1274What's New in Python 2.6.1
1275==========================
1276
1277*Release date: 04-Dec-2008*
1278
1279Core and Builtins
1280-----------------
1281
1282- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1283 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1284 instead of throwing a MemoryError.
1285
1286- Issue #4367: Python would segfault during compiling when the unicodedata
1287 module couldn't be imported and \N escapes were present.
1288
1289- Issue #4348: Some bytearray methods returned that didn't cause any change to
1290 the bytearray, returned the same bytearray instead of a copy.
1291
1292- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1293
1294- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1295
1296- Issue #4048: The parser module now correctly validates relative imports.
1297
1298- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1299 exec statement.
1300
1301- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1302 method does not return iterators for the 4th and 5th items.
1303
1304- Issue #4209: Enabling unicode_literals and the print_function in the same
1305 __future__ import didn't work.
1306
1307- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1308 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1309 really executed because I cannot move to such directory on win2k)
1310
1311- Issue #4069: When set.remove(element) is used with a set element, the element
1312 is temporarily replaced with an equivalent frozenset. But the eventual
1313 KeyError would always report the empty frozenset([]) as the missing key. Now
1314 it correctly refers to the initial element.
1315
1316- Fixed C99 style comments in several files. Python is now C89 compatible
1317 again.

1465
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001466- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1467 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1468 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1469 ``printf`` function, whereas PyString_FromFormat has an independent
1470 implementation and uses "%zd" on all platforms for size_t values.
1471 This makes a difference on win64, where ``printf`` needs "%Id" to display
1472 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001474- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Vinay Sajip35e3b032008-09-01 14:33:59 +00001491- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001492 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1493 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1494 when given a tuple of classes as second argument, were looking up
1495 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1496 type object.

1589-----------------
1590
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001591- Issue #2975: When compiling several extension modules with Visual Studio 2008
1592 from the same python interpreter, some environment variables would grow
1593 without limit.
1594
Benjamin Peterson37346b22008-08-23 20:27:43 +00001595- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
1596 exploitation of poor argument checking.
1597
Gerhard Häringef2276b2008-09-12 13:54:06 +00001598- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
1599
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00001600- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
1601 remaining ones have "pysqlite_" prefix.
1602
Gerhard Häringe6872eb2008-09-12 22:33:22 +00001603- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

1609
Nick Coghland2e09382008-09-11 12:11:06 +00001610- Issue #3781: Add test.test_support.check_warnings() as a convenience
1611 wrapper for warnings.catch_warnings() that makes it easier to check
1612 that expected warning messages are being reported.
1613
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00001614- Issue #3796: Some tests functions were not enabled in test_float.
1615

Martin v. Löwisab0b29b2008-09-13 08:11:57 +00001621- Issue #3833: Use a different upgrade code for Win64 installers.
1622
Martin v. Löwis3f5fda82008-09-08 13:50:10 +00001623- Issue #2271: Set SecureCustomProperties so that installation will properly

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001632What's New in Python 2.6 beta 3?
1633================================
1634
Barry Warsaw07a4a382008-08-21 01:15:08 +00001635*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001636
1637Core and Builtins
1638-----------------
1639
Guido van Rossumf8402962008-08-20 15:01:50 +00001640- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1641 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1642 extensions do not automatically benefit from the class attribute
1643 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1644 to their tp_flags field if they care. This is a backwards
1645 compatibility feature; in 3.0, all types will use the cache by
1646 default.
1647
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001648- Keyword arguments can now follow starred arguments. (``f(a, *args,
1649 keyword=23)`` is now valid syntax.)
1650
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001651- ctypes function pointers that are COM methods have a boolean True
1652 value again.
1653
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001654- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1655 by denying s# to parse objects that have a releasebuffer procedure,
1656 and introducing s*.
1657
Georg Brandl1e13ea92008-08-11 09:07:59 +00001658- Issue #3537: Fix an assertion failure when an empty but presized dict
1659 object was stored in the freelist.
1660
Mark Dickinsonb6467572008-08-04 21:30:09 +00001661- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1662 ValueError consistently across platforms.
1663
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001664- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1665 (64bit Unix, for example), unichr() would truncate its argument and return
1666 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1667
Neal Norwitze7d8be82008-07-31 17:17:14 +00001668- Apply security patches from Apple.
1669
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001670- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1671 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1672
Antoine Pitrou92f82162008-07-25 22:22:08 +00001673- Issue #1819: function calls with several named parameters are now on
1674 average 35% faster (as measured by pybench).
1675
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001676- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1677 the python debugger steps into a class statement: the free variables (local
1678 variables defined in an outer scope) would be deleted from the outer scope.
1679
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001680- Issue #2620: Overflow checking when allocating or reallocating memory
1681 was not always being done properly in some python types and extension
1682 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1683 all been updated to perform better checks and places in the code that
1684 would previously leak memory on the error path when such an allocation
1685 failed have been fixed.
1686
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001687Library
1688-------
1689
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001690- Issue #3612: Added some missing basic types in ctypes.wintypes.
1691
Benjamin Petersone977ad42008-08-20 01:42:01 +00001692- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1693 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1694
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001695- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1696 version reported by these tools does not necessarily follow the python
1697 version numbering scheme, so the module is less strict when parsing it.
1698
Nick Coghlanf70385a2008-08-18 12:42:46 +00001699- Issue #2235: Added Py3k warnings for types which will become unhashable
1700 under the stricter __hash__ inheritance rules in 3.0. Several types
1701 which did not meet the rules for hash invariants and were already
1702 unhashable in 3.0 have now been explicitly flagged as unhashable in
1703 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1704 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1705
Brett Cannon88f801d2008-08-18 00:46:22 +00001706- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1707 imported into the module but exposed as part of the module's API.
1708
Brett Cannon7b96f072008-08-18 00:41:11 +00001709- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1710
Brett Cannon46225e72008-08-18 00:36:52 +00001711- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1712
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001713- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1714
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001715- Issue #3575: Incremental decoder's decode function now takes bytearray
1716 by using 's*' instead of 't#'.
1717
Jesus Cea585ad8a2009-07-02 15:37:21 +00001718- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001719 fails unicode conversion on 2nd parameter. (windows only)
1720
Facundo Batista94f243a2008-08-17 03:38:39 +00001721- Issue 2464. urllib2 now supports a malformation in the URL received
1722 in a redirect.
1723
Brett Cannonabe423e2008-08-16 21:47:07 +00001724- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001725 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001726
Facundo Batistaeb90b782008-08-16 14:44:07 +00001727- Issue #2776: fixed small issue when handling an URL with double slash
1728 after a 302 response in the case of not going through a proxy.
1729
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001730- Issue #2676: in the email package, content-type parsing was hanging on
1731 pathological input because of quadratic or exponential behaviour of a
1732 regular expression.
1733
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001734- Issue #3476: binary buffered reading through the new "io" library is now
1735 thread-safe.
1736
Brett Cannonbf3157b2008-08-14 05:00:03 +00001737- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1738 since mimetools itself is deprecated. Because modules are cached, all
1739 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1740
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001741- Issue #3134: shutil referenced undefined WindowsError symbol.
1742
Robert Schuppenies14646332008-08-10 11:01:53 +00001743- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1744 menu entries were not deleted.
1745
Brett Cannon83e81842008-08-09 23:30:55 +00001746- Copied the implementation of reduce() to _functools.reduce() to have a
1747 version that did not raise a DeprecationWarning under -3.
1748
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001749- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1750 a MemoryError rather than silently stop the iteration.
1751
Guido van Rossum59ce9012008-08-09 14:55:34 +00001752- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1753 to _sre.compile() will now be rejected. This should not affect anybody
1754 since the re.compile() function never generates invalid re-bytecode.
1755
Skip Montanaroa032bf42008-08-08 22:52:51 +00001756- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1757 upon first access it can be automatically initialized from the csv file if
1758 it wasn't initialized during instantiation.
1759
Brett Cannon3aa2a492008-08-06 22:28:09 +00001760- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1761 the reload() built-in has been removed.
1762
Brett Cannon7e30b672008-08-04 21:52:25 +00001763- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001764 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1767 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
1768 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1769 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00001770
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001771- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1772 raised an AttributeError.
1773
Benjamin Peterson01a24322008-07-28 23:35:27 +00001774- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001775 asking for a specific length. This problem only affected files opened
1776 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001777
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001778- Issue #3449: Update decimal module to use most recent specification
1779 (v. 1.68) and tests (v. 2.58) from IBM.
1780
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001781- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
1782
Raymond Hettinger8c664e82008-07-25 18:43:33 +00001783- Issue 1592: Improve error reporting when operations are attempted
1784 on a closed shelf.

1787
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001788- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
1789
1790- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1791 invalid arguments.
1792
1793- Issue #3302: Fix several crashes when calling locale's gettext functions
1794 with None arguments.
1795
1796- Issue #3389: Allow resolving dotted names for handlers in logging
1797 configuration files.
1798
1799- Deprecate the sunaudio module for removal in Python 3.0.
1800
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001801- Issue #3394: zipfile.writestr sets external attributes when passed a
1802 file name rather than a ZipInfo instance, so files are extracted with
1803 mode 0600 rather than 000 under Unix.
1804
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001805- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1806 argument in python 2.5, this broke code that subclassed Popen to include its
1807 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1815-------------
1816
Nick Coghlan6e8fef02008-08-18 13:14:22 +00001817- Issue #2235: the C API function PyObject_HashNotImplemented and its
1818 interaction with the tp_hash slot (added in 2.6b2) are now documented
1819
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001820- Issue #643841: The language reference now provides more detailed
1821 coverage of the lookup process for special methods. The disclaimers
1822 regarding lack of coverage of new-style classes have also been
1823 removed, since the coverage is now fairly reasonable.

1827================================
1828
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001829*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001831Core and Builtins
1832-----------------
1833
Georg Brandl3e483f62008-07-16 22:57:41 +00001834- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1835 its methods now allow for items objects that can be converted to
1836 an integer using operator.index().
1837
Mark Dickinson64b7e502008-07-16 09:40:03 +00001838- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1839 produced a ValueError instead of giving the correct float.
1840
Eric Smitha5fa5a22008-07-16 00:11:49 +00001841- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1842 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1843
Mark Dickinson7103aa42008-07-15 19:08:33 +00001844- Issue #3008: the float type has a new instance method 'float.hex'
1845 and a new class method 'float.fromhex' to convert floating-point
1846 numbers to and from hexadecimal strings, respectively.
1847
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001848- Issue #2235: __hash__ is once again inherited by default. To allow
1849 collections.Hashable to remain meaningful in the presence of the
1850 default hash implementation (object.__hash__), it is now possible
1851 to explicit block inheritance of hash by setting __hash__=None at
1852 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1853 level.
1854
Nick Coghlanb028f502008-07-13 14:52:36 +00001855- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1856 the parent module cannot be found while performing an absolute import.
1857 This means that an incorrectly defined __package__ attribute will
1858 now only prevent relative imports in that module rather than causing
1859 all imports from that module to fail.
1860
Nick Coghlan14ff9942008-07-08 14:21:42 +00001861- Issue #2517: Allow unicode messages in Exceptions again by correctly
1862 bypassing the instance dictionary when looking up __unicode__ on
1863 new-style classes.
1864
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001865- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1866 set to a custom object whose write() method happens to install
1867 another file in sys.stdout.
1868
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001869- Issue #3088: Corrected a race condition in classes derived from

1871 another thread's dictionary.
1872
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001873- Issue #3004: Minor change to slice.indices(): the start and stop
1874 arguments are now treated identically, making the behaviour easier
1875 to describe and understand. For example, slice(None, -10,
1876 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1877 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1878 10, -1).
1879
Georg Brandl278fc502008-07-19 12:46:12 +00001880- Issue #3219: Calling a function with repeated keyword arguments,
1881 f(a=2, a=23), would not cause a syntax error. This was a regression

Georg Brandl5cc774e2008-06-11 20:28:06 +00002332 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002333
2334 This is controlled by the configure argument ``--with-universal-archs``:
2335

2337
2338 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2339
2340 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit

2381 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002394- Issue #1631171: Re-implement the 'warnings' module in C (the
2395 original Python code has been kept as backup). This will allow for
2396 using the 'warning's machinery in such places as the parser where
2397 use of pure Python code is not possible. Both the ``showarning()``
2398 and ``formatwarning()`` gain an optional 'line' argument which is
2399 not called by default for backwards-compatibility reasons. Setting
2400 ``warnings.showwarning()`` to an implementation that lacks support
2401 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002464- Issue #2550: The approach used by client/server code for obtaining
2465 ports to listen on in network-oriented tests has been refined in an
2466 effort to facilitate running multiple instances of the entire
2467 regression test suite in parallel without issue.
2468 test_support.bind_port() has been fixed such that it will always
2469 return a unique port -- which wasn't always the case with the
2470 previous implementation, especially if socket options had been set
2471 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2472 new implementation of bind_port() will actually raise an exception
2473 if it is passed an AF_INET/SOCK_STREAM socket with either the
2474 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2475 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2476 the socket it's been passed. This currently only applies to
2477 Windows. This option prevents any other sockets from binding to the
2478 host/port we've bound to, thus removing the possibility of the
2479 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2480 when a second SOCK_STREAM socket binds and accepts to a host/port
2481 that's already been bound by another socket. The optional preferred
2482 port parameter to bind_port() has been removed. Under no
2483 circumstances should tests be hard coding ports!
2484
2485 test_support.find_unused_port() has also been introduced, which will
2486 pass a temporary socket object to bind_port() in order to obtain an
2487 unused port. The temporary socket object is then closed and
2488 deleted, and the port is returned. This method should only be used
2489 for obtaining an unused port in order to pass to an external program
2490 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2491 a parameter to a server-oriented class that doesn't give you direct
2492 access to the underlying socket used.
2493
2494 Finally, test_support.HOST has been introduced, which should be used
2495 for the host argument of any relevant socket calls (i.e. bind and
2496 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002497
2498 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002499 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002500 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2501 test_asynchat and test_socket_ssl.
2502
Georg Brandl3ee81df2008-05-17 18:14:43 +00002503 It is now possible for multiple instances of the regression test
2504 suite to run in parallel without issue.

Fred Drakea8ee94b2008-03-01 02:45:07 +00002773- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002774 644. The mode is now inherited from the py file.

2777
2778- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002779
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002780- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002781 issue 215555 for a discussion.
2782
Eric Smitha73fbe72008-02-23 03:09:44 +00002783- Added the future_builtins module, which contains hex() and oct().
2784 These are the PEP 3127 version of these functions, designed to be
2785 compatible with the hex() and oct() builtins from Python 3.0. They
2786 differ slightly in their output formats from the existing, unchanged
2787 Python 2.6 builtins. The expected usage of the future_builtins
2788 module is:
2789 from future_builtins import hex, oct
2790
Eric Smith7ef40bf2008-02-20 23:34:22 +00002791- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2792 exponents for exponents with absolute value < 100. Follows C99
2793 standard. This is a change on Windows, which would use 3 digits.
2794 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2795 so that any alterations it does to the resulting string will be
2796 available in stringlib/formatter.h (for float.__format__).
2797
Eric Smith5a3c1352008-02-19 13:21:56 +00002798- Implemented PEP 3101, Advanced String Formatting. This adds a new
2799 builtin format(); a format() method for str and unicode; a
2800 __format__() method to object, str, unicode, int, long, float, and
2801 datetime; the class string.Formatter; and the C API
2802 PyObject_Format().
2803
Georg Brandl3ee81df2008-05-17 18:14:43 +00002804- Fixed several potential crashes, all caused by specially crafted
2805 __del__ methods exploiting objects in temporarily inconsistent
2806 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002807
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002808- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002809 prevent a possible crash: an Abstract Base Class would try to access
2810 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002811

Georg Brandl3ee81df2008-05-17 18:14:43 +00002815- Clear all free lists during a gc.collect() of the highest generation
2816 in order to allow pymalloc to free more arenas. Python may give back
2817 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002818
Georg Brandl3ee81df2008-05-17 18:14:43 +00002819- Issue #2045: Fix an infinite recursion triggered when printing a
2820 subclass of collections.defaultdict, if its default_factory is set
2821 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002822
Christian Heimesf75dbef2008-02-08 00:11:31 +00002823- Fixed a minor memory leak in dictobject.c. The content of the free
2824 list was not freed on interpreter shutdown.
2825
Georg Brandl5a7eca12010-03-21 19:29:04 +00002826- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00002827 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002828
Georg Brandl3ee81df2008-05-17 18:14:43 +00002829- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2830 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002831 to compact the internal free lists of pre-allocted ints and floats.
2832
Georg Brandl3ee81df2008-05-17 18:14:43 +00002833- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2834 calls. Python expected the return type int but the fork familie
2835 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002836
Georg Brandl3ee81df2008-05-17 18:14:43 +00002837- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00002849- Patch #1473257: generator objects gain a gi_code attribute. This is
2850 the same object as the func_code attribute of the function that
2851 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002852
Georg Brandl3ee81df2008-05-17 18:14:43 +00002853- Issue #1920: "while 0" statements were completely removed by the
2854 compiler, even in the presence of an "else" clause, which is
2855 supposed to be run when the condition is false. Now the compiler
2856 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002857
Guido van Rossumeead05f2008-01-24 18:21:02 +00002858- A few crashers fixed: weakref_in_del.py (issue #1377858);
2859 loosing_dict_ref.py (issue #1303614, test67.py);
2860 borrowed_ref_[34].py (not in tracker).
2861
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002862- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002863 suppressed while an extension is loaded by calling SetErrorMode in
2864 dynload_win.c. The error is still reported properly.
2865
Georg Brandl3ee81df2008-05-17 18:14:43 +00002866- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002867 several extension methods and modules do not work without unicode
2868 support.
2869
Georg Brandl26543b12008-01-21 18:36:51 +00002870- Issue #1882: when compiling code from a string, encoding cookies in the
2871 second line of code were not always recognized correctly.
2872
Georg Brandl14404b62008-01-19 19:27:05 +00002873- Issue #1679: "0x" was taken as a valid integer literal.
2874
Georg Brandl6caad7d2008-01-26 14:19:22 +00002875- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002876 added.
2877
Christian Heimesc94e2b52008-01-14 04:13:37 +00002878- sys.float_info / PyFloat_GetInfo: The floating point information
2879 object was converted from a dict to a specialized structseq object.
2880
Georg Brandl3ee81df2008-05-17 18:14:43 +00002881- Patch #1816: Added sys.flags structseq. It exposes the status of
2882 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002883
Georg Brandl3ee81df2008-05-17 18:14:43 +00002884- Objects/structseq.c: Implemented new structseq representation. The
2885 patch makes structseqs (e.g. the return value of os.stat) more
2886 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002887
Georg Brandl3ee81df2008-05-17 18:14:43 +00002888- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00002910 and INF. float("nan"), float("inf") and float("-inf") now work on
2911 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002912
Georg Brandl3ee81df2008-05-17 18:14:43 +00002913- Compiler now generates simpler and faster code for dictionary
2914 literals. The oparg for BUILD_MAP now indicates an estimated
2915 dictionary size. There is a new opcode, STORE_MAP, for adding
2916 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002945- Patch #1739468: Directories and zipfiles containing a __main__.py
2946 file can now be directly executed by passing their name to the
2947 interpreter. The directory/zipfile is automatically inserted as the
2948 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002950- Issue #1265: Fix a problem with sys.settrace, if the tracing
2951 function uses a generator expression when at the same time the
2952 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002953
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002954- sets and frozensets now have an isdisjoint() method.
2955

2959
Georg Brandl5a7eca12010-03-21 19:29:04 +00002960- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00002961 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2962 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002963
Georg Brandl3ee81df2008-05-17 18:14:43 +00002964- Issue #1686386: Tuple's tp_repr did not take into account the
2965 possibility of having a self-referential tuple, which is possible
2966 from C code. Nor did object's tp_str consider that a type's tp_str
2967 could do something that could lead to an inifinite recursion.
2968 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2969 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002970
Georg Brandl3ee81df2008-05-17 18:14:43 +00002971- Issue #1164: It was possible to trigger deadlock when using the
2972 'print' statement to write to a file since the GIL was not released
2973 as needed. Now PyObject_Print() does the right thing along with
2974 various tp_print implementations of the built-in types and those in
2975 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002976
Georg Brandl3ee81df2008-05-17 18:14:43 +00002977- Issue #1147: Exceptions were directly allowing string exceptions in
2978 their throw() method even though string exceptions no longer
2979 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002980
Georg Brandl3ee81df2008-05-17 18:14:43 +00002981- Issue #1096: Prevent a segfault from getting the repr of a very
2982 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002983
Brett Cannon1e534b52007-09-07 04:18:30 +00002984- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002985 PyObject_Call() never calling back out to Python code to trigger
2986 recursion depth updates/checks. Required the creation of a static
2987 RuntimeError instance in case normalizing an exception put the
2988 recursion check value past its limit. Fixes crashers
2989 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002990

Neal Norwitz0ac60192007-05-27 04:08:54 +00003004- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003005 __*__ attributes. (Some already existed, e.g., __doc__ and
3006 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003007
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003008- Add -3 option to the interpreter to warn about features that are
3009 deprecated and will be changed/removed in Python 3.0.
3010
Georg Brandl2134e752007-05-21 20:34:16 +00003011- Patch #1686487: you can now pass any mapping after '**' in function
3012 calls.
3013
Collin Winter62903052007-05-18 23:11:24 +00003014- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003015 "except E as target:". This is to provide forwards compatibility
3016 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003017
Brett Cannon229cee22007-05-05 01:34:02 +00003018- Deprecate BaseException.message as per PEP 352.
3019
Georg Brandl3ee81df2008-05-17 18:14:43 +00003020- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003021 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003022
Vinay Sajip8549ce32007-05-06 17:53:37 +00003023- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003024 setting a plain string, ie don't expand to single letter identifiers.
3025
Raymond Hettinger13936692007-04-11 18:40:58 +00003026- Request #1191699: Slices can now be pickled.
3027
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003028- Request #1193128: str.translate() now allows a None argument for
3029 translations that only remove characters without re-mapping the
3030 remaining characters.
3031
Georg Brandl5cb76c12007-03-21 09:00:39 +00003032- Patch #1682205: a TypeError while unpacking an iterable is no longer
3033 masked by a generic one with the message "unpack non-sequence".
3034
Neal Norwitzaa754b72007-03-21 06:39:48 +00003035- Remove unused file Python/fmod.c.
3036
Guido van Rossum143b5642007-03-23 04:58:42 +00003037- Bug #1683368: The object.__init__() and object.__new__() methods are
3038 now stricter in rejecting excess arguments. The only time when
3039 either allows excess arguments is when it is not overridden and the
3040 other one is. For backwards compatibility, when both are
3041 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003042 warning later). Also, type.__init__() insists on the same signature
3043 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003044
Georg Brandl3ee81df2008-05-17 18:14:43 +00003045- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3046 object to complex using its __complex__() method before falling back
3047 to the __float__() method. Therefore, the functions in the cmath
3048 module now can operate on objects that define a __complex__()
3049 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003050
Georg Brandl3ee81df2008-05-17 18:14:43 +00003051- Patch #1623563: allow __class__ assignment for classes with
3052 __slots__. The old and the new class are still required to have the
3053 same slot names.

3059 ``object.__reduce_ex__()`` is called with an object that is faking
3060 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003061
Georg Brandl3ee81df2008-05-17 18:14:43 +00003062- Patch #1680015: Don't modify __slots__ tuple if it contains an

3066
Georg Brandl7b9c5552007-03-12 14:30:05 +00003067- Bug #1678647: write a newline after printing an exception in any
3068 case, even when converting the value to a string failed.
3069
Georg Brandl871f1bc2007-03-12 13:17:36 +00003070- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003071 its argument, if it exists. If not, it will work like before. This
3072 allows customizing the output of dir() in the presence of a
3073 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003081- Patch #1491866: change the complex() constructor to allow
3082 parthensized forms. This means complex(repr(x)) now works instead of
3083 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003084
Georg Brandlaa2321b2007-03-07 00:40:28 +00003085- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003086 makes the filenames the warning module prints much more sensible
3087 when a PYTHONSTARTUP file is used.

Georg Brandl098cd692007-03-06 12:17:50 +00003099
Georg Brandl0fca97a2007-03-05 22:28:08 +00003100- Patch #1674228: when assigning a slice (old-style), check for the
3101 sq_ass_slice instead of the sq_slice slot.
3102
Georg Brandl3ee81df2008-05-17 18:14:43 +00003103- When printing an unraisable error, don't print exceptions. before
3104 the name. This duplicates the behavior whening normally printing
3105 exceptions.

3734 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004015- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4016 with RFC 3207 and forgets any knowledge obtained from the server not
4017 obtained from the TLS negotiation itself. Patch contributed by Bill
4018 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004019
Georg Brandl3ee81df2008-05-17 18:14:43 +00004020- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004021 that the SMTP.starttls() caller no longer needs to call ehlo()
4022 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004023 does not claim to support starttls. Adds the
4024 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4025 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004079- itertools.chain() now has an alternate constructor,

4105 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4106 silently miscode subclasses of those types. Now, it raises a
4107 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004108

Georg Brandl3ee81df2008-05-17 18:14:43 +00004123 time so that opening a database previously created with the DB_DUP
4124 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4125 opens. Specifically: dictionary assignment to a DB object will
4126 replace all values for a given key when the database allows
4127 duplicate values. DB users should use DB.put(k, v) when they want
4128 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004129

4135 characters with ASCII value less than 32. Also, it correctly quotes
4136 dots only if they occur on a single line, as opposed to the previous
4137 behavior of quoting dots if they are the second character of any
4138 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004139

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004407- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00004408 periodic threadstate and signal checking in tight loops. By
4409 default, this option is turned-off. It should only be enabled in
4410 debugged, performance critical applications.

4461-----
4462
Georg Brandl3ee81df2008-05-17 18:14:43 +00004463- Unified naming convention for free lists and their limits. All free
4464 lists in Object/ are named ``free_list``, the counter ``numfree``
4465 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4466 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004467
Georg Brandl3ee81df2008-05-17 18:14:43 +00004468- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4469 to ``PyTuple_SetItem``, it can be used to populate a brand new
4470 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004471

4482
Georg Brandl3ee81df2008-05-17 18:14:43 +00004483- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4484 of w# format code incorrectly truncated the length to an int, even
4485 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4486 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004487
Georg Brandl3ee81df2008-05-17 18:14:43 +00004488- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4508
4509- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4510 outside of pystate.c and should not be necessary.
4511
Georg Brandl3ee81df2008-05-17 18:14:43 +00004512- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4513 absolute imports. In earlier versions they might have used relative
4514 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004515
Georg Brandl3ee81df2008-05-17 18:14:43 +00004516- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4517 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004518
Georg Brandl3ee81df2008-05-17 18:14:43 +00004519- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

4527 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4528 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4529 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004530

Georg Brandl3ee81df2008-05-17 18:14:43 +00004544- Removed the macfs module. It had been deprecated since Python 2.5.
4545 This lead to the deprecation of macostools.touched() as it relied
4546 solely on macfs and was a no-op under OS X.
