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.

43 the zlib itself doesn't give any detailed explanation.
44
Mark Dickinson47e3bf22010-05-10 16:16:52 +000045- Issue #8674: Fixed a number of incorrect or undefined-behaviour-inducing

53
54- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing
55 error messages when accessing undefined class attributes because of the cheap
56 inheritance with the underlying socket object.
57

65 ASCII with backslashreplace error handler if str(value) failed
66
Mark Dickinson1cdfa5f2010-05-04 14:30:32 +000067- Issue #8567: Fix precedence of signals in Decimal module: when a
68 Decimal operation raises multiple signals and more than one of those
69 signals is trapped, the specification determines the order in which
70 the signals should be handled. In many cases this order wasn't
71 being followed, leading to the wrong Python exception being raised.
72
Antoine Pitrou01a255a2010-05-03 16:48:13 +000073- Issue #7865: The close() method of :mod:`io` objects should not swallow

103
Antoine Pitrou53d7d062010-04-25 21:55:45 +0000104- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
105 where the method could block indefinitely if called just before the
106 event loop started running. This also fixes the occasional freezes
107 witnessed in test_httpservers.
108
Antoine Pitrouc689d962010-04-24 20:13:37 +0000109- Issue #5103: SSL handshake would ignore the socket timeout and block

122 a non-infinite timeout. Also make that method friendlier with applications
123 wanting to continue using the socket in clear-text mode, by disabling
124 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
125
Antoine Pitrou878602a2010-04-21 19:41:28 +0000126- Issue #8484: Load all ciphers and digest algorithms when initializing

128 doesn't fail because of an "unknown algorithm".
129
Giampaolo Rodolàa2eb7f62010-04-19 21:56:45 +0000130- Issue #4814: timeout parameter is now applied also for connections resulting

1413What's New in Python 2.6.1
1414==========================
1415
1416*Release date: 04-Dec-2008*
1417
1418Core and Builtins
1419-----------------
1420
1421- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1422 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1423 instead of throwing a MemoryError.
1424
1425- Issue #4367: Python would segfault during compiling when the unicodedata
1426 module couldn't be imported and \N escapes were present.
1427
1428- Issue #4348: Some bytearray methods returned that didn't cause any change to
1429 the bytearray, returned the same bytearray instead of a copy.
1430
1431- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1432
1433- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1434
1435- Issue #4048: The parser module now correctly validates relative imports.
1436
1437- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1438 exec statement.
1439
1440- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1441 method does not return iterators for the 4th and 5th items.
1442
1443- Issue #4209: Enabling unicode_literals and the print_function in the same
1444 __future__ import didn't work.
1445
1446- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1447 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1448 really executed because I cannot move to such directory on win2k)
1449
1450- Issue #4069: When set.remove(element) is used with a set element, the element
1451 is temporarily replaced with an equivalent frozenset. But the eventual
1452 KeyError would always report the empty frozenset([]) as the missing key. Now
1453 it correctly refers to the initial element.
1454
1455- Fixed C99 style comments in several files. Python is now C89 compatible
1456 again.

1600Core and Builtins
1601-----------------
1602
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001603- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1604
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001605- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1606 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1607 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1608 ``printf`` function, whereas PyString_FromFormat has an independent
1609 implementation and uses "%zd" on all platforms for size_t values.
1610 This makes a difference on win64, where ``printf`` needs "%Id" to display
1611 64bit values.
1612
Benjamin Peterson97179b02008-09-09 20:55:01 +00001613- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1614 error.
1615
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001616- Issue #3777: long() applied to a float object now always return a long
1617 object; previously an int would be returned for small values. the __long__
1618 method is allowed to return either an int or a long, but the behaviour of
1619 float objects should not change to respect backward compatibility.
1620
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001621- Issue #3751: str.rpartition would perform a left-partition when called with
1622 a unicode argument.
1623
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001624- Issue #3683: Fix compilation when --without-threads is given.
1625
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001626- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001627 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001628 was correctly parsed but parsing of subsequent arguments failed.
1629
Vinay Sajip35e3b032008-09-01 14:33:59 +00001630- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001631 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1632 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1633 when given a tuple of classes as second argument, were looking up
1634 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1635 type object.
1636
Neal Norwitz18aa3882008-08-24 05:04:52 +00001637- Fix crashes on memory allocation failure found with failmalloc.
1638
1639- Fix memory leaks found with valgrind and update suppressions file.
1640
1641- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1642
1643- Fix problem using wrong name in decimal module reported by pychecker.
1644
Christian Heimes7d4c3172008-08-22 19:47:25 +00001645- Silenced another compiler warning about a used but not defined
1646 function 'stringlib_contains_obj'.
1647
Benjamin Peterson712ee922008-08-24 18:10:20 +00001648- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
1649 ``__delslice__``.
1650
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00001651- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
1652 library targets in the Makefile.
1653
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001654- Issue #1204: The configure script now tests for additional libraries
1655 that may be required when linking against readline. This fixes issues
1656 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
1657

Nick Coghland2e09382008-09-11 12:11:06 +00001673- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
1674 silent misbehaviour when a single instance is nested in multiple
1675 with statements, or when the methods are invoked in the wrong order.
1676
Vinay Sajip844f7412008-09-09 13:42:08 +00001677- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.
1678
Nick Coghland2e09382008-09-11 12:11:06 +00001679- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001680 return a list or None rather than a custom object.
1681
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00001682- Issue #1638033: Cookie.Morsel gained the httponly attribute.

1706 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1707 for catch_warnings() also led to an improvement in the raising of a
1708 DeprecationWarning related to warnings.warn_explicit().
1709
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001710- The deprecation warnings for the old camelCase threading API were removed.

Benjamin Peterson37346b22008-08-23 20:27:43 +00001727Extension Modules
1728-----------------
1729
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001730- Issue #2975: When compiling several extension modules with Visual Studio 2008
1731 from the same python interpreter, some environment variables would grow
1732 without limit.
1733
Benjamin Peterson37346b22008-08-23 20:27:43 +00001734- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001771What's New in Python 2.6 beta 3?
1772================================
1773
Barry Warsaw07a4a382008-08-21 01:15:08 +00001774*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001775
1776Core and Builtins
1777-----------------
1778
Guido van Rossumf8402962008-08-20 15:01:50 +00001779- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1780 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1781 extensions do not automatically benefit from the class attribute
1782 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1783 to their tp_flags field if they care. This is a backwards
1784 compatibility feature; in 3.0, all types will use the cache by
1785 default.
1786
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001787- Keyword arguments can now follow starred arguments. (``f(a, *args,
1788 keyword=23)`` is now valid syntax.)
1789
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001790- ctypes function pointers that are COM methods have a boolean True
1791 value again.
1792
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001793- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1794 by denying s# to parse objects that have a releasebuffer procedure,
1795 and introducing s*.
1796
Georg Brandl1e13ea92008-08-11 09:07:59 +00001797- Issue #3537: Fix an assertion failure when an empty but presized dict
1798 object was stored in the freelist.
1799
Mark Dickinsonb6467572008-08-04 21:30:09 +00001800- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1801 ValueError consistently across platforms.
1802
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001803- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1804 (64bit Unix, for example), unichr() would truncate its argument and return
1805 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1806
Neal Norwitze7d8be82008-07-31 17:17:14 +00001807- Apply security patches from Apple.
1808
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001809- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1810 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1811
Antoine Pitrou92f82162008-07-25 22:22:08 +00001812- Issue #1819: function calls with several named parameters are now on
1813 average 35% faster (as measured by pybench).
1814
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001815- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1816 the python debugger steps into a class statement: the free variables (local
1817 variables defined in an outer scope) would be deleted from the outer scope.
1818
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001819- Issue #2620: Overflow checking when allocating or reallocating memory
1820 was not always being done properly in some python types and extension
1821 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1822 all been updated to perform better checks and places in the code that
1823 would previously leak memory on the error path when such an allocation
1824 failed have been fixed.
1825
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001826Library
1827-------
1828

1830
Benjamin Petersone977ad42008-08-20 01:42:01 +00001831- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1832 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1833
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001834- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1835 version reported by these tools does not necessarily follow the python
1836 version numbering scheme, so the module is less strict when parsing it.
1837
Nick Coghlanf70385a2008-08-18 12:42:46 +00001838- Issue #2235: Added Py3k warnings for types which will become unhashable
1839 under the stricter __hash__ inheritance rules in 3.0. Several types
1840 which did not meet the rules for hash invariants and were already
1841 unhashable in 3.0 have now been explicitly flagged as unhashable in
1842 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1843 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1844
Brett Cannon88f801d2008-08-18 00:46:22 +00001845- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1846 imported into the module but exposed as part of the module's API.
1847
Brett Cannon7b96f072008-08-18 00:41:11 +00001848- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1849
Brett Cannon46225e72008-08-18 00:36:52 +00001850- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001852- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1853
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001854- Issue #3575: Incremental decoder's decode function now takes bytearray
1855 by using 's*' instead of 't#'.
1856
Jesus Cea585ad8a2009-07-02 15:37:21 +00001857- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001858 fails unicode conversion on 2nd parameter. (windows only)
1859
Facundo Batista94f243a2008-08-17 03:38:39 +00001860- Issue 2464. urllib2 now supports a malformation in the URL received
1861 in a redirect.
1862
Brett Cannonabe423e2008-08-16 21:47:07 +00001863- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001864 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001865
Facundo Batistaeb90b782008-08-16 14:44:07 +00001866- Issue #2776: fixed small issue when handling an URL with double slash
1867 after a 302 response in the case of not going through a proxy.
1868
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001869- Issue #2676: in the email package, content-type parsing was hanging on
1870 pathological input because of quadratic or exponential behaviour of a
1871 regular expression.
1872
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001873- Issue #3476: binary buffered reading through the new "io" library is now
1874 thread-safe.
1875
Brett Cannonbf3157b2008-08-14 05:00:03 +00001876- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1877 since mimetools itself is deprecated. Because modules are cached, all
1878 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1879
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001880- Issue #3134: shutil referenced undefined WindowsError symbol.

1972
Georg Brandl3e483f62008-07-16 22:57:41 +00001973- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1974 its methods now allow for items objects that can be converted to
1975 an integer using operator.index().
1976
Mark Dickinson64b7e502008-07-16 09:40:03 +00001977- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1978 produced a ValueError instead of giving the correct float.
1979
Eric Smitha5fa5a22008-07-16 00:11:49 +00001980- Issue #3083: Add alternate (#) formatting for bin, oct, hex output

Mark Dickinson7103aa42008-07-15 19:08:33 +00001983- Issue #3008: the float type has a new instance method 'float.hex'
1984 and a new class method 'float.fromhex' to convert floating-point
1985 numbers to and from hexadecimal strings, respectively.
1986
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001987- Issue #2235: __hash__ is once again inherited by default. To allow
1988 collections.Hashable to remain meaningful in the presence of the
1989 default hash implementation (object.__hash__), it is now possible
1990 to explicit block inheritance of hash by setting __hash__=None at
1991 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1992 level.
1993
Nick Coghlanb028f502008-07-13 14:52:36 +00001994- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1995 the parent module cannot be found while performing an absolute import.
1996 This means that an incorrectly defined __package__ attribute will
1997 now only prevent relative imports in that module rather than causing
1998 all imports from that module to fail.
1999
Nick Coghlan14ff9942008-07-08 14:21:42 +00002000- Issue #2517: Allow unicode messages in Exceptions again by correctly

2010 another thread's dictionary.
2011
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002012- Issue #3004: Minor change to slice.indices(): the start and stop
2013 arguments are now treated identically, making the behaviour easier
2014 to describe and understand. For example, slice(None, -10,
2015 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2016 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2017 10, -1).
2018
Georg Brandl278fc502008-07-19 12:46:12 +00002019- Issue #3219: Calling a function with repeated keyword arguments,
2020 f(a=2, a=23), would not cause a syntax error. This was a regression

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002059- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2060 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002061 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002062 content-length. The problem had been corrected in the 2.4 branch, but never

Ronald Oussoren5640ce22008-06-05 12:58:24 +00002450 environment to control the '-arch' flags that are used to build
2451 an extension. This was added for compatibility with Apple's build
2452 of Python.
2453
2454- The bundled OSX-specific copy of libbffi is now in sync with the version
2455 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
2456
Georg Brandl25c34082008-08-18 23:09:49 +00002457- The threading module gained aliases for names that will be removed in the
2458 3.x series.

2462
Martin v. Löwiscc0f2b22008-06-13 18:12:51 +00002463- The Windows installer now includes Tk 8.5, bzip2 1.0.5, and SQLite 3.5.9.
Martin v. Löwis76307312008-06-12 18:52:00 +00002464
Martin v. Löwis8c255e42008-05-23 15:06:50 +00002465- Patch #1722225: Support QNX 6.
2466
Brett Cannonb61d8012008-05-11 23:39:04 +00002467- ``Lib/lib-old`` is now added to sys.path.
2468
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002469- On MacOS X it is now possible to install the framework in 64-bit
2470 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002471 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002472
2473 This is controlled by the configure argument ``--with-universal-archs``:
2474
2475 - ``--with-universal-archs=all``: install 4-way universal
2476
2477 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2478
2479 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2480
2481 This option should be used in combination with ``--enable-universalsdk=``.
2482
2483 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

2491- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00002492
2493- The PyString functions have been renamed to PyBytes. A batch of
2494 defines were added so that the linker still sees the original
2495 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002533- Issue #1631171: Re-implement the 'warnings' module in C (the
2534 original Python code has been kept as backup). This will allow for
2535 using the 'warning's machinery in such places as the parser where
2536 use of pure Python code is not possible. Both the ``showarning()``
2537 and ``formatwarning()`` gain an optional 'line' argument which is
2538 not called by default for backwards-compatibility reasons. Setting
2539 ``warnings.showwarning()`` to an implementation that lacks support
2540 for the ``line`` argument will raise a DeprecationWarning.

2564
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002565- The getpass module has been improved on Unix. It now uses /dev/tty
2566 by default and uses stderr instead of stdout. A GetPassWarning is
2567 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00002568

Georg Brandl3ee81df2008-05-17 18:14:43 +00002582- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002583 extension modules between 32 and 64 bit platforms. See the distutls

2596 so the controlled environment will more closely mirror the typical
2597 script environment. This supports setup.py scripts that refer to
2598 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002603- Issue #2550: The approach used by client/server code for obtaining
2604 ports to listen on in network-oriented tests has been refined in an
2605 effort to facilitate running multiple instances of the entire
2606 regression test suite in parallel without issue.
2607 test_support.bind_port() has been fixed such that it will always
2608 return a unique port -- which wasn't always the case with the
2609 previous implementation, especially if socket options had been set
2610 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2611 new implementation of bind_port() will actually raise an exception
2612 if it is passed an AF_INET/SOCK_STREAM socket with either the
2613 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2614 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2615 the socket it's been passed. This currently only applies to
2616 Windows. This option prevents any other sockets from binding to the
2617 host/port we've bound to, thus removing the possibility of the
2618 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2619 when a second SOCK_STREAM socket binds and accepts to a host/port
2620 that's already been bound by another socket. The optional preferred
2621 port parameter to bind_port() has been removed. Under no
2622 circumstances should tests be hard coding ports!
2623
2624 test_support.find_unused_port() has also been introduced, which will
2625 pass a temporary socket object to bind_port() in order to obtain an
2626 unused port. The temporary socket object is then closed and
2627 deleted, and the port is returned. This method should only be used
2628 for obtaining an unused port in order to pass to an external program
2629 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2630 a parameter to a server-oriented class that doesn't give you direct
2631 access to the underlying socket used.
2632
2633 Finally, test_support.HOST has been introduced, which should be used
2634 for the host argument of any relevant socket calls (i.e. bind and
2635 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002636
2637 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002638 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002639 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2640 test_asynchat and test_socket_ssl.
2641
Georg Brandl3ee81df2008-05-17 18:14:43 +00002642 It is now possible for multiple instances of the regression test
2643 suite to run in parallel without issue.

2910-----------------
2911
Fred Drakea8ee94b2008-03-01 02:45:07 +00002912- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002913 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002918
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002919- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002920 issue 215555 for a discussion.
2921
Eric Smitha73fbe72008-02-23 03:09:44 +00002922- Added the future_builtins module, which contains hex() and oct().
2923 These are the PEP 3127 version of these functions, designed to be
2924 compatible with the hex() and oct() builtins from Python 3.0. They
2925 differ slightly in their output formats from the existing, unchanged
2926 Python 2.6 builtins. The expected usage of the future_builtins
2927 module is:
2928 from future_builtins import hex, oct
2929
Eric Smith7ef40bf2008-02-20 23:34:22 +00002930- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2931 exponents for exponents with absolute value < 100. Follows C99
2932 standard. This is a change on Windows, which would use 3 digits.
2933 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2934 so that any alterations it does to the resulting string will be
2935 available in stringlib/formatter.h (for float.__format__).
2936
Eric Smith5a3c1352008-02-19 13:21:56 +00002937- Implemented PEP 3101, Advanced String Formatting. This adds a new
2938 builtin format(); a format() method for str and unicode; a
2939 __format__() method to object, str, unicode, int, long, float, and
2940 datetime; the class string.Formatter; and the C API
2941 PyObject_Format().
2942
Georg Brandl3ee81df2008-05-17 18:14:43 +00002943- Fixed several potential crashes, all caused by specially crafted
2944 __del__ methods exploiting objects in temporarily inconsistent
2945 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002946
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002947- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002948 prevent a possible crash: an Abstract Base Class would try to access
2949 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002950

2952 real or imaginary part.

2955 in order to allow pymalloc to free more arenas. Python may give back
2956 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002957
Georg Brandl3ee81df2008-05-17 18:14:43 +00002958- Issue #2045: Fix an infinite recursion triggered when printing a
2959 subclass of collections.defaultdict, if its default_factory is set
2960 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002961
Christian Heimesf75dbef2008-02-08 00:11:31 +00002962- Fixed a minor memory leak in dictobject.c. The content of the free
2963 list was not freed on interpreter shutdown.
2964
Georg Brandl5a7eca12010-03-21 19:29:04 +00002965- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00002966 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002967
Georg Brandl3ee81df2008-05-17 18:14:43 +00002968- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2969 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002970 to compact the internal free lists of pre-allocted ints and floats.
2971
Georg Brandl3ee81df2008-05-17 18:14:43 +00002972- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2973 calls. Python expected the return type int but the fork familie
2974 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002975
Georg Brandl3ee81df2008-05-17 18:14:43 +00002976- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2977 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002978
Georg Brandl3ee81df2008-05-17 18:14:43 +00002979- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2980 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002981
Georg Brandl3ee81df2008-05-17 18:14:43 +00002982- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2983 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00002985- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2986 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002987
Georg Brandl3ee81df2008-05-17 18:14:43 +00002988- Patch #1473257: generator objects gain a gi_code attribute. This is
2989 the same object as the func_code attribute of the function that
2990 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002991
Georg Brandl3ee81df2008-05-17 18:14:43 +00002992- Issue #1920: "while 0" statements were completely removed by the
2993 compiler, even in the presence of an "else" clause, which is
2994 supposed to be run when the condition is false. Now the compiler
2995 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002996
Guido van Rossumeead05f2008-01-24 18:21:02 +00002997- A few crashers fixed: weakref_in_del.py (issue #1377858);
2998 loosing_dict_ref.py (issue #1303614, test67.py);
2999 borrowed_ref_[34].py (not in tracker).

Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003001- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003002 suppressed while an extension is loaded by calling SetErrorMode in
3003 dynload_win.c. The error is still reported properly.
3004
Georg Brandl3ee81df2008-05-17 18:14:43 +00003005- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003006 several extension methods and modules do not work without unicode
3007 support.
3008
Georg Brandl26543b12008-01-21 18:36:51 +00003009- Issue #1882: when compiling code from a string, encoding cookies in the
3010 second line of code were not always recognized correctly.
3011
Georg Brandl14404b62008-01-19 19:27:05 +00003012- Issue #1679: "0x" was taken as a valid integer literal.
3013
Georg Brandl6caad7d2008-01-26 14:19:22 +00003014- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003015 added.
3016
Christian Heimesc94e2b52008-01-14 04:13:37 +00003017- sys.float_info / PyFloat_GetInfo: The floating point information
3018 object was converted from a dict to a specialized structseq object.
3019
Georg Brandl3ee81df2008-05-17 18:14:43 +00003020- Patch #1816: Added sys.flags structseq. It exposes the status of
3021 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003022
Georg Brandl3ee81df2008-05-17 18:14:43 +00003023- Objects/structseq.c: Implemented new structseq representation. The
3024 patch makes structseqs (e.g. the return value of os.stat) more
3025 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003026
Georg Brandl3ee81df2008-05-17 18:14:43 +00003027- Patch #1700288: added a type attribute cache that caches method
3028 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003029
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003030- Bug #1776: __import__() no longer accepts filenames on any platform.
3031 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003032
Georg Brandlaed6c662008-01-07 17:25:53 +00003033- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3034
Georg Brandl3ee81df2008-05-17 18:14:43 +00003035- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3036 envvar and sys.dont_write_bytecode attribute. All these can be set
3037 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003038
Georg Brandl3ee81df2008-05-17 18:14:43 +00003039- Improve some exception messages when Windows fails to load an
3040 extension module. Now we get for example '%1 is not a valid Win32
3041 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003042
Georg Brandl3ee81df2008-05-17 18:14:43 +00003043- Bug #1481296: Fixed long(float('nan')) != 0L.

Christian Heimes0a8143f2007-12-18 23:22:54 +00003048- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003049 and INF. float("nan"), float("inf") and float("-inf") now work on
3050 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003051
Georg Brandl3ee81df2008-05-17 18:14:43 +00003052- Compiler now generates simpler and faster code for dictionary
3053 literals. The oparg for BUILD_MAP now indicates an estimated
3054 dictionary size. There is a new opcode, STORE_MAP, for adding
3055 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003084- Patch #1739468: Directories and zipfiles containing a __main__.py
3085 file can now be directly executed by passing their name to the
3086 interpreter. The directory/zipfile is automatically inserted as the
3087 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003089- Issue #1265: Fix a problem with sys.settrace, if the tracing
3090 function uses a generator expression when at the same time the
3091 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003092
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003093- sets and frozensets now have an isdisjoint() method.
3094
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003095- optimize the performance of builtin.sum().
3096
Neal Norwitz44f326e2007-10-05 05:29:17 +00003097- Fix warnings found by the new version of the Coverity checker.
3098
Georg Brandl5a7eca12010-03-21 19:29:04 +00003099- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003100 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3101 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003102
Georg Brandl3ee81df2008-05-17 18:14:43 +00003103- Issue #1686386: Tuple's tp_repr did not take into account the
3104 possibility of having a self-referential tuple, which is possible
3105 from C code. Nor did object's tp_str consider that a type's tp_str
3106 could do something that could lead to an inifinite recursion.
3107 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3108 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003109
Georg Brandl3ee81df2008-05-17 18:14:43 +00003110- Issue #1164: It was possible to trigger deadlock when using the
3111 'print' statement to write to a file since the GIL was not released
3112 as needed. Now PyObject_Print() does the right thing along with
3113 various tp_print implementations of the built-in types and those in
3114 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003115
Georg Brandl3ee81df2008-05-17 18:14:43 +00003116- Issue #1147: Exceptions were directly allowing string exceptions in
3117 their throw() method even though string exceptions no longer
3118 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003119
Georg Brandl3ee81df2008-05-17 18:14:43 +00003120- Issue #1096: Prevent a segfault from getting the repr of a very
3121 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003122
Brett Cannon1e534b52007-09-07 04:18:30 +00003123- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003124 PyObject_Call() never calling back out to Python code to trigger
3125 recursion depth updates/checks. Required the creation of a static
3126 RuntimeError instance in case normalizing an exception put the
3127 recursion check value past its limit. Fixes crashers
3128 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003129
Georg Brandl3ee81df2008-05-17 18:14:43 +00003130- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003143- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003144 __*__ attributes. (Some already existed, e.g., __doc__ and
3145 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003146
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003147- Add -3 option to the interpreter to warn about features that are
3148 deprecated and will be changed/removed in Python 3.0.
3149
Georg Brandl2134e752007-05-21 20:34:16 +00003150- Patch #1686487: you can now pass any mapping after '**' in function
3151 calls.
3152
Collin Winter62903052007-05-18 23:11:24 +00003153- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003154 "except E as target:". This is to provide forwards compatibility
3155 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00003157- Deprecate BaseException.message as per PEP 352.
3158
Georg Brandl3ee81df2008-05-17 18:14:43 +00003159- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003160 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003161
Vinay Sajip8549ce32007-05-06 17:53:37 +00003162- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003163 setting a plain string, ie don't expand to single letter identifiers.
3164
Raymond Hettinger13936692007-04-11 18:40:58 +00003165- Request #1191699: Slices can now be pickled.
3166
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003167- Request #1193128: str.translate() now allows a None argument for
3168 translations that only remove characters without re-mapping the
3169 remaining characters.
3170
Georg Brandl5cb76c12007-03-21 09:00:39 +00003171- Patch #1682205: a TypeError while unpacking an iterable is no longer
3172 masked by a generic one with the message "unpack non-sequence".
3173
Neal Norwitzaa754b72007-03-21 06:39:48 +00003174- Remove unused file Python/fmod.c.
3175
Guido van Rossum143b5642007-03-23 04:58:42 +00003176- Bug #1683368: The object.__init__() and object.__new__() methods are
3177 now stricter in rejecting excess arguments. The only time when
3178 either allows excess arguments is when it is not overridden and the
3179 other one is. For backwards compatibility, when both are
3180 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003181 warning later). Also, type.__init__() insists on the same signature
3182 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003184- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3185 object to complex using its __complex__() method before falling back
3186 to the __float__() method. Therefore, the functions in the cmath
3187 module now can operate on objects that define a __complex__()
3188 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003189
Georg Brandl3ee81df2008-05-17 18:14:43 +00003190- Patch #1623563: allow __class__ assignment for classes with

Georg Brandl871f1bc2007-03-12 13:17:36 +00003209- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003210 its argument, if it exists. If not, it will work like before. This
3211 allows customizing the output of dir() in the presence of a
3212 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00003224- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl4e933132006-09-06 20:05:58 +00003327- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003736 the client's request was successfully received, understood, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00003777 AttributeError instead of an IOError when the server's response

Georg Brandl92a6bae2007-03-13 17:43:32 +00003811- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003812 are set for invalid interpolation sequences that would lead to

3869 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00004262 time so that opening a database previously created with the DB_DUP
4263 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4264 opens. Specifically: dictionary assignment to a DB object will
4265 replace all values for a given key when the database allows
4266 duplicate values. DB users should use DB.put(k, v) when they want
4267 to store duplicates; not DB[k] = v.

4274 characters with ASCII value less than 32. Also, it correctly quotes
4275 dots only if they occur on a single line, as opposed to the previous
4276 behavior of quoting dots if they are the second character of any
4277 line.
