1276What's New in Python 2.6.1
1277==========================
1278
1279*Release date: 04-Dec-2008*
1280
1281Core and Builtins
1282-----------------
1283
1284- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1285 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1286 instead of throwing a MemoryError.
1287
1288- Issue #4367: Python would segfault during compiling when the unicodedata
1289 module couldn't be imported and \N escapes were present.
1290
1291- Issue #4348: Some bytearray methods returned that didn't cause any change to
1292 the bytearray, returned the same bytearray instead of a copy.
1293
1294- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1295
1296- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1297
1298- Issue #4048: The parser module now correctly validates relative imports.
1299
1300- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1301 exec statement.
1302
1303- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1304 method does not return iterators for the 4th and 5th items.
1305
1306- Issue #4209: Enabling unicode_literals and the print_function in the same
1307 __future__ import didn't work.
1308
1309- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1310 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1311 really executed because I cannot move to such directory on win2k)
1312
1313- Issue #4069: When set.remove(element) is used with a set element, the element
1314 is temporarily replaced with an equivalent frozenset. But the eventual
1315 KeyError would always report the empty frozenset([]) as the missing key. Now
1316 it correctly refers to the initial element.
1317
1318- Fixed C99 style comments in several files. Python is now C89 compatible
1319 again.

1467
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001468- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1469 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1470 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1471 ``printf`` function, whereas PyString_FromFormat has an independent
1472 implementation and uses "%zd" on all platforms for size_t values.
1473 This makes a difference on win64, where ``printf`` needs "%Id" to display
1474 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001476- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Vinay Sajip35e3b032008-09-01 14:33:59 +00001493- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001494 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1495 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1496 when given a tuple of classes as second argument, were looking up
1497 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1498 type object.

1591-----------------
1592
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001593- Issue #2975: When compiling several extension modules with Visual Studio 2008
1594 from the same python interpreter, some environment variables would grow
1595 without limit.
1596
Benjamin Peterson37346b22008-08-23 20:27:43 +00001597- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
1598 exploitation of poor argument checking.
1599
Gerhard Häringef2276b2008-09-12 13:54:06 +00001600- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
1601
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00001602- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
1603 remaining ones have "pysqlite_" prefix.
1604
Gerhard Häringe6872eb2008-09-12 22:33:22 +00001605- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

1611
Nick Coghland2e09382008-09-11 12:11:06 +00001612- Issue #3781: Add test.test_support.check_warnings() as a convenience
1613 wrapper for warnings.catch_warnings() that makes it easier to check
1614 that expected warning messages are being reported.
1615
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00001616- Issue #3796: Some tests functions were not enabled in test_float.
1617

Martin v. Löwisab0b29b2008-09-13 08:11:57 +00001623- Issue #3833: Use a different upgrade code for Win64 installers.
1624
Martin v. Löwis3f5fda82008-09-08 13:50:10 +00001625- Issue #2271: Set SecureCustomProperties so that installation will properly

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001634What's New in Python 2.6 beta 3?
1635================================
1636
Barry Warsaw07a4a382008-08-21 01:15:08 +00001637*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001638
1639Core and Builtins
1640-----------------
1641
Guido van Rossumf8402962008-08-20 15:01:50 +00001642- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1643 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1644 extensions do not automatically benefit from the class attribute
1645 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1646 to their tp_flags field if they care. This is a backwards
1647 compatibility feature; in 3.0, all types will use the cache by
1648 default.
1649
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001650- Keyword arguments can now follow starred arguments. (``f(a, *args,
1651 keyword=23)`` is now valid syntax.)
1652
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001653- ctypes function pointers that are COM methods have a boolean True
1654 value again.
1655
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001656- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1657 by denying s# to parse objects that have a releasebuffer procedure,
1658 and introducing s*.
1659
Georg Brandl1e13ea92008-08-11 09:07:59 +00001660- Issue #3537: Fix an assertion failure when an empty but presized dict
1661 object was stored in the freelist.
1662
Mark Dickinsonb6467572008-08-04 21:30:09 +00001663- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1664 ValueError consistently across platforms.
1665
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001666- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1667 (64bit Unix, for example), unichr() would truncate its argument and return
1668 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1669
Neal Norwitze7d8be82008-07-31 17:17:14 +00001670- Apply security patches from Apple.
1671
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001672- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1673 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1674
Antoine Pitrou92f82162008-07-25 22:22:08 +00001675- Issue #1819: function calls with several named parameters are now on
1676 average 35% faster (as measured by pybench).
1677
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001678- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1679 the python debugger steps into a class statement: the free variables (local
1680 variables defined in an outer scope) would be deleted from the outer scope.
1681
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001682- Issue #2620: Overflow checking when allocating or reallocating memory
1683 was not always being done properly in some python types and extension
1684 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1685 all been updated to perform better checks and places in the code that
1686 would previously leak memory on the error path when such an allocation
1687 failed have been fixed.
1688
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001689Library
1690-------
1691
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001692- Issue #3612: Added some missing basic types in ctypes.wintypes.
1693
Benjamin Petersone977ad42008-08-20 01:42:01 +00001694- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1695 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1696
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001697- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1698 version reported by these tools does not necessarily follow the python
1699 version numbering scheme, so the module is less strict when parsing it.
1700
Nick Coghlanf70385a2008-08-18 12:42:46 +00001701- Issue #2235: Added Py3k warnings for types which will become unhashable
1702 under the stricter __hash__ inheritance rules in 3.0. Several types
1703 which did not meet the rules for hash invariants and were already
1704 unhashable in 3.0 have now been explicitly flagged as unhashable in
1705 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1706 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1707
Brett Cannon88f801d2008-08-18 00:46:22 +00001708- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1709 imported into the module but exposed as part of the module's API.
1710
Brett Cannon7b96f072008-08-18 00:41:11 +00001711- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1712
Brett Cannon46225e72008-08-18 00:36:52 +00001713- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1714
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001715- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1716
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001717- Issue #3575: Incremental decoder's decode function now takes bytearray
1718 by using 's*' instead of 't#'.
1719
Jesus Cea585ad8a2009-07-02 15:37:21 +00001720- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001721 fails unicode conversion on 2nd parameter. (windows only)
1722
Facundo Batista94f243a2008-08-17 03:38:39 +00001723- Issue 2464. urllib2 now supports a malformation in the URL received
1724 in a redirect.
1725
Brett Cannonabe423e2008-08-16 21:47:07 +00001726- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001727 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001728
Facundo Batistaeb90b782008-08-16 14:44:07 +00001729- Issue #2776: fixed small issue when handling an URL with double slash
1730 after a 302 response in the case of not going through a proxy.
1731
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001732- Issue #2676: in the email package, content-type parsing was hanging on
1733 pathological input because of quadratic or exponential behaviour of a
1734 regular expression.
1735
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001736- Issue #3476: binary buffered reading through the new "io" library is now
1737 thread-safe.
1738
Brett Cannonbf3157b2008-08-14 05:00:03 +00001739- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1740 since mimetools itself is deprecated. Because modules are cached, all
1741 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1742
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001743- Issue #3134: shutil referenced undefined WindowsError symbol.
1744
Robert Schuppenies14646332008-08-10 11:01:53 +00001745- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1746 menu entries were not deleted.
1747
Brett Cannon83e81842008-08-09 23:30:55 +00001748- Copied the implementation of reduce() to _functools.reduce() to have a
1749 version that did not raise a DeprecationWarning under -3.
1750
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001751- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1752 a MemoryError rather than silently stop the iteration.
1753
Guido van Rossum59ce9012008-08-09 14:55:34 +00001754- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1755 to _sre.compile() will now be rejected. This should not affect anybody
1756 since the re.compile() function never generates invalid re-bytecode.
1757
Skip Montanaroa032bf42008-08-08 22:52:51 +00001758- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1759 upon first access it can be automatically initialized from the csv file if
1760 it wasn't initialized during instantiation.
1761
Brett Cannon3aa2a492008-08-06 22:28:09 +00001762- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1763 the reload() built-in has been removed.
1764
Brett Cannon7e30b672008-08-04 21:52:25 +00001765- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001766 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00001767 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
1768 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
1769 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
1770 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1771 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00001772
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001773- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1774 raised an AttributeError.
1775
Benjamin Peterson01a24322008-07-28 23:35:27 +00001776- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001777 asking for a specific length. This problem only affected files opened
1778 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001779
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001780- Issue #3449: Update decimal module to use most recent specification
1781 (v. 1.68) and tests (v. 2.58) from IBM.
1782
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001783- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
1784
Raymond Hettinger8c664e82008-07-25 18:43:33 +00001785- Issue 1592: Improve error reporting when operations are attempted
1786 on a closed shelf.

1789
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001790- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
1791
1792- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1793 invalid arguments.
1794
1795- Issue #3302: Fix several crashes when calling locale's gettext functions
1796 with None arguments.
1797
1798- Issue #3389: Allow resolving dotted names for handlers in logging
1799 configuration files.
1800
1801- Deprecate the sunaudio module for removal in Python 3.0.
1802
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001803- Issue #3394: zipfile.writestr sets external attributes when passed a
1804 file name rather than a ZipInfo instance, so files are extracted with
1805 mode 0600 rather than 000 under Unix.
1806
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001807- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1808 argument in python 2.5, this broke code that subclassed Popen to include its
1809 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001816Documentation
1817-------------
1818
Nick Coghlan6e8fef02008-08-18 13:14:22 +00001819- Issue #2235: the C API function PyObject_HashNotImplemented and its
1820 interaction with the tp_hash slot (added in 2.6b2) are now documented
1821
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001822- Issue #643841: The language reference now provides more detailed
1823 coverage of the lookup process for special methods. The disclaimers
1824 regarding lack of coverage of new-style classes have also been
1825 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001828What's New in Python 2.6 beta 2?
1829================================
1830
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001831*Release date: 17-Jul-2008*
1832
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001833Core and Builtins
1834-----------------
1835
Georg Brandl3e483f62008-07-16 22:57:41 +00001836- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1837 its methods now allow for items objects that can be converted to
1838 an integer using operator.index().
1839
Mark Dickinson64b7e502008-07-16 09:40:03 +00001840- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1841 produced a ValueError instead of giving the correct float.
1842
Eric Smitha5fa5a22008-07-16 00:11:49 +00001843- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1844 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1845
Mark Dickinson7103aa42008-07-15 19:08:33 +00001846- Issue #3008: the float type has a new instance method 'float.hex'
1847 and a new class method 'float.fromhex' to convert floating-point
1848 numbers to and from hexadecimal strings, respectively.
1849
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001850- Issue #2235: __hash__ is once again inherited by default. To allow
1851 collections.Hashable to remain meaningful in the presence of the
1852 default hash implementation (object.__hash__), it is now possible
1853 to explicit block inheritance of hash by setting __hash__=None at
1854 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1855 level.
1856
Nick Coghlanb028f502008-07-13 14:52:36 +00001857- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1858 the parent module cannot be found while performing an absolute import.
1859 This means that an incorrectly defined __package__ attribute will
1860 now only prevent relative imports in that module rather than causing
1861 all imports from that module to fail.
1862
Nick Coghlan14ff9942008-07-08 14:21:42 +00001863- Issue #2517: Allow unicode messages in Exceptions again by correctly
1864 bypassing the instance dictionary when looking up __unicode__ on
1865 new-style classes.
1866
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001867- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1868 set to a custom object whose write() method happens to install
1869 another file in sys.stdout.
1870
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001871- Issue #3088: Corrected a race condition in classes derived from
1872 threading.local: the first member set by a thread could be saved in
1873 another thread's dictionary.
1874
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001875- Issue #3004: Minor change to slice.indices(): the start and stop
1876 arguments are now treated identically, making the behaviour easier
1877 to describe and understand. For example, slice(None, -10,
1878 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1879 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1880 10, -1).
1881
Georg Brandl278fc502008-07-19 12:46:12 +00001882- Issue #3219: Calling a function with repeated keyword arguments,

Georg Brandl5cc774e2008-06-11 20:28:06 +00002334 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002335
2336 This is controlled by the configure argument ``--with-universal-archs``:

2339
2340 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2341
2342 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit

Georg Brandl3ee81df2008-05-17 18:14:43 +00002396- Issue #1631171: Re-implement the 'warnings' module in C (the
2397 original Python code has been kept as backup). This will allow for
2398 using the 'warning's machinery in such places as the parser where
2399 use of pure Python code is not possible. Both the ``showarning()``
2400 and ``formatwarning()`` gain an optional 'line' argument which is
2401 not called by default for backwards-compatibility reasons. Setting
2402 ``warnings.showwarning()`` to an implementation that lacks support
2403 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002466- Issue #2550: The approach used by client/server code for obtaining
2467 ports to listen on in network-oriented tests has been refined in an
2468 effort to facilitate running multiple instances of the entire
2469 regression test suite in parallel without issue.
2470 test_support.bind_port() has been fixed such that it will always
2471 return a unique port -- which wasn't always the case with the
2472 previous implementation, especially if socket options had been set
2473 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2474 new implementation of bind_port() will actually raise an exception
2475 if it is passed an AF_INET/SOCK_STREAM socket with either the
2476 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2477 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2478 the socket it's been passed. This currently only applies to
2479 Windows. This option prevents any other sockets from binding to the
2480 host/port we've bound to, thus removing the possibility of the
2481 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2482 when a second SOCK_STREAM socket binds and accepts to a host/port
2483 that's already been bound by another socket. The optional preferred
2484 port parameter to bind_port() has been removed. Under no
2485 circumstances should tests be hard coding ports!
2486
2487 test_support.find_unused_port() has also been introduced, which will
2488 pass a temporary socket object to bind_port() in order to obtain an
2489 unused port. The temporary socket object is then closed and
2490 deleted, and the port is returned. This method should only be used
2491 for obtaining an unused port in order to pass to an external program
2492 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2493 a parameter to a server-oriented class that doesn't give you direct
2494 access to the underlying socket used.
2495
2496 Finally, test_support.HOST has been introduced, which should be used
2497 for the host argument of any relevant socket calls (i.e. bind and
2498 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002499
2500 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002501 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002502 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2503 test_asynchat and test_socket_ssl.
2504
Georg Brandl3ee81df2008-05-17 18:14:43 +00002505 It is now possible for multiple instances of the regression test
2506 suite to run in parallel without issue.

Thomas Heller78b8f442008-03-05 14:53:39 +00002710- The bundled libffi copy is now in sync with the recently released
2711 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002712 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
2713 files are used. On all linux systems the --with-system-ffi

2774
Fred Drakea8ee94b2008-03-01 02:45:07 +00002775- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002776 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00002778- Issue #2067: file.__exit__() now calls subclasses' close() method.
2779
2780- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002781
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002782- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002783 issue 215555 for a discussion.
2784
Eric Smitha73fbe72008-02-23 03:09:44 +00002785- Added the future_builtins module, which contains hex() and oct().
2786 These are the PEP 3127 version of these functions, designed to be
2787 compatible with the hex() and oct() builtins from Python 3.0. They
2788 differ slightly in their output formats from the existing, unchanged
2789 Python 2.6 builtins. The expected usage of the future_builtins
2790 module is:
2791 from future_builtins import hex, oct
2792
Eric Smith7ef40bf2008-02-20 23:34:22 +00002793- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2794 exponents for exponents with absolute value < 100. Follows C99
2795 standard. This is a change on Windows, which would use 3 digits.
2796 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2797 so that any alterations it does to the resulting string will be
2798 available in stringlib/formatter.h (for float.__format__).
2799
Eric Smith5a3c1352008-02-19 13:21:56 +00002800- Implemented PEP 3101, Advanced String Formatting. This adds a new
2801 builtin format(); a format() method for str and unicode; a
2802 __format__() method to object, str, unicode, int, long, float, and
2803 datetime; the class string.Formatter; and the C API
2804 PyObject_Format().
2805
Georg Brandl3ee81df2008-05-17 18:14:43 +00002806- Fixed several potential crashes, all caused by specially crafted
2807 __del__ methods exploiting objects in temporarily inconsistent
2808 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002809
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002810- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002811 prevent a possible crash: an Abstract Base Class would try to access
2812 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002813
Georg Brandl3ee81df2008-05-17 18:14:43 +00002814- Fixed repr() and str() of complex numbers with infinity or nan as
2815 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002816
Georg Brandl3ee81df2008-05-17 18:14:43 +00002817- Clear all free lists during a gc.collect() of the highest generation
2818 in order to allow pymalloc to free more arenas. Python may give back
2819 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002820
Georg Brandl3ee81df2008-05-17 18:14:43 +00002821- Issue #2045: Fix an infinite recursion triggered when printing a
2822 subclass of collections.defaultdict, if its default_factory is set
2823 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002824
Christian Heimesf75dbef2008-02-08 00:11:31 +00002825- Fixed a minor memory leak in dictobject.c. The content of the free
2826 list was not freed on interpreter shutdown.
2827
Georg Brandl5a7eca12010-03-21 19:29:04 +00002828- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00002829 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002830
Georg Brandl3ee81df2008-05-17 18:14:43 +00002831- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2832 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002833 to compact the internal free lists of pre-allocted ints and floats.
2834
Georg Brandl3ee81df2008-05-17 18:14:43 +00002835- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2836 calls. Python expected the return type int but the fork familie
2837 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002838
Georg Brandl3ee81df2008-05-17 18:14:43 +00002839- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2840 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002841
Georg Brandl3ee81df2008-05-17 18:14:43 +00002842- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2843 with the collections.Sequence API.

2849 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002850
Georg Brandl3ee81df2008-05-17 18:14:43 +00002851- Patch #1473257: generator objects gain a gi_code attribute. This is
2852 the same object as the func_code attribute of the function that
2853 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002854
Georg Brandl3ee81df2008-05-17 18:14:43 +00002855- Issue #1920: "while 0" statements were completely removed by the
2856 compiler, even in the presence of an "else" clause, which is
2857 supposed to be run when the condition is false. Now the compiler
2858 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002859
Guido van Rossumeead05f2008-01-24 18:21:02 +00002860- A few crashers fixed: weakref_in_del.py (issue #1377858);
2861 loosing_dict_ref.py (issue #1303614, test67.py);
2862 borrowed_ref_[34].py (not in tracker).
2863
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002864- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002865 suppressed while an extension is loaded by calling SetErrorMode in
2866 dynload_win.c. The error is still reported properly.
2867
Georg Brandl3ee81df2008-05-17 18:14:43 +00002868- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002869 several extension methods and modules do not work without unicode
2870 support.
2871
Georg Brandl26543b12008-01-21 18:36:51 +00002872- Issue #1882: when compiling code from a string, encoding cookies in the
2873 second line of code were not always recognized correctly.
2874
Georg Brandl14404b62008-01-19 19:27:05 +00002875- Issue #1679: "0x" was taken as a valid integer literal.
2876
Georg Brandl6caad7d2008-01-26 14:19:22 +00002877- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002878 added.
2879
Christian Heimesc94e2b52008-01-14 04:13:37 +00002880- sys.float_info / PyFloat_GetInfo: The floating point information
2881 object was converted from a dict to a specialized structseq object.
2882
Georg Brandl3ee81df2008-05-17 18:14:43 +00002883- Patch #1816: Added sys.flags structseq. It exposes the status of
2884 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002885
Georg Brandl3ee81df2008-05-17 18:14:43 +00002886- Objects/structseq.c: Implemented new structseq representation. The
2887 patch makes structseqs (e.g. the return value of os.stat) more
2888 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002889
Georg Brandl3ee81df2008-05-17 18:14:43 +00002890- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00002912 and INF. float("nan"), float("inf") and float("-inf") now work on
2913 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002914
Georg Brandl3ee81df2008-05-17 18:14:43 +00002915- Compiler now generates simpler and faster code for dictionary
2916 literals. The oparg for BUILD_MAP now indicates an estimated
2917 dictionary size. There is a new opcode, STORE_MAP, for adding
2918 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002947- Patch #1739468: Directories and zipfiles containing a __main__.py
2948 file can now be directly executed by passing their name to the
2949 interpreter. The directory/zipfile is automatically inserted as the
2950 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002952- Issue #1265: Fix a problem with sys.settrace, if the tracing
2953 function uses a generator expression when at the same time the
2954 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002955
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002956- sets and frozensets now have an isdisjoint() method.
2957

2959
Neal Norwitz44f326e2007-10-05 05:29:17 +00002960- Fix warnings found by the new version of the Coverity checker.
2961
Georg Brandl5a7eca12010-03-21 19:29:04 +00002962- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00002963 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2964 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002965
Georg Brandl3ee81df2008-05-17 18:14:43 +00002966- Issue #1686386: Tuple's tp_repr did not take into account the
2967 possibility of having a self-referential tuple, which is possible
2968 from C code. Nor did object's tp_str consider that a type's tp_str
2969 could do something that could lead to an inifinite recursion.
2970 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2971 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002972
Georg Brandl3ee81df2008-05-17 18:14:43 +00002973- Issue #1164: It was possible to trigger deadlock when using the
2974 'print' statement to write to a file since the GIL was not released
2975 as needed. Now PyObject_Print() does the right thing along with
2976 various tp_print implementations of the built-in types and those in
2977 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002978
Georg Brandl3ee81df2008-05-17 18:14:43 +00002979- Issue #1147: Exceptions were directly allowing string exceptions in
2980 their throw() method even though string exceptions no longer
2981 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002982
Georg Brandl3ee81df2008-05-17 18:14:43 +00002983- Issue #1096: Prevent a segfault from getting the repr of a very
2984 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002985
Brett Cannon1e534b52007-09-07 04:18:30 +00002986- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002987 PyObject_Call() never calling back out to Python code to trigger
2988 recursion depth updates/checks. Required the creation of a static
2989 RuntimeError instance in case normalizing an exception put the
2990 recursion check value past its limit. Fixes crashers
2991 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002992
Georg Brandl3ee81df2008-05-17 18:14:43 +00002993- Patch #1031213: Decode source line in SyntaxErrors back to its

Georg Brandla5ea6892007-06-01 11:33:33 +00003005
Neal Norwitz0ac60192007-05-27 04:08:54 +00003006- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003007 __*__ attributes. (Some already existed, e.g., __doc__ and
3008 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003009
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003010- Add -3 option to the interpreter to warn about features that are
3011 deprecated and will be changed/removed in Python 3.0.
3012
Georg Brandl2134e752007-05-21 20:34:16 +00003013- Patch #1686487: you can now pass any mapping after '**' in function
3014 calls.
3015
Collin Winter62903052007-05-18 23:11:24 +00003016- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003017 "except E as target:". This is to provide forwards compatibility
3018 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003019
Brett Cannon229cee22007-05-05 01:34:02 +00003020- Deprecate BaseException.message as per PEP 352.
3021
Georg Brandl3ee81df2008-05-17 18:14:43 +00003022- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003023 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003024
Vinay Sajip8549ce32007-05-06 17:53:37 +00003025- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003026 setting a plain string, ie don't expand to single letter identifiers.
3027
Raymond Hettinger13936692007-04-11 18:40:58 +00003028- Request #1191699: Slices can now be pickled.
3029
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003030- Request #1193128: str.translate() now allows a None argument for
3031 translations that only remove characters without re-mapping the
3032 remaining characters.
3033
Georg Brandl5cb76c12007-03-21 09:00:39 +00003034- Patch #1682205: a TypeError while unpacking an iterable is no longer
3035 masked by a generic one with the message "unpack non-sequence".
3036
Neal Norwitzaa754b72007-03-21 06:39:48 +00003037- Remove unused file Python/fmod.c.
3038
Guido van Rossum143b5642007-03-23 04:58:42 +00003039- Bug #1683368: The object.__init__() and object.__new__() methods are
3040 now stricter in rejecting excess arguments. The only time when
3041 either allows excess arguments is when it is not overridden and the
3042 other one is. For backwards compatibility, when both are
3043 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003044 warning later). Also, type.__init__() insists on the same signature
3045 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003046
Georg Brandl3ee81df2008-05-17 18:14:43 +00003047- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3048 object to complex using its __complex__() method before falling back
3049 to the __float__() method. Therefore, the functions in the cmath
3050 module now can operate on objects that define a __complex__()
3051 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003052
Georg Brandl3ee81df2008-05-17 18:14:43 +00003053- Patch #1623563: allow __class__ assignment for classes with
3054 __slots__. The old and the new class are still required to have the
3055 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003056

3061 ``object.__reduce_ex__()`` is called with an object that is faking
3062 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003063
Georg Brandl3ee81df2008-05-17 18:14:43 +00003064- Patch #1680015: Don't modify __slots__ tuple if it contains an

3068
Georg Brandl7b9c5552007-03-12 14:30:05 +00003069- Bug #1678647: write a newline after printing an exception in any
3070 case, even when converting the value to a string failed.
3071
Georg Brandl871f1bc2007-03-12 13:17:36 +00003072- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003073 its argument, if it exists. If not, it will work like before. This
3074 allows customizing the output of dir() in the presence of a
3075 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003076
Collin Winter276887b2007-03-12 16:11:39 +00003077- Patch #922167: Python no longer segfaults when faced with infinitely
3078 self-recursive reload() calls (as reported by bug #742342).
3079
Georg Brandl3ee81df2008-05-17 18:14:43 +00003080- Patch #1675981: remove unreachable code from ``type.__new__()``
3081 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003083- Patch #1491866: change the complex() constructor to allow
3084 parthensized forms. This means complex(repr(x)) now works instead of
3085 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003086
Georg Brandlaa2321b2007-03-07 00:40:28 +00003087- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003088 makes the filenames the warning module prints much more sensible
3089 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003090
Georg Brandl49aafc92007-03-07 00:34:46 +00003091- Variant of patch #697613: don't exit the interpreter on a SystemExit
3092 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003093 variable is given, but break into the interactive interpreter just
3094 like on other exceptions or normal program exit.

3100 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00003101
Georg Brandl0fca97a2007-03-05 22:28:08 +00003102- Patch #1674228: when assigning a slice (old-style), check for the
3103 sq_ass_slice instead of the sq_slice slot.
3104
Georg Brandl3ee81df2008-05-17 18:14:43 +00003105- When printing an unraisable error, don't print exceptions. before
3106 the name. This duplicates the behavior whening normally printing
3107 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003109- Bug #1653736: Properly discard third argument to

3735 -- the failure just occurred later, with a more cumbersome
3736 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004017- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4018 with RFC 3207 and forgets any knowledge obtained from the server not
4019 obtained from the TLS negotiation itself. Patch contributed by Bill
4020 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004021
Georg Brandl3ee81df2008-05-17 18:14:43 +00004022- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004023 that the SMTP.starttls() caller no longer needs to call ehlo()
4024 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004025 does not claim to support starttls. Adds the
4026 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4107 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4108 silently miscode subclasses of those types. Now, it raises a
4109 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004110

Georg Brandl3ee81df2008-05-17 18:14:43 +00004125 time so that opening a database previously created with the DB_DUP
4126 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4127 opens. Specifically: dictionary assignment to a DB object will
4128 replace all values for a given key when the database allows
4129 duplicate values. DB users should use DB.put(k, v) when they want
4130 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004131

4137 characters with ASCII value less than 32. Also, it correctly quotes
4138 dots only if they occur on a single line, as opposed to the previous
4139 behavior of quoting dots if they are the second character of any
4140 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004141

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004409- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00004410 periodic threadstate and signal checking in tight loops. By
4411 default, this option is turned-off. It should only be enabled in
4412 debugged, performance critical applications.

Christian Heimes5b970ad2008-02-06 13:33:44 +00004469
Georg Brandl3ee81df2008-05-17 18:14:43 +00004470- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4471 to ``PyTuple_SetItem``, it can be used to populate a brand new

4484
Georg Brandl3ee81df2008-05-17 18:14:43 +00004485- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4486 of w# format code incorrectly truncated the length to an int, even
4487 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4488 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004489
Georg Brandl3ee81df2008-05-17 18:14:43 +00004490- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4512 outside of pystate.c and should not be necessary.
4513
Georg Brandl3ee81df2008-05-17 18:14:43 +00004514- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4515 absolute imports. In earlier versions they might have used relative
4516 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004517
Georg Brandl3ee81df2008-05-17 18:14:43 +00004518- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4519 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004520
Georg Brandl3ee81df2008-05-17 18:14:43 +00004521- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

4531 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004532

Georg Brandl3ee81df2008-05-17 18:14:43 +00004546- Removed the macfs module. It had been deprecated since Python 2.5.
4547 This lead to the deprecation of macostools.touched() as it relied
4548 solely on macfs and was a no-op under OS X.
