1347What's New in Python 2.6.1
1348==========================
1349
1350*Release date: 04-Dec-2008*
1351
1352Core and Builtins
1353-----------------
1354
1355- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1356 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1357 instead of throwing a MemoryError.
1358
1359- Issue #4367: Python would segfault during compiling when the unicodedata
1360 module couldn't be imported and \N escapes were present.
1361
1362- Issue #4348: Some bytearray methods returned that didn't cause any change to
1363 the bytearray, returned the same bytearray instead of a copy.
1364
1365- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1366
1367- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1368
1369- Issue #4048: The parser module now correctly validates relative imports.
1370
1371- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

1377- Issue #4209: Enabling unicode_literals and the print_function in the same
1378 __future__ import didn't work.
1379
1380- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1381 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1382 really executed because I cannot move to such directory on win2k)
1383
1384- Issue #4069: When set.remove(element) is used with a set element, the element
1385 is temporarily replaced with an equivalent frozenset. But the eventual
1386 KeyError would always report the empty frozenset([]) as the missing key. Now
1387 it correctly refers to the initial element.
1388
1389- Fixed C99 style comments in several files. Python is now C89 compatible
1390 again.

1538
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001539- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1540 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1541 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1542 ``printf`` function, whereas PyString_FromFormat has an independent
1543 implementation and uses "%zd" on all platforms for size_t values.
1544 This makes a difference on win64, where ``printf`` needs "%Id" to display
1545 64bit values.

1640 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1641 for catch_warnings() also led to an improvement in the raising of a
1642 DeprecationWarning related to warnings.warn_explicit().

1663
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001664- Issue #2975: When compiling several extension modules with Visual Studio 2008
1665 from the same python interpreter, some environment variables would grow
1666 without limit.
1667
Benjamin Peterson37346b22008-08-23 20:27:43 +00001668- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001705What's New in Python 2.6 beta 3?
1706================================
1707
Barry Warsaw07a4a382008-08-21 01:15:08 +00001708*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001709
1710Core and Builtins
1711-----------------
1712
Guido van Rossumf8402962008-08-20 15:01:50 +00001713- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1714 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1715 extensions do not automatically benefit from the class attribute
1716 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1717 to their tp_flags field if they care. This is a backwards
1718 compatibility feature; in 3.0, all types will use the cache by
1719 default.
1720
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001721- Keyword arguments can now follow starred arguments. (``f(a, *args,
1722 keyword=23)`` is now valid syntax.)
1723
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001724- ctypes function pointers that are COM methods have a boolean True
1725 value again.
1726
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001727- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1728 by denying s# to parse objects that have a releasebuffer procedure,
1729 and introducing s*.
1730
Georg Brandl1e13ea92008-08-11 09:07:59 +00001731- Issue #3537: Fix an assertion failure when an empty but presized dict
1732 object was stored in the freelist.
1733
Mark Dickinsonb6467572008-08-04 21:30:09 +00001734- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1735 ValueError consistently across platforms.
1736
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001737- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1738 (64bit Unix, for example), unichr() would truncate its argument and return
1739 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1740
Neal Norwitze7d8be82008-07-31 17:17:14 +00001741- Apply security patches from Apple.
1742
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001743- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1744 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1745
Antoine Pitrou92f82162008-07-25 22:22:08 +00001746- Issue #1819: function calls with several named parameters are now on
1747 average 35% faster (as measured by pybench).
1748
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001749- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1750 the python debugger steps into a class statement: the free variables (local
1751 variables defined in an outer scope) would be deleted from the outer scope.
1752
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001753- Issue #2620: Overflow checking when allocating or reallocating memory
1754 was not always being done properly in some python types and extension
1755 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1756 all been updated to perform better checks and places in the code that
1757 would previously leak memory on the error path when such an allocation
1758 failed have been fixed.

1761-------
1762
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001763- Issue #3612: Added some missing basic types in ctypes.wintypes.
1764
Benjamin Petersone977ad42008-08-20 01:42:01 +00001765- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1766 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1767
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001768- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1769 version reported by these tools does not necessarily follow the python
1770 version numbering scheme, so the module is less strict when parsing it.
1771
Nick Coghlanf70385a2008-08-18 12:42:46 +00001772- Issue #2235: Added Py3k warnings for types which will become unhashable
1773 under the stricter __hash__ inheritance rules in 3.0. Several types
1774 which did not meet the rules for hash invariants and were already
1775 unhashable in 3.0 have now been explicitly flagged as unhashable in
1776 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1777 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1778
Brett Cannon88f801d2008-08-18 00:46:22 +00001779- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1780 imported into the module but exposed as part of the module's API.
1781
Brett Cannon7b96f072008-08-18 00:41:11 +00001782- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1783
Brett Cannon46225e72008-08-18 00:36:52 +00001784- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001786- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1787
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001788- Issue #3575: Incremental decoder's decode function now takes bytearray
1789 by using 's*' instead of 't#'.
1790
Jesus Cea585ad8a2009-07-02 15:37:21 +00001791- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001792 fails unicode conversion on 2nd parameter. (windows only)
1793
Facundo Batista94f243a2008-08-17 03:38:39 +00001794- Issue 2464. urllib2 now supports a malformation in the URL received
1795 in a redirect.
1796
Brett Cannonabe423e2008-08-16 21:47:07 +00001797- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001798 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001799
Facundo Batistaeb90b782008-08-16 14:44:07 +00001800- Issue #2776: fixed small issue when handling an URL with double slash
1801 after a 302 response in the case of not going through a proxy.
1802
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001803- Issue #2676: in the email package, content-type parsing was hanging on
1804 pathological input because of quadratic or exponential behaviour of a
1805 regular expression.
1806
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001807- Issue #3476: binary buffered reading through the new "io" library is now
1808 thread-safe.
1809
Brett Cannonbf3157b2008-08-14 05:00:03 +00001810- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1811 since mimetools itself is deprecated. Because modules are cached, all
1812 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1813
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001814- Issue #3134: shutil referenced undefined WindowsError symbol.
1815
Robert Schuppenies14646332008-08-10 11:01:53 +00001816- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1817 menu entries were not deleted.
1818
Brett Cannon83e81842008-08-09 23:30:55 +00001819- Copied the implementation of reduce() to _functools.reduce() to have a
1820 version that did not raise a DeprecationWarning under -3.
1821
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001822- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1823 a MemoryError rather than silently stop the iteration.
1824
Guido van Rossum59ce9012008-08-09 14:55:34 +00001825- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1826 to _sre.compile() will now be rejected. This should not affect anybody
1827 since the re.compile() function never generates invalid re-bytecode.
1828
Skip Montanaroa032bf42008-08-08 22:52:51 +00001829- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1830 upon first access it can be automatically initialized from the csv file if
1831 it wasn't initialized during instantiation.
1832
Brett Cannon3aa2a492008-08-06 22:28:09 +00001833- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1834 the reload() built-in has been removed.
1835
Brett Cannon7e30b672008-08-04 21:52:25 +00001836- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001837 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001848 asking for a specific length. This problem only affected files opened
1849 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001850

1875 file name rather than a ZipInfo instance, so files are extracted with
1876 mode 0600 rather than 000 under Unix.
1877
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001878- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1879 argument in python 2.5, this broke code that subclassed Popen to include its
1880 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001893- Issue #643841: The language reference now provides more detailed
1894 coverage of the lookup process for special methods. The disclaimers
1895 regarding lack of coverage of new-style classes have also been

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001899What's New in Python 2.6 beta 2?
1900================================
1901
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001902*Release date: 17-Jul-2008*
1903
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001904Core and Builtins
1905-----------------
1906
Georg Brandl3e483f62008-07-16 22:57:41 +00001907- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1908 its methods now allow for items objects that can be converted to
1909 an integer using operator.index().
1910
Mark Dickinson64b7e502008-07-16 09:40:03 +00001911- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1912 produced a ValueError instead of giving the correct float.
1913
Eric Smitha5fa5a22008-07-16 00:11:49 +00001914- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1915 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1916
Mark Dickinson7103aa42008-07-15 19:08:33 +00001917- Issue #3008: the float type has a new instance method 'float.hex'
1918 and a new class method 'float.fromhex' to convert floating-point
1919 numbers to and from hexadecimal strings, respectively.
1920
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001921- Issue #2235: __hash__ is once again inherited by default. To allow
1922 collections.Hashable to remain meaningful in the presence of the
1923 default hash implementation (object.__hash__), it is now possible
1924 to explicit block inheritance of hash by setting __hash__=None at
1925 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1926 level.
1927
Nick Coghlanb028f502008-07-13 14:52:36 +00001928- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1929 the parent module cannot be found while performing an absolute import.
1930 This means that an incorrectly defined __package__ attribute will
1931 now only prevent relative imports in that module rather than causing
1932 all imports from that module to fail.
1933
Nick Coghlan14ff9942008-07-08 14:21:42 +00001934- Issue #2517: Allow unicode messages in Exceptions again by correctly
1935 bypassing the instance dictionary when looking up __unicode__ on
1936 new-style classes.
1937
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001938- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1939 set to a custom object whose write() method happens to install
1940 another file in sys.stdout.
1941
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001942- Issue #3088: Corrected a race condition in classes derived from
1943 threading.local: the first member set by a thread could be saved in
1944 another thread's dictionary.
1945
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001946- Issue #3004: Minor change to slice.indices(): the start and stop
1947 arguments are now treated identically, making the behaviour easier
1948 to describe and understand. For example, slice(None, -10,
1949 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1950 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1951 10, -1).
1952
Georg Brandl278fc502008-07-19 12:46:12 +00001953- Issue #3219: Calling a function with repeated keyword arguments,
1954 f(a=2, a=23), would not cause a syntax error. This was a regression
1955 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001956
Georg Brandl278fc502008-07-19 12:46:12 +00001957- Issue #2862: Make int and float freelist management consistent with
1958 other freelists. Changes their CompactFreeList apis into
1959 ClearFreeList apis and calls them via gc.collect().

1963
Thomas Heller57adf222008-08-14 19:10:48 +00001964- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1965 api functions without holding the GIL, which could lead to a fatal
1966 error when they failed.
1967
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001968- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00001976- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1977 ForkingPickler.register() to resolve conflict with ctypes.
1978
Vinay Sajip51e65192008-07-18 09:01:10 +00001979- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001980
Thomas Heller880f5292008-07-15 19:39:38 +00001981- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1982 a valid dlerror() message.
1983
Thomas Heller2bad6572008-07-15 17:19:50 +00001984- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1985 incomplete structure was created.

1990
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001991- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001992
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001993- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1994 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001995 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001996 content-length. The problem had been corrected in the 2.4 branch, but never
1997 merged into trunk.
1998
Georg Brandle78fbcc2008-07-05 10:13:36 +00001999- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002010 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00002011
Nick Coghlanc060b0e2008-07-02 13:09:19 +00002012- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2013 handling is now the same as that of other special attributes like __name__).
2014
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002015- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
2016 removal in Python 3.0 in favor of urllib2.urlopen().

2472 not called by default for backwards-compatibility reasons. Setting
2473 ``warnings.showwarning()`` to an implementation that lacks support

Georg Brandl3ee81df2008-05-17 18:14:43 +00002537- Issue #2550: The approach used by client/server code for obtaining
2538 ports to listen on in network-oriented tests has been refined in an
2539 effort to facilitate running multiple instances of the entire
2540 regression test suite in parallel without issue.
2541 test_support.bind_port() has been fixed such that it will always
2542 return a unique port -- which wasn't always the case with the
2543 previous implementation, especially if socket options had been set
2544 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2545 new implementation of bind_port() will actually raise an exception
2546 if it is passed an AF_INET/SOCK_STREAM socket with either the
2547 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2548 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2549 the socket it's been passed. This currently only applies to
2550 Windows. This option prevents any other sockets from binding to the
2551 host/port we've bound to, thus removing the possibility of the
2552 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2553 when a second SOCK_STREAM socket binds and accepts to a host/port
2554 that's already been bound by another socket. The optional preferred
2555 port parameter to bind_port() has been removed. Under no
2556 circumstances should tests be hard coding ports!
2557
2558 test_support.find_unused_port() has also been introduced, which will
2559 pass a temporary socket object to bind_port() in order to obtain an
2560 unused port. The temporary socket object is then closed and
2561 deleted, and the port is returned. This method should only be used
2562 for obtaining an unused port in order to pass to an external program
2563 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2564 a parameter to a server-oriented class that doesn't give you direct
2565 access to the underlying socket used.
2566
2567 Finally, test_support.HOST has been introduced, which should be used
2568 for the host argument of any relevant socket calls (i.e. bind and
2569 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002570
2571 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002572 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

2574 test_asynchat and test_socket_ssl.
2575
Georg Brandl3ee81df2008-05-17 18:14:43 +00002576 It is now possible for multiple instances of the regression test
2577 suite to run in parallel without issue.

2845
Fred Drakea8ee94b2008-03-01 02:45:07 +00002846- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002847 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002852
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002853- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002854 issue 215555 for a discussion.
2855
Eric Smitha73fbe72008-02-23 03:09:44 +00002856- Added the future_builtins module, which contains hex() and oct().
2857 These are the PEP 3127 version of these functions, designed to be
2858 compatible with the hex() and oct() builtins from Python 3.0. They
2859 differ slightly in their output formats from the existing, unchanged
2860 Python 2.6 builtins. The expected usage of the future_builtins
2861 module is:
2862 from future_builtins import hex, oct
2863
Eric Smith7ef40bf2008-02-20 23:34:22 +00002864- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2865 exponents for exponents with absolute value < 100. Follows C99
2866 standard. This is a change on Windows, which would use 3 digits.
2867 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2868 so that any alterations it does to the resulting string will be
2869 available in stringlib/formatter.h (for float.__format__).
2870
Eric Smith5a3c1352008-02-19 13:21:56 +00002871- Implemented PEP 3101, Advanced String Formatting. This adds a new
2872 builtin format(); a format() method for str and unicode; a
2873 __format__() method to object, str, unicode, int, long, float, and
2874 datetime; the class string.Formatter; and the C API
2875 PyObject_Format().
2876
Georg Brandl3ee81df2008-05-17 18:14:43 +00002877- Fixed several potential crashes, all caused by specially crafted
2878 __del__ methods exploiting objects in temporarily inconsistent
2879 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002880
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002881- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002882 prevent a possible crash: an Abstract Base Class would try to access
2883 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002888- Clear all free lists during a gc.collect() of the highest generation
2889 in order to allow pymalloc to free more arenas. Python may give back
2890 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002891
Georg Brandl3ee81df2008-05-17 18:14:43 +00002892- Issue #2045: Fix an infinite recursion triggered when printing a
2893 subclass of collections.defaultdict, if its default_factory is set
2894 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002895
Christian Heimesf75dbef2008-02-08 00:11:31 +00002896- Fixed a minor memory leak in dictobject.c. The content of the free
2897 list was not freed on interpreter shutdown.
2898
Georg Brandl5a7eca12010-03-21 19:29:04 +00002899- Limit free list of method and built-in function objects to 256

2903 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002904 to compact the internal free lists of pre-allocted ints and floats.
2905
Georg Brandl3ee81df2008-05-17 18:14:43 +00002906- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2907 calls. Python expected the return type int but the fork familie
2908 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002922- Patch #1473257: generator objects gain a gi_code attribute. This is
2923 the same object as the func_code attribute of the function that
2924 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002925
Georg Brandl3ee81df2008-05-17 18:14:43 +00002926- Issue #1920: "while 0" statements were completely removed by the
2927 compiler, even in the presence of an "else" clause, which is
2928 supposed to be run when the condition is false. Now the compiler
2929 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002930

Georg Brandl6caad7d2008-01-26 14:19:22 +00002948- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002949 added.
2950
Christian Heimesc94e2b52008-01-14 04:13:37 +00002951- sys.float_info / PyFloat_GetInfo: The floating point information

Christian Heimesf31b69f2008-01-14 03:42:48 +00002956
Georg Brandl3ee81df2008-05-17 18:14:43 +00002957- Objects/structseq.c: Implemented new structseq representation. The
2958 patch makes structseqs (e.g. the return value of os.stat) more
2959 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002960
Georg Brandl3ee81df2008-05-17 18:14:43 +00002961- Patch #1700288: added a type attribute cache that caches method
2962 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002963
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002964- Bug #1776: __import__() no longer accepts filenames on any platform.
2965 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002966
Georg Brandlaed6c662008-01-07 17:25:53 +00002967- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2968
Georg Brandl3ee81df2008-05-17 18:14:43 +00002969- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2970 envvar and sys.dont_write_bytecode attribute. All these can be set
2971 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002972
Georg Brandl3ee81df2008-05-17 18:14:43 +00002973- Improve some exception messages when Windows fails to load an
2974 extension module. Now we get for example '%1 is not a valid Win32
2975 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002976
Georg Brandl3ee81df2008-05-17 18:14:43 +00002977- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002979- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2980 y) functions.

Christian Heimes0a8143f2007-12-18 23:22:54 +00002982- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002983 and INF. float("nan"), float("inf") and float("-inf") now work on
2984 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002985
Georg Brandl3ee81df2008-05-17 18:14:43 +00002986- Compiler now generates simpler and faster code for dictionary
2987 literals. The oparg for BUILD_MAP now indicates an estimated
2988 dictionary size. There is a new opcode, STORE_MAP, for adding
2989 entries to the dictionary.

3001
Nick Coghlanef01d822007-12-03 12:55:17 +00003002- PEP 366: Allow explicit relative imports when executing modules

3007 running, and if the deallocation of its frames somehow calls the
3008 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003009

Georg Brandl3ee81df2008-05-17 18:14:43 +00003018- Patch #1739468: Directories and zipfiles containing a __main__.py
3019 file can now be directly executed by passing their name to the
3020 interpreter. The directory/zipfile is automatically inserted as the
3021 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003022
Georg Brandl3ee81df2008-05-17 18:14:43 +00003023- Issue #1265: Fix a problem with sys.settrace, if the tracing
3024 function uses a generator expression when at the same time the
3025 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003026
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003027- sets and frozensets now have an isdisjoint() method.
3028
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003029- optimize the performance of builtin.sum().
3030
Neal Norwitz44f326e2007-10-05 05:29:17 +00003031- Fix warnings found by the new version of the Coverity checker.
3032
Georg Brandl5a7eca12010-03-21 19:29:04 +00003033- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003034 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3035 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003036
Georg Brandl3ee81df2008-05-17 18:14:43 +00003037- Issue #1686386: Tuple's tp_repr did not take into account the
3038 possibility of having a self-referential tuple, which is possible
3039 from C code. Nor did object's tp_str consider that a type's tp_str
3040 could do something that could lead to an inifinite recursion.
3041 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3042 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003043
Georg Brandl3ee81df2008-05-17 18:14:43 +00003044- Issue #1164: It was possible to trigger deadlock when using the
3045 'print' statement to write to a file since the GIL was not released
3046 as needed. Now PyObject_Print() does the right thing along with
3047 various tp_print implementations of the built-in types and those in
3048 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003049
Georg Brandl3ee81df2008-05-17 18:14:43 +00003050- Issue #1147: Exceptions were directly allowing string exceptions in
3051 their throw() method even though string exceptions no longer
3052 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00003056
Brett Cannon1e534b52007-09-07 04:18:30 +00003057- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003058 PyObject_Call() never calling back out to Python code to trigger
3059 recursion depth updates/checks. Required the creation of a static
3060 RuntimeError instance in case normalizing an exception put the
3061 recursion check value past its limit. Fixes crashers
3062 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003063
Georg Brandl3ee81df2008-05-17 18:14:43 +00003064- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003077- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003078 __*__ attributes. (Some already existed, e.g., __doc__ and
3079 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003080
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003081- Add -3 option to the interpreter to warn about features that are
3082 deprecated and will be changed/removed in Python 3.0.
3083
Georg Brandl2134e752007-05-21 20:34:16 +00003084- Patch #1686487: you can now pass any mapping after '**' in function
3085 calls.
3086
Collin Winter62903052007-05-18 23:11:24 +00003087- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003088 "except E as target:". This is to provide forwards compatibility
3089 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00003091- Deprecate BaseException.message as per PEP 352.
3092
Georg Brandl3ee81df2008-05-17 18:14:43 +00003093- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003094 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003095
Vinay Sajip8549ce32007-05-06 17:53:37 +00003096- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003097 setting a plain string, ie don't expand to single letter identifiers.
3098
Raymond Hettinger13936692007-04-11 18:40:58 +00003099- Request #1191699: Slices can now be pickled.
3100
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003101- Request #1193128: str.translate() now allows a None argument for
3102 translations that only remove characters without re-mapping the
3103 remaining characters.
3104
Georg Brandl5cb76c12007-03-21 09:00:39 +00003105- Patch #1682205: a TypeError while unpacking an iterable is no longer
3106 masked by a generic one with the message "unpack non-sequence".
3107
Neal Norwitzaa754b72007-03-21 06:39:48 +00003108- Remove unused file Python/fmod.c.
3109
Guido van Rossum143b5642007-03-23 04:58:42 +00003110- Bug #1683368: The object.__init__() and object.__new__() methods are
3111 now stricter in rejecting excess arguments. The only time when
3112 either allows excess arguments is when it is not overridden and the
3113 other one is. For backwards compatibility, when both are
3114 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003115 warning later). Also, type.__init__() insists on the same signature
3116 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003117
Georg Brandl3ee81df2008-05-17 18:14:43 +00003118- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3119 object to complex using its __complex__() method before falling back
3120 to the __float__() method. Therefore, the functions in the cmath
3121 module now can operate on objects that define a __complex__()
3122 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003123
Georg Brandl3ee81df2008-05-17 18:14:43 +00003124- Patch #1623563: allow __class__ assignment for classes with
3125 __slots__. The old and the new class are still required to have the
3126 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003127

3139
Georg Brandl7b9c5552007-03-12 14:30:05 +00003140- Bug #1678647: write a newline after printing an exception in any
3141 case, even when converting the value to a string failed.
3142
Georg Brandl871f1bc2007-03-12 13:17:36 +00003143- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003144 its argument, if it exists. If not, it will work like before. This
3145 allows customizing the output of dir() in the presence of a
3146 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003154- Patch #1491866: change the complex() constructor to allow
3155 parthensized forms. This means complex(repr(x)) now works instead of
3156 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003157
Georg Brandlaa2321b2007-03-07 00:40:28 +00003158- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003159 makes the filenames the warning module prints much more sensible
3160 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003161

3163 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003164 variable is given, but break into the interactive interpreter just
3165 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003173- Patch #1674228: when assigning a slice (old-style), check for the
3174 sq_ass_slice instead of the sq_slice slot.
3175
Georg Brandl3ee81df2008-05-17 18:14:43 +00003176- When printing an unraisable error, don't print exceptions. before
3177 the name. This duplicates the behavior whening normally printing
3178 exceptions.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00003680- Added a timeout parameter to the constructor of other protocols
3681 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3682 work started with create_connection() and timeout in httplib, and
3683 closes patch #723312.
3684
Vinay Sajip8549ce32007-05-06 17:53:37 +00003685- Patch #1676823: Added create_connection() to socket.py, which may be
3686 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00003687 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00003688
Martin v. Löwis0af33882007-03-23 13:27:15 +00003689- Bug #978833: Revert r50844, as it broke _socketobject.dup.

3701 GNOME or KDE browser, depending on whether there is a session of one

3709
Georg Brandlf66b6032007-03-14 08:27:52 +00003710- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00003711 AttributeError instead of an IOError when the server's response
3712 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003713
Georg Brandl3ee81df2008-05-17 18:14:43 +00003714- Patch #957650: "%var%" environment variable references are now
3715 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl3ee81df2008-05-17 18:14:43 +00003718- Patch #1429539: pdb now correctly initializes the __main__ module
3719 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003720 correctly now.
3721
Georg Brandlbad6f192007-03-13 21:32:56 +00003722- The nonobvious commands.getstatus() function is now deprecated.

3728
Georg Brandl3ee81df2008-05-17 18:14:43 +00003729- Patch #1530482: add pydoc.render_doc() which returns the
3730 documentation for a thing instead of paging it to stdout, which
3731 pydoc.doc() does.

3739 parameter which can be set to False to prevent the default
3740 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00003741
Georg Brandl9e6b4702007-03-13 18:15:41 +00003742- Patch #1581073: add a flag to textwrap that prevents the dropping of
3743 whitespace while wrapping.
3744
Georg Brandl92a6bae2007-03-13 17:43:32 +00003745- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003746 are set for invalid interpolation sequences that would lead to
3747 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00003748

Georg Brandl94fe3f52007-03-13 09:32:11 +00003762- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00003763 field names in its exception message if you try to write a record
3764 with a dictionary containing fields not in the CSV field names list.

3790 returned string up to the first NUL character.
3791

3801
Georg Brandl3ee81df2008-05-17 18:14:43 +00003802- unittest now verifies more of its assumptions. In particular,
3803 TestCase and TestSuite subclasses (not instances) are no longer
3804 accepted in TestSuite.addTest(). This should cause no
3805 incompatibility since it never made sense with ordinary subclasses
3806 -- the failure just occurred later, with a more cumbersome
3807 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00003808

3816 given a unicode argument and os.listdir() returns unicode filenames.
3817
Georg Brandl3ee81df2008-05-17 18:14:43 +00003818- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00004196 time so that opening a database previously created with the DB_DUP
4197 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4198 opens. Specifically: dictionary assignment to a DB object will
4199 replace all values for a given key when the database allows
4200 duplicate values. DB users should use DB.put(k, v) when they want
4201 to store duplicates; not DB[k] = v.

4208 characters with ASCII value less than 32. Also, it correctly quotes
4209 dots only if they occur on a single line, as opposed to the previous
4210 behavior of quoting dots if they are the second character of any
4211 line.
