1330What's New in Python 2.6.1
1331==========================
1332
1333*Release date: 04-Dec-2008*
1334
1335Core and Builtins
1336-----------------
1337
1338- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1339 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1340 instead of throwing a MemoryError.
1341
1342- Issue #4367: Python would segfault during compiling when the unicodedata
1343 module couldn't be imported and \N escapes were present.
1344
1345- Issue #4348: Some bytearray methods returned that didn't cause any change to
1346 the bytearray, returned the same bytearray instead of a copy.
1347
1348- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1349
1350- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1351
1352- Issue #4048: The parser module now correctly validates relative imports.
1353
1354- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1355 exec statement.

1357- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1358 method does not return iterators for the 4th and 5th items.
1359
1360- Issue #4209: Enabling unicode_literals and the print_function in the same
1361 __future__ import didn't work.
1362
1363- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1364 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1365 really executed because I cannot move to such directory on win2k)
1366
1367- Issue #4069: When set.remove(element) is used with a set element, the element
1368 is temporarily replaced with an equivalent frozenset. But the eventual
1369 KeyError would always report the empty frozenset([]) as the missing key. Now
1370 it correctly refers to the initial element.
1371
1372- Fixed C99 style comments in several files. Python is now C89 compatible
1373 again.

1521
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001522- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1523 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1524 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1525 ``printf`` function, whereas PyString_FromFormat has an independent
1526 implementation and uses "%zd" on all platforms for size_t values.
1527 This makes a difference on win64, where ``printf`` needs "%Id" to display

Brett Cannon1eaf0742008-09-02 01:25:16 +00001622- Issue 3602: Moved test.test_support.catch_warning() to
1623 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1624 for catch_warnings() also led to an improvement in the raising of a
1625 DeprecationWarning related to warnings.warn_explicit().

1645-----------------
1646
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001647- Issue #2975: When compiling several extension modules with Visual Studio 2008
1648 from the same python interpreter, some environment variables would grow
1649 without limit.
1650
Benjamin Peterson37346b22008-08-23 20:27:43 +00001651- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001688What's New in Python 2.6 beta 3?
1689================================
1690
Barry Warsaw07a4a382008-08-21 01:15:08 +00001691*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001692
1693Core and Builtins
1694-----------------
1695
Guido van Rossumf8402962008-08-20 15:01:50 +00001696- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1697 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1698 extensions do not automatically benefit from the class attribute
1699 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1700 to their tp_flags field if they care. This is a backwards
1701 compatibility feature; in 3.0, all types will use the cache by
1702 default.
1703
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001704- Keyword arguments can now follow starred arguments. (``f(a, *args,
1705 keyword=23)`` is now valid syntax.)
1706
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001707- ctypes function pointers that are COM methods have a boolean True
1708 value again.
1709
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001710- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1711 by denying s# to parse objects that have a releasebuffer procedure,
1712 and introducing s*.
1713
Georg Brandl1e13ea92008-08-11 09:07:59 +00001714- Issue #3537: Fix an assertion failure when an empty but presized dict
1715 object was stored in the freelist.
1716
Mark Dickinsonb6467572008-08-04 21:30:09 +00001717- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1718 ValueError consistently across platforms.
1719
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001720- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1721 (64bit Unix, for example), unichr() would truncate its argument and return
1722 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1723
Neal Norwitze7d8be82008-07-31 17:17:14 +00001724- Apply security patches from Apple.
1725
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001726- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1727 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1728
Antoine Pitrou92f82162008-07-25 22:22:08 +00001729- Issue #1819: function calls with several named parameters are now on
1730 average 35% faster (as measured by pybench).
1731
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001732- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1733 the python debugger steps into a class statement: the free variables (local
1734 variables defined in an outer scope) would be deleted from the outer scope.
1735
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001736- Issue #2620: Overflow checking when allocating or reallocating memory
1737 was not always being done properly in some python types and extension
1738 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1739 all been updated to perform better checks and places in the code that
1740 would previously leak memory on the error path when such an allocation
1741 failed have been fixed.
1742
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001743Library
1744-------
1745
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001746- Issue #3612: Added some missing basic types in ctypes.wintypes.
1747
Benjamin Petersone977ad42008-08-20 01:42:01 +00001748- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1749 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1750
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001751- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1752 version reported by these tools does not necessarily follow the python
1753 version numbering scheme, so the module is less strict when parsing it.
1754
Nick Coghlanf70385a2008-08-18 12:42:46 +00001755- Issue #2235: Added Py3k warnings for types which will become unhashable
1756 under the stricter __hash__ inheritance rules in 3.0. Several types
1757 which did not meet the rules for hash invariants and were already
1758 unhashable in 3.0 have now been explicitly flagged as unhashable in
1759 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1760 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1761
Brett Cannon88f801d2008-08-18 00:46:22 +00001762- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1763 imported into the module but exposed as part of the module's API.
1764

1770
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001771- Issue #3575: Incremental decoder's decode function now takes bytearray
1772 by using 's*' instead of 't#'.
1773
Jesus Cea585ad8a2009-07-02 15:37:21 +00001774- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001775 fails unicode conversion on 2nd parameter. (windows only)
1776
Facundo Batista94f243a2008-08-17 03:38:39 +00001777- Issue 2464. urllib2 now supports a malformation in the URL received
1778 in a redirect.
1779
Brett Cannonabe423e2008-08-16 21:47:07 +00001780- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001781 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001782
Facundo Batistaeb90b782008-08-16 14:44:07 +00001783- Issue #2776: fixed small issue when handling an URL with double slash
1784 after a 302 response in the case of not going through a proxy.
1785
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001786- Issue #2676: in the email package, content-type parsing was hanging on
1787 pathological input because of quadratic or exponential behaviour of a
1788 regular expression.
1789
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001790- Issue #3476: binary buffered reading through the new "io" library is now
1791 thread-safe.
1792
Brett Cannonbf3157b2008-08-14 05:00:03 +00001793- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1794 since mimetools itself is deprecated. Because modules are cached, all
1795 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1796
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001797- Issue #3134: shutil referenced undefined WindowsError symbol.
1798
Robert Schuppenies14646332008-08-10 11:01:53 +00001799- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1800 menu entries were not deleted.
1801
Brett Cannon83e81842008-08-09 23:30:55 +00001802- Copied the implementation of reduce() to _functools.reduce() to have a
1803 version that did not raise a DeprecationWarning under -3.
1804
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001805- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1806 a MemoryError rather than silently stop the iteration.
1807
Guido van Rossum59ce9012008-08-09 14:55:34 +00001808- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1809 to _sre.compile() will now be rejected. This should not affect anybody
1810 since the re.compile() function never generates invalid re-bytecode.
1811
Skip Montanaroa032bf42008-08-08 22:52:51 +00001812- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Brett Cannon3aa2a492008-08-06 22:28:09 +00001816- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1817 the reload() built-in has been removed.
1818

Antoine Pitroude781a42008-08-09 12:43:23 +00001831 asking for a specific length. This problem only affected files opened
1832 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001833

1858 file name rather than a ZipInfo instance, so files are extracted with
1859 mode 0600 rather than 000 under Unix.
1860
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001861- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1862 argument in python 2.5, this broke code that subclassed Popen to include its

1883================================
1884
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001885*Release date: 17-Jul-2008*
1886
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001887Core and Builtins
1888-----------------
1889
Georg Brandl3e483f62008-07-16 22:57:41 +00001890- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1891 its methods now allow for items objects that can be converted to
1892 an integer using operator.index().
1893
Mark Dickinson64b7e502008-07-16 09:40:03 +00001894- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1895 produced a ValueError instead of giving the correct float.
1896
Eric Smitha5fa5a22008-07-16 00:11:49 +00001897- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1898 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1899
Mark Dickinson7103aa42008-07-15 19:08:33 +00001900- Issue #3008: the float type has a new instance method 'float.hex'
1901 and a new class method 'float.fromhex' to convert floating-point
1902 numbers to and from hexadecimal strings, respectively.
1903
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001904- Issue #2235: __hash__ is once again inherited by default. To allow
1905 collections.Hashable to remain meaningful in the presence of the
1906 default hash implementation (object.__hash__), it is now possible
1907 to explicit block inheritance of hash by setting __hash__=None at
1908 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1909 level.
1910
Nick Coghlanb028f502008-07-13 14:52:36 +00001911- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1912 the parent module cannot be found while performing an absolute import.
1913 This means that an incorrectly defined __package__ attribute will
1914 now only prevent relative imports in that module rather than causing
1915 all imports from that module to fail.
1916
Nick Coghlan14ff9942008-07-08 14:21:42 +00001917- Issue #2517: Allow unicode messages in Exceptions again by correctly
1918 bypassing the instance dictionary when looking up __unicode__ on
1919 new-style classes.
1920
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001921- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1922 set to a custom object whose write() method happens to install
1923 another file in sys.stdout.
1924
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001925- Issue #3088: Corrected a race condition in classes derived from
1926 threading.local: the first member set by a thread could be saved in
1927 another thread's dictionary.
1928
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001929- Issue #3004: Minor change to slice.indices(): the start and stop
1930 arguments are now treated identically, making the behaviour easier
1931 to describe and understand. For example, slice(None, -10,
1932 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1933 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1934 10, -1).
1935
Georg Brandl278fc502008-07-19 12:46:12 +00001936- Issue #3219: Calling a function with repeated keyword arguments,
1937 f(a=2, a=23), would not cause a syntax error. This was a regression
1938 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001939
Georg Brandl278fc502008-07-19 12:46:12 +00001940- Issue #2862: Make int and float freelist management consistent with
1941 other freelists. Changes their CompactFreeList apis into
1942 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001943
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001944Library
1945-------
1946
Thomas Heller57adf222008-08-14 19:10:48 +00001947- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1948 api functions without holding the GIL, which could lead to a fatal
1949 error when they failed.
1950
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001951- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
1952

Jesse Noller13e9d582008-07-16 14:32:36 +00001959- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1960 ForkingPickler.register() to resolve conflict with ctypes.
1961
Vinay Sajip51e65192008-07-18 09:01:10 +00001962- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001963
Thomas Heller880f5292008-07-15 19:39:38 +00001964- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1965 a valid dlerror() message.
1966
Thomas Heller2bad6572008-07-15 17:19:50 +00001967- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1968 incomplete structure was created.
1969

1973
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001974- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001975
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001976- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1977 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001978 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001979 content-length. The problem had been corrected in the 2.4 branch, but never
1980 merged into trunk.
1981
Georg Brandle78fbcc2008-07-05 10:13:36 +00001982- Issue #2663: add filtering capability to shutil.copytree().

1988- Issue #1746: Correct handling of zipfile archive comments (previously
1989 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00001990 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00001991
Vinay Sajip51e65192008-07-18 09:01:10 +00001992- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001993 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00001994
Nick Coghlanc060b0e2008-07-02 13:09:19 +00001995- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1996 handling is now the same as that of other special attributes like __name__).
1997
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001998- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl3ee81df2008-05-17 18:14:43 +00002450- Issue #1631171: Re-implement the 'warnings' module in C (the
2451 original Python code has been kept as backup). This will allow for
2452 using the 'warning's machinery in such places as the parser where
2453 use of pure Python code is not possible. Both the ``showarning()``
2454 and ``formatwarning()`` gain an optional 'line' argument which is
2455 not called by default for backwards-compatibility reasons. Setting
2456 ``warnings.showwarning()`` to an implementation that lacks support
2457 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002520- Issue #2550: The approach used by client/server code for obtaining
2521 ports to listen on in network-oriented tests has been refined in an
2522 effort to facilitate running multiple instances of the entire
2523 regression test suite in parallel without issue.
2524 test_support.bind_port() has been fixed such that it will always
2525 return a unique port -- which wasn't always the case with the
2526 previous implementation, especially if socket options had been set
2527 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2528 new implementation of bind_port() will actually raise an exception
2529 if it is passed an AF_INET/SOCK_STREAM socket with either the
2530 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2531 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2532 the socket it's been passed. This currently only applies to
2533 Windows. This option prevents any other sockets from binding to the
2534 host/port we've bound to, thus removing the possibility of the
2535 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2536 when a second SOCK_STREAM socket binds and accepts to a host/port
2537 that's already been bound by another socket. The optional preferred
2538 port parameter to bind_port() has been removed. Under no
2539 circumstances should tests be hard coding ports!
2540
2541 test_support.find_unused_port() has also been introduced, which will
2542 pass a temporary socket object to bind_port() in order to obtain an
2543 unused port. The temporary socket object is then closed and
2544 deleted, and the port is returned. This method should only be used
2545 for obtaining an unused port in order to pass to an external program
2546 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2547 a parameter to a server-oriented class that doesn't give you direct
2548 access to the underlying socket used.
2549
2550 Finally, test_support.HOST has been introduced, which should be used
2551 for the host argument of any relevant socket calls (i.e. bind and
2552 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002553
2554 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002555 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002556 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2557 test_asynchat and test_socket_ssl.
2558
Georg Brandl3ee81df2008-05-17 18:14:43 +00002559 It is now possible for multiple instances of the regression test
2560 suite to run in parallel without issue.

2716 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00002717 platform.machine() and platform.processor() will report this
2718 information as well.

2827-----------------
2828
Fred Drakea8ee94b2008-03-01 02:45:07 +00002829- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002830 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002831
Georg Brandlad61bc82008-02-23 15:11:18 +00002832- Issue #2067: file.__exit__() now calls subclasses' close() method.
2833
2834- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002835
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002836- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002837 issue 215555 for a discussion.
2838
Eric Smitha73fbe72008-02-23 03:09:44 +00002839- Added the future_builtins module, which contains hex() and oct().
2840 These are the PEP 3127 version of these functions, designed to be
2841 compatible with the hex() and oct() builtins from Python 3.0. They
2842 differ slightly in their output formats from the existing, unchanged
2843 Python 2.6 builtins. The expected usage of the future_builtins
2844 module is:
2845 from future_builtins import hex, oct
2846
Eric Smith7ef40bf2008-02-20 23:34:22 +00002847- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2848 exponents for exponents with absolute value < 100. Follows C99
2849 standard. This is a change on Windows, which would use 3 digits.
2850 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2851 so that any alterations it does to the resulting string will be
2852 available in stringlib/formatter.h (for float.__format__).
2853
Eric Smith5a3c1352008-02-19 13:21:56 +00002854- Implemented PEP 3101, Advanced String Formatting. This adds a new
2855 builtin format(); a format() method for str and unicode; a
2856 __format__() method to object, str, unicode, int, long, float, and
2857 datetime; the class string.Formatter; and the C API
2858 PyObject_Format().
2859
Georg Brandl3ee81df2008-05-17 18:14:43 +00002860- Fixed several potential crashes, all caused by specially crafted
2861 __del__ methods exploiting objects in temporarily inconsistent
2862 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002863
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002864- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002865 prevent a possible crash: an Abstract Base Class would try to access
2866 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002867
Georg Brandl3ee81df2008-05-17 18:14:43 +00002868- Fixed repr() and str() of complex numbers with infinity or nan as
2869 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002871- Clear all free lists during a gc.collect() of the highest generation
2872 in order to allow pymalloc to free more arenas. Python may give back
2873 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002874
Georg Brandl3ee81df2008-05-17 18:14:43 +00002875- Issue #2045: Fix an infinite recursion triggered when printing a
2876 subclass of collections.defaultdict, if its default_factory is set
2877 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002878
Christian Heimesf75dbef2008-02-08 00:11:31 +00002879- Fixed a minor memory leak in dictobject.c. The content of the free
2880 list was not freed on interpreter shutdown.
2881
Georg Brandl5a7eca12010-03-21 19:29:04 +00002882- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00002883 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002884
Georg Brandl3ee81df2008-05-17 18:14:43 +00002885- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2886 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002887 to compact the internal free lists of pre-allocted ints and floats.
2888
Georg Brandl3ee81df2008-05-17 18:14:43 +00002889- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2890 calls. Python expected the return type int but the fork familie
2891 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002892
Georg Brandl3ee81df2008-05-17 18:14:43 +00002893- Issue #1678380: Fix a bug that identifies 0j and -0j when they

2903 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002904
Georg Brandl3ee81df2008-05-17 18:14:43 +00002905- Patch #1473257: generator objects gain a gi_code attribute. This is
2906 the same object as the func_code attribute of the function that
2907 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002908
Georg Brandl3ee81df2008-05-17 18:14:43 +00002909- Issue #1920: "while 0" statements were completely removed by the
2910 compiler, even in the presence of an "else" clause, which is
2911 supposed to be run when the condition is false. Now the compiler
2912 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002913
Guido van Rossumeead05f2008-01-24 18:21:02 +00002914- A few crashers fixed: weakref_in_del.py (issue #1377858);
2915 loosing_dict_ref.py (issue #1303614, test67.py);
2916 borrowed_ref_[34].py (not in tracker).
2917
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002918- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002919 suppressed while an extension is loaded by calling SetErrorMode in
2920 dynload_win.c. The error is still reported properly.
2921
Georg Brandl3ee81df2008-05-17 18:14:43 +00002922- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002923 several extension methods and modules do not work without unicode
2924 support.
2925
Georg Brandl26543b12008-01-21 18:36:51 +00002926- Issue #1882: when compiling code from a string, encoding cookies in the
2927 second line of code were not always recognized correctly.
2928
Georg Brandl14404b62008-01-19 19:27:05 +00002929- Issue #1679: "0x" was taken as a valid integer literal.
2930
Georg Brandl6caad7d2008-01-26 14:19:22 +00002931- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002932 added.
2933
Christian Heimesc94e2b52008-01-14 04:13:37 +00002934- sys.float_info / PyFloat_GetInfo: The floating point information
2935 object was converted from a dict to a specialized structseq object.
2936
Georg Brandl3ee81df2008-05-17 18:14:43 +00002937- Patch #1816: Added sys.flags structseq. It exposes the status of
2938 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002939
Georg Brandl3ee81df2008-05-17 18:14:43 +00002940- Objects/structseq.c: Implemented new structseq representation. The
2941 patch makes structseqs (e.g. the return value of os.stat) more
2942 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002943

Georg Brandl3ee81df2008-05-17 18:14:43 +00002952- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2953 envvar and sys.dont_write_bytecode attribute. All these can be set
2954 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002955
Georg Brandl3ee81df2008-05-17 18:14:43 +00002956- Improve some exception messages when Windows fails to load an
2957 extension module. Now we get for example '%1 is not a valid Win32
2958 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00002965- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002966 and INF. float("nan"), float("inf") and float("-inf") now work on
2967 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002969- Compiler now generates simpler and faster code for dictionary
2970 literals. The oparg for BUILD_MAP now indicates an estimated
2971 dictionary size. There is a new opcode, STORE_MAP, for adding
2972 entries to the dictionary.

3002 file can now be directly executed by passing their name to the
3003 interpreter. The directory/zipfile is automatically inserted as the
3004 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003006- Issue #1265: Fix a problem with sys.settrace, if the tracing
3007 function uses a generator expression when at the same time the
3008 executed code is closing a paused generator.

3015
Georg Brandl5a7eca12010-03-21 19:29:04 +00003016- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003017 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3018 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003019
Georg Brandl3ee81df2008-05-17 18:14:43 +00003020- Issue #1686386: Tuple's tp_repr did not take into account the
3021 possibility of having a self-referential tuple, which is possible
3022 from C code. Nor did object's tp_str consider that a type's tp_str
3023 could do something that could lead to an inifinite recursion.
3024 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3025 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003026
Georg Brandl3ee81df2008-05-17 18:14:43 +00003027- Issue #1164: It was possible to trigger deadlock when using the
3028 'print' statement to write to a file since the GIL was not released
3029 as needed. Now PyObject_Print() does the right thing along with
3030 various tp_print implementations of the built-in types and those in
3031 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003032
Georg Brandl3ee81df2008-05-17 18:14:43 +00003033- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannona0c05512007-09-10 21:38:27 +00003039
Brett Cannon1e534b52007-09-07 04:18:30 +00003040- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003041 PyObject_Call() never calling back out to Python code to trigger
3042 recursion depth updates/checks. Required the creation of a static
3043 RuntimeError instance in case normalizing an exception put the
3044 recursion check value past its limit. Fixes crashers
3045 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003046

Neal Norwitz0ac60192007-05-27 04:08:54 +00003060- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003061 __*__ attributes. (Some already existed, e.g., __doc__ and
3062 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003063
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003064- Add -3 option to the interpreter to warn about features that are

3066
Georg Brandl2134e752007-05-21 20:34:16 +00003067- Patch #1686487: you can now pass any mapping after '**' in function
3068 calls.
3069
Collin Winter62903052007-05-18 23:11:24 +00003070- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003071 "except E as target:". This is to provide forwards compatibility
3072 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00003079- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003080 setting a plain string, ie don't expand to single letter identifiers.
3081
Raymond Hettinger13936692007-04-11 18:40:58 +00003082- Request #1191699: Slices can now be pickled.
3083
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003084- Request #1193128: str.translate() now allows a None argument for
3085 translations that only remove characters without re-mapping the
3086 remaining characters.
3087
Georg Brandl5cb76c12007-03-21 09:00:39 +00003088- Patch #1682205: a TypeError while unpacking an iterable is no longer

3092
Guido van Rossum143b5642007-03-23 04:58:42 +00003093- Bug #1683368: The object.__init__() and object.__new__() methods are
3094 now stricter in rejecting excess arguments. The only time when
3095 either allows excess arguments is when it is not overridden and the
3096 other one is. For backwards compatibility, when both are
3097 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003098 warning later). Also, type.__init__() insists on the same signature
3099 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003100
Georg Brandl3ee81df2008-05-17 18:14:43 +00003101- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3102 object to complex using its __complex__() method before falling back
3103 to the __float__() method. Therefore, the functions in the cmath
3104 module now can operate on objects that define a __complex__()
3105 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003106
Georg Brandl3ee81df2008-05-17 18:14:43 +00003107- Patch #1623563: allow __class__ assignment for classes with
3108 __slots__. The old and the new class are still required to have the
3109 same slot names.

3116 its type.

3122
Georg Brandl7b9c5552007-03-12 14:30:05 +00003123- Bug #1678647: write a newline after printing an exception in any
3124 case, even when converting the value to a string failed.
3125
Georg Brandl871f1bc2007-03-12 13:17:36 +00003126- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003127 its argument, if it exists. If not, it will work like before. This
3128 allows customizing the output of dir() in the presence of a
3129 __getattr__().

3138 parthensized forms. This means complex(repr(x)) now works instead of
3139 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003140
Georg Brandlaa2321b2007-03-07 00:40:28 +00003141- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003142 makes the filenames the warning module prints much more sensible
3143 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003144

Georg Brandl0fca97a2007-03-05 22:28:08 +00003156- Patch #1674228: when assigning a slice (old-style), check for the
3157 sq_ass_slice instead of the sq_slice slot.
3158
Georg Brandl3ee81df2008-05-17 18:14:43 +00003159- When printing an unraisable error, don't print exceptions. before
3160 the name. This duplicates the behavior whening normally printing
3161 exceptions.

Guido van Rossum8bc09652008-02-21 18:18:37 +00003303- Removed uses of dict.has_key() from distutils, and uses of

Georg Brandl3ee81df2008-05-17 18:14:43 +00003694 AttributeError instead of an IOError when the server's response
3695 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003696

Georg Brandl3ee81df2008-05-17 18:14:43 +00003712- Patch #1530482: add pydoc.render_doc() which returns the

3727
Georg Brandl92a6bae2007-03-13 17:43:32 +00003728- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003729 are set for invalid interpolation sequences that would lead to
3730 errors on reading back those values.

3786 TestCase and TestSuite subclasses (not instances) are no longer
3787 accepted in TestSuite.addTest(). This should cause no
3788 incompatibility since it never made sense with ordinary subclasses
3789 -- the failure just occurred later, with a more cumbersome
3790 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004179 time so that opening a database previously created with the DB_DUP
4180 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4181 opens. Specifically: dictionary assignment to a DB object will
4182 replace all values for a given key when the database allows
4183 duplicate values. DB users should use DB.put(k, v) when they want
4184 to store duplicates; not DB[k] = v.

4191 characters with ASCII value less than 32. Also, it correctly quotes
4192 dots only if they occur on a single line, as opposed to the previous
4193 behavior of quoting dots if they are the second character of any
4194 line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004464 periodic threadstate and signal checking in tight loops. By
4465 default, this option is turned-off. It should only be enabled in

4540 of w# format code incorrectly truncated the length to an int, even
4541 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4542 incorrect results with huge strings.

4566 outside of pystate.c and should not be necessary.
4567
Georg Brandl3ee81df2008-05-17 18:14:43 +00004568- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4569 absolute imports. In earlier versions they might have used relative
4570 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004571
Georg Brandl3ee81df2008-05-17 18:14:43 +00004572- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4573 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
