1071- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
1072 302 conformant loader) will now work correctly in most cases (they

1233What's New in Python 2.6.1
1234==========================
1235
1236*Release date: 04-Dec-2008*
1237
1238Core and Builtins
1239-----------------
1240
1241- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1242 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1243 instead of throwing a MemoryError.
1244
1245- Issue #4367: Python would segfault during compiling when the unicodedata
1246 module couldn't be imported and \N escapes were present.
1247
1248- Issue #4348: Some bytearray methods returned that didn't cause any change to
1249 the bytearray, returned the same bytearray instead of a copy.
1250
1251- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1252
1253- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1254
1255- Issue #4048: The parser module now correctly validates relative imports.
1256
1257- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1258 exec statement.
1259
1260- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1261 method does not return iterators for the 4th and 5th items.
1262
1263- Issue #4209: Enabling unicode_literals and the print_function in the same
1264 __future__ import didn't work.
1265
1266- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1267 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1268 really executed because I cannot move to such directory on win2k)
1269
1270- Issue #4069: When set.remove(element) is used with a set element, the element
1271 is temporarily replaced with an equivalent frozenset. But the eventual
1272 KeyError would always report the empty frozenset([]) as the missing key. Now
1273 it correctly refers to the initial element.
1274
1275- Fixed C99 style comments in several files. Python is now C89 compatible
1276 again.
1277
1278Library

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001423- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1424
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001425- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1426 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1427 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1428 ``printf`` function, whereas PyString_FromFormat has an independent
1429 implementation and uses "%zd" on all platforms for size_t values.
1430 This makes a difference on win64, where ``printf`` needs "%Id" to display
1431 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001433- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1437 object; previously an int would be returned for small values. the __long__
1438 method is allowed to return either an int or a long, but the behaviour of
1439 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001441- Issue #3751: str.rpartition would perform a left-partition when called with

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001448 was correctly parsed but parsing of subsequent arguments failed.
1449
Vinay Sajip35e3b032008-09-01 14:33:59 +00001450- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001451 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1452 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1453 when given a tuple of classes as second argument, were looking up
1454 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1455 type object.
1456
Neal Norwitz18aa3882008-08-24 05:04:52 +00001457- Fix crashes on memory allocation failure found with failmalloc.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001591What's New in Python 2.6 beta 3?
1592================================
1593
Barry Warsaw07a4a382008-08-21 01:15:08 +00001594*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001595
1596Core and Builtins
1597-----------------
1598
Guido van Rossumf8402962008-08-20 15:01:50 +00001599- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1600 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1601 extensions do not automatically benefit from the class attribute
1602 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1603 to their tp_flags field if they care. This is a backwards
1604 compatibility feature; in 3.0, all types will use the cache by
1605 default.
1606
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001607- Keyword arguments can now follow starred arguments. (``f(a, *args,
1608 keyword=23)`` is now valid syntax.)
1609
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001610- ctypes function pointers that are COM methods have a boolean True
1611 value again.
1612
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001613- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1614 by denying s# to parse objects that have a releasebuffer procedure,
1615 and introducing s*.
1616
Georg Brandl1e13ea92008-08-11 09:07:59 +00001617- Issue #3537: Fix an assertion failure when an empty but presized dict
1618 object was stored in the freelist.
1619
Mark Dickinsonb6467572008-08-04 21:30:09 +00001620- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1621 ValueError consistently across platforms.
1622
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001623- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1624 (64bit Unix, for example), unichr() would truncate its argument and return
1625 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1626
Neal Norwitze7d8be82008-07-31 17:17:14 +00001627- Apply security patches from Apple.
1628
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001629- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1630 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1631
Antoine Pitrou92f82162008-07-25 22:22:08 +00001632- Issue #1819: function calls with several named parameters are now on
1633 average 35% faster (as measured by pybench).
1634
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001635- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1636 the python debugger steps into a class statement: the free variables (local
1637 variables defined in an outer scope) would be deleted from the outer scope.
1638
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001639- Issue #2620: Overflow checking when allocating or reallocating memory
1640 was not always being done properly in some python types and extension
1641 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1642 all been updated to perform better checks and places in the code that
1643 would previously leak memory on the error path when such an allocation
1644 failed have been fixed.
1645
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001646Library
1647-------
1648
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001649- Issue #3612: Added some missing basic types in ctypes.wintypes.
1650
Benjamin Petersone977ad42008-08-20 01:42:01 +00001651- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1652 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1653
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001654- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1655 version reported by these tools does not necessarily follow the python
1656 version numbering scheme, so the module is less strict when parsing it.
1657
Nick Coghlanf70385a2008-08-18 12:42:46 +00001658- Issue #2235: Added Py3k warnings for types which will become unhashable
1659 under the stricter __hash__ inheritance rules in 3.0. Several types
1660 which did not meet the rules for hash invariants and were already
1661 unhashable in 3.0 have now been explicitly flagged as unhashable in
1662 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1663 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1664
Brett Cannon88f801d2008-08-18 00:46:22 +00001665- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1666 imported into the module but exposed as part of the module's API.
1667
Brett Cannon7b96f072008-08-18 00:41:11 +00001668- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1669
Brett Cannon46225e72008-08-18 00:36:52 +00001670- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1671
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001672- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1673
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001674- Issue #3575: Incremental decoder's decode function now takes bytearray
1675 by using 's*' instead of 't#'.
1676
Jesus Cea585ad8a2009-07-02 15:37:21 +00001677- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001678 fails unicode conversion on 2nd parameter. (windows only)
1679
Facundo Batista94f243a2008-08-17 03:38:39 +00001680- Issue 2464. urllib2 now supports a malformation in the URL received
1681 in a redirect.
1682
Brett Cannonabe423e2008-08-16 21:47:07 +00001683- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001684 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001685
Facundo Batistaeb90b782008-08-16 14:44:07 +00001686- Issue #2776: fixed small issue when handling an URL with double slash
1687 after a 302 response in the case of not going through a proxy.
1688
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001689- Issue #2676: in the email package, content-type parsing was hanging on
1690 pathological input because of quadratic or exponential behaviour of a
1691 regular expression.
1692
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001693- Issue #3476: binary buffered reading through the new "io" library is now
1694 thread-safe.
1695
Brett Cannonbf3157b2008-08-14 05:00:03 +00001696- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1697 since mimetools itself is deprecated. Because modules are cached, all
1698 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1699
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001700- Issue #3134: shutil referenced undefined WindowsError symbol.
1701
Robert Schuppenies14646332008-08-10 11:01:53 +00001702- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1703 menu entries were not deleted.
1704
Brett Cannon83e81842008-08-09 23:30:55 +00001705- Copied the implementation of reduce() to _functools.reduce() to have a
1706 version that did not raise a DeprecationWarning under -3.
1707
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001708- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1709 a MemoryError rather than silently stop the iteration.
1710
Guido van Rossum59ce9012008-08-09 14:55:34 +00001711- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1712 to _sre.compile() will now be rejected. This should not affect anybody
1713 since the re.compile() function never generates invalid re-bytecode.
1714
Skip Montanaroa032bf42008-08-08 22:52:51 +00001715- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1716 upon first access it can be automatically initialized from the csv file if
1717 it wasn't initialized during instantiation.
1718
Brett Cannon3aa2a492008-08-06 22:28:09 +00001719- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1720 the reload() built-in has been removed.
1721
Brett Cannon7e30b672008-08-04 21:52:25 +00001722- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001723 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00001724 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
1725 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
1726 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
1727 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1728 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00001729
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001730- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1731 raised an AttributeError.
1732
Benjamin Peterson01a24322008-07-28 23:35:27 +00001733- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001734 asking for a specific length. This problem only affected files opened
1735 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001736
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001737- Issue #3449: Update decimal module to use most recent specification
1738 (v. 1.68) and tests (v. 2.58) from IBM.
1739
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001740- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
1741
Raymond Hettinger8c664e82008-07-25 18:43:33 +00001742- Issue 1592: Improve error reporting when operations are attempted
1743 on a closed shelf.

1746
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001747- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
1748
1749- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1750 invalid arguments.
1751
1752- Issue #3302: Fix several crashes when calling locale's gettext functions
1753 with None arguments.
1754
1755- Issue #3389: Allow resolving dotted names for handlers in logging
1756 configuration files.
1757
1758- Deprecate the sunaudio module for removal in Python 3.0.
1759
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001760- Issue #3394: zipfile.writestr sets external attributes when passed a
1761 file name rather than a ZipInfo instance, so files are extracted with
1762 mode 0600 rather than 000 under Unix.
1763
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001764- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1765 argument in python 2.5, this broke code that subclassed Popen to include its
1766 own poll method. Fixed my moving _deadstate to an _internal_poll method.
1767

1774-------------
1775
Nick Coghlan6e8fef02008-08-18 13:14:22 +00001776- Issue #2235: the C API function PyObject_HashNotImplemented and its
1777 interaction with the tp_hash slot (added in 2.6b2) are now documented
1778
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001779- Issue #643841: The language reference now provides more detailed
1780 coverage of the lookup process for special methods. The disclaimers
1781 regarding lack of coverage of new-style classes have also been
1782 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001785What's New in Python 2.6 beta 2?
1786================================
1787
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001788*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001790Core and Builtins
1791-----------------
1792
Georg Brandl3e483f62008-07-16 22:57:41 +00001793- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1794 its methods now allow for items objects that can be converted to
1795 an integer using operator.index().
1796
Mark Dickinson64b7e502008-07-16 09:40:03 +00001797- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1798 produced a ValueError instead of giving the correct float.
1799
Eric Smitha5fa5a22008-07-16 00:11:49 +00001800- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1801 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1802
Mark Dickinson7103aa42008-07-15 19:08:33 +00001803- Issue #3008: the float type has a new instance method 'float.hex'
1804 and a new class method 'float.fromhex' to convert floating-point
1805 numbers to and from hexadecimal strings, respectively.
1806
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001807- Issue #2235: __hash__ is once again inherited by default. To allow
1808 collections.Hashable to remain meaningful in the presence of the
1809 default hash implementation (object.__hash__), it is now possible
1810 to explicit block inheritance of hash by setting __hash__=None at
1811 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1812 level.
1813
Nick Coghlanb028f502008-07-13 14:52:36 +00001814- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1815 the parent module cannot be found while performing an absolute import.
1816 This means that an incorrectly defined __package__ attribute will
1817 now only prevent relative imports in that module rather than causing
1818 all imports from that module to fail.
1819
Nick Coghlan14ff9942008-07-08 14:21:42 +00001820- Issue #2517: Allow unicode messages in Exceptions again by correctly
1821 bypassing the instance dictionary when looking up __unicode__ on
1822 new-style classes.
1823
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001824- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1825 set to a custom object whose write() method happens to install
1826 another file in sys.stdout.
1827
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001828- Issue #3088: Corrected a race condition in classes derived from
1829 threading.local: the first member set by a thread could be saved in
1830 another thread's dictionary.
1831
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001832- Issue #3004: Minor change to slice.indices(): the start and stop
1833 arguments are now treated identically, making the behaviour easier
1834 to describe and understand. For example, slice(None, -10,
1835 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1836 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1837 10, -1).
1838
Georg Brandl278fc502008-07-19 12:46:12 +00001839- Issue #3219: Calling a function with repeated keyword arguments,
1840 f(a=2, a=23), would not cause a syntax error. This was a regression
1841 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001842
Georg Brandl278fc502008-07-19 12:46:12 +00001843- Issue #2862: Make int and float freelist management consistent with
1844 other freelists. Changes their CompactFreeList apis into
1845 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00001850- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1851 api functions without holding the GIL, which could lead to a fatal
1852 error when they failed.
1853
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001854- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00001862- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1863 ForkingPickler.register() to resolve conflict with ctypes.
1864
Vinay Sajip51e65192008-07-18 09:01:10 +00001865- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

1868 a valid dlerror() message.
1869
Thomas Heller2bad6572008-07-15 17:19:50 +00001870- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1871 incomplete structure was created.
1872
Brett Cannon3d0b9f02008-07-13 01:15:07 +00001873- Issue #3339: dummy_thread.acquire() should not return None.
1874
Raymond Hettingerb01713e2008-07-10 14:34:57 +00001875- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
1876

2288
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002289- On MacOS X it is now possible to install the framework in 64-bit
2290 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002291 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002292
2293 This is controlled by the configure argument ``--with-universal-archs``:
2294
2295 - ``--with-universal-archs=all``: install 4-way universal
2296
2297 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2298
2299 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2300
2301 This option should be used in combination with ``--enable-universalsdk=``.
2302
2303 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00002339- Issue #2670: Fix a failure in urllib2.build_opener(), when passed
2340 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00002341
Christian Heimese74c8f22008-04-19 02:23:57 +00002342- Added kill, terminate and send_signal(sig) to subprocess.Popen.
2343
Georg Brandl3ee81df2008-05-17 18:14:43 +00002344- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
2345 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00002346
Georg Brandl3ee81df2008-05-17 18:14:43 +00002347- Four new methods were added to the math and cmath modules: acosh,

Georg Brandl3ee81df2008-05-17 18:14:43 +00002353- Issue #1631171: Re-implement the 'warnings' module in C (the
2354 original Python code has been kept as backup). This will allow for
2355 using the 'warning's machinery in such places as the parser where
2356 use of pure Python code is not possible. Both the ``showarning()``
2357 and ``formatwarning()`` gain an optional 'line' argument which is
2358 not called by default for backwards-compatibility reasons. Setting
2359 ``warnings.showwarning()`` to an implementation that lacks support
2360 for the ``line`` argument will raise a DeprecationWarning.

Neal Norwitz2b0bea52008-04-25 03:40:17 +00002382- Issue #2682: ctypes callback functions no longer contain a cyclic
Thomas Hellerbf027c42008-04-24 18:14:19 +00002383 reference to themselves.
2384
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002385- The getpass module has been improved on Unix. It now uses /dev/tty
2386 by default and uses stderr instead of stdout. A GetPassWarning is
2387 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00002388

2399 implementation detail of the public ``types`` module, has been
2400 removed and replaced by pure python code.
Amaury Forgeot d'Arc02f33b42008-04-08 23:10:07 +00002401
Georg Brandl3ee81df2008-05-17 18:14:43 +00002402- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002403 extension modules between 32 and 64 bit platforms. See the distutls
2404 build documentation for more information.

2416 so the controlled environment will more closely mirror the typical
2417 script environment. This supports setup.py scripts that refer to
2418 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002423- Issue #2550: The approach used by client/server code for obtaining
2424 ports to listen on in network-oriented tests has been refined in an
2425 effort to facilitate running multiple instances of the entire
2426 regression test suite in parallel without issue.
2427 test_support.bind_port() has been fixed such that it will always
2428 return a unique port -- which wasn't always the case with the
2429 previous implementation, especially if socket options had been set
2430 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2431 new implementation of bind_port() will actually raise an exception
2432 if it is passed an AF_INET/SOCK_STREAM socket with either the
2433 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2434 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2435 the socket it's been passed. This currently only applies to
2436 Windows. This option prevents any other sockets from binding to the
2437 host/port we've bound to, thus removing the possibility of the
2438 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2439 when a second SOCK_STREAM socket binds and accepts to a host/port
2440 that's already been bound by another socket. The optional preferred
2441 port parameter to bind_port() has been removed. Under no
2442 circumstances should tests be hard coding ports!
2443
2444 test_support.find_unused_port() has also been introduced, which will
2445 pass a temporary socket object to bind_port() in order to obtain an
2446 unused port. The temporary socket object is then closed and
2447 deleted, and the port is returned. This method should only be used
2448 for obtaining an unused port in order to pass to an external program
2449 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2450 a parameter to a server-oriented class that doesn't give you direct
2451 access to the underlying socket used.
2452
2453 Finally, test_support.HOST has been introduced, which should be used
2454 for the host argument of any relevant socket calls (i.e. bind and
2455 connect).

2729Core and builtins
2730-----------------
2731
Fred Drakea8ee94b2008-03-01 02:45:07 +00002732- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002733 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002734
Georg Brandlad61bc82008-02-23 15:11:18 +00002735- Issue #2067: file.__exit__() now calls subclasses' close() method.
2736
2737- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002738
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002739- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002740 issue 215555 for a discussion.
2741
Eric Smitha73fbe72008-02-23 03:09:44 +00002742- Added the future_builtins module, which contains hex() and oct().
2743 These are the PEP 3127 version of these functions, designed to be
2744 compatible with the hex() and oct() builtins from Python 3.0. They
2745 differ slightly in their output formats from the existing, unchanged
2746 Python 2.6 builtins. The expected usage of the future_builtins
2747 module is:
2748 from future_builtins import hex, oct
2749
Eric Smith7ef40bf2008-02-20 23:34:22 +00002750- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2751 exponents for exponents with absolute value < 100. Follows C99
2752 standard. This is a change on Windows, which would use 3 digits.
2753 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2754 so that any alterations it does to the resulting string will be
2755 available in stringlib/formatter.h (for float.__format__).
2756
Eric Smith5a3c1352008-02-19 13:21:56 +00002757- Implemented PEP 3101, Advanced String Formatting. This adds a new
2758 builtin format(); a format() method for str and unicode; a
2759 __format__() method to object, str, unicode, int, long, float, and
2760 datetime; the class string.Formatter; and the C API
2761 PyObject_Format().
2762
Georg Brandl3ee81df2008-05-17 18:14:43 +00002763- Fixed several potential crashes, all caused by specially crafted
2764 __del__ methods exploiting objects in temporarily inconsistent
2765 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002766
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002767- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002768 prevent a possible crash: an Abstract Base Class would try to access
2769 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002770
Georg Brandl3ee81df2008-05-17 18:14:43 +00002771- Fixed repr() and str() of complex numbers with infinity or nan as
2772 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002773
Georg Brandl3ee81df2008-05-17 18:14:43 +00002774- Clear all free lists during a gc.collect() of the highest generation
2775 in order to allow pymalloc to free more arenas. Python may give back
2776 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002777
Georg Brandl3ee81df2008-05-17 18:14:43 +00002778- Issue #2045: Fix an infinite recursion triggered when printing a
2779 subclass of collections.defaultdict, if its default_factory is set
2780 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002781
Christian Heimesf75dbef2008-02-08 00:11:31 +00002782- Fixed a minor memory leak in dictobject.c. The content of the free
2783 list was not freed on interpreter shutdown.
2784
Georg Brandl3ee81df2008-05-17 18:14:43 +00002785- Limit free list of method and builtin function objects to 256
2786 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002787
Georg Brandl3ee81df2008-05-17 18:14:43 +00002788- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2789 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002790 to compact the internal free lists of pre-allocted ints and floats.
2791
Georg Brandl3ee81df2008-05-17 18:14:43 +00002792- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2793 calls. Python expected the return type int but the fork familie
2794 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002795
Georg Brandl3ee81df2008-05-17 18:14:43 +00002796- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2797 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002798
Georg Brandl3ee81df2008-05-17 18:14:43 +00002799- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2800 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002801
Georg Brandl3ee81df2008-05-17 18:14:43 +00002802- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2803 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002804
Georg Brandl3ee81df2008-05-17 18:14:43 +00002805- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2806 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002807
Georg Brandl3ee81df2008-05-17 18:14:43 +00002808- Patch #1473257: generator objects gain a gi_code attribute. This is
2809 the same object as the func_code attribute of the function that
2810 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002811
Georg Brandl3ee81df2008-05-17 18:14:43 +00002812- Issue #1920: "while 0" statements were completely removed by the
2813 compiler, even in the presence of an "else" clause, which is
2814 supposed to be run when the condition is false. Now the compiler
2815 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002816
Guido van Rossumeead05f2008-01-24 18:21:02 +00002817- A few crashers fixed: weakref_in_del.py (issue #1377858);
2818 loosing_dict_ref.py (issue #1303614, test67.py);
2819 borrowed_ref_[34].py (not in tracker).
2820
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002821- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002822 suppressed while an extension is loaded by calling SetErrorMode in
2823 dynload_win.c. The error is still reported properly.
2824
Georg Brandl3ee81df2008-05-17 18:14:43 +00002825- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002826 several extension methods and modules do not work without unicode
2827 support.
2828
Georg Brandl26543b12008-01-21 18:36:51 +00002829- Issue #1882: when compiling code from a string, encoding cookies in the
2830 second line of code were not always recognized correctly.
2831
Georg Brandl14404b62008-01-19 19:27:05 +00002832- Issue #1679: "0x" was taken as a valid integer literal.
2833
Georg Brandl6caad7d2008-01-26 14:19:22 +00002834- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002835 added.
2836
Christian Heimesc94e2b52008-01-14 04:13:37 +00002837- sys.float_info / PyFloat_GetInfo: The floating point information
2838 object was converted from a dict to a specialized structseq object.
2839
Georg Brandl3ee81df2008-05-17 18:14:43 +00002840- Patch #1816: Added sys.flags structseq. It exposes the status of
2841 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002842
Georg Brandl3ee81df2008-05-17 18:14:43 +00002843- Objects/structseq.c: Implemented new structseq representation. The
2844 patch makes structseqs (e.g. the return value of os.stat) more
2845 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002846
Georg Brandl3ee81df2008-05-17 18:14:43 +00002847- Patch #1700288: added a type attribute cache that caches method
2848 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002849
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002850- Bug #1776: __import__() no longer accepts filenames on any platform.
2851 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002852
Georg Brandlaed6c662008-01-07 17:25:53 +00002853- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2854
Georg Brandl3ee81df2008-05-17 18:14:43 +00002855- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2856 envvar and sys.dont_write_bytecode attribute. All these can be set
2857 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002858
Georg Brandl3ee81df2008-05-17 18:14:43 +00002859- Improve some exception messages when Windows fails to load an
2860 extension module. Now we get for example '%1 is not a valid Win32
2861 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002862
Georg Brandl3ee81df2008-05-17 18:14:43 +00002863- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002865- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2866 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002867
Christian Heimes0a8143f2007-12-18 23:22:54 +00002868- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002869 and INF. float("nan"), float("inf") and float("-inf") now work on
2870 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002871
Georg Brandl3ee81df2008-05-17 18:14:43 +00002872- Compiler now generates simpler and faster code for dictionary
2873 literals. The oparg for BUILD_MAP now indicates an estimated
2874 dictionary size. There is a new opcode, STORE_MAP, for adding
2875 entries to the dictionary.

2893 running, and if the deallocation of its frames somehow calls the
2894 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002895

2905 file can now be directly executed by passing their name to the
2906 interpreter. The directory/zipfile is automatically inserted as the
2907 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002908
Georg Brandl3ee81df2008-05-17 18:14:43 +00002909- Issue #1265: Fix a problem with sys.settrace, if the tracing
2910 function uses a generator expression when at the same time the
2911 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002912
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002913- sets and frozensets now have an isdisjoint() method.
2914
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002915- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00002917- Fix warnings found by the new version of the Coverity checker.
2918
Georg Brandl3ee81df2008-05-17 18:14:43 +00002919- The enumerate() builtin function is no longer bounded to sequences
2920 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2921 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002922
Georg Brandl3ee81df2008-05-17 18:14:43 +00002923- Issue #1686386: Tuple's tp_repr did not take into account the
2924 possibility of having a self-referential tuple, which is possible
2925 from C code. Nor did object's tp_str consider that a type's tp_str
2926 could do something that could lead to an inifinite recursion.
2927 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2928 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002929
Georg Brandl3ee81df2008-05-17 18:14:43 +00002930- Issue #1164: It was possible to trigger deadlock when using the
2931 'print' statement to write to a file since the GIL was not released
2932 as needed. Now PyObject_Print() does the right thing along with
2933 various tp_print implementations of the built-in types and those in
2934 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002936- Issue #1147: Exceptions were directly allowing string exceptions in
2937 their throw() method even though string exceptions no longer
2938 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002939
Georg Brandl3ee81df2008-05-17 18:14:43 +00002940- Issue #1096: Prevent a segfault from getting the repr of a very
2941 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002942
Brett Cannon1e534b52007-09-07 04:18:30 +00002943- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002944 PyObject_Call() never calling back out to Python code to trigger
2945 recursion depth updates/checks. Required the creation of a static
2946 RuntimeError instance in case normalizing an exception put the
2947 recursion check value past its limit. Fixes crashers
2948 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002949

Neal Norwitz0ac60192007-05-27 04:08:54 +00002963- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002964 __*__ attributes. (Some already existed, e.g., __doc__ and
2965 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002966
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002967- Add -3 option to the interpreter to warn about features that are
2968 deprecated and will be changed/removed in Python 3.0.
2969

2971 calls.
2972
Collin Winter62903052007-05-18 23:11:24 +00002973- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002974 "except E as target:". This is to provide forwards compatibility
2975 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002976
Brett Cannon229cee22007-05-05 01:34:02 +00002977- Deprecate BaseException.message as per PEP 352.
2978
Georg Brandl3ee81df2008-05-17 18:14:43 +00002979- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002980 inherited from a builtin base.
2981
Vinay Sajip8549ce32007-05-06 17:53:37 +00002982- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002983 setting a plain string, ie don't expand to single letter identifiers.
2984
Raymond Hettinger13936692007-04-11 18:40:58 +00002985- Request #1191699: Slices can now be pickled.
2986
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002987- Request #1193128: str.translate() now allows a None argument for
2988 translations that only remove characters without re-mapping the
2989 remaining characters.
2990
Georg Brandl5cb76c12007-03-21 09:00:39 +00002991- Patch #1682205: a TypeError while unpacking an iterable is no longer
2992 masked by a generic one with the message "unpack non-sequence".
2993
Neal Norwitzaa754b72007-03-21 06:39:48 +00002994- Remove unused file Python/fmod.c.
2995
Guido van Rossum143b5642007-03-23 04:58:42 +00002996- Bug #1683368: The object.__init__() and object.__new__() methods are
2997 now stricter in rejecting excess arguments. The only time when
2998 either allows excess arguments is when it is not overridden and the
2999 other one is. For backwards compatibility, when both are
3000 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003001 warning later). Also, type.__init__() insists on the same signature
3002 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003003
Georg Brandl3ee81df2008-05-17 18:14:43 +00003004- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3005 object to complex using its __complex__() method before falling back
3006 to the __float__() method. Therefore, the functions in the cmath
3007 module now can operate on objects that define a __complex__()
3008 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003009
Georg Brandl3ee81df2008-05-17 18:14:43 +00003010- Patch #1623563: allow __class__ assignment for classes with
3011 __slots__. The old and the new class are still required to have the
3012 same slot names.

3018 ``object.__reduce_ex__()`` is called with an object that is faking
3019 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003020
Georg Brandl3ee81df2008-05-17 18:14:43 +00003021- Patch #1680015: Don't modify __slots__ tuple if it contains an

3025
Georg Brandl7b9c5552007-03-12 14:30:05 +00003026- Bug #1678647: write a newline after printing an exception in any
3027 case, even when converting the value to a string failed.
3028
Georg Brandl871f1bc2007-03-12 13:17:36 +00003029- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003030 its argument, if it exists. If not, it will work like before. This
3031 allows customizing the output of dir() in the presence of a
3032 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003033
Collin Winter276887b2007-03-12 16:11:39 +00003034- Patch #922167: Python no longer segfaults when faced with infinitely
3035 self-recursive reload() calls (as reported by bug #742342).
3036

3041 parthensized forms. This means complex(repr(x)) now works instead of
3042 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003043
Georg Brandlaa2321b2007-03-07 00:40:28 +00003044- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003045 makes the filenames the warning module prints much more sensible
3046 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003047
Georg Brandl49aafc92007-03-07 00:34:46 +00003048- Variant of patch #697613: don't exit the interpreter on a SystemExit
3049 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003050 variable is given, but break into the interactive interpreter just
3051 like on other exceptions or normal program exit.

3057 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00003058
Georg Brandl0fca97a2007-03-05 22:28:08 +00003059- Patch #1674228: when assigning a slice (old-style), check for the
3060 sq_ass_slice instead of the sq_slice slot.
3061
Georg Brandl3ee81df2008-05-17 18:14:43 +00003062- When printing an unraisable error, don't print exceptions. before
3063 the name. This duplicates the behavior whening normally printing
3064 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003072- Bug #1377858: Fix the segfaulting of the interpreter when an object
3073 created a weakref on itself during a __del__ call for new-style
3074 classes (classic classes still have the bug).

3673 Python would crash instead of raising an error.
3674
Thomas Hellerc2f77252007-03-09 19:21:28 +00003675- Bug #1646630: ctypes.string_at(buf, 0) and ctypes.wstring_at(buf, 0)
3676 returned string up to the first NUL character.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003688- unittest now verifies more of its assumptions. In particular,
3689 TestCase and TestSuite subclasses (not instances) are no longer
3690 accepted in TestSuite.addTest(). This should cause no
3691 incompatibility since it never made sense with ordinary subclasses
3692 -- the failure just occurred later, with a more cumbersome
3693 exception.

Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003978
Georg Brandl3ee81df2008-05-17 18:14:43 +00003979- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003980 that the SMTP.starttls() caller no longer needs to call ehlo()
3981 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003982 does not claim to support starttls. Adds the
3983 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4064 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4065 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00004082 time so that opening a database previously created with the DB_DUP
4083 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4084 opens. Specifically: dictionary assignment to a DB object will
4085 replace all values for a given key when the database allows
4086 duplicate values. DB users should use DB.put(k, v) when they want
4087 to store duplicates; not DB[k] = v.

4094 characters with ASCII value less than 32. Also, it correctly quotes
4095 dots only if they occur on a single line, as opposed to the previous
4096 behavior of quoting dots if they are the second character of any
4097 line.

4420-----
4421
Georg Brandl3ee81df2008-05-17 18:14:43 +00004422- Unified naming convention for free lists and their limits. All free
4423 lists in Object/ are named ``free_list``, the counter ``numfree``
4424 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4425 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004426
Georg Brandl3ee81df2008-05-17 18:14:43 +00004427- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4428 to ``PyTuple_SetItem``, it can be used to populate a brand new
4429 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004430
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004431- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004433- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
4434 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4435 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004436
4437- Patch #1720595: add T_BOOL to the range of structmember types.
4438
4439- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4440 ``PyFloat_GetInfo()`` to the float API.
4441
Georg Brandl3ee81df2008-05-17 18:14:43 +00004442- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4443 of w# format code incorrectly truncated the length to an int, even
4444 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4445 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004446
Georg Brandl3ee81df2008-05-17 18:14:43 +00004447- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4448 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004450- PEP 3123: Provide forward compatibility with Python 3.0, while
4451 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4452 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004453
Georg Brandl3ee81df2008-05-17 18:14:43 +00004454- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4455 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004456
4457- Patch #1733960: Allow T_LONGLONG to accept ints.
4458

4464
4465- Fix some leftovers from the conversion from int to Py_ssize_t
4466 (relevant to strings and sequences of more than 2**31 items).
4467
4468- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4469 outside of pystate.c and should not be necessary.
4470
Georg Brandl3ee81df2008-05-17 18:14:43 +00004471- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4472 absolute imports. In earlier versions they might have used relative
4473 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004474
Georg Brandl3ee81df2008-05-17 18:14:43 +00004475- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4476 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004477
Georg Brandl3ee81df2008-05-17 18:14:43 +00004478- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
4479 macro so it can be used as an expression.

4484
Georg Brandl3ee81df2008-05-17 18:14:43 +00004485- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4486 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4487 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4488 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004489
Georg Brandl3ee81df2008-05-17 18:14:43 +00004490- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00004503- Removed the macfs module. It had been deprecated since Python 2.5.
4504 This lead to the deprecation of macostools.touched() as it relied
4505 solely on macfs and was a no-op under OS X.
