Georg Brandld2094602008-12-05 08:51:30 +00001003 method on file objects with closefd=False. The file descriptor is still

1378What's New in Python 2.6.1
1379==========================
1380
1381*Release date: 04-Dec-2008*
1382
1383Core and Builtins
1384-----------------
1385
1386- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1387 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1388 instead of throwing a MemoryError.
1389
1390- Issue #4367: Python would segfault during compiling when the unicodedata
1391 module couldn't be imported and \N escapes were present.
1392
1393- Issue #4348: Some bytearray methods returned that didn't cause any change to
1394 the bytearray, returned the same bytearray instead of a copy.
1395
1396- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1397
1398- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1399
1400- Issue #4048: The parser module now correctly validates relative imports.
1401
1402- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

1406 method does not return iterators for the 4th and 5th items.
1407
1408- Issue #4209: Enabling unicode_literals and the print_function in the same
1409 __future__ import didn't work.
1410
1411- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1412 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1413 really executed because I cannot move to such directory on win2k)
1414
1415- Issue #4069: When set.remove(element) is used with a set element, the element
1416 is temporarily replaced with an equivalent frozenset. But the eventual
1417 KeyError would always report the empty frozenset([]) as the missing key. Now
1418 it correctly refers to the initial element.
1419
1420- Fixed C99 style comments in several files. Python is now C89 compatible
1421 again.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001570- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1571 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1572 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1573 ``printf`` function, whereas PyString_FromFormat has an independent

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001591- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001592 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001593 was correctly parsed but parsing of subsequent arguments failed.
1594
Vinay Sajip35e3b032008-09-01 14:33:59 +00001595- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001596 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1597 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1598 when given a tuple of classes as second argument, were looking up
1599 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1600 type object.
1601
Neal Norwitz18aa3882008-08-24 05:04:52 +00001602- Fix crashes on memory allocation failure found with failmalloc.

1618
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001619- Issue #1204: The configure script now tests for additional libraries
1620 that may be required when linking against readline. This fixes issues
1621 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

1671 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1672 for catch_warnings() also led to an improvement in the raising of a

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001695- Issue #2975: When compiling several extension modules with Visual Studio 2008
1696 from the same python interpreter, some environment variables would grow
1697 without limit.
1698
Benjamin Peterson37346b22008-08-23 20:27:43 +00001699- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001736What's New in Python 2.6 beta 3?
1737================================
1738
Barry Warsaw07a4a382008-08-21 01:15:08 +00001739*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001740
1741Core and Builtins
1742-----------------
1743
Guido van Rossumf8402962008-08-20 15:01:50 +00001744- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1745 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1746 extensions do not automatically benefit from the class attribute
1747 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1748 to their tp_flags field if they care. This is a backwards
1749 compatibility feature; in 3.0, all types will use the cache by
1750 default.
1751
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001752- Keyword arguments can now follow starred arguments. (``f(a, *args,
1753 keyword=23)`` is now valid syntax.)
1754
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001755- ctypes function pointers that are COM methods have a boolean True
1756 value again.
1757
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001758- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1759 by denying s# to parse objects that have a releasebuffer procedure,
1760 and introducing s*.
1761
Georg Brandl1e13ea92008-08-11 09:07:59 +00001762- Issue #3537: Fix an assertion failure when an empty but presized dict
1763 object was stored in the freelist.
1764
Mark Dickinsonb6467572008-08-04 21:30:09 +00001765- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1766 ValueError consistently across platforms.
1767
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001768- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1769 (64bit Unix, for example), unichr() would truncate its argument and return
1770 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1771
Neal Norwitze7d8be82008-07-31 17:17:14 +00001772- Apply security patches from Apple.
1773
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001774- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1775 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1776
Antoine Pitrou92f82162008-07-25 22:22:08 +00001777- Issue #1819: function calls with several named parameters are now on
1778 average 35% faster (as measured by pybench).
1779
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001780- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1781 the python debugger steps into a class statement: the free variables (local
1782 variables defined in an outer scope) would be deleted from the outer scope.
1783
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001784- Issue #2620: Overflow checking when allocating or reallocating memory
1785 was not always being done properly in some python types and extension
1786 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1787 all been updated to perform better checks and places in the code that
1788 would previously leak memory on the error path when such an allocation
1789 failed have been fixed.

1793
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001794- Issue #3612: Added some missing basic types in ctypes.wintypes.
1795
Benjamin Petersone977ad42008-08-20 01:42:01 +00001796- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1797 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1798
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001799- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1800 version reported by these tools does not necessarily follow the python
1801 version numbering scheme, so the module is less strict when parsing it.
1802
Nick Coghlanf70385a2008-08-18 12:42:46 +00001803- Issue #2235: Added Py3k warnings for types which will become unhashable
1804 under the stricter __hash__ inheritance rules in 3.0. Several types
1805 which did not meet the rules for hash invariants and were already
1806 unhashable in 3.0 have now been explicitly flagged as unhashable in
1807 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1808 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1809
Brett Cannon88f801d2008-08-18 00:46:22 +00001810- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1811 imported into the module but exposed as part of the module's API.
1812
Brett Cannon7b96f072008-08-18 00:41:11 +00001813- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1814
Brett Cannon46225e72008-08-18 00:36:52 +00001815- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1816
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001817- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1818
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001819- Issue #3575: Incremental decoder's decode function now takes bytearray
1820 by using 's*' instead of 't#'.
1821
Jesus Cea585ad8a2009-07-02 15:37:21 +00001822- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001823 fails unicode conversion on 2nd parameter. (windows only)
1824
Facundo Batista94f243a2008-08-17 03:38:39 +00001825- Issue 2464. urllib2 now supports a malformation in the URL received
1826 in a redirect.
1827
Brett Cannonabe423e2008-08-16 21:47:07 +00001828- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001829 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001830
Facundo Batistaeb90b782008-08-16 14:44:07 +00001831- Issue #2776: fixed small issue when handling an URL with double slash
1832 after a 302 response in the case of not going through a proxy.
1833
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001834- Issue #2676: in the email package, content-type parsing was hanging on
1835 pathological input because of quadratic or exponential behaviour of a
1836 regular expression.
1837
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001838- Issue #3476: binary buffered reading through the new "io" library is now
1839 thread-safe.
1840
Brett Cannonbf3157b2008-08-14 05:00:03 +00001841- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1842 since mimetools itself is deprecated. Because modules are cached, all
1843 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1844
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001845- Issue #3134: shutil referenced undefined WindowsError symbol.
1846
Robert Schuppenies14646332008-08-10 11:01:53 +00001847- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1848 menu entries were not deleted.
1849
Brett Cannon83e81842008-08-09 23:30:55 +00001850- Copied the implementation of reduce() to _functools.reduce() to have a
1851 version that did not raise a DeprecationWarning under -3.
1852
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001853- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1854 a MemoryError rather than silently stop the iteration.
1855
Guido van Rossum59ce9012008-08-09 14:55:34 +00001856- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1857 to _sre.compile() will now be rejected. This should not affect anybody
1858 since the re.compile() function never generates invalid re-bytecode.
1859
Skip Montanaroa032bf42008-08-08 22:52:51 +00001860- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1861 upon first access it can be automatically initialized from the csv file if
1862 it wasn't initialized during instantiation.
1863
Brett Cannon3aa2a492008-08-06 22:28:09 +00001864- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1865 the reload() built-in has been removed.
1866
Brett Cannon7e30b672008-08-04 21:52:25 +00001867- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001868 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001879 asking for a specific length. This problem only affected files opened

1932
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001933*Release date: 17-Jul-2008*

1936-----------------
1937
Georg Brandl3e483f62008-07-16 22:57:41 +00001938- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1939 its methods now allow for items objects that can be converted to
1940 an integer using operator.index().
1941
Mark Dickinson64b7e502008-07-16 09:40:03 +00001942- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1943 produced a ValueError instead of giving the correct float.
1944
Eric Smitha5fa5a22008-07-16 00:11:49 +00001945- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1946 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1947
Mark Dickinson7103aa42008-07-15 19:08:33 +00001948- Issue #3008: the float type has a new instance method 'float.hex'
1949 and a new class method 'float.fromhex' to convert floating-point
1950 numbers to and from hexadecimal strings, respectively.
1951
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001952- Issue #2235: __hash__ is once again inherited by default. To allow
1953 collections.Hashable to remain meaningful in the presence of the
1954 default hash implementation (object.__hash__), it is now possible
1955 to explicit block inheritance of hash by setting __hash__=None at
1956 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1957 level.
1958
Nick Coghlanb028f502008-07-13 14:52:36 +00001959- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1960 the parent module cannot be found while performing an absolute import.
1961 This means that an incorrectly defined __package__ attribute will
1962 now only prevent relative imports in that module rather than causing
1963 all imports from that module to fail.
1964
Nick Coghlan14ff9942008-07-08 14:21:42 +00001965- Issue #2517: Allow unicode messages in Exceptions again by correctly

1975 another thread's dictionary.
1976
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001977- Issue #3004: Minor change to slice.indices(): the start and stop
1978 arguments are now treated identically, making the behaviour easier
1979 to describe and understand. For example, slice(None, -10,
1980 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1981 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1982 10, -1).
1983
Georg Brandl278fc502008-07-19 12:46:12 +00001984- Issue #3219: Calling a function with repeated keyword arguments,
1985 f(a=2, a=23), would not cause a syntax error. This was a regression
1986 from 2.4 caused by the switch to the new compiler.

1989 other freelists. Changes their CompactFreeList apis into

1997 error when they failed.
1998
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001999- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002024- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2025 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002026 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002027 content-length. The problem had been corrected in the 2.4 branch, but never
2028 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002043- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

2453
Georg Brandl74a1dea2008-05-28 11:21:39 +00002454- Add ``PyType_Modified()`` as a public API to clear the type cache.
2455
2456- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00002457
2458- The PyString functions have been renamed to PyBytes. A batch of
2459 defines were added so that the linker still sees the original
2460 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002498- Issue #1631171: Re-implement the 'warnings' module in C (the
2499 original Python code has been kept as backup). This will allow for
2500 using the 'warning's machinery in such places as the parser where
2501 use of pure Python code is not possible. Both the ``showarning()``
2502 and ``formatwarning()`` gain an optional 'line' argument which is
2503 not called by default for backwards-compatibility reasons. Setting
2504 ``warnings.showwarning()`` to an implementation that lacks support
2505 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002547- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002548 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002568- Issue #2550: The approach used by client/server code for obtaining
2569 ports to listen on in network-oriented tests has been refined in an
2570 effort to facilitate running multiple instances of the entire
2571 regression test suite in parallel without issue.
2572 test_support.bind_port() has been fixed such that it will always
2573 return a unique port -- which wasn't always the case with the
2574 previous implementation, especially if socket options had been set
2575 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2576 new implementation of bind_port() will actually raise an exception
2577 if it is passed an AF_INET/SOCK_STREAM socket with either the
2578 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2579 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2580 the socket it's been passed. This currently only applies to
2581 Windows. This option prevents any other sockets from binding to the
2582 host/port we've bound to, thus removing the possibility of the
2583 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2584 when a second SOCK_STREAM socket binds and accepts to a host/port
2585 that's already been bound by another socket. The optional preferred
2586 port parameter to bind_port() has been removed. Under no
2587 circumstances should tests be hard coding ports!
2588
2589 test_support.find_unused_port() has also been introduced, which will
2590 pass a temporary socket object to bind_port() in order to obtain an
2591 unused port. The temporary socket object is then closed and
2592 deleted, and the port is returned. This method should only be used
2593 for obtaining an unused port in order to pass to an external program
2594 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2595 a parameter to a server-oriented class that doesn't give you direct
2596 access to the underlying socket used.
2597
2598 Finally, test_support.HOST has been introduced, which should be used
2599 for the host argument of any relevant socket calls (i.e. bind and
2600 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002601
2602 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002603 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002604 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2605 test_asynchat and test_socket_ssl.
2606
Georg Brandl3ee81df2008-05-17 18:14:43 +00002607 It is now possible for multiple instances of the regression test
2608 suite to run in parallel without issue.

2875-----------------
2876
Fred Drakea8ee94b2008-03-01 02:45:07 +00002877- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002878 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002879
Georg Brandlad61bc82008-02-23 15:11:18 +00002880- Issue #2067: file.__exit__() now calls subclasses' close() method.
2881
2882- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002883
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002884- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002885 issue 215555 for a discussion.
2886
Eric Smitha73fbe72008-02-23 03:09:44 +00002887- Added the future_builtins module, which contains hex() and oct().
2888 These are the PEP 3127 version of these functions, designed to be
2889 compatible with the hex() and oct() builtins from Python 3.0. They
2890 differ slightly in their output formats from the existing, unchanged
2891 Python 2.6 builtins. The expected usage of the future_builtins
2892 module is:
2893 from future_builtins import hex, oct
2894
Eric Smith7ef40bf2008-02-20 23:34:22 +00002895- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2896 exponents for exponents with absolute value < 100. Follows C99
2897 standard. This is a change on Windows, which would use 3 digits.
2898 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2899 so that any alterations it does to the resulting string will be
2900 available in stringlib/formatter.h (for float.__format__).
2901
Eric Smith5a3c1352008-02-19 13:21:56 +00002902- Implemented PEP 3101, Advanced String Formatting. This adds a new
2903 builtin format(); a format() method for str and unicode; a
2904 __format__() method to object, str, unicode, int, long, float, and
2905 datetime; the class string.Formatter; and the C API
2906 PyObject_Format().
2907
Georg Brandl3ee81df2008-05-17 18:14:43 +00002908- Fixed several potential crashes, all caused by specially crafted
2909 __del__ methods exploiting objects in temporarily inconsistent
2910 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002911
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002912- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002913 prevent a possible crash: an Abstract Base Class would try to access
2914 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002915

Georg Brandl3ee81df2008-05-17 18:14:43 +00002919- Clear all free lists during a gc.collect() of the highest generation
2920 in order to allow pymalloc to free more arenas. Python may give back
2921 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002922
Georg Brandl3ee81df2008-05-17 18:14:43 +00002923- Issue #2045: Fix an infinite recursion triggered when printing a
2924 subclass of collections.defaultdict, if its default_factory is set
2925 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002926
Christian Heimesf75dbef2008-02-08 00:11:31 +00002927- Fixed a minor memory leak in dictobject.c. The content of the free
2928 list was not freed on interpreter shutdown.
2929
Georg Brandl5a7eca12010-03-21 19:29:04 +00002930- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00002931 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002932
Georg Brandl3ee81df2008-05-17 18:14:43 +00002933- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2934 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002935 to compact the internal free lists of pre-allocted ints and floats.
2936
Georg Brandl3ee81df2008-05-17 18:14:43 +00002937- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2938 calls. Python expected the return type int but the fork familie
2939 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002940
Georg Brandl3ee81df2008-05-17 18:14:43 +00002941- Issue #1678380: Fix a bug that identifies 0j and -0j when they

2951 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002952
Georg Brandl3ee81df2008-05-17 18:14:43 +00002953- Patch #1473257: generator objects gain a gi_code attribute. This is
2954 the same object as the func_code attribute of the function that
2955 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002956
Georg Brandl3ee81df2008-05-17 18:14:43 +00002957- Issue #1920: "while 0" statements were completely removed by the
2958 compiler, even in the presence of an "else" clause, which is

2960 correctly emits bytecode for the "else" suite.

Guido van Rossumeead05f2008-01-24 18:21:02 +00002962- A few crashers fixed: weakref_in_del.py (issue #1377858);
2963 loosing_dict_ref.py (issue #1303614, test67.py);
2964 borrowed_ref_[34].py (not in tracker).
2965
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002966- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002967 suppressed while an extension is loaded by calling SetErrorMode in
2968 dynload_win.c. The error is still reported properly.
2969
Georg Brandl3ee81df2008-05-17 18:14:43 +00002970- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002971 several extension methods and modules do not work without unicode
2972 support.
2973
Georg Brandl26543b12008-01-21 18:36:51 +00002974- Issue #1882: when compiling code from a string, encoding cookies in the
2975 second line of code were not always recognized correctly.
2976
Georg Brandl14404b62008-01-19 19:27:05 +00002977- Issue #1679: "0x" was taken as a valid integer literal.
2978
Georg Brandl6caad7d2008-01-26 14:19:22 +00002979- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002980 added.
2981
Christian Heimesc94e2b52008-01-14 04:13:37 +00002982- sys.float_info / PyFloat_GetInfo: The floating point information
2983 object was converted from a dict to a specialized structseq object.
2984
Georg Brandl3ee81df2008-05-17 18:14:43 +00002985- Patch #1816: Added sys.flags structseq. It exposes the status of
2986 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002987
Georg Brandl3ee81df2008-05-17 18:14:43 +00002988- Objects/structseq.c: Implemented new structseq representation. The
2989 patch makes structseqs (e.g. the return value of os.stat) more
2990 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002991
Georg Brandl3ee81df2008-05-17 18:14:43 +00002992- Patch #1700288: added a type attribute cache that caches method
2993 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002994
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002995- Bug #1776: __import__() no longer accepts filenames on any platform.
2996 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002997
Georg Brandlaed6c662008-01-07 17:25:53 +00002998- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2999
Georg Brandl3ee81df2008-05-17 18:14:43 +00003000- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3001 envvar and sys.dont_write_bytecode attribute. All these can be set
3002 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003003
Georg Brandl3ee81df2008-05-17 18:14:43 +00003004- Improve some exception messages when Windows fails to load an
3005 extension module. Now we get for example '%1 is not a valid Win32
3006 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003007
Georg Brandl3ee81df2008-05-17 18:14:43 +00003008- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003010- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3011 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003012
Christian Heimes0a8143f2007-12-18 23:22:54 +00003013- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003014 and INF. float("nan"), float("inf") and float("-inf") now work on
3015 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003016
Georg Brandl3ee81df2008-05-17 18:14:43 +00003017- Compiler now generates simpler and faster code for dictionary
3018 literals. The oparg for BUILD_MAP now indicates an estimated
3019 dictionary size. There is a new opcode, STORE_MAP, for adding
3020 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003021
Georg Brandl3ee81df2008-05-17 18:14:43 +00003022- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003049- Patch #1739468: Directories and zipfiles containing a __main__.py
3050 file can now be directly executed by passing their name to the
3051 interpreter. The directory/zipfile is automatically inserted as the
3052 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003053
Georg Brandl3ee81df2008-05-17 18:14:43 +00003054- Issue #1265: Fix a problem with sys.settrace, if the tracing
3055 function uses a generator expression when at the same time the
3056 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003057
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003058- sets and frozensets now have an isdisjoint() method.
3059
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003060- optimize the performance of builtin.sum().
3061
Neal Norwitz44f326e2007-10-05 05:29:17 +00003062- Fix warnings found by the new version of the Coverity checker.
3063
Georg Brandl5a7eca12010-03-21 19:29:04 +00003064- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003065 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3066 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003067
Georg Brandl3ee81df2008-05-17 18:14:43 +00003068- Issue #1686386: Tuple's tp_repr did not take into account the
3069 possibility of having a self-referential tuple, which is possible
3070 from C code. Nor did object's tp_str consider that a type's tp_str
3071 could do something that could lead to an inifinite recursion.
3072 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3073 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003074
Georg Brandl3ee81df2008-05-17 18:14:43 +00003075- Issue #1164: It was possible to trigger deadlock when using the
3076 'print' statement to write to a file since the GIL was not released
3077 as needed. Now PyObject_Print() does the right thing along with
3078 various tp_print implementations of the built-in types and those in
3079 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003080
Georg Brandl3ee81df2008-05-17 18:14:43 +00003081- Issue #1147: Exceptions were directly allowing string exceptions in
3082 their throw() method even though string exceptions no longer
3083 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003084
Georg Brandl3ee81df2008-05-17 18:14:43 +00003085- Issue #1096: Prevent a segfault from getting the repr of a very
3086 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003087
Brett Cannon1e534b52007-09-07 04:18:30 +00003088- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003089 PyObject_Call() never calling back out to Python code to trigger
3090 recursion depth updates/checks. Required the creation of a static
3091 RuntimeError instance in case normalizing an exception put the
3092 recursion check value past its limit. Fixes crashers
3093 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003094
Georg Brandl3ee81df2008-05-17 18:14:43 +00003095- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003108- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003109 __*__ attributes. (Some already existed, e.g., __doc__ and
3110 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003111
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003112- Add -3 option to the interpreter to warn about features that are
3113 deprecated and will be changed/removed in Python 3.0.
3114
Georg Brandl2134e752007-05-21 20:34:16 +00003115- Patch #1686487: you can now pass any mapping after '**' in function
3116 calls.
3117
Collin Winter62903052007-05-18 23:11:24 +00003118- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003119 "except E as target:". This is to provide forwards compatibility
3120 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003121
Brett Cannon229cee22007-05-05 01:34:02 +00003122- Deprecate BaseException.message as per PEP 352.
3123
Georg Brandl3ee81df2008-05-17 18:14:43 +00003124- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003125 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003126
Vinay Sajip8549ce32007-05-06 17:53:37 +00003127- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003128 setting a plain string, ie don't expand to single letter identifiers.
3129
Raymond Hettinger13936692007-04-11 18:40:58 +00003130- Request #1191699: Slices can now be pickled.
3131
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003132- Request #1193128: str.translate() now allows a None argument for
3133 translations that only remove characters without re-mapping the
3134 remaining characters.
3135
Georg Brandl5cb76c12007-03-21 09:00:39 +00003136- Patch #1682205: a TypeError while unpacking an iterable is no longer
3137 masked by a generic one with the message "unpack non-sequence".
3138
Neal Norwitzaa754b72007-03-21 06:39:48 +00003139- Remove unused file Python/fmod.c.
3140
Guido van Rossum143b5642007-03-23 04:58:42 +00003141- Bug #1683368: The object.__init__() and object.__new__() methods are
3142 now stricter in rejecting excess arguments. The only time when
3143 either allows excess arguments is when it is not overridden and the
3144 other one is. For backwards compatibility, when both are
3145 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003146 warning later). Also, type.__init__() insists on the same signature
3147 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003148
Georg Brandl3ee81df2008-05-17 18:14:43 +00003149- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3150 object to complex using its __complex__() method before falling back
3151 to the __float__() method. Therefore, the functions in the cmath
3152 module now can operate on objects that define a __complex__()
3153 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003154
Georg Brandl3ee81df2008-05-17 18:14:43 +00003155- Patch #1623563: allow __class__ assignment for classes with
3156 __slots__. The old and the new class are still required to have the
3157 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003158
Georg Brandl3ee81df2008-05-17 18:14:43 +00003159- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00003162- Patch #1462488: Python no longer segfaults when
3163 ``object.__reduce_ex__()`` is called with an object that is faking
3164 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003165
Georg Brandl3ee81df2008-05-17 18:14:43 +00003166- Patch #1680015: Don't modify __slots__ tuple if it contains an

3170
Georg Brandl7b9c5552007-03-12 14:30:05 +00003171- Bug #1678647: write a newline after printing an exception in any
3172 case, even when converting the value to a string failed.
3173
Georg Brandl871f1bc2007-03-12 13:17:36 +00003174- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003175 its argument, if it exists. If not, it will work like before. This
3176 allows customizing the output of dir() in the presence of a
3177 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003178
Collin Winter276887b2007-03-12 16:11:39 +00003179- Patch #922167: Python no longer segfaults when faced with infinitely
3180 self-recursive reload() calls (as reported by bug #742342).
3181
Georg Brandl3ee81df2008-05-17 18:14:43 +00003182- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00003185- Patch #1491866: change the complex() constructor to allow
3186 parthensized forms. This means complex(repr(x)) now works instead of
3187 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003188
Georg Brandlaa2321b2007-03-07 00:40:28 +00003189- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003190 makes the filenames the warning module prints much more sensible
3191 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003192
Georg Brandl49aafc92007-03-07 00:34:46 +00003193- Variant of patch #697613: don't exit the interpreter on a SystemExit
3194 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003195 variable is given, but break into the interactive interpreter just
3196 like on other exceptions or normal program exit.
Georg Brandl49aafc92007-03-07 00:34:46 +00003197

3699
Facundo Batistad918a652007-04-24 13:54:38 +00003700- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003701 the client's request was successfully received, understood, and
3702 accepted. Now in these cases no error is raised in urllib (issue
3703 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00003704

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00003711- Added a timeout parameter to the constructor of other protocols
3712 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3713 work started with create_connection() and timeout in httplib, and
3714 closes patch #723312.
3715
Vinay Sajip8549ce32007-05-06 17:53:37 +00003716- Patch #1676823: Added create_connection() to socket.py, which may be
3717 called with a timeout, and use it from httplib (whose HTTPConnection

Facundo Batista07c78be2007-03-23 18:54:07 +00003719
Martin v. Löwis0af33882007-03-23 13:27:15 +00003720- Bug #978833: Revert r50844, as it broke _socketobject.dup.

3740
Georg Brandlf66b6032007-03-14 08:27:52 +00003741- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00003742 AttributeError instead of an IOError when the server's response
3743 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003744
Georg Brandl3ee81df2008-05-17 18:14:43 +00003745- Patch #957650: "%var%" environment variable references are now
3746 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl3ee81df2008-05-17 18:14:43 +00003749- Patch #1429539: pdb now correctly initializes the __main__ module
3750 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003751 correctly now.
3752
Georg Brandlbad6f192007-03-13 21:32:56 +00003753- The nonobvious commands.getstatus() function is now deprecated.

3759
Georg Brandl3ee81df2008-05-17 18:14:43 +00003760- Patch #1530482: add pydoc.render_doc() which returns the
3761 documentation for a thing instead of paging it to stdout, which
3762 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00003763
Georg Brandl3ee81df2008-05-17 18:14:43 +00003764- Patch #1533909: the timeit module now accepts callables in addition

Georg Brandl9e6b4702007-03-13 18:15:41 +00003773- Patch #1581073: add a flag to textwrap that prevents the dropping of

3775
Georg Brandl92a6bae2007-03-13 17:43:32 +00003776- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003777 are set for invalid interpolation sequences that would lead to
3778 errors on reading back those values.

3795 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00003813

3821 returned string up to the first NUL character.
3822

3832
Georg Brandl3ee81df2008-05-17 18:14:43 +00003833- unittest now verifies more of its assumptions. In particular,
3834 TestCase and TestSuite subclasses (not instances) are no longer
3835 accepted in TestSuite.addTest(). This should cause no
3836 incompatibility since it never made sense with ordinary subclasses
3837 -- the failure just occurred later, with a more cumbersome
3838 exception.

3847 given a unicode argument and os.listdir() returns unicode filenames.
3848
Georg Brandl3ee81df2008-05-17 18:14:43 +00003849- Patch #1673619: setup.py identifies extension modules it doesn't
3850 know how to build and those it knows how to build but that fail to
3851 build.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004226- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00004227 time so that opening a database previously created with the DB_DUP
4228 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4229 opens. Specifically: dictionary assignment to a DB object will
4230 replace all values for a given key when the database allows
4231 duplicate values. DB users should use DB.put(k, v) when they want
4232 to store duplicates; not DB[k] = v.

4239 characters with ASCII value less than 32. Also, it correctly quotes
4240 dots only if they occur on a single line, as opposed to the previous
4241 behavior of quoting dots if they are the second character of any
4242 line.
