950 an existing .py counterpart, override the co_filename attributes of all
951 code objects if the original filename is obsolete (which can happen if the

Georg Brandld2094602008-12-05 08:51:30 +0000991 method on file objects with closefd=False. The file descriptor is still

1203
1204- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
1205 302 conformant loader) will now work correctly in most cases (they

1366What's New in Python 2.6.1
1367==========================
1368
1369*Release date: 04-Dec-2008*
1370
1371Core and Builtins
1372-----------------
1373
1374- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1375 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1376 instead of throwing a MemoryError.
1377
1378- Issue #4367: Python would segfault during compiling when the unicodedata
1379 module couldn't be imported and \N escapes were present.
1380
1381- Issue #4348: Some bytearray methods returned that didn't cause any change to
1382 the bytearray, returned the same bytearray instead of a copy.
1383
1384- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1385
1386- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1387
1388- Issue #4048: The parser module now correctly validates relative imports.
1389
1390- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

1396- Issue #4209: Enabling unicode_literals and the print_function in the same
1397 __future__ import didn't work.
1398
1399- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1400 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1401 really executed because I cannot move to such directory on win2k)
1402
1403- Issue #4069: When set.remove(element) is used with a set element, the element
1404 is temporarily replaced with an equivalent frozenset. But the eventual
1405 KeyError would always report the empty frozenset([]) as the missing key. Now
1406 it correctly refers to the initial element.
1407

1409 again.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001558- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1559 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1560 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1561 ``printf`` function, whereas PyString_FromFormat has an independent

Vinay Sajip35e3b032008-09-01 14:33:59 +00001583- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001584 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1585 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1586 when given a tuple of classes as second argument, were looking up
1587 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1588 type object.
1589
Neal Norwitz18aa3882008-08-24 05:04:52 +00001590- Fix crashes on memory allocation failure found with failmalloc.

1659 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1660 for catch_warnings() also led to an improvement in the raising of a
1661 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001683- Issue #2975: When compiling several extension modules with Visual Studio 2008
1684 from the same python interpreter, some environment variables would grow
1685 without limit.
1686
Benjamin Peterson37346b22008-08-23 20:27:43 +00001687- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001724What's New in Python 2.6 beta 3?
1725================================
1726
Barry Warsaw07a4a382008-08-21 01:15:08 +00001727*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001728
1729Core and Builtins
1730-----------------
1731
Guido van Rossumf8402962008-08-20 15:01:50 +00001732- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1733 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1734 extensions do not automatically benefit from the class attribute
1735 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1736 to their tp_flags field if they care. This is a backwards
1737 compatibility feature; in 3.0, all types will use the cache by
1738 default.
1739
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001740- Keyword arguments can now follow starred arguments. (``f(a, *args,
1741 keyword=23)`` is now valid syntax.)
1742
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001743- ctypes function pointers that are COM methods have a boolean True
1744 value again.
1745
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001746- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1747 by denying s# to parse objects that have a releasebuffer procedure,
1748 and introducing s*.
1749
Georg Brandl1e13ea92008-08-11 09:07:59 +00001750- Issue #3537: Fix an assertion failure when an empty but presized dict
1751 object was stored in the freelist.
1752
Mark Dickinsonb6467572008-08-04 21:30:09 +00001753- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1754 ValueError consistently across platforms.
1755
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001756- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1757 (64bit Unix, for example), unichr() would truncate its argument and return
1758 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1759
Neal Norwitze7d8be82008-07-31 17:17:14 +00001760- Apply security patches from Apple.
1761
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001762- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1763 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1764
Antoine Pitrou92f82162008-07-25 22:22:08 +00001765- Issue #1819: function calls with several named parameters are now on
1766 average 35% faster (as measured by pybench).
1767
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001768- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1769 the python debugger steps into a class statement: the free variables (local
1770 variables defined in an outer scope) would be deleted from the outer scope.
1771
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001772- Issue #2620: Overflow checking when allocating or reallocating memory
1773 was not always being done properly in some python types and extension
1774 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1775 all been updated to perform better checks and places in the code that
1776 would previously leak memory on the error path when such an allocation
1777 failed have been fixed.

1780-------
1781
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001782- Issue #3612: Added some missing basic types in ctypes.wintypes.
1783
Benjamin Petersone977ad42008-08-20 01:42:01 +00001784- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1785 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1786
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001787- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1788 version reported by these tools does not necessarily follow the python
1789 version numbering scheme, so the module is less strict when parsing it.
1790
Nick Coghlanf70385a2008-08-18 12:42:46 +00001791- Issue #2235: Added Py3k warnings for types which will become unhashable
1792 under the stricter __hash__ inheritance rules in 3.0. Several types
1793 which did not meet the rules for hash invariants and were already
1794 unhashable in 3.0 have now been explicitly flagged as unhashable in
1795 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1796 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1797
Brett Cannon88f801d2008-08-18 00:46:22 +00001798- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1799 imported into the module but exposed as part of the module's API.
1800
Brett Cannon7b96f072008-08-18 00:41:11 +00001801- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1802
Brett Cannon46225e72008-08-18 00:36:52 +00001803- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1804
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001805- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1806
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001807- Issue #3575: Incremental decoder's decode function now takes bytearray
1808 by using 's*' instead of 't#'.
1809
Jesus Cea585ad8a2009-07-02 15:37:21 +00001810- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001811 fails unicode conversion on 2nd parameter. (windows only)
1812
Facundo Batista94f243a2008-08-17 03:38:39 +00001813- Issue 2464. urllib2 now supports a malformation in the URL received
1814 in a redirect.
1815
Brett Cannonabe423e2008-08-16 21:47:07 +00001816- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001817 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001818
Facundo Batistaeb90b782008-08-16 14:44:07 +00001819- Issue #2776: fixed small issue when handling an URL with double slash
1820 after a 302 response in the case of not going through a proxy.
1821
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001822- Issue #2676: in the email package, content-type parsing was hanging on
1823 pathological input because of quadratic or exponential behaviour of a
1824 regular expression.
1825
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001826- Issue #3476: binary buffered reading through the new "io" library is now
1827 thread-safe.
1828
Brett Cannonbf3157b2008-08-14 05:00:03 +00001829- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1830 since mimetools itself is deprecated. Because modules are cached, all
1831 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1832
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001833- Issue #3134: shutil referenced undefined WindowsError symbol.
1834
Robert Schuppenies14646332008-08-10 11:01:53 +00001835- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1836 menu entries were not deleted.
1837
Brett Cannon83e81842008-08-09 23:30:55 +00001838- Copied the implementation of reduce() to _functools.reduce() to have a
1839 version that did not raise a DeprecationWarning under -3.
1840
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001841- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1842 a MemoryError rather than silently stop the iteration.
1843
Guido van Rossum59ce9012008-08-09 14:55:34 +00001844- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1845 to _sre.compile() will now be rejected. This should not affect anybody
1846 since the re.compile() function never generates invalid re-bytecode.
1847
Skip Montanaroa032bf42008-08-08 22:52:51 +00001848- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1849 upon first access it can be automatically initialized from the csv file if
1850 it wasn't initialized during instantiation.
1851
Brett Cannon3aa2a492008-08-06 22:28:09 +00001852- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1853 the reload() built-in has been removed.
1854
Brett Cannon7e30b672008-08-04 21:52:25 +00001855- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001856 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00001857 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
1858 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
1859 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
1860 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1861 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00001862
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001863- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1864 raised an AttributeError.
1865
Benjamin Peterson01a24322008-07-28 23:35:27 +00001866- Issue #2523: Fix quadratic behaviour when read()ing a binary file without

1924-----------------
1925
Georg Brandl3e483f62008-07-16 22:57:41 +00001926- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1927 its methods now allow for items objects that can be converted to
1928 an integer using operator.index().
1929
Mark Dickinson64b7e502008-07-16 09:40:03 +00001930- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1931 produced a ValueError instead of giving the correct float.
1932
Eric Smitha5fa5a22008-07-16 00:11:49 +00001933- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1934 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1935
Mark Dickinson7103aa42008-07-15 19:08:33 +00001936- Issue #3008: the float type has a new instance method 'float.hex'
1937 and a new class method 'float.fromhex' to convert floating-point
1938 numbers to and from hexadecimal strings, respectively.
1939
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001940- Issue #2235: __hash__ is once again inherited by default. To allow
1941 collections.Hashable to remain meaningful in the presence of the
1942 default hash implementation (object.__hash__), it is now possible
1943 to explicit block inheritance of hash by setting __hash__=None at
1944 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1945 level.
1946
Nick Coghlanb028f502008-07-13 14:52:36 +00001947- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1948 the parent module cannot be found while performing an absolute import.
1949 This means that an incorrectly defined __package__ attribute will
1950 now only prevent relative imports in that module rather than causing
1951 all imports from that module to fail.
1952
Nick Coghlan14ff9942008-07-08 14:21:42 +00001953- Issue #2517: Allow unicode messages in Exceptions again by correctly

1963 another thread's dictionary.
1964
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001965- Issue #3004: Minor change to slice.indices(): the start and stop
1966 arguments are now treated identically, making the behaviour easier
1967 to describe and understand. For example, slice(None, -10,
1968 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1969 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1970 10, -1).
1971
Georg Brandl278fc502008-07-19 12:46:12 +00001972- Issue #3219: Calling a function with repeated keyword arguments,
1973 f(a=2, a=23), would not cause a syntax error. This was a regression
1974 from 2.4 caused by the switch to the new compiler.

1977 other freelists. Changes their CompactFreeList apis into

1984 api functions without holding the GIL, which could lead to a fatal
1985 error when they failed.
1986
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001987- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002012- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2013 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002014 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002015 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002031- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl3ee81df2008-05-17 18:14:43 +00002486- Issue #1631171: Re-implement the 'warnings' module in C (the
2487 original Python code has been kept as backup). This will allow for
2488 using the 'warning's machinery in such places as the parser where
2489 use of pure Python code is not possible. Both the ``showarning()``
2490 and ``formatwarning()`` gain an optional 'line' argument which is
2491 not called by default for backwards-compatibility reasons. Setting
2492 ``warnings.showwarning()`` to an implementation that lacks support
2493 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002535- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002536 extension modules between 32 and 64 bit platforms. See the distutls

2549 so the controlled environment will more closely mirror the typical
2550 script environment. This supports setup.py scripts that refer to
2551 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002556- Issue #2550: The approach used by client/server code for obtaining
2557 ports to listen on in network-oriented tests has been refined in an
2558 effort to facilitate running multiple instances of the entire
2559 regression test suite in parallel without issue.
2560 test_support.bind_port() has been fixed such that it will always
2561 return a unique port -- which wasn't always the case with the
2562 previous implementation, especially if socket options had been set
2563 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2564 new implementation of bind_port() will actually raise an exception
2565 if it is passed an AF_INET/SOCK_STREAM socket with either the
2566 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2567 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2568 the socket it's been passed. This currently only applies to
2569 Windows. This option prevents any other sockets from binding to the
2570 host/port we've bound to, thus removing the possibility of the
2571 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2572 when a second SOCK_STREAM socket binds and accepts to a host/port
2573 that's already been bound by another socket. The optional preferred
2574 port parameter to bind_port() has been removed. Under no
2575 circumstances should tests be hard coding ports!
2576
2577 test_support.find_unused_port() has also been introduced, which will
2578 pass a temporary socket object to bind_port() in order to obtain an
2579 unused port. The temporary socket object is then closed and
2580 deleted, and the port is returned. This method should only be used
2581 for obtaining an unused port in order to pass to an external program
2582 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2583 a parameter to a server-oriented class that doesn't give you direct
2584 access to the underlying socket used.
2585
2586 Finally, test_support.HOST has been introduced, which should be used
2587 for the host argument of any relevant socket calls (i.e. bind and
2588 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002589
2590 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002591 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002592 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2593 test_asynchat and test_socket_ssl.
2594
Georg Brandl3ee81df2008-05-17 18:14:43 +00002595 It is now possible for multiple instances of the regression test
2596 suite to run in parallel without issue.

2863-----------------
2864
Fred Drakea8ee94b2008-03-01 02:45:07 +00002865- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002866 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002867
Georg Brandlad61bc82008-02-23 15:11:18 +00002868- Issue #2067: file.__exit__() now calls subclasses' close() method.
2869
2870- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002871
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002872- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002873 issue 215555 for a discussion.
2874
Eric Smitha73fbe72008-02-23 03:09:44 +00002875- Added the future_builtins module, which contains hex() and oct().
2876 These are the PEP 3127 version of these functions, designed to be
2877 compatible with the hex() and oct() builtins from Python 3.0. They
2878 differ slightly in their output formats from the existing, unchanged
2879 Python 2.6 builtins. The expected usage of the future_builtins
2880 module is:
2881 from future_builtins import hex, oct
2882
Eric Smith7ef40bf2008-02-20 23:34:22 +00002883- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2884 exponents for exponents with absolute value < 100. Follows C99
2885 standard. This is a change on Windows, which would use 3 digits.
2886 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2887 so that any alterations it does to the resulting string will be
2888 available in stringlib/formatter.h (for float.__format__).
2889
Eric Smith5a3c1352008-02-19 13:21:56 +00002890- Implemented PEP 3101, Advanced String Formatting. This adds a new
2891 builtin format(); a format() method for str and unicode; a
2892 __format__() method to object, str, unicode, int, long, float, and
2893 datetime; the class string.Formatter; and the C API
2894 PyObject_Format().
2895
Georg Brandl3ee81df2008-05-17 18:14:43 +00002896- Fixed several potential crashes, all caused by specially crafted
2897 __del__ methods exploiting objects in temporarily inconsistent
2898 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002899
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002900- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002901 prevent a possible crash: an Abstract Base Class would try to access
2902 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002907- Clear all free lists during a gc.collect() of the highest generation
2908 in order to allow pymalloc to free more arenas. Python may give back
2909 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002910
Georg Brandl3ee81df2008-05-17 18:14:43 +00002911- Issue #2045: Fix an infinite recursion triggered when printing a
2912 subclass of collections.defaultdict, if its default_factory is set
2913 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002914
Christian Heimesf75dbef2008-02-08 00:11:31 +00002915- Fixed a minor memory leak in dictobject.c. The content of the free
2916 list was not freed on interpreter shutdown.
2917
Georg Brandl5a7eca12010-03-21 19:29:04 +00002918- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00002919 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002920
Georg Brandl3ee81df2008-05-17 18:14:43 +00002921- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2922 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002923 to compact the internal free lists of pre-allocted ints and floats.
2924
Georg Brandl3ee81df2008-05-17 18:14:43 +00002925- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2926 calls. Python expected the return type int but the fork familie
2927 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002928

Georg Brandl3ee81df2008-05-17 18:14:43 +00002941- Patch #1473257: generator objects gain a gi_code attribute. This is
2942 the same object as the func_code attribute of the function that
2943 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002944
Georg Brandl3ee81df2008-05-17 18:14:43 +00002945- Issue #1920: "while 0" statements were completely removed by the
2946 compiler, even in the presence of an "else" clause, which is
2947 supposed to be run when the condition is false. Now the compiler
2948 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002949
Guido van Rossumeead05f2008-01-24 18:21:02 +00002950- A few crashers fixed: weakref_in_del.py (issue #1377858);

Christian Heimesb2302ba2008-01-23 17:15:06 +00002955 suppressed while an extension is loaded by calling SetErrorMode in
2956 dynload_win.c. The error is still reported properly.
2957
Georg Brandl3ee81df2008-05-17 18:14:43 +00002958- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002959 several extension methods and modules do not work without unicode
2960 support.
2961
Georg Brandl26543b12008-01-21 18:36:51 +00002962- Issue #1882: when compiling code from a string, encoding cookies in the
2963 second line of code were not always recognized correctly.
2964
Georg Brandl14404b62008-01-19 19:27:05 +00002965- Issue #1679: "0x" was taken as a valid integer literal.
2966
Georg Brandl6caad7d2008-01-26 14:19:22 +00002967- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002968 added.
2969
Christian Heimesc94e2b52008-01-14 04:13:37 +00002970- sys.float_info / PyFloat_GetInfo: The floating point information
2971 object was converted from a dict to a specialized structseq object.
2972
Georg Brandl3ee81df2008-05-17 18:14:43 +00002973- Patch #1816: Added sys.flags structseq. It exposes the status of
2974 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002975
Georg Brandl3ee81df2008-05-17 18:14:43 +00002976- Objects/structseq.c: Implemented new structseq representation. The
2977 patch makes structseqs (e.g. the return value of os.stat) more
2978 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002979
Georg Brandl3ee81df2008-05-17 18:14:43 +00002980- Patch #1700288: added a type attribute cache that caches method
2981 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002982
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002983- Bug #1776: __import__() no longer accepts filenames on any platform.
2984 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002985
Georg Brandlaed6c662008-01-07 17:25:53 +00002986- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2987
Georg Brandl3ee81df2008-05-17 18:14:43 +00002988- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2989 envvar and sys.dont_write_bytecode attribute. All these can be set
2990 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002991
Georg Brandl3ee81df2008-05-17 18:14:43 +00002992- Improve some exception messages when Windows fails to load an
2993 extension module. Now we get for example '%1 is not a valid Win32
2994 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002995
Georg Brandl3ee81df2008-05-17 18:14:43 +00002996- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002998- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2999 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003000
Christian Heimes0a8143f2007-12-18 23:22:54 +00003001- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003002 and INF. float("nan"), float("inf") and float("-inf") now work on
3003 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003004
Georg Brandl3ee81df2008-05-17 18:14:43 +00003005- Compiler now generates simpler and faster code for dictionary
3006 literals. The oparg for BUILD_MAP now indicates an estimated
3007 dictionary size. There is a new opcode, STORE_MAP, for adding
3008 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003012- Issue #1620: New property decorator syntax was modifying the
3013 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00003014
Georg Brandl3ee81df2008-05-17 18:14:43 +00003015- Issue #1538: Avoid copying string in split/rsplit if the split char
3016 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00003017
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003018- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003019 SystemError.
3020
Nick Coghlanef01d822007-12-03 12:55:17 +00003021- PEP 366: Allow explicit relative imports when executing modules

3026 running, and if the deallocation of its frames somehow calls the
3027 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003028

3033
Georg Brandl3ee81df2008-05-17 18:14:43 +00003034- Issue #1460: The utf-7 incremental decoder did not accept truncated
3035 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00003036
Georg Brandl3ee81df2008-05-17 18:14:43 +00003037- Patch #1739468: Directories and zipfiles containing a __main__.py
3038 file can now be directly executed by passing their name to the
3039 interpreter. The directory/zipfile is automatically inserted as the
3040 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003041
Georg Brandl3ee81df2008-05-17 18:14:43 +00003042- Issue #1265: Fix a problem with sys.settrace, if the tracing
3043 function uses a generator expression when at the same time the
3044 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003045
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003046- sets and frozensets now have an isdisjoint() method.
3047
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003048- optimize the performance of builtin.sum().
3049
Neal Norwitz44f326e2007-10-05 05:29:17 +00003050- Fix warnings found by the new version of the Coverity checker.
3051
Georg Brandl5a7eca12010-03-21 19:29:04 +00003052- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003053 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3054 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003055
Georg Brandl3ee81df2008-05-17 18:14:43 +00003056- Issue #1686386: Tuple's tp_repr did not take into account the
3057 possibility of having a self-referential tuple, which is possible
3058 from C code. Nor did object's tp_str consider that a type's tp_str
3059 could do something that could lead to an inifinite recursion.
3060 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3061 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003062
Georg Brandl3ee81df2008-05-17 18:14:43 +00003063- Issue #1164: It was possible to trigger deadlock when using the
3064 'print' statement to write to a file since the GIL was not released
3065 as needed. Now PyObject_Print() does the right thing along with
3066 various tp_print implementations of the built-in types and those in
3067 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003068
Georg Brandl3ee81df2008-05-17 18:14:43 +00003069- Issue #1147: Exceptions were directly allowing string exceptions in
3070 their throw() method even though string exceptions no longer
3071 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003072
Georg Brandl3ee81df2008-05-17 18:14:43 +00003073- Issue #1096: Prevent a segfault from getting the repr of a very
3074 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003075
Brett Cannon1e534b52007-09-07 04:18:30 +00003076- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003077 PyObject_Call() never calling back out to Python code to trigger
3078 recursion depth updates/checks. Required the creation of a static
3079 RuntimeError instance in case normalizing an exception put the
3080 recursion check value past its limit. Fixes crashers
3081 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003082
Georg Brandl3ee81df2008-05-17 18:14:43 +00003083- Patch #1031213: Decode source line in SyntaxErrors back to its

3087 with %G.
3088
Georg Brandl3ee81df2008-05-17 18:14:43 +00003089- Prevent expandtabs() on string and unicode objects from causing a
3090 segfault when a large width is passed on 32-bit platforms.

Neal Norwitz0ac60192007-05-27 04:08:54 +00003096- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003097 __*__ attributes. (Some already existed, e.g., __doc__ and
3098 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003099
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003100- Add -3 option to the interpreter to warn about features that are
3101 deprecated and will be changed/removed in Python 3.0.
3102
Georg Brandl2134e752007-05-21 20:34:16 +00003103- Patch #1686487: you can now pass any mapping after '**' in function
3104 calls.
3105
Collin Winter62903052007-05-18 23:11:24 +00003106- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003107 "except E as target:". This is to provide forwards compatibility
3108 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003109
Brett Cannon229cee22007-05-05 01:34:02 +00003110- Deprecate BaseException.message as per PEP 352.
3111
Georg Brandl3ee81df2008-05-17 18:14:43 +00003112- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003113 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003114
Vinay Sajip8549ce32007-05-06 17:53:37 +00003115- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003116 setting a plain string, ie don't expand to single letter identifiers.
3117
Raymond Hettinger13936692007-04-11 18:40:58 +00003118- Request #1191699: Slices can now be pickled.
3119
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003120- Request #1193128: str.translate() now allows a None argument for
3121 translations that only remove characters without re-mapping the
3122 remaining characters.
3123
Georg Brandl5cb76c12007-03-21 09:00:39 +00003124- Patch #1682205: a TypeError while unpacking an iterable is no longer
3125 masked by a generic one with the message "unpack non-sequence".
3126
Neal Norwitzaa754b72007-03-21 06:39:48 +00003127- Remove unused file Python/fmod.c.
3128
Guido van Rossum143b5642007-03-23 04:58:42 +00003129- Bug #1683368: The object.__init__() and object.__new__() methods are
3130 now stricter in rejecting excess arguments. The only time when
3131 either allows excess arguments is when it is not overridden and the
3132 other one is. For backwards compatibility, when both are
3133 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003134 warning later). Also, type.__init__() insists on the same signature
3135 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003136
Georg Brandl3ee81df2008-05-17 18:14:43 +00003137- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3138 object to complex using its __complex__() method before falling back
3139 to the __float__() method. Therefore, the functions in the cmath
3140 module now can operate on objects that define a __complex__()
3141 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003142
Georg Brandl3ee81df2008-05-17 18:14:43 +00003143- Patch #1623563: allow __class__ assignment for classes with
3144 __slots__. The old and the new class are still required to have the
3145 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003146
Georg Brandl3ee81df2008-05-17 18:14:43 +00003147- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00003150- Patch #1462488: Python no longer segfaults when
3151 ``object.__reduce_ex__()`` is called with an object that is faking
3152 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003153
Georg Brandl3ee81df2008-05-17 18:14:43 +00003154- Patch #1680015: Don't modify __slots__ tuple if it contains an

3158
Georg Brandl7b9c5552007-03-12 14:30:05 +00003159- Bug #1678647: write a newline after printing an exception in any
3160 case, even when converting the value to a string failed.
3161
Georg Brandl871f1bc2007-03-12 13:17:36 +00003162- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003163 its argument, if it exists. If not, it will work like before. This
3164 allows customizing the output of dir() in the presence of a
3165 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003166
Collin Winter276887b2007-03-12 16:11:39 +00003167- Patch #922167: Python no longer segfaults when faced with infinitely
3168 self-recursive reload() calls (as reported by bug #742342).
3169
Georg Brandl3ee81df2008-05-17 18:14:43 +00003170- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00003173- Patch #1491866: change the complex() constructor to allow
3174 parthensized forms. This means complex(repr(x)) now works instead of
3175 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003176
Georg Brandlaa2321b2007-03-07 00:40:28 +00003177- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003178 makes the filenames the warning module prints much more sensible
3179 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003180
Georg Brandl49aafc92007-03-07 00:34:46 +00003181- Variant of patch #697613: don't exit the interpreter on a SystemExit
3182 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003183 variable is given, but break into the interactive interpreter just
3184 like on other exceptions or normal program exit.

Georg Brandlfb4b3b72007-04-24 15:27:13 +00003684- Bug #1706381: Specifying the SWIG option "-c++" in the setup.py file
3685 (as opposed to the command line) will now write file names ending in
3686 ".cpp" too.
3687
Facundo Batistad918a652007-04-24 13:54:38 +00003688- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003689 the client's request was successfully received, understood, and
3690 accepted. Now in these cases no error is raised in urllib (issue
3691 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00003692

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00003699- Added a timeout parameter to the constructor of other protocols
3700 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3701 work started with create_connection() and timeout in httplib, and
3702 closes patch #723312.
3703
Vinay Sajip8549ce32007-05-06 17:53:37 +00003704- Patch #1676823: Added create_connection() to socket.py, which may be
3705 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00003706 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00003707
Martin v. Löwis0af33882007-03-23 13:27:15 +00003708- Bug #978833: Revert r50844, as it broke _socketobject.dup.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003715- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
3716 to True (which is not the default), it visits symlinks pointing to

3720 GNOME or KDE browser, depending on whether there is a session of one
3721 of those present. Also, it tries the Windows default browser before
3722 trying Mozilla variants.

3728
Georg Brandlf66b6032007-03-14 08:27:52 +00003729- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00003730 AttributeError instead of an IOError when the server's response
3731 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003732
Georg Brandl3ee81df2008-05-17 18:14:43 +00003733- Patch #957650: "%var%" environment variable references are now
3734 properly expanded in ntpath.expandvars(), also "~user" home
3735 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00003736
Georg Brandl3ee81df2008-05-17 18:14:43 +00003737- Patch #1429539: pdb now correctly initializes the __main__ module
3738 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003739 correctly now.
3740
Georg Brandlbad6f192007-03-13 21:32:56 +00003741- The nonobvious commands.getstatus() function is now deprecated.

3747
Georg Brandl3ee81df2008-05-17 18:14:43 +00003748- Patch #1530482: add pydoc.render_doc() which returns the
3749 documentation for a thing instead of paging it to stdout, which
3750 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00003751
Georg Brandl3ee81df2008-05-17 18:14:43 +00003752- Patch #1533909: the timeit module now accepts callables in addition

3758 parameter which can be set to False to prevent the default
3759 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00003760
Georg Brandl9e6b4702007-03-13 18:15:41 +00003761- Patch #1581073: add a flag to textwrap that prevents the dropping of
3762 whitespace while wrapping.
3763
Georg Brandl92a6bae2007-03-13 17:43:32 +00003764- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003765 are set for invalid interpolation sequences that would lead to
3766 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00003767

Collin Winter22c42ba2007-03-10 02:51:26 +00003801

3809 returned string up to the first NUL character.
3810

3820
Georg Brandl3ee81df2008-05-17 18:14:43 +00003821- unittest now verifies more of its assumptions. In particular,
3822 TestCase and TestSuite subclasses (not instances) are no longer
3823 accepted in TestSuite.addTest(). This should cause no
3824 incompatibility since it never made sense with ordinary subclasses
3825 -- the failure just occurred later, with a more cumbersome
3826 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00003827

3835 given a unicode argument and os.listdir() returns unicode filenames.
3836
Georg Brandl3ee81df2008-05-17 18:14:43 +00003837- Patch #1673619: setup.py identifies extension modules it doesn't
3838 know how to build and those it knows how to build but that fail to
3839 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004215 time so that opening a database previously created with the DB_DUP
4216 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4217 opens. Specifically: dictionary assignment to a DB object will
4218 replace all values for a given key when the database allows
4219 duplicate values. DB users should use DB.put(k, v) when they want
4220 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004221

4227 characters with ASCII value less than 32. Also, it correctly quotes
4228 dots only if they occur on a single line, as opposed to the previous
4229 behavior of quoting dots if they are the second character of any
4230 line.
