1305==========================
1306
1307*Release date: 04-Dec-2008*
1308
1309Core and Builtins
1310-----------------
1311
1312- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1313 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1314 instead of throwing a MemoryError.
1315
1316- Issue #4367: Python would segfault during compiling when the unicodedata
1317 module couldn't be imported and \N escapes were present.
1318
1319- Issue #4348: Some bytearray methods returned that didn't cause any change to
1320 the bytearray, returned the same bytearray instead of a copy.
1321
1322- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1323
1324- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1325
1326- Issue #4048: The parser module now correctly validates relative imports.
1327
1328- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

1332 method does not return iterators for the 4th and 5th items.
1333
1334- Issue #4209: Enabling unicode_literals and the print_function in the same
1335 __future__ import didn't work.
1336
1337- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1338 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1339 really executed because I cannot move to such directory on win2k)
1340
1341- Issue #4069: When set.remove(element) is used with a set element, the element
1342 is temporarily replaced with an equivalent frozenset. But the eventual
1343 KeyError would always report the empty frozenset([]) as the missing key. Now
1344 it correctly refers to the initial element.
1345
1346- Fixed C99 style comments in several files. Python is now C89 compatible
1347 again.

1495
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001496- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1497 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1498 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1499 ``printf`` function, whereas PyString_FromFormat has an independent
1500 implementation and uses "%zd" on all platforms for size_t values.
1501 This makes a difference on win64, where ``printf`` needs "%Id" to display
1502 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00001522 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1523 mechanism. In the process, fix a bug where isinstance() and issubclass(),

1525 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1526 type object.

1595
Brett Cannon1eaf0742008-09-02 01:25:16 +00001596- Issue 3602: Moved test.test_support.catch_warning() to
1597 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1598 for catch_warnings() also led to an improvement in the raising of a
1599 DeprecationWarning related to warnings.warn_explicit().
1600
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001601- The deprecation warnings for the old camelCase threading API were removed.

1620
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001621- Issue #2975: When compiling several extension modules with Visual Studio 2008
1622 from the same python interpreter, some environment variables would grow
1623 without limit.
1624
Benjamin Peterson37346b22008-08-23 20:27:43 +00001625- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

1641 wrapper for warnings.catch_warnings() that makes it easier to check
1642 that expected warning messages are being reported.
1643

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001662What's New in Python 2.6 beta 3?
1663================================
1664
Barry Warsaw07a4a382008-08-21 01:15:08 +00001665*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001666
1667Core and Builtins
1668-----------------
1669
Guido van Rossumf8402962008-08-20 15:01:50 +00001670- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1671 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1672 extensions do not automatically benefit from the class attribute
1673 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1674 to their tp_flags field if they care. This is a backwards
1675 compatibility feature; in 3.0, all types will use the cache by
1676 default.
1677
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001678- Keyword arguments can now follow starred arguments. (``f(a, *args,
1679 keyword=23)`` is now valid syntax.)
1680
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001681- ctypes function pointers that are COM methods have a boolean True
1682 value again.
1683
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001684- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1685 by denying s# to parse objects that have a releasebuffer procedure,
1686 and introducing s*.
1687
Georg Brandl1e13ea92008-08-11 09:07:59 +00001688- Issue #3537: Fix an assertion failure when an empty but presized dict
1689 object was stored in the freelist.
1690
Mark Dickinsonb6467572008-08-04 21:30:09 +00001691- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1692 ValueError consistently across platforms.
1693
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001694- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1695 (64bit Unix, for example), unichr() would truncate its argument and return
1696 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1697
Neal Norwitze7d8be82008-07-31 17:17:14 +00001698- Apply security patches from Apple.
1699
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001700- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1701 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1702
Antoine Pitrou92f82162008-07-25 22:22:08 +00001703- Issue #1819: function calls with several named parameters are now on
1704 average 35% faster (as measured by pybench).
1705
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001706- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1707 the python debugger steps into a class statement: the free variables (local
1708 variables defined in an outer scope) would be deleted from the outer scope.
1709
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001710- Issue #2620: Overflow checking when allocating or reallocating memory
1711 was not always being done properly in some python types and extension
1712 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1713 all been updated to perform better checks and places in the code that
1714 would previously leak memory on the error path when such an allocation
1715 failed have been fixed.
1716
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001717Library
1718-------
1719

1721
Benjamin Petersone977ad42008-08-20 01:42:01 +00001722- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1723 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1724
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001725- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1726 version reported by these tools does not necessarily follow the python
1727 version numbering scheme, so the module is less strict when parsing it.
1728
Nick Coghlanf70385a2008-08-18 12:42:46 +00001729- Issue #2235: Added Py3k warnings for types which will become unhashable
1730 under the stricter __hash__ inheritance rules in 3.0. Several types
1731 which did not meet the rules for hash invariants and were already
1732 unhashable in 3.0 have now been explicitly flagged as unhashable in
1733 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1734 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1735
Brett Cannon88f801d2008-08-18 00:46:22 +00001736- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1737 imported into the module but exposed as part of the module's API.
1738

1740
Brett Cannon46225e72008-08-18 00:36:52 +00001741- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

1744
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001745- Issue #3575: Incremental decoder's decode function now takes bytearray
1746 by using 's*' instead of 't#'.
1747
Jesus Cea585ad8a2009-07-02 15:37:21 +00001748- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001749 fails unicode conversion on 2nd parameter. (windows only)
1750
Facundo Batista94f243a2008-08-17 03:38:39 +00001751- Issue 2464. urllib2 now supports a malformation in the URL received
1752 in a redirect.
1753
Brett Cannonabe423e2008-08-16 21:47:07 +00001754- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001755 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001756
Facundo Batistaeb90b782008-08-16 14:44:07 +00001757- Issue #2776: fixed small issue when handling an URL with double slash
1758 after a 302 response in the case of not going through a proxy.
1759
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001760- Issue #2676: in the email package, content-type parsing was hanging on
1761 pathological input because of quadratic or exponential behaviour of a
1762 regular expression.
1763
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001764- Issue #3476: binary buffered reading through the new "io" library is now
1765 thread-safe.
1766
Brett Cannonbf3157b2008-08-14 05:00:03 +00001767- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1768 since mimetools itself is deprecated. Because modules are cached, all
1769 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1770
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001771- Issue #3134: shutil referenced undefined WindowsError symbol.
1772
Robert Schuppenies14646332008-08-10 11:01:53 +00001773- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1774 menu entries were not deleted.
1775
Brett Cannon83e81842008-08-09 23:30:55 +00001776- Copied the implementation of reduce() to _functools.reduce() to have a
1777 version that did not raise a DeprecationWarning under -3.
1778
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001779- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1780 a MemoryError rather than silently stop the iteration.
1781
Guido van Rossum59ce9012008-08-09 14:55:34 +00001782- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1783 to _sre.compile() will now be rejected. This should not affect anybody
1784 since the re.compile() function never generates invalid re-bytecode.
1785
Skip Montanaroa032bf42008-08-08 22:52:51 +00001786- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Brett Cannon3aa2a492008-08-06 22:28:09 +00001790- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1791 the reload() built-in has been removed.
1792
Brett Cannon7e30b672008-08-04 21:52:25 +00001793- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001794 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001805 asking for a specific length. This problem only affected files opened
1806 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001807

1833 mode 0600 rather than 000 under Unix.
1834
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001835- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

1867
Mark Dickinson64b7e502008-07-16 09:40:03 +00001868- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1869 produced a ValueError instead of giving the correct float.
1870
Eric Smitha5fa5a22008-07-16 00:11:49 +00001871- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1872 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1873
Mark Dickinson7103aa42008-07-15 19:08:33 +00001874- Issue #3008: the float type has a new instance method 'float.hex'

1879 collections.Hashable to remain meaningful in the presence of the
1880 default hash implementation (object.__hash__), it is now possible
1881 to explicit block inheritance of hash by setting __hash__=None at
1882 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1883 level.
1884
Nick Coghlanb028f502008-07-13 14:52:36 +00001885- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1886 the parent module cannot be found while performing an absolute import.
1887 This means that an incorrectly defined __package__ attribute will
1888 now only prevent relative imports in that module rather than causing
1889 all imports from that module to fail.

Nick Coghlan14ff9942008-07-08 14:21:42 +00001891- Issue #2517: Allow unicode messages in Exceptions again by correctly

1902
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001903- Issue #3004: Minor change to slice.indices(): the start and stop
1904 arguments are now treated identically, making the behaviour easier
1905 to describe and understand. For example, slice(None, -10,
1906 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1907 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1908 10, -1).

1911 f(a=2, a=23), would not cause a syntax error. This was a regression
1912 from 2.4 caused by the switch to the new compiler.

1951 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001952 wrong because the actual transmitted size could differ from the

Georg Brandl5cc774e2008-06-11 20:28:06 +00002362 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002363
2364 This is controlled by the configure argument ``--with-universal-archs``:
2365

2367
2368 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2369
2370 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2371
2372 This option should be used in combination with ``--enable-universalsdk=``.

2411 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00002412
Christian Heimese74c8f22008-04-19 02:23:57 +00002413- Added kill, terminate and send_signal(sig) to subprocess.Popen.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002424- Issue #1631171: Re-implement the 'warnings' module in C (the
2425 original Python code has been kept as backup). This will allow for
2426 using the 'warning's machinery in such places as the parser where
2427 use of pure Python code is not possible. Both the ``showarning()``
2428 and ``formatwarning()`` gain an optional 'line' argument which is
2429 not called by default for backwards-compatibility reasons. Setting
2430 ``warnings.showwarning()`` to an implementation that lacks support
2431 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002494- Issue #2550: The approach used by client/server code for obtaining
2495 ports to listen on in network-oriented tests has been refined in an
2496 effort to facilitate running multiple instances of the entire
2497 regression test suite in parallel without issue.
2498 test_support.bind_port() has been fixed such that it will always
2499 return a unique port -- which wasn't always the case with the
2500 previous implementation, especially if socket options had been set
2501 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2502 new implementation of bind_port() will actually raise an exception
2503 if it is passed an AF_INET/SOCK_STREAM socket with either the
2504 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2505 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2506 the socket it's been passed. This currently only applies to
2507 Windows. This option prevents any other sockets from binding to the
2508 host/port we've bound to, thus removing the possibility of the
2509 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2510 when a second SOCK_STREAM socket binds and accepts to a host/port
2511 that's already been bound by another socket. The optional preferred
2512 port parameter to bind_port() has been removed. Under no
2513 circumstances should tests be hard coding ports!
2514
2515 test_support.find_unused_port() has also been introduced, which will
2516 pass a temporary socket object to bind_port() in order to obtain an
2517 unused port. The temporary socket object is then closed and
2518 deleted, and the port is returned. This method should only be used
2519 for obtaining an unused port in order to pass to an external program
2520 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2521 a parameter to a server-oriented class that doesn't give you direct
2522 access to the underlying socket used.
2523
2524 Finally, test_support.HOST has been introduced, which should be used
2525 for the host argument of any relevant socket calls (i.e. bind and
2526 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002527
2528 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002529 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002530 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2531 test_asynchat and test_socket_ssl.
2532
Georg Brandl3ee81df2008-05-17 18:14:43 +00002533 It is now possible for multiple instances of the regression test
2534 suite to run in parallel without issue.

2801-----------------
2802
Fred Drakea8ee94b2008-03-01 02:45:07 +00002803- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002804 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002805
Georg Brandlad61bc82008-02-23 15:11:18 +00002806- Issue #2067: file.__exit__() now calls subclasses' close() method.
2807
2808- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002809
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002810- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002811 issue 215555 for a discussion.
2812
Eric Smitha73fbe72008-02-23 03:09:44 +00002813- Added the future_builtins module, which contains hex() and oct().
2814 These are the PEP 3127 version of these functions, designed to be
2815 compatible with the hex() and oct() builtins from Python 3.0. They
2816 differ slightly in their output formats from the existing, unchanged
2817 Python 2.6 builtins. The expected usage of the future_builtins
2818 module is:
2819 from future_builtins import hex, oct
2820
Eric Smith7ef40bf2008-02-20 23:34:22 +00002821- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2822 exponents for exponents with absolute value < 100. Follows C99
2823 standard. This is a change on Windows, which would use 3 digits.
2824 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2825 so that any alterations it does to the resulting string will be
2826 available in stringlib/formatter.h (for float.__format__).
2827
Eric Smith5a3c1352008-02-19 13:21:56 +00002828- Implemented PEP 3101, Advanced String Formatting. This adds a new
2829 builtin format(); a format() method for str and unicode; a
2830 __format__() method to object, str, unicode, int, long, float, and
2831 datetime; the class string.Formatter; and the C API
2832 PyObject_Format().
2833
Georg Brandl3ee81df2008-05-17 18:14:43 +00002834- Fixed several potential crashes, all caused by specially crafted
2835 __del__ methods exploiting objects in temporarily inconsistent
2836 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002837
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002838- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002839 prevent a possible crash: an Abstract Base Class would try to access
2840 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002841
Georg Brandl3ee81df2008-05-17 18:14:43 +00002842- Fixed repr() and str() of complex numbers with infinity or nan as
2843 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002844
Georg Brandl3ee81df2008-05-17 18:14:43 +00002845- Clear all free lists during a gc.collect() of the highest generation
2846 in order to allow pymalloc to free more arenas. Python may give back
2847 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002848
Georg Brandl3ee81df2008-05-17 18:14:43 +00002849- Issue #2045: Fix an infinite recursion triggered when printing a
2850 subclass of collections.defaultdict, if its default_factory is set
2851 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002852
Christian Heimesf75dbef2008-02-08 00:11:31 +00002853- Fixed a minor memory leak in dictobject.c. The content of the free
2854 list was not freed on interpreter shutdown.
2855
Georg Brandl5a7eca12010-03-21 19:29:04 +00002856- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00002857 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002858
Georg Brandl3ee81df2008-05-17 18:14:43 +00002859- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2860 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002861 to compact the internal free lists of pre-allocted ints and floats.
2862
Georg Brandl3ee81df2008-05-17 18:14:43 +00002863- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2864 calls. Python expected the return type int but the fork familie
2865 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002866
Georg Brandl3ee81df2008-05-17 18:14:43 +00002867- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2868 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002869
Georg Brandl3ee81df2008-05-17 18:14:43 +00002870- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2871 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002872
Georg Brandl3ee81df2008-05-17 18:14:43 +00002873- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2874 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00002876- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2877 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002878
Georg Brandl3ee81df2008-05-17 18:14:43 +00002879- Patch #1473257: generator objects gain a gi_code attribute. This is
2880 the same object as the func_code attribute of the function that
2881 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002882
Georg Brandl3ee81df2008-05-17 18:14:43 +00002883- Issue #1920: "while 0" statements were completely removed by the
2884 compiler, even in the presence of an "else" clause, which is
2885 supposed to be run when the condition is false. Now the compiler
2886 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002887
Guido van Rossumeead05f2008-01-24 18:21:02 +00002888- A few crashers fixed: weakref_in_del.py (issue #1377858);
2889 loosing_dict_ref.py (issue #1303614, test67.py);
2890 borrowed_ref_[34].py (not in tracker).
2891
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002892- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002893 suppressed while an extension is loaded by calling SetErrorMode in
2894 dynload_win.c. The error is still reported properly.
2895
Georg Brandl3ee81df2008-05-17 18:14:43 +00002896- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002897 several extension methods and modules do not work without unicode
2898 support.
2899
Georg Brandl26543b12008-01-21 18:36:51 +00002900- Issue #1882: when compiling code from a string, encoding cookies in the
2901 second line of code were not always recognized correctly.
2902
Georg Brandl14404b62008-01-19 19:27:05 +00002903- Issue #1679: "0x" was taken as a valid integer literal.
2904
Georg Brandl6caad7d2008-01-26 14:19:22 +00002905- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002906 added.
2907
Christian Heimesc94e2b52008-01-14 04:13:37 +00002908- sys.float_info / PyFloat_GetInfo: The floating point information
2909 object was converted from a dict to a specialized structseq object.
2910
Georg Brandl3ee81df2008-05-17 18:14:43 +00002911- Patch #1816: Added sys.flags structseq. It exposes the status of
2912 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002913
Georg Brandl3ee81df2008-05-17 18:14:43 +00002914- Objects/structseq.c: Implemented new structseq representation. The
2915 patch makes structseqs (e.g. the return value of os.stat) more
2916 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002917
Georg Brandl3ee81df2008-05-17 18:14:43 +00002918- Patch #1700288: added a type attribute cache that caches method
2919 accesses, resulting in speedups in heavily object-oriented code.

2927 envvar and sys.dont_write_bytecode attribute. All these can be set
2928 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002929
Georg Brandl3ee81df2008-05-17 18:14:43 +00002930- Improve some exception messages when Windows fails to load an
2931 extension module. Now we get for example '%1 is not a valid Win32
2932 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002933

2937 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002938
Christian Heimes0a8143f2007-12-18 23:22:54 +00002939- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002940 and INF. float("nan"), float("inf") and float("-inf") now work on
2941 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002942
Georg Brandl3ee81df2008-05-17 18:14:43 +00002943- Compiler now generates simpler and faster code for dictionary

Georg Brandl3ee81df2008-05-17 18:14:43 +00002994- Issue #1686386: Tuple's tp_repr did not take into account the
2995 possibility of having a self-referential tuple, which is possible
2996 from C code. Nor did object's tp_str consider that a type's tp_str
2997 could do something that could lead to an inifinite recursion.
2998 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2999 issues.

3066
Guido van Rossum143b5642007-03-23 04:58:42 +00003067- Bug #1683368: The object.__init__() and object.__new__() methods are
3068 now stricter in rejecting excess arguments. The only time when
3069 either allows excess arguments is when it is not overridden and the
3070 other one is. For backwards compatibility, when both are
3071 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003072 warning later). Also, type.__init__() insists on the same signature
3073 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003075- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3076 object to complex using its __complex__() method before falling back
3077 to the __float__() method. Therefore, the functions in the cmath
3078 module now can operate on objects that define a __complex__()
3079 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00003097- Bug #1678647: write a newline after printing an exception in any
3098 case, even when converting the value to a string failed.
3099
Georg Brandl871f1bc2007-03-12 13:17:36 +00003100- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003101 its argument, if it exists. If not, it will work like before. This
3102 allows customizing the output of dir() in the presence of a
3103 __getattr__().

3113 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003114
Georg Brandlaa2321b2007-03-07 00:40:28 +00003115- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003116 makes the filenames the warning module prints much more sensible
3117 when a PYTHONSTARTUP file is used.

3132
Georg Brandl3ee81df2008-05-17 18:14:43 +00003133- When printing an unraisable error, don't print exceptions. before

3215 method. This allows calling unicode() on exceptions classes
3216 directly to succeed.
Brett Cannon9adeab72006-09-20 18:34:28 +00003217
Georg Brandl4e933132006-09-06 20:05:58 +00003218- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003236 generator expressions (x for x, in ... ) works again. Fixing this
3237 problem required changing the .pyc magic number. This means that
3238 .pyc files generated before 2.5c2 will be regenerated.

Guido van Rossum8bc09652008-02-21 18:18:37 +00003277- Removed uses of dict.has_key() from distutils, and uses of
3278 callable() from copy_reg.py, so the interpreter now starts up

3701
Georg Brandl92a6bae2007-03-13 17:43:32 +00003702- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003703 are set for invalid interpolation sequences that would lead to
3704 errors on reading back those values.

3760 TestCase and TestSuite subclasses (not instances) are no longer
3761 accepted in TestSuite.addTest(). This should cause no

3763 -- the failure just occurred later, with a more cumbersome
3764 exception.

4048 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004049
Georg Brandl3ee81df2008-05-17 18:14:43 +00004050- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004051 that the SMTP.starttls() caller no longer needs to call ehlo()
4052 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004053 does not claim to support starttls. Adds the
4054 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00004153 time so that opening a database previously created with the DB_DUP
4154 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4155 opens. Specifically: dictionary assignment to a DB object will
4156 replace all values for a given key when the database allows

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004437- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00004438 periodic threadstate and signal checking in tight loops. By
4439 default, this option is turned-off. It should only be enabled in
4440 debugged, performance critical applications.

4492
Georg Brandl3ee81df2008-05-17 18:14:43 +00004493- Unified naming convention for free lists and their limits. All free
4494 lists in Object/ are named ``free_list``, the counter ``numfree``
4495 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4496 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004497
Georg Brandl3ee81df2008-05-17 18:14:43 +00004498- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4499 to ``PyTuple_SetItem``, it can be used to populate a brand new
4500 frozenset; but it does not steal a reference to the added item.

4512
Georg Brandl3ee81df2008-05-17 18:14:43 +00004513- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4514 of w# format code incorrectly truncated the length to an int, even
4515 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4516 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004517

4538
4539- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4540 outside of pystate.c and should not be necessary.
4541
Georg Brandl3ee81df2008-05-17 18:14:43 +00004542- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4543 absolute imports. In earlier versions they might have used relative
4544 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004545
Georg Brandl3ee81df2008-05-17 18:14:43 +00004546- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4547 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004548
Georg Brandl3ee81df2008-05-17 18:14:43 +00004549- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004574- Removed the macfs module. It had been deprecated since Python 2.5.
4575 This lead to the deprecation of macostools.touched() as it relied
