1278 module couldn't be imported and \N escapes were present.

1298- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1299 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1300 really executed because I cannot move to such directory on win2k)

1456
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001457- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1458 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1459 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1460 ``printf`` function, whereas PyString_FromFormat has an independent
1461 implementation and uses "%zd" on all platforms for size_t values.
1462 This makes a difference on win64, where ``printf`` needs "%Id" to display
1463 64bit values.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001480 was correctly parsed but parsing of subsequent arguments failed.

Vinay Sajip35e3b032008-09-01 14:33:59 +00001482- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001483 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1484 mechanism. In the process, fix a bug where isinstance() and issubclass(),

1486 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1487 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001623What's New in Python 2.6 beta 3?
1624================================
1625
Barry Warsaw07a4a382008-08-21 01:15:08 +00001626*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001627
1628Core and Builtins
1629-----------------
1630
Guido van Rossumf8402962008-08-20 15:01:50 +00001631- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1632 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1633 extensions do not automatically benefit from the class attribute
1634 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1635 to their tp_flags field if they care. This is a backwards
1636 compatibility feature; in 3.0, all types will use the cache by
1637 default.
1638
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001639- Keyword arguments can now follow starred arguments. (``f(a, *args,
1640 keyword=23)`` is now valid syntax.)
1641
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001642- ctypes function pointers that are COM methods have a boolean True
1643 value again.
1644
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001645- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1646 by denying s# to parse objects that have a releasebuffer procedure,
1647 and introducing s*.
1648
Georg Brandl1e13ea92008-08-11 09:07:59 +00001649- Issue #3537: Fix an assertion failure when an empty but presized dict
1650 object was stored in the freelist.
1651
Mark Dickinsonb6467572008-08-04 21:30:09 +00001652- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1653 ValueError consistently across platforms.
1654
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001655- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1656 (64bit Unix, for example), unichr() would truncate its argument and return
1657 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1658
Neal Norwitze7d8be82008-07-31 17:17:14 +00001659- Apply security patches from Apple.
1660
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001661- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1662 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1663
Antoine Pitrou92f82162008-07-25 22:22:08 +00001664- Issue #1819: function calls with several named parameters are now on
1665 average 35% faster (as measured by pybench).
1666
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001667- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1668 the python debugger steps into a class statement: the free variables (local
1669 variables defined in an outer scope) would be deleted from the outer scope.
1670
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001671- Issue #2620: Overflow checking when allocating or reallocating memory
1672 was not always being done properly in some python types and extension
1673 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1674 all been updated to perform better checks and places in the code that
1675 would previously leak memory on the error path when such an allocation
1676 failed have been fixed.
1677
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001678Library
1679-------
1680
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001681- Issue #3612: Added some missing basic types in ctypes.wintypes.
1682
Benjamin Petersone977ad42008-08-20 01:42:01 +00001683- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1684 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1685
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001686- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1687 version reported by these tools does not necessarily follow the python
1688 version numbering scheme, so the module is less strict when parsing it.
1689
Nick Coghlanf70385a2008-08-18 12:42:46 +00001690- Issue #2235: Added Py3k warnings for types which will become unhashable
1691 under the stricter __hash__ inheritance rules in 3.0. Several types
1692 which did not meet the rules for hash invariants and were already
1693 unhashable in 3.0 have now been explicitly flagged as unhashable in
1694 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1695 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1696
Brett Cannon88f801d2008-08-18 00:46:22 +00001697- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1698 imported into the module but exposed as part of the module's API.
1699
Brett Cannon7b96f072008-08-18 00:41:11 +00001700- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1701
Brett Cannon46225e72008-08-18 00:36:52 +00001702- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1703
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001704- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1705
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001706- Issue #3575: Incremental decoder's decode function now takes bytearray
1707 by using 's*' instead of 't#'.
1708
Jesus Cea585ad8a2009-07-02 15:37:21 +00001709- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001710 fails unicode conversion on 2nd parameter. (windows only)
1711
Facundo Batista94f243a2008-08-17 03:38:39 +00001712- Issue 2464. urllib2 now supports a malformation in the URL received
1713 in a redirect.
1714
Brett Cannonabe423e2008-08-16 21:47:07 +00001715- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001716 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001717
Facundo Batistaeb90b782008-08-16 14:44:07 +00001718- Issue #2776: fixed small issue when handling an URL with double slash
1719 after a 302 response in the case of not going through a proxy.
1720
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001721- Issue #2676: in the email package, content-type parsing was hanging on
1722 pathological input because of quadratic or exponential behaviour of a
1723 regular expression.
1724
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001725- Issue #3476: binary buffered reading through the new "io" library is now
1726 thread-safe.
1727
Brett Cannonbf3157b2008-08-14 05:00:03 +00001728- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1729 since mimetools itself is deprecated. Because modules are cached, all
1730 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1731
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001732- Issue #3134: shutil referenced undefined WindowsError symbol.
1733
Robert Schuppenies14646332008-08-10 11:01:53 +00001734- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1735 menu entries were not deleted.
1736
Brett Cannon83e81842008-08-09 23:30:55 +00001737- Copied the implementation of reduce() to _functools.reduce() to have a
1738 version that did not raise a DeprecationWarning under -3.
1739
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001740- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1741 a MemoryError rather than silently stop the iteration.
1742
Guido van Rossum59ce9012008-08-09 14:55:34 +00001743- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1744 to _sre.compile() will now be rejected. This should not affect anybody
1745 since the re.compile() function never generates invalid re-bytecode.
1746
Skip Montanaroa032bf42008-08-08 22:52:51 +00001747- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1748 upon first access it can be automatically initialized from the csv file if
1749 it wasn't initialized during instantiation.
1750
Brett Cannon3aa2a492008-08-06 22:28:09 +00001751- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1752 the reload() built-in has been removed.
1753
Brett Cannon7e30b672008-08-04 21:52:25 +00001754- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001755 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1759 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1760 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.

Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001762- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1763 raised an AttributeError.
1764
Benjamin Peterson01a24322008-07-28 23:35:27 +00001765- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001766 asking for a specific length. This problem only affected files opened
1767 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001768
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001769- Issue #3449: Update decimal module to use most recent specification
1770 (v. 1.68) and tests (v. 2.58) from IBM.
1771
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001772- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
1773

1780
1781- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1782 invalid arguments.
1783
1784- Issue #3302: Fix several crashes when calling locale's gettext functions
1785 with None arguments.
1786
1787- Issue #3389: Allow resolving dotted names for handlers in logging
1788 configuration files.
1789
1790- Deprecate the sunaudio module for removal in Python 3.0.
1791
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001792- Issue #3394: zipfile.writestr sets external attributes when passed a
1793 file name rather than a ZipInfo instance, so files are extracted with
1794 mode 0600 rather than 000 under Unix.
1795
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001796- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1797 argument in python 2.5, this broke code that subclassed Popen to include its
1798 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001808- Issue #2235: the C API function PyObject_HashNotImplemented and its
1809 interaction with the tp_hash slot (added in 2.6b2) are now documented
1810
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001811- Issue #643841: The language reference now provides more detailed
1812 coverage of the lookup process for special methods. The disclaimers
1813 regarding lack of coverage of new-style classes have also been
1814 removed, since the coverage is now fairly reasonable.

1823-----------------
1824
Georg Brandl3e483f62008-07-16 22:57:41 +00001825- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1826 its methods now allow for items objects that can be converted to
1827 an integer using operator.index().
1828
Mark Dickinson64b7e502008-07-16 09:40:03 +00001829- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1830 produced a ValueError instead of giving the correct float.
1831
Eric Smitha5fa5a22008-07-16 00:11:49 +00001832- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1833 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1834
Mark Dickinson7103aa42008-07-15 19:08:33 +00001835- Issue #3008: the float type has a new instance method 'float.hex'
1836 and a new class method 'float.fromhex' to convert floating-point
1837 numbers to and from hexadecimal strings, respectively.
1838
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001839- Issue #2235: __hash__ is once again inherited by default. To allow
1840 collections.Hashable to remain meaningful in the presence of the
1841 default hash implementation (object.__hash__), it is now possible
1842 to explicit block inheritance of hash by setting __hash__=None at
1843 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1844 level.
1845
Nick Coghlanb028f502008-07-13 14:52:36 +00001846- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1847 the parent module cannot be found while performing an absolute import.
1848 This means that an incorrectly defined __package__ attribute will
1849 now only prevent relative imports in that module rather than causing
1850 all imports from that module to fail.
1851
Nick Coghlan14ff9942008-07-08 14:21:42 +00001852- Issue #2517: Allow unicode messages in Exceptions again by correctly
1853 bypassing the instance dictionary when looking up __unicode__ on
1854 new-style classes.
1855
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001856- Issue #3242: Fix a crash inside the print statement, if sys.stdout is

1862 another thread's dictionary.
1863
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001864- Issue #3004: Minor change to slice.indices(): the start and stop
1865 arguments are now treated identically, making the behaviour easier
1866 to describe and understand. For example, slice(None, -10,
1867 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1868 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1869 10, -1).

Georg Brandl5cc774e2008-06-11 20:28:06 +00002323 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002324
2325 This is controlled by the configure argument ``--with-universal-archs``:
2326
2327 - ``--with-universal-archs=all``: install 4-way universal
2328
2329 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2330
2331 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2332
2333 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002385- Issue #1631171: Re-implement the 'warnings' module in C (the
2386 original Python code has been kept as backup). This will allow for
2387 using the 'warning's machinery in such places as the parser where
2388 use of pure Python code is not possible. Both the ``showarning()``
2389 and ``formatwarning()`` gain an optional 'line' argument which is
2390 not called by default for backwards-compatibility reasons. Setting
2391 ``warnings.showwarning()`` to an implementation that lacks support
2392 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002417- The getpass module has been improved on Unix. It now uses /dev/tty
2418 by default and uses stderr instead of stdout. A GetPassWarning is
2419 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002447- Issue #2385: distutils.core.run_script() makes __file__ available,
2448 so the controlled environment will more closely mirror the typical
2449 script environment. This supports setup.py scripts that refer to
2450 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002455- Issue #2550: The approach used by client/server code for obtaining
2456 ports to listen on in network-oriented tests has been refined in an
2457 effort to facilitate running multiple instances of the entire
2458 regression test suite in parallel without issue.
2459 test_support.bind_port() has been fixed such that it will always
2460 return a unique port -- which wasn't always the case with the
2461 previous implementation, especially if socket options had been set
2462 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2463 new implementation of bind_port() will actually raise an exception
2464 if it is passed an AF_INET/SOCK_STREAM socket with either the
2465 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2466 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2467 the socket it's been passed. This currently only applies to
2468 Windows. This option prevents any other sockets from binding to the
2469 host/port we've bound to, thus removing the possibility of the
2470 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2471 when a second SOCK_STREAM socket binds and accepts to a host/port
2472 that's already been bound by another socket. The optional preferred
2473 port parameter to bind_port() has been removed. Under no
2474 circumstances should tests be hard coding ports!
2475
2476 test_support.find_unused_port() has also been introduced, which will
2477 pass a temporary socket object to bind_port() in order to obtain an
2478 unused port. The temporary socket object is then closed and
2479 deleted, and the port is returned. This method should only be used
2480 for obtaining an unused port in order to pass to an external program
2481 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2482 a parameter to a server-oriented class that doesn't give you direct
2483 access to the underlying socket used.
2484
2485 Finally, test_support.HOST has been introduced, which should be used
2486 for the host argument of any relevant socket calls (i.e. bind and
2487 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002488
2489 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002490 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002491 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2492 test_asynchat and test_socket_ssl.
2493
Georg Brandl3ee81df2008-05-17 18:14:43 +00002494 It is now possible for multiple instances of the regression test
2495 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002701 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
2702 files are used. On all linux systems the --with-system-ffi
2703 configure option defaults to "yes".

2762-----------------
2763
Fred Drakea8ee94b2008-03-01 02:45:07 +00002764- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002765 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002766
Georg Brandlad61bc82008-02-23 15:11:18 +00002767- Issue #2067: file.__exit__() now calls subclasses' close() method.
2768
2769- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002770
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002771- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002772 issue 215555 for a discussion.
2773
Eric Smitha73fbe72008-02-23 03:09:44 +00002774- Added the future_builtins module, which contains hex() and oct().
2775 These are the PEP 3127 version of these functions, designed to be
2776 compatible with the hex() and oct() builtins from Python 3.0. They
2777 differ slightly in their output formats from the existing, unchanged
2778 Python 2.6 builtins. The expected usage of the future_builtins
2779 module is:
2780 from future_builtins import hex, oct
2781
Eric Smith7ef40bf2008-02-20 23:34:22 +00002782- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2783 exponents for exponents with absolute value < 100. Follows C99
2784 standard. This is a change on Windows, which would use 3 digits.
2785 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2786 so that any alterations it does to the resulting string will be
2787 available in stringlib/formatter.h (for float.__format__).
2788
Eric Smith5a3c1352008-02-19 13:21:56 +00002789- Implemented PEP 3101, Advanced String Formatting. This adds a new
2790 builtin format(); a format() method for str and unicode; a
2791 __format__() method to object, str, unicode, int, long, float, and
2792 datetime; the class string.Formatter; and the C API
2793 PyObject_Format().
2794
Georg Brandl3ee81df2008-05-17 18:14:43 +00002795- Fixed several potential crashes, all caused by specially crafted
2796 __del__ methods exploiting objects in temporarily inconsistent
2797 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002798
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002799- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002800 prevent a possible crash: an Abstract Base Class would try to access
2801 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002802
Georg Brandl3ee81df2008-05-17 18:14:43 +00002803- Fixed repr() and str() of complex numbers with infinity or nan as
2804 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002805
Georg Brandl3ee81df2008-05-17 18:14:43 +00002806- Clear all free lists during a gc.collect() of the highest generation
2807 in order to allow pymalloc to free more arenas. Python may give back
2808 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002809
Georg Brandl3ee81df2008-05-17 18:14:43 +00002810- Issue #2045: Fix an infinite recursion triggered when printing a
2811 subclass of collections.defaultdict, if its default_factory is set
2812 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002813
Christian Heimesf75dbef2008-02-08 00:11:31 +00002814- Fixed a minor memory leak in dictobject.c. The content of the free
2815 list was not freed on interpreter shutdown.
2816
Georg Brandl5a7eca12010-03-21 19:29:04 +00002817- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00002818 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002819
Georg Brandl3ee81df2008-05-17 18:14:43 +00002820- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2821 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002822 to compact the internal free lists of pre-allocted ints and floats.
2823
Georg Brandl3ee81df2008-05-17 18:14:43 +00002824- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2825 calls. Python expected the return type int but the fork familie
2826 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002827
Georg Brandl3ee81df2008-05-17 18:14:43 +00002828- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2829 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002830

2838 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002839
Georg Brandl3ee81df2008-05-17 18:14:43 +00002840- Patch #1473257: generator objects gain a gi_code attribute. This is
2841 the same object as the func_code attribute of the function that
2842 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002843
Georg Brandl3ee81df2008-05-17 18:14:43 +00002844- Issue #1920: "while 0" statements were completely removed by the
2845 compiler, even in the presence of an "else" clause, which is
2846 supposed to be run when the condition is false. Now the compiler
2847 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002848
Guido van Rossumeead05f2008-01-24 18:21:02 +00002849- A few crashers fixed: weakref_in_del.py (issue #1377858);
2850 loosing_dict_ref.py (issue #1303614, test67.py);
2851 borrowed_ref_[34].py (not in tracker).
2852
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002853- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002854 suppressed while an extension is loaded by calling SetErrorMode in
2855 dynload_win.c. The error is still reported properly.
2856
Georg Brandl3ee81df2008-05-17 18:14:43 +00002857- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002858 several extension methods and modules do not work without unicode
2859 support.
2860
Georg Brandl26543b12008-01-21 18:36:51 +00002861- Issue #1882: when compiling code from a string, encoding cookies in the
2862 second line of code were not always recognized correctly.
2863
Georg Brandl14404b62008-01-19 19:27:05 +00002864- Issue #1679: "0x" was taken as a valid integer literal.
2865
Georg Brandl6caad7d2008-01-26 14:19:22 +00002866- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002867 added.
2868
Christian Heimesc94e2b52008-01-14 04:13:37 +00002869- sys.float_info / PyFloat_GetInfo: The floating point information
2870 object was converted from a dict to a specialized structseq object.
2871
Georg Brandl3ee81df2008-05-17 18:14:43 +00002872- Patch #1816: Added sys.flags structseq. It exposes the status of
2873 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002874
Georg Brandl3ee81df2008-05-17 18:14:43 +00002875- Objects/structseq.c: Implemented new structseq representation. The
2876 patch makes structseqs (e.g. the return value of os.stat) more
2877 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002878
Georg Brandl3ee81df2008-05-17 18:14:43 +00002879- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00002901 and INF. float("nan"), float("inf") and float("-inf") now work on
2902 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002903
Georg Brandl3ee81df2008-05-17 18:14:43 +00002904- Compiler now generates simpler and faster code for dictionary
2905 literals. The oparg for BUILD_MAP now indicates an estimated
2906 dictionary size. There is a new opcode, STORE_MAP, for adding
2907 entries to the dictionary.

2942 function uses a generator expression when at the same time the
2943 executed code is closing a paused generator.

2950
Georg Brandl5a7eca12010-03-21 19:29:04 +00002951- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00002952 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2953 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002954
Georg Brandl3ee81df2008-05-17 18:14:43 +00002955- Issue #1686386: Tuple's tp_repr did not take into account the
2956 possibility of having a self-referential tuple, which is possible
2957 from C code. Nor did object's tp_str consider that a type's tp_str
2958 could do something that could lead to an inifinite recursion.
2959 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2960 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002961
Georg Brandl3ee81df2008-05-17 18:14:43 +00002962- Issue #1164: It was possible to trigger deadlock when using the
2963 'print' statement to write to a file since the GIL was not released
2964 as needed. Now PyObject_Print() does the right thing along with
2965 various tp_print implementations of the built-in types and those in
2966 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002967
Georg Brandl3ee81df2008-05-17 18:14:43 +00002968- Issue #1147: Exceptions were directly allowing string exceptions in

2970 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00002974
Brett Cannon1e534b52007-09-07 04:18:30 +00002975- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002976 PyObject_Call() never calling back out to Python code to trigger
2977 recursion depth updates/checks. Required the creation of a static
2978 RuntimeError instance in case normalizing an exception put the
2979 recursion check value past its limit. Fixes crashers
2980 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00002995- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002996 __*__ attributes. (Some already existed, e.g., __doc__ and
2997 __name__.)

3003 calls.
3004
Collin Winter62903052007-05-18 23:11:24 +00003005- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003006 "except E as target:". This is to provide forwards compatibility
3007 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00003014- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003015 setting a plain string, ie don't expand to single letter identifiers.
3016
Raymond Hettinger13936692007-04-11 18:40:58 +00003017- Request #1191699: Slices can now be pickled.
3018
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003019- Request #1193128: str.translate() now allows a None argument for

3021 remaining characters.
3022
Georg Brandl5cb76c12007-03-21 09:00:39 +00003023- Patch #1682205: a TypeError while unpacking an iterable is no longer

3027
Guido van Rossum143b5642007-03-23 04:58:42 +00003028- Bug #1683368: The object.__init__() and object.__new__() methods are
3029 now stricter in rejecting excess arguments. The only time when
3030 either allows excess arguments is when it is not overridden and the
3031 other one is. For backwards compatibility, when both are
3032 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003033 warning later). Also, type.__init__() insists on the same signature
3034 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003035
Georg Brandl3ee81df2008-05-17 18:14:43 +00003036- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3037 object to complex using its __complex__() method before falling back
3038 to the __float__() method. Therefore, the functions in the cmath
3039 module now can operate on objects that define a __complex__()
3040 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003041

3051 its type.

3057
Georg Brandl7b9c5552007-03-12 14:30:05 +00003058- Bug #1678647: write a newline after printing an exception in any
3059 case, even when converting the value to a string failed.
3060
Georg Brandl871f1bc2007-03-12 13:17:36 +00003061- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003062 its argument, if it exists. If not, it will work like before. This
3063 allows customizing the output of dir() in the presence of a
3064 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003072- Patch #1491866: change the complex() constructor to allow
3073 parthensized forms. This means complex(repr(x)) now works instead of
3074 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003075
Georg Brandlaa2321b2007-03-07 00:40:28 +00003076- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003077 makes the filenames the warning module prints much more sensible
3078 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003079

Georg Brandl0fca97a2007-03-05 22:28:08 +00003091- Patch #1674228: when assigning a slice (old-style), check for the
3092 sq_ass_slice instead of the sq_slice slot.
3093
Georg Brandl3ee81df2008-05-17 18:14:43 +00003094- When printing an unraisable error, don't print exceptions. before
3095 the name. This duplicates the behavior whening normally printing
3096 exceptions.

3724 -- the failure just occurred later, with a more cumbersome
3725 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004006- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4007 with RFC 3207 and forgets any knowledge obtained from the server not
4008 obtained from the TLS negotiation itself. Patch contributed by Bill
4009 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004010
Georg Brandl3ee81df2008-05-17 18:14:43 +00004011- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004012 that the SMTP.starttls() caller no longer needs to call ehlo()
4013 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004014 does not claim to support starttls. Adds the
4015 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4096 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4097 silently miscode subclasses of those types. Now, it raises a

Raymond Hettinger12e94202007-11-07 01:13:09 +00004099

Georg Brandl3ee81df2008-05-17 18:14:43 +00004114 time so that opening a database previously created with the DB_DUP
4115 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4116 opens. Specifically: dictionary assignment to a DB object will
4117 replace all values for a given key when the database allows
4118 duplicate values. DB users should use DB.put(k, v) when they want
4119 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004120

4126 characters with ASCII value less than 32. Also, it correctly quotes
4127 dots only if they occur on a single line, as opposed to the previous
4128 behavior of quoting dots if they are the second character of any
4129 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004130

4452-----
4453
Georg Brandl3ee81df2008-05-17 18:14:43 +00004454- Unified naming convention for free lists and their limits. All free
4455 lists in Object/ are named ``free_list``, the counter ``numfree``
4456 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4457 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004458
Georg Brandl3ee81df2008-05-17 18:14:43 +00004459- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4460 to ``PyTuple_SetItem``, it can be used to populate a brand new
4461 frozenset; but it does not steal a reference to the added item.

4473
Georg Brandl3ee81df2008-05-17 18:14:43 +00004474- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4475 of w# format code incorrectly truncated the length to an int, even
4476 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4477 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004478
Georg Brandl3ee81df2008-05-17 18:14:43 +00004479- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4497- Fix some leftovers from the conversion from int to Py_ssize_t
4498 (relevant to strings and sequences of more than 2**31 items).
4499
4500- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4501 outside of pystate.c and should not be necessary.
4502
Georg Brandl3ee81df2008-05-17 18:14:43 +00004503- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4504 absolute imports. In earlier versions they might have used relative
4505 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004506
Georg Brandl3ee81df2008-05-17 18:14:43 +00004507- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4508 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004509
Georg Brandl3ee81df2008-05-17 18:14:43 +00004510- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

4518 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4519 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4520 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004521

Georg Brandl3ee81df2008-05-17 18:14:43 +00004535- Removed the macfs module. It had been deprecated since Python 2.5.
4536 This lead to the deprecation of macostools.touched() as it relied
4537 solely on macfs and was a no-op under OS X.
