1308What's New in Python 2.6.1
1309==========================
1310
1311*Release date: 04-Dec-2008*
1312
1313Core and Builtins
1314-----------------
1315
1316- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1317 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1318 instead of throwing a MemoryError.
1319
1320- Issue #4367: Python would segfault during compiling when the unicodedata
1321 module couldn't be imported and \N escapes were present.
1322
1323- Issue #4348: Some bytearray methods returned that didn't cause any change to
1324 the bytearray, returned the same bytearray instead of a copy.
1325
1326- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1327
1328- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1329
1330- Issue #4048: The parser module now correctly validates relative imports.
1331
1332- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1333 exec statement.

1336 method does not return iterators for the 4th and 5th items.
1337
1338- Issue #4209: Enabling unicode_literals and the print_function in the same
1339 __future__ import didn't work.
1340
1341- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1342 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1343 really executed because I cannot move to such directory on win2k)
1344
1345- Issue #4069: When set.remove(element) is used with a set element, the element
1346 is temporarily replaced with an equivalent frozenset. But the eventual
1347 KeyError would always report the empty frozenset([]) as the missing key. Now
1348 it correctly refers to the initial element.
1349
1350- Fixed C99 style comments in several files. Python is now C89 compatible
1351 again.

1499
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001500- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1501 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1502 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1503 ``printf`` function, whereas PyString_FromFormat has an independent
1504 implementation and uses "%zd" on all platforms for size_t values.
1505 This makes a difference on win64, where ``printf`` needs "%Id" to display
1506 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001508- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Antoine Pitrou0668c622008-08-26 22:42:08 +00001526 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1527 mechanism. In the process, fix a bug where isinstance() and issubclass(),

1529 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1530 type object.

1599
Brett Cannon1eaf0742008-09-02 01:25:16 +00001600- Issue 3602: Moved test.test_support.catch_warning() to
1601 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1602 for catch_warnings() also led to an improvement in the raising of a
1603 DeprecationWarning related to warnings.warn_explicit().
1604
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001605- The deprecation warnings for the old camelCase threading API were removed.

1624
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001625- Issue #2975: When compiling several extension modules with Visual Studio 2008
1626 from the same python interpreter, some environment variables would grow
1627 without limit.
1628
Benjamin Peterson37346b22008-08-23 20:27:43 +00001629- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
1630 exploitation of poor argument checking.
1631
Gerhard Häringef2276b2008-09-12 13:54:06 +00001632- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

1636
Gerhard Häringe6872eb2008-09-12 22:33:22 +00001637- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

1645 wrapper for warnings.catch_warnings() that makes it easier to check
1646 that expected warning messages are being reported.
1647

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001666What's New in Python 2.6 beta 3?
1667================================
1668
Barry Warsaw07a4a382008-08-21 01:15:08 +00001669*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001670
1671Core and Builtins
1672-----------------
1673
Guido van Rossumf8402962008-08-20 15:01:50 +00001674- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1675 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1676 extensions do not automatically benefit from the class attribute
1677 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1678 to their tp_flags field if they care. This is a backwards
1679 compatibility feature; in 3.0, all types will use the cache by
1680 default.
1681
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001682- Keyword arguments can now follow starred arguments. (``f(a, *args,
1683 keyword=23)`` is now valid syntax.)
1684
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001685- ctypes function pointers that are COM methods have a boolean True
1686 value again.
1687
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001688- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1689 by denying s# to parse objects that have a releasebuffer procedure,
1690 and introducing s*.
1691
Georg Brandl1e13ea92008-08-11 09:07:59 +00001692- Issue #3537: Fix an assertion failure when an empty but presized dict
1693 object was stored in the freelist.
1694
Mark Dickinsonb6467572008-08-04 21:30:09 +00001695- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1696 ValueError consistently across platforms.
1697
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001698- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1699 (64bit Unix, for example), unichr() would truncate its argument and return
1700 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1701
Neal Norwitze7d8be82008-07-31 17:17:14 +00001702- Apply security patches from Apple.
1703
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001704- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1705 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1706
Antoine Pitrou92f82162008-07-25 22:22:08 +00001707- Issue #1819: function calls with several named parameters are now on
1708 average 35% faster (as measured by pybench).
1709
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001710- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1711 the python debugger steps into a class statement: the free variables (local
1712 variables defined in an outer scope) would be deleted from the outer scope.
1713
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001714- Issue #2620: Overflow checking when allocating or reallocating memory
1715 was not always being done properly in some python types and extension
1716 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1717 all been updated to perform better checks and places in the code that
1718 would previously leak memory on the error path when such an allocation
1719 failed have been fixed.
1720
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001721Library
1722-------
1723

1725
Benjamin Petersone977ad42008-08-20 01:42:01 +00001726- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1727 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1728
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001729- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1730 version reported by these tools does not necessarily follow the python
1731 version numbering scheme, so the module is less strict when parsing it.
1732
Nick Coghlanf70385a2008-08-18 12:42:46 +00001733- Issue #2235: Added Py3k warnings for types which will become unhashable
1734 under the stricter __hash__ inheritance rules in 3.0. Several types
1735 which did not meet the rules for hash invariants and were already
1736 unhashable in 3.0 have now been explicitly flagged as unhashable in
1737 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1738 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1739
Brett Cannon88f801d2008-08-18 00:46:22 +00001740- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1741 imported into the module but exposed as part of the module's API.
1742
Brett Cannon7b96f072008-08-18 00:41:11 +00001743- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1744
Brett Cannon46225e72008-08-18 00:36:52 +00001745- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001747- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1748
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001749- Issue #3575: Incremental decoder's decode function now takes bytearray
1750 by using 's*' instead of 't#'.
1751
Jesus Cea585ad8a2009-07-02 15:37:21 +00001752- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001753 fails unicode conversion on 2nd parameter. (windows only)
1754
Facundo Batista94f243a2008-08-17 03:38:39 +00001755- Issue 2464. urllib2 now supports a malformation in the URL received
1756 in a redirect.
1757
Brett Cannonabe423e2008-08-16 21:47:07 +00001758- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001759 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001760
Facundo Batistaeb90b782008-08-16 14:44:07 +00001761- Issue #2776: fixed small issue when handling an URL with double slash
1762 after a 302 response in the case of not going through a proxy.
1763
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001764- Issue #2676: in the email package, content-type parsing was hanging on
1765 pathological input because of quadratic or exponential behaviour of a
1766 regular expression.
1767
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001768- Issue #3476: binary buffered reading through the new "io" library is now
1769 thread-safe.
1770
Brett Cannonbf3157b2008-08-14 05:00:03 +00001771- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1772 since mimetools itself is deprecated. Because modules are cached, all
1773 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1774
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001775- Issue #3134: shutil referenced undefined WindowsError symbol.
1776
Robert Schuppenies14646332008-08-10 11:01:53 +00001777- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1778 menu entries were not deleted.
1779
Brett Cannon83e81842008-08-09 23:30:55 +00001780- Copied the implementation of reduce() to _functools.reduce() to have a
1781 version that did not raise a DeprecationWarning under -3.
1782
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001783- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1784 a MemoryError rather than silently stop the iteration.
1785
Guido van Rossum59ce9012008-08-09 14:55:34 +00001786- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1787 to _sre.compile() will now be rejected. This should not affect anybody
1788 since the re.compile() function never generates invalid re-bytecode.
1789
Skip Montanaroa032bf42008-08-08 22:52:51 +00001790- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1791 upon first access it can be automatically initialized from the csv file if
1792 it wasn't initialized during instantiation.

Brett Cannon3aa2a492008-08-06 22:28:09 +00001794- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1795 the reload() built-in has been removed.
1796
Brett Cannon7e30b672008-08-04 21:52:25 +00001797- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001798 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001809 asking for a specific length. This problem only affected files opened
1810 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001811

1837 mode 0600 rather than 000 under Unix.
1838
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001839- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

1870 an integer using operator.index().
1871
Mark Dickinson64b7e502008-07-16 09:40:03 +00001872- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1873 produced a ValueError instead of giving the correct float.
1874
Eric Smitha5fa5a22008-07-16 00:11:49 +00001875- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1876 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1877
Mark Dickinson7103aa42008-07-15 19:08:33 +00001878- Issue #3008: the float type has a new instance method 'float.hex'

1883 collections.Hashable to remain meaningful in the presence of the
1884 default hash implementation (object.__hash__), it is now possible
1885 to explicit block inheritance of hash by setting __hash__=None at
1886 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1887 level.
1888
Nick Coghlanb028f502008-07-13 14:52:36 +00001889- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1890 the parent module cannot be found while performing an absolute import.
1891 This means that an incorrectly defined __package__ attribute will
1892 now only prevent relative imports in that module rather than causing
1893 all imports from that module to fail.
1894
Nick Coghlan14ff9942008-07-08 14:21:42 +00001895- Issue #2517: Allow unicode messages in Exceptions again by correctly

1906
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001907- Issue #3004: Minor change to slice.indices(): the start and stop
1908 arguments are now treated identically, making the behaviour easier
1909 to describe and understand. For example, slice(None, -10,
1910 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1911 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1912 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00001914- Issue #3219: Calling a function with repeated keyword arguments,
1915 f(a=2, a=23), would not cause a syntax error. This was a regression
1916 from 2.4 caused by the switch to the new compiler.

1955 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001956 wrong because the actual transmitted size could differ from the

Georg Brandl5cc774e2008-06-11 20:28:06 +00002366 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002367
2368 This is controlled by the configure argument ``--with-universal-archs``:
2369

2371
2372 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2373
2374 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2375
2376 This option should be used in combination with ``--enable-universalsdk=``.

2415 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00002416
Christian Heimese74c8f22008-04-19 02:23:57 +00002417- Added kill, terminate and send_signal(sig) to subprocess.Popen.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002428- Issue #1631171: Re-implement the 'warnings' module in C (the
2429 original Python code has been kept as backup). This will allow for
2430 using the 'warning's machinery in such places as the parser where
2431 use of pure Python code is not possible. Both the ``showarning()``
2432 and ``formatwarning()`` gain an optional 'line' argument which is
2433 not called by default for backwards-compatibility reasons. Setting
2434 ``warnings.showwarning()`` to an implementation that lacks support
2435 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002498- Issue #2550: The approach used by client/server code for obtaining
2499 ports to listen on in network-oriented tests has been refined in an
2500 effort to facilitate running multiple instances of the entire
2501 regression test suite in parallel without issue.
2502 test_support.bind_port() has been fixed such that it will always
2503 return a unique port -- which wasn't always the case with the
2504 previous implementation, especially if socket options had been set
2505 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2506 new implementation of bind_port() will actually raise an exception
2507 if it is passed an AF_INET/SOCK_STREAM socket with either the
2508 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2509 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2510 the socket it's been passed. This currently only applies to
2511 Windows. This option prevents any other sockets from binding to the
2512 host/port we've bound to, thus removing the possibility of the
2513 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2514 when a second SOCK_STREAM socket binds and accepts to a host/port
2515 that's already been bound by another socket. The optional preferred
2516 port parameter to bind_port() has been removed. Under no
2517 circumstances should tests be hard coding ports!
2518
2519 test_support.find_unused_port() has also been introduced, which will
2520 pass a temporary socket object to bind_port() in order to obtain an
2521 unused port. The temporary socket object is then closed and
2522 deleted, and the port is returned. This method should only be used
2523 for obtaining an unused port in order to pass to an external program
2524 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2525 a parameter to a server-oriented class that doesn't give you direct
2526 access to the underlying socket used.
2527
2528 Finally, test_support.HOST has been introduced, which should be used
2529 for the host argument of any relevant socket calls (i.e. bind and
2530 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002531
2532 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002533 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002534 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2535 test_asynchat and test_socket_ssl.
2536
Georg Brandl3ee81df2008-05-17 18:14:43 +00002537 It is now possible for multiple instances of the regression test
2538 suite to run in parallel without issue.

2805-----------------
2806
Fred Drakea8ee94b2008-03-01 02:45:07 +00002807- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002808 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002809
Georg Brandlad61bc82008-02-23 15:11:18 +00002810- Issue #2067: file.__exit__() now calls subclasses' close() method.
2811
2812- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002813
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002814- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002815 issue 215555 for a discussion.
2816
Eric Smitha73fbe72008-02-23 03:09:44 +00002817- Added the future_builtins module, which contains hex() and oct().
2818 These are the PEP 3127 version of these functions, designed to be
2819 compatible with the hex() and oct() builtins from Python 3.0. They
2820 differ slightly in their output formats from the existing, unchanged
2821 Python 2.6 builtins. The expected usage of the future_builtins
2822 module is:
2823 from future_builtins import hex, oct
2824
Eric Smith7ef40bf2008-02-20 23:34:22 +00002825- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2826 exponents for exponents with absolute value < 100. Follows C99
2827 standard. This is a change on Windows, which would use 3 digits.
2828 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2829 so that any alterations it does to the resulting string will be
2830 available in stringlib/formatter.h (for float.__format__).
2831
Eric Smith5a3c1352008-02-19 13:21:56 +00002832- Implemented PEP 3101, Advanced String Formatting. This adds a new
2833 builtin format(); a format() method for str and unicode; a
2834 __format__() method to object, str, unicode, int, long, float, and
2835 datetime; the class string.Formatter; and the C API
2836 PyObject_Format().
2837
Georg Brandl3ee81df2008-05-17 18:14:43 +00002838- Fixed several potential crashes, all caused by specially crafted
2839 __del__ methods exploiting objects in temporarily inconsistent
2840 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002841
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002842- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002843 prevent a possible crash: an Abstract Base Class would try to access
2844 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002845
Georg Brandl3ee81df2008-05-17 18:14:43 +00002846- Fixed repr() and str() of complex numbers with infinity or nan as
2847 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002848
Georg Brandl3ee81df2008-05-17 18:14:43 +00002849- Clear all free lists during a gc.collect() of the highest generation
2850 in order to allow pymalloc to free more arenas. Python may give back
2851 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002852
Georg Brandl3ee81df2008-05-17 18:14:43 +00002853- Issue #2045: Fix an infinite recursion triggered when printing a
2854 subclass of collections.defaultdict, if its default_factory is set
2855 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002856
Christian Heimesf75dbef2008-02-08 00:11:31 +00002857- Fixed a minor memory leak in dictobject.c. The content of the free
2858 list was not freed on interpreter shutdown.
2859
Georg Brandl5a7eca12010-03-21 19:29:04 +00002860- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00002861 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002862
Georg Brandl3ee81df2008-05-17 18:14:43 +00002863- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2864 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002865 to compact the internal free lists of pre-allocted ints and floats.
2866
Georg Brandl3ee81df2008-05-17 18:14:43 +00002867- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2868 calls. Python expected the return type int but the fork familie
2869 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002870
Georg Brandl3ee81df2008-05-17 18:14:43 +00002871- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2872 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002873
Georg Brandl3ee81df2008-05-17 18:14:43 +00002874- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2875 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002876
Georg Brandl3ee81df2008-05-17 18:14:43 +00002877- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2878 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00002880- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2881 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002882
Georg Brandl3ee81df2008-05-17 18:14:43 +00002883- Patch #1473257: generator objects gain a gi_code attribute. This is
2884 the same object as the func_code attribute of the function that
2885 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002886
Georg Brandl3ee81df2008-05-17 18:14:43 +00002887- Issue #1920: "while 0" statements were completely removed by the
2888 compiler, even in the presence of an "else" clause, which is
2889 supposed to be run when the condition is false. Now the compiler
2890 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002891
Guido van Rossumeead05f2008-01-24 18:21:02 +00002892- A few crashers fixed: weakref_in_del.py (issue #1377858);
2893 loosing_dict_ref.py (issue #1303614, test67.py);
2894 borrowed_ref_[34].py (not in tracker).
2895
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002896- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002897 suppressed while an extension is loaded by calling SetErrorMode in
2898 dynload_win.c. The error is still reported properly.
2899
Georg Brandl3ee81df2008-05-17 18:14:43 +00002900- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002901 several extension methods and modules do not work without unicode
2902 support.
2903
Georg Brandl26543b12008-01-21 18:36:51 +00002904- Issue #1882: when compiling code from a string, encoding cookies in the
2905 second line of code were not always recognized correctly.
2906
Georg Brandl14404b62008-01-19 19:27:05 +00002907- Issue #1679: "0x" was taken as a valid integer literal.
2908
Georg Brandl6caad7d2008-01-26 14:19:22 +00002909- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002910 added.
2911
Christian Heimesc94e2b52008-01-14 04:13:37 +00002912- sys.float_info / PyFloat_GetInfo: The floating point information
2913 object was converted from a dict to a specialized structseq object.
2914
Georg Brandl3ee81df2008-05-17 18:14:43 +00002915- Patch #1816: Added sys.flags structseq. It exposes the status of
2916 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002917
Georg Brandl3ee81df2008-05-17 18:14:43 +00002918- Objects/structseq.c: Implemented new structseq representation. The
2919 patch makes structseqs (e.g. the return value of os.stat) more
2920 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002921
Georg Brandl3ee81df2008-05-17 18:14:43 +00002922- Patch #1700288: added a type attribute cache that caches method
2923 accesses, resulting in speedups in heavily object-oriented code.

2931 envvar and sys.dont_write_bytecode attribute. All these can be set
2932 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002933
Georg Brandl3ee81df2008-05-17 18:14:43 +00002934- Improve some exception messages when Windows fails to load an
2935 extension module. Now we get for example '%1 is not a valid Win32
2936 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002937

2941 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002942
Christian Heimes0a8143f2007-12-18 23:22:54 +00002943- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002944 and INF. float("nan"), float("inf") and float("-inf") now work on
2945 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002946
Georg Brandl3ee81df2008-05-17 18:14:43 +00002947- Compiler now generates simpler and faster code for dictionary

Georg Brandl3ee81df2008-05-17 18:14:43 +00002998- Issue #1686386: Tuple's tp_repr did not take into account the
2999 possibility of having a self-referential tuple, which is possible
3000 from C code. Nor did object's tp_str consider that a type's tp_str
3001 could do something that could lead to an inifinite recursion.
3002 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3003 issues.

3070
Guido van Rossum143b5642007-03-23 04:58:42 +00003071- Bug #1683368: The object.__init__() and object.__new__() methods are
3072 now stricter in rejecting excess arguments. The only time when
3073 either allows excess arguments is when it is not overridden and the
3074 other one is. For backwards compatibility, when both are
3075 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003076 warning later). Also, type.__init__() insists on the same signature
3077 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003079- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3080 object to complex using its __complex__() method before falling back
3081 to the __float__() method. Therefore, the functions in the cmath
3082 module now can operate on objects that define a __complex__()
3083 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00003101- Bug #1678647: write a newline after printing an exception in any
3102 case, even when converting the value to a string failed.
3103
Georg Brandl871f1bc2007-03-12 13:17:36 +00003104- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003105 its argument, if it exists. If not, it will work like before. This
3106 allows customizing the output of dir() in the presence of a
3107 __getattr__().

3117 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003118
Georg Brandlaa2321b2007-03-07 00:40:28 +00003119- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003120 makes the filenames the warning module prints much more sensible
3121 when a PYTHONSTARTUP file is used.

3136
Georg Brandl3ee81df2008-05-17 18:14:43 +00003137- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00003218- Bug #1551432: Exceptions do not define an explicit __unicode__
3219 method. This allows calling unicode() on exceptions classes
3220 directly to succeed.
Brett Cannon9adeab72006-09-20 18:34:28 +00003221
Georg Brandl4e933132006-09-06 20:05:58 +00003222- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003240 generator expressions (x for x, in ... ) works again. Fixing this
3241 problem required changing the .pyc magic number. This means that
3242 .pyc files generated before 2.5c2 will be regenerated.

Guido van Rossum8bc09652008-02-21 18:18:37 +00003281- Removed uses of dict.has_key() from distutils, and uses of
3282 callable() from copy_reg.py, so the interpreter now starts up

Georg Brandl3ee81df2008-05-17 18:14:43 +00003690- Patch #1530482: add pydoc.render_doc() which returns the

3705
Georg Brandl92a6bae2007-03-13 17:43:32 +00003706- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003707 are set for invalid interpolation sequences that would lead to
3708 errors on reading back those values.

3764 TestCase and TestSuite subclasses (not instances) are no longer
3765 accepted in TestSuite.addTest(). This should cause no
3766 incompatibility since it never made sense with ordinary subclasses
3767 -- the failure just occurred later, with a more cumbersome
3768 exception.

4050 with RFC 3207 and forgets any knowledge obtained from the server not
4051 obtained from the TLS negotiation itself. Patch contributed by Bill
4052 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004053
Georg Brandl3ee81df2008-05-17 18:14:43 +00004054- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004055 that the SMTP.starttls() caller no longer needs to call ehlo()
4056 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004057 does not claim to support starttls. Adds the
4058 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4139 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4140 silently miscode subclasses of those types. Now, it raises a

Raymond Hettinger12e94202007-11-07 01:13:09 +00004142

Georg Brandl3ee81df2008-05-17 18:14:43 +00004157 time so that opening a database previously created with the DB_DUP
4158 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4159 opens. Specifically: dictionary assignment to a DB object will
4160 replace all values for a given key when the database allows

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004441- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00004442 periodic threadstate and signal checking in tight loops. By
4443 default, this option is turned-off. It should only be enabled in
4444 debugged, performance critical applications.

4500 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004501
Georg Brandl3ee81df2008-05-17 18:14:43 +00004502- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4503 to ``PyTuple_SetItem``, it can be used to populate a brand new
4504 frozenset; but it does not steal a reference to the added item.

4516
Georg Brandl3ee81df2008-05-17 18:14:43 +00004517- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4518 of w# format code incorrectly truncated the length to an int, even
4519 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4520 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004521

Georg Brandl3ee81df2008-05-17 18:14:43 +00004550- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4551 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004552
Georg Brandl3ee81df2008-05-17 18:14:43 +00004553- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
