1360What's New in Python 2.6.1
1361==========================
1362
1363*Release date: 04-Dec-2008*
1364
1365Core and Builtins
1366-----------------
1367
1368- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1369 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1370 instead of throwing a MemoryError.
1371
1372- Issue #4367: Python would segfault during compiling when the unicodedata
1373 module couldn't be imported and \N escapes were present.
1374
1375- Issue #4348: Some bytearray methods returned that didn't cause any change to
1376 the bytearray, returned the same bytearray instead of a copy.
1377
1378- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1379
1380- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1381
1382- Issue #4048: The parser module now correctly validates relative imports.
1383
1384- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

1389
1390- Issue #4209: Enabling unicode_literals and the print_function in the same
1391 __future__ import didn't work.
1392
1393- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1394 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1395 really executed because I cannot move to such directory on win2k)
1396
1397- Issue #4069: When set.remove(element) is used with a set element, the element
1398 is temporarily replaced with an equivalent frozenset. But the eventual
1399 KeyError would always report the empty frozenset([]) as the missing key. Now
1400 it correctly refers to the initial element.
1401
1402- Fixed C99 style comments in several files. Python is now C89 compatible
1403 again.

1551
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001552- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1553 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1554 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1555 ``printf`` function, whereas PyString_FromFormat has an independent
1556 implementation and uses "%zd" on all platforms for size_t values.
1557 This makes a difference on win64, where ``printf`` needs "%Id" to display
1558 64bit values.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001718What's New in Python 2.6 beta 3?
1719================================
1720
Barry Warsaw07a4a382008-08-21 01:15:08 +00001721*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001722
1723Core and Builtins
1724-----------------
1725
Guido van Rossumf8402962008-08-20 15:01:50 +00001726- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1727 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1728 extensions do not automatically benefit from the class attribute
1729 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1730 to their tp_flags field if they care. This is a backwards
1731 compatibility feature; in 3.0, all types will use the cache by
1732 default.
1733
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001734- Keyword arguments can now follow starred arguments. (``f(a, *args,
1735 keyword=23)`` is now valid syntax.)
1736
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001737- ctypes function pointers that are COM methods have a boolean True
1738 value again.
1739
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001740- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1741 by denying s# to parse objects that have a releasebuffer procedure,
1742 and introducing s*.
1743
Georg Brandl1e13ea92008-08-11 09:07:59 +00001744- Issue #3537: Fix an assertion failure when an empty but presized dict
1745 object was stored in the freelist.
1746
Mark Dickinsonb6467572008-08-04 21:30:09 +00001747- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1748 ValueError consistently across platforms.
1749
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001750- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1751 (64bit Unix, for example), unichr() would truncate its argument and return
1752 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1753
Neal Norwitze7d8be82008-07-31 17:17:14 +00001754- Apply security patches from Apple.
1755
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001756- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1757 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1758
Antoine Pitrou92f82162008-07-25 22:22:08 +00001759- Issue #1819: function calls with several named parameters are now on
1760 average 35% faster (as measured by pybench).
1761
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001762- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1763 the python debugger steps into a class statement: the free variables (local
1764 variables defined in an outer scope) would be deleted from the outer scope.
1765
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001766- Issue #2620: Overflow checking when allocating or reallocating memory
1767 was not always being done properly in some python types and extension
1768 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1769 all been updated to perform better checks and places in the code that
1770 would previously leak memory on the error path when such an allocation
1771 failed have been fixed.

1775
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001776- Issue #3612: Added some missing basic types in ctypes.wintypes.
1777
Benjamin Petersone977ad42008-08-20 01:42:01 +00001778- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1779 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1780
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001781- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1782 version reported by these tools does not necessarily follow the python
1783 version numbering scheme, so the module is less strict when parsing it.
1784
Nick Coghlanf70385a2008-08-18 12:42:46 +00001785- Issue #2235: Added Py3k warnings for types which will become unhashable
1786 under the stricter __hash__ inheritance rules in 3.0. Several types
1787 which did not meet the rules for hash invariants and were already
1788 unhashable in 3.0 have now been explicitly flagged as unhashable in
1789 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1790 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1791
Brett Cannon88f801d2008-08-18 00:46:22 +00001792- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1793 imported into the module but exposed as part of the module's API.
1794
Brett Cannon7b96f072008-08-18 00:41:11 +00001795- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1796
Brett Cannon46225e72008-08-18 00:36:52 +00001797- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001799- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1800
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001801- Issue #3575: Incremental decoder's decode function now takes bytearray
1802 by using 's*' instead of 't#'.
1803
Jesus Cea585ad8a2009-07-02 15:37:21 +00001804- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001805 fails unicode conversion on 2nd parameter. (windows only)
1806
Facundo Batista94f243a2008-08-17 03:38:39 +00001807- Issue 2464. urllib2 now supports a malformation in the URL received
1808 in a redirect.
1809
Brett Cannonabe423e2008-08-16 21:47:07 +00001810- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001811 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001812
Facundo Batistaeb90b782008-08-16 14:44:07 +00001813- Issue #2776: fixed small issue when handling an URL with double slash
1814 after a 302 response in the case of not going through a proxy.
1815
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001816- Issue #2676: in the email package, content-type parsing was hanging on
1817 pathological input because of quadratic or exponential behaviour of a
1818 regular expression.
1819
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001820- Issue #3476: binary buffered reading through the new "io" library is now
1821 thread-safe.
1822
Brett Cannonbf3157b2008-08-14 05:00:03 +00001823- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1824 since mimetools itself is deprecated. Because modules are cached, all
1825 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1826
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001827- Issue #3134: shutil referenced undefined WindowsError symbol.
1828
Robert Schuppenies14646332008-08-10 11:01:53 +00001829- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1830 menu entries were not deleted.
1831
Brett Cannon83e81842008-08-09 23:30:55 +00001832- Copied the implementation of reduce() to _functools.reduce() to have a
1833 version that did not raise a DeprecationWarning under -3.
1834
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001835- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1836 a MemoryError rather than silently stop the iteration.
1837
Guido van Rossum59ce9012008-08-09 14:55:34 +00001838- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1839 to _sre.compile() will now be rejected. This should not affect anybody
1840 since the re.compile() function never generates invalid re-bytecode.
1841
Skip Montanaroa032bf42008-08-08 22:52:51 +00001842- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1843 upon first access it can be automatically initialized from the csv file if
1844 it wasn't initialized during instantiation.
1845
Brett Cannon3aa2a492008-08-06 22:28:09 +00001846- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1847 the reload() built-in has been removed.
1848
Brett Cannon7e30b672008-08-04 21:52:25 +00001849- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001850 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001861 asking for a specific length. This problem only affected files opened
1862 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001863
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001864- Issue #3449: Update decimal module to use most recent specification
1865 (v. 1.68) and tests (v. 2.58) from IBM.
1866

1913================================
1914
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001915*Release date: 17-Jul-2008*

1918-----------------
1919
Georg Brandl3e483f62008-07-16 22:57:41 +00001920- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1921 its methods now allow for items objects that can be converted to
1922 an integer using operator.index().
1923
Mark Dickinson64b7e502008-07-16 09:40:03 +00001924- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1925 produced a ValueError instead of giving the correct float.
1926
Eric Smitha5fa5a22008-07-16 00:11:49 +00001927- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1928 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1929
Mark Dickinson7103aa42008-07-15 19:08:33 +00001930- Issue #3008: the float type has a new instance method 'float.hex'
1931 and a new class method 'float.fromhex' to convert floating-point
1932 numbers to and from hexadecimal strings, respectively.
1933
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001934- Issue #2235: __hash__ is once again inherited by default. To allow
1935 collections.Hashable to remain meaningful in the presence of the
1936 default hash implementation (object.__hash__), it is now possible
1937 to explicit block inheritance of hash by setting __hash__=None at
1938 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1939 level.
1940
Nick Coghlanb028f502008-07-13 14:52:36 +00001941- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1942 the parent module cannot be found while performing an absolute import.
1943 This means that an incorrectly defined __package__ attribute will
1944 now only prevent relative imports in that module rather than causing
1945 all imports from that module to fail.
1946
Nick Coghlan14ff9942008-07-08 14:21:42 +00001947- Issue #2517: Allow unicode messages in Exceptions again by correctly

1952 set to a custom object whose write() method happens to install
1953 another file in sys.stdout.
1954
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001955- Issue #3088: Corrected a race condition in classes derived from
1956 threading.local: the first member set by a thread could be saved in
1957 another thread's dictionary.
1958
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001959- Issue #3004: Minor change to slice.indices(): the start and stop
1960 arguments are now treated identically, making the behaviour easier
1961 to describe and understand. For example, slice(None, -10,
1962 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1963 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1964 10, -1).
1965
Georg Brandl278fc502008-07-19 12:46:12 +00001966- Issue #3219: Calling a function with repeated keyword arguments,
1967 f(a=2, a=23), would not cause a syntax error. This was a regression
1968 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001969
Georg Brandl278fc502008-07-19 12:46:12 +00001970- Issue #2862: Make int and float freelist management consistent with
1971 other freelists. Changes their CompactFreeList apis into
1972 ClearFreeList apis and calls them via gc.collect().

1978 api functions without holding the GIL, which could lead to a fatal
1979 error when they failed.
1980
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001981- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002006- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2007 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002008 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002009 content-length. The problem had been corrected in the 2.4 branch, but never
2010 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002025- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2026 handling is now the same as that of other special attributes like __name__).

Georg Brandl3ee81df2008-05-17 18:14:43 +00002480- Issue #1631171: Re-implement the 'warnings' module in C (the
2481 original Python code has been kept as backup). This will allow for
2482 using the 'warning's machinery in such places as the parser where
2483 use of pure Python code is not possible. Both the ``showarning()``
2484 and ``formatwarning()`` gain an optional 'line' argument which is
2485 not called by default for backwards-compatibility reasons. Setting
2486 ``warnings.showwarning()`` to an implementation that lacks support
2487 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002550- Issue #2550: The approach used by client/server code for obtaining
2551 ports to listen on in network-oriented tests has been refined in an
2552 effort to facilitate running multiple instances of the entire
2553 regression test suite in parallel without issue.
2554 test_support.bind_port() has been fixed such that it will always
2555 return a unique port -- which wasn't always the case with the
2556 previous implementation, especially if socket options had been set
2557 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2558 new implementation of bind_port() will actually raise an exception
2559 if it is passed an AF_INET/SOCK_STREAM socket with either the
2560 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2561 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2562 the socket it's been passed. This currently only applies to
2563 Windows. This option prevents any other sockets from binding to the
2564 host/port we've bound to, thus removing the possibility of the
2565 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2566 when a second SOCK_STREAM socket binds and accepts to a host/port
2567 that's already been bound by another socket. The optional preferred
2568 port parameter to bind_port() has been removed. Under no
2569 circumstances should tests be hard coding ports!
2570
2571 test_support.find_unused_port() has also been introduced, which will
2572 pass a temporary socket object to bind_port() in order to obtain an
2573 unused port. The temporary socket object is then closed and
2574 deleted, and the port is returned. This method should only be used
2575 for obtaining an unused port in order to pass to an external program
2576 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2577 a parameter to a server-oriented class that doesn't give you direct
2578 access to the underlying socket used.
2579
2580 Finally, test_support.HOST has been introduced, which should be used
2581 for the host argument of any relevant socket calls (i.e. bind and
2582 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002583
2584 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002585 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002586 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2587 test_asynchat and test_socket_ssl.
2588
Georg Brandl3ee81df2008-05-17 18:14:43 +00002589 It is now possible for multiple instances of the regression test
2590 suite to run in parallel without issue.

2857-----------------
2858
Fred Drakea8ee94b2008-03-01 02:45:07 +00002859- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002860 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002865
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002866- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002867 issue 215555 for a discussion.
2868
Eric Smitha73fbe72008-02-23 03:09:44 +00002869- Added the future_builtins module, which contains hex() and oct().
2870 These are the PEP 3127 version of these functions, designed to be
2871 compatible with the hex() and oct() builtins from Python 3.0. They
2872 differ slightly in their output formats from the existing, unchanged
2873 Python 2.6 builtins. The expected usage of the future_builtins
2874 module is:
2875 from future_builtins import hex, oct
2876
Eric Smith7ef40bf2008-02-20 23:34:22 +00002877- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2878 exponents for exponents with absolute value < 100. Follows C99
2879 standard. This is a change on Windows, which would use 3 digits.
2880 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2881 so that any alterations it does to the resulting string will be
2882 available in stringlib/formatter.h (for float.__format__).
2883
Eric Smith5a3c1352008-02-19 13:21:56 +00002884- Implemented PEP 3101, Advanced String Formatting. This adds a new
2885 builtin format(); a format() method for str and unicode; a
2886 __format__() method to object, str, unicode, int, long, float, and
2887 datetime; the class string.Formatter; and the C API
2888 PyObject_Format().
2889
Georg Brandl3ee81df2008-05-17 18:14:43 +00002890- Fixed several potential crashes, all caused by specially crafted
2891 __del__ methods exploiting objects in temporarily inconsistent
2892 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002893
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002894- Issue #2115: Important speedup in setting __slot__ attributes. Also

2903 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002904
Georg Brandl3ee81df2008-05-17 18:14:43 +00002905- Issue #2045: Fix an infinite recursion triggered when printing a
2906 subclass of collections.defaultdict, if its default_factory is set
2907 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002908
Christian Heimesf75dbef2008-02-08 00:11:31 +00002909- Fixed a minor memory leak in dictobject.c. The content of the free
2910 list was not freed on interpreter shutdown.
2911
Georg Brandl5a7eca12010-03-21 19:29:04 +00002912- Limit free list of method and built-in function objects to 256

2916 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002917 to compact the internal free lists of pre-allocted ints and floats.
2918
Georg Brandl3ee81df2008-05-17 18:14:43 +00002919- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2920 calls. Python expected the return type int but the fork familie
2921 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002935- Patch #1473257: generator objects gain a gi_code attribute. This is
2936 the same object as the func_code attribute of the function that
2937 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002938
Georg Brandl3ee81df2008-05-17 18:14:43 +00002939- Issue #1920: "while 0" statements were completely removed by the
2940 compiler, even in the presence of an "else" clause, which is
2941 supposed to be run when the condition is false. Now the compiler
2942 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002943

2951
Georg Brandl3ee81df2008-05-17 18:14:43 +00002952- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002953 several extension methods and modules do not work without unicode

Georg Brandl6caad7d2008-01-26 14:19:22 +00002961- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002962 added.
2963
Christian Heimesc94e2b52008-01-14 04:13:37 +00002964- sys.float_info / PyFloat_GetInfo: The floating point information
2965 object was converted from a dict to a specialized structseq object.
2966
Georg Brandl3ee81df2008-05-17 18:14:43 +00002967- Patch #1816: Added sys.flags structseq. It exposes the status of
2968 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002969
Georg Brandl3ee81df2008-05-17 18:14:43 +00002970- Objects/structseq.c: Implemented new structseq representation. The
2971 patch makes structseqs (e.g. the return value of os.stat) more
2972 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002973
Georg Brandl3ee81df2008-05-17 18:14:43 +00002974- Patch #1700288: added a type attribute cache that caches method
2975 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002976
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002977- Bug #1776: __import__() no longer accepts filenames on any platform.
2978 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002979
Georg Brandlaed6c662008-01-07 17:25:53 +00002980- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2981
Georg Brandl3ee81df2008-05-17 18:14:43 +00002982- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2983 envvar and sys.dont_write_bytecode attribute. All these can be set
2984 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002985
Georg Brandl3ee81df2008-05-17 18:14:43 +00002986- Improve some exception messages when Windows fails to load an
2987 extension module. Now we get for example '%1 is not a valid Win32
2988 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002989
Georg Brandl3ee81df2008-05-17 18:14:43 +00002990- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002992- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2993 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002994
Christian Heimes0a8143f2007-12-18 23:22:54 +00002995- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002996 and INF. float("nan"), float("inf") and float("-inf") now work on
2997 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002998
Georg Brandl3ee81df2008-05-17 18:14:43 +00002999- Compiler now generates simpler and faster code for dictionary
3000 literals. The oparg for BUILD_MAP now indicates an estimated
3001 dictionary size. There is a new opcode, STORE_MAP, for adding
3002 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003031- Patch #1739468: Directories and zipfiles containing a __main__.py
3032 file can now be directly executed by passing their name to the
3033 interpreter. The directory/zipfile is automatically inserted as the
3034 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003035
Georg Brandl3ee81df2008-05-17 18:14:43 +00003036- Issue #1265: Fix a problem with sys.settrace, if the tracing
3037 function uses a generator expression when at the same time the
3038 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003039
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003040- sets and frozensets now have an isdisjoint() method.
3041
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003042- optimize the performance of builtin.sum().
3043
Neal Norwitz44f326e2007-10-05 05:29:17 +00003044- Fix warnings found by the new version of the Coverity checker.
3045
Georg Brandl5a7eca12010-03-21 19:29:04 +00003046- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003047 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3048 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003049
Georg Brandl3ee81df2008-05-17 18:14:43 +00003050- Issue #1686386: Tuple's tp_repr did not take into account the
3051 possibility of having a self-referential tuple, which is possible
3052 from C code. Nor did object's tp_str consider that a type's tp_str
3053 could do something that could lead to an inifinite recursion.
3054 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3055 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003056
Georg Brandl3ee81df2008-05-17 18:14:43 +00003057- Issue #1164: It was possible to trigger deadlock when using the
3058 'print' statement to write to a file since the GIL was not released
3059 as needed. Now PyObject_Print() does the right thing along with
3060 various tp_print implementations of the built-in types and those in
3061 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003062
Georg Brandl3ee81df2008-05-17 18:14:43 +00003063- Issue #1147: Exceptions were directly allowing string exceptions in
3064 their throw() method even though string exceptions no longer
3065 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003066
Georg Brandl3ee81df2008-05-17 18:14:43 +00003067- Issue #1096: Prevent a segfault from getting the repr of a very
3068 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003069
Brett Cannon1e534b52007-09-07 04:18:30 +00003070- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003071 PyObject_Call() never calling back out to Python code to trigger
3072 recursion depth updates/checks. Required the creation of a static
3073 RuntimeError instance in case normalizing an exception put the
3074 recursion check value past its limit. Fixes crashers
3075 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003076
Georg Brandl3ee81df2008-05-17 18:14:43 +00003077- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003090- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003091 __*__ attributes. (Some already existed, e.g., __doc__ and
3092 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003093
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003094- Add -3 option to the interpreter to warn about features that are
3095 deprecated and will be changed/removed in Python 3.0.
3096
Georg Brandl2134e752007-05-21 20:34:16 +00003097- Patch #1686487: you can now pass any mapping after '**' in function
3098 calls.
3099
Collin Winter62903052007-05-18 23:11:24 +00003100- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003101 "except E as target:". This is to provide forwards compatibility
3102 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003103
Brett Cannon229cee22007-05-05 01:34:02 +00003104- Deprecate BaseException.message as per PEP 352.
3105
Georg Brandl3ee81df2008-05-17 18:14:43 +00003106- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003107 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003108
Vinay Sajip8549ce32007-05-06 17:53:37 +00003109- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003110 setting a plain string, ie don't expand to single letter identifiers.
3111
Raymond Hettinger13936692007-04-11 18:40:58 +00003112- Request #1191699: Slices can now be pickled.
3113
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003114- Request #1193128: str.translate() now allows a None argument for
3115 translations that only remove characters without re-mapping the
3116 remaining characters.
3117
Georg Brandl5cb76c12007-03-21 09:00:39 +00003118- Patch #1682205: a TypeError while unpacking an iterable is no longer
3119 masked by a generic one with the message "unpack non-sequence".
3120
Neal Norwitzaa754b72007-03-21 06:39:48 +00003121- Remove unused file Python/fmod.c.
3122
Guido van Rossum143b5642007-03-23 04:58:42 +00003123- Bug #1683368: The object.__init__() and object.__new__() methods are
3124 now stricter in rejecting excess arguments. The only time when
3125 either allows excess arguments is when it is not overridden and the
3126 other one is. For backwards compatibility, when both are
3127 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003128 warning later). Also, type.__init__() insists on the same signature
3129 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003130
Georg Brandl3ee81df2008-05-17 18:14:43 +00003131- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3132 object to complex using its __complex__() method before falling back
3133 to the __float__() method. Therefore, the functions in the cmath
3134 module now can operate on objects that define a __complex__()
3135 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003136
Georg Brandl3ee81df2008-05-17 18:14:43 +00003137- Patch #1623563: allow __class__ assignment for classes with
3138 __slots__. The old and the new class are still required to have the
3139 same slot names.

3145 ``object.__reduce_ex__()`` is called with an object that is faking
3146 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003147
Georg Brandl3ee81df2008-05-17 18:14:43 +00003148- Patch #1680015: Don't modify __slots__ tuple if it contains an

3152
Georg Brandl7b9c5552007-03-12 14:30:05 +00003153- Bug #1678647: write a newline after printing an exception in any
3154 case, even when converting the value to a string failed.
3155
Georg Brandl871f1bc2007-03-12 13:17:36 +00003156- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003157 its argument, if it exists. If not, it will work like before. This
3158 allows customizing the output of dir() in the presence of a
3159 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003167- Patch #1491866: change the complex() constructor to allow
3168 parthensized forms. This means complex(repr(x)) now works instead of
3169 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003170
Georg Brandlaa2321b2007-03-07 00:40:28 +00003171- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003172 makes the filenames the warning module prints much more sensible
3173 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003174

3176 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003177 variable is given, but break into the interactive interpreter just
3178 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003186- Patch #1674228: when assigning a slice (old-style), check for the
3187 sq_ass_slice instead of the sq_slice slot.
3188
Georg Brandl3ee81df2008-05-17 18:14:43 +00003189- When printing an unraisable error, don't print exceptions. before
3190 the name. This duplicates the behavior whening normally printing
3191 exceptions.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00003693- Added a timeout parameter to the constructor of other protocols
3694 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3695 work started with create_connection() and timeout in httplib, and
3696 closes patch #723312.
3697
Vinay Sajip8549ce32007-05-06 17:53:37 +00003698- Patch #1676823: Added create_connection() to socket.py, which may be
3699 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00003700 and HTTPSConnection now accept an optional timeout).

3722
Georg Brandlf66b6032007-03-14 08:27:52 +00003723- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00003724 AttributeError instead of an IOError when the server's response
3725 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003726
Georg Brandl3ee81df2008-05-17 18:14:43 +00003727- Patch #957650: "%var%" environment variable references are now

Georg Brandl3ee81df2008-05-17 18:14:43 +00003731- Patch #1429539: pdb now correctly initializes the __main__ module
3732 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003733 correctly now.
3734

Georg Brandl3ee81df2008-05-17 18:14:43 +00003742- Patch #1530482: add pydoc.render_doc() which returns the

Georg Brandl9e6b4702007-03-13 18:15:41 +00003755- Patch #1581073: add a flag to textwrap that prevents the dropping of
3756 whitespace while wrapping.
3757
Georg Brandl92a6bae2007-03-13 17:43:32 +00003758- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003759 are set for invalid interpolation sequences that would lead to
3760 errors on reading back those values.

3803 returned string up to the first NUL character.
3804

3814
Georg Brandl3ee81df2008-05-17 18:14:43 +00003815- unittest now verifies more of its assumptions. In particular,
3816 TestCase and TestSuite subclasses (not instances) are no longer
3817 accepted in TestSuite.addTest(). This should cause no
3818 incompatibility since it never made sense with ordinary subclasses
3819 -- the failure just occurred later, with a more cumbersome
3820 exception.

3830
Georg Brandl3ee81df2008-05-17 18:14:43 +00003831- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00004209 time so that opening a database previously created with the DB_DUP
4210 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4211 opens. Specifically: dictionary assignment to a DB object will
4212 replace all values for a given key when the database allows
4213 duplicate values. DB users should use DB.put(k, v) when they want
4214 to store duplicates; not DB[k] = v.

4221 characters with ASCII value less than 32. Also, it correctly quotes
4222 dots only if they occur on a single line, as opposed to the previous
4223 behavior of quoting dots if they are the second character of any
4224 line.
