124 rejected; (2) parsing of strings representing infinities and nans
125 was locale aware; and (3) the interpretation of fromhex('-nan')
126 didn't match that of float('-nan').
127
Eric Smitha985a3a2009-05-05 18:26:08 +0000128- Issue #5920: For float.__format__, change the behavior with the
129 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
130 to be like 'g' but with at least one decimal point and with a
131 default precision of 12. Previously, the behavior the same but with
132 a default precision of 6. This more closely matches str(), and
133 reduces surprises when adding alignment flags to the empty
134 presentation type. This also affects the new complex.__format__ in
135 the same way.
136
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000137- Issue #5890: in subclasses of 'property' the __doc__ attribute was

Eric Smith9139cc62009-04-30 00:58:58 +0000180 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000181
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000182- Issue #5759: float() didn't call __float__ on str subclasses.

200 untrackable objects are not tracked by the garbage collector. This can
201 reduce the size of collections and therefore the garbage collection overhead
202 on long-running programs, depending on their particular use of datatypes.
203
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000204- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

209 2**15 for the internal representation of integers, for performance
210 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
211 --enable-big-digits option to configure, which overrides the
212 default. Add sys.long_info structseq to provide information about
213 the internal format.
214

224
Brett Cannon6c4cff02009-03-11 04:51:06 +0000225- Issue #3652: Make the 'line' argument for warnings.showwarning() a
226 requirement. Means the DeprecationWarning from Python 2.6 can go away.

233 for ints and longs.
234
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000235- Issue #5260: Long integers now consume less memory: average
236 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
237 on a 64-bit system.
238
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000239- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
240 rotating the object pointer by 4 bits to the right.

244
Benjamin Petersone18ef192009-01-20 14:21:16 +0000245- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
246
Georg Brandl29c6a282009-04-05 20:23:13 +0000247- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000248 were suppressing all exceptions. These include list(), filter(), map(),
249 zip(), and bytearray().
250

305 fail.
306
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000307- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

321
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000322- Issue #4445: Replace "sizeof(PyStringObject)" with
323 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
324 str instances. On a typical machine this saves 3 bytes of memory
325 (on average) per string allocation.
326
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000327- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

329 instead of throwing a MemoryError.
330
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000331- Issue #3689: The list reversed iterator now supports __length_hint__

Vinay Sajip213faca2008-12-03 23:22:58 +0000337- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000338 method on file objects with closefd=False. The file descriptor is still
339 kept open but the file object behaves like a closed file. The ``FileIO``
340 object also got a new readonly attribute ``closefd``.
341
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000342- Issue #4348: Some bytearray methods returned that didn't cause any change to

356
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000357- Issue #4209: Enabling unicode_literals and the print_function in the same
358 __future__ import didn't work.
359
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000360- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000361 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000362
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000363- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
364 returned a path longer than MAX_PATH. (But It's doubtful this code path is
365 really executed because I cannot move to such directory on win2k)
366
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000367- Issue #4069: When set.remove(element) is used with a set element, the element
368 is temporarily replaced with an equivalent frozenset. But the eventual
369 KeyError would always report the empty frozenset([]) as the missing key. Now
370 it correctly refers to the initial element.
371
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000372- Issue #4509: Various issues surrounding resize of bytearray objects to

388 returned them on 64bit platforms.
389
Walter Dörwalded960ac2009-05-03 22:36:33 +0000390- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
391 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
392 step. This avoids problems with counting UTF-8 bytes that ignores the effect
393 of using the replace error handler in PyUnicode_DecodeUTF8().
394
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000395- Issue #3739: The unicode-internal encoder now reports the number of characters

1579
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001580- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1581 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1582 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1583 ``printf`` function, whereas PyString_FromFormat has an independent
1584 implementation and uses "%zd" on all platforms for size_t values.
1585 This makes a difference on win64, where ``printf`` needs "%Id" to display
1586 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001588- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1592 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001603 was correctly parsed but parsing of subsequent arguments failed.
1604
Vinay Sajip35e3b032008-09-01 14:33:59 +00001605- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001606 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1607 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1608 when given a tuple of classes as second argument, were looking up
1609 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1610 type object.
1611

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001749What's New in Python 2.6 beta 3?
1750================================
1751
Barry Warsaw07a4a382008-08-21 01:15:08 +00001752*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001753
1754Core and Builtins
1755-----------------
1756
Guido van Rossumf8402962008-08-20 15:01:50 +00001757- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1758 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1759 extensions do not automatically benefit from the class attribute
1760 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1761 to their tp_flags field if they care. This is a backwards
1762 compatibility feature; in 3.0, all types will use the cache by
1763 default.
1764
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001765- Keyword arguments can now follow starred arguments. (``f(a, *args,
1766 keyword=23)`` is now valid syntax.)
1767
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001768- ctypes function pointers that are COM methods have a boolean True
1769 value again.
1770
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001771- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1772 by denying s# to parse objects that have a releasebuffer procedure,
1773 and introducing s*.
1774
Georg Brandl1e13ea92008-08-11 09:07:59 +00001775- Issue #3537: Fix an assertion failure when an empty but presized dict
1776 object was stored in the freelist.
1777
Mark Dickinsonb6467572008-08-04 21:30:09 +00001778- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1779 ValueError consistently across platforms.
1780
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001781- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1782 (64bit Unix, for example), unichr() would truncate its argument and return
1783 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1784
Neal Norwitze7d8be82008-07-31 17:17:14 +00001785- Apply security patches from Apple.
1786
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001787- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1788 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1789
Antoine Pitrou92f82162008-07-25 22:22:08 +00001790- Issue #1819: function calls with several named parameters are now on
1791 average 35% faster (as measured by pybench).
1792
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001793- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1794 the python debugger steps into a class statement: the free variables (local
1795 variables defined in an outer scope) would be deleted from the outer scope.
1796
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001797- Issue #2620: Overflow checking when allocating or reallocating memory
1798 was not always being done properly in some python types and extension
1799 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1800 all been updated to perform better checks and places in the code that
1801 would previously leak memory on the error path when such an allocation
1802 failed have been fixed.
1803
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001804Library
1805-------
1806
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001807- Issue #3612: Added some missing basic types in ctypes.wintypes.
1808
Benjamin Petersone977ad42008-08-20 01:42:01 +00001809- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1810 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1811
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001812- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1813 version reported by these tools does not necessarily follow the python
1814 version numbering scheme, so the module is less strict when parsing it.
1815
Nick Coghlanf70385a2008-08-18 12:42:46 +00001816- Issue #2235: Added Py3k warnings for types which will become unhashable
1817 under the stricter __hash__ inheritance rules in 3.0. Several types
1818 which did not meet the rules for hash invariants and were already
1819 unhashable in 3.0 have now been explicitly flagged as unhashable in
1820 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1821 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1822
Brett Cannon88f801d2008-08-18 00:46:22 +00001823- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1824 imported into the module but exposed as part of the module's API.
1825
Brett Cannon7b96f072008-08-18 00:41:11 +00001826- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1827
Brett Cannon46225e72008-08-18 00:36:52 +00001828- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1829
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001830- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1831
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001832- Issue #3575: Incremental decoder's decode function now takes bytearray
1833 by using 's*' instead of 't#'.
1834
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001835- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001836 fails unicode conversion on 2nd parameter. (windows only)
1837
Facundo Batista94f243a2008-08-17 03:38:39 +00001838- Issue 2464. urllib2 now supports a malformation in the URL received
1839 in a redirect.
1840
Brett Cannonabe423e2008-08-16 21:47:07 +00001841- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001842 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001843
Facundo Batistaeb90b782008-08-16 14:44:07 +00001844- Issue #2776: fixed small issue when handling an URL with double slash
1845 after a 302 response in the case of not going through a proxy.
1846
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001847- Issue #2676: in the email package, content-type parsing was hanging on
1848 pathological input because of quadratic or exponential behaviour of a
1849 regular expression.
1850
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001851- Issue #3476: binary buffered reading through the new "io" library is now
1852 thread-safe.
1853
Brett Cannonbf3157b2008-08-14 05:00:03 +00001854- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1855 since mimetools itself is deprecated. Because modules are cached, all
1856 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1857
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001858- Issue #3134: shutil referenced undefined WindowsError symbol.
1859
Robert Schuppenies14646332008-08-10 11:01:53 +00001860- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1861 menu entries were not deleted.
1862
Brett Cannon83e81842008-08-09 23:30:55 +00001863- Copied the implementation of reduce() to _functools.reduce() to have a
1864 version that did not raise a DeprecationWarning under -3.
1865
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001866- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1867 a MemoryError rather than silently stop the iteration.
1868
Guido van Rossum59ce9012008-08-09 14:55:34 +00001869- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1870 to _sre.compile() will now be rejected. This should not affect anybody
1871 since the re.compile() function never generates invalid re-bytecode.
1872
Skip Montanaroa032bf42008-08-08 22:52:51 +00001873- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1874 upon first access it can be automatically initialized from the csv file if
1875 it wasn't initialized during instantiation.
1876
Brett Cannon3aa2a492008-08-06 22:28:09 +00001877- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1878 the reload() built-in has been removed.
1879
Brett Cannon7e30b672008-08-04 21:52:25 +00001880- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001881 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001888- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1889 raised an AttributeError.
1890
Benjamin Peterson01a24322008-07-28 23:35:27 +00001891- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001892 asking for a specific length. This problem only affected files opened
1893 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001894
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001895- Issue #3449: Update decimal module to use most recent specification
1896 (v. 1.68) and tests (v. 2.58) from IBM.
1897
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001898- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

1906
1907- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1908 invalid arguments.
1909
1910- Issue #3302: Fix several crashes when calling locale's gettext functions
1911 with None arguments.
1912
1913- Issue #3389: Allow resolving dotted names for handlers in logging
1914 configuration files.
1915
1916- Deprecate the sunaudio module for removal in Python 3.0.
1917
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001918- Issue #3394: zipfile.writestr sets external attributes when passed a
1919 file name rather than a ZipInfo instance, so files are extracted with
1920 mode 0600 rather than 000 under Unix.
1921
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001922- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1923 argument in python 2.5, this broke code that subclassed Popen to include its
1924 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001934- Issue #2235: the C API function PyObject_HashNotImplemented and its
1935 interaction with the tp_hash slot (added in 2.6b2) are now documented
1936
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001937- Issue #643841: The language reference now provides more detailed
1938 coverage of the lookup process for special methods. The disclaimers
1939 regarding lack of coverage of new-style classes have also been
1940 removed, since the coverage is now fairly reasonable.

1949-----------------
1950
Georg Brandl3e483f62008-07-16 22:57:41 +00001951- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1952 its methods now allow for items objects that can be converted to
1953 an integer using operator.index().
1954
Mark Dickinson64b7e502008-07-16 09:40:03 +00001955- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1956 produced a ValueError instead of giving the correct float.
1957
Eric Smitha5fa5a22008-07-16 00:11:49 +00001958- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1959 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1960
Mark Dickinson7103aa42008-07-15 19:08:33 +00001961- Issue #3008: the float type has a new instance method 'float.hex'
1962 and a new class method 'float.fromhex' to convert floating-point
1963 numbers to and from hexadecimal strings, respectively.
1964
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001965- Issue #2235: __hash__ is once again inherited by default. To allow
1966 collections.Hashable to remain meaningful in the presence of the
1967 default hash implementation (object.__hash__), it is now possible
1968 to explicit block inheritance of hash by setting __hash__=None at
1969 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1970 level.
1971
Nick Coghlanb028f502008-07-13 14:52:36 +00001972- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1973 the parent module cannot be found while performing an absolute import.
1974 This means that an incorrectly defined __package__ attribute will
1975 now only prevent relative imports in that module rather than causing
1976 all imports from that module to fail.
1977
Nick Coghlan14ff9942008-07-08 14:21:42 +00001978- Issue #2517: Allow unicode messages in Exceptions again by correctly
1979 bypassing the instance dictionary when looking up __unicode__ on
1980 new-style classes.
1981
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001982- Issue #3242: Fix a crash inside the print statement, if sys.stdout is

1988 another thread's dictionary.
1989
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001990- Issue #3004: Minor change to slice.indices(): the start and stop
1991 arguments are now treated identically, making the behaviour easier
1992 to describe and understand. For example, slice(None, -10,
1993 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1994 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1995 10, -1).
1996
Georg Brandl278fc502008-07-19 12:46:12 +00001997- Issue #3219: Calling a function with repeated keyword arguments,

Georg Brandl5cc774e2008-06-11 20:28:06 +00002449 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002450
2451 This is controlled by the configure argument ``--with-universal-archs``:
2452
2453 - ``--with-universal-archs=all``: install 4-way universal
2454
2455 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2456
2457 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2458

Georg Brandl3ee81df2008-05-17 18:14:43 +00002511- Issue #1631171: Re-implement the 'warnings' module in C (the
2512 original Python code has been kept as backup). This will allow for
2513 using the 'warning's machinery in such places as the parser where
2514 use of pure Python code is not possible. Both the ``showarning()``
2515 and ``formatwarning()`` gain an optional 'line' argument which is
2516 not called by default for backwards-compatibility reasons. Setting
2517 ``warnings.showwarning()`` to an implementation that lacks support
2518 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002573- Issue #2385: distutils.core.run_script() makes __file__ available,
2574 so the controlled environment will more closely mirror the typical
2575 script environment. This supports setup.py scripts that refer to
2576 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002581- Issue #2550: The approach used by client/server code for obtaining
2582 ports to listen on in network-oriented tests has been refined in an
2583 effort to facilitate running multiple instances of the entire
2584 regression test suite in parallel without issue.
2585 test_support.bind_port() has been fixed such that it will always
2586 return a unique port -- which wasn't always the case with the
2587 previous implementation, especially if socket options had been set
2588 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2589 new implementation of bind_port() will actually raise an exception
2590 if it is passed an AF_INET/SOCK_STREAM socket with either the
2591 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2592 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2593 the socket it's been passed. This currently only applies to
2594 Windows. This option prevents any other sockets from binding to the
2595 host/port we've bound to, thus removing the possibility of the
2596 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2597 when a second SOCK_STREAM socket binds and accepts to a host/port
2598 that's already been bound by another socket. The optional preferred
2599 port parameter to bind_port() has been removed. Under no
2600 circumstances should tests be hard coding ports!
2601
2602 test_support.find_unused_port() has also been introduced, which will
2603 pass a temporary socket object to bind_port() in order to obtain an
2604 unused port. The temporary socket object is then closed and
2605 deleted, and the port is returned. This method should only be used
2606 for obtaining an unused port in order to pass to an external program
2607 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2608 a parameter to a server-oriented class that doesn't give you direct
2609 access to the underlying socket used.
2610
2611 Finally, test_support.HOST has been introduced, which should be used
2612 for the host argument of any relevant socket calls (i.e. bind and
2613 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002614
2615 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002616 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002617 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2618 test_asynchat and test_socket_ssl.
2619
Georg Brandl3ee81df2008-05-17 18:14:43 +00002620 It is now possible for multiple instances of the regression test
2621 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002827 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
2828 files are used. On all linux systems the --with-system-ffi
2829 configure option defaults to "yes".

2888-----------------
2889
Fred Drakea8ee94b2008-03-01 02:45:07 +00002890- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002891 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002892
Georg Brandlad61bc82008-02-23 15:11:18 +00002893- Issue #2067: file.__exit__() now calls subclasses' close() method.
2894
2895- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002896
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002897- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002898 issue 215555 for a discussion.
2899
Eric Smitha73fbe72008-02-23 03:09:44 +00002900- Added the future_builtins module, which contains hex() and oct().
2901 These are the PEP 3127 version of these functions, designed to be
2902 compatible with the hex() and oct() builtins from Python 3.0. They
2903 differ slightly in their output formats from the existing, unchanged
2904 Python 2.6 builtins. The expected usage of the future_builtins
2905 module is:
2906 from future_builtins import hex, oct
2907
Eric Smith7ef40bf2008-02-20 23:34:22 +00002908- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2909 exponents for exponents with absolute value < 100. Follows C99
2910 standard. This is a change on Windows, which would use 3 digits.
2911 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2912 so that any alterations it does to the resulting string will be
2913 available in stringlib/formatter.h (for float.__format__).
2914
Eric Smith5a3c1352008-02-19 13:21:56 +00002915- Implemented PEP 3101, Advanced String Formatting. This adds a new
2916 builtin format(); a format() method for str and unicode; a
2917 __format__() method to object, str, unicode, int, long, float, and
2918 datetime; the class string.Formatter; and the C API
2919 PyObject_Format().
2920
Georg Brandl3ee81df2008-05-17 18:14:43 +00002921- Fixed several potential crashes, all caused by specially crafted
2922 __del__ methods exploiting objects in temporarily inconsistent
2923 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002924
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002925- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002926 prevent a possible crash: an Abstract Base Class would try to access
2927 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002928
Georg Brandl3ee81df2008-05-17 18:14:43 +00002929- Fixed repr() and str() of complex numbers with infinity or nan as
2930 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002931
Georg Brandl3ee81df2008-05-17 18:14:43 +00002932- Clear all free lists during a gc.collect() of the highest generation
2933 in order to allow pymalloc to free more arenas. Python may give back
2934 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002935
Georg Brandl3ee81df2008-05-17 18:14:43 +00002936- Issue #2045: Fix an infinite recursion triggered when printing a
2937 subclass of collections.defaultdict, if its default_factory is set
2938 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002939
Christian Heimesf75dbef2008-02-08 00:11:31 +00002940- Fixed a minor memory leak in dictobject.c. The content of the free
2941 list was not freed on interpreter shutdown.
2942
Georg Brandl3ee81df2008-05-17 18:14:43 +00002943- Limit free list of method and builtin function objects to 256
2944 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002945
Georg Brandl3ee81df2008-05-17 18:14:43 +00002946- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2947 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002948 to compact the internal free lists of pre-allocted ints and floats.
2949
Georg Brandl3ee81df2008-05-17 18:14:43 +00002950- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2951 calls. Python expected the return type int but the fork familie
2952 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002953
Georg Brandl3ee81df2008-05-17 18:14:43 +00002954- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2955 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002956
Georg Brandl3ee81df2008-05-17 18:14:43 +00002957- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2958 with the collections.Sequence API.

2964 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002965
Georg Brandl3ee81df2008-05-17 18:14:43 +00002966- Patch #1473257: generator objects gain a gi_code attribute. This is
2967 the same object as the func_code attribute of the function that
2968 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002969
Georg Brandl3ee81df2008-05-17 18:14:43 +00002970- Issue #1920: "while 0" statements were completely removed by the
2971 compiler, even in the presence of an "else" clause, which is
2972 supposed to be run when the condition is false. Now the compiler
2973 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002974
Guido van Rossumeead05f2008-01-24 18:21:02 +00002975- A few crashers fixed: weakref_in_del.py (issue #1377858);
2976 loosing_dict_ref.py (issue #1303614, test67.py);
2977 borrowed_ref_[34].py (not in tracker).
2978
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002979- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002980 suppressed while an extension is loaded by calling SetErrorMode in
2981 dynload_win.c. The error is still reported properly.
2982
Georg Brandl3ee81df2008-05-17 18:14:43 +00002983- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002984 several extension methods and modules do not work without unicode
2985 support.
2986
Georg Brandl26543b12008-01-21 18:36:51 +00002987- Issue #1882: when compiling code from a string, encoding cookies in the
2988 second line of code were not always recognized correctly.
2989
Georg Brandl14404b62008-01-19 19:27:05 +00002990- Issue #1679: "0x" was taken as a valid integer literal.
2991
Georg Brandl6caad7d2008-01-26 14:19:22 +00002992- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002993 added.
2994
Christian Heimesc94e2b52008-01-14 04:13:37 +00002995- sys.float_info / PyFloat_GetInfo: The floating point information
2996 object was converted from a dict to a specialized structseq object.
2997
Georg Brandl3ee81df2008-05-17 18:14:43 +00002998- Patch #1816: Added sys.flags structseq. It exposes the status of
2999 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003000
Georg Brandl3ee81df2008-05-17 18:14:43 +00003001- Objects/structseq.c: Implemented new structseq representation. The
3002 patch makes structseqs (e.g. the return value of os.stat) more
3003 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003004
Georg Brandl3ee81df2008-05-17 18:14:43 +00003005- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00003027 and INF. float("nan"), float("inf") and float("-inf") now work on
3028 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003029
Georg Brandl3ee81df2008-05-17 18:14:43 +00003030- Compiler now generates simpler and faster code for dictionary
3031 literals. The oparg for BUILD_MAP now indicates an estimated
3032 dictionary size. There is a new opcode, STORE_MAP, for adding
3033 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003067- Issue #1265: Fix a problem with sys.settrace, if the tracing
3068 function uses a generator expression when at the same time the
3069 executed code is closing a paused generator.

3074
Neal Norwitz44f326e2007-10-05 05:29:17 +00003075- Fix warnings found by the new version of the Coverity checker.
3076
Georg Brandl3ee81df2008-05-17 18:14:43 +00003077- The enumerate() builtin function is no longer bounded to sequences
3078 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3079 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003080
Georg Brandl3ee81df2008-05-17 18:14:43 +00003081- Issue #1686386: Tuple's tp_repr did not take into account the
3082 possibility of having a self-referential tuple, which is possible
3083 from C code. Nor did object's tp_str consider that a type's tp_str
3084 could do something that could lead to an inifinite recursion.
3085 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3086 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003087
Georg Brandl3ee81df2008-05-17 18:14:43 +00003088- Issue #1164: It was possible to trigger deadlock when using the
3089 'print' statement to write to a file since the GIL was not released
3090 as needed. Now PyObject_Print() does the right thing along with
3091 various tp_print implementations of the built-in types and those in
3092 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003093
Georg Brandl3ee81df2008-05-17 18:14:43 +00003094- Issue #1147: Exceptions were directly allowing string exceptions in
3095 their throw() method even though string exceptions no longer
3096 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003097
Georg Brandl3ee81df2008-05-17 18:14:43 +00003098- Issue #1096: Prevent a segfault from getting the repr of a very
3099 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003100
Brett Cannon1e534b52007-09-07 04:18:30 +00003101- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003102 PyObject_Call() never calling back out to Python code to trigger
3103 recursion depth updates/checks. Required the creation of a static
3104 RuntimeError instance in case normalizing an exception put the
3105 recursion check value past its limit. Fixes crashers
3106 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003107

Neal Norwitz0ac60192007-05-27 04:08:54 +00003121- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003122 __*__ attributes. (Some already existed, e.g., __doc__ and
3123 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003124
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003125- Add -3 option to the interpreter to warn about features that are
3126 deprecated and will be changed/removed in Python 3.0.
3127
Georg Brandl2134e752007-05-21 20:34:16 +00003128- Patch #1686487: you can now pass any mapping after '**' in function
3129 calls.
3130
Collin Winter62903052007-05-18 23:11:24 +00003131- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003132 "except E as target:". This is to provide forwards compatibility
3133 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003134
Brett Cannon229cee22007-05-05 01:34:02 +00003135- Deprecate BaseException.message as per PEP 352.
3136
Georg Brandl3ee81df2008-05-17 18:14:43 +00003137- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003138 inherited from a builtin base.
3139
Vinay Sajip8549ce32007-05-06 17:53:37 +00003140- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003141 setting a plain string, ie don't expand to single letter identifiers.
3142
Raymond Hettinger13936692007-04-11 18:40:58 +00003143- Request #1191699: Slices can now be pickled.
3144
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003145- Request #1193128: str.translate() now allows a None argument for
3146 translations that only remove characters without re-mapping the
3147 remaining characters.
3148
Georg Brandl5cb76c12007-03-21 09:00:39 +00003149- Patch #1682205: a TypeError while unpacking an iterable is no longer

3153
Guido van Rossum143b5642007-03-23 04:58:42 +00003154- Bug #1683368: The object.__init__() and object.__new__() methods are
3155 now stricter in rejecting excess arguments. The only time when
3156 either allows excess arguments is when it is not overridden and the
3157 other one is. For backwards compatibility, when both are
3158 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003159 warning later). Also, type.__init__() insists on the same signature
3160 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003161
Georg Brandl3ee81df2008-05-17 18:14:43 +00003162- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3163 object to complex using its __complex__() method before falling back
3164 to the __float__() method. Therefore, the functions in the cmath
3165 module now can operate on objects that define a __complex__()
3166 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003167
Georg Brandl3ee81df2008-05-17 18:14:43 +00003168- Patch #1623563: allow __class__ assignment for classes with
3169 __slots__. The old and the new class are still required to have the
3170 same slot names.

3176 ``object.__reduce_ex__()`` is called with an object that is faking
3177 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003178
Georg Brandl3ee81df2008-05-17 18:14:43 +00003179- Patch #1680015: Don't modify __slots__ tuple if it contains an

3183
Georg Brandl7b9c5552007-03-12 14:30:05 +00003184- Bug #1678647: write a newline after printing an exception in any
3185 case, even when converting the value to a string failed.
3186
Georg Brandl871f1bc2007-03-12 13:17:36 +00003187- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003188 its argument, if it exists. If not, it will work like before. This
3189 allows customizing the output of dir() in the presence of a
3190 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003191
Collin Winter276887b2007-03-12 16:11:39 +00003192- Patch #922167: Python no longer segfaults when faced with infinitely
3193 self-recursive reload() calls (as reported by bug #742342).
3194

Georg Brandl3ee81df2008-05-17 18:14:43 +00003198- Patch #1491866: change the complex() constructor to allow
3199 parthensized forms. This means complex(repr(x)) now works instead of
3200 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003201
Georg Brandlaa2321b2007-03-07 00:40:28 +00003202- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003203 makes the filenames the warning module prints much more sensible
3204 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003205
Georg Brandl49aafc92007-03-07 00:34:46 +00003206- Variant of patch #697613: don't exit the interpreter on a SystemExit
3207 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003208 variable is given, but break into the interactive interpreter just
3209 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003217- Patch #1674228: when assigning a slice (old-style), check for the
3218 sq_ass_slice instead of the sq_slice slot.
3219
Georg Brandl3ee81df2008-05-17 18:14:43 +00003220- When printing an unraisable error, don't print exceptions. before
3221 the name. This duplicates the behavior whening normally printing
3222 exceptions.

3279
Armin Rigo7ccbca92006-10-04 12:17:45 +00003280- A number of places, including integer negation and absolute value,

Georg Brandl5d59c092006-09-30 08:43:30 +00003287- Patch #1567691: super() and new.instancemethod() now don't accept

3850 -- the failure just occurred later, with a more cumbersome
3851 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004132- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4133 with RFC 3207 and forgets any knowledge obtained from the server not
4134 obtained from the TLS negotiation itself. Patch contributed by Bill
4135 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004136
Georg Brandl3ee81df2008-05-17 18:14:43 +00004137- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004138 that the SMTP.starttls() caller no longer needs to call ehlo()
4139 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004140 does not claim to support starttls. Adds the
4141 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4142 Fenner.

Georg Brandl56112892008-01-20 13:59:46 +00004179- Patch #1648: added ``sys.getprofile()`` and ``sys.gettrace()``.
4180
Georg Brandl3ee81df2008-05-17 18:14:43 +00004181- Patch #1663329: added ``os.closerange()`` function to quickly close

Georg Brandl3ee81df2008-05-17 18:14:43 +00004196- itertools.chain() now has an alternate constructor,

4211 contents before adding elements from the iterable. This fix brings
4212 the behavior into line with that for list.__init__().

4222 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4223 silently miscode subclasses of those types. Now, it raises a
4224 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004225

Georg Brandl3ee81df2008-05-17 18:14:43 +00004240 time so that opening a database previously created with the DB_DUP
4241 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4242 opens. Specifically: dictionary assignment to a DB object will
4243 replace all values for a given key when the database allows
4244 duplicate values. DB users should use DB.put(k, v) when they want
4245 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004246

4252 characters with ASCII value less than 32. Also, it correctly quotes
4253 dots only if they occur on a single line, as opposed to the previous
4254 behavior of quoting dots if they are the second character of any
4255 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004256

4578-----
4579
Georg Brandl3ee81df2008-05-17 18:14:43 +00004580- Unified naming convention for free lists and their limits. All free
4581 lists in Object/ are named ``free_list``, the counter ``numfree``
4582 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4583 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004584
Georg Brandl3ee81df2008-05-17 18:14:43 +00004585- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4586 to ``PyTuple_SetItem``, it can be used to populate a brand new
4587 frozenset; but it does not steal a reference to the added item.

4595- Patch #1720595: add T_BOOL to the range of structmember types.
4596
4597- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4598 ``PyFloat_GetInfo()`` to the float API.
4599
Georg Brandl3ee81df2008-05-17 18:14:43 +00004600- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4601 of w# format code incorrectly truncated the length to an int, even
4602 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4603 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004604
Georg Brandl3ee81df2008-05-17 18:14:43 +00004605- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4606 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004608- PEP 3123: Provide forward compatibility with Python 3.0, while
4609 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4610 and PyVarObject_HEAD_INIT.

4622
4623- Fix some leftovers from the conversion from int to Py_ssize_t
4624 (relevant to strings and sequences of more than 2**31 items).
4625
4626- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4627 outside of pystate.c and should not be necessary.
4628
Georg Brandl3ee81df2008-05-17 18:14:43 +00004629- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4630 absolute imports. In earlier versions they might have used relative
4631 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004632
Georg Brandl3ee81df2008-05-17 18:14:43 +00004633- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4634 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004635
Georg Brandl3ee81df2008-05-17 18:14:43 +00004636- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004643- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4644 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4645 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4646 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004647

Georg Brandl3ee81df2008-05-17 18:14:43 +00004661- Removed the macfs module. It had been deprecated since Python 2.5.
4662 This lead to the deprecation of macostools.touched() as it relied
4663 solely on macfs and was a no-op under OS X.
