1347*Release date: 04-Dec-2008*
1348
1349Core and Builtins
1350-----------------
1351
1352- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1353 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1354 instead of throwing a MemoryError.
1355
1356- Issue #4367: Python would segfault during compiling when the unicodedata
1357 module couldn't be imported and \N escapes were present.
1358
1359- Issue #4348: Some bytearray methods returned that didn't cause any change to
1360 the bytearray, returned the same bytearray instead of a copy.
1361
1362- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1363
1364- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1365
1366- Issue #4048: The parser module now correctly validates relative imports.
1367
1368- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

1375 __future__ import didn't work.
1376
1377- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1378 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1379 really executed because I cannot move to such directory on win2k)
1380
1381- Issue #4069: When set.remove(element) is used with a set element, the element
1382 is temporarily replaced with an equivalent frozenset. But the eventual
1383 KeyError would always report the empty frozenset([]) as the missing key. Now
1384 it correctly refers to the initial element.
1385

1387 again.

1535
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001536- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1537 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1538 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1539 ``printf`` function, whereas PyString_FromFormat has an independent
1540 implementation and uses "%zd" on all platforms for size_t values.
1541 This makes a difference on win64, where ``printf`` needs "%Id" to display
1542 64bit values.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001702What's New in Python 2.6 beta 3?
1703================================
1704
Barry Warsaw07a4a382008-08-21 01:15:08 +00001705*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001706
1707Core and Builtins
1708-----------------
1709
Guido van Rossumf8402962008-08-20 15:01:50 +00001710- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1711 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1712 extensions do not automatically benefit from the class attribute
1713 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1714 to their tp_flags field if they care. This is a backwards
1715 compatibility feature; in 3.0, all types will use the cache by
1716 default.
1717
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001718- Keyword arguments can now follow starred arguments. (``f(a, *args,
1719 keyword=23)`` is now valid syntax.)
1720
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001721- ctypes function pointers that are COM methods have a boolean True
1722 value again.
1723
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001724- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1725 by denying s# to parse objects that have a releasebuffer procedure,
1726 and introducing s*.
1727
Georg Brandl1e13ea92008-08-11 09:07:59 +00001728- Issue #3537: Fix an assertion failure when an empty but presized dict
1729 object was stored in the freelist.
1730
Mark Dickinsonb6467572008-08-04 21:30:09 +00001731- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1732 ValueError consistently across platforms.
1733
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001734- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1735 (64bit Unix, for example), unichr() would truncate its argument and return
1736 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1737
Neal Norwitze7d8be82008-07-31 17:17:14 +00001738- Apply security patches from Apple.
1739
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001740- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1741 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1742
Antoine Pitrou92f82162008-07-25 22:22:08 +00001743- Issue #1819: function calls with several named parameters are now on
1744 average 35% faster (as measured by pybench).
1745
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001746- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1747 the python debugger steps into a class statement: the free variables (local
1748 variables defined in an outer scope) would be deleted from the outer scope.
1749
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001750- Issue #2620: Overflow checking when allocating or reallocating memory
1751 was not always being done properly in some python types and extension
1752 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1753 all been updated to perform better checks and places in the code that
1754 would previously leak memory on the error path when such an allocation
1755 failed have been fixed.

1759
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001760- Issue #3612: Added some missing basic types in ctypes.wintypes.
1761
Benjamin Petersone977ad42008-08-20 01:42:01 +00001762- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1763 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1764
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001765- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1766 version reported by these tools does not necessarily follow the python
1767 version numbering scheme, so the module is less strict when parsing it.
1768
Nick Coghlanf70385a2008-08-18 12:42:46 +00001769- Issue #2235: Added Py3k warnings for types which will become unhashable
1770 under the stricter __hash__ inheritance rules in 3.0. Several types
1771 which did not meet the rules for hash invariants and were already
1772 unhashable in 3.0 have now been explicitly flagged as unhashable in
1773 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1774 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1775
Brett Cannon88f801d2008-08-18 00:46:22 +00001776- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1777 imported into the module but exposed as part of the module's API.
1778
Brett Cannon7b96f072008-08-18 00:41:11 +00001779- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1780
Brett Cannon46225e72008-08-18 00:36:52 +00001781- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001783- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1784
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001785- Issue #3575: Incremental decoder's decode function now takes bytearray
1786 by using 's*' instead of 't#'.
1787
Jesus Cea585ad8a2009-07-02 15:37:21 +00001788- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001789 fails unicode conversion on 2nd parameter. (windows only)
1790
Facundo Batista94f243a2008-08-17 03:38:39 +00001791- Issue 2464. urllib2 now supports a malformation in the URL received
1792 in a redirect.
1793
Brett Cannonabe423e2008-08-16 21:47:07 +00001794- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001795 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001796
Facundo Batistaeb90b782008-08-16 14:44:07 +00001797- Issue #2776: fixed small issue when handling an URL with double slash
1798 after a 302 response in the case of not going through a proxy.
1799
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001800- Issue #2676: in the email package, content-type parsing was hanging on
1801 pathological input because of quadratic or exponential behaviour of a
1802 regular expression.
1803
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001804- Issue #3476: binary buffered reading through the new "io" library is now
1805 thread-safe.
1806
Brett Cannonbf3157b2008-08-14 05:00:03 +00001807- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1808 since mimetools itself is deprecated. Because modules are cached, all
1809 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1810
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001811- Issue #3134: shutil referenced undefined WindowsError symbol.
1812
Robert Schuppenies14646332008-08-10 11:01:53 +00001813- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1814 menu entries were not deleted.
1815
Brett Cannon83e81842008-08-09 23:30:55 +00001816- Copied the implementation of reduce() to _functools.reduce() to have a
1817 version that did not raise a DeprecationWarning under -3.
1818
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001819- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1820 a MemoryError rather than silently stop the iteration.
1821
Guido van Rossum59ce9012008-08-09 14:55:34 +00001822- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1823 to _sre.compile() will now be rejected. This should not affect anybody
1824 since the re.compile() function never generates invalid re-bytecode.
1825
Skip Montanaroa032bf42008-08-08 22:52:51 +00001826- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1827 upon first access it can be automatically initialized from the csv file if
1828 it wasn't initialized during instantiation.
1829
Brett Cannon3aa2a492008-08-06 22:28:09 +00001830- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1831 the reload() built-in has been removed.
1832
Brett Cannon7e30b672008-08-04 21:52:25 +00001833- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001834 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001845 asking for a specific length. This problem only affected files opened
1846 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001847

1872 file name rather than a ZipInfo instance, so files are extracted with
1873 mode 0600 rather than 000 under Unix.
1874
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001875- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1876 argument in python 2.5, this broke code that subclassed Popen to include its

1888 interaction with the tp_hash slot (added in 2.6b2) are now documented
1889
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001890- Issue #643841: The language reference now provides more detailed
1891 coverage of the lookup process for special methods. The disclaimers
1892 regarding lack of coverage of new-style classes have also been
1893 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001896What's New in Python 2.6 beta 2?
1897================================
1898
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001899*Release date: 17-Jul-2008*
1900
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001901Core and Builtins
1902-----------------
1903
Georg Brandl3e483f62008-07-16 22:57:41 +00001904- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1905 its methods now allow for items objects that can be converted to
1906 an integer using operator.index().
1907
Mark Dickinson64b7e502008-07-16 09:40:03 +00001908- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1909 produced a ValueError instead of giving the correct float.
1910
Eric Smitha5fa5a22008-07-16 00:11:49 +00001911- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1912 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1913
Mark Dickinson7103aa42008-07-15 19:08:33 +00001914- Issue #3008: the float type has a new instance method 'float.hex'
1915 and a new class method 'float.fromhex' to convert floating-point
1916 numbers to and from hexadecimal strings, respectively.
1917
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001918- Issue #2235: __hash__ is once again inherited by default. To allow
1919 collections.Hashable to remain meaningful in the presence of the
1920 default hash implementation (object.__hash__), it is now possible
1921 to explicit block inheritance of hash by setting __hash__=None at
1922 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1923 level.
1924
Nick Coghlanb028f502008-07-13 14:52:36 +00001925- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1926 the parent module cannot be found while performing an absolute import.
1927 This means that an incorrectly defined __package__ attribute will
1928 now only prevent relative imports in that module rather than causing
1929 all imports from that module to fail.
1930
Nick Coghlan14ff9942008-07-08 14:21:42 +00001931- Issue #2517: Allow unicode messages in Exceptions again by correctly
1932 bypassing the instance dictionary when looking up __unicode__ on
1933 new-style classes.
1934
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001935- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1936 set to a custom object whose write() method happens to install
1937 another file in sys.stdout.
1938
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001939- Issue #3088: Corrected a race condition in classes derived from
1940 threading.local: the first member set by a thread could be saved in
1941 another thread's dictionary.
1942
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001943- Issue #3004: Minor change to slice.indices(): the start and stop
1944 arguments are now treated identically, making the behaviour easier
1945 to describe and understand. For example, slice(None, -10,
1946 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1947 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1948 10, -1).
1949
Georg Brandl278fc502008-07-19 12:46:12 +00001950- Issue #3219: Calling a function with repeated keyword arguments,
1951 f(a=2, a=23), would not cause a syntax error. This was a regression
1952 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001953
Georg Brandl278fc502008-07-19 12:46:12 +00001954- Issue #2862: Make int and float freelist management consistent with
1955 other freelists. Changes their CompactFreeList apis into
1956 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001957

1959-------
1960
Thomas Heller57adf222008-08-14 19:10:48 +00001961- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1962 api functions without holding the GIL, which could lead to a fatal
1963 error when they failed.
1964
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001965- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00001973- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1974 ForkingPickler.register() to resolve conflict with ctypes.
1975
Vinay Sajip51e65192008-07-18 09:01:10 +00001976- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001977
Thomas Heller880f5292008-07-15 19:39:38 +00001978- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1979 a valid dlerror() message.
1980
Thomas Heller2bad6572008-07-15 17:19:50 +00001981- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1982 incomplete structure was created.

1987
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001988- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001989
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001990- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1991 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001992 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001993 content-length. The problem had been corrected in the 2.4 branch, but never
1994 merged into trunk.
1995
Georg Brandle78fbcc2008-07-05 10:13:36 +00001996- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002007 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00002008
Nick Coghlanc060b0e2008-07-02 13:09:19 +00002009- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2010 handling is now the same as that of other special attributes like __name__).
2011
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002012- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
2013 removal in Python 3.0 in favor of urllib2.urlopen().

2465 original Python code has been kept as backup). This will allow for
2466 using the 'warning's machinery in such places as the parser where
2467 use of pure Python code is not possible. Both the ``showarning()``
2468 and ``formatwarning()`` gain an optional 'line' argument which is
2469 not called by default for backwards-compatibility reasons. Setting
2470 ``warnings.showwarning()`` to an implementation that lacks support
2471 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002534- Issue #2550: The approach used by client/server code for obtaining
2535 ports to listen on in network-oriented tests has been refined in an
2536 effort to facilitate running multiple instances of the entire
2537 regression test suite in parallel without issue.
2538 test_support.bind_port() has been fixed such that it will always
2539 return a unique port -- which wasn't always the case with the
2540 previous implementation, especially if socket options had been set
2541 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2542 new implementation of bind_port() will actually raise an exception
2543 if it is passed an AF_INET/SOCK_STREAM socket with either the
2544 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2545 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2546 the socket it's been passed. This currently only applies to
2547 Windows. This option prevents any other sockets from binding to the
2548 host/port we've bound to, thus removing the possibility of the
2549 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2550 when a second SOCK_STREAM socket binds and accepts to a host/port
2551 that's already been bound by another socket. The optional preferred
2552 port parameter to bind_port() has been removed. Under no
2553 circumstances should tests be hard coding ports!
2554
2555 test_support.find_unused_port() has also been introduced, which will
2556 pass a temporary socket object to bind_port() in order to obtain an
2557 unused port. The temporary socket object is then closed and
2558 deleted, and the port is returned. This method should only be used
2559 for obtaining an unused port in order to pass to an external program
2560 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2561 a parameter to a server-oriented class that doesn't give you direct
2562 access to the underlying socket used.
2563
2564 Finally, test_support.HOST has been introduced, which should be used
2565 for the host argument of any relevant socket calls (i.e. bind and
2566 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002567
2568 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002569 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002570 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2571 test_asynchat and test_socket_ssl.
2572
Georg Brandl3ee81df2008-05-17 18:14:43 +00002573 It is now possible for multiple instances of the regression test
2574 suite to run in parallel without issue.

2841-----------------
2842
Fred Drakea8ee94b2008-03-01 02:45:07 +00002843- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002844 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00002846- Issue #2067: file.__exit__() now calls subclasses' close() method.
2847
2848- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002849
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002850- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002851 issue 215555 for a discussion.
2852
Eric Smitha73fbe72008-02-23 03:09:44 +00002853- Added the future_builtins module, which contains hex() and oct().
2854 These are the PEP 3127 version of these functions, designed to be
2855 compatible with the hex() and oct() builtins from Python 3.0. They
2856 differ slightly in their output formats from the existing, unchanged
2857 Python 2.6 builtins. The expected usage of the future_builtins
2858 module is:
2859 from future_builtins import hex, oct
2860
Eric Smith7ef40bf2008-02-20 23:34:22 +00002861- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2862 exponents for exponents with absolute value < 100. Follows C99
2863 standard. This is a change on Windows, which would use 3 digits.
2864 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2865 so that any alterations it does to the resulting string will be
2866 available in stringlib/formatter.h (for float.__format__).
2867
Eric Smith5a3c1352008-02-19 13:21:56 +00002868- Implemented PEP 3101, Advanced String Formatting. This adds a new
2869 builtin format(); a format() method for str and unicode; a
2870 __format__() method to object, str, unicode, int, long, float, and
2871 datetime; the class string.Formatter; and the C API
2872 PyObject_Format().
2873
Georg Brandl3ee81df2008-05-17 18:14:43 +00002874- Fixed several potential crashes, all caused by specially crafted
2875 __del__ methods exploiting objects in temporarily inconsistent
2876 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002877
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002878- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002879 prevent a possible crash: an Abstract Base Class would try to access
2880 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002881

Georg Brandl3ee81df2008-05-17 18:14:43 +00002885- Clear all free lists during a gc.collect() of the highest generation
2886 in order to allow pymalloc to free more arenas. Python may give back
2887 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002888
Georg Brandl3ee81df2008-05-17 18:14:43 +00002889- Issue #2045: Fix an infinite recursion triggered when printing a
2890 subclass of collections.defaultdict, if its default_factory is set
2891 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002892
Christian Heimesf75dbef2008-02-08 00:11:31 +00002893- Fixed a minor memory leak in dictobject.c. The content of the free
2894 list was not freed on interpreter shutdown.
2895
Georg Brandl5a7eca12010-03-21 19:29:04 +00002896- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00002898
Georg Brandl3ee81df2008-05-17 18:14:43 +00002899- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2900 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002901 to compact the internal free lists of pre-allocted ints and floats.
2902
Georg Brandl3ee81df2008-05-17 18:14:43 +00002903- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2904 calls. Python expected the return type int but the fork familie
2905 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002906

2917 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002918
Georg Brandl3ee81df2008-05-17 18:14:43 +00002919- Patch #1473257: generator objects gain a gi_code attribute. This is
2920 the same object as the func_code attribute of the function that
2921 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002922
Georg Brandl3ee81df2008-05-17 18:14:43 +00002923- Issue #1920: "while 0" statements were completely removed by the
2924 compiler, even in the presence of an "else" clause, which is
2925 supposed to be run when the condition is false. Now the compiler
2926 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002927
Guido van Rossumeead05f2008-01-24 18:21:02 +00002928- A few crashers fixed: weakref_in_del.py (issue #1377858);
2929 loosing_dict_ref.py (issue #1303614, test67.py);
2930 borrowed_ref_[34].py (not in tracker).
2931
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002932- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002933 suppressed while an extension is loaded by calling SetErrorMode in

2935
Georg Brandl3ee81df2008-05-17 18:14:43 +00002936- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002937 several extension methods and modules do not work without unicode
2938 support.
2939
Georg Brandl26543b12008-01-21 18:36:51 +00002940- Issue #1882: when compiling code from a string, encoding cookies in the

2942
Georg Brandl14404b62008-01-19 19:27:05 +00002943- Issue #1679: "0x" was taken as a valid integer literal.
2944
Georg Brandl6caad7d2008-01-26 14:19:22 +00002945- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002946 added.
2947
Christian Heimesc94e2b52008-01-14 04:13:37 +00002948- sys.float_info / PyFloat_GetInfo: The floating point information
2949 object was converted from a dict to a specialized structseq object.
2950
Georg Brandl3ee81df2008-05-17 18:14:43 +00002951- Patch #1816: Added sys.flags structseq. It exposes the status of
2952 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002953
Georg Brandl3ee81df2008-05-17 18:14:43 +00002954- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00002958- Patch #1700288: added a type attribute cache that caches method
2959 accesses, resulting in speedups in heavily object-oriented code.

Georg Brandlaed6c662008-01-07 17:25:53 +00002964- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2965
Georg Brandl3ee81df2008-05-17 18:14:43 +00002966- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2967 envvar and sys.dont_write_bytecode attribute. All these can be set
2968 to forbid Python to attempt to write compiled bytecode files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002970- Improve some exception messages when Windows fails to load an
2971 extension module. Now we get for example '%1 is not a valid Win32
2972 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002980 and INF. float("nan"), float("inf") and float("-inf") now work on
2981 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002983- Compiler now generates simpler and faster code for dictionary
2984 literals. The oparg for BUILD_MAP now indicates an estimated
2985 dictionary size. There is a new opcode, STORE_MAP, for adding
2986 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003015- Patch #1739468: Directories and zipfiles containing a __main__.py
3016 file can now be directly executed by passing their name to the
3017 interpreter. The directory/zipfile is automatically inserted as the
3018 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003020- Issue #1265: Fix a problem with sys.settrace, if the tracing
3021 function uses a generator expression when at the same time the
3022 executed code is closing a paused generator.

3029
Georg Brandl5a7eca12010-03-21 19:29:04 +00003030- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003031 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3032 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003033
Georg Brandl3ee81df2008-05-17 18:14:43 +00003034- Issue #1686386: Tuple's tp_repr did not take into account the
3035 possibility of having a self-referential tuple, which is possible
3036 from C code. Nor did object's tp_str consider that a type's tp_str
3037 could do something that could lead to an inifinite recursion.
3038 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3039 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003040
Georg Brandl3ee81df2008-05-17 18:14:43 +00003041- Issue #1164: It was possible to trigger deadlock when using the
3042 'print' statement to write to a file since the GIL was not released
3043 as needed. Now PyObject_Print() does the right thing along with
3044 various tp_print implementations of the built-in types and those in
3045 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003046
Georg Brandl3ee81df2008-05-17 18:14:43 +00003047- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannona0c05512007-09-10 21:38:27 +00003053
Brett Cannon1e534b52007-09-07 04:18:30 +00003054- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003055 PyObject_Call() never calling back out to Python code to trigger
3056 recursion depth updates/checks. Required the creation of a static
3057 RuntimeError instance in case normalizing an exception put the
3058 recursion check value past its limit. Fixes crashers
3059 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00003074- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003075 __*__ attributes. (Some already existed, e.g., __doc__ and
3076 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003077
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003078- Add -3 option to the interpreter to warn about features that are

3080
Georg Brandl2134e752007-05-21 20:34:16 +00003081- Patch #1686487: you can now pass any mapping after '**' in function
3082 calls.
3083
Collin Winter62903052007-05-18 23:11:24 +00003084- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003085 "except E as target:". This is to provide forwards compatibility
3086 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00003093- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003094 setting a plain string, ie don't expand to single letter identifiers.
3095
Raymond Hettinger13936692007-04-11 18:40:58 +00003096- Request #1191699: Slices can now be pickled.
3097
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003098- Request #1193128: str.translate() now allows a None argument for
3099 translations that only remove characters without re-mapping the
3100 remaining characters.
3101
Georg Brandl5cb76c12007-03-21 09:00:39 +00003102- Patch #1682205: a TypeError while unpacking an iterable is no longer

3104
Neal Norwitzaa754b72007-03-21 06:39:48 +00003105- Remove unused file Python/fmod.c.
3106
Guido van Rossum143b5642007-03-23 04:58:42 +00003107- Bug #1683368: The object.__init__() and object.__new__() methods are
3108 now stricter in rejecting excess arguments. The only time when
3109 either allows excess arguments is when it is not overridden and the
3110 other one is. For backwards compatibility, when both are
3111 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003112 warning later). Also, type.__init__() insists on the same signature
3113 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003114
Georg Brandl3ee81df2008-05-17 18:14:43 +00003115- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3116 object to complex using its __complex__() method before falling back
3117 to the __float__() method. Therefore, the functions in the cmath
3118 module now can operate on objects that define a __complex__()
3119 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003120
Georg Brandl3ee81df2008-05-17 18:14:43 +00003121- Patch #1623563: allow __class__ assignment for classes with
3122 __slots__. The old and the new class are still required to have the
3123 same slot names.

3136
Georg Brandl7b9c5552007-03-12 14:30:05 +00003137- Bug #1678647: write a newline after printing an exception in any
3138 case, even when converting the value to a string failed.
3139
Georg Brandl871f1bc2007-03-12 13:17:36 +00003140- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003141 its argument, if it exists. If not, it will work like before. This
3142 allows customizing the output of dir() in the presence of a
3143 __getattr__().

3152 parthensized forms. This means complex(repr(x)) now works instead of
3153 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003154
Georg Brandlaa2321b2007-03-07 00:40:28 +00003155- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003156 makes the filenames the warning module prints much more sensible
3157 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003158

Georg Brandl0fca97a2007-03-05 22:28:08 +00003170- Patch #1674228: when assigning a slice (old-style), check for the
3171 sq_ass_slice instead of the sq_slice slot.
3172
Georg Brandl3ee81df2008-05-17 18:14:43 +00003173- When printing an unraisable error, don't print exceptions. before
3174 the name. This duplicates the behavior whening normally printing
3175 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003708 AttributeError instead of an IOError when the server's response
3709 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003710

Georg Brandl3ee81df2008-05-17 18:14:43 +00003715- Patch #1429539: pdb now correctly initializes the __main__ module
3716 for the debugged script, which means that imports from __main__ work

3725
Georg Brandl3ee81df2008-05-17 18:14:43 +00003726- Patch #1530482: add pydoc.render_doc() which returns the

3741
Georg Brandl92a6bae2007-03-13 17:43:32 +00003742- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003743 are set for invalid interpolation sequences that would lead to
3744 errors on reading back those values.

3785

3787 returned string up to the first NUL character.
3788

3798
Georg Brandl3ee81df2008-05-17 18:14:43 +00003799- unittest now verifies more of its assumptions. In particular,
3800 TestCase and TestSuite subclasses (not instances) are no longer
3801 accepted in TestSuite.addTest(). This should cause no
3802 incompatibility since it never made sense with ordinary subclasses
3803 -- the failure just occurred later, with a more cumbersome
3804 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004091 that the SMTP.starttls() caller no longer needs to call ehlo()

4175 complex, tuple, list, dict, set, and frozenset. Formerly, it would

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004192- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00004193 time so that opening a database previously created with the DB_DUP
4194 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4195 opens. Specifically: dictionary assignment to a DB object will
4196 replace all values for a given key when the database allows
4197 duplicate values. DB users should use DB.put(k, v) when they want
4198 to store duplicates; not DB[k] = v.

4205 characters with ASCII value less than 32. Also, it correctly quotes
4206 dots only if they occur on a single line, as opposed to the previous
4207 behavior of quoting dots if they are the second character of any
4208 line.

4554 of w# format code incorrectly truncated the length to an int, even
4555 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4556 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004586- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4587 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
