946 an existing .py counterpart, override the co_filename attributes of all

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

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

1405 again.

1553
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001554- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1555 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1556 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1557 ``printf`` function, whereas PyString_FromFormat has an independent
1558 implementation and uses "%zd" on all platforms for size_t values.
1559 This makes a difference on win64, where ``printf`` needs "%Id" to display

1655 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1656 for catch_warnings() also led to an improvement in the raising of a

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001679- Issue #2975: When compiling several extension modules with Visual Studio 2008
1680 from the same python interpreter, some environment variables would grow
1681 without limit.
1682

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001720What's New in Python 2.6 beta 3?
1721================================
1722
Barry Warsaw07a4a382008-08-21 01:15:08 +00001723*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001724
1725Core and Builtins
1726-----------------
1727
Guido van Rossumf8402962008-08-20 15:01:50 +00001728- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1729 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1730 extensions do not automatically benefit from the class attribute
1731 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1732 to their tp_flags field if they care. This is a backwards
1733 compatibility feature; in 3.0, all types will use the cache by
1734 default.
1735
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001736- Keyword arguments can now follow starred arguments. (``f(a, *args,
1737 keyword=23)`` is now valid syntax.)
1738
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001739- ctypes function pointers that are COM methods have a boolean True
1740 value again.
1741
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001742- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1743 by denying s# to parse objects that have a releasebuffer procedure,
1744 and introducing s*.
1745
Georg Brandl1e13ea92008-08-11 09:07:59 +00001746- Issue #3537: Fix an assertion failure when an empty but presized dict
1747 object was stored in the freelist.
1748
Mark Dickinsonb6467572008-08-04 21:30:09 +00001749- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1750 ValueError consistently across platforms.
1751
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001752- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1753 (64bit Unix, for example), unichr() would truncate its argument and return
1754 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1755
Neal Norwitze7d8be82008-07-31 17:17:14 +00001756- Apply security patches from Apple.
1757
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001758- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1759 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1760
Antoine Pitrou92f82162008-07-25 22:22:08 +00001761- Issue #1819: function calls with several named parameters are now on
1762 average 35% faster (as measured by pybench).
1763
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001764- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1765 the python debugger steps into a class statement: the free variables (local
1766 variables defined in an outer scope) would be deleted from the outer scope.
1767
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001768- Issue #2620: Overflow checking when allocating or reallocating memory
1769 was not always being done properly in some python types and extension
1770 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1771 all been updated to perform better checks and places in the code that
1772 would previously leak memory on the error path when such an allocation
1773 failed have been fixed.

1777
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001778- Issue #3612: Added some missing basic types in ctypes.wintypes.
1779
Benjamin Petersone977ad42008-08-20 01:42:01 +00001780- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1781 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1782
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001783- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1784 version reported by these tools does not necessarily follow the python
1785 version numbering scheme, so the module is less strict when parsing it.
1786
Nick Coghlanf70385a2008-08-18 12:42:46 +00001787- Issue #2235: Added Py3k warnings for types which will become unhashable
1788 under the stricter __hash__ inheritance rules in 3.0. Several types
1789 which did not meet the rules for hash invariants and were already
1790 unhashable in 3.0 have now been explicitly flagged as unhashable in
1791 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1792 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1793
Brett Cannon88f801d2008-08-18 00:46:22 +00001794- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1795 imported into the module but exposed as part of the module's API.
1796
Brett Cannon7b96f072008-08-18 00:41:11 +00001797- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1798
Brett Cannon46225e72008-08-18 00:36:52 +00001799- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001801- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1802
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001803- Issue #3575: Incremental decoder's decode function now takes bytearray
1804 by using 's*' instead of 't#'.
1805
Jesus Cea585ad8a2009-07-02 15:37:21 +00001806- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001807 fails unicode conversion on 2nd parameter. (windows only)
1808
Facundo Batista94f243a2008-08-17 03:38:39 +00001809- Issue 2464. urllib2 now supports a malformation in the URL received
1810 in a redirect.
1811
Brett Cannonabe423e2008-08-16 21:47:07 +00001812- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001813 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001814
Facundo Batistaeb90b782008-08-16 14:44:07 +00001815- Issue #2776: fixed small issue when handling an URL with double slash
1816 after a 302 response in the case of not going through a proxy.
1817
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001818- Issue #2676: in the email package, content-type parsing was hanging on
1819 pathological input because of quadratic or exponential behaviour of a
1820 regular expression.
1821
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001822- Issue #3476: binary buffered reading through the new "io" library is now
1823 thread-safe.
1824
Brett Cannonbf3157b2008-08-14 05:00:03 +00001825- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1826 since mimetools itself is deprecated. Because modules are cached, all
1827 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1828
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001829- Issue #3134: shutil referenced undefined WindowsError symbol.
1830
Robert Schuppenies14646332008-08-10 11:01:53 +00001831- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1832 menu entries were not deleted.
1833
Brett Cannon83e81842008-08-09 23:30:55 +00001834- Copied the implementation of reduce() to _functools.reduce() to have a
1835 version that did not raise a DeprecationWarning under -3.
1836
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001837- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1838 a MemoryError rather than silently stop the iteration.
1839
Guido van Rossum59ce9012008-08-09 14:55:34 +00001840- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1841 to _sre.compile() will now be rejected. This should not affect anybody
1842 since the re.compile() function never generates invalid re-bytecode.
1843
Skip Montanaroa032bf42008-08-08 22:52:51 +00001844- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1845 upon first access it can be automatically initialized from the csv file if
1846 it wasn't initialized during instantiation.
1847
Brett Cannon3aa2a492008-08-06 22:28:09 +00001848- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1849 the reload() built-in has been removed.
1850
Brett Cannon7e30b672008-08-04 21:52:25 +00001851- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001852 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001863 asking for a specific length. This problem only affected files opened
1864 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001865
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001866- Issue #3449: Update decimal module to use most recent specification
1867 (v. 1.68) and tests (v. 2.58) from IBM.
1868

1916
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001917*Release date: 17-Jul-2008*

1920-----------------
1921
Georg Brandl3e483f62008-07-16 22:57:41 +00001922- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1923 its methods now allow for items objects that can be converted to
1924 an integer using operator.index().
1925
Mark Dickinson64b7e502008-07-16 09:40:03 +00001926- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1927 produced a ValueError instead of giving the correct float.
1928
Eric Smitha5fa5a22008-07-16 00:11:49 +00001929- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1930 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1931
Mark Dickinson7103aa42008-07-15 19:08:33 +00001932- Issue #3008: the float type has a new instance method 'float.hex'
1933 and a new class method 'float.fromhex' to convert floating-point
1934 numbers to and from hexadecimal strings, respectively.
1935
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001936- Issue #2235: __hash__ is once again inherited by default. To allow
1937 collections.Hashable to remain meaningful in the presence of the
1938 default hash implementation (object.__hash__), it is now possible
1939 to explicit block inheritance of hash by setting __hash__=None at
1940 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1941 level.
1942
Nick Coghlanb028f502008-07-13 14:52:36 +00001943- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1944 the parent module cannot be found while performing an absolute import.
1945 This means that an incorrectly defined __package__ attribute will
1946 now only prevent relative imports in that module rather than causing
1947 all imports from that module to fail.
1948
Nick Coghlan14ff9942008-07-08 14:21:42 +00001949- Issue #2517: Allow unicode messages in Exceptions again by correctly

1954 set to a custom object whose write() method happens to install
1955 another file in sys.stdout.

Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001957- Issue #3088: Corrected a race condition in classes derived from
1958 threading.local: the first member set by a thread could be saved in
1959 another thread's dictionary.
1960
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001961- Issue #3004: Minor change to slice.indices(): the start and stop
1962 arguments are now treated identically, making the behaviour easier
1963 to describe and understand. For example, slice(None, -10,
1964 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1965 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1966 10, -1).
1967
Georg Brandl278fc502008-07-19 12:46:12 +00001968- Issue #3219: Calling a function with repeated keyword arguments,
1969 f(a=2, a=23), would not cause a syntax error. This was a regression
1970 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001971
Georg Brandl278fc502008-07-19 12:46:12 +00001972- Issue #2862: Make int and float freelist management consistent with
1973 other freelists. Changes their CompactFreeList apis into
1974 ClearFreeList apis and calls them via gc.collect().

1980 api functions without holding the GIL, which could lead to a fatal
1981 error when they failed.
1982
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001983- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002008- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2009 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002010 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002011 content-length. The problem had been corrected in the 2.4 branch, but never
2012 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002027- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2028 handling is now the same as that of other special attributes like __name__).

Georg Brandl3ee81df2008-05-17 18:14:43 +00002482- Issue #1631171: Re-implement the 'warnings' module in C (the
2483 original Python code has been kept as backup). This will allow for
2484 using the 'warning's machinery in such places as the parser where
2485 use of pure Python code is not possible. Both the ``showarning()``
2486 and ``formatwarning()`` gain an optional 'line' argument which is
2487 not called by default for backwards-compatibility reasons. Setting
2488 ``warnings.showwarning()`` to an implementation that lacks support
2489 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002552- Issue #2550: The approach used by client/server code for obtaining
2553 ports to listen on in network-oriented tests has been refined in an
2554 effort to facilitate running multiple instances of the entire
2555 regression test suite in parallel without issue.
2556 test_support.bind_port() has been fixed such that it will always
2557 return a unique port -- which wasn't always the case with the
2558 previous implementation, especially if socket options had been set
2559 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2560 new implementation of bind_port() will actually raise an exception
2561 if it is passed an AF_INET/SOCK_STREAM socket with either the
2562 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2563 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2564 the socket it's been passed. This currently only applies to
2565 Windows. This option prevents any other sockets from binding to the
2566 host/port we've bound to, thus removing the possibility of the
2567 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2568 when a second SOCK_STREAM socket binds and accepts to a host/port
2569 that's already been bound by another socket. The optional preferred
2570 port parameter to bind_port() has been removed. Under no
2571 circumstances should tests be hard coding ports!
2572
2573 test_support.find_unused_port() has also been introduced, which will
2574 pass a temporary socket object to bind_port() in order to obtain an
2575 unused port. The temporary socket object is then closed and
2576 deleted, and the port is returned. This method should only be used
2577 for obtaining an unused port in order to pass to an external program
2578 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2579 a parameter to a server-oriented class that doesn't give you direct
2580 access to the underlying socket used.
2581
2582 Finally, test_support.HOST has been introduced, which should be used
2583 for the host argument of any relevant socket calls (i.e. bind and
2584 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002585
2586 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002587 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002588 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2589 test_asynchat and test_socket_ssl.
2590
Georg Brandl3ee81df2008-05-17 18:14:43 +00002591 It is now possible for multiple instances of the regression test
2592 suite to run in parallel without issue.

2860
Fred Drakea8ee94b2008-03-01 02:45:07 +00002861- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002862 644. The mode is now inherited from the py file.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00002868- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002869 issue 215555 for a discussion.
2870
Eric Smitha73fbe72008-02-23 03:09:44 +00002871- Added the future_builtins module, which contains hex() and oct().
2872 These are the PEP 3127 version of these functions, designed to be
2873 compatible with the hex() and oct() builtins from Python 3.0. They
2874 differ slightly in their output formats from the existing, unchanged
2875 Python 2.6 builtins. The expected usage of the future_builtins
2876 module is:
2877 from future_builtins import hex, oct
2878
Eric Smith7ef40bf2008-02-20 23:34:22 +00002879- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2880 exponents for exponents with absolute value < 100. Follows C99
2881 standard. This is a change on Windows, which would use 3 digits.
2882 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2883 so that any alterations it does to the resulting string will be
2884 available in stringlib/formatter.h (for float.__format__).
2885
Eric Smith5a3c1352008-02-19 13:21:56 +00002886- Implemented PEP 3101, Advanced String Formatting. This adds a new
2887 builtin format(); a format() method for str and unicode; a
2888 __format__() method to object, str, unicode, int, long, float, and
2889 datetime; the class string.Formatter; and the C API
2890 PyObject_Format().
2891
Georg Brandl3ee81df2008-05-17 18:14:43 +00002892- Fixed several potential crashes, all caused by specially crafted
2893 __del__ methods exploiting objects in temporarily inconsistent
2894 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002895
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002896- Issue #2115: Important speedup in setting __slot__ attributes. Also

2905 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002906
Georg Brandl3ee81df2008-05-17 18:14:43 +00002907- Issue #2045: Fix an infinite recursion triggered when printing a

2909 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002910
Christian Heimesf75dbef2008-02-08 00:11:31 +00002911- Fixed a minor memory leak in dictobject.c. The content of the free

2918 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002919 to compact the internal free lists of pre-allocted ints and floats.
2920
Georg Brandl3ee81df2008-05-17 18:14:43 +00002921- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2922 calls. Python expected the return type int but the fork familie
2923 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002937- Patch #1473257: generator objects gain a gi_code attribute. This is
2938 the same object as the func_code attribute of the function that
2939 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002940
Georg Brandl3ee81df2008-05-17 18:14:43 +00002941- Issue #1920: "while 0" statements were completely removed by the
2942 compiler, even in the presence of an "else" clause, which is
2943 supposed to be run when the condition is false. Now the compiler
2944 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002945

2953
Georg Brandl3ee81df2008-05-17 18:14:43 +00002954- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002955 several extension methods and modules do not work without unicode

Georg Brandl6caad7d2008-01-26 14:19:22 +00002963- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002964 added.
2965
Christian Heimesc94e2b52008-01-14 04:13:37 +00002966- sys.float_info / PyFloat_GetInfo: The floating point information
2967 object was converted from a dict to a specialized structseq object.
2968
Georg Brandl3ee81df2008-05-17 18:14:43 +00002969- Patch #1816: Added sys.flags structseq. It exposes the status of
2970 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002971
Georg Brandl3ee81df2008-05-17 18:14:43 +00002972- Objects/structseq.c: Implemented new structseq representation. The
2973 patch makes structseqs (e.g. the return value of os.stat) more
2974 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002975
Georg Brandl3ee81df2008-05-17 18:14:43 +00002976- Patch #1700288: added a type attribute cache that caches method
2977 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002978
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002979- Bug #1776: __import__() no longer accepts filenames on any platform.
2980 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002981
Georg Brandlaed6c662008-01-07 17:25:53 +00002982- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2983
Georg Brandl3ee81df2008-05-17 18:14:43 +00002984- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2985 envvar and sys.dont_write_bytecode attribute. All these can be set
2986 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002987
Georg Brandl3ee81df2008-05-17 18:14:43 +00002988- Improve some exception messages when Windows fails to load an
2989 extension module. Now we get for example '%1 is not a valid Win32
2990 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002991
Georg Brandl3ee81df2008-05-17 18:14:43 +00002992- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002994- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2995 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002996
Christian Heimes0a8143f2007-12-18 23:22:54 +00002997- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002998 and INF. float("nan"), float("inf") and float("-inf") now work on
2999 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003000
Georg Brandl3ee81df2008-05-17 18:14:43 +00003001- Compiler now generates simpler and faster code for dictionary
3002 literals. The oparg for BUILD_MAP now indicates an estimated
3003 dictionary size. There is a new opcode, STORE_MAP, for adding
3004 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003033- Patch #1739468: Directories and zipfiles containing a __main__.py
3034 file can now be directly executed by passing their name to the
3035 interpreter. The directory/zipfile is automatically inserted as the
3036 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003037
Georg Brandl3ee81df2008-05-17 18:14:43 +00003038- Issue #1265: Fix a problem with sys.settrace, if the tracing
3039 function uses a generator expression when at the same time the
3040 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003041
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003042- sets and frozensets now have an isdisjoint() method.
3043
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003044- optimize the performance of builtin.sum().
3045
Neal Norwitz44f326e2007-10-05 05:29:17 +00003046- Fix warnings found by the new version of the Coverity checker.
3047
Georg Brandl5a7eca12010-03-21 19:29:04 +00003048- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003049 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3050 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003051
Georg Brandl3ee81df2008-05-17 18:14:43 +00003052- Issue #1686386: Tuple's tp_repr did not take into account the
3053 possibility of having a self-referential tuple, which is possible
3054 from C code. Nor did object's tp_str consider that a type's tp_str
3055 could do something that could lead to an inifinite recursion.
3056 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3057 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003058
Georg Brandl3ee81df2008-05-17 18:14:43 +00003059- Issue #1164: It was possible to trigger deadlock when using the
3060 'print' statement to write to a file since the GIL was not released
3061 as needed. Now PyObject_Print() does the right thing along with
3062 various tp_print implementations of the built-in types and those in
3063 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003064
Georg Brandl3ee81df2008-05-17 18:14:43 +00003065- Issue #1147: Exceptions were directly allowing string exceptions in
3066 their throw() method even though string exceptions no longer
3067 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003068
Georg Brandl3ee81df2008-05-17 18:14:43 +00003069- Issue #1096: Prevent a segfault from getting the repr of a very
3070 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003071
Brett Cannon1e534b52007-09-07 04:18:30 +00003072- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003073 PyObject_Call() never calling back out to Python code to trigger
3074 recursion depth updates/checks. Required the creation of a static
3075 RuntimeError instance in case normalizing an exception put the
3076 recursion check value past its limit. Fixes crashers
3077 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003078
Georg Brandl3ee81df2008-05-17 18:14:43 +00003079- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003092- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003093 __*__ attributes. (Some already existed, e.g., __doc__ and
3094 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003095
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003096- Add -3 option to the interpreter to warn about features that are
3097 deprecated and will be changed/removed in Python 3.0.
3098
Georg Brandl2134e752007-05-21 20:34:16 +00003099- Patch #1686487: you can now pass any mapping after '**' in function
3100 calls.
3101
Collin Winter62903052007-05-18 23:11:24 +00003102- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003103 "except E as target:". This is to provide forwards compatibility
3104 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003105
Brett Cannon229cee22007-05-05 01:34:02 +00003106- Deprecate BaseException.message as per PEP 352.
3107
Georg Brandl3ee81df2008-05-17 18:14:43 +00003108- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003109 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003110
Vinay Sajip8549ce32007-05-06 17:53:37 +00003111- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003112 setting a plain string, ie don't expand to single letter identifiers.
3113
Raymond Hettinger13936692007-04-11 18:40:58 +00003114- Request #1191699: Slices can now be pickled.
3115
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003116- Request #1193128: str.translate() now allows a None argument for
3117 translations that only remove characters without re-mapping the
3118 remaining characters.
3119
Georg Brandl5cb76c12007-03-21 09:00:39 +00003120- Patch #1682205: a TypeError while unpacking an iterable is no longer
3121 masked by a generic one with the message "unpack non-sequence".
3122
Neal Norwitzaa754b72007-03-21 06:39:48 +00003123- Remove unused file Python/fmod.c.
3124
Guido van Rossum143b5642007-03-23 04:58:42 +00003125- Bug #1683368: The object.__init__() and object.__new__() methods are
3126 now stricter in rejecting excess arguments. The only time when
3127 either allows excess arguments is when it is not overridden and the
3128 other one is. For backwards compatibility, when both are
3129 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003130 warning later). Also, type.__init__() insists on the same signature
3131 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003132
Georg Brandl3ee81df2008-05-17 18:14:43 +00003133- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3134 object to complex using its __complex__() method before falling back
3135 to the __float__() method. Therefore, the functions in the cmath
3136 module now can operate on objects that define a __complex__()
3137 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003138
Georg Brandl3ee81df2008-05-17 18:14:43 +00003139- Patch #1623563: allow __class__ assignment for classes with
3140 __slots__. The old and the new class are still required to have the
3141 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003142

3147 ``object.__reduce_ex__()`` is called with an object that is faking
3148 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003149
Georg Brandl3ee81df2008-05-17 18:14:43 +00003150- Patch #1680015: Don't modify __slots__ tuple if it contains an

3154
Georg Brandl7b9c5552007-03-12 14:30:05 +00003155- Bug #1678647: write a newline after printing an exception in any
3156 case, even when converting the value to a string failed.
3157
Georg Brandl871f1bc2007-03-12 13:17:36 +00003158- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003159 its argument, if it exists. If not, it will work like before. This
3160 allows customizing the output of dir() in the presence of a
3161 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00003163- Patch #922167: Python no longer segfaults when faced with infinitely
3164 self-recursive reload() calls (as reported by bug #742342).
3165
Georg Brandl3ee81df2008-05-17 18:14:43 +00003166- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00003169- Patch #1491866: change the complex() constructor to allow
3170 parthensized forms. This means complex(repr(x)) now works instead of
3171 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003172
Georg Brandlaa2321b2007-03-07 00:40:28 +00003173- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003174 makes the filenames the warning module prints much more sensible
3175 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003176

3178 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003179 variable is given, but break into the interactive interpreter just
3180 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003188- Patch #1674228: when assigning a slice (old-style), check for the
3189 sq_ass_slice instead of the sq_slice slot.
3190
Georg Brandl3ee81df2008-05-17 18:14:43 +00003191- When printing an unraisable error, don't print exceptions. before
3192 the name. This duplicates the behavior whening normally printing
3193 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00003194

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00003695- Added a timeout parameter to the constructor of other protocols
3696 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3697 work started with create_connection() and timeout in httplib, and
3698 closes patch #723312.
3699
Vinay Sajip8549ce32007-05-06 17:53:37 +00003700- Patch #1676823: Added create_connection() to socket.py, which may be

Georg Brandl3ee81df2008-05-17 18:14:43 +00003726 AttributeError instead of an IOError when the server's response
3727 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003728

Georg Brandl3ee81df2008-05-17 18:14:43 +00003733- Patch #1429539: pdb now correctly initializes the __main__ module
3734 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003735 correctly now.
3736

Georg Brandl3ee81df2008-05-17 18:14:43 +00003744- Patch #1530482: add pydoc.render_doc() which returns the

Georg Brandl9e6b4702007-03-13 18:15:41 +00003757- Patch #1581073: add a flag to textwrap that prevents the dropping of

3759
Georg Brandl92a6bae2007-03-13 17:43:32 +00003760- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003761 are set for invalid interpolation sequences that would lead to
3762 errors on reading back those values.

3805 returned string up to the first NUL character.

3816
Georg Brandl3ee81df2008-05-17 18:14:43 +00003817- unittest now verifies more of its assumptions. In particular,
3818 TestCase and TestSuite subclasses (not instances) are no longer
3819 accepted in TestSuite.addTest(). This should cause no
3820 incompatibility since it never made sense with ordinary subclasses
3821 -- the failure just occurred later, with a more cumbersome
3822 exception.

3832
Georg Brandl3ee81df2008-05-17 18:14:43 +00003833- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00004211 time so that opening a database previously created with the DB_DUP
4212 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4213 opens. Specifically: dictionary assignment to a DB object will
4214 replace all values for a given key when the database allows
4215 duplicate values. DB users should use DB.put(k, v) when they want
4216 to store duplicates; not DB[k] = v.

4223 characters with ASCII value less than 32. Also, it correctly quotes
4224 dots only if they occur on a single line, as opposed to the previous
4225 behavior of quoting dots if they are the second character of any
4226 line.
