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.

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

1021 exceptions.
1022
Benjamin Petersonc6e80eb2008-12-21 17:01:26 +00001023- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

1029
Vinay Sajip6badbe92009-01-20 22:49:13 +00001030- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Georg Brandld2094602008-12-05 08:51:30 +00001031 method on file objects with closefd=False. The file descriptor is still
1032 kept open but the file object behaves like a closed file. The ``FileIO``
1033 object also got a new readonly attribute ``closefd``.
1034
Georg Brandlfa71a902008-12-05 09:08:28 +00001035- Issue #3689: The list reversed iterator now supports __length_hint__

Jesse Nollerb48cfa62009-03-30 16:19:10 +00001103 socket.SO_REUSEADDR on all connections so that the user no longer needs
1104 to wait 120 seconds for the socket to expire.
1105
1106- Adjusted _tkinter to compile without warnings when WITH_THREAD is not

1406What's New in Python 2.6.1
1407==========================
1408
1409*Release date: 04-Dec-2008*
1410
1411Core and Builtins
1412-----------------
1413
1414- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1415 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1416 instead of throwing a MemoryError.
1417
1418- Issue #4367: Python would segfault during compiling when the unicodedata
1419 module couldn't be imported and \N escapes were present.
1420
1421- Issue #4348: Some bytearray methods returned that didn't cause any change to
1422 the bytearray, returned the same bytearray instead of a copy.
1423
1424- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1425
1426- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1427
1428- Issue #4048: The parser module now correctly validates relative imports.
1429
1430- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

1434 method does not return iterators for the 4th and 5th items.
1435
1436- Issue #4209: Enabling unicode_literals and the print_function in the same
1437 __future__ import didn't work.
1438
1439- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1440 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1441 really executed because I cannot move to such directory on win2k)
1442
1443- Issue #4069: When set.remove(element) is used with a set element, the element
1444 is temporarily replaced with an equivalent frozenset. But the eventual
1445 KeyError would always report the empty frozenset([]) as the missing key. Now
1446 it correctly refers to the initial element.
1447
1448- Fixed C99 style comments in several files. Python is now C89 compatible
1449 again.

1593Core and Builtins
1594-----------------
1595
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001596- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1597
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001598- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1599 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1600 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1601 ``printf`` function, whereas PyString_FromFormat has an independent
1602 implementation and uses "%zd" on all platforms for size_t values.
1603 This makes a difference on win64, where ``printf`` needs "%Id" to display
1604 64bit values.
1605
Benjamin Peterson97179b02008-09-09 20:55:01 +00001606- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1607 error.
1608
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001609- Issue #3777: long() applied to a float object now always return a long
1610 object; previously an int would be returned for small values. the __long__
1611 method is allowed to return either an int or a long, but the behaviour of
1612 float objects should not change to respect backward compatibility.
1613
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001614- Issue #3751: str.rpartition would perform a left-partition when called with
1615 a unicode argument.
1616
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001617- Issue #3683: Fix compilation when --without-threads is given.
1618
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001619- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001620 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001621 was correctly parsed but parsing of subsequent arguments failed.
1622
Vinay Sajip35e3b032008-09-01 14:33:59 +00001623- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001624 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1625 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1626 when given a tuple of classes as second argument, were looking up
1627 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1628 type object.
1629
Neal Norwitz18aa3882008-08-24 05:04:52 +00001630- Fix crashes on memory allocation failure found with failmalloc.
1631
1632- Fix memory leaks found with valgrind and update suppressions file.
1633
1634- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1635
1636- Fix problem using wrong name in decimal module reported by pychecker.
1637
Christian Heimes7d4c3172008-08-22 19:47:25 +00001638- Silenced another compiler warning about a used but not defined
1639 function 'stringlib_contains_obj'.
1640
Benjamin Peterson712ee922008-08-24 18:10:20 +00001641- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
1642 ``__delslice__``.
1643
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00001644- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
1645 library targets in the Makefile.
1646
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001647- Issue #1204: The configure script now tests for additional libraries
1648 that may be required when linking against readline. This fixes issues
1649 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
1650

Amaury Forgeot d'Arc24cb3822008-09-11 20:56:13 +00001659- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
1660 stack usage in the case of deeply nested objects.
1661

Nick Coghland2e09382008-09-11 12:11:06 +00001666- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
1667 silent misbehaviour when a single instance is nested in multiple
1668 with statements, or when the methods are invoked in the wrong order.
1669
Vinay Sajip844f7412008-09-09 13:42:08 +00001670- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.
1671
Nick Coghland2e09382008-09-11 12:11:06 +00001672- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001673 return a list or None rather than a custom object.
1674
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00001675- Issue #1638033: Cookie.Morsel gained the httponly attribute.

1682 its symbolic link.
1683
Vinay Sajip65d66e12008-09-04 07:31:21 +00001684- Issue #3772: Fixed regression problem in StreamHandler.emit().

1699 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1700 for catch_warnings() also led to an improvement in the raising of a
1701 DeprecationWarning related to warnings.warn_explicit().
1702
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001703- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001764What's New in Python 2.6 beta 3?
1765================================
1766
Barry Warsaw07a4a382008-08-21 01:15:08 +00001767*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001768
1769Core and Builtins
1770-----------------
1771
Guido van Rossumf8402962008-08-20 15:01:50 +00001772- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1773 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1774 extensions do not automatically benefit from the class attribute
1775 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1776 to their tp_flags field if they care. This is a backwards
1777 compatibility feature; in 3.0, all types will use the cache by
1778 default.
1779
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001780- Keyword arguments can now follow starred arguments. (``f(a, *args,
1781 keyword=23)`` is now valid syntax.)
1782
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001783- ctypes function pointers that are COM methods have a boolean True
1784 value again.
1785
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001786- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1787 by denying s# to parse objects that have a releasebuffer procedure,
1788 and introducing s*.
1789
Georg Brandl1e13ea92008-08-11 09:07:59 +00001790- Issue #3537: Fix an assertion failure when an empty but presized dict
1791 object was stored in the freelist.
1792
Mark Dickinsonb6467572008-08-04 21:30:09 +00001793- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1794 ValueError consistently across platforms.
1795
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001796- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1797 (64bit Unix, for example), unichr() would truncate its argument and return
1798 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1799
Neal Norwitze7d8be82008-07-31 17:17:14 +00001800- Apply security patches from Apple.
1801
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001802- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1803 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1804
Antoine Pitrou92f82162008-07-25 22:22:08 +00001805- Issue #1819: function calls with several named parameters are now on
1806 average 35% faster (as measured by pybench).
1807
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001808- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1809 the python debugger steps into a class statement: the free variables (local
1810 variables defined in an outer scope) would be deleted from the outer scope.
1811
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001812- Issue #2620: Overflow checking when allocating or reallocating memory
1813 was not always being done properly in some python types and extension
1814 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1815 all been updated to perform better checks and places in the code that
1816 would previously leak memory on the error path when such an allocation
1817 failed have been fixed.
1818
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001819Library
1820-------
1821
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001822- Issue #3612: Added some missing basic types in ctypes.wintypes.
1823
Benjamin Petersone977ad42008-08-20 01:42:01 +00001824- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1825 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1826
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001827- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1828 version reported by these tools does not necessarily follow the python
1829 version numbering scheme, so the module is less strict when parsing it.
1830
Nick Coghlanf70385a2008-08-18 12:42:46 +00001831- Issue #2235: Added Py3k warnings for types which will become unhashable
1832 under the stricter __hash__ inheritance rules in 3.0. Several types
1833 which did not meet the rules for hash invariants and were already
1834 unhashable in 3.0 have now been explicitly flagged as unhashable in
1835 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1836 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1837
Brett Cannon88f801d2008-08-18 00:46:22 +00001838- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1839 imported into the module but exposed as part of the module's API.
1840
Brett Cannon7b96f072008-08-18 00:41:11 +00001841- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1842
Brett Cannon46225e72008-08-18 00:36:52 +00001843- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001845- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1846
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001847- Issue #3575: Incremental decoder's decode function now takes bytearray
1848 by using 's*' instead of 't#'.
1849
Jesus Cea585ad8a2009-07-02 15:37:21 +00001850- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001851 fails unicode conversion on 2nd parameter. (windows only)
1852
Facundo Batista94f243a2008-08-17 03:38:39 +00001853- Issue 2464. urllib2 now supports a malformation in the URL received
1854 in a redirect.
1855
Brett Cannonabe423e2008-08-16 21:47:07 +00001856- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001857 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001858
Facundo Batistaeb90b782008-08-16 14:44:07 +00001859- Issue #2776: fixed small issue when handling an URL with double slash
1860 after a 302 response in the case of not going through a proxy.
1861
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001862- Issue #2676: in the email package, content-type parsing was hanging on
1863 pathological input because of quadratic or exponential behaviour of a
1864 regular expression.
1865
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001866- Issue #3476: binary buffered reading through the new "io" library is now
1867 thread-safe.
1868
Brett Cannonbf3157b2008-08-14 05:00:03 +00001869- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1870 since mimetools itself is deprecated. Because modules are cached, all
1871 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1872
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001873- Issue #3134: shutil referenced undefined WindowsError symbol.
1874
Robert Schuppenies14646332008-08-10 11:01:53 +00001875- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1876 menu entries were not deleted.
1877
Brett Cannon83e81842008-08-09 23:30:55 +00001878- Copied the implementation of reduce() to _functools.reduce() to have a
1879 version that did not raise a DeprecationWarning under -3.

Antoine Pitroude781a42008-08-09 12:43:23 +00001907 asking for a specific length. This problem only affected files opened

1964-----------------
1965
Georg Brandl3e483f62008-07-16 22:57:41 +00001966- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1967 its methods now allow for items objects that can be converted to
1968 an integer using operator.index().
1969
Mark Dickinson64b7e502008-07-16 09:40:03 +00001970- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1971 produced a ValueError instead of giving the correct float.
1972
Eric Smitha5fa5a22008-07-16 00:11:49 +00001973- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1974 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1975
Mark Dickinson7103aa42008-07-15 19:08:33 +00001976- Issue #3008: the float type has a new instance method 'float.hex'
1977 and a new class method 'float.fromhex' to convert floating-point
1978 numbers to and from hexadecimal strings, respectively.
1979
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001980- Issue #2235: __hash__ is once again inherited by default. To allow
1981 collections.Hashable to remain meaningful in the presence of the
1982 default hash implementation (object.__hash__), it is now possible
1983 to explicit block inheritance of hash by setting __hash__=None at
1984 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1985 level.
1986
Nick Coghlanb028f502008-07-13 14:52:36 +00001987- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1988 the parent module cannot be found while performing an absolute import.
1989 This means that an incorrectly defined __package__ attribute will
1990 now only prevent relative imports in that module rather than causing
1991 all imports from that module to fail.
1992
Nick Coghlan14ff9942008-07-08 14:21:42 +00001993- Issue #2517: Allow unicode messages in Exceptions again by correctly

2003 another thread's dictionary.
2004
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002005- Issue #3004: Minor change to slice.indices(): the start and stop
2006 arguments are now treated identically, making the behaviour easier
2007 to describe and understand. For example, slice(None, -10,
2008 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2009 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2010 10, -1).
2011
Georg Brandl278fc502008-07-19 12:46:12 +00002012- Issue #3219: Calling a function with repeated keyword arguments,
2013 f(a=2, a=23), would not cause a syntax error. This was a regression
2014 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002052- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2053 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002054 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002055 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002071- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

2459
Brett Cannonb61d8012008-05-11 23:39:04 +00002460- ``Lib/lib-old`` is now added to sys.path.
2461
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002462- On MacOS X it is now possible to install the framework in 64-bit
2463 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002464 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002465
2466 This is controlled by the configure argument ``--with-universal-archs``:
2467
2468 - ``--with-universal-archs=all``: install 4-way universal
2469
2470 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2471
2472 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2473
2474 This option should be used in combination with ``--enable-universalsdk=``.
2475
2476 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 +00002485
2486- The PyString functions have been renamed to PyBytes. A batch of
2487 defines were added so that the linker still sees the original
2488 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002526- Issue #1631171: Re-implement the 'warnings' module in C (the
2527 original Python code has been kept as backup). This will allow for
2528 using the 'warning's machinery in such places as the parser where
2529 use of pure Python code is not possible. Both the ``showarning()``
2530 and ``formatwarning()`` gain an optional 'line' argument which is
2531 not called by default for backwards-compatibility reasons. Setting
2532 ``warnings.showwarning()`` to an implementation that lacks support
2533 for the ``line`` argument will raise a DeprecationWarning.

2557
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002558- The getpass module has been improved on Unix. It now uses /dev/tty
2559 by default and uses stderr instead of stdout. A GetPassWarning is
2560 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00002561

2573 removed and replaced by pure python code.
Amaury Forgeot d'Arc02f33b42008-04-08 23:10:07 +00002574
Georg Brandl3ee81df2008-05-17 18:14:43 +00002575- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002576 extension modules between 32 and 64 bit platforms. See the distutls

2589 so the controlled environment will more closely mirror the typical
2590 script environment. This supports setup.py scripts that refer to
2591 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002596- Issue #2550: The approach used by client/server code for obtaining
2597 ports to listen on in network-oriented tests has been refined in an
2598 effort to facilitate running multiple instances of the entire
2599 regression test suite in parallel without issue.
2600 test_support.bind_port() has been fixed such that it will always
2601 return a unique port -- which wasn't always the case with the
2602 previous implementation, especially if socket options had been set
2603 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2604 new implementation of bind_port() will actually raise an exception
2605 if it is passed an AF_INET/SOCK_STREAM socket with either the
2606 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2607 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2608 the socket it's been passed. This currently only applies to
2609 Windows. This option prevents any other sockets from binding to the
2610 host/port we've bound to, thus removing the possibility of the
2611 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2612 when a second SOCK_STREAM socket binds and accepts to a host/port
2613 that's already been bound by another socket. The optional preferred
2614 port parameter to bind_port() has been removed. Under no
2615 circumstances should tests be hard coding ports!
2616
2617 test_support.find_unused_port() has also been introduced, which will
2618 pass a temporary socket object to bind_port() in order to obtain an
2619 unused port. The temporary socket object is then closed and
2620 deleted, and the port is returned. This method should only be used
2621 for obtaining an unused port in order to pass to an external program
2622 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2623 a parameter to a server-oriented class that doesn't give you direct
2624 access to the underlying socket used.
2625
2626 Finally, test_support.HOST has been introduced, which should be used
2627 for the host argument of any relevant socket calls (i.e. bind and
2628 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002629
2630 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002631 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002632 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2633 test_asynchat and test_socket_ssl.
2634
Georg Brandl3ee81df2008-05-17 18:14:43 +00002635 It is now possible for multiple instances of the regression test
2636 suite to run in parallel without issue.

2903-----------------
2904
Fred Drakea8ee94b2008-03-01 02:45:07 +00002905- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002906 644. The mode is now inherited from the py file.

2909
2910- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002911
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002912- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002913 issue 215555 for a discussion.
2914
Eric Smitha73fbe72008-02-23 03:09:44 +00002915- Added the future_builtins module, which contains hex() and oct().
2916 These are the PEP 3127 version of these functions, designed to be
2917 compatible with the hex() and oct() builtins from Python 3.0. They
2918 differ slightly in their output formats from the existing, unchanged
2919 Python 2.6 builtins. The expected usage of the future_builtins
2920 module is:
2921 from future_builtins import hex, oct
2922
Eric Smith7ef40bf2008-02-20 23:34:22 +00002923- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2924 exponents for exponents with absolute value < 100. Follows C99
2925 standard. This is a change on Windows, which would use 3 digits.
2926 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2927 so that any alterations it does to the resulting string will be
2928 available in stringlib/formatter.h (for float.__format__).
2929
Eric Smith5a3c1352008-02-19 13:21:56 +00002930- Implemented PEP 3101, Advanced String Formatting. This adds a new
2931 builtin format(); a format() method for str and unicode; a
2932 __format__() method to object, str, unicode, int, long, float, and
2933 datetime; the class string.Formatter; and the C API
2934 PyObject_Format().
2935
Georg Brandl3ee81df2008-05-17 18:14:43 +00002936- Fixed several potential crashes, all caused by specially crafted
2937 __del__ methods exploiting objects in temporarily inconsistent
2938 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002939
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002940- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002941 prevent a possible crash: an Abstract Base Class would try to access
2942 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002943

Georg Brandl3ee81df2008-05-17 18:14:43 +00002947- Clear all free lists during a gc.collect() of the highest generation
2948 in order to allow pymalloc to free more arenas. Python may give back
2949 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002950
Georg Brandl3ee81df2008-05-17 18:14:43 +00002951- Issue #2045: Fix an infinite recursion triggered when printing a
2952 subclass of collections.defaultdict, if its default_factory is set
2953 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002954
Christian Heimesf75dbef2008-02-08 00:11:31 +00002955- Fixed a minor memory leak in dictobject.c. The content of the free
2956 list was not freed on interpreter shutdown.
2957
Georg Brandl5a7eca12010-03-21 19:29:04 +00002958- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00002959 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002960
Georg Brandl3ee81df2008-05-17 18:14:43 +00002961- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2962 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002963 to compact the internal free lists of pre-allocted ints and floats.
2964
Georg Brandl3ee81df2008-05-17 18:14:43 +00002965- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2966 calls. Python expected the return type int but the fork familie
2967 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002968
Georg Brandl3ee81df2008-05-17 18:14:43 +00002969- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2970 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002971
Georg Brandl3ee81df2008-05-17 18:14:43 +00002972- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2973 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002974
Georg Brandl3ee81df2008-05-17 18:14:43 +00002975- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2976 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00002978- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2979 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002980
Georg Brandl3ee81df2008-05-17 18:14:43 +00002981- Patch #1473257: generator objects gain a gi_code attribute. This is
2982 the same object as the func_code attribute of the function that
2983 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002984
Georg Brandl3ee81df2008-05-17 18:14:43 +00002985- Issue #1920: "while 0" statements were completely removed by the
2986 compiler, even in the presence of an "else" clause, which is
2987 supposed to be run when the condition is false. Now the compiler
2988 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002989
Guido van Rossumeead05f2008-01-24 18:21:02 +00002990- A few crashers fixed: weakref_in_del.py (issue #1377858);
2991 loosing_dict_ref.py (issue #1303614, test67.py);
2992 borrowed_ref_[34].py (not in tracker).
2993
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002994- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002995 suppressed while an extension is loaded by calling SetErrorMode in
2996 dynload_win.c. The error is still reported properly.
2997
Georg Brandl3ee81df2008-05-17 18:14:43 +00002998- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002999 several extension methods and modules do not work without unicode
3000 support.
3001
Georg Brandl26543b12008-01-21 18:36:51 +00003002- Issue #1882: when compiling code from a string, encoding cookies in the
3003 second line of code were not always recognized correctly.
3004
Georg Brandl14404b62008-01-19 19:27:05 +00003005- Issue #1679: "0x" was taken as a valid integer literal.
3006
Georg Brandl6caad7d2008-01-26 14:19:22 +00003007- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003008 added.
3009
Christian Heimesc94e2b52008-01-14 04:13:37 +00003010- sys.float_info / PyFloat_GetInfo: The floating point information
3011 object was converted from a dict to a specialized structseq object.
3012
Georg Brandl3ee81df2008-05-17 18:14:43 +00003013- Patch #1816: Added sys.flags structseq. It exposes the status of
3014 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003015
Georg Brandl3ee81df2008-05-17 18:14:43 +00003016- Objects/structseq.c: Implemented new structseq representation. The
3017 patch makes structseqs (e.g. the return value of os.stat) more
3018 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003019
Georg Brandl3ee81df2008-05-17 18:14:43 +00003020- Patch #1700288: added a type attribute cache that caches method
3021 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003022
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003023- Bug #1776: __import__() no longer accepts filenames on any platform.
3024 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003025
Georg Brandlaed6c662008-01-07 17:25:53 +00003026- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3027
Georg Brandl3ee81df2008-05-17 18:14:43 +00003028- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3029 envvar and sys.dont_write_bytecode attribute. All these can be set
3030 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003031
Georg Brandl3ee81df2008-05-17 18:14:43 +00003032- Improve some exception messages when Windows fails to load an
3033 extension module. Now we get for example '%1 is not a valid Win32
3034 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003035
Georg Brandl3ee81df2008-05-17 18:14:43 +00003036- Bug #1481296: Fixed long(float('nan')) != 0L.

Christian Heimes0a8143f2007-12-18 23:22:54 +00003041- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003042 and INF. float("nan"), float("inf") and float("-inf") now work on
3043 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003044
Georg Brandl3ee81df2008-05-17 18:14:43 +00003045- Compiler now generates simpler and faster code for dictionary
3046 literals. The oparg for BUILD_MAP now indicates an estimated
3047 dictionary size. There is a new opcode, STORE_MAP, for adding
3048 entries to the dictionary.

3060
Nick Coghlanef01d822007-12-03 12:55:17 +00003061- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00003077- Patch #1739468: Directories and zipfiles containing a __main__.py
3078 file can now be directly executed by passing their name to the
3079 interpreter. The directory/zipfile is automatically inserted as the
3080 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003081
Georg Brandl3ee81df2008-05-17 18:14:43 +00003082- Issue #1265: Fix a problem with sys.settrace, if the tracing
3083 function uses a generator expression when at the same time the
3084 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003085
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003086- sets and frozensets now have an isdisjoint() method.
3087
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003088- optimize the performance of builtin.sum().
3089
Neal Norwitz44f326e2007-10-05 05:29:17 +00003090- Fix warnings found by the new version of the Coverity checker.
3091
Georg Brandl5a7eca12010-03-21 19:29:04 +00003092- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003093 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3094 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003095
Georg Brandl3ee81df2008-05-17 18:14:43 +00003096- Issue #1686386: Tuple's tp_repr did not take into account the
3097 possibility of having a self-referential tuple, which is possible
3098 from C code. Nor did object's tp_str consider that a type's tp_str
3099 could do something that could lead to an inifinite recursion.
3100 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3101 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003102
Georg Brandl3ee81df2008-05-17 18:14:43 +00003103- Issue #1164: It was possible to trigger deadlock when using the
3104 'print' statement to write to a file since the GIL was not released
3105 as needed. Now PyObject_Print() does the right thing along with
3106 various tp_print implementations of the built-in types and those in
3107 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003108
Georg Brandl3ee81df2008-05-17 18:14:43 +00003109- Issue #1147: Exceptions were directly allowing string exceptions in
3110 their throw() method even though string exceptions no longer
3111 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003112
Georg Brandl3ee81df2008-05-17 18:14:43 +00003113- Issue #1096: Prevent a segfault from getting the repr of a very
3114 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003115
Brett Cannon1e534b52007-09-07 04:18:30 +00003116- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003117 PyObject_Call() never calling back out to Python code to trigger
3118 recursion depth updates/checks. Required the creation of a static
3119 RuntimeError instance in case normalizing an exception put the
3120 recursion check value past its limit. Fixes crashers
3121 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003122
Georg Brandl3ee81df2008-05-17 18:14:43 +00003123- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003136- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003137 __*__ attributes. (Some already existed, e.g., __doc__ and
3138 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003139
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003140- Add -3 option to the interpreter to warn about features that are
3141 deprecated and will be changed/removed in Python 3.0.
3142
Georg Brandl2134e752007-05-21 20:34:16 +00003143- Patch #1686487: you can now pass any mapping after '**' in function
3144 calls.
3145
Collin Winter62903052007-05-18 23:11:24 +00003146- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003147 "except E as target:". This is to provide forwards compatibility
3148 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003149
Brett Cannon229cee22007-05-05 01:34:02 +00003150- Deprecate BaseException.message as per PEP 352.
3151
Georg Brandl3ee81df2008-05-17 18:14:43 +00003152- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003153 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003154
Vinay Sajip8549ce32007-05-06 17:53:37 +00003155- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003156 setting a plain string, ie don't expand to single letter identifiers.
3157
Raymond Hettinger13936692007-04-11 18:40:58 +00003158- Request #1191699: Slices can now be pickled.
3159
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003160- Request #1193128: str.translate() now allows a None argument for
3161 translations that only remove characters without re-mapping the
3162 remaining characters.
3163
Georg Brandl5cb76c12007-03-21 09:00:39 +00003164- Patch #1682205: a TypeError while unpacking an iterable is no longer
3165 masked by a generic one with the message "unpack non-sequence".
3166
Neal Norwitzaa754b72007-03-21 06:39:48 +00003167- Remove unused file Python/fmod.c.
3168
Guido van Rossum143b5642007-03-23 04:58:42 +00003169- Bug #1683368: The object.__init__() and object.__new__() methods are
3170 now stricter in rejecting excess arguments. The only time when
3171 either allows excess arguments is when it is not overridden and the
3172 other one is. For backwards compatibility, when both are
3173 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003174 warning later). Also, type.__init__() insists on the same signature
3175 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003176
Georg Brandl3ee81df2008-05-17 18:14:43 +00003177- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3178 object to complex using its __complex__() method before falling back
3179 to the __float__() method. Therefore, the functions in the cmath
3180 module now can operate on objects that define a __complex__()
3181 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003182
Georg Brandl3ee81df2008-05-17 18:14:43 +00003183- Patch #1623563: allow __class__ assignment for classes with
3184 __slots__. The old and the new class are still required to have the
3185 same slot names.

3191 ``object.__reduce_ex__()`` is called with an object that is faking
3192 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003193
Georg Brandl3ee81df2008-05-17 18:14:43 +00003194- Patch #1680015: Don't modify __slots__ tuple if it contains an

3198
Georg Brandl7b9c5552007-03-12 14:30:05 +00003199- Bug #1678647: write a newline after printing an exception in any
3200 case, even when converting the value to a string failed.
3201
Georg Brandl871f1bc2007-03-12 13:17:36 +00003202- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003203 its argument, if it exists. If not, it will work like before. This
3204 allows customizing the output of dir() in the presence of a
3205 __getattr__().

Georg Brandl4e933132006-09-06 20:05:58 +00003320- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003338 generator expressions (x for x, in ... ) works again. Fixing this
3339 problem required changing the .pyc magic number. This means that

Guido van Rossum8bc09652008-02-21 18:18:37 +00003379- Removed uses of dict.has_key() from distutils, and uses of

Georg Brandl3ee81df2008-05-17 18:14:43 +00003729 the client's request was successfully received, understood, and

3740 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3741 work started with create_connection() and timeout in httplib, and

3743
Vinay Sajip8549ce32007-05-06 17:53:37 +00003744- Patch #1676823: Added create_connection() to socket.py, which may be

Georg Brandl3ee81df2008-05-17 18:14:43 +00003770 AttributeError instead of an IOError when the server's response
3771 didn't contain a valid HTTP status line.

3803
Georg Brandl92a6bae2007-03-13 17:43:32 +00003804- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003805 are set for invalid interpolation sequences that would lead to
3806 errors on reading back those values.

3862 TestCase and TestSuite subclasses (not instances) are no longer
3863 accepted in TestSuite.addTest(). This should cause no

3866 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004255 time so that opening a database previously created with the DB_DUP
4256 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4257 opens. Specifically: dictionary assignment to a DB object will
4258 replace all values for a given key when the database allows
4259 duplicate values. DB users should use DB.put(k, v) when they want
4260 to store duplicates; not DB[k] = v.

4267 characters with ASCII value less than 32. Also, it correctly quotes
4268 dots only if they occur on a single line, as opposed to the previous
4269 behavior of quoting dots if they are the second character of any
4270 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004271
