Mark Dickinsone02c9d22010-05-07 13:23:18 +000015- Issue #1533: fix inconsistency in range function argument
16 processing: any non-float non-integer argument is now converted to
17 an integer (if possible) using its __int__ method. Previously, only
18 small arguments were treated this way; larger arguments (those whose
19 __int__ was outside the range of a C long) would produce a TypeError.

52 error messages when accessing undefined class attributes because of the cheap
53 inheritance with the underlying socket object.
54

63
Mark Dickinson1cdfa5f2010-05-04 14:30:32 +000064- Issue #8567: Fix precedence of signals in Decimal module: when a
65 Decimal operation raises multiple signals and more than one of those
66 signals is trapped, the specification determines the order in which
67 the signals should be handled. In many cases this order wasn't
68 being followed, leading to the wrong Python exception being raised.

Antoine Pitrou53d7d062010-04-25 21:55:45 +0000101- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
102 where the method could block indefinitely if called just before the
103 event loop started running. This also fixes the occasional freezes
104 witnessed in test_httpservers.
105
Antoine Pitrouc689d962010-04-24 20:13:37 +0000106- Issue #5103: SSL handshake would ignore the socket timeout and block

119 a non-infinite timeout. Also make that method friendlier with applications
120 wanting to continue using the socket in clear-text mode, by disabling
121 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
122
Antoine Pitrou878602a2010-04-21 19:41:28 +0000123- Issue #8484: Load all ciphers and digest algorithms when initializing

1410What's New in Python 2.6.1
1411==========================
1412
1413*Release date: 04-Dec-2008*
1414
1415Core and Builtins
1416-----------------
1417
1418- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1419 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1420 instead of throwing a MemoryError.
1421
1422- Issue #4367: Python would segfault during compiling when the unicodedata
1423 module couldn't be imported and \N escapes were present.
1424
1425- Issue #4348: Some bytearray methods returned that didn't cause any change to
1426 the bytearray, returned the same bytearray instead of a copy.
1427
1428- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1429
1430- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1431
1432- Issue #4048: The parser module now correctly validates relative imports.
1433
1434- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1435 exec statement.
1436
1437- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1438 method does not return iterators for the 4th and 5th items.
1439
1440- Issue #4209: Enabling unicode_literals and the print_function in the same
1441 __future__ import didn't work.
1442
1443- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1444 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1445 really executed because I cannot move to such directory on win2k)
1446
1447- Issue #4069: When set.remove(element) is used with a set element, the element
1448 is temporarily replaced with an equivalent frozenset. But the eventual
1449 KeyError would always report the empty frozenset([]) as the missing key. Now
1450 it correctly refers to the initial element.
1451
1452- Fixed C99 style comments in several files. Python is now C89 compatible
1453 again.

1598-----------------
1599
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001600- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1601
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001602- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1603 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1604 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1605 ``printf`` function, whereas PyString_FromFormat has an independent
1606 implementation and uses "%zd" on all platforms for size_t values.
1607 This makes a difference on win64, where ``printf`` needs "%Id" to display
1608 64bit values.
1609
Benjamin Peterson97179b02008-09-09 20:55:01 +00001610- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1611 error.
1612
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001613- Issue #3777: long() applied to a float object now always return a long
1614 object; previously an int would be returned for small values. the __long__
1615 method is allowed to return either an int or a long, but the behaviour of
1616 float objects should not change to respect backward compatibility.
1617
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001618- Issue #3751: str.rpartition would perform a left-partition when called with
1619 a unicode argument.
1620
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001621- Issue #3683: Fix compilation when --without-threads is given.
1622
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001623- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001624 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001625 was correctly parsed but parsing of subsequent arguments failed.
1626
Vinay Sajip35e3b032008-09-01 14:33:59 +00001627- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001628 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1629 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1630 when given a tuple of classes as second argument, were looking up
1631 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1632 type object.
1633
Neal Norwitz18aa3882008-08-24 05:04:52 +00001634- Fix crashes on memory allocation failure found with failmalloc.
1635
1636- Fix memory leaks found with valgrind and update suppressions file.
1637
1638- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1639
1640- Fix problem using wrong name in decimal module reported by pychecker.
1641
Christian Heimes7d4c3172008-08-22 19:47:25 +00001642- Silenced another compiler warning about a used but not defined
1643 function 'stringlib_contains_obj'.
1644
Benjamin Peterson712ee922008-08-24 18:10:20 +00001645- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
1646 ``__delslice__``.
1647
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00001648- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
1649 library targets in the Makefile.
1650
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001651- Issue #1204: The configure script now tests for additional libraries
1652 that may be required when linking against readline. This fixes issues
1653 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
1654

Nick Coghland2e09382008-09-11 12:11:06 +00001670- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
1671 silent misbehaviour when a single instance is nested in multiple
1672 with statements, or when the methods are invoked in the wrong order.
1673
Vinay Sajip844f7412008-09-09 13:42:08 +00001674- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.
1675
Nick Coghland2e09382008-09-11 12:11:06 +00001676- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001677 return a list or None rather than a custom object.
1678
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00001679- Issue #1638033: Cookie.Morsel gained the httponly attribute.

1703 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1704 for catch_warnings() also led to an improvement in the raising of a
1705 DeprecationWarning related to warnings.warn_explicit().
1706
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001707- The deprecation warnings for the old camelCase threading API were removed.

Benjamin Peterson37346b22008-08-23 20:27:43 +00001724Extension Modules
1725-----------------
1726
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001727- Issue #2975: When compiling several extension modules with Visual Studio 2008

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001768What's New in Python 2.6 beta 3?
1769================================
1770
Barry Warsaw07a4a382008-08-21 01:15:08 +00001771*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001772
1773Core and Builtins
1774-----------------
1775
Guido van Rossumf8402962008-08-20 15:01:50 +00001776- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1777 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1778 extensions do not automatically benefit from the class attribute
1779 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1780 to their tp_flags field if they care. This is a backwards
1781 compatibility feature; in 3.0, all types will use the cache by
1782 default.
1783
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001784- Keyword arguments can now follow starred arguments. (``f(a, *args,
1785 keyword=23)`` is now valid syntax.)
1786
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001787- ctypes function pointers that are COM methods have a boolean True
1788 value again.
1789
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001790- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1791 by denying s# to parse objects that have a releasebuffer procedure,
1792 and introducing s*.
1793
Georg Brandl1e13ea92008-08-11 09:07:59 +00001794- Issue #3537: Fix an assertion failure when an empty but presized dict
1795 object was stored in the freelist.
1796
Mark Dickinsonb6467572008-08-04 21:30:09 +00001797- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1798 ValueError consistently across platforms.
1799
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001800- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1801 (64bit Unix, for example), unichr() would truncate its argument and return
1802 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1803
Neal Norwitze7d8be82008-07-31 17:17:14 +00001804- Apply security patches from Apple.
1805
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001806- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1807 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1808
Antoine Pitrou92f82162008-07-25 22:22:08 +00001809- Issue #1819: function calls with several named parameters are now on
1810 average 35% faster (as measured by pybench).
1811
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001812- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1813 the python debugger steps into a class statement: the free variables (local
1814 variables defined in an outer scope) would be deleted from the outer scope.
1815
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001816- Issue #2620: Overflow checking when allocating or reallocating memory
1817 was not always being done properly in some python types and extension
1818 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1819 all been updated to perform better checks and places in the code that
1820 would previously leak memory on the error path when such an allocation
1821 failed have been fixed.
1822
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001823Library
1824-------
1825
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001826- Issue #3612: Added some missing basic types in ctypes.wintypes.
1827
Benjamin Petersone977ad42008-08-20 01:42:01 +00001828- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1829 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1830
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001831- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1832 version reported by these tools does not necessarily follow the python
1833 version numbering scheme, so the module is less strict when parsing it.
1834
Nick Coghlanf70385a2008-08-18 12:42:46 +00001835- Issue #2235: Added Py3k warnings for types which will become unhashable
1836 under the stricter __hash__ inheritance rules in 3.0. Several types
1837 which did not meet the rules for hash invariants and were already
1838 unhashable in 3.0 have now been explicitly flagged as unhashable in
1839 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1840 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1841
Brett Cannon88f801d2008-08-18 00:46:22 +00001842- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1843 imported into the module but exposed as part of the module's API.
1844
Brett Cannon7b96f072008-08-18 00:41:11 +00001845- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1846
Brett Cannon46225e72008-08-18 00:36:52 +00001847- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001849- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1850
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001851- Issue #3575: Incremental decoder's decode function now takes bytearray
1852 by using 's*' instead of 't#'.
1853
Jesus Cea585ad8a2009-07-02 15:37:21 +00001854- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001855 fails unicode conversion on 2nd parameter. (windows only)
1856
Facundo Batista94f243a2008-08-17 03:38:39 +00001857- Issue 2464. urllib2 now supports a malformation in the URL received
1858 in a redirect.
1859
Brett Cannonabe423e2008-08-16 21:47:07 +00001860- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001861 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001862
Facundo Batistaeb90b782008-08-16 14:44:07 +00001863- Issue #2776: fixed small issue when handling an URL with double slash
1864 after a 302 response in the case of not going through a proxy.
1865
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001866- Issue #2676: in the email package, content-type parsing was hanging on
1867 pathological input because of quadratic or exponential behaviour of a
1868 regular expression.
1869
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001870- Issue #3476: binary buffered reading through the new "io" library is now
1871 thread-safe.
1872
Brett Cannonbf3157b2008-08-14 05:00:03 +00001873- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1874 since mimetools itself is deprecated. Because modules are cached, all
1875 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1876
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001877- Issue #3134: shutil referenced undefined WindowsError symbol.
1878
Robert Schuppenies14646332008-08-10 11:01:53 +00001879- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to

Antoine Pitroude781a42008-08-09 12:43:23 +00001911 asking for a specific length. This problem only affected files opened

1969
Georg Brandl3e483f62008-07-16 22:57:41 +00001970- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1971 its methods now allow for items objects that can be converted to
1972 an integer using operator.index().
1973
Mark Dickinson64b7e502008-07-16 09:40:03 +00001974- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1975 produced a ValueError instead of giving the correct float.
1976
Eric Smitha5fa5a22008-07-16 00:11:49 +00001977- Issue #3083: Add alternate (#) formatting for bin, oct, hex output

1979
Mark Dickinson7103aa42008-07-15 19:08:33 +00001980- Issue #3008: the float type has a new instance method 'float.hex'
1981 and a new class method 'float.fromhex' to convert floating-point
1982 numbers to and from hexadecimal strings, respectively.
1983
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001984- Issue #2235: __hash__ is once again inherited by default. To allow
1985 collections.Hashable to remain meaningful in the presence of the
1986 default hash implementation (object.__hash__), it is now possible
1987 to explicit block inheritance of hash by setting __hash__=None at
1988 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1989 level.
1990
Nick Coghlanb028f502008-07-13 14:52:36 +00001991- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1992 the parent module cannot be found while performing an absolute import.
1993 This means that an incorrectly defined __package__ attribute will
1994 now only prevent relative imports in that module rather than causing
1995 all imports from that module to fail.
1996
Nick Coghlan14ff9942008-07-08 14:21:42 +00001997- Issue #2517: Allow unicode messages in Exceptions again by correctly

2007 another thread's dictionary.
2008
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002009- Issue #3004: Minor change to slice.indices(): the start and stop
2010 arguments are now treated identically, making the behaviour easier
2011 to describe and understand. For example, slice(None, -10,
2012 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2013 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2014 10, -1).
2015
Georg Brandl278fc502008-07-19 12:46:12 +00002016- Issue #3219: Calling a function with repeated keyword arguments,
2017 f(a=2, a=23), would not cause a syntax error. This was a regression
2018 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002056- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2057 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002058 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002059 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002075- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

2448 an extension. This was added for compatibility with Apple's build
2449 of Python.
2450
2451- The bundled OSX-specific copy of libbffi is now in sync with the version
2452 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
2453
Georg Brandl25c34082008-08-18 23:09:49 +00002454- The threading module gained aliases for names that will be removed in the
2455 3.x series.

2463
Brett Cannonb61d8012008-05-11 23:39:04 +00002464- ``Lib/lib-old`` is now added to sys.path.
2465
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002466- On MacOS X it is now possible to install the framework in 64-bit
2467 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002468 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002469
2470 This is controlled by the configure argument ``--with-universal-archs``:
2471
2472 - ``--with-universal-archs=all``: install 4-way universal
2473
2474 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2475
2476 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2477
2478 This option should be used in combination with ``--enable-universalsdk=``.
2479
2480 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 +00002489
2490- The PyString functions have been renamed to PyBytes. A batch of
2491 defines were added so that the linker still sees the original
2492 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002530- Issue #1631171: Re-implement the 'warnings' module in C (the
2531 original Python code has been kept as backup). This will allow for
2532 using the 'warning's machinery in such places as the parser where
2533 use of pure Python code is not possible. Both the ``showarning()``
2534 and ``formatwarning()`` gain an optional 'line' argument which is
2535 not called by default for backwards-compatibility reasons. Setting
2536 ``warnings.showwarning()`` to an implementation that lacks support
2537 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002562- The getpass module has been improved on Unix. It now uses /dev/tty
2563 by default and uses stderr instead of stdout. A GetPassWarning is
2564 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002579- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002580 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002600- Issue #2550: The approach used by client/server code for obtaining
2601 ports to listen on in network-oriented tests has been refined in an
2602 effort to facilitate running multiple instances of the entire
2603 regression test suite in parallel without issue.
2604 test_support.bind_port() has been fixed such that it will always
2605 return a unique port -- which wasn't always the case with the
2606 previous implementation, especially if socket options had been set
2607 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2608 new implementation of bind_port() will actually raise an exception
2609 if it is passed an AF_INET/SOCK_STREAM socket with either the
2610 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2611 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2612 the socket it's been passed. This currently only applies to
2613 Windows. This option prevents any other sockets from binding to the
2614 host/port we've bound to, thus removing the possibility of the
2615 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2616 when a second SOCK_STREAM socket binds and accepts to a host/port
2617 that's already been bound by another socket. The optional preferred
2618 port parameter to bind_port() has been removed. Under no
2619 circumstances should tests be hard coding ports!
2620
2621 test_support.find_unused_port() has also been introduced, which will
2622 pass a temporary socket object to bind_port() in order to obtain an
2623 unused port. The temporary socket object is then closed and
2624 deleted, and the port is returned. This method should only be used
2625 for obtaining an unused port in order to pass to an external program
2626 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2627 a parameter to a server-oriented class that doesn't give you direct
2628 access to the underlying socket used.
2629
2630 Finally, test_support.HOST has been introduced, which should be used
2631 for the host argument of any relevant socket calls (i.e. bind and
2632 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002633
2634 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002635 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002636 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2637 test_asynchat and test_socket_ssl.
2638
Georg Brandl3ee81df2008-05-17 18:14:43 +00002639 It is now possible for multiple instances of the regression test
2640 suite to run in parallel without issue.

2907-----------------
2908
Fred Drakea8ee94b2008-03-01 02:45:07 +00002909- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002910 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002911
Georg Brandlad61bc82008-02-23 15:11:18 +00002912- Issue #2067: file.__exit__() now calls subclasses' close() method.
2913
2914- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002915
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002916- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002917 issue 215555 for a discussion.
2918
Eric Smitha73fbe72008-02-23 03:09:44 +00002919- Added the future_builtins module, which contains hex() and oct().
2920 These are the PEP 3127 version of these functions, designed to be
2921 compatible with the hex() and oct() builtins from Python 3.0. They
2922 differ slightly in their output formats from the existing, unchanged
2923 Python 2.6 builtins. The expected usage of the future_builtins
2924 module is:
2925 from future_builtins import hex, oct
2926
Eric Smith7ef40bf2008-02-20 23:34:22 +00002927- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2928 exponents for exponents with absolute value < 100. Follows C99
2929 standard. This is a change on Windows, which would use 3 digits.
2930 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2931 so that any alterations it does to the resulting string will be
2932 available in stringlib/formatter.h (for float.__format__).
2933
Eric Smith5a3c1352008-02-19 13:21:56 +00002934- Implemented PEP 3101, Advanced String Formatting. This adds a new
2935 builtin format(); a format() method for str and unicode; a
2936 __format__() method to object, str, unicode, int, long, float, and
2937 datetime; the class string.Formatter; and the C API
2938 PyObject_Format().
2939
Georg Brandl3ee81df2008-05-17 18:14:43 +00002940- Fixed several potential crashes, all caused by specially crafted
2941 __del__ methods exploiting objects in temporarily inconsistent
2942 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002943
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002944- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002945 prevent a possible crash: an Abstract Base Class would try to access
2946 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002947

2949 real or imaginary part.

2952 in order to allow pymalloc to free more arenas. Python may give back
2953 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002954
Georg Brandl3ee81df2008-05-17 18:14:43 +00002955- Issue #2045: Fix an infinite recursion triggered when printing a
2956 subclass of collections.defaultdict, if its default_factory is set
2957 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002958
Christian Heimesf75dbef2008-02-08 00:11:31 +00002959- Fixed a minor memory leak in dictobject.c. The content of the free
2960 list was not freed on interpreter shutdown.
2961
Georg Brandl5a7eca12010-03-21 19:29:04 +00002962- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00002963 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002964
Georg Brandl3ee81df2008-05-17 18:14:43 +00002965- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2966 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``

2968
Georg Brandl3ee81df2008-05-17 18:14:43 +00002969- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2970 calls. Python expected the return type int but the fork familie
2971 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002972
Georg Brandl3ee81df2008-05-17 18:14:43 +00002973- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2974 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002975
Georg Brandl3ee81df2008-05-17 18:14:43 +00002976- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2977 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002978
Georg Brandl3ee81df2008-05-17 18:14:43 +00002979- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2980 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00002982- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2983 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002984
Georg Brandl3ee81df2008-05-17 18:14:43 +00002985- Patch #1473257: generator objects gain a gi_code attribute. This is
2986 the same object as the func_code attribute of the function that
2987 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002988
Georg Brandl3ee81df2008-05-17 18:14:43 +00002989- Issue #1920: "while 0" statements were completely removed by the
2990 compiler, even in the presence of an "else" clause, which is
2991 supposed to be run when the condition is false. Now the compiler
2992 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002993
Guido van Rossumeead05f2008-01-24 18:21:02 +00002994- A few crashers fixed: weakref_in_del.py (issue #1377858);
2995 loosing_dict_ref.py (issue #1303614, test67.py);
2996 borrowed_ref_[34].py (not in tracker).
2997
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002998- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002999 suppressed while an extension is loaded by calling SetErrorMode in
3000 dynload_win.c. The error is still reported properly.
3001
Georg Brandl3ee81df2008-05-17 18:14:43 +00003002- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003003 several extension methods and modules do not work without unicode
3004 support.
3005
Georg Brandl26543b12008-01-21 18:36:51 +00003006- Issue #1882: when compiling code from a string, encoding cookies in the
3007 second line of code were not always recognized correctly.
3008
Georg Brandl14404b62008-01-19 19:27:05 +00003009- Issue #1679: "0x" was taken as a valid integer literal.
3010
Georg Brandl6caad7d2008-01-26 14:19:22 +00003011- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003012 added.
3013
Christian Heimesc94e2b52008-01-14 04:13:37 +00003014- sys.float_info / PyFloat_GetInfo: The floating point information
3015 object was converted from a dict to a specialized structseq object.
3016
Georg Brandl3ee81df2008-05-17 18:14:43 +00003017- Patch #1816: Added sys.flags structseq. It exposes the status of
3018 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003019
Georg Brandl3ee81df2008-05-17 18:14:43 +00003020- Objects/structseq.c: Implemented new structseq representation. The
3021 patch makes structseqs (e.g. the return value of os.stat) more
3022 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003023
Georg Brandl3ee81df2008-05-17 18:14:43 +00003024- Patch #1700288: added a type attribute cache that caches method
3025 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003026
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003027- Bug #1776: __import__() no longer accepts filenames on any platform.
3028 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003029
Georg Brandlaed6c662008-01-07 17:25:53 +00003030- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3031
Georg Brandl3ee81df2008-05-17 18:14:43 +00003032- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3033 envvar and sys.dont_write_bytecode attribute. All these can be set
3034 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003035
Georg Brandl3ee81df2008-05-17 18:14:43 +00003036- Improve some exception messages when Windows fails to load an
3037 extension module. Now we get for example '%1 is not a valid Win32
3038 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003039

3043 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003044
Christian Heimes0a8143f2007-12-18 23:22:54 +00003045- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003046 and INF. float("nan"), float("inf") and float("-inf") now work on
3047 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003048
Georg Brandl3ee81df2008-05-17 18:14:43 +00003049- Compiler now generates simpler and faster code for dictionary
3050 literals. The oparg for BUILD_MAP now indicates an estimated
3051 dictionary size. There is a new opcode, STORE_MAP, for adding
3052 entries to the dictionary.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003062- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003063 SystemError.
3064
Nick Coghlanef01d822007-12-03 12:55:17 +00003065- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00003081- Patch #1739468: Directories and zipfiles containing a __main__.py
3082 file can now be directly executed by passing their name to the
3083 interpreter. The directory/zipfile is automatically inserted as the
3084 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003085
Georg Brandl3ee81df2008-05-17 18:14:43 +00003086- Issue #1265: Fix a problem with sys.settrace, if the tracing
3087 function uses a generator expression when at the same time the
3088 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003089
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003090- sets and frozensets now have an isdisjoint() method.
3091
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003092- optimize the performance of builtin.sum().
3093
Neal Norwitz44f326e2007-10-05 05:29:17 +00003094- Fix warnings found by the new version of the Coverity checker.
3095
Georg Brandl5a7eca12010-03-21 19:29:04 +00003096- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003097 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3098 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003099
Georg Brandl3ee81df2008-05-17 18:14:43 +00003100- Issue #1686386: Tuple's tp_repr did not take into account the
3101 possibility of having a self-referential tuple, which is possible
3102 from C code. Nor did object's tp_str consider that a type's tp_str
3103 could do something that could lead to an inifinite recursion.
3104 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3105 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003106
Georg Brandl3ee81df2008-05-17 18:14:43 +00003107- Issue #1164: It was possible to trigger deadlock when using the
3108 'print' statement to write to a file since the GIL was not released
3109 as needed. Now PyObject_Print() does the right thing along with
3110 various tp_print implementations of the built-in types and those in
3111 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003112
Georg Brandl3ee81df2008-05-17 18:14:43 +00003113- Issue #1147: Exceptions were directly allowing string exceptions in
3114 their throw() method even though string exceptions no longer
3115 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003116
Georg Brandl3ee81df2008-05-17 18:14:43 +00003117- Issue #1096: Prevent a segfault from getting the repr of a very
3118 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003119
Brett Cannon1e534b52007-09-07 04:18:30 +00003120- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003121 PyObject_Call() never calling back out to Python code to trigger
3122 recursion depth updates/checks. Required the creation of a static
3123 RuntimeError instance in case normalizing an exception put the
3124 recursion check value past its limit. Fixes crashers
3125 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003126
Georg Brandl3ee81df2008-05-17 18:14:43 +00003127- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003140- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003141 __*__ attributes. (Some already existed, e.g., __doc__ and
3142 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003143
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003144- Add -3 option to the interpreter to warn about features that are
3145 deprecated and will be changed/removed in Python 3.0.
3146
Georg Brandl2134e752007-05-21 20:34:16 +00003147- Patch #1686487: you can now pass any mapping after '**' in function
3148 calls.
3149
Collin Winter62903052007-05-18 23:11:24 +00003150- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003151 "except E as target:". This is to provide forwards compatibility
3152 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003153
Brett Cannon229cee22007-05-05 01:34:02 +00003154- Deprecate BaseException.message as per PEP 352.
3155
Georg Brandl3ee81df2008-05-17 18:14:43 +00003156- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003157 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003158
Vinay Sajip8549ce32007-05-06 17:53:37 +00003159- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003160 setting a plain string, ie don't expand to single letter identifiers.
3161
Raymond Hettinger13936692007-04-11 18:40:58 +00003162- Request #1191699: Slices can now be pickled.
3163
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003164- Request #1193128: str.translate() now allows a None argument for
3165 translations that only remove characters without re-mapping the
3166 remaining characters.
3167
Georg Brandl5cb76c12007-03-21 09:00:39 +00003168- Patch #1682205: a TypeError while unpacking an iterable is no longer
3169 masked by a generic one with the message "unpack non-sequence".
3170
Neal Norwitzaa754b72007-03-21 06:39:48 +00003171- Remove unused file Python/fmod.c.
3172
Guido van Rossum143b5642007-03-23 04:58:42 +00003173- Bug #1683368: The object.__init__() and object.__new__() methods are
3174 now stricter in rejecting excess arguments. The only time when
3175 either allows excess arguments is when it is not overridden and the
3176 other one is. For backwards compatibility, when both are
3177 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003178 warning later). Also, type.__init__() insists on the same signature
3179 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003180
Georg Brandl3ee81df2008-05-17 18:14:43 +00003181- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3182 object to complex using its __complex__() method before falling back
3183 to the __float__() method. Therefore, the functions in the cmath
3184 module now can operate on objects that define a __complex__()
3185 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003186
Georg Brandl3ee81df2008-05-17 18:14:43 +00003187- Patch #1623563: allow __class__ assignment for classes with
3188 __slots__. The old and the new class are still required to have the
3189 same slot names.

3202
Georg Brandl7b9c5552007-03-12 14:30:05 +00003203- Bug #1678647: write a newline after printing an exception in any
3204 case, even when converting the value to a string failed.
3205
Georg Brandl871f1bc2007-03-12 13:17:36 +00003206- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003207 its argument, if it exists. If not, it will work like before. This
3208 allows customizing the output of dir() in the presence of a
3209 __getattr__().

Facundo Batistad918a652007-04-24 13:54:38 +00003732- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003733 the client's request was successfully received, understood, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00003774 AttributeError instead of an IOError when the server's response
3775 didn't contain a valid HTTP status line.

Georg Brandl92a6bae2007-03-13 17:43:32 +00003808- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003809 are set for invalid interpolation sequences that would lead to
3810 errors on reading back those values.

3866 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00004259 time so that opening a database previously created with the DB_DUP
4260 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4261 opens. Specifically: dictionary assignment to a DB object will
4262 replace all values for a given key when the database allows
4263 duplicate values. DB users should use DB.put(k, v) when they want
4264 to store duplicates; not DB[k] = v.

4271 characters with ASCII value less than 32. Also, it correctly quotes
4272 dots only if they occur on a single line, as opposed to the previous
4273 behavior of quoting dots if they are the second character of any
4274 line.
