1278What's New in Python 2.6.1
1279==========================
1280
1281*Release date: 04-Dec-2008*
1282
1283Core and Builtins
1284-----------------
1285
1286- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1287 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1288 instead of throwing a MemoryError.
1289
1290- Issue #4367: Python would segfault during compiling when the unicodedata
1291 module couldn't be imported and \N escapes were present.
1292
1293- Issue #4348: Some bytearray methods returned that didn't cause any change to
1294 the bytearray, returned the same bytearray instead of a copy.
1295
1296- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1297
1298- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1299
1300- Issue #4048: The parser module now correctly validates relative imports.
1301
1302- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1303 exec statement.
1304
1305- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1306 method does not return iterators for the 4th and 5th items.
1307
1308- Issue #4209: Enabling unicode_literals and the print_function in the same
1309 __future__ import didn't work.
1310
1311- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1312 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1313 really executed because I cannot move to such directory on win2k)
1314
1315- Issue #4069: When set.remove(element) is used with a set element, the element
1316 is temporarily replaced with an equivalent frozenset. But the eventual
1317 KeyError would always report the empty frozenset([]) as the missing key. Now
1318 it correctly refers to the initial element.
1319
1320- Fixed C99 style comments in several files. Python is now C89 compatible
1321 again.

1469
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001470- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1471 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1472 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1473 ``printf`` function, whereas PyString_FromFormat has an independent
1474 implementation and uses "%zd" on all platforms for size_t values.
1475 This makes a difference on win64, where ``printf`` needs "%Id" to display
1476 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001478- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Antoine Pitrou0668c622008-08-26 22:42:08 +00001496 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1497 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1498 when given a tuple of classes as second argument, were looking up
1499 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1500 type object.

Benjamin Peterson37346b22008-08-23 20:27:43 +00001592Extension Modules
1593-----------------
1594
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001595- Issue #2975: When compiling several extension modules with Visual Studio 2008
1596 from the same python interpreter, some environment variables would grow
1597 without limit.
1598
Benjamin Peterson37346b22008-08-23 20:27:43 +00001599- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
1600 exploitation of poor argument checking.
1601
Gerhard Häringef2276b2008-09-12 13:54:06 +00001602- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
1603

1605 remaining ones have "pysqlite_" prefix.
1606
Gerhard Häringe6872eb2008-09-12 22:33:22 +00001607- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

1613
Nick Coghland2e09382008-09-11 12:11:06 +00001614- Issue #3781: Add test.test_support.check_warnings() as a convenience
1615 wrapper for warnings.catch_warnings() that makes it easier to check
1616 that expected warning messages are being reported.
1617
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00001618- Issue #3796: Some tests functions were not enabled in test_float.
1619

Martin v. Löwisab0b29b2008-09-13 08:11:57 +00001625- Issue #3833: Use a different upgrade code for Win64 installers.
1626
Martin v. Löwis3f5fda82008-09-08 13:50:10 +00001627- Issue #2271: Set SecureCustomProperties so that installation will properly
1628 use the TARGETDIR even for unprivileged users.
1629
Martin v. Löwis67543a92008-09-08 12:02:45 +00001630- Allow passing the MSI file name to merge.py.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001636What's New in Python 2.6 beta 3?
1637================================
1638
Barry Warsaw07a4a382008-08-21 01:15:08 +00001639*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001640
1641Core and Builtins
1642-----------------
1643
Guido van Rossumf8402962008-08-20 15:01:50 +00001644- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1645 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1646 extensions do not automatically benefit from the class attribute
1647 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1648 to their tp_flags field if they care. This is a backwards
1649 compatibility feature; in 3.0, all types will use the cache by
1650 default.
1651
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001652- Keyword arguments can now follow starred arguments. (``f(a, *args,
1653 keyword=23)`` is now valid syntax.)
1654
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001655- ctypes function pointers that are COM methods have a boolean True
1656 value again.
1657
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001658- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1659 by denying s# to parse objects that have a releasebuffer procedure,
1660 and introducing s*.
1661
Georg Brandl1e13ea92008-08-11 09:07:59 +00001662- Issue #3537: Fix an assertion failure when an empty but presized dict
1663 object was stored in the freelist.
1664
Mark Dickinsonb6467572008-08-04 21:30:09 +00001665- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1666 ValueError consistently across platforms.
1667
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001668- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1669 (64bit Unix, for example), unichr() would truncate its argument and return
1670 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1671
Neal Norwitze7d8be82008-07-31 17:17:14 +00001672- Apply security patches from Apple.
1673
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001674- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1675 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1676
Antoine Pitrou92f82162008-07-25 22:22:08 +00001677- Issue #1819: function calls with several named parameters are now on
1678 average 35% faster (as measured by pybench).
1679
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001680- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1681 the python debugger steps into a class statement: the free variables (local
1682 variables defined in an outer scope) would be deleted from the outer scope.
1683
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001684- Issue #2620: Overflow checking when allocating or reallocating memory
1685 was not always being done properly in some python types and extension
1686 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1687 all been updated to perform better checks and places in the code that
1688 would previously leak memory on the error path when such an allocation
1689 failed have been fixed.
1690
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001691Library
1692-------
1693
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001694- Issue #3612: Added some missing basic types in ctypes.wintypes.
1695
Benjamin Petersone977ad42008-08-20 01:42:01 +00001696- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1697 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1698
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001699- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1700 version reported by these tools does not necessarily follow the python
1701 version numbering scheme, so the module is less strict when parsing it.
1702
Nick Coghlanf70385a2008-08-18 12:42:46 +00001703- Issue #2235: Added Py3k warnings for types which will become unhashable
1704 under the stricter __hash__ inheritance rules in 3.0. Several types
1705 which did not meet the rules for hash invariants and were already
1706 unhashable in 3.0 have now been explicitly flagged as unhashable in
1707 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1708 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1709
Brett Cannon88f801d2008-08-18 00:46:22 +00001710- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1711 imported into the module but exposed as part of the module's API.
1712
Brett Cannon7b96f072008-08-18 00:41:11 +00001713- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1714
Brett Cannon46225e72008-08-18 00:36:52 +00001715- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1716
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001717- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1718
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001719- Issue #3575: Incremental decoder's decode function now takes bytearray
1720 by using 's*' instead of 't#'.
1721
Jesus Cea585ad8a2009-07-02 15:37:21 +00001722- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001723 fails unicode conversion on 2nd parameter. (windows only)
1724
Facundo Batista94f243a2008-08-17 03:38:39 +00001725- Issue 2464. urllib2 now supports a malformation in the URL received
1726 in a redirect.
1727
Brett Cannonabe423e2008-08-16 21:47:07 +00001728- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001729 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001730
Facundo Batistaeb90b782008-08-16 14:44:07 +00001731- Issue #2776: fixed small issue when handling an URL with double slash
1732 after a 302 response in the case of not going through a proxy.
1733
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001734- Issue #2676: in the email package, content-type parsing was hanging on
1735 pathological input because of quadratic or exponential behaviour of a
1736 regular expression.
1737
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001738- Issue #3476: binary buffered reading through the new "io" library is now
1739 thread-safe.
1740
Brett Cannonbf3157b2008-08-14 05:00:03 +00001741- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1742 since mimetools itself is deprecated. Because modules are cached, all
1743 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1744
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001745- Issue #3134: shutil referenced undefined WindowsError symbol.
1746
Robert Schuppenies14646332008-08-10 11:01:53 +00001747- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1748 menu entries were not deleted.
1749
Brett Cannon83e81842008-08-09 23:30:55 +00001750- Copied the implementation of reduce() to _functools.reduce() to have a
1751 version that did not raise a DeprecationWarning under -3.
1752
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001753- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1754 a MemoryError rather than silently stop the iteration.
1755
Guido van Rossum59ce9012008-08-09 14:55:34 +00001756- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1757 to _sre.compile() will now be rejected. This should not affect anybody
1758 since the re.compile() function never generates invalid re-bytecode.
1759
Skip Montanaroa032bf42008-08-08 22:52:51 +00001760- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1761 upon first access it can be automatically initialized from the csv file if
1762 it wasn't initialized during instantiation.
1763
Brett Cannon3aa2a492008-08-06 22:28:09 +00001764- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1765 the reload() built-in has been removed.
1766
Brett Cannon7e30b672008-08-04 21:52:25 +00001767- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001768 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1772 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1773 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.

Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001775- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1776 raised an AttributeError.
1777
Benjamin Peterson01a24322008-07-28 23:35:27 +00001778- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001779 asking for a specific length. This problem only affected files opened
1780 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001781
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001782- Issue #3449: Update decimal module to use most recent specification
1783 (v. 1.68) and tests (v. 2.58) from IBM.
1784

1793
1794- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1795 invalid arguments.
1796
1797- Issue #3302: Fix several crashes when calling locale's gettext functions
1798 with None arguments.

1800- Issue #3389: Allow resolving dotted names for handlers in logging
1801 configuration files.
1802
1803- Deprecate the sunaudio module for removal in Python 3.0.
1804
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001805- Issue #3394: zipfile.writestr sets external attributes when passed a
1806 file name rather than a ZipInfo instance, so files are extracted with
1807 mode 0600 rather than 000 under Unix.
1808
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001809- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1810 argument in python 2.5, this broke code that subclassed Popen to include its
1811 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1819-------------
1820
Nick Coghlan6e8fef02008-08-18 13:14:22 +00001821- Issue #2235: the C API function PyObject_HashNotImplemented and its
1822 interaction with the tp_hash slot (added in 2.6b2) are now documented
1823
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001824- Issue #643841: The language reference now provides more detailed
1825 coverage of the lookup process for special methods. The disclaimers
1826 regarding lack of coverage of new-style classes have also been
1827 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001830What's New in Python 2.6 beta 2?
1831================================
1832
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001833*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001835Core and Builtins
1836-----------------
1837
Georg Brandl3e483f62008-07-16 22:57:41 +00001838- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1839 its methods now allow for items objects that can be converted to
1840 an integer using operator.index().
1841
Mark Dickinson64b7e502008-07-16 09:40:03 +00001842- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1843 produced a ValueError instead of giving the correct float.
1844
Eric Smitha5fa5a22008-07-16 00:11:49 +00001845- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1846 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1847
Mark Dickinson7103aa42008-07-15 19:08:33 +00001848- Issue #3008: the float type has a new instance method 'float.hex'
1849 and a new class method 'float.fromhex' to convert floating-point
1850 numbers to and from hexadecimal strings, respectively.
1851
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001852- Issue #2235: __hash__ is once again inherited by default. To allow
1853 collections.Hashable to remain meaningful in the presence of the
1854 default hash implementation (object.__hash__), it is now possible
1855 to explicit block inheritance of hash by setting __hash__=None at
1856 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1857 level.
1858
Nick Coghlanb028f502008-07-13 14:52:36 +00001859- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1860 the parent module cannot be found while performing an absolute import.
1861 This means that an incorrectly defined __package__ attribute will
1862 now only prevent relative imports in that module rather than causing
1863 all imports from that module to fail.
1864
Nick Coghlan14ff9942008-07-08 14:21:42 +00001865- Issue #2517: Allow unicode messages in Exceptions again by correctly
1866 bypassing the instance dictionary when looking up __unicode__ on
1867 new-style classes.
1868
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001869- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1870 set to a custom object whose write() method happens to install
1871 another file in sys.stdout.
1872
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001873- Issue #3088: Corrected a race condition in classes derived from

1875 another thread's dictionary.
1876
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001877- Issue #3004: Minor change to slice.indices(): the start and stop
1878 arguments are now treated identically, making the behaviour easier
1879 to describe and understand. For example, slice(None, -10,
1880 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1881 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1882 10, -1).

Georg Brandl5cc774e2008-06-11 20:28:06 +00002336 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002337
2338 This is controlled by the configure argument ``--with-universal-archs``:

2341
2342 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2343
2344 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2345
2346 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002398- Issue #1631171: Re-implement the 'warnings' module in C (the
2399 original Python code has been kept as backup). This will allow for
2400 using the 'warning's machinery in such places as the parser where
2401 use of pure Python code is not possible. Both the ``showarning()``
2402 and ``formatwarning()`` gain an optional 'line' argument which is
2403 not called by default for backwards-compatibility reasons. Setting
2404 ``warnings.showwarning()`` to an implementation that lacks support
2405 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithaa63d0d2008-04-06 23:11:17 +00002451- Issue #815646: Individual file objects may now be used from multiple
2452 threads at once without fear of crashing the Python interpreter. If
2453 file.close() is called while an object is in use by another thread
2454 an IOError exception will be raised and the file will not be closed.
2455
Thomas Hellerf7906482008-04-04 19:43:25 +00002456- The bundled libffi copy is now in sync with the recently released

Georg Brandl3ee81df2008-05-17 18:14:43 +00002468- Issue #2550: The approach used by client/server code for obtaining
2469 ports to listen on in network-oriented tests has been refined in an
2470 effort to facilitate running multiple instances of the entire
2471 regression test suite in parallel without issue.
2472 test_support.bind_port() has been fixed such that it will always
2473 return a unique port -- which wasn't always the case with the
2474 previous implementation, especially if socket options had been set
2475 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2476 new implementation of bind_port() will actually raise an exception
2477 if it is passed an AF_INET/SOCK_STREAM socket with either the
2478 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2479 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2480 the socket it's been passed. This currently only applies to
2481 Windows. This option prevents any other sockets from binding to the
2482 host/port we've bound to, thus removing the possibility of the
2483 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2484 when a second SOCK_STREAM socket binds and accepts to a host/port
2485 that's already been bound by another socket. The optional preferred
2486 port parameter to bind_port() has been removed. Under no
2487 circumstances should tests be hard coding ports!
2488
2489 test_support.find_unused_port() has also been introduced, which will
2490 pass a temporary socket object to bind_port() in order to obtain an
2491 unused port. The temporary socket object is then closed and
2492 deleted, and the port is returned. This method should only be used
2493 for obtaining an unused port in order to pass to an external program
2494 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2495 a parameter to a server-oriented class that doesn't give you direct
2496 access to the underlying socket used.
2497
2498 Finally, test_support.HOST has been introduced, which should be used
2499 for the host argument of any relevant socket calls (i.e. bind and
2500 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002501
2502 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002503 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002504 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2505 test_asynchat and test_socket_ssl.
2506
Georg Brandl3ee81df2008-05-17 18:14:43 +00002507 It is now possible for multiple instances of the regression test
2508 suite to run in parallel without issue.

Fred Drakea8ee94b2008-03-01 02:45:07 +00002777- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002778 644. The mode is now inherited from the py file.

2781
2782- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002783
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002784- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002785 issue 215555 for a discussion.
2786
Eric Smitha73fbe72008-02-23 03:09:44 +00002787- Added the future_builtins module, which contains hex() and oct().
2788 These are the PEP 3127 version of these functions, designed to be
2789 compatible with the hex() and oct() builtins from Python 3.0. They
2790 differ slightly in their output formats from the existing, unchanged
2791 Python 2.6 builtins. The expected usage of the future_builtins
2792 module is:
2793 from future_builtins import hex, oct
2794
Eric Smith7ef40bf2008-02-20 23:34:22 +00002795- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2796 exponents for exponents with absolute value < 100. Follows C99
2797 standard. This is a change on Windows, which would use 3 digits.
2798 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2799 so that any alterations it does to the resulting string will be
2800 available in stringlib/formatter.h (for float.__format__).
2801
Eric Smith5a3c1352008-02-19 13:21:56 +00002802- Implemented PEP 3101, Advanced String Formatting. This adds a new
2803 builtin format(); a format() method for str and unicode; a
2804 __format__() method to object, str, unicode, int, long, float, and
2805 datetime; the class string.Formatter; and the C API
2806 PyObject_Format().
2807
Georg Brandl3ee81df2008-05-17 18:14:43 +00002808- Fixed several potential crashes, all caused by specially crafted
2809 __del__ methods exploiting objects in temporarily inconsistent
2810 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002811
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002812- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002813 prevent a possible crash: an Abstract Base Class would try to access
2814 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002819- Clear all free lists during a gc.collect() of the highest generation
2820 in order to allow pymalloc to free more arenas. Python may give back
2821 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002822
Georg Brandl3ee81df2008-05-17 18:14:43 +00002823- Issue #2045: Fix an infinite recursion triggered when printing a
2824 subclass of collections.defaultdict, if its default_factory is set
2825 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002826
Christian Heimesf75dbef2008-02-08 00:11:31 +00002827- Fixed a minor memory leak in dictobject.c. The content of the free
2828 list was not freed on interpreter shutdown.
2829
Georg Brandl5a7eca12010-03-21 19:29:04 +00002830- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00002831 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002832
Georg Brandl3ee81df2008-05-17 18:14:43 +00002833- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2834 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002835 to compact the internal free lists of pre-allocted ints and floats.
2836
Georg Brandl3ee81df2008-05-17 18:14:43 +00002837- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2838 calls. Python expected the return type int but the fork familie
2839 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002840
Georg Brandl3ee81df2008-05-17 18:14:43 +00002841- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2842 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002843
Georg Brandl3ee81df2008-05-17 18:14:43 +00002844- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2845 with the collections.Sequence API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002850- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2851 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002852
Georg Brandl3ee81df2008-05-17 18:14:43 +00002853- Patch #1473257: generator objects gain a gi_code attribute. This is
2854 the same object as the func_code attribute of the function that
2855 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002856
Georg Brandl3ee81df2008-05-17 18:14:43 +00002857- Issue #1920: "while 0" statements were completely removed by the
2858 compiler, even in the presence of an "else" clause, which is
2859 supposed to be run when the condition is false. Now the compiler
2860 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002861
Guido van Rossumeead05f2008-01-24 18:21:02 +00002862- A few crashers fixed: weakref_in_del.py (issue #1377858);
2863 loosing_dict_ref.py (issue #1303614, test67.py);
2864 borrowed_ref_[34].py (not in tracker).
2865
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002866- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002867 suppressed while an extension is loaded by calling SetErrorMode in
2868 dynload_win.c. The error is still reported properly.
2869
Georg Brandl3ee81df2008-05-17 18:14:43 +00002870- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002871 several extension methods and modules do not work without unicode
2872 support.
2873
Georg Brandl26543b12008-01-21 18:36:51 +00002874- Issue #1882: when compiling code from a string, encoding cookies in the
2875 second line of code were not always recognized correctly.
2876
Georg Brandl14404b62008-01-19 19:27:05 +00002877- Issue #1679: "0x" was taken as a valid integer literal.
2878
Georg Brandl6caad7d2008-01-26 14:19:22 +00002879- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002880 added.
2881
Christian Heimesc94e2b52008-01-14 04:13:37 +00002882- sys.float_info / PyFloat_GetInfo: The floating point information
2883 object was converted from a dict to a specialized structseq object.
2884
Georg Brandl3ee81df2008-05-17 18:14:43 +00002885- Patch #1816: Added sys.flags structseq. It exposes the status of
2886 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002887
Georg Brandl3ee81df2008-05-17 18:14:43 +00002888- Objects/structseq.c: Implemented new structseq representation. The
2889 patch makes structseqs (e.g. the return value of os.stat) more
2890 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002891
Georg Brandl3ee81df2008-05-17 18:14:43 +00002892- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00002904- Improve some exception messages when Windows fails to load an
2905 extension module. Now we get for example '%1 is not a valid Win32
2906 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002914 and INF. float("nan"), float("inf") and float("-inf") now work on
2915 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002916
Georg Brandl3ee81df2008-05-17 18:14:43 +00002917- Compiler now generates simpler and faster code for dictionary
2918 literals. The oparg for BUILD_MAP now indicates an estimated
2919 dictionary size. There is a new opcode, STORE_MAP, for adding
2920 entries to the dictionary.

2945
Georg Brandl3ee81df2008-05-17 18:14:43 +00002946- Issue #1460: The utf-7 incremental decoder did not accept truncated
2947 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00002948
Georg Brandl3ee81df2008-05-17 18:14:43 +00002949- Patch #1739468: Directories and zipfiles containing a __main__.py
2950 file can now be directly executed by passing their name to the
2951 interpreter. The directory/zipfile is automatically inserted as the
2952 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002953
Georg Brandl3ee81df2008-05-17 18:14:43 +00002954- Issue #1265: Fix a problem with sys.settrace, if the tracing
2955 function uses a generator expression when at the same time the
2956 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002957
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002958- sets and frozensets now have an isdisjoint() method.
2959

2961
Neal Norwitz44f326e2007-10-05 05:29:17 +00002962- Fix warnings found by the new version of the Coverity checker.
2963
Georg Brandl5a7eca12010-03-21 19:29:04 +00002964- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00002965 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2966 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002967
Georg Brandl3ee81df2008-05-17 18:14:43 +00002968- Issue #1686386: Tuple's tp_repr did not take into account the
2969 possibility of having a self-referential tuple, which is possible
2970 from C code. Nor did object's tp_str consider that a type's tp_str
2971 could do something that could lead to an inifinite recursion.
2972 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2973 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002974
Georg Brandl3ee81df2008-05-17 18:14:43 +00002975- Issue #1164: It was possible to trigger deadlock when using the
2976 'print' statement to write to a file since the GIL was not released
2977 as needed. Now PyObject_Print() does the right thing along with
2978 various tp_print implementations of the built-in types and those in
2979 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002980
Georg Brandl3ee81df2008-05-17 18:14:43 +00002981- Issue #1147: Exceptions were directly allowing string exceptions in
2982 their throw() method even though string exceptions no longer
2983 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002984
Georg Brandl3ee81df2008-05-17 18:14:43 +00002985- Issue #1096: Prevent a segfault from getting the repr of a very
2986 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002987
Brett Cannon1e534b52007-09-07 04:18:30 +00002988- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002989 PyObject_Call() never calling back out to Python code to trigger
2990 recursion depth updates/checks. Required the creation of a static
2991 RuntimeError instance in case normalizing an exception put the
2992 recursion check value past its limit. Fixes crashers
2993 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002994
Georg Brandl3ee81df2008-05-17 18:14:43 +00002995- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003008- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003009 __*__ attributes. (Some already existed, e.g., __doc__ and
3010 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003011
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003012- Add -3 option to the interpreter to warn about features that are
3013 deprecated and will be changed/removed in Python 3.0.
3014
Georg Brandl2134e752007-05-21 20:34:16 +00003015- Patch #1686487: you can now pass any mapping after '**' in function
3016 calls.
3017
Collin Winter62903052007-05-18 23:11:24 +00003018- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003019 "except E as target:". This is to provide forwards compatibility
3020 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003021
Brett Cannon229cee22007-05-05 01:34:02 +00003022- Deprecate BaseException.message as per PEP 352.
3023
Georg Brandl3ee81df2008-05-17 18:14:43 +00003024- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003025 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003026
Vinay Sajip8549ce32007-05-06 17:53:37 +00003027- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003028 setting a plain string, ie don't expand to single letter identifiers.
3029
Raymond Hettinger13936692007-04-11 18:40:58 +00003030- Request #1191699: Slices can now be pickled.
3031
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003032- Request #1193128: str.translate() now allows a None argument for
3033 translations that only remove characters without re-mapping the
3034 remaining characters.
3035
Georg Brandl5cb76c12007-03-21 09:00:39 +00003036- Patch #1682205: a TypeError while unpacking an iterable is no longer
3037 masked by a generic one with the message "unpack non-sequence".
3038
Neal Norwitzaa754b72007-03-21 06:39:48 +00003039- Remove unused file Python/fmod.c.
3040
Guido van Rossum143b5642007-03-23 04:58:42 +00003041- Bug #1683368: The object.__init__() and object.__new__() methods are
3042 now stricter in rejecting excess arguments. The only time when
3043 either allows excess arguments is when it is not overridden and the
3044 other one is. For backwards compatibility, when both are
3045 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003046 warning later). Also, type.__init__() insists on the same signature
3047 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003048
Georg Brandl3ee81df2008-05-17 18:14:43 +00003049- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3050 object to complex using its __complex__() method before falling back
3051 to the __float__() method. Therefore, the functions in the cmath
3052 module now can operate on objects that define a __complex__()
3053 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003054
Georg Brandl3ee81df2008-05-17 18:14:43 +00003055- Patch #1623563: allow __class__ assignment for classes with
3056 __slots__. The old and the new class are still required to have the
3057 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003058
Georg Brandl3ee81df2008-05-17 18:14:43 +00003059- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00003062- Patch #1462488: Python no longer segfaults when
3063 ``object.__reduce_ex__()`` is called with an object that is faking
3064 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003065
Georg Brandl3ee81df2008-05-17 18:14:43 +00003066- Patch #1680015: Don't modify __slots__ tuple if it contains an

3070
Georg Brandl7b9c5552007-03-12 14:30:05 +00003071- Bug #1678647: write a newline after printing an exception in any
3072 case, even when converting the value to a string failed.
3073
Georg Brandl871f1bc2007-03-12 13:17:36 +00003074- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003075 its argument, if it exists. If not, it will work like before. This
3076 allows customizing the output of dir() in the presence of a
3077 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003078
Collin Winter276887b2007-03-12 16:11:39 +00003079- Patch #922167: Python no longer segfaults when faced with infinitely
3080 self-recursive reload() calls (as reported by bug #742342).
3081
Georg Brandl3ee81df2008-05-17 18:14:43 +00003082- Patch #1675981: remove unreachable code from ``type.__new__()``
3083 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003085- Patch #1491866: change the complex() constructor to allow
3086 parthensized forms. This means complex(repr(x)) now works instead of
3087 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003088
Georg Brandlaa2321b2007-03-07 00:40:28 +00003089- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003090 makes the filenames the warning module prints much more sensible
3091 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003092
Georg Brandl49aafc92007-03-07 00:34:46 +00003093- Variant of patch #697613: don't exit the interpreter on a SystemExit
3094 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003095 variable is given, but break into the interactive interpreter just
3096 like on other exceptions or normal program exit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003101- Bug #1674503: close the file opened by execfile() in an error
3102 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00003103
Georg Brandl0fca97a2007-03-05 22:28:08 +00003104- Patch #1674228: when assigning a slice (old-style), check for the
3105 sq_ass_slice instead of the sq_slice slot.
3106
Georg Brandl3ee81df2008-05-17 18:14:43 +00003107- When printing an unraisable error, don't print exceptions. before
3108 the name. This duplicates the behavior whening normally printing
3109 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00003110
Georg Brandl3ee81df2008-05-17 18:14:43 +00003111- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00003117- Bug #1377858: Fix the segfaulting of the interpreter when an object
3118 created a weakref on itself during a __del__ call for new-style
3119 classes (classic classes still have the bug).

3166
Armin Rigo7ccbca92006-10-04 12:17:45 +00003167- A number of places, including integer negation and absolute value,

3675
Georg Brandl92a6bae2007-03-13 17:43:32 +00003676- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003677 are set for invalid interpolation sequences that would lead to

3734 TestCase and TestSuite subclasses (not instances) are no longer
3735 accepted in TestSuite.addTest(). This should cause no
3736 incompatibility since it never made sense with ordinary subclasses
3737 -- the failure just occurred later, with a more cumbersome
3738 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004019- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4020 with RFC 3207 and forgets any knowledge obtained from the server not
4021 obtained from the TLS negotiation itself. Patch contributed by Bill
4022 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004023
Georg Brandl3ee81df2008-05-17 18:14:43 +00004024- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004025 that the SMTP.starttls() caller no longer needs to call ehlo()
4026 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004027 does not claim to support starttls. Adds the
4028 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00004083- itertools.chain() now has an alternate constructor,

4109 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4110 silently miscode subclasses of those types. Now, it raises a
4111 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004112

Georg Brandl3ee81df2008-05-17 18:14:43 +00004127 time so that opening a database previously created with the DB_DUP
4128 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4129 opens. Specifically: dictionary assignment to a DB object will
4130 replace all values for a given key when the database allows
4131 duplicate values. DB users should use DB.put(k, v) when they want
4132 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004133

4139 characters with ASCII value less than 32. Also, it correctly quotes
4140 dots only if they occur on a single line, as opposed to the previous
4141 behavior of quoting dots if they are the second character of any
4142 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004143

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004411- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00004412 periodic threadstate and signal checking in tight loops. By
4413 default, this option is turned-off. It should only be enabled in
4414 debugged, performance critical applications.

Christian Heimes5b970ad2008-02-06 13:33:44 +00004471
Georg Brandl3ee81df2008-05-17 18:14:43 +00004472- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4473 to ``PyTuple_SetItem``, it can be used to populate a brand new

4486
Georg Brandl3ee81df2008-05-17 18:14:43 +00004487- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4488 of w# format code incorrectly truncated the length to an int, even
4489 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4490 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004491
Georg Brandl3ee81df2008-05-17 18:14:43 +00004492- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4514 outside of pystate.c and should not be necessary.
4515
Georg Brandl3ee81df2008-05-17 18:14:43 +00004516- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4517 absolute imports. In earlier versions they might have used relative
4518 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004519
Georg Brandl3ee81df2008-05-17 18:14:43 +00004520- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4521 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004522
Georg Brandl3ee81df2008-05-17 18:14:43 +00004523- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004548- Removed the macfs module. It had been deprecated since Python 2.5.
4549 This lead to the deprecation of macostools.touched() as it relied
4550 solely on macfs and was a no-op under OS X.
