1357What's New in Python 2.6.1
1358==========================
1359
1360*Release date: 04-Dec-2008*
1361
1362Core and Builtins
1363-----------------
1364
1365- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1366 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1367 instead of throwing a MemoryError.
1368
1369- Issue #4367: Python would segfault during compiling when the unicodedata
1370 module couldn't be imported and \N escapes were present.
1371
1372- Issue #4348: Some bytearray methods returned that didn't cause any change to
1373 the bytearray, returned the same bytearray instead of a copy.
1374
1375- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1376
1377- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1378
1379- Issue #4048: The parser module now correctly validates relative imports.
1380
1381- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

1386
1387- Issue #4209: Enabling unicode_literals and the print_function in the same
1388 __future__ import didn't work.
1389
1390- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1391 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1392 really executed because I cannot move to such directory on win2k)
1393
1394- Issue #4069: When set.remove(element) is used with a set element, the element
1395 is temporarily replaced with an equivalent frozenset. But the eventual
1396 KeyError would always report the empty frozenset([]) as the missing key. Now
1397 it correctly refers to the initial element.
1398
1399- Fixed C99 style comments in several files. Python is now C89 compatible
1400 again.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001549- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1550 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1551 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1552 ``printf`` function, whereas PyString_FromFormat has an independent
1553 implementation and uses "%zd" on all platforms for size_t values.
1554 This makes a difference on win64, where ``printf`` needs "%Id" to display

1650 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1651 for catch_warnings() also led to an improvement in the raising of a

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001715What's New in Python 2.6 beta 3?
1716================================
1717
Barry Warsaw07a4a382008-08-21 01:15:08 +00001718*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001719
1720Core and Builtins
1721-----------------
1722
Guido van Rossumf8402962008-08-20 15:01:50 +00001723- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1724 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1725 extensions do not automatically benefit from the class attribute
1726 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1727 to their tp_flags field if they care. This is a backwards
1728 compatibility feature; in 3.0, all types will use the cache by
1729 default.
1730
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001731- Keyword arguments can now follow starred arguments. (``f(a, *args,
1732 keyword=23)`` is now valid syntax.)
1733
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001734- ctypes function pointers that are COM methods have a boolean True
1735 value again.
1736
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001737- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1738 by denying s# to parse objects that have a releasebuffer procedure,
1739 and introducing s*.
1740
Georg Brandl1e13ea92008-08-11 09:07:59 +00001741- Issue #3537: Fix an assertion failure when an empty but presized dict
1742 object was stored in the freelist.
1743
Mark Dickinsonb6467572008-08-04 21:30:09 +00001744- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1745 ValueError consistently across platforms.
1746
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001747- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1748 (64bit Unix, for example), unichr() would truncate its argument and return
1749 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1750
Neal Norwitze7d8be82008-07-31 17:17:14 +00001751- Apply security patches from Apple.
1752
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001753- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1754 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1755
Antoine Pitrou92f82162008-07-25 22:22:08 +00001756- Issue #1819: function calls with several named parameters are now on
1757 average 35% faster (as measured by pybench).
1758
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001759- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1760 the python debugger steps into a class statement: the free variables (local
1761 variables defined in an outer scope) would be deleted from the outer scope.
1762
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001763- Issue #2620: Overflow checking when allocating or reallocating memory
1764 was not always being done properly in some python types and extension
1765 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1766 all been updated to perform better checks and places in the code that
1767 would previously leak memory on the error path when such an allocation
1768 failed have been fixed.

1772
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001773- Issue #3612: Added some missing basic types in ctypes.wintypes.
1774
Benjamin Petersone977ad42008-08-20 01:42:01 +00001775- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1776 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1777
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001778- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1779 version reported by these tools does not necessarily follow the python
1780 version numbering scheme, so the module is less strict when parsing it.
1781
Nick Coghlanf70385a2008-08-18 12:42:46 +00001782- Issue #2235: Added Py3k warnings for types which will become unhashable
1783 under the stricter __hash__ inheritance rules in 3.0. Several types
1784 which did not meet the rules for hash invariants and were already
1785 unhashable in 3.0 have now been explicitly flagged as unhashable in
1786 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1787 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1788
Brett Cannon88f801d2008-08-18 00:46:22 +00001789- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1790 imported into the module but exposed as part of the module's API.
1791
Brett Cannon7b96f072008-08-18 00:41:11 +00001792- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1793
Brett Cannon46225e72008-08-18 00:36:52 +00001794- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001796- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1797
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001798- Issue #3575: Incremental decoder's decode function now takes bytearray
1799 by using 's*' instead of 't#'.
1800
Jesus Cea585ad8a2009-07-02 15:37:21 +00001801- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001802 fails unicode conversion on 2nd parameter. (windows only)
1803
Facundo Batista94f243a2008-08-17 03:38:39 +00001804- Issue 2464. urllib2 now supports a malformation in the URL received
1805 in a redirect.
1806
Brett Cannonabe423e2008-08-16 21:47:07 +00001807- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001808 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001809
Facundo Batistaeb90b782008-08-16 14:44:07 +00001810- Issue #2776: fixed small issue when handling an URL with double slash
1811 after a 302 response in the case of not going through a proxy.
1812
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001813- Issue #2676: in the email package, content-type parsing was hanging on
1814 pathological input because of quadratic or exponential behaviour of a
1815 regular expression.
1816
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001817- Issue #3476: binary buffered reading through the new "io" library is now
1818 thread-safe.
1819
Brett Cannonbf3157b2008-08-14 05:00:03 +00001820- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1821 since mimetools itself is deprecated. Because modules are cached, all
1822 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1823
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001824- Issue #3134: shutil referenced undefined WindowsError symbol.
1825
Robert Schuppenies14646332008-08-10 11:01:53 +00001826- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1827 menu entries were not deleted.
1828
Brett Cannon83e81842008-08-09 23:30:55 +00001829- Copied the implementation of reduce() to _functools.reduce() to have a
1830 version that did not raise a DeprecationWarning under -3.
1831
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001832- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1833 a MemoryError rather than silently stop the iteration.
1834
Guido van Rossum59ce9012008-08-09 14:55:34 +00001835- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1836 to _sre.compile() will now be rejected. This should not affect anybody
1837 since the re.compile() function never generates invalid re-bytecode.
1838
Skip Montanaroa032bf42008-08-08 22:52:51 +00001839- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1840 upon first access it can be automatically initialized from the csv file if
1841 it wasn't initialized during instantiation.
1842
Brett Cannon3aa2a492008-08-06 22:28:09 +00001843- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1844 the reload() built-in has been removed.
1845
Brett Cannon7e30b672008-08-04 21:52:25 +00001846- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001847 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001858 asking for a specific length. This problem only affected files opened
1859 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001860
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001861- Issue #3449: Update decimal module to use most recent specification
1862 (v. 1.68) and tests (v. 2.58) from IBM.
1863

1910================================
1911
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001912*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001914Core and Builtins
1915-----------------
1916
Georg Brandl3e483f62008-07-16 22:57:41 +00001917- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1918 its methods now allow for items objects that can be converted to
1919 an integer using operator.index().
1920
Mark Dickinson64b7e502008-07-16 09:40:03 +00001921- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1922 produced a ValueError instead of giving the correct float.
1923
Eric Smitha5fa5a22008-07-16 00:11:49 +00001924- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1925 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1926
Mark Dickinson7103aa42008-07-15 19:08:33 +00001927- Issue #3008: the float type has a new instance method 'float.hex'
1928 and a new class method 'float.fromhex' to convert floating-point
1929 numbers to and from hexadecimal strings, respectively.
1930
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001931- Issue #2235: __hash__ is once again inherited by default. To allow
1932 collections.Hashable to remain meaningful in the presence of the
1933 default hash implementation (object.__hash__), it is now possible
1934 to explicit block inheritance of hash by setting __hash__=None at
1935 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1936 level.
1937
Nick Coghlanb028f502008-07-13 14:52:36 +00001938- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1939 the parent module cannot be found while performing an absolute import.
1940 This means that an incorrectly defined __package__ attribute will
1941 now only prevent relative imports in that module rather than causing
1942 all imports from that module to fail.
1943
Nick Coghlan14ff9942008-07-08 14:21:42 +00001944- Issue #2517: Allow unicode messages in Exceptions again by correctly

1949 set to a custom object whose write() method happens to install
1950 another file in sys.stdout.
1951
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001952- Issue #3088: Corrected a race condition in classes derived from
1953 threading.local: the first member set by a thread could be saved in
1954 another thread's dictionary.
1955
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001956- Issue #3004: Minor change to slice.indices(): the start and stop
1957 arguments are now treated identically, making the behaviour easier
1958 to describe and understand. For example, slice(None, -10,
1959 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1960 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1961 10, -1).
1962
Georg Brandl278fc502008-07-19 12:46:12 +00001963- Issue #3219: Calling a function with repeated keyword arguments,
1964 f(a=2, a=23), would not cause a syntax error. This was a regression
1965 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001966
Georg Brandl278fc502008-07-19 12:46:12 +00001967- Issue #2862: Make int and float freelist management consistent with
1968 other freelists. Changes their CompactFreeList apis into
1969 ClearFreeList apis and calls them via gc.collect().

1975 api functions without holding the GIL, which could lead to a fatal
1976 error when they failed.
1977
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001978- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002003- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2004 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002005 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002006 content-length. The problem had been corrected in the 2.4 branch, but never
2007 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002022- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2023 handling is now the same as that of other special attributes like __name__).

Georg Brandl3ee81df2008-05-17 18:14:43 +00002477- Issue #1631171: Re-implement the 'warnings' module in C (the
2478 original Python code has been kept as backup). This will allow for
2479 using the 'warning's machinery in such places as the parser where
2480 use of pure Python code is not possible. Both the ``showarning()``
2481 and ``formatwarning()`` gain an optional 'line' argument which is
2482 not called by default for backwards-compatibility reasons. Setting
2483 ``warnings.showwarning()`` to an implementation that lacks support
2484 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002547- Issue #2550: The approach used by client/server code for obtaining
2548 ports to listen on in network-oriented tests has been refined in an
2549 effort to facilitate running multiple instances of the entire
2550 regression test suite in parallel without issue.
2551 test_support.bind_port() has been fixed such that it will always
2552 return a unique port -- which wasn't always the case with the
2553 previous implementation, especially if socket options had been set
2554 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2555 new implementation of bind_port() will actually raise an exception
2556 if it is passed an AF_INET/SOCK_STREAM socket with either the
2557 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2558 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2559 the socket it's been passed. This currently only applies to
2560 Windows. This option prevents any other sockets from binding to the
2561 host/port we've bound to, thus removing the possibility of the
2562 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2563 when a second SOCK_STREAM socket binds and accepts to a host/port
2564 that's already been bound by another socket. The optional preferred
2565 port parameter to bind_port() has been removed. Under no
2566 circumstances should tests be hard coding ports!
2567
2568 test_support.find_unused_port() has also been introduced, which will
2569 pass a temporary socket object to bind_port() in order to obtain an
2570 unused port. The temporary socket object is then closed and
2571 deleted, and the port is returned. This method should only be used
2572 for obtaining an unused port in order to pass to an external program
2573 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2574 a parameter to a server-oriented class that doesn't give you direct
2575 access to the underlying socket used.
2576
2577 Finally, test_support.HOST has been introduced, which should be used
2578 for the host argument of any relevant socket calls (i.e. bind and
2579 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002580
2581 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002582 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002583 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2584 test_asynchat and test_socket_ssl.
2585
Georg Brandl3ee81df2008-05-17 18:14:43 +00002586 It is now possible for multiple instances of the regression test
2587 suite to run in parallel without issue.

2854-----------------
2855
Fred Drakea8ee94b2008-03-01 02:45:07 +00002856- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002857 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002862
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002863- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002864 issue 215555 for a discussion.
2865
Eric Smitha73fbe72008-02-23 03:09:44 +00002866- Added the future_builtins module, which contains hex() and oct().
2867 These are the PEP 3127 version of these functions, designed to be
2868 compatible with the hex() and oct() builtins from Python 3.0. They
2869 differ slightly in their output formats from the existing, unchanged
2870 Python 2.6 builtins. The expected usage of the future_builtins
2871 module is:
2872 from future_builtins import hex, oct
2873
Eric Smith7ef40bf2008-02-20 23:34:22 +00002874- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2875 exponents for exponents with absolute value < 100. Follows C99
2876 standard. This is a change on Windows, which would use 3 digits.
2877 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2878 so that any alterations it does to the resulting string will be
2879 available in stringlib/formatter.h (for float.__format__).
2880
Eric Smith5a3c1352008-02-19 13:21:56 +00002881- Implemented PEP 3101, Advanced String Formatting. This adds a new
2882 builtin format(); a format() method for str and unicode; a
2883 __format__() method to object, str, unicode, int, long, float, and
2884 datetime; the class string.Formatter; and the C API
2885 PyObject_Format().
2886
Georg Brandl3ee81df2008-05-17 18:14:43 +00002887- Fixed several potential crashes, all caused by specially crafted
2888 __del__ methods exploiting objects in temporarily inconsistent
2889 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002890
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002891- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002892 prevent a possible crash: an Abstract Base Class would try to access
2893 a slot on a registered virtual subclass.

2900 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002901
Georg Brandl3ee81df2008-05-17 18:14:43 +00002902- Issue #2045: Fix an infinite recursion triggered when printing a
2903 subclass of collections.defaultdict, if its default_factory is set
2904 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002905
Christian Heimesf75dbef2008-02-08 00:11:31 +00002906- Fixed a minor memory leak in dictobject.c. The content of the free

2913 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002914 to compact the internal free lists of pre-allocted ints and floats.
2915
Georg Brandl3ee81df2008-05-17 18:14:43 +00002916- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2917 calls. Python expected the return type int but the fork familie
2918 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002932- Patch #1473257: generator objects gain a gi_code attribute. This is
2933 the same object as the func_code attribute of the function that
2934 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002935
Georg Brandl3ee81df2008-05-17 18:14:43 +00002936- Issue #1920: "while 0" statements were completely removed by the
2937 compiler, even in the presence of an "else" clause, which is
2938 supposed to be run when the condition is false. Now the compiler
2939 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002940

Georg Brandl6caad7d2008-01-26 14:19:22 +00002958- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002959 added.
2960
Christian Heimesc94e2b52008-01-14 04:13:37 +00002961- sys.float_info / PyFloat_GetInfo: The floating point information
2962 object was converted from a dict to a specialized structseq object.
2963
Georg Brandl3ee81df2008-05-17 18:14:43 +00002964- Patch #1816: Added sys.flags structseq. It exposes the status of
2965 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002966
Georg Brandl3ee81df2008-05-17 18:14:43 +00002967- Objects/structseq.c: Implemented new structseq representation. The
2968 patch makes structseqs (e.g. the return value of os.stat) more
2969 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002970
Georg Brandl3ee81df2008-05-17 18:14:43 +00002971- Patch #1700288: added a type attribute cache that caches method
2972 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002973
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002974- Bug #1776: __import__() no longer accepts filenames on any platform.
2975 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002976
Georg Brandlaed6c662008-01-07 17:25:53 +00002977- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2978
Georg Brandl3ee81df2008-05-17 18:14:43 +00002979- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2980 envvar and sys.dont_write_bytecode attribute. All these can be set
2981 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002982
Georg Brandl3ee81df2008-05-17 18:14:43 +00002983- Improve some exception messages when Windows fails to load an
2984 extension module. Now we get for example '%1 is not a valid Win32
2985 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002986
Georg Brandl3ee81df2008-05-17 18:14:43 +00002987- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002989- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2990 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002991
Christian Heimes0a8143f2007-12-18 23:22:54 +00002992- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002993 and INF. float("nan"), float("inf") and float("-inf") now work on
2994 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002995
Georg Brandl3ee81df2008-05-17 18:14:43 +00002996- Compiler now generates simpler and faster code for dictionary
2997 literals. The oparg for BUILD_MAP now indicates an estimated
2998 dictionary size. There is a new opcode, STORE_MAP, for adding
2999 entries to the dictionary.

3011
Nick Coghlanef01d822007-12-03 12:55:17 +00003012- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00003028- Patch #1739468: Directories and zipfiles containing a __main__.py
3029 file can now be directly executed by passing their name to the
3030 interpreter. The directory/zipfile is automatically inserted as the
3031 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003032
Georg Brandl3ee81df2008-05-17 18:14:43 +00003033- Issue #1265: Fix a problem with sys.settrace, if the tracing
3034 function uses a generator expression when at the same time the
3035 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003036
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003037- sets and frozensets now have an isdisjoint() method.
3038
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003039- optimize the performance of builtin.sum().
3040
Neal Norwitz44f326e2007-10-05 05:29:17 +00003041- Fix warnings found by the new version of the Coverity checker.
3042
Georg Brandl5a7eca12010-03-21 19:29:04 +00003043- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003044 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3045 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003046
Georg Brandl3ee81df2008-05-17 18:14:43 +00003047- Issue #1686386: Tuple's tp_repr did not take into account the
3048 possibility of having a self-referential tuple, which is possible
3049 from C code. Nor did object's tp_str consider that a type's tp_str
3050 could do something that could lead to an inifinite recursion.
3051 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3052 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003053
Georg Brandl3ee81df2008-05-17 18:14:43 +00003054- Issue #1164: It was possible to trigger deadlock when using the
3055 'print' statement to write to a file since the GIL was not released
3056 as needed. Now PyObject_Print() does the right thing along with
3057 various tp_print implementations of the built-in types and those in
3058 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003059
Georg Brandl3ee81df2008-05-17 18:14:43 +00003060- Issue #1147: Exceptions were directly allowing string exceptions in
3061 their throw() method even though string exceptions no longer
3062 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003063
Georg Brandl3ee81df2008-05-17 18:14:43 +00003064- Issue #1096: Prevent a segfault from getting the repr of a very
3065 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003066
Brett Cannon1e534b52007-09-07 04:18:30 +00003067- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003068 PyObject_Call() never calling back out to Python code to trigger
3069 recursion depth updates/checks. Required the creation of a static
3070 RuntimeError instance in case normalizing an exception put the
3071 recursion check value past its limit. Fixes crashers
3072 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003073
Georg Brandl3ee81df2008-05-17 18:14:43 +00003074- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003087- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003088 __*__ attributes. (Some already existed, e.g., __doc__ and
3089 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003090
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003091- Add -3 option to the interpreter to warn about features that are
3092 deprecated and will be changed/removed in Python 3.0.
3093
Georg Brandl2134e752007-05-21 20:34:16 +00003094- Patch #1686487: you can now pass any mapping after '**' in function
3095 calls.
3096
Collin Winter62903052007-05-18 23:11:24 +00003097- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003098 "except E as target:". This is to provide forwards compatibility
3099 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003100
Brett Cannon229cee22007-05-05 01:34:02 +00003101- Deprecate BaseException.message as per PEP 352.
3102
Georg Brandl3ee81df2008-05-17 18:14:43 +00003103- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003104 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003105
Vinay Sajip8549ce32007-05-06 17:53:37 +00003106- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003107 setting a plain string, ie don't expand to single letter identifiers.
3108
Raymond Hettinger13936692007-04-11 18:40:58 +00003109- Request #1191699: Slices can now be pickled.
3110
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003111- Request #1193128: str.translate() now allows a None argument for
3112 translations that only remove characters without re-mapping the
3113 remaining characters.
3114
Georg Brandl5cb76c12007-03-21 09:00:39 +00003115- Patch #1682205: a TypeError while unpacking an iterable is no longer
3116 masked by a generic one with the message "unpack non-sequence".
3117
Neal Norwitzaa754b72007-03-21 06:39:48 +00003118- Remove unused file Python/fmod.c.
3119
Guido van Rossum143b5642007-03-23 04:58:42 +00003120- Bug #1683368: The object.__init__() and object.__new__() methods are
3121 now stricter in rejecting excess arguments. The only time when
3122 either allows excess arguments is when it is not overridden and the
3123 other one is. For backwards compatibility, when both are
3124 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003125 warning later). Also, type.__init__() insists on the same signature
3126 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003127
Georg Brandl3ee81df2008-05-17 18:14:43 +00003128- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3129 object to complex using its __complex__() method before falling back
3130 to the __float__() method. Therefore, the functions in the cmath
3131 module now can operate on objects that define a __complex__()
3132 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003133
Georg Brandl3ee81df2008-05-17 18:14:43 +00003134- Patch #1623563: allow __class__ assignment for classes with
3135 __slots__. The old and the new class are still required to have the
3136 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003137

3142 ``object.__reduce_ex__()`` is called with an object that is faking
3143 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003144
Georg Brandl3ee81df2008-05-17 18:14:43 +00003145- Patch #1680015: Don't modify __slots__ tuple if it contains an

3149
Georg Brandl7b9c5552007-03-12 14:30:05 +00003150- Bug #1678647: write a newline after printing an exception in any
3151 case, even when converting the value to a string failed.
3152
Georg Brandl871f1bc2007-03-12 13:17:36 +00003153- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003154 its argument, if it exists. If not, it will work like before. This
3155 allows customizing the output of dir() in the presence of a
3156 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00003158- Patch #922167: Python no longer segfaults when faced with infinitely
3159 self-recursive reload() calls (as reported by bug #742342).
3160
Georg Brandl3ee81df2008-05-17 18:14:43 +00003161- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00003164- Patch #1491866: change the complex() constructor to allow
3165 parthensized forms. This means complex(repr(x)) now works instead of
3166 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003167
Georg Brandlaa2321b2007-03-07 00:40:28 +00003168- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003169 makes the filenames the warning module prints much more sensible
3170 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003171

3173 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003174 variable is given, but break into the interactive interpreter just
3175 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003183- Patch #1674228: when assigning a slice (old-style), check for the
3184 sq_ass_slice instead of the sq_slice slot.
3185
Georg Brandl3ee81df2008-05-17 18:14:43 +00003186- When printing an unraisable error, don't print exceptions. before
3187 the name. This duplicates the behavior whening normally printing
3188 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00003189

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00003690- Added a timeout parameter to the constructor of other protocols
3691 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3692 work started with create_connection() and timeout in httplib, and
3693 closes patch #723312.
3694
Vinay Sajip8549ce32007-05-06 17:53:37 +00003695- Patch #1676823: Added create_connection() to socket.py, which may be
3696 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00003697 and HTTPSConnection now accept an optional timeout).

Georg Brandl3ee81df2008-05-17 18:14:43 +00003721 AttributeError instead of an IOError when the server's response
3722 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003723
Georg Brandl3ee81df2008-05-17 18:14:43 +00003724- Patch #957650: "%var%" environment variable references are now

Georg Brandl3ee81df2008-05-17 18:14:43 +00003728- Patch #1429539: pdb now correctly initializes the __main__ module
3729 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003730 correctly now.
3731

Georg Brandl3ee81df2008-05-17 18:14:43 +00003739- Patch #1530482: add pydoc.render_doc() which returns the

Georg Brandl9e6b4702007-03-13 18:15:41 +00003752- Patch #1581073: add a flag to textwrap that prevents the dropping of
3753 whitespace while wrapping.
3754
Georg Brandl92a6bae2007-03-13 17:43:32 +00003755- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003756 are set for invalid interpolation sequences that would lead to
3757 errors on reading back those values.

3800 returned string up to the first NUL character.
3801

3811
Georg Brandl3ee81df2008-05-17 18:14:43 +00003812- unittest now verifies more of its assumptions. In particular,
3813 TestCase and TestSuite subclasses (not instances) are no longer
3814 accepted in TestSuite.addTest(). This should cause no
3815 incompatibility since it never made sense with ordinary subclasses
3816 -- the failure just occurred later, with a more cumbersome
3817 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00003818

3827
Georg Brandl3ee81df2008-05-17 18:14:43 +00003828- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00004206 time so that opening a database previously created with the DB_DUP
4207 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4208 opens. Specifically: dictionary assignment to a DB object will
4209 replace all values for a given key when the database allows
4210 duplicate values. DB users should use DB.put(k, v) when they want
4211 to store duplicates; not DB[k] = v.

4218 characters with ASCII value less than 32. Also, it correctly quotes
4219 dots only if they occur on a single line, as opposed to the previous
4220 behavior of quoting dots if they are the second character of any
4221 line.
