1096
1097- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
1098 302 conformant loader) will now work correctly in most cases (they

1292- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1293 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1294 really executed because I cannot move to such directory on win2k)

1450
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001451- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1452 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1453 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1454 ``printf`` function, whereas PyString_FromFormat has an independent
1455 implementation and uses "%zd" on all platforms for size_t values.
1456 This makes a difference on win64, where ``printf`` needs "%Id" to display
1457 64bit values.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001474 was correctly parsed but parsing of subsequent arguments failed.

Vinay Sajip35e3b032008-09-01 14:33:59 +00001476- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001477 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1478 mechanism. In the process, fix a bug where isinstance() and issubclass(),

1480 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1481 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001617What's New in Python 2.6 beta 3?
1618================================
1619
Barry Warsaw07a4a382008-08-21 01:15:08 +00001620*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001621
1622Core and Builtins
1623-----------------
1624
Guido van Rossumf8402962008-08-20 15:01:50 +00001625- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1626 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1627 extensions do not automatically benefit from the class attribute
1628 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1629 to their tp_flags field if they care. This is a backwards
1630 compatibility feature; in 3.0, all types will use the cache by
1631 default.
1632
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001633- Keyword arguments can now follow starred arguments. (``f(a, *args,
1634 keyword=23)`` is now valid syntax.)
1635
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001636- ctypes function pointers that are COM methods have a boolean True
1637 value again.
1638
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001639- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1640 by denying s# to parse objects that have a releasebuffer procedure,
1641 and introducing s*.
1642
Georg Brandl1e13ea92008-08-11 09:07:59 +00001643- Issue #3537: Fix an assertion failure when an empty but presized dict
1644 object was stored in the freelist.
1645
Mark Dickinsonb6467572008-08-04 21:30:09 +00001646- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1647 ValueError consistently across platforms.
1648
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001649- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1650 (64bit Unix, for example), unichr() would truncate its argument and return
1651 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1652
Neal Norwitze7d8be82008-07-31 17:17:14 +00001653- Apply security patches from Apple.
1654
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001655- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1656 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1657
Antoine Pitrou92f82162008-07-25 22:22:08 +00001658- Issue #1819: function calls with several named parameters are now on
1659 average 35% faster (as measured by pybench).
1660
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001661- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1662 the python debugger steps into a class statement: the free variables (local
1663 variables defined in an outer scope) would be deleted from the outer scope.
1664
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001665- Issue #2620: Overflow checking when allocating or reallocating memory
1666 was not always being done properly in some python types and extension
1667 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1668 all been updated to perform better checks and places in the code that
1669 would previously leak memory on the error path when such an allocation
1670 failed have been fixed.
1671
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001672Library
1673-------
1674
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001675- Issue #3612: Added some missing basic types in ctypes.wintypes.
1676
Benjamin Petersone977ad42008-08-20 01:42:01 +00001677- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1678 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1679
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001680- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1681 version reported by these tools does not necessarily follow the python
1682 version numbering scheme, so the module is less strict when parsing it.
1683
Nick Coghlanf70385a2008-08-18 12:42:46 +00001684- Issue #2235: Added Py3k warnings for types which will become unhashable
1685 under the stricter __hash__ inheritance rules in 3.0. Several types
1686 which did not meet the rules for hash invariants and were already
1687 unhashable in 3.0 have now been explicitly flagged as unhashable in
1688 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1689 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1690
Brett Cannon88f801d2008-08-18 00:46:22 +00001691- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1692 imported into the module but exposed as part of the module's API.
1693
Brett Cannon7b96f072008-08-18 00:41:11 +00001694- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1695
Brett Cannon46225e72008-08-18 00:36:52 +00001696- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1697
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001698- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1699
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001700- Issue #3575: Incremental decoder's decode function now takes bytearray
1701 by using 's*' instead of 't#'.
1702
Jesus Cea585ad8a2009-07-02 15:37:21 +00001703- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001704 fails unicode conversion on 2nd parameter. (windows only)
1705
Facundo Batista94f243a2008-08-17 03:38:39 +00001706- Issue 2464. urllib2 now supports a malformation in the URL received
1707 in a redirect.
1708
Brett Cannonabe423e2008-08-16 21:47:07 +00001709- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001710 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001711
Facundo Batistaeb90b782008-08-16 14:44:07 +00001712- Issue #2776: fixed small issue when handling an URL with double slash
1713 after a 302 response in the case of not going through a proxy.
1714
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001715- Issue #2676: in the email package, content-type parsing was hanging on
1716 pathological input because of quadratic or exponential behaviour of a
1717 regular expression.
1718
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001719- Issue #3476: binary buffered reading through the new "io" library is now
1720 thread-safe.
1721
Brett Cannonbf3157b2008-08-14 05:00:03 +00001722- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1723 since mimetools itself is deprecated. Because modules are cached, all
1724 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1725
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001726- Issue #3134: shutil referenced undefined WindowsError symbol.
1727
Robert Schuppenies14646332008-08-10 11:01:53 +00001728- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1729 menu entries were not deleted.
1730
Brett Cannon83e81842008-08-09 23:30:55 +00001731- Copied the implementation of reduce() to _functools.reduce() to have a
1732 version that did not raise a DeprecationWarning under -3.
1733
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001734- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1735 a MemoryError rather than silently stop the iteration.
1736
Guido van Rossum59ce9012008-08-09 14:55:34 +00001737- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1738 to _sre.compile() will now be rejected. This should not affect anybody
1739 since the re.compile() function never generates invalid re-bytecode.
1740
Skip Montanaroa032bf42008-08-08 22:52:51 +00001741- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1742 upon first access it can be automatically initialized from the csv file if
1743 it wasn't initialized during instantiation.
1744
Brett Cannon3aa2a492008-08-06 22:28:09 +00001745- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1746 the reload() built-in has been removed.
1747
Brett Cannon7e30b672008-08-04 21:52:25 +00001748- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001749 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1757 raised an AttributeError.
1758
Benjamin Peterson01a24322008-07-28 23:35:27 +00001759- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001760 asking for a specific length. This problem only affected files opened
1761 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001762
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001763- Issue #3449: Update decimal module to use most recent specification
1764 (v. 1.68) and tests (v. 2.58) from IBM.
1765
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001766- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

1774
1775- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1776 invalid arguments.
1777
1778- Issue #3302: Fix several crashes when calling locale's gettext functions
1779 with None arguments.
1780
1781- Issue #3389: Allow resolving dotted names for handlers in logging
1782 configuration files.
1783
1784- Deprecate the sunaudio module for removal in Python 3.0.
1785
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001786- Issue #3394: zipfile.writestr sets external attributes when passed a
1787 file name rather than a ZipInfo instance, so files are extracted with
1788 mode 0600 rather than 000 under Unix.
1789
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001790- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1791 argument in python 2.5, this broke code that subclassed Popen to include its
1792 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001802- Issue #2235: the C API function PyObject_HashNotImplemented and its
1803 interaction with the tp_hash slot (added in 2.6b2) are now documented
1804
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001805- Issue #643841: The language reference now provides more detailed
1806 coverage of the lookup process for special methods. The disclaimers
1807 regarding lack of coverage of new-style classes have also been
1808 removed, since the coverage is now fairly reasonable.

1817-----------------
1818
Georg Brandl3e483f62008-07-16 22:57:41 +00001819- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1820 its methods now allow for items objects that can be converted to
1821 an integer using operator.index().
1822
Mark Dickinson64b7e502008-07-16 09:40:03 +00001823- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1824 produced a ValueError instead of giving the correct float.
1825
Eric Smitha5fa5a22008-07-16 00:11:49 +00001826- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1827 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1828
Mark Dickinson7103aa42008-07-15 19:08:33 +00001829- Issue #3008: the float type has a new instance method 'float.hex'
1830 and a new class method 'float.fromhex' to convert floating-point
1831 numbers to and from hexadecimal strings, respectively.
1832
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001833- Issue #2235: __hash__ is once again inherited by default. To allow
1834 collections.Hashable to remain meaningful in the presence of the
1835 default hash implementation (object.__hash__), it is now possible
1836 to explicit block inheritance of hash by setting __hash__=None at
1837 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1838 level.
1839
Nick Coghlanb028f502008-07-13 14:52:36 +00001840- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1841 the parent module cannot be found while performing an absolute import.
1842 This means that an incorrectly defined __package__ attribute will
1843 now only prevent relative imports in that module rather than causing
1844 all imports from that module to fail.
1845
Nick Coghlan14ff9942008-07-08 14:21:42 +00001846- Issue #2517: Allow unicode messages in Exceptions again by correctly
1847 bypassing the instance dictionary when looking up __unicode__ on
1848 new-style classes.
1849
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001850- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1851 set to a custom object whose write() method happens to install
1852 another file in sys.stdout.

1856 another thread's dictionary.
1857
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001858- Issue #3004: Minor change to slice.indices(): the start and stop
1859 arguments are now treated identically, making the behaviour easier
1860 to describe and understand. For example, slice(None, -10,
1861 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1862 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1863 10, -1).
1864
Georg Brandl278fc502008-07-19 12:46:12 +00001865- Issue #3219: Calling a function with repeated keyword arguments,

Georg Brandl5cc774e2008-06-11 20:28:06 +00002317 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002318
2319 This is controlled by the configure argument ``--with-universal-archs``:
2320
2321 - ``--with-universal-archs=all``: install 4-way universal
2322
2323 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2324
2325 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2326

Georg Brandl3ee81df2008-05-17 18:14:43 +00002379- Issue #1631171: Re-implement the 'warnings' module in C (the
2380 original Python code has been kept as backup). This will allow for
2381 using the 'warning's machinery in such places as the parser where
2382 use of pure Python code is not possible. Both the ``showarning()``
2383 and ``formatwarning()`` gain an optional 'line' argument which is
2384 not called by default for backwards-compatibility reasons. Setting
2385 ``warnings.showwarning()`` to an implementation that lacks support
2386 for the ``line`` argument will raise a DeprecationWarning.

2434 file.close() is called while an object is in use by another thread
2435 an IOError exception will be raised and the file will not be closed.

2439 Modules/_ctypes/libffi/configure.ac.
2440
Georg Brandl3ee81df2008-05-17 18:14:43 +00002441- Issue #2385: distutils.core.run_script() makes __file__ available,
2442 so the controlled environment will more closely mirror the typical
2443 script environment. This supports setup.py scripts that refer to
2444 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002449- Issue #2550: The approach used by client/server code for obtaining
2450 ports to listen on in network-oriented tests has been refined in an
2451 effort to facilitate running multiple instances of the entire
2452 regression test suite in parallel without issue.
2453 test_support.bind_port() has been fixed such that it will always
2454 return a unique port -- which wasn't always the case with the
2455 previous implementation, especially if socket options had been set
2456 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2457 new implementation of bind_port() will actually raise an exception
2458 if it is passed an AF_INET/SOCK_STREAM socket with either the
2459 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2460 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2461 the socket it's been passed. This currently only applies to
2462 Windows. This option prevents any other sockets from binding to the
2463 host/port we've bound to, thus removing the possibility of the
2464 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2465 when a second SOCK_STREAM socket binds and accepts to a host/port
2466 that's already been bound by another socket. The optional preferred
2467 port parameter to bind_port() has been removed. Under no
2468 circumstances should tests be hard coding ports!
2469
2470 test_support.find_unused_port() has also been introduced, which will
2471 pass a temporary socket object to bind_port() in order to obtain an
2472 unused port. The temporary socket object is then closed and
2473 deleted, and the port is returned. This method should only be used
2474 for obtaining an unused port in order to pass to an external program
2475 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2476 a parameter to a server-oriented class that doesn't give you direct
2477 access to the underlying socket used.
2478
2479 Finally, test_support.HOST has been introduced, which should be used
2480 for the host argument of any relevant socket calls (i.e. bind and
2481 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002482
2483 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002484 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002485 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2486 test_asynchat and test_socket_ssl.
2487
Georg Brandl3ee81df2008-05-17 18:14:43 +00002488 It is now possible for multiple instances of the regression test
2489 suite to run in parallel without issue.

Thomas Heller78b8f442008-03-05 14:53:39 +00002693- The bundled libffi copy is now in sync with the recently released
2694 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002695 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
2696 files are used. On all linux systems the --with-system-ffi
2697 configure option defaults to "yes".

2757
Fred Drakea8ee94b2008-03-01 02:45:07 +00002758- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002759 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00002761- Issue #2067: file.__exit__() now calls subclasses' close() method.
2762
2763- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002764
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002765- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002766 issue 215555 for a discussion.
2767
Eric Smitha73fbe72008-02-23 03:09:44 +00002768- Added the future_builtins module, which contains hex() and oct().
2769 These are the PEP 3127 version of these functions, designed to be
2770 compatible with the hex() and oct() builtins from Python 3.0. They
2771 differ slightly in their output formats from the existing, unchanged
2772 Python 2.6 builtins. The expected usage of the future_builtins
2773 module is:
2774 from future_builtins import hex, oct
2775
Eric Smith7ef40bf2008-02-20 23:34:22 +00002776- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2777 exponents for exponents with absolute value < 100. Follows C99
2778 standard. This is a change on Windows, which would use 3 digits.
2779 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2780 so that any alterations it does to the resulting string will be
2781 available in stringlib/formatter.h (for float.__format__).
2782
Eric Smith5a3c1352008-02-19 13:21:56 +00002783- Implemented PEP 3101, Advanced String Formatting. This adds a new
2784 builtin format(); a format() method for str and unicode; a
2785 __format__() method to object, str, unicode, int, long, float, and
2786 datetime; the class string.Formatter; and the C API
2787 PyObject_Format().
2788
Georg Brandl3ee81df2008-05-17 18:14:43 +00002789- Fixed several potential crashes, all caused by specially crafted
2790 __del__ methods exploiting objects in temporarily inconsistent
2791 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002792
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002793- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002794 prevent a possible crash: an Abstract Base Class would try to access
2795 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002796
Georg Brandl3ee81df2008-05-17 18:14:43 +00002797- Fixed repr() and str() of complex numbers with infinity or nan as
2798 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002799
Georg Brandl3ee81df2008-05-17 18:14:43 +00002800- Clear all free lists during a gc.collect() of the highest generation
2801 in order to allow pymalloc to free more arenas. Python may give back
2802 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002803
Georg Brandl3ee81df2008-05-17 18:14:43 +00002804- Issue #2045: Fix an infinite recursion triggered when printing a
2805 subclass of collections.defaultdict, if its default_factory is set
2806 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002807
Christian Heimesf75dbef2008-02-08 00:11:31 +00002808- Fixed a minor memory leak in dictobject.c. The content of the free
2809 list was not freed on interpreter shutdown.
2810
Georg Brandl5a7eca12010-03-21 19:29:04 +00002811- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00002812 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002813
Georg Brandl3ee81df2008-05-17 18:14:43 +00002814- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2815 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002816 to compact the internal free lists of pre-allocted ints and floats.
2817
Georg Brandl3ee81df2008-05-17 18:14:43 +00002818- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2819 calls. Python expected the return type int but the fork familie
2820 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002821
Georg Brandl3ee81df2008-05-17 18:14:43 +00002822- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2823 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002824
Georg Brandl3ee81df2008-05-17 18:14:43 +00002825- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2826 with the collections.Sequence API.

2832 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002833
Georg Brandl3ee81df2008-05-17 18:14:43 +00002834- Patch #1473257: generator objects gain a gi_code attribute. This is
2835 the same object as the func_code attribute of the function that
2836 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002837
Georg Brandl3ee81df2008-05-17 18:14:43 +00002838- Issue #1920: "while 0" statements were completely removed by the
2839 compiler, even in the presence of an "else" clause, which is
2840 supposed to be run when the condition is false. Now the compiler
2841 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002842
Guido van Rossumeead05f2008-01-24 18:21:02 +00002843- A few crashers fixed: weakref_in_del.py (issue #1377858);
2844 loosing_dict_ref.py (issue #1303614, test67.py);
2845 borrowed_ref_[34].py (not in tracker).
2846
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002847- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002848 suppressed while an extension is loaded by calling SetErrorMode in
2849 dynload_win.c. The error is still reported properly.
2850
Georg Brandl3ee81df2008-05-17 18:14:43 +00002851- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002852 several extension methods and modules do not work without unicode
2853 support.
2854
Georg Brandl26543b12008-01-21 18:36:51 +00002855- Issue #1882: when compiling code from a string, encoding cookies in the
2856 second line of code were not always recognized correctly.
2857
Georg Brandl14404b62008-01-19 19:27:05 +00002858- Issue #1679: "0x" was taken as a valid integer literal.
2859
Georg Brandl6caad7d2008-01-26 14:19:22 +00002860- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002861 added.
2862
Christian Heimesc94e2b52008-01-14 04:13:37 +00002863- sys.float_info / PyFloat_GetInfo: The floating point information
2864 object was converted from a dict to a specialized structseq object.
2865
Georg Brandl3ee81df2008-05-17 18:14:43 +00002866- Patch #1816: Added sys.flags structseq. It exposes the status of
2867 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002868
Georg Brandl3ee81df2008-05-17 18:14:43 +00002869- Objects/structseq.c: Implemented new structseq representation. The
2870 patch makes structseqs (e.g. the return value of os.stat) more
2871 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002872
Georg Brandl3ee81df2008-05-17 18:14:43 +00002873- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00002895 and INF. float("nan"), float("inf") and float("-inf") now work on
2896 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002897
Georg Brandl3ee81df2008-05-17 18:14:43 +00002898- Compiler now generates simpler and faster code for dictionary
2899 literals. The oparg for BUILD_MAP now indicates an estimated
2900 dictionary size. There is a new opcode, STORE_MAP, for adding
2901 entries to the dictionary.

2944
Georg Brandl5a7eca12010-03-21 19:29:04 +00002945- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00002946 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2947 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002948
Georg Brandl3ee81df2008-05-17 18:14:43 +00002949- Issue #1686386: Tuple's tp_repr did not take into account the
2950 possibility of having a self-referential tuple, which is possible
2951 from C code. Nor did object's tp_str consider that a type's tp_str
2952 could do something that could lead to an inifinite recursion.
2953 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2954 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002955
Georg Brandl3ee81df2008-05-17 18:14:43 +00002956- Issue #1164: It was possible to trigger deadlock when using the
2957 'print' statement to write to a file since the GIL was not released
2958 as needed. Now PyObject_Print() does the right thing along with
2959 various tp_print implementations of the built-in types and those in
2960 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002961
Georg Brandl3ee81df2008-05-17 18:14:43 +00002962- Issue #1147: Exceptions were directly allowing string exceptions in
2963 their throw() method even though string exceptions no longer
2964 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002965
Georg Brandl3ee81df2008-05-17 18:14:43 +00002966- Issue #1096: Prevent a segfault from getting the repr of a very
2967 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002968
Brett Cannon1e534b52007-09-07 04:18:30 +00002969- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002970 PyObject_Call() never calling back out to Python code to trigger
2971 recursion depth updates/checks. Required the creation of a static
2972 RuntimeError instance in case normalizing an exception put the
2973 recursion check value past its limit. Fixes crashers
2974 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002975

Neal Norwitz0ac60192007-05-27 04:08:54 +00002989- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002990 __*__ attributes. (Some already existed, e.g., __doc__ and
2991 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002992
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002993- Add -3 option to the interpreter to warn about features that are
2994 deprecated and will be changed/removed in Python 3.0.
2995
Georg Brandl2134e752007-05-21 20:34:16 +00002996- Patch #1686487: you can now pass any mapping after '**' in function
2997 calls.
2998
Collin Winter62903052007-05-18 23:11:24 +00002999- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003000 "except E as target:". This is to provide forwards compatibility
3001 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003002
Brett Cannon229cee22007-05-05 01:34:02 +00003003- Deprecate BaseException.message as per PEP 352.
3004
Georg Brandl3ee81df2008-05-17 18:14:43 +00003005- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003006 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003007
Vinay Sajip8549ce32007-05-06 17:53:37 +00003008- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003009 setting a plain string, ie don't expand to single letter identifiers.
3010
Raymond Hettinger13936692007-04-11 18:40:58 +00003011- Request #1191699: Slices can now be pickled.
3012
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003013- Request #1193128: str.translate() now allows a None argument for
3014 translations that only remove characters without re-mapping the
3015 remaining characters.
3016
Georg Brandl5cb76c12007-03-21 09:00:39 +00003017- Patch #1682205: a TypeError while unpacking an iterable is no longer
3018 masked by a generic one with the message "unpack non-sequence".
3019
Neal Norwitzaa754b72007-03-21 06:39:48 +00003020- Remove unused file Python/fmod.c.
3021
Guido van Rossum143b5642007-03-23 04:58:42 +00003022- Bug #1683368: The object.__init__() and object.__new__() methods are
3023 now stricter in rejecting excess arguments. The only time when
3024 either allows excess arguments is when it is not overridden and the
3025 other one is. For backwards compatibility, when both are
3026 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003027 warning later). Also, type.__init__() insists on the same signature
3028 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003029
Georg Brandl3ee81df2008-05-17 18:14:43 +00003030- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3031 object to complex using its __complex__() method before falling back
3032 to the __float__() method. Therefore, the functions in the cmath
3033 module now can operate on objects that define a __complex__()
3034 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003035
Georg Brandl3ee81df2008-05-17 18:14:43 +00003036- Patch #1623563: allow __class__ assignment for classes with
3037 __slots__. The old and the new class are still required to have the
3038 same slot names.

3044 ``object.__reduce_ex__()`` is called with an object that is faking
3045 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003046
Georg Brandl3ee81df2008-05-17 18:14:43 +00003047- Patch #1680015: Don't modify __slots__ tuple if it contains an

3051
Georg Brandl7b9c5552007-03-12 14:30:05 +00003052- Bug #1678647: write a newline after printing an exception in any
3053 case, even when converting the value to a string failed.
3054
Georg Brandl871f1bc2007-03-12 13:17:36 +00003055- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003056 its argument, if it exists. If not, it will work like before. This
3057 allows customizing the output of dir() in the presence of a
3058 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003066- Patch #1491866: change the complex() constructor to allow
3067 parthensized forms. This means complex(repr(x)) now works instead of
3068 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003069
Georg Brandlaa2321b2007-03-07 00:40:28 +00003070- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003071 makes the filenames the warning module prints much more sensible
3072 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003073
Georg Brandl49aafc92007-03-07 00:34:46 +00003074- Variant of patch #697613: don't exit the interpreter on a SystemExit
3075 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003076 variable is given, but break into the interactive interpreter just
3077 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003085- Patch #1674228: when assigning a slice (old-style), check for the
3086 sq_ass_slice instead of the sq_slice slot.
3087
Georg Brandl3ee81df2008-05-17 18:14:43 +00003088- When printing an unraisable error, don't print exceptions. before
3089 the name. This duplicates the behavior whening normally printing
3090 exceptions.

3719 exception.

3933
Georg Brandl3ee81df2008-05-17 18:14:43 +00003934- Fix turtle so that time.sleep is imported for the entire library.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004000- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4001 with RFC 3207 and forgets any knowledge obtained from the server not
4002 obtained from the TLS negotiation itself. Patch contributed by Bill
4003 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004004
Georg Brandl3ee81df2008-05-17 18:14:43 +00004005- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004006 that the SMTP.starttls() caller no longer needs to call ehlo()
4007 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004008 does not claim to support starttls. Adds the
4009 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4010 Fenner.

4090 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4091 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00004108 time so that opening a database previously created with the DB_DUP
4109 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4110 opens. Specifically: dictionary assignment to a DB object will
4111 replace all values for a given key when the database allows
4112 duplicate values. DB users should use DB.put(k, v) when they want
4113 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004114

4120 characters with ASCII value less than 32. Also, it correctly quotes
4121 dots only if they occur on a single line, as opposed to the previous
4122 behavior of quoting dots if they are the second character of any
4123 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004124

4446-----
4447
Georg Brandl3ee81df2008-05-17 18:14:43 +00004448- Unified naming convention for free lists and their limits. All free
4449 lists in Object/ are named ``free_list``, the counter ``numfree``
4450 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4451 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004452
Georg Brandl3ee81df2008-05-17 18:14:43 +00004453- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4454 to ``PyTuple_SetItem``, it can be used to populate a brand new
4455 frozenset; but it does not steal a reference to the added item.

4464
4465- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4466 ``PyFloat_GetInfo()`` to the float API.
4467
Georg Brandl3ee81df2008-05-17 18:14:43 +00004468- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4469 of w# format code incorrectly truncated the length to an int, even
4470 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4471 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004472
Georg Brandl3ee81df2008-05-17 18:14:43 +00004473- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4491- Fix some leftovers from the conversion from int to Py_ssize_t
4492 (relevant to strings and sequences of more than 2**31 items).
4493
4494- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4495 outside of pystate.c and should not be necessary.
4496
Georg Brandl3ee81df2008-05-17 18:14:43 +00004497- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4498 absolute imports. In earlier versions they might have used relative
4499 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004500
Georg Brandl3ee81df2008-05-17 18:14:43 +00004501- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4502 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004503
Georg Brandl3ee81df2008-05-17 18:14:43 +00004504- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

4514 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004515

Georg Brandl3ee81df2008-05-17 18:14:43 +00004529- Removed the macfs module. It had been deprecated since Python 2.5.
4530 This lead to the deprecation of macostools.touched() as it relied
4531 solely on macfs and was a no-op under OS X.
