16 processing: any non-float non-integer argument is now converted to

Mark Dickinson1cdfa5f2010-05-04 14:30:32 +000061- Issue #8567: Fix precedence of signals in Decimal module: when a
62 Decimal operation raises multiple signals and more than one of those
63 signals is trapped, the specification determines the order in which
64 the signals should be handled. In many cases this order wasn't
65 being followed, leading to the wrong Python exception being raised.

99 where the method could block indefinitely if called just before the
100 event loop started running. This also fixes the occasional freezes
101 witnessed in test_httpservers.
102
Antoine Pitrouc689d962010-04-24 20:13:37 +0000103- Issue #5103: SSL handshake would ignore the socket timeout and block

116 a non-infinite timeout. Also make that method friendlier with applications
117 wanting to continue using the socket in clear-text mode, by disabling
118 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
119
Antoine Pitrou878602a2010-04-21 19:41:28 +0000120- Issue #8484: Load all ciphers and digest algorithms when initializing

1019
Benjamin Petersonc6e80eb2008-12-21 17:01:26 +00001020- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

Vinay Sajip6badbe92009-01-20 22:49:13 +00001027- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Georg Brandld2094602008-12-05 08:51:30 +00001028 method on file objects with closefd=False. The file descriptor is still
1029 kept open but the file object behaves like a closed file. The ``FileIO``
1030 object also got a new readonly attribute ``closefd``.
1031
Georg Brandlfa71a902008-12-05 09:08:28 +00001032- Issue #3689: The list reversed iterator now supports __length_hint__

Jesse Nollerb48cfa62009-03-30 16:19:10 +00001100 socket.SO_REUSEADDR on all connections so that the user no longer needs
1101 to wait 120 seconds for the socket to expire.
1102
1103- Adjusted _tkinter to compile without warnings when WITH_THREAD is not

1403What's New in Python 2.6.1
1404==========================
1405
1406*Release date: 04-Dec-2008*
1407
1408Core and Builtins
1409-----------------
1410
1411- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1412 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1413 instead of throwing a MemoryError.
1414
1415- Issue #4367: Python would segfault during compiling when the unicodedata
1416 module couldn't be imported and \N escapes were present.
1417
1418- Issue #4348: Some bytearray methods returned that didn't cause any change to
1419 the bytearray, returned the same bytearray instead of a copy.
1420
1421- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1422
1423- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1424
1425- Issue #4048: The parser module now correctly validates relative imports.
1426
1427- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

1431 method does not return iterators for the 4th and 5th items.
1432
1433- Issue #4209: Enabling unicode_literals and the print_function in the same
1434 __future__ import didn't work.
1435
1436- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1437 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1438 really executed because I cannot move to such directory on win2k)
1439
1440- Issue #4069: When set.remove(element) is used with a set element, the element
1441 is temporarily replaced with an equivalent frozenset. But the eventual
1442 KeyError would always report the empty frozenset([]) as the missing key. Now
1443 it correctly refers to the initial element.
1444
1445- Fixed C99 style comments in several files. Python is now C89 compatible
1446 again.

1590Core and Builtins
1591-----------------
1592
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001593- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1594
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001595- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1596 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1597 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1598 ``printf`` function, whereas PyString_FromFormat has an independent
1599 implementation and uses "%zd" on all platforms for size_t values.
1600 This makes a difference on win64, where ``printf`` needs "%Id" to display
1601 64bit values.
1602
Benjamin Peterson97179b02008-09-09 20:55:01 +00001603- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1604 error.
1605
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001606- Issue #3777: long() applied to a float object now always return a long
1607 object; previously an int would be returned for small values. the __long__
1608 method is allowed to return either an int or a long, but the behaviour of
1609 float objects should not change to respect backward compatibility.
1610
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001611- Issue #3751: str.rpartition would perform a left-partition when called with
1612 a unicode argument.
1613
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001614- Issue #3683: Fix compilation when --without-threads is given.
1615
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001616- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001617 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001618 was correctly parsed but parsing of subsequent arguments failed.
1619
Vinay Sajip35e3b032008-09-01 14:33:59 +00001620- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001621 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1622 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1623 when given a tuple of classes as second argument, were looking up
1624 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1625 type object.
1626
Neal Norwitz18aa3882008-08-24 05:04:52 +00001627- Fix crashes on memory allocation failure found with failmalloc.
1628
1629- Fix memory leaks found with valgrind and update suppressions file.
1630
1631- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1632
1633- Fix problem using wrong name in decimal module reported by pychecker.
1634
Christian Heimes7d4c3172008-08-22 19:47:25 +00001635- Silenced another compiler warning about a used but not defined
1636 function 'stringlib_contains_obj'.
1637
Benjamin Peterson712ee922008-08-24 18:10:20 +00001638- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
1639 ``__delslice__``.
1640
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00001641- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
1642 library targets in the Makefile.
1643
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001644- Issue #1204: The configure script now tests for additional libraries
1645 that may be required when linking against readline. This fixes issues
1646 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
1647

Amaury Forgeot d'Arc24cb3822008-09-11 20:56:13 +00001656- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
1657 stack usage in the case of deeply nested objects.
1658

Nick Coghland2e09382008-09-11 12:11:06 +00001663- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
1664 silent misbehaviour when a single instance is nested in multiple
1665 with statements, or when the methods are invoked in the wrong order.
1666
Vinay Sajip844f7412008-09-09 13:42:08 +00001667- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.
1668
Nick Coghland2e09382008-09-11 12:11:06 +00001669- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001670 return a list or None rather than a custom object.
1671
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00001672- Issue #1638033: Cookie.Morsel gained the httponly attribute.

1679 its symbolic link.
1680
Vinay Sajip65d66e12008-09-04 07:31:21 +00001681- Issue #3772: Fixed regression problem in StreamHandler.emit().

1696 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1697 for catch_warnings() also led to an improvement in the raising of a
1698 DeprecationWarning related to warnings.warn_explicit().
1699
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001700- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001761What's New in Python 2.6 beta 3?
1762================================
1763
Barry Warsaw07a4a382008-08-21 01:15:08 +00001764*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001765
1766Core and Builtins
1767-----------------
1768
Guido van Rossumf8402962008-08-20 15:01:50 +00001769- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1770 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1771 extensions do not automatically benefit from the class attribute
1772 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1773 to their tp_flags field if they care. This is a backwards
1774 compatibility feature; in 3.0, all types will use the cache by
1775 default.
1776
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001777- Keyword arguments can now follow starred arguments. (``f(a, *args,
1778 keyword=23)`` is now valid syntax.)
1779
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001780- ctypes function pointers that are COM methods have a boolean True
1781 value again.
1782
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001783- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1784 by denying s# to parse objects that have a releasebuffer procedure,
1785 and introducing s*.
1786
Georg Brandl1e13ea92008-08-11 09:07:59 +00001787- Issue #3537: Fix an assertion failure when an empty but presized dict
1788 object was stored in the freelist.
1789
Mark Dickinsonb6467572008-08-04 21:30:09 +00001790- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1791 ValueError consistently across platforms.
1792
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001793- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1794 (64bit Unix, for example), unichr() would truncate its argument and return
1795 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1796
Neal Norwitze7d8be82008-07-31 17:17:14 +00001797- Apply security patches from Apple.
1798
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001799- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1800 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1801
Antoine Pitrou92f82162008-07-25 22:22:08 +00001802- Issue #1819: function calls with several named parameters are now on
1803 average 35% faster (as measured by pybench).
1804
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001805- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1806 the python debugger steps into a class statement: the free variables (local
1807 variables defined in an outer scope) would be deleted from the outer scope.
1808
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001809- Issue #2620: Overflow checking when allocating or reallocating memory
1810 was not always being done properly in some python types and extension
1811 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1812 all been updated to perform better checks and places in the code that
1813 would previously leak memory on the error path when such an allocation
1814 failed have been fixed.
1815
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001816Library
1817-------
1818
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001819- Issue #3612: Added some missing basic types in ctypes.wintypes.
1820
Benjamin Petersone977ad42008-08-20 01:42:01 +00001821- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1822 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1823
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001824- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1825 version reported by these tools does not necessarily follow the python
1826 version numbering scheme, so the module is less strict when parsing it.
1827
Nick Coghlanf70385a2008-08-18 12:42:46 +00001828- Issue #2235: Added Py3k warnings for types which will become unhashable
1829 under the stricter __hash__ inheritance rules in 3.0. Several types
1830 which did not meet the rules for hash invariants and were already
1831 unhashable in 3.0 have now been explicitly flagged as unhashable in
1832 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1833 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1834
Brett Cannon88f801d2008-08-18 00:46:22 +00001835- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1836 imported into the module but exposed as part of the module's API.
1837
Brett Cannon7b96f072008-08-18 00:41:11 +00001838- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1839
Brett Cannon46225e72008-08-18 00:36:52 +00001840- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001842- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1843
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001844- Issue #3575: Incremental decoder's decode function now takes bytearray
1845 by using 's*' instead of 't#'.
1846
Jesus Cea585ad8a2009-07-02 15:37:21 +00001847- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001848 fails unicode conversion on 2nd parameter. (windows only)
1849
Facundo Batista94f243a2008-08-17 03:38:39 +00001850- Issue 2464. urllib2 now supports a malformation in the URL received
1851 in a redirect.
1852
Brett Cannonabe423e2008-08-16 21:47:07 +00001853- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001854 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001855
Facundo Batistaeb90b782008-08-16 14:44:07 +00001856- Issue #2776: fixed small issue when handling an URL with double slash
1857 after a 302 response in the case of not going through a proxy.
1858
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001859- Issue #2676: in the email package, content-type parsing was hanging on
1860 pathological input because of quadratic or exponential behaviour of a
1861 regular expression.
1862
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001863- Issue #3476: binary buffered reading through the new "io" library is now
1864 thread-safe.
1865
Brett Cannonbf3157b2008-08-14 05:00:03 +00001866- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1867 since mimetools itself is deprecated. Because modules are cached, all
1868 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1869
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001870- Issue #3134: shutil referenced undefined WindowsError symbol.
1871
Robert Schuppenies14646332008-08-10 11:01:53 +00001872- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1873 menu entries were not deleted.
1874
Brett Cannon83e81842008-08-09 23:30:55 +00001875- Copied the implementation of reduce() to _functools.reduce() to have a
1876 version that did not raise a DeprecationWarning under -3.

Antoine Pitroude781a42008-08-09 12:43:23 +00001904 asking for a specific length. This problem only affected files opened

1961-----------------
1962
Georg Brandl3e483f62008-07-16 22:57:41 +00001963- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1964 its methods now allow for items objects that can be converted to
1965 an integer using operator.index().
1966
Mark Dickinson64b7e502008-07-16 09:40:03 +00001967- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1968 produced a ValueError instead of giving the correct float.
1969
Eric Smitha5fa5a22008-07-16 00:11:49 +00001970- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1971 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1972
Mark Dickinson7103aa42008-07-15 19:08:33 +00001973- Issue #3008: the float type has a new instance method 'float.hex'
1974 and a new class method 'float.fromhex' to convert floating-point
1975 numbers to and from hexadecimal strings, respectively.
1976
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001977- Issue #2235: __hash__ is once again inherited by default. To allow
1978 collections.Hashable to remain meaningful in the presence of the
1979 default hash implementation (object.__hash__), it is now possible
1980 to explicit block inheritance of hash by setting __hash__=None at
1981 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1982 level.
1983
Nick Coghlanb028f502008-07-13 14:52:36 +00001984- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1985 the parent module cannot be found while performing an absolute import.
1986 This means that an incorrectly defined __package__ attribute will
1987 now only prevent relative imports in that module rather than causing
1988 all imports from that module to fail.
1989
Nick Coghlan14ff9942008-07-08 14:21:42 +00001990- Issue #2517: Allow unicode messages in Exceptions again by correctly

2000 another thread's dictionary.
2001
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002002- Issue #3004: Minor change to slice.indices(): the start and stop
2003 arguments are now treated identically, making the behaviour easier
2004 to describe and understand. For example, slice(None, -10,
2005 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2006 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2007 10, -1).
2008
Georg Brandl278fc502008-07-19 12:46:12 +00002009- Issue #3219: Calling a function with repeated keyword arguments,
2010 f(a=2, a=23), would not cause a syntax error. This was a regression
2011 from 2.4 caused by the switch to the new compiler.

2023
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002024- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002049- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2050 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002051 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002052 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002068- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

2456
Brett Cannonb61d8012008-05-11 23:39:04 +00002457- ``Lib/lib-old`` is now added to sys.path.
2458
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002459- On MacOS X it is now possible to install the framework in 64-bit
2460 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002461 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002462
2463 This is controlled by the configure argument ``--with-universal-archs``:
2464
2465 - ``--with-universal-archs=all``: install 4-way universal
2466
2467 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2468
2469 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2470
2471 This option should be used in combination with ``--enable-universalsdk=``.
2472
2473 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Christian Heimes7a990612008-05-26 13:15:11 +00002482
2483- The PyString functions have been renamed to PyBytes. A batch of
2484 defines were added so that the linker still sees the original
2485 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002523- Issue #1631171: Re-implement the 'warnings' module in C (the
2524 original Python code has been kept as backup). This will allow for
2525 using the 'warning's machinery in such places as the parser where
2526 use of pure Python code is not possible. Both the ``showarning()``
2527 and ``formatwarning()`` gain an optional 'line' argument which is
2528 not called by default for backwards-compatibility reasons. Setting
2529 ``warnings.showwarning()`` to an implementation that lacks support
2530 for the ``line`` argument will raise a DeprecationWarning.

2554
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002555- The getpass module has been improved on Unix. It now uses /dev/tty
2556 by default and uses stderr instead of stdout. A GetPassWarning is
2557 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00002558

2569 implementation detail of the public ``types`` module, has been
2570 removed and replaced by pure python code.
Amaury Forgeot d'Arc02f33b42008-04-08 23:10:07 +00002571
Georg Brandl3ee81df2008-05-17 18:14:43 +00002572- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002573 extension modules between 32 and 64 bit platforms. See the distutls
2574 build documentation for more information.

2577 threads at once without fear of crashing the Python interpreter. If
2578 file.close() is called while an object is in use by another thread
2579 an IOError exception will be raised and the file will not be closed.
2580
Thomas Hellerf7906482008-04-04 19:43:25 +00002581- The bundled libffi copy is now in sync with the recently released

2586 so the controlled environment will more closely mirror the typical
2587 script environment. This supports setup.py scripts that refer to
2588 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002593- Issue #2550: The approach used by client/server code for obtaining
2594 ports to listen on in network-oriented tests has been refined in an
2595 effort to facilitate running multiple instances of the entire
2596 regression test suite in parallel without issue.
2597 test_support.bind_port() has been fixed such that it will always
2598 return a unique port -- which wasn't always the case with the
2599 previous implementation, especially if socket options had been set
2600 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2601 new implementation of bind_port() will actually raise an exception
2602 if it is passed an AF_INET/SOCK_STREAM socket with either the
2603 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2604 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2605 the socket it's been passed. This currently only applies to
2606 Windows. This option prevents any other sockets from binding to the
2607 host/port we've bound to, thus removing the possibility of the
2608 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2609 when a second SOCK_STREAM socket binds and accepts to a host/port
2610 that's already been bound by another socket. The optional preferred
2611 port parameter to bind_port() has been removed. Under no
2612 circumstances should tests be hard coding ports!
2613
2614 test_support.find_unused_port() has also been introduced, which will
2615 pass a temporary socket object to bind_port() in order to obtain an
2616 unused port. The temporary socket object is then closed and
2617 deleted, and the port is returned. This method should only be used
2618 for obtaining an unused port in order to pass to an external program
2619 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2620 a parameter to a server-oriented class that doesn't give you direct
2621 access to the underlying socket used.
2622
2623 Finally, test_support.HOST has been introduced, which should be used
2624 for the host argument of any relevant socket calls (i.e. bind and
2625 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002626
2627 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002628 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002629 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2630 test_asynchat and test_socket_ssl.
2631
Georg Brandl3ee81df2008-05-17 18:14:43 +00002632 It is now possible for multiple instances of the regression test
2633 suite to run in parallel without issue.

2900-----------------
2901
Fred Drakea8ee94b2008-03-01 02:45:07 +00002902- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002903 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002904
Georg Brandlad61bc82008-02-23 15:11:18 +00002905- Issue #2067: file.__exit__() now calls subclasses' close() method.
2906
2907- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002908
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002909- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002910 issue 215555 for a discussion.
2911
Eric Smitha73fbe72008-02-23 03:09:44 +00002912- Added the future_builtins module, which contains hex() and oct().
2913 These are the PEP 3127 version of these functions, designed to be
2914 compatible with the hex() and oct() builtins from Python 3.0. They
2915 differ slightly in their output formats from the existing, unchanged
2916 Python 2.6 builtins. The expected usage of the future_builtins
2917 module is:
2918 from future_builtins import hex, oct
2919
Eric Smith7ef40bf2008-02-20 23:34:22 +00002920- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2921 exponents for exponents with absolute value < 100. Follows C99
2922 standard. This is a change on Windows, which would use 3 digits.
2923 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2924 so that any alterations it does to the resulting string will be
2925 available in stringlib/formatter.h (for float.__format__).
2926
Eric Smith5a3c1352008-02-19 13:21:56 +00002927- Implemented PEP 3101, Advanced String Formatting. This adds a new
2928 builtin format(); a format() method for str and unicode; a
2929 __format__() method to object, str, unicode, int, long, float, and
2930 datetime; the class string.Formatter; and the C API
2931 PyObject_Format().
2932
Georg Brandl3ee81df2008-05-17 18:14:43 +00002933- Fixed several potential crashes, all caused by specially crafted
2934 __del__ methods exploiting objects in temporarily inconsistent
2935 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002936
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002937- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002938 prevent a possible crash: an Abstract Base Class would try to access
2939 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002940

Georg Brandl3ee81df2008-05-17 18:14:43 +00002944- Clear all free lists during a gc.collect() of the highest generation
2945 in order to allow pymalloc to free more arenas. Python may give back
2946 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002947
Georg Brandl3ee81df2008-05-17 18:14:43 +00002948- Issue #2045: Fix an infinite recursion triggered when printing a
2949 subclass of collections.defaultdict, if its default_factory is set
2950 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002951
Christian Heimesf75dbef2008-02-08 00:11:31 +00002952- Fixed a minor memory leak in dictobject.c. The content of the free
2953 list was not freed on interpreter shutdown.
2954
Georg Brandl5a7eca12010-03-21 19:29:04 +00002955- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00002956 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002957
Georg Brandl3ee81df2008-05-17 18:14:43 +00002958- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2959 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002960 to compact the internal free lists of pre-allocted ints and floats.
2961
Georg Brandl3ee81df2008-05-17 18:14:43 +00002962- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2963 calls. Python expected the return type int but the fork familie
2964 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002965
Georg Brandl3ee81df2008-05-17 18:14:43 +00002966- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2967 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002968
Georg Brandl3ee81df2008-05-17 18:14:43 +00002969- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2970 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002971
Georg Brandl3ee81df2008-05-17 18:14:43 +00002972- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2973 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00002975- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2976 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002977
Georg Brandl3ee81df2008-05-17 18:14:43 +00002978- Patch #1473257: generator objects gain a gi_code attribute. This is
2979 the same object as the func_code attribute of the function that
2980 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002981
Georg Brandl3ee81df2008-05-17 18:14:43 +00002982- Issue #1920: "while 0" statements were completely removed by the
2983 compiler, even in the presence of an "else" clause, which is
2984 supposed to be run when the condition is false. Now the compiler
2985 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002986
Guido van Rossumeead05f2008-01-24 18:21:02 +00002987- A few crashers fixed: weakref_in_del.py (issue #1377858);
2988 loosing_dict_ref.py (issue #1303614, test67.py);
2989 borrowed_ref_[34].py (not in tracker).
2990
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002991- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002992 suppressed while an extension is loaded by calling SetErrorMode in
2993 dynload_win.c. The error is still reported properly.
2994
Georg Brandl3ee81df2008-05-17 18:14:43 +00002995- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002996 several extension methods and modules do not work without unicode
2997 support.
2998
Georg Brandl26543b12008-01-21 18:36:51 +00002999- Issue #1882: when compiling code from a string, encoding cookies in the
3000 second line of code were not always recognized correctly.
3001
Georg Brandl14404b62008-01-19 19:27:05 +00003002- Issue #1679: "0x" was taken as a valid integer literal.
3003
Georg Brandl6caad7d2008-01-26 14:19:22 +00003004- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003005 added.
3006
Christian Heimesc94e2b52008-01-14 04:13:37 +00003007- sys.float_info / PyFloat_GetInfo: The floating point information
3008 object was converted from a dict to a specialized structseq object.
3009
Georg Brandl3ee81df2008-05-17 18:14:43 +00003010- Patch #1816: Added sys.flags structseq. It exposes the status of
3011 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003012
Georg Brandl3ee81df2008-05-17 18:14:43 +00003013- Objects/structseq.c: Implemented new structseq representation. The
3014 patch makes structseqs (e.g. the return value of os.stat) more
3015 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003016
Georg Brandl3ee81df2008-05-17 18:14:43 +00003017- Patch #1700288: added a type attribute cache that caches method
3018 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003019
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003020- Bug #1776: __import__() no longer accepts filenames on any platform.
3021 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003022
Georg Brandlaed6c662008-01-07 17:25:53 +00003023- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3024
Georg Brandl3ee81df2008-05-17 18:14:43 +00003025- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3026 envvar and sys.dont_write_bytecode attribute. All these can be set
3027 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003028
Georg Brandl3ee81df2008-05-17 18:14:43 +00003029- Improve some exception messages when Windows fails to load an
3030 extension module. Now we get for example '%1 is not a valid Win32
3031 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003032

Christian Heimes0a8143f2007-12-18 23:22:54 +00003038- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003039 and INF. float("nan"), float("inf") and float("-inf") now work on
3040 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003041
Georg Brandl3ee81df2008-05-17 18:14:43 +00003042- Compiler now generates simpler and faster code for dictionary
3043 literals. The oparg for BUILD_MAP now indicates an estimated
3044 dictionary size. There is a new opcode, STORE_MAP, for adding
3045 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003074- Patch #1739468: Directories and zipfiles containing a __main__.py
3075 file can now be directly executed by passing their name to the
3076 interpreter. The directory/zipfile is automatically inserted as the
3077 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003079- Issue #1265: Fix a problem with sys.settrace, if the tracing
3080 function uses a generator expression when at the same time the
3081 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003082
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003083- sets and frozensets now have an isdisjoint() method.
3084
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003085- optimize the performance of builtin.sum().
3086
Neal Norwitz44f326e2007-10-05 05:29:17 +00003087- Fix warnings found by the new version of the Coverity checker.
3088
Georg Brandl5a7eca12010-03-21 19:29:04 +00003089- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003090 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3091 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003092
Georg Brandl3ee81df2008-05-17 18:14:43 +00003093- Issue #1686386: Tuple's tp_repr did not take into account the
3094 possibility of having a self-referential tuple, which is possible
3095 from C code. Nor did object's tp_str consider that a type's tp_str
3096 could do something that could lead to an inifinite recursion.
3097 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3098 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003099
Georg Brandl3ee81df2008-05-17 18:14:43 +00003100- Issue #1164: It was possible to trigger deadlock when using the
3101 'print' statement to write to a file since the GIL was not released
3102 as needed. Now PyObject_Print() does the right thing along with
3103 various tp_print implementations of the built-in types and those in
3104 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003105
Georg Brandl3ee81df2008-05-17 18:14:43 +00003106- Issue #1147: Exceptions were directly allowing string exceptions in
3107 their throw() method even though string exceptions no longer
3108 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003109
Georg Brandl3ee81df2008-05-17 18:14:43 +00003110- Issue #1096: Prevent a segfault from getting the repr of a very
3111 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003112
Brett Cannon1e534b52007-09-07 04:18:30 +00003113- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003114 PyObject_Call() never calling back out to Python code to trigger
3115 recursion depth updates/checks. Required the creation of a static
3116 RuntimeError instance in case normalizing an exception put the
3117 recursion check value past its limit. Fixes crashers
3118 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003119
Georg Brandl3ee81df2008-05-17 18:14:43 +00003120- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003133- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003134 __*__ attributes. (Some already existed, e.g., __doc__ and
3135 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003136
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003137- Add -3 option to the interpreter to warn about features that are
3138 deprecated and will be changed/removed in Python 3.0.
3139
Georg Brandl2134e752007-05-21 20:34:16 +00003140- Patch #1686487: you can now pass any mapping after '**' in function
3141 calls.
3142
Collin Winter62903052007-05-18 23:11:24 +00003143- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003144 "except E as target:". This is to provide forwards compatibility
3145 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003146
Brett Cannon229cee22007-05-05 01:34:02 +00003147- Deprecate BaseException.message as per PEP 352.
3148
Georg Brandl3ee81df2008-05-17 18:14:43 +00003149- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003150 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003151
Vinay Sajip8549ce32007-05-06 17:53:37 +00003152- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003153 setting a plain string, ie don't expand to single letter identifiers.
3154
Raymond Hettinger13936692007-04-11 18:40:58 +00003155- Request #1191699: Slices can now be pickled.
3156
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003157- Request #1193128: str.translate() now allows a None argument for
3158 translations that only remove characters without re-mapping the
3159 remaining characters.
3160
Georg Brandl5cb76c12007-03-21 09:00:39 +00003161- Patch #1682205: a TypeError while unpacking an iterable is no longer
3162 masked by a generic one with the message "unpack non-sequence".
3163
Neal Norwitzaa754b72007-03-21 06:39:48 +00003164- Remove unused file Python/fmod.c.
3165
Guido van Rossum143b5642007-03-23 04:58:42 +00003166- Bug #1683368: The object.__init__() and object.__new__() methods are
3167 now stricter in rejecting excess arguments. The only time when
3168 either allows excess arguments is when it is not overridden and the
3169 other one is. For backwards compatibility, when both are
3170 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003171 warning later). Also, type.__init__() insists on the same signature
3172 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003173
Georg Brandl3ee81df2008-05-17 18:14:43 +00003174- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3175 object to complex using its __complex__() method before falling back
3176 to the __float__() method. Therefore, the functions in the cmath
3177 module now can operate on objects that define a __complex__()
3178 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003179
Georg Brandl3ee81df2008-05-17 18:14:43 +00003180- Patch #1623563: allow __class__ assignment for classes with
3181 __slots__. The old and the new class are still required to have the
3182 same slot names.

3188 ``object.__reduce_ex__()`` is called with an object that is faking
3189 its type.

3195
Georg Brandl7b9c5552007-03-12 14:30:05 +00003196- Bug #1678647: write a newline after printing an exception in any
3197 case, even when converting the value to a string failed.
3198
Georg Brandl871f1bc2007-03-12 13:17:36 +00003199- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003200 its argument, if it exists. If not, it will work like before. This
3201 allows customizing the output of dir() in the presence of a
3202 __getattr__().

Georg Brandl4e933132006-09-06 20:05:58 +00003317- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Guido van Rossum8bc09652008-02-21 18:18:37 +00003376- Removed uses of dict.has_key() from distutils, and uses of

Facundo Batistad918a652007-04-24 13:54:38 +00003725- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003726 the client's request was successfully received, understood, and

3737 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3738 work started with create_connection() and timeout in httplib, and

3740
Vinay Sajip8549ce32007-05-06 17:53:37 +00003741- Patch #1676823: Added create_connection() to socket.py, which may be

Georg Brandl3ee81df2008-05-17 18:14:43 +00003767 AttributeError instead of an IOError when the server's response
3768 didn't contain a valid HTTP status line.

3800
Georg Brandl92a6bae2007-03-13 17:43:32 +00003801- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003802 are set for invalid interpolation sequences that would lead to
3803 errors on reading back those values.

3859 TestCase and TestSuite subclasses (not instances) are no longer
3860 accepted in TestSuite.addTest(). This should cause no

3862 -- the failure just occurred later, with a more cumbersome
3863 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004252 time so that opening a database previously created with the DB_DUP
4253 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4254 opens. Specifically: dictionary assignment to a DB object will
4255 replace all values for a given key when the database allows
4256 duplicate values. DB users should use DB.put(k, v) when they want
4257 to store duplicates; not DB[k] = v.

4264 characters with ASCII value less than 32. Also, it correctly quotes
4265 dots only if they occur on a single line, as opposed to the previous
4266 behavior of quoting dots if they are the second character of any
4267 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004268
