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

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.

72 ASCII with backslashreplace error handler if str(value) failed
73
Mark Dickinson1cdfa5f2010-05-04 14:30:32 +000074- Issue #8567: Fix precedence of signals in Decimal module: when a
75 Decimal operation raises multiple signals and more than one of those
76 signals is trapped, the specification determines the order in which
77 the signals should be handled. In many cases this order wasn't
78 being followed, leading to the wrong Python exception being raised.

Tarek Ziadé68ca24b2010-04-30 12:18:51 +000093 between the build dir and the source dir when looking for "python.h" or
94 "Include".

109 Sridhar Ratnakumar.
110
Antoine Pitrou53d7d062010-04-25 21:55:45 +0000111- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
112 where the method could block indefinitely if called just before the
113 event loop started running. This also fixes the occasional freezes
114 witnessed in test_httpservers.
115
Antoine Pitrouc689d962010-04-24 20:13:37 +0000116- Issue #5103: SSL handshake would ignore the socket timeout and block

129 a non-infinite timeout. Also make that method friendlier with applications
130 wanting to continue using the socket in clear-text mode, by disabling
131 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
132
Antoine Pitrou878602a2010-04-21 19:41:28 +0000133- Issue #8484: Load all ciphers and digest algorithms when initializing

1222 do an explicit seek to the end of file (so that e.g. tell() returns the
1223 file size rather than 0). This is consistent with the behaviour of the
1224 traditional 2.x file object.

1420What's New in Python 2.6.1
1421==========================
1422
1423*Release date: 04-Dec-2008*
1424
1425Core and Builtins
1426-----------------
1427
1428- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1429 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1430 instead of throwing a MemoryError.
1431
1432- Issue #4367: Python would segfault during compiling when the unicodedata
1433 module couldn't be imported and \N escapes were present.
1434
1435- Issue #4348: Some bytearray methods returned that didn't cause any change to
1436 the bytearray, returned the same bytearray instead of a copy.
1437
1438- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1439
1440- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1441
1442- Issue #4048: The parser module now correctly validates relative imports.
1443
1444- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1445 exec statement.
1446
1447- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1448 method does not return iterators for the 4th and 5th items.
1449
1450- Issue #4209: Enabling unicode_literals and the print_function in the same
1451 __future__ import didn't work.
1452
1453- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1454 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1455 really executed because I cannot move to such directory on win2k)
1456
1457- Issue #4069: When set.remove(element) is used with a set element, the element
1458 is temporarily replaced with an equivalent frozenset. But the eventual
1459 KeyError would always report the empty frozenset([]) as the missing key. Now
1460 it correctly refers to the initial element.
1461
1462- Fixed C99 style comments in several files. Python is now C89 compatible
1463 again.

Benjamin Peterson8d77d442008-09-30 01:31:49 +00001581- Security Issue #2: imageop did not validate arguments correctly and could
1582 segfault as a result.
1583
Benjamin Peterson8c2b7dc2008-09-18 01:22:16 +00001584- Issue #3886: Possible integer overflows in the _hashopenssl module were

1590- Issue #3850: recursion tests in Misc/find_recursion_limit.py can raise
1591 AttributeError instead of RuntimeError, depending in which C API call
1592 exactly the recursion limit is exceeded. Consequently, both exception types
1593 are caught and silenced.

1609
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001610- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1611
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001612- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1613 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1614 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1615 ``printf`` function, whereas PyString_FromFormat has an independent
1616 implementation and uses "%zd" on all platforms for size_t values.
1617 This makes a difference on win64, where ``printf`` needs "%Id" to display
1618 64bit values.
1619
Benjamin Peterson97179b02008-09-09 20:55:01 +00001620- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1621 error.
1622
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001623- Issue #3777: long() applied to a float object now always return a long
1624 object; previously an int would be returned for small values. the __long__
1625 method is allowed to return either an int or a long, but the behaviour of
1626 float objects should not change to respect backward compatibility.
1627
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001628- Issue #3751: str.rpartition would perform a left-partition when called with
1629 a unicode argument.
1630
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001631- Issue #3683: Fix compilation when --without-threads is given.
1632
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001633- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001634 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001635 was correctly parsed but parsing of subsequent arguments failed.
1636
Vinay Sajip35e3b032008-09-01 14:33:59 +00001637- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001638 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1639 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1640 when given a tuple of classes as second argument, were looking up
1641 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1642 type object.
1643
Neal Norwitz18aa3882008-08-24 05:04:52 +00001644- Fix crashes on memory allocation failure found with failmalloc.
1645
1646- Fix memory leaks found with valgrind and update suppressions file.
1647
1648- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1649
1650- Fix problem using wrong name in decimal module reported by pychecker.
1651
Christian Heimes7d4c3172008-08-22 19:47:25 +00001652- Silenced another compiler warning about a used but not defined
1653 function 'stringlib_contains_obj'.

1656 ``__delslice__``.
1657
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00001658- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
1659 library targets in the Makefile.
1660
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001661- Issue #1204: The configure script now tests for additional libraries
1662 that may be required when linking against readline. This fixes issues
1663 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

1679
Nick Coghland2e09382008-09-11 12:11:06 +00001680- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
1681 silent misbehaviour when a single instance is nested in multiple
1682 with statements, or when the methods are invoked in the wrong order.
1683
Vinay Sajip844f7412008-09-09 13:42:08 +00001684- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.
1685
Nick Coghland2e09382008-09-11 12:11:06 +00001686- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001687 return a list or None rather than a custom object.
1688
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00001689- Issue #1638033: Cookie.Morsel gained the httponly attribute.

1713 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1714 for catch_warnings() also led to an improvement in the raising of a
1715 DeprecationWarning related to warnings.warn_explicit().
1716
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001717- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001778What's New in Python 2.6 beta 3?
1779================================

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001782
1783Core and Builtins
1784-----------------
1785
Guido van Rossumf8402962008-08-20 15:01:50 +00001786- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1787 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1788 extensions do not automatically benefit from the class attribute
1789 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1790 to their tp_flags field if they care. This is a backwards
1791 compatibility feature; in 3.0, all types will use the cache by
1792 default.
1793
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001794- Keyword arguments can now follow starred arguments. (``f(a, *args,
1795 keyword=23)`` is now valid syntax.)
1796
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001797- ctypes function pointers that are COM methods have a boolean True
1798 value again.
1799
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001800- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1801 by denying s# to parse objects that have a releasebuffer procedure,
1802 and introducing s*.
1803
Georg Brandl1e13ea92008-08-11 09:07:59 +00001804- Issue #3537: Fix an assertion failure when an empty but presized dict
1805 object was stored in the freelist.
1806
Mark Dickinsonb6467572008-08-04 21:30:09 +00001807- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1808 ValueError consistently across platforms.
1809
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001810- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1811 (64bit Unix, for example), unichr() would truncate its argument and return
1812 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1813
Neal Norwitze7d8be82008-07-31 17:17:14 +00001814- Apply security patches from Apple.
1815
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001816- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1817 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1818
Antoine Pitrou92f82162008-07-25 22:22:08 +00001819- Issue #1819: function calls with several named parameters are now on
1820 average 35% faster (as measured by pybench).
1821
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001822- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1823 the python debugger steps into a class statement: the free variables (local
1824 variables defined in an outer scope) would be deleted from the outer scope.
1825
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001826- Issue #2620: Overflow checking when allocating or reallocating memory
1827 was not always being done properly in some python types and extension
1828 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1829 all been updated to perform better checks and places in the code that
1830 would previously leak memory on the error path when such an allocation
1831 failed have been fixed.

1837
Benjamin Petersone977ad42008-08-20 01:42:01 +00001838- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1839 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1840
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001841- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1842 version reported by these tools does not necessarily follow the python
1843 version numbering scheme, so the module is less strict when parsing it.
1844
Nick Coghlanf70385a2008-08-18 12:42:46 +00001845- Issue #2235: Added Py3k warnings for types which will become unhashable
1846 under the stricter __hash__ inheritance rules in 3.0. Several types
1847 which did not meet the rules for hash invariants and were already
1848 unhashable in 3.0 have now been explicitly flagged as unhashable in
1849 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1850 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1851
Brett Cannon88f801d2008-08-18 00:46:22 +00001852- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1853 imported into the module but exposed as part of the module's API.
1854
Brett Cannon7b96f072008-08-18 00:41:11 +00001855- Remove an unneeded import of abc.ABCMeta from 'inspect'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001859- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1860
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001861- Issue #3575: Incremental decoder's decode function now takes bytearray
1862 by using 's*' instead of 't#'.
1863
Jesus Cea585ad8a2009-07-02 15:37:21 +00001864- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001865 fails unicode conversion on 2nd parameter. (windows only)
1866

Antoine Pitroude781a42008-08-09 12:43:23 +00001921 asking for a specific length. This problem only affected files opened

1978-----------------
1979
Georg Brandl3e483f62008-07-16 22:57:41 +00001980- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1981 its methods now allow for items objects that can be converted to
1982 an integer using operator.index().
1983
Mark Dickinson64b7e502008-07-16 09:40:03 +00001984- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1985 produced a ValueError instead of giving the correct float.
1986
Eric Smitha5fa5a22008-07-16 00:11:49 +00001987- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1988 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1989
Mark Dickinson7103aa42008-07-15 19:08:33 +00001990- Issue #3008: the float type has a new instance method 'float.hex'
1991 and a new class method 'float.fromhex' to convert floating-point
1992 numbers to and from hexadecimal strings, respectively.
1993
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001994- Issue #2235: __hash__ is once again inherited by default. To allow
1995 collections.Hashable to remain meaningful in the presence of the
1996 default hash implementation (object.__hash__), it is now possible
1997 to explicit block inheritance of hash by setting __hash__=None at
1998 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1999 level.
2000
Nick Coghlanb028f502008-07-13 14:52:36 +00002001- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2002 the parent module cannot be found while performing an absolute import.
2003 This means that an incorrectly defined __package__ attribute will
2004 now only prevent relative imports in that module rather than causing
2005 all imports from that module to fail.
2006
Nick Coghlan14ff9942008-07-08 14:21:42 +00002007- Issue #2517: Allow unicode messages in Exceptions again by correctly

2017 another thread's dictionary.
2018
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002019- Issue #3004: Minor change to slice.indices(): the start and stop
2020 arguments are now treated identically, making the behaviour easier
2021 to describe and understand. For example, slice(None, -10,
2022 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2023 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2024 10, -1).
2025
Georg Brandl278fc502008-07-19 12:46:12 +00002026- Issue #3219: Calling a function with repeated keyword arguments,
2027 f(a=2, a=23), would not cause a syntax error. This was a regression
2028 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002066- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2067 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002068 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002069 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002085- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Brett Cannonb61d8012008-05-11 23:39:04 +00002474- ``Lib/lib-old`` is now added to sys.path.
2475
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002476- On MacOS X it is now possible to install the framework in 64-bit
2477 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002478 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002479
2480 This is controlled by the configure argument ``--with-universal-archs``:
2481
2482 - ``--with-universal-archs=all``: install 4-way universal
2483
2484 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2485
2486 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2487
2488 This option should be used in combination with ``--enable-universalsdk=``.
2489
2490 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00002540- Issue #1631171: Re-implement the 'warnings' module in C (the
2541 original Python code has been kept as backup). This will allow for
2542 using the 'warning's machinery in such places as the parser where
2543 use of pure Python code is not possible. Both the ``showarning()``
2544 and ``formatwarning()`` gain an optional 'line' argument which is
2545 not called by default for backwards-compatibility reasons. Setting
2546 ``warnings.showwarning()`` to an implementation that lacks support
2547 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002572- The getpass module has been improved on Unix. It now uses /dev/tty
2573 by default and uses stderr instead of stdout. A GetPassWarning is
2574 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002589- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002590 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002610- Issue #2550: The approach used by client/server code for obtaining
2611 ports to listen on in network-oriented tests has been refined in an
2612 effort to facilitate running multiple instances of the entire
2613 regression test suite in parallel without issue.
2614 test_support.bind_port() has been fixed such that it will always
2615 return a unique port -- which wasn't always the case with the
2616 previous implementation, especially if socket options had been set
2617 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2618 new implementation of bind_port() will actually raise an exception
2619 if it is passed an AF_INET/SOCK_STREAM socket with either the
2620 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2621 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2622 the socket it's been passed. This currently only applies to
2623 Windows. This option prevents any other sockets from binding to the
2624 host/port we've bound to, thus removing the possibility of the
2625 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2626 when a second SOCK_STREAM socket binds and accepts to a host/port
2627 that's already been bound by another socket. The optional preferred
2628 port parameter to bind_port() has been removed. Under no
2629 circumstances should tests be hard coding ports!
2630
2631 test_support.find_unused_port() has also been introduced, which will
2632 pass a temporary socket object to bind_port() in order to obtain an
2633 unused port. The temporary socket object is then closed and
2634 deleted, and the port is returned. This method should only be used
2635 for obtaining an unused port in order to pass to an external program
2636 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2637 a parameter to a server-oriented class that doesn't give you direct
2638 access to the underlying socket used.
2639
2640 Finally, test_support.HOST has been introduced, which should be used
2641 for the host argument of any relevant socket calls (i.e. bind and
2642 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002643
2644 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002645 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002646 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2647 test_asynchat and test_socket_ssl.
2648
Georg Brandl3ee81df2008-05-17 18:14:43 +00002649 It is now possible for multiple instances of the regression test
2650 suite to run in parallel without issue.

2917-----------------
2918
Fred Drakea8ee94b2008-03-01 02:45:07 +00002919- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002920 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002925
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002926- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002927 issue 215555 for a discussion.
2928
Eric Smitha73fbe72008-02-23 03:09:44 +00002929- Added the future_builtins module, which contains hex() and oct().
2930 These are the PEP 3127 version of these functions, designed to be
2931 compatible with the hex() and oct() builtins from Python 3.0. They
2932 differ slightly in their output formats from the existing, unchanged
2933 Python 2.6 builtins. The expected usage of the future_builtins
2934 module is:
2935 from future_builtins import hex, oct
2936
Eric Smith7ef40bf2008-02-20 23:34:22 +00002937- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2938 exponents for exponents with absolute value < 100. Follows C99
2939 standard. This is a change on Windows, which would use 3 digits.
2940 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2941 so that any alterations it does to the resulting string will be
2942 available in stringlib/formatter.h (for float.__format__).
2943
Eric Smith5a3c1352008-02-19 13:21:56 +00002944- Implemented PEP 3101, Advanced String Formatting. This adds a new
2945 builtin format(); a format() method for str and unicode; a
2946 __format__() method to object, str, unicode, int, long, float, and
2947 datetime; the class string.Formatter; and the C API
2948 PyObject_Format().
2949
Georg Brandl3ee81df2008-05-17 18:14:43 +00002950- Fixed several potential crashes, all caused by specially crafted
2951 __del__ methods exploiting objects in temporarily inconsistent
2952 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002953
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002954- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002955 prevent a possible crash: an Abstract Base Class would try to access
2956 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002957
Georg Brandl3ee81df2008-05-17 18:14:43 +00002958- Fixed repr() and str() of complex numbers with infinity or nan as
2959 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002960
Georg Brandl3ee81df2008-05-17 18:14:43 +00002961- Clear all free lists during a gc.collect() of the highest generation
2962 in order to allow pymalloc to free more arenas. Python may give back
2963 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002964
Georg Brandl3ee81df2008-05-17 18:14:43 +00002965- Issue #2045: Fix an infinite recursion triggered when printing a
2966 subclass of collections.defaultdict, if its default_factory is set
2967 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002968
Christian Heimesf75dbef2008-02-08 00:11:31 +00002969- Fixed a minor memory leak in dictobject.c. The content of the free
2970 list was not freed on interpreter shutdown.
2971
Georg Brandl5a7eca12010-03-21 19:29:04 +00002972- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00002973 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002974
Georg Brandl3ee81df2008-05-17 18:14:43 +00002975- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2976 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002977 to compact the internal free lists of pre-allocted ints and floats.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002995- Patch #1473257: generator objects gain a gi_code attribute. This is
2996 the same object as the func_code attribute of the function that
2997 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002998
Georg Brandl3ee81df2008-05-17 18:14:43 +00002999- Issue #1920: "while 0" statements were completely removed by the
3000 compiler, even in the presence of an "else" clause, which is
3001 supposed to be run when the condition is false. Now the compiler
3002 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003003
Guido van Rossumeead05f2008-01-24 18:21:02 +00003004- A few crashers fixed: weakref_in_del.py (issue #1377858);
3005 loosing_dict_ref.py (issue #1303614, test67.py);
3006 borrowed_ref_[34].py (not in tracker).
3007
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003008- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003009 suppressed while an extension is loaded by calling SetErrorMode in
3010 dynload_win.c. The error is still reported properly.
3011
Georg Brandl3ee81df2008-05-17 18:14:43 +00003012- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003013 several extension methods and modules do not work without unicode
3014 support.
3015
Georg Brandl26543b12008-01-21 18:36:51 +00003016- Issue #1882: when compiling code from a string, encoding cookies in the

3018
Georg Brandl14404b62008-01-19 19:27:05 +00003019- Issue #1679: "0x" was taken as a valid integer literal.
3020
Georg Brandl6caad7d2008-01-26 14:19:22 +00003021- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003022 added.
3023
Christian Heimesc94e2b52008-01-14 04:13:37 +00003024- sys.float_info / PyFloat_GetInfo: The floating point information
3025 object was converted from a dict to a specialized structseq object.
3026
Georg Brandl3ee81df2008-05-17 18:14:43 +00003027- Patch #1816: Added sys.flags structseq. It exposes the status of
3028 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003029
Georg Brandl3ee81df2008-05-17 18:14:43 +00003030- Objects/structseq.c: Implemented new structseq representation. The
3031 patch makes structseqs (e.g. the return value of os.stat) more
3032 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003033
Georg Brandl3ee81df2008-05-17 18:14:43 +00003034- Patch #1700288: added a type attribute cache that caches method
3035 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003036
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003037- Bug #1776: __import__() no longer accepts filenames on any platform.
3038 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003039
Georg Brandlaed6c662008-01-07 17:25:53 +00003040- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3041
Georg Brandl3ee81df2008-05-17 18:14:43 +00003042- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3043 envvar and sys.dont_write_bytecode attribute. All these can be set
3044 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003045
Georg Brandl3ee81df2008-05-17 18:14:43 +00003046- Improve some exception messages when Windows fails to load an
3047 extension module. Now we get for example '%1 is not a valid Win32
3048 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003049

Christian Heimes0a8143f2007-12-18 23:22:54 +00003055- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003056 and INF. float("nan"), float("inf") and float("-inf") now work on
3057 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003058
Georg Brandl3ee81df2008-05-17 18:14:43 +00003059- Compiler now generates simpler and faster code for dictionary
3060 literals. The oparg for BUILD_MAP now indicates an estimated
3061 dictionary size. There is a new opcode, STORE_MAP, for adding
3062 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003091- Patch #1739468: Directories and zipfiles containing a __main__.py
3092 file can now be directly executed by passing their name to the
3093 interpreter. The directory/zipfile is automatically inserted as the
3094 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003096- Issue #1265: Fix a problem with sys.settrace, if the tracing
3097 function uses a generator expression when at the same time the
3098 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003099
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003100- sets and frozensets now have an isdisjoint() method.
3101

3103
Neal Norwitz44f326e2007-10-05 05:29:17 +00003104- Fix warnings found by the new version of the Coverity checker.
3105
Georg Brandl5a7eca12010-03-21 19:29:04 +00003106- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003107 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3108 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003109
Georg Brandl3ee81df2008-05-17 18:14:43 +00003110- Issue #1686386: Tuple's tp_repr did not take into account the
3111 possibility of having a self-referential tuple, which is possible
3112 from C code. Nor did object's tp_str consider that a type's tp_str
3113 could do something that could lead to an inifinite recursion.
3114 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3115 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003116
Georg Brandl3ee81df2008-05-17 18:14:43 +00003117- Issue #1164: It was possible to trigger deadlock when using the
3118 'print' statement to write to a file since the GIL was not released
3119 as needed. Now PyObject_Print() does the right thing along with
3120 various tp_print implementations of the built-in types and those in
3121 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003122
Georg Brandl3ee81df2008-05-17 18:14:43 +00003123- Issue #1147: Exceptions were directly allowing string exceptions in
3124 their throw() method even though string exceptions no longer
3125 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003126
Georg Brandl3ee81df2008-05-17 18:14:43 +00003127- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannona0c05512007-09-10 21:38:27 +00003129
Brett Cannon1e534b52007-09-07 04:18:30 +00003130- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003131 PyObject_Call() never calling back out to Python code to trigger
3132 recursion depth updates/checks. Required the creation of a static
3133 RuntimeError instance in case normalizing an exception put the
3134 recursion check value past its limit. Fixes crashers
3135 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003136

Neal Norwitz0ac60192007-05-27 04:08:54 +00003150- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003151 __*__ attributes. (Some already existed, e.g., __doc__ and
3152 __name__.)

3156
Georg Brandl2134e752007-05-21 20:34:16 +00003157- Patch #1686487: you can now pass any mapping after '**' in function
3158 calls.
3159
Collin Winter62903052007-05-18 23:11:24 +00003160- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003161 "except E as target:". This is to provide forwards compatibility
3162 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00003169- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003170 setting a plain string, ie don't expand to single letter identifiers.
3171
Raymond Hettinger13936692007-04-11 18:40:58 +00003172- Request #1191699: Slices can now be pickled.
3173
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003174- Request #1193128: str.translate() now allows a None argument for
3175 translations that only remove characters without re-mapping the
3176 remaining characters.
3177
Georg Brandl5cb76c12007-03-21 09:00:39 +00003178- Patch #1682205: a TypeError while unpacking an iterable is no longer
3179 masked by a generic one with the message "unpack non-sequence".
3180
Neal Norwitzaa754b72007-03-21 06:39:48 +00003181- Remove unused file Python/fmod.c.
3182
Guido van Rossum143b5642007-03-23 04:58:42 +00003183- Bug #1683368: The object.__init__() and object.__new__() methods are
3184 now stricter in rejecting excess arguments. The only time when
3185 either allows excess arguments is when it is not overridden and the
3186 other one is. For backwards compatibility, when both are
3187 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003188 warning later). Also, type.__init__() insists on the same signature
3189 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003191- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3192 object to complex using its __complex__() method before falling back
3193 to the __float__() method. Therefore, the functions in the cmath
3194 module now can operate on objects that define a __complex__()
3195 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003196

Georg Brandl3ee81df2008-05-17 18:14:43 +00003217 its argument, if it exists. If not, it will work like before. This
3218 allows customizing the output of dir() in the presence of a

Georg Brandlaa2321b2007-03-07 00:40:28 +00003231- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl2c1375c2006-10-12 11:27:59 +00003301- Bug #1545497: when given an explicit base, int() did ignore NULs
3302 embedded in the string to convert.
3303
Georg Brandl846f73a2006-10-08 07:11:54 +00003304- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00003352 generator expressions (x for x, in ... ) works again. Fixing this
3353 problem required changing the .pyc magic number. This means that

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004167 that the SMTP.starttls() caller no longer needs to call ehlo()
4168 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004169 does not claim to support starttls. Adds the
4170 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4171 Fenner.

4251 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4252 silently miscode subclasses of those types. Now, it raises a
4253 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004254

Georg Brandl3ee81df2008-05-17 18:14:43 +00004269 time so that opening a database previously created with the DB_DUP
4270 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4271 opens. Specifically: dictionary assignment to a DB object will
4272 replace all values for a given key when the database allows
4273 duplicate values. DB users should use DB.put(k, v) when they want
4274 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004275

4281 characters with ASCII value less than 32. Also, it correctly quotes
4282 dots only if they occur on a single line, as opposed to the previous
4283 behavior of quoting dots if they are the second character of any
4284 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004285
