1283What's New in Python 2.6.1
1284==========================
1285
1286*Release date: 04-Dec-2008*
1287
1288Core and Builtins
1289-----------------
1290
1291- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1292 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1293 instead of throwing a MemoryError.
1294
1295- Issue #4367: Python would segfault during compiling when the unicodedata
1296 module couldn't be imported and \N escapes were present.
1297
1298- Issue #4348: Some bytearray methods returned that didn't cause any change to
1299 the bytearray, returned the same bytearray instead of a copy.
1300
1301- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1302
1303- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1304
1305- Issue #4048: The parser module now correctly validates relative imports.
1306
1307- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1308 exec statement.
1309
1310- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1311 method does not return iterators for the 4th and 5th items.
1312
1313- Issue #4209: Enabling unicode_literals and the print_function in the same
1314 __future__ import didn't work.
1315
1316- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1317 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1318 really executed because I cannot move to such directory on win2k)
1319
1320- Issue #4069: When set.remove(element) is used with a set element, the element
1321 is temporarily replaced with an equivalent frozenset. But the eventual
1322 KeyError would always report the empty frozenset([]) as the missing key. Now
1323 it correctly refers to the initial element.
1324
1325- Fixed C99 style comments in several files. Python is now C89 compatible
1326 again.

1474
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001475- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1476 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1477 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1478 ``printf`` function, whereas PyString_FromFormat has an independent
1479 implementation and uses "%zd" on all platforms for size_t values.
1480 This makes a difference on win64, where ``printf`` needs "%Id" to display
1481 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001483- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Antoine Pitrou0668c622008-08-26 22:42:08 +00001501 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1502 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1503 when given a tuple of classes as second argument, were looking up
1504 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1505 type object.

1598-----------------
1599
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001600- Issue #2975: When compiling several extension modules with Visual Studio 2008
1601 from the same python interpreter, some environment variables would grow
1602 without limit.
1603
Benjamin Peterson37346b22008-08-23 20:27:43 +00001604- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
1605 exploitation of poor argument checking.
1606
Gerhard Häringef2276b2008-09-12 13:54:06 +00001607- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

1610 remaining ones have "pysqlite_" prefix.
1611
Gerhard Häringe6872eb2008-09-12 22:33:22 +00001612- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

Nick Coghland2e09382008-09-11 12:11:06 +00001619- Issue #3781: Add test.test_support.check_warnings() as a convenience
1620 wrapper for warnings.catch_warnings() that makes it easier to check
1621 that expected warning messages are being reported.
1622
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00001623- Issue #3796: Some tests functions were not enabled in test_float.
1624

1631
Martin v. Löwis3f5fda82008-09-08 13:50:10 +00001632- Issue #2271: Set SecureCustomProperties so that installation will properly

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001641What's New in Python 2.6 beta 3?
1642================================
1643
Barry Warsaw07a4a382008-08-21 01:15:08 +00001644*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001645
1646Core and Builtins
1647-----------------
1648
Guido van Rossumf8402962008-08-20 15:01:50 +00001649- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1650 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1651 extensions do not automatically benefit from the class attribute
1652 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1653 to their tp_flags field if they care. This is a backwards
1654 compatibility feature; in 3.0, all types will use the cache by
1655 default.
1656
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001657- Keyword arguments can now follow starred arguments. (``f(a, *args,
1658 keyword=23)`` is now valid syntax.)
1659
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001660- ctypes function pointers that are COM methods have a boolean True
1661 value again.
1662
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001663- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1664 by denying s# to parse objects that have a releasebuffer procedure,
1665 and introducing s*.
1666
Georg Brandl1e13ea92008-08-11 09:07:59 +00001667- Issue #3537: Fix an assertion failure when an empty but presized dict
1668 object was stored in the freelist.
1669
Mark Dickinsonb6467572008-08-04 21:30:09 +00001670- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1671 ValueError consistently across platforms.
1672
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001673- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1674 (64bit Unix, for example), unichr() would truncate its argument and return
1675 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1676
Neal Norwitze7d8be82008-07-31 17:17:14 +00001677- Apply security patches from Apple.
1678
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001679- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1680 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1681
Antoine Pitrou92f82162008-07-25 22:22:08 +00001682- Issue #1819: function calls with several named parameters are now on
1683 average 35% faster (as measured by pybench).
1684
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001685- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1686 the python debugger steps into a class statement: the free variables (local
1687 variables defined in an outer scope) would be deleted from the outer scope.
1688
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001689- Issue #2620: Overflow checking when allocating or reallocating memory
1690 was not always being done properly in some python types and extension
1691 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1692 all been updated to perform better checks and places in the code that
1693 would previously leak memory on the error path when such an allocation
1694 failed have been fixed.
1695
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001696Library
1697-------
1698
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001699- Issue #3612: Added some missing basic types in ctypes.wintypes.
1700
Benjamin Petersone977ad42008-08-20 01:42:01 +00001701- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1702 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1703
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001704- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1705 version reported by these tools does not necessarily follow the python
1706 version numbering scheme, so the module is less strict when parsing it.
1707
Nick Coghlanf70385a2008-08-18 12:42:46 +00001708- Issue #2235: Added Py3k warnings for types which will become unhashable
1709 under the stricter __hash__ inheritance rules in 3.0. Several types
1710 which did not meet the rules for hash invariants and were already
1711 unhashable in 3.0 have now been explicitly flagged as unhashable in
1712 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1713 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1714
Brett Cannon88f801d2008-08-18 00:46:22 +00001715- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1716 imported into the module but exposed as part of the module's API.
1717
Brett Cannon7b96f072008-08-18 00:41:11 +00001718- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1719
Brett Cannon46225e72008-08-18 00:36:52 +00001720- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001722- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1723
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001724- Issue #3575: Incremental decoder's decode function now takes bytearray
1725 by using 's*' instead of 't#'.
1726
Jesus Cea585ad8a2009-07-02 15:37:21 +00001727- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001728 fails unicode conversion on 2nd parameter. (windows only)
1729
Facundo Batista94f243a2008-08-17 03:38:39 +00001730- Issue 2464. urllib2 now supports a malformation in the URL received
1731 in a redirect.
1732
Brett Cannonabe423e2008-08-16 21:47:07 +00001733- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001734 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001735
Facundo Batistaeb90b782008-08-16 14:44:07 +00001736- Issue #2776: fixed small issue when handling an URL with double slash
1737 after a 302 response in the case of not going through a proxy.
1738
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001739- Issue #2676: in the email package, content-type parsing was hanging on
1740 pathological input because of quadratic or exponential behaviour of a
1741 regular expression.
1742
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001743- Issue #3476: binary buffered reading through the new "io" library is now
1744 thread-safe.
1745
Brett Cannonbf3157b2008-08-14 05:00:03 +00001746- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1747 since mimetools itself is deprecated. Because modules are cached, all
1748 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1749
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001750- Issue #3134: shutil referenced undefined WindowsError symbol.
1751
Robert Schuppenies14646332008-08-10 11:01:53 +00001752- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1753 menu entries were not deleted.
1754
Brett Cannon83e81842008-08-09 23:30:55 +00001755- Copied the implementation of reduce() to _functools.reduce() to have a
1756 version that did not raise a DeprecationWarning under -3.
1757
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001758- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1759 a MemoryError rather than silently stop the iteration.
1760
Guido van Rossum59ce9012008-08-09 14:55:34 +00001761- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1762 to _sre.compile() will now be rejected. This should not affect anybody
1763 since the re.compile() function never generates invalid re-bytecode.
1764
Skip Montanaroa032bf42008-08-08 22:52:51 +00001765- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1766 upon first access it can be automatically initialized from the csv file if
1767 it wasn't initialized during instantiation.
1768
Brett Cannon3aa2a492008-08-06 22:28:09 +00001769- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1770 the reload() built-in has been removed.
1771
Brett Cannon7e30b672008-08-04 21:52:25 +00001772- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001773 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001780- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1781 raised an AttributeError.
1782
Benjamin Peterson01a24322008-07-28 23:35:27 +00001783- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001784 asking for a specific length. This problem only affected files opened
1785 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001786
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001787- Issue #3449: Update decimal module to use most recent specification
1788 (v. 1.68) and tests (v. 2.58) from IBM.
1789

1798
1799- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1800 invalid arguments.
1801
1802- Issue #3302: Fix several crashes when calling locale's gettext functions
1803 with None arguments.

1805- Issue #3389: Allow resolving dotted names for handlers in logging
1806 configuration files.
1807
1808- Deprecate the sunaudio module for removal in Python 3.0.
1809
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001810- Issue #3394: zipfile.writestr sets external attributes when passed a
1811 file name rather than a ZipInfo instance, so files are extracted with
1812 mode 0600 rather than 000 under Unix.
1813
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001814- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1815 argument in python 2.5, this broke code that subclassed Popen to include its
1816 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1825
Nick Coghlan6e8fef02008-08-18 13:14:22 +00001826- Issue #2235: the C API function PyObject_HashNotImplemented and its
1827 interaction with the tp_hash slot (added in 2.6b2) are now documented
1828
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001829- Issue #643841: The language reference now provides more detailed
1830 coverage of the lookup process for special methods. The disclaimers
1831 regarding lack of coverage of new-style classes have also been
1832 removed, since the coverage is now fairly reasonable.

1837
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001838*Release date: 17-Jul-2008*

1841-----------------
1842
Georg Brandl3e483f62008-07-16 22:57:41 +00001843- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1844 its methods now allow for items objects that can be converted to
1845 an integer using operator.index().
1846
Mark Dickinson64b7e502008-07-16 09:40:03 +00001847- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1848 produced a ValueError instead of giving the correct float.
1849
Eric Smitha5fa5a22008-07-16 00:11:49 +00001850- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1851 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1852
Mark Dickinson7103aa42008-07-15 19:08:33 +00001853- Issue #3008: the float type has a new instance method 'float.hex'
1854 and a new class method 'float.fromhex' to convert floating-point
1855 numbers to and from hexadecimal strings, respectively.
1856
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001857- Issue #2235: __hash__ is once again inherited by default. To allow
1858 collections.Hashable to remain meaningful in the presence of the
1859 default hash implementation (object.__hash__), it is now possible
1860 to explicit block inheritance of hash by setting __hash__=None at
1861 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1862 level.
1863
Nick Coghlanb028f502008-07-13 14:52:36 +00001864- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1865 the parent module cannot be found while performing an absolute import.
1866 This means that an incorrectly defined __package__ attribute will
1867 now only prevent relative imports in that module rather than causing
1868 all imports from that module to fail.
1869
Nick Coghlan14ff9942008-07-08 14:21:42 +00001870- Issue #2517: Allow unicode messages in Exceptions again by correctly
1871 bypassing the instance dictionary when looking up __unicode__ on
1872 new-style classes.
1873
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001874- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1875 set to a custom object whose write() method happens to install
1876 another file in sys.stdout.

1880 another thread's dictionary.
1881
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001882- Issue #3004: Minor change to slice.indices(): the start and stop
1883 arguments are now treated identically, making the behaviour easier
1884 to describe and understand. For example, slice(None, -10,
1885 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1886 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1887 10, -1).

Georg Brandl5cc774e2008-06-11 20:28:06 +00002341 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002342
2343 This is controlled by the configure argument ``--with-universal-archs``:
2344

2346
2347 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2348
2349 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit

2390 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002403- Issue #1631171: Re-implement the 'warnings' module in C (the
2404 original Python code has been kept as backup). This will allow for
2405 using the 'warning's machinery in such places as the parser where
2406 use of pure Python code is not possible. Both the ``showarning()``
2407 and ``formatwarning()`` gain an optional 'line' argument which is
2408 not called by default for backwards-compatibility reasons. Setting
2409 ``warnings.showwarning()`` to an implementation that lacks support
2410 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002473- Issue #2550: The approach used by client/server code for obtaining
2474 ports to listen on in network-oriented tests has been refined in an
2475 effort to facilitate running multiple instances of the entire
2476 regression test suite in parallel without issue.
2477 test_support.bind_port() has been fixed such that it will always
2478 return a unique port -- which wasn't always the case with the
2479 previous implementation, especially if socket options had been set
2480 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2481 new implementation of bind_port() will actually raise an exception
2482 if it is passed an AF_INET/SOCK_STREAM socket with either the
2483 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2484 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2485 the socket it's been passed. This currently only applies to
2486 Windows. This option prevents any other sockets from binding to the
2487 host/port we've bound to, thus removing the possibility of the
2488 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2489 when a second SOCK_STREAM socket binds and accepts to a host/port
2490 that's already been bound by another socket. The optional preferred
2491 port parameter to bind_port() has been removed. Under no
2492 circumstances should tests be hard coding ports!
2493
2494 test_support.find_unused_port() has also been introduced, which will
2495 pass a temporary socket object to bind_port() in order to obtain an
2496 unused port. The temporary socket object is then closed and
2497 deleted, and the port is returned. This method should only be used
2498 for obtaining an unused port in order to pass to an external program
2499 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2500 a parameter to a server-oriented class that doesn't give you direct
2501 access to the underlying socket used.
2502
2503 Finally, test_support.HOST has been introduced, which should be used
2504 for the host argument of any relevant socket calls (i.e. bind and
2505 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002506
2507 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002508 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002509 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2510 test_asynchat and test_socket_ssl.
2511
Georg Brandl3ee81df2008-05-17 18:14:43 +00002512 It is now possible for multiple instances of the regression test
2513 suite to run in parallel without issue.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00002789- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002790 issue 215555 for a discussion.
2791
Eric Smitha73fbe72008-02-23 03:09:44 +00002792- Added the future_builtins module, which contains hex() and oct().
2793 These are the PEP 3127 version of these functions, designed to be
2794 compatible with the hex() and oct() builtins from Python 3.0. They
2795 differ slightly in their output formats from the existing, unchanged
2796 Python 2.6 builtins. The expected usage of the future_builtins
2797 module is:
2798 from future_builtins import hex, oct
2799
Eric Smith7ef40bf2008-02-20 23:34:22 +00002800- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2801 exponents for exponents with absolute value < 100. Follows C99
2802 standard. This is a change on Windows, which would use 3 digits.
2803 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2804 so that any alterations it does to the resulting string will be
2805 available in stringlib/formatter.h (for float.__format__).
2806
Eric Smith5a3c1352008-02-19 13:21:56 +00002807- Implemented PEP 3101, Advanced String Formatting. This adds a new
2808 builtin format(); a format() method for str and unicode; a
2809 __format__() method to object, str, unicode, int, long, float, and
2810 datetime; the class string.Formatter; and the C API
2811 PyObject_Format().
2812
Georg Brandl3ee81df2008-05-17 18:14:43 +00002813- Fixed several potential crashes, all caused by specially crafted
2814 __del__ methods exploiting objects in temporarily inconsistent
2815 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002816
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002817- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002818 prevent a possible crash: an Abstract Base Class would try to access
2819 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002824- Clear all free lists during a gc.collect() of the highest generation
2825 in order to allow pymalloc to free more arenas. Python may give back
2826 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002827
Georg Brandl3ee81df2008-05-17 18:14:43 +00002828- Issue #2045: Fix an infinite recursion triggered when printing a
2829 subclass of collections.defaultdict, if its default_factory is set
2830 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002831
Christian Heimesf75dbef2008-02-08 00:11:31 +00002832- Fixed a minor memory leak in dictobject.c. The content of the free
2833 list was not freed on interpreter shutdown.
2834
Georg Brandl5a7eca12010-03-21 19:29:04 +00002835- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00002836 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002837
Georg Brandl3ee81df2008-05-17 18:14:43 +00002838- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2839 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002840 to compact the internal free lists of pre-allocted ints and floats.
2841
Georg Brandl3ee81df2008-05-17 18:14:43 +00002842- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2843 calls. Python expected the return type int but the fork familie
2844 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002845
Georg Brandl3ee81df2008-05-17 18:14:43 +00002846- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2847 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002848
Georg Brandl3ee81df2008-05-17 18:14:43 +00002849- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2850 with the collections.Sequence API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002855- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2856 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002857
Georg Brandl3ee81df2008-05-17 18:14:43 +00002858- Patch #1473257: generator objects gain a gi_code attribute. This is
2859 the same object as the func_code attribute of the function that
2860 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002861
Georg Brandl3ee81df2008-05-17 18:14:43 +00002862- Issue #1920: "while 0" statements were completely removed by the
2863 compiler, even in the presence of an "else" clause, which is
2864 supposed to be run when the condition is false. Now the compiler
2865 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002866
Guido van Rossumeead05f2008-01-24 18:21:02 +00002867- A few crashers fixed: weakref_in_del.py (issue #1377858);
2868 loosing_dict_ref.py (issue #1303614, test67.py);
2869 borrowed_ref_[34].py (not in tracker).
2870
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002871- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002872 suppressed while an extension is loaded by calling SetErrorMode in
2873 dynload_win.c. The error is still reported properly.
2874
Georg Brandl3ee81df2008-05-17 18:14:43 +00002875- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002876 several extension methods and modules do not work without unicode
2877 support.
2878
Georg Brandl26543b12008-01-21 18:36:51 +00002879- Issue #1882: when compiling code from a string, encoding cookies in the
2880 second line of code were not always recognized correctly.
2881
Georg Brandl14404b62008-01-19 19:27:05 +00002882- Issue #1679: "0x" was taken as a valid integer literal.
2883
Georg Brandl6caad7d2008-01-26 14:19:22 +00002884- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002885 added.
2886
Christian Heimesc94e2b52008-01-14 04:13:37 +00002887- sys.float_info / PyFloat_GetInfo: The floating point information
2888 object was converted from a dict to a specialized structseq object.
2889
Georg Brandl3ee81df2008-05-17 18:14:43 +00002890- Patch #1816: Added sys.flags structseq. It exposes the status of
2891 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002892
Georg Brandl3ee81df2008-05-17 18:14:43 +00002893- Objects/structseq.c: Implemented new structseq representation. The
2894 patch makes structseqs (e.g. the return value of os.stat) more
2895 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002896
Georg Brandl3ee81df2008-05-17 18:14:43 +00002897- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00002909- Improve some exception messages when Windows fails to load an
2910 extension module. Now we get for example '%1 is not a valid Win32
2911 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002919 and INF. float("nan"), float("inf") and float("-inf") now work on
2920 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002921
Georg Brandl3ee81df2008-05-17 18:14:43 +00002922- Compiler now generates simpler and faster code for dictionary
2923 literals. The oparg for BUILD_MAP now indicates an estimated
2924 dictionary size. There is a new opcode, STORE_MAP, for adding
2925 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002954- Patch #1739468: Directories and zipfiles containing a __main__.py
2955 file can now be directly executed by passing their name to the
2956 interpreter. The directory/zipfile is automatically inserted as the
2957 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002958
Georg Brandl3ee81df2008-05-17 18:14:43 +00002959- Issue #1265: Fix a problem with sys.settrace, if the tracing
2960 function uses a generator expression when at the same time the
2961 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002962
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002963- sets and frozensets now have an isdisjoint() method.
2964

2966
Neal Norwitz44f326e2007-10-05 05:29:17 +00002967- Fix warnings found by the new version of the Coverity checker.
2968
Georg Brandl5a7eca12010-03-21 19:29:04 +00002969- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00002970 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2971 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002972
Georg Brandl3ee81df2008-05-17 18:14:43 +00002973- Issue #1686386: Tuple's tp_repr did not take into account the
2974 possibility of having a self-referential tuple, which is possible
2975 from C code. Nor did object's tp_str consider that a type's tp_str
2976 could do something that could lead to an inifinite recursion.
2977 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2978 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002979
Georg Brandl3ee81df2008-05-17 18:14:43 +00002980- Issue #1164: It was possible to trigger deadlock when using the
2981 'print' statement to write to a file since the GIL was not released
2982 as needed. Now PyObject_Print() does the right thing along with
2983 various tp_print implementations of the built-in types and those in
2984 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002985
Georg Brandl3ee81df2008-05-17 18:14:43 +00002986- Issue #1147: Exceptions were directly allowing string exceptions in
2987 their throw() method even though string exceptions no longer
2988 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002989
Georg Brandl3ee81df2008-05-17 18:14:43 +00002990- Issue #1096: Prevent a segfault from getting the repr of a very
2991 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002992
Brett Cannon1e534b52007-09-07 04:18:30 +00002993- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002994 PyObject_Call() never calling back out to Python code to trigger
2995 recursion depth updates/checks. Required the creation of a static
2996 RuntimeError instance in case normalizing an exception put the
2997 recursion check value past its limit. Fixes crashers
2998 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002999
Georg Brandl3ee81df2008-05-17 18:14:43 +00003000- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003013- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003014 __*__ attributes. (Some already existed, e.g., __doc__ and
3015 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003016
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003017- Add -3 option to the interpreter to warn about features that are
3018 deprecated and will be changed/removed in Python 3.0.
3019
Georg Brandl2134e752007-05-21 20:34:16 +00003020- Patch #1686487: you can now pass any mapping after '**' in function
3021 calls.
3022
Collin Winter62903052007-05-18 23:11:24 +00003023- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003024 "except E as target:". This is to provide forwards compatibility
3025 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003026
Brett Cannon229cee22007-05-05 01:34:02 +00003027- Deprecate BaseException.message as per PEP 352.
3028
Georg Brandl3ee81df2008-05-17 18:14:43 +00003029- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003030 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003031
Vinay Sajip8549ce32007-05-06 17:53:37 +00003032- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003033 setting a plain string, ie don't expand to single letter identifiers.
3034
Raymond Hettinger13936692007-04-11 18:40:58 +00003035- Request #1191699: Slices can now be pickled.
3036
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003037- Request #1193128: str.translate() now allows a None argument for
3038 translations that only remove characters without re-mapping the
3039 remaining characters.
3040
Georg Brandl5cb76c12007-03-21 09:00:39 +00003041- Patch #1682205: a TypeError while unpacking an iterable is no longer
3042 masked by a generic one with the message "unpack non-sequence".
3043
Neal Norwitzaa754b72007-03-21 06:39:48 +00003044- Remove unused file Python/fmod.c.
3045
Guido van Rossum143b5642007-03-23 04:58:42 +00003046- Bug #1683368: The object.__init__() and object.__new__() methods are
3047 now stricter in rejecting excess arguments. The only time when
3048 either allows excess arguments is when it is not overridden and the
3049 other one is. For backwards compatibility, when both are
3050 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003051 warning later). Also, type.__init__() insists on the same signature
3052 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003053
Georg Brandl3ee81df2008-05-17 18:14:43 +00003054- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3055 object to complex using its __complex__() method before falling back
3056 to the __float__() method. Therefore, the functions in the cmath
3057 module now can operate on objects that define a __complex__()
3058 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003059
Georg Brandl3ee81df2008-05-17 18:14:43 +00003060- Patch #1623563: allow __class__ assignment for classes with
3061 __slots__. The old and the new class are still required to have the
3062 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003063
Georg Brandl3ee81df2008-05-17 18:14:43 +00003064- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00003067- Patch #1462488: Python no longer segfaults when
3068 ``object.__reduce_ex__()`` is called with an object that is faking
3069 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003070
Georg Brandl3ee81df2008-05-17 18:14:43 +00003071- Patch #1680015: Don't modify __slots__ tuple if it contains an

3075
Georg Brandl7b9c5552007-03-12 14:30:05 +00003076- Bug #1678647: write a newline after printing an exception in any
3077 case, even when converting the value to a string failed.
3078
Georg Brandl871f1bc2007-03-12 13:17:36 +00003079- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003080 its argument, if it exists. If not, it will work like before. This
3081 allows customizing the output of dir() in the presence of a
3082 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003083
Collin Winter276887b2007-03-12 16:11:39 +00003084- Patch #922167: Python no longer segfaults when faced with infinitely
3085 self-recursive reload() calls (as reported by bug #742342).
3086
Georg Brandl3ee81df2008-05-17 18:14:43 +00003087- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00003090- Patch #1491866: change the complex() constructor to allow
3091 parthensized forms. This means complex(repr(x)) now works instead of
3092 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003093
Georg Brandlaa2321b2007-03-07 00:40:28 +00003094- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003095 makes the filenames the warning module prints much more sensible
3096 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003097
Georg Brandl49aafc92007-03-07 00:34:46 +00003098- Variant of patch #697613: don't exit the interpreter on a SystemExit
3099 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003100 variable is given, but break into the interactive interpreter just
3101 like on other exceptions or normal program exit.

3107 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00003108
Georg Brandl0fca97a2007-03-05 22:28:08 +00003109- Patch #1674228: when assigning a slice (old-style), check for the
3110 sq_ass_slice instead of the sq_slice slot.
3111
Georg Brandl3ee81df2008-05-17 18:14:43 +00003112- When printing an unraisable error, don't print exceptions. before
3113 the name. This duplicates the behavior whening normally printing
3114 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00003115
Georg Brandl3ee81df2008-05-17 18:14:43 +00003116- Bug #1653736: Properly discard third argument to

3123 created a weakref on itself during a __del__ call for new-style
3124 classes (classic classes still have the bug).

3171
Armin Rigo7ccbca92006-10-04 12:17:45 +00003172- A number of places, including integer negation and absolute value,

3680
Georg Brandl92a6bae2007-03-13 17:43:32 +00003681- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003682 are set for invalid interpolation sequences that would lead to

3739 TestCase and TestSuite subclasses (not instances) are no longer
3740 accepted in TestSuite.addTest(). This should cause no
3741 incompatibility since it never made sense with ordinary subclasses
3742 -- the failure just occurred later, with a more cumbersome
3743 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004024- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4025 with RFC 3207 and forgets any knowledge obtained from the server not
4026 obtained from the TLS negotiation itself. Patch contributed by Bill
4027 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004028
Georg Brandl3ee81df2008-05-17 18:14:43 +00004029- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004030 that the SMTP.starttls() caller no longer needs to call ehlo()
4031 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004032 does not claim to support starttls. Adds the
4033 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00004088- itertools.chain() now has an alternate constructor,

4114 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4115 silently miscode subclasses of those types. Now, it raises a
4116 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004117

Georg Brandl3ee81df2008-05-17 18:14:43 +00004132 time so that opening a database previously created with the DB_DUP
4133 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4134 opens. Specifically: dictionary assignment to a DB object will
4135 replace all values for a given key when the database allows
4136 duplicate values. DB users should use DB.put(k, v) when they want
4137 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004138

4144 characters with ASCII value less than 32. Also, it correctly quotes
4145 dots only if they occur on a single line, as opposed to the previous
4146 behavior of quoting dots if they are the second character of any
4147 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004148

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004416- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00004417 periodic threadstate and signal checking in tight loops. By
4418 default, this option is turned-off. It should only be enabled in
4419 debugged, performance critical applications.

Christian Heimes5b970ad2008-02-06 13:33:44 +00004476
Georg Brandl3ee81df2008-05-17 18:14:43 +00004477- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4478 to ``PyTuple_SetItem``, it can be used to populate a brand new

4491
Georg Brandl3ee81df2008-05-17 18:14:43 +00004492- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4493 of w# format code incorrectly truncated the length to an int, even
4494 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4495 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004496
Georg Brandl3ee81df2008-05-17 18:14:43 +00004497- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

Georg Brandl3ee81df2008-05-17 18:14:43 +00004525- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4526 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004527
Georg Brandl3ee81df2008-05-17 18:14:43 +00004528- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004553- Removed the macfs module. It had been deprecated since Python 2.5.
4554 This lead to the deprecation of macostools.touched() as it relied
4555 solely on macfs and was a no-op under OS X.
