1287==========================
1288
1289*Release date: 04-Dec-2008*
1290
1291Core and Builtins
1292-----------------
1293
1294- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1295 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1296 instead of throwing a MemoryError.
1297
1298- Issue #4367: Python would segfault during compiling when the unicodedata
1299 module couldn't be imported and \N escapes were present.
1300
1301- Issue #4348: Some bytearray methods returned that didn't cause any change to
1302 the bytearray, returned the same bytearray instead of a copy.
1303
1304- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1305
1306- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1307
1308- Issue #4048: The parser module now correctly validates relative imports.
1309
1310- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1311 exec statement.

1313- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1314 method does not return iterators for the 4th and 5th items.
1315
1316- Issue #4209: Enabling unicode_literals and the print_function in the same
1317 __future__ import didn't work.
1318
1319- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1320 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1321 really executed because I cannot move to such directory on win2k)
1322
1323- Issue #4069: When set.remove(element) is used with a set element, the element
1324 is temporarily replaced with an equivalent frozenset. But the eventual
1325 KeyError would always report the empty frozenset([]) as the missing key. Now
1326 it correctly refers to the initial element.
1327
1328- Fixed C99 style comments in several files. Python is now C89 compatible
1329 again.

1477
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001478- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1479 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1480 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1481 ``printf`` function, whereas PyString_FromFormat has an independent
1482 implementation and uses "%zd" on all platforms for size_t values.
1483 This makes a difference on win64, where ``printf`` needs "%Id" to display
1484 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00001504 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1505 mechanism. In the process, fix a bug where isinstance() and issubclass(),

1507 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1508 type object.

1601-----------------
1602
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001603- Issue #2975: When compiling several extension modules with Visual Studio 2008
1604 from the same python interpreter, some environment variables would grow
1605 without limit.
1606
Benjamin Peterson37346b22008-08-23 20:27:43 +00001607- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
1608 exploitation of poor argument checking.
1609
Gerhard Häringef2276b2008-09-12 13:54:06 +00001610- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

1613 remaining ones have "pysqlite_" prefix.
1614
Gerhard Häringe6872eb2008-09-12 22:33:22 +00001615- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

1623 wrapper for warnings.catch_warnings() that makes it easier to check
1624 that expected warning messages are being reported.
1625
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00001626- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001644What's New in Python 2.6 beta 3?
1645================================
1646
Barry Warsaw07a4a382008-08-21 01:15:08 +00001647*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001648
1649Core and Builtins
1650-----------------
1651
Guido van Rossumf8402962008-08-20 15:01:50 +00001652- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1653 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1654 extensions do not automatically benefit from the class attribute
1655 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1656 to their tp_flags field if they care. This is a backwards
1657 compatibility feature; in 3.0, all types will use the cache by
1658 default.
1659
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001660- Keyword arguments can now follow starred arguments. (``f(a, *args,
1661 keyword=23)`` is now valid syntax.)
1662
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001663- ctypes function pointers that are COM methods have a boolean True
1664 value again.
1665
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001666- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1667 by denying s# to parse objects that have a releasebuffer procedure,
1668 and introducing s*.
1669
Georg Brandl1e13ea92008-08-11 09:07:59 +00001670- Issue #3537: Fix an assertion failure when an empty but presized dict
1671 object was stored in the freelist.
1672
Mark Dickinsonb6467572008-08-04 21:30:09 +00001673- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1674 ValueError consistently across platforms.
1675
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001676- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1677 (64bit Unix, for example), unichr() would truncate its argument and return
1678 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1679
Neal Norwitze7d8be82008-07-31 17:17:14 +00001680- Apply security patches from Apple.
1681
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001682- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1683 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1684
Antoine Pitrou92f82162008-07-25 22:22:08 +00001685- Issue #1819: function calls with several named parameters are now on
1686 average 35% faster (as measured by pybench).
1687
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001688- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1689 the python debugger steps into a class statement: the free variables (local
1690 variables defined in an outer scope) would be deleted from the outer scope.
1691
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001692- Issue #2620: Overflow checking when allocating or reallocating memory
1693 was not always being done properly in some python types and extension
1694 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1695 all been updated to perform better checks and places in the code that
1696 would previously leak memory on the error path when such an allocation
1697 failed have been fixed.
1698
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001699Library
1700-------
1701
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001702- Issue #3612: Added some missing basic types in ctypes.wintypes.
1703
Benjamin Petersone977ad42008-08-20 01:42:01 +00001704- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1705 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1706
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001707- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1708 version reported by these tools does not necessarily follow the python
1709 version numbering scheme, so the module is less strict when parsing it.
1710
Nick Coghlanf70385a2008-08-18 12:42:46 +00001711- Issue #2235: Added Py3k warnings for types which will become unhashable
1712 under the stricter __hash__ inheritance rules in 3.0. Several types
1713 which did not meet the rules for hash invariants and were already
1714 unhashable in 3.0 have now been explicitly flagged as unhashable in
1715 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1716 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1717
Brett Cannon88f801d2008-08-18 00:46:22 +00001718- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1719 imported into the module but exposed as part of the module's API.
1720
Brett Cannon7b96f072008-08-18 00:41:11 +00001721- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1722
Brett Cannon46225e72008-08-18 00:36:52 +00001723- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001725- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1726
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001727- Issue #3575: Incremental decoder's decode function now takes bytearray
1728 by using 's*' instead of 't#'.
1729
Jesus Cea585ad8a2009-07-02 15:37:21 +00001730- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001731 fails unicode conversion on 2nd parameter. (windows only)
1732
Facundo Batista94f243a2008-08-17 03:38:39 +00001733- Issue 2464. urllib2 now supports a malformation in the URL received
1734 in a redirect.
1735
Brett Cannonabe423e2008-08-16 21:47:07 +00001736- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001737 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001738
Facundo Batistaeb90b782008-08-16 14:44:07 +00001739- Issue #2776: fixed small issue when handling an URL with double slash
1740 after a 302 response in the case of not going through a proxy.
1741
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001742- Issue #2676: in the email package, content-type parsing was hanging on
1743 pathological input because of quadratic or exponential behaviour of a
1744 regular expression.
1745
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001746- Issue #3476: binary buffered reading through the new "io" library is now
1747 thread-safe.
1748
Brett Cannonbf3157b2008-08-14 05:00:03 +00001749- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1750 since mimetools itself is deprecated. Because modules are cached, all
1751 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1752
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001753- Issue #3134: shutil referenced undefined WindowsError symbol.
1754
Robert Schuppenies14646332008-08-10 11:01:53 +00001755- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1756 menu entries were not deleted.
1757
Brett Cannon83e81842008-08-09 23:30:55 +00001758- Copied the implementation of reduce() to _functools.reduce() to have a
1759 version that did not raise a DeprecationWarning under -3.
1760
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001761- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1762 a MemoryError rather than silently stop the iteration.
1763
Guido van Rossum59ce9012008-08-09 14:55:34 +00001764- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1765 to _sre.compile() will now be rejected. This should not affect anybody
1766 since the re.compile() function never generates invalid re-bytecode.
1767
Skip Montanaroa032bf42008-08-08 22:52:51 +00001768- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1769 upon first access it can be automatically initialized from the csv file if
1770 it wasn't initialized during instantiation.
1771
Brett Cannon3aa2a492008-08-06 22:28:09 +00001772- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1773 the reload() built-in has been removed.
1774
Brett Cannon7e30b672008-08-04 21:52:25 +00001775- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001776 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1780 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1781 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.

1784 raised an AttributeError.
1785
Benjamin Peterson01a24322008-07-28 23:35:27 +00001786- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001787 asking for a specific length. This problem only affected files opened
1788 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001789
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001790- Issue #3449: Update decimal module to use most recent specification
1791 (v. 1.68) and tests (v. 2.58) from IBM.
1792

1801
1802- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1803 invalid arguments.
1804
1805- Issue #3302: Fix several crashes when calling locale's gettext functions

1812
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001813- Issue #3394: zipfile.writestr sets external attributes when passed a
1814 file name rather than a ZipInfo instance, so files are extracted with
1815 mode 0600 rather than 000 under Unix.
1816
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001817- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1818 argument in python 2.5, this broke code that subclassed Popen to include its
1819 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1827-------------
1828
Nick Coghlan6e8fef02008-08-18 13:14:22 +00001829- Issue #2235: the C API function PyObject_HashNotImplemented and its
1830 interaction with the tp_hash slot (added in 2.6b2) are now documented
1831
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001832- Issue #643841: The language reference now provides more detailed
1833 coverage of the lookup process for special methods. The disclaimers
1834 regarding lack of coverage of new-style classes have also been
1835 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001838What's New in Python 2.6 beta 2?
1839================================
1840
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001841*Release date: 17-Jul-2008*
1842
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001843Core and Builtins
1844-----------------
1845
Georg Brandl3e483f62008-07-16 22:57:41 +00001846- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1847 its methods now allow for items objects that can be converted to
1848 an integer using operator.index().
1849
Mark Dickinson64b7e502008-07-16 09:40:03 +00001850- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1851 produced a ValueError instead of giving the correct float.
1852
Eric Smitha5fa5a22008-07-16 00:11:49 +00001853- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1854 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1855
Mark Dickinson7103aa42008-07-15 19:08:33 +00001856- Issue #3008: the float type has a new instance method 'float.hex'
1857 and a new class method 'float.fromhex' to convert floating-point
1858 numbers to and from hexadecimal strings, respectively.
1859
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001860- Issue #2235: __hash__ is once again inherited by default. To allow
1861 collections.Hashable to remain meaningful in the presence of the
1862 default hash implementation (object.__hash__), it is now possible
1863 to explicit block inheritance of hash by setting __hash__=None at
1864 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1865 level.
1866
Nick Coghlanb028f502008-07-13 14:52:36 +00001867- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1868 the parent module cannot be found while performing an absolute import.
1869 This means that an incorrectly defined __package__ attribute will
1870 now only prevent relative imports in that module rather than causing
1871 all imports from that module to fail.
1872
Nick Coghlan14ff9942008-07-08 14:21:42 +00001873- Issue #2517: Allow unicode messages in Exceptions again by correctly
1874 bypassing the instance dictionary when looking up __unicode__ on
1875 new-style classes.
1876
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001877- Issue #3242: Fix a crash inside the print statement, if sys.stdout is

1889 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1890 10, -1).

Georg Brandl5cc774e2008-06-11 20:28:06 +00002344 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002345
2346 This is controlled by the configure argument ``--with-universal-archs``:

Georg Brandl3ee81df2008-05-17 18:14:43 +00002406- Issue #1631171: Re-implement the 'warnings' module in C (the
2407 original Python code has been kept as backup). This will allow for
2408 using the 'warning's machinery in such places as the parser where
2409 use of pure Python code is not possible. Both the ``showarning()``
2410 and ``formatwarning()`` gain an optional 'line' argument which is
2411 not called by default for backwards-compatibility reasons. Setting
2412 ``warnings.showwarning()`` to an implementation that lacks support
2413 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002476- Issue #2550: The approach used by client/server code for obtaining
2477 ports to listen on in network-oriented tests has been refined in an
2478 effort to facilitate running multiple instances of the entire
2479 regression test suite in parallel without issue.
2480 test_support.bind_port() has been fixed such that it will always
2481 return a unique port -- which wasn't always the case with the
2482 previous implementation, especially if socket options had been set
2483 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2484 new implementation of bind_port() will actually raise an exception
2485 if it is passed an AF_INET/SOCK_STREAM socket with either the
2486 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2487 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2488 the socket it's been passed. This currently only applies to
2489 Windows. This option prevents any other sockets from binding to the
2490 host/port we've bound to, thus removing the possibility of the
2491 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2492 when a second SOCK_STREAM socket binds and accepts to a host/port
2493 that's already been bound by another socket. The optional preferred
2494 port parameter to bind_port() has been removed. Under no
2495 circumstances should tests be hard coding ports!
2496
2497 test_support.find_unused_port() has also been introduced, which will
2498 pass a temporary socket object to bind_port() in order to obtain an
2499 unused port. The temporary socket object is then closed and
2500 deleted, and the port is returned. This method should only be used
2501 for obtaining an unused port in order to pass to an external program
2502 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2503 a parameter to a server-oriented class that doesn't give you direct
2504 access to the underlying socket used.
2505
2506 Finally, test_support.HOST has been introduced, which should be used
2507 for the host argument of any relevant socket calls (i.e. bind and
2508 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002509
2510 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002511 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002512 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2513 test_asynchat and test_socket_ssl.
2514
Georg Brandl3ee81df2008-05-17 18:14:43 +00002515 It is now possible for multiple instances of the regression test
2516 suite to run in parallel without issue.

Facundo Batistac54aec12008-03-08 16:50:27 +00002699- Issue #1106316: pdb.post_mortem()'s parameter, "traceback", is now
Georg Brandl3ee81df2008-05-17 18:14:43 +00002700 optional: it defaults to the traceback of the exception that is
2701 currently being handled (is mandatory to be in the middle of an
2702 exception, otherwise it raises ValueError).
Facundo Batistac54aec12008-03-08 16:50:27 +00002703
Jeffrey Yasskine75f59a2008-03-07 06:22:15 +00002704- Issue #1193577: A .shutdown() method has been added to SocketServers

Thomas Hellerf3c05592008-03-05 15:34:29 +00002717- Issue #1872: The struct module typecode for _Bool has been changed
2718 from 't' to '?'.
2719
Thomas Heller78b8f442008-03-05 14:53:39 +00002720- The bundled libffi copy is now in sync with the recently released
2721 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002722 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
2723 files are used. On all linux systems the --with-system-ffi
2724 configure option defaults to "yes".

2783-----------------
2784
Fred Drakea8ee94b2008-03-01 02:45:07 +00002785- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002786 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002787
Georg Brandlad61bc82008-02-23 15:11:18 +00002788- Issue #2067: file.__exit__() now calls subclasses' close() method.
2789
2790- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002791
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002792- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002793 issue 215555 for a discussion.
2794
Eric Smitha73fbe72008-02-23 03:09:44 +00002795- Added the future_builtins module, which contains hex() and oct().
2796 These are the PEP 3127 version of these functions, designed to be
2797 compatible with the hex() and oct() builtins from Python 3.0. They
2798 differ slightly in their output formats from the existing, unchanged
2799 Python 2.6 builtins. The expected usage of the future_builtins
2800 module is:
2801 from future_builtins import hex, oct
2802
Eric Smith7ef40bf2008-02-20 23:34:22 +00002803- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2804 exponents for exponents with absolute value < 100. Follows C99
2805 standard. This is a change on Windows, which would use 3 digits.
2806 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2807 so that any alterations it does to the resulting string will be
2808 available in stringlib/formatter.h (for float.__format__).
2809
Eric Smith5a3c1352008-02-19 13:21:56 +00002810- Implemented PEP 3101, Advanced String Formatting. This adds a new
2811 builtin format(); a format() method for str and unicode; a
2812 __format__() method to object, str, unicode, int, long, float, and
2813 datetime; the class string.Formatter; and the C API
2814 PyObject_Format().
2815
Georg Brandl3ee81df2008-05-17 18:14:43 +00002816- Fixed several potential crashes, all caused by specially crafted
2817 __del__ methods exploiting objects in temporarily inconsistent
2818 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002819
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002820- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002821 prevent a possible crash: an Abstract Base Class would try to access
2822 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002823
Georg Brandl3ee81df2008-05-17 18:14:43 +00002824- Fixed repr() and str() of complex numbers with infinity or nan as
2825 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002826
Georg Brandl3ee81df2008-05-17 18:14:43 +00002827- Clear all free lists during a gc.collect() of the highest generation
2828 in order to allow pymalloc to free more arenas. Python may give back
2829 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002830
Georg Brandl3ee81df2008-05-17 18:14:43 +00002831- Issue #2045: Fix an infinite recursion triggered when printing a
2832 subclass of collections.defaultdict, if its default_factory is set
2833 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002834
Christian Heimesf75dbef2008-02-08 00:11:31 +00002835- Fixed a minor memory leak in dictobject.c. The content of the free
2836 list was not freed on interpreter shutdown.
2837
Georg Brandl5a7eca12010-03-21 19:29:04 +00002838- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00002839 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002840
Georg Brandl3ee81df2008-05-17 18:14:43 +00002841- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2842 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002843 to compact the internal free lists of pre-allocted ints and floats.
2844
Georg Brandl3ee81df2008-05-17 18:14:43 +00002845- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2846 calls. Python expected the return type int but the fork familie
2847 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002848
Georg Brandl3ee81df2008-05-17 18:14:43 +00002849- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2850 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002851
Georg Brandl3ee81df2008-05-17 18:14:43 +00002852- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2853 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002854
Georg Brandl3ee81df2008-05-17 18:14:43 +00002855- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2856 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00002858- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2859 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002860
Georg Brandl3ee81df2008-05-17 18:14:43 +00002861- Patch #1473257: generator objects gain a gi_code attribute. This is
2862 the same object as the func_code attribute of the function that
2863 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002864
Georg Brandl3ee81df2008-05-17 18:14:43 +00002865- Issue #1920: "while 0" statements were completely removed by the
2866 compiler, even in the presence of an "else" clause, which is
2867 supposed to be run when the condition is false. Now the compiler
2868 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002869
Guido van Rossumeead05f2008-01-24 18:21:02 +00002870- A few crashers fixed: weakref_in_del.py (issue #1377858);
2871 loosing_dict_ref.py (issue #1303614, test67.py);
2872 borrowed_ref_[34].py (not in tracker).
2873
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002874- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002875 suppressed while an extension is loaded by calling SetErrorMode in
2876 dynload_win.c. The error is still reported properly.
2877
Georg Brandl3ee81df2008-05-17 18:14:43 +00002878- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002879 several extension methods and modules do not work without unicode
2880 support.
2881
Georg Brandl26543b12008-01-21 18:36:51 +00002882- Issue #1882: when compiling code from a string, encoding cookies in the
2883 second line of code were not always recognized correctly.
2884
Georg Brandl14404b62008-01-19 19:27:05 +00002885- Issue #1679: "0x" was taken as a valid integer literal.
2886
Georg Brandl6caad7d2008-01-26 14:19:22 +00002887- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002888 added.
2889
Christian Heimesc94e2b52008-01-14 04:13:37 +00002890- sys.float_info / PyFloat_GetInfo: The floating point information
2891 object was converted from a dict to a specialized structseq object.
2892
Georg Brandl3ee81df2008-05-17 18:14:43 +00002893- Patch #1816: Added sys.flags structseq. It exposes the status of
2894 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002895
Georg Brandl3ee81df2008-05-17 18:14:43 +00002896- Objects/structseq.c: Implemented new structseq representation. The
2897 patch makes structseqs (e.g. the return value of os.stat) more
2898 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002899
Georg Brandl3ee81df2008-05-17 18:14:43 +00002900- Patch #1700288: added a type attribute cache that caches method

2909 envvar and sys.dont_write_bytecode attribute. All these can be set
2910 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002911
Georg Brandl3ee81df2008-05-17 18:14:43 +00002912- Improve some exception messages when Windows fails to load an
2913 extension module. Now we get for example '%1 is not a valid Win32
2914 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002915

2919 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002920
Christian Heimes0a8143f2007-12-18 23:22:54 +00002921- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002922 and INF. float("nan"), float("inf") and float("-inf") now work on
2923 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002924
Georg Brandl3ee81df2008-05-17 18:14:43 +00002925- Compiler now generates simpler and faster code for dictionary
2926 literals. The oparg for BUILD_MAP now indicates an estimated
2927 dictionary size. There is a new opcode, STORE_MAP, for adding
2928 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002957- Patch #1739468: Directories and zipfiles containing a __main__.py
2958 file can now be directly executed by passing their name to the
2959 interpreter. The directory/zipfile is automatically inserted as the
2960 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002962- Issue #1265: Fix a problem with sys.settrace, if the tracing
2963 function uses a generator expression when at the same time the
2964 executed code is closing a paused generator.

2971
Georg Brandl5a7eca12010-03-21 19:29:04 +00002972- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00002973 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2974 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002975
Georg Brandl3ee81df2008-05-17 18:14:43 +00002976- Issue #1686386: Tuple's tp_repr did not take into account the
2977 possibility of having a self-referential tuple, which is possible
2978 from C code. Nor did object's tp_str consider that a type's tp_str
2979 could do something that could lead to an inifinite recursion.
2980 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2981 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002982
Georg Brandl3ee81df2008-05-17 18:14:43 +00002983- Issue #1164: It was possible to trigger deadlock when using the
2984 'print' statement to write to a file since the GIL was not released
2985 as needed. Now PyObject_Print() does the right thing along with
2986 various tp_print implementations of the built-in types and those in
2987 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002988
Georg Brandl3ee81df2008-05-17 18:14:43 +00002989- Issue #1147: Exceptions were directly allowing string exceptions in

2991 allowed.

Brett Cannon1e534b52007-09-07 04:18:30 +00002996- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002997 PyObject_Call() never calling back out to Python code to trigger
2998 recursion depth updates/checks. Required the creation of a static
2999 RuntimeError instance in case normalizing an exception put the
3000 recursion check value past its limit. Fixes crashers
3001 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00003016- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003017 __*__ attributes. (Some already existed, e.g., __doc__ and
3018 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003019
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003020- Add -3 option to the interpreter to warn about features that are
3021 deprecated and will be changed/removed in Python 3.0.
3022
Georg Brandl2134e752007-05-21 20:34:16 +00003023- Patch #1686487: you can now pass any mapping after '**' in function
3024 calls.
3025
Collin Winter62903052007-05-18 23:11:24 +00003026- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003027 "except E as target:". This is to provide forwards compatibility
3028 with Python 3.0.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003032- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003033 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00003035- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003036 setting a plain string, ie don't expand to single letter identifiers.
3037
Raymond Hettinger13936692007-04-11 18:40:58 +00003038- Request #1191699: Slices can now be pickled.
3039
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003040- Request #1193128: str.translate() now allows a None argument for
3041 translations that only remove characters without re-mapping the
3042 remaining characters.
3043
Georg Brandl5cb76c12007-03-21 09:00:39 +00003044- Patch #1682205: a TypeError while unpacking an iterable is no longer
3045 masked by a generic one with the message "unpack non-sequence".
3046
Neal Norwitzaa754b72007-03-21 06:39:48 +00003047- Remove unused file Python/fmod.c.
3048
Guido van Rossum143b5642007-03-23 04:58:42 +00003049- Bug #1683368: The object.__init__() and object.__new__() methods are
3050 now stricter in rejecting excess arguments. The only time when
3051 either allows excess arguments is when it is not overridden and the
3052 other one is. For backwards compatibility, when both are
3053 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003054 warning later). Also, type.__init__() insists on the same signature
3055 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003056
Georg Brandl3ee81df2008-05-17 18:14:43 +00003057- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3058 object to complex using its __complex__() method before falling back
3059 to the __float__() method. Therefore, the functions in the cmath
3060 module now can operate on objects that define a __complex__()
3061 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003062
Georg Brandl3ee81df2008-05-17 18:14:43 +00003063- Patch #1623563: allow __class__ assignment for classes with
3064 __slots__. The old and the new class are still required to have the
3065 same slot names.

3071 ``object.__reduce_ex__()`` is called with an object that is faking
3072 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003073
Georg Brandl3ee81df2008-05-17 18:14:43 +00003074- Patch #1680015: Don't modify __slots__ tuple if it contains an

3078
Georg Brandl7b9c5552007-03-12 14:30:05 +00003079- Bug #1678647: write a newline after printing an exception in any
3080 case, even when converting the value to a string failed.
3081
Georg Brandl871f1bc2007-03-12 13:17:36 +00003082- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003083 its argument, if it exists. If not, it will work like before. This
3084 allows customizing the output of dir() in the presence of a
3085 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003086
Collin Winter276887b2007-03-12 16:11:39 +00003087- Patch #922167: Python no longer segfaults when faced with infinitely
3088 self-recursive reload() calls (as reported by bug #742342).
3089

Georg Brandl3ee81df2008-05-17 18:14:43 +00003093- Patch #1491866: change the complex() constructor to allow
3094 parthensized forms. This means complex(repr(x)) now works instead of
3095 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003096
Georg Brandlaa2321b2007-03-07 00:40:28 +00003097- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003098 makes the filenames the warning module prints much more sensible
3099 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003100

3110 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00003111
Georg Brandl0fca97a2007-03-05 22:28:08 +00003112- Patch #1674228: when assigning a slice (old-style), check for the
3113 sq_ass_slice instead of the sq_slice slot.
3114
Georg Brandl3ee81df2008-05-17 18:14:43 +00003115- When printing an unraisable error, don't print exceptions. before
3116 the name. This duplicates the behavior whening normally printing
3117 exceptions.

3742 TestCase and TestSuite subclasses (not instances) are no longer

3745 -- the failure just occurred later, with a more cumbersome
3746 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004027- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4028 with RFC 3207 and forgets any knowledge obtained from the server not
4029 obtained from the TLS negotiation itself. Patch contributed by Bill
4030 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004031
Georg Brandl3ee81df2008-05-17 18:14:43 +00004032- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004033 that the SMTP.starttls() caller no longer needs to call ehlo()
4034 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004035 does not claim to support starttls. Adds the
4036 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4117 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4118 silently miscode subclasses of those types. Now, it raises a
4119 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004120

Georg Brandl3ee81df2008-05-17 18:14:43 +00004135 time so that opening a database previously created with the DB_DUP
4136 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4137 opens. Specifically: dictionary assignment to a DB object will
4138 replace all values for a given key when the database allows
4139 duplicate values. DB users should use DB.put(k, v) when they want
4140 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004141

4147 characters with ASCII value less than 32. Also, it correctly quotes
4148 dots only if they occur on a single line, as opposed to the previous
4149 behavior of quoting dots if they are the second character of any
4150 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004151
Georg Brandla47337f2007-03-13 12:34:25 +00004152- Bug #1622896: fix a rare corner case where the bz2 module raised an

4412
Guido van Rossum7c862f82007-12-13 20:50:10 +00004413- Bug #1608: use -fwrapv when GCC supports it. This is important,

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004419- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00004420 periodic threadstate and signal checking in tight loops. By
4421 default, this option is turned-off. It should only be enabled in
4422 debugged, performance critical applications.

4473-----
4474
Georg Brandl3ee81df2008-05-17 18:14:43 +00004475- Unified naming convention for free lists and their limits. All free
4476 lists in Object/ are named ``free_list``, the counter ``numfree``
4477 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4478 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004479
Georg Brandl3ee81df2008-05-17 18:14:43 +00004480- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4481 to ``PyTuple_SetItem``, it can be used to populate a brand new
4482 frozenset; but it does not steal a reference to the added item.

4491
4492- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4493 ``PyFloat_GetInfo()`` to the float API.
4494
Georg Brandl3ee81df2008-05-17 18:14:43 +00004495- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4496 of w# format code incorrectly truncated the length to an int, even
4497 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4498 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004499
Georg Brandl3ee81df2008-05-17 18:14:43 +00004500- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4520
4521- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4522 outside of pystate.c and should not be necessary.
4523
Georg Brandl3ee81df2008-05-17 18:14:43 +00004524- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4525 absolute imports. In earlier versions they might have used relative
4526 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004527
Georg Brandl3ee81df2008-05-17 18:14:43 +00004528- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4529 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004530
Georg Brandl3ee81df2008-05-17 18:14:43 +00004531- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004556- Removed the macfs module. It had been deprecated since Python 2.5.
4557 This lead to the deprecation of macostools.touched() as it relied
4558 solely on macfs and was a no-op under OS X.
