965 an existing .py counterpart, override the co_filename attributes of all
966 code objects if the original filename is obsolete (which can happen if the

Georg Brandld2094602008-12-05 08:51:30 +00001006 method on file objects with closefd=False. The file descriptor is still
1007 kept open but the file object behaves like a closed file. The ``FileIO``
1008 object also got a new readonly attribute ``closefd``.

1218
1219- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
1220 302 conformant loader) will now work correctly in most cases (they
1221 are still subject to the constraints that exist for all code running

1381What's New in Python 2.6.1
1382==========================
1383
1384*Release date: 04-Dec-2008*
1385
1386Core and Builtins
1387-----------------
1388
1389- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1390 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1391 instead of throwing a MemoryError.
1392
1393- Issue #4367: Python would segfault during compiling when the unicodedata
1394 module couldn't be imported and \N escapes were present.
1395
1396- Issue #4348: Some bytearray methods returned that didn't cause any change to
1397 the bytearray, returned the same bytearray instead of a copy.
1398
1399- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1400
1401- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1402
1403- Issue #4048: The parser module now correctly validates relative imports.
1404
1405- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

1409 method does not return iterators for the 4th and 5th items.
1410
1411- Issue #4209: Enabling unicode_literals and the print_function in the same
1412 __future__ import didn't work.
1413
1414- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1415 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1416 really executed because I cannot move to such directory on win2k)
1417
1418- Issue #4069: When set.remove(element) is used with a set element, the element
1419 is temporarily replaced with an equivalent frozenset. But the eventual
1420 KeyError would always report the empty frozenset([]) as the missing key. Now
1421 it correctly refers to the initial element.
1422
1423- Fixed C99 style comments in several files. Python is now C89 compatible
1424 again.

1575 PY_FORMAT_SIZE_T is designed to select the correct format for the OS

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001589- Issue #3751: str.rpartition would perform a left-partition when called with
1590 a unicode argument.
1591
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001592- Issue #3683: Fix compilation when --without-threads is given.
1593
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001594- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001595 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001596 was correctly parsed but parsing of subsequent arguments failed.
1597
Vinay Sajip35e3b032008-09-01 14:33:59 +00001598- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001599 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1600 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1601 when given a tuple of classes as second argument, were looking up
1602 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1603 type object.
1604
Neal Norwitz18aa3882008-08-24 05:04:52 +00001605- Fix crashes on memory allocation failure found with failmalloc.

1674 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1675 for catch_warnings() also led to an improvement in the raising of a
1676 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001698- Issue #2975: When compiling several extension modules with Visual Studio 2008
1699 from the same python interpreter, some environment variables would grow
1700 without limit.
1701
Benjamin Peterson37346b22008-08-23 20:27:43 +00001702- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001739What's New in Python 2.6 beta 3?
1740================================
1741
Barry Warsaw07a4a382008-08-21 01:15:08 +00001742*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001743
1744Core and Builtins
1745-----------------
1746
Guido van Rossumf8402962008-08-20 15:01:50 +00001747- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1748 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1749 extensions do not automatically benefit from the class attribute
1750 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1751 to their tp_flags field if they care. This is a backwards
1752 compatibility feature; in 3.0, all types will use the cache by
1753 default.
1754
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001755- Keyword arguments can now follow starred arguments. (``f(a, *args,
1756 keyword=23)`` is now valid syntax.)
1757
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001758- ctypes function pointers that are COM methods have a boolean True
1759 value again.
1760
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001761- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1762 by denying s# to parse objects that have a releasebuffer procedure,
1763 and introducing s*.
1764
Georg Brandl1e13ea92008-08-11 09:07:59 +00001765- Issue #3537: Fix an assertion failure when an empty but presized dict
1766 object was stored in the freelist.
1767
Mark Dickinsonb6467572008-08-04 21:30:09 +00001768- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1769 ValueError consistently across platforms.
1770
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001771- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1772 (64bit Unix, for example), unichr() would truncate its argument and return
1773 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1774
Neal Norwitze7d8be82008-07-31 17:17:14 +00001775- Apply security patches from Apple.
1776
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001777- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1778 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1779
Antoine Pitrou92f82162008-07-25 22:22:08 +00001780- Issue #1819: function calls with several named parameters are now on
1781 average 35% faster (as measured by pybench).
1782
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001783- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1784 the python debugger steps into a class statement: the free variables (local
1785 variables defined in an outer scope) would be deleted from the outer scope.
1786
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001787- Issue #2620: Overflow checking when allocating or reallocating memory
1788 was not always being done properly in some python types and extension
1789 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1790 all been updated to perform better checks and places in the code that
1791 would previously leak memory on the error path when such an allocation
1792 failed have been fixed.

1795-------
1796
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001797- Issue #3612: Added some missing basic types in ctypes.wintypes.
1798
Benjamin Petersone977ad42008-08-20 01:42:01 +00001799- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1800 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1801
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001802- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1803 version reported by these tools does not necessarily follow the python
1804 version numbering scheme, so the module is less strict when parsing it.
1805
Nick Coghlanf70385a2008-08-18 12:42:46 +00001806- Issue #2235: Added Py3k warnings for types which will become unhashable
1807 under the stricter __hash__ inheritance rules in 3.0. Several types
1808 which did not meet the rules for hash invariants and were already
1809 unhashable in 3.0 have now been explicitly flagged as unhashable in
1810 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1811 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1812
Brett Cannon88f801d2008-08-18 00:46:22 +00001813- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1814 imported into the module but exposed as part of the module's API.
1815
Brett Cannon7b96f072008-08-18 00:41:11 +00001816- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1817
Brett Cannon46225e72008-08-18 00:36:52 +00001818- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1819
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001820- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1821
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001822- Issue #3575: Incremental decoder's decode function now takes bytearray
1823 by using 's*' instead of 't#'.
1824
Jesus Cea585ad8a2009-07-02 15:37:21 +00001825- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001826 fails unicode conversion on 2nd parameter. (windows only)
1827
Facundo Batista94f243a2008-08-17 03:38:39 +00001828- Issue 2464. urllib2 now supports a malformation in the URL received
1829 in a redirect.
1830
Brett Cannonabe423e2008-08-16 21:47:07 +00001831- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001832 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001833
Facundo Batistaeb90b782008-08-16 14:44:07 +00001834- Issue #2776: fixed small issue when handling an URL with double slash
1835 after a 302 response in the case of not going through a proxy.
1836
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001837- Issue #2676: in the email package, content-type parsing was hanging on
1838 pathological input because of quadratic or exponential behaviour of a
1839 regular expression.
1840
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001841- Issue #3476: binary buffered reading through the new "io" library is now
1842 thread-safe.
1843
Brett Cannonbf3157b2008-08-14 05:00:03 +00001844- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1845 since mimetools itself is deprecated. Because modules are cached, all
1846 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1847
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001848- Issue #3134: shutil referenced undefined WindowsError symbol.
1849
Robert Schuppenies14646332008-08-10 11:01:53 +00001850- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1851 menu entries were not deleted.
1852
Brett Cannon83e81842008-08-09 23:30:55 +00001853- Copied the implementation of reduce() to _functools.reduce() to have a
1854 version that did not raise a DeprecationWarning under -3.
1855
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001856- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1857 a MemoryError rather than silently stop the iteration.
1858
Guido van Rossum59ce9012008-08-09 14:55:34 +00001859- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1860 to _sre.compile() will now be rejected. This should not affect anybody
1861 since the re.compile() function never generates invalid re-bytecode.
1862
Skip Montanaroa032bf42008-08-08 22:52:51 +00001863- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1864 upon first access it can be automatically initialized from the csv file if
1865 it wasn't initialized during instantiation.
1866
Brett Cannon3aa2a492008-08-06 22:28:09 +00001867- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1868 the reload() built-in has been removed.
1869
Brett Cannon7e30b672008-08-04 21:52:25 +00001870- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001871 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00001872 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
1873 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,

Antoine Pitroude781a42008-08-09 12:43:23 +00001882 asking for a specific length. This problem only affected files opened

1939-----------------
1940
Georg Brandl3e483f62008-07-16 22:57:41 +00001941- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1942 its methods now allow for items objects that can be converted to
1943 an integer using operator.index().
1944
Mark Dickinson64b7e502008-07-16 09:40:03 +00001945- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1946 produced a ValueError instead of giving the correct float.
1947
Eric Smitha5fa5a22008-07-16 00:11:49 +00001948- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1949 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1950
Mark Dickinson7103aa42008-07-15 19:08:33 +00001951- Issue #3008: the float type has a new instance method 'float.hex'
1952 and a new class method 'float.fromhex' to convert floating-point
1953 numbers to and from hexadecimal strings, respectively.
1954
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001955- Issue #2235: __hash__ is once again inherited by default. To allow
1956 collections.Hashable to remain meaningful in the presence of the
1957 default hash implementation (object.__hash__), it is now possible
1958 to explicit block inheritance of hash by setting __hash__=None at
1959 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1960 level.
1961
Nick Coghlanb028f502008-07-13 14:52:36 +00001962- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1963 the parent module cannot be found while performing an absolute import.
1964 This means that an incorrectly defined __package__ attribute will
1965 now only prevent relative imports in that module rather than causing
1966 all imports from that module to fail.
1967
Nick Coghlan14ff9942008-07-08 14:21:42 +00001968- Issue #2517: Allow unicode messages in Exceptions again by correctly

1978 another thread's dictionary.
1979
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001980- Issue #3004: Minor change to slice.indices(): the start and stop
1981 arguments are now treated identically, making the behaviour easier
1982 to describe and understand. For example, slice(None, -10,
1983 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1984 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1985 10, -1).
1986
Georg Brandl278fc502008-07-19 12:46:12 +00001987- Issue #3219: Calling a function with repeated keyword arguments,
1988 f(a=2, a=23), would not cause a syntax error. This was a regression
1989 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002027- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2028 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002029 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002030 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002046- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

2443 - ``--with-universal-archs=all``: install 4-way universal
2444
2445 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2446
2447 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2448
2449 This option should be used in combination with ``--enable-universalsdk=``.
2450
2451 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

2456
Georg Brandl74a1dea2008-05-28 11:21:39 +00002457- Add ``PyType_Modified()`` as a public API to clear the type cache.
2458
2459- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00002460
2461- The PyString functions have been renamed to PyBytes. A batch of
2462 defines were added so that the linker still sees the original
2463 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002501- Issue #1631171: Re-implement the 'warnings' module in C (the
2502 original Python code has been kept as backup). This will allow for
2503 using the 'warning's machinery in such places as the parser where
2504 use of pure Python code is not possible. Both the ``showarning()``
2505 and ``formatwarning()`` gain an optional 'line' argument which is
2506 not called by default for backwards-compatibility reasons. Setting
2507 ``warnings.showwarning()`` to an implementation that lacks support
2508 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002550- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002551 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002571- Issue #2550: The approach used by client/server code for obtaining
2572 ports to listen on in network-oriented tests has been refined in an
2573 effort to facilitate running multiple instances of the entire
2574 regression test suite in parallel without issue.
2575 test_support.bind_port() has been fixed such that it will always
2576 return a unique port -- which wasn't always the case with the
2577 previous implementation, especially if socket options had been set
2578 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2579 new implementation of bind_port() will actually raise an exception
2580 if it is passed an AF_INET/SOCK_STREAM socket with either the
2581 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2582 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2583 the socket it's been passed. This currently only applies to
2584 Windows. This option prevents any other sockets from binding to the
2585 host/port we've bound to, thus removing the possibility of the
2586 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2587 when a second SOCK_STREAM socket binds and accepts to a host/port
2588 that's already been bound by another socket. The optional preferred
2589 port parameter to bind_port() has been removed. Under no
2590 circumstances should tests be hard coding ports!
2591
2592 test_support.find_unused_port() has also been introduced, which will
2593 pass a temporary socket object to bind_port() in order to obtain an
2594 unused port. The temporary socket object is then closed and
2595 deleted, and the port is returned. This method should only be used
2596 for obtaining an unused port in order to pass to an external program
2597 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2598 a parameter to a server-oriented class that doesn't give you direct
2599 access to the underlying socket used.
2600
2601 Finally, test_support.HOST has been introduced, which should be used
2602 for the host argument of any relevant socket calls (i.e. bind and
2603 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002604
2605 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002606 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002607 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2608 test_asynchat and test_socket_ssl.
2609
Georg Brandl3ee81df2008-05-17 18:14:43 +00002610 It is now possible for multiple instances of the regression test
2611 suite to run in parallel without issue.

2878-----------------
2879
Fred Drakea8ee94b2008-03-01 02:45:07 +00002880- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002881 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00002883- Issue #2067: file.__exit__() now calls subclasses' close() method.
2884
2885- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002886
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002887- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002888 issue 215555 for a discussion.
2889
Eric Smitha73fbe72008-02-23 03:09:44 +00002890- Added the future_builtins module, which contains hex() and oct().
2891 These are the PEP 3127 version of these functions, designed to be
2892 compatible with the hex() and oct() builtins from Python 3.0. They
2893 differ slightly in their output formats from the existing, unchanged
2894 Python 2.6 builtins. The expected usage of the future_builtins
2895 module is:
2896 from future_builtins import hex, oct
2897
Eric Smith7ef40bf2008-02-20 23:34:22 +00002898- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2899 exponents for exponents with absolute value < 100. Follows C99
2900 standard. This is a change on Windows, which would use 3 digits.
2901 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2902 so that any alterations it does to the resulting string will be
2903 available in stringlib/formatter.h (for float.__format__).
2904
Eric Smith5a3c1352008-02-19 13:21:56 +00002905- Implemented PEP 3101, Advanced String Formatting. This adds a new
2906 builtin format(); a format() method for str and unicode; a
2907 __format__() method to object, str, unicode, int, long, float, and
2908 datetime; the class string.Formatter; and the C API
2909 PyObject_Format().
2910
Georg Brandl3ee81df2008-05-17 18:14:43 +00002911- Fixed several potential crashes, all caused by specially crafted
2912 __del__ methods exploiting objects in temporarily inconsistent
2913 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002914
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002915- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002916 prevent a possible crash: an Abstract Base Class would try to access
2917 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002918

Georg Brandl3ee81df2008-05-17 18:14:43 +00002922- Clear all free lists during a gc.collect() of the highest generation
2923 in order to allow pymalloc to free more arenas. Python may give back
2924 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002925
Georg Brandl3ee81df2008-05-17 18:14:43 +00002926- Issue #2045: Fix an infinite recursion triggered when printing a
2927 subclass of collections.defaultdict, if its default_factory is set
2928 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002929
Christian Heimesf75dbef2008-02-08 00:11:31 +00002930- Fixed a minor memory leak in dictobject.c. The content of the free
2931 list was not freed on interpreter shutdown.
2932
Georg Brandl5a7eca12010-03-21 19:29:04 +00002933- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00002934 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002935
Georg Brandl3ee81df2008-05-17 18:14:43 +00002936- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2937 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002938 to compact the internal free lists of pre-allocted ints and floats.
2939
Georg Brandl3ee81df2008-05-17 18:14:43 +00002940- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2941 calls. Python expected the return type int but the fork familie
2942 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002943

2954 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002955
Georg Brandl3ee81df2008-05-17 18:14:43 +00002956- Patch #1473257: generator objects gain a gi_code attribute. This is
2957 the same object as the func_code attribute of the function that
2958 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002959
Georg Brandl3ee81df2008-05-17 18:14:43 +00002960- Issue #1920: "while 0" statements were completely removed by the
2961 compiler, even in the presence of an "else" clause, which is

2963 correctly emits bytecode for the "else" suite.

Guido van Rossumeead05f2008-01-24 18:21:02 +00002965- A few crashers fixed: weakref_in_del.py (issue #1377858);
2966 loosing_dict_ref.py (issue #1303614, test67.py);
2967 borrowed_ref_[34].py (not in tracker).
2968
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002969- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002970 suppressed while an extension is loaded by calling SetErrorMode in
2971 dynload_win.c. The error is still reported properly.
2972
Georg Brandl3ee81df2008-05-17 18:14:43 +00002973- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002974 several extension methods and modules do not work without unicode
2975 support.
2976
Georg Brandl26543b12008-01-21 18:36:51 +00002977- Issue #1882: when compiling code from a string, encoding cookies in the
2978 second line of code were not always recognized correctly.
2979
Georg Brandl14404b62008-01-19 19:27:05 +00002980- Issue #1679: "0x" was taken as a valid integer literal.
2981
Georg Brandl6caad7d2008-01-26 14:19:22 +00002982- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002983 added.
2984
Christian Heimesc94e2b52008-01-14 04:13:37 +00002985- sys.float_info / PyFloat_GetInfo: The floating point information
2986 object was converted from a dict to a specialized structseq object.
2987
Georg Brandl3ee81df2008-05-17 18:14:43 +00002988- Patch #1816: Added sys.flags structseq. It exposes the status of
2989 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002990
Georg Brandl3ee81df2008-05-17 18:14:43 +00002991- Objects/structseq.c: Implemented new structseq representation. The
2992 patch makes structseqs (e.g. the return value of os.stat) more
2993 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002994
Georg Brandl3ee81df2008-05-17 18:14:43 +00002995- Patch #1700288: added a type attribute cache that caches method
2996 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002997
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002998- Bug #1776: __import__() no longer accepts filenames on any platform.
2999 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003000
Georg Brandlaed6c662008-01-07 17:25:53 +00003001- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3002
Georg Brandl3ee81df2008-05-17 18:14:43 +00003003- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3004 envvar and sys.dont_write_bytecode attribute. All these can be set
3005 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003006
Georg Brandl3ee81df2008-05-17 18:14:43 +00003007- Improve some exception messages when Windows fails to load an
3008 extension module. Now we get for example '%1 is not a valid Win32
3009 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003010
Georg Brandl3ee81df2008-05-17 18:14:43 +00003011- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003013- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3014 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003015
Christian Heimes0a8143f2007-12-18 23:22:54 +00003016- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003017 and INF. float("nan"), float("inf") and float("-inf") now work on
3018 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003019
Georg Brandl3ee81df2008-05-17 18:14:43 +00003020- Compiler now generates simpler and faster code for dictionary
3021 literals. The oparg for BUILD_MAP now indicates an estimated
3022 dictionary size. There is a new opcode, STORE_MAP, for adding
3023 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003052- Patch #1739468: Directories and zipfiles containing a __main__.py
3053 file can now be directly executed by passing their name to the
3054 interpreter. The directory/zipfile is automatically inserted as the
3055 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003056
Georg Brandl3ee81df2008-05-17 18:14:43 +00003057- Issue #1265: Fix a problem with sys.settrace, if the tracing
3058 function uses a generator expression when at the same time the
3059 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003060
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003061- sets and frozensets now have an isdisjoint() method.
3062
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003063- optimize the performance of builtin.sum().
3064
Neal Norwitz44f326e2007-10-05 05:29:17 +00003065- Fix warnings found by the new version of the Coverity checker.
3066
Georg Brandl5a7eca12010-03-21 19:29:04 +00003067- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003068 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3069 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003070
Georg Brandl3ee81df2008-05-17 18:14:43 +00003071- Issue #1686386: Tuple's tp_repr did not take into account the
3072 possibility of having a self-referential tuple, which is possible
3073 from C code. Nor did object's tp_str consider that a type's tp_str
3074 could do something that could lead to an inifinite recursion.
3075 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3076 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003077
Georg Brandl3ee81df2008-05-17 18:14:43 +00003078- Issue #1164: It was possible to trigger deadlock when using the
3079 'print' statement to write to a file since the GIL was not released
3080 as needed. Now PyObject_Print() does the right thing along with
3081 various tp_print implementations of the built-in types and those in
3082 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003083
Georg Brandl3ee81df2008-05-17 18:14:43 +00003084- Issue #1147: Exceptions were directly allowing string exceptions in
3085 their throw() method even though string exceptions no longer
3086 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003087
Georg Brandl3ee81df2008-05-17 18:14:43 +00003088- Issue #1096: Prevent a segfault from getting the repr of a very
3089 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003090
Brett Cannon1e534b52007-09-07 04:18:30 +00003091- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003092 PyObject_Call() never calling back out to Python code to trigger
3093 recursion depth updates/checks. Required the creation of a static
3094 RuntimeError instance in case normalizing an exception put the
3095 recursion check value past its limit. Fixes crashers
3096 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003097
Georg Brandl3ee81df2008-05-17 18:14:43 +00003098- Patch #1031213: Decode source line in SyntaxErrors back to its

3102 with %G.
3103
Georg Brandl3ee81df2008-05-17 18:14:43 +00003104- Prevent expandtabs() on string and unicode objects from causing a

Neal Norwitz0ac60192007-05-27 04:08:54 +00003111- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003112 __*__ attributes. (Some already existed, e.g., __doc__ and
3113 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003114
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003115- Add -3 option to the interpreter to warn about features that are
3116 deprecated and will be changed/removed in Python 3.0.
3117
Georg Brandl2134e752007-05-21 20:34:16 +00003118- Patch #1686487: you can now pass any mapping after '**' in function
3119 calls.
3120
Collin Winter62903052007-05-18 23:11:24 +00003121- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003122 "except E as target:". This is to provide forwards compatibility
3123 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003124
Brett Cannon229cee22007-05-05 01:34:02 +00003125- Deprecate BaseException.message as per PEP 352.
3126
Georg Brandl3ee81df2008-05-17 18:14:43 +00003127- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003128 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003129
Vinay Sajip8549ce32007-05-06 17:53:37 +00003130- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003131 setting a plain string, ie don't expand to single letter identifiers.
3132
Raymond Hettinger13936692007-04-11 18:40:58 +00003133- Request #1191699: Slices can now be pickled.
3134
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003135- Request #1193128: str.translate() now allows a None argument for
3136 translations that only remove characters without re-mapping the
3137 remaining characters.
3138
Georg Brandl5cb76c12007-03-21 09:00:39 +00003139- Patch #1682205: a TypeError while unpacking an iterable is no longer
3140 masked by a generic one with the message "unpack non-sequence".
3141
Neal Norwitzaa754b72007-03-21 06:39:48 +00003142- Remove unused file Python/fmod.c.
3143
Guido van Rossum143b5642007-03-23 04:58:42 +00003144- Bug #1683368: The object.__init__() and object.__new__() methods are
3145 now stricter in rejecting excess arguments. The only time when
3146 either allows excess arguments is when it is not overridden and the
3147 other one is. For backwards compatibility, when both are
3148 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003149 warning later). Also, type.__init__() insists on the same signature
3150 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003151
Georg Brandl3ee81df2008-05-17 18:14:43 +00003152- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3153 object to complex using its __complex__() method before falling back
3154 to the __float__() method. Therefore, the functions in the cmath
3155 module now can operate on objects that define a __complex__()
3156 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003157
Georg Brandl3ee81df2008-05-17 18:14:43 +00003158- Patch #1623563: allow __class__ assignment for classes with
3159 __slots__. The old and the new class are still required to have the
3160 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003161
Georg Brandl3ee81df2008-05-17 18:14:43 +00003162- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00003165- Patch #1462488: Python no longer segfaults when
3166 ``object.__reduce_ex__()`` is called with an object that is faking
3167 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003168
Georg Brandl3ee81df2008-05-17 18:14:43 +00003169- Patch #1680015: Don't modify __slots__ tuple if it contains an

3173
Georg Brandl7b9c5552007-03-12 14:30:05 +00003174- Bug #1678647: write a newline after printing an exception in any
3175 case, even when converting the value to a string failed.
3176
Georg Brandl871f1bc2007-03-12 13:17:36 +00003177- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003178 its argument, if it exists. If not, it will work like before. This
3179 allows customizing the output of dir() in the presence of a
3180 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00003182- Patch #922167: Python no longer segfaults when faced with infinitely
3183 self-recursive reload() calls (as reported by bug #742342).
3184
Georg Brandl3ee81df2008-05-17 18:14:43 +00003185- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00003188- Patch #1491866: change the complex() constructor to allow
3189 parthensized forms. This means complex(repr(x)) now works instead of
3190 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003191
Georg Brandlaa2321b2007-03-07 00:40:28 +00003192- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003193 makes the filenames the warning module prints much more sensible
3194 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003195
Georg Brandl49aafc92007-03-07 00:34:46 +00003196- Variant of patch #697613: don't exit the interpreter on a SystemExit
3197 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003198 variable is given, but break into the interactive interpreter just
3199 like on other exceptions or normal program exit.

3700 (as opposed to the command line) will now write file names ending in
3701 ".cpp" too.
3702
Facundo Batistad918a652007-04-24 13:54:38 +00003703- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003704 the client's request was successfully received, understood, and
3705 accepted. Now in these cases no error is raised in urllib (issue
3706 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00003707

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00003714- Added a timeout parameter to the constructor of other protocols
3715 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3716 work started with create_connection() and timeout in httplib, and
3717 closes patch #723312.
3718
Vinay Sajip8549ce32007-05-06 17:53:37 +00003719- Patch #1676823: Added create_connection() to socket.py, which may be
3720 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00003721 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00003722
Martin v. Löwis0af33882007-03-23 13:27:15 +00003723- Bug #978833: Revert r50844, as it broke _socketobject.dup.

3743
Georg Brandlf66b6032007-03-14 08:27:52 +00003744- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00003745 AttributeError instead of an IOError when the server's response
3746 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003747
Georg Brandl3ee81df2008-05-17 18:14:43 +00003748- Patch #957650: "%var%" environment variable references are now
3749 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl03b90d82007-03-13 22:07:36 +00003751
Georg Brandl3ee81df2008-05-17 18:14:43 +00003752- Patch #1429539: pdb now correctly initializes the __main__ module
3753 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003754 correctly now.
3755
Georg Brandlbad6f192007-03-13 21:32:56 +00003756- The nonobvious commands.getstatus() function is now deprecated.

3762
Georg Brandl3ee81df2008-05-17 18:14:43 +00003763- Patch #1530482: add pydoc.render_doc() which returns the
3764 documentation for a thing instead of paging it to stdout, which
3765 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00003766
Georg Brandl3ee81df2008-05-17 18:14:43 +00003767- Patch #1533909: the timeit module now accepts callables in addition

3773 parameter which can be set to False to prevent the default
3774 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00003776- Patch #1581073: add a flag to textwrap that prevents the dropping of
3777 whitespace while wrapping.
3778
Georg Brandl92a6bae2007-03-13 17:43:32 +00003779- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003780 are set for invalid interpolation sequences that would lead to
3781 errors on reading back those values.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003797 field names in its exception message if you try to write a record
3798 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00003816

3824 returned string up to the first NUL character.
3825

3835
Georg Brandl3ee81df2008-05-17 18:14:43 +00003836- unittest now verifies more of its assumptions. In particular,
3837 TestCase and TestSuite subclasses (not instances) are no longer
3838 accepted in TestSuite.addTest(). This should cause no
3839 incompatibility since it never made sense with ordinary subclasses
3840 -- the failure just occurred later, with a more cumbersome
3841 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00003842

3850 given a unicode argument and os.listdir() returns unicode filenames.
3851
Georg Brandl3ee81df2008-05-17 18:14:43 +00003852- Patch #1673619: setup.py identifies extension modules it doesn't
3853 know how to build and those it knows how to build but that fail to
3854 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004230 time so that opening a database previously created with the DB_DUP
4231 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4232 opens. Specifically: dictionary assignment to a DB object will
4233 replace all values for a given key when the database allows
4234 duplicate values. DB users should use DB.put(k, v) when they want
4235 to store duplicates; not DB[k] = v.

4242 characters with ASCII value less than 32. Also, it correctly quotes
4243 dots only if they occur on a single line, as opposed to the previous
4244 behavior of quoting dots if they are the second character of any
4245 line.
