1270What's New in Python 2.6.1
1271==========================
1272
1273*Release date: 04-Dec-2008*
1274
1275Core and Builtins
1276-----------------
1277
1278- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1279 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1280 instead of throwing a MemoryError.
1281
1282- Issue #4367: Python would segfault during compiling when the unicodedata
1283 module couldn't be imported and \N escapes were present.
1284
1285- Issue #4348: Some bytearray methods returned that didn't cause any change to
1286 the bytearray, returned the same bytearray instead of a copy.
1287
1288- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1289
1290- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1291
1292- Issue #4048: The parser module now correctly validates relative imports.
1293
1294- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1295 exec statement.
1296
1297- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1298 method does not return iterators for the 4th and 5th items.
1299
1300- Issue #4209: Enabling unicode_literals and the print_function in the same
1301 __future__ import didn't work.
1302
1303- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1304 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1305 really executed because I cannot move to such directory on win2k)
1306
1307- Issue #4069: When set.remove(element) is used with a set element, the element
1308 is temporarily replaced with an equivalent frozenset. But the eventual
1309 KeyError would always report the empty frozenset([]) as the missing key. Now
1310 it correctly refers to the initial element.
1311
1312- Fixed C99 style comments in several files. Python is now C89 compatible
1313 again.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001460- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1461
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001462- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1463 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1464 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1465 ``printf`` function, whereas PyString_FromFormat has an independent
1466 implementation and uses "%zd" on all platforms for size_t values.
1467 This makes a difference on win64, where ``printf`` needs "%Id" to display
1468 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001470- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Vinay Sajip35e3b032008-09-01 14:33:59 +00001487- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001488 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1489 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1490 when given a tuple of classes as second argument, were looking up
1491 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1492 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001628What's New in Python 2.6 beta 3?
1629================================
1630
Barry Warsaw07a4a382008-08-21 01:15:08 +00001631*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001632
1633Core and Builtins
1634-----------------
1635
Guido van Rossumf8402962008-08-20 15:01:50 +00001636- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1637 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1638 extensions do not automatically benefit from the class attribute
1639 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1640 to their tp_flags field if they care. This is a backwards
1641 compatibility feature; in 3.0, all types will use the cache by
1642 default.
1643
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001644- Keyword arguments can now follow starred arguments. (``f(a, *args,
1645 keyword=23)`` is now valid syntax.)
1646
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001647- ctypes function pointers that are COM methods have a boolean True
1648 value again.
1649
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001650- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1651 by denying s# to parse objects that have a releasebuffer procedure,
1652 and introducing s*.
1653
Georg Brandl1e13ea92008-08-11 09:07:59 +00001654- Issue #3537: Fix an assertion failure when an empty but presized dict
1655 object was stored in the freelist.
1656
Mark Dickinsonb6467572008-08-04 21:30:09 +00001657- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1658 ValueError consistently across platforms.
1659
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001660- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1661 (64bit Unix, for example), unichr() would truncate its argument and return
1662 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1663
Neal Norwitze7d8be82008-07-31 17:17:14 +00001664- Apply security patches from Apple.
1665
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001666- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1667 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1668
Antoine Pitrou92f82162008-07-25 22:22:08 +00001669- Issue #1819: function calls with several named parameters are now on
1670 average 35% faster (as measured by pybench).
1671
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001672- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1673 the python debugger steps into a class statement: the free variables (local
1674 variables defined in an outer scope) would be deleted from the outer scope.
1675
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001676- Issue #2620: Overflow checking when allocating or reallocating memory
1677 was not always being done properly in some python types and extension
1678 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1679 all been updated to perform better checks and places in the code that
1680 would previously leak memory on the error path when such an allocation
1681 failed have been fixed.
1682
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001683Library
1684-------
1685
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001686- Issue #3612: Added some missing basic types in ctypes.wintypes.
1687
Benjamin Petersone977ad42008-08-20 01:42:01 +00001688- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1689 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1690
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001691- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1692 version reported by these tools does not necessarily follow the python
1693 version numbering scheme, so the module is less strict when parsing it.
1694
Nick Coghlanf70385a2008-08-18 12:42:46 +00001695- Issue #2235: Added Py3k warnings for types which will become unhashable
1696 under the stricter __hash__ inheritance rules in 3.0. Several types
1697 which did not meet the rules for hash invariants and were already
1698 unhashable in 3.0 have now been explicitly flagged as unhashable in
1699 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1700 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1701
Brett Cannon88f801d2008-08-18 00:46:22 +00001702- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1703 imported into the module but exposed as part of the module's API.
1704
Brett Cannon7b96f072008-08-18 00:41:11 +00001705- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1706
Brett Cannon46225e72008-08-18 00:36:52 +00001707- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1708
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001709- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1710
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001711- Issue #3575: Incremental decoder's decode function now takes bytearray
1712 by using 's*' instead of 't#'.
1713
Jesus Cea585ad8a2009-07-02 15:37:21 +00001714- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001715 fails unicode conversion on 2nd parameter. (windows only)
1716
Facundo Batista94f243a2008-08-17 03:38:39 +00001717- Issue 2464. urllib2 now supports a malformation in the URL received
1718 in a redirect.
1719
Brett Cannonabe423e2008-08-16 21:47:07 +00001720- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001721 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001722
Facundo Batistaeb90b782008-08-16 14:44:07 +00001723- Issue #2776: fixed small issue when handling an URL with double slash
1724 after a 302 response in the case of not going through a proxy.
1725
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001726- Issue #2676: in the email package, content-type parsing was hanging on
1727 pathological input because of quadratic or exponential behaviour of a
1728 regular expression.
1729
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001730- Issue #3476: binary buffered reading through the new "io" library is now
1731 thread-safe.
1732
Brett Cannonbf3157b2008-08-14 05:00:03 +00001733- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1734 since mimetools itself is deprecated. Because modules are cached, all
1735 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1736
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001737- Issue #3134: shutil referenced undefined WindowsError symbol.
1738
Robert Schuppenies14646332008-08-10 11:01:53 +00001739- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1740 menu entries were not deleted.
1741
Brett Cannon83e81842008-08-09 23:30:55 +00001742- Copied the implementation of reduce() to _functools.reduce() to have a
1743 version that did not raise a DeprecationWarning under -3.
1744
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001745- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1746 a MemoryError rather than silently stop the iteration.
1747
Guido van Rossum59ce9012008-08-09 14:55:34 +00001748- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1749 to _sre.compile() will now be rejected. This should not affect anybody
1750 since the re.compile() function never generates invalid re-bytecode.
1751
Skip Montanaroa032bf42008-08-08 22:52:51 +00001752- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1753 upon first access it can be automatically initialized from the csv file if
1754 it wasn't initialized during instantiation.
1755
Brett Cannon3aa2a492008-08-06 22:28:09 +00001756- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1757 the reload() built-in has been removed.
1758
Brett Cannon7e30b672008-08-04 21:52:25 +00001759- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001760 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1763 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
1764 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1765 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00001766
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001767- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1768 raised an AttributeError.
1769
Benjamin Peterson01a24322008-07-28 23:35:27 +00001770- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001771 asking for a specific length. This problem only affected files opened
1772 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001773
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001774- Issue #3449: Update decimal module to use most recent specification
1775 (v. 1.68) and tests (v. 2.58) from IBM.
1776
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001777- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
1778

1785
1786- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1787 invalid arguments.
1788
1789- Issue #3302: Fix several crashes when calling locale's gettext functions
1790 with None arguments.
1791
1792- Issue #3389: Allow resolving dotted names for handlers in logging
1793 configuration files.
1794
1795- Deprecate the sunaudio module for removal in Python 3.0.
1796
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001797- Issue #3394: zipfile.writestr sets external attributes when passed a
1798 file name rather than a ZipInfo instance, so files are extracted with
1799 mode 0600 rather than 000 under Unix.
1800
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001801- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1802 argument in python 2.5, this broke code that subclassed Popen to include its
1803 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1811-------------
1812
Nick Coghlan6e8fef02008-08-18 13:14:22 +00001813- Issue #2235: the C API function PyObject_HashNotImplemented and its
1814 interaction with the tp_hash slot (added in 2.6b2) are now documented
1815
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001816- Issue #643841: The language reference now provides more detailed
1817 coverage of the lookup process for special methods. The disclaimers
1818 regarding lack of coverage of new-style classes have also been
1819 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001822What's New in Python 2.6 beta 2?
1823================================
1824
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001825*Release date: 17-Jul-2008*
1826
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001827Core and Builtins
1828-----------------
1829
Georg Brandl3e483f62008-07-16 22:57:41 +00001830- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1831 its methods now allow for items objects that can be converted to
1832 an integer using operator.index().
1833
Mark Dickinson64b7e502008-07-16 09:40:03 +00001834- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1835 produced a ValueError instead of giving the correct float.
1836
Eric Smitha5fa5a22008-07-16 00:11:49 +00001837- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1838 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1839
Mark Dickinson7103aa42008-07-15 19:08:33 +00001840- Issue #3008: the float type has a new instance method 'float.hex'
1841 and a new class method 'float.fromhex' to convert floating-point
1842 numbers to and from hexadecimal strings, respectively.
1843
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001844- Issue #2235: __hash__ is once again inherited by default. To allow
1845 collections.Hashable to remain meaningful in the presence of the
1846 default hash implementation (object.__hash__), it is now possible
1847 to explicit block inheritance of hash by setting __hash__=None at
1848 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1849 level.
1850
Nick Coghlanb028f502008-07-13 14:52:36 +00001851- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1852 the parent module cannot be found while performing an absolute import.
1853 This means that an incorrectly defined __package__ attribute will
1854 now only prevent relative imports in that module rather than causing
1855 all imports from that module to fail.
1856
Nick Coghlan14ff9942008-07-08 14:21:42 +00001857- Issue #2517: Allow unicode messages in Exceptions again by correctly
1858 bypassing the instance dictionary when looking up __unicode__ on
1859 new-style classes.
1860
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001861- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1862 set to a custom object whose write() method happens to install
1863 another file in sys.stdout.
1864
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001865- Issue #3088: Corrected a race condition in classes derived from
1866 threading.local: the first member set by a thread could be saved in
1867 another thread's dictionary.
1868
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001869- Issue #3004: Minor change to slice.indices(): the start and stop
1870 arguments are now treated identically, making the behaviour easier
1871 to describe and understand. For example, slice(None, -10,
1872 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1873 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1874 10, -1).
1875
Georg Brandl278fc502008-07-19 12:46:12 +00001876- Issue #3219: Calling a function with repeated keyword arguments,
1877 f(a=2, a=23), would not cause a syntax error. This was a regression
1878 from 2.4 caused by the switch to the new compiler.

2377 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002390- Issue #1631171: Re-implement the 'warnings' module in C (the
2391 original Python code has been kept as backup). This will allow for
2392 using the 'warning's machinery in such places as the parser where
2393 use of pure Python code is not possible. Both the ``showarning()``
2394 and ``formatwarning()`` gain an optional 'line' argument which is
2395 not called by default for backwards-compatibility reasons. Setting
2396 ``warnings.showwarning()`` to an implementation that lacks support
2397 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002460- Issue #2550: The approach used by client/server code for obtaining
2461 ports to listen on in network-oriented tests has been refined in an
2462 effort to facilitate running multiple instances of the entire
2463 regression test suite in parallel without issue.
2464 test_support.bind_port() has been fixed such that it will always
2465 return a unique port -- which wasn't always the case with the
2466 previous implementation, especially if socket options had been set
2467 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2468 new implementation of bind_port() will actually raise an exception
2469 if it is passed an AF_INET/SOCK_STREAM socket with either the
2470 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2471 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2472 the socket it's been passed. This currently only applies to
2473 Windows. This option prevents any other sockets from binding to the
2474 host/port we've bound to, thus removing the possibility of the
2475 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2476 when a second SOCK_STREAM socket binds and accepts to a host/port
2477 that's already been bound by another socket. The optional preferred
2478 port parameter to bind_port() has been removed. Under no
2479 circumstances should tests be hard coding ports!
2480
2481 test_support.find_unused_port() has also been introduced, which will
2482 pass a temporary socket object to bind_port() in order to obtain an
2483 unused port. The temporary socket object is then closed and
2484 deleted, and the port is returned. This method should only be used
2485 for obtaining an unused port in order to pass to an external program
2486 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2487 a parameter to a server-oriented class that doesn't give you direct
2488 access to the underlying socket used.
2489
2490 Finally, test_support.HOST has been introduced, which should be used
2491 for the host argument of any relevant socket calls (i.e. bind and
2492 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002493
2494 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002495 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002496 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2497 test_asynchat and test_socket_ssl.
2498
Georg Brandl3ee81df2008-05-17 18:14:43 +00002499 It is now possible for multiple instances of the regression test
2500 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002706 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
2707 files are used. On all linux systems the --with-system-ffi
2708 configure option defaults to "yes".

2768
Fred Drakea8ee94b2008-03-01 02:45:07 +00002769- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002770 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00002772- Issue #2067: file.__exit__() now calls subclasses' close() method.
2773
2774- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002775
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002776- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002777 issue 215555 for a discussion.
2778
Eric Smitha73fbe72008-02-23 03:09:44 +00002779- Added the future_builtins module, which contains hex() and oct().
2780 These are the PEP 3127 version of these functions, designed to be
2781 compatible with the hex() and oct() builtins from Python 3.0. They
2782 differ slightly in their output formats from the existing, unchanged
2783 Python 2.6 builtins. The expected usage of the future_builtins
2784 module is:
2785 from future_builtins import hex, oct
2786
Eric Smith7ef40bf2008-02-20 23:34:22 +00002787- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2788 exponents for exponents with absolute value < 100. Follows C99
2789 standard. This is a change on Windows, which would use 3 digits.
2790 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2791 so that any alterations it does to the resulting string will be
2792 available in stringlib/formatter.h (for float.__format__).
2793
Eric Smith5a3c1352008-02-19 13:21:56 +00002794- Implemented PEP 3101, Advanced String Formatting. This adds a new
2795 builtin format(); a format() method for str and unicode; a
2796 __format__() method to object, str, unicode, int, long, float, and
2797 datetime; the class string.Formatter; and the C API
2798 PyObject_Format().
2799
Georg Brandl3ee81df2008-05-17 18:14:43 +00002800- Fixed several potential crashes, all caused by specially crafted
2801 __del__ methods exploiting objects in temporarily inconsistent
2802 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002803
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002804- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002805 prevent a possible crash: an Abstract Base Class would try to access
2806 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002807
Georg Brandl3ee81df2008-05-17 18:14:43 +00002808- Fixed repr() and str() of complex numbers with infinity or nan as
2809 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002811- Clear all free lists during a gc.collect() of the highest generation
2812 in order to allow pymalloc to free more arenas. Python may give back
2813 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002814
Georg Brandl3ee81df2008-05-17 18:14:43 +00002815- Issue #2045: Fix an infinite recursion triggered when printing a
2816 subclass of collections.defaultdict, if its default_factory is set
2817 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002818
Christian Heimesf75dbef2008-02-08 00:11:31 +00002819- Fixed a minor memory leak in dictobject.c. The content of the free
2820 list was not freed on interpreter shutdown.
2821
Georg Brandl5a7eca12010-03-21 19:29:04 +00002822- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00002823 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002824
Georg Brandl3ee81df2008-05-17 18:14:43 +00002825- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2826 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002827 to compact the internal free lists of pre-allocted ints and floats.
2828
Georg Brandl3ee81df2008-05-17 18:14:43 +00002829- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2830 calls. Python expected the return type int but the fork familie
2831 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002832
Georg Brandl3ee81df2008-05-17 18:14:43 +00002833- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2834 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002835

2843 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002844
Georg Brandl3ee81df2008-05-17 18:14:43 +00002845- Patch #1473257: generator objects gain a gi_code attribute. This is
2846 the same object as the func_code attribute of the function that
2847 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002848
Georg Brandl3ee81df2008-05-17 18:14:43 +00002849- Issue #1920: "while 0" statements were completely removed by the
2850 compiler, even in the presence of an "else" clause, which is
2851 supposed to be run when the condition is false. Now the compiler
2852 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002853
Guido van Rossumeead05f2008-01-24 18:21:02 +00002854- A few crashers fixed: weakref_in_del.py (issue #1377858);
2855 loosing_dict_ref.py (issue #1303614, test67.py);
2856 borrowed_ref_[34].py (not in tracker).
2857
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002858- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002859 suppressed while an extension is loaded by calling SetErrorMode in
2860 dynload_win.c. The error is still reported properly.
2861
Georg Brandl3ee81df2008-05-17 18:14:43 +00002862- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002863 several extension methods and modules do not work without unicode
2864 support.
2865
Georg Brandl26543b12008-01-21 18:36:51 +00002866- Issue #1882: when compiling code from a string, encoding cookies in the
2867 second line of code were not always recognized correctly.
2868
Georg Brandl14404b62008-01-19 19:27:05 +00002869- Issue #1679: "0x" was taken as a valid integer literal.
2870
Georg Brandl6caad7d2008-01-26 14:19:22 +00002871- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002872 added.
2873
Christian Heimesc94e2b52008-01-14 04:13:37 +00002874- sys.float_info / PyFloat_GetInfo: The floating point information
2875 object was converted from a dict to a specialized structseq object.
2876
Georg Brandl3ee81df2008-05-17 18:14:43 +00002877- Patch #1816: Added sys.flags structseq. It exposes the status of
2878 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002879
Georg Brandl3ee81df2008-05-17 18:14:43 +00002880- Objects/structseq.c: Implemented new structseq representation. The
2881 patch makes structseqs (e.g. the return value of os.stat) more
2882 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002883
Georg Brandl3ee81df2008-05-17 18:14:43 +00002884- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00002906 and INF. float("nan"), float("inf") and float("-inf") now work on
2907 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002908
Georg Brandl3ee81df2008-05-17 18:14:43 +00002909- Compiler now generates simpler and faster code for dictionary
2910 literals. The oparg for BUILD_MAP now indicates an estimated
2911 dictionary size. There is a new opcode, STORE_MAP, for adding
2912 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002941- Patch #1739468: Directories and zipfiles containing a __main__.py
2942 file can now be directly executed by passing their name to the
2943 interpreter. The directory/zipfile is automatically inserted as the
2944 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002946- Issue #1265: Fix a problem with sys.settrace, if the tracing
2947 function uses a generator expression when at the same time the
2948 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002949
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002950- sets and frozensets now have an isdisjoint() method.
2951

2953
Neal Norwitz44f326e2007-10-05 05:29:17 +00002954- Fix warnings found by the new version of the Coverity checker.
2955
Georg Brandl5a7eca12010-03-21 19:29:04 +00002956- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00002957 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2958 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002959
Georg Brandl3ee81df2008-05-17 18:14:43 +00002960- Issue #1686386: Tuple's tp_repr did not take into account the
2961 possibility of having a self-referential tuple, which is possible
2962 from C code. Nor did object's tp_str consider that a type's tp_str
2963 could do something that could lead to an inifinite recursion.
2964 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2965 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002966
Georg Brandl3ee81df2008-05-17 18:14:43 +00002967- Issue #1164: It was possible to trigger deadlock when using the
2968 'print' statement to write to a file since the GIL was not released
2969 as needed. Now PyObject_Print() does the right thing along with
2970 various tp_print implementations of the built-in types and those in
2971 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002972
Georg Brandl3ee81df2008-05-17 18:14:43 +00002973- Issue #1147: Exceptions were directly allowing string exceptions in
2974 their throw() method even though string exceptions no longer
2975 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002976
Georg Brandl3ee81df2008-05-17 18:14:43 +00002977- Issue #1096: Prevent a segfault from getting the repr of a very
2978 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002979
Brett Cannon1e534b52007-09-07 04:18:30 +00002980- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002981 PyObject_Call() never calling back out to Python code to trigger
2982 recursion depth updates/checks. Required the creation of a static
2983 RuntimeError instance in case normalizing an exception put the
2984 recursion check value past its limit. Fixes crashers
2985 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002986
Georg Brandl3ee81df2008-05-17 18:14:43 +00002987- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003000- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003001 __*__ attributes. (Some already existed, e.g., __doc__ and
3002 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003003
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003004- Add -3 option to the interpreter to warn about features that are
3005 deprecated and will be changed/removed in Python 3.0.
3006
Georg Brandl2134e752007-05-21 20:34:16 +00003007- Patch #1686487: you can now pass any mapping after '**' in function
3008 calls.
3009
Collin Winter62903052007-05-18 23:11:24 +00003010- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003011 "except E as target:". This is to provide forwards compatibility
3012 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003013
Brett Cannon229cee22007-05-05 01:34:02 +00003014- Deprecate BaseException.message as per PEP 352.
3015
Georg Brandl3ee81df2008-05-17 18:14:43 +00003016- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003017 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003018
Vinay Sajip8549ce32007-05-06 17:53:37 +00003019- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003020 setting a plain string, ie don't expand to single letter identifiers.
3021
Raymond Hettinger13936692007-04-11 18:40:58 +00003022- Request #1191699: Slices can now be pickled.
3023
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003024- Request #1193128: str.translate() now allows a None argument for
3025 translations that only remove characters without re-mapping the
3026 remaining characters.
3027
Georg Brandl5cb76c12007-03-21 09:00:39 +00003028- Patch #1682205: a TypeError while unpacking an iterable is no longer
3029 masked by a generic one with the message "unpack non-sequence".
3030
Neal Norwitzaa754b72007-03-21 06:39:48 +00003031- Remove unused file Python/fmod.c.
3032
Guido van Rossum143b5642007-03-23 04:58:42 +00003033- Bug #1683368: The object.__init__() and object.__new__() methods are
3034 now stricter in rejecting excess arguments. The only time when
3035 either allows excess arguments is when it is not overridden and the
3036 other one is. For backwards compatibility, when both are
3037 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003038 warning later). Also, type.__init__() insists on the same signature
3039 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003040
Georg Brandl3ee81df2008-05-17 18:14:43 +00003041- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3042 object to complex using its __complex__() method before falling back
3043 to the __float__() method. Therefore, the functions in the cmath
3044 module now can operate on objects that define a __complex__()
3045 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003046
Georg Brandl3ee81df2008-05-17 18:14:43 +00003047- Patch #1623563: allow __class__ assignment for classes with
3048 __slots__. The old and the new class are still required to have the
3049 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003050

3055 ``object.__reduce_ex__()`` is called with an object that is faking
3056 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003057
Georg Brandl3ee81df2008-05-17 18:14:43 +00003058- Patch #1680015: Don't modify __slots__ tuple if it contains an

3062
Georg Brandl7b9c5552007-03-12 14:30:05 +00003063- Bug #1678647: write a newline after printing an exception in any
3064 case, even when converting the value to a string failed.
3065
Georg Brandl871f1bc2007-03-12 13:17:36 +00003066- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003067 its argument, if it exists. If not, it will work like before. This
3068 allows customizing the output of dir() in the presence of a
3069 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003070
Collin Winter276887b2007-03-12 16:11:39 +00003071- Patch #922167: Python no longer segfaults when faced with infinitely

Georg Brandl3ee81df2008-05-17 18:14:43 +00003077- Patch #1491866: change the complex() constructor to allow
3078 parthensized forms. This means complex(repr(x)) now works instead of
3079 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003080
Georg Brandlaa2321b2007-03-07 00:40:28 +00003081- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003082 makes the filenames the warning module prints much more sensible
3083 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003084

3086 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003087 variable is given, but break into the interactive interpreter just
3088 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00003095
Georg Brandl0fca97a2007-03-05 22:28:08 +00003096- Patch #1674228: when assigning a slice (old-style), check for the
3097 sq_ass_slice instead of the sq_slice slot.
3098
Georg Brandl3ee81df2008-05-17 18:14:43 +00003099- When printing an unraisable error, don't print exceptions. before
3100 the name. This duplicates the behavior whening normally printing
3101 exceptions.

3729 -- the failure just occurred later, with a more cumbersome
3730 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004011- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4012 with RFC 3207 and forgets any knowledge obtained from the server not
4013 obtained from the TLS negotiation itself. Patch contributed by Bill
4014 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004015
Georg Brandl3ee81df2008-05-17 18:14:43 +00004016- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004017 that the SMTP.starttls() caller no longer needs to call ehlo()
4018 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004019 does not claim to support starttls. Adds the
4020 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00004075- itertools.chain() now has an alternate constructor,

4101 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4102 silently miscode subclasses of those types. Now, it raises a
4103 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004104

Georg Brandl3ee81df2008-05-17 18:14:43 +00004119 time so that opening a database previously created with the DB_DUP
4120 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4121 opens. Specifically: dictionary assignment to a DB object will
4122 replace all values for a given key when the database allows
4123 duplicate values. DB users should use DB.put(k, v) when they want
4124 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004125

4131 characters with ASCII value less than 32. Also, it correctly quotes
4132 dots only if they occur on a single line, as opposed to the previous
4133 behavior of quoting dots if they are the second character of any
4134 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004135

4457-----
4458
Georg Brandl3ee81df2008-05-17 18:14:43 +00004459- Unified naming convention for free lists and their limits. All free
4460 lists in Object/ are named ``free_list``, the counter ``numfree``

4462 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004463
Georg Brandl3ee81df2008-05-17 18:14:43 +00004464- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4465 to ``PyTuple_SetItem``, it can be used to populate a brand new

4478
Georg Brandl3ee81df2008-05-17 18:14:43 +00004479- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4480 of w# format code incorrectly truncated the length to an int, even
4481 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4482 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004483
Georg Brandl3ee81df2008-05-17 18:14:43 +00004484- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4502- Fix some leftovers from the conversion from int to Py_ssize_t
4503 (relevant to strings and sequences of more than 2**31 items).
4504
4505- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4506 outside of pystate.c and should not be necessary.
4507
Georg Brandl3ee81df2008-05-17 18:14:43 +00004508- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4509 absolute imports. In earlier versions they might have used relative
4510 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004511
Georg Brandl3ee81df2008-05-17 18:14:43 +00004512- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4513 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004514
Georg Brandl3ee81df2008-05-17 18:14:43 +00004515- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

4525 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004526

Georg Brandl3ee81df2008-05-17 18:14:43 +00004540- Removed the macfs module. It had been deprecated since Python 2.5.
4541 This lead to the deprecation of macostools.touched() as it relied
4542 solely on macfs and was a no-op under OS X.
