1298What's New in Python 2.6.1
1299==========================
1300
1301*Release date: 04-Dec-2008*
1302
1303Core and Builtins
1304-----------------
1305
1306- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1307 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1308 instead of throwing a MemoryError.
1309
1310- Issue #4367: Python would segfault during compiling when the unicodedata
1311 module couldn't be imported and \N escapes were present.
1312
1313- Issue #4348: Some bytearray methods returned that didn't cause any change to
1314 the bytearray, returned the same bytearray instead of a copy.
1315
1316- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1317
1318- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1319
1320- Issue #4048: The parser module now correctly validates relative imports.
1321
1322- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1323 exec statement.
1324
1325- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1326 method does not return iterators for the 4th and 5th items.
1327
1328- Issue #4209: Enabling unicode_literals and the print_function in the same
1329 __future__ import didn't work.
1330
1331- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1332 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1333 really executed because I cannot move to such directory on win2k)
1334
1335- Issue #4069: When set.remove(element) is used with a set element, the element
1336 is temporarily replaced with an equivalent frozenset. But the eventual
1337 KeyError would always report the empty frozenset([]) as the missing key. Now
1338 it correctly refers to the initial element.
1339
1340- Fixed C99 style comments in several files. Python is now C89 compatible
1341 again.

1489
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001490- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1491 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1492 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1493 ``printf`` function, whereas PyString_FromFormat has an independent
1494 implementation and uses "%zd" on all platforms for size_t values.
1495 This makes a difference on win64, where ``printf`` needs "%Id" to display
1496 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001498- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Vinay Sajip35e3b032008-09-01 14:33:59 +00001515- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001516 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1517 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1518 when given a tuple of classes as second argument, were looking up
1519 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1520 type object.

1592 for catch_warnings() also led to an improvement in the raising of a
1593 DeprecationWarning related to warnings.warn_explicit().
1594
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001595- The deprecation warnings for the old camelCase threading API were removed.
1596
Vinay Sajip35e3b032008-09-01 14:33:59 +00001597- logging: fixed lack of use of encoding attribute specified on a stream.
1598
Christian Heimesa27a62e2008-08-22 19:55:54 +00001599- Silenced a trivial compiler warning in the sqlite module.
1600
Christian Heimes1cc69632008-08-22 20:10:27 +00001601- Fixed two format strings in the _collections module.
1602
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001603- Issue #3703: _fileio.FileIO gave unhelpful error message when trying to open a
1604 directory.
Benjamin Petersonf22c26e2008-09-01 14:13:43 +00001605
Gregory P. Smithd7122032008-09-02 05:36:11 +00001606- Issue #3708: os.urandom no longer goes into an infinite loop when passed a
1607 non-integer floating point number.
1608
Vinay Sajip65d66e12008-09-04 07:31:21 +00001609- Issue #3110: multiprocessing fails to compiel on solaris 10 due to missing

Benjamin Peterson37346b22008-08-23 20:27:43 +00001612Extension Modules
1613-----------------
1614
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001615- Issue #2975: When compiling several extension modules with Visual Studio 2008
1616 from the same python interpreter, some environment variables would grow
1617 without limit.
1618
Benjamin Peterson37346b22008-08-23 20:27:43 +00001619- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
1620 exploitation of poor argument checking.
1621
Gerhard Häringef2276b2008-09-12 13:54:06 +00001622- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
1623
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00001624- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
1625 remaining ones have "pysqlite_" prefix.
1626
Gerhard Häringe6872eb2008-09-12 22:33:22 +00001627- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves
1628 concurrent access to the same SQLite database from multiple
1629 threads/processes.

Nick Coghland2e09382008-09-11 12:11:06 +00001634- Issue #3781: Add test.test_support.check_warnings() as a convenience
1635 wrapper for warnings.catch_warnings() that makes it easier to check
1636 that expected warning messages are being reported.
1637
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00001638- Issue #3796: Some tests functions were not enabled in test_float.

1646
Martin v. Löwis3f5fda82008-09-08 13:50:10 +00001647- Issue #2271: Set SecureCustomProperties so that installation will properly

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001656What's New in Python 2.6 beta 3?
1657================================
1658
Barry Warsaw07a4a382008-08-21 01:15:08 +00001659*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001660
1661Core and Builtins
1662-----------------
1663
Guido van Rossumf8402962008-08-20 15:01:50 +00001664- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1665 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1666 extensions do not automatically benefit from the class attribute
1667 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1668 to their tp_flags field if they care. This is a backwards
1669 compatibility feature; in 3.0, all types will use the cache by
1670 default.
1671
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001672- Keyword arguments can now follow starred arguments. (``f(a, *args,
1673 keyword=23)`` is now valid syntax.)
1674
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001675- ctypes function pointers that are COM methods have a boolean True
1676 value again.
1677
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001678- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1679 by denying s# to parse objects that have a releasebuffer procedure,
1680 and introducing s*.
1681
Georg Brandl1e13ea92008-08-11 09:07:59 +00001682- Issue #3537: Fix an assertion failure when an empty but presized dict
1683 object was stored in the freelist.
1684
Mark Dickinsonb6467572008-08-04 21:30:09 +00001685- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1686 ValueError consistently across platforms.
1687
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001688- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1689 (64bit Unix, for example), unichr() would truncate its argument and return
1690 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1691
Neal Norwitze7d8be82008-07-31 17:17:14 +00001692- Apply security patches from Apple.
1693
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001694- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1695 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1696
Antoine Pitrou92f82162008-07-25 22:22:08 +00001697- Issue #1819: function calls with several named parameters are now on
1698 average 35% faster (as measured by pybench).
1699
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001700- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1701 the python debugger steps into a class statement: the free variables (local
1702 variables defined in an outer scope) would be deleted from the outer scope.
1703
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001704- Issue #2620: Overflow checking when allocating or reallocating memory
1705 was not always being done properly in some python types and extension
1706 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1707 all been updated to perform better checks and places in the code that
1708 would previously leak memory on the error path when such an allocation
1709 failed have been fixed.
1710
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001711Library
1712-------
1713
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001714- Issue #3612: Added some missing basic types in ctypes.wintypes.
1715
Benjamin Petersone977ad42008-08-20 01:42:01 +00001716- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1717 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1718
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001719- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1720 version reported by these tools does not necessarily follow the python
1721 version numbering scheme, so the module is less strict when parsing it.
1722
Nick Coghlanf70385a2008-08-18 12:42:46 +00001723- Issue #2235: Added Py3k warnings for types which will become unhashable
1724 under the stricter __hash__ inheritance rules in 3.0. Several types
1725 which did not meet the rules for hash invariants and were already
1726 unhashable in 3.0 have now been explicitly flagged as unhashable in
1727 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1728 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1729
Brett Cannon88f801d2008-08-18 00:46:22 +00001730- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1731 imported into the module but exposed as part of the module's API.
1732
Brett Cannon7b96f072008-08-18 00:41:11 +00001733- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1734
Brett Cannon46225e72008-08-18 00:36:52 +00001735- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001737- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1738
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001739- Issue #3575: Incremental decoder's decode function now takes bytearray
1740 by using 's*' instead of 't#'.
1741
Jesus Cea585ad8a2009-07-02 15:37:21 +00001742- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001743 fails unicode conversion on 2nd parameter. (windows only)
1744
Facundo Batista94f243a2008-08-17 03:38:39 +00001745- Issue 2464. urllib2 now supports a malformation in the URL received
1746 in a redirect.
1747
Brett Cannonabe423e2008-08-16 21:47:07 +00001748- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001749 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001750
Facundo Batistaeb90b782008-08-16 14:44:07 +00001751- Issue #2776: fixed small issue when handling an URL with double slash
1752 after a 302 response in the case of not going through a proxy.
1753
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001754- Issue #2676: in the email package, content-type parsing was hanging on
1755 pathological input because of quadratic or exponential behaviour of a
1756 regular expression.
1757
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001758- Issue #3476: binary buffered reading through the new "io" library is now
1759 thread-safe.
1760
Brett Cannonbf3157b2008-08-14 05:00:03 +00001761- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1762 since mimetools itself is deprecated. Because modules are cached, all
1763 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1764
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001765- Issue #3134: shutil referenced undefined WindowsError symbol.
1766
Robert Schuppenies14646332008-08-10 11:01:53 +00001767- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1768 menu entries were not deleted.
1769
Brett Cannon83e81842008-08-09 23:30:55 +00001770- Copied the implementation of reduce() to _functools.reduce() to have a
1771 version that did not raise a DeprecationWarning under -3.
1772
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001773- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1774 a MemoryError rather than silently stop the iteration.
1775
Guido van Rossum59ce9012008-08-09 14:55:34 +00001776- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1777 to _sre.compile() will now be rejected. This should not affect anybody
1778 since the re.compile() function never generates invalid re-bytecode.
1779
Skip Montanaroa032bf42008-08-08 22:52:51 +00001780- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1781 upon first access it can be automatically initialized from the csv file if
1782 it wasn't initialized during instantiation.
1783
Brett Cannon3aa2a492008-08-06 22:28:09 +00001784- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1785 the reload() built-in has been removed.
1786
Brett Cannon7e30b672008-08-04 21:52:25 +00001787- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001788 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1796 raised an AttributeError.
1797
Benjamin Peterson01a24322008-07-28 23:35:27 +00001798- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001799 asking for a specific length. This problem only affected files opened
1800 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001801
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001802- Issue #3449: Update decimal module to use most recent specification
1803 (v. 1.68) and tests (v. 2.58) from IBM.

1824
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001825- Issue #3394: zipfile.writestr sets external attributes when passed a
1826 file name rather than a ZipInfo instance, so files are extracted with
1827 mode 0600 rather than 000 under Unix.
1828
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001829- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1830 argument in python 2.5, this broke code that subclassed Popen to include its
1831 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001841- Issue #2235: the C API function PyObject_HashNotImplemented and its
1842 interaction with the tp_hash slot (added in 2.6b2) are now documented
1843
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001844- Issue #643841: The language reference now provides more detailed
1845 coverage of the lookup process for special methods. The disclaimers
1846 regarding lack of coverage of new-style classes have also been
1847 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001850What's New in Python 2.6 beta 2?
1851================================
1852
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001853*Release date: 17-Jul-2008*

1856-----------------
1857
Georg Brandl3e483f62008-07-16 22:57:41 +00001858- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1859 its methods now allow for items objects that can be converted to
1860 an integer using operator.index().
1861
Mark Dickinson64b7e502008-07-16 09:40:03 +00001862- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1863 produced a ValueError instead of giving the correct float.
1864
Eric Smitha5fa5a22008-07-16 00:11:49 +00001865- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1866 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1867
Mark Dickinson7103aa42008-07-15 19:08:33 +00001868- Issue #3008: the float type has a new instance method 'float.hex'
1869 and a new class method 'float.fromhex' to convert floating-point
1870 numbers to and from hexadecimal strings, respectively.
1871
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001872- Issue #2235: __hash__ is once again inherited by default. To allow
1873 collections.Hashable to remain meaningful in the presence of the
1874 default hash implementation (object.__hash__), it is now possible
1875 to explicit block inheritance of hash by setting __hash__=None at
1876 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1877 level.
1878
Nick Coghlanb028f502008-07-13 14:52:36 +00001879- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1880 the parent module cannot be found while performing an absolute import.
1881 This means that an incorrectly defined __package__ attribute will
1882 now only prevent relative imports in that module rather than causing
1883 all imports from that module to fail.

Georg Brandl5cc774e2008-06-11 20:28:06 +00002356 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002357
2358 This is controlled by the configure argument ``--with-universal-archs``:

Georg Brandl3ee81df2008-05-17 18:14:43 +00002418- Issue #1631171: Re-implement the 'warnings' module in C (the
2419 original Python code has been kept as backup). This will allow for
2420 using the 'warning's machinery in such places as the parser where
2421 use of pure Python code is not possible. Both the ``showarning()``
2422 and ``formatwarning()`` gain an optional 'line' argument which is
2423 not called by default for backwards-compatibility reasons. Setting
2424 ``warnings.showwarning()`` to an implementation that lacks support
2425 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002488- Issue #2550: The approach used by client/server code for obtaining
2489 ports to listen on in network-oriented tests has been refined in an
2490 effort to facilitate running multiple instances of the entire
2491 regression test suite in parallel without issue.
2492 test_support.bind_port() has been fixed such that it will always
2493 return a unique port -- which wasn't always the case with the
2494 previous implementation, especially if socket options had been set
2495 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2496 new implementation of bind_port() will actually raise an exception
2497 if it is passed an AF_INET/SOCK_STREAM socket with either the
2498 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2499 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2500 the socket it's been passed. This currently only applies to
2501 Windows. This option prevents any other sockets from binding to the
2502 host/port we've bound to, thus removing the possibility of the
2503 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2504 when a second SOCK_STREAM socket binds and accepts to a host/port
2505 that's already been bound by another socket. The optional preferred
2506 port parameter to bind_port() has been removed. Under no
2507 circumstances should tests be hard coding ports!
2508
2509 test_support.find_unused_port() has also been introduced, which will
2510 pass a temporary socket object to bind_port() in order to obtain an
2511 unused port. The temporary socket object is then closed and
2512 deleted, and the port is returned. This method should only be used
2513 for obtaining an unused port in order to pass to an external program
2514 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2515 a parameter to a server-oriented class that doesn't give you direct
2516 access to the underlying socket used.
2517
2518 Finally, test_support.HOST has been introduced, which should be used
2519 for the host argument of any relevant socket calls (i.e. bind and
2520 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002521
2522 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002523 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002524 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2525 test_asynchat and test_socket_ssl.
2526
Georg Brandl3ee81df2008-05-17 18:14:43 +00002527 It is now possible for multiple instances of the regression test
2528 suite to run in parallel without issue.

2796
Fred Drakea8ee94b2008-03-01 02:45:07 +00002797- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002798 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002799
Georg Brandlad61bc82008-02-23 15:11:18 +00002800- Issue #2067: file.__exit__() now calls subclasses' close() method.
2801
2802- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002803
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002804- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002805 issue 215555 for a discussion.
2806
Eric Smitha73fbe72008-02-23 03:09:44 +00002807- Added the future_builtins module, which contains hex() and oct().
2808 These are the PEP 3127 version of these functions, designed to be
2809 compatible with the hex() and oct() builtins from Python 3.0. They
2810 differ slightly in their output formats from the existing, unchanged
2811 Python 2.6 builtins. The expected usage of the future_builtins
2812 module is:
2813 from future_builtins import hex, oct
2814
Eric Smith7ef40bf2008-02-20 23:34:22 +00002815- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2816 exponents for exponents with absolute value < 100. Follows C99
2817 standard. This is a change on Windows, which would use 3 digits.
2818 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2819 so that any alterations it does to the resulting string will be
2820 available in stringlib/formatter.h (for float.__format__).
2821
Eric Smith5a3c1352008-02-19 13:21:56 +00002822- Implemented PEP 3101, Advanced String Formatting. This adds a new
2823 builtin format(); a format() method for str and unicode; a
2824 __format__() method to object, str, unicode, int, long, float, and
2825 datetime; the class string.Formatter; and the C API
2826 PyObject_Format().
2827
Georg Brandl3ee81df2008-05-17 18:14:43 +00002828- Fixed several potential crashes, all caused by specially crafted
2829 __del__ methods exploiting objects in temporarily inconsistent
2830 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002831
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002832- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002833 prevent a possible crash: an Abstract Base Class would try to access
2834 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002835
Georg Brandl3ee81df2008-05-17 18:14:43 +00002836- Fixed repr() and str() of complex numbers with infinity or nan as
2837 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002838
Georg Brandl3ee81df2008-05-17 18:14:43 +00002839- Clear all free lists during a gc.collect() of the highest generation
2840 in order to allow pymalloc to free more arenas. Python may give back
2841 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002842
Georg Brandl3ee81df2008-05-17 18:14:43 +00002843- Issue #2045: Fix an infinite recursion triggered when printing a
2844 subclass of collections.defaultdict, if its default_factory is set
2845 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002846
Christian Heimesf75dbef2008-02-08 00:11:31 +00002847- Fixed a minor memory leak in dictobject.c. The content of the free
2848 list was not freed on interpreter shutdown.
2849
Georg Brandl5a7eca12010-03-21 19:29:04 +00002850- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00002851 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002852
Georg Brandl3ee81df2008-05-17 18:14:43 +00002853- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2854 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002855 to compact the internal free lists of pre-allocted ints and floats.
2856
Georg Brandl3ee81df2008-05-17 18:14:43 +00002857- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2858 calls. Python expected the return type int but the fork familie
2859 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002860
Georg Brandl3ee81df2008-05-17 18:14:43 +00002861- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2862 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002863
Georg Brandl3ee81df2008-05-17 18:14:43 +00002864- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2865 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002866

Georg Brandl3ee81df2008-05-17 18:14:43 +00002870- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2871 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002872
Georg Brandl3ee81df2008-05-17 18:14:43 +00002873- Patch #1473257: generator objects gain a gi_code attribute. This is
2874 the same object as the func_code attribute of the function that
2875 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002876
Georg Brandl3ee81df2008-05-17 18:14:43 +00002877- Issue #1920: "while 0" statements were completely removed by the
2878 compiler, even in the presence of an "else" clause, which is
2879 supposed to be run when the condition is false. Now the compiler
2880 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002881
Guido van Rossumeead05f2008-01-24 18:21:02 +00002882- A few crashers fixed: weakref_in_del.py (issue #1377858);
2883 loosing_dict_ref.py (issue #1303614, test67.py);
2884 borrowed_ref_[34].py (not in tracker).
2885
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002886- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002887 suppressed while an extension is loaded by calling SetErrorMode in
2888 dynload_win.c. The error is still reported properly.
2889
Georg Brandl3ee81df2008-05-17 18:14:43 +00002890- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002891 several extension methods and modules do not work without unicode
2892 support.
2893
Georg Brandl26543b12008-01-21 18:36:51 +00002894- Issue #1882: when compiling code from a string, encoding cookies in the
2895 second line of code were not always recognized correctly.
2896
Georg Brandl14404b62008-01-19 19:27:05 +00002897- Issue #1679: "0x" was taken as a valid integer literal.
2898
Georg Brandl6caad7d2008-01-26 14:19:22 +00002899- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002900 added.
2901
Christian Heimesc94e2b52008-01-14 04:13:37 +00002902- sys.float_info / PyFloat_GetInfo: The floating point information
2903 object was converted from a dict to a specialized structseq object.
2904
Georg Brandl3ee81df2008-05-17 18:14:43 +00002905- Patch #1816: Added sys.flags structseq. It exposes the status of
2906 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002907
Georg Brandl3ee81df2008-05-17 18:14:43 +00002908- Objects/structseq.c: Implemented new structseq representation. The
2909 patch makes structseqs (e.g. the return value of os.stat) more
2910 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002911
Georg Brandl3ee81df2008-05-17 18:14:43 +00002912- Patch #1700288: added a type attribute cache that caches method

2921 envvar and sys.dont_write_bytecode attribute. All these can be set
2922 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002923
Georg Brandl3ee81df2008-05-17 18:14:43 +00002924- Improve some exception messages when Windows fails to load an
2925 extension module. Now we get for example '%1 is not a valid Win32
2926 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00002933- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002934 and INF. float("nan"), float("inf") and float("-inf") now work on
2935 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002936
Georg Brandl3ee81df2008-05-17 18:14:43 +00002937- Compiler now generates simpler and faster code for dictionary
2938 literals. The oparg for BUILD_MAP now indicates an estimated
2939 dictionary size. There is a new opcode, STORE_MAP, for adding
2940 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002941
Georg Brandl3ee81df2008-05-17 18:14:43 +00002942- Issue #1638: %zd configure test fails on Linux.

2983
Georg Brandl5a7eca12010-03-21 19:29:04 +00002984- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00002985 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2986 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002987
Georg Brandl3ee81df2008-05-17 18:14:43 +00002988- Issue #1686386: Tuple's tp_repr did not take into account the
2989 possibility of having a self-referential tuple, which is possible
2990 from C code. Nor did object's tp_str consider that a type's tp_str
2991 could do something that could lead to an inifinite recursion.
2992 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2993 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002995- Issue #1164: It was possible to trigger deadlock when using the
2996 'print' statement to write to a file since the GIL was not released
2997 as needed. Now PyObject_Print() does the right thing along with
2998 various tp_print implementations of the built-in types and those in
2999 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003009 PyObject_Call() never calling back out to Python code to trigger
3010 recursion depth updates/checks. Required the creation of a static
3011 RuntimeError instance in case normalizing an exception put the
3012 recursion check value past its limit. Fixes crashers

3037
Collin Winter62903052007-05-18 23:11:24 +00003038- except clauses may now be spelled either "except E, target:" or

3060
Guido van Rossum143b5642007-03-23 04:58:42 +00003061- Bug #1683368: The object.__init__() and object.__new__() methods are
3062 now stricter in rejecting excess arguments. The only time when
3063 either allows excess arguments is when it is not overridden and the
3064 other one is. For backwards compatibility, when both are
3065 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003066 warning later). Also, type.__init__() insists on the same signature
3067 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003069- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3070 object to complex using its __complex__() method before falling back
3071 to the __float__() method. Therefore, the functions in the cmath
3072 module now can operate on objects that define a __complex__()
3073 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00003091- Bug #1678647: write a newline after printing an exception in any
3092 case, even when converting the value to a string failed.
3093
Georg Brandl871f1bc2007-03-12 13:17:36 +00003094- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003095 its argument, if it exists. If not, it will work like before. This
3096 allows customizing the output of dir() in the presence of a
3097 __getattr__().

3107 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003108
Georg Brandlaa2321b2007-03-07 00:40:28 +00003109- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003110 makes the filenames the warning module prints much more sensible
3111 when a PYTHONSTARTUP file is used.

3126
Georg Brandl3ee81df2008-05-17 18:14:43 +00003127- When printing an unraisable error, don't print exceptions. before

3695
Georg Brandl92a6bae2007-03-13 17:43:32 +00003696- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003697 are set for invalid interpolation sequences that would lead to

3754 TestCase and TestSuite subclasses (not instances) are no longer
3755 accepted in TestSuite.addTest(). This should cause no

3757 -- the failure just occurred later, with a more cumbersome
3758 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004039- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4040 with RFC 3207 and forgets any knowledge obtained from the server not
4041 obtained from the TLS negotiation itself. Patch contributed by Bill
4042 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004043
Georg Brandl3ee81df2008-05-17 18:14:43 +00004044- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004045 that the SMTP.starttls() caller no longer needs to call ehlo()
4046 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004047 does not claim to support starttls. Adds the
4048 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Raymond Hettinger12e94202007-11-07 01:13:09 +00004132

Georg Brandl3ee81df2008-05-17 18:14:43 +00004147 time so that opening a database previously created with the DB_DUP
4148 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4149 opens. Specifically: dictionary assignment to a DB object will
4150 replace all values for a given key when the database allows
4151 duplicate values. DB users should use DB.put(k, v) when they want
4152 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004153

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004431- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00004432 periodic threadstate and signal checking in tight loops. By
4433 default, this option is turned-off. It should only be enabled in
4434 debugged, performance critical applications.
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004435

4485-----
4486
Georg Brandl3ee81df2008-05-17 18:14:43 +00004487- Unified naming convention for free lists and their limits. All free
4488 lists in Object/ are named ``free_list``, the counter ``numfree``
4489 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4490 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004491
Georg Brandl3ee81df2008-05-17 18:14:43 +00004492- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4493 to ``PyTuple_SetItem``, it can be used to populate a brand new
4494 frozenset; but it does not steal a reference to the added item.

4506
Georg Brandl3ee81df2008-05-17 18:14:43 +00004507- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4508 of w# format code incorrectly truncated the length to an int, even
4509 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4510 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004511
Georg Brandl3ee81df2008-05-17 18:14:43 +00004512- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4532
4533- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4534 outside of pystate.c and should not be necessary.
4535
Georg Brandl3ee81df2008-05-17 18:14:43 +00004536- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4537 absolute imports. In earlier versions they might have used relative
4538 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004539
Georg Brandl3ee81df2008-05-17 18:14:43 +00004540- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4541 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004542
Georg Brandl3ee81df2008-05-17 18:14:43 +00004543- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004568- Removed the macfs module. It had been deprecated since Python 2.5.
4569 This lead to the deprecation of macostools.touched() as it relied
