1006
Benjamin Petersonc6e80eb2008-12-21 17:01:26 +00001007- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

1013
Vinay Sajip6badbe92009-01-20 22:49:13 +00001014- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Georg Brandld2094602008-12-05 08:51:30 +00001015 method on file objects with closefd=False. The file descriptor is still
1016 kept open but the file object behaves like a closed file. The ``FileIO``
1017 object also got a new readonly attribute ``closefd``.
1018
Georg Brandlfa71a902008-12-05 09:08:28 +00001019- Issue #3689: The list reversed iterator now supports __length_hint__

Jesse Nollerb48cfa62009-03-30 16:19:10 +00001087 socket.SO_REUSEADDR on all connections so that the user no longer needs

1225 zipimport (or any other conformant PEP 302 loader). Original patch by

1227
1228- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
1229 302 conformant loader) will now work correctly in most cases (they
1230 are still subject to the constraints that exist for all code running
1231 from inside a module loaded via a PEP 302 loader and attempting to

1390What's New in Python 2.6.1
1391==========================
1392
1393*Release date: 04-Dec-2008*
1394
1395Core and Builtins
1396-----------------
1397
1398- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1399 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1400 instead of throwing a MemoryError.
1401
1402- Issue #4367: Python would segfault during compiling when the unicodedata
1403 module couldn't be imported and \N escapes were present.
1404
1405- Issue #4348: Some bytearray methods returned that didn't cause any change to
1406 the bytearray, returned the same bytearray instead of a copy.
1407
1408- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1409
1410- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1411
1412- Issue #4048: The parser module now correctly validates relative imports.
1413
1414- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

1417- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1418 method does not return iterators for the 4th and 5th items.
1419
1420- Issue #4209: Enabling unicode_literals and the print_function in the same
1421 __future__ import didn't work.
1422
1423- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1424 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1425 really executed because I cannot move to such directory on win2k)
1426
1427- Issue #4069: When set.remove(element) is used with a set element, the element
1428 is temporarily replaced with an equivalent frozenset. But the eventual
1429 KeyError would always report the empty frozenset([]) as the missing key. Now
1430 it correctly refers to the initial element.
1431
1432- Fixed C99 style comments in several files. Python is now C89 compatible
1433 again.

Vinay Sajip35e3b032008-09-01 14:33:59 +00001607- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001608 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1609 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1610 when given a tuple of classes as second argument, were looking up
1611 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1612 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001748What's New in Python 2.6 beta 3?
1749================================
1750
Barry Warsaw07a4a382008-08-21 01:15:08 +00001751*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001752
1753Core and Builtins
1754-----------------
1755
Guido van Rossumf8402962008-08-20 15:01:50 +00001756- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1757 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1758 extensions do not automatically benefit from the class attribute
1759 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1760 to their tp_flags field if they care. This is a backwards
1761 compatibility feature; in 3.0, all types will use the cache by
1762 default.
1763
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001764- Keyword arguments can now follow starred arguments. (``f(a, *args,
1765 keyword=23)`` is now valid syntax.)
1766
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001767- ctypes function pointers that are COM methods have a boolean True
1768 value again.
1769
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001770- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1771 by denying s# to parse objects that have a releasebuffer procedure,
1772 and introducing s*.
1773
Georg Brandl1e13ea92008-08-11 09:07:59 +00001774- Issue #3537: Fix an assertion failure when an empty but presized dict
1775 object was stored in the freelist.
1776
Mark Dickinsonb6467572008-08-04 21:30:09 +00001777- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1778 ValueError consistently across platforms.
1779
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001780- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1781 (64bit Unix, for example), unichr() would truncate its argument and return
1782 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1783
Neal Norwitze7d8be82008-07-31 17:17:14 +00001784- Apply security patches from Apple.
1785
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001786- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1787 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1788
Antoine Pitrou92f82162008-07-25 22:22:08 +00001789- Issue #1819: function calls with several named parameters are now on
1790 average 35% faster (as measured by pybench).
1791
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001792- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1793 the python debugger steps into a class statement: the free variables (local
1794 variables defined in an outer scope) would be deleted from the outer scope.
1795
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001796- Issue #2620: Overflow checking when allocating or reallocating memory
1797 was not always being done properly in some python types and extension
1798 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1799 all been updated to perform better checks and places in the code that
1800 would previously leak memory on the error path when such an allocation
1801 failed have been fixed.

1804-------
1805
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001806- Issue #3612: Added some missing basic types in ctypes.wintypes.
1807
Benjamin Petersone977ad42008-08-20 01:42:01 +00001808- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1809 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1810
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001811- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1812 version reported by these tools does not necessarily follow the python
1813 version numbering scheme, so the module is less strict when parsing it.
1814
Nick Coghlanf70385a2008-08-18 12:42:46 +00001815- Issue #2235: Added Py3k warnings for types which will become unhashable
1816 under the stricter __hash__ inheritance rules in 3.0. Several types
1817 which did not meet the rules for hash invariants and were already
1818 unhashable in 3.0 have now been explicitly flagged as unhashable in
1819 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1820 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1821
Brett Cannon88f801d2008-08-18 00:46:22 +00001822- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1823 imported into the module but exposed as part of the module's API.
1824
Brett Cannon7b96f072008-08-18 00:41:11 +00001825- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1826
Brett Cannon46225e72008-08-18 00:36:52 +00001827- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1828
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001829- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1830
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001831- Issue #3575: Incremental decoder's decode function now takes bytearray
1832 by using 's*' instead of 't#'.
1833
Jesus Cea585ad8a2009-07-02 15:37:21 +00001834- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001835 fails unicode conversion on 2nd parameter. (windows only)
1836
Facundo Batista94f243a2008-08-17 03:38:39 +00001837- Issue 2464. urllib2 now supports a malformation in the URL received
1838 in a redirect.
1839
Brett Cannonabe423e2008-08-16 21:47:07 +00001840- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001841 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001842
Facundo Batistaeb90b782008-08-16 14:44:07 +00001843- Issue #2776: fixed small issue when handling an URL with double slash
1844 after a 302 response in the case of not going through a proxy.
1845
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001846- Issue #2676: in the email package, content-type parsing was hanging on
1847 pathological input because of quadratic or exponential behaviour of a
1848 regular expression.
1849
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001850- Issue #3476: binary buffered reading through the new "io" library is now
1851 thread-safe.
1852
Brett Cannonbf3157b2008-08-14 05:00:03 +00001853- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1854 since mimetools itself is deprecated. Because modules are cached, all
1855 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1856
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001857- Issue #3134: shutil referenced undefined WindowsError symbol.
1858
Robert Schuppenies14646332008-08-10 11:01:53 +00001859- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1860 menu entries were not deleted.
1861
Brett Cannon83e81842008-08-09 23:30:55 +00001862- Copied the implementation of reduce() to _functools.reduce() to have a
1863 version that did not raise a DeprecationWarning under -3.
1864
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001865- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1866 a MemoryError rather than silently stop the iteration.
1867
Guido van Rossum59ce9012008-08-09 14:55:34 +00001868- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1869 to _sre.compile() will now be rejected. This should not affect anybody
1870 since the re.compile() function never generates invalid re-bytecode.
1871
Skip Montanaroa032bf42008-08-08 22:52:51 +00001872- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1873 upon first access it can be automatically initialized from the csv file if
1874 it wasn't initialized during instantiation.
1875
Brett Cannon3aa2a492008-08-06 22:28:09 +00001876- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1877 the reload() built-in has been removed.
1878

Antoine Pitroude781a42008-08-09 12:43:23 +00001891 asking for a specific length. This problem only affected files opened
1892 using the new "io" module, not the built-in open() function.

1919 mode 0600 rather than 000 under Unix.
1920
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001921- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

1944
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001945*Release date: 17-Jul-2008*

1948-----------------
1949
Georg Brandl3e483f62008-07-16 22:57:41 +00001950- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1951 its methods now allow for items objects that can be converted to
1952 an integer using operator.index().
1953
Mark Dickinson64b7e502008-07-16 09:40:03 +00001954- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1955 produced a ValueError instead of giving the correct float.
1956
Eric Smitha5fa5a22008-07-16 00:11:49 +00001957- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1958 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1959
Mark Dickinson7103aa42008-07-15 19:08:33 +00001960- Issue #3008: the float type has a new instance method 'float.hex'
1961 and a new class method 'float.fromhex' to convert floating-point
1962 numbers to and from hexadecimal strings, respectively.
1963
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001964- Issue #2235: __hash__ is once again inherited by default. To allow
1965 collections.Hashable to remain meaningful in the presence of the
1966 default hash implementation (object.__hash__), it is now possible
1967 to explicit block inheritance of hash by setting __hash__=None at
1968 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1969 level.
1970
Nick Coghlanb028f502008-07-13 14:52:36 +00001971- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1972 the parent module cannot be found while performing an absolute import.
1973 This means that an incorrectly defined __package__ attribute will
1974 now only prevent relative imports in that module rather than causing
1975 all imports from that module to fail.
1976
Nick Coghlan14ff9942008-07-08 14:21:42 +00001977- Issue #2517: Allow unicode messages in Exceptions again by correctly

1986 threading.local: the first member set by a thread could be saved in
1987 another thread's dictionary.
1988
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001989- Issue #3004: Minor change to slice.indices(): the start and stop
1990 arguments are now treated identically, making the behaviour easier
1991 to describe and understand. For example, slice(None, -10,
1992 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1993 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1994 10, -1).
1995
Georg Brandl278fc502008-07-19 12:46:12 +00001996- Issue #3219: Calling a function with repeated keyword arguments,
1997 f(a=2, a=23), would not cause a syntax error. This was a regression
1998 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001999
Georg Brandl278fc502008-07-19 12:46:12 +00002000- Issue #2862: Make int and float freelist management consistent with
2001 other freelists. Changes their CompactFreeList apis into

2009 error when they failed.
2010
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002011- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002036- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2037 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002038 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002039 content-length. The problem had been corrected in the 2.4 branch, but never
2040 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002055- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2056 handling is now the same as that of other special attributes like __name__).

Ronald Oussoren5640ce22008-06-05 12:58:24 +00002446- On MacOS X it is now possible to install the framework in 64-bit
2447 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002448 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002449
2450 This is controlled by the configure argument ``--with-universal-archs``:
2451
2452 - ``--with-universal-archs=all``: install 4-way universal
2453
2454 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2455
2456 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2457
2458 This option should be used in combination with ``--enable-universalsdk=``.
2459
2460 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

2465
Georg Brandl74a1dea2008-05-28 11:21:39 +00002466- Add ``PyType_Modified()`` as a public API to clear the type cache.
2467
2468- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00002469
2470- The PyString functions have been renamed to PyBytes. A batch of
2471 defines were added so that the linker still sees the original
2472 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002510- Issue #1631171: Re-implement the 'warnings' module in C (the
2511 original Python code has been kept as backup). This will allow for
2512 using the 'warning's machinery in such places as the parser where
2513 use of pure Python code is not possible. Both the ``showarning()``
2514 and ``formatwarning()`` gain an optional 'line' argument which is
2515 not called by default for backwards-compatibility reasons. Setting
2516 ``warnings.showwarning()`` to an implementation that lacks support
2517 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002542- The getpass module has been improved on Unix. It now uses /dev/tty
2543 by default and uses stderr instead of stdout. A GetPassWarning is
2544 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002559- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002560 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002580- Issue #2550: The approach used by client/server code for obtaining
2581 ports to listen on in network-oriented tests has been refined in an
2582 effort to facilitate running multiple instances of the entire
2583 regression test suite in parallel without issue.
2584 test_support.bind_port() has been fixed such that it will always
2585 return a unique port -- which wasn't always the case with the
2586 previous implementation, especially if socket options had been set
2587 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2588 new implementation of bind_port() will actually raise an exception
2589 if it is passed an AF_INET/SOCK_STREAM socket with either the
2590 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2591 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2592 the socket it's been passed. This currently only applies to
2593 Windows. This option prevents any other sockets from binding to the
2594 host/port we've bound to, thus removing the possibility of the
2595 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2596 when a second SOCK_STREAM socket binds and accepts to a host/port
2597 that's already been bound by another socket. The optional preferred
2598 port parameter to bind_port() has been removed. Under no
2599 circumstances should tests be hard coding ports!
2600
2601 test_support.find_unused_port() has also been introduced, which will
2602 pass a temporary socket object to bind_port() in order to obtain an
2603 unused port. The temporary socket object is then closed and
2604 deleted, and the port is returned. This method should only be used
2605 for obtaining an unused port in order to pass to an external program
2606 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2607 a parameter to a server-oriented class that doesn't give you direct
2608 access to the underlying socket used.
2609
2610 Finally, test_support.HOST has been introduced, which should be used
2611 for the host argument of any relevant socket calls (i.e. bind and
2612 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002613
2614 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002615 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002616 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2617 test_asynchat and test_socket_ssl.
2618
Georg Brandl3ee81df2008-05-17 18:14:43 +00002619 It is now possible for multiple instances of the regression test
2620 suite to run in parallel without issue.

2887-----------------
2888
Fred Drakea8ee94b2008-03-01 02:45:07 +00002889- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002890 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002895
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002896- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002897 issue 215555 for a discussion.
2898
Eric Smitha73fbe72008-02-23 03:09:44 +00002899- Added the future_builtins module, which contains hex() and oct().
2900 These are the PEP 3127 version of these functions, designed to be
2901 compatible with the hex() and oct() builtins from Python 3.0. They
2902 differ slightly in their output formats from the existing, unchanged
2903 Python 2.6 builtins. The expected usage of the future_builtins
2904 module is:
2905 from future_builtins import hex, oct
2906
Eric Smith7ef40bf2008-02-20 23:34:22 +00002907- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2908 exponents for exponents with absolute value < 100. Follows C99
2909 standard. This is a change on Windows, which would use 3 digits.
2910 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2911 so that any alterations it does to the resulting string will be
2912 available in stringlib/formatter.h (for float.__format__).
2913
Eric Smith5a3c1352008-02-19 13:21:56 +00002914- Implemented PEP 3101, Advanced String Formatting. This adds a new
2915 builtin format(); a format() method for str and unicode; a
2916 __format__() method to object, str, unicode, int, long, float, and
2917 datetime; the class string.Formatter; and the C API
2918 PyObject_Format().
2919
Georg Brandl3ee81df2008-05-17 18:14:43 +00002920- Fixed several potential crashes, all caused by specially crafted
2921 __del__ methods exploiting objects in temporarily inconsistent
2922 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002923
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002924- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002925 prevent a possible crash: an Abstract Base Class would try to access
2926 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002927

Georg Brandl3ee81df2008-05-17 18:14:43 +00002931- Clear all free lists during a gc.collect() of the highest generation
2932 in order to allow pymalloc to free more arenas. Python may give back
2933 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002934
Georg Brandl3ee81df2008-05-17 18:14:43 +00002935- Issue #2045: Fix an infinite recursion triggered when printing a
2936 subclass of collections.defaultdict, if its default_factory is set
2937 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002938
Christian Heimesf75dbef2008-02-08 00:11:31 +00002939- Fixed a minor memory leak in dictobject.c. The content of the free
2940 list was not freed on interpreter shutdown.
2941
Georg Brandl5a7eca12010-03-21 19:29:04 +00002942- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00002943 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002944

2946 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002947 to compact the internal free lists of pre-allocted ints and floats.
2948
Georg Brandl3ee81df2008-05-17 18:14:43 +00002949- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2950 calls. Python expected the return type int but the fork familie
2951 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002952

2963 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002964
Georg Brandl3ee81df2008-05-17 18:14:43 +00002965- Patch #1473257: generator objects gain a gi_code attribute. This is
2966 the same object as the func_code attribute of the function that
2967 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002968
Georg Brandl3ee81df2008-05-17 18:14:43 +00002969- Issue #1920: "while 0" statements were completely removed by the
2970 compiler, even in the presence of an "else" clause, which is
2971 supposed to be run when the condition is false. Now the compiler
2972 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002973
Guido van Rossumeead05f2008-01-24 18:21:02 +00002974- A few crashers fixed: weakref_in_del.py (issue #1377858);
2975 loosing_dict_ref.py (issue #1303614, test67.py);
2976 borrowed_ref_[34].py (not in tracker).
2977
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002978- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002979 suppressed while an extension is loaded by calling SetErrorMode in
2980 dynload_win.c. The error is still reported properly.
2981
Georg Brandl3ee81df2008-05-17 18:14:43 +00002982- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002983 several extension methods and modules do not work without unicode
2984 support.
2985
Georg Brandl26543b12008-01-21 18:36:51 +00002986- Issue #1882: when compiling code from a string, encoding cookies in the
2987 second line of code were not always recognized correctly.
2988
Georg Brandl14404b62008-01-19 19:27:05 +00002989- Issue #1679: "0x" was taken as a valid integer literal.
2990
Georg Brandl6caad7d2008-01-26 14:19:22 +00002991- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002992 added.
2993
Christian Heimesc94e2b52008-01-14 04:13:37 +00002994- sys.float_info / PyFloat_GetInfo: The floating point information
2995 object was converted from a dict to a specialized structseq object.
2996
Georg Brandl3ee81df2008-05-17 18:14:43 +00002997- Patch #1816: Added sys.flags structseq. It exposes the status of
2998 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002999
Georg Brandl3ee81df2008-05-17 18:14:43 +00003000- Objects/structseq.c: Implemented new structseq representation. The
3001 patch makes structseqs (e.g. the return value of os.stat) more
3002 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003003
Georg Brandl3ee81df2008-05-17 18:14:43 +00003004- Patch #1700288: added a type attribute cache that caches method
3005 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003006
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003007- Bug #1776: __import__() no longer accepts filenames on any platform.
3008 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003009
Georg Brandlaed6c662008-01-07 17:25:53 +00003010- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3011
Georg Brandl3ee81df2008-05-17 18:14:43 +00003012- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3013 envvar and sys.dont_write_bytecode attribute. All these can be set
3014 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003015
Georg Brandl3ee81df2008-05-17 18:14:43 +00003016- Improve some exception messages when Windows fails to load an
3017 extension module. Now we get for example '%1 is not a valid Win32
3018 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003019
Georg Brandl3ee81df2008-05-17 18:14:43 +00003020- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003022- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3023 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003024
Christian Heimes0a8143f2007-12-18 23:22:54 +00003025- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003026 and INF. float("nan"), float("inf") and float("-inf") now work on
3027 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003028
Georg Brandl3ee81df2008-05-17 18:14:43 +00003029- Compiler now generates simpler and faster code for dictionary
3030 literals. The oparg for BUILD_MAP now indicates an estimated
3031 dictionary size. There is a new opcode, STORE_MAP, for adding
3032 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003033
Georg Brandl3ee81df2008-05-17 18:14:43 +00003034- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003036- Issue #1620: New property decorator syntax was modifying the
3037 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00003038
Georg Brandl3ee81df2008-05-17 18:14:43 +00003039- Issue #1538: Avoid copying string in split/rsplit if the split char
3040 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00003041
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003042- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003043 SystemError.
3044
Nick Coghlanef01d822007-12-03 12:55:17 +00003045- PEP 366: Allow explicit relative imports when executing modules
3046 inside packages with the -m switch via a new module level
3047 __package__ attribute.
3048
Georg Brandl3ee81df2008-05-17 18:14:43 +00003049- Issue #1402: Fix a crash on exit, when another thread is still
3050 running, and if the deallocation of its frames somehow calls the
3051 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003052

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00003056 attribute of an empty cell object.
3057
Georg Brandl3ee81df2008-05-17 18:14:43 +00003058- Issue #1460: The utf-7 incremental decoder did not accept truncated
3059 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00003060
Georg Brandl3ee81df2008-05-17 18:14:43 +00003061- Patch #1739468: Directories and zipfiles containing a __main__.py
3062 file can now be directly executed by passing their name to the
3063 interpreter. The directory/zipfile is automatically inserted as the
3064 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003065
Georg Brandl3ee81df2008-05-17 18:14:43 +00003066- Issue #1265: Fix a problem with sys.settrace, if the tracing
3067 function uses a generator expression when at the same time the
3068 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003069
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003070- sets and frozensets now have an isdisjoint() method.
3071
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003072- optimize the performance of builtin.sum().
3073
Neal Norwitz44f326e2007-10-05 05:29:17 +00003074- Fix warnings found by the new version of the Coverity checker.
3075
Georg Brandl5a7eca12010-03-21 19:29:04 +00003076- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003077 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3078 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003079
Georg Brandl3ee81df2008-05-17 18:14:43 +00003080- Issue #1686386: Tuple's tp_repr did not take into account the
3081 possibility of having a self-referential tuple, which is possible
3082 from C code. Nor did object's tp_str consider that a type's tp_str
3083 could do something that could lead to an inifinite recursion.
3084 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3085 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003086
Georg Brandl3ee81df2008-05-17 18:14:43 +00003087- Issue #1164: It was possible to trigger deadlock when using the
3088 'print' statement to write to a file since the GIL was not released
3089 as needed. Now PyObject_Print() does the right thing along with
3090 various tp_print implementations of the built-in types and those in
3091 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003092
Georg Brandl3ee81df2008-05-17 18:14:43 +00003093- Issue #1147: Exceptions were directly allowing string exceptions in
3094 their throw() method even though string exceptions no longer
3095 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003096
Georg Brandl3ee81df2008-05-17 18:14:43 +00003097- Issue #1096: Prevent a segfault from getting the repr of a very
3098 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003099
Brett Cannon1e534b52007-09-07 04:18:30 +00003100- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003101 PyObject_Call() never calling back out to Python code to trigger
3102 recursion depth updates/checks. Required the creation of a static
3103 RuntimeError instance in case normalizing an exception put the
3104 recursion check value past its limit. Fixes crashers
3105 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003106
Georg Brandl3ee81df2008-05-17 18:14:43 +00003107- Patch #1031213: Decode source line in SyntaxErrors back to its

3111 with %G.
3112
Georg Brandl3ee81df2008-05-17 18:14:43 +00003113- Prevent expandtabs() on string and unicode objects from causing a
3114 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00003115

Neal Norwitz0ac60192007-05-27 04:08:54 +00003120- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003121 __*__ attributes. (Some already existed, e.g., __doc__ and
3122 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003123
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003124- Add -3 option to the interpreter to warn about features that are
3125 deprecated and will be changed/removed in Python 3.0.
3126
Georg Brandl2134e752007-05-21 20:34:16 +00003127- Patch #1686487: you can now pass any mapping after '**' in function
3128 calls.
3129
Collin Winter62903052007-05-18 23:11:24 +00003130- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003131 "except E as target:". This is to provide forwards compatibility
3132 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003133
Brett Cannon229cee22007-05-05 01:34:02 +00003134- Deprecate BaseException.message as per PEP 352.
3135
Georg Brandl3ee81df2008-05-17 18:14:43 +00003136- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003137 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003138
Vinay Sajip8549ce32007-05-06 17:53:37 +00003139- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003140 setting a plain string, ie don't expand to single letter identifiers.
3141
Raymond Hettinger13936692007-04-11 18:40:58 +00003142- Request #1191699: Slices can now be pickled.
3143
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003144- Request #1193128: str.translate() now allows a None argument for
3145 translations that only remove characters without re-mapping the
3146 remaining characters.
3147
Georg Brandl5cb76c12007-03-21 09:00:39 +00003148- Patch #1682205: a TypeError while unpacking an iterable is no longer
3149 masked by a generic one with the message "unpack non-sequence".
3150
Neal Norwitzaa754b72007-03-21 06:39:48 +00003151- Remove unused file Python/fmod.c.
3152
Guido van Rossum143b5642007-03-23 04:58:42 +00003153- Bug #1683368: The object.__init__() and object.__new__() methods are
3154 now stricter in rejecting excess arguments. The only time when
3155 either allows excess arguments is when it is not overridden and the
3156 other one is. For backwards compatibility, when both are
3157 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003158 warning later). Also, type.__init__() insists on the same signature
3159 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003160
Georg Brandl3ee81df2008-05-17 18:14:43 +00003161- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3162 object to complex using its __complex__() method before falling back
3163 to the __float__() method. Therefore, the functions in the cmath
3164 module now can operate on objects that define a __complex__()
3165 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003166
Georg Brandl3ee81df2008-05-17 18:14:43 +00003167- Patch #1623563: allow __class__ assignment for classes with
3168 __slots__. The old and the new class are still required to have the
3169 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003170
Georg Brandl3ee81df2008-05-17 18:14:43 +00003171- Patch #1642547: Fix an error/crash when encountering syntax errors
3172 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003174- Patch #1462488: Python no longer segfaults when
3175 ``object.__reduce_ex__()`` is called with an object that is faking
3176 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003177
Georg Brandl3ee81df2008-05-17 18:14:43 +00003178- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00003181- Patch #1444529: the builtin compile() now accepts keyword arguments.
3182
Georg Brandl7b9c5552007-03-12 14:30:05 +00003183- Bug #1678647: write a newline after printing an exception in any
3184 case, even when converting the value to a string failed.
3185
Georg Brandl871f1bc2007-03-12 13:17:36 +00003186- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003187 its argument, if it exists. If not, it will work like before. This
3188 allows customizing the output of dir() in the presence of a
3189 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003190
Collin Winter276887b2007-03-12 16:11:39 +00003191- Patch #922167: Python no longer segfaults when faced with infinitely
3192 self-recursive reload() calls (as reported by bug #742342).
3193
Georg Brandl3ee81df2008-05-17 18:14:43 +00003194- Patch #1675981: remove unreachable code from ``type.__new__()``
3195 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00003196
Georg Brandl3ee81df2008-05-17 18:14:43 +00003197- Patch #1491866: change the complex() constructor to allow
3198 parthensized forms. This means complex(repr(x)) now works instead of
3199 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003200
Georg Brandlaa2321b2007-03-07 00:40:28 +00003201- Patch #703779: unset __file__ in __main__ after running a file. This

3710 ".cpp" too.
3711
Facundo Batistad918a652007-04-24 13:54:38 +00003712- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003713 the client's request was successfully received, understood, and
3714 accepted. Now in these cases no error is raised in urllib (issue
3715 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00003716

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00003723- Added a timeout parameter to the constructor of other protocols
3724 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3725 work started with create_connection() and timeout in httplib, and
3726 closes patch #723312.
3727
Vinay Sajip8549ce32007-05-06 17:53:37 +00003728- Patch #1676823: Added create_connection() to socket.py, which may be
3729 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00003730 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00003731
Martin v. Löwis0af33882007-03-23 13:27:15 +00003732- Bug #978833: Revert r50844, as it broke _socketobject.dup.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003739- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
3740 to True (which is not the default), it visits symlinks pointing to
Georg Brandlcae9f3d2007-03-21 09:10:29 +00003741 directories.
3742

3752
Georg Brandlf66b6032007-03-14 08:27:52 +00003753- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00003754 AttributeError instead of an IOError when the server's response
3755 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003756
Georg Brandl3ee81df2008-05-17 18:14:43 +00003757- Patch #957650: "%var%" environment variable references are now
3758 properly expanded in ntpath.expandvars(), also "~user" home
3759 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00003760
Georg Brandl3ee81df2008-05-17 18:14:43 +00003761- Patch #1429539: pdb now correctly initializes the __main__ module
3762 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003763 correctly now.
3764
Georg Brandlbad6f192007-03-13 21:32:56 +00003765- The nonobvious commands.getstatus() function is now deprecated.

3771
Georg Brandl3ee81df2008-05-17 18:14:43 +00003772- Patch #1530482: add pydoc.render_doc() which returns the
3773 documentation for a thing instead of paging it to stdout, which
3774 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00003775
Georg Brandl3ee81df2008-05-17 18:14:43 +00003776- Patch #1533909: the timeit module now accepts callables in addition

3782 parameter which can be set to False to prevent the default
3783 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00003785- Patch #1581073: add a flag to textwrap that prevents the dropping of
3786 whitespace while wrapping.
3787
Georg Brandl92a6bae2007-03-13 17:43:32 +00003788- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003789 are set for invalid interpolation sequences that would lead to
3790 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00003791

3804
Georg Brandl94fe3f52007-03-13 09:32:11 +00003805- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00003806 field names in its exception message if you try to write a record
3807 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00003825

3833 returned string up to the first NUL character.
3834

3844
Georg Brandl3ee81df2008-05-17 18:14:43 +00003845- unittest now verifies more of its assumptions. In particular,
3846 TestCase and TestSuite subclasses (not instances) are no longer
3847 accepted in TestSuite.addTest(). This should cause no
3848 incompatibility since it never made sense with ordinary subclasses
3849 -- the failure just occurred later, with a more cumbersome
3850 exception.

3859 given a unicode argument and os.listdir() returns unicode filenames.
3860
Georg Brandl3ee81df2008-05-17 18:14:43 +00003861- Patch #1673619: setup.py identifies extension modules it doesn't

3863 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004239 time so that opening a database previously created with the DB_DUP
4240 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4241 opens. Specifically: dictionary assignment to a DB object will
4242 replace all values for a given key when the database allows
4243 duplicate values. DB users should use DB.put(k, v) when they want
4244 to store duplicates; not DB[k] = v.

4251 characters with ASCII value less than 32. Also, it correctly quotes
4252 dots only if they occur on a single line, as opposed to the previous
4253 behavior of quoting dots if they are the second character of any
4254 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004255
