1000
Benjamin Petersonc6e80eb2008-12-21 17:01:26 +00001001- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

1007
Vinay Sajip6badbe92009-01-20 22:49:13 +00001008- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Georg Brandld2094602008-12-05 08:51:30 +00001009 method on file objects with closefd=False. The file descriptor is still
1010 kept open but the file object behaves like a closed file. The ``FileIO``
1011 object also got a new readonly attribute ``closefd``.
1012
Georg Brandlfa71a902008-12-05 09:08:28 +00001013- Issue #3689: The list reversed iterator now supports __length_hint__

Jesse Nollerb48cfa62009-03-30 16:19:10 +00001081 socket.SO_REUSEADDR on all connections so that the user no longer needs

1219 zipimport (or any other conformant PEP 302 loader). Original patch by

1221
1222- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
1223 302 conformant loader) will now work correctly in most cases (they
1224 are still subject to the constraints that exist for all code running
1225 from inside a module loaded via a PEP 302 loader and attempting to

1384What's New in Python 2.6.1
1385==========================
1386
1387*Release date: 04-Dec-2008*
1388
1389Core and Builtins
1390-----------------
1391
1392- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1393 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1394 instead of throwing a MemoryError.
1395
1396- Issue #4367: Python would segfault during compiling when the unicodedata
1397 module couldn't be imported and \N escapes were present.
1398
1399- Issue #4348: Some bytearray methods returned that didn't cause any change to
1400 the bytearray, returned the same bytearray instead of a copy.
1401
1402- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1403
1404- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1405
1406- Issue #4048: The parser module now correctly validates relative imports.
1407
1408- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

1413
1414- Issue #4209: Enabling unicode_literals and the print_function in the same
1415 __future__ import didn't work.
1416
1417- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1418 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1419 really executed because I cannot move to such directory on win2k)
1420
1421- Issue #4069: When set.remove(element) is used with a set element, the element
1422 is temporarily replaced with an equivalent frozenset. But the eventual
1423 KeyError would always report the empty frozenset([]) as the missing key. Now
1424 it correctly refers to the initial element.
1425
1426- Fixed C99 style comments in several files. Python is now C89 compatible
1427 again.

Vinay Sajip35e3b032008-09-01 14:33:59 +00001601- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001602 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1603 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1604 when given a tuple of classes as second argument, were looking up
1605 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1606 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001742What's New in Python 2.6 beta 3?
1743================================
1744
Barry Warsaw07a4a382008-08-21 01:15:08 +00001745*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001746
1747Core and Builtins
1748-----------------
1749
Guido van Rossumf8402962008-08-20 15:01:50 +00001750- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1751 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1752 extensions do not automatically benefit from the class attribute
1753 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1754 to their tp_flags field if they care. This is a backwards
1755 compatibility feature; in 3.0, all types will use the cache by
1756 default.
1757
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001758- Keyword arguments can now follow starred arguments. (``f(a, *args,
1759 keyword=23)`` is now valid syntax.)
1760
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001761- ctypes function pointers that are COM methods have a boolean True
1762 value again.
1763
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001764- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1765 by denying s# to parse objects that have a releasebuffer procedure,
1766 and introducing s*.
1767
Georg Brandl1e13ea92008-08-11 09:07:59 +00001768- Issue #3537: Fix an assertion failure when an empty but presized dict
1769 object was stored in the freelist.
1770
Mark Dickinsonb6467572008-08-04 21:30:09 +00001771- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1772 ValueError consistently across platforms.
1773
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001774- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1775 (64bit Unix, for example), unichr() would truncate its argument and return
1776 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1777
Neal Norwitze7d8be82008-07-31 17:17:14 +00001778- Apply security patches from Apple.
1779
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001780- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1781 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1782
Antoine Pitrou92f82162008-07-25 22:22:08 +00001783- Issue #1819: function calls with several named parameters are now on
1784 average 35% faster (as measured by pybench).
1785
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001786- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1787 the python debugger steps into a class statement: the free variables (local
1788 variables defined in an outer scope) would be deleted from the outer scope.
1789
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001790- Issue #2620: Overflow checking when allocating or reallocating memory
1791 was not always being done properly in some python types and extension
1792 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1793 all been updated to perform better checks and places in the code that
1794 would previously leak memory on the error path when such an allocation
1795 failed have been fixed.

1799
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001800- Issue #3612: Added some missing basic types in ctypes.wintypes.
1801
Benjamin Petersone977ad42008-08-20 01:42:01 +00001802- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1803 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1804
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001805- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1806 version reported by these tools does not necessarily follow the python
1807 version numbering scheme, so the module is less strict when parsing it.
1808
Nick Coghlanf70385a2008-08-18 12:42:46 +00001809- Issue #2235: Added Py3k warnings for types which will become unhashable
1810 under the stricter __hash__ inheritance rules in 3.0. Several types
1811 which did not meet the rules for hash invariants and were already
1812 unhashable in 3.0 have now been explicitly flagged as unhashable in
1813 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1814 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1815
Brett Cannon88f801d2008-08-18 00:46:22 +00001816- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1817 imported into the module but exposed as part of the module's API.
1818
Brett Cannon7b96f072008-08-18 00:41:11 +00001819- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1820
Brett Cannon46225e72008-08-18 00:36:52 +00001821- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1822
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001823- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1824
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001825- Issue #3575: Incremental decoder's decode function now takes bytearray
1826 by using 's*' instead of 't#'.
1827
Jesus Cea585ad8a2009-07-02 15:37:21 +00001828- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001829 fails unicode conversion on 2nd parameter. (windows only)
1830
Facundo Batista94f243a2008-08-17 03:38:39 +00001831- Issue 2464. urllib2 now supports a malformation in the URL received
1832 in a redirect.
1833
Brett Cannonabe423e2008-08-16 21:47:07 +00001834- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001835 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001836
Facundo Batistaeb90b782008-08-16 14:44:07 +00001837- Issue #2776: fixed small issue when handling an URL with double slash
1838 after a 302 response in the case of not going through a proxy.
1839
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001840- Issue #2676: in the email package, content-type parsing was hanging on
1841 pathological input because of quadratic or exponential behaviour of a
1842 regular expression.
1843
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001844- Issue #3476: binary buffered reading through the new "io" library is now
1845 thread-safe.
1846
Brett Cannonbf3157b2008-08-14 05:00:03 +00001847- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1848 since mimetools itself is deprecated. Because modules are cached, all
1849 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1850
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001851- Issue #3134: shutil referenced undefined WindowsError symbol.
1852
Robert Schuppenies14646332008-08-10 11:01:53 +00001853- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1854 menu entries were not deleted.
1855
Brett Cannon83e81842008-08-09 23:30:55 +00001856- Copied the implementation of reduce() to _functools.reduce() to have a
1857 version that did not raise a DeprecationWarning under -3.
1858
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001859- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1860 a MemoryError rather than silently stop the iteration.
1861
Guido van Rossum59ce9012008-08-09 14:55:34 +00001862- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1863 to _sre.compile() will now be rejected. This should not affect anybody
1864 since the re.compile() function never generates invalid re-bytecode.
1865
Skip Montanaroa032bf42008-08-08 22:52:51 +00001866- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1867 upon first access it can be automatically initialized from the csv file if
1868 it wasn't initialized during instantiation.
1869
Brett Cannon3aa2a492008-08-06 22:28:09 +00001870- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1871 the reload() built-in has been removed.
1872

Antoine Pitroude781a42008-08-09 12:43:23 +00001885 asking for a specific length. This problem only affected files opened

1942-----------------
1943
Georg Brandl3e483f62008-07-16 22:57:41 +00001944- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1945 its methods now allow for items objects that can be converted to
1946 an integer using operator.index().
1947
Mark Dickinson64b7e502008-07-16 09:40:03 +00001948- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1949 produced a ValueError instead of giving the correct float.
1950
Eric Smitha5fa5a22008-07-16 00:11:49 +00001951- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1952 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1953
Mark Dickinson7103aa42008-07-15 19:08:33 +00001954- Issue #3008: the float type has a new instance method 'float.hex'
1955 and a new class method 'float.fromhex' to convert floating-point
1956 numbers to and from hexadecimal strings, respectively.
1957
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001958- Issue #2235: __hash__ is once again inherited by default. To allow
1959 collections.Hashable to remain meaningful in the presence of the
1960 default hash implementation (object.__hash__), it is now possible
1961 to explicit block inheritance of hash by setting __hash__=None at
1962 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1963 level.
1964
Nick Coghlanb028f502008-07-13 14:52:36 +00001965- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1966 the parent module cannot be found while performing an absolute import.
1967 This means that an incorrectly defined __package__ attribute will
1968 now only prevent relative imports in that module rather than causing
1969 all imports from that module to fail.
1970
Nick Coghlan14ff9942008-07-08 14:21:42 +00001971- Issue #2517: Allow unicode messages in Exceptions again by correctly

1981 another thread's dictionary.
1982
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001983- Issue #3004: Minor change to slice.indices(): the start and stop
1984 arguments are now treated identically, making the behaviour easier
1985 to describe and understand. For example, slice(None, -10,
1986 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1987 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1988 10, -1).
1989
Georg Brandl278fc502008-07-19 12:46:12 +00001990- Issue #3219: Calling a function with repeated keyword arguments,
1991 f(a=2, a=23), would not cause a syntax error. This was a regression
1992 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001993
Georg Brandl278fc502008-07-19 12:46:12 +00001994- Issue #2862: Make int and float freelist management consistent with
1995 other freelists. Changes their CompactFreeList apis into

2003 error when they failed.
2004
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002005- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002030- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2031 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002032 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002033 content-length. The problem had been corrected in the 2.4 branch, but never
2034 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002049- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2050 handling is now the same as that of other special attributes like __name__).

Ronald Oussoren5640ce22008-06-05 12:58:24 +00002440- On MacOS X it is now possible to install the framework in 64-bit
2441 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002442 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002443
2444 This is controlled by the configure argument ``--with-universal-archs``:
2445
2446 - ``--with-universal-archs=all``: install 4-way universal
2447
2448 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2449
2450 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2451
2452 This option should be used in combination with ``--enable-universalsdk=``.
2453
2454 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

2459
Georg Brandl74a1dea2008-05-28 11:21:39 +00002460- Add ``PyType_Modified()`` as a public API to clear the type cache.
2461
2462- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00002463
2464- The PyString functions have been renamed to PyBytes. A batch of
2465 defines were added so that the linker still sees the original
2466 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002504- Issue #1631171: Re-implement the 'warnings' module in C (the
2505 original Python code has been kept as backup). This will allow for
2506 using the 'warning's machinery in such places as the parser where
2507 use of pure Python code is not possible. Both the ``showarning()``
2508 and ``formatwarning()`` gain an optional 'line' argument which is
2509 not called by default for backwards-compatibility reasons. Setting
2510 ``warnings.showwarning()`` to an implementation that lacks support
2511 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002536- The getpass module has been improved on Unix. It now uses /dev/tty
2537 by default and uses stderr instead of stdout. A GetPassWarning is
2538 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002553- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002554 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002574- Issue #2550: The approach used by client/server code for obtaining
2575 ports to listen on in network-oriented tests has been refined in an
2576 effort to facilitate running multiple instances of the entire
2577 regression test suite in parallel without issue.
2578 test_support.bind_port() has been fixed such that it will always
2579 return a unique port -- which wasn't always the case with the
2580 previous implementation, especially if socket options had been set
2581 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2582 new implementation of bind_port() will actually raise an exception
2583 if it is passed an AF_INET/SOCK_STREAM socket with either the
2584 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2585 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2586 the socket it's been passed. This currently only applies to
2587 Windows. This option prevents any other sockets from binding to the
2588 host/port we've bound to, thus removing the possibility of the
2589 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2590 when a second SOCK_STREAM socket binds and accepts to a host/port
2591 that's already been bound by another socket. The optional preferred
2592 port parameter to bind_port() has been removed. Under no
2593 circumstances should tests be hard coding ports!
2594
2595 test_support.find_unused_port() has also been introduced, which will
2596 pass a temporary socket object to bind_port() in order to obtain an
2597 unused port. The temporary socket object is then closed and
2598 deleted, and the port is returned. This method should only be used
2599 for obtaining an unused port in order to pass to an external program
2600 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2601 a parameter to a server-oriented class that doesn't give you direct
2602 access to the underlying socket used.
2603
2604 Finally, test_support.HOST has been introduced, which should be used
2605 for the host argument of any relevant socket calls (i.e. bind and
2606 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002607
2608 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002609 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002610 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2611 test_asynchat and test_socket_ssl.
2612
Georg Brandl3ee81df2008-05-17 18:14:43 +00002613 It is now possible for multiple instances of the regression test
2614 suite to run in parallel without issue.

2882
Fred Drakea8ee94b2008-03-01 02:45:07 +00002883- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002884 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002889
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002890- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002891 issue 215555 for a discussion.
2892
Eric Smitha73fbe72008-02-23 03:09:44 +00002893- Added the future_builtins module, which contains hex() and oct().
2894 These are the PEP 3127 version of these functions, designed to be
2895 compatible with the hex() and oct() builtins from Python 3.0. They
2896 differ slightly in their output formats from the existing, unchanged
2897 Python 2.6 builtins. The expected usage of the future_builtins
2898 module is:
2899 from future_builtins import hex, oct
2900
Eric Smith7ef40bf2008-02-20 23:34:22 +00002901- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2902 exponents for exponents with absolute value < 100. Follows C99
2903 standard. This is a change on Windows, which would use 3 digits.
2904 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2905 so that any alterations it does to the resulting string will be
2906 available in stringlib/formatter.h (for float.__format__).
2907
Eric Smith5a3c1352008-02-19 13:21:56 +00002908- Implemented PEP 3101, Advanced String Formatting. This adds a new
2909 builtin format(); a format() method for str and unicode; a
2910 __format__() method to object, str, unicode, int, long, float, and
2911 datetime; the class string.Formatter; and the C API
2912 PyObject_Format().
2913
Georg Brandl3ee81df2008-05-17 18:14:43 +00002914- Fixed several potential crashes, all caused by specially crafted
2915 __del__ methods exploiting objects in temporarily inconsistent
2916 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002917
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002918- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002919 prevent a possible crash: an Abstract Base Class would try to access
2920 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002925- Clear all free lists during a gc.collect() of the highest generation
2926 in order to allow pymalloc to free more arenas. Python may give back
2927 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002928
Georg Brandl3ee81df2008-05-17 18:14:43 +00002929- Issue #2045: Fix an infinite recursion triggered when printing a
2930 subclass of collections.defaultdict, if its default_factory is set
2931 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002932
Christian Heimesf75dbef2008-02-08 00:11:31 +00002933- Fixed a minor memory leak in dictobject.c. The content of the free
2934 list was not freed on interpreter shutdown.
2935
Georg Brandl5a7eca12010-03-21 19:29:04 +00002936- Limit free list of method and built-in function objects to 256

2940 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002941 to compact the internal free lists of pre-allocted ints and floats.
2942
Georg Brandl3ee81df2008-05-17 18:14:43 +00002943- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2944 calls. Python expected the return type int but the fork familie
2945 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002946

2957 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002958
Georg Brandl3ee81df2008-05-17 18:14:43 +00002959- Patch #1473257: generator objects gain a gi_code attribute. This is
2960 the same object as the func_code attribute of the function that
2961 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002962
Georg Brandl3ee81df2008-05-17 18:14:43 +00002963- Issue #1920: "while 0" statements were completely removed by the
2964 compiler, even in the presence of an "else" clause, which is
2965 supposed to be run when the condition is false. Now the compiler
2966 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002967
Guido van Rossumeead05f2008-01-24 18:21:02 +00002968- A few crashers fixed: weakref_in_del.py (issue #1377858);
2969 loosing_dict_ref.py (issue #1303614, test67.py);
2970 borrowed_ref_[34].py (not in tracker).
2971
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002972- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002973 suppressed while an extension is loaded by calling SetErrorMode in
2974 dynload_win.c. The error is still reported properly.
2975
Georg Brandl3ee81df2008-05-17 18:14:43 +00002976- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002977 several extension methods and modules do not work without unicode
2978 support.
2979
Georg Brandl26543b12008-01-21 18:36:51 +00002980- Issue #1882: when compiling code from a string, encoding cookies in the
2981 second line of code were not always recognized correctly.
2982
Georg Brandl14404b62008-01-19 19:27:05 +00002983- Issue #1679: "0x" was taken as a valid integer literal.
2984
Georg Brandl6caad7d2008-01-26 14:19:22 +00002985- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002986 added.
2987
Christian Heimesc94e2b52008-01-14 04:13:37 +00002988- sys.float_info / PyFloat_GetInfo: The floating point information
2989 object was converted from a dict to a specialized structseq object.
2990
Georg Brandl3ee81df2008-05-17 18:14:43 +00002991- Patch #1816: Added sys.flags structseq. It exposes the status of
2992 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002993
Georg Brandl3ee81df2008-05-17 18:14:43 +00002994- Objects/structseq.c: Implemented new structseq representation. The
2995 patch makes structseqs (e.g. the return value of os.stat) more
2996 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002997
Georg Brandl3ee81df2008-05-17 18:14:43 +00002998- Patch #1700288: added a type attribute cache that caches method
2999 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003000
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003001- Bug #1776: __import__() no longer accepts filenames on any platform.
3002 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003003
Georg Brandlaed6c662008-01-07 17:25:53 +00003004- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3005
Georg Brandl3ee81df2008-05-17 18:14:43 +00003006- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3007 envvar and sys.dont_write_bytecode attribute. All these can be set
3008 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003009
Georg Brandl3ee81df2008-05-17 18:14:43 +00003010- Improve some exception messages when Windows fails to load an
3011 extension module. Now we get for example '%1 is not a valid Win32
3012 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003013
Georg Brandl3ee81df2008-05-17 18:14:43 +00003014- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003016- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3017 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003018
Christian Heimes0a8143f2007-12-18 23:22:54 +00003019- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003020 and INF. float("nan"), float("inf") and float("-inf") now work on
3021 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003022
Georg Brandl3ee81df2008-05-17 18:14:43 +00003023- Compiler now generates simpler and faster code for dictionary
3024 literals. The oparg for BUILD_MAP now indicates an estimated
3025 dictionary size. There is a new opcode, STORE_MAP, for adding
3026 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003027
Georg Brandl3ee81df2008-05-17 18:14:43 +00003028- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00003029
Georg Brandl3ee81df2008-05-17 18:14:43 +00003030- Issue #1620: New property decorator syntax was modifying the
3031 decorator in place instead of creating a new decorator object.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003033- Issue #1538: Avoid copying string in split/rsplit if the split char
3034 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00003035
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003036- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003037 SystemError.
3038
Nick Coghlanef01d822007-12-03 12:55:17 +00003039- PEP 366: Allow explicit relative imports when executing modules
3040 inside packages with the -m switch via a new module level
3041 __package__ attribute.
3042
Georg Brandl3ee81df2008-05-17 18:14:43 +00003043- Issue #1402: Fix a crash on exit, when another thread is still
3044 running, and if the deallocation of its frames somehow calls the
3045 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003046

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00003050 attribute of an empty cell object.
3051
Georg Brandl3ee81df2008-05-17 18:14:43 +00003052- Issue #1460: The utf-7 incremental decoder did not accept truncated
3053 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00003054
Georg Brandl3ee81df2008-05-17 18:14:43 +00003055- Patch #1739468: Directories and zipfiles containing a __main__.py
3056 file can now be directly executed by passing their name to the
3057 interpreter. The directory/zipfile is automatically inserted as the
3058 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003059
Georg Brandl3ee81df2008-05-17 18:14:43 +00003060- Issue #1265: Fix a problem with sys.settrace, if the tracing
3061 function uses a generator expression when at the same time the
3062 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003063
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003064- sets and frozensets now have an isdisjoint() method.
3065
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003066- optimize the performance of builtin.sum().
3067
Neal Norwitz44f326e2007-10-05 05:29:17 +00003068- Fix warnings found by the new version of the Coverity checker.
3069
Georg Brandl5a7eca12010-03-21 19:29:04 +00003070- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003071 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3072 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003073
Georg Brandl3ee81df2008-05-17 18:14:43 +00003074- Issue #1686386: Tuple's tp_repr did not take into account the
3075 possibility of having a self-referential tuple, which is possible
3076 from C code. Nor did object's tp_str consider that a type's tp_str
3077 could do something that could lead to an inifinite recursion.
3078 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3079 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003080
Georg Brandl3ee81df2008-05-17 18:14:43 +00003081- Issue #1164: It was possible to trigger deadlock when using the
3082 'print' statement to write to a file since the GIL was not released
3083 as needed. Now PyObject_Print() does the right thing along with
3084 various tp_print implementations of the built-in types and those in
3085 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003086
Georg Brandl3ee81df2008-05-17 18:14:43 +00003087- Issue #1147: Exceptions were directly allowing string exceptions in
3088 their throw() method even though string exceptions no longer
3089 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003090
Georg Brandl3ee81df2008-05-17 18:14:43 +00003091- Issue #1096: Prevent a segfault from getting the repr of a very
3092 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003093
Brett Cannon1e534b52007-09-07 04:18:30 +00003094- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003095 PyObject_Call() never calling back out to Python code to trigger
3096 recursion depth updates/checks. Required the creation of a static
3097 RuntimeError instance in case normalizing an exception put the
3098 recursion check value past its limit. Fixes crashers
3099 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003100
Georg Brandl3ee81df2008-05-17 18:14:43 +00003101- Patch #1031213: Decode source line in SyntaxErrors back to its

3105 with %G.
3106
Georg Brandl3ee81df2008-05-17 18:14:43 +00003107- Prevent expandtabs() on string and unicode objects from causing a
3108 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00003109

Neal Norwitz0ac60192007-05-27 04:08:54 +00003114- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003115 __*__ attributes. (Some already existed, e.g., __doc__ and
3116 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003117
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003118- Add -3 option to the interpreter to warn about features that are
3119 deprecated and will be changed/removed in Python 3.0.
3120
Georg Brandl2134e752007-05-21 20:34:16 +00003121- Patch #1686487: you can now pass any mapping after '**' in function
3122 calls.
3123
Collin Winter62903052007-05-18 23:11:24 +00003124- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003125 "except E as target:". This is to provide forwards compatibility
3126 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003127
Brett Cannon229cee22007-05-05 01:34:02 +00003128- Deprecate BaseException.message as per PEP 352.
3129
Georg Brandl3ee81df2008-05-17 18:14:43 +00003130- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003131 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003132
Vinay Sajip8549ce32007-05-06 17:53:37 +00003133- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003134 setting a plain string, ie don't expand to single letter identifiers.
3135
Raymond Hettinger13936692007-04-11 18:40:58 +00003136- Request #1191699: Slices can now be pickled.
3137
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003138- Request #1193128: str.translate() now allows a None argument for
3139 translations that only remove characters without re-mapping the
3140 remaining characters.
3141
Georg Brandl5cb76c12007-03-21 09:00:39 +00003142- Patch #1682205: a TypeError while unpacking an iterable is no longer
3143 masked by a generic one with the message "unpack non-sequence".
3144
Neal Norwitzaa754b72007-03-21 06:39:48 +00003145- Remove unused file Python/fmod.c.
3146
Guido van Rossum143b5642007-03-23 04:58:42 +00003147- Bug #1683368: The object.__init__() and object.__new__() methods are
3148 now stricter in rejecting excess arguments. The only time when
3149 either allows excess arguments is when it is not overridden and the
3150 other one is. For backwards compatibility, when both are
3151 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003152 warning later). Also, type.__init__() insists on the same signature
3153 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003154
Georg Brandl3ee81df2008-05-17 18:14:43 +00003155- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3156 object to complex using its __complex__() method before falling back
3157 to the __float__() method. Therefore, the functions in the cmath
3158 module now can operate on objects that define a __complex__()
3159 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003160
Georg Brandl3ee81df2008-05-17 18:14:43 +00003161- Patch #1623563: allow __class__ assignment for classes with
3162 __slots__. The old and the new class are still required to have the
3163 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003164
Georg Brandl3ee81df2008-05-17 18:14:43 +00003165- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00003168- Patch #1462488: Python no longer segfaults when
3169 ``object.__reduce_ex__()`` is called with an object that is faking
3170 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003171
Georg Brandl3ee81df2008-05-17 18:14:43 +00003172- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00003175- Patch #1444529: the builtin compile() now accepts keyword arguments.
3176
Georg Brandl7b9c5552007-03-12 14:30:05 +00003177- Bug #1678647: write a newline after printing an exception in any
3178 case, even when converting the value to a string failed.
3179
Georg Brandl871f1bc2007-03-12 13:17:36 +00003180- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003181 its argument, if it exists. If not, it will work like before. This
3182 allows customizing the output of dir() in the presence of a
3183 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003184
Collin Winter276887b2007-03-12 16:11:39 +00003185- Patch #922167: Python no longer segfaults when faced with infinitely
3186 self-recursive reload() calls (as reported by bug #742342).
3187
Georg Brandl3ee81df2008-05-17 18:14:43 +00003188- Patch #1675981: remove unreachable code from ``type.__new__()``
3189 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00003190
Georg Brandl3ee81df2008-05-17 18:14:43 +00003191- Patch #1491866: change the complex() constructor to allow
3192 parthensized forms. This means complex(repr(x)) now works instead of
3193 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003194
Georg Brandlaa2321b2007-03-07 00:40:28 +00003195- Patch #703779: unset __file__ in __main__ after running a file. This

3704 ".cpp" too.
3705
Facundo Batistad918a652007-04-24 13:54:38 +00003706- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003707 the client's request was successfully received, understood, and
3708 accepted. Now in these cases no error is raised in urllib (issue
3709 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00003710

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00003717- Added a timeout parameter to the constructor of other protocols
3718 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3719 work started with create_connection() and timeout in httplib, and
3720 closes patch #723312.
3721
Vinay Sajip8549ce32007-05-06 17:53:37 +00003722- Patch #1676823: Added create_connection() to socket.py, which may be
3723 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00003724 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00003725
Martin v. Löwis0af33882007-03-23 13:27:15 +00003726- Bug #978833: Revert r50844, as it broke _socketobject.dup.

3746
Georg Brandlf66b6032007-03-14 08:27:52 +00003747- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00003748 AttributeError instead of an IOError when the server's response
3749 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003750
Georg Brandl3ee81df2008-05-17 18:14:43 +00003751- Patch #957650: "%var%" environment variable references are now
3752 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl03b90d82007-03-13 22:07:36 +00003754
Georg Brandl3ee81df2008-05-17 18:14:43 +00003755- Patch #1429539: pdb now correctly initializes the __main__ module
3756 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003757 correctly now.
3758
Georg Brandlbad6f192007-03-13 21:32:56 +00003759- The nonobvious commands.getstatus() function is now deprecated.

3765
Georg Brandl3ee81df2008-05-17 18:14:43 +00003766- Patch #1530482: add pydoc.render_doc() which returns the
3767 documentation for a thing instead of paging it to stdout, which
3768 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00003769
Georg Brandl3ee81df2008-05-17 18:14:43 +00003770- Patch #1533909: the timeit module now accepts callables in addition

3776 parameter which can be set to False to prevent the default
3777 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00003779- Patch #1581073: add a flag to textwrap that prevents the dropping of
3780 whitespace while wrapping.
3781
Georg Brandl92a6bae2007-03-13 17:43:32 +00003782- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003783 are set for invalid interpolation sequences that would lead to
3784 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00003785

3798
Georg Brandl94fe3f52007-03-13 09:32:11 +00003799- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00003800 field names in its exception message if you try to write a record
3801 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00003819

3827 returned string up to the first NUL character.

3838
Georg Brandl3ee81df2008-05-17 18:14:43 +00003839- unittest now verifies more of its assumptions. In particular,
3840 TestCase and TestSuite subclasses (not instances) are no longer
3841 accepted in TestSuite.addTest(). This should cause no
3842 incompatibility since it never made sense with ordinary subclasses
3843 -- the failure just occurred later, with a more cumbersome
3844 exception.

3853 given a unicode argument and os.listdir() returns unicode filenames.
3854
Georg Brandl3ee81df2008-05-17 18:14:43 +00003855- Patch #1673619: setup.py identifies extension modules it doesn't

3857 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004233 time so that opening a database previously created with the DB_DUP
4234 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4235 opens. Specifically: dictionary assignment to a DB object will
4236 replace all values for a given key when the database allows
4237 duplicate values. DB users should use DB.put(k, v) when they want
4238 to store duplicates; not DB[k] = v.

4245 characters with ASCII value less than 32. Also, it correctly quotes
4246 dots only if they occur on a single line, as opposed to the previous
4247 behavior of quoting dots if they are the second character of any
4248 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004249
