenauer06ded092006-08-04 16:20:30 +00001462- Fix a bug in the ``compiler`` package that caused invalid code to be

1475
Thomas Heller1ce433e2006-08-14 16:20:04 +00001476- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
1477 '-no-stack-protector' compiler flag for OpenBSD has been removed.
1478
Thomas Heller86720042006-08-14 11:17:48 +00001479- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
1480 uses the _as_parameter_ attribute when objects are passed to foreign
1481 function calls. The ctypes version number was changed to 1.0.1.
1482
Bob Ippolitoe6c9f982006-08-04 23:59:21 +00001483- Bug #1530559, struct.pack raises TypeError where it used to convert.

Marc-André Lemburg040f76b2006-08-14 10:55:19 +00001522- New API for Unicode rich comparisons: PyUnicode_RichCompare()
1523
Tim Peters4643c2f2006-08-10 22:45:34 +00001524- Bug #1069160. Internal correctness changes were made to
1525 ``PyThreadState_SetAsyncExc()``. A test case was added, and
1526 the documentation was changed to state that the return value
1527 is always 1 (normal) or 0 (if the specified thread wasn't found).

Fred Drake53912162006-07-29 13:22:49 +00001530What's New in Python 2.5 beta 3?
1531================================
Neal Norwitza1f10902006-07-12 07:28:29 +00001532
Anthony Baxter5d32a9f2006-08-02 07:43:09 +00001533*Release date: 03-AUG-2006*
Neal Norwitza1f10902006-07-12 07:28:29 +00001534
1535Core and builtins
1536-----------------
1537
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001538- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
Neal Norwitzc5e060d2006-08-02 06:14:22 +00001539 returned a long (see PEP 353).
1540
Neal Norwitzf71ec5a2006-07-30 06:57:04 +00001541- Bug #1515471: string.replace() accepts character buffers again.
1542
Neal Norwitz07aadb12006-07-30 06:55:48 +00001543- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
1544 This provides the proper warning for struct.pack().
1545 PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
1546
Neal Norwitz0d62a062006-07-30 06:53:31 +00001547- Patch #1531113: Fix augmented assignment with yield expressions.
1548 Also fix a SystemError when trying to assign to yield expressions.
1549
Phillip J. Ebyf7575d02006-07-28 21:12:07 +00001550- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
1551 with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
1552 used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
1553 excessive filesystem operations during imports.
1554
Tim Petersbc24eee2006-07-27 01:14:53 +00001555- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
1556 operations on signed longs that are formally undefined by C.
1557 Unfortunately, at least one compiler now cares about that, so complicated
1558 the code to make that compiler happy again.
1559
Martin v. Löwis982e9fe2006-07-24 12:54:17 +00001560- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
1561
Martin v. Löwisd22968a2006-07-24 11:54:53 +00001562- Patch #1232023: Stop including current directory in search
1563 path on Windows.
1564
Neal Norwitze1fdb322006-07-21 05:32:28 +00001565- Fix some potential crashes found with failmalloc.
1566
Neal Norwitze7563102006-07-17 01:00:16 +00001567- Fix warnings reported by Klocwork's static analysis tool.
1568
Neal Norwitz84be93b2006-07-16 01:50:38 +00001569- Bug #1512814, Fix incorrect lineno's when code within a function
1570 had more than 255 blank lines.
1571
Georg Brandl9dceedb2006-07-12 15:31:17 +00001572- Patch #1521179: Python now accepts the standard options ``--help`` and
1573 ``--version`` as well as ``/?`` on Windows.
1574
Andrew M. Kuchling93c928e2006-07-26 17:19:39 +00001575- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
Neal Norwitza1f10902006-07-12 07:28:29 +00001576 again. Fixing this problem required changing the .pyc magic number.
Neal Norwitz4ffedad2006-08-04 04:58:47 +00001577 This means that .pyc files generated before 2.5b3 will be regenerated.
Neal Norwitza1f10902006-07-12 07:28:29 +00001578
Tim Peters112aad32006-07-19 00:03:19 +00001579- Bug #1524317: Compiling Python ``--without-threads`` failed.
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001580 The Python core compiles again, and, in a build without threads, the
Tim Peters112aad32006-07-19 00:03:19 +00001581 new ``sys._current_frames()`` returns a dictionary with one entry,
1582 mapping the faux "thread id" 0 to the current frame.
1583
Ronald Oussoren3075e162006-07-25 20:28:55 +00001584- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
Tim Petersbc24eee2006-07-27 01:14:53 +00001585

Neal Norwitza1f10902006-07-12 07:28:29 +00001587Library
1588-------
1589
Martin v. Löwis961b91b2006-08-02 13:53:55 +00001590- Correction of patch #1455898: In the mbcs decoder, set final=False
1591 for stream decoder, but final=True for the decode function.
1592
Georg Brandl07fec3a2006-08-01 18:49:24 +00001593- os.urandom no longer masks unrelated exceptions like SystemExit or
1594 KeyboardInterrupt.
1595
Tim Peters4643c2f2006-08-10 22:45:34 +00001596- Bug #1525866: Don't copy directory stat times in
Martin v. Löwis4e678382006-07-30 13:00:31 +00001597 shutil.copytree on Windows
1598
Georg Brandle34ac7c2006-07-30 11:07:23 +00001599- Bug #1002398: The documentation for os.path.sameopenfile now correctly
1600 refers to file descriptors, not file objects.
1601
Tim Peterscbdd3502006-09-05 01:47:53 +00001602- The renaming of the xml package to xmlcore, and the import hackery done
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001603 to make it appear at both names, has been removed. Bug #1511497,
Fred Drakefbdeaad2006-07-29 16:56:15 +00001604 #1513611, and probably others.
1605
Georg Brandledd9b0d2006-07-29 09:33:26 +00001606- Bug #1441397: The compiler module now recognizes module and function
1607 docstrings correctly as it did in Python 2.4.
1608
Tim Peters6f681472006-07-27 23:44:37 +00001609- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
1610 lost that tests are sorted by name before being run. This rarely
1611 matters for well-written tests, but can create baffling symptoms if
1612 side effects from one test to the next affect outcomes. ``DocTestFinder``
1613 has been changed to sort the list of tests it returns.
1614
Andrew M. Kuchlingf9b5b8e2006-08-16 14:21:14 +00001615- The distutils version has been changed to 2.5.0, and is now kept
Martin v. Löwis1f30c372006-07-30 13:14:05 +00001616 in sync with sys.version_info[:3].
Martin v. Löwis997ceff2006-07-27 06:38:16 +00001617
Martin v. Löwis9298eff2006-07-26 12:12:56 +00001618- Bug #978833: Really close underlying socket in _socketobject.close.
1619
Georg Brandldb232dc2006-08-20 13:15:43 +00001620- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
1621 title().
Georg Brandl0619a322006-07-26 07:40:17 +00001622
Georg Brandlcf0c1722006-07-26 07:23:32 +00001623- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
1624 to recursive calls and call it with the failing package name.
1625
Martin v. Löwis0b483032006-07-25 09:53:12 +00001626- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
1627
Georg Brandlc13c34c2006-07-24 14:09:56 +00001628- Patch #1515343: Fix printing of deprecated string exceptions with a
1629 value in the traceback module.
1630
Greg Ward48fae7a2006-07-23 16:05:51 +00001631- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
1632
Martin v. Löwis426f4a12006-07-18 17:46:31 +00001633- Patch #1524429: Use repr() instead of backticks in Tkinter again.
1634
Brett Cannoncaebe222006-07-18 04:41:36 +00001635- Bug #1520914: Change time.strftime() to accept a zero for any position in its
1636 argument tuple. For arguments where zero is illegal, the value is forced to
1637 the minimum value that is correct. This is to support an undocumented but
1638 common way people used to fill in inconsequential information in the time
1639 tuple pre-2.4.
1640
Bob Ippolito5ea4bf12006-07-15 16:53:15 +00001641- Patch #1220874: Update the binhex module for Mach-O.
1642
Barry Warsawb110bad2006-07-21 14:51:07 +00001643- The email package has improved RFC 2231 support, specifically for
1644 recognizing the difference between encoded (name*0*=<blah>) and non-encoded
1645 (name*0=<blah>) parameter continuations. This may change the types of
1646 values returned from email.message.Message.get_param() and friends.
1647 Specifically in some cases where non-encoded continuations were used,
1648 get_param() used to return a 3-tuple of (None, None, string) whereas now it
1649 will just return the string (since non-encoded continuations don't have
1650 charset and language parts).
1651
1652 Also, whereas % values were decoded in all parameter continuations, they are
1653 now only decoded in encoded parameter parts.
1654
Ronald Oussoren3075e162006-07-25 20:28:55 +00001655- Bug #1517990: IDLE keybindings on MacOS X now work correctly
1656
1657- Bug #1517996: IDLE now longer shows the default Tk menu when a
1658 path browser, class browser or debugger is the frontmost window on MacOS X
1659
Barry Warsaw00decd72006-07-27 23:43:15 +00001660- Patch #1520294: Support for getset and member descriptors in types.py,
1661 inspect.py, and pydoc.py. Specifically, this allows for querying the type
1662 of an object against these built-in types and more importantly, for getting
1663 their docstrings printed in the interactive interpreter's help() function.

1667-----------------
1668
Neal Norwitz9b0ca792006-08-02 06:46:21 +00001669- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
1670 a socket operation on a socket with a timeout, the exception will be
1671 caught correctly. Previously, the exception was not caught.
1672
Thomas Heller1393d6a2006-07-28 21:43:20 +00001673- Patch #1529514: The _ctypes extension is now compiled on more
1674 openbsd target platforms.
1675
Tim Peters9cab5932006-07-28 00:30:00 +00001676- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
1677 a memory leak, affecting pickles and deep copies.
1678
Tim Petersbc24eee2006-07-27 01:14:53 +00001679- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
Andrew M. Kuchling10c2b552006-07-26 17:22:21 +00001680 Paul Eggert.
1681
Martin v. Löwisbda0dde2006-07-24 10:26:33 +00001682- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
1683
Thomas Hellerce049a02006-07-14 17:51:14 +00001684- Patch #1521817: Index range checking on ctypes arrays containing
1685 exactly one element enabled again. This allows iterating over these
1686 arrays, without the need to check the array size before.
1687
Thomas Heller6e1ad2e2006-07-13 17:05:13 +00001688- Bug #1521375: When the code in ctypes.util.find_library was
Andrew M. Kuchlingb7eca832006-07-13 17:37:26 +00001689 run with root privileges, it could overwrite or delete
Thomas Heller2bdf29e2006-07-13 17:01:14 +00001690 /dev/null in certain cases; this is now fixed.
1691
Thomas Heller47d7a062006-07-12 08:43:47 +00001692- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
1693 default mode for loading shared libraries in ctypes.
Neal Norwitza1f10902006-07-12 07:28:29 +00001694
Thomas Hellerb4dc2ef2006-07-13 09:53:47 +00001695- Because of a misspelled preprocessor symbol, ctypes was always
1696 compiled without thread support; this is now fixed.
1697
Gregory P. Smith641cddf2006-07-28 01:35:25 +00001698- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
1699 methods now allow their database parameter to be None as the
1700 sleepycat API allows.
1701
Matt Flemingec926502006-07-28 11:27:27 +00001702- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
1703 bluetooth API compared with Linux and FreeBSD.

1707
1708- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
1709 how long the test file should take to play. Now accepts taking 2.93 secs
1710 (exact time) +/- 10% instead of the hard-coded 3.1 sec.
1711
Georg Brandl4793aa32006-07-28 18:31:39 +00001712- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
1713 ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
1714 run via ``regrtest.py``. Now they do.

1723
1724- PythonLauncher now works correctly when the path to the script contains
1725 characters that are treated specially by the shell (such as quotes).
1726
1727- Bug #1527397: PythonLauncher now launches scripts with the working directory
1728 set to the directory that contains the script instead of the user home
Tim Peters4643c2f2006-08-10 22:45:34 +00001729 directory. That latter was an implementation accident and not what users
Ronald Oussoren26cad082006-08-01 21:00:57 +00001730 expect.

1738Core and builtins
1739-----------------
1740
Neil Schemenauer6ec6ab02006-07-09 21:19:29 +00001741- Bug #1441486: The literal representation of -(sys.maxint - 1)
1742 again evaluates to a int object, not a long.
1743
Neil Schemenauer0e07b602006-07-09 16:16:34 +00001744- Bug #1501934: The scope of global variables that are locally assigned
1745 using augmented assignment is now correctly determined.
1746
Martin v. Löwisd5cfa542006-07-03 13:47:40 +00001747- Bug #927248: Recursive method-wrapper objects can now safely
1748 be released.
1749
Martin v. Löwisfcfff0a2006-07-03 12:19:50 +00001750- Bug #1417699: Reject locale-specific decimal point in float()
1751 and atof().
1752
Hye-Shik Change6a1cb92006-06-23 21:16:18 +00001753- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
1754 omit a default "error" argument for NULL pointer. This allows
1755 the parser to take a codec from cjkcodecs again.
Georg Brandlad29e632006-06-21 17:45:17 +00001756
Neal Norwitzfb48afa2006-07-08 05:31:37 +00001757- Bug #1519018: 'as' is now validated properly in import statements.
1758
Neal Norwitz28746ab2006-07-09 22:14:42 +00001759- On 64 bit systems, int literals that use less than 64 bits are
1760 now ints rather than longs.
1761
Neal Norwitzed657552006-07-10 00:04:44 +00001762- Bug #1512814, Fix incorrect lineno's when code at module scope
1763 started after line 256.
1764
Tim Peters32a83612006-07-10 21:08:24 +00001765- New function ``sys._current_frames()`` returns a dict mapping thread
1766 id to topmost thread stack frame. This is for expert use, and is
1767 especially useful for debugging application deadlocks. The functionality
1768 was previously available in Fazal Majid's ``threadframe`` extension
1769 module, but it wasn't possible to do this in a wholly threadsafe way from
1770 an extension.
1771

1773-------
1774
Martin v. Löwis77621582006-07-30 13:27:31 +00001775- Bug #1257728: Mention Cygwin in distutils error message about a missing
1776 VS 2003.
1777
Martin v. Löwis06c68b82006-07-10 22:11:28 +00001778- Patch #1519566: Update turtle demo, make begin_fill idempotent.
1779
Tim Peters32a83612006-07-10 21:08:24 +00001780- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
Martin v. Löwis8d656812006-07-10 07:23:48 +00001781 environment variable to be set in order to the SDK environment
1782 for finding the compiler, include files, etc.
1783
Martin v. Löwis388a8c22006-07-06 19:28:03 +00001784- Bug #1515998: Properly generate logical ids for files in bdist_msi.
1785
Nick Coghlan2d792252006-07-06 13:47:18 +00001786- warnings.py now ignores ImportWarning by default
1787
Thomas Woutersadd19112006-07-05 11:03:49 +00001788- string.Template() now correctly handles tuple-values. Previously,
1789 multi-value tuples would raise an exception and single-value tuples would
1790 be treated as the value they contain, instead.
1791
Martin v. Löwisede77f52006-07-03 13:01:35 +00001792- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
1793 even if some data are received.
1794
Martin v. Löwis45482392006-07-03 12:28:58 +00001795- Bug #1267547: Put proper recursive setup.py call into the
1796 spec file generated by bdist_rpm.
1797
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001798- Bug #1514693: Update turtle's heading when switching between
1799 degrees and radians.
1800
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001801- Reimplement turtle.circle using a polyline, to allow correct
Martin v. Löwis2b88f632006-07-03 10:19:49 +00001802 filling of arcs.
Martin v. Löwis4c4300d2006-07-03 10:05:30 +00001803
Martin v. Löwisbd39c032006-07-03 09:44:00 +00001804- Bug #1514703: Only setup canvas window in turtle when the canvas
1805 is created.

1811 attribute values.
1812
1813- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
1814 sgmllib ('[' and ']' were not accepted).
1815
Georg Brandl1be63af2006-06-28 20:23:25 +00001816- Fix a bug in the turtle module's end_fill function.
1817
Brett Cannon53ab5b72006-06-22 16:49:14 +00001818- Bug #1510580: The 'warnings' module improperly required that a Warning
1819 category be either a types.ClassType and a subclass of Warning. The proper
1820 check is just that it is a subclass with Warning as the documentation states.
1821
Georg Brandlad29e632006-06-21 17:45:17 +00001822- The compiler module now correctly compiles the new try-except-finally
1823 statement (bug #1509132).
1824
Neal Norwitz60373cd2006-06-22 06:30:50 +00001825- The wsgiref package is now installed properly on Unix.
1826
Vinay Sajip28e57612006-07-01 10:45:20 +00001827- A bug was fixed in logging.config.fileConfig() which caused a crash on
1828 shutdown when fileConfig() was called multiple times.
1829
Gerhard Häring762fbd32006-07-02 17:48:30 +00001830- The sqlite3 module did cut off data from the SQLite database at the first
1831 null character before sending it to a custom converter. This has been fixed
1832 now.
1833
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001834Extension Modules
1835-----------------
1836
Tim Peters112aad32006-07-19 00:03:19 +00001837- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
1838 means that select() on sockets > FD_SETSIZE (typically 1024) work again.
1839 The patch makes sockets use poll() internally where available.
Anthony Baxter93ab5fa2006-07-11 02:04:09 +00001840
Thomas Hellerb9cb84f2006-07-10 11:17:37 +00001841- Assigning None to pointer type fields in ctypes structures possible
1842 overwrote the wrong fields, this is fixed now.
1843
1844- Fixed a segfault in _ctypes when ctypes.wintypes were imported
1845 on non-Windows platforms.
1846
1847- Bug #1518190: The ctypes.c_void_p constructor now accepts any
1848 integer or long, without range checking.
1849
1850- Patch #1517790: It is now possible to use custom objects in the ctypes
1851 foreign function argtypes sequence as long as they provide a from_param
1852 method, no longer is it required that the object is a ctypes type.
1853
1854- The '_ctypes' extension module now works when Python is configured
1855 with the --without-threads option.
1856
Martin v. Löwisee1e06d2006-07-02 18:44:00 +00001857- Bug #1513646: os.access on Windows now correctly determines write
1858 access, again.
1859
Neal Norwitz0f8b31a2006-06-28 06:28:31 +00001860- Bug #1512695: cPickle.loads could crash if it was interrupted with
1861 a KeyboardInterrupt.
1862
Neal Norwitza12aa882006-07-06 06:45:08 +00001863- Bug #1296433: parsing XML with a non-default encoding and
1864 a CharacterDataHandler could crash the interpreter in pyexpat.
1865
Neal Norwitz2a30cd02006-07-10 01:18:57 +00001866- Patch #1516912: improve Modules support for OpenVMS.
1867
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001868Build
1869-----
1870
Martin v. Löwisd73168d2006-07-14 09:58:55 +00001871- Automate Windows build process for the Win64 SSL module.
1872
Tim Peters32a83612006-07-10 21:08:24 +00001873- 'configure' now detects the zlib library the same way as distutils.
Thomas Woutersfc34f6c2006-07-06 10:48:28 +00001874 Previously, the slight difference could cause compilation errors of the
1875 'zlib' module on systems with more than one version of zlib.
1876
Martin v. Löwis4cbd05c2006-07-06 07:05:21 +00001877- The MSI compileall step was fixed to also support a TARGETDIR
1878 with spaces in it.
1879
Martin v. Löwis88ef6372006-07-06 06:55:58 +00001880- Bug #1517388: sqlite3.dll is now installed on Windows independent
1881 of Tcl/Tk.
1882
Neal Norwitzc315a0f2006-06-27 04:28:56 +00001883- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
Neal Norwitz3b6b8012006-06-27 04:12:58 +00001884 trying to be installed even though it's empty.
Georg Brandlad29e632006-06-21 17:45:17 +00001885
Neal Norwitzb15ac312006-06-29 04:10:08 +00001886Tests
1887-----
1888
1889- Call os.waitpid() at the end of tests that spawn child processes in order
1890 to minimize resources (zombies).
1891
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001892Documentation
1893-------------
1894
Nick Coghlan2d792252006-07-06 13:47:18 +00001895- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
1896 documentation for the warnings module.
1897
Martin v. Löwis1bf59592006-06-29 18:58:44 +00001898- Patch #1509163: MS Toolkit Compiler no longer available.
1899
Neal Norwitz56640df2006-07-10 02:36:41 +00001900- Patch #1504046: Add documentation for xml.etree.

Nick Coghlanc649ec52006-05-29 12:43:05 +00001903What's New in Python 2.5 beta 1?
Georg Brandlad29e632006-06-21 17:45:17 +00001904================================
Anthony Baxter51bcb682006-04-05 14:51:42 +00001905
Anthony Baxterd1136802006-06-19 12:04:15 +00001906*Release date: 20-JUN-2006*
Anthony Baxter51bcb682006-04-05 14:51:42 +00001907
1908Core and builtins
1909-----------------
1910
Georg Brandla56b9152006-06-19 06:35:54 +00001911- Patch #1507676: Error messages returned by invalid abstract object operations
1912 (such as iterating over an integer) have been improved and now include the
1913 type of the offending object to help with debugging.
1914
Brett Cannonea3912b2006-06-13 21:46:41 +00001915- Bug #992017: A classic class that defined a __coerce__() method that returned
1916 its arguments swapped would infinitely recurse and segfault the interpreter.
1917
Neal Norwitz909eb122006-06-12 02:13:21 +00001918- Fix the socket tests so they can be run concurrently.
1919
Neal Norwitzb9845e72006-06-12 02:11:18 +00001920- Removed 5 integers from C frame objects (PyFrameObject).
Vinay Sajip28e57612006-07-01 10:45:20 +00001921 f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
Neal Norwitzb9845e72006-06-12 02:11:18 +00001922
Brett Cannon22565aa2006-06-09 22:31:23 +00001923- Bug #532646: object.__call__() will continue looking for the __call__
1924 attribute on objects until one without one is found. This leads to recursion
1925 when you take a class and set its __call__ attribute to an instance of the
1926 class. Originally fixed for classic classes, but this fix is for new-style.
1927 Removes the infinite_rec_3 crasher.
1928
Georg Brandl24250812006-06-09 18:45:48 +00001929- The string and unicode methods startswith() and endswith() now accept
1930 a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
1931
Brett Cannonde3b0522006-06-08 17:00:45 +00001932- Buffer objects, at the C level, never used the char buffer
1933 implementation even when the char buffer for the wrapped object was
1934 explicitly requested (originally returned the read or write buffer).
1935 Now a TypeError is raised if the char buffer is not present but is
1936 requested.
1937
Georg Brandlddbaa662006-06-04 21:56:52 +00001938- Patch #1346214: Statements like "if 0: suite" are now again optimized
1939 away like they were in Python 2.4.
1940
Georg Brandlb7c8f542006-05-27 12:30:25 +00001941- Builtin exceptions are now full-blown new-style classes instead of
1942 instances pretending to be classes, which speeds up exception handling
1943 by about 80% in comparison to 2.5a2.
1944
Martin v. Löwisd004fc82006-05-27 08:36:52 +00001945- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
1946 Unicode 4.1.
1947
Georg Brandlf4ef1162006-05-26 18:03:31 +00001948- Patch #921466: sys.path_importer_cache is now used to cache valid and
1949 invalid file paths for the built-in import machinery which leads to
1950 fewer open calls on startup.
1951
Tim Peters696cf432006-05-24 21:10:40 +00001952- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
1953 of-2 bases. The largest speedup is for inputs with about 1000 decimal
1954 digits. Conversion from non-power-of-2 bases remains quadratic-time in
1955 the number of input digits (it was and remains linear-time for bases
1956 2, 4, 8, 16 and 32).
1957
Tim Petersb713ec22006-05-23 18:45:30 +00001958- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
1959 when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
1960 an integer close to ``sys.maxint``. This was repaired by patch
1961 #1335972, which also gives a nice speedup.
1962
Richard Jonescebbefc2006-05-23 18:28:17 +00001963- Patch #1337051: reduced size of frame objects.
1964
1965- PyErr_NewException now accepts a tuple of base classes as its
1966 "base" parameter.
1967
Richard Jones7c88dcc2006-05-23 10:37:38 +00001968- Patch #876206: function call speedup by retaining allocated frame
1969 objects.
1970
Georg Brandl7b90e162006-05-18 07:01:27 +00001971- Bug #1462152: file() now checks more thoroughly for invalid mode
1972 strings and removes a possible "U" before passing the mode to the
1973 C library function.
1974
Neal Norwitz1004a532006-05-15 07:17:23 +00001975- Patch #1488312, Fix memory alignment problem on SPARC in unicode
1976
Neal Norwitz373f0a72006-05-15 07:04:36 +00001977- Bug #1487966: Fix SystemError with conditional expression in assignment
1978
Martin v. Löwis879768d2006-05-11 13:28:43 +00001979- WindowsError now has two error code attributes: errno, which carries
1980 the error values from errno.h, and winerror, which carries the error
1981 values from winerror.h. Previous versions put the winerror.h values
1982 (from GetLastError()) into the errno attribute.
1983
Martin v. Löwis77736712006-05-04 05:51:03 +00001984- Patch #1475845: Raise IndentationError for unexpected indent.
1985
Neal Norwitzc4edb0e2006-05-02 04:43:14 +00001986- Patch #1479181: split open() and file() from being aliases for each other.
1987
Tim Peters44bd9862006-06-01 13:49:23 +00001988- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
1989 methods were always silently ignored by dictionaries when comparing keys.
1990 They are now passed through (except when using the C API function
1991 ``PyDict_GetItem()``, whose semantics did not change).
1992
1993- Bug #1456209: In some obscure cases it was possible for a class with a
1994 custom ``__eq__()`` method to confuse dict internals when class instances
1995 were used as a dict's keys and the ``__eq__()`` method mutated the dict.
1996 No, you don't have any code that did this ;-)

1999-----------------
2000
Trent Mick960a3f82006-06-28 20:30:41 +00002001- Bug #1295808: expat symbols should be namespaced in pyexpat
2002
2003- Patch #1462338: Upgrade pyexpat to expat 2.0.0
2004
Brett Cannon6ee7d012006-06-08 16:23:04 +00002005- Change binascii.hexlify to accept a read-only buffer instead of only a char
2006 buffer and actually follow its documentation.
2007
Hye-Shik Chang58ce5bc2006-06-05 00:59:54 +00002008- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
2009
Nick Coghlanc649ec52006-05-29 12:43:05 +00002010- Patch #1478788 (modified version): The functional extension module has
2011 been renamed to _functools and a functools Python wrapper module added.
2012 This provides a home for additional function related utilities that are
2013 not specifically about functional programming. See PEP 309.
2014
Bob Ippolito7ccc95a2006-05-23 19:11:34 +00002015- Patch #1493701: performance enhancements for struct module.

Georg Brandl378d5922006-05-17 14:26:50 +00002017- Patch #1490224: time.altzone is now set correctly on Cygwin.
2018
Georg Brandl8d3342b2006-05-16 07:38:27 +00002019- Patch #1435422: zlib's compress and decompress objects now have a
2020 copy() method.
2021
Andrew MacIntyre92913322006-06-13 15:04:24 +00002022- Patch #1454481: thread stack size is now tunable at runtime for thread
2023 enabled builds on Windows and systems with Posix threads support.
2024
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002025- On Win32, os.listdir now supports arbitrarily-long Unicode path names
2026 (up to the system limit of 32K characters).
2027
2028- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
2029 As a result, these functions now raise WindowsError instead of OSError.
2030
Tim Peters7a822da2006-05-25 21:50:17 +00002031- ``time.clock()`` on Win64 should use the high-performance Windows
2032 ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
2033 Windows platforms).
2034
Neal Norwitz7a5fc282006-05-15 06:48:14 +00002035- Calling Tk_Init twice is refused if the first call failed as that
2036 may deadlock.
2037
Gregory P. Smith0459e4d2006-06-05 02:02:25 +00002038- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
2039 accept it without potentially using an uninitialized pointer.
2040
2041- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
2042 assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
2043 patch numbers 1494885 and 1494902]

2047
Gregory P. Smith372b5832006-06-05 18:48:21 +00002048- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
2049 parameter is supplied. [SF pybsddb bug #1477863]
2050
Gregory P. Smith3c228b12006-06-05 23:59:37 +00002051- bsddb: the __len__ method of a DB object has been fixed to return correct
2052 results. It could previously incorrectly return 0 in some cases.
2053 Fixes SF bug 1493322 (pybsddb bug 1184012).
2054
Gregory P. Smithff7d9912006-06-08 05:17:08 +00002055- bsddb: the bsddb.dbtables Modify method now raises the proper error and
2056 aborts the db transaction safely when a modifier callback fails.
2057 Fixes SF python patch/bug #1408584.
2058
Gregory P. Smith506f7b52006-06-15 08:52:32 +00002059- bsddb: multithreaded DB access using the simple bsddb module interface
Vinay Sajip28e57612006-07-01 10:45:20 +00002060 now works reliably. It has been updated to use automatic BerkeleyDB
Gregory P. Smith506f7b52006-06-15 08:52:32 +00002061 deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
2062 database calls that would previously deadlock. [SF python bug #775414]

2093
Tim Peters43898b42006-06-14 04:09:25 +00002094- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
2095 guarantee that adjacent triples in the return list always describe
2096 non-adjacent blocks. Previously, a pair of matching blocks could end
2097 up being described by multiple adjacent triples that formed a partition
2098 of the matching pair.

2107
Andrew M. Kuchling0873b112006-06-09 16:46:51 +00002108- The wsgiref package has been added to the standard library.
2109
Nick Coghlan676725d2006-06-08 13:54:49 +00002110- The functions update_wrapper() and wraps() have been added to the functools
2111 module. These make it easier to copy relevant metadata from the original
2112 function when writing wrapper functions.
2113
Tim Petersd6a9eef2006-06-05 01:48:21 +00002114- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
2115 ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
Tim Petersbf0400a2006-06-05 01:43:03 +00002116
Martin v. Löwis3f767792006-06-04 19:36:28 +00002117- Patch #1359618: Speed up charmap encoder by using a trie structure
2118 for lookup.
2119
Tim Petersd609b1a2006-06-02 23:22:51 +00002120- The functions in the ``pprint`` module now sort dictionaries by key
2121 before computing the display. Before 2.5, ``pprint`` sorted a dictionary
2122 if and only if its display required more than one line, although that
2123 wasn't documented. The new behavior increases predictability; e.g.,
2124 using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
2125
Georg Brandlfd9a4b12006-05-29 20:57:01 +00002126- Patch #1497027: try HTTP digest auth before basic auth in urllib2

2135
Georg Brandlb89316f2006-05-17 15:51:16 +00002136- Patch #1180296: Two new functions were added to the locale module:
2137 format_string() to get the effect of "format % items" but locale-aware,
2138 and currency() to format a monetary number with currency sign.

2151 a couple of issues, notably handling of long file names using the
2152 GNU LONGNAME extension.
2153
2154- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
2155 new flag when ``name`` is already the name of an option flag.
2156
2157- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
2158 package.
2159
2160- Patch #1472854: make the rlcompleter.Completer class usable on non-

2201Core and builtins
2202-----------------
2203
Thomas Heller1b046642006-04-18 18:51:06 +00002204- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
2205 by converting these apis from macros into exported functions again:
2206
2207 PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
2208 PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
2209 PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
2210 PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
2211 PyRun_String Py_CompileString
2212
Martin v. Löwis45294a92006-04-18 06:24:08 +00002213- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
2214
Martin v. Löwis19ab6c92006-04-16 18:55:50 +00002215- All uses of PyStructSequence_InitType have been changed to initialize
2216 the type objects only once, even if the interpreter is initialized
2217 multiple times.
2218
Neal Norwitz61546162006-04-14 05:20:28 +00002219- Bug #1454485, array.array('u') could crash the interpreter. This was
2220 due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
2221 to unicode when it didn't make sense. 'u#' now requires a unicode string.
2222
2223- Py_UNICODE is unsigned. It was always documented as unsigned, but
2224 due to a bug had a signed value in previous versions.
2225
Tim Peters3a5e8b12006-04-11 01:44:07 +00002226- Patch #837242: ``id()`` of any Python object always gives a positive
2227 number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
2228 ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
Tim Peters527f6522006-04-11 01:47:17 +00002229 never been correct to implement a ``__hash()__`` method that returns the
Tim Peters3a5e8b12006-04-11 01:44:07 +00002230 ``id()`` of an object:
Martin v. Löwis0bc2ab92006-04-10 20:28:17 +00002231
Tim Peters3a5e8b12006-04-11 01:44:07 +00002232 def __hash__(self):
2233 return id(self) # WRONG
2234
2235 because a hash result must be a (short) Python int but it was always
2236 possible for ``id()`` to return a Python long. However, because ``id()``
Tim Peters527f6522006-04-11 01:47:17 +00002237 could return negative values before, on a 32-bit box an ``id()`` result
Tim Peters3a5e8b12006-04-11 01:44:07 +00002238 was always usable as a hash value before this patch. That's no longer
2239 necessarily so.
2240
2241- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
Anthony Baxter82201742006-04-09 15:07:40 +00002242 to load extension modules and now provides the dl module. As a result,
Tim Peters3a5e8b12006-04-11 01:44:07 +00002243 sys.setdlopenflags() now works correctly on these systems. (SF patch
Anthony Baxter82201742006-04-09 15:07:40 +00002244 #1454844)
2245
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002246- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
2247 involving generators that have paused outside of any ``try`` or ``with``
2248 blocks. (In 2.5a1, a paused generator that was part of a reference
2249 cycle could not be garbage collected, regardless of whether it was
2250 paused in a ``try`` or ``with`` block.)

2280 abusing errno.
2281
Tim Peters711bf302006-04-25 03:31:36 +00002282- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
2283 a doctest to be skipped (the code is not run, and the expected output
2284 or exception is ignored).
2285
Nick Coghlanda2268f2006-04-24 04:37:15 +00002286- Fixed contextlib.nested to cope with exceptions being raised and
2287 caught inside exit handlers.
2288
Greg Wardab05edc2006-04-23 03:47:58 +00002289- Updated optparse module to Optik 1.5.1 (allow numeric constants in
2290 hex, octal, or binary; add ``append_const`` action; keep going if
2291 gettext cannot be imported; added ``OptionParser.destroy()`` method;
2292 added ``epilog`` for better help generation).
2293
Tim Peters21fbd572006-04-21 21:18:10 +00002294- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
2295 called from a thread spawned as a side effect of importing a module.
2296
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002297- The pydoc module now supports documenting packages contained in
2298 .zip or .egg files.
2299
2300- The pkgutil module now has several new utility functions, such
2301 as ``walk_packages()`` to support working with packages that are either
2302 in the filesystem or zip files.
2303
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002304- The mailbox module can now modify and delete messages from
2305 mailboxes, in addition to simply reading them. Thanks to Gregory
2306 K. Johnson for writing the code, and to the 2005 Google Summer of
2307 Code for funding his work.
Phillip J. Eby17a35f92006-04-18 16:45:14 +00002308
Tim Petersc7605f22006-04-17 21:12:33 +00002309- The ``__del__`` method of class ``local`` in module ``_threading_local``
2310 returned before accomplishing any of its intended cleanup.
2311
Martin v. Löwisbd30f522006-04-17 17:08:37 +00002312- Patch #790710: Add breakpoint command lists in pdb.

Martin v. Löwis4be4e652006-04-17 19:25:49 +00002338- The Makefile now has a reindent target, which runs reindent.py on
2339 the library.
2340
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002341- Patch #1470875: Building Python with MS Free Compiler
2342
Martin v. Löwisc90b17e2006-04-15 08:13:05 +00002343- Patch #1161914: Add a python-config script.
Martin v. Löwis48bbaf22006-04-15 18:06:54 +00002344
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002345- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
2346 --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
Andrew M. Kuchlingdb4018f2006-04-14 14:54:18 +00002347 specified. (Can be overridden by explicitly setting LINKCC.) Decouple
Martin v. Löwis0f48d982006-04-14 14:34:26 +00002348 CXX from --with-cxx-main, see description in README.
2349
Martin v. Löwis10acfd02006-04-10 12:39:36 +00002350- Patch #1429775: Link extension modules with the shared libpython.
2351
Hye-Shik Changf4795c82006-04-26 19:20:26 +00002352- Fixed a libffi build problem on MIPS systems.
2353
Tim Peters8931ff12006-05-13 23:28:20 +00002354- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
2355 now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
2356 and "%zu" for unsigned integers of type ``size_t``.
2357
Anthony Baxter51bcb682006-04-05 14:51:42 +00002358Tests
2359-----
2360
Nick Coghlanda2268f2006-04-24 04:37:15 +00002361- test_contextlib now checks contextlib.nested can cope with exceptions
2362 being raised and caught inside exit handlers.
2363
Nick Coghlan27ec1a72006-04-24 04:32:47 +00002364- test_cmd_line now checks operation of the -m and -c command switches
2365
Phillip J. Eby51dd7d92006-04-11 01:21:31 +00002366- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
2367 it separately and by hand. It also wasn't cleaning up its changes to
2368 the current Decimal context.
2369
Thomas Woutersabd08882006-04-26 15:53:30 +00002370- regrtest.py now has a -M option to run tests that test the new limits of
2371 containers, on 64-bit architectures. Running these tests is only sensible
2372 on 64-bit machines with more than two gigabytes of memory. The argument
2373 passed is the maximum amount of memory for the tests to use.

Anthony Baxter51bcb682006-04-05 14:51:42 +00002381Documentation
2382-------------
2383
Tim Petersb06d28c2006-05-12 01:57:59 +00002384- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
2385
Nick Coghlanc195d8a2006-04-24 03:04:43 +00002386- PEP 343: Added Context Types section to the library reference
2387 and attempted to bring other PEP 343 related documentation into
2388 line with the implementation and/or python-dev discussions.
2389
Tim Peters8dc73d22006-04-24 02:03:16 +00002390- Bug #1337990: clarified that ``doctest`` does not support examples
2391 requiring both expected output and an exception.

Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002394What's New in Python 2.5 alpha 1?
2395=================================
2396
Anthony Baxterebed3f62006-04-03 15:03:44 +00002397*Release date: 05-APR-2006*
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002398
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002399Core and builtins
2400-----------------
2401
Nick Coghlan43832302006-04-23 17:04:07 +00002402- PEP 338: -m command line switch now delegates to runpy.run_module
2403 allowing it to support modules in packages and zipfiles
2404
Martin v. Löwisc661b882006-04-20 04:54:23 +00002405- On Windows, .DLL is not an accepted file name extension for
2406 extension modules anymore; extensions are only found if they
2407 end in .PYD.
2408
Martin v. Löwisea62d252006-04-03 10:56:49 +00002409- Bug #1421664: sys.stderr.encoding is now set to the same value as
2410 sys.stdout.encoding.
2411
Neal Norwitz92e212f2006-04-03 04:48:37 +00002412- __import__ accepts keyword arguments.
2413
Georg Brandlccadf842006-03-31 18:54:53 +00002414- Patch #1460496: round() now accepts keyword arguments.
2415
Anthony Baxter262c00a2006-03-30 10:53:17 +00002416- Fixed bug #1459029 - unicode reprs were double-escaped.
2417
Hye-Shik Changd478f342006-03-23 12:32:36 +00002418- Patch #1396919: The system scope threads are reenabled on FreeBSD
2419 5.4 and later versions.
2420
Neal Norwitze98ccf62006-03-23 05:39:47 +00002421- Bug #1115379: Compiling a Unicode string with an encoding declaration
2422 now gives a SyntaxError.
2423
Georg Brandlabd1ff82006-03-18 07:59:59 +00002424- Previously, Python code had no easy way to access the contents of a
2425 cell object. Now, a ``cell_contents`` attribute has been added
2426 (closes patch #1170323).
2427
Tim Peterscf79aac2006-03-16 01:14:46 +00002428- Patch #1123430: Python's small-object allocator now returns an arena to
2429 the system ``free()`` when all memory within an arena becomes unused
2430 again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
2431 freed. Some applications will see a drop in virtual memory size now,
2432 especially long-running applications that, from time to time, temporarily
2433 use a large number of small objects. Note that when Python returns an
2434 arena to the platform C's ``free()``, there's no guarantee that the
Andrew M. Kuchling1da4a942006-04-22 02:32:43 +00002435 platform C library will in turn return that memory to the operating system.
2436 The effect of the patch is to stop making that impossible, and in tests it
Tim Peterscf79aac2006-03-16 01:14:46 +00002437 appears to be effective at least on Microsoft C and gcc-based systems.
2438 Thanks to Evan Jones for hard work and patience.
2439
Georg Brandl533ff6f2006-03-08 18:09:27 +00002440- Patch #1434038: property() now uses the getter's docstring if there is
2441 no "doc" argument given. This makes it possible to legitimately use
2442 property() as a decorator to produce a read-only property.
2443
Guido van Rossum9aa37ab2006-03-07 18:54:08 +00002444- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
2445 nb_index slot to the PyNumberMethods struct. The slot is consulted instead
2446 of requiring an int or long in slicing and a few other contexts, enabling
2447 other objects (e.g. Numeric Python's integers) to be used as slice indices.
2448
Neal Norwitz995acdf2006-03-07 05:01:00 +00002449- Fixed various bugs reported by Coverity's Prevent tool.
2450
Brett Cannonbf364092006-03-01 04:25:17 +00002451- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
2452 new exception base class, BaseException, which has a new message attribute.
2453 KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
2454 Raising a string exception now raises a DeprecationWarning.
2455
Thomas Woutersfb609f42006-02-28 16:37:25 +00002456- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
2457 explicitly relative, using 'from .module import name' to mean 'from the same
2458 package as this module is in. Imports without dots still default to the
2459 old relative-then-absolute, unless 'from __future__ import
2460 absolute_import' is used.
2461
Brett Cannona7446e32006-02-27 23:39:10 +00002462- Properly check if 'warnings' raises an exception (usually when a filter set
2463 to "error" is triggered) when raising a warning for raising string
2464 exceptions.
2465
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002466- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
Neal Norwitz0023a2f2006-02-27 23:24:48 +00002467 The name was removed from Include/code.h.
2468
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002469- PEP 308: conditional expressions were added: (x if cond else y).
Neal Norwitzeb651252006-02-27 16:47:12 +00002470
Guido van Rossum1968ad32006-02-25 22:38:04 +00002471- Patch 1433928:
2472 - The copy module now "copies" function objects (as atomic objects).
2473 - dict.__getitem__ now looks for a __missing__ hook before raising
2474 KeyError.
2475
Tim Peters84ef21c2006-02-28 20:39:06 +00002476- PEP 343: with statement implemented. Needs ``from __future__ import
2477 with_statement``. Use of 'with' as a variable will generate a warning.
2478 Use of 'as' as a variable will also generate a warning (unless it's
Neal Norwitz055ec242006-02-28 20:06:49 +00002479 part of an import statement).
Guido van Rossum1a5e21e2006-02-28 21:57:43 +00002480 The following objects have __context__ methods:
2481 - The built-in file type.
2482 - The thread.LockType type.
2483 - The following types defined by the threading module:
2484 Lock, RLock, Condition, Semaphore, BoundedSemaphore.
2485 - The decimal.Context class.
Guido van Rossumc2e20742006-02-27 22:32:47 +00002486
Marc-André Lemburgfe4b34c2006-02-19 15:22:22 +00002487- Fix the encodings package codec search function to only search
2488 inside its own package. Fixes problem reported in patch #1433198.
2489
2490 Note: Codec packages should implement and register their own
2491 codec search function. PEP 100 has the details.
2492
Tim Peters9ea89d22006-06-04 03:26:02 +00002493- PEP 353: Using ``Py_ssize_t`` as the index type.
2494
2495- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
2496 info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
2497 now allow Python to make use of memory blocks exceeding 2**32 bytes for
2498 some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
2499 to 4-byte allocations before.
Martin v. Löwis18e16552006-02-15 17:27:45 +00002500
Neal Norwitzfc76d632006-01-10 06:03:13 +00002501- Patch #1400181, fix unicode string formatting to not use the locale.
2502 This is how string objects work. u'%f' could use , instead of .
2503 for the decimal point. Now both strings and unicode always use periods.
2504
Neal Norwitz671b9e32006-01-09 07:07:12 +00002505- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
2506 configure would break checking curses.h.
2507
Georg Brandlcd4d1e82005-12-27 17:37:07 +00002508- Bug #959576: The pwd module is now builtin. This allows Python to be
2509 built on UNIX platforms without $HOME set.
2510
Neal Norwitzc10978f2005-12-19 06:07:16 +00002511- Bug #1072182, fix some potential problems if characters are signed.
2512
Neal Norwitz5d0ad502005-12-19 04:27:42 +00002513- Bug #889500, fix line number on SyntaxWarning for global declarations.
2514
Neal Norwitzdb83eb32005-12-18 05:29:30 +00002515- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
2516
Neal Norwitze7214a12005-12-18 05:03:17 +00002517- Support for converting hex strings to floats no longer works.
2518 This was not portable. float('0x3') now raises a ValueError.
2519
Barry Warsaw2a38a862005-12-18 01:27:35 +00002520- Patch #1382163: Expose Subversion revision number to Python. New C API
Barry Warsawd3c38ff2006-03-07 09:46:03 +00002521 function Py_GetBuildNumber(). New attribute sys.subversion. Build number
Barry Warsaw2a38a862005-12-18 01:27:35 +00002522 is now displayed in interactive prompt banner.
2523
Georg Brandlfa166682005-12-17 21:45:17 +00002524- Implementation of PEP 341 - Unification of try/except and try/finally.
2525 "except" clauses can now be written together with a "finally" clause in
Neal Norwitz11ca77e2005-12-17 22:24:12 +00002526 one try statement instead of two nested ones. Patch #1355913.
Georg Brandlfa166682005-12-17 21:45:17 +00002527
Hye-Shik Chang835b2432005-12-17 04:38:31 +00002528- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
2529 now encodes backslash correctly.
2530
Martin v. Löwisb45b3152005-11-28 17:34:23 +00002531- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
2532
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002533- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
Georg Brandlf06e30a2005-11-24 15:37:42 +00002534 and long longs.
2535
Neal Norwitz67715f02005-11-09 06:59:35 +00002536- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
Tim Peters3a5e8b12006-04-11 01:44:07 +00002537 It was possible for dlerror() to return a NULL pointer, so
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002538 it will now use a default error message in this case.
Neal Norwitz67715f02005-11-09 06:59:35 +00002539
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002540- Replaced most Unicode charmap codecs with new ones using the
2541 new Unicode translate string feature in the builtin charmap
2542 codec; the codecs were created from the mapping tables available
2543 at ftp.unicode.org and contain a few updates (e.g. the Mac OS
2544 encodings now include a mapping for the Apple logo)
2545
Tim Peterse3547fd2005-12-16 23:13:57 +00002546- Added a few more codecs for Mac OS encodings
Marc-André Lemburga5bafc42005-10-23 13:43:40 +00002547
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002548- Sped up some Unicode operations.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002549
Martin v. Löwisbd260da2006-02-26 19:42:26 +00002550- A new AST parser implementation was completed. The abstract
2551 syntax tree is available for read-only (non-compile) access
Martin v. Löwis577b5b92006-02-27 15:23:19 +00002552 to Python code; an _ast module was added.
Neal Norwitzfed9b3e2005-10-21 06:32:02 +00002553
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002554- SF bug #1167751: fix incorrect code being produced for generator expressions.
Neal Norwitz16af7342005-10-21 06:25:33 +00002555 The following code now raises a SyntaxError: foo(a = i for i in range(10))
2556
Neal Norwitz708e51a2005-10-03 04:48:15 +00002557- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
2558
Neal Norwitz11bd1192005-10-03 00:54:56 +00002559- SF Bug #887946: fix segfault when redirecting stdin from a directory.
2560 Provide a warning when a directory is passed on the command line.
2561
Neal Norwitz40d37812005-10-02 01:48:49 +00002562- Fix segfault with invalid coding.
2563
2564- SF bug #772896: unknown encoding results in MemoryError.
2565
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002566- All iterators now have a Boolean value of True. Formerly, some iterators
Raymond Hettinger6b27cda2005-09-24 21:23:05 +00002567 supported a __len__() method which evaluated to False when the iterator
2568 was empty.
2569
Guido van Rossum630db602005-09-20 18:49:54 +00002570- On 64-bit platforms, when __len__() returns a value that cannot be
2571 represented as a C int, raise OverflowError.
2572
Skip Montanarof8948ca2005-09-19 03:54:46 +00002573- test__locale is skipped on OS X < 10.4 (only partial locale support is
Walter Dörwald6611a8b2005-10-09 19:28:35 +00002574 present).
Skip Montanarof8948ca2005-09-19 03:54:46 +00002575
Georg Brandl80bbf3f2005-09-14 19:38:29 +00002576- SF bug #893549: parsing keyword arguments was broken with a few format
2577 codes.
2578
Guido van Rossum8ee3e5a2005-09-14 18:09:42 +00002579- Changes donated by Elemental Security to make it work on AIX 5.3
2580 with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
2581 bug #105470: test_pwd fails on 64bit system (Opteron).
2582
Guido van Rossum539c6622005-09-14 17:49:54 +00002583- Changes donated by Elemental Security to make it work on HP-UX 11 on
2584 Itanium2 with HP's 64-bit compiler (SF patch #1225212).
2585
Georg Brandl4550b8d2005-08-26 06:43:52 +00002586- Disallow keyword arguments for type constructors that don't use them
Georg Brandl02c42872005-08-26 06:42:30 +00002587 (fixes bug #1119418).
2588
Martin v. Löwisd35edda2005-08-24 08:39:24 +00002589- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
2590
Barry Warsawe2eca0b2005-08-15 18:14:19 +00002591- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
2592 exceptions that cause a function to exit.
2593
Raymond Hettinger9f1a6792005-07-31 01:16:36 +00002594- The implementation of set() and frozenset() was revised to use its
2595 own internal data structure. Memory consumption is reduced by 1/3
2596 and there are modest speed-ups as well. The API is unchanged.
2597
Tim Petersde7990b2005-07-17 23:45:23 +00002598- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
2599
Michael W. Hudson0edc7a02005-07-12 10:21:19 +00002600- SF bug #1229429: PyObject_CallMethod failed to decrement some
2601 reference counts in some error exit cases.
2602
Tim Petersecc6e6a2005-07-10 22:30:55 +00002603- SF bug #1185883: Python's small-object memory allocator took over
2604 a block managed by the platform C library whenever a realloc specified
2605 a small new size. However, there's no portable way to know then how
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00002606 much of the address space following the pointer is valid, so there's no
Tim Petersecc6e6a2005-07-10 22:30:55 +00002607 portable way to copy data from the C-managed block into Python's
2608 small-object space without risking a memory fault. Python's small-object
2609 realloc now leaves such blocks under the control of the platform C
2610 realloc.

Michael W. Hudsonb8963812005-07-05 15:21:58 +00002612- SF bug #1232517: An overflow error was not detected properly when
2613 attempting to convert a large float to an int in os.utime().
2614
Raymond Hettinger3296e692005-06-29 23:29:56 +00002615- SF bug #1224347: hex longs now print with lowercase letters just
2616 like their int counterparts.
2617
Michael W. Hudson188d4362005-06-20 16:52:57 +00002618- SF bug #1163563: the original fix for bug #1010677 ("thread Module
2619 Breaks PyGILState_Ensure()") broke badly in the case of multiple
2620 interpreter states; back out that fix and do a better job (see
2621 http://mail.python.org/pipermail/python-dev/2005-June/054258.html
2622 for a longer write-up of the problem).
2623
Michael W. Hudsondf888462005-06-03 14:41:55 +00002624- SF patch #1180995: marshal now uses a binary format by default when
2625 serializing floats.
2626
Michael W. Hudsonda85a902005-06-01 11:34:22 +00002627- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
2628 the routines that promise to produce IEEE 754 binary representations
2629 of floats now simply copy bytes around.
2630
Skip Montanarobbf12ba2005-05-20 03:07:06 +00002631- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
2632 278.
2633
Brett Cannonc3647ac2005-04-26 03:45:26 +00002634- patch #1109424: int, long, float, complex, and unicode now check for the
2635 proper magic slot for type conversions when subclassed. Previously the
2636 magic slot was ignored during conversion. Semantics now match the way
2637 subclasses of str always behaved. int/long/float, conversion of an instance
Walter Dörwald78a78b02005-09-01 12:04:29 +00002638 to the base class has been moved to the proper nb_* magic slot and out of
Brett Cannonc3647ac2005-04-26 03:45:26 +00002639 PyNumber_*().
Neal Norwitzcfba5f82006-04-25 05:05:03 +00002640 Thanks Walter D�rwald.
Brett Cannonc3647ac2005-04-26 03:45:26 +00002641
Barry Warsawc8d907c2005-04-19 23:43:40 +00002642- Descriptors defined in C with a PyGetSetDef structure, where the setter is
2643 NULL, now raise an AttributeError when attempting to set or delete the
2644 attribute. Previously a TypeError was raised, but this was inconsistent
2645 with the equivalent pure-Python implementation.
2646
Michael W. Hudson774479c2005-04-18 08:46:17 +00002647- It is now safe to call PyGILState_Release() before
2648 PyEval_InitThreads() (note that if there is reason to believe there
2649 are multiple threads around you still must call PyEval_InitThreads()
2650 before using the Python API; this fix is for extension modules that
2651 have no way of knowing if Python is multi-threaded yet).
2652
Michael W. Hudsone3afc592005-04-07 10:11:19 +00002653- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
2654 disabled caused a crash.
2655
Michael W. Hudsonb330adf2005-03-31 09:35:44 +00002656- Bug #1165306: instancemethod_new allowed the creation of a method
2657 with im_class == im_self == NULL, which caused a crash when called.
2658
Tim Petersecc6e6a2005-07-10 22:30:55 +00002659- Move exception finalisation later in the shutdown process - this
Anthony Baxter12b6f6c2005-03-29 13:36:16 +00002660 fixes the crash seen in bug #1165761
2661
Raymond Hettinger96229b12005-03-11 06:49:40 +00002662- Added two new builtins, any() and all().
2663
Brett Cannon409d8f22005-03-05 06:47:57 +00002664- Defining a class with empty parentheses is now allowed
Brett Cannonf4189912005-04-09 02:30:16 +00002665 (e.g., ``class C(): pass`` is no longer a syntax error).
2666 Patch #1176012 added support to the 'parser' module and 'compiler' package
2667 (thanks to logistix for that added support).
Brett Cannon409d8f22005-03-05 06:47:57 +00002668
Martin v. Löwis96d743e2005-03-03 23:00:26 +00002669- Patch #1115086: Support PY_LONGLONG in structmember.
2670
Raymond Hettingerb67cc802005-03-03 16:45:19 +00002671- Bug #1155938: new style classes did not check that __init__() was
2672 returning None.
2673
Tim Petersecc6e6a2005-07-10 22:30:55 +00002674- Patch #802188: Report characters after line continuation character
Martin v. Löwis4bf108d2005-03-03 11:45:45 +00002675 ('\') with a specific error message.
2676
Martin v. Löwisff232d72005-03-03 09:24:38 +00002677- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
2678
Michael W. Hudson8e1afab2005-02-17 14:55:21 +00002679- Bug #1124295: the __name__ attribute of file objects was
2680 inadvertently made inaccessible in restricted mode.
2681
Tim Petersecc6e6a2005-07-10 22:30:55 +00002682- Bug #1074011: closing sys.std{out,err} now causes a flush() and
Martin v. Löwis8e3ca8a2005-01-23 09:41:49 +00002683 an ferror() call.
2684
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00002685- min() and max() now support key= arguments with the same meaning as in
2686 list.sort().
2687
Raymond Hettingerc34f8672005-01-02 06:17:33 +00002688- The peephole optimizer now performs simple constant folding in expressions:
2689 (2+3) --> (5).
2690
Raymond Hettingera422c342005-01-11 03:03:27 +00002691- set and frozenset objects can now be marshalled. SF #1098985.
2692
Michael W. Hudsonfaa76482005-01-31 17:09:25 +00002693- Bug #1077106: Poor argument checking could cause memory corruption
2694 in calls to os.read().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002695
Jeremy Hyltonab630502005-02-04 18:44:06 +00002696- The parser did not complain about future statements in illegal
2697 positions. It once again reports a syntax error if a future
2698 statement occurs after anything other than a doc string.
2699
Neil Schemenauercf52c072005-08-12 17:34:58 +00002700- Change the %s format specifier for str objects so that it returns a
2701 unicode instance if the argument is not an instance of basestring and
2702 calling __str__ on the argument returns a unicode instance.
2703
Tim Petersf4e69282006-02-27 17:15:31 +00002704- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
2705 current thread state when the auto-GIL-state machinery knows about
2706 it (since the thread state is being deleted, continuing to remember it
2707 can't help, but can hurt if another thread happens to get created with
2708 the same thread id).
2709
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002710Extension Modules
2711-----------------
2712

2727
2728- The following modules were removed: regsub, reconvert, regex, regex_syntax.
2729
2730- re and sre were swapped, so help(re) provides full help. importing sre
Neal Norwitzefbeaef2006-03-16 06:40:39 +00002731 is deprecated. The undocumented re.engine variable no longer exists.
2732

2735
Martin v. Löwis480f1bb2006-03-09 23:38:20 +00002736- The unicodedata module was updated to the 4.1 version of the Unicode
2737 database. The 3.2 version is still available as unicodedata.db_3_2_0
2738 for applications that require this specific version (such as IDNA).
2739
Neal Norwitzb62c4332006-03-04 18:35:47 +00002740- The timing module is no longer built by default. It was deprecated
2741 in PEP 4 in Python 2.0 or earlier.
2742
Guido van Rossum1968ad32006-02-25 22:38:04 +00002743- Patch 1433928: Added a new type, defaultdict, to the collections module.
2744 This uses the new __missing__ hook behavior added to dict (see above).
2745
Georg Brandldbd83392006-02-20 09:42:33 +00002746- Bug #854823: socketmodule now builds on Sun platforms even when

2761
Martin v. Löwis14694662006-02-03 12:54:16 +00002762- Use Win32 API to implement os.stat/fstat. As a result, subsecond timestamps
2763 are reported, the limit on path name lengths is removed, and stat reports
2764 WindowsError now (instead of OSError).
2765
Gregory P. Smithcfc4a8d2006-01-29 19:46:23 +00002766- Add bsddb.db.DBEnv.set_tx_timestamp allowing time based database recovery.

2841 the request code argument, which results in more C-like behaviour
2842 for large or negative values.
2843
Tim Petersecc6e6a2005-07-10 22:30:55 +00002844- Bug #1234979: For the argument of thread.Lock.acquire, the Windows

2886
Raymond Hettingerb2594052004-12-05 09:25:51 +00002887- itertools.islice() now accepts None for the start and step arguments.

Tim Peters112aad32006-07-19 00:03:19 +00002899
Georg Brandlc5e3d8a2006-07-17 13:26:33 +00002900- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
2901 been renamed to have only a single underscore prefix. This was done to
2902 make subclassing easier.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00002903
Nick Coghlan43832302006-04-23 17:04:07 +00002904- PEP 338: new module runpy defines a run_module function to support
2905 executing modules which provide access to source code or a code object
2906 via the PEP 302 import mechanisms.
2907
Anthony Baxter93f5b932006-04-03 08:05:07 +00002908- The email module's parsedate_tz function now sets the daylight savings

2916 in attribute values.
2917
Anthony Baxterc51ee692006-04-01 00:57:31 +00002918- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
Georg Brandl828fdef2006-04-01 08:59:03 +00002919 a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
Tim Peters3a5e8b12006-04-11 01:44:07 +00002920 later to build this - if you have an earlier version, the C extension
Anthony Baxterc51ee692006-04-01 00:57:31 +00002921 module will not be built.
2922
Tim Petersc17976e2006-04-01 00:26:53 +00002923- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
2924 aren't officially supported here, and trying to use them will probably
2925 raise an exception some day. But dicts have been allowed, and "mostly
2926 worked", so support for them won't go away without warning.
2927
Georg Brandl338ef7d2006-03-31 18:42:16 +00002928- Bug #1445068: getpass.getpass() can now be given an explicit stream
2929 argument to specify where to write the prompt.
2930
Georg Brandl22ec80b2006-03-31 18:25:44 +00002931- Patch #1462313, bug #1443328: the pickle modules now can handle classes

2940 to make it easier to monitor when daemon threads have completed
2941 processing all enqueued tasks. Patch #1455676.
2942
Martin v. Löwisbd8dbab2006-03-23 18:18:35 +00002943- popen2.Popen objects now preserve the command in a .cmd attribute.

2946
Barry Warsaw4d90bbd2006-03-22 02:45:50 +00002947- email 4.0 package now integrated. This is largely the same as the email 3.0
2948 package that was included in Python 2.3, except that PEP 8 module names are
2949 now used (e.g. mail.message instead of email.Message). The MIME classes
2950 have been moved to a subpackage (e.g. email.mime.text instead of
2951 email.MIMEText). The old names are still supported for now. Several
2952 deprecated Message methods have been removed and lots of bugs have been
2953 fixed. More details can be found in the email package documentation.
2954
Walter Dörwald40108c92006-03-27 08:15:44 +00002955- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
2956 (a subclass of tuple) that provides incremental decoders and encoders
2957 (a way to use stateful codecs without the stream API). Python functions
2958 codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
2959 as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
2960 have been added.
Walter Dörwaldabb02e52006-03-15 11:35:15 +00002961
Walter Dörwald067db482006-03-15 22:17:27 +00002962- Patch #1359365: Calling next() on a closed StringIO.String object raises
2963 a ValueError instead of a StopIteration now (like file and cString.String do).
2964 cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
2965 called before (like file and StringIO.StringIO do).
Walter Dörwald197e8322006-03-15 22:13:13 +00002966
Martin v. Löwis04824ce2006-03-10 21:26:16 +00002967- A regrtest option -w was added to re-run failed tests in verbose mode.

3040 historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
3041 In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
3042 Ronald L. Rivest offered this advice for Python:
3043
3044 "The consensus of researchers in this area (at least as
3045 expressed at the NIST Hash Function Workshop 10/31/05),
3046 is that SHA-256 is a good choice for the time being, but
3047 that research should continue, and other alternatives may
3048 arise from this research. The larger SHA's also seem OK."
Brett Cannon3cbd0382005-12-16 22:49:23 +00003049
Fredrik Lundh7e0aef02005-12-12 18:54:55 +00003050- Added a subset of Fredrik Lundh's ElementTree package. Available

Georg Brandl5284b532005-06-26 22:54:58 +00003134
Georg Brandl2f210b62005-06-26 22:09:06 +00003135- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
3136
Georg Brandlfbff1bc2005-06-26 21:36:25 +00003137- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
3138 error messages.
3139
Georg Brandl379f99d2005-06-26 21:09:38 +00003140- Bug #1108948: Cookie.py produced invalid JavaScript code.
3141
Raymond Hettingerda99d1c2005-06-21 07:43:58 +00003142- The tokenize module now detects and reports indentation errors.
3143 Bug #1224621.
3144
Raymond Hettinger68c04532005-06-10 11:05:19 +00003145- The tokenize module has a new untokenize() function to support a full
Andrew M. Kuchling7034f6b2006-04-01 10:50:08 +00003146 roundtrip from lexed tokens back to Python source code. In addition,
Raymond Hettinger68c04532005-06-10 11:05:19 +00003147 the generate_tokens() function now accepts a callable argument that
3148 terminates by raising StopIteration.
3149
Georg Brandl9166e1a2005-06-04 09:20:03 +00003150- Bug #1196315: fix weakref.WeakValueDictionary constructor.
3151
Georg Brandl268e61c2005-06-03 14:28:50 +00003152- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
3153 component of the path.
3154
Skip Montanaro174dd222005-05-14 20:54:16 +00003155- Patch #1120353: The xmlrpclib module provides better, more transparent,
3156 support for datetime.{datetime,date,time} objects. With use_datetime set
3157 to True, applications shouldn't have to fiddle with the DateTime wrapper
3158 class at all.
3159
Martin v. Löwis55f1bb82005-03-21 20:56:35 +00003160- distutils.commands.upload was added to support uploading distribution
3161 files to PyPI.
3162
Walter Dörwalda6e8a4a2005-03-31 13:57:38 +00003163- distutils.commands.register now encodes the data as UTF-8 before posting
3164 them to PyPI.
3165
Raymond Hettinger267b8682005-03-27 10:47:39 +00003166- decimal operator and comparison methods now return NotImplemented
3167 instead of raising a TypeError when interacting with other types. This
3168 allows other classes to implement __radd__ style methods and have them
3169 work as expected.
3170
Raymond Hettingerbea3f6f2005-03-15 04:59:17 +00003171- Bug #1163325: Decimal infinities failed to hash. Attempting to
3172 hash a NaN raised an InvalidOperation instead of a TypeError.
3173
Tim Petersecc6e6a2005-07-10 22:30:55 +00003174- Patch #918101: Add tarfile open mode r|* for auto-detection of the
Martin v. Löwis78be7df2005-03-05 12:47:42 +00003175 stream compression; add, for symmetry reasons, r:* as a synonym of r.
3176
Martin v. Löwis00a73e72005-03-04 19:40:34 +00003177- Patch #1043890: Add extractall method to tarfile.

3180 to build.
3181
Martin v. Löwis637431b2005-03-03 23:12:42 +00003182- Patch #1103407: Properly deal with tarfile iterators when untarring
3183 symbolic links on Windows.

3206
Raymond Hettingerbab41432005-02-05 01:31:19 +00003207- Fixed bug in a NameError bug in cookielib. Patch #1116583.
3208
Guido van Rossumd0641422005-02-03 15:01:24 +00003209- Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This
3210 disables recursive traversal through instance attributes, which can
3211 be exploited in various ways.
3212
Tim Peterse3547fd2005-12-16 23:13:57 +00003213- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
Andrew M. Kuchling3a976052005-12-04 15:07:41 +00003214 flags on the HTTP listening socket.
3215
Andrew M. Kuchlinge63fde72005-12-04 15:36:57 +00003216- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
3217 Fixed by reading the HTTP body in chunks instead of one big socket.read().
3218
Fred Drakefbdeaad2006-07-29 16:56:15 +00003219- Patches #893642, #1039083: add allow_none, encoding arguments to
3220 constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
Andrew M. Kuchling10a16de2005-12-04 16:34:40 +00003221
Martin v. Löwis1d11de62005-01-29 13:29:23 +00003222- Bug #1110478: Revert os.environ.update to do putenv again.
3223
Thomas Hellerd6c6e222005-01-20 19:20:16 +00003224- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
3225
Martin v. Löwis22b457e2005-01-16 08:40:58 +00003226- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
3227
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003228- Enhancements to the csv module:
3229
3230 + Dialects are now validated by the underlying C code, better
Georg Brandl7eb4b7d2005-07-22 21:49:32 +00003231 reflecting its capabilities, and improving its compliance with
Tim Petersecc6e6a2005-07-10 22:30:55 +00003232 PEP 305.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003233 + Dialect parameter parsing has been re-implemented to improve error
3234 reporting.
3235 + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
3236 dictates.
3237 + the parser now removes the escapechar prefix from escaped characters.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003238 + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
Andrew M. Kuchling6db67822006-04-18 14:04:57 +00003239 types, rather than any object that can be represented as a numeric.
Andrew McNamara0f0599d2005-01-12 09:45:18 +00003240 + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
3241 to floats.
Andrew McNamaraf69d94f2005-01-13 11:30:54 +00003242 + reader now allows \r characters to be quoted (previously it only allowed
3243 \n to be quoted).
Andrew McNamarac89f2842005-01-12 07:44:42 +00003244 + writer doublequote handling improved.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003245 + Dialect classes passed to the module are no longer instantiated by
3246 the module before being parsed (the former validation scheme required
3247 this, but the mechanism was unreliable).
3248 + The dialect registry now contains instances of the internal
3249 C-coded dialect type, rather than references to python objects.
3250 + the internal c-coded dialect type is now immutable.
3251 + register_dialect now accepts the same keyword dialect specifications
3252 as the reader and writer, allowing the user to register dialects
3253 without first creating a dialect class.
3254 + a configurable limit to the size of parsed fields has been added -
3255 previously, an unmatched quote character could result in the entire
3256 file being read into the field buffer before an error was reported.
Andrew McNamara31d88962005-01-12 03:45:10 +00003257 + A new module method csv.field_size_limit() has been added that sets
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003258 the parser field size limit (returning the former limit). The initial
3259 limit is 128kB.
Andrew McNamara7f2053e2005-01-12 11:17:16 +00003260 + A line_num attribute has been added to the reader object, which tracks
3261 the number of lines read from the source iterator. This is not
3262 the same as the number of records returned, as records can span
3263 multiple lines.
Andrew McNamaraa08eecb2005-01-12 03:25:27 +00003264 + reader and writer objects were not being registered with the cyclic-GC.
3265 This has been fixed.
3266
Brett Cannone6539c42005-01-08 02:43:53 +00003267- _DummyThread objects in the threading module now delete self.__block that is
3268 inherited from _Thread since it uses up a lock allocated by 'thread'. The
3269 lock primitives tend to be limited in number and thus should not be wasted on
3270 a _DummyThread object. Fixes bug #1089632.
3271
Raymond Hettinger97db05d2005-01-07 08:15:41 +00003272- The imghdr module now detects Exif files.
3273
Raymond Hettinger6065d322004-12-20 23:51:53 +00003274- StringIO.truncate() now correctly adjusts the size attribute.
3275 (Bug #951915).
3276
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003277- locale.py now uses an updated locale alias table (built using
3278 Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
3279 alias file); the encoding lookup was enhanced to use Python's
Andrew M. Kuchling88b85822005-08-23 00:57:07 +00003280 encoding alias table.
Marc-André Lemburgbb4f1bd2004-12-10 21:58:14 +00003281
Raymond Hettinger3557f422004-12-07 12:02:02 +00003282- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
3283
Raymond Hettingera6b45cc2004-12-07 07:05:57 +00003284- the pickle module no longer accepts the deprecated None option in the
3285 args tuple returned by __reduce__().
3286
Brett Cannon84667c02004-12-07 03:25:18 +00003287- optparse now optionally imports gettext. This allows its use in setup.py.
3288
Raymond Hettinger3489cad2004-12-05 05:20:42 +00003289- the pickle module no longer uses the deprecated bin parameter.
3290
Raymond Hettinger1bc82f82004-12-05 03:58:17 +00003291- the shelve module no longer uses the deprecated binary parameter.
3292
Raymond Hettinger6c92d762004-12-05 03:28:00 +00003293- the pstats module no longer uses the deprecated ignore() method.
3294
Raymond Hettingerf3fa9462004-12-05 01:58:09 +00003295- the filecmp module no longer uses the deprecated use_statcache argument.
3296
Raymond Hettinger664347b2004-12-04 21:21:53 +00003297- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
3298 extended or overridden by subclasses. Formerly, the subclassed method would
3299 be ignored by the rest of the module. (Bug #1078905).
3300
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003301- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
Raymond Hettinger3b0c7c22004-12-03 08:30:39 +00003302 the same meaning as in list.sort().
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003303
Walter Dörwald36733692004-12-22 12:50:50 +00003304- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
3305 once when a size argument is given. This prevents a buffer overflow in the
3306 tokenizer with very long source lines.
3307
Barry Warsaw538561e2006-01-01 21:48:54 +00003308- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
3309 immediately after creating the object, without any intervening
3310 ``.decompress()`` calls.
Andrew M. Kuchling3b585b32004-12-28 20:10:48 +00003311
Skip Montanaro05885812005-01-16 20:48:27 +00003312- The reconvert.quote function can now emit triple-quoted strings. The
3313 reconvert module now has some simple documentation.
Raymond Hettinger4901a1f2004-12-02 08:59:14 +00003314
Walter Dörwaldaf3b39a2005-02-18 13:22:43 +00003315- ``UserString.MutableString`` now supports negative indices in
3316 ``__setitem__`` and ``__delitem__``
3317
Greg Ward40407942005-03-05 02:53:17 +00003318- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
3319 correctly.
3320
Walter Dörwaldbc8e6422005-04-21 21:32:03 +00003321- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
3322 ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
3323 character even if the user has passed a size parameter to get a proper
3324 line ending. Remove the special handling of a "\r\n" that has been split
3325 between two lines.
3326
Walter Dörwalda47d1c02005-08-30 10:23:14 +00003327- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
3328 about illegal code points. The codec now supports PEP 293 style error
3329 handlers.
3330
Walter Dörwald78a78b02005-09-01 12:04:29 +00003331- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
Walter Dörwaldc5238b82005-09-01 11:56:53 +00003332 from the input stream, so that the output is a byte string in the correct
3333 encoding instead of a unicode string.
Greg Ward40407942005-03-05 02:53:17 +00003334
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003335- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
3336 considering it exactly like a '*'.
3337
Walter Dörwald007f8df2005-10-09 19:42:27 +00003338- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
3339 ``encodings.aliases``.
Gustavo Niemeyer6fa0c5a2005-09-14 08:54:39 +00003340
Walter Dörwald09f0dd52005-11-21 19:10:07 +00003341- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
3342
Gustavo Niemeyer548148812006-01-31 18:34:13 +00003343- Patch #1413711: Certain patterns of differences were making difflib
3344 touch the recursion limit.
3345
Walter Dörwald58917a62006-03-31 15:26:22 +00003346- Bug #947906: An object oriented interface has been added to the calendar
3347 module. It's possible to generate HTML calendar now and the module can be
Walter Dörwald48d5e502006-04-01 07:57:00 +00003348 called as a script (e.g. via ``python -mcalendar``). Localized month and
3349 weekday names can be ouput (even if an exotic encoding is used) using
3350 special classes that use unicode.
Walter Dörwald58917a62006-03-31 15:26:22 +00003351

Martin v. Löwis64c33dd2006-01-03 07:42:14 +00003366- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
3367 The zlib module is now builtin on Windows.
3368
Martin v. Löwisd5845ec2005-12-30 12:31:38 +00003369- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
3370
Martin v. Löwis147fbe52005-08-07 21:09:30 +00003371- Bug #1189330: configure did not correctly determine the necessary
3372 value of LINKCC if python was built with GCC 4.0.
3373
Trent Mick8321b422005-07-26 02:29:21 +00003374- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
3375 vulnerability in zlib 1.2.1 and 1.2.2.
3376
Brett Cannon08cd5982005-04-24 22:26:38 +00003377- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
3378 flags that change binary compatibility. Changes were also made to
3379 distutils.sysconfig to also use the environment variable when used during
Martin v. Löwisd7c795e2005-04-25 07:14:03 +00003380 compilation of the interpreter and of C extensions through distutils.
Brett Cannon08cd5982005-04-24 22:26:38 +00003381
Bob Ippolitoed233462005-03-29 13:47:59 +00003382- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
3383 and linking has changed (prebinding is now deprecated, and libcc_dynamic
3384 no longer exists). This configure patch makes things right.
3385
Martin v. Löwise2713be2005-03-08 15:03:08 +00003386- Bug #1158607: Build with --disable-unicode again.
3387
Brett Cannon46d96232005-02-16 00:07:19 +00003388- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
3389 defined. Discovered as a result of not being able to build on OS X.
3390
Brett Cannon516592f2004-12-07 00:42:59 +00003391- setup.py now uses the directories specified in LDFLAGS using the -L option
3392 and in CPPFLAGS using the -I option for adding library and include
3393 directories, respectively, for compiling extension modules against. This has
3394 led to the core being compiled using the values in CPPFLAGS. It also removes
3395 the need for the special-casing of both DarwinPorts and Fink for darwin since
3396 the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
3397 ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
3398 Fink, ``-I/opt/local/include`` for DarwinPorts).

Brett Cannon43802422005-02-10 20:48:03 +00003400- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
3401 to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
3402 Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
3403 Closes bug #1096244. Thanks Gregory Bond.

3407
Tim Petersc9d78aa2006-03-26 23:27:58 +00003408- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
3409 ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
3410 is obtained via the ``PyObject_`` family, it must be released via the
3411 ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
3412 always been officially true, but when Python's small-object allocator was
3413 introduced, an attempt was made to cater to a few extension modules
3414 discovered at the time that obtained memory via ``PyObject_New`` but
3415 released it via ``PyMem_DEL``. It's years later, and if such code still
3416 exists it will fail now (probably with segfaults, but calling wrong
3417 low-level memory management functions can yield many symptoms).

Raymond Hettingerbeb31012005-08-16 03:47:52 +00003419- Added a C API for set and frozenset objects.

Walter Dörwaldd1c1e102005-10-06 20:29:57 +00003423- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
3424 mapping argument now. This string is used as a mapping table. Byte values
3425 greater than the length of the string and 0xFFFE are treated as undefined
3426 mappings.
